Permanence in $N$ species nonautonomous competitive reaction-diffusion-advection system of Kolmogorov type in heterogeneous environment

Electronic Journal of Qualitative Theory of Differential Equations, 2018
One of the important concept in population dynamics is finding conditions under which the population can coexist. Mathematically formulation of this problem we call permanence or uniform persistence.

Real‐World Safety and Effectiveness of JAK Inhibitors in Systemic Sclerosis: A Propensity‐Matched Study From the EUSTAR Cohort

Arthritis Care &Research, EarlyView.
Objective JAK inhibitors (JAKi) have shown promising effects in early‐phase studies of systemic sclerosis (SSc). We aimed to assess the safety and explore the effectiveness of JAKi compared to conventional immunosuppressants in SSc. Methods A longitudinal retrospective study of the European Scleroderma Trials and Research Group (EUSTAR) cohort was ...

Sensitivity analysis of residency and site fidelity estimations to variations in sampling effort and individual catchability Análisis de sensibilidad en estimaciones de residencia y fidelidad al sitio a variaciones en el esfuerzo y capturabilidad individual

Revista Mexicana de Biodiversidad, 2012
Mark-recapture techniques are fundamental for assessing marine mammal population dynamics and individual temporal patterns. Since biases imposed by field conditions are generally unknown, we simulated variations in sampling effort (m) and maximum ...

L'Educació permanent

Educar, 1985
After briefly mentioning the origin of this movement, the author defines continuing education, stating the differences with other concepts such as adult education, recicling courses, leisure society. Continuing education has nothing to do with a generalization of school. It is an anthropological revision, not a methodological issue.

The Lupus Damage Index Revision Program: Results From the Item Generation and Reduction Phases

Arthritis Care &Research, EarlyView.
Objective A data‐driven and expert/patient consensus‐based project to develop a revised Systemic Lupus International Collaborating Clinics (SLICC)/American College of Rheumatology (ACR) Damage Index (SDI) is under way supported by SLICC, ACR, and the Lupus Foundation of America. Our objective is to report the item generation and reduction phase results

Permanent and determinant

27th Annual Symposium on Foundations of Computer Science (sfcs 1986), 1986
This paper gives the bound \(m>\sqrt{2}n-6\sqrt{n}\) as the smallest possible dimension m for which the n-dimensional permanent function might be expressible as an m-dimensional determinant function. The proof uses algebraic geometry studying the singular loci of the permanent and determinant functions.

Employment Trajectories of Patients With Systemic Lupus Erythematosus and Factors Driving Transitions Between States

Arthritis Care &Research, EarlyView.
Objective Systemic lupus erythematosus (SLE) significantly impacts employment capacity. This study aimed to investigate the impact of burden of disease activity, damage, and treatment on employment outcomes and transitions in patients with SLE. Methods Using data from a single center, we analyzed employment transitions, adjusted mean disease activity ...

Analysis of a single species with diffusion in a polluted environment

Electronic Journal of Differential Equations, 2006
In this paper, the effect of diffusion on the permanence and extinction in the polluted environment is studied by a single population diffusive system in two patches.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

Advanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

Advanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
