description: In this work, the capability of restricted Boltzmann machines (RBMs) to find solutions for the Kitaev honeycomb model with periodic boundary conditions is investigated. The measured groundstate (GS) energy of the system is compared and, for small lattice sizes (e.g. $3 \times 3$ with $18$ spinors), shown to agree with the analytically derived value of the energy up to a deviation of $0.09\%$. Moreover, the wave-functions we find have $99.89\%$ overlap with the exact ground state wave-functions. Furthermore, the possibility of realizing anyons in the RBM is discussed and an algorithm is given to build these anyonic excitations and braid them for possible future applications in quantum computation. Using the correspondence between topological field theories in (2+1)d and 2d CFTs, we propose an identification between our RBM states with the Moore-Read state and conformal blocks of the $2$d Ising model.

A hybrid quantum-classical approach to mitigating measurement errors

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: When noisy intermediate scalable quantum (NISQ) devices are applied in information processing, all of the stages through preparation, manipulation, and measurement of multipartite qubit states contain various types of noise that are generally hard to be verified in practice. In this work, we present a scheme to deal with unknown quantum noise and show that it can be used to mitigate errors in measurement readout with NISQ devices. Quantum detector tomography that identifies a type of noise in a measurement can be circumvented. The scheme applies single-qubit operations only, that are with relatively higher precision than measurement readout or two-qubit gates. A classical post-processing is then performed with measurement outcomes. The scheme is implemented in quantum algorithms with NISQ devices: the Bernstein-Vazirani algorithm and a quantum amplitude estimation algorithm in IBMQ yorktown and IBMQ essex. The enhancement in the statistics of the measurement outcomes is presented for both of the algorithms with NISQ devices.

description: The volume of tantalum versus pressure has been accurately measured up to 101 GPa by single-crystal x-ray diffraction, with helium as pressure transmitting medium. Slight deviation from previous static determinations is observed. Discrepancy with reduced shock-wave and ultrasonic data supports recent doubts about the calibration of the ruby pressure scale. Finally, first principle calculations of the literature show a positive curvature in $P(V)$ relative to the experimental data, even with a modified pressure scale.

description: Study performs food demand analysis in the case of Kosovo. Paper models food consumption behaviour using the HBS data for the period 2005-2012. Along with assessment of the non-parametric Engel curves, here we estimate complete demand system by using Quadratic Almost Ideal Demand System (QUAIDS). Elasticity estimates for five food bundles were amplified with demographic and expenditure controlling variables. Main results reveal that cereals and dairy products are perceived as inferior goods, while the meat, fruits and vegetables are regarded as normal goods. Consistency with the demand theory is affirmed when estimating price and expenditure elasticities. Exception is noticed in the case of cereals, depicting significantly higher own-price elasticity as well as negative expenditure elasticity. Such price sensitivity signals that Kosovo is undergoing transition of the food pattern from the traditional cereal-based diet towards the consumption of the high-value food such as meat and fish. Rising disposable income is found to play prominent role in fostering nutrition transition of the food pattern in Kosovo.
Effect of encoding processes on explicit and implicit remembering of melodies
Creators: name: Mungan, Esra
Publisher: name: American University
Year: 2023

description: This research aimed to explore memory for music within the transfer-appropriate processing (TAP) framework. According to TAP, a certain kind of initial processing is beneficial for later remembering if the type of memory test requires a similar type of processing. In Experiment 1, musicians and nonmusicians listened to a set of highly familiar melodies and applied different orienting tasks (OTs), two conceptual and two perceptual ones, while listening. The conceptual OTs comprised a mood judgment and a continuing the melody task, whereas the two perceptual OTs comprised a counting long notes and a contour tracing task. This was followed by an incidental recognition test. Nonmusicians and musicians recognized conceptually processed melodies better than perceptually processed ones, and musicians were more accurate than nonmusicians in their overall recognition performance. In Experiment 2, only the mood and counting OTs were used, and presentation modality (aural or audiovisual) was added as a new variable to see whether audiovisual processing would further emphasize the effect seen in Experiment 1. Furthermore, there was a perceptual identification test to see whether perceptual processing especially of audiovisually presented materials would lead to better identification compared to the other conditions. The data showed some trends in line with the predictions but none were statistically significant. The only significant effect was a main effect for musicianship in recognition accuracy. A presentation modality*musicianship interaction in the recognition data indicated that the audiovisual presentation mode had a beneficial effect for musicians and a detrimental effect for nonmusicians. Surprisingly, the OT effect observed in Experiment 1 was not replicated. Experiment 3 included only nonmusicians. Melody familiarity was added as a variable to see whether familiarity interacted with OT in recognition. Another goal of Experiment 3 was to see whether the OT effect observed in Experiment 1 could be "reobtained" when using a purely aural presentation mode again. Findings showed that highly familiar melodies were correctly recognized more than moderately and less familiar melodies, and furthermore, hit rates for mood-processed melodies were higher than for counting-processed melodies, given the melodies were highly familiar ones. The results are discussed within the TAP framework.

description: The objective of this paper is to analyse the production and export of Cocoa in Ghana. Concerns about declining output and export of cocoa in Ghana has prompted the necessity of this study. Given the significance of Ghana as the principal producer and exporter of cocoa and a major source of foreign earnings in the country, it is imperative to analyze the production and export trend of the industry. This study review cocoa production and export in Ghana over a 21 year period spanning from 1995 to 2016. Time series data were employed and these were collected from FOA database and other secondary sources from Literatures and books to process the data. We assessed the country’s production and export trend by using both empirical and descriptive approaches which were checked by multivariate statistical analysis. The results suggest that total cocoa production and export in Ghana both witnessed an average year-over- year increase of 5.3% and 5.7% respectively. In spite of these improvements observed, there is potential for further improvement and this can be achieved through government support to the subsector.

description: A study of high energy (43--68 MeV/nucleon) one-neutron removal reactions on a range of neutron-rich psd-shell nuclei (Z = 5--9, A = 12--25) has been undertaken. The inclusive longitudinal and transverse momentum distributions for the core fragments, together with the cross sections have been measured for breakup on a carbon target. Momentum distributions for reactions on tantalum were also measured for a subset of nuclei. An extended version of the Glauber model incorporating second order noneikonal corrections to the JLM parametrisation of the optical potential has been used to describe the nuclear breakup, whilst the Coulomb dissociation is treated within first order perturbation theory. The projectile structure has been taken into account via shell model calculations employing the psd-interaction of Warburton and Brown. Both the longitudinal and transverse momentum distributions, together with the integrated cross sections were well reproduced by these calculations and spin-parity assignments are thus proposed for $^{15}$B, $^{17}$C, $^{19-21}$N, $^{21,23}$O, $^{23-25}$F. In addition to the large spectroscopic amplitudes for the $\nu2$s$_{1/2}$ intruder configuration in the N=9 isotones,$^{14}$B and $^{15}$C, significant $\nu2$s$_{1/2}^2$ admixtures appear to occur in the ground state of the neighbouring N=10 nuclei $^{15}$B and $^{16}$C. Similarly, crossing the N=14 subshell, the occupation of the $\nu2$s$_{1/2}$ orbital is observed for $^{23}$O, $^{24,25}$F. Analysis of the longitudinal and transverse momentum distributions reveals that both carry spectroscopic information, often of a complementary nature. The general utility of high energy nucleon removal reactions as a spectroscopic tool is also examined.

Stationary quantum entanglement between a massive mechanical membrane and a low frequency LC circuit

description: We study electro-mechanical entanglement in a system where a massive membrane is capacitively coupled to a {\it low frequency} LC resonator. In opto- and electro-mechanics, the entanglement between a megahertz (MHz) mechanical resonator and a gigahertz (GHz) microwave LC resonator has been widely and well explored, and recently experimentally demonstrated. Typically, coupling is realized through a radiation pressure-like interaction, and entanglement is generated by adopting an appropriate microwave drive. Through this approach it is however not evident how to create entanglement in the case where both the mechanical and LC oscillators are of low frequency, e.g., around 1 MHz. Here we provide an effective approach to entangling two low-frequency resonators by further coupling the membrane to an optical cavity. The cavity is strongly driven by a red-detuned laser, sequentially cooling the mechanical and electrical modes, which results in stationary electro-mechanical entanglement at experimentally achievable temperatures. The entanglement directly originates from the electro-mechanical coupling itself and due to its quantum nature will allow testing quantum theories at a more macroscopic scale than currently possible.

Abstract

Decay is a universal process observed across physical, biological, and social systems. Traditionally, decay is interpreted as a purely entropic process—an inevitable degradation toward disorder. This paper presents a novel perspective through the lens of CODES (Chirality of Dynamic Emergent Systems), framing decay not as destruction but as a phase transition driven by structured resonance and energy redistribution. This framework redefines decay as a key adaptive mechanism that balances chaotic and ordered states, ensuring the emergence of new structures and patterns across scales.

We examine examples of decay in physical systems (radioactive decay, molecular dissociation), biological systems (cellular aging, ecological decomposition), and cosmological processes (stellar death, galactic evolution) to highlight the role of chirality and phase-locking in decay-driven transformation.

description: In a real-world setting, object instances from new classes can be continuously encountered by object detectors. When existing object detectors are applied to such scenarios, their performance on old classes deteriorates significantly. A few efforts have been reported to address this limitation, all of which apply variants of knowledge distillation to avoid catastrophic forgetting. We note that although distillation helps to retain previous learning, it obstructs fast adaptability to new tasks, which is a critical requirement for incremental learning. In this pursuit, we propose a meta-learning approach that learns to reshape model gradients, such that information across incremental tasks is optimally shared. This ensures a seamless information transfer via a meta-learned gradient preconditioning that minimizes forgetting and maximizes knowledge transfer. In comparison to existing meta-learning methods, our approach is task-agnostic, allows incremental addition of new-classes and scales to high-capacity models for object detection. We evaluate our approach on a variety of incremental learning settings defined on PASCAL-VOC and MS COCO datasets, where our approach performs favourably well against state-of-the-art methods.

description: By pursuing the goal to find new variables in the COROT field-of-view we characterised a sample of stars located in the lower part of the instability strip. Our sample is composed of stars belonging to the disk population in the solar neighbourhood. We found that 23% of the stars display multiperiodic light variability up to few mmag of amplitude. uvbyBeta photometry fixed most of the variables in the middle of the instability strip and high-resolution spectroscopy established that they have vsin i>100 km/s. The comparison with delta Sct stars in the whole Galaxy shows slightly different features, i.e., most delta Sct stars have a 0.05-mag redder (b-y)_0 index and lower vsin i values. Additional investigation in the open cluster NGC 6633 confirms the same incidence of variability, i.e., around 20%. The wide variety of pulsational behaviours of delta Sct stars (including unusual objects such as a variable beyond the blue edge or a rapidly rotating high-amplitude pulsator) makes them very powerful asteroseismic tools to be used by COROT. Being quite common among bright stars, delta Sct stars are suitable targets for optical observations from space.

description: The "square root" of the Dirac operator derived on the superspace is used to construct supersymmetric field equations. In addition to the recently found solution - a vector supermultiplet I demonstrate how a chiral supermultiplet follows as the solution. Both vector and chiral supermultiplets are shown to obey appropriate (massless) equations of motion. This procedure yields thus a complete set of fields and their equations necessary to construct renormalizable supersymmetric theories. The problem of masses and interaction is also discussed.

Life and death in the eastern woodlands: A bioarchaeological synthesis of seven Late Woodland period mortuary sites in Maryland
Creators: name: Kollmann, Dana Denise
Publisher: name: American University
Year: 2023

description: Human remains excavated from archaeological contexts have often played only marginal roles in our understanding of the past. Too frequently, human skeletons have been viewed as having little to contribute to the archaeological record or as such political headaches that they are not worth the trouble of removal and study. The emergent field of bioarchaeology is largely responsible for the recent contributions that have enabled a more thorough understanding of disease, demography, activity, subsistence, human adaptability, and population dynamics in antiquity. This study provides a detailed synthesis of biological, archaeological, and mortuary data for seven Late Woodland (A.D. 900--A.D. 1600) period sites in western Maryland and examines temporal, geographic, and cultural trends in health, disease, and mortuary practices. The goals of this study are to synthesize the biological, archaeological, and mortuary data for the described Late Woodland period sites in the Middle and Upper Potomac Valleys of what is today Maryland; establish demographic as well as morbidity and mortality profiles for the composite population and each cultural phase; evaluate the frequency and distribution of nutritional, pathological, and mechanical manifestations of stress on bone and teeth for the composite sample and each cultural phase; identify biological, environmental, and/or cultural sources of stress that contributed to the nutritional, pathological, and mechanical alterations evidenced in osseous tissues; and examine mortuary patterning through the assessment of burial associations and attributes for the composite sample and each Late Woodland cultural phase. Identified trends in health and disease indicate that most significant stressors experienced by the Late Woodland people of Maryland were those that were culturally based and related to the social and lifestyle alterations that accompanied the change from food collection to food production.

description: Lattice QCD calculations of nucleon form factors are restricted to discrete values of the Euclidean four-momentum transfer. Therefore, the extraction of radii typically relies on parametrizing and fitting the lattice QCD data to obtain its slope close to zero momentum transfer. We investigate a new method, which allows to compute the nucleon radius directly from existing lattice QCD data, without assuming a functional form for the momentum dependence of the underlying form factor. The method is illustrated for the case of the isovector mean square charge radius of the nucleon $\langle r^2_\mathrm{isov} \rangle$ and the quark-connected contributions to $\langle r^2_p\rangle$ and $\langle r^2_n \rangle$ for the proton and neutron, respectively. Computations are performed using a single gauge ensemble with $N_f=2+1+1$ maximally twisted mass clover-improved fermions at physical quark mass and a lattice spacing of $a=0.08\mathrm{fm}$.

Constraints on a Universal IMF from UV to Near-IR Galaxy Luminosity Densities

description: We obtain constraints on the slope of a universal stellar initial mass function (IMF) over a range of cosmic star-formation histories (SFH) using z=0.1 luminosity densities in the range from 0.2 to 2.2 microns. The age-IMF degeneracy of integrated spectra of stellar populations can be broken for the Universe as a whole by using direct measurements of (relative) cosmic SFH from high-redshift observations. These have only marginal dependence on uncertainties in the IMF, whereas, fitting to local luminosity densities depends strongly on both cosmic SFH and the IMF. We fit to these measurements using population synthesis and find the best-fit IMF power-law slope to be Gamma=1.15+-0.2 (0.5 < M/M_solar < 120). This slope is in good agreement with the Salpeter IMF slope (Gamma=1.35). A strong upper limit of Gamma<1.7 is obtained which effectively rules out the Scalo IMF due to its too low fraction of high-mass stars. This upper limit is at the 99.7% confidence level if we assume a closed-box chemical evolution scenario and 95% if we assume constant solar metallicity. Fitting to the H-alpha line luminosity density, we obtain a best-fit IMF slope in good agreement with that derived from broadband measurements. Marginalizing over cosmic SFH and IMF slope, we obtain (95% conf. ranges, h=1): omega_stars = 1.1-2.0 E-3 for the stellar mass density; rho_sfr = 0.7-4.1 E-2 M_solar/yr/Mpc^3 for the star-formation rate density, and; rho_L = 1.2-1.7 E+35 W/Mpc^3 for the bolometric, attenuated, stellar, luminosity density (0.09-5 microns). Comparing this total stellar emission with an estimate of the total dust emission implies a relatively modest average attenuation in the UV (<=1 magnitude at 0.2 microns).

description: The reform of mathematics education in the Unites States has been debated for many years. Although many mathematics educators concur about the objectives of reform, there is less agreement about the variety and efficacy of methodologies which can be used to improve classroom instruction and student learning. One such methodology, suggested by Boidy (1994), is to employ storytelling as an instructional strategy in teaching mathematics. According to Boidy, storytelling is a strategy in which children's literature is integrated into the mathematics curriculum. He asserts that storytelling can lead to higher student achievement, and more positive attitudes toward learning mathematics. In this study, storytelling, through the use of specific selections of children's literature, was implemented in two elementary schools, one private school located in Houston, Texas, and one public school located in Baltimore, Maryland. The total target population (N = 72) consisted of four third grade classes (two classes in each school). Thirty-six students were taught mathematics using storytelling and thirty-six students were taught mathematics using traditional methods. Improvement in the following instructional goals had been previously established for the period of the interventions: (1) two and three digit multiplication, and (2) two and three digit division. The primary hypothesis for this study was that the use of children's literature as a form of storytelling in elementary mathematics classrooms could be an effective method for teaching students to solve numerical and word problems, and should be considered as one of the methodologies that can be used in teaching mathematics. The purpose of this research was to demonstrate that a variety of methodologies could be employed to help students in mathematics. Of the thirty-six students in the pilot groups, 84.3% benefited from storytelling. All students were given pre-tests and post-tests to compare prior knowledge and skills learned. The pilot groups were also given attitude surveys, and participated in focus groups to obtain perceptions of storytelling. A one-way analysis of variance (ANOVA) was used to analyze significant differences between the pilot and control groups (p < .05). Regression analysis of the pre- and post-test scores was conducted to determine if storytelling improved mathematics learning and achievement. Responses to the attitude surveys were analyzed via frequencies. The findings indicated that the use of children's literature in storytelling is an effective instructional strategy to help elementary students become more interested in learning mathematics, improve skills in solving numerical and word problems, and increase achievement levels in mathematics.

description: A theoretical study of the structure formation observed very recently [Phys. Rev. Lett. 90, 128303 (2003)] in binary colloids is presented. In our model solely the dipole-dipole interaction of the particles is considered, electrohidrodynamic effects are excluded. Based on molecular dynamics simulations and analytic calculations we show that the total concentration of the particles, the relative concentration and the relative dipole moment of the components determine the structure of the colloid. At low concentrations the kinetic aggregation of particles results in fractal structures which show a crossover behavior when increasing the concentration. At high concentration various lattice structures are obtained in a good agreement with experiments.

description:
The extent to which work satisfaction, task satisfaction, suggestion quantity and suggestion quality may be affected by upward influence and reward in a suggestion program was investigated using 160 students as subjects. Locus of control and growth need strength were investigated in terms of their effects as personality moderators. Subjects offered suggestions during three trials for nine topics representing university problems. The percentage of suggestions accepted by a review committee was manipulated as four levels of an upward influence condition (0'/o, 25'/0, 50'/o and 75'/o). In addition, subjects were randomly assigned to either a no-reward or reward condition, in which subjects contingently received lottery tickets to win prizes based on the number of suggestions that were accepted by the review committee, The results indicated that (a) upward influence had an effect on task satisfaction when personality moderators were included in the analyses, and (b) reward and upward influence conditions had an effect on suggestion quantity and quality such that rewarded subjects in higher upward influence conditions offered more and better quality suggestions. Discussion focuses on this study's generalizability to the workplace and considerations for implementation of an employee suggestion program.

description: We investigate the computational issues related to the memory size in the estimation of quadratic covariation, taking into account the specifics of financial ultra-high-frequency data. In multivariate price processes, we consider both contamination by the market microstructure noise and the non-synchronicity of the observations. We formulate a multi-scale, flat-top realized kernel, non-flat-top realized kernel, pre-averaging and modulated realized covariance estimators in quadratic form and fix their bandwidth parameter at a constant value. This allows us to operate with limited memory and formulate this estimation as a streaming algorithm. We compare the performance of the estimators with fixed bandwidth parameter in a simulation study. We find that the estimators ensuring positive semidefiniteness require much higher bandwidth than the estimators without this constraint.

description: We examine the interplay of motility and information exchange in a model of run-and-tumble active particles where the particle's motility is encoded as a bit of information that can be exchanged upon contact according to the rules of AND and OR logic gates in a circuit. Motile AND particles become non-motile upon contact with a non-motile particle. Conversely, motile OR particles remain motile upon collision with their non-motile counterparts. AND particles that have become non-motile additionally "reawaken", i.e., recover their motility, at a fixed rate $μ$, as in the SIS (Susceptible, Infected, Susceptible) model of epidemic spreading, where an infected agent can become healthy again, but keeps no memory of the recent infection, hence it is susceptible to a renewed infection. For $μ=0$, both AND and OR particles relax irreversibly to absorbing states of all non-motile or all motile particles, respectively. The relaxation kinetics is, however, faster for OR particles that remain active throughout the process. At finite $μ$, the AND dynamics is controlled by the interplay between reawakening and collision rates. The system evolves to a state of all motile particles (an absorbing state in the language of absorbing phase transitions) for $μ>μ_c$ and to a mixed state with coexisting motile and non-motile particles (an active state in the language of absorbing phase transitions) for $μ
