Accounting for Critical Attributes and Uncertainty in Flow-Ecology Relationships
Creators: name: Morgan, Elizabeth Decker
Publisher: name: Utah State University

description: Environmental flows are used to maintain streamflow for aquatic species in rivers while also sustaining human water requirements. While there are many approaches to develop environmental flows, they all rely on a strong conceptual understanding of flow-ecology relationships, which are often uncertain. Uncertainty in flow-ecology relationships can stem from using limited data to develop or test relationships or an incomplete understanding of the attributes inherent to each relationship, such as climate and land conditions. Accounting for these attributes and uncertainty in flow-ecology relationships is critical given mounting interest to develop and implement environmental flows at large scales, often with limited information. Using the South Fork Eel River watershed in northern California USA as a case study, I explored attributes and uncertainty in flow-ecology relationships through a targeted review of academic journal articles and Bayesian Network modeling. I found that few relationships describe explicit links between the flow regime and species or cover the full range of climate and land conditions present in the watershed. These gaps informed several scenarios within a Bayesian Network model—represented as different sets of probabilities—which show that model results can differ by up to 50% depending on the uncertainty scenario. This study informs future field monitoring efforts to develop flow-ecology relationships and promotes effective translation and modeling of existing flow-ecology relationships and their uncertainties.

description: We study the statistics of optical data transmission in a noisy nonlinear fiber channel with a weak dispersion management and zero average dispersion. Applying path integral methods we have found exactly the probability density functions of channel output both for a non-linear noisy channel and for a linear channel with additive and multiplicative noise. We have obtained analytically a lower bound estimate for the Shannon capacity of considered nonlinear fiber channel.

description: The tetragonal phase of chromium (III) oxide, although unstable in the bulk, can be synthesized in epitaxial heterostructures. The theoretical investigation by density functional theory predicts an antiferromagnetic ground state for this compound. We demonstrate experimentally antiferromagnetism up to 40 K in ultrathin films of t-Cr2O3 by electrical measurements exploiting interface effect within a neighboring ultrathin Pt layer. We show that magnetotransport in Pt is affected by both spin-Hall magnetoresistance and magnetic proximity effect while we exclude any role of magnetism for the low-temperature resistance anomaly observed in Pt.

description: We put stringent constraints for the first time on the dust properties in the circumburst medium of a gamma-ray burst (GRB) afterglow. This is based on the optical spectrum of GRB 020813 (z=1.255), obtained with Keck I LRIS 4.65 h after the burst. From the absorption lines in the spectrum, we derive very high column densities for six heavy elements with different refractory properties. The relative abundances resemble the dust depletion patterns in the Milky Way, from which we infer a visual extinction of A_V=0.4 and A_V>0.3 at 95% confidence level. However, the high columns of metals and dust contrast with an observed UV continuum spectrum that is remarkably close to a power law of the form F_nu \propto nu^{-0.9}, with no sign of curvature, or a 2200 A extinction feature, suggesting low reddening. The Milky Way or Magellanic Cloud reddenings are possible only for very low visual extinctions (A_V<0.08 or A_V<0.2, respectively at 95% confidence), inconsistent with the A_V values inferred from the depletion analysis. If we assume a GRB intrinsic spectrum and an extinction law of the forms F_lambda^i = F_V (5500/lambda)^alpha and A_lambda= A_V (5500/lambda)^gamma, we obtain (for A_V=0.4) the constraints from continuum spectrum: gamma<0.85 and alpha<1.72.

description: We present the results of an investigation on the main structural properties derived from VRI and Halpha surface photometry of galaxies hosting nuclear emission-line regions (including Seyfert 1, Seyfert 2, LINER and starburst galaxies) as compared with normal galaxies. Our original sample comprises 22 active galaxies, 4 starbursts and 1 normal galaxy and has been extended with several samples obtained from the literature. Bulge and disc parameters, along with B/D relation, have been derived applying an iterative procedure. The resulting parameters have been combined with additional data in order to reach a statistically significant sample. We find some differences in the bulge distribution across the different nuclear types that could imply familes of bulges with different physical properties. Bulge and disc characteristic colours have been defined and derived for our sample and compared with a control sample of early type objects. The results suggest that bulge and disc stellar populations are comparable in normal and active galaxies.

description: Heatwaves (HWs) pose a severe threat to human and ecological systems. Here we assess the projected changes in heatwaves over Latin America using bias corrected high-resolution regional climate simulations under two Representative Concentration Pathway scenarios (RCPs). Heatwaves are projected to be more frequent, long-lasting, and intense in the mid-century under both RCP2.6 and RCP8.5 scenarios, with severe increases under the RCP8.5 scenario. Even under the low emissions scenario of RCP2.6, the frequency of heatwaves doubles over most of the region. A three- to tenfold rise in population exposure to heatwave days is projected over Central and South America, with climate change playing a dominant role in driving these changes. Results show that following the low emission pathway would reduce 57% and 50% of heatwave exposure for Central and South American regions respectively, highlighting the need to control anthropogenic emissions and implement sustainable practices.

description: Το πρωτοπαθές λέμφωμα του μεσοθωρακίου από μεγάλα Β-κύτταρα (PMBL), και το κλασικό λέμφωμα Hodgkin του τύπου της οζώδους σκλήρυνσης (NSCHL), αποτελούν δύο οντότητες που αν και ανήκουν σε διαφορετικές οικογένειες, έχουν κοινό μοριακό υπόβαθρο και κοινή κλινική εικόνα, ενώ ενίοτε παρουσιάζουν και αλληλοεπικαλυπτόμενα ιστολογικά χαρακτηριστικά. Δεδομένης της εξάρτησης που παρουσιάζουν τα λεμφώματα από τα κύτταρα του μικροπεριβάλλοντος τους, ελέγξαμε αν οι ανωτέρω ομοιότητες καθρεπτίζονται και στη κυτταρική σύσταση αυτού. Για αυτό τον σκοπό, χρησιμοποιήθηκαν είκοσι-τέσσερα περιστατικά από το αρχείο του Εργαστηρίου μας (δώδεκα PMBL και δώδεκα NSCHL) ασθενών με ανάπτυξη μάζας στο μεσοθωράκιο. Τα περιστατικά επανεξετάστηκαν για την επιβεβαίωση της διάγνωσης τους και διερευνήθηκαν για τα επίπεδα διήθησης από CD4+ T κύτταρα, CD8+ T κύτταρα, FOXP3+ κύτταρα, ηωσινόφιλα και μαστοκύτταρα. Τα αποτελέσματα ανέδειξαν υψηλότερα επίπεδα διήθησης του NSCHL από όλα τα κύτταρα εξαιρουμένων των CD8+ Τ κυττάρων. Επίσης, σε δύο περιστατικά PMBL αναδείχθηκε θετικότητα των νεοπλασματικών κυττάρων στο αντίσωμα FOXP3+. Συμπερασματικά, τα αποτελέσματα μας ανέδειξαν διαφορές στη σύσταση του μικροπεριβάλλοντος των δύο οντοτήτων με διαφοροδιαγνωστική αξία, ενώ οι χαμηλοί αριθμοί FOXP3+ στο PMBL υποδεικνύουν διαφορετικούς μηχανισμούς επαγωγής της Τ κυτταρικής ανεργίας, που χαρακτηρίζει τη συγκεκριμένη οντότητα.
description: Primary mediastinal B-cell lymphoma (PMBL) and nodular sclerosis classical Hodgkin’s lymphoma (NSCHL) are two entities than even though belong in different families, share a common molecular background and a common clinical presentation, while occasionally present with overlapping histological features. Given the great dependence that lymphomas exhibit on the tumor microenvironment, we wanted to see how the aforementioned similarities affect the cellular composition of it. For this purpose, we used twenty-four cases (12 cases with PMBL and 12 with NSCHL) of previously untreated patients presenting with a mediastinal mass. All of the cases were reevaluated for the confirmation of the diagnosis and examined for the presence of CD4+ T cells, CD8+ T cells, FOXP3+ cells, eosinophils and mast cells. The results showed a greater infiltration of all of the above cells in NSCHL, except for the CD8+ T cells. Moreover, two PMBL cases had FOXP3+ neoplastic cells. Conclusively, our findings can be of use for the differential diagnosis of the two entities. Furthermore, since PMBL lacks FOXP3+ cells, we assume that the T-cell anergy is achieved via different mechanisms.
Trends in US Crop Yields & Water Use
Creators: name: Schumacher, Britta L.
Publisher: name: Utah State University
Year: 2021

description: Over half the land in the US is dedicated to agriculture, with the vast majority of all cropland cultivated in corn, wheat, or soybean. Despite continuing advances in agricultural technologies, and consistent yield growth over the twentieth century, research suggests that environmental change is already impacting agricultural yield and future changes are sure to exacerbate challenges to agricultural production. It follows that the future of US agriculture depends on the evolution of the changing climate, the relationship between crop yields and the environment, on-farm management and adaptations, the ecosystems that support agriculture, the political and economic incentives that shape what farmers grow and how they grow it, and the technology developed to improve yields. This study will focus on two pieces of the aforementioned agricultural puzzle—the relationship between crop yields and the environment, and water use management in irrigated agriculture. This study contributes to current literature by exploring trends in irrigated agriculture at the county-scale, and by examining the efficacy of Random Forest (RF) regression in predicting agricultural yield. Results from the second chapter, where we utilize exploratory mapping and data mining techniques to understand trends in irrigated agriculture in the Western US, are pending approval from the USDA-NASS and are not reported here. Alternatively, we build a practical guide to working with operator-level irrigation survey data. Results from the third chapter suggest that RF predicts US corn yields well and point to the importance of space and time in corn yield prediction, and the highly nonlinear response of corn yield to irrigation, climate, and agricultural diversity covariates. These results demonstrate the predictive capacity of RF regression to model complex corn yield responses to biophysical and landscape conditions and point to the power of building an ensemble of different models, each with their own strengths and weaknesses, to characterize and predict agricultural yield.

description: In order to compare the comparative advantage of japonica between China and Korea, the study analyzes the production cost. After comparing the cost and its structure, it is found that the production of Japonica in China has more comparative advantage obviously. But the increasing rate is much higher than that of Korea in recent 10 years. In the long term, the gap between two countries will become smaller, while the inferior advantage of Korea can't be changed during short-mid term. Some measures should be adopted to develop the competitiveness of japonica in Korea, such as, adjusting agricultural structure, enlarging the land scale and making quality differentiation.
Regionalized Models with Spatially Continuous Predictions at the Borders
Creators: name: Wagstaff, Jadon S.
Publisher: name: Utah State University
Year: 2021

description: Creating maps of continuous variables involves estimating values between measurement locations scattered throughout a geographic region. These maps often leverage observed similarities between geographically close measurements, but may also make predictions using other geographic information such as elevation. The relationship between the available geographic information and the variable of interest can vary with location, especially when mapping large areas like a continent. A simple way to account for the changing relationship is to divide the space into different sub-regions and model the relationship at each region. The naive implementation of this approach has the side effect of making sudden changes in predictions at the borders of each region. This thesis describes a novel regional border smoothing method that allows for the formation of a continuous map built with regional models. The method is implemented and available to the public through the open source R package remap. Improvements in model accuracy are demonstrated using a national scale and a state scale dataset.

description: Rare-earth (RE) based compounds and alloys are of great interest both for their fundamental physical properties and for applications. In order to tailor the required compounds for a specific task, one must be able to predict the energy level structure and transition intensities for any magnetic ion in any crystalline environment. The crystal-field (CF) analysis is one of the most powerful theoretical methods to deal with the physics of magnetic ions. In the present work, this technique is used to analyze peculiar physical properties of some materials employed in the production of new-generation solid-state laser and high-performance permanent magnets.

title: The transition from Calc-alkaline to Potassic Volcanism in the Aeolian Islands, Southern Italy
Creators: name: Ellam, Robert Mark
Publisher: name: The Open University
Year: 1987

description: The geochemical and petrological variations of a range of lavas from the Aeolian Islands volcanic arc, southern Italy are investigated and compared with potassic and ultra-potassic volcanism in the Roman region, and with subduction related basalts from throughout the world. Aeolian Islands lavas range from calc-alkaline basalts and andesites, typified by lavas from the island of Salina, to potassium rich shoshonites and tephrites found at Stromboli and Vulcano. Variations within individual lava series may be largely explained by fractional crystallisation, however the differences between the series are not due to this process and the various series are thought to originate from a range of parental magmas with quite different K2O content. Potassic lavas from Vulcano are characterised by incompatible element ratios typical of subduction related volcanism, and by relatively low 87Sr/86Sr ratios (0.70432-0.70494) similar to those of calc-alkaline lavas from Salina (0.70411-0.70466). In contrast at Stromboli, potassic lavas have relatively high Nb and Ta contents and elevated 87Sr/86Sr (0.7050-0.7075) A three component mixing model is proposed to explain the geochemistry of the Aeolian Islands lavas, this involves mantle wedge, a subduction related component thought to originate by dehydration of the subducting lithosphere, and a component derived from subducted sedimentary material. In addition some heterogeneity of the mantle wedge is indicated by within-plate style trace element enrichment in Stromboli lavas. A similar mixing model is applicable to Roman province lavas and also to subduction related basalts throughout the world. Evidence is presented to suggest that variations in certain incompatible element ratios may result from the involvement of small degree partial melting in the genesis of island arc basalts. However it is clear that such a process is not solely responsible for the anomalous trace element geochemistry of subduction related magmatism.
Algorithms for the Calibration and Correction of Texel Images Using Inertial Measurement Updates

Publisher: name: Utah State University

description: A 3D terrain map can be developed to survey the earth’s surface and provide scientists with a method of accurately modeling terrain. Some of the applications include agricultural surveys, disaster management, and object classification. In order to develop a 3D terrain map, a sensor must capture all of the data to create the map. This 3D mapping tool can be made by combining a sensor that take samples of points on the earth’s surface and combines that with a digital camera that takes an image and lays it across those samples of the earth.
In order to take data over a large area, the entire system is flown on a small drone and must be small enough to allow the drone to fly for several minutes. While the drone is flying, a GPS sensor tracks the system’s location and orientation while taking data so they can be correlated with the 3D terrain map. Utah State University has developed a sensor for this application, called a texel camera, which uses laser measurements, digital images, and a GPS system to develop 3D terrain maps. The texel camera includes methods for correcting the terrain maps using the physics of the sensors and the motion of the drone during flight.

description: Recent discoveries have shown that when two layers of van der Waals (vdW) materials are superimposed with a relative twist angle between their respective in-plane principal axes, the electronic properties of the coupled system can be dramatically altered. Here, we demonstrate that a similar concept can be extended to the optics realm, particularly to propagating polaritons, hybrid light-matter interactions. To do this, we fabricate stacks composed of two twisted slabs of a polar vdW crystal (MoO3) supporting low-loss anisotropic phonon polaritons (PhPs), and image the propagation of the latter when launched by localized sources (metal antennas). Our images reveal that under a critical angle the PhPs isofrequency curve (determining the PhPs momentum at a fixed frequency) undergoes a topological transition. Remarkably, at this angle, the propagation of PhPs is strongly guided along predetermined directions (canalization regime) with no geometrical spreading (diffraction-less). These results demonstrate a new degree of freedom (twist angle) for controlling the propagation of polaritons at the nanoscale with potential for nano-imaging, (bio)-sensing, quantum applications and heat management.

title: The transformation of London's water supply, 1805-1821
Creators: name: Graham-Leigh, John David
Publisher: name: The Open University
Year: 1985

description: In 1805 London was supplied with water by several old-established companies which used the traditional method of distribution by gravity, through wooden pipes, from reservoirs which were at no great elevation above the districts supplied. The New River Company was by far the largest of these. Supplies were intermittent and unreliable, and many of the suburbs had no piped water supplies at all. During the period 1805-1811 a number of new companies were set up, initially with the purpose of supplying the neglected areas on the outskirts. They used the latest technology of steam engines and cast iron pipes to give a high-pressure supply, and due to the iron pipes their supplies were more reliable, although they generally kept the intermittent system. They soon began to compete directly with the established companies, causing these to lose many customers and to experience severe financial difficulties. The new companies themselves, however, also had financial problems. They expanded their systems too rapidly, in a period of high prices, so that they needed very large capital investment, their share prices were manipulated by speculators, and no adequate return on their capitals could be gained from water charges, which were in general reduced as an inevitable result of competition. The old and new companies recognised that the competition was likely to ruin them all, and in 1815-1818 agreed boundaries giving each company an exclusive area of supply. They then substantially increased their charges, which led to furious agitation against them by groups of consumers, A Parliamentary Select Committee investigated the question in 1821 and found that the companies had generally acted reasonably. As a result of the competition and agreements among the companies, London in 1821 had a much more abundant and regular water supply, using the most up-to-date methods, than ever before.

description: Challenges that are placed in front of banks have put changes towards business conditions, in terms, of increasing and reducing avaliable funds, have forced its management toward changing its business philosophy as well as the establishment of a new concept, which could respond to those challenges. For this reason, during the 80’s a concept of simultaneous managenemt of assets and liabilities has been developed, which is also known, in terms of banking terminology, under the shortcut ALM (Assets and Liabilities Management). A Bank, whose goals are success and competitiveness on the market, has to accept the development of the ALM approach as necessity or inevitable part of business. In accoradance with it, the success of the bank, in many cases will depend on the implementing quality of the ALM process. In order to evaluate the success of that activity, the bank, however, have to be familiar with the essence of the ALM concept, along with the basic criteria on which this evaluation is done. The goal of this paper is to present the essence of this concept and the criterias, which are the starting point during its evaluation.

For $^{179}$Hf, also $α$ decay to the ground state of $^{175}$Yb was searched for thanks to the $β$-instability of the daughter nuclide $^{175}$Yb. The measurements were conducted using an ultra low-background HPGe-detector system located 225 m underground. After 75 d of data taking no decays were detected but lower bounds for the half-lives of the decays were derived on the level of $\lim T_{1/2}\sim 10^{15}-10^{18}$~a. The decay with the shortest half-life based on theoretical calculation is the decay of $^{174}$Hf to the first $2^+$ 84.3~keV excited level of $^{170}$Yb. The experimental lower bound was found to be $T_{1/2}\geq 3.3\times 10^{15}$ a.

Socioscientific Issues in School-Based Agricultural Education: Describing and Exploring Factors of Integration
Creators: name: Burrows, Michelle S.
Publisher: name: Utah State University
Year: 2021

description: Socioscientific issues (SSI) are complex issues which are scientific in nature and have societal impacts. Many SSI have connections to agriculture and as such should be included in agricultural education curriculum. A clear understanding of what school-based agricultural education (SBAE) teachers know about SSI is needed. The purpose of this research was to explore the knowledge and integration of SSI among SBAE teachers by describing and explaining the factors that influence integration. This quantitative survey research was guided by the SSI-based instruction framework and the three-component model of agricultural education. The population for this study was all SBAE teachers in the U.S. and U.S. territories during the 2019-2020 school year. Participants could choose between an online or a paper and pencil version of the survey. A total of 136 SBAE teachers participated in the research.
School-based agricultural education teachers’ self-efficacy related to SSI, their perceived need to teach SSI and barriers to teaching SSI were explored. Survey responses were analyzed using descriptive statistics, ordinary least squares regression, and logistic regression. Findings suggest SBAE teacher self-efficacy was a significant predictor of overall SSI integration as well as the integration of climate issues, ecosystem and biodiversity, energy, food security, human population, and natural resource issues. Respondents agreed that SSI are needed in agricultural education but time to develop curriculum and integrate SSI is a barrier. Overall SBAE teachers felt supported by their administration and communities. The most taught SSI by respondents were natural resource, sustainability, and water issues; and the least taught SSI were energy, climate, and ecosystem and biodiversity issues. Although respondents indicated they were teaching SSI in their classes, the research results suggest that many were not using learning experiences aligned with the SSI-based instruction framework.
Recommendations included integration of SSI and the SSI-based instruction framework in both pre-service agricultural teacher preparation programs and in-service teacher professional development. Aligning state and national agricultural education standards to include SSI is also recommended. Further research should be conducted to explore SBAE teachers’ knowledge of SSI, how they are integrating SSI in their classes and what resources and teaching strategies they are using.

description: As part of our development of a computer code to perform 3D `constrained evolution' of Einstein's equations in 3+1 form, we discuss issues regarding the efficient solution of elliptic equations on domains containing holes (i.e., excised regions), via the multigrid method. We consider as a test case the Poisson equation with a nonlinear term added, as a means of illustrating the principles involved, and move to a "real world" 3-dimensional problem which is the solution of the conformally flat Hamiltonian constraint with Dirichlet and Robin boundary conditions. Using our vertex-centered multigrid code, we demonstrate globally second-order-accurate solutions of elliptic equations over domains containing holes, in two and three spatial dimensions. Keys to the success of this method are the choice of the restriction operator near the holes and definition of the location of the inner boundary. In some cases (e.g. two holes in two dimensions), more and more smoothing may be required as the mesh spacing decreases to zero; however for the resolutions currently of interest to many numerical relativists, it is feasible to maintain second order convergence by concentrating smoothing (spatially) where it is needed most. This paper, and our publicly available source code, are intended to serve as semi-pedagogical guides for those who may wish to implement similar schemes.

description: Transformation of organization concept is gaining importance in management theory, as well as in management practice. Technological, economical, political demografical and social changes are intensively gaining momentum, impacting discontinuities in numerous fields. Facing such challenges, organizations can not be sucessfull making only evolutive, incremental transformational changes. Contemporary organization needs significant, radical, „revolutional“- transformational change. Transformation leadership, along with revolutionary ways of creating a strategy, and implementation of strategical logic of inovative value, along with new transformation modalities creates a solid ground for a new management paradigm of contemporary organization

description: We investigate the spreading of 4He droplets on alkali surfaces at zero temperature, within the frame of Finite Range Density Functional theory. The equilibrium configurations of several 4He_N clusters and their asymptotic trend with increasing particle number N, which can be traced to the wetting behavior of the quantum fluid, are examined for nanoscopic droplets. We discuss the size effects, inferring that the asymptotic properties of large droplets correspond to those of the prewetting film.

description: Recent work in Utah’s northern Uinta Basin documents associations between variability in precipitation and fluctuating populations during the Fremont period, AD 300-1350. In this study, I evaluate the role that precipitation variability had on observed regional population density and settlement patterns. I test a model of village formation in Cub Creek, Utah across the larger Uinta Basin and its periphery by creating two predictive statistical models using archaeological data anchored in space and time. I conclude that while precipitation variability plays a role in the initial adoption of farming practices which itself leads to higher population densities, changes in patterns of precipitation variability do not appear to be directly associated with increasing population density in all sub-regions of my study area. Rather, the results of my study support the idea that increased population densities may be more related to the specific environmental and geographical structure of smaller regions across the study area. This study is important for understanding how precipitation variability may influence the growth of Fremont villages as well as their decline. This research contributes to Fremont archaeology as well as broader research into human culture by addressing changes in diet and settlement strategies within growing agricultural communities and climate variability.

description: This protocol contains Imaris creation parameter files for the analysis of Pseudomonas aeruginosa bacteria. These creation parameters were used to analyze Pseudomonas planktonic and aggregated cells (Pseudomonas_surfaces_planktonic_and_aggregate). Planktonic and aggregate analysis was designed with and is intended to be used on 3D confocal microscopy images of Pseudomonas aeruginosa. 

Also included are Imaris creation parameters for the analysis of Pseudomonas motility. There are two files for motility tracking. One is specifically used to track only the motile cells within a particular field (Motilty_tracking_motile_cells) and the other for tracking all cells, including non motile or those that do not meet motility criteria (Motility_tracking_all_cells). Motility tracking analysis was designed with and is intended to used on 2D, high speed (>10frames per second) confocal microscopy videos of Pseudomonas aeruginosa.
Spatial and Temporal Patterns of River Incision and Terrace Deposition in Response to Climate and Tectonics in Southern Taiwan

description: Geologists often look at the Earth’s surface to understand the underlying processes that cause mountain formation. As tectonic forces drive uplift of Earth’s surface, processes of erosion transport sediment to lower elevations. Climate can play a large role in landscape formation as well as increased precipitation, accelerating rates of erosion. Rivers leave markers of landscape evolution through terrace landforms, former river floodplains that are left behind when rivers incise into a valley. To better understand landscape response to uplift, this research investigated the initial linkages between uplift, hillslope erosion (mass wasting) and river incision. At some point, it is thought that these three will be in equilibrium. Taiwan is a young mountain range making it the ideal setting to capture landscape development in the initial stages of uplift. I compare rates of river incision to rates of hillslope erosion and timing of terrace deposition to understand the links between erosion, tectonics and climate in the beginning stages of mountain building.
This thesis uses luminescence to provide age control for the last time sediment was exposed to light to determine when river terraces formed. Field mapping and observations allowed us to measure the height between terraces to quantify the rate at which streams incised. The results from this study show that the rivers of southern Taiwan are incising on average at a rate of 2.4 ± 1.2 meters per thousand years (m/kyr) with rates ranging from 6 ± 2.6to 0.2 ± 0.1 m/kyr. River incision rates and hillslope erosion (denudation) rates increase northward with drainage development suggesting that rates of erosion are primarily linked to tectonic forces on medium to longer-term scales (1,000-1,000,000 years) . Regional periods of terrace development occurred at 1, 11, 18, 28, and 40 ka. Periods of terrace development align with periods of increased East Asian Summer Monsoon (EASM) intensity chronicled in paleoclimate records. The EASM is the dominate weather pattern that delivers moisture to East Asia affecting 1/3 of global populations. Terrace deposits recording EASM intensity extends the record of landscape response to climate in Taiwan and reveals that climate signals can obscure tectonic forces on short-time scales (100 – 103 yrs).
Monitoring Populations and Movement of Bobcats (Lynx rufus) on the Eastern Slope of the Sierra Nevada Mountains of California

description: Monitoring the spatial ecology and population densities of carnivores is critical for effective management and conservation of these populations and the ecosystems in which they exist. However, effective monitoring of carnivore populations through estimates of space use, habitat selection and densities can be difficult due to their relatively low densities and wide ranging, elusive behaviors. Bobcats (Lynx rufus) are medium sized, top-level predators which are widely distributed across North America. Quantifying space use, habitat selection and developing effective population monitoring strategies for this species will have important implications for wildlife management.
My first objective was to use telemetry data to evaluate space use parameters such as home range and core area estimates, seasonal movement patters and relative habitat selection of bobcats on the eastern slope of the Sierra Nevada Mountains of California, USA. Using GPS collars, I collected data on 38 bobcats (male n = 25, female n = 13) from 2015-2018. Using kernel density home range analysis, I was successfully able to estimate home range and core area sizes for male and female bobcats and examine differences in size between sexes and between seasons. Furthermore, I developed resource selection functions (RSF) to explore relative habitat selection of male and female bobcats in the study area.
My second objective was to evaluate accurate, non-invasive monitoring strategies for bobcats. Using camera trap data, I compared closed capture mark-recapture (CMR) and spatially explicit capture-recapture (SECR) methods for estimating densities of bobcats. Data was collected over a 6-week survey period in April-May of 2018. The different methods yielded very different estimates of density and spatial scale parameters. These differences likely stem from a low positive identification rate of bobcats based on pelage patterns. My findings suggest that in sparsely vegetated, open, homogenous desert ecosystems that photographic mark recapture may not be appropriate due to low identification rate of individuals.
To my knowledge, my study provides the first evaluation of space use and habitat selection by bobcats on the eastern slope of the Sierra Nevada Mountains of California. Furthermore, very little research has been conducted evaluating bobcat density and monitoring strategies in this area. The findings from this study will facilitate management and monitoring of bobcats in the eastern Sierra Nevada as well as providing important insights into the spatial ecology of bobcats in this area.
Effects of misalignment on response uniformity of SiPM-on-tile technology for highly granular calorimeters

description: The SiPM-on-tile technology, consisting of plastic scintillator tiles with typical sizes of a few cm$^2$ mounted on top of SiPMs, has been developed within the CALICE collaboration to enable automatized mass production of active elements for scintillator-based highly granular calorimeters. We present a study of the impact of misalignment of the scintillator tile with respect to the photon sensor on the response uniformity and on the absolute light yield for square, hexagonal and rhomboidal scintillator tiles of different sizes. A misalignment results in the formation of a dipole asymmetry of the spatial distribution of the light yield, with a magnitude that scales linearly with the size of the displacement, while the average light yield over the full active area of the tile is not affected. These results provide guidance for the definition of tolerances for the production and assembly of large calorimeter systems, showing that an alignment precision of approximately 500 $μ$m or better allows to limit the impact to acceptable levels.

Effect of the shot-noise on a Coulomb blockaded single Josephson junction

description: We have investigated how the Coulomb blockade of a mesoscopic Josephson junction in a high-impedance environment is suppressed by shot noise from an adjacent junction. The presented theoretical analysis is an extension of the phase correlation theory for the case of a non-Gaussian noise. Asymmetry of the non-Gaussian noise should result in the shift of the conductance minimum from zero voltage and the ratchet effect (nonzero current at zero voltage), which have been experimentally observed. The analysis demonstrates that a Coulomb blockaded tunnel junction in a high impedance environment can be used as an effective noise detector.

description: We present an algorithm to study mixed-state dynamics in one-dimensional quantum lattice systems. The algorithm can be used, e.g., to construct thermal states or to simulate real time evolutions given by a generic master equation. Its two main ingredients are (i) a superoperator renormalization scheme to efficiently describe the state of the system and (ii) the time evolving block decimation (TEBD) technique to efficiently update the state during a time evolution. The computational cost of a simulation increases significantly with the amount of correlations between subsystems but it otherwise depends only linearly in the system size. We present simulations involving quantum spins and fermions in one spatial dimension.
