description: We study analytically the spacetime geometry of the black-hole formation and evaporation. As a simplest model of the collapse, we consider a spherical thin shell, and take the back-reaction from the negative energy of the quantum vacuum state. For definiteness, we will focus on quantum effects of s-waves. We obtain an analytic solution of the semi-classical Einstein equation for this model, that provides an overall description of the black hole geometry form the formation to evaporation. As an application of this result, we find its interesting implication that, after the collapsing shell enters the apparent horizon, the proper distance between the shell and the horizon remains as small as the Planck length even when the difference in their areal radii is of the same order as the Schwarzschild radius. The position of the shell would be regarded as the same place to the apparent horizon in the semi-classical regime of gravity.

description: The self-energy and vertex QED radiative corrections (Z alpha^2 f(Z alpha)) are shown to give a large negative contribution to the parity nonconserving (PNC) amplitude in heavy atoms. The correction -0.7(2)% found for the 6s-7s PNC amplitude in Cs brings the experimental result for this transition into agreement with the standard model. The calculations are based on a new identity that expresses the radiative corrections to the PNC matrix element via corrections to the energy shifts induced by the finite nuclear size.

description: Research on the impact of smallholder contract-farming largely focuses on exportoriented high-value commodities. Little is known about the possibility of contract-farming for upgrading in staple food chains. While theoretical insights predict contract-farming to be infeasible for lower-value staple food crops, empirical evidence from such sectors is extremely scarce. In this paper, we provide evidence on smallholder contract-farming in the rice sector in Benin. We use cross-sectional household data and propensity score matching methods to analyze the impact of contract-farming on selected farm performance indicators. The findings indicate that contract-farming has a positive impact on rice productivity and income.

description: This study examines the relationship between policy, market access, country governance indicators and food production in 41 African countries. Based on a cross-country panel sample, a fixed-random effect models is employed to test the hypothesis that beyond agricultural inputs and macroeconomic reforms other exogenous factors could foster food production. Our findings show that improving food-agricultural inputs enhance production, while conflicts, food aid and geographic location such as landlocked countries negatively affect food production. Exogenous factors influencing production response include rainfall, market access, and education. Both governance and education can indirectly improve food production by enhancing growth, through investment in infrastructures, and human capital.

description: Starting from the non-supersymmetric, tachyon-free orientifold of type 0 string theory, we construct four-dimensional brane world models with D6-branes intersecting at angles on internal tori. They support phenomenologically interesting gauge theories with chiral fermions. Despite the theory being non-supersymmetric the perturbative scalar potential induced at leading order is shown to stabilize geometric moduli, leaving only the dilaton tadpole uncanceled. As an example we present a three generation model with gauge group and fermion spectrum close to a left-right symmetric extension of the Standard Model.

Evolution of atmospheric escape in close-in giant planets and their associated Ly$α$ and H$α$ transit predictions

description: Strong atmospheric escape has been detected in several close-in exoplanets. As these planets consist mostly of hydrogen, observations in hydrogen lines, such as Ly-alpha and H-alpha, are powerful diagnostics of escape. Here, we simulate the evolution of atmospheric escape of close-in giant planets and calculate their associated Ly-alpha and H-alpha transits. We use a one-dimensional hydrodynamic escape model to compute physical properties of the atmosphere and a ray-tracing technique to simulate spectroscopic transits. We consider giant (0.3 and 1M_jup) planets orbiting a solar-like star at 0.045au, evolving from 10 to 5000 Myr. We find that younger giants show higher rates of escape, owing to a favourable combination of higher irradiation fluxes and weaker gravities. Less massive planets show higher escape rates (1e10 -- 1e13 g/s) than those more massive (1e9 -- 1e12 g/s) over their evolution. We estimate that the 1-M_jup planet would lose at most 1% of its initial mass due to escape, while the 0.3-M_jup planet, could lose up to 20%. This supports the idea that the Neptunian desert has been formed due to significant mass loss in low-gravity planets. At younger ages, we find that the mid-transit Ly-alpha line is saturated at line centre, while H-alpha exhibits transit depths of at most 3 -- 4% in excess of their geometric transit. While at older ages, Ly-alpha absorption is still significant (and possibly saturated for the lower mass planet), the H-alpha absorption nearly disappears. This is because the extended atmosphere of neutral hydrogen becomes predominantly in the ground state after ~1.2 Gyr.

Time Domain SAR Processing with GPUs for Airborne Platforms
Creators: name: Lagoy, Dustin
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: A time-domain backprojection processor for airborne synthetic aperture radar (SAR) has been developed at the University of Massachusetts’ Microwave Remote Sensing Lab (MIRSL). The aim of this work is to produce a SAR processor capable of addressing the motion compensation issues faced by frequency-domain processing algorithms, in order to create well focused SAR imagery suitable for interferometry. The time-domain backprojection algorithm inherently compensates for non-linear platform motion, dependent on the availability of accurate measurements of the motion. The implementation must manage the relatively high computational burden of the backprojection algorithm, which is done using modern graphics processing units (GPUs), programmed with NVIDIA’s CUDA language. An implementation of the Non-Equispaced Fast Fourier Transform (NERFFT) is used to enable efficient and accurate range interpolation as a critical step of the processing. The phase of time- domain processed imagery is dif erent than that of frequency-domain imagery, leading to a potentially different approach to interferometry. This general purpose SAR processor is designed to work with a novel, dual-frequency S- and Ka-band radar system developed at MIRSL as well as the UAVSAR instrument developed by NASA’s Jet Propulsion Laboratory. These instruments represent a wide range of SAR system parameters, ensuring the ability of the processor to work with most any airborne SAR. Results are presented from these two systems, showing good performance of the processor itself.

description: Common ragweed (Ambrosia artemisiifolia) is a neophyte from North America that has spread rapidly throughout Europe. Because the pollen of common ragweed is highly allergic, many countries have adopted containment and mitigation measures. The neophyte has only recently established flowering populations in Sweden. We use this well documented case to study the early impacts of an invasive species on human health. Our identification strategy relies on spatial and temporal variation in common ragweed populations and health data for 1998-2011, applying panel-data estimation techniques. To ensure the robustness of our findings, we test and correct for heteroskedasticity and autocorrelation. Our estimates show that an invasive species still in its lag phase can yet have adverse impacts on human health.
Effective neutrino masses in KATRIN and future tritium beta-decay experiments

description: Past and current direct neutrino mass experiments set limits on the so-called effective neutrino mass, which is an incoherent sum of neutrino masses and lepton mixing matrix elements. The electron energy spectrum which neglects the relativistic and nuclear recoil effects is often assumed. Alternative definitions of effective masses exist, and an exact relativistic spectrum is calculable. We quantitatively compare the validity of those different approximations as function of energy resolution and exposure in view of tritium beta decays in the KATRIN, Project 8 and PTOLEMY experiments. Furthermore, adopting the Bayesian approach, we present the posterior distributions of the effective neutrino mass by including current experimental information from neutrino oscillations, beta decay, neutrinoless double-beta decay and cosmological observations. Both linear and logarithmic priors for the smallest neutrino mass are assumed.

description: Results from the nu_tau appearance search in a neutrino beam using the full NOMAD data sample are reported. A new analysis unifies all the hadronic tau decays, significantly improving the overall sensitivity of the experiment to oscillations. The "blind analysis" of all topologies yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90% C.L. allowed region in the sin^2(2theta)-Delta m^2 plane which includes sin^2(2theta)<3.3 x 10^{-4} at large Delta m^2 and Delta m^2 < 0.7 eV^2/c^4 at sin^2(2theta)=1. The corresponding contour in the nu_e->nu_tau oscillation hypothesis results in sin^2(2theta)<1.5 x 10^{-2} at large Delta m^2 and Delta m^2 < 5.9 eV^2/c^4 at sin^2(2theta)=1. We also derive limits on effective couplings of the tau lepton to nu_mu or nu_e.

description: CPT violation in the neutrino sector, suggested as a new way to reconcile different neutrino anomalies, induces at the radiative level observable effects among charged leptons, where high-precision tests of the CPT symmetry are available. We show that, in the models with heavy right-handed Majorana neutrinos, constraints imposed by these experiments require CPT violation in neutrino spectrum be suppressed to a level undetectable for any conceivable neutrino experiment. We find that the CPT violation in the neutrino sector may evade indirect constraints only at the expense of light right-handed neutrinos with small Yukawa couplings to the Standard Model sector or by allowing non-locality well below the electroweak scale.

The Role of Placemaking in Sustainable Planning: A Case Study of the East Side of Cleveland, Ohio
Creators: name: Lang, Sarah
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: The notion of placemaking and sustainability are central to planning practice. However, is there a connection between the goals of sustainability and the impacts of placemaking initiatives? The ultimate goal of sustainable planning is the creation of a sustainable community which include the defining features of a healthy climate and environment, social wellbeing, and economic security. Yet, sustainable planning is heavily focused on the environment. Placemaking initiatives focus on underutilized space, permanently or temporarily highlighting location, locale, and sense, the three realms of place. In attempt to answer whether placemaking can contribute to sustainable planning, this research focuses on the case study of the east side neighborhoods of Cleveland, Ohio and three placemaking initiatives which take place in those neighborhoods. Placemaking attendees were surveyed on their perspectives of the impact that the placemaking initiative has on the community. After coding the responses for common themes, these themes were related back to the larger defining features of a sustainable community. It was found that placemaking can be used to support the social and economic realms within sustainable planning and communities. The main characteristics which make these initiatives successful are free and open to the public, expression of uniqueness, and the support of local businesses. Placemaking offers benefits to both community and non-community members. Ultimately, placemaking is a beneficial tool that should be utilized by planners to aid in sustainable planning.

Volatiles in Subglacially Erupted Basaltic Glasses and Their Use in Reconstructing Paleo-Ice Thicknesses
Creators: name: Lee, Carver
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Volatile concentrations in basaltic tuyas, edifices that form during a subglacial eruption and remain once the ice sheet has retreated, have been used to calculate the thickness of the overlying ice sheet at the onset of the eruption (Tuffen, 2010). However, subglacial eruptions are complex events and this technique does not always provide a clear answer (Schopka et al., 2006; Edwards et al., 2009). The purpose of this research is to evaluate this technique and investigate constraints on the quality of data collected by attempting to calculate the minimum ice thickness under which Hlöðufell, a tuya in south-central Iceland, erupted.
Hlöðufell is a Holocene tuya located in the Western Rift Zone of Iceland, 9 km south from the modern edge of Langjökull ice cap. Dissolved H2O concentrations were measured using Fourier transform infrared spectroscopy (FTIR) and quenching pressures were calculated using the VolatileCalc pressure-solubility model (Newman and Lowenstern, 2002). Overlying ice thickness was calculated by relating quenching pressures, the density of ice, and the elevation of the sample.
Water concentrations range from 0.068 –to 0.478 wt. % H2O, representing pressures ranging from 0.66 to 24.72 bars. These pressures represent ice thicknesses between 0 and 268 m thick. The minimum ice thickness level is represented in the lithofacies of the tuya by the passage zone, the transition between subaerial and subaqueous flows. The minimum ice thickness for Hlöðufell is ~ 500 m, much thicker than this study calculated using water concentrations. This indicates that the volatile concentrations in the basaltic glasses at Hlöðufell do not record the accurate quenching pressure. We interpret the overall low water concentrations to mean that our samples must have degassed at or close to atmospheric pressures at higher elevations, and flowed downslope into areas of thicker ice or deeper melt-water before quenching. These results show that subglacial eruptions and degassing processes are complex and variable and require further investigation.

 Chuneola Woltereck, 1909: 152. Bowman & Gruner 1973: 19. Vinogradov et al. 1982: 91–92.
 Type species. Chuneola paradoxa Woltereck, 1909 by monotypy. The unique type, a juvenile measuring just less than 7 mm (judging by Woltereck’s drawing) could not be found in any major European museum and is considered lost. Fortunately, this is a very distinctive species readily distinguished by Woltereck’s description and figure. The type locality is the Indian Ocean [06°38.5’S 70° 58° 1’E]; Valdivia Stn. 225.
 Diagnosis. As with the characters of the family.
Three species.
 Sexual dimorphism. Sexual dimorphism is not very marked in Chuneola. Apart from the fact that females have oostegites and males have small genital papillae the main difference seems to be that females have a slightly more inflated pereon.
 Remarks. This is a very distinctive genus, unlike any other in the superfamily. Unusual characters of note are the relatively large mouthparts, the lack of a mandibular palp and molar, the relatively shorter first antennae with only two small articles terminal to the callynophore, the reduced second antennae, the partly retractile dactyls of the gnathopods and the spoon-shaped formation and retractile dactyls of pereopods 3 & 4. The structure of the mouthparts provides a link to the Scinoidea but most of the other characters are more aligned with the Lanceoloidea.

description: N131 is a typical infrared dust bubble showing an expanding ringlike shell. We study what kinds of CO line ratios can be used to trace the interaction in the expanding bubble. We carry out new $\rm CO\,(3-2)$ observations towards bubble N131 using the JCMT 15-m telescope, and derive line ratios by combining with our previous $\rm CO\,(2-1)$ and $\rm CO\,(1-0)$ data from the IRAM 30-m telescope observations. To trace the interaction between the molecular gas and the ionized gas in the HII region, we use RADEX to model the dependence of CO line ratios on kinetic temperature and H$_2$ volume density, and examine the abnormal line ratios based on other simulations. We present $\rm CO\,(3-2)$, $\rm CO\,(2-1)$, and $\rm CO\,(1-0)$ integrated intensity maps convolved to the same angular resolution (22.5$"$). The three different CO transition maps show apparently similar morphology. The line ratios of $W_{\rm CO\,(3-2)}$/$W_{\rm CO\,(2-1)}$ mostly range from 0.2 to 1.2 with a median of $0.54\pm0.12$, while the line ratios of $W_{\rm CO\,(2-1)}$/$W_{\rm CO\,(1-0)}$ range from 0.5 to 1.6 with a median of $0.84\pm0.15$. The high CO line ratios $W_{\rm CO\,(3-2)}$/$W_{\rm CO\,(2-1)}\gtrsim 0.8 $ and $W_{\rm CO\,(2-1)}$/$W_{\rm CO\,(1-0)}\gtrsim 1.2$ are beyond the threshold predicted by numerical simulations based on the assumed density-temperature structure for the inner rims of ringlike shell, where are the compressed areas in bubble N131. These high CO integrated intensity ratios, such as $W_{\rm CO\,(3-2)}$/$W_{\rm CO\,(2-1)}\gtrsim0.8$ and $W_{\rm CO\,(2-1)}$/$W_{\rm CO\,(1-0)}\gtrsim1.2$, can be used as a tracer of gas compressed regions with a relatively high temperature and density. This further suggests that the non-Gaussian part of the line-ratio distribution can be used to trace the interaction between the molecular gas and the hot gas in the bubble.

description: Thermodynamic properties of the SU($n$) Heisenberg model in one dimension is studied by means of high-temperature expansion for arbitrary $n$. The specific heat up to $O[(βJ)^{23}]$ and the correlation function up to $O[(βJ)^{18}]$ are derived with $βJ$ being the antiferromagnetic exchange in units of temperature. It is found for $n>2$ that the specific heat shows a shoulder in the high-temperature side of a peak. The origin of this structure is clarified by deriving the temperature dependence of the correlation function. With decreasing temperature, the short-range correlation with two-site periodicity develops first, and then another correlation with $n$-site periodicity at lower temperature. This behavior is in contrast to that of the inverse square interaction model, where the specific heat shows a single peak according to the exact solution. Our algorithm has an advantage that neither computational time nor memory depends on the multiplicity $n$ per site; the series coefficients are obtained as explicit functions of $n$.

Subjects: Community/Rural/Urban Development

description: Paper presents the main changes brought by the new EU Rural Development Regulation and discusses the main open issues that refer to its implementation in the period of the New Financial Perspective (NFP) of the EU (2007-2013). The paper attempts to assess the significance of these changes on the future implementation of rural development in Slovenia. The future allocation of funds for Rural Development from the Community budget to Slovenia is not likely to increase significantly. Public expenditure in this policy field is also highly dependent from the future status of Slovenia in the EU Cohesion policy. In terms of implementation, the main risks refer to the unbalanced expenditure for various groups of rural development measures in Slovenia. This imbalance could impair the future implementation of some newly introduced rural development measures (e.g. agri-environmental measures, compliance with the Community standards). The paper states that these risks can be controlled with careful policy programming. In the long term, Slovenia would benefit from a better balancing of rural development measures.

description: With the tremendous growth of videos over the Internet, video thumbnails, providing video content previews, are becoming increasingly crucial to influencing users' online searching experiences. Conventional video thumbnails are generated once purely based on the visual characteristics of videos, and then displayed as requested. Hence, such video thumbnails, without considering the users' searching intentions, cannot provide a meaningful snapshot of the video contents that users concern. In this paper, we define a distinctively new task, namely sentence specified dynamic video thumbnail generation, where the generated thumbnails not only provide a concise preview of the original video contents but also dynamically relate to the users' searching intentions with semantic correspondences to the users' query sentences. To tackle such a challenging task, we propose a novel graph convolved video thumbnail pointer (GTP). Specifically, GTP leverages a sentence specified video graph convolutional network to model both the sentence-video semantic interaction and the internal video relationships incorporated with the sentence information, based on which a temporal conditioned pointer network is then introduced to sequentially generate the sentence specified video thumbnails. Moreover, we annotate a new dataset based on ActivityNet Captions for the proposed new task, which consists of 10,000+ video-sentence pairs with each accompanied by an annotated sentence specified video thumbnail. We demonstrate that our proposed GTP outperforms several baseline methods on the created dataset, and thus believe that our initial results along with the release of the new dataset will inspire further research on sentence specified dynamic video thumbnail generation.

description: We study a dark energy cubic bi-Galileons field model based on truncation of the recently proposed generalized covariant multi-Galileons model. We investigate the cosmological dynamic of the model by the theory of dynamical systems through the analysis of the properties of the fixed points in each cosmological epoch. We show the existence of two tracker solutions, one of which is that of the cubic single Galileon model and the other solution is the signature of the second Galileon field. Exploiting the competition between the two Galileon fields, we find a dark energy solution that avoids the approach to the tracker solution with dark energy equation of state $w_{DE}=-2$ during the matter epoch which is disfavored by the observational data. We study also the growth rate of matter perturbations. Using recent $fσ_{8}$ redshift space distortion (RSD) and model-independent observational Hubble (OHD) data sets, we place observational constraints on the coupling constant and cosmological parameters of the bi-Galileons model through Monte Carlo numerical method based on the Metropolis-Hastings algorithm. We find that the amplitude of growth matter fluctuations is consistent with the Planck15 data and ease the tension between early and later clustering, and fits better the data from the DES survey over the data from KiDS-450 survey. We also find that the best fit value for the Hubble constant is compatible with new measurements of Cepheid-supernovae distance scale. Finally, we perform a model selection through the Bayes factor and found that the bi-Galileons model is disfavored in comparison to the $Λ$CDM model, but slightly preferred to $w$CDM model.

description: Following a suggestion of Kostelecky et al. we have evaluated a test of CPT and Lorentz invariance from the microwave spectroscopy of muonium. Hamiltonian terms beyond the standard model violating CPT and Lorentz invariance would contribute frequency shifts $δν_{12}$ and $δν_{34}$ to $ν_{12}$ and $ν_{34}$, the two transitions involving muon spin flip, which were precisely measured in ground state muonium in a strong magnetic field of 1.7 T. The shifts would be indicated by anti-correlated oscillations in $ν_{12}$ and $ν_{34}$ at the earth's sidereal frequency. No time dependence was found in $ν_{12}$ or $ν_{34}$ at the level of 20 Hz, limiting the size of some CPT and Lorentz violating parameters at the level of $2\times10^{-23}$ GeV, representing Planck scale sensitivity and an order of magnitude improvement in sensitivity over previous limits for the muon.

description: The paper presents the newly developed methodology for defining a socio-economic structure of farms, which was developed to analyse the socio-economic structure of Slovene farms based on data from Agricultural holdings census performed in year 2000. Developed methodology enables to define four main socio-economic types of farms: fulltime, part-time, supplementary and aged, based on data about employment status and work engagement of the core members of the farm’s family. The results are showing that among the farm types there is the highest share of supplementary farms, followed by part-time farms. The share of full-time farms is significantly lower from previous two. Comparison to previous census shows the significant rise of supplementary farms on account of the part-time farms.

description: Spreading the information over all coefficients of a representation is a desirable property in many applications such as digital communication or machine learning. This so-called antisparse representation can be obtained by solving a convex program involving an $\ell_\infty$-norm penalty combined with a quadratic discrepancy. In this paper, we propose a new methodology, dubbed safe squeezing, to accelerate the computation of antisparse representation. We describe a test that allows to detect saturated entries in the solution of the optimization problem. The contribution of these entries is compacted into a single vector, thus operating a form of dimensionality reduction. We propose two algorithms to solve the resulting lower dimensional problem. Numerical experiments show the effectiveness of the proposed method to detect the saturated components of the solution and illustrates the induced computational gains in the resolution of the antisparse problem.
An Adult Zebrafish Brain Atlas To Investigate Shh Mediated Cell-Cell Signaling In Neurogenic Zones
Creators: name: Lutservitz, Alyssa P
Publisher: name: University of Massachusetts Amherst

description: Adult neurogenesis occurs in proliferative zones of the brain that contain neural progenitor cell populations capable of differentiating into specific cell types. However, we remain limited in our understanding of the signals that regulate neural progenitor cell proliferation and differentiation in adults. Recently zebrafish (Danio rerio) have emerged as an excellent model for studying the molecular mechanisms behind adult neurogenesis, because sixteen proliferative zones remain active in the adult brains. Thousands of fluorescent transgenic reporter lines have been generated in zebrafish that reveal gene expression patterns of cell-cell signaling systems, some of which may regulate neurogenesis in these brain regions. Using a new tissue clearing technique and whole brain imaging with fluorescent light sheet microscopy (FLSM) we have generated the first 3-Dimensional atlas of gene expression in an intact adult zebrafish brain. So far we have created a reference brain image and have aligned the expression patterns from three transgenic lines. This work is a preliminary step in the generation of a new, open access brain atlas called the Zebrafish Adult Brain Browser (ZABB). While generating this atlas we focused on documenting the adult brain regions responsive to Sonic Hedgehog (Shh), a cell-cell signaling system known to regulate neurogenesis during embryonic development. We used two Shh-reporter lines to create another atlas comparing reporter transgene expression in whole brain and sectioned tissue to the expression of the Hedgehog (Hh) target gene ptch2 using in situ hybridization. We show that the reporter lines reveal different Hh responsive domains, but together identify fourteen Hh responsive regions in the brain, nine of which are known proliferative zones. Thus, it appears that subsets of both proliferating neural progenitors and non-proliferative cells remain Hh responsive in adult brains. Our data suggests that Hh signaling contributes to the regulation of neural progenitor cells in nine of the sixteen proliferative zones. Uncovering the molecular mechanisms behind adult neurogenesis and forming a greater understanding of adult neural stem cell regulation has the potential to influence the treatment of many neurodegenerative diseases and cancers.

description: We discuss a novel cold dark matter candidate which is formed from the ordinary quarks during the QCD phase transition when the axion domain wall undergoes an unchecked collapse due to the tension in the wall. If a large number of quarks is trapped inside the bulk of a closed axion domain wall, the collapse stops due to the internal Fermi pressure. In this case the system in the bulk, may reach the critical density when it undergoes a phase transition to a color superconducting phase with the ground state being the quark condensate, similar to the Cooper pairs in BCS theory. If this happens, the new state of matter representing the diquark condensate with a large baryon number $B \sim 10^{32}$ becomes a stable soliton-like configuration. Consequently, it may serve as a novel cold dark matter candidate.

description: A straightforward and general method has been developed for the synthesis of chalcone derivatives by a Claisen-Schmidt reaction in the presence of PPh3/I2 in 1,4-dioxane under reflux temperatures. With the condensation of the aromatic ketone and aldehyde occurring at non-strongly alkaline conditions, our proposed method significantly expands the range of applicable substrates, especially for groups that are unstable under alkaline conditions.
