Fish and Fisheries, Volume 26, Issue 5, Page 848-865, September 2025.ABSTRACT For data‐limited fish species, sustainable management frequently relies on biological metrics that are derived from life‐history trait data, as opposed to high‐resolution time series of catch and abundance. These biological metrics are used to assess a species' recovery potential at low population densities, as well as their extinction risk ...

Mira Variables Based on Emission Lines in LAMOST DR9
The Astrophysical JournalWe present a sample of 335 Mira variables, extracted from DR9 of the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. These variables are characterized by the Balmer emissions (H δ , H γ , H β , and H α ) and the metal emissions

Envelope loss of RGB/AGB stars and the formation of hot subdwarfs
EPJ Web of Conferences, 2013 Low mass stars may lose their envelopes in the first giant branch (RGB) or the asymptotic giant branch (AGB) via envelope ejection (i.e. superwind). The envelope loss of AGB stars leads to the formation of carbon-oxygen (CO) white dwarfs (WDs), while the

An Innovative Tool for Measuring Sunlight Propagation Through Different Snowpacks
Earth and Space Science, Volume 12, Issue 8, August 2025.Abstract Sunlight penetration in the snowpack plays a fundamental role in many environmental processes, ranging from local energy balance to snow microbiology and can potentially contribute to climate change. In addition, many photochemical reactions typically occur in the snowpack driven by solar radiation.

Stellar evolution as seen by mixed modes
EPJ Web of Conferences, 2015 The detection of mixed modes in subgiants and red giants allows us to monitor stellar evolution from the main sequence to the asymptotic giant branch and draw seismic evolutionary tracks.

Introduction to Asymptotic Giant Branch Stars
Journal of Physics: Conference Series, 2016 A brief introduction on the main characteristics of the asymptotic giant branch stars (briefly: AGB) is presented. We describe a link to observations and outline basic features of theoretical modeling of these important evolutionary phases of stars. The most important aspects of the AGB stars is not only because they are the progenitors of white dwarfs,

EPJ Web of Conferences, 2013 The recognition that planets may survive the late stages of stellar evolution, and the prospects for finding them around White Dwarfs, are growing. We discuss two aspects governing planetary survival through stellar evolution to the White Dwarf stage ...

First giant branch and asymptotic giant branch stars in nearby aggregates
The Astronomical Journal, 1991 The properties of the brightest red stars in several aggregates in the Galaxy are compared with theoretical models. 22 asymptotic giant branch (AGB) stars are identified, four of which are in the thermally pulsing AGB (TPAGB) phase and four of which are TPAGB carbon stars.

Edge of Chaos Theory Unveils the First and Simplest Ever Reported Hodgkin–Huxley Neuristor
Advanced Electronic Materials, Volume 11, Issue 8, June 2025.This manuscript presents the first and simplest ever‐reported electrical cell, which leverages one memristor on Edge of Chaos to reproduce the three‐bifurcation cascade, marking the entire life cycle from birth to extinction via All‐to‐None effect of an electrical spike, also referred to as Action Potential, across axon membranes under monotonic ...
