description: The molecular evolution that occurs in collapsing prestellar cores is investigated. To model the dynamics, we adopt the Larson-Penston (L-P) solution and analogues with slower rates of collapse. For the chemistry, we utilize the new standard model (NSM) with the addition of deuterium fractionation and grain-surface reactions treated via the modified rate approach. The use of surface reactions distinguishes the present work from our previous model. We find that these reactions efficiently produce H2O, H2CO, CH3OH, N2, and NH3 ices. In addition, the surface chemistry influences the gas-phase abundances in a variety of ways. The current reaction network along with the L-P solution allows us to reproduce satisfactorily most of the molecular column densities and their radial distributions observed in L1544. The agreement tends to worsen with models that include strongly delayed collapse rates. Inferred radial distributions in terms of fractional abundances are somewhat harder to reproduce. In addition to our standard chemical model, we have also run a model with the UMIST gas-phase chemical network. The abundances of gas-phase S-bearing molecules such as CS and CCS are significantly affected by uncertainties in the gas-phase chemical network. In all of our models, the column density of N2H+ monotonically increases as the central density of the core increases during collapse from 3 10^4 cm-3 to 3 10^7 cm-3. Thus, the abundance of this ion can be a probe of evolutionary stage. Molecular D/H ratios in assorted cores are best reproduced in the L-P picture with the conventional rate coefficients for fractionation reactions. If we adopt the newly measured and calculated rate coefficients, the D/H ratios, especially N2D+/N2H+, become significantly lower than the observed values.

translational recoding

description: Programmed -1 ribosomal frameshifting (-1 PRF) is a translational recoding mechanism in which cis-acting elements direct elongating ribosomes to slip in the 5’ direction on mRNAs by one base. -1 PRF activity is able to downregulate gene expression by directing elongating ribosomes to premature termination codons, activating the nonsense-mediated decay pathway (NMD) and mRNA degradation. Computational methods developed by our lab identified a -1 PRF signal within the Janus Kinase 2 (JAK2) mRNA, which encodes a tyrosine kinase involved in cell proliferation, survival, and apoptosis. Here, we characterize the JAK2 -1 PRF signal. In addition, we show that the JAK2-V617F mutation, closely linked to myeloproliferative neoplasms (MPN), decreases JAK2 mediated frameshifting. This may contribute to the observed increase of JAK2 mRNA levels in MPN patient microarray and RNAseq data. Because it has been established that elevated expression levels of JAK proteins are sufficient to transform cells in vitro, our findings suggest that this may contribute to the observed increase in JAK2 kinase activity in mutant cells and thus the transforming activity of the V617F mutation. Our study offers a possible translational-level mechanism behind the development of MPNs, opening the door to new therapies for MPN patients.

description: Dynamics of relativistic outflows along the rotation axis of a Kerr black hole is investigated using a simple model that takes into account the relativistic tidal force of the central source as well as the Lorentz force due to the large-scale electromagnetic field which is assumed to be present in the ambient medium. The evolution of the speed of the flow relative to the ambient medium is studied. In the force-free case, the resulting equation of motion predicts rapid deceleration of the initial flow and an asymptotic relative speed with a Lorentz factor of 2^1/2. In the presence of the Lorentz force, the long-term relative speed of the clump tends to the ambient electrical drift speed.

description: We present a multi-wavelength analysis of the galaxies in nine clusters selected from the WINGS dataset, examining how galaxy structure varies as a function of wavelength and environment using the state of the art software GALAPAGOSII. We simultaneously fit single Sérsic functions on three optical (u, B and V) and two near-infrared (J and K) bands thus creating a wavelength-dependent model of each galaxy. We measure the magnitudes, effective radius ($R_{e}$) the Sérsic index ($n$), axis ratio and position angle in each band. The sample contains 790 cluster members (located close to the cluster center < 0.64 R$_{200}$ and 254 non-member galaxies that we further separate based on their morphology into ellipticals, lenticulars and spirals. We find that the Sérsic index of all galaxies inside clusters remains nearly constant with wavelength while $R_{e}$ decreases as wavelength increases for all morphological types. We do not observe a significant variation on n and $R_{e}$ as a function of projected local density and distance from the clusters center. Comparing the n and $R_{e}$ of bright cluster galaxies with a subsample of non-member galaxies we find that bright cluster galaxies are more concentrated (display high $n$ values) and are more compact (low $R_{e}$). Moreover, the light profile ($\mathcal{N}$) and size ($\mathcal{R}$) of bright cluster galaxies does not change as a function of wavelength in the same manner as non-member galaxies.

description: We provide a statistically robust and accurate framework to measure and track the polarisation state of light employing Hong-Ou-Mandel interference. This is achieved by combining the concepts of maximum likelihood estimation and Fisher information applied to photon detection events. Such an approach ensures that the Cramér-Rao bound is saturated and changes to the polarisation state are established in an optimal manner. Using this method, we show that changes in the linear polarisation state can be measured with 0.6 arcminute precision (0.01 degrees).

description: We study the back reaction effect of massless minimally coupled scalar field at finite temperatures in the background of Einstein universe. Substituting for the vacuum expectation value of the components of the energy-momentum tensor on the RHS of the Einstein equation, we deduce a relationship between the radius of the universe and its temperature. This relationship exhibit a maximum temperature, below the Planck scale, at which the system changes its behaviour drastically. The results are compared with the case of a conformally coupled field. An investigation into the values of the cosmological constant exhibit a remarkable difference between the conformally coupled case and the minimally coupled one.

Bystanders' Perceptions of Police-Civilian Conflict

description: Nearly every human being automatically notices and remembers the race of each individual they encounter (Cosmides et al., 2003). Not only is race something that humans are often very attentive to, but it is also something that can affect perceptions of conflict, particularly between police and civilians (Weitzer & Tuch, 1999). Yet, very little research has been done specifically on bystanders’ perceptions of nonviolent conflicts with regard to race. The current study intended to partially fill the gap in the current literature by exploring bystanders’ perceptions of police-civilian nonviolent conflict. Specifically, how does the race of the police officer and race of the civilian impact bystanders’ perceptions of the conflict? In this study, race of the police officer and civilian were manipulated by giving participants slightly different variations of vignettes. The storyline of the vignettes was the same; the only difference between vignettes were the races (Black, White or race not mentioned) of the parties involved. We hypothesized that both changing the race of the police officer and changing the race of the civilian involved in the conflict would affect bystanders’ perceptions of the conflict; however, it is unclear how bystanders’ perceptions may change, based on some discrepancies in current literature (Orbe & Warren, 2000; Weitzer, 1999). We found that participants tended to rate conflicts involving a Black police officer as being more the civilian’s fault, as compared to when the police officer was either White or of unmentioned race, which provides important novel information as to how race can affect perceptions of conflict.

description: Product sampling is a widely used strategy to introduce consumers to unusual products in an effort to build market penetration and demand. Two products that are especially popular in the mid-south of the U.S. include pawpaw fruits and sorghum syrup. This study examines regional differences of consumer interest sampling products made from pawpaws and sorghum syrup in farmers markets while considering possible spatial and demographic characteristics influencing consumer interest. The results showed stronger state-by-state differences for sorghum products than for pawpaw products with particularly higher likelihood to sample products in the deep southern states.

description: In 2011, nearly 1.7 million Georgians, 17.9% of the population, lived in poverty, and of those, 24.8% were children. Poverty is closely associated with food insecurity. Food insecurity has been associated with various developmental consequences for U.S. children. Research indicates that hungry children do more poorly in school and have lower academic achievement because they are not well prepared for school and cannot concentrate. This research examines the relationship between food insecurity, the National School Lunch Program (NSLP) and academic achievement of 5th grade students in Georgia.

description: The use of in-situ burning (ISB) as a clean-up response in the event of an oil spill has generated controversy because of unburned hydrocarbons and products of incomplete combustion left behind on an ISB site. These substances threaten marine life, both in the ocean and on the ocean floor. Treating crude oil as a multicomponent liquid fuel, this manuscript investigates the effect of carbon-based nanomaterials, acetylene black (AB) and multi-walled carbon nanotube (MWNT), on the combustion and flame characteristics of crude sourced from the Bakken formation (ND, USA). Sub-millimeter droplets of colloidal suspensions of Bakken crude and nanomaterials at various particle loadings were burned, and the process was captured with CMOS and CCD cameras. The resulting images were post-processed to generate burning rate, ignition delay, total combustion time, and flame stand-off (FSR) ratio data for the various crude suspensions. A maximum combustion rate enhancement of 39.5% and 31.1% was observed at a particle loading of 0.5% w/w acetylene black nanoparticles and 0.5% w/w multi-walled carbon nanotubes, respectively. Generally, FSR for pure Bakken was noted as larger than for Bakken with nanoparticle additives. These results are expected to spur further investigations into the use of nanomaterials for ISB crude oil clean-ups.

When the solitons are scattered from symmetrical configurations the scattering angles observed agree with the earlier π/N predictions based on the model on R_2 with standard boundary conditions. When the boundary conditions are not symmetric the angles are different from π/N. We present an explanation of our observed patterns based on a properly formulated geodesic approximation.

The Factors Important to Catalysis by Serine Proteases:  Structure of Diisopropylfluorophosphate-Inhibited Bovine Trypsinogen Refined at 2.1 Å Resolution
Creators: name: Jones, Melvin O.
Publisher: name: California Institute of Technology
Year: 1982
Subjects: Chemistry

description: Crystals of bovine trypsinogen inhibited with diisopropylfluorophosphate (DFP) were grown at pH 7 and x-ray intensity data to 2.1 Å resolution were collected.  The reflections were assigned the phases determined by Kossiakoff (1977) for the isomorphous native trypsinogen structure. Using difference fourier techniques, the resulting protein structure was refined to a residual of 18.2%. As expected, a comparison between (DIP)-trypsinogen and the native trypsinogen structures shows all the structural differences to be in the catalytic site region. However, the structure of the catalytic region was expected to be quite similar to that of DFP-inhibited bovine trypsin at neutral pH, but there exist some marked differences.

In trypsin, one of the isopropyl groups of the inhibitor is analogous to the leaving group of a specific substrate and is hydrolyzed off the inhibitor. In the resulting monoisopropylphosphoryl (MIP)-trypsin, the inhibitor is oriented with a non-esterified phosphoryl oxygen in the oxyanion stabilization site as expected for a tetrahedral intermediate in proteolysis. His 57 Nε2 points toward the phosphoryl oxygen at the leaving group site, and is in a position suitable for proton donation to the leaving group.

By contrast, the inhibitor on DIP-trypsinogen remains intact and the presence of electron density at each of the three possible isopropyl locations indicates that the groups of the inhibitor are less specifically oriented. After independent refinement of each of the three possible orientations, the favored orientation was with isopropyl groups near the oxyanion and leaving group sites and the non-esterified phopsphoryl oxygen hydrogen-bonded through two solvent molecules to Ser 214 O. The imidazole ring of His 57 is displaced from its native position at the catalytic site out into the solvent region where it forms hydrogen-bonds to Tyr 94 0 and through a solvent molecule to Ser 214 O. Ser 195 Oγ has moved closer to the position occupied by the His 57 imidazole in native trypsinogen and MIP-trypsin.

Both statistical variation in orientation of the inhibitor and movement of Ser 195 Oγ toward the native imidazole site can be explained by the nonfunctionality of the oxyanion binding site in trypsinogen.

The difference between DIP-Tgen and MIP-trypsin thus suggests both non-productive transition state or substrate binding and stereochemical incompatability between the tetrahedral intermediate and the native imidazole site as possible contributors to the relative inactivity of the proenzyme.

Conversely, and of more general importance, these results emphasize the importance of exact stereochemical alignment in generating a functional catalytic enzyme.

description: Generation of magnetic fields during inflation is a promising mechanism for the origin of the observed large scale magnetic fields in the universe. Among several attempts, a popular model is one where the inflaton and the electromagnetic field are coupled through a coupling function $f$ leading to a term in the Lagrangian density of the form, $f^2 F^{μν} F_{μν}$. A number of potential difficulties with such models have been raised in the literature. In our earlier work, we have suggested viable models of inflationary magnetogenesis which avoid these problems and at the same time can lead to either nonhelical or helical magnetic fields of astrophysical interest. Our models require a low energy scale for inflation and reheating (reheating temperature, $T_R < 10^4$ GeV) and generate a blue spectrum of electromagnetic (EM) field which peaks around the horizon scale of reheating. We show here that the anisotropic stress associated with these EM fields naturally source the production of a stochastic background of Gravitational waves (GW) with frequencies in the range of tens of nano Hertz to milli Hertz. These two extremes of the range can be probed respectively by pulsar timing arrays (PTA) experiments and the upcoming Laser Interferometric Space Array (LISA). The peak value of the GW spectrum energy represented by $d Ω_{GW}/d \ln k$ is $ 10^{-6} $ for the models which lead to nonhelical primordial fields and $2 \times 10^{-6} $ for the helical case for $T_R=100$ GeV. In this case the spectrum peaks at a frequency $30 μ$Hz for non helical case and at $40 μ$Hz for helical case. These values are obtained when the ratio of EM energy density to the cosmological density at reheating $ε\sim 1$ and decrease approximately as $ε^2$ for smaller values.

We find that the utilization rate of agricultural land and level of agricultural labor output in the plain areas are higher than in the hilly areas; at the same time, the degree of mechanization of agricultural land utilization and farmers' land use scale are larger in the plain areas. But the crop type in the plain areas is single, and the decline rate of the growing area of food crops is higher in recent twenty years; meanwhile, the material input costs and opportunity cost of labor for the agricultural land utilization in the plain areas are greater than in the hilly areas.

description: We describe a multi-order spectrograph concept suitable for 8m-class telescopes, using the intrinsic spectral resolution of Superconducting Tunneling Junction detectors to sort the spectral orders. The spectrograph works at low orders, 1-5 or 1-6, and provides spectral coverage with a resolving power of R~8000 from the atmospheric cutoff at 320 nm to the long wavelength end of the infrared H or K band at 1800 nm or 2400 nm. We calculate that the spectrograph would provide substantial throughput and wavelength coverage, together with high time resolution and sufficient dynamic range. The concept uses currently available technology, or technologies with short development horizons, restricting the spatial sampling to two linear arrays; however an upgrade path to provide more spatial sampling is identified. All of the other challenging aspects of the concept - the cryogenics, thermal baffling and magnetic field biasing - are identified as being feasible.

The results show that,① as the bare karst areas are lack of water and soil and highly prone to droughts and floods, land utilization in such areas should follow the principle of soil and water conservation and ecological restoration, emphasize both the ecological benefit and the economic benefit and reasonably configure the land resources to achieve the virtuous circle;②in covered karst areas, the most important task is to take measures to prevent the appearance of secondary kast rock desertification, water exhaustion and karst collapse;③ the buried karst areas shall mainly focus on prevention of overlaying sand shale collapse, and possible pollution of deep karst water and the surface land resulted from exploration and exploitation of oil and gas and geothermal water.④ The final conclusion is that features and problems of land utilization of the three karst types are different from each other, and that the general principle for land use in karst regions shall be based on the local conditions.

description: A deep-learning-based surrogate model is developed and applied for predicting dynamic subsurface flow in channelized geological models. The surrogate model is based on deep convolutional and recurrent neural network architectures, specifically a residual U-Net and a convolutional long short term memory recurrent network. Training samples entail global pressure and saturation maps, at a series of time steps, generated by simulating oil-water flow in many (1500 in our case) realizations of a 2D channelized system. After training, the `recurrent R-U-Net' surrogate model is shown to be capable of accurately predicting dynamic pressure and saturation maps and well rates (e.g., time-varying oil and water rates at production wells) for new geological realizations. Assessments demonstrating high surrogate-model accuracy are presented for an individual geological realization and for an ensemble of 500 test geomodels. The surrogate model is then used for the challenging problem of data assimilation (history matching) in a channelized system. For this study, posterior reservoir models are generated using the randomized maximum likelihood method, with the permeability field represented using the recently developed CNN-PCA parameterization. The flow responses required during the data assimilation procedure are provided by the recurrent R-U-Net. The overall approach is shown to lead to substantial reduction in prediction uncertainty. High-fidelity numerical simulation results for the posterior geomodels (generated by the surrogate-based data assimilation procedure) are shown to be in essential agreement with the recurrent R-U-Net predictions. The accuracy and dramatic speedup provided by the surrogate model suggest that it may eventually enable the application of more formal posterior sampling methods in realistic problems.

description: An axisymmetric model for the Crab Nebula is constructed to examine the flow dynamics in the nebula. The model is based on that of Kennel and Coroniti (1984), although we assume that the kinetic-energy-dominant wind is confined in an equatorial region. The evolution of the distribution function of the electron-positron plasma flowing out in the nebula is calculated. Given viewing angles, we reproduce an image of the nebula and compare it with Chandra observation. The reproduced image is not a ring-like but rather 'lip-shaped'. It is found that the assumption of toroidal field does not reproduce the Chandra image. We must assume that there is disordered magnetic field with an amplitude as large as the mean toroidal field. In addition, the brightness contrast between the front and back sides of the ring cannot be reproduced if we assume that the magnetization parameter $σ$ is as small as $\sim 10^{-3}$. The brightness profile along the semi-major axis of the torus is also examined. The non-dissipative, ideal-MHD approximation in the nebula appears to break down. We speculate that if the magnetic energy is released by some process that produce turbulent field in the nebula flow and causes heating and acceleration, e.g. by magnetic reconnection, then the present difficulties may be resolved (i.e. we can reproduce a ring image, and a higher brightness contrast). Thus, the magnetization parameter $σ$ can be larger than previously expected.

description: Agricultural pollution has become the dominant source of water pollution in China and the carbon reduction in agricultural aspect is pressing. Based on list analysis method, the COD, TN and TP in agriculture in 28 provinces in China from 1995 to 2010 were evaluated and compared. By dint of directional distance function, the economics mechanism to reduce carbon emission was discussed. The reduction efficiency and potential of three kinds of pollutants were estimated. The regression indicates that the educational degree, income level and work play a crucial role in carbon emission.

description: We investigate the dynamics of a bulk scalar field with various decay channels in the Randall-Sundrum infinite braneworld scenario. A bulk scalar field in this scenario has a quasi-localized mode which dominates the late-time behavior near the brane. As for this mode, an interesting point is the presence of dissipation caused by the escape of the energy in the direction away from the brane, even if the bulk scalar field does not have the interaction with the other bulk fields in the bulk and fields on the brane. We can interpret that this lost energy is transfered to the dark radiation. We show that such an effective 4-dimensional description for a bulk scalar field is valid including the various processes of energy dissipation.

description: To analyze the efficiency of the agro-ecosystem of Dongting Rim in Hunan Province, this paper adopted the emergy theory to study the agricultural output of this region during 2001 to 2010. The results showed that the value of regional agricultural emergy output increased by 44.68% to (6.50 E) sej, but lower than the growth of non-agricultural industry output. Compared with 2001, the emergy output of planting industry was (4.10E) sej in 2010 which occupied 63.09% of the total agricultural emergy output and got an increase of 2.93 percentage points, while the emergy output of stock farming got a decrease of 2.87 percentage points. The growth of fishery emergy output was not in conformity with the characteristics of Dongting Rim in Hunan. From the contrast between emergy output and economic output, we could find that the economic return ratio of planting industry and fishery industry were lower than those of forestry industry and stock farming industry, which indicated that it is necessary to improve the economic benefits of planting industry and fishery industry which were the traditional industries with advantages of the Dongting Rim in Hunan.

description: We prove two estimates of the rate of convergence in the Lindeberg theorem, involving algebraic truncated third-order moments and the classical Lindeberg fraction, which generalize a series of inequalities due to (Esseen, 1969), (Rozovskii, 1974), (Wang, Ahmad, 2016), some of our recent results in (Gabdullin, Makarenko, Shevtsova, 2018, 2019) and, up to constant factors, also (Katz, 1963), (Petrov, 1965), (Osipov, 1966). The technique used in the proof is completely different from that in (Wang, Ahmad, 2016) and is based on some extremal properties of introduced fractions which has not been noted in (Katz, 1963), (Petrov, 1965), (Wang, Ahmad, 2016).

description: Culicoides (Avaritia) pusilloides Wirth and Blanton
 Culicoides pusilloides Wirth and Blanton, 1955: 104 (Panama).
 Culicoides (Avaritia) pusilloides: Wirth 1974: 21 (in New World Catalog south of the USA; distribution); Borkent and Spinelli 2000: 28 (in New World catalog south of USA; distribution); Borkent and Spinelli 2007: 63 (in Neotropical Catalog; distribution).
 Discussion. This species is widely distributed in the Neotropics and was previously known from Guatemala and Belize to Panama (Borkent and Spinelli 2000, 2007). Two other very similar species in the subgenus Avaritia Fox also occur in Mexico, C. pusillus Lutz and C. boydi Wirth and Mullens. Culicoides pusilloides differs from C. boydi by the 2 nd radial cell that is distinctly pale on its apical half, a shorter proboscis (Proboscis/Head ratio 0.50) and the short, broad aedeagus with sides strongly bowed outward. We provide the first records of C. pusilloides from Mexico.

description: We measure the mode-resolved direction of the precessional motion of the magnetic order, i.e., magnon polarization, via the chiral term of inelastic polarized neutron scattering spectra. The magnon polarisation is important in spintronics, affecting thermodynamic properties such as the magnitude and sign of the spin Seebeck effect. The observation of both signs of magnon polarization in Y3Fe5O12 also gives direct proof of its ferrimagnetic nature. The experiments agree very well with atomistic simulations of the scattering cross section.

description: In the hierarchical structure formation model, galaxies grow through various merging events. Numerical simulations indicate that the mergers can enhance the activity of the central supermassive black holes in the galaxies. Pfeifle et al. (2019a) identified a system of three interacting galaxies, J0849$+$1114, and provided multiwavelength evidence of all three galaxies containing active galactic nuclei. The system has substantial radio emission, and with high-resolution radio interferometric observation we aimed to investigate its origin, whether it is related to star formation or to one or more of the active galactic nuclei in the system. We performed high-resolution continuum observation of J0849$+$1114 with the European Very Long Baseline Interferometry Network at $1.7$ GHz. We detected one compact radio emitting source at the position of the easternmost nucleus. Its high brightness temperature and radio power indicate that the radio emission originates from a radio-emitting active galactic nucleus. Additionally, we found that significant amount of flux density is contained in $\sim 100$ milliarcsec-scale feature related to the active nucleus.
