An anonymous self-administered online questionnaire was distributed among non-ophthalmic physicians-in-training at the Philippine General Hospital (PGH) using convenience and snowball sampling.Results: A total of 77 responses were recorded with a response rate of 37%. The majority of the respondents uniformly reported the absence of an established eye care protocol or policy being implemented for different subsets of patients at risk for developing exposure keratopathy. Ninety-six percent (96%) was aware of exposure keratopathy. The most urgent reason for referral to the ophthalmology service was the presence of whitish of opacity at 46.8%, while the least urgent reason was the presence of eye redness at 36.4%. Only 43% of the patients with incomplete eyelid closure was referred to the ophthalmology service. The most frequently used modality of prophylactic eye protection treatment was eyelid taping (84.4%) followed by lubricants (drops and gels, 79.1%). The most common reason for not referring was the absence of an established protocol on the appropriate indication for referral to the ophthalmology service.Conclusion: This study showed that the majority of non-ophthalmic physicians-in-training had adequate knowledge and favorable attitude regarding recognition and prevention of ex

Historical records and genetic analyses indicate that Latin Americans trace their ancestry mainly to the intermixing (admixture) of Native Americans, Europeans and Sub-Saharan Africans. Using novel haplotype-based methods, here we infer sub-continental ancestry in over 6,500 Latin Americans and evaluate the impact of regional ancestry variation on physical appearance. We find that Native American ancestry components in Latin Americans correspond geographically to the present-day genetic structure of Native groups, and that sources of non-Native ancestry, and admixture timings, match documented migratory flows. We also detect South/East Mediterranean ancestry across Latin America, probably stemming mostly from the clandestine colonial migration of Christian converts of non-European origin (Conversos). Furthermore, we find that ancestry related to highland (Central Andean) versus lowland (Mapuche) Natives is associated with variation in facial features, particularly nose morphology, and detect significant differences in allele frequencies between these groups at loci previously associated with nose morphology in this sample.

We effectively sew two vertices with ghosts in order to obtain a third, composite vertex in the most general case of cycling transformations. In order to do this, we separate the vertices into two parts: a bosonic oscillator part and a ghost oscillator part and write them as canonical forms., Comment: 13 pages

The measure for the one loop scattering of one and $N$ bosonic strings is calculated using the Group Theoretic approach to String Theory. The calculation is done for the case when the projective transformation associated with the loop can be parametrized in terms of two finite fixed points and the multiplier., Comment: LaTeX2e, 11 pages

It is shown how to sew string vertices with ghosts at tree level in order to produce new tree vertices using the Group Theoretic approach to String Theory. It is then verified the BRST invariance of the sewn vertex and shown that it has the correct ghost number., Comment: LaTeX, 26 pages, 19 figures

In this article, it is shown how to obtain objects called Eichler integrals in the mathematical literature that can be used for calculating scattering amplitudes in String Theory. These Eichler integrals are also new examples of Eichler integrals with poles., Comment: LaTeX, 16 pages
