Log-uniruled affine varieties without cylinder-like open subsets

open access: yes, 2012
A classical result of Miyanishi-Sugie and Keel-McKernan asserts that for smooth affine surfaces, affine-uniruledness is equivalent to affine-ruledness, both properties being in fact equivalent to the negativity of the logarithmic Kodaira dimension.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

open access: yesAdvanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

The effect of laying hen strain on perching biomechanics and keel deviations

open access: yesJournal of Applied Poultry Research
SUMMARY: Keel bone damage (KBD), including deviations and fractures, is a welfare concern in laying hens leading to pain and decreased egg production. Shifting towards alternative housing systems has highlighted a need to evaluate how laying hen strain ...

Unique Aerofoil‐Structured Microfluidics for High Throughput Lipid Nanoparticle Formulation Screening and Scale‐up

open access: yesAdvanced Science, EarlyView.
This study presents aerofoiled microfluidic structures optimized for efficient mixing and lipid nanoparticle (LNP) formation across broad flow rates. Based on this design, two dedicated systems are introduced: MiNANO‐form for high‐throughput formulation screening and MiNANO‐scale for continuous large‐scale production, enabling reproducible, high ...

rWTC‐MBTA Vaccine, Alone and Enhanced with Anti‐PD1, Elicits Immune Responses against CNS and Peripheral B‐Cell Lymphoma

open access: yesAdvanced Science, EarlyView.
An autologous whole‐tumor‐cell vaccine (rWTC‐MBTA) is evaluated in murine CNS lymphoma. Subcutaneous vaccination activates dendritic cells, broadens T‐cell priming, and drives lymphocyte trafficking to brain tumors, producing durable tumor control. Longitudinal bioluminescence and adoptive‐transfer assays verify CNS engagement. Combination with anti‐PD‐

Low YTHDC1 Expression Upregulates FSCN1 to Promote Nuclear F‐Actin Formation and Facilitate Double‐strand DNA Breaks Repair in TMZ‐Resistant Glioblastoma

open access: yesAdvanced Science, EarlyView.
This study revealed that low expression of YTHDC1 in TMZ‐resistant GBM cells leads to increased FSCN1 expression, which is suppressed by m6A modification. FSCN1 activates the CDC42/N‐WASP/Arp2/3 axis in the cell nucleus by recruiting the guanine nucleotide exchange factor (GEF) family member FGD1, thereby promoting F‐actin polymerization in the nucleus.

Autocrine Netrin‐1 Signaling in Hepatic Stellate Cells Drives Liver Fibrosis and Diet‐Induced Metabolic Dysfunction‐Associated Steatohepatitis in Mice

open access: yesAdvanced Science, EarlyView.
Netrin‐1 expression is upregulated in hepatic stellate cells (HSCs) during metabolic dysfunction–associated steatohepatitis and injury‐mediated liver fibrosis. Secreted Netrin‐1 establishes an autocrine positive feedback loop by binding to UNC5B receptors on HSCs.
