A Testis‐Specific Aralkylamine N‐Acetyltransferase Regulates Dimorphic Sperm Function and Male Fertility in Moths

open access: yesAdvanced Science, EarlyView.
We identify a Lepidoptera‐conserved testis‐specific arylalkylamine N‐acetyltransferase (LTNAT) that governs male moth fertility via a novel mechanism. LTNAT loss disrupts eupyrene sperm mitochondrial derivatives and impairs apyrene sperm motility, offering a safe molecular target for innovative pesticides and genetic pest control.

Spawner-recruit relationships and fish stock carrying capacity in aquatic ecosystems [PDF]

open access: yesMarine Ecology Progress Series, 2003
Few marine ecologists have addressed important questions about the relative produc- tivity and carrying capacity of different ecosystems required to support fish populations. Whereas many researchers have investigated interannual variability in recruitment within a stock, we asked whether relationships between spawner abundance and subsequent ...

Spin Hall Nano‐Antenna

open access: yesAdvanced Science, EarlyView.
ABSTRACT The spin Hall effect is a well‐known phenomenon in spintronics that has found numerous applications in digital electronics (memory and logic), but relatively few in analog electronics. Practically the only analog application in widespread use is the spin Hall nano‐oscillator (SHNO) that delivers a high frequency alternating current or voltage ...

Life-history habitat suitability modelling of a potential invasive alien species, smallmouth bass (Micropterus dolomieu), in South Korea

open access: yesEcological Indicators, 2023
The aim of this study was to predict the distribution of a potential invasive alien species, smallmouth bass (Micropterus dolomieu), in South Korea using a life-history-based habitat suitability model.

The sustainable management of the New Zealand longfin eel : a bioeconomic analysis : a thesis presented in partial fulfilment of the requirements for the degree of Master of Applied Economics at Massey University [PDF]

open access: yes, 2002
Annual recruitment of the New Zealand longfin eel (Anguilla dieffenbachii) has declined by around 75 percent since heavy levels of commercial fishing began in the early 1970s.

Keep it simple: three indicators to deal with overfishing [PDF]

open access: yes, 2004
Three simple fisheries indicators are presented: (i) percentage of mature fish in catch, with 100% as target; (ii) percent of specimens with optimum length in catch, with 100% as target; and (iii) percentage of ‘mega-spawners‘ in catch, with 0% as target,

Flexible Memory: Progress, Challenges, and Opportunities

open access: yesAdvanced Intelligent Discovery, EarlyView.
Flexible memory technology is crucial for flexible electronics integration. This review covers its historical evolution, evaluates rigid systems, proposes a flexible memory framework based on multiple mechanisms, stresses material design's role, presents a coupling model for performance optimization, and points out future directions.

Status of the Pacific Mackerel resource during 1996 management recommendations for the fishery [PDF]

open access: yes, 1997
The California fishery for Pacific mackerel (Scomber japonicus) has declined precipitously since 1990. Statewide landings during 1995 continued the downward trend, and totaled only 9,185 short tons.

Abolishment of spawner-isolated mortality virus and where the remaining science leads

open access: yesJournal of General Virology, 2023
In the late 1980s, there was histological and electron microscopy evidence for a parvovirus-like virus in Australian prawns. The data were consistent with infectious hypodermal and haematopoietic necrosis virus (IHHNV). However, these cases did not fit the then current paradigms of the known viruses and sequencing did not find any meaningful sequence ...

The Interoperability Challenge in DFT Workflows Across Implementations

open access: yesAdvanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.
