A method, apparatus and program storage device for magnetic disk drive protection is provided. A stable position data storage stores stable-state information representing a magnetic disk drive in an operating environment that satisfies a certain condition. An acceleration sensor senses changes in acceleration acting on the magnetic disk drive and a rest-state measuring unit determines whether the magnetic disk drive is in a state of rest based on information acquired by the acceleration sensor. An operating state determination unit, in response to a first determination by the rest-state measuring unit that the magnetic disk drive is in a state of rest, determines when the state of rest corresponds to the stable-state information stored in the stable position data storage, and sets a detection sensitivity to a sign that which indicates an impending shock to the magnetic disk drive based on a result of a second determination. A magnetic head operation controller controls operation of the magnetic disk drive including retraction of a magnetic head based on the detection sensitivity set by the operating state determination unit.

A clinically valuable method is provided for evaluating the onset or progression of Alzheimer's disease using a non-invasive biomarker obtained from an independent component analysis (ICA) of an individual's resting state functional MRI. The method is relatively more automated and objective than previous methods and exploits dysfunctional connectivity across an entire network of brain regions in Alzheimer's disease. It eliminates the need for investigator's intervention as much as possible and is more robust than structural and functional methods targeting the hippocampus.

Rotatable tool for chip removing machining includes a rotatable holder part and a cutting part that is detachably connected to a front end of the holder part. In the front end of the holder part, a forwardly open slot is formed, which separates two elastically flexible branches of the holder part. For clamping of the cutting part on the holder part, a male / female coupling is provided, which comprises a pin on either the holder part or the cutting part and a corresponding pin-receiving seat in the other part. If the pin is on the holder part, then a manually induced elastic deformation of the branches towards one another reduces the diameter of the pin to enable the pin to enter the female part. Subsequent return of the branches toward a rest state thereof causes the diameter of the pin to expand and tightly hold the cutting part. Alternatively, if the seat is disposed on the holder part, then a manually induced elastic deformation of the branches away from one another increases the diameter of the seat to enable the pin to enter the female part. Subsequent return of the branches toward the rest state causes the diameter of the seat to contract and tightly hold the cutting part.
