The expression of hematopoietic progenitor cell antigen CD34 is regulated by DNA methylation in a site-dependent manner in gastrointestinal stromal tumours.docx

description: The anatomic site-dependent expression of hematopoietic progenitor cell antigen CD34 is a feature of gastrointestinal stromal tumours (GISTs). The basis for the differential CD34 expression is only incompletely understood. This study aimed at understanding the regulation of CD34 in GISTs and clarification of its site-dependent expression. Two sample sets of primary GISTs were interrogated including 52 fresh-frozen and 134 paraffin-embedded and formalin-fixed specimens. DNA methylation analysis was performed by HumanMethylation450 BeadChip array in three cell lines derived from gastric and intestinal GISTs, and differentially methylated CpG sites were established upstream of CD34. The methylation degree was further quantified by pyrosequencing, and inverse correlation with CD34 mRNA and protein abundance was revealed. The gene's expression could be activated upon induction of DNA hypomethylation with 5-aza-2'-deoxycytidine in GIST-T1 cells. In patient samples, a strong inverse correlation of DNA methylation degree with immunohistochemically evaluated CD34 expression was documented. Both CD34 expression and DNA methylation levels were specific to the tumours' anatomic location and mutation status. A constant decrease in methylation levels was observed ranging from almost 100% hypermethylation in intestinal GISTs from duodenum to hypomethylation in rectum. CD34 was heavily methylated in gastric PDGFRA-mutant GISTs in comparison to hypomethylated KIT-mutant counterparts. Next to CD34 hypermethylation, miR-665 was predicted and experimentally confirmed to target CD34 mRNA in GIST-T1 cells. Our results suggest that CD34 expression in GISTs may undergo a complex control by DNA methylation and miR-665. Differential methylation and expression of CD34 in GISTs along the gastrointestinal tract axis and in tumours that harbour different gain-of-function mutations suggest the origin from different cell populations in the gastrointestinal tract.

description: We have calculated quark and anti-quark relaxation time by considering different possible elastic and inelastic scatterings in the medium. Comparative role of these elastic and inelastic scatterings on different transport coefficients are explored. The quark-meson effective interaction Lagrangian density in the framework of Nambu--Jona-Lasinio model is used for calculating both type of scatterings. Owing to a kinetic threshold, inelastic scatterings can only exist beyond the Mott line in temperature and chemical potential plane, whereas elastic scatterings occur in the entire plane. Interestingly, the strength of inelastic scatterings near and above Mott line becomes so strong that medium behaves like a perfect fluid, in that all transport coefficients become very small.

description: Currently, cardiovascular diseases are the leading cause of global mortality, while diabetes mellitus remains an important cause of cardiovascular morbidity. A recent study showed that patients with diabetes mellitus treated with mineralocorticoid receptor antagonists have improved coronary microvascular function, leading to improved diastolic dysfunction. In this study, we evaluated the influence of acute administration of spironolactone on myocardial function in rats with streptozotocin-induced diabetes mellitus, with special emphasis on cardiodynamic parameters in diabetic rat hearts. The present study was carried out on 40 adult male Wistar albino rats (8 weeks old). Rats were randomly divided into 4 groups (10 animals per group): healthy rats treated with 0.1 μmol/L of spironolactone, diabetic rats treated with 0.1 μmol/L of spironolactone, healthy rats treated with 3 μmol/L of spironolactone, and diabetic rats treated with 3 μmol/L of spironolactone. Different, dose-dependent, acute responses of spironolactone treatment on isolated, working diabetic and healthy rat heart were observed in our study. In healthy rats, better systolic function was achieved with higher spironolactone dose, while in diabetic rats, similar effects of low and high spironolactone dose were observed.

ММП необходимы как в процессах циклической смены фаз в эндометрии вне беременности, так и при имплантации эмбриона и развитии плаценты. Нарушение регуляции их активности участвует в патогенезе разнообразных состояний: от аномальных маточных кровотечений (АМК), неоплазии эндометрия и яичников до неблагоприятных исходов беременности. Определение нормального и патологического паттерна концентраций ММП и их тканевых ингибиторов (TIMP) предположительно может быть использовано в качестве прогностического маркера риска невынашивания беременности или преждевременных родов, а также неблагоприятных попыток ЭКО.

description: We investigate whether dual strings could be solutions of the magnetohydrodynamics equations in the limit of infinite conductivity. We find that the induction equation is satisfied, and we discuss the Navier-Stokes equation (without viscosity) with the Lorentz force included. We argue that the dual string equations (with a non-universal maximum velocity) should describe the large scale motion of narrow magnetic flux tubes, because of a large reparametrization (gauge) invariance of the magnetic and electric string fields. It is shown that the energy-momentum tensor for the dual string can be reinterpreted as an energy-momentum tensor for magnetohydrodynamics, provided certain conditions are satisfied. We also give a brief discussion of the case when magnetic monopoles are included, and indicate how this can lead to a non-relativistic "electrohydrodynamics" picture of confinement.

description: A sample of Lambda's produced in 2 A*GeV Ni + Cu collisions has been obtained with the EOS Time Projection Chamber at the Bevalac. Low background in the invariant mass distribution allows for the unambiguous demonstration of Lambda directed flow. The transverse mass spectrum at mid-rapidity has the characteristic shoulder-arm shape of particles undergoing radial transverse expansion. A linear dependence of Lambda multiplicity on impact parameter is observed, from which a total Lambda + Sigma^0 production cross section of $112 +/- 24 mb is deduced. Detailed comparisons with the ARC and RVUU models are made.

description: We propose to manipulate the statistic properties of the photons transport nonreciprocally via quadratic optomechanical coupling. We present a scheme to generate quadratic optomechanical interactions in the normal optical modes of a whispering-gallery-mode (WGM) optomechanical system by eliminating the linear optomechanical couplings via anticrossing of different modes. By optically pumping the WGM optomechanical system in one direction, the effective quadratic optomechanical coupling in that direction will be enhanced significantly, and nonreciprocal photon blockade will be observed consequently. Our proposal has potential applications for the on-chip nonreciprocal single-photon devices.

We demonstrate that the prescription based on the {\it on-shell} renormalization conditions is not consistent with the Ward-Takahashi Identities and leads to gauge dependent physical amplitudes. A simple scheme is proposed that satisfies all theoretical requirements and is very convenient for practical calculations.

description: The styrene–maleic acid (SMA) copolymers enable a detergent-free extraction of membrane proteins from lipid bilayers yielding stable water-soluble nanocontainers with lipid-encased proteins. Here, we demonstrate the ability of the SMA copolymer to extract a complex of interacting membrane proteins from proteoliposomes, namely the archaeal sensory rhodopsin II from Natronomonas pharaonis, NpSRII, in complex with its transducer, NpHtrII. The NpSRII/NpHtrII complexes retained their structural integrity within SMA lipid particles as revealed by diverse biophysical techniques. Pulse electron paramagnetic resonance data showed the SMA-encased NpSRII/NpHtrII complexes as native-like 2[thin space (1/6-em)]:[thin space (1/6-em)]2 dimers with a distance between NpSRII sites 159 according to the “V”-shaped conformation found in a crystal structure.

description: The dispersion relation in matter of ultrahigh-energy neutrinos above the pole of the $W$ resonance ($E_ν \gsim {\rm 10}^{7} {\rm GeV} $), is studied. We perform our calculation using the real-time formulation of Thermal Field Theory in which the massless limit for the $W$ boson is taken. The range of active-to-sterile neutrino oscillation parameters for which there is significant mixing enhancement during propagation through the interior of the Earth, and therefore significant attenuation of neutrino beams in the Earth at high energies, is estimated. Finally, this range is considered in view of the cosmological and astrophysical constraints.

The Continuous Stochastic Gradient Method
Creators: name: Uihlein, Andrian
Publisher: name: Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)
Year: 2024

description: We consider a class of optimization problems in which the objective function requires the computation of an expected value of a hard to evaluate property. Such structures arise in probabilistic settings, e.g., expected values in optimization under uncertainty, as well as fully deterministic contexts, e.g., optimizing a design for a (possibly infinite) set of scenarios. Therefore, both stochastic and deterministic optimization schemes have been considered to solve such problems. The latter typically rely on a fixed quadrature rule to approximate all appearing integrals numerically. As a result, the associated computational cost may render such approaches numerically infeasible in complex settings. Moreover, discretization can lead to artificial local solutions emerging in the problem, if the corresponding quadrature rule is not chosen carefully. Contrary, stochastic sample based methods do not suffer from this problem and provide a computationally cheap alternative. However, these schemes are typically limited to objective functions of very simple structure, i.e., minimizing an expected value. Settings in which the objective consists of several integrals, possibly coupled by nonlinear functions, are beyond the scope of such techniques. In this work, we consider continuous stochastic optimization approaches, specifically, a continuous stochastic gradient (CSG) scheme. To keep the numerical effort per iteration low, these methods also rely on random gradient samples instead of full integrals. However, unlike traditional stochastic sample based strategies, the gradient information is stored over the course of iterations. Thus, by calculating suitable design dependent integration weights, a convex combination of old gradient samples is used to build an approximation to the full gradient. We show that the approximation error almost surely converges to zero during the optimization process. As a result, we prove that CSG admits the same convergence results as a full gradient scheme, i.e., convergence for constant step sizes and line search techniques based on the continuous stochastic approximations. Moreover, it means that CSG is not restricted to the minimization of simple expected values and can instead deal with arbitrary combinations of integrals and Lipschitz continuous functions in the objective. In this sense, CSG can be considered as a hybrid of stochastic gradient methods and a classical gradient descent scheme. Several methods to obtain the aforementioned integration weights in practice are presented and discussed. Furthermore, we provide a full theoretical convergence analysis of CSG and perform numerical experiments, covering all important aspects of continuous stochastic optimization methods. For several large scale applications from the field of topology optimization, the proposed schemes are compared to different optimization techniques known from literature.

In healthy rats, better systolic function was achieved with higher spironolactone dose, while in diabetic rats, similar effects of low and high spironolactone dose were observed.

description: The heterogeneity of biomass characteristics is a major challenge for all thermochemi-cal conversion processes. This work describes the development from the idea to a working prototype for a system with which online fuel characteristics can be identified. The idea as well as the scientific work are based on the following hypothesis: If warm air flows through a solid bed of biogenic fuels, it interacts with the solid bed during the flow. The physical processes occurring in this process measurably change the proper-ties of the air. Based on these changes, it is possible to draw conclusions about relevant fuel properties (water content, bulk density) and the type of fuel. In a first step, a test rig was developed with which defined fuel samples can be dried and the changes in temperature, water content and pressure drop can be analyzed. First, a screening test series with a wide range of feedstocks (wood chips, forest resi-dues, wood pellets, saw dust, corn cobs, biochar from digestate and aluminum oxide spheres) was conducted to create an initial data basis. Through this series of tests, the general feasibility of the idea could be demonstrated. The data from the test series were used to develop an evaluation logic by combining data-based and analytical approach-es. Based on this preliminary work, a prototype was developed and connected directly to an automatically fed grate furnace in the Fraunhofer UMSICHT technical center. After commissioning of the prototype, test series were carried out with wood chips, for-est residues, saw dust and wood pellets. These tests created the data basis for training and evaluating a machine learning algorithm. For evaluation the furnace was alternately fed with wood chips, forest residues and wood pellets. Regarding the accuracy, it could be shown that the identification of the feedstock succeeds with a probability of about 90% for wood chips and forest residues and 100% for pellets. The determination of the water content and the bulk density showed that the orders of magnitude were correctly determined. The deviation in the water content was on average between 1.7% and 4.1% in absolute terms. The precision in the determination of the bulk density lies with a rela-tive error of 10.42% for wood chips, 15.41% for forest residues and 5.98% for wood pellets. In the end, the hypothesis was confirmed, and the basic idea was turned into a working prototype.

description: The Serpens filament, as one of the nearest infrared dark clouds, is regarded as a pristine filament at a very early evolutionary stage of star formation. In order to study its molecular content and dynamical state, we mapped this filament in seven species. Among them, HCO$^{+}$, HNC, HCN, and CS show self-absorption, while C$^{18}$O is most sensitive to the filamentary structure. A kinematic analysis demonstrates that this filament forms a velocity-coherent (trans-)sonic structure, a large part of which is one of the most quiescent regions in the Serpens cloud. Widespread C$^{18}$O depletion is found throughout the Serpens filament. Based on the Herschel dust-derived H$_{2}$ column density map, the line mass of the filament is 36--41~M$_{\odot}$~pc$^{-1}$, and its full width at half maximum is 0.17$\pm$0.01~pc, while its length is ~1.6~pc. The inner radial column density profile of this filament can be well fitted with a Plummer profile with an exponent of 2.2$\pm$0.1, a scale radius of $0.018\pm 0.003$ pc, and a central density of $(4.0\pm 0.8)\times 10^{4}$~cm$^{-3}$. The Serpens filament appears to be slightly supercritical. The widespread blue-skewed HNC and CS line profiles and HCN hyperfine line anomalies across this filament indicate radial infall in parts of the Serpens filament. C$^{18}$O velocity gradients also indicate accretion flows along the filament. The velocity and density structures suggest that such accretion flows are likely due to a longitudinal collapse parallel to the filament's long axis. Both the radial infall rate and the longitudinal accretion rate along the Serpens filament are lower than all previously reported values in other filaments. This indicates that the Serpens filament lies at an early evolutionary stage when collapse has just begun, or that thermal and non-thermal support are effective in providing support against gravity.

description: In an isotropic and homogeneous Hubble expansion, all transverse motion is peculiar. Like the radial peculiar velocities of galaxies, transverse peculiar velocities are a means to trace the density of matter that does not rely on light tracing mass. Unlike radial peculiar velocity measurements that require precise redshift-independent distances in order to distinguish between the Hubble expansion and the observed redshift, transverse peculiar velocities can be measured using redshifts alone as a proxy for distance. Extragalactic proper motions can therefore directly measure peculiar velocities and probe the matter power spectrum. Here we develop two-point transverse velocity correlation statistics and demonstrate their dependence on the matter power spectrum. We predict the power in these correlation statistics as a function of the physical separation, angular separation, and distance of pairs of galaxies and demonstrate that the effect of large scale structure on transverse motions is best measured for pairs of objects with comoving separations less than about 50 Mpc. Transverse peculiar velocities induced by large scale structure should be observable as proper motions using long baseline radio interferometry or space-based optical astrometry.

description: The importance of the Hurwitz Metzler matrices and the Hurwitz symmetric matrices can be appreciated in different applications: communication networks, biology and economics are some of them. In this paper, we use an approach of differential topology for studying such matrices. Our results are as follows: the space of the $n\times n$ Hurwitz symmetric matrices has a product manifold structure given by the space of the $(n-1) \times (n-1)$ Hurwitz symmetric matrices and the euclidean space. Additionally we study the space of Hurwitz Metzler matrices and these ideas let us do an analysis of robustness of Hurwitz Metzler matrices. In particular, we study the Insulin Model as application.

Detecting fundamental structures of the interstellar medium with machine learning algorithms
Creators: name: Bernreuther, Dominic
Publisher: name: Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)
Year: 2024

description: The detection and classification of fundamental structures of the interstellar medium (ISM) is tedious but tremendously important work for astronomers. Structures like supernova remnants (SNRs) shape and drive the ISM and have a big impact on evolving galaxies. Those fundamental structures are of bubble-like shape. Finding these bubble-like structures is therefore crucial in the study of galaxy evolution and of the universe in general. Currently, the detection of those bubble-like structures is done mainly by eye, by manually examining astronomical images. In the era of machine learning algorithms, however, this process can be automized. In this thesis, we present an automated detection and classification pipeline for bubble-like structures based on multi-wavelengths images. The pipeline is called BScan and makes use of two neural networks: a convolutional neural network (CNN) is used for detecting the bubble-like structures in the images and a fully connected neural network (FCNN) is used to classify the detected structures. Both networks are used and combined by classical algorithms. The CNN is part of the nested boxes detection algorithm (NBDA), which scans the available images, and the FCNN then uses the output of the NBDA. The configuration is done via a configuration file where all hyperparameters can be set. In areas of isolated structures or less crowded regions, BScan performs relatively well by localizing already cataloged sources with an average distance of 36arcsec to the source center given by the catalog. The radius of the detected strucutre, however, is systematically overestimated. In highly crowded regions BScan may detect multiple but separated structures as one single structure. BScan also shows some inconsistencies in detecting similar bubble-like structures in images of similar or even the same resolution. The classification has a small estimated error of around 0.1% but is heavily dependent on the NBDA. There are different approaches using different techniques to address the idea of automated structure detection, but yet there has been no attempt to combine the detection and classification aspect in one process. With some further developments and improvements, the idea of BScan could set new standards in detecting fundamental structures of the ISM and could be a great tool for astronomy in the future.

description: Recently, the CDF collaboration has reported a measurement of the CP asymmetry in the $B\toψK_S$ decay: $a_{ψK_S}=0.79^{+0.41}_{-0.44}$. We analyze the constraints that follow from this measurement on the size and the phase of contributions from new physics to $B-\barB$ mixing. Defining the relative phase between the full $M_{12}$ amplitude and the Standard Model contribution to be $2θ_d$, we find a new bound: $\sin2θ_d\gsim-0.6 (-0.87)$ at one sigma (95% CL). Further implications for the CP asymmetry in semileptonic B decays are discussed.

Kinetic models for label switching and stochastic gradient descent
Creators: name: Rossi, Alex
Publisher: name: Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU)
Year: 2024

description: In this thesis we develop a new model, which consists in a linear integro-differential equation. This is introduced considering the structure of various models of the kinetic theory, with different applications, like, for instance, in the analysis of populations, material science and the stochastic gradient descent (SGD), the most famous algorithm for the stochastic optimisation. After the analysis of these motivations and the introduction of essential theoretical concepts, we present the main model and its principal properties: existence and uniqueness of measure-valued solutions, existence of stationary states and some features of such states. Moreover, we deal with the limit equation, in case the interaction parameter tends to infinity (grazing collisions limit). If we take into account the SGD-interpretation and the interaction parameter depends on time, we consider the limit of the solution to the equation, as time tends to infinity. Then, we add some diffusion to the main equation in order to create a stochastic gradient Langevin dynamics-type model. We present the problem of propagation of chaos, which leads us to a nonlinear equation, the Vlasov equation, of which we analyse the well-posedness. To conclude, we expose some further unsolved problems and issues.
