description: The movie industry has been using Unmanned Aerial Vehicles as a new tool to produce more and more complex and aesthetic camera shots. However, the shooting process currently rely on manual control of the drones which makes it difficult and sometimes inconvenient to work with. In this paper we address the lack of autonomous system to operate generic rotary-wing drones for shooting purposes. We propose a global control architecture based on a high-level generic API used by many UAV. Our solution integrates a compound and coupled model of a generic rotary-wing drone and a Full State Feedback strategy. To address the specific task of capturing cinema scenes, we combine the control architecture with an automatic camera path planning approach that encompasses cinematographic techniques. The possibilities offered by our system are demonstrated through a series of experiments.

description: The importance of security in computer and information systems is increasing as network-connected computer systems become more ubiquitous. The objective of security is to verify that the computing platform is secured and that data and information are properly accessed and handled by users and applications, ensuring data confidentiality and integrity. To develop a framework for modeling and verifying security as a data quality attribute, designers need to identify parameters and variables with the express power to capture and represent security models and determine the type of analysis to enable.

description: The halo occupation distribution (HOD) describes the relation between galaxies and dark matter at the level of individual dark matter halos. The properties of galaxies residing at the centers of halos differ from those of satellite galaxies because of differences in their formation histories. Using a smoothed particle hydrodynamics (SPH) simulation and a semianalytic (SA) galaxy formation model, we examine the separate contributions of central and satellite galaxies to the HOD, more specifically to the probability P(N|M) that a halo of virial mass M contains N galaxies of a particular class. In agreement with earlier results for dark matter subhalos, we find that the mean occupation function NM for galaxies above a baryonic mass threshold can be approximated by a step function for central galaxies plus a power law for satellites and that the distribution of satellite numbers is close to Poisson at fixed halo mass. Since the number of central galaxies is always zero or one, the width of P(N|M) is narrower than a Poisson distribution at low N and approaches Poisson at high N. For galaxy samples defined by different baryonic mass thresholds, there is a nearly linear relation between the minimum halo mass Mmin required to host a central galaxy and the mass M1 at which an average halo hosts one satellite, with M1 14Mmin (SPH) or M1 18Mmin (SA). The stellar population age of central galaxies correlates with halo mass, and this correlation explains much of the age dependence of the galaxy HOD. The mean occupation number of young galaxies exhibits a local minimum at M ~ 10Mmin where halos are too massive to host a young central galaxy but not massive enough to host satellites. Using the SA model, we show that the conditional galaxy mass function at fixed halo mass cannot be described by a Schechter function because central galaxies produce a "bump" at high masses. We suggest parameterizations for the HOD and the conditional luminosity function that can be used to model observed galaxy clustering. Many of our predictions are in good agreement with recent results inferred from clustering in the Sloan Digital Sky Survey.

description: The importance of security in computer and information systems is increasing as network-connected computer systems become more ubiquitous. The objective of security is to verify that the computing platform is secured and that data and information are properly accessed and handled by users and applications, ensuring data confidentiality and integrity. To develop a framework for modeling and verifying security as a data quality attribute, designers need to identify parameters and variables with the express power to capture and represent security models and determine the type of analysis to enable.

This post from senior architecture researcher Aaron Greenhouse presents an approach for modeling and validating confidentiality based on the Bell–LaPadula security model using the Architecture Analysis and Design Language (AADL). It also presents 11 analysis rules that must be enforced over an AADL instance model to ensure the consistency of a security model. Mapping Bell-LaPadula to AADL allows the expression of key concepts within the AADL Model so they can be analyzed automatically.

Controlling plasmonic response and cargo release via hydrophobic nanoparticle organization within polymersome membranes
Creators: name: Salzer, Regina L.
Publisher: name: No Publisher Supplied
Year: 2024

description: Polymersomes are great candidates as carrier vesicles in cargo delivery systems due to their robust membrane and ability for dual encapsulation in the hydrophobic and hydrophilic compartments. Precise control over the release mechanism for cargo delivery remains a challenge in the field; however, light-mediated cargo release is a promising stimulus for initiating release from polymersomes with high spatiotemporal resolution. Herein, it is demonstrated that hydrophobically-functionalized gold nanoparticles (AuNPs) produced via pulsed laser ablation in liquid (PLAL) can be loaded into the hydrophobic region of the polymersome bilayer membrane to photosensitize polybutadiene-b-polyethylene oxide micron polymersomes. AuNPs functionalized with four different alkanethiol ligands were successfully produced, and the effect of ligand length on AuNP organization was investigated using high-resolution transmission electron microscopy, demonstrating no significant correlation between ligand chain length and AuNP size. Polymersomes containing AuNPs functionalized with alkanethiol ligands were incorporated into polymersomes to investigate their organization within the membrane and subsequent effect on rupture threshold in response to femtosecond irradiation, where rupture threshold is defined as the energy at which 50% of vesicles undergo complete rupture. The studies contained herein demonstrated that longer ligands decreased both the average interparticle distance in vesicle membranes and the energy required for vesicle rupture, thus suggesting that the highly ordered behavior of AuNPs functionalized with longer ligands in polymersome membranes decreases membrane stability.

description: Device-independent quantum key distribution protocols allow two honest users to establish a secret key with minimal levels of trust on the provider, as security is proven without any assumption on the inner working of the devices used for the distribution. Unfortunately, the implementation of these protocols is challenging, as it requires the observation of a large Bell-inequality violation between the two distant users. Here, we introduce novel photonic protocols for device-independent quantum key distribution exploiting single-photon sources and heralding-type architectures. The heralding process is designed so that transmission losses become irrelevant for security. We then show how the use of single-photon sources for entanglement distribution in these architectures, instead of standard entangled-pair generation schemes, provides significant improvements on the attainable key rates and distances over previous proposals. Given the current progress in single-photon sources, our work opens up a promising avenue for device-independent quantum key distribution implementations.

description: Connectionist and dynamical systems approaches explain human thought, language and behavior in terms of the emergent consequences of a large number of simple noncognitive processes. We view the entities that serve as the basis for structured probabilistic approaches as abstractions that are occasionally useful but often misleading: they have no real basis in the actual processes that give rise to linguistic and cognitive abilities or to the development of these abilities. Although structured probabilistic approaches can be useful in determining what would be optimal under certain assumptions, we propose that connectionist, dynamical systems, and related approaches, which focus on explaining the mechanisms that give rise to cognition, will be essential in achieving a full understanding of cognition and development.

description: A famous and wide-open problem, going back to at least the early 1970's, concerns the classification of chromatic polynomials of graphs. Toward this classification problem, one may ask for necessary inequalities among the coefficients of a chromatic polynomial, and we contribute such inequalities when a chromatic polynomial $χ_G(n) = χ^*_0 \binom {n+d} d + χ^*_1 \binom {n+d-1} d + \dots + χ^*_d \binom n d$ is written in terms of a binomial-coefficient basis. For example, we show that $χ^*_{ j } \le χ^*_{ d-j }$, for $0 \le j \le \frac{ d }{ 2 }$. Similar results hold for flow and tension polynomials enumerating either modular or integral nowhere-zero flows/tensions of a graph. Our theorems follow from connections among chromatic, flow, tension, and order polynomials, as well as Ehrhart polynomials of lattice polytopes that admit unimodular triangulations. Our results use Ehrhart inequalities due to Athanasiadis and Stapledon and are related to recent work by Hersh--Swartz and Breuer--Dall, where inequalities similar to some of ours were derived using algebraic-combinatorial methods.

description: Visual information from a speaker's face profoundly influences auditory perception of speech. However, relatively little is known about the extent to which visual influences may depend on experience, and extent to which new sources of visual speech information can be incorporated in speech perception. In the current study, participants were trained on completely novel visual cues for phonetic categories. Participants learned to accurately identify phonetic categories based on novel visual cues. These newly-learned visual cues influenced identification responses to auditory speech stimuli, but not to the same extent as visual cues from a speaker's face. The novel methods and results of the current study raise theoretical questions about the nature of information integration in speech perception, and open up possibilities for further research on learning in multimodal perception, which may have applications in improving speech comprehension among the hearing-impaired.

description: Over the past few years, society has seen a rebirth of interest in artificial intelligence (AI) and, more specifically, machine learning  (ML) applications. As is typical in time periods of hardware performance spikes in which computer scientists can increase the throughput of their systems, researchers have been using computers to learn from patterns in data that once took an impractical amount of time to process. This capability has not been limited to large, corporate entities; the advent of graphics processing units (GPUs) has enabled even non-corporate equipment to process large data sets. On a corporate scale, machines with multiple GPUs are used in data centers to mine information and identify data patterns like never before.  How can engineers organize such systems to take advantage of all the practices proposed by Agile methodologies and the more recent DevSecOps developments? In this blog post, I will explore the machine learning (ML) and DevSecOps domains and propose ways to use them in collaboration for increased performance.

description: Using a canonical formalism, we determine the equation of state and the phase diagram of eight-flavour QCD, as a function of temperature and isospin density. Two mechanisms are at work: Bose condensation of pions at high density, and deconfinement at high temperature. We study their interplay and find that on our small and coarse lattice the first order deconfinement transition appears to end at a critical point at finite density. We investigate the strength of the overlap and of the sign problems and discuss implications for the baryonic density case.

description: Owing to both electronic and dielectric confinement effects, two-dimensional organic-inorganic hybrid perovskites sustain strongly bound excitons at room temperature. Here, we demonstrate that there are non-negligible contributions to the excitonic correlations that are specific to the lattice structure and its polar fluctuations, both of which are controlled via the chemical nature of the organic counter-cation. We present a phenomenological, yet quantitative framework to simulate excitonic absorption lineshapes in single-layer organic-inorganic hybrid perovskites, based on the two-dimensional Wannier formalism. We include four distinct excitonic states separated by $35\pm5$\,meV, and additional vibronic progressions. Intriguingly, the associated Huang-Rhys factors and the relevant phonon energies show substantial variation with temperature and the nature of the organic cation. This points to the hybrid nature of the lineshape, with a form well described by a Wannier formalism, but with signatures of strong coupling to localized vibrations, and polaronic effects perceived through excitonic correlations. Our work highlights the complexity of excitonic properties in this class of nanostructured materials.

description: Visual recognition of objects is an impressively difficult problem that biological systems solve effortlessly. We consider two aspects of this ability. First, is the recognition of all objects accomplished by either a single system or multiple, domain-specific systems? Behavioral, neuropsychological and neuroimaging data indicate that a single system is sufficient for the recognition of all objects at all levels. Second, how does such a system 'tune' itself to the constraints imposed by recognition at different levels of specificity? Evidence indicates that the task demands and learning that arise from different forms of feedback determine which computational routines are recruited automatically in object recognition.

description: The present study investigated how people learn to correct errors in actions directed toward cognitively encoded spatial locations. Subjects inserted a stylus to reach a hidden target localized by means of ultrasound imaging and portrayed with a scaled graph. As was found previously (Wu et al., 2005), subjects initially underestimated the target location but corrected their responses when given training with feedback. Three experiments were conducted to examine whether the error correction occurred at (1) the mapping from the input to a mental representation of target location; (2) the mapping from the representation of target location to the intended insertion response, or (3) the mapping from intended response to action. Experiment 1 and Experiment 3 disconfirmed Mappings 1 and 3, respectively, by showing that training did not alter independent measures of target localization or the action of aiming. Experiment 2 showed that the output of Mapping 2, the planned response -- measured as the initial insertion angle -was corrected over trials, and the correction magnitude predicted the response to a transfer stimulus with a new represented location.

description: A majority of English words are stressed on their first syllable. Infants use stress as a cue to word segmentation, but it is unclear how infants discover the correlation between stress and word boundaries. We exposed English-learning infants to a list of words stressed on their second syllable to discover whether infants can learn a new relation between stress and word boundaries. English-learning infants treat stressed syllables as word onsets, which is incorrect in words where stressed syllables occur second (iambic words). A brief exposure allowed infants to subsequently segment iambic words correctly, whether the exposure consisted of 100% or 80% iambic words. We also trained 7-month-olds—who typically rely on transitional probabilities—to use stress as a cue to word segmentation. The results suggest that infants are sensitive to the distribution of stress across word position and that altering this distribution affects their segmentation strategies.
Boosting Random Forests to Reduce Bias; One-Step Boosted Forest and its Variance Estimate

description: In this paper we propose using the principle of boosting to reduce the bias of a random forest prediction in the regression setting. From the original random forest fit we extract the residuals and then fit another random forest to these residuals. We call the sum of these two random forests a \textit{one-step boosted forest}. We show with simulated and real data that the one-step boosted forest has a reduced bias compared to the original random forest. The paper also provides a variance estimate of the one-step boosted forest by an extension of the infinitesimal Jackknife estimator. Using this variance estimate we can construct prediction intervals for the boosted forest and we show that they have good coverage probabilities. Combining the bias reduction and the variance estimate we show that the one-step boosted forest has a significant reduction in predictive mean squared error and thus an improvement in predictive performance. When applied on datasets from the UCI database, one-step boosted forest performs better than random forest and gradient boosting machine algorithms. Theoretically we can also extend such a boosting process to more than one step and the same principles outlined in this paper can be used to find variance estimates for such predictors. Such boosting will reduce bias even further but it risks over-fitting and also increases the computational burden.

description: Learning to understand a single causal system can be an achievement, but humans must learn about multiple causal systems over the course of a lifetime. We present a hierarchical Bayesian framework that helps to explain how learning about several causal systems can accelerate learning about systems that are subsequently encountered. Given experience with a set of objects, our framework learns a causal model for each object and a causal schema that captures commonalities among these causal models. The schema organizes the objects into categories and specifies the causal powers and characteristic features of these categories and the characteristic causal interactions between categories. A schema of this kind allows causal models for subsequent objects to be rapidly learned, and we explore this accelerated learning in four experiments. Our results confirm that humans learn rapidly about the causal powers of novel objects, and we show that our framework accounts better for our data than alternative models of causal learning.

description: Planets accompany most sun-like stars. The orbits of many are sufficiently close that they will be engulfed when their host stars ascend the giant branch. This Letter compares the power generated by orbital decay of an engulfed planet to the intrinsic stellar luminosity. Orbital decay power is generated by drag on the engulfed companion by the surrounding envelope. As stars ascend the giant branch their envelope density drops and so does the power injected through orbital decay, scaling approximately as $L_{\rm decay} \propto R_*^{-9/2}$. Their luminosity, however, increases along the giant branch. These opposed scalings indicate a crossing, where $L_{\rm decay}= L_*$. We consider the engulfment of planets along isochrones in the Hertzsprung-Russell (H-R) diagram. We find that the conditions for such a crossing occur around $L_*\approx 10^2$~$L_\odot$ (or $a\approx 0.1$~au) for Jovian planetary companions. The consumption of closer-in giant planets, such as hot Jupiters, leads to $L_{\rm decay}\gg L_*$, while more distant planets such as warm Jupiters, $a\approx 0.5$~au, lead to minor perturbations of their host stars with $L_{\rm decay} \ll L_*$. Our results map out the parameter space along the giant branch in the H-R Diagram where interaction with planetary companions leads to significant energetic disturbance of host stars.

description: In the framework of the classical Glauber approach, the analytical expressions for the variance of the number of wounded nucleons and binary collisions in AA interactions at a given centrality are presented. Along with the optical approximation term, they contain additional contact terms arising only in the case of nucleus-nucleus collisions. The magnitude of the additional contributions, e.g., for PbPb collisions at SPS energies, is larger than the contribution of the optical approximation at some values of the impact parameter. The sum of the additional contributions is in good agreement with the results of independent Monte Carlo simulations of this process. Due to these additional terms, the variance of the total number of participants for peripheral PbPb collisions and the variance of the number of collisions at all values of the impact parameter exceed several multiples of the Poisson variances. The correlator between the numbers of participants in colliding nuclei at fixed centrality is also analytically calculated.

Dualities in equivariant Kasparov theory

description: We study several duality isomorphisms between equivariant bivariant K-theory groups, generalising Kasparov's first and second Poincare duality isomorphisms. We use the first duality to define an equivariant generalisation of Lefschetz invariants of generalised self-maps. The second duality is related to the description of bivariant Kasparov theory for commutative C*-algebras by families of elliptic pseudodifferential operators. For many groupoids, both dualities apply to a universal proper G-space. This is a basic requirement for the dual Dirac method and allows us to describe the Baum-Connes assembly map via localisation of categories.

Subjects: Software Engineering

description: In 2023, I had the pleasure of working with a group of talented interns who joined the Software Engineering Institute (SEI) for the summer to gain insight into the research we conduct and experience in applying the concepts we study and develop. This SEI blog post, authored by the interns themselves, describes their work on an example case in which they designed and implemented a microservices-based software application along with an accompanying DevSecOps pipeline. In the process, they expanded the concept of minimum viable product to minimum viable process. I’d like to thank the following interns for their hard work and contributions: Evan Chen, University of California, San Diego Zoe Angell, Carnegie Mellon University Emily Wolfe and Sam Shadle, Franciscan University of Steubenville Meryem Marasli and Berfin Bircan, University of Pittsburgh Genavive Chick, University of Georgia

description: Sustainable software development and metadata practices are crucial for making research software FAIR. Undeniably, this requires an initial investment of time and effort for researching and adopting best practices, as well as for regular maintenance tasks. This impairs the bottom-up adoption of best practices by RSEs. In this talk we present two complementary tools addressing this challenge:

The command-line tool somesy(1) organizes and synchronizes software project metadata across multiple required or recommended files that are typically used in a software project. It is designed for easy integration into the development workflow, reducing the overhead for software metadata management.

The fair-python-cookiecutter(2) is a git repository template providing a well-structured foundation for new Python projects. The detailed documentation also turns it into a hands-on educational resource. Besides combining various state-of-the-art tools, it includes somesy to simplify software metadata management. The template follows software engineering practices recommended by DLR and OpenSSF. Furthermore, it supports relevant metadata standards such as REUSE, CITATION.cff and CodeMeta.

description: The article examines the problem of age dynamics in the elementary school of a generalized way of solving problems. Two classes of students at the end of the second, third and fourth years of study in a group experiment solve spatial combinatorial problems in a visual-figurative form. It was shown that from the second grade to the fourth, the number of students who are able to solve search problems in a general, theoretical way increases significantly, and the number of students who are able to solve such problems in a particular, empirical way decreases less significantly.
Directional Dicke Subradiance with Nonclassical and Classical Light Sources

description: We investigate Dicke subradiance of distant quantum sources in free space, i.e., the spatial emission pattern of spontaneously radiating non-interacting multi-level atoms or multi-photon sources, prepared in totally antisymmetric states. We find that the radiated intensity is marked by a strong suppression of spontaneous emission in particular directions. In resemblance to the analogous, yet inverted, superradiant emission profiles of $N$ distant two-level atoms prepared in symmetric Dicke states, we call the corresponding emission pattern $\textit{directional Dicke subradiance}$. We also show that higher order intensity correlations of the light incoherently emitted by statistically independent thermal light sources display the same directional Dicke subradiant behavior. We present measurements of directional Dicke subradiance for $N = 2, \ldots, 5$ distant thermal light sources corroborating the theoretical findings.

Star Clusters in Evolving Galaxies

description: Their ubiquity and extreme densities make star clusters probes of prime importance of galaxy evolution. Old globular clusters keep imprints of the physical conditions of their assembly in the early Universe, and younger stellar objects, observationally resolved, tell us about the mechanisms at stake in their formation. Yet, we still do not understand the diversity involved: why is star cluster formation limited to 1e5 Msun objects in the Milky Way, while some dwarf galaxies like NGC 1705 are able to produce clusters 10 times more massive? Why do dwarfs generally host a higher specific frequency of clusters than larger galaxies? How to connect the present-day, often resolved, stellar systems to the formation of globular clusters at high redshift? And how do these links depend on the galactic and cosmological environments of these clusters? In this review, I present recent advances on star cluster formation and evolution, in galactic and cosmological context. The emphasis is put on the theory, formation scenarios and the effects of the environment on the evolution of the global properties of clusters. A few open questions are identified.
