As part of MITRE’s work under the DARPA TIDES (Translingual Information Detection, Extraction and Summarization) program, we are preparing a series of demonstrations to showcase the TIDES Integrated Feasibility Experiment on Bio-Security (IFE-Bio). The current demonstration illustrates some of the resources that can be made available to analysts tasked with monitoring infectious disease outbrea...
Kisspeptin, encoded by Kiss1, stimulates GnRH neurons to govern reproduction. In rodents, estrogen-sensitive kisspeptin neurons in the anterior ventral periventricular nucleus and neighboring periventricular nucleus are thought to mediate sex steroid-induced positive feedback induction of the preovulatory LH surge. These kisspeptin neurons coexpress estrogen and progesterone receptors and displ...
This study aims at the effects of active immunization against chicken Vasoactive Intestinal Peptide (chVIP) on plasma prolactin (PRL) concentration, concentration of Luteinizing Hormone (LH) profile its interval and duration, progesterone (P ), estradiol (E ß), intersequence pause days and egg production in 4 2 birds during the initial stages of egg production from 20-36 weeks of egg lay in PB3...
Intertidal organisms may employ circatidal rhythms to track the tidal cycle, but tidal patterns may vary within a species range and necessitate adaptation to the local tides. Circatidal rhythms were examined in populations of the eastern Pacific fiddler crab Uca princeps (Smith) from four sites with differing tidal characteristics, La Paz (24 10¢N; 110 21¢W), San Blas (21 33¢N; 105 18¢W) and Ma...
We _consider t~e _tidal disturbance_ fo~c~d ~n a differentially rotating fluid by a rigidly rotating external potential. The flmd ~s assumed to be mviscid, msl:llated, and self-gravitating, and to have laminar unperturbed and pe~tu~bed velocity fields. The external potential may exert a steady torque on the fluid which is of second order m Its str~ngth. ~owever, to this. order, we prove that th...
Rapid eye movement (REM) sleep is characterized by periods of profound cardiac autonomic activation evident in heart rate surges in humans and canines. Our goals were to determine whether or not the heart rate surge phenomenon occurs in cats and to characterize concurrent central nervous system activity. Cortical and hippocampal electroencephalogram, electromyogram, electrooculogram, pontogenic...
[1] Previous studies have shown (1) that the Tibetan Plateau produces a significant fraction of the two components of the Equatorial Mountain Torque (EMT) in winter, (2) that these torques are in part related to the East Asian cold surges, and (3) that the cold surges affect the convection over the maritime continent. We show here that these relations are strong enough for the convection over t...
We analyzed simultaneous extreme-ultraviolet (EUV) data from the Transition Region and Coronal Explorer (TRACE) and H data from Big Bear Solar Observatory (BBSO). In the active region studied, we found several EUV jets which repeatedly occurred where pre-existing magnetic ux was \canceled" by newly emerging ux of opposite polarity. The jets look like Yohkoh soft X-ray jets, but are smaller and ...
