Commercial Product Based on Metarhizium Anisopliae Affects Survival, Midgut Morphology, and Behavior in the Stingless Bee Scaptotrigona depilis (Hymenoptera: Apidae)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

CP-violation in the Weinberg 3HDM potential

open access: yesJournal of High Energy Physics
We explore the phenomenology of Weinberg’s ℤ 2 × ℤ 2 symmetric three-Higgs-doublet potential, allowing for spontaneous violation of CP due to complex vacuum expectation values.

Assessing genetic diversity in a reintroduced Mediterranean griffon vulture Gyps fulvus population to inform long‐term conservation management

open access: yesWildlife Biology, EarlyView.
Reintroductions play a key role in conservation biology. Their long‐term success strongly depends on maximizing the genetic diversity of founders, as well as on ensuring ecological connectivity with adjacent populations. Accordingly, evaluating the conservation status of reintroduced populations to limit the loss of their genetic diversity requires ...

A Validation Method for the Enhanced Fuzzy Min‐Max Neural Network With Application to Heart Disease Data Classification

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This study investigates early detection of heart diseases using a new Enhanced Fuzzy Min‐Max (EFMM) neural network. Two key modifications are introduced: a refined EFMM contraction procedure during the learning phase to reduce data distortion and information loss, and a new weighted validation method to optimise hyperbox selection and improve ...

CP violation

open access: yes, 1992
We review the phenomenology of CP violation. the first part is a general discussion of CP violation in meson decays and in fermion electric dipole moments. The second part describes CP violation in in the Standard Model.

CP violation at ATLAS [PDF]

open access: yes, 2013
A measurement of several properties of the Bs meson, including the CP-violating weak phase phis and the mixing-induced width difference ΔΓs, is performed using the decay Bs → J/ψ(μ+μ−)phi(K+K−), from a dataset of 4.9 fb−1 of integrated luminosity ...

“Women of the Happy Life”: Prostitution, Public Morality, and Venereal Disease in US‐Occupied Nicaragua, 1912–33

open access: yesGender &History, EarlyView.
ABSTRACT During the years of the US occupation (1912–33), Nicaragua's government legally regulated prostitution. Convinced of their objectives to protect society's moral and public health, politicians embarked on a long struggle to apprehend, quarantine, and segregate female prostitutes nationwide.

Aphid and endosymbiont sensitivity to heatwaves is misaligned across life stages

open access: yesInsect Science, EarlyView.
Aphids depend on the obligate symbiont Buchnera aphidicola, which may constrain thermal tolerance. Using a factorial heatwave experiment, we exposed nymphs and adults to moderate or extreme temperatures and measured fitness and symbiont responses.

Now You See Them, Now You Don't: Understanding New Hire Ghosting and Its Antecedents

open access: yesHuman Resource Management Journal, EarlyView.
ABSTRACT New hire ghosting, in which applicants accept an offer and then quit before their first day without notice, is an emerging and consequential staffing phenomenon. Drawing on job embeddedness theory, we conceptualize new hire ghosting as a form of pre‐entry withdrawal influenced by dispositional risk and the fragile fit, links, and sacrifice ...

Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...
