description: The carbon, oxygen and clumped isotope compositions of carbonates are typically analyzed by carbonate-phosphoric acid digestion. Although this approach has been widely used since the 1950s, this procedure has problems in the operability. To address these issues, an improved apparatus with properly sized accessories, including an I-shaped vessel, a sample boat, a magnet, and a magnetic stir bar, has been developed for sample digestion. Similar to a long neck flask, this apparatus has a straight and axisymmetric structure, providing advantages in terms of cost and operability, and thus can be easily implemented in both open and sealed vessel digestion. To evaluate the reliability of the stable and clumped isotope compositions using this new vessel, international and interlaboratory carbonate standards were analyzed with this new apparatus and two commonly used Y-shaped and T-shaped vessels. The results using the new apparatus were consistent with those obtained by the others and in previous studies, suggesting suitability for the traditioinal phosphoric acid digestion of carbonates.

Thermal measurements of stationary nonequilibrium systems: A test for generalized thermostatistics

description: We show that a gas thermometer in contact with a stationary classical system out of thermal (Boltzmann) equilibrium evolves, under very general conditions, towards a state characterized by a Levy velocity distribution. Our approach is based on a kinetic-like equation that applies to a wide class of models for the system-thermometer interaction. The results clarify the role of non-exponential energy distributions as possible generalizations of the Boltzmann distribution for systems where the usual formulation of thermostatistics may not apply. In particular, they show that the power-law distributions derived from Tsallis's nonextensive formalism are irrelevant to the stationary state of the thermometer, thus failing to give a consistent description of the system-thermometer equilibrium. We point out the need of a generalized thermostatistical formulation able to give a unified frame to Levy and Maxwell distributions.

description: We have evidenced by small angle neutron scattering at low temperature the coexistence of ferromagnetism (F) and antiferromagnetism (AF) in Pr0.67Ca0.33MnO3. The results are compared to those obtained in Pr0.80Ca0.20MnO3 and Pr0.63Ca0.37MnO3, which are F and AF respectively. Quantitative analysis shows that the small angle scattering is not due to a mesoscopic mixing but to a nanoscopic electronic and magnetic ''red cabbage'' structure, in which the ferromagnetic phase exists in form of thin layers in the AF matrix (stripes or 2D ''sheets'').

description: Since the previous TDR version 0.1, the hardware development has made significant progress. The universal quench detection system, CLIQ and energy extraction system prototypes have been successfully produced and tested and first units have been successfully deployed and used in SM18. This progress is reflected in the Sections below and some of the previously retained options have therefore been removed. In addition, the development of the quench heater power supplies for the HL-LHC is well advanced, which is shown in the respective Section below. Chapter 6 was updated following the approval of layout changes to the triplet circuit and an additional Section on cold diodes was added, as they have been adopted within the HL-LHC baseline. Finally, two new sources for very fast failures have been identified and studied in the past years, which is presented in the Section on fast failures.

Quantum Nonlinear Acoustic Hall Effect and Inverse Acoustic Faraday Effect in Dirac Insulators

description: We propose to realize the quantum nonlinear Hall effect and the inverse Faraday effect through the acoustic wave in a time-reversal invariant but inversion broken Dirac insulator. We focus on the acoustic frequency much lower than the Dirac gap such that the interband transition is suppressed and these effects arise solely from the intrinsic valley-contrasting band topology. The corresponding acoustoelectric conductivity and magnetoacoustic susceptibility are both proportional to the quantized valley Chern number and independent of the quasiparticle lifetime. The linear and nonlinear components of the longitudinal and transverse topological currents can be tuned by adjusting the polarization and propagation directions of the surface acoustic wave. The static magnetization generated by a circularly polarized acoustic wave scales linearly with the acoustic frequency as well as the strain-induced charge density. Our results unveil a quantized nonlinear topological acoustoelectric response of gapped Dirac materials, like hBN and transition-metal dichalcogenide, paving the way toward room-temperature acoustoelectric devices due to their large band gaps.

description: In this paper, we consider channel estimation for intelligent reflecting surface (IRS)-assisted millimeter wave (mmWave) systems, where an IRS is deployed to assist the data transmission from the base station (BS) to a user. It is shown that for the purpose of joint active and passive beamforming, the knowledge of a large-size cascade channel matrix needs to be acquired. To reduce the training overhead, the inherent sparsity in mmWave channels is exploited. By utilizing properties of Katri-Rao and Kronecker products, we find a sparse representation of the cascade channel and convert cascade channel estimation into a sparse signal recovery problem. Simulation results show that our proposed method can provide an accurate channel estimate and achieve a substantial training overhead reduction.

description: This study aimed to evaluate the longitudinal association between sweet potato intake and risk of NAFLD in the general adult population. In total, the number of 15,787 participants (males, 42.4%) was included in this prospective cohort study. Sweet potato intake was assessed by using a validated food frequency questionnaire. NAFLD was diagnosed by transabdominal sonography during an annual health examination. Cox proportional hazards regression models were fitted to assess the hazard ratios (HRs) and 95% confidence intervals (CIs) across categories of energy-adjusted sweet potato intake. Compared to participants with the lowest tertile of sweet potato intake, the finally adjusted HRs (95% CIs) of incident NAFLD for those with the highest tertile were 0.87 (0.78, 0.97) in males (p for trend = 0.009); and 1.05 (0.92, 1.21) in females (p for trend = 0.52). Our study revealed that sweet potato intake was inversely associated with the risk of NAFLD in males.

description: We study the structure and performance of the coffee export sector in Ethiopia, Africa’s most important coffee producer, over the period 2003 to 2013. We find an evolving policy environment leading to structural changes in the export sector, including an elimination of vertical integration for most exporters. Ethiopia’s coffee export earnings improved dramatically over this period, i.e. a four-fold real increase. This has mostly been due to increases in international market prices. Quality improved only slightly over time, but the quantity exported increased by 50 percent, seemingly explained by increased domestic supplies as well as reduced local consumption. To further improve export performance, investments to increase the quantities produced and to improve quality are needed, including an increase in washing, certification, and traceability, as these characteristics are shown to be associated with significant quality premiums in international markets.

LSB Galaxies and the Tully-Fisher Relation

description: We present VLA HI imaging of four LSB galaxies which were thought to strongly deviate from the TF relation based on Arecibo single-dish observations. We do not detect three of the four targeted LSB galaxies in HI down to a 4-sigma limit of 0.08Jy km/s. We find that two of the four of these LSBs have bright galaxies which have contaminated the Arecibo signal. A further examination of the Arecibo sample shows that five out of the six galaxies that were found to deviate from TF have nearby bright galaxies and we conclude that possibly all but one of the non-TF galaxies are contaminated by HI from nearby galaxies. The sixth galaxy was not detected by us. A new observation by Arecibo did not confirm the earlier detection. The integrated profiles of the bright galaxies are consistent with the Arecibo results both in velocity range and amplitude, which indicates that most of the extreme deviators from the TF relation must have been affected by bright companions in this earlier HI survey. A more recent determination of the sidelobe structure of the Arecibo beam supports our conclusion and shows that the degree of sidelobe contamination was much larger than could have been initially predicted. Hence, we have corrected the results found in O'Neil et al. (2000) and have reconstructed the TF relation. These new observations then show a) a reconstructed TF relation that has relatively large scatter at all values of rotational velocity (possibly indicating the true range in disk galaxy properties) and b) the presence of at least some red, gas poor, LSB disks that indeed may be in an advanced evolutionary state as the faded remnants of their former high surface brightness actively star forming state.

description: The warm powering of the HL-LHC involves the new circuits of the Inner Triplets and the Separation/Recombination magnets in Point 1 and Point 5, the powering of the 11 T magnets in Point 7, and the final R2E consolidation phase in LS3. The LHC was built with modular power converters to facilitate maintenance and integrate the redundancy principle. Redundancy was foreseen in power converters rated above 600 A. This has proven to be a real asset during operation. The n + 1 redundancy indeed allows the converter to be operated even with one module in fault. The advantages are: (i) in case of fault, only one sub- converter is not operational and usually this does not generate a beam dump; (ii) the LHC can run with some faulty sub-converters and all interventions for repairing can be performed during a technical stop of the machine. With the exception of dipole circuits (whose power converters are based on thyristors technology), switch-mode technology was chosen for the LHC power converters in order to minimize their size and assure low output voltage ripple. All LHC power converters rated at currents above 120 A are water-cooled, inducing a size reduction of the hardware. All these design principles will be maintained for the new HL-LHC power converters and the use of switch-mode technology extended to all new designs.

The magnets will be installed in the machine during LS3. In addition to these changes, during LS2, two main dipole magnets (MB) will be replaced by 11T cryo-assemblies (MBH) in order to allow the addition of two extra collimators at warm to intercept dispersive beam losses originating from the collimation system installed in point 7. The two concerned dipole magnets that are to be replaced are MBB.A9L7 and MBA.A9R7.

description: The effects of a (non co-crystallizing) nucleating agent on secondary nucleation rate and final lamellar thickness in isothermally melt-crystallizing polyethylene oxide are considered. SAXS reveals that lamellae formed in nucleated samples are thinner than in the pure samples crystallized at the same undercoolings. These results are in quantitative agreement with growth rate data obtained by calorimetry, and are interpreted as the effect of a local decrease of the basal surface tension, determined mainly by the nucleant molecules diffused out of the regions being about to crystallize. Quantitative agreement with a simple lattice model allows for some interpretation of the mechanism.

Strong hyperfine interaction between the electron spin and the spins of the first three shells of $^{13}$C atoms allows to operate the state of the register on the submicrosecond timescale using microwave pulses only. We describe the system and the operating regime analytically and numerically, as well as simulate the initialization protocols.

The Meaning of Infrared Singularities in Noncommutative Gauge Theories
Creators: name: Van Raamsdonk, Mark
Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We point out that the leading infrared singular terms in the effective actions of noncommutative gauge theories arising from nonplanar loop diagrams have a natural interpretation in terms of the matrix model (operator) formulation of these theories. In this formulation (for maximal spatial noncommutativity), noncommutative space arises as a configuration of an infinite number of D-particles. We show that the IR singular terms correspond to instantaneous linear potentials between these D-particles resulting from the zero point energies of fluctuations about this background. For theories with fewer fermionic than bosonic degrees of freedom, such as pure noncommutative gauge theory, the potential is attractive and renders the theory unstable. With more fermionic than bosonic degrees of freedom, the potential is repulsive and we argue that the theory is stable, though oddly behaved.

description: Levitated nanoparticles and microparticles are excellent candidates for the realization of extremely isolated mechanical systems, with a huge potential impact in sensing applications and in quantum physics. Magnetic levitation based on static fields is a particularly interesting approach, due to the unique property of being completely passive and compatible with low temperatures. Here, we show experimentally that micromagnets levitated above type-I superconductors feature very low damping at low frequency and low temperature. In our experiment, we detect 5 out of 6 rigid-body mechanical modes of a levitated ferromagnetic microsphere, using a dc SQUID (Superconducting Quantum Interference Device) with a single pick-up coil. The measured frequencies are in agreement with a finite element simulation based on ideal Meissner effect. For two specific modes we find further substantial agreement with analytical predictions based on the image method. We measure damping times $τ$ exceeding $10^4$ s and quality factors $Q$ beyond $10^7$, improving by $2-3$ orders of magnitude over previous experiments based on the same principle. We investigate the possible residual loss mechanisms besides gas collisions, and argue that much longer damping time can be achieved with further effort and optimization. Our results open the way towards the development of ultrasensitive magnetomechanical sensors with potential applications to magnetometry and gravimetry, as well as to fundamental and quantum physics.

description: Imp-I∼III were observed for the first time after a 4-hour thermal degradation study of brivaracetam at 130 °C. These three degradants were prepared and purified through targeted and regiospecific synthesis, and were further characterized by 1D-NMR and 2D-NMR. After differentiation from other isomers, Imp-I was identified as (2S)-2-((3R)-2,5-dioxo-3-propylpyrrolidin-1-yl)butanamide; Imp-II was identified as (2S)-2-((3R,4S)-3-hydroxy-2-oxo-4-propylpyrrolidin-1-yl)butanamide; and Imp-III was identified as (S)-2-(2-oxo-4-propyl-2,5-dihydro-1H-pyrrol-1-yl)butanamide. Besides, in-silico toxicity prediction confirmed a high probability of non-mutagenicity of the three impurities. By preparing and characterizing the degradants, product stability of Brivaracetam under even extreme conditions was better understood, thus further ensuring product quality.

description: In extended supersymmetric models with a hidden sector the lightest $R$-parity odd particle can reside in the hidden sector and act as dark matter. We consider the case when the hidden sector has ultraweak interactions with the visible sector. An interesting phenomenon arises if the LSP of the visible sector is charged in which case it will decay to the hidden sector dark matter. Due to the ultraweak interactions, the LSP of the visible sector will be long-lived decaying outside the detector after leaving a track inside. We investigate this possibility in the framework of a $U(1)_X$-extended MSSM/SUGRA model with a small gauge kinetic mixing and mass mixing between the $U(1)_X$ and $U(1)_Y$ where $U(1)_Y$ is the gauge group of the hypercharge. Specifically we investigate the case when the LSP of MSSM is a stop which decays into the hidden sector dark matter and has a lifetime long enough to traverse the LHC detector without decay. It is shown that such a particle can be detected at the HL-LHC and HE-LHC as an $R$-hadron which will look like a slow moving muon with a large transverse momentum $p_T$ and so can be detected by the track it leaves in the inner tracker and in the muon spectrometer. Further, due to the ultraweak couplings between the hidden sector and the MSSM fields, the dark matter particle has a relic density arising from a combination of the freeze-out and freeze-in mechanisms. It is found that even for the ultraweak or feeble interactions the freeze-out contribution relative to freeze-in contribution to the relic density is substantial to dominant, varying between 30\% to 74\% for the model points considered. It is subdominant to freeze-in for relatively small stop masses with relatively larger stop annihilation cross-sections and the dominant contribution to the relic density for relatively large stop masses and relatively smaller stop annihilation cross-sections.

description: Agriculture and forestry have been the mainstay of Virginia economy, contributing about $80 billion annually to the economy. The changing demography of consumers and advances in technology have facilitated a paradigm shift in food and retail sales. This study focuses on understanding and explaining these consumer trends and the underlying causes of the transformation in the food and retail sectors across 134 counties and cities in Virginia. In the wake of current concerns about access to nutritious food, this study also examines the effects of food and retail stores concentration on incidences of food desert in the State. A two-step approach was used in the data analysis. First, retail concentration in Virginia was analyzed by determine retail pull factors, market share, trade area capture, buying power and commuting patterns of customers and growth in the food and retail sector over the last two decades. Second, a spatial regression model was used to examine the strength of food and retail sectors. The retail trends and their impacts on identified food deserts and economic activity will be useful to analysts and decision makers in public policy in developing effective programs for enhancing the socioeconomic activities for their constituents

description: Relaxation of a two-level system (TLS) into a resonant infinite-temperature reservoir with a Lorentzian spectrum is studied. The reservoir is described by a complex Gaussian-Markovian field coupled to the nondiagonal elements of the TLS Hamiltonian. The theory can be relevant for electromagnetic interactions in microwave high-$Q$ cavities and muon spin depolarization. Analytical results are obtained for the strong-coupling regime, $Ω_0\ggν$, where $Ω_0$ is the rms coupling amplitude (Rabi frequency) and $ν$ is the width of the reservoir spectrum. In this regime, the population difference and half of the initial coherence decay with two characteristic rates: the most part of the decay occurs at $t\simΩ_0^{-1}$, the relaxation being reversible for $t\ll(Ω_0^2ν)^{-1/3}$, whereas for $t\gg(Ω_0^2ν)^{-1/3}$ the relaxation becomes irreversible and is practically over. The other half of the coherence decays with the rate on the order of $ν$, which may be slower by orders of magnitude than the time scale of the population relaxation. The above features are explained by the fact that at $t\llν^{-1}$ the reservoir temporal fluctuations are effectively one-dimensional (adiabatic). Moreover, we identify the pointer basis, in which the reduction of the state vector occurs. The pointer states are correlated with the reservoir, being dependent on the reservoir phase.

description: The aim of this research is to find and show the effectiveness of Strychnos potatorum seeds as a natural coagulant for purifying and producing potable water in flood prone rural areas of Bangladesh. Strychnos potatorum, locally called 'Nirmali' or 'Nirmala', is a natural coagulant which was used in the Indian Subcontinent during the stone ages but has slowly become forgotten. This research was carried out to reintroduce this ancient coagulant and find its effectiveness during floods, particularly in Bangladesh. As a riverine country prone to flooding and devoid of quality water purification systems, coagulants like alum and ferric sulfates are often used although these synthetic chemicals have been found producing DBPs in water which are associated with certain health hazards. And so, replacing these synthetic chemicals with a natural coagulant such as Strychnos potatorum seeds in flood prone rural areas will be a beneficial and cheap water purification system for the populace. To prove the effectiveness, various tests were carried out across flood prone areas around Dhaleshwari River (Nagarpur, Tangail) to find out whether Strychnos potatorum seeds will be able to replace the commonly used chemical coagulants and provide drinkable water to the flood affected people or not. The reason behind selecting this region for research purpose is that the soil and tree characteristics of this area is perfect for planting and growing Strychnos potatorum trees and they can be easily distributed among the populace when disaster hits. Our test results have shown that the Strychnos potatorum seeds are highly effective when it is used to treat water in these flood prone areas. And our initial estimation is Strychnos potatorum will provide a remarkably successful and high yield in these targeted areas. According to our calculations and research it will cost only 0.00018 dollars or for per liter of water treatment. As the project will require planting Strychnos potatorum trees, the project will improve the environment and distributing them to flood affected populace will increase the peoples' awareness regarding tree plantation and drinking safe water. Also, this project will act as a replacement to the synthetic chemical coagulants used in the flood affected rural areas of Bangladesh and replacing those synthetic chemical coagulants with biodegradable Strychnos potatorum will be good for the environment as a whole as there will be less chemical waste.

description: The world population is expected to grow to 7.7 billion in 2020, from 5.3 billion in 1993 (UN, 1996). Although the latest population projections represent a slowdown from past estimates, the large absolute increase in population raises serious concerns about how food demand will be met in the next decades, especially in the context of a possibly stagnant or even decreasing stock of natural resources. These concerns have escalated sharply in recent years, in the face of dramatic increases in world cereal prices in 1996, combined with declining cereal stocks, and the simultaneous appearance of several widely read publications presenting the possibility of a starving world in the next century, unable to meet growing food demands from a deteriorating natural resource base (Brown, 1995; Tyler, 1995; Brown and Kane, 1994). In this paper, we examine the prospects for global food supply and demand for the year 2020, in the light of the two most often identified natural resource constraints, land and water. We first briefly summarize recent trends in area, yield and production for cereal crops, the key staple crops for most of the world, describe the IMPACT global food projections model and present an overview of food demand and supply projections. We then ask whether land and water constraints will pose serious threats to long-term cereal production growth. In particular, we assess the effects of land degradation and land conversion to urban uses on agricultural production and the effect of increasing water scarcity on future global food supply. For the latter assessment, we develop projections of global water demand until 2020 that are consistent with the underlying assumptions in the global food projections. We conclude with implications for land and water policy.

description: The electromagnetic properties and microwave absorption capabilities are studied in an anechoic chamber under real radar conditions for mono and bilayer composite samples consisting of a polymeric matrix and a magnetic powder filler, either metallic or ceramic. The effect of the filler type and the filling factor is investigated. The results demonstrate exceptional broadband microwave absorption, making these materials highly suitable for stealth technology applications. The experimentally measured absorptions reach -40 dB, while model-based predictions suggest that these systems could overpass the barrier of -50 dB. The experimental results are supported by models, both for single and bilayer systems.

description: Let $s_0,s_1,\dots,s_{m-1}$ be complex numbers and $r_0,\dots,r_{m-1}$ rational integers in the range $0\le r_j\le m-1$. Our first goal is to prove that if an entire function $f$ of sufficiently small exponential type satisfies $f^{(mn+r_j)}(s_j)\in{\mathbb Z}$ for $0\le j\le m-1$ and all sufficiently large $n$, then $f$ is a polynomial. Under suitable assumptions on $s_0,s_1,\dots,s_{m-1}$ and $r_0,\dots,r_{m-1}$, we introduce interpolation polynomials $Λ_{nj}$, ($n\ge 0$, $0\le j\le m-1$) satisfying $$ Λ_{nj}^{(mk+r_\ell)}(s_\ell)=δ_{j\ell}δ_{nk}, \quad\hbox{for}\quad n, k\ge 0 \quad\hbox{and}\quad 0\le j, \ell\le m-1 $$ and we show that any entire function $f$ of sufficiently small exponential type has a convergent expansion $$ f(z)=\sum_{n\ge 0} \sum_{j=0}^{m-1}f^{(mn+r_j)}(s_j)Λ_{nj}(z). $$ The case $r_j=j$ for $0\le j\le m-1$ involves successive derivatives $f^{(n)}(w_n)$ of $f$ evaluated at points of a periodic sequence ${\mathbf{w}}=(w_n)_{n\ge 0}$ of complex numbers, where $w_{mh+j}=s_j$ ($h\ge 0$, $0\le j\le m$). More generally, given a bounded (not necessarily periodic) sequence ${\mathbf{w}}=(w_n)_{n\ge 0}$ of complex numbers, we consider similar interpolation formulae $$ f(z)=\sum_{n\ge 0}f^{(n)}(w_n)Ω_{\mathbf{w},n}(z) $$ involving polynomials $Ω_{\mathbf{w},n}(z)$ which were introduced by W.~Gontcharoff in 1930. Under suitable assumptions, we show that the hypothesis $f^{(n)}(w_n)\in{\mathbb Z}$ for all sufficiently large $n$ implies that $f$ is a polynomial.

description: We present a theoretical study of linear wave scattering in one-dimensional nonlinear lattices by intrinsic spatially localized dynamic excitations or discrete breathers. These states appear in various nonlinear systems and present a time-periodic localized scattering potential for plane waves. We consider the case of elastic one-channel scattering, when the frequencies of incoming and transmitted waves coincide, but the breather provides with additional spatially localized ac channels whose presence may lead to various interference patterns. The dependence of the transmission coefficient on the wave number q and the breather frequency Omega_b is studied for different types of breathers: acoustic and optical breathers, and rotobreathers. We identify several typical scattering setups where the internal time dependence of the breather is of crucial importance for the observed transmission properties.

description: Gaudi, Naber & Sackett pointed out that if an event is caused by a lens system containing more than two planets, all planets will affect the central region of the magnification pattern, and thus the existence of the multiple planets can be inferred by detecting additionally deformed anomalies from intensive monitoring of high magnification events. Unfortunately, this method has important limitations in identifying the existence of multiple planets and determining their parameters due to the degeneracy of the resulting light curve anomalies from those induced by a single planet and the complexity of multiple planet lensing models. In this paper, we propose a new channel to search for multiple planets via microlensing. The method is based on the fact that the anomalies induced by multiple planets are well approximated by the superposition of those of the single planet systems where the individual planet-primary pairs act as independent lens systems. Then, if the source trajectory passes both of the outer deviation regions induced by the individual planets, one can unambiguously identify the existence of the multiple planets. We illustrate that the probability of successively detecting light curve anomalies induced by two Jovian-mass planets located in the lensing zone through this channel will be substantial. Since the individual anomalies can be well modeled by much simpler single planet lensing models, the proposed method has an important advantage of allowing one to accurately determine the parameters of the individual planets.
