A model is described which explains drag reduction (DR) in dilute polymer solutions in terms of solvation of macromolecular chains and formation of relatively stable domains. The domains partly suppress the vortex formation, act as energy sinks, and also play a role in mechanical degradation in flow (MDF). We report ultrasonically determined solvation numbers for a series of copolymers with the...

Recent research has demonstrated the superiority of SVM-based approaches for offline cursive character recognition. In particular, Camastra’s 2007 study showed SVM to be better than alternative LVQ and MLP approaches on the large C-Cube data set. Subsequent work has applied hierarchical vector quantization (HVQ) with temporal pooling to the same data set, improving on LVQ and MLP but still not ...

This paper describes a new technique for extracting patterns and relations visually from multidimensional binary data using monotone Boolean functions. Visual Data Mining (VDM) has shown benefits in many areas when used with numerical data, but that technique is less beneficial for binary data. This problem is especially challenging in medical applications tracked with binary symptoms. The prop...

this study was aimed to investigate the bending moment and stress (inner and outer corners) in lshaped biscuit joint made of solid wood, particleboard and medium density fiberboard (mdf). for this purpose, l-shaped joints made of beech and fir, particleboard and mdf by biscuit size numbers of 0 (47×15×3.8 mm), 10 (53×19×3.8mm) and 20 (60×23×3.8mm). bending moment and stress carrying capacity of...

As lecturers in pathology it is our task to impart a smattering of pathological knowledge to the modern Bristol medical student. In doing so we are forced to utilise the age old descriptive terms of surgical pathology passed down to us from time when Virchow was an SHO! Far from making our task easy, we are often asked to explain in terms more appropriate to the twentieth century what these arc...

THE TITLE SYDNONE DERIVATIVE [SYSTEMATIC NAME: 2-bromo-1-(5-oxido-3-phenyl-1,2,3-oxadiazo-lium-4-yl)-3-phenyl-prop-2-en-1-one], C(17)H(11)BrN(2)O(3), exists in a Z configuration with respect to the acyclic C=C bond. An intra-molecular C-H⋯Br hydrogen bond generates a six-membered ring, producing an S(6) ring motif. The 1,2,3-oxadiazole ring in the sydnone unit is essentially planar [maximum dev...

The generation of mice lacking SCYL1 or SCYL2 and the identification of Scyl1 as the causative gene in the motor neuron disease mouse model muscle deficient (Scyl1(mdf/mdf) ) demonstrated the importance of the SCY1-like family of protein pseudokinases in neuronal function and survival. Several essential cellular processes such as intracellular trafficking and nuclear tRNA export are thought to ...

This paper is about an efficient implementation of adaptive filtering for echo cancelers. The first objective of this paper is to propose a simplified method of the flexible block Multi-Delay Filter (MDF) algorithm in the time-domain. Then, we will derive a new method for the stepsize adaptation coefficient. The second objective is about the realization of a Block Proportionate Normalized Least...

Fanconi anemia (FA) is known as an inherited bone marrow failure syndrome associated with cancer predisposition and susceptibility to a number of DNA damaging stimuli, along with a number of clinical features such as upper limb malformations, increased diabetes incidence and typical anomalies in skin pigmentation. The proteins encoded by FA-defective genes (FANC proteins) display well-establish...
