Radar scene generation for tactical decision aids [PDF]

The Mueller matrix and polarization covariance matrix for polarimetric radar systems was studied. The clutter was modeled by a layer of random permittivity, described by a three-dimensional correlation function, with variance, and horizontal and vertical

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Digital Sovereignty and the EU's Identity Between Technological Innovation and European Values

JCMS: Journal of Common Market Studies, EarlyView.
Abstract The debate around ‘digital sovereignty’ identifies tensions rooted in the disparity between the EU's considerable economic and regulatory power in digital matters and its limited mandate and capabilities in foreign policy. Artificial intelligence (AI) is considered a strategic industry in Europe and abroad.

Import competition and stock price crash risk

Journal of Financial Research, EarlyView.
Abstract We investigate how globalization‐induced import competition affects stock price crash risk. Import competition increases price pressure and reduces profit margins, prompting managers to withhold negative information, resulting in higher crash risk. Based on a sample of US manufacturing firms from 1974 to 2019, we find that firms whose products

Variation in trabecular bone microarchitecture across rhesus macaque (Macaca mulatta) load‐bearing joints

Journal of Anatomy, EarlyView.
Aging of bone density (BV/TV) is regional: Forelimb [left] elements gain bone sporadically (orange) but hind limb elements [right] lose bone globally (blue). Abstract Globally, human population structure is quickly trending older, increasing the prevalence and systemic burden of age‐related skeletal disorders such as osteoporosis.

Exploitation or Exploration? Innovation Strategy in Response to Rivals' M&A

Journal of Management Studies, EarlyView.
Abstract This paper investigates the impact of rivals' Mergers and Acquisitions (M&A) activities on the innovation orientation of firms that are not directly involved in these transactions, hereafter referred to as focal firms. Drawing on the Awareness‐Motivation‐Capability (AMC) framework, we find that rivals' M&A activities positively affect a focal ...

Contrasting patterns of population structure in two habitat‐forming kelp species in southeastern Australia

Journal of Phycology, EarlyView.
Abstract The distribution and connectivity of species around the globe are changing at a rapid pace. Increasing sea temperatures are a driving factor of changes in temperate macroalgal distributions. Southeast Australia is considered a global ocean‐warming hotspot, where macroalgal populations are predicted to decline significantly by 2100.

Samplify: a versatile tool for image‐based segmentation and annotation of seed abortion phenotypes

New Phytologist, EarlyView.
Summary Automated seed phenotyping has wide applications in research and agriculture and relies on easy‐to‐use platforms and pipelines. Seed phenotyping in the model species Arabidopsis thaliana poses a significant challenge due to the large number of tiny seeds produced by individual plants, which are difficult to manually separate and count.

Beneficial rhizobacteria and virus infection modulate the soybean metabolome and influence the feeding preferences of the virus vector Epilachna varivestis

New Phytologist, EarlyView.
Summary Beneficial rhizobacteria and viral pathogens can both alter host plant phenotypes, yet little is known about how their simultaneous presence influences plant metabolism and species interactions. We investigated how two rhizobacteria, Bradyrhizobium japonicum and Delftia acidovorans, together with bean pod mottle virus (BPMV), shape soybean ...
