Local page writes via pre-staging buffers for resilient buffer pool extensions
Methods for local page writes via pre-staging buffers for resilient buffer pool extensions are performed by computing systems. Compute nodes in database systems insert, update, and query data pages maintained in storage nodes.

Bow grip aid
Shooting accuracy in archery may be greatly improved by increasing the precision and repeatability in which an archer establishes “anchor points,” which are contact points between the archer and a drawn bow and arrow at a moment of launch. One such contact point is the hand gripping the bow grip. The invention provides a bow grip aid which enables an archer to repeatably grip the same location of the bow grip and maintain consistent grip firmness from one shot to the next. Reducing variances of this aspect of the archer's form benefits the archer by reducing variances between the archer's sighting process and determination of point of aim, and the impact point of the arrow on its target. The invention helps archers grip a bow more consistently so they can consistently place each arrow where they want it to go. |

Fusion-formable glass-based articles including a metal oxide concentration gradient
A glass-based article including a first surface and a second surface opposing the first surface defining a thickness (t) of about 3 millimeters or less (e.g., about 1 millimeter or less), and a stress profile, wherein all points of the stress profile between a thickness range from about 0·t up to 0.3·t and from greater than about 0.7·t to t, comprise a tangent with a slope having an absolute value greater than about 0.1 MPa/micrometer. In some embodiments, the glass-based article includes a non-zero metal oxide concentration that varies along at least a portion of the thickness (e.g., 0·t to about 0.3·t) and a maximum central tension of less than about 71.5/√(t) (MPa). In some embodiments, the concentration of metal oxide or alkali metal oxide decreases from the first surface to a point between the first surface and the second surface and increases from the point to the second surface. The concentration of the metal oxide may be about 0.05 mol % or greater or about 0.5 mol % or greater throughout the thickness. Methods for forming such glass-based articles are also disclosed. |

Manufacturing apparatus and manufacturing method of porous glass base material
A manufacturing apparatus of porous glass base material includes deposition apparatuses that manufacture a porous glass base material by generating raw material particles from vaporized raw material compounds in an oxyhydrogen flame, and then depositing the generated raw material particles on a rotating starting material. The manufacturing apparatus includes a storage container that stores liquid raw material compounds for each compound, a vapor generation mechanism that vaporizes the raw material compounds, and a gas channel that supplies the vaporized raw material compounds to the deposition apparatuses. The gas channel includes a common gas channel shared to supply vaporized raw material compounds to the plurality of deposition apparatuses, and individual gas channels branched off from the common gas channel to supply vaporized raw material compounds to each of the deposition apparatuses individually. Each of the individual gas channels has a flow controller, a steam valve, and a valve. |
