Sensorized Engineered Tissues with Built‐in Thermoregulation and Nutrient Supply
Advanced Functional Materials, EarlyView.This work introduces a granular hydrogel‐based tissue engineering platform that includes a closed‐loop temperature control to maintain 37°C and sustainably releases nutrients, thereby enabling cells to retain a high viability even if stored at room temperature for up to 24 h.

Achieving sub-diffraction imaging through bound surface states in negative-refracting photonic crystals at the near-infrared [PDF]
, 2008 We report the observation of imaging beyond the diffraction limit due to bound surface states in negative refraction photonic crystals. We achieve an effective negative index figure-of-merit [-Re(n)/Im(n)] of at least 380, ~125x improvement over recent ...

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control
Advanced Functional Materials, EarlyView.A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Usefulness of Terminal Deoxynucleotidyl Transferase as Prognosticator in Leukemia Patients
The International Journal of Biological Markers, 1993 Peripheral blood samples from 55 previously untreated leukemia patients (33 males, 22 females) were analysed for terminal deoxynucleotidyl transferase (TdT) activity.

Gravitino production in a thermal Universe revisited
Physics Letters B, 2017 We study the production of spin 1/2 gravitinos in a thermal Universe. Taking into account supersymmetry breaking due to the finite thermal energy density of the Universe, there is a large enhancement in the cross section of production of these gravitino ...

An investigation of South Pole HOx chemistry: Comparison of model results with ISCAT observations [PDF]
, 2001 Unexpected high levels of OH and NO were recorded at the South Pole (SP) Atmospheric Research Observatory during the 1998-99 ISCAT field study. Model simulations suggest a major photochemical linkage between observed OH and NO.
