Abstract A series of polyimide (PI)/SiO 2 aerogel microspheres were prepared by using polyamide acid salt and hydrolyzed tetraethyl orthosilicate based on the reverse-phase emulsion method. Then, PI/SiO carbonized etched to obtain carbon (CAMs). Scanning electron microscope, transmission microscope nitrogen isothermal adsorption used characterize micro-morphology pore structure microspheres; el...

Cavity array metamaterials (CAMs), composed of optical microcavities in a lattice coupled via tight-binding interactions, represent a novel architecture for engineering metamaterials. Since the size of the CAMs' constituent elements are commensurate with the operating wavelength of the device, it cannot directly utilise classical transformation optics in the same way as traditional metamaterial...

In this paper we present an optical approach for managing an index to a very large data/knowledge base. Specifically, our research is focused on optical content addressable memories (OCAM) based on holographic principles. OCAMs offer advantages over conventional CAMs in managing a large index, because OCAMs offer a considerably larger storage~ capacity (1O8~1Ob0 bytes) and parallel output. With...

Direct Device-to-Device (D2D) communications underlaying the cellular network are receiving increasing attention lately: LTE-A standard will adopt them for unicast proximity services. So far, no application has been envisioned for broadcast transmissions. In this work, we propose an eMBMSinspired mechanism to allocate a quasi-static pool of resources over multiple eNodeBs (eNBs) for D2D broadca...

Abstract. We present the Copernicus Atmosphere Monitoring Service TEMPOral profiles (CAMS-TEMPO), a dataset of global and European emission temporal that provides gridded monthly, daily, weekly hourly weight factors for atmospheric chemistry modelling. CAMS-TEMPO includes priority air pollutants (NOx; SOx; NMVOC, non-methane volatile organic compound; NH3; CO; PM10; PM2.5) greenhouse gases (CO2...

Abstract Belief systems matter for all kinds of human social interaction. People have individual cognitions and feelings concerning processes in their environment, which is why they may evaluate them differently. can be visualized with cognitive-affective maps (CAMs; as reported by Thagard (in: McGregor (ed) EMPATHICA: A computer support system visual representations mapping, AAAI Press, CA, 20...

The shape of the cams used in rock climbing friends is derived using a linear system of differential equations.

Weakly supervised semantic segmentation with only image-level labels aims to reduce annotation costs for the task. Existing approaches generally leverage class activation maps (CAMs) locate object regions pseudo label generation. However, CAMs can discover most discriminative parts of objects, thus leading inferior pixel-level labels. To address this issue, we propose a saliency guided I...
