Habitual Cross-legged Sitting Increases Lumbopelvic Rotation Asymmetry

Physical Therapy Korea
Background: Cross-legged sitting posture (CLSP) is common in daily life but may cause asymmetrical loading of the pelvis and spine, potentially leading to postural imbalance and musculoskeletal problems.

Convergence Properties of an Extended Least Squares (ELS) Variant [PDF]

Modeling, Identification and Control, 2000
By factorizing the A- and B-polynomials in an ARMAX model and filtering the input/output data with the appropriate factors thereof, the parameters of the model can be estimated in a decentralized fashion.

Local Convergence Analysis of FastICA

, 2006
The FastICA algorithm can be considered as a selfmap on a manifold. It turns out that FastICA is a scalar shifted version of an algorithm recently proposed. We put these algorithms into a dynamical system framework. The local convergence properties are investigated subject to an ideal ICA model.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Comparison of the Pelvic Rotation Angle During Hip Lateral Rotation in the Standing and Prone Positions in Participants With and Without Tensor Fasciae Latae/Iliotibial Tract Tightness

Physical Therapy Korea
Background: Tensor fasciae latae (TFL) and iliotibial tract (ITB) tightness can pull the pelvis during hip lateral rotation (HLR), increasing pelvic rotation due to muscle tension.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Convergence analysis for nonlinear GMRES

IMA Journal of Numerical Analysis
Abstract In this work we revisit nonlinear generalized minimal residual method (NGMRES) applied to nonlinear problems. NGMRES is used to accelerate the convergence of fixed-point iterations, which can substantially improve the performance of the underlying fixed-point iterations.
