Age and growth of the endemic groovebelly stingray (Dasyatis hypostigma), a heavily exploited batoid in the Brazilian Meridional Margin (21–34° S)

Journal of Fish Biology, EarlyView.
Abstract Life‐history data are often lacking for exploited elasmobranchs, jeopardizing proper management and conservation measures for this vulnerable group. Herein, we provided age and growth estimates for the groovebelly stingray (Dasyatis hypostigma), a medium‐sized, heavily exploited batoid endemic to the southwestern Atlantic Ocean.

New Modified Gompertz Probability Distribution With Flexible Hazard Functions

Journal of Probability and Statistics
This paper introduces a new probability model called the modified Gompertz distribution from the base Gompertz distribution by combining its hazard function with first and second degree polynomial (linear and quadratic) functions.

Variation in herbivore defense strategies among plant species differing in elevational distribution and the role of temperature in defense

New Phytologist, EarlyView.
Summary Temperature influences the distribution and performance of both plants and insect herbivores. Consequently, plant–herbivore interactions are likely to vary across thermal gradients, which could affect the evolution of plant defense. Furthermore, temperature fluctuations may elicit immediate changes in defense.

Gompertz curves with seasonality [PDF]

Technological Forecasting and Social Change, 1994
This paper considers an extension of the usual Gompertz curve by allowing the parameters to vary over the seasons. This means that, for example, saturation levels can be different over the year. An estimation and testing method is proposed and illustrated with an example.

The effect of citrus essential oil encapsulation on antioxidant capacity and bacterial growth in a milk matrix during storage

Journal of the Science of Food and Agriculture, Volume 106, Issue 4, Page 2352-2360, 15 March 2026.
Abstract BACKGROUND The functionality of food can be improved by supplementing it with bioactive substances. However, the interactions between these substances and food components can compromise their functional efficacy. This study investigated the potential to reduce functional losses by encapsulating citrus essential oil (CEO) in zein particles (ZPs)

Mechanistic two‐pathway modeling of substrate inhibition in lactic acid bacteria for enhanced fermentation control

Quantitative Biology, Volume 14, Issue 1, March 2026.
Abstract Substrate inhibition in lactic acid bacteria (LAB) fermentation occurs when substrate concentration exceeds a critical value, leading to reduced cell growth and thus inefficient lactic acid production. Many efforts, including experimental and kinetic models, have been devoted to elucidate the possible mechanisms of substrate inhibition ...

Gompertz-Weibull {Gompertz} Type I: A Four-Parameter Generalization of the Weibull Family

Journal of Statistical Theory and Practice
AbstractIn this paper, we provide a construction method that provides greater flexibility in modeling real-world phenomenon by generalizing univariate probability distributions. The Gompertz distribution is used to provide new classes of models through T-X{Y} construction, in a manner we will define as a “proper” generalization, illustrated by ...

Alfalfa‐Based Dehydrated Silage Pellet as a Source of Nutrients in Laying Hens: I. Effects on Animal Performance and Egg Quality

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Alfalfa‐based silage pellets (ABSP) showed significant results regarding production performance, yolk colour and ω‐3 (PUFAs), as well as the ratio ω‐6/ω‐3 (p < 0.05). The ABSP group also exhibited a higher abundance of beneficial bacteria and a lower abundance of pathogenic bacteria compared to the control group (p < 0.05).

Automatic parameter update algorithm for regression models to estimate remaining useful life: Application in an offshore natural gas dehydration unit

The Canadian Journal of Chemical Engineering, Volume 104, Issue 2, Page 935-952, February 2026.
Abstract Remaining useful life (RUL) analysis of equipment prevents failures and assists in maintenance to address impending failures. To achieve this, the advancement of degradation can be measured through a determinant variable. This work presents a new methodology for estimating the number of remaining cycles (NRC), or RUL, of equipment in cyclic ...
