description: First results for the implementation of ultrafast laser structured thick-film lithium iron phosphate (LFP) electrodes in cylindrical battery cells are presented, with a special focus on laser structuring without thermal modification of the active material and the winding quality of thick-film electrodes. It was shown in half-cell measurements that minor thermal modifications did not result in a reduction in specific capacity of laser structured electrodes. Cells with structured electrodes had a higher rate capability at discharge C-rates greater than 1C compared to cells with unstructured electrodes. Furthermore, line structured electrodes with a structure pitch of 300 µm showed no visible damage of the electrode coating after winding at a radius of 3 mm, whereby the unstructured reference electrodes showed visible crack formation and delamination from the current collector after winding at a radius of 5 mm.

description: Accessibility is a complex issue that also concerns the fruition of the public space of the city, but in Italy it is presented mainly as yet another aseptic technical-normative requisite to satisfy. The UdR FAL of DIDA born with the intention to widen this term and to spread a new cultural approach in which “accessibility habitat” is transformed into “a great resource for the collective human empowerment, to make it viable, safe and cohesive local communities, for the development of the architectural and landscape heritage”. Or rather “it indicates the ability of a habitat to ensure an independent life to every person, regardless of age, gender, cultural background and the physical, sensory and cognitive”.

description: The characteristic identity formalism discussed in our recent articles is further utilized to derive matrix elements of type 2 unitary irreducible $gl(m|n)$ modules. In particular, we give matrix element formulae for all gl(m|n) generators, including the non-elementary generators, together with their phases on finite dimensional type 2 unitary irreducible representations. Remarkably, we find that the type 2 unitary matrix element equations coincide with the type 1 unitary matrix element equations for non-vanishing matrix elements up to a phase.

description: Aliovalent doping has been adopted to optimize the electrical properties of semiconductors, while its impact on the phonon structure and propagation is seldom paid proper attention to. This work reveals that aliovalent doping can be much more effective in reducing the lattice thermal conductivity of thermoelectric semiconductors than the commonly employed isoelectronic alloying strategy. As demonstrated in the heavy-band NbFeSb system, a large reduction of 65% in the lattice thermal conductivity is achieved through only 10% aliovalent Hf-doping, compared to the 4 times higher isoelectronic Ta-alloying. It is elucidated that aliovalent doping introduces free charge carriers and enhances the screening, leading to the giant softening and deceleration of optical phonons. Moreover, the heavy dopant can induce the avoided-crossing of acoustic and optical phonon branches, further decelerating the acoustic phonons. These results highlight the significant role of aliovalent dopants in regulating the phonon structure and suppressing the phonon propagation of semiconductors.

This result is achieved while maintaining the locality, the $SU(N)$ gauge invariance, and $\mathbb{Z}_N$ $1$-form gauge invariance, and we find that the manifest $1$-form gauge invariance plays the central role in our construction. This result gives the lattice regularized derivation of the mixed 't Hooft anomaly in pure $SU(N)$ Yang-Mills theory between its $\mathbb{Z}_N$ $1$-form symmetry and the $θ$ periodicity.

description: Mobile health is the "medical and public health practice supported by mobile devices, such as mobile phones, patient monitoring devices, personal digital assistants, and other wireless devices." For example, mobile apps (such as MASK-Air, Allergy.Monitor, Pollen, and others) have proven useful in the management of patients with allergic rhinitis. These apps can be used in the context of broader clinical decision support systems (CDSS) for enhancing allergy-related decisions and actions with pertinent, organized clinical knowledge and patient information to improve allergy care. A CDSS targeted to control rhinitis with drugs and other interventions guiding the patient in his/her self- and doctor-driven management is currently being produced and investigated by the MACVIA network. Another one, called @IT-2020, is targeted to support etiologic diagnostics and allergen immunotherapy (AIT) prescriptions for patients with seasonal allergic rhinitis. Intensive investigation is necessary to better define the advantages and limitations of mobile-health technology in allergology and establish guidelines for their proper use in daily practice in the context of a rapidly evolving European regulatory environment.

Both maps are part of Landscape Plan of the Region of Tuscany, which has been recently adopted. The evaluation of absolute theoretical intervisibility is obtained through the integration of viewshed of 117100 points distributed throughout the region in a regular grid; this integration highlights the Tuscan scenery great persistent horizons. The evaluation of weighted intervisibility assesses vice versa the probability of each point of the regional space to enter, with a significant role, into a scenery of an observer; this second processing, significantly more complex, is based on Analytic Hierarchy Process (AHP).

description: Generation and detection of entanglement is at the forefront of most quantum information technologies. There is a plethora of techniques that reveal entanglement on the basis of only partial information about the underlying quantum state, including entanglement witnesses. Superradiance refers to the phenomenon of highly synchronized photon emission from an ensemble of quantum emitters that is caused by correlations among the individual particles and has been connected by Dicke himself to the presence of multipartite entangled states. We investigate this connection in a quantitative way and discuss, whether or not signatures of superradiance from semiconductor nanolasers, manifesting themselves as a modification of the spontaneous-emission time, can be interpreted as a witness to detect entanglement in the underlying state of the emitters.

Academic Performance of Children with Social-Emotional Difficulties: Examining the Role of Self-Regulation
Creators: name: Montalbano, Cristin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Student with social-emotional difficulties are at increased risk for many adverse outcomes, including school dropout, serious mental health concerns, justice-involved behavior, and decreased quality of life. Thus, considerable attention needs to be directed toward identifying ways to bolster resilience and mitigate these risks for these students. Research suggests that self-regulation skills, including attention, inhibitory control and emotion regulation, are critical for success across a variety of areas including academic performance; however, there are many questions about which specific facets of self-regulation are most critical for academic performance more broadly as well as in specific areas like reading and mathematics. Moreover, most of the prior literature has focused on early childhood, overlooking the critical learning opportunities in early elementary school. Little is also known about the impact of these factors for higher risk students with clear social-emotional difficulties. As such, this study utilized an integrative theoretical framework of self-regulation to examine how self-regulation factors influence academic performance, specifically for early elementary students with social-emotional difficulties. The student sample consisted of 129 first and second grade students nominated by 68 teachers for a self-regulation intervention. Using baseline data collected as part of a federally-funded study, multilevel modeling was used to determine the extent to which various cognitive and emotional mechanisms of self-regulation were associated with teacher-rated academic performance, reading proficiency, and mathematics proficiency, after controlling for gender and socioeconomic status. Results indicated that attention, inhibitory control, and emotion regulation were significant predictors of teacher-rated academic performance. Attention was the only significant predictor of reading proficiency and inhibitory control was the only significant predictor of mathematics proficiency. Results also indicated that attention was the strongest predictor of teacher-rated academic performance and reading proficiency, whereas inhibitory control was the strongest predictor of mathematics performance. Socioeconomic status, one of the control variables, also accounted for significant variance in reading and mathematics proficiency as indicated by report card grades but not teacher-rated academic performance. These results add to the evidence that self-regulation is important for school success, and functions in a manner expected for early elementary students with social-emotional difficulties. Results suggest that both self-regulation and academic performance should be considered in interventions to help foster positive outcomes for students, particularly those with social-emotional difficulties who are most in need.

description: What research practices should be considered acceptable? Historically, scientists have set the standards and have been the main drivers of change in what constitutes acceptable research practices. However, there may be value in considering non-scientists’ perspectives and preferences, including research participants’. In this study, we will ask a sample of actual study participants, after their participation in a variety of minimal-risk studies, about how they would feel if some common research practices were applied to their own data. Participants will consider several research practices: p-hacking/cherry-picking results, selective reporting of studies, Hypothesizing After Results are Known (HARKing), committing fraud, conducting direct replications, sharing data, sharing methods, and publishing open access papers. Samples from both MTurk and college student populations will be used; a sample of 1,600 participants before exclusions will allow us to estimate the proportion of participants who hold favorable, indifferent, or unfavorable opinions towards each practice with at least +/- 3% precision. Pilot studies with smaller samples suggest research participants do have opinions and preferences about research practices, and are able to articulate them.
Thermodynamic Bound on the Asymmetry of Cross-Correlations

description: The principle of microscopic reversibility says that, in equilibrium, two-time cross-correlations are symmetric under the exchange of observables. Thus, the asymmetry of cross-correlations is a fundamental, measurable, and often-used statistical signature of deviation from equilibrium. Here we find a simple and universal inequality that bounds the magnitude of asymmetry by the cycle affinity, i.e., the strength of thermodynamic driving. Our result applies to a large class of systems and all state observables, and it suggests a fundamental thermodynamic cost for various nonequilibrium functions quantified by the asymmetry. It also provides a powerful tool to infer affinity from measured cross-correlations, in a different and complementary way to the thermodynamic uncertainty relations. As an application, we prove a thermodynamic bound on the coherence of noisy oscillations, which was previously conjectured by Barato and Seifert [Phys. Rev. E 95, 062409 (2017)]. We also derive a thermodynamic bound on directed information flow in a biochemical signal transduction model.

description: In this paper, we study module theoretic definitions of the Baer and related ring concepts. We say a module is s.Baer if the right annihilator of a nonempty subset of the module is generated by an idempotent in the ring. We show that s.Baer modules satisfy a number of closure properties. Under certain conditions, a torsion theory is established for the s.Baer modules, and we provide examples of s.Baer torsion modules and modules with a nonzero s.Baer radical. The other principal interest of this paper is to provide explicit connections between s.Baer modules and projective modules. Among other results, we show that every s.Baer module is an essential extension of a projective module. Additionally, we prove, with limited and natural assumptions, that in a generalized triangular matrix ring every s.Baer submodule of the ring is projective. As an application, we show that every prime ring with a minimal right ideal has the strong summand intersection property. Numerous examples are provided to illustrate, motivate, and delimit the theory.

description: We consider a planar heterostructure consisting of a normal metal in proximity to an antiferromagnetic insulator, with an interlayer exchange coupling between the metal and the insulator. The coupling to the two sublattices of the antiferromagnetic insulator is allowed to be asymmetric. An effective electron-electron interaction in the normal metal, mediated by antiferromagnetic magnons in the insulator, is derived to second order in the interlayer exchange coupling. Particular emphasis is placed on including analytically derived expressions for the effective interactions including Umklapp processes in the solutions to the superconducting gap equation. The gap equation is first solved at the critical temperature as an eigenvalue problem by linearizing the gap equation. The eigenvectors yield information on the symmetry of the superconducting gap at the onset of superconductivity, and we derive a phase diagram for the order parameter in this case. In the various regimes of the phase diagram, we find $p$-wave, $f$-wave, and $d$-wave superconductivity, with $p$-wave superconductivity in the dominant part of the phase diagram. Umklapp processes, that come into play with increasing size of the Fermi surface, yield $f$- and $d$-wave symmetries as the preferred symmetries when band filling approaches half filling. To investigate the stability of this order parameter symmetry as the temperature is lowered, we also consider the nonlinear gap equation at zero temperature. We conclude that the phase diagram and the symmetries of the superconducting order parameter essentially are left intact as the temperature is lowered to zero temperature.

description: Inverse design has revolutionized the field of photonics, enabling automated development of complex structures and geometries with unique functionalities unmatched by classical design. However, the use of inverse design in nonlinear photonics has been limited. In this work, we demonstrate quantum and classical nonlinear light generation in silicon carbide nanophotonic inverse-designed Fabry-Pérot cavities. We achieve ultra-low reflector losses while targeting a pre-specified anomalous dispersion to reach optical parametric oscillation. By controlling dispersion through inverse design, we target a second-order phase-matching condition to realize second- and third-order nonlinear light generation in our devices, thereby extending stimulated parametric processes into the visible spectrum. This first realization of computational optimization for nonlinear light generation highlights the power of inverse design for nonlinear optics, in particular when combined with highly nonlinear materials such as silicon carbide.

description: The essay aims to the outline the first thoughts flourished within an interdisciplinary research group of musicologists, musicians, historians and education experts, who are inquiring in both theoretical and practical ways to approach resonant landscapes: «The ear has to be sensitive to the marvellous world of sounds surrounding us» has been the first challenge faced by the group, starting from the first definition of “resonant landscape” by R.M. Schäfer (1977). Every landscape has its peculiar and unique sounds. They are determined by the perceptive ways, used by the individuals and the groups of people, as “resonant imprinting” able to connote a type of culture, able to contribute, together with other human expressions, to create the local identity. giving voice to these perceptions means to trigger paths of reflection and of listening education allowing to amplify a sensory channel that tends to be more and more neglected by the western culture.

description: Reverberant sound fields are often modeled as isotropic. However, it has been observed that spatial properties change during the decay of the sound field energy, due to non-isotropic attenuation in non-ideal rooms. In this letter, a model for the spatial coherence between two sensors in a decaying reverberant sound field is developed for rectangular rooms. The modeled coherence function depends on room dimensions, surface reflectivity and orientation of the sensor pair, but is independent of the position of source and sensors in the room. The model includes the spherically isotropic (diffuse) and cylindrically isotropic sound field models as special cases.

description: Spinful triplet Cooper pairs can be generated from their singlet counterparts available in a conventional superconductor (S) using two or more noncollinear magnetic moments, typically contributed by different magnets in a multilayered heterostructure. Here, we theoretically demonstrate that an S interfaced with a canted antiferromagnet (AF) harbors spinful triplet Cooper pairs capitalizing on the intrinsic noncollinearity between the two AF sublattice magnetizations. As the AF canting can be controlled by an applied field, our work proposes a simple bilayer structure that admits controllable generation of spin-triplet Cooper pairs. Employing the Bogoliubov-de Gennes framework, we delineate the spatial dependence of the spin-triplet correlations. We further evaluate the superconducting critical temperature as a function of the AF canting, which provides one experimental observable associated with the emergence of these triplet correlations.

description: Studies on climate change adaptation recognize the importance of agro-ecology based research for designing context-specific policies and programs to climate change. This study, therefore, applied a case-study approach to examine farmers’ preference for climate change adaptation strategies and the factors deriving their preference. Thus, households’ preference for five types of climate change adaptation strategies (multiple cropping, livestock, soil conservation, irrigation, and changing planting dates) is identified and the determinants of the preference are analyzed using Rank-Ordered Logit Model. The results indicated that multiple cropping is the most preferred and frequently applied adaptation strategy to climate change, while livestock production is the least.

Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Gravitational radiation and some global properties of spacetimes can only be unambiguously measured at future null infinity . This motivates the interest in reaching it within simulations of coalescing compact objects, whose waveforms are extracted for gravitational wave modelling purposes. One promising method to include future null infinity in the numerical domain is the evolution on hyperboloidal slices: smooth spacelike slices that reach future null infinity. The main challenge in this approach is the treatment of the compactified asymptotic region at future null infinity. Evolution on a hyperboloidal slice of a spacetime including a black hole entails an extra layer of difficulty, in part due to the finite coordinate distance between the black hole and future null infinity. Spherical symmetry is considered here as simplest setup still encompassing the full complication of the treatment along the radial coordinate. First, the construction of constant-mean-curvature hyperboloidal trumpet slices for Schwarzschild and Reissner-Nordström black hole spacetimes is reviewed from the point of view of the puncture approach. Then, the framework is set for solving hyperboloidal-adapted hyperbolic gauge conditions for stationary trumpet initial data, providing solutions for two specific sets of parameters. Finally, results of testing these initial data in evolution are presented.

The paper presents the experience of the Landscape Observatory of Canale di Brenta (Northeastern Italy), where in 2011-12 more than 1300 school children and their 80 teachers where involved in activities focused on knowledge, awareness and sharing of landscape and aimed to the reading of its complexity (denotative, connotative, interpretative and temporal reading) .

description: Ultracompact Minihalos (UCMHs) have been proposed as a type of dark matter sub-structure seeded by large-amplitude primordial perturbations and topological defects. UCMHs are expected to survive to the present era, allowing constraints to be placed on their cosmic abundance using observations within our own Galaxy. Constraints on their number density can be linked to conditions in the early universe that impact structure formation, such as increased primordial power on small scales, generic weak non-Gaussianity, and the presence of cosmic strings. We use new constraints on the abundance of UCMHs from pulsar timing to place generalised limits on the parameters of each of these cosmological scenarios. At some scales, the limits are the strongest to date, exceeding those from dark matter annihilation. Our new limits have the added advantage of being independent of the particle nature of dark matter, as they are based only on gravitational effects.

description: We have demonstrated a simple and accurate method for characterizing the capacitance of Graphene/n-Si Schottky junction solar cells (GSSCs) which embed the metal-oxide-semiconductor (MOS) capacitor. We measured two types of GSSCs, one with thermal annealing treatments (w-a) and one without (wo-a). It was found that the wo-a GSSC exhibits a two-step feature in the phase versus forward bias voltage relationship, which may be attributed to the presence of polymethyl methacrylate residues. By considering the capacitance of the MOS capacitor (Cmos) and its standard deviation, we successfully obtained the capacitance of the Schottky junction (CSch), and evaluated meaningful built-in potentials (Schottky barrier heights) which are 0.51V (0.78eV) and 0.47V (0.75eV) for the w-a and wo-a GSSCs, respectively, by the Mott-Schottky analysis. We also briefly discuss the relationship between CSch and the Nyquist and Bode plots, finding that the RC time constant decreases due to the subtraction of Cmos.

Stable cell-centered finite volume discretization for Biot equations
Creators: name: Nordbotten, Jan Martin
Publisher: name: arXiv
Year: 2015
Subjects: subject: Numerical Analysis (math.NA)
subject: FOS: Mathematics

description: In this paper we discuss a new discretization for the Biot equations. The discretization treats the coupled system of deformation and flow directly, as opposed to combining discretizations for the two separate sub-problems. The coupled discretization has the following key properties, the combination of which is novel: 1) The variables for the pressure and displacement are co-located, and are as sparse as possible (e.g. one displacement vector and one scalar pressure per cell center). 2) With locally computable restrictions on grid types, the discretization is stable with respect to the limits of incompressible fluid and small time-steps. 3) No artificial stabilization term has been introduced. Furthermore, due to the finite volume structure embedded in the discretization, explicit local expressions for both momentum-balancing forces as well as mass-conservative fluid fluxes are available. We prove stability of the proposed method with respect to all relevant limits. Together with consistency, this proves convergence of the method. Finally, we give numerical examples verifying both the analysis and convergence of the method.
Bulk-edge correspondence of Stiefel-Whitney and Euler insulators through the entanglement spectrum and cutting procedure

description: We propose an unconventional bulk-edge correspondence for two-dimensional Stiefel-Whitney insulators and Euler insulators, which are topological insulators protected by the $PT$ symmetry. We find that, although the energy spectrum under the open boundary condition is generally gapped, the entanglement spectrum is gapless when the Stiefel-Whitney or Euler class is nonzero. The robustness of the gapless spectrum for Stiefel-Whitney insulator can be understood through an emergent anti-unitary particle-hole symmetry. For the Euler insulators, we propose a conjecture, which is supported by our numerical calculation, that the Euler class is equal to the number of crossing in the entanglement spectrum, taking into account the degree of the crossings. We also discuss that these crossings of the entanglement spectrum are related to the gap closing points in the cutting procedure, which is the energy spectrum as the magnitude of the boundary hopping is varied.

Changes and Oral Microbiome Shifts in HIV+ Patients Following Periodontal Therapy
Creators: name: Schey, Karin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: The objective of this study was to compare clinical outcomes and oral microbiome changes following comprehensive dental care in HIV+ patients.      Twenty-seven HIV+ patients received periodontal treatment, oral hygiene instructions, caries control, and extraction of hopeless teeth. Systemic (viral load, CD4 counts, ART regimen) and oral clinical parameters (presence of caries, gingival and plaque indices) were measured at baseline (BL), 12-months (12M), and 24-months (24M) after therapy. Differences between clinical and microbial parameters between BL, to 12M, or 24M were determined.      Factors associated with changes in relative abundance of bacterial genera include smoking status, CD4 counts, and anti-retroviral mediation status. Several genera appear to be driving changes including Megasphaera, Kingella, Veillonella, and Prevotella. After one year of dental treatment, the oral microbiome shifts to a more HIV-negative, health-associated microbiome with increased alpha diversity of genera. This change in diversity plateaus in the second year of treatment in a well-maintained population.
L’altro paesaggio: il punto di vista dimenticato
Creators: name: Schürch, Dieter

description: This essay starts from the consideration that the perceived landscape is not only that we are used to think, of adult people which are involved in the landscape planning, but it is also the landscape of children, especially of babyhood. Their looking over the environment merit to reflect on question which has been till now the approach to landscape in its numerous and different declinations. The aim of essay is to describe “another landscape” and to propose guide lines to read through two communicating and linked levels: one at the interdisciplinary scale of sciences that manage with the territoriality, thus the child is an active part of territory; another one at the scale of child itself that through his eyes toward the world make possible building links that, later, will produce the adult landscape coherence.

description: The Gaia-ESO Survey is a public spectroscopic survey that has targeted $\gtrsim10^5$ stars covering all major components of the Milky Way from the end of 2011 to 2018, delivering its public final release in May 2022. Unlike other spectroscopic surveys, Gaia-ESO is the only survey that observed stars across all spectral types with dedicated, specialised analyses: from O ($T_\mathrm{eff} \sim 30,000-52,000$~K) all the way to K-M ($\gtrsim$3,500~K). The physics throughout these stellar regimes varies significantly, which has previously prohibited any detailed comparisons between stars of significantly different type. In the final data release (internal data release 6) of the Gaia-ESO Survey, we provide the final database containing a large number of products such as radial velocities, stellar parameters and elemental abundances, rotational velocity, and also, e.g., activity and accretion indicators in young stars and membership probability in star clusters for more than 114,000 stars. The spectral analysis is coordinated by a number of Working Groups (WGs) within the Survey, which specialise in the various stellar samples. Common targets are analysed across WGs to allow for comparisons (and calibrations) amongst instrumental setups and spectral types. Here we describe the procedures employed to ensure all Survey results are placed on a common scale to arrive at a single set of recommended results for all Survey collaborators to use. We also present some general quality and consistency checks performed over all Survey results.
