Towards Photorealistic Dynamic Capture and Animation of Human Hair and Head

description: Realistic human avatars play a key role in immersive virtual telepresence. A human avatar needs to faithfully reflect human appearance to reach a high level of realism. Besides, a human avatar should also be drivable and express natural motions. Existing works have made significant progress in building drivable realistic face avatars, but they rarely include realistic dynamic hair despite its importance in human appearance. In pursuit of drivable, realistic human avatars with dynamic hair, we focus on the problem of automatically capturing and animating hair from multi-view videos. We first look into the problem of capturing the motion of the head with nearstatic hair. Because the hair has complex geometry, we use a neural volumetric representation that can be rendered efficiently. As a result, we achieve photorealistic capture of complex hairstyles by optimizing the representation with the gradient from the reconstruction loss on 2D via differentiable volumetric rendering. Then we extend the problem to capturing hair with dynamics. To accommodate the complexity introduced by the temporal dimension, data-priors on motion like optical flow and point flow are leveraged as additional supervision. To be more specific, we first perform tracking on hair strands with a data prior on motion. In the next step, we attach volumetric primitives to the tracked hair strands to learn the fine-level appearance and geometry via differentiable rendering. We further design a differentiable volumetric rendering algorithm with the optical flow to ensure temporal smoothness at a fine level. As a result, we achieve robust dynamic capture of hair with large motions. We then address the problem of building a hair dynamic model for generating novel animation. We present a two-stage pipeline to build a hair dynamic model in a data-driven manner. The first stage performs hair state compression using an autoencoder-as-a-tracker strategy. The second stage learns a hair dynamic model in a supervised manner using the hair state data from the first stage. The hair dynamic model enables in-the-wild animation of hair that performs hair state transitions conditioned on head motions and head relative gravity direction. In parallel to capturing and animating specific hairstyles, we explore the problem of how to efficiently capture diverse hair appearances. Hair plays a significant role in personal identity and the efficient creation of personalized avatars with decent hair is essential to individual usages. To handle the large intra-class variance in hair appearance and geometry, we present a universal hair appearance model that focuses on the similarity between different hairstyles in a local region. The model takes 3D-aligned features as input and learns a unified manifold of local hair appearance that adaptively generates appearance for hairstyles with diverse topologies.

description: Over the last decade, global air traffic has nearly doubled and with the growth of international travel and trade, comes the potential for the global transmission of infectious disease. This requires countries to have the capacity to respond to pandemic threats and for clear guidance on conducting risk assessments in an efficient and timely manner due to the dynamic nature of air travel. The COVID-19 pandemic has revealed disjointed risk assessment and containment measures across the globe underscoring the need for harmonious evidence-based protocols and guidance in order to respond to emerging viruses and potential pandemics more efficiently and effectively. The conduction of this quasi-systematic review aims to examine and address changes in the international public health and aircraft guidance for infectious disease containment measures related to air travel amidst the global COVID-19 pandemic. It intends to examine the changes in the methods, models, frameworks, and best practices since the 2009 European Centre for Disease Prevention and Control (ECDC) RAGIDA project (Risk Assessment and Guidance for Infectious Disease transmitted on Aircraft) that have shaped current responses to novel COVID-19.

description: How Scholars Write introduces academic writers—undergraduates, graduate students, and other researchers—to the often surprising realities of how seasoned scholars research and write. Writers who are newer to academic research may find the gap between their own writing and published writing daunting. Published writing often appears to present brilliant thinking with ease. However, behind the scenes, the scholars producing that published writing are themselves learning, experimenting, writing and rewriting (and rewriting again), asking for help, and sometimes running into road blocks. This book takes you behind the scenes of scholars’ writing in order to dispel the notion that only people born brilliant can be academic writers. Rather, successful scholars practice principled strategies that anyone can adopt in order to craft academic writing that matters. Though the book contains a fair amount of practical advice, this is not an advice book. Instead, our project here is to present a transparent, principled, research-based description of how scholars actually get things written. We offer here not unbreakable rules but a mindset, not formulas but tools and techniques.

description: We use the operator product expansion to derive exact results for the momentum distribution and the static structure factor at high momentum for a jellium model of electrons in both two and three dimensions. It is shown that independent of the precise state of the Coulomb system and for arbitrary temperatures, the asymptotic behavior is a power law in the momentum, whose strength is determined by the contact value of the pair distribution function $g(0)$. The power-law tails are quantum effects which vanish in the classical limit $\hbar \to 0$. A leading order virial expansion shows that the classical and the high-temperature limit do not agree.

description: A longstanding open problem in lambda calculus is whether there exist continuous models of the untyped lambda calculus whose theory is exactly the least lambda-theory lambda-beta or the least sensible lambda-theory H (generated by equating all the unsolvable terms). A related question is whether, given a class of lambda models, there is a minimal lambda-theory represented by it. In this paper, we give a general tool to answer positively to this question and we apply it to a wide class of webbed models: the i-models. The method then applies also to graph models, Krivine models, coherent models and filter models. In particular, we build an i-model whose theory is the set of equations satisfied in all i-models.

description: Yes, the photon. While a nonzero photon mass has been under experimental and theoretical study for years, the possible implication of a finite photon lifetime lacks discussion. The tight experimental upper bound of the photon mass restricts the kinematically allowed final states of photon decay to the lightest neutrino and/or particles beyond the Standard Model. We discuss the modifications of the well-measured cosmic microwave background spectrum of free streaming photons due to photon mass and lifetime and obtain model-independent constraints on both parameters---most importantly a lower direct bound of 3 yr on the photon lifetime, should the photon mass be at its conservative upper limit. In that case, the lifetime of microwave photons will be time-dilated by a factor order 10^(15).

description: *Winner of the 2018 International Writing Centers Association Best Article Award. Histories of writing program administration tacitly focus on predominantly-white institutions (PWIs). “’Raising Hell’: Literacy Instruction in Jim Crow America” is one study that fills a gap created by those larger narratives. In the process, it demonstrates that historically-black college and university (HBCU) writing program administrators faced unique exigencies during the Jim Crow era. And they responded in ways that were politically and technologically savvy: teaching their students literacies that they could mobilize to fight for political and economic justice in a nation that failed to treat them as full citizens. “Raising Hell” tells the remarkable story of the Hampton Institute (now Hampton University) Communications Center. Hampton’s Communications Center was founded in 1941 as part of a larger project to help African-American students to compete for wartime jobs. At the Center, Hampton students received classroom and individual instruction in writing, speech, drama, radio, and print journalism. The Institute’s president paired this pedagogical experiment with a national campaign for fair hiring that challenged the South’s economic status quo. This combination of emerging literacies and fair hiring catapulted the school into controversies that played out across the pages of national newspapers, magazines, and newsreels. It inspired civil rights leaders W.E.B. DuBois and Walter White to pen editorials in support of Hampton’s educational project, citing the Communications Center as evidence of its value. And it led to the resignation of Hampton’s president. While HBCUs are underrepresented in the academic press of the era, newspapers and magazines covered them intensively. This study argues for the potential of popular press-based research to invest disciplinary histories with a thick description of writing program administrators’ socio-political contexts. And it shows the potential that lies in recently-digitized African-American newspaper archives to repopulate the field’s history with some of its most innovative and socially-progressive pioneers.

description: As exemplified by El Niño, the tropical Pacific Ocean strongly influences regional climates and their variability worldwide. It also regulates the rate of global temperature rise in response to rising GHGs. The tropical Pacific Ocean response to rising GHGs impacts all of the world’s population. State-of-the-art climate models predict that rising GHGs reduce the west-to-east warm-to-cool sea surface temperature gradient across the equatorial Pacific5. In nature, however, the gradient has strengthened in recent decades as GHG concentrations have risen sharply. This stark discrepancy between models and observations has troubled the climate research community for two decades. Here, by returning to the fundamental dynamics and thermodynamics of the tropical ocean–atmosphere system, and avoiding sources of model bias, we show that a parsimonious formulation of tropical Pacific dynamics yields a response that is consistent with observations and attributable to rising GHGs. We use the same dynamics to show that the erroneous warming in state-of-the-art models is a consequence of the cold bias of their equatorial cold tongues. The failure of state-of-the-art models to capture the correct response introduces critical error into their projections of climate change in the many regions sensitive to tropical Pacific sea surface temperatures.

description: To determine the precise link between anatomical structure and function, brain studies primarily concentrate on the anatomical wiring of the brain and its topological properties. In this work, we investigate the weighted degree and connection length distributions of the KKI-113 and KKI-18 human connectomes, the fruit fly, and of the mouse retina. We found that the node strength (weighted degree) distribution behavior differs depending on the considered scale. On the global scale, the distributions are found to follow a power-law behavior, with a roughly universal exponent close to 3. However, this behavior breaks at the local scale as the node strength distributions of the KKI-18 follow a stretched exponential, and the fly and mouse retina follow the lognormal distribution, respectively which are indicative of underlying random multiplicative processes and underpins non-locality of learning in a brain close to the critical state. However, for the case of the KKI-113 and the H01 human (1mm$^3$) datasets, the local weighted degree distributions follow an exponentially truncated power-law, which may hint at the fact that the critical learning mechanism may have manifested at the node level too.

Anomalous magnetic moment of an electron near a dispersive surface

Year: 2013

description: Changes in the magnetic moment of an electron near a dielectric or conducting surface due to boundary-dependent radiative corrections are investigated. The electromagnetic field is quantized by normal mode expansion for a non-dispersive dielectric and an undamped plasma, but the electron is described by the Dirac equation without matter-field quantization. Perturbation theory in the Dirac equation leads to a general formula for the magnetic moment shift in terms of integrals over products of electromagnetic mode functions. In each of the models investigated contour integration techniques over a complex wave vector can be used to derive a general formula featuring just integrals over transverse electric and transverse magnetic reflection coefficients of the surface. Analysis of the magnetic moment shift for several classes of materials yields markedly different results from the previously considered simplistic 'perfect reflector' model, due to the inclusion of physically important features of the electromagnetic response of the surface such as evanescent field modes and dispersion in the material. For a general dispersive dielectric surface, the magnetic moment shift of a nearby electron can exceed the previous prediction of the perfect-reflector model by several orders of magnitude.

description: This paper is the first to investigate the costs of institution-wide reforms at community colleges. Drawing on data from 12 community colleges implementing comprehensive guided pathways reforms, the author uses the ingredients method to analyze the resources required to implement such reforms and examine their feasibility and affordability, as well as their value for students. For a typical college with 4,000 full-time equivalent students (FTEs) that implements guided pathways over four years, the total implementation cost beyond business-as-usual operations is estimated at $450 per student each year, or $7.1 million in total, which amounts to 12% of the college’s annual budget, or approximately 3% per year. Around one third of this cost is for enhanced student advisement. Extra investments in information technology are also significant. Ongoing operating costs, primarily for student advisement and student success courses, are around $350 per FTE each year. Cost estimates vary depending on how colleges implement guided pathways, but the results are robust to alternative input prices and college characteristics. There is also some evidence of economies of scale. To finance guided pathways, colleges relied mainly on resource reallocation and efficiency gains, extra public funding, and external grants and funds. Increases in tuition/fees were modest, temporary, or delayed until after implementation; increases of just under 1% per year would suffice to support guided pathways reforms. From the student perspective, guided pathways increases the affordability and value for money of community college. With enhanced advising, students take fewer unnecessary courses. Program mapping leads students to take the right courses both at the community college and at any transfer college. Improved advising help students access grants and in-kind services; they also assist with financial plans to pay for college. Overall, the savings these reforms allow for are likely to exceed the modest increase in tuition/fees from guided pathways. An accompanying practitioner guide describes the resourcing decisions colleges made to implement guided pathways.

description: The transverse broadening of an energetic jet passing through a non-Abelian plasma is believed to be described by the thermal expectation value of a light-cone Wilson loop. In this exploratory study, we measure the light-cone Wilson loop with classical lattice gauge theory simulations. We observe, as suggested by previous studies, that there are strong interactions already at short transverse distances, which may lead to more efficient jet quenching than in leading-order perturbation theory. We also verify that the asymptotics of the Wilson loop do not change qualitatively when crossing the light cone, which supports arguments in the literature that infrared contributions to jet quenching can be studied with dimensionally reduced simulations in the space-like domain. Finally we speculate on possibilities for full four-dimensional lattice studies of the same observable, perhaps by employing shifted boundary conditions in order to simulate ensembles boosted by an imaginary velocity.

Our calculus enjoys confluence without any restriction. Its type system enforces strong normalization of expressions and it is a sound and complete system for full implicational Classical Logic. We give a very simple denotational semantics which allows easy calculations of the interpretation of expressions.

description: In recent years, there has been a growing recognition that the traditional system of college mathematics remediation that relies on high-stakes placement tests and prerequisite, multilevel course sequences is associated with lowered chances of students completing developmental requirements and increased rates of student attrition. This recognition has led to nationwide reform efforts that strive to alter the structure and curricula of remedial math courses. However, these broad-based reforms have been insufficient in eliminating inequities in developmental placement and completion between students of color and other underserved students and their more advantaged peers. Informed by relevant research literature, this paper argues that the majority of reforms to developmental math education seek to remedy general barriers to student progress but are not typically designed to address equity gaps and, perhaps unsurprisingly, do little to reduce them. The authors examine issues of concern present in traditional developmental math education and how existing reforms—including assessment and placement reforms, acceleration reforms, contextualization reforms, and curricular and pedagogic reforms—aim to address these issues, noting if they are associated with reductions in equity gaps. The authors also explore the potential for targeted reforms in developmental math to more effectively address the factors that contribute to inequities in student outcomes, factors such as stereotype threat, math anxiety, instructor bias, and tracking. The paper concludes with recommendations for colleges: create and use developmental and college-level math curriculum and instruction that affirms students’ math ability and improves their confidence, engage in student-centered instructional practices that encourage conceptual understanding of math and give students a sense of ownership over their own learning, provide professional development to faculty to help identify and remediate instructor biases, develop policies and practices that prevent the tracking of underserved students into less rigorous math courses and/or developmental education, and, similarly, consider ways to increase access to STEM courses for Black and Latinx students.

description: In the United States, the prevailing high school mathematics course sequence begins with a year of Algebra I, followed by a year of geometry and a year of Algebra II. Educators and others have raised concerns about the extent to which this sequence, which prioritizes the mastery of algebra, is appropriate for the longer term education and career goals of students who do not intend to pursue STEM degrees in college. These concerns have impelled educators and policymakers to reexamine the prominence of algebra in high school mathematics curricula and to consider new approaches that provide students with more mathematics course options better aligned with their academic and career goals. This paper explores existing approaches to high school mathematics curricula as well as new developments in the field. The authors discuss a range of high school mathematics course sequences and look at some of the systemic challenges embedded within the traditional paradigm. They also examine federal and state changes to the provision of high school mathematics in the early 21st century, the influence of postsecondary institutions on high school math curricula, and innovative high school math reforms occurring in Ohio, California, Oregon, Texas, and Washington. The paper concludes with a discussion of how the Charles A. Dana Center’s new initiative, Launch Years, works to reimagine high school mathematics and its relationship to postsecondary education and careers.

description: This paper considers the representational role of music in theatre, and how music can help to communicate complex elements of ‘lived time’. I extract case studies from Jeremy O. Harris’ Slave Play (2019), a recent Broadway production which explores the impact in contemporary America of inherited trauma from slavery, by interrogating the sexual power imbalances within three interracial couples. Both characters exhibit musical hallucinations associated with their obsessive-compulsive disorder. I theorize how the musical examples emerge as an indirect emotional and temporal byproduct of the struggles facing two of the characters. I argue that their hallucinations ‘suspend’ lived time, and are an attempt to overcome “restriction, uncertainty, and blockage,” with regard to their intimate relationships (Sara Ahmed 2006, p.139). I consider much of the music in Slave Play to perform a metadiegetic function. The secondary narration, constructed by ‘queer time’, is represented through the two popular musical examples, Rihanna’s “Work” (2016) and Unknown Mortal Orchestra’s “Multi-Love.” Both songs are ridden with intertextual significance, and are integrated meaningfully into the temporality of the play through Harris’ autofictional approach to writing. Slave Play stands at the forefront of a budding genre of theatre, one which largely does away with traditional theatrical convention by blending the distinction between musical and traditional theatre. This requires a novel academic approach—drawing from both musical and traditional theatre scholarship, queer theory, and philosophies of time and music.

description: Oceanic uptake of anthropogenic CO2 emissions induced global seawater pH decrease by 0.1 since the Industrial Revolution by altering ocean chemistry with the reduction of carbonate ion concentrations and the saturation states of aragonite. Massive tropical corals are ideal palaeoceanographic archives providing high-resolution records of the most recent few hundred years and offer a valuable extension to instrumental measurements. The South Pacific Convergence Zone (SPCZ), the largest persistent precipitation band in the Southern Hemisphere with an associated salinity front modulated by large-scale ocean-atmospheric interactions (El Niño/Southern Oscillation, Interdecadal Pacific Oscillation) may influence regional seawater CO2 absorption and pH variability. Here we present coral-based paleoclimatic reconstructions from two Porites sp. corals of the Southwest Pacific region from Tonga and Rotuma. The corals are analyzed using a multi-proxy approach (δ18O, Sr/Ca, Li/Mg, U/Ca, Sr-U) to assess optimal sea surface temperature reconstruction. Preliminary δ18O results from both corals suggest similar freshening and/or warming of the surface water for the last 30 years of the 20th century (Tonga: -0.0038‰ δ18O per year; Rotuma: -0.0033‰ δ18O per year). Coral B/Ca and δ11B results for the reconstruction of carbonate chemistry changes and to establish the longer-term variability of seawater pH were completed. Tonga Porites sp. δ11B signature indicate a significant decreasing trend since 1779, with a pronounced depletion in δ11B since the 1950s of -0.0626 per year. Ultimately, this study will explore the regional-scale oceanic response to increasing pCO2 and temperature, as well as the influence of interannual and decadal-interdecadal climatic fluctuations.

description: This paper analyzes the life and work of Julius Eastman (1940–1990), namely his 1980 Northwestern Concert Series and Grammy-nominated Eight Songs for A Mad King (1973) alongside anti-black state violence in the United States as sites of black sonority made legible through and against, what Christina Sharpe calls, “the wake” of chattel slavery (2016). The mouth, stifled breath, and voice, I have argued, all persist through the reiterative scene of state-sanctioned violence against black and brown people. I am interested in the historicized phenomenology of sounds produced in radically different scenes of performance and murder. That is, the history of black and brown folx in America is, in part, produced out of, “[t]he ‘very dangerous evil’ of slavery and the ‘agonizing groans of suffering humanity’ [that] had been made music” (Saidiya Hartman 1997, 17). The paper departs from the scene of black sonority processed under duress to query: what are the effects of racialized aesthetic production, as evident in the Eastman’s musical groan or shriek that is eerily similar to the foreclosure of black breath, that emerge at the impasse between virtuosic sound and historicized dispossession? I offer an alternative reading of sound production by way of what Ashon T. Crawley who crafts a hermeneutics of the sound of blackness offers a consideration of black sound making “otherwise.” The breath of black and brown folx that persists in spite of antiblackness must flow into putatively apolitical disciplines like Musicology in an effort to render (il)legible life sonorous otherwise.

description: In this paper sequent calculi for the classical fragment (that is, the conjunction-disjunction-implication-negation fragment) of the nonsense logics B3, introduced by Bochvar, and H3, introduced by Halldén, are presented. These calculi are obtained by restricting in an appropriate way the application of the rules of a sequent calculus for classical propositional logic CPL. The nice symmetry between the provisos in the rules reveal the semantical relationship between these logics. The Soundness and Completeness theorems for both calculi are obtained, as well as the respective Cut elimination theorems.

description: In this essay, I examine the development of the ethno/musicologies’ (queer) theoretical borrowings from anthropology, sociology, and literary/cultural studies in order to historicize the contemporary queer moment both fields are experiencing and demonstrate the ways in which it might disorient the field. I trace the histories of this queering trend by beginning with early conceptualizations of the ethno/musicological projects, scientism, and quantitative methods. This is in relation to the anthropological method of ethnocartography in order to understand the historical difficulties in creating a queer qualitative field, as opposed to those based in hermeneutics. The first section places the problematics of this enumeration in dialogue with the ethno/musicologies’ tendencies towards nationalizing and globalizing narratives that often run contrary to a queer project. In working at this larger scale of social interaction, it is difficult to understand the intricacies of sexualities and their relation to local normativities—that is, the project of nation-building from the nineteenth through late twentieth centuries makes difficult discussions on genders and sexualities as they exist within ethnic, racial, dis/abled, or religious minority groups subsumed by the nation-state. While both national and global perspectives are useful in understanding mass media and politics, as well as in answering the cui bono question, they often lose sight of individuals and their complex negotiations of identity and place. This section draws on what one might consider the early queer ethnomusicological literature to illuminate this nationalizing tendency
Observability of dynamical tides in merging eccentric neutron star binaries

description: While dynamical tides only become relevant during the last couple of orbits for circular inspirals, orbital eccentricity can increase their impact during earlier phases of the inspiral by exciting tidal oscillations at each close encounter. We investigate the effect of dynamical tides on the orbital evolution of eccentric neutron star binaries using post-Newtonian numerical simulations and construct an analytic stochastic model that reproduces the numerical results. Our study reveals a strong dependence of dynamical tides on the pericenter distance, with the fractional energy transferred to dynamical tides over that dissipated in gravitational waves (GWs) exceeding $\sim1\%$ at separations $r_\mathrm{p}\lesssim50$ km for large eccentricities. We demonstrate that the effect of dynamical tides on orbital evolution can manifest as a phase shift in the GW signal. We show that the signal-to-noise ratio of the GW phase shift can reach the detectability threshold of $8$ with a single aLIGO detector at design densitivity for eccentric neutron star binaries at a distance of $40$ Mpc. This requires a pericenter distance of $r_\mathrm{p0}\lesssim68$ km ($r_\mathrm{p0}\lesssim76$ km) at binary formation with eccentricity close to $1$ for a reasonable tidal deformability and f-mode frequency of $500$ and $1.73$ kHz ($700$ and $1.61$ kHz), respectively. The observation of the phase shift will enable measuring the f-mode frequency of neutron stars independently from their tidal deformability, providing significant insights into neutron star seismology and the properties of the equation of state. We also explore the potential of distinguishing between equal-radius and twin-star binaries, which could provide an opportunity to reveal strong first-order phase transitions in the nuclear equation of state.

Mice Infected with Low-virulence Strains of Toxoplasma gondii Lose their Innate Aversion to Cat Urine, Even after Extensive Parasite Clearance

description: Toxoplasma gondii chronic infection in rodent secondary hosts has been reported to lead to a loss of innate, hard-wired fear toward cats, its primary host. However the generality of this response across T. gondii strains and the underlying mechanism for this pathogen mediated behavioral change remain unknown. To begin exploring these questions, we evaluated the effects of infection with two previously uninvestigated isolates from the three major North American clonal lineages of T. gondii, Type III and an attenuated strain of Type I. Using an hour-long open field activity assay optimized for this purpose, we measured mouse aversion toward predator and non-predator urines. We show that loss of innate aversion of cat urine is a general trait caused by infection with any of the three major clonal lineages of parasite. Surprisingly, we found that infection with the attenuated Type I parasite results in sustained loss of aversion at times post infection when neither parasite nor ongoing brain inflammation were detectable. This suggests that T. gondii-mediated interruption of mouse innate aversion toward cat urine may occur during early acute infection in a permanent manner, not requiring persistence of parasitecysts or continuing brain inflammation.

description: This article has its source in a larger research project on distorted guitar playing in rock music which focuses on distortion’s effect on playability and expressiveness, its psychological influences on chord perception, composition, and production, and on issues regarding genre aesthetics. While most work on rock music and guitar cultures has either studied recorded and transcribed music or the star’s personality, behavior, and medial staging, this empirical study mainly focuses on amateur and semi-professional musicians, but it also evaluates statements of professional guitarists of various prominence. It explores guitar players’ views and attitudes as well as their preferred equipment, based on the theoretically grounded assumption that musicians’ use of equipment is strongly connected with genre conventions.
A Reappraisal of the Relationship Between Benjamin Britten and Walter Greatorex

description: Walter Greatorex was Music Master at Gresham’s School from 1911 to 1936. Benjamin Britten was his pupil from 1928-1930 (aged 14-16). The received view is that Britten despised him as incompetent, unimaginative and reactionary. This view is based on Britten’s letters home from Gresham’s and an often repeated passage from Imogen Holst’s 1966 biography of Britten. This paper views these pieces of evidence in their wider context, and draws on new primary sources from Gresham’s School archives to question this opinion. It seeks to demonstrate that Greatorex was a musician and teacher of considerable gifts. Further, his commitment to including all members of the school community in music making might be seen as subliminally influential on Britten’s view of his own place in society and on his poly-technical works such as St Nicolas (1948), The Little Sweep (1949) and Noye’s Fludde (1958).
Analysis of an inclined thrust axis as applied to a ramjet propelled aircraft

description: The low values of lift-drag ratio attained by supersonic wing configurations provide the opportunity for the utilization of an inclined thrust axis. The exhaust jet of a ramjet propelled aircraft is inclined in order to use some of the jet force to supply additional lift. This has the effect of augmenting the lift by the relatively large sine component of the jet force whereas the thrust in the flight direction is reduced only by the smaller change in the cosine component.

It was found that this principle offers a substantial decrease in fuel consumption over that of a normal ramjet for probable values of lift-drag ratios above Mach number 1.5. Almost all of the possible decrease can be obtained with jet inclination angles of 15° or less.
