description: In these notes a recently developed technique for the computation of line bundle-valued sheaf cohomology group dimensions on toric varieties is reviewed. The key result is a vanishing theorem for the contributing components which depends on the structure of the Stanley-Reisner ideal generators. A particular focus is placed on the (simplicial) Alexander duality that provides a central tool for the two known proofs of the algorithm.

description: Results of speckle observations at the 4.1-m SOAR telescope in 2012 (158 measures of 121 systems, 27 non-resolutions) are reported. The aim is to follow fast orbital motion of recently discovered or neglected close binaries and sub-systems. Here 8 previously known orbits are defined better, two more are completely revised, and five orbits are computed for the first time. Using differential photometry from Hipparcos or speckle and the standard relation between mass and absolute magnitude, the component's masses and dynamical parallaxes are estimated for all 15 systems with new or updated orbits. Two astrometric binaries HIP 54214 and 56245 are resolved here for the first time, another 8 are measured. We highlight several unresolved pairs that may actually be single despite multiple historic measures, such as 104 Tau and f Pup AB. Continued monitoring is needed to understand those enigmatic cases.

description: Puiseux series are power series in which the exponents can be fractional and/or negative rational numbers. Several computer algebra systems have one or more built-in or loadable functions for computing truncated Puiseux series -- perhaps generalized to allow coefficients containing functions of the series variable that are dominated by any power of that variable, such as logarithms and nested logarithms of the series variable. Some computer-algebra systems also offer functions that can compute more-general truncated recursive hierarchical series. However, for all of these kinds of truncated series there are important implementation details that haven't been addressed before in the published literature and in current implementations. For implementers this article contains ideas for designing more convenient, correct, and efficient implementations or improving existing ones. For users, this article is a warning about some of these limitations. Many of the ideas in this article have been implemented in the computer-algebra within the TI-Nspire calculator, Windows and Macintosh products.

description: We study a Lie algebra of formal vector fields $W_n$ with its application to the perturbative deformed holomorphic symplectic structure in the A-model, and a Calabi-Yau manifold with boundaries in the B-model. We show that equivalent classes of deformations are describing by a Hochschild cohomology theory of the DG-algebra ${\mathfrak A} = (A, Q)$, $Q =\bar{\partial}+\partial_{\rm deform}$, which is defined to be the cohomology of $(-1)^n Q +d_{\rm Hoch}$. Here $\bar{\partial}$ is the initial non-deformed BRST operator while $\partial_{\rm deform}$ is the deformed part whose algebra is a Lie algebra of linear vector fields ${\rm gl}_n$. We show that equivalent classes of deformations are described by a Hochschild cohomology of ${\mathfrak A}$, an important geometric invariant of the (anti)holomorphic structure on $X$. We discuss the identification of the harmonic structure $(HT^\bullet(X); HΩ_\bullet(X))$ of affine space $X$ and the group ${\rm Ext}_{X^{2}}^n({\cO}_{\triangle}, {\cO}_{\triangle})$ (the HKR isomorphism), and bulk-boundary deformation pairing.

description: Fragmentation of the dipole strength in the N=82 isotones 140Ce, 142Nd and 144Sm is calculated using the second random-phase approximation (SRPA). In comparison with the result of the random-phase approximation (RPA), the SRPA provides the additional damping of the giant dipole resonance and the redistribution of the low-energy dipole strength. Properties of the low-energy dipole states are significantly changed by the coupling to two-particle-two-hole (2p2h) states, which are also sensitive to the correlation among the 2p2h states. Comparison with available experimental data shows a reasonable agreement for the low-energy E1 strength distribution.

description: There is a wide consensus in the astrophysics community that the mechanism underlying the observed Classical Nova eruptions is a surface thermonuclear runaway. We start this short review with the main observational facts that lead to the theoretical model of a thermonuclear runaway that takes place in an accreted hydrogen rich envelope placed on top of a cool degenerate core of a white dwarf. According to the theory, the accreted envelope becomes unstable to convection days to weeks prior to the runaway. During the extreme stages of the runaway itself, when the burning is most efficient, the envelope is fully convective. Therefore, the elements processed under such extreme conditions are lifted to the outermost regions of the star. A significant fraction of the envelope is ejected during the outburst. The complicated combination of hydrodynamic instabilities and explosive hydrogen burning, close to the surface of the star, gives us a unique opportunity to study this complex reactive flow. The range of core masses, core temperatures and accretion rates introduce a whole range of burning temperatures and densities. Following the description of the "standard" cases, we then focus on rare, but still possible, portions of the relevant parameter space, in which "breakout" of the traditional CNO cycle can occur and lead to heavy element enrichment patterns caused only by breakout burning. We conclude our review with the main challenges that nova theorists face today, with special emphasis on problems related to the nucleosynthesis issues.

description: With the advent of large-collecting-area instruments, the number of objects that can be reached by optical long-baseline interferometry is steadily increasing. We present here a few results on massive binary stars, showing the interest of using this technique for studying the insight of interactions in these systems. Indeed, many massive stars with extended environments host, or are suspected to host, companion stars. These companions could have an important role in shaping the circumstellar environment of the system. These examples provide a view in which binarity could be an ingredient, among many others, for the activity of these stars.

description: Commercial truck parking is a safety issue, since trucks are involved in approximately 10% of all fatal accidents on interstates and parkways in Kentucky. Drivers experience schedule demands and long hours on the road, yet they cannot easily determine available parking locations. The objective of this study was to identify information related to parking demand, locations with documented or potential safety issues, and potential countermeasures. The literature review indicated substantial research has been done on commercial vehicle parking, and works have outlined the necessary facilities to accommodate trucks before drivers exceed their allowable hours of driving. Attention to commercial truck parking became a priority with SAFETEA-LU, and this focus continued with the inclusion of Jason’s Law as part of MAP-21.  Surveys were conducted to determine how frequently commercial vehicles used parking facilities on interstates in Kentucky. The surveys focused on the state’s two primary north-south interstates (I-65 and I-75). Data samples were also obtained from the other interstates in Kentucky (I-24, I-64, and I-71). Of the 4715 parking spaces surveyed during daytime observations, 2143 were in use, or 45 percent. Of 7,844 parking spaces surveyed during nighttime observations, 6803 were in use, or 87 percent. Crash data were analyzed for the period 2010-2013. Of 848 crashes that were either shoulder-related or fatigue-related, collision reports were reviewed. 239 crashes were related to commercial truck parking. Two-thirds of all crashes included in the analysis occurred on I-75, I-65, I-64, and I-71. Crash cluster locations appeared to be directly related to proximity and usage rate of parking facilities. To address truck parking demand and to improve safety, the following general recommendations were identified in the review of literature: 1) use public and private parking areas to increase capacity, 2) use ITS to improve use of parking facilities, 3) provide realtime information that informs truck drivers of parking facility locations with available spaces, 4) combine GPS tracking with electronic communication to notify truckers of nearest parking, and 5) monitor parking usage rates to determine future needs. Part of the literature review included recommendations from truck drivers. Based on observations at sites on interstates in Kentucky, several locations would benefit from increasing the number of parking spaces, including a number of locations on I-64, I-65, I-71 and I-75. Any site that had 90 percent or more of its spaces used during the surveys could be a candidate for an expansion of existing parking spaces or for development of a new facility to accommodate more parking.

description: Social anxiety disorder is characterized by a persistent fear and avoidance of social situations, but available treatment options are rather unspecific. Using an established mouse social fear conditioning (SFC) paradigm, we profiled gene expression and chromatin alterations after the acquisition and extinction of social fear within the septum, a brain region important for social fear and social behaviors. Here, we particularly focused on the successful versus unsuccessful outcome of social fear extinction training, which corresponds to treatment responsive versus resistant patients in the clinics. Validation of coding and non-coding RNAs revealed specific isoforms of the long non-coding RNA (lncRNA) Meg3 regulated, depending on the success of social fear extinction. Moreover, PI3K/AKT was differentially activated with extinction success in SFC-mice. In vivo knockdown of specific Meg3 isoforms increased baseline activity of PI3K/AKT signaling, and mildly delayed social fear extinction. Using ATAC-Seq and CUT&RUN, we found alterations in the chromatin structure of specific genes, which might be direct targets of lncRNA Meg3.

description: Iron (II) complexes with substituted tris(pyrazolyl) ligands, which exhibit a thermally driven transition from a low-spin state at low temperatures to a high-spin state at elevated temperatures, have been studied by Mössbauer spectroscopy and magnetic susceptibility measurements. From the observed spectra the molar high-spin fraction and the transition temperature have been extracted. All substituents, except for bromine, lead to a decrease of the transition temperature. Density functional calculations have been carried out to compare the experimentally observed shifts of the transition temperature with those derived from theory.

description: We present the results of a study designed to measure the impact of interruptive advertising on consumers' willingness to pay for products bearing the advertiser's brand. Subjects participating in a controlled experiment were exposed to ads that diverted their attention from a computer game they were testing. We measured subjects' willingness to pay for a good associated with the advertised brand. We found that the ads significantly lowered the willingness to pay for goods associated with the advertising brand. We do not find conclusive evidence that providing some level of user control over the appearance of ads mitigates the negative impact of ad interruption. Our results contribute to the research on the economic impact of advertising, and introduce a method of measuring actual (as opposed to self-reported) willingness to pay in experimental marketing research. © 2011 Direct Marketing Educational Foundation, Inc.
Best Practices for the Implementation of the REAL ID Act

description: The REAL ID Act specifies the minimum standards that must be used to produce and issue driver’s license and identification cards that are REAL ID compliant. Beginning in 2020, if a person does not possess a form of identification that meets REAL ID standards they will not be able to board an aircraft that is regulated by the Federal Aviation Administration. Currently, of the 56 states and jurisdictions required to implement the REAL ID Act, only 23 are in compliance. Although the Commonwealth of Kentucky has not yet implemented the REAL ID Act, an extension allowing Federal agencies to accept state driver’s licenses is currently in effect. This report summarizes the eight REAL ID requirements, discusses the results of a survey that asked compliant states about their implementation experiences, identifies different strategies for implementation, and proposes recommendations. This should begin with development of a state security plan and execution of a public information campaign about REAL ID. It is recommended that Kentucky require Division of Driver Licensing (DLL) field offices to handle REAL ID applications, offer an online renewal system, and create a centralized distribution of driver’s licenses and identification cards. Several KY Statutes will have to be amended to allow for changes in license renewal cycles, third party vendor distribution, and the resulting changes in license fees.

description: We examine spatial localisation and dynamical stability of Bose-Einstein condensates of exciton-polaritons in microcavities under the condition of off-resonant spatially inhomogeneous optical pumping both with and without a harmonic trapping potential. We employ the open-dissipative Gross-Pitaevskii model for describing an incoherently pumped polariton condensate coupled to an exciton reservoir, and reveal that spatial localisation of the steady-state condensate occurs due to the effective self-trapping created by the polariton flows supported by the spatially inhomogeneous pump, regardless of the presence of the external potential. A ground state of the polariton condensate with repulsive interactions between the quasiparticles represents a dynamically stable bright dissipative soliton. We also investigate the conditions for sustaining spatially localised structures with non-zero angular momentum in the form of single-charge vortices.

description: Researches on signed languages still strongly dissociate lin- guistic issues related on phonological and phonetic aspects, and gesture studies for recognition and synthesis purposes. This paper focuses on the imbrication of motion and meaning for the analysis, synthesis and evaluation of sign language gestures. We discuss the relevance and interest of a motor theory of perception in sign language communication. According to this theory, we consider that linguistic knowledge is mapped on sensory-motor processes, and propose a methodology based on the principle of a synthesis-by-analysis approach, guided by an evaluation process that aims to validate some hypothesis and concepts of this theory. Examples from existing studies illustrate the di erent concepts and provide avenues for future work.

Two-loop Corrections to the B to pi Form Factor from QCD Sum Rules on the Light-Cone and |V(ub)|

description: We calculate the leading-twist O(alphas^2 beta0) corrections to the B to pi transition form factor f+(0) in light-cone sum rules. We find that, as expected, there is a cancellation between the O(alphas^2 beta0) corrections to fB f+(0) and the large corresponding corrections to fB, calculated in QCD sum rules. This suggests the insensitivity of the form factors calculated in the light-cone sum rules approach to this source of radiative corrections. We further obtain an improved determination of the CKM matrix element |V(ub)|, using latest results from BaBar and Belle for f+(0)|V(ub)|.

description: The Neutron Spin Echo (NSE) variant MIEZE (Modulation of IntEnsity by Zero Effort), where all beam manipulations are performed before the sample position, offers the possibility to perform low background SANS measurements in strong magnetic fields and depolarising samples. However, MIEZE is sensitive to differences \DeltaL in the length of neutron flight paths through the instrument and the sample. In this article, we discuss the major influence of \DeltaL on contrast reduction of MIEZE measurements and its minimisation. Finally we present a design case for enhancing a small-angle neutron scattering (SANS) instrument at the planned European Spallation Source (ESS) in Lund, Sweden, using a combination of MIEZE and other TOF options, such as TISANE offering time windows from ns to minutes. The proposed instrument allows studying fluctuations in depolarizing samples, samples exposed to strong magnetic fields, and spin-incoherently scattering samples in a straightforward way up to time scales of \mus at momentum transfers up to 0.01 Å-1, while keeping the instrumental effort and costs low.

description: Theoretical uncertainties in the predictions of relativistic mean-field models are estimated using a chi-square minimization procedure that is implemented by studying the small oscillations around the chi-square minimum. By diagonalizing the matrix of second derivatives, one gains access to a wealth of information---in the form of powerful correlations---that would normally remain hidden. We illustrate the power of the {\sl covariance analysis} by using two relativistic mean-field models: (a) the original linear Walecka model and (b) the accurately calibrated FSUGold parametrization. In addition to providing meaningful theoretical uncertainties for both model parameters and predicted observables, the covariance analysis establishes robust correlations between physical observables. In particular, we show that whereas the correlation coefficient between the slope of the symmetry energy and the neutron-skin thickness of Lead is indeed very large, a 1% measurement of the neutron radius of Lead may only be able to constrain the slope of the symmetry energy to about 30%.

description: In an effort to elucidate the origin of the Curie-like paramagnetism that is generic for heavily-overdoped cuprates, we have performed high transverse-field muon spin rotation (TF-muSR) measurements of La2-xSrxCuO4 single crystals over the Sr content range 0.145 < x < 0.33. We show that the x-dependence of the previously observed field-induced broadening of the internal magnetic field distribution above the superconducting transition temperature Tc reflects the presence of two distinct contributions. One of these becomes less pronounced with increasing x and is attributed to diminishing antiferromagnetic correlations. The other grows with increasing x, but decreases above x ~ 0.30, and is associated with the Curie-like term in the bulk magnetic susceptibility. In contrast to the Curie-like term, however, this second contribution to the TF-muSR line width extends back into the underdoped regime. Our findings imply a coexistence of antiferromagnetically correlated and paramagnetic moments, with the latter becoming dominant beyond x ~ 0.185. This suggests that the doped holes do not neutralize all Cu spins via the formation of Zhang-Rice singlets. Moreover, the paramagnetic component of the TF-muSR line width is explained by holes progressively entering the Cu 3d_{x^2-y^2} orbital with doping.

description: We theoretically investigate the possibility of generating pulses in an excitable (asymmetric) semiconductor ring laser (SRL) using optical trigger pulses. We show that the phase difference between the injected field and the electric field inside the SRL determines the direction of the perturbation in phase space. Due to the folded shape of the excitability threshold, this has an important influence on the ability to cross it. A mechanism for exciting multiple consecutive pulses using a single trigger pulse (i.e. multi pulse excitability) is revealed. We furthermore investigate the possibility of using asymmetric SRLs in a coupled configuration, which is a first step toward an all-optical neural network using SRLs as building blocks.

description: In recent years, a significant amount of attention has been given to the relationship between art and labour, to the nature of artistic labour, and to the feminist critique of Marxist thought on reproduction. Yet in different ways, these analyses have been based on a hylomorphic model of creation, in that they take for granted the domination of form over inert matter, and characterise the labour of maintenance as repetitive toil,which is counterpoised to the inventive creative work of the artist.This practice-based doctoral project asks how furnished spaces such as the studio, workshop and home contribute to t he processes from which art works emerge. The project examines the ‘reproductive’ work involved in furnishing working spaces and maintaining t hem, through engaging in aseries of practice-based approaches (painting, drawing and print-making). It initiated from an exploration of the constraints and opportunities of domestic arrangements for the production of art works through the work Vertical Studio (2010 onwards), which furnishes a domestic space as a working home studio,and went on to explore existing furnished spaces such as the print-making workshop, testing their affordances with a set of rule-based procedures.For the physicist Karen Barad, apparatuses of production are labourers that make unpredictable and irreplaceable contributions to the processes that they facilitate. Drawing on Barad’s work I demonstrate that rather thanmerely containing furniture, materials, tools and machines, furnished spaces are also labourers that do some of the work involved in the emergence of art works. However, there are no ‘raw’ materials in the studio, the workshop, or the home: and I draw on the philosopher Gilbert Simondon to arguethat all matter is ‘worked’ matter, and that materials are produced and prepared. Drawing on Simondon’s critique of the separation of form and matter in hylomorphism, and his re-evaluation of maintenance, I re-examine the productivity of the work of setting up and maintaining furnished spaces.There is a double-sidedness that connects the work that things do to the work of making things work: by defining both the home and studio as furnished spaces that work, the project suggests a new way of advancing beyond the distinction between productive and reproductive labour, and reveals reproductive labour as a set of practices the productivity of which is concealed and underplayed in current understandings of artistic labour.

description: Kentucky's bridges continue to age and experience distress. The intrusion of chlorides into concrete remains the primary mechanism for deterioration. It leads to reinforcing steel corrosion that damages the adjoining concrete structure. This study found problematic chloride concentrations in Kentucky concrete bridge elements (decks, pier caps, abutments). Chloride levels have been found at concentrations sufficient to initiate reinforcing steel corrosion. In some cases, chloride concentrations were sufficient to cause accelerated corrosion and produce major section loss of reinforcing steel. Advanced stages of corrosion such as these typically require costly repairs and maintenance to extend the service life of bridges.  Field inspections and laboratory analyses conducted during this study verified the ongoing problem of concrete deterioration across bridges within Kentucky's transportation network.

description: We present the optical to mid-infrared SEDs of 11 debris disk candidates from $Spitzer$ SWIRE fields. All these candidates are selected from SWIRE 24$μ$m sources matched with both the SDSS star catalog and the 2MASS point source catalog. They show an excess in the mid-infrared at 24$μ$m ($K_S$-[24]$_{Vega}$ $\ge$ 0.44) indicating the presence of a circumstellar dust disk. The observed optical spectra show that they are all late type main-sequence stars covering the spectral types of FGKM. Their fractional luminosities are well above 5$\times10^{-5}$, even up to the high fractional luminosity of 1$\times10^{-3}$. The high galactic latitudes of SWIRE fields indicate that most of these candidates could belong to the oldest stars in the thick disk. Our results indicate that the high fractional luminosity debris disks could exist in the old solar-like star systems, though they are now still quite rare. Their discoveries at high-galactic latitudes will also provide us an excellent opportunity to the further studies of properties and evolution of the debris disk in the ISM poor environments.

description: The Department of Environmental Analysis at the Kentucky Transportation Cabinet has expressed an interest in feature-recognition capability because it may help analysts identify environmentally sensitive features in the landscape, including those relating to historic preservation, archaeology, endangered species habitat, and geology. LIDAR Analyst and Feature Analyst are a pair of geoprocessing software packages that have been developed by Textron Systems. Using this software, users can use LIDAR data to identify finely-scaled user-specified features. The software’s automated feature extraction saves time that might otherwise be spent manually analyzing images and digitizing features.  This report explores the capabilities and accuracy of this software by using LIDAR data to identify sinkholes throughout a small area in Kentucky. This report also discusses an alternative LIDAR-based geoprocessing methodology developed by the Kentucky Geological Society. The method relies on ArcGIS and Python scripting to identify sinkholes. The feasibility and applicability of these methodologies are compared, the workflow for each method is outlined, and the capabilities and limitations of each are noted. Sample results—the identification of sinkholes—from each methodology are presented. The research team found the batch processing capability built into LIDAR and Feature Analyst adequate and beneficial for smaller projects, such as projects that prioritize the extraction of buildings, trees, and forest regions.

description: In the present work we have demonstrated a possibility for real-time operation by orbital an-gular momentum (OAM) of optical beams via Pockels effect in solid crystalline materials. Basing on the analysis of optical Fresnel ellipsoid perturbed by conically shaped electric field, we have shown that the point groups of crystals convenient for the conversion of spin angular momentum (SAM) to OAM should contain a three-fold symmetry axis or a six-fold inversion axis. The results of our experimental studies and theoretical simulations of the SAM-to-OAM conversion efficiency carried out for LiNbO3 crystals agree well with each other.

The USCT committee was formed to create a monument to honor and bear the names of the more than 3,000 African American men who served in six regiments at Fort McPherson in Natchez. The regiments include: 6th U.S. Colored Heavy Artillery, 58th U.S. Colored Infantry, 70th U.S. Colored Infantry, 71st U.S. Colored Infantry, 63rd U.S. Colored Infantry, and the 64th U.S. Colored Infantry.

The monument will also bear the names of the Navy servicemen who were born in Natchez.

The USCT committee wants to identify the descendants of the Colored Troops who served in Natchez, as well as those who served in the Navy. Many of the soldiers were also from the surrounding counties.

description: We give a brief summary of the current status of the electron many-body problem in graphene. We claim that graphene has intrinsic dielectric properties which should dress the interactions among the quasiparticles, and may explain why the observation of electron-electron renormalization effects has been so elusive in the recent experiments. We argue that the strength of Coulomb interactions in graphene may be characterized by an effective fine structure constant given by $α^{\star}(\mathbf{k},ω)\equiv2.2/ε(\mathbf{k},ω)$, where $ε(\mathbf{k},ω)$ is the dynamical dielectric function. At long wavelengths, $α^{\star}(\mathbf{k},ω)$ appears to have its smallest value in the static regime, where $α^{\star}(\mathbf{k}\to0,0)\approx1/7$ according to recent inelastic x-ray measurements, and the largest value in the optical limit, where $α^{\star}(0,ω)\approx2.6$. We conclude that the strength of Coulomb interactions in graphene is not universal, but depends highly on the scale of the phenomenon of interest. We propose a prescription in order to reconcile different experiments.

description: We study effective potentials coming from compactifications of string theory. We show that, under mild assumptions, such potentials are bounded from below in four dimensions, giving an affirmative answer to a conjecture proposed by the second author in arXiv:0911.3378v4 [hep-th]. We also derive some sufficient conditions for the existence of critical points. All proofs and mathematical hypotheses are discussed in the context of their relevance to the physics of the problem.

Thermoelectric detection of ferromagnetic resonance of a nanoscale ferromagnet

description: We present thermoelectric measurements of the heat dissipated due to ferromagnetic resonance of a Permalloy strip. A microwave magnetic field, produced by an on-chip coplanar strip waveguide, is used to drive the magnetization precession. The generated heat is detected via Seebeck measurements on a thermocouple connected to the ferromagnet. The observed resonance peak shape is in agreement with the Landau-Lifshitz-Gilbert equation and is compared with thermoelectric finite element modeling. Unlike other methods, this technique is not restricted to electrically conductive media and is therefore also applicable to for instance ferromagnetic insulators.
