Mechanical behavior of meniscus can be modeled using constitutive material models of varying complexity, such as isotropic elastic or fibril reinforced poroelastic (FRPE). However, the FRPE material is complex to implement, computationally demanding in 3D geometries, and simulation is time-consuming. Hence, we aimed to quantify the most suitable and efficient constitutive model of meniscus for sim

System level synthesis is a promising approach that formulates structured optimal controller synthesis problems as convex problems. This work solves the distributed linear-quadratic regulator problem under communication constraints directly in infinite-dimensional space, without the finite-impulse response relaxation common in related work. Our method can also be used to construct optimal distribu

Peak to average power (PAPR) reduction of OFDM signals is critical in order to improve power amplifier (PA) efficiency in base stations. For massive MIMO, the complexity of these methods can become a real bottleneck in implementing low power digital signal processing chains. In this work, we consider an antenna reservation technique, which uses a low complexity clipping method to reduce signal pea

We developed a process for enzyme-linked immunosorbent assay on a glass microchip via the use of a thin-layered microfluidic channel. This channel possesses a high aspect ratio (width/depth ∼200) and has an antibody layer immobilized directly on the channel surface. A depth of several microns and an excessive width and length (mm scale) of the channel provide a large-volume capacity (102 nL) and m

TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit transit timing variations (TTVs). Precise characterization of the planets’ masses and radii, orbital properties, and resonant behavior can test theories for the origins of planets orbiting close to their stars. Previous characterizatio

Eclipsing Binaries (EBs) are known to be the source of most ac- curate stellar parameters, which are important for testing theories of stellar evolution. With improved quality and quantity of observations using space tele- scopes like TESS, there is an urgent need for accuracy in modeling to obtain precise parameters. We use the soon to be released PHOEBE 2.3 EB modeling package to test the robust

Den 1 februari återinförs det ordensväsende som avskaffades under 1970-talet. Därmed blåser man nytt liv i ett belöningssystem som uppstod under frihetstiden, och som under århundradena speglat relationen mellan såväl Sverige och Europa som kungahuset och folket.

Context. We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 RJup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d orbit. Brown dwarfs and massive planets orbiting M dwarfs on short-period orbits are rare, but more have already been discovered than expected from planet formation models. TOI-519 is a valuable addition to this group of unlikely systems, an

This article concerns legal representatives’ negotiations around the principle of children’s best interests and children’s right to participation according to the Convention on the Rights of the Child, in cases of families applying for asylum in Sweden. Using material from nine interviews with children’s advocates, we analyse their strategies for obtaining narratives from children without putting

We present property probes, a mechanism for helping a developer interactively explore partial program analysis results in terms of the source program, and as the program is edited. A node locator data structure is introduced that maps between source code spans and program representation nodes, and that helps identify probed nodes in a robust way, after modifications to the source code. We have dev

We apply insights from the political economy of secession to analyse the early years of the Irish Free State (IFS). The IFS was fortuitous in a debt settlement that enabled it to begin its existence debt free while also receiving financial assistance to quell civil unrest. Yet the IFS was unable to continue to provide the welfare spending inherited from the old regime thereby exacerbating inequali

How do we develop artificial intelligence (AI) systems that adhere to the norms and values of our human practices? Is it a promising idea to develop systems based on the principles of normative frameworks such as consequentialism, deontology, or virtue ethics? According to many researchers in machine ethics – a subfield exploring the prospects of constructing moral machines – the answer is yes.

Background: Clinical Impression of Severity Index for Parkinson's Disease (CISI-PD) is a simple tool that can easily be used in clinical practice. Few studies have investigated the relationship between health-related quality of life and the CISI-PD. Objective: To analyze the association of CISI-PD scores with those of generic (EQ-5D-5L) and Parkinson's disease (PD) disease-specific (Parkinson's Di

The design of an adaptive controller with bounded L2-gain from disturbances to errors for linear time-invariant systems with uncertain parameters restricted to a finite set is investigated. The synthesis of the controller requires finding matrices satisfying non-convex matrix inequalities. We propose an approach for finding these matrices based on repeatedly linearizing the terms that cause the no
