Designing note-taking for meaningful learning
Creators: name: Hsia, Jesse
Publisher: name: Carnegie Mellon University
Year: 2012
Subjects: Design

description: Technology can have an immense impact on how people perceive, process, and learn new information. Technology-focused research is being conducted in the area of note-taking, as it is an activity most students perform. However, much of this work focuses on improving access, efficiency, and interactivity without emphasis on how technology can support learning. Thus, this project investigates the design of note-taking tools and their contexts of use as a means of helping people perceive, process, and learn information in educational contexts. The outcome of this investigation realizes an opportunity for a new device and software experience that is designed to aid learning in the information era. Kekulé is a digital notebook for the information era developed as a result of this thesis investigation. It is designed to cater to different learning preferences and help move individuals move through the cycle of learning in meaning-making, abstract conceptualization, experimentation, and transforming knowledge to new understanding.

description: The Chapman-Kolmogorov equation with fractional integrals is derived. An integral of fractional order is considered as an approximation of the integral on fractal. Fractional integrals can be used to describe the fractal media. Using fractional integrals, the fractional generalization of the Chapman-Kolmogorov equation is obtained. From the fractional Chapman-Kolmogorov equation, the Fokker-Planck equation is derived.

description: A star enshrouded in a Dyson sphere with high covering fraction may manifest itself as an optically subluminous object with a spectrophotometric distance estimate significantly in excess of its parallax distance. Using this criterion, the Gaia mission will in coming years allow for Dyson-sphere searches that are complementary to searches based on waste-heat signatures at infrared wavelengths. A limited search of this type is also possible at the current time, by combining Gaia parallax distances with spectrophotometric distances from ground-based surveys. Here, we discuss the merits and shortcomings of this technique and carry out a limited search for Dyson-sphere candidates in the sample of stars common to Gaia Data Release 1 and RAVE Data Release 5. We find that a small fraction of stars indeed display distance discrepancies of the type expected for nearly complete Dyson spheres. To shed light on the properties of objects in this outlier population, we present follow-up high-resolution spectroscopy for one of these stars, the late F-type dwarf TYC 6111-1162-1. The spectrophotometric distance of this object is about twice that derived from its Gaia parallax, and there is no detectable infrared excess. While our analysis largely confirms the stellar parameters and the spectrophotometric distance inferred by RAVE, a plausible explanation for the discrepant distance estimates of this object is that the astrometric solution has been compromised by an unseen binary companion, possibly a rather massive white dwarf ($\approx 1\ M_\odot$). This scenario can be further tested through upcoming Gaia data releases.

description: We use a recent classification of non-degenerate quasihomogeneous polynomials to construct all Landau-Ginzburg (LG) potentials for N=2 superconformal field theories with c=9 and calculate the corresponding Hodge numbers. Surprisingly, the resulting spectra are less symmetric than the existing incomplete results. It turns out that models belonging to the large class for which an explicit construction of a mirror model as an orbifold is known show remarkable mirror symmetry. On the other hand, half of the remaining 15\% of all models have no mirror partners. This lack of mirror symmetry may point beyond the class of LG-orbifolds.

description: We study the coupling between collective variables of atomic spin and light polarization in an ensemble of cold 87Rb probed with polarized light. The effects of multiple hyperfine levels manifest themselves as a rank-2 tensor polarizability, whose irreducible components can be selected by means of probe detuning. The D1 and D2 lines of Rb are explored and we identify different detunings which lead to Hamiltonians with different symmetries for rotations. As possible applications of these Hamiltonians, we describe schemes for spin squeezing, quantum cloning, quantum memory, and measuring atom number.

Intestinal Obstruction in a Steer
Creators: name: Washburn, Kevin E.
Publisher: name: The Bovine Practitioner
Year: 2019

description: A 550 lb steer was presented with a history of anorexia, depression, "stiffness", and scant feces. Physical examination revealed a normal rectal temperature, increased heart and respiratory rates and abdominal distension. The initial attempt to examine the steer per rectum was unsuccessful. Laboratory findings were normal except for increased protein in the abdominal fluid. A second examination of the abdomen per rectum revealed a tight, fibrous band extending from the right internal inguinal ring to the pelvic floor, which had entrapped portions of the small intestine. An exploratory laparotomy was done using the right paralumbar fossa approach. The tight fibrous band was found to be a remnant of the vas deferens. The band was exteriorized and cut with scissors. Post-operative recovery was uneventful and the steer was marketed months later at his projected market weight.

description: This thesis considers the structural characteristics of online criminal networks from a technical and an economic perspective. Through large-scale measurements, we empirically describe some salient elements of the online criminal infrastructures, and we derive economic models characterizing the associated monetization paths enabling criminal profitability. This analysis reveals the existence of structural choke points: components of online criminal operations being limited in number, and critical for the operations’ profitability. Consequently, interventions targeting such components can reduce the opportunities and incentives to engage in online crime through an increase in criminal operational costs, and in the risk of apprehension. We define a methodology describing the process of distilling the knowledge gained from the empirical measurements on the criminal infrastructures towards identifying and evaluating appropriate countermeasures. We argue that countermeasures, as defined in the context of situational crime prevention, can be effective for a long-term reduction in the occurrence of online crime.

description: We introduce a new type of boundary conditions, {\it smooth boundary conditions}, for numerical studies of quantum lattice systems. In a number of circumstances, these boundary conditions have substantially smaller finite-size effects than periodic or open boundary conditions. They can be applied to nearly any short-ranged Hamiltonian system in any dimensionality and within almost any type of numerical approach.

description: We consider the extended Hubbard model and introduce a corresponding Heisenberg-like problem written in terms of spin operators. The derived formalism is reminiscent of Anderson's idea of the effective exchange interaction and takes into account nonlocal correlation effects. The results for the exchange interaction and magnetic susceptibility are expressed in terms of single-particle quantities, which can be obtained efficiently in realistic calculations of multiband systems. In the strongly spin-polarized limit, when the local magnetic moment is well-defined, the exchange interaction reduces to a standard expression of the density functional theory that has been successfully used in practical calculations of magnetic properties of real materials.

description: We study evolution of dark matter substructures, especially how they lose the mass and change density profile after they fall in gravitational potential of larger host halos. We develop an analytical prescription that models the subhalo mass evolution and calibrate it to results of N-body numerical simulations of various scales from very small (Earth size) to large (galaxies to clusters) halos. We then combine the results with halo accretion histories, and calculate the subhalo mass function that is physically motivated down to Earth-mass scales. Our results --- valid for arbitrary host masses and redshifts --- show reasonable agreement with those of numerical simulations at resolved scales. Our analytical model also enables self-consistent calculations of the boost factor of dark matter annhilation, which we find to increase from tens of percent at the smallest (Earth) and intermediate (dwarfs) masses to a factor of several at galaxy size, and to become as large as a factor of $\sim$10 for the largest halos (clusters) at small redshifts. Our analytical approach can accommodate substructures in the subhalos (sub-subhalos) in a consistent framework, which we find to give up to a factor of a few enhancement to the annihilation boost. Presence of the subhalos enhances the intensity of the isotropic gamma-ray background by a factor of a few, and as the result, the measurement by Fermi Large Area Telescope excludes the annihilation cross section greater than $\sim$$4\times 10^{-26}$ cm$^3$ s$^{-1}$ for dark matter masses up to $\sim$200 GeV.

Publisher: name: The Bovine Practitioner
Year: 2019

description: On May 25, 1999, a storm producing hail approximately 1 ¾ to 3¾ inches in diameter crossed over a feed yard. On four occasions following the storm, 409 carcasses from six pens were observed at an abattoir. On day 1, 29 carcasses were examined at the abattoir and in the grading cooler. On days 10, 15, and 49, additional cattle (n = 117, 173, and 90, respectively) were examined at the abattoir only. On day 16 following the first storm, a second storm, producing approximately 1 ¾-inch-diameter hail, crossed over the feed yard. Bruises were classified into three size categories, into short- and long-duration categories, and location was recorded. One hundred, 85, 54, and 44% of the carcasses exhibited bruises on days 1, 10, 15, and 49, respectively. On days 1, 10, 15, and 49, 100, 98, 65, and 27% of bruises were classified as short-duration. Multiple bruises were observed on 100, 75, 42, and 16% of carcasses on days 1, 10, 15, and 49, respectively. Storms producing hail approximately 3¾ inches in diameter have the potential to cause extensive bruising in cattle in open feed yards. Cattle sold within 15 days of such storms may experience significant hail-associated carcass trim loss, but by day 49 bruising appears to return to baseline levels.

description: The pairing symmetry of an effective Hamiltonian for interacting fermions on a twisted bilayer graphene superlattice is studied with the determinant quantum Monte Carlo method. The model has the symmetry of a triangle lattice and a nearly-flat low energy band, features which underlie the magic-angle twisted bilayer graphene superlattice. We show that the low temperature phase is insulating at half-filling, even for relatively weak interactions. The natures of the spin and pairing correlations upon doping are determined, and exhibit an electron-hole asymmetry consistent with experiment. Among the pairing symmetries allowed, we demonstrate that the dominating channels are $d$-wave, opening the possibility of condensation into an unconventional $d_{x^2-y^2}+id_{xy}$ phase, which is characterized by an integer topological invariant and gapless edge states.

The dual setting of polytopes generated by random halfspaces is also investigated.

Designing Medical Devices for Healing Interactions: A Dialysis Case Study

Year: 2015
Subjects: Design

description: The purpose of this research is to explore the interactions between patients and life-saving medical devices, to understand how the design of these machines can be improved to promote wellness and provide a better quality of life. Life-saving medical devices such as dialysis machines, heart pumps, and artificial lungs are amazing pieces of technology that perform the incredible function of sustaining and extending life. However, aside from meeting the patient’s medical needs, it is also important to consider how interactions with these devices impact a patient’s psychological well-being and overall quality of life. One of the key insights that came from my research was the idea that complex, life-sustaining medical devices may unintentionally contribute to a patient’s feelings of being out of control of not only their body but also their life. For many people this can lead to depression, despite the fact that their physical medical condition is being successfully treated. As a result, I explored a wearable design concept for a patient-facing dashboard, which would help to alleviate some of these effects by (1) communicating to patients what is happening physically within their bodies, (2) promoting a sense of ownership over their bodies and their treatment, and (3) inspiring a feeling of control over their treatment outcomes and their lives.

description: Modifications of the properties of jets in PbPb collisions, relative to those in pp collisions, are studied at a nucleon-nucleon center-of-mass energy of $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV via correlations of charged particles with the jet axis in relative pseudorapidity ($Δη$), relative azimuth ($Δϕ$), and relative angular distance from the jet axis $Δ\mathrm{r} = \sqrt{{(Δη)^{2}+(Δϕ)^{2}}}$. This analysis uses data collected with the CMS detector at the LHC, corresponding to integrated luminosities of 404 $μ$b$^{-1}$ and 27.4 pb$^{-1}$ for PbPb and pp collisions, respectively. Charged particle number densities, jet fragmentation functions, and jet shapes are presented as a function of PbPb collision centrality and charged-particle track transverse momentum, providing a differential description of jet modifications due to interactions with the quark-gluon plasma.

Structure of Rod-like Polyelectrolyte-Surfactant Aggregates in Solution and in Adsorbed Layers

description: Polyelectrolyte-surfactant aggregates (PES) have diverse sets of properties, which could be controlled by a wide range of parameters, both within the aggregates themselves and the surrounding environment. The large portfolio of applications amplifies the need to understand them. A particular system of polyelectrolyte-surfactant aggregate, polycetyltrimethyl vinylbenzoate, denoted pC16TVB, which self-assembles in aqueous solution, is the main focus of the thesis. Its structure is the product of the balance between surfactant head groups – polyelectrolyte charge groups electrostatic interactions and surfactant tails – polyelectrolyte backbone hydrophobic interactions. At neutral solution pH, the structure is one of a core-shell cylinder, with the shell consisting of surfactant heads. The surfactant tails point toward the core center, while the polyelectrolyte also resides in the core, but remains close to the core-shell interface for charge neutralization. As the pH drops to 1.0, the balance is disrupted with the hydrophobic interaction being increasingly dominant while electrostatic interaction is reduced, and the structure transforms into a more commonly seen string-of-pearl, in which the polymer chain connects a series of spherical surfactant micelles. The solution properties are impacted accordingly, becoming viscoelastic while solubilizing 10 times more hydrophobic molecules. Treating the pC16TVB aggregate as a whole, its adsorption onto oxide nanoparticles surfaces has been analyzed, extended from a previous flat surface adsorption work. Aided by hydrophobic dyes as molecular trackers, the adsorbed thickness has been proven to be a function of the surface curvature, with less curve surface adsorbs more material. The dye loading remains intact after the adsorption, enabling the use of the aggregate as a delivery vehicle for hydrophobic materials in aqueous solution. The resulting adsorption of pC16TVB aggregate onto SiO2 surfaces has a core-shell sphere structure. Unlike for flat surfaces, in which the adsorption mechanism has been shown previously to consist of two main steps, with some dissociated surfactant molecules adsorbing head first via electrostatic attraction with the surface to create hydrophobic anchor points for further aggregate adsorption, the high bending energy cost and the low aggregate concentration (relative to the total sphere surface area) suspend the adsorption after the initial surfactant adsorption step

We show that there are regions in the SUSY-FCNC parameter space where the $A^0_1$ in the NMSSM can be used to explain the HyperCP events without contradicting all the existing constraints from the measurements of the kaon decays, and the constraints from the $K^0-\bar{K}^0$ mixing are automatically satisfied once the constraints from kaon decays are satisfied.

description: Humans interact with each other on a daily basis by developing and maintaining various social norms and it is critical to form a deeper understanding of how such norms develop, how they change, and how fast they change. In this work, we develop an evolutionary game-theoretic model based on research in cultural psychology that shows that humans in various cultures differ in their tendencies to conform with those around them. Using this model, we analyze the evolutionary relationships between the tendency to conform and how quickly a population reacts when conditions make a change in norm desirable. Our analysis identifies conditions when a tipping point is reached in a population, causing norms to change rapidly.

We quantify the residual spatial overlap between the two components by measuring three-body recombination losses for variable strength of the interspecies repulsion. A comparison with a numerical mean-field model highlights the importance of the kinetic energy term for the condensed bosons in maintaining the thin interface far into the phase-separated regime. Our results demonstrate a corresponding smoothing of the phase transition in a system of finite size.

Small Deviations from the R^1/4 Law, the Fundamental Plane, and Phase Densities of Elliptical Galaxies
Creators: name: Hjorth, Jens
name: Madsen, Jes
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)

description: The light profiles of elliptical (E) galaxies are known to display small systematic deviations (0.1-0.2 mag.) from the R^1/4 law. In this paper we show that the senses and amplitudes of these departures can be naturally accounted for by a simple distribution function constructed on the basis of statistical mechanics of violent relaxation. As a consequence, detailed light-profiles can be used to infer about the central potentials of E galaxies (the only free shape parameter of our model). Furthermore, the small deviations have recently been shown to correlate with luminosity, L. This observation entails a slight breaking of the generally assumed structural homology between E galaxies. Using our model we parametrize this broken homology by establishing a correlation between a suitably normalized central potential and luminosity. The non-homology means that a basic assumption in the interpretation of the Fundamental Plane (FP) breaks down, and with it the conclusions derived from it. Instead, by assuming that M/L is independent of luminosity, we derive a relation akin to the FP directly from our correlation. This implies that the FP may have a simple stellar dynamical origin. We can reproduce the observed Carlberg-Kormendy relation for the central phase-space densities (f_c) of E galaxies of identical structure, f_c = L^-2.35, but non-homology changes it to a much weaker dependence (f_c = L^-1.5 for constant M/L) which would imply that the central phase-space densities of ellipticals are comparable to those of spiral galaxies. Thus dissipationless merging is consistent with the FP, although HST observations, notably the presence of nuclear embedded disks, indicate that the assumptions behind our model break down for the nuclei of faint E galaxies in which dissipative processes seem to be important.

description: Systematized subject classification is essential for funding and assessing scientific projects. Conventionally, classification schemes are founded on the empirical knowledge of the group of experts; thus, the experts' perspectives have influenced the current systems of scientific classification. Those systems archived the current state-of-art in practice, yet the global effect of the accelerating scientific change over time has made the updating of the classifications system on a timely basis vertually impossible. To overcome the aforementioned limitations, we propose an unbiased classification scheme that takes advantage of collective knowledge; Wikipedia, an Internet encyclopedia edited by millions of users, sets a prompt classification in a collective fashion. We construct a Wikipedia network for scientific disciplines and extract the backbone of the network. This structure displays a landscape of science and technology that is based on a collective intelligence and that is more unbiased and adaptable than conventional classifications.

description: Following the reasoning of Claudson and Halpern, it is shown that "fifth-time" stabilized quantum gravity is equivalent to Langevin evolution (i.e. stochastic quantization) between fixed non-singular, but otherwise arbitrary, initial and final states. The simple restriction to a fixed final state at $t_5 \rightarrow \infty$ is sufficient to stabilize the theory. This equivalence fixes the integration measure, and suggests a particular operator-ordering, for the fifth-time action of quantum gravity. Results of a numerical simulation of stabilized, latticized Einstein-Cartan theory on some small lattices are reported. In the range of cosmological constant $ł$ investigated, it is found that: 1) the system is always in the broken phase $ \ne 0$; and 2) the negative free energy is large, possibly singular, in the vincinity of $ł= 0$. The second finding may be relevant to the cosmological constant problem.

Creators: name: Bird, Peter S.
Publisher: name: Carnegie Mellon University

Subjects: Design

description: I remember as a young child being fascinated with all forms of transportation: from the Walt Disney World monorails and shuttle buses, to Busy Boats, my favorite library picture book, to my first train ride, a 20-mile one-way trip on Amtrak that became the subject of my second-grade book fair masterpiece, The Great Day. Now, quite a number of years later, that fascination remains, manifesting itself in different ways, like getting excited when I get stopped by a passing train at a railroad crossing or riding the city bus to campus every day. Being an avid newspaper reader, I followed the long public process in the winter and spring of 2006–2007 as the Port Authority of Allegheny County, the public transit entity in Pittsburgh, identified ways to reduce costs to meet a multi-million dollar budget shortfall. Being a designer, one of the things that struck me was the Port Authority’s use of visuals to communicate what routes they proposed for elimination. These diagrams, one of which is shown in Figure 1, left something to be desired. It didn’t seem to communicate a clear message amidst all the visual clutter. I spent a few weeks trying out different variations and revisions of the diagram for a class in mapping and diagramming and thought that this area of design—user experience and complex information systems for transit—would be perfect for further study. In my preliminary review of current literature, I found studies of specific design improvements, such as a new bus map system in London (Horne, Roberts & Rose, 1986), historical reviews of iconic documents such as the London Underground diagram (Garland, 1994) and surveys of current practices by organizations such as the American Public Transportation Association (2007), an industry trade group, and the Transportation Research Board (1999). However, this research focused primarily on the document or artifact in question and only tangentially on rider information needs from an abstract perspective while ignoring the user experience. This essay will present the results of my observations and thoughts about the user experience of riders in public transportation systems. I will begin by defining a public transportation system and describing its various components and integration into the city’s transportation infrastructure. In the second section, I’ll describe users of these transit systems—the riders—and offer a series of categories and characteristics we can use to understand why they use public transportation. I’ll discuss how these riders use a public transportation system in section three, by offering a five-part model for a trip. Finally, in section four, I will analyze various aspects of the physical, printed artifacts transit systems distribute to the public to communicate what services they provide.

description: Abstract

This study examined the relationship between trade liberalization and economic growth in Nigeria between 1981 and 2022, using Johansen co-integration and Wald tests. The findings showed that the variables employed were co-integrated, leading to the long-run relationship among the variables.  The results revealed that the independent variables: net oil export (NOIEX), net non-oil export (NNOIEX), exchange rate (EXR) and foreign direct investment (FDI) have short-run impacts on the gross domestic product (GDP).  It is therefore recommended that government should not relent in her responsibility to ensure that both oil and non-oil trades in Nigeria are more encouraged, formulating policies to support its efficiency and profitability to enhance sustainable economic growth in the country.

K Band Microlensing of the Inner Galaxy
Creators: name: Gould, Andrew
Publisher: name: arXiv
Year: 1994
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Microlensing searches toward the inner galaxy $(|l|,|b|\leq 22.\hskip-2pt'5)$ have several major advantages. First, the event rate is strongly dominated by bulge-bulge lensing events where both the source and lens lie in the bulge. Second, these bulge-bulge events have very short time scales $t_e\sim 2\,$days and are therefore easily distinguished from the less frequent and much longer bulge-disk and disk-disk events. Third, since the optical depth is similar to that at higher impact parameters, while the events are shorter, the event rate is high $Γ\sim 3\times 10^{-7}\rm day^{-1}$. Fourth, because the Einstein rings are small, $r_e\sim 5\times 10^{12}\,$cm, and the source stars are large $r_s\gsim 10^{12}\,$cm, the lens will transit the face of the source for a significant fraction $(\sim 20\%)$ of events. For these transit events it will often be possible to measure a second lens parameter, the angular Einstein radius (or proper motion). In addition to the bulge-bulge events, the optical depth of the disk is $\sim 7$ times larger toward the inner Galaxy than toward Baade's Window. A microlensing search toward the inner Galaxy can be carried out by making frequent $(\sim4\,\rm day^{-1})$ K band images of a large area $\sim 0.5\,\rm deg^2$ to a depth of $K\sim 16$, and hence requires either a $1024^2$ infrared array on a dedicated 2m telescope or four such arrays on a 1m telescope.

description: Codes in finite projective spaces equipped with the subspace distance have been proposed for error control in random linear network coding. Here we collect the present knowledge on lower and upper bounds for binary subspace codes for projective dimensions of at most $7$. We obtain several improvements of the bounds and perform two classifications of optimal subspace codes, which are unknown so far in the literature.

description: We have observed a sample of 64 small diameter sources towards the central -6 degree < l< 6 degree, -2 degree < b < 2 degree of the Galaxy with the aim of studying the Faraday rotation measure near the Galactic Centre (GC) region. All the sources were observed at 6 and 3.6 cm wavelengths using the ATCA and the VLA. Fifty nine of these sources are inferred to be extragalactic. The observations presented here constitute the first systematic study of the radio polarisation properties of the background sources towards this direction and increases the number of known extragalactic radio sources in this part of the sky by almost an order of magnitude. Based on the morphology, spectral indices and lack of polarised emission, we identify four Galactic HII regions in the sample.

Experimental tests of the chiral anomaly magnetoresistance in the Dirac-Weyl semimetals Na$_3$Bi and GdPtBi

description: In the Dirac/Weyl semimetal, the chiral anomaly appears as an "axial" current arising from charge-pumping between the lowest (chiral) Landau levels of the Weyl nodes, when an electric field is applied parallel to a magnetic field $\bf B$. Evidence for the chiral anomaly was obtained from the longitudinal magnetoresistance (LMR) in Na$_3$Bi and GdPtBi. However, current jetting effects (focussing of the current density $\bf J$) have raised general concerns about LMR experiments. Here we implement a litmus test that allows the intrinsic LMR in Na$_3$Bi and GdPtBi to be sharply distinguished from pure current jetting effects (in pure Bi). Current jetting enhances $J$ along the mid-ridge (spine) of the sample while decreasing it at the edge. We measure the distortion by comparing the local voltage drop at the spine (expressed as the resistance $R_{spine}$) with that at the edge ($R_{edge}$). In Bi, $R_{spine}$ sharply increases with $B$ but $R_{edge}$ decreases (jetting effects are dominant). However, in Na$_3$Bi and GdPtBi, both $R_{spine}$ and $R_{edge}$ decrease (jetting effects are subdominant). A numerical simulation allows the jetting distortions to be removed entirely. We find that the intrinsic longitudinal resistivity $ρ_{xx}(B)$ in Na$_3$Bi decreases by a factor of 10.9 between $B$ = 0 and 10 T. A second litmus test is obtained from the parametric plot of the planar angular magnetoresistance. These results strenghthen considerably the evidence for the intrinsic nature of the chiral-anomaly induced LMR. We briefly discuss how the squeeze test may be extended to test ZrTe$_5$.

description: All-sky surveys for isolated continuous gravitational waves present a significant data-analysis challenge. Semicoherent search methods are commonly used to efficiently perform the computationally-intensive task of searching for these weak signals in the noisy data of gravitational-wave detectors such as LIGO and Virgo. We present a new implementation of a semicoherent search method, Weave, that for the first time makes full use of a parameter-space metric to generate banks of search templates at the correct resolution, combined with optimal lattices to minimize the required number of templates and hence the computational cost of the search. We describe the implementation of Weave and associated design choices, and characterize its behavior using semi-analytic models.
