Advanced Healthcare Materials, EarlyView.Minimal residual disease (MRD) leads to cancer relapse and poor survival in ovarian cancer. The lack of representative 3D models limits therapy development. The microfluidics‐based high throughput 3D microtumor platform described here generates clinically‐relevant MRD models. The 3D microtumors recapitulate the molecular signatures of MRD from patients.

A Novel Automatic Approach for Calculation of the Specific Binding Ratio in [I-123]FP-CIT SPECT
Diagnostics, 2020 A fully automatic method for specific binding ratio (SBR) calculation in [123I]ioflupane single-photon emission computed tomography (SPECT) studies was proposed by creating volumes of interest of the striatum (VOIst) and reference region (VOIref) without

Front formation in a ballistic annihilation model [PDF]
Physica A 229, 515 (1996), 1996 We study a simple one-dimensional model of ballisticaly-controlled annihilation in which the two annihilating species are initially spatially separated. The time dependent properties of the annihilation front are exactly derived. It is shown that the front wanders in a brownian fashion around its average value.

Microlenses immersed in nematic liquid crystal with electrically controllable focal length [PDF]
, 1995 A microlens immersed in a nematic liquid crystal cell has been constructed with avariable focal length which can be controlled by applying an analogue voltage to thenematic liquid crystal. The focal length is -910 ± 30 ?

Advanced Healthcare Materials, EarlyView.The use of organ‐on‐a‐chip (OOC) microfluidic platforms is expanding in biomedical research. While this emerging technology is becoming increasingly accessible, the stability of long‐term functional cultures remains a critical challenge to address. This study presents a straightforward, one‐step method for the functionalization of polydimethylsiloxane ...

Dielectric susceptibility of the Coulomb-glass [PDF]
Phys. Rev. B Vol. 59, 910 (1999), 1999 We derive a microscopic expression for the dielectric susceptibility $\chi$ of a Coulomb glass, which corresponds to the definition used in classical electrodynamics, the derivative of the polarization with respect to the electric field. The fluctuation-dissipation theorem tells us that $\chi$ is a function of the thermal fluctuations of the dipole ...

Supramolecular Conductive Hydrogels With Homogeneous Ionic and Electronic Transport
Advanced Materials, EarlyView.Poly(3,4‐ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) based conductive hydrogels have received great attention in bioelectronics on account of their tissue‐like mechanical properties. However, inhomogeneous morphologies of the conducting PEDOT phase limits their electrical and mechanical properties. Here, supramolecular hydrogels with self‐

Case Reports in Medicine, 2011 We describe the multimodality treatment regimen of a 53-year-old man diagnosed with olfactory neuroblastoma (Kadish stage C) in the right nasal cavity extending into the ethmoid sinus and across the cribriform plate.

On the Stability of a class of Modified Gravitational Models [PDF]
Int.J.Theor.Phys.47:898-910,2008, 2007 Motivated by the dark energy issue, a minisuperspace approach to the stability for modified gravitational models in a four dimensional cosmological setting are investigated. Specifically, after revisiting the $f(R)$ case, $R$ being the Ricci curvature, we present a stability condition around a de Sitter solution valid for modified gravitational models ...
