AbstractStriga is one of most notorious weeds devastating crop production in the dry savannas of northern Nigeria. The weed attacks most cultivated cereals and legumes with crop losses as high as 100% when no control measure is employed. Studies conducted in the dry savannas of Nigeria indicated that Striga seedbank is strongly related to soil and climate properties. This study was conducted to model Striga hermonthica seedbank zones in the dry savannas of Nigeria based on soil and climate properties of the areas. Using multi‐stage spatial sampling, 169 soil samples were collected at the centroids of 25 × 25 km grids across the study area and analysed for physico‐chemical properties. The number of Striga seeds were counted from the soil samples using water elutriator and potassium bicarbonate method. Daily temperature, relative humidity and rainfall for each point were downloaded from Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS). Minimum and maximum temperatures, and relative humidity were accessed from National Aeronautics and Space Administration (NASA POWER). Thresholds of various soil and climate variables for optimum concentration of Striga seedbank were analysed using boundary line analysis (BLA). From the BLA, optimum amount of rainfall for high Striga seedbank was 549 mm per annum. While temperature has a wide suitability range for Striga seedbank development. Principal component analysis was used to reduce dimensionality of the dataset into principal components (PCs). Seven PCs which explained 75.6% variation in the data were retained and used in the weighed overlay modelling (WOM). The weighted overlay map produced five distinct Striga seedbank zones; very low, low, moderate, high and very high. More than 60% of the study area had moderate to high Striga seedbanks. The zones vary mostly based on soil, climate and Striga seed count. The establishment of the optimum levels of the environmental factors at which Striga seedbank is favoured will assist in designing a more site‐specific Striga management. However, for scalability purpose, adoption of the Striga zoning approach can be useful.

AbstractLet be a point set with cardinality . We give an improved bound for the number of dot products determined by , proving that
A crucial ingredient in the proof of this bound is a new superquadratic expander involving products and shifts. We prove that, for any finite set , there exist such that
This is derived from a more general result concerning growth of sets defined via convexity and sum sets, and which can be used to prove several other expanders with better than quadratic growth. The proof develops arguments from Hanson, Roche‐Newton, and Rudnev [Combinatorica, to appear], and uses predominantly elementary methods.

Authors: Meyer Sarah R. , Lasater Molly E. , Lee Lindsay , Garcia-Moreno Claudia 
Published: February 2023

IntroductionViolence against women is a serious threat to women’s health and human rights globally. Disability has been associated with increased risk of exposure to different forms of violence, however, there are questions concerning how best to measure this association. Research on understanding the association between violence and disability among women has included incorporating short disability measures into violence against women prevalence surveys. The potential to improve understanding of interconnections between violence and disability by measuring violence within disability-focused research is underexplored. The scoping review described here focuses on three areas of measurement of violence against women and disability: (1) measurement of violence within the context of disability-focused research, (2) measurement in research focused on the intersection of disability and violence and (3) measurement of disability in the context of research focused on violence against women. Specifically, we aim to map definitions, measures and methodologies in these areas, globally.Methods and analysisFor our scoping review, we will conduct searches for quantitative studies of disability-focused research which use measures of violence against women, and measures of disability in research focused on violence against women, in 11 online databases. Two authors will independently review titles and abstracts retrieved through the search strategy. We will search for grey literature, search the websites of National Statistics Offices for all countries to identify any national or subnational disability research and consult with experts for input. Data extraction will be conducted independently by one author and reviewed by another author, and data will be analysed and synthesised using a thematic synthesis approach.Ethics and disseminationEthics approval was not sought as no primary data is being collected. Findings will be disseminated through a publication in a peer-reviewed journal, through coordinated dissemination to researchers, practitioners, data users and generators and through various working groups and networks on violence against women and disability.

ObjectivesThis study evaluated the relationship between status of oral function and related long-term care service costs.DesignThis was a prospective 6-year follow-up study of previous survey data.SettingThe data were obtained from the Japan Gerontological Evaluation Study conducted between 2010 and 2011.ParticipantsThe participants were functionally independent older adults in 12 municipalities across Japan.InterventionsCare service benefit costs were tracked over 6 years using publicly available claims records (n=46 616) to monitor respondents’ cumulative care costs.Primary and secondary outcome measuresThe primary outcome variable was the cumulative cost of long-term care insurance services during the follow-up period. We adjusted for the presence or absence of oral function problems, age, sex, physical function and socioeconomic and lifestyle background at the time of the baseline survey.ResultsTobit analysis revealed that, compared with those with no oral function problems, cumulative long-term care service benefit costs for those with one, two or three oral function problems were approximately US$4020, US$4775 and US$82 92, respectively, over 6 years. Compared with those with maintained oral function, there was a maximum difference of approximately US$8292 in long-term care service costs for those with oral function problems. With increase in number of oral function problems, there was a concomitant elevation in the cost of long-term care.ConclusionsOral function in older people was associated with cumulative long-term care insurance costs. The oral function of older people should be maintained to reduce future accumulated long-term care insurance costs. Compared with those with maintained oral function, there was a maximum difference of approximately US$8292 in long-term care service costs for those with oral function problems. The cost of long-term care was amplified as oral problems increased.

ObjectiveTo identify the approaches and strategies used for ensuring cultural appropriateness, intervention functions and theoretical constructs of the effective and ineffective school-based smoking prevention interventions that were implemented in low-income and middle-income countries (LMICs).Data sourcesIncluded MEDLINE, EMBASE, Global Health, PsycINFO, Web of Science and grey literature which were searched through August 2022 with no date limitations.Eligibility criteriaWe included randomised controlled trials (RCTs) with ≥6 months follow-up assessing the effect of school-based interventions on keeping pupils never-smokers in LMICs; published in English or Arabic.Data extraction and synthesisIntervention data were coded according to the Theoretical Domains Framework, intervention functions of Behaviour Change Wheel and cultural appropriateness features. Using narrative synthesis we identified which cultural-adaptation features, theoretical constructs and intervention functions were associated with effectiveness. Findings were mapped against the capability-motivation and opportunity model to formulate the conclusion. Risk of bias was assessed using the Cochrane risk of bias tool.ResultsWe identified 11 RCTs (n=7712 never-smokers aged 11–15); of which five arms were effective and eight (four of the effective) arms had a low risk of bias in all criteria. Methodological heterogeneity in defining, measuring, assessing and presenting outcomes prohibited quantitative data synthesis. We identified nine components that characterised interventions that were effective in preventing pupils from smoking uptake. These include deep cultural adaptation; raising awareness of various smoking consequences; improving refusal skills of smoking offers and using never-smokers as role models and peer educators.ConclusionInterventions that had used deep cultural adaptation which incorporated cultural, environmental, psychological and social factors, were more likely to be effective. Effective interventions considered improving pupils’ psychological capability to remain never-smokers and reducing their social and physical opportunities and reflective and automatic motivations to smoke. Future trials should use standardised measurements of smoking to allow meta-analysis in future reviews.

AimTo investigate the prevalence and factors associated with optic disc grey crescent (GC) in African Americans with glaucoma.MethodsStereo optic disc image features from subjects with glaucoma in the Primary Open-Angle African Ancestry Glaucoma Genetics Study were evaluated independently by non-physician graders and discrepancies adjudicated by an ophthalmologist. Risk factors for GC were evaluated by logistic regression models with intereye correlation accounted for by generalised estimating equations. Adjusted ORs (aORs) were generated.ResultsGC was present in 227 (15%) of 1491 glaucoma cases, with 57 (3.82%) bilateral and 170 (11.4%) unilateral. In multivariable analysis, factors associated with GC were younger age (aOR 1.27, 95% CI 1.11 to 1.43 for every decade younger in age, p=0.001), diabetes (aOR 1.46, 95% CI 1.09 to 1.96, p=0.01), optic disc tilt (aOR 1.84, 95% CI 1.36 to 2.48, p<0.0001), a sloping retinal region adjacent to the outer disc margin (aOR 2.37, 95% CI 1.74 to 3.32, p<0.0001) and beta peripapillary atrophy (aOR 2.32, 95% CI 1.60 to 3.37, p<0.0001). Subjects with GC had a lower mean (SD) value of the ancestral component q0 than those without GC (0.22 (0.15) vs 0.27 (0.20), p=0.001), consistent with higher degrees of African ancestry.ConclusionsMore than 1 in 10 glaucoma cases with African ancestry have GC, occurring more frequently in younger subjects, higher degrees of African ancestry and diabetes. GC was associated with several ocular features, including optic disc tilt and beta peripapillary atrophy. These associations should be considered when evaluating black patients with primary open-angle glaucoma.

Published: February 2023

ObjectiveTo assess the finger vascularity of systemic sclerosis patients with Raynaud’s phenomenon (RP-SSc) using various ultrasound techniques.MethodsAll fingers (except thumbs) of 18 RP-SSc patients and 18 controls were imaged at room temperature using four ultrasound vascular imaging techniques. The percent vascular area was quantified by counting blood flow pixels in a 25 mm2square centred at the nail fold for the dorsal side and in 25 mm2and 100 mm2square from the fingertip for the ventral side. The mean vascular intensity was calculated from the corresponding areas for dorsal and ventral sides.ResultsThe percent vascular areas and mean vascular intensities in RP-SSc were significantly lower than those in controls for both dorsal and ventral sides (p<0.01). The mean vascular intensities showed slightly higher area under the curve (AUC) than the percent vascular areas (0.53–0.91 vs 0.53–0.90) regardless of imaging technique and assessment side. For each imaging technique, the ventral side vascularity showed a higher AUC (0.74–0.91) compared with the dorsal side (0.53–0.81). Moreover, ventral side abnormalities were associated with a history of digital ulcers.ConclusionsUltrasound demonstrated potential to quantify finger vascularity of RP-SSc. The ventral side of the fingers showed a higher accuracy in detecting RP-SSc than the dorsal side.

Self-Organization Phenomena
Authors: Sienkiewicz Rafał , Jędruch Wojciech 
Published: February 2023

Abstract
The article presents the DigiHive system, an artificial chemistry simulation environment, and the results of preliminary simulation experiments leading toward building a self-replicating system resembling a living cell. The two-dimensional environment is populated by particles that can bond together and form complexes of particles. Some complexes can recognize and change the structures of surrounding complexes, where the functions they perform are encoded in their structure in the form of Prolog-like language expressions. After introducing the DigiHive environment, we present the results of simulations of two fundamental parts of a self-replicating system, the work of a universal constructor and a copying machine, and the growth and division of a cell-like wall. At the end of the article, the limitations and arising difficulties of modeling in the DigiHive environment are presented, along with a discussion of possible future experiments and applications of this type of modeling.

Published: February 2023

Abstract
This article discusses the foundation of Studio PANaroma de Música Eletroacústica in São Paulo in 1994, an institution of the São Paulo State University and one of the most active research and production centers in the area in the world, contextualizing its conception with the internationalist tendencies present since the beginning of modernism in Brazil. To this end, the text discusses the notion of cultural anthropophagy, as formulated by Oswald de Andrade; discusses a brief history of the first initiatives in the field of electroacoustic music in Brazil; and focuses on the historical importance and the particularity of the Studio PANaroma, which substantially changed the development of electroacoustic music in the country. The studio's activities are described, including the founding of the studio's loudspeaker orchestra, as well as the studio's main research activities.

Abstract
Different types of stress produce different effects on social relationships between partners. Chronic social defeat has been found to alter the emotional and social behaviours, whether it affects partner preference remains unclear. Using monogamous mandarin voles (Microtus mandarinus), the present study found that 14 days of social defeat to male vole could increase social avoidance in sociality test, and reduced attacking, intimate, sniffing and exploratory behaviours, but increased avoidance defensive, immobile behaviours in social interaction test. In addition, this treatment significantly reduced side-by-side contact with partner throughout cohabitation period, and reduced the attacking behaviour to strangers after 11 days’ cohabitation. Furthermore, in mandarin vole with chronic social defeat, partner preference was abolished on 5 and 7 days’ cohabitation indicating that pair bonding stability was impaired by chronic social defeat. Moreover, although mandarin voles spent longer time rescuing partner than stranger in both groups, chronic social defeat did not affect rescuing significantly. Impairment of pair bonding may be due to abnormalities in social interaction induced by chronic social defeat. This finding provides some insights into mechanisms underlying effects of prolong social stress on social relationships between partners.

Abstract
The Tibetan Plateau (TP) with a large landmass serves as an obstacle that hinders westerly flows and alters climate downwind. Here, we investigate the TP influence on the magnitude and spatial distribution of wintertime fine particulate matter (PM2.5) concentrations downwind and associated underlying mechanisms. Based on simulations using an Earth system model, we show that the removal of the TP would reduce surface PM2.5 concentrations by −30.4% in the Sichuan basin (SC) and by −12.4% in the North China Plain (NCP), but increase the concentrations by 18.1% in eastern China (EC), suggesting that the TP could naturally intensify PM2.5 pollution in SC and NCP. If the TP were absent, more meridional circulations would turn into zonal ones and the East Asian winter monsoon would become weaker. There would be less precipitation and lower humidity over SC and EC in the south, while the opposite occurs over NCP in the north. Consequently, the changes in circulations would result in a net outflow of PM2.5 from SC and NCP, but a net inflow of PM2.5 to EC. In response to the spatial changes in precipitation, wet deposition would decrease in SC and EC but increase in NCP. PM2.5 production would reduce in SC and EC but amplify in NCP, following the changes in humidity. In magnitude, the changes in transport and wet deposition would be dominant in SC and NCP, while in EC, transport, wet deposition, and chemical production would be equally important. This study illustrates significant and heterogeneous impacts of the TP on air quality downwind.
Understanding the Variation and Mechanisms of Tropical Cyclone Genesis Potential over the Western North Pacific during the Past 20 000 Years

Abstract
To deepen our understanding of the behavior of tropical cyclones (TCs) over the western North Pacific (WNP) and its response to various external forcings, we investigate the variation of TC genesis potential over the WNP during the past 20 ka that experienced several large forcings. Using a set of transient simulations and a genesis potential index, our results indicate that TC genesis potential in the storm season shows an overall increase averaged over the WNP during the Heinrich Stadial 1 (HS1; ∼17–16 ka) relative to the Last Glacial Maximum. Subsequently, there is a sharp decrease in genesis potential during the Bølling–Allerød (BA; ∼13.5 ka) relative to the HS1, which is followed by an increase during the Younger Dryas (YD; ∼12.9–11.7 ka). During the Holocene, TC genesis potential shows a slight decrease during the early–middle Holocene (∼11.7–6 ka) and a significant increasing trend afterward. Further analysis shows that the contribution of each genesis factor to the genesis potential change varies greatly with time, which is in turn tied to changes in external forcings. The increased meltwater fluxes dominate the increased genesis potential during the HS1 and YD, whereas all external forcings (i.e., changes in meltwater, ice sheets, CO2, and insolation) contribute to genesis potential change during the BA. The long-term increasing trend from the mid-Holocene to the present is controlled by orbital insolation. These results may help improve our understanding on past TC activity and shed lights on TC response to various external forcings in a long-term future.
