PortaX Secure Automation System Using IoT – A Survey
In recent times, everything around us is automated. People are looking to make things easier and easier day by day, by reducing the work they do, but not reduce the efficiency of work. The most important thing in this technically forward world, is, what we mentioned above i.e. Automation and Security. Travel needs a lot of automation in this day and age, especially Airports. The idea of a bag can check-in by itself, and tell us where it is and deprive us of the worry of continuously checking or thinking if the luggage is okay, is just a dream for most people.

The role of gender in the decision to pursue a surgical career: A qualitative, interview-based study
Authors: Acai Anita , Mahetaji Kaushar , Reid Susan E. , Sonnadara Ranil R. 
Published: April 2020

Background: Previous literature has explored the underrepresentation of women in surgery. However, this research has often been quantitative or limited by considering only the perspectives and experiences of women at more advanced career stages. Here, we use a qualitative methodology and a sample of women and men across the career continuum to identify the role that gender plays in the decision to pursue a surgical career.
Methods: We audio-recorded and transcribed semi-structured interviews conducted with 12 women and 12 men ranging in their level of medical training from medical students to residents to staff surgeons. We used Braun and Clarke’s six-step approach to thematic analysis to analyze the data, maintaining trustworthiness and credibility by employing strategies including reflexivity and participant input.
Results: Our findings suggested that the characteristics of surgery and early exposure to the profession served as important factors in participants’ decisions to pursue a surgical career. Although not explicitly mentioned by participants, each of these areas may implicitly be gendered. Gender-based factors explicitly mentioned by participants included the surgical lifestyle and experiences with gender discrimination, including sexual harassment. These factors were perceived as challenges that disproportionately affected women and needed to be overcome when pursuing a surgical career.
Conclusions: Our findings suggest that gender is more likely to act as a barrier to a career in surgery than as a motivator, especially among women. This suggests a need for early experiences in the operating room and mentorship. Policy change promoting work-life integration and education to target gender discrimination is also recommended.

Published: April 2020

Purpose: The passive attitude of a child is a common problem as far as communication is concerned which have long been considered a central concept of social psychology. The current study investigates the causes and fear of children at early grade student. The objectives of the study were (a) to identify the reasons of the passive attitude of children at primary level; (b) to determine the elements involved in creating a passive attitude in the students at primary level; (c) to assess the causes of the passive attitude of students at primary level.
Methodology: The nature of this research was descriptive while the survey method was used to gather information. All the learners, parents, teachers of government primary schools of district Bahawalpur were the population of the study. Sample of 592 participants (teachers 125, students 366 and parents 101) was selected through using convenient sampling techniques. The questionnaire was used as a research tool for teachers, parents, and students.
Main Findings: Findings of the study demonstrate that punishment, scolding, steering, speaking loudly, beating, Burdon of homework and strictness were considered the major causes of passive attitude among students. Most of the teachers were of the view that students feel fear when the teacher scolds them and student’s hesitation level increased.
Applications: This research study fulfilled both objectives of the study. The results of the study disclosed that majority of the students; teachers and parents opined that strictness of the teachers, punishment, de-motivating attitude of teachers, Burdon of homework, curriculum, the teaching method of teacher, lack of attractive environment, home environment, crowded classrooms and lack of teachers friendly relationship with students. All these become the reasons for shy and poor confidence in the children.
Originality: In the future, this study will be helpful for the teachers and parents, how to deal with children and seeks their behaviors, As well as, this study will helpful for researchers to investigate each reason and developed the curriculum. Similarly, a policymaker can use this study to develop the rule and regulation for their institutions.

Published: April 2020

Purpose: This study was carried out to evaluate the environmental and socio-economic effects of timber harvesting as well as to identify the drivers increasing the rate of timber exploitation in Imo River Estuary, Eastern Obolo Local Government Area, Akwa Ibom state, Nigeria.
Methodology: It was conducted in five Local Government Areas (LGAs) in Eastern Obolo Local Government Area, Akwa Ibom state, Nigeria. A random sampling technique was employed to select a total of 300 respondents composed of 60 randomly selected respondents from each of the five LGAs. A structured questionnaire was used in collecting information from the respondents. Data acquired from the field was subjected to statistical and econometric analysis which included percentages, frequencies, Likert scale rating, exploratory factor analysis, and Chi-square,
Main Findings: The major finding of this study was that the major cause of timber exploitation in the study area was unemployment, absence of forest regulations, unstable government policies, lack of trained officials, and high cost of timber products. The application of the Factor Analysis Model in this study showed that loss of biodiversity, the disappearance of forest cover, damaging of immature trees and non-wood forest products are the highest environmental effects of timber exploitation in the study area, loading far higher than the stated 0.3 decision score value. Among the social effects, high cost of farm labor is the most severe of social effects in the study area, while the increased cost of wood and forest product and high cost of living ranked highest among the economic effects.
Applications: The study will be of great importance to environmental policy makers, conservationists, researchers, and Geographers in Nigeria. It will contribute significantly to knowledge build-up in relation to restoring the sanctity of threatened forests in Southern Nigeria.
Novelty/Originality: The Niger Delta region of Nigeria where this study was carried out is often synonymous with militancy and the problems of environmental pollution. However, this study veers from these already known challenges to peculiar drivers of the depleting forests in this area. The study, therefore, will contribute to the scanty literature related to the subject matter within the study area.
Audiovisual and lexical cues do not additively enhance perceptual adaptation
Authors: Ullas Shruti , Formisano Elia , Eisner Frank , Cutler Anne 
Published: April 2020

AbstractWhen listeners experience difficulty in understanding a speaker, lexical and audiovisual (or lipreading) information can be a helpful source of guidance. These two types of information embedded in speech can also guide perceptual adjustment, also known as recalibration or perceptual retuning. With retuning or recalibration, listeners can use these contextual cues to temporarily or permanently reconfigure internal representations of phoneme categories to adjust to and understand novel interlocutors more easily. These two types of perceptual learning, previously investigated in large part separately, are highly similar in allowing listeners to use speech-external information to make phoneme boundary adjustments. This study explored whether the two sources may work in conjunction to induce adaptation, thus emulating real life, in which listeners are indeed likely to encounter both types of cue together. Listeners who received combined audiovisual and lexical cues showed perceptual learning effects similar to listeners who only received audiovisual cues, while listeners who received only lexical cues showed weaker effects compared with the two other groups. The combination of cues did not lead to additive retuning or recalibration effects, suggesting that lexical and audiovisual cues operate differently with regard to how listeners use them for reshaping perceptual categories. Reaction times did not significantly differ across the three conditions, so none of the forms of adjustment were either aided or hindered by processing time differences. Mechanisms underlying these forms of perceptual learning may diverge in numerous ways despite similarities in experimental applications.

Abstract
We present intermediate-resolution spectroscopy of the optical counterpart to the black hole X-ray transient MAXI J1820+070 (=ASASSN-18ey) obtained with the OSIRIS spectrograph on the 10.4 m Gran Telescopio Canarias. The observations were performed with the source close to the quiescent state and before the onset of renewed activity in 2019 August. We make use of these data and K-type dwarf templates taken with the same instrumental configuration to measure the projected rotational velocity of the donor star. We find v
rot sin i = 84 ± 5 km s−1 (1σ), which implies a donor to the black hole mass ratio

for the case of a tidally locked and Roche-lobe filling donor star. The derived dynamical masses for the stellar components are

. The use of q, combined with estimates of the accretion disk size at the time of the optical spectroscopy, allows us to revise our previous orbital inclination constraints to 66° < i < 81°. These values lead to 95% confidence level limits on the masses of 5.73 < M
1(M
⊙) < 8.34 and 0.28 < M
2(M

Uncovered Posterolateral Rotatory Elbow Instability With Cubitus Varus Deformity Correction
Authors: Arrigoni Paolo , Kamineni Srinath 
Published: April 2020

The relationship between a longstanding cubitus varus deformity and the delayed onset of posterolateral rotatory instability has casually been reported as being caused by abnormal repetitive varus and external rotation torques with progressive failure of the lateral collateral ligament.
This article presents a case of longstanding cubitus varus in a young man, following a supracondylar fracture sustained during childhood. Posterolateral rotatory instability with lateral collateral ligament deficiency was discovered after a corrective distal humeral realignment osteotomy. The scenario was worsened by medial olecranon overgrowth that predicated symptomatic medial snapping triceps during terminal extension and secondary ulnar neuropathy.
Lateral collateral ligament reconstruction as well as an extra-articular olecranon osteotomy was performed. The ligament was reconstructed with a free graft harvested from the central portion of the distal triceps and secured with 2 bioabsorbable screws. The patient returned to work with no residual symptoms at final follow-up.
This case highlights the possibility of posterolateral rotatory instability even with no clinical evidence at presentation. It suggests the importance of laterally redirecting the triceps vector and reconstructing the lateral collateral ligament as additional procedures at the time of supracondylar osteotomy.

Published: April 2020

Studies comparing the intramedullary hip screw and the compression hip screw for fixation of intertrochanteric hip fractures have shown little difference in final functional outcome. However, the characteristics of the rehabilitation process for these implants have not been analyzed. This study used the Functional Independence Measure (FIM Instrument; Uniform Data System for Medical Rehabilitation, Amherst, New York) to better characterize the subtle differences of the perioperative, clinical, and rehabilitative treatment of intertrochanteric fractures using the intramedullary hip screw or compression hip screw.
Ninety-four patients with isolated intertrochanteric fractures were treated with either an intramedullary hip screw or compression hip screw at our institution. To reduce technical bias, only experienced surgeons were used and patient allocation was surgeon based (eg, surgeons consistently used the same preferred implant). We evaluated the following FIM categories: bed mobility, bed transfer, gait independence, and distance ambulated. Length of stay and level of discharge disposition were also evaluated.

The intramedullary hip screw group performed better with bed transfers (
P
<.05), demonstrated better ambulatory ability at discharge (
P
<.06), and had an increased gait distance at discharge (
P
<.07). Skin-to-skin operative time and estimated blood loss was significantly less for the intramedullary hip screw group. Length of hospital stay and discharge disposition failed to reach statistical significance.

Our study found that when using the FIM scores, some differences were noted in the acute rehabilitation characteristics in patients between the intramedullary hip screw and the compression hip screw. These findings may have medical and social importance as well as significant economic implications. Further study with a larger sample size and more stringent study design are recommended.

Authors: Austin Luke , Mathur Moses , Simpson Elizabeth , Lazarus Mark 
Published: April 2020

This study elucidated the rate and type of complications after two-incision distal biceps tendon repairs. The study examined the predictive value of patient variables in identifying patients at risk for specific complications, and lastly, it evaluated the placement of the dorsal incision as a predictor of proximal radioulnar synostosis after two-incision repair.
A single surgeon's series of 84 consecutive patients who had distal biceps tendon repair using the two-incision, modified Boyd and Anderson approach were retrospectively reviewed. A rate and complication profile was developed. Variable analysis was performed on the study. A second series, a referral group diagnosed with radioulnar synostosis after two-incision biceps repair, was also reviewed for comparison. Measurement of nearest distance of dorsal incision to the ulnar crest was made and compared between the study group and the referral group.
Six different types of complications occurred with a total of 20 complications. Three complications required repeat operation. No patient variables were found to be statistically significant predictors of complications. The proximity of the dorsal incision to the ulnar crest correlated with the development of radioulnar synostosis.
Two-incision distal biceps tendon repair has a low rate of major complications. Patient specific variables do not appear to be associated with the rate or type of complications. Placement of the dorsal incision on the ulnar crest may be associated with the development of radioulnar synostosis.
Fate of Mu Receptors During Rat Skeletogenesis

Published: April 2020

Studies have intimated a role for endogenous opioids in skeletal ontogeny. We hypothesized that this role may be confined to the perinatal period. We, therefore, examined both fetal and postnatal rat long bones to determine the pattern, if any, of mu receptor expression.
Perfused long bones and brains were harvested from 3 to 4 each of near-term fetuses, 3- to 4-week-old neonates, and 6-week-old juveniles. Tissues were decalcified, embedded, sectioned, quenched of peroxidase, and then blocked. Sections were incubated overnight with either rabbit antirat mu receptor IgG or naïve rabbit IgG (control) at 4°C. The next day, sections were washed, blocked again, and incubated with biotinlabeled secondary antibody, streptavidin-peroxidase conjugate, and a chromogen substrate with intervening wash steps. Slides were counterstained with hematoxylin and coverslipped. Digital photomicrographs were then imported into an image analysis program and the percent area of stained cortical and trabecular bone quantified.
Mu receptor expression decreased significantly with age. Approximately 25% of the area of fetal long bones stained positively, including the endosteum, periosteum, and the growth plate. Little or no nonspecific staining occurred. Staining in neonatal tissue was diminished to <11% of the area and involved areas of apparent remodeling; chondrocytes in the growth plates failed to stain. Finally, juvenile bone evidenced staining approaching background levels produced by control slides (approximately 2%).
Mu receptors are abundant in developing rat long bones during fetal development but become progressively less abundant postnatally. This infers a role for endogenous opioids during skeletal ontogeny.
The combined effect of two westerly jet waveguides on heavy haze in the North China Plain in November and December 2015
Authors: An Xiadong , Sheng Lifang , Liu Qian , Li Chun , Gao Yang , Li Jianping 
Published: April 2020

Abstract. Severe haze occurred in the North China Plain (NCP) from November
to December 2015, with a wide spatial range and long duration. In this
paper, the combined effect of the anomalous stationary Rossby waves within
two westerly jet waveguides on this haze event in the NCP is investigated
based on observational visibility data and NCEP/NCAR reanalysis data. The
results show that circulation anomalies in Eurasia caused by the propagation
of anomalous stationary Rossby wave energy along two waveguides within the
westerly jet originating from the Mediterranean were responsible for haze
formation in the NCP. The Rossby waves propagated eastward along the
subtropical westerly jet and the polar front jet, causing an anomalous
anticyclone over the Sea of Japan and anticyclonic wind shear at 850 hPa
over the NCP, which enhanced the anomalous descent in the middle and lower
troposphere and subsequently resulted in a stable lower atmosphere.
Furthermore, the anomalous stationary Rossby waves propagating along the
polar front jet weakened the East Asia trough and Ural ridge and
strengthened the anomalous southerly wind at 850 hPa over the coastal areas
of eastern China, decelerating the East Asia winter monsoon. The above
meteorological conditions modulated haze accumulation in November and
December 2015. Meanwhile, continuous rainfall related to ascending motion
due to Rossby wave propagation along the waveguide provided by the
subtropical westerly jet occurred in a large area of southern China. The
associated latent heat release acted as a heat source, intensifying the
ascending motion over southern China so that the descending motion over the
NCP was strengthened, favoring the maintenance of severe haze. This study
elucidates the formation and maintenance mechanism of large-scale haze in
the NCP in late fall and boreal winter.

RNA sequencing of CD4 T-cells reveals the relationships between lncRNA-mRNA co-expression in elite controller vs. HIV-positive infected patients
Authors: Chen Chaoyu , Lu Xiangyun , Wu Nanping 
Published: April 2020

Background
Elite controller refers to a patient with human immunodeficiency virus infection with an undetected viral load in the absence of highly active antiretroviral therapy. Studies on gene expression and regulation in these individuals are limited but significant, and have helped researchers and clinicians to understand the interrelationships between HIV and its host.

Methods
We collected CD4 T-cell samples from two elite controllers (ECs), two HIV-positive infected patients (HPs), and two healthy controls (HCs) to perform second-generation transcriptome sequencing. Using the Cufflinks software, we calculated the Fragments Per Kilobase of transcript per Million fragments mapped (FPKM) and identified differentially expressed (DE) mRNAs and long non-coding RNAs (lncRNAs), with corrected P value < 0.05 (based on a false discovery rate (FDR) < 0.05). We then constructed a protein-protein interaction network using cytoHubba and a long non-coding RNA-mRNA co-expression network based on the Pearson correlation coefficient.

Results
In total, 1109 linear correlations of DE lncRNAs targeting DE mRNAs were found and several interesting interactions were identified as being associated with viral infections and immune responses within the networks based on these correlations. Among these lncRNA-mRNA relationships, hub mRNAs including HDAC6, MAPK8, MAPK9, ATM and their corresponding annotated co-expressed lncRNAs presented strong correlations with the MAPK-NF-kappa B pathway, which plays a role in the reactivation and replication of the virus.

Conclusions
Using RNA-sequencing, we systematically analyzed the expression profiles of lncRNAs and mRNAs from CD4+ T cells from ECs, HPs, and HCs, and constructed a co-expression network based on the relationships among DE transcripts and database annotations. This was the first study to examine gene transcription in elite controllers and to study their functional relationships. Our results provide a reference for subsequent functional verification at the molecular or cellular level.
