Lamb modes with zero group velocity at nonzero wave numbers correspond to local and stationary resonances in isotropic plates. Lamb modes can be utilized for nondestructive evaluation of the elastic properties and thickness. One example of an application is the testing of plate-like concrete structures. In this example, continuous variation in the material velocity through the thickness may occur.

Background: Borderline ovarian tumors (BOTs) are a subgroup of ovarian malignancies with low malignant potential. Very limited earlier data are available on familial clustering of BOTs with other cancers. We aim to explore histology-specific familial associations among BOTs and associations between BOTs and any invasive cancers.Methods: On the basis of 16.1 million individuals in the Swedish Famil

This paper presents an ongoing research project investigating the use of bibliometrics for research evaluation and resource allocation purposes, and to investigate the effects of these evaluation models on individual, organizational and political levels. A main focus has been on bibliometrics based evaluation practices. The use of bibliometrics for local resource allocation at Swedish universities

Wavelet networks (WNs) were introduced in 1992 as a combination of artificial neural radial basis function (RBF) networks and wavelet decomposition. Since then, however, WNs have received only a little attention. We believe that the potential of WNs has been generally underestimated. WNs have the advantage that the wavelet coefficients are directly related to the image data through the wavelet tra

There are many projects in Mozambique for poverty reduction. One of these projects is funded by Millennium Challenge Account (MCA) and is aimed to install a total of 600 rural water points in the province of Nampula and Cabo Delgado in crystalline rock zone. Each water point consists of a drilled well, a water pump and a communal washing basin. Vertical Electrical Sounding (VES) was used for asses

In aqueous solution of 1,1'-diethyl-2,2'-carbocyanine J-aggregate, the exciton self-trapped (EST) state is usually expected to be negligible. However, in this work, by measuring transient absorption spectroscopy under a variety of excitation fluences, the EST state was found to be formed via coherent exciton-exciton annihilation (EEA), when the excitation fluence was high enough. With the existenc

Patent citations added by examiners are often used as indicators of technological impact and knowledge flows, despite various criticisms. In this study we analyze the distribution of examiner patent citations according to patent characteristics in order to show their limitations. According to our findings, the number of applicant citations included is dependent on the science-base of the technolog

Maps of the MT-saturation as derived in FLASH-based multi-parameter mapping (MPM) are largely corrected for effects of flip angle inhomogeneity. Here, we present a heuristic model for residual effects of B1+ that is rooted in the dynamics of macromolecule saturation. Model parameters were validated for brain tissues by variation of the MT-pulse flip angle in an established MPM protocol. White and
