Application Note 1313 2 The demand for ubiquitous wireless communications is challenging the physical constraints placed upon current wireless communications systems. In addition, wireless customers expect wireline quality from their service providers. Service providers have invested a lot in a very limited slice of the radio spectrum. Consequently, network equipment manufacturers must produce ...
Nine bowhead whales (Balaena mysticetus) were instrumented with satellite transmitters in West Greenland in May 2002 and 2003. Transmitters were either encased in steel cans or imbedded in floats attached to wires. Transmitters mounted in steel cans had a high initial failure rate, yet those that were successful provided tracking durations up to seven months. Float tags had a low initial failur...
We consider the problem of Simultaneous Wireless Information and Power Transfer (SWIPT) over a fading multiple access channel with additive Gaussian noise. The transmitters as well as the receiver harvest energy from ambient sources. We assume that the transmitters have two classes of data to send, viz. delay sensitive and delay tolerant data. Each transmitter sends the delay sensitive data at ...
It is not yet understood how the molecular mechanisms controlling the release of neuropeptides differ from those controlling the release of classical transmitters, mainly because there are few peptidergic synapses in which the environment at the presynaptic release sites can be manipulated. Using Aplysia californica neuron B2, which synthesizes both peptide and classical transmitters, we have e...
one of the recent inquiries in the field of hadith studies is the investigation of transferred traditions and their causes and impacts on shi‘i hadith circles. by exploring some traditions in the hadith collection of al-shaykh al-saduq and comparing the textual similarities and also the chain of transmitters, this research attempts to show that traditions of jewish origin in the shi‘i hadith ci...
sezgin argued that written documents were used from early on and although collectors transmitted their works orally but extracted hadiths from written sources. according to him the isnads contain the name of authors and the authoritative transmitters of the books. also he proposed a method based on isnad analysis to single out the sources of a collector and to reconstruct the early lost works. ...
Mountain ranges, deserts, ice fields and oceans generally act as barriers to the movement of land-dependent animals, often profoundly shaping migration routes. We used satellite telemetry to track the southward flights of bar-tailed godwits (Limosa lapponica baueri), shorebirds whose breeding and non-breeding areas are separated by the vast central Pacific Ocean. Seven females with surgically i...
