description: In 1971 Zel'dovich predicted that quantum fluctuations and classical waves reflected from a rotating absorbing cylinder will gain energy and be amplified. This key conceptual step towards the understanding that black holes may also amplify quantum fluctuations, has not been verified experimentally due to the challenging experimental requirements on the cylinder rotation rate that must be larger than the incoming wave frequency. Here we experimentally demonstrate that these conditions can be satisfied with acoustic waves. We show that low-frequency acoustic modes with orbital angular momentum are transmitted through an absorbing rotating disk and amplified by up to 30% or more when the disk rotation rate satisfies the Zel'dovich condition. These experiments address an outstanding problem in fundamental physics and have implications for future research into the extraction of energy from rotating systems.

description: We demonstrate that anyons on wire networks have fundamentally different braiding properties than anyons in 2D. Our analysis reveals an unexpectedly wide variety of possible non-abelian braiding behaviours on networks. The character of braiding depends on the topological invariant called the connectedness of the network. As one of our most striking consequences, particles on modular networks can change their statistical properties when moving between different modules. However, sufficiently highly connected networks already reproduce braiding properties of 2D systems. Our analysis is fully topological and independent on the physical model of anyons.

description: The dynamics of moving vortex lattice is considered in the framework of the time dependent Ginzburg - Landau equation neglecting effects of pinning. At high flux velocities the pinning dominated dynamics is expected to cross over into the interactions dominated dynamics for very clean materials recently studied experimentally. The stationary lattice structure and orientation depend on the flux flow velocity. The vortex lattice will have a different orientation for V>V_c. The two orientations can be desribed as motion "in channels" and motion of "lines of vortices perpendicular to the direction of motion. Although we start from the lowest Landau level approximation, corrections to conductivity and the vortex lattice energy dissipation from higher Landau levels are systematically calculated and compared to a recent experiment.

description: We have performed a pilot Chandra survey of an off-center region of the Coma cluster to explore the X-ray properties and Luminosity Function of normal galaxies. We present results on 13 Chandra-detected galaxies with optical photometric matches, including four spectroscopically-confirmed Coma-member galaxies. All seven spectroscopically confirmed giant Coma galaxies in this field have detections or limits consistent with low X-ray to optical flux ratios (fX/fR < 10^-3). We do not have sufficient numbers of X-ray detected galaxies to directly measure the galaxy X-ray Luminosity Function (XLF). However, since we have a well-measured optical LF, we take this low X-ray to optical flux ratio for the 7 spectroscopically confirmed galaxies to translate the optical LF to an XLF. We find good agreement with Finoguenov et al. (2004), indicating that the X-ray emission per unit optical flux per galaxy is suppressed in clusters of galaxies, but extends this work to a specific off-center environment in the Coma cluster. Finally, we report the discovery of a region of diffuse X-ray flux which might correspond to a small group interacting with the Coma Intra-Cluster Medium (ICM).

description: Recent years have seen mass casualties and severe property damage caused by wildland fires. With increasing housing development in natural-amenity-rich fire-prone areas, human activities not only exert intense pressures on local ecosystems, but also increase difficulties for wildland fire suppression. To cope with wildland fire threats and protect life and property from wildfire, a new California Natural Hazard Disclosure Law (California Civil Code Sec. 1103) went into effect in 1998. Information disclosure required by Sec. 1103 and its related laws is expected to enhance the efficiency of market allocation of land and developments in hazardous areas, making land price and development pattern better reflect the benefit and risk of living in the natural hazard zones. However, Troy and Romm (2004) suggested that the California Natural Hazard Disclosure Law had no effect for the overall population of fire-zone houses and did not stop overdevelopment in wildfire hazardous areas. In this paper, we expand a classic urban economics model to explore the impact of wildland fire-zone designations on housing development patterns in both a general equilibrium framework and a quantifiable manner. We conduct simulation studies to characterize the changes in urban development patterns and spatial profiles in response to the dynamics of wildland fire regimes. Our model and simulation results reveal the behaviors of residents and local governments and help us understand why Sec. 1103 and its related laws fail to stop over-development in wildfire hazardous areas.

description: Aim: To evaluate the effect of trigger day progesterone (P) levels on live birth in freeze-all cycles. Material and methods: Retrospective analysis of 1034 freeze-all female patients aged <38 years with single blastocyst transfers. Patients with (n = 268) or without (n = 766) preimplantation genetic test for aneuploidy (PGT-A) arm were further categorized into three subgroups based on trigger day P levels; low (<0.80 ng/ml), medium (0.8–1.49 ng/ml), and high (≥1.50 ng/ml). Results: Estradiol (E2) levels on trigger day, the number of oocytes retrieved and the number of mature oocytes increased significantly with increasing serum p values in cycles without and with PGT-A arms. Significant correlation was found between E2 levels on trigger day and serum P levels and between the number of total oocytes retrieved and serum P levels Live birth rates were similar in the three subgroups in without PGT-A arm (51%, 52.6%, and 51.5%, respectively; p = .922) and with PGT-A arm (55.1%, 55.1%, and 62.5%, respectively; p = .730). Multivariate regression analysis revealed that trigger day P levels were not significant for live birth. Conclusion: The proposal that trigger day progesterone elevation (PE) exerts a detrimental effect on oocyte and embryo competence has no clinical validity.

description: This paper investigates the determinants of academic achievement in basic education (grade 1-9) for a sample of children (aged 9-12 in 2000) from rural China. A set of instrumental variable generated by the Great Famine in China, 1958-1961, is used to instrument an error-ridden measure of child innate ability, the cognitive ability score of each sampled child. Empirical results indicate strong effects of family background variables such as household income and parental education. Father’s education has significantly positive effect on academic achievements for both boys and girls, while mother’s education only matters for girls. Consistent with the common findings in the literature, most of school quality variables do not have significantly positive effects on child academic achievements.

description: This study examined adoption of ten best management practices (BMPs) to control weed resistance to herbicides. Using data from a survey of 1,205 U.S. cotton, corn, and soybean growers, count data models were estimated to explain the total number of practices frequently adopted. Ordered probit regressions were used to explain the frequency of individual BMP adoption. Growers practicing a greater number of BMPs frequently (a) had more education, but less farming experience; (b) grew cotton, (c) expected higher yields relative to the county average; and (d) farmed in counties with a lower coefficient of variation (CV) for yield of their primary crop. Yield expectations and variability were significant predictors of the frequency of adoption of individual BMPs. Most growers frequently adopted the same seven BMPs. Extension efforts may be more effective if they target a minority of growers and the three practices with low adoption rates. Counties with a high yield CV would be areas to look for low BMP adoption.

description: A template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described. This novel approach is designed to suppress the increased out-of-time pileup contribution to the signal following the reduction of the accelerator bunch spacing from 50 to 25 ns at the start of Run 2 of the LHC. Execution of the algorithm is sufficiently fast for it to be employed in the CMS high-level trigger. It is also used in the offline event reconstruction. Results obtained from simulations and from Run 2 collision data (2015-2018) demonstrate a substantial improvement in the energy resolution of the calorimeter over a range of energies extending from a few GeV to several tens of GeV.

description: It is seen how to write the standardÊ form of the four partial differential equations in four unknowns of anisotropic thermoelasticity as a single equation in one variable, in terms of isothermal and isentropic wave operators. This equation, of diffusive type, is of the eighth order in the space derivatives and seventh order in the time derivatives and so is parabolic in character. After having seen how to cast the 1D diffusion equation into Whitham's wave hierarchy form it is seen how to recast the full equation, for uni-directional motion, in wave hierarchy form. The higher order waves are isothermal and the lower order waves are isentropic or purely diffusive. The wave hierarchy form is then used to derive the main features of the solution of the initial value problem, thereby bypassing the need for an asymptotic analysis of the integral form of the exact solution. The results are specialized to the isotropic case. The theory of generalized thermoelasticity associates a relaxation time with the heat flux vector and the resulting system of equations is hyperbolic in character. It is seen also how to write this system in wave hierarchy form which is again used to derive the main features of the solution of the initial value problem. Simpler results are obtained in the isotropic case.

description: Physicists have, hitherto, mostly adopted a frequentist conception of probability, according to which probability statements apply only to ensembles. It is argued that we should, instead, adopt an epistemic, or Bayesian conception, in which probabilities are conceived as logical constructs rather than physical realities, and in which probability statements do apply directly to individual events. The question is closely related to the disagreement between the orthodox school of statistical thought and the Bayesian school. It has important technical implications (it makes a difference, what statistical methodology one adopts). It may also have important implications for the interpretation of the quantum state.

description: Over the last few years, the prices of the main agricultural raw materials have been highly volatile. The situation is unprecedented, both in the magnitude of the upward and downward volatility observed, and in the number of agricultural commodities affected. Various factors are contributing to these contrasting shifts: the role of emerging countries, changing dietary habits, an increase in energy demand related to the boom in biofuels, adverse weather conditions and speculation. In this paper we try to capture long-term relationships between crop prices and crude oil price using a partial equilibrium and times series method. The study finds little empirical evidence that the crude oil price have a significant influence on the variation of major vegetable crops prices

description: Extracting a Construction Tree from potentially noisy point clouds is an important aspect of Reverse Engineering tasks in Computer Aided Design. Solutions based on algorithmic geometry impose constraints on usable model representations (e.g. quadric surfaces only) and noise robustness. Re-formulating the problem as a combinatorial optimization problem and solving it with an Evolutionary Algorithm can mitigate some of these constraints at the cost of increased computational complexity. This paper proposes a graph-based search space partitioning scheme that is able to accelerate Evolutionary Construction Tree extraction while exploiting parallelization capabilities of modern CPUs. The evaluation indicates a speed-up up to a factor of $46.6$ compared to the baseline approach while resulting tree sizes increased by $25.2\%$ to $88.6\%$.

description: We consider wake-like density fluctuations produced by cosmic strings at the quark-hadron transition in the early universe. We show that low momentum axions which are produced through the radiation from the axionic string at an earlier stage, may get trapped inside these wakes due to delayed hadronization in these overdense regions. As the interfaces, bordering the wakes, collapse, the axions pick-up momentum from the walls and finally leave the wake regions. These axions thus can produce large scale iso-curvature fluctuations. We have calculated the detailed profile of these axionic density fluctuations and discuss its astrophysical consequences.

description: The Chiral Magnetic Effect (CME) has been investigated as a new transport phenomenon in condensed matter. Such an effect appears in systems with chiral fermions and involves an electric current generated by a magnetic field by means of an "exotic" magnetic conductivity. This effect can also be connected with extensions of the usual Ohm's law either in magnetohydrodynamics or in Lorentz-violating scenarios. In this work, we study the classical propagation of electromagnetic waves in isotropic dispersive matter subject to a generalized Ohm's law. The latter involves currents linear in the magnetic field and implies scenarios inducing parity violation. We pay special attention to the case of a vanishing electric conductivity. For a diagonal magnetic conductivity, which includes the CME, the refractive index is modified such that it implies birefringence. For a nondiagonal magnetic conductivity, modified refractive indices exhibiting imaginary parts occur ascribing a conducting behavior to a usual dielectric medium. Our findings provide new insight into typical material properties associated with a magnetic conductivity.

description: Continuation of policy support for the U.S. corn ethanol industry will depend upon the greenhouse gas (GHG) effects of the industry, and its economic viability. The environmental and economic performance of ethanol plants is determined by the productivity of new technologies and, in addition, by the efficiency with which technologies are used (technical efficiency) and output and inputs are combined (economic efficiency). This study estimates the technical and economic efficiency of seven recently‐constructed ethanol plants in the North Central region of the US during 2006-2007. It uses nonparametric data envelopment analysis (DEA) and investigates both the drivers and implications of inefficiency differentials. In terms of drivers, results are consistent with the hypothesis that economic (profit) efficiency of productive units tends to be positively correlated with their size. Regarding implications results show that, on average, the maximum feasible reduction in Greenhouse Gases (GHG) emissions that can be achieved by these ethanol plants, when comparing across plants, is very limited (7,769 milligrams). We calculate that, by eliminating inefficiency, plants can achieve a 17% increase in returns over operating costs per gallon of ethanol produced, or about 12 cents a gallon. Therefore, plants can potentially increase their returns improving their economic viability. By enhancing economic viability, public policies can profoundly affect survival of this industry.

description: Abstract This paper investigates the competitiveness of small and medium-scale maize milling enterprises in South Africa from estimates of a translog stochastic cost frontier model. Results suggest that small and medium-scale maize mills in South Africa are cost-inefficient, operating at 59 percent and 30 percent higher cost than the best practice respectively. This implies that, on average, about 59 percent and 30 percent of the costs incurred by small and medium-scale maize mills respectively can be avoided without a reduction in maize meal output. Given this empirical estimates, if small and medium-scale maize milling enterprises in South Africa are able to reduce cost by 59 percent and 30 percent on average respectively, these mills could become competitive all things being equal, thus creating the much needed competition in the maize milling industry. Furthermore, results show that some mill-specific characteristics such as education, mill size, age of mill and location could contribute significantly to mill-level efficiency.

description: Biodiversity measurement is necessary to evaluate conservation alternatives and understand how to maximize biodiversity returns on conservation budgets. In the economics literature, most studies focus on species level diversity. Existing measures based on species' pairwise genetic differences do not perform optimally. This paper develops two new biodiversity measures within the same genetic framework. An axiomatic diagnosis for this class of measures is proposed and four biodiversity measures are then compared. Though the axiomatic comparison points towards a single "best" measure, it also indicates that the choice of measure should be dependent on the conservation problem at hand.

description: α-Thalassemia (α-thal) is assumed to be very prevalent in Bangladesh. We aimed to assess the prevalence of the disease in the country and provide a model for α-thal newborn screening in Bangladesh. We collected umbilical cord blood (UCB) samples from 413 unrelated newborns in Bangladesh. Demographic information, blood indices, osmotic fragility, serum iron (Fe), and zinc (Zn) levels were evaluated for all the subjects. All subjects underwent a polymerase chain reaction (PCR)-based diagnosis for α-thal status, followed by a multiplex gap-PCR-based identification of the deletion type present. Sixty-seven subjects had at least one α-thal deletion (16.22%). We observed that –α3.7 (rightward), – –SEA (Southeast Asian), –α4.2 (leftward), – –MED (Mediterranean) and – –THAI (Thailand) deletions were the most common α-globin deletions present in the country, with the –α3.7 (n = 37) and – –SEA (n = 18) being most prevalent. The osmotic fragility test (OFT) could predict the presence of α-thal deletions with over 98.0% sensitivity. Complete UCB count analysis revealed significant differences between healthy subjects and subjects with α-thal deletions. Although the iron level was almost the same (108.0 vs. 105.7 µg/dL), a reduced level of Zn (98.6 vs. 71.8 µg/dL, p

description: Prediction models of lattice thermal conductivity have wide applications in the discovery of thermoelectrics, thermal barrier coatings, and thermal management of semiconductors. kL is notoriously difficult to predict. While classic models such as the Debye-Callaway model and the Slack model have been used to approximate the kL of inorganic compounds, their accuracy is far from being satisfactory. Herein, we propose a genetic programming based Symbolic Regression approach for explicit kL models and compare it with Multi-Layer Perceptron neural networks and a Random Forest Regressor using a hybrid cross-validation approach including both K-Fold CV and holdout validation. Four formulae have been discovered by our symbolic regression approach that outperform the Slack formula as evaluated on our dataset. Through the analysis of our models' performance and the formulae generated, we found that the trained formulae successfully reproduce the correct physical law that governs the lattice thermal conductivity of materials. We also identified that extrapolation prediction remains to be a key issue in both symbolic regression and regular machine learning methods and find the distribution of the samples place a key role in training a prediction model with high generalization capability.

description: We report on the experimental characterization of energetic and dynamical instability, two mechanisms responsible for the breakdown of Bloch waves in a Bose-Einstein condensate interacting with a 1D optical lattice. A clear separation of these two regimes is obtained performing measurements at different temperatures of the atomic sample. The timescales of the two processes have been determined by measuring the losses induced in the condensate. A simple phenomenological model is introduced for energetic instability while a full comparison is made between the experiment and the 3D Gross-Pitaevskii theory that accounts for dynamical instability.

description: Advanced systems such as IoT comprise many heterogeneous, interconnected, and autonomous entities operating in often highly dynamic environments. Due to their large scale and complexity, large volumes of monitoring data are generated and need to be stored, retrieved, and mined in a time- and resource-efficient manner. Architectural self-adaptation automates the control, orchestration, and operation of such systems. This can only be achieved via sophisticated decision-making schemes supported by monitoring data that fully captures the system behavior and its history. Employing model-driven engineering techniques we propose a highly scalable, history-aware approach to store and retrieve monitoring data in form of enriched runtime models. We take advantage of rule-based adaptation where change events in the system trigger adaptation rules. We first present a scheme to incrementally check model queries in the form of temporal logic formulas which represent the conditions of adaptation rules against a runtime model with history. Then we enhance the model to retain only information that is temporally relevant to the queries, therefore reducing the accumulation of information to a required minimum. Finally, we demonstrate the feasibility and scalability of our approach via experiments on a simulated smart healthcare system employing a real-world medical guideline.

description: With the twelve-year long observations by {\sl Fermi}-LAT, we discover two pairs of spin-down state transitions of PSR J1124--5916, making it the second young pulsar detected to have such behaviors. PSR J1124--5916 shows mainly two states according to its spin-down rate evolution, the normal spin-down state and the low spin-down state. In about 80\% of the observation time, the pulsar is in the normal spin-down state, in which the spin-down rate decreases linearly and gives a braking index of $1.98\pm0.04$. The two transitions to the low spin-down state are in MJD 55183--55803 and MJD 56114--56398 respectively, with fractional amplitudes both $\sim0.4\%$. No significant difference between the $γ$-ray profiles of the two spin-down states is detected, which is similar to PSR B0540-69, the other young pulsar with state transition detected.

Investigation into the event-activity dependence of $Υ$(nS) relative production in proton-proton collisions at $\sqrt{s} = $ 7 TeV

description: The ratios of the production cross sections between the excited $Υ$(2S) and $Υ$(3S) mesons and the $Υ$(1S) ground state, detected via their decay into two muons, are studied as a function of the number of charged particles in the event. The data are from proton-proton collisions at $\sqrt{s} =$ 7 TeV, corresponding to an integrated luminosity of 4.8 fb$^{-1}$, collected with the CMS detector at the LHC. Evidence of a decrease in these ratios as a function of the particle multiplicity is observed, more pronounced at low transverse momentum $p_\mathrm{T}^{μμ}$. For $Υ$(nS) mesons with $p_\mathrm{T}^{μμ}$ $\gt$ 7 GeV, where most of the data were collected, the correlation with multiplicity is studied as a function of the underlying event transverse sphericity and the number of particles in a cone around the $Υ$(nS) direction. The ratios are found to be multiplicity independent for jet-like events. The mean $p_\mathrm{T}^{μμ}$ values for the $Υ$(nS) states as a function of particle multiplicity are also measured and found to grow more steeply as their mass increases.

description: Abstract: Posture recognition is a critical element of Bharathanatyam, a classical Indian dance form, characterized by intricate footwork, graceful movements, and expressive gestures. Automating posture recognition in Bharathanatyam images is essential for preserving this cultural art form while leveraging modern technological advancements. This survey examines existing methods and technologies for posture recognition, with a specific focus on Bharathanatyam poses. It provides an extensive review of datasets, techniques, and models, including traditional machine learning approaches like SVM and HOG features, as well as advanced deep learning models such as CNNs and LSTMs. The paper highlights the challenges in dataset preparation, feature extraction, and model accuracy due to variations in dancer attributes, lighting, and pose complexity. By systematically analyzing state-of-the-art techniques and their applications in related domains, this survey aims to bridge gaps and propose future directions for improving the precision and robustness of Bharathanatyam posture recognition systems.

description: The material presented here augments our rebuttal of comments by Sweatman, Powell, and West (hereafter SPW) on our comprehensive refutation of the Younger Dryas Impact Hypothesis (YDIH) published in Earth-Science Reviews. Owing to journal space limitations, we were unable to respond to their comments in a line-by-line fashion, instead we elected to focus on two themes that emerge from papers supporting the YDIH: 1) the conduct of science, and 2) recurrent misapprehensions by proponents.

The additional material consists of two tables. Table 1 presents a listing of critical comments by SPW and our replies, while Table 2 provides links to post-publication review comments on 33 papers supporting the YDIH that document problems and issues in those papers.

description: The hydroxyl radical (•OH) scavenging activities of Melatonin, an endogenously produced neurohormone and its related indolamines like N-acetyl tryptophan (NAT) and N-acetyl serotonin (NAS) have been investigated using density functional theory. The mechanism involves 4 steps: initial radical addition to position-3 of the indole ring, keto-amine to enol-imine tautomerization, cyclisation, and finally, addition of a second •OH leading to a cyclic end product. Incorporation of an explicit water molecule in tautomerization step leads to a significant reduction in the barrier of this step, so that the subsequent cyclisation step becomes rate-limiting. In agreement with the very high reactivity of •OH, the initial and final addition of •OH to indolamine are found to be barrierless. Radical adduct formed in the initial step was found to be very stable due to the extensive conjugation present in the substrate. Our calculations show that melatonin is the most effective radical scavenger among the three molecules chosen. NAS was found to exhibit antiradical property comparable to that of melatonin. In contrast to the general observation of reduced antioxidant activity of tryptophan, a non-natural derivative of tryptophan used here (NAT) is found to have good radical scavenging activity. This work further implies that non-natural derivatives of indolamines might as well be useful in the detoxification of free radicals as they exhibit almost comparable antioxidant efficiency as that of melatonin.

description: Online recommendation systems make use of a variety of information sources to provide users the items that users are potentially interested in. However, due to the openness of the online platform, recommendation systems are vulnerable to data poisoning attacks. Existing attack approaches are either based on simple heuristic rules or designed against specific recommendations approaches. The former often suffers unsatisfactory performance, while the latter requires strong knowledge of the target system. In this paper, we focus on a general next-item recommendation setting and propose a practical poisoning attack approach named LOKI against blackbox recommendation systems. The proposed LOKI utilizes the reinforcement learning algorithm to train the attack agent, which can be used to generate user behavior samples for data poisoning. In real-world recommendation systems, the cost of retraining recommendation models is high, and the interaction frequency between users and a recommendation system is restricted.Given these real-world restrictions, we propose to let the agent interact with a recommender simulator instead of the target recommendation system and leverage the transferability of the generated adversarial samples to poison the target system. We also propose to use the influence function to efficiently estimate the influence of injected samples on the recommendation results, without re-training the models within the simulator. Extensive experiments on two datasets against four representative recommendation models show that the proposed LOKI achieves better attacking performance than existing methods.
