Anomaly detection for time-series data has been an important research field a long time. Seminal work on anomaly methods focussing statistical approaches. In recent years increasing number of machine learning algorithms have developed to detect anomalies time-series. Subsequently, researchers tried improve these techniques using (deep) neural networks. the light methods, body lacks broad comparative evaluation statistical, and deep methods. This paper studies 20 univariate from all three...
This report presents the synthesis and use of novel derivatives 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO, 1 ) 5,5‐dimethyl‐1,3,2‐dioxaphosphorinan‐2‐one (DDPO, 2 as flame retardant additives for epoxy resins. DOPO‐based DDPO‐based compounds were synthesized via nucleophilic substitution with 1,3,5‐tris‐(2‐hydroxyethyl) isocyanurate (THIC, 3 subsequent oxidation (Schemes 2). Another trivalent DOPO derivative recently reported by our group was obtained transamination followed a...

Abstract Direct numerical simulations (DNS) of turbulent thermal convection in a box-shaped domain with regular surface roughness at the heated bottom and cooled top surfaces are conducted for Prandtl number $\mathit{Pr}=0.786$ Rayleigh numbers $\mathit{Ra}$ between $10^{6}$ $10^{8}$ . The is introduced by four parallelepiped equidistantly distributed obstacles attached to plate, located symmetrically plate. By varying height width obstacles, we investigate influence wall on heat transport,...
Abstract We analyse the wind and boundary layer properties of turbulent Rayleigh–Bénard convection in a cylindrical container with aspect ratio one for Prandtl number $\mathit{Pr}= 0. 786$ Rayleigh numbers ( $\mathit{Ra}$ ) up to $1{0}^{9} $ by means highly resolved direct numerical simulations. identify time periods which orientation large-scale circulation (LSC) is nearly constant order perform statistical analysis LSC. The then reduced two dimensions considering only plane Within this LSC...
Heat transport enhancement and flow topology of turbulent Rayleigh-B\'enard convection under geometrical confinement are studied numerically for over two decades Prandtl numbers, with Ra fixed at ${10}^{8}$.
Bell's theorem has been proposed to certify, in a device-independent and robust way, blocks either producing or measuring quantum states. In this Letter, we provide method based on certify coherent operations for the storage, processing, transfer of information. This completes set tools needed all building computer. Our distinguishes itself by its robustness experimental imperfections, so could be used that today's devices are qualified usage future computers.
Climate models are fundamental in shaping the narratives of future impacts humans on climate, yet their capacity to illuminate past climate remains largely unexplored. This study explores possibilities, challenges and limitations using comprehensive Earth System  Models reconstruct climatic niches hominins during Last Interglacial (LIG) Glacial Maximum (LGM).Hominin primarily shaped by temperature precipitation patterns, incorporating archaeological environmental constraints.

Abstract This article discusses the behavior of seven organophosphorus compounds under Atherton–Todd conditions. Therefore, reactivity and selectivity different (phen)oxaphosphinines, dioxaphosphinines, dioxaphosphinanes, diphenylphosphine oxide with three nucleophiles were systematically studied. The results prove versatility reaction to a broad range phosphorus environments reactive PH bonds. studied in this chosen as model substrates for amines alcohols. Because molecules are important...
Background Neglect can be a long-term consequence of chronic stroke that impede an individual's ability to perform daily activities, but and discrete forms difficult detect. We developed evaluated the "immersive virtual road-crossing task" (iVRoad) identify quantify neglect symptoms in patients.
We derive the asymptotes for ratio of thermal to viscous boundary layer thicknesses infinite and infinitesimal Prandtl numbers $\text{Pr}$ as functions angle $\ensuremath{\beta}$ between large-scale circulation an isothermal heated or cooled surface case turbulent convection with laminar-like layers. For this purpose, we apply Falkner-Skan ansatz, which is a generalization Prandtl-Blasius one nonhorizontal free-stream flow above layer. Based on our direct numerical simulations (DNS)...
Maneuvering heavy load transports on narrow roads is a challenging task that requires precise and reliable planning in advance. This paper introduces novel procedure improves execution of by using path algorithms. The proposed algorithm augments existing approaches significantly to enable for multi-body vehicles with multi-axle steering.
Repetitive transorbital alternating current stimulation (rtACS) improves vision in patients with chronic visual impairments and an acute treatment increased survival of retinal neurons after optic nerve crush (ONC) rodent models system injury. However, despite this protection no functional recovery could be detected rats, which was interpreted as evidence "silent survivor" cells. We now analysed the mechanisms underlying survival" effect. Using vivo microscopy retina we investigated...
The steady improvement of advanced driving assistance systems (ADAS) and the leap towards automated (AD) require novel methods for assessing safety those, which is a major subject current research. Different proposals cope with massive testing effort to assure such systems. These include virtualization testing, usage stochastic reduction necessary real world tests. Despite these different approaches, they all rely on same basis: behavior assessment vehicle under test, results in measurement...
Assessment and testing are among the biggest challenges for release of automated driving. Up to this date, exact procedure achieve homologation is not settled. Current research focuses on scenario-based approaches that represent driving scenarios as test cases within a scenario space. This avoids redundancies in testing, enables inclusion virtual into process, makes statement about coverage possible. However, it unclear how define such space criterion. work presents novel approach definition...
A recent experiment reported the first violation of a Bell correlation witness in many-body system [Science 352, 441 (2016)]. Following discussions this Letter, we address here question statistics required to correlated states, i.e., states violating inequality, such experiments. We start by deriving multipartite inequalities involving an arbitrary number measurement settings, two outcomes per party and one- two-body correlators only. Based on these inequalities, then build up improved...

Abstract Different approaches were applied to obtain new diol compounds based on dibenzo[c.e][1,2]oxaphosphorine 2‐oxide (DOPO, 1 ) and diethanolamine (DEolA). Of four processes investigated, a four‐step synthesis of containing propionic acid amide DEolA proved be the most efficient one. In addition, intramolecular amine salt DOPO derivative with ring‐opened structure was obtained by reinvestigation reaction paraformaldehyde. The Atherton–Todd investigated as well. © 2011 Wiley Periodicals,...
