This paper analyzes the problem and requirements of securely distributing software updates over the Internet,to devices in an Industrial Control System (ICS) and more generally in Internet of Things (IoT) infrastructurescontrolling a physical system, such as power grids and water supply systems. We present a novel approachthat allows to securely distribute software updates of different types, e.g.
In this short note we observe that within the family of slowly recurrent rational maps on the Riemann sphere, the Collet–Eckmann, second Collet–Eckmann, and topological Collet–Eckmann conditions are equivalent and also invariant under topological conjugacy.
Many allergens are widely used in both consumer and occupational products. In many cases, it is difficult to know all the ingredients of a product since most products are not sufficiently labelled. To diagnose and prevent allergic contact dermatitis, the demonstration of allergens in the products from the patient’s environment is important. Chemical analysis of a product can make it possible to de
Lake Urmia, located in northwestern Iran, is the largest salt lake in the Middle East (ME) and one of the largest hypersaline lakes in the world. The lake has an important role in biodiversity preservation and the economic and cultural aspects of its surrounding region. Over the last two decades, the combined effects of climate change and anthropogenic activities have caused a significant depletio
Epilepsy is one of the most common neurological disorders that is characterized by recurrent and unpredictable seizures. Wearable systems can be used to detect the onset of a seizure and notify family members and emergency units for rescue. The majority of state-of-the-art studies in the epilepsy domain currently explore modern machine learning techniques, e.g., deep neural networks, to accurately
The advent of deep learning has yielded powerful tools to automatically compute gradients of computations. This is because training a neural network equates to iteratively updating its parameters using gradient descent to find the minimum of a loss function. Deep learning is then a subset of a broader paradigm; a workflow with free parameters that is end-to-end optimisable, provided one can keep t
Multiple concepts for future generations of wireless communication standards utilize coherent processing of signals from many distributed antennas. Names for these concepts include distributed MIMO, cell-free massive MIMO, XL-MIMO, and large intelligent surfaces. They aim to improve communica- tion reliability, capacity, as well as energy efficiency and provide possibilities for new applications t
Prydlig, proper och välskött - så tycks den perfekta trädgården se ut. Men när den kortklippta gräsmattan växte fram som ideal bland Europas välbärgade var övriga naturen vildare. I en tid av artutrotning och klimatförändringar finns det större behov än någonsin av otjämjda trädgårdar, skrive råtta forskare och landskapsarkitekter.In an era of species extinction and climate change, we should abandon the well-trimmed lawn and let gardens grow wilder, writes Anna Persson and other researchers and landscape architects on DN Debatt.
BACKGROUND: eHealth applications are considered a technological fix that can potentially address some of the grand challenges in healthcare, including burnout among healthcare professionals, the growing burden of patients with chronic conditions, and retaining and recruiting healthcare professionals. However, as the deployment of eHealth applications in healthcare is relatively novel, there is a l
The beamlines at CERN's North and East Areas offer secondary beams in a wide range of momenta between 0.5 GeV/c and 400 GeV/c for fixed-target experiments as well as for test beam campaigns with a flexible configuration and variable beam composition and intensities. Recently, two new facilities for neutrino detectors tests have been established in an extension of the CERN North Area in context of
BackgroundDuring recent years FLASH radiotherapy (FLASH-RT) has shown promising results in radiation oncology, with the potential to spare normal tissue while maintaining the antitumor effects. The high speed of the FLASH-RT delivery increases the need for fast and precise motion monitoring to avoid underdosing the target. Surface guided radiotherapy (SGRT) uses surface imaging (SI) to render a 3D
The recent emergence of deep learning and computer vision-based 3D human pose estimation presents opportunities for a form of markerless motion-capture. State-of-the-art approaches have achieved remarkable accuracy in predicting global and relative joint positions, however, many potential applications require information on joint orientations, e.g., in the fields of biomechanics. Furthermore, me
Lead halide perovskites (LHPs) photoelectrodes for photoelectrochemical (PEC) water splitting are promising candidates for solar-to-fuel conversion. However, the poor stability of LHPs in aqueous electrolyte media, together with the toxicity of lead, restricts the practical application of LHP photoelectrodes. Herein, we report the first-ever colloidal synthesis of quaternary Cu1.4Ag0.6BiI5 nanocry
Carefully selecting the right collection datastructure can significantly improve the performance of a Java program. Unfortunately, the performance impact of a certain collection selection can be hard to estimate.To assist developers there are tools that recommend collections to use based on static and/or dynamic information about a program. The majority of existing collection selection tools for J
Asylum-seekers, like any population, need healthcare services, yet national laws sometimes restrict access to such services. The European Social Charter (revised) protects the right to health and medical services. However, the Charter has a complex application, and its scope is limited concerning foreigners. This article analyses to what extent the provisions of the Charter on the right to health
Regeringen tillsatte med anledning av EG-direktiv 2001/83 en arbetsgrupp för att utreda hur framtidens läkemedelsreklam ska organiseras. Målet är att bidra till en säker och effektiv läkemedelsanvändning i Sverige. Mot bakgrund av en analys av EG-direktivet, utländska förebilder, svensk grundlag och i Sverige gällande marknadsföringsbestämmelser i läkemedelslagen (1992:859) och marknadsföringslage
