In underdoped cuprates, Tc is thought to be determined by Cooper pair phase fluctuations because of the small superfluid density ns. Experimentally, Tc is found to scale with ns. The fluctuation-exchange approximation (FLEX) in its standard form fails to predict this behavior of Tc since it does not include phase fluctuations. We therefore extend the FLEX to include them selfconsistently. We pr...

Parameterized password guessability—how many guesses a particular cracking algorithm with particular training data would take to guess a password—has become a common metric of password security. Unlike statistical metrics, it aims to model real-world attackers and to provide per-password strength estimates. We investigate how cracking approaches often used by researchers compare to real-world c...

Flex sensors can be usefully adopted as mechanical-electrical transducers to measure human joint movements, since their electrical resistance varies proportionally to the angle assumed by the joint under measure. Over time, these sensors have been investigated in terms of mechanical and electrical behavior, but no reports have detailed the possibility of their adoption not just on top but under...

It is with great pleasure that we present this Special Issue for IEEE Journal on Flexible Electronics (J-FLEX), dedicated to the extended papers from 2022 International Conference Flexible, Printable Sensors and Systems (FLEPS), held in Vienna, Austria. FLEPS sponsored by Council, one of our leading J-FLEX sponsors. As Guest Editorial Board, are delighted bring together a collection cutting-edg...

FLEX is a new cost eeective, \locality aware" load balancing solution for a shared web hosting service implemented on a cluster of machines 3]. FLEX allocates hosted web sites to diierent machines in the cluster based on the sites' processing and memory requirements which are estimated using the site logs. Appropriate routing of requests can be achieved by using the DNS infrastructure, since ea...

For treatment of critical heart valve diseases, prosthetic valves perform fairly well in most adults; however, for pediatric patients, there is the added requirement that the replacement valve grows with the child, thus extremely limiting current treatment options. Tissue engineered heart valves (TEHV), such as those derived from autologous bone marrow stem cells (BMSCs), have the potential to ...

It is extremely difficult to predict the initiation time of cracking due to a large time spread in most cracking experiments. Thus, probabilistic models, such as the Weibull distribution, are usually employed to model the initiation time of cracking. Therefore, the parameters of the Weibull distribution are estimated from data collected from a cracking test. However, although the development of...

The mechanics of cracking in fiber-reinforced ceramic matrix composites (CMCs) under general loadings remains incomplete. The present paper addresses one outstanding aspect of this problem: the development of matrix cracks in unidirectional plies under shear loading. To this end, we develop a model based on potential energy differences upstream and downstream of a fully bridged steady-state mat...

ANALYTICAL AND EXPERIMENTAL STUDY OF INVESTMENT CASTING WITH LASER STEREOLITHOGRAPHY MODELS by Wen-Long Yao This dissertation presents an analytical and experimental investigation of ceramic shell cracking during the burnout process in investment casting with internally webbed laser stereolithography (SLA) patterns. Included in the consideration are the cracking temperature of the ceramic shell...
