description: Open clusters (OCs) are crucial for studying the formation and evolution of the Galactic disc. However, the lack of a large number of OCs analyzed homogeneously hampers the investigations about chemical patterns and the existence of Galactocentric radial and vertical gradients, or an age-metallicity relation. To overcome this, we have designed the Open Cluster Chemical Abundances from Spanish Observatories survey (OCCASO). We aim to provide homogeneous radial velocities, physical parameters and individual chemical abundances of six or more Red Clump stars for a sample of 25 old and intermediate-age OCs visible from the Northern hemisphere. To do so, we use high resolution spectroscopic facilities (R> 62,000) available at Spanish observatories. We present the motivation, design and current status of the survey, together with the first data release of radial velocities for 77 stars in 12 OCs, which represents about 50% of the survey. We include clusters never studied with high-resolution spectroscopy before (NGC~1907, NGC~6991, NGC~7762), and clusters in common with other large spectroscopic surveys like the Gaia-ESO Survey (NGC~6705) and APOGEE (NGC~2682 and NGC~6819). We perform internal comparisons between instruments to evaluate and correct internal systematics of the results, and compare our radial velocities with previous determinations in the literature, when available. Finally, radial velocities for each cluster are used to perform a preliminar kinematic study in relation with the Galactic disc.

Vocal Source Separation for Carnatic Music
Creators: name: Adithi Shankar Sivasankar
Publisher: name: Zenodo
Year: 2023
Subjects: Carnatic Music; Source Separation, Melodic analysis.

description: Carnatic Music is a Classical music form that originates from the South of India and is extremely varied from Western genres. Music Information Retrieval (MIR) has predominantly been used to tackle problems in western musical genres and cannot be adapted to non western musical styles like Carnatic Music due to the fundamental difference in melody, rhythm, instrumentation, nature of compositions and improvisations.
 Due to these conceptual differences emerged MIR tasks specific for the use case of Carnatic Music. Researchers have constantly been using domain knowledge and technology driven ideas to tackle tasks like Melodic analysis, Rhythmic analysis and Structural segmentation. Melodic analysis of Carnatic Music has been a cornerstone in MIR research and heavily relies on the singing voice because the singer offers the main melody. The problem is that the singing voice is not isolated and has melodic, percussion and drone instruments as accompaniment. Separating the singing voice from the accompanying instruments usually comes with issues like bleeding of the accompanying instruments and loss of melodic information. This in turn has an adverse effect on the melodic analysis. The datasets used for Carnatic-MIR are concert recordings of different artistes with accompanying instruments and there is a lack of clean isolated singing voice tracks. Existing Source Separation models are trained extensively on multi-track audio of the rock and pop genre and do not generalize well for the use case of Carnatic music. How do we improve Singing
 Voice Source Separation for Carnatic Music given the above constraints? In this work, the possible contributions to mitigate the existing issue are ; 1) Creating a dataset of isolated Carnatic music stems. 2) Reusing multi-track audio with bleeding from the Saraga dataset. 3) Retraining and fine tuning existing State of the art Source Separation models. We hope that this effort to improve Source Separation
 for Carnatic Music can help overcome existing shortcomings and generalize well for Carnatic music datasets in the literature and in turn improve melodic analysis of this music culture.

description: Route planning for multiple Unmanned Aerial Vehicles (UAVs) is a series of translation and rotational steps from a given start location to the destination goal location. The goal of the route planning problem is to determine the most optimal route avoiding any collisions with the obstacles present in the environment. Route planning is an NP-hard optimization problem. In this paper, a newly proposed Salp Swarm Algorithm (SSA) is used, and its performance is compared with deterministic and other Nature-Inspired Algorithms (NIAs). The results illustrate that SSA outperforms all the other meta-heuristic algorithms in route planning for multiple UAVs in a 3D environment. The proposed approach improves the average cost and overall time by 1.25% and 6.035% respectively when compared to recently reported data. Route planning is involved in many real-life applications like robot navigation, self-driving car, autonomous UAV for search and rescue operations in dangerous ground-zero situations, civilian surveillance, military combat and even commercial services like package delivery by drones.

description: Electronic correlation energies from the random-phase approximation converge slowly with respect to the plane wave basis set size. We study the conditions, under which a short-range local density functional can be used to account for the basis set incompleteness error. Furthermore, we propose a one-shot extrapolation scheme based on the Lindhard response function of the homogeneous electron gas. The different basis set correction methods are used to calculate equilibrium lattice constants for prototypical solids of different bonding types.

description: The unique properties of spin-polarized surface or edge states in topological insulators (TIs) make these quantum coherent systems interesting from the point of view of both fundamental physics and their implementation in low power spintronic devices. Here we present such a study in TIs, through tunneling and noise spectroscopy utilizing TI/Al$_2$O$_3$/Co tunnel junctions with bottom TI electrodes of either Bi$_2$Te$_3$ or Bi$_2$Se$_3$. We demonstrate that features related to the band structure of the TI materials show up in the tunneling conductance and even more clearly through low frequency noise measurements. The bias dependence of 1/f noise reveals peaks at specific energies corresponding to band structure features of the TI. TI tunnel junctions could thus simplify the study of the properties of such quantum coherent systems, that can further lead to the manipulation of their spin-polarized properties for technological purposes.

Subjects: Rhythmspace, JUCE framework, Low-dimensional Space Evaluation.

description: In modern computer-based music production, vast musical data libraries are essential. However, their presentation via subpar interfaces can hinder creativity, complicating the selection of ideal sequences. While low-dimensional space solutions have been suggested, their evaluations in real-world music production remain limited. In this study, we focus on Rhythmspace, a two-dimensional platform tailored for the exploration and generation of drum patterns in symbolic MIDI format. Our primary objectives encompass two main aspects: first, the evolution of Rhythmspace into a VST tool specifically designed for music production settings, and second, a thorough evaluation of this tool to ascertain its performance and applicability within the music production scenario. The tool’s development necessitated transitioning the existing Rhythmspace, which operates in Puredata and Python, into a VST compatible with Digital Audio Workstations (DAWs) using the JUCE(C++) framework. Our evaluation encompassed a series of experiments, starting with a composition test where participants crafted drum sequences followed by a listening test, wherein participants ranked the sequences from the initial experiment. The results show that Rhythmspace and similar tools are beneficial, facilitating the exploration and creation of drum patterns in a user-friendly and intuitive manner, and enhancing the creative process for music producers. These tools not only streamline the drum sequence generation but also offer a fresh perspective, often serving as a source of inspiration in the dynamic realm of electronic music production.

title: Mechanistic Investigation of a Non-Catalytic Gating Residue in NADH:Quinone Oxidoreductase from Pseudomonas aeruginosa PA01
Creators: name: Moni, Bilkis Mehrin
Publisher: name: Georgia State University

description:
NADH:quinone oxidoreductase from Pseudomonas aeruginosa PAO1 (NQO, PA1024, EC 1.6.5.9) is a recently reclassified flavin-dependent enzyme that catalyzes the two-electron reduction of a wide variety of quinones to hydroquinone using NADH as an electron donor. The two-electron reduction of quinone plays a detoxification role in P. aeruginosa by avoiding the formation of semiquinone radicals. The previously solved crystal structure of the NQO demonstrated that the substrate-binding site of NQO is formed by a small entrance consisting of a flexible ?? loop 3 (residue 75-86). Q80 in loop 3 switches between an open conformation without NAD+ bound and a close conformation with NAD+ bound. In this study, Q80 was mutated to glycine, leucine, or glutamate through site-directed mutagenesis to investigate the role of Q80 in binding and catalysis in NQO. The results showed that Q80 residue participates in substrate NADH binding in the active site of NQO.

description:
Near-infrared (NIR) dyes have attracted attention in research and clinical applications due to their enhanced optical properties, pharmacokinetics, toxicokinetic, and feasible structure modifications. Current intensive research explores NIR hemicyanine dyes based on their improved sensitivity, stability, and photophysical properties as contrast agents and sensing probes. Herein we focus on designing, synthesizing, and analyzing hemicyanine dyes as fluorophores for photoacoustic imaging. By integrating various functional groups on their chemical scaffolds, the hemicyanine dyes can improve their photoacoustic signal and absorbance wavelength to advance their imaging properties. The absorption wavelengths of the synthesized hemicyanine dyes are within the range of 680  720 nm. In addition, our initial screening revealed that hemicyanine dyes modified with heavy atoms such as chlorine and bromine, rotatable bonds, hydrophobic moieties and charged groups provide better optoacoustic signals.
Automatic coarsening in Algebraic Multigrid utilizing quality measures for matching-based aggregations

description: In this paper, we discuss the convergence of an Algebraic MultiGrid (AMG) method for general symmetric positive-definite matrices. The method relies on an aggregation algorithm, named \emph{coarsening based on compatible weighted matching}, which exploits the interplay between the principle of compatible relaxation and the maximum product matching in undirected weighted graphs. The results are based on a general convergence analysis theory applied to the class of AMG methods employing unsmoothed aggregation and identifying a quality measure for the coarsening; similar quality measures were originally introduced and applied to other methods as tools to obtain good quality aggregates leading to optimal convergence for M-matrices. The analysis, as well as the coarsening procedure, is purely algebraic and, in our case, allows an \emph{a posteriori} evaluation of the quality of the aggregation procedure which we apply to analyze the impact of approximate algorithms for matching computation and the definition of graph edge weights. We also explore the connection between the choice of the aggregates and the compatible relaxation convergence, confirming the consistency between theories for designing coarsening procedures in purely algebraic multigrid methods and the effectiveness of the coarsening based on compatible weighted matching. We discuss various completely automatic algorithmic approaches to obtain aggregates for which good convergence properties are achieved on various test cases.

description: Recently a remarkable connection has been proposed between the fluctuating hydrodynamic equations of a one-dimensional fluid and the Kardar-Parizi-Zhang (KPZ) equation for interface growth. This connection has been used to relate equilibrium correlation functions of the fluid to KPZ correlation functions. Here we use this connection to compute the exact cumulant generating function for energy current in the fluid system. This leads to exact expressions for all cumulants and in particular to universal results for certain combinations of the cumulants. As examples, we consider two different systems which are expected to be in different universality classes, namely a hard particle gas with Hamiltonian dynamics and a harmonic chain with momentum conserving stochastic dynamics. Simulations provide excellent confirmation of our theory.

description: Which statistical features distinguish a meaningful text (possibly written in an unknown system) from a meaningless set of symbols? Here we answer this question by comparing features of the first half of a text to its second half. This comparison can uncover hidden effects, because the halves have the same values of many parameters (style, genre {\it etc}). We found that the first half has more different words and more rare words than the second half. Also, words in the first half are distributed less homogeneously over the text in the sense of of the difference between the frequency and the inverse spatial period. These differences hold for the significant majority of several hundred relatively short texts we studied. The statistical significance is confirmed via the Wilcoxon test. Differences disappear after random permutation of words that destroys the linear structure of the text. The differences reveal a temporal asymmetry in meaningful texts, which is confirmed by showing that texts are much better compressible in their natural way (i.e. along the narrative) than in the word-inverted form. We conjecture that these results connect the semantic organization of a text (defined by the flow of its narrative) to its statistical features.

Dabei stellt sich die Frage, ob – trotz jeweils unterschiedlicher Konzeptualisierungen und Operationalisierungen mathematikdidaktischer Kompetenzen – die Konstruktvalidität gewahrt werden kann. Ein erster Ansatz dazu wird in diesem Beitrag vorgestellt: Die Projekte KomMa (Jenßen et al. 2015) und AnschlussM (Carle & Wittmann 2015), die unabhängig voneinander geplant und durchgeführt wurden, zielen beide unter anderem auf das professionelle Wissen von ErzieherInnen zum Lehren und Lernen von Mathematik. Es liegt deshalb nahe, in einem Anschlussprojekt die Konstruktvalidität der Instrumente an einer gemeinsamen Stichprobe zu prüfen.

description: In this paper we study a wide range of variants for computing the (discrete and continuous) Fréchet distance between uncertain curves. We define an uncertain curve as a sequence of uncertainty regions, where each region is a disk, a line segment, or a set of points. A realisation of a curve is a polyline connecting one point from each region. Given an uncertain curve and a second (certain or uncertain) curve, we seek to compute the lower and upper bound Fréchet distance, which are the minimum and maximum Fréchet distance for any realisations of the curves. We prove that both the upper and lower bound problems are NP-hard for the continuous Fréchet distance in several uncertainty models, and that the upper bound problem remains hard for the discrete Fréchet distance. In contrast, the lower bound (discrete and continuous) Fréchet distance can be computed in polynomial time. Furthermore, we show that computing the expected discrete Fréchet distance is #P-hard when the uncertainty regions are modelled as point sets or line segments. The construction also extends to show #P-hardness for computing the continuous Fréchet distance when regions are modelled as point sets. On the positive side, we argue that in any constant dimension there is a FPTAS for the lower bound problem when $Δ/ δ$ is polynomially bounded, where $δ$ is the Fréchet distance and $Δ$ bounds the diameter of the regions. We then argue there is a near-linear-time 3-approximation for the decision problem when the regions are convex and roughly $δ$-separated. Finally, we also study the setting with Sakoe--Chiba time bands, where we restrict the alignment between the two curves, and give polynomial-time algorithms for upper bound and expected discrete and continuous Fréchet distance for uncertainty regions modelled as point sets.

description: El presente estudio tiene como objetivo realizar una evaluación cualitativa y diagnostico patológico de la Casa Cural de la Iglesia de Santo Toribio de Mogrovejo de Cartagena de Indias. Este estudio es de vital importancia debido a que una cantidad considerable de elementos estructurales de la edificación se encuentran fisurados y en colapso inminente. A partir de los resultados de esta investigación se tomaran medidas para iniciar acciones de rehabilitación con el objetivo de conservar la estructura de la casa. Inicialmente se realizó una inspección visual detallada y una serie de ensayos no destructivos del inmueble, comprendiendo un estudio de tipo no experimental, lo cual permitió conocer las verdaderas causas de las fallas presentadas en la vivienda. En general, se encontraron patologías características de las construcciones de tipo republicano y edificaciones del sector: los elementos de madera de la cubierta presentaban ataque de xilófagos, también humedad considerable en los muros de mampostería estructural y no estructural. Se encontró falta de recubrimiento y corrosión en las losas de concreto reforzado, de igual forma en las columnas circulares de la casa. Ante los resultados obtenidos se determinó que las losas de concreto deben ser demolidas para evitar accidentes graves, ya que no solo presentaban las patologías mencionados, sino que registraban deflexiones considerables. De igual forma, algunos muros por la dimensión de las grietas también deben ser demolidos. Elementos como las columnas circulares alguno de mampostería estructural dieron buenas resistenciasen los ensayos, y pueden ser útiles en el proceso de rehabilitación. Aunque son muchas las patologías encontradas, no son lo suficientemente graves para constituirse como la causa de los movimientos que presentó la edificación en el último año. Por esto, y conociendo la situación de otras viviendas del sector, la obra Adecuación del Bastión de Reyes que aun se encuentra en construcción desde enero del año pasado, se constituye como la principal causa de los movimientos

description: We provide a criterion for a coherent sheaf to be an Ulrich sheaf in terms of a certain bilinear form on its global sections. When working over the real numbers we call it a positive Ulrich sheaf if this bilinear form is symmetric or hermitian and positive definite. In that case our result provides a common theoretical framework for several results in real algebraic geometry concerning the existence of algebraic certificates for certain geometric properties. For instance, it implies Hilbert's theorem on nonnegative ternary quartics, via the geometry of del Pezzo surfaces, and the solution of the Lax conjecture on plane hyperbolic curves due to Helton and Vinnikov.

description: As pervasive data collection and powerful algorithms increasingly shape children's experience of the world and each other, their ability to interrogate computational algorithms has become crucially important. A growing body of work has attempted to articulate a set of "literacies" to describe the intellectual tools that children can use to understand, interrogate, and critique the algorithmic systems that shape their lives. Unfortunately, because many algorithms are invisible, only a small number of children develop the literacies required to critique these systems. How might designers support the development of critical algorithmic literacies? Based on our experience designing two data programming systems, we present four design principles that we argue can help children develop literacies that allow them to understand not only how algorithms work, but also to critique and question them.

description: The existence of global weak solutions to a parabolic energy-transport system in a bounded domain with no-flux boundary conditions is proved. The model can be derived in the diffusion limit from a kinetic equation with a linear collision operator involving a non-isothermal Maxwellian. The evolution of the local temperature is governed by a heat equation with a source term that depends on the energy of the distribution function. The limiting model consists of cross-diffusion equations with an entropy structure. The main difficulty is the nonstandard degeneracy, i.e., ellipticity is lost when the fluid density or temperature vanishes. The existence proof is based on a priori estimates coming from the entropy inequality and the $H^{-1}$ method and on techniques from mathematical fluid dynamics (renormalized formulation, div-curl lemma).

description: Local estimates of HIV-prevalence provide information that can be used to target interventions and consequently increase the efficiency of the resources. This closer-to-optimal allocation can lead to better health outcomes, including the control of the disease spread, and for more people. Producing reliable estimates at smaller geographical levels can be challenging and careful consideration of the nature of the data and the epidemiologic rational is needed. In this paper, we use the DHS data phase V to estimate HIV prevalence at the first-subnational level in Kenya, Tanzania, and Mozambique. We fit the data to a spatial random effect intrinsic conditional autoregressive (ICAR) model to smooth the outcome. We also use a sampling specification from a multistage cluster design. We found that Nyanza (P=14.2%) and Nairobi (P=7.8%) in Kenya, Iringa (P=16.2%) and Dar es Salaam (P=10.1%) in Tanzania, and Gaza (P=13.7%) and Maputo City (P=12.7%) in Mozambique are the regions with the highest prevalence of HIV, within country. Our results are based on statistically rigorous methods that allowed us to obtain an accurate visual representation of the HIV prevalence in the subset of African countries we chose. These results can help in identification and targeting of high-prevalent regions to increase the supply of healthcare services to reduce the spread of the disease and increase the health quality of people living with HIV.

Campodea (Campodea) kasiki Rusek, 1964: 140, figs 57–77.
Diagnosis (Rusek 1964)
Body length 3.5 mm; short, smooth clothing setae; midle-sized, thin, barbed notal macrosetae with a few thin and long barbs; long smooth notal marginal setae; smooth marginal setae; 1+1 ma macrosetae on I–VII urotergites, 1+1 la, 1+1 lp on IV–VII urotergites, 3+3 lp on VIII urotergite and 5+5 lp on IX abdominal segment.
Taxonomic notes
Anatolian specimens quoted by Sendra et al. (2006) show some features that have not been described by Rusek (1964) (Supplementary file 2): epicuticle without microdenticles; 23–25 antennomeres with sensillum of the third antennomere in dorsal position; and one trochanteral sensillum. The female from Montenegro studied doesn’t have microsenticles and no trochanteral sensillum has been seen either, but the antennae are completely regenerated.
Habitat and distribution
Soil-dwelling species collected in three isolated regions, in the Tatra Mountains of Slovakia (Rusek 1964), at a single locality in Montenegro and in the central and eastern Anatolian Peninsula (Sendra et al. 2006).

description: We discuss a qubit weakly coupled to a finite-size heat bath (calorimeter) from the point of view of quantum thermodynamics. The energy deposited to this environment together with the state of the qubit provides a basis to analyze the heat and work statistics of this closed combined system. We present results on two representative models, where the bath is composed of two-level systems or harmonic oscillators, respectively. Finally, we derive results for an open quantum system composed of the above qubit plus finite-size bath, but now the latter is coupled to a practically infinite bath of the same nature of oscillators or two-level systems.

description: We propose an end-to-end learning approach to address deinterleaving of patterns in time series, in particular, radar signals. We link signal clustering problem to min-cost flow as an equivalent problem once the proper costs exist. We formulate a bi-level optimization problem involving min-cost flow as a sub-problem to learn such costs from the supervised training data. We then approximate the lower level optimization problem by self-attention based neural networks and provide a trainable framework that clusters the patterns in the input as the distinct flows. We evaluate our method with extensive experiments on a large dataset with several challenging scenarios to show the efficiency.

description: Attosecond light pulses in the extreme ultraviolet have drawn a great deal of attention due to their ability to interrogate electronic dynamics in real time. Nevertheless, to follow charge dynamics and excitations in materials, element selectivity is a prerequisite, which demands such pulses in the soft X-ray region, above 200 eV, to simultaneously cover several fundamental absorption edges of the constituents of the materials. Here, we experimentally demonstrate the exploitation of a transient phase matching regime to generate carrier envelope controlled soft X-ray supercontinua with pulse energies up to 2.9 +/- 0.1 pJ and a flux of (7.3 +/- 0.1)x10^7 photons/s across the entire water window and attosecond pulses with 13 as transform limit. Our results herald attosecond science at the fundamental absorption edges of matter by bridging the gap between ultrafast temporal resolution and element specific probing.

description: We present a lattice calculation of the neutron and proton electric dipole moments (EDM's) with $N_f=2+1$ flavors of domain-wall fermions. The neutron and proton EDM form factors are extracted from three-point functions at the next-to-leading order in the $θ$ vacuum of QCD. In this computation, we use pion masses 0.33 and 0.42 GeV and 2.7 fm$^3$ lattices with Iwasaki gauge action and a 0.17 GeV pion and 4.6 fm$^3$ lattice with I-DSDR gauge action, all generated by the RBC and UKQCD collaborations. The all-mode-averaging technique enables an efficient and high statistics calculation. Chiral behavior of lattice EDM's is discussed in the context of baryon chiral perturbation theory. In addition, we also show numerical evidence on relationship of three- and two-point correlation function with local topological distribution.

Planung und Erhebung statistischer Daten im Mathematikunterricht

description: Die Planung und Durchführung statistischer Erhebungen sind zwei bedeutende Phasen im Gesamtprozess einer statistischen Untersuchung und durch die nationalen Bildungsstandards verbindliche Unterrichtsinhalte der Sekundarstufen I & II (KMK 2003,S.16). Dennoch werden sie im Schulunterricht eher wenig thematisiert. Laut Pisa 2012 zeigen sich bis heute immer noch „relative Schwächen im Bereich der Unsicherheit und Daten. Hier zeichnet sich somit ein Ansatzpunkt für eine weitere Verbesserung mathematischer Kompetenz in Deutschland ab.“ (Pisa, 2012, S.82). Der Artikel stellt zum Beitragsthema Planung und Erhebung statistischer Daten im Mathematikunterricht erste Grundgedanken eines empirischen Studienvorhabens und ein normativ entwickeltes Planungs- und Entscheidungsmodell heraus – welches einen mögl. Handlungsablauf innerhalb einer statistischen Planungsphase wiedergibt. Das Hauptanliegen der Studie besteht darin, mittels des entworfenen theoretischen Planungs- und Entscheidungsmodells einen Rahmen zu schaffen, mit dessen Hilfe sich Schülerschwierigkeiten, Fehler und Lernstrategien beim statistischen Planen empirisch identifizieren lassen.
