Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Modeling D2D communications with LTE and WiFi [PDF]

ACM SIGMETRICS Performance Evaluation Review, 2014
In this work we propose a roadmap towards the analytical understanding of Device-to-Device (D2D) communications in LTE-A networks. Various D2D solutions have been proposed, which include inband and outband D2D transmission modes, each of which exhibits different pros and cons in terms of complexity, interference, and spectral efficiency achieved. We go

Measuring Interactional Competence in a Japanese University EFL Speaking Context

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The ability to interact is an integral aspect of speaking proficiency. Therefore, methods of assessing interaction need to be incorporated into second language (L2) speaking tests. The main purpose of this exploratory study is to attempt to quantify interactional competence (IC) in a Japanese university EFL (English as a foreign language ...

Changed Minds and L2 Motivation: Reflections of Japanese EFL Students Living, Laboring and Learning in Vietnam

International Journal of Applied Linguistics, EarlyView.
ABSTRACT English as a lingua franca (ELF) is increasingly used for communication in many EFL contexts, including Vietnam. Although Japan and Vietnam have a long history of economic cooperation, for practical reasons, English typically functions as the medium of communication between the two groups. This study examines Japanese expats who had studied or
