Controlling the water level in irrigation channels is important for the efficient management of irrigation and water delivery. In this study, the proportional–integral–derivative (PID) controller was implemented in both the HEC-RAS boundary condition, as an internal model, and MATLAB, as an external model. In the latter, the Hydrologic Engineering Center’s (HEC) River Analysis System (HEC-RAS) mod
Angular correlations between heavy quarks provide a unique probe of the quark-gluon plasma created in ultrarelativistic heavy-ion collisions. Results are presented of a measurement of the azimuthal angle correlations between muons originating from semileptonic decays of heavy quarks produced in 5.02 TeV Formula Presented and Formula Presented collisions at the LHC. The muons are measured with tran
Hypertension affects more than one billion people worldwide. Here we identify 113 novel loci, reporting a total of 2,103 independent genetic signals (P < 5 × 10−8) from the largest single-stage blood pressure (BP) genome-wide association study to date (n = 1,028,980 European individuals). These associations explain more than 60% of single nucleotide polymorphism-based BP heritability. Comparing to
Background: Exertional breathlessness is a cardinal symptom of cardiorespiratory disease. Research Question: How does breathlessness abnormality, graded using normative reference equations during cardiopulmonary exercise testing (CPET), relate to self-reported and physiologic responses in people with chronic airflow limitation (CAL)? Study Design and Methods: An analysis was done of people aged ≥
The recent “Conscious Turing Machine” (CTM) proposal offered by Manuel and Lenore Blum aims to define and explore consciousness, contribute to the solution of the hard problem, and demonstrate the value of theoretical computer science with respect to the study of consciousness. Surprisingly, given the ambitiousness and novelty of the proposal (and the prominence of its creators), CTM has received
Flow harmonic coefficients, vn, which are the key to studying the hydrodynamics of the quark-gluon plasma (QGP) created in heavy-ion collisions, have been measured in various collision systems and kinematic regions and using various particle species. The study of flow harmonics in a wide pseudorapidity range is particularly valuable to understand the temperature dependence of the shear viscosity t
A key aim of the HighNESS project for the European Spallation Source is to enable cutting-edge particle physics experiments. This volume presents a conceptual design report for the NNBAR experiment. NNBAR would exploit a new cold lower moderator to make the first search in over thirty years for free neutrons converting to anti-neutrons. The observation of such a baryon-number-violating signature w
The migration of large populations has had significant importance on historical and contemporary societies. Since mass migration is a multifaceted phenomenon that significantly impacts both places of origin and destination, shaping the lives of those directly and indirectly involved, it has drawn extensive research attention. Much of the economic history literature has focused on the Age of Mass M
Berlin är för många svenskar ett populärt utflyktsmål, en världsstad med dramatisk historia på överkomligt avstånd. Om en sådan stad finns självfallet många hyllmeter skrivet, inte minst kombinationer av reseguide och historiebok. Senast i raden är John Kampfners 400-sidiga In Search of Berlin: The Story of a Reinvented City (Atlantic Books 2023). Kampfner är en brittisk författare, journalist och
1920-talet förefaller vara ett kärt årtionde med tanke på att det har många namn: det glada 20-talet, the roaring twenties, jazzåldern, cocktailepoken. Det är ett emellertid ett årtionde som ofta hamnar i skuggan av 30- och 40-talens våldsorgier och som därmed är väl värt att belysa lite extra. Det är just vad två erfarna lundahistoriker med imponerande överblick av 1900-talet, Klas-Göran Karlsson
Anne Applebaum lyser likt en amerikansk frihetsgudinna med sin fackla väg för liberala krafter i ett demokratiskt skymningslandskap; hennes förra bok hette just Demokratins skymning (2020) (recenserad av undertecknad i Statsvetenskaplig Tidskrift nr 1 2021). Nu är hon aktuell med en ny stridsskrift, Autocracy, Inc.: The Dictators Who Want to Run the World (Allen Lane 2024). Den handlar om auktorit
Importance: Identification of individuals at high risk for atherosclerotic cardiovascular disease within the population is important to inform primary prevention strategies. Objective: To evaluate the prognostic value of routinely available cardiovascular biomarkers when added to established risk factors. Design, Setting, and Participants: Individual-level analysis including data on cardiovascular
Berlin is a major tourist destination, a world city with a dramatic history. Many shelf meters have been written about it, not least combinations of travel guide and history book. The latest contribution of this kind is John Kampfner’s in Search of Berlin: The Story of a Reinvented City (London: Atlantic Books 2023, 400 pages). Kampfner is a British author, journalist and documentary maker with a
Without intervention, cardiac arrhythmias pose a risk of fatality. However, timely intervention can be challenging in environments where transporting a large, heavy defibrillator is impractical, or emergency surgery to implant cardiac stimulation devices is not feasible. Here, we introduce an injectable cardiac stimulator, a syringe loaded with a nanoparticle solution comprising a conductive polym
