A home health aide (HHA) provides in-home care for patients who need assistance with daily living beyond what family or friends can provide. Patients include those who have a physical or mental disability, are recovering from an injury or surgery, have a chronic illness, or are advanced in age.
Polymerase cycling assembly (or PCA, also known as Assembly PCR) is a method for the assembly of large DNA oligonucleotides from shorter fragments. The process uses the same technology as PCR, but takes advantage of DNA hybridization and annealing as well as DNA polymerase to amplify a complete sequence of DNA in a precise order based on the single stranded oligonucleotides used in the process.
The Permanent Court of Arbitration (PCA) is a non-UN intergovernmental organization headquartered at the Peace Palace, in The Hague, Netherlands.Unlike a judicial court in the traditional sense, the PCA provides administrative support in international arbitrations involving various combinations of States, State entities, international organizations and private parties.

Principal component analysis (PCA) is a linear dimensionality reduction technique with applications in exploratory data analysis, visualization and data preprocessing.. The data is linearly transformed onto a new coordinate system such that the directions (principal components) capturing the largest variation in the data can be easily identified.
Interaction between the bait and the prey proteins brings the fragments of the reporter protein in close proximity to allow them to form a functional reporter protein whose activity can be measured. This principle can be applied to many different reporter proteins and is also the basis for the yeast two-hybrid system, an archetypical PCA assay.
Pyroglutamic acid (also known as PCA, 5-oxoproline, pidolic acid) is a ubiquitous but understudied natural amino acid derivative in which the free amino group of glutamic acid or glutamine cyclizes to form a lactam. [1] The names of pyroglutamic acid conjugate base, anion, salts, and esters are pyroglutamate, 5-oxoprolinate, or pidolate.
Accused UnitedHealthcare CEO killer Luigi Mangione spent his first night back in the Big Apple under the same NYC federal prison as disgraced rap mogul Sean "Diddy" Combs.
Houston Housing Authority (HHA), formerly Housing Authority of the City of Houston (HACH), is the public housing authority in Houston, Texas. The Mayor of Houston appoints the board of directors of the HHA, but it itself is not a department of the city government.
