Advanced Science, EarlyView.Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.

The role of technology and institutions for growth: Danish creameries in the late nineteenth century [PDF]
We consider the relative contributions of changing technology and institutions for economic growth through the investigation of a natural experiment in history: the almost simultaneous introduction of the automatic cream separator and the cooperative ...

On estimating the effectiveness of resources. A local maximum likelihood frontier approach on care for students [PDF]
To study education as a complex production process in a noisy and heterogeneous setting, this paper suggests to using a stochastic frontier model estimated by a local maximum likelihood approach (LMLSF). The LMLSF smoothly combines the virtues of the non-

Advanced Science, EarlyView.Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

Does accounting for inefficiency affect the time-varying short and long-run returns to scale? [PDF]
The returns to scale for nineteen South Asian countries are estimated using window and cumulative rolling stochastic frontier regression analysis. The stochastic frontier analysis accounts for technical inefficiency of Hicks non-neutral technology ...

Advanced Electronic Materials, EarlyView.Ising machines are emerging as specialized hardware solvers for computationally hard optimization problems. This review examines five major platforms—digital CMOS, analog CMOS, emerging devices, coherent optics, and quantum systems—highlighting physics‐rooted advantages and shared bottlenecks in scalability and connectivity.

Estimation of Losses Due to the Existence of Monopolies in Urban Bus Transport in Poland [PDF]
Yearbook of Antitrust and Regulatory Studies, 2011 The aim of this paper is to present the different approaches to demonopolisation used in Polish and European urban public transport, compare the efficiency of these models which have proven popular in Poland as well as to estimate the total losses ...

Accounting for heterogeneity in the measurement of hospital performance [PDF]
With prospective payment of hospitals becoming more common, measuring their performance is gaining in importance. However, the standard cost frontier model yields biased efficiency scores because it ignores technological heterogeneity between hospitals ...

Institutions and Bank Performance: A Stochastic Frontier Analysis*
Oxford Bulletin of Economics and Statistics, 2007 AbstractThis article investigates the impact of institutions on bank efficiency and technology, using a stochastic frontier analysis of a data set of 7,959 banks across 136 countries over 10 years. The results confirm the importance of well‐developed institutions for the efficient operation of commercial banks.
