description: The medial preoptic area (mPOA), located in the rostral hypothalamus, is an important regulator of motivated behaviors in rats. While its role in naturally rewarding behaviors, such as maternal care and sexual behavior, is well established, its role in drug response is just beginning to be explored. As a major site of neuroendocrine integration with direct connections to the mesolimbic dopamine system, it is not surprising that the mPOA is implicated in the modulation of sex differences in reward responses. Prior work has demonstrated that activation of the mPOA in response to sexual and parental reward differs between males and females, but whether sex differences are present in medial preoptic responses to drugs of abuse is unknown. Here, a role for the mPOA in the regulation of neuroendocrine-induced sex differences in neural and behavioral responses to cocaine is uncovered. Furthermore, while it is known that the mPOA influences the mesolimbic dopamine system through efferent connections with the ventral tegmental area (VTA), whether there are sex differences in the extent and profile of these projections remains unclear. The use of an iontophoretically injected tract-tracer, in conjunction with immunohistochemical techniques, revealed sex differences in mPOA efferents to the VTA. Specifically, projections from the central mPOA to the VTA contain more estrogen receptors and fewer androgen receptors in females, compared to males. Taken together, this work identifies the mPOA as a modulator of neuroendocrine-induced sex differences in downstream reward processing.
Visualizing Surface Morphology of Sedimentary Charred Botanical Particles Using Tangential Flash Macrophotography

description: Charred fragments of botanical materials in sediments provide important clues as to the historic fire regime of an area. Lacustrine deposits may include a record of many thousands of years, including information about the sources of plant materials. According to previous morphotype syntheses, charred plant materials can be attributed at the biome scale to certain plant groups such as arboreal taxa, monocots, including Poaceae, and at the individual species scale, to certain plant parts such as wood and leaves. Additionally, morphotypes may reflect seasonal timing of burning, fuel moisture, and potentially even taphonomic processes. Particle size has been linked to charcoal dispersal with important implications on area sources for paleoecological reconstructions. High-resolution visualization allows more accurate identification of informative morphotypes for a particular biome as well as more precise morphometrics. This has been achieved for submillimeter fragments (100-500µ) by photography using tangential flash illumination. Sedimentary charcoal samples were fractionated through fine sieves by standard procedures. Individual particles or liquid suspensions were then placed on a highly transparent substrate and allowed to dry in situ. High-resolution photography was performed using a Canon R5 mirrorless camera with a 65mm macro lens set at 5x magnification. This provides a field of view of 7.2 x 4.8 mm at a working distance of about 42 mm. Sample slides are mounted several centimeters above a white background. A dual flash system mounted on the lens creates a tangential illumination of the sample, along with strong back-lighting. Depth of field is very limited so a series of exposures are made at intervals of 100µ and these are then processed by focus-stacking software. The resulting images are sharp through the entire range with the surface texture strongly highlighted. Effective magnification is approximately 400x. The method will be illustrated with samples derived from sediments in the fynbos of South Africa, the tropical Andes of South America, and plant materials charred under controlled burning.

description: We study the behavior of skyrmions in thin films under the action of stochastic torques arising from thermal fluctuations. We find that the Brownian motion of skyrmions is described by a stochastic Thiele's equation and its corresponding Fokker-Planck equation. The resulting Fokker-Planck equation is recognized as the one for a high-friction Brownian particle which has been studied extensively in different physical contexts. It is shown that thermal fluctuations favor the skyrmion motion allowing a finite mobility even in presence of pinning traps. We calculate explicitly the mobility tensor of skyrmions in linear response to an electric current finding that it increases with temperature.
Harder Course, Higher Score? Exploring the Heterogeneous Effects of Eighth-grade Algebra Enrollment on Average Math Achievement
Creators: name: Li, Jierui
Publisher: name: University of Chicago
Year: 2023

description: Many empirical studies have provided evidence both supporting and opposing the practice of detracking. While some researchers have shown that high-achieving students from disadvantaged backgrounds can be disadvantaged by detracking, there has been limited research on how this within-school revolution may impact the achievement gap between schools. To address this gap, this study applies a propensity score-based method to hierarchical models and utilizes data from the Early Childhood Longitudinal Study—Kindergarten class of 1998–1999 (ECLS-K) in order to explore the causal inference of expanding algebra access. More specifically, it examines the average and heterogeneous effects of enrolling more eighth-grade students in algebra on school average achievement. The study finds, in conclusion, that enrolling all students in algebra has insignificant effect on school average test scores due to the heterogeneity of the effect. Only high-achieving schools benefit from this comprehensive detracking process, resulting in an increase in the achievement gap between schools. However, for schools that do not offer algebra, enrolling some students in algebra increases their average achievement without significant differences in the effects among different schools. These findings provide insights into how course offering policies should be implemented among schools.

description: Even if the unification and supersymmetry breaking scales are around $10^6$ to $10^{9}$ TeV, a large $A_t$ coupling may be entirely generated at low energies through RGE evolution in the 5D MSSM. Independent of the precise details of supersymmetry breaking, we take advantage of power law running in five dimensions and a compactification scale in the $10-10^3$ TeV range to show how the gluino mass may drive a large enough $A_t$ to achieve the required $125.5$ GeV Higgs mass. This also allows for sub-TeV stops, possibly observable at the LHC, and preserving GUT unification, thereby resulting in improved naturalness properties with respect to the four dimensional MSSM. The results apply also to models of "split families" in which the first and second generation matter fields are in the bulk and the third is on the boundary, which may assist in the generation of light stops whilst satisfying collider constraints on the first two generations of squarks.

title: Early modernism and the English short story, 1890-1920
Creators: name: March Russell, Paul Andrew
Publisher: name: University of Kent
Year: 2022

description: The following themes are explored: the proliferation of the short story in relation to nascent modernism; the ideological preconditions for formal change, specifically a crisis within “Englishness”; and lastly, the growth of modernism in response to the unadaptability of dominant literary modes to cultural unrest. Despite a recent recourse to critical theory, short story criticism remains principally formalist in approach, and therefore reasserts the preferences of its original theorists. The emphasis upon symmetrical design can be traced back to the late Victorian ideology of vitalism. Fears of cultural degeneration mediate the apparent displacement of an organic ideal, defined in terms of autonomy, purity and instinct, and internalised through the pastoral iconography associated with England. The call for symmetry within early short story criticism colludes with this ideal, but also denies the actuality of an urban, technocratic and atomistic society. Symmetry, in that sense, explains the popularisation of the short story since it conspires with the lifelike attachment between word and object, and distantiation of alterity, which underpin the dominant genres of realism and romance. The literary market, though, was being divided by the internecine struggle between those two genres with the result that the novel was stalemated, by association, as an aesthetic product. Early modernism is comparatively progressive by centring absence and ambiguity within a critical encounter with alterity, whilst retaining a residual desire for cultural renewal. Early modernists adopt the short story not just for its innate emphasis upon ellipsis and paradox, but for its metaphorical association with the scientific changes, which were disrupting the organic ideal. Modernism foregrounds the manufactured nature of the short story, and therefore the transparency of symmetry. The interrogation of symmetry, however, exposes early modernism’s own residual organicism, and anticipates its eventual dissolution. The modernist short story, though, presages the transformation of the novel.

description: The article aims to assess the activities of Local Action Groups (LAGs) in the region of Lublin. The research hypothesis, that territorial partnerships are an important factor in local development, LAG support is seen by local communities through the implementation of grant projects to support the well-being of residents, was verified with the use of research questions. 114 members of LAGs located in the area of Lublin took part in the study, which was based on a research questionnaire prepared by the author of the paper, and 238 participants in the projects implemented by the LAGs took part in direct interviews. The research was conducted in the period from August to September 2019. The descriptive statistics of the STATISTICA 13.1 PL software were used to process the obtained results. Based on the outcomes of the research, the most important motives for joining the partnership were social reasons – the need to act for the benefit of the local community, and reasons of an egoistic nature – the need to introduce changes in the environment that would help self-development, or the willingness to form beneficial relationships. It was also the curiosity about the new form of cooperation. The research participants also ranked the main goals of the LAGs, as well as the categories of projects that should be supported. Among their expectations, the participants in the interviews mentioned: supporting and developing non-agricultural activities, actions to reduce unemployment and supporting the establishment of international cooperation.
The frustrated spin-$\frac{1}{2}$ $J_{1}$--$J_{2}$ isotropic $XY$ model on the honeycomb lattice

description: We study the zero-temperature ground-state (GS) phase diagram of a spin-half $J_{1}$--$J_{2}$ $XY$ model on the honeycomb lattice with nearest-neighbor exchange coupling $J_{1}>0$ and frustrating next-nearest-neighbor exchange coupling $J_{2} \equiv κJ_{1}>0$, where both bonds are of the isotropic $XY$ type, using the coupled cluster method. Results are presented for the GS energy per spin, magnetic order parameter, and staggered dimer valence-bond crystalline (SDVBC) susceptibility, for values of the frustration parameter in the range $0 \leq κ\leq 1$. In this range we find phases exhibiting, respectively, Néel $xy$ planar [N(p)], Néel $z$-aligned [N($z$)], SDVBC, and Néel-II $xy$ planar [N-II(p)] orderings which break the lattice rotational symmetry. The N(p) state, which is stable for the classical version of the model in the range $0 \leq κ\leq \frac{1}{6}$, is found to form the GS phase out to a first quantum critical point at $κ_{c_{1}} = 0.216(5)$, beyond which the stable GS phase has N($z$) order over the range $κ_{c_{1}} < κ< κ_{c_{2}}=0.355(5)$. For values $κ> κ_{c_{2}}$ we find a strong competition to form the GS phase between states with N-II(p) and SDVBC forms of order. Our best estimate, however, is that the stable GS phase over the range $κ_{c_{2}} < κ< κ_{c_{3}} \approx 0.52(3)$ is a mixed state with both SDVBC and N-II(p) forms of order; and for values $κ> κ_{c_{3}}$ is the N-II(p) state, which is stable at the classical level only at the highly degenerate point $κ=\frac{1}{2}$. Over the range $0 \leq κ\leq 1$ we find no evidence for any of the spiral phases that are present classically for all values $κ> \frac{1}{6}$, nor for any quantum spin-liquid state.

description: We discuss complementarity of discovery reaches of heavier neutral Higgs bosons and charged Higgs bosons at the LHC and the International Linear Collider (ILC) in two Higgs doublet models (2HDMs). We perform a comprehensive analysis on their production and decay processes for all types of Yukawa interaction under the softly-broken discrete symmetry which is introduced to avoid flavour changing neutral currents, and we investigate parameter spaces of discovering additional Higgs bosons at the ILC beyond the LHC reach. We find that the 500 GeV run of the ILC with the integrated luminosity of 500 fb^{-1} shows an advantage for discovering the additional Higgs bosons in the region where the LHC cannot discover them with the integrated luminosity of 300 fb^{-1}. For the 1 TeV run of the ILC with the integrated luminosity of 1 ab^{-1}, production processes of an additional Higgs boson associated with the top quark can be useful as discovery channels in some parameter spaces where the LHC with the integrated luminosity of 3000 fb^{-1} cannot reach. It is emphasized that the complementary study at the LHC and the ILC is useful not only to survey additional Higgs bosons at the TeV scale, but also to discriminate types of Yukawa interaction in the 2HDM.

description: This Letter is based on the $κ$-Dirac equation, derived from the $κ$-Poincaré-Hopf algebra. It is shown that the $κ$-Dirac equation preserves parity while breaks charge conjugation and time reversal symmetries. Introducing the Dirac oscillator prescription, $\mathbf{p}\to\mathbf{p}-imωβ\mathbf{r}$, in the $κ$-Dirac equation, one obtains the $κ$-Dirac oscillator. Using a decomposition in terms of spin angular functions, one achieves the deformed radial equations, with the associated deformed energy eigenvalues and eigenfunctions. The deformation parameter breaks the infinite degeneracy of the Dirac oscillator. In the case where $\varepsilon=0$, one recovers the energy eigenvalues and eigenfunctions of the Dirac oscillator.

description: We study black holes in the infrared sector of three-dimensional Hořava gravity. It is shown that black hole solutions with anti-de Sitter asymptotics are admissible only in the sector of the theory in which the scalar degree of freedom propagates infinitely fast. We derive the most general class of stationary, circularly symmetric, asymptotically anti-de Sitter black hole solutions. We also show that the theory admits black hole solutions with de Sitter and flat asymptotics, unlike three-dimensional general relativity. For all these cases, universal horizons may or may not exist depending on the choice of parameters. Solutions with de Sitter asymptotics can have universal horizons that lie beyond the de Sitter horizon.

description: We construct a rational integrable system (the rational top) on a coadjoint orbit of ${\rm SL}_N$ Lie group. It is described by the Lax operator with spectral parameter and classical non-dynamical skew-symmetric $r$-matrix. In the case of the orbit of minimal dimension the model is gauge equivalent to the rational Calogero-Moser (CM) system. To obtain the results we represent the Lax operator of the CM model in two different factorized forms -- without spectral parameter (related to spinless case) and another one with the spectral parameter. The latter gives rise to the rational top while the first one is related to generalized Cremmer-Gervais $r$-matrices. The gauge transformation relating the rational top and CM model provides a classical rational version of the IRF-Vertex correspondence. From a geometrical point of view it describes the modification of ${\rm SL}(N,\mathbb C)$-bundles over degenerated elliptic curve. In view of Symplectic Hecke Correspondence the rational top is related to the rational spin CM model. Possible applications and generalizations of the suggested construction are discussed. In particular, the obtained $r$-matrix defines a class of KZB equations.

description: The aim of the article is to present the most important issues and key information regarding the concept of foster farms in shaping local development. The article uses the method of analysis of secondary materials, including the literature on the subject – Systematic Literature Review (SLR). Theoretical and practical conditions, methods and hitherto effects of implementing the concept of care farms were presented. An example of a caring farm with regard to the services provided was presented. The role and significance of this type of services are presented, which are undoubtedly an attractive product (service) that can be used by seniors. The establishment of foster farms in rural Poland is an innovative idea that is implemented in the context of social agriculture. In the future, social farming activities (social farming) can contribute to the sustainable development of rural areas. This will enable an increasingly sustainable development of rural areas by reducing poverty and increasing farm incomes. Such activities can stabilize social and economic life in rural areas.

description: In the recently discovered topological crystalline insulators SnTe and Pb_{1-x}Sn_{x}(Te,Se), crystal symmetry and electronic topology intertwine to create topological surface states with many interesting features including Lifshitz transition, Van-Hove singularity and fermion mass generation. These surface states are protected by mirror symmetry with respect to the (110) plane. In this work we present a comprehensive study of the effects of different mirror-symmetry-breaking perturbations on the (001) surface band structure. Pristine (001) surface states have four branches of Dirac fermions at low-energy. We show that ferroelectric-type structural distortion generates a mass and gaps out some or all of these Dirac points, while strain shifts Dirac points in the Brillouin zone. An in-plane magnetic field leaves surface state gapless, but introduces asymmetry between Dirac points. Finally, an out-of-plane magnetic field leads to discrete Landau levels. We show that the Landau level spectrum has an unusual pattern of degeneracy and interesting features due to the unique underlying band structure. This suggests that Landau level spectroscopy can detect and distinguish between different mechanisms of symmetry breaking in topological crystalline insulators.

description: We report the experimental observation of sublattice-resolved resonant scattering in bilayer graphene by performing simultaneous cryogenic atomic hydrogen doping and electron transport measurements in an ultrahigh vacuum. This allows us to monitor the hydrogen adsorption on the different sublattices of bilayer graphene without atomic-scale microscopy. Specifically, we detect two distinct resonant scattering peaks in the gate-dependent resistance, which evolve as a function of the atomic hydrogen dosage. Theoretical calculations show that one of the peaks originates from resonant scattering by hydrogen adatoms on the α sublattice (dimer site) while the other originates from hydrogen adatoms on the β sublattice (nondimer site), thereby enabling a method for characterizing the relative sublattice occupancy via transport measurements. Utilizing this new capability, we investigate the adsorption and thermal desorption of hydrogen adatoms via controlled annealing and conclude that hydrogen adsorption on the β sublattice is energetically favored. Through site-selective desorption from the α sublattice, we realize hydrogen doping with adatoms primarily on a single sublattice, which is highly desired for generating ferromagnetism.

description: Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at sqrt(s[NN]) = 2.76 TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run. The data set includes a sample of ultra-central (0-0.2% centrality) PbPb events collected using a trigger based on total transverse energy in the hadron forward calorimeters and the total multiplicity of pixel clusters in the silicon pixel tracker. A total of about 1.8 million ultra-central events were recorded, corresponding to an integrated luminosity of 120 inverse microbarns. The observed correlations in ultra-central PbPb events are expected to be particularly sensitive to initial-state fluctuations. The single-particle anisotropy Fourier harmonics, from v[2] to v[6], are extracted as a function of particle transverse momentum. At higher transverse momentum, the v[2] harmonic becomes significantly smaller than the higher-order v[n] (n greater than or equal to 3). The pt-averaged v[2] and v[3] are found to be equal within 2%, while higher-order v[n] decrease as n increases. The breakdown of factorization of dihadron correlations into single-particle azimuthal anisotropies is observed. This effect is found to be most prominent in the ultra-central PbPb collisions, where the initial-state fluctuations play a dominant role. A comparison of the factorization data to hydrodynamic predictions with event-by-event fluctuating initial conditions is also presented.

In Ländern wie dem Irak steht bei der Stadtentwicklung meist die effiziente Schaffung von Wohnraum im Vordergrund, aber nicht der Klimaschutz und die Nachhaltigkeit. Für Kalar wurden städtebauliche Optimierungsmaßnahmen entwickelt, die zum einen das aride Klima berücksichtigen und zum anderen auch Kriterien für Nachhaltigkeit sowie Klimaschutz erfüllen. Die Optimierungsmaßnahmen beziehen sich unter anderem auf die Innenstadt, für die ein Leitkonzept entwickelt wurde, aber auch auf die Ausgestaltung eines hierarchisch ausgebauten Straßennetzes, die Gestaltung von neuen Siedlungen und die Entwicklung von Grünflächen, die einen entscheidenden Beitrag zur klimagerechten Gestaltung der Stadt leisten könnten. Die Arbeit beinhaltet eine abschließende kritische Bewertung der Optimierungsmaßnahmen, der zu entnehmen ist, welche Realisierungschancen die Optimierungsmaßnahmen angesichts der politischen, wirtschaftlichen und gesellschaftlichen Situation der Stadt besitzen.

description: Adsorbates can drastically alter physical properties of graphene. Particularly important are adatoms and admolecules that induce resonances at the Dirac point. Such resonances limit electron mobilities and spin relaxation times. We present a systematic tight-binding as well as analytical modeling to investigate the properties of resonant states in the presence of a quantizing magnetic field. Landau levels are strongly influenced by the resonances, especially close to the Dirac point. Here the cyclotron motion of electrons around a defect leads to the formation of circulating local currents which are manifested by the appearance of side peaks around the zero-energy Landau level. Our study is based on realistic parameters for H, F, and Cu adatoms, each exhibiting distinct spectral features in the magnetic field. We also show that by observing a local density of states around an adatom in the presence of Landau levels useful microscopic model parameters can be extracted.

description: The aim of the research was to find out about farmers’ opinions on financial support from the European Union. The development of rural areas and agriculture in Poland significantly accelerated after Poland became a member of the European Union on May 1, 2004. Pre-accession programs made it possible to prepare the agricultural sector for future EU membership, and the subsequent financial perspectives brought a number of programs allowing for the financing and development of the agribusiness sphere, including individual farms. The article presents the results of the research carried out by the survey method using the survey technique carried out in May 2021 among 60 farmers running farms in the Pomeranian Voivodeship. The surveys were collected using the Microsoft Forms available to respondents via social media (Facebook, Instagram, YouTube). The research has shown that European Union funds had a significant impact on the development of farms in the voivodship under study. The financial support was obtained mainly by farms larger than 10 ha, in most cases for purchasing agricultural machines and tractors, and the value of investments usually exceeded 100,000 PLN. It was found that the complexity of the procedures made it difficult to access financial resources, which was why farmers often used the services of agricultural advisors.

description: We describe the quantum evolution of the vacuum Bianchi II universe in terms of the transition amplitude between two asymptotic quantum Kasner-like states. For large values of the momentum variable the classical and quantum calculations give similar results. The difference occurs for small values of this variable due to the Heisenberg uncertainty principle. Our results can be used, to some extent, as a building block of the quantum evolution of the vacuum Bianchi IX universe.

description: The Higgs not only induces the masses of all SM particles, the Higgs, given its special mass value, is the natural candidate for the inflaton and in fact is ruling the evolution of the early universe, by providing the necessary dark energy which remains the dominant energy density. SM running couplings not only allow us to extrapolate SM physics up to the Planck scale, but equally important they are triggering the Higgs mechanism. This is possible by the fact that the bare mass term in the Higgs potential changes sign at about mu_0 = 1.4x10^16 GeV and in the symmetric phase is enhanced by quadratic terms in the Planck mass. Such a huge Higgs mass term is able to play a key role in triggering inflation in the early universe. In this article we extend our previous investigation by working out the details of a Higgs inflation scenario. We show how different terms contributing to the Higgs Lagrangian are affecting inflation. Given the SM and its extrapolation to scales mu>mu_0 we find a calculable cosmological constant V(0) which is weakly scale dependent and actually remains large during inflation. This is different to the Higgs fluctuation field dependent Delta V(phi), which decays exponentially during inflation, and actually would not provide a sufficient amount of inflation. The fluctuation field has a different effective mass which shifts the bare Higgs transition point to a lower value mu'_0 = 7.7x10^14 GeV. The vacuum energy V(0) being proportional to M_Pl^4 has a coefficient which vanishes near the Higgs transition point, such that the bare and the renormalized cosmological constant match at this point. The role of the Higgs in reheating and baryogenesis is emphasized.

description: Aberration kernels describe how harmonic-space multipole coefficients of cosmic microwave background (CMB) observables transform under Lorentz boosts of the reference frame. For spin-weighted CMB observables, transforming like the CMB temperature (i.e. Doppler weight $d = 1$), we show that the aberration kernels are the matrix elements of a unitary boost operator in harmonic space. Algebraic properties of the rotation and boost generators then give simple, exact recursion relations that allow us to raise or lower the multipole quantum numbers $\ell$ and $m$, and the spin weight $s$. Further recursion relations express kernels of other Doppler weights $d \neq 1$ in terms of the $d = 1$ kernels. From those we show that on the full sky, to all orders in $β=v/c$, $E$- and $B$-mode polarization observables do not mix under aberration if and only if $d = 1$. The new relations, fully non-linear in the boost velocity $β$, form the basis of a practical recursive algorithm to accurately compute any aberration kernel. In addition, we develop a second, fast algorithm in which aberration kernels are obtained using a set of ordinary differential equations. This system can also be approximately solved at small scales, providing simple asymptotic formulae for the aberration kernels. The results of this work will be useful for further studying the effect of aberration on future CMB temperature and polarization analysis, and might provide a basis for relativistic radiative transfer schemes.

description: We analyze the classical stability of Q-tubes --- charged extended objects in $(3+1)$-dimensional complex scalar field theory. Explicit solutions were found analytically in the piecewise parabolic potential. Our choice of potential allows us to construct a powerful method of stability investigation. We check that in the case of the zero winding number $n=0$, the previously known stability condition $\partial^2E/\partial Q^2<0$ for Q-balls is fulfilled. However, in the case $n\geq 1$, we find a continuous family of instabilities. Our result has an analogy with the theory of superconductivity of the second type, in which the vortex with $n>1$ becomes unstable towards the decay into the $n$ vortices with the single winding number.

description: Crowdsourcing has gained considerable traction over the past decade and has emerged as a powerful tool in the innovation process of organizations. Given its growing significance in practice, a profound understanding of the concept is crucial. The goal of this study is to develop a comprehensive understanding of designing crowdsourcing projects for innovation by identifying and analyzing critical design elements of crowdsourcing contests. Through synthesizing the principles of the social exchange theory and absorptive capacity, this study provides a novel conceptual configuration that accounts for both the attraction of solvers and the ability of the crowdsourcer to capture value from crowdsourcing contests. Therefore, this paper adopts a morphological approach to structure the four dimensions, namely, (i) task, (ii) crowd, (iii) platform and (iv) crowdsourcer, into a conceptual framework to present an integrated overview of the various crowdsourcing design options. The morphological analysis allows the possibility of identifying relevant interdependencies between design elements, based on the goals of the problem to be crowdsourced. In doing so, the paper aims to enrich the extant literature by providing a comprehensive overview of crowdsourcing and to serve as a blueprint for practitioners to make more informed decisions when designing and executing crowdsourcing projects.
The Structure and Financing of Health Care Systems Affected How Providers Coped With COVID‐19

description: Policy Points - We compared the structure of health care systems and the financial effects of the COVID‐19 pandemic on health care providers in the United States, England, Germany, and Israel: systems incorporating both public and private insurers and providers. - The negative financial effects on health care providers have been more severe in the United States than elsewhere, owing to the prevalence of activity‐based payment systems, limited direct governmental control over available provider capacity, and the structure of governmental financial relief. - In a pandemic, activity‐based payment reverses the conventional financial positions of payers and providers and may prevent providers from prioritizing public health because of the desire to avoid revenue loss caused by declines in patient visits.
Absence of coherent peaks in a $Z_{2}$ fractionalized BCS superconducting state

description: We explore a $Z_{2}$ fractionalized Bardeen-Cooper-Schrieffer (BCS) superconducting state, which is a minimal extension of usual BCS framework. It is found that this state has similar thermal and transport properties, but its single-particle feature strongly deviates from the coherent quasiparticle behavior of the classic/conventional BCS superconducting state. The fingerprint of such $Z_{2}$ BCS state is the absence of the BCS coherent peaks and instead a kink in the local density of state occurs, which in principle could be probed by scanning tunneling microscopy or point-contact spectroscopy experiments. The corresponding exactly soluble models that realize the desirable $Z_{2}$ fractionalized BCS state is presented. In addition, we also study the extended $t$-$U$-$J$ model by using $Z_{2}$ slave-spin representation and find that the $Z_{2}$ BCS state may exist when the paring structure is fully gapped or has nodes. The prototypical wave-function of such a $Z_{2}$ BCS state is also proposed, which could be taken as trial wave-function in current numerical techniques. The present work may be helpful to further study the unconventional superconductivity and its relation to non-Fermi liquids.

Autonomy as Matter of Design: Imagining Total Configurations for the New Machinism
Creators: name: Zehle, Soenke
Publisher: name: Zenodo

Subjects: machinism

description: Rather than an accidental feature of who and where we are, autonomy is a matter of design. Increasingly embedded in our environments, computational technologies challenge our sense of distinct spheres of experience, which in turn are characterized by equally distinct aesthetic and communicative practices. In the actuality of experience, these distinctions have, and have been, collapsed, a consequence of deliberate design strategies around computation-as-ambience, data-driven economies, and invisible interfaces. Innovation idioms around ‘intelligent’ infrastructures – smart home, smart factory, smart city – frame and facilitate the acceleration of an algorithmicization of our core cultural techniques, of the ways in which we explore, organize, and remember what we do and who we are. As ‘autonomy’ becomes the rallying cry of a new machinism, the extent of our individual and collective self-determination is linked to the design of the socio-technical systems that structure and sustain our communicative practices. Which is why the exploration of this linkage between human and machinic autonomy calls for an elaboration of ‘total configurations’ (Dieter Rams) of the situation in which we find ourselves, above and beyond the critical engagement with specific technologies employed to build a world of machinic socialities and subjectivities. This essay imagines a matrix to bring together the design of socio-technical systems with a philosophical sense of design as the ‘unfolding of contradictions’ (Gui Bonsiepe), a matrix to facilitate analysis and reflection of what we do, and who we become, as we embed values in algorithms, data bases, and interfaces that are meant to operate on their own, empowering and exhausting us at the same time.
