The Feasibility of Draglines for Mine Reclamation
Creators: name: Anderson, Mark
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1985
Subjects: subject: Transportation Engineering

description: Draglines are presented in this paper as an alternative for mine reclamation in steep sloping areas. Some abandoned mines in steep sloping areas of Kentucky have unreclaimed slopes which pose safety problems, as well as environmental and aesthetic problems. In addition, many active mines in steep sloping areas of Kentucky have slopes which must be reclaimed in the near future. Current methods of slope reclamation in Kentucky typically involve traditional heavy equipment. The current methods are not cost efficient in some cases, and are not safe in some applications.  The paper includes a history of draglines. Early development is summarized, and major improvements are discussed. Unreclaimed acreage in Kentucky and the mining and reclamation methods traditionally used for strip mines in Kentucky are discussed. The engineering feasibility of draglines is discussed. Bearing capacity and slope stability are presented as factors which influence the engineering feasibility of draglines in steep sloping areas. A presumptive value of hearing capacity for a typical spoil bank is calculated. The factor of safety against slope stability failure is discussed. A reclamation method which minimizes the risk of bearing or slope stability failures is presented. The economic feasibility of dragline reclamation is also presented. The initial cost and production costs of dragline equipment is compared to the initial cost and production costs of other reclamation equipment. In addition, the “crescent" scraper system is introduced as an alternative to conventional dragline bucket and line systems. A drag line equipped with a "Crescent” scraper system can reclaim very long slopes in steep areas which were previously considered unfeasible for dragline use.
Electrical control of magnon propagation in multiferroic BiFeO3 films

description: The spin wave spectra of multiferroic BiFeO3 films is calculated using a phenomenological Landau theory that includes magnetostatic effects. The lowest frequency magnon dispersion is shown to be quite sensitive to the angle between spin wave propagation vector and the Neel moment. Since electrical switching of the Neel moment has recently been demonstrated in this material, the sensitivity of the magnon dispersion permits direct electrical switching of spin wave propagation. This effect can be used to construct spin wave logical gates without current pulses, potentially allowing reduced power dissipation per logical operation.

description: Anomaly detection is concerned with identifying data patterns that deviate remarkably from the expected behaviour. This is an important research problem, due to its broad set of application domains, from data analysis to e-health, cybersecurity, predictive maintenance, fault prevention, and industrial automation. Herein, we review state-of-the-art methods that may be employed to detect anomalies in the specific area of sensor systems, which poses hard challenges in terms of information fusion, data volumes, data speed, and network/energy efficiency, to mention but the most pressing ones. In this context, anomaly detection is a particularly hard problem, given the need to find computing-energy accuracy trade-offs in a constrained environment. We taxonomize methods ranging from conventional techniques (statistical methods, time-series analysis, signal processing, etc.) to data-driven techniques (supervised learning, reinforcement learning, deep learning, etc.). We also look at the impact that different architectural environments (Cloud, Fog, Edge) can have on the sensors ecosystem. The review points to the most promising intelligent-sensing methods, and pinpoints a set of interesting open issues and challenges.

description: We consider generalizations of depolarizing channels to maps in which the identity channel is replaced by a convex combinations of unitary conjugations. We show that one can construct unital channels of this type for which the input which achieves maximal output purity is unique. We give conditions under which multiplicativity of the maximal p-norm and additivity of the minimal output entropy. We also show that the Holevo capacity need not equal log d - the minimal entropy as one might expect for a convex combination of unitary conjugations. Conversely, we give examples for which this condition holds, but the channel has no evident covariance properties.
description: Added a few references in v4. Previously added a section on numerical studies giving evidence for additivity of channel capacity, and comments on the relationship to quant-ph/0412133 and quant-ph/0505022

description: The COMET experiment at J-PARC aims to search for the neutrinoless transition of a muon to an electron. We have developed the readout electronics board called ROESTI for the COMET straw tube tracker. We plan to install the ROESTI in the gas manifold of the detector. The number of vacuum feedthroughs needs to be reduced due to space constraints and cost limitations. In order to decrease the number of vacuum feedthroughs drastically, we developed a network processor with a daisy-chain function of Gigabit Ethernet for the FPGA on the ROESTI. We implemented two SiTCPs, which are hardware-based TCP processors for Gigabit Ethernet, in the network processor. We also added the data path controllers which handle the Ethernet frames and the event data. The network processor enables ROESTI to process the slow control over UDP/IP and to transfer event data over TCP/IP. By using the network processor, we measured the throughput, the stability, and the data loss rate for two to six ROESTIs. In any number of boards, the throughput of the event data transfer achieved the theoretical limit of TCP over the Gigabit Ethernet stably and ROESTI stably sent 100% of the data.

description: We consider the metric exterior to a charged dilaton black hole in a de Sitter universe. We study the motion of a test particle in this metric. Conserved quantities are identified and the Hamilton-Jacobi method is employed for the solutions of the equations of motion. At large distances from the black hole the Hubble expansion of the universe modifies the effective potential such that bound orbits could exist up to an upper limit of the angular momentum per mass for the orbiting test particle. We then study the phenomenon of strong field gravitational lensing by these black holes by extending the standard formalism of strong lensing to the non-asymptotically flat dilaton-de Sitter metric. Expressions for the various lensing quantities are obtained in terms of the metric coefficients.

The extended method is illustrated by several examples, corresponding both to $\hbar$-independent superpotentials and to a superpotential explicitly depending on $\hbar$.

description: The LHC has released precise measurements of elastic proton-proton scattering that provide a unique constraint on the asymptotic behavior of the scattering amplitude at high energies. Recent reanalyses of part of these data indicate that the central values of some forward quantities would be different than initially observed. We introduce correlation information between the original and the reanalyzed data sets in a way suitable for a global fitting analysis of all data. The careful treatment of correlated errors leads to much less stringent limits on the $ρ$ uncertainty and sets up the stage for describing the forward data using a scattering amplitude dominated by only crossing-even terms. In the light of these correlated data we determine the parameters of the soft Pomeron from the Regge theory. We use Born-level and eikonalized amplitudes. In the Born-level case we estimate the contribution of the double Pomeron exchange, while in the latter case we investigate the role of the eikonalization in both the one- and two-channel models. The role of the proton-Pomeron vertex form and of the nearest $t$-channel singularity in the Pomeron trajectory receives particular attention. We discuss the implications of our results and present predictions for the total cross section and the $ρ$ parameter in proton-proton collisions at LHC and cosmic ray energies.

description: We are discussing certain combinatorial and counting problems related to quadratic algebras. First we give examples which confirm the Anick conjecture on the minimal Hilbert series for algebras given by n generators and n(n-1)/2 relations for n less or equal then 7. Then we investigate combinatorial structure of colored graph associated to relations of RIT algebra. Precise descriptions of graphs (maps) corresponding to algebras with maximal Hilbert series are given in certain cases. As a consequence it turns out, for example, that RIT algebra may have a maximal Hilbert series only if components of the graph associated to each color are pairwise 2-isomorphic.

description: We present multi-colour photometry of four field ultracool dwarfs with the triple-beam photometer ultracam. Data were obtained simultaneously in the Sloan-g' band and a specially designed narrow-band NaI filter. The previously reported 1.8-hr period of Kelu-1 is here recovered in the g'-band, but the lack of any significant variability in the NaI light of this object precludes any conclusion as to the cause of the variability. 2MASS 2057-0252 and DENIS 1441-0945 show no convincing evidence for variability. 2MASS 1300+1912, on the other hand, shows good evidence for gradual trends in both bands at the 5% level. These trends are anti-correlated at a high level of significance, a result which is incompatible with models of starspot-induced variability. It would seem likely that dust cloud "weather" is responsible for the short-term variability in this object.

If $\mathcal{F}$ deforms along a first order deformation of $X$, its Mukai vector remains of Hodge type along this deformation. We prove an analogous statement for all polyvector fields, not only for those in $H^1(X,T_X)$ corresponding to deformations of the complex structure. This answers a question of Markman. We also explore a Lie theoretic analogue of the statement above.

description: Vertically vibrated rod-shaped granular materials confined to quasi-2D containers self organize into distinct patterns. We find, consistent with theory and simulation, a density dependent isotropic-nematic transition. Along the walls, rods interact sterically to form a wetting layer. For high rod densities, complex patterns emerge as a result of competition between bulk and boundary alignment. A continuum elastic energy accounting for nematic distortion and local wall anchoring reproduces the structures seen experimentally.

Novel approaches to insulin mimetic vanadium compounds

description: Novel approaches to the synthesis of insulin mimetic vanadium compounds were explored. Derivatives of the potent insulin mimetic complex VO(ema)2 or bis(ethylmaltolato)oxovanadium(IV) were successfully synthesized, including the highly lipophilic Hema (ethylmaltol) adduct [VO(ema)2(Hema)]•H2O, as well as [VOCI(Hema)2]CI•H2O, a water-soluble salt form of VO(ema)2. [VO(ema)2(Hema)]•H2O, VO(ema)2 and [VOCI(Hema)2]CI•H2O were characterized in the solid state by infrared spectroscopy, mass spectrometry and elemental analysis. [VO(ema)2(Hema)]•H2O and [VOCI(Hema)2]CI•H2O are hydrolytically unstable and serve as VO(ema)2 procomplexes and potential prodrugs. VO(ema)2 was characterized in aqueous solution through a combination of spectrophotometry, electron paramagnetic resonance spectroscopy and potentiometry. VO(ema)2 was found to be stable to hydrolysis. Novel vanadium(lll) complexes were synthesized, including V(ma)3or tris(maltolato)vanadium(lll), V(ema)3 or tris(ethylmaltolato)vanadium(lll), V(koj)3•H2O or tris(kojato)vanadium(lll) monohydrate and V(dpp)3•12H2O or tris(1,2-dimethyl-3- oxy-4-pyridinonato)vanadium(lll) dodecahydrate, and were characterized in the solid state by infrared spectroscopy, mass spectrometry and elemental analysis. The X-ray structure determination of V(dpp)3*12H2O is reported. V(ma)3, V(ema)3 and V(koj)3•H2O were found to be hydrolytically stable at physiological pH through potentiometry. In the first examination of a vanadium(lll) complex for insulin-enhancing activity, administration of V(ma)3 was found to normalize blood glucose levels in STZ-diabetic rats. Neutral oxovanadium(V) complexes including V2O3(ema)4, VO(fla)2(OCH3 ) or bis(flavonato)methoxyoxovanadium(V) and [VO2(dpp)]•Hdpp•H2O were synthesized and characterized by infrared spectroscopy, mass spectrometry and elemental analysis.

description: Without a cure, vaccine, or proven long-term immunity against SARS-CoV-2, test-trace-and-isolate (TTI) strategies present a promising tool to contain its spread. For any TTI strategy, however, mitigation is challenged by pre- and asymptomatic transmission, TTI-avoiders, and undetected spreaders, who strongly contribute to hidden infection chains. Here, we studied a semi-analytical model and identified two tipping points between controlled and uncontrolled spread: (1) the behavior-driven reproduction number of the hidden chains becomes too large to be compensated by the TTI capabilities, and (2) the number of new infections exceeds the tracing capacity. Both trigger a self-accelerating spread. We investigated how these tipping points depend on challenges like limited cooperation, missing contacts, and imperfect isolation. Our model results suggest that TTI alone is insufficient to contain an otherwise unhindered spread of SARS-CoV-2, implying that complementary measures like social distancing and improved hygiene remain necessary.
Aerodynamic Effects of Gurney Flaps on the Rotor Blades of a Research Wind Turbine
Creators: name: Alber, Joerg
Publisher: name: Zenodo
Year: 2019

description: One reason for structural fatigue-loads on HAWT rotor-blades are relatively high angles-of-attack (AoA) towards the root-region due to structural constraints regarding chord-length and twist-angles. The current research project investigates a blade-optimization strategy, the Gurney flap (GF). This passive flow control device (PFC) is attached perpendicular to the pressure side at the trailing edge, influencing the flow-field such that both lift and drag forces are increased. Consequently, the axial and the tangential inductions are augmented leading to an AoA-reduction, potentially alleviating detrimental stall-effects due to early Separation. Furthermore, an energy yield improvement is achieved applying GF in the root-region of the DTU 10 MW Reference Turbine. The Berlin Research Turbine (BeRT) is a test-bench inside the large low-speed section (4.2mx4.2m) of the closed loop wind-tunnel of the Technical University of Berlin. The rotor radius measures R=1.5m and the blades are based on a Clark-Y airfoil. The tip speed ratio at rated conditions is TSR=4.3 at a Reynolds-number range of 250,000. The three rotor-blades were equipped with GF in order to determine the aerodynamic impact under reproducible wind tunnel conditions. The operational points of all experiments covered a broad range of 3<TSR<6 and 3°<AoA<17°.The baseline configurations included the clean and the rough baseline cases, i.e. the application of Zig Zag tape (ZZ) forcing the boundary-layer transition to occur close to the leading edge on both suction and pressure sides. GF were attached to all three blades and throughout the whole blade-span, except for the tip-section, including three different GF-heights relative to the respective chord-length of 1%c, 0.5%c and 0.3%c.The axial and tangential inductions, as well as the resulting local AoA, were determined based on wake-velocity measurements using a 3D Ultrasonic Anemometer, which was installed mid-span at around 1R downstream of the rotor. Simultaneously, the local pressure distribution was measured by a total of 30 pressure ports, which were positioned mid-span of both the pressure and the suction side. Furthermore, the blade- and tower bending moments were evaluated by means of strain gauges at the blade-root as well as the tower-foundation. The results show that GF generate a significant impact on the flow-field of rotor-blades, which is quantifiable and reproducible by using different sensors. Depending on the GF-height, the axial and the tangential inductions, and thus the bending moments, are increased while the AoA are reduced. Furthermore, a substantial augmentation of the local pressure difference was detected. Hence, GFs are considered an effective PFC device for optimizations of the inbound blade-region and especially when taking roughness-effects due to surface erosion into account.

description: Prostate cancer is the most common cancer diagnosed in many countries and the third most common cause of cancer death. However prognostic models for overall survival for patients are dated. The Challenge calls upon the computational biology community to find solutions to unanswered clinical questions about metastatic castrate-resistant prostate cancer (mCRPC) and explore data modeling approaches.

The main advantage of ensembles of different models is that it is unlikely that all models will make the same mistake. Ensembles tend to reduce the variance of models. Therefore, we apply ensemble approaches to deal with the prediction problems in this challenge. In the leaderboard, our approaches outperform the baseline and the methods of many teams.

description: We show that the issue of the drag exerted by an incompressible fluid on a body in uniform motion has played a major role in the early development of fluid dynamics. In 1745 Euler came close, technically, to proving the vanishing of the drag for a body of arbitrary shape; for this he exploited and significantly extended existing ideas on decomposing the flow into thin fillets; he did not however have a correct picture of the global structure of the flow around a body. Borda in 1766 showed that the principle of live forces implied the vanishing of the drag and should thus be inapplicable to the problem. After having at first refused the possibility of a vanishing drag, d'Alembert in 1768 established the paradox, but only for bodies with a head-tail symmetry. A full understanding of the paradox, as due to the neglect of viscous forces, had to wait until the work of Saint-Venant in 1846.

description: The Kentucky Transportation Research Program has completed a laboratory study involving the use of flue gas desulfurization sludge (scrubber sludge) for potential application as a highway subbase and/or embankment material. Scrubber sludge is a waste produet formed when fly ash (and other residue) is combined with a lime dust slurry filter cake and stabilized with quicklime (calcium oxide). Samples of stockpiled (field) sludge and dry sludge components were obtained from the Robert Reid Station (Big Rivers Electric Corporation) in Sebree, Kentuclty. Dry sludge components (fly ash, filter cake, and quicklime) were uaed to prepare sludge samples in the laboratory, allowing a higher degree of quality control for compariaon purposes. Mixtures for testing included scrubber sludge, scrubber sludge with pond ash (bottom ash), and scrubber sludge with dense graded limestone aggregate (DGA). One objective of laboratory analyses was the determination of optimum mixture proportions. A mixture of 20-percent scrubber sludge and 80-percent pond ash was determined to be the optimum design mix. That mixture showed significant strength gain with curing and had a static-chord modulus of elasticity approximately 118 times the compressive strength. Strength and modulus tests indicated that mixtures of scrubber sludge and pond ash were superior to mixtures of scrubber sludge and DGA. The scope of the study, however, did not permit complete explanation of these observations. An economic study showed that scrubber sludge with pond ash can be used economically as a highway subbase material, especially on low-fatigue roads, by partially replacing more expensive pavement layers. Triaxial tests and computer simulations indicated that scrubber sludge could be used as an embankment material in some applications. However, this would be economical only if suitable fill material was not available at or near the fill site.

Ultraviolet suppression and nonlocality in optical model potentials for nucleon-nucleus scattering

description: We investigate the role of high momentum components of optical model potentials for nucleon-nucleus scattering and its incidence on their nonlocal structure in coordinate space. The study covers closed-shell nuclei with mass number in the range $4\leq A\leq 208$, for nucleon energies from tens of MeV up to 1 GeV. To this purpose microscopic optical potentials are calculated using density-dependent off-shell $g$ matrices in Brueckner-Hartree-Fock approximation and based on Argonne $v_{18}$ as well as chiral 2$N$ force up to next-to-next-to-next-to-leading order. We confirm that the gradual suppression of high-momentum contributions of the optical potential results in quite different coordinate-space counterparts, all of them accounting for the same scattering observables. We infer a minimum cutoff momentum $Q$, function of the target mass number and energy of the process, that filters out irrelevant ultraviolet components of the potential. We find that when ultraviolet suppression is applied to Perey-Buck nonlocal potential or local Woods-Saxon potentials, they also result nonlocal with similar appearance to those obtained from microscopic models in momentum space. We examine the transversal nonlocality, quantity that makes comparable the intrinsic nonlocality of any potential regardless of its representation. We conclude that meaningful comparisons of nonlocal features of alternative potentials require the suppression of their ultraviolet components.

description: We have obtained mosaic images of NGC 3109 in the V and I bands on 74 nights, spanning approximately one year. From these data, we have conducted an extensive search for Cepheid variables over the entire field of the galaxy, resulting in the discovery of 113 variables with periods ranging from 3.4 to 31.4 days. In this sample, 76 Cepheids, including many long-period variables, were not known before. For the previously known 45 Cepheids in this galaxy, our data proved that reported periods were wrong for 14 objects; for nearly all other previously known Cepheid variables we were able to significantly improve on the periods. We construct period-luminosity relations from our data and obtain reddening-corrected distance moduli of 25.72 $\pm$ 0.05 mag in V, and 25.66 $\pm$ 0.04 mag in I. The distance modulus derived form the reddening-independent V-I Wesenheit index turns out to be significantly shorter (25.54 $\pm$ 0.05 mag), which indicates that in addition to the foreground extinction of E(B-V) = 0.05 mag, there is an intrinsic to NGC 3109 redening of about 0.05 mag. Our distance obtained based on the reddening-free Wesenheit magnitudes is consistent with earlier distance determinations of NGC 3109 from Cepheids, and the tip of the red giant branch. We will improve on our distance and extinction determination combining our optical data with the follow-up near-infrared observations of a subsample of NGC 3109 Cepheids.

The development of the list of reduction factors was based mainly on a review of literature and survey of states, with limited input from a before-and-after accident analysis.
title: THE DYNAMICS OF SUPPLY CHAIN INTEGRATION: EMPIRICAL EVIDENCE FROM PUBLIC HEALTH SUPPLY CHAINS IN KADUNA STATE, NIGERIA
Creators: name: Abdulkadir, R

description: The Kaduna State supply chain transformation initiative aims to integrate all state-fragmented supply chains to improve medicine availability performance. Supply chain integration enables organisations to collaboratively work with medicine suppliers and customers to achieve cost savings and improve service delivery, lead times, and performance. This study empirically assesses public healthcare supply chains and builds a dynamic theory of integrated healthcare supply chains based on systems dynamics. Underpinned by systems engineering theory and the system dynamics integrative paradigm, this study used interplay paradigm crossing in a mixed-method multiple case study to measure the availability of medicines in five public healthcare supply chains and developed a dynamic hypothesis from the mental models of system actors to increase the Medicine Fill Rate (MFR). Constraints in each supply chain were analysed to understand the perception of the structure, feedbacks, and dynamic behaviours that drive medicine availability. A network conceptual model was used to design a three-tiered stock-and-flow model for an integrated supply chain. Policies for financial management, government funding, order management, and inventory management were developed and tested to achieve a 90% MFR. 

The findings of this study show that the five supply chains can benefit from integration by forming strategic alliances with suppliers for pooled procurement. Sharing resources, risks, and benefits through the adoption of digital platforms to improve communication, visibility, and trust serves as a fulcrum for network integration. The use of supply chain finance and a performance-driven approach by the integrated network assists in breaking the capability and bailout trap of resource dependency on government funding. This study enriches the development of a dynamic theory of supply chain integration that will benefit managers, essential medicine stakeholders, donors, and policymakers by developing network-revolving fund model policies to reduce medicine stockouts and increase essential MFR for the treatment of diseases.

description: We describe a laboratory demonstration of a quantum error correction procedure that can correct intrinsic measurement errors in linear-optics quantum gates. The procedure involves a two-qubit encoding and fast feed-forward-controlled single-qubit operations. In our demonstration the qubits were represented by the polarization states of two single-photons from a parametric down-conversion source, and the real-time feed-forward control was implemented using an electro-optic device triggered by the output of single-photon detectors.

description: The objective of this study was to evaluate the effectiveness of the traffic noise barrier on I 471 in Campbell County, Kentucky. Since the barrier coincided with construction of I 471, it was necessary to predict noise levels that would exist if no barrier were present utilizing the FHWA STAMINA 2.0 computer model. This was compared to actual noise level measurements at the barrier site to determine the barrier insertion loss.  After calibration of the STAMINA 2.0 model, noise measurements were conducted at 39 receiver locations during off-peak and peak traffic conditions. The noise barrier reduced the noise level reaching adjacent residences substantially. Twenty-one residences (20 percent of the total in the study area) experienced a peak L10 insertion loss of 10 dBA or more, while another 63 residences (58 percent) were estimated as receiving an insertion loss of 5.0 to 9.9 dBA.  Comparison of insertion loss using levels predicted by the STAMINA 2.0 model with the barrier in place and measured levels were very close. Analyses indicated that insertion loss values predicted by the STAMINA 2.0 model will be achieved by the noise barrier .  A survey of community perception of the noise barrier was performed. Of 103 questionnaires delivered, 66 (64 percent) were returned. The community perception of the barrier was favorable, as 64 percent of the respondents generally liked the noise barrier and 95 percent felt it was effective in reducing traffic noise.
Weber's class number problem and $p$-rationality in the cyclotomic $\widehat{\mathbb{Z}}$-extension of $\mathbb{Q}$

description: Let $K$ be the $N$th layer in the cyclotomic $\widehat{\mathbb{Z}}$-extension $\widehat{\mathbb{Q}}$. Many authors (Aoki, Fukuda, Horie, Ichimura, Inatomi, Komatsu, Miller, Morisawa, Nakajima, Okazaki, Washington,\,$\ldots$) analyse the behavior of the $p$-class groups ${\mathcal C}_K$. We revisit this problem, in a more conceptual form, since computations show that the $p$-torsion group ${\mathcal T}_K$ of the Galois groups of the maximal abelian $p$-ramified pro-$p$-extension of $K$ (Tate--Shafarevich group of $K$) is often non-trivial; this raises questions since $\# {\mathcal T}_K = \# {\mathcal C}_K\, \# {\mathcal R}_K$ where ${\mathcal R}_K$ is the normalized $p$-adic regulator. We give a new method testing ${\mathcal T}_K \ne 1$ (Theorem 4.6, Table 6.2) and characterize the $p$-extensions $F$ of $K$ in $\widehat{\mathbb{Q}}$ with ${\mathcal C}_F \ne 1$ (Theorem 7.5 and Corollary 7.6). We publish easy to use programs, justifying again the eight known examples, and allowing further extensive computations.

description: The recent detection of GW190521 stimulated ideas on how to populate the predicted black hole pair-instability mass gap. One proposed scenario is the dynamical merger of two stars below the pair instability regime forming a star with a small core and an over-sized envelope. We explore this scenario with detailed stellar evolution calculations, starting with ad-hoc initial conditions enforcing no core growth during the merger. We outline the main challenges this scenario has to overcome, in particular the requirement to retain enough of its mass at merger time, in the subsequent evolution, and at core-collapse. We found that these massive merger products are likely helium-rich, and spend most of their remaining lifetime within regions of the Herzsprung-Russell diagram where envelope instabilities akin to luminous blue variable (LBV) eruptions are expected. An energetic estimate of the amount of mass loss neglecting the back-reaction of the star suggests that the total amount of mass that can be removed at low metallicity is . 1 M . This is small enough that at core-collapse our models are retaining sufficient mass to form black holes in the pair-instability gap similar to the recent ones detected by LIGO/Virgo. However, mass loss at the time of merger and the neutrino-driven mass loss at core collapse still need to be quantified for these models in order to confirm the viability of this scenario.

description: Three brown dwarfs in different evolutionary stages have been observed with the Chandra X-ray Observatory. Combining the new observations with previous studies presented in the literature yields a brown dwarf sample that reaches well down into the cooling phase of brown dwarfs, allowing to investigate the possible influence of effective temperature on X-ray activity. Combining our results with published data allows us to consider a subsample of high-mass brown dwarfs (with 0.05-0.07 Msun), and another one characterized by similar effective temperature (with 2400-2800 K). Our findings support the idea that effective temperature plays a critical role for the X-ray activity in brown dwarfs. This underlines an earlier suggestion based on observations of chromospheric Ha emission in ultracool dwarfs that the low ionization fraction in the cool brown dwarf atmospheres may suppress magnetic activity.

Investigations of Zeros Near the Central Point of Elliptic Curve L-Functions

description: We explore the effect of zeros at the central point on nearby zeros of elliptic curve L-functions, especially for one-parameter families of rank r over Q. By the Birch and Swinnerton Dyer Conjecture and Silverman's Specialization Theorem, for t sufficiently large the L-function of each curve E_t in the family has r zeros (called the family zeros) at the central point. We observe experimentally a repulsion of the zeros near the central point, and the repulsion increases with r. There is greater repulsion in the subset of curves of rank r+2 than in the subset of curves of rank r in a rank r family. For curves with comparable conductors, the behavior of rank 2 curves in a rank 0 one-parameter family over Q is statistically different from that of rank 2 curves from a rank 2 family. Unlike excess rank calculations, the repulsion decreases markedly as the conductors increase, and we conjecture that the r family zeros do not repel in the limit. Finally, the differences between adjacent normalized zeros near the central point are statistically independent of the repulsion, family rank and rank of the curves in the subset. Specifically, the differences between adjacent normalized zeros are statistically equal for all curves investigated with rank 0, 2 or 4 and comparable conductors from one-parameter families of rank 0 or 2 over Q.

description: The detection of gravitational-wave signals from coalescing eccentric binary black holes would yield unprecedented information about the formation and evolution of compact binaries in specific scenarios, such as dynamical formation in dense stellar clusters and three-body interactions. The gravitational-wave searches by the ground-based interferometers, LIGO and Virgo, rely on analytical waveform models for binaries on quasicircular orbits. Eccentric merger waveform models are less developed, and only few numerical simulations of eccentric mergers are publicly available, but several eccentric inspiral models have been developed from the post-Newtonian expansion. Here we present a novel method to convert the dominant quadrupolar mode of any circular analytical binary-black-hole model into an eccentric model. First, using numerical simulations, we examine the additional amplitude and frequency modulations of eccentric signals that are not present in their circular counterparts. Subsequently, we identify suitable analytical descriptions of those modulations and interpolate key parameters from twelve numerical simulations designated as our training dataset. This allows us to reconstruct the modulated amplitude and phase of any waveform up to mass ratio 3 and eccentricity 0.2. We find that the minimum overlap of the new model with numerical simulations is around 0.98 over all of our test dataset that are scaled to a 50M$_\odot$ black-hole binary starting at 35 Hz with aLIGO A+ design sensitivity. A Python package \pyrex easily carries out the computation of this method.

description: Recently, it has been shown that the minimum number of gauge invariant couplings for $B$-field, metric and dilaton at order $α'^3$ is 872. These couplings, in a particular scheme, appear in 55 different structures. In this paper, up to an overall factor, we fix all parameters in type II supertirng theories by requiring the reduction of the couplings on a circle to be invariant under T-duality transformations. We find that there are 445 non-zero couplings which appear in 15 different structures. The couplings are fully consistent with the partial couplings that have been found in the literature by the four-point S-matrix element and by the non-linear Sigma model methods.
