Applying Mondrian Cross-Conformal Prediction to Estimate Prediction Confidence on Large Imbalanced Bioactivity Data Sets

Conformal prediction has been proposed as a more rigorous way to define prediction confidence compared to other application domain concepts that have earlier been used for QSAR modeling. One main advantage of such a method is that it provides a prediction region potentially with multiple predicted labels, which contrasts to the single valued (regression) or single label (classification) output pre

Application of Bioactivity Profile-Based Fingerprints for Building Machine Learning Models

The volume of high throughput screening data has considerably increased since the beginning of the automated biochemical and cell-based assays era. This information-rich data source provides tremendous repurposing opportunities for data mining. It was recently shown that biochemical or cell-based assay results can be compiled into so-called high-throughput fingerprints (HTSFPs) as a new type of de

A novel structural position-specific scoring matrix for the prediction of protein secondary structures

Motivation: The precise prediction of protein secondary structure is of key importance for the prediction of 3D structure and biological function. Although the development of many excellent methods over the last few decades has allowed the achievement of prediction accuracies of up to 80%, progress seems to have reached a bottleneck, and further improvements in accuracy have proven difficult. Resu

Identification of the subcellular localization of mycobacterial proteins using localization motifs

Mycobacterium, the most common disease-causing genus, infects billions of people and is notoriously difficult to treat. Understanding the subcellular localization of mycobacterial proteins can provide essential clues for protein function and drug discovery. In this article, we present a novel approach that focuses on local sequence information to identify localization motifs that are generated by

Degradation of multi-layer CVD-coated cemented carbide in finish milling compacted graphite iron

Stricter regulations on emissions and higher demands on engine performance drive automotive industries to replace conventional gray cast iron with compacted graphite iron (CGI). CGI has a higher wear resistance, strength, elastic modulus, and almost double fatigue strength as to gray cast iron, yet the same positive properties make CGI more difficult to machine. This study focuses on finish millin

We looked at 1,154 climate science results and found no evidence of ‘publication bias’

It is rare to encounter a scientific fact that stirs widespread debate and distrust quite like the matter of climate change.Despite consensus among climate specialists about a theory that is supported by a mountain of facts from the physical, natural, and cultural sciences, the debate continues to be perpetrated by politicians, industrialists, academics, and armchair scientists.When governments re

Determinants of cognitive and brain resilience to tau pathology: a longitudinal analysis

Mechanisms of resilience against tau pathology in individuals across the Alzheimer’s disease spectrum are insufficiently understood. Longitudinal data are necessary to reveal which factors relate to preserved cognition (i.e. cognitive resilience) and brain structure (i.e. brain resilience) despite abundant tau pathology, and to clarify whether these associations are cross-sectional or longitudinal

Arbetslivsforskning vid Lunds universitet : En inventering av arbetslivsforskningens omfattning, hemvist och förutsättningar

Vi lever i en tid då arbetslivet – både i Sverige och globalt – genomgår storaförändringar och står inför stora utmaningar. Arbetslivsforskning har därför enstor samhällelig relevans. Men hur står det egentligen till med arbetslivsforskningen vid Lunds universitet? Hur många arbetslivsforskare finns det och var någonstans håller de hus? Och hur ser de på förutsättningarna för att bedriva arbetsliv

Parents' recalled experiences of the child centred health dialogue in children with overweight: a qualitative study

Background: Because overweight and obesity are still increasing and prevention of childhood obesity is more likely to be effective when initiated in preschool children, the Child Health Service in the south of Sweden developed a structured child-centred health dialogue model targeting all 4-year-old children and their families. The aim of this study was to describe parents' recalled experiences of

The Simple One-step stool processing method for detection of Pulmonary tuberculosis : A study protocol to assess the robustness, stool storage conditions and sampling strategy for global implementation and scale-up

BACKGROUND: The Xpert MTB/RIF Ultra (Xpert-Ultra) assay provides timely results with good sensitivity and acceptable specificity with stool specimens in children for bacteriological confirmation of tuberculosis (TB). This study aims to optimize the Simple One-Step (SOS) stool processing method for testing stool specimens using the Xpert-Ultra in children and adults in selected health facilities in

Kvantitativa metoder i socialpolitiska studier : - en introduktion med frågor och övningsexempel i fyra delar

I rapporten underlaget presenteras grundläggande utgångspunkter och verktyg för studier som baseras på kvantitativa metoder. Avsikten är i första hand att komplettera kurslitteraturen på området och visa hur kvantitativa analysmetoder kan nyttjas i samband med socialpolitiskt inriktade studier. Syftet är också att öka kunskapen och förmågan att bearbeta och värdera statistik om sociala förhållande

Poor adult tuberculosis treatment outcome and associated factors in Gibe Woreda, Southern Ethiopia : An institution-based cross-sectional study

Tuberculosis (TB) remains a major medical and public health problem throughout the world, especially in developing countries including Ethiopia. Its control program is currently being challenged by the spread of drug-resistant TB, which is the result of poor treatment outcomes. Hence, this study assessed poor adult TB treatment outcomes and associated factors in Gibe Woreda, Southern Ethiopia. An

Associations in Perceived Health and Persistent Breathlessness: A Cross-Sectional Study

Background: Persistent breathlessness is debilitating and increases in prevalence with advanced age and at end of life. This study aimed to evaluate any relationship between self-reported global impressions of change (GIC) in perceived health and breathlessness in older men.Design: Cross-sectional study of 73-year-old Swedish men in the VAScular and Chronic Obstructive Lung disease study. A postal

Anatomical and histopathological approaches to asthma phenotyping

Asthma is typically characterized by variable respiratory symptoms and airflow limitation. Along with the pathophysiology and symptoms are immunological and inflammatory processes. The last decades research has revealed that the immunology of asthma is highly heterogeneous. This has clinical consequences and identification of immunological phenotypes is currently used to guide biological treatment

Striving towards normality in an unpredictable situation. A qualitative interview study of how persons newly diagnosed with incurable oesophageal and gastric cancer manage everyday life

Purpose: Getting an incurable oesophageal or gastric cancer diagnosis is a major stressful life event associated with severe physical, psychosocial and existential challenges. To provide timely and efficient support, based on patients' experiences, the aim of the study was to explore how patients newly diagnosed with incurable oesophageal and gastric cancer manage everyday life. Method: Semi-struc

Open Mouth Operations. Monetary Policy by Threats and Arguments. The Monthly Meetings Between the Riksbank and the Commercial Banks, 1956-73

After World War II and prior to the financial deregulation of the 1980s, monetary policy in Sweden as well as in other western European countries rested chiefly on a system of far- reaching non-market-oriented controls of credit flows and interest rates. How was monetary policy conducted in such an environment of financial repression, where the central bank was unable to rely on traditional moneta
