Welcome to the Signal Integrity and Power Column!
identification of rapid degradation of ecological resources requires effective environmental monitoring including ecological integrity assessment .our first aim is to analyze ecological integrity in a landscape context while developing a method to assess integrity in spite of a dearth of historical data. we used a spatial-temporal reference framework for land cover maps for assessing ecologica...
Obesity, commonly measured with body mass index (BMI), is associated with numerous deleterious health conditions including alterations in brain integrity related to advanced age. Prior research has suggested that white matter integrity observed using diffusion tensor imaging (DTI) is altered in relation to high BMI, but the integrity of specific white matter tracts remains poorly understood. Ad...
The concept of integrity, as a factor of sustaining values and significance of cultural heritage, is considered to be a key element in the process of urban heritage conservation. Review and analysis of documents, conventions and theories concerning the role of integrity in urban heritage conservation shows that in recent decades, the concept of integrity has attracted attention worldwide in the...
Front Cover: In article 2300090, Seda Kizilel, Erkan Senses, and co-workers entrap liposomes- artificial models of biological cells- in PEG hydrogels mimicking various tissue environments. The liposomes are shown to escape from the hydrogel meshes response large oscillatory shear deformation due repeated stretching releasing network strands without losing their structural integrity.
From the time of antiquity two lines of thinking were always predominant, the materialistic and the spiritualistic viewpoint. The materialistic point of view states the human beings and other living creatures come to life according to a specific pattern and constellation of chemicals and molecules. On the other hand, the nonmaterialistic view point emphasizes that the life factor is something...
AIM A porcelain-fused-to-metal (PFM) veneer crown restoration is considered successful when biological, mechanical, and esthetical concerns are satisfied. Restorations with poor marginal integrity may contribute to the cause of severe caries and periodontal defects. The most important factor in achieving successful marginal integrity is preparation design. Although a sloping shoulder preparatio...
Integrity checking is a crucial issue, as databases change their instance all the time and therefore need to be checked continuously and rapidly. Decades of research have produced a plethora of methods for checking integrity constraints of a database in an incremental manner. However, not much has been said about when to check integrity. In this paper, we study the differences and similarities ...
if we think of the graph as modeling a network, the vulnerability measure the resistance of the network to disruption of operation after the failure of certain stations or communication links. many graph theoretical parameters have been used to describe the vulnerability of communication networks, including connectivity, integrity, toughness, binding number and tenacity.in this paper we discuss...
• A multi-taxa Index of Biological Integrity can increase sensitivity to disturbance. Using multiple wetland classes improves consistency. Mix and match approach monitoring cost-effectiveness. Wetland indices biological integrity (IBIs) are a common component in the water resources as required by United States’ Clean Water Act (CWA). The effectiveness an IBI monitor disturbance is dependent on ...
