Assessing the potential of ionosonde for forecasting post-sunset equatorial spread F: an observational experiment in Southeast Asia

Earth, Planets and Space, 2023
The occurrence of equatorial spread F (ESF) has the potential to detrimentally impact space-based technological systems. This study investigates the utility of ionosondes in forecasting the incidence of post-sunset ESF in the zonal direction, utilizing ...

Development of composite electrospun films utilizing soy protein amyloid fibrils and pullulan for food packaging applications

Food Chemistry: X, 2023
Electrospun films (ESF) are gaining attention for active delivery due to their biocompatibility and biodegradability. This study investigated the impact of adding soy protein amyloid fibrils (SAFs) to ESF.

Bypassing Heteronuclear MRI: Metal-Free Organosilicon Nanotracers for Background-Free Hotspot ¹H Imaging on Clinical Hardware. [PDF]

Adv Sci (Weinh)
Organosilicon micelles enable background‐free molecular magnetic resonance imaging (MRI) while remaining fully compatible with standard proton (1H) hardware. By exploiting a spectrally silent 1H window at ∼0 ppm, the silicone nanotracer allows hotspot detection by 1H chemical‐shift imaging (CSI) without metals or heteronuclei, enabling direct overlay ...

A mechanistic kinetic description of lactate dehydrogenase elucidating cancer diagnosis and inhibitor evaluation

Journal of Enzyme Inhibition and Medicinal Chemistry, 2017
As a key enzyme for glycolysis, lactate dehydrogenase (LDH) remains as a topic of great interest in cancer study. Though a number of kinetic models have been applied to describe the dynamic behavior of LDH, few can reflect its actual mechanism, making it

Conservation potential of prescribed fire for maintaining habitats and populations of an endangered rattlesnake Sistrurus c. catenatus

Endangered Species Research, 2013
Many endangered species rely on early successional habitats to complete parts of their life cycles. We examined whether prescribed fire can be used to aid in conservation of the endangered eastern massasauga rattlesnake Sistrurus catenatus catenatus Raf.

The Selective Inactivation of an ESF-Generating Factor (EGF) in the Presence of Erythropoietin (ESF)

Experimental Biology and Medicine, 1971
SummaryAn ESF-generating factor (EGF), erythropoietin (ESF) and a mixture of both were incubated with dithiothreitol (DTT, a protective reagent for sulfhydryl groups). Ten μM DTT completely prevented the production of 0.26 ± 0.01 IU of ESF by EGF but did not inactivate ESF.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

Advanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.
