What Explains High Commodity Price Volatility? Estimating a Unified Model of Common and Commodity-Specific, High- and Low-Frequency Factors [PDF]

We estimate a model of common and commodity-specific, high- and low-frequency factors, built on the spline-GARCH model of Engle and Rangel (2008) to explain the period of exceptionally high price volatility in commodity markets during 2006-2008.

Solution Shearing of Sustainable Aluminum Oxide Thin Films for Compliance‐Free, Voltage‐Regulated Multi‐Bit Memristors

Advanced Electronic Materials, EarlyView.
Solution shearing technique is reported to fabricate sustainable 15 nm AlOx thin films using de‐ionized water. Thermal annealing and deep UV exposure application assist the film formation. These films exhibit two‐order bipolar resistive switching, 100 cycles endurance, and >40 h retention. The compliance‐free memristor shows eight switching states with

The Volatility of Realized Volatility [PDF]

Using unobservable conditional variance as measure, latent–variable approaches, such as GARCH and stochastic–volatility models, have traditionally been dominating the empirical finance literature.

Pulse Dynamics in Reduced Graphene Oxide Electrolyte‐Gated Transistors: Charge Memory Effects and Mechanisms Governing the Ion‐To‐Electron Transduction

Advanced Electronic Materials, EarlyView.
The time‐dependent current response of reduced graphene oxide (rGO) electrolyte‐gated transistors (EGTs) is evaluated via pulsed voltage measurements. A complex interplay between ion entrapment, electrical double‐layer formation, and charge transfer processes is observed.

Does the weather affect stock market volatility? [PDF]

This paper investigates the empirical association between stock market volatility and investor mood-proxies related to the weather (cloudiness, temperature and precipitation) and the environment (nighttime length).

Ohmic Response in BiFeO3 Domain Walls by Submicron‐Scale Four‐Point Probe Resistance Measurements

Advanced Electronic Materials, EarlyView.
Lateral transport measurements of multiferroic domain walls (DWs) in BiFeO3 thin films employing a novel, lithography‐free method are presented. Using a submicron‐scale multi‐point probe (MPP), ohmic DW conduction behavior is demonstrated, including the first collinear, four‐point resistivity value of a single DW, free of contact resistances.

Dynamic relationship between volume and volatility in the Chinese stock market: evidence from the MS-VAR model

Data Science and Management
Since market uncertainty, or volatility, serves as a crucial gauge for assessing the traits of market fluctuations, the link between stock market volume and price continues to be a focal point of interest in finance.

Charge Injection and Transport in an Isoindigo‐Based Polymer Transistor

Advanced Electronic Materials, EarlyView.
This study presents the charge injection and transport properties of field‐effect transistors based on an isoindigo‐bithiophene donor‐acceptor polymer semiconductor contacted with thiolated self‐assembled monolayer (SAM)‐functionalized electrodes. Temperature‐dependent contact characteristics are measured and simulated.
