Application of the Generalized Method of Moments for Estimating Continuous-Time Models of U.S. Short-Term Interest Rates [PDF]

We show by Monte Carlo simulations that the jackknife estimation of QUENOUILLE (1956) provides substantial bias reduction for the estimation of short-term interest rate models applied in CHAN ET AL. (1992) - hereafter CKLS (1992).

Multiplex Modular Nanorobotic Systems with Catalytic Activity under Magnetic Navigation

Advanced Functional Materials, EarlyView.
We present modular nanorobots composed of a magnetic propulsion module and different extension modules carrying functional activities, assembled via DNA base pairing. The system integrates propulsion, optical tracking, enzymatic catalysis, and cell docking in a programmable manner.

Division of Labour and Directed Production [PDF]

We examine a situation where efforts on different tasks positively affect production but are not separately verifiable and where the manager (principal) and the worker (agent) have different ideas about how production should be carried out: agents prefer

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

Advanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Influence of Genotype and Environment on the Diterpenes in the Wax Layer of Some Flue-cured Tobaccos/Einfluss von Genotyp und Umwelt auf die Diterpene in der Wachsschicht einiger „flue-cured“–Tabake

Contributions to Tobacco and Nicotine Research, 1981
The composition of the wax layer of some flue-cured tobaccos that were grown under the same conditions in the U. S. A., Brazil and Germany was examined by means of GC and GC/MS.

Nonparametric Regression on Latent Covariates with an Application to Semiparametric GARCH-in-Mean Models [PDF]

We consider time series models in which the conditional mean of the response variable given the past depends on latent covariates. We assume that the covariates can be estimated consistently and use an iterative nonparametric kernel smoothing procedure ...

A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

Advanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...

Lead-free relaxor ferroelectric thin films with enhanced energy density through process optimization

Communications Materials
Dielectric capacitors used as energy storage components in electrical and electronic systems offer ultrafast charge and discharge rates but have long faced the challenge of insufficient recoverable energy storage density.

A Novel Device for Functional Evaluation of Gas Sensing Layers

Proceedings, 2018
Chemical gas sensors are operated at elevated temperatures and the actual temperature has a tremendous influence on sensitivity and selectivity. From that perspective, precise temperature control over the chip is an absolute requirement. Next to a stable

The (Economic) Effects of Lay Participation in Courts - A Cross-Country Analysis [PDF]

Legal philosophers like Montesquieu, Hegel and Tocqueville have argued that lay participation in judicial decision-making would have benefits reaching far beyond the realm of the legal system narrowly understood.
