Authors: Canto-Canul Roberto Carlos , López-Martínez Jorge Luis , Salazar-Uitz Ricardo Rubén , Lezama-Zarraga Francisco Román
Published: April 2021

Mostly of the engineering schools in the world coincide in having high dropout rates during the first year of their new students, mainly caused by low performance in basic science subjects. Some of these academic institutions counteract this problem with the so-called “zero semester”, with face-to-face preparatory courses or, with some type of tutoring or accompaniment program for the new student; But what happens when these options are not possible to implement in the academic institution? In the Faculty of Engineering of the Autonomous University of Campeche, a leveling strategy was designed, through the implementation of a virtual propedeutic course using the academic content of the online learning platform Khan Academy. This strategy has been applied in the last two school years (2018-2019 and 2019- 2020) This project consists of a retrospective analysis of these two generations and a comparison is made with the 2017- 2018 school year, in which this strategy had not been implemented.

The Triple Product Rule is Incorrect
Authors: Stepanov* Igor
Published: April 2021

The triple product rule, also known as the cyclic
chain rule, cyclic relation, cyclical rule or Euler's chain rule,
relates the partial derivatives of three interdependent variables,
and often finds application in thermodynamics. It is shown here
that its derivation is wrong, and that this rule is not correct; hence,
the Mayer's relation and the heat capacity ratio, which describe
the difference between isobaric and isochoric heat capacities, are
also untrue. Also, the relationship linking thermal expansion and
isothermal compressibility is wrong. These results are confirmed
by many experiments and by the previous theoretical findings of
the author.

Application of Learning Approaches in Healthcare
Authors: M R Pooja
Published: April 2021

The learning approaches in healthcare would aim at
phenotyping the disease based on clinical as well as physiological
characteristics as ideally disease is defined and diagnosed by a
combination of clinical symptoms and physiologic
abnormalities.The medicine today is advanced into new realm
with the growth of applications of artificial intelligence and
machine learning in healthcare. This is important as we will not
be addressing the target population for a specific disease alone;
rather predict the likely outcome of the related disease in an
unknown population of interest with the knowledge gained. This
is of utmost focus especially with rare diseases, the data for
which are available in lower volumes. Further, prediction
outcomes available at earlier stages are important to prepare
points of care to handle disastrous outcomes resulting from the
diseases.

CHANGING PERSPECTIVES OF SUPREME COURT INTERPRETATION ON RIGHT TO PRIVACY-WITH SPECIAL CONTEXT TO AADHAAR
Authors: Mangayarkarasi R.
Published: April 2021

The term privacy is considered to be the crucial term in our society which has emerged recently and our society has witnessed this term for the past
few years. In the recent times, there has been numerous debates on the concept of right to privacy i.e. whether our constitution guarantees the right
to privacy and its reasonable restrictions, its non-recognition by some courts and this right has been recognized by the other courts. Alot of Indian
jurists has thought whether Art.21 which guarantees right to life includes right to privacy also. But there is no clear cut legal or theoretical frame
work to help us in this context. According to Clinton Rossiter privacy is a special king of independence, which can be understood as an attempt to
secure autonomy in at least a few personal and spiritual concerns, if necessary in deance of all the pressures of modern society. It is an attempt that
is to say to do more than maintain a posture of self-respecting independence toward other men; it seeks to erect an unbreakable wall of dignity and
reserve against the entire world. This paper deals with the concept of privacy and the constitutional validity of Aadhaar and Supreme court
interpretation on different case laws related to right to privacy in India.

Authors: Shefali Shefali , Juneja Saurabh , Jain Anshi , Charan Shetty Devi , Gulati Nikita
Published: April 2021

The progression and development of OPMDs is inuenced by a multitude of factors which include complex interactions between physiological,
psychological, behavioral and social factors. The persistent activation of HPA axis through tobacco usage probably impairs immune response and
has a role in progression of OPMDs. The quantication of salivary cortisol facilitates the assessment of nicotine impact on the oral mucosa and in
the progression of OPMDs. This study was undertaken to estimate the salivary cortisol levels in the OPMDs with and without habits thereby
signifying the importance of salivary cortisol in the causation of disease or as an effective biomarker for disease progression during the
pathogenetic process of the disease. Salivary cortisol levels were estimated by ELISA technique in 29 cases of differing grades of oral potentially
malignant disorders consisting of individuals with habit and lesions (Group I), 32 cases of individuals having habit without lesions (Group II) and 3
cases of individuals having lesion without habit (Group III) and 8 cases with neither habit nor lesions (Group IV). Salivary cortisol levels were
correlated within the different study groups and were analyzed using SPSS (version 20). Salivary cortisol levels were raised in group I as compared
to all other groups. Clarity in the present study has been achieved that salivary cortisol levels can be researched to the causation of the disease as an
important step forward. This study could open up newer avenues in understanding the pathogenetic mechanisms in Oral Potentially malignant
disorders.

Published: April 2021

Implication Statement

Problem-based learning (PBL) and case-based learning (CBL) often mention social identities only if this information is directly relevant to diagnosis, which can inadvertently perpetuate stereotypes in trainee learning. Using a student-developed resource entitled “Portraying Social Identities in Medical Curriculum: A Primer,” we analyzed cases for social identities, identified gaps, and proposed changes, including use of a validated name bank to reflect diversity as represented by local census data. Through this innovation, suggestions were provided to represent the social determinants of health in CBL cases. Other medical schools can use our innovation to improve the social diversity of their medical curriculums.

Views of Secondary Education Teachers in Cyprus, Regarding the Information They Receive for Pupils with Chronic Diseases in Their Classes
Authors: Stavrou Stavros  , Demetriou Loucia
Published: April 2021

In Cyprus, many pupils with chronic diseases attend public school in regular classes, managing their disease's
demands in parallel with their education. Teachers are responsible for both education and management of these pupils at school. They have to see to their safety, but they must also provide equal learning opportunities to pupils with chronic diseases. Therefore, teachers' information about each child's condition and needs is crucial for their better response to the challenge of coping with the unique needs these pupils may have at school and in the classroom. This study's purpose is an initial investigation of the quality of the information teachers receive in this context. Our methodology is qualitative. We conducted twelve interviews with secondary education teachers in Larnaca and Famagusta in Cyprus during 2019-2020. We analyzed our data by applying the Thematic Content Analysis method. Our findings indicated that teachers felt that the school's information regarding pupils with chronic diseases was either incomplete or, even worse, non-existent.

Adneksiyal Kitlelerde Preoperatif Tanı ile Postoperatif Histopatolojik Tanıların Retrospektif Karşılaştırılması
Authors: KONAC Ayse , BARUT Abdullah Yüksel
Published: April 2021

Amaç: Adneksiyal kitlesi olan vakalarda kitlenin benign-malign açısından ayrımı yapılmalıdır. Over kanseri vakalarında genellikle erken belirtilerinin olmaması nedeni ile geç tanı konulması bu hastalığın prognozunun kötü seyretmesine neden olduğu için önem taşımaktadır. Bu retrospektif çalışma, benign-malign adneksiyal kitleleri preoperatif dönemde daha iyi tanımlayabilmek, adneksiyal kitlenin malignite olasılığını daha yüksek oranda öngörmek amaçlı yapılmıştır.Yöntem: Çalışmaya retrospektif olarak 3 yıl içinde İstanbul Eğitim ve Araştırma Hastanesi Kadın Hastalıkları ve Doğum Kliniğine başvuran 570 hasta dahil edilmiştir. Bu çalışmada ultrasonografik bulgular (bilateralite, solid komponent, asit varlığı, metastaz varlığı, multilokülarite), CA125 değerleri ve hastanın yaş durumu incelenerek Malignite Risk İndeksi (RMI) değeri hesaplanmış, bu değerler postoperatif histopatolojik tanılarla karşılaştırılmıştır.Bulgular: Ultrasonografik bulgular değerlendirildiğinde bilateral ve solid alan varlığının malignite açısından anlamlı olduğu görülmüştür. Malign ve benign kitlelerde RMI değerleri arasında anlamlı fark olduğu görülmüştür (p<0,001).

We present multiband Hubble Space Telescope imaging that spans rest-frame near-ultraviolet through near-infrared wavelengths (

–1.1 μm) for 12 compact starburst galaxies at z = 0.4–0.8. These massive galaxies (

) are driving very fast outflows (

–3000 km s−1), and their light profiles are dominated by an extremely compact starburst component (half-light radius ∼ 100 pc). Our goal is to constrain the physical mechanisms responsible for launching these fast outflows by measuring the physical conditions within the central kiloparsec. Based on our stellar population analysis, the central component typically contributes ≈25% of the total stellar mass, and the central escape velocities

km s−1 are a factor of two smaller than the observed outflow velocities. This Requires physical mechanisms that can accelerate gas to speeds significantly beyond the central escape velocities, and it makes clear that these fast outflows are capable of traveling into the circumgalactic medium, and potentially beyond. We find central stellar densities

kpc−2 comparable to theoretical estimates of the Eddington limit, and we estimate

surface densities within the central kiloparsec comparable to those of compact massive galaxies at

. Relative to “red nuggets” and “blue nuggets” at

, we find significantly smaller r

e
values at a given stellar mass, which we attribute to the dominance of a young stellar component in our sample and the better physical resolution for rest-frame optical observations at

versus

. We compare to theoretical scenarios involving major mergers and violent disk instability, and we speculate that our galaxies are progenitors of power-law ellipticals in the local universe with prominent stellar cusps.
Detecting Reconnection Sites Using the Lorentz Transformations for Electromagnetic Fields
Authors: Lapenta Giovanni

We take a pragmatic definition of reconnection to find locations where a reconnection electric field causes an

×
B
drift that carries two components of the magnetic field toward their elimination. With this in mind as our target, we observe that such locations can be found using a new indicator: the velocity of the Lorentz transformation that eliminates two components of the local magnetic field. Serendipitously, the indicator naturally becomes subluminal in the close proximity of a point where two components of the magnetic field vanish and it is hard zero at the vanishing location. Everywhere else the velocity of this Lorentz frame change far exceeds the speed of light. This property can be quickly applied in practice because computing the frame change is a local operation that requires only the knowledge of the local magnetic and electric field: it can be applied in a simulation or in observational data from a field instrument. We further show that the points identified can be classified in six categories that extend the usual types of magnetic nulls to the case of 3D reconnection in the presence of a guide field. The approach is used to identify secondary electron-scale reconnection sites in a turbulent outflow from a primary reconnection site in a highly resolved massively parallel fully kinetic particle-in-cell simulation. Numerous points are found, and their detailed analysis is reported.
The Effect of the Approach to Gas Disk Gravitational Instability on the Rapid Formation of Gas Giant Planets. II. Quadrupled Spatial Resolution
Authors: Boss Alan P.
Published: April 2021

Observations support the hypothesis that gas disk gravitational instability might explain the formation of massive or wide-orbit gas giant exoplanets. The situation with regard to Jupiter-mass exoplanets orbiting within ∼20 au is more uncertain. Theoretical models yield divergent assessments often attributed to the numerical handling of the gas thermodynamics. Boss used the β cooling approximation to calculate three-dimensional hydrodynamical models of the evolution of disks with initial masses of 0.091 M
⊙ extending from 4 to 20 au around 1 M
⊙ protostars. The models considered a wide range (1–100) of β cooling parameters and started from an initial minimum Toomre stability parameter of Q

i
= 2.7 (gravitationally stable). The disks cooled down from initial outer disk temperatures of 180 K to as low as 40 K as a result of the β cooling, leading to fragmentation into dense clumps, which were then replaced by virtual protoplanets (VPs) and evolved for up to ∼500 yr. The present models test the viability of replacing dense clumps with VPs by quadrupling the spatial resolution of the grid once dense clumps form, sidestepping in most cases VP insertion. After at least ∼200 yr of evolution, the new results compare favorably with those of Boss: similar numbers of VPs and dense clumps form by the same time for the two approaches. The results imply that VP insertion can greatly speed disk instability calculations without sacrificing accuracy.
Assessing the Formation of Solid Hydrogen Objects in Starless Molecular Cloud Cores
Authors: Levine W. Garrett , Laughlin Gregory
Published: April 2021

The properties of the first-discovered interstellar object (ISO), 1I/2017 (‘Oumuamua), differ from both solar system asteroids and comets, casting doubt on a protoplanetary disk origin. In this study, we investigate the possibility that it formed with a substantial H2 ice component in the starless core of a giant molecular cloud. While interstellar solid hydrogen has yet to be detected, this constituent would explain a number of the ISO’s properties. We consider the relevant processes required to build decameter-sized, solid hydrogen bodies and assess the plausibility of growth in various size regimes. Via an energy balance argument, we find the most severe barrier to formation is the extremely low temperature required for the favorability of molecular hydrogen ice. However, if deposition occurs, we find that the turbulence within starless cores is conducive for growth into kilometer-sized bodies on sufficiently short timescales. Then, we analyze mass loss in the interstellar medium and determine the necessary size for a hydrogen object to survive a journey to the solar system as a function of ISO age. Finally, we discuss the implications if the H2 explanation is correct, and we assess the future prospects of ISO science. If hydrogen ice ISOs do exist, our hypothesized formation pathway would require a small population of porous, 100 μm dust in a starless core region that has cooled to 2.8 K via adiabatic expansion of the surrounding gas and excellent shielding from electromagnetic radiation and cosmic rays.
Introducing piXedfit: A Spectral Energy Distribution Fitting Code Designed for Resolved Sources
Authors: Abdurro’uf  , Lin Yen-Ting , Wu Po-Feng , Akiyama Masayuki
Published: April 2021

We present piXedfit, pixelized spectral energy distribution (SED) fitting, a Python package that provides tools for analyzing spatially resolved properties of galaxies using multiband imaging data alone or in combination with integral field spectroscopy (IFS) data. It has six modules that can handle all tasks in the spatially resolved SED fitting. The SED-fitting module uses the Bayesian inference technique with two kinds of posterior sampling methods: Markov Chain Monte Carlo (MCMC) and random dense sampling of parameter space (RDSPS). We test the performance of the SED-fitting module using mock SEDs of simulated galaxies from IllustrisTNG. The SED fitting with both posterior sampling methods can recover physical properties and star formation histories of the IllustrisTNG galaxies well. We further test the performance of piXedfit modules by analyzing 20 galaxies observed by the CALIFA and MaNGA surveys. The data are comprised of 12-band imaging data from the Galaxy Evolution Explorer, SDSS, 2MASS, and WISE and the IFS data from CALIFA or MaNGA. The piXedfit package can spatially match (in resolution and sampling) the imaging and IFS data. By fitting only the photometric SEDs, piXedfit can predict the spectral continuum, Dn
4000, H
α
, and H
β
well. The star formation rate derived by piXedfit is consistent with that derived from H
α
emission. The RDSPS method gives equally good fitting results as the MCMC and is much faster. As a versatile tool, piXedfit is equipped with a parallel computing module for efficient analysis of large data sets and will be made publicly available (https://github.com/aabdurrouf/piXedfit).

Authors: Viteva Ekaterina I. , Zahariev Zahari I.
Published: April 2021

Introduction: There are no reliable prospective studies on the effectiveness of LEV in Bulgarian adult patients with drug-resistant epilepsy.

Aim: The study aimed at conducting an open, prospective study on various aspects of levetiracetam (LEV) effectiveness in Bulgarian patients with drug-resistant epilepsy. 

Materials and methods: The study was performed with patients with epilepsy recruited from those attending the Department of Neurology at the University Hospital in Plovdiv, Bulgaria. The patients completed diaries about seizure frequency, severity, and adverse events. There were regular documented visits at 3 or 6 months during the first year of treatment with LEV and at 6 months afterwards, with dynamic assessment of seizure frequency, severity, adverse events, and EEG recordings. 

Results: LEV was applied as an add-on therapy in 135 patients (86 males, mean age 35 years). There was a relatively mild and persisting dynamic improvement of seizure severity, a satisfactory seizure frequency reduction in 49.6% of participants, a persisting mean seizure frequency reduction (48-58%) from 6 to 36 months of treatment and a high responder rate (53-60%) during the same period. New seizure types (focal with impaired awareness with /without evolution to bilateral tonic-clonic seizures) occurred in 4 patients. There were adverse events (dizziness, memory impairment, aggressiveness, numbness, non-epileptic seizures, depression, anxiety, speech disturbances, visual hallucinations, sleepiness, pelvic muscles weakness, confusion, sleep disturbances, loss of appetite, unstable gait, hair loss, acne, generalized rash) in 13.33% of patients.

Conclusions: LEV treatment is associated with: low and persisting improvement of seizure severity, a good and persisting improvement of seizure frequency, a possible worsening of seizure control, a possible appearance of new seizure types, a good safety and tolerability.
