description: To determine whether a number is congruent or not is an old and difficult topic and progress is slow. The paper presents a new theorem when a prime number is a congruent number or not. The proof is not necessarily any simpler or shorter than existing proofs, but the method may be useful in other contexts. The proof of Theorem 1 tracks the set of solutions and this set branches as a binary tree. Conditions set to the theorem restricts the branches so that only one branch is left. Following this branch gives either a solution or a contradiction. In Theorem 1 it leads to a contradiction. The interest is in the proof method, which maybe can be generalized to non-primes.

description: We present first results of a mixed action project. We analyze gauge configurations generated with two flavors of dynamical twisted mass fermions. Neuberger's overlap Dirac operator is used for the valence sector. The various choices in the setup of the simulation are discussed. We employ chiral perturbation theory to describe the effects of using different actions in the sea and valence sector at non-zero lattice spacing.

Analyse Comparative Des Revenus Des Menages, Avant Et Apres Confinement Dans La Ville De Goma/ R.D. Congo

description: We approached this study with the perspective that the lockdown decided by the national and provincial authorities led to an unpredictable halt to all socio-economic activities. This research focused specifically on the questions of knowing the impact of the lockdown due to the COVID-19 pandemic on the socio-economic life of households in the city of Goma; and how can we judge the economic and financial situation of different households before and after lockdown in the city of Goma.

Indeed, to respond to these different concerns in advance, the following hypotheses were put forward: The lockdown has a negative impact on the socio-economic situation of different households in the city of Goma; and that before the lockdown, households were somewhat stable compared to the implementation of the lockdown; the situation had worsened during and after with an exaggerated increase in prices and the scarcity of goods and services on the markets.

Our overall objective is to analyze household income before and after the lockdown due to the COVID-19 pandemic in the city of Goma; and particularly to know the effect of this confinement on the economic situation of the different households in the city of Goma and then determine the income of households before and after confinement.

To develop this article, we used analytical, comparative, statistical methods, supported by documentary techniques, questionnaire, direct observation and interview.

Our hypotheses were to show and/or verify that the Covid-19 pandemic was a real scourge in the DRC, given that it destroyed the socio-economic fabric of all sectors of life through the practice of confinement. In fact, the latter had a negative impact on the socio-economic situation of different households in the city of Goma. Moreover, we can assume that before the confinement, households were somewhat stable, the situation had worsened during and after with an exaggerated increase in the price on the market for goods and services. Finally, it was also a question of looking for the consequences caused by the confinement due to the Covid-19 pandemic based on the following indicators: poverty, degradation of morals (prostitution, theft, etc.).

description: In this repository it is possible to download the matlab routines required to perform the computational steps according to the mechanical model described in the paper 'Extended tension chord model for boundary elements of RC walls accounting for anchorage slip and lap splices presence'. This paper presents a mechanical model for the simulation of reinforced concrete (RC) wall boundary elements with lap splices, which builds on the tension chord model. The model is composed of an assembly of components, each one accounting for a different source of deformation. Namely: (i) an anchorage-slip element accounting for the strain penetration of the longitudinal reinforcement into the foundation; (ii) a basic tension chord element evaluating the response outside the lap splice zone; and (iii) a lap splice element describing the behaviour within the lap splice region. For an imposed global displacement, the model provides the steel and concrete stress and strain distributions, the crack distribution and opening, as well as the global resisting axial force. For spliced members, the ultimate displacement is computed through a semi-empirical relationship providing the average lap splice strain at failure. Validation is carried out against a series of uniaxial cyclic tests on RC wall boundary elements featuring both continuous and spliced reinforcement; different lap splice lengths and confining reinforcement are considered.

description: We investigate the dynamics of an epidemiological susceptible-infected-susceptible (SIS) model on an adaptive network. This model combines epidemic spreading (dynamics on the network) with rewiring of network connections (topological evolution of the network). We propose and implement a computational approach that enables us to study the dynamics of the network directly on an emergent, coarse-grained level. The approach sidesteps the derivation of closed low-dimensional approximations. Our investigations reveal that global coupling, which enters through the awareness of the population to the disease, can result in robust large-amplitude oscillations of the state and topology of the network.

description: The evolution of magnetic properties of isostructural and isoelectronic solid solutions of the superconducting itinerant 5f-electron ferromagnet UCoGe with antiferromagnet UIrGe was studied by magnetization, AC susceptibility, specific heat, and electrical resistivity measurements of a series of UCo1-xIrxGe compounds in polycrystalline and single crystalline form at various temperatures and magnetic fields. Both the weak ferromagnetism and superconductivity in UCoGe were found to have vanished already for very low Ir substitution for Co x = 0.02. The antiferromagnetism of UIrGe is gradually suppressed. This is documented by a rapid decrease in both Neel temperature and the critical field of the metamagnetic transition with decreasing Ir concentration, which both tend to vanish just above x = 0.8. The section of the T-x phase diagram in the range x between 0.02 and 0.8 is dominated by a correlated paramagnetic phase exhibiting very broad bumps in temperature dependencies of b-axis magnetization and specific heat developing with increasing x. For x = 0.24, wide peaks appear in the c-axis thermomagnetic curves due to antiferromagnetic correlations which may eventually lead to frozen incoherent spin configurations at low temperatures. The correlated paramagnetic phase is also accompanied by specific electrical resistivity anomalies. The T-x phase diagram determined for the UCo1-xIrxGe compounds contrasts with the behavior of the related URh1-xIrxGe system, which was reported to exhibit an extended concentration range of stable ferromagnetism in Rh rich compounds and a discontinuous transformation between the ferromagnetic and antiferromagnetic phases at a critical Rh-Ir concentration.

Cointegration and stationarity analysis of Japanese speculative land and stock markets: 1982-1993

description: There was a remarkable downturn in the stock and land markets of Japan at the end of 1989 and the beginning of 1990. This thesis examines speculative stock and land market indices, explores relationships between these indices, and determines if the downturn had any affect on such relationships. The two sets of data used are measures of the Japanese speculative stock market (the Nikkei and Topix, Tokyo Stock Exchange market indices) and measures of the Japanese speculative land market (golf course membership price indices for the country as a whole, the eastern part of Japan, the western part of Japan, and Tokyo). Preliminary analysis of the data suggests the existence of three similarities: first, between the two stock market indices; second, amongst the four golf course membership price indices; and, third, between the set of stock market indices and the set of golf course membership price indices. The graphs of the data, the effects of transformations, the lack of outliers, the lack of seasonality, and the distributions of the data are remarkably alike. However, a more technical look at the data supports the opposing point of view. ARIMA modelling shows there exists surprisingly little structural similarity either within or between the two sets of data (i.e., the speculative stock and land market indices). In addition, cointegration test results provide little evidence of the expected relationship between these data sets. When accounting for the effect of the downturn on the data, evidence of linear relationships does exist. Cointegration tests using data before the downturn provide evidence of linear relationships between the two data sets (particularly between the stock market indices and the country composite index for golf course membership prices). However, examination of data from after the downturn shows that the downturn seems to have changed the data in such a way as to remove these previously existing linear relationships between the two sets of indices. Cointegration tests show no linear relationships appear to exist within either data set before the downturn (i.e., between the two stock market indices or between any pairwise combination of the four golf course membership price indices), but there is evidence of some such relationships after the downturn. The conclusion of this paper is that the downturn actually changed the relationships within each set of data (i.e., between different measures of the speculative stock market and between different measures of the speculative land market) and between the two sets of data (i.e., the relationship between the Japanese stock and land markets).

description: The increasing rates of early sexual involvement among adolescents are a significant global public health concern. Despite widespread awareness of the risks associated with early sexual activity, adolescents are becoming sexually active at younger ages. The extent of this issue within the Oruchinga Refugee Settlement is unclear, making it essential to understand the factors contributing to early sexual involvement in this community. Identifying these factors will aid in developing targeted prevention strategies and policies to encourage adolescents to delay sexual activity until marriage, thereby improving their reproductive health. This study aims to explore the factors associated with early sexual behavior among adolescents in the Oruchinga Refugee Settlement in Isingiro district.

description: We discuss three families of groups, $ZW_n$, $PL(I^n)$, and $PL(S^n)$ (the last two being families of groups of piecewise-linear homeomorphisms of standard $n$-dimensional spaces). We note that for all positive integers $n$, $ZW_n$ embeds in $PL(I^n)$ which embeds in $PL(S^n)$. In another direction, $ZW_2$ fails to embed in $PL(I^1)$ by an earlier result of the author, and we extend that result to show that $ZW_2$ also fails to embed in $PL(S^1)$. The nature of the proofs of these non-embedding results leads us to ask if there are corresponding non-embedding results in higher dimensions.

description: Abiraterone and enzalutamide, androgen receptor pathway inhibitors (ARPI) for the treatment of metastatic castration-resistant prostate cancer (mCRPC), are at high risk of potential drug interactions (PDIs). We aimed to describe PDIs and their management, and triggered adverse events (AEs) in clinical practice. We conducted a cross-sectional study in mCRPC patients who started treatment with abiraterone or enzalutamide in a university hospital between August 1st, 2016 and July 31st, 2020. Lexicomp® was used to identify and analyze PDIs, and the clinical records to assess their management and the occurrence of AEs. We included 173 patients: 36.8% and 93.0% treated with abiraterone and enzalutamide, respectively, had at least 1 PDI. Globally, 6.3% of PDIs had X-risk (contraindication due to high probability of AE). Treatment was modified in 9.2% of patients and 9.8% suffered AEs due to PDIs. Factors associated with a higher risk of PDIs were polypharmacy (OR= 41.0, p 0.003) and treatment with enzalutamide (OR= 128.26, p At least two-thirds of patients treated with ARPI suffered a PDI. Overall, abiraterone would have a more favorable PDI profile. Knowing these interaction profiles may be helpful to develop a more efficient therapeutic follow-up and to select the safest treatment.

description: The static and dynamic local spin susceptibility of the organic Mott insulator $κ$-(ET)$_2$Cu$_2$(CN)$_3$, a model material of the spin- 1/2 triangular lattice, is studied by $^{13}$C NMR spectroscopy from room temperature down to 20 mK. We observe an anomalous field-dependent spectral broadening with the continuous and bipolar shift distribution, appearing without the critical spin fluctuations. It is attributable to spatially nonuniform magnetizations induced in the spin liquid under magnetic fields. The amplitude of the magnetization levels off below 1 K, while the low-lying spin fluctuations survive toward the ground state, as indicated by the temperature profile of the relaxation rates.

description: Non-commutative structures were introduced, independently and around the same time, in mathematical and in condensed matter physics (see Table~1). Souriau's construction applied to the two-parameter central extension of the planar Galilei group leads to the ``exotic'' particle, which has non-commuting position coordinates. A Berry-phase argument applied to the Bloch electron yields in turn a semiclassical model that has been used to explain the anomalous/spin/optical Hall effects. The non-commutative parameter is momentum-dependent in this case, and can take the form of a monopole in momentum space.

description: The aim of the present thesis was the study of the institution of commercial agent's compensation, which is regulated in the article 9 of the Presidential Decree 219/1991 about commercial agents, that was published in compliance with the Council Directive 86/653/EEC of 18 December 1986 on the coordination of the laws of the Member States relating to self-employed commercial agents. Especially, we analyzed the conditions under which the entitlement to indemnity arises and the conditions of the loss of the commercial agent's indemnity and, also, the way of the actual calculation of the amount of this indemnity. Then we presented some procedural issues referring to the entitlement of the indemnity. Furthermore, in the light of the regulation of the law 3557/2007 (article 14 par. 4, b') and the recent legal precedent, we examined the matter of the applicability of the article 9 of the p.d. 219/1991 to commission contracts, distributorship contracts and franchise agreements.

description: Treatment-related neurotoxicity is a common side effect in cancer patients. However, few data are available regarding the risk of several neurotoxicities in patients treated with immune checkpoint inhibitors. The MOUSEION-02 study is an up-to-date meta-analysis aimed at assessing the risk of peripheral neuropathy, peripheral sensory neuropathy, and headache in cancer patients receiving immunotherapy and immuno-oncology combinations. Patients receiving immunotherapy (as monotherapy or in combination with other anticancer agents) showed lower risk of all-grade peripheral neuropathy (RR, 0.50; 95% CI, 0.35–0.70) and all-grade peripheral sensory neuropathy (RR, 0.49; 95% CI, 0.30–0.79). Similarly, in patients treated with immune checkpoint inhibitor monotherapy, we observed lower risk of all-grade peripheral neuropathy (RR, 0.05; 95% CI, 0.03–0.10) and all-grade peripheral sensory neuropathy (RR, 0.11; 95% CI, 0.05–0.23). No differences were observed in terms of all-grade headache. Although the results of this meta-analysis should be interpreted with caution due to several issues, our study draws attention to immunotherapy-related neurotoxicity with the aim of maximizing clinical outcomes of cancer patients experiencing these not uncommon, and yet poorly studied, adverse events.

description: For an atomic condensate in an axially symmetric magnetic trap, the sum of the axial components of the orbital angular momentum and the hyperfine spin is conserved. Inside an Ioffe-Pritchard trap (IPT) whose magnetic field (B-field) is not axially symmetric, the difference of the two becomes surprisingly conserved. In this paper we investigate the relationship between the values of the sum/difference angular momentums for an atomic condensate inside a magnetic trap and the associated gauge potential induced by the adiabatic approximation. Our result provides significant new insight into the vorticity of magnetically trapped atomic quantum gases.

description: We revisit the 4D generalized black hole geometries, obtained by us [1], with a renewed interest, to unfold some aspects of effective gravity in a noncommutative D3-brane formalism. In particular, we argue for the existence of extra dimensions in the gravity decoupling limit in the theory. We show that the theory is rather described by an ordinary geometry and is governed by an effective string theory in 5D. The extremal black hole geometry $AdS_5$ obtained in effective string theory is shown to be in precise agreement with the gravity dual proposed for D3-brane in a constant magnetic field. Kaluza-Klein compactification is performed to obtain the corresponding charged black hole geometries in 4D. Interestingly, they are shown to be governed by the extremal black hole geometries known in string theory. The attractor mechanism is exploited in effective string theory underlying a noncommutative D3-brane and the macroscopic entropy of a charged black hole is computed. We show that the generalized black hole geometries in a noncommutative D3-brane theory are precisely identical to the extremal black holes known in 4D effective string theory.

description: Breast cancer is the most overspread cancer in
 women worldwide, with around 1.7 million new cases every
 year. Multidisciplinary clinical teams or committees, usually
 known as Breast Units (BU), are heterogeneous teams
 composed by all clinical specialist involved in the care of a
 breast cancer patient (e.g. oncologist, surgeon, …) that aim to
 discuss these complex clinical cases from all points of view and
 in the shortest time to provide best health care. BUs base their
 decisions on the Clinical Practice Guidelines (CPGs),
 documents that summarize the latest and best evidence-based
 medicine. Nevertheless, these documents have some knowledge
 lacks that make them insufficient when working with complex
 cases “out of the rule”, that may represent the 10-20% of the
 cases. To cope with this pitfall, DESIREE proposes a unified
 ecosystem that manages all the relevant information of the
 patients and provides support to clinicians when making a
 clinical decision in a personalized, collaborative and
 multidisciplinary way. It is composed by three main
 components: (i) an image-based breast and tumor
 characterization tool, (ii) a predictive model after breast
 conservative therapy and radio-biological model, and (iii) three
 different clinical decision support systems (i.e. guideline-based,
 experience-based and patient similarity based) that coexist and
 complement each other to give most personalized and best
 evidence-based recommendations to the BUs. All these are
 supported by DESIMS (i.e. DESiree Information Management
 System), a Security and Access Control module and an image
 system for image and models visualization.

description: The objective of the present thesis is the meta-analysis of all dissertations and their attributes that have been completed up to and including the start of 2012, within the Joint Postgraduate Course “Informatics and Management” via qualitative and quantitative content analysis, in order to study the attributes and trends of the course. This thesis encompasses extensive research for the identification and gathering of the aforementioned theses and dissertations as well as their organization in an electronic database. Furthermore, certain important characteristics of the theses have been subject to classification and statistical analysis, in search of correlations, focusing on the time required to complete each thesis, on their scientific discipline as well as on the categories in which they are organized. In addition, the study focuses on the subject of interdisciplinary theses and whether a blending between the two different disciplines has occurred over the years of the course. This study constitutes the basis for the development of a methodology of assessment of the operation of the course, primarily referring to the theses that are completed, which constitute the cornerstone of each level of studentship in an academic environment.

Στα σφαιρίδια αυτά έγινε ενθυλάκωση των φαρμακευτικών ουσιών ρισπεριδόνης και octreotide με σκοπό την ελεγχόμενη αποδέσμευση των ουσιών από τη μήτρα των βιοδιασπώμενων πολυμερών.Τα παρασκευασθέντα δείγματα πέρασαν από μια σειρά μεθόδων για τον προσδιορισμό των φυσικοχημικών χαρακτηριστικών τους. Μεγαλύτερη έμφαση δόθηκε στη μελέτη της μορφολογίας τους με τη χρήση SEM, ενώ για το σετ δοκιμών με το πολυμερές PDLG 7507 πραγματοποιήθηκαν και μετρήσεις με FT-IR, DSC, XRD. Η μελέτη του ρυθμού αποδέσμευσης έγινε σε συσκευές in vitro διαλυτοποίησης και η εξαγωγή των αποτελεσμάτων πραγματοποιήθηκε με την χρήση υγρής χρωματογραφίας υψηλής πίεσης (ΗPLC). Σύμφωνα με τα αποτελέσματα, στα συστήματα με PDLG 7507 επιτεύχθηκε η πλήρης αμορφοποίηση της δραστικής ένωσης σε χαμηλές συγκεντρώσεις της, ενώ όσο αυξάνεται η συγκέντρωση της δραστικής αυξάνεται και η κρυσταλλικότητα στα δείγματα. Αντίστοιχα, στις δοκιμές με PDLG 5004A, όπως και στις δοκιμές που πραγματοποιήθηκαν με τεχνική ξήρανσης με ψεκασμό, προσδιορίστηκαν ειδικές συνθήκες και αναλογίες ώστε να επιτευχθεί η παρασκευή μικροσωματιδίων στα ζητούμενα μεγέθη.
description: The aim of the present thesis was the study of PLGA and PLA systems, that were used to manufacture microspheres by the techniques of o/w solvent evaporation and spray drying. The microspheres were encapsulated with the pharmacological substances of risperidone and octreotide aiming for their controlled release from the biodegradable polymer matrix. The samples were tested by a series of methods in order to define their physicochemical properties. Greater emphasis was given to the study of morphology with the use of SEM, while the set of tests with the polymer PDLG 7507 were also tested with FTIR, DSC, XRD. The drug release study was done in vitro with dissolution devices and the results were taken with the use of the HPLC technique. According to the results, in the PDLG 7507 systems the drastic compound was dissolved in amorphous state for low drug concentration, whereas with the increase of the compound concentration there is an increase in the crystallinity of the sample. As well as in the tests done with PDLG 5004A, as well as the tests with spray drying, we were able to define the specific circumstances and percentages in order to manufacture microspheres of the required sizes.

On the origin dependence of multipole moments in electromagnetism

description: The standard description of material media in electromagnetism is based on multipoles. It is well known that these moments depend on the point of reference chosen, except for the lowest order. It is shown that this "origin dependence" is not unphysical as has been claimed in the literature but forms only part of the effect of moving the point of reference. When also the complementary part is taken into account then different points of reference lead to different but equivalent descriptions of the same physical reality. This is shown at the microscopic as well as at the macroscopic level. A similar interpretation is valid regarding the "origin dependence" of the reflection coefficients for reflection on a semi infinite medium. We show that the "transformation theory" which has been proposed to remedy this situation (and which is thus not needed) is unphysical since the transformation considered does not leave the boundary conditions invariant.

description: Data science has employed great research efforts in developing advanced analytics, improving data models and cultivating new algorithms. However, not many authors have come across the organizational and socio-technical challenges that arise when executing a data science project: lack of vision and clear objectives, a biased emphasis on technical issues, a low level of maturity for ad-hoc projects and the ambiguity of roles in data science are among these challenges. Few methodologies have been proposed on the literature that tackle these type of challenges, some of them date back to the mid-1990, and consequently they are not updated to the current paradigm and the latest developments in big data and machine learning technologies. In addition, fewer methodologies offer a complete guideline across team, project and data & information management. In this article we would like to explore the necessity of developing a more holistic approach for carrying out data science projects. We first review methodologies that have been presented on the literature to work on data science projects and classify them according to the their focus: project, team, data and information management. Finally, we propose a conceptual framework containing general characteristics that a methodology for managing data science projects with a holistic point of view should have. This framework can be used by other researchers as a roadmap for the design of new data science methodologies or the updating of existing ones.

"An act respecting sexual sterilization" : reasons for enacting and repealing the act
Creators: name: Heeswijk, Gail Van
Publisher: name: University of British Columbia
Year: 2009

description: British Columbia enacted "An Act Respecting Sexual Sterilization" on April 1, 1933 and repealed the Act on April 18, 1973. Through historical research, this thesis investigates the reasons for both the enactment and repeal of the Act. Also, the thesis describes the changing status of surgical sterilization during those years. Surgical sterilization initially began as a form of genetic selection for those in institutions. By the 1940s there was demand from the public that this procedure be available. It was not until the 1960s that voluntary surgical sterilization became available, but not without much debate as to whether the procedure was legal outside of the Act. By the 1970s, voluntary sterilization was accessible. The Act was repealed during this time as the understanding of heredity had changed and it appeared that the Act was used to solve behavioral problems rather than problems of heredity.

description: Electric field enhanced electron spin coherence is characterized using time-resolved Faraday rotation spectroscopy in n-type ZnO epilayers grown by molecular beam epitaxy. An in-plane dc electric field E almost doubles the transverse spin lifetime at 20 K, without affecting the effective g-factor. This effect persists till high temperatures, but decreases with increasing carrier concentration. Comparisons of the variations in the spin lifetime, the carrier recombination lifetime and photoluminescence lifetimes indicate that the applied E enhances the radiative recombination rate. All observed effects are independent of crystal directionality and are performed at low magnetic fields (B < 0.2 T).

description: We consider simultaneous explanations of the electron and muon $g-2$ anomalies through a single $Z'$ of a $U(1)'$ extension to the Standard Model (SM). We first perform a model-independent analysis of the viable flavour-dependent $Z'$ couplings to leptons, which are subject to various strict experimental constraints. We show that only a narrow region of parameter space with an MeV-scale $Z'$ can account for the two anomalies. Following the conclusions of this analysis, we then explore the ability of different classes of $Z'$ models to realise these couplings, including the SM$+U(1)'$, the $N$-Higgs Doublet Model$+U(1)'$, and a Froggatt-Nielsen style scenario. In each case, the necessary combination of couplings cannot be obtained, owing to additional relations between the $Z'$ couplings to charged leptons and neutrinos induced by the gauge structure, and to the stringency of neutrino scattering bounds. Hence, we conclude that no $U(1)'$ extension can resolve both anomalies unless other new fields are also introduced. While most of our study assumes the Caesium $(g-2)_e$ measurement, our findings in fact also hold in the case of the Rubidium measurement, despite the tension between the two.

description: Let $C$ be a curve of genus two. We denote by $SU_C(3)$ the moduli space of semi-stable vector bundles of rank 3 and trivial determinant over $C$, and by $J^d$ the variety of line bundles of degree $d$ on $C$. In particular, $J^1$ has a canonical theta divisor $Θ$. The space $SU_C(3)$ is a double cover of $P^8=|3Θ|$ branched along a sextic hypersurface, the Coble sextic. In the dual $\check{P}^8=|3Θ|^*$, where $J^1$ is embedded, there is a unique cubic hypersurface singular along $J^1$, the Coble cubic. We prove that these two hypersurfaces are dual, inducing a non-abelian Torelli result. Moreover, by looking at some special linear sections of these hypersurfaces, we can observe and reinterpret some classical results of algebraic geometry in a context of vector bundles: the duality of the Segre-Igusa quartic with the Segre cubic, the symmetric configuration of 15 lines and 15 points, the Weddle quartic surface and the Kummer surface.

description: Primordial black holes (PBHs) produced in the early Universe have attracted wide interest for their ability to constitute dark matter and explain the compact binary coalescence. We propose a new mechanism of PBH production during first-order phase transitions (PTs) and find that PBHs are naturally produced during PTs model-independently. Because of the randomness of the quantum tunneling, there always exists some probability that the vacuum decay is postponed in a whole Hubble volume. Since the vacuum energy density remains constant while radiation is quickly redshifted in the expanding Universe, the postponed vacuum decay then results in overdense regions, which finally collapse into PBHs as indicated by numerical simulations. Utilizing this result one can obtain mutual predictions and constraints between PBHs and GWs from PTs. The predicted mass function of PBHs is nearly monochromatic. We investigate two typical cases and find that 1) PBHs from a PT constitute all dark matter and GWs peak at $1$Hz, 2) PBHs from a PT can explain the coalescence events observed by LIGO-Virgo collaboration, and meanwhile GWs can explain the common-spectrum process detected by NANOGrav collaboration.

description: We present an investigation of the phase diagram of cholesteric liquid crystals within the framework of Landau - de Gennes theory. The free energy is modified to incorporate all three Frank elastic constants and to allow for a temperature dependent pitch in the cholesteric phase. It is found that the region of stability of the cubic blue phases depends significantly on the value of the elastic constants, being reduced when the bend elastic constant is larger than splay and when twist is smaller than the other two. Most dramatically we find a large increase in the region of stability of blue phase I, and a qualitative change in the phase diagram, in a system where the cholesteric phase displays helix inversion.

description: The research designs a new integrated system for the security enhancement of a decentralized network by preventing damages from attackers, particularly for the 51 percent attack. The concept of multiple layered design based on Blockchain Governance Games frameworks could handle multiple number of networks analytically. The Multi-Layered Blockchain Governance Game is an innovative analytical model to find the best strategies for executing a safety operation to protect whole multiple layered network systems from attackers. This research fully analyzes a complex network with the compact mathematical forms and theoretically tractable results for predicting the moment of a safety operation execution are fully obtained. Additionally, simulation results are demonstrated to obtain the optimal values of configuring parameters of a blockchain-based security network. The Matlab codes for the simulations are publicly available to help those whom are constructing an enhanced decentralized security network architecture through this proposed integrated theoretical framework.

Konsequenzen aus der Anrechnung von Gärresten pflanzlicher Herkunft auf die  N-Ausbringungsobergrenze organischer Düngemittel und auf die Derogation – Status quo und Empfehlungen

description: Eine deutschlandweite Analyse des regionalen Wirtschaftsdüngeranfalls offenbart, dass insbesondere Regionen in Nordwestdeutschland durch einen beachtlichen Wirtschaftsdüngeranfall sowohl tierischer als auch pflanzlicher Herkunft gekennzeichnet sind. Bisher mussten Gärreste pflanzlicher Herkunft aus der Biogasproduktion im Hinblick auf die Ausbringungsobergrenze von 170 Kilogramm Stickstoff pro Hektar nicht berücksichtigt werden.

Mit der anstehenden Novellierung der Düngeverordnung soll dies allerdings geändert werden. Eine dabei diskutierte Ausbringungsmenge bis zu 250 Kilogramm Stickstoff für Acker- und Grünlandflächen von Biogaserzeugern würde teilweise zu einer betriebswirtschaftlichen Entlastung der ansonsten zukünftig sich verändernden regionalen Nährstoffproblematik und dem damit verbundenen Flächenbedarf zur Wirtschaftsdüngerverbringung führen. Allerdings wäre eine derartig generelle Vorgehensweise aus ökologischer und pflanzenbau-technischer Sicht fragwürdig. Demgegenüber kann die Derogation für intensiv genutzte Grünlandflächen als wirksames und sinnvolles Instrument verstanden werden, das sowohl zur Entlastung der einzelbetrieblichen als auch der regionalen Stickstoff-Problematik beitragen kann, ohne dabei die Belange des Wasserschutzes außer Acht zu lassen.
