Evo–Devo: Universal Toll Pass for the Extension Highway?
The distinction between long-germ and short-germ insects is a classic one in evo-devo, yet a common genetic mechanism may underlie germband extension in all insects, even all arthropods.
متن کاملImproved Artificial Low-pass Extension of Telephone Speech
In this contribution a new method for artificial bandwidth extension of telephone speech towards frequencies below 300 Hz is proposed. The method defines a self-contained module which can be applied to any artificial bandwidth extension system, designed for extending the bandwidth only to frequencies above the telephone-band. At this, the amplification of a separate ARMA filter with a pass-band...
متن کاملBy Pass Surgery
The bottom line is this: when patients are advised to have a coronary angiogram, chances are eight out of ten that they do not need it. The critical factor in whether a pa‐ tient needs coronary artery by‐ pass surgery or angioplasty is how well the left ventricular pump is working, not the de‐ gree of blockage or the number of arteries affected. The left ventricle (chamber) of the heart is resp...
متن کاملcontrol 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...
15 صفحه اولIterative separation of blended marine data: discussion on the coherence-pass filter
In conventional marine acquisition surveys the time intervals between the firing of successive sources are large enough to avoid interference in time. To obtain an efficient survey, the spatial source sampling is therefore often (too) large. However, much attention has been drawn recently to blended acquisition designs, where sources are shot in an overlapping fashion. Waiving the constraint of...
