The structure of the Ga terminated GaAs(100)-c(8x2) surface has been a topic under debate during the last decade. A complex model involving strong reconstructions was recently proposed after extensive Total Energy calculation[1], and was also confirmed by Low Energy Electron Diffraction (LEED) dynamical calculations[1]. Further studies, based on X-ray Diffraction techniques (SXRD), basically co...

In this paper we present an eecient design for message passing over a reeective memory network. First, we consider the attributes of reeec-tive memory communication networks and the requirements to eeciently build message-passing functional-ity on these networks. We then introduce the Bill-Board Protocol, a lock-free protocol which provides low-latency send, receive, and multicast functionality...

Abstract: In this paper, we present algorithms for efficiently implementing three collective communication operations on reflective memory network clusters: Broadcast, Barrier Synchronization and All-Reduce. These algor...

Two sets of opaque water-based acrylic coatings were prepared with IR-reflective pigments and conventional pigments. The objective of this work was to determine the efficiency of IR-reflective pigments in limiting the heat buildup of opaque coating formulations. Experiments performed on PVC substrates revealed that IR-reflective pigments significantly decreased the temperature increase above ro...

Initiation into contextualizing mindful second language teacher education (SLTE) has challenged teacher educators causing their retreat into mindless submission to ready-made standardized directives. To revive the starting perspective in curriculum development in light of the recent trend towards responsive SLTE, this practitioner research investigated how the context was incorporat...

Computational reflection is gaining interest in practical applications: modern software frequently requires strong adaptability conditions to be met in order to fit a heterogenous and evolving computing environment. Most of these applications only need limited but flexible reflective capabilities rather than sophisticated reflective languages and reflective runtime systems. However, there is no...

Employing self-study methodology this work examines not only the transition from classroom teacher to educator but also increased complexity of experience while teaching online during pandemic, and back some sense normalcy with in person. Data sources include Author One’s reflective journal, recordings meetings critical friends providing feedback throughout process, student artifacts different ...
