Xputer : bridging data gaps with NMF, XGBoost, and a streamlined GUI experience

The rapid proliferation of data across diverse fields has accentuated the importance of accurate imputation for missing values. This task is crucial for ensuring data integrity and deriving meaningful insights. In response to this challenge, we present Xputer, a novel imputation tool that adeptly integrates Non-negative Matrix Factorization (NMF) with the predictive strengths of XGBoost. One of Xp

Alterations of the chemical profile of cholesterol in cancer tissue as traced with ToF-SIMS

Cancer has become one of the leading causes of death, with approximately ten million people worldwide dying from cancer each year. In most cases, cancer spreads to remote organs and develops a resistance to therapy. To reduce the deadly impact of cancer, novel targets for markers for early detection are necessary. Given the notable influence of rapid chemical turnover on isotope effects, the heigh

Composition tunable and stable spontaneous emission and lasing in Cd-alloyed perovskite microdisks

All-inorganic Pb-Cd mixed-cation halide perovskites have emerged as semiconductors exhibiting improved optical and optoelectronic properties. We establish a reliable correlation between photoluminescence and Cd content x in bulk CsPb1−xCdxBr3 compositions, propose pathways of photoexcited charge carrier dynamics in them, and show improved stability of lasing in whispering gallery mode microdisks.

Efficient assignment of identities in anonymous populations

We consider the fundamental problem of assigning distinct labels to agents in theprobabilistic model of population protocols. Our protocols operate under the assumptionthat the size n of the population is embedded in the transition function. W.h.p. (withhigh probability), they are silent, i.e., eventually each agent reaches its nal state andremains in it forever, and they are safe, i.e., never cha

Assembling Our Digital Selves

This performance lecture dealt with plan b's ongoing practice of twenty years of collecting personal data, which has been the basis for a number of art works and performances over the years. As artists, educators and researchers, we have deliberately intermingled our art and life, be it through collecting GPS traces of everywhere we go or shouting all our text messages to one another. For us, the

Loss of glymphatic homeostasis in heart failure

Heart failure (HF) is associated with progressive reduction in cerebral blood flow (CBF) and neurodegenerative changes leading to cognitive decline. The glymphatic system is crucial for the brain's waste removal, and its dysfunction is linked to neurodegeneration.In this study, we used a mouse model of HF, induced by myocardial infarction (MI), to investigate the effects of HF with reduced ejectio

Phylogenomic insights into the relationship and the evolutionary history of planthoppers (Insecta: Hemiptera: Fulgoromorpha)

Planthoppers (Hemiptera: Fulgoromorpha) are a species-rich and globally distributed insect clade with high economic, ecological and evolutionary importance. However, the relationships among planthopper lineages and families remain unclear. Previous efforts based on inconsistent morphological traits, a few genes or limited sampling often resulted in conflicting tree topologies. Here, we used genome

Pervasive horizontal transmission of Wolbachia in natural populations of closely related and widespread tropical skipper butterflies

BACKGROUND: The endosymbiotic relationship between Wolbachia bacteria and insects has been of interest for many years due to their diverse types of host reproductive phenotypic manipulation and potential role in the host's evolutionary history and population dynamics. Even though infection rates are high in Lepidoptera and specifically in butterflies, and reproductive manipulation is present in th

School performance gap between non-immigrant and secondgeneration immigrant children in Sweden -time trends and contributing factors

We aimed to investigate the school performance gap and its potential trend from 2010 to 2020 in non-immigrant and second-generation immigrant children in Sweden, whether parental mental disorders and low socioeconomic status contribute to this gap and its trends, and whether the effects of these factors differ by immigration status. We used multiple Swedish population registers, including 829,787

Swedish State Property at the King’s Disposal: The Historical Development of the Legal Arrangements Concerning the Swedish Royal Palaces and the Financing of the Swedish Royal Family

Since the Middle Ages, there have been Crown estates in Sweden that were to be used by the King. In 1809-10, an agreement was reached between King and Parliament about the financing of the expenses of the Royal Family and the Royal Household and of the right of the King and the Royal Family to use and govern the Royal Palaces. This agreement is still in force, although it has been amended as regarSince the Middle Ages, there have been Crown estates in Sweden that were to be used by the King.

Intelligent Monitoring Applications of Landslide Disaster Knowledge Graphs Based on ChatGLM2

Over the years, the field of landslide disaster research has amassed a wealth of data and specialized knowledge. However, these resources originate from a wide array of sources and often feature complex data structures, highlighting a persistent lack of methods to integrate multi-source, heterogeneous data. Traditional landslide monitoring methods typically focus on singular monitoring targets and

Effects of chemical pretreatment on the enzymatic hydrolysis of post-consumer waste viscose

The pretreatment of post-consumer waste viscose before enzymatic hydrolysis was tested and evaluated to develop a tertiary recycling strategy for waste viscose, as no such strategy currently exists. There were differences between hydrolyzability of pre-consumer and post-consumer viscose, as we obtained 100% glucose yield from pre-consumer viscose while only 60-80% could be achieved from post-consu

Patterns of opportunity spaces and agency across regional contexts : Conditions and drivers for change

Non-metropolitan regions are considered more exposed to external shocks than their metropolitan counterparts, while having lower capacities to change. However, there is considerable variation among non-metropolitan regions. We argue that this variation can be captured theoretically by modelling the dynamic interplay between perceived and real opportunity spaces and agency. We empirically analyse r

Autumn Migration of Aquatic Warblers Acrocephalus paludicola in Portugal Revisited

The Aquatic Warbler Acrocephalus paludicola is a globally threatened, long-distance migratory passerine that continues to decline in abundance and range. Studies throughout its annual cycle are needed, including during migration, when information on habitat availability and usage are important for conservation. Here, the autumn occurrence (distribution, abundance, phenology) of Aquatic Warblers in

Outcomes of elective open surgical repair or fenestrated endovascular aneurysm repair for juxtarenal abdominal aortic aneurysms in Sweden

Background: A juxtarenal abdominal aortic aneurysm is defined as a short (less than 4mm) or no-neck aneurysm, which is often treated with open or complex endovascular repair. The evidence to support the best treatment strategy is scarce. The aim of this study was to assess the short- and mid-term outcomes of elective open surgical repair or fenestrated endovascular aneurysm repair for juxtarenal a

Psychosocial Determinants for Self-Reported Health Status in Hemodialysis Patients : A Cohort Analysis of the CONVINCE Randomized Trial

Background: We investigated whether psychosocial determinants self-efficacy and social support are associated with Health-Related Quality of Life in hemodialysis patients enrolled in the CONVINCE trial. Methods: We used baseline data from the cohort of patients involved in the CONVINCE randomized trial of hemodiafiltration versus hemodialysis. Measures included age, gender, relationship status, ch

M2SKD : Multi-to-Single Knowledge Distillation of Real-Time Epileptic Seizure Detection for Low-Power Wearable Systems

Integrating low-power wearable systems into routine health monitoring is an ongoing challenge. Recent advances in the computation capabilities of wearables make it possible to target complex scenarios by exploiting multiple biosignals and using high-performance algorithms, such as Deep Neural Networks (DNNs). However, there is a tradeoff between the algorithms' performance and the low-power requir
