AbstractIce aprons are defined as very small ice bodies covering steep rock slopes. They have only been the subject of increased scientific interest for a few years, despite the fact that they are a condition for mountaineering and obvious elements in the high-alpine landscapes. However, very little is known about their distribution, evolution and physical characteristics. In this paper, we review the existing knowledge on ice aprons, which have almost exclusively been investigated in the Mont-Blanc massif, Western Alps. We supplement this review with novel results from recent surveys of ice aprons. We used a wide array of methodologies, from remote sensing (multi-source imagery) to in situ (stakes and thermal monitoring) and laboratory (radiocarbon dating and texture analysis) glaciological investigations. In the Mont-Blanc massif, ice aprons occupy 4.2 km2 within the alpine permafrost zone. Temperature measured at the ice–rock interface is indeed largely negative. Thinness of ice aprons coupled with the cold context implies a quasi-stationary shear regime without basal Sliding. Only ice at the surface can possibly melt in warm periods. After a shrinking period from the end of the Little Ice Age to the mid-to-late-1960s, ice aprons experienced a short period of expansion, followed by an accelerated shrinkage since the beginning of the 21st century. This shrinkage now favours rockfall triggering and poses a serious threat to a glaciological heritage since ice aprons host several-thousand-year-old ice. Finally, we synthesize this information to assess the existing definition of ice aprons, and propose some future research directions.

Stages of capitalist development and maximum marine plastic pollution
Authors: Jacques Peter J. 
Published: May 2023

Abstract
Marine plastic pollution (MPP) has become ubiquitous in the oceans and is damaging human health, ecosystems, and economies which has resulted in a mandate for a new binding plastics treaty. What would an effective treaty look like? What explains this relatively new global crisis? This review article argues that the work of Karl Polanyi and stage theory can put the MPP problem into context and illuminate requirements of an effective treaty. Polanyi argued that if market society did not restrain the capitalist use of land (nature), labor, and money it would destroy itself and MPP will only be solved if these social and environmental protections restrain capital. Stage theory looks at the evolving expressions of capitalism in distinct historical periods to provide context for the global economy and implies a structural remedy for the plastics in the ocean. In particular, the post-War Fordist stage introducing mass production and the following post-Fordist neoliberal period witnessed progressively thinned restraints on capital and the global plastic flow is a function of these changes over time resulting in continuously increasing MPP.
Tapping into natural history collections to assess latitudinal gradients of parasite diversity
Authors: Botero-Cañola Sebastian , Gardner Scott L. 
Published: May 2023

AbstractParasites are key components of the biosphere not only due to their huge diversity, but also because they exert important influences on ecological processes. Nevertheless, we lack an understanding of the biogeographical patterns of parasite diversity. Here, we tap into the potential of biodiversity collections for understanding parasite biogeography. We assess species richness of supracommunities of helminth parasites infecting mammal assemblages in the Nearctic, and describe its relation to latitude, climate, host diversity, and land area. We compiled data from parasitology collections and assessed parasite diversity in Nearctic ecoregions for the entire parasite supracommunity of mammals in each ecoregion, as well as separately from carnivores and rodents to explore the effect of host taxonomic resolution on observed patterns. For carnivores, we found evidence of a negative latitudinal gradient, while parasites of rodents displayed no clear pattern. We found that parasite diversity was positively correlated with mean annual temperature and negatively correlated with seasonal precipitation. Parasite richness shows a diversity peak at intermediate host richness values and in carnivores correlates with temperature and seasonal precipitation. Rodent parasite diversity did not correlate with explored factors. Other researchers are encouraged to use parasitology collections to continue exploring patterns of parasite biogeography and macroecology.

Published: May 2023

AbstractStylops ateris an endoparasite of the mining beeAndrena vagawith extreme sexual dimorphism and hypermetamorphosis. Its population structure, parasitization mode, genetic diversity and impact on host morphology were examined in nesting sites in Germany to better understand this highly specialized host–parasite interaction. The shift in host emergence due to stylopization was proven to be especially strong inA. vaga. Around 10% of bees hosted more than 1Stylops, with at maximum 4. A trend inStylops' preference for hosts of their own sex and a sex-specific position of extrusion from the host abdomen was found. Invasion ofAndrenaeggs byStylopsprimary larvae was depicted for the first time. Cephalothoraces of femaleStylopswere smaller in male and pluristylopized hosts, likely due to lower nutrient supply. The genesH3,18Sandcytochrome c oxidase subunit 1were highly conserved, revealing near-absence of local variation withinStylops. Ovaries of hosts with maleStylopscontained poorly developed eggs while those of hosts with femaleStylopswere devoid of visible eggs, which might be due to a higher protein demand of femaleStylops. MaleStylops, which might have a more energy-consuming development, led to a reduction in head width of their hosts. Host masculinization was present in the leaner shape of the metabasitarsus of stylopized females and is interpreted as a by-product of manipulation of the host's endocrine system to shift its emergence. Stylopization intensified tergal hairiness, most strongly in hosts with femaleStylops, near the point of parasite extrusion, hinting towards substance-induced host manipulation.

Published: May 2023

AbstractDuring the pandemic, older adults were perceived as a vulnerable group without considering their various strengths. This study explored the associations between character strengths and resilience, and verified if some of these could predict resilience during the COVID-19 pandemic. A sample of 92 participants (women = 79.1%), ≥ 70 years of age (mean = 75.6 years), completed an online version of the Values in Action Inventory of Strengths – Positively keyed (VIA-IS-P) to assess 24 character strengths (grouped under six virtues) and the Connor and Davidson Resilience Scale. Results showed that 20 of the 24 strengths correlated positively and significantly with resilience. A multiple regression analysis revealed that the virtues of courage and transcendence, as well as attitudes toward aging, uniquely predicted the level of resilience. Interventions should be developed to improve certain strengths (e.g., creativity, zest, hope, humor, and curiosity), while reducing ageism, in order to promote resilience.
Importance in Shifting Circulation Patterns for Dry Season Moisture Sources in the Brazilian Amazon
Authors: Mu Ye , Biggs Trent W. , Jones Charles 
Published: May 2023

AbstractWater is redistributed from evaporation sources to precipitation sinks through atmospheric moisture transport. In the Brazilian Amazon, the spatial and temporal variability of dry season moisture sources for key agricultural regions has not been investigated. This study investigates moisture sources for dry season rainfall in the state of Rondônia in Brazil, especially during drought years. Using a precipitationshed framework, we quantified the variability of moisture contributions to rainfall in the state of Rondônia (Brazilian Amazon) and the influence of synoptic circulation patterns. Ocean evaporation accounts for 58% of mean dry season precipitation while continental recycling contributed 42%. During drought years, although forests maintain or increase evapotranspiration, the moisture contribution of both ocean and forests to dry season rainfall decreases due to the synoptic circulation changes, reducing the moisture transport into Rondônia.

AbstractLonger-term outcomes with the anti-CD38 antibody isatuximab in combination with carfilzomib-dexamethasone (Isa-Kd) were evaluated in the randomized Phase 3 trial IKEMA (NCT03275285), in a prespecified, follow-up analysis of progression-free survival (PFS, primary study endpoint), final complete response (CR) using Hydrashift Isa immunofixation assay, minimal residual disease (MRD) negativity, and safety. Enrolled patients had relapsed/refractory multiple myeloma (1–3 prior treatment lines). Isa 10 mg/kg was administered intravenously weekly in cycle 1 then biweekly. Efficacy analyses were performed in the intent-to-treat population (Isa-Kd: n = 179, Kd: n = 123) and safety evaluated in treated patients (Isa-Kd: n = 177, Kd: n = 122). Consistent with the primary interim analysis, the addition of Isa to Kd prolonged PFS (HR 0.58, 95.4% CI: 0.42–0.79; median PFS 35.7 [95% CI: 25.8–44.0] vs 19.2 [95% CI: 15.8–25.0] months). PFS benefit was observed with Isa-Kd across subgroups, including patients with poor prognosis. The stringent CR/CR rate was 44.1% vs 28.5% (odds-ratio: 2.09, 95% CI: 1.26–3.48), the MRD negativity rate 33.5% vs 15.4% (odds-ratio: 2.78, 95% CI: 1.55–4.99) and the MRD negativity CR rate 26.3% vs 12.2%, with Isa-Kd vs Kd. The safety profile of Isa-Kd was similar to that reported in the prior interim analysis. These findings further support Isa-Kd as a standard-of-care treatment for relapsed multiple myeloma patients.Clinical trial information: ClinicalTrials.gov, NCT03275285.

Environmental context Intensive aquaculture is the main source of fisheries products. Thus, investigating the food safety of these products and the environmental impacts of the farms on mangroves is necessary. A shrimp productive cycle was evaluated with a focus on trace element accumulation in shrimps and effluent. The results revealed secure levels of elements in the final product; however, the effluent produced in farms is an important source of contamination to mangrove environment. Rationale Aquaculture systems have increased in the last years due to the high demand for seafood consumption, this could impact the environment and subject fisheries to accumulation of toxic elements. To understand some parameters of food safety and environmental impact, the present study evaluated the concentration of trace elements (Al, As, Cd, Co, Cr, Cu, Mn, Mo, Pb, Se, V and Zn) throughout the production cycle of shrimp. Methodology About 50 shrimps per cycle were collected in a shrimp farm in Brazil and their trace element contents were determined by inductively coupled plasma–tandem mass spectrometry (ICP-MS/MS) and microwave-induced plasma–optical emission spectroscopy (MIP-OES). Results At their final lifecycle stage, shrimp samples present a content (mg g−1) of elements following the trend: Cu (102 ± 12) > Al (20.06 ± 4.24) > Zn (14.82 ± 2.46) > Mn (6.24 ± 0.94) > As (2.65 ± 0.42) > Se (0.932 ± 0.140) > Co (0.380 ± 0.05) > Mo (0.254 ± 0.03) > V (0.204 ± 0.02). Discussion The content of Cd and Pb are in allowance with Brazil and USA legislation for crustaceans, however, the content of As is 3–4-fold higher than that allowed by guidelines in all stages of the growth of the shrimp. The final effluent of the shrimp’s pond into the mangroves shows a high mass fraction of Zn and Mn that could be a source of contamination. Some correlations between some elements in the shrimp samples were found, such as As–Se, Se–Co and Se–V. This study was a scoping experiment to study the content of trace elements throughout the farming cycle of shrimps, encouraging the researcher to undergo a wide survey to evaluate the environmental impact of aquaculture shrimp farming.

Contact lenses provide excellent vision correction for many people worldwide. However, they can become colonised by microorganisms and this can result in infections and inflammatory responses at the surface of the eye during wear. If not quickly and appropriately treated, the infections can lead to loss of vision and even loss of the eye. The microorganisms, most commonly bacteria, that colonise the lenses can form biofilms on the lenses. For the past 25 years, we have been studying the epidemiology of contact lens-related infection and inflammation, the causative organisms, risk factors for developing the conditions, and new ways of reducing biofilm formation. This article provides an overview of this research.
Populist radical right beyond Europe
Authors: Balta Evren 
Published: May 2023

Abstract
Turkey’s Justice and Development Party (AKP) is one of the longest ruling among contemporary populist radical
right parties (PRR). For nearly two decades, the AKP has shown tremendous success in achieving electoral dominance and political
control. This article argues that AKP’s success lies in its ability to reconfigure the issue salience in Turkish politics by
bringing the secular-conservative cleavage into the center of political competition. However, as this article shows, while the
government’s framing of conservative/religious values was initially populist, as the Party consolidated its power, populism became
secondary to nativism. This nativist turn is characterized by an emphasis on the foreignness of “the elites” and is shaped by
secularization of the public sphere and antiwesternism. Overall, AKP has not presented a fundamental opposition to the
“establishment” but brought together many components of Turkey’s institutional and cultural structure and radicalized patterns
already present in earlier eras.
On unifying randomized methods for inverse problems
Authors: Wittmer Jonathan , Krishnanunni C G , Nguyen Hai V , Bui-Thanh Tan 
Published: May 2023

Abstract
This work unifies the analysis of various randomized methods for solving linear and nonlinear inverse problems with Gaussian priors by framing the problem in a stochastic optimization setting. By doing so, we show that many randomized methods are variants of a sample average approximation (SAA). More importantly, we are able to prove a single theoretical result that guarantees the asymptotic convergence for a variety of randomized methods. Additionally, viewing randomized methods as an SAA enables us to prove, for the first time, a single non-asymptotic error result that holds for randomized methods under consideration. Another important consequence of our unified framework is that it allows us to discover new randomization methods. We present various numerical results for linear, nonlinear, algebraic, and PDE-constrained inverse problems that verify the theoretical convergence results and provide a discussion on the apparently different convergence rates and the behavior for various randomized methods.

Abstract
Motivated by the experimental progress in the study of heavy baryons, we investigate the mass spectra of strange single heavy baryons in the λ-mode, using the relativistic quark model and the infinitesimally shifted Gaussian basis function method. We show that experimental results are well captured using the predicted masses. The root mean square radii and radial probability density distributions of the wave functions are analyzed in detail. Meanwhile, the mass spectra allow us to successfully construct the Regge trajectories in the

plane. We also preliminarily assign quantum numbers to the recently observed baryons, including

Published: May 2023

Abstract
This paper studies the characteristics of the insulation shear belt produced by the fracture of the vents of the gunhead desceptor and the reasons for its formation when the shell is fired. The results show that: During the explosion, the rupture of the degenerator belongs to the ligament fracture, and the insulation shear belt produced at the time of the break plays the role of “prefabricated crack”. The smaller the microstructure and grain of alloy steel, the easier it is to promote the production of insulation shear belt.
The Vibration Response of the Helicopter Coupling with Aircraft Gun
Authors: Liu J , Zhou F M 
Published: May 2023

Abstract
The vibration response characteristics of the helicopter due to the launching load of the aircraft gun has been studied. Based on the finite element method, a fully coupled dynamics analysis model by considering the helicopter and aircraft gun was constructed. The effect of the aircraft gun launching load on the vibration response of the helicopter was analyzed with the different firing angles of the gun. The results show that the front-back and up-down vibration of the airframe is greatly affected by the elevating firing angles, and the left-right vibration displacement is greatly affected by the azimuth firing angle. The front-back and up-down vibration of the helicopter decreases with the increase of the azimuth firing angle, and the left-right vibration displacement increases with the azimuth firing angle. When the elevating firing angles are at the two limit firing angles of +10 degree and -60 degree, the vibration direction at the same position of the airframe is opposite. The results are useful for the control of airframe vibration and the dynamic matching between the airframe and the gun.
Epoxy Value Measurement of Epoxy Resin TDE-85 by Nuclear Magnetic Resonance Spectroscopy and Titration Methods
Authors: Gong W , Liu X , Zhao XG , Lv H , Yao XX 
Published: May 2023

Abstract
In this paper, the epoxy value of epoxy resin TDE-85 was measured by proton nuclear magnetic resonance (1H-NMR) spectroscopy and tetraethylammonium bromide titration. Comparisons of the measurement results and repeatability of the two methods show that the NMR spectroscopy can be used to measure the epoxy value of epoxy resin TDE-85. However, because of the high requirements for sample purity, when testing TDE-85 containing impurities, the measurement repeatability of NMR spectroscopy is worse than that of tetraethylammonium bromide titration.

Abstract
Thermal power servo system is a typical servo system, the controller as the main component, its parameters decide the control performance of the servo system, The traditional Z-N PID parameter setting method is often unable to achieve the best control performance. The author proposes a particle swarm optimization (PSO) algorithm, which uses the integrated performance index time and error absolute value product integral ITAE as the fitness function and applies it to PID control parameter optimization. The model is built in MATLAB/Simulink for analysis and comparision. The results display that the PSO algorithm is characterized by simple principle, few parameters, easy implementation and fast sensitization speed.
Study on Equipment Support Capability Assessment Method Based on Neural Network
Authors: Tianci Zhang , Yongyong Wei 
Published: May 2023

Abstract
The performance of military equipment keeps improving, and troops are equipped with more and more sophisticated weapons and equipment, highlighting the importance of equipment maintenance and support. Without strong equipment support capability, it is impossilbe to cope with the fast-paced and high-intensity modern warfare, and to effectively give play to the role and advantages of equipment systems integration. Therefore, it is of great significance to have a profound study of and improve the equipment support capability assessment method. Based on requirement analysis, we built an equipment support capability assessment indicator system of the Army Digital Medium-sized Synthetic Brigade in cross-domain operations. The weight of the assessment indicator system was determined using the AHP analytic hierarchy process. The equipment support capability assessment model was constructed. With the data obtained from the exercises using real equipment and system-of-systems (SoS) countermeasure simulation tests, we completed the assessment of the equipment support capability of the Synthetic Brigade using neural network algorithms.
