Synthesis And Analysis Of An Α-Amylase Inhibitor And An Antimicrobial Peptide, Brahmlin Kaur Sethi

Senior Honors Theses and Projects

Abstract 1: α-Amylase is an important enzyme in the body responsible for hydrolyzing many polysaccharides such as dietary starch. Inhibition of this enzyme could be extremely beneficial in diabetic patients because it could lower the glucose levels in the blood. Our objective is to synthesize a small analog of a natural α-amylase inhibitor, Tendamistat. This molecule has 15-22 residue segment that are critical for its activity. The peptide was synthesized, cleaved, purified, analyzed, and an enzyme assay was run. Michaelis Menton and Lineweaver-Burk plots were constructed to determine the V_max, K_m, and K_i for each …

Gray whales Eschrichtius robustus exist as a 2 geographically and genetically distinct populations in the eastern and western North Pacific. Subjected to intensive commercial whaling during the 19th and 20th centuries, the western population presently numbers approximately 100 individuals and is regarded as one of the most endangered baleen whale populations in the world.

Spatial Statistical Models That Use Flow And Stream Distance, Jay M. Ver Hoef, Erin Peterson, David Theobald

United States Department of Commerce: Staff Publications

We develop spatial statistical models for stream networks that can estimate relationships between a response variable and other covariates, make predictions at unsampled locations, and predict an average or total for a stream or a stream segment. There have been very few attempts to develop valid spatial covariance models that incorporate flow, stream distance, or both. The application of typical spatial autocovariance functions based on Euclidean distance, such as the spherical covariance model, are not valid when using stream distance. In this paper we develop a large class of valid models that incorporate flow and stream distance by using spatial …

Cetacean Abundance In Hawaiian Waters Estimated From A Summer/Fall Survey In 2002, Jay Barlow

United States Department of Commerce: Staff Publications

Cetacean abundance is estimated for the U.S. Exclusive Economic Zone (EEZ) around the Hawaiian Islands based on a ship line-transect survey from August to November, 2002. Sighting detection functions are estimated from this and other NOAA research surveys from 1986 to 2002 using a new, multiple-covariate approach. Twenty-four species were seen on this survey, including two species (Fraser’s dolphin [Lagenodelphis hosei] and sei whale [Balaenoptera borealis]) that had not been previously documented to occur in Hawaiian waters. The most abundant large whales are sperm whales (Physeter macrocephalus) and Bryde’s whales (Balaenoptera edeni). The most …

Geochemical Data For Mercury, Methylmercury, And Other Constituents In Sediments From Englebright Lake, California, 2002, Charles N. Alpers, Michael P. Hunerlach, Mark C. Marvin-Dipasquale, Ronald C. Antweiler, Brenda K. Lasorsa, John F. De Wild, Noah P. Snyder

United States Geological Survey: Publications

This report presents geochemical data from two 2002 sampling campaigns conducted in Englebright Lake on the Yuba River in northern California. A deep coring campaign was done in May–June 2002 and a shallow sampling campaign was completed in October 2002. This work assessed the chemical composition of material deposited in the reservoir between 1940, the year Englebright Dam was completed, and 2002 as part of the Upper Yuba River Studies Program, an effort designed to evaluate the feasibility of introducing anadromous fish, including steelhead and spring-run Chinook salmon, upstream from Englebright Dam. Results of analyses of total mercury (HgT) in …

Adaptive Harvest Management: 2006 Hunting Season

United States Fish and Wildlife Service: Publications

The process of setting waterfowl hunting regulations is conducted annually in the United States (Blohm 1989). This process involves a number of meetings where the status of waterfowl is reviewed by the agencies responsible for setting hunting regulations. In addition, the U.S. Fish and Wildlife Service (USFWS) publishes proposed regulations in the Federal Register to allow public comment. This document is part of a series of reports intended to support development of harvest regulations for the 2006 hunting season. Specifically, this report is intended to provide waterfowl managers and the public with information about the use of adaptive harvest management …

American Woodcock Population Status, 2006, James R. Kelley Jr., Rebecca D. Rau

United States Fish and Wildlife Service: Publications

Singing-ground Survey data indicated that the numbers of displaying American woodcock (Scolopax minor) in the Eastern Region in 2006 was unchanged from 2005; however, the Central Region experienced an 8% decline. There was no significant trend in woodcock heard in either the Eastern or Central Region during 1996-06. This represents the third consecutive year since 1992 that the 10-year trend estimate did not indicate a significant decline. There were longterm (1968-06) declines of 1.9% per year in the Eastern Region and 1.8% per year in the Central Region. The 2005 recruitment index for the U.S. portion of the …

Evolution Of The Snow Area Index Of The Subarctic Snowpack In Central Alaska Over A Whole Season. Consequences For The Air To Snow Transfer Of Pollutants, A.S. Taillandier, F. Domine, W.R. Simpson, M. Sturm, T.A. Douglas, K Severin

United States Army: Publications

The detailed physical characteristics of the subarctic snowpack must be known to quantify the exchange of adsorbed pollutants between the atmosphere and the snow cover. For the first time, the combined evolutions of specific surface area (SSA), snow stratigraphy, temperature, and density were monitored throughout winter in central Alaska. We define the snow area index (SAI) as the vertically integrated surface area of snow crystals, and this variable is used to quantify pollutants’ adsorption. Intense metamorphism generated by strong temperature gradients formed a thick depth hoar layer with low SSA (90 cm² g^-1) and density (200 kg …

A Report On The Potential Use Of Usda Forest Service Forest Inventory And Analysis Data By The Bureau Of Land Management, Bill Williams, Tracey Frescino, Larry Deblander, Sharon Woudenberg, Michael J. Wilson

United States Bureau of Land Management: Staff Publications

The Bureau of Land Management (BLM) does not have a consistent internal program or source of vegetation data to use for strategic level planning, such as in resource management plans. This technical note discusses and evaluates the potential of the USDA Forest Service Forest Inventory and Analysis (FIA) Program to assist the BLM in filling this data gap. The FIA program is the Forest Service’s national program for collecting and reporting information on status and trends in forested ecosystems. The FIA is considered here because it is the only standard, nationwide, systematic assessment of forest land available. The technical note …

Aberration-Free Negative-Refractive-Index Lens, Jiajun Chen, Cosmin Radu, Ashok Puri

Physics Faculty Publications

The aberrations of a spherical lens composed of left-handed materials are studied in this letter. Five Seidel aberrations (spherical, coma, astigmatism, field curvature, and distortion) as a function of the refractive index n and shape factor q of the lens are considered. Our numerical calculations show that the negative refractive index gives much larger windows of small values of aberrations than the positive index, which will significantly enhance the flexibility for the design of an optical lens. Two possible regions with optimized aberrations are proposed: n = −1, q = −2.2 and n = −0.81 and q = 0.83

It illustrates the application of a network approach to empirical data by identifying the result of a network science study of patent acknowledgement.

The Constitution And Political Competition, Richard H. Pildes

Faculty Articles

Competitive elections are the minimal essential element of democratic systems. They promote broad public debate, stimulate voter participation, and are the central means by which voters hold officeholders accountable. Yet as is now widely recognized, such elections are in decline in the United States, due in part to the intentional and systematic creation of artificially safe election districts. This article provides a constitutional framework for responding to this problem. In recent years, the Supreme Court has more aggressively enforced constitutional limitations on the scope of Congress's enumerated powers. In the same way, the Court has begun to enforce limits on …

Enumerations Of The Kolmogorov Function, Richard Beigel, Harry Buhrman, Peter Fejer, Lance Fortnow, Piotr Grabowski, Luc Longpré, Andrej Muchnik, Frank Stephan, Leen Torenvliet

Computer Science Faculty Publication Series

A recursive enumerator for a function h is an algorithm f which enumerates for an input x finitely many elements including h(x). f is a k(n)-enumerator if for every input x of length n, h(x) is among the first k(n) elements enumerated by f. If there is a k(n)-enumerator for h then h is called k(n)-enumerable. We also consider enumerators which are only A-recursive for some oracle A.

We determine exactly how hard it is to enumerate the Kolmogorov function, which assigns to each string x its Kolmogorov complexity:

• For every underlying universal machine U, there is a constant a …

Evaluating Lookup-Based Monocular Human Pose Tracking On The Humaneva Test Data, Nicholas Howe

Computer Science: Faculty Publications

This work presents an evaluation of several lookup-based methods for recovering three-dimensional human pose from monocular video sequences. The methods themselves are largely described elsewhere [1, 2], although the work presented here incorporates a few minor enhancements. The primary contribution of this work is the evaluation of the results on a data set with ground truth available, which allows for quantitative comparisons with other techniques. Methods relying upon silhouettes produced via background subtraction tend to act as a “straw man” in relation to the current state of the art; many recently proposed techniques work without reliance upon background subtraction and …

Polygons Flip Finitely: Flaws And A Fix, Erik D. Demaine, Blaise Gassend, Joseph O’Rourke, Godfried T. Toussaint

Computer Science: Faculty Publications

Every simple planar polygon can undergo only a finite number of pocket flips before becoming convex. Since Erdős posed this as an open problem in 1935, several independent purported proofs have been published. However, we uncover a plethora of errors and gaps in these arguments, and remedy these problems with a new (correct) proof.

Concept Based Document Clustering Using A Simplicial Complex, A Hypergraph, Kevin Lind

Master's Projects

This thesis evaluates the effectiveness of using a combinatorial topology structure (a simplicial complex) for document clustering. It is believed that a simplicial complex better identifies the latent concept space defined by a collection of documents than the use of hypergraphs or human categorization. The complex is constructed using groups of co-occurring words (term associations) identified using traditional data mining methods. Disjoint subsections of the complex (connect components) represent general concepts within the documents’ concept space. Documents clustered to these connect components will produce meaningful groupings. Instead, the most specific concepts (maximal simplices) are used as representative connect components to …

Study Of Rna Secondary Structure Prediction Algorithms, Lisa Yu

Master's Projects

Dynamic programming algorithms such as Nussinov algorithm and Zuker algorithm define criteria to search the most stable RNA secondary structures. Stochastic Context-Free Grammar (SCFG) predicts the most possible RNA secondary structure using context-free grammar and a defined set of probabilities for each grammar rule. These algorithms form the base of using computer programs to predict RNA secondary structures without pseudoknots. In this report, we review these RNA secondary structure prediction algorithms and present our own software implementations of these algorithms. The Nussinov algorithm is easy to understand. But our results show that the Nussinov algorithm is overly simplified and can …

Compact Representation Of Association Rule, Mien K. Siao

Master's Projects

Bitmap is an extremely efficient way of representing data, but the drawback is that the order of data is fixed in a bitmap. Granular computing is a new theory that frees the bitmap method from fixed order of data in the same manner as linear algebra frees the matrix theory from a fixed basis. To obtain meaningful information using data mining techniques has been a central idea in recent database applications [2]. One of the core techniques in data mining is to find associations (undirected association rules) between attribute values [4]. The complexity of finding associations is often very high. …

Geometry-Based Detection Of Flash Worms, Sang Soo Kim

Master's Projects

While it takes traditional internet worms hours to infect all the vulnerable hosts on the Internet, a flash worm takes seconds. Because of the rapid rate with which flash worms spread, the existing worm defense mechanisms cannot respond fast enough to detect and stop the flash worm infections. In this project, we propose a geometric-based detection mechanism that can detect the spread of flash worms in a short period of time. We tested the mechanism on various simulated flash worm traffics consisting of more than 10,000 nodes. In addition to testing on flash worm traffics, we also tested the mechanism …

Juice: An Svg Rendering Peer For Java Swing, Ignatius Yuwono

Master's Projects

SVG—a W3C XML standard—is a relatively new language for describing low-level vector drawings. Due to its cross-platform capabilities and support for events, SVG may potentially be used in interactive GUIs/graphical front-ends. However, a complete and full-featured widget set for SVG does not exist at the time of this writing. I have researched and implemented a framework which retargets a complete and mature raster- based widget library—the JFC Swing GUI library—into a vector-based display substrate: SVG. My framework provides SVG with a full-featured widget set, as well as augmenting Swing’s platform coverage. Furthermore, by using bytecode instrumentation techniques, my Swing to …
