INFLUENCE OF (Ca 2+ )O ON CARDIOMYOCYTE INJURY BY DEFIBRILLATOR-LIKE SHOCKS

Electrical defibrillation, the most effective treatment of life-threatening arrhythmias, such a ventricular fibrillation, is based on the application of shocks to the heart for the reversal of the abnormal rhythm. However, depending on their intensity, defibrillating shocks may cause cell injury and even death. Massive Ca 2+ influx due to electrical sarcolemmal damage contributes to both cell injury and membrane repair. This study aimed at investigating how variation in the extracellular Ca 2+ concentration ((Ca 2+ )o) affects the susceptibility of isolated cardiomyocytes to lethal injury by high-intensity electrical fields. The results indicate that doubling the physiological (Ca 2+ )o did not make the cells more vulnerable to high-intensity electric stimulation, but a 50% decrease in (Ca 2+ )o made the cells less susceptible to the shock-induced lethal injury. In order to make defibrillation procedures safer, studies have shown ways to improve defibrillators or to protect the myocardium with drugs. This study reveals a new point of view in which a safer defibrillation approach might be achieved by changing the medium around the cell.
Performance of fishmeal-free rabbitfish (Siganus lineatus) feed in Palau1

Two 56-day trials were conducted to evaluate the effects on the performance and feed utilization efficiency of four experimental diets formulated with different plantbased meals to completely replace fish meal for juvenile golden-lined rabbitfish (Siganus lineatus). A commercial and currently employed feed was used as control, while the experimental diets were formulated and manufactured with a combination of duckweed (Lentein), fermented soybean (MrFeed Pro50s), soy protein concentrate (Profine), and soybean meal. Each trial had a total of 120 fish (trial 1: 9.29 ± 0.14 g/fish; trial 2: 7.74 ± 0.25 g/fish) stocked in groups of 10 in a total of 12 floating cages (47.7 L) within two 3-ton flow-through tanks (Koror, Palau). Control and experimental diets were fed to quadruplet cages by hand to visual satiation for one hour four times a day to a maximum of 5% body weight in trial 1, and two times per day to a maximum of 3% body weight in trial 2. Trial 1 tested diet 1 (42% Lentein, 15% MrPro50s) and diet 2 (42% Lentein, 15% soybean meal) with no significant differences (p > 0.05) in terms of growth performances (final weight, weight gain and specific growth rate) and feed utilization (feed conversion ratio and protein efficiency ratio), while feed intake was significantly different (p < 0.05). Trial 2 tested diet 3 (23% soy protein concentrate, 20% soybean meal) and diet 4 (27% soy protein concentrate, 10% soybean meal) with significant differences in terms of growth performances but no differences in terms of feed utilization and feed intake. Survival was unaffected by the treatments (p > 0.05).
BRIGHT-DARK SOLITONS OF THE TWO-COMPONENT NONLOCAL NONLINEAR SCHRÖDINGER EQUATIONS COUPLED TO BOUSSINESQ EQUATION

Motivated by the potential applications of multi-component nonlocal nonlinear Schrödinger (NLS) and NLS-type equations in nonlinear optics, the twocomponent nonlocal NLS equation coupled to the Boussinesq (2CNNLS-Boussinesq) equation is proposed and investigated. By employing the Kadomtsev-Petviashvili hierarchy reduction method, the multiple bright-dark soliton solutions, namely, one component featuring solitons with nonzero boundary condition and the other two components featuring solitons with zero boundary condition, are constructed in determinant forms. Based on the asymptotic analysis for the two-solitons, we bring out that the dark twosolitons possess three non-degenerate types and two degenerate types, while the bright two-solitons only admit one non-degenerate type. Additionally, we also consider the resonant-type collision of the bright-dark two-solitons, which is resulted by the phase shifts tending to zero in the collision process. The resonant-type collision can generate periodic waves in the region where the two solitons intersect. For the bright-dark four-solitons, we consider the bound state two-solitons pairs and the corresponding resonant-type collision between the two-solitons pairs. Finally, we also propose the arbitrary N̂ component nonlocal NLS-Boussinesq equation and some other nonlocal versions of the 2CNNLS-Boussinesq equations.
Design optimization for passive adaptive structural networks

The increasing interest in mechanical systems exhibiting enhanced vibration control and shock mitigation characteristics has motivated the study of novel design approaches for the synthesis of scalable systems with passive adaptive dynamic characteristics. In this article, we present a modular design concept to synthesize passive adaptive structures having concurrent high stiffness and high damping capabilities. The goal of this concept is to select linear and nonlinear structural constitutive elements from a predefined set and interconnect them depending on the overall scale and static/dynamic characteristics requested to the final structural assembly. To achieve this goal, an optimization design tool based on the genetic algorithm is developed. The design optimization problems are formulated with both single- and multi-objective functions subject to design constraints on both stiffness and damping characteristics. Using the predefined set of constitutive elements, this design tool synthesizes optimal structural networks in order to meet prescribed structural and damping requirements while exhibiting dynamic characteristics that passively adapt to variable external loading conditions.
Assessing the nexus between mobile financial service usage and inflation – evidence from Bangladesh

This paper set out to uncover the nexus between the propensity of mobile financial service (MFS) usage and inflation in Bangladesh, if any. This paper hypothesizes that the usage of MFS will lead to an increase in the velocity of money, i.e., the ease of using MFS in lieu of cash will lead to money transferring ownership quicker. All things constant, this will lead to inflation—as stipulated by the quantity theory of money. To this end, monthly data pertaining to the general price index, number of MFS agents, number of average daily MFS transactions, number of MFS clients and number of banks supporting MFS transactions have been used ranging from FY16 to FY20, subject to availability. The objective of the paper was to understand the relationship between usage of MFS and inflation, if any. To this end, two models were developed and subsequently tested. Upon undertaking a Johannsen co-integration test, it was found that there is indeed one long run equilibrium relationship between the variables used as per the second model. The use of the Vector Auto Regression (VAR) on model 1 failed to upholster the hypothesis of the paper. The subsequent use of a Vector-Error Correction model (VECM) on model 2 to capture the nexus between the propensity of MFS usage and inflation in Bangladesh also failed to diagnose a statistically significant relationship between MFS velocity and inflation in Bangladesh.
Neural mechanisms of learning and control

A new theory was postulated that the cerebellum, the basal ganglia, and the cerebral cortex have evolved to implement different kinds of learning algorithms: the cerebellum for supervised learning, the basal ganglia for reinforcement learning, and the cerebral cortex for unsupervised learning. Here, we introduce recent advances in motor control and learning, namely, the role of the basal ganglia in acquisition of goal-directed behaviors, learning of internal models by the cerebellum, and decomposition of complex tasks by the competition of predictive models.
A Region Localization Algorithm Based on Anchors within Two Hops for Wireless Sensor Networks

Localization is a fundamental and essential issue for wireless sensor networks (WSNs). In this paper, we present a range-free region localization (RFRL) algorithm for static WSNs, in which each unknown node collects the location information of anchors within its two-hop distance, and then some location information of its one-hop anchors and two-hop anchors are chosen to implement a grid-scan algorithm. Analysis and simulation results show that our algorithm outperforms the other Grid-Scan schemes even when the communication radius is irregular.

Study of charge carrier transport properties and lifetimes in HR GaAs:Cr with Timepix3

The response of a Timepix3 (256 × 256 pixels, pixel pitch 55 μm) detector with a 500 μm thick HR GaAs:Cr sensor was studied in proton beams of 125 MeV at the Danish Centre for Particle Therapy in Aarhus, Denmark and in a 120 GeV/c pion beam at the Super-Proton Synchrotron (SPS) at CERN. The sensor was biased at different voltages and irradiated at different angles. The readout chip was configured to operate in electron and hole collection modes. Measurements at grazing angles allowed to see elongated tracks with well-defined impact and exit points, so that charge carrier production depths could be determined in each pixel. We extracted the charge collection efficiencies and the charge carrier drift times as a function of the distance to the pixel plane. It was found that measured proton tracks are shorter in hole collection than in the case of electron collection, which is explained by the shorter lifetime of holes. At an angle of 60 degrees with respect to the sensor normal, the average track length in hole collection was ∼700 μm and 950 μm in electron collection mode. To understand the experimental findings, models describing the properties of HR GaAs:Cr were implemented into the Allpix2 simulation framework. We added previously presented experimental results describing the dependence of the electron drift velocity on the electric field and validated the response by comparing measurement and simulation for various X- and gamma-ray sources in the energy range of 10–60 keV. By comparison of the experimental and the simulated results, the mobility μ h and the lifetime of holes τ h were estimated as μ h = (320 ± 10) cm2/V/s and τ h = (4.5 ± 0.5) ns.
Development of Google Earth Engine Fire Weather Index Calculator for Indonesian Fire Danger Rating System

Tropical peatlands make up almost ten percent of the land surface in Indonesia, making peat fires detrimental not only for global atmospheric carbon levels, but also to public health and socioeconomic activities in the region. Indonesian Fire Danger Rating System (FDRS) was developed based on the Canadian Forest Fire Weather Index System (CFFWIS), using three different fuel codes and three indices representing fire behaviour. Daily Fire Weather Index (FWI) calculation is done by the Meteorological Climatological and Geophysical Agency (BMKG) with data from its synoptic weather stations network. Distribution of such weather stations are sparse, therefore this paper reports on the development of Fire Weather Index calculator on Google Earth Engine, using high resolution weather data, provided by weather model and remote-sensing open datasets. The resulting application is capable of generating daily maps of FWI components to be used by the Indonesian Fire Danger Rating System.
Spectral efficiency analysis of two-user Downlink PD-NOMA with LTE modulation and coding schemes

Non-orthogonal multiple access (NOMA) is a promising user multiplexing technique for future wireless networks that allows increasing their spectral efficiency (SE). Power-Domain NOMA (PD-NOMA) is one of the most perspective techniques in the NOMA group. It makes it possible to perform the transmission of information symbols of several users within the same time-frequency resource segment (RS) without a spreading code. Many research works show the high efficiency of PD-NOMA compared to the orthogonal multiple access (OMA). However, these results are obtained analytically using Shannon’s formula and not taking into account the real performance of existing modulation and coding schemes (MCS). The issue is that it is impossible to obtain the achievable practical performance of PD-NOMA systems in this way. We obtain the SE in RS of a PD-NOMA system with Long Term Evolution (LTE) MCS’s and compare it with OMA. As a result, we conclude that PD-NOMA gains the system SE when the multiplexed user’s signal-to-noise ratio (SNR) outreaches the threshold of the highest performing MCS provided for the transmission by a MCS table.
Quantization noise in low bit quantization and iterative adaptation to quantization noise in quantizable neural networks

Quantization is one of the most popular and widely used methods of speeding up a neural network. At the moment, the standard is 8-bit uniform quantization. Nevertheless, the use of uniform low-bit quantization (4- and 6-bit quantization) has significant advantages in speed and resource requirements for inference. We present our quantization algorithm that offers advantages when using uniform low-bit quantization. It is faster than quantization-aware training from scratch and more accurate than methods aimed only at selecting thresholds and reducing noise from quantization. We also investigated quantization noise in neural networks for low-bit quantization and concluded that quantization noise is not always a good metric for quantization quality.
SCMA-MIMO system with adaptation to the channel state

Sparse code multiple access (SCMA) is one of the promising implementations of non-orthogonal multiple access (NOMA) methods. SCMA provides high spectral efficiency and a large number of network resources. We describe a communication system with SCMA, space-time block coding (STBC), multiple input multiple output (MIMO) technology, and orthogonal frequency division multiplexing (OFDM). The architecture of such systems, including algorithms of formation and processing of signals is considered. A method for adapting signals to the state of the spatial channel transmission based on information about the matrix of channel coefficients is proposed. The application of such adaptation allows to compensate the influence of the channel and to reduce the probability of bit errors. We consider the bit error rate (BER) performance of the communication system in different channel models and show the effectiveness of the proposed methods.
TiAl-based Ohmic Contacts to p-type 4H-SiC

This paper describes successfully formed ohmic contacts to p-type 4H-SiC based on titanium-aluminum alloys. Four different metallization structures were examined, varying in aluminum layer thickness (25, 50, 75, 100 nm) and with constant thickness of the titanium layer (50 nm). Structures were annealed within the temperature range of 800°C 1100°C and then electrically characterized. The best electrical parameters and linear, ohmic character of contacts demonstrated structures with Al layer thickness equal or greater than that of Ti layer and annealed at temperatures of 1000°C or higher. Keywords—ohmic contact, SiC, silicon carbide, TiAl
Accurate Detection of Malicious Code in PDF Files using Machine Learning.

The 21st century has been the age of technology. The continuous growth in technology has also forced growth in the field of cybersecurity. Cyber-criminal is continuously researching for new ways to perform cyber-crime. PDF files are very popular in the current age. Most of the official documents to learning materials are now been circulated and read in PDF format. Due to its high flexibility in features PDF format has become very popular. Due to these reasons, cyber-criminals are now been using PDF files to exploit systems and perform cybercrime. PDF file formats are being used by individuals who have no knowledge about computer security. So, they are very vulnerable to any form of PDF-based cyber-attack. This thesis aims at developing a system to detect malicious code in PDF files using machine learning algorithms. The thesis will be performing a comparative study of the algorithm to find the algorithm that gives the best results when it comes to PDF malware detection.
Proposal of an Automated Tool for Conducting Usability Inspections based on Nielsen Heuristics

One of the most important aspects that contribute to the competitiveness of applications in the market is usability. Usability can be used in the software development process, both in the design phase and in the evaluation phase, where one of the most widespread methods to evaluate the usability of a software product are usability inspections. In order to specify the results obtained in a usability inspection and to determine the quantitative and qualitative level of compliance with the usability heuristics, it is necessary to specify the criteria associated with the different heuristics to be considered in an inspection. In this paper we propose as a contribution both the definition of a set of evaluation criteria associated with the Nielsen heuristics, and the development of a tool to automate the process of conducting usability inspections based on the defined criteria. The criteria and the proposed tool are intended to serve as a reference for conducting inspections on applications in different application contexts.

LIFE SATISFACTION AMONG AGED WOMEN

Aging is an inevitable development phenomenon leading to certain changes in bodily, psychological, hormonal and social situations. Chronological age (the age of a person) is commonly used to describe the age range of older people. Most countries in developed world have adopted the chronological age of 65 as the definition of “older person” or older. The United Nations has agreed that 65 and over can generally be referred to as old age. Life satisfaction among the elderly is an important concept as it gives us an overall view of the adjustment as well as adaptive coping ability of the individual. The level of satisfaction among the aged effects not only their psychological adjustment, but also physical, emotional and social well-being. The present study was undertaken to study health problems of aged women in Kashmir. The universe comprised of aged women in the age group of 60 years and above. The sample for the present study comprised of 1032 aged women and was taken from all districts of Kashmir region. Life satisfaction scale constructed by Michael J. Salmon and Vincent A. Conte (1984) is used to collect the information. Aged women posses average level of; Career satisfaction, Social satisfaction, Familial satisfaction, Personal satisfaction.
Propagation in Twisted Square Waveguide

The problem of propagation of TE modes in twisted rectangular waveguides has been solved except for the case where one of the propagating modes becomes degenerate. The purpose of this paper is to show how to obtain a solution for degenerate modes in a twisted rectangular waveguide, with emphasis on the particular case of the square waveguide, for which the lowest order mode is degerate. It is shown that the propagation constant for the twisted square waveguide can be expressed as an asymptotic series, the first term being the propagation constant for a straight square waveguide and the first order correction term being of order 1/ L where L is the distance in which the guide makes one full rotation. The propagation constant for a nondegenerate mode in a twisted rectangular waveguide, on the other hand, can be expressed in a similar manner except that the first-order correction term is of order 1/ L/sup2/. Some comments are offered on the nature of the transition when the propagating mode is almost degenerate.
Two-Dimensional Gravitational Displays in Mobile Phones

In this paper, we present a novel type of haptic display for usage in mobile phones. It changes the gravitational properties of the device by shifting an internal weight along two axes. Its utility is explored in a performance study, in which users were estimating positions of the device's actuated center of gravity. The users also participated in qualitative studies: A questionnaire that assessed the perceived qualit y of interacting with the device, and an interview in which they described their experiences with the weight-shifting mobile. Furthermore, this paper suggests three domains of application in which the system may be of benefit: Augmenting digital content with physical mass, ambient displays, and haptically augmented wayfinding.
Evaluation of Environmental Pollution Caused by Heavy Metal Elements in Natural Ground

The pollution of ground water caused by the inflow of drainage water from mudstone excavation sites is a serious issue. It has been recognized that the problem results from the discharge of sulfate generated by the decomposition of pyrite contained in the mudstone. Urban natural ground commonly contains mud sediments, and when the underground environment is altered by underground openings, pollution by acid water originating from these mud sediments may occur. The prediction of pollution is therefore important in constructing underground openings. We used numerical simulation to attempt prediction of the spatial extent of pollution caused by the drainage of acid water with heavy metals from mud sediment.
