摘要:
A process for preparing a particle comprising a biological molecule typically a DNA plasmid, and a carrier polymer, typically poly-lactic acid (PLA), in which an organic solvent solution of the biological molecule and the carrier polymer in an organic solvent medium, nearly saturated with the biological molecule, is prepared, then this solution is contacted with an antisolvent substance, typically supercritical carbon dioxide to separate a particle comprising the biological molecule and the carrier polymer. High loadings of the biological molecule in the particle can be achieved.

The invention relates to a roof box 1 for mounting to a vehicle. The roof box 1 includes a securing mechanism 10 that enables the top section 2 of the box 1 to be secured to the base section 3 of the box 1 via a single locking point and which urges the top section 2 from the base section 3 when the roof box 1 securing mechanism 10 is opened allowing the user access to lift the top section 2 open.

A leg assembly is described that links a roof rack bar to a vehicle roof. The leg assembly utilises a T-bar member linked to a rocker member and via a biasing arrangement, the T-bar flanges impinge with the bar flanges to lock the leg assembly in place or optionally move the leg assembly along the bar length by forcing the T-bar member flanges up from the bar flanges until the desired position is reached before release and re-locking.

An eddy-current braking mechanism including a rotor, rotatable about a rotor axis; at least one electrically conductive member coupled to the rotor for rotation therewith; at least one magnet configured to apply a magnetic field extending at least partially orthogonal to the plane of rotation of the conductive member, and characterised in that upon rotation of the rotor, the conductive member is configured to move at least partially radially from the rotor axis into the applied magnetic field.

A pixel design is disclosed. The pixel includes a photo-sensitive element. A first reflective layer substantially overlies the photo-sensitive element. A second reflective layer substantially underlies the photo-sensitive element and forms a cavity with the first reflective layer that is non-resonant with respect to photon absorption. An aperture is formed in either the first reflective layer or the second reflective layer. When electromagnetic radiation enters the aperture, the first reflective layer and the second reflective layer are configured to reflect the electromagnetic radiation substantially toward each other until substantially absorbed in the cavity.
摘要:
A non-linear conversion capability within an on-chip, per-column analog-to-digital converter (ADC) is provided to expand a compressed analog signal such that the resulting digital output that has a predetermined (linear or non-linear) mapping with respect to input brightness level of an incoming light signal to a row of pixels. The predetermined mapping may also be provided by a non-linear amplifier coupled to a linear or non-linear ADC and a resulting compressed non-linear digital representation at the output of the ADC is substantially linearized by an on-chip or an off-chip look-up table (LUT).

A method and apparatus for equalizing gain in an array of electron multiplication (EM) pixels is disclosed, each pixel having one or more impact ionization gain stages with implants to achieve charge transfer directionality and comprising a phase 1 clocked gate, an EM clocked gate, and two DC gates formed between the phase 1 clocked gate and the EM clocked gate, comprising the steps of (a) applying initial voltages to each of the DC gates and the EM clocked gates of at least two pixels of a plurality of pixels; (b) clocking phase 1 clock gates and an EM clock gates associated with the at least two pixels of the plurality of pixels a predetermined number of times to achieve an average pixel intensity value after impact ionization gain; and (c) selectively adjusting the difference in voltage between the DC gate and corresponding EM clocked gate of the at least two pixels of the plurality of pixels until the difference between the resulting pixel intensity values and the average pixel intensity value needed to produce a desired uniform gain image is below a predetermined threshold.

The present invention regards methods and formulations for diagnosis, prevention and treatment of disease. More particularly, the present invention teaches methods and formulations for diagnosis, prevention and treatment with antigen in autoimmune disease, allergy, rejection of transplants and cancer. Examples illustrate how the methods of formulations of the invention may be used for diagnosis and amelioration of autoimmune diabetes in which the 65kd isotype of glutamic acid decarboxylase (GAD) is a major antigen.

摘要:
A method for producing a colloid of metallic nanoparticles including the steps of: providing metal ions in solution; providing a stabilizing agent; and reducing said metal ions in the presence of said stabilizing agent, so that metallic nanoparticles are formed with a surrounding layer of said stabilizing agent, wherein the reduction step is carried out at a temperature of not less than 20° C. and not more than 150° C. The metallic nanoparticles are formed of a mixture of transition metal and noble metal, such as Ni—Pd. The resultant nanoparticles have a high stability in terms of size and chemical degradation and so can be stored for long periods. They are therefore particularly suited for forming patterned nanoparticle arrays on a substrate by nanocontact printing for the subsequent formation of a corresponding array of carbon nanotubes or nanofibers via plasma enhanced CVD.
