018ffd0c-e34a-b843-1e96-b981ecae6b11 | Thus, it is recommended that a cantilever be used in buccally or lingually placed impacted canines that need to be lingually or labially repositioned, respectively. A cantilever allows a system of forces to be applied in the desired direction, which may be determined by the method of preactivation. A cantilever may be replaced by a rectangular loop, provided that the crown of the canine is apparent and its movement may be three-dimensionally controlled until correct positioning is achieved in the dental arch. | Segmented arch or continuous arch technique?

0193e202-6388-3a0b-751b-64adf06e9baf | A kinematic model was created for the trunk and pelvis and applied to the sitting posture and trunk flexibility data. The acromion process and iliac crest markers were used to define the proximal and distal ends of the trunk and the cluster of four markers on the upper thorax were used to track trunk movements. The iliac crest and greater trochanter markers defined the proximal and distal ends of the pelvis and these markers together with the PSIS markers were used to track the pelvis. A 4th order Butterworth filter (Robertson and Dowling, 2003) with cut off frequency of 5 Hz was applied to markers tracking trunk motion during the trunk flexibility tests to remove higher frequency noise within the data. A 5 Hz cut off was chosen as this retained 95% of the signal power. For standing and seated posture absolute position of the markers on the left and right acromion processes and iliac crests in the vertical direction were extracted. For trunk lateral bending and rotation, the range of motion of the trunk relative to the pelvis was extracted using an XYZ Cardan sequence, where X was flexion-extension, Y was lateral bending and Z was rotation. The sign convention was based on the right handed rule: in lateral bending right shoulder downwards was positive (right lateral bending) and in rotation right shoulder rotating anticlockwise when viewed from above was positive (right rotation). | Posture, Flexibility and Grip Strength in Horse Riders |

019bcf79-a982-06f0-f39b-c5bc863cde5a | Temporary shunts are a tool that can potentially shorten the duration of ischemia. Glass et al.20 proposed an evidence-based algorithm in which revascularization using a vascular shunt must precede bone fixation. At our institution, use of temporary shunts was mostly reserved for damage control scenarios as we do not systematically use them to shorten the ischemia duration in cases in which there is an associated fracture. Our local practice reflects findings from a retrospective multicenter study by Inaba et al.,21 in which use of shunts was more frequent for damage control procedures compared to temporary use to shorten the ischemia duration in cases of associated fracture. This concept of “vessel first” when there is an associated bone fracture requiring surgical fixation is an area that warrants consideration at our institution. | Prognostic factors in treatment of traumatic femoropopliteal arterial injuries at a Brazilian trauma center Fatores prognósticos no tratamento de lesão traumática arterial femoropoplítea em um centro de trauma brasileiro |

01a3352a-aece-1b77-dc5d-4dd3cbbe6acc | Dimethyl fumarate was originally used for treatment of psoriasis. Its success in treating RRMS patients led for its approval as an oral drug to treat MS patients. One mechanism of action that our group pursued is that DMF might enhance natural killer cell lysis of dendritic cells, hence, impeding presenting encephalitogen to autoreactive T cells. Further investigations suggest that DMF may also be used in the oncology field due to its ability to suppress the growth of melanoma cells. On the other hand, it appears that related molecules, such as MMF, may have even more potent antitumor activity than DMF. Although the association among DMF and MMF is at present conjectural, it is documented that MMF has robust antitumor activity by activating natural killer cells to kill tumor cells. This new mechanism of action for MMF should provide imputes for investigating this molecule not only as a therapeutic tool for autoimmune diseases but also for cancer and immunodeficient diseases. Table 1 shows the current knowledge regarding the effects of DMF and MMF on various immune cells. | Utilization of Dimethyl Fumarate and Related Molecules for Treatment of Multiple Sclerosis, Cancer, and Other Diseases |

01a5c52c-20ce-a48a-d244-ac5f42ed98cb | Although the hospital has eight operating rooms, due to lack of resources only three to four operating rooms are functional. On a daily basis two operating rooms are used exclusively for ambulatory surgery and one for inpatients. The fourth operating room will be usually utilized by special programmes such as cardiac surgery, which is run as a quasi-private programme and hence was not included in the present study. The scheduled operating lists are sent from the Department of Surgery to the sister-in-charge of the operating rooms who manages the floor of the operating rooms. Due to consistent lack of resources there has been a problem in distributing the available operating time to the various specialties. There have been no structured scheduling procedures and back-up schedules in the event of cancellations. | Evaluation of the utilization of the preanaesthetic clinics in a University teaching hospital |
01a88597-2b69-6a55-194d-793091b9f329 | Commercial 2205 duplex stainless steel with a thickness of 6 mm was selected as the research object, and the ER2209 welding wire with a diameter of 2.5 mm was used for manual argon arc welding. The Ni content of ER2209 welding wire was about 3% higher than that of the base material, which was to promote the transformation of ferrite to austenite in the microstructure of the weld to achieve the purpose of double phase balance of the welded joints. Their chemical composition was determined by the ICP method, as shown in Table 1. | Effect of Mechanical Shock Treatment on Microstructure and Corrosion Properties of Manual Argon Arc Welding Joints of 2205 Duplex Stainless Steel |
01ae979f-5567-7e16-678f-f05a8b56f54e | Participants were free to choose the sequence of touching the rectangles i.e. a subject could start with touching the right rectangle, then continue with touching the left rectangle and the middle one or they could choose any other sequence. Fig 3 shows the distribution of times to reach the three targets. A first hypothesis is that to simplify computation of the movement, the subjects would move the virtual hands in a definite order. If the movements of the three hands would be carried out serially, we would see separated distributions of the arrival to each target. In contrast the overlap of the temporal distributions of reaching the three targets suggests that there is no priority in the sequence of limb actions, and the movements of the three limbs are carried out in parallel. | Control of a Supernumerary Robotic Hand by Foot: An Experimental Study in Virtual Reality |
01b316c0-e701-82e3-89cc-11ee75aba689 | The appliances designed to study in situ biofilms must allow free flow and contact between saliva and the substrate, to permit natural plaque biofilm development, and at the same time protect it from mechanical disturbances. However, some appliances appear to fail due to inherent disturbances associated with the muscular action of the tongue and cheek, thus yielding inconsistent results. Comfort and aesthetics are also very important factors that need to be considered for effective compliance by the volunteers wearing the appliance. | Intraoral appliances for in situ oral biofilm growth: a systematic review JOURNAL OF ORAL MICROBIOLOGY |
01b7c631-b0d1-c62f-ac25-45d62a7fb194 | The participants of the study were asked to use the assigned mouthwash twice a day (morning and evening) after brushing for three weeks consecutively. They were instructed to rinse with 15 mL of the mouthwash for 1 minute followed by expectoration of the residual mouthwash and then avoid eating and drinking till 30 minutes and not using another mouthwash during the study period. Since each bottle contained 250 mL mouthwash, three bottles of the same mouthwash were given to each patient. The protocol of the use of mouthwash was also provided to patients in written form. To avoid the effect of new variables, subjects were asked to continue their usual daily brushing method (tooth brush and dental floss) during the study period. | Effect of Propolis mouthwash on plaque and gingival indices over fixed orthodontic patients |

01bc4ed6-d897-69c6-4a95-15f331e03ac8 | Various tools are used to gain purchase in the broken piece of the canal by press fitting in the hollow part of the nail. Commercially available conical threaded stainless steel extractors that can thread inside the nail are now available. This depends on the fact that most current nails are composed of titanium and aluminum alloys. The stainless steel tip on the extraction bit will displace the metal on the nail and have a wedge effect. The extractor can be pulled with the nail attached to it. Before threading the extractor in the nail, rotational stability of the broken piece has to be maintained. This is usually done by keeping the locking screws in place until the extractor is applied. If no locking screws are inserted in the broken piece, rotational stability can be achieved by a thick Steinman pin introduced in one of the locking holes [2]. | Removal of a Broken Cannulated Intramedullary Nail: Review of the Literature and a Case Report of a New Technique |

01c724dc-b087-3dea-80a1-ecf5d9a75152 | The present study had some potential limitations. The result of the present study was limited to healthy young males. The comparison of the lung function in different postures was not measured to document the effect of slouched position on lung volumes. In addition, the lack of comparative group limits the validity of the present study. Furthermore, quality trials investigating the effect of changing posture on respiratory muscle strength in patients with breathing disorders are recommended. | Effect of Upright and Slouched Sitting Postures on the Respiratory Muscle Strength in Healthy Young Males |
01c9b878-748f-cdb0-4dd2-cea30ae2ee36 | Clinical implications: Proper management of space in the primary and mixed dentitions can prevent unnecessary loss in arch length. Diagnosing and treating space problems requires an understanding of the etiology of crowding and the development of the dentition to render treatment for the mild, moderate and severe crowding cases. Most crowding problems with less than 4.5 mm can be resolved through preservation of the leeway space, regaining space or limited expansion in the late mixed dentition. In cases with 5 to 9 mm of crowding, some can be approached with expansion after thorough diagnosis and treatment planning. Most of these cases will require extraction of permanent teeth to preserve facial esthetics and the integrity of the supporting soft tissue. Sequential proximal stripping is routinely carried out to avoid extraction in borderline cases where space discrepancy is less and reserved for treatment of mild tooth-size/arch-size discrepancies. | Mastering Interproximal Stripping: With Innovations in Slenderization |

01d85e17-4973-24a3-da39-b1d6caba9f96 | Since facial and smile aesthetics are aspects that are highly valued by the population nowadays, and since standards of beauty are not clearly defined, as they depend on social, cultural, individual and professional variables, the aim of this study was to ascertain whether the aesthetic perceptions of the population can be matched to those of dentists and orthodontists and how they relate to the DAI and IOTN-AC indices, in order to make it easier for orthodontists to keep the aesthetic expectations of patients in mind when planning orthodontic treatments. | A comparative study of aesthetic perceptions of malocclusion among general practice dentists, orthodontists and the public using a visual analogue scale (VAS) and the IOTN-AC |
01da7d9e-1ab5-d36f-b813-145526ff5fc5 | The first methods for the assessment of human baroreflex function are based on statistical and spectral analysis of HR. However, such simple linear methods often lack the sensitivity to identify important features of this function in different physiological states. In these states, various systems of the body often change their properties simultaneously, demonstrating coherent and synchronous behavior. When studying such complex collective dynamics, non-linear methods of analysis have certain advantages. An example of such a non-linear method is the method based on the assessment of the degree of synchronization between the processes of autonomic control of HR rate and BP. This method exploits such a sensitive characteristic of the signal as its instantaneous phase. This approach allows us to identify the changes in the degree of coordinated behavior of the studied processes upon modulation of the baroreflex function by the processes of higher nervous activity. | Synchronization of the Processes of Autonomic Control of Blood Circulation in Humans Is Different in the Awake State and in Sleep Stages |

01ec5b6a-fcad-2c19-bea9-144a39ba0650 | In spite of the extensive population-based data available in the United States, there were limitations particularly in estimating disease burden by race due to smaller populations – Asians and American Indians. The major methodological limitations pertained to the different methods used to assign race and ethnicity in the census compared to death certificates; and to the limited population-based information that was available for many conditions for Asians and American Indians. For these last two groups, ratios of YLL to YLD for the overall US population were generally used to estimate the burden due to non-fatal health conditions. Such assumptions introduce a certain level of uncertainty in the estimates and call for caution in the interpretation of small absolute differences in the number of DALYs between different causes. This study provides a benchmark against which to assess future trends in health differentials in the United States and underscores the importance of further research to improve methods, provide stronger empirical evidence and better understanding of major risk factors for poor health outcomes. | The burden of disease and injury in the United States 1996 |

01f4a1ea-f231-2728-6a91-2e8166f2fbf7 | One cannot always take for granted that there is a regular functional relationship between the precision of the test method and the general mean (). In the examined case, both for the standard deviation of repeatability and the standard deviation of reproducibility, based on the results presented in Table 6, it is possible to describe these functional relationships with a straight line with a positive intercept. However, since only four data pairs for repeatability and four data pairs for reproducibility were obtained as a result of the tests, and taking into account that tensile adhesion strength was determined each time, but after different storage conditions of the sample, and the complexity of the measurement procedure and the heterogeneity of the tested material affects measurement variability, another functional relationship may describe this test method. | Assessment of Cementitious Ceramic Tile Adhesives in the Light of Repeatability and Reproducibility of the Tensile Adhesion Strength Measurements |

01f77028-1e32-467f-0a5a-346e9ed87b4c | These contradictory findings can be explained by the fact that the axonal variant of GBS may either improve very slowly and incompletely or may recover rapidly and fully, even more rapidly than demyelinating variant. The possible mechanism of slow and incomplete recovery in most cases of axonal GBS is secondary axonal degeneration. In these patients, full motor recovery requires axonal regeneration which is a slow and incomplete process. On the other hand, rapid recovery in some cases of axonal GBS could be explained by rapid recovery of early reversible conduction block. In these cases, functional conduction block could be caused by deposition of immunoglobulin, complement, and macrophages at the nodes of Ranvier leading to its lengthening and distortion of paranodal myelin. Another possible mechanism involves antigangliosides GMI antibodies, which are frequently detected in the sera of AMAN patients, that impair sodium and potassium channel function in voltage-clamped single fibers. Finally, A Chinese study suggested that one possible explanation of rapid recovery was that degeneration was limited to intramuscular motor terminal nerves and loss of innervation at the neuromuscular junction. | Early electrophysiological study variants and their relationship with clinical presentation and outcomes of patients with Guillain-Barré syndrome |

01f96f11-eb40-2fc8-9521-0a5725404732 | For the model of anterior teeth retraction without power ridge and for the model of anterior teeth no retraction with a single power ridge, the central incisors exhibited crown lingual inclination and relative extrusion. For the model of anterior teeth no retraction with double power ridges, the central incisors tended to have crown labial inclination and relative intrusion. For the model of anterior tooth retraction with double power ridges, the central incisors exhibited a similar trend to the first kind of model, but as the depth of the power ridge increased, there was a gradual decrease in crown retraction value and an increase in crown extrusion value. The simulated results showed that von-Mises stress concentration was observed in the cervical and apical regions of the periodontal ligaments of the central incisors. The clear aligner connection areas of adjacent teeth and power ridge areas also exhibited von-Mises stress concentration and the addition of power ridge caused the clear aligner to spread out on the labial and lingual sides. | Effects of different designs of orthodontic clear aligners on the maxillary central incisors in the tooth extraction cases: a biomechanical study |

Dual implant systems were found to have lower stress and displacement values compared to monoblock structures, indicating a potential advantage in clinical use. However, mono implants may have benefits in cases of immediate teeth loading due to their ability to absorb and distribute occlusal forces better. | Custom-made Subperiosteal Implants: A Finite Element Analysis on Monoblock and Dual Implant Systems in Atrophic Maxilla |

01fd326a-9097-ef57-8f17-4308286f1486 | A second aspect of bibliometrics is oriented to the analysis of the publications’ references in the scientific literature. Thus, in 1927 Gross and Gross made the first count of references appearing in the Journal of the American Chemical Society to study the frequency of their appearance and the sources of their origin, applying the study to the selection of the list of subscriptions of interest [4]. In 1934 Bradford analyzed the distribution of articles in journals by formulating Bradford’s Law of Dispersion, according to which it was evident that a small number of journals accounted for the largest percentage of the bibliography of a specific topic [5]. If scientific journals are arranged in decreasing order of productivity of articles on a given subject, one can distinguish a core of journals more specialized in that subject and several groups containing approximately the same core but distributed in an increasing number of journals. It can be understood as the background of the classification of journals by scientific categories. | The Bibliometric Literature on Scopus and WoS: The Medicine and Environmental Sciences Categories as Case of Study |
01ff108a-cb0c-ab0c-2398-837bdf92cfbf | The magnetic transcutaneous anchored BAHA Attract does not have skin-penetrating abutment. It stimulates the bone by vibration of the fixed magnet through the intact skin. The advantage of transcutaneous bone conduction hearing aids is to reduce partially skin complications compared to a percutaneous abutment and need skin thinning if skin thickness is more than 6 mm. This conventional technique partially improves esthetic results, but a large 8 cm retroauricular scar is still needed. | Minimal invasive pocket technique for magnet bone implant hearing aid without fixation |
0203e753-e17e-22d5-3a3f-591a4bb5f0c8 | Split tooth constitute a reasonable common reason for tooth extraction and this was most common in the fifth decade of life. High index of suspicion may improve early diagnosis of a cracked tooth in order to provide the correct treatment and patient management that will help relieve pain, restore function and improve the prognosis for the tooth and thereby, prevent the progression of the crack to a split. | Analysis of split tooth as an unstudied reason for tooth extraction |
02046638-420a-af4c-dfff-cc828c3013bd | Using the design of the optimal program shown in Figure 5, the cutting fixture for the mandible lesion and the registered fixture for the arrangement of fibula pieces were created to improve the surgical accuracy and efficiency. As a perfect match between the mandible cutting fixture and the surface of the mandible is critical, this study retrieved the points cloud data of the mandible defect area and utilized the data to reconstruct the pad of the cutting fixture. Therefore, the fixture can completely fit onto the surface of the mandible. In order to deal with possible variation of the lesion area found during surgery, the mandible cutting fixture was designed with three cutting grooves, which allowed the cutting to be more flexible when a larger or smaller lesion area was found during the operation. | Study of mandible reconstruction using a fibula flap with application of additive manufacturing technology |

0208e97a-c061-3ede-ef63-d0976d3c513a | Postoperative CT images were measured on the dorsal plane with true lateral view of the positioning of the stifle joint using a DICOM viewer and MPR. Osteotomy inclination angle was calculated from the intersect of a line parallel to the osteotomy and a line in the accurate orientation of the osteotomy (Figure 4). The direction of the osteotomy proximally from the medial cortex to the lateral cortex was defined as a positive angulation. The direction of the osteotomy distally from the medial cortex to the lateral cortex was defined as a negative angulation (26). Data were analyzed for significant differences in the osteotomy inclination angle between the two methods. | Efficacy of a Customized Three-Dimensional Printing Surgical Guide for Tibial Plateau Leveling Osteotomy: A Comparison With Conventional Tibial Plateau Leveling Osteotomy |

020ff049-1ca1-a0d0-cec7-6b7079d83df8 | An important component of surgical planning is the design of surgical aids such as drill or osteotomy guides and the design of custom implants. One of the most crucial aspects of this design phase is the communication between designer and surgeon. It should be clear to both parties that it takes time to effectively work together, and a tight schedule usually cannot be met when working together for the first time. Inefficiencies lead to undesired results and a substantial increase in the time required to complete the design and manufacturing but may be minimized when the designer and the surgeon are the same person (33). | Virtual surgical planning and 3D printing: Methodology and applications in veterinary oromaxillofacial surgery |

022907e6-d5b4-aef9-2ac2-d5994f2c42e0 | Precise identification of STFBs by clinical examination is necessary with this technique, and the most important step in the localization of the small foreign bodies is a meticulous insertion of the first needle. However, the use of local anesthesia before inserting the first 23-gauge needle may lead to tumescence and loss of foreign bodies. Use of topical anesthesia or digital nerve/field blocks is therefore more appropriate before insertion of the first needle. Attempts at surgical removal were unsuccessful in the case of three small foreign bodies with a negative radiograph in the dorsum of the hand and the periorbital area using this technique. We discontinued further blind exploration and dissection in these cases to prevent any unwanted trauma to the adjacent structures. | Surgical Removal of Neglected Soft Tissue Foreign Bodies by Needle-Guided Technique |

In general, the new screws had the best results of maximum strength, which indicates that they resisted more to the forces on them before failure, which may indicate that mechanical cycling changes the capacity of the retention screws to resist to external forces and may lead to their fracture in the long term. | Analysis of Torque Maintenance and Fracture Resistance after Fatigue in Retention Screws Made of Different Metals for Screw-Retained Implant-Borne Prosthesis Joints |
0230f9af-67db-17a6-52b2-64a811a189eb | As displayed in Figure 8, for the four models in Scenario A, the stress of PDL of the adjacent lateral incisor and first premolar was mainly distributed in the cervical of the mesial and distal of the root surface and gradually decreased toward the apex. The stress of the PDL of the central incisor was concentrated on the labial and lingual cervical of the root surface. For Scenario B, the stress of PDL of the adjacent central incisor and lateral incisor was mainly distributed in the cervical of the mesial and distal surface of the root in all four models. However, the distribution of PDL stress of adjacent first premolar was different. The stress of PDL of the adjacent first premolar of Model B1 and Model B2 was mainly distributed in the cervical of the mesial and distal surface of the root, while of the Model B3 and Model B0 was mainly distributed in the cervical of the labial and lingual surface of the root. | Assessment of labially impacted canines traction mode with clear aligners vs. fixed appliance: A comparative study based on 3D finite element analysis 10.3389/fbioe.2022.1004223 |

02384c8d-cd56-221b-850b-c98388c0e547 | We encountered numerous controversies in literature about the effect of wedge insoles and knee braces in management of medial compartment knee DJD. According to study of Keating et al., there was significant pain relief in 74 of 121 knees from 85 patients with application of lateral wedges. Pain relief was most frequently obvious in mild OA in that study, but it was also documented in some patients with complete obliteration of joint space.[17] Evaluation of patients in Keating study was based on ahlback radio-logic score that was different from our criteria.[18] Besides, we did not evaluate the patients with mild OA in our study. We found significant pain relief in lateral wedge insole group compared to the control group in moderate and even severe forms of DJD, but the amount of pain reduction was less than the brace group. We did not find any similar comparison between lateral wedge and knee brace in literature. Based on Keating study, radiologic findings were significantly improved in lateral wedge group after 12 months but we did not find any significant improvement in radiologic findings, may be due to different grading system that we applied in radiologic impressions. In a recent study by Matsuno et al.,[19] 20 patients with different degrees of knee OA experienced significant pain relief besides radiographic improvement in joint alignment after 3 point knee support appliance.[11] Although they evaluated patients with all severity of medial compartment DJD, results were relatively similar to our study which 17 of 20 patients in our brace group experienced significant pain relief. We had 2 patients with severe DJD in brace group who shifted to moderate DJD radiologically after 9 months brace application. Based on above findings, it seems that both lateral wedge insoles and 3 point knee brace had significant effect on pain reduction with more profound effect with knee brace application. Three point knee support seems to have significant effect in widening of medial compartment space especially in patients with severe DJD of medial compartment. Brouwer et al. evaluated the effect of 3 point knee support on medial knee DJD and compared it with the control group.[19] They found that the overall reported walking distances were significantly longer in the brace group. It was similar to our findings for brace group but we did not find any improvement in waking distance in lateral wedge group .We also found that patients with severe forms of medial compartment DJD had more progression in walking distance compared to moderate forms. It seems that 3 point knee support had significant effect on walking distance and the effect was more profound if applied longer. Based on above findings, it seems that 3 point knee brace is superior in management of patients with moderate to severe medial compartment DJD and can even halt or reverse the process of narrowing of compartment. | Comparison the Effect of 3 Point Valgus Stress Knee Support and Lateral Wedge Insoles in Medial Compartment Knee Osteoarthritis |
023f1bc1-9bf4-9900-3623-8479f38df3f1 | The current classification of OSA is based on AHI severity only, since each OSA severity is known to have a different outcome as shown in a longitudinal cohort study. The goal of this study was to identify multiple OSA phenotypes based on various PSG features and to assess whether these PSG features were distinct from each other. It is prudent to understand the meaning of PSG features, including AHI, to identify and understand the pathophysiology of OSA. Numerous studies have reported on the importance of other PSG parameters besides AHI,however, these studies mainly focused on specific PSG parameters. There is a paucity of studies that have simultaneously analyzed and compared all PSG parameters. | Polysomnographic phenotyping of obstructive sleep apnea and its implications in mortality in Korea |
023fbccd-5dc6-501e-7e75-522951f69c45 | The most surprising finding of our study regards the displacement of unloaded teeth. The second molar was found to significantly displace in a mesial direction in the OF side, although no OF was directly applied on it. This phenomenon confirms the unreliability of choosing the diastema formed between first and second molars as a reference point for OTM assessment. Similarly, significant movement of the first and second molars in the no OF side was also found, following the same pattern described in the OF side. However, this pattern is in contradiction to that reported by previous studies in which the OTM in the no OF side was considered to be zero. A possible explanation is that the 2D measurements used in these studies may have missed displacement happening in planes other than sagittal. | Dynamic changes in tooth displacement and bone morphometry induced by orthodontic force |
023fc9b5-668a-fddd-7fd1-a7c4cc64f228 | Even though we got good results in terms of 3D localization and pose estimation but the method is still tied to multiple constraints and have some weakness. Because of the fixed number of 3D models (about 75 in the used dataset) which is a small number in comparison with the number of vehicle types in reality. For a new car that is not on our database, the model will classify it as a similar car which will affect the results of 3D model construction. Even if the vehicle is on the dataset the classification accuracy is due to the high similarity between the vehicle types especially when it is located in a faraway scene so there will be a huge loss in the feature context. Moreover, the neural network has a misrate equal to 21% which means the model will miss 1 out of 5 vehicles on each image. We have avoided heavy models to keep the running time in a reasonable range on light devices like Jetson Nano but the classification stage running time is dynamic and depends on the number of vehicles in a particular scene. We show further illustration of the proposed method in Figure 13. It shows more examples of 3D detection and segmentation using our proposed model. | 3D Vehicle Detection and Segmentation Based on EfficientNetB3 and CenterNet Residual Blocks |

0246b40b-6dae-76f4-76a8-2241fd020a0f | Our screen use questions were limited to an upper limit of more than 2 hours: given the high number of students (30%) using screens for more than 2 hours in the evening, it would have been useful to have had further detail on high duration screen users: future studies should seek details of upper limit use and we suggest asking about use of 180–240 minutes and >240 minutes. Opticians have started to offer blue light filters on glasses but we did not ask about this, and so cannot identify a subpopulation potentially protected from the adverse effects of blue light on circadian rhythms. The nature of screen based activity may add to the stimulating effect of screens, but our study did not examine content or whether screen use was related to school work or leisure activities, although telephone use is unlikely to be directly related to school work. | Do both timing and duration of screen use affect sleep patterns in adolescents? |

0249dfc9-9199-c4a2-9150-6dae99dd5416 | In terms of the total procedure time, the VG surgery required significantly shorter time than the NG surgery did. This was obviously due to the difference in the time spent on presurgical preparation, and more specific, significant differences were found in the time needed for software-aided virtual planning and surgical guide delivery after milling/3D printing. On the contrary, the time spent solely on implant placement was similar in both the VG and NG groups. Considering that the computer software for the VG surgery planning was novel to all the participants and therefore less familiar to the experiment participants when compared to the one used for the NG surgery, it could be considered that the VG surgery planning software is not difficult to learn and use even after a short period of training. A huge difference in the time needed for guide fabrication and delivery was caused by the fact that VG milling took place at chairside while NG were 3D-printed at an outsourcing dental laboratory and took 6 h to be delivered to the clinicians. These outcomes imply that the benefit of VG in terms of time effectiveness mostly lies in the convenience of using planning software and the chairside milling process. If a 3D printer is available at the clinic, NG could also be immediately delivered to the clinician; however, given that 3D printers strictly require air conditioning and ventilation equipment, it is not easy to 3D-print the surgical guide at chairside at present. | Accuracy of Dental Implant Placement by a Novel In-House Model-Free and Zero-Setup Fully Guided Surgical Template Made of a Light-Cured Composite Resin (VARO Guide®): A Comparative In Vitro Study |
024ac10e-53f9-f332-cab3-41cd014faf9b | Pseudoaneurysm of aorta is a rare condition usually seen after aortic surgeries or serious accidents. Here we report a 60 years old man without any previous medical condition who presented with non-specific symptoms and underwent different investigations for more than 1 year, until the presence of a continuous murmur raised suspicion toward his cardiovascular system. In echocardiographic and computed tomography (CT) angiographic studies a large pseudoaneurysm of aortic arch with compression effect on pulmonary artery was detected. At this stage he remembered having suffered a minor trauma 10 years ago. He finally underwent operation and his aortic wall was repaired successfully with a patch. This case highlights the importance of thorough history taking and physical examination in patients irrespective of symptoms and high index of suspicion to detect this life-threatening condition. | Pulmonary artery stenosis caused by a large aortic arch pseudoaneurysm detected 10 years after a minor trauma |
024bf3b2-59fb-02e0-3856-60c2b7505a10 | The iliac peduncle is better preserved in the left pubis. In medial view, it is broad and flat, taking up almost the entire proximal portion of the acetabulum. The peduncle is slightly expanded dorsally of the proximal blade plate which extends ventrally and curves medially to the central symphyseal surface. The posterior margin of the proximal blade is made up of the ischial peduncle which was fused to the pubic peduncle of the ischium along its entire length during life. In the left pubis the connection has been split and broken prior to fossilisation with the pubis medially and ischium laterally displaced relative to life position. The medial margin of the ischial peduncle has been split and dislodged vertically above the anterodistal margin of the pubic peduncle of the ischium.

025dc34e-bc76-2414-9b47-a00ce88bd566 | It is generally accepted that dental caries is the most common chronic childhood disease. Early childhood caries quickly involves the maxillary anterior teeth at an early age, and usually a large part of the tooth structure is lost when parents discover these caries and take the baby to a dentist. It has been a challenge to reconstruct severely damaged anterior teeth from several points of view, including difficulty in repairing and uncooperative children at an early age; therefore, tooth extraction has long been considered as a selective therapeutic approach for these cases, but many parents are dissatisfied and are asking for esthetic restorations. | Comparative evaluation of the effects of different methods of post space preparation in primary anterior teeth on the fracture resistance of tooth restorations |

025de851-ed21-a229-7d8d-f2d44ab38d35 | We have not compared our results with intramedullary splints to cortical plates in this series as we apply them in different situations. The cortical plates are fairly straightforward to apply to anterior and lateral rib fractures. In the past we had avoided fixation of posterior rib fractures as we noted an increased incidence of hardware failure in this area when we exclusively used absorbable polymer plates [4]. We then moved to titanium plates and have not noted any hardware failures since then. However, these plates are very difficult to apply under the scapula as the bicortical screws must be placed perpendicular to the plate. The use of 90 degree drills and screwdrivers will address this issue but they are not yet widely available. As such we moved to using the MatrixRib intramedullary splints for the difficult to access rib fractures (almost invariably posterior fractures) which has given us this unique opportunity to assess their performance. | An assessment of outcomes with intramedullary fixation of fractured ribs |
02631ff6-be24-4dae-9098-7e542929424c | Bilateral anterior dislocation of the shoulders is very rare. A 20-year-old man presented with bilateral anterior shoulder dislocation as a result of a diving incident. He complained of pain and restriction of movement in both shoulders with abducted and externally rotated arms. Radiographs revealed that the shoulders were dislocated. The patient was treated with closed reduction and was able to resume swimming 3 months later. To our knowledge, this is the first bilateral anterior dislocation of the shoulders during a backstroke swimming competition that was caused by this mechanism of injury. The rarity of this lesion and its uncommon mechanism prompted us to relate this observation. | Bilateral anterior dislocation of the shoulders at the start of a backstroke competition |

0264bc7c-447e-af35-2be1-d56034c474e8 | It is convenient to attach the LiDAR pose frame to the actual pose of the IMR in the k-th sampling time. The translation and rotation can be calculated through the coordinate transformation such as the conventional robotics.
