Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

A Zero-Inflated Box-Cox Normal Unipolar Item Response Model for Measuring Constructs of Psychopathology [PDF]

, 2018
This research introduces a latent class item response theory (IRT) approach for modeling item response data from zero-inflated, positively skewed, and arguably unipolar constructs of psychopathology. As motivating data, the authors use 4,925 responses to

Prefronto-cerebellar transcranial direct current stimulation increases amplituded and decreases latency of P3b component in patients with euthymic bipolar disorder [PDF]

, 2015
INTRODUCTION: Neurocognitive impairments have been observed in patients with bipolar disorder (BD) even during the euthymic phase of the disease, potentially representing trait-associated rather than state-associated characteristics of the disorder.

Bipolar depression versus unipolar depression: demographic and clinical differences

Middle East Current Psychiatry
Background Unipolar depression (UD) and bipolar depression (BD) are both characterized by depressive symptoms. In clinical practice, it is hard to distinguish between BD and UD. This often results in misdiagnosis of BD.

The Negativity Bias Predicts Response Rate To Behavioral Activation For Depression [PDF]

, 2016
Background and Objectives: This treatment study investigated the extent to which asymmetric dimensions of affective responding, specifically the positivity offset and the negativity bias, at pretreatment altered the rate of response to Behavioral ...

Diagnosis of unipolar and bipolar depressions and their specifiers

Medicina, 2017
Depression is a common, recurrent and chronic disease with a high prevalence in the world population. It is a disease that affects the individual organism as a whole, affecting, in addition to mood, cognitive, neuroendocrine and physiological functions ...

Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Magnetic fields and flows between 1 AU and 0.3 AU during the primary mission of HELIOS 1 [PDF]

, 1978
The recurrent flow and field patterns observed by HELIOS 1, and the relation between these patterns and coronal holes are discussed. Four types of recurrent patterns were observed: a large recurrent stream, a recurrent slow (quiet) flow, a rapidly ...
