Pristomyrmex tsujii sp. n., an endemic species of the Fiji islands, is described from the worker, ergatoid queen, alate queen and male castes. The alate queen and male castes of Pristomyrmex mandibularis Mann are also described for the first time. The ergatoid queens for both species appear to be morphologically intermediate between the worker and alate queen castes. Pristomyrmex tsujii is read...

Mast cells are particularly in association with structures, especially the skin, respiratory, and digestive systems proximity to surfaces that interface external environment. This study was carry out demonstrate distribution heterogeneity of mast Angora goat glandula mandibularis by using morphological, histochemical, immunohistochemical methods. A total seven healthy male adult goats' mandibul...

Studies on tooth crown size and structure in families and in individuals with various sex chromosome anomalies have demonstrated differential direct effects of the human X and Y chromosome genes on growth. The Y chromosome promotes both tooth crown enamel and dentin growth, whereas the effect of the X chromosome on crown growth seems to be restricted to enamel formation. Enamel growth is decisi...

The mammalian jaw is often modelled as a third-class lever for the purposes of biomechanical analyses, owing to the position of the resultant muscle force between the jaw joint and the teeth. However, it has been proposed that in some rodents the jaws operate as a second-class lever during distal molar bites, owing to the rostral position of the masticatory musculature. In particular, the infra...

Coaxial Helicity Injection (CHI) experiments in the Helicity Injected Spherical Torus (HIST) device have produced discharges with peak plasma currents up to 150 kA and successfully sustained the plasma current for much longer than a resistive decay time. The flow measurements using a Mach probe have shown that the intermittent generation of the flow is correlated to the fluctuation seen on the ...

While peripheral sensory neurons respond to natural stimuli with a broad range of spatiotemporal frequencies, central neurons instead respond sparsely to specific features in general. The nonlinear transformations leading to this emergent selectivity are not well understood. Here we characterized how the neural representation of stimuli changes across successive brain areas, using the electrose...

The concept of a flowing lithium first wall for a fusion reactor may lead to a significant advance in reactor design, since it could virtually eliminate the concerns with power density and erosion, tritium retention, and cooling associated with solid walls. Sputtering and erosion tests are currently underway in the PISCES device at the University of California at San Diego (UCSD). To complement...

Objective Determine the effects of hyoid myotomy and suspension (HMS) without concurrent palatal or tongue base sleep surgery for obstructive sleep apnea (OSA). Method Patients with OSA treated with HMS were identified using CPT code (21685) at an academic and private sleep surgery clinic. Those who underwent concurrent palatal or tongue base sleep surgery were excluded. Outcomes included sim...

In this paper, we present a novel algorithm for watermarking a grayscale digital image with a binary watermark in the DCT domain. The algorithm is transparent since the watermark is not really embedded in the host image. This results in zero distortion of the watermarked host image. The embedded watermark is robust to most common unintentional attacks by intelligently utilizing the signs of the...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-200136 DESCRIPTION A 54-year-old man presented with vesicular rash and burning pain on the left mandibule. Two days before, the patient had developed pruritus in the same region. Clinical examination revealed vesicles on an erythematous base on the left lo...
