Proactive Serving Decreases User Delay Exponentially: The Light-Tailed Service Time Case

open access: yesIEEE/ACM Transactions on Networking, 2017
In online service systems, the delay experienced by users from service request to service completion is one of the most critical performance metrics. To improve user delay experience, recent industrial practices suggest a modern system design mechanism: proactive serving , where the service system predicts future user requests and allocates its ...

Quantitative proteomic analysis reveals different characteristics of bladder cancer cells after exposure to bisphenol A

open access: yesFEBS Open Bio, EarlyView.
Bisphenol A (BPA), a common chemical in plastics, exerts dual effects on bladder cancer cells: low doses promote growth and migration, while high doses suppress growth and migration. Multi‐omics and bioinformatics reveal BPA acts via MAPK and inflammatory pathways.

Two-Stage Dynamics of In Vivo Bacteriophage Genome Ejection

open access: yesPhysical Review X, 2018
Biopolymer translocation is a key step in viral infection processes. The transfer of information-encoding genomes allows viruses to reprogram the cell fate of their hosts. Constituting 96% of all known bacterial viruses [A. Fokine and M. G.

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

open access: yesFEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Adaptive Emergence Patterns of Spot‐Tailed Earless Lizards: Influence of UV Light and Temperature on Diel Activity

open access: yesEcology and Evolution
We examined the emergence behavior of spot‐tailed earless lizards (STEL; Holbrookia lacerata and H. subcaudalis). Using controlled laboratory and seminatural experiments, we evaluated the effects of UV light, visible light, temperature, and prey activity

Combined 5‐aminolevulinic acid and ferric ammonium citrate treatment promotes hair follicle growth by activating dermal papilla cells

open access: yesFEBS Open Bio, EarlyView.
5‐Aminolevulinic acid combined with ferric ammonium citrate (5‐ALA/FAC) stimulates dermal papilla cell activity and promotes hair follicle growth. The treatment enhances ERK and AKT signaling, increases hair‐inductive gene expression, and restores dermal papilla function suppressed by dihydrotestosterone and oxidative stress, resulting in enhanced hair

Breeding latitude predicts timing but not rate of spring migration in a widespread migratory bird in South America

open access: yesEcology and Evolution, 2019
Identifying the processes that determine avian migratory strategies in different environmental contexts is imperative to understanding the constraints to survival and reproduction faced by migratory birds across the planet.

Large deviations for light-tailed Lévy bridges on short time scales

open access: yes
Let $L = (L(t))_{t\geq 0}$ be a multivariate Lévy process with Lévy measure $ν(dy) = \exp(-f(|y|)) dy$ for a smoothly regularly varying function $f$ of index $α>1$. The process $L$ is renormalized as $X^\varepsilon(t) = \varepsilon L(r_\varepsilon t)$, $t\in [0, T]$, for a scaling parameter $r_\varepsilon= o(\varepsilon^{-1})$, as $\varepsilon \to 0$

Visual Recovery Reflects Cortical MeCP2 Sensitivity in Rett Syndrome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Rett syndrome (RTT) is a devastating neurodevelopmental disorder with developmental regression affecting motor, sensory, and cognitive functions. Sensory disruptions contribute to the complex behavioral and cognitive difficulties and represent an important target for therapeutic interventions.

Does intensive goose grazing affect breeding waders?

open access: yesEcology and Evolution, 2019
Increasing goose population sizes gives rise to conflicts with human socioeconomic interests and in some circumstances conservation interests. Grazing by high abundances of geese in grasslands is postulated to lead to a very short and homogeneous sward ...
