Taxonomic corrections and new records in vascular plants of Kyrgyzstan, 3

A series of notes on distribution, taxonomy, morphology and nomenclature of some vascular plants in Kyrgyzstan is presented. The presence of Scutellaria popovii Vved. in Talas Range is confirmed and documented with herbarium specimens, and this species is mapped. The known distributions of Galinsoga parviflora Cav. and Reseda lutea L., established invasive aliens, are documented with many new records and mapped. Eminium alberti (Regel) Engl. ex B. Fedtsch., Iris inconspicua (Vved.) T. Hall & Seisums, I. khassanovii Tojibaev et Turginov and Lagopsis flava Kar. et Kir. are reported as new to Kyrgyzstan. Astragalus testiculatus Pall., Corydalis glaucescens Regel, Morina parviflora Kar. et Kir., Pedicularis karatavica Pavlov, Tulipa turkestanica (Regel) Regel are reported as new to Talas Range, and Iris narbutii O. Fedtsch. as new to Alay Range. The distributions of Iris linifolia (Regel) O. Fedtsch. and I. narynensis O. Fedtsch. in Kyrgyzstan are verified and mapped. Iris zenaidae (Vved.) F.O. Khass. & Rakhimova is reduced to the synonymy of I. graeberiana Sealy; this species is reported as new to many territories of Western Tian-Shan. A new combination, Iris rodionenkoi (Lazkov & Naumenko) Lazkov & Sennikov is provided for Juno rodionenkoi Lazkov & Naumenko. The species known as Cephalorrhynchus polycladus (Boiss.) Kirp. is transferred to Lactuca as L. piestocarpa (Boiss.) Sennikov, comb. nov. with a new section, L. sect. Zollikoferiastrum (Kirp.) Sennikov, comb. nov.; this species is new to Kyrgyzstan

Marvel analysis of the measured high-resolution rovibrational spectra of H2S

44325 measured and assigned transitions of H$_2^{32}$S, the parent isotopologue of the hydrogen sulfide molecule, are collated from 33 publications into a single database and reviewed critically. Based on this information, rotation-vibration energy levels are determined for the ground electronic state using the Measured Active Rotational-Vibrational Energy Levels (MARVEL) technique. The ortho and para principal components of the measured spectroscopic network of H$_2^{32}$S are considered separately. The verified set of 25293 ortho- and 18778 para- H$_2^{32}$S transitions determine 3969 ortho and 3467 para energy levels. The Marvel results are compared with alternative data compilations, including a theoretical variational linelist.Comment: 39 pages, 3 figures, JQSRT, 201

A new SPS programme

A new experiemntal program to study hadron production in hadron-nucleus and nucleus-nucleus collisions at the CERN SPS has been recently proposed by the NA49-future collaboration. The physics goals of the program are: (i) search for the critical point of strongly interacting matter and a study of the properties of the onset of deconfinemnt in nucleus-nucleus collisions, (ii) measurements of correlations, fluctuations and hadron spectra at high transverse momentum in proton-nucleus collisions needed as for better understanding of nucleus-nucleus results, (iii) measurements of hadron production in hadron-nucleus interactions needed for neutrino (T2K) and cosmic-ray (Pierre Auger Observatory and KASCADE) expriments. The physics of the nucleus-nucleus program is reviewed in this presentation

The global retinoblastoma outcome study : a prospective, cluster-based analysis of 4064 patients from 149 countries

DATA SHARING : The study data will become available online once all analyses are complete.BACKGROUND : Retinoblastoma is the most common intraocular cancer worldwide. There is some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these differences have not been assessed on a global scale. We aimed to report 3-year outcomes for children with retinoblastoma globally and to investigate factors associated with survival. METHODS : We did a prospective cluster-based analysis of treatment-naive patients with retinoblastoma who were diagnosed between Jan 1, 2017, and Dec 31, 2017, then treated and followed up for 3 years. Patients were recruited from 260 specialised treatment centres worldwide. Data were obtained from participating centres on primary and additional treatments, duration of follow-up, metastasis, eye globe salvage, and survival outcome. We analysed time to death and time to enucleation with Cox regression models. FINDINGS : The cohort included 4064 children from 149 countries. The median age at diagnosis was 23·2 months (IQR 11·0–36·5). Extraocular tumour spread (cT4 of the cTNMH classification) at diagnosis was reported in five (0·8%) of 636 children from high-income countries, 55 (5·4%) of 1027 children from upper-middle-income countries, 342 (19·7%) of 1738 children from lower-middle-income countries, and 196 (42·9%) of 457 children from low-income countries. Enucleation surgery was available for all children and intravenous chemotherapy was available for 4014 (98·8%) of 4064 children. The 3-year survival rate was 99·5% (95% CI 98·8–100·0) for children from high-income countries, 91·2% (89·5–93·0) for children from upper-middle-income countries, 80·3% (78·3–82·3) for children from lower-middle-income countries, and 57·3% (52·1-63·0) for children from low-income countries. On analysis, independent factors for worse survival were residence in low-income countries compared to high-income countries (hazard ratio 16·67; 95% CI 4·76–50·00), cT4 advanced tumour compared to cT1 (8·98; 4·44–18·18), and older age at diagnosis in children up to 3 years (1·38 per year; 1·23–1·56). For children aged 3–7 years, the mortality risk decreased slightly (p=0·0104 for the change in slope). INTERPRETATION : This study, estimated to include approximately half of all new retinoblastoma cases worldwide in 2017, shows profound inequity in survival of children depending on the national income level of their country of residence. In high-income countries, death from retinoblastoma is rare, whereas in low-income countries estimated 3-year survival is just over 50%. Although essential treatments are available in nearly all countries, early diagnosis and treatment in low-income countries are key to improving survival outcomes.The Queen Elizabeth Diamond Jubilee Trust and the Wellcome Trust.https://www.thelancet.com/journals/langlo/homeam2023Paediatrics and Child Healt
