Determinant and Weyl anomaly of Dirac operator: a holographic derivation [PDF]

, 2011
We present a holographic formula relating functional determinants: the fermion determinant in the one-loop effective action of bulk spinors in an asymptotically locally AdS background, and the determinant of the two-point function of the dual operator at

Dopamine Modulation of Prefrontal Cortex Activity Is Manifold and Operates at Multiple Temporal and Spatial Scales

Cell Reports, 2019
Summary: Although the function of dopamine in subcortical structures is largely limited to reward and movement, dopamine neurotransmission in the prefrontal cortex (PFC) is critical to a multitude of temporally and functionally diverse processes, such as

Rarefied elliptic hypergeometric functions [PDF]

, 2018
Two exact evaluation formulae for multiple rarefied elliptic beta integrals related to the simplest lens space are proved. They generalize evaluations of the type I and II elliptic beta integrals attached to the root system $C_n$. In a special $n=1$ case,

Human umbilical cord-derived mesenchymal stem cells utilise Activin-A to suppress Interferon-gamma production by natural killer cells.

Frontiers in Immunology, 2014
Following allogeneic hematopoietic stem cell transplantation (HSCT), interferon (IFN)-gamma levels in the recipient’s body can strongly influence the clinical outcome.

Polyharmonic systems involving critical nonlinearities with sign-changing weight functions

Electronic Journal of Differential Equations, 2020
This article concerns the existence of multiple solutions of the polyharmonic system involving critical nonlinearities with sign-changing weight functions $$\displaylines{ (-\Delta)^mu = \lambda f(x) |u|^{r-2}u+ \frac{\beta}{\beta+\gamma} h(x ...

Selective coupling between theta phase and neocortical fast gamma oscillations during REM-sleep in mice.

PLoS ONE, 2011
BackgroundThe mammalian brain expresses a wide range of state-dependent network oscillations which vary in frequency and spatial extension. Such rhythms can entrain multiple neurons into coherent patterns of activity, consistent with a role in behaviour,

Multiple scattering effects on inclusive particle production in the large-x regime

, 2013
We study the multiple scattering effects on inclusive particle production in p+A and $\gamma$+A collisions. Specifically, we concentrate on the region where the parton momentum fraction in the nucleus $x\sim {\cal O}(1)$ and incoherent multiple ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Emerging Themes from EBV and KSHV microRNA Targets

Viruses, 2012
EBV and KSHV are both gamma-herpesviruses which express multiple viral microRNAs. Various methods have been used to investigate the functions of these microRNAs, largely through identification of microRNA target genes. Surprisingly, these related viruses

Functional determinants on Moebius corners

, 1995
A general method of finding functional determinants is presented that depends on the asymptotic behaviour of the resolvent. Its application to the case of a bounded trihedral corner for which the eigenvalues are known only implicitly is outlined and a ...
