Abstract: A communication system personality provisioning system includes a communication system included in a computing system and coupled to a management system. The communication system stores authentication information in a UEFI database of a UEFI system in the communication system. The communication system receives a first operating software image and application/service from the management system, authenticates the first operating software image and application/service via first secure initialization operations performed by the UEFI system using the authentication information and, in response, installs the first operating software image and application/service on the communication system.

Abstract: A graph-based data multi-operation system includes a data multi-operation management subsystem coupled to an application and accelerator subsystems. The data multi-operation management subsystem receives a data multi-operation graph from the application that identifies first data and defines operations for performance on the first data to transform the first data into second data. The data multi-operation management subsystem assigns each of the operations to at least one of the accelerator systems, and configures the accelerator subsystems to perform the operations in a sequence that transforms the first data into the second data, When the data multi-operation management subsystem determine a completion status for the performance of the operations by the accelerator subsystems, it transmits a completion status communication to the application that indicates the completion status of the performance of the plurality of operations by the plurality of accelerator subsystems.

Abstract: Class C fly ash-based cementitious materials, concretes, and related techniques are disclosed. In accordance with some embodiments, an activated class C fly ash-based cementitious material may be produced by intergrinding class C fly ash (e.g., classified to remove quartz and/or other contaminants and, thus, increase the reactive materials present), an activator, sodium citrate, borax, and a polycarboxylate material. The class C fly ash may have an amorphous glass content of about 60 wt % or more, a calcium oxide (CaO2) content of about 20 wt % or more, and a quartz content of about 10 wt % or less. The activator may be a chemical which reacts with class C fly ash to form strätlingite structures therein when introduced with water. In some cases, the cementitious material may be provided as an all-in-one powder blend. In some cases, techniques disclosed herein may be utilized in providing a fast-setting flowable fill material.

Abstract: A system and computer-readable storage medium perform a method for contextual inferring capacity for triggering a financial transaction by monitoring, via user device(s), objective contextual data of location, temporal, and volitional transaction information associated with an authorized user of a financial system. Subjective contextual data of personal calendar events, physiological data, and pacing of user interactions with the user device(s) is monitored. The objective and subjective contextual data is analyzed to create scenario(s) correlated with performing a volitional transaction. If not predictive a volitional transaction, a layer of security protocol is added for authentication prior to executing the volitional transaction. In response to determining that the current context is predictive of a volitional transaction, a determination is made whether the subjective contextual data satisfies criterion for incapacity to perform a volitional transaction.

Abstract: Methods and systems for reclaiming materials from a mixed waste landfill containing coal combustion byproducts (CCBs) are disclosed. The methods and systems can be used to reclaim CCBs from ponds or dry landfills by obtaining mixed waste, crushing the mixed waste to form crushed mixed waste, drying the crushed mixed waste to form dried crushed mixed waste, and combining the dried crushed mixed waste with other compounds to form a blend. The blends can then be incorporated into a cement material, which may be used to form concrete.

Abstract: An ablation catheter is equipped with an irrigated tip electrode that can stimulate tissue in, e.g., a renal artery to help identify the location of a renal nerve. High-frequency stimulation of the renal nerve causes a decrease in the blood pressure of the patient thereby indicating that a renal nerve is nearby. The ablation catheter is used to ablate the renal nerve using radiofrequency, ultrasound, microwave energy or cryogenic cooling. Irrigation from the irrigated tip electrode may be used to decrease damage to cells in the wall of the lumen of the renal artery other than the renal nerve, such as the endothelial cells. In order to treat atrial fibrillation an ablation catheter would be used to isolate one or more pulmonary veins.

Abstract: A self-releasing latch for a firearm charging handle is disclosed. The charging handle self-releasing latch includes a roller arm and a roller wheel. The roller arm includes a roller wheel at one end and a protrusion at the other end for engaging a spring. Further, a rocker feature provides a pivot point about midway of the roller arm. The roller wheel of the self-releasing latch engages with a detent or groove under spring force to hold the charging handle in the latched state. Aspects of the charging handle self-releasing latch are that it allows substantially frictionless operation of the charging handle without any manual actuation of levers and/or latches, and that it allows ambidextrous operation of the charging handle of an AR-style weapon platform. Further, a method is provided of retrofitting an existing firearm with the presently disclosed charging handle self-releasing latch.

Abstract: A catheter includes an elongated body, a distal assembly with a shape-memory member defining a generally helical form, and a control handle. The control handle may be adapted to actuate a deflection puller wire for deflecting a portion of the elongated body and a contraction wire for contracting the generally helical form. The generally helical form carries irrigated ablation ring electrodes. A nitinol support member with shape memory extends through the distal assembly and into the elongated body to provide the helical form. The support member may have a varying stiffness along its length, for example, a decreasing stiffness toward a distal end of the support member. The support member can also be hollow so that it can receive a mandrel whose stiffness is greater than that of the support member.

Abstract: A method for ablating tissue in or around the heart to create an enhanced lesion is provided. The distal end of a catheter including a needle electrode at its distal end is introduced into the heart. The distal end of the needle electrode is introduced into the tissue. An electrically-conductive fluid is infused through the needle electrode and into the tissue. The tissue is ablated after and/or during introduction of the fluid into the tissue. The fluid conducts ablation energy within the tissue to create a larger lesion than would be created without the introduction of the fluid.
