Non-scarring Alopecias in Iranian Patients: A Histopathological Study With Hair Counts

Background and Objective: Non-scarring alopecia is a challenge in the diagnosis and treatment, rarely studied in Asian countries. The current study aimed at evaluating histopathological features including hair count of different subtypes of non-scarring alopecia in Iranian patients.Methods: The current study was conducted on 114 cases diagnosed with...

Local Structure: Subgraph Counts II

Proof. This theorem is a corollary of the (much more general) Kruskal-Katona theorem. The Kruskal-Katona theorem has a very hands-on proof, based on iteratively modifying the graph. We will see a linear-algebraic proof. Let A be the n×n adjacency matrix of G (Auv = 1 if vertex u is adjacent to vertex v, and Auv = 0 otherwise). Note that A is symmetric. It turns out that e and t are both fundame...

Analyzing the laser-light reflection from human hair fibers. II. Deriving a measure of hair luster.

Hair shine or luster is perceived as an important, though analytically somewhat elusive, attribute of beauty, primarily associated with clean and healthy hair. Principles for the assessment of hair luster are developed that are consistent with the practical situation. These principles are related to the components of light, specularly and diffusely reflected from single hair fibers, as measured...
