Membrane-Spanning Molecular Lengths as an Agnostic Biosignature

Astrobiology
We explore a hypothesis in which the detection of classes of lipid-like molecules with similar abundance-averaged lengths would constitute a biosignature for other worlds. This is based on the functional requirements of membrane molecules: they must have enough hydrophobic length to not diffuse away from the membrane, be capped by one or two ...

Noisy signals: Does rating volatility depend on the length of the consumption span?

Economic Modelling, 2023
This paper investigates the informational content of online reviews. For the case of hotels, we model how the length of the stay shapes the variance of review scores. Grounded on violations of temporal monotonicity, errors in recall and hedonic adaptation theories, we first present a characterization of how the consumption span affects the non ...

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Prevalence of Two-Syllable Digits Affecting Forward Digit Span Test Score

SAGE Open, 2016
The word length effect shows a connection between word length and working memory performance. Although the relationship between digit verbal length and digit span has been investigated between languages, it has not been investigated within a language. It

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Fatigue Life Prediction of Submarine Pipelines with Varying Span Length and Position

Journal of Marine Science and Engineering
Free spans of submarine pipelines are prone to be subjected to vortex-induced vibration (VIV) under the action of currents, leading to fatigue damage of submarine pipelines.

Traffic Load Models for Latvian Road Bridges With Span Length up to 30 Meters

The Baltic Journal of Road and Bridge Engineering, 2014
Bridges are structures that propose the service life up to hundred years. However, the actual traffic load models significantly differ from the characteristic load models used in the design. The analysis of former design codes of bridges used in the last

Networks of Recurrent Events, a Theory of Records, and an Application to Finding Causal Signatures in Seismicity [PDF]

, 2007
We propose a method to search for signs of causal structure in spatiotemporal data making minimal a priori assumptions about the underlying dynamics. To this end, we generalize the elementary concept of recurrence for a point process in time to recurrent

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Effect of using different configurations of NSM-CFRP strips on the flexural strength of RC beams [PDF]

MATEC Web of Conferences
The main objective of this research is to study, experimentally, the flexural strength of lightweight reinforced concrete (LWRC) beams strengthened using the near-surface mounted carbon fiber reinforced polymer technique (NSM-CFRP). Four simply supported
