Asymptomatic Idiopathic Renal Infarction Detected Incidentally on Contrast-Enhanced Computed Tomography: A Case Report

open access: yesMedicina, 2023
Background: Renal infarction is an extremely rare disease. Although more than 95% of cases are symptomatic, there have been no previously reported asymptomatic cases, without any abnormal blood and urine test findings.

Discrimination, Acculturation, Acculturative Stress, and Latino Psychological Distress: A Moderated-Mediational Model [PDF]

open access: yes, 2012
Prior research has found that perceived discrimination is associated with adverse mental health outcomes among Latinos. However, the process by which this relationship occurs remains an understudied area.

Effects of the number of periods on strain in superlattices [PDF]

open access: yes, 2002
The effect of periods on the accumulation and release of stress in GaAs/AlInAs superlattices structure is reported here. It is observed that in GaAs/AlInAs superlattices, when the Indium (In) content is greater than 10%, stress accumulates monotonically ...

Fairness, Adverse Selection, and Employment Contracts [PDF]

open access: yes, 2005
This paper considers a firm whose potential employees have private information on both their productivity and the extent of their fairness concerns. Fairness is modelled as inequity aversion, where fair-minded workers suffer if their colleagues get more ...

Elastic electron scattering by laser-excited 138Ba( ... 6s6p 1P1) atoms [PDF]

open access: yes, 1998
The results of a joint experimental and theoretical study concerning elastic electron scattering by laser-excited 138Ba( ... 6s6p 1P1) atoms are described. These studies demonstrate several important aspects of elastic electron collisions with coherently

Forecasting High-Dimensional Covariance Matrices Using High-Dimensional Principal Component Analysis

open access: yesAxioms, 2022
We modify the recently proposed forecasting model of high-dimensional covariance matrices (HDCM) of asset returns using high-dimensional principal component analysis (PCA).

Mixed-Valent Trinuclear CoIII-CoII-CoIII Complex with 1,3-Bis(5-chlorosalicylideneamino)-2-propanol

open access: yesMolecules, 2022
A mixed-valent trinuclear complex with 1,3-bis(5-chlorosalicylideneamino)-2-propanol (H3clsalpr) was synthesized, and the crystal structure was determined by the single-crystal X-ray diffraction method at 90 K.

Improved approximation guarantees for weighted matching in the semi-streaming model [PDF]

open access: yes, 2009
We study the maximum weight matching problem in the semi-streaming model, and improve on the currently best one-pass algorithm due to Zelke (Proc. of STACS2008, pages 669-680) by devising a deterministic approach whose performance guarantee is 4.91 ...

Systematic first-principles calculations of charge transfer transitions of transition metal ions (Sc3+, Ti3+, V3+, Cr3+, Mn3+, Fe3+) in α-Al2O3

open access: yesOptical Materials: X, 2019
In order to predict the LMCT energies for various trivalent transition metal (TM) ions in α-Al2O3 nonempirically, we performed first-principles calculations using TMO69− cluster (TM = Sc3+, Ti3+, V3+, Cr3+, Mn3+, Fe3+) using the Discrete Variational ...
