Pattern of Maxillofacial Injuries in Road traffic Accident During Covid-19

Objectives: This study aims to assess the prevalence and pattern of maxillofacial injuries presented at department of oral & maxillofacial surgery (OMFS), Mayo Hospital, Lahore, Pakistan during COVID- 19 pandemic. Determining patterns of occurrence of maxillofacial trauma and etiology can improve early diagnosis and treatment, thereby can decrease percentage of morbidity and mortality associated with these fractures. Place and duration; Sample data was collected from Department of OMFS, Mayo hospital, during January 2021 till December 2021. Methodology: (n=263) patients with confirmed diagnosis of maxillofacial trauma participated in this research. Record of all patients including sex, age, cause of road traffic accidents, radiograph, fracture site, vehicle type, use of seat belts/helmets, time to reach the hospital, and other safety devices were reviewed and evaluated. Results: There were (n=299, 57.27%) mandibular, (n=102, 19.50 %) zygomatic, (n=100, 19.10 %) maxillary, (n=12, 2.29 %) nasal, and (n=9, 1.70 %) frontal injuries. Maxillofacial trauma was more prevalent in males (87%) than in females (13%) and was commonly seen in young age groups (21-30 years). Two-wheelers (motorcycle) was the vehicle used in most of the cases reported (68.4 %) and major cause of RTA was inattentiveness to traffic rules (31.9 %). In road traffic accidents, mandible (57.27%) is the most common fractured bone, followed by Zygomatic Bone fracture. Conclusion: It is concluded that maxillofacial injuries in males (20 to 30 years) of age range were more prevalent and are observed mostly in mandibular bones. Although cases reported was less in number when compared to previous data, but pattern of fractured facial bones were more or less same.
Influence of Humidity on the Power Cycling Lifetime of SiC MOSFETs

Power cycling test (PCT) is widely used to accelerate power semiconductor device aging and assess its packaging reliability. Standard PCT only considers thermomechanical stress and neglects the effect of humidity from the environment. In this article, the power cycling lifetime of three groups [Group 1: devices under test (DUTs) preaged with 3600-h high-voltage high-humidity high-temperature reverse bias test (HV-H3TRB), Group 2: DUTs preaged with 3600-h high-temperature high-humidity storage, and Group 3: DUTs without preaging] is compared to explore the contribution of high humidity and high voltage. The results show that Groups 1 and 2 have a shorter lifetime, and the shape factor of Group 2 in Weibull analysis drops below 1, indicating that a sign of infant mortality and moisture is the root cause. After decapsulation, optical inspection, and scanning electron microscope (SEM), it is found that the bubbles form at edge termination, and the corrosion signs of moisture appear on the chip surface and bond wire in DUTs of Groups 1 and 2. This phenomenon is caused by the elements of C, O, and Si migration and deposition on the bond wire, which radically come from epoxy molding compound (EMC) and finally result in a shorter power cycling lifetime of discrete silicon carbide metal–oxide–semiconductor field-effect transistors (SiC MOSFETs).
Combining Blockchain with an E-Kanban System for Pull Leveling of an Assembly Line

Kanban system is a tool of the Just-in-time approach that many automotive companies have been adopted to improve their in-house operations. However, the traditional Kanban system has experienced some disadvantages in meeting the performance targets in terms of inventory, delivery, quality, and cost. In this paper, we propose a new combination approach of Blockchain and Electronic Kanban (E-Kanban) system to improve the traditional Kanban system for pull leveling pattern associated with the parallel information system. The proposed system is simulated to validate the feasible solutions for continuous improvement purpose. A real case of a leading automotive company in Vietnam is investigated to illustrate the proposed system.
Reynolds number and end‐wall effects on a lid‐driven cavity flow

A series of experiments has been conducted in a lid‐driven cavity of square cross section (depth=width=150 mm) for Reynolds numbers (Re, based on lid speed and cavity width) between 3200 and 10 000, and spanwise aspect ratios (SAR) between 0.25:1 and 1:1. Flow visualization using polystyrene beads and two‐dimensional laser‐Doppler anemometer (LDA) measurements have shed new light on the momentum transfer processes within the cavity. This paper focuses on the variation, with Re and SAR, of the mean and the rms velocities profiles, as well as the ∼(U’V’) profile, along the horizontal and vertical centerlines in the symmetry plane. In addition, the contribution of the large‐scale ‘‘organized structures,’’ and the high‐frequency ‘‘turbulent’’ velocity fluctuations to the total rms is examined. At low Re, the organized structures account for most of the energy contained in the flow irrespective of SAR. As the Re increases, however, so does the energy content of the higher frequency fluctuations. This trend is .
Roughness-induced receptivity to crossflow vortices on a swept wing

The generation of stationary crossflow vortices on the 45 degree swept NLF (2)-0415 airfoil at the Arizona State University Unsteady Wind Tunnel (AIAA Paper No. 96-0184, 1996; Ph.D. thesis, Arizona State University, 1996) is analyzed using a finite Reynolds-number linear receptivity theory. The receptivity theory is based on the locally-parallel flow approximation and also neglects surface curvature. The vortices are excited by a spanwise periodic array of circular roughness elements located near the attachment line. The amplitudes of the crossflow vortices at the source location are computed and compared with the experimental results. In general, the agreement is remarkably good. This suggests that the combined effect of nonparallel flow and surface curvature on the receptivity is not significant for the range of conditions considered. The linear analysis captures the receptivity variations with Reynolds number, roughness geometry, and roughness location. When the roughness height is small, the initial a.
Eating Patterns among Emergency Medical Service Providers in the United States: A Qualitative Interview Study

Emergency medical service (EMS) providers experience demanding work conditions in addition to shift work, which increases risk for nutrition related chronic disease such as metabolic syndrome, diabetes, obesity, and cardiovascular disease. The high stress, emergent, and unpredictable nature of EMS may interfere with healthy eating patterns on and off shift, however little is known about how these conditions impact dietary patterns among EMS providers. This study aimed to understand factors impacting dietary patterns through semi-structured interviews with 40 EMS providers throughout the United States. Interviews were conducted virtually via Zoom video conference. Inductive coding was used to identify themes throughout the interviews. Salient factors mentioned in the interviews included hunger, fatigue, stress, coworker influence, ambulance posting, geographical location, agency policy, and culture. Factors were grouped into 4 domains: physiological factors, psychosocial factors, physical environment, and organizational environment, represented by an adapted version of the social ecological model of health behaviors to include factors influencing eating patterns specific to EMS, which may contribute to overall health. Various barriers to healthy eating exist within EMS, and future studies should explore interventions at each level of our proposed model to improve conditions and reduce nutrition related disease risk in this essential population.
Polynomials and Primes in Generalized Arithmetic Progressions (Revised Version)

We provide upper bounds on the density of a symmetric generalized arithmetic progression lacking nonzero elements of the form h(n) for natural numbers n, or h(p) with p prime, for appropriate polynomials h with integer coefficients. The prime variant can be interpreted as a multi-dimensional, polynomial extension of Linnik's Theorem. This version is a revision of the published version. Most notably, the properness hypotheses have been removed from Theorems 2 and 3, and the numerology in Theorem 2 has been improved.
Probing the Dust Obscuration in Seyfert Galaxies using Infrared Spectroscopy. II. Implication for the Unification of Seyfert Galaxies

We report near-IR spectroscopic observations of 11 Seyfert galaxies (six Seyfert 1s, one Seyfert 1.9, and four Seyfert 2s) and additional galaxies (four LINERs, two H II, and one type 2 transition) for comparison, obtained using the Gemini twin-channel near-IR camera on the Shane 3 m telescope at Lick Observatory. With the unique design of the Gemini camera, full J and K spectra were taken simultaneously through the same slit. This produced accurate line ratios of hydrogen recombination lines over a large wavelength baseline. For the Seyfert 1s (≤1.5), the line ratios of Paβ/Brγ are not only comparable in both broad- and narrow-line regions but also consistent with case B recombination, indicating little or no reddening in both narrow- and broad-line regions. Seyfert 2 (>1.5) galaxies, however, show substantial reddening toward the narrow-line regions. We compare optical reddening data from the literature and find significant support for the dichotomy between Seyfert 1s and Seyfert 2s, at least in low-luminosity objects. Two different scenarios are explored to explain the observed difference in reddening: a difference in reddening due to an extended dusty torus under active galactic nucleus unification, and a difference due to a different grain size distribution between the two Seyfert types. We also discuss a similar potential difference found in the strength of the 9.7 μm silicate line, along with a possible correlation between the narrow-line reddening and the strength of the silicate absorption line. We also analyzed CO band head absorption features longward of 2.3 μm to look for nonstellar contamination and evidence of recent star formation activity. The CO band head in Seyfert 1s shows heavy contamination from nonstellar radiation, which is correlated with an H - K nuclear color excess. We confirm that the CO spectroscopic indices in both Seyfert types do not show evidence of recent star formation. Taking the nonstellar contamination into account, there is little evidence from the CO index for a difference in star formation rates in the nuclei of Seyfert 1s and Seyfert 2s in our low-luminosity sample.
Conference Committee Structure and Majority Party Bias in U.S. States

Abstract How representative are conference delegations in state legislative chambers? I argue that differing conference rules across state legislative chambers influence majority party control over conference delegations. With an original data set encompassing all state-level conference committees from 2005 to 2016, I compare the observed policy preferences between conference delegation and majority party medians when the majority party unilaterally appoints and when the minority party has influence over conferee selection. My results show that in state legislative chambers where the minority can influence conference appointments, delegations are ideologically biased away from the majority party. These findings underscore how majority parties are limited when minorities have procedural rights.
Upper bound analysis of plane strain rolling using a flow function and the weighted residuals method

This paper presents an innovative approach for analysing plane strain rolling. The approach is based on a solution resulting from the combination of the upper-bound method with the weighted residuals method. The upper bound method is applied to estimate the rolling torque and to model the material flow within the region of deformation between the rolls. The weighted residuals method is utilized for obtaining the distribution of stress, the roll separating force and the normal contact pressure along the surface of the rolls. Coupling between the two methods is made by using the upper bound distribution of the strain-rate in conjunction with the rate form of the Levy–Mises constitutive equations to determine an approximate distribution of the stress field by means of the weighted residuals method. The main advantage of this approach over classical upper bound solutions, is the possibility of solving stress equilibrium everywhere throughout the plastically deforming workpiece and on its surface. Such an analysis ensures a complete description of all the variables with interest to the rolling process. The validity of the proposed approach is discussed by comparing the theoretical predictions with experimental data found in the literature. Copyright © 1999 John Wiley & Sons, Ltd.
Refined shrinking target property of rotations

In this study we discuss the shrinking target property of irrational rotations. We obtain the condition of an irrational θ and monotonically increasing φ(n) such that We also consider the class of irrationals for which the limit inferior is 0 for every monotonically increasing φ(n) such that ∑n 1/(nφ(n)) diverges.
Simulations of Superluminal Radio Sources

The superluminal knots of VLBI-sources are widely believed to be shocks travelling along relativistic jets. So far only very simple quasi-one dimensional models have been used to study this phenomenon. Recent progress in numerical methods for relativistic fluid dynamics (Falle & Komissarov 1995) make it possible to carry out much more realistic simulations of such flows.
Adenylyl cyclase isoform 1 contributes to sinoatrial node automaticity via functional microdomains

Sinoatrial node (SAN) cells are the heart’s primary pacemaker. Their activity is tightly regulated by β-adrenergic receptor (β-AR) signaling. Adenylyl cyclase (AC) is a key enzyme in the β-AR pathway that catalyzes the production of cAMP. There are current gaps in our knowledge regarding the dominant AC isoforms and the specific roles of Ca2+-activated ACs in the SAN. The current study tests the hypothesis that distinct AC isoforms are preferentially expressed in the SAN and compartmentalize within microdomains to orchestrate heart rate regulation during β-AR signaling. In contrast to atrial and ventricular myocytes, SAN cells express a diverse repertoire of ACs, with ACI as the predominant Ca2+-activated isoform. Although ACI-KO (ACI–/–) mice exhibit normal cardiac systolic or diastolic function, they experience SAN dysfunction. Similarly, SAN-specific CRISPR/Cas9-mediated gene silencing of ACI results in sinus node dysfunction. Mechanistically, hyperpolarization-activated cyclic nucleotide-gated 4 (HCN4) channels form functional microdomains almost exclusively with ACI, while ryanodine receptor and L-type Ca2+ channels likely compartmentalize with ACI and other AC isoforms. In contrast, there were no significant differences in T-type Ca2+ and Na+ currents at baseline or after β-AR stimulation between WT and ACI–/– SAN cells. Due to its central characteristic feature as a Ca2+-activated isoform, ACI plays a unique role in sustaining the rise of local cAMP and heart rates during β-AR stimulation. The findings provide insights into the critical roles of the Ca2+-activated isoform of AC in sustaining SAN automaticity that is distinct from contractile cardiomyocytes.
A mAb against surface-expressed FSHR engineered to engage adaptive immunity for ovarian cancer immunotherapy

Despite advances in ovarian cancer (OC) therapy, recurrent OC remains a poor-prognosis disease. Because of the close interaction between OC cells and the tumor microenvironment (TME), it is important to develop strategies that target tumor cells and engage components of the TME. A major obstacle in the development of OC therapies is the identification of targets with expression limited to tumor surface to avoid off-target interactions. The follicle-stimulating hormone receptor (FSHR) has selective expression on ovarian granulosa cells and is expressed on 50%–70% of serous OCs. We generated mAbs targeting the external domain of FSHR using in vivo–expressed FSHR vector. By high-throughput flow analysis, we identified multiple clones and downselected D2AP11, a potent FSHR surface–targeted mAb. D2AP11 identifies important OC cell lines derived from tumors with different mutations, including BRCA1/2, and lines resistant to a wide range of therapies. We used D2AP11 to develop a bispecific T cell engager. In vitro addition of PBMCs and T cells to D2AP11-TCE induced specific and potent killing of different genetic and immune escape OC lines, with EC50s in the ng/ml range, and attenuated tumor burden in OC-challenged mouse models. These studies demonstrate the potential utility of biologics targeting FSHR for OC and perhaps other FSHR-positive cancers.
Before-and-After Study of the First Four Years of the Enhanced Recovery after Surgery (ERAS®) Programme in Older Adults Undergoing Elective Colorectal Cancer Surgery

Background: The aim of this study was to determine whether the inclusion of older patients undergoing elective colorectal cancer resection in the Enhanced Recovery After Surgery (ERAS®) programme could improve clinical outcomes during hospital admission. Methods: A before-and-after study in ≥70-year-old patients electively admitted for colorectal cancer resection was designed. In total, 213 patients were included in the ERAS® group, and 158 were included in the control group. Results: The average age was 77.9 years old (SD 5.31) and 57.14% of them were men, with a Charlson Index score of 3.42 (SD 3.32). The ERAS® group presented a lower transfusion rate of 42 (19.7%), compared to 75 (47.5%) in the control group (p < 0.001). The crude odds ratio (OR) for transfusion was 0.27 (95% CI 0.17–0.43; p < 0.001), and the adjusted odds ratio was 0.26 (95% CI 0.14–0.48; p < 0.001). The ERAS® group had a lower percentage of patients with moderate–severe malnutrition on admission, at 23.4% (37 patients) against 36.2% in the control group (42 patients) (p = 0.023), with an OR of 0.47 (95% CI 0.29–0.75; p < 0.002) and an adjusted OR of 0.48 (95% CI 0.29–0.78; p = 0.003). The number of patients who required admission to the intensive care unit (ICU) was also markedly lower: 54 from the ERAS® group (25.4%) versus 71 from the control group (44.9%) (p < 0.001). Conclusions: The inclusion of ≥70-year-old adults in the ERAS® programme resulted in a decrease in transfusions, number of erythrocyte concentrates transfused, and number of ICU admissions, along with improved nutritional status.
Spectral triples and finite summability on Cuntz-Krieger algebras

We produce a variety of odd bounded Fredholm modules and odd spectral triples on Cuntz-Krieger algebras by means of realizing these algebras as "the algebra of functions on a non-commutative space" coming from a sub shift of finite type. We show that any odd $K$-homology class can be represented by such an odd bounded Fredholm module or odd spectral triple. The odd bounded Fredholm modules that are constructed are finitely summable. The spectral triples are $\theta$-summable although their bounded transform, when constructed using the sign-function, will already on the level of analytic $K$-cycles be finitely summable bounded Fredholm modules. Using the unbounded Kasparov product, we exhibit a family of generalized spectral triples, possessing mildly unbounded commutators, whilst still giving well defined $K$-homology classes.
Using Iterated Function Systems to Reveal Biases in the Distribution of Prime Numbers

Iterated function systems (IFS) can be a surprisingly useful tool for studying structure in data. Here we present results stemming from a 2013 computational study by the author using IFS. The results include fractal patterns that reveal “repulsive” phenomena among primes in a wide range of classes, having specified arithmetic or congruence properties. Some of the phenomena shown in our computations relate to the recent, groundbreaking work of Lemke Oliver and Soundararajan on biases between consecutive primes. We do not have asymptotics to explain our results, but provide graphs, data, and detailed explanations of the phenomena. (Draft, December 18, 2016)
A Retrospective and Time Series Study of Cases of Tuberculosis: Evidence of Nnamdi Azikiwe University Teaching Hospital Nigeria

Tuberculosis (TB) is one of the leading causes of mortality in developing countries in world. It is an airborne disease spread through inhaling. This study investigated the cases of tuberculosis at Nnamdi Azikiwe University Teaching Hospital (NAUTH) Nigeria. The TB data used in this study are secondary data sourced from NAUTH tuberculosis register from January 2005 to December 2021. This study is a retrospective cohort and time series analysis of all the cases of tuberculosis diagnosed and confirmed. The forecast methods used in this study are that of Box-Jenkins approach and Holt-Winters. Out of 395070 presumptive cases, 52311 (11.7%) were diagnosed with tuberculosis, and male had the highest rate. The age group that was most affected was the group 35-44 (24.68%). 8.4% of the tuberculosis diagnosed tested positive. ARIMA (0,0,1) (2,0,1) [12] was selected as the best model, used in forecasting tuberculosis cases for the next four years. Tuberculosis cases predicted showed that for the next four years, there will be a slight decrease.
The Symptom Characteristics and the Efficacy of Combining Therapies in Inpatients with Atopic Dermatitis: A Study on Vietnamese Population

Background: Currently, biologics and targeted disease-modifying therapies were developed to provide an effective control for adult with moderate-to-severe atopic dermatitis. This study aimed to describe clinical features, stages, and severity levels of the disease as well as to evaluate the therapeutic efficacy of the combining therapies in adults with atopic dermatitis. Methods: 128 patients with atopic dermatitis diagnosis based on the Rajka and Hanifi standards at the Inpatient Department of Can Tho Dermato-Venereology Hospital from May 2018 to May 2020 were recruited in this study. The clinical characteristics were recorded. The treatment response was evaluated through the improvement of clinical presentations and the altering SCORAD score. Results: The study showed that people aged 60 and over made up the largest proportion of total investigated patients. Pruritus was the predominant symptom of atopic dermatitis. There was an association between xerosis symptom and disease severity. After two weeks of treatment, the mean of SCORAD score significantly decreased by more than halved. Additionally, 88.4% of patients showed an excellent response and there was no patient with non/poor improvement. Conclusions: Our study supports that the combination of therapeutic methods might reduce symptoms in atopic dermatitis patients, and thereby improving their quality of life.
