Oxidation and Reconstructions of Alloy Model Catalysts : Platinum-Rhodium and Palladium-Gold
Alloys and bimetallic systems have shown many advantages in heterogeneous catalysis, but the details of their catalytic functions are not always known. For instance, the atomic details about surface reconstructions under catalytic reaction conditions, or which phases that are high-active or low-active. Furthermore, the model catalysts studied in laboratories often differ a lot from the industrial
Optimal Inverse Design Based on Memetic Algorithms - Part 1 : Theory and Implementation
A memetic framework for optimal inverse design is proposed by combining a local gradient-based procedure and a robust global scheme. The procedure is based on method-of-moments matrices and does not demand full inversion of a system matrix. Fundamental bounds are evaluated for all optimized metrics in the same manner, providing natural stopping criteria and quality measures for realized devices. C
Feasibility to use whole-genome sequencing as a sole diagnostic method to detect genomic aberrations in pediatric B-cell acute lymphoblastic leukemia
Introduction: The suitability of whole-genome sequencing (WGS) as the sole method to detect clinically relevant genomic aberrations in B-cell acute lymphoblastic leukemia (ALL) was investigated with the aim of replacing current diagnostic methods. Methods: For this purpose, we assessed the analytical performance of 150 bp paired-end WGS (90x leukemia/30x germline). A set of 88 retrospective B-cell
A continuum damage model for creasing and folding of paperboard
A continuum damage framework is proposed for modelling the delamination process occurring in paperboard during mechanical loading. The main application of interest is line creasing and subsequent line folding used in package forming. To adequately capture creasing and folding, a continuum damage framework that uses a single isotropic damage variable that evolves with the plastic strains associated

TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf
We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright (T = 8.5 mag), high proper motion (∼200 mas yr−1), low metallicity ([Fe/H]≈−0.28) K-dwarf with a mass of 0.68 ± 0.05 M and a radius of 0.67 ± 0.01 R. We obtain photometric follow-up observations with a variety of facilities, and we use these data sets to d
Constraining the K ¯ N coupled channel dynamics using femtoscopic correlations at the LHC
The interaction of K - with protons is characterised by the presence of several coupled channels, systems like K ¯ n and π Σ with a similar mass and the same quantum numbers as the K - p state. The strengths of these couplings to the K - p system are of crucial importance for the understanding of the nature of the Λ (1405) resonance and of the attractive K - p strong interaction. In this article,

Developmental pathways of repetitive non-suicidal self-injury: predictors in adolescence and psychological outcomes in young adulthood
BackgroundMuch longitudinal research has been carried out on non-suicidal self-injury (NSSI) during the last decades, but there still is a lack of studies of the individual developmental pathways of NSSI from adolescence into young adulthood. The aim of the present study was to investigate individual developmental pathways of repetitive non-suicidal self-injury (repNSSI) from adolescence into youn
Ordering the Social : The History of Knowledge and the Usefulness of (Studying) Social Taxonomies
During the twentieth century, a number of actors and institutions acrossthe global north set out to develop hierarchical social taxonomies of their national populations. Mainly used for the making of statistics, these divisions soon came to be influential in policy and public debates. Using mainly Swedish examples, this article offers new ways of understanding social taxonomies, thereby adding ins
Unfolding the Dynamics of Refugees’ Entrepreneurial Journey in the Aftermath of Forced Displacement
Despite their detrimental circumstances, the number of refugee-owned businesses is on the rise—a situation referred to as “the paradox of refugee entrepreneurship.” However, a key question is how refugees, having undergone extreme life disruption due to war, conflict, and forced displacement, fare as entrepreneurs in their host country. Extant studies do not address this question, as they primaril

Variables are valuable : making a case for deductive modeling
Following the quantitative turn in linguistics, the field appears to be in amethodological “wild west” state where much is possible and new frontiers arebeing explored, but there is relatively little guidance in terms of firm rules orconventions. In this article, we focus on the issue of variable selection in regression modeling. It is common to aim for a “minimal adequate model” and eliminate “no
Not just frequency, not just modality : Production and perception of English semi-modals
We review reduction and contraction in modalizing expressions of the type V-to- Vinf from the perspective of production, perception and mental representation.A corpus study of spoken American English shows reduction/contraction asa continuous process which is subject to phonological and communicative constraints. Generally, reduction (articulatory ease) is restricted by a tendencyto retain cues to
Converging variations and the emergence of horizontal links : To-contraction in American English
The guiding question of this paper is how (horizontal) connections are established when new items enter the network of constructions. It presents a quantitative, corpus-based study of the development of to-contraction (e.g. want to > wanna) in American English since the 19th century. From a plethora of earlier forms, gonna, wanna and gotta emerge, first as representations of phonetic reduction, bu
Chunking or predicting : Frequency information and reduction in the perception of multi-word sequences
Frequently used linguistic structures become entrenched in memory; this is often assumed to make their consecutive parts more predictable, as well as fuse them into a single unit (chunking). High frequency moreover leads to a propensity for phonetic reduction. We present a word recognition experiment which tests how frequency information (string frequency, transitional probability) interacts with
A spatially explicit model of landscape pesticide exposure to bees : Development, exploration, and evaluation
Pesticides represent one of the greatest threats to bees and other beneficial insects in agricultural landscapes. Potential exposure is generated through compound- and crop-specific patterns of pesticide use over space and time and unique degradation behavior among compounds. Realized exposure develops through bees foraging from their nests across the spatiotemporal mosaic of floral resources and
