The dimension of a quantum state is traditionally seen as the number of superposed distinguishable states in a given basis. We propose an absolute, i.e., basis-independent, notion of dimensionality for ensembles of quantum states. It is based on whether a quantum ensemble can be simulated with states confined to arbitrary lower-dimensional subspaces and classical postprocessing. In order to determ
Titanium alloys are difficult-to-machine materials given their high strength, the high temperatures generated, and the naturally short contact length that combined result in rapid tool wear. Different machining strategies can be employed to cope with the low machinability. This study investigates the machining performance using different cooling and lubrication methods during down face milling of
Transmission electron microscopy (TEM) is an atomically resolved technique that allows for in depth analysis of the properties of materials by irradiating a thin sample with high energy electrons and detecting the signal imparted on, and generated by, the electron beam as it passes through. However, due to the strong interaction between electrons and matter, the sample will not remain unperturbed
Background: Certain species from the normal respiratory tract microbiota have recently been proposed to positively influence human health. Corynebacterium propinquum and C. pseudodiphtheriticum (Corynebacteria) are two Gram-positive species that frequently colonize the upper respiratory tract and strongly associate with a reduced incidence of respiratory tract infections. The specific role of Cory
Bimetallic nanoparticles exhibit unique physicochemical characteristics that often translateinto functional properties surpassing those of their monometallic counterparts. The abilityto precisely tailor these characteristics enables fine-tuning of their properties for targetedapplications. This doctoral thesis investigates the engineering of bimetallic nanoparticlesvia spark ablation, a continuous
Electrons photoemitted by extreme ultraviolet attosecond pulses derive spatially from the first few atomic surface layers and energetically from the valence band and highest atomic orbitals. As a result, it is possible to probe the emission dynamics from a narrow 2D region in the presence of optical fields, as well as obtain elemental specific information. However, combining this with spatially-re
Semidefinite programs are convex optimization problems involving a linear objective function and a domain of positive-semidefinite matrices. Over the past two decades, they have become an indispensable tool in quantum information science. Many otherwise intractable fundamental and applied problems can be successfully approached by means of relaxation to a semidefinite program. This methodology is
The Bell-state measurement (BSM) is the projection of two qubits onto four orthogonal maximally entangled states. Here we first propose how to appropriately define more general BSMs, which have more than four possible outcomes, and then study whether they exist in quantum theory. We observe that nonprojective BSMs can be defined in a systematic way in terms of equiangular tight frames of maximally
Polycrystalline cubic boron nitride (pcBN) is a very promising tool material for turning martensitic stainless steels at high cutting speeds (vc > 200 m/min). The competitive advantage of pcBN over cemented carbide increases as the cutting speed is increased. Changing the speed might lead to a shift in the wear balance and hence the knowledge about tool wear below vc = 200 m/min might not be appli
Severe chronic rhinosinusitis with nasal polyps (CRSwNP), a form of diffuse bilateral (usually type 2) CRS, is a debilitating disease with a significant impact on quality of life (QoL). With novel knowledge and treatment options becoming available, there is a growing need to update or revise key definitions to enable communication across different specialties dealing with CRS, and to agree on nove
Background: A growing literature suggests associations between occupational pesticide exposure and respiratory health. In this study, we aimed to examine the association of exposure to insecticides, fungicides, and herbicides, individually and as a mixture, with respiratory health outcomes and rhinitis in avocado farmworkers from Michoacán, Mexico. Material and methods: We conducted a cross-sectio
Place branders express a desire for their work to aid in addressing crises such as climate change through sustainable developments that assist with brand positioning, yet little is known about how place branding professionals manage tensions and contradictions that arise between sustainability and investment development. This paper qualitatively explores how place branders talk about ecological su
Titanium alloys are known for being difficult to machine. Within the groups of Ti alloys, the machinability is reduced when going from the α-alloys, to α + β, and finally to near-β or β-alloys. Uncoated cemented carbide is traditionally used for machining these alloys and finding a suitable coating to improve the performance is a challenge due to the high strength of Ti alloys and the high chemica
Tunnel Field-Effect Transistors (TFETs) offer more energy efficient alternative to CMOS for design of low power circuits. In spite of this potential, circuits based on TFETs have not been experimentally demonstrated so far. In this letter, we explore TFET fabrication and basic functionality of n-TFET based circuits in the following configurations: a current mirror, a diode-connected inverter, and
Background: Communication is a key tool in the nursing profession. It is known that listeners are sensitive to the speaker's voice and interpret the speaker's intentions primarily from the non-verbal signal conveyed. Aim: To map and discuss the current state of knowledge and research evidence on professional voice use in health and nursing care. Design and Method: A scoping review adherent to the
