Therapeutic stem cells and methods for their use and manufacture. Stem cells are produced under conditions in which the stem cells are exposed to at least one environmental factor, including decreased oxygen tension. The environmental factors and culture conditions of the invention produce stem cells having an enhanced therapeutic ability and enhanced proliferation in culture. Stem cells of the invention retain their plasticity through a higher number of cell passages relative to know methods of stem cell culture.

The invention is a method for using an avian embryo to identify the neuripotency of a cell population. The invention may be used for applications such as screening for candidate neuripotent cell lines for masterbanking, validation of working cell banks, and identifying agents and conditions capable of inducing neural differentiation in a cell population.

A method to fabricate an image sensor includes providing a semiconductor substrate having a pixel region and a periphery region, forming a light sensing element on the pixel region, and forming at least one transistor in the pixel region and at least one transistor in the periphery region. The step of forming the at least one transistor in the pixel region and periphery region includes forming a gate electrode in the pixel region and periphery region, depositing a dielectric layer over the pixel region and periphery region, partially etching the dielectric layer to form sidewall spacers on the gate electrode and leaving a portion of the dielectric layer overlying the pixel region, and forming source/drain (S/D) regions by ion implantation.

A mounting apparatus includes an enclosure, a bracket for fixing a data storage device, and a resisting member. The bracket includes a base and a handle pivotably mounted to the base. The handle includes a pressing portion. The resisting member is pivotably mounted to the bracket. When the handle is rotated toward the base, the pressing portion of the handle presses a first portion of the resisting member to pivot the resisting member. A second portion of the resisting member extends through the bracket to resist against the enclosure.

An electrical connector system includes a substrate (1) connected to PHY side and an electrical connector (3) mounted on the substrate (1), a transformer (5) and a common mode filter (7). The electrical connector (3) is used to mate with a cable assembly and so forms a Cable side. The transformer (5) further includes a first wire (51) having two opposite ends electrically connected to the PHY side and a second wire (53) having two opposite ends. The common mode filter (7) has a third wire (73) and a fourth wire (75) physically separated from the second wire (53). The third wire (73) has an end electrically connected to one end of the second wire (53) and an opposite end electrically connected to the Cable side. The fourth wire (75) has an end electrically connected to the opposite end of the second wire (53) and an opposite end electrically connected to the Cable side.

A white light-emitting apparatus including a light-emitting device, a nitride fluorescent material and an oxynitride fluorescent material is provided. The light-emitting device is capable of generating a first color light having a first wavelength range. The nitride fluorescent material and the oxynitride fluorescent material cover the light-emitting device. The nitride and oxynitride fluorescent material are excited by the first color light, and further generate a second color light having a second wavelength range and a third color light having a third wavelength range, respectively. The first, second and third color lights are mixed together to generate a white light. A white light-emitting diode is also disclosed.

A mounting apparatus includes a bracket for fixing a data storage device, a handle pivotably mounted to the bracket, and a resisting member movably attached to an outer surface of the bracket. The handle includes a pressing portion. The resisting member includes a resisting portion and a connecting portion formed from one end of the resisting portion. When the handle is operated to pivot toward the bracket, the pressing portion resists against the connecting portion to bias the resisting portion to be deformed away from the outer surface of the bracket.

A mounting apparatus for mounting a number of data storage devices includes a supporting member, a connecting plate, and a number of partitioning members perpendicularly connected between the supporting member and the connecting plate. Each data storage device is sandwiched between two neighboring partitioning members. The supporting member defines a number of first latching holes. The connecting plate defines a number of second latching holes. Each partitioning member includes a partitioning plate, a first hook extending from a first end of the partitioning member, and a second hook extending out from a second end of the partitioning member. The first hook is detachably latched in the corresponding first latching hole. The second hook is detachably latched in the corresponding second latching hole.
