In elution chromatography, mod$ers sometimes are added to the mobile phase to compete with sample solutes for binding sites in order to reduce the retention time and band spreading of sample solutes. In this work, the interrelationship between modiJiers and sample solutes in preparative and large-scale chromatography is investigated using a nonlinear multicomponent rate model in which axial dis...

We tackle the problem of simultaneously detecting occlusions and estimating optical flow. We show that, under standard assumptions of Lambertian reflection and static illumination, the task can be posed as a convex minimization problem. Therefore, the solution, computed using efficient algorithms, is guaranteed to be globally optimal, for any number of independently moving objects, and any numb...

Existing network benchmark tools suffer from problems such as portability, poor repeatability and inability to perform accurate testing of high-throughput networks. We have built a distributed benchmarking tool which solves many of these problems. ipbench provides an extensible distribution framework and makes minimal demands of the device under test. We have fully implemented a latency test wi...

Highly multimodal function optimization is similar to many other optimization problems requiring many iterations and large number of function evaluations. Glowworm Swarm Optimization (GSO) is one of the common swarm intelligence algorithms, where GSO has the ability to optimize multimodal functions efficiently. Locating the peaks of a high-dimensional multimodal function requires a large popula...

MOTIVATION The combination of liquid chromatography and mass spectrometry (LC/MS) has been widely used for large-scale comparative studies in systems biology, including proteomics, glycomics and metabolomics. In almost all experimental design, it is necessary to compare chromatograms across biological or technical replicates and across sample groups. Central to this is the peak alignment step, ...

The conventional parboiling of rough rice is a lengthy process that takes 24-28 h to complete. It would be beneficial to the industry if the processing time could be reduced. The objective of this study was to develop an ultrasound based one-step protocol for soaking and gelatinization during rice parboiling. The gelatinization temperature was measured by alkali (KOH) degradation and found to b...

JUST over one hundred years ago Robert Graves, in an address to medical students, wrote these words: "Be assured of this, that however accurate be your knowledge of anatomy, however skilful you may be in chemical theories and manipulations, however extensively you may have mastered botany, however well you are acquainted with the nature and properties of drugs-be assured, I say, that you have a...

In this paper, we focus on a “local property” of permutations: value-peak. A permutation σ has a value-peak σ(i) if σ(i − 1) < σ(i) > σ(i + 1) for some i ∈ [2, n − 1]. Define V P (σ) as the set of value-peaks of the permutation σ. For any S ⊆ [3, n], define V Pn(S) such that V P (σ) = S. Let Pn = {S | V Pn(S) 6= ∅}. we make the set Pn into a poset Pn by defining S T if S ⊆ T as sets. We prove t...
