Ecological Entomology, EarlyView.The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

East European Journal of PhysicsRecently, there has been much interest in investigating outstanding problems of cosmology with modified theories of gravity. The Brans-Dicke theory of gravity is one such theory developed by Brans and Dicke absorbing Mach’s principle into the General ...

Temperature elevation broadens the dietary niche of an insect herbivore
Ecological Entomology, EarlyView.The realised dietary niche in Chrysomela lapponica was the narrowest at 10°C, whereas higher temperatures (15–25°C) broadened the dietary niche by increasing preference for and survival on suboptimal host plants. Elevated temperature broadened the realised dietary niche through both direct effects on beetles and indirect effects mediated by temperature‐

New Journal of PhysicsWe show that bright squeezed vacuum light, combined with a single-shot quadrature measurement of the post-interaction light, enables the ultrafast generation of macroscopic quantum states in matter.

Journal of Applied Entomology, EarlyView.ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

New Journal of Physics, 2013 We propose a fast and efficient technique to create classes of highly entangled states of trapped ions, such as arbitrary Dicke states and superpositions of them, e.g. NOON states.

Friedmann cosmology with decaying vacuum density in Brans–Dicke theory
European Physical Journal C: Particles and Fields, 2021 In this paper, we study Friedmann cosmology with time-varying vacuum energy density in the context of Brans–Dicke theory. We consider an isotropic and homogeneous flat space, filled with a matter-dominated perfect fluid and a dynamical cosmological term $

A Public Values Framework for AI Governance: Evidence From US Federal AI Policymaking
Public Administration, EarlyView.ABSTRACT Governments at all levels are grappling with AI's implications for public administration. Because federal actions often establish the principles guiding wider governance efforts, this study asks how US federal AI policies reflect—or fail to reflect—core public values.

Emergent universe by tunneling in a Jordan-Brans-Dicke theory
European Physical Journal C: Particles and Fields, 2019 In this work we study an alternative scheme for an Emergent Universe scenario in the context of a Jordan-Brans-Dicke theory, where the universe is initially in a truly static state supported by a scalar field located in a false vacuum. The model presents

Plant Biology, EarlyView.Herbicide residues in soil disrupt plant–insect signalling, reducing the effectiveness of biological pest control. Abstract Plants under herbivore attack emit distinct blends of herbivore‐induced plant volatiles (HIPVs) which serve as signalling cues for predatory insects.
