A novel quality assessment for visual secret sharing schemes

To evaluate the visual quality in visual secret sharing schemes, most of the existing metrics fail to generate fair and uniform quality scores for tested reconstructed images. We propose a new approach to measure the visual quality of the reconstructed image for visual secret sharing schemes. We developed an object detection method in the context of secret sharing, detecting ...

Behaviour of Model Square Footing Resting on Sand Reinforced with Three-Dimensional Geogrid

The present investigation proposes a new type of reinforcing material in the form of three-dimensional geogrid. The performance of a model square footing resting on the three-dimensional geogrid reinforced sand bed is investigated by conducting laboratory scaled plate load tests. Two types of 3D geogrids with triangular and rectangular pattern were used. The improvement in bearing ...

Evolving network structure of academic institutions

Today’s colleges and universities consist of highly complex structures that dictate interactions between the administration, faculty, and student body. These structures can play a role in dictating the efficiency of policy enacted by the administration and determine the effect that curriculum changes in one department have on other departments. Despite the fact that the features of ...

[64Cu]NOTA-pentixather enables high resolution PET imaging of CXCR4 expression in a preclinical lymphoma model

Background The chemokine receptor 4 (CXCR4) is an important molecular target for both visualization and therapy of tumors. The aim of the present study was the synthesis and preclinical evaluation of a 64Cu-labeled, CXCR4-targeting peptide for positron emission tomography (PET) imaging of CXCR4 expression in vivo. Methods For this purpose, 1,4,7-triazacyclononane,1-glutaric ...

Agent-based modelling for urban sprawl in the region of Waterloo, Ontario, Canada

Agent-based modelling (ABM) is a form of simulation that is phenomenal in understanding and exploring various types of spatial and non-spatial problems. The goal of this research is to study agent-based modeling in an urban context. ArcGIS was used to develop cost raster. In the second part, NetLogo was used to create agents for the purpose of stochastic simulation of urban sprawl ...

Transitioning from an economic cluster to a collaborative community: mining projects in Greenland

This paper analyzes the Greenlandic business community and the recently established cluster relevant to extractive industries in Greenland, Arctic Cluster of Raw Materials (ACRM), to enhance local business development in mining projects in Greenland. The analysis directs toward a transition from an economic cluster to a collaborative community in order to increase business ...

On settlement prediction of soft clay reinforced by a group of stone columns

This paper studies the behavior of a foundation on a soil reinforced by a group of end-bearing stone columns in terms of settlement reduction in oedometer condition. The group of stone columns has been reduced to equivalent concentric crowns using a finite-difference FLAC3D modeling. The obtained numerical results were compared to existing analytical and numerical methods for the ...

Predictors of happiness among retired from urban and rural areas in Brazil

This study compared differences in degree of happiness, social support, activities performed, and health and economic situation among retirees from urban and rural areas in Minas Gerais State in Brazil. The influences of these predictors over individuals’ level of happiness were also analyzed. We included 279 retired individuals living in Abre Campo (a municipality with a ...

Low-complexity lattice reduction algorithm for MIMO detectors with tree searching

In this paper, we propose a low-complexity lattice reduction (LR) algorithm for multiple-input multiple-output (MIMO) detectors with tree searching. Whereas conventional approaches are based exclusively on channel characteristics, we focus on joint optimisation by employing an early termination criterion in the context of MIMO detection. In this regard, incremental LR (ILR) was ...

SPH propagation back-analysis of Baishuihe landslide in south-western China

Background Landslides and landslide dams are a major natural hazard causing high socioeconomic risk in inhabited mountainous areas. This is also true for vast parts of south-western China, which are highly prone to slope failures due to several factors, such as a humid climate with high precipitation in the summer months, geological predisposing factors with highly weathered ...

Destabilization and off-flavors generated by Pseudomonas proteases during or after UHT-processing of milk

Background Pseudomonads play a major role in the spoilage of UHT processed dairy products, due to their growth-related protease production in raw milk. Results To assess the off-flavor generating capacity of these AprX proteases in milk after UHT-processing, six major milk spoiling Pseudomonas groups were investigated. Sensory evaluation of the different processed milk samples ...

Understanding diversity: a Dutch case study on teachers’ attitudes towards their diverse student population

Background In the Netherlands, there has been a strong increase in diversity among students in recent decades. Even though access for previously underrepresented groups based on economic status, ethnicity or culture has been realised to a certain extent, differences in student performance between groups persist. Research shows that teacher performance influences student achievement ...

Importance of Radioactive Labelling to Elucidate Inositol Polyphosphate Signalling

Inositol polyphosphates, in their water-soluble or lipid-bound forms, represent a large and multifaceted family of signalling molecules. Some inositol polyphosphates are well recognised as defining important signal transduction pathways, as in the case of the calcium release factor Ins(1,4,5)P3, generated by receptor activation-induced hydrolysis of the lipid PtdIns(4,5)P2 by ...

Microbiological quality of lettuce (Lactuca sativa) irrigated with wastewater in Addis Ababa, Ethiopia and effect of green salads washing methods

Background In Addis Ababa, where irrigation water for vegetable production is commonly derived from the highly polluted Akaki river, information on microbial contamination of water and irrigated vegetable is scanty. An assessment was done to determine the microbiological quality of irrigation water and lettuce harvested from 10 urban farming sites of Addis Ababa. The efficacy of 5 ...

Analytic Complexity and Challenges in Identifying Mixtures of Exposures Associated with Phenotypes in the Exposome Era

Purpose of Review Mixtures, or combinations and interactions between multiple environmental exposures, are hypothesized to be causally linked with disease and health-related phenotypes. Established and emerging molecular measurement technologies to assay the exposome, the comprehensive battery of exposures encountered from birth to death, promise a new way of identifying mixtures ...

Effect of Traffic Signal Countdown Timers on Pedestrian Crossings at Signalized Intersection

Installations of signal countdown timers (SCTs) adjacent to the traffic signal heads are on the rise at several intersection locations in India. These SCTs provide information related to the time left for a particular signal phase and thus expected to help the driver take better decision. But no scientific studies were carried out before their installations at intersection ...

Photo-id of blue whale by means of the dorsal fin using clustering algorithms and color local complexity estimation for mobile devices

We present an automatic program of blue whale photo-identification for mobile devices. The proposed technique works in the wavelet domain to reduce the image size and the processing time of the proposed algorithm, and with an edge enhancement filter, the characteristics of the blue whale are preserved. Additionally, an image palette reduction algorithm based on local image ...

Every breath you take: physiology and the ecology of knowing in meditative practice

As a physiologist interested in contemplative practice and meditation I have enjoyed the opportunity of lecturing to students engaged in the study of contemplation. My pedagogic role was to expose them to some of what we know of the biological phenomena that are or may be taking place during various meditative states — explicating for them the details of how the human body actually ...
