Considerations on rescattering effects for threshold photo- and electro-production of $π^0$ on deuteron

description: We show that for the S-state $π^0$-production in processes $γ+d\to d+π^0$ and $e^-+d\to e^-+d+π^0$ the rescattering effects due to the transition: $ γ+d\to p+p+π^-$ (or $n+n+π^+)\to d+π^0$ are cancelled out due to the Pauli principle. The large values for these effects predicted in the past may result from the fact that the spin structure of the corresponding matrix element and the necessary antisymmetrization induced by the presence of identical protons (or neutrons) in the intermediate state was not taken into account accurately. One of the important consequences of these considerations is that $π^0$ photo- and electro-production on deuteron near threshold can bring direct information about elementary neutron amplitudes.

description: We present two-dimensional plasmonic Doppler grating (PDG) for broadband azimuthal angle-resolved nanophotonic applications. The PDG consists of a set of non-concentric circular rings mimicking the wavefronts of a moving point source that exhibits Doppler Effect and thereby offers continuous azimuthal angle-dependent lattice momentum for photon-plasmon coupling. The center and span of the working frequency window are fully designable for optimal performance in specific applications. We detail the design, fabrication and optical characterization of the PDG. The design of Doppler grating provides a general platform for in-plane angle-resolved nanophotonic applications.

description: We analyze the structure of meson loop corrections to the O($m_s$) expressions for the baryon masses and magnetic moments in heavy-baryon chiral perturbation theory (HBChPT), and show in detail how the bulk of the corrections are absorbed into redefinitions of the unknown parameters of the O($m_s$) chiral expansion. To effect this analysis, we use the three-flavor-index representation of the effective baryon fields and HBChPT developed in a preceding paper, and a decomposition of the corrections in terms of effective one-, two-, and three-quark operators. The results show why the loop corrections have so little effect on fits to the masses and moments, and do not seriously disrupt the Gell-Mann--Okubo relations for the masses and the Okubo relation for the moments even though individual loops can be quite large. We also examine the momentum structure of the residual loop corrections, and comment on limits on their validity in HBChPT. The structural analysis can be generalized straightforwardly to other problems in HBChPT using the three-flavor-index representation of the effective baryon fields, and provides a fairly simple way to determine what parts of the loop corrections are actually significant in a given setting.

description: Anaerobic digestion allows farmers to create renewable energy and significantly reduce manure methane emissions. Methane emission reductions have the potential to be an important source of carbon dioxide offsets under cap and trade climate legislation. Estimates of the aggregate supply curve for CO2e offsets were developed based upon dairy farm data collected by the USDA/ERS Agricultural Resource and Management Survey (ARMS). The results provide insight regarding the potential for methane emission reductions and renewable energy generation on U.S. dairy farms. Offset prices in excess of $15 per ton of carbon dioxide equivalent would be required to reduce methane emissions from manure storages by 50 percent from 2005 levels.

description: We propose a bosonic $U(1)$ rotor model on a three dimensional space-time lattice. With the inclusion of a Maxwell term, we show that the low-energy semi-classical behavior of our model is consistent with the Chern-Simons field theory, $S= \int \text{d}^3 x\ \frac{K_{IJ}}{4π} A_I \text{d} A_J$ at low energies. We require that the action be periodic in the lattice variables, which enforces the quantization of the $K$-matrix as a symmetric integer matrix with even diagonals. We also show that our lattice model has the exact $1$-symmetries. In particular, some of those 1-symmetries are anomalous (i.e. non-on-site) in the expected way. The anomaly can be probed via the breaking of those $1$-symmetries by the boundaries of space-time.

B Production Asymmetries in Perturbative QCD

description: This paper explores a new mechanism for B production in which a b quark combines with a light parton from the hard-scattering process before hadronizing into the B hadron. This recombination mechanism can be calculated within perturbative QCD up to a few nonperturbative constants. Though suppressed at large transverse momentum by a factor Lambda_QCD m_b/p_t^2 relative to b quark fragmentation production, it can be important at large rapidities. A signature for this heavy-quark recombination mechanism in proton-antiproton colliders is the presence of rapidity asymmetries in B cross sections. Given reasonable assumptions about the size of nonperturbative parameters entering the calculation, we find that the asymmetries are only significant for rapidities larger than those currently probed by collider experiments.

description: Over the last decades traditional energy sources are increasingly replaced by energy from biomass and this trend is expected to continue into the future. Assessing the efficiency of bioenergy policies requires a comprehensive analysis of the interrelationship between agricultural and energy markets. This study analyzes the impacts of two alternative EU greenhouse gas emission mitigation scenarios on the utilization of biomass for energy production and the price of agricultural products. To this end, we combine the energy system model TIMES PanEU and the agricultural sector model ESIM. We establish a consistent interface between the models and run them in an iterative procedure where TIMES PanEU represents the demand side for energy crops and ESIM their supply side. According to our results, an extension of the mandatory reduction of emissions has strong biomass demand effects and affects the agricultural sector in its entirety. Due to the increased demand for energy crops, average crop prices in the EU increase by an estimated 30 percentage points in 2050. The expanded area use for production of energy crops inside the EU27 turns the EU from being a net exporter to a net importer for many important agricultural commodities.
Parametric study of polar configurations around binaries

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Dynamical studies suggest that most of the circumbinary discs (CBDs) should be coplanar. However, under certain initial conditions, the CBD can evolve toward polar orientation. Here we extend the parametric study of polar configurations around detached close-in binaries through $N$-body simulations. For polar configurations around binaries with mass ratios $q$ below $0.7$, the nominal location of the mean motion resonance (MMR) $1~:~4$ predicts the limit of stability for $e_{B} > 0.1$. Alternatively, for $e_{B} < 0.1$ or $q \sim 1$, the nominal location of the MMR $1~:~3$ is the closest stable region. The presence of a} giant planet increases the region of forbidden polar configurations around low mass ratio binaries with eccentricities $e_B\sim0.4$ with respect to rocky earth-like planets. For equal mass stars, the eccentricity excitation $Δe$ of polar orbits smoothly increases with decreasing distance to the binary. For $q<1$, $Δe$ can reach values as high as $0.4$. Finally, we studied polar configurations around $HD~98800BaBb$ and show that the region of stability is strongly affected by the relative positions of the nodes. The most stable configurations in the system correspond to polar particles, which are not expected to survive on longer time-scales due to the presence of the external perturber HD~$98800AaAb$.

description: Three different M31 disk fields, spanning a range of stellar populations, were observed by Chandra. We report the X-ray point source luminosity function (LF) of each region, and the LF of M31's globular clusters, and compare these with each other and with the LF of the galaxy's bulge. To interpret the results we also consider tracers of the stellar population, such as OB associations and supernova remnants. We find differences in the LFs among the fields, but cannot definitively relate them to the stellar content of the fields. We find that stellar population information, average and maximum source luminosities, X-ray source densities, and slopes of the LF are useful in combination.

Studies of singlet exciton fission in perylenediimide films and triplet exciton transfer at organic:inorganic interfaces

description: Herein, I showcase three studies that have formed the backbone of my work at UT Austin. First, we studied singlet exciton fission (SF) in a common perylenediimide (PDI) derivative often used as a molecular organic semiconductor, C8-PDI, using pump-probe spectroscopy to model SF and singlet-singlet annihilation (SSA). Therein, we were surprised to report a SF rate orders of magnitude slower than predicted by computational studies of PDI dimers. In Chapter 3, we study a suite of six PDI derivatives that adopt different crystal structures to further assess the nature of SF in polycrystalline films grown on sapphire and fused-quartz. We developed a kinetic model across the PDI series based on the analysis of time-resolved photoluminescence, free from SSA contributions to kinetics that must otherwise be carefully modelled for TA data of these films. We confirm that Redfield theoretic approximations of the SF rate in these materials better captures the trend in kinetics implying the important role the charge-transfer character in these excitons play in mediating the process. The variation in intermolecular organization and associated changes in the Coulombic and exchange coupling between nearest-neighbor molecules correctly captures a qualitative trend in the observed SF rate, though the observed rates are an order of magnitude smaller than expected. We propose this discrepancy arises because the PDI dimer model we use for our predictive model for polycrystalline PDI thin films neglects changes in the excited state character/energetics that become important in strongly interacting molecular solids. The contents of Chapter 4 are then a study of colloidal suspensions of PbS nanocrystals (NC) decorated with a TIPS-pentacene ligand, 2-CP. We set out to search for evidence of the formation of spin-triplet excitons on the 2-CP ligands after photoexcitation of the PbS NC. Triplet exciton formation is observed with no clear observation of an intermediate charge separated species. However, an intermediary state is observed and carefully assigned to a surface associated state on the PbS NC. This hypothesis is further supported by the presence of a multitude of triplet excited states found in constrained DFT computations and fluence dependent pump-probe data providing evidence for the photopassivation the intermediate surface state. In totality, my studies have elucidated excited state dynamics in singlet fission capable polycrystalline films of perylenediimide molecules and contributed to our growing understanding of triplet exciton transfer between PbS NCs and molecular ligands.

description: Differences in resource endowment between regions influence the technologies applied in agriculture and cause location-specific effects on production and technical change. Access to technologies may also differ within regions because producers may apply different technologies in production due to different characteristics. Within this setting, we extend the existing literature by considering that producers face region- and farm-specific production frontiers. The treatment of essentially heterogeneous technical efficiency (TE) is performed following a two-step procedure. First, a random coefficient specification of the production technology is used to measure the interactions of technology adoption with time, input factors and output. Second, linear programming techniques are employed to envelop the optimal level of technology. This procedure is applied to household-level data from eastern, central and western provinces in China. Our results provide evidence that technical efficiency is significantly affected by farm heterogeneity. This factor influences TE directly as a producer-specific input, and indirectly through interaction with observable inputs such as land, labor, capital and intermediate inputs. Our results also prove the assumption that farming technology exhibits region-specific characteristics. Furthermore, there is a disparity of TE across provinces that narrows over the study period and is driven by the shifts of production to the metafrontier.
Survivability of radio-loud planetary cores orbiting white dwarfs

description: The discovery of the intact metallic planetary core fragment orbiting the white dwarf SDSS J1228+1040 within one Solar radius highlights the possibility of detecting larger, unfragmented conducting cores around magnetic white dwarfs through radio emission. Previous models of this decades-old idea focussed on determining survivability of the cores based on their inward Lorentz drift towards the star. However, gravitational tides may represent an equal or dominant force. Here, we couple both effects by assuming a Maxwell rheological model and performing simulations over the entire range of observable white dwarf magnetic field strengths (10^3 -- 10^9 G) and their potential atmospheric electrical conductivities (10^{-1} -- 10^4 S/m) in order to more accurately constrain survivability lifetimes. This force coupling allows us to better pinpoint the physical and orbital parameters which allow planetary cores to survive for over a Gyr, maximizing the possibility that they can be detected. The most robust survivors showcase high dynamic viscosities (>~ 10^{24} Pa*s) and orbit within kG-level magnetic fields.

description: R. Labouvie et al. [Phys. Rev. Lett. 116, 235302 (2016)] have described an experiment with a weakly interacting Bose-Einstein condensate trapped in a one-dimensional optical lattice with localized loss created by a focused electron beam. We show that by setting suitable initial currents between neighboring sites it is possible to create $\mathcal{PT}$-symmetric quasi-stationary and $\mathcal{PT}$-symmetry broken decaying states in an embedded two-mode subsystem. This subsystem exhibits gain provided by the coupling to the reservoir sites and localized loss due to the electron beam, and shows the same dynamics as a non-Hermitian two-mode system with symmetric real and antisymmetric imaginary time-independent potentials, except for a proportionality factor in the chemical potential. We also show that there are three other equivalent scenarios, and that the presence of a localized loss term significantly reduces the size of the condensate required for the realization.

description: This article investigates which factors influence the economic growth of organic farms. Organic farming has experienced a substantial growth in Germany since the beginning of the 1990s until today. Most organic farms are concentrated in the southern region of the country, Bavaria and Baden-Wuerttemberg. While some of these farms have expanded their business size, others have contracted, reconverted to conventional or ceased to operate. Using a panel data of 318 farms and a System GMM method, the economic growth of organic farms is analyzed. Regression results suggest that organic farms with high revenue from agriculture are less likely to grow than smaller farms. Growth is influenced by livestock intensity, multiple job holding, share of grasslands areas, soil quality and agri-environmental payments for organic farming.

description: Can the SO(10) model with one {\bf 10} and one {\bf 126} Higgs scalars give the observed masses and mixings of quarks and leptons without any other additional Higgs scalars? Recently, at least, for quarks and charged leptons, it has been demonstrated that it is possible. However, for the neutrinos, it is usually said that parameters which are determined from the quark and charged lepton masses cannot give the observed large neutrino mixings. This problem is systematically investigated, and it is concluded that the present data cannot exclude SO(10) model with two Higgs scalars although it cannot give the best fit values of the data.

description: Azobenzene has become a ubiquitous component of functional molecules and polymeric materials because of the light-induced trans-cis isomerization of the diazene group. In contrast, there are very few applications utilizing azobenzene luminescence, since the excitation energy typically dissipates via nonradiative pathways. Inspired by our earlier studies with 2,2'-bis[N,N'-(2-pyridyl)methyl]diaminoazobenzene (AzoAMoP) and related compounds, we investigated a series of five aminoazobenzene derivatives and their corresponding silver complexes. Four of the aminoazobenzene ligands, which exhibit no emission under ambient conditions, form silver coordination polymers that are luminescent at room temperature. AzoAEpP (2,2'-bis[N,N'-(4-pyridyl)ethyl]diaminoazobenzene) assembles into a three-dimensional coordination polymer (AgAAEpP) that undergoes a reversible loss of emission upon the addition of metal-coordinating analytes such as pyridine. The switching behavior is consistent with the disassembly and reassembly of the coordination polymer driven by displacement of the aminoazobenzene ligands by coordinating analytes.

description: Risk management strategies are of increasing importance in agriculture. An important question is, what type of risk management strategies are required to reduce farmers’ income risks. Applying a variance decomposition approach using data of more than 3000 Swiss farms over a five year time period, this paper quantifies the direct and indirect effects of yields, prices and costs on net revenue variability at the farm‐level. We find that costs play only a minor role in determining income variability but price and yield risks are of outmost importance and very crop‐specific. For instance, price risks dominate for intensive wheat and sugar beet producer; while corn and barley producer tend to suffer more form production risks. Group comparisons and logistic regressions results show that more intensively producing farms tend to suffer more from price risk, while yield risks are dominant for less intensive producers.

description: We explore skewed parton distributions for simple, model wave-functions in a truncated two-body Fock space. Consideration of non-Gaussian wave functions is our main emphasis, from which we observe the distributions are bimodal (there can be two distinct peaks) in the Fock-space diagonal overlap region (x > xi). We demonstrate that this behavior arises from convoluting two light-front wave functions to form the skewed parton distribution. Furthermore, the factorization Ansaetze, which have been used often, are shown not to hold. At high t, we can write the skewed parton distribution in terms of quark distribution amplitudes and perturbative wave functions thereby providing new tests.

description: The conjugated forces model (CFM) capable of reproducing bypassing behaviour is proposed and adopted to simulate pedestrian evacuation. Primarily, the concept of collision and evading and surpassing behaviour is particularly defined to describe the proposed CFM. A pedestrian whose behaviour can be described by the CFM will change his desired direction when confronted with a collision, and choose to actively bypass others. Secondly, pedestrian movement in a passageway is simulated to testify the capacity of the CFM to reproduce microscopic bypassing behaviour, and the bypassing parameter is then introduced to describe different movement strategies. Finally, Evacuation form a one-exit room is simulated to find the optimal bypassing strategy. It is concluded that the optimal bypassing strategy varies with different exit width and initial pedestrian number.

description: TETRAGONISCA ANGUSTULA (LATREILLE)   Figures 7, 8, 23–26
 DIAGNOSIS: The egg of T. angustula (figs. 7, 8) is the smallest of the four species of meliponine eggs described here. It is linear in form with the posterior end narrower than the anterior end, as is the case with the slightly longer and more oval egg of S. pectoralis (figs. 5, 6).
DESCRIPTION: Color white; chorion faintly uneven when viewed at high magnification with stereomicroscope. Shape (figs. 7, 8) moderately elongate; when viewed from above or below, with sides converging slightly and symmetrically toward posterior end; long axis of egg perhaps slightly curved (possibly accident of preservation) in lateral view (fig. 8). Dimensions of 10 specimens selected at random: length 1.03 mm, range 1.0–1.05 mm, maximum width 0.35 mm, range 0.32–0.36.
When viewed with SEM, most of chorion with distinct pattern of elevated hexagons (fig. 23) but extreme posterior end smooth (fig. 27); micropylar area slightly bulging (fig. 24) with micropyle slightly recessed (fig. 25).

description: Familial exudative vitreoretinopathy (FEVR) is a rare retinal disorder characterised by incomplete retinal vascular development. Symptoms vary widely from none to blindness even within the same family. Multiple genes related to the Wnt pathway have been found to be associated with FEVR. Recent studies identified tetraspanin 12 (TSPAN12) as a cause of the autosomal dominant inheritance form of FEVR. Here, we describe a novel TSPAN12 mutation in a Chinese family with FEVR. Targeted next-generation sequencing was performed on the proband to define the TSPAN12 mutation. Sanger sequencing was used to confirm the mutation in five family members (I-1, II-2, II-3, II-4, and III-3) in a three-generation FEVR pedigree. Ophthalmologic examinations and diagnostic imaging related to FEVR were performed. The proband (II-3) was a 32-year-old man with early-stage peripheral retinal vascular anomalies, but no visual acuity problems. DNA sequencing identified a heterozygous missense mutation (c.241 G > A: p.Gly81Arg) in TSPAN12 in the proband. The mutation was in a highly conserved region and was predicted to affect the normal protein structure. The patient’s father and daughter were also diagnosed with FEVR and carried the same mutation, with varying degrees of manifestations. Other family members had good vision and normal eye examinations with negative genetic testing. We identified a novel missense mutation in TSPAN12 associated with autosomal dominant FEVR. These results will facilitate the diagnosis, prognosis, and genetic counselling for this disease. Further studies are needed to identify the mechanisms underlying clinical variations among individuals in the family.

description: This study estimates the impact of the adoption of SSNM practices on rice production of smallholder farmers in Vietnam using cross-section household data (n = 371) gathered from the provinces of Ha Nam and Ha Tay in the Red River Delta. Specifically, it investigates the economic impact of SSNM, focusing on SSNM-induced changes in the yield, profit, nitrogen use and pesticide use of farmers. The instrumental variables (IV) approach is used to achieve this objective because it deals with endogeneity and self-selection bias present in the study. SSNM improves the paddy yield of farmers by 0.6 tons per hectare and profit by $150 per hectare. It has no statistically significant effect on the amount of pesticide and nitrogen use of farmers. The higher profits for adopters versus non-adopters of SSNM arise from increased grain yield rather from reducing fertilizer costs and pesticide costs. Results of the impact analysis identified several directions that can be pursued to improve further the adoption of SSNM.

description: Refresh is an important operation to prevent loss of data in dynamic random-access memory (DRAM). However, frequent refresh operations incur considerable power consumption and degrade system performance. Refresh power cost is especially significant in high-capacity memory devices and battery-powered edge/mobile applications. In this paper, we propose a principled approach to optimizing the refresh power allocation. Given a model for the bit error rate dependence on power, we formulate a convex optimization problem to minimize the word mean squared error for a refresh power constraint; hence we can guarantee the optimality of the obtained refresh power allocations. In addition, we provide an integer programming problem to optimize the discrete refresh interval assignments. For an 8-bit accessed word, numerical results show that the optimized nonuniform refresh intervals reduce the refresh power by 29% at a peak signal-to-noise ratio of 50dB compared to the uniform assignment.

description: Older GCE models predict [K/Fe] ratios as much as 1 dex lower than those inferred from stellar observations. Abundances of potassium are mainly based on analyses of the 7698 $Å$ resonance line, and the discrepancy between models and observations is in part caused by the LTE assumption. We study the statistical equilibrium of KI, focusing on the non-LTE effects on the $7698 \ Å$ line. We aim to determine how non-LTE abundances of K can improve the analysis of its chemical evolution, and help to constrain the yields of models. We construct a model atom that employs the most up-to-date data. In particular, we calculate and present inelastic e+K collisional excitation cross-sections from the convergent close-coupling and the $B$-Spline $R$-matrix methods, and H+K collisions from the two-electron model. We constructed a fine grid of non-LTE abundance corrections that span $4000
