description: A study was realized to determine the response of Taro (Colocasia esculenta var antiquorum) to spacing at two levels of fertilization at San Carlos, Costa Rica. Ten spacing in the range from 0,2496 to 0,8609 m2/plant were systematically arranged in split plots with fertilizer (50-50-50 kg/ha NPK) or without it. No interaction was found between fertilization and population densities. Fertilizer application increased yield 30%. As spacing was increased, the weight and the number of shoots pet plant were increased. Density of 0,246 m2/plant allowed for the highest net income.
Price Prediction for Airbnb Listings in New York

description: Predicting prices for Airbnb listings is a complex challenge, influenced by a variety of dynamic factors such as customer demand and location. Traditional pricing methods, including Comparative Price Analysis and manual appraisals, often fall short in optimizing revenue for hosts and providing competitive rates for guests. This underscores the necessity for an automated pricing system capable of accurately forecasting rental prices, enabling hosts to better assess return on investment (ROI) and attract potential guests with appealing rates. To tackle this issue, this project utilizes established machine learning algorithms to develop a predictive model specifically for Airbnb rental prices in New York. The methodology includes data acquisition, preprocessing, and the application of popular regression models. Initial data exploration revealed outliers in pricing, prompting a careful approach to their management. Among the regression algorithms tested, gradient boosting regression demonstrated the most promise, achieving a Root Mean Square Error (RMSE) of 33.49 and an R-squared value of 0.16, aligning with findings from related research. This paper details the development and evaluation of this predictive model, contributing to more effective pricing strategies for Airbnb hosts.
The distance to IC4499 from K-band photometry of 32 RR Lyrae stars

description: Single epoch K-band photometry of 32 RR Lyrae stars in the young galactic globular cluster IC4499 is presented. The mean magnitudes have been estimated using the K-band template light-curves of Jones, Carney and Fulbright (1996). We derive an independent estimate of the distance and reddening for the cluster based on the new -logP-[Fe/H] relation from Bono et al.(2003) which has a zero-point in agreement with the canonical LMC distance of (m-M)0 = 18.5. For an assumed metallicity of [Fe/H]=-1.65+-0.1 we find (m-M)0 = 16.47+-0.04+-0.06 (random and systematic errors respectively) and E(B-V)=0.24+-0.03 in good agreement with the findings of Walker and Nemec (1996) based on optical data. The distance estimate is very robust to uncertainties in the reddening estimate but naturally depends directly on the adopted zero-point of the -logP-[Fe/H] relation.

description: In this paper, we propose an architecture for FPGA emulation of mixed-signal systems that achieves high accuracy at a high throughput. We represent the analog output of a block as a superposition of step responses to changes in its analog input, and the output is evaluated only when needed by the digital subsystem. Our architecture is therefore intended for digitally-driven systems; that is, those in which the inputs of analog dynamical blocks change only on digital clock edges. We implemented a high-speed link transceiver design using the proposed architecture on a Xilinx FPGA. This design demonstrates how our approach breaks the link between simulation rate and time resolution that is characteristic of prior approaches. The emulator is flexible, allowing for the real-time adjustment of analog dynamics, clock jitter, and various design parameters. We demonstrate that our architecture achieves 1% accuracy while running 3 orders of magnitude faster than a comparable high-performance CPU simulation.

LARGE SCALE IN VIVO ZEBRAFISH SCREEN OF SMALL MOLECULE GLUTAMATE AGONISTS
Creators: name: O'Donnell, Ryan
Publisher: name: American University
Year: 2023

description: Excitotoxicity is a degenerative neurological condition involved in many common pathologies but is not well understood. Previous research suggests β-lactam compounds may offer neuroprotective abilities against excitotoxicity. This project aimed to screen, in vivo, a series of novel β-lactam compounds that exhibited in vitro neuroprotective effects. Zebrafish (Danio rerio) were used as a model organism in which excitotoxicity was induced with glutamate agonists and quantified via swimming behavior. Due to their size, rapid development, and high degree of brain homology relative to humans, zebrafish are an emerging model organism for neurological research. Results from this study demonstrated successful toxicology screening protocols for novel compounds, in addition to the feasibility of accurately quantifying zebrafish larvae movement. Results also suggest that the excitotoxicity model requires refinement for more substantial conclusions.

description: In this paper, the real scalar field equation in Schwarzschild-de Sitter spacetime is solved numerically with high precision. A method called polynomial approximation is introduced to derive the relation between the tortoise coordinate x and the radius r. This method is diﬀerent from the tangent approximation [1] and leads to more accurate result. The Nariai black hole is then discussed in details. We find that the wave function is harmonic only near the horizons as I. Brevik and B. Simonsen [1] found. Howerver the wave function is not harmonic in the region of the potential peak, with amplitude increasing instead. Furthermore, we also find that, when cosmological constant decreases, the potential peak increases, and the maximum wave amplitude increases.

description: We investigate the validity of the generalized second law of thermodynamics, applying Barrow entropy for the horizon entropy. The former arises from the fact that the black-hole surface may be deformed due to quantum-gravitational effects, quantified by a new exponent $Δ$. We calculate the entropy time-variation in a universe filled with the matter and dark energy fluids, as well as the corresponding quantity for the apparent horizon. We show that although in the case $Δ=0$, which corresponds to usual entropy, the sum of the entropy enclosed by the apparent horizon plus the entropy of the horizon itself is always a non-decreasing function of time and thus the generalized second law of thermodynamics is valid, in the case of Barrow entropy this is not true anymore, and the generalized second law of thermodynamics may be violated, depending on the universe evolution. Hence, in order not to have violation, the deformation from standard Bekenstein-Hawking expression should be small as expected.

description: Solar cabinet dryers appear suitable for use by small Caribbean farmers, many with farms less than 1 ha in size. Perishable products like sorrel, hot peppers, sweet potatoes and mango slices may be dried for safe storage. In a solar cabinet dryer of the multi-rack design, an overall drying efficiency of 25% can be expected. Crops can be dried in thin layers with loading densities of less than 5 kg/m2, in two days of fair weather. For the small farmers, with holdings ranging from 0.125 to 1 ha, and with 50% of their annual crop yield dried, dryers with cover areas ranging approximately from 3.8 m2 to 30.8 m2 respectively, will be adequate for a crop like sorrel. The minimum estimated cost of such dryers would correspondingly increase from US$75 to US$600.

description: Tomato genotypes have been field screened for fruit setting ability under high temperature (>30° day >21° night) and humidity conditions. Several genotypes have had good fruit set, but Cl l1d from the AVRDC in Taiwan is the most prominent heat tolerant source in current breeding lines. Fruit characters being selected are: large size, firmness, jointless stems, good shape, good color, even ripening, blossom-end smoothness, and no cracks. Disease resistance being incorporated include Fusarium wilt (F. oxysporum F. sp. lycopersici) races 1, 2 and 3, gray leaf spot (Stemphylium solani Weber), bacterial wilt (Pseudomonas solanacearum E. F. Smith), and bacterial spot (Xanthomonas campestris pv. vesicatoria). To further enhance fruit setting, a parthenocarpy gene (pat-2) has been incorporated into heat tolerant genotypes. In 1983, two such lines had yields equal to and greater than Cl l1d under high and low temperature conditions, respectively. This gene combination could result in horticulturally acceptable, multiple disease resistant breeding lines which will set fruit under both high and low temperatures and/or high humidity conditions not conducive to pollination.
Chiral Doubling of Heavy-Light Hadrons: BaBar 2317 MeV and CLEO 2463 MeV Discoveries

description: We point out that the very recent discoveries of BaBar (2317) and CLEO II (2460) are consistent with the general pattern of spontaneous breaking of chiral symmetry in hadrons built of heavy and light quarks, as originally suggested by us in 1992, and independently by Bardeen and Hill in 1993. The splitting between the chiral doublers follows from a mixing between the light constituent quark mass and the velocity of the heavy quark, and vanishes for a zero constituent quark mass. The general strictures of spontaneous chiral symmetry breaking constrain the axial charges in the chiral multiplet, and yield a mass splitting between the chiral doublers of about 345 MeV when the pion coupling to the doublers is half its coupling to a free quark. The chiral corrections are small. This phenomenon is generic and extends to all heavy-light hadrons. We predict the mass splitting for the chiral doublers of the excited mesons (D1,D2). We suggest that the heavy-light doubling can be used to address issues of chiral symmetry restoration in dense and/or hot hadronic matter. In particular, the relative splitting between D and D* mesons and their chiral partners decreases in matter, with consequences on charmonium evolution at RHIC.

description: Against the background of the islands' major marketing structures, notably intra-island, inter-island, and island-to-mainland, the paper discusses opportunities and constraints underlying food trade in the Eastern Caribbean. The discussion serves to provide a rationale for the existing food trade structures in the Eastern Caribbean. Finally, from the analysis, the paper suggests strategies for enhancing international marketing of food produce from the Eastern Caribbean. The strategies focus on production, pricing, distribution, and promotion of the food produce.

description: In 2017, an Atacama Large Millimeter/submillimeter Array (ALMA) high-frequency long baseline campaign was organized to test image capabilities with baselines up to 16 km at submillimeter (submm) wavelengths. We investigated image qualities using ALMA receiver Bands 7, 8, 9, and 10 (285-875 GHz) by adopting band-to-band (B2B) phase referencing in which a phase calibrator is tracked at a lower frequency. For B2B phase referencing, it is expected that a closer phase calibrator to a target can be used, comparing to standard in-band phase referencing. In the first step, it is ensured that an instrumental phase offset difference between low- and high-frequency Bands can be removed using a differential gain calibration in which a phase calibrator is certainly detected while frequency switching. In the next step, comparative experiments are arranged to investigate the image quality between B2B and in-band phase referencing with phase calibrators at various separation angles. In the final step, we conducted long baseline imaging tests for a quasar at 289 GHz in Band 7 and 405 GHz in Band 8 and complex structure sources of HL Tau and VY CMa at ~670 GHz in Band 9. The B2B phase referencing was successfully applied, allowing us to achieve an angular resolution of 14x11 and 10x8 mas for HL Tau and VY CMa, respectively. There is a high probability of finding a low-frequency calibrator within 5.4 deg in B2B phase referencing, bright enough to use an 8 s scan length combined with a 7.5 GHz bandwidth.

description: Post-harvest losses in fruits, vegetables, food crops and other perishable commodities, if effectively controlled, could feed millions of people now suffering from hunger and malnutrition in many parts of the world. Probably the heaviest losses occur in fruits and vegetables. Mature fruits and vegetables are highly susceptible to invasion by specific pathogenic micro-organisms. This is because they have a high water and nutrient content. After harvest they are no longer protected by the intrinsic factors which make them resistant during their development on the plant. Growth cracks and mechanical injuries during harvest, transport and storage are also responsible for the losses. The losses vary between various types of fruits and in different seasons of the year. The losses in the soft fruits during the summer months in a tropical region would be far more than in winters in the same area. To meet the world's current and future food demand many developmental programs aimed at increased production and population control have long been initiated all over the world. In the recent years, the potential to control the post-harvest losses has also been recognised as an effective means of increasing the capacity of current level of production 10 feed the existing and the ever increasing population. There is now a better appreciation of the problem both among producer and consumer alike.

description: In almost every way, web development has been getting better and better over the last ten years. During this time, a number of frameworks and libraries came out, which made it much easier and faster to make a web app. Over the last decade, the LAMP stack (Linux, Apache, MySQL, and PHP) and Java-based applications have dominated web development. It was challenging for a single developer to construct a web application by using these stacks because of how complex they were. As the field of web development matured, MERN-an acronym for "MongoDB," "Express," "React," and "Node JS"-emerged as the dominant stack in 2023. Due to the relative simplicity of the technologies comprising this stack, a single developer may effectively handle both the front-end and back-end of the application. MongoDB, which is a no?SQL database; Express, which is a framework of Node JS used in back-end development; React, which is a JavaScript library used in front-end development; and NodeJS, which is an environment for JavaScript; these are the components that make up the MERN stack

description: In the gravitational evolution of a cold infinite particle distribution, two-body interactions can be predominant at early times: we show that, by treating the simple case of a Poisson particle distribution in a static universe as an ensemble of isolated two-body systems, one may capture the origin of the first non-linear correlated structures. The developed power-law like behavior of the two-point correlation function is then simply related to the functional form of the time evolved nearest-neighbor probability distribution, whose time dependence can be computed by using Liouville theorem for the gravitational two-body problem. We then show that a similar dynamical evolution is also found in a large-scale ordered distribution, which has striking similarities to the case of a cosmological CDM simulation which we also consider.

description: CARDATS is an agricultural development project which offers a multi-disciplinary package of services to limited groups of small farmers in each of the OECS Member Stares within the Caribbean Community. The package of services includes assistance in farm planning, provision of inputs, production technology, and marketing. The modus operandi is based on the concept that sensible and effective coordination of all the links in the productivity chain - from planning, through production, to marketing - is essential for successful farming. Over the more than six years of its existence, the project's most persistent concern has been to improve the economic returns to the farmers with whom it has been associated. Since these farmers have, for the most part, been food crop growers, the production of vegetables and other root crops has received greatest attention in CARDATS' farm programming. CARDATS' programs, as described above, must obviously have an impact on associated rural communities. Similarly, rural situations influence, in some measure, the development processes undertaken in these programs. Within the CARDATS experience are many instances where farmer attitudes and responses to project initiatives are apparently conditioned by social and cultural influences. It is evident that these must be clearly understood and appreciated if meaningful and lasting small farmer development is to be achieved.

Basic network and node metrics are gathered. The main cluster is then partitioned into communities using the Girvan Newman algorithm based on edge betweenness. Many top artists were identified using centrality measures and the communities were found to be related to music style.

description: Sorghum (Sorghum bicolor [L.] Moench.) research activities at the Tropical Agriculture Research Station (TARS), Mayaguez, Puerto Rico, are described. In cooperation with the Texas Agricultural Experiment Station, 423 daylength insensitive lines from the Sorghum Conversion Program were developed. Numerous new collections were evaluated and classified. Other activities include the evaluation of new cytoplasms and their reactions when crossed to converted lines, the evaluation of grain and forage hybrids, the comparison of daylength sensitive versus daylength insensitive forage hybrids and the development of single and three-way hybrids. Newly developed single and three-way forage hybrids yield over 25 tons ha-1 of dry forage in 180 days. Sorghum populations developed, or in process of development, at TARS in cooperation with other scientists include: 1. populations with reduced hydrocyanic acid (HCN) potential; 2. populations of high yield potential; and 3. populations with increased resistance to common tropical diseases of sorghum.

description: It was known that for non-Hermitian topological systems due to the non-Hermitian skin effect, the bulk-edge correspondence is broken down. In this paper, by using one-dimensional Su-SchriefferHeeger model and two-dimensional (deformed) Qi-Wu-Zhang model as examples, we focus on a special type of non-Hermitian topological system without non-Hermitian skin effect-topological systems under non-Hermitian similarity transformation. In these non-Hermitian systems, the defective edge states and the breakdown of bulk-edge correspondence are discovered. To characterize the topological properties, we introduce a new type of inversion symmetry-protected topological invariant-total Z2 topological invariant. In topological phases, defective edge states appear. With the help of the effective edge Hamiltonian, we find that the defective edge states are protected by (generalized) chiral symmetry and thus the (singular) defective edge states are unstable against the perturbation breaking the chiral symmetry. In addition, the results are generalized to nonHermitian topological insulators with inversion symmetry in higher dimensions. This work could help people to understand the defective edge states and the breakdown of bulk-edge correspondence for non-Hermitian topological systems.

description: Aphid-borne virus diseases are the most important diseases of cucurbits in the West Indies that cause significant reduction in yield. Surveys of cucurbit farms throughout the West Indies revealed the presence of mosaic, existing in varying degrees of occurrence and severity, as the most predominant disease. The diseases were found to be caused by aphid-borne viruses, either in complexes or individually. Experiments to control the spread of these diseases with emulsion oils in Barbados revealed a six-fold reduction as compared with controls. The oil was applied with CP-3 knapsack sprayer (high volume) using cone jets to zucchini squash in a scheduled spray cycle. Droplet size emitted by the sprayer averaged 20 µm at 36 psi pressure. Rates of application averaged 7.5 ml/l of H2O. Reaping time has been prolonged to more than seven weeks. Fruit quality was improved and crop yield increased. There were no significant differences between disease spread in inoculated and uninoculated plots (P = .05).

description: An SO(10) grand unified model considered previously by the authors featuring lopsided down quark and charged lepton mass matrices is successfully predictive and requires that the lightest two right-handed Majorana neutrinons be nearly degenerate in order to obtain the LMA solar neutrino solution. Here we use this model to test its predictions for baryogenesis through resonant-enhanced leptogenesis. With the conventional type I seesaw mechanism, the best predictions for baryogenesis appear to fall a factor of three short of the observed value. However, with a proposed type III seesaw mechanism leading to three pairs of massive pseudo-Dirac neutrinos, resonant leptogenesis is decoupled from the neutrino mass and mixing issues with successful baryogenesis easily obtained.

description: The production of public goods like amenity value of the landscape, food security, preservation of rural communities and rural lifestyle, by agricultural sector is a subject that has been widely accepted by experts. However, in many policies and political analyses carried out, solely the production of private goods by the agricultural sector is paid attention and the important function of public goods production is ignored. Given the importance of multifunctional debate of agriculture in policies analysis, this study examined the effect of agricultural multifunctionality in the simulation of the agricultural production subsidies reduction effects using Computable General Equilibrium (CGE) model. Simulation results of the effects of agricultural production subsidies reduction in terms of the multifunctionality showed that current practices to support the agricultural sector is non-optimal according to agricultural production and welfare reduction and the optimal level of supports with and without multifunctional agriculture is different. The simulation results showed that the welfare effects of economic reforms in Iran in the agricultural sector in terms of the multifunctionality will be positive. This is on condition that the welfare effects of agricultural reform in terms of the multifunctionality of agriculture are negative.

Hydrology of Meadowood Special Recreation Management Area

description: Industrial development and urban sprawl can dramatically impact adjacent watersheds and associated streams. Meadowood Special Recreation Management Area (SRMA) is a piece of public land in Fairfax Va, owned by the Bureau of Land Management. Each of the SRMA’s three streams represents a different level of urban development (high, medium, and low). Water quality data were recorded weekly with measurements for pH, turbidity, nutrient concentrations, specific conductance, and dissolved oxygen. I hypothesized that differences in discharge and water quality among the three streams would reflect their level of urbanization. Thus, Giles Run, the most urbanized stream, would display the chemical characteristics of a heavily urbanized stream system and “flashier” flow. The specific conductance within Giles Run was significantly higher than that of the other two streams, which can be indicative of more urban water systems. Another finding that is important to note is the higher radon levels, indicating a greater degree of groundwater input, were observed in Thompson Creek when compared to the other streams in the park. The results of the study are aimed provide the managers of the park with a better understanding of the area’s hydrology.

description: The survival of the firms depends on the adoption of techniques and methods for encouraging learning among people. On other hand, it is necessary to have an attitude for interaction and endeavour in order for the learning to be built and conserved. Therefore, committed people in organizations have always been emphasized as a driving force of the extension and creation of learning. The aim of this study was to examine the impact of strategic learning practices on employees’ commitment in small and medium-sized sized enterprises (SMEs) engaged in agriculture and protein food production sectors in Guilan Province. The statistical society was composed of 650 key people of SMEs in agriculture and food sector in Guilan Province. Stratified sampling method was applied. Tseng’s standard questionnaire was used as main tool for data collection. The research is a practical study in terms of objective and a correlation-based descriptive studied in terms of data collection methodology. Descriptive statistics were used for data analysis and stepwise regression was used for inferential statistics. In inferential section, Pearson’s coefficient of correlation was used to examine the relationships between strategic learning methods and people’s commitment. Furthermore, stepwise regression was used to examine the impact of various aspects of strategic learning methods on people’s commitment. SPSS Software Package was applied for statistical analyses. It was found that strategic learning practices were significantly correlated with employees commitment. Based on the regression results, create system, strategic leadership and empower people were ranked as the first, second and third strongest factors influencing employees’ commitment, respectively.
Multifluid, Magnetohydrodynamic Shock Waves with Grain Dynamics II. Dust and the Critical Speed for C Shocks

description: This is the second in a series of papers on the effects of dust on multifluid, MHD shock waves in weakly ionized molecular gas. We investigate the influence of dust on the critical shock speed, v_crit, above which C shocks cease to exist. Chernoff showed that v_crit cannot exceed the grain magnetosound speed, v_gms, if dust grains are dynamically well coupled to the magnetic field. We present numerical simulations of steady shocks where the grains may be well- or poorly coupled to the field. We use a time-dependent, multifluid MHD code that models the plasma as a system of interacting fluids: neutral particles, ions, electrons, and various ``dust fluids'' comprised of grains with different sizes and charges. Our simulations include grain inertia and grain charge fluctuations but to highlight the essential physics we assume adiabatic flow, single-size grains, and neglect the effects of chemistry. We show that the existence of a phase speed v_phi does not necessarily mean that C shocks will form for all shock speeds v_s less than v_phi. When the grains are weakly coupled to the field, steady, adiabatic shocks resemble shocks with no dust: the transition to J type flow occurs at v_crit = 2.76 v_nA, where v_nA is the neutral Alfven speed, and steady shocks with v_s > 2.76 v_nA are J shocks with magnetic precursors in the ion-electron fluid. When the grains are strongly coupled to the field, v_crit = min(2.76 v_nA, v_gms). Shocks with v_crit < v_s < v_gms have magnetic precursors in the ion-electron-dust fluid. Shocks with v_s > v_gms have no magnetic precursor in any fluid. We present time-dependent calculations to study the formation of steady multifluid shocks. The dynamics differ qualitatively depending on whether or not the grains and field are well coupled.

description: We study the tunneling mechanism of nonlinear optical processes in solids induced by strong coherent laser fields. The theory is based on an extension of the Landau-Zener model with nonadiabatic geometric effects. In addition to the rectification effect known previously, we find two effects, namely perfect tunneling and counterdiabaticity at fast sweep speed. We apply this theory to the twisted Schwinger effect, i.e., nonadiabatic pair production of particles by rotating electric fields, and find a nonperturbative generation mechanism of the opto-valley polarization and photo-current in Dirac and Weyl fermions.

description: We use resolvent analysis to determine an unsteady active control setup to attenuate pressure fluctuations in turbulent supersonic flow over a rectangular cavity with a length-to-depth ratio of 6 at a Mach number of 1.4 and a Reynolds number based on cavity depth of 10,000. Large-eddy simulations (LES) and dynamic modal decomposition (DMD) of the supersonic cavity flow reveal the dominance of two-dimensional Rossiter modes II and IV. These predominantly two-dimensional vortical structures generate high-amplitude unsteadiness over the cavity through trailing-edge impingement and create oblique shock waves by obstructing the freestream. To disrupt the undesired formation of vortical structures, we introduce three-dimensional unsteady forcing along the cavity leading edge to generate streamwise vortical structures. Resolvent analysis with respect to the time-averaged base flow is leveraged to determine the optimal combination of forcing frequency and spanwise wavenumber. Instead of selecting the most amplified resolvent forcing modes, we seek the combination of control parameters that yields sustained amplification of the primary resolvent-based kinetic energy distribution over the entire length of the cavity. The sustained amplification is critical to ensure that the selected forcing input remains effective to prevent the formation of the large spanwise vortices. This resolvent-analysis-based flow control guideline is validated with a number of companion LES of the controlled cavity flows. The optimal control setup is verified to be the most effective in reducing the pressure root-mean-square level up to 52% along the aft and bottom cavity walls compared to the baseline cavity flow. The present flow control guideline derived from resolvent analysis should be applicable to flows that require the actuation input to remain effective over an extended region of interest.
