The miniaturized piezoelectric accelerometer includes a support frame (102) having a cavity (104) and a seismic mass (108) supported by a plurality of suspension beams (110) extending from the support frame (102). Each of the suspension beams (110) has a piezoelectric thin film coated on a top surface thereof, with a pair of inter-digital electrodes (114) deposited on an upper surface of each piezoelectric thin film. The presence of acceleration excites bending and thus strain in the piezoelectric thin film, which in turn causes electrical signals to be generated over terminals of the electrodes (114). To collect constructively the output of the electrodes (114), one terminal of each of the electrodes (114) is routed to and electrically connected at a top surface (308) of the seismic mass (108).

According to various embodiments, there is provided a method of acquiring information from volatile memory of a mobile device, the method including: accessing the volatile memory of the mobile device used by an application operating on the mobile device to store communicated information with a communication device; acquiring a copy of data present in the volatile memory; and analyzing the copy of data to extract the communicated information.

A polymer fiber is formed by hydrodynamic spinning. Fluids are forced to flow through a conduit to form a laminar flow comprising three or more layers of generally coaxial fluid flows, at respective flow rates selected to define a cross-section of a tubular middle layer of the fluid flows. The middle layer comprises a cross-linkable polymer precursor. Another layer of the fluid flows comprise a cross-linking agent. The polymer precursor, cross-linking agent and fluids are selected to prevent substantial diffusion of the polymer precursor away from the middle layer, and to allow a portion of the cross-linking agent to diffuse from the another layer into the middle layer to facilitate cross-linking of the polymer precursor in the middle layer to form a tubular polymer layer in a polymer fiber. The polymer layer thus has a cross-section generally corresponding to the cross-section of the middle layer.

A piezoelectric actuator device includes a substrate anchor region; a support beam arrangement having first and second ends, wherein the first end is fixed to the anchor region and the second end is freely suspended; first and second beams having first and second ends, wherein the first end of each beam is mechanically fixed to at least a part of the second end of the support beam arrangement and the second end of each beam is freely suspended; a coupling beam mechanically coupling the second end of the first and second beams; wherein the first and second beams are arranged such that the first end of the support beam arrangement is located between the coupling beam and the second end of the support beam arrangement.

The disclosure relates to the expression of podocalyxin-like protein (PODXL) on the surface of induced pluripotent stem cells and particularly, although not exclusively, to the use of PODXL as a marker of induced pluripotent stem cells.

Embodiments provide a gm-ratioed amplifier. The gm-ratioed amplifier comprises a first input voltage terminal and a second input voltage terminal, a first output voltage terminal and a second output voltage terminal, and an amplifying unit. The amplifying unit may be coupled between the input voltage terminals and the output voltage terminals and may be adapted to supply an output voltage to the output terminals in dependence on an input voltage supplied to the input terminals. The amplifying unit may comprise a gm-load, which comprises a first load branch comprising a first field effect transistor, and a second load branch comprising a second field effect transistor. A first source/drain terminal and a gate terminal of the first field effect transistor may be coupled to the first output voltage terminal, and a first source/drain terminal and a gate terminal of the second field effect transistor may be coupled to the second output voltage terminal. A second source/drain terminal of the first field effect transistor and a second source/drain terminal of the second field effect transistor may be coupled with each other through a first transistor arrangement such that a linearity of response of the output voltage to the input voltage is improved.

A computer-implemented process is provided for reorienting a three-dimensional (3D) scan image of an object. The object has a generally flat surface. The image is constructed from image data obtained during rotation of the object about a rotation axis, which intersects the plane of the flat surface at an angle. Axial slices of the scan image are obtained, each of which represents a slice of the object that is perpendicular to the rotation axis and comprises a line representing the flat surface of the object. The axial slices are shifted to align lines representing the flat surface in different axial slices, thus forming a reoriented 3D image. Alternatively, an axial tilt angle is determined from the positions of these lines and the image is rotated by the determined angle to form a reoriented 3D image.

We disclose a method of preparing a conditioned cell culture medium, the method comprising the steps of: (a) culturing a mesenchymal stem cell (MSC), a descendent thereof or a cell line derived therefrom in a cell culture medium; and (b) optionally isolating the cell culture medium; in which the mesenchymal stem cell (MSC) is obtained by propagating a cell obtained by dispersing a embryonic stem (ES) cell colony, or a descendent thereof, in the absence of co-culture in a serum free medium comprising FGF2.
