Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

open access: yesFEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

INDIRECT SAMPLING in the CONTEXT of DUAL FRAME SURVEYS [PDF]

open access: yes
Under-coverage is one of the most common problems of sampling frames. To reduce the impact of coverage error on survey estimates several frames can be combined in order to achieve a complete (or nearly complete) coverage of the target population ...

Inhabiting the Epistemic Frame of Mind: Plato's Protagoras and the Socratic Denial of Akrasia [PDF]

open access: yes, 2006
Socrates is said to have thought that what is responsible for seeming cases of akrasia is ignorance. He also seems to have freed himself, in his own life, from the distinctive kind of inner resistance that plagues the akratic.

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

open access: yesFEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

Evaluation of Cross-Coupling Decoupling in Islanded Microgrid Control with Inductor Current Feed-Forward Technique

open access: yesJurnal EECCIS (Electrics, Electronics, Communications, Controls, Informatics, Systems)
To control the voltage source inverter in an islanded microgrid, the d-q reference frame is employed chiefly because of its ability to model inverter's dynamic models accurately.

Time-dependent bag of words on manifolds for geodesic-based classification of video activities towards assisted living and healthcare

open access: yesEURASIP Journal on Image and Video Processing, 2017
In this paper, we address the problem of classifying activities of daily living (ADL) in video. The basic idea of the proposed method is to treat each human activity in the video as a temporal sequence of points on a Riemannian manifold and classify such

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

MiR‐513a promotes human erythroid differentiation by modulating c‐Jun

open access: yesFEBS Open Bio, EarlyView.
During early human erythropoiesis, miR‐513a promoted erythroid differentiation in primary human CD34+ hematopoietic stem‐progenitor cells and human TF‐1 erythroleukemic cells by indirectly decreasing c‐Jun and phospho‐c‐Jun expression, which are associated with increased GATA1 expression.
