description: It has recently been suggested that ultra-high energy cosmic rays could have an extragalactic origin down to the "second knee" at ~4x10^{17}eV. In this case the "ankle" or "dip" at ~5x10^{18}eV would be due to pair production of extragalactic protons on the cosmic microwave background which requires an injection spectrum of about E^{-2.6}. It has been pointed out that for injection of a mixed composition of nuclei a harder injection spectrum E^{-2.2} is required to fit the spectra at the highest energies and a galactic component is required in this case to fit the spectrum below the ankle, unless the proton fraction is larger than 85%. Here we perform numerical simulations and find that for sufficiently magnetized sources, observed spectra above 10^{19}eV approach again the case of pure proton injection due to increased path-lengths and more efficient photo-disintegration of nuclei around the sources. This decreases secondary fluxes at a given energy and thus requires injection spectra ~E^{-2.6}, as steep as for pure proton injection. In addition, the ankle may again be sufficiently dominated by protons to be interpreted as a pair production dip.

description: A Cox test with parametric bootstrap is developed to select between the linearized version of the First-Difference Almost Ideal Demand System (FDAIDS) and the Rotterdam model. A Cox test with parametric bootstrap has been shown to be more powerful than encompassing tests like those used in past research. The bootstrap approach is used with U.S. meat demand (beef, pork, chicken, fish) and compared to results obtained with an encompassing test. The Cox test with parametric bootstrap consistently indicates the Rotterdam model is preferred to the FDAIDS, while the encompassing test sometimes fails to reject FDAIDS.

description: We compute the quasinormal frequencies for scalar and electromagnetic perturbations of an improved Schwarzschild geometry in the framework of asymptotically safe gravity, which is one of the approaches to quantum gravity. Adopting the widely used WKB semi-classical approximation, we investigate the impact on the spectrum of the angular degree, the overtone number as well as the black hole mass. We summarize our numerical results in tables, and for better visualization, we show them graphically as well. All modes are found to be stable. Finally, we compare our numerical results with those corresponding to the classical Schwarzschild solution as well as to the results obtained using a different approach. Our findings show that i) a different cut-off identification does not affect the spectra significantly, and ii) for hypothetical objects with masses comparable to the Planck mass, the difference in the numerical values between the modes of the classical solution and the modes of the improved solution studied here is of the order of a few per cent. On the contrary, for realistic, astrophysical BHs no difference in the frequencies is observed.

description: The magnetic and transport properties of (GaMn)As are known to be influenced by postgrowth annealing, and it is generally accepted that these modifications are due to outdiffusion of Mn interstitials. We show that the annealing-induced modifications are strongly accelerated if the treatment is carried out under As capping. This means that the modification rate is not limited by the diffusion process, but rather by the surface trapping of the diffusing species.

description: The observation of a large Nernst signal $e_N$ in an extended region above the critical temperature $T_c$ in hole-doped cuprates provides evidence that vortex excitations survive above $T_c$. The results support the scenario that superfluidity vanishes because long-range phase coherence is destroyed by thermally-created vortices (in zero field), and that the pair condensate extends high into the pseudogap state in the underdoped (UD) regime. We present a series of measurements to high fields $H$ which provide strong evidence for this phase-disordering scenario.

description: We present a method for making microbubble whispering gallery resonators (WGRs) from tellurite, which is a soft glass, using a CO$_2$ laser. The customized fabrication process permits us to process glasses with low melting points into microbubbles with loaded quality factors as high as $2.3 \times 10^6$. The advantage of soft glasses is that they provide a wide range of refractive index, thermo-optical and optomechanical properties. The temperature and air pressure dependent optical characteristics of both passive and active tellurite microbubbles are investigated. For passive tellurite microbubbles, the measured temperature and air pressure sensitivities are 4.9 GHz/K and 7.1 GHz/bar, respectively. The large thermal tuning rate is due to the large thermal expansion coefficient of $1.9 \times 10^{-5}$ K$^{-1}$ of the tellurite microbubble. In the active Yb$^{3+}$-Er$^{3+}$ co-doped tellurite microbubbles, C-band single-mode lasing with a threshold of 1.66 mW is observed with a 980 nm pump and a maximum wavelength tuning range of 1.53 nm is obtained. The sensitivity of the laser output frequency to pressure changes is 6.5 GHz/bar. The microbubbles fabricated by this novel method have a low eccentricity and uniform wall thickness, as determined from electron microscope images and the optical spectra. The compound glass microbubbles described herein have potential for a wide range of applications, including sensing, as tunable microcavity lasers, and for integrated photonics.

description: The operatic singing tradition in Western classical music is defined by bel canto, an elusive technique or style of singing which cultivates one standardised, uniform, and beautiful vocal sound. In this singular aesthetic pursuit, bel canto disregards bodily aspects of the individual singer, and the voice is disembodied from the singer through an immaterial worship of one singular sound. This practice denies the plurality and dynamism that inherently make a voice unique and communicative. In this written commentary and submitted portfolio, I rematerialise the classical voice by studying the physical attributes of the bel canto technique alongside various vocal techniques, timbres, voice and movement pedagogies, and materialist theoretical works. Through this study, I recontextualise use of the modern classical voice in contemporary classical and avant-garde performance. Chapter 1 focuses on vocal timbres, the Nadine George Voice Work, and various applications of timbres and singing techniques in works by Georges Aperghis and Kate Soper. Chapter 2 examines the body and movement in multidisciplinary performance, and in particular finding movement within the voice. I document applied movement practices in works by Aperghis, Soper, and self-composed music. Chapter 3 looks to the environment, and vocal embodiment that happens outside the body and in collaboration with natural and sonic environments. I explore this concept in self-composed music, improvised music, and sound art. My doctoral Artistic Projects include a staged multidisciplinary performance of Georges Aperghis’ 14 Récitations entitled Recitations in Motion (Artistic Project 1), a staged multidisciplinary performance of Kate Soper’s chamber opera Ipsa Dixit (Artistic Project 2), a nature-themed sound album entitled Anthropocenic Garden, co-composed by me and Tom W. Green (Artistic Project 3), and a performance of a multidisciplinary concert work entitled Soroche, co-composed by me and Alistair MacDonald, in collaboration with writer Jessica Gaitán Johannesson (Development Project).

description: This paper presents estimates of the economic and demographic effects on the demand for steak, roast, and ground beef. Using an almost ideal demand system, the results indicate that demand is inelastic for steak and ground beef, elastic for roast, cross-price effects are significant, and all goods are Hicks-Allen substitutes. The impact of certain demographic effects, such as household size, region, tenancy, and ethnic origin, was generally quite significant. Other demographic variables, such as employment status, shopper, and occupation, were generally not significant.
Multimodal Learning from Videos: Exploring Models and Task Complexities
Creators: name: Palaskar, Shruti
Publisher: name: Carnegie Mellon University

Subjects: Multimedia Programming

description:  Human learning is inherently multimodal. We watch, listen, read, and communicate to learn from and understand our surroundings. There have been several advancements in machine learning fields related to these human activities such as speech recognition or computer vision that make computationally modeling this human-like inherent multimodal learning a possibility. Multimodal video understanding as a machine learning task is close to this form of learning. 
This thesis proposes to break down this complex task of video understanding into a series of relatively simpler tasks with increasing complexity. We start with the monotonic task of speech recognition and introduce an end-to-end audio-visual speech recognition model. A more complex task is speech translation that tackles re-ordered output sequences in addition to speech recognition, which is the second task in this thesis. For speech translation, we introduce a multimodal fusion model that learns to leverage the multiple views multimodal data provides in a semi-supervised way. Further, we progress to the tasks of multimodal video summarization and question answering that tackle abstract-level understanding tasks further involving information compression and restructuring. Finally, we extend this work to multimodal self-rationalization that not only performs abstract-level learning, but also provides an explanation of the achieved video understanding. For the four main tasks, we present a series of multimodal fusion models based on the nature and complexity of the task, the modalities involved in each and compare and contrast the models on commonly used video and language understanding datasets.

description: A stochastic dynamic programming model is developed to determine optimal replacement intervals and depreciation schedules for a combine on a cash grain farm in north central Montana, where the optimal decision is based on the stochastic nature of winter wheat prices. Empirical results indicate that the decision varies widely depending on the states describing the conditions facing the farm firm. Under normal profitable conditions and ERTA81 tax legislation, suggested replacement is after five years of service, the new asset being depreciated under the accelerated cost recovery system and the investment credit option. Changes to the tax law would tend to smooth out and increase this replacement interval.

description: Employing a nonequilibrium Green's function approach, we examine the effects of long-range hole-impurity scattering on spin-Hall current in $p$-type bulk semiconductors within the framework of the self-consistent Born approximation. We find that, contrary to the null effect of short-range scattering on spin-Hall current, long-range collisions do produce a nonvanishing contribution to the spin-Hall current, which is independent of impurity density in the diffusive regime and relates only to hole states near the Fermi surface. The sign of this contribution is opposite to that of the previously predicted disorder-independent spin-Hall current, leading to a sign change of the total spin-Hall current as hole density varies. Furthermore, we also make clear that the disorder-independent spin-Hall effect is a result of an interband polarization directly induced by the dc electric field with contributions from all hole states in the Fermi sea.

description: A high-angular momentum giant impact with the Earth can produce a Moon with a silicate isotopic composition nearly identical to that of Earth's mantle, consistent with observations of terrestrial and lunar rocks. However, such an event requires subsequent angular momentum removal for consistency with the current Earth-Moon system. The early Moon may have been captured into the evection resonance, occurring when the lunar perigee precession period equals one year. It has been proposed that after a high-angular momentum giant impact, evection removed the angular momentum excess from the Earth-Moon pair and transferred it to Earth's orbit about the Sun. However, prior N-body integrations suggest this result depends on the tidal model and chosen tidal parameters. Here we examine the Moon's encounter with evection using a complementary analytic description and the Mignard tidal model. While the Moon is in resonance the lunar longitude of perigee librates, and if tidal evolution excites the libration amplitude sufficiently, escape from resonance occurs. The angular momentum drain produced by formal evection depends on how long the resonance is maintained. We estimate that resonant escape occurs early, leading to only a small reduction (~few to 10%) in the Earth-Moon system angular momentum. Moon formation from a high-angular momentum impact would then require other angular momentum removal mechanisms beyond standard libration in evection, as have been suggested previously.

description: Domain-specific systems-on-chip, a class of heterogeneous many-core systems, are recognized as a key approach to narrow down the performance and energy-efficiency gap between custom hardware accelerators and programmable processors. Reaching the full potential of these architectures depends critically on optimally scheduling the applications to available resources at runtime. Existing optimization-based techniques cannot achieve this objective at runtime due to the combinatorial nature of the task scheduling problem. As the main theoretical contribution, this paper poses scheduling as a classification problem and proposes a hierarchical imitation learning (IL)-based scheduler that learns from an Oracle to maximize the performance of multiple domain-specific applications. Extensive evaluations with six streaming applications from wireless communications and radar domains show that the proposed IL-based scheduler approximates an offline Oracle policy with more than 99% accuracy for performance- and energy-based optimization objectives. Furthermore, it achieves almost identical performance to the Oracle with a low runtime overhead and successfully adapts to new applications, many-core system configurations, and runtime variations in application characteristics.

Dynamic avalanche breakdown of a p-n junction: deterministic triggering of a plane streamer front

Year: 2005

description: We discuss the dynamic impact ionization breakdown of high voltage p-n junction which occurs when the electric field is increased above the threshold of avalanche impact ionization on a time scale smaller than the inverse thermogeneration rate. The avalanche-to-streamer transition characterized by generation of dense electron-hole plasma capable to screen the applied external electric field occurs in such regimes. We argue that the experimentally observed deterministic triggering of the plane streamer front at the electric field strength above the threshold of avalanche impact ionization but yet below the threshold of band-to-band tunneling is generally caused by field-enhanced ionization of deep-level centers. We suggest that the process-induced sulfur centers and native defects such as EL2, HB2, HB5 centers initiate the front in Si and GaAs structures, respectively. In deep-level free structures the plane streamer front is triggered by Zener band-to-band tunneling.

Modern Korean literature as testimony to war : from the Korean War to the Vietnam War
Creators: name: Zur, Dafna
Publisher: name: University of British Columbia
Year: 2009

description: The Korean War was one of the most traumatic events in twentieth-century Korea. The war reshaped Korea's physical landscape and transformed its social and political structures. The war was, in origin, a civil conflict, a struggle between two opposing ideologies and a war that ended with an armistice that divided the Korean peninsula. These factors affected the way Korean writers expressed their experiences in it. The works I examine in my thesis are imbued with a strong sense of helplessness. Applying trauma theory used in psychoanalysis, I find that the helplessness is the result of a failure to deal with the traumatic events of the Korean War, a failure that I attribute to political and social causes. I examine the inability to resolve trauma in the works, and arrive at an understanding of the significance of an audience and a shared collective narrative in the resolution of private and public trauma. Between 1967 and 1975, South Korea was involved in the Vietnam War. During the two decades following the Korean War, political and social changes had taken place on the peninsula. Several works about the Vietnam War reflect Korea's turbulent changes. I show how the Vietnam War presented Koreans with the temporal and spatial opportunity to reflect upon the past, and paved the way to express unresolved trauma and explore forgotten memories. Literature about the Korean and Vietnam Wars contributes to our understanding of war and appoints the reader to the complex function of listener to experiences of trauma, hence allowing for a resolution of the authors' (and listeners') trauma. At the same time, reading literature as testimony is complicated when the reader takes into account the way texts are shaped by the political and social contexts surrounding their creation and the ways in which texts are read. I discuss how the anti-communist struggle as a collective narrative stifled the expressions of trauma and shaped the way memory is discussed in Korean War literature, and show how Vietnam War literature provides insights into how social and political changes allowed for the beginning of the resolution of Korean War trauma.

description: Beginning with the September 1986 contract, feeder cattle futures have been settled based on cash settlement rather than physical delivery. The effect that cash settlement will have on hedging risk for feeder cattle was estimated using Arkansas prices for 1977-86, but the results should be representative of other markets. For 600-700 pound steers and heifers, hedging risk is estimated to be lower for hedges placed in the new cash settlement contract. For steers and heifers weighing less than 600 pounds, hedging risk is estimated to be lower for the cash settlement contract for fall hedges, whereas hedging risk is estimated to increase for spring hedges.

description: Agribusiness graduate students should do problem-solving and take business courses to understand the environment in which they will practice their theory. The longer we wait to teach them application, the greater are the chances of losing our critical mass in terms of relevancy and political support. We can, and should, cultivate a broader range of agribusiness problems and clientele groups. We can effect change immediately by doing more agribusiness research. We can assure our long-run existence through a stronger political support base by educating our graduate students in the ways of firm-level agribusiness application.

 Diagnosis.— A species of Oligometra with segments of P2 mostly, or largely, longer than, or at least as long as, broad; distal ends of pinnular prismatic ridges more or less strongly produced, or with one or more spines (from A.H. Clark, 1947).
 Material examined.— None in this study. Specimens were previously collected at Bassas de Pedro by RIMS Investigator (A.H. Clark, 1947).
 Distribution.— From the Red Sea to Natal, South Africa, in the west to Tonga in the east, including Mauritius, Lakshadweep, Maldives, India (at least Tamil Nadu to Odisha), and New Caledonia, and from tropical Australia (Houtman Abrolhos, WA, to Tweed River, NSW) north to Hong Kong (A.H. Clark, 1947; A.M. Clark, 1972, 1974; Rowe & Gates, 1985; Messing, 1994). Depth range: shoreline to 91 m (? 183 m) (A.H. Clark, 1947).
 Remarks.— Although A.H. Clark (1947, p. 216) distinguished three of his eight “varieties” of O. serripinna as “true geographical races or subspecies”, and four as “localized varieties” of typical O. serripinna (= O. serripinna serripinna), all are considered subspecific rather than infra-subspecific under The International Code of Zoological Nomenclature articles 45.6.4 and 45.6.4.1 (ICZN, 1999). Most recent sources have ignored these taxa (e.g., A.M. Clark & Rowe, 1971; A.M. Clark, 1972; Rowe & Gates, 1985; Messing, 1994; Sastry, 2007), with a few exceptions (e.g., Oligometra serripinna occidentalis in A.M. Clark (1974) and Marshall & Rowe (1981); Oligometra chinensis A.H. Clark, 1918, in Kogo (1998)). The synonymy above includes only those subspecies recorded from the western Indian Ocean. All specimens previously collected in the Maldives and Lakshadweep have been identified as O. serripinna serripinna (A.H. Clark, 1947).

description: The dynamic structure of wheat acreage supply response is considerably more complex than previous studies have recognized. The distributed lag response is saw-toothed in its pattern, which is believed to eminate from the influence of summer fallow in crop rotations in the Great Plains. The acreage response elasticity estimate for the Great Plains at mean price was 1.3, and for the aggregate U.S. it was 1.5. For the Unites States, the proportion of long-run response experienced over the first five years from an increment to price was .24, .44, .70, .95, and. 99.

description: Introducing spin-polarized carriers in semiconductor lasers reveals an alternative path to realize room-temperature spintronic applications, beyond the usual magnetoresistive effects. Through carrier recombination, the angular momentum of the spin-polarized carriers is transferred to photons, thus leading to the circularly polarized emitted light. The intuition for the operation of such spin-lasers can be obtained from simple bucket and harmonic oscillator models, elucidating their steady-state and dynamic response, respectively. These lasers extend the functionalities of spintronic devices and exceed the performance of conventional (spin-unpolarized) lasers, including an order of magnitude faster modulation frequency. Surprisingly, this ultrafast operation relies on a short carrier spin relaxation time and a large anisotropy of the refractive index, both viewed as detrimental in spintronics and conventional lasers. Spin-lasers provide a platform to test novel concepts in spin devices and offer progress connected to the advances in more traditional areas of spintronics.

Approaching the knee -- balloon-borne observations of cosmic ray composition

description: Below the knee in the cosmic ray spectrum, balloon and spacecraft experiments offer the capability of direct composition and energy measurements on the primary particles. A major difficulty is obtaining enough exposure to extend the range of direct measurements sufficiently high in energy to permit overlap with ground-based observations. Presently, balloon and space measurements extend only up to ~100 TeV, well below the range of ground-based experiments. The prospect of Ultra-Long Duration Balloon missions offers the promise of multiple long flights that can build up exposure. The status of balloon measurements to measure the high energy proton and nuclear composition and spectrum is reviewed, and the statistical considerations involved in searching for a steepening in the spectrum are discussed. Given the very steeply falling spectrum, it appears unlikely that balloon experiments will be able to extend the range of direct measurements beyond 1000 TeV any time in the near future. Especially given the recent suggestions from KASCADE that the proton spectrum steepens only at 4000-5000 TeV, the chance of detecting the knee with direct measurements of protons to iron on balloons is not likely to occur without significant increases in the payload and flight duration capabilities of high altitude balloons.

description: Feeder cattle prices are determined by the interaction of many factors. This study uses 1986 and 1987 Kansas feeder cattle auction data to investigate the impact of a wide variety of physical characteristics, many of which have not been used in previous studies on feeder cattle prices. Unlike previous studies, this analysis explicitly incorporates changes in feeder cattle market fundamentals during the data collection period and also allows price differentials to vary by sex and weight. Weight, weight-squared, lot size, lot size-squared, health, muscling, frame size, condition, fill, breed, presence of horns, and time of sale are significant factors affecting feeder cattle prices on any given day. Several physical traits also exhibit different seasonal price impacts.

description: Strong variations in superconducting critical temperatures in different families of the cuprate perovskites, even with similar hole doping in their copper-oxygen planes, suggest the importance of lattice modulation effects. The one-dimensional incommensurate lattice modulation (ILM) of Bi_2Sr_2CaCu_2O_{8+y}, with the average atomic positions perturbed beyond the unit cell, offers an ideal test ground for studying the interplay between superconductivity and the long-range incommensurate lattice fluctuations. Here we report Scanning nano X-ray Diffraction (SnXRD) imaging of incommensurate lattice modulations in Bi_{2.1}Sr_{1.9}CaCu_{2.0}O_{8+δ} Van der Waals heterostructures of thicknesses down to two-unit cells. Using SnXRD, we probe that the long-range and short-range incommensurate lattice modulations in bulk sample surface with spatial resolution below 100 nm. We find that puddle-like domains of ILM of size uniformly evolving with dimensionality. In the 2-unit cell thin sample, it is observed that the wavevectors of the long- and short-range orders become anti-correlated with emerging spatial patterns having a directional gradient. The emerging patterns, originated by tiny tuning of lattice strain, induce static mesoscopic charge density waves. Our findings thus demonstrate that the strain can be used to tune and control the electromagnetic properties of two-dimensional high-temperature superconductors.

The Shell Model, the Renormalization Group and the Two-Body Interaction

description: The no-core shell model and the effective interaction $V_{{\rm low} k}$ can both be derived using the Lee-Suzuki projection operator formalism. The main difference between the two is the choice of basis states that define the model space. The effective interaction $V_{{\rm low} k}$ can also be derived using the renormalization group. That renormalization group derivation can be extended in a straight forward manner to also include the no-core shell model. In the nuclear matter limit the no-core shell model effective interaction in the two-body approximation reduces identically to $V_{{\rm low} k}$. The same considerations apply to the Bloch-Horowitz version of the shell model and the renormalization group treatment of two-body scattering by Birse, McGovern and Richardson.

description: A geometric distributed lag model was hypothesized as the structural relationship between purebred breeding bull price and economic variables determining the bull's value as a productive asset. Parameter estimates for the nonstochastic difference equation were obtained from a data sample including nineteen years of average price paid for yearling purebred Hereford bulls. Statistical results supported the hypotheses; expected bull price was responsive to calf price and cowherd inventory. An oscillating geometric adjustment pattern was found which reflected periodicity in bull replacement decisions. The general conclusion was that relevant information is rapidly incorporated into purebred bull market behavior and price adjusts quickly.

description: We analyze the energy terms corresponding to the spin-spin exchange and spin-random field coupling of the zero temperature random-field Ising model on the Bethe lattice driven by an external field with metastable dynamics. Exact results are calculated as a function of the standard deviation of the disorder and the coordination number z, and compared with numerical simulations on random graphs for z=4, for which a disorder-induced transition takes place.

description: Recent deep neural networks (DNNs) can easily overfit to biased training data with noisy labels. Label correction strategy is commonly used to alleviate this issue by designing a method to identity suspected noisy labels and then correct them. Current approaches to correcting corrupted labels usually need certain pre-defined label correction rules or manually preset hyper-parameters. These fixed settings make it hard to apply in practice since the accurate label correction usually related with the concrete problem, training data and the temporal information hidden in dynamic iterations of training process. To address this issue, we propose a meta-learning model which could estimate soft labels through meta-gradient descent step under the guidance of noise-free meta data. By viewing the label correction procedure as a meta-process and using a meta-learner to automatically correct labels, we could adaptively obtain rectified soft labels iteratively according to current training problems without manually preset hyper-parameters. Besides, our method is model-agnostic and we can combine it with any other existing model with ease. Comprehensive experiments substantiate the superiority of our method in both synthetic and real-world problems with noisy labels compared with current SOTA label correction strategies.

description: Using a chiral unitary approach for meson-baryon scattering in the strangeness zero sector, where the $N^*(1535)$ and $Δ^*(1700)$ resonances are dynamically generated, we study the reactions $γp \to π^0 ηp$ and $γp \to π^0 K^0 Σ^+$ at photon energies at which the final states are produced close to threshold. Among several reaction mechanisms, we find the most important is the excitation of the $Δ^*(1700)$ state which subsequently decays into a pseudoscalar meson and the $N^*(1535)$. Hence, the reaction provides useful information with which to test current theories of the dynamical generation of the low-lying $1/2^-$ and $3/2^-$ states. Predictions are made for cross sections and invariant mass distributions which can be compared with forthcoming experiments at ELSA.

description: The Hund coupling in multiorbital Hubbard systems induces spin freezing and associated Hund metal behavior. Using dynamical mean field theory, we explore the effect of local moment formation, spin and charge excitations on the entropy and specific heat of the three-orbital model. In particular, we demonstrate a substantial enhancement of the entropy in the spin-frozen metal phase at low temperatures, and peaks in the specific heat associated with the activation of spin and charge fluctuations at high temperature. We also clarify how these temperature scales depend on the interaction parameters and filling.

description: Time-resolved magneto-optical Kerr spectroscopy of ferromagnetic InMnAs reveals two distinct {\em demagnetization} processes -- fast ($<1$ ps) and slow ($\sim$100 ps). Both components diminish with increasing temperature and are absent above the Curie temperature. The fast component rapidly grows with pump power and saturates at high fluences ($>10$ mJ/cm$^2$); the saturation value indicates a {\em complete quenching} of ferromagnetism on a sub-picosecond time scale. We attribute this fast dynamics to spin heating through $p$-$d$ exchange interaction between photo-carriers and Mn ions while the $\sim$100 ps component is interpreted as spin-lattice relaxation.

Enteral feeding decreases gut apoptosis, gut permeability, and pulmonary inflammation during murine endotoxemia
Creators: name: Alscher, Kurt Thomas
Publisher: name: University of British Columbia
Year: 2009

description: Background: The systemic response to sepsis is associated with gut mucosal damage, increased permeability, and subsequently increased inflammation in distant organs. Enteral feeding may reduce mortality from multiple organ failure by maintaining the gut mucosal barrier, however the mechanism of this is unclear. We tested the hypothesis that endotoxemia is associated with increased gut apoptosis, increased gut permeability, and increased pulmonary inflammation. Furthermore, we postulate that enteral feeding ameliorates endotoxin's effect on these parameters. Methods: Four groups of 10 male CD-1 mice were studied: fed/sham, fasted/sham, fed/endotoxemic, fasted/endotoxemic. Fasted mice were denied food for 16 hours prior to injection of either saline or E. coli endotoxin. Fed animals received rodent chow throughout. Six hours post injection the gut and lungs were removed and frozen. We assessed gut apoptosis by measuring gut caspase 3, caspase 6 and PARP enzymatic activity. Gut permeability was quantified by measuring the transfer of fluorescein labeled dextran (FD-4) across the gut wall, and pulmonary inflammation was quantified by lung interleukin 6 (IL-6) and macrophage inflammatory protein-2 (MIP-2) ELISA. Results: 1) Apoptosis - After LPS injection, gut caspase 3 and 6 activity increased by 4.9 fold and 4.5 fold respectively (p<0.001); fed mice given endotoxin had 40% less caspase 3 activity and 20% less caspase 6 activity than fasted mice given endotoxin. Gut PARP activity was 15% higher in endotoxemic mice than controls (p<0.05) 2) Gut permeability - Endotoxemic mice had 44% (p<0.05) more FD-4 present in their serum than the sham mice; fed mice given endotoxin had 36% (p<0.05) less FD-4 than the fasted animals given endotoxin. 3) Pulmonary inflammation - After LPS injection, pulmonary IL-6 increased by 7.4 fold (p<0.001); fed animals had 40% less IL-6 than the fasted (p<0.05) mice given endotoxin. Lung MIP-2 increased by 292.1 fold (p<0.001) after LPS injection; fed animals had 35% less MIP-2 than their fasted counterparts within the endotoxemic group (p<0.05). Conclusions: Gut apoptosis, gut permeability, and pulmonary inflammation are increased during endotoxemia. Enteral feeding decreases gut apoptosis, and this is associated with improved gut barrier function and decreased pulmonary inflammation. Enteral feeding may decrease the systemic inflammatory response by maintaining gut mucosal function during endotoxemia.
