Detecting Critical Change in Dynamics Through Outlier Detection with Time‐Varying Parameters

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Intensive longitudinal data are often found to be non‐stationary, namely, showing changes in statistical properties, such as means and variance‐covariance structures, over time. One way to accommodate non‐stationarity is to specify key parameters that show over‐time changes as time‐varying parameters (TVPs). However, the nature and dynamics of

Winter‐active spiders (Clubiona) have a hyperactive antifreeze protein with a unique beta‐solenoid fold

open access: yesThe FEBS Journal, EarlyView.
Antifreeze proteins from winter‐active spiders were purified using their affinity for ice. After LC–MSMS characterization, corresponding transcripts were identified. The antifreeze protein folds as a β‐solenoid with a large flat ice‐binding site on one surface and can bind to ice crystals and prevent their growth at −4 °C.

Standing on a common ground: a comparison of static stability approaches for pallet loading

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract At the practical level, the static stability constraint is one of the most important constraints in practical pallet loading problems, such as air cargo palletizing. Approaches to modeling static stability, which range from base support and mechanical equilibrium calculations to physical simulation, differ in workflow, focus, and assumptions ...

Crustal Accretion, Significant Mantle Uplift, and Exhumation along Non-transform Discontinuities: Equatorial Mid-Atlantic Ridge (7º 10’ – 0º 50’ N)

open access: yesBrazilian Journal of Geophysics
The exhumation and exposure of mantle rocks is a common process that takes place during the tectono-magmatic evolution of a newly created lithosphere along slow- and ultraslow-spreading oceanic ridges, such as the Equatorial Mid-Atlantic Ridge.

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

open access: yesMedical and Veterinary Entomology, EarlyView.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.

CMB Telescopes and Optical Systems

open access: yes, 2012
The cosmic microwave background radiation (CMB) is now firmly established as a fundamental and essential probe of the geometry, constituents, and birth of the Universe. The CMB is a potent observable because it can be measured with precision and accuracy.

Interspecific facilitation, elevation, and site influence survival and growth for intertidal Ostrea angasi restoration

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction The flat oyster Ostrea angasi previously formed extensive reefs throughout temperate regions of Australia. These reefs were overharvested and destroyed after European colonization and have been functionally extinct for >150 years. While large‐scale subtidal O.

A systematic color correction pipeline for controlled‐environment imaging

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
ABSTRACT We present a stepwise color correction (CC) pipeline for controlled imaging environments. The workflow integrates flat‐field correction (FFC), gamma correction, and white‐balance correction, followed by a color‐mapping (CM) stage using machine‐learning regression—linear, partial least squares, and neural networks (NNs)—to deliver reliable CC ...

Application of formal optimization techniques in thermal/structural design of a heat-pipe-cooled panel for a hypersonic vehicle [PDF]

open access: yes
Nonlinear mathematical programming methods are used to design a radiantly cooled and heat-pipe-cooled panel for a Mach 6.7 transport. The cooled portion of the panel is a hybrid heat-pipe/actively cooled design which uses heat pipes to transport the ...
