description: A carcinicultura brasileira é desenvolvida em 997 fazendas, sendo 71,41% enquadrados na categoria de pequenos aqüicultores. Apesar da participação do país ainda ser pequena comparativamente aos principais produtores mundiais de camarão cultivado, existem interessantes perspectivas de expansão da atividade. Nas últimas décadas foram realizadas experiências com várias espécies de camarão em cativeiro no Brasil, sendo que uma das que apresentou maior destaque, foi o camarão exótico Litopenaeus vannamei (Boone, 1931). O Estado do Pará, por ser um berçário natural de várias espécies de camarão marinho e por ter sua costa caracterizada por estuários, ideais para o cultivo do camarão, vem se constituindo numa área potencial para a implantação de novos projetos com esta espécie. O trabalho analisa a cadeia produtiva da carcinicultura no Estado do Pará, enfatizando a espécie Litopenaeus vannamei. O instrumental teórico utilizado para a análise competitiva foi o modelo das cinco forças de Michael Porter, consubstanciado na ameaça de entrantes potenciais, dos concorrentes existentes, de produtos substitutos, do poder dos fornecedores e dos clientes. O principal objetivo desta pesquisa é caracterizar o ambiente de ameaças e oportunidades que permeia a cadeia produtiva e mostrar que a pesca extrativa está atingindo um ponto de saturação para várias espécies,enquanto a aqüicultura oferece, tanto para o produtor quanto para o consumidor, a segurança de oferta no espaço e no tempo, assim como promove o desenvolvimento sustentável.

description: The kinetic behavior of a phase field model of electrochemistry is explored for advancing (electrodeposition) and receding (electrodissolution) conditions in one dimension. We described the equilibrium behavior of this model in [J. E. Guyer, W. J. Boettinger, J.A. Warren, and G. B. McFadden, ``Phase field modeling of electrochemistry I: Equilibrium'', cond-mat/0308173]. We examine the relationship between the parameters of the phase field method and the more typical parameters of electrochemistry. We demonstrate ohmic conduction in the electrode and ionic conduction in the electrolyte. We find that, despite making simple, linear dynamic postulates, we obtain the nonlinear relationship between current and overpotential predicted by the classical ``Butler-Volmer'' equation and observed in electrochemical experiments. The charge distribution in the interfacial double layer changes with the passage of current and, at sufficiently high currents, we find that the diffusion limited deposition of a more noble cation leads to alloy deposition with less noble species.

description: We examined cross-sectional associations of sleep measures with central retinal artery equivalent (CRAE) and central retinal vein equivalent (CRVE) and investigated whether sex and race/ethnicity modified these associations. Participants (N = 202; 78% white; 71% men) were enrolled in the Buffalo Cardio-metabolic Occupational Police Stress study (2011–2014). Wrist actigraphy was used to assess sleep measures including sleep duration, sleep efficiency, sleep onset latency, wake after sleep onset, number of awakenings, and longest wake episode. CRAE and CRVE were obtained from fundus photography of retina and were averaged from both eyes per officer. We observed significant associations between sleep efficiency and CRVE (β = -2.81 µm; P= .046), and between longest wake episode and CRVE (β = 3.24 µm; P= .021). Adjustments for demographics, lifestyles, and physical and psychological factors attenuated these associations. Sex modified the independent associations of sleep onset latency and longest wake episode with CRVE. One standard deviation (SD) increase in sleep onset latency was associated with 4.81 µm larger CRVE (P= .028) (P-interaction = 0.098), and one SD increase in longest wake episode was associated with 4.62 µm larger CRVE (P= .032) (P-interaction = 0.115) among men. Race/ethnicity also modified the association between longest wake episode and CRVE (P-interaction = 0.088). A significant association was observed only among white officers (β = 4.96 µm; P= .025). We found that poor sleep quality, measured by longest wake episode, was positively and independently associated with retinal venular diameter among white and male officers. Longitudinal studies are warranted to assess whether poor sleep quality is a risk factor for retinal diameter changes.

description: Asthma is a heterogeneous disease with a range of observable phenotypes. To date, the characterization of asthma phenotypes is mostly limited to allergic versus non-allergic disease. Therefore, the aim of this big data study was to computationally derive asthma subtypes from the OneFlorida Clinical Research Consortium We obtained data from 2012-2020 from the OneFlorida Clinical Research Consortium. Longitudinal data for patients greater than two years of age who met inclusion criteria for an asthma exacerbation based on International Classification of Diseases codes. We used matrix factorization to extract information and K-means clustering to derive subtypes. The distributions of demographics, comorbidities, and medications were compared using Chi-square statistics. A total of 39,807 pediatric patients and 23,883 adult patients met inclusion criteria. We identified five distinct pediatric subtypes and four distinct adult subtypes. Pediatric subtype P1 had the highest proportion of black patients, but the lowest use of inhaled corticosteroids and allergy medications. Subtype P2 had a predominance of patients with gastroesophageal reflux disease, whereas P3 had a predominance of patients with allergic disorders. Adult subtype A2 was the most severe and all patients were on biologic agents. Most of subtype A3 patients were not taking controller medications, whereas most patients (>90%) in subtypes A2 and A4 were taking corticosteroids and allergy medications. We found five distinct pediatric asthma subtypes and four distinct adult asthma subtypes. Future work should externally validate these subtypes and characterize response to treatment by subtype to better guide clinical treatment of asthma.

description: To determine how kidney function identified by diagnosis codes compares to lab results-based kidney function for predicting the risk of vision-threatening diabetic retinopathy (VTDR). A US medical claims database was used for this retrospective observational study. Adult patients enrolled from January 1, 2002 to December 31, 2016 with nonproliferative diabetic retinopathy (NPDR) were followed. Patients were excluded if they had any previous diagnosis or treatment of VTDR or VTDR diagnosed within 2 years of insurance plan entry. ICD9/10 Chronic kidney disease (CKD) diagnoses from outpatient claims were used to classify kidney disease with or without end-stage renal disease (ESRD). Serum creatinine was used to calculate estimated glomerular filtration rates (eGFR). Multivariate Cox models with time-dependent covariates were used to assess the associations of kidney disease diagnosis and eGFR with progression to VTDR, controlling for demographics and time-dependent covariates (systemic health, laboratory results, insulin use). C-statistic (a measure of model discrimination), hazard ratio (HR) and their 95% confidence intervals (CI) were calculated from multivariate Cox models. Among 69,982 patients with NPDR, 12,770 (18.2%) developed VTDR. C-statistic was identical (0.60, 95% CI: 0.59–0.60) for the multivariate model with eGFR and for the multivariate model with kidney diagnosis codes. eGFRs lower than 30 mL/min/1.73 m2(HR>1.14, p p = .02) were associated with higher risk of progression to VTDR. Both diagnosis-based and lab results-based kidney function were associated with the development of VTDR and predict the development of VTDR equally well.

This molecule should be built by combining two atoms, for instance a protonium $(p\bar{p})$ and its heavier analogue $(d\bar{d})$. Most other four-body molecules have at least one stable three-body subsystem and thus can be built by adding the constituents one by one.

description: Purpose: Discriminating objects’ topological property (TP) is a primitive function of visual representation, which is reported to be associated with magnocellular (M) visual pathway, temporal lobe (TL), and superior colliculus (SC)-pulvinar subcortical pathway. Previous studies have shown that M pathway and TL were affected in high myopia (HM) subjects. The study was accordingly designed to explore whether topological perception performance was abnormal in HM subjects. Methods: 30 mildly myopic, 25 moderately myopic, 35 highly myopic, and 20 emmetropic subjects were enrolled. All participants underwent a comprehensive ophthalmological assessment including automated refraction, intraocular pressure, Humphrey 10–2 standard automated perimetry, ocular fundus photography and swept-source optical coherence tomography. Defined by differences in hole, TP and non-TP discrimination with letters “E”, “S”, “P”, “d” as stimuli in the central and peripheral regions was performed using the MATLAB 2017 software. d-primes extracted from the software were analyzed within each group. The correlation of peripheral TP/non-TP deficit with spherical equivalent (SE), axial length (AL) and average peripapillary retinal nerve fiber layer (RNFL) thickness was performed. Results: The patterns of topological perception performance were similar among the groups. TP discrimination peripherally was significantly better than that centrally in the mild myopia (P < .001), moderate myopia (P < .001), high myopia (P < .001) and emmetropia groups (P = .001). In the peripheral region, TP d-prime scores were significantly better than non-TP d-prime scores (all P < .001). The main and interaction effects of eccentricity and stimulus type were statistically significant(P < .05). There was no statistically significant correlation between peripheral TP/non-TP deficit and SE, AL or average RNFL thickness (P > .05). Conclusions: The current study first showed that patterns of topological perception among the myopic population were similar and not affected by the severity of myopia.

description: We study the insulator-superfluid transition of spin-1 bosons in an optical lattice in a uniform magnetic field. Based on a mean-field approximation we obtained a zero-temperature phase diagram. We found that depending on the particle number the transition for bosons with antiferromagnetic interaction may occur into different superfluid phases with spins aligned along or opposite to the field direction. This is qualitatively different from the field-free transition for which the mean-field theory predicts a unique (polar) superfluid state for any particle number.

description: In ergodic quantum systems, physical observables have a non-relaxing component if they "overlap" with a conserved quantity. In interacting microscopic models, how to isolate the non-relaxing component is unclear. We compute exact dynamical correlators governed by a Hamiltonian composed of two large interacting random matrices, $H=A+B$. We analytically obtain the late-time value of $\langle A(t) A(0) \rangle$; this quantifies the non-relaxing part of the observable $A$. The relaxation to this value is governed by a power-law determined by the spectrum of the Hamiltonian $H$, independent of the observable $A$. For Gaussian matrices, we further compute out-of-time-ordered-correlators (OTOCs) and find that the existence of a non-relaxing part of $A$ leads to modifications of the late time values and exponents. Our results follow from exact resummation of a diagrammatic expansion and hyperoperator techniques.

description: O presente trabalho tem como objetivo determinar as fontes de crescimento das lavouras temporárias no Estado da Bahia. Pois, com grandes alterações ocorrendo no meio rural ocorrida principalmente a partir de 1990 com o incremento tecnológico, abertura comercial, perda de capacidade de financiamento da agricultura pelo estado e a carência quase que total de informações no tocante ao cultivo das lavouras temporárias, é de grande valia estudos que demonstrem essas alterações de forma sistematizada. Com esse intuito, utilizou-se a metodologia “shift-share”, conhecida como diferencial – estrutural, na mensuração das fontes de crescimento das atividades agrícolas, tendo como fatores explicativos da evolução da produção os efeitos área, rendimento e localização geográfica. As alterações na área cultivada das culturas foram desmembradas em efeitos escala e substituição. Apesar da importância da pecuária na Bahia, as pastagens não foram incluídas no estudo devido à ausência de dados estatísticos. Verifica-se um grande crescimento da soja nos períodos em estudo. O efeito rendimento não se mostrou marcante no crescimento da produção das culturas, apontando um possível baixo nível tecnológico para algumas culturas. O fator área foi mais percebido no crescimento da produção das culturas, indicando um uso extensivo do solo. Percebe-se que a soja foi a cultura que obteve maiores ganhos em área no estudo, em detrimento da redução da área de outras culturas. O algodão, a cana, o feijão, o milho e a soja obtiveram crescimento da produção de 1985 a 2002, mas a mamona e a mandioca tiveram decréscimo da produção.

description: Improving lighting arrangements at the highway intersections can significantly reduce the likelihood of crashes. Meanwhile, a reasonable gradient illumination scheme can increase drivers' safety by avoiding the rapid change of their pupil area when driving from an unlighted area into a lighted area. The purpose of this study is to design illumination transition zones for drivers when approaching the highway intersection, and optimize the illumination increments along the transition zones. This issue is addressed in three stages. First, an indoor simulation platform is built using the UC-win/road software, and its parameters are calibrated using real intersection data collected at night. Second, the variation of pupil area under different increasing rates of illuminance near the driver's eyes (INDE) is analyzed, and a model representing the temporal change of the area in the pupil contraction stage is established. Last, an optimization model is proposed to obtain the optimal luminance increasing rates by minimizing the time needed for drivers to travel through the transition zones under different maximum illuminations and speed limits. The findings of this study indicate that the INDE increasing time in the transition zone remains unchanged with a determined illumination at the intersection, and the optimal transition zone length is directly proportional to the speed limit of the intersection. Therefore, the transition zone length needs to be adjusted to accommodate different speed limits: it should be extended or shortened by the same percentage as the increase or decrease of the speed limit. It can be concluded that the illumination transition zone is necessary when the INDE of highway intersection and the speed limit exceed 8 lx and 40 km/h, respectively. The INDE increasing rate should be maintained around the optimal value, providing safe and comfortable light adaptation to drivers and preventing traffic accidents. The study will provide a scientific basis for safety implementation of lighting arrangements at highway intersections.
Models of engagement for PhDs with non-academic partners
Creators: name: CESAER
Publisher: name: Zenodo
Year: 2024

description: This report explores the evolving models of engagement between PhD candidates at universities of science and technology (S&T) and non-academic partners, such as industry and societal institutions. These partnerships aim to foster societal engagement, enhance innovation efforts, and promote disruptive innovation within Europe.

The initiative was set in motion following an interest of our association to explore collaborations beyond academia, with a particular focus on boosting disruptive innovation. CESAER’s Task Force Innovation spearheaded this exploration, outlining a roadmap, conducting focus groups, and interviewing key stakeholders, including universities and industrial partners. The primary objective was to assess the role of industrial doctorates as drivers of innovation within European industry and as a mechanism for bridging academic research with practical applications inside and outside academia.

The report is grounded in findings from an online workshop organised by the Task Force Innovation in October 2023. Presentations from representatives of universities across Europe, including Universitat Politècnica de Catalunya (UPC), Ghent University, the University of Strathclyde, and the University of Stuttgart, provided insights into their models for integrating PhD research with industrial needs. The presentations highlighted the challenges and opportunities for PhD candidates, universities, and industrial partners, with an emphasis on how industrial doctorates can foster innovation and serve the needs of all stakeholders.

Throughout the workshop, various strategies were shared for overcoming challenges related to intellectual property rights, publication timelines, and aligning academic and industrial expectations. Additionally, the workshop facilitated discussions on the broader implications of these partnerships for enhancing innovation ecosystems across Europe.

This report includes key recommendations to universities, industry leaders, political decision-makers, and European Union institutions on how to further develop and support industrial doctorate programs. These recommendations stress the importance of fostering collaboration, developing clear intellectual property guidelines, and creating pathways to better align the career prospects of PhD candidates with industry needs. By leveraging the collective insights from these partnerships, the report suggests that industrial doctorates can significantly contribute to Europe’s leadership in innovation.

description: We have experimentally demonstrated a simplified method for performing single-shot supercontinuum spectral interferometry (SSSI) that does not require pre-characterization of the probe pulse. The method, originally proposed by D. T. Vu, D. Jang, and K. Y. Kim, uses a genetic algorithm (GA) and as few as two time-delayed pump-probe shots to retrieve the pump-induced phase shift on the probe [Opt. Express 26, 20572 (2018)]. We show that the GA is able to successfully retrieve the transient modulations on the probe, and that the error in the retrieved modulation decreases dramatically with the number of shots used. In addition, we propose and demonstrate a practical method that allows SSSI to be done with a single pump-probe shot (again, without the need for pre-characterization of the probe). This simplified method can prove to be immensely useful when performing SSSI with a low-repetition-rate laser source.

description: Photo-physical and nonlinear-optical properties of a new amphiphilic conjugated polymer: hydroxylated pyridyl para-phenylene (Py-PhPPP) both in CH2Cl2 solution and in thin films have been investigated. By using Z-scan technique with nanosecond laser pulses of wavelengths ranging from 430 to 600 nm, the large nonlinear absorption and refraction have been determined in terms of the effective third-order, nonlinear-optical susceptibilities. These Z-scans reveal that the nonlinear absorption alters from reverse saturable absorption to saturable absorption at wavelength of ~ 540 nm. Similarly, alteration from self-defocusing to self-focusing manifests itself at the same wavelength. The optical limiting performance of Py-PhPPP in solution is superior to toluene solution of [60]fullerene (C60) at 532 nm. Both UV-visible absorption spectra and photoluminescence (PL) spectra show concentration dependence. The PL spectra also depend on excitation wavelengths. These evidences suggest that the aggregate formation should play an important role in the nonlinear-optical properties of the new polymer. We attribute the reverse saturable absorption in the region of blue and green wavelengths mainly to intra-chain, triplet-triplet absorption while the absorption bleaching at longer wavelengths is due to saturation in the absorption band induced by the aggregates.

description: To determine the symmetry of retinopathy of prematurity (ROP) between fellow eyes in a broad-risk cohort. A retrospective cohort study, the Postnatal Growth and ROP (G-ROP) Study, of 7483 infants undergoing ROP examinations conducted at 29 hospitals in the United States and Canada from 2006 to 2012. The main outcomes were the symmetry for the highest stage and the most severe type (1, 2, not 1 or 2, no ROP) of ROP and disease course of the fellow eye when only one eye developed type 1. 93% of infants had eyes symmetric for the highest stage and 94% for type. Among 459 infants who developed type 1, 379 (82.6%) did so in both eyes simultaneously and were treated bilaterally; 44 (10%) were treated for type 1 in one eye and type 2 in the fellow eye; and 36 (8%) were treated unilaterally initially, of which 6 fellow eyes developed type 1 and were treated (4 within 2 weeks, all within 4 weeks); 5 developed type 2 and regressed; and 25 developed ROP less than type 1 or 2, which was treated in 13 cases and regressed spontaneously in 12 cases. ROP was highly symmetric between eyes with respect to the presence and severity of disease in a large, broad-risk cohort representative of infants undergoing ROP screening. When type 1 develops in one eye and type 2 in the fellow eye, the risk of progression to type 1 in the fellow eye appears very low if it has not occurred within 4 weeks.

Data Management

description: The multidisciplinary research unit 'Biodiversity and Sustainable Management of a Megadiverse Mountain Ecosystem in South Ecuador' established a central data management system to provide the members with all gathered scientific data. Additionally, to the database functionality of the system the web based layout is capable to present general information on the research unit to the public and support accounting and administration of the project. All parts of the system are implemented using open-source or free software. A major task is the allocation of a sophisticated and detailed metadata scheme. The standardized ecological metadata language (EML) is used as the basis for metadata information stored in a relational database. The describing datatypes are highly modular and can be expanded if necessary. Data input and searching is implemented through a dynamic webinterface with easy to use forms. This is important to increase the acceptance of the system by users. Searching the database is possible by strings for keywords, authors, etc. or by geographic locations. Except for gridded data, all single values of the datasets are stored in relational tables and thus, it is possible to extract only parts of a whole dataset during data download. While the system is already operational, modifications and new features are continuously implemented.

description: В данной статье исследуются структура, ключевые компоненты и принципы работы Segment Routing (SR). Сегментная маршрутизация представляет собой метод управления трафиком в глобальных сетях (WAN), который может быть реализован в сетях MPLS и сетях, использующих только BGP. SR рассматривается как инструмент для повышения производительности и оптимизации инфраструктуры. Основные преимущества SR достигаются благодаря интеграции с концепцией программно-определяемых сетей (SDN), при этом не требуется изменять стандартную плоскость передачи данных для технологий, на которых применяется SR. В статье также обсуждаются основные сферы применения SR, а также особенности его работы в централизованных и децентрализованных сетях.

description: A collaborative network is a social network that is comprised of experts who cooperate with each other to fulfill a special goal. Analyzing this network yields meaningful information about the expertise of these experts and their subject areas. To perform the analysis, graph embedding techniques have emerged as an effective and promising tool. Graph embedding attempts to represent graph nodes as low-dimensional vectors. In this paper, we propose a graph embedding method, called ExEm, that uses dominating-set theory and deep learning approaches to capture node representations. ExEm finds dominating nodes of the collaborative network and constructs intelligent random walks that comprise of at least two dominating nodes. One dominating node should appear at the beginning of each path sampled to characterize the local neighborhoods. Moreover, the second dominating node reflects the global structure information. To learn the node embeddings, ExEm exploits three embedding methods including Word2vec, fastText and the concatenation of these two. The final result is the low-dimensional vectors of experts, called expert embeddings. The extracted expert embeddings can be applied to many applications. In order to extend these embeddings into the expert recommendation system, we introduce a novel strategy that uses expert vectors to calculate experts' scores and recommend experts. At the end, we conduct extensive experiments to validate the effectiveness of ExEm through assessing its performance over the multi-label classification, link prediction, and recommendation tasks on common datasets and our collected data formed by crawling the vast author Scopus profiles. The experiments show that ExEm outperforms the baselines especially in dense networks.

Feedback in AGN heating of galaxy clusters

description: One of the challenges that models of AGN heating of the intracluster medium (ICM) face, is the question how the mechanical luminosity of the AGN is tuned to the radiative losses of the ICM. Here we implement a simple 1D model of a feedback mechanism that links the luminosity of the AGN to the accretion rate. We demonstrate how this simple feedback mechanism leads to a quasi-steady state for a broad range of parameters. Moreover, within this feedback model, we investigate the effect of thermal conduction and find that its relative importance depends strongly on the cluster mass.

description: Increasingly complex and autonomous systems require machine ethics to maximize the benefits and minimize the risks to society arising from the new technology. It is challenging to decide which type of ethical theory to employ and how to implement it effectively. This survey provides a threefold contribution. First, it introduces a trimorphic taxonomy to analyze machine ethics implementations with respect to their object (ethical theories), as well as their nontechnical and technical aspects. Second, an exhaustive selection and description of relevant works is presented. Third, applying the new taxonomy to the selected works, dominant research patterns, and lessons for the field are identified, and future directions for research are suggested.

description: Pelvic target dose from intensity-modulated proton therapy (IMPT) is sensitive to patient bowel motion. Robustly optimized plans in regard to bowel filling may improve the dose coverage in the treatment course. Our purpose is to investigate the effect of air volume in large and small bowel and rectum on target dose from IMPT plans. Data from 17 cancer patients (11 prostate, 3 gynecologic, 2 colon, and 1 embryonal rhabdomyosarcoma) with planning CT (pCT) and weekly or biweekly scanned quality assurance CTs (QACTs; 82 QACT scans total) were studied. Air in bowels and rectum traversed by proton pencil beams was contoured. The robust treatment plan was made by using 3 CT sets: the pCT set and 2 virtual CT sets that were copies of pCT but in which the fillings of bowels and rectum were overridden to be either air or muscle. Each plan had 2–5 beams with a mean of 3 beams. Targets in the pCT were mapped to the QACTs by deformable image registration, and the dose in QACTs was calculated. Dose coverage (D99 and D95) and correlations between dose coverage and changes in air volume were analyzed. The significance of the correlation was analyzed by t test. Mean changes of D99 in QACTs were within 3% of those in the pCT for all prostate and colon cases but >3% in 2 of the 3 gynecologic cases and in the embryonal rhabdomyosarcoma case. Of these three cases with mean change of D99 > 3%, air volume may be the main cause in 2. For the prostate cases, correlation coefficients were <0.7 between change in air volume and change in D99 and D95, because other anatomy changes also contributed to dose deviation. Correlation coefficients in the non-prostate cases were >0.9 between D99 change and rectum and between D95 change and small bowel, indicating a greater effect of the air volume on target dose. The air volume may still have an important effect on target dose coverage in treatment plans using 3 CT sets, particularly when the air is traversed by multiple beams.
Confined Coulomb systems with absorbing boundaries: the two-dimensional two-component plasma

description: Using a solvable model, the two-dimensional two-component plasma, we study a Coulomb gas confined in a disk and in an annulus with boundaries that can adsorb some of the negative particles of the system. We obtain explicit analytic expressions for the grand potential, the pressure and the density profiles of the system. By studying the behavior of the disjoining pressure we find that without the adsorbing boundaries the system is naturally unstable, while with attractive boundaries the system is stable because of a positive contribution from the surface tension to the disjoining pressure. The results for the density profiles show the formation of a positive layer near the boundary that screens the adsorbed negative particles, a typical behavior in charged systems. We also compute the adsorbed charge on the boundary and show that it satisfies a certain number of relations, in particular an electro-neutrality sum rule.
