Reinforcement Learning for Active Visual Perception

Visual perception refers to automatically recognizing, detecting, or otherwise sensing the content of an image, video or scene. The most common contemporary approach to tackle a visual perception task is by training a deep neural network on a pre-existing dataset which provides examples of task success and failure, respectively. Despite remarkable recent progress across a wide range of vision task

Atomic-Scale Observation of Oxygen Vacancy-Induced Step Reconstruction in WO3

As the most common type of defects in WO3, surface oxygen deficiencies have been widely investigated in terms of their structure as well as physicochemical properties. In general, oxygen vacancy on the surface may lead to the reconstruction of the surface structure due to the need for surface energy minimization, especially for the area with high oxygen vacancy concentration. However, such a pheno

Impact of spacing of ultrasound receiving beams on estimation of 2D motion velocity

For more detailed measurement of cardiovascular motion and complex blood flow, a two-dimensional (2D) velocity estimation method is required in functional ultrasound imaging. The block matching method based on the correlation function is one of the standard 2D motion estimators. In this study, we investigated the effect of lateral sampling intervals of an ultrasonic B-mode image on the accuracy in

Local Autonomy in Temporary Organizations : The Case of Smart City Pilots

Local actors are to an increasing extent engaging in national and European Union (EU)–based development and sustainability agendas. These ventures often materialize in the form of temporary organizations such as pilots and projects. This article contributes to debates on project-based, experimental and temporary organizations by unpacking the organizational architecture of pilots and analyzing how

Swedish guidelines for device-aided therapies in Parkinson's disease —Economic evaluation and implementation

Objectives: The National Board of Health and Welfare in Sweden published the national guidelines for Parkinson's Disease 2016. The aim of this study was to summarize this evidence review and development of the guidelines, focusing on the economic evaluation of device-aided therapies (deep brain stimulation, pump-based infusion of levodopa-carbidopa intestinal gel or apomorphine) for Parkinson's di

Hg(II) Binding to Thymine Bases in DNA

The compounds of mercury can be highly toxic and can interfere with a range of biological processes, although many aspects of the mechanism of toxicity are still obscure or unknown. One especially intriguing property of Hg(II) is its ability to bind DNA directly, making interstrand cross-links between thymine nucleobases in AT-rich sequences. We have used a combination of small molecule X-ray diff

Outdoor Office Work – An Interactive Research Project Showing the Way Out

The physical boundaries of office work have become increasingly flexible. Work is conducted at multiple locations outside the office, such as at clients’ premises, at home, in cafés, or when traveling. However, the boundary between indoor and outdoor environment seems to be strong and normative regarding how office work is performed. The aim of this study was to explore how office work may be cond

Laminar burning velocity measurements of ethanol+air and methanol+air flames at atmospheric and elevated pressures using a new Heat Flux setup

A new setup for burning velocity measurements of liquid fuels at elevated pressures using the Heat Flux method has been constructed. The burner design has been improved comparing to previous studies in this and other laboratories. Laminar burning velocities were determined experimentally for ethanol+air and methanol+air mixtures over a range of conditions including equivalence ratio (0.8 to 1.3),

Evaluating competition for forage plants between honey bees and wild bees in Denmark

A recurrent concern in nature conservation is the potential competition for forage plants between wild bees and managed honey bees. Specifically, that the highly sophisticated system of recruitment and large perennial colonies of honey bees quickly exhaust forage resources leading to the local extirpation of wild bees. However, different species of bees show different preferences for forage plants

Women in violent extremism in Sweden

The report analyses women in violent extremism based on contemporary data for Sweden. Statistics are presented across various demographic and criminal indicators for violent far-left, far-right and Islamic extremistm, compared to same-sex siblings, to men in the same violent extremist milieus and to women in other antagonistic milieus. There are both similarities and differences between groups. Wo

Enabling Reuse in Extended Producer Responsibility Schemes for White Goods : Legal and Organisational Conditions for Connecting Resource Flows and Actors

Extended producer responsibility (EPR) schemes have proliferated across Europe and other parts of the world in recent years and have contributed to increasing material and energy recovery from waste streams. Currently, EPR schemes do not provide sufficient incentives for moving towards the higher levels of the waste hierarchy, e.g. by reducing the amounts of waste through incentivising the design

Modelling and Simulation of the Fifth-Generation District Heating and Cooling

Fjärrvärme och fjärrkyla är ändamålsenliga system för distribution av värme och kyla i tätbebyggda områden. Dessa system är viktiga vid planeringen av framtida energieffektiva system på grund av deras höga potential för att integrera förnybara energikällor. Systemen spelar också en viktig roll i samhällets energiförsörjningssäkerhet, vilket gör dem till ett tvärvetenskapligt forskningsområde. Den District heating and cooling are efficient systems for distributing heat and cold in urban areas. They are a key solution for planning future urban energy-efficient systems due to their high potential for integrating renewable energy sources. The systems also play an important role in community resilience, which makes them a multidisciplinary research topic. The continuous development of these sys

Spectral Analysis of Lithium Tremor

Introduction: Lithium has proven efficacy in bipolar affective disorder (BAD) but induces tremor as a side effect in a quarter of patients. Lithium tremor (LT) shares some clinical characteristics of essential tremor (ET) and Parkinson’s disease tremor (PT), which might cause difficulties in differential diagnosis. Furthermore, current knowledge of LT is lacking detailed electrophysiological chara

OBJECTIVE: To evaluate compliance to workflow and accuracy of tests in Sweden's first fast-track referral pathway for patients with nonspecific symptoms and suspected cancer (SCAN).DESIGN: Prospective cohort study with consecutive inclusion of patients referred to the diagnostic center (DC).SETTING: Patients with nonspecific symptoms were examined in primary care according to a protocol including

Digital Corporate Communication and Internal Communication

Internal communication is becoming increasingly digital. This chapter deals with how digital internal communication can be understood and discusses the implications of the digitalization of internal communication for organizations and organizing. It reviews previous definitions of internal communication and digitalization and proposes a definition of digital internal communication. It reviews prev

Coupling Microplate-Based Antibacterial Assay with Liquid Chromatography for High-Resolution Growth Inhibition Profiling of Crude Extracts : Validation and Proof-of-Concept Study with Staphylococcus aureus

With the identification of novel antibiotics from nature being pivotal in the fight against human pathogenic bacteria, there is an urgent need for effective methodologies for expedited screening of crude extracts. Here we report the development and validation of a simple and dye-free antimicrobial assay in 96-well microplate format, for both determination of IC50 values and high-resolution inhibit
