Embedability between right-angled Artin groups

open access: yes, 2011
In this article we study the right-angled Artin subgroups of a given right-angled Artin group. Starting with a graph $\gam$, we produce a new graph through a purely combinatorial procedure, and call it the extension graph $\gam^e$ of $\gam$. We produce a

Splenomegaly, Cardiomegaly, and Osteoporosis in a Child with Gaucher Disease

open access: yesCase Reports in Pediatrics, 2011
A 15-month-old girl, born to the consanguineous parents, was referred with the sign of massive splenomegaly associated with thrombocytopenia and anemia. Plasma Chitotriosidase estimation was carried out as a screening test and was found to be normal with

Analog Implementation of a Spiking Neuron with Memristive Synapses for Deep Learning Processing

open access: yesMathematics
Analog neuromorphic prototyping is essential for designing and testing spiking neuron models that use memristive devices as synapses. These prototypes can have various circuit configurations, implying different response behaviors that custom silicon ...

Geodesic acoustic modes in a fluid model of tokamak plasma : the effects of finite beta and collisionality

open access: yes, 2015
Starting from the Braginskii equations, relevant for the tokamak edge region, a complete set of nonlinear equations for the geodesic acoustic modes (GAM) has been derived which includes collisionality, plasma beta and external sources of particle ...

New constraints on a light CP-odd Higgs boson and related NMSSM Ideal Higgs Scenarios [PDF]

open access: yes, 2010
Recent BaBar limits on $\br(\Upsilon(3S)\to \gam a\to \gam \tau^+\tau^-)$ and $\br(\Upsilon(3S)\to \gam a\to \gam \mu^+\mu^-)$ provide increased constraints on the $a b\anti b$ coupling of a CP-odd Higgs boson, $a$, with ...

Estimation of the maximum sustainable yield of giant grenadier Albatrossia pectoralis (Macrouridae) in the Russian Far East using Bayesian surplus production model JABBA

open access: yesИзвестия ТИНРО, 2023
Statistical estimates for the exploitable stock of giant grenadier are determined, by fishing zones in the Russian Far East, and interannual dynamics of the species biomass is considered using historical data on catches and abundance.

Strongly Coupled Matter-Field and Non-Analytic Decay Rate of Dipole Molecules in a Waveguide

open access: yes, 2004
The decay rate $\gam$ of an excited dipole molecule inside a waveguide is evaluated for the strongly coupled matter-field case near a cutoff frequency $\ome_c$ without using perturbation analysis. Due to the singularity in the density of photon states at
