Reflective Inverse Diffusion [PDF]
Applied Sciences, 2016 Phase front modulation was previously used to refocus light after transmission through scattering media. This process has been adapted here to work in reflection. A liquid crystal spatial light modulator is used to conjugate the phase scattering properties of diffuse reflectors to produce a converging phase front just after reflection.

Molecular Oncology, EarlyView.We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

Diffuse reflectance imaging with astronomical applications [PDF]
, 2011 Diffuse objects generally tell us little about the surrounding lighting, since the radiance they reflect blurs together incident lighting from many directions. In this paper we discuss how occlusion geometry can help invert diffuse reflectance to recover

The Diffusion of Innovations: Some Reflections [PDF]
International Journal of the Economics of Business, 2018 This paper discusses a number of interrelated topics relating to the economics of innovation diffusion that merit further research and study. These topics encompass: how innovations are not just technological, may be horizontal or vertical, and may develop over time; the role in the diffusion process of complementarities across and substitutability ...

Molecular Oncology, EarlyView.The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Illumination invariance and shadow compensation on hyperspectral images [PDF]
, 2014 To obtain intrinsic reflectance of the scene by hyperspectral imaging systems has been a scientific and engineering challenge. Factors such as illumination variations, atmospheric effects and viewing geometries are common artefacts which modulate the way

Accurate and fast event-based shape measurement of mixed reflectance scenes
Nature CommunicationsEvent-based structured light systems have recently emerged as an exciting alternative to frame-based triangulation for 3D measurement of diffuse surfaces, offering high dynamic range and fast capture speed, but at the cost of reduced data quality ...

Reflected Diffusion Processes with Jumps
The Annals of Probability, 1985 In this paper, the authors study the question of building solutions of stochastic differential equations with reflecting boundary conditions, corresponding to reflected diffusion processes with jumps. To do so, they adapt to the case of jump processes the penalty argument used by many authors.
