description: The effect of age at injury on outcome after acquired brain injury (ABI) has been the subject of much debate. Many argue that young brains are relatively tolerant of injury. A contrasting viewpoint due to Hebb argues that greater system integrity may be required for the initial establishment of a function than for preservation of an already-established function. A neuro-computational model of cortical map formation was adapted to examine effects of focal and distributed injury at various stages of development. This neural network model requires a period of training during which it self-organizes to establish cortical maps. Injuries were simulated by lesioning the model at various stages of this process and network function was monitored as "development" progressed to completion. Lesion effects are greater for larger, earlier, and distributed (multifocal) lesions. The mature system is relatively robust, particularly to focal injury. Activities in recovering systems injured at an early stage show changes that emerge after an asymptomatic interval. Early injuries cause qualitative changes in system behavior that emerge after a delay during which the effects of the injury are latent. Functions that are incompletely established at the time of injury may be vulnerable particularly to multifocal injury.
title: A material-led investigation into the creative potential of British 'waste' wools for fine craft felt-making
Creators: name: Clay, E.S
Publisher: name: Bath Spa University
Year: 2013

description: This thesis describes the practical investigation and analysis of traditional materials and processes used in the production of hand made felt. Specifically, the research examines the potential of certain British wool types that are currently undervalued (and often overlooked in the production of fine craft felt). These wools are frequently referred to as ‘waste’ wools. The research further explores aspects of the UK’s wool economy and the problematic issue of waste wool. The aim being to locate and articulate the creative potential of a selection of these wools within the field of fine felt craft practice, and in so doing raise an awareness of their potential diversity and relevance. The investigation questions felt’s marginal status within the textile hierarchy, and problematizes notions of the familial and self-conscious attributed to felt craft by some of its makers. By examining distinctions between craft and industrial felt production, the research considers both the opportunities and limitations of these relationships within the context of designer maker practice. The purpose and focus of this material-led examination is to develop inventive, progressive methods in fine felt craft and couture application seeking material currency with appropriate use of waste wools for handwork production. The practical experimentation was conducted using a practice-led research approach through which materials and sampling methods emerged within a studio-based environment. The study focuses on the use of carding, wet and dry felting and post felting manipulation of surface design using hand-pleating applications. Whilst not specifically suggesting new techniques in felt-making, the modification of existing processes has formed a central part of the contribution to new knowledge created within the work. Therefore the qualitative nature of the research methodology establishes a new perspective on both the value and integrity of British waste wools for the production of fine craft felt-making. The portfolio of fabrics produced confirmed the suitability of materials for fine craft felt-making and further suggested their appropriateness for product development and use. The fabric prototypes and exposition collection evidence new design concepts, situating the practical investigations in a cultural and critical context and in so doing reposition the material in a more valuable and original light. The sampling process identified key areas for innovation and aesthetic appeal suggesting that further research could be developed using other wools and wool blends. From this thesis emerges a vibrant platform for fresh interpretation and potential for British waste wools in fine craft felt-making, further strengthening the creative interplay between material and technique.

title: Improvisation and teacher expertise: a comparative case study
Creators: name: Sorensen, N
Publisher: name: Bath Spa University
Year: 2014

description: This thesis reports on an enquiry into the nature of teacher expertise which pays particular attention to its improvisatory nature. The study draws on three main areas of literature and theory: critical studies in improvisation; expertise and expert practice and organisation theory. These are used to present a model of teacher expertise that is derived from grounded theory. The data is taken from a series of comparative case studies of seven experienced teachers working in secondary schools in the South West of England and who have been identified as being expert within their school setting. Constant comparative methods of analysis have been used to draw out themes from the data. This has contributed to a grounded theory that identifies the nature of teacher expertise. The findings that arise from the data are that teachers' expertise is best expressed as continually evolving practice, a process as opposed to an end state. Advanced professional practice is best described as a 'teacher with expertises' and this is preferable to the term 'expert teacher'. The data shows that teacher expertise is fundamentally improvisatory and that this has a positive impact on the quality of teaching. The improvisation nature of teacher expertise is derived from four processes: the expression of tacit knowledge, relational and interactional practice, personalisation of the learning environment and self reflection leading to the continual adaptation of pedagogy. The resulting model of teacher expertise casts new light on how we understand advanced professional practice and this has implications for school leaders, teachers, researchers and those with responsibility for the initial training and the continuing professional development of teachers.

description: Cellular networks are not merely data access networks to the Internet. Their distinct services and ability to form large complex compounds for roaming purposes make them an attractive research target in their own right. Their promise of providing a consistent service with comparable privacy and security across roaming partners falls apart at close inspection. Thus, there is a need for controlled testbeds and measurement tools for cellular access networks doing justice to the technology’s unique structure and global scope. Particularly, such measurements suffer from a combinatorial explosion of operators, mobile plans, and services. To cope with these challenges, we built a framework that geographically decouples the SIM from the cellular modem by selectively connecting both remotely. This allows testing any subscriber with any operator at any modem location within minutes without moving parts. The resulting GSM/UMTS/LTE measurement and testbed platform offers a controlled experimentation environment, which is scalable and cost-effective. The platform is extensible and fully open-sourced, allowing other researchers to contribute locations, SIM cards, and measurement scripts. Using the above framework, our international experiments in commercial networks revealed exploitable inconsistencies in traffic metering, leading to multiple phreaking opportunities, i.e., fare-dodging. We also expose problematic IPv6 firewall configurations, hidden SIM card communication to the home network, and fingerprint dial progress tones to track victims across different roaming networks and countries with voice calls.

description: Tortuosity is one of the key parameters describing the geometry and transport properties of porous media. It is defined either as an average elongation of fluid paths or as a retardation factor that measures the resistance of a porous medium to the flow. However, in contrast to a retardation factor, an average fluid path elongation is difficult to compute numerically and, in general, is not measurable directly in experiments. We review some recent achievements in bridging the gap between the two formulations of tortuosity and discuss possible method of numerical and an experimental measurements of the tortuosity directly from the fluid velocity field.

description: DMTF is a standards organization by major industry players in IT infrastructure including AMD, Alibaba, Broadcom, Cisco, Dell, Google, Huawei, IBM, Intel, Lenovo, and NVIDIA, which aims to enable interoperability, e.g., including cloud, virtualization, network, servers and storage. It is currently standardizing a security protocol called SPDM, which aims to secure communication over the wire and to enable device attestation, notably also explicitly catering for communicating hardware components. The SPDM protocol inherits requirements and design ideas from IETF’s TLS 1.3. However, its state machines and transcript handling are substantially different and more complex. While architecture, specification, and open-source libraries of the current versions of SPDM are publicly available, these include no significant security analysis of any kind. In this work we develop the first formal models of the three modes of the SPDM protocol version 1.2.1, and formally analyze their main security properties
title: Literacy on the edge : three to eight year-olds make meaning
Creators: name: Hattingh, L
Publisher: name: Bath Spa University
Year: 2014

description: Three to eight-year-old children’s spontaneous and creative actions provide them with opportunities to call on their own stories and life experiences in their symbolic representations. Their symbolic representations offer a window onto their identities and their meanings, while providing the adults around them with an insight into their world by constructing meaning from the children’s activities. These representations are frequently composed in the unofficial spaces that children inhabit, on the edges of the main literacy teaching and learning activities of the classroom, nursery playroom and home, and are indicative of the children’s social worlds and literacy practices, made visible in their artefacts as they draw, model, make marks and role play. The study takes place in a small nursery and primary school, and consists of ethnographic case studies which allow for the scrutiny and analysis of the artefacts made by the children at home and at school. The data comprise images of fifteen children's representations, supported by field notes and conversational interviews. The analysis of the data recognises the need for a respectful and ethical approach to the interpretation of children's meaningmaking strategies. Role play, drawings, cut-outs and selected artefacts and found objects are some of the methods and contexts children employ to express their voices and to build theories of action through reflection and representation of their thoughts, experiences and feelings. The children's meanings provide opportunities for exploration, experimentation and critical thinking. The approach, which is taken in the interpretation of the children's attempts to communicate meaning through their symbolic representations, reflects an ethical pedagogy where the child is listened to and their meaningmaking is interpreted on their own terms. The thesis argues that literacy is predicated on making meaning, and that this should be supported by recognising the need for children to communicate and make their meanings visible in their artefacts and symbolic behaviour. The findings support the thesis and suggest that there is a need to acknowledge that young children are literate in the way in which they use their symbolic representations to say what they mean, and that the richness of children’s meaning-making practices is particularly evident when they are engaged on the periphery, or edges, of the main literacy activities in their homes and educational settings.
The semi-classical expansion and resurgence in gauge theories: new perturbative, instanton, bion, and renormalon effects

description: We study the dynamics of four dimensional gauge theories with adjoint fermions for all gauge groups, both in perturbation theory and non-perturbatively, by using circle compactification with periodic boundary conditions for the fermions. There are new gauge phenomena. We show that, to all orders in perturbation theory, many gauge groups are Higgsed by the gauge holonomy around the circle to a product of both abelian and nonabelian gauge group factors. Non-perturbatively there are monopole-instantons with fermion zero modes and two types of monopole-anti-monopole molecules, called bions. One type are "magnetic bions" which carry net magnetic charge and induce a mass gap for gauge fluctuations. Another type are "neutral bions" which are magnetically neutral, and their understanding requires a generalization of multi-instanton techniques in quantum mechanics - which we refer to as the Bogomolny-Zinn-Justin (BZJ) prescription - to compactified field theory. The BZJ prescription applied to bion-anti-bion topological molecules predicts a singularity on the positive real axis of the Borel plane (i.e., a divergence from summing large orders in peturbation theory) which is of order N times closer to the origin than the leading 4-d BPST instanton-anti-instanton singularity, where N is the rank of the gauge group. The position of the bion--anti-bion singularity is thus qualitatively similar to that of the 4-d IR renormalon singularity, and we conjecture that they are continuously related as the compactification radius is changed. By making use of transseries and Ecalle's resurgence theory we argue that a non-perturbative continuum definition of a class of field theories which admit semi-classical expansions may be possible.

title: Mark making and melancholia in painting : a language for visual representation of the melancholic
Creators: name: Newton, M.W
Publisher: name: Bath Spa University
Year: 2014

description: Introduction – Research Question:- What are the elements (marks) that support a melancholic narrative in painting and in particular how can they be harnessed to heighten the feeling and create an ‘authentic’ melancholic work from a painting of simple and natural motifs? I summarise the changes in the meaning of the term melancholia, especially in the last two centuries, and discuss the validity of melancholy painting today. I summarise the key developments to the debate in the 1980s between the artists and the theoretical art critics and hypothesise that paintings that refer to this ‘death of painting’ are inherently melancholic. I seek out the “language of marks” for expressing melancholy by extrapolating from an examination of 100 paintings but fail in my attempt to quantify them objectively. The assumption that feeling is grounded in the formal properties is tested through detailed examination and subjective analysis of key extant works, concentrating specifically on how colour and expressive mark-making can be used by the artist to enhancing the emotional content. I use examples of extant paintings to show that it is possible to use context as a way of adding to the melancholic content of a contemporary painting. Practical Study:- The practical research takes the form of painted samples, copies of extant contemporary works, explorations of melancholic motifs (metaphors) and finally a body of work testing the integration of the theoretical analysis with the practical work. Conclusions:- In addition to melancholic meaning being grounded in the formal properties of a painting, expressive marks can be appropriated and re-presented but the requirement for them to be authentic is open to conjecture. However, referencing the ‘death of painting’ can enhance melancholic content without the use of irony or becoming kitsch.
Efficient Shared Memory Algorithms for Bounding Space

description: It is the state of the art that computer systems use multi-core architectures. In order to exploit the benefits of parallelism, multiple processors have to cooperate and concurrently communicate by executing operations on shared objects. It is challenging in shared memory algorithms to deal with the inherent asynchrony of processes. To overcome this difficulty and to achieve high efficiency, algorithm designers often assume unbounded space. This work focuses on designing time-efficient shared memory algorithms while avoiding unbounded space. One example is that of making shared objects writable: Many standard primitives (for instance, compare-and-swap or fetch-and-add) do not provide a Write() operation that unconditionally changes the object's state to the one provided as a parameter. Adding Write() operations without sacrificing efficiency is challenging if space is limited. We provide a space-efficient solution for making synchronization primitives writable with optimal step complexity. A special case of making an object writable is to augment non-resettable objects with Reset() operations. We show how our general transformation can be improved to achieve optimal space implementations of long-lived test-and-set objects with time-efficient Reset() operations. Another example concerns the ABA problem: Even though a process retrieves the same value twice in a row from a shared object, it is still possible that the value of the object has changed multiple times. We investigate the time and space complexity of detecting ABAs in shared memory algorithms for systems with bounded base objects. To that end, we propose a new primitive called an ABA-detecting register, and we give an efficient implementation of this type using asymptotically optimal number of bounded registers. Finally we deal with a more general unbounded space problem: Many applications employ the tagging technique, where shared objects get augmented with additional values, called tags. Unbounded tags are mainly used in those applications, because bounding them is too complicated and error prone. We introduce a new primitive that provides an abstraction for avoiding unbounded tags. Also, we propose optimally time-efficient implementations of this primitive from bounded objects. In addition to straightforward applications that use tags directly, our implementations can also often be used for memory reclamation.

description: Despite remarkable improvements, automatic speech recognition is susceptible to adversarial perturbations. Compared to standard machine learning architectures, these attacks against speech recognition are significantly more challenging, especially since the inputs to a speech recognition system are time series that contain both acoustic and linguistic properties of speech. Extracting all recognition-relevant information requires more complex pipelines and an ensemble of specialized components. Consequently, an attacker needs to consider the entire pipeline. In this paper, we present VENOMAVE, the first training time poisoning attack against speech recognition. Similar to the pre-dominantly studied evasion attacks, we pursue the same goal: leading the system to an incorrect, and attacker-chosen transcription of a target audio waveform. In contrast to evasion attacks, however, we assume that the attacker can only manipulate a small part of the training data without altering the target audio waveform at run time. We evaluate our attack on two datasets: TIDIGITS and Speech Commands. When poisoning less than 0.17 % of the dataset, VENOMAVE achieves attack success rates of over 80.0 %, without access to the victim’s network architecture or hyperparameters. In a more realistic scenario, when the target audio waveform is played over the air in different rooms, VENOMAVE maintains a success rate of up to 73.3%. Finally, VENOMAVE achieves an attack transferability rate of 36.4 % between two different model architectures
Expression and structural characterization of the p8 major coat protein from B5 filamentous bacteriophage
Creators: name: Bo, Htet Ei
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is based on work done on the expression, purification and structural characterization of the major coat protein of B5 bacteriophage. The major coat proteins of bacteriophages have long been utilized to understand membrane proteins and membrane-associated assembly. It is the special feature of the major coat protein to exist in different environments that holds the key to its involvement in phage assembly. The structure of p8 in the different environments, especially in the host membrane, has to be fully understood before the mystery of phage assembly can be solved. The major coat protein of B5, p8, has been chosen in this study because B5 infects Gram positive bacteria and the structure of p8 in an appropriate model membrane can better represent its native structure in the host membrane. In Chapter 1, I introduce background information on filamentous phage, and the debate of major coat protein structure. The different structures that already exist for the major coat protein in virion, in host membranes, and during phage assembly are discussed. In the next chapter, I present the steps required to obtain pure p8 using a heterologous bacterial expression system. The optimizations and considerations needed to express and purify p8 are discussed thoroughly. The considerations taken for p8 expression can essentially be applied to other membrane protein expression. In the same chapter, an I32C mutant of p8 is also designed, expressed and successfully purified. The technique used to introduce the single substitution mutation to p8 can be applied to other protein mutation experiments. In the subsequent chapter, p8 structure is studied using circular dichroism (CD), nuclear magnetic resonance (NMR) and site directed labeling with a 6-bromoacetyl-2- dimethylaminonaphthalene (BADAN) fluorescence probe. The results from CD show that p8 has high alpha helicity when reconstituted into lipid compositions that represent the Gram positive membrane. Preliminary NMR experiments have been performed and conditions to obtain optimal NMR spectra have been explored. BADAN fluorescence labeling experiments have been trialed and have been shown to successfully indicate the local environment of residue 32 to which BADAN is attached. Finally, possible future work is discussed.

description: We use chiral perturbation theory (ChPT) to calculate the $π^- d$ scattering length with an accuracy of a few percent, including isospin-violating corrections both in the two- and three-body sector. In particular, we provide the technical details of a recent letter, where we used data on pionic deuterium and pionic hydrogen atoms to extract the isoscalar and isovector pion-nucleon scattering lengths $a^+$ and $a^-$. We study isospin-breaking contributions to the three-body part of $a_{π^-d}$ due to mass differences, isospin violation in the $πN$ scattering lengths, and virtual photons. This last class of effects is ostensibly infrared enhanced due to the smallness of the deuteron binding energy. However, we show that the leading virtual-photon effects that might undergo such enhancement cancel, and hence the standard ChPT counting provides a reliable estimate of isospin violation in $a_{π^- d}$ due to virtual photons. Finally, we discuss the validity of the Goldberger-Miyazawa-Oehme sum rule in the presence of isospin violation, and use it to determine the charged-pion-nucleon coupling constant.

description: Recent measurement of mass of PSR J1614-2230 rules out most of existing models of equation of state (EOS) of dense matter with high-density softening due to hyperonization or a phase transition to quark matter or a boson condensate. We look for a solution of an apparent contradiction between the consequences stemming from up-to-date hypernuclear data, indicating appearance of hyperons at 3 nuclear densities and existence of a two-solar-mass neutron star. We consider a non-linear relativistic mean field (RMF) model involving baryon octet coupled to meson fields. An effective lagrangian includes quartic terms in the meson fields. The values of the parameters of the model are obtained by fitting semi-empirical parameters of nuclear matter at the saturation point, as well as potential wells for hyperons in nuclear matter and the strength of the Lambda-Lambda attraction in double-Lambda hypernuclei. We propose a non-linear RMF model which is consistent with up-to-date semiempirical nuclear and hypernuclear data and allows for neutron stars with hyperon cores and M larger than 2 solar masses. The model involves hidden-strangenes scalar and vector mesons, coupled to hyperons only, and quartic terms involving vector meson fields. Our EOS involving hyperons is stiffer than the corresponding nucleonic EOS (with hyperons artificially suppressed) above five nuclear densities. Required stiffening is generated by the quartic terms involving hidden-strangeness vector meson.

description: Currently, targeting the autophagic pathway is regarded as a promising new strategy for cancer drug discovery. Here, we screened the North China Pharmaceutical Group Corporation's pure compound library of microbial origin using GFP-LC3B-SKOV3 cells and identified elaiophylin as a novel autophagy inhibitor. Elaiophylin promotes autophagosome accumulation but blocks autophagic flux by attenuating lysosomal cathepsin activity, resulting in the accumulation of SQSTM1/p62 in various cell lines. Moreover, elaiophylin destabilizes lysosomes as indicated by LysoTracker Red staining and CTSB/cathepsin B and CTSD/ cathepsin D release from lysosomes into the cytoplasm. Elaiophylin eventually decreases cell viability, especially in combination with cisplatin or under hypoxic conditions. Furthermore, administration of a lower dose (2 mg/kg) of elaiophylin as a single agent achieves a significant antitumor effect without toxicity in an orthotopic ovarian cancer model with metastasis; however, high doses (8 mg/kg) of elaiophylin lead to dysfunction of Paneth cells, which resembles the intestinal phenotype of ATG16L1-deficient mice. Together, these results provide a safe therapeutic window for potential clinical applications of this compound. Our results demonstrate, for the first time, that elaiophylin is a novel autophagy inhibitor, with significant antitumor efficacy as a single agent or in combination in human ovarian cancer cells, establishing the potential treatment of ovarian cancer by this compound.

description: Mergers of two carbon-oxygen white dwarfs have long been suspected to be progenitors of Type Ia Supernovae. Here we present our modifications to the cosmological smoothed particle hydrodynamics code Gadget to apply it to stellar physics including but not limited to mergers of white dwarfs. We demonstrate a new method to map a one-dimensional profile of an object in hydrostatic equilibrium to a stable particle distribution. We use the code to study the effect of initial conditions and resolution on the properties of the merger of two white dwarfs. We compare mergers with approximate and exact binary initial conditions and find that exact binary initial conditions lead to a much more stable binary system but there is no difference in the properties of the actual merger. In contrast, we find that resolution is a critical issue for simulations of white dwarf mergers. Carbon burning hotspots which may lead to a detonation in the so-called violent merger scenario emerge only in simulations with sufficient resolution but independent of the type of binary initial conditions. We conclude that simulations of white dwarf mergers which attempt to investigate their potential for Type Ia supernovae should be carried out with at least 10^6 particles.

description: Heuristics for user experience state that users will transfer their expectations from one product to another. A lack of consistency between products can increase users' cognitive friction, leading to frustration and rejection. This paper presents the first systematic study of the external, functional consistency of two-factor authentication user journeys on top-ranked websites. We find that these websites implement only a minimal number of design aspects consistently (e.g., naming and location of settings) but exhibit mixed design patterns for setup and usage of a second factor. Moreover, we find that some of the more consistently realized aspects, such as descriptions of two-factor authentication, have been described in the literature as problematic and adverse to user experience. Our results advocate for more general UX guidelines for 2FA implementers and raise new research questions about the 2FA user journeys.

description: A cloud of cold N two-level atoms driven by a resonant laser beam shows cooperative effects both in the scattered radiation field and in the radiation pressure force acting on the cloud center-of-mass. The induced dipoles synchronize and the scattered light presents superradiant and/or subradiant features. We present a quantum description of the process in terms of a master equation for the atomic density matrix in the scalar, Born-Markov approximations, reduced to the single-excitation limit. From a perturbative approach for weak incident field, we derive from the master equation the effective Hamiltonian, valid in the linear regime. We discuss the validity of the driven timed Dicke ansatz and of a partial wave expansion for different optical thicknesses and we give analytical expressions for the scattered intensity and the radiation pressure force on the center of mass. We also derive an expression for collective suppression of the atomic excitation and the scattered light by these correlated dipoles.

description: The Rev. Prelate Edmund Sikorski graduated from the High School no. 2 in Brodnica in 1965. In the same year he entered the Seminary of Pelplin. In 1966 - 1968 he was drafted as a seminarian to com pulsory military service, JW. 4413 in Bartoszyce. He served for two years in the same platoon as Blessed Fr. Jerzy Popiełuszko. He was ordained as a priest on May 21, 1972 in the parish church of Brodnica. After completion of the Seminary and ordination, the Rev. Edmund Sikorski worked as a priest in several parishes, in Bydgoszcz - Fordon in the Church of St. Nicholas (1985), Bydgoszcz - Fordon in the Church of St. Matthew (1985-2008). In 1985, as a parish priest, the Rev. Edmund Sikorski started organization of a parish and construction of the Church of St. Mathew , Apostle and Evangelist, 4 Skarzyńskiego Street in Bydgoszcz, and a parish center. He personally supervised progress of works. During the period of democratic changes, the Rev. Edmund Sikorski supported NSZZ Solidarity and during martial law in 1980-1989 he actively supported people who were repressed. Starting from 1985, in his activity as parish priest of St. Mathew’s Parish, he has organized many charitable campaigns, pilgrim ages and camps for the young people from Fordon. He has also been involved in educational activities, cooperating with schools. Since 1990 to this day, i.e. for 30 years, he has worked as chaplain of the Sokół Gymnastic Society. In 2017, by the decision of the President of Poland, he was promoted to the rank of second lieutenant of the Polish Army.

description: The width and shape of photon burst histograms pose significant limitations to the identification of single molecules in micro/nano-fluidic channels, and the nature of these histograms is not fully understood. To reach a deeper understanding, we performed computer simulations based on a Gaussian beam intensity profile with various fluidic channel diameters and assuming (i) a deterministic (noise-free) case, (ii) photon emission/absorption noise, and (iii) photon noise with diffusion. Photon noise in narrow channels yields a Gaussian burst distribution while additional strong diffusion produces skewed histograms. We use the fluctuating residence time picture [Phys. Rev. Lett. 80, 2386-2388 (1998)] and conclude that the skewness of the photon number distribution is caused by the longitudinal diffusive component of the motion of the molecules as they traverse the laser beam. In the case of strong diffusion in narrow channels, this effect leads to a log-normal distribution. We show that the same effect can transform the separate peaks of the photon burst histograms of multiple molecule mixtures into a single log-normal shape.

The Cops and Robber game on graphs with forbidden (induced) subgraphs

description: The two-player, complete information game of Cops and Robber is played on undirected finite graphs. A number of cops and one robber are positioned on vertices and take turns in sliding along edges. The cops win if, after a move, a cop and the robber are on the same vertex. The minimum number of cops needed to catch the robber on a graph is called the cop number of that graph.

In this paper, we study the cop number in the classes of graphs defined by forbidding one or more graphs as either subgraphs or induced subgraphs. In the case of a single forbidden graph we completely characterize (for both relations) the graphs which force bounded cop number.

In closing, we bound the cop number in terms of the tree-width.

TALUS: Reinforcing TEE Confidentiality with Cryptographic Coprocessors

description: Platforms are nowadays typically equipped with trusted execution environments (TEEs), such as Intel SGX or ARM TrustZone. However, recent microarchitectural attacks on TEEs repeatedly broke their confidentiality guarantees, including the leakage of long-term cryptographic secrets. These systems are typically also equipped with a cryptographic coprocessor, such as a TPM or Google Titan. These coprocessors offer a unique set of security features focused on safeguarding cryptographic secrets. Still, despite their simultaneous availability, the integration between these technologies is practically nonexistent, which prevents them from benefitting from each other’s strengths. In this paper, we propose TALUS , a general design and a set of three main requirements for a secure symbiosis between TEEs and cryptographic coprocessors. We implement a proof-of-concept of TALUS based on Intel SGX and a hardware TPM. We show that with TALUS, the long-term secrets used in the SGX life cycle can be moved to the TPM. We demonstrate that our design is robust even in the presence of transient execution attacks, preventing an entire class of attacks due to the reduced attack surface on the shared hardware.
Detecting non-magnetic excitations in quantum magnets

description: Many unconventional quantum phases host special non-magnetic excitations such as photons and visons. We discuss two possible ways to detect these excitations experimentally. Firstly, spin-lattice coupling mixes the excitations with phonons. The phonon spectral function acquires new features that can be detected by neutron or X-ray scattering. Secondly, valence-bond fluctuations translate into charge density fluctuations on non-bipartite lattices. Such charge fluctuations can be characterized by conventional spectroscopies such as Terahertz spectroscopy. Observation of exotic singlet excitations would provide positive identification of unconventional quantum phases in frustrated antiferromagnets.
