Cosmological dynamics of spatially flat Einstein–Gauss–Bonnet models in various dimensions: high-dimensional \(\Lambda \) -term case

In this paper we perform a systematic study of spatially flat \([(3+D)+1]\)-dimensional Einstein–Gauss–Bonnet cosmological models with \(\Lambda \)-term. We consider models that topologically are the product of two flat isotropic subspaces with different scale factors. One of these subspaces is three-dimensional and represents our space and the other is D-dimensional and represents ...

Nitrogen effects on the pelagic food web are modified by dissolved organic carbon

Global environmental change has altered the nitrogen (N) cycle and enhanced terrestrial dissolved organic carbon (DOC) loadings to northern boreal lakes. However, it is still unclear how enhanced N availability affects pelagic food web efficiency (FWE) and crustacean zooplankton growth in N limited boreal lakes. Here, we performed in situ mesocosm experiments in six unproductive ...

Medium response in JEWEL and its impact on jet shape observables in heavy ion collisions

Realistic modeling of medium-jet interactions in heavy ion collisions is becoming increasingly important to successfully predict jet structure and shape observables. In Jewel, all partons belonging to the parton showers initiated by hard scattered partons undergo collisions with thermal partons from the medium, leading to both elastic and radiative energy loss. The recoiling medium ...

Long-term spironolactone treatment reduces coronary TRPC expression, vasoconstriction, and atherosclerosis in metabolic syndrome pigs

Coronary transient receptor potential canonical (TRPC) channel expression is elevated in metabolic syndrome (MetS). However, differential contribution of TRPCs to coronary pathology in MetS is not fully elucidated. We investigated the roles of TRPC1 and TRPC6 isoforms in coronary arteries of MetS pigs and determined whether long-term treatment with a mineralocorticoid receptor ...

Path-integral derivation of black-hole radiance inside the de-Rham–Gabadadze–Tolley formulation of massive gravity

If we apply the path-integral formulation in order to analyze the particle creation process of black holes inside the non-linear formulation of massive gravity, it is possible to demonstrate that the effect of the extra degrees of freedom is to deform the periodicity of the poles of the propagator in the complex t-plane. This might create the effect of extra particle creation ...

Bosonic partition functions at nonzero (imaginary) chemical potential

We consider bosonic random matrix partition functions at nonzero chemical potential and compare the chiral condensate, the baryon number density and the baryon number susceptibility to the result of the corresponding fermionic partition function. We find that as long as results are finite, the phase transition of the fermionic theory persists in the bosonic theory. However, in case ...

Culture and emotion perception: comparing Canadian and Japanese children’s and parents’ context sensitivity

Prior research on the perception of facial expressions suggests that East Asians are more likely than North Americans to incorporate the expressions of background figures into their judgment of a central figure’s emotion (Masuda et al. in J Pers Soc Psychol 94:365–381, 2008b). However, little research has examined this issue in the context of developmental science, especially ...

When Bereaved of Everything: Objects from the Concentration Camp of Ravensbrück as Expressions of Resistance, Memory, and Identity

When survivors from the Ravensbrück concentration camp arrived in Sweden in spring 1945, some of the objects they brought with them from the camp were collected and preserved. These are modest in appearance, but were – as oral testimonies show – invaluable in camp. The concentration camp context of obliteration stretches the limits of interpretation of material culture to its ...

Antivirals for allosteric inhibition of Zika virus using a homology model and experimentally determined structure of envelope protein

Objective An approach to inhibiting enveloped flaviviruses is to deter the ability of the envelope protein(s) binding onto glycoproteins. In previous work, using a small ~100-amino acid homology model of Zika virus envelope protein (ZVEP), we proved the susceptibility of Zika virus to inhibition. In this work, we verify the efficacy of the homology model based antiviral search ...

\({{SO(d,1)}}\) -Invariant Yang–Baxter Operators and the dS/CFT Correspondence

We propose a model for the dS/CFT correspondence. The model is constructed in terms of a “Yang–Baxter operator” R for unitary representations of the de Sitter group \({SO(d,1)}\). This R-operator is shown to satisfy the Yang–Baxter equation, unitarity, as well as certain analyticity relations, including in particular a crossing symmetry. With the aid of this operator we construct: ...
