Abstract: A semiconductor die includes a circuit, a plurality of metal layers, a first sawbow line coupled to the circuit, and a second sawbow line coupled to the circuit. The first sawbow line is hidden under a first metal layer of the plurality of metal layers when the first sawbow line is in a cut state. The second sawbow line is hidden under the first metal layer or a second metal layer of the plurality of metal layers when the second sawbow line is in a cut state. The first sawbow line and the second sawbow line are on different ones of the plurality of metal layers. A number of pull-down or pull-up resistors may be included to set the logical states of the sawbow lines, in order to disable a predetermined mode of operation of the die when a wafer including the die is cut. The sawbow lines may carry a variety of types of signals (e.g., analog, digital, random, ground, supply) that makes the nature and value of them extremely hard to detect/hack.

Abstract: A system for bracing a reciprocating shaft having a first shaft portion that moves along a long axis with respect to a second shaft portion and a short axis orthogonal to the long axis. The first shaft portion moves past a switch in a first direction to disengage the switch and past the switch in a second direction to engage the switch. A bracing member is carried by the switch and has a tip that, when the switch is engaged, is located immediately adjacent and laterally braces the second shaft portion by limiting movement of the second shaft portion along the short axis. When the switch is disengaged, the tip of the bracing member is not located immediately adjacent the shaft.

Abstract: A hot melt adhesive made from a blend of a polypropylene-based polymer, a polyolefin elastomer, and an amorphous polyolefin. These adhesives exhibit excellent molten and pre-set flow allowing them to wet out substrates yet develop properties needed to form and maintain strong bonds making them useful for hygiene, construction, and packaging applications.

Abstract: A system and method for maintaining a laser impinging on a laser detector assembly includes determining a location of the laser from a rotating laser transmitter impinging on a laser sensor. A current position of the laser sensor along a mast of the laser detector assembly is determined and a new position for the laser sensor along the mast is determined based on the location of the laser impinging on the laser sensor and a current position of the laser sensor. The laser sensor is then moved to the new position. The system and method provide an effectively long working range of the laser detector assembly by moving the laser sensor along the mast of the laser detector assembly. An inertial measurement unit is used to calculate position information in the period between laser strikes.

Abstract: A method for determining an elevation of a laser detector assembly includes calculating an estimated elevation of a laser detector assembly based on data from an inertial measurement unit and a detected laser strike. The estimated elevation is then output. A detected elevation of the laser detector assembly is calculated based on the detected laser strike and the detected elevation is output in response to the detected laser strike. The estimated elevation is calculated and output between outputs of detected elevations.

Abstract: A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.

Abstract: An electrophysiology catheter has an elongated catheter shaft and a distal assembly with a flex circuit and a support member on which the flex circuit is supported in a generally cylindrical form. The support member has a post extending longitudinally through the cylindrical form of the flex circuit which delivers irrigation fluid into the cylindrical form. The post can be configured to define multiple irrigation chambers within the distal assembly. One or more flow directors movable in the post selectively direct irrigation fluid within the distal assembly. Apertures in the flex circuit allow the irrigation fluid to exit to outside the distal assembly.

Abstract: Quantum dot semiconductor nanoparticle compositions that incorporate ions such as zinc, aluminum, calcium, or magnesium into the quantum dot core have been found to be more stable to Ostwald ripening. A core-shell quantum dot may have a core of a semiconductor material that includes indium, magnesium, and phosphorus ions. Ions such as zinc, calcium, and/or aluminum may be included in addition to, or in place of, magnesium. The core may further include other ions, such as selenium, and/or sulfur. The core may be coated with one (or more) shells of semiconductor material. Example shell semiconductor materials include semiconductors containing zinc, sulfur, selenium, iron and/or oxygen ions.

Abstract: A system and a method are disclosed for recommending podcasts. In an embodiment, the system detects a podcast request, and responsively determines whether a profile of the user indicates consumption by the user of podcasts. Responsive to determining that the profile does not indicate consumption by the user of podcasts, the system determines music preferences of the user based on data of the profile, and generates a podcast seed based on the music preferences. The system selects a podcast recommendation based on the podcast seed, and provides the podcast recommendation to the user. The system receives a selection of the podcast recommendation by the user, and responsively plays back a podcast corresponding to the podcast recommendation.

Abstract: Certain dithio-compounds have been found to be superior capping ligands for quantum dot (QD) nanoparticles. Example dithio-ligands include dithiocarbamate ligands. These strongly binding ligands are capable of coordinating to both positive and negative atoms on the surface of the nanoparticle. The ligands are bi-dentate and thus their approach to the QD surface is not as sterically hindered as is the approach of mono-dentate ligands. These ligands can therefore completely saturate the QD surface.

Abstract: Data processing can be managed in a distributed computing environment (DCE). In one example, the DCE can receive a sequence of computing operations to be consecutively executed in the DCE. For each computing operation in the sequence, the DCE can receive input data for the computing operation, partition the input data into subsets, and determine whether the computing operation is linear or non-linear. The DCE can then apply different processing techniques to the subsets depending on whether the computing operation is linear or non-linear.
