description: In this study, we propose that the signatures of spin fractionalization in quantum magnets can be identified through a detailed analysis of the temperature dependence of the asymmetric Fano lineshape of optical phonons overlapping with a continuum of spin excitations. We focus on the hyperhoneycomb magnet $β$-Li$_2$IrO$_3$, a promising candidate for being in proximity to a three-dimensional Kitaev quantum spin liquid. The Raman response in $β$-Li$_2$IrO$_3$ notably displays a distinctive asymmetric Fano lineshape in the 24 meV Raman-active optical phonon. This asymmetry arises from the interaction between the discrete phonon mode and the spin excitation continuum, which could be fractionalized if the material is indeed near a quantum spin-liquid phase. Our theoretical model considers the coupling of this optical phonon to Majorana fermions in the Kitaev model on the hyperhoneycomb lattice. Our findings reveal that the temperature-dependent Fano lineshape is consistent with the fractionalization of spins into Majorana fermions and $\mathbb{Z}{_2}$ fluxes.

description: The paper presents an analysis of the spatial structure of the Polish agriculture. Basing on the results of the Agricultural Census of 2010, six groups of internal factors in agriculture have been differentiated (land quality and land use; agrarian structure; socio-demographic factors; technical equipment; production structure; production and economical factors), which facilitated both the creation of the index of the general level of agriculture and the evaluation of the agricultural structure. The spatial matrices which evolved in the process were juxtaposed with the selected external factors in agriculture: natural, historical, urban and those related to the financial support available within the Common Agricultural Policy. It has been shown that the diverse spatial structure of agriculture is connected with natural factors to a small extent only; within the category of man-made factors, even if the European funds are well absorbed, historical determinants are the most significant.

description: More and more news organisations are implementing paywalls, as legacy revenues continue to erode and digital advertising increasingly go to large technology companies. In this Factsheet, we present an overview of the diffusion of different forms of pay models across a sample of 171 of the most important news organisations in six European countries (Finland, France, Germany, Italy, Poland, and the UK). Results show that different types of news organisations adopt diverse approaches. A clear majority of newspapers and weeklies operate a pay model (freemium, metered paywalls, hard paywalls), whereas all broadcasters and almost all digital-born sites offer free access to their news. Pay models adoption is widespread especially in Finland, France, and Poland, where from 87% to 95% of newspapers and weeklies have adopted paywalls. By contrast, in Italy, Germany and the UK, many of the most important news outlets continue to offer free access to their digital content.

description: Groats played an important role in traditional Polish cuisine. These products are also recommended by nutritionists today, and should appear in our diet. Research conducted in 2014 among residents of TriCity and surrounding areas has shown that consumers rarely eat groats. The most popular was buckwheat, barley and semolina (manna). It was found differences in the preferences of young people who are open to novelties and older who are traditionalists. Also sex marginally influenced the opinions of respondents. Consumers are aware of groats nutritional value and their importance in human nutrition.

Potentiality after the (f)act : the act between agency and love
Creators: name: Evans, Christine
Publisher: name: University of British Columbia
Year: 2010

description: In Lacanian psychoanalysis, the moment which designates the appearance of an authentic ethico-political Act is fraught with competing potentialities; because this Act materializes “as if” from nowhere, an Act’s conditions of appearance are often only available to us retroactively. Critics and philosophers such as Slavoj Žižek have attempted to account for these retroactive appearances in both culture and politics. While I acknowledge Žižek’s contribution to the Act’s contemporary recrudescence, certain problematic fissures in Žižek’s theorization of the Act nonetheless require address. Primarily, while Žižek conceives of the subject as necessary to the Act’s performance, he formulates the Act as either perpetually abstracted or entirely possible; this contentiously obliges the acting subject to vacillate between potentiality (the endless horizon of abstraction) and actualization (that space of free action in which he can effectively “change everything”). Using these Žižekian horizons of potentiality and actualization to guide my analysis, I attempt in this project to engineer a condition of possibility for the acting subject which simultaneously accounts for the Act’s miraculous materialization and the acting subject’s constitutive “subjection” to Otherness. In a series of structural transpositions, I explore the subject’s relationship with the Act apropos of aphanisis (subject self-erasure), Christian love, and the Benjaminian recapitulation of past revolutionary potential. I contend throughout that the creation of a horizon of possibility for the Act is contingent on our primary recognition of the acting agent’s relationship with the Act’s dual impulses of destruction and renewal.

description: We develop a new method to reconstruct the power spectrum of primordial curvature perturbations, $P(k)$, by using both the temperature and polarization spectra of the cosmic microwave background (CMB). We test this method using several mock primordial spectra having non-trivial features including the one with an oscillatory component, and find that the spectrum can be reconstructed with a few percent accuracy by an iterative procedure in an ideal situation in which there is no observational error in the CMB data. In particular, although the previous ``cosmic inversion'' method, which used only the temperature fluctuations, suffered from large numerical errors around some specific values of $k$ that correspond to nodes in a transfer function, these errors are found to disappear almost completely in the new method.

description: The XENON1T collaboration recently reported the excess of events from recoil electrons, possibly giving an insight into new area beyond the Standard Model (SM) of particle physics. We try to explain this excess by considering effective interactions between the sterile neutrinos and the SM particles. In this paper, we present an effective model based on one-particle-irreducible interaction vertices at low energies that are induced from the SM gauge symmetric four-fermion operators at high energies. The effective interaction strength is constrained by the SM precision measurements, astrophysical and cosmological observations. We introduce a novel effective electromagnetic interaction between sterile neutrinos and SM neutrinos, which can successfully explain the XENON1T event rate through inelastic scattering of the sterile neutrino dark matter from Xenon electrons. We find that sterile neutrinos with masses around $90$ keV and specific effective coupling can fit well with the XENON1T data where the best fit points preserving DM constraints and possibly describe the anomalies in other experiments.

description: In der vorliegenden Arbeit werden weltweit übliche Abbruchkriterien bei Felsinjektionen vergleichend analysiert. Unter Felsinjektionen versteht man das Einpressen eines Injektionsmittels in Felsklüfte. Abbruchkriterien sind dabei Bedingungen, die erfüllt sein müssen, damit das Injektionsziel als erreicht gilt und die Injektion beendet werden kann. Während der Injektion stehen für die Beurteilung lediglich der Injektionsdruck am Bohrlochmund und die Durchflussrate an der Injektionspumpe zur Verfügung. Auf Grundlage dieser gemessenen Parameter müssen die Abbruchkriterien erstellt werden. In der Praxis haben sich dazu bis heute verschiedene Methoden wie die Amenability Theory, die GIN-Methode, die ACG-Methode, die TPA-Methode, die PSG-Methode oder die RTGC-Methode etabliert. Die unterschiedlichen Methoden werden in dieser Arbeit hinsichtlich der zugrunde liegenden Theorie und der praktischen Anwendung analysiert und deren Voraussetzungen, Eingangsdaten, Abbruchkriterien sowie Vor- und Nachteile beschrieben. Es wird aufgezeigt, dass es mit den Ansätzen in den unterschiedlichen Methoden tatsächlich möglich ist, alleine durch Betrachtung des Injektionsdrucks und der Durchflussrate Aussagen über die Zustände im Kluftsystem zu treffen. In weiterer Folge werden die unterschiedlichen Methoden miteinander verglichen und auf Basis der Analyse beurteilt.
description: This thesis analyses common stop criteria in rock grouting. Grouting of rock is the process of injecting grout into jointed rock mass. Stop criteria are terms that need to be fulfilled in order to reach the aim of the grouting and to have the grouting measures completed. During grouting only the pressure at the top of the borehole and the flow rate at the injection pump can be used to evaluate the process. The stop criteria must be set up based on these two parameters. Until now different methods like the amenability theory, the GIN-method, the ACG-method, the TPA-method, the PSG-method or the RTGC-method have been developed. In this thesis the methods are analysed regarding the theory behind the method, its practical application, technical requirements, input data as well as the criteria for the stop itself. Different approaches in various common methods allow one to issue statements on the quality of the grouted fractures only by watching the pressure and the flow rate. Furthermore this thesis compares and assesses the common methods based on their advantages and disadvantages.

description: We present a new method for extracting excited states from a single two-point correlation function calculated on the lattice. Our method simply combines the correlation function evaluated at different time slices so as to ``subtract'' the leading exponential decay (ground state) and to give access to the first excited state. The method is applied to a quenched lattice study (volume = 24^3 x 64, beta = 6.2, 1/a = 2.55 GeV) of the first excited state of the nucleon using the local interpolating operator O = [uT C gamma5 d] u. The results are consistent with the identification of our extracted excited state with the Roper resonance N'(1440). The switching of the level ordering with respect to the negative-parity partner of the nucleon, N*(1535), is not seen at the simulated quark masses and, basing on crude extrapolations, is tentatively expected to occur close to the physical point.

description: The paper aims to determine the impact of direct payments on the value and structure of capital of farms. Our reasearch on individual farms (participating in the EU-FADN) in Silesian province (for years 2005- 2008) was carried out. Our studies indicated that the highest direct payments were received by owners of the largest farms, in terms of both area and economic size. Farmers who represented entities with highest levels of direct payments in the first three years of receiving these subsidies, showed less interest in support with external financing, because cash from direct payments became a stable source of equity. Direct payments played an important role in the structure of financing of agricultural holdings, because farmers allocated funds from direct payments mainly to operating and investing activities, thereby reducing interest in support with external sources.

Then we propose work distributions that are compatible with QFT and we show that they satisfy the first law of thermodynamics up to second moments. We also show how these distributions satisfy Crooks theorem and provide a fully non-perturbative thermodynamic analysis of spacetime localized unitary processes on a quantum field.

It is also shown that all possible twisted derived equivalences between arbitrary twisted K3 surfaces form a subgroup of the group of all orthogonal transformations of the cohomology of a K3 surface. The passage from twisted derived equivalences to an action on the cohomology is made possible by twisted Chern characters that will be introduced for arbitrary smooth projective varieties.

description: The aim of the study was to perform a comprehensive analysis of the poultry meat market before and after the integration of Poland into the European Union. The study was carried out based on data from the Central Statistical Office of Poland, the Institute of Agricultural and Food Economics, and FAO. During the 10 years after joining the European Union, Poland witnessed a considerable increase in the domestic production, consumption and export of poultry meat (by 104,700 t/year on average) compared to the 10- year period before the integration, when this figure was 68,000 t/year. The growing demand for poultry meat and the strong growth in the export of poultry meat favour the increase in domestic production and it is thought that this tendency will continue in the next years, which is confirmed by the findings of other poultry market analysis.

description: We consider double canard cycles including two canards in singularly perturbed planar systems with two canard points. Previous work studied the complex oscillations including relaxation oscillations and canard cycles in singularly perturbed planar systems with one-parameter layer equations, which have precisely one canard point, two jump points or one canard point and one jump point. Based on the normal form theory, blow-up technique and Melnikov theory, we investigate double canard cycles induced by two Hopf breaking mechanisms at two non-degenerate canard points. Finally, we apply the obtained results to a class of cubic Lienard equations with quadratic damping.

description: Scientific theories based on mathematical models are frequently used in sciences to reveal natural behaviour of systems and eventually to be able in predicting such behaviour once the system's parameters and relevant conditions are known and can be specified. The integration of accumulated theoretical as well as experimental knowledge allows us to present such a unifying theory underlying the equivalence between habit and habitat in population growth. While the focus of the initial development was derived from microorganisms, the theory is extended to other population types too. The biological interpretation of ‘inertia’ or ‘habit’-based processes is provided as a consequence of this theory, and its relationship to the population ‘resource utilization’ available in the ‘habitat’ is derived. This paper focuses on the link between the ‘resource utilization’, which is related to the ‘habitat’, and ‘biological inertia’, which is related to population ‘habit’. This link extends the context of population growth and predictive modelling of microorganisms.

description: Digital-born and legacy news media are competing to control the most central positions in the flow of online news. In this RISJ Factsheet, we examine how this competition unfolds during the French presidential election. We analyze a sample of 2.96 million news related tweets from a larger dataset of 43.5 million messages collected during the 2017 French elections.  We find that legacy media, most notably newspapers and broadcasters, figure very prominently in the political discussions on Twitter. Legacy media generated more than seven times as much activity and engagement as digital-born news media during the election.
Our results suggest that some newspapers and digital-born news media have much lower levels of engagement than their general audience reach, follower count, and their frequent tweeting would lead one to expect. According to our analysis audience attention and engagement is very unevenly distributed and it is not always proportional to the level of media activity.

description: We report the detection of Lyman-continuum (LyC) photons from a massive interacting system at $z=1.097$ in the Hubble Ultra Deep Field. The LyC detection is made in the far-ultraviolet F154W band of the UVIT telescope onboard AstroSat. Both JWST and HST imaging of the system reveal signs that it is a likely merger. In particular, high-resolution imaging in the JWST bands reveals an infrared luminous object within the system that is faint in the bluer HST bands. The ionized-gas kinematics from the MUSE-UDF data supports the merger hypothesis. We estimate that the entire system is leaking more than $8 \%$ of its ionizing photons to the intergalactic medium. The SED-derived stellar masses of the two components indicate that this is a major merger with a mass ratio of ${1.13 \pm 0.37}$. This detection hints at the potential contribution of massive interacting systems at higher redshifts, when major mergers were more frequent, to the ionizing budget of the universe.

description: We consider self-avoiding polymers attached to the tip of an impenetrable probe. The scaling exponents $γ_1$ and $γ_2$, characterizing the number of configurations for the attachment of the polymer by one end, or at its midpoint, vary continuously with the tip's angle. These apex exponents are calculated analytically by $ε$-expansion, and numerically by simulations in three dimensions. We find that when the polymer can move through the attachment point, it typically slides to one end; the apex exponents quantify the entropic barrier to threading the eye of the probe.

description: In the twentieth century. Rural areas in Poland twice underwent system transformation, which led to the interruption of natural path of their development. The necessity was the choice of a new development model, which became sustainable development. However, this requires the development of innovative activities, while innovation should serve the sustainability of the system. This issue has become the subject of this study. This article attempts to answer the question whether assimilated innovations in rural areas conducive to sustainable development, or rather served to enhance the productivity of factors of production? The literature studies and the empirical studies lead to the conclusion that the current, the specificity of relationships with the surrounding rural areas makes, that innovation served mainly increase in productivity and did not serve sustainable development.

Extraction of the mass of the top quark by kinematic reconstruction is not possible because the event is under-constrained. We therefore employ a dynamical likelihood method to solve the problem.

Without active stabilization, we measure a root-mean-square (RMS) tilt variation of \SI{270}{\upmu rad} over three days. The active stabilization can be used to limit the tilt to \SI{0.35}{\upmu rad} RMS over the same time period. This technique can be used to minimize drift in tilt-sensitive experiments.

Do resources matter? : the cross cultural effect of gender ideology on the relationship between resources and marital power
Creators: name: Gozjolko, Kristi Lynne
Publisher: name: University of British Columbia
Year: 2010

description: In most investigations of marital power the focus of the study is on an individual’s characteristics within the relationship with little consideration of the effect of the social context in which the relationship exists. This investigation not only tests the individual’s characteristics but also uses country context as a moderator. This study investigates the relationship between resources and marital power and the moderating effect of gender ideology as the country context. Using the 2002 International Social Survey Programme (ISSP) Family and Changing Gender Roles Module I11 data set allows a cross cultural comparative investigation to occur. From the ISSP 2002 one country is chosen to represent each context, egalitarian (Sweden), traditional (Philippines) and transitional (United States). Using multinomial logistic regression it is found that the resources of relative education and relative income do not directly increase the participant’s power but rather, depending on the gender of the respondent, resource contribution is found to increase or decrease the partner’s power. Country context did not moderate the relationship between relative resources and marital power as expected. This investigation does not necessarily suggest that cultural context does not matter to marital power but simply indicates that more research is needed. Future cross national comparative research could include more countries in the analysis to have a greater understanding of the relationship between resources and marital power across countries.

description: Redondoviridae is a recently discovered DNA virus family consisting of two species, vientovirus and brisavirus. Here we used PCR amplification and sequencing to characterize redondoviruses in nasal/throat swabs collected longitudinally from a cohort of 58 individuals working with animals in Vietnam. We additionally analyzed samples from animals to which redondovirus DNA-positive participants were exposed. Redondoviruses were detected in approximately 60% of study participants, including 33% (30/91) of samples collected during episodes of acute respiratory disease and in 50% (29/58) of baseline samples (with no respiratory symptoms). Vientovirus (73%; 24/33) was detected more frequently in samples than brisaviruses (27%; 9/33). In the 23 participants with at least 2 redondovirus-positive samples among their longitudinal samples, 10 (43.5%) had identical redondovirus replication-gene sequences detected (sampling duration: 35–132 days). We found no identical redondovirus replication genes in samples from different participants, and no redondoviruses were detected in 53 pooled nasal/throat swabs collected from domestic animals. Phylogenetic analysis described no large-scale geographical clustering between viruses from Vietnam, the US, Spain, and China, indicating that redondoviruses are highly genetically diverse and have a wide geographical distribution. Collectively, our study provides novel insights into the Redondoviridae family in humans, describing a high prevalence, potentially associated with chronic shedding in the respiratory tract with lack of evidence of zoonotic transmission from close animal contacts. The tropism and potential pathogenicity of this viral family remain to be determined.

description: For almost forty years, from the decade of the sixties up to the present, many new schools, theories, currents and thoughts have been incorporated into the agribusiness management world, all these established by different authors in their own way and according to their own experience. The valuable contribution of each documental and bibliographic analysis is to understand and assimilate the most important issues in each of them. We can see that our own enterprises organized the Mexican way, can be subject to up-dating and continuous improvement in their internal structure. All these statements are valid, as long as we have the capacity and talent to know how to adapt and adopt them to our own circumstances. Nowadays, the control over these matters belongs to American authors. We need to locate the medullar issue that will allow Mexican enterprises to grow under their own methodology avoiding the effect of other cultures by acquiring foreign techniques or management methods and trying to adopt them immediately without proper examination and previous analysis. The challenge for agribusinesses in Mexico, including agricultural, farming and agribusiness developments, is to gradually change with business maturity management techniques, according to the size and conditions of each enterprise, in order to compete first in the national market and then worldwide. The present applied research essay seeks to develop a synthesis of these concepts and state the experience of how the technique called STRATEGIC AGRIBUSINESS MANAGEMENT PROCESS, PAAE (for its initials in Spanish), has been incorporated in the agribusiness scope. This line of research has been improved for more than three decades in order to be successfully applied in the rural environment.
Factorization of the Q^2 dependence in electroproduction of vector mesons

description: In a framework for nonperturbative QCD calculation of high energy processes, the amplitudes for photo- and electroproduction of vector mesons are written as integrals of the overlap product of photon and vector meson wave functions, multiplied by the amplitude for the scattering of $q\bar{q}$ dipole pairs off the proton. For sizes of the overlap functions that are smaller than the typical ranges of the interaction of the dipoles with the proton, the amplitudes factorize in the form of integrals, here called overlap strengths, formed only with the overlap of the wave functions times the square of the dipole separation. The integration is extended over the light front coordinates describing the $q\bar{q}$ dipoles. With this result, the overlap strengths contain all $Q^2$ dependence of the observables. We show the importance of this factorization in the description of the experimental data for all S-wave vector mesons.

description: To quantify the effects of a policy of imports on the market of sorghum in Mexico, a model of spatial and intertemporal nonlinear programming was validated in 2013. Under optimization, production, imports and consumption were 6.2, 2.3 and 8.4 million tons the net social value of 52,377.4 million, 2.3 times the level observed in that year. Reduce imports at 1.5 million tons, domestic producers benefit and harm consumers; imports increased at the same volume, it would have benefited consumers and hurt producers. Such results should be considered for an efficient distribution of the grain.

Intrinsic spin Hall effect in topological insulators: A first-principles study

description: The intrinsic spin Hall conductivity of typical topological insulators Sb$_2$Se$_3$, Sb$_2$Te$_3$, Bi$_2$Se$_3$, and Bi$_2$Te$_3$ in the bulk form, is calculated from first-principles by using density functional theory and the linear response theory in a maximally localized Wannier basis. The results show that there is a finite spin Hall conductivity of 100--200 ($\hbar$/2e)(S/cm) in the vicinity of the Fermi energy. Although the resulting values are an order of magnitude smaller than that of heavy metals, they show a comparable spin Hall angle due to their relatively lower longitudinal conductivity. The spin Hall angle for different compounds are then compared to that of recent experiments on topological-insulator/ferromagnet heterostructures. The comparison suggests that the role of the bulk in generating a spin current and consequently a spin torque in magnetization switching applications is comparable to that of the surface including the spin-momentum locked surface states and the Rashba-Edelstein effect at the interface.

description: Tilted disk precession exists in different objects. Negative superhumps (NSHs) in cataclysmic variable stars (CVs) are believed to arise from the interaction between the reverse precession of a tilted disk and the streams from the secondary star.Utilizing TESS photometry, we present a comprehensive investigation into the tilted disk precession and NSHs in the dwarf nova (DN) HS 2325+8205, employing eclipse minima, eclipse depths, NSH frequencies, and NSH amplitudes and the correlation between them as the windows. We identified NSHs with a period of 0.185671(17) days in HS 2325+8205. The NSH frequency exhibits variability with a period of 3.943(9) days, akin to the tilted disk precession period validated in novae-like stars (NLs, SDSS J0812) and intermediate polars (IPs, TV Col).The O-C of eclipse minima were similarly found to vary cyclically in period 4.135(5) days, characterized by a faster rise than fall. Furthermore, the NSH amplitude exhibits complex and diverse variations, which may be linked to changes in the disk radius, mass transfer rate, and the apparent area of the hot spot. For the first time in DNe, we observe bi-periodic variations in eclipse depth (P1= 4.131(4) d and P2= 2.065(2) d ~ Pprec/2), resembling those seen in IPs, suggesting that variations with P2 are not attributable to an accretion curtain, as previously suspected. Moreover, NSH amplitude and eclipse depth decrease with increasing NSH frequency, while NSH amplitude correlates positively with eclipse depth.These complex variations observed across multiple observational windows provide substantial evidence for understanding of tilted disk precession and NSHs.
