Abstract: Various examples of reprogrammable universal logic devices are provided. In one example, the device can include a tunable AC input to an oscillator/resonator; a first logic input and a second logic input to the oscillator/resonator, the first and second logic inputs provided by separate DC voltage sources (VA, VB), each of the first and second logic inputs including an on/off switch (A, B); and the oscillator/resonator including an output terminal. The tunable oscillator/resonator can be a MEMS/NEMS resonator. Switching of one or both of the first or second logic inputs on or off in association with the tuning of the AC input can provide logic gate operation. The device can easily be extended to a 3-bit or n-bit device by providing additional logic inputs. Binary comparators and encoders can be implemented using a plurality of oscillators/resonators.

Abstract: Embodiments of a tunable bandpass microelectromechanical (MEMS) filter are described. In one embodiment, such a filter includes a pair of arch beam microresonators, and a pair of voltage sources electrically coupled to apply a pair of adjustable voltage biases across respective ones of the pair of arch beam microresonators. The pair of voltage sources offer independent tuning of the bandwidth of the filter. Based on the structure and arrangement of the filter, it can be tunable by 125% or more by adjustment of the adjustable voltage bias. The filter also has a relatively low bandwidth distortion, can exhibit less than 2.5 dB passband ripple, and can exhibit sideband rejection in the range of at least 26 dB.

In particular, the invention relates to a conjugate comprising a first portion connected to a second portion, wherein the first portion binds to an MHC Class I molecule and the second portion has HLA-G activity. This conjugate may be used as a medicament to modulate immune responses and induce immunological tolerance specific to allogenic MHC complexes.

Abstract: Methods for introducing mesoporosity into zeolite materials that employ an acid pretreatment step are provided. By utilizing a non-acidic chelating agent during the acid treatment step, the zeolite material can be pretreated with a strong acid, often in higher concentrations or over shorter contact times, than had previously been contemplated. The resulting acid-treated mesoporous materials retain desirable properties, including Si/Al, UCS, and total mesopore and micropore volume. The ability to use a stronger acid without damaging the zeolite material results in a less expensive process capable of producing mesoporous zeolite materials suitable for a wide range of uses.

Abstract: In one aspect, a dual action syringe includes an external body having a distal end defining an anesthetic gel receptive concavity surrounding a needle passage through the distal end. The external body also includes a proximal end defining a plunger receptive passage. An internal body is slidably disposed in the external body. The internal body receives a needle in a distal end of the internal body and an anesthetic carpule to provide fluid flow communication between the carpule and the needle in response to pressure on the plunger. A biasing member is disposed in the external body, between the external body and the internal body, biasing a distal end of the needle away from the distal end of the external body into the external body; whereby, pressure on the plunger first moves the needle through the needle passage and subsequently provides fluid flow communication between the carpule and the needle.
