Insects by the Million

One million insects--a lot of parasites?

Sound strategies: the 65-million-year-old battle between bats and insects.

The intimate details regarding the coevolution of bats and moths have been elucidated over the past 50 years. The bat-moth story began with the evolution of bat sonar, an exquisite ultrasonic system for tracking prey through the night sky. Moths countered with ears tuned to the high frequencies of bat echolocation and with evasive action through directed turns, loops, spirals, drops, and power ...

Non-sexual abdominal appendages in adult insects challenge a 300 million year old bauplan

pterygotes (e.g., the tracheobranchial appendages in mayfly nymphs, the tracheal gills of larval gyrinid beetles and those of neuropterids such as Corydalis) usually serve functions other than sexual, i.e., they are either respiratory or locomotory. As a first step to elucidate what drove the evolution of non-sexual abdominal appendages in Bennini, we investigated topology and anatomy of the ap...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
