description: Understanding $\textit{galaxy bias}$ -- that is the statistical relation between matter and galaxies -- is of key importance for extracting cosmological information from galaxy surveys. While the bias function $f$ -- that is the probability of forming galaxy in a region with a given density field -- is usually approximated through a parametric expansion, we show here, that it can also be measured directly from simulations in a non-parameteric way. Our measurements show that the Lagrangian bias function is very close to a Gaussian for halo selections of any mass. Therefore, we newly introduce a Gaussian bias model with several intriguing properties: (1) It predicts only strictly positive probabilities $f > 0$ (unlike expansion models), (2) It has a simple analytic renormalized form and (3) It behaves gracefully in many scenarios where the classical expansion converges poorly. We show that the Gaussian bias model describes the galaxy environment distribution $p(δ| \mathrm{g})$, the scale dependent bias function $f$ and the renormalized bias function $F$ of haloes and galaxies generally equally well or significantly better than a second order expansion with the same number of parameters. We suggest that a Gaussian bias approach may enhance the range of validity of bias schemes where the canonical expansion converges poorly and further, that it may make new applications possible, since it guarantees the positivity of predicted galaxy densities.

description: We present a hybrid scheme for quantum computation that combines the modular structure of elementary building blocks used in the circuit model with the advantages of a measurement-based approach to quantum computation. We show how to construct optimal resource states of minimal size to implement elementary building blocks for encoded quantum computation in a measurement-based way, including states for error correction and encoded gates. The performance of the scheme is determined by the quality of the resource states, where within this error model we find a threshold of the order of 10% local noise per particle for fault-tolerant quantum computation and quantum communication.

Notes on Certain Ordovician Faunas of the Inyo Mountains, California
Creators: name: Phleger, Fred B.
Publisher: name: California Institute of Technology
Year: 1932
Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences
subject: Paleontology

description: The Inyo range is situated in east central California. It is bordered on the west by Owens valley and on the east by Deep Spring and Saline valleys. The range trends northwest-southeasterly, and is separated on the south from the Coso mountains by a broad depression east of Olancha. Mount Montgomery is its northern extremity. Together with the White mountains, a term now restricted to the northern portion of the range, the Inyos are about 110 miles in length. The average elevation is about 10,000 feet.

The sedimentary rocks of the range have a total thickness of more than 36,000 feet, with every system from the pre-Cambrian to the Jurassic, excepting the Silurian, represented. Structurally, the sedimentary rocks from a broad, low anticline flanked on the west by a complemental syncline, both of which strike to the northwest and plunge to the southeast. Southwardly the stratigraphic position of the rocks exposed becomes successively higher, with the pre-Cambrian outcropping in the north and the Jurassic in the south. This simple structure has been modified by complex faulting.

During the fall of 1931 the writer spent several day in the Inyo range with Dr. John H. Bradley, Jr. collecting fossils, and it was at his suggestion that the present study was begun. The field work was continued during the following winter and spring.

The purpose of this paper is to describe the faunas and stratigraphy of the Barrel Springs and Mazourka formations of Ordovician age as exposed in the Inyo range north and east of Independence, California.

description: Bicycle infrastructure networks must meet the needs of cyclists to position cycling as a viable transportation choice in cities. In particular, protected infrastructure should be planned cohesively for the whole city and spacious enough to accommodate all cyclists safely and prevent cyclist congestion -- a common problem in cycling cities like Copenhagen. Here, we devise an adaptive method for optimal bicycle network design and for evaluating congestion criticalities on bicycle paths. The method goes beyond static network measures, using computationally efficient adaptation rules inspired by Optimal Transport on the dynamically updating multilayer network of roads and protected bicycle lanes. Street capacities and cyclist flows reciprocally control each other to optimally accommodate cyclists on streets with one control parameter that dictates the preference of bicycle infrastructure over roads. Applying our method to Copenhagen confirms that the city's bicycle network is generally well-developed. However, we are able to identify the network's bottlenecks, and we find, at a finer scale, disparities in network accessibility and criticalities between different neighborhoods. Our model and results are generalizable beyond this particular case study to serve as a scalable and versatile tool for aiding urban planners in designing cycling-friendly cities.

description: We describe a measurement method that enables the correct estimation of the charging energy of an unintentional quantum dot (QD) in the channel of a metal-oxide-semiconductor field-effect transistor (MOSFET). If the channel has a dominant QD with a large charging energy and an array of stray QDs with much weaker charging, this method eliminates the additional voltage drops due to stray QDs by regarding the stray QDs as series resistors. We apply this method to a short-channel MOSFET and find that the charging energy of the dominant QD can indeed be smaller than the size of the Coulomb diamond.

Literatura española en exposición. Fráncfort 2022 y las maniobras de “desbordamiento” del canon
Creators: name: Anastasio, Matteo
Publisher: name: Estudios Culturales Hispánicos
Year: 2024

description: El artículo analiza las imágenes propuestas por la exhibición de España en su segunda participación como país invitado de honor en la Feria del Libro de Fráncfort de 2022, concentrándose en la cohesión entre el programa de España, en los discursos que este produjo sobre la literatura, y la estética del pabellón y su exposición literaria. La obra de promoción del país invitado de 2022, que contrasta con la primera participación de España en 1991, apuntó a proyectar valores como la igualdad de géneros, la diversidad y pluralidad lingüística como marcas distintivas de una “nueva literatura española”. La construcción de este perfil identitario, que se refleja en los distintos niveles de su puesta en escena, lleva consigo en parte también dimensiones contrapuestas, frente al objetivo de la valoración del castellano como idioma nacional y global. El presente trabajo investiga de forma crítica la construcción retórica, visual, plástica y performativa de este perfil y sus intentos de revisión o deconstrucción de horizontes canónicos tradicionales y sus funcio­nes simbólicas.


This paper analyses the images projected by Spain’s exhibition in its second participation as guest of honour at the Frankfurt Book Fair 2022, focusing on the consistency of its program in the discursive and aesthetics dimensions of its strategies and literary display in its pavilion. The promotional work of the guest country in 2022, which contrasts with Spain’s first participation in 1991, aimed to project values such as gender equality, diversity and linguistic plurality as distinguishing marks of a “new Spanish litera­ture”. The construction of this identity profile, which is reflected in selections at different levels of its staging, also carries with it conflicting dimensions, against other goals such as the promotion of Castilian as both national and global language. This paper critically in­vestigates the construction of this profile at visual, rhetorical, plastic and performative levels and its attempts to revise or deconstruct traditional canonical horizons and their symbolic functions.

La percepción de España como país invitado de honor en la Feria del Libro de Fráncfort de 2022. Resultados de una encuesta entre el público y unas observaciones breves acerca de la quimera de la diversidad cultural

Publisher: name: Estudios Culturales Hispánicos

description: Entre 2017 y 2022 realizamos más de 1.400 entrevistas con visitantes de la Feria del Libro de Fráncfort que siempre implicaban preguntas con respecto a los así llamados países invitados. En este artículo, contrastamos los resultados del año 2022, con España como país invitado, con aquellos de las ediciones anteriores. Se observan dos fe­nómenos: primero, el público alemán lee menos libros de autores españoles en compara­ción con autores de otros países. Segundo, existe una discrepancia entre la programación española oficial en la feria y las expectativas por parte del público acerca de la representa­ción de las literaturas minoritarias de la Península, por un lado, y de las literaturas hispa­noamericanas, por el otro. Así, se concluye que el énfasis retórico en la diversidad cultural de España y de la lengua española, asumido por el comité organizador, poco repercutió en el evento.


Between 2017 and 2022, we conducted more than 1,400 interviews with visi­tors to the Frankfurt Book Fair, which always involved questions regarding the so-called guest of honour. In this article, we contrast the results of the year 2022, with Spain as the guest of honour, to those of previous editions. Two phenomena are observed: first, the German public reads fewer books written by Spanish authors compared to those of authors from other countries. Second, there is a discrepancy between the official Spanish pro­gramme at the fair and the public's expectations regarding the representation of minority literatures from the Peninsula on the one hand, and Spanish-American literatures on the other. Thus, it is concluded that the rhetorical emphasis on the cultural diversity of Spain and the Spanish language, assumed by the organising committee, had little impact on the event.

Constraints on long-lived remnants of neutron star binary mergers from late-time radio observations of short duration gamma-ray bursts
Creators: name: Metzger, Brian D.

Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The coalescence of a binary neutron star (NS) system may in some cases produce a massive NS remnant that is long-lived and, potentially, indefinitely stable to gravitational collapse. Such a remnant has been proposed as an explanation for the late X-ray emission observed following some short duration gamma-ray bursts (GRBs) and as possible electromagnetic counterparts to the gravitational wave chirp. A stable NS merger remnant necessarily possesses a large rotational energy > 1e52 erg, the majority of which is ultimately deposited into the surrounding circumburst medium (CBM) at mildly relativistic velocities. We present Very Large Array radio observations of 7 short GRBs, some of which possessed temporally extended X-ray emission, on timescales of ~1-3 years following the initial burst. No radio sources were detected, with typical upper limits ~0.3 mJy at 1.4 GHz. A basic model for the synchrotron emission from the blast wave is used to constrain the presence of a long-lived NS merger remnant in each system. Depending on the GRB, our non-detections translate into upper limits on the CBM density n < 3e-2 - 3e-3 particles/cm^3 required for consistency with the remnant hypothesis. Our upper limits rule out a long-lived remnant in GRB 050724 and 060505, but cannot rule out such a remnant in other systems due to their lower inferred CBM densities based on afterglow modeling or the lack of such constraints. Additional VLA observations in the near future could place tighter limits on the presence of merger remnants in these system. The population of long-lived NS merger remnants will also be constrained by their (non-)detection with upcoming radio transient surveys.

description: A calibration procedures of the Default Correlation model is presented. There are two principal modifications. The first is to change the manner in which asset correlations are converted into default correlations, the second is a small change in the algorithm by which the probability equations of the model are solved. These changes are considered appropriate, and are necessary for the model to be considered robust enough to underpin the structuring and trading of complex credit contingent instruments.

Rodents and Lagomorphs of the Carpinteria Asphalt
Creators: name: Wilson, Robert Warren
Publisher: name: California Institute of Technology
Year: 1932
Subjects: subject: Geology
subject: FOS: Earth and related environmental sciences
subject: Paleontology

description: Plant and animal remains were first discovered in the Carpinteria asphalt deposits on the Higgins Ranch near the town of Carpinteria early in 1927. A preliminary announcement of the occurrence was published by Hoffman, Stock, and Chaney.(1927) Since then more detailed work carried on at the locality has furnished additional and larger collections of bird and mammal material. While the bird assemblage has been determined by Loye Miller(1931)
and by Alden Miller(1932:), no very complete set of the mammals is as yet available. The present study embodies a critical determination of the various rodent and rabbit types occurring in the fauna with a view to establishing evidence of value in an interpretation of the age relationships of the deposits and of the environmental conditions under which the mammalian fauna existed. The problem was suggested by Doctor Chester Stock of the California Institute of Technology to whom the author is indebted for guidance during the course of the investigation and for criticism of the manuscript.

The author also wishes to thank the staff of the late Mr. Donald R. Dickey at the California Institute of Technology for their courtesy in permitting tree use of their collections of Recent mammals.
Gradient sensing limit of a cell when controlling the elongating direction

name: Kobayashi, Tetsuya J.
Publisher: name: arXiv
Year: 2024
Subjects: subject: Cell Behavior (q-bio.CB)
subject: FOS: Biological sciences

description: Eukaryotic cells perform chemotaxis by determining the direction of chemical gradients based on stochastic sensing of concentrations at the cell surface. To examine the efficiency of this process, previous studies have investigated the limit of estimation accuracy for gradients. However, these studies assume that the cell shape and gradient are constant, and do not consider how adaptive regulation of cell shape affects the estimation limit. Dynamics of cell shape during gradient sensing is biologically ubiquitous and can influence the estimation by altering the way the concentration is measured, and cells may strategically regulate their shape to improve estimation accuracy. To address this gap, we investigate the estimation limits in dynamic situations where cells change shape adaptively depending on the sensed signal. We approach this problem by analyzing the stationary solution of the Bayesian nonlinear filtering equation. By applying diffusion approximation to the ligand-receptor binding process and the Laplace method for the posterior expectation under a high signal-to-noise ratio regime, we obtain an analytical expression for the estimation limit. This expression indicates that estimation accuracy can be improved by elongating perpendicular to the estimated direction, which is also confirmed by numerical simulations. Our analysis provides a basis for clarifying the interplay between estimation and control in gradient sensing and sheds light on how cells optimize their shape to enhance chemotactic efficiency.

description: In a model that supports both Abelian (Abrikosov-Nielsen-Olesen) and non-Abelian strings we analyze the parameter space to find examples in which these strings not only coexist but are degenerate in tension. We prove that both solutions are locally stable, i.e there are no negative modes in the string background. The tension degeneracy is achieved at the classical level and is expected to be lifted by quantum corrections. The set up of the model, analogous to that of Witten's superconducting cosmic strings, had been extended to include non-Abelian strings.

description: We report the synthesis and properties of (H,Li)$_{6}$Ru$_{2}$O$_{6}$, which is shown to be a $J_{\text{eff}}=\frac{1}{2}$ system made out of Ru$^{3+}$ moments in a honeycomb geometry. Bulk magnetization, heat capacity, nuclear magnetic resonance (NMR), and muon spin relaxation ($μ$SR) rule out the presence of static moments or any spin glass phase down to 84 mK. All techniques suggest a crossover to a liquid-like state below about 40 K. The $^{7}$Li nuclear magnetic resonance (NMR) shift data suggest a non-zero $T$-independent spin susceptibility at low $T$. In zero field, $C_m/T$ shows $T^{-0.9}$ divergence which is consistent with vacancy-induced effects on low-energy excitations of the pristine Kitaev spin liquid. With field, power-law variations in the $^{7}$Li NMR spin-lattice relaxation rate 1/T$_{1}$ and magnetic heat capacity $C_{m}$ show quantitatively new scaling behaviors. A two-step entropy release in heat capacity is also observed putatively from $Z_{2}$ flux (low-$T$ step) and itinerant Majorana fermions (high-$T$ step). Based on these findings, we propose that (H,Li)$_{6}$Ru$_{2}$O$_{6}$ realizes a Kitaev spin liquid with no evidence of inherent magnetic ordering in zero field unlike $α$-RuCl$_{3}$ where approximately $8$ Tesla field is required to suppress magnetic order.

description: The purpose of this study was to investigate associations between, and within, drop jump (DJ) neuromuscular performance (NMP) qualities and maximal horizontal deceleration ability. We also compared DJ NMP qualities in “high” versus “low” horizontal deceleration ability athletes. Twenty-nine university athletes performed: (1) DJs on force plates from 20 (DJ20) and 40 cm (DJ40) heights and (2) maximal horizontal deceleration, measured using radar, following a 20 m acceleration. Maximal horizontal deceleration was evaluated using deceleration (HDEC; m·s−2 ), across the entire deceleration phase and during early and late deceleration sub-phases. Of the DJ variables assessed, DJ20 and DJ40 reactive strength index (RSI) and concentric mean force had the largest correlations with HDEC (r = −0.54 to −0.61) and the largest differences between high and low HDEC groups (d = 1.20 to 1.40). These correlations were stronger with the early than late HDEC sub-phase (r = −0.54 to −0.66 vs. r = −0.24 to −0.40). Notably, eccentric mean force in DJ40 had large correlations with both DJ20 and DJ40 concentric mean force (r = 0.67 to 0.77), whereas at DJ20 these correlations were small (r = 0.22 to 0.40). Similarly, DJ40 eccentric mean force had a much larger difference between the high and low HDEC groups than DJ20 (d = 1.11 vs. 0.51). These findings suggest DJ RSI from either height may be used as a proxy for HDEC ability, while DJ kinetic analyses should use a higher height to distinguish those with a better capacity to generate eccentric braking forces under increased eccentric loading demands.

Most existing approaches generate augmented views of the same user sequence through random augmentation and subsequently maximize their agreement in the representation space. However, these methods often neglect the rationality of the augmented samples. Due to significant uncertainty, random augmentation can disrupt the semantic information and interest evolution patterns inherent in the original user sequences. Moreover, pulling semantically inconsistent sequences closer in the representation space can render the user sequence embeddings insensitive to variations in user preferences, which contradicts the primary objective of sequential recommendation. To address these limitations, we propose the Context-aware Diffusion-based Contrastive Learning for Sequential Recommendation, named CaDiRec. The core idea is to leverage context information to generate more reasonable augmented views. Specifically, CaDiRec employs a context-aware diffusion model to generate alternative items for the given positions within a sequence. These generated items are aligned with their respective context information and can effectively replace the corresponding original items, thereby generating a positive view of the original sequence. By considering two different augmentations of the same user sequence, we can construct a pair of positive samples for contrastive learning. To ensure representation cohesion, we train the entire framework in an end-to-end manner, with shared item embeddings between the diffusion model and the recommendation model. Extensive experiments on five benchmark datasets demonstrate the advantages of our proposed method over existing baselines.

Colored scalars and the neutron electric dipole moment

description: We investigate new contributions to the neutron electric dipole moment induced by colored scalars. As an example, we evaluate contributions coming from the color octet, weak doublet scalar, accommodated within a modified Minimal Flavor Violating framework. These flavor non-diagonal couplings of the color octet scalar might account for the $A_{CP} (D^0 \to K^- K^+) - A_{CP} (D^0 \to π^+ π^-)$ asymmetry on the tree level. Using these charm asymmetry constrained couplings, we calculate two-loop contributions to the neutron electric dipole moment and find that they are of the same order as the experimental bound. We comment also on contributions of higher dimensional operators to the neutron electric dipole moment within this framework.

description: Museums have undergone a tremendous digital transformation, and as they enter their post-digital era, more comprehensive use of digital technology by museums can be expected. An approach to evaluating digital project development on a strategic and sustainable level must therefore be explored. In the meantime, the reconceptualization of the relationship between museums and the public provides a turning point for museums to rethink and adjust their visitor research in order to develop digital technology initiatives for one of their target audiences - school groups - in collaboration with schools to better achieve museums' educational missions. To obtain a comprehensive understanding of how museums design and develop digital technologies for educational purposes, a systematic evaluation of museum digital technology is proposed. This study focuses on the national science and technology museums in Taiwan, with the aim of exploring the user experience of three museum digital technologies among secondary school students. A user experience questionnaire survey was conducted among 178 students to obtain their feedback on three digital technologies. Additionally, five semi-structured interviews were conducted with museum digital technology developers to identify their design process and potential challenges in digital technology development and evaluation. Lastly, this research employed a Delphi survey, involving a panel of 23 museum staff and 24 schoolteachers, to identify 56 variables and 5 dimensions for evaluating museum digital technology. By utilizing this methodology, this study aimed to provide a comprehensive evaluation of museum digital technology that can inform future design and development efforts. The research proposes a conceptual tool that integrates a series of experiencerelated, content-related, and design-related elements that are located at three levels subjective, strategic, and sustainable – of developing museum digital technology for school groups. The 3S Museum Digital Technology Evaluation Model incorporates the perspectives of students, schoolteachers, museum employees, and museum digital technology developers with diverse requirements, skills, and prior knowledge, which can play an important role in enabling the development of museum digital technology with a higher quality user experience for school groups.

description: Frequency-multiplexing is an effective method to achieve resource-efficient superconducting qubit readout. Allowing multiple resonators to share a common feedline, the number of cables and passive components involved in the readout of a qubit can be drastically reduced. However, this improvement in scalability comes at the price of a crucial non-ideality -- an increased readout crosstalk. Prior works have targeted building better devices and discriminators to reduce its effects, as readout-crosstalk-induced qubit measurement errors are detrimental to the reliability of a quantum computer. However, in this work, we show that beyond the reliability of a system, readout crosstalk can introduce vulnerabilities in a system being shared among multiple users. These vulnerabilities are directly related to correlated errors due to readout crosstalk. These correlated errors can be exploited by nefarious attackers to predict the state of the victim qubits, resulting in information leakage.

description: In a finite one-dimensional non-Hermitian system, the number of zero modes does not necessarily reflect the topology of the system. This is known as the breakdown of the bulk-boundary correspondence and has led to misconceptions about the topological protection of edge modes in such systems. Here we show why this breakdown does occur and that it typically results in hidden zero modes, extremely long-lived zero energy excitations, which are only revealed when considering the singular value instead of the eigenvalue spectrum. We point out, furthermore, that in a finite multiband non-Hermitian system with Hamiltonian $H$, one needs to consider also the reflected Hamiltonian $\tilde H$, which is in general distinct from the adjoint $H^\dagger$, to properly relate the number of protected zeroes to the winding number of $H$.

description: Faint fuzzies are metal-rich apparently-old star clusters with unusually large radii (7-15 pc), found mostly in S0 galaxies, whose source remain obscure. To identify their origins, we compare planetary nebulae and neutral hydrogen with faint fuzzy positions and line-of-sight velocities in NGC1023. In this way, we rule out scenarios in which these objects are associated with an on-going merger or with a spheroid population in NGC1023. Their kinematics are indistinguishable from the stellar disk population in this galaxy, and we conclude that faint fuzzies are most likely just remnant open clusters. Their observed association with S0s then simply reflects the difficulty of identifying such objects in later-type disk galaxies.

description: The search for strongly inversion asymmetric topological insulators is an active research field because these materials possess distinct properties compared with the inversion symmetric ones. In particular, it is desirable to realize a large Rashba spin-splitting (RSS) in such materials, which combined with the topological surface states (TSS) could lead to useful spintronics applications. In this report, based on first principles calculations, we predict that the heterostructure of BiTeI/Bi$_{2}$Te$_{3}$ is a strong topological insulator with a giant RSS. The coexistence of TSS and RSS in the current system is native and stable. More importantly, we find that both the $\mathbb{Z}_{2}$ invariants and the Rashba energy can be controlled by engineering the layer geometries of the heterostructure, and the Rashba energy can be made even larger than that of bulk BiTeI. Our work opens a new route for designing topological spintronics devices based on inversion asymmetric heterostructures.

description: Future smart grids can and will be subject of systematic attacks that can result in monetary costs and reduced system stability. These attacks are not necessarily malicious, but can be economically motivated as well. Emerging flexibility markets are of interest here, because they can incite attacks. Since dimension and danger potential of such strategies are still uncertain, analysis tools are required to systematically search for unknown strategies and their respective countermeasures. We propose deep reinforcement learning to learn attack strategies autonomously to identify underlying systemic vulnerabilities this way. Exemplarily, we apply our approach to a reactive power market setting in a distribution grid. In our case study, the attacker learned to exploit the reactive power market by using controllable loads to induce constraint violations into the system and then providing remunerated countermeasures, thus finding a previously unknown economically motivated attack strategy.
