Recent work has demonstrated the ability of deep reinforcement learning (RL) algorithms to learn complex robotic behaviours in simulation, including domain multi-fingered manipulation. However, such models can be challenging transfer real world due gap between simulation and reality. In this paper, we present our techniques train a) a policy that perform robust dexterous manipulation on an anthropomorphic robot hand b) pose estimator suitable for providing reliable real-time information...

Previous game-theoretic studies of vaccination behavior typically have often assumed that populations are homogeneously mixed and individuals fully rational. In reality, there is heterogeneity in the number contacts per individual, tend to imitate others who appear adopted successful strategies. Here, we use network-based mathematical models study effects both imitation contact on coverage disease dynamics. We integrate network epidemiological with a framework for decision-making, within...

Abstract Friction as a fundamental physical phenomenon dominates nature and human civilization, among which the achievement of molecular rolling lubrication is desired to bring another breakthrough, like macroscale design wheel. Herein, an edge self-curling nanodeformation graphite nanosheets (GNSs) at cryogenic temperature found, then used promote formation nanorollers in friction process towards lubrication. The observation parallel interface give experimental evidence for occurrence...

Tankyrase (TNKS) is a poly-ADP-ribosylating protein (PARP) whose activity suppresses cellular axin levels and elevates β-catenin concentrations, resulting in increased oncogene expression. The inhibition of tankyrase (TNKS1 2) may reduce the β-catenin-mediated transcription inhibit tumorigenesis. Compound 1 previously described moderately potent inhibitor that suffers from poor pharmacokinetic properties. Herein, we describe utilization structure-based design molecular modeling toward novel,...

The general consensus from epidemiological game-theory studies is that vaccination coverage driven by self-interest (Nash vaccination) generally lower than group-optimal (utilitarian vaccination). However, diseases become more severe with age, such as chickenpox, pose an exception to this consensus. An individual choice be vaccinated against chickenpox has the potential harm those not increasing average age at infection and thus severity of well already probability breakthrough infection. To...

Tankyrases (TNKS1 and TNKS2) are proteins in the poly ADP-ribose polymerase (PARP) family. They have been shown to directly bind axin proteins, which negatively regulate Wnt pathway by promoting β-catenin degradation. Inhibition of tankyrases may offer a novel approach treatment APC-mutant colorectal cancer. Hit compound 8 was identified as an inhibitor through combination substructure searching Amgen collection based on minimal binding pharmacophore hypothesis high-throughput screening....

RATIONALE Although Desorption Electrospray Ionization (DESI) Mass Spectrometry Imaging (MSI) is uniquely suited for whole-body (WB) tissue distribution study of drugs, success in this area has been difficult. Here, we present WB studies using DESI-MSI and a new histological tissue-friendly solvent system. METHODS Neonate pups were dosed subcutaneously (SC) with clozapine, compound 1, 2, or 3. Following euthanization by hypothermia, neonates underwent transcardiac perfusion (saline) to remove...

Vaccination has proven effective in controlling many infectious diseases. However, differential effectiveness with regard to pathogen genotype is a frequent reason for failures vaccine development. Often, insufficient immune response induced prevent infection by the diversity of existing serotypes present pathogenic populations bacteria. These vaccines that target too narrow spectrum do not offer sufficient prevention infections, and can also lead undesirable strain replacements. Here, we...

Chromium poisoning has become one of the most common heavy metal occupational diseases with high morbidity and mortality. However, antidotes detoxify whole body are highly toxic. To achieve hepato-targeted chromium detoxification, a novel strategy was developed using aging erythrocyte membranes (AEMs) as biomimetic material coated dimercaptosuccinic acid (DMSA) nanostructured lipid carrier to construct nano-drug delivery system. The particle size, potential, drug loading, encapsulation rate,...

For transient mixed Elastohydrodynamic lubrication (EHL) problems, a novel solution is required to predict friction loss and wear in sliding or rolling parts. However, existing solutions have numerous limitations. In general, the lower oil film thickness is, more serious non-linear problem is. This paper presents an efficient tackle non-linearity of EHL problem. The elastic deformation fluid–solid iteration coupling divided into two parts: One induced by hydrodynamic pressure. part obtained...
