description: Consider a branching random walk evolving in a macroscopic time-inhomogeneous environment, that scales with the length $n$ of the process under study. We compute the first two terms of the asymptotic of the maximal displacement at time $n$. The coefficient of the first (ballistic) order is obtained as the solution of an optimization problem, while the second term, of order $n^{1/3}$, comes from time-inhomogeneous random walk estimates, that may be of independent interest. This result partially answers a conjecture of Fang and Zeitouni. Same techniques are used to obtain the asymptotic of other quantities, such as the consistent maximal displacement.

description: The present study examines the impact of energy intensity on the relationship between logistic performance and environmental pollution in 45 countries supporting the One Belt One Road (OBOR) project proposed to revitalize the historical Silk Road for the period between 2007 and 2018 by means of Panel Smooth Transition Regression (PSTR) analysis using the energy intensity as the threshold. The analysis results indicated that the relationship between logistics performance and environmental pollution is not linear, and energy intensity level has an important role in this relationship. The energy intensity threshold level was estimated as 3.228% and 4.432% in low and high energy intensity countries, respectively. When the energy intensity level is below the threshold in both low and high energy intensity countries, increase in logistics performance reduces environmental pollution. However, when it is above the threshold, a rise in logistics performance increases environmental pollution. In this context, reducing energy intensity is deemed helpful for the establishment of a favorable environment for logistic performance and environmental factors in the long term, leading to the reduction of environmental pollution.

description: Understanding stellar composition is fundamental not only to our comprehension of the galaxy, especially chemical evolution, but it can also shed light on the interior structure and mineralogy of exoplanets, which are formed from the same material as their host stars. Unfortunately, the underlying mathematics describing stellar mass fractions and stellar elemental abundances is difficult to parse, fragmented across the literature, and contains vexing omissions that makes any calculation far from trivial, especially for non-experts. In this treatise, we present clear mathematical formalism and clarification of inherent assumptions and normalizations within stellar composition measurements, which facilitates the conversion from stellar mass fractions to elemental abundances to molar ratios, including error propagation. We also provide an example case study of HIP 544 to further illustrate the provided equations. Given the important chemical association between stars, as well as the interdisciplinary relationship between stars and their planets, it is vital that stellar mass fractions and abundance data be more transparent and accessible to people within different sub-fields and scientific disciplines.

description: Identification of integrated models is still hindered by submodels’ uncertainty propagation. In this article, a novel identifiability and identification framework is applied to screen and establish reasonable hypotheses of an integrated instream (WASP) and catchment water quality (VENSIM) model. Using the framework, the models were linked, and critical parameters and processes identified. First, an ensemble of catchment nutrient loads was simulated with randomized parameter settings of the catchment processes (e.g. nutrient decay rates). A second Monte Carlo analysis was then staged with randomized loadings and parameter values mimicking insteam processes (e.g. algae growth). The most significant parameters and their processes were identified. This coupling of models for a two-step global sensitivity analysis is a novel approach to integrated catchment-scale water quality model identification. Catchment processes were, overall, more significant to the river’s water quality than the instream processes of this Prairie river system investigated (Qu’Appelle River).

description: The Hawaii Survey Field SSA22 is the fourth deepest Chandra X-ray field. To allow for the fullest exploration of this field, we present new optical spectroscopy from Keck/DEIMOS and Keck/LRIS, which, in combination with the literature, brings the spectroscopic completeness of the 2--8 keV sample to 62%. We also make optical spectral classifications and estimate photometric redshifts for the sources without spectroscopic redshifts. We then determine hard X-ray luminosity functions (XLFs) for the full sample of Active Galactic Nuclei (AGNs), as well as for the broad-line AGNs (BLAGNs) and the non-BLAGNs separately. Our XLF for the full sample is in good agreement with the literature, showing relatively strong evolution over the redshift range $0.25\le z < 4$. The XLFs for the BLAGNs and the non-BLAGNs imply distinct evolution with redshift, with BLAGNs becoming increasingly dominant at higher redshifts and X-ray luminosities.

description: Scholarly and policy interest on endogenous cultural institutions (ECIs) in sub-Saharan Africa (SSA) is gaining traction, albeit with a lack of robust empirical evidence on compliance determinants. This article contributes in this regard, by drawing from a sample of 200 forest-dependent households in the Santchou Landscape of Cameroon, complemented by key informant interviews (N = 17) and focus group discussions (N = 11). Using the ordinary least square and the logit model, we (i) analyze forest use practices shaped by ECIs, (ii) assess forest-based ECIs compliance determinants, and (iii) estimate the effect of compliance determinants on forest-based ECIs. We find that while norms and customs shape the harvesting of wood-based and vegetal based NTFPs, they are less likely to shape the exploitation of seed based NTFPs. Second, demographic and economic factors override socio-political determinants of ECIs. Third, elites are less likely to affect forest-based ECI compliance. Policy should leverage culturally sensitive ECIs in regulating forest resource use.

description: We present star formation rates based on cold and ionized gas measurements of Mrk 266 (NGC 5256), a system composed of two colliding gas-rich galaxies, each hosting an active galactic nucleus. Using $^{12}$CO (1-0) observations with the Combined Array for Research in Millimeter-Wave Astronomy (CARMA), we find a total H$_2$ mass in the central region of $1.1\pm0.3\times10^{10}$ $M_\odot$ which leads to a possible future star formation rate of $25\pm10 M_\odot$ yr$^{-1}$. With the Fourier Transform Spectrograph (SITELLE) on the Canada-France-Hawaii Telescope, we measure an integrated H$α$ luminosity and estimate a present-day star formation rate of $15\pm2 M_\odot$ yr$^{-1}$ in the core of the system (avoiding the two active nuclei). These results confirm that Mrk 266 is an intermediate stage merger with a relatively high recent star formation rate and enough molecular gas to sustain it for a few hundred million years. Inflowing gas associated with the merger may have triggered both the starburst episode and two AGN but the two galaxy components differ: the region around the SW nucleus appears to be more active than the NE nucleus, which seems relatively quiet. We speculate that this difference may originate in the properties of the interstellar medium in the two systems.

description: The class $\mathbf{No}$ of surreal numbers, which John Conway discovered while studying combinatorial games, possesses a rich numerical structure and shares many arithmetic and algebraic properties with the real numbers. Some work has also been done to develop analysis on $\mathbf{No}$. In this paper, we extend this work with a treatment of functions, limits, derivatives, power series, and integrals. We propose surreal definitions of the arctangent and logarithm functions using truncations of Maclaurin series. Using a new representation of surreals, we present a formula for the limit of a sequence, and we use this formula to provide a complete characterization of convergent sequences and to evaluate certain series and infinite Riemann sums via extrapolation. A similar formula allows us to evaluates limits (and hence derivatives) of functions. By defining a new topology on $\mathbf{No}$, we obtain the Intermediate Value Theorem even though $\mathbf{No}$ is not Cauchy complete, and we prove that the Fundamental Theorem of Calculus would hold for surreals if a consistent definition of integration exists. Extending our study to defining other analytic functions, evaluating power series in generality, finding a consistent definition of integration, proving Stokes' Theorem to generalize surreal integration, and studying differential equations remains open.

description: Magnetic particles exhibit nonlinear rotational drift in rotating magnetic fields, which is dependent on the particle properties and external fields. The rotational drift frequency difference from the particles on an FFL in a gradient rotational excitation field may generate a free-induction decay signal and can be used as a phase encoding method for simultaneous high-resolution and large field-of-view MPI. We propose the use of gradient-based rotational drift to excite magnetic nanoparticles on an FFL. The different rotational drift frequencies from different FFL locations induce free induction decay and refocused echo signals. Magnetic particle concentrations on the FFL can be solved by using Fourier-transform-based reconstruction. The simulation was performed using in-house developed software based on the Interactive Data Language. IDL. The 2D Shepp-Logan phantom and the digital vessel phantom were used for an FFL-based raster scan and image reconstruction simulation. The correlation coefficient between the original and reconstructed images was used for image quality assessment. The dephasing signals and echos form a k-space for image reconstruction. Reconstructed images exhibited an increasing resolution from left to right with an increasing rotational drift frequency slope under a spatially linear excitation field. In the reconstructed brain TOF-MRA image with multi-angle gradient-based rotational excitation from filtered back-projection, the main branches and small vessels are visible with a high peak SNR. In conclusion, we propose the use of gradient-based rotational drift to excite magnetic nanoparticles for high-resolution MPI.

description: Through the Master of Fine Arts program at Emily Carr University of Art + Design my work has focused on the mediated moving body as my research investigates the concept of embodiment for joy, self-awareness, and self-reflexivity. Art is an ideal vehicle to explore different ways of knowing, beyond cognition, by encouraging feeling through aesthetic affect. I came into the MFA program with professional experience in film and videography and a background in the performing arts, which influences how I approach an audience of viewers and listeners. A significant development to my practice has been the use of sound as material, working with its illusory potential, and depicting the presence of the moving body through experimental processes and makeshift sound installations. My thesis research is driven by a desire to understand, through experience; sensory perception, embodiment, the palpability of human presence through sound, and how to apprehend features of the world by listening and generating a felt sense of the physical body in space.

description: Quantum key distribution promises unconditionally secure communications. However, as practical devices tend to deviate from their specifications, the security of some practical systems is no longer valid. In particular, an adversary can exploit imperfect detectors to learn a large part of the secret key, even though the security proof claims otherwise. Recently, a practical approach---measurement-device-independent quantum key distribution---has been proposed to solve this problem. However, so far its security has only been fully proven under the assumption that the legitimate users of the system have unlimited resources. Here we fill this gap and provide a rigorous security proof against general attacks in the finite-key regime. This is obtained by applying large deviation theory, specifically the Chernoff bound, to perform parameter estimation. For the first time we demonstrate the feasibility of long-distance implementations of measurement-device-independent quantum key distribution within a reasonable time-frame of signal transmission.

description: Current bioassays for detection of antibodies or antigens such as ELISA (Enzyme-linked Immunosorbent Assay) are relatively inflexible, expensive and time-consuming. Upcoming methods, such as ACS (AC susceptometry) or MPS (Magnetic Particle Spectroscopy), exploit the magnetization response of functionalized MNP ensembles to assess specific information about the MNP mobility as well as conjugations of chemical or biological compounds on their surface. Both methods have shown promising results in the past but cannot reach the sensitivity of above-mentioned techniques. We used a novel method based on a modified MPS being sensitive to minimal changes in mobility of MNP ensembles. This facilitates robust and easy-to-handle measurements of minimal changes in the diameter of MNPs. As an example, we detected SARS-CoV-2 antibodies binding to the S1 antigen on the surface of functionalized MNPs. Without any purification or incubation, we could show a sensitivity of less than 50 ng/mL of SARS-CoV-2 antibodies in human blood.

description: Rare earth elements (REEs) are recognized as one of the most critical elements and considered essential for the development of sustainable energy technologies, lasers, electronics, alloys, catalysts, and other applications. In order to meet the increasing demand to ensure those essential usages, the supply of REEs is however limited from the primary sources. Recovery of REEs from secondary resources, such as discarded electrical and electronic equipment, referred to as electronic waste (e-waste) is consequently crucial. Fluorescent lamps among such wastes are of special concern due to the high quantity of REEs present in them. This article discusses a potential hydrometallurgical method for recovering REEs (yttrium and europium) from fluorescent lamp waste via nitric acid leaching. The effects of leaching factors including acid concentration and temperature were examined. To assist the leaching yields of those metals, the effect of alkaline fusion was specifically examined. The kinetics of both processes, direct- and alkaline fusion-assisted leaching were investigated based on the shrinking core model. In the case of direct leaching, the metal dissolution was controlled by surface chemical reaction with apparent activation energies of 43.9 and 48.1 kJ/mol for yttrium and europium, respectively, in the temperature range 303–333 K. Pretreatment, viz., the alkaline fusion changed the subsequent leaching mechanism to diffusion control with apparent activation energies of 7.4 and 9.5 kJ/mol for the respective metal in the same temperature range. Optimization of the alkaline fusion-assisted acid leaching process was undertaken by applying response surface methodology (RSM) based on the central composite design (CCD). Under the alkaline fusion conditions such as soda/fluorescent powder mass ratio of 0.65 g/g, temperature of 1223 K and reaction time of 7200 s followed by acid leaching (nitric acid concentration – 3.5 M, temperature-323 K, pulp density – 30 g/L and leaching duration – 1200 s), the leaching efficiencies of 92.6% and 99.5% for yttrium and europium, respectively, could be achieved.

description: The effect of full-duplex cooperative relaying in a random access multiuser network is investigated here. First, we model the self-interference incurred due to full-duplex operation, assuming multi-packet reception capabilities for both the relay and the destination node. Traffic at the source nodes is considered saturated and the cooperative relay, which does not have packets of its own, stores a source packet that it receives successfully in its queue when the transmission to the destination has failed. We obtain analytical expressions for key performance metrics at the relay, such as arrival and service rates, stability conditions, and average queue length, as functions of the transmission probabilities, the self interference coefficient, and the links' outage probabilities. Furthermore, we study the impact of the relay node and the self-interference coefficient on the per-user and aggregate throughput, and the average delay per packet. We show that perfect self-interference cancelation plays a crucial role when the SINR threshold is small, since it may result to worse performance in throughput and delay comparing with the half-duplex case. This is because perfect self-interference cancelation can cause an unstable queue at the relay under some conditions.

Dressing for Adventure on the West Florida Frontier

description: My inter-disciplinary study evaluates the Creole dressing genre in eighteenth century West Florida and demonstrates how groups used dress as a primary form of material culture to negotiate life-ways and identities under colonial conditions. I focus specifically on the historical archaeology of Mobile Parish, Yuchi Town, and the Chickasaw Nation. The British period, 1763-1783, saw the colonial population increase and the commercialisation of the plantation and exchange economies. Native Americans remained the region’s majority population and retained ownership of hunting lands critical to the deerskin trade, which made Indigenous peoples politically and commercially influential. Colonial and Indigenous communities were creolised in a broader sense than those who were Creoles by birth. Gulf Coast identities were distilled into constituent groups that made up each community. People fashioned identities to either suppress or flaunt heritage, faith, occupation, and wealth to associate with one or multiple groups to be drawn in. Creolisation also offered opportunities to become adventurers and increase personal and familial value through exchange or the acquisition of skills, property, or knowledge. This ideally involved conscious, self-aware switching between settlement, wilderness, and fête clothing to activate identities at appropriate moments to escape or bend hierarchies to one’s own use. The Creole genre provided the material means of resistance and negotiation in two related dressing strategies: The Art of Not Being Governed, to create alternative lives beyond hierarchies, and The Art of Being Governed, to capitalise on hierarchical structures. In this way, creolised newcomers of African, European, and of mixed heritage and Native Americans became adventurers, became Creoles, who became traders, planters or skilled workers, or runaways, and vice versa.
Using Vela X-1 to understand accretion and wind structure in High-Mss X-ray Binaries (HMXBs)

description: The spectral and timing behaviour of HMXBs offers a unique opportunity for the investigation of accretion onto compact objects and of wind structure in massive stars. The bright and persistent neutron star HMXB Vela X-1 is one of the key systems for such studies with both current and future instruments. It has a complex clumpy stellar wind, prominent cyclotron resonant scattering features (CRSFs) and strong flares. Understanding the variability of the systems on both short time scales of a few hundreds seconds and along its 9d orbit with current instruments enables us to make predictions for future observations with XRISM and Athena and to devise the best observational strategy for Vela X-1.
 Here, we analyse two new observations taken with NuSTAR and XMM-Newton at orbital phases ~0.5 and ~0.75 and follow the evolution of spectral parameters down to the pulse period (~300s) time-scale. The flux-dependency we observe in the spectral shape implies a change in the properties of the Comptonising plasma and the observed drop of the CRSF energy following a strong flare may indicate a change in the accretion geometry. The strong variability of absorption is due to the presence of a large-scale wind structure, such as accretion- and photoionisation wakes, combined with the variable line of sight as the neutron star moves along the orbit. In particular, we, for the first time, are able to trace the onset of the wakes with high time resolution and compare to predictions from simulations.

Through a systematic review of literature and interdisciplinary methodologies, we trace the evolution of swarm robotics, uncovering applications in search and rescue, environmental monitoring, agriculture, industrial automation, and space exploration. The decentralized, self-organizing nature of both social insects and robot swarms provides insights into efficient problem-solving in dynamic environments. The article delves into the ethical dimensions surrounding the use of swarm robotics, addressing concerns related to human-robot interaction, privacy, job displacement, and unintended consequences. As we navigate through challenges, emerging trends like biohybrid systems, edge computing, explainable AI, swarm simulation, and regulatory frameworks illuminate the future landscape of social insect-inspired swarms, showcasing their potential to reshape technology and society.
 
Im Bereich der Wissenschaft und Technologie haben sich von sozialen Insekten inspirierte Schwärme zu einer faszinierenden Schnittstelle zwischen Natur und Innovation entwickelt. Dieser Artikel untersucht das kollektive Verhalten sozialer Insekten wie Bienen und Ameisen und ihren transformativen Einfluss auf die Entwicklung von Roboterschwärmen. Durch eine systematische Literaturrecherche und interdisziplinäre Methoden verfolgen wir die Entwicklung der Schwarmrobotik und decken Anwendungen in den Bereichen Suche und Rettung, Umweltüberwachung, Landwirtschaft, industrielle Automatisierung und Weltraumforschung auf. Die dezentrale, selbstorganisierende Natur sowohl sozialer Insekten als auch Roboterschwärme bietet Einblicke in die effiziente Problemlösung in dynamischen Umgebungen. Der Artikel befasst sich mit den ethischen Dimensionen rund um den Einsatz von Schwarmrobotik und geht auf Bedenken im Zusammenhang mit der Mensch-Roboter-Interaktion, der Privatsphäre, der Verlagerung von Arbeitsplätzen und unbeabsichtigten Folgen ein. Während wir uns den Herausforderungen stellen, beleuchten aufkommende Trends wie Biohybridsysteme, Edge Computing, erklärbare KI, Schwarmsimulation und regulatorische Rahmenbedingungen die zukünftige Landschaft sozialer, von Insekten inspirierter Schwärme und zeigen ihr Potenzial, Technologie und Gesellschaft neu zu gestalten.

description: In this work we investigate how the MPI resolution changes as a function of signal harmonics. Based on a simulation study that models a lock-in measurement of the point spread function we apply our findings to actual measurement data obtained from NIST's MPI instrument. In both cases we show that the image resolution improves by a factor of more than two between the 3rd and 7th harmonic.

description: MPI has been on a trajectory towards clinical application in humans for years. As scanners and techniques mature, clinical testing is effectively prohibited by the lack of a clinically approved tracer. This changes now by the reintroduction of a Ferucarbotran-based tracer into the market, Resotran®. Although initially intended for use in MRI, we tested Resotran® for its viability in MPI. The other Ferucarbotran-based tracer fit for MRI and MPI is Resovist®, which is well known and characterized but was discontinued years ago. We present initial data on the characterization of Resotran® in comparison to Resovist®.

description: I previously showed that Kendall's work on shape geometry is in fact also the geometrical description of Barbour's relational mechanics' reduced configuration spaces (alias shape spaces). I now describe the extent to which Kendall's subsequent statistical application to e.g. the `standing stones problem' realizes further ideas along the lines of Barbour-type timeless records theories, albeit just at the classical level.

description: Synchronous binary asteroids can experience libration about their tidally-locked equilibrium, which will result in energy dissipation. This is an important topic to the Asteroid Impact and Deflection Assessment, where excitation caused by the DART kinetic impact in the Didymos binary asteroid system may be reduced through dissipation before Hera arrives to survey the effects of the impact. We develop a numeric model for energy dissipation in binary asteroids to explore how different system configurations affect the rate of energy dissipation. We find tumbling within the synchronous state eliminates a systematic trend in libration damping on short timescales (several years), but not over long times (hundreds of years) depending on the material conditions. Furthermore, damping of libration, eccentricity, and fluctuations in the semimajor axis are primarily dependent on the stiffness of the secondary, whereas the semimajor axis secular expansion rate is dictated by the stiffness of the primary, as expected. Systems experiencing stable planar libration in the secondary can see a noticeable reduction in libration amplitude after only a few years depending on the stiffness of the secondary, and thus dissipation should be considered during Hera's survey of Didymos. For a very dissipative secondary undergoing stable libration, Hera may be able to calculate the rate of libration damping in Dimorphos and therefore constrain its tidal parameters.
Painleve-Gullstrand coordinates versus Kerr spacetime geometry

description: We discuss the tension between the possible existence of Painleve-Gullstrand coordinate systems versus the explicit geometrical features of the Kerr spacetime; a subject of interest to Professor Thanu Padmanabhan in the weeks immediately preceding his unexpected death. We shall carefully distinguish strong and weak Painleve-Gullstrand coordinate systems, and conformal variants thereof, cataloguing what we know can and cannot be done -- sometimes we can make explicit global statements, sometimes we must resort to implicit local statements. For the Kerr spacetime the best that seems to be achievable is to set the lapse function to unity and represent the spatial slices with a 3-metric in factorized unimodular form; this arises from considering the Doran version of Kerr spacetime in Cartesian coordinates. We finish by exploring the (limited) extent to which this construction might possibly lead to implementing an "analogue spacetime" model suitable for laboratory simulations of the Kerr spacetime.

description: The confinement/deconfinement transition in gauge theory plays important roles in physics, including the description of thermal phase transitions in the dual gravitational theory. Partial deconfinement implies an intermediate phase in which color degrees of freedom split into the confined and deconfined sectors. The partially-deconfined phase is dual to the small black hole that lies between the large black hole and graviton gas. Better understandings of partial deconfinement may provide us with a clue how gravity emerges from the field theory degrees of freedom. In this article, we briefly review the basic properties of partial deconfinement and discuss applications.
