Endoscopic papillectomy for ampullary lesions of minor papilla

Background and Aims: Ampullary lesions (ALs) of the minor duodenal papilla are extremely rare. Endoscopic papillectomy (EP) is a routinely used treatment for AL of the major duodenal papilla, but the role of EP for minor AL has not been accurately studied. Methods: We identified 20 patients with ALs of minor duodenal papilla in the multicentric database from the Endoscopic Papillectomy vs Surgical

A joint venture : patients’ experiences with goal setting in rheumatology rehabilitation–a qualitative study

Purpose: To explore how patients with rheumatic musculoskeletal diseases (RMDs) perceive participation in the goal setting process prior to interdisciplinary rehabilitation. Methods: We conducted semi-structured interviews with 22 participants admitted to an interdisciplinary rehabilitation stay for patients with RMDs at two Danish rehabilitation centres. Qualitative content analysis was applied.

Physical fitness in male adolescents and atherosclerosis in middle age : A population-based cohort study

Objectives: To examine the associations between physical fitness in male adolescents and coronary and carotid atherosclerosis in middle age. Methods: This population-based cohort study linked physical fitness data from the Swedish Military Conscription Register during adolescence to atherosclerosis data from the Swedish CArdioPulmonary bioImage Study in middle age. Cardiorespiratory fitness was as

Sex Differences in the Effectiveness of First-Line Tumor Necrosis Factor Inhibitors in Psoriatic Arthritis : Results From the European Spondyloarthritis Research Collaboration Network

Objective: Women with psoriatic arthritis (PsA) may have reduced tumor necrosis factor inhibitor (TNFi) effectiveness compared to men. We examined sex differences in treatment response and retention rates during 24 months of follow-up among patients with PsA initiating their first TNFi. Methods: Data from patients with PsA across 13 European Spondyloarthritis Research Collaboration Network registr

Spatial Aberrations in High-Order Harmonic Generation

We investigate the spatial characteristics of high-order harmonic radiation generated in argon and observe cross-like patterns in the far field. An analytical model describing harmonics from an astigmatic driving beam reveals that these patterns result from the order and generation position-dependent divergence of harmonics. Even small amounts of driving field astigmatism may result in cross-like

MULTI-DIMENSIONAL FEEDFORWARD CONTROLLER AT MAX IV

Feedforward control loops are used in numerous applications to correct process variables. While feedforward control loops correct process variables according to the expected behavior of a system at any given setpoint, feedback loops require measurements of the output to correct deviations from the setpoint. At MAX IV, a generic multi-dimensional input and output feedforward controller was implemen

A Technique to Increase the Linearity of the Bootstrapped Switch

We present a detailed investigation into a source of distortion that affects the classic bootstrapped switch. Our analysis reveals that the transition phase between track mode and hold mode is a critical factor in causing the distortion. To address this issue, we propose a novel technique that effectively mitigates the problem. Our results, based on simulations conducted using a 22-nm FDSOI CMOS p

Privacy Preserving Localization via Coordinate Permutations

Recent methods on privacy-preserving image-based localization use a random line parameterization to protect the privacy of query images and database maps. The lifting of points to lines effectively drops one of the two geometric constraints traditionally used with point-to-point correspondences in structure-based localization. This leads to a significant loss of accuracy for the privacy-preserving

AIRR-C IG Reference Sets : curated sets of immunoglobulin heavy and light chain germline genes

Introduction: Analysis of an individual’s immunoglobulin (IG) gene repertoire requires the use of high-quality germline gene reference sets. When sets only contain alleles supported by strong evidence, AIRR sequencing (AIRR-seq) data analysis is more accurate and studies of the evolution of IG genes, their allelic variants and the expressed immune repertoire is therefore facilitated. Methods: The

Doubly-Block Circulant Kernel Matrix Exploitation in Convolutional Accelerators

In this paper, we present a novel algorithmic and hardware co-design approach specifically tailored for efficient 2D convolution implementations, a crucial operation in convolutional neural networks (CNNs). Our method addresses the limitations of existing software-based solutions and hardware-based architectures, delivering significant improvements in asymptotic behavior for generic convolution ca

A Floating-Point 16 × 16 SVD Accelerator for Beyond-5G Large Intelligent Surfaces

Beyond-5G wireless communication systems will feature advanced, key technologies such as large intelligent surfaces (LISs) composed of a very large number of antenna elements. The concomitant tremendous data rate requirements, due to the communication between these antennas, necessitate careful algorithm-architecture codesign. This paper presents an application-specific integrated circuit (ASIC) a

The loss of OH maser emission in the early stage of Post-AGB evolution

Based on the results of an on-going monitoring program of 1612 MHz OH masers in OH/IR stars, we determined a lifetime encompassing late AGB and early post-AGB evolution of at least 4500 years. Fading of the OH masers observed with the Nançay Radio Telescope is detected in several post-AGB OH/IR stars on timescales of decades, while AllWISE/NEOWISE light curves taken almost in parallel show diverse

Integrated millimeter Wave CMOS Power Amplifiers for 5G Systems

The anticipated continuation of the last three decades of growth of global demand for high-speed high-coverage mobile data, calls for massive investments in cellular infrastructure, for the ongoing roll out of the fifth generation of mobile systems, but also later for the sixth generation. A key enabler, for the high-speed part, is for the cellular system to move up in frequency and support commun

Mahalla in Uzbekistan: An Embodiment of Muslim Values of Neighbourliness and Mutual Support

The main purpose of this brief reflection is to examine the relationship between (a) Muslim communal values of neighborliness, mutual support and responsibility for those living together in a defined, spacial community and b)the built environment and structures of mosques and community gathering spaces, with a focus on how the existence of such a built environment and infrastructure helps to devel

Youth handball concussion prevention strategies: A workshop-based study with experts and end users

Sport-related concussion (SRC) is a serious injury in youth team sports, including handball. While research on the prevention of SRC has made progress over the past 5 years, prevention strategies are lacking in handball. The aim was to explore and develop strategies focusing on information, rules and training that may prevent concussion in youth handball by incorporating knowledge from experts and

Multi-fidelity reduced-order surrogate modelling

High-fidelity numerical simulations of partial differential equations (PDEs) given a restricted computational budget can significantly limit the number of parameter configurations considered and/or time window evaluated. Multi-fidelity surrogate modelling aims to leverage less accurate, lower-fidelity models that are computationally inexpensive in order to enhance predictive accuracy when high-fid

Uncertainty quantification for nonlinear solid mechanics using reduced order models with Gaussian process regression

Uncertainty quantification (UQ) tasks, such as sensitivity analysis and parameter estimation, entail a huge computational complexity when dealing with input-output maps involving the solution of nonlinear differential problems, because of the need to query expensive numerical solvers repeatedly. Projection-based reduced order models (ROMs), such as the Galerkin-reduced basis (RB) method, have been
