This research aims to evaluate the achievement of rural development in study area after UNESCO designated Toba Caldera Geopark as a member Global Network (GGN) July 2020. For that purpose, authors conduct measure relationship geotourism with area. The methods employed are library research, discussion, observation, field trips and questionnaires 127 respondents from village government officers, ...

OBJECTIVES This work was a comparative study that aimed to find a proper method for accurately segmenting persistent ground glass nodules (GGN) in thin-section computed tomography (CT) images after detecting them. METHODS To do this, we first applied five types of semi-automatic segmentation methods (i.e., level-set-based active contour model, localized region-based active contour model, seed...

OBJECTIVE The relationship between serum testosterone (T) levels, muscle mass and muscle force in eugonadal men is incompletely understood. As polymorphisms in the androgen receptor (AR) gene cause differences in androgen sensitivity, no straightforward correlation can be observed between the interindividual variation in T levels and different phenotypes. Therefore, we aim to investigate the re...

PURPOSE To compare manual measurements of diameter, volume, and mass of pulmonary ground-glass nodules (GGNs) to establish which method is best for identifying malignant GGNs by determining change across time. MATERIALS AND METHODS In this ethics committee-approved retrospective study, baseline and follow-up CT examinations of 52 GGNs detected in a lung cancer screening trial were included, r...

In this letter, we investigate the performance of reconfigurable intelligent surface (RIS)-assisted communications, under assumption generalized Gaussian noise (GGN), over Rayleigh fading channels. Specifically, consider an RIS, equipped with $N$ </inl...

Abstract Optimization problems that include regularization functions in their objectives are regularly solved many applications. When one seeks second-order methods for such problems, it may be desirable to exploit specific properties of some these when accounting curvature information the solution steps speed up convergence. In this paper, we propose SCORE (self-concordant regularization) fram...

The gravitational coupling of nearby massive bodies to test masses in a wave (GW) detector cannot be shielded, and gives rise 'gravity gradient noise' (GGN) the detector. In this paper we show that for any GW using local Inner Solar System, GGN from motion field $\sim 10^5$ System asteroids presents an irreducible noise floor detection rises exponentially at low frequencies. This severely limit...
