description: Magnetic resonance spectroscopy (MRS) allows the analysis of biochemical processes non invasively and in vivo. Still, its application in clinical diagnostics is rare. Routine MRS is limited to spatial, chemical and temporal resolutions of cubic centimetres, mM and minutes. In fact, the signal of many metabolites is strong enough for detection, but the resonances significantly overlap, exacerbating identification and quantification. In addition, the signals of water and lipids are much stronger and dominate the entire spectrum. To suppress the background and isolate selected signals, usually, relaxation times, J-coupling and chemical shifts are used. Here, we propose methods to isolate the signals of selected molecular groups within endogenous metabolites by using long-lived spin states (LLS). We exemplify the method by preparing the LLSs of coupled protons in the endogenous molecules N-acetyl-L-aspartic acid (NAA). First, we store polarization in long-lived, double spin states and then apply saturation pulses and double quantum filters to suppress background signals. We show that LLS can be used to selectively prepare and measure the signals of chosen metabolites or drugs in the presence of water, inhomogeneous field and highly concentrated fatty solutions. The pH measurement presented here is one of the possible applications.

description: We exhibit rigid rotations of spheres as distortion elements in groups of diffeomorphisms, thereby answering a question of J Franks and M Handel. We also show that every homeomorphism of a sphere is, in a suitable sense, as distorted as possible in the group Homeo(S^n), thought of as a discrete group. An appendix by Y de Cornulier shows that Homeo(S^n) has the strong boundedness property, recently introduced by G Bergman. This means that every action of the discrete group Homeo(S^n) on a metric space by isometries has bounded orbits.

Self-rated health and structural racism indicated by county-level racial inequalities in socioeconomic status : The role of urban-rural classification
Creators: name: Bell, Caryn N.
name: Owens-Young, Jessica L.
Publisher: name: American University
Year: 2023

description: Recent attention to the interrelationship between racism, socioeconomic status (SES) and health has led to a small, but growing literature of empirical work on the role of structural racism in population health. Area-level racial inequities in SES are an indicator of structural racism, and the associations between structural racism indicators and self-rated health are unknown. Further, because urban-rural differences have been observed in population health and are associated with different manifestations of structural racism, explicating the role of urban-rural classification is warranted. This study examined the associations between racial inequities in SES and self-rated health by county urban-rural classification. Using data from County Health Rankings and American Communities Surveys, black-white ratios of SES were regressed on rates of fair/poor health in U.S. counties. Racial inequities in homeownership were negatively associated with fair/poor health (β = −0.87, s.e. = 0.18), but racial inequities in unemployment were positively associated with fair/poor health (β = 0.03, s.e. = 0.01). The associations between structural racism and fair/poor health varied by county urban-rural classification. Potential mechanisms include the concentration of resources in racially segregated counties with high racial inequities that lead to better health outcomes, but are associated with extreme black SES disadvantage. Racial inequities in SES are a social justice imperative with implications for population health that can be targeted by urban-rural classification and other social contextual characteristics.

description: We investigate the correlated electrons in the magic-angle twisted bilayer graphene by using the slave-rotor mean-field theory. Owing to the extended figure of Wannier orbitals, we study the two-orbital cluster Hubbard model with spin-valley fourfold degeneracy, focusing around half filling of valence bands below the neutrality point. The theory predicts multiple Mott insulator phases at fractional fillings not only for integer charges per moir{é} site, and it demonstrates that long-range electron hopping is highly suppressed because multiple-charge excitations are induced. Furthermore, the Kekul{é} valence bond order is investigated and is found to extend the Mott insulator phases to occupy a finite doping region. Adjacent to Mott insulator phases, superconducting domes emerges by virtue of spin-valley fluctuations. This work has provided a primal understanding and interesting phenomena of the correlated system, and for its novel interaction the model might produce plenty of possibilities waiting to be explored.

description: Second-order topological superconductors (SOTSs) host localized Majorana fermions and provide a new platform for topological quantum computation. We propose a remarkable and feasible way to realize networks based on SOTSs which allow to nucleate and braid Majorana bound states (MBSs) in an all-electrical manner without fine-tuning. The proposed setups are scalable in a straightforward way and can accommodate any even number of MBSs. Moreover, the MBSs in the networks allow defining qubits whose states can be initialized and read out by measuring Josephson currents flowing between SOTS islands. Our proposal can be implemented in monolayers of $\text{FeTe}{}_{1-x}\text{Se}_{x}$, monolayers of 1T'-WTe$_2$, and inverted Hg(Cd)Te quantum wells in proximity to conventional superconductors.

description: We explore the deep ultraviolet (that is, short-distance) limit of the power spectrum (PS) and of the correlation function of a cold dark matter dominated Universe. While for large scales the PS can be written as a double series expansion, in powers of the linear PS and of the wavenumber $k$, we show that, in the opposite limit, it can be expressed via an expansion in powers of the form $1/k^{d+2n}$, where $d$ is the number of spatial dimensions, and $n$ is a non negative integer. The coefficients of the terms of the expansion are nonperturbative in the linear PS, and can be interpreted in terms of the probability density function for the displacement field, evaluated around specific configurations of the latter, that we identify. In the case of the Zel'dovich dynamics, these coefficients can be determined analytically, whereas for the exact dynamics they can be treated as fit, or nuisance, parameters. We confirm our findings with numerical simulations and discuss the necessary steps to match our results to those obtained for larger scales and to actual measurements.

description: We study the process $e^- + e^+ \to e^+ + e^+ + e^- + e^-$ for ILC and CLIC energy regimes, in the minimal 3-3-1 model framework. The main contributions, for the production of two bileptons each one decaying into two same-sign leptons, come from s-channel annihilation ({\it via} $γ, Z$ and ${Z^\prime}$) and t-channel electron exchange. We evaluate the number of events for an extra neutral gauge boson mass $M_{Z^\prime}$ in the range 1 TeV to 3 TeV. We compare some distributions from 3-3-1 model with the Standard Model background in order to extract a possible signature of the contribution of bilepton and ${Z^\prime}$ for the process. From our analysis we conclude that our results give clear signals for physics beyond the Standard Model in e$^-$ e$^+$ colliders.

description: Understanding the cosmogonic record encoded in the parent volatiles stored in cometary nuclei requires investigating whether evolution (thermal or otherwise) has modified the composition of short-period comets during successive perihelion passages. As the most volatile molecules systematically observed in comets, the abundances of CO, CH4, and C2H6 in short-period comets may serve to elucidate the interplay between natal conditions and post-formative evolution in setting present-day composition, yet secure measurements of CO and CH4 in Jupiter-family comets (JFCs) are especially sparse. The highly favorable 2018 apparition of JFC 21P/Giacobini–Zinner enabled a sensitive search for these hypervolatiles in a prototypical carbon-chain depleted comet. We observed 21P/Giacobini–Zinner with the iSHELL spectrograph at the NASA Infrared Telescope Facility on four pre-perihelion dates, two dates near-perihelion, and one post-perihelion date. We obtained detections of CO, CH4, and C2H6 simultaneously with H2O on multiple dates. We present rotational temperatures, production rates, and mixing ratios. Combined with previous work, our results may indicate that the hypervolatile coma composition of 21P/Giacobini–Zinner was variable across apparitions as well as within a particular perihelion passage, yet the spread in these measurements is a relatively small fraction of the variation in each molecule from comet to comet. We discuss the implications of our measured hypervolatile content of 21P/Giacobini–Zinner for the evolution of JFCs, and place our results in the context of findings from the Rosetta mission and ground-based studies of comets.
Superconducting mechanism for the cuprate Ba$_2$CuO$_{3+δ}$ based on a multiorbital Lieb lattice model

description: For the recently discovered cuprate superconductor $\mathrm{Ba_{2}CuO_{3+δ}}$, we propose a lattice structure which resembles the model considered by Lieb to represent the vastly oxygen-deficient material. We first investigate the stability of the Lieb-lattice structure, and then construct a multiorbital Hubbard model based on first-principles calculation. By applying the fluctuation-exchange approximation to the model and solving the linearized Eliashberg equation, we show that $s$-wave and $d$-wave pairings closely compete with each other, and, more interestingly, that the intra-orbital and inter-orbital pairings coexist. We further show that, if the energy of the $d_{3z^2-r^2}$ band is raised to make it "incipient" with the lower edge of the band close to the Fermi level within a realistic band filling regime, $s\pm$-wave superconductivity is strongly enhanced. We reveal an intriguing relation between the Lieb model and the two-orbital model for the usual K$_2$NiF$_4$ structure where a close competition between $s-$ and $d-$wave pairings is known to occur. The enhanced superconductivity in the present model is further shown to be related to an enhancement found previously in the bilayer Hubbard model with an incipient band.

The role of vocal consistency in bird communication, a case study in the blue tit (Cyanistes Caeruleus)

description: Birdsong is a multidimensional acoustic signal used for communication during intra- and intersexual interactions. The anatomical and behavioural adaptations related to sophisticated phonation skills indicate there are directional selection pressures shaping phonation mechanisms in songbirds. The level of neuro-motor challenge displayed while singing is normally referred to as vocal performance of song. Theoretical and empirical work has shown that vocal performance is related to individual quality and is meaningful during communication. Here, I use the blue tit (Cyanistes caeruleus) as a model species to investigate the communicative value of vocal performance in birdsong with particular emphasis on vocal consistency. Vocal consistency, as the ability to reproduce the same song element with minimal variation, has been proposed as an honest signal of individual quality in songbirds. In line with this hypothesis, I found that higher vocal consistency in males was preferred by females and was associated with increased reproductive success. I also provide evidence to validate the Spectral Cross-Correlation method used to measure vocal consistency, by showing it is sensitive to acoustic variation in natural birdsong. Although vocal consistency may be meaningful by itself, I built a multi-species database to investigate possible interactions of vocal consistency with other aspects of song. The results suggest there is a general trade-off between vocal performance within song and song length in birds. Following this finding, I conducted two playback experiments that showed that 1) long songs elicited a stronger response from territorial males than short songs but 2) that long songs with reduced vocal consistency triggered a lower response from territorial males, compared with short songs of high vocal consistency. These playback experiments indicated there is communicative value in the performance trade-off between song length and vocal consistency. Finally, I provide evidence that female song is frequent in blue tits and contextual behaviour data suggest it plays a role in intrasexual competition, similar to male song. However, during dawn chorus, males but not females were observed singing. These contextual differences indicate that female song may not be subjected to strong selection pressures related to seeking copulations. I hypothesize that such functional differences may relate to sexual differences in song parameters as females sang with lower song diversity and lower vocal performance than male.

description: The exact or Wilson renormalization group equations can be formulated as a functional Fokker-Planck equation in the infinite-dimensional configuration space of a field theory, suggesting a stochastic process in the space of couplings. Indeed, the ordinary renormalization group differential equations can be supplemented with noise, making them into stochastic Langevin equations. Furthermore, if the renormalization group is a gradient flow, the space of couplings can be endowed with a supersymmetric structure a la Parisi-Sourlas. The formulation of the renormalization group as supersymmetric quantum mechanics is useful for analysing the topology of the space of couplings by means of Morse theory. We present simple examples with one or two couplings.

description: We compare different methodologies (in situ and bulk) for obtaining oxygen isotope (δ18O) and elemental ratios in the benthic foraminifera genus Uvigerina from ODP Site 1015, (California Margin), to assess what new information can be obtained with high-resolution in situ techniques. Specimens were prepared in epoxy mounts and exposed in cross-section such that multiple high-resolution analyses could be completed on the same shells using both Secondary Ionization Mass Spectrometry (SIMS) and Laser Ablation Inductively Coupled Mass Spectrometry (LA-ICP-MS). We also measured elemental ratio data using LA-ICP-MS depth-profile measurements on whole, uncast foraminifera and elemental ratio and δ18O with standard bulk techniques using the same species of benthic foraminifera from the same sediment sub-samples. Comparison of the data collected by the different methodologies indicates that there is a consistent offset of ~0.9 ± 0.1‰ between SIMS and bulk analysis of δ18O in these samples. The in situ laser data studied in epoxy mount is correlated with the foraminifera bulk measurements for both Mg and Sr, whereas the in situ depth-profile laser measurements of Mg and Sr from whole foraminifera are less correlated with the bulk measurements. We also observe that the intra-shell variability for each of the proxies is larger than the analytical error and does not follow chamber number. We propose that the δ18O, Mg, and Sr variability within and between single specimens at this site is linked to some combination of measurement bias, vital effects, and variable environmental conditions in the pore water where the tests were precipitated. This information can in turn be related to the regional setting of the site.

Circuit optimization of Hamiltonian simulation by simultaneous diagonalization of Pauli clusters

Year: 2020
Subjects: subject: Quantum Physics (quant-ph)

description: Many applications of practical interest rely on time evolution of Hamiltonians that are given by a sum of Pauli operators. Quantum circuits for exact time evolution of single Pauli operators are well known, and can be extended trivially to sums of commuting Paulis by concatenating the circuits of individual terms. In this paper we reduce the circuit complexity of Hamiltonian simulation by partitioning the Pauli operators into mutually commuting clusters and exponentiating the elements within each cluster after applying simultaneous diagonalization. We provide a practical algorithm for partitioning sets of Paulis into commuting subsets, and show that the proposed approach can help to significantly reduce both the number of CNOT operations and circuit depth for Hamiltonians arising in quantum chemistry. The algorithms for simultaneous diagonalization are also applicable in the context of stabilizer states; in particular we provide novel four- and five-stage representations, each containing only a single stage of conditional gates.
title: Communication and information: the experience of radiotherapy patients.
Creators: name: Gamble, Karen
Publisher: name: The Open University
Year: 1996

description: The purpose of this study was to explore patient's own descriptive accounts of their experiences of having cancer and undergoing radiotherapy treatment. The respondents involved were suffering from either cancer of the head and neck region or lung cancer. The study focused on "information-giving", in particular eliciting data about misconceptions, missing information and valued information. In addition, material which described another, perhaps unconscious level of communication between health professionals and patients was drawn from the interviews. The methodology employed was of a qualitative nature and predominantly influenced by "grounded theory" (Glaser and Strauss, 1967), where the meanings attached to events are described and explained. However, the "phenomenological" perspective was also influential, in which significance is given to the "lived experience" of the participants (Morse and Johnson, 1991). The method used to obtain data was "interviewing", via semi-structured, audio-taped interviews. Data gathering was approached by way of obtaining "narrative accounts"or stories from the respondents. Thus, the analysis chapters are arranged in a temporal fashion, representing the beginning, middle and "sense of an ending" to the stories (Sarbin, 1986). Three underlying themes emerged from the analysis; hope, fear and uncertainty. The study investigated these themes, and explicated the relation of them to various events. For instance, "hope" occurred in relation to treatment and faith in the hospital staff. "Fear" occurred in relation to recurrence of the cancer and death. "Uncertainty" was noted in connection with prognosis and treatment options. There was also evidence to suggest that health professionals played a role in boosting or decreasing self-esteem (similar to Charmaz, 1983). In particular, this study highlighted that there seemed to be a desire from the cancer sufferers' to obtain a verbal acknowledgement from staff, of the adversity they had overcome.

description: We compare different methodologies (in situ and bulk) for obtaining oxygen isotope (δ18O) and elemental ratios in the benthic foraminifera genus Uvigerina from ODP Site 1015, (California Margin), to assess what new information can be obtained with high-resolution in situ techniques. Specimens were prepared in epoxy mounts and exposed in cross-section such that multiple high-resolution analyses could be completed on the same shells using both Secondary Ionization Mass Spectrometry (SIMS) and Laser Ablation Inductively Coupled Mass Spectrometry (LA-ICP-MS). We also measured elemental ratio data using LA-ICP-MS depth-profile measurements on whole, uncast foraminifera and elemental ratio and δ18O with standard bulk techniques using the same species of benthic foraminifera from the same sediment sub-samples. Comparison of the data collected by the different methodologies indicates that there is a consistent offset of ~0.9 ± 0.1‰ between SIMS and bulk analysis of δ18O in these samples. The in situ laser data studied in epoxy mount is correlated with the foraminifera bulk measurements for both Mg and Sr, whereas the in situ depth-profile laser measurements of Mg and Sr from whole foraminifera are less correlated with the bulk measurements. We also observe that the intra-shell variability for each of the proxies is larger than the analytical error and does not follow chamber number. We propose that the δ18O, Mg, and Sr variability within and between single specimens at this site is linked to some combination of measurement bias, vital effects, and variable environmental conditions in the pore water where the tests were precipitated. This information can in turn be related to the regional setting of the site.
Supply of bank loans and business debts : A view from historical bankruptcy cases

description: As bank loans fell in the 2008 crisis, business bankruptcy increased. To study how bank loans affect business balance sheets and bankruptcy, we use new data on bankrupt businesses in Missouri between 1898 and 1942. We confirm that when banks curtail loans, courts see more bankruptcies among businesses with high exposure to bank debt. To reduce real volatility, policy-makers can set tough bank liquidity requirements in the upswing of business cycle but allow weaker requirements in the downswing. We also find that between 1914 and 1933, businesses in St. Louis were more sensitive to changes in bank loans than businesses in Kansas City, probably due to the tight monetary policy conducted by the conservative St. Louis Fed. The Glass-Steagall Act weakened the relationship between bank loans and business debt structure. The takeaway is that lender-of-last-resort practices stabilize both the financial sector and the real economy.
A Balanced Approach of Rapid Genetic Exploration and Surrogate Exploitation for Hyperparameter Optimization

description: This paper proposes a new method for hyperparameter optimization (HPO) that balances exploration and exploitation. While evolutionary algorithms (EAs) show promise in HPO, they often struggle with effective exploitation. To address this, we integrate a linear surrogate model into a genetic algorithm (GA), allowing for smooth integration of multiple strategies. This combination improves exploitation performance, achieving an average improvement of 1.89 percent (max 6.55 percent, min -3.45 percent) over existing HPO methods.

description: We prove the Existential Closedness conjecture for the differential equation of the $j$-function and its derivatives. It states that in a differentially closed field certain equations involving the differential equation of the $j$-function have solutions. Its consequences include a complete axiomatisation of $j$-reducts of differentially closed fields, a dichotomy result for strongly minimal sets in those reducts, and a functional analogue of the Modular Zilber-Pink with Derivatives conjecture.

description: We study general conditions under which the computations of the index of a perturbed Dirac operator $D_{s}=D+sZ$ localize to the singular set of the bundle endomorphism $Z$ in the semi-classical limit $s\to \infty $. We show how to use Witten's method to compute the index of $D$ by doing a combinatorial computation involving local data at the nondegenerate singular points of the operator $Z$. In particular, we provide examples of novel deformations of the de Rham operator to establish new results relating the Euler characteristic of a spin$^{c}$ manifold to maps between its even and odd spinor bundles. The paper contains a list of the current literature on the subject.

Speed up random walk by leveraging community affiliation information

description: Large online networks are most massive and opulent data sources these days. The inherent growing demands of analyses related data fetching conflict greatly with network providers’ efforts to protect their digital assets as well as users’ increasing awareness of privacy. Restrictions on web interfaces of online networks prevent third party researchers from gathering sufficient data and further global images of these networks are also hidden. Under such circumstances, only techniques like random walk approaches that can run under local neighborhood access will be adopted to fulfill large online network sampling tasks. Meanwhile, the presence of highly clustered community like structure in large networks leads to random walk’s poor conductance, causing intolerable and hard-to-foresee long mixing time before useful samples can be collected. With lack of techniques incorporate online network topology features being the context, in this paper we focus on taking use of community affiliation information that possibly comes with metadata when querying objects in online networks, and proposed a speeded version of random walk by raising the probability of inter-community edges being selected. Assuming the community structure is well established as promised, the community speeded random walk expects better conductance and faster convergence. Our method forces the sampler to travel rapidly among different communities that conquers the bottlenecks and thus the samples being collected are of higher quality. We also consider the scenario when community affiliation is not directly available, where we apply feature selection algorithms to select features as community.
GeoFusion: Geometric Consistency informed Scene Estimation in Dense Clutter

description: We propose GeoFusion, a SLAM-based scene estimation method for building an object-level semantic map in dense clutter. In dense clutter, objects are often in close contact and severe occlusions, which brings more false detections and noisy pose estimates from existing perception methods. To solve these problems, our key insight is to consider geometric consistency at the object level within a general SLAM framework. The geometric consistency is defined in two parts: geometric consistency score and geometric relation. The geometric consistency score describes the compatibility between object geometry model and observation point cloud. Meanwhile, it provides a reliable measure to filter out false positives in data association. The geometric relation represents the relationship (e.g. contact) between geometric features (e.g. planes) among objects. The geometric relation makes the graph optimization for poses more robust and accurate. GeoFusion can robustly and efficiently infer the object labels, 6D object poses, and spatial relations from continuous noisy semantic measurements. We quantitatively evaluate our method using observations from a Fetch mobile manipulation robot. Our results demonstrate greater robustness against false estimates than frame-by-frame pose estimation from the state-of-the-art convolutional neural network.
