Extreme Bond Ionicity in Mg─Te Chalcogenides for Ultrathin Low Voltage Selector‐Only Memory beyond the Leakage Scaling Limit

Advanced Materials, EarlyView.
Mg─Te chalcogenides address the leakage scaling trade‐off in ultrathin selector‐only memory. Structural partitioning in multiphase Mg─Te, combined with highly ionic Mg─Te bonding and Hf interfacial engineering, supports reliable 5 nm thickness operation at low write voltage with suppressed leakage current, narrow threshold voltage distributions, 10 ns ...

Reducing Variability in Subthreshold Circuits [PDF]

, 2017
Reduced form-factor in portable electronics has made energy-efficiency the primary target. Subthreshold operation is a low-power technique delivering significant energy efficiency. However, circuits in subthreshold are very sensitive to process variation.

Binge and Emotional Eating in obese subjects seeking weight loss treatment [PDF]

, 2008
Objective: Binge Eating Disorder (BED) is highly prevalent among individuals seeking weight loss treatment. Considering the possible trigger factors for BED, different studies focused on the role of emotional eating. The present study compared threshold,

Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

Advanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.

Dual‐State Programmable Oxide Transistor for Time‐Based Cryptography

Advanced Materials, EarlyView.
A DUPOT enables independently tunable Vth and Isat depending on gate bias polarity, producing three‐dimensional dynamical behavior within a transfer characteristic. This behavior originates from charge trapping and oxygen‐ion migration in the HfO2 layer.

Differential mortality rates in major and subthreshold depression: meta-analysis of studies that measured both

, 2013
Background Although the association between depression and excess mortality has been well established, it is not clear whether this is greater in major depression than in subthreshold depression.

Reconciling threshold and subthreshold expansions for pion–nucleon scattering [PDF]

, 2017
Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion–nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects enhanced by large low-energy constants.
