description: KI-basierte Tools wie ChatGPT bzw. GPT-4 verändern derzeit die Hochschullandschaft und vielerorts wird bereits über die Konsequenzen für die zukünftigen Lehr- und Prüfungsformen diskutiert. Um hier eine empirische Grundlage zu schaffen, ist eine deutschlandweite Befragung von Studierenden durchgeführt worden, in welcher das Nutzungsverhalten im Umgang mit KI-basierten Tools im Rahmen des Studiums und Alltags erfasst wurde. Hierbei wurden unter anderem diverse Funktionen der KIbasierten Tools identifiziert, die für die Studierenden als besonders wichtig eingeschätzt wurden. Das Ziel der quantitativen Befragung lag somit in der Erfassung davon, wie KI-Tools genutzt werden und welche Faktoren für die Nutzung maßgeblich sind. Insgesamt haben sich deutschlandweit über 6300 Studierende an der anonymen Befragung beteiligt. Die Ergebnisse dieser quantitativen Analyse verdeutlichen, dass fast zwei Drittel der befragten Studierenden KI-basierte Tools im Rahmen des Studiums nutzen bzw. genutzt haben. Explizit nennen in diesem Kontext fast die Hälfte der befragten Studierenden ChatGPT bzw. GPT-4 als genutztes Tool. Am häufigsten nutzen Studierende der Ingenieurwissenschaften sowie Mathematik und Naturwissenschaften KI-basierte Tools. Eine differenzierte Betrachtung des Nutzungsverhaltens verdeutlicht, dass die Studierenden KI-basierte Tools vielfältig einsetzen. Die Klärung von Verständnisfragen und Erläuterung fachspezifischer Konzepte zählen in diesem Kontext zu den relevantesten Nutzungsgründen.

description: Thyroid cancer (TC) is poised to become the fourth most prevalent global malignancy, highlighting the urgency for innovative therapeutic strategies. Current treatments often come with significant adverse effects, emphasizing the necessity for targeted drugs with reduced side effects. In this study, we have employed a comprehensive approach, including network pharmacology, molecular docking, molecular dynamics simulations, and MMPBSA to uncover the potential compounds within Eclipta prostrata and their interactions with SRC kinase of TC. The Src family of kinases is a versatile family of nonreceptor tyrosine kinase, regulating key cellular processes responsible for mediating thyroid tumor progression. Our aim is to harness nature’s arsenal for the development of safe and effective TC therapeutics. We have identifyied six E. prostrata compounds, carefully chosen based on Lipinski’s Rule of Five, bioavailability and drug-likeness scores. Additionally, our research pinpoints the top three core proteins through network pharmacology, assessing their potential for immune infiltration into cancer tissue and examining mRNA expression profiles across various pathological stages. Significantly, luteolin emerged as a primary SRC kinase inhibitor, displaying remarkable binding energy of −9.0 kcal/mol, comparable to the standard quinazoline inhibitor with binding energy of −9.5 kcal/mol. In addition, rigorous 100 nanosecond molecular dynamics simulations were performed on protein-compound complex, confirming their thermodynamic stability. Additionally, MM-PBSA also confirmed the docking results. Our in silico analysis suggested that luteolin holds promise as potent TC inhibitor, ushering in a new era in the quest for natural, low-risk therapeutic options for thyroid cancer, inspiring hope for patients and healthcare providers alike.

description: A general strategy is given for the classification of graphs of rational surface singularities. For each maximal rational double point configuration we investigate the possible multiplicities in the fundamental cycle. We classify completely certain types of graphs. This allows to extend the classification of rational singularities to multiplicity 8. We also discuss the complexity of rational resolution graphs.

Dephasing by a Continuous-Time Random Walk Process

description: Stochastic treatments of magnetic resonance spectroscopy and optical spectroscopy require evaluations of functions like , where t is time, Q(s) is the value of a stochastic process at time s, and the angular brackets denote ensemble averaging. This paper gives an exact evaluation of these functions for the case where Q is a continuous-time random walk process. The continuous time random walk describes an environment that undergoes slow, step-like changes in time. It also has a well-defined Gaussian limit, and so allows for non-Gaussian and Gaussian stochastic dynamics to be studied within a single framework. We apply the results to extract qubit-lattice interaction parameters from dephasing data of P-doped Si semiconductors (data collected elsewhere), and to calculate the two-dimensional spectrum of a three level harmonic oscillator undergoing random frequency modulations.

description: Multiply-connected traps for cold, neutral atoms fix vortex cores of quantum gases. Laguerre-Gaussian laser modes are ideal for such traps due to their phase stability. We report theoretical calculations of the Bose-Einstein condensation transition properties and thermal characteristics of neutral atoms trapped in multiply connected geometries formed by Laguerre-Gaussian LG{p}{l} beams. Specifically, we consider atoms confined to the anti-node of a LG{0}{1} laser mode detuned to the red of an atomic resonance frequency, and those confined in the node of a blue-detuned LG{1}{1} beam. We compare the results of using the full potential to those approximating the potential minimum with a simple harmonic oscillator potential. We find that deviations between calculations of the full potential and the simple harmonic oscillator can be up to 3%-8% for trap parameters consistent with typical experiments.

description: We consider a random diffusion dynamics for an infinite system of hard spheres of two different sizes evolving in ℝd, its reversible probability measure, and its projection on the subset of the large spheres. The main feature is the occurrence of an attractive short-range dynamical interaction --- known in the physics literature as a depletion interaction -- between the large spheres, which is induced by the hidden presence of the small ones. By considering the asymptotic limit for such a system when the density of the particles is high, we also obtain a constructive dynamical approach to the famous discrete geometry problem of maximisation of the contact number of n identical spheres in ℝd. As support material, we propose numerical simulations in the form of movies.

description: We consider the mass-dependent aggregation process (k+1)X -> X, given a fixed number of unit mass particles in the initial state. One cluster is chosen proportional to its mass and is merged into one either with k-neighbors in one dimension, or -- in the well-mixed case -- with k other clusters picked randomly. We find the same combinatorial exact solutions for the probability to find any given configuration of particles on a ring or line, and in the well-mixed case. The mass distribution of a single cluster exhibits scaling laws and the finite size scaling form is given. The relation to the classical sum kernel of irreversible aggregation is discussed.

Radio-loud Magnetars as Detectors for Axions and Axion-like Particles

description: We show that, by studying the arrival times of radio pulses from highly-magnetized transient beamed sources, it may be possible to detect light pseudo-scalar particles, such as axions and axion-like particles, whose existence could have considerable implications for the strong-CP problem of QCD as well as the dark matter problem in cosmology. Specifically, such light bosons may be detected with a much greater sensitivity, over a broad particle mass range, than is currently achievable by terrestrial experiments, and using indirect astrophysical considerations. The observable effect was discussed in Chelouche & Guendelman (2009), and is akin to the Stern-Gerlach experiment: the splitting of a photon beam naturally arises when finite coupling exists between the electro-magnetic field and the axion field. The splitting angle of the light beams linearly depends on the photon wavelength, the size of the magnetized region, and the magnetic field gradient in the transverse direction to the propagation direction of the photons. If radio emission in radio-loud magnetars is beamed and originates in regions with strong magnetic field gradients, then splitting of individual pulses may be detectable. We quantify the effect for a simplified model for magnetars, and search for radio beam splitting in the 2\,GHz radio light curves of the radio loud magnetar XTE\,J1810-197.

description: Different computational scheme for calculating surface integrals in anisotropic Brillouin zones are compared. The example of the transport distribution function (plasma frequency) of the thermoelectric Material \BiTe near the band edges will be discussed. The layered structure of the material together with the rhombohedral symmetry causes a strong anisotropy of the transport distribution function for the directions in the basal (in-plane) and perpendicular to the basal plane (out-of-plane). It is shown that a thorough reciprocal space integration is necessary to reproduce the in-plane/out-of-plane anisotropy. A quantitative comparison can be made at the band edges, where the transport anisotropy is given in terms of the anisotropic mass tensor.

description: In 2020, clinical services noted an unexpected increase in functional tic disorders, which coincided with the timing of the COVID-19 pandemic. Evidence suggests that functional symptoms and tic disorders have a significant impact on family functioning and child and parent quality of life. However, little is currently known of the impact of a functional tics (FTs) diagnosis in adolescence, both on the young person and their family. The current qualitative study explores adolescent and parent experiences of a FTs diagnosis, associated symptoms, and post-diagnostic support. Seven females aged between 12 and 18 years with a formal FTs diagnosis and eight parents were recruited through Tourette’s Action, a UK-based charity concerning Tourette syndrome. Participants took part in individual semi-structured interviews via Microsoft Teams. Transcribed interviews were analysed using a reflexive Thematic Analysis. Themes generated from adolescent and parent interviews included (1) blamed, disbelieved, discounted, (2) fighting for help, (3) professional and community support and (4) changes in identity and relationships. The findings emphasise the importance of psychoeducation encompassing FTs and young peoples’ holistic needs, support to develop personalised strategies for management of FTs and interacting additional needs, alongside an increased public and professional understanding of FTs to aid stigma reduction. Functional tics have a significant impact on adolescent and familial wellbeing and functioning.Adolescents with functional tics and their families report experiences of stigma from public and professionals.An improved understanding of functional tics for rehabilitation professionals is vital to aid timely diagnoses and post-diagnostic support, including the provision of psychoeducation.Psychological support and community support are reported as helpful interventions for functional tics.

description: We make detailed theoretical predictions for the assembly properties of the Local Group (LG) in the standard LambdaCDM cosmological model. We use three cosmological N-body dark matter simulations from the CLUES project, which are designed to reproduce the main dynamical features of the matter distribution down to the scale of a few Mpc around the LG. Additionally, we use the results of an unconstrained simulation with a sixty times larger volume to calibrate the influence of cosmic variance. We characterize the Mass Aggregation History (MAH) for each halo by three characteristic times, the formation, assembly and last major merger times. A major merger is defined by a minimal mass ratio of 10:1. We find that the three LGs share a similar MAH with formation and last major merger epochs placed on average \approx 10 - 12 Gyr ago. Between 12% and 17% of the halos in the mass range 5 x 10^11 Msol/h < M_h < 5 x 10^12 Msol/h have a similar MAH. In a set of pairs of halos within the same mass range, a fraction of 1% to 3% share similar formation properties as both halos in the simulated LG. An unsolved question posed by our results is the dynamical origin of the MAH of the LGs. The isolation criteria commonly used to define LG-like halos in unconstrained simulations do not narrow down the halo population into a set with quiet MAHs, nor does a further constraint to reside in a low density environment. The quiet MAH of the LGs provides a favorable environment for the formation of disk galaxies like the Milky Way and M31. The timing for the beginning of the last major merger in the Milky Way dark matter halo matches with the gas rich merger origin for the thick component in the galactic disk. Our results support the view that the specific large and mid scale environment around the Local Group play a critical role in shaping its MAH and hence its baryonic structure at present.

description: Anisotropic viscous drag is usually believed to be a requirement for the low Reynolds number locomotion of slender bodies such as flagella and cilia. Here we show that locomotion under isotropic drag is possible for extensible slender bodies. After general considerations, a two-ring swimmer and a model dinoflagellate flagellum are studied analytically to illustrate how extensibility can be exploited for self-propulsion without drag anisotropy. This new degree of freedom could be useful for some complex swimmer geometries and locomotion in complex fluid environments where drag anisotropy is weak or even absent.

description: Constraining the spatial and thermal structure of the gaseous component of circumstellar disks is crucial to understand star and planet formation. Models predict that the [Ne II] line at 12.81 μm detected in young stellar objects with Spitzer traces disk gas and its response to high energy radiation, but such [Ne II] emission may also originate in shocks within powerful outflows. To distinguish between these potential origins for mid-infrared [Ne II] emission and to constrain disk models, we observed 32 young stellar objects using the high resolution (R~30000) mid-infrared spectrograph VISIR at the VLT. We detected the 12.81 μm [Ne II] line in 12 objects, tripling the number of detections of this line in young stellar objects with high spatial and spectral resolution spectrographs. We obtain the following main results: a) In Class I objects the [Ne II] emission observed from Spitzer is mainly due to gas at a distance of more than 20-40 AU from the star, where neon is, most likely, ionized by shocks due to protostellar outflows. b) In transition and pre-transition disks, most of the emission is confined to the inner disk, within 20-40 AU from the central star. c) Detailed analysis of line profiles indicates that, in transition and pre-transition disks, the line is slightly blue-shifted (2-12 km s{^-1}) with respect to the stellar velocity, and the line width is directly correlated with the disk inclination, as expected if the emission is due to a disk wind. d) Models of EUV/X-ray irradiated disks reproduce well the observed relation between the line width and the disk inclination, but underestimate the blue-shift of the line.

description: The idea of computing Matveev complexity by using Heegaard decompositions has been recently developed by two different approaches: the first one for closed 3-manifolds via crystallization theory, yielding the notion of Gem-Matveev complexity; the other one for compact orientable 3-manifolds via generalized Heegaard diagrams, yielding the notion of modified Heegaard complexity. In this paper we extend to the non-orientable case the definition of modified Heegaard complexity and prove that for closed 3-manifolds Gem-Matveev complexity and modified Heegaard complexity coincide. Hence, they turn out to be useful different tools to compute the same upper bound for Matveev complexity.

description: Informally, a set of abstractions of a state space S is additive if the distance between any two states in S is always greater than or equal to the sum of the corresponding distances in the abstract spaces. The first known additive abstractions, called disjoint pattern databases, were experimentally demonstrated to produce state of the art performance on certain state spaces. However, previous applications were restricted to state spaces with special properties, which precludes disjoint pattern databases from being defined for several commonly used testbeds, such as Rubiks Cube, TopSpin and the Pancake puzzle. In this paper we give a general definition of additive abstractions that can be applied to any state space and prove that heuristics based on additive abstractions are consistent as well as admissible. We use this new definition to create additive abstractions for these testbeds and show experimentally that well chosen additive abstractions can reduce search time substantially for the (18,4)-TopSpin puzzle and by three orders of magnitude over state of the art methods for the 17-Pancake puzzle. We also derive a way of testing if the heuristic value returned by additive abstractions is provably too low and show that the use of this test can reduce search time for the 15-puzzle and TopSpin by roughly a factor of two.

description: This paper presents a new classifier combination technique based on the Dempster-Shafer theory of evidence. The Dempster-Shafer theory of evidence is a powerful method for combining measures of evidence from different classifiers. However, since each of the available methods that estimates the evidence of classifiers has its own limitations, we propose here a new implementation which adapts to training data so that the overall mean square error is minimized. The proposed technique is shown to outperform most available classifier combination methods when tested on three different classification problems.
Background: - Adolescence is a nutritionally vulnerable period of life because of the dramatic changes in physical growth and development and the change of life style and food habits that affect both nutrient intake and needs. Inadequate quality and quantity of food are the prime determinants of nutrition. However studies are limited regarding adolescent nutrition and there is very little information on the adequacy of dietary intake among adolescents. Objective: - To estimate the level of macro and micro nutrient intake and to evaluate prevalence of inadequacy among adolescent girls 10-19 years. Method; - A community based cross-sectional study was conducted in Damot Gale district, Woliyta zone, SNNP Region. Data were collected from 288 female adolescents after random selection from six kebeles. Face to face interview was conducted using Repeated multiple pass 24-hour dietary recall method. Data on all foods and drinks consumed by the adolescents in the previous 24 hours before interview was obtained DISPOSAL

description: The rapid increase in the use of plastic materials in the recent years led to the

accumulation of extreme amounts of plastic waste. Thermoplastics such as PET,

PE, PP, PS and PVC as well as materials that derived from these are the type of

plastic most used and consequently create environmental problems.

Landfill, incineration and recycling remains the primary options for solid waste

management. One critical determinant of the acceptability of these options is the

different health risks associated with each.

The plastic waste that burnt and dumped in landfill sites can be recycled and

used for different purpose. This includes the use of waste plastic in construction

of asphalt road. By recycling waste plastic, it is possible to protect the

environment from contamination.

Using waste plastic in asphalt road construction as an aggregate binder is one of

the recent plastic waste approach. This will help us to avoid the environmental

pollution from open-air burning and landfill of plastic waste.

title: Using single-molecule microscopy to investigate macromolecular complexes from NER to Translation

description: DNA is subjected to many forces within cells. In prokaryotes, those range from the supercoiling of the DNA to the impact of macromolecular complexes like the replisome. Lesions on DNA induce changes in DNA structure and/or flexibility. Some of those are recognized and repaired by Nucleotide Excision Repair (NER). NER is a DNA damage repair pathway composed of a few proteins but can recognize and process a plethora of lesion types. It has been proposed that NER recognizes local changes in the structure or flexibility of the DNA at lesion sites. This thesis aims to assess the effect of structural modifications of the DNA on the ability of NER proteins to recognize the damage, as well as assess the effect of newly found inhibitors on the binding of a NER protein. By using optical traps, we were able to alter the tension applied to a single molecule of double-stranded DNA and assess how DNA distortion affects the kinetics of NER proteins at the single-molecule level. Those changes in the tension altered the binding of fluorescently tagged UvrA and UvrB, the first two responders to damage in NER. The more tension applied to the DNA strand, the faster the attachment and the longer the lifetime of UvrA on the DNA. Similarly, UvrB is recruited more often by UvrA when the tension is increased. This sheds light, for the first time, on how these proteins recognise DNA damage, suggesting these proteins recognize changes in the structure of the DNA in a systemic manner instead of specific alterations for each lesion type. Furthermore, we assessed the effect of various NER inhibitors on the binding of UvrA to the DNA and highlighted potential modes of action. Aprotinin increased the affinity of UvrA to the DNA, while ATBC, Bemcentinib, L-Thyroxine and Dienestrol decreased the affinity of UvrA to the DNA. Interestingly, Dienestrol seems to have a dual mode of action by binding to the UvrA molecule and reducing its affinity for the DNA, as well as binding to the DNA molecule, hindering UvrA binding. Prokaryotic NER inhibitors are of great interest as they could be used as a novel family of antimicrobials and potentially be exploited in cancer therapy in combination with DNA-damaging agents to inhibit the growth of bacterial infections. The discovery of novel antimicrobials is of the foremost importance as antimicrobial resistance is rapidly spreading. With most antibiotics targeting the ribosome, a third aim of this thesis was to deepen the understanding of one understudied aspect of translation which is the impact of near-cognate tRNA in the elongation step of the translation. In this thesis I outline a series of experiments that allowed us to stall ribosomes at a specific codon, the first step to assess codon/near-cognate tRNA interactions.

description: Berg, Christensen and Ressel prove that the closure of the cone of sums of squares in the ring of real polynomials in the topology induced by the $\ell_1$-norm is equal to the cone consisting of all polynomials which are non-negative on the hypercube $[-1,1]^n$. The result is deduced as a corollary of a general result which is valid for any commutative semigroup. In later work Berg and Maserick and also Berg, Christensen and Ressel establish an even more general result, for a commutative semigroup with involution, for the closure of the cone of sums of squares of symmetric elements in the weighted $\ell_1$-seminorm topology associated to an absolute value. In the present paper we give a new proof of these results which is based on Jacobi's representation theorem. At the same time, we use Jacobi's representation theorem to extend these results from sums of squares to sums of 2d-powers, proving, in particular, that for any integer $d>0$, the closure of the cone of sums of 2d-powers in the ring of real polynomials in the topology induced by the $\ell_1$-norm is equal the cone consisting of all polynomials which are non-negative on the hypercube $[-1,1]^n$.

description: Background: Cholera is a diarrheal disease caused by infection of the intestine with the gramnegative

bacteria vibrio cholera, either type o1 or o139. A single case of Cholera initiates outbreak

investigation in Ethiopia. Kolfe keraniyo sub-city Public Health Emergency Management reported

two Cholera cases on 20 September 2017. Two of the sample investigated by culture and stool RDT

kit confirmed that positive for vibrio cholera o1. The index case was 55 years old woman from

woreda one kolfe keraniyo sub-city. We aimed to identify the risk factor for the occurrence of the

cholera outbreak and institute appropriate measures

Method: we conducted cholera outbreak investigation in woreda1, 2,3,5,9 and 13 of kolfe keraniyo

sub city, Addis Ababa town from September 20, 2017-January7, 2017. We defined suspected cases of

cholera as occurrence of acute watery diarrhea, with or without vomiting, in a patient aged ≥5 years

living in study area. Unmatched case control study design was used and we included all of the

identified cases (19) during the course of the outbreak and recruited 38 controls with 2:1 control to

case ratio. We searched new cases in health facilities. We assessed houses of cases and holly waters.

Structured questionnaire was used to collect data for case control study and using line list

description: Markov decision processes capture sequential decision making under uncertainty, where an agent must choose actions so as to optimize long term reward. The paper studies efficient reasoning mechanisms for Relational Markov Decision Processes (RMDP) where world states have an internal relational structure that can be naturally described in terms of objects and relations among them. Two contributions are presented. First, the paper develops First Order Decision Diagrams (FODD), a new compact representation for functions over relational structures, together with a set of operators to combine FODDs, and novel reduction techniques to keep the representation small. Second, the paper shows how FODDs can be used to develop solutions for RMDPs, where reasoning is performed at the abstract level and the resulting optimal policy is independent of domain size (number of objects) or instantiation. In particular, a variant of the value iteration algorithm is developed by using special operations over FODDs, and the algorithm is shown to converge to the optimal policy.

Searching for Bayesian Network Structures in the Space of Restricted Acyclic Partially Directed Graphs

description: Although many algorithms have been designed to construct Bayesian network structures using different approaches and principles, they all employ only two methods: those based on independence criteria, and those based on a scoring function and a search procedure (although some methods combine the two). Within the score+search paradigm, the dominant approach uses local search methods in the space of directed acyclic graphs (DAGs), where the usual choices for defining the elementary modifications (local changes) that can be applied are arc addition, arc deletion, and arc reversal. In this paper, we propose a new local search method that uses a different search space, and which takes account of the concept of equivalence between network structures: restricted acyclic partially directed graphs (RPDAGs). In this way, the number of different configurations of the search space is reduced, thus improving efficiency. Moreover, although the final result must necessarily be a local optimum given the nature of the search method, the topology of the new search space, which avoids making early decisions about the directions of the arcs, may help to find better local optima than those obtained by searching in the DAG space. Detailed results of the evaluation of the proposed search method on several test problems, including the well-known Alarm Monitoring System, are also presented.
Limit experiments of GARCH

description: GARCH is one of the most prominent nonlinear time series models, both widely applied and thoroughly studied. Recently, it has been shown that the COGARCH model (which was introduced a few years ago by Klüppelberg, Lindner and Maller) and Nelson's diffusion limit are the only functional continuous-time limits of GARCH in distribution. In contrast to Nelson's diffusion limit, COGARCH reproduces most of the stylized facts of financial time series. Since it has been proven that Nelson's diffusion is not asymptotically equivalent to GARCH in deficiency, in the present paper, we investigate the relation between GARCH and COGARCH in Le Cam's framework of statistical equivalence. We show that GARCH converges generically to COGARCH, even in deficiency, provided that the volatility processes are observed. Hence, from a theoretical point of view, COGARCH can indeed be considered as a continuous-time equivalent to GARCH. Otherwise, when the observations are incomplete, GARCH still has a limiting experiment, which we call MCOGARCH, which is not equivalent, but nevertheless quite similar, to COGARCH. In the COGARCH model, the jump times can be more random than for the MCOGARCH, a fact practitioners may see as an advantage of COGARCH.
