Widely distributed breeding populations of Canada warbler (Cardellina canadensis) converge on migration through Central America

Background To effectively conserve migratory species, the entire range encompassed by their annual life cycle needs to be considered. Most research on Nearctic-Neotropical migratory birds has focused on the breeding grounds resulting in a general lack of knowledge regarding the wintering and migratory periods. The Canada Warbler (Cardellina canadensis) has declined by 71% from 1970 to 2012, at a rate of 2.9% per year, and is listed as Threatened in Canada. As with most Nearctic-Neotropical migrants, conservation efforts outside the breeding range are limited by a poor understanding of migration routes and the connectivity between specific breeding and wintering populations. Results To determine migratory routes of multiple breeding populations of Canada Warblers, we directly-tracked individuals using light-level geolocators deployed at four sites across the breeding range, spanning approximately 43 degrees in longitude (Alberta, Manitoba and Québec, Canada, and New Hampshire, USA). Twenty-five geolocators with usable data were recovered from three sites and were analyzed using FlightR to determine fall migration routes (n = 18) and individual wintering sites (n = 25). Individuals from all breeding populations took a western fall migration route at the Gulf of Mexico; with 77.8% of birds funnelling into a narrow geographic space along the western side of the Gulf of Mexico (97°W-99°W). We found no evidence for population-specific, parallel migration routes. Most individuals (72%) overwintered in Colombia. The remaining individuals overwintered in Venezuela. Conclusions Our results demonstrate convergence of migratory routes around a migration barrier for individuals originating from widely distributed breeding areas. Further, we suggest the potential importance of habitat around the Gulf of Mexico during migration and Andean forest in Colombia as overwintering habitat for this threatened species. Future research should be directed at understanding how these areas are used by Canada Warblers

Low-Energy Theorems from Holography

In the context of gauge/gravity duality, we verify two types of gauge theory low-energy theorems, the dilation Ward identities and the decoupling of heavy flavor. First, we provide an analytic proof of non-trivial dilation Ward identities for a theory holographically dual to a background with gluon condensate (the self-dual Liu--Tseytlin background). In this way an important class of low-energy theorems for correlators of different operators with the trace of the energy-momentum tensor is established, which so far has been studied in field theory only. Another low-energy relationship, the so-called decoupling theorem, is numerically shown to hold universally in three holographic models involving both the quark and the gluon condensate. We show this by comparing the ratio of the quark and gluon condensates in three different examples of gravity backgrounds with non-trivial dilaton flow. As a by-product of our study, we also obtain gauge field condensate contributions to meson transport coefficients.Comment: 32 pages, 4 figures, two references added, typos remove

Оптимизация антибактериальной терапии у пациентов с эндо-пародонтальными поражениями

To improve the quality and effectiveness of medical care for patients with inflammatory periodontal diseases, it is necessary to search for new approaches in both diagnosis and treatment. The aim of our study is to determine the effect of the diode laser on the pathogenic microflora of periodontal pockets and root canals in patients with endo-periodontal lesions (EPL). We carried out a comparative assessment of the bacterial contents of the root canals and periodontal pockets by polymerase chain reaction (PCR) before and after treatment with a diode laser (Doctor Smile Simpler, wavelength 980 nm) for 54 patients with EPL. The control group consisted of 56 patients who were treated according to the generally accepted method, including professional oral hygiene, endodontic treatment, and curettage of periodontal pockets. Evaluation criteria were a qualitative assessment of the content of periodontopathogens in the root canal and periodontal pocket before and after and treatment. As a result of our study, we found a statistically significant (p<0.01) reduction in the colonization of periodontal pockets and root canals in patients with EPL after laser decontamination. The high technological effectiveness of the methods used in combination with the low risk of complications at the stages of endodontic and periodontological treatment provides an antibacterial effect and reduces the duration of inflammation. The results of treatment of patients using a diode laser give reason to recommend their use in the dental practice.Для повышения качества и эффективности оказания медицинской помощи пациентам с воспалительными заболеваниями пародонта необходим поиск новых подходов к диагностике и лечению патологии. Целью исследования было изучить влияние излучения диодного лазера на патогенную микрофлору пародонтальных карманов (ПК) и корневых каналов (КК) у пациентов с эндо-пародонтальными поражениями (ЭПП). Проведена сравнительная оценка бактериального содержимого КК и ПК методом полимеразно-цепной реакции (ПЦР) до и после лечения с применением стоматологического диодного лазера (Doctor Smile Simpler, длина волны 980 нм) у 54 пациентов с ЭПП. Группу контроля составили 56 пациентов, которым проводилось лечение по общепринятой методике, включающей профессиональную гигиену рта, эндодонтическое лечение и кюретаж ПК. Критерием оценки явилось качественное содержание пародонтопатогенов в КК и ПК до и после лечения. Выявлено статистически значимое (p<0,01) снижение обсемененности ПК и КК у пациентов с ЭПП после лазерной деконтаминации. Высокая технологичность использованных методик в сочетании с низкими рисками осложнений на этапах эндодонтического и пародонтологического лечения обеспечивает антибактериальный эффект и сокращает продолжительность воспалительных явлений. Результаты лечения пациентов с применением диодного лазера дают основание рекомендовать их использование в практике врача-стоматолога

Doping the holographic Mott insulator

Mott insulators form because of strong electron repulsions, being at the heart of strongly correlated electron physics. Conventionally these are understood as classical "traffic jams" of electrons described by a short-ranged entangled product ground state. Exploiting the holographic duality, which maps the physics of densely entangled matter onto gravitational black hole physics, we show how Mott-insulators can be constructed departing from entangled non-Fermi liquid metallic states, such as the strange metals found in cuprate superconductors. These "entangled Mott insulators" have traits in common with the "classical" Mott insulators, such as the formation of Mott gap in the optical conductivity, super-exchange-like interactions, and form "stripes" when doped. They also exhibit new properties: the ordering wave vectors are detached from the number of electrons in the unit cell, and the DC resistivity diverges algebraically instead of exponentially as function of temperature. These results may shed light on the mysterious ordering phenomena observed in underdoped cuprates.Comment: 27 pages, 9 figures. Accepted in Nature Physic
