Concepts for direct frequency-comb spectroscopy of $^{229\text{m}}$Th and an internal-conversion-based solid-state nuclear clock

description: A new concept for narrow-band direct nuclear laser spectroscopy of $^{229\text{m}}$Th is proposed, using a single comb mode of a vacuum ultraviolet frequency comb generated from the 7th harmonic of an Yb-doped fiber laser system. In this concept more than $10^{14}$ $^{229}$Th atoms on a surface are irradiated in parallel and a successful nuclear excitation is probed via the internal-conversion (IC) decay channel. A net scanning time of 15 minutes for the most recent 1~$σ$ energy uncertainty interval of 0.34 eV appears to be achievable when searching for the nuclear transition. In case of successful observation, the isomer's energy value would be constrained to an uncertainty of about 100~MHz, which is a factor of $10^6$ of improvement compared to today's knowledge. Further, the comb mode could be stabilized to the nuclear transition using the same detection method, allowing for the development of an IC-based solid-state nuclear clock, which is shown to achieve the same performance as a crystal-lattice nuclear clock, however, with the advantage of a drastically simpler detection scheme. Finally, it is shown that the same laser system could be used to narrow down the isomer's transition energy by further six orders of magnitude during laser excitation of $^{229}$Th$^{3+}$ ions in a Paul trap and to drive nuclear Rabi oscillations, as required for the development of a nuclear clock based on a single $^{229}$Th$^{3+}$ ion.

description: In this note, we present a version of Hoeffding's inequality in a continuous-time setting, where the data stream comes from a uniformly ergodic diffusion process. Similar to the well-studied case of Hoeffding's inequality for discrete-time uniformly ergodic Markov chain, the proof relies on techniques ranging from martingale theory to classical Hoeffding's lemma as well as the notion of deviation kernel of diffusion process. We present two examples to illustrate our results. In the first example we consider large deviation probability on the occupation time of the Jacobi diffusion, a popular process used in modelling of exchange rates in mathematical finance, while in the second example we look at the exponential functional of a finite interval analogue of the Ornstein-Uhlenbeck process introduced by Kessler and Sørensen (1999).
New algorithms and technologies for the un-supervised reduction of Optical/IR images
Creators: name: Vandame, Benoit
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: This paper presents some of the main aspects of the software library that has been developed for the reduction of optical and infrared images, an integral part of the end-to-end survey system being built to support public imaging surveys at ESO. Some of the highlights of the new library are: unbiased estimates of the background, critical for deep IR observations; efficient and accurate astrometric solutions, using multi-resolution techniques; automatic identification and masking of satellite tracks; weighted co-addition of images; creation of optical/IR mosaics, and appropriate management of multi-chip instruments. These various elements have been integrated into a system using XML technology for setting input parameters, driving the various processes, producing comprehensive history logs and storing the results, binding them to the supporting database and to the web. The system has been extensively tested using deep images as well as images of crowded fields (e.g. globular clusters, LMC), processing at a rate of 0.5 Mega-pixels per second using a DS20E ALPHA computer with two processors. The goal of this presentation is to review some of the main features of this package.

In this article, applying p-adic and adelic quantum mechanics, we show existence of the corresponding vacuum eigenstates. Adelic wave function contains some information on discrete structure of space-time at the Planck scale.

description: Anthrax pharaonis Paramonov, 1935 (Figure 16 (c))
 Anthrax pharaonis Paramonov, 1935: 15, 30 (key only) [1936: 138]. Type locality: Egypt [holotype destroyed in EFC, and a neotype is herein designated].
 Diagnosis
 Female: Body brown-black to black, about 9.5 mm in length (Figure 16 (c)). Head dusted grey. Frons and face densely covered with black hairs, with only two bare stripes under the antennae; with numerous yellowish scales intermixed in the frons. Tip of oral margin appears sharply pointed when seen from below, not arched as in most other Anthrax spp. The oral cavity is extremely narrow, significantly narrower than the width of the vertex. Antennae with black hairs; flagellum onion-shaped, wider than pedicel, with the narrow part short, almost half the length of the basal part, and the stylus long, almost as long as the narrow part; pedicel lens-like in shape; scape slightly wider and almost 3 times longer than pedicel. Occiput covered with white scales. Bristles and hairs on scutum and scutellum almost yellowish, mixed with only a few sparse, weak black hairs on scutellum and posterior margin of scutum. Legs brown-black to black; fore tibiae yellowish; femora covered with yellowish scales, while tibiae and tarsi covered with blackish scales. Haltere yellowish. Wings almost entirely hyaline. Cell r5 significantly narrowed at wing margin. Abdomen densely covered with yellowish scales; 1st segment and sides of all segments with yellowish hairs, in addition to a few black hairs on the posterior margins of last segments. Anterior margins of 2nd to 5th tergites broadly covered with black scales.
 Remarks
 This species resembles those of the genus Villa in general appearance. Specimens could not be dissected.
 Neotype designation
The holotype of this species at ESEC was destroyed. Fortunately, two female specimens with the same locality and date of collection as the holotype (i.e. topotypes) were found preserved in EFC. These specimens were compared with the holotype and identified by the late Prof. Efflatoun Bey, i.e. they are considered homeotypes. To clarify the taxonomic status of the species and for nomenclatural stability, the best preserved of the two specimens is herein designated a neotype.
 Material examined
Neotype (herein designated), female, Mariout (31.0172°N, 29.7600°E), 24 May 1925; another specimen (topotype): same data as neotype [EFC].

description: We evaluated all two-loop conformal integrals appearing in five-point correlation functions of protected operators of $ \mathcal{N} $ = 4 Super Yang-Mills in several kinematical regimes. Starting from the correlation function of the lightest operators of the theory, we were able to extract structure constants of up to two spinning operators for small and large values of spin and the tensor structure label (polarization). We conjectured an universal all-loop behaviour for the large-spin, small-polarization structure constants and comment on the subtleties of analytically continuing it from finite to large spin. We also consider correlation functions of heavier operators that get factorized in the more fundamental object called decagon. We fixed this object at two loops in general kinematics and studied its physical properties under OPE and null limits.

Modeling of Missing Dynamical Systems: Deriving Parametric Models using a Nonparametric Framework

description: In this paper, we consider modeling missing dynamics with a nonparametric non-Markovian model, constructed using the theory of kernel embedding of conditional distributions on appropriate Reproducing Kernel Hilbert Spaces (RKHS), equipped with orthonormal basis functions. Depending on the choice of the basis functions, the resulting closure model from this nonparametric modeling formulation is in the form of parametric model. This suggests that the success of various parametric modeling approaches that were proposed in various domains of applications can be understood through the RKHS representations. When the missing dynamical terms evolve faster than the relevant observable of interest, the proposed approach is consistent with the effective dynamics derived from the classical averaging theory. In the linear Gaussian case without the time-scale gap, we will show that the proposed non-Markovian model with a very long memory yields an accurate estimation of the nontrivial autocovariance function for the relevant variable of the full dynamics. Supporting numerical results on instructive nonlinear dynamics show that the proposed approach is able to replicate high-dimensional missing dynamical terms on problems with and without the separation of temporal scales.

description: A universal scheme is introduced to speed up the dynamics of a driven open quantum system along a prescribed trajectory of interest. This framework generalizes counterdiabatic driving to open quantum processes. Shortcuts to adiabaticity designed in this fashion can be implemented in two alternative physical scenarios: one characterized by the presence of balanced gain and loss, the other involves non-Markovian dynamics with time-dependent Lindblad operators. As an illustration, we engineer superadiabatic cooling, heating, and isothermal strokes for a two-level system, and provide a protocol for the fast thermalization of a quantum oscillator.

description: We present chemical abundances for the elements carbon, sodium, and fluorine in 15 red giants of the globular cluster M 4, as well as six red giants of the globular cluster $ω$ Centauri. The chemical abundances were calculated in LTE via spectral synthesis. The spectra analyzed are high-resolution spectra obtained in the near-infrared region around $λ$2.3$μ$m with the Phoenix spectrograph on the 8.1m Gemini South Telescope, the IGRINS spectrograph on the McDonald Observatory 2.7m Telescope, and the CRIRES spectrograph on the ESO 8.2m Very Large Telescope. The results indicate a significant reduction in the fluorine abundances when compared to previous values from the literature for M 4 and $ω$ Centauri, due to a downward revision in the excitation potentials of the HF(1-0) R9 line used in the analysis. The fluorine abundances obtained for the M 4 red giants are found to be anti-correlated with those of Na, following the typical pattern of abundance variations seen in globular clusters between distinct stellar populations. In M 4, as the Na abundance increases by $\sim$+0.4 dex, the F abundance decreases by $\sim$-0.2 dex. A comparison with abundance predictions from two sets of stellar evolution models finds that the models predict somewhat less F depletion ($\sim$-0.1 dex) for the same increase of +0.4 dex in Na.

description: A critical task in single-cell RNA sequencing (scRNA-Seq) data analysis is to identify cell types from heterogeneous tissues. While the majority of classification methods demonstrated high performance in scRNA-Seq annotation problems, a robust and accurate solution is desired to generate reliable outcomes for downstream analyses, for instance, marker genes identification, differentially expressed genes, and pathway analysis. It is hard to establish a universally good metric. Thus, a universally good classification method for all kinds of scenarios does not exist. In addition, reference and query data in cell classification are usually from different experimental batches, and failure to consider batch effects may result in misleading conclusions. To overcome this bottleneck, we propose a robust ensemble approach to classify cells and utilize a batch correction method between reference and query data. We simulated four scenarios that comprise simple to complex batch effect and account for varying cell-type proportions. We further tested our approach on both lung and pancreas data. We found improved prediction accuracy and robust performance across simulation scenarios and real data. The incorporation of batch effect correction between reference and query, and the ensemble approach improve cell-type prediction accuracy while maintaining robustness. We demonstrated these through simulated and real scRNA-Seq data.

description: Symbiotic microbes are commonly found associated in higher organisms, and often have evolved to play an important role in host biology. Researchers have been studying the effects that microbial symbionts have on host physiology, their effects on host nutrition or protection against pathogenic microbial infections, but have recently begun to examine how they influence the brain and behaviour. Wolbachia pipientis, a gram-negative alpha-proteobacteria, intracellular bacterial symbiont infects approximately 40% of all insect species, including Drosophila. The fruit fly, Drosophila melanogaster, one of the most intensively studied organisms in biology and serves as a model system for the investigation of many developmental and cellular processes common to higher eukaryotes, and is naturally infected by several strains of Wolbachia. While Wolbachia are known to infect numerous host tissues, including the brain, little research has focused on how Wolbachia affects the nervous system and behaviour of its host, despite the impact behaviour has on host fitness.

description: Purpose: Multiple methods have been suggested for quantifying syntactic complexity in speech. We compared eight automated syntactic complexity metrics to determine which best captured verified syntactic differences between old and young adults.Method: We used natural speech samples produced in a picture description task by younger (n = 76, ages 18–22 years) and older (n = 36, ages 53–89 years) healthy participants, manually transcribed and segmented into sentences. We manually verified that older participants produced fewer complex structures. We developed a metric of syntactic complexity using automatically extracted syntactic structures as features in a multidimensional metric. We compared our metric to seven other metrics: Yngve score, Frazier score, Frazier–Roark score, developmental level, syntactic frequency, mean dependency distance, and sentence length. We examined the success of each metric in identifying the age group using logistic regression models. We repeated the analysis with automatic transcription and segmentation using an automatic speech recognition (ASR) system.Results: Our multidimensional metric was successful in predicting age group (area under the curve [AUC] = 0.87), and it performed better than the other metrics. High AUCs were also achieved by the Yngve score (0.84) and sentence length (0.84). However, in a fully automated pipeline with ASR, the performance of these two metrics dropped (to 0.73 and 0.46, respectively), while the performance of the multidimensional metric remained relatively high (0.81).Conclusions: Syntactic complexity in spontaneous speech can be quantified by directly assessing syntactic structures and considering them in a multivariable manner. It can be derived automatically, saving considerable time and effort compared to manually analyzing large-scale corpora, while maintaining high face validity and robustness.Supplemental Material S1.

description: In this paper, we consider the contracting curvature flow of smooth closed surfaces in $3$-dimensional hyperbolic space and in $3$-dimensional sphere. In the hyperbolic case, we show that if the initial surface $M_0$ has positive scalar curvature, then along the flow by a positive power $α$ of the mean curvature $H$, the evolving surface $M_t$ has positive scalar curvature for $t>0$. By assuming $α\in [1,4]$, we can further prove that $M_t$ contracts a point in finite time and become spherical as the final time is approached. We also show the same conclusion for the flows by powers of scalar curvature and by powers of Gauss curvature provided that the power $α\in [1/2,1]$. In the sphere case, we show that the flow by a positive power $α$ of mean curvature contracts strictly convex surface in $\mathbb{S}^3$ to a round point in finite time if $α\in [1,5]$. The same conclusion also holds for the flow by powers of Gauss curvature provided that the power $α\in [1/2,1]$.

description: We present the first results of the Chandra and optical follow-up observations of hard X-ray sources detected in the ASCA Medium Sensitivity Survey (AMSS). Optical identifications are made for five objects. Three of them show either weak or absent optical narrow emission lines and are at low redshift ~0.06. One of them is a broad line object at z=0.910 and one is a z=0.460 object with only narrow lines. All the narrow line objects show strong evidence for absorption in their X-ray spectra. Their line ratios are consistent with a Seyfert II/LINER identification as are the line widths. The three low redshift objects have the colors of normal galaxies and apparently the light is dominated by stars. This could be due to the extinction of the underlying nuclear continuum by the same matter that absorbs X-rays and/or due to the dilution of the central source by starlight. These results suggest that X-ray sources that appear as ``normal'' galaxies in optical and near-IR bands significantly contribute to the hard X-ray background. This population of objects has a high space density and probably dominates the entire population of active galaxies.

description: Countries around the world, both developed and emerging, agree that financial literacy education (FLE) is of critical importance, with current economic times having led to an opportune moment for financial education. The 2008 global financial crisis (GFC), increasingly complex financial markets, and widespread growth of alternative or predatory financial services are all valid reasons for FLE. At present FLE is considered an essential 21st century life skill for individuals to acquire. Opportunities to teach individuals how to make simple financial decisions about money management and exposure to financial dilemmas an individual might face are some of the approaches used. Ensuring that individuals manage their personal finances effectively so that they have adequate funds to enable a comfortable retirement tends to be the dominating push of FLE. Indeed, this conventional FLE approach is often packaged as easy to acquire skills and knowledge that individuals are expected to follow to effectively manage their finances. The conventional approach also operates from a deficit perspective where assumptions are made about what an individual can or cannot do based on their financial circumstances. Moreover, the social structures that exist to ensure that both poverty and extreme wealth co-exist are not exposed. Therefore, caution should be taken when viewing education as the sole solution to the world’s economic problems as there are other factors to consider such as socio-economic status (SES), gender, culture and behaviour.

description: We discuss the effects of finite perturbations in fully developed turbulence by introducing a measure of the chaoticity degree associated to a given scale of the velocity field. This allows one to determine the predictability time for non-infinitesimal perturbations, generalizing the usual concept of maximum Lyapunov exponent. We also determine the scaling law for our indicator in the framework of the multifractal approach. We find that the scaling exponent is not sensitive to intermittency corrections, but is an invariant of the multifractal models. A numerical test of the results is performed in the shell model for the turbulent energy cascade.

description: We study the properties of $\hat{Q}[ω]$ operator on the kinematical Hilbert space ${\cal H}$ for canonical quantum gravity. Its complete spectrum with respect to the spin network basis is obtained. It turns out that $\hat{Q}[ω]$ is diagonalized in this basis, and it is a well defined self-adjoint operator on ${\cal H}$. The same conclusions are also tenable on the SU(2) gauge invariant Hilbert space with the gauge invariant spin network basis.

description: This article shows that every non-isotropic harmonic 2-torus in complex projective space factors through a generalised Jacobi variety related to the spectral curve. Each map is composed of a homomorphism into the variety and a rational map off it. The same ideas allow one to construct (pluri)-harmonic maps of finite type from Euclidean space into Grassmannians and the projective unitary groups. Further, some of these maps will be purely algebraic. For maps into complex projective space the algebraic maps of the plane are always doubly periodic i.e. they yield 2-tori. The classification of all these algebraic maps remains open.

Theta functions and Hodge numbers of moduli spaces of sheaves on rational surfaces
Creators: name: Goettsche, Lothar
Publisher: name: arXiv
Year: 1998
Subjects: subject: Algebraic Geometry (math.AG)
subject: FOS: Mathematics

description: Let (S,H) be a rational algebraic surface with an ample divisor. We compute generating functions for the Hodge numbers of the moduli spaces of H-stable rank 2 sheaves on S in terms of certain theta functions for indefinite lattices that were introduced in the paper alg-geom/9612020 written jointly with Don Zagier. If H lies in the closure of the ample cone and has self-intersection 0, it follows that the generating functions are Jacobi forms. In particular the generating functions for the Euler numbers have a similar transformation behaviour under SL(2,Z) as that predicted in Vafa and Witten: A strong coupling test of S-duality. In addition we get that also the generating functions for the signatures can be expressed in terms of modular forms. Finally it turns out that the generating function for the signatures is also (with respect to another developping parameter) the generating function for the Donaldson invariants of S evaluated on all powers of the point class. The paper is related to the recent papers math.AG/9805003 by Yoshioka, math.AG/9805054 and math.AG/9805055 by Qin and Li and hep-th/9802168 by Minahan, Nemeschansky, Vafa and Warner.

description: In this paper, we have tried to apply the concepts of fuzzy sets to Lie groups and its relative concepts. First, we define a $C^1-$fuzzy submanifold after reviewing $C^1-$Fuzzy manifold definition. In main section, we defined the Lie group and some its relative concepts such as fuzzy transformation group, fuzzy G-invariant. Our aim is to prepare the suitable conditions for defining fuzzy differential invariant by constructing suitable objects.
A decision-support method for information inconsistency resolution in direct modeling of CAD models

description: Direct modeling is a very recent CAD paradigm that can provide unprecedented modeling flexibility. It, however, lacks the parametric capability, which is indispensable to modern CAD systems. For direct modeling to have this capability, an additional associativity information layer in the form of geometric constraint systems needs to be incorporated into direct modeling. This is no trivial matter due to the possible inconsistencies between the associativity information and geometry information in a model after direct edits. The major issue of resolving such inconsistencies is that there often exist many resolution options. The challenge lies in avoiding invalid resolution options and prioritizing valid ones. This paper presents an effective method to support the user in making decisions among the resolution options. In particular, the method can provide automatic information inconsistency reasoning, avoid invalid resolution options completely, and guide the choice among valid resolution options. Case studies and comparisons have been conducted to demonstrate the effectiveness of the method.

description: While time series momentum is a well-studied phenomenon in finance, common strategies require the explicit definition of both a trend estimator and a position sizing rule. In this paper, we introduce Deep Momentum Networks -- a hybrid approach which injects deep learning based trading rules into the volatility scaling framework of time series momentum. The model also simultaneously learns both trend estimation and position sizing in a data-driven manner, with networks directly trained by optimising the Sharpe ratio of the signal. Backtesting on a portfolio of 88 continuous futures contracts, we demonstrate that the Sharpe-optimised LSTM improved traditional methods by more than two times in the absence of transactions costs, and continue outperforming when considering transaction costs up to 2-3 basis points. To account for more illiquid assets, we also propose a turnover regularisation term which trains the network to factor in costs at run-time.

Understanding Basic Concepts of Topological Insulators Through Su-Schrieffer-Heeger (SSH) Model

description: Topological insulators are a new class of materials that have attracted significant attention in contemporary condensed matter physics. They are different from the regular insulators and they display novel quantum properties that also involve the idea of `topology', an area of mathematics. Some of the fundamental ideas behind the topological insulators, particularly in low-dimensional condensed matter systems such as poly-acetylene chains, can be understood using a simple one-dimensional toy model popularly known as the Su-Schrieffer-Heeger model or the SSH model. This model can also be used as an introduction to the topological insulators of higher dimensions. Here we give a concise description of the SSH model along with a brief review of the background physics and attempt to understand the ideas of topological invariants, edge states, and bulk-boundary correspondence using the model.

description: Propp and Wilson's method of coupling from the past allows one to efficiently generate exact samples from attractive statistical distributions (e.g., the ferromagnetic Ising model). This method may be generalized to non-attractive distributions by the use of summary states, as first described by Huber. Using this method, we present exact samples from a frustrated antiferromagnetic triangular Ising model and the antiferromagnetic q=3 Potts model. We discuss the advantages and limitations of the method of summary states for practical sampling, paying particular attention to the slowing down of the algorithm at low temperature. In particular, we show that such a slowing down can occur in the absence of a physical phase transition.
