description: In the present work, we revisit the process of gravitational collapse of a spherically symmetric homogeneous dust fluid which is known as the Oppenheimer-Snyder (OS) model [1]. We show that such a scenario would not end in a spacetime singularity when the spin degrees of freedom of fermionic particles within the collapsing cloud are taken into account. To this purpose, we take the matter content of the stellar object as a homogeneous Weyssenhoff fluid which is a generalization of perfect fluid in general relativity (GR) to include the spin of matter. Employing the homogeneous and isotropic FLRW metric for the interior spacetime setup, it is shown that the spin of matter, in the context of a negative pressure, acts against the pull of gravity and decelerates the dynamical evolution of the collapse in its later stages. Our results bode a picture of gravitational collapse in which the collapse process halts at a finite radius whose value depends on the initial configuration. We thus show that the spacetime singularity that occurs in the OS model is replaced by a non-singular bounce beyond which the collapsing cloud re-expands to infinity. Depending on the model parameters, one can find a minimum value for the boundary of the collapsing cloud or correspondingly a threshold value for the mass content below which the horizon formation can be avoided. Our results are supported by a thorough numerical analysis.

description: Answering a question by Angel, Holroyd, Martin, Wilson and Winkler, we show that the maximal number of non-colliding coupled simple random walks on the complete graph $K_N$, which take turns, moving one at a time, is monotone in $N$. We use this fact to couple $\lceil \frac N4 \rceil$ such walks on $K_N$, improving the previous $Ω(N/\log N)$ lower bound of Angel et al. We also introduce a new generalization of simple avoidance coupling which we call partially ordered simple avoidance coupling and provide a monotonicity result for this extension as well.

description: Xclaim (x-ray core level atomic multiplets) is a graphical interface for the calculation of core-hole spectroscopy and ground state properties within a charge-transfer multiplet model taking into account a many-body hamiltonian with Coulomb, spin-orbit, crystal-field, and hybridization interactions. Using Hartree-Fock estimates for the Coulomb and spin-orbit interactions and ligand field parameters (crystal-field, hybridization and charge-transfer energy) the program can calculate x-ray absorption spectroscopy (XAS), x-ray photoemission spectroscopy (XPS), photoemission spectrospcy (PES) and inverse photoemission (IPES) for d- and f-valence metals and different absorption edges. The program runs in Linux, Windows and MacOS platforms.
Four dimensional superconformal theories from M5 branes

description: We study N=1 superconformal theories in four dimensions obtained wrapping M5 branes on a Riemann surface. We propose a method to determine from the spectral curve the scaling dimension of chiral operators in the SCFT. Whenever the R-symmetry has to be determined via a-maximization, our procedure allows us to determine the charge of chiral operators under the "trial" R-symmetry. Our proposal reduces to the correct prescription in the special case of N=2 theories of class S. We perform several consistency checks and apply our method to study some new SCFT's such as N=1 deformations of Argyres-Douglas theories.

description: The spectrum of a one-dimensional pseudospin-one Hamiltonian with a three-component potential is studied for two configurations: (i) all the potential components are constants over the whole coordinate space and (ii) the profile of some components is of a rectangular form. In case (i), it is illustrated how the structure of three (lower, middle and upper) bands depends on the configuration of potential strengths including the appearance of flat bands at some special values of these strengths. In case (ii), the set of two equations for finding bound states is derived. The spectrum of bound-state energies is shown to depend crucially on the configuration of potential strengths. Each of these configurations is specified by a single strength parameter $V$. The bound-state energies are calculated as functions of the strength $V$ and a one-point approach is developed realizing correspondent point interactions. For different potential configurations, the energy dependence on the strength $V$ is described in detail, including its one-point approximation. From a whole variety of bound-state spectra, four characteristic types are singled out.

description: We study magnetism in simple models for rare earth quasicrystals by means of a two-step theoretical approach. First, we compute RKKY interactions from a tight-binding Hamiltonian defined on a two-dimensional quasiperiodic tiling. Second, we examine the statistical mechanics of Ising spins coupled via these interactions using Monte Carlo simulations. We find the emergence of strongly coupled spin clusters with significantly weaker inter-cluster coupling, and a transition to a low-temperature phase that has long-range order evidenced by a finite domain wall tension.

description: We analyze the functional integral for quantum Conformal Gravity and show that with the help of a Hubbard-Stratonovich transformation, the action can be broken into a local quadratic-curvature theory coupled to a scalar field. A one-loop effective action calculation reveals that strong fluctuations of the metric field are capable of spontaneously generating a dimensionally transmuted parameter which in the weak-field sector of the broken phase induces a Starobinsky-type f(R)-model with a gravi-cosmological constant. A resulting non-trivial relation between Starobinsky'sparameter and the cosmological constant is highlighted and implications for cosmic inflation are briefly discussed and compared with recent PLANCK and BICEP2 data.

description: We discuss the dispersion relations of Nambu-Goldstone (NG) modes associated with spontaneous breaking of internal symmetries at finite temperature and/or density. We show that the dispersion relations of type-A (I) and type-B (II) NG modes are linear and quadratic in momentum, whose imaginary parts are quadratic and quartic, respectively. In both cases, the real parts of the dispersion relations are larger than the imaginary parts when the momentum is small, so that the NG modes can propagate far away. We derive the gap formula for NG modes in the presence of a small explicit breaking term. We also discuss the gapped partners of type-B NG modes, when type-A and type-B NG modes coexist.

description: The lowest order radiative corrections to the cross section and asymmetries measured in experiments on semi-inclusive deep inelastic scattering of polarized particles were calculated. Both exact and leading log expressions were presented and discussed for the total correction that include the contributions from the processes of (i) real photon emission with semi-inclusive processes, (ii) loop diagrams, and (iii) real photon emission with exclusive processes. Radiative corrections to the Sivers and Collins asymmetries in $π^+$ electroproduction were studied numerically within the kinematical conditions of modern experimental environments at Jefferson Laboratory (JLab). The Wandzura-Wilczek approximation for the semi-inclusive structure functions and MAID2007 parameterization for the six amplitudes of exclusive processes were used in numeric analyses. The results show that (i) radiative effects can generate a correction comparable to the size of Sivers and Collins asymmetries at the Born level, (ii) there is good agreement between the exact and leading-order corrections, (iii) external functions (that is, other than the Sivers and Collins functions in the respective asymmetries) can generate a contribution to the radiative correction up to 20\%, and (iv) there exists a strong dependence of the radiative correction on the models for semi-inclusive and exclusive structure functions.

description: We investigate the quantum transport properties of multichannel nanoribbons made of materials described by the Dirac equation, under an in-plane magnetic field. In the low energy regime, positive and negative finger-gate potentials allow the electrons to make intra-subband transitions via hole-like or electron-like quasibound states (QBS), respectively, resulting in dips in the conductance. In the high energy regime, double dip structures in the conductance are found, attributed to spin-flip or spin-nonflip inter-subband transitions through the QBSs. Inverting the finger-gate polarity offers the possibility to manipulate the spin polarized electronic transport to achieve a controlled spin-switch.

Year: 2022

description: Die vorliegende Arbeit hatte zum Ziel, die Auswirkungen der Body Positivity-Bewegung, sowie des Trends Instagram vs. Reality auf Instagram auf die Rezipienten und ihr Selbstwertgefühl und ihre Selbst-Objektifizierung zu erforschen. (Vgl. Ivanova, 2020: 4) Da das Thema zu Body Appreciation Captions noch nicht weit erforscht ist, war die Wirkung von körperpositiven Bildunterschriften auf die weiblichen Rezipienten für die vorliegende Arbeit von großem Interesse. Zu diesem Zweck wurden Frauen im Alter von 18 bis 30 Jahre in einem Online-Experiment, in sechs Gruppen (Design 3x2) befragt, um einen Einblick in bisher noch nicht untersuchten Aspekt von Body Positivity zu bekommen. (Vgl. Ivanova, 2020: 4) Die Ergebnisse wurden statistisch mittels SPSS analysiert, um die Forschungsfragen zu beantworten und die Hypothesen zu überprüfen. In Anbetracht der Ergebnisse zeigte sich ein signifikanter Einfluss von den Body Appreciation Captions auf das Selbstwertgefühl der Probandinnen. Der Konsum von Instagram vs. Reality-Bildern führt zu einem steigenden Selbstwertgefühl im Vergleich zu realitätsnahen oder idealen Körperbildern. Es zeigte sich jedoch keinen signifikanten Einfluss weder von idealisierten Bildern noch von den Body Appreciation Captions auf den Grad der Selbst-Objektifizierung der Probandinnen. Dennoch können die Erkenntnisse dieser Arbeit als Grundlage für weitere Forschungen dienen.
description: This thesis aimed to explore the impact of the Body Positivity movement, as well as the Instagram vs. Reality trend on Instagram, on recipients and their self-esteem and self-objectification. Since the topic on body appreciation captions has not been widely researched, the effect of body positive captions on female recipients was of great interest for the present work. For this purpose, women aged 18 to 30 were interviewed in an online experiment, in six groups (design 3x2), in order to gain insight into previously unexamined aspects of body positivity. The results the groups were statistically analyzed using SPSS to answer the research questions & test the hypotheses. Considering the results, there was a significant influence of the Body Appreciation Captions on the subjects' self-esteem. Consumption of Instagram vs. reality images leads to an increase in self-esteem compared to reality or ideal body images. However, neither idealized images nor body appreciation captions were shown to have a significant impact on the subjects' level of self-objectification. Nevertheless, the findings of this work can serve as a primer for further research.

description: T11 Target structure (T11TS), a membrane glycoprotein isolated from sheep erythrocytes, reverses the immune suppressed state of brain tumor induced animals by boosting the functional status of the immune cells. This study aims at aiding in the design of more efficacious brain tumor therapies with T11 target structure. We propose a mathematical model for brain tumor (glioma) and the immune system interactions, which aims in designing efficacious brain tumor therapy. The model encompasses considerations of the interactive dynamics of macrophages, cytotoxic T lymphocytes, glioma cells, TGF-$β$, IFN-$γ$ and the T11TS. The system undergoes sensitivity analysis, that determines which state variables are sensitive to the given parameters and the parameters are estimated from the published data. Computer simulations were used for model verification and validation, which highlight the importance of T11 target structure in brain tumor therapy.

description: Diese Masterarbeit beleuchtet die Lösungsansätze für die Klimakrise im Feld der Global Climate Governance im Kontext der 26. UN-Klimakonferenz (COP26). Damit einhergehend wird betrachtet, welche Krisenbearbeitungsstrategien verfolgt werden, welche Rolle Machtstrukturen spielen und welche umkämpften Interessen sich gegenüberstehen. Im Zuge dessen ist auch die Frage nach dem Verständnis der Klimakrise bedeutend. Die Begrifflichkeiten Green Economy und Klimagerechtigkeit werden in der vorliegenden Arbeit als sich idealtypisch gegenüberstehend identifiziert. Ziel der Arbeit ist es, Barrieren für die Umsetzung von Klimagerechtigkeit im Kontext der COP26 herauszustellen. Hierfür wurde eine Analyse der Perspektiven der Klimaaktivist*innen anhand von qualitativen Interviews durchgeführt. Durch die Analyse kristallisiert sich heraus, dass Barrieren finanzieller, institutioneller und diskursiver Art für die Umsetzung von Klimagerechtigkeit im Kontext der COP26 bestehen, die sich durch Machtstrukturen manifestieren. Anhand der Beschäftigung mit dem Feld der Global Climate Governance wird sichtbar, dass emanzipatorisch-progressive Lösungsansätze in Richtung Degrowth vermehrt diskutiert werden sollten, um bestehende Barrieren für die Umsetzung von Klimagerechtigkeit aufzubrechen.

description: An analysis of the failure statistics of a commercially available fault-tolerant system shows that administration and software are the major contributors to failure. Various approaches to software fault tolerance are then discussed notably process-pairs, transactions and reliable storage. It is pointed out that faults in production software are often soft (transient) and that a transaction mechanism combined with persistent process-pairs provides fault-tolerant execution – the key to software fault-tolerance.

description: Manufacturing methods are divided into two groups as traditional and non-traditional manucaturing methods. Cutters are being used in traditional manufacturing method and since the relative movement between base metal and cutter is either linear or circular, the machined product’s surface is generally either linear or circular. Also it is known that traditional manufacturing methods are limited for quite big or small parts therefore non-traditional manufacturing methods were required. One of the non-traditional Method in another word “Modern Method” is Water Jet Cutting’s usage was being started in 1970’s. Abbresive Water Jet Cutting which has abbresive particules in water jet was being used in 1980’s. It is considered that the handling of desired surface quality after cutting with Water Jet Cutting Process which has a wide usage area in technology depends on material type, pressure, cutting velocity and water jet diameter. Because of that reason some experiments and analysis study accomplished
 with two different type of materials, changing pressure, cutting velocity and water jet diameter.

description: In this paper, we present a new approach for Covid-19 Pandemic spreading simulation based on fuzzy multi agents. The agent parameters consider distribution of the population according to age, and the index of socio-economic fragility. Medical knowledge affirms that the COVID-19 main risk factors are age and obesity. The worst medical situation is caused by the combination of these two risk factors which in almost99% of cases finish in ICU. The appearance of virus variants is another aspect parameter by our simulation through a simplified modeling of the contagiousness. Using real data from people from West Indies (Guadeloupe, F.W.I.), we modeled the infection rate of the risk population, if neither vaccination nor barrier gestures are respected. The results show that hospital capacities are exceeded, and the number of deaths exceeds 2% of the infected population, which is close to the reality.
title: Ideologie im Denkhorizont Foucaults
Creators: name: Farr, Christian
Year: 2022

description: Innerhalb der Ideologieforschung klafft eine offene Stelle, ein Riss, der sich mit den Konzepten und Methoden Foucaults schließen lässt. Die Literatur spricht seit Anbeginn der Tradition der Ideologiekritik vehement von den Fehllelsitungen eines verkehrten Bewusstseins, welches, vom Trugbild umgarnt, lediglich zur wahren Erkenntnis über die Beschaffenheit der Dinge und Prozesse geführt werden müsse. Namentlich in der marxistrischen Tradition: die Erkenntnis, dass nicht der (geisitge) Überbau, sondern die (ökonomische) Basis die gesellschaftlichen Verhältnisse determiniert. Dieser Ansatz selbst hat jedoch derart viele Widersprüche, dass dieses Abstract nicht ausreicht jene zusammenzufassen. Die Thesis wiederum widmet sich der Aufgabe, diesen Widersprüchen auf die Spur zu gehen und zum Bewusstsein, als eine Angriffsfläche der Ideologie, noch den Körper zu stellen und damit aufzuzeigen, dass es damit nicht getan ist, lediglich seine Denkweise zu ändern, denn die Fabriken der Wahrhheitsproduktion schleusen ihre Waren tief in die Zellen des Körpers ein, sodass neben der Theorie ebenfalls die Lebensraxis unter die Lupe einer Ideologieforschung genommen werden muss. Den Untersuchungen der Auswirkungen von Machtverhältnissen auf die Subjektivität und ins Besondere deren Einschreibung in den Körper, hat Michel Foucault einen bedeutenden Anteil seiner Forschungszeit gewidmet, daher die Integration seines Gedankensguts in das Forschungsgebiet. Am Ende der Thesis wird ein kreativer Denkansatz zum Besten gegeben. Dieser kann als Methodik zur Abwehr invasiver ideologischer Strahlungen betrachtet werden und als Praxis zur Generierung eigenst gewünschter Subjektivitäten und Ideologien dienen. Denn: Wir können niemals ohne Ideologien sein, doch wir können unsere Haltung zu solchen bestimmen und weg von starren-satistischen Mustern, hin zu wandelbaren, plastischen (Denk-)Formationen gehen.

description: Interpolating functional method is a powerful tool for studying the behavior of a quantity in the intermediate region of the parameter space of interest by using its perturbative expansions at both ends. Recently several interpolating functional methods have been proposed, in addition to the well-known Pade approximant, namely the "Fractional Power of Polynomial" (FPP) and the "Fractional Power of Rational functions" (FPR) methods. Since combinations of these methods also give interpolating functions, we may end up with multitudes of the possible approaches. So a criterion for choosing an appropriate interpolating function is very much needed. In this paper, we propose reference quantities which can be used for choosing a good interpolating function. In order to validate the prescription based on these quantities, we study the degree of correlation between "the reference quantities" and the "actual degree of deviation between the interpolating function and the true function" in examples where the true functions are known.

title: Geschichtsvermittlung im Museum als Zugang zu kulturreflexivem Lernen bei DaZ-Lernenden am Beispiel des Museums Haus der Geschichte Österreich
Creators: name: Horak, Lisa
Year: 2022

description: Kulturellem Lernen im DaZ-Unterricht kommt eine wesentliche Rolle zu, da sich DaZ-Lernende aufgrund ihrer Klassifikation als ‚mit Migrationshintergrund‘ in einem gesellschaftlichen Spannungsfeld politischer, symbolischer und kultureller Machtverhältnisse wiederfinden. Kulturreflexives Lernen wird hierbei als Ansatz verstanden, der genau diese Rahmenbedingungen sowie die Eröffnung von Handlungsräumen in ihnen als Ziel innerhalb des DaZ-Unterrichts formuliert. Derzeit fehlt es jedoch an Erforschungen konkreter Umsetzungen dieses Ansatzes im DaZ-Kontext, woran diese Arbeit anknüpft. Ausgangspunkt war dabei die Konzeption von Workshops für DaZ-Sprechende des Museums Haus der Geschichte Österreich (HdGÖ). Diese wurden durch das Vermittlungsteam des Museums in Kooperation mit DaZ-Expert*innen des WUKs erstellt und im Zuge dieser Arbeit wissenschaftlich begleitet. Die Schnittstelle dieser Felder wurde dabei als ein Zugang gesehen, mit dem kulturreflexives Lernen durch Geschichtsvermittlung zielführend in den DaZ-Unterricht integriert werden kann. Die übergeordnete Forschungfrage war, welche Auswirkungen die Teilnahme an historischen Work-Shops im HdGÖ auf DaZ-Lernende in Hinblick auf Zielsetzungen des kulturreflexiven Lernens hat. Dafür wurden zehn semistrukturierte Leitfadeninterviews mit Teilnehmer*innen der Work-Shops geführt und durch eine Qualitative Inhaltsanalyse ausgewertet. Die Ergebnisse zeigten, dass die Teilnahme an den Work-Shops reflexive Lernprozesse einleiten, Machtkritik fördern und gesellschaftliche Handlungsspielräume sichtbar machen können. Zusätzlich wurden Implikationen zur Integration historischer Inhalte im DaZ-Unterricht erkenntlich und der Mehrwert des Museums als Ort des kulturellen Lernens im DaZ-Kontext konnte aufgezeigt werden. Die Relevanz der Erkenntnisse beläuft sich daher auf beide Felder, den DaZ-Bereich sowie die Geschichtsvermittlung im Museum, sowohl in Bezug auf kulturelle Teilhabe als auch hinsichtlich des kulturellen Lernen im Zweitsprachenunterricht.

description: We study the classification of interacting fermionic and bosonic symmetry protected topological (SPT) states. We define a SPT state as whether or not it is separated from the trivial state through a bulk phase transition, which is a general definition applicable to SPT states with or without spatial symmetries. We show that in all dimensions short range interactions can reduce the classification of free fermion SPT states, and we demonstrate these results by making connection between fermionic and bosonic SPT states. We first demonstrate that our formalism gives the correct classification for all the known SPT states, with or without interaction, then we will generalize our method to SPT states that involve the spatial inversion symmetry.

description: A detailed understanding of how anthropogenic activities affect ecosystems and the services they provide is essential for sustainable management. However, assessments of the impact of multiple drivers on complex ecosystems is often challenged by lack of data at the relevant spatio-temporal resolution or knowledge of interactions among drivers. The SW Greenland coast and shelf is important for the industrial and sustenance fishing that is essential for Greenland. Here, we aim to describe decadal changes of the ecosystem and identify key drivers. To describe ecosystem dynamics we analysed changes in the 33 species of demersal fish found in 5713 bottom trawls collected on the shelf from 1993 to 2016. We find substantial
 increase in average biomass combined with increases in average individual weight, average trophic level and composition of dominant species. Using previous studies as a baseline we interpret the observed changes as a partial recovery of an over-exploited system. Sea ice cover, run-off from the Greenland Ice Sheet, seafloor trawling and water mass distribution are all known drivers of ecosystem change in the study area. Although, the impact of each driver varies over the last 2-3 decades all appear to facilitate increase in fish biomass. Climate change-related melting of sea ice and the Greenland Ice Sheet likely sustained increased primary production by increasing light and nutrient availability. Increases in temperature and salinity indicates increased inflow of Atlantic water, which increase connectivity to lower latitude systems. Finally, decreased trawling effort combined with mitigation measures to decrease by-catch may have decreased fish mortality. This suggest that a combination climate change and long-term hydrographic variability may have facilitated the recovery of fish stocks. Finally, the massive changes observed in fish biomass, size and trophic level of the fish community is likely to be a strong driver for cascading effects to other components of the SW Greenland shelf ecosystem.

description: To exactly answer which density region that some frequently used symmetry-energy-sensitive observables probe, for the first time, we make a study of decomposition of the sensitivity of some symmetry-energy-sensitive observables. It is found that for the Au+Au reaction at incident beam energies of 200 and 400 MeV/nucleon, frequently used symmetry-energy-sensitive observables mainly probe the density-dependent symmetry energy around 1.25$ρ_{0}$ (for pionic observables) or 1.5$ρ_{0}$ (for nucleonic observables). Effects of the symmetry energy in the low-density region is in general small but observable. The fact that the symmetry-energy-sensitive observables are not sensitive to the symmetry energy in the maximal baryon-density region increases the difficulty of studying nuclear symmetry energy at super-density.

description: We find the hydrodynamic equations of a system of particles constrained to be in the lowest Landau level. We interpret the hydrodynamic theory as a Hamiltonian system with the Poisson brackets between the hydrodynamic variables determined from the noncommutativity of space. We argue that the most general hydrodynamic theory can be obtained from this Hamiltonian system by allowing the Righi-Leduc coefficient to be an arbitrary function of thermodynamic variables. We compute the Righi-Leduc coefficients at high temperatures and show that it satisfies the requirements of particle-hole symmetry, which we outline.

title: Gendereinflüsse auf die Schulleistung in der Schuleingangsphase
Creators: name: Massoumzadeh, Miriam
Year: 2022

description: Zahlreiche schulleistungsbezogene Untersuchungen wie PISA, IGLU, TIMSS usw. beschäftigen sich nicht nur mit den Schulfähigkeiten an und für sich, sondern auch mit Geschlechterunterschieden und möglichen Gendereinflüssen auf die Schulleistungen. Es gibt einerseits Hinweise darauf, dass Geschlechterunterschiede bereits vor Schuleinstieg vorhanden sind (Gibbs, 2010; Wie et al., 2015; Oppermann et al., 2020), andere hingegen, die erst gegen Ende der Primarstufe Unterschiede finden und eine Vergrößerung der Unterschiede mit steigendem Alter vermuten (Wei et al, 2015). Die vorliegende Studie untersuchte 344 Kinder (190 weiblich, 54.9%) der zweiten Schulstufe und analysierte sie hinsichtlich Geschlechterunterschieden in der gezeigten Leistung in unterschiedlichen Bereichen. Beim Lesen, Addieren und Subtrahieren sowie bei der Informationsverarbeitungsgeschwindigkeit wurden keine Unterschiede zwischen den Geschlechtern gefunden. Im Schreiben schnitten die Mädchen bezüglich orthographischer Schreibung (p = .014) und der lauttreuen Schreibung (p = .016) besser ab als die Buben. Im Untertest mit komplexeren numerische Operationen erzielten die Buben die besseren Ergebnisse (p = .018). Insgesamt konnten weniger Geschlechterunterschiede gefunden werden, als es vorangegangene Literatur vermuten ließ, was den Trend in Richtung einer Verringerung der Geschlechterunterschiede (Hußmann et al., 2017) untermauert.
description: Numerous school performance-related studies such as PISA, IGLU, TIMSS, etc. are not only concerned with school abilities, but also with gender differences and gender influences on school performance. There is evidence that gender differences are already shown before school entry (Gibbs, 2010; Tranalan Wie et al 2015; Oppermann et al, 2020), others that find differences only later in primary school and suggest a widening of differences with increasing age (Wei et al, 2015). The present study examined 344 children (190 female, 54.9%) visiting second grade. Data was analyzed regarding gender differences in children‘s performance in specific domains. No gender differences were found in reading, addition, subtraction, and information processing. Girls performed better than boys in terms of orthographic spelling (p = .014) and phonetic spelling (p = .016). In the subtest complex numerical operations, the boys scored better (p = .018) than the girls. Overall, fewer gender differences were found than previous literature suggested. This may be another hint on decreasing gender differences (Hußmann et al., 2017).
SOME ASPECTS OF INCREASING THE INNOVATION ACTIVITY OF SMALL BUSINESSES

Subjects: innovation, small business

description: Small business significantly affects the transformation of the structure of the economy, becoming a special sector for the formation of new markets. According to available estimates, small firms will need much less time than large companies to research the bulk of economic innovations and bring them to the form of an industrial design. A prerequisite for the development of innovative small business is a developed support infrastructure, the existence of an effective system of intellectual property protection, the formation of flexible market mechanisms to increase the business activity of entrepreneurs, primarily due to the continuous process of improving their skills and constant self-education. Only entrepreneurship based on a "knowledge economy", i.e. entrepreneurship, applying and using new knowledge in its activities and constantly increasing and replenishing them, can be called innovative and can help create the prerequisites for the formation of the National Innovation System. To develop and introduce product and process innovations that determine the innovativeness of entrepreneurial activity, a process of self-education and the exchange of knowledge and experience are required. The following factors can be identified as factors determining the important role of small businesses in the field of innovation.

description: This paper provides a review of the literature on ride-hailing applications (RHA) in Southeast Asia (SEA) to enhance the understanding of RHA’s impacts on the urban transportation sector and to inform related planning and regulatory efforts in the context of developing countries. The conceptual framework is based on the stakeholder approach, which identifies three groups of stakeholders: the demand-side, the supply-side, and the public-sector stakeholders. A search on scholarly databases yielded 49 related articles. The results of the review illustrate certain similarities between RHA services in SEA with those reported from developed countries, such as the socio-economic profile of the users. However, several observations unique to the SEA context were also revealed, including (1) the dominance of motorcycles; (2) commuting as the main RHA trip purpose; (3) a higher frequency of RHA use; and (4) a significant proportion of full-time RHA drivers. The review also highlighted research gaps in the literature of RHA in SEA, particularly on how RHA can influence travelers’ behavior, its effects on the incumbent transport operators, and its environmental impacts.
Custom v. Standardized Risk Models

description: We discuss when and why custom multi-factor risk models are warranted and give source code for computing some risk factors. Pension/mutual funds do not require customization but standardization. However, using standardized risk models in quant trading with much shorter holding horizons is suboptimal: 1) longer horizon risk factors (value, growth, etc.) increase noise trades and trading costs; 2) arbitrary risk factors can neutralize alpha; 3) "standardized" industries are artificial and insufficiently granular; 4) normalization of style risk factors is lost for the trading universe; 5) diversifying risk models lowers P&L correlations, reduces turnover and market impact, and increases capacity. We discuss various aspects of custom risk model building.

Incremental Compilation Support in Clang

Publisher: name: Zenodo

description: Cling is a C++ interpreter built on top of clang and llvm. In a nutshell, it uses clang's incremental compilation facilities to process code chunk-by-chunk by assuming an ever-growing translation unit. Code is then lowered into llvm IR and run by the llvm jit. Cling has implemented language "extensions" such as execution statements on the global scope and error recovery. Cling is in the core of high-energy physics research -- it is heavily used during data analysis of exabytes of particle physics data coming from the Large Hadron Collider (LHC) and other particle physics experiments. We recently started a project aim at improving cling's sustainability and to make it a standalone tool. In this poster we would like to present one of the project's main directions -- move parts of cling upstream along with the clang and llvm features that enable them. Over the years we have slowly moved some patches upstream. However we still have around 100 patches in the clang fork. Most of them are in the context of extending the incremental compilation support for clang. The incremental compilation poses some challenges in the clang infrastructure. For example, we need to tune CodeGen to work with multiple llvm::Module instances, and finalize per each end-of-translation unit (we have multiple of them). Other changes include small adjustments in the FileManager's caching mechanism, and bug fixes in the SourceManager (code which can be reached mostly from within our setup). One conclusion we can draw from our research is that the clang infrastructure fits amazingly well to something which was not its main use case. The grand total of our diffs against clang-9 is: `62 files changed, 1294 insertions(+), 231 deletions(-)`. Cling is currently being upgraded from llvm-5 to llvm-9. A major weakness of cling's infrastructure is that it does not work with the clang Action infrastructure due to the lack of an IncrementalAction. We will present a possible way forward would be to implement a clang::IncrementalAction as a starting point.

description: Agricultural production is highly dependent on naturally occurring environmental conditions like change of seasons and the weather. Especially in fruit and wine growing, late frosts occurring shortly after the crops have sprouted have the potential to cause massive damage to plants [L1,L2] [1]. In this article we present a cost-efficient temperature monitoring system for detecting and reacting to late frosts to prevent crop failures. The proposed solution includes a data space where Internet of Things (IoT) devices can form a cyber-physical system (CPS) to interact with their nearby environment and securely exchange data. Based on this data, more accurate predictions can be made in the future using machine learning (ML), which will further contribute to minimising economic damage caused by crop failures.
