Abstract: The present invention belongs to the technical field of processing and analysis of biomedical signals, and provides a calibration method for the critical point of mental fatigue based on self-organized criticality. It constructs a self-organized criticality model by using the dynamic characteristics of a brain network, and deduces the avalanche dynamics of mental fatigue, which is consistent with the internal mechanism of evolution of fatigue complexity. The critical state of calibration is dynamically stable and robust. Through the verification of the behavior data, the reliability of the critical state of mental fatigue determined from physiological and behavioral dimensions is high, providing support for the setting of the fatigue category labels to complete more accurate classification and recognition.

Abstract: This invention relates to adaptive resistance inhibiting 100 to 10,000 Gy, single fraction proton and carbon ion microbeam and nanobeam radiosurgery, proton spray chemotherapy and proton spray gadolinium and boron neutron capture therapy with least normal tissue toxicity. Secondary neutrons, protons, ions and radiation from the accelerator and the patient specific collimator are removed with tissue equivalent collimator that also generates proton and carbon ion microbeam and nanobeam. Laser interaction with micrometer and nanometer thick metallic and diamond like carbon targets are also used for proton and carbon ion beam generation. Polyenergetic proton beam is spatially separated. Ion beam and Laser ion beam is accelerated in a hybrid RF accelerator. It is split into microbeam and nanobeam. Secondary neutrons, protons and gamma radiation are removed with tissue equivalent collimators that also generate microbeams and nanobeams.

Abstract: One aspect of the present disclosure relates a system that can employ micromagnetic stimulation to activate or suppress one or more areas of the central nervous system. A portion of the central nervous system can be exposed. A probe can be configured to be located in proximity to the exposed portion of the nervous system. A microcoil (of a size less than or equal to 10 millimeters) can be coupled to the probe and configured to activate or suppress the portion of the central nervous system via electromagnetic induction.

Abstract: An apparatus includes a substrate and a plurality of biological material stimulators positioned on the substrate. Each biological material stimulator forms a fluctuating magnetic field capable of inducing a current in biological material.

Abstract: The described invention provides methods for irradiating skin cancer cells, such as melanoma cells, at a high radiation rate (e.g., of 2,400 mu/min) and a modest total dose (e.g., of 0.5 Gy) to treat skin cancer or induce apoptosis in skin cancer cells. The radiation may be administered in a plurality of treatments and used in conjunction with chemotherapy.

Abstract: A device and method for improving fertility among couples after intercourse is disclosed. The device and method uses an intravaginal device that collects ejaculate from the vaginal canal after intercourse and presents it to the os of the cervix. The device also serves to contain ejaculate near the cervical os to increase the chances of successful fertilization.

Abstract: An isolation and treatment enclosure system for a patient includes a bed module that supports the patient, a spool disposed at a first end of the bed module, and a flexible, continuous enclosure disposed on the spool. The flexible, continuous enclosure can be extended from the spool along a length of the bed module so as to create a tube in which the patient and the bed module are enclosed.

Abstract: A graft device is provided comprising a flow conduit and a surrounding covering. The graft device can connect a first body space and a second body space. In one embodiment, the flow conduit is a vein, such as a harvested saphenous vein, useful as an arterial graft, for example and without limitation, in a coronary artery bypass procedure.

Abstract: There is provided a method for controlling a flow of intestinal contents in the intestinal passageway of a patient's intestines. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the intestinal tissue wall) at least one portion of the intestinal tissue wall to influence the flow in the intestinal passageway, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the intestinal passageway. The method can be used for restricting or stopping the flow in the intestinal passageway, or for actively moving the fluid in the intestinal passageway, with a low risk of injuring the intestines.
