A Quantum Mechanical Model of Spherical Supermembranes [PDF]

, 2002
We present a quantum mechanical model of spherical supermembranes. Using superfields to represent the cartesian coordinates of the membrane, we are able to exactly determine its supersymmetric vacua.

Cation‐Driven Valence Change Mechanism in 2D AgCrS2 for Ultralow‐Power and Reliable Memristors

Advanced Science, EarlyView.
A 2D AgCrS2 volatile memristor is shown to switch via a cation‐driven valence change mechanism, where Ag+ reversibly intercalates into tetrahedral vacancies between CrS2 layers to form a conductive Ag2CrS2 pathway without elemental Ag metallization. The device exhibits 0.2 V switching, nA‐compliance power down to 200 pW, and endurance beyond 3 × 105 ...

Validation of the Safe Application of Tokyo Guideline 2018 (TG18) Severity Grading and Treatment Algorithm in Super‐Elderly Patients Aged 85 and Over With Acute Cholecystitis: A Study in the Japanese Tertiary Care Hospital

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background With population aging and extended healthy life expectancy, the management of acute cholecystitis (AC) in patients aged ≥ 85 years has evolved. However, the Tokyo Guidelines 2018 (TG18) for AC provide no specific risk assessment criteria for this population.

Next-Generation Dental Materials: Exploring Bacterial Biofilm Formation on 3D-Printable Resin-Based Composites

Journal of Functional Biomaterials
This study evaluated the microbial growth profile of subgingival multispecies biofilm on 3D-printable resin-based composites (PRBCs). A 96-well cell plate cultivated a 39-species biofilm associated with periodontitis over 7 days.

Thermometric Based‐Microswimmers with Chemical and Optical Engines

Advanced Intelligent Systems, EarlyView.
Temperature sensing at small scales is typically performed using passive luminescent particles. Here, an alternative approach is demonstrated by integrating upconversion thermometry into self‐propelled microswimmers powered by chemical fuels or light. This strategy offers a step toward dynamic thermal sensing at the microscale, relevant to both lab‐on ...
