Photonic nanojets have been previously shown (both theoretically and experimentally) to be highly sensitive to the presence of an ultra-subwavelength nanoscale particle within the nanojet. In the present work, photonic nanojets elongated by almost an order of magnitude (relative to the latest previously published work) are found to possess another key(More)
Acknowledgments This article has benefited from the valuable suggestions of Jesus Almendros (Universidad de Almería) and the kind assistance of Pilar Vargas (Universidad de La Rioja) Abstract It seems clear that there is plenty of room for improvement in the area of IS client-developer working relationship. On the client side, it is general to find(More)
Biotechnological research on marine organisms, such as ex situ or in situ aquaculture and in vitro cell culture, is being conducted to produce bioactive metabolites for biomedical and industrial uses. The Caribbean marine sponge Discodermia dissoluta is the source of (+)-discodermolide, a potent antitumoural polyketide that has reached clinical trials. This(More)
─ It is currently believed that nanometer-scale internal refractive index fluctuations within biological cells change significantly during the initial stages of ultra early-stage cancer development well in advance of these changes becoming more pronounced and histologically detectable. Here, backscattered cepstral results of photonic nanojet-illuminated(More)
─ It is becoming increasingly important to computationally predict, study, and prevent electromagnetic compatibility (EMC) issues arising within and between ICs and other components comprising portable electronic devices. Here, we conduct a phenomenological study involving an ultra high-resolution, three-dimensional finite-difference time-domain (FDTD)(More)
Cinara cupressi (Buckton) is an important aphid pest of the Cupressaceae family, originally reported in Chile in 2003. Since then, it has spread over 4,000 km, contributing to conservation issues, mostly associated with native and urban trees of the Cupressaceae. In the present work, the morphometric variation of C. cupressi was examined to determine if the(More)
To understand the effects of global warming in tropical insect communities, it is necessary to comprehend how such communities respond to different abiotic factors that covariate with altitude. In this study, we partially answer this question applied to dung beetle communities distributed along an altitudinal gradient. The sampling was conducted in seven(More)
