Agent‐Based Simulations of Lung Tumor Evolution Suggest That Ongoing Cell Competition Drives Realistic Clonal Expansions

open access: yesAdvanced Science, EarlyView.
Computational simulations of tumor evolution are increasingly used to infer the rules underlying cancer growth, with the goal of one day recommending tailored treatments. Here we show that the properties of lung cancer sequencing data are best replicated by a model which assumes that cells compete both to proliferate and survive. ABSTRACT Computational

N–O Dual Functional Group Transposition via Energy Transfer Photocatalysis

open access: yesAdvanced Science, EarlyView.
N–O dual functional group transposition (dFGT) enabled by the photocatalytic energy transfer (EnT) has been developed. This methodology is applicable to both activated and unactivated alkyl derivatives for dFGT, and it also successfully extended to N–N dFGT, demonstrating its general applicability.

Multifunctional Manganese Oxide Nanocomposite Hydrogel With Synergistic Reactive Oxygen Species‐Scavenging, Oxygen‐Generating, Immunomodulatory, and Photothermal Antimicrobial Activities for Enhanced Diabetic Wound Healing

open access: yesAdvanced Science, EarlyView.
CFP/PC@MnO2 hydrogel integrates ROS scavenging, oxygen delivery, oxidative stress reduction, immunomodulation, and photothermal antibacterial properties. The incorporation of PC@MnO2 NPs endows the hydrogel with multiple functional advantages tailored to the pathological microenvironment of diabetic wounds, including efficient ROS clearance, mitigation

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.

Development of Pacing, Electrophysiology and Defibrillation in India

open access: yes, 2002
History of cardiac pacing in India dates back to late 1960s. Kar1 reported that cardiac pacing was introduced in India in 1966. Basu2 while discussing on cardiac pacemaking in Calcutta, mentions that the first pacing was performed in April 1967 at the ...

Data‐Driven Discovery of Unconventional Antiferromagnets

open access: yesAdvanced Science, EarlyView.
A high‐throughput workflow that combines the physics‐informed pre‐screening, high‐throughput exchange calculations, Luttinger‐Tisza analysis and symmetry classification is established for accurate identification of unconventional antiferromagnets from the broad structural database.

Unlocking the Alkynyl Bromide Radical Anion With Alternating Current for Inverse Sonogashira C─H Coupling

open access: yesAdvanced Science, EarlyView.
An alternating current (AC)‐promoted, Pd‐catalyzed ortho‐aryl C─H alkynylation of 2,3‐diaryl acrylaldehydes is described. This synthetic scheme accommodates a broad substrate scope, delivering alkynylated stilbene derivatives with excellent arene site selectivity.

Engineering Slow‐Carrier Interfacial Recombination Enables Tailored Spectral Response

open access: yesAdvanced Science, EarlyView.
This work demonstrates that weak‐drift slow carriers are preferentially captured at generic semiconductor surfaces/interfaces and recombine. This process is manipulated to achieve tailored spectral response. A tens of µm‐wide depletion region is created to observe surface collection rates for photocarriers generated at different positions.

Bond‐Competition‐Driven Enhancement of Surface Basicity and Interfacial Interaction to Boost Photocatalytic Syngas Production

open access: yesAdvanced Science, EarlyView.
A synergetic surface bond competition−hybridization approach was developed to synthesize high‐performance CO2 adsorbents and syngas production photocatalysts via the sulfurization‐driven control of surface basicity and interfacial coupling. The ZnIn2S4−sulfur‐doped MgO/MgAl2O4 nanocomposites showed outstanding photocatalytic efficiency for production ...
