Merge to Memory model computing date February 2010 Cleanup date November 2009 Memory ordering is a group of properties of the modern microprocessor s, characterising their possibilities in memory operations reordering. It is a type of out of order execution . Memory reordering can be used to fully utilize different CPU cache cache bank cache and memory bank s. On most modern uniprocessors memory operations are not executed in the order specified by the program code. But from the programmer s point of view, all operations appear to have been executed in the order specified, with all inconsistencies hidden by hardware. In compilers Compilers can also reorder operations when? to hide memory latencies. There are memory barriers, which prevent compiler to move memory operations around it. In SMP microprocessor systems There are several memory consistency models for Symmetric multiprocessing SMP systems sequential consistency All reads and all writes are in order relaxed consistency Some types of reordering are allowed Loads can be reordered after Loads for better working of cache coherency ...

Charge ordering CO is a first or second order phase transition occurring mostly in strongly correlated materials such as transition metal oxides or organic conductors . Due to the strong interaction, the charge physics charge is localized on different sites leading to a disproportionation and an Order crystal lattice ordered superlattice . It appears in different patterns ranging from vertical to horizontal stripes to a checkerboard like pattern, and it is not limited to the two dimensional case.

Not to be confused with partial evaluation . In computer science , partial application or partial function application refers to the process of fixing a number of arguments to a function, producing another function of smaller arity . Given a function math scriptstyle f colon X times Y times Z to N math , we might fix or bind the first argument, producing a function of type math scriptstyle text partial f colon Y times Z to N math . Evaluation of this function might be represented as math f partial 2, 3 math . Note that the result of partial function application in this case is a function that takes two arguments. Motivation Intuitively, partial function application says if you fix the first parameter computer science argument s of the function, you get a function of the remaining arguments . For example, if function div stands for the division operation x y , then div with the parameter x fixed at 1 i.e. div 1 is another function the same as the function inv that returns the multiplicative inverse of its argument, defined by inv y 1 y . The practical motivation for partial application is that very often the functions obtained by supplying some but not all of the arguments to a function ... . Partial application makes it easy to define these functions, for example by creating a function that represents ... form by default.

In functional analysis a partial isometry is a linear map W between Hilbert spaces H and K such that the restriction of W to the orthogonal complement of its kernel algebra kernel is an isometry . We call the orthogonal complement of the kernel of W the initial subspace of W , and the range of W is called the final subspace of W . Any unitary operator on H is a partial isometry with initial and final subspaces being all of H . For example, In the two dimensional complex Hilbert space C sup 2 sup the matrix math begin bmatrix 0 & 1 0 & 0 end bmatrix math is a partial isometry with initial subspace math 0 oplus mathbb C subseteq mathbb C oplus mathbb C math and final subspace math mathbb C oplus 0 . math The concept of partial isometry can be defined in other equivalent ways. If U is an isometric map defined on a closed subset H sub 1 sub of a Hilbert space H then we can define an extension W of U to all of H by the condition that W be zero on the orthogonal complement of H sub 1 sub . Thus a partial isometry is also sometimes defined as a closed partially defined isometric map. Partial isometries are also characterized by the condition that W W or W W is a projection. In that case, both W W and W W are projections of course, since orthogonal projections are self adjoint, each orthogonal projection is a partial isometry . This allows us to define partial isometry in any C algebra as follows If A is a C algebra, an element W in A is a partial isometry if and only if W W or W W is a projection ....

Partial hospitalization , also known as PHP from Partial Hospitalization Program , is a type of program used to treat mental illness and substance abuse . In partial hospitalization, the patient continues to reside at home, but commutes to a treatment center up to seven days a week. Since partial hospitalization focuses on overall treatment of the individual, rather than purely safety, the program is not used for acutely suicidal people. The pioneer of partial hospital programs, Dr. Albert E. Moll , ref The News and Courier Center Gives Day Mental Care , page 1. Charleston, SC, May 13, 1952. ref believed that some patients would be unable to be away from their families or from work and that these programs would reduce the cost of long term care. Partial hospitalization should not be confused with day treatment which is sometimes referred to as partial hospitalization. Partial hospitalization is provided on or in affiliation with a hospital. This separates them from partial care or day treatment which are either non profit or profit agencies not affiliated with a hospital. Treatment during a typical day may include group therapy , psychotherapy individual therapy ,and psychopharmacology psychopharmacological assessments and check ins.

In statistics , high leverage points are those that are outlier s with respect to the independent variables . leverage statistics Leverage point s are those that cause large changes in the parameter estimates when they are deleted. Although a leverage point will typically have high leverage, a high leverage point is not necessarily an influential point. The leverage statistics leverage is typically defined as the diagonal of the hat matrix math H X X X 1 X . , math Partial leverage is used to measure the contribution of the individual independent variables to the leverage of each observation. That is, if h sub i sub is the i sup th sup row of the diagonal of the hat matrix, the partial leverage is a measure of how h sub i sub changes as a variable is added to the regression model. The partial leverage is computed as math left mathrm PL j right i frac left X j bullet j right i 2 sum k 1 n left X j bullet j right k 2 math where j index of independent variable i index of observation X sub j · j sub errors and residuals in statistics residuals from regressing X sub j sub against the remaining independent variables Note that the partial leverage is the leverage of the i sup th sup point in the partial regression plot for the j sup th sup variable. Data points with large partial leverage for an independent variable can exert undue influence on the selection of that variable in automatic regression model building procedures.

In Relational database management system databases , a partial index , also known as filtered index is an Index database index which has some condition applied to it so that it includes a subset of Row database row s in the Table database table . This allows the index to remain small, even though the table may be rather large, and have extreme selectivity. Suppose you have a transaction table where entries start out with STATUS A active , and then may pass through other statuses P for pending, W for being worked on before reaching a final status, F , at which point it is no longer likely to be processed again. In PostgreSQL, a useful partial index might be defined as create index partial status on txn table status where status in A , P , W This index would not bother storing any of the millions of rows that have reached final status, F , and would allow queries looking for transactions that still need work to efficiently search via this index. Similarly, a partial index can be used to index only those rows where a column is not null, which will be of benefit when the column usually is null. create index partial object update on object table updated on where updated on is not null This index would allow the following query to read only the updated tuples select from object table where updated on is not null order by updated on It is not necessary that the condition be the same as the index ... create index partial salary on employee age where salary 2100 Support In Microsoft SQL ...
