Heterologous prime/boost regimens have the potential for raising high levels of immune responses. Here, we report that DNA priming followed by a recombinant modified vaccinia Ankara (rMVA) booster has controlled a highly pathogenic immunodeficiency virus challenge in a Rhesus macaque model. Both the DNA and rMVA components of the vaccine expressed multiple immunodeficiency virus proteins. Two D...
Abstract Maternal Tdap vaccination during pregnancy is recommended to protect infants from pertussis, pre-vaccination. However, it unclear whether maternal immune responses improve following booster. We present analysis of pre- and post-Tdap booster, pregnant women (Pw) primed by whole cell vaccines, who received booster pregnancy, compared boosted non-pregnant (NPw). antigen specific serum ant...
A design criterion that permits truly omnidirectional reflectivity for all polarizations of incident light over a wide selectable range of frequencies was used in fabricating an all-dielectric omnidirectional reflector consisting of multilayer films. The reflector was simply constructed as a stack of nine alternating micrometer-thick layers of polystyrene and tellurium and demonstrates omnidire...
This paper investigates mechanisms of enhanced light absorption exhibited by ultrathin Si solar microcells integrated with a periodically nanostructured, semitransparent metallic reflector. This backside reflector comprises periodic nanoscale relief features formed by soft-imprint lithography with a thin (~35 nm) coating of Au. The work shows that microcells placed in direct contact above the n...
We report here the design of a new type of high efficiency grating coupler, based on single crystalline Si nanomembrane overlay and stacking. Such high efficiency diffractive grating couplers are designed for the purpose of coupling light between single mode fibres and nanophotonic waveguides, and for the coupling between multiple photonic interconnect layers for compact three-dimensional verti...
The far-field reflector problem is a well-known inverse problem arising in geometric optics. It consists in creating a mirror that reflects a given point light source to a prescribed target light at infinity. In this article, we study this problem under the common design constraint that the mirror is convex and is the graph of a polynomial over a given plane. We propose a method that iterativel...
This paper presents a proposal for a novel integrated tun-able coupler device called programmable coupler ladder, based on Titanium diffused lithium niobate waveguide and Y-junction reflector. Unlike the traditional serial to parallel converter, the coupler ladder sorts the output bits in the time axis using a built-in delay waveguide. With a proper control signal it can perform signal processi...
We propose a model-independent quantity, L/G, to characterize non-Gaussian tails in beam profiles observed with the Fermilab Booster Ion Profile Monitor. This quantity can be considered a measure of beam halo in the Booster. We use beam dynamics and detector simulations to demonstrate that L/G is superior to kurtosis as an experimental measurement of beam halo when realistic beam shapes, detect...
In a sample of originally 430 healthy adults (18-84 years of age) with documented basic and booster immunization against tick borne encephalitis, cumulative seroprotection rates 8 (n=178) and 10 years (n=183) after the last booster dose were 86.8% and 77.3% according to the neutralization test, respectively. In subjects aged 50 years and older, antibody titers were significantly lower compared ...
For booster vaccination of previously immunized persons with potential exposure to rabies, the World Health Organization recommends 2 doses of cell-culture vaccine administered intramuscularly or intradermally on days 0 and 3. We believe that four 0.1-mL intradermal booster doses given on a single day could be used at no risk to the recipient. We studied use of a single booster vaccination on d...
