Abstract: A database manager maintains a database including information tracking a set of storage units and a set of storage appliances on which the storage units currently reside. At least a portion of the tracking information is cached in a server cache at a namespace redirection server. Some of the tracking information is cached in a set of client caches at a set of clients. A request to access a storage unit is received at a client. A lookup is made into a client cache at the client to find a storage appliance having the storage unit. A determination is made that there is a problem accessing the storage unit using the client cache. So, the namespace redirection server is queried for updated tracking information concerning a location of the storage unit. The client assists the namespace redirection server with management of the server cache.

Abstract: A neural network is trained and implemented to simultaneously remove noise and artifacts from medical images using a Generalized noise and Artifact Reduction Network (“GARNET”) method for training a convolutional neural network (“CNN”) or other suitable neural network or machine learning algorithm. Noise and artifact realizations from phantom images are used to synthetically corrupt images for training. Corrupted and uncorrupted image pairs are used for training GARNET. Following the training phase, GARNET can be used to improve image quality of routine medical images by way of noise and artifact reduction.

Abstract: In at least one embodiment, a process of forming a polymer includes supplying a feed having one or more olefin monomers and a solvent; contacting the feed with a catalyst to form a reaction mixture; treating the reaction mixture in a first separator to form a first polymer-rich mixture; introducing the first polymer-rich mixture into a second separator; introducing a volatile component and/or inert component into the first separator, the second separator and/or a line between the first separator and the second separator; treating the first polymer-rich mixture to form a second polymer-rich mixture; and devolatilizing the second polymer-rich mixture to obtain the polymer.

Abstract: Embodiments for a system and method for secure authentication of backup clients in a way that eliminates the need to create users for backup client authentication anywhere in the backup ecosystem, and which eliminates the need for credentials, such as passwords that need protection, updating and synchronization. Such embodiments use a short-term token, such as a JSON web token, for both client and server authentication within the system, and verifies that the tokens grant access using the public key corresponding to the private key assigned to the directory objects by the creator of the directory objects.

Abstract: Embodiments for validating a dynamically downloaded client-side library using a kernel that downloads the library and computing a hash value of the library using a nonce value received from a server and the library code. The kernel sends the hash value to the server with a file identifier. The server finds the identified library and compares the received hash value to its own computed value calculated over the file and using the same nonce value. If the client sends the correct value, then the server allows the application to connect to the server and use the server's services. If the client sends a value other than the value calculated by the server, the server closes the connection from the client and denies access to the application.

Abstract: An axial piercing mechanism for a pressurized gas canister includes a housing, electric motor assembly, pushrod assembly, and lancet. The housing defines one or more radial exhaust ports and coaxial internal cavities. The electric motor assembly and pushrod assembly are disposed in the respective first and second cavities. The pushrod assembly is coupled to the electric motor assembly and is rotatably driven along the longitudinal axis thereby. The lancet is coupled to the pushrod assembly. The housing includes a second end that receives or couples to a sealed end of the pressurized gas canister proximate the lancet such that the electric motor assembly, when energized, causes the pushrod assembly and lancet to translate along the longitudinal axis, pierce a sealed end/diaphragm of the canister, and release pressurized gas through the exhaust port. A system includes the axial piercing mechanism and the pressurized gas canister.

Abstract: Embodiments herein are directed security access. Embodiments include an electronic lock that executes a time-based cryptographic algorithm to compute a time-based access code. The electronic lock compares the time-based access code with a received access code, and grants access to one or more lock features when the time-based access code matches the received access code. Embodiments also include providing an unlock code, including receiving a lock identifier and a user identifier. The lock identifier and the user identifier are sent to a remote computer system, and an access code for the lock is received from the remote computer system. Embodiments also include an electronic lock that receives and verifies an access code that includes a validity start time and a validity end time. When the current time is within the validity start time and the validity end time, the electronic lock grants access to one or more lock features.

Abstract: The present invention relates to methods of detecting the presence of a genetic polymorphism within two or more closely linked, homologous genes, for example ?-thalassemia, in a sample using RT-PCR by subjecting the sample to separate amplification reactions using (a) a pair of forward and reverse primers specific for the head region of each of said two or more closely linked, homologous genes and (b) a pair of forward and reverse primers specific for the tail region of each of said two or more closely linked, homologous genes; and detecting and quantitating the amplification products relative to a control product.
