Abstract: This invention provides an oblique submerged reverse deep rotary tilling device, which includes a stander, a mounted frame, a gearbox and an oblique blade roller. However, the oblique blade roller is mainly made up of configured rotary blades whose tips bend to the same direction. The angle between the rotary tilling blade roller and the traction speed is 55˜70° while the rotary blade tips are all toward the right side of the traction speed. Side force balance blades are installed to the left side of the oblique blade roller and used to balance the axial component force of the oblique blade roller. The working pattern of this invention is an oblique submerged reverse rotary tillage method. Therefore, there is no soil restriction on the top of the tilling soil clod. Meanwhile, due to cutting soil configured regularly, the right-side soil has been cut when the rotary tilling blades soil begins tilling. The soil is mainly destroyed by tension.

Abstract: Described herein are antimicrobial peptides for use in pharmaceutical antibiotic compositions and methods of use thereof. These antimicrobial peptides are Gramicidin A (gA) peptide analogs that, in addition to having potent anti-microbial activity, have greatly increased solubility and significantly reduced toxicity in comparison to the wild-type Gramicidin A peptide.

Abstract: Provided herein is a new class of cyclic lactadherin peptides (cLac) that mimic the natural phosphatidylserine (PS)-binding activity of the parent lactadherin protein. These cLacs are useful as small molecule indicators of early stage of apoptosis and of treatment efficacy evaluation.

Abstract: Provided herein are compounds useful for selectively labeling an apoptotic cell, and methods and assays using such compounds for the detection of an apoptotic cell in vivo or in a biological sample obtained from a subject.

Abstract: Fluorescent glycosides containing aromatic hydrocarbon groups are useful in labelling and detection methods for a wide array of chemical and biological molecules. Assembly of multiple analogs to form “polyfluors” affords fluorescence properties that are different from the properties of the component analogs. This allows for the design and use of combinatorial libraries of molecules displaying widely varying fluorescence colors.

Abstract: A planar 2×2 switch is provided for controllably coupling first and second input channels to first and second output channels. The switch includes a first reflector that is movable between a first position and a second position. When the first reflector is in its second position, it reflects light from the first input channel to the second output channel and reflects light from the second input channel to the first output channel. When the first reflection is in its first position, it does not affect the optical beams in the switch. Instead, these beams are reflected by a second reflector which has two reflective surfaces. The second reflector reflects light from the first input channel to the first output channel and reflects light from the second input channel to the second output channel. Switches having a larger number of input and output channels are also provided.

Abstract: A planar 2×2 switch is provided for controllably coupling optical channels, the switch has a reflector which is movable between a first and a second position. The reflector in the first position is disposed such that it reflects the optical signal into the second output channel. The optical signal from first input channel is coupled into second output fiber. The optical signal from second input fiber is coupled into first output fiber. The reflector in the second position is disposed such that the input optical signal propagates to a second reflector and is reflected and refocused into the output fiber. The reflection direction from the second reflector introduces a double reflection by utilizing two planar reflectors. The optical signal from first input channel is reflected into first output channel. The optical signal from second input channel will be coupled into second output channel.

Abstract: A first embodiment of the present invention provides a dense wavelength division multiplexer which has a planar array of input optical channels, each channel capable of receiving an optical signal. Coupled to this planar array of input channels is a first waveguide concentrator which facilitates the reduction of the spacing between the cores of the input optical channels. A first collimating provides means for transforming the optical signals into a collimated beam. A wavelength dependent element is disposed proximate the first collimating means. A second collimating means refocuses the collimated beam into an optical channel in a second waveguide concentrator, which facilitates the expansion of the spacing between the cores of the output channels, and ultimately to an array of output optical channels.
