Selective Reshaping: China’s Paradigm Shift in International Economic Governance

Abstract In contrast with the selective adaptation approach toward external norms seen in its accession to the World Trade Organization, China increasingly plays a proactive role on the international stage, with the Belt and Road Initiative at the center of these activities. How can we understand this new approach by China toward international economic governance? What is responsible for China’s shifting approach, and what are the implications of this shift? The paper presents selective reshaping as a new theoretical framework, and argues that China is shifting toward the selective reshaping of institutions and rules within the global economic order. Within this theoretical framework, perception and conception, complementarity and legitimacy are influencing components that affect selective reshaping, and which manifest substantially differently in this context, when compared with selective adaptation. Selective reshaping is likely to transform the institutions and rules within the international economic order, and carry long-term implications.

Compressed and canalized emission of quantum emitters in MIM nano-cavities

Photon-mediated interactions in quantum systems represent a crucial point in quantum mechanics for the design and analysis of scalable quantum information systems. In this communication we numerically demonstrate that quantum emitters can interact coherently with a sub-wavelength plasmonic nano-cavity. In particular, we report how the interplay between the near field of quantum emitters and the gap plasmon field can induce a striking canalization of the emission. This effect is observed in a cascade of metal–insulator–metal nanostructures (MIM), interlocked by a nano-cavity containing the quantum emitters, where the selective reshaping of the radiated field occurs. Our study pave the way for the implementation of cavity-mediated quantum gates and for the realization of scalable and tunable quantum systems.

Fabrication of Hybrid Nanostructures via Nanoscale Laser‐Induced Reshaping for Advanced Light Manipulation

Ordered hybrid nanostructures for nanophotonics applications are fabricated by a novel approach via femtosecond laser melting of asymmetric metal-dielectric (Au/Si) nanoparticles created by lithographical methods. The approach allows selective reshaping of the metal components of the hybrid nanoparticles without affecting the dielectric ones and is applied for tuning of the scattering properties of the hybrid nanostructures in the visible range.

The Value of Occlusion in Dentistry: A Clinical Report Showing the Correction of an Anterior Reverse Articulation with Selective Occlusal Adjustment.

The subject of occlusion has been deemphasized by academia over the last 30 years. This marginalization in turn has negatively impacted recent graduates who are largely unfamiliar with the use of occlusal adjustment by selective reshaping as a treatment modality. Use of proper occlusal therapy enables clinicians to more effectively help patients recover from parafunctional wear of the anterior and posterior teeth. In addition, familiarity with this field enhances the correction of progressive posterior and anterior reverse articulations. This article aims to highlight the importance of occlusal principles in treatment planning. In addition, we illustrate the benefits of occlusal adjustment by using a conservative technique, selective reshaping, as an option to correct anterior reverse articulation in a 20-year-old patient. The knowledge of occlusal principles enhances diagnosis of malocclusion in the development of a treatment plan. When properly employed, the technique of occlusal adjustment by selective reshaping may be used to correct an adaptive anterior reverse articulation with a high degree of predictability for select patients.

Anamorphic transformation and its application to time–bandwidth compression

A general method for compressing the modulation time-bandwidth product of analog signals is introduced. As one of its applications, this physics-based signal grooming, performed in the analog domain, allows a conventional digitizer to sample and digitize the analog signal with variable resolution. The net result is that frequency components that were beyond the digitizer bandwidth can now be captured and, at the same time, the total digital data size is reduced. This compression is lossless and is achieved through a feature selective reshaping of the signal's complex field, performed in the analog domain prior to sampling. Our method is inspired by operation of Fovea centralis in the human eye and by anamorphic transformation in visual arts. The proposed transform can also be performed in the digital domain as a data compression algorithm to alleviate the storage and transmission bottlenecks associated with "big data."

Patterning and encryption using gold nanoparticles

In this paper we describe a simple technique for the creation of patterns on different size scales and in a variety of substrates, based on the selective reshaping of Au nanorods into nanospheres. The drastic change in the optical properties of these materials when their shape is modified provides a sensitive and accurate tool for the creation of areas with different colours. Additionally, because the nanorods possess orientation-dependent optical response, the patterns can be selectively encoded or decoded by using polarised light.

Inside Front Cover: Optical Control and Patterning of Gold-Nanorod-Poly(vinyl alcohol) Nanocomposite Films (Adv. Funct. Mater. 7/2005)

The micropatterning of optical structures into thin films of poly (vinyl alcohol) (PVA) containing gold nanorods is demonstrated by Perez-Juste, Liz-Marzan, and co-workers on p. 1065. The nanorods are uniformly distributed in the thin films and can be aligned by stretching the films. The inside cover shows how irradiation with a nanosecond laser, using a TEM grid as mask, selectively reshapes the nanorods into nanospheres (upper and lower TEM images, respectively). Gold nanorods with well-defined aspect ratios are homogeneously incorporated within poly(vinyl alcohol) thin films and subsequently aligned by heating and stretching the nanocomposite films. The spatial alignment of the nanorods is directly proved using transmission electron microscopy. The polarization-dependent optical response of the rods is measured and compared with a dipole model. Excellent agreement is found. Additionally, irradiation of the film with nanosecond laser pulses (1064 nm) leads to selective reshaping of the nanorods into nanospheres, and we demonstrate that this effect can be used to micropattern optical structures into the films.
