Fuzzy whitelisting anti-malware systems and methods
In some embodiments, an anti-malware system accounts for benign differences between non-malicious data objects, such as differences introduced by compilers and other polymorphisms. A target object is separated into a multitude of code blocks, and a hash is calculated for each code block. The obtained set of target hashes is then compared against a database of hashes corresponding to code blocks extracted from whitelisted objects. A target object may be labeled as whitelisted (trusted, non-malicious) if it has a substantial number of hashes in common with a whitelisted object. Objects which are slightly different from known whitelisted objects may still receive whitelisting status. By allowing a certain degree of mismatch between the sets of hashes of distinct objects, some embodiments of the present invention increase the efficiency of whitelisting without an unacceptable decrease in safety. |

Web content fingerprint analysis to detect web page issues
Techniques and solutions are described for detecting potential problems with web pages. For example, a web page can be analyzed (e.g., during loading of the web page) to determine statistics, such as size and structure statistics.

Problems such as web page spoofing can be detected if the same web page content (e.g., content with a high degree of statistical similarity) is obtained from two different web sites. For example, a web page that is retrieved from one web site that matches a statistical model representing the same web page from another web site can indicate a spoofed web page. |

Precoding and scheduling for a cellular communication system using a large number of base stations antennas
For an infinite number of transmit antennas at a base station (BS), matched filter (MF) precoding (a type of precoding used to perform SU-MIMO transmission) becomes optimal for performing spatial multiplexing.

Cross-section areas of different rods on a reference plane parallel to the substrate are different, and cross-section areas of the connecting portion on the reference plane decrease along the first direction. The light-emitting layer is located on sidewalls of the rods. The second-type doped semiconductor layer is located on the light-emitting layer. A manufacturing method of the semiconductor light-emitting device is also provided. |

Workpiece cutting method
The object cutting method comprises a step of locating a converging point of laser light within a monocrystal sapphire substrate, while using a rear face of the monocrystal sapphire substrate as an entrance surface of the laser light, and relatively moving the converging point along each of a plurality of lines to cut set parallel to the m-plane and rear face of the substrate, so as to form first and second modified regions within the substrate along each line and cause a fracture to reach a front face. In this step, in each line, with respect to a tilted surface passing the first region while being parallel to the r-plane of the substrate, the second region is positioned on the side where the tilted surface and rear face form an acute angle. |

Interface between a I/III/VI2 layer and a back contact layer in a photovoltaic cell
The invention relates to a method of manufacturing a I-III-VI2 layer with photovoltaic properties, comprising: deposition of a metal on a substrate to form a contact layer, deposition of a precursor of the photovoltaic layer, on the contact layer, and heat treatment of the precursor with an addition of element VI to form the I-III-VI2 layer. The element VI usually diffuses into the contact layer (MO) during the heat treatment and combines with the metal to form a superficial layer (SUP) on the contact layer.In the method of the invention, the metal deposition comprises a step during which an additional element is added to the metal to form a compound (MO-EA), in the contact layer, acting as a barrier to the diffusion of the element VI, which allows precisely controlling the properties of the superficial layer, particularly its thickness. |
