Rapid and Ultra‐Sensitive SARS‐CoV‐2 Subgenomic RNA Detection Using Single‐Molecule With a Large Transistor‐SiMoT Bioelectronic Platform

open access: yesAdvanced Electronic Materials, EarlyView.
The single‐molecule with a large transistor‐SiMoT is proposed for the detection of the subgenomic RNA of SARS‐CoV‐2, achieving a diagnostic sensitivity of 98.0% and a specificity of 87.8%. The SiMoT technology, currently at TRL‐5, is suitable for point‐of‐care settings and delivers the result to the end user in 30 min.

Predator–Prey Behavior of Droplets Propelling Through Self‐Generated Channels in Crystalline Surfactant Layers

open access: yesAngewandte Chemie, EarlyView.
A crystalline layer is formed by an amphiphilic decylamine surfactant at the air/water interface. Aldehyde‐containing ester oil droplets self‐propel by consuming amines from the crystalline layer, thereby generating open channels along which myelin‐forming amphiphile droplets chase and ultimately catch the aldehyde droplets in a predator–prey analogy ...

Diversity and Abundance of Natural Enemies of Helopeltis antonii in Cocoa Plantation Related with Plant Pattern and Insecticide Application

open access: yesCoffee and Cocoa Research Journal, 2017
Natural enemy is an important factor in management of cacao pests. One way to increase its diversity and abundance is through agroecosystem management techniques that support.

Dynamical behavior of Predator-Prey with Allee Effect on Both Populations and Disease in Predator [PDF]

open access: yesarXiv
In the current study, we took into account a model of nonlinear ``predator-prey'' interactions including the ``Allee effect'' on both populations and disease in the predator population. The population as a whole is split into three: the prey population, susceptible predator, and diseased predator. The ``Takagi-Sugeno (T-S) impulsive control model'' and

The Impacts of Health and Environmental Information Nudges on Meat Choices: Where Does Goat Meat Fit?

open access: yesAgribusiness, EarlyView.
ABSTRACT Amidst a recent surge in US goat meat imports to meet growing demand, this study contributes to the meat demand literature by examining consumer preferences for goat meat, a relatively healthy and environmentally friendly alternative to other popular meats.

Comments on "Critical Study on the Absorbing Phase Transition in a Four-State Predator-Prey Model in One Dimension" [PDF]

open access: yesarXiv, 2011
In a recent article [arXiv:1108.5127] Park has shown that the four-state predator-prey model studied earlier in [J. Stat. Mech, L05001 (2011)] belongs to Directed Percolation (DP) universality class. It was claimed that predator density is not a reasonable order parameter, as there are many absorbing states; a suitably chosen order parameter shows DP ...
