description: We compute the effects of thermal Comptonization of soft photons emitted from a Kep- lerian disk around a black hole by the post-shock region of a sub-Keplerian flow, known as the CENtrifugal pressure dominated BOundary Layer (CENBOL). We show that the spectral state transitions of black hole candidates could be explained either by varying the outer boundary of the CENBOL, which also happens to be the inner edge of the Keplerian disk, or by changing the central density of the CENBOL which is governed by the rate of the sub-Keplerian flow. We confirm the conclusions of the previous the- oretical studies that the interplay between the intensity of the soft photons emitted by the Keplerian flow and the optical depth and electron temperature of the Comptonizing cloud is responsible for the state transitions in a black hole.

description: We study two weighted graph coloring problems, in which one assigns $q$ colors to the vertices of a graph such that adjacent vertices have different colors, with a vertex weighting $w$ that either disfavors or favors a given color. We exhibit a weighted chromatic polynomial $Ph(G,q,w)$ associated with this problem that generalizes the chromatic polynomial $P(G,q)$. General properties of this polynomial are proved, and illustrative calculations for various families of graphs are presented. We show that the weighted chromatic polynomial is able to distinguish between certain graphs that yield the same chromatic polynomial. We give a general structural formula for $Ph(G,q,w)$ for lattice strip graphs $G$ with periodic longitudinal boundary conditions. The zeros of $Ph(G,q,w)$ in the $q$ and $w$ planes and their accumulation sets in the limit of infinitely many vertices of $G$ are analyzed. Finally, some related weighted graph coloring problems are mentioned.

description: For a circular magnetic nanodot in a vortex ground state we study how the critical velocity $v_c$ of the vortex core reversal depends on the magnitude $H$ of a bias magnetic field applied perpendicularly to the dot plane. We find that, similarly to the case $H$ = 0, the critical velocity does not depend on the size of the dot. The critical velocity is dramatically reduced when the negative (i.e. opposite to the vortex core direction) bias field approaches the value, at which a \emph{static} core reversal takes place. A simple analytical model shows good agreement with our numerical result.

title: Automated Comprehensiveness: Sectional Practices and the Misuse of Revit
Creators: name: Garcia Fritz, Jessica
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: All architectural drawings leave gaps in information. Drawing sets leave the impression that a combination of drawing types is comprehensive, that more information is better, but gaps always exist. In generating architecture, these gaps serve as opportunities for ambiguity, speculation, and exploration. The introduction of BIM in the late twentieth century and its more ubiquitous application in Autodesk’s 2004 release of Revit, challenged these previous notions of orthographic comprehensiveness as many images could be output from a single digital model. As representational types, plans, sections, elevations, and details did not disappear. Yet, the historic and conceptual practice for generating architecture through them started to. In Revit, the particular disappearance of sectional practices has been impacted by the automation of the section cut. What is lost when section cuts are automated through a digital tool like Revit and how can the tool be used to support sectional practices once again? The studio work presented in this paper focuses on the ontological transition from orthography to BIM, the impacts of automated processes, and the role of implementing sectional practices in a post- orthographic setting by critically examining specific tools and commands used in Revit. Ultimately, the work exemplifies a pedagogical approach that stems from the “misuse” of Revit as an archaeological and generative sectional tool for exploring gaps in information.

description: Exact analytic solutions are obtained in three-body problem for the scattering of light particle on two fixed centers in the case when pair potentials have a separable form. Solutions show an appearance of new three-body resonance states that depend on distance between two fixed centers. In the case when two-body neutron-nucleus amplitudes have the Breit-Wigner's form and heavy nuclei fixed in nodes of crystalline lattice widths of new resonance states can be equal to zero at certain values of the distance. It gives the possibility of transitions between three-body resonance states connected with process of electron capture by proton with formation of neutron and emission of neutrino. This exoenergic process leading to the cooling of star without nuclear reactions is discussed.

Quadrupole transient effects and a super-regenerative spectrometer
Creators: name: Sheikh, Aftab Ahmad
Publisher: name: University of British Columbia
Year: 2011

description: A field modulated super-regenerative spectrometer was constructed. The theory of its operation was developed and put to test by observing the pure quadrupole resonance of Chlorine 35 in Para - di-chlorobenzene powder at room temperature. The spectrometer's operation is closely related to the quadrupole transient effects. So another experiment was done to measure the amplitude and the decay time constant of Free Induction Signal in Para-di-chlorobenzene as a function of pulse width and magnetic field, using a pulsed r.f. transmitter, constructed for this purpose, The results of this experiment were then applied to the theory of the spectrometer to explain its behaviour.

Geometry and Symmetry Structures in 2T Gravity

subject: FOS: Physical sciences

description: 2T-gravity in d+2 dimensions predicts 1T General Relativity (GR) in d dimensions, augmented with a local scale symmetry known as the Weyl symmetry in 1T field theory. The emerging GR comes with a number of constraints, particularly on scalar fields and their interactions in 1T field theory. These constraints, detailed in this paper, are footprints of 2T-gravity and could be a basis for testing 2T-physics. Some of the conceptually interesting consequences of the "accidental" Weyl symmetry include that the gravitational constant emerges from vacuum values of the dilaton and other Higgs-type scalars and that it changes after every cosmic phase transition (inflation, grand unification, electroweak phase transition, etc.). We show that this consequential Weyl symmetry in d dimensions originates from coordinate reparametrization, not from scale transformations, in the d+2 spacetime of 2T-gravity. To recognize this structure we develop in detail the geometrical structures, curvatures, symmetries, etc. of the d+2 spacetime which is restricted by a homothety condition derived from the action of 2T-gravity. Observers that live in d dimensions perceive GR and all degrees of freedom as shadows of their counterparts in d+2 dimensions. Kaluza-Klein (KK) type modes are removed by gauge symmetries and constraints that follow from the 2T-gravity action. However some analogs to KK modes, which we call "prolongations" of the shadows into the higher dimensions, remain but they are completely determined, up to gauge freedom, by the shadows in d dimensions.

description: The electron linear accelerators driving modern X‐ray free‐electron lasers can emit intense, tunable, quasi‐monochromatic terahertz (THz) transients with peak electric fields of V Å−1 and peak magnetic fields in excess of 10 T when a purpose‐built, compact, superconducting THz undulator is implemented. New research avenues such as X‐ray movies of THz‐driven mode‐selective chemistry come into reach by making dual use of the ultra‐short GeV electron bunches, possible by a rather minor extension of the infrastructure.
First Neutrino Point-Source Results From the 22-String IceCube Detector

description: We present new results of searches for neutrino point sources in the northern sky, using data recorded in 2007-08 with 22 strings of the IceCube detector (approximately one-fourth of the planned total) and 275.7 days of livetime. The final sample of 5114 neutrino candidate events agrees well with the expected background of atmospheric muon neutrinos and a small component of atmospheric muons. No evidence of a point source is found, with the most significant excess of events in the sky at 2.2 sigma after accounting for all trials. The average upper limit over the northern sky for point sources of muon-neutrinos with E^-2 spectrum is E^2 Phi_nu_mu < 1.4x10^-11 TeV cm^-2 s^-1, in the energy range from 3 TeV to 3 PeV, improving the previous best average upper limit by the AMANDA-II detector by a factor of two.

An investigation of the noise signals associated with current measurement in a pulsed discharge circuit
Creators: name: Daughney, Cecil Charles
Publisher: name: University of British Columbia
Year: 2011

description: A Rogowski coil has been used for the measurement of a pulsed discharge current. The frequency response of the coil is discussed, and a method which extends this response to higher frequencies (100 Mc/s) is described. It has been found that the noise signals associated with the measurement of a pulsed discharge current are due principally to the electromagnetic radiation from the spark gap switches which are required in such a circuit. The radiation depends upon the breakdown mechanism of the spark gap, and its effect upon the measuring circuit can be minimized by making use of damping, resistors in series with the triggering sparks, shielded cables in the measuring circuit, and careful grounding of the discharge circuit. The noise signal on the current wave form can be completely eliminated by altering the spark gap geometry of the open air spark gap switch.
title: Structures for Relief & Resiliency: Enhancing Creative Applications of Technical Acumen through Constrained Conditions
Creators: name: WHITEHEAD, ROBERT
Publisher: name: University of Mass Amherst
Year: 2019

description: The design of places, objects, and experiential operations are of great importance to the relief, recovery and rebuilding efforts that affect millions of people each year. Proactively designing for these scenarios requires a more than just sensitivity to the vexing nature of the people and their problems. The inter-disciplinary teams that assist in these efforts must be able to translate these activities into solutions that have insights into the structural, material, and construction considerations. Without these qualities, the tangible, useful, and deployable solutions could be marginalized until they become the lowest common denominator of design solutions.

The value of design is largely excluded from the operational considerations. Surprisingly, the manuals used by these agencies have very little, if any, information about the actual design standards for these necessary resources of food, water, shelter, etc. Design solutions, and the associated technical acumen necessary to create these solutions, are un-necessarily absent.

Addressing these challenges educationally also presents challenges. The multi-faceted nature of the problems, the constantly changing sites and users, and the diverse teams of experts needed often excludes this work from design studios or building technology courses—or worse, the complexity of the issues are marginalizes as simply a search for a “better” shelter.

This paper will argue that the constrained conditions related to disaster relief and resiliency are ideal topics for building technology educators as they amplify the importance of the tools, design tactics, and technical principles that are integrated into the process and they create an inherent evaluative standards for performance assessment (i.e., maximized material utilization, integration with means of production / deployment, and resiliency).

This paper will describe several projects that have been developed in the last few years by an inter-disciplinary team of students in the College of Design at Iowa State University as part of a design-build option studio called, Structures in Service: Design for Relief and Resiliency. This course’s activities are based on the premise that relief and resiliency efforts can be meaningfully improved by a dedicated group of integrated designers that are able to leverage the benefits of contemporary design and production tools towards these efforts.
Generalization of the Poisson kernel to the superconducting random-matrix ensembles

description: We calculate the distribution of the scattering matrix at the Fermi level for chaotic normal-superconducting systems for the case of arbitrary coupling of the scattering region to the scattering channels. The derivation is based on the assumption of uniformly distributed scattering matrices at ideal coupling, which holds in the absence of a gap in the quasiparticle excitation spectrum. The resulting distribution generalizes the Poisson kernel to the nonstandard symmetry classes introduced by Altland and Zirnbauer. We show that unlike the Poisson kernel, our result cannot be obtained by combining the maximum entropy principle with the analyticity-ergodicity constraint. As a simple application, we calculate the distribution of the conductance for a single-channel chaotic Andreev quantum dot in a magnetic field.

Surfactant Monolayer Bending Elasticity in Lipase Containing Bicontinuous Microemulsions

description: Lipase-catalyzed reactions offer many advantages among which a high degree of selectivity combined with the possibility to convert even non-natural substrates are of particular interest. A major drawback in the applicability of lipases in the conversion of synthetically interesting, non-natural substrates is the substantial insolubility of such substrates in water. The conversion of substrates, natural or non-natural, by lipases generally involves the presence of a water–oil interface. In the present paper, we exploit the fact that the presence of lipases, in particular the lipase from Candida antarctica B (CalB), changes the bending elastic properties of a surfactant monolayer in a bicontinuous microemulsion consisting of D2O/NaCl -n-(d)-octane-pentaethylene glycol monodecyl ether (C10E5) in a similar manner as previously observed for amphiphilic block-copolymers. To determine the bending elastic constant, we have used two approaches, small angle neutron scattering (SANS) and neutron spin echo (NSE) spectroscopy. The time-averaged structure from SANS showed a slight decrease in bending elasticity, while on nanosecond time scales as probed with NSE, a stiffening has been observed, which was attributed to adsorption/desorption mechanisms of CalB at the surfactant monolayer. The results allow to derive further information on the influence of CalB on the composition and bending elasticity of the surfactant monolayer itself as well as the underlying adsorption/desorption mechanism.
A Model of Magnetic Braking of Solar Rotation That Satisfies Observational Constraints
Creators: name: Denissenkov, Pavel A.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The model of magnetic braking of solar rotation considered by Charbonneau & MacGregor (1993) has been modified so that it is able to reproduce for the first time the rotational evolution of both the fastest and slowest rotators among solar-type stars in open clusters of different ages, without coming into conflict with other observational constraints, such as the time evolution of the atmospheric Li abundance in solar twins and the thinness of the solar tachocline. This new model assumes that rotation-driven turbulent diffusion, which is thought to amplify the viscosity and magnetic diffusivity in stellar radiative zones, is strongly anisotropic with the horizontal components of the transport coefficients strongly dominating over those in the vertical direction. Also taken into account is the poloidal field decay that helps to confine the width of the tachocline at the solar age. The model's properties are investigated by numerically solving the azimuthal components of the coupled momentum and magnetic induction equations in two dimensions using a finite element method

title: Bridging the Gap between Architecture and Engineering: a Transdisciplinary Model for a Resilient Built Environment
Creators: name: Laboy, Michelle

Publisher: name: University of Mass Amherst
Year: 2019

description: As the focus of environmental engineering increasingly shifts to landscape-based, decentralized solutions to energy and water; and as architecture increasingly shifts its attention to resilience, ecological connectivity and independence from centralized infrastructure, these two disciplines find themselves closer in scale than before. This paper presents a collaborative project between upper level architecture and environmental engineering students focused on the design of sustainable and integrated water systems. Critical features of transdisciplinarity included: the engagement of stakeholders in the process at multiple moments; the speculative nature of working on very distant futures, the multi-scalar requirements of the collaboration, and the expectation of balancing quantitative and qualitative performance criteria. The curriculum was successful by many measures of work quality and impact. Students reflected on expectations and outcomes at two points of the semester, providing insights on challenges and opportunities. Relying on a shared responsibility for the project and well-aligned touchpoints, rather than daily- integrated studio-format, overcomes administrative constraints, but made misalignments more evident. While initially students had higher expectations of learning about the other discipline’s role than about their own, later results clearly show many more thought they had learned more about their own discipline, and expressed more confidence on their joint work. This is an encouraging finding about the power of transdisciplinary educational experiences.

Resolution and line shape in scintillation counters
Creators: name: Takhar, P. S.
Publisher: name: University of British Columbia
Year: 2011

description: An experimental study has been made of a number of factors that determine the pulse height resolution of Scintillation Counters. A statistical model is developed from which an analytic expression for the ideal line shape is obtained. Excellent agreement is found with observations using an artificial light pulser. An attempt to understand the noise spectra, exponential and non exponential under various conditions, has been made. A comparison is made between non crystalline organic scintillators and sodium iodide crystals of similar sizes. It is shown that for gamma-ray detection an important contribution to the line width originates with variations in the light collection efficiency from different regions of the scintillators.

Theory of Inelastic Electron Tunneling from a Localized Spin in the Impulsive Approximation

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: A simple expression for the conductance steps in the inelastic electron tunneling from spin excitations in a single magnetic atom adsorbed on a non-magnetic metal surfaces is derived. The inelastic coupling between the tunneling electron and the spin is via the exchange coupling and is treated in an impulsive approximation using the Tersoff-Hamann approximation for the tunneling between the tip and the sample. Our results for conductance steps justify the analysis carried out by Hirjebedin et al. [Science 317, 1199 (2007)] of observed step-like conductances by inelastic electron tunneling from spin excitations in a single magnetic adatom using a simple spin matrix element. In addition, our result gives a simple expression for the magnitudes of conductance steps and their lateral spatial variation with respect to the tip position, which can be calculated directly from spin-polarized wave functions at the Fermi level of the sample.
title: Open Pedagogy for Teaching Structures
Creators: name: Dermody, Robert
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: There is great potential to improve student engagement and retention by using open resources and pedagogies to teach structures. Open Educational Resources, OER, as defined by OER Commons are “…teaching and learning materials that you may freely use and reuse at no cost, and without needing to ask permission”. Open Pedagogy is more difficult to define, but Wiley states that “Open pedagogy is that set of teaching and learning practices only possible in the context of the free access and 5R permissions characteristic of open educational resources.” 2 The “5R permissions” refers to the fundamental basis of sharing open content that allows anyone to Retain, Reuse, Revise, Remix, or Redistribute the content of the resource in question.

After teaching structures for many years, using several different textbooks, with varying results in student engagement and learning outcomes, the author decided to investigate/develop open pedagogies to use in teaching fundamental structural concepts. This paper will focus on the author’s recent experiences in introducing open pedagogies into an existing, second- year, introductory structures course. The primary goal of this experiment was to improve students’ retention of course content and engage them more directly in their coursework by challenging them to find, create and share open content. Another goal was to guide students in creating documents containing pertinent structural design information that they could maintain for use in their future structures courses and design studios. Students were required to create their own websites to store and share their work in the course. This exercise exposed students to the “5R’s” of open content, at a relatively small scale. The course goals and context in which open resources and pedagogy were used will be explained and described. Future potentials for using open pedagogies to teach structures will also be discussed.

description: Results of the first ab initio simulations of InN/GaN multiquantum well (MQW) system are presented. The DFT results confirm the presence of the polarization charge at InN/GaN interfaces, i.e. at polar InN/GaN heterostructures. These results show the potential jumps which is related to the presence of dipole layer at these interfaces. An electrostatic polarization analysis shows that the energy minimum condition can be used to obtain the field in InN/GaN system, employing standard polarization parameters. DFT results are in good agreement with polarization data confirming the existence of electric field leading to separation of electron and holes in QWs and emergence of Quantum Confined Stark Effect (QCSE).

The objective of DEAR is to perform a 1% measurement of the K_α line shift due to the strong interaction in kaonic hydrogen.  A measurement will also be performed on kaonic deuterium for the first time. The aim is to investigate low-energy  KN physics and to understand SU(3) chiral symmetry breaking. The setup takes advantage of the unique features of the "kaon beam" from the f decay in DAFNE; of a low-temperature pressurized gaseous target; and of a detector for soft X rays- the Charge-Coupled Device (CCD) - characterized by a good resolution and by an unprecedented background rejection capability. The DEAR experiment represents a major effort in the study of low energy  KN interactions and has the potential to produce a breakthrough in the field.

description: SStarting from nonlinear realizations of the partially broken central-charge extended N=4 and N=8 Poincar\'e supersymmetries in D=4, we derive the superfield equations of N=2 and N=4 Born-Infeld theories. The basic objects are the bosonic Goldstone N=2 and N=4 superfields associated with the central charge generators. By construction, the equations are manifestly N=2 and N=4 supersymmetric and enjoy covariance under another nonlinearly realized half of the original supersymmetries. They provide a manifestly worldvolume supersymmetric static-gauge description of D3-branes in D=6 and D=10. For the N=2 case we find, to lowest orders, the equivalence transformation to the standard N=2 Maxwell superfield strength and restore, up to the sixth order, the off-shell N=2 Born-Infeld action with the second hidden N=2 supersymmetry.

AbstractMobocertinib (EXKIVITY™) is a first-in-class EGFR tyrosine kinase inhibitor being developed for the treatment of EGFR exon 20 insertion (EGFRex20ins) -positive non-small cell lung cancer (NSCLC). Based on efficacy in patients whose disease had progressed on or after platinum-based therapy in a phase I/II trial, mobocertinib was recently granted accelerated approval in the USA in this indication. The drug is also being assessed for marketing approval in various other countries and territories including the EU and China. This article summarizes the milestones in the development of mobocertinib leading to this first approval in the USA for locally advanced or metastatic EGFRex20ins-positive NSCLC that has progressed on or after platinum-based chemotherapy.

description: We report on a search for inclusive production of squarks and gluinos in ppbar collisions at sqrt{s}=1.96 TeV, in events with large missing transverse energy and multiple jets of hadrons in the final state. The study uses a CDF Run II data sample corresponding to 2 fb-1 of integrated luminosity. The data are in good agreement with the standard model predictions, giving no evidence for any squark or gluino component. In an R-parity conserving minimal supergravity scenario with A_0 = 0, mu < 0 and tanbeta = 5, 95% C.L. upper limits on the production cross sections in the range between 0.1 pb and 1 pb are obtained, depending on the squark and gluino masses considered. For gluino masses below 280 GeV/c2, arbitrarily large squark masses are excluded at the 95%C.L., while for mass degenerate gluinos and squarks, masses below 392 GeV/c2 are excluded at the 95% C.L.

title: Integration of Building Energy Modeling (BEM) and Building Information Modeling (BIM): Workflows and Case Study

description: Building Energy Modeling (BEM) intends to quantify buildings’ energy performance to help designers and architects better understand the environmental impacts of their decisions. Building Information Modeling (BIM) refers to a digital, model-based representation, where information about building design can be shared among different stakeholders and used during all stages of buildings’ lifecycle. The purpose of this research was to investigate integration of BEM and BIM, using two analysis tools. Green Building Studio (GBS) and Sefaira are two performance analysis software programs, which can be used both in the form of BIM plug-in/built-in tools, as well as web applications to analyze and quantify energy performance of buildings. To capture their level of integration with BIM, an existing Campus Recreation Building on UMass Amherst campus was used as a case study to evaluate modeling processes, requirements, and workflows. Comparative analysis between modeled and actual energy consumption data was also performed to analyze accuracy of the different simulation programs. This paper discusses each tool capabilities and drawbacks in providing accurate energy analysis procedures and results.

Long-range energy transfer in proteins

description: Proteins are large and complex molecular machines. In order to perform their function, most of them need energy, e.g. either in the form of a photon, like in the case of the visual pigment rhodopsin, or through the breaking of a chemical bond, as in the presence of adenosine triphosphate (ATP). Such energy, in turn, has to be transmitted to specific locations, often several tens of Angstroms away from where it is initially released. Here we show, within the framework of a coarse-grained nonlinear network model, that energy in a protein can jump from site to site with high yields, covering in many instances remarkably large distances. Following single-site excitations, few specific sites are targeted, systematically within the stiffest regions. Such energy transfers mark the spontaneous formation of a localized mode of nonlinear origin at the destination site, which acts as an efficient energy-accumulating centre. Interestingly, yields are found to be optimum for excitation energies in the range of biologically relevant ones.

description: Executive Summary

Micro- and nanoplastics (MNPs), ubiquitous byproducts of global plastic pollution, pose significant potential risks to human health. These particles, often smaller than 5 mm, are increasingly found in food, water, air, and human tissues. Research underscores their ability to traverse biological barriers, accumulate in organs, and disrupt cellular and systemic functions. MNPs raise concerns about long-term adverse health effects. This 3rd PlasticsFatE policy brief examines current findings on MNP exposure pathways, biological interactions, and potential health impacts, emphasizing the urgent need for policy interventions to mitigate possible risks.

description: The goal of an integrative building design studio is for students to develop and prove the capacity to integrate different technical and possibly legal and financial considerations into their architectural projects. In this context, it is most important for the students to learn how to maintain a clear conceptual strategy that can serve as a ‘pièce de résistance’ against the multitude of different pressures, providing a larger framework for design decisions. This presentation discusses a series of projects where this ‘pièce de résistance’ was based on the design potentials of advanced pre-cast concrete construction. Tectonic concerns, with a focus on structure, construction, and materiality were foregrounded in the studio. Meanwhile, other aspects such as program and building form were intentionally pushed to the background, offering a design methodology where the architectural form and expression emerges from working through the possibilities of the material and construction processes.

Throughout the 20th and 21st century concrete has been the main material used in construction.1 Although the use of this material dates back to ancient Rome, it is also a material that has time and time again been adopted and transformed by new technological innovations. Over the last decades, there were extensive improvements in many aspects of concrete technology, such as new mixtures or improvements in reinforcement, which allow for concrete to be stronger, more durable, highly insulating, or even ductile. And the reduction of the cement content, through the use of reactive industrial by-products, such as fly ash or silica fume, provide sizable reduction of the embodied energy in concrete construction.2 To create a framework that allows for material speculations in studio, the students were given very specific parameters for the typology of the building and a focused on prefabrication. Initial excises asked the students to carefully document construction processes in a series of case studies as well as design task to translate an existing joint, at the scale of furniture, into two cement cast pieces. The results of the exercise were then used by the students to develop a building strategy that is constructed ‘from the inside out’, contextualizing the program and the site through the constructive system and formal language that emerged from the translation of their initial studies into a more robust architectural project.
