Despite the spread of multimedia applications, voice will still account for most of the overall traffic in telecommunications networks in the near future, as it did in the past. For this kind of traffic it has been observed that if one ATM VCC is assigned to only one source, too high delays to fill the whole 48-byte ATM-cell payload, or high bandwidth wastes if an ATM cell is partially assigned...

An icosahedral closo-B₁₂²⁻ scaffold based nano-sized assembly capable of carrying a high payload of Gd³⁺-chelates in a sterically crowded configuration is developed by employing the azide-alkyne click reaction. The twelve copies of DO3A-t-Bu-ester ligands were covalently attached to an icosahedral closo-B₁₂²⁻ core via suitable linkers through click reaction. This nanomolecular structure support...

Evaluation of the performance of electro-optical payload within the laboratory is discussed. This method is valid for the system, which has output in the form of electrical signal though the input is optical in nature. The methodology enables the evaluation of entire configuration of electro-optical payload comprising of lens system, photo detecting device (one or two dimension array) and proce...

A novel optical layer performance monitoring method in transparent optical-label switching networks is presented. It is based on the signal quality correlation between the data payload and the label, which allows monitoring of the data payload signal quality by monitoring the label bit error rates. Experimental results indicate effective estimations of payload data bit error rates over approxim...

The payload increase of watermarking channels via the use of low-density parity check codes is considered. The bit error rate and payload size problem is addressed in the light of the performance of typical transform-domain spread-spectrum watermarking techniques. Simulation results indicate that the information payload can be doubled via judicious use of LDPC codes vis-à-vis the performance of...

The integration of biomedical sensors with wireless network technology may have great potentials in medical applications. In this paper, we investigate the use of the IEEE 802.15.4 standard in an ECG monitoring sensor network and study the effects of CSMA/CA mechanism, number of network devices, sampling rates and transmitting cycles. The performance of the network is analyzed in terms of trans...

Purpose Radiolabeled antibodies and peptides hold promise for molecular radiotherapy but are often limited by a low payload resulting in inadequate delivery of radioactivity to tumour tissue and, therefore, modest therapeutic effect. We developed a facile synthetic method of radiolabeling indium-111 (111In) to epidermal growth factor (EGF)-gold nanoparticles (111In-EGF-Au NP) with a high payloa...

The LAPLAS experimental scheme (beam-target geometry) is shown in Fig. 1. It is a multi-layered target that consists of s solid cylinder of frozen hydrogen that is enclosed in a cylindrical shell of a high-Z material like Pb or Au. One face of this target is irradiated with an intense ion beam that has an annular focal spot whose dimensions are chosen in such a way that the hydrogen is not dire...
