Algebraic solutions of tropical optimization problems

open access: yes, 2014
We consider multidimensional optimization problems, which are formulated and solved in terms of tropical mathematics. The problems are to minimize (maximize) a linear or nonlinear function defined on vectors of a finite-dimensional semimodule over an ...

Engineered In Vitro Multi‐Cell Type Ventricle Model Generates Long‐Term Pulsatile Flow and Modulates Cardiac Output in Response to Cardioactive Drugs

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents an innovative in vitro model of a human left ventricle using biofunctionalized PDMS membranes and human iPSC‐derived cardiomyocytes. The engineered ventricle demonstrates stable, long‐term pulsatile flow, and physiological responses to cardioactive drugs.

Actuated Hydrogel Platforms To Study Brain Cell Behavior

open access: yesAdvanced Healthcare Materials, EarlyView.
The complex and dynamic viscoelastic properties of the brain underpin neural plasticity and overall function. Actuating hydrogel platforms support mechanistic research to elucidate how brain cells respond to dynamic microenvironments. This study reviews the mechanobiology of the brain and its impact on brain function in health and disease and describes

Nano‐Topography Enhanced Topological‐Cell‐Analysis in Radiation‐Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Radiotherapy, a treatment that implies exposition of cells to radiation, offers promise to treat cancer. Here, it is hypothesized that the nanoscale details of a scaffold can amplify the response of cells to radiation, measured through topological variables, providing ways to assess the efficacy of Radiotherapy treatment.

Optoelectronic Devices for In‐Sensor Computing

open access: yesAdvanced Materials, EarlyView.
The raw data obtained directly from sensors in the noisy analogue domain is often unstructured, which lacks a predefined format or organization and does not conform to a specific data model. Optoelectronic devices for in‐sensor visual processing can integrate perception, memory, and processing functions in the same physical units, which can compress ...
