Cellular Response Of Shewanella Oneidensis To Strontium Stress, Steven D. Brown, Madhavi Martin, Sameer Deshpande, Sudipta Seal, Katherine Huang, Eric Alm, Yungfeng Ynag, Liyou Wu, Tingfen Yan, Xueduan Liu, Adam Arkin, Karuna Chourey, Jizhong Zhou, Dorothea K. Thompson

Faculty Bibliography 2000s

The physiology and transcriptome dynamics of the metal ion-reducing bacterium Shewanella oneidensis strain MR-1 in response to nonradioactive strontium (Sr) exposure were investigated. Studies indicated that MR-1 was able to grow aerobically in complex medium in the presence of 180 mM SrCl2, but showed severe growth inhibition at levels above that concentration. Temporal gene expression profiles were generated from aerobically grown, mid-exponential-phase MR-1 cells shocked with 180 mM SrCl2, and analyzed for significant differences in mRNA abundance with reference to data for nonstressed MR-1 cells. Genes with annotated functions in siderophore biosynthesis and iron transport were among the most highly …

Ultralow Noise Optical Pulse Generation In An Actively Mode-Locked Quantum-Dot Semiconductor Laser, Myoung-Taek Choi, Ji-Myung Kim, Wangkuen Lee, Peter J. Delfyett

Faculty Bibliography 2000s

We report excellent noise performance of an external-cavity actively mode-locked laser based on quantum-dot gain medium. Optical pulse trains with less than 7.5 fs residual timing jitter (1 Hz to 10 MHz) for a 12.8 GHz harmonically mode-locked ring laser were obtained. This result represents, to our knowledge, the lowest residual jitter reported from actively mode-locked semiconductor lasers, and shows that quantum-dot mode-locked lasers are promising as sources of ultralow noise optical pulse trains.

Modeling Of Phase Volume Diffractive Gratings, Part 1: Transmitting Sinusoidal Uniform Gratings, Igor V. Ciapurin, Leonid B. Glebov, Vadim I. Smirnov

Faculty Bibliography 2000s

A detailed model of the diffraction of plane and Gaussian beams on plane uniform phase Bragg gratings based on Kogelnik's theory of coupled waves is presented. The model describes transmitting gratings with arbitrary orientation in a plane-parallel plate taking into account spectral width and angular divergence of laser beams along with material dispersion of a photosensitive medium. The model results are compared with experimental data for high- efficiency Bragg gratings in a photothermorefractive (PTR) glass.

Lasing Mechanisms In Organic Photonic Crystal Lasers With Two-Dimensional Distributed Feedback, K. Forberich, A. Gombert, S. Pereira, J. Crewett, U. Lemmer, M. Diem, K. Busch

Faculty Bibliography 2000s

We present a detailed experimental and theoretical investigation of the lasing characteristics of organic photonic crystal lasers. These lasers are based on strongly modulated two-dimensional polymer surface relief structures on which thin films of optically active organic materials have been deposited. We determine the in-plane photonic band structure of the corresponding quasiguided modes within an effective two-dimensional model. In addition, we calculate the total (three-dimensional) losses associated with these modes. This allows us to identify the lasing thresholds for square lattice geometries and to understand the emission pattern.

Polarization-Independent And Submillisecond Response Phase Modulators Using A 90 Degrees Twisted Dual-Frequency Liquid Crystal, Yuhua Huang, Chien-Hui Wen, Shin-Tson Wu

Faculty Bibliography 2000s

A polarization-independent phase modulator using a 90 degrees twisted dual-frequency liquid crystal (DFLC) is demonstrated. In addition to being polarization independent, such a phase modulator exhibits many other advantages such as being scattering-free and having large phase change, low operating voltage, and submillisecond response time. Using a 15 mu m transmissive DFLC cell, the phase shift achieves 1 pi at lambda = 633 nm and the applied voltage is lower than 25 V-rms. Potential applications of such a phase modulator for laser beam steering, tunable-focus lenses, and switchable two-dimensional/three-dimensional liquid crystal displays are foreseeable.

Spatially Tunable Laser Emission In Dye-Doped Photonic Liquid Crystals, Yuhua Huang, Ying Zhou, Shin-Tson Wu

Faculty Bibliography 2000s

A spatially tunable laser emission of the dye-doped cholesteric liquid crystal (CLC) cell using a one-dimensional temperature gradient is demonstrated. The photoexcitation of dye-doped CLC device using a frequency-doubled pulsed Nd: yttrium-aluminium-garnet laser gives rise to laser emission in the yellow-red spectral range. The lasing wavelength is widely tunable from 577 to 670 nm by shifting the position of the dye-doped CLC cell with respect to the pumping beam. The lowest excitation energy and maximum lasing efficiency occur at lambda similar to 605 nm which corresponds to the peak fluorescence emission of the dye.

Analysis Of Proline Reduction In The Nosocomial Pathogen Clostridium Difficile, Sarah Jackson, Mary Calos, Andrew Myers, William T. Self

Faculty Bibliography 2000s

Clostridium difficile, a proteolytic strict anaerobe, has emerged as a clinically significant nosocomial pathogen in recent years. Pathogenesis is due to the production of lethal toxins, A and B, members of the large clostridial cytotoxin family. Although it has been established that alterations in the amino acid content of the growth medium affect toxin production, the molecular mechanism for this observed effect is not yet known. Since there is a paucity of information on the amino acid fermentation pathways used by this pathogen, we investigated whether Stickland reactions might be at the heart of its bioenergetic pathways. Growth of C …

A Brief Critique Of The Emaciated State And Its Reliance On Non-Governmental Organizations To Provide Social Services, Dana Neacsu

Law Faculty Publications

When, in January 2006, seven-year-old Nixzmary Brown was tortured and beaten to death, allegedly by her stepfather as her mother ignored her cries for help, every New Yorker looked at the city's Administration for Children's Services for answers. Conversely, I do not recall any discussion about the failure of charities to adequately provide for the city's abused children. Charities, like non-governmental organizations (NGOs), are not expected to be responsible for systemic problems. They are a moral and social bonus, which fill the gap in discrete areas where taxpayers' money is not sufficient. So I may be accused of having a …

Setting The Pole: Critical Factors In Nascar's Success, Matthew N. Maisano

Seton Hall University Dissertations and Theses (ETDs)

This study examines the critical factors that make NASCAR so successful. Now known as the fastest growing sport, NASCAR started out as a limited funding, dirt track racing sport to a multimillion dollar, super speedway sport. Just like every sport, NASCAR has gone through many changes and this study will further discuss how it went from a sport to a business and then to entertainment and now a lifestyle. In the beginning NASCAR drivers were renegades with ties to moonshining; today drivers are considered role models and are active in Pop Culture. Constant changes in the sport have allowed it …

Constructing A New Game: J.K. Rowling’S Quidditch And Global Kid Culture, Terri Toles Patkin

Reconstruction: Studies in Contemporary Culture

As part of her wildly popular Harry Potter fantasy series, author J.K. Rowling created a setting of magical characters to populate magical towns, perform magical jobs, purchase magical products -- and play a magical game called Quidditch. This fast-paced team sport played on broomsticks is both a participant and a spectator sport, and forms a nucleus of leisure activity and discourse in the Harry Potter books. From preschoolers to professionals, wizards in Rowling's world incorporate this virtual sport into their everyday lives. Rowling's development of Quidditch -– some have suggested that Rowling's intense dislike of school hockey practices sparked the …

You Need Love And Friendship For This Mission!: The Final Fantasy Series As Social Education For Japanese Youth, Ben Hourigan

Reconstruction: Studies in Contemporary Culture

From the mid to late 1990s, popular and academic discourse on video games, particularly in the United States, has focused on their supposed capacity to engender violent and otherwise anti-social behavior in youth. Much like ludologists' recent claims that video games are not a narrative medium, at least one reason for this is that commentators have too narrow an understanding of the diverse range of games that exist. In addition to this, game demonizers have demonstrated an inadequate understanding of the ways games are related to real life. In order to combat these misunderstandings, this chapter analyzes the role of …

Little Gods And Little Heroes: Hyperreal Ethics In God Games And Online Gaming, G. Christopher Williams

Reconstruction: Studies in Contemporary Culture

Media critics, notably Jean Baudrillard, have suggested that the environment of simulations are to be defined as something more real than the real, or, in his terms, hyperreal. If hyperrealities are indeed the way that we can define the environment of multimedia technologies like video games, what sorts of ethical considerations should exist in a place that gamers conceive as more real than the real? This essay considers what ethical considerations are worth contemplating as gamers begin to take on the roles of gods and heroes in multiplayer video games. The little gods and heroes whose identities gamers have begun …

Cyanidin-3-Glucoside, A Natural Product Derived From Blackberry, Exhibits Chemopreventive And Chemotherapeutic Activity, Min Ding, Rentian Feng, Shiow Y. Wang, Linda Bowman, Yongju Lu, Yong Qian, Vincent Castranova, Bing-Hua Jiang, Xianglin Shi

Faculty & Staff Scholarship

Epidemiological data suggest that consumption of fruits and vegetables has been associated with a lower incidence of cancer. Cyanidin-3-glucoside (C3G), a compound found in blackberry and other food products, was shown to possess chemopreventive and chemotherapeutic activity in the present study. In cultured JB6 cells, C3G was able to scavenge ultraviolet B-induced *OH and O2-* radicals. In vivo studies indicated that C3G treatment decreased the number of non-malignant and malignant skin tumors per mouse induced by 12-O-tetradecanolyphorbol-13-acetate (TPA) in 7,12-dimethylbenz[a]anthracene-initiated mouse skin. Pretreatment of JB6 cells with C3G inhibited UVB- and TPA-induced transactivation of NF-kappaB and AP-1 and expression of …

The Everyday Life Of Playing Cards, Ruralism, And The Case Of Russian Peasantry, Anna N. Kushkova

Reconstruction: Studies in Contemporary Culture

This chapter addresses the issue of card playing in the Russian village of the second half of the nineteenth century. The author challenges a widely spread stereotype that Russian peasants did not play in any other way that merely for fun or for entertainment, but rather shows that this view is inconsistent with historical reality, which places card play at the center of daily social life. Social changes of village life after peasants' emancipation (1861) brought about systematic contacts of rural and urban population in many provinces of the country. As a result, a number of city habits and practices …

More Than Girlfriends, Geekettes, And Gladiatixes: Women, Feminism, And Fantasy Role-Playing Games, Rebecca Borah, Inez Schaechterle

Reconstruction: Studies in Contemporary Culture

[First paragraph]

The only function women have in D&D is to serve cookies. Gary Gygax, the most well known of the creators of Dungeons & Dragons, claims he did not make this remark (Gel214th). That he did or not is perhaps, some thirty years after the introduction of the first fantasy role-playing game, of concern only to him. The problematic position of women players is a secure feature of the RPG zeitgeist. While few male gamers may openly challenge the assumption that women can or should play fantasy role games such as Dungeons & Dragons, the function of …
