Medical Education Online, 2016 The training of physicians in the past century was based primarily on responsibility and the chain-of-command. Those with the bulk of that responsibility in the fields of pediatrics and internal medicine were residents. Residents trained the medical students and supervised them carefully in caring for patients.

Boolean Functions and Permanents of Sylvester Hadamard Matrices
Mathematics, 2021 One of the fastest known general techniques for computing permanents is Ryser’s formula. On this note, we show that this formula over Sylvester Hadamard matrices of order 2m, Hm, can be carried out by enumerating m-variable Boolean functions with an ...

The Dittert's function on a set of nonnegative matrices
International Journal of Mathematics and Mathematical Sciences, 1990 Let Kn denote the set of all n×n nonnegative matrices with entry sum n. For X∈Kn with row sum vector (r1,…,rn), column sum vector (c1,…,cn), Let ϕ(X)=∏iri+∏jcj−perX. Dittert's conjecture asserts that ϕ(X)≤2−n!/nn for all X∈Kn with equality iff X=[1/n]n×n.

A systematic framework for analyzing the dynamic effects of permanent and transitory shocks [PDF]
, 2001 This paper proposes a systematic framework for analyzing the dynamic effects of permanent and transitory shocks on a system of n economic variables. We consider a two-step orthogonolization on the residuals of a VECM with r cointegrating vectors.

Per-Spectral Characterizations Of Some Bipartite Graphs
Discussiones Mathematicae Graph Theory, 2017 A graph is said to be characterized by its permanental spectrum if there is no other non-isomorphic graph with the same permanental spectrum. In this paper, we investigate when a complete bipartite graph Kp,p with some edges deleted is determined by its ...

Proceedings of the American Mathematical Society, 1972 A permanent group is a group of nonsingular matrices on which the permanent function is multiplicative. Let A ∘ B A \circ B denote the Hadamard product of matrices A and B. The set of groups G of nonsingular n × n n \times n matrices which contain the diagonal group
