description: BANYAN $Σ$ is a new Bayesian algorithm to identify members of young stellar associations within 150 pc of the Sun. It includes 27 young associations with ages in the range ~1-800 Myr, modelled with multivariate Gaussians in 6-dimensional XYZUVW space. It is the first such multi-association classification tool to include the nearest sub-groups of the Sco-Cen OB star-forming region, the IC 2602, IC 2391, Pleiades and Platais 8 clusters, and the $ρ$ Ophiuchi, Corona Australis, and Taurus star-formation regions. A model of field stars is built from a mixture of multivariate Gaussians based on the Besançon Galactic model. The algorithm can derive membership probabilities for objects with only sky coordinates and proper motion, but can also include parallax and radial velocity measurements, as well as spectrophotometric distance constraints from sequences in color-magnitude or spectral type-magnitude diagrams. BANYAN $Σ$ benefits from an analytical solution to the Bayesian marginalization integrals that makes it more accurate and significantly faster than its predecessor BANYAN II. A contamination versus hit rate analysis is presented and demonstrates that BANYAN $Σ$ achieves a better classification performance than other moving group classification tools, especially in terms of cross-contamination between young associations. An updated list of bona fide members in the 27 young associations, augmented by the Gaia-DR1 release, are presented. This new tool will make it possible to analyze large data sets such as the upcoming Gaia-DR2 to identify new young stars. IDL and Python versions of BANYAN $Σ$ are made available with this publication. (shortened)

description: A system of neutral atoms trapped in an optical lattice and dispersively coupled to the field of an optical cavity can realize a variation of the Bose-Hubbard model with infinite-range interactions. This model exhibits a first order quantum phase transition between a Mott insulator and a charge density wave, with spontaneous symmetry breaking between even and odd sites, as was recently observed experimentally [Landig \emph{et. al.}, Nature {\bf 532} (2016)]. In the present paper we approach the analysis of this transition using a variational model which allows us to establish the notion of an energy barrier separating the two phases. Using a discrete WKB method we then show that the local tunneling of atoms between adjacent sites lowers this energy barrier and hence facilitates the transition. Within our simplified description, we are thus able to increment the phase diagram of the model with information concerning the height of the barrier separating the metastable minima from the global minimum in each phase, which is an essential aspect for the understanding of the reconfiguration dynamics induced by a quench across a quantum critical point.

description: In this work we have developed a prototype gaseous pixel detector by combining a micromegas grid with a Timepix3 chip for the readout. The micromegas foil supported by a matrix of pillars about 50 $\mathrm{μm}$ high was manually placed on top the chip. By placing a cathode foil above the chip an ionization detector was created with a drift gap of 13.5 mm. The Timepix3 chip, thanks to the simultaneous measurement of the time-of-arrival (ToA) and charge via time-over-threshold (ToT) allows corrections to remaining timewalk effects, improving further the position resolution along the drift direction. We present the timewalk correction for Timepix3 chip obtained with real data from a particle beam and its impact on the tracking performance. The results obtained show an significant improvement on the position resolution for single-hits and tracks along the drift direction compared to previous experiments.

Lademanagementmethode für Elektrofahrzeuge zur Senkung von Installations- und Betriebskosten von Ladepunkt-Gruppen

description: Der notwendige Ausbau der Ladeinfrastruktur aufgrund der zunehmenden Verbreitung von Elektrofahrzeugen stellt die elektrische Energieversorgung mit ihrer vorzuhaltenden Infrastruktur vor wachsenden Herausforderungen. Beispielsweise wird die Installation neuer Ladepunkte innerhalb eines bestehenden Objektes häufig mit einer Ertüchtigung der lokalen elektrischen Infrastruktur und folglich mit zusätzlichen Investitionskosten verbunden sein. Zudem führt das elektrische Laden der Elektrofahrzeuge zu neuen Lastmustern, so dass sich für ein betreffendes Objekt der bisher bekannte elektrische Lastgang des Netzanschlusspunktes signifikant ändert. Im unvorteilhaften Fall einer ungesteuerten Parallelladung von mehreren Elektrofahrzeugen kann es zeitweilig zu einem erheblichen höheren Viertelstundenleistungsbedarf kommen, sodass sich dementsprechend die leistungsbezogenen Kostenanteile und somit auch die gesamten Energiebezugskosten für das betreffende Objekt erhöhen. Diesem Defizit können Ansätze zur gesteuerten und koordinierten Nachladung von Elektrofahrzeugen entgegenwirken, die sowohl eine Minimierung der Installations-als auch der Betriebskosten in Aussicht stellen. Im Rahmen des Beitrages werden konventionelle Methoden zum Last-bzw. Leistungsmanagement für Elektrofahrzeuge mit neuartigen Optimierungsansätzen gegenübergestellt, analysiert und verglichen.

description: A network of switches controlled by Boolean variables can be represented as a system of Boolean equations. The solution of this system gives a symbolic description of the conducting paths in the network. Gaussian elimination provides an efficient technique for solving sparse systems of Boolean equations. For the class of networks that arise when analyzing digital metal-oxide semiconductor (MOS) circuits, a simple pivot selection rule guarantees that most s-switch networks encountered in practice can be solved with O(s) operations. When represented by a directed acyclic graph, the set of Boolean formulas generated by the analysis has total size bounded by the number of operations required by the Gaussian elimination. This paper presents the mathematical basis for systems of Boolean equations, their solution by Gaussian elimination, and data structures and algorithms for representing and manipulating Boolean formulas.

description: In the realm of quantum information theory, the detection and quantification of quantum entanglement stand as paramount tasks. The relative entropy of entanglement (REE) serves as a prominent measure of entanglement, with extensive applications spanning numerous related fields. The positive partial transpose (PPT) criterion, while providing an efficient method for the computation of REE, unfortunately, falls short when dealing with bound entanglement. In this study, we propose a method termed "pure bosonic extension" to enhance the practicability of $k$-bosonic extensions, which approximates the set of separable states from the "outside", through a hierarchical structure. It enables efficient characterization of the set of $k$-bosonic extendible states, facilitating the derivation of accurate lower bounds for REE. Compared to the Semi-Definite Programming (SDP) approach, such as the symmetric/bosonic extension function in QETLAB, our algorithm supports much larger dimensions and higher values of extension $k$.

Ti-6Al-4V

description: Die zunehmende Prozesssicherheit und Verbreitung von additiven Fertigungsverfahren führt zu einem stetig wachsenden industriellen Interesse. Neben der Verwendung als individuelle Designelemente treten verstärkt Anwendungen in den Vordergrund, bei denen additiv gefertigte Bauteile wiederkehrenden mechanischen Belastungen ausgesetzt sind. Insbesondere für sicherheitsrelevante Anwendungsfälle ist ein umfassendes Verständnis der strukturellen Eigenschaften von entscheidender Bedeutung. Aus diesem Grund sind additiv gefertigte Werkstoffe zu einem Schlüsselthema der zerstörungsfreien und zerstörenden Werkstoffprüfung geworden. Während das Festigkeitspotential auf Basis von Zugversuchsergebnissen vielversprechend erscheint, dämpfen Ermüdungsversuche die allgemeinen Erwartungen teilweise erheblich. Bei zyklischen mechanischen Belastungen wirken insbesondere prozesstechnisch nicht vermeidbare Ungänzen, wie mikroskopische Anbindungsfehler oder Mikroporen versagenskritisch. Gezielte Wärmebehandlungen können die Zähigkeit und somit die Defekttoleranz des Werkstoffes signifikant beeinflussen, wodurch die Belastbarkeit gezielt verbessert werden kann. Dieser Beitrag präsentiert umfangreiche experimentelle Ermüdungsversuche an additiv hergestelltem Ti-6Al-4V, die im Rahmen des Verbundprojektes AMTwin erarbeitet wurden. Es werden vielfältige Einflussgrößen auf die Belastbarkeit vorgestellt und bewertet. Dazu zählen neben dem Wärmebehandlungszustand des Werkstoffes auch der verwendete AM-Anlagentyp und deren spezifische Prozessparameter sowie die Belastungsrichtung. Die ertragbare Belastungshöhe zeigt eine direkte Abhängigkeit zu mikroskopischen Unregelmäßigkeiten und zum Wärmebehandlungszustand. Es zeigen sich gleichzeitig aber auch unerwartete Unterschiede zwischen nominell gleichen Versuchsreihen. Die aufgetretenen Besonderheiten im Ermüdungsverhalten erschweren eine Vorhersage der Belastbarkeit deutlich. Dieser Aspekt wird anhand eines erweiterten „Murakami“-Auswerteansatzes vorgestellt, bei dem eine direkte Korrelation zwischen der vorhandenen Defektpopulation und der zu erwartenden Lebensdauer beschrieben wird. Die Anwendbarkeit einer Erweiterung dieses Vorhersagekonzeptes auf Leichtmetall-Legierungen durch Noguchi wird ebenfalls thematisiert und anhand der erzielten Ergebnisse bei Ti-6Al-4V bewertet. Die erzielten Ergebnisse verdeutlichen das komplexe Zusammenspiel zwischen dem Fertigungsprozess, der Mikrostruktur und der resultierenden mechanischen Eigenschaften bei der additiven Fertigung. Eine zuverlässige Vorhersage der Ermüdungsfestigkeit von additiv hergestellten Strukturen erscheint nach wie vor schwierig und kann nur mit Hilfe von detaillierten und konsistenten Informationen zum Herstellungsprozess und der Werkstoffstruktur erreicht werden.
Dynamics of Bloch vector in thermal Jaynes-Cummings model

description: In this paper, we investigate the dynamics of the Bloch vector of a single two-level atom which interacts with a single quantized electromagnetic field mode according to the Jaynes-Cummings model, where the field is initially prepared in a thermal state. The time evolution of the Bloch vector S(t) seems to be in complete disorder because of the thermal distribution of the initial state of the field. Both the norm and the direction of S(t) oscillate hard and their periods seem infinite. We observe that the trajectory of the time evolution of S(t) in the two- or three-dimensional space does not form a closed path. To remove the fast frequency oscillation from the trajectory, we take the time-average of the Bloch vector S(t). We examine the histogram of {S_{z}(nΔt)|n=0,1,...,N} for small Δt and large N. It represents an absolute value of a derivative of the inverse function of S_{z}(t). (When the inverse function of y=S_{z}(t) is a multi-valued function, the histogram represents a summation of the absolute values of its derivatives at points whose real parts are equal to y on the Riemann surface.) We examine the dependence of the variance of the histogram on the temperature of the field. We estimate the lower bound of the entanglement between the atom and the field.

description: We propose a systematic and efficient quantum circuit composed solely of Clifford gates for simulating the ground state of the surface code model. This approach yields the ground state of the toric code in $\lceil 2L+2+log_{2}(d)+\frac{L}{2d} \rceil$ time steps, where $L$ refers to the system size and $d$ represents the maximum distance to constrain the application of the CNOT gates. Our algorithm reformulates the problem into a purely geometric one, facilitating its extension to attain the ground state of certain 3D topological phases, such as the 3D toric model in $3L+8$ steps and the X-cube fracton model in $12L+11$ steps. Furthermore, we introduce a gluing method involving measurements, enabling our technique to attain the ground state of the 2D toric code on an arbitrary planar lattice and paving the way to more intricate 3D topological phases.

description: Non-ATPase regulatory subunits (Rpns) are components of the 26S proteasome involved in polyubiquitinated substrate recognition and deubiquitination in eukaryotes. Here, we identified 15 homologues sequences of Rpn and associated genes by searching the genome and transcriptome databases of the brown planthopper, Nilaparvata lugens, a hemipteran rice pest. Temporospatial analysis showed that NlRpn genes were significantly highly expressed in eggs and ovaries but were less-highly expressed in males. RNA interference (RNAi)-mediated depletion of NlRpn genes decreased the proteolytic activity of proteasome and impeded the transcription of lipase and vitellogenin genes in the fat bodies and ovaries in adult females, and reduced the triglyceride content in the ovaries. Decrease of the proteolytic activity of the proteasome via knockdown of NlRpns also inhibited the transcription of halloween genes, including NlCYP307A2, NlCYP306A2 and NlCYP314A1, in the 20-hydroxyecdysone (20E) biosynthetic pathway in the ovaries, reduced 20E production in adult females, and impaired ovarian development and oocyte maturation, resulting in reduced fecundity. These novel findings indicate that the proteolytic activity of the proteasome is required for female reproductive processes in N. lugens, thus furthering our understanding of the reproductive and developmental strategies in insects.

description: WKB approximation methods are applied to the case of a massive scalar field around a 5-dimensional Reissner-Nordström black hole. The divergences are explicitly isolated and the cancellation against the Schwinger-De Witt counter-terms proven. The resulting finite quantity is evaluated for different values of the free parameters, namely the black hole mass and charge, and the scalar field mass. We thus extend our previous results on quantum vacuum polarization effects for uncharged asymptotically flat higher dimensional black holes to electrically charged black holes.

description: The de Haas-van Alphen effect was observed in the underdoped cuprate YBa$_2$Cu$_3$O$_{6.5}$ via a torque technique in pulsed magnetic fields up to 59 T. Above an irreversibility field of $\sim$30 T, the magnetization exhibits clear quantum oscillations with a single frequency of 540 T and a cyclotron mass of 1.76 times the free electron mass, in excellent agreement with previously observed Shubnikov-de Haas oscillations. The oscillations obey the standard Lifshitz-Kosevich formula of Fermi-liquid theory. This thermodynamic observation of quantum oscillations confirms the existence of a well-defined, close and coherent, Fermi surface in the pseudogap phase of cuprates.

The investigation reveals that each area of the organization has its own specific needs; however, a well-being plan can be implemented that aligns with the categories constructed from the narratives of the employees themselves, with the aim of recognizing and addressing aspects such as emotional salary, actions for personal/professional development, and the establishment of a culture of health in the workplace.
Electron-hole asymmetry of quantum collective excitations in high-$T_c$ copper oxides

description: We carry out a systematic study of collective spin- and charge excitations for the canonical single-band Hubbard, $t$-$J$-$U$, and $t$-$J$ models of high-temperature copper-oxide superconductors, both on electron- and hole-doped side of the phase diagram. Recently developed variational wave function approach, combined with the expansion in inverse number of fermionic flavors, is employed. All three models exhibit a substantial electron-hole asymmetry of magnetic excitations, with a robust paramagnon emerging for hole-doping, in agreement with available resonant inelastic $x$-ray scattering data for the cuprates. The $t$-$J$ model yields additional high-energy peak in the magnetic spectrum that is not unambiguously identified in spectroscopy. For all considered Hamiltonians, the dynamical charge susceptibility contains a coherent mode for both hole- and electron doping, with overall bandwidth renormalization controlled by the on-site Coulomb repulsion. Away from the strong-coupling limit, the antiferromagnetic ordering tendency is more pronounced on electron-doped side of the phase diagram.

description: Writing concurrent applications is extremely challenging, not only in terms of producing bug-free and maintainable software, but also for enabling developer productivity. In this article we present the Æminium concurrent-by-default programming language. Using Æminium programmers express data dependencies rather than control flow between instructions. Dependencies are expressed using permissions, which are used by the type system to automatically parallelize the application. The Æminium approach provides a modular and composable mechanism for writing concurrent applications, preventing data races in a provable way. This allows programmers to shift their attention from low-level, error-prone reasoning about thread interleaving and synchronization to focus on the core functionality of their applications. We study the semantics of Æminium through μÆminium, a sound core calculus that leverages permission flow to enable concurrent-by-default execution. After discussing our prototype implementation we present several case studies of our system. Our case studies show up to 6.5X speedup on an eight-core machine when leveraging data group permissions to manage access to shared state, and more than 70% higher throughput in a Web server application.

Magnetic reflections are observed below each transition indicating that the magnetic interactions in LuFe2O4 are 3-dimensional (3D) in character. The magnetic structure is refined as a ferrimagnetic spin configuration below the 240 K transition. While 3D magnetic correlations persists below 175 K, a significant broadening of the magnetic peaks is observed along with the build up of a diffuse component to the magnetic scattering.

This implies that there are no static soliton spacetimes and completes the classification of static non-extremal black holes in this theory. In particular, these results establish that there are no asymptotically flat static spacetimes with non-trivial topology, with or without a black hole, in Einstein-Maxwell theory.

description: This paper focuses on the production of bio-diesel from low cost feed stock CucumisSativus seed oil using MnCO3 as a Green (Nanosized) catalyst through transesterification process and investigating the effects of process parameters on bio-diesel yield. The optimum parameters for maximum bio-diesel yields were found to be methanol/oil molar ratio of 1:1, catalyst concentration of 1 wt% of oil, at the temperature of 65°C and reaction time 3 hours (180 min). The maximum bio-diesel yield at the optimum condition was 86%. Crystalline manganese carbonate was found to be environmentally friendly, easy to handle and non-corrosive green catalyst for the production of biodiesel from cucumber seed oil. The enhancement of the parameters are possible because of the Nano nature of the catalyst used. The results demonstrated high potential of producing economically viable biodiesel from low cost feed stocks with proper optimization of the process parameters.

description: In this study a robust and alternative method of gold quality identification is presented. Four different Karats of gold from different origins were used for investigation. Comparison was made between the traditional Quantum Karat meter and Laser Induced Breakdown spectra to compare their quality. The advantage of the new technique over the Karat meter is that the different types of impurities that are found in the gold were clearly identified and their quantities/percentage tabulated. The method is also robust in such a way that it is calibration free. During the experiment, the most resonant atomic line and ionic line of emission of gold were taken at 267.597 nm and at 226.363nm, respectively, in order to reduce the impact of the back ground on the spectral intensities. The experimental result indicated that both atomic and ionic lines of emission were found in very good agreement with Quantum Karat meter and can reliably be applied as an alternative method of quality control or in a place where such equipment is not available. It was found that the ionic to background and atomic to back ground ratios as well as their normalized intensities were in excellent match with the results from the measured quantum Karat meter.

description: Gross, Mansour and Tucker introduced the partial-twuality polynomial of a ribbon graph. Chumutov and Vignes-Tourneret posed a problem: it would be interesting to know whether the partial duality polynomial and the related conjectures would make sense for general delta-matroids. In this paper we consider analogues of partial-twuality polynomials for delta-matroids. Various possible properties of partial-twuality polynomials of set systems are studied. We discuss the numerical implications of partial-twualities on a single element and prove that the intersection graphs can determine the partial-twuality polynomials of bouquets and normal binary delta-matroids, respectively. Finally, we give a characterization of vf-safe delta-matroids whose partial-twuality polynomials have only one term.

description: It has been recently observed that a scalar field with Robin boundary conditions (RBCs) can trigger both a superradiant and a bulk instability for a BTZ black hole (BH). To understand the generality and scrutinize the origin of this behavior, we consider here the superradiant instability of a Kerr BH confined either in a mirror-like cavity or in AdS space, triggered also by a scalar field with RBCs. These boundary conditions are the most general ones that ensure the cavity/AdS space is an isolated system, and include, as a particular case, the commonly considered Dirichlet boundary conditions (DBCs). Whereas the superradiant modes for some RBCs differ only mildly from the ones with DBCs, in both cases we find that as we vary the RBCs, the imaginary part of the frequency may attain arbitrarily large positive values. We interpret this growth as being sourced by a bulk instability of both confined geometries when certain RBCs are imposed to either the mirror-like cavity or the AdS boundary, rather than by energy extraction from the BH, in analogy with the BTZ behavior.

description: This study described socio-economic effects of foreign direct investment (FDI) on local community in Ethiopia focusing on two themes—labor and landholders. The study used both qualitative and quantitative methods. Qualitatively, the data were gathered from landholders, local elders and labors through semi structured interviews and focus group discussions. Quantitatively, sample of 120 participants was selected from landholders and labors purposively. The finding of this study revealed that FDI has both positive and negative effects on local labors. The positive effects are: creation of job opportunity; increment of real wage; transfer of knowledge and technology. In contrast, the negative effects are: wage difference between skilled labors, and absence of standardized rules and regulations to employ local labors. On the other hand, FDI has negative effect on landholders—inadequacy of compensation; absence of enough precondition to resettle the landholders; expropriation of landholders from their lands; loss of diversified mode of income and become dependent on only paid compensation; and addiction of youths to chat and alcohol. The researcher recommended that the landholders should be informed by neutral organization such as civil society organization about the investment, and adequate compensation should be paid for them.

description: Diesel engines with their high thermal efficiency and fuel economy are very much successful in commercial applications compared to their counterpart gasoline engines. The emissions like HC and CO from diesel engines are less compared to gasoline engines because they run mostly with lean mixtures. But due to heterogeneous combustion NOx and smoke emissions from Diesel engines is high. Due to contradicting requirements for the reduction of NOx and smoke, the tradeoff between NOx and smoke emission without compromising fuel economy is a big challenge being faced by automotive industries and researchers in the field. Also to have sustainable civilization, there is a need to find eco friendly and renewable alternative fuel to petro diesel to conserve fast depleting petroleum resources and to minimize environmental pollution. Biodiesel produced from non-edible feed stock is found to be a good alternative to petro diesel. It is observed that the formation of NOx is very much dependent on the peak temperature in the combustion chamber. Various types of techniques are being tried by the researchers to reduce high NOx emission from usage of biodiesel blended fuel in diesel engines. The techniques used are like dilution using EGR, injection of water, retardation of injection timing etc. With the development of CRDI systems split and multiple injection strategy attracting the attention of researchers as a promising technique in reducing the NOx emissions. In this work an attempt is made to study the effect of retardation of injection timing of a selected multiple injection with pilot-main-post strategy. The selected strategy is with 10% pilot fuel quantity with a dwell of 10 CAD and closely coupled fixed quantity of 0.5 mg post injection with 3 CAD after main injection. The main injection timing along with pilot and post was retarded from the recommended 23o bTDC in steps of 3 degrees. It is observed that the combination of multiple injection and retardation of injection reduced NOx emissions effectively without compromising power output and thermal efficieny.

description: Obtaining large samples of galaxy clusters is important for cosmology, since cluster counts as a function of redshift and mass can constrain the parameters of our Universe. They are also useful to understand the formation and evolution of clusters. We develop an improved version of the AMACFI cluster finder (now AMASCFI) and apply it to the 154 deg2 of the Canada France Hawaii Telescope Legacy Survey (CFHTLS) to obtain a catalogue of 1371 cluster candidates with mass M200 > 10^14 Msun and redshift z < 0.7. We derive the selection function of AMASCFI from the Millennium simulation, and cluster masses from a richness-mass scaling relation built from matching our candidates with X-ray detections. We study the evolution of these clusters with mass and redshift by computing the i'-band galaxy luminosity functions (GLFs) for the early (ETGs) and late-type galaxies (LTGs). This sample is 90% pure and 70% complete, therefore our results are representative the cluster population in these redshift and mass ranges. We find an increase of both the ETG and LTG faint populations with decreasing redshift (with Schechter slopes alpha_ETG = -0.65 +/- 0.03 at z=0.6 and alpha_ETG = -0.79 +\- 0.02 at z=0.2) and also a decrease of the LTG bright end, but not of the ETG's. Our large sample allows us to break the degeneracy between mass and redshift, finding that the redshift evolution is more pronounced in high-mass clusters, but that there is no significant dependence of the faint end on mass for a given redshift. These results show that the cluster red sequence is mainly formed at redshift z > 0.7, and that faint ETGs continue to enrich the red sequence through quenching of brighter LTGs at z < 0.7. The efficiency of this quenching is higher in large-mass clusters while the accretion rate of faint LTGs is lower as the more massive clusters have already emptied most of their environment at higher redshifts.
