Public good-driven release of heterogeneous resources leads to genotypic diversification of an isogenic yeast population. [PDF]

Evolution, 2022
Abstract Understanding the basis of biological diversity remains a central problem in evolutionary biology. Using microbial systems, adaptive diversification has been studied in (a) spatially heterogeneous environments, (b) temporally segregated resources, and (c) resource specialization in a homogeneous environment.

Combined Acupoints for the Treatment of Patients with Obesity: An Association Rule Analysis. [PDF]

Evid Based Complement Alternat Med, 2022
Obesity is a prevalent metabolic disease that increases the risk of other diseases, such as hypertension, diabetes, hyperlipidemia, cardiovascular disease, and certain cancers. A meta‐analysis of 11 randomized sham‐controlled trials indicates that acupuncture had adjuvant benefits in improving simple obesity, and previous studies have reported that ...

Monotone Quantifiers Emerge via Iterated Learning. [PDF]

Cogn Sci, 2021
Abstract Natural languages exhibit many semantic universals, that is, properties of meaning shared across all languages. In this paper, we develop an explanation of one very prominent semantic universal, the monotonicity universal. While the existing work has shown that quantifiers satisfying the monotonicity universal are easier to learn, we provide a

Retrospective Development of an AI Model Combining Ultrasound and Clinical Data for Pediatric Appendicitis Differentiation. [PDF]

Emerg Med Int
Purpose To differentiate complicated appendicitis (CA) from uncomplicated appendicitis (UA) in children, we developed and validated an artificial intelligence (AI) model using a multimodal approach integrating ultrasound images and clinical data. Methods A retrospective analysis was performed on 372 pathologically confirmed pediatric appendicitis cases

Application of Mathematical Models in Economic Variable Input and Output Models under the Scientific Visualization.

Comput Intell Neurosci, 2022
At present, with the development of society and economy, some new problems have emerged continuously. Among them, the more serious problem is that enterprises pay too much attention to economic benefits, which leads to problems in the development of many enterprises.

Neuroprotective and Memory-Enhancing Effect of the Combined Extract of Purple Waxy Corn Cob and Pandan in Ovariectomized Rats. [PDF]

Oxid Med Cell Longev, 2017
The neuroprotectant and memory enhancer supplement for menopause is required due to the side effects of hormone replacement therapy. Since purple waxy corn cob and pandan leaves exert antioxidant and acetylcholinesterase inhibition (AChEI) effects, we hypothesized that the combined extract of both plants (PCP) might provide synergistic effect leading ...

Decay of solutions for strain gradient mixtures

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 103, Issue 2, February 2023., 2023
Abstract We study antiplane shear deformations for isotropic and homogeneous strain gradient mixtures of the Kelvin‐Voigt type in a cylinder. Our aim is to analyze the behaviour of the solutions with respect to the time variable when a dissipative structural mechanism is considered. We study three different cases, each at a time. For each case we prove

Critical Percolation Exploration Path and SLE(6): a Proof of Convergence [PDF]

, 2006
It was argued by Schramm and Smirnov that the critical site percolation exploration path on the triangular lattice converges in distribution to the trace of chordal SLE(6). We provide here a detailed proof, which relies on Smirnov's theorem that crossing

Exact Solutions to the Sine-Gordon Equation [PDF]

, 2010
A systematic method is presented to provide various equivalent solution formulas for exact solutions to the sine-Gordon equation. Such solutions are analytic in the spatial variable $x$ and the temporal variable $t,$ and they are exponentially asymptotic
