A well-functioning brain requires production of the correct number and types of cells during development; cascades of transcription factors are essential for cellular coordination. Sox proteins are transcription factors that affect various processes in the development of the nervous system. Sox11, a member of the SoxC family, is expressed in differentiated neurons and supports neuronal differen...
Neurogenic placodes, a chordate innovation, generate several neuronal populations, including gonadotropin-releasing hormone (GnRH) neurons which are crucial for vertebrate and solitary ascidian urochordate reproduction. The dorsal strand placode of ascidians Is derived from the anterior ridge of the embryonic neural plate and thus shares a common developmental origin and expression of various t...
We consider flow in a Hele–Shaw cell for which the upper plate is being lifted uniformly at a specified rate. This lifting puts the fluid under a lateral straining flow, sucking in the interface and causing it to buckle. The resulting short-lived patterns can resemble a network of connections with triple junctions. The basic instability—a variant of the Saffman–Taylor instability—is found in a ...
Beginning with a genetically heterogeneous outbred stock of mice (Binghamton HET), selective breeding was conducted within two selected lines for a high analgesic (antinociceptive) response and a low analgesic response, respectively, to a narcotic analgesic (Ievorphanol tartrate) using the hot-plate test. A nonselected control line was also maintained concurrently. Four generations of predomina...
Particle pulses generated by laser-plasma interaction are characterized by ultrashort duration, high particle density, and sometimes a very strong accompanying electromagnetic pulse (EMP). Therefore, beam diagnostics different from those known from classical particle accelerators such as synchrotrons or linacs are required. Easy to use single-shot techniques are favored, which must be insensiti...
A radial wettable gradient was fabricated on the surface of graphite plate by a simple one-step anodic oxidation process. It was found that the direction and value of the wettable gradient could be easily controlled by adjusting current and oxidation time gradient. With the increase of surface temperature, droplets on surface not only exhibited the transition of boiling mode, but also showed th...
Variability in growth rate was observed among S strain isolates of Aspergillus flavus from western Arizona. Isolates were grouped into fast and slow growing biotypes and compared for radial growth, and sclerotia, spore, aflatoxin, and pectinase production. Slow and fast biotypes were distributed equally among three collection areas with 35% of 300 S strain isolates classified as the slow biotyp...
Recent work by Jaffe and Scardicchio has expressed the optical approximation to the Casimir effect as a sum over geometric quantities. The first two authors have developed a technique which uses the complex geometry of the space of oriented affine lines in R to describe reflection of rays off a surface. This allows the quantities in the optical approximation to the Casimir effect to be calculat...
