description: “All Roads Lead Back to Amherst,” an exhibit of nature photographs by Annie (Fournier) Tiberio Cameron ’73, will be on display from September 15 through December 11, 2009, in the Integrated Sciences and Engineering Library at UMass Amherst (Lederle Graduate Research Center Lowrise, Floor 2).

Annie Tiberio Cameron came to UMass in 1969 to study Wildlife Biology. She has a B.S. in Environmental Education and did graduate work at North Adams State College, UMass Amherst, and Westfield State College. Tiberio Cameron has been a photography instructor at Bay Path College, Massachusetts Audubon Society, National Wildlife Federation, UMass Amherst, among others. Her photographs have been exhibited in New York, Michigan, New Mexico, and Texas, as well as New England. Her work has been published in Sierra Magazine, Mass. Audubon's Sanctuary Magazine, and other publications.

“I make 35mm color images that help me to reveal what I feel about the natural world: its colors shapes, textures, lines, and forms,” says Tiberio. “My background in science supports my visual expressions on film where my goal is to make a connection between myself and the observer. I try to make familiar and simple things in nature acquire the elegance that I see through my lenses.”

description: In this deliverable, we present updates of pan-European scenario results, together with selected highlights of European country-specific and region-specific scenario results, as well as consistent and coherent results on local community, neighbourhood and individual building level. The scope of this deliverable includes two main aspects: First, the final openENTRANCE scenario model runs were performed both at the pan-European level and at the level of individual European countries. This was done after making selective improvements to the input data and refinements to the energy system model GENeSYS MOD, based on the findings from the results of the “draft” energy system decarbonization scenario results at the pan-European level (Deliverable D3.1). Second, the development of consistent and coherent methods and algorithms to break down country-specific GENeSYS MOD modeling results across the different geographic aggregation levels to the smallest administrative unit level such as municipalities, districts, neighbourhoods, buildings, and finally to the individual end-user. To our knowledge, there has not yet been the ambition to conduct concrete energy system analyses to achieve specific climate goals across all levels of aggregation in a consistent and very concrete manner down to the individual end user. These kinds of “last mile” to end-user analyses, presented in Deliverable D3.2, are becoming increasingly important to get a sense of how to respond in very concrete ways to future climate challenges in practice.

description: We report thermal conductivity measurements of porous Vycor glass when it is empty and when the pores are filled with helium between 0.06 and 0.5 K. The filling of liquid 3He and liquid 4He inside the Vycor pores brings about respectively two and three fold reduction of the thermal conductivity as compared with empty Vycor. This dramatic reduction of thermal conductivity, not seen with solid 3He and 4He in the pores, is the consequence of hydrodynamic sound modes in liquid helium that greatly facilitate the quantum tunneling of the two-level systems (TLS) in Vycor and enhance the scattering of the thermal phonons in the silica network.

description: We report on the first detailed analysis of large three dimensional (3D) complex plasma structures in experiments performed in pure rf and combined rf+dc discharge modes. Inductively coupled plasma (ICP) is generated by an rf coil wrapped around the vertically positioned cylindrical glass tube at a pressure of 0.3 mbar. In addition, dc plasma can be generated by applying voltage to the electrodes at the ends of the tube far from the rf coil. The injected monodisperse particles are levitated in the plasma below the coil. A scanning laser sheet and a high resolution camera are used to determine the 3D positions of about $10^5$ particles. The observed bowl-shaped particle clouds reveal coexistence of various structures, including well-distinguished solid-like, less ordered liquid-like, and pronounced string-like phases. New criteria to identify string-like structures are proposed.

description: In the Republic of Moldova, agricultural policies aim to increase the compettveness of its farming sector, ensure the sustainable management of its natural resources and improve the living standards in rural areas. The state is an important player, allocatng fnancial resources for supportng agriculture and carrying out investment projects in this feld. A post-investment subsidy program incentvises agricultural producers to modernise their farms and producton. Farmers who have made investments in developing producton and post-harvest infrastructure could beneft from subsidies for these investments and fnancial resources allocated by the Agency for Interventon and Payments in Agriculture. However, it is not clear how benefcial these subsidies are for agricultural producers and whether the goals formulated by policies are met. A critcal challenge of policy assessment is the lack of regular surveys gathering farm-level data in Moldova. Another challenge is that the impact of some investments can only be quantfed with a delay of several years. This report results from an impact assessment study analysing the efectveness of existng policy measures. A survey of 800 farms was carried out to realise this assessment, which provided informaton about the actvity and investments made over several years. The team of researchers analysed the collected data to evaluate the policy measures covered by the survey. The study highlights essental facilitators and barriers to the farms' agricultural investment and business actvity. The impact assessment underlined that the investment subsidies had measurable positve efects on labour, farm producton and economic success. At the same tme, it indicated directons for improving and rebalancing policy instruments to increase the compettveness and sustainability of the agricultural sector of the Republic of Moldova.

description: The MSSM candidates arising from the heterotic MiniLandscape feature a very constrained supersymmetry breaking pattern. This includes a fully predictable gaugino mass pattern, which is compressed compared to the CMSSM, and an inverted sfermion hierarchy due to distinct geometric localisation, featuring stops as light as 1 TeV. The observed Higgs mass sets a lower bound m_{gluino} > 1.2 TeV on the gluino mass. The electroweak fine-tuning is reduced by a UV relation between the scalar mass of the two heavy families and the gluino mass. While large parts of the favoured parameter space escape detection at the LHC, the prospects to test the MiniLandscape models with future dark matter searches are very promising.

description: Gamma-ray bursts (GRBs) are among the most violent occurrences in the universe. They are powerful explosions, visible to high redshift, and thought to be the signature of black hole birth. They are highly luminous events and provide excellent probes of the distant universe. GRB research has greatly advanced over the past 10 years with the results from Swift, Fermi and an active follow-up community. In this review we survey the interplay between these recent observations and the theoretical models of the prompt GRB emission and the subsequent afterglows.

DECIPHERING THE AGGREGATION MECHANISMS IN HUMAN B2-MICROGLOBULIN
Creators: name: HALABELIAN, LEVON CHANT
Publisher: name: Universit� degli Studi di Milano
Year: 2014

description: Beta2-microglobulin (?2m) is a 99-residue globular protein that represents the light chain of the major histocompatibility complex class I (MHCI). ?2m is responsible for two types of human amyloid diseases: dialysis-related amyloidosis (DRA) caused by wt ?2m, and hereditary systemic amyloidosis due to the D76N ?2m mutant. Two independent projects were carried out during my PhD studies addressing both types of ?2m-related amyloidosis: (i) The human cells adopt a sophisticated unfolded protein response (UPR) system for targeting misfolded/aggregated polypeptides. However, the D76N variant, which is unstable and aggregation prone, bypasses the UPR system and reaches the extracellular space forming amyloids. To understand the mechanism(s) that allow the D76N variant to escape the UPR system and to characterize its effect on MHCI, we performed a complete structural and biophysical study on a MHCI bearing the D76N variant. Our results show that MHCI acts as a chaperone that stabilize and hide the amyloidogenic variant from the UPR system, and transfers it to cell membrane, where during its normal turnover, the D76N ?2m variant dissociates into blood serum and aggregates causing human pathologies. (ii) The early oligomeric species are responsible for cellular cytotoxicity in amyloidosis. Previous data showed a favourable association interface (between two facing D ?-strands) that may involve in ?2m oligomerization. To further elucidate its role in aggregation, we created a S-S linked dimer of ?2m (DimC33) that interacts via the DD interface. Our data show that DimC33 is highly amyloidogenic compared to wt ?2m, suggesting that dimerization through DD interface is instrumental for enhancing its aggregation propensity. Furthermore, DimC33 was co-crystallized in complex with Thioflavin-T (ThT), a well-known amyloid-specific dye, showing unique ThT binding site that may indicate a second key interface involved in ?2m oligomerization.
Two-neutron transfer probabilities and spatial-localization effects at the drip line

Subjects: subject: Nuclear Theory (nucl-th)

description: We examine Cr isotopes at the drip line, where surface effects related to the existence of a weakly bound $s1/2$ state are known to be important and tightly connected with the pairing phenomenon (anti-halo effect). For these weakly-bound isotopes, we evaluate the ground state to ground state two-neutron transfer probabilities within a mean-field-based approach. An important part of the discussion is devoted to the analysis of several procedures that can be employed to constrain the parameters of a phenomenological pairing interaction. The parameters are first adjusted to reproduce the experimental gaps evaluated with the five-point formula. This choice has however some consequences on the evolution of the pairing correlations along the isotopic chains and, in particular, at shell closures. Other procedures are then followed (adjustment on a theoretical pairing gap at mid-shell and on the two-neutron separation energies). For the transfer probabilities, we discuss the effects associated to different choices of the spatial localization of the pairing interaction. We indicate that the analysis of pair-transfer reactions for such cases (where the last bound state is a low-$l$ state in a weakly bound nucleus) may improve our understanding of two aspects: the spatial distribution of pairing correlations in nuclei and the general problem of the persistence of pairing at the drip lines.

description: The magneto-electrostatic tailoring of the supercurrent in quantum point contact ballistic Josephson junctions is demonstrated. An etched InAs-based heterostructure is laterally contacted to superconducting niobium leads and the existence of two etched side gates permits, in combination with the application of a perpendicular magnetic field, to modify continuously the magnetic interference pattern by depleting the weak link. For wider junctions the supercurrent presents a Fraunhofer-like interference pattern with periodicity h/2e whereas by shrinking electrostatically the weak link, the periodicity evolves continuously to a monotonic decay. These devices represent novel tunable structures that might lead to the study of the elusive Majorana fermions.

Transport of magnetic flux and the vertical structure of accretion discs: II. Vertical profile of the diffusion coefficients

description: We investigate the radial transport of magnetic flux in a thin accretion disc, the turbulence being modelled by effective diffusion coefficients (viscosity and resistivity). Both turbulent diffusion and advection by the accretion flow contribute to flux transport, and they are likely to act in opposition. We study the consequences of the vertical variation of the diffusion coefficients, due to a varying strength of the turbulence. For this purpose, we consider three different vertical profiles of these coefficients. The first one is aimed at mimicking the turbulent stress profile observed in numerical simulations of MHD turbulence in stratified discs. This enables us to confirm the robustness of the main result of Paper I obtained for uniform diffusion coefficients that, for weak magnetic fields, the contribution of the accretion flow to the transport velocity of magnetic flux is much larger than the transport velocity of mass. We then consider the presence of a dead zone around the equatorial plane, where the physical resistivity is high while the turbulent viscosity is low. We find that it amplifies the previous effect: weak magnetic fields can be advected orders of magnitude faster than mass, for dead zones with a large vertical extension. The ratio of advection to diffusion, determining the maximum inclination of the field at the surface of the disc, is however not much affected. Finally, we study the effect of a non-turbulent layer at the surface of the disc, which has been suggested as a way to reduce the diffusion of the magnetic flux. We find that the reduction of the diffusion requires the conducting layer to extend below the height at which the magnetic pressure equals the thermal pressure. As a consequence, if the absence of turbulence is caused by the large-scale magnetic field, the highly conducting layer is inefficient at reducing the diffusion.

description: The Kepler Mission is uniquely suited to study the frequencies of extrasolar planets. This goal requires knowledge of the incidence of false positives such as eclipsing binaries in the background of the targets, or physically bound to them, which can mimic the photometric signal of a transiting planet. We perform numerical simulations to predict the occurrence of astrophysical false positives detectable by the Mission, and quantify the fraction of them that would pass the Kepler candidate vetting procedure. By comparing their distribution with that of the Kepler Objects of Interest detected during the first six quarters of operation of the spacecraft, we infer the false positive rate of Kepler and study its dependence on spectral type, candidate planet size, and orbital period. We find that the global false positive rate of Kepler is 9.4 %, peaking for giant planets (6-22 Earth radii) at 17.7 %, reaching a low of 6.7 % for small Neptunes (2-4 Earth radii), and increasing again for Earth-size planets (0.8-1.25 Earth radii) to 12.3 %. Most importantly, we also quantify and characterize the distribution and rate of occurrence of planets down to Earth size with no prior assumptions on their frequency, by subtracting from the population of actual Kepler candidates our simulated population of astrophysical false positives. We find that 16.5 +/- 3.6 % of main-sequence FGK stars have at least one planet between 0.8 and 1.25 Earth radii with orbital periods up to 85 days. There is no significant dependence of the rates of planet occurrence between 0.8 and 4 Earth radii with spectral type. In the process, we derive also a prescription for the signal recovery rate of Kepler that enables a good match to both the KOI size and orbital period distribution, as well as their signal-to-noise distribution.

description: We explore the detection condition of a wide-separation planet through the perturbation induced by the planetary caustic for various microlensing parameters, especially for the size of the source stars. By constructing the fractional deviation maps at various positions in the space of microlensing parameters, we find that the pattern of the fractional deviation depends on the ratio of the source radius to the caustic size, and the ratio satisfying the observational threshold varies with the star-planet separation. We have also obtained the upper limits of the source size that allows the detection of the signature of the host star as a function of the separation for given observational threshold. It is shown that this relation further leads one to a simple analytic condition for the star-planet separation to detect the boundness of wide-separation planets as a function of the mass ratio and the source radius. For example, when 5% of the detection threshold is assumed, for a source star with the radius of ~1 R_sun, an Earth-mass planet and a Jupiter-mass planet can be recognized of its boundness when it is within the separation range of ~10 AU and ~30 AU, respectively. We also compare the separation ranges of detection by the planetary caustic with those by the central caustic. It is found that when the microlensing light curve caused by the planetary caustic happens to be analyzed, one may afford to support the boundness of the wide-separation planet farther than when that caused by the central caustic is analyzed. Finally, we conclude by briefly discussing the implication of our findings on the next-generation microlensing experiments.

description: Habitat complexity conferred by vegetation characteristics mediates key processes that govern the assemblage of insect communities. Thus, species within the community should only persist if their functional traits are well-matched to the conditions of their environment. Here, we compared ant assemblages between habitats in terms of species richness and functional-trait distribution at the species and the assemblage level. Ants were collected from 36 sites representing different degrees of habitat complexity mediated by standing vegetation. We found fewer ant species in simpler habitats, supporting the “habitat-heterogeneity” hypothesis. We measured key functional traits of ants that reflect their foraging and dispersal strategies, such as body size, femur length, antenna scape length, and head length / width. Interactions of species traits with measured habitat complexity variables were assessed at the species and the assemblage level using a fourth-corner approach. Ant traits were closely related to environmental complexity. In wooded habitats, ants were larger and had broader heads, while ants with longer antenna scapes prevailed in habitats with a dense herb / grass layer. Our study suggests that vegetation structural complexity can act as an environmental filter, driving ant assemblages in terms of both species numbers and functional traits. Our results can be used to predict turnover patterns in ant assemblages due to changes in management practices.
STABILIZATION OF BLOCH OSCILLATIONS OF ULTRACOLD ATOMS IN A RING CAVITY

description: The work presented in this thesis is dedicated to studies of stabilization of Bloch oscillations of ultracold atoms in a one-dimensional vertical optical lattice under the influence of the gravitational force. The atoms simultaneously interact with both the lattice potential and a unidirectionally pumped optical ring cavity whose vertical arm is collinear with the optical lattice. In the proposed scheme, the atoms not only exchange photons between the optical lattice laser beams, but also collectively scatter light from the pump into the reverse cavity mode. The initial investigation of the system without the cavity allows understanding of the importance of the perfectly adiabatic atomic motion in the observation of stable Bloch oscillations and how easily the adiabaticity can be broken due to a very fast switch-on of the lattice or its amplitude and phase modulation. Under certain parameter regimes, adding the ring cavity to the system provides a surprisingly positive feedback on the atomic dynamics. It is found that, while acting back on the atoms, the cavity field establishes a mode-locking mechanism which assists adiabatic rapid passages between adjacent momentum states. Thus, the cavity-induced feedback mechanism enforces the adiabaticity of the process and reveals a regime where the Bloch oscillations are self-synchronized for long times. This stabilization technique is shown to steer the atoms to the lowest Bloch band preventing the problem of interband tunneling. A demonstration is also made of the ability of the system to stabilize the atomic Bloch oscillations against technical amplitude or phase noise and even suppress dephasing due to the atom-atom interactions. Furthermore, the response of the system to the atomic motion is generated in the form of perfectly detectable periodic bursts of light emitted into the counter-propagating cavity mode. Thus, the system offers a continuous and reliable non-destructive method to monitor the Bloch oscillations dynamics without perturbing their periodicity by detecting the scattered light transmitted through the cavity. All features studied in this work may be crucial for future improvements of the design of atomic gravimeters based on recording Bloch oscillations.

description: Carbon monoxide (CO) is the most commonly used tracer of molecular gas in the inner regions of protoplanetary disks. CO can be used to constrain the excitation and structure of the circumstellar environment. Absorption line spectroscopy provides an accurate assessment of a single line-of-sight through the protoplanetary disk system, giving more straightforward estimates of column densities and temperatures than CO and molecular hydrogen emission line studies. We analyze new observations of ultraviolet CO absorption from the Hubble Space Telescope along the sightlines to six classical T Tauri stars. Gas velocities consistent with the stellar velocities, combined with the moderate-to-high disk inclinations, argue against the absorbing CO gas originating in a fast-moving disk wind. We conclude that the far-ultraviolet observations provide a direct measure of the disk atmosphere or possibly a slow disk wind. The CO absorption lines are reproduced by model spectra with column densities in the range N(^{12}CO) ~ 10^{16} - 10^{18} cm^{-2} and N(^{13}CO) ~ 10^{15} - 10^{17} cm^{-2}, rotational temperatures T_{rot}(CO) ~ 300 - 700 K, and Doppler b-values, b ~ 0.5 - 1.5 km s^{-1}. We use these results to constrain the line-of-sight density of the warm molecular gas (n_{CO} ~ 70 - 4000 cm^{-3}) and put these observations in context with protoplanetary disk models.

description: The UMass Amherst Libraries will host “Natural History Prints” an exhibit of photographs by John Green, through May 3, 2009, at the Integrated Sciences and Engineering Library, Lederle Lowrise, UMass Amherst.

The exhibit consists of 14 photographic prints, taken with a film camera using natural light. Most of the subjects were shot locally and represent the four seasons.

Inspired by the simple and abundant beauty of the natural world, John Green has been photographing nature for over thirty years. Trained as an interpretive naturalist, he is skilled in bird and plant identification, and an expert in “birding by ear.” Green has run a weeklong field school on nature photography for the Massachusetts Audubon Society for more than 15 years and leads photographic excursions all over the country.

Green has been featured on the television series PBS Kids and his prints have been exhibited widely throughout Massachusetts. His slide shows have been presented from Maine to Florida.

Green has lived in Western Massachusetts since 1972 where he frequently is found photographing the wilds of Quabbin Reservoir. “Natural light is my tool. Patience, diligence, and intimate knowledge of my subject matter are the keys to capturing nature on film,” says Green. “Often I photograph a subject over several years before I am satisfied.”

description: We report electrical conductance measurements of Bi nanocontacts created by repeated tip-surface indentation using a scanning tunneling microscope at temperatures of 4 K and 300 K. As a function of the elongation of the nanocontact we measure robust, tens of nanometers long plateaus of conductance G0 = 2e^2/h at room temperature. This observation can be accounted for by the mechanical exfoliation of a Bi(111) bilayer, a predicted QSH insulator, in the retracing process following a tip-surface contact. The formation of the bilayer is further supported by the additional observation of conductance steps below G0 before break-up at both temperatures. Our finding provides the first experimental evidence of the possibility of mechanical exfoliation of Bi bilayers, of the existence of the QSH phase in a two-dimensional crystal, and, most importantly, of the observation of the QSH phase at room temperature.

description: In this study, we explored the potential of a newly prepared nano-zero valent zinc (nZVZn), biochar (BC)/nZVZn and BC/hydroxyapatite-alginate (BC/HA-alginate) composites for the removal of inorganic As species from water. Relatively, higher percentage removal of As(III) and As(V) was obtained by nZVZn at pH 3.4 (96% and 94%, respectively) compared to BC/nZVZn (90% and 88%) and BC/HA-alginate (88% and 80%) at pH 7.2. Freundlich model provided the best fit (R2 = up to 0.98) for As(III) and As(V) sorption data of all the sorbents, notably for nZVZn. The pseudo-second order model well-described kinetics of As(III) and As(V) (R2 = 0.99) sorption on all the sorbents. The desorption experiments demonstrated that the As removal efficiency, up to the third sorption/desorption cycle, was in the order of nZVZn ∼ BC/HA-alginate (88%) > BC/nZVZn (84%). The Fourier transform infrared spectroscopy depicted that the –OH, –COOH, Zn–O and Zn–OH surface functional groups were responsible for the sorption of As(III) or As(V) on the sorbents investigated here. This study highlights that removal of As species from water by BC/nZVZn composite can be compared with nZVZn, suggesting that integrating BC with nZVZn could efficiently remove As from As-contaminated drinking water. This is the first study to explore the potential of a newly prepared sugarcane bagasse biochar/nano-zerovalent zinc (BC/nZVZn) based composite for the removal of inorganic arsenic (As) species from water. The results indicated high percentage removal of As(III) and As(V) from water by BC/nZVZn that were comparable to nZVZn alone.

description: We present Warm Spitzer/IRAC secondary eclipse time series photometry of three short-period transiting exoplanets, HAT-P-3b, HAT-P-4b and HAT-P-12b, in both the available 3.6 and 4.5 micron bands. HAT-P-3b and HAT-P-4b are Jupiter-mass, objects orbiting an early K and an early G dwarf stars, respectively. For HAT-P-3b we find eclipse depths of 0.112%+0.015%-0.030% (3.6 micron) and 0.094%+0.016%-0.009% (4.5 micron). The HAT-P-4b values are 0.142%+0.014%-0.016% (3.6 micron) and 0.122%+0.012%-0.014% (4.5micron). The two planets' photometry is consistent with inefficient heat redistribution from their day to night sides (and low albedos), but it is inconclusive about possible temperature inversions in their atmospheres. HAT-P-12b is a Saturn-mass planet and is one of the coolest planets ever observed during secondary eclipse, along with hot Neptune GJ 436b and hot Saturn WASP-29b. We are able to place 3$σ$ upper limits on the secondary eclipse depth of HAT-P-12b in both wavelengths: < 0.042% (3.6 micron) and <0.085% (4.5 micron). We discuss these results in the context of the {\it Spitzer} secondary eclipse measurements of GJ 436b and WASP-29b. It is possible that we do not detect the eclipses of HAT-P-12b due to high eccentricity, but find that weak planetary emission in these wavelengths is a more likely explanation. We place 3 sigma upper limits on the |e cos(omega)| quantity (where e is eccentricity and omega is the argument of periapsis) for HAT-P-3b (<0.0081) and HAT-P-4b (<0.0042), based on the secondary eclipse timings.
