Reinforcement learning (RL) is frequently used to increase performance in text generation tasks, including machine translation (MT), notably through the use of Minimum Risk Training (MRT) and Generative Adversarial Networks (GAN). However, little known about what how these methods learn context MT. We prove that one most common RL for MT does not optimize expected reward, as well show other take an infeasibly long time converge. In fact, our...

Generative neural models have improved dramatically recently. With this progress comes the risk that such will be used to attack systems rely on sensor data for authentication and anomaly detection. Many learning are installed worldwide, protecting critical infrastructure or private against malfunction cyber attacks. We formulate scenario of an system facing generative impersonation attacks, characterize it from a theoretical perspective...

A leading hypothesis for the surprising generalization of neural networks is that dynamics gradient descent bias model towards simple solutions, by searching through solution space in an incremental order complexity. We formally define notion learning and derive conditions on depth initialization which this phenomenon arises deep linear models. Our main theoretical contribution a dynamical separation result, proving while shallow models can...

Abstract Most parameterizations of droplet concentration at cloud base in models are derived under the assumption that all droplets form by nucleation dry CCN crossing lifting condensation level updraft. In this study, a novel method calculation supersaturation maximum and is described takes into account existence liquid nucleation. Liquid exists haze particles, as well raindrops. It shown presence water inside non-activated CCN, raindrops...

Abstract The facile one-pot synthesis of poly(ethylene glycol)@silica hybrid microparticles (PEG@silica HMPs) by an oil-in-oil (o/o) emulsification and non-aqueous sol-gel method is reported. HMPs preparation process begins with the PEG formic acid in heptane containing a polymeric surfactant tetraethyl orthosilicate (TEOS). Then, takes place at interface droplets which reacts TEOS to create silica shell. In addition, part intermediates form...

Abstract The association fibers of the superior longitudinal fasciculus (SLF) connect parietal and frontal cortical regions in human brain. SLF comprises three distinct sub-bundles, each presenting a different anatomical trajectory, specific functional roles. Nevertheless, vivo studies often consider entire complex as single entity. In this work, we suggest data-driven approach that relies on microstructure measurements for separating SLF-III...

Abstract Soil water repellency (SWR) has a substantial effect on soil?water hydrology: it hinders infiltration, leading to enhanced surface runoff and soil erosion, causes preferential flow in the profile beyond that from soil's natural heterogeneity. SWR is associated with organic matter content, latter added by vegetation exudates, litter residues, forest fires, replacement of fresh treated wastewater for irrigation. Surfactants are...

Abstract We report the assembly of an asymmetric membrane consisting octadecyltrimethoxysilane (ODTMS) Langmuir film covalently attached to a sol-gel based sublayer, supported by mesoporous membrane. The ODTMS was compressed at interface subphase containing tetramethoxysilane (TMOS), formamide and polyethylenimine. Exposure NH3 vapours increased pH (pHinterface) catalysed condensation TMOS. layers self-healing nature, due ?-pressure set-up...

Abstract This study presents a directly aggregated pseudo-ternary system. The three apexes of the investigated system represent surfactant phase [Tween 80:propylene glycol (9:1 wt ratio)], an oil [isopropyl myristate:benzyl alcohol (7.5:2.5?wt and water. Within system, water dilution line, termed N91 (90?wt% 10?wt% phase), was found to transparent thermodynamically stable compositions from concentrate high (>95?wt% water). Despite that be...

Abstract Effective instruction for conceptual change should aim to reduce the interference of irrelevant knowledge structures, as well improve sense-making counterintuitive scientific notions. Refutation texts are designed support such processes, yet evidence its effect on individual robust, complex misconceptions has not been equivocal. In present work, we examine whether effects refutation text reading in biological evolution can be...

Abstract Remote sensing of night light emissions in the visible band offers a unique opportunity to directly observe human activity from space. This has allowed host applications including mapping urban areas, estimating population and GDP, monitoring disasters conflicts. More recently, remotely sensed lights data have found use understanding environmental impacts (light pollution), their on health. In this review, we outline historical...

Abstract Cannabidiolic acid methyl ester (HU-580) is a more stable compound than cannabidiolic (CBDA) which has been shown to be effective in reducing nausea, anxiety, depression behaviors animal models. Here we extend the investigation of this determine its effect on sleep-wake cycle male Wistar rats. HU-580 dose-dependently (0.1, 1.0 or 100??g/Kg, i.p.) prolonged wakefulness (W) and decreased slow wave sleep (SWS) duration whereas rapid eye...

Abstract Quantum dots offer superior optical features and hold a great potential as an imaging tool in comparison to ?conventional? fluorescent dyes. However, vivo application inflammatory-associated disorders is limited due toxicity following systemic administration. Vascular inflammation contributes cardiovascular diseases such restenosis (re-narrowing of the artery angioplasty), poor prognosis associated with increased number...
