Both intelligence operatives and criminals have a constant need to be able to communicate clandestinely, circumventing surveillance efforts carried out by highly capable adversaries. The recent highly-publicized breaches of internet-based clandestine communications technology and targeted malware attacks, in combination with increasingly sophisticated methods for surveillance of internet traffic h

The Earth’s magnetic field (or geomagnetic field) has been measured for hundreds of years, starting with maritime observations from logbooks for navigation purposes to present day real-time recording by satellites. From these records, the geomagnetic field variation throughout recent time is well-understood. In order to study longer term field variations (on the scale of hundreds to thousands of y

Alterations of the sense of self induced by meditation include an increased sense of boundarylessness. In this study, we investigatedbehavioural and functional magnetic resonance imaging correlates of trait self-boundarylessness during resting state and the performanceof two experimental tasks. We found that boundarylessness correlated with greater self-endorsement of words related to fluidityand

IntroductionNine in ten of the world’s 1.74 million adolescents living with human immunodeficiency virus (ALHIV) live in Sub-Saharan Africa. Suboptimal adherence to antiretroviral therapy (ART) and poor viral suppression are important problems among adolescents. To guide intervention efforts in this regard, this review presented pooled estimates on the prevalence of adherence and how it is affecte

As the dream of autonomous vehicles moving around in our world comes closer, the problem of robust localization and mapping is essential to solve. In this inherently structured and geometric problem we also want the agents to learn from experience in a data driven fashion. How the modern Neural Network models can be combined with Structure from Motion (SfM) is an interesting research question and As the dream of autonomous vehicles moving around in our world comes closer, the problem of robust localization and mapping is essential to solve.

The differential cross section of inelastic electron scattering for the low-lying “collective” Kπ=1+ excitations in rare-earth nuclei is calculated in DWBA by using microscopically calculated transition-densities. In the region of low-momentum transfer (q⪅0.5 fm-1) in which experimental data are available the shape of calcualted cross sections is almost the same for all nuclei and is slightly but

The influence of a quadrupole pair interaction on Kπ = 1+ states in rare earth nuclei is investigated using the Quasiparticle Random Phase Approximation. Comparison of the obtained results with available experimental data indicates a rather weak quadrupole pair interaction in these nuclei. The calculation of the B(M1) strength is extended to higher energies to account for the recently observed hig

We show: (1) In the presence of the pair correlation the M1 transition strength calculated in the deformed oscillator model has a dependence on the quadrupole deformation parameter δ which is considerably stronger than linear and, in fact, it varies quadratically with δ in the limit of small deformation; (2) The deformation dependence in samarium isotopes calculated using the quasiparticle random

The problem of estimating the node density in ad hoc networks is a significant one for protocol design. In molecular nanonetworks, the node density estimation problem poses additional challenges due to the limited processing and communication capabilities of the network nodes which necessitate the design of simple to implement distributed solutions, and the diffusion based communication channel wh

Research is needed to understand attitudes toward and adoption of the broad range of technologies available to support active and healthy aging in different generations. The present article gives an overview of the GenerationTech survey and sample, and describes attitudes and acceptance related to technology in general and as a means to support active and healthy aging. A national survey was condu

När ett barn föds är det mycket i samhället som det ännu inte har träffat på. Ja, faktiskt det mesta. Vem barnet blir och vilka vägar det väljer genom livet kommer att påverkas av många faktorer, däribland utformningen av alla de produkter och miljöer det över tid möter och interagerar med. I detta kapitel ägnar vi oss åt fysiska aspekter av interaktionen mellan individ och samhälle, med fokus på

HyperSurfaces (HSFs) comprise structurally reconfigurable metasurfaces whose electromagnetic properties can be changed via a software interface, using an embed- ded miniaturized network of controllers, enabling novel capabilities in wireless communications, including 5G applications. Resource constraints associated with a hardware testbed of this breakthrough technology, currently under developmen

Computer-vision-based gaze estimation refers to techniques that estimate gaze direction directly from video recordings of the eyes or face without the need for an eye tracker. Although many such methods exist, their validation is often found in the technical literature (e.g., computer science conference papers). We aimed to (1) identify which computer-vision-based gaze estimation methods are usabl

Alexander Paulsson, Henrik Rahm, Niklas Sandell och Peter Svensson harstuderat bolagsstämman som ett kulturfenomen. Denna artikel bygger påden nyligen publicerade boken ”Bolagsstämman – ritualer, kultur, normeroch språk” i vilken börsnoterade företags bolagsstämmor tolkas sombetydelsefulla ekonomiska ritualer.

In the academic discussion about the Muslim Brotherhood, MB in Sweden, there is consensus that the Islamic Association in Sweden, IFiS is inspired by MB but the organizational relationship between the organizations has not been researched before. Holy White Lies is an English translation of the original Arabic book al-Kedhb al-Abyad al-Muqaddas. Both books were published in Cairo 2018. The book co

Det renade avloppsvattnet från en anläggning med en membranbioreaktor och granulerat aktivt kol nådde kraven för färdigt dricksvatten för metaller, men inte för bakterier. Vattnet bedömdes ha tillräcklig kvalitet för bevattning och som råvatten för dricksvattenberedning. Koncentrationerna av mikroföroreningar var i samma storleksordning som i svenska dricksvattentäkter, och därmed i nivå med vad vThe treated wastewater from a full scale MBR and GAC reached drinking water quality regarding metals, but not bacteria. The water quality is however assessed as sufficient for irrigation or as a source water for drinking water production, based on the parameters analyzed in the project. The concentrations of organic micro pollutants were similar to the ones measured in Swedish drinking water sourc

Genetic variation at the MTIF3 (Mitochondrial Translational Initiation Factor 3) locus has been robustly associated with obesity in humans, but the functional basis behind this association is not known. Here, we applied luciferase reporter assay to map potential functional variants in the haplotype block tagged by rs1885988 and used CRISPR-Cas9 to edit the potential functional variants to confirm
