This study proceeds from the database of two patient groups. Patients in first group underwent intraabdominal anastomotic operation technique and they come from a selected hospital in USA. Patients in second group underwent extraabdominal anastomotic operation technique and they come from the Clinic of Surgery at the University Hospital Ostrava (Czech Republic). Both groups have more than 200 patients. Both operation techniques are compared in the study taking into account the following variables: risk of post-operative morbidity, conversion, operation time, BMI, ASA, etc. Risk of morbidity will be quantified, compared for different patient groups and deeply discussed in the paper, by the use of advanced statistical methods, as logistic regression, Agresti-Coull and Wilson interval, hypotheses testing, etc. To be comparable both data groups had to be adapted and modified at the earliest by the use of a proper method based on propensity score. © 2016 IEEE.

The purpose of this paper is to describe the parallelization of PragTic - a fatigue damage simulator. There is a discussion about the former version inefficiency (caused by frequent I/O operations), parallel implementation and parallelized PragTic scalability testing. The parallelization is done at the node level where the nodes are defined in the context of the finite element mesh. We also ran a simple model example (hundreds of nodes), real world example (millions of nodes) and our approach is to test using numerical experiments where we achieve weak parallel scalability. At the end of the article, the results of numerical experiments are depicted in tables and graphs.

A genomic database of all Earth’s eukaryotic species could contribute to many scientific discoveries;however, only a tiny fraction of species have genomic information available. In 2018, scientists across the world united under the Earth BioGenome Project (EBP), aiming to produce a database of highquality reference genomes containing all ~1.5 million recognized eukaryotic species. As the European node of the EBP, the European Reference Genome Atlas (ERGA) sought to implement a new decentralised, equitable and inclusive model for producing reference genomes. For this, ERGA launched a Pilot Project establishing the first distributed reference genome production infrastructure and testing it on 98 eukaryotic species from 33 European countries. Here we outline the infrastructure and explore its effectiveness for scaling high-quality reference genome production, whilst considering equity and inclusion. The outcomes and lessons learned provide a solid foundation for ERGA while offering key learnings to other transnational, national genomic resource projects and the EBP. © The Author(s) 2024, corrected publication 2024.

This paper shows main results of research emphasized on stress-strain behavior of the 316L stainless steel under proportional as well as non-proportional loading. The 316L steel shows significant additional hardening due to non-proportional loading. The results from all realized fatigue tests including the number of cycles to crack initiation and cyclic hardening/softening curves are presented. Two ways of fatigue parameters estimation are applied with comparable results. Important conclusions for the cyclic plasticity modeling considering investigated material are also discussed with emphasize on observed Non-Masing behavior and strain range dependent cyclic hardening.

We develop a simple yet powerful technique to study Bogoliubov-Cherenkov radiation by producing a pulsed atom laser from a strongly confined Bose-Einstein condensate. Such radiation results when the atom laser pulse falls past a Bose-Einstein condensate at high-hypersonic speeds, modifying the spatial profile to display a characteristic twin jet structure and a complicated interference pattern. The experimental observations are in excellent agreement with mean-field numerical simulations and an analytic theory. Due to the highly hypersonic regime reached in our experiment, this system offers a highly controllable platform for future studies of condensed-matter analogs of quantum electrodynamics at ultrarelativistic speeds.

Beryllium (Be) is an important material with wide applications ranging from aerospace components to X-ray equipments. Yet a precise understanding of its phase diagram remains elusive. We have investigated the phase stability of Be using a recently developed hybrid free energy computation method that accounts for anharmonic effects by invoking phonon quasiparticles. We find that the hcp → bcc transition occurs near the melting curve at 0 Copyright © 2017, The Authors. All rights reserved.

We study three notions of shadowing: classical shadowing, limit (or asymptotic) shadowing, and s-limit shadowing. We show that classical and s-limit shadowing coincide for tent maps and, more generally, for piecewise linear interval maps with constant slopes, and are further equivalent to the linking property introduced by Chen in [15]. We also construct a system which exhibits shadowing but not limit shadowing, and we study how shadowing properties transfer to maximal transitive subsystems and inverse limits (sometimes called natural extensions). Where practicable, we show that our results are best possible by means of *** Codes 37E05 (Primary), 37C50, 37B10, 54H20, 26A18 (Secondary) Copyright © 2017, The Authors. All rights reserved.

We have extended Cosmos++, a multi-dimensional unstructured adaptive mesh code for solving the covariant Newtonian and general relativistic radiation magnetohydrodynamic (MHD) equations, to accommodate both discrete finite volume and arbitrarily high order finite element structures. The new finite element implementation, called CosmosDG, is based on a discontinuous Galerkin (DG) formulation, using both entropy-based artificial viscosity and slope limiting procedures for regularization of shocks. High order multi-stage forward Euler and strong stability preserving Runge-Kutta time integration options complement high order spatial discretization. We have also added flexibility in the code infrastructure allowing for both adaptive mesh and adaptive basis order refinement to be performed separately or simultaneously in a local (cell-by-cell) manner. We discuss in this report the DG formulation and present tests demonstrating the robustness, accuracy, and convergence of our numerical methods applied to special and general relativistic MHD, though we note an equivalent capability currently also exists in CosmosDG for Newtonian systems.

Specialized computational chemistry packages have permanently reshaped the landscape of chemical and materials science by providing tools to support and guide experimental efforts and for the prediction of atomistic and electronic properties. In this regard, electronic structure packages have played a special role by using first-principle-driven methodologies to model complex chemical and materials processes. Over the last few decades, the rapid development of computing technologies and the tremendous increase in computational power have offered a unique chance to study complex transformations using sophisticated and predictive many-body techniques that describe correlated behavior of electrons in molecular and condensed phase systems at different levels of theory. In enabling these simulations, novel parallel algorithms have been able to take advantage of computational resources to address the polynomial scaling of electronic structure methods. In this paper, we briefly review the NWChem computational chemistry suite, including its history, design principles, parallel tools, current capabilities, outreach and outlook.
