description: The equilibrium distribution function of a relativistic ideal gas has been derived to include the effect of angular momentum. The result agrees with the one obtained from kinetic theory, and consistent with relativistic thermodynamics. The role of angular momentum becomes transparent in this derivation, and the equilibrium distribution can be generalized to accommodate the effect of intrinsic angular momentum. The results here is for a flat spacetime, however, same approach can be applied to static curved spacetimes.

description: Reputations are an essential feature of human sociality and the evolution of cooperation and group living. Much scholarship has focused on reputations, yet typically on a narrow range of domains (e.g. prosociality and aggressiveness), usually in isolation. Humans can develop reputations, however, from any collective information. We conducted exploratory analyses on the content, distribution and structure of reputation domain diversity across cultures, using the Human Relations Area Files ethnographic database. After coding ethnographic texts on reputations from 153 cultures, we used hierarchical modelling, cluster analysis and text analysis to provide an empirical view of reputation domains across societies. Findings suggest (i) reputational domains vary cross-culturally, yet reputations for cultural conformity, prosociality, social status and neural capital are widespread; (ii) reputation domains are more variable for males than females and (iii) particular reputation domains are interrelated, demonstrating a structure consistent with dimensions of human uniqueness. We label these features: Cultural group unity, Dominance, Neural capital, Sexuality, Social and material success and Supernatural healing. We highlight the need for future research on the evolution of cooperation and human sociality to consider a wider range of reputation domains, as well as their social, ecological and gender-specific variability.This article is part of the theme issue ‘The language of cooperation: reputation and honest signalling’.

description: We report an unusual evolution of structure and magnetism in stoichiometric MnO clusters based on an extensive and unbiased search through the potential energy surface within density functional theory. The smaller clusters, containing up to five MnO units, adopt two-dimensional structures; and regardless of the size of the cluster, magnetic coupling is found to be antiferromagnetic in contrast to previous theoretical findings. Predicted structure and magnetism are strikingly different from the magnetic core of Mn-based molecular magnets, whereas they were previously argued to be similar. Both of these features are explained through the inherent electronic structures of the clusters.

description: I sampled terrestrial arthropods in burned salvaged-logged, burned-unlogged and unburned conifer forest sites in southwestern Alberta. The richness, diversity and abundance of ground beetle (Coleoptera: Carabidae) species and genera, and spider (Araneae) and syrphid genera (Diptera: Syrphidae) were examined. Carabid richness and diversity was highest in the burned-unsalvaged site. However, abundance was similar among the sites. Carabids common to the burned areas included, Trachypachus, Sericoda, Harpalus and Amara species. Overall, yellow pans caught more carabid species and specimens with less sampling than pitfall traps. Spider richness and abundance were greatest in the unburned site. Pardosa predominated across all three sites and the number of web-building genera and specimens were highest in the unburned site. Syrphid richness and abundance were similar across the sites. Richness and abundance declined over the summer with peak capture rates in May-June.

description: Entanglement entropy has become an important theoretical concept in condensed matter physics, because it provides a unique tool for characterizing quantum mechanical many-body phases and new kinds of quantum order. However, the experimental measurement of entanglement entropy in a many-body systems is widely believed to be unfeasible, owing to the nonlocal character of this quantity. Here, we propose a general method to measure the entanglement entropy. The method is based on a quantum switch (a two-level system) coupled to a composite system consisting of several copies of the original many-body system. The state of the switch controls how different parts of the composite system connect to each other. We show that, by studying the dynamics of the quantum switch only, the Renyi entanglement entropy of the many-body system can be extracted. We propose a possible design of the quantum switch, which can be realized in cold atomic systems. Our work provides a route towards testing the scaling of entanglement in critical systems, as well as a method for a direct experimental detection of topological order.

description: Temperature evolution of the ferromagnetic resonance (FMR) and its interference with other microwave (MW) magnons near the collinear to conical ferrimagnetic phase transition at Tc2 = 305 K is found to correlate with the evolution of the weak-field magnetization: from two components in the conical phase to one component in the collinear phase. The FMR splitting above Tc2 correlates with the splitting of the coercive fields of the two magnetization components. A high sensitivity of the FMR to the weak magnetic bias near Tc2 is shown to be caused by the gradual transformation of the conical spin magnetic moments to the longitudinal ones. Application of the weak magnetic bias allows to adjust the MW absorption, and its level of above 30 dB is achieved near the FMR frequency (5.7 - 7.2 GHz), that allows to consider the Sr4CoZnFe36O60 hexaferrite ceramics as a possible MW absorbing material.

description: Bell non-locality stems from quantum correlations effectively identified using inequalities. Spin chains, simulated with ultra-cold atoms in optical lattices, Rydberg atoms in tweezer arrays, trapped ions, or molecules, allow single-spin control and measurement. Therefore, they are suitable for studying fundamental aspects of these correlations and non-locality. Occupation defects, such as vacancies or multiple atoms occupying a single site due to imperfect system preparation, limit the detection of Bell correlations. We study their effects with the help of a simplified toy model parameterised by the probability $p$ of having a single occupation for a given site. Within this model, and for entangled systems obtained by one-axis twisting evolution from an initial factorised state, we derive two Bell inequalities, one based on many-site correlations and the other on two-site correlations, and identify the smallest probability $p$ that allows the Bell inequalities violation to be detected. We then consider two physical realizations using entangled ultra-cold atoms in optical lattices where the parameter $p$ is related to a non-unitary filling factor and non-zero temperature. We test the predictions of the toy model against exact numerical results.

Creators: name: Ryecroft, SP
Publisher: name: Liverpool John Moores University
Year: 2024

description: Water is essential to our daily lives, we consume water in many ways, from drinking it to washing and bathing ourselves. In many developed countries such as the United Kingdom however these standards are ensured by water suppliers who processes and treat water before it enters the drinking water supply. This process involves the monitoring of water catchment areas used by treatment works which is currently monitored through manual methods only enabling the monitoring of small areas of large catchment areas. This thesis presents work that could enable the remote real time monitoring of water catchment sites. This thesis presents work showing the impact of conductivity on radio frequency communication distances and showing real world communication distances in the Leeds Liverpool canal of up to 7 meters at data rates of 1.2 kbps The real world experiments showed that lower baud rates could achieved larger communication distances, with further work undertaken at a water catchment site where communication distances of 17 meters at data rates of 1.2 kbps achieved with direct communication and showing data transmission across the air water boundary. This thesis also explores the development of microwave sensors for the detection of Geosmin and Alphacypermethrin in water samples, both of which are common contaminates within water catchment areas. This thesis applies machine learning to microwave data sets to identify frequencies sensitive to contaminates at levels as low as 5 ng/l for Geosmin and 25mg/m2 for Alphacypermethrin, enabling the future development of a microwave sensor targeted at the detection of these contaminates.

description: To improve the adherence of future R&I activities, Ben@Rail shall develop a framework based on a stakeholder analysis and technological inputs. To achieve the final goal of assessing the benefits of the stakeholders from future R&I activities, the technological inputs will in the final stage be compared and weighted against the stakeholder requirements. This will allow to verify the research priorities within the upcoming Europe’s Rail Joint Undertaking (ERJU).
 This document provides a structured overview of the R&I objectives given by the research plans published by the European Rail Research Advisory Council (ERRAC) and the ERJU, and with this delivers the technical inputs for the comparison with the stakeholder requirements defined in Deliverable D1.1 “Simplified stakeholder tree and weighting matrix of requirements”. The objectives have been extracted from different documents, with a main focus on the “Europe’s Rail Joint Undertaking Master Plan” (MP) and the “Europe’s Rail Joint Undertaking Multi-Annual Work Programme” (MAWP). Additonal documents, published by other Shift2Rail research projects, like TER4RAIL and Mobility4EU, or representatives of other transport sectors, have been examined as well.
title: The Application of EnerPHit Standard to Residential Tower Blocks in the UK
Creators: name: Hirbod, Soha
Publisher: name: University of Kent
Year: 2018

description: This study examines the refurbishment of residential tower blocks in the UK according to the EnerPHit standard, which is an adaptation of the Passivhaus standard for retrofit. Currently, no single high-rise building in the UK has achieved this standard. The research focuses on the case study of Wilmcote House, a social housing tower block in Portsmouth owned and managed by Portsmouth City council. Wilmcote House is the first UK tower block being refurbished using the EnerPHit standard. Nevertheless, the building will not fully achieve EnerPHit by the time of project completion due to a lack of compliance with the primary energy demand. The Wilmcote House case study involves an investigation of the project process from the tender early stages to the delivery of the building. Research methods such as interviewing the project team members, direct observations of the project proceedings on site, attending site meetings, and archival research into the design process have led to important insights into the challenges of the pioneering real-life project. The study also investigates the refurbishment project of [REDACTED]and [REDACTED], two other social housing tower blocks in [REDACTED], to make cross-case comparisons. [REDACTED]appointed the same architects to propose a design for the refurbishment of the blocks based on EnerPHit, but they decided not to proceed with the project following the feasibility stage. The rare opportunity of the author to work with the architects at the initial stages of the [REDACTED]and [REDACTED]projects and to carry out embedded research has provided a critical understanding of the project complications. Based on the case studies, the research aims to uncover the specific requirements and difficulties related to the process of applying EnerPHit to UK tower blocks. The study also examines possible solutions to overcoming the challenges encountered at different stages of the process. The research reveals that the approach of the client and the architects towards the tower block refurbishment are two determining factors in adopting EnerPHit; the physical properties of tower blocks can create difficulties with meeting EnerPHit criteria such as primary energy demand, and the requirement for EnerPHit training and lack of sufficient communication between the teams can seriously complicate the construction stage.
Short Gamma-ray Bursts: the mass of the accretion disk and the initial radius of the outflow

description: In this work we estimate the accretion-disk mass in the specific scenario of binary-neutron-star-merger with current observational data. Assuming that the outflows of short Gamma-ray Bursts (GRBs) are driven via neutrino-antineutrino annihilation we estimate the disk mass of about half of short bursts in the sample to be $\sim 0.01-0.1 M_\odot$, in agreement with that obtained in the numerical simulations. Massive disks ($\sim {\rm several} 0.1 M_\odot$) found in some other short GRBs may point to the more efficient magnetic process of energy extraction or the neutron star and black hole binary progenitor. Our results suggest that some short bursts may be really due to the coalescence of double neutron stars and are promising gravitational wave radiation sources. For future short GRBs with simultaneous gravitational-wave detections, the disk mass may be reliably inferred and the validity of our approach will be tested. We also propose a method to constrain the initial radius of a baryonic outflow where it is launched ($R_0$) without the need of identifying an ideal thermal spectrum. We then apply it to GRB 090510 and get that $R_0 \lesssim 6.5\times 10^{6}(Γ_{\rm ph}/2000)^{-4}$ cm, suggesting that the central engine is a black hole with a mass $< 22 M_\odot(Γ_{\rm ph}/2000)^{-4}$, where $Γ_{\rm ph}$ is the bulk Lorentz factor of the outflow at the photospheric radius.

description: We briefly discuss models of energetic particle acceleration by supernova shock in active starforming regions at different stages of their evolution. Strong shocks may strongly amplify magnetic fields due to cosmic ray driven instabilities. We discuss the magnetic field amplification emphasizing the role of the long-wavelength instabilities. Supernova shock propagating in the vicinity of a powerful stellar wind in a young stellar cluster is argued to increase the maximal CR energies at a given evolution stage of supernova remnant (SNR) and can convert a sizeable fraction of the kinetic energy release into energetic particles.

Adoption and attachment: a study of attachment in young adult adoptees

Publisher: name: University of Calgary
Year: 2003

description: Bibliography: p. 87-97
description: Extrapolating from the central tenets of attachment theory and research, the present study investigated the implications for the adoption experience on the developing security and pattern of attachment relationships. Differences between adoptee and non-adoptee attachment classifications were explored, and classification differences were analyzed based on their relationship with demographic and theoretically relevant variables. A sample of 34 late adolescent to young-adult adoptee volunteers (20 females, 14 males), ranging from 17 to 32 years of age, were recruited. They were administered the Adult Attachment Interview, the Adult Attachment Projective, and asked questions relating to their adoptions. The sample's distribution of Adult Attachment Projective classifications was compared to norms of community and clinical samples. Consistent with the implications from attachment theory and research, the adoptee distribution differed significantly from that expected for a non-adopted, non-clinical sample (p:S.0001). Furthermore, several features of the distribution pattern were also consistent with projections from attachment theory and research. First, the rate of secure or Autonomous attachment is significantly lower than expected (E) (15%, E = 52%). Second, Dismissing attachment, the most common form of insecurity in normative samples, is nearly absent in this sample (6%, E = 18%). Third, both the Preoccupied (47%, E = 11 %) and the atypical Unresolved/Disorganized (32%, E = 19%) attachment classifications are overrepresented in this sample relative to the comparison norms. These adoptees resembled a clinical sample in their distribution of attachment patterns. Between classification group differences were analyzed by examining their relationship with the following variables: age, gender, age at adoption, professional status, relationship status, parenting status, search for birth family/outcome, counseling experience, and subsequent threats to attachm~nt (loss, trauma, abuse, rejection, and separation). None of these analyses supported an association between any of the independent variables and classification group differences. The findings from this study support the theory that adoptees are at greater risk for insecure attachments than their non-adopted counterparts. It is recommended that future studies make further attempts to identify the source/s of these differences.
Real-time operator evolution in two and three dimensions via sparse Pauli dynamics

Year: 2024

description: We study real-time operator evolution using sparse Pauli dynamics, a recently developed method for simulating expectation values of quantum circuits. On the examples of energy and charge diffusion in 1D spin chains and sudden quench dynamics in the 2D transverse-field Ising model, it is shown that this approach can compete with state-of-the-art tensor network methods. We further demonstrate the flexibility of the approach by studying quench dynamics in the 3D transverse-field Ising model which is highly challenging for tensor network methods. For the simulation of expectation value dynamics starting in a computational basis state, we introduce an extension of sparse Pauli dynamics that truncates the growing sum of Pauli operators by discarding terms with a large number of X and Y matrices. This is validated by our 2D and 3D simulations. Finally, we argue that sparse Pauli dynamics is not only capable of converging challenging observables to high accuracy, but can also serve as a reliable approximate approach even when given only limited computational resources.

description: Background: The delineation of genomic copy number abnormalities (CNAs) from cancer samples has been instrumental for identification of tumor suppressor genes and oncogenes and proven useful for clinical marker detection. An increasing number of projects have mapped CNAs using high-resolution microarray based techniques. So far, no single resource does provide a global collection of readily accessible oncoge- nomic array data. Methodology/Principal Findings: We here present arrayMap, a curated reference database and bioinformatics resource targeting copy number profiling data in human cancer. The arrayMap database provides a platform for meta-analysis and systems level data integration of high-resolution oncogenomic CNA data. To date, the resource incorporates more than 40,000 arrays in 224 cancer types extracted from several resources, including the NCBI's Gene Expression Omnibus (GEO), EBIs ArrayExpress (AE), The Cancer Genome Atlas (TCGA), publication supplements and direct submissions. For the majority of the included datasets, probe level and integrated visualization facilitate gene level and genome wide data re- view. Results from multi-case selections can be connected to downstream data analysis and visualization tools. Conclusions/Significance: To our knowledge, currently no data source provides an extensive collection of high resolution oncogenomic CNA data which readily could be used for genomic feature mining, across a representative range of cancer entities. arrayMap represents our effort for providing a long term platform for oncogenomic CNA data independent of specific platform considerations or specific project dependence.

Optimal Control Realizations of Lagrangian Systems with Symmetry

description: A new relation among a class of optimal control systems and Lagrangian systems with symmetry is discussed. It will be shown that a family of solutions of optimal control systems whose control equation are obtained by means of a group action are in correspondence with the solutions of a mechanical Lagrangian system with symmetry. This result also explains the equivalence of the class of Lagrangian systems with symmetry and optimal control problems discussed in \cite{Bl98}, \cite{Bl00}. The explicit realization of this correspondence is obtained by a judicious use of Clebsch variables and Lin constraints, a technique originally developed to provide simple realizations of Lagrangian systems with symmetry. It is noteworthy to point out that this correspondence exchanges the role of state and control variables for control systems with the configuration and Clebsch variables for the corresponding Lagrangian system. These results are illustrated with various simple applications.

description: The numerical simulation and optimization of technical systems described by partial differential equations is expensive, especially in multi-query scenarios in which the underlying equations have to be solved for different parameters. A comparatively new approach in this context is to combine the good approximation properties of neural networks (for parameter dependence) with the classical finite element method (for discretization). However, instead of considering the solution mapping of the PDE from the parameter space into the FEM-discretized solution space as a purely data-driven regression problem, so-called physically informed regression problems have proven to be useful. In these, the equation residual is minimized during the training of the neural network, i.e., the neural network "learns" the physics underlying the problem. In this paper, we extend this approach to saddle-point and non-linear fluid dynamics problems, respectively, namely stationary Stokes and stationary Navier-Stokes equations. In particular, we propose a modification of the existing approach: Instead of minimizing the plain vanilla equation residual during training, we minimize the equation residual modified by a preconditioner. By analogy with the linear case, this also improves the condition in the present non-linear case. Our numerical examples demonstrate that this approach significantly reduces the training effort and greatly increases accuracy and generalizability. Finally, we show the application of the resulting parameterized model to a related inverse problem.

description: We construct a relativistic scattering theory based on a q deformation and large string tension limit of the magnon S-matrix of the string world sheet theory in AdS_5 x S^5. The S-matrix falls naturally into a previously studied class associated to affine quantum groups, in this case for a twisted affine loop superalgebra associated to an outer automorphism of sl(2|2). This infinite algebra includes the celebrated triply extended psl(2|2) x R^3 algebra, but only two of the centres, the lightcone components of the 2-momentum, are non-vanishing. The algebra has the interpretation as an extended supersymmetry algebra including a non-trivial R-symmetry. The representation theory of this algebra has some complications in that tensor products are reducible but indecomposable, however, we find that structure meshes perfectly with the bootstrap, or fusion, equations of S-matrix theory. The bootstrap equations can then be used inductively to generate the complete S-matrix. Unlike the magnon theory, the relativistic theory only has a finite set of states and we find that - at least when the deformation parameter q is a root of unity - the spectrum matches precisely the soliton spectrum of the relativistic theory underlying the Pohlmeyer reduction of the string world sheet theory known as the semi-symmetric space sine-Gordon theory.

description: If a Tychonoff space $X$ is dense in a Tychonoff space $Y$, then $Y$ is called a Tychonoff extension of $X$. Two Tychonoff extensions $Y_1$ and $Y_2$ of $X$ are said to be equivalent, if there exists a homeomorphism $f:Y_1\rightarrow Y_2$ which keeps $X$ pointwise fixed. This defines an equivalence relation on the class of all Tychonoff extensions of $X$. We identify those extensions of $X$ which belong to the same equivalence classes. For two Tychonoff extensions $Y_1$ and $Y_2$ of $X$, we write $Y_2\leq Y_1$, if there exists a continuous function $f:Y_1\rightarrow Y_2$ which keeps $X$ pointwise fixed. This is a partial order on the set of all Tychonoff extensions of $X$. If a Tychonoff extension $Y$ of $X$ is such that $Y\backslash X$ is a singleton, then $Y$ is called a one-point extension of $X$. Let $T(X)$ denote the set of all one-point extensions of $X$. We study the order structure of the partially ordered set $(T(X),\leq)$. For a locally compact space $X$, we define an order-anti-isomorphism from $T(X)$ onto the set of all non-empty closed subsets of $βX\backslash X$. We consider various sets of one-point extensions, including the set of all one-point locally compact extensions of $X$, the set of all one-point Lindelof extensions of $X$, the set of all one-point pseudocompact extensions of $X$, and the set of all one-point Cech-complete extensions of $X$, among others. We study how these sets of one-point extensions are related, and investigate the relation between their order structure, and the topology of subspaces of $βX\backslash X$. We find some lower bounds for cardinalities of some of these sets of one-point extensions, and in a concluding section, we show how some of our results may be applied to obtain relations between the order structure of certain subfamilies of ideals of $C^*(X)$ and the topology of subspaces of $βX\backslash X$.

The self-propelled Brownian spinning top: dynamics of a biaxial swimmer at low Reynolds numbers

description: Recently, the Brownian dynamics of self-propelled (active) rod-like particles was explored to model the motion of colloidal microswimmers, catalytically-driven nanorods, and bacteria. Here, we generalize this description to biaxial particles with arbitrary shape and derive the corresponding Langevin equation for a self-propelled Brownian spinning top. The biaxial swimmer is exposed to a hydrodynamic Stokes friction force at low Reynolds numbers, to fluctuating random forces and torques as well as to an external and an internal (effective) force and torque. The latter quantities control its self-propulsion. Due to biaxiality and hydrodynamic translational-rotational coupling, the Langevin equation can only be solved numerically. In the special case of an orthotropic particle in the absence of external forces and torques, the noise-free (zero-temperature) trajectory is analytically found to be a circular helix. This trajectory is confirmed numerically to be more complex in the general case involving a transient irregular motion before ending up in a simple periodic motion. By contrast, if the external force vanishes, no transient regime is found and the particle moves on a superhelical trajectory. For orthotropic particles, the noise-averaged trajectory is a generalized concho-spiral. We furthermore study the reduction of the model to two spatial dimensions and classify the noise-free trajectories completely finding circles, straight lines with and without transients, as well as cycloids and arbitrary periodic trajectories.

title: Portfolio of Doctorate in Health Psychology: A window on the workings of a hospital-based trainee health psychologist.
Creators: name: McCrossan, T
Publisher: name: Liverpool John Moores University
Year: 2022

description: This portfolio details work completed for the purpose of fulfilling the five competencies that form the Professional Doctorate in Health Psychology. Professional practice. At the start of training, the trainee worked as a Trainee Health Psychologist within one NHS trust. The professional competence was fulfilled throughout training by working in accordance with the BPS/HCPC guidelines and codes of conduct. A copy of the trainee’s log of training, signed by the trainee’s supervisor, is included in this portfolio alongside the reflective commentary. Research: A systematic review was undertaken, exploring the potential of psychological interventions to impact self-management in adults with type 2 diabetes(T2DM). Research paper one, a research paper was completed outlining the potential barriers to behaviour change implementation in a specialist diabetes team. Research paper two is a case study exploring the use of hypnotherapy in addressing needle phobia in type II diabetes. Behaviour Change Intervention (BCI): the case studies submitted for the fulfilment of this competence involved taking an in-depth look at a one-to-one session with an individual with diabetes and issues around medication adherence, as well as a group intervention in pain management. Consultancy: External links were made for the purpose of consultancy which sought to assess and evaluate the potential benefit that engaging in crafts could provide for general health and wellbeing in the local community. This is an area of personal interest. The resulting case study explored the potential well-being effects of engaging in crafting. Teaching and Training; Additionally, external links were developed with an external agency for the purpose of consultancy. A training series was developed ‘Psycho-neuro-immunology in Health Psychology’ to NHS health staff for the teaching and training competence. Reflective commentary: The portfolio ends with an in-depth reflective account of experience of training, exploring the highs and lows of working in a hospital- based health psychology department while pursuing the Professional Doctorate in Health Psychology.
Context Protecting Privacy Preservation in Ubiquitous Computing

description: In ubiquitous computing domain context awareness is an important issue. So, in ubiquitous computing, mere protection of message confidentiality is not sufficient for most of the applications where context-awareness can lead to near deterministic ideas. An adversary might deduce sensitive information by observing the contextual data, which when correlated with prior information about the people and the physical locations that are being monitored by a set of sensors can reveal most of the sensitive information. So, it is obvious that for security and privacy preservation in ubiquitous computing context protection is of equal importance. In this paper, we propose a scheme which provides two layer privacy protection of user's or application's context data. Our proposed context protecting privacy preservation scheme focuses on protecting spatial and temporal contextual information. We consider the communication part of ubiquitous computing consists of tiny sensor nodes forming Wireless Sensor Networks (WSNs). Through simulation we show the efficacy of our scheme. We also demonstrate the capability of our scheme to overcome the constraints of WSNs.
