Effective monitoring programs for biodiversity are needed to assess trends in biodiversity and evaluate the consequences of management. This is particularly true for birds and faunas that occupy interior forest and other areas of low human population density, as these are frequently under-sampled compared to other habitats. For birds, Autonomous Recording Units (ARUs) have been proposed as a su...

The members of the voltage-dependent potassium channel family subserve a variety of functions and are expected to have voltage sensors with different sensitivities. The Shaker channel of Drosophila, which underlies a transient potassium current, has a high voltage sensitivity that is conferred by a large gating charge movement, approximately 13 elementary charges. A Shaker subunit's primary vol...

Atomic recovery units (ARUs) are a mechanism that allows several logical disk operations to be executed as a single atomic unit with respect to failures. For example, ARUs can be used during file creation to update several pieces of file meta-data atomically. ARUs simplify file systems, as they isolate issues of atomicity within the logical disk system. ARUs are designed as part of the Logical ...

—We evaluated an automated telemetry system that can dramatically increase the amount of activity and spatial data collected for snakes. We developed methods for analyzing data from single automated receiving units (ARUs) and ARU arrays, compared results from ARUs with conventional hand tracking, and assessed previously untested assumptions used in conventional telemetry, using data from ratsna...

al-shab al-zarif, one of the most well-known poets of decadence age, is also a foremost borrower of religious texts in the field of worldly lyric. his lyrics are influence by quran, various religious texts, and notions of his sufi father, afif al-din telmesani. this study tries to examine the works of this prominent poet and analyze their intersexual relations to show his power in mixing religi...

Determining the contribution of a single type of ion channel to information processing within a neuron requires not only knowledge of the properties of the channel but also understanding of its function within a complex system. We studied the contribution of slow delayed rectifier K+ channels to neural coding in Drosophila photoreceptors by combining genetic and electrophysiological approaches ...

Regulation of synaptic efficacy by nerve terminal excitability has not been extensively studied. We performed genetic and pharmacological dissections for presynaptic actions of K+ channels in Drosophila neuromuscular transmission by using electrophysiological and optical imaging techniques. Current understanding of the roles of the Shab IK channel and its mammalian Kv2 counterparts is relativel...

The delayed rectifier K+ current in Drosophila is similar to the classical delayed rectifier, originally described by Hodgkin and Huxley. Drosophila provides unique tools of mutant analysis to unambiguously determine the genetic identity of this native K+ current. We identified the Shab gene as the exclusive gene underlying delayed rectifier currents in both muscle and neurons. In muscles, a ge...
