This article addresses the problem of multi-target localization from acoustic time delay measurements in a 3-D underwater environment, taking into account the depth-dependent sound speed of the underwater wave propagation. Specifically, we formulate the problem as an optimal mass transport (OMT) optimization over a grid of potential candidate positions. By exploiting an iterative refinement approa
Repair and replacement strategies using cell replacement or viral gene transfer for neurologic diseases are becoming increasingly efficacious with clinically meaningful benefits in several conditions. An increased understanding of disease processes opens up opportunities for genetic therapies and precision medicine methods aiming at disease modification or repair of lesioned neurologic structures.
A person’s life chances and quality of life depend on social class distinctions, but more so on the region one grew up in. Perspectives of the ‘urban’ or ‘metropolitan’ are a starting point when discussing geographical inequalities vis-à-vis rural, peripheral regions. How disrupting these problems and challenges are on the one (urban) and the other (rural) end of the geographical scope depends on
BACKGROUND: Anastomotic leakage after rectal cancer surgery is linked to reduced survival and higher recurrence rates. While an aggravated inflammatory response may worsen outcomes, few studies have explored the combined effects of leakage and inflammation.METHODS: This is a retrospective multicenter cohort study including patients operated with anterior resection for rectal cancer in Sweden durin
The labor market integration of migrants, focusing on employment and job quality, differs notably across Southern and Continental-Northern European nations, often involving trade-offs. Nonetheless, little is known about whether these diverse migrant inclusion models in European labor markets extend to the combination of employment and overeducation. Additionally, the role of gender in this context
The term “charisma” is recognized as sociology's most successful export to common speech. While sociologists habitually dismiss popular uses of the word, we address its vernacularity head on as a worthy object of study and as a potential resource for conceptual development. Using machine learning, we locate “charisma” within the wider discursive field out of which it arises (and continues to arise

BACKGROUND Reusing anaesthesia infusion-set components may reduce the climate impact from plastic waste and discarded medications. Infusion-set contents can be shielded from patient contact by single use of an infusion line fitted with dual antireflux valves, preventing retrograde entry of microorganisms, and eliminating the risk for patient-to-patient cross-contamination. However, infusion-set co
This paper investigates the use of decentralised control architectures with heterogeneous dynamics for improving performance in large-scale systems. Our focus is on two well-known decentralised approaches; the 'predecessor following' and 'bidirectional' architectures for vehicle platooning. The former, utilising homogeneous control dynamics, is known to face exponential growth in disturbance ampli
It is often argued that anisogamy causes alternative reproductive tactics (ARTs) to be more common in males than females. We challenge this view by pointing out logical flaws in the argument. We then review recent work on the diversity of female ARTs, listing several understudied types such as solitary versus communal breeding and facultative parthenogenesis. We highlight an important difference b
Background and purpose: Traumatic brain injury (TBI) is a major source of health loss and disability worldwide. Accurate and timely diagnosis of TBI is critical for appropriate treatment and management of the condition. Neuroimaging plays a crucial role in the diagnosis and characterization of TBI. Computed tomography (CT) is the first-line diagnostic imaging modality typically utilized in patient
Background: The role of prostate-specific antigen (PSA) testing in prostate cancer (PCa) screening has evolved over recent decades with multiple randomized controlled trials (RCTs) spurring guideline changes. At present, controversy exists due to the indolent nature of many prostate cancers and associated risks of overdiagnosis and overtreatment. This review examines major RCTs evaluating PSA scre
Background: Suicidal behaviors are prevalent public health concerns, and we need to improve our predictive ability to better inform prevention efforts. Methods: Using nationwide longitudinal Swedish registers, we included 344,490 males and 323,177 females born 1982–1990 with information on genetic liability and environmental exposures from birth to age 16: perinatal variables, parental psychopatho
Background: Global supply chains are confronted with the challenge of ensuring on-time deliveries while simultaneously enhancing supply chain resilience. Conventional methods aim to address the complexities of modern supply chains, promoting the transition to intelligent and data-driven strategies. Methods: This research represents an innovative methodology for predicting the risk of late deliveri
Multi-functional molecules with spirocyclic acetal structures have recently emerged as attractive monomers to prepare high-performance polymers, which may subsequently be de-polymerized and recycled under specific physicochemical conditions. Spirocyclic acetal structures can be formed by condensation of a suitable aldehyde or ketone with a polyol so that the functionalities necessary for the polym
Dimethyl ether (DME) is promising as an additive for co-firing with ammonia (NH3) to solve the problem of its low reactivity combustion. However, the combustion modeling of blended fuels is challenging, and previous efforts primarily relied on the adjustment of rate constants for key reactions to bridge the gap between experiments and simulations. In the present work, ab initio kinetic studies wer
Filter exchange imaging (FEXI) is a double diffusion-encoding (DDE) sequence that is specifically sensitive to exchange between sites with different apparent diffusivities. FEXI uses a diffusion-encoding filtering block followed by a detection block at varying mixing times to map the exchange rate. Long mixing times enhance the sensitivity to exchange, but they pose challenges for imaging applicat
