title: Aspects of quark mass dependence in lattice QCD
Creators: name: Varnhorst, Lukas
Publisher: name: Bergische Universität Wuppertal
Year: 2020

description: The goals of the thesis where to calculate the quark mass dependencies of several observables.
 In a first part we determined the nucleon sigma terms and quark contents. We calculated the up, down, strange, and charm quark contents from first principles using lattice QCD. We used a perturbative heavy quark expansion to calculate the bottom and top quark contents. These expansion are expected to be valid for these two quark flavors. We checked their validity also in the case of the charm quark where the errors of the truncated perturbative expansion are expected to be larger then for the top and bottom quarks. We find that our lattice determination is in very good agreement with the perturbative calculation. A key part to our lattice calculation is that we employed several fermion actions in our analysis and leveraged the different advantages they offer for different parts of the calculation.
 For the calculation of the sigma terms we employed the Feynman-Hellmann method. Our results are consistent with other lattice determinations. Despite this, we find that recent phenomenological calculation (s. [115]) based on pion-nucleon scattering predict a slightly larger light sigma terms then most lattice calculations, including our own ab-inito calculation. It would be interesting to study the source of this discrepancy.
 Our results allow us to calculate the nucleon-Higgs coupling with an error of about 30 %. We believe that our results are of high relevance to direct dark matter detection experiments. It is remarkable that, in the  Nf = 6 theory, a large fraction of the Higgs nucleon coupling originates from the heavy quark flavors; while they contribute only through quantum fluctuations that are suppressed by their mass, their Higgs coupling is also large, because they are heavy. Both effects almost cancel.
 In a second part, we calculated the dependence of the kaon mass splitting on the light quark mass splitting and the electromagnetic charges of the light quarks. We where able to quantify the amount of violation of Dashen’s theorem. We used our result to infer the ratio of the light quark masses. The calculation was carried out in a partially quenched setup. While we estimated the error made by using this approximation, it would be interesting to carry out this calculation in a fully dynamic QED+QCD setting.

description: We consider the variational free energy approach for compressed sensing. We first show that the naïve mean field approach performs remarkably well when coupled with a noise learning procedure. We also notice that it leads to the same equations as those used for iterative thresholding. We then discuss the Bethe free energy and how it corresponds to the fixed points of the approximate message passing algorithm. In both cases, we test numerically the direct optimization of the free energies as a converging sparse-estimationalgorithm.

description: Room temperature local magnetoresistance in two-terminal scheme is reported. By employing 1.6 nm-thick MgO tunnel barrier, spin injection efficiency is increased, resulting in large non-local magnetoresistance. The magnitude of the non-local magnetoresistance is estimated to be 0.0057 ohm at room temperature. As a result, a clear rectangle signal is observed in local magnetoresistance measurement even at room temperature. We also investigate the origin of local magnetoresistance by measuring the spin accumulation voltage of each contact separately.

Combining API Patterns in Microservice Architectures: Artifacts, models, and dataset
Creators: name: Anonymous
Publisher: name: Zenodo
Year: 2023

description: There are many challenges in maintaining the desired quality of service levels in modern microservice and cloud applications. Numerous techniques and patterns, such as API Rate Limit, Load Balancing, and Request Bundle, have been suggested for API services and clients to improve quality properties related to performance and reliability. However, no study has measured the impact of these techniques and their combinations in a specific configuration, especially using a large distributed system workload setting. This paper empirically studies the effects of combining the API Rate Limit, Load Balancing, and Request Bundle patterns based on a realistic, third-party microservice-based application deployed in a private cloud and on the Amazon Web Services cloud (AWS) using 130 different configurations. We have run each configuration 500 times in the private cloud, totaling more than 4500 hours of runtime, and 200 times on AWS, totaling more than 3900 hours of runtime. We developed regression models from the collected data to predict the performance and reliability impacts of combining such techniques and patterns. We found that the models provide acceptable prediction errors below 30% on the private cloud and AWS. Further, we found that the models work best in highly reliable environments like AWS. In addition to the concrete analyses provided in our work, we propose a general and largely automated method that can be followed iteratively to evaluate similar techniques and patterns for their quality properties.

description: Hybrid capture-based target enrichment is often used for enrichment specific genes, exons and/or other genomic regions of interest in non-model organisms without a reference genome. Here we describe a workflow for designing baits suitable for orchid genomic hybridization. Starting by available Ophrys sphegodes and Phalaenopsis equestris genomes and transcriptomes we firstly selected 1,000bp and 500bp sliding windows respectively and 1,680,457 baits were designed (769,809 Ophrys baits; 910,648 Phalaenopsis baits) with a length 100bp, CG content between 20-50%. For excluding baits too variable (95%) Ophrys baits within 90-95% identity interval with Phalaenopsis genome and transcriptome, and viceversa, were filtered by BLASTN retaining only those mapping once. The resulting baits (13894 from Ophrys, 11907 from Phalaenopsis) were further tested for mapping on alternative genome and transcriptome through simulations with Bowtie2/samtools and 23.200 baits were finally selected for synthesis. As a testing ground, CAPSIM was used to simulate the dynamics of the capture process between the selected baits and some available orchid genomes/transcriptomes (Dendrobium catenatum, Apostasia shenzhenica, Orchis italica and Cymbidium faberi), by defining an Illumina sequencing of 150bp single-end reads. The simulation generates approx. 17,000 raw reads resulting from cross-hybridization with selected baits.

description: Vector inflation is a newly established model where inflation is driven by non-minimally coupled massive vector fields with a potential term. This model is similar to the model of chaotic inflation with scalar fields, except that for vector fields the isotropy of expansion is achieved either by considering a triplet of orthogonal vector fields or $N$ randomly oriented independent vector fields. We introduce a new version of vector inflation where the vector field has no potential term but is non-minimally coupled to gravity through the kinetic term. The non-minimal coupling is established by introducing the Einstein tensor besides the metric tensor within the kinetic term of the vector field.

PhenPath identifies biological functions underlying phenotypes

description: Co-occurrence of different phenotypes hampers the understanding of the molecular mechanisms characterizing diseases. While many resources focus on the relationship among phenotypes, diseases, and genes, little is known about the relevance of molecular functions and functional processes underlying the occurrence of phenotypes.
 To this aim, here we describe a new resource called PhenPath (phenpath.biocomp.unibo.it), recently published. PhenPath allows phenotype functional annotation, after an enrichment procedure of the functional annotation of the different phenotype/disease-associated genes. Functional annotations consider Gene Ontology (Molecular Function, Biological Process and Cellular Component), KEGG and Reactome pathways.
 PhenPath can be adopted to endow a disease (described with a set of phenotypes) with novel links to genes and functional terms, retrieved by intersecting the sets of genes and functional terms associated with the single phenotypes in PhenPath, as we proved in many study cases (e.g.: Rett syndrome, Tourette syndrome). We participated in the Critical Assessment of protein Function Annotation algorithms (CAFA) 4th edition using a method based on PhenPath, and the preliminary results of the experiment show that PhenPath is among the top-scoring methods.
 We propose our resource for directing scientific efforts, helping the diagnosis and retrieving new possible associations among biological processes and diseases.

description: Цель данного исследования состояла в проведении анализа, по данным литературы, влияния различных видов массажа на микроциркуляцию тканей пародонта. Были проанализированы 50 источников отечественной и зарубежной литературы, начиная с 2012 года по 2022 год. Систематический поиск литературы был выполнен с использованием баз данных PubMed, eLIBRARY, ВАК. В результате проведенного анализа было установлено, что в настоящее время физиотерапевтические методы являются одними из основных методов комплексного лечения заболеваний пародонта. Массаж десен обладает противовоспалительным эффектом, способен разрушать микробную биопленку и восстанавливать мик роциркуляторный гомеостаз. Рассмотрены методики различных видов массажа, их действие на ткани пародонта, отрицательные и положительные стороны. Применение массажа десен при заболеваниях пародонта является патогенетически обоснованным. Научно доказано, что выбор метода массажа зависит от клинической ситуации. Однако на сегодняшний день ни в отечественной, ни в зарубежной литературе нет единой точки зрения о предпочтении определенного метода массажа, что подчеркивает чрезвычайную актуальность дальнейшего исследования положительных и отрицательных сторон различных его методов.
description: The purpose of this study was to analyse the literature on the effect how various types of massage influence microcirculation of periodontal tissues. 50 sources of domestic and foreign literature sources were analyzed, from 2012 to 2022. A systematic literature search was performed using PubMed, eLibrary, and HAC databases. As a result of the analysis, it was found that currently physiotherapy methods are some of the main methods of complex treatment for periodontal diseases. It has been established that gum massage has an anti-inflammatory effect, is able to destroy microbial biofilm and restore microcirculatory homeostasis. The methods of various types of massage, their effect on periodontal tissues, negative and positive sides are considered. As a result of the analysis, it was found that the use of gum massage in periodontal diseases is pathogenetically justified. It is scientifically proven that the choice of massage method depends on the clinical situation. However, neither domestic nor foreign literature suggests a point of view on the preference of a certain massage method, which emphasizes the extreme relevance of further research.

description: Essential oils (EOs) extracted from medicinal plants gained interest in research due to their potential effectiveness as antimicrobial compounds that can substitute chemical drugs for treatment of different disease. This study aims to use Tetraclinis articulata EO to block the activity of the angiotensin converting enzyme 2 (ACE2) as a receptor for SARS-CoV-2, this infection is triggered by binding of the spike protein of the virus to ACE2, which is highly expressed in the heart and lungs. Barbary thuja (Tetraclinis articulata), is an aromatic species that is essentially confined to the western Mediterranean region. It plays an important socioeconomic role in North Africa; it constitutes a pasture land for livestock and provides products for domestic use, and it widely used in traditional medicine for its multiple therapeutic virtues. This study reveals that some natural compounds extracted from Tetraclinis articulata give the best molecular docking scores, compared to the co-crystallized inhibitor β-D-mannose of the enzyme ACE2, to Chloroquine, and Hydroxychloroquine antiviral drugs also involved in other mechanisms as inhibition of ACE2 cellular receptor. A set of tests: the druglikeness property test, ADME/T test, PASS & P450 site of metabolism prediction, pharmacophore mapping and Molecular dynamics, were performed to determine the safety and efficacy of these ligands. This study revealed for the first time that the components of Tetraclinis articulata essential oils can be used as potential inhibitors to the ACE2 receptor of SARS-CoV-2.

description: We present Floquet calculations of high harmonic generation (HHG) for the lowest two electronic states of the $\mbox{H}_2^+$ ion by strong continuous-wave laser fields. We solve the non-Hermitian matrix problem to get accurate solutions to the periodic time-dependent Schrödinger equation (TDSE) by applying a pseudospectral representation combined with a complex absorbing potential method. This represents an alternative approach to direct TDSE solutions to obtain the harmonic spectra for the ion. We compare our HHG rates for the lower and upper states of $\mbox{H}^{+}_{2}$, which correspond to the gerade and ungerade ground states in the field-free case, with previously obtained results in the literature. We show that the enhancement of the ionization rates at the critical internuclear separation $R_{c}\approx 8\,au$ plays some role in the appearance of very strong harmonic orders $n=5-11$ at $λ= 1064\,nm$ and $n=5-9$ at $λ= 800\,nm$ and intensity $I=10^{14}\,W/cm^{2}$.

description: Spectral differential imaging (SDI) is part of the observing strategy of current and on-going high-contrast imaging instruments on ground-based telescopes. Although it improves the star light rejection, SDI attenuates the signature of off-axis companions to the star, just like angular differential imaging (ADI). However, the attenuation due to SDI has the peculiarity of being dependent on the spectral properties of the companions. To date, no study has investigated these effects. Our team is addressing this problem based on data from a direct imaging survey of 16 stars combining the phase-mask coronagraph, the SDI and the ADI modes of VLT/NaCo. The objective of the survey is to search for cool (Teff<1000-1300 K) giant planets at separations of 5-10 AU orbiting young, nearby stars (<200 Myr, <25 pc). The data analysis did not yield any detections. As for the estimation of the sensitivity limits of SDI-processed images, we show that it requires a different analysis than that used in ADI-based surveys. Based on a method using the flux predictions of evolutionary models and avoiding the estimation of contrast, we determine directly the mass sensitivity limits of the survey for the ADI processing alone and with the combination of SDI and ADI. We show that SDI does not systematically improve the sensitivity due to the spectral properties and self-subtraction of point sources.

description: In gauge theories the presence of constraints can obstruct expressing the global Hilbert space as a tensor product of the Hilbert spaces corresponding to degrees of freedom localized in complementary regions. In algebraic terms, this is due to the presence of a center --- a set of operators which commute with all others --- in the gauge invariant operator algebra corresponding to finite region. A unique entropy can be assigned to algebras with center, giving place to a local entropy in lattice gauge theories. However, ambiguities arise on the correspondence between algebras and regions. In particular, it is always possible to choose (in many different ways) local algebras with trivial center, and hence a genuine entanglement entropy, for any region. These choices are in correspondence with maximal trees of links on the boundary, which can be interpreted as partial gauge fixings. This interpretation entails a gauge fixing dependence of the entanglement entropy. In the continuum limit however, ambiguities in the entropy are given by terms local on the boundary of the region, in such a way relative entropy and mutual information are finite, universal, and gauge independent quantities.

description: Trihalomethanes (THMs) are toxic disinfection by-products, formed in the reaction of chlorine with organic matter. This work aimed to study THM formation during a unique case study of managed aquifer recharge (MAR) with chlorinated desalinated seawater. THM formation was tested in the field, along a 3.0 m deep vadose zone gallery. Two small-scale experiments were conducted in the site, with untreated and with bromide spiked desalinated seawater. These were accompanied by a large-scale, ~1-month long operational MAR event. In the small-scale experiments, THM concentrations were shown to increase with bromide concentrations, with increasing dominance of the brominated species. Nevertheless, concentrations remained within the single µg/L range, which is an order of magnitude lower than drinking water regulations. Such low THM concentrations were also determined in the large-scale event. In both cases, THM formation occurred in the ponding water, without significant formation or degradation in the upper 3.0 m of the vadose zone. This study shows that MAR with chlorinated (<0.5 mg/L) desalinated seawater through sandy infiltration basins does not pose a threat to drinking water quality at this site.

description: The multicomponent approach allows to incorporate several functionalities into a single covalent organic framework (COF) and consequently allows the construction of bifunctional materials for cooperative catalysis. The well-defined structure of such multicomponent COFs is furthermore ideally suited for structure-activity relationship studies. We report a series of multicomponent COFs that contain acridine- and 2,2’-bipyridine linkers connected through 1,3,5-benzenetrialdehyde derivatives. The acridine motif is responsible for broad light absorption, while the bipyridine unit enables complexation of nickel catalysts. These features enable the usage of the framework materials as catalysts for light-mediated carbon−heteroatom cross-couplings. Variation of the node units shows that the catalytic activity correlates to the keto-enamine tautomer isomerism. This allows switching between high charge-carrier mobility and persistent, localized charge-separated species depending on the nodes, a tool to tailor the materials for specific reactions. Moreover, nickel-loaded COFs are recyclable and catalyze cross-couplings even using red light irradiation.
Implementing Software Project Control Centers: An Architectural View

description: Setting up effective and efficient mechanisms for controlling software and system development projects is still challenging in industrial practice. On the one hand, necessary prerequisites such as established development processes, understanding of cause-effect relationships on relevant indicators, and sufficient sustainability of measurement programs are often missing. On the other hand, there are more fundamental methodological deficits related to the controlling process itself and to appropriate tool support. Additional activities that would guarantee the usefulness, completeness, and precision of the result- ing controlling data are widely missing. This article presents a conceptual architecture for so-called Software Project Control Centers (SPCC) that addresses these challenges. The architecture includes mechanisms for getting sufficiently precise and complete data and supporting the information needs of different stakeholders. In addition, an implementation of this architecture, the so-called Specula Project Support Environment, is sketched, and results from evaluating this implementation in industrial settings are presented.

Pudeur et splendeur de la prostitution chez Aimé Césaire et Zadi Zaourou
Creators: name: Dorgelès, Houessou
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2018

description:

In the Cahier d’un retour au pays natal, Césaire depicts prostitution in its abject and reprehensible dimension. Many stylistic processes, such as the reference to the biblical account of the fall, thus define a servile and shameful practice. The reason is that the poet subtly encodes the vice of the sex trade that he makes the equivalent of cultural assimilation. In contrast, Zadi Zaourou Bernard, Ivorian poet and disciple of Césaire, generally depicted prostitution under the aegis of admiration. Elegy for those bodies offered to the libidinal satisfaction of whoever is able to pay the price, some poems from his collection titled À Califourchon sur le dos d’un nuage raise and sublimate the prostitute.

De la dépossession à l’expérience de la possession dans Meursault, contre-enquête de Kamel Daoud

Year: 2018

description:

There is a clear correlation between the text of L'Étranger of Camus and Meursault, contre-enquête of Kamel Daoud, fertility is sure. Daoud, living in a previously colonised minority context, manipulates Camus’ memorised coded speech to make himself heard. Is it a confrontation or a duplication of speech? The writing attempts to find points of instability and mobility likely to ruin the ‘temple’ of a monumental literary building. Emphasis will be placed on this gesture of appropriation and the polyphony of the text sited between recovery and transgression. This play of intertextuality creates a discursiveness that destabilizes the reader. The reading follows a retroactive investigation that goes beyond an experience of negativity by traversing a path between myth and fantasy that visualises a peaceful relationship between East and West.

title: Measuring acoustic ice properties for the Enceladus Explorer

description: The Enceladus Explorer initiative is a feasibility study for a lander mission to Saturn's moon Enceladus with the goal to search for extraterrestrial life. Enceladus is covered in ice and possesses a salt water ocean around its core, which could provide acceptable conditions for the development of alien bacteria. Through four giant crevasses at Enceladus south polar region some of that water is transported to the surface where it is ejected through about 100 plumes. The idea of the Enceladus Explorer project is to land next to one of these crevasses and deploy an automated steerable melt down probe. That probe is then supposed to melt itself deep enough into the ice to find the water-bearing part of the crevasse, take a sample of the liquid and do an in-situ microbiological analysis. To achieve that goal, the probe is in need of a suitable positioning system. One option for such a positioning system is an acoustic positioning system (APS). The main operating principle of that APS is based on trilateration. Several transducers are deployed at known locations distributed over the surface of the site and the probe is eqipped with some receivers. By measuring the signal propagation times between each transducer and the probe it is possible to calculate the distances between each transducer and the probe from the known speed of sound in the surrounding ice and then, from these distances, the position of the probe itself. The accuracy of this is method is limited by the precision of the time measurement and the understanding of possible variations of the speed of sound. In addition the range of the acoustic signals sets a limit to the range of the APS. The efforts taken to improve the understanding of the properties of the ice and the development of a method to extract the arrival time from the recorded waveforms are the main focus of this thesis.
