Authors: Loo Ke-Yan , Letchumanan Vengadesh
Published: June 2021

Malaysians are facing the biggest challenge in 2021 - the rise in COVID-19 cases and its variant of concern (VOC) strains. The scale and impact of this coronavirus disease are unimaginable, scary, and full of sorrows. Many lost their loved ones, relatives, friends, and children are becoming orphaned overnight. Now our only hope is on the available vaccines to control this deadly virus infection. When this Review article was in press, over 170 million confirmed cases with 3.5 million deaths were reported worldwide. Malaysia is dealing with spikes in the number and severity of new cases. A record toll of new cases and fatalities for consecutive weeks has pushed Malaysia's total cases to a soaring 500,000 confirmed cases with 2300 deaths – the third highest in Southeast Asia behind Indonesia and the Philippines. The healthcare system in Malaysia is currently under heavy pressure to control the disease as the number of confirmed cases is rising exponentially. A National COVID-19 Immunization Program was launched in February 2021 in the hope of providing immunity to 80% of the population in Malaysia and achieve herd immunity. This review discusses the alarming COVID-19 situation in Malaysia, the management strategies, and the vaccinations program.

Analysis of Sloshing Suppressors in Liquefied Natural Gas Carriers Tanks
Authors: Almeida Barbosa Danilo de , Piccoli Fabio Pavan , Santos Moreira Daniel dos
Published: June 2021

The sloshing problem has been studied in recent decades, as it causes damage to the container structure, caused by hydrodynamic loads. In our work, we show that it is possible to mitigate the action of the fluid on the structure. First, we applied Smoothed Particle Hydrodynamics (SPH) to perform numerical simulations involving the sloshing effect in tanks used to transport Liquefied Petroleum Gas similar to the physical experiments found in the literature. Then, we added (on the container floor) to our numerical model attenuation devices to reduce the sloshing effect. Two types of sloshing suppressors were used, where two different heights are assigned and tested. In addition, we changed the deflector's morphology, leaving it in the shape of an arrow pointing upwards. The results have shown that the baffles can be efficient mechanisms for the suppression of sloshing and that there is a strong relationship between the height of the baffles and the level of fluid concerning the tank.

Authors: Kozobrod Inna , Pyatinsky M. , Vlasenko Elena
Published: June 2021

Stock assessment of vimba population Vimba vimba (Linnaeus, 1758) in period 2015–2020 was performed by qualitative indicator method LBI (Length-Based Indicators) that allows to assess qualitative characteristics of the population and fisheries and MSY biological reference points. The indicator, qualitative approach to stock assessment was applied due to absence vimba population of stable stock-recruitment relationship (due to artificial reproduction exist), which makes impossible to apply surplus production approach to solve production equation dB/dt. LBI model was performed based on available length-weight vimba frequencies dynamics information, which allows to evaluate qualitative population characteristics and fisheries impact. Model results shows no overexploitation signals: in period 2015–2020 fisheries are carried out in maximum sustainable yield level. Indicator results according to reference points indicate no significant signals of reduction optimal length class (Lopt), small-size or large-size class. In 2016 and 2018 uncertain overexploitation of small-scale classes leads to no significant changes was underlined. In terms of biological and fisheries data lacking, LBI methods allow to perform stock assessment procedure more stable and robust then surplus or cohort approach, and output scientific advice to fisheries management.
The Cognitive Impact of Coronavirus
Authors: Muthukrishnan Hrishika
Published: June 2021

Coronavirus is a disease that leads to significant neuroinflammatory responses. There are many similarities in the way inflammation performs in several viral diseases. Specifically, the rise in pro-inflammatory cytokines occurs both in neurodegenerative diseases as well as coronavirus. These effects play a role in cognition that often results in the degeneration of cognitive processes. This degenerative process could lead to psychological illnesses such as depression and anxiety. The causal relationships and the intersection between psychological illnesses, cognition, and the neuroinflammatory response caused by coronavirus is relatively unknown, and so, a review of the current literature is conducted. This review concludes that there are many confounding variables - such as isolation and quarantine – which must be taken into account to better understand the interactions between the physiological (i.e., the neuroinflammatory response to coronavirus) and psychological factors that affect overall brain health.
Lateral Inhibition: Are two hands better than one?
Authors: Gadiraju Goutam , Andrade Daniel
Published: June 2021

This study investigated the differences in amplitude discrimination capacity between two stimuli delivered to adjacent fingertips on the same hand (contralateral delivery) and stimuli delivered to two fingers on opposite hands (bilateral delivery).  The measures were obtained in order to study the impact of lateral inhibition via interhemispheric connections on cortical centers on opposite sides of the somatosensory cortex in comparison to lateral inhibition occurring between adjacent cortical centers within the same hemisphere. Using the Cortical Metrics Brain Gauge™ device, amplitude discrimination capacity of 37 healthy subjects was assessed at several different durations, ranging from 40 to 500 msec, of vibrotactile stimulation delivered contralaterally and bilaterally. The results demonstrate a significant difference in amplitude discrimination capacity between the two conditions for stimulus duration of 200ms, with performance being better for the contralateral delivery of the stimuli than the bilateral condition for most tested durations. Task performance was roughly the same for the two conditions at the extremes of short (40ms) and long (500ms) stimulus durations. Amplitude discrimination capacity improved with longer stimulus durations in both bilateral and contralateral conditions. Though slight variation was observed at the level of each individual subject, overall, it is clear that local lateral inhibition plays a role in assessing the two stimuli delivered to the same hand that gives same-handed discrimination an advantage over two-handed discrimination. Additionally, the trends identified may be useful in guiding future experimentation that investigates clinical assessments of deficits in cortical processing that is mediated by callosal connections.
Effects of Acute Sleep Deprivation on Working Memory Capacity in Undergraduate Students
Authors: Nelabhotla Sandeep , Shanmugam Surya
Published: June 2021

Sleep is a necessary staple in our everyday lives but with advancements in society and an increase in day to day commitments it feels as though there is not enough time in the day. One of the first things to be forsaken in the hopes of maintaining a work schedule or routine is sleep. While the lack of sleep is disproportionate in most demographics, in university students in particular, a lack of sleep is a common, consistent, and necessary plague. Students can be under the impression that the effects of sleep deprivation have mostly long-term repercussions; however, prior literature has indicated that sleep deprivation impacts not just long-term consolidation but also significantly affects memory in the short-term, specifically the working memory (Xie et al. 2019; Chee et al., 2006). In this investigation, we seek to understand the effects that acute sleep deprivation has on the working memory capacity of individuals using a 2-back spatial test. A sample of convenience of upper-class undergraduate students was chosen and the participants were asked to take a specific 2-back spatial test - twice on a day that they subjectively felt as having a regular sleep schedule and twice on a day that they subjectively felt as having sleep deprivation. The team predicted that working memory 2-back task scores will be adversely affected by sleep deprivation. While there was a statistically significant difference in the working memory scores on the full sample level, this was not reflected on the individual level. This indicates that the effects of sleep deprivation are not generalizable to a full population and that they must be reviewed on a case-by-case basis. Furthermore, since greater variation was observed in the sleep deprived scores in all individuals, it implies that sleep deprivation may indirectly affect the consistency of working memory by affecting attention span and concentration.

Nonthermal Velocity in the Transition Region of Active Regions and Its Center-to-limb Variation
Authors: Ghosh Avyarthana , Tripathi Durgesh , Klimchuk James A.
Published: June 2021

We derive the nonthermal velocities (NTVs) in the transition region of an active region using the Si iv 1393.78 Å line observed by the Interface Region Imaging Spectrograph and compare them with the line-of-sight photospheric magnetic fields obtained by the Helioseismic and Magnetic Imager on board the Solar Dynamics Observatory. The active region consists of two strong field regions with opposite polarity, separated by a weak field corridor that widened as the active region evolved. The means of the NTV distributions in strong field regions (weak field corridors) range between ∼18–20 (16–18) km s−1, albeit the NTV maps show a much larger range. In addition, we identify a narrow lane in the middle of the corridor with significantly reduced NTV. The NTVs do not show a strong center-to-limb variation, albeit they show somewhat larger values near the disk center. The NTVs are well correlated with redshifts as well as line intensities. The results obtained here and those presented in our companion paper on Doppler shifts suggest two populations of plasma in the active region emitting in Si iv. The first population exists in the strong field regions and extends partway into the weak field corridor between them. We attribute this plasma to spicules heated to ∼0.1 MK (often called type II spicules). They have a range of inclinations relative to vertical. The second population exists in the center of the corridor, is relatively faint, and has smaller velocities, likely horizontal. These results provide further insights into the heating of the transition region.

au, for Class I and Flat spectrum protostars, respectively. In addition, we calculate the multiplicity statistics of the dust surrounding young stellar objects in Ophiuchus. The multiplicity fraction and companion star fraction of the combined Class I and Flats based solely on this work are 0.25 ± 0.09 and 0.33 ± 0.10, respectively, which are consistent with the values for Perseus and Orion. While we see clear differences in mass and radius between the Ophiuchus and Perseus/Orion protostellar surveys, we do not see any significant differences in the multiplicities of the various regions. We posit that there are some differences in the conditions for star formation in Ophiuchus that strongly affect disk size (and consequently disk mass), but does not affect system multiplicity, which could imply important variation in planet formation processes.

Blazars are active galactic nuclei with their relativistic jets pointing toward the observer, comprising two major subclasses, flat-spectrum radio quasars (FSRQs) and BL Lac objects. We present multiwavelength photometric and spectroscopic monitoring observations of the blazar B2 1420+32, focusing on its outbursts in 2018–2020. Multiepoch spectra show that the blazar exhibited large-scale spectral variability in both its continuum and line emission, accompanied by dramatic gamma-ray and optical variability by factors of up to 40 and 15, respectively, on week to month timescales. Over the last decade, the gamma-ray and optical fluxes increased by factors of 1500 and 100, respectively. B2 1420+32 was an FSRQ with broad emission lines in 1995. Following a series of flares starting in 2018, it transitioned between BL Lac and FSRQ states multiple times, with the emergence of a strong Fe pseudocontinuum. Two spectra also contain components that can be modeled as single-temperature blackbodies of 12,000 and 5200 K. Such a collection of “changing-look” features has never been observed previously in a blazar. We measure gamma-ray–optical and interband optical lags implying emission-region separations of less than 800 and 130 gravitational radii, respectively. Since most emission-line flux variations, except the Fe continuum, are within a factor of 2–3, the transitions between FSRQ and BL Lac classifications are mainly caused by the continuum variability. The large Fe continuum flux increase suggests the occurrence of dust sublimation releasing more Fe ions in the central engine and an energy transfer from the relativistic jet to subrelativistic emission components.
Bayesian Time-resolved Spectroscopy of Multipulse GRBs: Variations of Emission Properties among Pulses
Authors: Li Liang , Ryde Felix , Pe’er Asaf , Yu Hoi-Fung , Acuner Zeynep
Published: June 2021

Gamma-ray bursts (GRBs) are highly variable and exhibit strong spectral evolution. In particular, the emission properties vary from pulse to pulse in multipulse bursts. Here we present a time-resolved Bayesian spectral analysis of a compilation of GRB pulses observed by the Fermi/Gamma-ray Burst Monitor. The pulses are selected to have at least four time bins with a high statistical significance, which ensures that the spectral fits are well determined and spectral correlations can be established. The sample consists of 39 bursts, 117 pulses, and 1228 spectra. We confirm the general trend that pulses become softer over time, with mainly the low-energy power-law index α becoming smaller. A few exceptions to this trend exist, with the hardest pulse occurring at late times. The first pulse in a burst is clearly different from the later pulses; three-fourths of them violate the synchrotron line of death, while around half of them significantly prefer photospheric emission. These fractions decrease for subsequent pulses. We also find that in two-thirds of the pulses, the spectral parameters (α and peak energy) track the light-curve variations. This is a larger fraction compared to what is found in previous samples. In conclusion, emission compatible with the GRB photosphere is typically found close to the trigger time, while the chance of detecting synchrotron emission is greatest at late times. This allows for the coexistence of emission mechanisms at late times.

The Southern H ii Region Discovery Survey (SHRDS) is a 900 hr Australia Telescope Compact Array 4–10 GHz radio continuum and radio recombination line (RRL) survey of Galactic H ii regions and infrared-identified H ii region candidates in the southern sky. For this data release, we reprocess all previously published SHRDS data and include an additional ∼450 hr of observations. The search for new H ii regions is now complete over the range 259° < ℓ < 346°, ∣b∣ < 4° for H ii region candidates with predicted 6 GHz continuum peak brightnesses ≳30 mJy beam−1. We detect radio continuum emission toward 730 targets altogether including previously known nebulae and H ii region candidates. By averaging ∼18 RRL transitions, we detect RRL emission toward 206 previously known H ii regions and 436 H ii region candidates. Including the northern sky surveys, over the last decade the H ii Region Discovery Surveys have more than doubled the number of known Galactic H ii regions. The census of H ii regions in the Wide-field Infrared Survey Explorer (WISE) Catalog of Galactic H ii Regions is now complete for nebulae with 9 GHz continuum flux densities ≳250 mJy. We compare the RRL properties of the newly discovered SHRDS nebulae with those of all previously known H ii regions. The median RRL FWHM line width of the entire WISE Catalog H ii region population is 23.9 km s−1 and is consistent between Galactic quadrants. The observed Galactic longitude–velocity asymmetry in the population of H ii regions probably reflects underlying spiral structure in the Milky Way.

Published: June 2021

We investigate the role of small-scale dynamics in inducing large-scale transitions in the solar wind magnetic field by means of dynamical system metrics based on instantaneous fractal dimensions. By looking at the corresponding multiscale features, we observe a break in the average attractor dimension occurring at the crossover between the inertial and the kinetic/dissipative regime. Our analysis suggests that large-scale transitions are induced by small-scale dynamics through an inverse cascade mechanism driven by local correlations, while electron contributions (if any) are hidden by instrumental noise.

Published: June 2021

The diversity and distribution of freshwater molluscs is poorly studied in the Republic of Georgia, due to the scarcity of field studies during the last 50 years. Here, we present the results of the first concerted investigation of freshwater mollusc biodiversity in the Javakheti Highlands, in the southern, mountainous region of Georgia. In total, we were able to collect 22 species from 42 sampling localities, including different kinds of freshwater habitats. Amongst the 22 collected species, 12 were recorded for the first time from Javakheti. From the newly-recorded species,Bathyomphalus contortusis a new country record, whose identity is supported by 16S rRNA sequence data.
Mise en œuvre du télétravail : une relation managériale réinventée ?
Authors: Diard Caroline , Hachard Virginie
Published: June 2021

Le télétravail est un mode d’organisation du travail à distance apparu dans les années 1970, qui repose sur l’utilisation des nouvelles technologies et suppose une relation managériale renouvelée. Sa mise en œuvre interroge sur l’importance de la confiance, le contrôle et l’autonomie des télétravailleurs. Comment la relation managériale évolue-t-elle à travers ces trois dimensions lors de la mise en œuvre du télétravail ? Cette étude qualitative par entretiens semi-directifs auprès de 18 collaborateurs d’une business school explore la relation managériale par le prisme du contrat psychologique. Ce travail démontre que les managers font confiance à leurs collaborateurs et qu’ils sont satisfaits du dispositif. Il n’y a pas de contrôle spécifique, mais se développent l’autonomie du collaborateur ainsi qu’une forme d’autocontrôle.
Le modèle français d’accès à la haute fonction publique à l’épreuve de la légitimité démocratique
Authors: Gouadain Daniel
Published: June 2021

Le modèle français d’accès à la haute fonction publique, fondé sur le concours (et les connaissances scolaires), est le fruit des efforts déployés pour promouvoir l’égalité en droit, pour n’exclure a priori aucun citoyen des emplois publics. Mais, en raison des biais tenant aux disparités de fortune, culturelles, d’éducation reçue dans les familles, celle-ci, dans un contexte où la compétition est devenue très âpre, ne fait guère bon ménage avec l’égalité de fait, devenue au fil du temps une aspiration largement partagée. D’où la question : comment agir sur la composition de la haute fonction publique, sans compromettre la qualité des services qu’elle rend, comment concilier ouverture et efficacité ? Faut-il se satisfaire d’une approche ciblée sur l’ouverture sociale, faut-il envisager une approche plus globale ? Ce qui est sûr, c’est que les spécificités de notre système éducatif compliquent la tâche des réformateurs : loin de constituer un compartiment marginal de notre enseignement supérieur, comme on pourrait s’y attendre, les écoles d’accès à la haute fonction publique (Polytechnique, ENS, ENA) en constituent le couronnement.
Gaussian invariant measures and stationary solutions of 2D primitive equations
Authors: Grotto Francesco , Pappalettera Umberto
Published: June 2021

We introduce a Gaussian measure formally preserved by the 2-dimensional Primitive Equations driven by additive Gaussian noise. Under such measure the stochastic equations under consideration are singular: we propose a solution theory based on the techniques developed by Gubinelli and Jara in [15] for a hyperviscous version of the equations.

Published: June 2021

The baking conditions of walnut kernels were optimized based on different cultivars and baking methods. The influence of the different baking techniques on the chemical properties of walnut oils was determined. The results showed that acid value, peroxide value and induction period (IP) all significantly increased in the baked samples compared to the unbaked ones. The highest increase in IP was from 6 to 17 h indicating that baking can improve the oxidative stability of walnut oils and prolong their shelf-life. Several aroma components increased after baking. However, among the different baking conditions, the strongest aroma in walnut oil was observed after baking was done for 20 min with sucrose (107%) at 153 ℃. Nevertheless, baking had little effect on the fatty acid composition of walnuts.

This study aims to develop a method for the preparation of natural table olives using locally selected microorganisms and without resorting to the usual techniques which employ lye treatment and acids. The effects of parameters, such as lye treatment, inoculation with yeasts, substitution of organic acids with vinegar and/or acetic acid bacteria, and finally alternating aeration have been assessed. Four different combinations were applied to the “Picholine marocaine” olive variety using indigenous strains, namely Lactobacillus plantarum S1, Saccharomyces cerevisiae LD01 and Acetobacter pasteurianus KU710511 (CV01) isolated respectively from olive brine, Bouslikhen dates and Cactus. Two control tests, referring to traditional and industrial processes, were used as references. Microbial and physicochemical tests showed that the L3V combination (inoculated with A. pasteurianus KU710511 and L. plantarum S1 under the optimal growth conditions of the Acetic Acid Bacteria (AAB) strain with 6% NaCl) was found to be favorable for the growth of the Lactic Acid Bacteria (LAB) strain which plays the key role in olive fermentation. This result was confirmed by sensory evaluation, placing L3V at the top of the evaluated samples, surpassing the industrial one where a chemical debittering treatment with lye was used. In addition, alternating aeration served to increase the microbial biomass of both AAB and LAB strains along with Saccharomyces cerevisiae LD01 strain, but also to use lower concentration of NaCl and to reduce the deterioration of olives compared to the anaerobic fermentation process. Finally, a mixed starter containing the three strains was prepared in a 10-L Lab-fermenter from the L3V sample in order to improve it in subsequent studies. The prepared starter mixture could be suitable for use as a parental strain to prepare table olives for artisan and industrial application in Morocco.

Dance and Its Connection With the Brain and Its Functions
Authors: Lopes Maria Cristina
Published: June 2021

There is interest in neuroscience in investigating the connection between the brain and movement, which is evident with studies with athletes. More recently, studies investigating this connection emerged in dance. Based on evolutionary psychology studies, dance highlights the connection of movement, art, mind, brain, and its functions. From this background, the authors seek to understand whether dance can influence the brain, its functions, and, ultimately, human development. With Bronfenbrenner's ecological theory, they investigate dance context and skills developed by dancers. Resorting to research on the effects of dance on the brain, they noticed that dance impacts brain structure and functions and that it can aid human development.
