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

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

Using predicted shape string to enhance the accuracy of γ-turn prediction

Numerous methods for predicting c-turns in proteins have been developed. However, the results they generally provided are not very good, with a Matthews correlation coefficient (MCC) ≤0.18. Here, an attempt has been made to develop a method to improve the accuracy of γ-turn prediction. First, we employ the geometric mean metric as optimal criterion to evaluate the performance of support vector mac

Improving the performance of β-turn prediction using predicted shape strings and a two-layer support vector machine model

The β-turn is a secondary protein structure type that plays an important role in protein configuration and function. Development of accurate prediction methods to identify β-turns in protein sequences is valuable. Several methods for β-turn prediction have been developed; however, the prediction quality is still a challenge and there is infstantial room for improvement. Innovations of the proposed

Direct decomposition of three-way arrays using a non-negative approximation

Non-negative matrix approximation (NNMA) has been used in diverse scientific fields, but it still has some major limitations. In the present study a novel trilinear decomposition method, termed three-way NNMA (TWNNMA), was developed. The method decomposes three-way arrays directly without unfolding and overcomes the restriction of locking zero elements in the deduced multiplicative update rules by

Metabolomic analysis of normal (C57BL/6J, 129S1/SvImJ) mice by gas chromatography-mass spectrometry : Detection of strain and gender differences

Previous studies have shown that the C57 and 129 strains of mice display marked differences in behavioural performance, neuroanatomy, neurochemistry and synaptic plasticity. However, few metabolomic studies of their biofluids have been performed. As part of a series of metabolic phenotyping, the effects of gender and strain upon serum metabolite composition and variation are examined in this study

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

Age-related and amyloid-beta-independent tau deposition and its downstream effects

Amyloid-β (Aβ) is hypothesized to facilitate the spread of tau pathology beyond the medial temporal lobe. However, there is evidence that, independently of Aβ, age-related tau pathology might be present outside of the medial temporal lobe. We therefore aimed to study age-related Aβ-independent tau deposition outside the medial temporal lobe in two large cohorts and to investigate potential downstr

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

Synthesis and chemical recycling of biobased poly(acetal-ester)s with a non-cyclic acetal unit

There is a high demand to design and develop recyclable biobased polymers using eco-friendly synthetic approaches. In this work, we present the facile synthesis of two dicarboxylate monomers with a central non-cyclic acetal unit (dimethyl 4,4'(methylenebis(oxy))dibenzoate and dimethyl 4,4'-(methylenebis(oxy))bis(3-methoxybenzoate)), using potentially biosourced methyl paraben and methyl vanillate.

Effective communications on invasive alien species : Identifying communication needs of Swedish domestic garden owners

Invasive alien species threaten biodiversity with domestic gardens acting as a major pathway for the introduction of alien species. Even though the Nordic region is not currently a hotspot for biological invasions, the number of invasions in the Nordic area has been predicted to increase due to climate change. Given a time lag between introduction and invasion, many non-invasive horticultural alie

The Centre for the History of Knowledge (LUCK), Episod 32 : What is the history of knowledge?

The host Maria Bach speaks to Evelina Kallträsk, David Larsson Heidenblad, Anna Nilsson Hammar and Johan Östling about the history of knowledge and how its approaches might be useful for historians of economics.In a new episode of the podcast Ceteris Never Paribus, the host Maria Bach speaks to Evelina Kallträsk, David Larsson Heidenblad, Anna Nilsson Hammar and Johan Östling, all members of the Lund Centre for the History of Knowledge (LUCK). They discuss what is the history of knowledge and how its approaches might be useful for historians of economics.

A closed-loop design for scalable high-order consensus

This paper studies the problem of coordinating a group of nth-order integrator systems. As for the well-studied conventional consensus problem, we consider linear and distributed control with only local and relative measurements. We propose a closed-loop dynamic that we call serial consensus and prove it achieves nth order consensus regardless of model order and underlying network graph. This alle

Biomass residues as resources : An expanded life-cycle perspective

Biomass residues have been identified as potentially promising resources for production of bio-based products and fuels with low climate impacts. Unlike primary biomass such as crops, using residual biomass may avoid issues such as competition over land for food and feed production. To assess the climate impacts of products made from residual biomass, a life cycle assessment (LCA) may be used, butBiomass residues have been identified as potentially promising resources for production of bio-based products and fuels with low climate impacts.

What are the views of the Italian secondary school students about the future of education, and what conception of Europe are they developing? This report presents the results of the survey “Futures for education and europeanity”, which in 2021, in the midst of the pandemic, collected the opinions of the Italian Provincial Student Councils, representative bodies spread throughout the country, about
