2D Tracking the Nuptial Dance of Platynereis Dumerilii Worms

2D tracking of Platynereis dumerilii worms during spawning

Platynereis dumerilii are marine worms that reproduce by external fertilisation and exhibit particular swimming behaviours during spawning. In this paper we propose a novel worm tracking approach that enables the 2D tracking and feature extraction during the spawning process of these worms. The gathered data will be used in the future to characterise and compare male and female spawning behavio...

Genetic and Genomic Tools for the Marine Annelid Platynereis dumerilii

The bristle worm Platynereis dumerilii displays many interesting biological characteristics. These include its reproductive timing, which is synchronized to the moon phase, its regenerative capacity that is hormonally controlled, and a slow rate of evolution, which permits analyses of ancestral genes and cell types. As a marine annelid, Platynereis is also representative of the marine ecosystem...

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...
