Pairwise comparison of sound and radio signals can be used to estimate the distance between two units that send and receive signals. In a similar way it is possible to estimate differences of distances by correlating two received signals. There are essentially two groups of such methods, namely methods that are robust to noise and reverberation, but give limited precision and sub-sample refinement

Recent progress in stem cell biology and epigenetic reprogramming has opened up previously unimaginable possibilities to study and develop regenerative approaches for neurological disorders. Human neurons and glial cells can be generated by differentiation of embryonic and neural stem cells and from somatic cells through reprogramming to pluripotency (followed by differentiation) as well as by dir

An inferior dermal flap (“sling”) can be used to cover an implant with two layers of tissue following Wise pattern skin-reducing mastectomies. Here, we performed a systematic review of the risks and benefits of this technique, specifically regarding complications, patient-reported outcomes, and aesthetic outcomes. PubMed and other relevant databases were searched using specific key words, with inc

Aim: To describe the detailed health-related quality of life (HRQoL) in survivors from the TTM-trial and to investigate potential differences related to sex and age. Methods: This is a cross-sectional study originating from a large prospective international, multicentre trial, including 442 respondents who answered the Short Form-36 item Questionnaire Health Survey version 2® (SF-36v2®) at a struc

The work at hand is a selection of topics in efficient wireless communication system design, with topics logically divided into two groups.One group can be described as hardware designs conscious of their possibilities and limitations. In other words, it is about hardware that chooses its configuration and properties depending on the performance that needs to be delivered and the influence of exte

Growing GaAs nanowires with well-defined crystal structures is a challenging task, but may be required for the fabrication of future devices. In terms of crystal phase selection, the connection between theory and experiment is limited, leaving experimentalists with a trial and error approach to achieve the desired crystal structures. In this work, we present a modeling approach designed to provide

We reconsider the Generalized Kadanoff–Baym Ansatz (GKBA) approximation for non-equilibrium Green’s functions and extend it to self-consistently define an equilibrium correlated (within GKBA) state in closed systems. The advantage of the proposed prescription is to avoid the preparation of the initial equilibrium correlated state via adiabatic switching-on of the correlations. A simple model syste

Around two thirds of all refugees are stuck in their refugee situations for a long time, and many refugees are confined to isolated camps and provided the bare minimum in kind. This article examines the effects of a pilot cash-based transfer (CBT) program in Nyarugusu Refugee Camp, one such place of protracted displacement. The article shows that CBT is promising for many reasons; however, it also

When primary tumor cells are grown in vitro, they are exposed to an environment that is vastly different from the tumor environment they originate from. The in vitro environment can lack the three-dimensional structure of the tumor, other cell types present within the tumor microenvironment, and important growth factors. Humanized mouse models allow researchers to study primary tumor cells in a mo

Purpose: Reliable data on familial risks are important for clinical counseling and cancer genetics. However, population-based studies on familial soft tissue tumors are limited, which we will examine. Methods: Adjusted standardized incidence ratios (SIRs), calculated from the nation-wide Swedish Family Cancer Database, were used to measure the familial risk. Results: There were 17 offspring-parent

Objective: To explore the subjective experience of living with dementia with Lewy bodies (DLB). Design A qualitative study of in-depth interviews using interpretative phenomenological analysis. Setting: A memory clinic in Malmö, southern Sweden. Participants: A purposive sample of five male participants with DLB between the ages of 78 and 88 years and disease duration of 1.5-7 years.

Background: Improved survival for breast cancer is increasing the likelihood of contralateral tumors. Mammographic screening is partially contributing to the survival advantage, while changing many aspects of breast cancer presentation, including age at diagnosis, histology and familial risk. As mammography has become widely used, it is important to quantify the risks for contralateral breast canc

Background: Population-based data on the familial risk for vascular tumors are largely lacking. Such data are important for clinical counseling and cancer genetics. Methods: We used the Swedish Family-Cancer Database to calculate standardized incidence ratios for specific subtypes of vascular tumors in offspring using parents as probands. In addition, risks for second cancers were analyzed. Result

Reliable data on familial risks are important for clinical counselling and cancer genetics. However, the estimates of familial risk of gastric cancer vary widely. We examined the risk of familial gastric cancer using the updated Swedish Family-Cancer Database with 5358 patients among offspring and 36 486 patients among parents. There were 133 families with one parent and one offspring diagnosed wi

Water shortages across the globe have increased due to climate change among other factors with negative impacts expected at the river basin level. Anticipating these impacts will help experts act in a timely manner to avoid a future water crisis. As part of addressing the future water shortage impacts on the Togolese community, this paper assessed water security in the context of the global enviro

This study evaluated factors underlying individual differencesin spontaneous (unsuggested) experiences during hypnosis.Participants varying in hypnotizability (low, medium, and high) completeda questionnaire about various dimensions of consciousness theywould expect to experience at the “deepest level of hypnosis” (expectancy),an eyes-closed resting condition (baseline), and their actualexperience
