Quantitative assessment of impedance tomography for temperature measurements in hyperthermia
The objective of this study is a non-invasive assessment of the thermal dose in hyperthermia. Electrical impedance tomography (EIT) has previously been given a first trial as a temperature monitoring method together with microwave-induced hyperthermia treatment, but it has not been thoroughly investigated. In the present work we have examined this method in order to investigate the correlation in
Improvements in The Hardware of The Lund Impedance Tomography System
The objective of this study is to improve the quality of the hardware of the existing Lund impedance tomography system. Improvement in the current generator and different isolation proposals are presented.
A method for MR quantification of flow velocities in blood and CSF using interleaved gradient-echo pulse sequences
The aim of this study was to establish a rapid method for in vivo quantification of a large range of flow velocities using phase information. A basic gradient-echo sequence was constructed, in which flow was encoded along the slice selection direction by variation of the amplitude of a bipolar gradient without changes in sequence timings. The influence of field inhomogeneities and eddy currents wa

A Light Signalling Approach to Node Grouping for Massive MIMO IoT Networks
Massive MIMO is a promising technology to connect very large numbers of energy constrained nodes, as it offers both extensive spatial multiplexing and large array gain. A challenge resides in partitioning the many nodes in groups that can communicate simultaneously such that the mutual interference is minimized. We here propose node partitioning strategies that do not require full channel state in
A descriptive study of pain treatment and its follow-up in primary care of elderly patients after orthopaedic care
Background: Pain treatment post orthopaedic care in the elderly is complicated and requires careful follow-up. Current guidelines state all patients prescribed opioids should have a plan for gradual reduction, with the treatment progressively reduced and ended if any pain remains after more than three months. How this works in primary care remains to be explored.The aim was to describe pain treatm

The role of the understory in litter DOC and nutrient leaching in boreal forests
Dissolved organic carbon (DOC) derived from plant litter plays an important role in the ecosystem carbon balance and soil biogeochemistry. However, in boreal coniferous forests no integrated understanding exists of how understory vegetation contributes to litter leaching of DOC, nitrogen (N) and phosphorus (P) with different bioavailability at the forest stand level. We characterized water extract
Applicability of ultrasonic tomographic technique for progressive damage evaluation in prismatic rock specimen
Several damage processes are associated with the loading of intact rock specimens including closure of existing microcracks, initiation of cracks, and finally development of cracks. Ultrasonic imaging techniques have proven to be very successful in providing relatively high-resolution images of the damage processes in the rock. Ultrasonic velocity tomography is a full-field measurement technique t

Remarkable preservation of microfossils and biofilms in mesoproterozoic silicified bitumen concretions from Northern China
Prokaryotes, often generally referred to as “bacteria,” are the original and thus oldest life on Earth. They have shaped the chemical environment of the Earth, but they are difficult to find as ancient fossils due to their subtle structure. Here we report well-preserved fossilized microbial communities in silicified bitumen concretions from unit 3 of the Xiamaling Formation (1.39 Ga) in northern C
Oxygen, climate and the chemical evolution of a 1400 million year old tropical marine setting
The Xiamaling Formation is an exceptionally well-preserved sedimentary succession deposited on a marine passive margin about 1400 million years ago. We used a multi-proxy approach, including iron speciation, trace metal dynamics, and organic geochemistry, to explore the evolution of ocean chemistry through most of the Xiamaling Formation. This evolution is put in the context of the paleogeography
Convergent Evolution, Evolving Evolvability, and the Origins of Lethal Cancer
Advances in curative treatment to remove the primary tumor have increased survival of localized cancers for most solid tumor types, yet cancers that have spread are typically incurable and account for >90% of cancer-related deaths. Metastatic disease remains incurable because, somehow, tumors evolve resistance to all known compounds, including therapies. In all of these incurable patients, de novo
Brief Report : Interferon-γ-Inducible Protein 10-A Potential Marker for Targeted Viral Load Monitoring of Antiretroviral Treatment?
BACKGROUND: The use of surrogate markers for targeting viral load (VL) testing could be an alternative to universal VL testing during antiretroviral treatment (ART) and would allow for more effective resource allocation. We investigated the correlation between levels of HIV RNA and interferon-γ-inducible protein 10 (IP-10) in Ethiopian adults at 12 months after ART initiation. In addition, we spec
