STELLAR EVOLUTION AND THEIR ASTRONOMICAL OBSERVATIONS
Authors: Pandey A.
Published: November 2021

There is a hugh number of stars (~ few hundred billions) of different ages, sizes and masses in our galaxy, the Milky Way, and billions of other galaxies in the Universe. It was extremely challenging for astronomers to classify them into different groups to understand their properties precisely. In general, stars remains in the main sequence phases in the HR diagram for the largest fraction of its life time because it maintains hydro-static equilibrium during this phase. Stars of diverse mass range pass through different evolutionary phases. Some of these end their lives as catastrophic explosions not understood well so far and have a great potential to understand the overall evolution process of stars and in turn evolution of the Universe. Ground and space-based multi-wavelength observations of these objects are crucial to understand them in terms of laws of physics. In near future, advancement of technology demands extensive use of artificial intelligence, neural networks, robotics to understand astronomical observations in a better way.

Published: November 2021

The Royal Observatory of the Spanish Navy (ROA) is specialist in space geodesy since the beginning of the space race. In 1975 a laser station was installed at ROA in collaboration with the French CERGA (Centre de Recherches en Géodynamique et Astrométrie). Since 1980, ROA has operated that station by their own. This equipment routinely tracks artificial satellites equipped with retro-reﬂectors. In 2014 ROA opened a new field of research: tracking of artificial satellites currently not active and equipped with retroreﬂectors. This new area was a challenge given the poor orbital accuracies that are available for these objects as they were not tracked on a routine basis. This served as an approach to our final goal: to strictly monitor space debris, this is, any type of uncontrolled man-made orbiting objects. To fulfill the objective, since 2017, we made significant changes to our laser installation. The most important was the replacement of the old laser bench with two new ones. One transmitting 500 mW-pulses, and another laser bench with 25 W transmission power. The study for the installation of the later laser was financed through European Union (EU) H2020 fundings and granted by the Spanish Centre for Industrial Technological Development (CDTI). Although it allows the tracking of collaborative objects, it is ideal for tracking non-collaborative too. Tracking activities begin in November 2017. From then onward, non-collaborative objects are monitored on a regular basis. This work shows the modifications already made, and the results obtained until 2019.
AUTOMATING THE ALERT RESPONSE OF THE NU TRANSIENT TELESCOPE AT ASSY-TURGEN ASTROPHYSICAL OBSERVATORY (NUTTELA-TAO)
Authors: Maksut Z. , Grossan B.
Published: November 2021

Our project aims to identify the physical nature of gamma-ray burst (GRB) emission via measurement of the optical spectral shape of this emission during the prompt phase, usually lasting only 60 sec. These measurements require a fast-moving optical telescope and instrumentation to respond autonomously to real-time GRB alerts. The Nazarbayev University Transient Telescope at AssyTurgen Astrophysical Observatory (NUTTelA-TAO) has a 0.7 m aperture, and can point anywhere above the local horizon in 8 seconds. We receive GRB Alerts via internet socket connection to the Gamma Coordinates Network (GCN) at the telescope site. We measure the GRB prompt optical emission with the Burst Simultaneous Three-Channel Imager (BSTI), which incorporates 3 EMCCD cameras, at Sloan g', r', and i' bands, for simultaneous high time-resolution imaging as fast as a few hundred millisecond per frame. We describe our automated control system software, including the overall control algorithm, control of the telescope, control and actuation systems for the enclosure roof, control of the instrument, and inputs from weather and other sensors. The software system is based on the GNU data language (GDL) in a Linux environment, selected for ease of writing and de-bugging software, familiarity to the project scientists, and image analysis capabilities. We give system performance results obtained during the early commissioning period.

The Cubesats Applied for MEasuring and LOcalising Transients (CAMELOT) initiative proposes to deploy a ﬂeet of 3U nanosatellites in order to localise GRBs with all-sky coverage. The operation is based on measuring the time delay of the event trigger between satellites that are otherwise uniformly distributed around the Earth in low-Earth orbit (between 500 - 600 km of altitude). In this design, caesium-iodide crystals interact with soft gamma radiation by emitting optical photons. Utilization of this effect, each member of the ﬂeet is equipped with four of such scintillators and the emitted photons are detected by multi-pixel photon counters (MPPCs). Precise timing is crucial for this concept, the timestamping of the events and the synchronisation is provided by GPS. In order to demonstrate the feasibility of the CAMELOT concept, a single-unit CubeSat, named "GRBAlpha" is currently being developed. GRBAlpha is equipped with a single block of scintillator but the other subsystems are all the same as it will be on the CAMELOT units. We describe this single-unit platform system, focusing on the model versions suitable for high-altitude stratospheric balloon ﬂights. This model has a standardized layout (including pin-out configuration, signalling and bus communication) and compatible with significant proportion of CubeSat system vendors. This system of ours is also capable of hosting multiple payloads at the same time, optimizing the utilization of balloon experiments.

Published: November 2021

We explore the study of energetic transients including core-collapse supernovae using various publicly available analysis tools like MESA & SNEC, MOSFiT and SNCOSMO. We used MESA to evolve a star having zero age main sequence mass (Mzams) of 24 M⊙ until the onset of core-collapse. Then we exploded this model using openly available explosion codes, STELLA & SNEC and obatined various observable parameters such as bolometric luminosity and photospheric velocities etc. We also used MOSFiT to model the light curve of a type Ic supernova, SN1999ex and obtained various physical parameters. SNCOSMO is used for template fitting of various supernovae by varying various parameters such as red shift, dust map, stretch factor of light curve, explosion epoch of supernova etc.

Postharvest Treatment of Chinese Kale (Brassica oleracea var. alboglabra) by Pulse Light to Removal of Microbial Load, Pesticide Residue and Integrity of Physicochemical Quality and Phytochemical Constituent
Authors: Minh Nguyen Phuoc
Published: November 2021

Existence of microorganisms, pesticide residue on fresh vegetables has a potential hazard to human health. The demand for safe green Chinese kale (Brassica oleracea var. alboglabra) has increased recently. Chinese kale is a healthy botanical attached to the Brassicaceae class. It contains numerous nutritional and phytochemical constituents beneficial for human health. Besides health benefits, this green vegetable also poses food safety concerns due to pathogen and pesticide residue during cultivation. Non-thermal physical technology like pulsed light (PL) will be a promising alternative to eradicate microbial and pesticide residue while preserving the best physicochemical properties and phytochemical components. This research evaluated the influence of different pulsed light intensities (1.2-10.8 J/cm2) on the removal of microbial load and pesticide residue as well as weight attrition, texture hardness, dry matter, vitamin C, total phenolic content in the treated Chinese kale. Results showed that pulsed light intensity 8.4 J/cm2 was appropriate to completely eliminate pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, Salmonella; pesticide substances such as carbendazim, abamectin, cypermethrin, chlorpyrifos ethyl, mancozeb. At pulsed light intensity 8.4 J/cm2, weight attrition in the treated sample was lower than weight attrition in the untreated; meanwhile textural hardness, dry matter, ascorbic acid and total phenolic content remained higher in the treated sample compared to the untreated. The results reveals that the pulsed light technique should be applied as a promising decontamination approach for removal of the pathogen as well as pesticide residue with minor impact on physicochemical properties and phytochemical constituents.

Controlling the Mitigating Impacts of Communication Delay on Load Frequency Control with an Adaptive Method
Authors: Prasanna Velpula Lakshmi
Published: November 2021

Abstract: Load Frequency Control is one of the most essential frequency management technologies in modern power systems (LFC). When employing LFC over a vast region, communication latency is unavoidable. A delay might not only affect system performance but also cause system instability. An alternate design strategy for constructing delay compensators for LFC in one or more control areas utilising an AFPI controller and ANFIS is proposed in this paper. For one-area LFC, a sufficient and required condition for designing a delay compensator is described. It is demonstrated that for multi-area LFC with Area Control Errors (ACEs), each control area can have its own delay controller designed as if it were a one-area system if the index of coupling among the areas is less than the small gain theorem's threshold value. The effectiveness of the proposed technique is validated by simulation experiments on LFCs with communication delays in one and multiple interconnected areas with and without time variable delays.

The foot is a complex structure of more than 26 bones, 30 joints, numerous tendons, ligaments, and muscles responsible for our ability to stand upright, supporting the entire body's weight, and providing the basis for the bipedal gait mechanism. Ankle joint is the commonest joint injured in the musculoskeletal injuries without adequate rehabilitation function can be severely impaired, but access to the physiotherapy rehabilitation service can be limited due to geographical remoteness and inadequate or absence of services in the rural areas. Wound complications have been reported to occur in 1.4% to18.8% of patient with ankle injuries. In 2005, nearly 12 per cent of all ER visits or 13.8 million visits for laceration care were reported. Depending on the location and severity of the injury, lacerations can be managed in the ambulatory environment as well. Foot and ankle conditions are common in older adults. The commonest ankle injury is ankle sprain, ankle instability these type on injury are more commonly seen in sports person. Ankle Laceration is a debilitation condition which leads to lack of mobility and if not treated properly may lead to wound infection. As the tendon in the ankle region are more superficial there is high chances of tendon or nerve injury in the cases of ankle laceration. Here presenting a 19 year old girl with a laceration injury on the left ankle while mowing the lawn, she has undergone grafting and since then on physical therapy management.

Authors: Patil Deepali
Published: November 2021

Patient management and intervention practices are a crucial component of patient treatment in the hospitals. Increase in inpatient mobilization to improve patient treatment raises a physiotherapist’s physical demands and therefore risk of injury. With the context of a patient mobilization program, better work procedures and decrease in physiotherapist’s injuries while working, SPH program was incorporated. The purpose of this study is to assess the impact of the SPH program and mobilization in the context of efforts to improve health care quality and patient safety, as well as the safety of physical therapists. There will be 2 groups, intervention (SPH) and comparison (no-SPH) each group will consist of 30 patients. The intervention group will be consisting the patients admitted in rehabilitation unit for the first three months of the research and the comparison group will consist the patients admitted in rehabilitation unit in the last 3 months of the research. Intervention group will undergo rehabilitation with SPH program which will include equipment like lifts based on ceiling and floors, sit to stand supports, motorized hospital beds and ambulation aids. In this study we found that the SPH program did not impede rehabilitation but also somewhat sped up the recovery process. Patients who had an SPH program during rehabilitation showed similar but better outcomes than those who did not.

Political Trust and Values of Loyal and Oppositional Youth in the Exclave Region of Russia
Authors: Shchekoturov Aleksandr V.
Published: November 2021

The study determines the level of trust in public and political institutions among the loyal and oppositional youth of the Kaliningrad region, as well as their attitudes towards materialistic and post-materialistic values. The study is based on R. Ingleharts theory of value and the understanding of trust as described in the works of P. Sztompka and A. Giddens. The author relies on an online survey conducted among young people aged between 18 and 35 (n = 987). As a result of the study, the author defines three groups of institutions, depending on the degree of trust in them. The study confirms the hypothesis that young people loyal to the government demonstrate greater trust in traditional and state institutions. It also reveals that, in general, young people put post-materialistic values in the first place, while materialistic values are more characteristic of the youth loyal to the government. The author concludes that the level of the political trust towards a certain institution among loyal and oppositional youth differs depending on the possibility of influencing the institution. The trust of loyal youth is based on the importance of social status, and the trust of oppositional youth is based on the freedom of expression.
The Memory Policy of the Second World War in the Post-Yugoslav Republics: Symbolic and Commemorative Aspects
Authors: Pomiguev Ilya A. , Salakhetdinov Eldar R.
Published: November 2021

The paper analyses the politics of memory of the World War II (WWII) in socialist Yugoslavia and compares the corresponding commemorative practices in the post-Yugoslav republics. The focus is on the design of holidays and memorial dates that reflect the symbolic and valuable attitudes of society, as well as the trajectory of nation-building. The formation of the state metanarrative in post-war Yugoslavia was closely related to the monopolisation of the leadership roles of the national liberation war by the communists, who united the six South Slavic nations in their struggle against the Nazi invaders. The state holidays and memorial days were derived from the history of resistance to foreign occupiers and internal enemies in order to legitimise and strengthen the triumph of the new socialist order. Alternative Yugoslavian non-communist movements, especially the Ustash and Chetniks who were potentially capable of competing in the symbolic field, were declared class enemies, reactionary elements, and quislings. As the processes of disintegration increased in socialist Yugoslavia, there were several attempts to revise its ideological attitudes and symbolic heritage of WWII. Nevertheless, as the study shows these attempts became, rather, a marginal phenomenon, and most post-Yugoslav states retained the commemorative, albeit de-ideologised, practices of the previous period.

Environmental Characteristics has several components, including the quality of the Environment and Environmental Resources which consist of mineral resources, energy resources, land, land resources, biological resources, and water resources. The provinces in Java, Sumatra, Kalimantan, dan Sulawesi still rely on natural resources for their economic growth. Environmental Quality can be measured by various indices, some of which are the Air Quality Index and the Water Quality Index. One of the problems in the National Economic Recovery during the Covid-19 Pandemic Period is the unavailability of studies and research related to similarities and differences in environmental characteristics to identify provinces that have the potential to prioritize the distribution of Funds/Budgets from the Central Government. Knowing the Similarities and Differences in Characteristics is also needed in determining the Destination Areas for comparative studies from one province to another. For this reason, it is necessary to recommend environmental sector policies as material for the preparation of regulations and the use of appropriate technology in overcoming environmental problems. Analysis of Variance Comparison of Environmental Characteristics and Resources of the Provinces on the four Big Islands in Indonesia shows a significant F - Statistics value, so a Tukey HSD Post Hoc Test is needed to recommend Priority Provinces based on similarities and differences in characteristics in the context of Strengthening the Environmental Sector, as well as recommendations for similarities between regions as a material for consideration for comparative studies between Regional / Provincial Governments.

Published: November 2021

Purpose: To evaluate the association between microscopic hematuria (MH) detected by surveillance urinalysis and cancer recurrence in nonmuscle invasive bladder cancer (NMIBC) patients.Materials and Methods: A total of 1,082 NMIBC patients who underwent transurethral resection of bladder tumor (TURB) procedures at Asan Medical Center between January 2017 and December 2019 were included. We retrospectively reviewed the follow-up data for these cases including cystoscopy, urinalysis, and urine cytology. The association between urine testing and cancer recurrence was assessed by both univariable and multivariable logistic regression analysis.Results: The study patients had a median age of 68 years (interquartile range, 60–75 years) and comprised 898 men and 184 women. Among the 1,428 TURB procedures conducted in this series, 548 of the lesions (38.4%) were diagnosed as low-grade and 880 (61.6%) as highgrade cancers. A total of 3,309 follow-up cystoscopies were conducted during the study period and were divided into high-grade (HG) (2,011 cases) and low-grade (LG) (1,298 cases) groups according to the latest TURB pathology. MH was found to have a statistically significant association with NMIBC recurrence in both the LG (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.107–2.223; p=0.011) and HG (OR, 1.90; 95% CI, 1.434–2.517; p<0.001) groups.Conclusions: Urinalysis during follow-up may provide important information on cancer recurrence in NMIBC patients.

Published: November 2021

Background: Hepatic steatosis is associated with increased surgical
complications in patients undergoing bariatric surgery. The aim of this
study was to evaluate the effect of phentermine in reducing hepatic
steatosis, adipose tissue and surgical complications in patients
undergoing bariatric surgery. Methods: This study is a two-arm,
double-blind, randomized, controlled pilot trial of 64 adult subjects
with BMI >35 kg/m2 selected for bariatric surgery
randomized to phentermine 15 mg once daily for 8 week or placebo. Both
groups adhered to a hypocaloric diet and individualized exercise
program. The primary end point was the reduce frequency of hepatic
steatosis measured by ultrasound and the reduce adipose tissue through
fat mass in total kilograms or percentage. Key secondary points were the
prevalence of surgical complications. Baseline and final biochemical
parameters and blood pressure too were assessments. Results: Phentermine
group the frequency of hepatic steatosis decreased 19%, and the
percentage of patients with a normal ultrasound increased from 9% to
20% (p= 0.053). Likewise, the decrease in fat mass in kilograms was
greater in the phentermine group (56.1 kg vs. 51.8 kg, p=0.02), and a
significant decrease in the HOMA-IR index was observed regardless of
weight loss. No differences in surgical complications were observed
between groups. Phentermine was well tolerated; no differences were
observed in the frequency of adverse events between the groups.
Conclusions: Phentermine decreased the proportion of individuals with
hepatic steatosis by 19%, promoted a greater loss of fat mass in
kilograms, and decreased insulin resistance among candidates for
bariatric surgery.
How to handle the delayed or the missed dose of edoxaban in patients with non-valvular atrial fibrillation: model-informed remedial strategy
Authors: Yin Yi-wei , Liu Xiaoqin , Gu Jiaqin , Li Ziran , Jiao Zheng
Published: November 2021

Aim: Edoxaban is a non-vitamin K antagonist oral anticoagulant (NOAC)
widely used for long-term stroke prevention in patients with
non-valvular atrial fibrillation (NVAF). Adherence to NOACs is
unsatisfactory and decreases over time. The aim of this study was to
explore appropriated remedial dosing regimens for non-adherent
edoxaban-treated NVAF patients through the Monte Carlo simulation.
Methods: Six proposed regimens were compared with the recommendations in
the European Heart Rhythm Association (EHRA) guide regarding the trough
total deviation time considering both edoxaban plasma concentration and
inactive factor Xa activity. Monte Carlo simulations were performed
using RxODE based on the published population
pharmacokinetics/pharmacodynamics model. Results: The proposed remedial
strategies were different from EHRA recommendations and were related to
delay duration. The missed dose can be taken immediately if the delay
time is within 11 h. When the delay period is between 12 and 19 h, a
half dose followed by a regular dosing schedule is recommended. When the
delay time exceeds 19 h, a full dose followed by a half dose is
preferred compared to that recommended in the EHRA guide. Our proposed
strategies resulted in a shorter total deviation time than EHRA guide.
Conclusion: PK/PD modelling and simulation are effective in developing
and evaluating the remedial strategies of edoxaban, which could help
maximize its therapeutic effect.
An ensemble feature method for food classification
Authors: Martinel Niki , Micheloni Christian , Piciarelli Claudio
Published: November 2021

In the last years, several works on automatic image-based food recognition have been proposed, often based on texture feature extraction and classification. However, there is still a lack of proper comparisons to evaluate which approaches are better suited for this specific task. In this work, we adopt a Random Forest classifier to measure the performances of different texture filter banks and feature encoding techniques on three different food image datasets. Comparative results are given to show the performance of each considered approach, as well as to compare the proposed Random Forest classifiers with other feature-based state-of-the-art solutions.
A fast compact difference scheme for the fourth-order multi-term fractional sub-diffusion equation with non-smooth solution
Authors: Cen Dakang , Wang Zhibo , Mo Yan
Published: November 2021

In this paper, we develop a fast compact difference scheme for the
fourth-order multi-term fractional sub-diffusion equation with Neumann
boundary conditions. Combining L1 formula on graded meshes and the efficient
sum-of-exponentials approximation to the kernels, the proposed scheme
recovers the losing temporal convergence accuracy and spares the
computational costs. Meanwhile, difficulty caused by the Neumann boundary
conditions and fourth-order derivative is also carefully handled. The unique
solvability, unconditional stability and convergence of the proposed scheme
are analyzed by the energy method. At last, the theoretical results are
verified by numerical experiments.

Liquid phase sintering, I: Computer study of skeletal settling and solid phase extrication in a normal gravity environment
Authors: Nikolic Z.S.
Published: November 2021

In this paper we will investigate gravity induced skeletal settling during liquid phase sintering. In this approach skeletal settling will be combined with extrication of some solidphase domains. The main goal will be the need to relate dissolution, diffusion and precipitation phenomena to essential geometric and topological changes of the tungstennickel porous microstructure influenced by differential skeletal settling due to large density difference between tungsten domains and the matrix. This study will be based on domain topology (no shape restriction) and control-volume methodology. The microstructural evolution will be simulated by computation of displacement of the center of mass (combined gravity induced settling and random motion) and mass transport due to dissolution and precipitation at the interfaces between solid-phase and liquid matrix.
Influence of Mn site doping on electrical resistivity of polycrystalline La1-yAyMn1-xBxO3 (A=Ba, Sr; B=Cu, Cr, Co) Manganites
Authors: Paunovic N. , Popovic Z.V. , Cantarero A. , Sapina F.
Published: November 2021

We have the measured electrical resistivity of La1-yBayMn1-xCuxO3 (0.17?y?0.30; 0.04?x?0.10), La1-ySryMn1-xCrxO3 and La1-ySryMn1-xCoxO3 (0.270?y?0.294; 0.02?x?0.10) polycrystalline samples in the 25-325 K temperature range. The increase of Mn site doping concentration leads to an increase of the electrical resistivity of the samples and the appearance of a ?double-peak? structure in the electrical resistivity versus temperature graphs. The first peak represents the insulator-metal transition in vicinity of the paramagnetic-ferromagnetic transition (TC). We have found that the intensity of the second peak increases with an increase of concentration of Mn substituents, due to the hole scattering by the random potential of the Mn site impurities.

Six different powders were synthesized by applying the method based on selfpropagating room temperature reaction (SPRT) between metallic nitrates and sodium hydroxide. The method is known to assure very precise stoichiometry of the final product in comparison with a tailored composition. Rietveld refinement was employed to get structural information on the synthesized powder. An increase of Nd ion concentration increases the unit cell parameters and average bond distances. We have shown that all obtained powders were solid solutions with a fluorite-type crystal structure and all powder particles were of nanometric size (about 3 nm).
