Quality Requirements for Code : On the Untapped Potential in Maintainability Specifications

Quality requirements are critical for successful software engineering, with maintainability being a key internal quality. Despite significant attention in software metrics research, maintainability has attracted surprisingly little focus in the Requirements Engineering (RE) community. This position paper proposes a synergistic approach, combining code-oriented research with RE expertise, to create

Sulfonate and Ammonium-Grafted Poly(isatin triphenyl) Membranes for the Vanadium Redox Flow Battery

As one of the most critical components of the vanadium redox flow battery (VRFB), the ion exchange membrane directly influences the battery efficiency and cycle life. Herein, poly(isatin triphenyl) (PIT) containing a lactam structure and devoid of ether bonds is synthesized from isatin and p-terphenyl under superacid catalysis. To achieve the ion transport and investigate the impact of side chain

The genomic natural history of the aurochs

Now extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1. Here we analysed 38 ancient genomes and found 4 distinct population ancestries in the aurochs—European, Southwest Asian, North Asian and South Asian—each of whicNow extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1.

A Deep-Learning-Based Partial-Volume Correction Method for Quantitative 177Lu SPECT/CT Imaging

With the development of new radiopharmaceutical therapies, quantitative SPECT/CT has progressively emerged as a crucial tool for dosimetry. One major obstacle of SPECT is its poor resolution, which results in blurring of the activity distribution. Especially for small objects, this so-called partial-volume effect limits the accuracy of activity quantification. Numerous methods for partial-volume c

Tjugo år med Århuskonventionen : - Rättsutveckling och konsekvenser

Efter cirka 20 år med Århuskonventionen har tillämpningen av konventionen haft tid att utvecklas. Införlivandet av konventionen i svensk rätt var från början en komplex uppgift då det inte bara handlar om konventionen i sig själv utan också hur den kan integreras med grundlag, miljöbalk och speciallagar. Till denna komplexitet kommer utvecklingen av riktlinjer på myndigheter och praxis i domstolar

On the H2 optimal control of uniformly damped mass-spring networks

In this paper we provide an analytical solution to an H2 optimal control problem, that applies whenever the process corresponds to a uniformly damped network of masses and springs. The solution covers both stable and unstable systems, and illustrates analytically how damping affects the levels of achievable performance. Furthermore, the resulting optimal controllers can be synthesised using passiv

CO Oxidation Mechanism of Silver-Substituted Mo/Cu CO-Dehydrogenase – Analogies and Differences to the Native Enzyme

The aerobic oxidation of carbon monoxide to carbon dioxide is catalysed by the Mo/Cu-containing CO-dehydrogenase enzyme in the soil bacterium Oligotropha carboxidovorans, enabling the organism to grow on the small gas molecule as carbon and energy source. It was shown experimentally that silver can be substituted for copper in the active site of Mo/Cu CODH to yield a functional enzyme. In this stu

Unveiling impulse buying patterns in travel live-streaming through the lens of social cognitive theory

Grounded in the social cognitive theory, the main aim of this study is to explore the impact of telepresence, social presence, and emotional engagement on impulsive buying tendencies within the realm of travel live-streaming (TLS). To examine further, the moderating effect of guidance shopping was included. An online questionnaire was distributed to 332 live-streaming viewers from China, and the c

Comparison of E-Scooter and Bike Users’ Behavior in Mixed Traffic

This study aims to investigate the different behaviors with respect to safety measures related to the interaction of e-scooters and bikes with cars in mixed traffic. E-scooters are relatively new vulnerable road users, and their behavior is still not fully understood. For this purpose, an observational study was carried out at an unsignalized at-grade intersection in the city of Catania, Italy. A

Further investigations on the Effective Width for district heating systems

District Heating is a cornerstone for the decarbonisation of the heating and cooling sector in Europe. Nonetheless, this technology is currently absent in a majority of the continent's urban areas, and hence the need for appropriate methods by which to estimate the cost, as well as underlying cost parameters, to assess the feasibility of developing district heating networks is of general interest.

Understanding effective width for district heating

District heating is one of the technologies that can contribute to the decarbonisation of the European heat sector. Nonetheless, these infrastructures only deliver about a tenth of the heat demands in the continent. Therefore, it is essential to assess the expansion potential of these systems and to identify which areas should be target for further investigations, which calls for easy-to-use and s

District heating potential in the EU-27 : Evaluating the impacts of heat demand reduction and market share growth

This paper presents a novel approach to modeling the gradual reduction in heat demand and the evolving expansion of district heating (DH) grids for assessing the DH potential in EU member states (MS). It introduces new methodological elements for modeling the impact of connection rates below 100% on heat distribution costs in both dense and sparse areas. The projected heat demand in 2050 is derive

Plasma Phosphorylated Tau 217 and Aβ42/40 to Predict Early Brain Aβ Accumulation in People Without Cognitive Impairment

Importance: Phase 3 trials of successful antiamyloid therapies in Alzheimer disease (AD) have demonstrated improved clinical efficacy in people with less severe disease. Plasma biomarkers will be essential for efficient screening of participants in future primary prevention clinical trials testing antiamyloid therapies in cognitively unimpaired (CU) individuals with initially low brain β-amyloid (

Feasibility of district heating in a mild climate : A comparison of warm and cold temperature networks in Bilbao

District heating and cooling systems can aid in decarbonisation and the provision of efficient heating and cooling in Europe. However, whereas these systems have achieved high penetration rates in colder climates of Northern, Central and Eastern Europe, they remain marginal in milder climates of Southern Europe. In terms of network design, district heating and cooling systems can be configured in

The Social Origins of Democracy and Authoritarianism Reconsidered: Prussia and Sweden in Comparison

In a large social science literature, unequal rural class structures (“landlordism”) are associated with authoritarian political outcomes. This paper revisits the debate focusing on the electoral consequences of land inequality in Prussia, the locus classicus of the pernicious effects of landlordism, and Sweden, often perceived as Prussia’s opposite, with a farmer-dominated social structure and stIn a large social science literature, unequal rural class structures (“landlordism”) are as-sociated with authoritarian political outcomes. This paper revisits the debate focusingon the electoral consequences of land inequality in Prussia, the locus classicus of the per-nicious effects of landlordism, and Sweden, often perceived as Prussia’s opposite, with afarmer-dominated social structure and st

Social trust during the pandemic : Longitudinal evidence from three waves of the Swiss household panel study

In this study, I analyse whether and why people’s social trust, the belief that most people can be trusted, changed during the COVID-19 pandemic in Switzerland. My analysis is guided by two different approaches to potential dynamics in social trust, (1) the settled disposition model which advocates for stability within individuals over time, and (2) the active updating model claiming that crisis-i

Determinants of Gaps in Human Behaviour in Fire Research

This short communication presents the findings of the work conducted by the human behaviour in fire permanent working group of the International Association for Fire Safety Science. Its aim is to identify determinants of research gaps in the field of human behaviour in fire. Two workshops were conducted in 2023 in which research gaps were identified and discussed by twenty experts. The workshops l
