Cognition‐inspired behavioural feature identification and motion planning ways for human‐like automated driving vehicles
Authors: Xie Shanshan , Zheng Jingyue , Wang Jianqiang 
Published: November 2022

AbstractHuman‐like automated driving strategies could have advantages in traffic safety and comfort. However, the primary features of human‐like driving behaviors are not clear yet. To deal with this problem, inspired by drivers’ cognition way, a simple method is proposed to identify the critical parameters for human‐like driving behaviors in extensive scenarios. Then with these parameters as terminal constraints, an interpretable motion planning method is developed in which the longitudinal and lateral planning units are coupled by some state information. With the driving data in the published literature, it is validated that the critical parameters match drivers’ behaviors well. With experiments on the simulation and real‐car platforms, it is validated that the motion planning method can generate diverse human‐like behaviors in multiple scenarios.
Data reduction and restoration of spectropolarimetric microlensed hyperspectral imager data
Authors: van Noort M. , Doerr H.-P. 
Published: November 2022

Context. A microlensed hyperspectral imager (MiHI) is an integral field spectrograph based on a double-sided microlens array.Aims. To convert the raw data frames of such an instrument to hyperspectral cubes, and restore them to high-resolution science-ready Stokes data, a new kind of data reduction procedure is required.Methods. An optimized ad hoc transfer map of a MiHI prototype was used to convert the raw data into raw hyperspectral form. The transfer map was modified to match the position of the image on the detector, which was found to drift considerably during the course of an observing day. The determination of this position was used to move the recorded flat-field images to the position of the observation, which was found to be a critical step in the accurate gain correction of the raw data cubes. The converted data were found to be suitable for image restoration but still contained unwanted polarimetric structure that needed to be removed.Results. The extracted and restored data were found to be of a similar spatial resolution as the equivalent data from the context imager, while retaining a spectral resolution of approximately 300 000. The noise properties of the raw data were determined by the photon statistics and were found to be consistent with the estimated transparency of the instrument and the integration time of the image sensor. As for all image-restored data, the noise properties of the restored data were found to be dependent on the instrumental and atmospheric point spread function. An attempt to compare the data to other similar data suggested that the data had a spectral and spatial information content comparable to that of a Hinode spectro-polarimetric scan, but with a higher spatial resolution and a temporal cadence of approximately 10s.
Therapeutische Aspekte beim Antiphospholipidsyndrom
Authors: Specker Christof 
Published: November 2022

ZusammenfassungDas Antiphospholipidsyndrom (APS) wird klinisch durch venöse oder
arterielle Thrombosen sowie Schwangerschaftskomplikationen gekennzeichnet und
serologisch durch den Nachweis von Antiphospholipidantikörpern (aPL)
bzw. eines Lupusantikoagulans (LA). In den letzten Jahren wurde evident, dass
insbesondere bei Vorliegen aller drei serologischen Kriterien,
Antikörper gegen Cardiolipin (aCL), gegen ß2-Glykoprotein-1
(aß2-GP1) und ein positives Lupusantikoagulans, die sog.
Triple-Positivität, das Risiko für (weitere) thromboembolische
und geburtshilfliche Komplikationen deutlich erhöht ist. Therapeutisch
werden Thrombozytenaggregationshemmer (ASS), Heparin und Vitamin K Antagonisten
eingesetzt. Von der Verwendung direkter oraler Antikoagulantien beim APS wird
abgeraten. Eine Immunsuppression ist für die Vermeidung weiterer
thromboembolischer Komplikationen eines APS nicht wirksam.

Zusammenfassung
Gegenstand und Ziel Gliedmaßenfrakturen stellen einen Großteil der orthopädischen Erkrankungen beim Heimtier-Kaninchen dar und sind ein häufiger Vorstellungsgrund in derPraxis. Sowohl die Frakturätiologie als auch die Eigenschaften der Traumata unterscheiden sich im Vergleich zu den Patienten Hund und Katze. Die konservativen und chirurgischen Versorgungsmethoden müssen an diese Besonderheiten angepasst werden. Welche langfristigen Auswirkungen Frakturen und gewählte Therapieoptionen nach Abschluss des Therapiezeitraumes haben, ist für Kaninchen bisher wissenschaftlich nicht detailliert beschrieben.
Material und Methoden Der Artikel befasst sich im Rahmen einer Fallserie mit 13 Frakturpatienten, deren zurückliegendes Traumageschehen retrospektiv beleuchtet wird. Die Kaninchen wurden in Wiedervorstellungen sowohl orthopädisch als auch mit bildgebenden Verfahren erneut untersucht.
Ergebnisse Orthopädische Auffälligkeiten in Form von abduzierten Gliedmaßenhaltungen konnten im Rahmen der Kontrolluntersuchungen bei 4 Patienten festgestellt werden. Arthrotische Knochenzubildungen waren mittels bildgebender Verfahren bei 12 der 13 untersuchten Tiere darstellbar – in 6 Fällen in hochgradigem Ausmaß. In 10 von 13 Fällen konnte eine Verkürzung des frakturierten Knochens ermittelt werden.
Schlussfolgerung und klinische Relevanz Orthopädische Spätfolgen bei Frakturpatienten konnten im Patientengut mehrmalig nachgewiesen werden. Veränderungen der Gliedmaßenhaltung oder des Gangbildes werden nicht immer durch die Patientenbesitzer erkannt. Auch nach Abschluss der initialen Therapie sollten routinemäßige Kontrolluntersuchungen der Kaninchen erfolgen, um mögliche Spätfolgen zeitnah erkennen und gegebenenfalls adäquat behandeln zu können.
Synthesis of N-Acyl Pyrroles and Isoindoles from Oxime Ester Precursors via Transition-Metal-Catalyzed Iminocarboxylation
Authors: Lee Daesung , Su Siyuan 
Published: November 2022

AbstractWe describe Pt(II)- and Fe(III)-catalyzed iminocarboxylations of oxime esters conjugated with 1,3-enyne and an ortho-alkynylarene moiety, followed by a spontaneous O→N acyl migration of the enol carboxylate intermediate to generate N-acyl pyrroles and isoindoles. The reaction scope for pyrrole synthesis is general, whereas the formation of isoindoles has a relatively narrow scope because of their instability.
Overuse of Proximal Fecal Diversion in Colorectal Surgery
Authors: Lyman William Buckley , Whitlow Charles B. 
Published: November 2022

AbstractMany surgeons tend to overuse proximal fecal diversion in the setting of colonic surgery. The decision to proximally divert an anastomosis should be made with careful consideration of the risks and benefits of proximal diversion. Proximal diversion does not decrease the rate of anastomotic leak, but it does decrease the severity of leaks. Anastomotic height for low pelvic anastomoses, hemodynamic instability, steroid use, male sex, obesity, malnutrition, smoking, and alcohol abuse increase the rate of anastomotic leak. Biologics, most immunosuppressive agents, unprepped colons, and radiation for rectal cancer do not contribute to increased rates of anastomotic leak.Proximal fecal diversion creates additional potential morbidity, higher rates of readmission, and need for a subsequent hospitalization and operation for reversal. Additionally, diverted patients have higher rates of anastomotic stricture and delayed recognition of chronic leaks. These downsides to diversion must be weighed with a patient's perceived ability to handle the physiologic stress and consequences of a severe leak if reoperation is required. When trying to determine which patients can handle a leak, the modified frailty index can help to objectively determine a patient's risk for increased rate of morbidity and failure to rescue in the event of a leak.While proximal diversion is still warranted in many cases, we find that certain clinical scenarios often lead to overuse of proximal diversion. The old surgical adage “If you are considering diverting, you should probably do it” should be tempered by an understanding of the risk and benefits of diversion.

Published: November 2022

AbstractIleal pouch-anal anastomosis allows for reestablishing gastrointestinal continuity in patients after proctocolectomy. The technical elements of pouch creation and gaining reach into the pelvis are demanding and require a variety of surgical maneuvers to achieve a tension-free anastomosis. We present a brief review of the literature discussing various approaches aimed at improving ileal pouch reach into the low pelvis. Although these techniques are used with different frequencies, they serve as important adjuncts to the gastrointestinal surgeons' armamentarium.
The asymptotic stability of solitons for the focusing mKdV equation with weak weighted Sobolev initial data
Authors: Liu Anran , Fan Engui 
Published: November 2022

In this paper, we consider the Cauchy problem for the focusing modified Korteweg–de Vries (mKdV) equation in line with the weak weighted Sobolev initial data and without the small-norm assumption. We use the inverse scattering transform, the auto-Bäcklund transformation, and the ∂̄-steepest descent method to obtain the asymptotic stability of the solitons of the mKdV equation.
Multi-stage voltage droop compensation based on resonant circuit for unipolar solid-state Marx Generators
Authors: Rao Junfeng , Huang Yibo , Wang Xiuzhi , Zhuang Longyu , Zhuang Jie , Ji Zhenyu 
Published: November 2022

The low-voltage droop of high-voltage pulses is required to provide stable pulsed electric fields in many applications. Increasing the capacitance of energy storage capacitors increases both the size and the cost of the system. In this paper, four compensation stages based on the resonant circuit have been inserted into a 16-stage solid-state Marx generator to compensate for the voltage droop in different conditions. The nearly linear part of the sinusoidal voltage is precisely added to the load during discharging as compensation, and the rectangular pulsed voltage with little droop can be realized. Different numbers of compensation stages and different resonant inductances can compensate the droop to different levels, which means the compensation effect is also adjustable. Moreover, these compensation stages can operate as common stages in Marx generators as long as we open-circuit the resonant circuits. Since the capacitors in resonant compensation stages are also charged in parallel with capacitors in common stages, no auxiliary power supply is required. Simulating and experimental results show that the droop of a 9 kV pulse can be ideally compensated over a 500 Ω resistive load at various pulse widths. The pulse width should be shorter than the length of the nearly linear part of the sinusoidal voltage.
Injection of low-energy SiCH5+ ion-beam to Si substrate during chemical vapor deposition process using methylsilane

Published: November 2022

Silicon carbide (SiC) films produced on Si substrates by the thermal chemical vapor deposition (CVD) method using methylsilane (MS) were compared with those made by the mass-selected ion-beam deposition (MSIBD) method using MS-derived 100 eV SiCH5+ ions. We also investigated the effect of SiCH5+ ion injections during the CVD process. When the substrate was 550 °C, no distinct peaks were found in the Fourier transform infrared (FTIR) spectroscopy spectra of the samples obtained by both CVD and MSIBD. By contrast, an obvious FTIR peak due to the presence of SiC was observed when SiCH5+ ions were injected to a substrate in conjunction with MS. In the case of 650 °C, we found that the film thickness was significantly increased when additional SiCH5+ ions were injected during the CVD process using MS. These results suggest that the interaction between MS and SiCH5+ has some effects on the SiC film formation at the substrate temperatures 550 and 650 °C. When the substrate temperature was set at 750 °C, the effect of the SiCH5+ ion injection on the SiC film formation was negligibly small compared to that of CVD.

Published: November 2022

Context Chickens are the most important livestock in the Democratic Republic of Congo in particular and in Africa in general; they are kept for their meat and eggs for nutrition and economic status. The availability of chicken diversity information is very important in selection of breeds and in conservation of genetic resources. Aims This study aimed to determine allelic variability, genetic diversity, and genetic relationships of the indigenous chicken populations from the South Kivu region to support breeding programs and genetic resource conservations. Methods The LEI0258 microsatellite marker within the major histocompatibility complex gene region was used for genotyping. The LEI0258 locus amplicon sequences of 163 indigenous chickens were analysed. Key results The number of R13 and R12 repeats varied from 1 to 21 and from 3 to 21 respectively, whereas several combinations of indels and single-nucleotide polymorphisms were observed in the microsatellite flanking regions. In total, 45 different LEI0258 alleles ranging from 193 to 473 bp were determined, including 14 private alleles (Np). Expected heterozygosity (He) varied from 0.864 (Mwenga) to 0.938 (Bukavu), with a mean of 0.911, and observed heterozygosity (Ho) ranged from 0.417 (Uvira) to 0.667 (Mwenga), with a mean of 0.519. The analysis of molecular variance (AMOVA) showed higher genetic variation within individuals (56%) than among individuals (43%) and among chicken populations (1%). Clustering into three admixed gene pools (K = 3) showed the relationships among the chicken populations. Conclusion The present study showed the existence of high genetic diversity in chicken populations from South Kivu. Implications This study provides information useful for better conservation and breeding strategies of indigenous chicken populations in South Kivu.
Bayesian phylogenetics illuminate shallower relationships among Trans-Himalayan languages in the Tibet-Arunachal area

Published: November 2022

AbstractKho-Bwa, Hrusish, Mishmic, Tani, and Tshangla are language clusters that have been recurrently proposed as subgroups of the Trans-Himalayan (also known as Tibeto-Burman and Sino-Tibetan) language family. Nonetheless, their internal classification, as well as the relation with each other and with other linguistic groups in the family, is hitherto unresolved. We use lexical data on these groups and dated phylogenies to investigate such internal classifications. We base our examination on previous research into the language family in the Tibet-Arunachal area, and follow a computer-assisted approach of language comparison to perform Bayesian phylolinguistic analysis. As earlier phylogenetic studies on this family included little data related to this geographic area, we took a subset of the best available dataset and extended it with vocabularies for the Kho-Bwa and Hrusish clusters, also including one Mishmic, two Tani, two Tshangla, and five East Bodish languages to cover the major languages and linguistic subgroups neighboring these clusters. Our results shed light on the internal and external classification of the Kho-Bwa, Hrusish and Bodish languages, and allow us to share valuable experience on the extent to which similar approaches can be applied to the phylogenetic analysis of the Trans-Himalayan language family.
Preinitial denasalisation and palatal fortition in Khroskyabs and the Gyalrongic word for ‘man’
Authors: Lai Yunfan 
Published: November 2022

AbstractThere are four distinct forms conveying the meaning of ‘human, person, man’ across Gyalrongic languages. The default type (Japhugtɯ-rme),the rounded type (Khroskyabsvɟú), the Stau type (Geshizavdzi)and the uvular type (Geletuotaˈʁap). Except for the default type, which has cognates in many other Sino-Tibetan languages, the origins of the other types are to date obscure and understudied. This paper first studies the phenomena of preinitial denasalisation and palatal fortition in the history of Khroskyabs, and then puts forward etymological solutions to the rounded and Stau types based on these sound changes. Both types are historical compounds with the first element related to the default type. The second element of the rounded type is cognate with Tangutlụʶ¹‘man’, and the second element of the Stau type is cognate with Proto-Loloish *tsaŋ¹‘man’ (Bradley 1979).
If you want to cross singularity, wrap it!
Authors: Nakayama Yu 
Published: November 2022

Abstract
In two-dimensional string theory, a probe D0-brane does not see the black hole singularity due to a cancellation between its metric coupling and the dilaton coupling. A similar mechanism may work in the Schwarzschild black hole in large D dimensions by considering a suitable wrapped membrane. From the asymptotic observer, the wrapped membrane looks disappearing into nothing while the continuation of the time-like trajectory beyond the singularity suggests that it would reappear as an instantaneous space-like string stretching from the singularity. A null trajectory can be extended to a null trajectory beyond the singularity. Not only the effective particle but an effective string from the wrapped membrane can exhibit the same feature.
Gauge invariants of linearized gravity with a general background metric
Authors: Garg Deepen , Dodin I Y 
Published: November 2022

Abstract
In linearized gravity with distributed matter, the background metric has no generic symmetries, and decomposition of the metric perturbation into global normal modes is generally impractical. This complicates the identification of the gauge-invariant part of the perturbation, which is a concern, for example, in the theory of dispersive gravitational waves (GWs) whose energy–momentum must be gauge-invariant. Here, we propose how to identify the gauge-invariant part of the metric perturbation and the six independent gauge invariants per se for an arbitrary background metric. For the Minkowski background, the operator that projects the metric perturbation on the invariant subspace is proportional to the well-known dispersion operator of linear GWs in vacuum. For a general background, this operator is expressed in terms of the Green’s operator of the vacuum wave equation. If the background is smooth, it can be found asymptotically using the inverse scale of the background metric as a small parameter.
ORKA: Object reconstruction using a K-approximation graph
Authors: Bossmann Florian , Ma Jianwei 
Published: November 2022

Abstract
Data processing has to deal with many practical difficulties. Data is often corrupted by artifacts or noise and acquiring data can be expensive and difficult. Thus, the given data is often incomplete and inaccurate. To overcome these problems, it is often assumed that the data is sparse or low-dimensional in some domain. When multiple measurements are taken, this sparsity often appears in a structured manner. We propose a new model that assumes the data only contains a few relevant objects, i.e. it is sparse in some object domain. We model an object as a structure that can only change slightly in form and continuously in position over different measurements. This can be modelled by a matrix with highly correlated columns and a column shift operator that we introduce in this work. We present an efficient algorithm to solve the object reconstruction problem based on a K-approximation graph. We prove optimal approximation bounds and perform a numerical evaluation of the method. Examples from applications including Geophysics, video processing, and others will be given.
Hierarchical domain structures associated with oxygen octahedra tilting patterns in lead-free (Bi1/2Na1/2)TiO3

Abstract
Hierarchical domain structures associated with oxygen octahedra tilting patterns were observed in lead-free (Bi1/2Na1/2)TiO3 ceramics using aberration-corrected high-resolution transmission electron microscopy (HRTEM). Three types of domains are induced by distinct mechanisms: the ‘orientation-domain’ is induced at micrometer scale formed by different tilting orientations of the oxygen octahedra, the ‘meso-chemical-domain’ occurs at a few tens of nanometer scale by chemical composition variation on the A-site in the ABO3 perovskite structure, and the ‘nano-cluster-region’ runs across several unit-cells with apparent A-site cation segregation with oxygen vacancies clustering around Na cations. Based on HRTEM amplitude contrast imaging (ACI), the correlation between the oxygen octahedral tilting pattern and compositional non-stoichiometry was established. The role of the hierarchical domain structure associated with the tilting patterns of the oxygen octahedra on the ferroelectric behavior of (Bi1/2Na1/2)TiO3 is also discussed.

Abstract

Objective. We propose a method to model families of distributions of particles exiting a phantom with a conditional generative adversarial network (condGAN) during Monte Carlo simulation of single photon emission computed tomography imaging devices. Approach. The proposed condGAN is trained on a low statistics dataset containing the energy, the time, the position and the direction of exiting particles. In addition, it also contains a vector of conditions composed of four dimensions: the initial energy and the position of emitted particles within the phantom (a total of 12 dimensions). The information related to the gammas absorbed within the phantom is also added in the dataset. At the end of the training process, one component of the condGAN, the generator (G), is obtained. Main results. Particles with specific energies and positions of emission within the phantom can then be generated with G to replace the tracking of particle within the phantom, allowing reduced computation time compared to conventional Monte Carlo simulation. Significance. The condGAN generator is trained only once for a given phantom but can generate particles from various activity source distributions.
