Movement Patterns During a Jump-Landing Task in Athletes After Sport-Related Concussion and Healthy Control Individuals
Authors: Lee Bobby Jean , Blueitt Damond , Hannon Joseph , Goto Shiho , Garrison Craig 
Published: February 2021

Context
A relationship between a history of sport-related concussion (SRC) and lower extremity injury has been well established in the literature.

Objective
To determine if biomechanical differences existed during a double-limb jump landing between athletes who had been released to return to play after SRC and healthy matched control individuals.

Design
Cross-sectional study.

Setting
Health system–based outpatient sports medicine center.

Patients or Other Participants
A total of 21 participants with SRC (age = 15.38 ± 1.77 years, height = 169.23 ± 8.59 cm, mass = 63.43 ± 7.39 kg, time since release to return to sport after SRC = 16.33 ± 12.7 days) were compared with 21 age-, sex-, and activity-matched healthy participants serving as controls (age = 15.36 ± 1.73 years, height = 169.92 ± 11.1 cm, mass = 65.62 ± 12.08 kg).

Main Outcome Measure(s)
Biomechanical performance during the double-limb jump landing was assessed using a motion-capture system and force plates. The average of 3 consecutive trials was used to calculate lower extremity joint kinetics and kinematics. The variables of interest were internal knee-extension moment, internal varus moment, and total sagittal-plane knee displacement for the dominant and nondominant limbs. Independent t tests were performed to examine the differences between SRC and control groups for the variables of interest.

Results
No differences existed between groups for the descriptive data. The SRC group demonstrated greater internal knee-extension moments in the dominant (−0.028 ± 0.009 Nm/kg, P = .003) and nondominant (−0.018 ± 0.007, P = .02) limbs. The SRC group also exhibited greater internal varus moments in the dominant (0.012 ± 0.004 Nm/kg, P = .005) and nondominant (0.010 ± 0.003, P = .005) limbs. For sagittal-plane knee displacement, the SRC group displayed less knee-flexion displacement in the dominant (−12.56 ± 4.67°, P = .01) but not the nondominant (−8.30 ± 4.91°, P = .10) limb.

Conclusions
Athletes who had been released for return to sport after SRC landed with greater knee valgus than healthy matched control participants.
The density of states of 1D random band matrices via a supersymmetric transfer operator
Authors: Disertori Margherita , Lohmann Martin , Sodin Sasha 
Published: February 2021

Recently,M. and T. Shcherbina proved a pointwise semicircle law for the density of states of one-dimensional Gaussian band matrices of large bandwidth. The main step of their proof is a new method to study the spectral properties of non-self-adjoint operators in the semiclassical regime. The method is applied to a transfer operator constructed from the supersymmetric integral representation for the density of states.
We present a simpler proof of a slightly upgraded version of the semicircle law, which requires only standard semiclassical arguments and some peculiar elementary computations. The simplification is due to the use of supersymmetry, which manifests itself in the commutation between the transfer operator and a family of transformations of superspace, and was applied earlier in the context of band matrices by Constantinescu. Other versions of this supersymmetry have been a crucial ingredient in the study of the localization–delocalization transition by theoretical physicists.
Case Report: Severe COVID-19 and Dengue in an Indonesian Infant

Published: February 2021

ABSTRACTWe report a case of a 10-month infant with dual severe infection of COVID-19 and dengue fever who was admitted to the hospital with an influenza-like illness. The patient experienced severe conditions of COVID-19 and dengue fever with shock followed by disseminated intravascular coagulation. The standard of COVID-19 care was given coupled with fluid resuscitation and blood transfusion. The pitfalls of this case are how to differentiate the clinical manifestation of dengue fever in a patient with confirmed COVID-19; the difficulty to monitor the dengue course of illness of the patient in the COVID-19 isolation room; and to differentiate the severe dengue from the multisystem inflammatory syndrome-C when the patient was in critical condition. The infant recovered without sequale, but the management of new probable cases must be improved more thoroughly, especially during dengue peak period in tropical and developing countries such as Indonesia.

Authors: Adeniyi Samuel , Kuku Olaotan 
Published: February 2021

There had been mixed observations about the ability and achievement of learners with hearing impairment. However, there are consensus that impactful teaching effort could aid in stimulating innovative approaches in teaching and learning of mathematics of learners particularly among learners with hearing impairment. This study seeks to appraise the impact of gamification and experiential learning on achievement in mathematics among learners with hearing impairment in Lagos State, Nigeria. The study population comprised learners with hearing impairment in Lagos State. Purposive and simple random sampling were used to select sample of 24 learners. The research design used was quasi-experimental pretest posttest traditional method group. Mathematics Knowledge Check (MKC) was used to collect data and the data collected were analyzed using mean, standard deviation, mean difference and analysis of covariance (ANCOVA). The hypotheses were tested at 0.05 level of significance. The study found out that achievement in Mathematics differs as a result of exposing learners with hearing impairment to gamification and experiential learning methods of instruction. Besides, the study observed that the two interventions benefit were of benefit to male and female learners with hearing impairment. The employment of gamification and experiential learning instructional strategy was recommended for mathematics lessons of learners with hearing impairment.

Published: February 2021

It is natural for students to expect appropriate behaviours from their teachers. Not only students but also every human being appreciates care from surrounding individuals. Within the classroom, students can feel less motivated to take part in the learning of the given course with the teacher who has offensive behaviours. The purpose of this study was to explore students’ reflections about what they consider to be appreciable behaviors of mathematics teachers, for students to be motivated to learn. The study also intended to find out whether there is a link between teachers' behaviours and students' career development. A total number of 53 students comprised of 16 primary pupils, 26 secondary students, and 11 graduate students participated in this study. Purposive, inconvenient, and systematic sampling methods were used to collect data. The findings showed that teachers’ behaviours can influence learners’ interest to learn mathematics. However, the study showed that there is no link between mathematics teachers' behaviours and learners' career development. Therefore, teachers are advised to be approachable, responsive, and behave in a way that motivates students to learn mathematics.

Para isso, em um primeiro momento, discuto a emergência da cena preta LGBT de São Paulo a partir dos discursos em torno da relação entre arte e política sobre um conjunto de estéticas, lugares e sujeitos identificados como “geração tombamento”, e o enquadramento de uma cena de festas engajadas com redes, estética e códigos próprios. Num segundo momento trago algumas notas etnográficas do trabalho de campo realizado em um baile funk LGBT e periférico onde se produzem ambientes em que sujeitos negros LGBT podem se afirmar, desajar e se sentir desejados.
NEURAL NETWORKS IN FINANCE: A DESCRIPTIVE SYSTEMATIC REVIEW
Authors: Riyazahmed K. 
Published: February 2021

Traditional statistical methods pose challenges in data analysis due to irregularity in the financial data. To improve accuracy, financial researchers use machine learning architectures for the past two decades. Neural Networks (NN) are a widely used architecture in financial research. Despite the wider usage, NN application in finance is yet to be well defined. Hence, this descriptive study classifies and examines the NN application in finance into four broad categories i.e., investment prediction, credit evaluation, financial distress, and other financial applications. Likewise, the review classifies the NN methods used under each category into standard, optimized and hybrid NN. Further, accuracy measures used by the research work widely differ, in turn, pose challenges for comparison of a NN under each category and reduces the scope of formalizing a theory to choose optimum network model under each category.

Published: February 2021

Ulcer disease has caused significant economic losses in the culture of snakehead fish Ophiocephalus argus (Cantor). Information available on Citrobacter freundii as a possible causal agent for this disease is scarce. In this study, a virulent strain, temporarily named GB1, was isolated from diseased snakehead fish suffering from ulcer disease and was identified as C. freundii through molecular and phenotypic methods. A phylogenetic tree was constructed to examine isolate GB1 and compare it to other known isolates. In addition, isolate GB1 has developed resistance to aminoglycosides, tetracyclines, and sulfonamides drugs for veterinary use in aquaculture as revealed when screened against a range of common antibiotics. To the best of our knowledge, this is the first report of ulcer disease caused by C. freundii in snakehead fish. Published

Published: February 2021

Worldwide metastasis of novel coronavirus COVID-19 has caused immense alterations among every walk of human existence and social interaction(1). Education and training sector being as vulnerable to these adjustments as any other domain(2). Owing to its extremely infectious nature, the COVID-19 pandemic enforced the closure of training institutes globally. All the traditional classroom training were restricted as an instant consequence, to achieve the norms of social distancing which can perhaps aid in obliterating the infection curve and lessen the resultant fatalities(3).
Educational institutions in India predominantly bank on traditional methods of training, utilizing conventional setup of in-person training and lectures in a teaching space. While over the years, there is a marked shift towards blended learning, still most of the academic institutes are guided by the existing orthodox learning methodologies. An unexpected outbreak of the Covid-19 pandemic caused by Corona Virus (SARS-CoV-2) shuddered the entire world (4). This complete shutdown kind of circumstances has tested the education system globally and coerced the educators to shift to digital platforms and online modules almost instantaneously. Academic institutions were required to shift from their traditional pedagogical approach to online teaching-learning. The article recognises the possible barriers to swiftly shift from traditional methods of learning towards e-learning among adult professionals through analysing the limitations faced by the authors while converting and conducting traditional trainings into e-trainings at The National Cold Chain and Vaccine Management Resource Centre (NCCVMRC-NIHFW), New Delhi. This article also put some light on methodologies that could assist academic institutions in dealing with challenges associated with shifting towards e-learning.

Authors: Carlos-Hiceta Angeli C. , Reyes-Quintos Maria Rina T. 
Published: February 2021

Objective. The purpose of this study is to identify the incidence rate of 'refer' result in neonates born to diabetic mothers and to determine the association of maternal diabetes and the initial 'refer' result.
Methods. This was a retrospective cross-sectional study which included neonates who had hearing screening test using transient-evoked otoacoustic emissions test (TEOAE) on both ears at the Philippine General Hospital Ear unit during three weeks. We obtained the demographic characteristics, presence/absence of maternal diabetes, and OAE results.
Results. Among the 150 neonates, ten were born to diabetic mothers, with an age range of 2-8 days old. Forty percent of neonates of diabetic mothers had an initial 'refer' result compared with 7.9% of nondiabetic mothers' neonates. After logistic regression analysis, there is a significant association between maternal diabetes and initial 'refer' result in OAE with a p-value <0.05. If the mother is diagnosed with diabetes (gestational/pre-gestational), the odds of having an initial 'refer' result in the hearing screening is 2x higher. The odds can range from 2-43 times.
Conclusion. The incidence rate of an initial 'refer' result in neonates of diabetic mothers is 40%. There is a significant association between maternal diabetes and the initial 'refer' result in the OAE test.

Published: February 2021

A study was conducted to determine the effects of cutting frequency and fertilizer-N rates on growth and production of guinea grass (Panicum maximum Jacq). The experiment was conducted in Nsukka, Nigeria. Treatments comprised four levels of fertilizer N (0, 150, 300 and 450 kg N ha ') and four cutting intervals (3, 6, 9 and 12 weekly intervals). Plant height, tiller number and herbage dry matter yields were significantly increased by 6%, 44% and 53%, respectively, during the establishment year when fertilizer-Nrate was increased from 0 to 450 kg N ha'. The extent of weed cover was significantly (P < 0.05) reduced by 33% in 2000 when fertilizer-N rate was increased from 0 to 450 kg N ha'. Increase in interval between cuts from 3 to 12 weeks significantly (P < 0.05) increased plant height in all the years. Plant height was increased (P < 0.05) by 28% 34% and 28% in 2001, 2002 and 2004, respectively, when fertilizer N was increased from 0 to 450 kg ha'. Application of Nat 450 kg ha produced similar plant heights in 2001 with the 300 kg N ha' but differed from the 150 kg N ha'. Increase in nitrogen application progressively increased (P<0.05) plant height in 2002 and 2004.
