description: The non-Hermitian skin effect, as a unique feature of non-Hermitian systems, will break the topological energy braiding of the Bloch bands in open boundary systems. Going beyond the Bloch band theory, we unveil the energy braiding of the non-Bloch bands by introducing a one-dimensional non-Hermitian tight-binding model. We find an entirely new generic class of topological non-Bloch bands such as Hopf link, which is generally generated by the non-Hermitian skin effect. The energy braiding is topologically robust against any perturbations without gap closing. Furthermore, non-Bloch topological invariants are proposed based on the generalized Brillouin zone to characterize the topology of these non-Bloch bands. The topological phase transition between the distinct phases occurs with the non-Bloch bands touching at exceptional points. We hope that our work can shed light on the topological energy braiding of the non-Bloch bands for non-Hermitian systems.

data management

description: Automatic Weather Stations (AWS) deployed in the context of research projects provide very valuable data thanks to the flexibility they offer in term of measured meteorological parameters, choice of sensors and quick deployment and redeployment. However this flexibility is a challenge in terms of metadata and data management. Traditional approaches based on networks of standard stations can not accommodate these needs and often no tools are available to manage these research AWS, leading to wasted data periods because of difficult data reuse, low reactivity in identifying potential measurement problems, and lack of metadata to document what happened.

The Data Access Made Easy (DAME) effort is our answer to these challenges. At its core, it relies on the mature and flexible open source MeteoIO meteorological pre-processing library. It was originally developed as a flexible data processing engine for the needs of numerical models consuming meteorological data and further developed as a data standardization engine for the Global Cryosphere Watch (GCW) of the World Meteorological Organization (WMO). For each AWS, a single configuration file describes how to read and parse the data, defines a mapping between the available fields and a set of standardized names and provides relevant Attribute Conventions Dataset Discovery (ACDD) metadata fields, if necessary on a per input file basis. Low level data editing is also available, such as excluding a given sensor, swapping sensors or merging data from another AWS, for any given time period. Moreover an arbitrary number of filters can be applied on each meteorological parameter, restricted to specific time periods if required. This allows to describe the whole history of an AWS within a single configuration file and to deliver a single, consistent, standardized output file possibly spanning many years, many input data files and many changes both in format and available sensors. Finally, all configuration files are kept in a git repository in order to document their history.

A basic email-based interface has been developed that allows to create new configuration files, modify an existing configuration file or request data on-demand for any time period. Every hour, the data for all available configuration files is regenerated for the last 13 months and stored on a shared drive so all are able to access the current data without even having to submit a request. A table is generated showing all warnings or errors produced during the data generation along with some metadata such as the data owner email in order for the data owner to quickly spot troublesome AWS.

description: A systematic review with meta-analysis is often considered the highest level of evidence in ranking the literature. The term “systematic review” refers to the overall publication, while the term “meta-analysis” indicates that the review includes a statistical synthesis of results from at least 2 of the included studies. Not all systematic reviews include a meta-analysis, but meta-analyses are always within a systematic review. There are different types of metaanalyses in which statistical analysis can be performed, including network meta-analysis and Bayesian meta-analysis. While these meta-analysis methods can vary, the majority are “variations on a weighted average of the effect estimates from the different studies.”

description: As exoplanet characterisation relies on the detection of resolved features, analysis can be improved with high signal-to-noise ratios (SNR) that are possible to obtain with modern spectrographs like CRIRES+. However, obtaining high SNR through adjusting exposure times is trade-off that results in smearing of spectral features due to variable Doppler shift and in averaging blocked stellar radiation originating from different parts of the stellar disk. There is therefore a need to establish what the optimal compromise is between the SNR and time resolution for a given target. We will discuss potential approaches for establishing the optimal parameters for observing transiting exoplanets with spectroscopic instruments such as CRIRES+ using simulated spectra, cross-correlation, and other statistical methods. This will be particularly relevant for planning observational studies of close-in planets around cool stars with more complex stellar spectra.

Tests of the parametrizations of Fragmentation Functions using data on inclusive pion and kaon production in unpolarized $pp$ collisions from the STAR collaboration and at the NICA project

description: The goal of this study is to check which, if any, of the published versions of the pion and kaon fragmentation functions is compatible with the STAR data on semi-inclusive pion and kaon production in proton-proton collisions, and on the basis of this analysis to make reliable predictions for the $p_T$ spectra of the pions and kaons in inclusive pion and kaon production at the future NICA proton-proton collider. The calculations are carried out in next-to-leading order (NLO) of perturbative quantum chromodynamics (pQCD), using the well tested CTEQ6 parton distributions. We consider the following pion and kaon fragmentation functions (FFs) -- DSEHS-14, DSEHS-17, LSS-15, HKNS-07 and AKK-08. Our analysis shows that within the experimental errors all tested sets of fragmentation functions provide a good fit to STAR data at the c.m. energy $ \sqrt{S} = 200\, {\rm GeV} $, and the best ones are both LSS-15 and DSEHS-14 for pions and DSEHS-17 for kaons. From comparison of the LO and NLO results it is clear that the latter fit data much better, specially in the region of small $p_T$. The NLO cross sections are also less scale-$Q^2$ dependent, where $p_T/2\leqslant Q \leqslant 2p_T$, than the LO ones. In order to make predictions for NICA energies, we compare the NLO pQCD results with the existing experimental BES STAR data on semi-inclusive hadron production in the most peripheral Au+Au collisions where the nuclear effects can be neglected. The comparison for lower energy scales, like at NICA, shows that a purely pQCD approach is inadequate and suggests the necessity to take into account also higher-order effects of initial-state soft-gluon radiation. Nevertheless, these data on the $p_T$ spectra of $π^+$, $K^+$ and also the ratios $π^-/π^+$ and $K^-/K^+$ seem favour LSS-15 and DSEHS-14 FFs for pions and DSEHS-17 for kaons, similarly as at the energy scale $ \sqrt{S} = 200\, {\rm GeV} $.

Centrality and rapidity dependence of inclusive jet production in $\sqrt{s_\mathrm{NN}} = 5.02$ TeV proton-lead collisions with the ATLAS detector

description: Measurements of the centrality and rapidity dependence of inclusive jet production in $\sqrt{s_\mathrm{NN}} = 5.02$ TeV proton--lead ($p$+Pb) collisions and the jet cross-section in $\sqrt{s} = 2.76$ TeV proton--proton collisions are presented. These quantities are measured in datasets corresponding to an integrated luminosity of 27.8 nb$^{-1}$ and 4.0 pb$^{-1}$, respectively, recorded with the ATLAS detector at the Large Hadron Collider in 2013. The $p$+Pb collision centrality was characterised using the total transverse energy measured in the pseudorapidity interval $-4.9 < η< -3.2$ in the direction of the lead beam. Results are presented for the double-differential per-collision yields as a function of jet rapidity and transverse momentum ($p_\mathrm{T}$) for minimum-bias and centrality-selected $p$+Pb collisions, and are compared to the jet rate from the geometric expectation. The total jet yield in minimum-bias events is slightly enhanced above the expectation in a $p_\mathrm{T}$-dependent manner but is consistent with the expectation within uncertainties. The ratios of jet spectra from different centrality selections show a strong modification of jet production at all $p_\mathrm{T}$ at forward rapidities and for large $p_\mathrm{T}$ at mid-rapidity, which manifests as a suppression of the jet yield in central events and an enhancement in peripheral events. These effects imply that the factorisation between hard and soft processes is violated at an unexpected level in proton-nucleus collisions. Furthermore, the modifications at forward rapidities are found to be a function of the total jet energy only, implying that the violations may have a simple dependence on the hard parton-parton kinematics.

The G protein biased serotonin 5-HT2A receptor agonist lisuride exerts anti-depressant drug-like activities in mice

description: There is now evidence from multiple Phase II clinical trials that psychedelic drugs can exert long-lasting anxiolytic, anti-depressant, and anti-drug abuse (nicotine and ethanol) effects in patients. Despite these benefits, the hallucinogenic actions of these drugs at the serotonin 2A receptor (5-HT2AR) limit their clinical use in diverse settings. Activation of the 5-HT2AR can stimulate both G protein and β-arrestin (βArr) -mediated signaling. Lisuride is a G protein biased agonist at the 5-HT2AR and, unlike the structurally-related lysergic acid diethylamide (LSD), the drug does not typically produce hallucinations in normal subjects at routine doses. Here, we examined behavioral responses to lisuride, in wild-type (WT), βArr1-knockout (KO), and βArr2-KO mice. In the open field, lisuride reduced locomotor and rearing activities, but produced a U-shaped function for stereotypies in both βArr lines of mice. Locomotion was decreased overall in βArr1-KOs and βArr2-KOs relative to wild-type controls. Incidences of head twitches and retrograde walking to lisuride were low in all genotypes. Grooming was decreased in βArr1 mice, but was increased then decreased in βArr2 animals with lisuride. Serotonin syndrome-associated responses were present at all lisuride doses in WTs, but they were reduced especially in βArr2-KO mice. Prepulse inhibition (PPI) was unaffected in βArr2 mice, whereas 0.5 mg/kg lisuride disrupted PPI in βArr1 animals. The 5-HT2AR antagonist MDL100907 failed to restore PPI in βArr1 mice, whereas the dopamine D2/D3 antagonist raclopride normalized PPI in WTs but not in βArr1-KOs. Clozapine, SCH23390, and GR127935 restored PPI in both βArr1 genotypes. Using vesicular monoamine transporter 2 mice, lisuride reduced immobility times in tail suspension and promoted a preference for sucrose that lasted up to 2 days. Together, it appears βArr1 and βArr2 play minor roles in lisuride’s actions on many behaviors, while this drug exerts anti-depressant drug-like responses without hallucinogenic-like activities.

description: We describe how multirefence dynamic correlation theories can be naturally obtained as single-reference correlation theories in a canonically transformed frame. Such canonically transformed correlation theories are very simple and involve identical expressions to their single-reference counterparts. The corresponding excitations involve quasiparticles rather than the bare particles of the system. High-order density matrices (or their approximations) and the numerical metric instabilities common to multireference correlation theories do not appear. As an example, we formulate the Bogoliubov canonically transformed version of second-order Møller-Plesset perturbation theory and demonstrate its performance in hydrogen, water, nitrogen, and BeH$_2$ bond dissociation.

description: We investigate the influence of gravitational waves on a freely falling hydrogen atom by analyzing the dynamics of the bound electron described by the Dirac equation in the curved spacetime of a gravitational wave. From this, we derive the corresponding Dirac Hamiltonian in the Local Inertial Frame of the atom, assuming gravitational waves are described by the linearized theory of General Relativity. To maintain meaningful physical interpretations while obtaining a non-relativistic description, we employ the Foldy-Wouthuysen transformation. Through the analysis of resulting interaction terms and comparison with flat spacetime counterparts, valuable insights into the effects of gravitational waves on the hydrogen atom are gained. Additionally, we explore selection rules governing the coupling between gravitational waves and the atom and utilize first-order perturbation theory to quantify the induced energy shifts and spectral line splitting. This investigation contributes to our understanding of the interplay between quantum systems and gravitational waves, which could lead to alternative method of gravitational waves indirect detection. However, measuring such tiny energy shifts would require a telescope with very high spectral resolution.

description: We investigated the accuracy of CEUS for characterizing cystic and solid kidney lesions in patients with chronic kidney disease (CKD). Cystic lesions are assessed using Bosniak criteria for computed tomography (CT) and magnetic resonance imaging (MRI); however, in patients with moderate to severe kidney disease, CT and MRI contrast agents may be contraindicated. Contrast-enhanced ultrasound (CEUS) is a safe alternative for characterizing these lesions, but data on its performance among CKD patients are limited. We performed flash replenishment CEUS in 60 CKD patients (73 lesions). Final analysis included 53 patients (63 lesions). Four readers, blinded to true diagnosis, interpreted each lesion. Reader evaluations were compared to true lesion classifications. Performance metrics were calculated to assess malignant and benign diagnoses. Reader agreement was evaluated using Bowker’s symmetry test. Combined reader sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for diagnosing malignant lesions were 71%, 75%, 45%, and 90%, respectively. Sensitivity (81%) and specificity (83%) were highest in CKD IV/V patients when grouped by CKD stage. Combined reader sensitivity, specificity, PPV, and NPV for diagnosing benign lesions were 70%, 86%, 91%, and 61%, respectively. Again, in CKD IV/V patients, sensitivity (81%), specificity (95%), and PPV (98%) were highest. Inter-reader diagnostic agreement varied from 72% to 90%. In CKD patients, CEUS is a potential low-risk option for screening kidney lesions. CEUS may be particularly beneficial for CKD IV/V patients, where kidney preservation techniques are highly relevant.

description: We introduce a method for computing probabilities for spontaneous activity and propagation fail- ure of the action potential in spatially extended, conductance-based neuronal models subject to channel noise, based on statistical properties of the membrane potential. We compare different estimators with respect to the quality of detection, computational costs and robustness and propose the integral of the membrane potential along the axon as an appropriate estimator to detect both spontaneous activity and propagation failure. Performing a model reduction we achieve a simplified analytical expression based on the linearization at the resting potential (resp. the traveling action potential). This allows to approximate the probabilities for spontaneous activity and propagation failure in terms of (classical) hitting probabilities of one-dimensional linear stochastic differential equations. The quality of the approximation with respect to the noise amplitude is discussed and illustrated with numerical results for the spatially extended Hodgkin-Huxley.

description: We present a novel meta-learning approach for 6D pose estimation on unknown objects. In contrast to ``instance-level" and ``category-level" pose estimation methods, our algorithm learns object representation in a category-agnostic way, which endows it with strong generalization capabilities across object categories. Specifically, we employ a neural process-based meta-learning approach to train an encoder to capture texture and geometry of an object in a latent representation, based on very few RGB-D images and ground-truth keypoints. The latent representation is then used by a simultaneously meta-trained decoder to predict the 6D pose of the object in new images. Furthermore, we propose a novel geometry-aware decoder for the keypoint prediction using a Graph Neural Network (GNN), which explicitly takes geometric constraints specific to each object into consideration. To evaluate our algorithm, extensive experiments are conducted on the \linemod dataset, and on our new fully-annotated synthetic datasets generated from Multiple Categories in Multiple Scenes (MCMS). Experimental results demonstrate that our model performs well on unseen objects with very different shapes and appearances. Remarkably, our model also shows robust performance on occluded scenes although trained fully on data without occlusion. To our knowledge, this is the first work exploring \textbf{cross-category level} 6D pose estimation.

description: Attributed graph clustering is one of the most fundamental tasks among graph learning field, the goal of which is to group nodes with similar representations into the same cluster without human annotations. Recent studies based on graph contrastive learning method have achieved remarkable results when exploit graph-structured data. However, most existing methods 1) do not directly address the clustering task, since the representation learning and clustering process are separated; 2) depend too much on data augmentation, which greatly limits the capability of contrastive learning; 3) ignore the contrastive message for clustering tasks, which adversely degenerate the clustering results. In this paper, we propose a Neighborhood Contrast Framework for Attributed Graph Clustering, namely NCAGC, seeking for conquering the aforementioned limitations. Specifically, by leveraging the Neighborhood Contrast Module, the representation of neighbor nodes will be 'push closer' and become clustering-oriented with the neighborhood contrast loss. Moreover, a Contrastive Self-Expression Module is built by minimizing the node representation before and after the self-expression layer to constraint the learning of self-expression matrix. All the modules of NCAGC are optimized in a unified framework, so the learned node representation contains clustering-oriented messages. Extensive experimental results on four attributed graph datasets demonstrate the promising performance of NCAGC compared with 16 state-of-the-art clustering methods.

description: Accurate regulation of internal body temperature is required in order to survive and maintain optimal function. The natural ageing process is associated with a progressive deterioration of the structure and function of the cardiovascular and nervous system, which reduces an individual’s ability to thermoregulate. As a result, older individuals are more susceptible to heat and cold related illnesses and injury compared to their younger counterparts. Within the currently available literature there is a large body of research assessing the influence of ageing on several thermoregulatory responses. However, these studies typically focus on a single body region or a small number of regions; hence a comprehensive overview of age-related changes in these responses is currently lacking. Therefore, the aim of this research was to adopt a body mapping approach to assess the regional and age-related differences in thermal sensitivity, sweating and skin temperature in both young and older individuals.Within this thesis, the current available literature on thermoregulation and ageing is first introduced in Chapter 1 and critically reviewed in Chapter 2. This is then followed by the five laboratory studies which are presented individually in Chapter’s 3 to 7 (overview presented in table below). Each chapter has its own detailed methodology section and due to the variety of different techniques and procedures used in each study, this thesis does not include a ‘general methods’ chapter.

description: We extend and apply a rigorous renormalisation group method to study critical correlation functions, on the 4-dimensional lattice $\mathbb{Z}^4$, for the weakly coupled $n$-component $|φ|^4$ spin model for all $n \geq 1$, and for the continuous-time weakly self-avoiding walk. For the $|φ|^4$ model, we prove that the critical two-point function has $|x|^{-2}$ (Gaussian) decay asymptotically, for $n \ge 1$. We also determine the asymptotic decay of the critical correlations of the squares of components of $φ$, including the logarithmic corrections to Gaussian scaling, for $n \geq 1$. The above extends previously known results for $n = 1$ to all $n \ge 1$, and also observes new phenomena for $n > 1$, all with a new method of proof. For the continuous-time weakly self-avoiding walk, we determine the decay of the critical generating function for the "watermelon" network consisting of p weakly mutually- and self-avoiding walks, for all $p \ge 1$, including the logarithmic corrections. This extends a previously known result for $p = 1$, for which there is no logarithmic correction, to a much more general setting. In addition, for both models, we study the approach to the critical point and prove existence of logarithmic corrections to scaling for certain correlation functions. Our method gives a rigorous analysis of the weakly self-avoiding walk as the $n = 0$ case of the $|φ|^4$ model, and provides a unified treatment of both models, and of all the above results.

description: Background Use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) in elderly patients is controversial because of presumed poor outcome. Our primary aim was to determine the influence of advanced age on short- and long-term outcome; the secondary aim was to analyze risk factors for impaired outcome. Methods Between January 2006 and June 2020, 645 patients underwent VA-ECMO implantation in our department. The patients were categorized into four groups:<50, 50–59.9, 60–69.9 and ≥70 years old. Data were retrospectively analyzed for short- and long-term outcome. Risk factors for in-hospital mortality and mortality during follow-up were assessed using multivariate regression analysis. Results VA-ECMO support duration was comparable in all age groups (median 3 days). Weaning rates were 60.8%/n = 104 (<50 years), 51.4%/n = 90 (50–59.9 years), 58.8%/n = 107 (60–69.9), and 67.5%/n = 79 (≥70, p = 0.048). Hospital mortality was highest in the patients aged 50–59.9 years (68%/n = 119), but not in the elderly patients (60–69.9, ≥70:62.1%/n = 113, 58,1%/n = 68). At discharge, the cerebral performance category scores were superior in the patients <50 years. Multivariate logistic regression analysis revealed chronic kidney failure requiring hemodialysis, duration of cardiopulmonary resuscitation, and elevated blood lactate levels before VA-ECMO, but not age as predictors of in-hospital mortality. Cox's regression disclosed age as relevant risk factor for death during follow-up. The patients' physical ability was comparable in all age groups. Conclusion VA-ECMO support should not be declined in patients only because of advanced age. Mortality and neurological status at hospital discharge and during follow-up were comparable in all age groups.

Singular perturbation by bending for an adhesive obstacle problem

description: A free boundary problem arising from materials science is studied in one-dimensional case. The problem studied here is an obstacle problem for the non-convex energy consisting of a bending energy, tension and an adhesion energy. If the bending energy, which is a higher order term, is deleted then "edge" singularities of the solutions (surfaces) may occur at the free boundary as Alt-Caffarelli type variational problems. The main result of this paper is to give a singular limit of the energy utilizing the notion of $Γ$-convergence, when the bending energy can be regarded as a perturbation. This singular limit energy only depends on the state of surfaces at the free boundary as seen in singular perturbations for phase transition models.

description: Particle accelerators as photon sources are advanced tools in studying the structure and dynamical properties of matter. The present workhorses of these sources are storage ring-based synchrotron radiation facilities and linear accelerator-based free-electron lasers, delivering light with high repetition rate and high peak brilliance (power), respectively. The steady-state microbunching (SSMB) mechanism was proposed to bridge the gap of these two kinds of sources to generate high-average-power, high-repetition-rate coherent radiation in an electron storage ring. Such a novel light source promises new possibilities for accelerator photon science and industry applications, for example in ultra-high-energy-resolution angle-resolved photoemission spectroscopy and extreme ultraviolet lithography. The six orders of magnitude extrapolation of the electron bunch length in an SSMB storage ring compared to that of a conventional ring provides tremendous opportunities for accelerator physics research. This dissertation is devoted to the theoretical and experimental investigations of SSMB, with important results achieved. The work presented can be summarized as: first, how to realize SSMB; second, what radiation characteristics can we obtain from the formed SSMB; and third, experimentally demonstrate the working mechanism of SSMB in a real machine.

$k$-POD: A Method for $k$-Means Clustering of Missing Data

description: The $k$-means algorithm is often used in clustering applications but its usage requires a complete data matrix. Missing data, however, is common in many applications. Mainstream approaches to clustering missing data reduce the missing data problem to a complete data formulation through either deletion or imputation but these solutions may incur significant costs. Our $k$-POD method presents a simple extension of $k$-means clustering for missing data that works even when the missingness mechanism is unknown, when external information is unavailable, and when there is significant missingness in the data.

description: Clustering is an unsupervised machine learning methodology where unlabeled elements/objects are grouped together aiming to the construction of well-established clusters that their elements are classified according to their similarity. The goal of this process is to provide a useful aid to the researcher that will help her/him to identify patterns among the data. Dealing with large databases, such patterns may not be easily detectable without the contribution of a clustering algorithm. This article provides a deep description of the most widely used clustering methodologies accompanied by useful presentations concerning suitable parameter selection and initializations. Simultaneously, this article not only represents a review highlighting the major elements of examined clustering techniques but emphasizes the comparison of these algorithms' clustering efficiency based on 3 datasets, revealing their existing weaknesses and capabilities through accuracy and complexity, during the confrontation of discrete and continuous observations. The produced results help us extract valuable conclusions about the appropriateness of the examined clustering techniques in accordance with the dataset's size.

title: How do the police define, identify, and respond to vulnerability?
Creators: name: Keay, Scott
Publisher: name: University of Central Lancashire

description: Vulnerability has become a vogue term in policing during the years since 2010. In the UK, austerity measures have meant that the police have had to think carefully about how and where they focus their reducing resources. Cuts to a variety of public services have also contributed to an increase in demand for police assistance. Focusing on vulnerable people has been seen as one way of reducing this demand, which has led to a rise in research into policing vulnerability. However, the term ‘vulnerability’ has become pervasive in policing and approaches to tackling vulnerability have not been translated consistently into practice. Part of the problem has been a lack of clarity from senior police leaders and police governing bodies about what policing vulnerability means, and yet, front-line practitioner views are consistent with academic research, particularly around the issues of defining, identifying, and responding to vulnerability.

This thesis makes a unique contribution to the growing academic debate regarding the policing of vulnerable people. It uses a mixed methods approach as a means of
triangulating the research to improve consistency in its findings. This includes a focus group of police practitioners and quantitative research of 3 sets of police recorded data. The direct access to police data has allowed this thesis to research and present an original contribution to knowledge in how policing deals with vulnerability. Ultimately, this thesis argues that the concept of vulnerability in policing is an essential one. Whilst practitioners found that it was confusing, it did focus police activity to support those in need. This thesis found that police recorded data holds some significant and valuable findings about recorded vulnerability. The recording of vulnerability was inconsistent across different data sets used by the police, and this made it difficult to ascertain levels of repeat victimisation, which should be regarded as a priority vulnerability that is targeted by the police. However, analysis was able to show that vulnerability is a consistent demand across the 7-day week and is linked to routine activities theory.

To counter some of the draw backs of recorded data and staff confusion about vulnerability, this thesis has developed and presents an ecological approach to vulnerability. This model can direct police practitioners in overcoming identified flaws and improve partnership working to ensure that those with the most complex needs are in receipt of appropriate services.
Tree representations of brain structural connectivity via persistent homology

description: The brain structural connectome is generated by a collection of white matter fiber bundles constructed from diffusion weighted MRI (dMRI), acting as highways for neural activity. There has been abundant interest in studying how the structural connectome varies across individuals in relation to their traits, ranging from age and gender to neuropsychiatric outcomes. After applying tractography to dMRI to get white matter fiber bundles, a key question is how to represent the brain connectome to facilitate statistical analyses relating connectomes to traits. The current standard divides the brain into regions of interest (ROIs), and then relies on an adjacency matrix (AM) representation. Each cell in the AM is a measure of connectivity, e.g., number of fiber curves, between a pair of ROIs. Although the AM representation is intuitive, a disadvantage is the high-dimensionality due to the large number of cells in the matrix. This article proposes a simpler tree representation of the brain connectome, which is motivated by ideas in computational topology and takes topological and biological information on the cortical surface into consideration. We demonstrate that our tree representation preserves useful information and interpretability, while reducing dimensionality to improve statistical and computational efficiency. Applications to data from the Human Connectome Project (HCP) are considered and code is provided for reproducing our analyses.

description: We address the issue of BRST symmetry breaking in the GZ model, a local, renormalizable, non-perturbative approach to QCD. Explicit calculation of several examples reveals that BRST symmetry breaking apparently afflicts the unphysical sector of the theory, but may be unbroken where needed, in cases of physical interest. Specifically, the BRST-exact part of the conserved energy-momentum tensor and the BRST-exact term in the Kugo-Ojima confinement condition both have vanishing expectation value. We analyze the origin of the breaking of BRST symmetry in the GZ model, and obtain a useful sufficient condition that determines which operators preserve BRST. Observables of the GZ theory are required to be invariant under a certain group of symmetries that includes not only BRST but also others. The definition of observables is thereby sharpened, and excludes all operators known to us that break BRST invariance. We take as a hypothesis that BRST symmetry is unbroken by this class of observables. If the hypothesis holds, BRST breaking is relegated to the unphysical sector of the GZ theory, and its physical states are obtained by the usual cohomological BRST construction. The fact that the horizon condition and the Kugo-Ojima confinement criterion coincide assures that color is confined in the GZ theory.
