Electromagnetic degrees of freedom are instrumental in antenna design, wireless communications, imaging, and scattering. A large number of degrees of freedom enhance control in antenna design, influencing radiation patterns and directivity, while in communication systems, it links to spatial channels for increased data rates, reliability, and resolution in imaging. The correlation between computed

Humanity has long battled mosquitoes and the diseases they transmit—a struggle intensified by climate change and globalization, which have expanded mosquito ranges and the spread of associated diseases.1 Additionally, widespread insecticide resistance has reduced the efficacy of current control methods, necessitating new solutions.2,3 Nootkatone, a natural compound found in grapefruit, shows promi

Increasing concentrations of toxic pollutants and particulate matter are a major concern related to human health. The present work is structured into two phases; the first is aimed at understanding the O3–NOX–VOC sensitivity over Delhi during the lockdown period; the second phase examines the influence of dust-induced aerosol particles on air pollution during the lockdown period using satellite-de

We study two related universal anomalies of the spectral function of cuprates, so-called waterfall and high-energy kink features, by a combined cellular dynamical mean-field theory and angle-resolved photoemission study for the oxychloride NaxCa2-xCuO2Cl2 (Na-CCOC). Tracing their origin back to an interplay of spin-polaron and local-correlation effects both in undoped and hole-doped (Na-)CCOC, we

Objectives The objective of this study was to assess the completeness of registration of secondary preventive variables comparing on-site visits with telephone consultations during follow-up after myocardial infarction. Design This was an observational study based on the Swedish quality registry SWEDEHEART. Setting and outcome measures We analysed the proportion of missing values for major seconda

This study investigated the molecular basis of disease severity in acute pyelonephritis (APN), a common and potentially life-threatening bacterial infection. Two cohorts of infants with febrile urinary tract infection were included. Renal involvement was defined by DMSA scans and molecular disease determinants by gene expression analysis and proteomic screens, at diagnosis and after 6 mo. Innate i

Theoretical work suggests that reinforcement can cause the strengthening of prezygotic isolation in sympatry by mitigating the costs of maladaptive hybridization. However, only a handful of studies have simultaneously tested multiple predictions of this theory in natural populations. We investigated reinforcement in a mottled hybrid zone between the damselflies Ischnura elegans and Ischnura graell

If policy meets its intended goals or not is important in the context of energy transition. We explore if a policy, the EU Taxonomy, designed to foster green investments, meets its intent. We built an overall understanding about the EU Taxonomy by reviewing literature and EU Taxonomy documents. Additionally, we test constraints from the EU Taxonomy on CO2 emissions and on new investments in fossil

Background and Objectives: Temporomandibular disorders (TMDs) is an umbrella term for pain and dysfunction involving jaw muscles and/or the temporomandibular joint, with whiplash trauma suggested to be one risk factor. The aim was to evaluate prevalence and relative risk of TMDs in the acute and chronic stages after whiplash trauma. Databases and Data Treatment: This review was registered in Prosp

The leadership literature has been faulted for framing leaders (and followers) as rational and disembodied information processers. This chapter presents a review of studies that go against this tendency by focusing on how materiality, embodiment, and aesthetics are involved in leadership communication. A number of different perspectives are highlighted in relation to the three focal themes, as welThe leadership literature has been faulted for framing leaders (and followers) as rational and disembodied information processers.

This study is concerned with the shared object manipulation problem in a physical Human-Robot Interaction (pHRI) setting. In such setups, the operator manipulates the object with the help of a robot. In this paper, the operator is assigned with the lead role, and the robot is passively following the forces/torques exerted by the operator. We propose a controller that is free from the well-known tr

Poor survival for breast cancer in low- and middle-income countries is largely attributed to late-stage diagnosis and limited access to diagnostic tools. Therefore, we propose using point-of-care ultrasound (POCUS) as a low-cost diagnostic solution paired with a deep learning (DL) model for cancer detection. While using DL has shown great potential, it is crucial to ensure the trustworthiness of a

Den nya nationalistiska högern avfärdar FN, klimatavtal och universella mänskliga rättigheter. Sveriges regering har slagit in på samma väg, skriver Adam Almqvist och Anna Lundberg, forskare vid Lunds universitet.

BACKGROUND: Human diets account for 30% of greenhouse gas emissions (GHGE). Reporting dietary GHGE with or without energy standardization yields different outcomes, often resulting in conflicting conclusions regarding associations with micronutrient intake.OBJECTIVES: To compare methods of reporting dietary GHGE, with and without consideration of energy intake, and their respective associations wi

We present a novel acoustofluidic chromatography platform for high-throughput nanoparticle trapping and enrichment, with a focus on extracellular vesicles (EVs) from blood plasma. The system features a packed bed of polystyrene beads inside a rectangular glass capillary, acoustically actuated by a piezoelectric element. Using fluorescent polystyrene nanoparticles as small as 25 nm, we characterize

We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex (LG0,l) beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-pass cell. Beams with orders l=1−3 are generated by a spatial light modulator, which facilitates rapid and precise reconfiguration of the experimental conditions. 180 fs pulses with 610 uJ pulse energy are post-compressed to 44 fs u

High-order harmonic generation (HHG) in gases is inherently inefficient, prompting ongoing efforts to enhance the output of coherent table-top XUV sources. In this study, we investigate the influence of the laser pulse duration on HHG using a compact post-compression method featuring a bulk multi-pass cell. This setup enables tunable Fourier-limited pulse durations as short as 42 fs. We examine th
