description: Topological superconductors should be able to provide essential ingredients for quantum computing, but are very challenging to realize. Spin-orbit interaction in iron-based superconductors opens the energy gap between the $p$-states of pnictogen and $d$-states of iron very close to the Fermi level, and such $p$-states have been recently experimentally detected. Density functional theory predicts existence of topological surface states within this gap in FeTe$_{1-x}$Se$_x$ making it an attractive candidate material. Here we use synchrotron-based angle-resolved photoemission spectroscopy and band structure calculations to demonstrate that FeTe$_{1-x}$Se$_x$ (x=0.45) is a superconducting 3D Dirac semimetal hosting type-I and type-II Dirac points and that its electronic structure remains topologically trivial. We show that the inverted band gap in FeTe$_{1-x}$Se$_x$ can possibly be realized by further increase of Te content, but strong correlations reduce it to a sub-meV size, making the experimental detection of this gap and corresponding topological surface states very challenging, not to mention exact matching with the Fermi level. On the other hand, the $p-d$ and $d-d$ interactions are responsible for the formation of extremely flat band at the Fermi level pointing to its intimate relation with the mechanism of high-T$_c$ superconductivity in IBS.

description: Relations between neutron star properties that do not depend on the nuclear equation of state offer insights on neutron star physics and have practical applications in data analysis. Such relations are obtained by fitting to a range of phenomenological or nuclear physics equation of state models, each of which may have varying degrees of accuracy. In this study we revisit commonly-used relations and re-assess them with a very flexible set of phenomenological nonparametric equation of state models that are based on Gaussian Processes. Our models correspond to two sets: equations of state which mimic hadronic models, and equations of state with rapidly changing behavior that resemble phase transitions. We quantify the accuracy of relations under both sets and discuss their applicability with respect to expected upcoming statistical uncertainties of astrophysical observations. We further propose a goodness-of-fit metric which provides an estimate for the systematic error introduced by using the relation to model a certain equation-of-state set. Overall, the nonparametric distribution is more poorly fit with existing relations, with the I-Love-Q relations retaining the highest degree of universality. Fits degrade for relations involving the tidal deformability, such as the Binary-Love and compactness-Love relations, and when introducing phase transition phenomenology. For most relations, systematic errors are comparable to current statistical uncertainties under the nonparametric equation of state distributions.

description: This dissertation is a case study focusing on how a play is developed during the production process. By breaking down the changes that took place in the six years (2007-2012) of edits in Laura Wade's Posh, one can see that a script is only finished once it begins production. The adjustments Wade made reflects the change in the British political, financial and sociological environment, which affects the scripts. This illustrates that theatre is an organic medium, and should evolve throughout the production process. Writing a complete script is just the beginning in theatre though there are classes, books and workshops one can take to write a play, the final product is not complete until it moves into production. Knowing Wade's projection as a playwright, how she writes, as well as her theatre history, one concludes that theatre is a group effort and that writing a play is only the first step in a complicated, multifaceted medium when working in the theatre.

China

description: Objective: The present study aimed to assess the psychometric properties of a Chinese version of the UPPS-P Impulsive Behavior Scale. The associations between the UPPS-P scale and impulsivity choice, gender, smoking, and drinking status were also assessed. Methods: A total of 127 adults ranging from 21 to 65 years old participated in the study. Participants were administered with the Chinese version of the UPPS-P Impulsive Behavior Scale, Beck Depression Inventory II (BDI-II), and State–Trait Anxiety Inventory (STAI). Impulsivity choice tasks were also tested including the Delay Discounting Task (DDT), Balloon Analogue Risk Task (BART), and Beads Task (Beads). Results: A new version of the UPPS-P Impulsive Behavior Scale was formed that includes 40 items. The scores of the UPPS-P Impulsive Behavior Scale demonstrated adequate internal consistency on five subscales but less sufficient structure validity in the present sample. In addition, positive urgency was negatively related to the Beads task; negative urgency and positive urgency were positively related to the DDT and BART. Moreover, positive and negative urgency were positively correlated with depression; all five subscales were positively correlated with anxiety; sensation seeking was higher in males than females and in alcohol drinkers than non-drinkers; and lack of premeditation and lack of perseverance were higher in nonsmokers than smokers. Conclusions: The present study supports the reliability but not the structure validity of the UPPS-P Impulsive Behavior Scale. The impulsivity personality trait assessed by the UPPS-P scale was associated with impulsivity choice, depression, anxiety, gender, and drinking and smoking status. Further studies should be conducted to explore the structure of impulsivity in the Chinese population.

description: This study was undertaken at Trishal upazila of Mymensingh, Bangladesh to investigate the farmers’ awareness on environmental degradation nearby the brickfield areas and to explore the relationship between the selected characteristics of the farmers (i.e. independent variables) with their awareness on environmental degradation (i.e. dependent variable). Thirty five farmers were selected randomly from a total of 175 farmers under Amiandangori village of Balipara union and thirty farmers were selected randomly from a total of 150 farmers under Dauaniabari village of Boilor union of Trishal upazila in Mymensingh district. Personal interview schedule was used for collecting data. Simple and direct questions and different scales were used to obtain desired information. Co-efficient of correlation (r) was computed in order to explore the relationships between the dependent and independent variables. The findings revealed that majority (47.70 percent) of the farmers had medium level of awareness on environmental degradation nearby the brickfield areas. Farmer’s characteristics like academic qualification, farm size, annual income, extension media contact, and knowledge on environmental degradation had significant (p <0.05) positive relationship with their awareness on environmental degradation. Besides, the findings revealed that majority (57 percent) of the respondents expressed their opinion towards medium vulnerability, 15 percent low vulnerability and 28 percent high vulnerability of environmental degradation nearby the brickfield areas.

description: AGN with the so-called `double-double' radio structure have been interpreted as restarted AGN where the inner structure is a manifestation of a new phase of activity which happened to begin before the outer radio lobes resulting from the previous one had faded completely. The radio galaxy 1245+676 is an extreme example of such a double-double object - its outer structure, measuring 970 h^{-1} kpc, is five orders of magnitude larger than the 9.6 h^{-1} pc inner one. We present a series of VLBI observations of the core of 1245+676 which appears to be a compact symmetric object (CSO). We have detected the motion of the CSO's lobes, measured its velocity, and inferred the kinematic age of that structure.

title: Quo Vadis Turkey? Turkey's State Identity Through the Ontological Security Perspective
Creators: name: Piotrowska, Natalia
Publisher: name: University of Kent
Year: 2021

description: This thesis looks at the ambivalent relationship between Turkey and the West and its impact on Turkey's state identity. It was written at the time when concerns about the West 'losing Turkey' or alternatively Turkey shifting an axis became widespread. I argue that the process of putting in doubt Turkey's position within the West started at the end of the Cold War and was initiated by the West itself. Therefore, what is now understood as a radical change is an outcome of the strategy of the West to make Turkey continuously pursue belonging without granting it due recognition. The aim of this thesis is to shift the analytical attention from 'what Turkey is for the West' or 'how it can be categorized' to account for the ways in which Turkey has responded to its changing position vis-à-vis the West after the end of bipolarity. Analytically, I build on the concept of ontological security, which overcomes the emphasis on structure and the conflation of self and identity encountered in some constructivist scholarship. I approach identity as a 'reflexive project' that requires constant attention to maintain a stable sense of self in a changing world. I put forward that stigmatization related to the status of a latecomer to the modern state system and a liminal position related to the existence of mutually exclusive discourses within this system lead to the development of a fragile sense of ontological security. Consequently, such states become extra-sensitive to concerns regarding belonging, recognition, and status, which shapes their identity and foreign policy. In three case studies, Turkey's pursuit of EU membership, the deteriorating relationship with Israel, and the decision to host Syrian refugees, I study how Turkey's quest for recognition as an equal with its Western counterparts has shaped changes within Turkey's state identity. I show that although Turkey decided to capitalize on its liminal position, which led to a more independent foreign policy and subsequent worries about Turkey's orientation, it still seeks the approval, respect, and recognition of the West.

 Remarks. This species was not studied. However, it has very characteristic coloration shown in the illustration provided in the original description. Hamilton (1980: 878) transferred the species to Agalliini and thought it probably belonged to the genus Austroagallia. The species is black with paler areas on the head and with apices of the femora and bases of the tibiae, claval veins and claval suture, red. This color combination is unique among the Oriental Agalliini. I. nigrita resembles male Japanagallia. However, the claval veins are not joined by a cross vein and hence the species is placed in the genus Igerna.

description: The multi-armed bandit (MAB) models have attracted significant research attention due to their applicability and effectiveness in various real-world scenarios such as resource allocation, online advertising, and dynamic pricing. As an important branch, the adversarial MAB problems with delayed feedback have been proposed and studied by many researchers recently where a conceptual adversary strategically selects the reward distributions associated with each arm to challenge the learning algorithm and the agent experiences a delay between taking an action and receiving the corresponding reward feedback. However, the existing models restrict the feedback to be generated from only one user, which makes models inapplicable to the prevailing scenarios of multiple users (e.g. ad recommendation for a group of users). In this paper, we consider that the delayed feedback results are from multiple users and are unrestricted on internal distribution. In contrast, the feedback delay is arbitrary and unknown to the player in advance. Also, for different users in a round, the delays in feedback have no assumption of latent correlation. Thus, we formulate an adversarial MAB problem with multi-user delayed feedback and design a modified EXP3 algorithm MUD-EXP3, which makes a decision at each round by considering the importance-weighted estimator of the received feedback from different users. On the premise of known terminal round index $T$, the number of users $M$, the number of arms $N$, and upper bound of delay $d_{max}$, we prove a regret of $\mathcal{O}(\sqrt{TM^2\ln{N}(N\mathrm{e}+4d_{max})})$. Furthermore, for the more common case of unknown $T$, an adaptive algorithm AMUD-EXP3 is proposed with a sublinear regret with respect to $T$. Finally, extensive experiments are conducted to indicate the correctness and effectiveness of our algorithms.

node locality

description: Abstract: We investigate the structure of the loss function landscape for neural networks subject to dataset mislabelling, increased training set diversity, and reduced node connectivity, using various techniques developed for energy landscape exploration. The benchmarking models are classification problems for atomic geometry optimisation and hand-written digit prediction. We consider the effect of varying the size of the atomic configuration space used to generate initial geometries and find that the number of stationary points increases rapidly with the size of the training configuration space. We introduce a measure of node locality to limit network connectivity and perturb permutational weight symmetry, and examine how this parameter affects the resulting landscapes. We find that highly-reduced systems have low capacity and exhibit landscapes with very few minima. On the other hand, small amounts of reduced connectivity can enhance network expressibility and can yield more complex landscapes. Investigating the effect of deliberate classification errors in the training data, we find that the variance in testing AUC, computed over a sample of minima, grows significantly with the training error, providing new insight into the role of the variance-bias trade-off when training under noise. Finally, we illustrate how the number of local minima for networks with two and three hidden layers, but a comparable number of variable edge weights, increases significantly with the number of layers, and as the number of training data decreases. This work helps shed further light on neural network loss landscapes and provides guidance for future work on neural network training and optimisation.

This is used to construct relative Atiyah sheaves and generalize Atiyah's and Tu's results about semistable sheaves over elliptic curves to the case of elliptic fibrations. Moreover we show that this transform preserves relative (semi)stability of sheaves of positive relative degree.

description: The photovoltaic (PV) industry is seeing a significant shift toward large-scale solar plants, where traditional inspection methods have proven to be time-consuming and costly. Currently, the predominant approach to PV inspection using unmanned aerial vehicles (UAVs) is based on photogrammetry. However, the photogrammetry approach presents limitations, such as an increased amount of useless data during flights, potential issues related to image resolution, and the detection process during high-altitude flights. In this work, we develop a visual servoing control system applied to a UAV with dynamic compensation using a nonlinear model predictive control (NMPC) capable of accurately tracking the middle of the underlying PV array at different frontal velocities and height constraints, ensuring the acquisition of detailed images during low-altitude flights. The visual servoing controller is based on the extraction of features using RGB-D images and the Kalman filter to estimate the edges of the PV arrays. Furthermore, this work demonstrates the proposal in both simulated and real-world environments using the commercial aerial vehicle (DJI Matrice 100), with the purpose of showcasing the results of the architecture. Our approach is available for the scientific community in: https://github.com/EPVelasco/VisualServoing_NMPC

DLPFC (dorsolateral prefrontal cortex)

description: Objectives: Transcranial magnetic stimulation (TMS) holds potential promise as a therapeutic modality for disorders of addiction. Our previous findings indicate that high-frequency repetitive transcranial magnetic stimulation (rTMS) over the left dorsal–lateral prefrontal cortex (DLPFC) and low-frequency rTMS over the right DLPFC can reduce drug craving for methamphetamine. One major issue with rTMS is the duration of treatment and hence potential dropout rate. Theta burst stimulation (TBS) has been recently shown to be non-inferior relative to repetitive transcranial magnetic stimulation for major depression. Here, we aim to compare the clinical efficacy and tolerability of intermittent and continuous theta burst stimulation protocols targeting left or right dorsolateral prefrontal cortex on methamphetamine craving in abstinent-dependent subjects. Methods: In this randomized single-blind pilot study, 83 abstinent methamphetamine-dependent subjects from a long-term residential treatment program were randomly allocated into three groups: intermittent theta burst stimulation (iTBS) over the left DLPFC (active group), continuous theta burst stimulation (cTBS) over the left DLPFC (active control group), or cTBS over the right DLPFC (active group) was administered twice daily over 5 days for a total of 10 sessions. We measured the primary outcome of cue-induced craving and secondarily sleep quality, depression, anxiety, impulsivity scores, and adverse effects. Results: We show a pre- vs. postintervention effect on craving, which, on paired t tests, showed that the effect was driven by iTBS of the left DLPFC and cTBS of the right DLPFC, reducing cue-induced craving but not cTBS of the left DLPFC. We did not show the critical group-by-time interaction. The secondary outcomes of depression, anxiety, and sleep were unrelated to the improvement in craving in the left iTBS and right cTBS group. In the first two sessions, self-reported adverse effects were higher with left iTBS when compared to right cTBS. The distribution of craving change suggested greater clinical response (50% improvement) with right cTBS and a bimodal pattern of effect with left iTBS, suggesting high interindividual variable response in the latter. Conclusion: Accelerated twice-daily TBS appears feasible and tolerable at modulating craving and mood changes in abstinent methamphetamine dependence critically while reducing session length. We emphasize the need for a larger randomized controlled trial study with a sham control to confirm these findings and longer duration of clinically relevant follow-up.

description: This work has been motivated by recent papers that quantify the density of values of generic quadratic forms and other polynomials at integer points, in particular ones that use Rogers' second moment estimates. In this paper we establish such results in a very general framework. Given any subhomogeneous function (a notion to be defined) $f: \mathbb{R}^n \to \mathbb{R}$, we derive a necessary and sufficient condition on the approximating function $ψ$ for guaranteeing that a generic element $f\circ g$ in the $G$-orbit of $f$ is $ψ$-approximable; that is, $|f\circ g(\mathbf{v})| \le ψ(\|\mathbf{v}\|)$ for infinitely many $\mathbf{v} \in \mathbb{Z}^n$. We also deduce a sufficient condition in the case of uniform approximation. Here, $G$ can be any closed subgroup of $\rm{ASL}_n(\mathbb{R})$ satisfying certain axioms that allow for the use of Rogers-type estimates.

title: Party Competition in Post-devolution Scotland
Creators: name: Wright, Kieran
Publisher: name: University of Kent
Year: 2021

description: This thesis investigates the tactical choices political parties make in multi-level settings where a significant regional nationalist party operates. It presents an original account of the strategic options available to parties in that type of setting and then applies that framework to the case study of post-devolution Scotland. It argues that rhetorical strategy constitutes a distinct element in the tactical armoury available to political parties alongside the manipulation of policy position and issue salience. It also puts forward the idea that in circumstances where party competition takes place along a centre-periphery axis of competition alongside the ubiquitous left right one there exist two types of subsuming strategy where party spokespeople justify their party's position on one axis of competition by referencing its position on the other. It argues that there exists a positive subsuming strategy in which the position referenced on both axes is in line with the party's established policy identity and a negative subsuming strategy where one of the positions referenced is at variance with that established identity.It applies this framework via a mixed method analysis of the language used by representatives of the main Scottish parties in sessions of First Ministers Question Time in the Scottish Parliament. In doing so it shows that changes in incumbency position at state-wide and devolved level within the multi-level setting can significantly impact upon the tactical choices political parties make. Similarly whether the next scheduled electoral contest is for the devolved or state-wide tier of government is also shown to have a significant effect.The results of the analysis also demonstrate that the rhetorical justification political actors employ for their policy preferences represents a distinct element in party strategy. It presents evidence to show that this aspect of party strategy can be manipulated separately from policy position and issue salience, and that it can have a significant impact upon public perception regarding the ideological orientation of political parties. This finding extends existing scholarly understanding of how voters make judgements about political parties suggesting that they can respond to changes in rhetorical strategy by revising their judgment regarding to where political parties stand relative to their opponents.

description: As the exorbitant expense of labeling autopilot datasets and the growing trend of utilizing unlabeled data, semi-supervised segmentation on point clouds becomes increasingly imperative. Intuitively, finding out more ``unspoken words'' (i.e., latent instance information) beyond the label itself should be helpful to improve performance. In this paper, we discover two types of latent labels behind the displayed label embedded in LiDAR and image data. First, in the LiDAR Branch, we propose a novel augmentation, Cylinder-Mix, which is able to augment more yet reliable samples for training. Second, in the Image Branch, we propose the Instance Position-scale Learning (IPSL) Module to learn and fuse the information of instance position and scale, which is from a 2D pre-trained detector and a type of latent label obtained from 3D to 2D projection. Finally, the two latent labels are embedded into the multi-modal panoptic segmentation network. The ablation of the IPSL module demonstrates its robust adaptability, and the experiments evaluated on SemanticKITTI and nuScenes demonstrate that our model outperforms the state-of-the-art method, LaserMix.

description: The current should be proportional to the momentum in a Galilean-invariant system of particles of fixed charge-to-mass ratio, such as an electron liquid in jellium. However, strongly-interacting electron systems can have phases characterized by broken symmetry or fractionalization. Such phases can have neutral excitations which can presumably carry momentum but not current. In this paper, we show that there is no contradiction: `neutral' excitations {\em do} carry current in a Galilean-invariant system of particles of fixed charge-to-mass ratio. This is explicitly demonstrated in the context of spin waves, the Bogoliubov-de Gennes quasiparticles of a superconductor, the one-dimensional electron gas, and spin-charge separated systems in 2+1 dimensions. We discuss the implications for more realistic systems, which are not Galilean-invariant.

description: Internal snapping of the psoas tendon is a frequently reported condition, especially in young adolescents involved in sports. It is defined as an increased tendon excursion over bony or soft tissue prominence causing local irritation and inflammation of the tendon leading to groin pain and often is accompanied by an audible snap. Due to the lack of detailed dynamic visualization means, the exact mechanism of the condition remains poorly understood and different theories have been postulated related to the etiology and its location about the hip. In the present study we simulated psoas tendon behavior in a virtual population of 40,000 anatomies and compared tendon movement during combined abduction, flexion and external rotation and back to neutral extension and adduction. At risk phenotyopes for tendon snapping were defined as the morphologies presenting with excess tendon movement. There were little differences in tendon movement between the male and female models. In both populations, abnormal tendon excursion correlated with changes in mainly the femoral anatomy (male r = 0.72, p < 0.001, female r = 0.66, p < 0.001): increased anteversion and valgus as well as a decreasing femoral offset and ischiofemoral distance. The observed combination of shape components correlating with excess tendon movement in essence presented with a medial positioning of the minor trochanter. This finding suggest that psoas snapping and ischiofemoral impingement are possibly two presentations of a similar underlying rotational dysplasia of the femur.

description: This thesis concerns itself with the extension theory of second-order difference equations in both a linear operator and linear relation framework. In Chapter 1, we introduce the extension theory of linear operators by means of both the von Neumann and the Krein-Vishik-Birman method. Chapter 2 is devoted to the construction of the non-negative, self-adjoint extensions of a particular class of second-order difference operators via the Krein-Vishik-Birman theory, with particular emphasis on the Friedrichs extension. We determine an explicit characterisation of such extensions, before applying this result to a second-order difference equation whose solutions are the Stieltjes-Wigert polynomials.Linear relations and their extensions are introduced in Chapter 3. In particular, a construction of the extremal maximal sectorial relations by Hassi et al. is considered. These results are utilised in Chapter 4 when we construct the extremal maximal sectorial extensions of the Discrete Laplacian with both the standard domain of square summable sequences and the sequences in that space with first component equal to 0.

Self-gravitating planetary envelopes and the core-nucleated instability

description: Planet formation scenarios can be constrained by the ratio of the gaseous envelope mass relative to the solid core mass in the observed exoplanet populations. One-dimensional calculations find a critical (maximal) core mass for quasi-static envelopes to exist, suggesting that envelopes around more massive cores should collapse due to a `core-nucleated' instability. We study self-gravitating planetary envelopes via hydrodynamic simulations, progressively increasing the dimensionality of the problem. We characterize the core-nucleated instability and its non-linear evolution into runaway gas accretion in one-dimensional spherical envelopes. We show that rotationally-supported envelopes can enter a runaway accretion regime via polar shocks in a two-dimensional axisymmetric model. This picture remains valid for high-mass cores in three dimensions, where the gas gravity mainly adds up to the core gravity and enhances the mass accretion rate of the planet in time. We relate the core-nucleated instability to the absence of equilibrium connecting the planet to its parent disk and discuss its relevance for massive planet formation.

description: Additional file 4: Figure S2. Description of the integrated screening device. Droplets were loaded (inlet b) and spaced by two streams of fluorinated oil containing surfactant (inlet a). The relevant enzymatic substrate (inlet c) was injected into each droplet by applying an AC field (20kHz, 200 V pp ). The droplet contents were then mixed and the oil was extracted to increase the packing degree of the emulsion (inlet d, panel 2). Droplets were then incubated along the delay line and again spaced with two streams of fluorinated oil (inlets e) before entering the sorting module. The fluorescence of each droplet was measured. By default, the droplets flowed in the channel with the lower hydrodynamic resistance (outlet f). Droplets could be sorted based fluorescence intensity by applying AC field pulses (30 kHz; 1200 V pp ; 0.3-0.6 ms) and collected (outlet g).

description: Histological atlases of the cerebral cortex, such as those made famous by Brodmann and von Economo, are invaluable for understanding human brain microstructure and its relationship with functional organization in the brain. However, these existing atlases are limited to small numbers of manually annotated samples from a single cerebral hemisphere, measured from 2D histological sections. We present the first whole-brain quantitative 3D laminar atlas of the human cerebral cortex. It was derived from a 3D histological atlas of the human brain at 20-micrometer isotropic resolution (BigBrain), using a convolutional neural network to segment, automatically, the cortical layers in both hemispheres. Our approach overcomes many of the historical challenges with measurement of histological thickness in 2D, and the resultant laminar atlas provides an unprecedented level of precision and detail. We utilized this BigBrain cortical atlas to test whether previously reported thickness gradients, as measured by MRI in sensory and motor processing cortices, were present in a histological atlas of cortical thickness and which cortical layers were contributing to these gradients. Cortical thickness increased across sensory processing hierarchies, primarily driven by layers III, V, and VI. In contrast, motor-frontal cortices showed the opposite pattern, with decreases in total and pyramidal layer thickness from motor to frontal association cortices. These findings illustrate how this laminar atlas will provide a link between single-neuron morphology, mesoscale cortical layering, macroscopic cortical thickness, and, ultimately, functional neuroanatomy.
