I suspect that scientific publications originated primarily as a means for disseminating research results. Today we live in a bigger and more complex, and perhaps also more number-dominated world, and publications serve also the goal of ranking researchers according to productivity, impact or other metrics [1, 2]. We also live in a highly-connected world, via the internet and the web. I believe...

This paper draws a parallel between document preparation and the traditional processes of compilation and link editing for computer programs. A block-based document model is described which allows for separate compilation of various portions of a document.These portions are brought together and merged by a linker program, called dlink, whose pilot implementation is based on ditroff and on its u...

The use of executable assertions is widely recognised as a useful programming technique for complex systems. In many cases static analysis of programs allows such assertions to be removed at compile time, thus removing the overhead of the test. The use of interprocedural analysis would often allow a larger number of such tests to be statically removed; intermodular analysis could even improve o...

S ister chromatids are often reluctant to separate during mitosis. Germann et al. show that a protein involved in DNA replication and repair helps eliminate lingering connections that can hold sister chromatids together (1). Sister chromatids tangle almost every time a cell enters mitosis. Unless the cell releases these links, the structures can break or fail to separate properly. Two kinds of ...

This article analyzes whether the technical characteristics of the Internet should create a separate legal jurisdiction, and if a separate jurisdiction would be beneficial to the Internet. Jurisdiction is a legal term for the limitation on the ability of a court to determine disputes. Generally, a nation state's jurisdiction only extends to individuals who reside within the country or to the tr...

مادة آلی محلول رنگی (CDOM) مقیاس مهمی در سنجش کیفیت آب است. می‌توان اذعان کرد CDOM نور موجود لایه‌های را کاهش می‌دهد و فعالیت‌های بیولوژیکی فتوسنتز مختل می‌کند سرانجام، مانع رشد جمعیت فیتوپلانکتون‌‌هایی می‌شود که برای زنجیرة غذای آبزیان ضروری‌اند. بیشتر تحقیق‌هایی تا کنون به انجام رسیده، از طول موج خاصی اندازه‌گیری ضریب جذب استفاده شده است اما، این تحقیق، امکان گسترة‌ وسیعی باندهای طیف مرئی، تع...
