The introduction of T parity dramatically improves the consistency of Little Higgs models with precision electroweak data, and renders the lightest T-odd particle (LTP) stable. In the Littlest Higgs model with T parity, the LTP is typically the T-odd heavy photon, which is weakly interacting and can play the role of dark matter. We analyze the relic abundance of the heavy photon, including its ...

We examine the dark matter phenomenology of a composite electroweak singlet state. This singlet belongs to the Goldstone sector of a well-motivated extension of the Littlest Higgs with T-parity. A viable parameter space, consistent with the observed dark matter relic abundance as well as with the various collider, electroweak precision and dark matter direct detection experimental constraints i...

The development of new strategies to enhance the healing of fractures continues to evolve with the introduction of both locally and systemically delivered compounds. The recent refinement in the use of autologous bone marrow as a bone graft material has brought the field of stem cell biology into orthopaedic practice. New recombinant peptides such as platelet- derived growth factor and teripara...

This article discusses two theorems of Georg Cantor: Cantor’s Little Theorem and Cantor’s Diagonal Theorem.These results are obtained by generalizing the method of proof ofthe well known Cantor’s theorem about the cardinalities of a setand its power set. As an application of these, Gödel’s firstincompleteness theorem is proved. Hints are given as to how to derive other deeper results including ...

Submitted January 10, 2015; revision received February 15, 2015; accepted February 24, 2015. “Little league shoulder” is caused by repeated overhead throwing in athletes between the ages of 11 and 14 years during peak proximal physis growth.1,2 The rotational torque during maximum external rotation when throwing overhead seems to be the primary cause of growth plate failure.1-3 (doi:10.7556/jao...

A Thoma, I Alexopoulou. Circumferential little finger nailplate. Can J Plast Surg 1995;3(3):161-162. This is a case report of a seven-year-old female who presented with a congenital anomaly of the little finger in which the nailplate was circumferentially covering the tip of the distal phalanx. There was a well-developed eponychial fold on the palmar aspect of the digit. This rare congenital `c...

18 P hotons come in many beautiful colors and are very useful for transmitting information with little loss over large distances. However, photons are also a little boring: they essentially do not interact with one another. This absence of interactions, or equivalently, the linearity of the optical response, is what allows one to send powerful optical pulses over large distances through optical...
