Tuning and Analysis of Geometric Tracking Controllers on SO(3)

This paper concerns the robustness of attitude controllers for dynamics configured on the SO(3) manifold and poses a set of bilinear matrix inequalities to find an optimal controller tuning with respect to (i) the ultimate bound of the error-state trajectories when perturbed by naturally arising disturbances, and (ii) the worst-case decay rate of the tracking errors. The presented optimization pro

A search for the decays of stopped long-lived particles at √s = 13 TeV with the ATLAS detector

A search for long-lived particles, which have come to rest within the ATLAS detector, is presented. The subsequent decays of these particles can produce high-momentum jets, resulting in large out-of-time energy deposits in the ATLAS calorimeters. These de- cays are detected using data collected during periods in the LHC bunch structure when collisions are absent. The analysed dataset is composed o

Search for supersymmetry in events with four or more charged leptons in 139 fb−1 of √s = 13 TeV pp collisions with the ATLAS detector

A search for supersymmetry in events with four or more charged leptons (electrons, muons and τ-leptons) is presented. The analysis uses a data sample corresponding to 139 fb−1 of proton-proton collisions delivered by the Large Hadron Collider at s = 13 TeV and recorded by the ATLAS detector. Four-lepton signal regions with up to two hadronically decaying τ-leptons are designed to target several su

Predicting future stability of ecosystem functioning under climate change

To maintain food security under global change, we need to consider the stability of ecosystem functioning into the future, particularly in resource production landscapes such as agricultural pasture. With ongoing climate change, extreme climatic events are predicted to become more frequent and severe globally, impacting crop production. The whole process of farming will become more uncertain, from

In situ passivation of GaxIn(1−x)P nanowires using radial AlyIn(1−y)P shells grown by MOVPE

GaxIn(1−x)P nanowires with suitable bandgap (1.35-2.26 eV) ranging from the visible to near-infrared wavelength have great potential in optoelectronic applications. Due to the large surface-to-volume ratio of nanowires, the surface states become a pronounced factor affecting device performance. In this work, we performed a systematic study of GaxIn(1−x)P nanowires' surface passivation, utilizing A

Nonhydrolysable Analogues of (p)ppGpp and (p)ppApp Alarmone Nucleotides as Novel Molecular Tools

While alarmone nucleotides guanosine-3',5'-bisdiphosphate (ppGpp) and guanosine-5'-triphosphate-3'-diphosphate (pppGpp) are archetypical bacterial second messengers, their adenosine analogues ppApp (adenosine-3',5'-bisdiphosphate) and pppApp (adenosine-5'-triphosphate-3'-diphosphate) are toxic effectors that abrogate bacterial growth. The alarmones are both synthesized and degraded by the members

How did micro-mobility change in response to COVID-19 pandemic? : A case study based on spatial-temporal-semantic analytics

Cities worldwide adopted lockdown policies in response to the outbreak of coronavirus disease 2019 (COVID-19), significantly influencing people's travel behavior. In particular, micro-mobility, an emerging mode of urban transport, is profoundly shaped by this crisis. However, there is limited research devoted to understanding the rapidly evolving trip patterns of micro-mobility in response to COVI

Is it a revolution or a coup? : Scandinavian media representations of the ousting of Egyptian President Mohamed Morsy

In the summer of 2013, millions of Egyptians returned to Tahrir square in Cairo to demand the resignation of the country’s first democratically elected president. This article examines the two key terms mainly used to describe the ousting of President Mohamed Morsy, ‘coup’ and ‘revolution’, and how these terms can be understood as arguments for two different interpretations of the event. Particula

Improvement of structural efficiency in metals by the control of topological arrangements in ultrafine and coarse grains

Improvement of structural efficiency in various materials is critically important for sustainable society development and the efficient use of natural resources. Recently, a lot of attention in science and engineering has been attracted to heterogeneous-structure materials because of high structural efficiency. However, strategies for the efficient design of heterogenous structures are still in th

Professionals’ expectations and preparedness to implement knowledge-based palliative care at nursing homes before an educational intervention : A focus group interview study

The provision of knowledge-based palliative care is rare in nursing homes. There are obstacles to practically performing this because it can be difficult to identify when the final stage of life begins for older persons. Educational interventions in palliative care in nursing homes are a challenge, and joint efforts are needed in an organisation, including preparedness. The aim was to explore prof

Gender and the Outcome of Postcardiotomy Veno-arterial Extracorporeal Membrane Oxygenation

Objective: There is a paucity of sex-specific data on patients’ postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO). The present study sought to assess this issue in a multicenter study. Design: Retrospective, propensity score–matched analysis of an international registry. Setting: Multicenter study, tertiary university hospitals. Participants: Data on adult patients undergoi

Tailoring plasmonic resonances in Cu-Ag metal islands films

The plasmonic response of Cu-Ag metal islands films is investigated. Films are obtained by subsequent electron beam deposition of Ag and Cu using different fabrication conditions: deposited mass thickness, substrate temperature and post-deposition annealing in vacuum. Optical properties of films are investigated by spectroscopic ellipsometry and correlated with the structural characterization resu

Decoding mechanical cues by molecular mechanotransduction

Cells are exposed to a variety of mechanical cues, including forces from their local environment and physical properties of the tissue. These mechanical cues regulate a vast number of cellular processes, relying on a repertoire of mechanosensors that transduce forces into biochemical pathways through mechanotransduction. Forces can act on different parts of the cell, carry information regarding ma
