description: En la República Dominicana, los principales problemas de la producción de plántulas forestales a raíz dirigida, están relacionados con la calidad del sustrato empleado, teniéndose, a menudo, que importar peat moss para prcxlucir un buen sustrato. El objetivo de este estudio fue encontrar un sustrato elaborado con materias primas nacionales que pueda sustituir el peal moss. El mismo fue realizado en el Instituto Superior de Agricultura, La Herradura, Santiago. El diseño empleado fue de parcelas divididas, con 25 combinaciones factoriales [(8 proporciones de mezclas x 3 materias primas) + 1 testigo] en las parcelas grandes y cinco especies forestales (Pinus caribaea, Leucaena leucocephala, Ca/talpa /ongissima, Auldirachta indica y Acacia mangium) en las subparcelas. Las proporciones de mezclas fueron 10,20,30,40,60, 70,80 y 90 por ciento de suelo turboso; el cual estuvo presente en todas las combinaciones. El porcentaje restante correspondió a una de las tres materias primas (cáscara de arroz, fibras de coco y cachaza de caña). El testigo fue 75% peal moss y 25% suelo turboso. Se midió el incremento en altura y la producción de materia seca de las especies y se observó la consistencia del terrón formado por el sustrato. Se encontró diferencias significativas entre los sustratos para el incremento en alturas, pero no en la producción de materia st!ca. La interacción sustratos-especies no fue significativa en ninguna de las dos variables. Los sustratos 30% cáscara de arroz + 70% turba, 60% cáscara de arroz + 40% turba, 70% cáscara de arroz + 30% turba, 90% cáscara de arroz y 30% fibras de coco + 70% turba tuvieron comportamiento similar al testigo (mejor), no existiendo diferencias significativas entre ellos.

description: Cnidoscolus quercifolius is an Euphorbiaceae endemic to the northeast region of Brazil, which is used in folk medicine as anti-inflammatory, analgesic and antibiotic. An ethanolic extract was prepared with the leaves from C. quercifolius, and also partitioned and chromatographed leading to the isolation of cyanoglucoside linamarin (1), cinnamic acid (2), as well as a mixture of steroids and terpenoids (3–6). Structural elucidation of the compounds was done by IR, MS and NMR analysis. For the cyanoglucoside (1) were also evaluated its antimicrobial and antileishmanial viabilities by plaque microdilution and MTT test, respectively. Both tests showed from moderate to zero activity against the organisms evaluated. In addition, the antiproliferative activity of compounds 1 and 5–6 were tested against tumor cells, which did not show statistically significant growth inhibition 50% (GI50). The obtained results suggested that further pharmacological studies should prove the folk medicinal uses.

description: We use an entanglement measure that respects the superselection of particle number to study the non-local properties of symmetry-protected topological edge states. Considering half-filled M-leg Su-Schrieffer-Heeger (SSH) ladders as an example, we show that the topological properties and the operational entanglement extractable from the boundaries are intimately connected. Topological phases with at least two filled edge states have the potential to realize genuine, non-bipartite, many-body entanglement which can be transferred to a quantum register. The entanglement is extractable when the filled edge states are sufficiently localized on the lattice sites controlled by the users. We show, furthermore, that the onset of entanglement between the edges can be inferred from local particle number spectroscopy alone and present an experimental protocol to study the breaking of Bell's inequality.

description: JohnnyVon is an implementation of self-replicating machines in continuous two-dimensional space. Two types of particles drift about in a virtual liquid. The particles are automata with discrete internal states but continuous external relationships. Their internal states are governed by finite state machines but their external relationships are governed by a simulated physics that includes Brownian motion, viscosity, and spring-like attractive and repulsive forces. The particles can be assembled into patterns that can encode arbitrary strings of bits. We demonstrate that, if an arbitrary "seed" pattern is put in a "soup" of separate individual particles, the pattern will replicate by assembling the individual particles into copies of itself. We also show that, given sufficient time, a soup of separate individual particles will eventually spontaneously form self-replicating patterns. We discuss the implications of JohnnyVon for research in nanotechnology, theoretical biology, and artificial life.

New approaches to the optimized maintenance of embryonic stem cells in culture
Creators: name: Glover, Clive Hamilton
Publisher: name: University of British Columbia
Year: 2011

description: The realization of many stem cell-based therapies will rely on the development of methods for the expansion and controlled differentiation of stem cells and the development of assays to rapidly detect the results of culture manipulation. Mouse embryonic stem cells (ESC) provide a relatively abundant and high purity model system to investigate environmental cues that influence stem cell fate. The dynamics of loss of pluripotency following the removal of leukemia inhibitory factor (LIF) were investigated using three functional assays (chimeric mouse formation, embryoid body generation and colony forming ability). A rapid loss (>70%) of pluripotent cells was detected within 24 hours, with very low residual activity by all criteria within 72 hours. Surprisingly, functional endpoints of pluripotency correlated poorly with two commonly used markers, expression of Oct4 and SSEA-1. The embryoid body assay was then used in factorial and central composite design experiments to define optimized levels of ascorbic acid (AA), chondroitin sulphate and PD98059 (PD), three factors that enhance undifferentiated ESC maintenance. These experiments identified an unexpected negative interaction between AA and PD and allowed the development of a cocktail of these three factors that increased ESC yield 3-fold over untreated cultures. To identify more rapid endpoints for the detection of undifferentiated ESC, global gene expression profiling was performed on ESC induced to differentiate by removal of LIF, addition of retinoic acid and addition of DMSO. Gene expression profiles were determined using the Affymetrix platform and a new meta-analysis methodology was developed and applied to the resulting gene expression data sets. This analysis revealed that the expression of the stem cell factor receptor, c-kit, expressed on the cell surface, correlated with the frequency of undifferentiated ESC making it an ideal marker for further studies. Furthermore, the expression changes of seven genes - 103728_at, 8430410A17Rik, klf2, nr0b1, sox2, tcll and zfp42 - was able to predict undifferentiated ESC frequencies in both differentiation and maintenance cultures. These experiments should provide a useful framework for making further improvements in the culture of undifferentiated ESC.

description: The SAFERS project aims to develop a comprehensive, emergency management system for the management of forest fires. The project is funded by the European Union's Horizon 2020 research and innovation programme under Grant Agreement No. 869353.
description: Changing climate is increasing the risk of wildfires. As temperatures continue to soar in the future, scientists warn that extreme fires will become more common. Meaningful early warning forecasts, early identification and tracking as well as effective response are of paramount importance to save lives and contain environmental damage. The EU-funded SAFERS project will develop a complex emergency management system capable of acting along the whole emergency management cycle, thanks to the coupled use of heterogeneous Big Data, advanced models, and AI. Earth Observation data from Copernicus and GEOSS will be the primary data source, which will be combined with data from social media, smoke detectors, and mobile applications. This will allow first responders, citizens and decision makers to generate new and more accurate information, enhancing our society's resilience against wildfires.
description: Land cover (LC) segmentation plays a critical role in various applications, including environmental analysis and natural disaster management. However, generating accurate LC maps is a complex and time-consuming task that requires the expertise of multiple annotators and regular updates to account for environmental changes. In this work, we introduce SPADA, a framework for fuel map delineation that addresses the challenges associated with LC segmentation using sparse annotations and domain adaptation techniques for semantic segmentation. Performance evaluations using reliable ground truths, such as LUCAS and Urban Atlas, demonstrate the technique's effectiveness. SPADA outperforms state-of-the-art semantic segmentation approaches as well as third-party products, achieving a mean Intersection over Union (IoU) score of 42.86 and an F1 score of 67.93 on Urban Atlas and LUCAS, respectively.

description: Come2Data is one of eleven national Data Competence Centres currently in development. It aims to foster the proliferation of data competencies and skills primarily in academia, but also in public administration, industry and the interested public. It follows an interdisciplinary, regional approach by bringing together existing data-related teaching, training and support services of the project partners (TU Chemnitz, TU Dresden, Leipzig University and Saxon State Library – Dresden State and University Library) as well as expertise and activities on research data management (e.g. in SaxFDM), the National Research Infrastructure (NFDI) and high-performance computing and analysis methods for data-intensive, interdisciplinary research applications, such as artificial intelligence and data modelling (e.g. in ScADS.AI).

Information on offerings and resources will be aggregated and made accessible via a virtual platform serving as a central entry point. Existing teaching offers and materials will be didactically overhauled, tailored to different target groups and arranged in learning paths on a modular basis. Findings and solutions developed as part of pilot projects from various disciplines will be integrated. In addition, Come2Data will explore possibilities for the integration of data-related content into curricula and teaching as well as certification and implement them on a trial basis.

description: Context: Security Vulnerabilities (SVs) pose many serious threats to software systems. Developers usually seek solutions to addressing these SVs on developer Question and Answer (Q&A) websites. However, there is still little known about on-going SV-specific discussions on different developer Q&A sites. Objective: We present a large-scale empirical study to understand developers' SV discussions and how these discussions are being supported by Q&A sites. Method: We first curate 71,329 SV posts from two large Q&A sites, namely Stack Overflow (SO) and Security StackExchange (SSE). We then use topic modeling to uncover the topics of SV-related discussions and analyze the popularity, difficulty, and level of expertise for each topic. We also perform a qualitative analysis to identify the types of solutions to SV-related questions. Results: We identify 13 main SV discussion topics on Q&A sites. Many topics do not follow the distributions and trends in expert-based security sources such as Common Weakness Enumeration (CWE) and Open Web Application Security Project (OWASP). We also discover that SV discussions attract more experts to answer than many other domains, but some difficult SV topics (e.g., Vulnerability Scanning Tools) still receive quite limited support from experts. Moreover, we identify seven key types of answers given to SV questions on Q&A sites, in which SO often provides code and instructions, while SSE usually gives experience-based advice and explanations. Conclusion: Our findings provide support for researchers and practitioners to effectively acquire, share and leverage SV knowledge on Q&A sites.

description: The impacts of climate change on the agricultural sector in Nigeria going forward are expected to be severe, but so far there is a dearth of systemic analysis of how these impacts would develop over time, or how they would interact with other drivers impacting Nigerian agriculture. Such a systemic analysis could contribute to adaptation efforts by identifying policy mechanisms that serve as system ‘levers’ to effect change given the considerable uncertainty associated with both the socio-economic and ecological aspects of climate change. This study begins to provide a systematic analysis of the impact of climate change on agricultural production in Nigeria using a participatory research method. We convened a workshop of key stakeholders with diverse and in-depth knowledge of Nigerian agriculture in Ibadan, Nigeria, in June, 2016. Using a causal loop diagramming (CLD) technique, we grouped these stakeholders by region and led them through an exercise in which they drew diagrams depicting the barriers to, and opportunities for, Nigerian agricultural development.

description: - NPIC&HMIT 2021 Conference Paper
- Minimizing the chances of operator error in the nuclear plant control room is a prominent goal for the nuclear industry. Therefore, research efforts have been directed towards minimizing human error by increasing automation in the Nuclear Power Plant (NPP) using Machine Learning (ML) methods to develop ML-based Operator Support Systems (OSSs). These support systems integrate information across the control room to assist the operator in fault diagnosis and making faster efficient decisions. With the increased reliance on machine learning in nuclear plant management, there is a need to reason about the trustability of these ML-based operator systems.
- In this work, we propose an automated reasoning-based system that checks for discrepancies and decides whether the predictions and actions recommended by ML-based OSSs can be trusted. To demonstrate this reasoning-based discrepancy checker's capability, we apply it to an implementation of the Nearly Autonomous Management and Control (NAMAC) system that was presented in [1]. The discrepancy checker takes into consideration some trustability metrics such as 1- The similarity between the ML training scenario and the actual scenario, 2- The discrepancy between the actual effect of the corrective action recommended by an ML model and the desired action effect, 3- The discrepancy between the ML-based predictions and the actual sensor readings.

description: An alley cropping experiment was conducted to determine the effects of pigeonpea [ Cajanus cajall (L.) Millsp.] hedgerows on soil water and yield of intercropped pepper ( Capsicum a11nuum L.). Results showed that soil water content in hedgerow intercropping was generally higher than the control (no hedgerows) which was attributed to the combined effects of low evapotranspiration, reduced wind speed and green manure mulch. In spite of high soil water content and low evapotranspiration, total water use in hedgerow intercropping was slightly higher than the control. Low pepper plant population due to intercropping and the combined effects of partial shading by hedgerows and competition for soil water resulted in significant (P< .01) yield reduction of intercropped peppers ranging from 48 to 58%. These results indicate that alley cropping pigeonpea with vegetable crops has some limitations even with irrigation in the semi-arid tropics. However, its positive effect on microclimate and soil may lead to long term benefits for vegetable crop production in the semi-arid tropics.

description: Low-mass and brown dwarfs have recently been found as wide companions to many nearby stars, formerly believed to be single. Wide binaries are usually found as common proper motion pairs. Sometimes, more than two objects share the same large proper motion, identifying them as nearby systems. We have found a third, low-mass component to a known wide binary at a distance of about 21pc, consisting of a red and a white dwarf (LHS4039 and LHS4040; about 150AU separation). The new companion, APMPMJ2354-3316C separated by about 2200AU, was classified as M8.5 dwarf. In recent spectroscopic observations it shows a very strong $H_α$ emission line and blue continuum. Comparing this event to flares in late-type M dwarfs, we find some similarity with LHS2397a, a nearby M8 dwarf which is so far the only known example of a low-mass star with a tight brown dwarf companion (separation of less than 4AU). The level of the activity as measured by $L_{H_α}/L_{bol}$ is comparable to that of the M9.5 dwarf 2MASSWJ0149+29 both during the flare and in quiescence.

description: Several sweet potato (lpomoea batatas (L.) Lam) cultivars were field planted in a series of gennplasm evaluation trials in the U.S. Virgin Islands. The objective of these trials was to identify and select suitable cultivars for local production based upon yield, sweet potato weevil (SPW) tolerance, growth-vigor and culinary qualities. Cultivars evaluated were obtained from the USDA-Tropical Agriculture Research Station (TARS) in Mayaguez, Puerto Rico; St. Kitts; South Florida and local farmers in St. Croh. There was a tendency for high-yielding cultivars to have a higher percentage_ of storage roots infested by SPW. In Experiment 1, Miguela and Toquesita produced the highest total -yields, while Toquesita had the highest marketable yield. Seventy nine percent of the storage roots produced by Miguela were damaged by SPW. Colorette, Perla, Agata and Amarista produced the highest total yield in Experiment 2. Colorette also produced the highest (P<0.05) quantity of marketable storage roots. Agata and Amarista suffered high levels of SPW damage. In Experiment 3, Twelve Prime produced the highest total (P<0.05), and marketable yields. Trompo Negro also produced a relatively good marketable yield. Of the cultivars evaluated in Experiment 4, Violjl, Tapato and SUMy were the best yielding in terms of total storage roots (19.5, 16.4 and 14.3 ton/ha, respectively) and mar)cetable storage roots (16.2, 14.2 and 13.1 ton/ha, respectively). Pi(ladito produced the largest (P < 0.05) storage roots, weighing an average of 438 g. In Experiment 5, Perla, Viola, Tapato and SUMy had the highest yields of sweet potato 'Storage roots, while SKB-4,· CS-2 and SKB-2 had the highest foliage yield. Tapato produced the largest sweet potatoes (438

description: We show that the entropy of cosmological perturbations originating as quantum vacuum fluctuations in the very early universe, including the contribution of the leading nonlinear interactions, can be viewed as momentum space entanglement entropy between sub- and super-Hubble modes. The interactions between these modes causes decoherence of the super-Hubble fluctuations which, in turn, leads to a non-vanishing entropy of the reduced density matrix corresponding to the super-Hubble inhomogeneities. In particular, applying this to inflationary cosmology reveals that the entanglement entropy produced by leading order nonlinearities dominates over that coming from the squeezing of the vacuum state unless inflation lasts for a very short period. Furthermore, demanding that this entanglement entropy be smaller than the thermal entropy at the beginning of the radiation phase of standard cosmology leads to an upper bound on the duration of inflation which is similar to what is obtained from the Trans-Planckian Censorship Conjecture.

description: We have designed and prototyped the process steps for the batch production of large-area micro-channel-plate photomultipliers (MCP-PMT) using the "air-transfer" assembly process developed with single $LAPPD^{\text{TM}}$ modules. Results are presented addressing the challenges of designing a robust package that can transmit large numbers of electrical signals for pad or strip readout from inside the vacuum tube and hermetically sealing the large-perimeter window-body interface. We have also synthesized a photocathode in a large-area low-aspect-ratio volume, and shown that the micro-channel plates recover their functionality after cathode synthesis. The steps inform a design for a multi-module batch facility employing dual nested low-vacuum (LV) and ultra-high-vacuum (UHV) systems in a small-footprint. The facility design provides full access to multiple MCP-PMT modules prior to hermetic pinch-off for leak-checking and real-time photocathode optimization.

description: Using detailed mock galaxy redshift surveys we investigate to what extent the kinematics of large samples of satellites galaxies extracted from flux-limited surveys can be used to constrain halo masses. Previous host-satellite selection criteria yield relatively large fractions of interlopers and with a velocity distribution that, contrary to what has typically been assumed, differs strongly from uniform. A new adaptive selection criterion is proposed which yields much larger host-satellite samples and with strongly reduced interloper fractions. We show that satellite weighting, which occurs naturally when stacking many host-satellite pairs, introduces a bias towards higher velocity dispersions compared to the true, host-averaged mean. A further bias, in the same direction, is introduced when using flux-limited, rather than volume-limited surveys. We apply our adaptive selection criterion to the 2dFGRS and obtain a sample of 12613 satellite galaxies and 8004 host galaxies. The satellite kinematics are in excellent agreement with predictions based on the conditional luminosity function (CLF), providing independent, dynamical confirmation of the average mass-to-light ratios predicted by the CLF formalism.

description: The formation and evolution of disk-dominated galaxies is difficult to explain, yet these objects exist. We therefore embarked on a study aimed at a better understanding of these enigmatic objects. We used data from the SDSS DR1 in order to identify edge-on galaxies with disks in a uniform, reproducible, automated fashion. We identified 3169 edge-on disk galaxies, which we subdivided into disk galaxies with bulge, intermediate types, and simple disk galaxies without any obvious bulge component. We subdivided these types further into subclasses: Sa(f), Sb(f), Sc(f), Scd(f), Sd(f), Irr(f), where the (f) indicates that these galaxies are seen edge-on. A number of incompleteness effects affect our catalog, but it contains almost a factor of four more bulgeless galaxies with prominent simple disks (flat galaxies) within the area covered here than previous optical catalogs, which were based on the visual selection from photographic plates. We find that approximately 15% of the edge-on disk galaxies in our catalog are flat galaxies, demonstrating that these galaxies are fairly common, especially among intermediate-mass star-forming galaxies. Bulgeless disks account for roughly one third of our galaxies when also puffy disks and edge-on irregulars are included.(Abridged)

description: Using data from multiple sources we explore the dynamic growth and transformation that is taking place in the Nigerian poultry subsector. We find that increased consumption of poultry products in Nigeria is occurring alongside rapid urbanization and growth in the poultry industry. In just one decade, the volume of feed used in Nigeria skyrocketed from 300 thousand to 1.8 million tons – a 600% climb. Contrary to the idea that Nigeria is inundated with illegal imports of poultry products, we find that domestic production covers about 85% of domestic consumption, and (illegal) imports appear to be only about 15% of consumption. This indicates that efforts towards addressing illegal smuggling of poultry products into Nigeria should be supplemented with at least equal effort to ensuring the sustainable growth of domestic poultry production in the country.

Baryogenesis from the Kobayashi-Maskawa Phase

description: The Standard Model fulfills the three Sakharov conditions for baryogenesis. The smallness of quark masses suppresses, however, the CP violation from the Kobayashi-Maskawa phase to a level that is many orders of magnitude below what is required to explain the observed baryon asymmetry. We point out that if, as a result of time variation in the Yukawa couplings, quark masses were large at the time of the electroweak phase transition, then the Kobayashi-Maskawa mechanism could be the source of the asymmetry. The Froggatt-Nielsen mechanism provides a plausible framework where the Yukawa couplings could all be of order one at that time, and settle to their present values before nucleosynthesis. The problems related to a strong first order electroweak phase transition may also be alleviated in this framework. Our scenario reveals a loophole in the commonly held view that the Kobayashi-Maskawa mechanism cannot be the dominant source of CP violation to play a role in baryogenesis.

The education of Rosalind Krauss, Peter Eisenman, and other Americans : why the fantasy of postmodernism still remains
Creators: name: Epp, Colin Brent

description: Within current art and architectural circles the term postmodernism has a dated air about it. It has long been shorn of its currency in any meaningful dialogue about the state of art and architectural production. Instead, the name recalls for most a notion that was fashionable in the 1970s and 1980s, suggesting a manifold of concepts like historical quotation, allegory, appropriation, pastiche, the culture of late capitalism, the end of grand narratives, the critique of the authorial subject, the collapse of the Enlightenment project, pluralism. Yet, for all this, it has not been properly historicized. This thesis proposes to historicize the production and circulation of the term postmodernism, paying attention to two of its most important sites: October, a journal of art criticism founded in 1976, and Oppositions, an architectural periodical that was first published in 1973. With this aim, I turn to the dialogue between Rosalind Krauss and Peter Eisenman that took place between 1969 and 1976, as each broke ties with certain aspects of her and his intellectual formation represented by Michael Fried and Colin Rowe. The rejection of the latter critics' anti-literalism propels the dialogue. But it was founded on a faultline--one that points to a difference much more significant than supposed between art and architecture, and one that could only be diffused by a discourse on institutions. The political critiques of the institutions of art and architecture that emerged alongside alternative spaces and that were enunciated in October and Oppositions are part of a broader discourse on institutions and have their mirror reflection on the right. Neoconservatives set up their own alternative spaces in corporate-funded think tanks and from there launched their attacks on the liberalism they saw as being entrenched in the institutions supported by government and the university. I argue that the fantasy of postmodernism served to make illegible deep contradictions, not between claims about institutions by left and right, but between the different significations called forth by the figure "institution,'' showing that fantasies of efficiency have a deeper set of effects and conditions than the political claims based on them.

description: Rural Malians who grow dryland crops depend on sorghum as a primary food staple. Achieving major gains in national sorghum yields in the complex and variable sorghum environments of Mali has been challenging despite steady advances in sorghum research. Since 2000, Mali’s sorghum research program has shifted from formal plant breeding with a state-managed seed system (FPB-S) toward a more participatory approach with on-farm tests and trials, and decentralized seed supply managed by local farmer associations (PPB-F). Recently, the program released the first Guinea-race sorghum hybrids developed in Mali, based largely on germplasm of local landraces. Of the five races of sorghum grown in Africa South of the Sahara, the Guinea race dominates the West African Savanna, where most of Africa’s sorghum is produced. Aside from photoperiod sensitivity, the defining traits of the Guinea race are the shape of the grain and the fact that the grains turn inside the glumes at maturity, leaving open glumes and lax panicles that help to mitigate grain damage from insects and mold.

description: We present the stellar kinematics of 48 representative elliptical and lenticular galaxies obtained with our custom-built integral-field spectrograph SAURON operating on the William Herschel Telescope. The data were homogeneously processed through a dedicated reduction and analysis pipeline. All resulting SAURON datacubes were spatially binned to a constant minimum signal-to-noise. We have measured the stellar kinematics with an optimized (penalized pixel-fitting) routine which fits the spectra in pixel space, via the use of optimal templates, and prevents the presence of emission lines to affect the measurements. We have thus generated maps of the mean stellar velocity, the velocity dispersion, and the Gauss-Hermite moments h3 and h4 of the line-of-sight velocity distributions. The maps extend to approximately one effective radius. Many objects display kinematic twists, kinematically decoupled components, central stellar disks, and other peculiarities, the nature of which will be discussed in future papers of this series.

description: The available virial coefficients for the 2D hard disks model are transformed into a matrix representation of the thermodynamic potentials, which allows for an accurate description of the whole fluid phase, up to the phase transition. We find that the fluid phase terminates at the transition point, supporting the Kosterlitz-Thouless-Halperin-Nelson-Young picture of a second order phase transition into a Hexatic phase. The density and pressure at the transition are calculated from the available first ten virial coefficients, and are found to be in excellent agreement with recent Monte-Carlo calculations. Finally, we calculate the equation of state in the critical region.
