For over a centmy, Dyke marsh along the Potomac River just south of Alexandria, VA, has been a favorite site for natural history studies. Despite earlier attempts at diking to create agricultural land and dredging for sand and gravel, the remaining marsh represents the last major tidal freshwater wetland on the upper Potomac River, and is now owned and maintained by the National Park Seivice as...

the right side. All the findings favoured diagnosis of Dyke David -Masson syndrome. Significant contrasting feature in our patient than the patient described in the journal was the presence of left sided cerebellar atrophy (Figure 1). DykeDavidoff-Masson syndrome associated with crossed cerebellar atrophy (CCA) has been previously described in some pat ients . There are two schools of thought r...

This contribution describes maps of the Copper Cliff Embayment (CCE) and Offset (CCO) dyke. The associated study attempts to unravel mode melt emplacement role pre-impact faults in deformation southern part Sudbury Igneous Complex (SIC). summarizes field observations (maps images) structural measurements. In addition, perspective views 3D Move model CCE CCO dyke are provided. data can be used b...

In swarm robotics, the agents are often assumed to be identical. In this paper, we argue that the cooperation between swarms of different kinds of robots can enhance the capabilities of the robotic system — heterogeneous swarms marry the robustness and parallelism of homogeneous swarms with efficient task specialisation. A key problem of heterogeneous swarm systems is the potential complexity o...

Introduction: Metadolerite dykes in the Western Dharwar Craton represent oldest generation of mafic dyke swarms craton. The emplacement these after a period crust building activity and komatiite volcanism, helps to understand evolution Subcontinental Lithospheric Mantle (SCLM) Archean dynamics. Methods: We report whole rock major, trace element geochemistry Sr-Nd isotope characteristics for thi...

We present a model of soft active particles that leads to a rich array of collective behavior found also in dense biological swarms of bacteria and other unicellular organisms. Our model uses only local interactions, such as Vicsek-type nearest-neighbor alignment, short-range repulsion, and a local boundary term. Changing the relative strength of these interactions leads to migrating swarms, ro...

Dyke-Davidoff-Masson syndrome (DDMS) is a rare, but important cause of drug-resistant seizures. Dyke-Davidoff-Masson syndrome is a constellation of clinical features that consists of hemiparesis, seizure, facial asymmetry, and intellectual disability with distinct neuroimaging features. A 27-year-old lady presented to us with drug-resistant epilepsy, hemiparesis, and intellectual disability tha...

Observations of the relationship between linear or planar features on either side of dykes usually form the basis of a field determination of their mode of emplacement, although it is known that sections oblique to planar features may lead to conflicting results. In Eastern Tasmania only rarely are examples encountered where dyke wall-rock units are of use. However, dyke wall irregularities are...

Background: Malaria mosquitoes form mating swarms around sunset, often at the same locations for months or years. Unfortunately, studies of Anopheles swarms are rare in East Africa, the last recorded field observations in Tanzania having been in 1983. Methods: Mosquito swarms were surveyed by trained volunteers between August-2016 and June-2017 in Ulanga district, Tanzania. Identified Anopheles...
