The overlay of an intelligent Frequency Diversity Spread Spectrum System (FDSS) on the Advanced Mobile Phone Service system (AMPS) is studied. The worst-case condition is considered for the downlink analysis. Moreover, the effect of sidelobes outside the FDSS principal spectrum is considered. The downlink and uplink capacity of both systems are given using a model of 25 cells. Results show that...

 Researchers in the field of simulation have been mainly interested in the question of how to increase the efficiency of solar cells. Therefore this study aimed to investigate CdS/CdTe solar cells by applying AMPS-1D software. The impact of semiconductor layers thickness on the output parameters of the CdS/CdTe solar cell is being analyzed and studied carefully, for example, fill factor, effici...

Cationic antimicrobial peptides (AMPs) are an intrinsic part of the human innate immune system. Over 100 different human AMPs are known to exhibit broad-spectrum antibacterial activity. Because of the increased frequency of resistance to conventional antibiotics there is an interest in developing AMPs as an alternative antibacterial therapy. Several cationic peptides that are derivatives of AMP...

Cationic antimicrobial peptides (AMPs) became a promising alternative to the conventional cancer drugs. We investigated the effects of 5 AMPs (melittin, galanin-mastoparan, cecropins A, B and P1) on the viability of HT-29 and AR-42J carcinoma cells. The viability of the cells was evaluated and used to calculate the AMPs therapeutic index. Also, cellular apoptosis and necrosis were analyzed. Mel...

The concept of antimicrobial peptides (AMPs) as potent pharmaceuticals is firmly established in the literature, and most research articles on this topic conclude by stating that AMPs represent promising therapeutic agents against bacterial and fungal pathogens. Indeed, early research in this field showed that AMPs were diverse in nature, had high activities with low minimal inhibitory concentra...

26 Host defense antimicrobial peptides (AMPs) are a promising source of antibiotics for the 27 treatment of multiple drug-resistant pathogens. Lipopolysaccharide (LPS), the major 28 component of the outer leaflet of the outer membrane of Gram-negative bacteria, functions as 29 a permeability barrier against a variety of molecules including antimicrobial peptides (AMPs). 30 Further, LPS or endot...

Polymeric synthetic mimics of antimicrobial peptides (SMAMPs) have recently demonstrated similar antimicrobial activity as natural antimicrobial peptides (AMPs) from innate immunity. This is surprising, since polymeric SMAMPs are heterogeneous in terms of chemical structure (random sequence) and conformation (random coil), in contrast to defined amino acid sequence and intrinsic secondary struc...

This study concerns an attempt to establish a new method for predicting antimicrobial peptides (AMPs) which are important to the immune system. Recently, researchers are interested in designing alternative drugs based on AMPs because they have found that a large number of bacterial strains have become resistant to available antibiotics. However, researchers have encountered obstacles in the AMP...

Antimicrobial peptides (AMPs) are small defense proteins present in various organisms. Major groups of AMPs include beta-barrelin, hevein, knottin, lipid transfer protein (LTP), thionin, defensin, snakin, and cyclotide. Most plant AMPs involve host plant resistance to pathogens such as fungi, viruses, and bacteria, whereas a few plant AMPs from the cyclotide family carry insecticidal functions....

Motivation: The increased prevalence of multi-drug resistant (MDR) pathogens heightens the need to design new antimicrobial agents. Antimicrobial peptides (AMPs) exhibit broad-spectrum potent activity against MDR pathogens and kills rapidly, thus giving rise to AMPs being recognized as a potential substitute for conventional antibiotics. Designing new AMPs using current in-silico approaches is,...
