   The speed of NTRU-based Key Encapsulation Mechanisms (KEMs) in software, especially on embedded software platforms, is limited by the long execution time of its primary operation, polynomial multiplication. In this paper, we investigate the potential for speeding up the implementations of four NTRU-based KEMs, using software/hardware codesign, when targeting Xilinx Zynq UltraScale+ multiprocessor system-on-chip (MPSoC). All investigated algorithms compete in Round 1 of the NIST PQC standardization process. They include: ntru-kem from the NTRUEncrypt submission, Streamlined NTRU Prime and NTRU LPRime KEMs of the NTRU Prime candidate, and NTRU- HRSS-KEM from the submission of the same name. The most time-consumingmore »operation, polynomial multiplication, is implemented in the Programmable Logic (PL) of Zynq UltraScale+ (i.e., in hardware) using constant-time hardware architectures most appropriate for a given algorithm. The remaining operations are executed in the Processing System (PS) of Zynq, based on the ARM Cortex-A53 Application Processing Unit. The speed-ups of our software/hardware codesigns vs. purely software implementations, running on the same Zynq platform, are determined experimentally, and analyzed in the paper. Our experiments reveal substantial differences among the investigated candidates in terms of their potential to benefit from hardware accelerators, with the special focus on accelerators aimed at offloading to hardware only the most time-consuming operation of a given cryptosystems. The demonstrated speed-ups vs. functionally equivalent purely software implementations vary between 4.0 and 42.7 for encapsulation, and between 6.4 and 149.7 for decapsulation.« less
2. VSI: Edu*-2016 - Keeping up with technology: Teaching Parallel, Distributed and High-Performance Computing

   Prasad, Sushil K. ; Ghafoor, Sheikh ; Kaklamanis, Christos ; Vaidyanathan, Ramachandran ( August 2018 , Journal of parallel and distributed computing)

   This special issue is devoted to progress in one of the most important challenges facing computing education.The work published here is of relevance to those who teach computing related topics at all levels, with greatest implications for undergraduate education. Parallel and distributed computing (PDC) has become ubiquitous to the extent that even casual users feel their impact. This necessitates that every programmer understands how parallelism and a distributed environment affect problem solving. Thus,teaching only traditional, sequential programming is no longer adequate. For this reason, it is essential to impart a range of PDC and high performance computing (HPC) knowledge andmore »skills at various levels within the educational fabric woven by Computer Science (CS), Computer Engineering (CE), and related computational science and engineering curricula. This special issue sought high quality contributions in the fields of PDC and HPC education. Submissions were on the topics of EduPar2016, Euro-EduPar2016 and EduHPC2016 workshops,but the submission was open to all. This special issue includes 12 paper spanning pedagogical techniques, tools and experiences.« less

4. Proceedings of the 11th International Conference on Porous Metals and Metallic Foams (MetFoam 2019)

   https://doi.org/10.1007/978-3-030-42798-6  

   A Abaidi, Abou Horeira ( January 2019 , Proceedings of the 11th International Conference on Porous Metals and Metallic Foams (MetFoam 2019))

   MetFoam 2019 is the 11th edition of the biannual International Conference on Porous Metals and Metallic Foams; it was heled in Dearborn, Michigan, USA between August 20 and 23, 2019. Previous editions were held in various cities around the world starting in Bremen, Germany in 1999. This conference is the largest cross-disciplinary, international technical meeting focused exclusively on the production, properties, and applications of these lightweight multifunctional porous materials. In Dearborn, a total of 115 presentations were delivered at the conference by participants from 17 countries. Many participants travelled long distances to present and attend the conference. Students delivered 40%more »of the presentations. Emerging areas such as additive manufacturing and freeze casting, as well as nanoporous materials, cellular materials, and metallic metamaterials were covered by some of the presenters. The proceedings volume of MetFoam 2019 is the culmination of several months of work, which included the preparation of the papers by the authors, editing, and reviewing. The papers collected in this volume provide a representative snapshot of the research activity in the field. It is my sincere hope that this proceedings volume will remain a valuable record of MetFoam 2019, and that it will serve as a reference for researchers interested in porous metals and metallic foams. I would like to thank the reviewers and the session chairs for volunteering their precious time and effort. The International Scientific Board and the Steering Committee of MetFoam 2019 provided indispensable input and guidance throughout the planning of the conference. Thanks are also due to Kelcy Wagner and Trudi Dunlap from our organization partner The Minerals, Metals & Materials Society (TMS) for their assistance in the production of the proceedings volume, as well as for their vital hard work during the organization phase of the conference. Certainly, a special thanks go to our sponsors and exhibitors for making the event possible.« less
5. “It’s all in the moment”: a mixed-methods study of elementary science teacher adaptiveness following professional development on knowledge generation approaches

   Abstract This special edition is based on the revelation that “the lessons learned and unlearned during COVID-19 grant us an unparalleled opportunity to reflect.” Here, we reflect on lessons learned related to teacher adaptiveness. We examined how the COVID-19 pandemic demonstrated the adaptiveness necessary for teachers to knowledge generation approaches aligned with the Next Generation Science Standards. First, we outline a three-year professional development program focused on knowledge generation approaches. We present findings from teachers’ experiences teaching science from 2019 to 2021, collected through consecutive form explanatory mixed-methods analysis involving written responses to vignettes ( n  = 474) and classroom observationsmore »( n  = 58). Then, using an individual teacher case study, we explore how the shift to virtual teaching was supported by adaptiveness. Results suggest a significant relationship between teacher adaptiveness and the use of knowledge generation approaches. We conclude with implications for elementary science teacher professional development and present questions for further research on adaptiveness.« less
