description: Automatic Speech Recognition (ASR) engines are extremely susceptible to noise. There is an increasing prevalence of voice-assisted devices which need to recognize speech accurately in a variety of complex listening environments. These include the presence of
background noise, reverberation, and multiple talkers.
The human auditory system, on the other hand, is very good at understanding speech even in extremely challenging environments. It might therefore, be useful to use our knowledge of human hearing to develop techniques that lead to robust speech recognition. This entails applying techniques that have their basis in human auditory processing towards automatic speech recognition (ASR).
In this thesis, we discuss a number of techniques that address the problem of robust recognition of binaural signals in the presence of reverberation and multiple talkers since
they pose a significant problem in terms of ASR engine performance. The techniques discussed here roughly follow the manner in which the auditory system achieves noise
robustness. The fundamental idea behind all the techniques proposed is that sounds emanating from the same sound source exhibit some degree of coherence. We aim to use this property to achieve better isolation of the target signal leading to better speech recognition
accuracy. Three techniques are proposed. The Interaural Cross-correlation-basedWeighting (ICW) algorithm looks for coherence across sensors using signal envelopes in order to isolate signals coming from the same location. To reduce the effect of reverberation, steady-state suppression is applied as an initial step. The ICW algorithm combined with steady-state suppression leads to significant improvements in ASR accuracy. The Coherence-to-Diffuse Ratio-based Weighting (CDRW) algorithm uses a model-based technique to evaluate the ratio of coherent energy to diffuse energy in a given signal. This leads to significantly better performance in ASR. The third technique is the Cross-Correlation across Frequency (CCF) algorithm, which looks for coherence in frequency for signal separation. The CCF algorithm
also effectively smooths the signal. This algorithm has been tested in conjunction with steady-state suppression and ITD-based analysis. The CCF algorithm leads to improvements
in ASR especially in the presence of moderate to high reverberation when the system is trained on clean speech. All algorithmswere tested using DNN-based acoustical
models obtained with the Kaldi speech recognition toolkit, using both clean and multistyle training data.

description: Data Model for Scientific In-Depth Cataloging of Photographic Collections The paper presents a data model for cataloging photographs compliant with the Conceptual Reference Model (CIDOC CRM, ISO 21127:2014). It can be conceptually implemented in a wide variety of system environments.
 While a clear separation between information about a photographic image and the objects depicted on it is not or insufficiently feasible in widespread metadata standards such as Dublin Core, the CIDOC CRM provides the necessary framework to be able to address the photograph and the items depicted on it as separate but related entities. Moreover, it allows to make explicit the diverse relations to other entities and, in its granularity, to meet the requirements of a scientific in-depth indexing of photographic collections.
 The data model also relies on the Functional Requirements for Bibliographical Records (FRBR), which is well suited to describing the lineage relationships of the reproduction chain of negatives, prints and other possible derivatives, which is typical for photographs. The harmonization of both basic models is achieved in accordance with the Functional Requirements for Bibliographical Records Object-Oriented (FRBRoo).
 The paper includes an exemplary element set for cataloging photographic collections, specifies a designated set of core elements, and describes the cataloging priorities of an example collection documenting art and architecture.

Generalized von Smoluchowski model of reaction rates, with reacting particles and a mobile trap

description: We study diffusion-limited coalescence, A+AA, in one dimension, in the presence of a diffusing trap. The system may be regarded as a generalization of von Smoluchowski's model for reaction rates, in that: (a) it includes reactions between the particles surrounding the trap, and (b) the trap is mobile -- both considerations which render the model more physically relevant. As seen from the trap's frame of reference, the motion of the particles is highly correlated, because of the motion of the trap. An exact description of the long -time asymptotic limit is found using the IPDF method, and exploiting a "shielding" property of reversible coalescence that was discovered recently. In the case where the trap also acts as a source -- giving birth to particles -- the shielding property breaks down, but we find an "equivalence principle": Trapping and diffusion of the trap may be compensated by an appropriate rate of birth, such that the steady state of the system is identical with the equilibrium state in the absence of a trap.

description: Context. Polarized dust emission can be used as a probe for magnetic fields at different scales. In particular, the analysis of the relative orientation between the density structures and the magnetic field projected on the plane of the sky can provide information on the role of magnetic fields in shaping the structure of molecular clouds. Aims. The relative orientation has been investigated using different methods. Our goal is to explicitly compare two of them: the Rolling Hough Transform (RHT) and the gradient technique. Methods. We have applied the RHT method and the gradient technique to two regions, identified in surface brightness maps at 353 GHz generated via MHD simulations post-processed using radiative transfer modelling. For both methods we have derived the relative orientation between the magnetic field and the density structures, to which we have applied two different statistics, the histogram of relative orientation (HRO) statistic and the projected Rayleigh statistic (PRS). Results. The samples of pixels selected by each method are substantially different. When the methods are applied to the same pixel selection, the results in terms of relative orientation as a function of column density are consistent between each other. When each method is applied to its own pixel selection, the differences are apparent. In Region 1, the RHT method roughly reproduces the observed trend of the relative orientation becoming more perpendicular for increasing column density, while the gradient method, applied at the same resolution as RHT, gives the opposite trend, with the relative orientation moving towards a more parallel alignment. In Region 2, the situation is reversed. The inconsistent results, which are due to the different pixel selections operated by the methods and to the intrinsic differences between them, provide complementary valuable information. Abridged.

description: Critical slowing down of the relaxation of the order parameter is relevant both in early the universe and in ultrarelativistic heavy ion collisions. We study the relaxation rate of the order parameter in an O(N) scalar theory near the critical point to model the non-equilibrium dynamics of critical fluctuations near the chiral phase transition.A lowest order perturbative calculation (two loops in the coupling lambda) reveals the breakdown of perturbation theory for long-wavelength fluctuations in the critical region and the emergence of a hierarchy of scales with hard q>T, semisoft T >> q >> lambda T and soft lambda T>>q loop momenta which are widely separated for weak coupling. The non-perturbative resummation in the large N limit reveals the renormalization of the interaction and the crossover to an effective 3D-theory for soft momenta.The effective 3D coupling goes to the Wilson-Fisher 3D fixed point in the soft limit.The relaxation rate of the order parameter for wave vectors lambda T >>k>> k_{us} or near the critical temperature lambda T>>m_T>>k_{us} with the ultra soft scale k_{us} = [(lambda T)/(4pi)] exp[-(4pi/lambda)] is dominated by classical semisoft loop momentum leading to Gamma(k,T) = lambda T/(2 pi N). For wavectors k<< k_{us} the damping rate is dominated by hard loop momenta and given by Gamma(k,T)=4 pi T/[3N ln(T/k)]. Analogously, for homogeneous fluctuations in the ultracritical region m_T<

All Couplings of Minimal Six-dimensional Supergravity

description: We describe the complete coupling of $(1,0)$ six-dimensional supergravity to tensor, vector and hypermultiplets. The generalized Green-Schwarz mechanism implies that the resulting theory embodies factorized gauge and supersymmetry anomalies, to be disposed of by fermion loops. Consequently, the low-energy theory is determined by the Wess-Zumino consistency conditions, rather than by the requirement of supersymmetry. As already shown for the case without hypermultiplets, this procedure does not fix a quartic coupling for the gauginos. With respect to these previous results, the inclusion of charged hypermultiplets gives additional terms in the supersymmetry anomaly. We also consider the case in which abelian vectors are present. As in the absence of hypermultiplets, abelian vectors allow additional couplings. Finally, we apply the Pasti-Sorokin-Tonin prescription to this model.

description: We present an exact solution of a probabilistic cellular automaton for traffic with open boundary conditions, e.g. cars can enter and leave a part of a highway with certain probabilities. The model studied is the asymmetric exclusion process (ASEP) with {\it simultaneous} updating of all sites. It is equivalent to a special case ($v_{\rm max}=1$) of the Nagel-Schreckenberg model for highway traffic, which has found many applications in real-time traffic simulations. The simultaneous updating induces additional strong short range correlations compared to other updating schemes. The stationary state is written in terms of a matrix product solution. The corresponding algebra, which expresses a system-size recursion relation for the weights of the configurations, is quartic, in contrast to previous cases, in which the algebra is quadratic. We derive the phase diagram and compute various properties such as density profiles, two point functions and the fluctuations in the number of particles (cars) in the system. The current and the density profiles can be mapped onto the ASEP with other time discrete updating procedures. Through use of this mapping, our results also give new results for these models.

description: Local galaxies from the Sloan Digital Sky Survey are used to provide additional support for an evolutionary pathway in which AGN activity is associated with star-formation quenching. Composite, Seyfert 2 and LINER galaxies account for $\sim$60\% of all star-formation in massive galaxies ($M_\star > 10^{10.5} M_\odot$). Inclusion of these galaxies results in a "turnover" in the $SFR - M_\star$ relation for massive galaxies. Our analysis shows that bulge growth has already occurred in the most massive galaxies ($M_\star > 10^{10.5}$ $M_\odot$), and bulges continue to grow as galaxies quench and redden, $(g-r)$ = 0.5 $\rightarrow$ 0.75. Significant bulge growth is also occurring in low mass starburst galaxies ($M_\star < 10^{10.5} M_\odot$) at 0.5 dex above the "main sequence" (MS), where we find an increase in $B/T$ from 0.1 $\rightarrow$ 0.3 and bluer colours, $(g-r) < 0.25$ compared to low-mass galaxies on the MS.

description: We make a modified spin-wave description of the nuclear spin relaxation in Heisenberg alternating-spin chains with antiferromagnetic exchange coupling. In contrast with the conventional one-dimensional antiferromagnetic spin-wave theory, which is plagued with the divergence of the sublattice magnetization even in the ground state, the present spin-wave description is highly successful over a wide temperature range. The temperature dependence of the relaxation rate $T_1^{-1}$ significantly varies with the crystalline structure, exhibiting both ferromagnetic and antiferromagnetic aspects. $T_1^{-1}$ further shows a unique dependence on the applied field, which turns out an indirect observation of the quadratic dispersion relations.

description: The dependence of high-harmonic generation (HHG) on laser ellipticity is investigated using a modified ZnO model. In the driving of relatively weak field, we reproduce qualitatively the ellipticity dependence as observed in the HHG experiment of wurtzite ZnO. When increasing the field strength, the HHG shows an anomalous ellipticity dependence, similar to that observed experimentally in the single-crystal MgO. With the help of a semiclassical analysis, it is found that the key mechanism inducing the change of ellipticity dependence is the interplay between the dynamical Bloch oscillation and the anisotropic band structure. The dynamical Bloch oscillation contributes additional quantum paths, which are less sensitive to ellipticity. The anisotropic band-structure make the driving pulse with finite ellipticity be able to drive the pairs to the band positions with larger gap, which extends the harmonic cutoff. The combination of these two effects leads to the anomalous ellipticity dependence. The result reveals the importance of dynamical Bloch oscillations for the ellipticity dependence of HHG from bulk ZnO.

description: We report the discovered class of exact static solutions of several 4D Einstein-Maxwell-dilaton systems: string-induced, Liouville, trigonometric, polynomial, etc., for three basic topologies (spherical, hyperbolical and flat) being uniformly treated. In addition to the usual electric-magnetic duality this class obeys a certain extended duality between Maxwell-dilaton coupling and dilaton mass. Though major solutions we obtain are dyonic, the class also comprises interesting neutral models. As a by-product, we significantly succeded in resolving of the two important problems, one of which has been standing more than a decade (system with the string-inspired exponential Maxwell-dilaton coupling and non-vanishing dilaton mass) and another one - gravity coupled to massive neutral scalar field: generalized Liouville, Sin(h), Cos(h) - is about fifty years old. Finally, we demonstrate the full separability of the static EMD system and publicize the simple procedure of how to generate new integrability classes.

description: In this work we implement the Minimal Geometric Deformation decoupling method to obtain general static interior solutions for a BTZ vacuum from the most general isotropic solution in $2+1$ dimensions including the cosmological constant $Λ$. We obtain that the general solution can be generated only by the energy density of the original isotropic sector, so that this quantity plays the role of a generating function. Although as a particular example we study the static star with constant density, the method here developed can be easily applied to more complex situations described by other energy density profiles.

description: For analyzing the thermodynamical behavior of two well-known black holes such as RN-AdS black hole with global monopole and $f(R)$ black hole, we consider the higher order logarithmic corrected entropy. We develop various thermodynamical properties such as, entropy, specific heats, pressure, Gibb's and Helmhotz free energies for both black holes in the presence of corrected entropy. The versatile study on the stability of black holes is being made by using various frameworks such as the ratio of heat capacities ($γ$), grand canonical and canonical ensembles, and phase transition in view of higher order logarithmic corrected entropy. It is observed that both black holes exhibit more stability (locally as well as globally) for growing values of cosmological constant and higher order correction terms.

Novel enantioselective organocatalytic reactions to access promising scaffolds for medicinal chemistry and natural product synthesis via fluorinated intermediates
Creators: name: Rodriguez-Alvarado, Melanie
Publisher: name: No Publisher Supplied
Year: 2021

description: The demand for chiral synthetic compounds has led the field of asymmetric catalysis to discover, explore and develop new catalytic strategies to achieve pure optically active compounds. The Organocatalysis field, a division of asymmetric catalysis, is defined as the use of organic molecules to catalyze chemical transformations. This field has grown exponentially over the past decades. Discussed herein is use of chiral organic catalysts in the synthesis of both enantiopure Medicinal Drugs and complex Natural Product motifs. In Medicinal Drug synthesis, a selective introduction of a fluorine atom to the alpha position of an aldehyde via a double enamine organocascade using (L)-proline resulted in a gem-chlorofluoro stereogenic center. This fluorination was achieved using a mild, operationally simple, organocatalytic protocol allowing direct access to carbon-fluorine stereocenter formation. The synthesized gem-chlorofluoro stereocenters were further utilized as fluorinated intermediates in the synthesis of fluorinated LpxC inhibitors against Gram-Negative bacteria. The synthesized fluorinated enantiopure LpxC inhibitors were tested for antibacterial activity and showed micromolar activity of ≤12.5 μg/mL against Pseudomonas Aeruginosa, one of the pathogens with growing multidrug resistance. Furthermore, new strategies for the asymmetric synthesis of optically active synthons for alkaloid synthesis were studied. It is known that ylides derived from quaternary ammonium salts can undergo competing [2,3]- and [1,2]- (i.e., Stevens) rearrangements, and diastereoselective versions of Stevens [1,2]-rearrangements have been exploited in synthesis to establish complex polycyclic backbones of alkaloid scaffolds. However, these methods require pre-installed stereogenic centers and enantiopure ammonium ylide starting materials, which are not trivial to access. Moreover, while the first examples of catalytic asymmetric [2,3]- and formal [2,3]-rearrangements of ammonium ylides have been recently reported by the Tambar and Smith groups, the corresponding catalytic asymmetric [1,2]-rearrangement remains elusive. Inspired by the works of Tambar and Smith and using insight from a very recent report by Singleton et. al. regarding how to bias these two competing reactions, in combination with our own rational design, efforts to develop the first catalytic asymmetric [1,2]-Stevens rearrangement of an ylide formed from a quaternary ammonium salt are reported.

The labor gap between women and men is persistent. The differences in remuneration and leadership externalize structural orders of a patriarchal court that govern the development of each union; always in coordination with his public and private environment. Scientific work is no exception. This article refers to the minority and segregation status of academics attached to Mexican universities, despite the ground gained gradually in inclusion and equity. The subject of theoretical recognition was studied in depth, which today is disputed in virtual space; to do this, we reviewed the data from three international repositories, specialized in scientific literature. The exploration revealed that the presence and hierarchical position of the researcher's women are even more opaque in internet than in the physical-institutional space. From the above, the use of digital tools is called as a way to improve dialogue and notoriety in the trade. La brecha laboral entre mujeres y hombres es persistente. Las diferencias en remuneraciones y liderazgos exteriorizan órdenes estructurales de corte patriarcal que rigen el desenvolvimiento de cada gremio; siempre en sintonía con su entorno público y privado. El trabajo científico no es la excepción. Este artículo remite a la condición de minoría y segregación de académicas adscritas a universidades mexicanas, pese al terreno ganado –a paso lento– en inclusión y equidad. Se profundizó en el rubro del reconocimiento teórico, que hoy se disputa en el espacio virtual; para ello recurrimos a los datos de tres repositorios internacionales especializados en literatura científica. La exploración reveló que la presencia y la posición jerárquica de las investigadoras, son aún más opacas en internet que en el espacio físico-institucional. De lo anterior, se llama al empleo de herramientas digitales como una vía para mejorar la interlocución y notoriedad en el oficio.

description: 1. Terbinafine (TBF), a common antifungal agent, has been associated with rare incidences of hepatotoxicity. It is hypothesized that bioactivation of TBF to reactive intermediates and subsequent binding to critical cellular proteins may contribute to this toxicity. In the present study, we have characterized the bioactivation pathways of TBF extensively in human, mouse, monkey, dog and rat liver microsomes and hepatocytes. 2. A total of twenty glutathione conjugates of TBF were identified in hepatocytes; thirteen of these conjugates were also detected in liver microsomes. To the best of our knowledge, only two of these conjugates have been reported previously. The conjugates were categorized into three groups based on their mechanism of formation: (a) alkene/alkyne oxidation followed by glutathione conjugation, with or without N-demethylation, (b) arene oxidation followed by glutathione conjugation, with or without N-demethylation, and (c) N-dealkylation followed by glutathione conjugation of the allylic aldehyde, alcohol and acid intermediates. 3. Differences were observed across species in the contributions of these pathways toward overall metabolic turnover. We conclude that, in addition to the glutathione conjugates known to form by Michael addition to the allylic aldehyde, there are other pathways involving the formation of arene oxides and alkene/alkyne epoxides that may be relevant to the discussion of TBF-mediated idiosyncratic drug reactions.

description: A green and cost-effective Pummerer-type rearrangement between readily accessible carboxylic acids and DMSO has been achieved under metal-free conditions in satisfactory to excellent yields. The transformation for the synthesis of valuable methylthiomethyl esters is shown to be a convenient strategy for various (hetero)aromatic acids, α,β-unsaturated carboxylic acids and saturated alkyl carboxylic acids with good functional group tolerance.

description: We report inelastic light scattering measurements of dispersive spin and charge density excitations in dilute 2D electron systems reaching densities less than 10^{10} cm^{-2}. In the quantum Hall state at nu=2, roton critical points in the spin inter--Landau level mode show a pronounced softening as r_s is increased. Instead of a soft mode instability predicted by Hartree--Fock calculations for r_s ~ 3.3, we find evidence of multiple rotons in the dispersion of the softening spin excitations. Extrapolation of the data indicates the possibility of an instability for r_s >~ 11.

description: Infrared divergences have long been heralded to cancel in sufficiently inclusive cross-sections, according to the famous Kinoshita-Lee-Nauenberg theorem which mandates an initial and final state sum. While well-motivated, this theorem is much weaker than necessary: for finiteness, one need only sum over initial $\textit{or}$ final states. Moreover, the cancellation generically requires the inclusion of the forward scattering process. We provide a number of examples showing the importance of this revised understanding: in $e^+e^- \to Z$ at next-to-leading order, one can sum over certain initial and final states with an arbitrary number of extra photons, or only over final states with a finite number of photons, if forward scattering is included. For Compton scattering, infrared finiteness requires the indistinguishability of hard forward-scattered electrons and photons. This implies that in addition to experimental limits on the energy and angular resolution, there must also be an experimental limit on the momentum at which electric charge can be observed. Similar considerations are required to explain why the rate for $γγ$ to scatter into photons alone is infrared divergent but the rate for $γγ$ to scatter into photons or charged particles is finite. This new understanding sheds light on the importance of including degenerate initial states in physical predictions, the relevance of disconnected Feynman diagrams, the importance of dressing initial or final-state charged particles, and the quest to properly define the $S$ matrix.

description: Learning to write successful grant applications takes significant time and effort. This paper presents knowledge, expertise, and strategies from experienced grant applicants and grant officers across several disciplines to support early career scholars and first-time grant writers, with particular guidance for interdisciplinary collaboration. Many Agricultural and Applied Economists are invited to participate in interdisciplinary grant applications. It is important to fully understand the types of projects, nature of collaboration, co-investigators’ characteristics, expected contributions, anticipated benefits, and valuation of collaborative research by one’s peers before initiating new opportunities. Leading and participating in interdisciplinary teams also requires mentorship, patience, professionalism, and excellent communication beyond the scientific merits. This paper shares practical insights to guide scholars through the grant-writing processes beginning with nurturing a mindset, preparing for a consistent work ethic, actively seeking advice, identifying targeted programs, matching a programs’ priorities, a step-by-step framework for team creation and management, effectively managing time and pressure, and transforming failure into success.

description: Classes in microeconomics typically use cubic cost functions because they can exhibit marginal costs that fall as output increases to some efficient level, and then rise thereafter. Cubic cost functions embody economies of scale, making it easy to illustrate that concept with quadratic average cost curves. However, designing problems with cubic cost functions is harder than it looks because wellbehaved functions must meet several mathematical and economic restrictions. Yet as instructors develop more online assignments and exam questions, they face the need to produce varied problems that support the same learning objectives. This article explains the restrictions needed to generate well-behaved cubic cost functions. It proceeds to show how to generate random parameters for wellbehaved cubic cost functions for problems that meet common student learning objectives. An associated workbook contains the algorithms described here.
