Abstract. In this paper we study the shape of least-energy solutions to the quasilinear problem ε∆mu−u + f (u) = 0 with homogeneous Neumann boundary condition. We use an intrinsic variation method to show that as ε → 0, the global maximum point Pε of least-energy solutions goes to a point on the boundary ∂Ω at the rate of o(ε) and this point on the boundary approaches to a point where the mean ...

Descents, Peaks, and P -partitions A dissertation presented to the Faculty of the Graduate School of Arts and Sciences of Brandeis University, Waltham, Massachusetts by T. Kyle Petersen We use a variation on Richard Stanley’s P -partitions to study “Eulerian” descent subalgebras of the group algebra of the symmetric group and of the hyperoctahedral group. In each case we give explicit structure...

Since the published MS-GFDB did not support variable PTMs at the time that this research was carried out, both MS-GFDB and PEAKS DB were run without specifying any variable PTMs. The other parameters, including the fixed PTMs, remained the same as described in the results section. The results are shown in Figure S2 for CID and Figure S3 for ETD datasets, respectively. Note that the removal of t...

An image may be decomposed as a difference between an image of peaks and an image of wells. Applying a morphological operator to these two components before reconstructing a final image produces interesting filters for grey tone or binary images. This decomposition depends upon the point of view from where the image is considered.

The aim of this paper is to develop a rapid, and highly sensitive quantitative HPLC fingerprint method with multiple indicators by using the Compound Chinese Medicine Wuwei Changyanning granule and 5 herbs in the prescription. The quantitative fingerprint chromatogram with multiple indicators was investigated. ⅰ)6 compositions included rutin, gallic acid, chlorogenic acid, atractylenolideⅠ, pac...

Vibration Analysis Tests (VAT) and Acoustic Emission tests (AE) are used in several industrial applications. Many of them perform analysis in the frequency domain. Peaks in the power density spectrum hold relevant information about acoustic events. In this paper we propose a novel method for feature extraction of vibration samples by analyzing the shape of their auto power spectrum density func...

The usefulness of Fourier analyses as a tool for determining key parameters of cancellous bone structure is investigated. The autocorrelation function is used to determine measures of preferred orientation of trabeculae and anisotropy. Peaks in the power spectrum are used to determine average trabecular strut spacing. Good agreement and high correlations were observed when these frequency domai...

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...

This paper presents vascular tree reconstruction and artery-vein separation methods from 3D thoracic CT-angiography (CTA) images. In the methods, the lungs, blood vessels and the heart are segmented by using intensity-based thresholds and morphological operations. After the distance transform for the regions of blood vessels and the heart, we compute seed points that are the maxima of distance ...
