Strong coupling approach to Mott transition of massless and massive Dirac fermions on honeycomb lattice

description: Phase transitions in the Hubbard model and ionic Hubbard model at half-filling on the honeycomb lattice are investigated in the strong coupling perturbation theory which corresponds to an expansion in powers of the hopping $t$ around the atomic limit. Within this formulation we find analytic expressions for the single-particle spectrum, whereby the calculation of the insulating gap is reduced to a simple root finding problem. This enables high precision determination of the insulating gap that does not require any extrapolation procedure. The critical value of Mott transition on the honeycomb lattice is obtained to be $U_c\approx 2.38 t$. Studying the ionic Hubbard model at the lowest order, we find two insulating states, one with Mott character at large $U$ and another with single-particle gap character at large ionic potential, $Δ$. The present approach gives a critical gapless state at $U=2Δ$ at lowest order. By systematically improving on the perturbation expansion, the density of states around this critical gapless phase reduces.

title:  Legal clinics as a leading force for changes in legal education
Creators: name: Bugatti  , Laura
Publisher: name: Roma TrE-Press
Year: 2023

description: Criticisms of legal education have remained persistent over time, and the need for change and reform is a global concern. The current approach to legal education in civil law countries reflects the need to turn from a dogmatic to a problematic approach in order to consider both practical issues and social demands. Against this backdrop, the paper aims to explore the role played by clinical legal education in order to align continental legal education with this ambition, thereby making law school experiences more educational for students and, at the same time, promoting social justice and upholding the rule of law.

Integrating the Patient Perspective Into Research Design in the US: Case Studies and Recommendations
Creators: name: Cameron, Clifford David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Clinical research-its methodologies, approaches, rigor, review processes, and results dissemination mechanisms-has resulted in tremendous benefits to both individuals and populations throughout its history in the US. Patients have traditionally played a subservient role in medical care-more or less willingly and by design-relying on an elite corps of educated experts to recommend and implement decisions. However, as the field of medicine advances into the 21st century, patients are called upon to make more, and more sophisticated, healthcare decisions with both financial and personal ramifications. As this trend has accelerated, it has become clear that the current state of clinical research has proven inadequate to serve the informational needs of this constituency, and new approaches have been proposed and tested, including those using uniquely 21st century tools, such as social media and ubiquitous technology. While many of these efforts remain in their infancy, a review of several case studies can serve to illuminate trends and results, and enable recommendations and conclusions that can assist in the future of patient-centered research. From this analysis, several major themes become apparent. First, the best patient-centered research directly assessed patient involvement using both qualitative and quantitative measures. Second, engagement between patients and a variety of stakeholders in the research definition process created synergies and insights that would not otherwise have revealed themselves, including a virtuous cycle that increased patient interest and involvement in general. Third, creating a systemic platform for on-going patient engagement can have long-lasting value through fundamental changes to the culture of research prioritization and design. These foundational benefits occur independently of the timing, nature and method of harnessing patient feedback, as well as the quantity of that feedback. Patient-centered research, however, is still research and, as such, should function within the time-tested framework (ethical and otherwise) for conducting research. However, the evidentiary objectives of that research need to incorporate patient input in order to create a level playing field, and a common language, for the doctor-patient relationship. Research that addresses these themes will enable patients to more readily participate in today's healthcare system. Systemic participation will, moreover, provide value to the patient through collaboration with other stakeholders to identify optimal individualized care plans, make better informed decisions, and ultimately improve outcomes-all through focusing on the practicalities of the patient's life and treatment journey.

description: Short-duration gamma-ray bursts (SGRBs) are widely believed to be powered by the mergers of compact binaries, such as binary neutron stars or possibly neutron star-black hole binaries. Though the prospect of detecting SGRBs with gravitational wave (GW) signals by the advanced Laser Interferometer Gravitational-Wave Observatory (LIGO)/VIRGO network is promising, no known SGRB has been found within the expected advanced LIGO/VIRGO sensitivity range for binary neutron star systems. We find, however, that the two long-short GRBs (GRB 060505 and GRB 060614) may be within the horizon of advanced GW detectors. In the upcoming era of GW astronomy, the merger origin of some long-short GRBs, as favored by the macronova signature displayed in GRB 060614, can be unambiguously tested. The model-dependent time lags between the merger and the onset of the prompt emission of the GRB are estimated. The comparison of such time lags between model predictions and the real data expected in the era of the GW astronomy would be helpful in revealing the physical processes taking place at the central engine (including the launch of the relativistic outflow, the emergence of the outflow from the dense material ejected during the merger, and the radiation of gamma rays). We also show that the speed of GWs, with or without a simultaneous test of Einstein's equivalence principle, can be directly measured to an accuracy of $\sim 3\times 10^{-8}~{\rm cm~s^{-1}}$ or even better in the advanced LIGO/VIRGO era.

description: In this paper, we first introduce a multi-field setup of Cuscuton gravity in a curved field space manifold. Then, we show that this model allows for a regular bouncing cosmology and it does not lead to ghosts or other instabilities at the level of perturbations. More precisely, by decomposing the scalar fields perturbations into the tangential and normal components with respect to the background field space trajectory, the entropy mode perpendicular to the background trajectory is healthy which directly depends on the signature of the field-space metric, whereas the adiabatic perturbation tangential to the background trajectory is frozen. In analogy with the standard Cuscuton theory equipped with an extra dynamical scalar field, the adiabatic field does not have its own dynamics, but it modifies the dynamics of other dynamical fields like entropy mode in our scenario. Finally, we perform a Hamiltonian analysis of our model in order to count the degrees of freedom propagated by dynamical fields.

description: The evaluation of the interaction between objects arranged on a lattice requires the computation of lattice sums. A scenario frequently encountered are systems governed by the Helmholtz equation in the context of electromagnetic scattering in an array of particles forming a metamaterial, a metasurface, or a photonic crystal. While the convergence of direct lattice sums for such translation coefficients is notoriously slow, the application of Ewald's method converts the direct sums into exponentially convergent series. We present a derivation of such series for the 2D and 3D solutions of the Helmholtz equation, namely spherical and cylindrical solutions. When compared to prior research, our novel expressions are especially aimed at computing the lattice sums for several interacting sublattices in 1D lattices (chains), 2D lattices (gratings), and 3D lattices. We verify our results by comparison with the direct computation of the lattice sums.
Hepatitis C A Public Health Treat: Review of Current Recommendations and Strategies
Creators: name: Sanderson, Shana M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Hepatitis C virus (HCV) is the most common chronic bloodborne infection in the United States. (Centers for Disease, 1998) It is estimated that 3.9 million to 5 million of the US population is infected with tbis virus. Transmission of HCV occurs primarily to those who have been exposed to large or repeated direct contact with infected blood. Persons at risk of exposure include those who have injected drug use, blood transfusions before 1992, solid organ transplantation from infected donors, unsafe medical practices, and occupational exposures to infected blood, and birth to an infected mother, and sex with an infected person, high-risk sexual practices, and possibly intranasal cocaine use. Hepatitis C is a common cause of cirrhosis, hepatocellular carinoma (HCC), and the most common reason for liver transplantation. Current recommendations from the Center for Disease Control, National Institutes of Health, and United States Preventative Service Task Force (USPSTF) disagree on who is considered high risk for infection and who should be tested for HCV. Health care costs predictions for hepatitis C in the absence of liver transplant have been high. Research, recommendations, and policies need to be addressed to fight this Public Health Problem.

description: The properties of the interstellar medium (ISM) surrounding a planetary system can impact planetary climate through a number of mechanisms, including changing the size of the astrosphere (one of the major shields for cosmic rays) as well as direct deposition of material into planetary atmospheres. In order to constrain the ambient ISM conditions for exoplanetary systems, we present observations of interstellar Na I and K I absorption towards seventeen early-type stars in the Kepler prime mission field of view. We identify 39 Na I and 8 K I velocity components, and attribute these to eleven ISM clouds. Six of these are detected towards more than one star, and for these clouds we put limits on the cloud properties, including distance and hydrogen number density. We identify one cloud with significant (>1.5 cm$^{-3}$) hydrogen number density located within the nominal ~100 pc boundary of the Local Bubble. We identify systems with confirmed planets within the Kepler field of view that could lie within these ISM clouds, and estimate upper limits on the astrosphere sizes of these systems under the assumption that they do lie within these clouds. Under this condition, the Kepler-20, 42, and 445 multiplanet systems could have compressed astrospheres much smaller than the present-day heliosphere. Among the known habitable zone planet hosts, Kepler-186 could have an astrosphere somewhat smaller than the heliosphere, while Kepler-437 and KOI-4427 could have astrospheres much larger than the heliosphere. The thick disk star Kepler-444 may have an astrosphere just a few AU in radius.

description: When two Bose-Einstein condensates -- labelled 1 and 2 -- overlap spatially, the equilibrium state of the system depends on the miscibility criterion for the two fluids. Here, we theoretically focus on the non-miscible regime in two spatial dimensions and explore the properties of the localized wave packet formed by the minority component 2 when immersed in an infinite bath formed by component 1. We address the zero-temperature regime and describe the two-fluid system by coupled classical field equations. We show that such a wave packet exists only for an atom number $N_2$ above a threshold value corresponding to the Townes soliton state. We identify the regimes where this localized state can be described by an effective single-field equation up to the droplet case, where component 2 behaves like an incompressible fluid. We study the near-equilibrium dynamics of the coupled fluids, which reveals specific parameter ranges for the existence of localized excitation modes.

title:  “The reproduction of hierarchy” in italian law departments and innovative teaching. The role of law clinics
Creators: name: Capuzzo , Giacomo
Publisher: name: Roma TrE-Press
Year: 2023

description: The topic of innovative teaching must be framed through a discourse that recognizes the eminently political nature of law departments. It is not possible to disregard, in the study of legal education, the fact that courses of study and teaching activities have nothing merely technical and
neutral about them; they are practices and tools that are functional in placing students within social hierarchies proper to the legal world that awaits them. The law department is thus a hierarchically organized space in which students are taught the body of knowledge necessary to be part of that hierarchy. Every aspect of legal education is functional to hierarchical reproduction, from classes to curricula to teaching methods. The goal of critical study is to question legal education, expose the ideology behind it and propose alternative practices. In this sense, clinical legal education (CLE) can be conceived of as an innovative teaching that eschews hierarchical reproduction, as long as it is configured as a transformative practice that aims to protect general interests through collective conceived access to courts. In this way, students are immersed in an alternative, egalitarian educational space of shared and interdisciplinary knowledge.

description: Parafermions are the simplest generalizations of Majorana fermions that realize topological order. We propose a less restrictive notion of topological order in 1D open chains, which generalizes the seminal work by Fendley [J. Stat. Mech., P11020 (2012)]. The first essential property is that the groundstates are mutually indistinguishable by local, symmetric probes, and the second is a generalized notion of zero edge modes which cyclically permute the groundstates. These two properties are shown to be topologically robust, and applicable to a wider family of topologically-ordered Hamiltonians than has been previously considered. An an application of these edge modes, we formulate a new notion of twisted boundary conditions on a closed chain, which guarantees that the closed-chain groundstate is topological, i.e., it originates from the topological manifold of degenerate states on the open chain. Finally, we generalize these ideas to describe symmetry-breaking phases with a parafermionic order parameter. These exotic phases are condensates of parafermion multiplets, which generalizes Cooper pairing in superconductors. The stability of these condensates are investigated on both open and closed chains.

description: The development of neuromorphic systems based on memristive elements - resistors with memory - requires a fundamental understanding of their collective dynamics when organized in networks. Here, we study an experimentally inspired model of two-dimensional disordered memristive networks subject to a slowly ramped voltage and show that they undergo a first-order phase transition in the conductivity for sufficiently high values of memory, as quantified by the memristive ON/OFF ratio. We investigate the consequences of this transition for the memristive current-voltage characteristics both through simulation and theory, and uncover a duality between forward and reverse switching processes that has also been observed in several experimental systems of this sort. Our work sheds considerable light on the statistical properties of memristive networks that are presently studied both for unconventional computing and as models of neural networks.

description: Three-dimensional discrete dislocation dynamics simulations are used to study strain-controlled plastic deformation of face-centered cubic aluminium single crystals. After describing the rate and size dependence of the average stress-strain curves, we study the power-law distributed strain bursts and the average avalanche shapes, and find a universal power-law exponent $τ\approx 1.0$ for all imposed strain rates and system sizes, characterizing both the event sizes and their durations. We discuss the dependence of our results on loading rate and compare these with previous studies of strain-controlled two-dimensional systems of discrete dislocations as well as of quasistatic stress-controlled loading of aluminium single crystals.

description: Lead and its effects on the human body have been a major concern around the world for decades. This concern is not just for workers exposed to lead in industry, but there is also concern for the general public as well. In the United States (U.S.), there has been a major effort to reduce lead exposures to the general public since the 1970s with the removal of lead from gasoline. This has reduced blood lead levels dramatically in the public sector (International Lead Association [ILA], 2016). Lead bearing manufacturers have taken great steps to reduce worker exposures to all time low blood lead levels in the past two decades as well. With an Occupational Safety and Health Act (OSH Act) standard that is almost 40 years old, regulatory changes are sure to be coming. The lead industry plans to be a part of those positive changes and has shown proof of their commitment to blood lead reduction of worker blood leads industry wide. These reductions will help to pave the way for regulatory changes in the future. In addition, there are many new studies published in the recent past about lead and its effects on the body. This ongoing research is crucial to continuous improvement of lead reduction programs for the future. The occupational health team must constantly be looking for new and innovative ways to coach workers to reduce blood lead levels. This innovation will only be realized through a team approach in collaboration with industry experts to share knowledge gained by new programs initiated.

description: Ultrashort and intense extreme ultraviolet (XUV) and X-ray pulses readily available at free-electron lasers (FELs) enable studying non-linear light−matter interactions on femtosecond timescales. Here, we report on the non-linear fluence dependence of magnetic scattering of Co/Pt multilayers, using FERMI FEL’s 70-fs-long single and double XUV pulses, the latter with a temporal separation of 200 fs, with a photon energy slightly detuned to the Co M2,3 absorption edge. We observe a quenching in magnetic scattering that sets-in already in the non-destructive fluence regime of a few mJ/cm² typically used for FEL-probe experiments on magnetic materials. Calculations of the transient electronic structure in tandem with a phenomenological modeling of the experimental data by means of ultrafast demagnetization unambiguously show that XUV-radiation-induced demagnetization is the dominant mechanism for the quenching in the investigated fluence regime of <50 mJ/cm², while light-induced changes of the electronic core levels are predicted to additionally occur at higher fluences. The modeling of the data further indicates that the demagnetization proceeds on the sub-20-fs timescale. This ultrashort timescale is consistent with non-coherent models for ultrafast demagnetization, considering the sub-femtosecond lifetime of hot electrons with energies of a few 10 eV generated by the XUV radiation.

description: Heterodyne cavity experiments for gravitational wave (GW) detection experience a rising interest since recent studies showed that they allow to probe the ultra high frequency regime above $10\,\text{kHz}$. In this paper, we present a concise theoretical study of the experiment based on ideas from the former MAGO collaboration which already started experiments in turn of the millenium. It extends the former results via deriving an additional term originating from a back-action of the electromagnetic field on the cavity walls, also known as Lorentz Force Detuning. We argue that this term leads to a complex dependence of the signal power $P_{\text{sig}}$ on the coupling coefficient between the mechanical shell modes and the electromagnetic eigenmodes of the cavity. It turns out that one has to adapt the coupling over the whole parameter space since the optimal value depends on the mechanical mode $\omega_l$ and the GW frequency $\omega_g$. This result is particularly relevant for the design of future experiments.

description: The GammaTPC is an MeV-scale single-phase liquid argon time-projection-chamber gamma-ray telescope concept with a novel dual-scale pixel-based charge-readout system. It promises to enable a significant improvement in sensitivity to MeV-scale gamma-rays over previous telescopes. The novel pixel-based charge readout allows for imaging of the tracks of electrons scattered by Compton interactions of incident gamma-rays. The two primary contributors to the accuracy of a Compton telescope in reconstructing an incident gamma-ray's original direction are its energy and position resolution. In this work, we focus on using deep learning to optimize the reconstruction of the initial position and direction of electrons scattered in Compton interactions, including using probabilistic models to estimate predictive uncertainty. We show that the deep learning models are able to predict locations of Compton scatters of MeV-scale gamma-rays from simulated pixel-based data to better than 0.6 mm RMS error, and are sensitive to the initial direction of the scattered electron. We compare and contrast different deep learning uncertainty estimation algorithms for reconstruction applications. Additionally, we show that event-by-event estimates of the uncertainty of the locations of the Compton scatters can be used to select those events that were reconstructed most accurately, leading to improvement in locating the origin of gamma-ray sources on the sky.

title: Investigating the use of oral paracetamol and topical non-steroidal anti-inflammatory drug (NSAID) - diclofenac as a combination therapy for mild to moderate osteoarthritis (OA) pain: an evidence-based assessment using data mining and the application of machine learning (ML)

description: Osteoarthritis (OA) is a major cause of chronic pain and disability in older adults and currently affects more than 500 million people worldwide. However, pain management in OA continues to remain suboptimal. The use of combination therapy of oral acetaminophen (APAP) and topical diclofenac (DIC), exhibiting complementary mechanisms of action, is an attractive strategy to achieve effective pain relief. However, there is limited information on the use of this combination for OA pain management. This study uses modified Delphi methodology to gather the perspectives of expert healthcare professionals (HCPs) towards the use of APAP either as monotherapy or in combination with topical NSAIDs in three different geographies, including Australia, Malaysia, and Sweden. The research shows that while oral APAP remains the gold standard treatment for the HCPs, there is limited prescription uptake for its combination with topical NSAIDs due to a lack of strong scientific evidence on their efficacy. In the absence of evidence on the combination in OA pain, the study uses a model-based meta-analysis (MBMA), a robust statistical technique, to extrapolate the combination effect from published studies conducted in acute pain setting. The MBMA indicates greater pain reduction and opioid sparing effect for the combination versus APAP monotherapy. Given the overlap in the pathophysiology of acute and chronic pain, similar beneficial effects from the use of combination can be expected on extrapolation to OA pain. Additionally, while topical DIC is considered well-tolerated due to its low systemic exposure, concerns of liver toxicity with APAP at standardised doses remain. Therefore, a separate MBMA is implemented to investigate the association between APAP and risk of hepatotoxicity. The MBMA demonstrates short-term (8-16 weeks) APAP use at standard analgesic doses (≤4000 mg/day) to be associated with a very low risk of clinically meaningful liver injury when compared with placebo. The findings in the study contribute to bridging the evidence gap in the literature on the efficacy and tolerability of combination of oral APAP and topical DIC in the management of mild to moderate OA pain.

description: We examine the repeatability, reliability, and accuracy of differential exoplanet eclipse depth measurements made using the InfraRed Array Camera (IRAC) on the Spitzer Space Telescope during the post-cryogenic mission. We have re-analyzed an existing 4.5 μm data set, consisting of 10 observations of the XO-3b system during secondary eclipse, using seven different techniques for removing correlated noise. We find that, on average, for a given technique, the eclipse depth estimate is repeatable from epoch to epoch to within 156 parts per million (ppm). Most techniques derive eclipse depths that do not vary by more than a factor 3 of the photon noise limit. All methods but one accurately assess their own errors: for these methods, the individual measurement uncertainties are comparable to the scatter in eclipse depths over the 10 epoch sample. To assess the accuracy of the techniques as well as to clarify the difference between instrumental and other sources of measurement error, we have also analyzed a simulated data set of 10 visits to XO-3b, for which the eclipse depth is known. We find that three of the methods (BLISS mapping, Pixel Level Decorrelation, and Independent Component Analysis) obtain results that are within three times the photon limit of the true eclipse depth. When averaged over the 10 epoch ensemble, 5 out of 7 techniques come within 60 ppm of the true value. Spitzer exoplanet data, if obtained following current best practices and reduced using methods such as those described here, can measure repeatable and accurate single eclipse depths, with close to photon-limited results.
