- ?o??Tarski preservation theorem
The o &ndash Tarski theorem is a theorem in model theory , a branch of mathematics that states that the set of formulas preserved under taking substructures are the universal formulas math forall 1 math formulas . Its definition as given in Wilfrid Hodges Hodges , A Shorter Model Theory, 2003 is as follows Let math T math be a theory in a first order language math L math and math Phi bar x math a set of formulas of math L math . The set of sequence of variables math bar x math need not be finite. Then the following are equivalent If math A math and math B math are models of math T math , math A subseteq B math , math bar a math is a sequence of elements of math A math and math B models bigwedge Phi bar a math , then math A models bigwedge Phi bar a math . br math Phi math is preserved in substructures for models of math T math math Phi math is equivalent modulo math T math to a set math Psi bar x math of math forall 1 math formulas of math L math . The math forall 1 math formulas is the set of first order formulas of the form math forall x 1 dots forall x n bigwedge Psi math , i.e. the set of math Pi 1 math formulas see the arithmetical hierarchy . Note that this property fails for finite model theory finite models .

- Negational normal form
merge Negation normal form date February 2012 Negative normal form is way to represent the formula by keeping the negation symbol only to the literals. If and are boolean formulas, then logical conjunction math wedge math , logical disjunction math vee math , negation math neg math , implication math rightarrow math are all boolean formulas. The boolean formulas are made up of literals which are propositional atoms. A formula can be converted to the NNF by simply moving the negations across braces either using De Morgan s laws or the property that math neg neg math is itself.

- Bernays?Schönfinkel class
The Bernays Sch nfinkel class also known as Bernays Sch nfinkel Ramsey class of formulas, named after Paul Bernays and Moses Sch nfinkel and Frank P. Ramsey , is a decidable fragment of first order logic formulas. It is the set of satisfiable formulas which, when written in prenex normal form , have an math exists forall math quantifier prefix and do not contain any function symbols. This class of logic formulas is also sometimes referred as effectively propositional EPR since it can be effectively translated into propositional logic formulas by a process of grounding or instantiation.

- Amino acid-based formula
An amino acid based formula , also known as an elemental formula , is a type of hypoallergenic infant formula made from individual amino acids . Amino acids are the building blocks of protein and together they form the protein requirements in formula needed for growth and development. The amino acids are in the simplest form, making it easy for the body to process and digest. Because infants and children have different nutritional needs, amino acid based formulas are typically formulated either for infants 0 1 years of age or for children 1 10 years of age. Indications Amino acid based formulas are most commonly indicated for Milk or soy protein allergy Multiple food protein intolerance Food protein allergy induced Eosinophilic esophagitis and Gastroesophageal reflux disease Other medical conditions requiring an amino acid based diet, such as Short bowel syndrome and Transition from parenteral to enteral nutrition Reimbursement br Unlike milk based, soy based, and hydrolysate formulas, amino acid based formulas fall under the FDA classification of exempt infant formulas or medical foods. Therefore, 11 states currently require that insurance companies reimburse families for amino acid based formulas. The states are Arizona, Connecticut, Illinois, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, New York, and Rhode Island. The details of each law are different. Some families may also qualify for Special Supplemental Nutrition Program for Women, Infants and Children WIC or private assistance programs.

- Propositional variable
In mathematical logic , a propositional variable also called a sentential variable or sentential letter is a Variable mathematics variable which can either be true or false . Propositional variables are the basic building blocks of propositional formula s, used in propositional logic and higher logics. Formulas in logic are typically built up recursively from some propositional variables, some number of logical connective s, and some logical quantifier s. Propositional variables are the atomic formula s of propositional logic. For example, in a given propositional logic, we might define a formula as follows Every propositional variable is a formula. Given a formula X the negation X is a formula. Given two formulas X and Y , and a binary connective b such as the logical conjunction , then X b Y is a formula. Note the parentheses. In this way, all of the formulas of propositional logic are built up from propositional variables as a basic unit. Propositional variables are represented as nullary Predicate mathematical logic predicates in first order logic .
