description: Improving the sustainability of built assets in the light of uncertain futures is a major challenge facing the Facilities Management profession. A changing climate poses significant challenges to the performance of built assets in-use and could potentially render many built assets prematurely obsolete. How business clients plan for such changes formed the focus of a research project undertaken by the authors. This paper presents the findings of a 12 month Action Research project that sought to identify the impact of future climate change on the performance of a new £75m education building over the first 60 years of operation. The Action Research project involved a series of meetings and workshops between the building’s design team (Architects, Engineers and Cost Consultants) and the Client’s Facilities Management (FM) Department where the impact that a range of future weather scenarios could have on the buildings performance in-use were evaluated. Technical and operational adaptation solutions were developed for those scenarios that were deemed ‘high impact’ and selected interventions were integrated into the building life cycle as pro-active adaptation steps in the built asset management plan. This paper will describe the adaptation framework used to inform the development of the various scenarios/adaptation solutions and discuss the role of the FM in the process. The paper concludes that the presence of the FM Department in the design team was critical to the development of viable climate change adaptation solutions.

description: Using first-principles calculations within density functional theory we demonstrate that the adsorption of single oxygen atom results in significant electron transfer from graphene to oxygen. This strongly disturbs the charge landscape of the C-C bonds at the proximity. Additional oxygen atoms adsorbing to graphene prefer always the C-C bonds having highest charge density and consequently they have tendency to form domain structure. While oxygen adsorption to one side of graphene ends with significant buckling, the adsorption to both sides with similar domain pattern is favored. The binding energy displays an oscillatory variation and the band gap widens with increasing oxygen coverage. While a single oxygen atom migrates over the C-C bonds on graphene surface, a repulsive interaction prevents two oxygen adatoms from forming an oxygen molecule. Our first-principles study together with finite temperature ab-initio molecular dynamics calculations concludes that oxygen adatoms on graphene cannot desorb easily without influence of external agents.

title: The role of learning institutions in Ptolemaic Alexandria
Creators: name: Cunningham, Jeffrey Jay
Publisher: name: Western Washington University
Year: 2010

description:
Hellenistic monarchs were fervently competitive with one another in the pursuit of political and cultural dominance in the Eastern Mediterranean. These rulers used their power, influence, and patronage to promote themselves as worthy successors of Alexander by building massive monuments and glorious capital cities; this is how they legitimized their rule. The ruler's attempt to outshine their opponents became a key feature of Hellenistic urbanism, typified in the city of Alexandria. One of the key reasons why Alexandria was able to become the dominant city in the Hellenistic World was the existence of learning institutions such as the Great Library, Mouseion, and Serapeum, all fostered by the Ptolemaic Dynasty. Rival libraries, sponsored by foreign royal patrons, challenged the Great Libraries' supremacy in the scholastic realm. These libraries were paradigms of Hellenism in many ways. This thesis will explore the role of these learning institutions within the city of Alexandria itself, as well as their wider implications in Hellenistic society.

description: The paper gives a symplectic-geometric account of semiclassical Gaussian wave packet dynamics. We employ geometric techniques to "strip away" the symplectic structure behind the time-dependent Schrödinger equation and incorporate it into semiclassical wave packet dynamics. We show that the Gaussian wave packet dynamics is a Hamiltonian system with respect to the symplectic structure, apply the theory of symplectic reduction and reconstruction to the dynamics, and discuss dynamic and geometric phases in semiclassical mechanics. A simple harmonic oscillator example is worked out to illustrate the results: We show that the reduced semiclassical harmonic oscillator dynamics is completely integrable by finding the action--angle coordinates for the system, and calculate the associated dynamic and geometric phases explicitly. We also propose an asymptotic approximation of the potential term that provides a practical semiclassical correction term to the approximation by Heller. Numerical results for a simple one-dimensional example show that the semiclassical correction term realizes a semiclassical tunneling.

description: Struggles of Working Women in the Administrative Sector (New Delhi) Research project by Lakshita Ankem This project delves into the multifaceted struggles encountered by women working in the administrative sector in New Delhi, shedding light on the unique challenges that they confront in their professional endeavors. Against the backdrop of the bustling administrative landscape of the nation's capital, this research aims to identify and analyze the barriers impeding the career progression and well-being of working women. Employing a comprehensive research methodology that includes surveys, case studies, and notably, in-depth interviews, this study actively engages with the lived experiences of over 270 working women in New Delhi's administrative sector. The interviews serve as a critical tool for understanding the nuanced perspectives, aspirations, and challenges faced by these women, providing rich qualitative data to complement quantitative analyses. The research investigates issues such as gender bias, unequal opportunities, workplace harassment, and the intersectionality of challenges faced by women from diverse socio-economic backgrounds. By synthesizing the findings from both quantitative and qualitative approaches, the study aims to offer a holistic understanding of the struggles and triumphs of women navigating the administrative sector. This project not only contributes valuable insights to the academic discourse surrounding gender dynamics in the workplace but also strives to provide practical recommendations for fostering a more inclusive and supportive environment. Through amplifying the voices of these working women, the research advocates for positive change, promoting gender equality and empowering women to thrive in their administrative careers in New Delhi.

description: We discuss the coexistence of antiferromagnetism and d-wave superconductivity within the so-called statistically-consistent Gutzwiller approximation (SGA) applied to the t-J-U model. In this approach, the averages calculated in a self-consistent manner coincide with those determined variationally. Such consistency is not guaranteed within the standard renormalized mean field theory. With the help of SGA, we show that for the typical value J/|t| = 1/3, coexistence of antiferromagnetism (AF) and superconductivity (SC) appears only for U/|t| > 10.6 and in a very narrow range of doping (δ< 0.006) in the vicinity of the Mott insulating state, in contrast to some previous reports. In the coexistent AF+SC phase, a staggered spin-triplet component of the superconducting gap appears also naturally; its value is very small.

description: Data-based approaches are promising alternatives to the traditional analytical constitutive models for solid mechanics. Herein, we propose a Gaussian process (GP) based constitutive modeling framework, specifically focusing on planar, hyperelastic and incompressible soft tissues. The strain energy density of soft tissues is modeled as a GP, which can be regressed to experimental stress-strain data obtained from biaxial experiments. Moreover, the GP model can be weakly constrained to be convex. A key advantage of a GP-based model is that, in addition to the mean value, it provides a probability density (i.e. associated uncertainty) for the strain energy density. To simulate the effect of this uncertainty, a non-intrusive stochastic finite element analysis (SFEA) framework is proposed. The proposed framework is verified against an artificial dataset based on the Gasser--Ogden--Holzapfel model and applied to a real experimental dataset of a porcine aortic valve leaflet tissue. Results show that the proposed framework can be trained with limited experimental data and fits the data better than several existing models. The SFEA framework provides a straightforward way of using the experimental data and quantifying the resulting uncertainty in simulation-based predictions.

description: The main objective of the Wide Field Monitor (WFM) on the LOFT mission is to provide unambiguous detection of the high-energy sources in a large field of view, in order to support science operations of the LOFT primary instrument, the LAD. The monitor will also provide by itself a large number of results on the timing and spectral behaviour of hundreds of galactic compact objects, Active Galactic Nuclei and Gamma-Ray Bursts. The WFM is based on the coded aperture concept where a position sensitive detector records the shadow of a mask projected by the celestial sources. The proposed WFM detector plane, based on Double Sided micro-Strip Silicon Detectors (DSSD), will allow proper 2-dimensional recording of the projected shadows. Indeed the positioning of the photon interaction in the detector with equivalent fine resolution in both directions insures the best imaging capability compatible with the allocated budgets for this telescope on LOFT. We will describe here the overall configuration of this 2D-WFM and the design and characteristics of the DSSD detector plane including its imaging and spectral performances. We will also present a number of simulated results discussing the advantages that this configuration offers to LOFT. A DSSD-based WFM will in particular reduce significantly the source confusion experienced by the WFM in crowded regions of the sky like the Galactic Center and will in general increase the observatory science capability of the mission.

description: We investigate the parameterization of deep neural networks that by design satisfy the continuity equation, a fundamental conservation law. This is enabled by the observation that any solution of the continuity equation can be represented as a divergence-free vector field. We hence propose building divergence-free neural networks through the concept of differential forms, and with the aid of automatic differentiation, realize two practical constructions. As a result, we can parameterize pairs of densities and vector fields that always exactly satisfy the continuity equation, foregoing the need for extra penalty methods or expensive numerical simulation. Furthermore, we prove these models are universal and so can be used to represent any divergence-free vector field. Finally, we experimentally validate our approaches by computing neural network-based solutions to fluid equations, solving for the Hodge decomposition, and learning dynamical optimal transport maps.

subject: Wildland-Urban Interface

description: Structure hardening is a key strategy to help mitigate building destruction during wildland-urban interface (WUI) fires. While hardening all exterior components of a structure is important, windows have specifically been identified as a vulnerable part of a building. The purpose of this study is to characterize the heat transfer through single- and double-pane windows constructed of plain and tempered glass. Double-pane windows with and without low-emissivity coatings and with either air or argon-filled gaps are included in this study. Small-scale experiments were performed on 23 cm x 23~cm windows exposed to a radiant panel producing centerpoint heat fluxes of 10, 20, 30, 40, and 50 kW/m2 to the exposed side of the glass. Each experimental condition was tested in triplicate. Total and radiative heat flux was measured 5.1 cm behind the unexposed side of the glass at the center of the window. Additionally, total heat flux was measured in the bottom corner of the window to characterize the difference in uniformity of heat transfer across the plane of the window. Surface temperatures on the exposed and unexposed side of the glass were measured in various locations using type K inconel-sheathed thermocouples. Tests lasted for either 20 minutes, until glass failure, or until frame failure. Times to glass crack and failure were recorded. Results showed that double-pane windows reduce heat transfer through a window compared to single-pane windows (13-43% and 39-60% of incident measured, respectively); additionally, the application of a low-emissivity coating is effective (heat fluxes measured were 5-17% of incident). Plain vs. tempered glass and air vs. argon-filled pane gaps do not yield statistically different results in heat flux measured behind the window. Temperatures were not uniform across the plane of the glass on both the exposed and unexposed sides. Finally, tempered glass had better survivability than plain glass (22/23 and 0/16 survived at incident heat fluxes up to 30 kW/m2, respectively), and double-pane argon-filled windows consistently survived longer than double-pane air-filled windows.
Structure of A High-Speed Rail Corridor: Long-term planning implications for sustainable regional development along HSR Corridor
Creators: name: Shreyas Bharule
Publisher: name: F1000 Research Limited
Year: 2023

description: Along the High-Speed Rail (HSR) corridors in Asia and Europe, trade migration has intensified economic networks between cities and created an urban-regional development ecosystem where cities along the HSR corridor form a mega-region and reinforce each other. However, throughout the literature, the introduction of HSR has mainly been associated with the urban service sector. Therefore, it has become necessary to identify the implications for regional land development strategies. This paper summarizes the key areas impacted by HSR infrastructure investments that aid in creating a region of impact. The work focuses on creating a theoretical framework for the structure of the HSR corridor. The framework is based on a literature review and a case study of established HSR projects worldwide.

description: The Immersed Boundary (IB) method is a widely-used numerical methodology for the simulation of fluid-structure interaction problems. The IB method utilizes an Eulerian discretization for the fluid equations of motion while maintaining a Lagrangian representation of structural objects. Operators are defined for transmitting information (forces and velocities) between these two representations. Most IB simulations represent their structures with piecewise-linear approximations and utilize Hookean spring models to approximate structural forces. Our specific motivation is the modeling of platelets in hemodynamic flows. In this paper, we study two alternative representations - radial basis functions (RBFs) and Fourier-based (trigonometric polynomials and spherical harmonics) representations - for the modeling of platelets in two and three dimensions within the IB framework, and compare our results with the traditional piecewise-linear approximation methodology. For different representative shapes, we examine the geometric modeling errors (position and normal vectors), force computation errors, and computational cost and provide an engineering trade-off strategy for when and why one might select to employ these different representations.

description: Two-dimensional (2D) materials assembled into van der Waals (vdW) heterostructures contain unlimited combinations of mechanical, optical, and electrical properties that can be harnessed for potential device applications. Critically, these structures require control over interfacial adhesion in order for them to be constructed and to have enough integrity to survive industrial fabrication processes upon their integration. Here, we promptly determine the quality of adhesion of various exfoliated 2D materials on conventional SiO$_{2}$/Si substrates using ultrasonic delamination threshold testing. This test allows us to quickly infer relative substrate adhesion based on the percent area of 2D flakes that survive a fixed time in an ultrasonic bath, allowing for control over process parameters that yield high or poor adhesion. We leverage this control of adhesion to optimize the vdW heterostructure assembly process, where we show that samples with high or low substrate adhesion relative to each other can be used selectively to construct high-throughput vdW stacks. Instead of tuning the adhesion of polymer stamps to 2D materials with constant 2D-substrate adhesion, we tune the 2D-substrate adhesion with constant stamp adhesion to 2D materials. The polymer stamps may be reused without any polymer melting steps, thus avoiding high temperatures (<120°C) and allowing for high-throughput production. We show that this procedure can be used to create high-quality 2D twisted bilayer graphene on SiO$_{2}$/Si, characterized with atomic force microscopy and Raman spectroscopic mapping, as well as low-angle twisted bilayer WSe$_{2}$ on h-BN/SiO$_{2}$/Si, where we show direct real-space visualization of moiré reconstruction with tilt angle-dependent scanning electron microscopy.

As a consequence, the existing upper bounds on the coefficients of the tensor $(K_{F}) $ can be used improve the bounds on the magnitude of the nonminimal coupling, $λ(K_{F}),$ by the factors $10^{5}$ or $10^{25}.$ The nonminimal coupling also generates higher-order derivative contributions to the gauge field effective action quadratic terms.

description: Vela X-1 is the archetype of high-mass X-ray binaries, composed of a neutron star and a massive B supergiant. The supergiant is a source of a strong radiatively-driven stellar wind. The neutron star sweeps up this wind, and creates a huge amount of X-rays as a result of energy release during the process of wind accretion. Here we provide detailed NLTE models of the Vela X-1 envelope. We study how the X-rays photoionize the wind and destroy the ions responsible for the wind acceleration. The resulting decrease of the radiative force explains the observed reduction of the wind terminal velocity in a direction to the neutron star. The X-rays create a distinct photoionized region around the neutron star filled with a stagnating flow. The existence of such photoionized bubbles is a general property of high-mass X-ray binaries. We unveiled a new principle governing these complex objects, according to which there is an upper limit to the X-ray luminosity the compact star can have without suspending the wind due to inefficient line driving

description: Using sentiment analysis, k-means clustering, and latent Dirichlet allocation (LDA), we collected and analyzed more than 50,000 user-generated content (UGC) related to five athletic apparel brands, to examine the content characteristics in brand-related UGC from three types of social media: Twitter (self-media), Reddit (collaboration platform), and Instagram and YouTube (creative outlets). We find that UGC on creative outlets contains more positive brand sentiments and emotional trigger words. UGC on self-media and collaboration platforms are brand-centered, while the most popular topics on self-media are brand news/trends, and it is a product-related question on collaboration platforms. UGC on creative outlets are self-promoting, while creators’ motivations and achievements are the most popular on Instagram, and activity-related content and informative reviews are the most popular on YouTube. Besides, the formation of brand communities positively influences consumer engagement on social media. This research extended from the previous framework for comparing brand-related UGC with big data and machine learning techniques. It provides insights into how channel characteristics result in differences in brand-related UGC, which are valuable to future researchers and brand managers.

We transform the Cauchy problem to a mixed problem posed on a fundamental domain determined by the quaternionic calculus. We adopt a variational approach using a space of finite elements that is invariant under the action of the binary icosahedral group. The computation of the transient waves is validated with their spectral analysis by computing a lot of eigenvalues of the Laplace-Beltrami operator.

description: Layered α-RuCl3 is a promising material to potentially realize the long-sought Kitaev quantum spin liquid with fractionalized excitations. While evidence of this exotic state has been reported under a modest in-plane magnetic field, such behavior is largely inconsistent with theoretical expectations of Kitaev phases emerging only in out-of-plane fields. These predicted field-induced states have been mostly out of reach due to the strong easy-plane anisotropy of bulk crystals, however. We use a combination of tunneling spectroscopy, magnetotransport, electron diffraction, and ab initio calculations to study the layer-dependent magnons, anisotropy, structure, and exchange coupling in atomically thin samples. Due to structural distortions, the sign of the average off-diagonal exchange changes in monolayer α-RuCl3, leading to a reversal of magnetic anisotropy to easy-axis. Our work provides a new avenue to tune the magnetic interactions in α-RuCl3 and allows theoretically predicted quantum spin liquid phases for out-of-plane fields to be more experimentally accessible.

description: Unsupervised anomaly detection models which are trained solely by healthy data, have gained importance in the recent years, as the annotation of medical data is a tedious task. Autoencoders and generative adversarial networks are the standard anomaly detection methods that are utilized to learn the data distribution. However, they fall short when it comes to inference and evaluation of the likelihood of test samples. We propose a novel combination of generative models and a probabilistic graphical model. After encoding image samples by autoencoders, the distribution of data is modeled by Random and Tensorized Sum-Product Networks ensuring exact and efficient inference at test time. We evaluate different autoencoder architectures in combination with Random and Tensorized Sum-Product Networks on mammography images using patch-wise processing and observe superior performance over utilizing the models standalone and state-of-the-art in anomaly detection for medical data.

title: Shelter competition between native signal crayfish and non-native red swamp crayfish in Pine Lake, Sammamish, Washington: the role of size and sex
Creators: name: Mueller, Karl W.
Publisher: name: Western Washington University

description:
Freshwater crayfish (Decapoda) communities worldwide are becoming increasingly similar from location to location by the intentional or accidental introduction of North American crayfishes. The red swamp crayfish (Procambarus clarkii, Cambaridae), which is native to the south-central United States and northeastern Mexico, is the most widely introduced crayfish in the world. It was first discovered in Pine Lake, Sammamish, Washington in 2000. The results of a 2005 baseline survey of the crayfish in Pine Lake suggested that the red swamp crayfish was displacing the native signal crayfish (Pacifastacus leniusculus, Astacidae). One mechanism through which non-native crayfishes displace native species is competitive interaction over shelter that influences susceptibility to predation. Field experiments were designed to explore how crayfish size and sex influence shelter occupancy in mixed-species pairs of signal crayfish and red swamp crayfish competing for limited shelter inside enclosures placed on the bottom of Pine Lake. In addition, the relative survivorship of signal crayfish and red swamp crayfish was quantified in experiments where mixed-species pairs were tethered outside of single shelters. Irrespective of species and sex, when paired with smaller heterospecifics, large crayfish readily monopolized the shelters inside the enclosures. When contestants were size-matched, the dominant crayfish or 'winner' was typically the one with longer chelae; frequently, this was the signal crayfish. Female crayfishes also were adept at monopolizing the shelter. The tether experiments revealed no significant differences in survivorship between species. These results suggest that additional mechanisms besides shelter competition are contributing to the possible displacement of signal crayfish at Pine Lake.

An Assessment of Aerogravity-Assisted Trajectories for Aerocapture at the Ice Giants

description: The Ice Giants, Neptune and Uranus, are two candidates for an aerocapture maneuver, in which a spacecraft is captured into a bound orbit through a single atmospheric pass. Another aeroassisted maneuver, the aerogravity-assist (AGA), uses an atmospheric pass to increase the turn angle about a planet, thus enabling large changes in a spacecraft's heliocentric velocity. Both maneuvers require high arrival velocities and thermal protection system technologies; thus, it may be beneficial to execute both maneuvers on a single mission. To investigate the possible benefit of an AGA trajectory for setting up an aerocapture maneuver at the Ice Giants, a two-layer optimization approach has been employed to investigate the trajectory space. As an AGA maneuver relies on minimal planetocentric velocity loss due to drag, previous studies have focused on AGAs with high lift-to-drag ratio (L/D) vehicles, despite all heritage interplanetary vehicles being low-L/D. Due to the technology barrier for high-L/D interplanetary vehicles, the present study uses lower L/D vehicles, from low-L/D heritage vehicles to mid-L/D optimally-shaped vehicles. Feasible trajectories are identified for both Uranus and Neptune that increase the number of feasible launches as compared to traditional gravity-assisted (GA) trajectories. In addition, the study identifies a new family of periodic high-altitude AGA trajectories to Uranus that are feasible using heritage vehicles. For Uranus, trajectories are identified that enable aerocapture within current heat shield technology constraints using a vehicle with L/D = 1.25.
Site-selective ion beam synthesis and optical properties of individual CdSe nanocrystal quantum dots in a SiO2 matrix

description: Cadmium selenide nanocrystal quantum dots (NC-QDs) are site-selectively synthesized by sequential ion beam implantation of selenium and cadmium ions in a SiO2 matrix through sub-micron apertures followed by a rapid thermal annealing step. The size, areal density and optical emission energy of the NC-QDs are controlled by the ion fluence during implantation and the diameter of implantation aperture. For low fluences and small apertures the emission of these optically active emitters is blue-shifted compared to that of the bulk material by $>100\,{\rm meV}$ due to quantum confinement. The emission exhibits spectral diffusion and blinking on a second timescales as established also for solution synthesized NC-QDs.

description: Detroit, Michigan, and its residents have suffered through economic, social, and environmental hardships from the fall of industrialization since 1950. Some of the largest issues within the city of Detroit are high vacancy rates, high unemployment rates, poverty, and overall lack of acknowledgement to its residents. However, in recent years, organizations within the city have begun to implement various outreach programs to beautify Detroit, improve its current housing situation, and promote community engagement. This thesis proposition looks to help aid these efforts through the introduction of a vertical smart growth architectural hybrid typology used as a catalyst human-centric, resilient urban housing. This is accomplished through the introduction of a community-focused and supportive building program. Overall, creating a self-sufficient, live-work micro-ecosystem to bring life back into the city center.

description: We study location-scale mixture priors for nonparametric statistical problems, including multivariate regression, density estimation and classification. We show that a rate-adaptive procedure can be obtained if the prior is properly constructed. In particular, we show that adaptation is achieved if a kernel mixture prior on a regression function is constructed using a Gaussian kernel, an inverse gamma bandwidth, and Gaussian mixing weights.
