description: We propose an explicit small-signal graphene field-effect transistor (GFET) parameter extraction procedure based on a charge-based quasi-static model. The dependence of the small-signal parameters on both gate voltage and frequency is precisely validated by high-frequency (up to 18 GHz) on-wafer measurements from a 300 nm device. These parameters are studied simultaneously, in contrast to other works which focus exclusively on few. Efficient procedures have been applied to GFETs for the first time to remove contact and gate resistances from the Y-parameters. The use of these methods yields straightforward equations for extracting the small-signal model parameters, which is extremely useful for radio-frequency circuit design. Furthermore, we show for the first time experimental validation vs. both gate voltage and frequency of the intrinsic GFET non-reciprocal capacitance model. Accurate models are also presented for the gate voltage-dependence of the measured unity-gain and maximum oscillation frequencies as well as of the current and power gains.

description: We provide analytical expressions for classical and total trace-norm (Schatten 1-norm) geometric correlations in the case of two-qubit X states. As an application, we consider the open-system dynamical behavior of such correlations under phase and generalized amplitude damping evolutions. Then, we show that geometric classical correlations can characterize the emergence of the pointer basis of an apparatus subject to decoherence in either Markovian or non-Markovian regimes. In particular, as a non-Markovian effect, we obtain a time delay for the information to be retrieved from the apparatus by a classical observer. Moreover, we show that the set of initial X states exhibiting sudden transitions in the geometric classical correlation has nonzero measure.

Chromosomal rearrangements as barriers to genetic homogenization between archaic and modern humans
Creators: name: Rogers, Rebekah L.
Publisher: name: arXiv
Year: 2015
Subjects: subject: Genomics (q-bio.GN)
subject: FOS: Biological sciences

description: Chromosomal rearrangements, which shuffle DNA throughout the genome, are an important source of divergence across taxa. Using a paired-end read approach with Illumina sequence data for archaic humans, I identify changes in genome structure that occurred recently in human evolution. Hundreds of rearrangements indicate genomic trafficking between the sex chromosomes and autosomes, raising the possibility of sex-specific changes. Additionally, genes adjacent to genome structure changes in Neanderthals are associated with testis-specific expression, consistent with evolutionary theory that new genes commonly form with expression in the testes. I identify one case of new-gene creation through transposition from the Y chromosome to chromosome 10 that combines the 5' end of the testis-specific gene Fank1 with previously untranscribed sequence. This new transcript experienced copy number expansion in archaic genomes, indicating rapid genomic change. Among rearrangements identified in Neanderthals, 13% are transposition of selfish genetic elements, while 32% appear to be ectopic exchange between repeats. In Denisovan, the pattern is similar but numbers are significantly higher with 18% of rearrangements reflecting transposition and 40% ectopic exchange between distantly related repeats. There is an excess of divergent rearrangements relative to polymorphism in Denisovan, which might result from non-uniform rates of mutation, possibly reflecting a burst of TE activity in the lineage that led to Denisovan. Finally, loci containing genome structure changes show diminished rates of introgression from Neanderthals into modern humans, consistent with the hypothesis that rearrangements serve as barriers to gene flow during hybridization. Together, these results suggest that this previously unidentified source of genomic variation has important biological consequences in human evolution.

description: We report on the observations of the quasar NRAO 530 with the Event Horizon Telescope (EHT) on 2017 April 5-7, when NRAO 530 was used as a calibrator for the EHT observations of Sagittarius A*. At z=0.902 this is the most distant object imaged by the EHT so far. We reconstruct the first images of the source at 230 GHz, at an unprecedented angular resolution of $\sim$ 20 $μ$as, both in total intensity and in linear polarization. We do not detect source variability, allowing us to represent the whole data set with static images. The images reveal a bright feature located on the southern end of the jet, which we associate with the core. The feature is linearly polarized, with a fractional polarization of $\sim$5-8% and has a sub-structure consisting of two components. Their observed brightness temperature suggests that the energy density of the jet is dominated by the magnetic field. The jet extends over 60 $μ$as along a position angle PA$\sim -$28$^\circ$. It includes two features with orthogonal directions of polarization (electric vector position angle, EVPA), parallel and perpendicular to the jet axis, consistent with a helical structure of the magnetic field in the jet. The outermost feature has a particularly high degree of linear polarization, suggestive of a nearly uniform magnetic field. Future EHT observations will probe the variability of the jet structure on $μ$as scales, while simultaneous multi-wavelength monitoring will provide insight into the high energy emission origin.

description: Students of linguistics and psychology demonstrate that word choices people make convey information about their emotions and thereby their intentions. Focusing on theory from these related fields we test whether the emotional content of Supreme Court justices’ questions and comments made during oral arguments allow us to predict the decisions they make. Using aggregate data from all arguments between 1979 and 2008 and individual-level data from 2004 through 2008 we find justices’ use of more unpleasant language towards the attorney representing one side of a case reduces the probability that side will prevail on the merits, both in terms of individual justices’ votes and the overall case outcome.

Multi-soft theorems in Gauge Theory from MHV Diagrams
Creators: name: Georgiou, George
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this work we employ the MHV technique to show that scattering amplitudes with any number of consecutive soft particles behave universally in the multi-soft limit in which all particles go soft simultaneously. After identifying the diagrams which give the leading contribution we give the general rules for writing down compact expressions for the multi-soft factor of m gluons, k of which have negative helicity. We explicitly consider the cases where k equals 1 and 2. In N =4 SYM, the multi-soft factors of 2 scalars or 2 fermions forming a singlet of SU(4) R-symmetry, and m-2 positive helicity gluons are derived. The special case of the double-soft limit gives an amplitude whose leading divergence is 1/δ^2 and not 1/δas in the case of 2 scalars or 2 fermions that do not form a singlet under SU(4). The construction based on the analytic supervertices allows us to obtain simple expressions for the triple-soft limit of 1 scalar and 2 positive helicity fermions, as well as for the quadrapole-soft limit of 4 positive helicity fermions, in a singlet configuration.

description: The dual harmonic system has been widely used in high intensity proton synchrotrons to suppress the space charge effect, as well as reduce the beam loss. To investigate the longitudinal beam dynamics in the dual rf system, the potential well, the sub-buckets in the bunch and the multi-solutions of the phase equation have been studied theoretically. Based on these theoretical studis, the optimization of bunching factor and rf voltage waveform are made for the dual harmonic rf system in the upgrade phase of the CSNS/RCS. In the optimization process, the simulation with space charge effect is done by using a newly developed code C-SCSIM.
Galilean-Invariant XEFT

subject: FOS: Physical sciences

description: XEFT is a low-energy effective field theory for charm mesons and pions that provides a systematically improvable description of the X(3872) resonance. A Galilean-invariant formulation of XEFT is introduced to exploit the fact that mass is very nearly conserved in the transition D*0 --> D0 pi0. The transitions D*0 --> D0 pi0 and X --> D0 D0-bar pi0 are described explicitly in XEFT. The effects of the decay D*0 --> D0 gamma and of short-distance decay modes of the X(3872), such as J/psi --> pi+ pi-, can be taken into account by using complex on-shell renormalization schemes for the D*0 propagator and for the D*0 D0-bar propagator in which the positions of their complex poles are specified. Galilean-invariant XEFT is used to calculate the D*0 D0-bar scattering length to next-to-leading order. Galilean invariance ensures the cancellation of ultraviolet divergences without the need for truncating an expansion in powers of the ratio of the pion and charm meson masses.

The Relational Determinants of Legislative Outcomes: Strong and Weak Ties Between Legislators
Creators: name: Kirkland, Justin H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: In the repeated interactions of a legislative session, legislators develop working relationships that can be used in the pursuit of legislative goals. I develop a theory of influence diffusion across a legislative network of relations based on strategic actors building relationships in order to increase legislative success. Building on sociological theory initially developed by Granovetter, my research indicates that it is the weak ties between legislators that are the most useful in increasing legislative success. I test my theory using state legislative data from eight state legislatures, along with a second analysis of the U.S. House of Representatives. Empirical analysis provides consistent support for the notion that weak ties lead to legislative success.

description: The magnetic susceptibility, crystal and magnetic structures, and electronic structure of double perovskite Sr2ScOsO6 are reported. Using both neutron and x-ray powder diffraction we find that the crystal structure is monoclinic P21/n from 3.5 to 300 K. Magnetization measurements indicate an antiferromagnetic transition at TN=92K, one of the highest transition temperatures of any double perovskite hosting only one magnetic ion. Type I antiferromagnetic order is determined by neutron powder diffraction, with an Os moment of only 1.6(1) muB, close to half the spin-only value for a crystal field split 5d electron state with t2g^3 ground state. Density functional calculations show that this reduction is largely the result of strong Os-O hybridization, with spin-orbit coupling responsible for only a ~0.1 muB reduction in the moment.

description: An involution on a semigroup S (or any algebra with an underlying associative binary operation) is a function f:S->S that satisfies f(xy)=f(y)f(x) and f(f(x))=x for all x,y in S. The set I(S) of all such involutions on S generates a subgroup C(S)= of the symmetric group Sym(S) on the set S. We investigate the groups C(S) for certain classes of semigroups S, and also consider the question of which groups are isomorphic to C(S) for a suitable semigroup S.

description: Hydrogen, a simple and magic element, has attracted increasing attention for its effective incorporation within solids and powerful manipulation of electronic states. Here, we show that hydrogenation tackles common problems in two-dimensional borophene, e.g., stability and applicability. As a prominent example, a ladder-like boron hydride sheet, named as 2D ladder polyborane, achieves the desired outcome, enjoying the cleanest scenario with an anisotropic and tilted Dirac cone, that can be fully depicted by a minimal two-band tight-binding model. Introducing external fields, such as an electric field or a circularly-polarized light field can effectively induce distinctive massive Dirac fermions, whereupon four types of multi-field-driven topological domain walls hosting tunable chirality and valley indexes are further established. Moreover, the 2D ladder polyborane is thermodynamically stable at room temperature and supports highly switchable Dirac fermions, providing an ideal platform for realizing and exploring the various multi-field-tunable electronic states.

description: There is some evidence that speech aerodynamics follows the rules of a regulating system. The purpose of the present study was to assess how the speech system manages perturbations that produce "errors" within the system. Three experimental approaches were used to evaluate the physiological responses to an imposed change in airway resistance. The first involved subjects with varying degrees of velopharyngeal inadequacy. The second and third approaches involved noncleft subjects whose airway was perturbed by bleed valves and bite blocks during consonant productions. The pressure-flow technique was used to measure aerodynamic variables associated with the production of test consonants. The results of this study provide additional evidence that the speech system actively responds to perturbations in ways that tend to minimize a change in consonant speech pressures. The degree of success in stabilizing pressures appears to reflect the capability of the system to use whatever articulatory and respiratory responses are available.

Pitch discrimination and phase sensitivity in young and elderly subjects and its relationship to frequency selectivity
Creators: name: Peters, Robert W.
name: Moore, Brian C.J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: Frequency difference limens for pure tones (DLFs) and for complex tones (DLCs) were measured for four groups of subjects: young normal hearing, young hearing impaired, elderly with near-normal hearing, and elderly hearing impaired. The auditory filters of the subjects had been measured in earlier experiments using the notched-noise method, for center frequencies (fc) of 100, 200, 400, and 800 Hz. The DLFs for both impaired groups were higher than for the young normal group at all fc's (50-4000 Hz). The DLFs at a given fc were generally only weakly correlated with the sharpness of the auditory filter at that fc, and some subjects with broad filters had near-normal DLFs at low frequencies. Some subjects in the elderly normal group had very large DLFs at low frequencies in spite of near-normal auditory filters. These results suggest a partial dissociation of frequency selectivity and frequency discrimination of pure tones. The DLCs for the two impaired groups were higher than those for the young normal group at all fundamental frequencies (fo) tested (50, 100, 200, and 400 Hz); the DLCs for the elderly normal group were intermediate. At fo = 50 Hz, DLCs for a complex tone containing only low harmonics (1-5) were markedly higher than for complex tones containing higher harmonics, for all subject groups, suggesting that pitch was conveyed largely by the higher, unresolved harmonics. For the elderly impaired group, and some subjects in the elderly normal group, DLCs were larger for a complex tone with lower harmonics (1-12) than for tones without lower harmonics (4-12 and 6-12) for fo's up to 200 Hz. Some elderly normal subjects had markedly larger-than-normal DLCs in spite of near-normal auditory filters. The DLCs tended to be larger for complexes with components added in alternating sine/cosine phase than for complexes with components added in cosine phase. Phase effects were significant for all groups, but were small for the young normal group. The results are not consistent with place-based models of the pitch perception of complex tones; rather, they suggest that pitch is at least partly determined by temporal mechanisms.

description: In experiment 1 NoSo and NoS pi thresholds for a 500-Hz pure tone were obtained in a low-fluctuation masking noise and a high-fluctuation masking noise for six normal-hearing listeners. The noise bandwidth was 10 Hz. In agreement with previous investigations, the NoSo thresholds were lower in low-fluctuation noise than in high-fluctuation noise. For three listeners, NoS pi thresholds were similar for the two types of noise, while for the other three listeners, Nos pi thresholds were higher for low-fluctuation noise than for high-fluctuation noise. In experiment 2, the masker was created by amplitude modulating a 500-Hz pure tone by a 0-10-Hz low-pass noise. The degree of masker fluctuation was controlled by adjusting the average modulation depth (100%, 63%, 40%, and 25%). The signal was a 10-Hz-wide noise centered on 500 Hz. Results were similar to those of experiment 1: for the NoSo conditions, signal detection improved with decreasing degree of fluctuation, and for NoS pi conditions, the results were subject dependent. For three listeners, NoS pi thresholds were again similar in the two types of noise, while for the other three listeners, NoS pi thresholds were again higher in low-fluctuation noise than in high-fluctuation noise. The results showed that a high degree of masker fluctuation sometimes facilitates NoS pi detection. It is possible that the binaural detection mechanism utilizes the relatively good signal-to-noise ratios that occur in the low power or "dip" regions of fluctuating masker waveforms.

description: Farmland values are driven by a complex set of factors. Starting from the idea that land rent values may reflect several characteristics both internal and external to agricultural sector, the paper has implemented a hedonic model based on land rent values in the metropolitan area of Milan, Northern Italy, assessing the influence of climate, soil, territorial and farm variables on a sample of farms. The model is based on data at rent contract level, matched with data at farm and municipal scale retrieved from different sources. Results confirm that land rent prices are affected by some climate variables, along with territorial and farm characteristics.

description: The peri-urban agricultural landscape has a potential social value linked to the use of agricultural areas, as well as an agricultural-productive value. Multifunctionality has become fundamental in the sustainable management of urban and peri-urban agricultural areas. The paper describes the application of a decision-making support tool, based on a multi-methodological approach, for concerted management policies (Public bodies/farmers) in peri-urban agricultural areas. Three principles guide the proposal: Conservation of the historical landscape as heritage; Valorization of the social potentials of the landscape in the peri-urban context; Sustainable management, with a public-private partnership perspective.

description: The debate on climate change arose several concerns on the impacts of floods on agriculture and, consequently, on food security. At the same time, the European Floods Directive asks Members States to implement suitable measures to mitigate flood damage on economic activities, including farms. Still, while several analyses were developed to estimate potential flood damages on crops, a gap exists for livestock productions. The purpose of this study is to develop a conceptual model for the assessment of flood economic damages on dairy farms. Results propose a static and a dynamic model of farms recovery actions to re-establish the farming activity, which takes into account all farm components, as well as their interaction. Facing the destruction caused by floods, a first reaction of farmers could be closing the activity, with repercussion on this well-being as well as on farm workers’, and on the economy of rural areas. From this perspective, this study wants to provide a first methodological pathway to support farmers in restoring their activity.

description: We present results from a chiral soliton model calculation for the spectrum of baryons with a single heavy quark (charm or bottom) and non-zero strangeness. We treat the strange components within a three flavor collective coordinate quantization of the soliton that fully accounts for light flavor symmetry breaking. Heavy baryons emerge by binding a heavy meson to the soliton. The dynamics of this heavy meson is described by the heavy quark effective theory with finite mass effects included.

description: In this paper, we will deform the second and third quantized theories by deforming the canonical commutation relations in such a way that they become consistent with the generalized uncertainty principle. Thus, we will first deform the second quantized commutator and obtain a deformed version of the Wheeler-DeWitt equation. Then we will further deform the third quantized theory by deforming the third quantized canonical commutation relation. This way we will obtain a deformed version of the third quantized theory for the multiverse.

“Value portfolio”, value creation and multifunctionality: the case study of an Italian wine agritourism farm

description: Recent developments in the food market show a reemergence of short supply chain (SFSC) mechanisms that allow producers to directly sell to final consumers. Multifunctional farms are able to internalize some public value and transfer this value in their food produced as to increase income. As such, agritourism can be considered a pure form of SFSC in creating this added value. Using a case study of an Italian farm that produces both typical and fine wines, we aimed to analyze how agritourism creates added value. The SFSC and other opportunities were compared. From a multifunctional perspective, our other purpose was to identify the main drivers able to generate the “value portfolio” for the agritourist farmer. The results suggest that wide margins for creating value exist for on-farm distribution and that many aspects contribute to building the farmer’s “value portfolio”.

description: Healthcare workers experience high rates of workplace violence by patients. The highest risk of violence is seen in EDs, where patients first arrive to seek medical care. Because the ED is considered a high risk-for-violence setting, ED nurses are more likely to face violence than nurses working in other units. Aim: The aim of this quality improvement project was to revise the current workplace violence prevention protocol by implementing a new validated evidence-based risk-for-violence screening tool and evaluate its efficacy. Method: Using the plan-do-study-act framework, a validated risk-for-violence screening tool with a scoring system and assault prevention strategies were used and evaluated. Steps to implementing the project included the following: (1) adult and pediatric patients screened at the walk-in Triage for risk criteria for violence, (2) a scoring system based on low, moderate, and high risk for violence, (3) medical record tracking system flagged with a golden hand symbol to alert staff to moderate to high risk for violence, and (4) implementation of assault prevention strategies. Results: There was a total of 3857 screening tools completed using the QOVPRAO with 97% (n= 3759) of patients scoring at a low, 1% (n=65) moderate, and <1% (n=33) at high risk for violence. Fifty-nine percent of Triage nurses reported that the QOVPRAO adequately identified patients at risk for violence, 43% reported that the tool was easy to complete and quickly assessed risk, and 54% preferred to have the QOVPRAO tool replace the previous tool. Physical assaults on staff were recorded and tracked for a period of six weeks from the end of December 2023 to early February 2024, through a retrospective review of the hospital’s online incident report system. Patient-to-staff physical assaults during the project were zero. Conclusion: Screening for the risk of violence upon arrival and implementing strategies to prevent assaults present an opportunity to ensure and improve the safety of ED nurses. By implementing such preventive measures and providing support for staff, hospitals can create a safer working environment for ED nurses and improve overall patient care.

description: BACKGROUND: Patients with acute respiratory distress syndrome (ARDS) have a deficiency of surfactant. Surfactant replacement improves physiologic function in such patients, and preliminary data suggest that it may improve survival.

METHODS: We conducted a prospective, multicenter, double-blind, randomized, placebo-controlled trial involving 725 patients with sepsis-induced ARDS. Patients were stratified according to the risk of death at base line (indicated by their score on the Acute Physiological and Chronic Health Evaluation [APACHE III] index) and randomly assigned to receive either continuously administered synthetic surfactant (13.5 mg of dipalmitoylphosphatidylcholine per milliliter, 364 patients) or placebo (o.45 percent saline; 361 patients) in aerosolized form for up to five days.

RESULTS: The demographic and physiologic characteristics of the two treatment groups were similar at base line. The mean (+/- SD) age was 50 +/- 17 years in the surfactant group and 53 +/- 18 years in the placebo group, and the mean APACHE III scores at randomization were 70.4 +/- 25 and 70.5 +/- 25, respectively. Hemodynamic measures, measures of oxygenation, duration of mechanical ventilation, and length of stay in intensive care unit did not differ significantly in the two groups. Survival at 30 days was 60 percent for both groups. Survival was similar in the groups when analyzed according to APACHE III score, cause of death, time of onset and severity of ARDS, presence or absence of documented sepsis, underlying disease, whether or not there was a do-not-resuscitate order, and medical center. Increased secretions were significantly more frequent in the surfactant group; the rates of other complications were similar in the two groups.

CONCLUSIONS: The continuous administration of aerosolized synthetic surfactant to patients with sepsis-induced ARDS had no significant effect on 30-day survival, length of stay in the intensive care unit, duration of mechanical ventilation, or physiologic function.
Matera: city of nature, city of culture, city of regeneration. Towards a landscape-based and culture-based urban circular economy

description: Each city is a living organism with its own dynamics. Cities, as complex dynamic and adaptive systems, are able of self-organization/self-management. There are many causes of the decline of cities today (poverty, unemployment, etc.) that interdepend on the others in continuous retroactive processes. The general proposal of this paper refers to a key word: “regeneration” as revitalization of the activities in the perspective of the circular economy/city. The aim is to explore how an urban circular economy can be implemented through a cultural landscape-based approach, analysing the case study of Matera (Italy) and assuming the interdependence between a specific landscape and the circular economy/city models. The aim is to understand how to transform a millennial experience of underdevelopment into a dynamic development perspective.
