description: BiOS 2000 The International Symposium on Biomedical Optics, 22-28 JANUARY, 2000, San Jose, CA, United States
description: In this work, we present a novel method for the simultaneous acquisition of ultrasonic attenuation and optical absorption using photoacoustically-generated ultrasound. We discuss the theory behind the technique and apply the method to measurements in mammalian tissue samples. We show that the frequency dependence of ultrasonic attenuation measured with this technique is consistent with conventionally determined values and thus holds promise for future work.

description: Several factors such as clinical stage at diagnosis, lymph node involvement, and access to treatment influence cervical cancer survival. The role of HPV status (positive or negative) in cervical cancer prognosis is not well defined. If HPV status were found to influence the course of cervical cancer, it could be used to inform treatment intensity. We will summarize the impact of testing HPV-positive on cervical cancer prognosis by conducting a systematic review and meta-analysis . Here, we provide the protocol for the proposed systematic review and meta-analysis.
Quantifying sources of fecal contamination in a coastal system with complex stormwater dynamics
Creators: name: Hart, Justin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Coastal North Carolina (NC) exhibits complex meteorological and hydrological dynamics that facilitate the delivery of fecal contaminants to downstream receiving waters via stormwater runoff. A quantitative microbial assessment of stormwater in Beaufort, NC was conducted to identify trends and potential sources of fecal contamination. During wet weather, the increase in microbial contaminants in receiving waters was substantial. Short-term rainfall (i.e. less than 12 hours) was predictive of E. coli, Enterococcus spp., and human-specific marker concentrations in receiving water, and strong correlation between 12-hr antecedent rainfall and Enterococcus spp. (r=0.57, p<0.001, n=92) suggests there is potential for a predictive model to be developed that would improve management of water quality impairment. These data will be used to inform ongoing stormwater mitigation projects in this region and serve as a conceptual model for the interaction between complex stormwater dynamics and water quality impairment in coastal NC.

description: We describe a series of experiments involving the creation of cylindrical packings of star-shaped particles, and an exploration of the stability of these packings. The stars cover a broad range of arm sizes and frictional properties. We carried out three different kinds of experiments, all of which involve columns that are prepared by raining star particles one-by-one into hollow cylinders. As an additional part of the protocol, we sometimes vibrated the column before removing the confining cylinder. We rate stability in terms of r, the ratio of the mass of particles that fall off a pile when it collapsed, to the total particle mass. The first experiment involved the intrinsic stability of the pile when the confining cylinder was removed. The second kind of experiment involved adding a uniform load to the top of the column, and then determining the collapse properties. A third experiment involved testing stability to tipping of the piles. We find a stability diagram relating the pile height, h, vs. pile diameter, delta, where the stable and unstable regimes are separated by a boundary that is roughly a power-law in h vs. delta with an exponent that is less than one. Increasing friction and vibration both tend to stabilize piles, while increasing particle size can destabilize the system under certain conditions.

Care Workers and Mobility: An Exploratory Analysis of the Effects of Job Changes on Wages
Creators: name: Ribas, Vanesa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Much of the literature on care workers focuses on issues of retention and recruitment, which are especially important to those concerned with the long-term care industry. On the other hand, researchers who study low-wage workers emphasize the barriers these workers face in escaping low earnings by remaining in low-wage industries and firms that offer a low wage premium. Despite this tension, not enough is known about how workers fare when they leave (or stay in) care work. The main questions I seek to answer are the following: What is the relationship between different job and occupational mobility patterns and wage growth for individuals employed as nurse aides? Do some kinds of transitions offer workers employed as nurse aides better opportunities to escape low wages? Are some types of workers more likely to make certain kinds of transitions than others? The findings illustrate the importance of looking at occupation-specific work trajectories and comparing different groups of workers to explain wage outcomes for workers, as well as to better understand their labor market behavior.

description: The genes PTPN22 and HLA-DRB1 have been found by a number of studies to confer an increased risk for rheumatoid arthritis (RA), which indicates that both genes play an important role in RA etiology. It is believed that they not only have strong association with RA individually, but also interact with other related genes that have not been found to have predisposing RA mutations. In this paper, we conduct genome-wide searches for RA-associated gene-gene interactions that involve PTPN22 or HLA-DRB1 using the Genetic Analysis Workshop 16 Problem 1 data from the North American Rheumatoid Arthritis Consortium. MGC13017, HSPCAL3, MIA, PTPNS1L, and IGLVI-70, which showed association with RA in previous studies, have been confirmed in our analysis.

description: Breast cancer is the most common cancer among Canadian women. Total mastectomy may be an important component of breast cancer treatment and, for many women, may include breast reconstruction. Reconstruction of the breast mound can be performed at the time of ablative surgery, known as immediate breast reconstruction (IBR). The time between a patient’s breast cancer diagnosis and their mastectomy with or without IBR is quite short, such that many patients are left dissatisfied and without enough understanding to make an informed decision following their surgical consultation. Another barrier within this process is that many patients may not know how to engage in the conversation and ask the questions they want to hear answers to. Question prompt lists and decision-making tools have shown to help patients with this issue. The aim of this scoping review is to determine what literature and resources exist on checklists and decision-making tools for post-mastectomy patients undergoing breast reconstruction both within academic and non-academic mediums. We will examine what kind of resources exist for this population, how accessible they are, which platforms they’re published on and their efficacy.

A STEAM Approach to Investigating the Hydrologic Cycle
Creators: name: Kniffin, Maribeth
Publisher: name: QUBES Educational Resources
Year: 2023

description: The purpose of this experiential lesson is to teach introductory to mid-level undergraduate students how to make detailed hydrologic field observations into a conceptual model using a painting medium. Students should have prior knowledge about the hydrologic cycle and the hydrologic budget. Part I is the field component where students make detailed observations about key processes of the hydrologic cycle near a river while canoeing, kayaking, or hiking. Part II is an outdoor art-lab lesson where students explore the intersection of science and art, are introduced to conceptual models, and take their observations and sketches from Part I and create a painting to explore one of five key hydrologic cycle processes. Part III is a post-lesson written assignment for students to reflect on their experience demonstrating their knowledge about the hydrologic cycle in relation to the local hydrology. Equipment needed include a field notebook, paints, a canvas, and handouts. This lesson would be well-suited to an introductory earth science, hydrology, or hydrogeology course and can be helpful when introducing the concept of scientific models.

description: The center-to-limb variation (CLV) describes the brightness of the stellar disk as a function of the limb angle. Across strong absorption lines, the CLV can vary quite significantly. We obtained a densely sampled time series of high-resolution transit spectra of the active planet host star HD 189733 with UVES. Using the passing planetary disk of the hot Jupiter HD 189733 b as a probe, we study the CLV in the wings of the Ca II H and K and Na I D1 and D2 Fraunhofer lines, which are not strongly affected by activity-induced variability. In agreement with model predictions, our analysis shows that the wings of the studied Fraunhofer lines are limb brightened with respect to the (quasi-)continuum. The strength of the CLV-induced effect can be on the same order as signals found for hot Jupiter atmospheres. Therefore, a careful treatment of the wavelength dependence of the stellar CLV in strong absorption lines is highly relevant in the interpretation of planetary transit spectroscopy.

description: This study investigated the effects of a 10 km run and 30 km cycling time-trial on maximal oxygen uptake (VO2max) and ventilatory threshold (VT) during the subsequent run of an ITU Duathlon simulation. Highly-trained multi-sport subjects (n=6) completed three trials; Trial-1: a speed only VO2max (SOVO2max) protocol to determine VO2max and VT during an single-bout run; Trial-2: a 10 km run at 95-98% of VT followed by a cycle ergometer VO2max test to determine VO2max and VT; Trial-3: a 10 km run and 30 km cycling time-trial, each performed at 95-98% of VT, followed by a SOVO2max protocol to determine VO2max and VT. No significant difference in VO2max, (p=0.06, 66.8 mL/kg/min±6.6 and 60.9 mL/kg/min±3.1 respectively), or VT (%VO2max) (p=0.36, 75.9%±3.9 and 77.5%±10.4, respectively) was observed. A decrease of 1.6 km/h was observed between trials; a 2 minute and 18 second increase in 5 km run time.
A Mirror Image of the Eurozone Balance of Payments Problem: Using Theories of Institutionalism to Explore the International Monetary Fund’s Policy Paradigm Shift Due to Germany’s Current Account Surplus
Creators: name: Wilcox, Justin Chandler
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: This paper serves as an exploratory look into how Germany's current account surplus triggered a policy paradigm shift in institutional response to the persistent imbalance of payments problem during the eurozone crisis. It creates a narrative of how Germany's current account balance came into political focus and why international institutions, in particular the International Monetary Fund, shifted policies away from placing the burden of financial rebalancing on debtor countries toward a more equal policy of assigning some blame to creditor countries. The paper makes use of the concept of policy paradigm shifts and how these changes can occur within international institutions. It also discusses the measure of the current account and later argues that the burden of financial rebalancing is unfairly applied to only Germany, rather that the blame and burden is better assigned more widely to the North of Europe which also has high current account surpluses.

description: With the Thomson scattering (TS) system in KSTAR, temporal evolution of electron temperature ($T_e$) is estimated using a weighted look-up table method with fast sampling ($1.25$ or $2.5$ GS/s) digitizers during the 2014 KSTAR campaign. Background noise level is used as a weighting parameter without considering the photon noise due to the absence of information on absolute photon counts detected by the TS system. Estimated electron temperature during a relatively quiescent discharge are scattered, i.e., $15$\% variation on $T_e$ with respect to its mean value. We find that this $15$\% variation on $T_e$ cannot be explained solely by the background noise level which leads us to include photon noise effects in our analysis. Using synthetic data, we have estimated the required photon noise level consistent with the observation and determined the dominant noise source in KSTAR TS system.

Joint Formation in the Caudal Fin Rays of Danio rerio (Zebrafish) During Fin Regeneration
Creators: name: Sheppard, Derek

Subjects: Zebrafish
Regeneration

description: Danio rerio, more commonly called zebrafish, possess the ability to regenerate many of their organs and appendages including complete regeneration of the caudal fin back to its original size. The caudal fin consists of 16-18 fin rays (lepidotrichia) separated by interray tissue. These fin rays consist of bone segments that are partitioned by joints. Each bone segment consists of two oval shaped hemirays that form a tube-like structure that houses a multitude of tissues. During regeneration, the fin ray elongates through the distal addition of bone segments separated by newly formed joints. This is all regulated by a highly proliferative group of cells called the blastema located in the most distal portion of the regenerating fin ray. Our lab has been able to distinguish different stages of joint maturation during the regenerative process which has led to an interest in the effects of joint cell ablation during regeneration. A transgenic line of zebrafish that contained lnta11 regulatory elements was found to give expression of a reporter in the joints of adult zebrafish. We used this regulatory element to drive expression of nitroreductase (NTR) in joint cells. In the presence of NTR, metronidazole (MTZ) induces ablation through initiation of the caspase dependent apoptosis cascade. Previous joint cell photoblation results in our lab indicated that joints may not be able to regenerate, we wanted to determine the results of complete ablation of joint cells during regeneration using the NTR/MTZ inducible targeted ablation technique. Surprisingly treatment with MTZ did not completely eliminate the joints during regeneration. However, there was a reduction in segment length and overall fin length of fish treated with MTZ compared to controls. Furthermore, as the concentration of MTZ is increased there is a proportional reduction in segment length of the fin regenerate. Although we failed to eliminate joints, the phenotype observed provided support for our proposed model of joint formation during regeneration. The creation of transgenic fish lines are underway to allow the separate ectopic expression of two transcription factors; sp7 (a known marker of osteoblast commitment) and hoxa13a (a hypothesized joint commitment factor) during regeneration.

description: Lifetime-imaging has quickly become a standard tool for many applications in biology, medicine, and engineering. Luminescence lifetime is dependent on the chemical environment surrounding the lumiphore so lifetime images give scientists far more chemical information than traditional images. Most lifetime imaging systems require the sample to be brought to the sample stage of a fluorescence lifetime microscope or other lifetime imaging set-up. We are developing lifetime- based fiber-optic imaging systems and sensors for a variety of in-situ measurements. In this work, small diameter optical imaging guides are used to carry light from an excitation source to a remote, or in-situ, sample and also to return the resulting luminescence image through the same image guide to a time-resolved imaging detector. For example, we have developed lifetime-based fiber-optic water and oxygen imaging sensors with the sensing chemistry directly attached to the distal tip of an image guide. These sensors use a pulsed excitation source and a gated camera (ICCD) to collect the images. In addition, we are developing a dual-pulse lifetime imaging system for remote imaging without a gated detector. This paper will report on the current status of our lifetime- based fiber-optic imaging sensors, dual-pulse methods and potential applications.

description: Fiber-optic chemical sensors (FOCS's) are useful for making remote, in-situ, and microscale measurements. Many intensity-based and lifetime-based FOCS's have been developed for a wide range of properties and analytes. Most of these sensors give only a single-point measurement however, recently a few intensity based imaging FOCS's have been described. We have developed intensity-based fiber- optic imaging systems to measure the transport of water in thin NafionTM membranes and to monitor the development of pH gradients at the surface of an electrode during electrolysis of water. However, intensity-based measurements are difficult to calibrate because of the dependence of luminescence intensity on many interfering factors including dye concentration and varying excitation intensity. As a result, we are developing lifetime-based fiber-optic imaging sensors for a variety of applications. At this point we have measured a lifetime image across a sol-gel crack using a fiber-optic image guide to carry the excitation light to the sample and the resulting luminescence image to an ICCD. Currently, we are testing an oxygen imaging FOCS to capture lifetime-based images of at least two different lifetimes. This paper describes the single-point, lifetime-based sensors we have developed as precursors to fiber-optic imaging chemical sensors, the intensity-based imaging studies of water transport in thin NafionTM membranes and the development of pH gradients at electrode surfaces. It also discusses the instrumental system and methods used to collect lifetime images of sol-gel cracks with a fiber- optic, and the preliminary results of our imaging oxygen sensor.

description: In this paper, we propose a novel technique to implement stochastic gradient methods, which are beneficial for learning from large datasets, through accelerated stochastic dynamics. A stochastic gradient method is based on mini-batch learning for reducing the computational cost when the amount of data is large. The stochasticity of the gradient can be mitigated by the injection of Gaussian noise, which yields the stochastic Langevin gradient method; this method can be used for Bayesian posterior sampling. However, the performance of the stochastic Langevin gradient method depends on the mixing rate of the stochastic dynamics. In this study, we propose violating the detailed balance condition to enhance the mixing rate. Recent studies have revealed that violating the detailed balance condition accelerates the convergence to a stationary state and reduces the correlation time between the samplings. We implement this violation of the detailed balance condition in the stochastic gradient Langevin method and test our method for a simple model to demonstrate its performance.

Year: 2009

description: Immigration continues to be a hot topic of debate among many European countries as they are now faced with complicated challenges to their social protection systems. Realistically, immigration alone is not enough to solve the problems of welfare states like Italy as widely believed but it can be a good source of economic and social benefits to the Italian system. Our aim is to produce a better understanding of how immigrants impact the Italian welfare system. We will examine their perceived effects on Italian society, the different welfare policy towards immigrants across Europe and look at the positive economic and social impacts that immigration has on the Italian state. Lastly, we will look at immigrant use of social services and compare it with their contributions. We hope to present a clearer picture of the positive impact of immigration in Italy and immigrants' significant role in sustaining the welfare state.

description: On-site determination of volatile organic pollutants in ground water supplies is important for remediation. A simple fiber- optic probe suitable for remote analysis using resonance enhanced multiphoton ionization has been developed and is used to determine the toluene concentration in water samples spiked with gasoline via a head space measurement. An optical fiber transmits a high power laser pulse (266 nm) to the sample, ionizing it, and the subsequent ions are collected with a platinum electrode. Measurements take approximately 1.5 minutes to perform, require no sample preparation, and have been demonstrated over distances of five meters. The limit of detection for toluene in water using this probe is 1.54 plus or minus 0.02 ppb (wt/wt). In addition to the 1 + 1 excitation, the feasibility of a 2 + 2 excitation scheme using 532 nm has been investigated.

description: Trotz umfangreicher öffentlicher Betreuungseinrichtungen wird auch in Frankreich auf migrantische Sorgearbeit zur Vereinbarkeit von Familie und Beruf zurückgegriffen. Der vorliegende Beitrag beschäftigt sich hiermit und verfolgt zwei Ziele: Aus einer intersektionalen Perspektive wird erörtert, inwieweit migrantische Sorgearbeit mit den Differenzkategorien Klasse, Geschlecht und race/Migration verbunden ist und im Kontext einer wohlfahrtsstaatlichen Rahmung steht. Diese Perspektive trägt dazu bei, die Konstruktion von Machtverhältnissen und die Herstellung von hierarchisch fungierenden Differenzen durch das wohlfahrtsstaatliche Handeln offenzulegen, auch im Hinblick auf die Wechselbeziehungen zwischen den Differenzkategorien. Indem der Bogen zur normativen Analyse von Care geschlagen wird, wird das Care-Regime in Frankreich beurteilt. Hierfür werden Leitprinzipien aus den Ansätzen des Inclusive Citizenship, der Soziabilität und des Capabilities Approach entwickelt.

description: A fiber-optic probe suitable for remote elemental analysis using laser-induced breakdown spectroscopy (LIBS) has been developed and has been used to determine the concentration of lead in samples of dry paint. To develop a suitable fiber- optic sensor for remote measurements using LIBS a number of key issues must be addressed. The issue of coupling high-power laser pulses into optical fibers without fiber damage was first addressed by measuring damage threshold values, and by performing long-term durability tests for several different fiber types and sizes. This study led to the design of a highly flexible fiber-optic LIBS probe that can be used for a variety of sample substrates. To address the issue of reproducibility, we are investigating matrix affects and the dynamics of the laser ablation and laser-induced plasma processes by using a variety of spectroscopic techniques including time-resolved spectroscopic imaging. We have also modified the probe so that laser ablated material can be injected into a mass spectrometer.

Some counterexamples to Sobolev regularity for degenerate Monge-Ampère equations
Creators: name: Mooney, Connor
Publisher: name: arXiv
Year: 2015
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: We construct a counterexample to $W^{2,1}$ regularity for convex solutions to $$\det D^2u \leq 1, \quad u|_{\partial Ω} = 0$$ in two dimensions. We also prove a result on the propagation of singularities in two dimensions that are logarithmically slower than Lipschitz. This generalizes a classical result of Alexandrov and is optimal by example.

description: This study aims to investigate differences in childbearing patterns among male and female HL survivors treated with ABVD and BEACOPP (and variants thereof) in Sweden, Denmark, and the Oslo region in Norway. Specifically, we aim to estimate: (1) absolute and relative rates of childbirth over time since index date (date of diagnosis + 9 months) and (2) cumulative incidence of first (and possibly recurrent) childbirths over time since index date.
Effects of knee extension constraint on knee flexion angle and ground reaction forces after ACL reconstruction
Creators: name: Stanley, Christopher J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Small knee flexion angles at initial contact and large ground reaction forces during landing have been identified as risk factors for non-contact anterior cruciate ligament injuries that are common in sports. This study investigated the effects of knee extension constraint on knee flexion angle and ground reaction forces for patients who were 4-6 months post ACL reconstruction surgery, and also compared these patients to healthy subjects' motion patterns. Three-dimensional videographic and force plate data were collected for 12 ACL reconstruction patients and 12 age and gender matched healthy subjects performing level walking, jogging, and stair descending under 3 conditions: knee brace with a constraint to extension, traditional knee brace, and no knee brace. The constrained knee brace significantly increased knee flexion angle at landing, but did not significantly affect the peak ground reaction forces at landing. The constrained knee brace may be useful in the prevention and rehabilitation of non-contact anterior cruciate ligament injuries in sports.
Thermally-induced optical reflection of sound (THORS) for photoacoustic sensing

description: The ability to precisely control and manipulate acoustic waves can be highly limiting in applications and environments where placement of physical barriers for acoustic steering cannot be employed (e.g. tissues, air, etc.) In this work, we describe the ability to generate acoustic waveguides via thermally-induced optical reflection of sound (THORS) for the manipulation of acoustic waves in free space (i.e., air). Abrupt, density barriers are formed by photothermally depleting the sample in a laser beam’s path via photothermal processes, resulting in sharp differences in compressibility and significant acoustic reflection (greater than 30%). Optical waveguiding of sound can be achieved by generating THORS channels with a cylindrical (ring shaped) laser beam. By containing the acoustic waves inside a THORS cylindrical channel, a dramatically reduced acoustic decay profile of 1/r0.6 with distance is achieved. Additionally, we describe the effects that optical modulation frequency of the THORS channel has on the efficiency of acoustic waveguiding. We also show how external acoustic waves, incident to a THORS channel are suppressed, increasing the signal-to-background ratio of the internally waveguided acoustic signals. Optical waveguiding of acoustic waves offers a new paradigm in the manipulation of sound over extended distances, providing potentially significant improvements to photoacoustic sensing, secure communications, and many other applications.

description: In 2014 an all-sky imager (ASI) and an Advanced Modular Incoherent Scatter Radar consisting of 14 panels (AMISR-14) system were installed at the Jicamarca Radio Observatory. The ASI measures airglow depletions associated with large-scale equatorial spread F irregularities (10s-100s km), while AMISR-14 detects small-scale irregularities (0.34 m). This study presents simultaneous observations of equatorial spread F (ESF) irregularities at 10-100 km scales using the all sky-imager, at 3 m scales using the JULIA (Jicamarca Unattended Long-term Investigations of the Ionosphere and Atmosphere) radar, and at 0.34 m scales using the AMISR-14 radar. We compare data from the three instruments on the night of 20-21 August, 2014 by locating the radar scattering volume in the optical images. During this night no topside plumes were observed, and we only compare with bottomside ESF. AMISR-14 had five beams perpendicular to the magnetic field covering ~200 km in the east-west direction at 250 km altitude. Comparing the radar data with zenith ASI measurements, we found that most of the echoes occur on the western wall of the depletions with fewer echoes observed the eastern wall and center, contrary to previous comparisons of topside plumes that showed most of the echoes in the center of depleted regions. We attribute these differences to the occurrence of irregularities produced at sub-meter scales by the lower-hybrid-drift instability. Comparisons of the ASI observations with JULIA images show similar results to those found in the AMISR-14 and ASI comparison.

Search for heavy resonances decaying into $WW$ in the $e\nu\mu\nu$ final state in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector
Creators: name: ATLAS Collaboration
Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2017

description: A search for neutral heavy resonances is performed in the $WW\to e\nu\mu\nu$ decay channel using $pp$ collision data corresponding to an integrated luminosity of 36.1 fb$^{-1}$, collected at a centre-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. No evidence of such heavy resonances is found. In the search for production via the quark--antiquark annihilation or gluon--gluon fusion process, upper limits on $\sigma_X \times B(X \to WW)$ as a function of the resonance mass are obtained in the mass range between 200 GeV and up to 5 TeV for various benchmark models: a Higgs-like scalar in different width scenarios, a two-Higgs-doublet model, a heavy vector triplet model, and a warped extra dimensions model. In the vector-boson fusion process, constraints are also obtained on these resonances, as well as on a Higgs boson in the Georgi--Machacek model and a heavy tensor particle coupling only to gauge bosons.
