Heavy quarkonium: progress, puzzles, and opportunities
A golden age for heavy quarkonium physics dawned a decade ago, initiated by
the confluence of exciting advances in quantum chromodynamics (QCD) and an
explosion of related experimental activity. The early years of this period were
chronicled in the Quarkonium Working Group (QWG) CERN Yellow Report (YR) in
2004, which presented a comprehensive review of the status of the field at that
time and provided specific recommendations for further progress. However, the
broad spectrum of subsequent breakthroughs, surprises, and continuing puzzles
could only be partially anticipated. Since the release of the YR, the BESII
program concluded only to give birth to BESIII; the -factories and CLEO-c
flourished; quarkonium production and polarization measurements at HERA and the
Tevatron matured; and heavy-ion collisions at RHIC have opened a window on the
deconfinement regime. All these experiments leave legacies of quality,
precision, and unsolved mysteries for quarkonium physics, and therefore beg for
continuing investigations. The plethora of newly-found quarkonium-like states
unleashed a flood of theoretical investigations into new forms of matter such
as quark-gluon hybrids, mesonic molecules, and tetraquarks. Measurements of the
spectroscopy, decays, production, and in-medium behavior of c\bar{c}, b\bar{b},
and b\bar{c} bound states have been shown to validate some theoretical
approaches to QCD and highlight lack of quantitative success for others. The
intriguing details of quarkonium suppression in heavy-ion collisions that have
emerged from RHIC have elevated the importance of separating hot- and
cold-nuclear-matter effects in quark-gluon plasma studies. This review
systematically addresses all these matters and concludes by prioritizing
directions for ongoing and future efforts.Comment: 182 pages, 112 figures. Editors: N. Brambilla, S. Eidelman, B. K.

Comportamento de cultivares de pepino (Cucumis sativus L.) em duas épocas de semeadura
Plant development and fruit production of cucumber cultivars 'Marketer IAC- 2 2 0 5 ' , 'Palomar IAC- 3 0 5 0 ' , 'Santee IAC- 2 4 4 1 ' , 'Verde Paulistano IAC-1336' and 'Aodai 1 - 4 3 2 1 ' were compared under two sowing dates, 5 t n of May and 5 t n of December of 1970 in Campinas, SP, Brazil, in a Yellow Red Latossol. Air temperature ranged from 1 2 , 0°C to 26, 8°C in the first period of culture, and from 18,5°C to 30,2°C in the second period. Adequate cultural practices were provided. When the first female flower appeared in the field, insecticides and fungicides applications were interrupted. For all cultivars, yields were higher and fruit quality was better in the first period of culture. Both in May and December cultures, plants have concentrated their highest yields between the third and the penultima te harvesting dates. 'Santee' presented low yields and the quality of its fruits was poor. 'Aodai' showed the best results as to fruit yield and fruit quality. Yields of the other cultivars were similar. 'Verde Paulistano' presented the latest fruit production. 'Marketer' showed a relatively uniform behaviour in both periods of culture. There were found positive correlations between yield in each harvesting date and total yield, total yield and marketable yield, number of fruits and fruits weight, plant height and yield, and number of lateral branches and yield. The relation between marketable and total yield, and fruit average weight, decreased at the end of the plants cycle.O desenvolvimento e a produção de frutos para consumo in natura dos cultivares de pepino 'Marketer IAC-2205', 'Palomar IAC-3050', 'Santee IAC-2441', 'Verde Paulistano IAC-1386' e 'Aodai 1-4321' foram estudados em duas épocas de semeadura, 5 de maio e 5 de dezembro, em Campinas, SP. Para todos os cultivares, as plantas semeadas em dezembro cresceram mais e desenvolveram-se com maior rapidez que as plantas semeadas em maio; entretanto, as produções das plantas semeadas em maio foram maiores e a qualidade de seus frutos foi superior. Tanto para as plantas semeadas em maio como para as semeadas em dezembro, 'Santee' apresentou produções baixas e frutos de má qualidade. 'Aodai' foi o cultivar mais produtivo e seus frutos foram os de melhor qualidade. As produções dos demais cultivares foram equivalentes. 'Verde Paulistano' apresentou a produção mais tardia. 0 comportamento de 'Marketer' foi pouco afetado pelas variações ambientais. As maiores produções de todos os cultivares, nas duas é poças, foram obtidas entre a terceira e a penúltima colheitas. Foram encontradas correlações positivas entre a produção de cada colheita e a produção total, entre a produção total e a produção comerciável, entre o número de frutos e seu peso, entre produção e a altura da planta e entre produção e número de ramos laterais da planta. A relação entre produções comerciável e total e o peso médio dos frutos diminuíram no final do ciclo das plantas

The Galaxy platform for accessible, reproducible, and collaborative data analyses: 2024 update
YesGalaxy (https://galaxyproject.org) is deployed globally, predominantly through free-to-use services, supporting user-driven research that broadens in scope each year. Users are attracted to public Galaxy services by platform stability, tool and reference dataset diversity, training, support and integration, which enables complex, reproducible, shareable data analysis. Applying the principles of user experience design (UXD), has driven improvements in accessibility, tool discoverability through Galaxy Labs/subdomains, and a redesigned Galaxy ToolShed. Galaxy tool capabilities are progressing in two strategic directions: integrating general purpose graphical processing units (GPGPU) access for cutting-edge methods, and licensed tool support. Engagement with global research consortia is being increased by developing more workflows in Galaxy and by resourcing the public Galaxy services to run them. The Galaxy Training Network (GTN) portfolio has grown in both size, and accessibility, through learning paths and direct integration with Galaxy tools that feature in training courses. Code development continues in line with the Galaxy Project roadmap, with improvements to job scheduling and the user interface. Environmental impact assessment is also helping engage users and developers, reminding them of their role in sustainability, by displaying estimated CO2 emissions generated by each Galaxy job.NIH [U41 HG006620, U24 HG010263, U24 CA231877, U01 CA253481]; US National Science Foundation [1661497, 1758800, 2216612]; computational resources are provided by the Advanced Cyberinfrastructure Coordination Ecosystem (ACCESS-CI), Texas Advanced Computing Center, and the JetStream2 scientific cloud.

Zoologia neocaledonica : 8. Biodiversity studies in New Caledonia
Lacertoides pardalis est un scinque endémique de grande taille, caractérisé par de petites écailles sur tout le corps. Cette espèce a été décrite pour la première fois en 1997, à partir de 2 spécimens en provenance d'un unique site de récolte, dans l'extrême sud de la Grande Terre. Depuis la description originale, il y a une dizaine d'année, plusieurs individus ont été capturés dans la même région (des juvéniles mais également des spécimens adultes de grande taille). Ces captures permettent de fournir des informations sur la biologie et l'écologie de l'espèce, en particulier, une reproduction vivipare et un régime alimentaire généraliste, reposant sur de la prédation d'invertébrés mais également sur d'autres espèces de reptiles et de façon plus inattendue avec une frugivorie importante. L. pardalis pourrait jouer un rôle important pour la dissémination de certaines espèces du maquis, voire de lisières forestières. Ces nouvelles captures ont permis d'élargir significativement l'aire de répartition connue de l'espèce, qui est considéré vulnérable (VU) selon les critères de la liste rouge de l'IUCN. Cependant, la région d'où est connue L. pardalis a subi de profondes transformation au cours de la dernière décennie, en raison du développement de projet minier sur le plateau de Goro. Des études complémentaires restent à mener pour conserver cette espèce originale et unique des habitats de maquis rocheux du sud de la Nouvelle-Calédonie
Zoologia neocaledonica : 8. Biodiversity studies in New Caledonia
Les scinques du genre Sigaloseps sont révisés à la lumière des informations obtenues à partir des collections réalisées ces dix dernières années. Les résultats du terrain, des études morphologiques et de la génétique mettent en évidence un complexe de trois taxons autrefois confondus sous le binôme Sigaloseps deplanchei, deux taxons identifiés comme Sigaloseps ruficauda et une autre espèce sans affinités morphologiques apparentes avec un autre taxon décrit. Toutes les espèces sont restreintes à des habitats situés sur des substrats ultramafiques du sud de la Nouvelle-Calédonie. Dans notre analyse génétique, trois taxons constituent un groupe bien individualisé limité à des habitats de zones d'altitude dans les massifs du sud. La spéciation à l'intérieur de ce groupe reflète probablement les contractions de la forêt vers des refuges au sommet des montagnes liées aux changements climatiques qui se sont déroulés durant l'histoire ancienne et récente du genre. Leur répartition géographique extrêmement étroite et la vulnérabilité de leurs habitats préférentiels par le feu (perte ou dégradation) et les espèces invasives rendent ces espèces d'altitude menacées et nous amènent à les ranger dans la catégorie 'Vulnérable' selon les critères de l'UICN. La nouvelle espèce décrite de la bordure nord de la région ultramafique du sud est connue seulement de deux localités, toutes deux menacées, et a été rangée dans la catégorie UICN 'En danger'. La forme révisée de Sigaloseps deplanchei, à présent restreinte principalement à la Grande Sud du sud de la Nouvelle-Calédonie, présente une sous-structuration génétique intra-spécifique régionale significative mais discrète. Une ou plusieurs populations de chaque sous-groupe de Sigaloseps deplanchei sont représentées dans des réserves naturelles provinciales, mais la majorité de la répartition géographique de chaque sous-groupe est vraisemblablement localisée dans des zones qui sont actuellement exploitées pour le nickel ou qui se situent dans des zones sous concession minière
