Neutron activation analysis of multimetallic accumulation in dolomites [PDF]
Hemijska Industrija, 2008 The reason for exploring polymetallic ores, which are found in dolomite structures of the Veovača and Borovica zone near Vareš, lies in the fact that there is very little information about its chemical structure.

Nonparametric regression using deep neural networks with ReLU activation function [PDF]
Annals of Statistics, 2017 Consider the multivariate nonparametric regression model. It is shown that estimators based on sparsely connected deep neural networks with ReLU activation function and properly chosen network architecture achieve the minimax rates of convergence (up to $

T-Cell activation: a queuing theory analysis at low agonist density [PDF]
, 2006 We analyze a simple linear triggering model of the T-cell receptor (TCR) within the framework of queuing theory, in which TCRs enter the queue upon full activation and exit by downregulation.

Cosmogenic-neutron activation of TeO2 and implications for neutrinoless double-beta decay experiments [PDF]
, 2015 Flux-averaged cross sections for cosmogenic-neutron activation of natural tellurium were measured using a neutron beam containing neutrons of kinetic energies up to $\sim$800 MeV, and having an energy spectrum similar to that of cosmic-ray neutrons at ...

Synergistic effects of targeted PI3K signaling inhibition and chemotherapy in liposarcoma. [PDF]
, 2014 While liposarcoma is the second most common soft tissue malignant tumor, the molecular pathogenesis in this malignancy is poorly understood. Our goal was therefore to expand the understanding of molecular mechanisms that drive liposarcoma and identify ...

Superintense laser-driven photon activation analysis
Communications Physics, 2021 Photon activation analysis is a non-destructive technique for material characterization that require high photon energies. Here, laser-driven accelerator is considered as a high-energy photon source and its optimization for photon activation analysis ...

Evaluation of Muscle Function by Means of a Muscle-Specific and a Global Index
Sensors, 2021 Gait analysis applications in clinics are still uncommon, for three main reasons: (1) the considerable time needed to prepare the subject for the examination; (2) the lack of user-independent tools; (3) the large variability of muscle activation patterns
