Abstract: A medium access control (MAC) technique of a multihop sensor network. In the multihop sensor network, the MAC technique may contribute to significantly reducing transmission delay, and allow real-time services to be provided to all nodes by extending a guaranteed time slot (GTS) restricted to one hop in a personal area network (PAN) coordinator (PNC) to all nodes. Furthermore, the MAC technique may allow the number of available GTSs to be significantly increased, by using all 16 frequency band channels instead of using only a single frequency band and setting a multi-superframe.

Abstract: A method for 3D magnetic resonance imaging (MRI) with slice-direction distortion correction is provided. One or more selective cross-sections with a thickness along a first axis is excited using a RF pulse with a bandwidth, wherein a selective cross-section is either a selective slice or selective slab. A refocusing pulse is applied to form a spin echo. One or more 2D encoded image signals are acquired with readout along a second axis and phase encoding along a third axis. Slice-direction distortion is corrected by resolving the position by resolving the frequency offset.

Abstract: A self-stabilized, levitating MEMS (Micro Electro-Mechanical Systems) resonator is provided for detection of magnetic resonance spectra of electrons and nuclei in magnetic resonance force microscopy (MRFM) measurements. The present MRFM system includes a levitating micro-disk having electrically-controlled force sensitivity. To achieve imaging on the scale of a single nuclear spin, the force sensitivity of the measurement must be on the order of 1 aN (atto-Newton) or less. For about a 1 aN force to produce deflections comparable to an angstrom for interferometer detection, the stiffness or spring constant (k) of the resonator will typically be less than 1 ?N/m (micro-Newtons per meter). Since the resonator is to be driven with an oscillating force at its resonance, there is a quality-factor (Q) enhancement of the amplitude of the motion. As a result, the k/Q ratio is preferably less than 1×10?8 N/m and is achievable with the contemplated levitating micro-disk resonator.
Abstract: The present invention is directed to methods of extracting a hydrocarbon-based product from subsurface (oil) shale formations, wherein such methods rely on the use of an extraction fluid comprising pentane for facilitating the production of a mobile hydrocarbon-based product when the pentane contacts hydrocarbons in subsurface shale. The contacting process, and the subsequent process of recovering the mobile hydrocarbon-based product, is further enhanced by the methods of fracturing and/or rubblizing portions of the shale formation, so as to enhance their fluid permeability.

Abstract: Computer implemented machine learning methods are described. A co-operative learning method involves a first rule based system and a second rule based system. A rule base is generated from input data and recursion data is used to recursively update the rule base as a result of newly received input data. Rule data defining at least one rule and associated data are sent to the second system which determines whether to update its rule base using the transmitted rule data, and if so the recursion data is used to recursively determine the updated rules for its rule base. A father machine learning method for a rule based system, involves receiving time series data, determining whether the data increases or decreases the spatial density for previously existing rules, and if so then creating a new cluster and associated rule, otherwise a new cluster is not created.
