    Variability of Reaction Time as a Marker of Executive Function Impairments in Fibromyalgia by Stefan Duschek, Cristina Muñoz Ladrón de Guevara, María José Fernández Serrano, Casandra I. Montoro, Santiago Pelegrina López, Gustavo A. Reyes del Paso

    Published 2022-01-01
    “…Performance was indexed by the hit rate, false alarm rate, and mean (M) and intraindividual standard deviation (SD) of RT and the ex-Gaussian parameters mu, sigma, and tau. Mu and sigma indicate the M and SD of the Gaussian distribution; tau reflects the M and SD of the exponential function. …”

    Searching for the cellular underpinnings of the selective vulnerability to tauopathic insults in Alzheimer’s disease by Justin Torok, Pedro D. Maia, Chaitali Anand, Ashish Raj

    Published 2025-02-01
    “…Further, cell-type distributions were more predictive of end-time-point tau pathology than AD-risk-gene expression. Using gene ontology analysis, we found that the genes that are directly correlated to tau pathology are functionally distinct from those that constitutively embody the vulnerable cells. …”

    Constraints on the Nonstandard Interaction in Propagation from Atmospheric Neutrinos by Shinya Fukasawa, Osamu Yasuda

    Published 2015-01-01
    “…The sensitivity of the atmospheric neutrino experiments to the nonstandard flavor-dependent interaction in neutrino propagation is studied under the assumption that only nonvanishing components of the nonstandard matter effect are the electron and tau neutrino components ϵee, and ϵeτ, ϵττ and that the tau-tau component satisfies the constraint ϵττ=|ϵeτ|2/(1+ϵee) which is suggested from the high energy behavior for atmospheric neutrino data. …”

    Bender–Knuth Billiards in Coxeter Groups by Grant Barkley, Colin Defant, Eliot Hodges, Noah Kravitz, Mitchell Lee

    Published 2025-01-01
    “…Given a Coxeter element $c=s_{i_n}\cdots s_{i_1}$ , we consider the operator $\mathrm {Pro}_c=\tau _{i_n}\cdots \tau _{i_1}$ . We say W is futuristic if for every nonempty finite convex set $\mathscr {L}$ , every Coxeter element c and every $u\in W$ , there exists an integer $K\geq 0$ such that $\mathrm {Pro}_c^K(u)\in \mathscr {L}$ . …”

    On the basic reproduction number $R_0$ in sexual activity models for HIV/AIDS epidemics: Example from Yunnan, China by Nicolas Bacaër, Xamxinur Abdurahman, Jianli Ye, Pierre Auger

    Published 2007-07-01
    “…In the present paper, we notice that this theoretical distribution is different from the one obtained in behavioral surveys for the number of sexual partnerships over a period of length $\tau$. The latter is a ''mixed Poisson distribution'' whose mean $m$ and variance $v$ are such that $M=m/\tau$ and $V=(v-m)/\tau^2$. …”

    Stability, delay, and chaotic behavior in a Lotka-Volterra predator-prey system by S. Nakaoka, Y. Saito, Y. Takeuchi

    Published 2005-10-01
    “…We consider the following Lotka-Volterra predator-prey system with two delays:$x'(t) = x(t) [r_1 - ax(t- \tau_1) - by(t)]$$y'(t) = y(t) [-r_2 + cx(t) - dy(t- \tau_2)]$ (E)We show that a positive equilibrium of system (E) is globally asymptotically stable for small delays. …”
