description: Presented at the 9th international wildlife ranching symposium: wildlife - the key to prosperity for rural communities, held on 12-16 September 2016 at Hotel Safari & the Safari Court, Windhoek, Namibia.
description: Game meat production is considered one of the four pillars of wildlife ranching in South Africa, with the potential to generate large revenues and contribute positively to food security and job creation. It is very far from meeting its potential, however, with the main reason for this being a lack of an enabling legislation to allow for large scale game meat production. This situation is changing, and as the opportunities for game meat production open up, the wildlife ranching industry is planning the way forward. Based on background information on the sector from available literature, interviews with expert stakeholders, as well as data collected during a survey of 250 wildlife ranchers across South Africa, we examine the current and potential scales of the sector and assess the potential future contribution game meat production could make to food security and job creation. Although there are no accurate estimates of current domestic game meat production for South Africa, anecdotal estimates suggest that 10-20% of meat consumed during the hunting season is game meat, which equates to 45,000-118,000 tonnes. By comparison, our study estimated ~40,000 tonnes of game meat were produced during 2014. With the possibility of a new game meat scheme, domestic production could be increased considerably. Producing sustainable sources of protein in social-ecological systems is also touted as a key intervention to possibly reduce bush meat poaching and biodiversity loss. Generating game meat sustainably may thus be win-win for ecologists and the economy.

description: We use the coupled cluster method to investigate the ground-state (GS) properties of the frustrated spin-1/2 $J_{1}$-$J_{2}$-$J_{3}$ model on the honeycomb lattice, with nearest-neighbor exchange coupling $J_1$ plus next-nearest-neighbor ($J_2$) and next-next-nearest-neighbor ($J_3$) exchanges of equal strength. In particular we find a direct first-order phase transition between the Néel-ordered antiferromagnetic phase and the ferromagnetic phase at a value $J_{2}/J_{1} = -1.17 \pm 0.01$ when $J_{1}>0$, compared to the corresponding classical value of -1. We find no evidence for any intermediate phase. From this and our previous CCM studies of the model we present its full zero-temperature GS phase diagram.

description: There is growing concern that the management of persons with psychiatric disabilities after disaster has been inadequate. Unfortunately, the literature is extremely limited, and empirical evidence on the best practices for addressing the needs of persons with psychiatric disabilities after disasters is sparse. A literature search of articles published in 3 widely used databases revealed only 12 articles on the topic. The 12 reviewed articles included persons with psychiatric disabilities after both natural disasters and acts of terrorism, both in close proximity to the disaster site and far away and in 3 different treatment modalities. All of the studies used clinically based samples. The available literature indicated that many persons with psychiatric disabilities demonstrate an ability to handle the stress of a disaster without decompensation from their primary illness. However, the literature also revealed that persons with severe mental illness (SMI) can experience posttraumatic stress disorder (PTSD), depression, anxiety, and illness exacerbation after disaster. There is evidence that persons with SMI can be resilient in the short term when they are enrolled in an assertive community treatment program prior to the disaster however, the outcomes for people with severe mental illness in other treatment modalities are unclear. Well-designed studies with clinical and population-based samples on disaster reactions of persons with psychiatric disabilities are needed for disaster psychiatrists and emergency planners to develop empirically based treatment guidelines for this population.

Generating All Tree Amplitudes in N=4 SYM by Inverse Soft Limit

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The idea of adding particles to construct amplitudes has been utilized in various ways in exploring the structure of scattering amplitudes. This idea is often called Inverse Soft Limit, namely it is the reverse mechanism of taking particles to be soft. We apply the Inverse Soft Limit to the tree-level amplitudes in $\mathcal{N}=4$ super Yang-Mills theory, which allows us to generate full tree-level superamplitudes by adding "soft" particles in a certain way. With the help from Britto-Cachazo-Feng-Witten recursion relations, a systematic and concrete way of adding particles is determined recursively. The amplitudes constructed solely by adding particles not only have manifest Yangian symmetry, but also make the soft limit transparent. The method of generating amplitudes by Inverse Soft Limit can also be generalized for constructing form factors.

description: We prove that every closed set which is not sigma-finite with respect to the Hausdorff measure H^{N-1} carries singularities of continuous vector fields in the Euclidean space R^N for the divergence operator. We also show that finite measures which do not charge sets of sigma-finite Hausdorff measure H^{N-1} can be written as an L^1 perturbation of the divergence of a continuous vector field. The main tool is a property of approximation of measures in terms of the Hausdorff content.

description: Background: The study aim was to determine whether supraphysiological estradiol (E2) levels reduce oocyte/embryo quality in oocyte donation cycles. Methods: A retrospective analysis of 330 consecutive fresh oocyte donation cycles was performed in an assisted reproductive treatment programme between January 1996 and December 2000. Throughout the study period, oocyte donors and recipients followed a standard synchronization regimen that did not vary. A serum E2 level (peak E2) was obtained from all oocyte donors on the morning of HCG administration. Peak E2 values were grouped by 33rd percentile (group I, <1500 pg/ml; group II, 1500-3000 pg/ml; and group III, >3000 pg/ml). All embryo transfers were performed on day 3 after oocyte recovery. Results: Comparisons between groups revealed no significant differences in the quality of oocytes retrieved, and in fertilization rates. Higher peak E2 levels were directly correlated with a greater number of oocytes retrieved, embryos available for transfer and cryopreservation, and higher average embryo quality scores (P < 0.005). Compared with group I, group III had significantly higher embryo implantation rates (P < 0.05). Conclusions: Sustained supraphysiological E2 levels do not adversely affect the quality of developing oocytes and embryos. On the contrary, elevated E2 levels are associated with a larger number of oocytes and embryos and high-grade embryos for transfer/cryopreservation and, consequently, improved implantation rates.
Intracavity generation of high order harmonics
Creators: name: Hammond, Thomas John
Publisher: name: University of British Columbia
Year: 2011

description: The goal of this work is the generation of extreme ultraviolet (EUV) radiation from a laser based source. To this end, we use high harmonic generation (HHG) to convert the near infrared output of a mode-locked Ti:Sapphire laser oscillator to the EUV. The requirement for HHG is a high peak intensity (>10¹³ W/cm²), which can be met by external amplification of the laser output. The method of amplification chosen for this work is a femtosecond enhancement cavity (fsEC), which stores and amplifies the output of a femtosecond mode-locked Ti:Sapphire laser by greater than a factor of 900 while maintaining the original repetition rate of 66 MHz. The design, benefits, and limitations of using a fsEC are discussed. The EUV light is created by the interaction of the amplified light with xenon gas delivered to the fsEC focus. The strong intracavity field leads to xenon plasma generation with detrimental effects on the HHG process, where it is shown that HHG is sensitive to the xenon gas and plasma dynamics. Methods of minimizing the plasma density and maximizing the EUV amplitude are discussed. The EUV is coupled out of the cavity, and up to the thirteenth harmonic (61 nm) of the laser is observed. The relative amplitudes of the different quantum trajectories generating the harmonics are calculated theoretically, and compared to experiment. The generated power of the eleventh harmonic (72 nm) is estimated to be 30μW, with a measured outcoupled power of 1.1μW. The relative intensity noise is also measured, with a cumulative root-mean-square (RMS) noise of <1.2% over 100 Hz - 100 kHz bandwidth. In comparison to other laser based HHG systems, while the EUV flux is similar, the cumulative RMS noise is an order of magnitude lower.

description: Zebra (Equus quagga burchellii) are growing in number in southern Africa, with the meat from surplus animals holding potential to contribute to food security and economic stability. Despite being consumed locally and globally, little information exists on the composition of zebra meat. This study aimed to determine the proximate composition of zebra meat as well as the fatty acid composition of the intramuscular (IMF) and subcutaneous (SCF) fat. Zebra longissimus lumborum muscle was shown to have a high mean protein content (22.29 g per 100g) and low mean fat content (1.47 g per 100 g). High proportions of polyunsaturated fatty acids (PUFAs) were found in the IMF (41.15%) and SCF (37.71%), mainly comprising -linolenic (C18:3n-3) and linoleic (C18:2n-6) acids. Furthermore, the IMF and SCF had favourable PUFA/saturated fatty acid ratios (>0.4) and omega-6/omega-3 ratios (<4), indicating that both components are healthy lipid food sources. This study has shed new light on the nutritional value of zebra meat, which will not only be important for food product labelling, nutritional education and incorporation into food composition databases, but will also be indispensable for marketing and export purposes.

description: This study examined the explanatory models of depression, perceived relationships between diabetes and depression, and depression treatment experiences of low-income, Spanish-speaking, Hispanics with diabetes and depression. A purposive sample (n = 19) was selected from participants enrolled in a randomized controlled trial conducted in Los Angeles, California (United States) testing the effectiveness of a health services quality improvement intervention. Four focus groups followed by 10 in-depth semi-structured qualitative interviews were conducted. Data were analyzed using the methodology of coding, consensus, co-occurrence, and comparison, an analytical strategy rooted in grounded theory. Depression was perceived as a serious condition linked to the accumulation of social stressors. Somatic and anxiety-like symptoms and the cultural idiom of nervios were central themes in low-income Hispanics' explanatory models of depression. The perceived reciprocal relationships between diabetes and depression highlighted the multiple pathways by which these two illnesses impact each other and support the integration of diabetes and depression treatments. Concerns about depression treatments included fears about the addictive and harmful properties of antidepressants, worries about taking too many pills, and the stigma attached to taking psychotropic medications. This study provides important insights about the cultural and social dynamics that shape low-income Hispanics' illness and treatment experiences and support the use of patient-centered approaches to reduce the morbidity and mortality associated with diabetes and depression.

description: The purpose of the present study was to determine the cumulative likelihood of pregnancy success after repetitive cycles of oocyte donation and specifically to examine the influence of recipient age and diagnosis upon the cumulative likelihood of pregnancy in an effort to identify any potential subgroup of recipients who might have diminished endometrial receptivity. We retrospectively analysed the outcome of 418 consecutive embryo transfer cycles among 276 recipients of oocyte donation in our institution. We analysed clinical pregnancy and delivery rates in the recipients divided by age groups and diagnostic groups. For the purpose of life-table analysis, only cycles prior to and including the first cycle producing a successful pregnancy were included. Frozen-thawed embryo transfers were not included in the analysis. The overall clinical pregnancy rate was 36.2% (95% CI 31-41%) and the cumulative pregnancy rate after four cycles was 87.9%. The overall delivery rate was 29.3% (95% CI 25-33%) and the cumulative delivery rate after four cycles was 86.1%. There were no statistically significant differences in any of the rates attributable to recipient age or diagnosis. No decline in per cycle success was noted over consecutive cycles. We conclude that neither recipient age nor diagnosis plays a substantial role in the success of oocyte donation, implying that endometrial receptivity is unaltered by age or diagnosis. Furthermore, up to four successive cycles of oocyte donation are associated with the same probability of success.

description: Multiscale topological complexity of solar magnetic field is among the primary factors controlling energy release in the corona, including associated processes in the photospheric and chromospheric boundaries. We present a new approach for analyzing multiscale behavior of the photospheric magnetic flux underlying this dynamics as depicted by a sequence of high-resolution solar magnetograms. The approach involves two basic processing steps: (1) identification of timing and location of magnetic flux origin and demise events (as defined by DeForest et al., 2007) by tracking spatiotemporal evolution of unipolar and bipolar photospheric regions, and (2) analysis of collective behavior of the detected magnetic events using a generalized version of Grassberger - Procaccia correlation integral algorithm. The scale-free nature of the developed algorithms makes it possible to characterize the dynamics of the photospheric network across a wide range of distances and relaxation times. Three types of photospheric conditions are considered to test the method: a quiet photosphere, a solar active region (NOAA 10365) in a quiescent non-flaring state, and the same active region during a period of M-class flares. The results obtained show (1) the presence of a topologically complex asymmetrically fragmented magnetic network in the quiet photosphere driven by meso- and supergranulation, (2) the formation of non-potential magnetic structures with complex polarity separation lines inside the active region, and (3) statistical signatures of canceling bipolar magnetic structures coinciding with flaring activity in the active region. Each of these effects can represent an unstable magnetic configuration acting as an energy source for coronal dissipation and heating.

Borders Beyond Control

Publisher: name: Columbia University
Year: 2003

description: The article addresses the government's inability to control international migration. According to the author, the reality is that borders are beyond control and little can be done to really cut down on immigration. The author suggests that there must be a seismic shift in the way migration is addressed: governments must reorient their policies from attempting to curtail migration to coping and managing it to seek benefits for all. According to the author, this requires isolating key migration questions from the many other issues that attend the flows of humanity across national borders. The most compelling problems result from emigration from less developed to more developed countries. They arise in three areas: (1) skilled workers are legally emigrating, temporarily or permanently, to rich countries, (2) largely unskilled migrants are entering developed countries illegally and looking for work, and (3) there is the "involuntary" movement of people, whether skilled or unskilled, across borders to seek asylum. All three problems raise issues that derive from the fact that the flows cannot be effectively constrained and must instead be creatively accommodated.

description: This essay explores critical responses to developments in the late-capitalist city, and how those critiques are circumscribed by the very ideology they oppose. I focus on three books that reviewers have identified as among the most provocative recent writing about New York City: Lynne Tillman's No Lease on Life (1998); Mitchell Duneier's Sidewalk (1999); and Samuel Delany's Times Square Red, Times Square Blue (l999)- Each of these texts develops a Utopian vision of the city and each identifies capitalism as the greatest obstacle to that vision; yet in gesturing towards a better city, each ultimately reproduces capitalist ideology. Given the untrammeled course capitalism has taken in the last decades, and given that cities are expressions and engines of capitalism, writers must analyze capitalism's effects in order to understand what cities are. My interest in this paper is in how writers simultaneously fail to analyze capitalism by allowing it to delimit their ideas about what cities could be. As sites that bring large numbers of very different people into relatively close proximity, cities could, more plausibly than suburbs or rural areas, occasion radical social experiments. Cities could encourage the formation of alliances across class and other social divisions that in turn could challenge the very bases for distributing resources and power.
Corruption, Capitalists, and the Crime-State Nexus : Criminal Infiltration of the Russian Economy and Implications for the Future
Creators: name: Willingham, Kelsey Jocelyn Victoria
Publisher: name: Mason Publishing
Year: 2010

description: This paper examines the evolution of organized crime and corruption in relation to the Russian economy, focusing on examples from the banking, energy, and mineral-industrial sectors. An historical perspective of Russian organized crime's economic role during the Soviet Union is provided, followed by an examination of the factors which enabled unprecedented economic infiltration during the transition period and privatization. Next this paper provides an assessment of organized criminal influence in three crucial sectors of the Russian economy: banking, mineral-industrial, and energy. Finally, this paper examines current polices and their shortcomings, and provides a series of policy recommendations for lessening the economic influence of organized crime and ensuring the development of a properly functioning market economy in the Russian Federation and a successful integration with the global economy.

description: The electronic structure and chemical bonding of the recently discovered inverse perovskite Sc3AlN, in comparison to ScN and Sc metal have been investigated by bulk-sensitive soft x-ray emission spectroscopy. The measured Sc L, N K, Al L1, and Al L2,3 emission spectra are compared with calculated spectra using first principle density-functional theory including dipole transition matrix elements. The main Sc 3d - N 2p and Sc 3d - Al 3p chemical bond regions are identified at -4 eV and -1.4 eV below the Fermi level, respectively. A strongly modified spectral shape of 3s states in the Al L2,3 emission from Sc3AlN in comparison to pure Al metal is found, which reflects the Sc 3d - Al 3p hybridization observed in the Al L1 emission. The differences between the electronic structure of Sc3AlN, ScN, and Sc metal are discussed in relation to the change of the conductivity and elastic properties.

description: Over the mid-Atlantic shelf of the North America, there is a pronounced shoreward intrusion of the saltier slope water along the seasonal thermocline, whose genesis remains unexplained. Taking note of the observed broad-band baroclinic motion, we postulate that it may propel the saline intrusion via the shear dispersion. Through an analytical model, we first examine the shear-induced isopycnal diffusivity ("shear diffusivity" for short) associated with the monochromatic forcing, which underscores its varied even anti-diffusive short-term behavior and the ineffectiveness of the internal tides in driving the shear dispersion. We then derive the spectral representation of the long-term "canonical" shear diffusivity, which is found to be the baroclinic power band-passed by a diffusivity window in the log-frequency space. Since the baroclinic power spectrum typically plateaus in the low-frequency band spanned by the diffusivity window, canonical shear diffusivity is simply 1/8 of this low-frequency plateau — independent of the uncertain diapycnal diffusivity. Applied to the mid-Atlantic shelf, this canonical shear diffusivity is about 20 m2 s−1, which is sufficient to account for the observed tracer dispersion or saline intrusion in the thermocline.

description: Micro-capillary liquid-liquid Taylor flows have emerged as a promising new platform for achieving higher heat and mass transfer compared to single-phase flows. In any application benefiting from such flows, pressure drop is a fundamental characteristic in evaluating the required input power in order to achieve an optimum configuration. Despite several attempts to develop an all-encompassing model to estimate pressure drop in immiscible liquid-liquid flows, existing models are still limited to narrow ranges of Reynolds, Capillary and Weber numbers and are insufficiently accurate over a wide range of viscosity ratios. To push the limits, the present study proposes a new expression for interfacial pressure drop based on experimental investigations over a wide range of Capillary (3 × 10− 4 ≤ CaC ≤ 7.6 × 10− 2), Reynolds (0.1 ≤ ReC ≤ 49) and Weber (7 × 10− 4 ≤ We ≤ 1.5) numbers while continuous to dispersed viscosity ratio (μC/μD) spanned from 0.058 to 23.2. To obtain these ranges, five distinct liquid-liquid fluid combinations were examined within a capillary of diameter 800 µm. A novel experimental setup is employed in this study to ensure high accuracy and repeatability of the measurements. The strengths and weaknesses of existing models are identified and a more fundamental understanding of predicting pressure drop in Taylor flow regimes is developed. The new model uses standard Hagen–Poiseuille flow theory in combination with an empirical optimized term for predicting the effect of differential Laplace pressure between leading/trailing caps of dispersed phase droplets. This correlation fits the experimental data within ± 20 % and can provide a prediction certainty for estimating pressure drop in applications that deal with such flows.

description: Real-world applications commonly require untrusting parties to share sensitive information securely. This article describes a secure anonymous database search (SADS) system that provides exact keyword match capability. Using a new reroutable encryption and the ideas of Bloom filters and deterministic encryption, SADS lets multiple parties efficiently execute exact-match queries over distributed encrypted databases in a controlled manner. This article further considers a more general search setting allowing similarity searches, going beyond existing work that considers similarity in terms of error tolerance and Hamming distance. This article presents a general framework, built on the cryptographic and privacy-preserving guarantees of the SADS primitive, for engineering usable private secure search systems.
Parental Resources and Child Abuse and Neglect

description: A child's welfare is affected not only by the wealth of her parents, but also by the quality of care her parents provide. Physical abuse, neglect, and other forms of child maltreatment impose severe hardships on children and may adversely affect them as adults (Cathy Widom, 1989). We examine whether child maltreatment is affected by the socioeconomic circumstances of parents. Our hypothesis is that children are more likely to be maltreated if their parents have fewer resources. We use a broad conception of "resources." It encompasses not only income, but also parental time and the quality of parental time. For example, a low-income working single mother may be short on resources needed to parent not only because she earns a low income, but also because she may not have the physical or emotional reserves to care for her children properly at the end of the day. Likewise, an unemployed father may provide less than adequate parenting not only because his income has been reduced, but also because of the depression and loss of self-esteem that may accompany unemployment (Arthur Goldsniith et al., 1996). We use state-level panel data to analyze the impact that socioeconomic circumstances (in particular, parental work status and single parenthood) have on the incidence of child maltreatment. We find that socioeconomic circumstances do matter. States with higher fractions of children with absent fathers, and especially absent fathers and working mothers, have higher rates of child maltreatment. Nonworking fathers are also associated with higher rates of maltreatment.

description: We present the spectral analysis of three Suzaku XIS observations of 3C 111 requested to monitor the predicted variability of its ultra-fast outflow on ~7 days time-scales. We detect an ionized iron emission line in the first observation and a blue-shifted absorption line in the second, when the flux is ~30% higher. The location of the material is constrained at <0.006pc from the variability. Detailed modelling support an identification with ionized reflection off the accretion disc at ~20-100r_g from the black hole and a highly ionized and massive ultra-fast outflow with velocity ~0.1c, respectively. The outflow is most probably accelerated by radiation pressure, but additional magnetic thrust can not be excluded. The measured high outflow rate and mechanical energy support the claims that disc outflows may have a significant feedback role. This work provides the first direct evidence for an accretion disc-outflow connection in a radio-loud AGN, possibly linked also to the jet activity.

description: Presented at the 9th international wildlife ranching symposium: wildlife - the key to prosperity for rural communities, held on 12-16 September 2016 at Hotel Safari & the Safari Court, Windhoek, Namibia.
description: When looking at market segmentation, age is often used to segment tourism markets. This was also the case with this study, where age was used to perform a market segmentation of South African biltong hunters. The aim was to determine how age affects hunters' behaviour. Data were obtained during the 2015 national hunters' survey. During this time, 492 completed questionnaires were obtained. The results showed that age does affect hunters' behaviour. Firstly, the results revealed that the main motive for hunters to hunt is to escape, to be in nature and to obtain meat; and secondly, age affects hunters' spending and motives to hunt. This research will help product owners to develop different products for hunters based on their age.

description: Este ensaio explora algumas respostas críticas ao desenvolvimento da cidade capitalista nos últimos tempos, e o modo como tais críticas se encontram circunscritas precisamente pela ideologia a que se opõem. Concentro - me em três livros identificados nas recensões como representativos da mais provocativa escrita que recentemente se tem feito sobre a cidade de Nova Iorque: No Lease on Life, de Lynne Tillman (1998); Sidewalk, de Mitchell Duneier (1999); e Times Square Red, Times Square Blue, de Samuel Delany (1999). Cada um destes textos desenvolve uma visão utópica da cidade e cada um identifica o capitalismo como o grande obstáculo a essa visão; porém, ao mesmo tempo que gesticulam pela reivindicação de uma cidade melhor, cada um acaba por reproduzir a ideologia capitalista. Dado o livre curso que o capitalismo tem tomado nas últimas décadas, e dado que as cidades são expressões e máquinas do capitalismo, os escritores devem analisar os efeitos do capitalismo de forma a perceberem o que são as cidades. O meu interesse neste artigo está em demonstrar como os escritores falham na análise do capitalismo, ao permitirem que este delimite as suas ideias sobre aquilo que poderiam ser as cidades. Enquanto lugares que fazem confluir um largo número de gente muito diversa para uma proximidade relativamente estreita, as cidades poderiam, mais plausivelmente do que os subúrbios ou as áreas rurais, dar azo a experiências sociais radicais. As cidades poderiam encorajar a formação de alianças entre classes e outras divisões sociais que, em contrapartida, poderiam desafiar as próprias bases para uma distribuição de recursos e de poder.

description: Decays of X(3872) and its partners as hidden-charm axial-vector tetra-quark mesons are studied. As the result, it is seen that the iso-triplet partners of X(3872) can be broad, and therefore, higher statistics would be needed to find them.

Proprotein convertases and serine protease inhibitors : developing novel indirect-acting antiviral strategies against hepatitis c virus
Creators: name: Olmstead, Andrea D.
Publisher: name: University of British Columbia
Year: 2013

description: Hepatitis C virus (HCV) utilizes host lipids for every stage of its lifecycle. HCV hijacks host lipid droplets (LDs) to coordinate assembly through the host lipoprotein assembly pathway; this facilitates uptake into hepatocytes through the low density lipoprotein receptor (LDLR). Induction of host lipid metabolism by HCV supports chronic infection and leads to steatosis, exacerbating liver dysfunction in infected patients. One pathway activated by HCV is the sterol regulatory element binding protein (SREBP) pathway which controls lipid metabolism gene expression. To activate genes in the nucleus, SREBPs must first be cleaved by host subtilisin kexin isozyme-1/site-1 protease (SKI-1/S1P). Proprotein convertase subtilisin/kexin type 9 (PCSK9) is one SREBP-regulated protein that post-translationally decreases LDLR expression in the liver. The overall aim of this thesis was to determine the potential application of these two important regulators of host lipid homeostasis, PCSK9 and SKI-1/S1P, as targets for inhibiting HCV infection. The first hypothesis tested was that inhibiting SKI-1/S1P would block HCV hijacking of the SREBP pathway and limit sequestration of host lipids by HCV, blocking virus propagation. To inhibit SKI-1/S1P function, an engineered serine protease inhibitor (serpin) and a small molecule inhibitor were employed. Both inhibitors were shown to block SKI-1/S1P cleavage of SREBPs, reduce LD accumulation in hepatoma cells and inhibit HCV infection. The next hypothesis explored was that amplifying PCSK9 expression or function in hepatoma cells would increase their resistance to HCV infection through downregulation of LDLR. It was confirmed, using overexpression of wild-type PCSK9 or treating cells with gain-of-function PCSK9, that PCSK9 can be used to prevent HCV entry into hepatoma cells. Finally, studies are presented detailing the discovery and characterization of a non-inhibitory serpin variant with potent antiviral activity against HCV infection. It is hypothesized that inhibition may be related to antiviral functions exhibited by other human serpins or serpin-derived peptides possessing diverse regulatory properties. Host lipid metabolism is a critical component of the lifecycle of HCV and many other viruses. These studies confirm that lipid metabolism pathways can be rationally targeted to inhibit viral infection and may lead to the development of novel, indirect-acting therapies against HCV and related viruses.
Decoherence, Time Scales and Pointer States

description: Certain issues regarding the time-scales over which environment-induced decoherence occurs, and the nature of emergent pointer states, are discussed. A model system, namely, a Stern-Gerlach setup coupled to a quantum mechanical "heat-bath" is studied. The emergent pointer states for this system are obtained, which are different from those discussed in the literature. It is pointed out that this difference is due to some confusion regarding the decoherence time-scale, which is clarified here.

description: Seismic ground motion can vary significantly over distances comparable to the length of a majority of highway bridges on multiple supports. This paper presents results of fragility analysis of highway bridges under ground motion with spatial variation. Ground motion time histories are artificially generated with different amplitudes, phases, as well as frequency contents at different support locations. Monte Carlo simulation is performed to study dynamic responses of an example multi-span bridge under these ground motions. The effect of spatial variation on the seismic response is systematically examined and the resulting fragility curves are compared with those under identical support ground motion. This study shows that ductility demands for the bridge columns can be underestimated if the bridge is analyzed using identical support ground motions rather than differential support ground motions. Fragility curves are developed as functions of different measures of ground motion intensity including peak ground acceleration, peak ground velocity, spectral acceleration, spectral velocity and spectral intensity. This study represents a first attempt to develop fragility curves under spatially varying ground motion and provides information useful for improvement of the current seismic design codes so as to account for the effects of spatial variation in the seismic design of long-span bridges.
