Tight-binding study of structure and vibrations of amorphous silicon

open access: yes, 2004
We present a tight-binding calculation that, for the first time, accurately describes the structural, vibrational and elastic properties of amorphous silicon.

Source characteristics of a moderate earthquake (M 4.9)using empirical Green ?s function technique

open access: yesAnnals of Geophysics, 2002
The rupture process of a moderate earthquake (M 4.9)on 28th January 1999 was analyzed using velocity records at local distances less than 80 km.The characterization of the rupture process was obtained from studying aftershocks distribution,azimuthal ...

Some Reliability Properties of Extropy and its Related Measures Using Quantile Function

open access: yesStatistica, 2021
Extropy is a recent addition to the family of information measures as a complementary dual of Shannon entropy, to measure the uncertainty contained in a probability distribution of a random variable.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity

open access: yesMolecular Oncology, EarlyView.
Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Black swans or dragon kings? A simple test for deviations from the power law [PDF]

open access: yes, 2011
We develop a simple test for deviations from power law tails, which is based on the asymptotic properties of the empirical distribution function. We use this test to answer the question whether great natural disasters, financial crashes or electricity ...

Projection Index with Empirical Distribution Function

open access: yesJapanese journal of applied statistics, 2003
多変量データ解析では,扱う変量の数が増えるとその構造をとらえることが困難になる場合が多い.そこで,多変量データ解析では解釈が容易な低次元にまで次元を縮小する手法が数多く研究されている.特に,1974年にFriedman and Tukeyによって提案された射影追法(Projection Pursuit)は,興味深い構造が現れる低次元空間を求めるという意味で,有効な次元縮小の手法である.従来,射影追跡法は,「興味深い」構造を正規分布から最も離れている分布と定めて特徴検出しているが,「興味深い」構造はデータや解析目的によって異なる.本論文では,特徴検出の際に非特徴的であるとして比較の参照とする標本を定め,その標本の分布から最も離れている分布を探索するように拡張した射影追跡法を提案する.

Implementation of gauss function in determing probability of floods at the gauge station 'Dolenci' on the Crna Reka in Republic of Macedonia [PDF]

open access: yesGeographica Pannonica, 2011
The Gaussian distribution function is symmetric and in hydrological research can be used for the purposes of comparison. After the determination of the parameters and the return probability levels associated with return periods of 2, 5, 10, 25, 50, 100 ...

Predicting and Comparing the Subjective Health Experience of Older Cancer Survivors and Non‐Cancer Survivors: A Modeling Approach

open access: yesAging and Cancer, EarlyView.
This study underscores the significant influence of frailty and vitality on the subjective health experience of older cancer survivors with acceptance and control emerging as salient mediators. These findings affirm the conceptual and empirical robustness of the model highlighting its potential utility in shaping future interventions for older cancer ...

Exploratory Analysis of ELP1 Expression in Whole Blood From Patients With Familial Dysautonomia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Familial dysautonomia (FD) is a hereditary neurodevelopmental disorder caused by aberrant splicing of the ELP1 gene, leading to a tissue‐specific reduction in ELP1 protein expression. Preclinical models indicate that increasing ELP1 levels can mitigate disease manifestations.

The spatial distribution in infinite dimensional spaces and related quantiles and depths

open access: yes, 2014
The spatial distribution has been widely used to develop various nonparametric procedures for finite dimensional multivariate data. In this paper, we investigate the concept of spatial distribution for data in infinite dimensional Banach spaces.
