An L-vertex, the point at which two contours coterminate, provides highly reliable evidence that a surface terminates at that vertex, thus providing the strongest constraint on the extraction of shape from images (Guzman, 1968). Such vertices are pervasive in our visual world but the importance of a statistical regularity about them has been underappreciated: The contours defining the vertex ar...

Abstract Flexible and stretchable electronics present opportunities for transition from rigid bulky devices to soft conformal systems. However, such technology requires mechanical design integration strategies enhance robustness form factor. In addition, scalable reliable fabrication pathways are needed facilitate the high volume manufacturing required satisfy a growing market demand. This repo...

Abstract Low‐dimensional microwave interconnects have important applications for nanoscale electronics, from complementary metal–oxide‐semiconductor (CMOS) to silicon quantum technologies. Graphene is naturally and has already demonstrated attractive electronic properties, however its application electronics limited by available fabrication techniques CMOS incompatibility. Here, the characteris...

Abstract The continued progress in electronics technology has led to unsustainable consumption of plastic-based products containing, their majority, natural finite metallic resources. substitution these plastic materials by more sustainable ones, such as cellulosic substrates, is one many measures applied the industry reduce environmental i mpact. In this work, due lack information literature, ...

purpose: the distinction between the concepts of science and technology has made it necessary for economic and scientific policymakers to know the realms of these two areas. the relationship between the science and the technology is changing and also is variable depending on the circumstances, scientific areas, and from one time to another one. the current research aims at studying the growth t...

background and aims. digital imaging continues to gain acceptance in dentistry and video display used for this becomes important. the aim of this study was to assess the influence of the display monitor on observer performance on caries detection. materials and methods. artificial enamel lesions were created in 40 extracted teeth at random using 1/4 and 1/2 round burs. teeth were mounted in den...

The automotive industry is experiencing a remarkable move from the internal combustion engine (ICE) to an all-electric power platform. This natural shift essentially supported by electric drive development where wide-bandgap (WBG) materials are at center of this transformation. gallium nitride (GaN)- or silicon carbide (SiC)-based electronics taking place due theoretical limits Si MOSFETs that ...

The DC microgrid is an effective architecture that is utilized to achieve reliable power with high efficiency through the implementation of power electronics converters and energy storage devices. Many systems are currently using DC power. For instance, DC architecture is employed in data centers to provide efficient and reliable power distribution across large numbers of electrical loads. The ...

The fabrication of nanowire (NW) devices on diverse substrates is necessary for applications such as flexible electronics, conformable sensors, and transparent solar cells. Although NWs have been fabricated on plastic and glass by lithographic methods, the choice of device substrates is severely limited by the lithographic process temperature and substrate properties. Here we report three new t...

Wafer-scale fabrication of complex nanofluidic systems with integrated electronics is essential to realizing ubiquitous, compact, reliable, high-sensitivity and low-cost biomolecular sensors. Here we report a scalable fabrication strategy capable of producing nanofluidic chips with complex designs and down to single-digit nanometre dimensions over 200 mm wafer scale. Compatible with semiconduct...
