title: Online opera: an applied collision of opera and web creativity
Creators: name: Scott, L.T.D
Publisher: name: Bath Spa University
Year: 2021

description: This practice-based research explores the collision of opera and web creativity through the development and evaluation of a new 'online opera' called "The Village" (2015). Contrasting existing offerings that position the web as a means of disseminating more familiar representations of opera, "The Village" draws on concepts of participatory culture, digital storytelling and co-creativity to advance a culturally novel apprehension of online opera that treats the web as a unique creative space. This interpretation is intrinsically digital, unable to be realised through conventional forms of theatrical presentation, and transformative in its approach to the core elements of opera. "The Village" in additional serves as a vehicle to investigate how the phenomenon of 'liveness' - that is, a feeling of 'now-ness' experienced in live performance - may be reimagined in the context of an entirely mediated opera. A range of theoretical perspectives are drawn on to establish a set of liveness devices that attempt to evoke in visitors to "The Village" a sense of contemporaneity and shared experience. These include temporal alignment between virtual and real-world events and the facilitation of social interaction through a narrative mechanism called the 'Digital Chorus', amongst others. Evaluative activities critique the effectiveness of such devices, and offer means in which they may be modified to better construct 'the live'.

description: Using X-ray stacking analyses we estimate the average amounts of supermassive black hole (SMBH) growth taking place in star-forming galaxies (SFGs) at z~1 and z~2 as a function of galaxy stellar mass (M*). We find the average SMBH growth rate follows remarkably similar trends with M* and redshift as the average star-formation rates (SFRs) of their host galaxies (i.e., (i.e., dM_BH/dt ~ M*^(0.86+/-0.39) for the z~1 sample and dM_BH/dt ~ M*^(1.05+/-0.36) for the z~2 sample). It follows that the ratio of SMBH growth rate to SFR is (a) flat with respect to M* (b) not evolving with redshift and (c) close to the ratio required to maintain/establish a SMBH to M* ratio of ~10^{-3} as also inferred from today's M_BH-M_bulge relationship. We interpret this as evidence that SMBHs have, on average, grown in-step with their host galaxies since at least z~2, irrespective of host galaxy mass and AGN triggering mechanism. As such, we suggest that the same secular processes that drive the bulk of star formation are also responsible for the majority of SMBH growth. From this, we speculate that it is the availability of gas reservoirs that regulate both cosmological SMBH growth and star formation.

Natural disasters--Planning

description: Within hours after Hurricane Sandy’s landfall, doctors and staff at one of New York City’s premier medical centers realized that something was going terribly wrong. Lights were flickering, critical devices essential to life support for more than 200 patients, many in intensive care units, were malfunctioning. A decision had to be made by hospital leaders, senior public health officials, and emergency responders: tough it out in a hospital without power or attempt a perilous patient evacuation as an epic disaster unfolded. With little time to lose, the “go” order was given, followed by frantic calls to high-ground hospitals identifying beds for receiving New York University–Langone Medical Center’s critically ill patients. St. Luke’s–Roosevelt, Mt. Sinai, New York Presbyterian at Columbia, and many other hospitals responded immediately, opening beds, readying emergency admission procedures, and briefing staff. But questions about why these extreme measures were necessary will have to be answered in the months ahead. Although the first question may be how to prevent power failure, the nuances of backup and redundant power generation are not generally within the expertise of health professionals. And in fact, the generators themselves were probably fine; the problem appears to have been that fuel pumps supplying the generators were in the basement, highly susceptible to break- down from flooding. Ways of ensuring resiliency of backup power equipment will certainly be investigated later. For now, it’s important to understand what medical and public health challenges are to be expected after mega-disasters such as Hurricane Sandy.

description: Background: Seizures are often followed by a period of transient neurological dysfunction whereby sensory, cognitive, or motor abilities are impaired. Alterations in cerebral blood flow (CBF) during the postictal period has been proposed as a possible mechanism for this phenomenon. Recent animal studies have shown reduced local CBF at the seizure onset zone (SOZ) lasting up to one hour following seizures (Farrell, et al., 2016). Using arterial spin labeling magnetic resonance imaging (ASL MRI), we have observed postictal hypoperfusion at the SOZ in 75% of patients lasting up to one hour (Gaxiola-Valdez, 2017). The clinical implementation of ASL as a novel tool to identify the SOZ is hampered by the limited availability of MRI on short notice. Computed tomography perfusion (CTP) also measures CBF changes and may circumvent the logistical limitations of MRI. Methods: Fifteen patients with drug resistant focal epilepsy admitted for pre-surgical evaluation were prospectively recruited and underwent CTP scanning within 80 min of a habitual seizure. Patients underwent a second scan in the interictal period after they were seizure-free for at least 24 hours. The acquired scans were visually assessed for perfusion differences and quantitatively assessed to identify areas of significant postictal hypoperfusion. Results: Postictal reductions of >15 CBF units (ml/100g-1/min-1) were seen in 12/15 patients. In 10 of these patients, the location of the hypoperfusion was partially or fully concordant with the presumed SOZ, and all patients localized additional areas of seizure propagation concordant with their electroencephalography (EEG). Conclusions: Postictal hypoperfusion can be measured by CTP. Thus, CTP has the potential to be a cost-effective and readily available tool in localizing the SOZ by measuring postictal CBF changes.
Effect of Plumes on Measuring the Large Scale Circulation in Turbulent Rayleigh-Bénard Convection

description: We studied the properties of the large-scale circulation (LSC) in turbulent Rayleigh-Bénard (RB) convection by using results from direct numerical simulations in which we placed a large number of numerical probes close to the sidewall. The LSC orientation is determined by either a cosine or a polynomial fit to the azimuthal temperature or azimuthal vertical velocity profile measured with the probes. We study the LSC in Γ=D/L=1/2 and Γ=1 samples, where D is the diameter and L the height. For Pr=6.4 in an aspect ratio Γ=1 sample at $Ra=1\times10^8$ and $5\times10^8$ the obtained LSC orientation is the same, irrespective of whether the data of only 8 or all 64 probes per horizontal plane are considered. In a Γ=1/2 sample with $Pr=0.7$ at $Ra=1\times10^8$ the influence of plumes on the azimuthal temperature and azimuthal vertical velocity profiles is stronger. Due to passing plumes and/or the corner flow the apparent LSC orientation obtained using a cosine fit can result in a misinterpretation of the character of the large-scale flow. We introduce the relative LSC strength, which we define as the ratio between the energy in the first Fourier mode and the energy in all modes that can be determined from the azimuthal temperature and azimuthal vertical velocity profiles, to further quantify the large-scale flow. For $Ra=1\times10^8$ we find that this relative LSC strength is significantly lower in a Γ=1/2 sample than in a Γ=1 sample, reflecting that the LSC is much more pronounced in a Γ=1 sample than in a Γ=1/2 sample. The determination of the relative LSC strength can be applied directly to available experimental data to study high Rayleigh number thermal convection and rotating RB convection.

Risk-based design of horizontal curves with restricted sight distance
Creators: name: Ibrahim, Shewkar El-Bassiouni
Publisher: name: University of British Columbia
Year: 2011

description: Current geometric design guides provide deterministic standards where the safety margin of the design output is generally unknown and there is little knowledge on the safety implications of deviating from these standards. Several studies have advocated probabilistic geometric design where reliability analysis can be used to account for the uncertainty in the design parameters and to provide a risk measure of the degree of deviation from design standards. In reliability analysis, this risk is represented by the probability of non-compliance (Pnc) defined as the probability that the supply exceeds the demand. However, there is currently no link between measures of design reliability and the quantification of safety using collision frequency. The analysis presented in this thesis attempts to incorporate a reliability-based quantitative risk measure in the development of Safety Performance Functions (SPFs). The thesis considers the design of horizontal curves, where non-compliance occurs whenever the available sight distance (ASD; supply) falls short of the stopping sight distance (SSD; demand). The inputs of SSD are random variables and appropriate probability distributions were assumed for each. A comprehensive database for the Trans-Canada Highway was used to compute the probability of non-compliance (Pnc) for 100 segments of horizontal curves. Several Negative Binomial (NB) Safety Performance Functions (SPFs) were developed and the predicted collisions were found to increase with risk (Pnc) and that the rate of increase varies by severity level. The likelihood ratio test showed that the inclusion of a risk parameter (Pnc) has generated better predictive models that have significantly outperformed the traditional models. Further, a spatial analysis was carried out which showed that the spatial models were successful in overcoming potential model misspecification resulting from incorporating only exposure and Pnc in the SPFs as relevant covariates might have been omitted. The optimization of cross-section design to minimize the risk associated with restricted sight distance was also considered using a multiple objective function that involves new Collision Modification Factors (CMFs) incorporating Pnc. The results indicated that accounting for the random variations due to drivers’ behavior proactively at the design stage would decrease collisions in addition to achieving an overall risk reduction.
New GNSS Navigation Messages for Inherent Fast TTFF and High Sensitivity - Underlying Theory Study and System Analysis

description: In the navigation applications on mobile devices, the extreme demands for fast Time To First position Fix (TTFF) and high sensitivity have been driving the technology innovations in these areas in recent years. Assisted GNSS (AGNSS) and Ephemeris Extension (EE) technologies constitute the efforts to improve the TTFF and sensitivity. However, it is challenging for both AGNSS and EE. For AGNSS, while it attempts to improve TTFF on sensitivity on mobile devices, it is subject to frequent ephemeris expiration and therefore it requires the mobile devices to be always or frequently connected to the assisting networks. For EE - a technology complementary to the AGNSS to improve TTFF, although it requires little connectivity to assisting networks by directly using some extended ephemerides (valid for days) in the first position fix, such extended ephemerides can be hardly used as the aiding data for tracking weak signals. In the analysis of the challenges, this thesis points out that, such challenges are originated from the weakness in the fundamental design of the existing GNSSs – the life expectancy of ephemeris is too short. Then this thesis proposes an alternative solution for future GNSSs, to fundamentally resolve the above issues by broadcasting some new navigation (NAV) messages with validity for up to 24 hours instead of those used by current GNSSs. Through the study of the TTFF and sensitivity fundamentals, this thesis fully explains how the ephemeris life expectancy relates to TTFF and sensitivity; and through fundamental study on orbital determination theories and ephemeris extension practices, this thesis confirms the feasibility to obtain long-validity ephemerides; and through some simulated uses of the long-validity ephemerides in some typical scenarios, this thesis further confirms the navigation availability and accuracy using the proposed new NAV messages are comparable to those using the current NAV messages. Therefore, for a GNSS that deploys the proposed NAV messages, the capability to achieve fast TTFF and high sensitivity on a mobile device is inherently enhanced, with minimum or even no reliance on assisting infrastructures.

Public health--Evaluation

description: This study aimed to examine a range of factors influencing the long-term recovery of New York City residents affected by Hurricane Sandy. In a series of logistic regressions, we analyzed data from a survey of New York City residents to assess self-reported recovery status from Hurricane Sandy. General health, displacement from home, and household income had substantial influences on recovery. Individuals with excellent or fair health were more likely to have recovered than were individuals with poor health. Those with high and middle income were more likely to have recovered than were those with low income. Also, individuals who had not experienced a decrease in household income following Hurricane Sandy had higher odds of recovery than the odds for those with decreased income. Additionally, displacement from the home decreased the odds of recovery. Individuals who applied for assistance from the Build it Back program and the Federal Emergency Management Agency had lower odds of recovering than did those who did not apply. The study outlines the critical importance of health and socioeconomic factors in long-term disaster recovery and highlights the need for increased consideration of those factors in post-disaster interventions and recovery monitoring. More research is needed to assess the effectiveness of state and federal assistance programs, particularly among disadvantaged populations.

title: Developing a hydrofeminist art practice: bodies, spaces, practices

Publisher: name: Bath Spa University
Year: 2022

description: This research presents primary work that has been situated in the city of Plymouth (UK) – Benthic Caress (2017), Hydrosapien (2018) and Manual for Nomads (2020), supported by three bodies of exploratory work (Interim, Rhyne & Huish, Field Notes). Documentation of the work can be found here: https://aquameteor.wordpress.com/ This is a practice led PhD that seeks to make a contribution to knowledge by developing the concept of hydrofeminism, through practice. This work is practice-driven, and consciously situated within Environmental Humanities, and this thesis is foundationally and iteratively entangled with the practice. The thesis is undertaken in an interdisciplinary location of intersecting artistic practices, feminisms, posthumanism and cultural geographies, aiming to fold these entanglements into the emerging field of environmental humanities (Bird-Rose et al 2012). It is done through practice led research, thus extending hydrofeminism from its academic (text based) foundation in the work of Neimanis (2012). Water, specifically oceans, estuaries, rivers and other ‘natural’ bodies of water (including puddles) has been the material signifier across the body of work shared here, which is transdisciplinary and which has investigated hydrofeminism using a wide range of creative tools. The creative practice presented here is about water, explored through feminisms, hydrofeminism, transcorporeality, posthumanism and embodiment. Benthic Caress was a site-specific and site-responsive immersive experience that offered participants a sonic engagement with marine life using silent disco technologies. Hydrosapien was a public performance of a section of Hydrofeminism (Neimanis 2012) that pertains to ecotones, presented by a Silent Choir and two experimental voice artists. Manual for Nomads is a short film exploring community and the climate crisis that brings the languages, codes and methods of communication of differently abled persons together to create new conceptualisations of the ecotone.
Tagged particle in a sheared suspension: effective temperature determines density distribution in a slowly varying external potential beyond linear response

description: We consider a sheared colloidal suspension under the influence of an external potential that varies slowly in space in the plane perpendicular to the flow and acts on one selected (tagged) particle of the suspension. Using a Chapman-Enskog type expansion we derive a steady state equation for the tagged particle density distribution. We show that for potentials varying along one direction only, the tagged particle distribution is the same as the equilibrium distribution with the temperature equal to the effective temperature obtained from the violation of the Einstein relation between the self-diffusion and tagged particle mobility coefficients. We thus prove the usefulness of this effective temperature for the description of the tagged particle behavior beyond the realm of linear response. We illustrate our theoretical predictions with Brownian dynamics computer simulations.

description: This project investigated whether variation existed in durations of maternal and nonmaternal received by infants (when controlling for infant age) in wild Colobus vellerosus monkeys. I examined whether variation in handling durations was associated with infanticide risk using behavioral data collected from 16 infants ranging in age from newborn to 78 weeks. Maternal handling constituted the bulk of ‘total’ handling received by infants. Individuals varied in the duration of handling they received. Less maternal handling occurred in unstable groups, and male infants receiving more handling. Neither maternal nor nonmaternal handling responded to all infanticide risk factors. These results suggest that handling is a flexible behavior, but it is not yet entirely clear what factors handlers respond to, and why. One potential explanation is that, when infanticide poses a higher threat, mothers decrease infant-contact time to facilitate faster infant development while nonmothers increase handling as a form of protection.

description: This study explored the emerging field of social work practice within Canadian public libraries. This is an interdisciplinary area of practice that has been increasing in prevalence across North America over the last decade. Despite the burgeoning movement that has begun to gain attention within public library circles and the popular media, comparatively little research has been published on library social work practice. There is a particular dearth of research in the area from Canadian social work perspectives. A mixed methods multicase study was utilized, consisting of a preliminary online survey distributed across Canada followed by analysis of four cases in which there are library-based social workers: Thunder Bay Public Library (TBPL), Kitchener Public Library (KPL), Mississauga Public Library (MPL), and Edmonton Public Library (EPL). Semi-structured interviews were conducted with 17 participants, along with document review. Analysis was first performed for each individual case, followed by cross-case analysis. Four library social work models used by the urban public libraries were identified: social service agency partnership, local university partnership, municipal partnership, and full-time social work staff. In addition to the models, the major themes identified are grouped into two categories: public library motivations for including social workers within their operations, and the nature of social work practice in these settings. Primary findings indicate that library social work is an emerging distinct area of interdisciplinary practice that shows promise at individual and systems levels in helping to address social exclusion and improve community-based responses to broader social challenges such as homelessness, housing instability, poverty, mental health concerns, and substance misuse. Implications for social work and public library research and practice are provided.

description: Brittleness and fracability evaluation plays an important role in recovery of unconventional oil and gas; it directly influences the effect of hydraulic fracturing. The definition of brittleness is controversial and the existing analytical/semi-analytical models have no unified theory to support them. Brittleness and fracability evaluation is currently unreliable. Unconventional reservoirs have different confining pressure, pore pressure and temperature. Models that do not consider these influences lack accuracy in the brittleness index (BI) calculation, resulting in failure during hydraulic fracturing. This research is focused on establishing new methods for brittleness and fracability evaluation. First, analytical/semi-analytical models are proposed considering the influence of confining pressure, pore pressure and temperature, respectively. The influence of calcite on rock mechanics parameters and brittleness is compared to quartz and clay. The weight of each parameter in models based on elastic modulus and mineralogy is analyzed. Finally, a numerical method to evaluate rock brittleness in terms of energy is developed. This novel method is applied to evaluate rock brittleness and fracability in more complicated conditions by considering hydro-mechanical (HM) interaction. By defining brittleness in terms of energy, rock brittleness from different sources can be compared. The influence factors ignored by other models of brittleness evaluation: pressure, temperature and rock texture can be addressed at the same time. By combining the analytical method and the numerical method for brittleness and fracability the resulting evaluations are more applicable because they reflect a more realistic unconventional oil and gas reservoirs environment.

description: Two-loop corrections for the standard Abelian Nambu-Jona-Lasinio model are obtained with the Optimized Perturbation Theory (OPT) method. These contributions improve the usual mean-field and Hartree-Fock results by generating a $1/N_c$ suppressed term, which only contributes at finite chemical potential. We take the zero temperature limit observing that, within the OPT, chiral symmetry is restored at a higher chemical potential $μ$, while the resulting equation of state is stiffer than the one obtained when mean-field is applied to the standard version of the model. In order to understand the physical nature of these finite $N_c$ contributions, we perform a numerical analysis to show that the OPT quantum corrections mimic effective repulsive vector-vector interaction contributions. We also derive a simple analytical approximation for the mass gap, accurate at the percent level, matching the mean-field approximation extended by an extra vector channel to OPT. For $μ\gtrsim μ_c$ the effective vector coupling matching OPT is numerically close (for the Abelian model) to the Fierz-induced Hartree-Fock value $G/(2N_c)$, where $G$ is the scalar coupling, and then increases with $μ$ in a well-determined manner.

‘doubly/twofold’. We explore the contrasts between the expressions in question

including the interaction with comparatives and equatives as well as scope asymmetries. We propose that degree numerals target values on a provided scale and

are, hence, best analyzed as predicates of degrees whereas event numerals have a

more general semantics which primarily allows for quantification over individuated events, but also enables to operate on degrees.

description: I would like to provide a new angle on the Occupy Movement from a Christian point of view, specifically from the standpoint of my own work as a Christian theologian. Christians, I believe, should be supportive of the Occupy Movement and not simply for the obvious religious reasons. What are those obvious reasons? Christian concerns about social justice, Christian concerns especially for the poor, for all those disadvantaged and downtrodden, marginalized and harmed by forms of social exclusion and exploitation—such concerns clearly overlap with issues that the Occupy Movement has now brought to the forefront of our national consciousness: economic inequity and the economic plight of the 99 percent woefully underserved by our political and economic system since the financial crisis hit. Christianity and the Occupy Movement are closely aligned on these grounds of shared concern—concerns about injustice and about the economic disadvantage suffered by so many. But more than this, I believe that basic beliefs of Christianity contain an alternative vision of economic life that helps make sense of and pull together coherently the multiple strands of our economic and political predicament targeted for protest by the Occupy Movement—that’s what I want to argue now. I’ll try to show what this alternative Christian vision for our economic lives is, what the multiple concerns of the Occupy protest are, and how that Christian vision of economy brings those multiple strands of protest together.

description: The structure and energy of saddle point (SP) states in 2D superconducting film of finite width $w$ with transport current $I$ are found in the framework of Ginzburg-Landau model. We show that very near depairing current $I_{dep}$ the SP state with a vortex does not exist and it transforms to 2D nucleus state, which is a finite region with partially suppressed order parameter. It is also shown that for slightly lower currents the contribution of the vortex core energy is important for SP state with a vortex and it cannot be neglected for $I\gtrsim 0.6 I_{dep}$. It is demonstrated that in the film with local current concentration near the bend the energy of SP state may be much smaller than one in the straight film and it favors the effect of fluctuations in such a samples.

The proposed algorithm is a modification of a simple ACS for the TSP improved by an efficient GTSP-specific local search procedure. Our extensive computational experiments show that the use of the local search procedure dramatically improves the performance of the ACS algorithm, making it one of the most successful GTSP metaheuristics to date.

description: The mechanism leading to the formation of the observed products of the collinear cluster tripartition is carried out within the framework of the model based on the dinuclear system concept. The yield of fission products is calculated using the statistical model based on the driving potentials for the fissionable system. The minima of potential energy of the decaying system correspond to the charge numbers of the products which are produced with large probabilities in the sequential fission (partial case of the collinear cluster tripartition) of the compound nucleus. The realization of this mechanism supposes the asymmetric fission channel as the first stage of sequential mechanism. It is shown that only the use of the driving potential calculated by the binding energies with the shell correction allows us to explain the yield of the true ternary fission products. The theoretical model is applied to research collinear cluster tripartition in the reaction $^{235}$U(n$_{\rm th}$,f). Calculations showed that in the first stage of this fission reaction, the isotopes $^{82}$Ge and $^{154}$Nd are formed with relatively large probabilities and in the second stage of sequential fission of the isotope Nd mainly Ni and Ge are formed. This is in agreement with the yield of the isotope $^{68}$Ni which is observed as the product of the collinear cluster tripartition in the experiment.

description: A Guardedly Hopeful Prognosis There is a distinct possibility that our human species, the first life form on this planet to achieve thought, may be terminally ill. We may be fatally flawed, destined for only a short tenure in this privileged little corner of our universe. But, summoning resolve, I will begin on a strained but modestly hopeful note. Then, and only then, will I make the painful plunge into an analysis of the human inter- national, multi-disciplinary myopia that may be our undoing, just as it has already contributed to the undoing of myriad species on this gifted planet. But first, the determined reach for hope. In our day the three primal violences have been uncovered. Sexism, its cousin heterosexism, and that other form of violence, called militarism, have been diagnosed. They haven’t been cured, but they have been spotted and seismic plates are crashing in church and state as we address them. Panic abounds quite understandably, as we dare to rearrange the stubbornly tenured bases and biases of intelligent life on earth. Male and female were we made, with many variations on those dyadic themes. The problem was we tried to run the world monadically; we perversely opted for a male-run world on the macho model, and it hasn’t worked. It has been waggishly and wisely said that if Lehman Brothers had been Lehman Brothers and Sisters, it would not have failed. Complementarity is at our core. From the chromosomes on up we find difference, not sameness, at the center of our being.

description: "If you visit my city, Buenos Aires, please try and go see the women lemon vendors who sit in the streets of some neighborhoods." No, rather, I welcome you now to Buenos Aires. In your theological imagination, I welcome you. I, Marcella, will be your guide for a few sentences. Here is the marketplace of Constitución, where my mother would buy chickens still warm. Do you see those stray dogs over there sleeping quietly in the door of the abandoned building? This is my barrio, San Telmo. Shall we sit for a few minutes over cortado? It is a good place to think– to think about postmodernism, liberation, the destruction of grand meta-narratives. The first few pages of Indecent Theology invite us into Marcella Althuas-Reid’s world. She tantalizes our senses: sights, sounds, tastes, and smells. Bodies come to life. Places materialize. Histories swirl with their tangled and complicated interplay. Our eyes roam. We not only see women selling lemons in the marketplace; our journey continues under their skirts, into their baskets. We hover in the midst of their interactions. Women without underwear, whose musky smell mixes with the scent of lemons and market. Skirts lifted: exposed, smelled, seen - by Althaus-Reid. Skirts lifted: exposed, smelled, seen - by us.

Phase I Archaeological Survey
Archaeological Overview
Records Search / Inventory Checking
Systematic Survey

description: A Phase I archaeological survey was conducted for Areas 4100 and 4200 at McGuire Air Force Base in Burlington County, New Jersey. The area of these parcels is 48.06 acres (Area 4100) and 29.59 acres (Area 4200). Military use of these parcels, once part of Fort Dix, dates from World War I. Temporary World War II wooden, single-story hospital structures stood here until they were demolished in the 1960s and 1970s. A warehouse (Building 4145) in the eastern portion of Area 4100 is currently used. At the northern perimeter of Area 4100 is a railroad grade from which ties and tracks have been removed. Concrete curbing, drains, and utility lines are in both areas. Forests and brushy fields have grown around roads and building sites. The ground is level, and the soil is classified as Urban Land.

All of the land surface was inspected. Intensive surface inspection did not find any cellar holes or foundations. Subsurface testing was done at 50-ft (15-m) intervals in areas that did not show obvious surface disturbance. When disturbance was not evident, shovel test pits were excavated to culturally sterile subsoil and recorded with a Munsell Color Chart. In Area 4100, 155 shovel test pits and 201 shovel probes were excavated. In Area 4200, 81 shovel test pits and 67 shovel probes were excavated. Only a few artifacts were found in Area 4100 and none in Area 4200. These artifacts date from the early 1900s and may be associated with the Harker location.

Elsewhere in the project areas, no prehistoric sites or historic sites of integrity dating from before the military use of the properties were encountered. Artifacts were recovered from all survey units in each area. Among them are asphalt and concrete fragments; plastic, metal, and ceramic pipes; tar paper; coal slag; and recent trash. No further research is recommended in either Area 4100 or 4200.
Connecting flow structures and heat flux in turbulent Rayleigh-Bénard convection

description: The aspect ratio (Γ) dependence of the heat transfer (Nusselt number Nu in dimensionless form) in turbulent (two-dimensional) Rayleigh-Bénard convection is numerically studied in the regime $0.4 \le Γ\le 1.25$ for Rayleigh numbers $10^7 \le Ra \le Ra^{9}$ and Prandtl numbers Pr =0.7 (gas) and 4.3 (water). Nu (Γ) shows a very rich structure with sudden jumps and sharp transitions. We connect these structures to the way the flow organizes itself in the sample and explain why the aspect ratio dependence of Nu is more pronounced for small Pr. Even for fixed Γdifferent turbulent states (with different resulting Nu) can exist, between which the flow can or cannot switch. In the latter case the heat transfer thus depends on the initial conditions.

Minimum Hellinger Distance Estimation of ARCH/GARCH Models

description: In this thesis, we proposed a minimum Hellinger distance estimator (MHDE) and a minimum profile Hellinger distance estimator (MPHDE) for estimating the parameters in the ARCH and GARCH models depending on whether the innovation distribution is specified or not. The asymptotic properties of MHDE and MPHDE were examined through graphs as the theoretical investigation of them are more involved and needs further study in the future research. Moreover, we demonstrated the finite-sample performance of both MHDE and MPHDE through simulation studies and compared them with the well-established methods including maximum likelihood estimation (MLE), Gaussian Quasi-MLE (GQMLE) and Non-Gaussian Quasi-MLE (NGQMLE). Our numerical results showed that MHDE and MPHDE have better performance in terms of bias, MSE and coverage probability (CP) when the data are contaminated, which testified to the robustness of MHD-type estimators.

description: Astrocytes can control local cerebral arteriole tone through Ca2+ dependent mechanisms. Modest elevations of the external K+ concentration in the brain are thought to have little effect on astrocyte free Ca2+, yet K+ dilates parenchymal arterioles. It remains unclear whether fluctuations in external K+, within the low to moderate range, controls arteriole diameter through an astrocyte Ca2+ dependent mechanism. Using relative and quantitative two-photon fluorescence Ca2+ imaging in acute brain slices of the somatosensory cortex from Sprague Dawley rats, we found that elevations in external K+ from 2.5 mM to 3.5 or 5.0 mM decreased astrocyte free Ca2+ and caused arteriole dilation. The phenomenon relied on external Ca2+, Cl-, and bicarbonate, as well as, unexpectedly, the potassium chloride cotransporter (KCC). These data highlight novel aspects of K+-astrocyte dynamics that involve the subtle regulation of free astrocyte Ca2+ via Cl- and bicarbonate fluxes with corresponding changes to arteriole tone.
