Abstract
Purpose
Lake Victoria has been increasingly silting over the past decades, impacting water quality and loss of biodiversity. Sediment control strategies require information on the relative and absolute contributions of sediment from different sources. However, to date, there is no continuous monitoring of sediment flux or water quality in any of the tributaries, prohibiting an assessment of the scale of the problem. The aim of this study was to trace the dominant sources of riverine sediment using geochemical fingerprinting, thereby generating a knowledge base for improving land management and reducing sediment yields in Simiyu River catchment, one of the main contributing rivers to Lake Victoria.

Materials and methods
Geochemical tracer concentrations were analyzed in transported sediment from the main river and two tributaries (riverbed sediments) and from soils in five dominant land use types (agricultural land, bush land, forest land, channel banks, and main river banks). Dominant sources to the Simiyu main river sediment were attributed using the Bayesian MixSIAR model.

Results and discussion
The mixing model outputs showed that the Simiyu tributary was the dominant source of sediment to the Simiyu main river with 63.2%, while the Duma tributary accounted for 36.8%. Cultivated land was shown to be the main land use source of riverine sediment, accounting for 80.0% and 86.4% in Simiyu and Duma sub-tributaries, respectively, followed by channel banks with 9.0% in both sub-tributaries. Direct unmixing of the Simiyu main river sediment to the land use sources yielded 64.7% contribution of cultivated land and 26.5% of channel banks.

Conclusion
The demonstrated application of sediment source tracing provides an important pathway for quantifying the dominant sources of sediment in the rivers flowing towards Lake Victoria. Eroded soil from agricultural areas is the biggest contributor to transported sediment in the Simiyu River. This information is vital for the design of catchment wide management plans that should focus on reducing soil erosion and sediment delivery from farming areas to the river networks, ultimately supporting both food security and water quality in the Lake Victoria Basin.
Diagnostic, Prognostic, and Predictive Role of Ki67 Proliferative Index in Neuroendocrine and Endocrine Neoplasms: Past, Present, and Future
Authors: La Rosa Stefano 
Published: February 2023

AbstractThe introduction of Ki67 immunohistochemistry in the work-up of neuroendocrine neoplasms (NENs) has opened a new approach for their diagnosis and prognostic evaluation. Since the first demonstration of the prognostic role of Ki67 proliferative index in pancreatic NENs in 1996, several studies have been performed to explore its prognostic, diagnostic, and predictive role in other neuroendocrine and endocrine neoplasms. A large amount of information is now available and published results globally indicate that Ki67 proliferative index is useful to this scope, although some differences exist in relation to tumor site and type. In gut and pancreatic NENs, the Ki67 proliferative index has a well-documented and accepted diagnostic and prognostic role and its evaluation is mandatory in their diagnostic work-up. In the lung, the Ki67 index is recommended for the diagnosis of NENs on biopsy specimens, but its diagnostic role in surgical specimens still remains to be officially accepted, although its prognostic role is now well documented. In other organs, such as the pituitary, parathyroid, thyroid (follicular cell-derived neoplasms), and adrenal medulla, the Ki67 index does not play a diagnostic role and its prognostic value still remains a controversial issue. In medullary thyroid carcinoma, the Ki67 labelling index is used to define the tumor grade together with other morphological parameters, while in the adrenal cortical carcinoma, it is useful to select patients to treated with mitotane therapy. In the present review, the most important information on the diagnostic, prognostic, and predictive role of Ki67 proliferative index is presented discussing the current knowledge. In addition, technical issues related to the evaluation of Ki67 proliferative index and the future perspectives of the application of Ki67 immunostaining in endocrine and neuroendocrine neoplasms is discussed.
The behavior of micropiled raft foundations subjected to combined vertical and lateral loading: numerical study

Published: February 2023

AbstractThe micropiled raft offers a foundation system that combines the advantages of the conventional piled raft and the efficient installation of micropiles. In this paper, a comprehensive numerical analysis was conducted on the behavior of micropiled rafts under combined vertical and lateral loading using finite element modeling. A numerical model calibrated against full-scale axial and lateral field tests is used to conduct the analysis. The soil profile was soft clay soil underlain by a layer of dense sand. Numerous cases were analyzed to assess the lateral performance of micropiled rafts while considering several factors that may affect the performance, such as micropiles spacing, raft thickness, the magnitude of vertical loading, micropiles length, and their arrangement. The difference between the lateral performance of a primary micropiled raft and that of an existing raft enhanced by underpinning micropiles was also investigated. The lateral load capacity of the micropiled raft, the bending moment, and the shear force along the micropiles depth were estimated. Moreover, the load-sharing ratio between the micropiles and the raft was assessed. Based on the parametric study results, significant guidelines for choosing suitable micropiled raft configurations for initial design purposes were provided.

Published: February 2023

Abstract
Purpose
The Young Positive Schema Questionnaire (YPSQ) measures early adaptive schemas (EAS) which could be used to develop positive psychology and schema-based interventions to benefit the treatment of eating disorders (EDs).

Methods
The present study investigated the factor structure of the YPSQ in a sample of 826 participants (18–73 years; n = 753 women) with ED symptomatology (e.g., restricting, binging, and purging). The sample was randomly split into two groups for exploratory and confirmatory factor analyses. Full sample analysis using Pearson correlations was conducted to explore convergent validity of the new YSPQ factor structure with ED symptomatology, emotional regulation, and cognitive flexibility.

Results
A nine-factor model was found, demonstrating good fit indices and internal consistency (α = 0.77–0.92). The YPSQ showed an inverse relationship to ED symptomatology and emotional suppression, and a positive relationship with cognitive flexibility and emotion reappraisal.

Conclusion
Further research is needed to explore the clinical benefits of the YPSQ to identify EAS deficits in individuals with EDs to improve treatment outcomes.

Published: February 2023

Abstract
Purpose
Screen time has been previously linked to body dissatisfaction and eating disorder behaviors. However, less is known about whether use of common forms of screen technology is associated with symptoms of muscle dysmorphia (MD), which was the aim of this study.

Methods
Data from the Canadian Study of Adolescent Health Behaviors (N = 2538) were analyzed. Associations between hours of use of six contemporary forms of recreational screen time, as well as total screen time, and symptoms of MD were determined using multiple linear regression models, stratified by gender, and adjusting for potential confounders.

Results
Among both men and women, greater total screen time and texting were associated with greater symptoms of MD; however, differences emerged across the screen time modalities by gender. Among women, video chatting was most strongly associated with symptoms of MD, while social media use was most strongly associated with symptoms of MD among men.

Conclusion
Findings add to the growing literature documenting the potentially harmful correlates of screen time by including MD symptomatology. Findings have important implications for health care, public health, and policymaking professionals.

Published: February 2023

Abstract
Hydrogen-bonded organic frameworks (HOFs) have emerged as a new class of crystalline porous materials, and their application in membrane technology needs to be explored. Herein, for the first time, we demonstrated the utilization of HOF-based mixed-matrix membrane for CO2 separation. HOF-21, a unique metallo-hydrogen-bonded organic framework material, was designed and processed into nanofillers via amine modulator, uniformly dispersing with Pebax polymer. Featured with the mix-bonded framework, HOF-21 possessed moderate pore size of 0.35 nm and displayed excellent stability under humid feed gas. The chemical functions of multiple binding sites and continuous hydrogen-bonded network jointly facilitated the mass transport of CO2. The resulting HOF-21 mixed-matrix membrane exhibited a permeability above 750 Barrer, a selectivity of ~ 40 for CO2/CH4 and ~ 60 for CO2/N2, surpassing the 2008 Robeson upper bound. This work enlarges the family of mixed-matrix membranes and lays the foundation for HOF membrane development.
Ramsey numbers of cycles versus general graphs
Authors: Haslegrave John , Hyde Joseph , Kim Jaehoon , Liu Hong 
Published: February 2023

Abstract
The Ramsey number

$R(F,H)$

is the minimum number N such that any N-vertex graph either contains a copy of F or its complement contains H. Burr in 1981 proved a pleasingly general result that, for any graph H, provided n is sufficiently large, a natural lower bound construction gives the correct Ramsey number involving cycles:

$R(C_n,H)=(n-1)(\chi (H)-1)+\sigma (H)$

, where

$\sigma (H)$

is the minimum possible size of a colour class in a

$\chi (H)$

-colouring of H. Allen, Brightwell and Skokan conjectured that the same should be true already when

$n\geq \lvert H\rvert \chi (H)$

.
We improve this 40-year-old result of Burr by giving quantitative bounds of the form

$n\geq C\lvert H\rvert \log ^4\chi (H)$

, which is optimal up to the logarithmic factor. In particular, this proves a strengthening of the Allen–Brightwell–Skokan conjecture for all graphs H with large chromatic number.
“Two Courts” for One Constitution: Fragmentation of Constitutional Review in the Law of the Kosovo Specialist Chambers in The Hague
Authors: Hasani Enver , Korenica Fisnik 
Published: February 2023

AbstractThe Kosovo Specialist Chambers embody a remarkable project involving elements of the domestic law of the Republic of Kosovo, the EU’s external relations law, and international criminal law. The Chambers’ hybrid nature is not only unique, but also atypical in regards to its influence in Kosovo’s constitutional order. The Specialist Constitutional Chamber is one of the instances of the Kosovo Specialist Chambers sitting in the Hague. The Specialist Constitutional Chamber resembles Kosovo’s Constitutional Court on a specific, though exclusive, area of law—the law surrounding the court in general. The two courts not only exercise the same generic function—on the basis of exclusive material criteria—but also possibly parallel and compete with each other. The relationship between the “two courts” is at best explained with the term “fragmentation of constitutional jurisdiction.” While the two courts are forced to endure under the same normative roof—the Constitution—they inherently exercise often conflicting functions and protect irreconcilable ideological perspectives. The article examines the interaction between the two courts primarily in a normative and jurisdictional perspective. It also presents recent tendencies of both courts to divert in divergent pathways. The article concludes that while the two courts present an unobserved case in comparative constitutional law, they also reveal an interesting and unconventional constitutional controversy appearing in the context of a sovereign country’s relationship with international law obligations.

ResumenSe analizan los microrrestos biosilíceos recuperados en el sitio Fuerte Sancti Spiritus, primer asentamiento español que se estableció en la cuenca del Río de la Plata en el período de la colonización y conquista europea en América. Está emplazado en Puerto Gaboto, provincia de Santa Fe, Argentina, y consiste en una ocupación breve que se produjo entre mayo de 1527 y septiembre de 1529. La excavación se realizó de acuerdo con la metodología open area, por lo cual el muestreo estuvo distribuido en diferentes rasgos localizados en la planta del emplazamiento. Se analizaron 20 muestras según dos variables: tipo de rasgo y cronología, lo que permitió establecer que se cultivaba maíz, junto con trigo y probablemente cebada, introducidos, concordante con las fuentes etnohistóricas. El análisis permitió, también, estimar el contenido de los rasgos de acuerdo con el sedimento muestreado, posibilitando la caracterización de zonas de descarte, rellenos, niveles de uso y sedimento acumulado con posterioridad al abandono del asentamiento.
Scaffold: A Causal Concept for Evolutionary Explanations
Authors: Neto Celso , Meynell Letitia 
Published: February 2023

AbstractThe concept of scaffold is widespread in science and increasingly common in evolutionary biology. While this concept figures in causal explanations, it is not clear what scaffolds are and what role they play in those explanations. Here we present evolutionary scaffolding explanation as a distinct type of explanatory strategy, distinguishing it from other types of evolutionary explanation. By doing so, we clarify the meaning of “scaffold” as a causal concept and its potential contribution to accounts of evolutionary novelty and major transitions.
Scurvy and the Ontology of Natural Kinds
Authors: Magnus P.D. 
Published: February 2023

AbstractSome philosophers understand natural kinds to be the categories which are constraints on enquiry. In order to elaborate the metaphysics appropriate to such an account, I consider the complicated history of scurvy, citrus, and vitamin C. It may be tempting to understand these categories in a shallow way (as mere property clusters) or in a deep way (as fundamental properties). Neither approach is adequate, and the case instead calls for middle-range ontology: starting from categories which we identify in the world and elaborating their structure, but not pretending to jump ahead to a complete story about fundamental being.
Participatory Modeling in Sustainability Science: The Road to Value-Neutrality
Authors: MacLeod Miles , Nagatsu Michiru 
Published: February 2023

AbstractParticipatory modeling in sustainability science allows scientists to take stakeholders’ interests, knowledge, and values into account when designing a model-based solution to a sustainability problem, by incorporating stakeholders in the model-building process. This improves the chance of generating socially robust knowledge and consensus on solutions. Part of what helps in this regard is that scientists, through involving stakeholders, limit their own values from influencing the outcome, thus achieving some level of value-neutrality. We argue that while it might achieve this to some extent, it comes at a cost to the reliability of the outcomes, which is ethically problematic.
Functionalism, Reductionism, and Levels of Reality
Authors: Lorenzetti Lorenzo 
Published: February 2023

AbstractI consider a problem for functional reductionism based on the following tension. Say that b is functionally reduced to a. On one hand, a and b turn out to be identical, and identity is a symmetric relation. On the other hand, functional reductionism implies that a and b are asymmetrically related: if b is functionally reduced to a, then a is not functionally reduced to b. Thus we ask, how can a and b be asymmetrically related if they are the same thing? I propose a solution to this tension by distinguishing between ontological levels and levels of description.

Published: February 2023

AbstractThe American Society of Parenteral and Enteral Nutrition recommends nutritional risk (NR) screening in critically ill patients with Nutritional Risk Screening – 2002 (NRS-2002) ≥ 3 as NR and ≥ 5 as high NR. The present study evaluated the predictive validity of different NRS-2002 cut-off points in intensive care unit (ICU). A prospective cohort study was conducted with adult patients who were screened using the NRS-2002. Hospital and ICU length of stay (LOS), hospital and ICU mortality, and ICU readmission were evaluated as outcomes. Logistic and Cox regression analyses were performed to evaluate the prognostic value of NRS-2002, and a receiver operating characteristic curve was constructed to determine the best cut-off point for NRS-2002. 374 patients (61·9 ± 14·3 years, 51·1 % males) were included in the study. Of these, 13·1 % were classified as without NR, 48·9 % and 38·0 % were classified as NR and high NR, respectively. An NRS-2002 score of ≥ 5 was associated with prolonged hospital LOS. The best cut-off point for NRS-2002 was a score ≥ 4, which was associated with prolonged hospital LOS (OR = 2·13; 95 % CI: 1·39, 3·28), ICU readmission (OR = 2·44; 95 % CI: 1·14, 5·22), ICU (HR = 2·91; 95 % CI: 1·47, 5·78) and hospital mortality (HR = 2·01; 95 % CI: 1·24, 3·25), but not with ICU prolonged LOS (P = 0·688). NRS-2002 ≥ 4 presented the most satisfactory predictive validity and should be considered in the ICU setting. Future studies should confirm the cut-off point and its validity in predicting nutrition therapy interaction with outcomes.

AbstractChemical defoliants are widely used in cotton (GossypiumL.) to accelerate leaf abscission and boll maturation, as well as, to facilitate mechanical harvesting. The current study was conducted to determine the interactive effect of cotton cultivars and spraying time of defoliant on defoliation, boll opening, fibre yield and quality. An experiment was performed with four cultivars and three defoliant spraying time during 2019 and 2020 in split plot design with three replications. At harvest, the defoliation and boll opening rate of all treatments after spraying defoliant was 94.6 and 85.4%, while the blank control (water) was 73.9 and 79.1%, respectively. After spraying defoliant, the effects of defoliation rate, boll opening rate, fibre yield and quality were different among cultivars, indicating that different cultivars had different responses to defoliant. Among them, L7619 was the most sensitive to defoliant, with the average defoliation rate of 95.6% and a seed cotton yield reduction of 882.9 kg/ha. Among the different time of applications, late spraying (17 September, B3) of defoliant recorded the highest defoliation rate (97.3%), boll opening rate (89.8%), seed cotton yield (3991 kg/ha) and steadily increased the fibre strength by 0.59 cN/tex compared with the control. Late spraying of defoliant had little or even no adverse effect on the remaining fibre quality traits (length, uniformity, micronaire and elongation). In general, these results suggested that the appropriate time for spraying defoliant can be determined based on the sensitivity of the cotton cultivar, the weather conditions at the field and the harvest time.

Published: February 2023

AbstractHealth-conscious consumers are increasingly paying attention to healthy diets and focusing on natural bioactive compounds in foods and their effects on mental health. This opens new opportunities for the study of artisanal cheeses as biofunctional foods. In the work described in this Research Communication, the gamma-aminobutyric acid (GABA) content of seven different Portuguese cheeses produced from unpasteurized cow, sheep, and goat milk and granted with protected designation of origin (PDO) status was analysed. The PDO cheeses made from cow milk analysed in this study were São Jorge (3, 4, 7, 12 and 24 months of maturation) and Pico cheeses. PDO cheeses made from sheep milk were Serra da Estrela, Serpa, Nisa and Azeitão. Cheeses made from sheep and goat milk included Beira Baixa yellow cheese. The GABA content in the Azorean PDO cheeses (made from cow milk) ranged from 1.23 to 2.64 g/kg of cheese. Higher variations in GABA content were observed in cheeses made from sheep and goat milk (0.73–2.31 g/kg). This study provides information on the GABA content in different Portuguese PDO cheeses and shows that hard or semi-hard ripened cheeses are a suitable matrix for GABA production by lactic acid bacteria.
Modified transseptal approach in endoscopic transsphenoidal pituitary surgery
Authors: Gan R , Stokes S , Bahl A , Jose J 
Published: February 2023

AbstractObjectiveTranssphenoidal pituitary surgery is commonly performed via a direct transostial approach with a posterior septectomy. However, a technique via an endoscopic transseptal route has been described that avoids a posterior septectomy, but it comes with its own disadvantages.MethodsThis paper describes a modification, and discusses its pros and cons.ResultsThe initial incision in the mucosa is placed level with the anterior middle turbinate. The mucoperichondrial flap is raised ipsilaterally until the sphenoid sinus ostium. An incision is made at the osseocartilaginous junction, and the contralateral mucoperichondrial flap is raised. The bony septum and posterior aspect of this flap is excised. The size and position of this window can be adapted. At the end of the operation, the lateralised intact mucoperichondrial flap is moved back to the midline.ConclusionExcision or deflection of the cartilaginous septum is not required. It maintains an intact septal mucosa on one side and avoids a septal perforation.
