Effects of an Annular Piston Bowl-Rim Cavity on In-Cylinder and Engine-Out Soot of a Heavy-Duty Optical Diesel Engine

The effect of an annular, piston bowl-rim cavity on in-cylinder and engine-out soot emissions is measured in a heavy-duty, optically accessible, single-cylinder diesel engine using in-cylinder soot diagnostics and exhaust smoke emission measurements. The baseline piston configuration consists of a right-cylindrical bowl, while the cavity-piston configuration features an additional annular cavity t

The two sides of the coin : joint project leader interaction in university-industry collaboration projects

This article focuses on how academic and industrial leaders view central aspects of the initiation, collaboration process, and the outcomes in government-funded R&D projects. In much previous work on university-industry collaborations (UICs), universities or researchers and/or firms have been studied without any direct reference to the other party, thus neglecting the fact that the motivations

Reflection-Based Source Inversion for Sparse Imaging of Low-Loss Composite Panels

This article presents a bistatic reflection-based imaging technique for electromagnetic testing of conductor-backed composite panels, which is based on an inverse formulation of the numerical problem at hand, and technically extends a previously demonstrated transmission-based system. The technique exploits the a priori assumption of pixel-based sparsity and retrieves the final image using data fr

Low-temperature nanoscale heat transport in a gadolinium iron garnet heterostructure probed by ultrafast x-ray diffraction

Time-resolved x-ray diffraction has been used to measure the low-temperature thermal transport properties of a Pt/Gd3Fe5O12//Gd3Ga5O12 metal/oxide heterostructure relevant to applications in spin caloritronics. A pulsed femtosecond optical signal produces a rapid temperature rise in the Pt layer, followed by heat transport into the Gd3Fe5O12 (GdIG) thin film and the Gd3Ga5O12 (GGG) substrate. The

Distributed and Scalable Uplink Processing for LIS : Algorithm, Architecture, and Design Trade-Offs

The Large Intelligent Surface (LIS) is a promising technology in the areas of wireless communication, remote sensing and positioning. It consists of a continuous radiating surface located in the proximity of the users, with the capability to communicate by transmission and reception (replacing base stations). Despite its potential, there are numerous challenges from an implementation point of view

Low numbers of COVID-19 in Swedish pediatric oncology patients during the first pandemic year despite an open society

Background: Sweden adopted a different strategy than many other countries to combat the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic and kept most schools open. Initial reports from China suggested that coronavirus disease 2019 (COVID-19) was milder in children compared to adults, but there was a lack of data from immunocompromised children. Therefore, we investigated the

Gendering Morality and Providing a Feminized Ethics of Care: Welfare, Crises, and Tình Cảm in Contemporary Vietnam

Focusing on welfare challenges and crises encountered by women in contemporary Vietnam, this article examines the gendering of morality and the ways in which a feminized ethics of care is entangled with women’s practice of the social capacity tình cảm (sentiments/feelings/emotions). Drawing on data from the Industrial Zones of northern Vietnam, the article highlights how low-income workers are ren

Gap Distance Between Pearl Chains in Acoustic Manipulation

We present a theory to compute the stable gap (interparticle) distance between particle chains collected in the pressure node of an acoustic standing wave. The primary and secondary acoustic radiation forces are the two competing forces that act on the particles during the particle chain formation. The stable equilibrium distance between two chains is reached when both forces are in balance. Most

Nanostructure-property relationship of two perfluorinated sulfonic acid (PFSA) membranes

The physicochemical properties of perfluorinated sulfonic acid (PFSA) polymers are closely correlated with their nanostructure. However, their real nano-structural morphology is still controversial because it is difficult to observe their accurate morphology at the nanoscale. Moreover, studies on the nanostructures of the PFSA membranes have been mainly focused on the ionic domain. On this basis,

Estimating the accuracy of calculated electron paramagnetic resonance hyperfine couplings for a lytic polysaccharide monooxygenase

Lytic polysaccharide monooxygenases (LPMOs) are enzymes that bind polysaccharides followed by an (oxidative) disruption of the polysaccharide surface, thereby boosting depolymerization. The binding process between the LPMO catalytic domain and polysaccharide is key to the mechanism and establishing structure-function relationships for this binding is therefore crucial. The hyperfine coupling const

Monitoring treatment with 5-Azacitidine by flow cytometry predicts duration of hematological response in patients with myelodysplastic syndrome

5-Azacitidine (AZA) therapy is used in high-risk myelodysplastic syndrome (MDS) patients who often show abnormalities in their immunophenotype. We explored the potential impact of AZA on these immunophenotypic abnormalities in serial bone marrow studies performed in 81 patients from five centers. We compared the immunophenotypic features before and after therapy with AZA, established definitions c

Different sensitivity of a panel of Rhizophagus isolates to AMF-suppressive soils

Suppression of the activity of arbuscular mycorrhizal fungi (AMF) in unsterile soils, as determined by transfer of 33P from soils to plants, has been recently demonstrated, and soils differ in their degree of suppressiveness. The previous experiments included only one R. irregularis isolate, BEG87. The aim of this study was to analyze the sensitivity to suppression of different cultivated AMF isol

Role of machine and organizational structure in science

The progress of science increasingly relies on machine learning (ML) and machines work alongside humans in various domains of science. This study investigates the team structure of ML-related projects and analyzes the contribution of ML to scientific knowledge production under different team structure, drawing on bibliometric analyses of 25,000 scientific publications in various disciplines. Our r

Consequences of partially recessive deleterious genetic variation for the evolution of inversions suppressing recombination between sex chromosomes

The evolution of suppressed recombination between sex chromosomes is widely hypothesized to be driven by sexually antagonistic selection (SA), where tighter linkage between the sex-determining gene(s) and nearby SA loci is favored when it couples male-beneficial alleles to the proto-Y chromosome, and female-beneficial alleles to the proto-X. Despite limited empirical evidence, the SA selection hyp

Estimation of recent peat accumulation with tree saplings

The purpose of this paper is to develop an approach to estimate peat accumulation rates (PAR) over recent decades based on the age and burial depths of roots from pine sapling and to use the newly developed approach to estimate spatial variations of PAR. To this end, we sampled 120 pine saplings growing in three plots at Rėkyva peatland in Lithuania and accounted for the microtopography around eac
