Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

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 ...

Spatio-Spectral Structure Tensor Total Variation for Hyperspectral Image Denoising and Destriping

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article proposes a novel regularization method, named spatio-spectral structure tensor total variation (${\text{S}_{3} \text{TTV}}$), for denoising and destriping hyperspectral (HS) images.

Sensory trait variation in an echolocating bat suggests roles for both selection and plasticity [PDF]

, 2014
Background: Across heterogeneous environments selection and gene flow interact to influence the rate and extent of adaptive trait evolution. This complex relationship is further influenced by the rarely considered role of phenotypic plasticity in the ...

Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Temporal variation in genetic diversity and population structure of Burlina cattle breed

Italian Journal of Animal Science, 2014
We analysed the temporal variation of inbreeding, genetic variability and population structure in the Burlina (BUR) cattle breed. A total of 279 individuals were chosen for the analysis representing a period of 19 years (1991-2010) and analysed using 24 ...

Dialectal variation in german 3-verb clusters : a surface-oriented optimality theoretic account [PDF]

, 2004
We present data from an empirical investigation on the dialectal variation in the syntax of German 3-verb clusters, consisting of a temporal auxiliary, a modal verb, and a predicative verb. The ordering possibilities vary greatly among the dialects. Some
