Towards Conceptualizing and Modelling Critical Flows - A Three-Tier Modelling Framework with a Swedish Example

Continuous access to flows of goods and services, such as energy, transport, information, and food, is essential and the basis for functioning modern societies. Hence, they are critical and need to be secured. Mega-trends such as climate change, changing geopolitical environment, hybrid- and cyber threats, and rapid technological advances come with new challenges and emerging threats to securing f

The TESS-Keck Survey. XI. Mass Measurements for Four Transiting Sub-Neptunes Orbiting K Dwarf TOI-1246

Multiplanet systems are valuable arenas for investigating exoplanet architectures and comparing planetary siblings. TOI-1246 is one such system, with a moderately bright K dwarf (V = 11.6, K = 9.9) and four transiting sub-Neptunes identified by TESS with orbital periods of 4.31, 5.90, 18.66, and 37.92 days. We collected 130 radial velocity observations with Keck/HIRES and TNG/HARPS-N to measure pl

QUENCHED LIMIT THEOREMS FOR RANDOM U(1) EXTENSIONS OF EXPANDING MAPS

In this paper we provide quenched central limit theorems, large deviation principles and local central limit theorems for random U(1) extensions of expanding maps on the torus. The results are obtained as special cases of corresponding theorems that we establish for abstract random dynamical systems. We do so by extending a recent spectral approach developed for quenched limit theorems for expandi

Risk bounded nonlinear robot motion planning with integrated perception & control

Robust autonomy stacks require tight integration of perception, motion planning, and control layers, but these layers often inadequately incorporate inherent perception and prediction uncertainties, either ignoring them altogether or making questionable assumptions of Gaussianity. Robots with nonlinear dynamics and complex sensing modalities operating in an uncertain environment demand more carefu

Global Legitimacy Crises : Decline and Revival in Multilateral Governance

Presents new conceptualization of legitimacy crises in global governanceOffers new theoretical ideas on legitimacy crises as activation that can yield positive as well as negative consequencesProvides a comparative assessment of legitimacy crises and their consequences in 32 international organizations and across three decadesDevelops in-depth insights on the legitimacy crises of the WTO and the U

Visuospatial ability is associated to 2D laparoscopic simulator performance amongst surgical residents

Background: The technical skills of a surgeon influence surgical outcome. Testing technical aptitude at point of recruitment of surgical residents is only conducted in a few countries. This study investigated the impact of visuospatial ability (VSA), background factors, and manual dexterity on performance in two different laparoscopic surgical simulators amongst applicants and 1st year surgical re

A matter of timing : System requirements for repair and their temporal dimensions

Research into repair within the circular economy (CE) typically focuses on technical aspects of design, policy, and markets, and often assumes simplified conditions for the user/owner and the product system to explain the barriers to scaling repair activities. However, factors occurring at pre-use stages of the product's life cycle can significantly influence whether, and to what extent, repair is

Engagement

This chapter examines how the Iraq War shook public confidence in government communications, and the impact of the Phillis Review upon public diplomacy theory and practice. It covers the Carter Review, which assessed levels of accountability in public diplomacy expenditure, and advised the creation of a new oversight board, the Public Diplomacy Board; efforts to make public and digital diplomacy p

Conclusion : The Quest for Gender Justice in Diplomacy

In this last chapter, a series of more general propositions about contemporary gender and diplomacy are identified from the contributions to this book. First, it provides a historical narrative on the exclusions and inclusions in diplomacy over time, suggesting the contours of general trends in the quest to end formal barriers and bring about gender parity. Second, it critically analyses the gende

In situ quantitative analysis of electrochemical oxide film development on metal surfaces using ambient pressure X-ray photoelectron spectroscopy : Industrial alloys

Ambient Pressure X-ray Photoelectron Spectroscopy combined with an electrochemical setup is used to study, in situ, the electrochemical oxide growth on an industrial Ni-Cr-Mo alloy. The native oxide film was characterized in vacuum and in water vapor at 17 mbar, and was found to be 11.4 Å thick and rich in Cr3+. In 0.1 M NaCl electrolyte, anodic growth of the oxide film at potentials up to 700 mV

Neuronal activity patterns in microcircuits of the cerebellar cortical C3 zone during reaching

Abstract: The cerebellum is the largest sensorimotor structure in the brain. A fundamental organizational feature of its cortex is its division into a series of rostrocaudally elongated zones. These are defined by their inputs from specific parts of the inferior olive and Purkinje cell output to specific cerebellar and vestibular nuclei. However, little is known about how patterns of neuronal acti

A business model pattern arrives … and then? A translation perspective on business model innovation in established firms

This study examines business model innovation in an established firm. We investigate the case of a Swedish utility company that adopted and implemented a business model pattern originating from outside the firm. We draw upon Scandinavian translation theory to understand the micro-level dynamics of how business model innovation unfolds. Our findings show that the business model pattern is disassemb

A study of neural activity and functional connectivity within the olfactory brain network in Parkinson's disease

Olfactory dysfunction is an early manifestation of Parkinson's disease (PD). The present study aimed to illustrate potential differences between PD patients and healthy controls in terms of neural activity and functional connectivity within the olfactory brain network. Twenty PD patients and twenty healthy controls were examined with olfactory fMRI and resting-state fMRI. Data analysis of olfactor

Mapping trait versus species turnover reveals spatiotemporal variation in functional redundancy and network robustness in a plant-pollinator community

Functional overlap among species (redundancy) is considered important in shaping competitive and mutualistic interactions that determine how communities respond to environmental change. Most studies view functional redundancy as static, yet traits within species—which ultimately shape functional redundancy—can vary over seasonal or spatial gradients. We therefore have limited understanding of how

Factors influencing self-management behavior during the “Blanking Period” in patients with atrial fibrillation : A cross-sectional study based on the information-motivation-behavioral skills model

Background: Atrial fibrillation (AF) is becoming increasingly common. Effective self-management during the “Blanking Period” is critical. The Information-Motivation-Behavioral skills (IMB) model can be used to study health behaviors in chronic disease patients, but it has not been studied in AF patients. Objective: The goal of this study was to explore the influencing factors and interaction pathw

A 50 µm acoustic resonator microchannel enables focusing 100 nm polystyrene beads and sub-micron bioparticles

The manipulation and focusing of submicron/nanometre-scale objects are becoming increasingly important in the fields of biology, chemistry, and materials science. Acoustofluidics provides for the high throughput and precise manipulation of cells and particles with simple equipment. However, application to submicron/nanoparticles is challenging due to the particle volume dependence of the acoustic
