Anisotropic electron g-factor in quantum dots with spin-orbit interaction

open access: yes, 2004
g-factor tuning of electrons in quantum dots is studied as function of in-plane and perpendicular magnetic fields for different confinements. Rashba and Dresselhaus effects are considered, and comparison is made between wide- and narrow-gap materials ...

La religiosidad como búsqueda y su relación con la orientación intrínseca y extrínseca [PDF]

open access: yes, 2013
Allport and Ross (1967) originally developed the religious orientation concept, identifying two types: intrinsic and extrinsic orientation. Later, Batson (1976) conceptualized a third type: the quest orientation, measured by the unidimensional Quest ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Factor XII (Hageman Factor) Deficiency: a rare harbinger of life threatening complications

open access: yesThe Pan African Medical Journal, 2019
Hageman factor (factor XII) has a key role in activation of intrinsic coagulation system gauged by activated partial thromboplastin time (aPPT)).

Consistency of Bayes factor for nonnested model selection when the model dimension grows

open access: yes, 2016
Zellner's $g$-prior is a popular prior choice for the model selection problems in the context of normal regression models. Wang and Sun [J. Statist. Plann.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Masked vitamin B12 deficiency in pernicious anaemia: A diagnostic trap due to assay interference—Case report

open access: yesSAGE Open Medical Case Reports
Megaloblastic anaemia is mainly caused by vitamin B12 or folate deficiency. However, rare cases present with discordant laboratory findings, particularly falsely elevated vitamin B12 levels due to assay interference from anti-intrinsic factor antibodies,

Consistency of Bayesian procedures for variable selection

open access: yes, 2009
It has long been known that for the comparison of pairwise nested models, a decision based on the Bayes factor produces a consistent model selector (in the frequentist sense).
