Abstract: Exemplary methods of etching a silicon-containing material may include flowing a first fluorine-containing precursor into a remote plasma region of a semiconductor processing chamber. The methods may include flowing a sulfur-containing precursor into the remote plasma region of the semiconductor processing chamber. The methods may include forming a plasma within the remote plasma region to generate plasma effluents of the first fluorine-containing precursor and the sulfur-containing precursor. The methods may include flowing the plasma effluents into a processing region of the semiconductor processing chamber. A substrate may be positioned within the processing region. The substrate may include a trench formed through stacked layers including alternating layers of silicon nitride and silicon oxide. The methods may include isotropically etching the layers of silicon nitride while substantially maintaining the silicon oxide.

Abstract: A patient interface including a positioning and stabilizing structure that is configured to maintain a first seal-forming structure and a second seal-forming structure in a therapeutically effective position. The positioning and stabilizing structure comprises a frame coupled to the plenum chamber. The frame includes a central portion coupled to the plenum chamber outside of the cavity. The frame also includes a pair of arms that extend away from the central portion in a posterior direction past the second seal-forming structure. The pair of arms are more flexible than the central portion. The positioning and stabilizing structure also includes headgear straps coupled to the frame, which configured to provide a tensile force to the first seal-forming structure and to the second seal-forming structure into the patient's face via the frame.

Abstract: A method of at least partially filling an opening in a workpiece made of metal, the opening being at least partially defined by one or more opening walls having one or more opening wall surfaces. The method includes providing an insert bondable with the workpiece, the insert having one or more insert engagement surfaces formed for engagement with the opening wall surface. The opening wall surface and the insert engagement surface are heated to a hot working temperature. The insert is subjected to an engagement motion, to move the insert engagement surface relative to the opening wall surface. While the insert is subjected to the engagement motion, the insert is also subjected to a translocation motion to move the insert at least partially into the opening, for engaging the insert engagement surface with the opening wall surface, for at least partially creating a metallic bond between the insert and the workpiece.

Abstract: Methods and compositions comprising recombinant Arginase I proteins which are capable of depleting the plasma arginine levels in a subject are disclosed. The methods and compositions can be used to modulate the activity of the immune system in a subject. Modulation of the immune system is useful in the treatment of immune disorders and in preventing rejection of a transplanted organ, tissue, or cell. The methods and compositions can also be used to treat a bone condition of a subject.

Abstract: One communication system includes a first die, a second die and a front-end circuit. The first die has an up-converter and a digital baseband (DBB) processing circuit. The second die has a down-converter. The front-end circuit couples an antenna to the first and second dies. Another exemplary communication system includes a first die, a second die and a front-end circuit. The first die performs digital baseband (DBB) processing, and generates a first signal with a higher frequency according to a second signal, wherein the second signal is derived from an output signal of the DBB processing. The second die generates a third signal with a lower frequency according to a fourth signal. The front-end circuit couples the first signal from the first die to an antenna and couples the fourth signal from the antenna to the second die.
