The apparatus can include a first transistor, a second transistor, a first interconnect structure, a second interconnect structure, and a third interconnect structure. The local interconnect structure can be coupled to gate terminals of the first and second transistors and routed at a same interconnect level as reference metal lines coupled to ground and a power supply voltage. The first interconnect structure can be coupled to a source/drain terminal of the first transistor and routed above the local interconnect structure. The second interconnect structure can be coupled to a source/drain terminal of the second transistor and routed above the local interconnect structure. The third interconnect structure can be routed above the local interconnect structure and at a same interconnect level as the first and second interconnect structures.

Abstract: A hydroponic cultivation apparatus, a system and a method for facilitating hydroponic cultivation is disclosed. The hydroponic cultivation apparatus includes a reservoir, a plinth, a grow tray with a grow tray lid, and a docking with coupler. The reservoir, placed upon the plinth, is located at a higher position adjacent to the grow tray for optimizing liquid circulation from the reservoir to the grow tray and vice-versa using one or more pipes, a solenoid valve and a pump. The base further includes a dock coupled to the grow tray for providing an electrical connectivity to the grow tray and simultaneously allowing the liquid to flow through the grow tray without being leaked. Further, the apparatus is having a roof which is provided with sources of illumination for providing light required for plant growth.

Abstract: Cathode materials comprising composites of vanadium sulfide and sulfur are provided along with methods of making same. Solid-state lithium sulfur batteries comprising such cathode materials are also provided.

Abstract: Disclosed is an electrochemical cell comprising a lithium-based anode and a sulfur-based cathode and an electrolyte, wherein the cathode material comprises a polymeric binder, wherein the binder comprises ammonium functional groups. In one aspect, the polymeric binder comprises ammonium chloride functional groups.

Abstract: Examples of the disclosure are directed to systems and methods of using natural language processing techniques to automatically assign metadata to articles as they are published. The automatically-assigned metadata can then feed into the algorithms that calculate updated causation scores for agent-outcome hypotheses, powering live visualizations of the data that update automatically as new scientific articles become available.

Abstract: A toothbrush includes a handle and a head connected to an end of the handle. The head has a surface. A plurality of bristles are mounted on the head so the bristles extend from the surface on only one side of the head. The plurality of bristles are arranged in a plurality of sets including first, second, and third sets. The bristles of each of the first, second, and third sets are substantially parallel to other bristles in the same respective set. The bristles in the first and third sets are oriented to angle outwardly from the bristles in the second set as they extend away from the surface.

Abstract: A hand-held hair styling device permits precise introduction of a curl into the hair. A selectively actuatable drive system drives rotation of one or more rotatable bases, each carrying a hair styling element on it. The drive system includes a transmission connecting an actuator to the rotatable base to transmit the movement of the actuator in one direction into rotation of the rotatable base in a first direction. The transmission is configured to prevent rotation of the rotatable base in a second direction opposite to the first direction upon movement of the actuator in an opposite direction. In another aspect the transmission is configured to produce a single 360° rotation of the rotatable base upon movement of the actuator in the first direction.

Abstract: A hand-held hair styling device includes a body having a front side, a back side, and a side edge extending between the front and back sides. A rotatable base is mounted on the body for rotation relative to the body about an axis of rotation. The rotatable base has a surface facing generally away from the body. The axis of rotation of the rotatable base extends substantially perpendicular to a longitudinal axis of the body. At least one hair styling element is mounted on the surface of the rotatable base for rotation with the rotatable base. The hair styling element includes a twisted elongate member.

Abstract: A hanger bar for mounting a hanging file folder on a pair of support rails includes a body having a top, a bottom, and opposite longitudinal ends. The body includes a first section having a length extending longitudinally across the body and a height extending from the top of the body toward the bottom of the body. A second section has a length extending longitudinally across the body and a height extending from the first section of the body toward the bottom of the body. A third section has a length extending longitudinally across the body and a height extending from the second section of the body to the bottom of the body. The first section is angled with respect to a vertical axis when the body is positioned in a vertical orientation.

Abstract: A hanger for hanging a binder containing loose-leaf pages in a hanging drawer system has first and second opposed hooks configured to be secured to a notebook spine.
