The Molecular Basis of Amino Acids Sensing

open access: yesAdvanced Science, EarlyView.
Amino acids are essential as protein building blocks and signaling molecules, enabling metabolic regulation. Cells sense amino acid levels to control protein synthesis, maintain homeostasis, and adapt to nutritional changes. This review explores recent advances in amino acid sensing mechanisms across organisms, highlighting their roles in cellular ...

Spring and Power in Hovering Ornithopters

open access: yesAdvanced Intelligent Systems, EarlyView.
Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

How to Argue for Pragmatic Encroachment [PDF]

open access: yes, 2018
Purists think that changes in our practical interests can’t affect what we know unless those changes are truth-relevant with respect to the propositions in question. Impurists disagree.

Sharpening our understanding of saber‐tooth biomechanics

open access: yesThe Anatomical Record, EarlyView.
Abstract Saber‐teeth are a striking example of convergent evolution in vertebrate predators, having evolved multiple times in mammals and their early ancestors. While there is broad consensus that saber‐toothed taxa employed a distinct biting strategy compared to conical‐toothed carnivores, like the lion, the precise mechanics and variability of this ...

Electrocution of raptors at power lines in Central Kazakhstan [PDF]

open access: yes, 2013
Along three transects of medium voltage power lines in the steppe of Central Kazakhstan, surveys for bird casualties were carried out in summer 2006 in order to estimate the quantitative and qualitative impact of power lines on bird mortality in this ...

A simple approach to biophysical profiling of blood cells in extranodal NK/T cell lymphoma patients using deep learning‐integrated image cytometry

open access: yesBMEMat, EarlyView.
We developed a deep learning‐integrated image cytometry technique to profile biophysical attributes of blood cells from ENKTL patients. We demonstrate specific changes in cell size, eccentricity, and refractive index during treatment in a label‐free manner.

Verification of Information Flow Properties under Rational Observation [PDF]

open access: yes, 2014
Information flow properties express the capability for an agent to infer information about secret behaviours of a partially observable system. In a language-theoretic setting, where the system behaviour is described by a language, we define the class of ...

Metabolism study of 3‐chloromethcathinone (3‐CMC) by dried blood spot (DBS) sampling after controlled administration using a murine model

open access: yesDrug Testing and Analysis, EarlyView.
The metabolism of 3‐chloromethcathinone (3‐CMC) was studied after controlled administration in a murine model using the dried blood spot (DBS) technique for the sampling, storage and purification of blood samples. The metabolite profile of 3‐CMC was studied by LC‐HRMS, while the stability of 3‐CMC and its three identified metabolites was also assessed ...

Rapid and Effective Determination of Ethyl Glucuronide in Hair by Micro Extraction by Packed Sorbent (MEPS) and LC‐MS/MS

open access: yesDrug Testing and Analysis, EarlyView.
The development and validation of a MEPS method for the purification of hair extract for the EtG determination and quantification in the keratin matrix is the main focus of this study. The method is fast and effective and, as a miniaturised technique, requires only small amounts of solvent.
