Dual Disruption of the Immune Cytokine Spätzle Facilitates Fungal Infection of Diverse Insect Hosts

open access: yesAdvanced Science, EarlyView.
The Toll pathway is essential for insect defense against fungal pathogens. This works reports that fungal parasites employ two divergent virulent effectors to target the Toll receptor ligand Spätzle: a metalloprotease degrading it and a hairpin‐like effector hijacking it to block signal transduction. This dual strategy enables the fungus to kill a wide

Stability and effective masses of composite-fermions in the first and second Landau Level

open access: yes, 1994
We propose a measure of the stability of composite fermions (CF's) at even-denominator Landau-level filling fractions. Assuming Landau-level mixing effects are not strong, we show that the CF liquid at $\nu=2+1/2$ in the $n=1$ Landau level cannot exist ...

Hot‐Pressing Annealing‐Induced Light Utilization Enhancement and Crystallinity Optimization Enable High‐Performance Narrowband Ultraviolet Photodetectors for Real‐Time Ultraviolet Radiation Monitors

open access: yesAdvanced Science, EarlyView.
By utilizing a hot‐pressing (HP) annealing strategy, Cs3Cu2I5 films with larger grains vertically spanning the entire thickness are fabricated. Because HP annealing enhances light utilization and charge transport in Cs3Cu2I5/GaN heterojunction, the HP device achieves superior detection performance while maintaining narrowband photoresponse to UVA/UVB ...

Enhanced Protein Synthesis and Hippocampus‐Dependent Memory via Inhibition of YTHDF2‐Mediated m6A mRNA Degradation

open access: yesAdvanced Science, EarlyView.
YTHDF2‐mediated m6A mRNA decay critically regulates learning and memory. Its forebrain‐specific knockout in mice impedes degradation of m6A‐modified mRNAs, enhancing hippocampal synaptic transmission, protein synthesis, and memory. Conversely, hippocampal YTHDF2 reintroduction or SEMA4B reduction reverses this enhancement, while its overexpression ...

Escaping from nonhyperbolic chaotic attractors

open access: yes, 2004
We study the noise-induced escape process from chaotic attractors in nonhyperbolic systems. We provide a general mechanism of escape in the low noise limit, employing the theory of large fluctuations.

Gold Nanoturf‐Mediated Wireless Photothermal Upregulation of Human Adipose‐Derived Stem Cell Spheroids for Synergistic Skin‐Wound Closure

open access: yesAdvanced Science, EarlyView.
A wireless skin‐wound care platform for photothermal‐stem cell‐light (PTSCL) therapy, introduced here, leverages a fully wireless and battery‐free optoelectronic module, gold nanoturf‐mediated photothermal interface, and human adipose‐derived stem cell (hADSC) spheroids to synergistically enhance wound healing.

High Prevalence of Virulence and blaOXA Genes Encoding Carbapenemases Among Acinetobacter baumannii Isolates from Hospitalised Patients in Three Regions of Poland

open access: yesPathogens
Infections caused by Acinetobacter baumannii are increasing worldwide. We evaluated the antibiotic resistance profile, biofilm production, and the frequency of 12 genes encoding carbapenemases and 13 virulence factors in 90 isolates from patients of ...

Strained tetragonal states and Bain paths in metals

open access: yes, 1996
Paths of tetragonal states between two phases of a material, such as bcc and fcc, are called Bain paths. Two simple Bain paths can be defined in terms of special imposed stresses, one of which applies directly to strained epitaxial films.
