Directed self-assembly (DSA) is a type of directed assembly which utilizes block co-polymer morphology to create lines, space and hole patterns, facilitating for a more accurate control of the feature shapes. Then it uses surface interactions as well as polymer thermodynamics to finalize the formation of the final pattern shapes. [1]
Through DSA, students can secure a school placement before taking their Primary School Leaving Examination (PSLE) or Ordinary-Level (O-Level) examination. [2] However, the DSA-JC scheme was introduced later, in 2005, a year after DSA-Sec, allowing Secondary 4 (S4) and Secondary 5 (S5) students to apply for early admissions to junior colleges.
In the process, the 142nd leadership became the Subject Matter Expert (SME) in the most effective placement and utilization of Electronic Counter-Measures (ECM). The 142nd also provided battalion-level command and control of both the internal and external Military Transition Teams (MiTTs) for the Iraqi Army (IA) 3s Division's Motorized ...
Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a ...
The DSA was established in Ba Htoo Station in southern Shan State on 1 August 1954, and was moved to its current home, a former British hill station of Pyin Oo Lwin (formerly, Maymyo) between 20 and 26 June 1957. [4]
Maximum volume submatrix – Problem of selecting the best conditioned subset of a larger matrix. This class of problem is associated with Rank revealing QR factorizations and D optimal experimental design. [39] Minimal addition chains for sequences. [40]
On March 29, 2011, two researchers published an IACR paper [9] demonstrating that it is possible to retrieve a TLS private key of a server using OpenSSL that authenticates with Elliptic Curves DSA over a binary field via a timing attack. [10] The vulnerability was fixed in OpenSSL 1.0.0e. [11]
Mixed metal oxide (MMO) electrodes, also called Dimensionally Stable Anodes (DSA), are devices with high conductivity and corrosion resistance for use as anodes in electrolysis. They are made by coating a substrate, such as pure titanium plate or expanded mesh, with several kinds of metal oxides.
