description: Nonlinear optical properties (NLOPs) play a major role in photonics, electro-optics and optoelectronics, and other fields of modern optics. The design of new NLO molecules and materials has benefited from the development of computational tools to analyze the relationship between the electronic structure of molecules and its optical response. In this paper, we present a new means to analyze the response property through the partition of NLOPs in terms of orbital contributions (PNOC). This tool can be used to obtain a local representation of the NLOPs, providing a powerful visualization aid to connect the magnitude of the optical property with some parts of the molecule. Unlike other methods to analyze NLOPs, the PNOC decomposes the optical property into orbitals of the unperturbed system, furnishing this method with the ability to assess the performance of single- and multi-determinant electronic structure methods. PNOC can be also used to design small basis sets for an accurate description of large systems, saving a substantial amount of computer time for the calculation of optical properties.

description: We present new methodology and a case study in use of a class of Bayesian predictive synthesis (BPS) models for multivariate time series forecasting. This extends the foundational BPS framework to the multivariate setting, with detailed application in the topical and challenging context of multi-step macroeconomic forecasting in a monetary policy setting. BPS evaluates– sequentially and adaptively over time– varying forecast biases and facets of miscalibration of individual forecast densities for multiple time series, and– critically– their time-varying inter-dependencies. We define BPS methodology for a new class of dynamic multivariate latent factor models implied by BPS theory. Structured dynamic latent factor BPS is here motivated by the application context– sequential forecasting of multiple US macroeconomic time series with forecasts generated from several traditional econometric time series models. The case study highlights the potential of BPS to improve of forecasts of multiple series at multiple forecast horizons, and its use in learning dynamic relationships among forecasting models or agents.
A note on dissipation in helical turbulence

description: In helical turbulence a linear cascade of helicity accompanying the energy cascade has been suggested. Since energy and helicity have different dimensionality we suggest the existence of a characteristic inner scale, $ξ=k_H^{-1}$, for helicity dissipation in a regime of hydrodynamic fully developed turbulence and estimate it on dimensional grounds. This scale is always larger than the Kolmogorov scale, $η=k_E^{-1}$, and their ratio $η/ ξ$ vanishes in the high Reynolds number limit, so the flow will always be helicity free in the small scales.

description: Objective: Often, people with Subjective Cognitive Impairment (SCI), Mild Cognitive Impairment (MCI) and dementia are underwent to Electroencephalography (EEG) in order to evaluate through biological indexes the functional connectivity between brain regions and activation areas during cognitive performance. EEG recordings are frequently contaminated by muscle artifacts, which obscure and complicate their interpretation. These muscle artifacts are particularly difficult to be removed from the EEG in order the latter to be used for further clinical evaluation. In this paper, we proposed a new approach in removing muscle artifacts from EEG data using a method that combines second and high order statistical information. Subjects and Methods: In the proposed system the muscle artifacts of the EEG signal are removed by using the Independent Vector Analysis (IVA). The latter was formulated as a general joint Blind Source Separation (BSS) method that uses both second-order and higher order statistical information and thus takes advantage of both Independent Component Analysis (ICA) and Canonical Correlation Analysis (CCA). Diagonalization methods for IVA in the proposed system were reworked based on SCHUR decomposition offering a faster second order blind identification algorithm that can be used on time demanding applications. Results: The proposed method is evaluated in both simulated and real EEG data. To quantitatively examine the performance of the new method, two objective measures were adopted. The first measure is the Root Mean Square Error (RMSE) while the second is the Signal-to-noise-ratio (SNR). Conclusion: The proposed method overcomes with the need of removing muscle artifacts on both realistic simulated EEG data and brain activity from people with cognitive impairment.

description: Pumpkin is one of the crops grown in Trinidad and Tobago with a competitive advantage in the export market. A sector analysis conducted in 2005 identified the instability of cultivars leading to irregular shapes and sizes as one of the major weakness affecting the export market. A survey of producers/exporters revealed that the main characteristics required for export were smooth, cream/green coloured skin with thick, yellow/orange, sweet flesh. A number of fruits were collected and evaluated for the desired physical and quality characters. A breeding programme was developed using a Phenotypic Assortive Mating Design and Mass Selection to improve the uniformity of the varieties grown in Trinidad and Tobago. The characterization/evaluation data collected for this project included the following: skin colour (primary, secondary), flesh thickness, colour, flavour, moisture, texture, fruit shape, weight, fruit skin texture, diameter, length, skin hardness, cavity diameter, number of seeds/fruit, flesh moisture, total soluble solids and % dry matter. After six generations of breeding and selection the variety CES STARZ was developed with 79.7% uniformity with respect to fruit shape, skin and flesh colour in addition to improvement in sweetness and dryness.

If this decay conserves flavor SU(3), then it can be shown that this exotic meson must be a four-quark state ($q\bar q+q\bar q$) belonging to a flavor ${\bf10}\oplus{\bf\bar{10}}$ representation of SU(3). In contrast, the $π_1(1600)$ with a substantial decay mode into $η'π$ is likely to be a member of a flavor octet.

description: Papaya (Carica papaya) has a gelatinous sarcotesta surrounding the seed that can reduce germination due to inhibition of oxygen to the seed. However, removal of the sarcotesta allows the seeds to dry quicker and more exposure to oxygen. The viability of the clean seeds, sarcotesta removed at harvest, and held under refrigerated storage was not known. The objective of this research was to study the viability and germination of seven papaya lines, with seeds from 2006 to 2012. Seeds were imbibed in vitro for one week and a tetrazolium test for seed viability was applied. Seeds held in storage from 2006, 2008, and 2010, and fresh harvested seed from 2012 were planted (replicated) under greenhouse conditions. Germination was recorded over a 33-day cycle. There was great variability in germination between lines. For all papaya lines, the 2008 seed had the poorest germination, ranging from 10% to 60%. Papaya seed loose viability over time under refrigerated storage. This research was supported by USDA-Hatch and USDA-NIFA-lnsular Tropical Grant funds.

description: Introduction: Adequate empirical treatment should be established for treatment urinary tract infections, considering the prevalence of the most frequent microorganisms in each geographic area and their susceptibility to different antibiotics. The objective was to determine the microorganisms that cause episodes assist in a Regional Hospital, knowing their antibiotic susceptibility to establish empirical treatment. Methods: A descriptive-retrospective study was carried out based on the results of 12,204 urine cultures of the year 2,018. The overall empirical activity of the antibiotics tested was calculated, differentiating between episodes of the community and of hospitalized patients, adults and children. Results: E.coli was the most frequently isolated microorganism in all groups. The following in adults were: E.faecalis, K.pneumoniae and yeasts (8%). Regarding children, the following were E.faecalis and P.mirabilis. There was no difference in the activity of antibiotics against E.coli, in adults or in children, of the community or hospitalized, with sensitivity to fosfomycin and nitrofurantoin greater than 96%; at imipenem and piperacillin-tazobactam greater than 94% and third generation cephalosporins greater than 90%. However, the overall empirical activity, without distinction by microorganism, was for fosfomycin 77.96-80.60% in adults and 92.73-94.50% in children; to prevent 77.70-78.74% in adults and 92.36-91.28% in children; for piperacillin-tazobactam of 77.57-80.03% in adults and 89.09-94.04% in children; and for cefotaxime of 53.28-54.76% in adults and 68.73-74.77% in children. Conclusions: Fosfomycin, piperacillin-tazobactam and imipenem were the best option for empirical treatment without covering all episodes in adults.

 C o m m e n t: The above male may represent a distinct species. However, with only one male in somewhat poor condition available and since a male (in even worse condition) without additional punctures and longer elytra was found in Oros Pelion, too, the status of this material requires clarification based on more material, to rule out the possibility that the above male represents an aberrant specimen of Q. hellenicus. It is distinguished from the material of the described species treated in the present paper by shorter elytra, hind wings of reduced length, and by the morphology of the aedeagus, additionally also by smaller body size (Fig. 58) and shorter tarsi. The locality is situated in Oros Pelion [39°24'N, 23°02'E] (Greece: Thessalia) (Map 1) at an altitude of 400 m.

Body smaller (practically no overlap) (see measurements) and with very short tarsi (see measument HTaL and ratio HTiL/HTaL). Elytra (Fig. 8) very short (see measurement EL and ratio EL/PL). Hind wings present, but of reduced length.
 3: aedeagus (Figs 60-61, 57) smaller than in other species; median lobe somewhat resembling that of Q. hellenicus in lateral view, but broader in ventral view; paramere (Fig. 57) broad and rather short, with approximately 30 peg-setae arranged in a pair of distinctly separated clusters.

description: A study was conducted in split-plot design to determine the effect of single- and double-row plantings on the yield of four sweet potato cultivars (local names: 'Manager's Pudding', 'Caroline Lee', 'CBS 49' and 'CBS 32') commonly planted on the estates of the Barbados Agricultural Management Company Ltd. Cuttings were established on raised beds 5.5 ft apart. Single-rows consisted of cuttings placed on the centre of the beds with a spacing of 1 ft intra-row. For the double-rows, cuttings were established on both sides of the bed with 1.5 ft between rows and 1 ft intra-row. Shortly after establishment, the sweet potato was sprayed with Fusilade® (Fluazifop-p-butyl) using the recommended rate for the control of grass weeds. Mono-ammonium Phosphate was manually placed 6 inches away from all cuttings, after they were well established, at a rate of 100 lb per acre. Yield data showed that double-row planting of 'Caroline Lee', 'CBS 49', 'Manager's Pudding' and 'CBS 32' resulted in 21.3%, 31.4%, 16.7% and 16.8% significant decrease in average weight/ tuber, respectively, compared to single-row plantings. The total weight of tubers/ hole also decreased from single- to double-row planting ('Caroline Lee' - 35.7%, 'CBS 49' - 44.7%, 'Manager's Pudding' - 38.5% and 'CBS 32' - 43.5%) due to increased competition for resources in the smaller inter-row space. Smaller tubers were obtained from double-rows. These are suitable for the average household purchaser while the larger tubers from the single-rows are ideal for processors. Data extrapolation showed that the total yield/ acre increased from single- to double-row planting for each cultivar. As one moves from single- to doublerow planting, the total number of holes per acre doubles resulting in the expected increase in total yield. Total yield per acre (kg) increased by 28.7% for 'Caroline Lee'; 10.5% for 'CBS 49'; 23% for 'Manager's Pudding'; and 13.0% for the 'CBS 32' cultivar.

description: Rapid agricultural growth continues to be the key to poverty alleviation and overall economic development of Guyana. Agriculture accounts for about 20% of the Gross Domestic Product and is the source of livelihood for nearly 35% of the population. Research and extension have contributed significantly to the transformation of the Agricultural sector; however, the effectiveness of extension services is challenged in the areas of relevance, accountability and sustainability. It is becoming increasingly evident that public extension by itself can no longer respond to the multifaceted demands of farming systems. Present day agriculture is defined by key concepts of stability, sustainability, diversification and commercialization; therefore, there is urgent need for reorientation of the philosophy of extension from a technology transfer mode to a technology application mode. This paper examines the use of the Farming Systems Approach in agricultural extension and recommends the use of this approach to address issues of financial sustainability, farmers' participation in programme planning, researchextension linkages, marketing and value addition in the Guyana's Agriculture sector.

description: LeMo aims at exploring the impact of different interaction cues (visual, aural, proximity, annotation, awareness and so on) on collaborative music making in VR.Virtual Reality may provide a greater sense of community and more intuitive interactions in comparison to traditional media, and may also offer new opportunities human-computer interaction and human-to-human interaction.Whilst the potential of multi-user immersive virtual reality to facilitate social activities is well established, few VR applications currently exist in the field of music collaboration. Consequently, there are many open research questions on how to design VR user experiences to support Collaborative Music Making (CMM).I created a virtual music making tool called Let’s Move (LeMo), which is a social virtual environment for CMM. LeMo provides two people with a shared virtual reality musical interface with which they can make music together. The studies during my PhD focus on LeMo and are aiming at exploring the impact of different interaction cues (visual, aural, proximity, annotation, awareness and so on) on CMM.

description: The Guyana School of Agriculture (GSA) was established in the year 1963 by former President Dr. Cheddi Jagan. It became a state corporation in 1964 offering the Diploma in Agriculture and the Certificate in Agriculture Programmes, and graduated the first batch of 15 students in 1966. Agricultural diversification has become an important mechanism for economic growth by providing opportunities that facilitate technological advancement and demand driven government policy. In recognition of this and the consequences of the external environment that influence the process of agricultural diversification, the Guyana School of Agriculture generated a desire to build resilience into its academic programmes. In the year 1994 the Certificate in Forestry Programme was introduced, followed by the introduction of the Animal Health and Veterinary Public Health Programme in 2007 and the Certificate in Fisheries Programme was offered in 2008. The school over the years has graduated 2935 persons in different fields of agriculture and forestry celebrating 50 years of existence. This paper outlines the role of the Guyana School of Agriculture in addressing technical capacity building for agricultural diversification through the development of skills and capacities, as well as enhanced knowledge and information exchange between, the actors involved in innovation, including farmers and their organizations, agricultural research, education and training institutions, extension and advisory services institutions, and the researchers and professionals working in the agricultural sector of Guyana and the Caribbean. The School's programmes has not only allowed graduates to matriculate to local and international Universities and Collages but also their contribution to the sector has been remarkable with a geographic spread of 21 countries in the Caribbean and even in the African continent. This has been seen as a vital role in achieving robust and sustained growth in agriculture and therefore, GSA will continue to build on its strengths while seeking new opportunities for partnering and collaboration. This legacy would allow young people the opportunity to be involved in Agriculture and Forestry to realize their full potential and create wealth and at the same time preserve and conserve the environment for future generation

description: We consider general relativity with cosmological constant minimally coupled to electromagnetic field and assume that four-dimensional space-time manifold is the warped product of two surfaces with Lorentzian and Euclidean signature metrics. Einstein's equations imply that at least one of the surfaces must be of constant curvature. It means that the symmetry of the metric arises as the consequence of equations of motion (`spontaneous symmetry emergence'). We give classification of global solutions in two cases: (i) both surfaces are of constant curvature and (ii) the Riemannian surface is of constant curvature. The latter case includes spherically symmetric solutions (sphere S^2 with SO(3)-symmetry group), planar solutions (two-dimensional Euclidean space R^2 with IO(2)-symmetry group), and hyperbolic solutions (two-sheeted hyperboloid H^2 with SO(1,2)-symmetry). Totally, we get 37 topologically different solutions. There is a new one among them, which describes changing topology of space in time already at the classical level.

 Quedius (Raphirus) crnagoricus COIFFAIT, 1980: 38; nov.syn.
 C o m m e n t: The original description of Q. crnagoricus is based on a male holotype and five paratypes (three males and two females) from " Montenégro, Col de Čakor" deposited in the Coiffait collection (COIFFAIT 1980). However, the type material was looked for, but not found, by the curator in charge of the Coiffait collection at the MNHNP (TAGHAVIAN, e-mail 9 February, 2017). According to COIFFAIT (1980), this species is similar to Q. paradisianus in the shape of the aedeagus, but distinguished by infuscate metitibiae (sometimes also infuscate mesotibiae) and by entirely black elytra. As pointed out by ASSING (2016d), the coloration of the tibiae is variable in Q. paradisianus, and the elytra are mostly blackish in this species. Moreover, the shape of the aedeagus (COIFFAIT 1980: figures 1C-E) is identical to that of Q. paradisianus. Finally, the type locality of Q. crnagoricus is within the known range of Q. paradisianus. In consequence, there is no reasonable doubt that the type material of Q. crnagoricus is conspecific with Q. paradisianus.

description: Hybride Lernräume sind vereinfachend formuliert physische Räume, die durch den Einsatz von digitaler Technologie Lernszenarien erlauben, an denen sowohl in Präsenz als auch online teilgenommen werden kann. Dieser Beitrag stellt eine Evaluationsstudie einer 360°-basierten virtuellen Exkursion in einem hybriden Lernraum mit wand-füllender Projektion vor. Die virtuelle Exkursion wird durch einen Lehrenden geführt und dient als Vorbereitung für eine reale Exkursion zu der Kompostierungsanlage zwei Wochen später. Die Teilnehmenden der Exkursion (N=11) werden mit einem Fragebogen zu den lernpsychologischen Konstrukten Motivation, Emotion, soziale Präsenz und kognitive Belastung befragt. Die Ergebnisse werden mit denen der realen Exkursion verglichen. Neben mehrheitlich ähnlichen Werten werden auch einige Unterschiede gefunden, insbesondere für die soziale Präsenz. Insgesamt wird die Nutzung eines hybriden Lernraums für eine geführte 360°-basierte virtuelle Exkursion als positiv bewertet.

description: This paper presents a recommender system designed to match prospective students with study programs in Baden-Württemberg, Germany, streamlining the selection process by providing personalized recommendations based on user queries. Utilizing data from approximately 1,500 study programs and employing natural language processing and machine learning techniques, specifically the German fastText model for word embeddings, our system captures the semantic relationships between user queries and program descriptions. We evaluated the system’s performance using both manual test cases and automated validation methods. The manual evaluation involved subjective assessments by multiple raters, while the automated approach utilized self-supervised keyword-based approaches. The results demonstrate the system’s effectiveness in enhancing the study program selection process.

description: The Virgin Islands Beginning Farmer Training Program aims to ensure that there will be a sustainable new generation of farmers in the Virgin Islands. The project seeks to improve beginning farmer's income and enhance their potential for success. The target audience is beginning crop and small livestock farmers. These farmers are provided with information, skills, and techniques needed to make informed decisions to enhance the success of their farming enterprise. This is achieved through education and training in production and farm financial management to assist them in acquiring and successfully operating their farming agribusiness. It is expected that, as a result of the project, the target audience will successfully operate their farms while attracting other beginning farmers to operate sustainable agribusiness enterprises. The program provided training to 127 beginning farmers in the Virgin Islands. Special emphasis was placed on demonstrations and hands-on activities which enabled participants to successfully perform necessary farm-related tasks. Of those involved in the training program 60% are currently farming and plan to continue farming and increase the size and efficiency of their farming enterprise. The program has attracted the attention of other persons who are interested in participating in the program and getting involved in farming. The feedback from the persons involved has been very positive.

description: We present a theory for spin excitations in ferromagnetic metallic manganites and demonstrate that orbital fluctuations have strong effects on the magnon dynamics in the case these compounds are close to a transition to an orbital ordered state. In particular we show that the scattering of the spin excitations by low-lying orbital modes with cubic symmetry causes both the magnon softening and damping observed experimentally.

description: Nowadays, students have the option of using LLMs for assistance in solving homework assignments. Moreover, most LLMs, like ChatGPT, are also trained on large sets of source code and thus can be used to assist in programming exercises. In this paper, we present a case study based on data collected over the course of 1.5 semesters, where students of three programming-related courses were explicitly permitted to use such models while solving homework assignments. In a qualitative evaluation, we observe that there might be a difference between targeted requests for an answer to specific questions and requests for a complete solution from an LLM. Particularly, targeted requests might be pedagogical feasible and enhance the learning experience. Additionally, we discuss the potential of LLM applications in programming education, with a focus on the intermediate level and beyond.
A meta-learning recommender system for hyperparameter tuning: predicting when tuning improves SVM classifiers

description: For many machine learning algorithms, predictive performance is critically affected by the hyperparameter values used to train them. However, tuning these hyperparameters can come at a high computational cost, especially on larger datasets, while the tuned settings do not always significantly outperform the default values. This paper proposes a recommender system based on meta-learning to identify exactly when it is better to use default values and when to tune hyperparameters for each new dataset. Besides, an in-depth analysis is performed to understand what they take into account for their decisions, providing useful insights. An extensive analysis of different categories of meta-features, meta-learners, and setups across 156 datasets is performed. Results show that it is possible to accurately predict when tuning will significantly improve the performance of the induced models. The proposed system reduces the time spent on optimization processes, without reducing the predictive performance of the induced models (when compared with the ones obtained using tuned hyperparameters). We also explain the decision-making process of the meta-learners in terms of linear separability-based hypotheses. Although this analysis is focused on the tuning of Support Vector Machines, it can also be applied to other algorithms, as shown in experiments performed with decision trees.

description: We investigate the collective behavior of suspended thermoresponsive microgels, that expel solvent and subsequently decrease in size upon heating. Using a binary mixture of differently thermoresponsive microgels, we demonstrate how distinctly different gel structures form, depending on the heating profile used. Confocal laser scanning microscopy (CLSM) imaging shows that slow heating ramps yield a core-shell network through sequential gelation, while fast heating ramps yield a random binary network through homo-gelation. Here, secondary particles are shown to aggregate in a monolayer fashion upon the first gel, which can be qualitatively reproduced through Brownian dynamics simulations using a model based on a temperature-dependent interaction potential incorporating steric repulsion and van der Waals attraction. Through oscillatory rheology it is shown that secondary microgel deposition enhances the structural integrity of the previously formed single species gel, and the final structure exhibits higher elastic and loss moduli than its compositionally identical homo-gelled counterpart. Furthermore, we demonstrate that aging processes in the scaffold before secondary microgel deposition govern the final structural properties of the bigel, which allows a detailed control over these properties. Our results thus demonstrate how the temperature profile can be used to finely control the structural and mechanical properties of these highly tunable materials.
