MEASURING INEFFICIENCY IN THE PRESENCE OF AN EXPORT TAX, AN IMPORT TARIFF, AND A STATE TRADING ENTERPRISE

open access: yes
Agricultural sales cooperative unions (ASCUs) in Turkey are heavily influenced by both domestic and international government policies. Both export taxes and import tariffs are used as policy tools to regulate cotton markets.

Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...

Firm-Heterogeneity, Persistent and Transient Technical Inefficiency

open access: yes
This paper provides a new model that disentangles firm effects from persistent (time-invariant/long-term) and transient (time-varying/short-term) technical inefficiency.Bayesian analysis; Markov Chain Monte Carlo; Technical efficiency.

Making noisy data sing : a micro approach to measuring industrial efficiency [PDF]

open access: yes
Technical, scale and allocative inefficiency are widely believed to plague the industrial sectors of developing countries. This paper presents a way to measure this inefficiency with imperfect data. There is great interest in documenting the patterns and

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Multimodal Haptic Perception Through Synergistic Nanocomposite Sensor Arrays

open access: yesAdvanced Materials Technologies, EarlyView.
Multi‐modal fingertip haptics are advanced through a bioinspired &vertical‐via' electronic skin architecture. A confined PDMS/MWCNT/NiNP nanocomposite, sitting at the percolation threshold, enables tactile, thermal, and magnetic sensing. A unique via‐density gradient and dedicated &Un‐Touch' reference nodes provide robust spatial resolution and signal ...
