PRODUCER RETURNS FROM COTTON STRENGTH AND UNIFORMITY: AN HEDONIC PRICE APPROACH [PDF]

open access: yes
Implicit (hedonic) producer prices for fiber strength uniformity were estimated for the southwest U.S. cotton market using seemingly unrelated regression and market sales data from 1983/84 and 1984/85, Fiber strength and length uniformity had significant

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook

open access: yesAdvanced Materials, EarlyView.
Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

Assessing the quality of complex fixed-time traffic signals [PDF]

open access: yes, 2012
Usually, the parameters of fixed-time traffic signals – which are still the most common type of signals in the world – will be determined on the basis of a characteristic traffic demand pattern.

Quasi-random testing

open access: yes, 2007
Our paper proposes an implementable procedure for using the method of quasi-random sequences in software debug testing. In random testing, the sequence of tests (if considered as points in an n-dimensional unit hypercube) will give rise to regions where ...

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

open access: yesAdvanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

Azobenzene's Cross‐Scale Optics and Photonics: Molecular Photoswitching, Mesoscopic Material Motions, and Adaptive Devices

open access: yesAdvanced Materials, EarlyView.
Azobenzene photoswitches translate molecular‐scale E/Z photoisomerization into macroscopic material responses and device‐level photonic functions. This Review highlights how azobenzene research has evolved from molecular photochemistry to photoalignment, mass migration, photomechanics, and heat release, ultimately enabling holography, reconfigurable ...

Binarized Neural Network Comprising Quasi‐Nonvolatile Memory Devices for Neuromorphic Computing

open access: yesAdvanced Electronic Materials
This study presents a binarized neural network (BNN) comprising quasi‐nonvolatile memory (QNVM) devices that operate in a positive feedback loop mechanism and exhibit an extremely low subthreshold swing (≤ 5 mV dec−1) and a high on/off ratio (≥ 107).
