description: For fixed $h \geq 2$, we consider the task of adding to a graph $G$ a set of weighted shortcut edges on the same vertex set, such that the length of a shortest $h$-hop path between any pair of vertices in the augmented graph is exactly the same as the original distance between these vertices in $G$. A set of shortcut edges with this property is called an exact $h$-hopset and may be applied in processing distance queries on graph $G$. In particular, a $2$-hopset directly corresponds to a distributed distance oracle known as a hub labeling. In this work, we explore centralized distance oracles based on $3$-hopsets and display their advantages in several practical scenarios. In particular, for graphs of constant highway dimension, and more generally for graphs of constant skeleton dimension, we show that $3$-hopsets require exponentially fewer shortcuts per node than any previously described distance oracle while incurring only a quadratic increase in the query decoding time, and actually offer a speedup when compared to simple oracles based on a direct application of $2$-hopsets. Finally, we consider the problem of computing minimum-size $h$-hopset (for any $h \geq 2$) for a given graph $G$, showing a polylogarithmic-factor approximation for the case of unique shortest path graphs. When $h=3$, for a given bound on the space used by the distance oracle, we provide a construction of hopsets achieving polylog approximation both for space and query time compared to the optimal $3$-hopset oracle given the space bound.

description: This paper compares the mean and variance of cumulative abnormal returns following announcements of two types of information technology (IT) investments: those which entail the “exploitation” of firm’s current capabilities vs. those which involve the exploration of new capabilities. The paper addresses two understudied questions in research on the contribution of IT to firm performance: the contingent nature of those contributions and the impact on risk (or variance), as well as on return (mean). To examine these questions I first performed a standard event study analysis on a sample of 150 announcements of IT investments made by 59 publicly-traded retailers between the years 1990- 1997. I performed two types of multivariate regression analysis on the event returns: ordinary least squares (to assess the impact of the two types of investments on the mean level of returns) and multiplicative heteroscedastic regression (to determine the impact on the variance of the returns). The results indicate that, as expected, IT investments “exploitative” IT investments have the same mean as, yet lower variance than, abnormal returns associated with “exploratory” IT investments. Somewhat unexpectedly, I found that both types of IT investments had a significantly negative impact on the market value of the firm. Taken together, these findings suggest that the characteristics of IT investments themselves, as well as the industry and strategic context within which they were made, are important determinants of the market value of the firm. As such, the results of this study should be of interest to researchers interested in the contribution of IT to firm performance and to MIS professionals both in the retailing sector, in particular, and other service sectors, more generally.

description: This study uses previous theory developed in the IT implementation literature and the information processing view of the firm to empirically investigate the impact of IT investments and several contextual variables on the volatility of future earnings. We useInformationWeek 500 data on IT spending from 1992–1997 to find evidence that IT investments increase the volatility of future earnings but that this impact is highly contingent upon three firm level contextual factors — sales growth, unrelated diversification, and size. These factors can lead to conditions in which IT increases or reduces earnings volatility. Taken together, these results may help explain what has recently been termed the “new productivity paradox,” i.e., the apparent under-investment in information technology despite evidence of highly positive returns for doing so, and suggests settings where managers may be under- or over-discounting returns on IT investments.

Unlocking the Power of ED2 model on HPC cluster: A Singularity Container Approach

description: The Ecosystem Demography Biosphere Model (ED2[1]) is an open-source, comprehensive terrestrial biosphere model that integrates hydrology, land-surface biophysics, vegetation dynamics, and carbon biogeochemistry. Since its inception in 2001, researchers have utilized this model to examine a variety of tropical and temperate ecosystems over years. 

ED2 presents challenges to new users due to its implementation in Fortran 90 with required HDF5 libraries, necessitating specific prior knowledge. Additionally, running the model over extended periods demands substantial computational resources, complicating deployment across various computing platforms. High Performance Computing (HPC) cluster usage requires prior knowledge about clusters and a learning curve for job submission. To lower these barriers for the broader ecological community, we implemented a Singularity-based containerization of ED2 and developed a Jupyter Notebook to simplify job submissions to HPC clusters.

The containerized version of ED2 can be easily deployed on various High-Performance Computing (HPC) platforms. This container includes the ED2 binary and all necessary libraries, removing the need for additional installations and allowing the capability to "run everywhere." Additionally, the Jupyter notebooks enable users to seamlessly modify model configurations and run the model on both local machines and different HPC clusters. This approach simplifies the process of communicating with the HPC cluster and managing slurm jobs. The notebook also includes features for frequently checking the status of ongoing jobs on the HPC cluster and transferring the output back to the local machine. We have created basic demo visualizations of the output, allowing users to further visualize their results using Python or R as they prefer.

We ran the containerized ED2 model running on the University of Illinois Campus Cluster, TEXAS Stampede clusters and NCSA Delta, analyzing 20 years of model simulations over multiple sites in tropical and temperate ecosystems. We are working towards testing and adding the configuration to run on additional clusters (such as the NASA HEC system). We have held a workshop at the ED2 community meeting at Harvard in 2024 where the ED2 community showed significant interest in the combination of notebooks and containers.

Fine-Grained Object Recognition and Zero-Shot Learning in Remote Sensing Imagery

description: Fine-grained object recognition that aims to identify the type of an object among a large number of subcategories is an emerging application with the increasing resolution that exposes new details in image data. Traditional fully supervised algorithms fail to handle this problem where there is low between-class variance and high within-class variance for the classes of interest with small sample sizes. We study an even more extreme scenario named zero-shot learning (ZSL) in which no training example exists for some of the classes. ZSL aims to build a recognition model for new unseen categories by relating them to seen classes that were previously learned. We establish this relation by learning a compatibility function between image features extracted via a convolutional neural network and auxiliary information that describes the semantics of the classes of interest by using training samples from the seen classes. Then, we show how knowledge transfer can be performed for the unseen classes by maximizing this function during inference. We introduce a new data set that contains 40 different types of street trees in 1-ft spatial resolution aerial data, and evaluate the performance of this model with manually annotated attributes, a natural language model, and a scientific taxonomy as auxiliary information. The experiments show that the proposed model achieves 14.3% recognition accuracy for the classes with no training examples, which is significantly better than a random guess accuracy of 6.3% for 16 test classes, and three other ZSL algorithms.

description: In the spectral density of Cr(001) surfaces a sharp resonance close to the Fermi level is observed in both experiment and theory. For the physical origin of this peak two mechanisms were proposed. A single particle dz2 surface state renormalised by electron-phonon coupling and an orbital Kondo effect due to the degenerate dxz/dyz states. Despite several experimental and theoretical investigations, the origin is still under debate. In this work we address this problem by two different approaches of the dynamical mean-field theory. First, by the spin-polarized T-matrix fluctuation exchange approximation suitable for weakly and moderately correlated systems. Second, by the non-crossing approximation derived in the limit of weak hybridization (i.e. for strongly correlated systems) capturing Kondo-like processes. By using recent continuous-time quantum Monte Carlo calculations as a benchmark, we find that the high-energy features, everything except the resonance, of the spectrum is captured within the spin-polarized T-matrix fluctuation exchange approximation. More precisely the particle-particle processes provide the main contribution. For the non-crossing approximation it appears that spin-polarized calculations suffer from spurious behavior at the Fermi level. Then, we turned to non spin-polarized calculations to avoid this unphysical behavior. By employing two plausible starting hybridization functions, it is observed that the characteristics of the resonance are crucially dependent on the starting point. It appears that only one of these starting hybridizations could result in an orbital Kondo resonance in the presence of a strong magnetic field like in the Cr(001) surface. It is for a future investigation to first resolve the unphysical behavior within the spin-polarized non-crossing approximation and then check for an orbital Kondo resonance.

description: In order to explore the reason why the single-layered cuprates, La$_{2-x}$(Sr/Ba)$_x$CuO$_4$ ($T_c\simeq$ 40K) and HgBa$_2$CuO$_{4+δ}$ ($T_c\simeq$ 90K), have such a significant difference in $T_c$, we study a two-orbital model that incorporates the $d_{z^2}$ orbital on top of the $d_{x^2-y^2}$ orbital. It is found, with the fluctuation exchange approximation, that the $d_{z^2}$ orbital contribution to the Fermi surface, which is stronger in the La system, works against d-wave superconductivity, thereby dominating over the effect of the Fermi surface shape. The result resolves the long-standing contradiction between the theoretical results on Hubbard-type models and the experimental material dependence of $T_c$ in the cuprates.

description: Formal and informal organization structure have been described as “opposing poles of a duality”—one which has yet to be fully resolved. The aim of this paper is to detail an approach to treating both structures in a comparable way, an approach that explicitly recognizes core and underlying commonalties. Two distinct analytical strategies are employed to this end. The first involves a detailed comparison and contrast of selected and relevant structural dimensions drawn from the two research streams. The second strategy involves the application of these dimensions to the study of network graphs of both the formal and informal structures of the same organization at the same point in time.

description: The problem of multilevel diversity coding with secure regeneration (MDC-SR) is considered, which includes the problems of multilevel diversity coding with regeneration (MDC-R) and secure regenerating code (SRC) as special cases. Two outer bounds are established, showing that separate coding of different messages using the respective SRCs can achieve the minimum-bandwidth-regeneration (MBR) point of the achievable normalized storage-capacity repair-bandwidth tradeoff regions for the general MDC-SR problem. The core of the new converse results is an exchange lemma, which can be established using Han's subset inequality.

description: Detection and study of gravitational waves from astrophysical sources is a major goal of current astrophysics. Ground-based laser-interferometer systems such as LIGO and VIRGO are sensitive to gravitational waves with frequencies of order 100 Hz, whereas space-based systems such as LISA are sensitive in the millihertz regime. Precise timing observations of a sample of millisecond pulsars widely distributed on the sky have the potential to detect gravitational waves at nanohertz frequencies. Potential sources of such waves include binary super-massive black holes in the cores of galaxies, relic radiation from the inflationary era and oscillations of cosmic strings. The Parkes Pulsar Timing Array (PPTA) is an implementation of such a system in which 20 millisecond pulsars have been observed using the Parkes radio telescope at three frequencies at intervals of two -- three weeks for more than two years. Analysis of these data has been used to limit the gravitational wave background in our Galaxy and to constrain some models for its generation. The data have also been used to investigate fluctuations in the interstellar and Solar-wind electron density and have the potential to investigate the stability of terrestrial time standards and the accuracy of solar-system ephemerides.

description: We discuss a solar dynamo model of Tayler-Spruit type whose Omega-effect is conventionally produced by a solar-like differential rotation but whose alpha-effect is assumed to be periodically modulated by planetary tidal forcing. This resonance-like effect has its rationale in the tendency of the current-driven Tayler instability to undergo intrinsic helicity oscillations which, in turn, can be synchronized by periodic tidal perturbations. Specifically, we focus on the 11.07 years alignment periodicity of the tidally dominant planets Venus, Earth, and Jupiter, whose persistent synchronization with the solar dynamo is briefly touched upon. The typically emerging dynamo modes are dipolar fields, oscillating with a 22.14 years period or pulsating with a 11.07 years period, but also quadrupolar fields with corresponding periodicities. In the absence of any constant part of alpha, we prove the subcritical nature of this Tayler-Spruit type dynamo. The resulting amplitude of the alpha oscillation that is required for dynamo action turns out to lie in the order of 1 m/s, which seems not implausible for the sun. When starting with a more classical, non-periodic part of alpha, even less of the oscillatory alpha part is needed to synchronize the entire dynamo. Typically, the dipole solutions show butterfly diagrams, although their shapes are not convincing yet. Phase coherent transitions between dipoles and quadrupoles, which are reminiscent of the observed behaviour during the Maunder minimum, can be easily triggered by long-term variations of dynamo parameters, but may also occur spontaneously even for fixed parameters. Further interesting features of the model are the typical second intensity peak and the intermittent appearance of reversed helicities in both hemispheres.

description: We have sought interstellar ethyl-cyanide via its 202–101 transition towards two cold, dark clouds and report upper limits of the total column densities of 3×1012cm–2 and 2×1012cm–2 for TMC-1 and L134N, respectively. We also observed the 202–101 transition of vinyl cyanide previously identified in TMC-1 by Matthews and Sears (1983b). The detection of vinyl cyanide and the non-detection of ethyl cyanide in TMC-1 are consistent with gas phase ion-molecule chemical models, and there is thus no necessity of invoking grain surface synthesis for vinyl cyanide in cold clouds.

description: The Cloud radio access network (C-RAN) offers a revolutionary approach to cellular network deployment, management and evolution. Advances in software-defined radio (SDR) and networking technology, moreover, enable delivering software-defined everything through the Cloud. Resources will be pooled and dynamically allocated leveraging abstraction, virtualization, and consolidation techniques; processes will be automated using common application programming interfaces; and network functions and services will be programmatically provided through an orchestrator. OOCRAN, oocran.dynu.com, is a software framework that is based on the NFV MANO architecture proposed by ETSI. It provides an orchestration layer for the entire wireless infrastructure, including hardware, software, spectrum, fronthaul and backhaul. OOCRAN extends existing NFV management frameworks by incorporating the radio communications layers and their management dependencies. The wireless infrastructure provider can then dynamically provision virtualized wireless networks to wireless service providers. The testbed's physical infrastructure is built around a computing cluster that executes open-source SDR libraries and connects to SDR-based remote radio heads. We demonstrate the operation of OOCRAN and discuss the temporal implications of dynamic LTE small cell network deployments.

Our analytical approach involves an examination of discourse about Napster in several arenas—legal, economic, social, and cultural—and is informed by a conceptualization of Napster as an ongoing encounter between, rather than the accomplishment of, inventor(s), institution(s), and interest(s). While we recognize the value of empirical examinations of Napster's impact on firms and markets, as well as the proscriptive advice which it supports, we opt here for providing a contextualized understanding of the technology that complements rather than substitutes for empirical analyses of it.

description: he capacity to efficiently manage the whole set of resources from the edge up to the cloud paves the way to a new landscape of innovative opportunities for all involved actors, be it on the research or industrial sides. Some existing efforts are already focusing on designing a management system addressing the different challenges posed by such scenario. Fog-to-Cloud (F2C) has been recently proposed as a management solution particularly tailored to manage the stack of resources from the edge to cloud in a coordinated way. However, beyond the benefits brought by considering all the spectrum of resources to run a service, resilience, as a concept must be reflected in the F2C design. In this paper, we address a particular scenario where a specific node failure in the F2C architecture will substantially impact on the whole system performance. Three tentative strategies are proposed to efficiently manage the database hand over in the considered F2C failure scenario, that are preliminary analyzed in a simulated scenario.

description: Much of the literature linking organization structure to performance falls into two broad research streams. One stream concerns formal structure – the hierarchy of authority or reporting relationships as well as the degree of standardization, formalization, specialization, etc. The impact of formal structure and other elements of organization design on performance is typically contingent on factors such as strategic orientation, task characteristics, and environmental conditions. The other research stream focuses on informal structure – a network of interpersonal and intra-organizational relationships. Properties of informal structure are typically shown to have a more direct (less contingent) impact on organizational performance. Despite these pronounced differences in the conceptualization of organization structure, considerable overlap and complementarity exist between the two research streams. In this article, I compare and contrast a pair of exemplars from each stream – the information processing perspective and the social network perspective – with respect to their conceptualizations of organization structure and its relationship to performance. Several recommendations for future research that combines the two approaches are offered.

description: We present late-time optical spectroscopy and X-ray, UV, and optical photometry of the nearby ($d=214$ Mpc, $z=0.0479$) tidal disruption event (TDE) ASASSN-15oi. The optical spectra span 450 days after discovery and show little remaining transient emission or evolution after roughly 3 months. In contrast, the Swift and XMM-Newton observations indicate the presence of evolving X-ray emission and lingering thermal UV emission that is still present 600 days after discovery. The thermal component of the X-ray emission shows a unique, slow brightening by roughly an order of magnitude to become the dominant source of emission from the TDE at later times, while the hard component of the X-ray emission remains weak and relatively constant throughout the flare. The TDE radiated $(1.32\pm0.06)\times10^{51}$ ergs across all wavelengths, and the UV and optical emission is consistent with a power law decline and potentially indicative of a late-time shift in the power-law index that could be caused by a transition in the dominant emission mechanism.

Making sense of father-son estrangement

distancing

description: This narrative study explores how five adult sons of varying ages make sense of their estrangement from their fathers. In semi-structured interviews, the men explained how their estrangements came about and what significance they have had in their lives. An ideographic narrative analysis reveals the diversity of the men’s stories. The accounts are then discussed with reference to the emerging estrangement literature and to understandings of narrative constructions of self based on power and agency, intimacy and separation. The study finds that recent theorising helps to illuminate some aspects of the accounts, notably the role played by physical distance, and paternal anger and indifference. However, some accounts are not well reflected in previous characterisations of parent-child estrangement; in particular the emphasis on distancing by adult children is somewhat incongruous with the narratives of paternal distancing. The study further concludes that, while the sons regret their father’s inability to connect, some construe the distance from him as an opportunity for agency and personal growth.

description: In the first week of December 2009, the blazar 3C 454.3 became the brightest high energy source in the sky. Its photon flux reached and surpassed the level of 1e-5 ph/cm2/s above 100 MeV. The Swift satellite observed the source several times during the period of high gamma-ray flux, and we can construct really simultaneous spectral energy distributions (SED) before, during, and after the luminosity peak. Our main findings are: i) the optical, X-ray and gamma-ray fluxes correlate; ii) the gamma-ray flux varies quadratically (or even more) with the optical flux; iii) a simple one-zone synchrotron inverse Compton model can account for all the considered SED; iv) in this framework the gamma-ray vs optical flux correlation can be explained if the magnetic field is slightly fainter when the overall jet luminosity is stronger; v) the power that the jet spent to produce the peak gamma-ray luminosity is of the same order, or larger, than the accretion disk luminosity. During the flare, the total jet power surely surpassed the accretion power.

description: We report the detection of two very eccentric planets orbiting HD4113 and HD156846 with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss telescope at La Silla. The first planet, HD4113b, has minimum mass of $m\sin{i}=1.6\pm0.2 M_{\rm Jup}$, a period of $P=526.59\pm0.21$ days and an eccentricity of $e=0.903\pm0.02$. It orbits a metal rich G5V star at $a=1.28$ AU which displays an additional radial velocity drift of 28 m s$^{-1}$/yr observed during 8 years. The combination of the radial-velocity data and the non-detection of any main sequence stellar companion in our high contrast images taken at the VLT with NACO/SDI, characterizes the companion as a probable brown dwarf or as a faint white dwarf. The second planet, \object{HD 156846 b}, has minimum mass of $m\sin{i}=10.45\pm0.05$ M$_{\rm Jup}$, a period of $P=359.51\pm0.09 $ days, an eccentricity of $e=0.847\pm0.002$ and is located at $a=1.0$ AU from its parent star. HD156846 is a metal rich G0 dwarf and is also the primary of a wide binary system ($a>250$ AU, $P>4000$ years). Its stellar companion, \object{IDS 17147-1914 B}, is a M4 dwarf. The very high eccentricities of both planets can be explained by Kozai oscillations induced by the presence of a third object.

description: We give an example of a geometry in which two metallic objects in vacuum experience a repulsive Casimir force. The geometry consists of an elongated metal particle centered above a metal plate with a hole. We prove that this geometry has a repulsive regime using a symmetry argument and confirm it with numerical calculations for both perfect and realistic metals. The system does not support stable levitation, as the particle is unstable to displacements away from the symmetry axis.

description: : Network Text Analysis (NTA) involves the creation of networks of words and/or concepts from linguistic data. Its key insight is that the position of words and concepts in a text network provides vital clues to the central and underlying themes of the text as a whole. Recent research has relied on inductive approaches to identify these themes. In this study we demonstrate a deductive approach that we apply to the screenplay of American Sniper, an Academy Award nominee for Best Adapted Screenplay in 2014. Specifically, we first use genre expectations theory to establish prior expectations as to the key themes associated with war films. We then empirically test whether words and concepts associated with the most influentially-positioned nodes are consistent with themes common to the war-film genre. As predicted, we find that words and concepts associated with the least constrained nodes in the text network were significantly more likely to be associated with the war, action, and biography genres and significantly less likely to be associated with the mystery, science-fiction, fantasy, and film-noir genres.
