description: This paper addresses the difficult problem of deciding where to refine the resolution of adaptive discretizations for solving continuous time-and-space deterministic optimal control problems. We introduce two measures, influence and variance of a Markov chain. Influence measures the extent to which changes of some state affect the value function at other states. Variance measures the heterogeneity of the future cumulated active rewards (whose mean is the value function). We combine these two measures to derive a nonlocal efficient splitting criterion that takes into account the impact of a state on other states when deciding whether to split. We illustrate this method on the non-linear, two dimensional “Car on the Hill” and the 4d “space-shuttle” and “airplane-meeting” control problems

description: A re-evaluation of the Molten Salt Breeder Reactor concept has revealed problems related to its safety and to the complexity of the reprocessing considered. A reflection is carried out anew in view of finding innovative solutions leading to the Thorium Molten Salt Reactor concept. Several main constraints are established and serve as guides to parametric evaluations. These then give an understanding of the influence of important core parameters on the reactor's operation. The aim of this paper is to discuss this vast research domain and to single out the Molten Salt Reactor configurations that deserve further evaluation.

description: Coastal eutrophication resulting from nutrient over-enrichment plagues coastal waterways worldwide. In addition to dissolved inorganic N, many marine microbes, including phytoplankton, have the capacity to use certain dissolved organic nitrogen (DON) compounds. However, while we know that many specific DON compounds are labile, the bulk of the DON pool in nature is uncharacterized. The bioavailability of DON to estuarine microbes currently remains unclear.

It is becoming evident that natural phytoplankton assemblages in estuarine waters are capable of using both inorganic and organic N compounds for growth, both of which are present in anthropogenic point and non-point source discharges. Methods for assessing the bioavailability of diverse and mostly uncharacterized suite of organic N compounds are not yet established, but determination of natural community response to anthropogenic nutrient loading is critical for developing goals to reduce coastal eutrophication.

This study was designed to compare the bioavailability and impact of three different N sources to natural estuarine community assemblages. Anthropogenic N loads include nitrate and urea from fertilizers and other waste streams as well as other uncharacterized organic N, such as that found in treated wastewater effluents. Here, we amended natural estuarine communities with nitrate, urea, or concentrated WWTP effluent (referred to as C-WTEN in some tables) to compare the relative impacts of the different N compounds. Results from this study should be useful to managers as they target specific nutrient reductions.

I found that both inorganic and organic forms of nitrogen are bioavailable to the algal community and all forms of N tested were rapidly taken up within the first 4 hours after their addition to incubation bottles. Phytoplankton cell abundance increased within all N treatments and there was a shift in the composition of phytoplankton community structure based on whether organic or inorganic N was the dominant form of N provided. Both chlorophyll a concentrations and primary production levels in treatment bottles increased relative to control incubations for all N compounds tested. These results suggest that a reduction in total N loads, rather than specific N sources, is necessary to be protective of environmental quality and excess algal production.

description: Correct estimates of import demand elasticities are essential for measuring the gains from trade and predicting the impact of trade policies. We show that esti- mates of import demand elasticities hinge critically on whether they are derived using trade quantities or trade values, and this dierence is due to properties of the estimators. Using partial identication methods, we show theoretically that the upper bound on the set of plausible estimates is lower when using traded quantities, compared to the standard approach using trade values. Our proposed method using traded quantities leads to smaller point estimates of the import demand elasticities for many goods and imply larger gains from trade compared to estimates based on trade values.

description: Controlling light at the level of individual photons has led to advances in fields ranging from quantum information and precision sensing to fundamental tests of quantum mechanics. A central development that followed the advent of single photon sources was the observation of the Hong-Ou- Mandel (HOM) effect, a novel two-photon path interference phenomenon experienced by indistinguishable photons. The effect is now a central technique in the field of quantum optics, harnessed for a variety of applications such as diagnosing single photon sources and creating probabilistic entanglement in linear quantum computing. Recently, several distinct experiments using atomic sources have realized the requisite control to observe and exploit Hong-Ou-Mandel interference of atoms. This article provides a summary of this phenomenon and discusses some of its implications for atomic systems. Transitioning from the domain of photons to atoms opens new perspectives on fundamental concepts, such as the classification of entanglement of identical particles. It aids in the design of novel probes of quantities such as entanglement entropy by combining well established tools of AMO physics - unity single-atom detection, tunable interactions, and scalability - with the Hong-Ou-Mandel interference. Furthermore, it is now possible for established protocols in the photon community, such as measurement-induced entanglement, to be employed in atomic experiments that possess deterministic single-particle production and detection. Hence, the realization of the HOM effect with atoms represents a productive union of central ideas in quantum control of atoms and photons.

The Pulse Scale Conjecture and the Case of BATSE Trigger 2193

Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The pulses that compose gamma-ray bursts (GRBs) are hypothesized to have the same shape at all energies, differing only by scale factors in time and amplitude. This "Pulse Scale Conjecture" is confirmed here between energy channels of the dominant pulse in GRB 930214c (BATSE trigger 2193), the single most fluent single-pulsed GRB that occurred before May 1998. Furthermore, pulses are hypothesized to start at the same time independent of energy. This "Pulse Start Conjecture" is also confirmed in GRB 930214c. Analysis of GRB 930214c also shows that, in general, higher energy channels show shorter temporal scale factors. Over the energy range 100 KeV - 1 MeV, it is found that the temporal scale factors between a pulse measured at different energies are related to that energy by a power law, possibly indicating a simple relativistic mechanism is at work. To test robustness, the Pulse Start and Pulse Scale Conjectures were also tested on the four next most fluent single-pulse GRBs. Three of the four clearly passed, with a second smaller pulse possibly confounding the discrepant test. Models where the pulse rise and decay are created by different phenomena do not typically predict pulses that satisfy both the Pulse Start Conjecture and the Pulse Scale Conjecture, unless both processes are seen to undergo common time dilation.

description: Excerpts from the report Preface: This report is one of a group dealing with Class III milk pricing in the New York-New Jersey milkshed. Particular emphasis is given to factors affecting the market for Class III products and to the decisions which handlers make about the form in which they will dispose of Class III milk. This report deals with the extent to which changes in output of the major products of Class III milk were associated with changes in margins for these products in the 5 or 10 years ending with 1957. It also covers the results of interviews with officials of many of the firms that handled Class III milk. During these interviews, the officials were asked about the considerations that affected their decisions on how they use this milk. The questions concerned such topics as each firm's preferences among the products it was equipped to produce and limitations on the extent to which the firm could adjust its output to take advantage of shifts in profitability among products.

Cultivating perceptions: exploring the influence of news media on perceived polarization
Creators: name: Wang, Luxuan
Publisher: name: No Publisher Supplied
Year: 2024

description: The past decade has witnessed growing polarization in American society, with the mass public developing stronger perceptions of divisions along political party lines. A primary goal of this research is to understand where people’s perceptions of polarization come from. Past research investigating the perceived polarization phenomenon spans diverse disciplines in the social sciences and has uncovered psychological foundations and features of the contemporary political climate to explain its existence. However, the scholarship has largely underplayed the role of the media landscape, characterized by a structural overemphasis on partisan conflicts and extreme portrayals in political news coverage, in shaping these perceptions. Recognizing the potential influence of contention-oriented news coverage on individuals’ perceptions of politics, this dissertation investigates the relationship between news media usage and perceived polarization. In doing so, it expands the understanding of the processes and conditions under which media shape perceptions of political polarization, while simultaneously underscoring the importance of taking a holistic view to diagnose the polarizing impact of news media in today’s landscape. To this end, the dissertation conducts a multifaceted empirical assessment of the relationship between broad media uses from different outlets, perceived polarization, and actual polarization. It also delves into various types of media messages centered on political contention and the underlying mechanisms of emotions in explaining media effects on perceived polarization. The results indicate that both partisan news consumption and general political news consumption are significantly associated with heightened perceptions of partisan divisions between political leaders, which can, in turn, translate into actual ideological extremity and increased partisan animosity. Analyses further suggest the existence of mutual influences among political news consumption, perceived polarization, and actual polarization. While centrist news use was not found to be associated with increased perceived polarization, the findings of the dissertation provide compelling evidence that various narratives of political contention, including neutral coverage of partisan conflict, can all intensify perceived division and strengthen individuals’ meta-perception of issue extremity. Although the analysis yielded mixed results about the mediating role of emotional reactions in explaining media effects on perceived polarization, the overall research offers robust evidence underscoring how the systematic overemphasis on political contention in news media exacerbates individuals’ perceptions of polarization. Remarkably, this influence speaks to a broad public, including those with relatively moderate political views.

description: In this note we explore a modified theory of gravitation that is not based on the least action principle, but on a natural generalization of the original Einstein's field equations. This approach leads to the non-covariant conservation of the stress-energy tensor, a feature shared with other Lagrangian theories of gravity such as the $f(R,T)$ case. We consider the cosmological implications of a pair of particular models within this theory, and we show that they have some interesting properties. In particular, for some of the studied models we find that the density is bounded from above, and cannot exceed a maximum value that depends on certain physical constants. In the last part of the work we compare the theory to the $f(R,T)$ case and show that they lead to different predictions for the motion of test particles.

Q^2-Dependence of the Neutron Spin Structure Function g_2^n at Low Q^2
Creators: name: Kramer, K.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Nuclear Experiment (nucl-ex)

description: We present the first measurement of the Q^2-dependence of the neutron spin structure function g_2^n at five kinematic points covering 0.57 (GeV/c)^2 <= Q^2 <= 1.34 (GeV/c)^2 at x~0.2. Though the naive quark-parton model predicts g_2=0, non-zero values for g_2 occur in more realistic models of the nucleon which include quark-gluon correlations, finite quark masses or orbital angular momentum. When scattering from a non-interacting quark, $g_2^n$ can be predicted using next-to-leading order fits to world data for g_1^n. Deviations from this prediction provide an opportunity to examine QCD dynamics in nucleon structure. Our results show a positive deviation from this prediction at lower Q^2, indicating that contributions such as quark-gluon interactions may be important. Precision data obtained for g_1^n are consistent with next-to-leading order fits to world data.

description: Data-driven approaches for learning dynamic models for Bayesian filtering often try to maximize the data likelihood given parametric forms for the transition and observation models. However, this objective is usually nonconvex in the parametrization and can only be locally optimized. Furthermore, learning algorithms typically do not provide performance guarantees on the desired Bayesian filtering task. In this work, we propose using inference machines to directly optimize the filtering performance. Our procedure is capable of learning partially-observable systems when the state space is either unknown or known in advance. To accomplish this, we adapt PREDICTIVE STATE INFERENCE MACHINES (PSIMS) by introducing the concept of hints, which incorporate prior knowledge of the state space to accompany the predictive state representation. This allows PSIM to be applied to the larger class of filtering problems which require prediction of a specific parameter or partial component of state. Our PSIM+HINTS adaptation enjoys theoretical advantages similar to the original PSIM algorithm, and we showcase its performance on a variety of robotics filtering problems.

description: The problem of determining the effects of the surrounding plasma on nuclear reaction rates in stars is formulated ab initio, using the techniques of quantum statistical mechanics. We derive a result that expresses the complete effects of Coulomb barrier penetration and of the influence of the surrounding plasma in terms of matrix elements of well defined operators. We find that possible "dynamical screening" effects that have been discussed in the literature are absent. The form of our results suggests that an approach that relies on numerical calculations of the correlation functions in a classical Coulomb gas, followed by construction of an effective two body potential and a quantum barrier penetration calculation, will miss physics that is as important as the physics that it includes.

description: There is a growing interest in analysing the diusion of agricultural insurance, seen as an eective tool for managing farm risks. Much atten- tion has been dedicated to understanding the scarce adoption rate despite high levels of subsidization and policy support. In this paper, we anal- yse an aspect that seems to have been partially overlooked: the potential competing nature between insurance and other risk management tools. We consider hail as a single source weather shock and analyse the po- tential competing eect of anti-hail nets over insurance as instruments to cope with this shock by presenting a simple theoretical model that is rooted into expected utility theory. After describing the basic model, we perform some comparative static analysis to identify the role of individual elements that are shaping farmers' decisions. From this exercise it results that the worth of anti-hail nets compared to insurance is an increasing function of the overall risk of hail damages, of the farmers' level of risk aversion and of the worth of the agricultural output. Finally, we develop a simulation model using data related to apple pro- duction in South Tyrol, a Northern-Italian province with a relatively high risk of hail. The model generally conrms the results of the comparative static analysis and it shows that, in this region, anti-hail nets are often superior than insurance in expected utility terms.

description: Excerpts from the report: Of all consumer expenditures for food, approximately 25 percent are for prepared foods purchased in away-from-home eating establishments; this is an increase of nearly one-third from 20 years ago. Therefore, the study of costs and margins for food served in eating establishments is within the general scope of studies of costs and margins for farm products. This is a report of one such study: the costs and margins for serving beverages in the employee food services operated in an office building (in-plant food service). The term "food cost" used in this report has the same meaning as the more general accounting terms, "cost of goods sold," "raw materials cost," or "cost of ingredients." The purpose of this study was twofold: (1) To determine the costs and margins for serving beverages in the employee food facilities operated in an office building; (2) to examine certain merchandising and pricing principles in the light of costs and margins as well as other factors that determine pricing policies.

description: We present a novel method for enforcing nonlinear inequality constraints in the estimation of a high degree of freedom robotic system within a Kalman filter. Our constrained Kalman filtering technique is based on a new concept, which we call uncertainty projection, that projects the portion of the uncertainty ellipsoid that does not satisfy the constraint onto the constraint surface. A new PDF is then generated with an efficient update procedure that is guaranteed to reduce the uncertainty of the system. The application we have targeted for this work is the localization and automatic registration of a robotic surgical probe relative to preoperative images during image-guided surgery. We demonstrate the feasibility of our constrained filtering approach with data collected from an experiment involving a surgical robot navigating on the epicardial surface of a porcine heart.

description: We present a study of available Hubble Space Telescope (HST) spectroscopic and imaging observations of the low ionization nuclear emission line region (LINER) galaxy NGC 1052. The WFPC2 imagery clearly differentiates extended nebular Halpha emission from that of the compact core. Faint Object Spectrograph (FOS) observations provide a full set of optical and UV data (1200-6800 Angstroms). These spectral data sample the innermost region (0."86 x 0."86 ~ 82pc x 82pc) and exclude the extended Halpha emission seen in the WFPC2 image. The derived emission line fluxes allow a detailed analysis of the physical conditions within the nucleus. The measured flux ratio for Halpha/Hbeta, F{Halpha}/F{Hbeta}=4.53, indicates substantial intrinsic reddening, E(B-V)=0.42, for the nuclear nebular emission. This is the first finding of a large extinction of the nuclear emission line fluxes in NGC 1052. If the central ionizing continuum is assumed to be attenuated by a comparable amount, then the emission line fluxes can be reproduced well by a simple photoionization model using a central power law continuum source with a spectral index of alpha = -1.2 as deduced from the observed flux distribution. A multi-density, dusty gas gives the best fit to the observed emission line spectrum. Our calculations show that the small contribution from a highly ionized gas observed in NGC 1052 can also be reproduced solely by photoionization modeling. The high gas covering factor determined from our model is consistent with the assumption that our line of sight to the central engine is obscured.

description: The gravitational waveform of merging binary neutron stars encodes information about extreme states of matter. Probing these gravitational emissions requires the gravitational-wave detectors to have high sensitivity above 1 kHz. Fortunately for current advanced detectors, there is a sizeable gap between the quantum-limited sensitivity and the classical noise at high frequencies. Here we propose a detector design that closes such a gap by reducing the high-frequency quantum noise with an active optomechanical filter, frequency-dependent squeezing, and high optical power. The resulting noise level from 1 kHz to 4 kHz approaches the current facility limit and is a factor of 20 to 30 below the design of existing advanced detectors. This will allow for precision measurements of (i) the post-merger signal of the binary neutron star, (ii) late-time inspiral, merger, and ringdown of low-mass black hole-neutron star systems, and possible detection of (iii) high-frequency modes during supernovae explosions. This design tries to maximize the science return of current facilities by achieving a sensitive frequency band that is complementary to the longer-baseline third-generation detectors: the10 km Einstein Telescope, and 40 km Cosmic Explorer. We have highlighted the main technical challenges towards realizing the design, which requires dedicated research programs. If demonstrated in current facilities, the techniques can be transferred to new facilities with longer baselines.

description: This paper presents a divergence cleaning formulation for the velocity in the weakly compressible smoothed particle hydrodynamics (SPH) scheme. The proposed hyperbolic/parabolic divergence cleaning, ensures that the velocity divergence, $div(\mathbf{u})$, is minimised throughout the simulation. The divergence equation is coupled with the momentum conservation equation through a scalar field $ψ$. A parabolic term is added to the time-evolving divergence equation, resulting in a hyperbolic/parabolic form, dissipating acoustic waves with a speed of sound proportional to the local Mach number in order to maximise dissipation of the velocity divergence, preventing unwanted diffusion of the pressure field. The $div(\mathbf{u})$-SPH algorithm is implemented in the open-source weakly compressible SPH solver DualSPHysics. The new formulation is validated against a range of challenging 2-D test cases including the Taylor-Green vortices, patch impact test, jet impinging on a surface, and wave impact in a sloshing tank. The results show that the new formulation reduces the divergence in the velocity field by at least one order of magnitude which prevents spurious numerical noise and the formation of unphysical voids. The temporal evolution of the impact pressures shows that the $div(\mathbf{u})$-SPH formulation virtually eliminates unwanted acoustic pressure oscillations. Investigation of particle resolution confirms that the new $div(\mathbf{u})$-SPH formulation does not reduce the spatial convergence rate.

description: The purpose of this study is to investigate mitigation potential of tree-crop cultivations in the Mediterranean region and particularly in Spain, Italy and Greece. In that respect, a methodology is developed, built on top of different parameters affecting the sequestration in tree-crops and providing us with the vital compatibility to apply it in the Mediterranean region and set the framework up to generalize it for other regions in the future. The key parameters that were considered, are the tree-crop type, environmental conditions, the climatological conditions and the socioeconomic dimension of the cultivation. In that direction, field measurements for five representative tree-crops were made, and the relative management practices applied by the farmers were gathered with questionnaires. The current climatic conditions were collected as well as the future conditions were evaluated by projecting for the next 50 years with the use of a Global Climate Model. Based on these, an estimation algorithm was developed (CO2 Removal Capacity Algorithm) that captures the yearly CO2 balance in Biomass, Soil and the enclosed management practices and can be applied specifically at different regions of the study area. As a result, different cultivation practices are evaluated, and their mitigation potentials accordingly ranked. Our study identifies certain mitigation potentials of the agricultural sector and hence contributes to the development of climatic policies coupling agricultural, economic and climatic objectives.

description: Accurate location of people in indoor environments is a key aspect of many applications such as resource management or security. In this paper, we explore the use of short-range radio technologies to track people indoors. The network consists of two kind of radio nodes: static nodes (anchors) and mobile nodes (people). From a set of sparse connectivity matrices (people vs. people and people vs. anchors) at each time instant and people's dynamics, we infer people's trajectories. To combine connectivity and dynamic information, we propose an extension of Multidimensional Scaling (MDS), Dynamic Weighted MDS (DWMDS), that finds an embedding of people's trajectories (x and y coordinates of people through time). DWMDS has proven to be more ac- curate and effective, especially for low connectivity degree networks (i.e. sparse networks), compared to existing location algorithms. Extensive simulations show the effectiveness and robustness of the proposed algorithm.

description: The $g$ factor of the $4_1^+$ state in $^{68}$Zn has been remeasured with improved energy resolution of the detectors used. The value obtained is consistent with the previous result of a negative $g$ factor thus confirming the dominant $0g_{9/2}$ neutron nature of the $4_1^+$ state. In addition, the accuracy of the $g$ factors of the $2_1^+$, $2_2^+$ and $3_1^-$ states has been improved an d their lifetimes were well reproduced. New large-scale shell model calculations based on a $^{56}$Ni core and an $0f_{5/2}1pg_{9/2}$ model space yield a theoretical value, $g(4_1^+) = +0.008$. Although the calculated value is small, it cannot fully explain the experimental value, $g(4_1^+) = -0.37(17)$. The magnitude of the deduced B(E2) of the $4_1^+$ and $2_1^+$ transition is, however, rather well described. These results demonstrate again the importance of $g$ factor measurements for nuclear structure determination s due to their specific sensitivity to detailed proton and neutron components in the nuclear wave functions.

The inviscid limit of Navier-Stokes for analytic data on the half-space

description: In their classical work Caflisch and Sammartino proved the inviscid limit of the incompressible Navier-Stokes equations for well-prepared data with analytic regularity in the half-space. Their proof is based on the detailed construction of Prandtl's boundary layer asymptotic expansions. In this paper, we give a direct proof of the inviscid limit for general analytic data without having to construct Prandtl's boundary layer correctors. Our analysis makes use of the boundary vorticity formulation and the abstract Cauchy-Kovalevskaya theorem on analytic boundary layer function spaces that capture unbounded vorticity.

description: Excerpts from the report: Since World War II there has been a large expansion in total domestic waterborne traffic. The purpose of this study of changes in the waterborne movement of agricultural commodities and farm supplies between 1949 and 1957 is to (1) supplement previous studies on rail and truck movement of agricultural commodities , (2) form a basis for future research on water transportation of these products, and (3) identify significant aspects of domestic water transportation that may merit more intensive investigation because of their impact on other modes of agricultural transportation. The basic data in the report were drawn from Domestic Waterborne Commerce of the United States, published by the U. S. Corps of Engineers, Department of the Army.
X-Ray Variability Coherence: How to Compute it, What it Means, and How it Constrains Models of Cyg X-1 and GX 339-4

description: We describe how the coherence function, a Fourier frequency-dependent measure of the linear correlation between time series measured simultaneously in two energy channels, can be used in conjunction with energy spectra, power spectra, and time delays between energy channels to constrain models of the spectrum and variability of x-ray binaries. Here we present a procedure for estimating the coherence function in the presence of counting noise. We apply this method to the black hole candidates Cyg X--1 and GX 339--4, and find that the near perfect coherence between low and high energy x-ray photons rules out a wide range of models that postulate: spatially extended fluctuating emission, thermal flares, and overlapping shot-noise.
