description: We propose a scheme for the quantum non-demolition (QND) measurement of Fock states of a nanomechanical resonator via feedback control of a coupled circuit QED system. A Cooper pair box (CPB) is coupled to both the nanoresonator and microwave cavity. The CPB is read-out via homodyne detection on the cavity and feedback control is used to effect a non-dissipative measurement of the CPB. This realizes an indirect QND measurement of the nanoresonator via a second-order coupling of the CPB to the nanoresonator number operator. The phonon number of the Fock state may be determined by integrating the stochastic master equation derived, or by processing of the measurement signal.

description: This paper develops a testing procedure to simultaneously check (i) the independence between the error and the regressor(s), and (ii) the parametric specification in nonlinear regression models. This procedure generalizes the existing work of Sen and Sen [“Testing Independence and Goodness-of-fit in Linear Models,” Biometrika, 101, 927–942.] to a regression setting that allows any smooth parametric form of the regression function. We establish asymptotic theory for the test procedure under both conditional homoscedastic error and heteroscedastic error. The derived tests are easily implementable, asymptotically normal, and consistent against a large class of fixed alternatives. Besides, the local power performance is investigated. To calibrate the finite sample distribution of the test statistics, a smooth bootstrap procedure is proposed and found work well in simulation studies. Finally, two real data examples are analyzed to illustrate the practical merit of our proposed tests.

description: The previous proposal (by two of us) of chain inflation with the QCD axion is shown to fail. The proposal involved a series of fast tunneling events, yet here it is shown that tunneling is too slow. We calculate the bubble nucleation rates for phase transitions in the thick wall limit, approximating the barrier by a triangle. A similar problem arises in realization of chain inflation in the string landscape that uses series of minima along the monodromy staircase around the conifold point. The basic problem is that the minima of the potential are too far apart to allow rapid enough tunneling in these two models. We entertain the possibility of overcoming this problem by modifying the gravity sector to a Brans-Dicke theory. However, one would need extremely small values for the Brans-Dicke parameter. Many successful alternatives exist, including other "axions" (with mass scales not set by QCD) or potentials with comparable heights and widths that do not suffer from the problem of slow tunneling and provide successful candidates for chain inflation.

description: We first study some properties of images of commuting differential operators of polynomial algebras of order one with constant leading coefficients. We then propose what we call the image conjecture on these differential operators and show that the Jacobian conjecture [BCW], [E], [Bo] (hence also the Dixmier conjecture [D]) and the vanishing conjecture [Z3] of differential operators with constant coefficients are actually equivalent to certain special cases of the image conjecture. A connection of the image conjecture, and hence also the Jacobian conjecture, with multidimensional Laplace transformations of polynomials is also discussed.

description: This is the second part of a project concerning variation of stability and chamber structure for ADHM invariants of curves. Wallcrossing formulas for such invariants are derived using the theory of stack function Ringel-Hall algebras constructed by Joyce and the theory of generalized Donaldson-Thomas invariants of Joyce and Song. Some applications are presented, including strong rationality for local stable pair invariants of higher genus curves and comparison with wallcrossing formulas of Kontsevich and Soibelman, and the halo formula of Denef and Moore.

Reliability of acid-base variables of arterial blood using the astrup micro-equipment
Creators: name: Stevenson, Christopher Leonard
Publisher: name: University of British Columbia
Year: 2011

description: The test - retest reliability coefficients of the values of measurements made on the pH, the Pco₂, the standard bicarbonate, the base excess, and the buffer base, of arterial whole blood were estimated for a group of 30 male subjects with the use of the Astrup Micro-equipment, the Siggaard-Andersen revised Nomogram, and a testing program on three successive mornings. Reliability coefficients were estimated for these parameters in both the resting and the post-exercise conditions, and the intra-indivldual and the inter-individual variances were estimated for each reliability coefficient. It was found that the standard bicarbonate and the base excess had the more reliable values, and that the pH and PC0₂ had less reliable values. It was shown that the values of measurements of pH, standard bicarbonate and base excess were significantly different on Day 1 from those values on Days 2 and 3. This effect was attributed to apprehension towards the testing experience and to the strangeness of the testing environment. The measurement errors of the Astrup Micro-equipment and the Siggaard-Andersen revised Nomogram were estimated for the individual parameters. It was found that the buffer base was the only parameter in which the pH meter measurement error variance was large enough to have a decided effect upon the value of the reliability coefficient. The Nomogram measurement error variances were so small that they could be considered negligible. The temporal measurement error of the collection of blood - the error inherent in the time difference between the collection of successive tubes of blood - was investigated for the pH parameter. This temporal measurement error was shown to be practically negligible although statistically significant in the resting condition, but was shown to have both practical importance and statistical significance in the post-exercise condition.

description: GRB 090426 is a short duration burst detected by Swift ($T_{90}\sim 1.28$ s in the observer frame, and $T_{90}\sim 0.33$ s in the burst frame at $z=2.609$). Its host galaxy properties and some $γ$-ray related correlations are analogous to those seen in long duration GRBs, which are believed to be of a massive-star origin (so-called Type II GRBs). We present the results of its early optical observations with the 0.8-m TNT telescope at Xinglong observatory, and the 1-m LOAO telescope at Mt. Lemmon Optical Astronomy Observatory in Arizona. Our well-sampled optical afterglow lightcurve covers from $\sim 90$ seconds to $\sim 10^4$ seconds post the GRB trigger. It shows two shallow decay episodes that are likely due to energy injection, which end at $\sim 230$ seconds and $\sim 7100$ seconds, respectively. The decay slopes post the injection phases are consistent with each other ($α\simeq 1.22$). The X-ray afterglow lightcurve appears to trace the optical, although the second energy injection phase was missed due to visibility constraints introduced by the {\em Swift} orbit. The X-ray spectral index is $β_X\sim 1.0$ without temporal evolution. Its decay slope is consistent with the prediction of the forward shock model. Both X-ray and optical emission is consistent with being in the same spectral regime above the cooling frequency ($ν_c$). The fact that $ν_c$ is below the optical band from the very early epoch of the observation provides a constraint on the burst environment, which is similar to that seen in classical long duration GRBs. We therefore suggest that death of a massive star is the possible progenitor of this short burst.

description: Motivated by recent observations from Pamela, Fermi and H.E.S.S., we consider dark matter decays in the framework of supersymmetric SU(5) grand unification theories. An SU(5) singlet S is assumed to be the main component of dark matters, which decays into visible particles through dimension six operators suppressed by the grand unification scale. Under certain conditions, S decays dominantly into a pair of sleptons with universal coupling for all generations. Subsequently, electrons and positrons are produced from cascade decays of these sleptons. These cascade decay chains smooth the electron/positron spectrum, which permit naturally a good fit to the Fermi LAT data. The observed positron fraction upturn by PAMELA can be reproduced simultaneously. We have also calculated diffuse gamma-ray spectra due to the electron/positron excesses and compared them with the preliminary Fermi LAT data from 0.1 GeV to 10 GeV in the region 0

description: Using first-principles calculations, we have systematically studied the quantum size effects of ultrathin Pb(111) films on the adsorption energies and diffusion energy barriers of oxygen atoms. For the on-surface adsorption of oxygen atoms at different coverages, all the adsorption energies are found to show bilayer oscillation behaviors. It is also found that the work function of Pb(111) films still keeps the bilayer-oscillation behavior after the adsorption of oxygen atoms, with the values being enlarged by 2.10 to 2.62 eV. For the diffusion and penetration of the adsorbed oxygen atoms, it is found that the most energetically favored paths are the same on different Pb(111) films. And because of the modulation of quantum size effects, the corresponding energy barriers are all oscillating with a bilayer period on different Pb(111) films. Our studies indicate that the quantum size effect in ultrathin metal films can modulate a lot of processes during surface oxidation.

description: The age problem in the $Λ$CDM model is re-examined. We define the elapsed time $T$ of an object is its age plus the age of the Universe when it was born. Therefore in any cosmology, $T$ must be smaller than the age of the Universe. For the old quasar APM 08279+5255 at $z=3.91$, previous studies have determined the best-fit value of $T$, 1 $σ$ lower limit and the lowest limit to $T$ are 2.3, 2.0 and 1.7 Gyr, respectively. Constrained from SNIa$+R+A+d$, SNIa$+R+A+d+H(z)$, and WMAP5+2dF+SNLS+HST+BBN, the $Λ$CDM model can only accommodate $T(z=3.91)=1.7$ Gyr at 1 $σ$ deviation. Constrained from WMAP5 results only, the $Λ$CDM model can only accommodate $T(z=3.91)=1.7$ Gyr at 2 $σ$ deviation. In all these cases, we found that $Λ$CDM model accommodates the total age (14 Gyr for $z=0$) of the Universe estimated from old globular clusters, but cannot accommodate statistically the 1 $σ$ lower limit to the best-fit age of APM~08279+5255 at $z=3.91$. These results imply that the $Λ$CDM model may suffer from an age problem.

description: The study of J/ψ photoproduction at low energies has consequences for the understanding of multiple aspects of nonperturbative QCD, ranging from mechanical properties of the proton to the binding inside nuclei and the existence of hidden-charm pentaquarks. Factorization of the photon-c¯c and nucleon dynamics or vector meson dominance are often invoked to justify these studies. Alternatively, open-charm intermediate states have been proposed as the dominant mechanism underlying J/ψ photoproduction. As the latter violates this factorization, it is important to estimate the relevance of such contributions. We analyze the latest differential and integrated photoproduction cross sections from the GlueX and J/ψ−007 experiments. We show that the data can be adequately described by a small number of partial waves, which we parametrize with generic models enforcing low-energy unitarity. The results suggest a non-negligible contribution from open-charm intermediate states. Furthermore, most of the models present an elastic scattering length incompatible with previous extractions based on vector meson dominance and thus call into question its applicability to heavy mesons. Our results indicate a wide array of physics possibilities that are compatible with present data and need to be disentangled.
The women's intramural program at the University of British Columbia; an evaluation
Creators: name: Maclean, Alice Carol
Publisher: name: University of British Columbia
Year: 2011

description: The women’s intramural program at the University of British Columbia is comprised of two divisions; the university section and the physical education section. Physical education major students generally compete in the physical education section. The university section is composed of clubs, sororities, residences and faculties. In team activities of the university section, one physical education major student may compete for each team. In individual or dual activities of the university section, physical education students may not participate. The purpose of this thesis was to examine and assess the program of intramurals for women at the University of British Columbia. The writer made no attempt to generalize about the intramural programs at other universities. The interview and questionnaire methods of gathering data were used. Five student groups; the organization manager, the student executive, the student participants, the non-participating students, and the physical education major students were contacted. As well as this, three faculty members; the present intramural administrator, a past intramural administrator and the Director of the School of Physical Education and Recreation were interviewed. Visiting students and coaches were contacted to determine how intramural programs functioned at their respective universities. The participation statistics were checked to determine the actual number of participants and the number of games played during the fall term. The data was then compiled to indicate common trends. This was not meant to be a statistical study as it was felt that the ideas of those involved were more important than just the number of participants. It was found that the total intramural program is functioning slightly better than the students and faculty estimated when they were interviewed. An increase in publicity might, however, enhance the program and increase participation. It was agreed that a shift in emphasis in the physical education section might benefit the physical education major students. The philosophy and administration closely parallel those discussed in the review of literature and recommended by the Canadian Association for Health, Physical Education and Recreation, although there were some expected differences due to the unique situation at the University of British Columbia. While the intramural program is functioning relatively well, activities should not be allowed to be repeated without close scrutiny each year. There is still room for improvement.

description: The $\barν_{e}-e^{-}$ elastic scattering cross-section was measured with a CsI(Tl) scintillating crystal array having a total mass of 187kg. The detector was exposed to an average reactor $\barν_{e}$ flux of $\rm{6.4\times 10^{12} ~ cm^{-2}s^{-1}}$ at the Kuo-Sheng Nuclear Power Station. The experimental design, conceptual merits, detector hardware, data analysis and background understanding of the experiment are presented. Using 29882/7369 kg-days of Reactor ON/OFF data, the Standard Model(SM) electroweak interaction was probed at the squared 4-momentum transfer range of $\rm{Q^2 \sim 3 \times 10^{-6} ~ GeV^2}$. The ratio of experimental to SM cross-sections of $ ξ=[ 1.08 \pm 0.21(stat)\pm 0.16(sys)] $ was measured. Constraints on the electroweak parameters $(g_V , g_A)$ were placed, corresponding to a weak mixing angle measurement of $ \s2tw = 0.251 \pm 0.031({\it stat}) \pm 0.024({\it sys}) $. Destructive interference in the SM $\nuebar -$e process was verified. Bounds on anomalous neutrino electromagnetic properties were placed: neutrino magnetic moment at $μ_{\nuebar}< 2.2 \times 10^{-10} μ_{\rm B}$ and the neutrino charge radius at $-2.1 \times 10^{-32} ~{\rm cm^{2}} < \nuchrad < 3.3 \times 10^{-32} ~{\rm cm^{2}}$, both at 90% confidence level.

description: Mordechai Zalkin's work, published by Brill in 2016, is the English version of his book published in 2008 in Hebrew under the title From 'Heder' to School: The Modernisation Process in 19th Century East European Jewish Education. The book is a relatively short study of the ways in which the Jewish Enlightenment (Haskalah) and its proponents (maskilim) attempted to modernise the education of Eastern European Jews (here limited geographically to the territories of Russia, particularly the Pale of Settlement). As Zalkin argues, the subject of education has usually remained on the margins of wider studies of Haskalah. His work offers a unique insight into the "formulation of maskilic educational thinking" (p. 1). Although the author is fully aware of all major debates taking place among the maskilim, he devotes only one section of the book (chapter 5) to the practical implementation of these ideas. Because of its brevity (the book is 192 pages long, with only about 160 pages of actual content), Modernizing Jewish Education in Nineteenth Century Europe requires a very good knowledge of the nuanced history of Jewish Enlightenment, since Zalkin does not even attempt to introduce neither historical nor ideological context, in which all the theoretical debates on the subject of Jewish education took place

description: The out-of-equilibrium mean-field dynamics of a model for wave-particle interaction is investigated. Such a model can be regarded as a general formulation for all those applications where the complex interplay between particles and fields is known to be central, e.g., electrostatic instabilities in plasma physics, particle acceleration and free-electron lasers (FELs). The latter case is here assumed as a paradigmatic example. A transition separating different macroscopic regimes is numerically identified and interpreted by making use of the so-called violent relaxation theory. In the context of free-electron lasers, such a theory is showed to be effective in predicting the saturated regime for energies below the transition. The transition is explained as a dynamical switch between two metastable regimes, and is related to the properties of a stationary point of an entropic functional.

description: We investigate the dissociation of O2 on Pb(111) surface using first-principles calculations. It is found that in a practical high-vacuum environment, the adsorption of molecular O2 takes place on clean Pb surfaces only at low temperatures such as 100 K, but the O2 easily desorbs at (elevated) room temperatures. It is further found that the Pb adatoms enhance the molecular adsorption and activate the adsorbed O2 to dissociate during subsequent room-temperature annealing. Our theory explains the observation of a two-step oxidation process on the Pb surfaces by the unique role of Pb adatoms.

description: Black holes in equilibrium can be defined locally in terms of the so-called isolated horizon boundary condition given on a null surface representing the event horizon. We show that this boundary condition can be treated in a manifestly SU(2) invariant manner. Upon quantization, state counting is expressed in terms of the dimension of Chern-Simons Hilbert spaces on a sphere with marked points. Moreover, the counting can be mapped to counting the number of SU(2) intertwiners compatible with the spins that label the defects. The resulting BH entropy is proportional to a_H with logarithmic corrections ΔS=-3/2 \log a_H. Our treatment from first principles completely settles previous controversies concerning the counting of states.
description: Final form, to appear in Phys. Rev. Lett. Some extra details on the constraint algebra added, some details on the quantization have been omitted to comply with PRL length standards (they appear however in arXiv:1006.0634)

description: In ihrer Dissertation, die 2015 als Teil der Reihe Religiöse Kulturen im Europa der Neuzeit im Verlag Vandenhoeck & Ruprecht publiziert wurde, beschäftigt sich die Autorin mit der Thematik städtischer Funeralkultur und dem Modernitätsdiskurs im Bereich Hygienik respektive Friedhofreformen am Beispiel Krakaus. Ausgangspunkt der Studie ist das 19. Jahrhundert mit seiner „Professionalisierung, Rationalisierung, Funktionalisierung, Medikalisierung, Politisierung und Emotionalisierung – der sich verändernde Umgang mit dem Tod erscheint als ein ambivalenter und modernitätsspezifischer Prozess, der den Tod als ein eigentliches Kernthema der Religionsgemeinschaften anderen Orientierungen unterordnet. Mehr noch: Religionsgemeinschaften mussten einen Teil ihrer bisherigen exklusiven Kompetenz über das Bestattungswesen an Behörden und staatliche Stellen abtreten" (S. 14). Ausgehend von der Fragestellung, wie Religionsgemeinschaften auf diese Kompetenzverluste reagierten und sich die Dynamik zwischen religiösen und säkularen Akteuren entwickelte (S. 15), untersucht die vorliegende Arbeit die Veränderungen im Krakauer Friedhofs- und Bestattungswesen des 19. Jahrhundert in zehn Kapiteln. Krogner-Kornalik begründet diesen Schritt mit einer Zäsur im Bestattungswesen und einer steigenden Anzahl von Konflikten innerhalb unterschiedlicher Religionsgruppen (S. 27). Sie nutzt für ihre Studie einen mikrohistorischen Ansatz, der im Wesentlichen auf der Auswertung öffentlicher Quellen beruht. Dazu wurden Verordnungen zur Regulierung des Bestattungswesens, öffentliche Korrespondenzen sowie Verordnungsbücher in den Staats- und Nationalarchiven in Krakau und Wien herangezogen. Weiterhin fanden auch lokale, katholische und nicht polnischsprachige Periodika sowie Dokumente regionaler Kirchengemeinden Eingang in die vorliegende Studie.

description: Connolly stawia ciekawą hipotezę: porządek społeczny danego kraju jest pochodną kształtu jego gospodarki, przy czym kluczowe znaczenie mają więzi międzynarodowe i struktura eksportu. Jej weryfikacji mają posłużyć losy państw byłego Bloku Wschodniego – od Azerbejdżanu przez Bułgarię po Czechy. Można pomyśleć, że jest to wariant marksistowskich analiz związków między bazą a nadbudową, lecz nic bardziej mylnego. Książce daleko do myśli Marksa zarówno w podejściu, jak i rozmachu analiz. Niemniej monografia Connolly'ego sprawnie wpisuje się w debatę na temat konsekwencji transformacji ustrojowych w regionie. Debatę pozbawioną już mrzonek o „konwergencji", jakie często pojawiały się we wcześniejszych tranzytologicznych wypowiedziach. Zamiast tego otrzymujemy trzeźwą i pozbawioną wymiaru normatywnego analizę tego, jak potoczyły się historie państw Europy Wschodniej i Azji Środkowej po rozpadzie ZSRR.

description: Izabela Dahl untersucht in ihrer Dissertation die Identitätskonstruktionen polnischer Jüdinnen und Juden, die nach dem Zweiten Weltkrieg unter Zwang nach Schweden emigrierten. Mit ihrem transdisziplinären Forschungsansatz zeigt die Autorin Mechanismen sozialer Zugehörigkeiten und Ausschlussprozesse auf. Sie zeigt,wie die wirkungsgeschichtlichen Kontexte Polens und Schwedens die Identitätsformationsprozesse beeinflussten. Mit ihrer Monographie schließt die Autorin eine Lücke sowohl in der polnischen als auch in der schwedischen Geschichtsschreibung sowie der Identitäts- und Migrationsforschung.

description: In this paper, we present a protocol for computing the principal eigenvector of a collection of data matrices belonging to multiple semi-honest parties with privacy constraints. Our proposed protocol is based on secure multi-party computation with a semi-honest arbitrator who deals with data encrypted by the other parties using an additive homomorphic cryptosystem. We augment the protocol with randomization and obfuscation to make it difficult for any party to estimate properties of the data belonging to other parties from the intermediate steps. The previous approaches towards this problem were based on expensive QR decomposition of correlation matrices, we present an efficient algorithm using the power iteration method. We analyze the protocol for correctness, security, and efficiency.

description: We examine the star lattice Kitaev model whose ground state is a a chiral spin liquid. We fermionize the model such that the fermionic vacua are toric code states on an effective Kagome lattice. This implies that the Abelian phase of the system is inherited from the fermionic vacua and that time reversal symmetry is spontaneously broken at the level of the vacuum. In terms of these fermions we derive the Bloch-matrix Hamiltonians for the vortex free sector and its time reversed counterpart and illuminate the relationships between the sectors. The phase diagram for the model is shown to be a sphere in the space of coupling parameters around the triangles of the lattices. The abelian phase lies inside the sphere and the critical boundary between topologically distinct Abelian and non-Abelian phases lies on the surface. Outside the sphere the system is generically gapped except in the planes where the coupling parameters are zero. These cases correspond to bipartite lattice structures and the dispersion relations are similar to that of the original Kitaev honeycomb model. In a further analysis we demonstrate the three-fold non-Abelian groundstate degeneracy on a torus by explicit calculation.

description: Gegenstand des vorliegenden Bandes sind Sprache und Identität der Menschen, die ab 1945 die polnische Region Lebus, gelegen an der westlichen Grenze des nach Westen verschobenen Staates, besiedelten oder dort bereits zuvor gelebt hatten. Dazu führte Anna Zielińska, Professorin am Institut für Slawistik der Polnischen Akademie der Wissenschaften, Tiefeninterviews mit 137 Gewährspersonen aus 52 Ortschaften durch, z.T. gemeinsam mit Kolleginnen und Kollegen. Die Studie ist insofern innovativ, als sie die erste umfassende Untersuchung zur Sprachlandschaft der sogenannten „Wiedergewonnenen Gebiete" darstellt, die nicht von den ideologischen Verzerrungen linguistischer Forschung in der Volksrepublik Polen geprägt ist.
Spontaneous Emission in ultra-cold spin-polarised anisotropic Fermi Seas

description: We examine and explain the spatial emission patterns of ultracold excited fermions in anisotropic trapping potentials in the presence of a spin polarised Fermi sea of ground state atoms. Due to the Pauli principle, the Fermi sea modifies the available phase space for the recoiling atom and thereby modifies its decay rate and the probability of the emitted photon's direction. We show that the spatial anisotropies are due to an intricate interplay between Fermi energies and degeneracy values of specific energy levels and identify a regime in which the emission will become completely directional. Our results are relevant for recent advances in trapping and manipulating cold fermionic samples experimentally and give an example of a conceptually new idea for a directional photon source.

description: Public health surveillance systems likely underestimate the true prevalence and incidence of SARS-CoV-2 infection due to limited access to testing and the high proportion of subclinical infections in community-based settings. This ongoing prospective, observational study aimed to generate accurate estimates of the prevalence and incidence of, and risk factors for, SARS-CoV-2 infection among residents of a central North Carolina county. From this cohort, we collected survey data and nasal swabs every two weeks and venous blood specimens every month. Nasal swabs were tested for the presence of SARS-CoV-2 virus (evidence of active infection), and serum specimens for SARS-CoV-2-specific antibodies (evidence of prior infection). As of June 23, 2021, we have enrolled a total of 153 participants from a county with an estimated 76,285 total residents. The anticipated study duration is at least 24 months, pending the evolution of the pandemic. Study data are being shared on a monthly basis with North Carolina state health authorities and future analyses aim to compare study data to state-wide metrics over time. Overall, the use of a probability-based sampling design and a well-characterized cohort will enable collection of critical data that can be used in planning and policy decisions for North Carolina and may be informative for other states with similar demographic characteristics.

description: The Infinium MethylationEPIC BeadChip (EPIC) is a reliable method for measuring the DNA methylation of more than 850,000 CpG positions. In clinical and forensic settings, it is critical to be able to work with low DNA amounts without risking reduced reproducibility. We evaluated the EPIC for a range of DNA amounts using two-fold serial dilutions investigated on two different days. While the β-value distributions were generally unaffected by decreasing DNA amounts, the median squared Pearson’s correlation coefficient (R2) of between-days β-value comparisons decreased from 0.994 (500 ng DNA) to 0.957 (16 ng DNA). The median standard deviation of the β-values was 0.005 and up to 0.017 (median of medians: 0.014) for β-values around 0.6–0.7. With decreasing amounts of DNA from 500 ng to 16 ng, the percentage of probes with standard deviations ≤ 0.1 decreased from 99.9% to 99.4%. This study showed that high reproducibility results are obtained with DNA amounts in the range 125–500 ng DNA, while DNA amounts equal to 63 ng or below gave less reproducible results.

description: Consider the problem of optimally matching two measures on the circle, or equivalently two periodic measures on the real line, and suppose the cost of matching two points satisfies the Monge condition. We introduce a notion of locally optimal transport plan, motivated by the weak KAM (Aubry-Mather) theory, and show that all locally optimal transport plans are conjugate to shifts and that the cost of a locally optimal transport plan is a convex function of a shift parameter. This theory is applied to a transportation problem arising in image processing: for two sets of point masses on the circle, both of which have the same total mass, find an optimal transport plan with respect to a given cost function satisfying the Monge condition. In the circular case the sorting strategy fails to provide a unique candidate solution and a naive approach requires a quadratic number of operations. For the case of $N$ real-valued point masses we present an O(N |log epsilon|) algorithm that approximates the optimal cost within epsilon; when all masses are integer multiples of 1/M, the algorithm gives an exact solution in O(N log M) operations.

description: The study aimed to document the impact of the COVID-19 pandemic on the health and well-being of individuals with past and current eating disorders (ED) in Sweden. We re-contacted participants with a known lifetime history of ED from two previous Swedish studies. Participants completed an online survey about health and functioning at baseline early in the pandemic (Wave 1 ca May/June 2020; N= 982) and six months later (Wave 2 Dec/Jan 2020/21; N= 646). Three important patterns emerged: 1) higher current ED symptoms were associated with greater anxiety, worry, and pandemic-related ED symptom increase; 2) patterns were fairly stable across time, although a concerning percentage (23%) who were symptom-free at Wave 1 reported the re-emergence of symptoms at Wave 2; and 3) only a minority of participants (<50%) with a current ED were in treatment, and of those in treatment, many reported fewer treatment sessions and decreased quality of care. The COVID-19 pandemic appears to pose serious health challenges for individuals with an ED, whether currently symptomatic or in remission. We encourage health service providers and patient advocates to be alert to the needs of individuals with ED and to take active measures to ensure access to appropriate evidence-based care both during and following the pandemic.
