In Silico Functional Analysis of Variants in Genes Associated with Sudden Cardiac Death in Cases of the National Institute of Legal Medicine of Colombia

: Diseases of cardiovascular origin such as cardiomiopathies and channelopathíes are the main causes of sudden cardiac death and in some cases are difficult to diagnose during autoposy. We present an in silico analysis using bioinformatic tools, for the analysis of possibly pathogenic variants in genes associated with sudden cardiac death. Algorithms were used to predict pathogenicity, predicting the impact of SNPs on proteins, genomic specificity andprotein-protein interaction. We found that variants in the KCNH2, ANK3, TTN, CAV3 and DSP genes cause structural alterations, molecular, cellular and interstitial changes in the heart that can trigger sudden death.
A Single-Chip Single-Antenna Radar for Remote Vital Sign Monitoring

This article proposes an effective way to use self-injection locking (SIL) in a radar system to detect human chest cavity movement for vital signs monitoring with minimal hardware. The proposed approach expands the idea of using a phase-locked loop (PLL) system as a demodulator and a single antenna, making the system more compact. The system includes ON-chip dc offset cancellation for system initialization. This work investigates and compares an $LC$ -based voltage-controlled oscillator (LCVCO) and a ring voltage-controlled oscillator (RVCO) in terms of primary sensitivity for motion detection and phase noise. A study of injection-locking of both the LCVCO and RVCO is also established. The study shows that the RVCO is superior to the LCVCO in terms of sensitivity while the phase noise does not differ significantly as the frequencies of interest are very small, i.e., heart rate and respiration are bandwidth-limited to a few hertz. To verify the proposed idea, a design of both systems, an LCVCO-based PLL and an RVCO-based PLL, was implemented in 65 nm CMOS technology at 1.5 GHz. The simulation and measurement results confirm the idea proposed: the RVCO shows better performance across all metrics, e.g., higher sensitivity by 4 dB, lower power consumption by 30%, and reduced area (almost half) compared to the LCVCO.
Optimization of a Power Management Process in a Printed Electronics Smart Label System

The topic of this research was to investigate and optimize power management of a printed electronics prototype device used for quality assurance of Ready-to-Eat food products. Printed electronics enables the manufacturing of thin, lightweight products and components, which can be part of a functional system. In order to maintain the lightweight and thin nature of the products, a small and thin battery is integrated in these types of autonomous systems. Power consumption of the system should be kept at low level to enable the use of printed batteries.The optimization of power consumption was done at software level. The goal was to reach so low power consumption that the printed prototype device can operate on a food package long enough using a small sized printed battery. Another goal was to study the effects of different operating modes to the power consumption and how much is it possible to affect to them.The research started by studying power management in embedded systems and finding out what was the device’s power consumption at the start. After that, a plan for optimization procedures was done. The optimization procedures were executed one by one and effects to power consumption was measured. This revealed exactly how much each procedure was affecting to power consumption. Usability also played a key role in finding the optimal solution. As a result, the device’s current consumption was optimized to the desired level where it can reach the targeted operating time. All functionalities and usability were maintained in the power optimization process.
Fast Patch-based De-blurring with Directional-oriented Kernel Estimation

This paper proposes a fast patch-based de-blurring algorithm including kernel estimation based on the angle between the edge and the blur direction. For de-blurring, image patches from the most informative edges in the blurry image are used to estimate a kernel with low computational cost. Moreover, the kernels of each patch are estimated based on the correlation between the edge direction and the blur direction. This makes the final kernel more reliable and creates an accurate latent image from the blurry image. The combination of directionally oriented kernel estimation and patch-based de-blurring is faster and more accurate than existing state-of-the art methods. Experimental results using various test images show that the proposed method achieves its objectives: speed and accuracy.
A generalization of Pythagorean triples for desirable quadrilaterals

We explore the generalization of famous Pythagorean triples (a, b, c) for triangles to Pythagorean quadruples (a, b, c, d) for desirable quadrilaterals. Using number theory and geometrical techniques including Diophantine equations and Ptolemy’s Theorem, we show that there are infinite number of such quadrilaterals with specific relations between their sides and diagonals. We conclude our paper with an open question for further investigation.
Effects of Rootstock and Training System on Tree Canopy, Fruit Quality and Phytochemicals of ‘0900 Ziraat’ and ‘Regina’ Sweet Cherry Cultivars

: Both ‘0900 Ziraat’ and ‘Regina’ grafted on ‘Krymsk 5’, or ‘Piku 1’ rootstocks were trained to either Upright Fruiting Offshoots (UFO), Super Slender Axe (SSA) or Kym Green Bush (KGB) training systems. Vegetative growth of the tree, determined by measuring trunk cross-sectional area (TCSA), canopy volume and leaf area, differed significantly, depending on the cultivar x rootstock x training system combination. In general, ‘Krymsk 5’ rootstock resulted in trees with significantly thicker trunks (TCSA: 37.75 cm 2 ) and increased leaf area (up to 86.97 cm 2 ). Fruit weight and fruit quality parameters including Hunter a*, firmness, TSS and acidity were variable between rootstocks and training systems and often not significantly different between treatments. In some years however, significant differences were highly dependent on the training system and rootstock interactions. Higher concentrations of bioactive phytochemical concentrations for total monomeric anthocyanin and antioxidant concentrations were mostly associated with the UFO training system in conjunction with the ‘Krymsk 5’ rootstock suggesting that these are linked to increased tree vigour and increased leaf surface area.
Thermal coupling model of a traveling flexible printing electronical membrane subjected to nonlinear electrostatical force

A flexible printing electronical membrane is an electron equipment made by precisely spraying conductive metal ink such as silver on a soft membrane substrate. With its advantages of light weight and flexibility, it can adapt to changing working environments and is widely used in aerospace, wearable electronics and other fields. Nevertheless, during the manufacturing preparation of roll-to-roll printing membranes, the high-speed movement of printing electronical membranes under tension is affected by the impact of hot air from the drying oven and the electrostatic interference generated by friction in transmission, which restricts the overprint accuracy and preparation velocity of flexible electronical membranes. To address this issue, the nonlinear forced vibrational characteristics of a traveling flexible printing electronical membrane on temperature coupling subjected to nonlinear electrostatic force were investigated. The roll-to-roll printed intelligent RFID electron membrane is the research target. On the basis of the energy approach and the heat conduction equation considering the effect of deformation, the nonlinear vibrational equations of an axially traveling flexible printing electronical membrane coupled with temperature under the function of nonlinear electrostatical excitation force were derived. The Bubnov–Galerkin algorithm was applied to discretize the vibration partial differential equations; by making full use of the quartic Runge–Kutta numerical algorithm to calculate the approximate solution of equations, the phase portraits, Poincaré maps, time history diagrams, power spectra, and bifurcation plots of the nonlinear vibrations of the traveling printing electronical membrane were used to explore the effects of movement velocities, electrostatical field, and thermal coupling coefficients. The findings obtained the stable working domain and the divergence instability domain of the traveling flexible printing electronic membrane, which provided a theory fundamental for enhancing the stable craft of a printing electronical membrane.
Accelerated electrons for in situ peak intensity monitoring of tightly focused femtosecond laser radiation at high intensities

A simple technique for diagnosing the peak intensity of a tightly focused high-power femtosecond laser beam is proposed. The method is based on tracking the angular distribution of electrons directly accelerated in the waist of linearly polarized tightly focused radiation. Field ionization of a low density (<1016 cm−3) gas (e.g. helium) creates electrons, which are accelerated by the electromagnetic field and leave the focal area with relativistic residual energy. Three dimensional simulations utilizing the particle-in-cell code and test particle method revealed that the maximum of angular distribution of high energy electrons shifts to the beam axis with increase in the peak laser intensity. Hence, the peak laser intensity may be well evaluated by detecting a direction of the flux of large momentum particles. The experimentally measured angular characteristics of electrons accelerated in the caustic region of tightly focused ∼1 TW laser radiation with an estimated vacuum peak intensity above 1019 W cm−2 have shown reasonable agreement with the numerical simulations. Shot-to-shot variation of the pulse energy leads to deviations in the particles angular distribution, opening the opportunity to control the focusing quality in situ, in each laser shot.
Molecular identification of Anaplasma platys in cattle by nested PCR

Background and Objectives: Anaplasmosis is a zoonotic disease caused by Gram-negative bacterium from Anaplasmataceae family. Anaplasma causes high economic losses worldwide. 16S rRNA analysis was used to diagnose Anaplasma platys in Cattle. Phylogenetic tree and estimation of evolutionary divergence between A. platys isolates were performed. Materials and Methods: A total of 60 blood samples were collected from a cattle farm in AL-Diwaniyah province. 16S rRNA gene was identified using nested PCR. Overall, 40% of cattle that were chosen to collect the blood were identified to be infected with A. platys. Results: The results have shown presence of targeting partial region of 16S rRNA gene in 24 samples out of 60. Sequencing results of 10 samples have revealed that the phylogenetic tree was divided in to two separate clades. Five isolates of A. platys-Iraq (accession no. OP646782, OP646783, OP646784, OP646790, and OP646791) were located in one clade with the A. platys-China (accession no. MN193068.1). While, five isolates (accession no. OP646785, OP646786, OP646787, OP646788, OP646789) were in different clade with two isolates of A. platys-Africa and A. platys-Zambia in distinct branches, close to the Rickettsiales. Conclusion: The phylogenetic study of A. platys sequences indicated that the isolates were collected from a cattle farm in Al-Dewaniyah were similar and close related to A. platys-China, A. platys-Zambia and A. platys-Africa). This study suggests that cattle can be considered a reservoir of A. platys.
Redefining Management Competencies in Industry: A Critical Analysis on HR Digital Transformation Effort

Aim/Purpose: In order to address the objective of the research aim of this paper, the influence of digital leadership competencies on employee satisfaction is examined. Background: Digital leadership competencies are indispensable in the digital world of work today. Leaders need them to survive in the digital environment and act successfully together with their employees. However, relevant leadership competencies in the digital transformation have hardly been studied so far, and there is a lack of models that determine them and derive support needs for leaders. Methodology: In order to examine the relationship between a manager's digital competencies and employee satisfaction, a survey of employees is used as a research method. A quantitative research approach investigates the characteristics considered digital leadership competencies. The underlying research question is addressed by using an online questionnaire completed independently by participants from different industries and different professional groups. In terms of using a reliability analysis, Cronbach's alpha was calculated with the data set obtained in the survey. Findings: The results show a relationship between digital leadership skills and em-ployee satisfaction in the digital age. Derived from the findings, this re-quires the adaptation of further training measures by the responsible HR departments Impact on Society: The advancing digitalisation is also changing the requirements for the compe-tencies of managers. By adapting leadership skills, employee satisfaction in the company can be promoted in the long term in a transforming work environ-ment. In addition, the research has shown that a manager's ability to build net-works, both within organisations and with external partners, can significantly impact employee satisfaction. Thus, along with the competencies of trust, tech-nology affinity and cooperativeness, it represents an essential digital ability of leaders
Optimal disturbance rejection controllers design for synchronised output regulation of time-delayed multi-agent systems

An optimal disturbance rejection controller design method is put forward analytically for the synchronised output regulation of time-delayed multi-agent systems (MAS). All kinds of linear MAS can be described by a novel block diagram based on transfer functions in a unified framework. For each subsystem without intercommunication, the optimal output, input and balancing output–input load disturbance rejection controllers are designed independently. A filter is used to be in series with each controller to not only stabilise the whole systems but also achieve a tradeoff between nominal performance and robustness by adjusting a single tuning parameter. The proposed distributed H 2 controllers calculated by algebraic solution perform better capacity of disturbance attenuation than the conventional given-structured protocols. Two simulation examples demonstrate the validity of the new algorithm.
Analytical solution of the Cattaneo - Vernotte equation (non-Fourier heat conduction)

The theory of Fourier heat conduction predicts accurately the temperature profiles of a system in a non-equilibrium steady state. However, in the case of transient states at the nanoscale, its applicability is significantly limited. The limitation of the classical Fourier’s theory was overcome by C. Cattaneo and P. Vernotte who developed the theory of non-Fourier heat conduction in 1958. Although this new theory has been used in various thermal science areas, it requires considerable mathematical skills for calculating analytical solutions. The aim of this study was the identification of a newer and a simpler type of solution for the hyperbolic partial differential equations of the non-Fourier heat conduction. This constitutes the first trial in a series of planned studies. By inspecting each term included in the proposed solution, the theoretical feasibility of the solution was achieved. The new analytical solution for the non-Fourier heat conduction is a simple exponential function that is compared to the existing data for justification. Although the proposed solution partially satisfies the Cattaneo–Vernotte equation, it cannot simulate a thermal wave behavior. However, the results of this study indicate that it is possible to obtain the theoretical solution of the Cattaneo–Vernotte equation by improving the form of the proposed solution.
The Influence of Transformational Leadership, Strategic Planning, and Organizational Culture on Organizational Performance Mediation by Organizational Commitment at the Indonesian Navy's Education and Training Doctrine Development Command (KODIKLATAL)

This study aims to analyze the effect of Transformational Leadership, Strategic Planning, and Organizational Culture on Organizational Performance mediated by Organizational Commitment at the Indonesian Navy's Education and Training Doctrine Development Command (NETDDC). The data collection method used in this study was by distributing questionnaires, using simple random sampling technique. This study used 323 respondents. The data analysis method used in this study is the Structural Equation Method (SEM) processed with AMOS version 24 software. Based on the results of data processing in this study, it shows that the increase in Organizational Performance was more influenced by Organizational Culture. Transformational Leadership has a positive and significant influence on Organizational Commitment that is greater than Strategic Planning and Organizational Culture. The role of Organizational Commitment as a mediating variable further strengthens the effect of Organizational Culture on Organizational Performance. Thus, decision making in improving Organizational Performance in NETDDC can be carried out through the Organizational Culture approach as an alternative which is supported by Transformational Leadership which has a major influence on Organizational Commitment. The implications of this research encourage managerial decision makers in the Indonesian Navy and NETDDC to optimize organizational performance.
Importance of shielding and mechanical characterization of GTAW on Ti-6AL-4V alloy sheet

Abstract Welding and joining Titanium and its alloys are always challenging because getting a contamination-free joint is difficult with arc welding. For this concern, an attempt was made with and without shielding arrangements using the Gas Tungsten Arc Welding (GTAW) process on the Ti-6Al-4V alloy sheet. To study the presence of oxygen and other elements with respect to surface colourization at the weld zone, an Energy-dispersive X-ray spectroscopy (EDX) analysis is carried out. Based on the EDX analysis, post-flow and pre-flow shielding gases are also included in the operation window. Bead on Plate (BoP) trials are performed using the shielding arrangement setup and selected parameters on the thin sheets (2 mm) of Ti-6Al-4V. After examining the BoP trails, defect-free joins in a 2 mm sheet are fabricated using the optimal welding parameters. The microstructure of the joint is captured and compared with the simulation work. Compared to the base metal, coarse and enormous grains are identified at the weld zone. Due to the proper shielding, no cracks appeared in the joint subjected to the three-point bend test. The considerable heat input during the GTAW process resulted in the nucleation of (ά) in FZ, as spotted in the TEM images. The microhardness value at FZ for base metal is 373 HV and 332 HV, respectively. It is confirmed that the suggested shielding setup could prevent contamination in welds resulting in better mechanical properties.
ANALYSIS OF DIFFRACTION GRAPHENE GRATINGS USING THE C-METHOD AND DESIGN OF A TERAHERTZ POLARIZER

We analyze relief graphene gratings by the coordinate transformation method (the Cmethod). This method is also used for analysis of multilayer gratings with graphene sheets at the interfaces. By using this method, we are able to obtain the efficiency of deep graphene gratings with fast convergence rate while previous methods are limited to very shallow graphene gratings. Moreover, a terahertz polarizer is designed by relief graphene grating. Polarization extinction ratio and transmittance of single-layer and double-layer polarizer are simulated by the C-method. Doublelayer polarizer gives extinction ratio from 22 dB to 10 dB over a frequency range of 1 GHz to 4 THz.
Perturbed fixed point iterative methods based on pattern structure

We introduce a new idea of algorithmic structure, called assigning algorithm, using a finite collection of a subclass of strictly quasi‐nonexpansive operators. This new algorithm allows the iteration vectors to take steps on a pattern which is based on a connected directed acyclic graph. The sequential, simultaneous, and string‐averaging methods for solving convex feasibility problems are the special cases of the new algorithm which may be used to reduce idle time of processors in parallel implementations. We give a convergence analysis for such algorithmic structure with perturbation. Also, we extend some existence results of the split common fixed point problem based on the new algorithm. The performance of the new algorithm is illustrated with numerical examples from computed tomography.

Portanto, o termo qualidade de silagem geralmente se refere a eficiencia do processo fermentativo para promover a conservacao desse valor na forragem ensilada e nao tem sido utilizado para designar o seu valor nutritivo do volumoso.
Three rapidly convergent parareal solvers with application to time‐dependent PDEs with fractional Laplacian

Time‐dependent PDEs with fractional Laplacian ( − Δ)α play a fundamental role in many fields and approximating ( − Δ)α usually leads to ODEs' system like u′(t) + Au(t) = g(t) with A = Qα, where Q∈Rm×m is a sparse symmetric positive definite matrix and α > 0 denotes the fractional order. The parareal algorithm is an ideal solver for this kind of problems, which is iterative and is characterized by two propagators G and F . The propagators G and F are respectively associated with large step size ΔT and small step size Δt, where ΔT = JΔt and J⩾2 is an integer. If we fix the G ‐propagator to the Implicit‐Euler method and choose for F some proper Runge–Kutta (RK) methods, such as the second‐order and third‐order singly diagonally implicit RK methods, previous studies show that the convergence factors of the corresponding parareal solvers can satisfy ρ≈13,∀J⩾2 and ∀σ(A)⊂[0,+∞) , where σ(A) is the spectrum of the matrix A. In this paper, we show that by choosing these two RK methods as the F ‐propagator, the convergence factors can reach 112 , provided the one‐stage complex Rosenbrock method is used as the G ‐propagator. If we choose for both G and F , the complex Rosenbrock method, we show that the convergence factor of the resulting parareal solver can also reach 112 . Numerical results are given to support our theoretical conclusions. Copyright © 2017 John Wiley & Sons, Ltd.
