A Comprehensive Program Description And Recommendations For The Del Rosa Youth Program, Martin C. Hodnett

Loma Linda University Electronic Theses, Dissertations & Projects

Amid budget cuts, economic recession, and difficulties many Americans face, more families are looking for ways to access needed services and goods from nongovernmental sources. Churches and faith based organizations, such as the Del Rosa Seventh-day Adventist (SDA) Church, have been bridging the gap for families seeking assistance, particularly in the area of youth services. The Del Rosa Youth Program, an outreach program sponsored by Del Rosa SDA Church, provides mentoring and religious programming for at-risk youth. In an effort to assist them in becoming more competitive for funding, the current project has reviewed the relevant literature and provided recommendations …

Supervised Manifold Distance Segmentation, Guany Wang

Computer Science ETDs

In this paper, I will propose a simple and robust method for image and volume data segmentation based on manifold distance metrics. In this approach, pixels in an image are not considered as points with color values arranged in a grid. In this way, a new data set is built by a transform function from one traditional 2D image or 3D volume to a manifold in higher dimension feature space. Multiple possible feature spaces like position, gradient and probabilistic measures are studied and experimented. Graph algorithm and probabilistic classification are involved. Both time and space complexity of this algorithm is …

Higher Order Difference Schemes For Heat Equation, Jianzhong Wang

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we construct the explicit difference schemes for the heat equation with arbitrary high orders. We also show the validity of the new schemes by numerical simulations.

A Generalized Newton-Penalty Algorithm For Large Scale Ill-Conditioned Quadratic Problems, Maziar Salahi, Moslem Ganji

Applications and Applied Mathematics: An International Journal (AAM)

Large scale quadratic problems arise in many real world applications. It is quite often that the coefficient matrices in these problems are ill-conditioned. Thus, if the problem data are available even with small error, then solving them using classical algorithms might result to meaningless solutions. In this short paper, we propose an efficient generalized Newton-penalty algorithm for solving these problems. Our computational results show that our new simple algorithm is much faster and better than the approach of Rojas et al. (2000), which requires parameter tuning for different problems.

Explicit And Exact Solutions With Multiple Arbitrary Analytic Functions Of Jimbo–Miwa Equation, Sheng Zhang, Ying-Na Sun, Jin-Mei Ba, Ling Dong

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, a generalized F-expansion method is used to construct exact solutions of the (3+1)-dimensional Jimbo–Miwa equation. As a result, many new and more general exact solutions are obtained including single and combined non-degenerate Jacobi elliptic function solutions, hyperbolic function solutions and trigonometric function solutions, each of which contains six arbitrary analytic functions. It is shown that with the aid of symbolic computation the generalized F-expansion method may provide a straightforward and effective mathematical tool for solving nonlinear partial differential equations.

Some Applications Of The (G'/G)-Expansion Method For Solving The Nonlinear Partial Differential Equations In Mathematical Physics, Nasir Taghizade, Ahmad Neirameh

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we construct the traveling wave solutions involving parameters of the combined Kdv-MKdv equation, the Shorma-Tasso-Olver equation and (2+1)-dimensional Konopelchenko-Dubrovsky equation, by using a new approach method. When the parameters are taken special values, the solitary waves are derived from the traveling waves. The travelling wave solutions are expressed by the hyperbolic functions, the trigonometric functions and the rational functions.

Pulsatile Flow Of Blood In A Constricted Artery With Body Acceleration, Devajyoti Biswas, Uday Shankar Chakraborty

Applications and Applied Mathematics: An International Journal (AAM)

Pulsatile flow of blood through a uniform artery in the presence of a mild stenosis has been investigated in this paper. Blood has been represented by a Newtonian fluid. This model has been used to study the influence of body acceleration and a velocity slip at wall, in blood flow through stenosed arteries. By employing a perturbation analysis, analytic expressions for the velocity profile, flow rate, wall shear stress and effective viscosity, are derived. The variations of flow variables with different parameters are shown diagrammatically and discussed. It is noticed that velocity and flow rate increase but effective viscosity decreases, …

Optimal Filtering Of An Advertising Production System With Deteriorating Items, Lakhdar Aggoun, Ali Benmerzouga, Lotfi Tadj

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we consider an integrated stochastic advertising-production system in the case of a duopoly. Two firms spend certain amounts to advertise some product. The expenses processes evolve according to the jumps of two homogeneous, finite-state Markov chains. We assume that the items in stock may be subject to deterioration and the deterioration parameter is assumed to be random.

Remarks On The Stability Of Some Size-Structured Population Models Vi: The Case When The Death Rate Depends On Juveniles Only And The Growth Rate Depends On Size Only And The Case When Both Rates Depend On Size Only, M. El-Doma

Applications and Applied Mathematics: An International Journal (AAM)

We continue our study of size-structured population dynamics models when the population is divided into adults and juveniles, started in El-Doma (to appear 1) and continued in El-Doma (to appear 2). We concentrate our efforts in two special cases, the first is when the death rate depends on juveniles only and the growth rate depends on size only, and, the second is when both the death rate and the growth rate depend on size only. In both special cases we assume that the maximum size for an individual in the population is infinite. We identify three demographic parameters and show …

Sphingosine-1-Phosphate Elicits Receptor-Dependent Calcium Signaling In Retinal Amacrine Cells, Scott Crousillac, Jeremy Colonna, Emily Mcmains, Jill Sayes Dewey, Evanna Gleason

Faculty Publications

Evidence is emerging indicating that sphingosine-1-phosphate (S1P) participates in signaling in the retina. To determine whether S1P might be involved in signaling in the inner retina specifically, we examine the effects of this sphingolipid on cultured retinal amacrine cells. Whole cell voltage-clamp recordings reveal that S1P activates a cation current that is dependent on signaling through Gi and phospholipase C. These observations are consistent with the involvement of members of the S1P receptor family of G-protein-coupled receptors in the production of the current. Immunocytochemistry and PCR amplification provide evidence for the expression of S1P1R and S1P3R in amacrine cells. The …

Water Stress Impacts On Bacterial Carbon Monoxide Oxidation On Recent Volcanic Deposits, Carolyn F. Weber, Gary M. King

Faculty Publications

Water availability oscillates dramatically on young volcanic deposits, and may control the distribution and activity of microbes during early stages of biological succession. Carbon monoxide (CO)-oxidizing bacteria are among the pioneering colonists on volcanic deposits and are subjected to these water stresses. We report here the effects of water potential on CO-oxidizing bacteria in unvegetated (bare) and vegetated (canopy) sites on a 1959 volcanic deposit on Kilauea Volcano (Hawai'i). Time course measurements of water potential showed that average water potentials in the surface layer (0-1 cm) of canopy soil remained between 0.1 and 0 MPa, whereas dramatic diurnal oscillations (for …

The Amino Terminus Of Herpes Simplex Virus Type 1 Glycoprotein K (Gk) Modulates Gb-Mediated Virus-Induced Cell Fusion And Virion Egress, Vladimir N. Chouljenko, Arun V. Iyer, Sona Chowdhury, Dmitry V. Chouljenko, Konstantin G. Kousoulas

Faculty Publications

Herpes simplex virus type 1 (HSV-1)-induced cell fusion is mediated by viral glycoproteins and other membrane proteins expressed on infected cell surfaces. Certain mutations in the carboxyl terminus of HSV-1 glycoprotein B (gB) and in the amino terminus of gK cause extensive virus-induced cell fusion. Although gB is known to be a fusogenic glycoprotein, the mechanism by which gK is involved in virus-induced cell fusion remains elusive. To delineate the amino-terminal domains of gK involved in virus-induced cell fusion, the recombinant viruses gKΔ31-47, gKΔ31-68, and gKΔ31-117, expressing gK carrying in-frame deletions spanning the amino terminus of gK immediately after the …

The Glycine Plus Serine Requirement Of Broiler Chicks Fed Low-Crude Protein, Corn-Soybean Meal Diets, A. M. Waguespack, S. Powell, T. D. Bidner, L. L. Southern

Faculty Publications

Low-protein, amino acid-supplemented, all-vegetable diets for broilers may not result in optimal FCR unless they are supplemented with Gly. Three experiments were conducted to determine the Gly + Ser requirement in a low-CP, corn- and soybean meal-based diet with 0.25% l-Lys·HCl, a level which previously had been shown to result in optimal growth performance of broilers as long as it is supplemented with Gly to maintain a minimum of 2.32% total Gly + Ser. Glycine addition to the diet did not affect ADG or ADFI but decreased FCR. When the FCR data from all 3 experiments were combined, the total …

High Frequency Of The D Allele Of The Angiotensin-Converting Enzyme Gene In Arabic Populations, Abdel Halim Salem, Mark A. Batzer

Faculty Publications

Background. The angiotensin-converting enzyme (ACE) gene in humans has an insertion-deletion (I/D) polymorphic state in intron 16 on chromosome 17q23. This polymorphism has been widely investigated in different populations due to its association with the renin-angiotensin system. However, similar studies for Arab populations are limited. This study addresses the distribution of the ACE gene polymorphism in three Arab populations (Egyptians, Jordanians and Syrians). Findings. The polymorphisms of ACE gene were investigated using polymerase chain reaction for detection of an I/D mutation. The results showed a high frequency of the ACE D allele among the three Arab populations, Egyptians (0.67), Jordanians …

Statistical Tools For Linking Engine-Generated Malware To Its Engine, Edna Chelangat Milgo

Theses and Dissertations

Malware-generating engines challenge typical malware analysts by requiring them to quickly extract and upload to their customers' machines, a signature for each of a possibly vast number of never-before-seen malware instances that an engine can generate in a short amount of time In this thesis we propose and evaluate two methods for linking variants of engine-generated malware to its engine. The proposed methods use the w-gram frequency vector (NFV) of the opcode mnemonics of an engine-generated malware in- stance as a feature vector for the instance. An NFV is a tuple that maps «-grams with their frequencies. The in-formation contained …

An Organizational Impression Management Perspective On The Formation Of Corporate Reputations, Scott Highhouse, Margaret E. Brooks, Gary J. Gregarus

Research Collection Lee Kong Chian School Of Business

Researchers have only recently turned their attention to the study of corporate reputation.As is characteristic of many early areas of management inquiry, the field is decidedly multidisciplinary and disconnected. This article selectively reviews reputation research conducted mainly during the past decade. A framework is proposed that views reputation from the perspective of organizational impression management. Corporations are viewed as social actors, intent on enhancing their respectability and impressiveness in the eyes of constituents.

Impact Of Culture On ‘Partner Selection Criteria’ In East Asian International Joint Ventures, Ravinder K. Zutshi, Wee Liang Tan

Research Collection Lee Kong Chian School Of Business

Selecting the right partner is important for the success of alliances and joint ventures. For international joint ventures (IJVs) from diverse cultures the partner selection process can become complicated. Prior studies have investigated the alliances and joint ventures to develop a set of objective criteria for evaluating potential partners. This paper reports the study of IJVs formed by Singapore firms in Peoples Republic of China and India. The intent was to develop a methodology for identifying partner selection criteria in a cross-cultural setting. The findings reveal that the partner selection process follows a different logic in Confucian societies. Trust has …

Incomplete Concerted Evolution In The Non-Hybrid Diploid Clematic Fremontii S. Watston (Rananculaceae), Meredith C. Montgomery

Masters Theses and Doctoral Dissertations

Clematis fremontii S. Wats. (Ranunculaceae) is a diploid perennial forb with strict habitat requirements that occurs in isolated populations in the cedar glades of Missouri and the mixed-grass prairies of Kansas and Nebraska. Based on geographical isolation and morphological differences, this species was formerly subdivided into two varieties, the autonymic prairie variety and the glade variety, C. fremontii var. riehlii Erickson. Interestingly, two disjunct populations of C. fremontii inhabit cedar glades have been recently located in Rome, GA and Chattanooga, TN. Initially, the focus of my research was to gain insight into whether the two eastern populations are recent introductions …

A Specification Test For Instrumental Variables Regression With Many Instruments, Yoonseok Lee, Ryo Okui

Cowles Foundation Discussion Papers

This paper considers specification testing for instrumental variables estimation in the presence of many instruments. The test proposed is a modified version of the Sargan (1958, Econometrica 26(3): 393-415) test of overidentifying restrictions. The test statistic asymptotically follows the standard normal distribution under the null hypothesis of correct specification when the number of instruments increases with the sample size. We find that the new test statistic is numerically equivalent up to a sign to the test statistic proposed by Hahn and Hausman (2002, Econometrica 70(1): 163-189). We also assess the size and power properties of the test.
