Impacts from a changing climate, in particular sea-level rise, will be most acutely felt on small oceanic islands. A common configuration of mid-latitude islands is the sandy barrier island. Sable Island, Nova Scotia, Canada vegetated sand island near shelf edge, 160 km nearest point land, that morphologically similar to This study uses 60 years airphoto records analyse changes coastline positi...

Island ecosystems are particularly vulnerable to exotic species. Here we show how an introduced prey has led to the wholesale restructuring of an island food web, including the near extinction of an endemic carnivore. Introduced pigs, by providing abundant food, enabled golden eagles to colonize the California Channel Islands. Eagles preyed heavily on the island fox, whose resulting decline tow...

fungal pathogens could be isolated from sputum by classic and molecular methods. After 4–5 days, his temperature was 40°C, a productive cough with dyspnea was noted, and his condition deteriorated. A chest radiograph showed progression of the infiltrates, and a computed tomography scan of the abdomen and chest showed infiltrates near the pleura, suggesting encapsulated fluid (Figure). An ultras...

A low-energy electron microscopy study of two-dimensional Si~001! island shapes near thermal equilibrium on 10315 mm large single-domain terraces reveals a continuous increase of island aspect ratio and a shape transition from elliptical to ‘‘American-football’’-like with increasing island size. The size-dependent island shapes are driven by elastic relaxation caused by the intrinsic surface st...

Multi-fold cross-validation is an established practice to estimate the error rate of a learning algorithm. Quantifying the variance reduction gains due to cross-validation has been challenging due to the inherent correlations introduced by the folds. In this work we introduce a new and weak measure called loss stability and relate the cross-validation performance to this measure; we also establ...

Empirical Green Functions (EGFs) obtained from ambient noise cross-correlation are important for imaging and monitoring underground structures. The EGFs on the Island of Hawai'i in different years similar at low frequencies (0.1–0.4 Hz), but very high (0.4–1.0 Hz): Only after 2018 Kı̄lauea eruption show clear P waves. Grid search reveals a strong source near summit before eruption, which contami...

the urban heat island effect refers to the temperature rise of the cities in comparison to the suburbs. this phenomenon which is a consequence of urbanization and has become a major issue in the urban climatology may have serious consequences in the developing countries which are facing a rapid and unplanned urban growth. tehran, the capital and the most populated city of iran, this phenomenon ...
