Reduced fertilization regimes could boost biocontrol service without reducing crop yield
Insect Science, EarlyView.Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Complexity of dynamical sphere in self-interacting Brans–Dicke gravity
European Physical Journal C: Particles and Fields, 2020 This paper aims to derive a definition of complexity for a dynamic spherical system in the background of self-interacting Brans–Dicke gravity. We measure complexity of the structure in terms of inhomogeneous energy density, anisotropic pressure and ...

Integrative Zoology, EarlyView.Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

Nuclear Physics B, 2017 We consider an exactly solvable inhomogeneous Dicke model which describes an interaction between a disordered ensemble of two-level systems with single mode boson field.

Entomologia Experimentalis et Applicata, EarlyView.Actia interrupta is an important larval tachinid parasitoid during low‐density populations of the eastern spruce budworm. In the late 1980s during the outbreak collapse, Meteorus trachynotus was initially the most important species, but was replaced by A. interrupta. Host patch size and density had no impact on the parasitism rates by A.

Ecological Entomology, EarlyView.In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

Ecological Entomology, EarlyView.Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Brans-Dicke supergravity and the Lambda naturalness problem [PDF]
, 2015 The successful $\Lambda CDM$ cosmological model requires a small but nonzero $\Lambda$ which appears to have an unnaturally small value compared to the supersymmetry breaking scale, typically $O(10^{-60}) m_{3/2}^4$ for $m_{3/2} \sim 10 TeV$.

Dicke-State-Initialized Grover’s Algorithm for Solving the Hitting Set Problem
Engineering ProceedingsThe Dicke-state-initialized Grover’s algorithm is used for the hitting set problem (DSIGA-HSP) to efficiently solve the NP-Complete HSP. By initializing the working qubits in the Dicke state Dkn, the algorithm restricts the search domain to subsets of ...

Entanglement between more than two hundred macroscopic atomic ensembles in a solid
Nature Communications, 2017 Multipartite entanglement is of both fundamental and practical interest, but is notoriously difficult to witness and characterise. Here, Zarkeshian et al.
