We suggest a definition for a type of chimera state that appears in networks of indistinguishable phase oscillators. Defining a "weak chimera" as a type of invariant set showing partial frequency synchronization, we show that this means they cannot appear in phase oscillator networks that are either globally coupled or too small. We exhibit various networks of four, six, and ten indistinguishab...

Chimera states are surprising spatiotemporal patterns in which regions of coherence and incoherence coexist. Initially observed numerically, these mathematical oddities were recently reproduced in a laboratory setting, sparking a flurry of interest in their properties. Here we use asymptotic methods to derive the conditions under which two-dimensional "spot" and "stripe" chimeras (similar to th...

The authentication of the navigation signals can be considered as contribution system to robustness against spoofing attacks and it is becoming an important requirement for a growing number user communities. GPS Galileo systems are proposing evolutions their civil embed features authentication. For Galileo, Open Service Navigation Message Authentication (OSNMA) integrated in E1 OS signal. GPS, ...

Journal of Futures Studies, February 2007, 11(3): 47 60 H.G. Well's novel The Island of Dr. Moreau (1896) is based on a brilliant but mad scientist who explores the "plasticity of life" via recombinant human and non-human DNA (Brem and Amjar, 2003). While the consequential chimera (transgenics) are endowed with human reason their proclivity towards reverting to their previous "animal" selves re...

The angiotensin II type 2 (AT(2)) receptor is expressed in bone marrow cells and may affect cell differentiation. We previously reported a beneficial role of the AT(2) receptor in ischemic brain damage. Here, we investigated the effect of AT(2) receptor stimulation in hematopoietic cells on ischemic brain injury using chimeric mice. Chimeric mice were generated by bone marrow transplantation in...

Chimera states have attracted significant attention as symmetry-broken exhibiting the unexpected coexistence of coherence and incoherence. Despite valuable insights gained from analyzing specific systems, an understanding general physical mechanism underlying emergence chimeras is still lacking. Here, we show that many stable arise because in part system sustained by incoherence rest system. Th...

CHIMERA is a multi-dimensional radiation hydrodynamics code designed to study core-collapse supernovae. The code is made up of three essentially independent parts: hydrodynamics, nuclear burning, and a neutrino transport solver combined within an operator-split approach. The multi-physics nature of the problem, and the specific implementation of that physics in CHIMERA, provide a rather straigh...

It has been shown that covalently linking two antigens could enhance the immunogenicity of the chimeric construct. To prioritize such a chimera for malaria vaccine development, it is necessary to demonstrate that naturally acquired antibodies against the chimera are associated with protection from malaria. Here, we probe the ability of a chimeric construct of UB05 and UB09 antigens (UB05-09) to...

Integrating access to web services with desktop applications allows for an expanded set of application features, including performing computationally intensive tasks and convenient searches of databases. We describe how we have enhanced UCSF Chimera (http://www.rbvi.ucsf.edu/chimera/), a program for the interactive visualization and analysis of molecular structures and related data, through the...

Development of fusion chimeras as potential vaccine candidates is considered as an attractive strategy to generate effective immune responses to more than one antigen using a single construct. Here, we described the design, production, purification and antigenicity of a fusion chimera (PfAMSP-Fu35), comprised of immunologically relevant regions of three vaccine target malaria antigens, PfAARP, ...
