Billiard in the space with a time machine
, 2010 We study a system of an elastic ball moving in the non-relativistic spacetime with a nontrivial causal structure produced by a wormhole-based time machine. For such a system it is possible to formulate a simple model of the so-called `grandfather paradox'

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.

Hartree-Fock symmetry breaking around conical intersections
, 2018 We study the behavior of Hartree-Fock (HF) solutions in the vicinity of conical intersections. These are here understood as regions of a molecular potential energy surface characterized by degenerate or nearly-degenerate eigenfunctions with identical ...

Parallel 3D Bioprinting on SLIPS‐Microarrays
Advanced Functional Materials, EarlyView.This work introduces the first truly parallel 3D bioprinting method, enabling both the simultaneous fabrication of hundreds of cell laden hydrogel 3D structures and their HTS in individual liquid compartments. By integrating Digital Light Processing (DLP) stereolithography with functional micropatterns, the platform decouples printing time from array ...

Dispensing Volumetric Additive Manufacturing
Advanced Functional Materials, EarlyView.Dispensing volumetric additive manufacturing (DVAM) prints 3D structures inside a photocurable resin droplet suspended from the tip of a glass pipette, enabling sequential printing without resin vats or manual part removal. Real‐time droplet profiling and ray‐tracing‐based correction compensate for optical distortion at the curved resin‐air interface ...

Numerical Investigation of Laminar Premixed Conical Flame Response to Acoustic Excitation [PDF]
فصلنامه علوم و فناوری فضایی, 2015 Dynamics of laminar premixed conical flame in acoustic-velocity field was studied via numerical simulation. Methane/air combustion was modeled using a single-step, irreversible reaction and diffusion phenomena with a simple but efficient method.
