This paper presents a radio-frequency (RF) antenna as sensor to detect Horseradish peroxidase (HRP). At the core of proposed approach is graphene film deposited on stub connected an RF antenna. The doctor bladed stub. then properly chemically functionalized in order presence We validate proof-of-concept operation HRP concentration detection by measuring frequency shift reflection coefficient us...

1. Introduction Leaky-wave antennas based on an open-waveguide structure without partly physical cut become a candidate of millimeter-wave antennas because asymmetry of the structure can easily produce a radiation along its length due to a leaky mode. One of these open waveguides for antenna purposes is the stub-loaded ridge-rectangular waveguide, which consists of a ridge-rectangular waveguide...

Interconnection across administrative boundaries prompts the need for comprehensive policy enforcement (i.e., access control) with respect to inter-domain packet traac. Due to the nature of the communication services they provide, stub and transit domains require diierent mechanisms for policing inter-domain traac. This paper addresses the design of a policy enforcement mechanism geared speciic...

background: sentinel  lymph  node  biopsy  has  shown  to  be  a  good  alternative procedure  for  axillary  lymph  node  dissection  and  to lead  to  lower  frequency  of morbidity, though this technique has its own side effects. it needs especial equipment and may not be available in some medical centers, especially in developing countries. this study aimed to identify a subgroup of patient...

This paper introduces a design method of simple bandpass (BP) negative group delay (NGD) topology. The fundamental specifications BP NGD function are defined. passive topology consists parallel resistance associated with an open-ended microstrip stub. properties and characterization respect to the constituting stub parameters established. validations performed theoretical calculated simulated G...

Internet disruptions such as the Northeast Blackout (2003) and the Taiwan earthquake (2006) highlight the fragility of today’s Internet. Our goal in this paper is to investigate the robustness of inter-domain communication at the level of autonomous systems (ASes), taking into account both topological connectivity and compliance to routing policies. To this end, we introduce the concept of k-fa...

In this paper we present Three-Valued Spatio-Temporal Logic (TSTL), which enriches the available spatio-temporal analysis of properties expressed in Signal Spatio-Temporal Logic (SSTL), to give further insight into the dynamic behaviour of systems. Our novel analysis starts from the estimation of satisfaction probabilities of given SSTL properties and allows the analysis of their temporal and s...

The Singwi, Sjölander, Tosi, Land (SSTL) approach is generalized to study the spin–correlation effects in a one dimensional electron gas. It is shown that the SSTL approach is capable of generating results comparable to the more widely used STLS approach. e-mail: [email protected] e-mail: [email protected]
