Quest2ROS2 is an open-source ROS2 framework for bi-manual teleoperation designed to scale robot data collection. Extending Quest2ROS, it overcomes workspace limitations via relative motion-based control, calculating robot movement from VR controller pose changes to enable intuitive, pose-independent operation. The framework integrates essential usability and safety features, including real-time RV
Abstract – Introduction: – Severe symptoms and disability may remain after upper and lower limb nerve injuries with an additional risk of persistent pain and consumption of pain medication.Objectives: – To examine whether upper and lower limb nerve injuries, potentially causes of pain, are associated with risk of using pain medication.Methods: – Drug use at an individual level was analysed in a la
Objectives To assess the performance of the ALL IN TRIPLEX rapid antigen-based test for SARS-CoV-2, influenza A, influenza B, and respiratory syncytial virus. We focus on the potential of the test to be used in acute clinical settings as a marker of infectiousness, by determining the sensitivity at different real-time PCR cycle threshold (Ct) levels, as well as the quantity of absorbed viral RNA n
AimTo characterize the intracanal microbiota and identify key microbial taxa and functional pathways associated with regenerative endodontic treatment (RET) outcomes.MethodologyIn this observational cohort study, 196 samples were collected at five time points from external tooth surfaces (T1, T4) and root canals (T2, T3, T5). The V3–V4 hypervariable region of 16S rRNA gene was amplified and sequen
Freshwater blooms of the microcystin-producing (toxigenic) cyanobacterium Microcystis may cause severe damage to human health and the environment. However, toxigenic and non-toxigenic strains co-exist within single blooms, and microcystin concentration in the water varies throughout the season. We hypothesized that strains that produce and do not produce microcystins represent different genotypes.
Understanding and manipulating micelle morphology is key to exploiting surfactants in applications from templating mesoporous materials to formulation of creams and lipid particles for drug delivery. The drive to replace toxic organic solvents in extractions, syntheses and materials processing as well as the shift toward use of natural components in formulations has led to increasing demand for su
Sundaland, a subcontinent situated in the Indo-Malay Archipelago, is characterized by a dynamic climatic, geological, and geographical history and a correspondingly diverse biota. The distribution of this biota follows complex biogeographical patterns, with high levels of local endemism and frequent instances of hidden diversity—greater genetic differentiation than expected based on phenotype. Bio
Hur beskriver personer med normbrytande funktionalitet sin sexualitet, och vilka hinder möter de i sina försök att leva ut sin sexualitet på egna villkor? Denna artikel analyserar sådana erfarenheter genom ett intersektionellt och cripteoretiskt perspektiv, där funktionalitet behandlas som en analytisk kategori i egen rätt. Genom kvalitativa intervjuer med 65 personer med olika typer av normbrytan
When machining titanium alloys, diffusion and oxidation are key wear mechanisms that affect conventional machining. At the microscale, however, the knowledge about tool-workpiece interactions remains limited, partly due to the challenge of analysing wear phenomena in microtools. This study investigates tool wear mechanisms during micromilling of Ti6Al4V by employing cross-sectional analysis of wor
Plastic deformation remains a critical tool deterioration mechanism that limits the performance of cemented carbide cutting tools in high-speed machining. Reliable detection and prediction of its onset are essential for optimizing tool performance and machining process stability. Building on the multi-sensor framework presented in Part 1, this study (Part 2) focuses on developing machining methodo
Stainless steels have a wide range of applications due to their high corrosion resistance and strength. However, their machining remains challenging, hence limiting the performance and sustainability of machining operations. Tool wear is one of such key limiting factors, which is attributed to low thermal conductivity, work-hardening tendency and high forces in machining. In this study the perform
Ti (C, N)-based cermets are widely employed in continuous finishing operations of metal cutting owing to their high hardness, superior oxidation resistance, and chemical stability compared to WC-Co based carbides. Nevertheless, their use in interrupted cutting processes such as milling remains restricted due to their inherently low fracture toughness, which often results in brittle-like failure. I
Plastic deformation remains a critical tool deterioration mechanism that limits the performance of cemented carbide cutting tools in high-speed machining. Reliable detection and prediction of its onset are essential for optimizing tool performance and machining process stability. This paper, the first in a two-part study, presents a multi-sensor framework for detecting and predicting the onset of
Rock-cutting processes are the backbone of the mining, oil and gas, civil engineering, and construction industries. Performance of such cutting operations is controlled by temperature-dependent phenomena of abrasion, phase transformations, and oxidation of tooling. This study develops a novel approach for the measurement of cutting temperature for the case of the rock cutting process in longitudin
This letter addresses the robustness of a prescribed-time observer for a class of nonlinear systems in the presence of disturbances and unmodeled dynamics. It is proven and demonstrated through simulations that the proposed observer completely rejects the effects of large bounded disturbances and unmodeled dynamics, enabling accurate estimation of both the states and the disturbances. Furthermore,
The evolving security landscape has renewed attention to integrate military and civil defence and preparedness into spatial planning. For decades, risk management in spatial planning has focused on natural hazards and accidents, typically disregarding antagonistic threats. The current geopolitical tensions demand a broader perspective that includes actor-driven threats to infrastructure and societ
Recovery from significant mental health issues is a multidimensional process, which can be considered from a range of perspectives. However, mental health services have traditionally been limited to addressing custodial and clinical aspects of recovery. This narrow view of recovery prioritizes physical safety and security while addressing symptoms via medical and psychological treatments. People l
A key consideration in the design of a new industrial site is the spatial arrangement of units with respect to required safety distances. Safety distance requirements are intended to reduce the risk of hazardous events escalating from their origin to other units as well as to limit the damage to particularly vulnerable targets (e.g., control rooms), and are typically based on industrial standards
Migraine treatments that target calcitonin gene-related peptide (CGRP) are widely used, but questions remain regarding their mechanisms and sites of action. Re-examination of the effects of CGRP in the trigeminovascular system has now refined our understanding of nociceptive CGRP signalling and underscores the importance of early therapeutic intervention.
Background Body dysmorphic disorder (BDD) is a debilitating and understudied psychiatric condition of largely unknown etiology. Emerging evidence suggests that BDD may be a familial and heritable disorder, but family studies of diagnosed individuals and their biological relatives are yet to be conducted. Methods We identified 4,857,049 individuals born in Sweden between 1960 and 2008 with informat
