Inner Language Form as a Determinant of its Lexical Peculiarity (based on the Study Material of the Russian and the Teleut Languages Paroemia)

RUDN Journal of Language Studies, Semiotics and Semantics, 2019
In the present article we make an effort to develop the ideas of the Russian linguist G.P. Melnikov about the determinants of the language system in the context of his study about the dynamic language nature.

Determinism and non-determinism in PDL

Theoretical Computer Science, 1991
In a previous paper of the author it is proven that if we add the iteration to SPDL (strict propositional dynamic logic) then the new system has the same expressive power as PDL (propositional dynamic logic). Under review the case of nondeterminism is studied.

Determinants of menarche [PDF]

Reproductive Biology and Endocrinology, 2010
Menarche is a milestone in a woman's life as it denotes the start of reproductive capacity. Aim of this report is to review the recent developments and the current knowledge in the neuroendocrinology of pubertal onset and the factors, genetic and environmental, that influence menarcheal age.

Making tau amyloid models in vitro: a crucial and underestimated challenge

FEBS Letters, EarlyView.
This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

Abstract Harmonic Analysis on the General Linear Group GL(n,R) [PDF]

, 2014
Consider the general linear group, which is not connected but rather has two connected components, the matrices with positive determinant and the ones with negative determinant. Consider the Iwasawa decomposition of its special linear group. We adopt the

The Mayans: Climate determinism or geomagnetic determinism? [PDF]

Eos, Transactions American Geophysical Union, 2007
Climatic variations since the end of the last ice age have been large enough to influence the fate of ancient civilizations, and deciphering the exact role of climate in the history of old societies is an active and challenging domain of research [e.g., deMenocal, 2001]. This potential influence, which serves as the foundation of ‘climate determinism,’

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

FEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

A stepwise emergence of evolution in the RNA world

FEBS Letters, EarlyView.
How did biological evolution emerge from chemical reactions? This perspective proposes a gradual scenario of self‐organization among RNA molecules, where catalytic feedback on random mixtures plays the central role. Short oligomers cross‐ligate, and self‐assembly enables heritable variations. An event of template‐externalization marks the transition to

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

FEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
