description: In a phase I clinical trial, we are interested in finding a dose mu that will produce toxicity at an acceptable probability level Gamma in the target population. We investigate various estimators of the target dose mu to be used with the up-and-down Biased Coin Design (BCD) introduced by Durham and Flournoy (1994). These estimators of mu are derived using isotonic regression, maximum likelihood, weighted least squares, and the simple empirical mean. The best of these estimators, based on the mean square error criterion, will be used to compare different stopping rules based on the fixed width confidence interval and the observed dose frequency. Given a vector of probability of toxicity at the different doses, we show how to derive the exact distribution of these (and many other) estimators. However, due to computational limitations, for modest samples (n > 15), the exact method becomes infeasible and bootstrap methods are used. Asymptotic results will be derived, when possible, assuming the probability of toxicity follows a logistic function. We derive the exact covariance between the number of subjects at dose x j and the number of toxicities at dose xk. We also approximate the covariance between logit( Pj) and logit(Pk), where Pi = P(toxicity|dose xi). Finally the "best" of these estimators with the "best" stopping rule in the BCD setting will be compared to the Continual Reassessment Method (CRM) in terms of expected sample size, the distribution of allocated doses and the distribution of the recommended dose.

Electrical and seismological structure of the martian mantle and the detectability of impact-generated anomalies

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: We derive synthetic electrical conductivity, seismic velocity, and density distributions from the results of martian mantle convection models affected by basin-forming meteorite impacts. The electrical conductivity features an intermediate minimum in the strongly depleted topmost mantle, sandwiched between higher conductivities in the lower crust and a smooth increase toward almost constant high values at depths greater than 400 km. The bulk sound speed increases mostly smoothly throughout the mantle, with only one marked change at the appearance of $β$-olivine near 1100 km depth. An assessment of the detectability of the subsurface traces of an impact suggests that its signature would be visible in both observables at least if efficient melt extraction from the shock-molten target occurs, but it will not always be particularly conspicuous even for large basins; observations with extensive spatial and temporal coverage would improve their detectability. Electromagnetic sounding may offer another possibility to investigate the properties of the mantle, especially in regions of impact structures. In comparison with seismology and gravimetry, its application to the martian interior has received little consideration so far. Of particular interest is its potential for constraining the water content of the mantle. By comparing electromagnetic sounding data of an impact structure with model predictions, it might also be possible to answer the open question of the efficiency of extraction of impact-generated melt.

Military medical aid to civilians: Altruism or *policy?

description: Medical services have long been an integral part of the military and warfare. The primary mission of military medical services is to preserve the military's fighting strength. Civilians, however, are also caught up in wars. This dissertation discusses the care of civilians by military medical services, and the use of medical services as a tool to advance war aims. Following a discussion of the role of medical care of civilians in previous wars, this thesis focuses upon U.S. involvement in the Vietnam War. Archival sources serve to delineate the various programs, both in hospitals and in the field. The development and transformations of the programs and their relationship to the changing war effort and war aims forms the body of the work. This paper evaluates the quality of medical care delivered to the Vietnamese people, and discusses the use of medical care as an instrument of policy to advance the war effort. The quality of medical care delivered to the Vietnamese people varied greatly. Those receiving care in hospitals with American medical personnel received excellent care. Those seen in village and hamlet settings by the medical sections of line units frequently did not. Follow-up or long-term care was absent. Individuals may have benefited from the care they received, but there is no evidence of a improvement in the Vietnamese health care system. Did the use of medical care aid the war effort? Certainly the "hearts and minds" of those who benefited directly from military medical care may have been won over to the U.S., but there is no evidence that the Republic of Vietnam benefited. Conflicting lines of authority and confusion over medical assets offered to civilians reflected the larger ambiguities of the American war effort. Medical care can be instrumental in winning popular support under certain conditions: an absence of satisfactory medical care, a population whose support is sought by both sides of the conflict, and a limited war or insurrection. In Vietnam the first two of these existed, but the limited war phase of the conflict had passed before the major United States troop buildup.
Distance Matters For Improving Performance Estimation Under Covariate Shift

description: Performance estimation under covariate shift is a crucial component of safe AI model deployment, especially for sensitive use-cases. Recently, several solutions were proposed to tackle this problem, most leveraging model predictions or softmax confidence to derive accuracy estimates. However, under dataset shifts, confidence scores may become ill-calibrated if samples are too far from the training distribution. In this work, we show that taking into account distances of test samples to their expected training distribution can significantly improve performance estimation under covariate shift. Precisely, we introduce a "distance-check" to flag samples that lie too far from the expected distribution, to avoid relying on their untrustworthy model outputs in the accuracy estimation step. We demonstrate the effectiveness of this method on 13 image classification tasks, across a wide-range of natural and synthetic distribution shifts and hundreds of models, with a median relative MAE improvement of 27% over the best baseline across all tasks, and SOTA performance on 10 out of 13 tasks.

title: An investigation of sulphur in carbonaceous and enstatite chondrites by stepped combustion
Creators: name: Burgess, Raymond
Publisher: name: The Open University
Year: 1987

description: A stepped combustion technique has been developed to resolve the different sulphur-bearing components of meteorites. The technique has been applied to studies of carbonaceous and enstatite chondrites. Stepped combustion of C1 and C2 carbonaceous chondrites provides evidence for the presence of secondary sulphur minerals. Evidence for six different sulphur components has been found (elemental and organic sulphur, sulphides, FESON and sulphates). Most of the sulphur in C1 and C2 chondrites both contain the same sulphur components suggesting that hydrothermal alteration may have evolved along a common pathway. Changes in sulphur isotopic composition associated with alteration have led to an enrichment of 34S in elemental sulphur and sulphates compared to the starting sulphide material. Most of the sulphur in C3, C4 and C5/6 chondrites is present as sulphide, but stepped combustion has demonstrated that there is also a component of preterrestrial oxidised sulphur in these materials. Chemical evidence suggests that oxidised sulphur may occur as FESON or anhydrite. This finding indicates that C3 and C4 chondrites have undergone a small amount of hydrous alteration on the meteorite parent body and this provides an important evolutionary link with C1 and C2 meteorites. The stepped combustion method has been used as a means of assessing the relative abundances of the two main sulphides (troilite and oldhamite) in enstatite chondrites and aubrites. It was found that troilite and oldhamite abundances both decrease systematically with petrologic grade. The variability of these two minerals provides constraints on models envisaged for the evolution of the enstatite chrondrite parent body. Enstatite chondrites have whole-rock delta34S values of close to 0%, whereas aubrites are depleted in 32S by up to 2%.

description: This paper investigates asymptotic properties of multifractal products of random fields and multidimensional multifractal measures. The obtained limit theorems provide sufficient conditions for the convergence of cumulative fields in the spaces Lq. New results on the rate of convergence of cumulative fields are presented. Simple unified conditions for the limit theorems and the calculation of the Rényi function are given. They are less restrictive than those in the known one-dimensional results. The developed methodology is also applied to multidimensional multifractal measures. Finally, an application to a new class of examples of geometric φ-sub-Gaussian random fields is presented. In this case, the general assumptions have a simple form and can be expressed in terms of covariance functions only.

description: We report an ARPES investigation of the circular dichroism in the first Brillouin zone (BZ) of under- and overdoped Pb-Bi2212 samples. We show that the dichroism has opposite signs for bonding and antibonding components of the bilayer-split CuO-band and is antisymmetric with respect to reflections in both mirror planes parallel to the c-axis. Using this property of the energy and momentum intensity distributions we prove the existence of the bilayer splitting in the normal state of the underdoped compound and compare its value with the splitting in overdoped sample. In agreement with previous studies the magnitude of the interlayer coupling does not depend significantly on doping. We also discuss possible origins of the observed dichroism.

description: This urban school case study was designed to document the experiences of teachers, Instructional Support Teachers (ISTs), and their administrators from an elementary school engaged in the Baltimore Urban Systemic Initiative (BUSI). Subjects of analysis within the representative urban school consisted of three teachers, the IST, and principal. The representative school was nominated by an Advisory Council, which consisted of the Mathematics: Application and Reasoning Skills (MARS) Project external evaluator, Project Director, the Mathematics Coordinator of Baltimore City Public Schools (BCPS), and the researcher. The representative elementary school was nominated by the Advisory Council from among 52 BCPS participating in the MARS Project based on the following criterion: (1) the school is attempting to implement NCTM Standards -based curriculum and instruction; (2) there exists at least one teacher in the school who believes the MARS Project has benefited the school, the students and their own teaching; and (3) there exists at least one teacher in the school who believes that the MARS Project has not benefited the school, the students and their own teaching. Inductive analysis and methods triangulation were used to converge and compare: the researcher's analysis and evaluation of the BUSI retrospective and mass-descriptive surveys, the BUSI Annual Reports from 1996--1998, observations of the teacher enhancement summer workshop, focus groups with the administrative unit, semi-structured interviews with the individual members of the administrative unit, classroom observations using the Horizon Research observation protocol and the researcher's field notes. Findings from this research revealed that the greatest concerns among participating teachers about implementing the Standards-based curriculum and instruction in the MARS Project were: being confident in their ability to teach the math content in a way consistent with the NCTM Standards and MARS Project framework, having enough planning time to prepare, being able to cover the entire (BCPS) curriculum, differentiating instruction for the students who need extra time, struggling with the tendency to return to old teaching habits, having enough time with the IST, keeping the students actively stimulated and engaged in their learning, and managing the classroom, using a new approach to teaching and learning.

description: We study the localization volumes $V$ (participation ratio) of electronic wave functions in the 2d-Anderson model with diagonal disorder. Using a renormalization procedure, we show that at the band edges, i.e. for energies $E\approx \pm 4$, $V$ is inversely proportional to the variance $\var$ of the site potentials. Using scaling arguments, we show that in the neighborhood of $E=\pm 4$, $V$ scales as $V=\var^{-1}g((4-\ve E\ve)/\var)$ with the scaling function $g(x)$. Numerical simulations confirm this scaling ansatz.

description: We designed a machine learning algorithm that identifies patterns between ESG profiles and financial performances for companies in a large investment universe. The algorithm consists of regularly updated sets of rules that map regions into the high-dimensional space of ESG features to excess return predictions. The final aggregated predictions are transformed into scores which allow us to design simple strategies that screen the investment universe for stocks with positive scores. By linking the ESG features with financial performances in a non-linear way, our strategy based upon our machine learning algorithm turns out to be an efficient stock picking tool, which outperforms classic strategies that screen stocks according to their ESG ratings, as the popular best-in-class approach. Our paper brings new ideas in the growing field of financial literature that investigates the links between ESG behavior and the economy. We show indeed that there is clearly some form of alpha in the ESG profile of a company, but that this alpha can be accessed only with powerful, non-linear techniques such as machine learning.
A natural framework for bi-large neutrino mixing

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: In this talk I describe a natural framework for bi-large neutrino mixing within the context of two models -- 1) a simple generalization of the MSSM and 2) an SO(10) model. Our starting point is the Frampton, Glashow, Yanagida [FGY] neutrino mass ansatz which can easily accomodate bi-large neutrino mixing. The main point of FGY, however, is to obtain a theory of neutrino masses with only one possible CP violating angle. They argue that the sign of the baryon asymmetry of the universe (assuming leptogenesis) is then correlated with CP asymmetries possibly observable in accelerator experiments. Unfortunately, there is a fly in the ointment. It was later shown by Raidal and Strumia [RS] that there is a sign ambiguity which frustrates the above correlation. We note that the Raidal-Strumia ambiguity is resolved in our models.

description: Since the 1960s, more than a million Buddhists have immigrated from Asia to the United States, joining descendants of Buddhists who came from China and Japan as early as 1840. The impact of these "ethnic" Buddhists on American religion and culture has been overshadowed in the media and scholarly research by the growing numbers of Americans who, in recent decades, have converted to Buddhism or sympathize with its teachings. These two groups of Buddhists, converts and immigrants, developed along separate historical and geographic trajectories, and it is only at the end of the twentieth century that all the traditions of Buddhism have come together in one place. In terms of their religious beliefs and practices, immigrants and converts are often considered so fundamentally different that researchers speak of a gap dividing the "two Buddhisms."; At the Washington Buddhist Vihara, a Theravada temple in Washington, D.C., Sinhalese immigrants participate together with American converts in classes, worship services, ceremonies and informal gatherings. This mixed congregation challenges the assumption that ethnic and convert Buddhists constitute naturally separate, homogenous communities; in fact, the Vihara functions as a point of contact through which relations of community and difference are negotiated. This study, based on fieldwork at the Vihara, problematizes the notion that people, place, and culture are inherently linked, and shows that differences in practice and perspective are constructed and maintained through ongoing interaction within an existing hierarchy of relations, rather than being the natural outcome of historical and geographic separateness. Participants at the Vihara express a variety of interests, constraints, and abilities, as evidenced by the multiple and highly contextual ways they define and use this place---how they practice, plan and organize events, modify their surroundings, interpret one another's actions, contest opposing views, and engage with the rapidly changing world around them. Through these kinds of "placemaking" activities, participants negotiate cultural meanings, relationships, and values on both local and global levels. As this diverse group of Buddhists comes together in the pluralist context of the United States, they may also be producing a place in which difference acquires new meaning.

A general disequilibrium benefit/cost analysis of elder care facilities in Mexico for United States citizens
Creators: name: Hunt, Susan B.
Publisher: name: American University
Year: 2023

description: Benefit/cost analysis is used to analyze a Mexican elder care project designed to serve U.S. citizens relocating to Mexico for care. The Mexican elder-care provider will be organized as a Mondragon-type worker-owned-and-managed cooperative. The worker-owners will be Mexican citizens drawn from the lower rungs of the socio-economic ladder. The U.S. citizens they will serve are elders who are unable to pay for quality elder-care in the United States. Beginning in 2008, the share of the U.S. population aged 65 and older is projected to increase rapidly as the baby-boom generation retires, and is expected to remain far above current levels indefinitely unless birth rates rise significantly. The demand for long-term care is expected to increase proportionately. Because the services required by aging seniors are relatively labor-intensive, and because Mexican labor is cheap relative to U.S. labor, encouraging more seniors to relocate to Mexico might make an important contribution to health care cost containment in the U.S. The General Disequilibrium methodology developed by Professor Daniel Schydlowsky of American University is employed to estimate shadow prices for Mexico's labor, capital and foreign exchange markets, and to perform the benefit/cost analysis. An extensive profile of the Mexican labor market supports a shadow price of labor that is zero or even negative. The project is found to be beneficial to Mexico under several sets of assumptions.

The realisation of an engineered quantum system, where the predicted phase transition shall occur, is also presented. We study a suitable generalization of the sine-Gordon model in four dimensions and the renormalization group flow equation of its couplings, showing that the critical value of the frequency is the square of the corresponding value in $2D$. The value of the anomalous dimension at the critical point is determined ($η=1/32$) and a conjecture for the universal jump of the superfluid stiffness ($4/π^2$) presented.

description: Benefit/cost analysis is used to analyze a Mexican elder care project designed to serve U.S. citizens relocating to Mexico for care. The Mexican elder-care provider will be organized as a Mondragon-type worker-owned-and-managed cooperative. The worker-owners will be Mexican citizens drawn from the lower rungs of the socio-economic ladder. The U.S. citizens they will serve are elders who are unable to pay for quality elder-care in the United States. Beginning in 2008, the share of the U.S. population aged 65 and older is projected to increase rapidly as the baby-boom generation retires, and is expected to remain far above current levels indefinitely unless birth rates rise significantly. The demand for long-term care is expected to increase proportionately. Because the services required by aging seniors are relatively labor-intensive, and because Mexican labor is cheap relative to U.S. labor, encouraging more seniors to relocate to Mexico might make an important contribution to health care cost containment in the U.S. The General Disequilibrium methodology developed by Professor Daniel Schydlowsky of American University is employed to estimate shadow prices for Mexico's labor, capital and foreign exchange markets, and to perform the benefit/cost analysis. An extensive profile of the Mexican labor market supports a shadow price of labor that is zero or even negative. The project is found to be beneficial to Mexico under several sets of assumptions.

description: Many real-world networks have properties of small-world networks, with clustered local neighborhoods and low average-shortest path (ASP). They may also show a scale-free degree distribution, which can be generated by growth and preferential attachment to highly connected nodes, or hubs. However, many real-world networks consist of multiple, inter-connected clusters not normally seen in systems grown by preferential attachment, and there also exist real-world networks with a scale-free degree distribution that do not contain highly connected hubs. We describe spatial growth mechanisms, not using preferential attachment, that address both aspects.

Lagrangian representation for fermionic linear optics

description: Notions of a Gaussian state and a Gaussian linear map are generalized to the case of anticommuting (Grassmann) variables. Conditions under which a Gaussian map is trace preserving and (or) completely positive are formulated. For any Gaussian map an explicit formula relating correlation matrices of input and output states is presented. This formalism allows to develop the Lagrangian representation for fermionic linear optics (FLO). It covers both unitary operations and the single-mode projectors associated with FLO measurements. Using the Lagrangian representation we reduce a classical simulation of FLO to a computation of Gaussian integrals over Grassmann variables. Explicit formulas describing evolution of a quantum state under FLO operations are put forward.

title: An investigation of the potential of anaerobically digested piggery waste for use in food production, with particular reference to tomato and fish production.
Creators: name: Watson, Nicholas R
Publisher: name: The Open University

description: The purpose of this study is to investigate the potential of animal waste for use in food production, by employing anaerobically digested piggery waste as a nutrient source for tomatoes and fish. The problem has been configured in terms of a "Bioplex" (integrated agriculture) system, and as such has been tackled by employing a bastardised systems methodology, which seeks to recognise the relationships between the resource to be used, and the food production system itself. This assumption underlies the experimental work carried out in the thesis. Initial experimentation comprised studies on the use of the piggery effluent in its raw form as a medium for the hydroponic production of tomatoes by nutrient film technique, and as a conventional fertiliser. These trials, and a study of the physical and chemical characteristics of the piggery waste indicated that in order to maximise the food production potential of the effluent, it should be viewed as a composite of three different fractions, each of which may be most usefully employed in a specific food production system. The bulk of the thesis is concerned with the extraction of two distinct fractions of the effluent; the protein rich suspended solids, and the aqueous phase, by means of an oxidation technique. The main criterion used to describe the success of the separation process is the application of the two products to food production operations, rather than the efficiency of the separation per se. To this end, the clarified liquid, and the separated solids were used as the basis of a nutrient solution for the hydroponic production of tomatoes, and a substitute protein source in the diet of common carp, respectively. The separation technique passed through two design iterations before products suitable as nutrient sources were generated. As the trials on fish and tomatoes were closely linked to the separation technique, this work occupies the main body of the thesis, and the initial feasibility experimentation is presented in the form of appendices.

description: We show that in single scalar field models of the dark energy with equations of state satisfying $w \equiv p / ρ< -1$, the effective Lagrangian for fluctuations about the homogeneous background has a wrong sign spatial kinetic term. In most cases, spatial gradients are ruled out by microwave background observations. The sign of $w+1$ is not connected to the sign of the time derivative kinetic term in the effective Lagrangian.

description: We study self-organized (s-) and driven (d-) synchronization in coupled map networks for some simple networks, namely two and three node networks and their natural generalization to globally coupled and complete bipartite networks. We use both linear stability analysis and Lyapunov function approach for this study and determine stability conditions for synchronization. We see that most of the features of coupled dynamics of small networks with two or three nodes, are carried over to the larger networks of the same type. The phase diagrams for the networks studied here have features very similar to the different kinds of networks studied in Ref. \cite{sarika-REA2}. The analysis of the dynamics of the difference variable corresponding to any two nodes shows that when the two nodes are in driven synchronization, all the coupling terms cancel out whereas when they are in self-organized synchronization, the direct coupling term between the two nodes adds an extra decay term while the other couplings cancel out.

description: We study the final state problem for the nonlinear Schrödinger equation with a critical long-range nonlinearity and a long-range linear potential. Given a prescribed asymptotic profile which is different from the free evolution, we construct a unique global solution scattering to the profile. In particular, the existence of the modified wave operators is obtained for sufficiently localized small scattering data. The class of potential includes a repulsive long-range potential with a short-range perturbation, especially the positive Coulomb potential in two and three space dimensions. The asymptotic profile is constructed by combining Yafaev's type linear modifier [38] associated with the long-range part of the potential and the nonlinear modifier introduced by Ozawa [29]. Finally, we also show that one can replace Yafaev's type modifier by Dollard's type modifier under a slightly stronger decay assumption on the long-range potential. This is the first positive result on the modified scattering for the nonlinear Schrödinger equation in the case when both of the nonlinear term and the linear potential are of long-range type.
