A dual-energy x-ray imaging system searches a moving automobile for concealed objects. Dual energy operation is achieved by operating an x-ray source at a constant potential of 100 KV to 150 KV, and alternately switching between two beam filters. The first filter is an atomic element having a high k-edge energy, such as platinum, gold, mercury, thallium, lead, bismuth, and thorium, thereby providing a low-energy spectrum. The second filter provides a high-energy spectrum through beam hardening. The low and high energy beams passing through the automobile are received by an x-ray detector. These detected signals are processed by a digital computer to create a steel suppressed image through logarithmic subtraction. The intensity of the x-ray beam is adjusted as the reciprocal of the measured automobile speed, thereby achieving a consistent radiation level regardless of the automobile motion. Accordingly, this invention provides images of organic objects concealed within moving automobiles without the detritus effects of overlying steel and automobile movement.

Embodiments disclosed herein provide a behavioral based solution to user identity validation, useful in real-time detection of abnormal activity while a user is engaged in an online transaction with a financial institution. A risk modeling system may run two distinct environments: one to train machine learning algorithms to produce classification objects and another to score user activities in real-time using these classification objects. In both environments, activity data collected on a particular user is mapped to various behavioral models to produce atomic elements that can be scored. Classifiers may be dynamically updated in response to new behavioral activities. Example user activities may include login, transactional, and traverse. In some embodiments, depending upon configurable settings with respect to sensitivity and/or specificity, detection of an abnormal activity or activities may not trigger a flag-and-notify unless an attempt is made to move or transfer money.

This invention provides a continuous process of making continuous nanofibers of all kinds, such as SiC, BN, AlN, and C. Laser heating a vapor of feed-material made of all atomic elements needed to grow chosen nanofibers results in growth of nanofibers onto seed-nanostructures attached to a filament, which is then pulled up continuously at a rate controlled by a rate of growth of the nanofibers. More feed-material is supplied at a rate sufficient to enable the nanofibers to grow longer continuously without limit. Laser light focused into a doughnut shape provides a photon density gradient, which constrains the nanofibers to grow parallel to each other and in the form of cylinders, so that industrially useful structures like cables and cylinders can be made in one low cost operation and in large quantities.

As typically embodied, the inventive method features bombardment of atomic nuclei with ³He ions in order to effect transmutation of atoms from a first atomic element to a second atomic element. Two notable inventive genres describe transmutation of: oxygen to nitrogen in an oxygen-containing target (e.g., including ZnO film); and, carbon to boron in a carbon-containing target (e.g., including SiC film). According to the former, transmutation of ¹⁶O to ¹⁵N occurs; more specifically, transmutation of ¹⁶O to ¹⁵O occurs via nuclear bombardment, and then transmutation of ¹⁵O to ¹⁵N occurs via decay by positron emission. According to the latter, transmutation of ¹²C to ¹¹B occurs; more specifically, transmutation of ¹²C to ¹¹C occurs via nuclear bombardment, and then transmutation of ¹¹C to ¹¹B occurs via decay by positron emission. Inventive practice frequently results in significant alteration of at least one physical property among: electronic carrier concentration; resistivity; photoconductivity; luminescence; morphology.
