Systematic Review and Meta‐Analysis on the Efficacy and Safety of Salvage Esophagectomy for T4 Esophageal Squamous Cell Carcinoma

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This meta‐analysis of 208 cases shows that salvage esophagectomy for cT4 esophageal squamous cell carcinoma achieves a 72% R0 resection rate, offering a curative pathway for selected patients. However, it remains a high‐risk procedure with an 18% anastomotic leak rate and 30% major complications (Clavien–Dindo ≥ III).

A Computational Approach for Biomimetic Design of Liver‐On‐A‐Chip

open access: yesAdvanced Intelligent Discovery, EarlyView.
A biomimetic liver‐on‐a‐chip with antiparallel perfusion was designed using COMSOL‐guided simulation to replicate hepatic acinus transport. Full‐scale modelling revealed diffusion‐dominated, length‐dependent nutrient gradients and low‐shear conditions.

Tunable Synthesis of Multi‐Responsive NH‐Containing Helical Nanographenes With a Chiroptical Switching Function

open access: yesAngewandte Chemie, EarlyView.
The Scholl reaction of 1,3,6,8‐tetrakis(oligophenyl)‐appended carbazoles afforded stable NH‐containing helical nanographenes, which showed significant redshift and reversible on/off switching of CPL upon the addition of base and acid, respectively. Furthermore, excited‐state proton transfer occurred in dimethyl sulfoxide to generate anionic species ...

Asymmetric Whisker‐Inspired Sensor Pairs for Enhanced Airflow Sensing on Drones

open access: yesAdvanced Intelligent Systems, EarlyView.
This work incorporates asymmetric cross‐sections into a whisker‐inspired sensor pair to enhance airflow sensing. By comparing signals between two offset asymmetric whiskers, the system improves flow heading estimation and identifies the presence of fan‐generated wind during quadrotor flight.

Selective Sequential Depolymerization of Mixed Plastics Mediated by Photothermal Conversion

open access: yesAngewandte Chemie, EarlyView.
This work provides a selective sequential depolymerization strategy for mixed plastic waste. The method enables depolymerization of poly(L‐lactide), polystyrene, and poly(ethylene terephthalate), including their post‐consumer plastics. Without presorting, monomer separation is achieved by leveraging the distinct chemical reactivities of each polymer in

Linking community structure and climate vulnerability in desert plant assemblages of southern California

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Enantioselective Synthesis of Axially Chiral Diaryl Ethers via Rhodium‐Catalyzed [2 + 2 + 2] Cycloaddition

open access: yesAngewandte Chemie, EarlyView.
An enantioselective rhodium‐catalyzed [2 + 2 + 2] cycloaddition enables the synthesis of axially chiral diaryl ethers. Carbonyl coordination ensures high reactivity and regioselectivity, affording products bearing up to four stereogenic axes with good enantio‐ and diastereoselectivity.

Extroparvum occidentale gen. et sp. nov. and the Cretaceous diversification of Lauraceae

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise The fossil record of Lauraceae extends back to the Early Cretaceous and comprises numerous flowers. However, phylogenetic relationships of many of these fossil flowers remain unresolved. To better understand the early evolutionary history of Lauraceae, we conducted phylogenetic analyses of living and extinct members of the family and ...

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission

open access: yesAngewandte Chemie, EarlyView.
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

Using photovoice to understand community perceptions of firearm risks and protective factors among Asian Americans

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract This study used photovoice methodology to explore Asian Americans' perspectives on the root causes and protective factors of firearm violence in their communities. Photovoice provided a participatory platform for community members to document lived experiences and identify priorities for change.
