Scanning acoustic microscopy (SAM) is a non-ionizing and label-free imaging modality used to visualize the surface and internal structures of industrial objects and biological specimens. The image of the sample under investigation is created using high-frequency acoustic waves. The frequency of the excitation signals, the signal-to-noise ratio, and the pixel size all play a role in acoustic image ...

Introduction - As the knowledge base evolves in research and clinical application, the demands for adaptability and development in the acupuncture community increase. This study investigates whether acupuncturists in Norway implement changes in their practice according to the developments in research, and which sources of information they use to inform their practice.<p> <p>Methods - Between June ...

Recently, Rozelot & Eren pointed out that the first solar gravitational moment (J₂) might exhibit a temporal variation. The suggested explanation is through the temporal variation of the solar rotation with latitude. This issue is deeper developed due to an accurate knowledge of the long-term variations in solar differential rotation regarding solar activity. Here we analyze solar cycles ...

Cultivation of sterile-only fish in aquaculture offers multiple benefits of environmental, economical, and social value. A reliable method for efficient sterilization without affecting fish welfare and performance traits would have significant impact on fish production practices. Here, we demonstrate sterilization of Atlantic salmon embryos by targeting the dead end gene with antisense oligonucleotides. ...

Objectives To compare results of selected performance measures in mammographic screening for an artifcial intelligence (AI) system versus independent double reading by radiologists.<p> <p>Methods In this retrospective study, we analyzed data from 949 screen-detected breast cancers, 305 interval cancers, and 13,646 negative examinations performed in BreastScreen Norway during the period from 2010 ...

In this study, we look at the decision to provide services following a child protection investigation in Norway. More specifically, we want to look at variability at the case level and at the agency level in order to identify factors that may impact a decision to provide services. The study was designed as a cross-sectional archive study that was carried out retrospectively. Included predictors ...

This article explored experiences of ageing from interviews with a sample drawn from a population living in a North Sami community. Our focus is on older adult’s involvement in activities that emphasise and maintain them as participants in specific kinds of activities that require knowledge, skills and mentorship, and to what degree it provides them with social capital and ethnic identity. We present ...

Objectives: Although many trials have assessed the effect of acupuncture on knee osteoarthritis (KOA), its efficacy remains controversial. Sham acupuncture techniques are regarded as representative control interventions in acupuncture trials and sometimes incorporate the use of sham devices (base units) to support a non-penetrating needle. To achieve successful blinding, these trials also use ...

Chronic kidney disease (CKD) is an increasing health problem globally, now affecting 8-13% of the world’s population. The prevalence of CKD increases dramatically with age because kidney function, as assessed by the glomerular filtration rate (GFR), declines with age. The rate of GFR loss varies significantly between individuals regardless of known risk factors. However, current kidney biomarkers ...

Deep learning-based approaches for content-based image retrieval (CBIR) of computed tomography (CT) liver images is an active field of research, but suffer from some critical limitations. First, they are heavily reliant on labeled data, which can be challenging and costly to acquire. Second, they lack transparency and explainability, which limits the trustworthiness of deep CBIR systems. We address ...
