Abstract: In some embodiments, a method includes receiving, at a host device, a signal indicative of an authentication request for a client device to access a resource from a set of resources. A resource confidence value associated with the authentication request is calculated based at least in part on (1) a threat confidence vector associated with at least one risk mitigation score for each threat from a set of threats and (2) a set of resource vulnerability scores associated with the resource and each threat from the set of threats. The resource confidence value is compared to a resource confidence criterion associated with the resource from the set of resources. A signal indicative of a positive authentication is sent from the host device to the client device when the resource confidence value satisfies the resource confidence criterion such that the client device is granted access to the resource.

Abstract: In some embodiments, a method includes receiving, from a client compute device and at a server, a request to access a resource. The request can include an identifier associated with the client compute device. The method can further include accessing risk information associated with the client compute device from an instance of a distributed database at the server using the identifier. The risk information is provided to the distributed database by a set of compute devices. Each compute device from the set of compute devices implements a different instance of the distributed database. The risk information can be analyzed to identify an access decision and a level of access to the resource can be granted to the client compute device based on the access decision.

Abstract: In an embodiment, a hierarchical user interface replaces a native one-dimensional horizontal navigation system with a multi-dimensional hierarchical tree structure for organizing and navigating spreadsheet workbooks. The interface allows users to visualize the full structure and content of workbooks, quickly navigate to and select sheets, and organize workbooks in a more logical manner than sequential tabs allow.

Abstract: Disclosed herein are systems and methods for identifying the source of a signal via channel equalization using characteristics of the signal. A system receives a signal, then measures a frequency response of the signal by performing a spectral analysis over the entire signal. The system computes the average amplitude over a subset of time samples from the spectral analysis for each represented frequency and compares the set of averaged amplitudes to a stored set of averaged amplitudes to produce equalization coefficients. Applying the equalization coefficients to the frequency response yields an equalized frequency response, which is compared to a stored frequency response using a classifier to determine a match. Alternately, the system applies the equalization coefficients to the stored frequency response yielding an equalized stored frequency response. The method can recognize speakers, vehicles, electromagnetic signals, sonar signals, optical signals, videos, etc.

Abstract: Disclosed herein are systems, computer-implemented methods, and computer-readable storage media for tagging a known signal of interest. Initially, the system classifies the data from an input signal using a short-term classifier, wherein there are at least two classifications available, a first classification of the data as having no identified outputs and a second classification of the data as at least one potential signal of interest, wherein the short-term classifier also bypasses data that is known to be of no interest. After the short-term classifier classifies the inputs, it collapses the input data that is classified as having no identified outputs. This allows the short-term classifier to create time-variant data. Finally, the system will tag a known signal of interest in the time-variant data that was classified as having at least one potential signal of interest. Therefore, a system for tagging a known signal of interest is described.

Abstract: This invention describes a process for producing a nanoscale zero-valent metal, including reduction of a metal ion solution with a dithionite compound, wherein the reduction is carried out under alkaline conditions under substantially an inert atmosphere. A nanoscale zero-valent metal obtainable by this process, and having a new crystalline form, is also described. The nanoscale zero-valent metal produced by the process of the invention is preferably iron, and is advantageously used for the remediation of contaminated water.

Abstract: A computer screen dusting cloth affixable to a computer monitor case having a reel capable of winding a tether thereon. The tether is attached at a distal end to a monitor wiping cloth. The reel has a wound position with the tether wound upon it and an extended position when it is unwound from the tether. The reel is continuously biased toward the wound position but is locked to the extended position once the user pulls the attached cloth and extends the tether. This allows uninhibited use of the cloth on the monitor. A lock release in the form of a button communicating through the reel housing allows the user to wind up the tether automatically after use by a simple press of the button and storing the cloth attached to the monitor by the tether and real holding tether.

Abstract: 4,1',6'-trichloro-4,1',6'-trideoxygalactosucrose is prepared by a process including the steps of:(a) isomerizing 2,3,4,3',4'-penta-O-acetyl sucrose to 2,3,6,3',4'-penta-O-acetyl sucrose;(b) chlorinating the isomerized acetate at the 4,1' and 6'-positions; and(c) deacetylating the resulting chlorinated product; the isomerization step (a) being effected by treating a solution of 2,3,4,3',4'-penta-O-acetyl sucrose in an inert solvent with a weak acid at an elevated temperature.

Abstract: Crystalline 4,1',6'-trichloro-4,1',6'-trideoxy-galactosucrose exists as the orthorhombic anhydrous form and as the pentahydrate, both of which are more stable than amorphous TGS. Crystals are obtained from seeded aqueous solutions, above 38.degree. C. for the anhydrate; below 38.degree. C. for the pentahydrate.
