Ben - Gurion University of the Negev | Date: 2017-04-05

The present invention discloses stable composite membranes comprising a porous support having one or more thin selective layers coated on a top surface thereof, whereas at least one of said thin selective layers comprises a crosslinked fluorinated silicone polymer, and further wherein the total thickness of said one or more thin selective layers ranges between 0.1 to 10 microns. The use of these membranes in the process of olive oil wastewater treatment and the valorization of polyphenol-rich by-products, are also disclosed.


The invention relates to a system for protecting a computerized device from a malicious activity resulting from a malicious code, which comprises^ (a) a first DC supply monitoring unit which is located within a separate computerized environment, namely an environment which is totally separated and isolated both physically and in terms of connectivity from the hardware and software of the computerized environment of the device! (b) a memory database for storing one or more signatures of known malicious events, each of said signatures describes the temporal effect of a malicious event, respectively, on the power consumption from the DC supply of the device! and (c) a microprocessor within said DC supply monitoring unit for continuously monitoring the power consumption from said DC supply of the device, comparing temporal characteristics of the power consumption with said malicious events signatures in said database, and alerting upon detection of a match, wherein said DC supply monitoring unit is at most physically connected to the DC supply of the device.

The present invention relates to a method and a framework that automatically and dynamically derives a misuseability score for every IT component (e.g., PC, laptop, server, router, smartphone, and user or any other element that can be connected to organization network or to the internet). The dynamic framework of the present invention supports the risk analysis process. The misuseability score encapsulates the potential damage that can be caused to the organization in case that an asset is compromised and misused, for example, as part of a cyber-attack.

Abstract Abstract Abstract The invention is a device for up-conversion of Short Wavelength Infra-Red (SWIR) images into visible images. The device comprises a sub micrometer thickness structure that is composed of several sub-layers, each having a typical thickness of tens to hundreds of nanometers. The device is composed of two main sections one on top of the other: (a) a highly efficient SWIR absorption thin layer and (b) a highly efficient organic light emitted diode (OLED). The generated visible image is emitted from the OLED through a top transparent cathode, which is deposited on the OLED.

A gain cell includes a write bit line input, a read bit line output, a write trigger input and a read trigger input. The gain cell also includes a write transistor, retention element and read transistor. Each of the transistors includes a respective first diffusion connection, gate connection and second diffusion connection. The write transistor first diffusion connection is connected to the write bit line input and the write transistor gate connection is connected to the write trigger input. The read transistor first diffusion connection being connected to the read bit line output and the second diffusion connection is connected to the read trigger input. The retention element buffers between write transistor and the read transistor during data retention. The retention element also connects or disconnects a write transistor diffusion connection to/from a constant voltage in accordance with a retained data level at the read transistor gate connection.


The invention relates to a system for protecting a computerized device from activities within the device bootstrap, which comprises: (a) a DC supply monitoring unit for monitoring power consumption of the DC supply of the device during bootstrap; and (b) a database for storing one or more valid bootstrap signatures, each of said valid bootstrap signatures describes a valid variation of power consumption pattern, respectively, from the DC supply of the device; wherein, during bootstrapping of the device, said DC supply monitoring unit continuously monitors the power consumption from said DC supply of the device, compares characteristics of the power consumption with said one or more valid bootstrap signatures in said database, and alerts upon detection of a mismatch.


A method of preventing or treating xenotransplant rejection in a subject in need thereof is disclosed. The method comprises administering a therapeutically effective amount of alpha-1-antitrypsin (AAT) in combination with a therapeutically effective amount of an anti-CD8 antibody or an antigen binding fragment thereof.


Patent

A method for performing optical constellation conversion, according to which each received symbol from a constellation of input symbols is optically split into M components and each component is multiplied by a first predetermined different complex weighing factor, to achieve M firstly weighted components with different amplitudes. Then a nonlinear processor optically performs a nonlinear transform on each M firstly weighted components, so as to obtain M outputs which are linearly independent, Finally, a linear processor optically performs a linear transform to obtain a new converted constellation by optically multiplying, in the complex plane, each of the M outputs by a second predetermined different complex weighing factor, to achieve M secondly weighted components and then summing the M secondly weighted components.
