Insight into Two-Dimensional Borophene: Five-Center Bond and Phonon-Mediated Superconductivity

description: We report a previously unknown monolayer borophene allotrope and we call it super-B with a flat structure based on the ab initio calculations. It has good thermal, dynamical, and mechanical stability compared with many other typical borophenes. We find that super-B has a fascinating chemical bond environment consisting of standard sp, sp2 hybridizations, and delocalized five-center three-electron $π$ bond, called $π$(5c-3e). This particular electronic structure plays a pivotal role in stabilizing the super-B chemically. By extra doping, super-B can be transformed into a Dirac material from pristine metal. Like graphene, it can also sustain tensile strain smaller than 24%, indicating superior flexibility. Moreover, due to the small atomic mass and large density of states at the Fermi level, super-B has the highest critical temperature Tc of 25.3 K in single-element superconductors at ambient conditions. We attribute this high Tc of super-B to the giant anharmonicity of two linear acoustic phonon branches and an unusually low optic phonon mode. These predictions provide new insight into the chemical nature of low dimensional boron nanostructures and highlight the potential applications of designing flexible devices and high Tc superconductors.

description: We determine an asymptotic expression of the blow-up time t_coll for self-gravitating Brownian particles or bacterial populations (chemotaxis) close to the critical point. We show that t_coll=t_{*}(eta-eta_c)^{-1/2} with t_{*}=0.91767702..., where eta represents the inverse temperature (for Brownian particles) or the mass (for bacterial colonies), and eta_c is the critical value of eta above which the system blows up. This result is in perfect agreement with the numerical solution of the Smoluchowski-Poisson system. We also determine the asymptotic expression of the relaxation time close but above the critical temperature and derive a large time asymptotic expansion for the density profile exactly at the critical point.
title: Navigating Uncertainty in Tax Strategy Surrounding the Tax Cuts and Jobs Act Sunset
Creators: name: Smith, Tate
Publisher: name: Utah State University
Year: 2024

description: Throughout history, taxpayers have relied on tax strategies to reduce the proportion of income that is deemed taxable by the government. Today's tax environment is no exception, and with the changes surrounding the Tax Cuts and Jobs Act (TCJA) Sunset, taxpayers need to prepare their tax plans. In 2025, much of the current tax legislation for individual taxpayers will potentially revert to the pre-TCJA legislation. Preparing a strategy during this time period will be difficult because when the current legislation sunsets in 2025 many of the legislation changes will depend on which political party controls the presidency.
This paper seeks to identify the best strategy that taxpayers can utilize to minimize their tax liability despite the uncertainty surrounding the 2025 deadline, by looking at historical strategies, pre-TCJA legislation strategies, and current strategies. By understanding these strategies, taxpayers can come closer to understanding their ideal strategy for the sunset. The research finds two tax plans can be created that are specific to the political party of the new president, Democrat or Republican. If taxpayers feel they know which party will win the election, some tax strategies can be implemented now. Otherwise, this research offers a third suggestion that is applicable, but not as tax efficient, regardless of which political party controls the presidency. However, this research cannot recommend a definitive best course of action until after the presidential election, as government elections will ultimately determine the legislation following the sunset.

description: We present an analysis of 16 state-of-the-art MT systems on German-English based on a linguistically-motivated test suite. The test suite has been devised manually by a team of language professionals in order to cover a broad variety of linguistic phenomena that MT often fails to translate properly. It contains 5,000 test sentences covering 106 linguistic phenomena in 14 categories, with an increased focus on verb tenses, aspects and moods. The MT outputs are evaluated in a semi-automatic way through regular expressions that focus only on the part of the sentence that is relevant to each phenomenon. Through our analysis, we are able to compare systems based on their performance on these categories. Additionally, we reveal strengths and weaknesses of particular systems and we identify grammatical phenomena where the overall performance of MT is relatively low.

description: Quantum vacua are constructed for a time-symmetric cosmology describing closed string tachyon condensation in two-dimensional string theory. Due to the Euclidean periodicity of the solution, and despite its time dependence, we are able to construct thermal states at discrete values of the temperature. The asymptotic thermal Green functions and stress energy tensor are computed and found to have an intriguing resemblance to those in the Hartle-Hawking vacuum of a black hole.

description: We discuss the possibility that the recent detection of 511 keV gamma-rays from the galactic bulge, as observed by INTEGRAL, is a consequence of low mass (~MeV) particle dark matter annihilations. We discuss the type of halo profile favored by the observations as well as the size of the annihilation cross section needed to account for the signal. We find that such a scenario is consistent with the observed dark matter relic density and other constraints from astrophysics and particle physics.

description: The presence of a dynamical scalar field in the early universe could significantly affect the `freeze-out' time of particle species. In particular, it was recently shown that an enhancement of the relic abundance of neutralinos can be produced in this way. We examine under which conditions this primordial scalar field could be identified with the Quintessence scalar and find, through concrete examples, that modifications to the standard paradigm are necessary. We discuss two possible cases: the presence of more scalars and the switching on of an interaction.

The species in this cluster is characterized by having genitalia with a granulose median keel in low position, almost at level with the dorsum of segment X. Unique characters are presence of apicodorsal corners of segment X developed into a long, tapering, upcurving processes; and presence of an almost filled intersegmental depression. The apicodorsal setose process is very short, or reduced, into a setose area located basally on segment X. Furthermore, the coxopodites strongly exceeding the body of segment X, and lacking apicoventral setose lobes. The harpagones are broad at basis and very slender distally.

description: Coupling between electronic and mechanical degrees of freedom in a single electron shuttle system can cause a mechanical instability leading to shuttle transport of electrons between external leads. We predict that the resulting low frequency current noise can be enhanced due to amplitude fluctuations of the shuttle oscillations. Moreover, at the onset of mechanical instability a pronounced peak in the low frequency noise is expected.

description: By means of interferometic 21-cm observations and a 3D kinematic modeling technique, we study the gas kinematics of six HI-rich ultra-diffuse galaxies (UDGs). We derive robust circular velocities and baryonic masses, that allow us to study the position of our UDGs with respect to the baryonic Tully-Fisher relation (BTFR). Somewhat surprisingly, we find that these galaxies are strong outliers from the BTFR, rotating too slowly for their baryonic mass. Moreover, their position in the circular velocity--baryonic mass plane implies that they have a baryon fraction inside their virial radii compatible with the cosmological mean, meaning that they have no "missing baryons". Unexpectedly, the dynamics of our galaxies are dominated by the baryons, leaving small room for dark matter inside their discs.

Denote by $q^ε_1(\cdot)$ the density of the law of $Ξ_1$ conditioned on $σ(Y_t^ε: 0\leq t\leq 1)$. We provide "quenched" large deviation estimates for the random family of measures $q^ε_1(x)dx$: there exists a continuous, explicit mapping $\bar J : R^2\to R$ such that for almost all $B_\cdot,V_\cdot$, $\bar J(\cdot,X_1)$ is a good rate function and for any measurable $G\subset R$, $$-\inf_{x\in G^o} \bar J(x,X_1) \leq \liminf ε\log \int_G q_1^ε(x) dx \leq \limsup ε\log \int_G q_1^ε(x) dx \leq -\inf_{x\in \bar G} \bar J(x,X_1) .$$

description: The clustering of active galactic nuclei (AGN) sheds light on their typical large (Mpc-scale) environments, which can constrain the growth and evolution of supermassive black holes. Here we measure the clustering of luminous X-ray-selected AGN in the Stripe 82X and XMM-XXL-North surveys around the peak epoch of black hole growth, in order to investigate the dependence of luminosity on large-scale AGN environment. We compute the auto-correlation function of AGN in two luminosity bins, $10^{43}\leq L_X<10^{44.5}$ erg s$^{-1}$ at $z\sim 0.8$ and $L_X\geq 10^{44.5}$ erg s$^{-1}$ at $z\sim 1.8$, and calculate the AGN bias taking into account the redshift distribution of the sources using three different methods. Our results show that while the less luminous sample has an inferred typical halo mass that is smaller than for the more luminous AGN, the host halo mass may be less dependent on luminosity than suggested in previous work. Focusing on the luminous sample, we calculate a typical host halo mass of $\sim 10^{13}$ M$_{\odot}~h^{-1}$, which is similar to previous measurements of moderate-luminosity X-ray AGN and significantly larger than the values found for optical quasars of similar luminosities and redshifts. We suggest that the clustering differences between different AGN selection techniques are dominated by selection biases, and not due to a dependence on AGN luminosity. We discuss the limitations of inferring AGN triggering mechanisms from halo masses derived by large-scale bias.

description: Suggested correspondence between a black hole and a highly excited elementary string is explored. Black hole entropy is calculated by computing the density of states for an open excited string. We identify the square root of oscillator number of the excited string with Rindler energy of black hole to obtain an entropy formula which, not only agrees at the leading order with the Bekenstein-Hawking entropy, but also reproduces the logarithmic correction obtained for black hole entropy in the quantum geometry framework. This provides an additional supporting evidence for correspondence between black holes and strings.

description: Since the discovery in 1772 of the triangular Lagrange points L4 and L5 in the gravitational field of two bodies moving under the sole influence of mutual gravitational forces, astronomers found a large number of minor celestial bodies around these points of the Sun-Jupiter, Sun-Earth, Sun-Mars and Sun-Neptune systems. The L4 and L5 points of the Earth and Moon may be empty due to the gravitational perturbation of the Sun. However, in 1961 Kordylewski found two bright patches near the L5 point, which may refer to an accumulation of interplanetary particles. Since that time this formation is called the Kordylewski dust cloud (KDC). Until now only a very few computer simulations studied the formation and characteristics of the KDC. To fill this gap, we investigated a three-dimensional four-body problem consisting of the Sun, Earth, Moon and one test particle, 1860000 times separately. We mapped the size and shape of the conglomeratum of particles not escaped from the system sooner than an integration time of 3650 days around L5. Polarimetric observations of a possible KDC around L5 are presented in the second part of this paper.

description: Neural Networks are currently one of the most widely deployed machine learning algorithms. In particular, Convolutional Neural Networks (CNNs), are gaining popularity and are evaluated for deployment in safety critical applications such as self driving vehicles. Modern CNNs feature enormous memory bandwidth and high computational needs, challenging existing hardware platforms to meet throughput, latency and power requirements. Functional safety and error tolerance need to be considered as additional requirement in safety critical systems. In general, fault tolerant operation can be achieved by adding redundancy to the system, which is further exacerbating the computational demands. Furthermore, the question arises whether pruning and quantization methods for performance scaling turn out to be counterproductive with regards to fail safety requirements. In this work we present a methodology to evaluate the impact of permanent faults affecting Quantized Neural Networks (QNNs) and how to effectively decrease their effects in hardware accelerators. We use FPGA-based hardware accelerated error injection, in order to enable the fast evaluation. A detailed analysis is presented showing that QNNs containing convolutional layers are by far not as robust to faults as commonly believed and can lead to accuracy drops of up to 10%. To circumvent that, we propose two different methods to increase their robustness: 1) selective channel replication which adds significantly less redundancy than used by the common triple modular redundancy and 2) a fault-aware scheduling of processing elements for folded implementations

description: We study two-dimensional supersymmetric non-linear sigma-models with boundaries. We derive the most general family of boundary conditions in the non-supersymmetric case. Next we show that no further conditions arise when passing to the N=1 model. We present a manifest N=1 off-shell formulation. The analysis is greatly simplified compared to previous studies and there is no need to introduce non-local superspaces nor to go (partially) on-shell. Whether or not torsion is present does not modify the discussion. Subsequently, we determine under which conditions a second supersymmetry exists. As for the case without boundaries, two covariantly constant complex structures are needed. However, because of the presence of the boundary, one gets expressed in terms of the other one and the remainder of the geometric data. Finally we recast some of our results in N=2 superspace and discuss applications.

Similarities (complete or partial) with supersymmetry that emerge in this special limit are discussed.

description: While the Advanced LIGO and Virgo gravitational-wave experiments now regularly observe binary black hole mergers, the evolutionary origin of these events remains a mystery. Analysis of the binary black hole spin distribution may shed light on this mystery, offering a means of discriminating between different binary formation channels. Using the data from Advanced LIGO and Virgo's first and second observing runs, here we seek to carefully characterize the distribution of effective spin among binary black holes, hierarchically measuring the distribution's mean $μ$ and variance $σ^2$ while accounting for selection effects and degeneracies between spin and other black hole parameters. We demonstrate that the known population of binary black holes have spins that are both small, with $μ\sim 0$, and very narrowly distributed, with $σ^2 \leq 0.07$ at 95% credibility. We then explore what these ensemble properties imply about the spins of individual binary black hole mergers, re-analyzing existing gravitational-wave events with a population-informed prior on their effective spin. The binary black hole GW170729, which previously excluded effective spin equal to zero, is now consistent with zero effective spin at ~10% credibility. More broadly, we find that uninformative spin priors generally yield overestimates for the effective spin magnitudes of compact binary mergers.

The black hole considered here is a solution to the low-energy string theory in 2+1 dimensions. It is asymptotic to the anti-de Sitter space. The exact values of quasinormal modes for the scalar perturbations are calculated. For both the charged and uncharged cases, the quasinormal frequencies are pure-imaginary leading to purely damped modes for the perturbations.

description: Most of the progress in high-energy Quantum Chromodynamics has been obtained within the eikonal approximation and infinite Wilson-line operators. Evolution equations of Wilson lines with respect to the rapidity parameter encode the dynamics of the hadronic processes at high energy. However, even at high energy many interesting aspects of hadron dynamics are not accessible within the eikonal approximation, the spin physics being an obvious example. The higher precision reached by the experiments and the possibility to probe spin dynamics at future Electron Ion Colliders make the study of deviations from eikonal approximation especially timely. In this paper, I derive the sub-eikonal quark and gluon propagators which can serve as a starting point of studies of these effects.

description: The holographic principle relates (classical) gravitational waves in the bulk to quantum fluctuations and the Weyl anomaly of a conformal field theory on the boundary (the brane). One can thus argue that linear perturbations in the bulk of static black holes located on the brane be related to the Hawking flux and that (brane-world) black holes are therefore unstable. We try to gain some information on such instability from established knowledge of the Hawking radiation on the brane. In this context, the well-known trace anomaly is used as a measure of both the validity of the holographic picture and of the instability for several proposed static brane metrics. In light of the above analysis, we finally consider a time-dependent metric as the (approximate) representation of the late stage of evaporating black holes which is characterized by decreasing Hawking temperature, in qualitative agreement with what is required by energy conservation.

description: Η εργασία με τίτλο «Ο ρόλος των χορών δούλων γυναικών ως δραματικών προσώπων στις τραγωδίες του Ευριπίδη» στοχεύει να επανεξετάσει τις παρατηρήσεις των μελετητών από την αρχαιότητα μέχρι και σήμερα, πως ο χορός του Ευριπίδη εμφανίζεται αποκομμένος από την τραγική πλοκή και πως η συμμετοχή του στο δράμα είναι ιδιαίτερα περιορισμένη. Στο πλαίσιο αυτό μελετάται ο δραματικός ρόλος του χορού σε τέσσερις τραγωδίες: την Εκάβη, τις Τρωάδες, την Ιφιγένεια εν Ταύροις και την Ελένη. Τη γενική παρουσίαση του ευριπίδειου χορού ακολουθεί μία ανάλυση της διπλά περιθωριακής ταυτότητας των αιχμάλωτων γυναικών στα εξεταζόμενα έργα καθώς και των ιδιαιτεροτήτων που αυτή παρουσιάζει. Κατόπιν, αναλύονται οι τρόποι με τους οποίους οι γυναίκες επιτελούν τις τρεις λειτουργίες που παραδοσιακά αναλαμβάνει ένας τραγικός χορός (ερμηνευτική, συναισθηματική, τελετουργική) καθώς και ο βαθμός συμμετοχής και εμπλοκής τους στα διάφορα μέρη της τραγωδίας. Επιπρόσθετα, η παρουσίαση της τεχνικής της «choral projection» που αξιοποιείται σε μεγάλο βαθμό από τον δραματουργό στις τραγωδίες που μελετώνται, καταμαρτυρά τη συνάφεια αυτής με την ιδιαίτερη ταυτότητα του χορού. Τέλος, η ανάλυση του ρόλου των αιχμάλωτων γυναικών ως δραματικών προσώπων (dramatis personae) σε καθένα από τα τέσσερα έργα αναδεικνύει τους ποικίλους τρόπους με τους οποίους ο Ευριπίδης αξιοποίησε τον τραγικό χορό, ενώ αποκαλύπτει την εξέλιξη του συγκεκριμένου χαρακτήρα στη δραματουργία του.
description: The master’s thesis titled «The captive women’s choruses as dramatis personae in Euripides’ tragedies» aims to reexamine the remarks of scholars since antiquity that the Euripidean chorus is detached from the tragic plot and has minimal involvement in the dramatic action. Within this framework, the present thesis focuses on four plays: Hecuba, Trojan Women, Iphigeneia in Tauris, Helen. This study provides a comprehensive analysis of the Euripidean chorus followed by a thorough examination of the captive women’s doubly marginal identity and its distinctive features. Moreover, this thesis investigates how the captive women fulfill the three traditional functions of the tragic chorus -emotional, hermeneutical, performative- while also assessing their modes of participation in different sections of the plays. Additionally, the examination of the technique of choral projection, which is notably prominent in the tragedies in question, sheds light on its connection to the chorus’s identity. Finally, the analysis of the role of captive women as dramatis personae in each of the four plays reveals how Euripides utilized the tragic chorus and how this character evolved in his dramaturgy.
A Perturbative Determination of Mass Dependent $O(a)$ Improvement Coefficients in a Relativistic Heavy Quark Action

description: We present the results for a perturbative determination of mass dependent improvement coefficients $ν$, $r_s$, $c_E$ and $c_B$ in a relativistic heavy quark action, which we have designed to control $m_Qa$ errors by extending the on-shell $O(a)$ improvement program to the case of $m_Q \gg Λ_{\rm QCD}$, where $m_Q$ is the heavy quark mass. The parameters $ν$ and $r_s$ are determined from the quark propagator and $c_E$ and $c_B$ are from the on-shell quark-quark scattering amplitude. We show that all the parameters, together with the quark wave function and the mass renormalization factors, are determined free from infrared divergences once their tree level values are properly tuned. Results of these parameters are shown as a function of $m_Q a$ for various improved gauge actions.

description: We report on deviations beyond the Born-Oppenheimer approximation in the potassium inter-atomic potentials. Identifying three up-to-now unknown $d$-wave Feshbach resonances, we significantly improve the understanding of the $^{39}$K inter-atomic potentials. Combining these observations with the most recent data on known inter- and intra-isotope Feshbach resonances, we show that Born-Oppenheimer corrections can be determined from atomic collisional properties alone and that significant differences between the homo- and heteronuclear case appear.

Compton Scattering in the Presence of Lorentz and CPT Violation

description: We examine the process of Compton scattering, in the presence of a Lorentz- and CPT-violating modification to the structure of the electron. We calculate the complete tree-level contribution to the cross section; our result is valid to all orders in the Lorentz-violating parameter. We find a cross section that differs qualitatively from the Klein-Nishina result at small frequencies, and we also encounter a previously undescribed complication that will arise in the calculation of many Lorentz-violation cross sections: The Lorentz violation breaks the spin degeneracy of the external states, so we cannot use a closure relation to calculate the unpolarized cross section.

description: The spectrum of charmonium resonances contains a number of unanticipated states along with several conventional quark-model excitations. The hadrons of different quantum numbers JP appear in a fairly narrow energy band, where JP refers to the spin-parity of a hadron in its rest frame. This poses a challenge for lattice QCD studies of (coupled-channel) meson-meson scattering aimed at the determination of scattering amplitudes and resonance pole positions. A wealth of information for this purpose can be obtained from the lattice spectra in frames with nonzero total momentum. These are particularly dense since hadrons with different JP contribute to any given lattice irreducible representation. This is because JP is not a good quantum number in flight, and also because the continuum symmetry is reduced on the lattice. In this paper we address the assignment of the underlying continuum JP quantum numbers to charmonia in flight using a Nf=2+1 Coordinated Lattice Simulations ensemble. As a first step, we apply the single-hadron approach, where only interpolating fields of quark-antiquark type are used. The approach follows techniques previously applied to the light meson spectrum by the Hadron Spectrum Collaboration. The resulting spectra of charmonia with assigned JP will provide valuable information for the parametrization of (resonant) amplitudes in future determinations of resonance properties with lattice QCD.

description: We study nonsingular cosmological scenarios in a general $D$-dimensional string effective action of the dilaton-modulus-axion system in the presence of the matter source. In the standard dilatonic Brans-Dicke parameter ($ω=-1$) with radiation, we analytically obtain singularity-free bouncing solutions where the universe starts out in a state with a finite curvature and evolves toward the weakly coupled regime. We apply this analytic method to the string-gas cosmology including the massive state in addition to the leading massless state (radiation), with and without the axion. We numerically find bouncing solutions which asymptotically approach an almost radiation-dominant universe with a decreasing curvature irrespective of the presence of the axion, implying that inclusion of the matter source is crucial for the existence of such solutions for $ω=-1$. In the theories with $ω\ne -1$, it is possible to obtain complete regular bouncing solutions with a finite dilaton and curvature in both past and future asymptotics for the general dimension, $D$. We also discuss the case where dilatonic higher-order corrections are involved to the tree-level effective action and demonstrate that the presence of axion/modulus fields and the matter source does not significantly affect the dynamics of the dilaton-driven inflation and the subsequent graceful exit.

description: We aim to investigate the overall properties of the ICRF3 with the help of the Gaia Data release 2 (Gaia DR2). This could serve as an external check of the quality of the ICRF3. The radio source positions of the ICRF3 catalog were compared with the Gaia DR2 positions of their optical counterparts at G < 18.7. Their properties were analyzed in terms of the dependency of the quoted error on the number of observations, on the declination, and the global difference, the latter revealed by means of expansions in the vector spherical harmonics. The ICRF3 S/X-band catalog shows a more smooth dependency on the number of observations than the ICRF1 and ICRF2, while the K and X/Ka-band yield a dependency discrepancy at the number of observations of about 50. The rotation of all ICRF catalogs show consistent results, except for the X-component of the X/Ka-band which arises from the positional error in the non-defining sources. No significant glides were found between the ICRF3 S/X-band component and Gaia DR2. However, the K- and X/Ka- band frames show a dipolar deformation in Y-component of +50μas and several quadrupolar terms of 50μas in an absolute sense. A significant glide along Z-axis exceeding 200 μas in the X/Ka-band was also reported. These systematics in the ICRF catalog are shown to be less dependent on the limiting magnitude of the Gaia sample when the number of common sources is sufficient (> 100). The ICRF3 S/X-band catalog shows improved accuracy and systematics at the level of noise floor. But the zonal errors in the X/Ka-band should be noted, especially in the context of comparisons of multi-frequency positions for individual sources.
