FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

A study on the impact Soil degree of Compactness on Soil Physical Quality index for Soils with varying gypsum content [PDF]
Tikrit Journal for Agricultural SciencesLaboratory experiments were conducted to study the impact of soil compaction degree (DC%) defined as the ratio between natural bulk density (BD natural) and critical bulk density (BD critical) on Soil Physical Quality index (S-index) for seven soil ...

Using copulas to construct bivariate foreign exchange distributions with an application to the sterling exchange rate index (revised) [PDF]
, 2005 We model the joint risk neutral distribution of the euro-sterling and the dollar-sterling exchange rates using option-implied marginal distributions that are connected via a copula function that satisfies the triangular no-arbitrage condition.

Abstract The most widely accepted and historically used predictor of the fouling potential of reverse osmosis feedwater is the plugging factor (PF), now commonly known as the Silt Density Index (SDI). The SDI procedure was standardized by ASTM International and is intended to be used as a measure of the fouling capacity of feedwater to ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The Generalized Extreme Value (GEV) Distribution, Implied Tail Index and Option Pricing [PDF]
Crisis events such as the 1987 stock market crash, the Asian Crisis and the bursting of the Dot-Com bubble have radically changed the view that extreme events in financial markets have negligible probability.

Adjusted empirical likelihood estimation of the youden index and associated threshold for the bigamma model [PDF]
, 2009 The Youden index is a widely used measure in the framework of medical diagnostic, where the effectiveness of a biomarker (screening marker or predictor) for classifying a disease status is studied.

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Body mass index: a measure of fatness or leanness?
, 1995 The relationship between body fat and stature-adjusted weight indices was explored. Assuming the term height’ is a valid indicator of a subject’s lean body mass, heighplweight was shown to be an accurate measure of percentage lean body mass and, as such,
