This invention relates to a method and system for providing digital security by means of a reconfigurable physical uncloneable function, RPUF. The RPUF comprises a physical system constituted by distributed components arranged to generate a first response when receiving a first challenge at a point of the physical system. The physical reconfiguring of the RPUF comprises redistributing the components such that they generate a second response, which differs from said first response, when again applying the first challenge at the point. The reconfiguration step is further utilized in providing secure storage for digital items. The digital item is data of any kind, including data that needs to be accessed and updated, i.e. which is dynamic in nature. The method is exemplified by implementations such as secure storage of a key, a secure counter and a seed generator.

A system and a method of performing a frameless image-guided biopsy uses imaging, a six-dimensional robotic couch system, a laser guidance system, an optical distance indicator, and a needle control apparatus. A planning CT scan is made of the patient with stereotactic fiduciary markers to localize and produce digitally reconstructed radiographs. Two stereoscopic images are generated using an imaging device to visualize and identify a target tumor. The images are fused with the digitally reconstructed radiographs of the planning CT scan to process tumor location. The tumor location data are communicated to the movable robotic couch to position the target tumor of the patient at a known isocenter location. A biopsy needle is guided with a laser alignment mechanism towards the isocenter at the determined depth using a needle positioning apparatus and an Optical Distance Indicator, and a biopsy sample of the target tumor is obtained.

The invention relates to a preparation method for a zinc-iron-selenium-rich biological fertilizer and a usage, which belongs to the technical field of crop production. Water is added into pig manure, silkworm excrement, human excrement and colza cakes for a fermentation to get mother liquor of the biological fertilizer; zinc sulfate, green copperas, sodium selenite are added into the mother liquor for reactions to get zinc-iron-selenium-rich biological foliar fertilizer for the rice. The fertilizer is separately sprayed in the booting stage and the full heading stage of the rice, with an amount of 1000ml per mu. The function rice, with zinc content 19.4 to 28.7mg/kg, iron content 7.0 to 20.2mg/kg, and selenium content 0.08 to 0.15 mg/kg, measures up to the limit standards of zinc, iron, and selenium in the national food standards. Organic selenium accounts for more than 99% of the total selenium in the zinc-iron-selenium-rich function nutritive rice. The preparation method for the zinc-iron-selenium-rich biological fertilizer proves effective, economical, safe and non-polluted through twice foliage sprays with zinc-iron-selenium fertilizer for the rice as an experiment.

Alpha 4 inhibitors are used in treatment of inflammatory and autoimmune diseases, such as multiple sclerosis, Crohn's Disease, rheumatoid arthritis and asthma. Rare occurrences of progressive multifocal leucoencephalopathy during treatment with an alpha-4 agent suggest the possibility that it may be related to such treatment. Monitoring for the JC virus and educating caregivers and patients about the manifestations of progressive multifocal leucoencephalopathy can improve the safety of alpha 4 inhibitor therapy.

Disclosed is a kitchen exhaust hood and makeup unit control system comprising a control device for controlling the variable speed drive (VSD) for the associated fan, and measurement devices comprising Volatile Organic Compound (VOC) gas transmitter devices and temperature transmitters devices. The exhaust fan VSD speed is controlled to maintain the kitchen hood area at certain comfort level (indoor air quality and thermal comfort) by monitoring the VOC concentration and exhaust duct temperature. The air quality sensors measure the concentration of multiple gases and odorous substances in the air with constant output. These substances, for example, may be cooking smoke, kitchen vapors, human odors and unpleasant smells. The exhaust fan speed is controlled using the proportional-integral-derivative (PID) control loop. The kitchen exhaust and make-up unit supply airflow rate may be measured by an airflow measurement means such as Fan Airflow Station. The kitchen make-up unit fan speed is controlled to maintain the constant airflow difference between the exhaust air and make-up air to maintain the slightly negative pressure in the kitchen area.
