CLRe: A Synergistic Dual‐Engine Framework for One‐Step Retrosynthesis Prediction

open access: yesAdvanced Science, EarlyView.
CLRe uses a contrastive difficulty score to order pretrained seq2seq fine‐tuning for retrosynthesis. Reaction embeddings define the ranking score, and a cumulative easy‐to‐hard schedule expands from the easiest subset to the full training set while earlier examples remain active.

JURAJ KRIŽANIĆ - THE GRAMMARIAN OF »OZALJSKI KRUG« (OZALJ CIRCLE)

open access: yesFluminensia: Journal for Philological Research, 1991
»Gramatičko iskazanje ob ruskom jeziku«, written by Juraj Križanić at Tobolsk in 1665, was conceived as an ali-Slavic grammar, in which six Slavic language systems were included but Russian and Croatian were the most represented ones.

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals

open access: yesAdvanced Science, EarlyView.
A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Mepce Restrains Ferroptosis in Prostate Cancer Through 7SK–P‐TEFb Pause Control

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPR screening identifies MEPCE as a pause‐control regulator that restrains ferroptosis in prostate cancer. MEPCE loss releases P‐TEFb/CDK9 from 7SK snRNP control, enhances RNAPII Ser2 phosphorylation, and accelerates NRF2‐HMOX1‐driven labile iron accumulation and lipid peroxidation, revealing a transcriptional kinetic gate that lowers ...

Emergent grammar from a minimal cognitive architecture

open access: yes
In this paper, we introduce a minimal cognitive architecture designed to explore the mechanism sunderlying human language learning abilities. Our model inspired by research in artificial intelligence incorporates sequence memory, chunking and ...

A pH‐Switchable Cerium Single‐Atom Enzyme for Peri‐Implantitis Therapy via JAK‐STAT Signaling Axis‐Mediated Macrophage Reprogramming

open access: yesAdvanced Science, EarlyView.
A pH‐switchable cerium single‐atom enzyme is developed for stage‐specific peri‐implantitis therapy. Acidic conditions trigger antibacterial peroxidase‐like activity, whereas neutral conditions activate an antioxidant superoxide dismutase ‐ and catalase ‐like enzymatic relay. This microenvironment‐adaptive catalytic strategy suppresses the IL‐6/JAK‐STAT

Repurposing a Small Molecule Plant Hormone as a Tunable ON‐Switch for CAR‐T Cell Immunotherapy

open access: yesAdvanced Science, EarlyView.
By engineering a receptor system integrating the plant auxin receptor AFB1 with its co‐receptor IAA7, we enable ligand‐dependent interactions triggered by the plant hormone auxins. This design allows rapid, reversible, and dose‐dependent T cell activation, resulting in potent cytotoxicity against B‐cell lymphoma in vitro and in vivo.
