description: Analysis of livelihood strategies can aid to understand and resolve problems associated with vulnerability to poverty and food security. This paper aims to identify and describe the changes in rural livelihood activities by using household data for 2013 and 2014 collected in Stung Treng, Cambodia. We use the same variables and estimate different clusters for both the years. The paper concludes that despite the lag of only one year, there are noticeable changes in livelihood strategies. Firstly, we find a group of transition farmers in 2014 that is composed of households that are witnessing a shift towards commercialization. They invest and consume more than subsistence farmers. Secondly, there is a greater diversification in activities amongst the groups. Most households practice multiple activities. Lastly, with regards to self-employment, there has been a shift from agriculture and the production sector to services and crafts. All of the above changes can be deemed as positive as there is a gradual movement away from more vulnerable sectors. Accordingly, households that participate in livelihood activities related to agriculture and natural resource extraction are most affected by shocks and face the highest vulnerability to poverty. The paper additionally highlights some concerns such as a decline in availability of extracted products such as the fish stock which are expected to negatively impact on these more vulnerable rural households in the medium and longer term. Furthermore, the state of education is dismal and needs attention. Therefore, policy makers need to consider these issues while addressing rural poverty.

description: We introduce a new class of two-stage stochastic uncapacitated facility location problems under system nervousness considerations. The location and allocation decisions are made under uncertainty, while the allocation decisions may be altered in response to the realizations of the uncertain parameters. A practical concern is that the uncertainty-adaptive second-stage allocation decisions might substantially deviate from the corresponding pre-determined first-stage allocation decisions, resulting in a high level of nervousness in the system. To this end, we develop two-stage stochastic programming models with restricted recourse that hedge against undesirable values of a dispersion measure quantifying such deviations. In particular, we control the robustness between the corresponding first-stage and scenario-dependent recourse decisions by enforcing an upper bound on the Conditional Value-at-Risk (CVaR) measure of the random CVaR-norm associated with the scenario-dependent deviations of the recourse decisions. We devise exact Benders-type decomposition algorithms to solve the problems of interest. To enhance the computational performance, we also develop efficient combinatorial algorithms to construct optimal solutions of the Benders cut generation subproblems, as an alternative to using an off-the-shelf solver. The results of our computational study demonstrate the value of the proposed modeling approaches and the effectiveness of our solution methods.

description: We study 6d superconformal field theories (SCFTs) compactified on a circle with arbitrary twists. The theories obtained after compactification, often referred to as 5d Kaluza-Klein (KK) theories, can be viewed as starting points for RG flows to 5d SCFTs. According to a conjecture, all 5d SCFTs can be obtained in this fashion. We compute the Coulomb branch prepotential for all 5d KK theories obtainable in this manner and associate to these theories a smooth local genus one fibered Calabi-Yau threefold in which is encoded information about all possible RG flows to 5d SCFTs. These Calabi-Yau threefolds provide hitherto unknown M-theory duals of F-theory configurations compactified on a circle with twists. For certain exceptional KK theories that do not admit a standard geometric description we propose an algebraic description that appears to retain the properties of the local Calabi-Yau threefolds necessary to determine RG flows to 5d SCFTs, along with other relevant physical data.

description: Dark energy models which alter the relative scaling behavior of dark energy and matter could provide a natural solution to the cosmic coincidence problem - why the densities of dark energy and dark matter are comparable today. A generalized class of dark energy models is introduced which allows non-canonical scaling of the ratio of dark matter and dark energy with the Robertson-Walker scale factor a(t). Upcoming observations, such as a high redshift supernova survey, application of the Alcock-Paczynski test to quasar pairs, and cluster evolution, will strongly constrain the relative scaling of dark matter and dark energy as well as the equation of state of the dark energy. Thus, whether there actually is a coincidence problem, and the extent of cosmic coincidence in the universe's recent past can be answered observationally in the near future. Determining whether today is a special time in the history of the universe will be a SNAP.

description: The bimodal mesoporous silicas nanoparticles (BMMs) with small size of 20–50 nm and mesoporous silicas nanoparticles (MSNs) with large sizes from 80 nm to 280 nm were synthesized using sol–gel method. These functionalized mesoporous silicas composites with different sizes were acquired by environmental responsive (pH/temperature) copolymer coated onto the mesoporous silica hosts via the seed polymerization method. The structural features and textual parameters of resultant samples were characterized by X-ray diffraction, scanning electron microscope, transmission electron microscope, N2 adsorption–desorption isotherms, thermogravimetric analyses, FT-IR, DLS, SAXS technologies, indicating that copolymer was successfully coated on the mesoporous silicas. Meanwhile, functionalized mesoporous silicas composites as drug carries were used to explore the pH/temperature responsive efficiency. These results showed that compared with the blank mesoporous silicas nanoparticles, mesoporous silicas composites realized a reduced initial burst release. In particular, the particle size of mesoporous silicas composites effects on the release behaviors were found that the smaller composite nanoparticles with short mesoporous channels exhibited highly pH/temperature response compared to the larger composite nanoparticles with long mesoporous channels. Meanwhile, their IBU-release kinetic profiles followed Korsmeyer–Peppas model. Moreover, the toxicity of mesoporous silicas composites was evaluated in vitro. It found that the particle size of mesoporous silicas composites was essential for its cytotoxicity.

Modified-Entropy Models for the Intracluster Medium

description: We present a set of cluster models that link the present-day properties of clusters to the processes that govern galaxy formation. These models treat the entropy distribution of the intracluster medium as its most fundamental property. Because convection strives to establish an entropy gradient that rises with radius, the observable properties of a relaxed cluster depend entirely on its dark-matter potential and the entropy distribution of its uncondensed gas. Guided by simulations, we compute the intracluster entropy distribution that arises in the absence of radiative cooling and supernova heating by assuming that the gas-density distribution would be identical to that of the dark matter. The lowest-entropy gas would then fall below a critical entropy threshold at which the cooling time equals a Hubble time. Radiative cooling and whatever feedback is associated with it must modify the entropy of that low-entropy gas, changing the overall entropy distribution function and thereby altering the observable properties of the cluster. Using some phenomenological prescriptions for entropy modification based on the existence of this cooling threshold, we construct a remarkably realistic set of cluster models. The surface-brightness profiles, mass-temperature relation, and luminosity-temperature relation of observed clusters all naturally emerge from these models. By introducing a single adjustable parameter related to the amount of intracluster gas that can cool within a Hubble time, we can also reproduce the observed temperature gradients of clusters and the deviations of cooling-flow clusters from the standard luminosity-temperature relation.

description: We have carried out molecular dynamics simulations of the crystallization of hard spheres modelling colloidal systems that are studied in conventional and space-based experiments. We use microscopic probes to investigate the effects of gravitational forces, polydispersity and of bounding walls on the phase structure. The simulations employed an extensive exclusive particle grid method and the type and degree of crystalline order was studied in two independent ways: by the structure factor, as in experiments, and through local rotational invariants. We present quantitative comparisons of the nucleation rates of monodisperse and polydisperse hard sphere systems and benchmark them against experimental results. We show how the presence of bounding walls leads to wall-induced nucleation and rapid crystallization and discuss the role of gravity on the dynamics of crystallization.

description: The electron cyclotron emission (ECE) in fusion devices is non-trivial to model in detail at frequencies well below the fundamental resonance where the plasma is optically thin. However, doing so is important for evaluating the background for microwave diagnostics operating in this frequency range. Here we present a general framework for estimating the ECE levels of fusion plasmas at such frequencies using ensemble-averaging of rays traced through many randomized wall reflections. This enables us to account for the overall vacuum vessel geometry, self-consistently include cross-polarization, and quantify the statistical uncertainty on the resulting ECE spectra. Applying this to ITER conditions, we find simulated ECE levels that increase strongly with frequency and plasma temperature in the considered range of 55-75 GHz. At frequencies smaller than 70 GHz, we predict an X-mode ECE level below 100 eV in the ITER baseline plasma scenario, but with corresponding intensities reaching keV levels in the hotter hybrid plasma scenario. Benchmarking against the SPECE raytracing code reveals good agreement under relevant conditions, and the predicted strength of X-mode to O-mode conversion induced by wall reflections is consistent with estimates from existing fusion devices. We discuss possible implications of our findings for ITER microwave diagnostics such as ECE, reflectometry, and collective Thomson scattering.

description: Non-alcoholic (NA) beer, a beverage that tastes like beer and contains no/little alcohol, has seen growing world-wide popularity as a potential substitute of beer. To elucidate consumer demand and profitability of NA beer, this study estimated price elasticities and price-cost margins of beer and NA beer at brand level in the case of Japan, using a structural demand model of differentiated products and a purchase data scanned by 30,000 consumers. According to the empirical result, NA beer demand is responsive to prices of some regular and premium beer brands as well as NA beer brands while beer demand is not responsive to NA beer prices. This implies that (1) some consumers of regular and premium beers consider NA beer as a substitute although NA beer consumers do not recognize beer as a replacement; (2) although low-malt, new-genre (alcoholic drinks with beer-like taste), and NA beers have some common product characteristics, consumers of low-malt and new-genre beers have different preference from that of NA beer consumers; (3) unless prices of NA beer brands increase, certain amount of demand for NA beer can be expected to remain irrespective of price levels of beer brands. Price-cost margins of producing NA beer were found to be similar to those of regular and new-genre beers while price-cost margins for premium beer were small and those for low-malt beer were large.

description: Trade elasticities are critical for price or structural change analysis. The Armington demand model is used to estimate trade elasticities, the country-of-origin bias, and the impact of the U.S. BSE outbreak on preferences. OLS estimation generates theoretically wrong signs, including a positive impact of U.S. BSE on other countries’ demand for imported beef. Results of a Bayesian hierarchical model show that import demand of countries that tend to import more beef from the U.S., such as Japan, Canada, Korea, and Russia, are affected more by the U.S. BSE outbreak than countries, such as the EU that tend not to import from the U.S.

description: This paper investigates the impact of the increased reaction rate constant due to tunneling effects on planet-forming disks. Our aim is to quantify the astrophysical implications of atom tunneling for simple molecules that are frequently used to infer disk structure information or to define the initial conditions for planet (atmosphere) formation. We explain the tunneling effect on reaction rates by using a scholarly example in comparison to previous UMIST2012 rate constants. In a chemical network with 1299 reactions, we identify all reactions that could show atom tunneling. We devise a simple formulation of reaction rate constants that overestimates tunneling and screen a standard T Tauri disk model for changes in species abundances. For those reactions found to be relevant, we find values of the most recent literature for the rate constants including tunneling and compare the resulting disk chemistry to the standard disk models. The rate constants in the UMIST2012 database in many cases already capture tunneling effects implicitly. A rigorous screening procedure identified three neutral-neutral reactions where atom tunneling could change simple molecule abundances. However, by adopting recent values of the rate constants of these reactions and due to the layered structure of planet-forming disks, the effects are limited to a small region where cold neutral-neutral chemistry dominates. Abundances of water close to the midplane snowline can increase by a factor of two at most compared to previous results with UMIST2012 rates. Observables from the disk surface, such as high excitation (> 500 K) water line fluxes, decrease by 60% at most when tunneling effects are explicitly excluded. On the other hand, disk midplane quantities relevant for planet formation such as the C-to-O ratio and also the ice-to-rock ratio are clearly affected by these gas-phase tunneling effects.

description: The decays of the $β$-delayed neutron emitters $^{137}$I and $^{95}$Rb have been studied with the total absorption $γ$-ray spectroscopy technique. The purity of the beams provided by the JYFLTRAP Penning trap at the ion guide isotope separator on-line facility in Jyväskylä allowed us to carry out a campaign of isotopically pure measurements with the decay total absorption $γ$-ray spectrometer, a segmented detector composed of eighteen NaI(Tl) modules. The contamination coming from the interaction of neutrons with the spectrometer has been carefully studied, and we have tested the use of time differences between prompt $γ$-rays and delayed neutron interactions to eliminate this source of contamination. Due to the sensitivity of our spectrometer, we have found a significant amount of $β$-intensity to states above the neutron separation energy that de-excite by $γ$-rays, comparable to the neutron emission probability. The competition between $γ$ de-excitation and neutron emission has been compared with Hauser-Feshbach calculations, and it can be understood as a nuclear structure effect. In addition, we have studied the impact of the $β$-intensity distributions determined in this work on reactor decay heat and reactor antineutrino spectrum summation calculations. The robustness of our results is demonstrated by a thorough study of uncertainties, and with the reproduction of the spectra of the individual modules and the module-multiplicity gated spectra. This work represents the state-of-the-art of our analysis methodology for segmented total absorption spectrometers.

description: We report on the quiescent spectrum measured with Chandra/ACIS-S of the transient, type-I X-ray bursting neutron star Aql X-1, immediately following an accretion outburst. The neutron star radius, assuming a pure hydrogen atmosphere and hard power-law spectrum, is $R_\infty$=13.4{+5}{-4} (d/5 \kpc) km. Based on the historical outburst record of RXTE/ASM, the quiescent luminosity is consistent with that predicted by Brown, Bildsten and Rutledge from deep crustal heating, lending support to this theory for providing a minimum quiescent luminosity of transient neutron stars. While not required by the data, the hard power-law component can account for 18+/-8% of the 0.5-10 keV thermal flux. Short-timescale intensity variability during this observation is less than 15% rms (3 sigma; 0.0001-1 Hz, 0.2-8 keV). Comparison between the Chandra spectrum and three X-ray spectral observations made between Oct 1992 and Oct 1996 find all spectra consistent with a pure H atmosphere, but with temperatures ranging from 145--168 eV, spanning a factor of 1.87+/-0.21 in observed flux. The source of variability in the quiescent luminosity on long timescales (greater than years) remains a puzzle. If from accretion, then it remains to be explained why the quiescent accretion rate provides a luminosity so nearly equal to that from deep crustal heating.

description: We examine the changing structure of retail food stores, direct marketing (DM), and its impact on farmers’ financial performance in the United States. We use a maximum simulated likelihood estimation with multinomial treatments and continuous measures of sales to accommodate the treatment effects relative to the base (no direct marketing). Our analyses indicate that on the changing structure of retail food stores, no direct marketing (base case) outlet is the most adopted channel by direct marketers compared to direct market to consumers only (Treatment-1), direct marketing to retailers only (Treatment-2), and direct marketing to both consumers and retailers (Treatment-3). We find that farmers who have chosen no direct marketing option show better earning performance compared to the other treatments or market outlets channel options from which earning decreases by 75%, 19%, and 11%, respectively under Treatment-1, T-Treatment-2 and Treatment-3 from 2008 to 2010. Direct marketers who are more likely to choose either Treatment 1-3 option relative to no direct marketing on the basis of their unobserved characteristics, choose direct marketing less and less.

description: The coexistence of a large herbivore community depends on the degree of overlap in the resource used by the different species composing it. We investigated the role of grass greenness, height, biomass and feeding patch status on feeding patch selection by ruminant black and blue wildebeest (Connochaetes gnou, Connochaetes taurinus), red hartebeest (Alcelaphus buselaphus) and non-ruminant plains zebra (Equus quagga) in a protected grassland in South Africa. Selection by ruminants was associated with grass greenness and grass height, <10 cm for black and blue wildebeest, and >11 cm for red hartebeest. The non-ruminant zebra were more generalist, but selected for wetlands in all seasons, as did red hartebeest and blue wildebeest. Each species modified its behaviour during the late dry season by searching more for biomass or accepting grass that was less green or longer. The presence of burnt patches did not affect patch selection by any study species. Accordingly, large herbivore resource use showed strong seasonal adaptations, wetlands were important for sustaining sympatric species in the study area, and none of the species used the exact same combination of resources.

 Morphology. Female — Idiosoma L 1809–2440; paired frontal plates (Fig. 6C), L/W 500/288, separated from each other by membranous integument; coxal field: L 619, W 1187, medial margin of Cx-III+IV concave, Cx-IV bearing one seta, posteromedial corner of Cx-IV extended with cleaver-shaped posterolaterally directed secondary sclerotization; genital field (Fig. 6A) L/W 197/263.

 Remarks. The third Hydrachna species collected from a pool near Gerdoig village resembles Hydrachna globosa (De Geer, 1778). Our specimens are assigned to the Oriental subspecies, H. globosa lacerata Lundblad, 1969, known only from a female from Burma (Lundblad 1969). Compared with the stem species, this subspecies has more broad and relatively short frontal plates, a more slender P-3 (L/H ratio 3.1) and extended posteromedial extensions of the fourth coxal plates. Additional information on the population variability of H. globosa lacerata, and the description of the male, are necessary to resolve the taxonomy of this taxon.
 Habitat. Standing waters (Fig. 8A).

description: This letter presents wide-field optical and and NIR UBVRI,Halpha,K' images of the galaxy M74 which were taken between 0.6-8.3 years before the discovery of the Type Ic SN2002ap. We have located the position of the SN on these images with an accuracy of 0.3''. We find no sign of a progenitor object on any of the images. The deepest of these images is the B-band exposure which has a sensitivity limit corresponding to an absolute magnitude of M_B <= -6.3. From our observed limits, we rule out as the progenitor all evolved states of single stars with initial masses greater than 20Msol unless the WR phase has been entered. Two popular theories for the origin of Type Ic SNe are the core collapse of massive stars when they are in the WR phase, or the core collapse of a massive star in an interacting binary which has had its envelope stripped through mass transfer. Our prediscovery images are sensitive only to the most luminous ~30% of WR stars, leaving a substantial fraction of typical WR stars as viable progenitors. The energetics measured from modelling the spectral evolution of SN 2002ap suggest an explosion of a 5Msol C+O core. While WR stars generally have measured final masses greater than this, the uncertainties associated with the explosion model, stellar evolutionary calculations and mass measurements suggest we cannot definitively rule out a WR star progenitor. The alternative scenario is that the progenitor was a star of initial mass 20-25Msol which was part of an interacting binary. We discuss future observations which will provide further constraints on the nature of the progenitor.
