In insects, the frequency distribution of the measurements of sclerotized body parts is generally used to classify larval instars and is characterized by a multimodal overlap between instar stages. Nonparametric methods with fixed bandwidths, such as histograms, have significant limitations when used to fit this type of distribution, making it difficult to identify divisions between instars. Fi...

Skull morphology is fundamental to evolution and the biological adaptation of species to their environments. With aquaculture fish species, head size is also important for economic reasons because it has a direct impact on fillet yield. However, little is known about the underlying genetic basis of head size. Catfish is the primary aquaculture species in the United States. In this study, we per...

An anatomic study was conducted on 49 dried cadaveric humeri and 24 dried cadaveric scapula to ascertain the variability of the following parameters: humeral neck angle, humeral head retroversion, humeral head medial offset, humeral head posterior offset, humeral head diameter glenoid height, glenoid width, and the glenoid height to width ratio. For verification purposes, the results of this st...

We prove that evaluating a Boolean decision tree of height h requires ( h m+log h ) time on any EREW PRAM with communication width m and any number of processors. Since this function can be easily computed in time O( p h) on a CREW PRAM with communication width one using 2 O(h) processors, this gives a separation between the two models whenever the EREW PRAM has communication width m 2 o( p h)....

Sperm morphology is unique among the known cells and 3 major parts can be immediately distinguished: head, midpiece and tail. Normal sperm exhibit an oval-shaped head with a regular outline and a cap (acrosome) covering more than one-third of the head surface. The midpiece is slender, less than one third of the width of the head, straight and regular in outline. The tail is slender, uncoiled an...

cephalometry is an important branch of anthropology in which the dimensions of head and face can be determined. these dimensions are used to show indexes for studying brain growth and formation of all types of head and face. indexes are vary from 65 to 95 for head and 65 to105 for face, which are used to determine 4 international anatomic types of head and 5 international anatomic types of face...

With the use of conventional anatomical dissection, radiography, digital and statistical analysis, morphometry and skeletopy of the pancreas was carried out in 60 human foetuses of both sexes (28 female, 32 male) between the 17th and 40th week of intrauterine life. The material was fixed in a 10% formalin solution. The age of the foetuses was determined by crown-rump (CR) length measurement on ...

Calculations of the magnetic fields emanating from a recorded surface that contains an infinite number of identical tracks are presented. The solutions are obtained by assuming that the magnetization is uniform through the thickness of the film and can be represented by Fourier series in the other two dimensions. Solutions are obtained for both longitudinal and vertical recording. To make these...

BACKGROUND The posterior interosseous nerve (PIN) can be difficult to locate within the radial tunnel. The deep branch of the radial nerve (DBRN) enters the supinator muscle after passing under the arcade of Fröhse. It courses through the superficial portion of the supinator muscle to exit distally as the PIN. Anatomic landmarks could facilitate diagnosis and treatment of radial tunnel syndrome...
