description: The generic transition in the boson Hubbard model, occurring at an incommensurate chemical potential, is studied in the link-current representation using the recently developed directed geometrical worm algorithm. We find clear evidence for a multi-peak structure in the energy distribution for finite lattices, usually indicative of a first order phase transition. However, this multi-peak structure is shown to disappear in the thermodynamic limit revealing that the true phase transition is second order. These findings cast doubts over the conclusion drawn in a number of previous works considering the relevance of disorder at this transition.

r-modes in Relativistic Superfluid Stars

description: We discuss the modal properties of the $r$-modes of relativistic superfluid neutron stars, taking account of the entrainment effects between superfluids. In this paper, the neutron stars are assumed to be filled with neutron and proton superfluids and the strength of the entrainment effects between the superfluids are represented by a single parameter $η$. We find that the basic properties of the $r$-modes in a relativistic superfluid star are very similar to those found for a Newtonian superfluid star. The $r$-modes of a relativistic superfluid star are split into two families, ordinary fluid-like $r$-modes ($r^o$-mode) and superfluid-like $r$-modes ($r^s$-mode). The two superfluids counter-move for the $r^s$-modes, while they co-move for the $r^o$-modes. For the $r^o$-modes, the quantity $κ\equivσ/Ω+m$ is almost independent of the entrainment parameter $η$, where $m$ and $σ$ are the azimuthal wave number and the oscillation frequency observed by an inertial observer at spatial infinity, respectively. For the $r^s$-modes, on the other hand, $κ$ almost linearly increases with increasing $η$. It is also found that the radiation driven instability due to the $r^s$-modes is much weaker than that of the $r^o$-modes because the matter current associated with the axial parity perturbations almost completely vanishes.

Source Depth of Three-minute Umbral Oscillations

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We infer the depth of the internal sources giving rise to three-minute umbral oscillations. Recent observations of ripple-like velocity patterns of umbral oscillations supported the notion that there exist internal sources exciting the umbral oscillations. We adopt the hypothesis that the fast magnetohydrodynamic (MHD) waves generated at a source below the photospheric layer propagate along different paths, reach the surface at different times, and excited slow MHD waves by mode conversion. These slow MHD waves are observed as the ripples that apparently propagate horizontally. The propagation distance of the ripple given as a function of time is strongly related to the depth of the source. Using the spectral data of the Fe I 5435A line taken by the Fast Imaging Solar Spectrograph of the Goode Solar Telescope at Big Bear Solar Observatory, we identified five ripples and determined the propagation distance as a function of time in each ripple. From the model fitting to these data, we obtained the depth between 1000 km and 2000 km. Our result will serve as an observational constraint to understanding the detailed processes of magnetoconvection and wave generation in sunspots.

description: We report the details and revised analysis of an experiment to measure the specific heat of helium with subnanokelvin temperature resolution near the lambda point. The measurements were made at the vapor pressure spanning the region from 22 mK below the superfluid transition to 4 uK above. The experiment was performed in earth orbit to reduce the rounding of the transition caused by gravitationally induced pressure gradients on earth. Specific heat measurements were made deep in the asymptotic region to within 2 nK of the transition. No evidence of rounding was found to this resolution. The optimum value of the critical exponent describing the specific heat singularity was found to be a = -0.0127+ - 0.0003. This is bracketed by two recent estimates based on renormalization group techniques, but is slightly outside the range of the error of the most recent result. The ratio of the coefficients of the leading order singularity on the two sides of the transition is A+/A- =1.053+ - 0.002, which agrees well with a recent estimate. By combining the specific heat and superfluid density exponents a test of the Josephson scaling relation can be made. Excellent agreement is found based on high precision measurements of the superfluid density made elsewhere. These results represent the most precise tests of theoretical predictions for critical phenomena to date.

description: We examine fertilizer use among sorghum growers within Malian households in the Sudan Savanna. Dryland cereals in this region are typically produced by extended family members who are vertically (i.e., unmarried sons, married sons and their families) or horizontally (i.e., brothers; multiple wives) related to the head of the family farm enterprise. The head is usually an elder patriarch, or a work leader he designates. The head guides the organization of production on large plots labored collectively with the goal of meeting the staple food needs of the extended family. Custodian of the family’s land use rights, he also allocates individual plots to household members who cultivate them privately to meet personal needs. We test intrahousehold differences in fertilizer adoption, efficiency and productivity by plot manager’s gender and relationship to head. We apply a well-known econometric approach applied previously by researchers to data collected in Mali and Burkina Faso. In comparison with earlier research, we are able to control for unobserved variation in soil characteristics. We find that fertilizer application per ha on sorghum is on average higher among women than men. When we control for unobserved soil quality, we find little evidence that intrahousehold fertilizer allocation is inefficient, although productivity differentials persist. Further, differences in marginal products of nitrogen between female- and male-managed sorghum plots are not statistically significant. Findings have implications for design of programs to support cereals intensification in Mali.

description: The Rural Economy and Agriculture Dry Zone Survey (READZ) community survey was conducted in mid-2017 in 300 villages in 14 townships across Mandalay, Sagaing, and Magway. These regions are located in Myanmar’s Central Dry Zone - one of the country’s most important agricultural zones. The survey was designed to facilitate analysis of recent changes in the rural economy of the Dry Zone. Data was collected through group interviews conducted with knowledgeable long term residents in each of the communities surveyed. The survey collected data on recent changes in physical and social infrastructure, transport and mobility, irrigation access, cropping patterns, agricultural mechanization and labor costs, numbers of off-farm enterprises, and access to credit. Key findings are summarized below.

description: We present the results of charged particle fluctuations measurements in Au + Au collisions at $\sqrt{s_{NN}}=130$ GeV using the STAR detector. Dynamical fluctuations measurements are presented for inclusive charged particle multiplicities as well as for identified charged pions, kaons, and protons. The net charge dynamical fluctuations are found to be large and negative providing clear evidence that positive and negative charged particle production is correlated within the pseudorapidity range investigated. Correlations are smaller than expected based on model-dependent predictions for a resonance gas or a quark gluon gas which undergoes fast hadronization and freeze-out. Qualitative agreement is found with comparable scaled p+p measurements and a HIJING model calculation based on independent particle collisions, although a small deviation from the 1/N scaling dependence expected from this model is observed.

description: Given their simplicity and presumed commodity-like nature, institutional S&P 500 Index mutual funds should be subject to active price competition, resulting in only nominal size-adjusted differences in expenses. We find a wide disparity among fund expense ratios and their corresponding characteristics and performance. Overall, the evidence suggests some price competition among institutional S&P 500 Index funds, but not to the extent that they may be considered financial commodities. One explanation for the existence of high-priced index funds is that they tend to require significantly lower minimum initial purchases. Our data do not support the notion that institutional investors buy high-priced S&P 500 index funds to access broader or lower-cost investment services from fund families. We conclude the market for institutional S&P 500 Index funds is not completely homogenous.

description: With this study, we have three main objectives. First, we aim to provide evidence about the multi-unit amplification hypothesis by randomly allocating participants to one multi-unit context (different-unit multi-source evaluations), and two single-unit contexts (same-unit multi-source evaluations and single-source evaluations). Second, we aim to identify the locus of the multi-unit amplification. We predict the presence of relative weights effects. Third, we aim to provide evidence for the mechanism based on the amplification of the perceived difference in informativeness between estimates reported in different units. We predict that the difference in perceived informativeness of estimates reported in a more fine-grained unit and those reported in a less fine-grained unit will be stronger in multi-unit contexts than in comparisons of single-unit contexts.

description: The first measurements of dielectron production at midrapidity ($|η_{c}|<0.8$) in proton-proton and proton-lead collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV at the LHC are presented. The dielectron cross section is measured with the ALICE detector as a function of the invariant mass $m_{\rm{ee}}$ and the pair transverse momentum $p_{\rm{T,ee}}$ in the ranges $m_{\rm{ee}}$ < 3.5 GeV/$c^{2}$ and $p_{\rm{T,ee}}$ < 8.0 GeV/$c^{2}$, in both collision systems. In proton-proton collisions, the charm and beauty cross sections are determined at midrapidity from a fit to the data with two different event generators. This complements the existing dielectron measurements performed at $\sqrt{s}$ = 7 and 13 TeV. The slope of the $\sqrt{s}$ dependence of the three measurements is described by FONLL calculations. The dielectron cross section measured in proton-lead collisions is in agreement, within the current precision, with the expected dielectron production without any nuclear matter effects for $\rm{e}^{+}\rm{e}^{-}$ pairs from open heavy-flavor hadron decays. For the first time at LHC energies, the dielectron production in proton-lead and proton-proton collisions are directly compared at the same $\sqrt{s_{\rm{NN}}}$ via the dielectron nuclear modification factor $R_{\rm{pPb}}$. The measurements are compared to model calculations including cold nuclear matter effects, or additional sources of dielectrons from thermal radiation.

description: We report on exploratory Chandra observations of five galactic nuclei that were found to be X-ray bright during the ROSAT all-sky survey (with L_X > 10^43 erg s^-1) but subsequently exhibited a dramatic decline in X-ray luminosity. Very little is known about the post-outburst X-ray properties of these enigmatic sources. In all five cases Chandra detects an X-ray source positionally coincident with the nucleus of the host galaxy. The spectrum of the brightest source (IC 3599) appears consistent with a steep power-law (Gamma~3.6). The other sources have too few counts to extract individual, well-determined spectra, but their X-ray spectra appear flatter (Gamma~2) on average. The Chandra fluxes are ~10^2-10^3 fainter than was observed during the outburst (up to 12 years previously). That all post-outburst X-ray observations showed similarly low X-ray luminosities is consistent with these sources having `switched' to a persistent low-luminosity state. Unfortunately the relative dearth of long-term monitoring and other data mean that the physical mechanism responsible for this spectacular behaviour is still highly unconstrained.

description: The Malian agri-food system is transforming rapidly, in part due to increased demand for processed foods that are easy-to-prepare and ready-to-eat by the growing urban consumers. Yet, little is known about the scale and scope of this ongoing transformation in the agri-food system. To better understand the general trends in terms of diversity, availability and prevalence of imports as well as key characteristics of processed foods, we conducted a city-retail outlet inventory of processed dairy and cereal foods in 2016. We visited 100 retail outlets, including central and neighborhood markets, supermarkets as well as neighborhood and grocery stores, located across low, medium, and high income neighborhoods of four major cities in Mali. Findings show that: 1) there are 15 and 36 different types of processed dairy and cereal products; 2) availability of processed foods differs widely across neighborhoods, cities, and retail outlets; 3) there is a relatively high dependence on imports; and 4) there exist differences in product attributes across local and imported food products. Taken together, our results indicate that the transformation of the agri-food system is still at its early stages in Mali. The greatest opportunity for the expansion of the Malian agro-processing segment lies in making and selling more processed food items out of locally available raw agricultural materials, since it is where local firms are the most competitive.

Merger motives and target valuation : A survey of evidence from CFOs
Creators: name: Mukherjee, Tarun K.
name: Baker, H

Publisher: name: American University
Year: 2023

description: This study provides insights about the motives for mergers and acquisitions (M&As) as well as divestitures and the practices used to value targets during 1990-2001. The survey evidence shows that the primary motivation for M&As is to achieve operating synergies while the top-ranked reason for divestitures is to increase focus. The results also show that most firms believe diversification is a justifiable motive for acquisitions most notably as a means of reducing losses during economic downturns. Discounted cash flow methods dominate market multiples as the preferred approach for valuing both publicly-held and closely-held companies. Perhaps the most surprising finding is that although firms often define merger cash flows as the equity cash flows from the target, the discount rate used by acquiring firms is their own WACC rather than the targets’ cost of equity. This finding reflects one of the most persistent bad practices in valuing M&As and might lead to overpayment to targets. [G34]

description: In many developing countries, the greatest potential for sustainable growth lies in the agricultural sector. Yet ironically, poverty is most widespread and often evident in its worst forms in this sector. Many small-scale farmers, and the rural communities in which they live, are trapped in a “cycle” of low margins, resulting in low risk-taking ability and low investment, which in turn leads to low productivity, low market orientation and low value addition which, in turn, nets low margins (ITC, 2006a). The nature and extent of the changing structure of agrifood demand offer unprecedented opportunities for diversification and value addition in agriculture, particularly in developing countries.

description: We introduce a new multi-power-law distribution for the Initial Mass Function (IMF) to explore its potential properties. It follows on prior work that introduced mechanisms accounting for mass accretion in star formation, developed within the framework of general evolution equations for the mass distribution of accreting and non-accreting (proto)stars. This paper uses the same fundamental framework to demonstrate that the interplay between a mass-dependent and a time-dependent step-like dropout rate from accretion leads to IMFs that exhibit multiple power laws for an exponential mass growth. While the mass-dependent accretion and its dropout is intrinsic to each star, the time-dependent dropout might be tied to a specific history such as the rapid consumption of nebular material by nearby stars or the sweeping away of some material by shock waves. The time-dependent dropout folded into the mass-dependent process of star formation is shown to have a significant influence on the IMFs.

description: We study global fixed points for actions of Coxeter groups on nonpositively curved singular spaces. In particular, we consider property FA_n, an analogue of Serre's property FA for actions on CAT(0) complexes. Property FA_n has implications for irreducible representations and complex of groups decompositions. In this paper, we give a specific condition on Coxeter presentations that implies FA_n and show that this condition is in fact equivalent to FA_n for n=1 and 2. As part of the proof, we compute the Gersten-Stallings angles between special subgroups of Coxeter groups.

description: The Nigerian poultry value chain is growing fast and transforming. This is linked to Nigerian diets including more eggs and poultry meat as incomes rise and urbanization occurs. Poultry are important for nutrition as well as incomes in Nigeria. But the poultry value chain is complex – varying over parts of the country in how modern or traditional it is. Really very little has been known about that value chain, as its rapid emergence as an important domestic commercial supply chain is recent. Climate change is also a recently emerging problem and little is known about how it will affect Nigeria’s food economy. These two gaps make it especially unknown what is occurring from the combination of climate change and poultry value chain growth and transformation. How will climate change affect feed supply chains? Poultry farming and supply chains? How will poultry farming itself perhaps affect climate change? We explore these questions in a preliminary way in this brief.
Frustrated Rotations in Nematic Monolayers

description: Tabe and Yokoyama found recently that the optical axis in a chiral monolayer of a ferronematic rotates when water evaporates from the bath: the chiral molecules act as propellers. When the axis is blocked at the lateral walls of the trough, the accumulated rotation inside creates huge splays and bends. We discuss the relaxation of these tensions, assuming that a single dust particle nucleates disclination pairs. For the simplest geometry, we then predict a long delay time followed by a non-periodic sequence of ``bursts''. These ideas are checked by numerical simulations.

description: In 2016, the government of Rwanda (GOR) implemented a zoning policy in the coffee sector, which entails the development of geographic “zones” around coffee washing stations (CWSs). Coffee farmers within a geographic zone must sell to a specific CWS; that CWS must only buy from designated farmers. The stated purpose of this policy is to better organize the industry, improve the relationship between CWSs and farmers, improve traceability of coffee, and reduce the role of middlemen (local traders who previously purchased coffee from farmers and then re-sold it to CWSs). Looking back on the first year of the policy’s implementation, we ask the following questions. According to stakeholders, to what extent did zoning meet its goals? How did zoning affect coffee stakeholders, such as farmers, middlemen, cooperatives, and others? Finally, what—if any— solutions or modifications might improve the policy?

description: In 1999 Chenciner and Montgomery found a remarkably simple choreographic motion for the planar 3-body problem (see \cite{CM}). In this solution 3 equal masses travel on a eight shaped planar curve; this orbit is obtained minimizing the action integral on the set of simple planar choreographies with some special symmetry constraints. In this work our aim is to study the problem of $n$ masses moving in $\RR^d$ under an attractive force generated by a potential of the kind $1/r^α$, $α>0$, with the only constraint to be a simple choreography: if $q_1(t),...,q_n(t)$ are the $n$ orbits then we impose the existence of $x \in H^1_{2 π}(\RR,\RR^d)$ such that $q_i(t)=x(t+(i-1) τ), i=1,...,n, t \in \RR, $ where $τ= 2π/ n$. In this setting, we first prove that for every $d,n \in \NN$ and $α>0$, the lagrangian action attains its absolute minimum on the planar circle. Next we deal with the problem in a rotating frame and we show a reacher phenomenology: indeed while for some values of the angular velocity minimizers are still circles, for others the minima of the action are not anymore rigid motions.

description: The EU has signed new agreements with Ukraine, Moldavia, and Ukraine, the so-called Deep and Comprehensive Free Trade Agreement (DCFTA). This policy brief only focuses on Georgia to exemplify the mythology and some important specifics of the participating countries that differ somewhat, but are important for assessing the impact. The agreement with Georgia became effective in September 2016; therefore, accurate estimation of the quantified effects was delayed for some time. This policy brief focusses on the free trade agreement on agricultural products. Georgia benefits from trade preferences for import to the EU and the EU likewise from exports to Georgia. It is foreseen that tariffs will be abolished completely in the future, but at present it is only Georgia which has abolished tariffs for imports from the EU. The EU has only reduced the World Trade Organization (WTO) bounded rates and, in addition, it still applies the so-called entry price system and even quotas for imports of garlic. Effects on trade might be important because the EU still highly protects agricultural imports and thus the standard of living for the 50 percent of Georgians living mainly from farming may improve. The findings are that Georgia may gain in total, if traders live in Georgia. The gain results from both redirection of Georgian exports from other destinations and additional exports of Georgian products. These additional exports to the EU may be replaced by additional imports from low price suppliers on the world market.

description: We present a method for proving the existence of symmetric periodic, heteroclinic or homoclinic orbits in dynamical systems with the reversing symmetry. As an application we show that the Planar Restricted Circular Three Body Problem (PCR3BP) corresponding to the Sun-Jupiter-Oterma system possesses an infinite number of symmetric periodic orbits and homoclinic orbits to the Lyapunov orbits. Moreover, we show the existence of symbolic dynamics on six symbols for PCR3BP and the possibility of resonance transitions of the comet. This extends earlier results by Wilczak and Zgliczynski - Heteroclinic Connections between Periodic Orbits in Planar Restricted Circular Three Body Problem - A Computer Assisted Proof, Commun. Math. Phys. 234, 37-75 (2003).

Merger motives and target valuation : A survey of evidence from CFOs

description: This study provides insights about the motives for mergers and acquisitions (M&As) as well as divestitures and the practices used to value targets during 1990-2001. The survey evidence shows that the primary motivation for M&As is to achieve operating synergies while the top-ranked reason for divestitures is to increase focus. The results also show that most firms believe diversification is a justifiable motive for acquisitions most notably as a means of reducing losses during economic downturns. Discounted cash flow methods dominate market multiples as the preferred approach for valuing both publicly-held and closely-held companies. Perhaps the most surprising finding is that although firms often define merger cash flows as the equity cash flows from the target, the discount rate used by acquiring firms is their own WACC rather than the targets’ cost of equity. This finding reflects one of the most persistent bad practices in valuing M&As and might lead to overpayment to targets. [G34]

description: The quantum walk formalism is a widely used and highly successful framework for modeling quantum systems, such as simulations of the Dirac equation, different dynamics in both the low and high energy regime, and for developing a wide range of quantum algorithms. Here we present the circuit-based implementation of a discrete-time quantum walk in position space on a five-qubit trapped-ion quantum processor. We encode the space of walker positions in particular multi-qubit states and program the system to operate with different quantum walk parameters, experimentally realizing a Dirac cellular automaton with tunable mass parameter. The quantum walk circuits and position state mapping scale favorably to a larger model and physical systems, allowing the implementation of any algorithm based on discrete-time quantum walks algorithm and the dynamics associated with the discretized version of the Dirac equation.

description: Cirrhotic patients have an increased risk of bleeding and thromboembolic events, with platelets being involved as key players in both situations. The impact of peripheral versus central blood sampling on platelet activation remains unclear. In 33 cirrhotic patients, we thus analyzed platelet function in peripheral (P) and central (C) blood samples. Platelet surface expression of P-selectin, activated glycoprotein (GP) IIb/IIIa, and leukocyte-platelet aggregate formation were measured by flow cytometry in response to different agonists: thrombin receptor-activating peptide-6, adenosine diphosphate, collagen-related peptide (CrP), epinephrine, AYPGKF, Pam3CSK4, and lipopolysaccharide. Unstimulated platelet surface expression of P-selectin (p = .850) and activated GPIIb/IIIa (p = .625) were similar in peripheral and central blood samples. Stimulation with various agonists yielded similar results of platelet surface expression of P-selectin and activated GPIIb/IIIa in peripheral and central samples, except for CrP-inducible expression of activated GPIIb/IIIa (median fluorescence intensity, MFI in P: 7.61 [0.00–24.66] vs. C: 4.12 [0.00–19.04], p Abbreviations: ACLD: advanced chronic liver disease; ADP: adenosine diphosphate; ALD: alcoholic liver disease; AYPGKF: PAR-4 agonist AYPGKF; CrP: collagen related protein; EPI: epinephrine; FACS: fluorescence-activated cell sorting; GP: glycoprotein; HVPG: hepatic venous pressure gradient; IQR: interquartile range; LPS: lipopolysaccharide; LSM: liver stiffness measurement; MFI: median fluorescence intensity; NAFLD: nonalcoholic fatty liver disease; PAM: lipopeptide Pam3CSK4; PAR: protease-activated receptor; PBS: phosphate-buffered saline; PH: portal hypertension; TIPS: transjugular intrahepatic portosystemic stent shunt; TLR: toll-like receptor; TRAP-6: thrombin receptor-activator peptide-6; vWF: von Willebrand factor

description: Tourism is promoted as an environmentally beneficial activity for Caribbean economies. Yet, degradation still occurs and more integrated policy approaches are needed. Using Q-methodology within a social-ecological system (SES) framework, we quantified the importance of various policy issues to stakeholders in Providenciales, Turks and Caicos Islands, where tourism produces 77% of its GDP. Stakeholders agree Providenciales’ economy benefits from a healthy marine environment, but disagree over which SES drivers are functionally important. Our results show that Q-methodology is a robust tool for informing the policy-making process and quantifying stakeholder views in a tourism-dependent economy.
