On the Characteristic Equations of the Characteristic Polynomial
SIAM Journal on Algebraic Discrete Methods, 1985The characteristic equations for a graph are defined as the system of equations for the coefficients of the characteristic polynomial. The construction of the equations is related to the method of Krylov, and the coefficients of these characteristic equations represent random walks of different length for pairs of vertices.

The characteristics of a biometric
2013 Information Security for South Africa, 2013Biometric implementations have emerged as an improved solution in many spheres of life where security controls are necessary for authentication. However, not all human mannerisms and features can be used as a biometric measure. For example, the movement of an elbow will not satisfy the requirements for a useful biometric.

The Characteristics of Tritanopia
Journal of the Optical Society of America, 1952The paper describes how contact was made with a number of tritanopes through an article published in Picture Post, an illustrated weekly English journal. Seventeen cases of tritanopia were tested and confirmed at the Imperial College, London, and of these, seven made detailed observations on the author’s colorimeter.

A 53 year old man presented with an itchy, red rash on his lower leg after a trip to Brazil. He recalled having been bitten on the right ankle while on a beach and had covered the bite with a plaster. The initial bite mark on the ankle extended by 1-2 cm per day in a serpiginous pattern across the ankle and up the leg (figure)⇓.

Neurological symptoms are reported by more than 80% of hospitalised COVID-19 patients at some point during their disease [1]. These neurological manifestations range from transient, non-life-threatening symptoms to severe and potentially fatal disease states (Table 9.1).

THE CHARACTERISTICS OF THE PSYCHOPATH
American Journal of Psychiatry, 1948obtain as complete and accurate information as possible on the characteristics of the important and troublesome condition known as psychopathic personality. The results we have secured in this investigation will be of definite value in the understanding and in the diagnosis of this type of personality.

Dialysis membrane characteristics are important for an effective and biocompatible dialysis. The properties of a membrane determine the size range of uremic toxins that are eliminated, but are also associated to patient morbidity and mortality. In this paper we describe dialysis the membrane characteristics that could influence the choice of a ...

Characteristics of the Epilepsies
Mayo Clinic Proceedings, 2002Epilepsy is not a specific disease but rather a heterogeneous group of disorders that have in common the characteristic of recurrent, usually unprovoked seizures. Epileptic seizures represent the intermittent and self-limited clinical manifestations (signs and symptoms) that result from abnormally excessive and synchronous activity of neurons. Seizures
