In mathematics, a matrix is a rectangular array of numbers, symbols, or expressions. The individual items in a matrix are called its elements or entries. An example of a matrix with six elements is Matrices of the same size can be added or subtracted element by element. The rule for matrix multiplication is more complicated, and two matrices can be multiplied only when the number of columns in the first equals the number of rows in the second. Wikipedia.

A clamp for a flexible pipe, to provide a load bearing flange on the flexible pipe permitting buoyancy jackets to be joined thereto. The clamp has a longitudinal axis arranged to extend along the length of the flexible pipe and a radial axis being perpendicular to the longitudinal axis. The clamp further comprises: a plurality of separate clamp elements being supported together in a radial array extending at least partially around the longitudinal axis; engagement means located between neighbouring clamp elements to movably interconnect the clamp elements; and a strap being adapted to surround the clamp elements, in use for exerting a compressive force thereon. Also provided is a clamp element for use in the aforementioned clamp.

This disclosure describes techniques for creating stable, targeted mutations in Spirulina (Athrospiria) and Spirulina having stable, targeted mutations.


A wired information and physical system includes a wired system for electric power and data communication, and a background server that is connected to the wired system and performs data storage, processing and analysis. The wired system includes a module-bearing platform and a plurality of function modules removably attached to the platform. The platform and the plurality of the function modules encloses a wire pathway that is further divided into a strong current wire tunnel, a weak current wire tunnel, and a wire duct. A strong current conductive wire is located within the strong current wire tunnel and can provide electric power. A weak current conductive wire and a network cable are located within the weak current wire tunnel, and connect the modules and the server for data and instructions transmission. The system allows reliable control of intelligent terminals and enhances home safety and stability.


A wiring system comprising a module-bearing platform and a plurality of function modules is disclosed. The system comprises a strong current wire tunnel, a weak current wire tunnel, and a wire duct. The strong current wire tunnel contains a strong current conductive wire linking power mains; the weak current wire tunnel contains a weak current conductive wire and a network cable connected to a background server. A method is also disclosed that integrates accessing mains power, providing weak current electric power source, and conducting data communication within a single wired system. The system and the method eliminate signal instability present in wireless communications of smart home settings and provide enhanced safety, compatibility and a flexible wire structure for easy and unrestricted accommodation of function modules according to the needs of users.


This disclosure describes modified photosynthetic microorganisms, including Cyanobacteria, that have a reduced amount of a light harvesting protein (LHP) polypeptide and contain one or more introduced or overexpressed polynucleotides encoding one or more enzymes associated with lipid biosynthesis, and which are capable of producing increased amounts of fatty acids and/or synthesizing triglycerides.


The present invention relates to a novel bioactivity testing structure for single cell tracking using a gelling agent and a bioactivity testing system including the testing structure. The present invention also relates to bioactivity testing, drug susceptibility testing, antibiotic screening, and diagnostic methods using the testing structure. The bioactivity testing structure of the present invention enables very rapid and simple drug susceptibility testing of bacteria, particularly Mycobacterium tuberculosis, drug screening, and bacterial diagnosis. Particularly, the use of the testing structure enables DST and diagnosis of bacteria only by pretreatment without the need to concentrate human sputum samples irrespective of inoculum effect, ensuring rapid, accurate, and simple testing compared to conventional tuberculosis diagnosis or DST systems. In addition, the testing structure of the present invention simultaneously enables the diagnosis and drug susceptibility testing of tuberculosis. Therefore, the present invention provides an effective alternative to the prior art.


Residue depth accurately measures burial and parameterizes local protein environment. Depth is the distance of any atom/residue to the closest bulk water. We consider the non-bulk waters to occupy cavities, whose volumes are determined using a Voronoi procedure. Our estimation of cavity sizes is statistically superior to estimates made by CASTp and VOIDOO, and on par with McVol over a data set of 40 cavities. Our calculated cavity volumes correlated best with the experimentally determined destabilization of 34 mutants from five proteins. Some of the cavities identified are capable of binding small molecule ligands. In this study, we have enhanced our depth-based predictions of binding sites by including evolutionary information. We have demonstrated that on a database (LigASite) of ∼200 proteins, we perform on par with ConCavity and better than MetaPocket 2.0. Our predictions, while less sensitive, are more specific and precise. Finally, we use depth (and other features) to predict pKas of GLU, ASP, LYS and HIS residues. Our results produce an average error of just <1 pH unit over 60 predictions. Our simple empirical method is statistically on par with two and superior to three other methods while inferior to only one. The DEPTH server (http://mspc.bii.a-star.edu.sg/depth/) is an ideal tool for rapid yet accurate structural analyses of protein structures.
