description: We consider the problem of discriminating two different quantum states in the setting of asymptotically many copies, and determine the optimal strategy that minimizes the total probability of error. This leads to the identification of the quantum Chernoff bound, thereby solving a long standing open problem. The bound reduces to the classical Chernoff bound when the quantum states under consideration commute. The quantum Chernoff bound is the natural symmetric distance measure between quantum states because of its clear operational meaning and because of the fact that it does not seem to share the undesirable features of other distance measures like the fidelity, the trace norm and the relative entropy.

HETEROTRIMERIC G-PROTEIN ?? SUBUNITS IN THE MOUSE PERIPHERAL OLFACTORY SYSTEM

Year: 2014

description: G-protein coupled signaling cascades are involved in a variety of activities in the sensory neurons of the peripheral olfactory system in mice, such as odor transduction and axonal projection. While the roles of heterotrimeric G-protein α-subunits, such as the olfactory G-protein α subunit (Gαolf) are well documented, very little is known about G?? subunits in the nasal sensory epithelium. Contrastingly, many studies in other systems have yielded a surge of data documenting the diverse functions of the known five G? and twelve G? subunits. Lin et al. in 2007 characterized a subset of olfactory sensory neurons in the main olfactory epithelium expressing the ion channel transient receptor potential channel (TRPM5). In other systems such as taste receptor cells, TRPM5 is a necessary downstream component of the phospholipase C (PLC) pathway which is thought to be activated by G??.  The heterotrimeric G-protein ? subunit G?13 is present in the cilia of olfactory sensory neurons (OSNs) of the main olfactory epithelium (MOE). This suggests that as an obligate dimer, G?? could be serving a role in the function of olfactory sensory neurons.  Although G?13 expression was found in the MOE, there was scattered and incomplete data regarding expression of other ? and ? subunits in both MOE and the vomeronasal organ (VNO).  In this work, using molecular techniques I provide a complete expression profile of the 5 different G? and 12 G? subunits in the MOE and VNO.  I show that multiple G? and G? subunits are expressed in the MOE and VNO in a cell type specific fashion.  Additionally, using molecular techniques and image analysis, I show that G?1 is dominant in both MOE and VNO.  Finally, using molecular and physiological approaches, I demonstrate that G?1 is essential to proper function of OSNs and also for glomerular formation in the main olfactory bulb (MOB).  My results demonstrate the heterotrimeric G-protein ?? subunits serve critical roles in olfaction.

description: Quantum theory stipulates that if two particles are identical in all physical aspects, the allowed states of the system are either symmetric or antisymmetric with respect to permutations of the particle labels. Experimentally, the symmetry of the states can be inferred indirectly from the fact that neglecting the correct exchange symmetry in the theoretical analysis leads to dramatic discrepancies with the observations. The only way to directly unveil the symmetry of the states for, say, two identical particles is through the interference of the original state and the physically permuted one, and measure the phase associated with the permutation process, the so-called particle exchange phase. Following this idea, we have measured the exchange phase of indistinguishable photons, providing direct evidence of the bosonic character of photons.

Female color preferences, ecological selection, and the evolution of male coloration in darters (Percidae: Etheostomatinae)

description: Since Charles Darwin's initial observations and hypotheses, the evolution of elaborate male coloration in sexually dichromatic species has been the subject of great interest. Of particular recent interest is how sexual and ecological selection interact to shape variation in male coloration between closely-related species. Using darters (Percidae: Etheostomatinae), a group of fishes that vary in male coloration as a model system, my goal is to determine how sexual and ecological selection interact to shape variation in male coloration between as well as within species lineages. In Chapter 1, I used reflectance spectrophotometry to examine correlations between spectral properties of orange and blue pigmentation in the rainbow darter, Etheostoma caeruleum, with parasite load and observed a correlation between the chroma of orange bars with parasite counts. In Chapter 2, I quantified color preferences in the darter genus Etheostoma to determine if the strengths of attraction to different colors coincided with variation in male coloration between species. The females of most achromatic species exhibited no significant color preferences, while chromatic species varied in preferences, with a positive association between the presence of red or orange on the flanks and preference for red detected across all species. In Chapter 3 I utilized phylogenetic comparative approaches and a laboratory experiment of predator color preferences to quantify the role of ecological variables in shaping variation in male coloration in darters. Compared to achromatic species, chromatic darters tend to inhabit environments where predation risk would be lower; specifically, shallower, faster-flowing upland streams with a lower number of overlapping predatory species. Additionally, a common darter predator, largemouth bass (Micropterus salmoides), exhibited significant preferences for red stimuli in a color choice experiment. Finally, in Chapter 4 I investigated color and size correlations, as well as male and female preferences for different sized and colored mates, in the Roanoke darter, Percina roanoka. Using digital photography I found correlations between size and color, but no preferences for larger or more colorful mates were observed in either sex. The results of this dissertation suggest that sexual and ecological selection do interact to shape color variation between darter species.

description: Pairs of photons entangled in their time-frequency degree of freedom are of great interest in quantum optics research and applications, due to their relative ease of generation and their high capacity for encoding information. Here we analyze, both theoretically and experimentally, the behavior of phase-insensitive spectrally-resolved interferences arising from two pairs of time-frequency entangled photons. At its core, this is a multimode entanglement swapping experiment, whereby a spectrally resolved joint measurement on the idler photons from both pairs results in projecting the signal photons onto a Bell state whose form depends on the measurement outcome. Our analysis is a thorough exploration of what can be achieved using time-frequency entanglement and spectrally-resolved Bell-state measurements.

description: The growing prevalence of ultra-processed foods in Uganda is driving the double burden of malnutrition. Overweight and obesity are on the rise while the intake of micronutrients remains insufficient. Simultaneously, jackfruits that are rich in minerals and vitamins remain underutilized. Its large size, sticky insides, and high perishability make it challenging to handle and cause high postharvest losses. In an attempt to address both issues, the present study investigates the potential of long-lasting, nutritious, and sugar-free jackfruit-nut-bars (JNBs) as a channel to enhance and promote the utilization of jackfruit, and provide healthier options of processed foods. To analyze consumer demand for the products, we first assess the sensory perception of four different JNBs at a university campus in Uganda. We then use Van Westendorp’s price sensitivity meter to elicit consumers’ willingness to pay (WTP) and identify factors shaping their demand. The results show that the sensory properties are, on average, rated positively, and price preferences are similar to established snacks. Based on our findings, we conclude that JNBs provide an option to enhance jackfruit utilization. A random effects model shows that WTP increases with sweetness, age, and frequency of snack consumption that JNBs can potentially substitute. These findings help future development and promotion of processed jackfruit products.

Prostate Cancer

description: Aurora-A is a serine/threonine kinase that has oncogenic properties in vivo. The expression and kinase activity of Aurora-A are up-regulated in multiple malignancies including prostate cancer, which is the most frequently diagnosed malignancy in men and the second leading cause of cancer death in the United States. Aurora-A is a key regulator of mitosis that localizes to the centrosome from the G2 phase of the cell cycle through mitotic exit and regulates mitotic spindle formation as well as centrosome separation. Overexpression of Aurora-A in multiple malignancies has been linked to higher tumor grade and poor prognosis through mechanisms that remain to be defined. Using an unbiased proteomics approach, we identified the protein Nuclear Mitotic Apparatus (NuMA) as a robust substrate of Aurora-A kinase. Using a small molecule Aurora-A inhibitor in conjunction with a Reverse In-gel Kinase Assay, we demonstrate that NuMA becomes hypo-phosphorylated in vivo upon Aurora-A inhibition. Using an alanine substitution strategy, we identified multiple Aurora-A phospho-acceptor sites in the C-terminal tail of NuMA. Functional analyses demonstrate that mutation of three of these Aurora A phospho-acceptor sites significantly diminishes cell proliferation. In addition, alanine mutation at these sites significantly increases the rate of apoptosis. Using confocal immunofluorescence microscopy, we show that the NuMA T1804A mutant mis-localizes to the cytoplasm in interphase nuclei in a punctate pattern. The identification of Aurora-A phosphorylation sites in NuMA that play a role in cell cycle progression and apoptosis provides new insights into Aurora-A function.

description: Nonlinear second-order ordinary differential equations are common in various fields of science, such as physics, mechanics and biology. Here we provide a new family of integrable second-order ordinary differential equations by considering the general case of a linearization problem via certain nonlocal transformations. In addition, we show that each equation from the linearizable family admits a transcendental first integral and study particular cases when this first integral is autonomous or rational. Thus, as a byproduct of solving this linearization problem we obtain a classification of second-order differential equations admitting a certain transcendental first integral. To demonstrate effectiveness of our approach, we consider several examples of autonomous and non-autonomous second order differential equations, including generalizations of the Duffing and Van der Pol oscillators, and construct their first integrals and general solutions. We also show that the corresponding first integrals can be used for finding periodic solutions, including limit cycles, of the considered equations.

description: The halide perovskites have truly emerged as efficient optoelectronic materials and show the promise of exhibiting nontrivial topological phases. Since the bandgap is the deterministic factor for these quantum phases, here we present a comprehensive electronic structure study using first-principle methods by considering nine inorganic halide perovskites CsBX$_3$ (B = Ge, Sn, Pb; X = Cl, Br, I) in their three structural polymorphs (cubic, tetragonal and orthorhombic). A series of exchange-correlations (XC) functionals are examined towards accurate estimation of the bandgap. Furthermore, while thirteen orbitals are active in constructing the valence and conduction band spectrum, here we establish that a four orbital based minimal basis set is sufficient to build the Slater-Koster tight-binding model (SK-TB), which is capable of reproducing the bulk and surface electronic structure in the vicinity of the Fermi level. Therefore, like the Wannier based TB model, the presented SK-TB model can also be considered as an efficient tool to examine the bulk and surface electronic structure of halide family of compounds. As estimated by comparing the model study and DFT band structure, the dominant electron coupling strengths are found to be nearly independent of XC functionals, which further establishes the utility of the SK-TB model.

description: The influence of vibrational motion on electron conduction through single molecules bound to metal electrodes is investigated employing first-principles electronic-structure calculations and projection-operator Green's function methods. Considering molecular junctions where a central phenyl ring is coupled via (alkane)thiol-bridges to gold electrodes, it is shown that -- depending on the distance between the electronic $π$-system and the metal -- electronic-vibrational coupling may result in pronounced vibrational substructures in the transmittance, a significantly reduced current as well as a quenching of negative differential resistance effects.

Analyses of assembly and functional defects in the ribosome of L4 and L22 mutant Escherichia coli strains

description: The ribosome is a complex macromolecule consisting of RNA and protein subunits that is responsible for translating the genetic code and protein synthesis. Within its large subunit, the exit tunnel exists as a conduit for nascent peptides to traverse before reaching the cytoplasm or membrane translocon.  The tips of the extended loops (also called tentacles) of two proteins, L4 and L22, contribute to the surface of the narrowest portion of Escherichia coli's exit tunnel. Mutations in the tentacles of the L4 and L22 proteins promote resistance to a class of antibiotics referred to as macrolides. Although the mutant strains have the advantage of growing in the presence of the antibiotic, erythromycin, they have the disadvantage of growing slower than the wildtype. The decreased rate of growth may be a reflection of structural changes within the 23S rRNA component of the large subunit induced by structural changes in L4 and L22, which in turn result in defects in ribosomal assembly and/or peptide synthesis.           My research involved determining whether the reduced growth rate can be attributed to the rate of peptide bond formation in the peptidyltransferase (PT) center and/or the reduced efficiency of ribosomal assembly. I used the peptidyltransferase assay on total ribosomes and purified subunits to evaluate the effect of the L4 and L22 mutations on ribosomal function. A decrease in PT activity was observed amongst all mutants. Analyses of Variance and Tukey's honestly significant difference test indicated that the differences between the wildtype and the mutants were statistically significant.  Additional statistical analyses revealed a strong positive correlation between my PT results and Zaman's data in which she used the ?-galactosidase induction assay to show a decreased rate of peptide chain elongation amongst the mutants.            I also used sucrose gradient analyses and primer extension to evaluate the effect of L4 and L22 mutations on ribosomal assembly and processing.  An abnormal peak was observed between the 30S and 50S peaks in the selected mutants.  Increased levels of precursor 23S rRNA were observed in the primer extension results of all mutants.  My results further substantiate the important roles that the L4 and L22 proteins provide in the function and assembly of the ribosome.

The methodology is comprehensively illustrated with a proof, to all orders in perturbation theory, that the beta function has no explicit dependence on either the seed action or details of the covariantization of the cutoff. The cancellation of these non-universal contributions is done in an entirely diagrammatic fashion.

description: The Lieb-Mattis theorem is generalized to an antiferromagnetic spin-ladder model with four-spin cyclic exchange interaction. We prove that for J>2K, the antiferromagnetic ordering of energy levels takes place separately in two sectors, which remain symmetric and antisymmetric under the reflection with respect to the longitudinal axis of the ladder. We prove also that at the self-dual point J=2K, the Lieb-Mattis rule holds in the sectors with fixed number of rung singlets. In both cases, it agrees with the similar rule for Haldane chain with appropriate spin number.

The mixture is composed by fermionic 40K and bosonic 87Rb. We observe effects of the large attractive and repulsive interaction energy across the resonance, such as collapse or a reduced spatial overlap of the mixture, and we accurately locate the resonance position and width. Understanding and controlling instabilities in this mixture opens the way to a variety of applications, including formation of heteronuclear molecular quantum gases.

description: A general approach to the design of accurate classical potentials for protein folding is described. It includes the introduction of a meaningful statistical measure of the differences between approximations of the same potential energy, the definition of a set of Systematic and Approximately Separable and Modular Internal Coordinates (SASMIC), much convenient for the simulation of general branched molecules, and the imposition of constraints on the most rapidly oscillating degrees of freedom. All these tools are used to study the effects of constraints in the Conformational Equilibrium Distribution (CED) of the model dipeptide HCO-L-Ala-NH2. We use ab initio Quantum Mechanics calculations including electron correlation at the MP2 level to describe the system, and we measure the conformational dependence of the correcting terms to the naive CED based in the Potential Energy Surface (PES) without any simplifying assumption. These terms are related to mass-metric tensors determinants and also occur in the Fixman's compensating potential. We show that some of the corrections are non-negligible if one is interested in the whole Ramachandran space. On the other hand, if only the energetically lower region, containing the principal secondary structure elements, is assumed to be relevant, then, all correcting terms may be neglected up to peptides of considerable length. This is the first time, as far as we know, that the analysis of the conformational dependence of these correcting terms is performed in a relevant biomolecule with a realistic potential energy function.

description: We present results from a blind, spectroscopic survey for redshift ~5.7 Lyman-alpha-emitting galaxies using the Inamori Magellan Areal Camera and Spectrograph. A total of ~200 square arcminutes were observed in the COSMOS and LCIRS fields using a narrowband filter, which transmits between atmospheric emission lines at 8190 A, and a mask with 100 longslits. This observing technique provides higher emission-line sensitivity than narrowband imaging and probes larger volumes than strong lensing. We find 170 emission-line galaxies and identify their redshifts spectroscopically. We confirm three Lyman-alpha emitting galaxies (LAEs), the first discovered using multislit-narrowband spectroscopy. Their line profiles are narrow, but fitted models suggest instrinsic, unattenuated widths 400 km/s FWHM. The red wing of the line profiles present features consistent with galactic winds. The star formation rates of these galaxies are at least 5-7 Msun/yr and likely a factor of two higher. We estimate the number density of L .ge. 5e42 erg/s LAEs is 9.0(+12,-4)e-5 Mpc-3 at redshift 5.7 and constrain the Schechter function parameters describing this population. Galaxies fainter than our detection limit may well be the primary source of ionizing photons at redshift ~ 6. We argue, however, that the break luminosity L* is not yet well constrained. If this break luminosity is near our detection limit, and somewhat lower than previous estimates, then the detected LAE population could be responsible for ionizing the intergalactic gas at redshift ~6. We discuss the potential of multislit-narrowband spectroscopy for deeper emission-line surveys.

description: Heavy ion collisions at the Large Hadron Collider (LHC) will produce strongly interacting matter at unprecedented energy densities. At LHC collision energies, new hard probes of the dense initial collision system will become readily available.

description: We present a new study of late-type eclipsing binary stars in the Small Magellanic Cloud (SMC) undertaken with the aim of improving the distance determination to this important galaxy. A sample of 10 new detached, double-lined eclipsing binaries indentified from the OGLE variable star catalogues and consisting of F- and G-type giant components has been analysed. The absolute physical parameters of the individual components have been measured with a typical accuracy of better than 3%. All but one of the systems consist of young and intermediate population stars with masses in the range of 1.4 to 3.8 M_Sun. This new sample has been combined with five SMC eclipsing binaries previously published by our team. Distances to the binary systems were calculated using a surface brightness - color calibration. The targets form an elongated structure, highly inclined to the plane of the sky. The distance difference between the nearest and most-distant system amounts to 10 kpc with the line of sight depth reaching 7 kpc. We find tentative evidence of the existence of a spherical stellar sub-structure (core) in the SMC coinciding with its stellar center, containing about 40% of the young and intermediate age stars in the galaxy. The radial extension of this sub-structure is ~1.5 kpc. We derive a distance to the SMC center of D_SMC=62.44 +/- 0.47 (stat.) +/- 0.81 (syst.) kpc corresponding to a distance modulus (m-M)_SMC=18.977 +/- 0.016 +/- 0.028 mag, representing an accuracy of better than 2%.

description: Excerpts from the report Introduction: Agriculture is the dominant activity in the 20 Republics of Latin America despite substantial development of minerals and industry. Nearly 60 percent of their 198 million people live in rural areas. Farm production provides one-fourth of the total gross national product. Except in Chile and Venezuela, its share exceeds that of any other economic activity; and except in those countries and Bolivia, one or a few agricultural exports provide most of the foreign exchange needed to import industrial and consumer goods essential to economic development. Corn is the predominant crop, found wherever it can be grown for food in most of the 20 Republics. Pulses, potatoes, mandioca (cassava), and plantains are widely grown as subsistence crops. Other cereals and oilseeds are important in temperate areas, particularly Argentina and Uruguay. Except in these two countries, per capita production of meat and animal products is low even though the region has nearly 20 percent of the world's cattle population. Better lands are often devoted to commercial production of coffee, bananas, sugarcane, cotton, and cacao.

description: Convolutional neural networks (CNN) are known to learn an image representation that captures concepts relevant to the task, but do so in an implicit way that hampers model interpretability. However, one could argue that such a representation is hidden in the neurons and can be made explicit by teaching the model to recognize semantically interpretable attributes that are present in the scene. We call such an intermediate layer a \emph{semantic bottleneck}. Once the attributes are learned, they can be re-combined to reach the final decision and provide both an accurate prediction and an explicit reasoning behind the CNN decision. In this paper, we look into semantic bottlenecks that capture context: we want attributes to be in groups of a few meaningful elements and participate jointly to the final decision. We use a two-layer semantic bottleneck that gathers attributes into interpretable, sparse groups, allowing them contribute differently to the final output depending on the context. We test our contextual semantic interpretable bottleneck (CSIB) on the task of landscape scenicness estimation and train the semantic interpretable bottleneck using an auxiliary database (SUN Attributes). Our model yields in predictions as accurate as a non-interpretable baseline when applied to a real-world test set of Flickr images, all while providing clear and interpretable explanations for each prediction.

The dynamics of eccentric accretion discs in superhump systems
Creators: name: Goodchild, Simon
name: Ogilvie, Gordon
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We have applied an eccentric accretion disc theory in simplified form to the case of an accretion disc in a binary system, where the disc contains the 3:1 Lindblad resonance. This is relevant to the case of superhumps in SU Ursae Majoris cataclysmic variables and other systems, where it is thought that this resonance leads to growth of eccentricity and a modulation in the light curve due to the interaction of a precessing eccentric disc with tidal stresses. A single differential equation is formulated which describes the propagation, resonant excitation and viscous damping of eccentricity. The theory is first worked out in the simple case of a narrow ring and leads to the conclusion that the eccentricity distribution is locally suppressed by the presence of the resonance, creating a dip in the eccentricity at the resonant radius. Application of this theory to the superhump case confirms this conclusion and produces a more accurate expression for the precession rate of the disc than has been previously accomplished with simple dynamical estimates.

description: High-power and narrow-linewidth laser light is a vital tool for atomic physics, being used for example in laser cooling and trapping and precision spectroscopy. Here we produce Watt-level laser radiation at 457.49 nm and 460.86 nm of respective relevance for the cooling transitions of cadmium and strontium atoms. This is achieved via the frequency doubling of a kHz-linewidth vertical-external-cavity surface-emitting laser (VECSEL), which is based on a novel gain chip design enabling lasing at > 2 W in the 915-928 nm region. Following an additional doubling stage, spectroscopy of the $^1S_0\to{}^1P_1$ cadmium transition at 228.89 nm is performed on an atomic beam, with all the transitions from all eight natural isotopes observed in a single continuous sweep of more than 4 GHz in the deep ultraviolet. The absolute value of the transition frequency of Cd-114 and the isotope shifts relative to this transition are determined, with values for some of these shifts provided for the first time

description: Plasmonic enhancement of fluorescence was investigated for its employment in sensing applications as well as in the design of low-cost fluorescence sensing devices. Two different plasmonic effects were considered, metal-enhanced fluorescence (MEF) and surface plasmon-coupled emission (SPCE). MEF occurs when the free space fluorescence condition is modified with sub-wavelength metallic nanoparticles resulting in an enhanced quantum yield and a decreased fluorescence lifetime. Another near-field plasmonic phenomenon is SPCE where the plasmon-coupling results in highly directional, polarized fluorescence emission. The first aspect of the research was to explore potential sensing applications incorporating SPCE. First, the high sensitivity of the phenomenon was examined through the detection of a monolayer of green fluorescent protein as evidenced by the visible emission ring. Secondly, a potential SPCE sensing application was investigated based on the fluorescence quenching of a monolayer of a ruthenium complex by oxygen. Due to the ultra-thin sensing layer, the observed response time was less than 0.5 seconds. In addition, despite the reduction in lifetime created by the metal film, lifetime-based sensing was also demonstrated in correlation with typical intensity-based measurements. Following the establishment of SPCE as a possible fluorescence sensing detection technique, investigations were performed leading to the development of a low-cost sensing device that incorporates SPCE for high sensitivity. First, low-cost excitation of SPCE via a light-emitting diode was observed. Next, solution-based silver deposition was studied as an alternative technique for the production of SPCE slides. The SPCE from these slides was similar to that observed from conventional vapor-deposited slides. Also, a SPCE detection scheme was designed and tested leading to a 500-fold enhancement of the free space signal with an almost 35-fold increase in the signal-to-noise ratio. In addition to SPCE, the benefits of MEF can also be used to improve current fluorescence-based assays. In this case, the enzyme-linked immunosorbent assay method for protein quantification was modified by the presence of sub-wavelength metallic nanoparticles resulting in faster assay times with similar sensitivity. In summary, the use of plasmonic structures to enhance fluorescence was demonstrated allowing for highly sensitive, rapid detection of analytes.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: In dynamical mean-field theory, the correlations between electrons are assumed to be purely local. The dual fermion approach provides a systematic way of adding non-local corrections to the dynamical mean-field theory starting point. Initial applications of this method were largely restricted to the single-orbital Hubbard model. Here, we present an implementation of second-order dual fermion for general multi-orbital systems and use this approach to investigate spatial correlations in SrVO$_3$. In addition, the approach is benchmarked in several exactly solvable small systems.
