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.

Natalizumab is a safe and efficacious treatment for inflammatory and autoimmune diseases, such as multiple sclerosis, Crohn's Disease, and rheumatoid arthritis. Chain swapping between natalizumab and IgG4 molecules acts to reduce the level of bivalent natalizumab present following administration of natalizumab, and thus to lower the activity of natalizumab in the patient. Differences in IgG4 levels across patients or within a single patient across time may change the pharmacokinetic profile of natalizumab. Patients with lower levels of IgG4 may experience higher nadir levels of natalizumab during a dosing period. Monitoring IgG4 and / or bivalent natalizumab levels, and determining a dose or dosage period based on the monitoring may improve the safety and / or efficacy of natalizumab 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.
