Long-Term Hydrologic Responses To Shrub Removal In A SW Texas Rangeland: Using Soil Chloride To Estimate Deep Drainage

Long-Term Hydrologic Responses to Shrub Removal in a SW Texas Rangeland: Using Soil Chloride to Estimate Deep Drainage. (August 2009) David Anthony Barre, B.S., The University of Canberra Chair of Advisory Committee: Dr. Georgianne Moore The Carrizo-Wilcox aquifer is a valuable groundwater resource, situated in a semi-arid landscape of Southwest Texas, where over-use by dependent farming practices has lowered aquifer levels. In semi-arid regions, rates of groundwater recharge are predominantly low due to high potential evapotranspiration rates; however, least understood is the role that vegetation plays in soil-plant-water dynamics. Vegetation management potentially plays a major role in countering the loss to recharge because evapotranspiration (ET) varies with vegetation type and cover. The conversion from shrubland to grassland likely reduces rooting depths and total plant cover. Subsequently, deep drainage (percolation below the root zone) will likely increase and lead to groundwater recharge, at least temporarily. The primary aims of the study were to identify those biotic and abiotic factors facilitating deep drainage and to examine differences in recharge for the years following clearing of natural shrub vegetation. Soil chloride was examined to estimate long-term recharge rates, since its concentration in the soil is influenced by the movement of water. Short-term soil moisture trends were also monitored for any water movement deep in the soil profile in response to individual
The Role of Soil Organic Matter Quality and Physical Environment for Nitrogen Mineralization at the Forest-Tundra Ecotone in Fennoscandia

Abstract Nitrogen availability is considered limiting for plant growth at the forest-tundra ecotone, and it might modulate ecosystem response to climate warming. The aim of this research was to compare the impact of climate, vegetation cover, and soil organic matter (SOM) chemistry on N mineralization rates at the forest-tundra ecotone. We therefore estimated N mineralization in mountain birch (Betula pubescens Ehrh. ssp. czerepanovii) forest and tundra soil across a broad-scale latitudinal gradient in Fennoscandia, which incorporated 4 research sites (Dovrefjell, Vassijaure, Abisko, and Joatka). During the summer period, ammonium was the dominant form of mineralized nitrogen in forest soils, while nitrate mineralization rates were higher at tundra sites during the winter. A negative regression relationship between an index of climatic continentality and N mineralization was found. Further, summer NH4+ mineralization rates increased with total N content in soils, while NO3− mineralization seemed to be associated with C availability. Our study showed markedly contrasting inorganic N release in forest and tundra soil, and that, although mineralization rates differed between the summer and winter period, the winter activity was relatively high and should not be ignored. We conclude that a shift in the forest-tundra ecotone in response to climate warming will have stronger effects on nitrogen availability at these sites than the direct effects of warming.
Optimal Estimation in Networked Control Systems Subject to Random Delay and Packet Drop

— In this paper we study optimal estimation design for sampled linear systems where the sensors measurements are transmitted to the estimator site via a generic digital communication network. Sensor measurements are subject to random delay or might even be completely lost. We show that the minimum error covariance estimator is time-varying, stochastic, and it does not converge to a steady state. Moreover, the architecture of this estimator is independent of the communication protocol and can be implemented using a finite memory buffer if the delivered packets have a finite maximum delay. We also present two alternative estimator architectures which are more computationally efficient and provide upper and lower bounds for the performance of the time-varying estimator. The stability of these estimators does not depend on packet delay but only on the overall packet loss probability. Finally, algorithms to compute critical packet loss probability and estimators performance in terms of their error covariance are given and applied to some numerical examples.
Biomarkers of Exposure to Foodborne and Environmental Carcinogens: Enterosorbent Intervention in a High Risk Population

Biomarkers of Exposure to Foodborne and Environmental Carcinogens: Enterosorbent Intervention in a High Risk Population. (August 2010) Natalie Malek Johnson, B.S., Texas A&M University Chair of Advisory Committee: Dr. Timothy D. Phillips The need to assess human exposures to foodborne and environmental carcinogens, particularly in populations at high risk for cancer and disease, has led to the development of chemical-specific biomarkers. Sensitive biomarkers for aflatoxin and polycyclic aromatic hydrocarbons (PAHs) have been useful in providing information on population exposure and reducing associated public health impacts. Aflatoxins are fungal metabolites found in a variety of foods. Among these toxins, aflatoxin B1 (AFB1) is the most predominant and hepatocarcinogenic. Acutely, AFB1 can cause disease and death, necessitating safe and effective intervention strategies. Inclusion of NovaSil (NS) clay in the diet represents a practical, sustainable approach. NS has been shown to prevent aflatoxicosis in multiple animal species by binding aflatoxins in the gastrointestinal tract, reducing toxin bioavailability. Co-exposure to PAHs, hazardous environmental contaminants, has been shown to increase the risk for hepatocellular carcinoma (HCC). Therefore, objectives of this research were to utilize biomarkers to assess aflatoxin and PAH exposures in susceptible populations in Ghana and the U.S. and to evaluate the safety and efficacy of NS intervention in Ghana (a population at risk for aflatoxicosis).
The role of simulation in teaching pediatric resuscitation: current perspectives

: The use of simulation for teaching the knowledge, skills, and behaviors necessary for effective pediatric resuscitation has seen widespread growth and adoption across pediatric institutions. In this paper, we describe the application of simulation in pediatric resuscitation training and review the evidence for the use of simulation in neonatal resuscitation, pediatric advanced life support, procedural skills training, and crisis resource management training. We also highlight studies supporting several key instructional design elements that enhance learning, including the use of high-fidelity simulation, and debriefing. Simulation-based training is an effective modality for teaching pediatric resuscitation concepts. Current literature has revealed some research gaps in simulation-based education, which could indicate the direction for the future of pediatric resuscitation research.
Studies on the equilibria and kinetics of the reactions of peroxidase with ligands. II. The reaction of ferroperoxidase with oxygen.

Abstract Ferrous horseradish peroxidase, when mixed rapidly with oxygen-containing solutions, reacts with 1 molecular equivalent of oxygen to form 1 molecular equivalent of a product, oxyperoxidase. This reaction follows second order kinetics and proceeds without detectable intermediates. Ferrous peroxidase when titrated with oxygen yields 4 moles of ferric peroxidase for every mole of oxygen consumed. We believe that in this reaction the initial product is oxyperoxidase, which subsequently reacts with a further 3 moles of ferroperoxidase. Oxyperoxidase, therfore, retains all 4 oxidizing equivalents of the oxygen. The spectrum of oxyperoxidase closely resembles that of oxyhemoglobin and is very similar to that of the previously described Compound III of peroxidase. On the basis of this and other evidence we suggest that Compound III is actually oxyperoxidase. Our preparations of oxyperoxidase undergo a slow, spontaneous decay to ferric peroxidase; the process follows first order kinetics and no intermediates are detected. We have been unable to show dissociation of oxyperoxidase, even with an intense light pulse. Oxyperoxidase oxidizes dithionite directly, in a reaction not found in other heme proteins. Oxyperoxidase on the one hand shows striking similarities to other oxyheme proteins, and on the other hand may accept electrons, for example, from dithionite or ferroperoxidase. The conjunction of these properties in one molecule makes it a prototype of a terminal oxidase.
Multimicrophone Speech Dereverberation Using Spatiotemporal and Spectral Processing

— Speech signals acquired in a reverberant room with microphones positioned at a distance from the talker are degraded in quality due to reverberation and measurement noise. Therefore, enhancement of reverberant speech is important in hands-free telecommunications applications. The perceptual effects of reverberation can be linked to the room impulse response (RIR) between the talker and the microphone and are characterized by: (i) colouration, due to the strong early reflections and (ii) a distant 'echoey' quality due to the decaying tail of the RIR. Accordingly, we present a two-stage multimicro-phone method for speech dereverberation. First, spatiotemporal averaging is performed on the linear prediction residual, which primarily reduces the effects of the early reflections. Secondly, a spectral subtraction method is employed to reduce late reverberation. Simulation results with measured RIRs and additive white Gaussian noise illustrate the performance of this method and show that the combined approach performs better than each of the two stages individually.

Constructing MSR codes with subpacketization 2n/3 for k + 1 helper nodes

Wang et al. (IEEE Transactions on Information Theory, vol. 62, no. 8, 2016) proposed an explicit construction of an (n = k + 2, k) Minimum Storage Regenerating (MSR) code with 2 parity nodes and subpacketization 2k/3. The number of helper nodes for this code is d = k + 1 = n − 1, and this code has the smallest subpacketization among all the existing explicit constructions of MSR codes with the same n, k and d. In this paper, we present a new construction of MSR codes for a wider range of parameters. More precisely, we still fix d = k+1, but we allow the code length n to be any integer satisfying n ⩾ k + 2. The field size of our code is linear in n, and the subpacketization of our code is 2n/3. This value is slightly larger than the subpacketization of the construction by Wang et al. because their code construction only guarantees optimal repair for all the systematic nodes while our code construction guarantees optimal repair for all nodes.
Rate-distortion Bounds on Location-based Routing Protocol Overheads in Mobile Ad Hoc Networks

— Understanding the lower bounds on the amount of protocol overhead incurred for location-based routing of data packets is important for development of efficient routing protocols, and for understanding the actual (effective) capacity available for network users. In this paper we use an information-theoretic approach for characterizing the minimum routing overheads incurred by geographic routing in a mobile one-dimensional network. We formulate the minimum overhead problem as a rate-distortion problem. The formulation may be applied to networks with arbitrary traffic arrival and location service schemes. We evaluate a lower bound on the minimum routing overheads incurred by geographic routing in maintaining location of destination nodes and consistent neighborhood information in terms of node mobility and packet arrival process. We also discuss the deficit caused by the routing overheads in the overall transport capacity of a mobile network. I. INTRODUCTION Mobile ad hoc networks are characterized by variable link quality due to fading and multipath effects, and variable topology due to random arrival/departure and mobility of nodes. This makes routing packets in an ad hoc network a very challenging problem. Routing protocols either fail to cope with the variability and yield low packet delivery rate or incur very high overhead. It is important to understand the lower limits of overhead incurred for routing packets with certain level of reliability. Knowledge of such a fundamental overhead limit would not only allow the researchers to know how much a protocol deviates from the optimal but also inspire the development of routing protocols that achieve the limit. The primary goal of a routing protocol is to gather and disseminate state information such that a node may take packet forwarding decisions such that certain performance criteria are satisfied. The state information may comprise link states, location information, velocity and direction of nodes, queue lengths, etc. The performance criteria could be minimum delay, maximum throughput, maximum lifetime, or delivering certain fraction of packets. Information theory provides us with the lower bounds on minimum number of bits required to encode given information. Thus, it is reasonable to expect that information theory would be a suitable tool for developing lower bounds on the amount of overhead incurred by routing protocols for disseminating and gathering state information in a mobile ad hoc network.
Optimal Executive Compensation vs. Managerial Power: a Review of Lucian Bebchuk and Jesse Fried's Pay without Performance: the Unfulfilled Promise of Executive Compensation

This essay reviews Bebchuk and Fried's Pay without Performance: The Unfulfilled Promise of Executive Compensation. Bebchuk and Fried criticize the standard view of executive compensation, in which executives negotiate contracts with shareholders that provide incentives that motivate them to maximize the shareholders' welfare. In contrast, Bebchuk and Fried argue that executive compensation is more consistent with executives who control their own boards, and who maximize their own compensation subject to an " outrage constraint ". They provide a host of evidence consistent with this alternative viewpoint. The book can be evaluated from both positive and a normative perspectives. From a positive perspective, much of the evidence they present, especially about the camouflage and risk-taking aspects of executive compensation systems, is fairly persuasive. However, from a normative perspective, the book conveys the idea that policy changes can dramatically improve executive compensation systems and consequently overall corporate performance. It is unclear to me how effective in practice are potential reforms designed to achieve such changes likely to be. to thank Lucian Bebchuk and Jesse Fried, as well as Roger Gordon, for a number of useful suggestions. In addition, many thanks go to Ben Hermalin for his substantial comments, and more importantly, for his influence on my views on corporate governance that are reflected throughout this review.
Proximity Queries and Penetration Depth Computation on 3D Game Objects

This paper discusses methods for performing proximity queries (collision detection, distance computation) and penetration depth computation on a large class of convex objects. The penetration depth of a pair of intersecting objects is the shortest vector over which one object needs to be translated in order to bring the pair in touching contact. The class of objects includes convex primitives such as polytopes (line segments, triangles, convex polyhedra) and quadrics (spheres, cones, cylinders), as well as shapes derived from these primitives by affine transformation and spherical expansion (inflating an object by a given offset).
Tree Diameter Models from Field and Remote s ensing data

The objective of research is to find DBH prediction models that: use variables derived from remote sensing, field mensuration and previous forest inventory data; can be used in STRS methods; are suitable for Latvian forest conditions. In paper different tree DBH predicting models from field and remote sensing data were researched. The study site is a forest in middle of Latvia at Jelgava district (56o39' N, 23o47' E). The area consists of mixed coniferous and deciduous forest with different age, high density, complex structure, various components, composition and soil conditions. Aerial photography camera (ADS 40) and laser scanner (ALS 50 II) was used to capture the data. LiDAR resolution is 9p/m2 (500 m altitude). The image data is RGB, NIR and PAN spectrum with 20 cm pixel resolution. Image processing was made using Fourier transform, frequency filtering and reverse Fourier transform. LiDAR data processing methods was based on canopy height model, Gaussian mask and local maxima. Field measurements are tree coordinates, species, height, diameter at breast height, crown width. Totally seven different linear models were developed, using data collected. General linear model that predicts DBH includes a tree height, effective crown area, soil type and age factors. It showed strongest relationship between predicted and measured DBH (R 2 = 0,872). Summary results show that the models predict DBH reasonably well and factors included in all models are significant. Using combined LiDAR and optical imagery data is able to detect at least 63 % of all trees and about 85% of the dominant trees. Not identified trees at 82% of cases diameter at breast height was less than 20 cm and 88% of cases height was less than 20 m. Relationship between the Lidar detected height and observed total height shows showed strong relationship (R 2 = 0,986), also between Lidar and aerial photography detected and observed tree crown is strong relationship (R 2 = 0,869).
