description: A 448-year teak chronology from northwestern Thailand is used to assess past changes in the strength of the summer monsoon. The chronology is based on 30 living trees that extend from 1604 to 2005, and a 47-stump chronology that spans from 1558 to 1903. We used methods of cross dating and chronology building that address problems specifically found in teak. The result is a robust chronology with strong signal strength back to 1600 ad, and with variability retained at the multi-decadal scale. Variability in annual growth in teak from this area is dependent on rainfall and soil moisture availability at both the beginning and end of the monsoon season as confirmed by comparisons with temperature, rainfall and PDSI data. These correlation analyses confirm that our record is a proxy for summer monsoon strength and/or duration, and highlight the importance of soil moisture availability in the seasons of transition. The chronology reveals two prominent periods of decadal-scale drought in the early and mid 1700s that correspond to persistently warm sea surface temperature anomalies in the tropical Pacific as derived from Galapagos Island coral records. Speleothem data from central India also indicate protracted periods of drought for the 1700s. While these broad-scale eighteenth-century persistent droughts may be related to protracted El Niño-like conditions in the tropical Pacific, regional climate forcing over the Indian Ocean and western Pacific sectors appears to be a strong contributor as well. Spectral analyses reveal power in the ENSO range of variability from 2.2 to 4 years, and at the multi-decadal scale at 48.5 years.
title: Algorithmic Information Theory Applications in Bright Field Microscopy and Epithelial Pattern Formation
Creators: name: Mohamadlou, Hamid
Publisher: name: Utah State University
Year: 2015

description: Algorithmic Information Theory (AIT), also known as Kolmogorov complexity, is a quantitative approach to defining information. AIT is mainly used to measure the amount of information present in the observations of a given phenomenon. In this dissertation we explore the applications of AIT in two case studies. The first examines bright field cell image segmentation and the second examines the information complexity of multicellular patterns. In the first study we demonstrate that our proposed AIT-based algorithm provides an accurate and robust bright field cell segmentation. Cell segmentation is the process of detecting cells in microscopy images, which is usually a challenging task for bright field microscopy due to the low contrast of the images. In the second study, which is the primary contribution of this dissertation, we employ an AIT-based algorithm to quantify the complexity of information content that arises during the development of multicellular organisms. We simulate multicellular organism development by coupling the Gene Regulatory Networks (GRN) within an epithelial field. Our results show that the configuration of GRNs influences the information complexity in the resultant multicellular patterns.

description: We consider the small deformation of the point-like Wilson loop in the 3-dimensional $\mathcal{N}=6$ superconformal Chern-Simons theory. By Taylor expansion of the point-like Wilson loop in powers of the loop variables, we obtain the BPS operators that correspond to the excited string states of the dual IIA string theory on the pp wave background. The BPS conditions of the Wilson loop constrain both the loop variables and the forms of the operators obtained in the Taylor expansion.

description: In counting experiments, one can set an upper limit on the rate of a Poisson process based on a count of the number of events observed due to the process. In some experiments, one makes several counts of the number of events, using different instruments, different event detection algorithms, or observations over multiple time intervals. We demonstrate how to generalize the classical frequentist upper limit calculation to the case where multiple counts of events are made over one or more time intervals using several (not necessarily independent) procedures. We show how different choices of the rank ordering of possible outcomes in the space of counts correspond to applying different levels of significance to the various measurements. We propose an ordering that is matched to the sensitivity of the different measurement procedures and show that in typical cases it gives stronger upper limits than other choices. As an example, we show how this method can be applied to searches for gravitational-wave bursts, where multiple burst-detection algorithms analyse the same data set, and demonstrate how a single combined upper limit can be set on the gravitational-wave burst rate.

title: Using Video Prompting on an iPod Touch to Teach Multiple-Step Recipes to Transition-Age Students With Moderate to Severe Cognitive Disabilities
Creators: name: Mourra, Kjerstin
Publisher: name: Utah State University
Year: 2015

description: This study investigated effects of video prompting using an iPod Touch to teach recipe-following to four 16-19 year-old youth with intellectual disability and autism in a transition classroom. Target behaviors involved correctly following three multi-step recipes: microwave dinner, brownies, and gelatin. A multiple-probe design across recipes was replicated across participants. After low levels of responding in baseline probes, researchers presented participants with an iPod Touch showing each step of the task using video and with audio narration. Following the video prompting phase, maintenance and home-based generalization probes were conducted. The intervention increased recipe-following performance for all participants. Performance maintained and generalized to youths’ home kitchens. Results are discussed in regards to using video demonstrations in a sequence of prompts.
title: Young Widows' Grief: A Descriptive Study of Personal and Contextual Factors Associated with Conjugal Loss
Creators: name: Dunn, C. Ryan
Publisher: name: Utah State University
Year: 2015

description: Grief is a natural condition resulting from human loss. It is also a variable process through which aggrieved persons pass and by which a variety of personal and contextual factors can impact the both the breadth and depth. Concordantly, grief resulting from the loss of a spouse is one of the most difficult psychological and social issues through which someone can pass. Among the variety of factors associated with conjugal grief, loss that occurs outside the normative pattern of life events has received little attention. This study of 232 young widows between the ages of 18 and 55 was conducted to ascertain the factors that were associated with off-time conjugal grief. To do this, the present study utilized data from an online survey that was disseminated largely via social network sites and grief support groups across the United States. Framed in Erikson’s lifespan theory of psychosocial development and utilizing the dual process model of coping with bereavement, this study included an assessment of the impact of quality of life, coping orientation, adulthood psychosocial balance, and sociodemographic factors on grief in young widowhood. Using correlational and regression analyses, many of these variables were individually associated with young widows’ levels of grief. Through additional multiple regression analyses conducted in pursuit of a more parsimonious model, when accounting for the other variables several predictors were no longer found to provide unique contribution to participant grief. In the final model, when simultaneously adjusting for all study variables retained from earlier analyses, higher levels of loss-oriented coping were found to be associated with higher levels of grief. Additionally, higher levels of intimacy balance and participants’ longer length of relationship with their deceased spouse were both associated with lower levels of grief. These findings highlight similarities found in past research regarding conjugal loss, including loss at younger ages, grief work, and the buffering effect of intimacy balance on levels of grief. Contrary to past research on grief, the relative importance of factors such as identity balance, religiosity, and social support were limited in their net influence on grief in young widowhood. These findings can inform future research and intervention regarding the context and impact of conjugal loss that occurs at younger ages.

description: We have initiated a survey using the newly commissioned X-shooter spectrograph to target candidate relatively metal-rich damped Lyman-alpha absorbers (DLAs). The spectral coverage of X-shooter allows us to search for not only Lyman-alpha emission, but also rest-frame optical emission lines. We have chosen DLAs where the strongest rest-frame optical lines ([OII], [OIII], Hbeta and Halpha) fall in the NIR atmospheric transmission bands. In this first paper resulting from the survey, we report on the discovery of the galaxy counterpart of the z_abs = 2.354 DLA towards the z=2.926 quasar Q2222$-0946. This DLA is amongst the most metal-rich z>2 DLAs studied so far at comparable redshifts and there is evidence for substantial depletion of refractory elements onto dust grains. We measure metallicities from ZnII, SiII, NiII, MnII and FeII of -0.46+/-0.07, -0.51+/-0.06, -0.85+/-0.06, -1.23+/-0.06, and -0.99+/-0.06, respectively. The galaxy is detected in the Lyman-alpha, [OIII] lambda4959,5007 Halpha emission lines at an impact parameter of about 0.8 arcsec (6 kpc at z_abs = 2.354). We infer a star-formation rate of 10 M_sun yr^-1, which is a lower limit due to the possibility of slit-loss. Compared to the recently determined Halpha luminosity function for z=2.2 galaxies the DLA-galaxy counterpart has a luminosity of L~0.1L^*_Halpha. The emission-line ratios are 4.0 (Lyalpha/Halpha) and 1.2 ([OIII]/Halpha). The Lyalpha line shows clear evidence for resonant scattering effects, namely an asymmetric, redshifted (relative to the systemic redshift) component and a much weaker blueshifted component. The fact that the blueshifted component is relatively weak indicates the presence of a galactic wind. The properties of the galaxy counterpart of this DLA is consistent with the prediction that metal-rich DLAs are associated with the most luminous of the DLA-galaxy counterparts.

description: Graphene active sensors have demonstrated promising capabilities for the detection of electrophysiological signals in the brain. Their functional properties, together with their flexibility as well as their expected stability and biocompatibility have raised them as a promising building block for large-scale sensing neural interfaces. However, in order to provide reliable tools for neuroscience and biomedical engineering applications, the maturity of this technology must be thoroughly studied. Here, we evaluate the performance of 64-channel graphene sensor arrays in terms of homogeneity, sensitivity and stability using a wireless, quasi-commercial headstage and demonstrate the biocompatibility of epicortical graphene chronic implants. Furthermore, to illustrate the potential of the technology to detect cortical signals from infra-slow to high-gamma frequency bands, we perform proof-of-concept long-term wireless recording in a freely behaving rodent. Our work demonstrates the maturity of the graphene-based technology, which represents a promising candidate for chronic, wide frequency band neural sensing interfaces.

description: We study the Kondo lattice model of band electrons coupled to classical spins, in three dimensions, using a combination of variational calculation and Monte Carlo. We use the weak coupling `RKKY' window and the strong coupling regime as benchmarks, but focus on the physically relevant intermediate coupling regime. Even for modest electron-spin coupling the phase boundaries move away from the RKKY results, the non interacting Fermi surface no longer dictates magnetic order, and weak coupling `spiral' phases give way to collinear order. We use these results to revisit the classic problem of 4f magnetism and demonstrate how both electronic structure and coupling effects beyond RKKY control the magnetism in these materials.

description: For classical Hamiltonian N-body systems with mildly regular pair interaction potential it is shown that when N tends to infinity in a fixed bounded domain, with energy E scaling quadratically in N proportional to e, then Boltzmann's ergodic ensemble entropy S(N,E) has the asymptotic expansion S(N,E) = - N log N + s(e) N + o(N); here, the N log N term is combinatorial in origin and independent of the rescaled Hamiltonian while s(e) is the system-specific Boltzmann entropy per particle, i.e. -s(e) is the minimum of Boltzmann's H-function for a perfect gas of "energy" e subjected to a combination of externally and self-generated fields. It is also shown that any limit point of the n-point marginal ensemble measures is a linear convex superposition of n-fold products of the H-function-minimizing one-point functions. The proofs are direct, in the sense that (a) the map E to S(E) is studied rather than its inverse S to E(S); (b) no regularization of the microcanonical measure Dirac(E-H) is invoked, and (c) no detour via the canonical ensemble. The proofs hold irrespective of whether microcanonical and canonical ensembles are equivalent or not.

description: Gianni Toti (Rome 1924-2007) was a prolific Italian poet, journalist and writer. In the early 1980s, he began to compose poems using electronic languages thanks to a department of the Italian public Television, “Rai - Ricerca e Sperimentazione Programmi”. He called himself “poetronico” , and he’s still known as one of the most representative authors of international video art. Focusing on his first Video-poem − entitled Per una videopoesia. Concertesto e improvvideazione per mixer, memoria di quadro e oscillo-spettro-vector-scopio (1980) − the essay tries to re-build the original development of Toti’s approach to electronic arts, using materials from his own archive (preserved by La Casa Totiana-Poetronicart) and the tracks left in his own previous publications; for example, through “Carte Segrete”, the review he co-directed from 1967.

title: Altitudinal Variability of Quiet-time Plasma Drifts in the Equatorial Ionosphere
Creators: name: Hui, Debrup
Publisher: name: Utah State University
Year: 2015

description: The plasma drifts or electric fields and their structures in the ionosphere affect the accuracy of the present-day space-based systems. For the first time, we have used ionospheric plasma drift data from Jicamarca radar measurements to study the climatology of altitudinal variations of vertical and zonal plasma drifts in low latitudes during daytime. We used data from 1998 to 2014 to derive these climatological values in bimonthly bins from 150 km to 600 km. For the vertical plasma drifts, we observed the drifts increasing with altitudes in the morning and slowly changing to drifts decreasing with altitude in the afternoon hours. The drifts change mostly linearly from E- to F-region altitudes except in the morning hours of May-June when the gradients are very small. The zonal drifts show a highly nonlinear increase in the westward drifts at the lower altitudes and then increase slowly at the higher altitudes. We see a break in the slopes at lower altitudes during the morning hours of March-April and May-June. The E-region zonal drifts, unlike vertical drifts, show a very large variability compared to F-region drifts. We also explored the altitudinal profiles of vertical drifts during late afternoon and evening hours when the electrodynamic properties in the ionosphere change rapidly. For the first time using drifts up to 2000 km, we have shown the drifts increase and decrease below and above the F-region peak before becoming height independent. These structures arise to satisfy the curl-free condition of electric fields in low latitudes. The altitudinal gradients of vertical drifts are balanced by a time derivative of the zonal drifts to satisfy the curl-free condition of electric fields. We have shown how these structures evolve with local time around the dusk sector and change with solar flux. During solar minimum, the peak region can go well below 200 km. The present-day electric field models do not incorporate these gradients, particularly in the evening sectors when they change very rapidly. Very often their results do not match with the observations. Including these gradients along with proper magnetic field models will improve the model results and accuracy of our navigation, communication, and positioning systems.
Facendo saltare le parole. Sulle ‘scritture vocali’ di Gabriella Bartolomei

description: This essay aims to investigate the original experience of the performative nexus between words / images and vocalism / music, which characterizes the work of the actress Gabriella Bartolomei. Her performances are striking evidence of the diffusion of Neo-Avant-Garde artistic experiments, even outside a clear belonging to specific cultural movement. Indeed, Bartolomei performs texts of other authors through a system of iconic rewriting (‘scritture vocali’), which is very similar to the experiences of visual poetry because she uses the same techniques of drawing, painting, and collages. In both cases, the iconic arrangement of the graphic and alphanumeric signs has a hermeneutical, mnemonic, and creative purpose. Only after having iconically translated the text to be interpreted is Bartolomei able to make a vocal performance.

description: Some of the first tree-ring chronologies from mainland Southeast Asia have been developed from Thailand, and a significant link between climate and tree growth has been suggested. Four chronologies from two species of pine (Pinus kesiya Royle ex Gordon and Pinus merkusii Jungh. ' de Vriese) from northeastern, lower northern and northwestern Thailand have been constructed: three from P. kesiya and one from P. merkusii. A second P. merkusii chronology is being developed from samples from northwestern Thailand. Preliminary climate modelling demonstrates significant relationships for tree growth with both temperature and precipitation for both species. A significant, direct relationship is revealed with temperature at the beginning of the wet season for Pinus merkusii from Thung Salaeng Luang National Park, along with an inverse relationship with precipitation for the same period. It is also suggested that the month of November (the transitional month from wet to dry season) during the year of growth is most important for Pinus kesiya from Nam Nao National Park, based on significant, direct relationships with both temperature and precipitation. The dendrochronological potential of another species, the long-lived Podocarpus neriifolius, is also discussed.
Electrostatic proton cyclotron harmonic waves observed with the Alouette II satellite

Publisher: name: University of British Columbia
Year: 2011

description: An ELF noise band observed by the Alouette II satellite has been studied. A digital power spectrum program was set up in order to investigate in detail the noise band spectra. Primary results from this analysis are that: a) for altitudes 500-3000 Km. and all geomagnetic latitudes, sharp lower cutoffs of the noise band occur within ~30Hz of the calculated gyrofrequency, b) upper cutoffs to the noise band occur frequently near harmonics of the gyrofrequency, and c) the noise appears to be Doppler shifted when the angle between the velocity vector of the satellite and the geomagnetic field is near 90°. The occurrence pattern of the noise band has been investigated using available Rayspan analyzed data for epoch 1966. This analysis indicated a pronounced daytime maximum of occurrence. It is shown that almost all aspects of the noise band may be interpreted in terms of the hypothesis of ambient electrostatic proton cyclotron harmonic waves in the ionosphere, and the concomitant accessibility conditions in the spatially varying geomagnetic field.

description: The gut microbiome plays a quintessential role in the development and maintenance of the neuro-immune system throughout lifespan. Changes in microbial composition during critical periods of development—such as puberty—are associated with long-term disruptions in brain function and neuro-immune responsivity. However, the mechanisms underlying the effect of microbial dysbiosis on the pubertal neuro-immune response has yet to be elucidated. Therefore, the current thesis was designed to investigate the effect of changes in gut microbial composition (through antibiotic and probiotic exposure) in pubertal male and female mice on acute lipopolysaccharide (LPS)-induced immune response. Male and female CD1 mice were treated with one week of antibiotic treatment (mixed antibiotics or water) and probiotic treatment (lacidofil, probio’stick, or placebo) at five weeks of age. At six weeks of age (pubertal stress-sensitive period), the mice received a single injection of LPS or saline. Sickness behaviours were assessed and mice were euthanized at eight hours’ post-injection. Brain, blood, and intestinal measures were collected. The results indicated that the antibiotic treatment reduced sickness behaviours, increased LPS-induced plasma cytokine concentrations, and LPS-induced hippocampal pro-inflammatory markers in a sexually dimorphic manner. Probiotics reduced LPS-induced plasma cytokine concentrations and hippocampal pro-inflammatory markers in a sexually dimorphic manner. Lacidofil supplementation mitigated antibiotic-induced plasma cytokine concentrations and sickness behaviours. These findings suggest that the microbiome is an important modulator of the pro-inflammatory immune response during puberty. These results also have implications for the neuro-immune mechanisms with which gut dysfunctions influence brain function and behaviours.
title: Site-Based and Nonsite Archaeological Survey: A Comparison of Two Survey Methods in the City of Rocks, Idaho
Creators: name: McDonald, Patrick Reed
Publisher: name: Utah State University
Year: 2015

description: Pedestrian based archaeological survey is commonly used throughout the western United States to locate, identify, record, and interpret archaeological sites. While procedures, such as transect spacing, transect orientation, data collection, artifact documentation, and site criteria may vary, most survey methods share a common goal: to locate and define the boundaries of archaeological sites. Other researchers question the traditional site-based survey method. Critics suggest that site-based surveys may fail to adequately detect and document artifacts outside of site boundaries (Dunnell and Dancey 1983; Wandsnider and Camilli 1992). Site-based methods may not discern archaeological signatures of past cultures that occurred on the scale of landscapes rather than discrete sites (Ebert 1992; Robins 1998)
In response, siteless approaches have been developed to test and address perceived shortcomings of site-based survey methods. The siteless survey utilizes artifacts as the basis for studying the relationships between clustered and non-clustered materials. This thesis examines traditional site-based survey vs. siteless survey within a study area in southern Idaho. Moreover, the study investigates the utility of the nonsite approach to identify spatial distributions, associations, and patterning in cultural materials on the surface of the analysis area. The results of the survey, data management and analyses evaluate if artifacts are randomly distributed or aggregated.
Survey results compare the surveys’ effectiveness in detecting artifacts. In this comparison, the effects of artifact obtrusiveness/visibility are considered. Results of survey data are examined at different spatial scales to identify clusters and evaluate cluster attributes. Spatial patterning analyses use GIS software including the Getis Ord Gi* hot spot analysis tool and the buffer tool in ArcMap 10.2. Both GIS analyses successfully identified clustering. Finally, the results of analysis compare artifact cluster attributes identified by GIS analyses with site attributes. Siteless survey data and post-field, GIS analyses demonstrate the ability to offer information not available through traditional site-based survey. These results suggest that the siteless survey methods and analytic techniques employed in this study warrant further testing and evaluation.

description: The ATLAS Pixel detector is a high-resolution, low-noise silicon-based device designed to provide tracking and vertexing information within a distance of 12 cm from the LHC beam axis. It consists of approximately 80 million pixel channels with radiation-hard front-end electronics connected through optical fibers to a custom-controlled DAQ system away from the detector. Following the successful installation of the detector in June 2007, an intense commissioning period was conducted in the year 2008 and more than 400,000 cosmic-ray tracks were recorded in conjunction with other ATLAS sub-detectors. By the end of the year, 96% of the detector was tuned, calibrated, and taking data at 99.8% tracking hit efficiency and with noise occupancy at the 10^-10 level. We present here the results of the commissioning, calibration, and data-taking as well as the outlook for future performance with LHC collision-based data.

title: Understanding Westerners' Relationship with Public Lands and Federal Land Managers Through Attachment to Public Lands
Creators: name: Sisneros, Chris
Publisher: name: Utah State University
Year: 2015

description: The vast swathes of public lands in the western U.S. have long been connected with both the culture and daily lives of the people that live near them. The purpose of this study is to understand the relationship that individuals have with public lands and how that relationship relates to their opinions about the federal agencies (specifically the Forest Service and Bureau of Land Management) that oversee those public lands. This is done through the use of the effective bond attachment to public lands, which is the degree to which individuals feel connected to public lands through both the opportunities they provide to enjoy their desired lifestyle, functional connections, and the ways in which personal identity is tied to those lands, emotional connections. Assessing this bond is done through analysis and interpretation of selected data from the 2007 Public Lands and Utah Communities survey, which looked at a variety of connections Utah residents have to the state’s many public lands. This study utilizes a novel statistical method known as the “inverted-R analysis,” which groups respondents based on answers to a variety of attitudinal measures, to develop three distinct typologies of attachment to public lands. Analysis of differences between the groups of respondents that expressed different types of attachment revealed no correlation between attachment to public lands and opinions about land managers. All respondents expressed generally negative sentiment towards both Forest Service and Bureau of Land Management land managers. However, respondents who expressed a stronger attachment to public lands also demonstrated higher levels of interaction with public lands. Additionally, functional and emotional connections to public lands were shown to operate as two separate parts of attachment to public lands. This reinforces the modeling of the conceptualization attachment to public lands after the related concept, place attachment. This study demonstrated both the strong connections individuals in Utah have with public lands and the strong opinions held about the agencies that manage those lands.

description: Since Kentucky’s initial rumble strip designs were adopted, there has been additional research and experimentation in other states with alternative designs as a response to complaints from the public about noise pollution caused by rumble strips. The new research indicates that other rumble strip designs might provide increased interior noise/vibration with decreased exterior noise. Application of these alternative designs in Kentucky could result in improved rumble performance, reduced damage to new pavement, decreased noise pollution, installation on roadways with lower speed limits, and allow reinstallation of rumbles on thin overlays/microsurfacing.

The research team reviewed national and state guidelines for conventional and alternative rumble strip designs and compiled a synthesis of current rumble strip practices. A series of site visits to rumble strip installations across the state revealed many findings about Kentucky’s current rumble strip practices.

This research provides recommendations for conventional, sinusoidal, and shallow rumble strips as well as for rumble strip maintenance, rumble strips on thin overlays, and the use of edgeline and centerline rumble strips.

description: This work attempts to predict the long-term outcome of total hip arthroplasty based on available patient-specific information and possible installation positions of the prosthesis. For this purpose, a holistic modeling approach for the numerical simulation of osseointegration and long-term stability of endoprostheses, including possible prosthesis positions, is developed. In addition, new, efficient, and reliable methods for the numerical description of adaptive bone remodeling and osseointegration are proposed: The adaptive bone remodeling is described as a geometric-linear, material-nonlinear finite element model, following thermodynamically consistent material modeling guidelines. The resulting constitutive equations are expanded to describe osseointegration and transferred into a contact interface between bone and prosthesis. Finally, the results are projected to an imaging format that is easier to interpret for medical professionals, using a newly developed simulation for X-ray images. The inclusion of possible prosthesis positions spans an infinite-dimensional event space. Therefore, the model is reduced to a finite-dimensional surrogate model sampled with an adaptive sparse-grid collocation method. Without clinical validation, reliable statements cannot be made, and therefore the numerical examples given in this thesis can be regarded as proof of correct implementation and feasibility studies. This dissertation thus provides an answer to how much computational effort is required to provide a real digital decision aid in orthopedic surgery.
Unambiguous quantization from the maximum classical correspondence that is self-consistent: the slightly stronger canonical commutation rule Dirac missed

description: Dirac's identification of the quantum analog of the Poisson bracket with the commutator is reviewed, as is the threat of self-inconsistent overdetermination of the quantization of classical dynamical variables which drove him to restrict the assumption of correspondence between quantum and classical Poisson brackets to embrace only the Cartesian components of the phase space vector. Dirac's canonical commutation rule fails to determine the order of noncommuting factors within quantized classical dynamical variables, but does imply the quantum/classical correspondence of Poisson brackets between any linear function of phase space and the sum of an arbitrary function of only configuration space with one of only momentum space. Since every linear function of phase space is itself such a sum, it is worth checking whether the assumption of quantum/classical correspondence of Poisson brackets for all such sums is still self-consistent. Not only is that so, but this slightly stronger canonical commutation rule also unambiguously determines the order of noncommuting factors within quantized dynamical variables in accord with the 1925 Born-Jordan quantization surmise, thus replicating the results of the Hamiltonian path integral, a fact first realized by E. H. Kerner. Born-Jordan quantization validates the generalized Ehrenfest theorem, but has no inverse, which disallows the disturbing features of the poorly physically motivated invertible Weyl quantization, i.e., its unique deterministic classical "shadow world" which can manifest negative densities in phase space.

Earthquake swarm on the Queen Charlotte Islands fracture zone
Creators: name: Wetmiller, Robert Joseph
Publisher: name: University of British Columbia

description: An earthquake swarm occurring on a segment of the ocean rise system in the northeast Pacific Ocean is considered. The data are in the form of standard seismograph records from the western portion of British Columbia, covering the period August 27 to September 1, 1967. The study follows two lines of investigation. Five seismograph stations in western British Columbia are considered as an array and 19 of the larger magnitude events located with respect to this array. The closest station to the swarm is on the northern end of Vancouver Island about 180 km from the source area. This station recorded 217 distinct arrivals in the 5-day period. Statistical properties of the swarm plus the magnitude-frequency relationship can thus be estimated. The Pn and Sn arrivals in western British Columbia show the following time-distance relationships: T[subscript Pn] = (5.51±0.38) + Δ/(7.69±0.03) T[subscript Sn] = (10.16±1.25) + Δ/(4.45±0.03) These travel times are consistent with a crust on Vancouver Island greater than 50 km thick. The epicenters for events in the swarm are associated with two distinct tectonic features in the northeast Pacific Ocean - the Explorer Trench and the Queen Charlotte Island Fracture Zone. The events in the swarm show a non-random distribution in time and the polarity of the first arrival varies with station and with event. These facts suggest a generating process involving strain release by movement on a fault or faults coupled with some sort of triggering mechanism. The magnitude-frequency relationship is determined as Log₁₀N = (4.07±0.50) - (1.10±0.20)M[subscript L] for 2.0 < M[subscript L] < 4.0. The value for the slope (-1.10) is characteristic of earthquake swarms generated as a result of volcanic activity. The apparent paradox concerning the source mechanism is reconciled in the idea of "The New Global Tectonics" that extension across ridge crests (involving generation of new crustal material by diapiric intrusions) and transform faulting of the off-setting fracture zones will occur together.

description: Inelastic dark matter reconciles the DAMA anomaly with other null direct detection experiments and points to a non-minimal structure in the dark matter sector. In addition to the dominant inelastic interaction, dark matter scattering may have a subdominant elastic component. If these elastic interactions are suppressed at low momentum transfer, they will have similar nuclear recoil spectra to inelastic scattering events. While upcoming direct detection experiments will see strong signals from such models, they may not be able to unambiguously determine the presence of the subdominant elastic scattering from the recoil spectra alone. We show that directional detection experiments can separate elastic and inelastic scattering events and discover the underlying dynamics of dark matter models.

description: Autonomic management can improve the QoS provided by parallel/ distributed applications. Within the CoreGRID Component Model, the autonomic management is tailored to the automatic - monitoring-driven - alteration of the component assembly and, therefore, is defined as the effect of (distributed) management code. This work yields a semantics based on hypergraph rewriting suitable to model the dynamic evolution and non-functional aspects of Service Oriented Architectures and component-based autonomic applications. In this regard, our main goal is to provide a formal description of adaptation operations that are typically only informally specified. We contend that our approach makes easier to raise the level of abstraction of management code in autonomic and adaptive applications.

description: Utah juniper was a foundational species for the discipline of dendrochronology, having been used in the early 20th Century investigations of Mesa Verde, but has been largely ignored by dendrochronologists since. Here we present dendrochronological investigations of Utah juniper core and cross-sectional samples from four sites in northern Utah. We demonstrate that, contrary to the general opinion among many dendrochronologists, Utah juniper exhibits excellent crossdating that is reflective of its sensitivity to climate - a desirable characteristic for dendroclimate reconstruction. Across all four sites the dominant signal for annual ring-width increment occurred during the growing season and was positive for precipitation and negative for temperature. This corroborates ecophysiological studies that highlight Utah juniper’s aggressive water-use behavior and desiccation tolerance that together enable survival at extremely negative soil water potentials. This behavior differs from co-occurring Pinus spp. (i.e. P. edulis and P. monophylla) that avoid cavitation at the cost of carbon starvation. We determine that the annual radial increment of Utah juniper rings is particularly responsive to soil moisture availability, and is in fact a useful proxy for hydroclimatic variables such as precipitation, drought, and streamflow. Its geographic distribution spans a large swath of the Interior West, including areas where other more commonly sought-after species for dendrochronology do not occur, and ought to be considered crucial for complementing the rich network of tree-ring chronologies in the western U.S.
title: Identification of DNA Markers in Triticum aestivum-Aegilops caudata Additions Lines by Randomly Amplified Polymorphic DNA (RAPD) Technology
Creators: name: Wei, Ling

description: The objective of this study was to identify DNA markers for each of six added C-genome chromosomes in Triticum aestivum L. cv. 'Alceso'-Aegilops caudata L. addition lines using the randomly amplified polymorphic DNA (RAPD) technique. DNA from Ae. caudata, T. aestivum, amphiploid of T. aestivum X Ae. caudata, and six disomic addition lines of wheat having a pair of Ae. caudata chromosomes was used as the template for the amplification of RAPD markers with a total of 58 random 10-mer oligonucleotide primers. Two primers, OPC-08 and OPJ-16, produced one intense band each from the amphiploid of T. aestivum X Ae. caudata and Ae. caudata, which was absent in all six addition lines. Each of these two primers produced a chromosome marker that could be tentatively located to the chromosome CA of Ae. caudata. OPJ-02, OPD-12, OPD-02, OPJ-12, OPD-20, and OPJ-14 produced a marker each for CB, CC, CD, CE, CF, and CG, respectively. OPJ-09 produced C-genome chromosome-specific RAPD markers. Also, OPC-05 and OPJ-19 produced RAPDs from both wheat and Ae. caudata genomes.
