Opis:: As part of a series of studies evaluating the thermodynamic properties of new potential high energy materials, a series of calculations was performed on a variety of naphthalene molecules having amino and nitro groups. Calculations on seven aminonitronaphthalene molecules were performed, determining their minimum-energy geometries, vibrational frequencies, and energies. Enthalpies of formation were determined using atomization reactions, and subsequently enthalpies of combustion or decomposition were determined. Specific enthalpies of decomposition ranged from 4.1-4.8 kJ/g, while specific enthalpies of combustion ranged more widely, from 13 to almost 21 kJ/g. Some detonation properties of some of the derivatives rival those of current HEDMs.

Opis:: Objective: To assess the impact of reducing saturated fat or fatty foods, or replacing saturated fat with unsaturated fat, carbohydrate or protein, on the risk of mortality and major cancer and cardiometabolic outcomes in adults. Methods: We searched MEDLINE, EMBASE, CINAHL, and references of included studies for systematic reviews and meta-analyses (SRMAs) of randomized controlled trials (RCTs) and observational studies in adults published in the past 10 years. Eligible reviews investigated reducing saturated fat or fatty foods or replacing saturated fat with unsaturated fat, carbohydrate or protein, on the risk of cancer and cardiometabolic outcomes and assessed the certainty of evidence for each outcome using, for example, the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) approach. We assessed the quality of SRMAs using a modified version of AMSTAR-2. Results were summarized as absolute estimates of effect together with the certainty of effects using a narrative synthesis approach. Results: We included 17 SRMAs (13 reviews of observational studies with follow-up 1 to 34 years; 4 reviews of RCTs with follow-up 1 to 17 years). The quality of two-thirds of the SRMAs was critically low to moderate; the main limitations included deficient reporting of study selection, absolute effect estimates, sources of funding, and a priori subgroups to explore heterogeneity. Our included reviews reported > 100 estimates of effect across 11 critically important cancer and cardiometabolic outcomes. High quality SRMAs consistently and predominantly reported low to very low certainty evidence that reducing or replacing saturated fat was associated with a very small risk reduction in cancer and cardiometabolic endpoints. The risk reductions where approximately divided, some being statistically significant and some being not statistically significant. However, based on 2 moderate to high quality reviews, we found moderate certainty evidence for a small but important effect that was statistically significant for two outcomes (total mortality events [20 fewer events per 1000 followed] and combined cardiovascular events [16 fewer per 1000 followed]). Conversely, 4 moderate to high quality reviews showed very small effects on total mortality, with 3 of these reviews showing non-statistically significant mortality effects. Conclusion: Systematic reviews investigating the impact of SFA on mortality and major cancer and cardiometabolic outcomes almost universally suggest very small absolute changes in risk, and the data is based primarily on low and very low certainty evidence.

Opis:: An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for the next generation of high-energy experiments. This whitepaper summarizes the status and future prospects for determination of high-precision PDFs applicable in a wide range of energies and experiments, in particular in precision tests of the Standard Model and in new physics searches at the high-luminosity Large Hadron Collider and Electron–Ion Collider. We discuss the envisioned advancements in experimental measurements, QCD theory, global analysis methodology, and computing that are necessary to bring unpolarized PDFs in the nucleon to the N2LO and N3LO accuracy in the QCD coupling strength. Special attention is given to the new tasks that emerge in the era of the precision PDF analysis, such as those focusing on the robust control of systematic factors both in experimental measurements and theoretical computations. Various synergies between experimental and theoretical studies of the hadron structure are explored, including opportunities for studying PDFs for nuclear and meson targets, PDFs with electroweak contributions or dependence on the transverse momentum, for incisive comparisons between phenomenological models for the PDFs and computations on discrete lattice, and for cross-fertilization with machine learning/AI approaches.

Opis:: Sarcosoma globosum (witches cauldron) is a threatened species of pezizomycete (Ascomycete) fungus primarily documented in spruce (Picea spp.) forests of northern Europe. Sporadic reports of S. globosum have been reported in eastern North America, but it has been suggested that these may have been misidentified. Importantly, the species has not been officially reported in western North America. Following reported observations of S. globosum in British Columbia, Canada, we conducted a citizen science survey to document its distribution and occurrence over four consecutive years (2021–2024). Firstly, we verified that sporocarps collected in eastern (New Brunswick) and western (British Columbia) Canada were S. globosum via the morphological, ecological, and phylogenetic (analysis of the ITS gene) species concepts. Secondly, S. globosum was documented in all four years of the survey over a wide geographical area in British Columbia. Finally, we mapped the Canadian distribution of S. globosum based on publicly available databases. The species appears to be found across Canada (British Columbia to Nova Scotia), where spruce-dominated forests are present, supporting the current Canadian national conservation status of ‘Apparently Secure/Secure’ (N4, N5). However, its habitat remains threatened by climate change, forest fires, and logging activities that may limit its future geographical distribution. This study presents the first documented occurrence of S. globosum in British Columbia, expanding the species’ known distribution to western Canada.
