Rounding theory and method for the pitch curves of the variable center distance non-circular gear pair based on working conditions

open access: yesAdvances in Mechanical Engineering
Based on the working conditions of the variable center distance non-circular gear pair, this research provides the rounding theories and methods for the theoretical pitch curves of the gear pair, including establish the working conditions model of the ...

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

open access: yesFEBS 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.

Social context prevents heat hormetic effects against mutagens during fish development

open access: yesFEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

Analysis of Semantic Categories in Turkish According to Prototype Theory

open access: yesAnkara Üniversitesi Dil ve Tarih-Coğrafya Fakültesi Dergisi, 2017
Rosch’s prototype theory is a cognition-based categorization theory which was born as a reaction to Aristotelian view of categorization which has been acknowledged for centuries. Contrary to the Aristotelian view, Rosch claimed that internal structure of

The Academic Medical Center Linear Disability Score (ALDS) item bank: item response theory analysis in a mixed patient population

open access: yesHealth and Quality of Life Outcomes, 2005
Background Currently, there is a lot of interest in the flexible framework offered by item banks for measuring patient relevant outcomes. However, there are few item banks, which have been developed to quantify functional status, as expressed by the ...

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

open access: yesFEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...

Homotopy and duality in non-Abelian lattice gauge theory

open access: yes, 2003
We propose an approach of lattice gauge theory based on a homotopic interpretation of its degrees of freedom. The basic idea is to dress the plaquettes of the lattice to view them as elementary homotopies between nearby paths.

Contributions to inflation after euro adoption: the case of Central and Eastern European countries

open access: yesEkonomia i Prawo, 2020
Motivation: Based on theory, the introduction of a single currency should cause a decrease in transaction costs, which in effect should lead to a drop in consumer prices.

Brucella NyxA and NyxB dimerization enhances effector function during infection

open access: yesFEBS Letters, EarlyView.
Brucella abortus thrives inside cells thanks to the translocation of effector proteins that fine‐tune cellular functions. NyxA and NyxB are two effectors that destabilize the nucleolar localization of their host target, SENP3. We show that the Nyx proteins directly interact with each other and that their dimerization is essential for their function ...
