description: Startups play a critical role in driving innovation, creating jobs, and promoting economic growth. They bring new and innovative ideas to market, disrupting existing markets and creating new ones. By introducing new products, services, and technologies, startups can increase productivity, efficiency, and consumer welfare. Startups are also important drivers of job creation, as they often require a range of skills and expertise, from product development to marketing and sales. They can provide talented and motivated individuals opportunities to build their careers and contribute to the economy. The Algerian government gives startups a particular interest to the startups. The aim of the paper is to show the importance of startups in the economy and the most obstacles that could face the startups to avoid theme in the future.

description: We generate and study an ensemble of isostatic jammed hard-sphere lattices. These lattices are obtained by compression of a periodic system with an adaptive unit cell containing a single sphere until the point of mechanical stability. We present detailed numerical data about the densities, pair correlations, force distributions, and structure factors of such lattices. We show that this model retains many of the crucial structural features of the classical hard-sphere model and propose it as a model for the jamming and glass transitions that enables exploration of much higher dimensions than are usually accessible.

description: Emotional availability in parent-child interactions fosters children’s socioemotional development. Little is known about the emotional availability of parents and children with profound motor disabilities and complex communication needs or the contributions of augmentative and alternative communication (AAC) to emotional availability. To begin addressing these gaps, this pilot study focused on three mothers and their children with spinal muscular atrophy Type 1 who could not speak and required AAC. The study used a mixed-methods design. Mother-child interactions were rated using the Emotional Availability Scales. Semi-structured in-depth interviews with the mothers were qualitatively analyzed. Emotional availability in mother-child dyads was adequate. In the interviews, mothers addressed significant challenges but described mainly typical parent-child relationships and adaptive child and mother coping attributable to the use of AAC. Results suggest that emotional availability is possible and can be facilitated by AAC, even with children with profound motor disabilities and limited ability to communicate needs and desires. The findings highlight the importance of targeting children’s socioemotional needs and parent-child emotional availability in AAC interventions with families of children with profound motor disabilities.

description: The history of southern Africa involved interactions between indigenous hunter-gatherers and a range of populations that moved into the region. Here we use genome-wide genetic data to show that there are at least two admixture events in the history of Khoisan populations (southern African hunter-gatherers and pastoralists who speak non-Bantu languages with click consonants). One involved populations related to Niger-Congo-speaking African populations, and the other introduced ancestry most closely related to west Eurasian (European or Middle Eastern) populations. We date this latter admixture event to approximately 900-1,800 years ago, and show that it had the largest demographic impact in Khoisan populations that speak Khoe-Kwadi languages. A similar signal of west Eurasian ancestry is present throughout eastern Africa. In particular, we also find evidence for two admixture events in the history of Kenyan, Tanzanian, and Ethiopian populations, the earlier of which involved populations related to west Eurasians and which we date to approximately 2,700 - 3,300 years ago. We reconstruct the allele frequencies of the putative west Eurasian population in eastern Africa, and show that this population is a good proxy for the west Eurasian ancestry in southern Africa. The most parsimonious explanation for these findings is that west Eurasian ancestry entered southern Africa indirectly through eastern Africa.

description: The aims of this study are to examine the one-year trajectory of sleep problems, identify clinical correlates, and describe subjective experiences related to persistent sleep problems during recovery from substance use disorders (SUD). This study builds on a sequential mixed method design. The quantitative component features data from a prospective longitudinal study of 127 poly-SUD patients in the Stavanger area in Norway, while the qualitative component describes a thematic analysis of interviews with 16 persons from this study still experiencing sleep problems after at least one year of abstinence. The prevalence of sleep problems at baseline for the whole cohort was 79%. Among the 59 patients who were abstinent after one year, N = 20 (33.9%) had moderate and N = 11 (18.6%) had severe sleep problems. Persistent sleep problems were associated with psychological distress and were experienced as a major challenge in the struggle to stay drug free. Establishing daily routines related to work, school, and care for children were coping strategies for participants with persistent sleep problems. Persistent sleep problems are often overlooked in a clinical setting. Based on our findings, these issues pose a major challenge in the struggle to stay drug free. For patients with psychological distress, and lack of responsibilities that established daily routines, sleep difficulties may result in increased risk of drug use episodes that result in relapse. These results argue that screening and evidence-based methods for insomnia and sleep health-programs should be commonplace adjunct intervention for patients with SUDs.

description: We study the phase diagram of the inverted InAs/GaSb bilayer quantum wells. For small tunneling amplitude between the layers, we find that the system is prone to formation of an s-wave exciton condensate phase, where the spin-structure of the order parameter is uniquely determined by the small spin-orbit coupling arising from the bulk inversion asymmetry. The phase is topologically trivial and does not support edge transport. On the contrary, for large tunneling amplitude, we obtain a topologically non-trivial quantum spin Hall insulator phase with a p-wave exciton order parameter, which enhances the hybridization gap. These topologically distinct insulators are separated by an insulating phase with spontaneously broken time-reversal symmetry. Close to the phase transition between the quantum spin Hall and time-reversal broken phases, the edge transport shows quantized conductance in small samples, whereas in long samples the mean free path associated with the backscattering at the edge is temperature independent, in agreement with recent experiments.

description: Les initiatives entreprises par la communauté de pratique IA Santé (CPIAS) et leur partenaire, l’École de l’Intelligence Artificielle en Santé et le Centre Hospitalier de l’Université de Montréal (EIAS-CHUM), avaient pour but de mobiliser différents intervenants du milieu en favorisant une approche constructive et collaboratrice dans un écosystème dynamique et mouvant. En effet, l’utilisation de l’IA demande des approches transformatrices qui bousculent les pratiques habituelles de gestion technologique, par exemple l’accès aux données nécessaires pour l’entraînement de modèles ou le contrôle et la gestion des performances des algorithmes. Cette publication est un retour en synthèse de l’événement Idéathon qui visait à combler ces besoins et adresser ces problématiques dans un contexte d’innovation hospitalière. Durant l’événement, des équipes ont pu bénéficier de l’intelligence collective des participants et experts présents afin de faire progresser leur idée de projet d’innovation utilisant l’IA.

description: It is argued that the subtle crossover from decoherence-dominated classical magnetism to fluctuation-dominated quantum magnetism is experimentally accessible in graphene nanoribbons. We show that the width of a nanoribbon determines whether the edge magnetism is on the classical side, on the quantum side, or in between. In the classical regime, decoherence is dominant and leads to static spin polarizations at the ribbon edges, which are well described by mean-field theories. The quantum Zeno effect is identified as the basic mechanism which is responsible for the spin polarization and thereby enables the application of graphene in spintronics. On the quantum side, however, the spin polarization is destroyed by dynamical processes. The great tunability of graphene magnetism thus offers a viable route for the study of the quantum-classical crossover.

description: We study the time delay between successive relativistic images in gravitational lensing as a possible discriminator between various collapse end states and hence as a probe of cosmic censorship. Specifically we consider both black hole and naked singularity spacetimes admitting photon spheres where an infinite number of relativistic Einstein Rings can be formed at almost the same radius and naked singularity spacetimes without a photon sphere where multiple relativistic Einstein Rings can form almost up to the center of the lens. The metrics we have considered to sample these scenarios are the Schwarzschild black hole, Janis-Newman-Winicour (naked singularity with photon sphere), Joshi-Malafarina-Narayan, and Tolman-VI (naked singularities without photon sphere) which are a fair sample of the theoretical possibilities. We show that the differential time delay between the relativistic images for naked singularities without a photon sphere progressively decreases for the models we study as opposed to that for black holes and naked singularities with a photon sphere, where it is known to be roughly constant. This characteristic difference in the time delay between successive images for these two cases can be potentially exploited for a source with known intrinsic variability to discriminate between these scenarios even when the images are not spatially resolved.

description: The nonlocality of certain quantum states can be revealed by using local filters before performing a standard Bell test. This phenomenon, known as hidden nonlocality, has been so far demonstrated only for a restricted class of measurements, namely projective measurements. Here we prove the existence of genuine hidden nonlocality. Specifically, we present a class of two-qubit entangled states, for which we construct a local model for the most general local measurements (POVMs), and show that the states violate a Bell inequality after local filtering. Hence there exist entangled states, the nonlocality of which can be revealed only by using a sequence of measurements. Finally, we show that genuine hidden nonlocality can be maximal. There exist entangled states for which a sequence of measurements can lead to maximal violation of a Bell inequality, while the statistics of non-sequential measurements is always local.

description: Offene Problemstellungen nehmen im Mathematikunterricht eine wichtige Rolle ein. Auch im Alltag und in den Wissenschaften (wie den Naturwissenschaften oder der Mathematik) sind häufig nicht alle Informationen vorhanden, die für die Lösung eines Problems nötig wären (Wu, 1994). Ein bestimmter Typ offener Aufgaben sind offene Modellierungsaufgaben, die sich durch ihren Realitätsbezug auszeichnen und anspruchsvolle Übersetzungsprozesse zwischen der Realität und der Mathematik im Sinne des Modellierungskreislaufes erfordern. Die Offenheit wurde in bisherigen Studien zum Modellieren selten untersucht und es fehlt bislang an empirisch untersuchten Förderungsansätzen, die sich gezielt auf die Offenheit als schwierigkeitsgenerierendes Merkmal beziehen. An dieser Stelle setzt das OModA-Projekt (Offene Modellierungsaufgaben in einem selbständigkeitsorientierten Mathematikunterricht) an. Eine zentrale Fragestellung des Projekts ist, welche Effekte Unterricht mit offenen Modellierungsaufgaben im Vergleich zu geschlossenen Modellierungsaufgaben auf Motivation und Leistung beim Modellieren hat. Durchgeführt wird eine Unterrichtsstudie mit experimentellem Design, in der die Wirkungen einer vierstündigen Lernumgebung zu offenen bzw. geschlossenen Aufgaben verglichen wird. Ziele dieses Beitrages sind, die Konzeption der Lernumgebungen vorzustellen und erste Ergebnisse aus der Pilotierungsstudie zu berichten.

description: Background The oncofetal protein insulin-like growth factor II mRNA binding protein 3 (IMP3) is an important factor for cell-migration and adhesion in malignancies. Recent studies have shown a remarkable overexpression of IMP3 in different human malignant neoplasms and also revealed it as an important prognostic marker in some tumor entities. To our knowledge, IMP3 expression has not been investigated in prostate carcinomas so far. Methods Immunohistochemical stainings for IMP3 were performed on tissue microarray (TMA) organized samples from 507 patients: 31 normal prostate tissues, 425 primary carcinomas and 51 prostate cancer metastases or castration-resistant prostate cancers (CRPC). IMP3 immunoreactivity was semiquantitatively scored and correlated with clinical-pathologic parameters including survival. Results IMP3 is significantly stronger expressed in prostate carcinomas compared to normal prostate tissues (p < 0.0001), but did not show significant correlation with the pT-stage, the proliferation index (MIB1), preoperative serum PSA level and the margin status. Only a weak and slightly significant correlation was found with the Gleason score and IMP3 expression failed to show prognostic significance in clinico-pathological correlation-analyses. Conclusions Although IMP3 is overexpressed in a significant proportion of prostate cancer cases, which might be of importance for novel therapeutic approaches, it does not appear to possess any immediate diagnostic or prognostic value, limiting its potential as a tissue biomarker for prostate cancer. These results might be corroborated by the fact, that two independent tumor cohorts were separately reviewed.

description: Das mathematische Modellieren als Prozess des Lösens von Problemen aus der Realität stellt verschiedene Herausforderungen an Schüler*innen, da Kompetenzen im Bereich der reinen Mathematik nicht ausreichen (Greefrath et al., 2013). Es beinhaltet Teilprozesse wie das Strukturieren von Informationen, das Mathematisieren und den Rückbezug des Ergebnisses auf die Realität. Studien zeigen, dass Modellieren durch aktivitätsreiche Lernumgebungen gelernt werden kann (Niss & Blum, 2020). Einen Ansatz zur Förderung von Modellierungskompetenz stellen heuristische Lösungsbeispiele dar (Zöttl et al., 2010; Tropper, 2019). Sie präsentieren ein Problem und eine Schritt-für-Schritt-Lösung, wobei ein Schwerpunkt auf dem strategischen Vorgehen liegt. Das Vorgehen anhand eines Lösungsplans kann als zusätzliche strategische Hilfe gesehen werden. In einer Studie von Schukajlow et al. (2015) berichteten Schüler*innen nach der Arbeit mit dem Lösungsplan, dass sie mehr Planungs-, Wiederholungs-, Elaborations- und Organisationsstrategien einsetzten. Heuristische Lösungsbeispiele zum Modellieren wurden bisher meist textbasiert erprobt. Eine Übertragung des Formats auf Erklärvideos scheint nicht nur vor dem Hintergrund der steigenden Relevanz von Erklärvideos als wichtiger Forschungsgegenstand. Erklärvideos erlauben es, die Anwendung von Strategien im Gegensatz zu Text konkret zu demonstrieren. Gleichzeitig bieten Videos Vorteile wie das Pausieren gegenüber Lehrkraftvorträgen. Um das Potenzial von (textbasierten) heuristischen Lösungsbeispielen und Erklärvideos zu verbinden, wird vorgeschlagen ein solches Video auf Basis folgender Kategorien zu erstellen: Das Problem wird anhand realweltlicher Szenen präsentiert und die Lösung entlang eines Lösungsplans segmentiert. Selbsterklärungsprompts zielen auf die Aktivierung der Lernenden ab. Die Arbeit zu zweit soll dabei die Kommunikation erhöhen. Heuristische Strategien werden im Video deutlich gemacht. Zeichnungen und Schrift erscheinen dynamisch und die Sprache im Video ist möglichst dialogisch (Wirth, im Druck). Da ein großes Interesse auf dem Einfluss eines solchen heuristischen Lösungsbeispielvideos auf den Bearbeitungsprozess von Modellierungsaufgaben liegt, wird in dieser Studie folgende Forschungsfrage untersucht: Welche Veränderungen beim Bearbeitungsprozess einer Modellierungsaufgabe nehmen Schüler*innen nach der Arbeit mit einem heuristischen Lösungsbeispielvideos zum Modellieren wahr?

description: Hysteresis-controlled devices are widely used in industrial applications. For example, cooling devices usually contain a two-point controller, resulting in a nonlinear hybrid system with two discrete states. Dynamic models of systems are essential for optimizing such industrial supply technology. However, conventional system identification approaches can hardly handle hysteresis-controlled devices. Thus, the new identification method Sparse Identification of Nonlinear Dynamics (SINDy) is extended to consider hybrid systems. SINDy composes models from basis functions out of a customized library in a data-driven manner. For modeling systems that behave dependent on their own past as in the case of natural hysteresis, Ferenc Preisach introduced the relay hysteron as an elementary mathematical description. In this new method (SINDyHybrid), tailored basis functions in form of relay hysterons are added to the library which is used by SINDy. Experiments with a hysteresis controlled water basin show that this approach correctly identifies state transitions of hybrid systems and also succeeds in modeling the dynamics of the discrete system states. A novel proximity hysteron achieves the robustness of this method. The impacts of the sampling rate and the signal noise ratio of the measurement data are examined accordingly.

description: We describe the implementation of the renormalized complex MSSM (cMSSM) in the diagram generator FeynArts and the calculational tool FormCalc. This extension allows to perform UV-finite one-loop calculations of cMSSM processes almost fully automatically. The Feynman rules for the cMSSM with counterterms are available as a new model file for FeynArts. Also included are default definitions of the renormalization constants; this fixes the renormalization scheme. Beyond that all model parameters are generic, e.g. we do not impose any relations to restrict the number of input parameters. The model file has been tested extensively for several non-trivial decays and scattering reactions. Our renormalization scheme has been shown to give stable results over large parts of the cMSSM parameter space.

description: Clinical History: A 38-year-old woman presented with painless left neck swelling of progressive growth over a 2-month period. No relevant personal or familiar prior medical history was retrieved. Laboratory evaluation was unremarkable. Clinical evaluation disclosed the presence of a palpable left neck swelling in the submandibular region that was oval in shape and showed an elastic consistency, with preserved mobility to the deep structures of the neck. The lesion was first characterized by ultrasound-guided core biopsy, with a diagnosis of “sarcoma metastasis”. Upon referral to our Hospital, the patient underwent thorough evaluation in a specialized Otorhinolaryngology consultation, which found no additional relevant findings. Repeat fine-needle aspiration (FNA) of the palpable left submandibular lesion was performed, the latter showing features compatible with a malignant fusocelular neoplasm. The patient subsequently underwent left cervical lymphadenectomy. Pathology disclosed a lymph node conglomerate comprised of follicular cell sarcoma; atypical cells were positive for CD21+, CD23+, CD68+. The remaining lymph nodes showed no pathological features.

description: The use of a rod or tube of magnetic material (nickel, iron, Nichrome, Monel metal, stainless steel, etc.) to stabilize an oscillating electric circuit, was first proposed by G. W. Pierce, and such rods were employed by him in the production of standards of frequency in the range from 1,000 cycles per second to about 100,000 cycles and in the measurement of the velocity of sound in solids. Other investigators have used such rods for various purposes, but so far as the writer knows there have been no investigations at great amplitudes of vibration. Quartz crystals, actuated by intense electrostatic fields through the pieze-electric effect, have been employed by Langevin, Boyle, Wood and Loomis, Richards and Loomis, Hubbard, and others to produce within liquids very strong, ultrasonic vibrations, some effects of which they have noted. Intense audible sound, however, has never been produced by use of resonant crystals, because crystals thick enough to give audible sound at resonance would require extremely high voltages to make them oscillate strongly; Wood and Loomis found it necessary to use as much as 50,000 volts between opposite faces of quartz crystals a few millimeters thick to produce intense vibrations of frequencies ten to twenty times that of the highest audible sounds. In the present investigation the object has been to increase the power input of magnetostrictive nickel tubes to the limit as set by the mechanical properties of nickel, and then to discover and investigate properties of the intense audible sound produced by the longitudinal vibration. This research in the sonic range has followed somewhat the work done by the above mentioned experimenters in the supersonic range, but has produced some results and effects that so far have never been reported

description: Over time, several definitions of stress have been put forward. It was first thought to be the result of external pressure, and later it was linked to internal tension. These days, the most widely recognized definition is the one that discusses an individual's interactions with their surroundings. When a person lacks the resources to meet the expectations and stress of their environment, they suffer from psychological and physical strain. As such, stress is more common in particular circumstances and among some people than in others. An individual's or an organization's capacity to achieve its objectives may be hampered by stress.Our theoretical theories were assessed using information obtained by means of aquestionnaire survey that was distributed. Before the formal poll, a pilot study was conducted. Then revised the questionnaire in light of the trial investigation's conclusions.The questionnaire was sent at random among the large number of employed individuals who work for various organizations located in Visakhapatnam City, Andhra Pradesh. Consequently, 174 people were selected to be considered as the study sample. This study aims to explore the psychological factors that affect stress at working environment of different individuals.

description: Schon vor der Corona-Pandemie verwendeten in Deutschland fast die Hälfte aller YouTube-Nutzer*innen im Alter zwischen 12-19 Jahren die Plattform auch zum außerschulischen Lernen (Jebe et al., 2019). Der Fernunterricht der letzten zwei Jahre und die Umsetzungen des Digitalisierungspakts, wie Tablet-Ausstattungen von Klassen und ganzen Schulen, haben die Grenzen zwischen schulischem und außerschulischem Lernen verwischt. Bezogen auf Bildungsinhalte öffnet YouTube – im Gegensatz zum überwiegend staatlich kontrollierten, formalen Bildungssystem bzw. zu professionellen Medienproduktionsstandards – einer breiteren Gruppe von Produzierenden, darunter auch nicht fachkundigen Personen, einen überwiegend unregulierten Zugang zu einem (potenziellen) Massenmedium (Honkomp-Wilkens, 2022, S. 497). Was bedeutet der zunehmende häusliche Gebrauch von Erklärvideos für den Unterricht der schulischen Lehrkraft? Wie verhalten sich die Lerngewohnheiten, die sich unreflektiert bei mehrfacher und wörtlicher Wiederholung des gleichen Sachverhalts herausbilden, zu den fachlichen und allgemeinen Bildungsansprüchen, die der Unterrichtsplanung der Lehrkraft zugrunde liegen?
Neue Wege im Mathematikunterricht – Auf den Spuren Mathilde Vaertings

description: In der Zeit der Reformpädagogik kamen viele Ansätze auf, (Mathematik-) Unterricht zu verändern und zu verbessern. Prominente Pädagog*innen aus dieser Zeit, wie beispielsweise Gaudig, Kerschensteiner oder Montessori, sind auch heute noch bekannt. Mathilde Vaerting (1884–1977) hingegen wird mit den reformpädagogischen Ideen der damaligen Zeit eher nicht in Zusammenhang gebracht, sondern, wenn überhaupt, aus der Gender-Perspektive in den Fokus genommen (Kraul, 1999; Naumann, 2001). Dabei sind ihre Ideen zur Verbesserung des Mathematikunterrichts nicht nur aus damaliger Sicht revolutionär, sondern auch aus heutiger Perspektive höchst interessant. Zudem ist Vaerting eine bemerkenswerte Persönlichkeit: Zum einen ist sie Deutschlands erste Professorin für Erziehungswissenschaften auf einem Lehrstuhl, der eigens für die akademische Ausbildung von Volksschullehrer*innen an der Universität Jena eingerichtet wurde. Zum anderen beruht ihr Werk „Neue Wege im mathematischen Unterricht“ (1921) auf ihren Erfahrungen als Lehrerin an Mädchenschulen. Und das zu einer Zeit, in der – von zumeist männlichen Protagonisten – darüber diskutiert wurde, ob Frauen überhaupt eine mathematische Begabung vorzuweisen hätten, obwohl es Mathematik erst ab 1908 in den Lehrplänen der Mädchen gab. Da sich vor dem Hintergrund der „alten Wege“ im Mathematikunterricht das innovative Moment von Vaertings „neuen Wegen“ besser verstehen und einordnen lässt, folgt zunächst ein Blick in die Rahmenbedingungen der Mädchenbildung der damaligen Zeit.

Entanglement spectra between coupled Tomonaga-Luttinger liquids: Applications to ladder systems and topological phases

description: We study the entanglement spectrum (ES) and entropy between two coupled Tomonaga-Luttinger liquids (TLLs) on parallel periodic chains. This problem gives access to the entanglement properties of various interesting systems, such as spin ladders as well as two-dimensional topological phases. By expanding interchain interactions to quadratic order in bosonic fields, we are able to calculate the ES for both gapped and gapless systems using only methods for free theories. In certain gapless phases of coupled non-chiral TLLs, we interestingly find an ES with a dispersion relation proportional to the square root of the subsystem momentum, which we relate to a long-range interaction in the entanglement Hamiltonian. We numerically demonstrate the emergence of this unusual dispersion in a model of hard-core bosons on a ladder. In gapped phases of coupled non-chiral TLLs, which are relevant to spin ladders and topological insulators, we show that the ES consists of linearly dispersing modes, which resembles the spectrum of a single-chain TLL but is characterized by a modified TLL parameter. Based on a calculation for coupled chiral TLLs, we are also able to provide a very simple proof for the correspondence between the ES and the edge-state spectrum in quantum Hall systems consistent with previous numerical and analytical studies.
