The transcription of the immediate-early genes Arc and Homer 1a (H1a) is dynamically regulated in response to synaptic activity; their protein products function at the postsynaptic sites of excitatory synapses. Previous studies demonstrate a role for Arc in the maintenance of long-term potentiation and in memory consolidation processes and indicate a role for H1a in modifying glutamatergic sign...

We examine the size s(n) of a smallest tournament having the arcs of an acyclic tournament on n vertices as a minimum feedback arc set. Using an integer linear programming formulation we obtain lower bounds s(n) ≥ 3n − 2 − blog2 nc or s(n) ≥ 3n − 1 − blog2 nc, depending on the binary expansion of n. When n = 2k − 2t we show that the bounds are tight with s(n) = 3n−2−blog2 nc. One view of this p...

Ground-based synthetic aperture radar (GB-SAR) has become an important technique for remote sensing deformation monitoring. However, most of the existing GB-SAR systems realize synthetic aperture by exploiting two closely spaced horn antennas to move along a linear rail. In order to obtain higher data acquisition efficiency and a wider view angle, we introduce arc antenna array technology into ...

One approach to study moduli spaces is to use arcs. Taking this approach, we defined the arc operad, which among other things models correlation functions on over a certain partial compactification of moduli space. Using a careful analysis, we then were able to restrict the theory to moduli space and to extend it to the open/closed case. An example of these correlation functions are actions on ...

The mosquito’s nuisance becomes major problems in the metropolitan cities in India now days. The endemic situation of vector borne diseases (VBDs) and the sporadic of such diseases, known as, malaria, filariasis, JE, dengue and chikungunya have been most important challenging problems in the urban settlements now days in India. The Arc View 3.2, Arc View Spatial analysis and Arc View image anal...

Many visual experiments call for visual displays in which dots are plotted with very fine positional accuracy. Spatial hyperacuities and motion displacement thresholds can be as low as 5 sec arc. On computer graphics displays small angular displacements of a pixel can be obtained only with long viewing distances which impose a small field of view. To overcome this problem, we describe a method ...

In a PV system, DC arc is regarded as a serious fault, which might cause circuit damage and trigger fires. The arc fault, however, is hard to detect due to the special fields of photovoltaic systems: constant direct current without zerocrossing point, sophisticated components leading to noise interruption, and usually occupying large area. Therefore, detectable characteristics are of great impo...

The silicide Sc2RuSi2 was synthesized from the elements by arc-melting. The structure was refined on the basis of single crystal X-ray diffractometer data: Sc2CoSi2 type, * Manuscript Click here to view linked References

[1] We report the first observations of E region neutral wind fields and their interaction with auroral arcs at mesoscale spatial resolution during geomagnetically quiet conditions at Mawson, Antarctica. This was achieved by using a scanning Doppler imager, which can observe thermospheric neutral line‐of‐sight winds and temperatures simultaneously over a wide field of view. In two cases, the ba...
