Do you have a favorite scientific journal? Although I have several favorites which illuminate my life, I am particularly fond of Cat News, a quarterly newsletter edited by noted conservationist Peter Jackson of IUCN. Cat News publishes short essays about new developments relating to non-domestic wild cat species, from lynxes to tigers to lions and snow leopards. Felid observations, conservation...

abstract a previous study on agricultural drains in khuzestan province of iran has indicated that carbonate calcium is the main component of the deposited salts in drainage envelops. to investigate the process of precipitation of carbonate calcium under different conditions including chemical, bio-chemical, aerobic and an-aerobic, a through laboratory investigation on geotextile drain envelop w...

Similarity Indexing is very important for content-based retrieval on large multimedia databases, and the "tightness" of data set envelope is a factor that influences the performance of index. For equidistant envelope (bounding sphere), calculation of envelope is somewhat difficult because of the complexity of direct computation in high dimension space. In this paper we summarize the envelope us...

Nesprins (nuclear envelope spectrin repeat proteins), also known as SYNE (synaptic nuclear envelope protein), MYNE (myocyte nuclear envelope protein), ENAPTIN and NUANCE, are proteins that are primarily components of the nuclear envelope. The nuclear envelope is a continuous membrane system composed of two lipid bilayers: an inner and an outer nuclear membrane. Nesprins are components of both n...

Abstract A number of studies have explored how speech envelope and temporal fine structure (TFS) cues contribute to speech perception. Some recent investigations have attempted to process speech signals to remove envelope cues and leave only TFS cues, but the results are confounded by the fact that envelope cues may be partially reconstructed when TFS signals pass through the narrowband filters...

At high frequencies, interaural time differences (ITDs) are conveyed by the sound envelope. Sensitivity to envelope ITDs depends crucially on the envelope shape. Reverberation degrades the envelope shape, reducing the modulation depth of the envelope and the slope of its flanks. Reverberation also reduces the envelope interaural coherence (i.e., the similarity of the envelopes at two ears). The...

The chlorophyll precursors protochlorophyllide and chlorophyllide were identified in purified envelope membranes from spinach (Spinacia oleracea) chloroplasts. This was shown after pigment separation by high performance liquid chromatography (HPLC) using specific fluorescence detection for these compounds. Protochlorophyllide and chlorophyllide concentrations in envelope membranes were in the r...

The nuclear envelope consists of 2 membranes separated by 30-50 nm, but how the 2 membranes are evenly spaced has been an open question in the field. Nuclear envelope bridges composed of inner nuclear membrane SUN proteins and outer nuclear membrane KASH proteins have been proposed to set and regulate nuclear envelope spacing. We tested this hypothesis directly by examining nuclear envelope spa...
