Wheat Productivity, Efficiency, and Sustainability: A Stochastic Production Frontier Analysis [PDF]
This paper uses the farm-level survey data to estimate the stochastic frontier production function incorporating inefficiency effects. Sufficient evidence of positive relationship between wheat productivity and higher and balanced use of fertiliser ...

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals
Advanced Functional Materials, EarlyView.Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...

RISK ANALYSIS OF CROPPING SYSTEMS USING EXPERIMENTAL CROPPING SYSTEM-FERTILIZER DATA [PDF]
Using 11 years of experimental crop yields by cropping systems and fertilizer level, a MOTAD frontier was developed. This analysis allowed yield, cost, and stability interactions arising from crop sequences to be implicitly included. Target-MOTAD, Safety-

Advanced Functional Materials, EarlyView.The carbon cloth electrode with targeted pyridinic nitrogen doping, achieved via urea pyrolysis, effectively modulates the adsorption of Cr(II) species and enhances electron transfer, leading to significantly improved kinetics of the Cr(II)/Cr(III) reaction. The material demonstrates a high discharge capacity of 689.3 mAh and an energy efficiency of 72.

Advanced Functional Materials, EarlyView.Ferroelectric memcapacitors enable non‐volatile, voltage‐programmable capacitance tuning for adaptive electronics. A TiN/HfZrO/TiN device stack demonstrates more than eight stable capacitance states within a 24 pF memory window in compact 60 ×$\times$ 60 μm2$\umu{\rm m}^{2}$ devices at low operating voltages.

Cost and profit efficiency of banks in Haiti: do domestic banks perform better than foreign banks? [PDF]
I use the stochastic frontier methodology to estimate a cost and a profit frontier functions. The Fourier-flexible form is used in this paper because of its flexibility.

Advanced Functional Materials, EarlyView.ABSTRACT In this work, we introduce a trifluoromethoxy (OCF3) group as a pseudo‐halogen terminal group design for non‐fullerene acceptors, which combines strong inductive electron‐withdrawing ability with moderate resonance donation. The as‐synthesized BTP‐OCF3, when benchmarked against its methoxy analogue BTP‐OCH3, demonstrates narrowed bandgap ...
