Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

open access: yesExperimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Chosen-Key Distinguishing Attacks on Full AES-192, AES-256, Kiasu-BC, and More

open access: yesIACR Transactions on Symmetric Cryptology
At CRYPTO 2020, Liu et al. demonstrated that many differentials on Gimli are, in fact, incompatible. Similar incompatibilities also arise in relatedkey differentials on AES, which are typically addressed in an ad-hoc manner by incorporating additional ...

Related-Tweakey Impossible Differential Attack on Reduced-Round Deoxys-BC-256 [PDF]

open access: yes, 2018
Deoxys-BC is the internal tweakable block cipher of Deoxys, a third-round authenticated encryption candidate at the CAESAR competition. In this study, by adequately studying the tweakey schedule, we seek a six-round related-tweakey impossible ...

Key Guessing Strategies for Linear Key-Schedule Algorithms in Rectangle Attacks [PDF]

open access: yes, 2022
When generating quartets for the rectangle attacks on ciphers with linear key-schedule, we find the right quartets which may suggest key candidates have to satisfy some nonlinear relations. However, some quartets generated always violate these relations,

Early Radiation Therapy Response Assessment Using Multi‐Scale Photoacoustic Imaging

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
Tomographic and mesoscopic photoacoustics capture intratumoural features of radioresistance and response. ABSTRACT There is a critical unmet clinical need to identify biomarkers that predict and detect radiation therapy (RT) response in cancer. Using the unique capabilities of multi‐scale photoacoustic imaging (PAI) to depict tumor oxygenation and ...

m5C‐Modified tRF3b‐CysGCA‐23 Suppresses Bladder Cancer Malignancy by Repressing H3K18 Lactylation via Stabilizing RBM4

open access: yesAdvanced Science, Volume 13, Issue 26, 8 May 2026.
In this study, we identified an NSUN6‐dependent m5C‐modified tsRNA, m5C‐tRF3b CysGCA‐23 (mtRC), that is downregulated in BC and inversely correlated with disease progression. Mechanistically, mtRC suppresses BC malignancy by stabilizing RBM4, attenuating glycolysis, and thereby limiting H3K18 lactylation–mediated activation of IL1RAP and VASH2 ...

HCTR+: An Optimally Secure TBC-Based Accordion Mode

open access: yesIACR Transactions on Symmetric Cryptology
The design of tweakable wide-block ciphers has advanced significantly over the past two decades. This evolution began with the wide-block cipher by Naor and Reingold.

ZCZ - Achieving n-bit SPRP Security with a Minimal Number of Tweakable-block-cipher Calls [PDF]

open access: yes, 2018
Strong Pseudo-random Permutations (SPRPs) are important for various applications. In general, it is desirable to base an SPRP on a single-keyed primitive for minimizing the implementation costs.

Structural Characterization, β‐Cyclodextrin Polymer Interaction, and Biological Assessment of the N‐Terminal Peptide from the RPD‐1 Big Defensin of Ruditapes p hilippinarum

open access: yesChemistry–Methods, Volume 6, Issue 5, May 2026.
Defensins are a large and ancient family of host–defence peptides present across vertebrates, invertebrates, and plants, where they play a crucial role in innate immunity. Among them, big defensins represent a structurally distinctive subfamily characterized by a hydrophobic N‐terminal domain and a cysteine‐rich C‐terminal β‐defensin‐like domain. Here,
