Reproductive seasonality and fecundity of the spiny lobsterPanulirus homarus homarus(Linnaeus, 1758) (Decapoda: Achelata: Palinuridae) in Kenya: implications for sustainable management
Authors: Kulmiye Abdirahman J 
Published: May 2022

AbstractThe scalloped spiny lobster Panulirus homarus homarus (Linnaeus, 1758) is one of the most commercially important lobsters exploited in Kenya. Despite its local importance and wide distribution, detailed knowledge on its reproduction in East Africa is lacking. The study reported herein sought to determine its spawning season based on seasonal variations in female gonadosomatic index (GSI), temporal distribution of ovarian maturity stages, and the proportion of ovigerous females in the monthly samples captured off Mambrui, Kenya. The study also assessed size composition, sex ratio, fecundity, and reproductive potential. A total of 2,454 lobsters were collected during the study period (January 2000-December 2001), covering a size range of 26–115 mm carapace length (CL). Neither the overall sex ratio nor the monthly sex distributions deviated significantly from the expected ratio of 1:1, except for a few months when males and females alternately dominated the samples with no discernible seasonal trends. Analysis of the cyclical changes in reproductive activity shows strong spawning seasonality in synchrony with the Northeast monsoon season in both years. Simultaneous breeding of a wide size range of females (54–90 mm CL) commenced in November and intensified over the following months until April. Outside the Northeast monsoon season, only 10 females, out of the total 517 sexually mature females sampled during the 2000 and 2001 Southeast monsoon seasons, bore eggs, and all were large individuals (&gt;66 mm CL) encountered in the 2001 samples. Fecundity was positively and linearly related to female size (CL) and best described by the equation E = 10,400 CL – 472,040 (R2 = 0.929, N = 59). Estimated fecundity varied between 81,000 and 474,000 eggs per spawn in female lobsters (54 mm–91 mm CL). Female lobsters between 66 mm and 80 mm CL contributed 62% of the estimated total egg production of the population. The widespread retention of egg-bearing females in a fishery where the main fishing season falls during the spawning season, can have detrimental effects on the spawning stock abundance and egg production with increased risk of recruitment failure and stock collapse.

AbstractThe white-backed planthopper, WBPH, Sogatella furcifera (Horváth) is a plant pest that migrates long-distances. The migration pathway of WBPH in eastern China coincides with the north-south round trip of the East Asian monsoon. However, in Yunnan China, which is affected by two monsoon systems, the migration pathway is unclear. Light-trap data and analysis of female ovarian development showed that the peak period of immigration of WBPH into western Yunnan was earlier than in eastern Yunnan. Using meteorological reanalysis data and flight parameters of WBPH, trajectory modeling showed that there are two immigration pathways to Yunnan. One is from Myanmar to western Yunnan, and the other is from Vietnam and Laos to eastern Yunnan. The reason for the differences in source areas and immigration pathways between eastern and western Yunnan is that the west wind prevails in western Yunnan and is controlled by South Asian monsoon, while southwesterly winds prevail in eastern Yunnan due to the combined influence of South Asian monsoon and East Asian monsoon. The results indicate that WBPH invades Yunnan via two pathways under a two-monsoon system. These data will allow earlier prediction and population management of WBPH.
‘The illustration of all art expressed in objects of utility’: The formation of the Renaissance collections at the Victoria and Albert Museum
Authors: Evans Mark 
Published: May 2022

Abstract
This article examines the formation of the collections of fifteenth- and sixteenth-century European works of art at the Victoria and Albert Museum. For brevity’s sake, all are characterized here as ‘Renaissance’ objects, rather than by their century of production. During the first quarter-century of the museum’s activity, Renaissance art was a powerful conditioning influence on British culture and society. This encouraged the growth of the Renaissance collections between 1852 and 1875 at a rapid rate that has never since been equalled. The museum’s regularly published inventories of acquisitions include the prices paid for objects; since the purchasing power of the pound sterling altered little between 1854 and 1914, this permits an assessment of the relative value of acquisitions over this formative period. The paper closes with a résumé of the continued development of the collections since the First World War.
A Review ofBartonellaInfections in California—Implications for Public and Veterinary Health
Authors: Billeter Sarah A 
Published: May 2022

AbstractBartonella are vector-transmitted, intracellular bacteria that infect a wide variety of blood-feeding arthropods and their vertebrate hosts. In California, more than 13 species of Bartonella have been described from companion animals, livestock, and wildlife, of which four have been associated with human disease. Infections in humans cause a range of symptoms from relatively mild to severe, especially in immunocompromised individuals. Exposure to infected domestic animals and wildlife, and their ectoparasites, may increase the risk of cross-species transmission. The objective of this review was to compile and summarize published materials on human and animal Bartonella infections in California. Medical and veterinary case reports of bartonellosis were highlighted in an effort to increase the awareness of this poorly understood and potentially under-recognized disease among healthcare professionals and veterinarians.
Provisional Measures after Ukraine v Russia (2022)
Authors: Kulick Andreas 
Published: May 2022

Abstract
On 16 March 2022, among others measures, the International Court of Justice (ICJ) ordered the Russian Federation to suspend immediately its military operations in Ukraine. The Order is remarkable for several reasons and, so it is submitted, potentially will entail considerable consequences in international adjudication, before and beyond the ICJ, as well as with respect to international law at large. In international procedural law, it emphasizes the vastness of what parties to international proceedings can ask for and what an international court or tribunal can order in respect of provisional measures. However, possibly the strongest potential of the Order does not lie in what it enables, but what it disables: it may deter states that are not a permanent member of the United Nations Security Council from employing insincere human rights arguments as a pretext for a military intervention in a neighbouring state.
Constraining low redshift [C II] emission by cross-correlating FIRAS and BOSS data
Authors: Anderson C J , Switzer E R , Breysse P C 
Published: May 2022

ABSTRACT
We perform a tomographic cross-correlation analysis of archival FIRAS data and the BOSS galaxy redshift survey to constrain the amplitude of [C II] 2P3/2 → 2P1/2 fine structure emission. Our analysis employs spherical harmonic tomography (SHT), which is based on the angular cross-power spectrum between FIRAS maps and BOSS galaxy over-densities at each pair of redshift bins, over a redshift range of 0.24 &lt; z &lt; 0.69. We develop the SHT approach for intensity mapping, where it has several advantages over existing power spectral estimators. Our analysis constrains the product of the [C II] bias and [C II] specific intensity, $b_{\rm [C \small{\rm II}]}I_{\rm [C \small{\rm II}]}$, to be &lt;0.31 MJy/sr at z ≈ 0.35 and &lt;0.28 MJy/sr at z ≈ 0.57 at $95{{\ \rm per\ cent}}$ confidence. These limits are consistent with most current models of the [C II] signal, as well as with higher-redshift [C II] cross-power spectrum measurements from the Planck satellite and BOSS quasars. We also show that our analysis, if applied to data from a more sensitive instrument such as the proposed PIXIE satellite, can detect pessimistic [C II] models at high significance.

ABSTRACT
The magnetar SGR J1935+2154 underwent a new active episode on 2020 April 27–28, when a forest of hundreds of X-ray bursts and a large enhancement of the persistent flux were detected. For the first time, a radio burst with properties similar to those of fast radio bursts and with a X-ray counterpart was observed from this source, showing that magnetars can power at least a group of fast radio bursts. In this paper, we report on the X-ray spectral and timing properties of SGR J1935+2154 based on a long-term monitoring campaign with Chandra, XMM–Newton, NuSTAR, Swift, and NICER covering a time-span of ∼7 months since the outburst onset. The broad-band spectrum exhibited a non-thermal power-law component (Γ ∼ 1.2) extending up to ∼20–25 keV throughout the campaign and a blackbody component with temperature decreasing from ∼1.5 keV at the outburst peak to ∼0.45 keV in the following months. We found that the luminosity decay is well described by the sum of two exponential functions, reflecting the fast decay (∼1 d) at the early stage of the outburst followed by a slower decrease (∼30 d). The source reached quiescence about ∼80 d after the outburst onset, releasing an energy of ∼6 × 1040 erg during the outburst. We detected X-ray pulsations in the XMM–Newton data sets and derived an average spin-down rate of ∼3.5 × 10−11 s s−1 using the spin period measurements derived in this work and three values reported previously during the same active period. Moreover, we report on simultaneous radio observations performed with the Sardinia Radio Telescope. No evidence for periodic or single-pulse radio emission was found.

ABSTRACT
Numerical general relativistic radiative magnetohydrodynamic simulations of accretion discs around a stellar-mass black hole with a luminosity above 0.5 of the Eddington value reveal their stratified, elevated vertical structure. We refer to these thermally stable numerical solutions as puffy discs. Above a dense and geometrically thin core of dimensionless thickness h/r ∼ 0.1, crudely resembling a classic thin accretion disc, a puffed-up, geometrically thick layer of lower density is formed. This puffy layer corresponds to h/r ∼ 1.0, with a very limited dependence of the dimensionless thickness on the mass accretion rate. We discuss the observational properties of puffy discs, particularly the geometrical obscuration of the inner disc by the elevated puffy region at higher observing inclinations, and collimation of the radiation along the accretion disc spin axis, which may explain the apparent super-Eddington luminosity of some X-ray objects. We also present synthetic spectra of puffy discs, and show that they are qualitatively similar to those of a Comptonized thin disc. We demonstrate that the existing xspec spectral fitting models provide good fits to synthetic observations of puffy discs, but cannot correctly recover the input black hole spin. The puffy region remains optically thick to scattering; in its spectral properties, the puffy disc roughly resembles that of a warm corona sandwiching the disc core. We suggest that puffy discs may correspond to X-ray binary systems of luminosities above 0.3 of the Eddington luminosity in the intermediate spectral states.
Influence of dark matter on gravitational stability of isothermal gas clouds
Authors: Kalashnikov I Yu , Chechetkin V M 
Published: May 2022

ABSTRACT
To date, the presence of dark matter (DM) can be judged only by its gravitational interaction on the visible matter. It is therefore important to find the consequences of this interaction, which can then help to determine both the DM properties and parameters and the dynamics and evolution of visible matter. The gravitational influence of dark matter on the stability of interstellar medium (ISM), the progenitor of stars and star clusters, was considered. An isothermal self-gravity gas was taken as a suitable model describing ISM, particles interacting only gravitationally were considered as DM. The results obtained by analytical methods show that even a small amount of fast DM particles significantly increases the stable radius of the gas cloud and the corresponding mass while a higher relative density of DM destabilizes the gas. It was shown that with typical parameters of ISM and DM, its presence increases the maximum stable mass of isothermal cloud by a factor of 4 and the radius by five.

Abstract
Dissecting the underlying structure of galaxies is of main importance in the framework of galaxy formation and evolution theories. While a classical bulge+disc decomposition of disc galaxies is usually taken as granted, this is only rarely solidly founded upon the full exploitation of the richness of data arising from spectroscopic studies with integral field units. In this work we describe a fully Bayesian estimation method of the global structure of disc galaxies which makes use of the wealth of photometric, kinematic, and mass-to-light ratio data, and that can be seen as a first step towards a machine-learning approach, certainly needed when dealing with larger samples of galaxies. Ours is a novel, hybrid line of action in tackling the problem of galactic parameter estimation, neither purely photometric nor orbit-based. Being rooted on a nested sampler, our code, which is available publicly as an online repository , allows for a statistical assessment of the need for multiple components in the dissecting process. As a first case-study the GPU-optimized code is applied to the S0 galaxy NGC-7683, finding that in this galaxy a pseudo-bulge, possibly the remnant of a bar-like structure, does exist in the center of the system. These results are then tested against the publicly available, orbit-based code DYNAMITE, finding substantial agreement.

ABSTRACT

Objectives
Behçet’s disease (BD) is a systemic vasculitis affecting many organ systems, with the involvement of all-sized arteries and veins. The study aims to determine the main characteristics of paediatric BD patients and also analyse the clustering phenotypes.

Methods
Demographic data, clinical manifestations, laboratory features, treatment schedules, and disease outcomes were achieved from patients’ charts retrospectively. A cluster analysis was performed according to the phenotype.

Results
A total of 225 (109 male/116 female) patients with BD were enrolled in the study. The median ages of disease onset and diagnosis were 131 (36–151) and 156 (36–192) months, respectively. According to cluster analysis, 132 (58.6%) patients belonged to the mucocutaneous-only cluster (C1), while 35 (15.6%) patients fitted to articular type (C2), 25 (11.1%) were in the ocular cluster (C3), 26 (11.6%) were in the vascular cluster (C4), and 7(3.1%) belonged to the gastrointestinal cluster (C5). Ocular and vascular clusters were more common in boys (p &lt; .001), while girls usually presented with the mucocutaneous-only cluster. The disease activity at the diagnosis and the last control was higher in ocular, vascular, and gastrointestinal clusters.

Conclusions
These identified juvenile BD clusters express different phenotypes with different outcomes Our analysis may help clinicians to identify the disease subtypes accurately and to arrange personalized treatment.

ABSTRACT
Short stature is a common clinical condition in paediatric outpatient clinics and is associated with various clinical conditions, ranging from normal variants to severe diseases. Short stature is known to be caused by chronic inflammatory conditions, in which over-produced inflammatory cytokines are reported to be involved in growth suppression. Castleman disease is a rare lymphoproliferative disorder known as a chronic inflammatory disease with overproduction of interleukin 6, which often causes systemic symptoms such as fever, fatigue, weight loss, and night sweats. Here, we report the case of a 10-year-old female diagnosed with unicentric Castleman disease, who presented with short stature as the sole clinical sign but lacked typical systemic symptoms of Castleman disease. An elevated serum C-reactive protein level led us to suspect a chronic inflammatory condition, and we found an intra-abdominal tumour that was histopathologically confirmed as Castleman disease. The tumour removal resulted in a steady catch-up in her height in the six years following the surgery. We also present a brief review of relevant literature on paediatric cases of Castleman disease associated with growth impairment. Clinicians should be aware that chronic inflammatory conditions can cause growth impairment, which may be a key clinical manifestation of such conditions.

Abstract
Circular dichroism (CD) spectroscopy is widely used to characterize the secondary structure composition of proteins. To derive accurate and detailed structural information from the CD spectra, we have developed the Beta Structure Selection (BeStSel) method (PNAS, 112, E3095), which can handle the spectral diversity of β-structured proteins. The BeStSel webserver provides this method with useful accessories to the community with the main goal to analyze single or multiple protein CD spectra. Uniquely, BeStSel provides information on eight secondary structure components including parallel β-structure and antiparallel β-sheets with three different groups of twist. It overperforms any available method in accuracy and information content, moreover, it is capable of predicting the protein fold down to the topology/homology level of the CATH classification. A new module of the webserver helps to distinguish intrinsically disordered proteins by their CD spectrum. Secondary structure calculation for uploaded PDB files will help the experimental verification of protein MD and in silico modelling using CD spectroscopy. The server also calculates extinction coefficients from the primary sequence for CD users to determine the accurate protein concentrations which is a prerequisite for reliable secondary structure determination. The BeStSel server can be freely accessed at https://bestsel.elte.hu.

Abstract
Emerging single-cell technologies provide high-resolution measurements of distinct cellular modalities opening new avenues for generating detailed cellular atlases of many and diverse tissues. The high dimensionality, sparsity, and inaccuracy of single cell sequencing measurements, however, can obscure discriminatory information, mask cellular subtype variations and complicate downstream analyses which can limit our understanding of cell function and tissue heterogeneity. Here, we present a novel pre-processing method (scPSD) inspired by power spectral density analysis that enhances the accuracy for cell subtype separation from large-scale single-cell omics data. We comprehensively benchmarked our method on a wide range of single-cell RNA-sequencing datasets and showed that scPSD pre-processing, while being fast and scalable, significantly reduces data complexity, enhances cell-type separation, and enables rare cell identification. Additionally, we applied scPSD to transcriptomics and chromatin accessibility cell atlases and demonstrated its capacity to discriminate over 100 cell types across the whole organism and across different modalities of single-cell omics data.
Measuring quality of life in trials including patients on haemodialysis: methodological issues surrounding the use of the Kidney Disease Quality of Life Questionnaire

ABSTRACTBackgroundHaemodialysis (HD) treatment causes a significant decrease in quality of life (QoL). When enrolled in a clinical trial, some patients are lost prior to follow-up because they die or they receive a kidney transplant. It is unclear how these patients are dealt with in the analysis of QoL data. There are questions surrounding the consistency of how QoL measures are used, reported and analysed.MethodsA systematic search of electronic databases for trials measuring QoL in HD patients using any variation of the Kidney Disease Quality of Life (KDQoL) Questionnaire was conducted. The review was conducted in Covidence version 2. Quantitative analysis was conducted in Stata version 16.ResultsWe included 61 trials in the review, of which 82% reported dropouts. The methods to account for missing data due to dropouts include imputation (7%) and complete case analysis (72%). Few trials (7%) conducted a sensitivity analysis to assess the impact of missing data on the study results. Single imputation techniques were used, but are only valid under strong assumptions regarding the type and pattern of missingness. There was inconsistency in the reporting of the KDQoL, with many articles (70%) amending the validated questionnaires or reporting only statistically significant results.ConclusionsMissing data are not dealt with according to the missing data mechanism, which may lead to biased results. Inconsistency in the use of patient-reported outcome measures raises questions about the validity of these trials. Methodological issues in nephrology trials could be a contributing factor to why there are limited effective interventions to improve QoL in this patient group.PROSPERO RegistrationCRD42020223869
