Selection of propulsion characteristics for systematic assessment of future European RLV-options
Authors: Sippel Martin , Wilken Jascha 
Published: September 2024

Abstract
The propulsion system as the key-element of any space transportation concept is systematically investigated supporting a study on potential future European RLV. Different liquid propellant combinations are compared and evaluated. Subsequently, main stage rocket engines are defined for the two cycle options: open gas-generator and closed staged-combustion. Four different propellant combinations are considered all based on liquid oxygen (LOX) as oxidizer and with the fuel options liquid hydrogen (LH2), liquid methane (LCH4), liquid propane (LC3H8) and kerosene (RP1). These combinations result in eight different generic engines with sub-variants using different nozzle expansion ratios in first and upper stage application. Engine characteristics are similar, as far as conceivable, to be well-suited for the system level comparison of pre-defined RLV-launchers. However, characteristics are not necessarily identical as different engine architectures and propellants might make individual choices necessary. Engine performance characteristics are compared with similar existing engines when available. It is shown that closed-cycle staged combustion engines bring significant performance gains, particularly in sea-level operations. On the other hand, hydrocarbon- and open-cycle gas-generator engines offer a better thrust-to-weight-ratio than hydrogen and staged combustion cycle.

AbstractCannabis use among cancer patients for managing treatment-related symptoms is increasing, yet little is known about patterns in patient-provider communication. This study examines demographic differences in cannabis use communication at a National Cancer Institute-designated cancer center. The analysis included cancer patients aged ≥ 18 years who self-reported current cannabis use (past 30 days) and had visited Sylvester Comprehensive Cancer Center within the past 5 years (N = 226). Data were collected via an anonymous electronic survey on REDCap. Responses on patients’ disclosure of cannabis use to cancer doctor/care team and their comfort in discussing cannabis were analyzed. Chi-squared/Fisher’s exact tests and t-tests were applied. Logistic regression estimated the associations between age and stage of cancer treatment with patients’ comfort in discussing cannabis use with cancer doctor (oncologist). The sample was 51.8% male and 39.4% Hispanic (mean age, 45.9 years (SD = 15.1)); 41.1% were aged 20–39 years, 43.8% were undergoing treatment, and 35.4% were in follow-up/had finished treatment. Over half (50.4%) did not disclose cannabis use to their cancer doctor/care team. Non-disclosers were more often younger (20–39 years) than disclosers (52.6% vs. 29.5%, p < 0.01). Most patients (72.5%) felt comfortable discussing cannabis use with their oncologist; however, younger patients (20–39 years) were more often uncomfortable (40.8%). Logistic regression showed newly diagnosed patients had lower odds (aOR, 0.41; 95% CI, 0.12–0.98) of comfort discussing cannabis compared to those in follow-up/finished treatment. Younger patients (20–39 years) also had lower odds (aOR, 0.11; 95% CI, 0.03–0.40) of feeling comfortable discussing cannabis compared to older patients (≥ 60 years). Age and treatment stage significantly impact the cannabis use disclosure and comfort in discussing it with cancer doctor/care team. These findings underscore the importance of considering age-related factors and treatment status when addressing cannabis use discussions within oncology setting.
Spatio-Temporal Hawkes Point Processes: A Review
Authors: Bernabeu Alba , Zhuang Jiancang , Mateu Jorge 
Published: September 2024

AbstractHawkes processes are a particularly interesting class of stochastic point processes that were introduced in the early seventies by Alan Hawkes, notably to model the occurrence of seismic events. They are also called self-exciting point processes, in which the occurrence of an event increases the probability of occurrence of another event. The Hawkes process is characterized by a stochastic intensity, which represents the conditional probability density of the occurrence of an event in the immediate future, given the observations in the past. In this paper, we present some background and all major aspects of Hawkes processes, with a particular focus on simulation methods, and estimation techniques widely used in practical modeling aspects. We aim to provide a rich and self-contained overview of these stochastic processes as a way to have an overall vision of Hawkes processes in only one piece of paper. We also discuss possibilities for future research in the area of self-exciting processes.
Iperparatiroidismo primitivo in gravidanza
Authors: Cipriani Cristiana 
Published: September 2024

SommarioL’iperparatiroidismo primitivo in gravidanza ha una prevalenza inferiore rispetto alla popolazione generale, anche se dati definitivi non sono disponibili, poiché numerosi sono i casi che restano non diagnosticati. Dal punto di vista clinico, esso può decorrere in modo asintomatico, paucisintomatico o essere associato a complicanze materne quali nefrolitiasi, fratture da fragilità, pancreatite, infezioni urinarie, preeclampsia e, raramente, crisi paratireotossica. Tra le complicanze fetali si annoverano ipocalcemia, prematurità, ritardo di crescita intrauterina, basso peso alla nascita, aborto e natimortalità. La terapia chirurgica rappresenta, come nell’iperparatiroidismo primitivo non in gravidanza, l’unica cura della malattia e trova indicazione in particolare nelle forme più gravi e durante il secondo trimestre di gestazione. Nella presente rassegna sono riassunti i dati più recenti circa la presentazione clinica, la diagnosi e le raccomandazioni terapeutiche dell’iperparatiroidismo primitivo in gravidanza.
Metabotropic glutamate receptors—guardians and gatekeepers in neonatal hypoxic-ischemic brain injury
Authors: Mielecki Damian , Bratek-Gerej Ewelina , Salińska Elżbieta 
Published: September 2024

AbstractInjury to the developing central nervous system resulting from perinatal hypoxia–ischemia (HI) is still a clinical challenge. The only approach currently available in clinical practice for severe cases of HI is therapeutic hypothermia, initiated shortly after birth and supported by medications to regulate blood pressure, control epileptic seizures, and dialysis to support kidney function. However, these treatments are not effective enough to significantly improve infant survival or prevent brain damage. The need to create a new effective therapy has focused attention on metabotropic glutamate receptors (mGluR), which control signaling pathways involved in HI-induced neurodegeneration. The complexity of mGluR actions, considering their localization and developmental changes, and the functions of each subtype in HI-evoked brain damage, combined with difficulties in the availability of safe and effective modulators, raises the question whether modulation of mGluRs with subtype-selective ligands can become a new treatment in neonatal HI. Addressing this question, this review presents the available information concerning the role of each of the eight receptor subtypes of the three mGluR groups (group I, II, and III). Data obtained from experiments performed on in vitro and in vivo neonatal HI models show the neuroprotective potential of group I mGluR antagonists, as well as group II and III agonists. The information collected in this work indicates that the neuroprotective effects of manipulating mGluR in experimental HI models, despite the need to create more safe and selective ligands for particular receptors, provide a chance to create new therapies for the sensitive brains of infants at risk.
“It’s the Only World We’ve Got.” Children’s Responses to Chris Jordan’s Images about SDG 14: Life Below Water
Authors: O’Gorman Lyndal 
Published: September 2024

AbstractBroad and complex ideas about sustainability can be communicated through the Arts. Australian curriculum documents support the integration of Arts education with education for sustainability. Responding to artworks as a viewer is a key aspect of Arts education in Australian schools. Chris Jordan is a US artist whose online media galleries communicate ideas about environmental and social justice themes. This paper reports interview data from a larger project exploring children’s responses to Chris Jordan’s artworks. Conversations were held with 28 children aged between 4 and 12 as they navigated Jordan’s website to explore the images they encountered. Data relating to SDG14: Life below water were selected for the specific focus of this paper. Thematic analysis of the data revealed five themes: connections to prior experience and knowledge, links with local contexts and places, emotional engagement with the images, solutions and action-taking and ideas related to post-humanism and the human-nature binary. These findings endorse the power of Arts-based experiences for enhancing education for sustainability in primary schools and early childhood contexts.
Orating Origins: the Formation of Pakistan in Contemporary Urdu Shi’i Khitabat in Karachi
Authors: Jafri Mohammad Nabeel 
Published: September 2024

AbstractUrdu-speaking Shiʿa khatibs (orators) in Karachi regularly speak on the origins of Pakistan, seeking to recuperate Shiʿi contributions to the foundation of the nation-state. In this article, I argue that such claims do not resist, subvert, or undermine statist historical narratives. Instead, the claims mimic, in structure and teleology, the very statist historical narratives that they attempt to challenge. I draw upon twenty months of ethnographic fieldwork in Karachi and demonstrate how thoroughly circumscribed such claims are. I read this minority rhetoric as an attempt to appropriate the majoritarian discourse, rather than as an attempt to challenge the dominant historiography of the origins of Pakistan. I turn to the domain of Shiʿi khitabat (oratory), a ubiquitous and public performance, and identify the important role played by such mass and physical gatherings in the articulation of historical claims. My works emerges from, and contributes back to, scholarship on South Asian Shiʿism, oratory, and the public sphere.

Abstract
The prevalence of food insecurity in Cyprus and the socio-demographic factors that are related to this public health problem are unknown. Data used in this cross-sectional study were collected between 1 June 2022 and 21 May 2023 using a self-reported method. Food insecurity was evaluated using the Greek version of Adult Food Security Survey Module. The data regarding socio-demographic and socio-economic characteristics along with body weight and height measurements were collected through self-administered questionnaire. A representative sample of n=1255 adults, ≥18 years old living in the five different districts of the Republic of Cyprus, was recruited. Prevalence of food insecurity in Cypriot population was 12.6%. Prevalence was higher in females, in older adults, in adults living in Paphos, in individuals who were separated, divorced, or widowed, in retired people, in people living with children, and in people with low income and education. Based on multivariable analysis, income was the strongest socio-demographic factor independently associated with food security (€ 6,500–€ 19,500: AOR: 0.49, 95% CI 0.28, 0.86 and >€ 19,500: AOR: 0.15, 95% CI 0.73, 0.31). Food insecurity is a global problem that need further examination. The association between food insecurity and socio-demographic characteristics needs to be highlighted in order for each country to develop specific public health policies (e.g. financial support to low income people) to decrease food insecurity and improve people’s overall health and quality of life.

Published: September 2024

Abstract
Folate and vitamin B12 (cobalamin) are essential for growth and development. This cross-sectional study aims to describe folate and vitamin B12 status according to infant age and breastfeeding practices in Norwegian infants. Infants aged 0–12 months (n = 125) were recruited through public health clinics. We registered breastfeeding status and measured serum concentrations of folate, cobalamin, total homocysteine (tHcy), and methylmalonic acid (MMA). The associations between infant age, breastfeeding, and biomarker concentrations were estimated in regression models. The mean (SD) age was 24 (16) weeks, and 42% were exclusively breastfed, 38% were partially breastfed, and 21% were weaned. Overall, median (IQR) folate, cobalamin, tHcy, and MMA concentrations were 47 (35–66) nmol/L, 250 (178–368) pmol/L, 6.99 (5.69–9.27) µmol/L, and 0.35 (0.24–0.83) µmol/L, respectively. None of the infants were folate deficient, 15% were vitamin B12 deficient (< 148 pmol/L), and 23% had low vitamin B12 status (148–221 pmol/L). Elevated tHcy (> 6.5 μmol/L) and MMA (> 0.26 μmol/L) were found in 62% and 69% of the infants, respectively. Compared to weaned, exclusively or partially breastfed infants were younger and had 46% higher tHcy concentrations (P < 0.001), in addition to 47% and 39% lower cobalamin concentrations (P < 0.001), respectively. However, the observed biomarker concentrations appeared to be independent of infant age. In conclusion, low vitamin B12 status was prevalent and appeared to be more common in the younger exclusively breastfed compared to older weaned infants. The implications of low vitamin B12 status in infancy are unknown and require further investigation.

Abstract
Rift propagation, rather than basal melt, drives the destabilization and disintegration of the Thwaites Eastern Ice Shelf. Since 2016, rifts have episodically advanced throughout the central ice-shelf area, with rapid propagation events occurring during austral spring. The ice shelf's speed has increased by ~70% during this period, transitioning from a rate of 1.65 m d−1 in 2019 to 2.85 m d−1 by early 2023 in the central area. The increase in longitudinal strain rates near the grounding zone has led to full-thickness rifts and melange-filled gaps since 2020. A recent sea-ice break out has accelerated retreat at the western calving front, effectively separating the ice shelf from what remained of its northwestern pinning point. Meanwhile, a distributed set of phase-sensitive radar measurements indicates that the basal melting rate is generally small, likely due to a widespread robust ocean stratification beneath the ice–ocean interface that suppresses basal melt despite the presence of substantial oceanic heat at depth. These observations in combination with damage modeling show that, while ocean forcing is responsible for triggering the current West Antarctic ice retreat, the Thwaites Eastern Ice Shelf is experiencing dynamic feedbacks over decadal timescales that are driving ice-shelf disintegration, now independent of basal melt.
The Unbearable Uncertainty of Being on the Front Street-level Military in the Mexican War on Drugs
Authors: Pocoroba Alejandro , Atuesta Laura H. , Treviño-Rangel Javier 
Published: September 2024

AbstractSince the so-called war on drugs began in Mexico in 2006, the military has been the leading actor in charge of the government’s public security policy, undertaking tasks that should be carried out by the police. Analyses of this security strategy are based on quantitative methods and have focused on its results: e.g., an increase in the homicide rate or the committing of human rights violations. In contrast, based on in-depth interviews, this article explores the testimony of military personnel to understand what they experience in the field. Contrary to what the existing literature argues, which maintains that the military acts with a logic of war, this article shows that the situation is far more complex: they act in a scenario characterized by improvisation, facing the dilemma between acting and being accused of human rights or not acting and being accused of disobedience.
Race, Inequality, and Political Trust in Latin America
Authors: Granados Castellar , Sánchez Francisco 
Published: September 2024

AbstractDuring the last decades, political distrust has seemingly become a common trend across Latin American democracies, however, differences in the levels of confidence among groups have also been identified. This article considers the potential effects of ethno-racial structures and their interactions with other forms of socioeconomic inequalities on political trust. Building on data from four waves of the Latinobarometer project and contextual measures from different sources, we analyze these relations and find that both socioeconomic and ethno-racial inequalities affect political trust and impact on the formation of different relations with the political system across Latin America. Furthermore, in particular it is found that at the individual-level interactions between inequalities shape political trust differently depending on the particular ethno-racial identification. These findings contribute to the understanding of ethnicity and race and its associations with other structural inequalities in shaping mass political culture.
Agency Entrenchment: Sociological Legitimacy in a Politically Contested Occupation
Authors: Farrell-Bryan Dylan 
Published: September 2024

AbstractThis study investigates how agents in contested occupations justify and legitimize their work. It examines Immigration and Customs Enforcement (ICE) attorneys who prosecute immigrant removal cases on behalf of the federal government, delving into the narrative strategies that attorneys use to attain self-legitimacy within the agency. While existing literature suggests that self-legitimacy stems from either public support or an intrinsic belief in one’s deservingness of power, this study introduces a third pathway to self-legitimacy, agency entrenchment, in which government prosecutors draw on a highly internalized sense of patriotism and a duty to their organizational role, in the face of heightened public protest and changing administrative priorities. Analyzing forty in-depth interviews with ICE attorneys, this study identifies two primary approaches to agency entrenchment. The first is a bureaucratic approach, in which attorneys derive an internalized sense of duty from the existing law. The second is an enforcement approach, in which attorneys derive moral authority from what they see as their protector status. By deploying these narratives of self-legitimacy, ICE prosecutors attempt to resolve perceived conflicts between their legally mandated responsibilities and the ethical and reputational criticisms they encounter. The findings contribute to the broader understanding of the occupational dynamics between political polarization and law enforcement prosecution.

AbstractChanges in the distribution of species due to global climate change have a critically significant impact on the increase in the spread of invasive species. An in-depth study of the distribution patterns of invasive species and the factors influencing them can help to better predict and combat invasive alien species.Rhynchophorus ferrugineusOlivier is an invasive species that primarily harms plants ofTrachycarpusH. Wendl. The pest invades trees in three main ways: by laying eggs and incubating them in the crown of the plant, on roots at the surface and at the base of the trunk or petiole. Most of the plants in the genusTrachycarpusare taller, and the damage is concentrated in the middle and upper parts of the plant, making control more difficult. In this paper, we combine 19 bioclimatic variables based on the MaxEnt model to project the current and future distributions ofR. ferrugineusunder three typical emission scenarios (2.6 W m−2(SSP1-2.6), 4.5 W m−2(SSP2-4.5) and 8.5 W m−2(SSP5-8.5)) in the 2050s and 2090s. Among the 19 bioclimatic variables, five variables were screened out by contribution rates, namely annual mean temperature (BIO 1), precipitation of driest quarter (BIO 17), minimum temperature of coldest month (BIO 6), mean diurnal range (BIO 2) and precipitation of wettest quarter (BIO 16). These five variables are key environmental variables that influence habitat suitability forR. ferrugineusand are representative in reflecting its potential habitat. The results showed thatR. ferrugineusis now widely distributed in the southeastern coastal area of China (high suitability zone), concentrating in the provinces of Hainan, Guangdong, Fujian, Guangxi and Taiwan. In the future, the area of high and low suitability zones will increase and the area of medium suitability zones will decrease. The area of low suitability zone will still be in the largest proportion. This study aims to provide a theoretical reference for the future control ofR. ferrugineusfrom the perspective of geographic distribution.

AbstractConfronting environments with low relative humidity is one of the main challenges faced by insects with expanding distribution ranges.Anastrepha ludens(the Mexican fruit fly) has evolved to cope with the variable conditions encountered during its lifetime, which allows it to colonise a wide range of environments. However, our understanding of the mechanisms underpinning the ability of this species to confront environments with low relative humidity is incomplete. In this sense, omic approaches such as transcriptomics can be helpful for advancing our knowledge on how this species copes with desiccation stress. Considering this, in this study, we performed transcriptomic analyses to compare the molecular responses of laboratory-rearedA. ludensexposed and unexposed to desiccation. Data from the transcriptome analyses indicated that the responses to desiccation are shared by both sexes. We identified the up-regulation of transcripts encoding proteins involved in lipid metabolism and membrane remodelling, as well as proteases and cuticular proteins. Our results provide a framework for understanding the response to desiccation stress in one of the most invasive fruit fly species in the world.
