Radiative decay rates of impurity states in semiconductor nanocrystals

AIP Advances, 2015
Doped semiconductor nanocrystals is a versatile material base for contemporary photonics and optoelectronics devices. Here, for the first time to the best of our knowledge, we theoretically calculate the radiative decay rates of the lowest-energy states ...

Quasiclassical Representation of Autoionization Decay Rates in Parabolic Coordinates

, 2000
A simple general analytical formula is obtained for autoionization decay rates in parabolic quantum numbers for highly excited atomic states. The formula is applicable for atomic transitions without change of principle quantum nunbers (Delta n=0 ...

Decay rates for inverses of band matrices

, 1984
Spectral theory and classical approximation theory are used to give a new proof of the exponential decay of the entries of the inverse of band matrices. The rate of decay of A − 1

Disproof of solar influence on the decay rates of $^{90}$Sr/$^{90}$Y [PDF]

, 2014
A custom-built liquid scintillation counter was used for long-term measurements of 90 Sr / 90 Y sources. The detector system is equipped with an automated sample changer and three photomultiplier tubes, which makes the application of the triple-to-double

Multidimensional Profiling of MRI‐Negative Temporal Lobe Epilepsy Uncovers Distinct Phenotypes

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Although hippocampal sclerosis (TLE‐HS) represents the most frequent cause of temporal lobe epilepsy (TLE), up to 30% of patients show no lesion on visual MRI inspection (TLE‐MRIneg). These cases pose diagnostic and therapeutic challenges and are underrepresented in surgical series.

Elevated Connectivity During Language Processing Is Associated With Cognitive Performance in SeLECTS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Self‐Limited Epilepsy with Centrotemporal Spikes (SeLECTS) is associated with language impairments despite seizures originating in the motor cortex, suggesting aberrant cross‐network interactions. Here we tested whether functional connectivity in SeLECTS during language tasks predicts language performance.

Integrating Incidence Angle Dependencies Into the Clustering-Based Segmentation of SAR Images

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Synthetic aperture radar systems perform signal acquisition under varying incidence angles and register an implicit intensity decay from near to far range. Owing to the geometrical interaction between microwaves and the imaged targets, the rates at which

Decay rates and survival probabilities in open quantum systems

, 2002
We provide the first statistical analysis of the decay rates of strongly driven 3D atomic Rydberg states. The distribution of the rates exhibits universal features due to Anderson localization, while universality of the time dependent decay requires ...

SPG4 and Dementia: Expanding the Clinical Spectrum

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Hereditary spastic paraplegia (HSP) is a group of disorders characterized by progressive spasticity and lower limb weakness, with mutations in SPG4/SPAST being the most common cause. Detailed studies and clinical and molecular comparisons across different populations are missing.

How to calculate α-decay rates in the future?

EPJ Web of Conferences, 2016
New elements discovered during past decades have been created in fusion reactions where a lighter nucleus is collided with a heavier one. The new elements created often decay by emitting α particles.
