Novel, antibody-based binding agents derived from camelid VHH and human immunoglobulins are described. These binding agents recognize and bind with specificity to Clostridium difficile toxin A and/or toxin B and in some cases exhibit toxin neutralizing activity. These binding agents can be used to treat or prevent primary and recurrent CDI. The binding agents include humanized VHH peptide monomers, linked groups of humanized VHH peptide monomers, humanized VHH peptide monomers joined to antibody Fc domains, and humanized VHH peptide monomers joined to IgG antibodies.

The disclosure relates to a drain filter assembly that attempts to prevent drain blockages from forming by collecting particles such as food, hair and lint prior to entering the drain. In one embodiment, the filter assembly for filtering fluid passing into a drain comprises a housing and a filter. The housing has an upper portion, a lower portion adjacent the drain, and a perimeter surrounding the drain. The perimeter includes a plurality of openings having a height extending from the lower portion. The filter is adjacent the drain. The filter is contained within the perimeter of the housing.

Dimensionally stable nonwoven fibrous webs include a plurality of fibers formed from one or more thermoplastic polyesters and an antishrink additive, preferably in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 12% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. The webs may be used as wipes.

A first device is provided. The first device further comprises an organic light emitting device. The organic light emitting device further comprises an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer further comprises an organic host compound, an organic emitting compound capable of fluorescent emission at room temperature, and an organic dopant compound. The triplet energy of the dopant compound is lower than the triplet energy of the host compound. The dopant compound does not strongly absorb the fluorescent emission of the emitting compound.
摘要:
A method of generating optimized input/output (IO) pair and inter-chip connection combinations for two chips is described. In this method, first and second designs for two chips can be specified. Then inter-chip signals based on the first and second designs can be specified. IO pairs for the first and second chips can be determined based on the inter-chip signals. At this point, electrical contacts between micro-bumps (MBs) of the first and second chips can be formed. Inter-chip paths with through-silicon-vias (TSVs) and MBs of the first and second chips can also be formed. At this point, the costs of assigning the IO pairs to the inter-chip paths can be determined. A cost matrix can be built based on these costs. A bipartite matching algorithm can be applied to the cost matrix to determine the optimized IO pair and inter-chip path combinations.
