Uniquely monopolar-partitionable block graphs

open access: yes, 2013
As a common generalization of bipartite and split graphs, monopolar graphs are defined in terms of the existence of certain vertex partitions. It has been shown that to determine whether a graph has such a partition is an NP-complete problem for general ...

Stability and Phase Separation in Mixed Monopolar Lipid/Bolalipid Layers [PDF]

open access: yes, 2007
The phase stability of a fluid lipid layer that is a mixture of conventional monopolar lipids and C20 bipolar bolalipids was studied using a mean field theory that explicitly includes molecular details and configurational properties of the lipid ...

Monopolar and bipolar stimulation of the brain

open access: yes, 1962
Intracranial self-stimulation experiments in the dog using a two-wire electrode, with each wire used as a monopolar electrode and the combination as a bipolar electrode, show that monopolar stimulation may produce either a higher or a lower rate of ...

A review of monopolar motor mapping and a comprehensive guide to continuous dynamic motor mapping for resection of motor eloquent brain tumors.

open access: yes, 2017
Monopolar mapping of motor function differs from the most commonly used method of intraoperative mapping, i.e. bipolar direct electrical stimulation at 50-60Hz (Penfield technique mapping). Most importantly, the monopolar probe emits a radial, homogenous

How to halve ploidy : lessons from budding yeast meiosis [PDF]

open access: yes, 2012
Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

Monopolar pulsar spin-down

open access: yes, 2004
A multipole spin-down equation based on a monopolar term is derived from the general expression $\dot{\nu} = -f(\nu,t)$ and used to study pulsar evolution.

A Dual-Frequency Patch Antenna with Monopolar Radiation Pattern [PDF]

open access: yes, 2010
In this communication, a patch antenna with two monopolar modes is proposed. These monopolar modes can be excited by using one or two different coaxial ports.

Antena de Parche Monopolar de Doble Frecuencia [PDF]

open access: yes, 2010
A dual-frequency patch antenna with monopolar radiation patterns at both working frequencies is presented in this paper. The antenna design is based on a conventional patch with two concentric short-circuited conditions with a separating gap between ...

Monopolar and Bipolar Modalities of Transurethral Prostate Resection [PDF]

open access: yes, 2015
Benign prostate hyperplasia (BPH) related lower urinary tract symptoms (LUTS) is among the most common diseases in the aging male. Both medical and surgical treatment modalities have been improved strikingly in the last 20 years.
