Data partitioning based on estimated growth
During a first delta time period, monitoring a growth in a number of records and determining a highest-growth partition in the database. The highest-growth partition is divided into subranges. During a second delta time period, a growth is monitored for each subrange. For the subrange with a greatest growth, the subrange is subdivided into sub-subranges and a growth determined for each sub-subrange. The monitoring and the determining is repeated and further subdivisions made of divisions having the highest growths until growths have been recorded for N delta time periods. For each of the N delta time periods, weighted growths are determined for each subdivision. Expected record counts are determined for each of the divisions that are expected for a subsequent time period spanning the N delta time periods. Based on the expected record counts, a partition split point within the highest-growth partition is determined, and the highest-growth partition is split into two partitions. |

Terpolymerization of carbon monoxide, an olefin, and an epoxide
In various embodiments, the present invention is directed to terpolymers of carbon monoxide (CO), olefins (alkenes), and epoxides, as well as related methods and catalysts for their making and use. These terpolymer chains are comprised of ketone repeat units, ester repeat units, and ether repeat units. The additional presence of the ester repeat units and ether repeat units have the effect of lowering terpolymer melt temperature relative to that of similar polyketone, thus separating melt temperature from decomposition temperature, making it suitable for melt processing. In a single reaction mixture, the same metal catalyst that polymerizes CO with olefins also incorporates epoxide monomers into the terpolymer in the form of ester or ester and ether linkages. As a part of the terpolymer chain, the ester groups can undergo hydrolysis, rendering these terpolymer compositions hydrolytically degradable. |

Pyridine derivative
The problem to be solved by the present invention is to provide a compound suitable for a pharmaceutical composition, specifically a pharmaceutically composition for treating nocturia. The inventors have assumed that inhibition of nocturnal activity of placental leucine aminopeptidase (P-LAP), i.e. aminopeptidase that cleaves AVP, would maintain and/or increase an endogenous AVP level to enhance the antidiuretic effect, which would contribute to a decreased number of nocturnal voids, and have extensively studied compounds which inhibit P-LAP. As a result, the inventors have found that (2R)-3-amino-2-{[4-(substituted pyridine)-2-yl]methyl}-2-hydroxy-propanoic acid derivatives have excellent P-LAP inhibitory activity. The inventors have evaluated antidiuretic effects in water-loaded rats and have found that the compounds increase endogenous AVP levels by inhibiting P-LAP and consequently reduce urine production. The present invention therefore provides compounds expected to be used as an agent for treating nocturia based on P-LAP inhibition. |

Batcher gate for asphalt silo handling
An asphalt batcher has top and bottom coupling flanges that bolt to a silo, conveyor, and related apparatus. The batcher includes a receptacle for selectively receiving and retaining materials. The receptacle has a material splitter to divide material flowing into the batcher into at least two separate funnels. Adjacent to the outlet, each of the funnels have a receptacle side wall opening. At least one pair of removable batcher gate assemblies are readily inserted into and removed from the receptacle side wall openings. Each batcher gate assembly has a batcher gate door. The pair of batcher gate doors are placed offset from center, closer to the opposed outer walls, and open toward each other and therefore the center to guide materials from the batcher receptacle body out of the batcher and into the silo center. Receptacle side wall access doors provide inspection of and access to the two funnels. |

Lidded container and container used therefor
The present invention provides a lidded container which, even when a flange portion of the container warps during microwave heating, can prevent a contact between the flange portion and a lid and allows steam to pass from a steam escape mechanism. The lidded container is provided with a container having an opening and a lid which covers the opening and is joined to the container. The container is provided with a bottom portion, a side portion standing upright from the bottom portion, and a flange portion which is continuously connected to an upper portion of the side portion and includes a first plane. A circumferential seal portion is formed between the lid and the first plane of the flange portion. The seal portion is provided with a main seal portion and a protruding seal portion protruding inward with respect to the main seal portion. At least one of the flange portion and the lid is formed with a contact suppression mechanism for suppressing a contact between the flange portion and the lid, which is provided outside the protruding seal portion at a position corresponding to at least the protruding seal portion. |
