Time-domain induced polarization (TDIP) data carry spectral information that can be used for petrophysical interpretation. At the same time, TDIP data can be collected in the field more efficiently than frequency-domain induced polarization (FDIP) data, thanks to the use of square-wave signals. However, TDIP field data are prone to noise, particularly strong near industrial installations and urban
Ouagadougou is a city with three million inhabitants and an increasing demand for water of sufficient quality. New boreholes are drilled to match demand, but their protection from anthropogenic contamination is insufficient. To assess the quality of urban groundwater in Ouagadougou for the first time, a total of 32 borehole water samples were collected and assessed for bacteriological and physicoc
Background: Parathyroidectomy is typically curative for primary hyperparathyroidism (PHPT) and may lead to health-related quality of life (HRQL) improvements. We aim to evaluate general and disease-specific HRQL changes in patients undergoing surgery for PHPT from their perspective. Methods: Patients completed three patient-reported outcome measure (PROM) surveys before and after surgery: (1) Worr
John Maynard Keynes was nominated for the Nobel Peace Prize in the 1920s for writing “The Economic Consequences of the Peace”. Yet, despite being highly ranked by the advisor of the Nobel Committee and placed on the shortlist, he did not win. This column brings out previously unused archival material from the Nobel Committee in Oslo to explore why. The Committee tended to withhold the Prize when c
Liquid-phase ammonia, a carbon-free alternative fuel, is increasingly being considered for improving overall efficiency, reducing system complexity, and lowering costs across various thermal applications such as engines, gas turbines, and burners. However, the physical properties of ammonia are far from usual carbon-based fuels as it is prone to flash boiling upon injection. Therefore, experimenta
Modern solid-state klystron modulators generate high-voltage, high-power pulses by discharging energy stored in a capacitor bank. Such modulators require at least one capacitor charging unit supplying the energy released in pulsing. Traditional capacitor charging structures rely on AC/DC front-end units based on passive diode rectifiers in conjunction with high-frequency resonant converters. Howev
To generate the required antiproton beam intensity for the FAIR PANDA experiment, a dedicated proton LINAC (pLINAC) for the FAIR accelerator chain is being constructed. Klystron modulators are power converters within the high-power RF system of the pLINAC. Here, seven modulator systems with a nominal pulse power amplitude of 115 kV / 54 A, an effective pulse width of 360 µs and a pulse repetition
Martian carbonate-bearing rocks are compelling targets for exploration because they preserve detailed records of past aqueous processes, climate, and habitability. The Margin unit in Jezero crater is a distinct olivine- and carbonate-bearing unit stratigraphically underlying the western fan, lining the inner margin of the western crater rim and has a contested origin. Perseverance spent ∼350 sols
Objective: In primary health care in southern Sweden, interprofessional medication reviews are conducted, to a limited extent, for patients living independently, with the purpose of optimising their pharmacological treatment. These medication reviews have identified and addressed many important issues regarding the patients’ medication. However, there is limited knowledge regarding the participati
Conversational agents are increasingly being introduced in healthcare to enhance access to healthcare and address limited healthcare resources. The aim of this study was to explore experiences of a conversational agent for symptom checking and triage tool assessing the urgency and appropriate level of care implemented in public healthcare from a cognitive accessibility perspective. With a Particip
This paper presents the characterisation and testing of the first wafer-scale monolithic stitched sensor (MOSS) prototype developed for the ALICE ITS3 upgrade that is to be installed during the LHC Long Shutdown 3 (2026–2030). The MOSS chip design is driven by the truly cylindrical detector geometry that imposes that each layer is built out of two wafer-sized, bent silicon chips. The stitching tec
Background Completion axillary lymph node dissection (cALND) is often recommended for patients with isolated tumour cells (ITCs) or micrometastases in the sentinel lymph node (SLN) or target lymph node (TLN) to assess the definite nodal tumour burden after neoadjuvant chemotherapy (NACT). The aim of this study was to investigate the upgrade of N stage by cALND in patients with low-volume metastase
Disclosed is a method (310) for providing operational feedback during power transfer in a wireless power transfer system. The wireless power transfer system comprises a power transmit device arranged to transfer power over an inductive wireless power transfer interface operating at a transmit frequency to a power receive device. The wireless power transfer system is adapted to transfer information
AimTreatment of complex anal fistulae remains a significant challenge for physicians and patients. A sphincter-preserving technique with bioactive platelet-rich fibrin matrix is one option. This three-year study aimed to evaluate the efficacy of bioactive platelet-rich fibrin matrix in treating complex anal fistulae.MethodThis retrospective study analysed data from 2019 to 2022 of patients diagnos
A search for the dimuon decay of the Higgs boson is presented based on pp collision data recorded by ATLAS during Run 3 of the Large Hadron Collider, corresponding to an integrated luminosity of 165 fb-1 at √s = 13.6 TeV. To enhance the sensitivity, the results are combined with those from Run 2. An excess of events over the background is observed with a significance of 3.4σ (2.5σ expected). The b
Extreme heat is a growing public health threat in tropical Africa, especially in Ghana where outdoor maximum daily temperatures (Tx) regularly exceed 35 °C. Vulnerability to heat is socially and economically differentiated, with pregnant women, young children, elderly people, and people with chronic health conditions most at risk. High proportions of these groups are found in hospitals, yet little
This paper explores the changing nature of social institutions and organizations for resource management on Ontong Java and their central role in maintaining livelihoods. Using detailed field data for three time periods, 1970-72, 1986 and 2006-07, and drawing on earlier secondary data, a longitudinal analysis of changes in governance and livelihoods is undertaken. Increased exploitation of marine
Water balance models provide insights into ongoing changes in the water cycle. Among them, monthly water balance models (MWBMs) are especially suitable for large-sample and global assessments, which are important for adaptation to global environmental change. This study evaluates monthly water balances from 14 models across more than 2,000 global catchments, comparing the modelś capacities to repr
This chapter discusses trade-offs that need to be struck while developing Unmanned Aircraft Systems (UAS) operations. Ten trade-offs are outlined, pertaining to technical systems, to human operators, and to the combined sociotechnical system in its operational and organizational environment, which have implications for Human-Systems Integration (HSI) in multiple phases of the systems engineering l
OBJECTIVES: To identify the lowest sensitivity and specificity that physicians and the general population consider acceptable for medical artificial intelligence (AI), relative to current human performance.METHODS: In a nationwide, cross-sectional survey in Sweden, 2025, random samples of 500 physicians and 500 adults from the general population were mailed a questionnaire presenting three vignett
