Massive multiple-input multiple-output (MIMO) is one of the key candidates for the upcoming 5G wireless generation. It offers a multitude of advantages over traditional techniques, such as reduced latency, reduced interference among user equipments (UEs) and increased spectrum and energy efficiencies. However, to verify the theoretically promised gains in real-life, prototype systems are inevitabl
The Learning with Errors problem (LWE) has become a central topic in recent cryptographic research. In this paper, we present a new solving algorithm combining important ideas from previous work on improving the Blum-Kalai-Wasserman (BKW) algorithm and ideas from sieving in lattices. The new algorithm is analyzed and demonstrates an improved asymptotic performance. For the Regev parameters $q=n^2$
Running regression tests for Modelica models usually takes a long time. This paper presents a safe regression test selection technique for Modelica based on static analysis. The technique tracks dependencies between classes to compute which tests that need to be run given a change. The dependency rules have been verified using mutation testing. The technique has been evaluated on the Modelica Stan
A search for new resonances decaying into jets containing b-hadrons in pp collisions with the ATLAS detector at the LHC is presented in the dijet mass range from 0.57 to 7 TeV. The data set corresponds to an integrated luminosity of up to 36.1 fb-1 collected in 2015 and 2016 at s=13 TeV. No evidence of a significant excess of events above the smooth background shape is found. Upper cross-section l
Just like current software systems, models are characterised by increasing complexity and rate of change. Yet, these models only become useful if they can be continuously evaluated and validated. To achieve sufficiently low response times for large models, incremental analysis is required. Reference Attribute Grammars (RAGs) offer mechanisms to perform an incremental analysis efficiently using dyn
The systematic review of universities and social innovations was carried out by placing universities within the broad framework of social innovation. Focus on social innovation as a response to development and societal problems, the review adopted a three-prong approach by analysing the drivers, process and impact of social innovations in the three core missions of universities: teaching, research
BACKGROUND: Alzheimer's disease pathology can be accurately identified with blood biomarkers (core 1 biomarkers), including plasma p-tau217 tests. Biomarkers that change longitudinally after diagnosis (core 2 biomarkers) can increase confidence that Alzheimer's disease pathology is contributing to cognitive symptoms. Plasma eMTBR-tau243 reflects tau tangle pathology and is a promising core 2 bioma
Age of Information (AoI) is a widely used metric to quantify the freshness of updates in communication systems. Existing AoI analyses implicitly assume a shared or synchronized notion of time between transmitter and receiver, thereby neglecting distortions arising from relative motion and gravitational effects. In this paper, we investigate the impact of relativistic time dilation on information f
I dagens välfärdstjänster har synen på användaren i allt högre grad förskjutits från en passiv mottagare till en aktiv deltagare i värdeskapande. Denna förskjutning återspeglas i policyreformer, organisatoriska strategier och akademisk diskurs, vilka alla i ökande grad betonar användarorientering. Inom det teoretiska ramverket Public Service Logic (PSL) framställs användarorientering som ett sätt In today’s welfare services, how the user is viewed has increasingly been shifting away from a passive recipient towards an active participant in value creation. This shift is reflected in policy reforms, organisational strategies, and academic discourse, with all of these placing a growing emphasis on user orientation. Within the theoretical framework of Public Service Logic (PSL), user orientati
We provide a detailed characterization of the planetary system orbiting HD 85426 (TOI-1774). This bright G-type star (: 0.99;: 1.13; age: 7.4 Gyr; V mag: 8.25) hosts a transiting sub-Neptune, HD 85426 b, with an orbital period of 16.71 d and a blackbody equilibrium temperature of K. By jointly analysing HARPS-N RVs, TESS, and CHEOPS photometric data and using two different stellar activity mitigat
This paper examines how extreme weather events affect the mobility of low-income urban residents in Ghana. Bringing together scholarship on extreme weather and mobilities, it explores the differential impact of flooding on their everyday lives as they navigate the cities of Accra and Tamale. A range of qualitative methods were drawn on, including semi-structured interviews, focus group discussions
In recognition of outstanding articles published in the Journal of Comparative Physiology A, Editors’ and Readers’ Choice Awards are conferred annually to the top papers in the categories Original Research Paper and Review/Review-History Article. The recipients of the 2026 Editors’ Choice Awards were selected based on votes cast by the Editorial Board on articles published in 2025. In the category
We study a class of dynamical multi-commodity flows in transportation networks. These are modeled as dynamical systems describing the evolution of the densities of a number of different commodities across the cells of a transportation network. Each cell is characterized by commodity-specific increasing demand functions returning the maximum outflow of each commodity from the cell as a function of
Traumatic brain injury (TBI) is commonly associated with white matter injury, leading to persistent symptoms and long-term disability. While advanced age is linked to worse outcome post-TBI, the influence of sex remains highly controversial. The present study aimed to identify age- and sex-dependent differences in white matter pathology during the chronic phase of TBI using the central (midline) f
Problempresentation: Vietnam drabbas av i genomsnitt 5-6 tyfoner varje år, och dessa kan orsaka stor förödelse och många dödsfall när de passerar in över land. När en tyfon passerar medför det högt vattenstånd, höga vågor, starka vindar och kraftiga regnfall. Om högt vattenstånd sammanfaller med höga vågor orsakar det översköljning samt erosion av strandvallar och sanddyner längs kustlinjen. Detta
Problemformulering: I och med avregleringen av elmarknaden konkurrensutsattes elleverantörernas verksamhet. Priserna pressades och elleverantörerna började ägna sig åt kringtjänster för att anpassa sig till marknaden. För att förbli kundernas val samt för att locka till sig nya kunder tvingas företagen att bevisa sin lämplighet som leverantör, vilket är svårt på en mogen marknad med en homogen kär
Radio links in wireless mesh networks (WMN) can select one of several modulation and coding schemes (MCS). A MCS assignment influences links data rates and their mutual interference, and therefore should be optimized. We consider joint optimization of link rate assignment and transmission scheduling in order to maximize the minimal flow in a WMN. One of the main difficulties stems from the require
Abstract in UndeterminedThe properties of the single-link multiple-input-multiple- output (MIMO) propagation channels have been analyzed in many studies based on extensive propagation measurements. In this letter, we extend the measurement-based analysis to dual-link MIMO propagation channels. Here, we examine interlink correlation by evaluating the correlation of eigenvectors obtained from multip
