MIL-STD-1553 is a military standard that defines the physical and logical layers, and a command/response time division multiplexing of a communication bus used in military and aerospace avionic platforms for more than 40 years. As a legacy platform, MIL-STD-1553 was designed for high level of fault tolerance while less attention was taken with regard to security. Recent studies already addresse...

In a modern military avionics system all the devices need to communicate as efficiently as possible with a minimum amount of hardware. 1553 is a dualredundant, bi-directional, Manchester encoded, digital time division command/ response data bus which eliminates the use of point-to-point wiring. It uses a shielded twisted pair wire for data transfer. This bus can allow communication between any ...

RATIONALE Stable analogs of vasoactive intestinal peptide (VIP) have been proposed as novel line of therapy in chronic obstructive pulmonary disease (COPD) based on their bronchodilatory and anti-inflammatory effects. We speculated that VIP analogs may provide additional benefits in that they exert vasodilatory properties in the lung, and tested this hypothesis in both ex vivo and in vivo model...

BACKGROUND The synthetic vasoactive intestinal peptide (VIP) analogue Ro 25-1553 is a selective VIP-PACAP type 2 (VPAC(2)) receptor agonist that causes a bronchodilatory effect in guinea pigs in vivo. The effect of Ro 25-1553 given by inhalation to patients with asthma was studied and compared with that of a long acting beta(2) adrenoceptor agonist. METHODS Twenty four patients with moderate ...

MAP3K1 is a serine/threonine kinase that is activated by a diverse set of stimuli and exerts its effect through various downstream effecter molecules, including JNK, ERK1/2 and p38. In humans, mutant alleles of MAP3K1 are associated with 46,XY sex reversal. Until recently, the only phenotype observed inMap3k1 mutant mice was open eyelids at birth. Here, we report that homozygous Map3k1 mice hav...

VMEbus Systems / August 2005 MIL-STD-1553 is a serial, time-division multiplex data bus that has been used as the primary command and control data interconnect in military aircraft for the past three decades. MIL-STD1553’s robust performance, high level of interoperability, large installed base, and well established infrastructure of vendors has made it the network of choice for military avioni...

Two kinds of systems will be described. The first is based on non-diffraction limited cat's eyes using telecentric lenses. These systems were used to implement a short-range optical link (3 meters) that was inserted into a standard 1553 protocol network. We will describe the optical design and the MQW photonic back-plane. We will also discuss a demonstration of a 4 node 1553 network using these...
