An algebra A = ⟨A, ∨, ∧, →, 0, 1⟩ is a semi-Heyting algebra if ⟨A, ∨, ∧, 0, 1⟩ is a bounded lattice, and it satisfies the identities: x ∧ (x → y) ≈ x ∧ y, x ∧ (y → z) ≈ x ∧ [(x ∧ y) → (x ∧ z)], and x → x ≈ 1. ℋ denotes the ...

An algebra A=⟨A,→,0⟩, where → is binary and 0 is a constant, is called an implication zroupoid (I-zroupoid, for short) if A satisfies the identities: (x→y)→z≈[(z′→x)→(y→z)′]′ and 0′′≈0, where x′:=x→0, and I denotes the ...

An algebra A= ⟨ A, → , 0 ⟩ , where → is binary and 0 is a constant, is called an implication zroupoid (I-zroupoid, for short) if A satisfies the identities: (x→y)→z≈((z′→x)→(y→z)′)′ and 0 ′ ′≈ 0 , where x′: = x→ 0. An ...

Paraneoplastic neurological syndromes (PNS) are associated with cancer. These syndromes can affect the central nervous system (eg, encephalomyelitis, limbic or brainstem encephalitis, and optic neuritis), the peripheral ...

Activity participation provides a unique context for adolescents and emerging adults to explore interests, talents, and skills and for identity work to occur. Research has found consistent gender differences in the types ...

The professional practice of teachers is shaped and directed by their sense of identity (Grootenboer and Ballantyne, 2010). All teachers have some conception of themselves as educators, but also have some identities that ...

General Fierz-type identities are examined and their well-known connection with completeness relations in matrix vector spaces is shown. In particular, I derive the chiral Fierz identities in a simple and systematic way ...
