description: In this dissertation, I examine the efficacy of emulation strategies in both empirical and theoretical contexts, and thoroughly investigate one of the most important underlying factors in determining the effectiveness of emulation funds - the behavioural trading patterns of active fund managers. This research is driven by both increasing commercial interest in emulation products as they become more widespread (a number of providers including MLC, Russell Investments and NAB now offer portfolio emulation products), and a genuine academic interest in understanding the factors that drive their complex investment structures. Furthermore, the high-frequency analysis of active fund manager trading patterns is a significant topic in its own right, and represents an aspect of the fund manager performance literature that has previously been constricted by limited access to high granularity fund-level transactions data.
 In the first study, "Does Portfolio Emulation Outperform Its Target Funds?", I find that, while small but economically significant reductions to transaction costs do arise from emulation, the opportunity costs associated with altering the timing of trades significantly outweigh the benefits. The second study, "A Model of Emulation Funds", constructs a model of emulation fund cash flows. This model formalises the interaction between the marginal transaction costs savings and the performance impact of altered trade timing, enables forecasts of emulation fund performance based on forward-looking expectations, and allows numerical optimisation of key emulation fund parameters. The final study, "A Fourfold Pattern to the Art of Active Investing", examines the motivation behind observed trading patterns by mutual fund managers, and provides insight into how we can potentially design a more efficient emulation strategy.

description: Common abiotic stresses in rainfed rice areas like drought can occur at any phase of crop growth and may occur periodically. Variation in intensity and severity of drought requires the use of different rice varieties and different nutrient management strategies. This study evaluated the morphological and physiological response of contrasting rice cultivars (Rajalaxmi, IR64, and Sahbhagidhan) to various nutrient combinations under water sufficience and scarce conditions. Drought stress at vegetative stage significantly reduced tiller formation, dry matter remobilization,and photosynthesis, leading to around 41.6% yield reduction.The effect of drought stress was more evident in Rajlaxmi and IR64 by a yield reduction of 57.4% and 43.2% as against only 24.3% in Sahbhagidhan. The combined application of nutrients resulted in higher proline accumulation, chlorophyll and carbohydrate concentrations, and photosynthesis and antioxidant enzymes, ultimately better tolerance to drought. This is reflected in higher values of tolerance indices and low scores of leaf drying and leaf rolling, especially for Sahbhagidhan. The combined application of P, K, Ca, Zn, and Fe resulted in 52.9, 53.3, 48.9% higher yield over P or K application. Rice drought tolerance can be managed by combining breeding of drought tolerant high yielding varieties with proper application of fertilizer nutrients.

description: Multiple codes are available to derive atmospheric parameters and individual chemical abundances from high-resolution spectra of AFGKM stars. Almost all spectroscopists have their own preferences regarding which code and method to use. But the intrinsic differences between codes and methods lead to complex systematics that depend on multiple variables such as the selected spectral regions and the radiative transfer code used. I expand iSpec, a popular open-source spectroscopic tool, to support the most well-known radiative transfer codes and assess their similarities and biases when using multiple set-ups based on the equivalent-width method and the synthetic spectral-fitting technique (interpolating from a pre-computed grid of spectra or synthesizing with interpolated model atmospheres). This work shows that systematic differences on atmospheric parameters and abundances between most of the codes can be reduced when using the same method and executing a careful spectral feature selection. However, it may not be possible to ignore the remaining differences, depending on the particular case and the required precision. Regarding methods, equivalent-width-based and spectrum-fitting analyses exhibit large differences that are caused by their intrinsic differences, which is significant given the popularity of these two methods. The results help to identify the key caveats of modern spectroscopy that all scientists should be aware of before trusting their own results or being tempted to combine atmospheric parameters and abundances from the literature.

Population health impacts of STI surveillance: a quality improvement project to improve care efficiency and compliance with State reporting requirements
Creators: name: Adeniji, Aishat 'R

Year: 2021

description: Background- Infectious disease surveillance can inform public health officers on disease morphology, management approaches, disease trends, and disease burden within a demographic. Adequate disease surveillance can also inform funding and resource allocation to mitigate the risk of exposure/community outbreaks. This project was conducted to determine whether the adoption of a disease surveillance workflow and implementing an evidence-based clinical management guideline could enhance clinician attitude and compliance with treatment guidelines. Simultaneously, improving adherence to state reporting requirements to improve patient outcomes in an urgent care clinic ultimately. Method- Full-time and part-time clinical staff (Physicians, Nurse Practitioners. Physician Assistants, Medical Scribe, and Medical Assistants) at an inner-city urgent care clinic were educated on a newly implemented disease surveillance workflow. A data abstraction tool was used to extract the independent and dependent variables in the study. Data collection spanned over 8 weeks before the clinical staff training and implementation of the disease surveillance workflow and 8 weeks after the clinical staff training. The independent variables used in this study were individual patient record on STI, which included the following 11 care component items; sexual risk assessment, reoccurrence, problem list, history, contact tracing, HIV status, medication reconciliation, Preexposure Prophylactic (PrEP), counseling, linkage to care, and STI testing. The dependent variable is the completion rate of the Department of Health (DOH) STI confidential report and its attachment to the electronic chart. Results- Descriptive statistics were used to analyze findings from 78 de-identified charts. Of the 40 charts reviewed before the implementation of the disease surveillance workflow, none of the charts recorded information on PrEP/EPT offering or completion of the New Jersey Department of Health (DOH) STI confidential report. Subsequently, 38 de-identified charts reviewed after implementing the workflow showed improved clinician attitude towards recommending linkage to care, offering PrEP, consistent STI management, and adherence to state reporting requirements. Findings from collected data showed that the post-implementation group's components of care score was higher than the pre-implementation group (Pre-implementation = n=40, Post-implementation = n=38). A Mann-Whitney test indicated that this finding was statistically significant, U = 289.50, z = -4.88, p

description: We propose an optimal operation control strategy for an electro-thermal microgrid. Compared to existing work, our approach increases flexibility by operating the thermal network with variable flow temperatures and in that way explicitly exploits its inherent storage capacities. To this end, the microgrid is represented by a multi-layer network composed of an electrical and a thermal layer. We show that the system behavior can be represented by a discrete-time state model derived from DC power flow approximations and 1d incompressible Euler equations. Both layers are interconnected via heat pumps. By combining this model with desired operating objectives and constraints, we obtain a constrained convex optimization problem. This is used to derive a model predictive control scheme for the optimal operation of electro-thermal microgrids. The performance of the proposed operation control algorithm is demonstrated in a numerical case study.

description: We present experimental phase function and degree of linear polarization curves for seven samples of cometary dust analogues namely: ground pieces of Allende, DaG521, FRO95002 and FRO99040 meteorites, Mg-rich olivine and pyroxene, and a sample of organic tholins. The experimental curves have been obtained at the IAA Cosmic Dust Laboratory at a wavelength of 520 nm covering a phase angle range from 3° to 175°. We also provide values of the backscattering enhancement (BCE) for our cometary analogue samples. The final goal of this work is to compare our experimental curves with observational data of comets and asteroids to better constrain the nature of cometary and asteroidal dust grains. All measured phase functions present the typical behavior for μm-sized cosmic dust grains. Direct comparison with data provided by the OSIRIS/Rosetta camera for comet 67P Churyumov-Gerasimenko reveals significant differences and supports the idea of a coma dominated by big chunks, larger than one micrometer. The polarization curves are qualitatively similar to ground-based observations of comets and asteroids. The position of the inversion polarization angle seems to be dependent on the composition of the grains.We find opposite dependence of the maximum of the polarization curve for grains sizes in the Rayleigh-resonance and geometric optics domains, respectively.

description: Maternal obese environment has been reported to induce oxidative stress and meiotic defects in oocytes, however the underlying molecular mechanism remains unclear. Here, using mice fed a high fat diet (HFD) as an obesity model, we first detected enhanced reactive oxygen species (ROS) content and reduced Sirt3 expression in HFD oocytes. We further observed that specific depletion of Sirt3 in control oocytes elevates ROS levels while Sirt3 overexpression attenuates ROS production in HFD oocytes, with significant suppression of spindle disorganization and chromosome misalignment phenotypes that have been reported in the obesity model. Candidate screening revealed that the acetylation status of lysine 68 on superoxide dismutase (SOD2K68) is dependent on Sirt3 deacetylase activity in oocytes, and acetylation-mimetic mutant SOD2K68Q results in almost threefold increase in intracellular ROS. Moreover, we found that acetylation levels of SOD2K68 are increased by ∼80% in HFD oocytes and importantly, that the non-acetylatable-mimetic mutant SOD2K68R is capable of partially rescuing their deficient phenotypes. Together, our data identify Sirt3 as an important player in modulating ROS homeostasis during oocyte development, and indicate that Sirt3-dependent deacetylation of SOD2 plays a protective role against oxidative stress and meiotic defects in oocytes under maternal obese conditions.

Transmission Spectra as Diagnostics of Extrasolar Giant Planet Atmospheres

Year: 2001
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Atmospheres of transiting extrasolar giant planets (EGPs) such as HD 209458 b must impose features on the spectra of their parent stars during transits; these features contain information about the physical conditions and chemical composition of the atmospheres. The most convenient observational index showing these features is the ``spectrum ratio'', defined as the wavelength-dependent ratio of spectra taken in and out of transit. I describe a model that estimates this ratio and its dependence upon parameters of the planetary atmosphere, including its cloud structure, temperature, chemical composition, and wind fields. For giant planets in close orbits, the depths of atomic and molecular features in the spectrum ratio may be as large as 0.001. Observations in visible and near-IR wavelengths using existing and planned spectrographs should be adequate to detect these features, and to provide some diagnostics of the conditions within the planetary atmosphere. I give numerous examples of such diagnostics, and I discuss their practicality.

description: Using the density-matrix renormalization group technique, we study a one-dimensional spin-$\frac{1}{2}$ Heisenberg chain consisting of coupled tetramers as an effective spin model for copper vanadate CuInVO$_5$. We obtain the ground-state phase diagram as a function of intra-tetramer and inter-tetramer exchange interactions, exhibiting two multimerized valence-bond-solid (VBS) phases : one is characterized by the formation of tetramer-singlet units; the other by the formation of dimer-singlet pairs. We show that the finite spin gaps in both the VBS phases smoothly vanish at the phase boundary: a second order phase transition defining a quantum critical point (QCP). The phase boundary is also captured by the fact that the central charge is unity at the phase boundary and zero otherwise in the thermodynamic limit. We further demonstrate that the experimental magnetization curve (which starts increasing with zero or tiny field) can be reasonably explained only by assuming the exchange parameters of CuInVO$_5$ to be very close to the phase boundary. Thus, we argue that CuInVO$_5$ may be a first example material which at ambient pressure stands near a QCP between two VBS phases. By varying the balance of exchange interactions with pressure, a transition from Néel to either of the VBS phases could be observed.

description: The bright radio source S5 0716+714, that is usually classified as BL Lac object, is one of the most intensively studied. S5 0716+714 demonstrates extremely peculiar properties such as the shortest time-scale of optical and polarimetric variations observed in blazars. In given paper, the results of 9-hour polarimetric monitoring of S5 0716+714 with the $\sim$70-second resolution, carried out by the 6-m telescope BTA of SAO RAS, are presented. The observation data analysis reveals the variability both in total and polarized light on the 1-1.5-hour time-scale. Since polarization is generated by plasma motion in the magnetic field, the variations of polarization vector are bounded with the magnetic field configuration and the average time-scales specify the size of the emitting region, unresolved directly. We suggest a processed numerically model of polarization in the jet with the precessing helical magnetic field. Fitting the model discovers that observed short-term variations with the complicated trajectory of polarization vector could be induced by the magnetic field precession with the period $T \approx 15$ days.

description: The Main Map presented in this paper is the result of intensive fieldwork and mapping of 43 rural communities of the Pátzcuaro and Zirahuén basins in central-western Mexico. It shows the presence of handmade-tortilla workshops and considers the natural resources they demand but also their social, economic and cultural significance in the region. An in-depth survey of 111 Hand Made Tortilla Workshops gave detailed information of tortilla production, type of maize and fuelwood volume demanded in this activity. Traditional tortilla production contributes to the conservation of native maize and indigenous agriculture, and it promotes local and traditional food systems. However, it also represents a challenge given that many of these handmade tortilla workshops use open fire stoves which have negative implications regarding health, environment and pollution in rural livelihoods. This map serves as a platform for local and regional actions within a program involved in eco-technologies and sustainable livelihoods.

description: We numerically calculate, at the edge of chaos, the time evolution of the nonextensive entropic form $S_q \equiv [1-\sum_{i=1}^W p_i^q]/[q-1]$ (with $S_1=-\sum_{i=1}^Wp_i \ln p_i$) for two families of one-dimensional dissipative maps, namely a logistic- and a periodic-like with arbitrary inflexion $z$ at their maximum. At $t=0$ we choose $N$ initial conditions inside one of the $W$ small windows in which the accessible phase space is partitioned; to neutralize large fluctuations we conveniently average over a large amount of initial windows. We verify that one and only one value $q^*<1$ exists such that the $\lim_{t\to\infty} \lim_{W\to\infty} \lim_{N\to\infty} S_q(t)/t$ is {\it finite}, {\it thus generalizing the (ensemble version of) Kolmogorov-Sinai entropy} (which corresponds to $q^*=1$ in the present formalism). This special, $z$-dependent, value $q^*$ numerically coincides, {\it for both families of maps and all $z$}, with the one previously found through two other independent procedures (sensitivity to the initial conditions and multifractal $f(α)$ function).

description: This study was designed to establish the most effective solvent/technique for extracting antioxidant phytoconstituents from leaves and flower buds of Inula viscosa (L.) Aiton (Asteraceae) grown wild in Morocco. Maceration and hot extraction with methanol or water and Soxhlet ethanol extraction were utilized. The antioxidant potential was evaluated in vitro by DPPH, reducing power, and ferrous ions chelating activity assays. I. viscosa leaf and flower bud extracts displayed the strongest effect in the DPPH test, being the Soxhlet ethanol the most active ones (IC50 = 54.24 ± 0.21 μg/mL and 39.77 ± 0.23 μg/mL); thus, they were selected for further investigations. The antimicrobial efficacy of the Soxhlet ethanol extracts against ATCC and food isolates strains was assayed; the leaf extract showed the best activity, and Candida albicans was the most sensitive strain (MIC = 125 µg/mL). The extracts resulted non-toxic against Artemia salina. Among the phenolics characterised by HPLC-PDA-ESI-MS, hispidulin hexoside, patuletin and spinacetin were identified for the first time.

description: We investigate classically non-singular bounces caused by dark energy. In the presence of positive spatial curvature, vacuum energy, either in the form of a cosmological constant or a scalar field potential, allows for an open set of initial conditions leading to non-singular bounces, without any violation of the null energy condition. We study anisotropic Bianchi IX cosmologies, and demonstrate that they can even have multiple bounces, accompanied by intricate evolutions of the anisotropies that provide a non-singular analogue of mixmaster crunches. The relation of these solutions to more complete cosmological models, as well as to the recently proposed swampland criteria, are briefly discussed.

Comment on ``Superconducting PrBa_2Cu_3O_x''

description: Recently, Zou et al. (Phys. Rev. Lett. 80, 1074, 1998) reported the observation of bulk superconductivity (SC) for a PrBa_2Cu_3O_x (Pr123) single crystal grown by the traveling-solvent floating zone (TSFZ) method. The aim of this Comment is to show the inconsistency of the value of effective magnetic moment μ_{eff} reported by Zou et al. (2.92μ_B) with their magnetic susceptibility data. The estimation made directly from their data points gives a considerably smaller value of μ_{eff}=2.09μ_B. At the same time the values of mu_{eff}=2.9μ_B and 3.1μ_B were obtained for our Pr123 single crystals grown by flux method for H||ab-plane and H||c-axis, respectively. This suggests that Pr occupies only about a half of the RE sites in TSFZ crystal. The other half of the RE sites is occupied most probably by the nonmagnetic Ba. Noteworthy, SC with T_c=43 K was observed earlier for Pr_{0.5}Ca_{0.5}Ba_2Cu_3O_{7-y} thin films. Ba^{2+} has a larger ionic radius than Pr^{3+} and so the substitution of Ba for Pr could give a natural explanation not only for the SC in TSFZ Pr123 but also for the elongation of the distance between the CuO_2 planes observed by Zou et al.

description: An amino-modified multiwalled carbon nanotube (MWCNT) solid-phase extraction-based hydrophilic interaction liquid chromatography–tandem mass spectrometry (HILIC–MS/MS) method was developed for simultaneous determination of 13 paralytic shellfish toxins (PSTs) in bivalve mollusks. Shellfish samples were extracted with 1% acetic acid followed by cleanup using optimized MWCNT-NH2 based solid-phase extraction. Absorbed PSTs were eluted with 2 mL 1% acetic acid–acetonitrile (70/30, v/v). The separation was performed on a Waters BEH Amide column within 7.5 min utilizing 0.1% formic acid–acetonitrile and 2 mM ammonium acetate containing 0.1% formic acid as the mobile phase. The analytes were quantified by matrix-matched external standard curves with correlation coefficients® exceeding 0.997 acquired in multiple reaction-monitoring mode. The limits of detection and quantitation in shellfish samples were from 2.76 to 9.8 μg/kg and 9.11 to 39.3 μg/kg, respectively. Recoveries at three spiked levels ranged from 71.4% to 97.8% with relative standard deviations less than 12.6%. The developed method was satisfactorily applied to the analysis of shellfish.

description: The initial results of a millimeter (CO) survey of infrared-excess, optically-selected quasars from the Palomar-Green (PG) Bright Quasar Survey (BQS) with redshifts in the range 0.04 < z < 0.17 are presented. These observations represent the first step towards establishing with a complete sample whether or not quasi-stellar objects (QSOs) reside in molecular gas-rich galaxies, as well as towards determining how the infrared and molecular gas properties of QSOs compare with those of ultraluminous infrared galaxies (ULIGs), which are a possible evolutionary precursor of QSOs. The sample consists of QSOs having absolute blue magnitudes, M_B 0.36, where the contribution to the bolometric luminosity of infrared thermal dust emission for all PG QSOs is typically 20--40%. Six out of 10 of the QSOs observed are detected in the CO(1-0) emission line; two detections confirm previous, less sensitive detections of CO(1-0) in PG 1613+658 and PG 0838+770, and four additional QSOs are detected for the first time (PG 1119+120, PG 1351+640, PG 1415+451, and PG 1440+356). These six detections, plus two previous detections of CO in IZw1 and Mrk 1014, bring the total number of 0.04 < z < 0.17 infrared-excess PG QSOs detected in CO to date to eight, and provide possible evidence that, in addition to fueling star formation, molecular gas may also serve as a primary source of fuel for QSO activity...

On the power of one pure steered state for EPR-steering with a pair of qubits

description: As originally introduced, the EPR phenomenon was the ability of one party (Alice) to steer, by her choice between two measurement settings, the quantum system of another party (Bob) into two distinct ensembles of pure states. As later formalized as a quantum information task, EPR-steering can be shown even when the distinct ensembles comprise mixed states. Consider the scenario where Alice and Bob each have a qubit and Alice performs dichotomic projective measurements. In this case, the states in the ensembles to which she can steer form the surface of an ellipsoid ${\cal E}$ in Bob's Bloch ball. Further, let the steering ellipsoid ${\cal E}$ have nonzero volume. It has previously been shown that if Alice's first measurement setting yields an ensemble comprising two pure states, then this, plus any one other measurement setting, will demonstrate EPR-steering. Here we consider what one can say if the ensemble from Alice's first setting contains only one pure state $\mathsf{p}\in{\cal E}$, occurring with probability $p_\mathsf{p}$. Using projective geometry, we derive the necessary and sufficient condition analytically for Alice to be able to demonstrate EPR-steering of Bob's state using this and some second setting, when the two ensembles from these lie in a given plane. Based on this, we show that, for a given ${\cal E}$, if $p_\mathsf{p}$ is high enough [$p_{\sf p} > p_{\rm max}^{\cal E} \in [0,1)$] then any distinct second setting by Alice is sufficient to demonstrate EPR-steering. Similarly we derive a $p_{\rm min}^{\cal E}$ such that $p_\mathsf{p}>p_{\rm min}^{\cal E}$ is necessary for Alice to demonstrate EPR-steering using only the first setting and some other setting. Moreover, the expressions we derive are tight; for spherical steering ellipsoids, the bounds coincide: $p_{\rm max}^{\cal E} = p_{\rm min}^{\cal E}$.

description: We analyze the onset of incommensurabilities around the VBS point of the S=1 bilinear-biquadratic model. We propose a simple effective field theory which is capable of reproducing all known properties of the commensurate-incommensurate transition at the disorder point $θ_{\rm vbs}$. Moreover, the theory predicts another special point $θ_{\rm disp}$, distinct from the VBS point, where the Haldane gap behaves singularly. The ground state energy density is an analytic function of the model parameters everywhere, thus we do not have phase transitions in the conventional sense.

description: We discuss baryon stopping in the Color Glass Condensate description of high energy scattering. We consider the scattering of a distribution of valence quarks on an ultra-relativistic sheet of colored charge. We compute the distribution of scattered quarks from a composite projectile, and calculate the baryon currents before and after the collisions and on an event by event basis. We obtain simple analytic estimates of the baryon number compression and rapidity shifts, which in the idealized case of plane wave scattering, produce results that agree with considerations of Anishetty-Koehler-McLerran.

description: Creating complex flux configurations by superposing a dc current or magnetic field onto the ac current in a type II superconducting tape should lead to a variety of peculiar behaviors. An example is the appearance of the Clem valley, a minimum in the ac losses as a function of the dc bias amplitude, which has been theoretically studied by LeBlanc et al., in the continuation of Clem's calculations. These situations have been investigated by applying a dc current to a silver-gold sheathed Bi-2223 tape at 77 K (critical current 29 A), in addition to the usual ac transport current. The ac losses were measured by the null calorimetric method to ensure that the total losses were being accounted for. These were recorded for different values of the ac and dc currents, leading to the observation of two different behaviors depending on the ac current. Our revelation of the Clem valley is, to our knowledge, the first experimental validation of this phenomenon in high temperature superconductors, and may provide a simple way of reducing the ac loss in industrial applications of these materials.

description: We describe an L-band photometric survey of 0.5 square deg of the Cha I dark cloud. The survey has a completeness limit of L < 11.0. Our survey detects 124 sources, including all known pre-main sequence stars with L < 11. The fraction of sources with near-IR excess emission is 58% +- 4% for K = 9-11. Cha I sources have bluer H-K and K-L colors than pre-main sequence stars in Taurus-Auriga. These sources also have a strong correlation between EW(H-alpha) and K-L. Stars with K-L < 0.6 have weak H-alpha emission; stars with K-L > 0.6 have strong H-alpha emission. Because many Cha I sources are heavily reddened, this division between weak emission T Tauri stars and classical T Tauri stars occurs at a redder K-L than in Taurus-Auriga.
