description: While ubiquitous in supersymmetric and string theory models, inflationary scenarios near an inflection point in the scalar potential generically require a severe fine-tuning of a priori unrelated supersymmetry breaking effects. We show that this can be significantly alleviated by the inclusion of dissipative effects that damp the inflaton's motion and produce a nearly-thermal radiation bath. We focus on the case where the slow-rolling inflaton directly excites heavy virtual modes that then decay into light degrees of freedom, although our main qualitative results should apply in other regimes. Furthermore, our analysis shows that the minimum amount of dissipation required to keep the temperature of the radiation bath above the Hubble rate during inflation is largely independent of the degree of flatness of the potential, although it depends on the field value at the inflection point. We then discuss the relevance of this result to warm inflation model building.

description: Time reversal mirrors work perfectly only for lossless wave propagation. Here, the performance of time-reversal mirrors is quantitatively defined, and the adverse effect of dissipation on their performance is investigated. An application of the technique of exponential amplification is proposed to overcome the effect of dissipation in the case of uniform loss distributions, and, to some extent, in the case of non-uniform loss distributions. A numerical model of a star graph was employed to test the applicability of this technique on realizations with various random spatial distributions of loss. A subset of the numerical results are also verified by experimental results from an electromagnetic time-reversal mirror. The exponential amplification technique should improve the performance of emerging technologies based on time-reversed wave propagation such as directed communication and wireless power transfer.

description: Purpose: Microaggressions and how they affect underrepresented college students have been frequently documented. However, there is a lack of literature on the experiences of underrepresented communication sciences and disorders (CSD) students. The purpose of this study is to understand how underrepresented post baccalaureate, undergraduate, and graduate students in CSD experience microaggressions in their academic programs.Method: A 19-item electronic survey was developed by American Speech-Language-Hearing Association’s Multicultural Issues Board and distributed via multiple online platforms. A diverse group of 155 underrepresented CSD students completed the survey. A multistage qualitative thematic analysis was used to analyze students’ experiences.Results: Students (64.51%) who completed the survey have experienced microaggressions in their academic programs. Prominent themes of students’ descriptions of microaggressions included feelings of otherness, damaging generalization, maltreatment from faculty, and maltreatment from peers. Students reported various responses to microaggressions including identity management strategies, disengaging, and working hard to exceed expectations and to prove themselves.Conclusions: This study illustrates the ways that underrepresented CSD students experience symbolic violence from clients, peers, and faculty. It has implications for the need to cultivate more inclusive learning and social environments in CSD programs. Further research is needed to explore the ramifications of microaggressions and ways to effectively reduce and eventually eradicate them.

title: Development of mode of action tools using lysyl-tRNA synthetase to support Cryptosporidium drug discovery

description: Cryptosporidium is a major cause of diarrhoeal disease particularly in young children, where it accounted for nearly 50,000 deaths in 2016. There are currently no effective treatments for cryptosporidiosis in the patient groups where the disease burden is felt most harshly. This unmet need has led to the development of several promising new therapeutics, including those which target lysyl-tRNA synthetase (KRS). Alongside the development of these novel therapeutics, it is vital that tools are available to identify and characterise the targets of these drugs. This ensures that the Cryptosporidium drug discovery pipeline is populated by compounds acting on known targets that are essential for parasite survival. To achieve this, I aimed to leverage the known target of KRS and its inhibitor, Compound 5, to establish mode of action tools that support Cryptosporidium drug discovery.
By probing the basic biology of this target, I found it to be expressed in all life cycle stages but particularly highly expressed in asexual stages. Conditional knockdown of KRS prevented parasite shedding in a mouse model of infection and inhibition of KRS with Compound 5 caused asexual parasite death. I then used this KRS-Compound 5 drug-target pair to optimise and establish thermal proteome profiling (TPP) for Cryptosporidium. This establishes TPP as the first target blind method of drug target identification in Cryptosporidium.
I then used genetic approaches to generate independent strains which overexpress KRS or express KRS with a single amino acid substitution. In each case, these modifications generated resistance to Compound 5. I then combined these mechanisms of resistance to generate a novel selection marker, KRSR. This selection marker can be used in conjunction with the established NeoR to generate and select for Cryptosporidium genetic crosses, greatly expanding Cryptosporidium genetic engineering

description: In this letter, we note that the denoising performance of Non-Local Means (NLM) at large noise levels can be improved by replacing the mean by the Euclidean median. We call this new denoising algorithm the Non-Local Euclidean Medians (NLEM). At the heart of NLEM is the observation that the median is more robust to outliers than the mean. In particular, we provide a simple geometric insight that explains why NLEM performs better than NLM in the vicinity of edges, particularly at large noise levels. NLEM can be efficiently implemented using iteratively reweighted least squares, and its computational complexity is comparable to that of NLM. We provide some preliminary results to study the proposed algorithm and to compare it with NLM.

description: Non-spherical systems described by MOND theories of modified gravity arising from generalizations of the Poisson equations are affected by a MONDian extra-quadrupolar potential ϕ_M even if they are isolated and they are in deep Newtonian regime. In general MOND theories quickly approaching Newtonian dynamics for accelerations beyond A_0, ϕ_M is proportional to a multiplicative scaling coefficient α\sim 1, while in MOND models becoming Newtonian beyond κA_0, κ>> 1, it is enhanced by κ^2. We analytically work out some orbital effects due to ϕ_M in the framework of QUMOND, and compare them with the latest observational determinations of Solar System's planetary dynamics, exoplanets and double lined spectroscopic binary stars. The current admissible range for the anomalous perihelion precession of Saturn yields |κ| <= 3.5 x 10^3, while the radial velocity of αCen AB allows to infer |κ|<= 6.2 x 10^4 (A) and |κ|<= 4.2 x 10^4 (B). In evaluating such preliminary constraints it must be recalled that QUMOND is not the nonrelativistic limit of TeVeS.

description: Restoration is a long-standing concept in ecology and guiding principle for many environmental institutions including the European Union's proposed Nature Restoration Law. The terms ‘restoration’ and the newer term of ‘Nature-based Solutions’ are both commonly used, sometimes interchangeably. However these concepts are not identical and understanding these differences might help us find ways to tackle the nature and climate crises more effectively. We examine the implications of the different concepts, to help shape and prioritise future action.

description: If $E$ is an elliptic curve defined over $\mathbb Q$ and $p$ is a prime of good reduction for $E$, let $E(\mathbb F_p)$ denote the set of points on the reduced curve modulo $p$. Define an arithmetic function $M_E(N)$ by setting $M_E(N):= \#\{p: \#E(\mathbb F_p)= N\}$. Recently, David and the third author studied the average of $M_E(N)$ over certain "boxes" of elliptic curves $E$. Assuming a plausible conjecture about primes in short intervals, they showed the following: for odd $N$, the average of $M_E(N)$ over a box with sufficiently large sides is $\sim \frac{K^{\ast}(N)}{\log{N}}$ for an explicitly-given function $K^{\ast}(N)$. The function $K^{\ast}(N)$ is somewhat peculiar: defined as a product over the primes dividing $N$, it resembles a multiplicative function at first glance. But further inspection reveals that it is not, and so one cannot directly investigate its properties by the usual tools of multiplicative number theory. In this paper, we overcome these difficulties and prove a number of statistical results about $K^{\ast}(N)$. For example, we determine the mean value of $K^{\ast}(N)$ over all $N$, odd $N$ and prime $N$, and we show that $K^{\ast}(N)$ has a distribution function. We also explain how our results relate to existing theorems and conjectures on the multiplicative properties of $\# E(\mathbb F_p)$, such as Koblitz's conjecture.

Baryon Masses and Axial Couplings in the Combined 1/Nc and Chiral Expansions

description: The effective theory for baryons with combined 1/Nc and chiral expansions is analyzed for non-strange baryons. Results for baryon masses and axial couplings are obtained in the small scale expansion, to be coined as the ξ-expansion, in which the 1/Nc and the low energy power countings are linked according to 1/Nc=O(ξ)=O(p). Masses and axial couplings are analyzed to O(ξ^3) and O(ξ^2) respectively, which correspond to next-to-next to leading order evaluations, and require one-loop contributions in the effective theory. The role of the spin-flavor approximate symmetry in baryons, consequence of the large Nc limit, is manifested in the physical world with Nc=3 in a significant way, as the analysis of its breaking in the masses and the axial couplings shows. Applications to the recent lattice QCD results on baryon masses and the nucleon's axial coupling are presented. It is shown that those results are naturally described within the effective theory at the order considered in the ξ-expansion.

description: We define the notion of a spanning tree generating function (STGF) $\sum a_n z^n$, which gives the spanning tree constant when evaluated at $z=1,$ and gives the lattice Green function (LGF) when differentiated. By making use of known results for logarithmic Mahler measures of certain Laurent polynomials, and proving new results, we express the STGFs as hypergeometric functions for all regular two and three dimensional lattices (and one higher-dimensional lattice). This gives closed form expressions for the spanning tree constants for all such lattices, which were previously largely unknown in all but one three-dimensional case. We show for all lattices that these can also be represented as Dirichlet $L$-series. Making the connection between spanning tree generating functions and lattice Green functions produces integral identities and hypergeometric connections, some of which appear to be new.

description: The numerical investigation of wave propagation in the asymptotic domain of Kerr spacetime has only recently been possible thanks to the construction of suitable hyperboloidal coordinates. The asymptotics revealed an apparent puzzle in the decay rates of scalar fields: the late-time rates seemed to depend on whether finite distance observers are in the strong field domain or far away from the rotating black hole, an apparent phenomenon dubbed "splitting". We discuss far-field "splitting" in the full field and near-horizon "splitting" in certain projected modes using horizon-penetrating, hyperboloidal coordinates. For either case we propose an explanation to the cause of the "splitting" behavior, and we determine uniquely decay rates that previous studies found to be ambiguous or immeasurable. The far-field "splitting" is explained by competition between projected modes. The near-horizon "splitting" is due to excitation of lower multipole modes that back excite the multipole mode for which "splitting" is observed. In both cases "splitting" is an intermediate effect, such that asymptotically in time strong field rates are valid at all finite distances. At any finite time, however, there are three domains with different decay rates whose boundaries move outwards during evolution. We then propose a formula for the decay rate of tails that takes into account the inter--mode excitation effect that we study.

description: In recent years there has been a surge of interest in the statistics of record-breaking events in stochastic processes. Along with that, many new and interesting applications of the theory of records were discovered and explored. The record statistics of uncorrelated random variables sampled from time-dependent distributions was studied extensively. The findings were applied in various areas to model and explain record-breaking events in observational data. Particularly interesting and fruitful was the study of record-breaking temperatures and their connection with global warming, but also records in sports, biology and some areas in physics were considered in the last years. Similarly, researchers have recently started to understand the record statistics of correlated processes such as random walks, which can be helpful to model record events in financial time series. This review is an attempt to summarize and evaluate the progress that was made in the field of record statistics throughout the last years.

description: We present optical photometry and spectroscopy of five type Ia supernovae discovered by the Nearby Supernova Factory selected to be spectroscopic analogues of the candidate super-Chandrasekhar-mass events SN 2003fg and SN 2007if. Their spectra are characterized by hot, highly ionized photospheres near maximum light, for which SN 1991T supplies the best phase coverage among available close spectral templates. Like SN 2007if, these supernovae are overluminous (-19.5 < M_V < -20) and the velocity of the Si II 6355 absorption minimum is consistent with being constant in time from phases as early as a week before, and up to two weeks after, $B$-band maximum light. We interpret the velocity plateaus as evidence for a reverse-shock shell in the ejecta formed by interaction at early times with a compact envelope of surrounding material, as might be expected for SNe resulting from the mergers of two white dwarfs. We use the bolometric light curves and line velocity evolution of these SNe to estimate important parameters of the progenitor systems, including nickel-56 mass, total progenitor mass, and masses of shells and surrounding carbon/oxygen envelopes. We find that the reconstructed total progenitor mass distribution of the events (including SN 2007if) is bounded from below by the Chandrasekhar mass, with SN 2007if being the most massive. We discuss the relationship of these events to the emerging class of super-Chandrasekhar-mass SNe Ia, estimate the relative rates, compare the mass distribution to that expected for double-degenerate SN Ia progenitors from population synthesis, and consider implications for future cosmological Hubble diagrams.

In particular, we introduce a cavity to describe the thermodynamics at a finite isothermal surface on general ground and to get a well-defined thermodynamics. We show that there exists a locally stable small black hole which tunnels to the hot flat space below the critical temperature and to the large black hole above the critical temperature. Moreover, it turns out that the remnant decays into the vacuum through a quantum tunneling.

description: We present a modified bond-valence model of PbTiO$_3$ based on the principles of bond-valence and bond-valence vector conservation. The relationship between the bond-valence model and the bond-order potential is derived analytically in the framework of a tight-binding model. A new energy term, bond-valence vector energy, is introduced into the atomistic model and the potential parameters are re-optimized. The new model potential can be applied both to canonical ensemble ($NVT$) and isobaric-isothermal ensemble ($NPT$) molecular dynamics (MD) simulations. This model reproduces the experimental phase transition in $NVT$ MD simulations and also exhibits the experimental sequence of temperature-driven and pressure-driven phase transitions in $NPT$ simulations. We expect that this improved bond-valence model can be applied to a broad range of inorganic materials.

description: One believes there is huge amount of Dark Matter particles in our Galaxy which manifest themselves only gravitationally. There is a big challenge to prove their existence in a laboratory experiment. To this end it is not sufficient to fight only for the best exclusion curve, one has to see an annual recoil spectrum modulation --- the only available positive direct dark matter detection signature. A necessity to measure the recoil spectra is stressed.

description: In this paper one examine analytical solutions for flat and non-flat universes composed by four components namely hot matter (ultra-relativistic), warm matter (relativistic), cold matter (non-relativistic) and cosmological constant. The warm matter is treated as a reduced relativistic gas and the other three components are treated in the usual way. The solutions achieved contains one, two or three components of which one component is of warm matter type. A solution involving all the four components was not found.

description: Purpose: The purpose of this study was to investigate engagement in collaborative research (team science) and perceptions of related knowledge and skills to inform personnel preparation and workforce development efforts.Method: A questionnaire was used to solicit information about the team science–related experiences of 220 doctoral students, faculty, and research scientists in speech-pathology and audiology. Additionally, the questionnaire surveyed participants’ perceptions of readiness, benefits, and challenges to team science.Results: Results demonstrated low percentages of respondents had received training in collaborative research (17%), and those with training were more likely to engage in cross-disciplinary collaborative research. Group differences were found with female researchers reporting lower psychological safety than male researchers. The most frequently cited advantages of team science included diverse perspectives, collective expertise, innovative ideas, and productivity. Conversely, common challenges included time constraints, finding collaborators, and differing expectations.Implications: Because this study yielded group difference in psychological safety between groups that differed in gender and position, results suggest additional efforts may be necessary to ensure that imbalances in the power structure of members are not allowed to dissuade members from actively contributing to team activities. Additional training opportunities in team science could support the degree to which professionals in communication science and disorders engage in collaborative research.

description: We propose a class of projected BCS wave functions and derive their parent spin Hamiltonians. These wave functions can be formulated as infinite Matrix Product States constructed by chiral correlators of Majorana fermions. In 1D, the spin Hamiltonians can be viewed as SO(n) generalizations of Haldane-Shastry models. We numerically compute the spin-spin correlation functions and Renyi entropies for n=5 and 6. Together with the results for n=3 and 4, we conclude that these states are critical and their low-energy effective theory is the SO(n)_1 Wess-Zumino-Witten model. In 2D, we show that the projected BCS states are chiral spin liquids, which support non-Abelian anyons for odd n and Abelian anyons for even n.

description: We scrutinize the enhanced superconducting performance of melt quench Bismuth based Bi2Sr2CaCu2O8 (Bi-2212) superconductor. The superconducting properties of melt quenched Bi-2212 (Bi2212-MQ) sample are compared with non-melted Bi2212-NM and Bi1.4Pb0.6Sr2Ca2Cu3O10 (Bi-2223). Crystal structure and morphology of the samples are studied using X-ray diffraction and Scanning Electron Microscopy (SEM) techniques. The high field (14T) magneto-transport and DC/AC magnetic susceptibility techniques are extensively used to study the superconducting properties of the investigated samples. The superconducting critical temperature (Tc) and upper critical field (Hc2) as well as thermally activated flux flow (TAFF) activation energy are estimated from the magneto-resistive [R(T)H] measurements. Both DC magnetization and amplitude dependent AC susceptibility measurements are used to determine the field and temperature dependence of critical current density (Jc) for studied samples. On the other hand, the frequency dependent AC susceptibility is used for estimating flux creep activation energy. It is found that melt quenching significantly enhances the superconducting properties of granular Bi-2212 superconductor. The results are interpreted in terms of better alignment and inter-connectivity of the grains along with reduction of grain boundaries for Bi2212-MQ sample.

description: The experimental determination of the properties of the newly discovered boson at the Large Hadron Collider is currently the most crucial task in high energy physics. We show how information about the spin, parity, and, more generally, the tensor structure of the boson couplings can be obtained by studying angular and mass distributions of events in which the resonance decays to pairs of gauge bosons, $ZZ, WW$, and $γγ$. A complete Monte Carlo simulation of the process $pp \to X \to VV \to 4f$ is performed and verified by comparing it to an analytic calculation of the decay amplitudes $X \to VV \to 4f$. Our studies account for all spin correlations and include general couplings of a spin $J=0,1,2$ resonance to Standard Model particles. We also discuss how to use angular and mass distributions of the resonance decay products for optimal background rejection. It is shown that by the end of the 8 TeV run of the LHC, it might be possible to separate extreme hypotheses of the spin and parity of the new boson with a confidence level of 99% or better for a wide range of models. We briefly discuss the feasibility of testing scenarios where the resonances is not a parity eigenstate.

description: If a real symmetric matrix of linear forms is positive definite at some point, then its determinant is a hyperbolic hypersurface. In 2007, Helton and Vinnikov proved a converse in three variables, namely that every hyperbolic plane curve has a definite real symmetric determinantal representation. The goal of this paper is to give a more concrete proof of a slightly weaker statement. Here we show that every hyperbolic plane curve has a definite determinantal representation with Hermitian matrices. We do this by relating the definiteness of a matrix to the real topology of its minors and extending a construction of Dixon from 1902. Like Helton and Vinnikov's theorem, this implies that every hyperbolic region in the plane is defined by a linear matrix inequality.

A topological extension of GR: Black holes induce dark energy

description: A topological extension of general relativity is presented. The superposition principle of quantum mechanics, as formulated by the Feynman path integral, is taken as a starting point. It is argued that the trajectories that enter this path integral are distinct, despite any quantum uncertainty in geometry, and thus that space-time topology is multiply connected. Specifically, space-time at the Planck scale consists of a lattice of three-tori that facilitates many distinct paths for particles to travel along. To add gravity, mini black holes are attached to this lattice. These mini black holes represent Wheeler's quantum foam and result from the fact that GR is not conformally invariant. The stable creation of such mini black holes is found to be caused by the existence of macroscopic (so long-lived) black holes. This connection, by which macroscopic black holes induce mini black holes, is a topological expression of Mach's principle. The proposed topological extension of GR can be tested because, if correct, the dark energy density of the universe should be linearly proportional to the total number of macroscopic black holes in the universe at any time. This prediction, although strange, agrees with current astrophysical observations.

Solution of electric-field-driven tight-binding lattice in contact with fermion reservoir

description: Electrons in tight-binding lattice driven by DC electric field dissipate their energy through on-site fermionic thermostats. Due to the translational invariance in the transport direction, the problem can be block-diagonalized. We solve this time-dependent quadratic problem and demonstrate that the problem has an oscillatory steady-state. The steady-state occupation number shows that the Fermi surface disappears for any damping from the thermostats and any finite electric field. Despite the lack of momentum scattering, the conductivity takes the same form as the semi-classical Ohmic expression from the relaxation-time approximation.

description: The goal of subversive humor about sex and gender is to challenge sexist beliefs and to subvert the traditional hierarchy of gender roles. However, because of the sensitive nature of the topic, this type of subversive humor can be misinterpreted as disparaging. This study sought to determine whether the a) perceived gender of the joke teller has an effect on the perception of disparaging and subversive humor and b) participants’ level of hostile sexism and the tendency to perceive gender prejudice would influence these reactions. A matched guise experiment featuring digitally altered recordings of subversive and disparaging jokes about gender was conducted with 238 participants recruited via MTurk. The results suggest that participants high in hostile sexism were more likely to enjoy disparaging humor against women, misinterpret subversive humor as disparaging, and rate male speakers as more likeable and less sexist than female speakers. Participants with higher level of stigma consciousness (SC) were more likely to enjoy both disparaging and subversive humor than those with lower levels of SC. Female participants rated female speakers as more likeable and less sexist, but male participants rated male and female speakers equally. Speakers who targeted their own ingroup were not viewed as more likeable than speakers who targeted the outgroup, but they were viewed as less sexist. There were no significant differences in ratings of joke funniness, joke offensiveness, speaker likeability, or speaker sexism between disparaging and subversive jokes, suggesting that listeners did not draw clear distinctions between the two types of humor. Furthermore, subversive humor was more likely to be misunderstood as disparaging than the other way around. Finally, jokes delivered by a male speaker were more likely to be labeled as disparaging while jokes delivered by a female speaker were more likely to be labeled as subversive. Results were interpreted in light of previous research findings and the study’s contributions, limitations, and possible future directions are discussed.
