description: In this paper we define a new object, the momentum amplituhedron, which is the long sought-after positive geometry for tree-level scattering amplitudes in $\mathcal{N}=4$ super Yang-Mills theory in spinor helicity space. Inspired by the construction of the ordinary amplituhedron, we introduce bosonized spinor helicity variables to represent our external kinematical data, and restrict them to a particular positive region. The momentum amplituhedron $\mathcal{M}_{n,k}$ is then the image of the positive Grassmannian via a map determined by such kinematics. The scattering amplitudes are extracted from the canonical form with logarithmic singularities on the boundaries of this geometry.

description: We apply to the Random Field Ising Model at zero temperature (T= 0) the perturbative loop expansion around the Bethe solution. A comparison with the standard epsilon-expansion is made, highlighting the key differences that make the new expansion much more appropriate to correctly describe strongly disordered systems, especially those controlled by a T = 0 RG fixed point. This new loop expansion produces an effective theory with cubic vertices. We compute the one-loop corrections due to cubic vertices, finding new terms that are absent in the epsilon-expansion. However, these new terms are subdominant with respect to the standard, supersymmetric ones, therefore dimensional reduction is still valid at this order of the loop expansion.

description: We present a model of traffic flow, with rules that describe the behaviour of automated vehicles in an open system. We show first of all that the fundamental diagram of this system collapses to a point, where states of free and jammed traffic can coexist in phase space. This leads us to consider separately the roles of average velocities and densities as better descriptors of the actual state of the traffic. Next, we observe that the transition between free and jammed traffic as a function of the braking parameter R is different for high and low initial densities, in the steady state; it turns out to be 'smeared out' for low densities, a behaviour which is already portended by the transient behaviour of the system. Our results indicate strongly that, at least for such models, two effective temperatures (one related to R, and the other to the density) are needed to describe the global behaviour of this system in statistical mechanical terms. Analogies with granular flow are discussed in this context.

description: Over the past decade, the gravitational lensing of the Cosmic Microwave Background (CMB) has become a powerful tool for probing the matter distribution in the Universe. The standard technique used to reconstruct the CMB lensing signal employs the quadratic estimator (QE) method, which has recently been shown to be suboptimal for lensing measurements on very small scales in temperature and polarization data. We implement a simple, more optimal method for the small-scale regime, which involves taking the direct inverse of the background gradient. We derive new techniques to make continuous maps of lensing using this "Gradient-Inversion" (GI) method and validate our method with simulated data, finding good agreement with predictions. For idealized simulations of lensing cross- and autospectra that neglect foregrounds, we demonstrate that our method performs significantly better than previous quadratic estimator methods in temperature; at $L=5000-9000$, it reduces errors on the lensing auto-power spectrum by a factor of $\sim 4$ for both idealized CMB-S4 and Simons Observatory-like experiments and by a factor of $\sim 2.6$ for cross-correlations of CMB-S4-like lensing reconstruction and the true lensing field. We caution that the level of the neglected small-scale foreground power, while low in polarization, is very high in temperature; though we briefly outline foreground mitigation methods, further work on this topic is required. Nevertheless, our results show the future potential for improved small-scale CMB lensing measurements, which could provide stronger constraints on cosmological parameters and astrophysics at high redshifts.

description: This paper introduces the approach types of agricultural technology promotion we can choose in the process of new countryside construction, and there are mainly 6 types, namely government-domination-oriented approach, market-development-oriented approach, university (scientific research institution) -education-oriented approach, farmers' participation-oriented approach, direct-training-oriented approach and individual-service oriented approach including 20 models. The problems existing in the grass-root agricultural technology promotion in the process of new village construction are analyzed as follows: the awareness of innovation is not strong; scientific research, education, and promotion are disjointed; the construction of specific work system lags behind; me structure of promotion team is irrational, and the quality of promotion personnel is yet to be promoted; the cultural quality of farmers is low, and the cooperative organizations are not sound; the working conditions are poor, and the basic security is inadequate; the investment channel is simple and the supply amount is badly short; the methods of agricultural technology promotion do not adapt to the requirements of new situation. According to the characteristics and internal requirements of grass-roots agricultural technology promotion, we creatively design an overall working model, and put forward new measures from objective of grass-root agricultural technology promotion, service object, service content, organization work and scope, method, role of agricultural technology personnel and so on.

description: Due to the current rate of plastic manufacturing and inadequate management of plastic waste, plastics have emerged as a significant challenge and environmental threat worldwide. Microplastics (MPs), defined as plastic particles smaller than 5 mm, have gained global attention due to their widespread distribution, bioavailability, and potential health implications for humans. The marine environment, being the ultimate destination for various contaminants, including MPs, poses a particular concern as seafood contaminated with MPs can cause health risks since seafood plays a significant role as a major protein source globally. The Gold Coast is popular as a vacation and surfing destination in Australia and is characterised by high population density. Therefore, this research study focused on determining the occurrence of MPs in five selected seafood species popular in local fish markets in the Gold Coast, Australia. This thesis comprises four chapters. Chapter 1 provides the study's background and underscores its significance. Chapter 2 presents a comprehensive literature review analysing previous research on MPs, highlighting their toxic effects on human health, aquatic fauna, and the broader aquatic ecosystem. Furthermore, Chapter 2 discusses recent studies relevant to the present investigation and methodological advancements in MP research, including laboratory analysis techniques and quality assurance/quality control (QA/QC) measures. Chapter 3 constitutes the primary component of the thesis, the research study titled "Occurrence of Microplastics in Five Fresh Seafood Species Sourced from the Gold Coast, Australia", while Chapter 4 offers a general discussion and conclusion.

description: This paper concerns the economic assessment of a nonconventional technology to provide a cheap food and/or feed for many developing countries, using wasted resources, i.e. coastal arid areas irrigated directly with seawater to grow a halophyte crop(Salicornia-sos-7). It was cultivated for two successive years in Kuwait. The analysis showed that the harvested yield was 20 tons per hectare, which provided 12.42 MT of straw for sale and 1.7 MT of oil seeds for processing. Processed seeds of 1-hectare provide 425 kg of food oil and 1.1 MT of feed meal.Under Kuwait conditions, on per hectare basis, the total costs of production( fixed &variable costs)were $3088. However,simulation of this technology under a conventional developing country like Egypt with much less probability of sever sandy winds and less cost to adjust the irrigation network and much cheaper labor, much lower costs per hectare was achieved. Accordingly, the costs schedule would be $2903(investment costs), i. e. less than the current desert land reclamation costs in Egypt ($3000/ha)$1401 (variable costs)and 1588 (total costs of production).Under Kuwait conditions, the reached yield made a negative net farm income of 6.5% of the total costs of production. Under Egyptian condition, the same level of yield generated a positive gross margin of about 52% of the variable costs and a net farm income of 45% above the total costs of production. The ERR under Egyptian condition was 45% from investment in "Salicornia" production. Among several social benefits, such technology would introduce a much cheaper water resource. Under Kuwait condition costs was 1.2 cents/m3 of seawater, i.e. equivalent to 7% of the costs of brackish water production. Sheep-Hay Response Analysis showed that: At the current feed and livestock prices, to use salicornia hay is feasible up to 37% of the ration and the rest could be fulfilled from alfalfa hay. Cultivation of Salicornia at the wasted coastal area would save 1/3 of the berseem area in Egypt. This area could be devoted to produce 2000,000 tons of wheat. One hectare with livestock could provide sufficient livelihood for a family of five persons.

description: The $B \to κ\bar κ$ decays are investigated for the first time in the perturbative QCD formalism based on the $k_T$ factorization theorem, where the light scalar $κ$ is assumed as a two-quark state. Our numerical results and phenomenological analyses on the CP-averaged branching ratios and CP-violating asymmetries show that: (a) the $B_s^0 \to κ^+ κ^-$ and $B_s^0 \to κ^0 \bar κ^0$ decays have large decay rates around ${\cal O}(10^{-5})$, which could be examined by the upgraded Large Hadron Collider beauty and/or Belle-II experiments in the near future; (b) a large decay rate about $3 \times 10^{-6}$ appears in the pure annihilation $B_d^0 \to κ^+ κ^-$ channel, which could provide more evidences to help distinguish different QCD-inspired factorization approaches, even understand the annihilation decay mechanism; (c) the pure penguin modes $B_d^0 \to κ^0 \bar κ^0$ and $B_s^0 \to κ^0 \bar κ^0$ would provide a promising ground to search for the possible new physics because of their zero direct and mixing-induced CP violations in the standard model. The examinations with good precision from the future experiments will help to further study the perturbative and/or nonperturbative QCD dynamics involved in these considered decay modes.

description: Benzo(a)pyrene is a high-molecular-weight polycyclic aromatic hydrocarbon highly persistent in the environment as a biohazard. The present research emphasizes on rhizodegradation of BaP using bacterial isolates, Bacillus flexus S1I26 (NCBI accession no- KX692271), and Paenibacillus sp. S1I8 (KX602663) with plant Melia azedarach. The isolates produced surfactin type bio-surfactant with high emulsification index that could solubilize BaP efficiently. The extracted crude bio-surfactants could solubilize BaP up to 24.41%, which was higher than the efficiency of synthetic surfactant SDS (9.7%) but less than other synthetic surfactant, tweens 80 (42.79%). The isolates showed excellent degradation of BaP after 21 days in laboratory conditions where B. flexus S2I26 showed degradation of BaP up to 70.7% and isolates Paenibacillus sp. S1I8 showed degradation rate of 76.76% in a liquid medium. Pot trial experiment showed efficient rhizodegradation of BaP in the soil after 60 days in the rhizosphere of plant Melia azedarach. After application of S1I8 and S1I26, the rate of degradation was found to be much higher (87.42 and 86.08%) than in bulk (68.22%). Therefore, the results suggest that the bio-surfactant producing isolates could be a promising biodegradation tool for benzo(a)pyrene in soil and may be used for bioremediation of hydrocarbon contaminated sites.

description: The potential of three feedstocks: grain sorghum, sweet sorghum, and switchgrass for ethanol production in the top 26 counties of the Texas Panhandle Region is analyzed using yield and production costs of feedstock, processing cost of feedstock, final demand for ethanol, farm to wholesale marketing margin, and the derived demand price of feedstock. The calculated economic returns per acre of grain sorghum, sweet sorghum, and switchgrass are -$45.37, -$410.19, and -$150.17 respectively under irrigated condition and -$38.25, -$145.09, and -$29.04 respectively under dryland condition. The evaluation in this study demonstrates that ethanol production from grain sorghum, sweet sorghum, and switchgrass in the Texas Panhandle Region is not economically feasible given the current price for ethanol in Texas. This is consistent with the status of the ethanol industry in the Texas Panhandle.
Measurement and prediction of efficiency loss in LEDs

description: An order of magnitude improvement in power efficiency of light emitting diodes (LEDs) over incandescents makes them ideally suited for a variety of applications. GaInN LEDs, used to produce white light, exhibit a loss of efficiency with increased power. By measuring the efficiency of GaInN and GaAs LEDs we found losses beginning within their rated range. Linear regression allowed us to develop polynomial and power law models for efficiency loss. Models were evaluated using measurements at high power, with the power law model providing the best fit. Our results suggest further research should be conducted on temperature-related efficiency loss and its underlying causes.

description: This paper examined cost efficiency differences between rural hospitals participating in the Critical Access Hospital (CAH) Program and a group of non-converting, prospectively paid rural hospitals using both a two-stage semi-parametric approach as well as stochastic frontier analysis (SFA). CAHs receive Medicare cost-based reimbursement, in contrast with the rest of the hospitals reimbursed under Medicare prospective payment system (PPS). However, cost-based reimbursement has been associated with inefficiency in hospital operations and, consequently, concerns have been raised about the efficiency of CAHs. Results showed a positive and significant effect of CAH status on cost inefficiency under both model specifications suggesting that CAHs were less cost efficient than non-converting rural hospitals.

description: Trace detection of antibiotic ciprofloxacin by surface-enhanced Raman scattering (SERS) remains a challenge, because this compound is water-insoluble and amphoteric and it has no functional groups to combine with gold nanoparticles. Herein, ciprofloxacin was physically adsorbed on a self-assembly gold nanofilm for realizing quantitative SERS detection of ciprofloxacin in fish. A gold nanofilm containing ciprofloxacin spontaneously formed at the interface of gold colloids/n-hexane by vortex mixing in a few seconds without ethanol or other organic additives. The density of the gold nanoparticles on the interface which influences the SERS effect was controlled by varying the vortex mixing time and the volume of n-hexane. Furthermore, the proposed substrates with an enhancement factor of 2.7 × 106 were successfully applied for the determination of ciprofloxacin in fish samples with a linear range from 0.5 to 10.0 μg/mL and a detection limit of 0.19 μg/mL. The recovery measurements showed that the proposed SERS method had satisfactory precision and accuracy.

description: A recently posed question of Haggkvist and Scott's asked whether or not there exists a constant c such that if G is a graph of minimum degree ck then G contains cycles of k consecutive even lengths. In this paper we answer the question by proving that for k > 1, a bipartite graph of average degree at least 4k and girth g contains cycles of (g/2-1)k consecutive even lengths. We also obtain a short proof of the theorem of Bondy and Simonovits, that a graph of order n and size at least 8(k-1)n^{1 + 1/k} has a cycle of length 2k.

description: In many practical scenarios (e.g., finance, system reliability, etc.), it is often of interest to estimate a bivariate distribution and test for some desired association properties like positive quadrant dependent (PQD) or negative quadrant dependent (NQD). Often estimation and testing for PQD/NQD property are performed using copula models as it then eliminates the need for estimating marginal distributions. Many parametric copula families have been used that allow for controlling the PQD/NQD property by a finite dimensional parameter (often just real-valued) and the problem reduces to the straightforward estimation and testing for fixed dimensional parameter using standard statistical methodologies (e.g., maximum likelihood). This article extends such a line of work by dropping any parametric assumptions and provides a fully data-dependent automated approach to estimate a copula and test for PQD property. The estimator is shown to be large-sample consistent under a set of mild regularity conditions. Numerical illustrations based on simulated data are also provided to compare the performance of the proposed testing procedure with some available methods and applications to real case studies are also provided.

description: In the last decades we have witnessed the success of applications of Artificial Intelligence to playing games. In this work we address the challenging field of games with hidden information and card games in particular. Jass is a very popular card game in Switzerland and is closely connected with Swiss culture. To the best of our knowledge, performances of Artificial Intelligence agents in the game of Jass do not outperform top players yet. Our contribution to the community is two-fold. First, we provide an overview of the current state-of-the-art of Artificial Intelligence methods for card games in general. Second, we discuss their application to the use-case of the Swiss card game Jass. This paper aims to be an entry point for both seasoned researchers and new practitioners who want to join in the Jass challenge.

description: In this paper we present a new algorithm for Polynomial Linear System Solving (via evaluation/interpolation) with errors. In this scenario, errors can occur in the black box evaluation step. We improve the bound on the number of errors that we can correct, using techniques inspired by the decoding procedure of Interleaved Reed-Solomon Codes.

description: This paper measures the impact of bilateral exchange rates, the world agricultural GDP and third-country exchange rate volatilities (Yen/USD and Euro/USD) on the BRICS agricultural exports using a vector autoregressive (VAR) model. Two measures of volatility are used: the standard deviation and the coefficient of variation of the rates of change of the real exchange rates. We found that most variables are integrated of order two except the third-country exchange rate volatilities which are stationary and thus considered as exogenous in the VAR models. The causality between I(2) variables was tested using the modified Wald test introduced by Toda and Yamamoto (1995). We found that both volatilities (Yen/USD and Euro/USD) Granger cause Brazilian agricultural exports and that the Yen/USD causes Chinese agricultural exports.

description: This paper studies a zeta function of two complex variables (w, s) attached to an algebraic number field K, introduced by van der Geer and Schoof, which is based on an analogue of the Riemann-Roch theorem for number fields using Arakelov divisors. We mainly consider the case of the rational field Q, where for w = 1 one recovers the Riemann zeta function with the factors at infinity added. The analogue of the Riemann xi-function analytically continues to an entire function of two complex variables, and satisfies a functional equation holding w fixed and sending s to w-s. For real w the "critical line" is therefore Re(s) = w/2. For fixed nonnegative real w the zeros are confined to a vertical strip in s and have the same asymptotics as zeta zeros. For negative real w the function is positive real on the critical line, so has no zeros there. This phenomonon is associated to a positive convolution semigroup of infinitely divisible probability distributions, and the Khintchine canonical measure of this family is explicitly determined.

description: We summarize methods and expected accuracies in determining the basic low-energy SUSY parameters from experiments at future e$^+$e$^-$ linear colliders in the TeV energy range, combined with results from LHC. In a second step we demonstrate how, based on this set of parameters, the fundamental supersymmetric theory can be reconstructed at high scales near the grand unification or Planck scale. These analyses have been carried out for minimal supergravity [confronted with GMSB for comparison], and for a string effective theory.
