A non-invasive, early stage method to obtain quantitative measures of mild cognitive impairment useful in diagnosing and following degenerative brain disease or closed head injuries by utilizing the image data from individual patient positron emission tomographic scans to construct a cognitive decline index that serves as a diagnostic and screening tool to reveal the onset of mild cognitive impairment and nervous system dysfunction which are sequelae of degenerative brain diseases and closed head injury. The method involves using weighted values of brain region intensities derived from comparing scans of normal subjects to a scan of the patient to calculate a cognitive decline index that is useful as a diagnostic tool for mild cognitive impairment. The weights for the intensity values for each region are derived from the differences of intensity values from regions of the brain of the patient selected by comparing the patient to normal control subjects.

A method of developing a gene expression profile indicative of the presence or stage of a selected a disease, disorder or genetic pathology in a mammalian subject employs penalized discriminant analysis with recursive feature elimination. A method of diagnosing a cancer in a mammalian subject includes the steps of examining a sample containing the subject's immune cells and detecting a variance in the expression of a statistically significant number of genes, e.g., at least 10 non-tumor genes from those same genes in a characteristic disease or healthy gene expression profile. A significant variance in expression of these genes when compared to a gene expression profile, preferably an average gene expression profile of a normal control, or significant similarities to an average gene profile of subjects with cancer, correlates with a specific type of cancer and / or location of tumor.

Anomalous control and data flow paths in a program are determined by machine learning the program's normal control flow paths and data flow paths. A subset of those paths also may be determined to involve sensitive data and / or computation. Learning involves collecting events as the program executes, and associating those event with metadata related to the flows. This information is used to train the system about normal paths versus anomalous paths, and sensitive paths versus non-sensitive paths. Training leads to development of a baseline “provenance” graph, which is evaluated to determine “sensitive” control or data flows in the “normal” operation. This process is enhanced by analyzing log data collected during runtime execution of the program against a policy to assign confidence values to the control and data flows. Using these confidence values, anomalous edges and / or paths with respect to the policy are identified to generate a “program execution” provenance graph associated with the policy.

Provided is a brake control apparatus for a vehicle which detects an amount of brake-pedal operation by means of an electric signal, and then calculates a braking force demanded by a driver from the electric signal, and thereby generates the demanded braking force. A control mode for a braking force is switched from a normal control mode to a stationary-vehicle control mode, if a determination that the vehicle is in a stationary state is followed by another determination that an electric signal corresponding to an actual braking force exceeds a command value for a stationary-vehicle braking force while the vehicle is in the stationary state. The control mode for a braking force is switched from the stationary-vehicle control mode to the normal control mode, if it is determined that the demanded braking force becomes smaller than the command value for the stationary-vehicle braking force. In addition, in the stationary-vehicle control mode, a braking force generated by a means for braking is equal to the command value for the stationary-vehicle braking force, whereas, in the normal control mode, the braking force generated by the means for braking is equal to the braking force demanded by the driver.

When downshift control is performed during fuel cut control (when coast-down gearshift control is performed), fuel cut reset revolutions are lowered and set to revolutions Ndwn that are lower than fuel cut reset revolutions Nnor for normal control. By such a setting, it becomes possible to maintain fuel cut control and deceleration lockup slippage control even when engine revolutions NE temporarily drop during execution of coast-down gearshift control, so an improvement in fuel consumption can be achieved. Moreover, it becomes unnecessary to set a downshift gearshift line to a higher vehicle speed side, so fuel cut can be maintained while suppressing the occurrence of a gearshift shock.

An automated shifting system for a manual transmission having a neutral clutch connecting an engine to a multiple ratio transmission, the transmission having servo operated gear shift mechanism. A driver-controlled gear shift switching mechanism is used to activate the servos that effect ratio range changes. A gear shift switching mechanism includes multiple switches for triggering operation of the servos that control the ratio range changes. A range sensing redundancy strategy for the ratio range switches provide improved protection against an unintended change in direction due to three-bit separation between bits of the valid codes and to a range sensing switch failure strategy by identifying when a range change commanded by the driver exhibits a single-point fault condition. A fault condition due to a single-point sensing switch failure is identified even in those instances when a range change commanded by the driver allows continued normal control system operation, although the driver is notified of the failure by a system warning device.

A cooling system has a configuration in which a cooling system for an inverter device and a motor generator also serves as a cooling system for a battery. In this configuration, a control device performs temperature-raising control of the battery when a battery temperature is below a prescribed temperature lower limit value. The control device controls an operation of a switching valve such that cooling water from a cooling medium path is outputted to a bypass path. Further, if a cooling water temperature is lower than a prescribed temperature, the control device controls the inverter device such that a power loss during a switching operation in a switching element included in the inverter device becomes larger than a power loss during normal control. As a result, the cooling system having a small-sized, low-cost configuration rapidly recovers capacity decline of the battery, which occurs at low temperatures.

A voltage regulator (10) having an undervoltage protection circuit 11 and a method for protecting against an output voltage out being less than a predetermined level. The voltage regulator has an undershoot limitation circuit (11) coupled between a feedback network (30) and a regulation section (42). A power factor correction circuit (46) is connected to the regulation section. An output voltage out from the power factor correction circuit (46) is fed back to the feedback network (30), which transmits a portion of the output voltage to the undershoot limitation circuit (11). If the output voltage is greater than the predetermined voltage level, a switching circuit portion (34) of the undershoot limitation circuit (11) transmits a normal control signal to the regulation circuit (42). If the output voltage is less than the predetermined voltage level, the switching circuit portion transmits an enhanced control signal to the regulation circuit. The enhanced control signal quickly brings the output voltage up to at least the minimum desired level.

An AC-DC converter converts an alternating-current voltage, supplied from an external power supply, to a direct-current voltage higher than a peak voltage of the alternating-current voltage, and outputs the direct-current voltage to a first power supply line. In a normal control mode, a DC-DC converter steps down a voltage of the power supply line through on / off control over a switching element to charge a main battery. On the other hand, in an upper arm ON control mode, the DC-DC converter charge the main battery while the switching element is kept in an on state. On the basis of a state of external charging, a control device applies the upper arm ON control mode when a condition that upper arm ON control is applicable is satisfied, and applies the normal control mode when the condition is not satisfied.
