Optical MEMS chemical sensor array
A change in mass of a microbridge in a mass sensor can be sensed by applying a time-varying amplitude modulated electrostatic force to excite the microbridge into resonance at the frequency of amplitude modulation.

Mapping a two-dimensional image to a cylindrical surface using a tuned distortion curve
In a typical two-dimensional rectilinear image, all pixel widths are constant across the image. If the two-dimensional rectilinear image is mapped to a cylindrical surface, the pixels at the edge of the image are viewed at an angle, making the effective width of the pixels at the edge smaller than the effective width of the pixels in the interior of the image.

High-voltage MOSFETs having current diversion region in substrate near fieldplate
To limit or prevent current crowding, various HV-MOSFET embodiments include a current diversion region disposed near a drain region of an HV-MOSFET and near an upper surface of the semiconductor substrate. In some embodiments, the current diversion region is disposed near a field plate of the HV-MOSFET, wherein the field plate can also help to reduce or “smooth” electric fields near the drain to help limit current crowding. In some embodiments, the current diversion region is a p-doped, n-doped, or intrinsic region that is at a floating voltage potential. This current diversion region can push current deeper into the substrate of the HV-MOSFET (relative to conventional HV-MOSFETs), thereby reducing current crowding during ESD events. By reducing current crowding, the current diversion region makes the HV-MOSFETs disclosed herein more impervious to ESD events and, therefore, more reliable in real-world applications. |

Peptides specific for hepatocellular carcinoma cells and applications thereof
Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer death worldwide. Novel treatment strategies derived from increased knowledge of molecular oncology are constantly being developed to cure this disease. Here, we used phage display to identify novel peptides, including (SP94), which binds specifically to HCC cells. In vitro, the phage clone PC94 binds to HCC cell lines. In vivo, PC94 homed specifically to tumor tissues but not to normal visceral organs in SCID mice bearing human HCC xenografts. The homing ability could be competitively inhibited by synthetic peptide, SP94. PC94 localized to tumor tissues but could not be detected in SP94-competed tumor tissues or in normal organs. In addition, PC94 recognized the tumor tissue but not non-tumor tissue in surgical specimens from HCC patients, with a positive rate of 61.3% (19/31). With the conjugation of SP94 and liposomal doxorubicin, a targeted drug delivery system enhanced the therapeutic efficacy against HCC xenografts through enhanced tumor apoptosis and decreased tumor angiogenesis. Our results indicate that SP94 can improve the systemic treatment of patients with advanced HCC. |

Fragrant gel polymer with water
The fragrant gel polymer system is a process where a fragrance formulation is divided and blended with a polymer and a cross-linking agent. The polymer is then liquefied and made homogenous with a solvent, including esters. The solvent modifies viscosity and later eases the mixing of the polymer with the cross-linking agent. The cross linking agent is then liquefied and blended with water and aliphatic alcohol reducing steric hindrance. Mixing of the fragrance carrying polymer and the cross linking agent results in a gel that sets in less time and with less syneresis than existing processes. The resulting gel achieves a near transparent form and receives dyes while attaining various molded shapes. |
