Modeling Cylindrical Inhomogeneity of Finite Length with Steigmann–Ogden Interface

Technologies, 2020
A mathematical model employing the concept of energy-equivalent inhomogeneity is applied to analyze short cylindrical fiber composites with interfaces described by the Steigmann–Ogden material surface model.

A refinement of Wilf-equivalence for patterns of length 4

Journal of Combinatorial Theory, Series A, 2014
In their paper \cite{DokosDwyer:Permutat12}, Dokos et al. conjecture that the major index statistic is equidistributed among 1423-avoiding, 2413-avoiding, and 2314-avoiding permutations. In this paper we confirm this conjecture by constructing two major index preserving bijections, $Θ:S_n(1423)\to S_n(2413)$ and $Ω:S_n(2314)\to S_n(2413)$.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Small RNA pathways in mammalian oocytes

FEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Elementary group equivalence with the integral length function

Illinois Journal of Mathematics, 1986
The main concern of this paper is the elementary equivalence of classes of free groups with operators and free products with a length function. They use a number of results about free groups, free products and free operator groups, and results about multi-base models, partial isomorphisms and elementary equivalence, \(\omega\)-isomorphism and regular ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

Myopi-X lenses vs. low-dose atropine in myopia control: a Turkish retrospective study

BMC Ophthalmology
Background The global prevalence of myopia is rising rapidly, with projections indicating that by 2050, half of the world’s population will be affected. High myopia is associated with an increased risk of sight-threatening complications, contributing to ...

Gait Analysis of Quadruped Robot Using the Equivalent Mechanism Concept Based on Metamorphosis

Chinese Journal of Mechanical Engineering, 2019
The previous research regarding the gait planning of quadruped robot focuses on the sequence for lifting off and placing the feet, but neglects the influence of body height. However, body height affects gait performance significantly, such as in terms of

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

Graduated atropine protocol effects on spherical equivalent and axial length in premyopic children

Scientific Reports
We evaluated the effects of a graduated-concentration atropine protocol on the progression of myopia in premyopic Korean children. This retrospective study included 64 premyopic children with an initial spherical equivalent (SE) between + 0.75 diopters ...
