Spatiotemporal control of protein structure and activity in biological systems has important and broad implications in biomedical sciences as evidenced by recent advances in optogenetic approaches. Here, this study demonstrates that nanosecond pulsed laser heating of gold nanoparticles (GNP) leads to an ultrahigh and ultrashort temperature increase, coined as "molecular hyperthermia", which cau...

We discuss the problem of model selection in Genetic Programming using the framework provided by Statistical Learning Theory, i.e. Vapnik-Chervonenkis theory (VC). We present empirical comparisons between classical statistical methods (AIC, BIC) for model selection and the Structural Risk Minimization method (based on VC-theory) for symbolic regression problems. Empirical comparisons of differe...

This paper aims to analyse logistics service providers’ (LSP) willingness employ virtual communities (VC) through emotional connection. The factors influencing the of using VC e-business with a theory technology acceptance model (TAM) are first investigated. Structural equation modelling (SEM) and moderation analysis adopted examine interrelationship intention VCs when considering impact result...

We present a connection between two seemingly disparate fields: VC-theory and graph theory. This connection yields natural correspondences between fundamental concepts in VC-theory, such as shattering and VC-dimension, and well-studied concepts of graph theory related to connectivity, combinatorial optimization, forbidden subgraphs, and others. In one direction, we use this connection to derive...

The influence of the morphology of industrial graphite nanoplate (GNP) materials on their dispersion in polycarbonate (PC) is studied. Three GNP morphology types were identified, namely lamellar, fragmented or compact structure. The dispersion evolution of all GNP types in PC is similar with varying melt temperature, screw speed, or mixing time during melt mixing. Increased shear stress reduces...

The venture capital industry is characterized by strong inter-organizational networks that have been shown to affect VC firm performance and the competitive supply of capital for entrepreneurs. We examine how VC firms’ observable resources are related to tie formation, and thus how networks facilitate the distribution and combination of resources across organizations. Unlike the social networks...

We investigate the relationship between venture capital (VC) networks and investment performance in China. Distinct features of China’s VC networks are captured in our econometric model through the inclusion of an index of network stability and a dummy variable that indicates a VC firm’s connections with the Chinese state. Our econometric analysis shows that a VC firm’s position in its network,...

The generalization ability of discrete time partially recurrent networks is examined. It is well known that the VC dimension of recurrent networks is infinite in most interesting cases and hence the standard VC analysis cannot be applied directly. We find guarantees for specific situations where the transition function forms a contraction or the probability of long inputs is restricted. For the...

background: gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers. objective: the aim of this study is to understand characteristics of secondary electrons generated from interaction of gold nanoparticles gnps with x-rays as a function of nanoparticle size and beam energy and ...
