title: Characterisation of the function, sequence polymorphism and toxicity of the yeast Rnq1p prion protein
Creators: name: Staniforth, Gemma Louise
Publisher: name: University of Kent
Year: 2021

description: The Saccharomyces cerevisiae Rnq 1 p prion protein plays an integral role in the dynamics of other aggregation-prone proteins, be they other prion proteins or glutamine-rich proteins. The conformational conversion of a prion protein to its prion state is often associated with changes to cellular physiology and two interesting questions arise from this. One, what impact do these physiological changes have on our ability to interpret experimental findings in this model organism? Two, are these changes non-random, representing a novel means of altering cellular physiology? An understanding of the cellular function of Rnq 1 P is important in addressing these questions. Further, the role of Rnq 1 P in its [PIN+] prion state as a universal catalyst for amyloid-formation provides a useful model for dissecting mechanisms of amyloid toxicity, and once again, cellular function is one parameter of multiple that determine the [mal toxicity profile of a protein. To identify a cellular function for Rnqlp both phenotypic assays and a mass spectrometry-based label-free quantitative proteomics analysis were performed. A role for Rnq 1 P as a negative regulator of translation termination was characterised and eo-localisation of Rnq 1 p with P-bodies, tightly packed clusters of untranslating rnRNA, was observed indicating that Rnqlp is intimately associated with mRNA dynamics within the cell. Additionally, evidence for a role in the maintenance of mitochondrial respiratory capacity pertaining to ATP-generation is presented, along with indications that this latter role may be through transcriptional regulation. To further understand the mechanisms of toxic protein aggregation, two analyses were performed. One, a study on the impact of natural Rnqlp polymorphisms identified fifty-three novel RNQI alleles and sequence features affecting Rnq 1 P toxicity. Two, a screen for genetic modifiers of both Rnqlp and mutant huntingtin demonstrated the role of P-bodies and mRNA degradation pathways in modulating amyloid or glutamine-based toxicity, along with a possible role for energy. homeostasis. The results presented in this thesis provided new insight into the functional roles of Rnq 1 P within the cell, and consequently the possible impact on cellular physiology associated with Rnqlp's [pin-] to [PIN+] conversion, and also identified novel modulators of toxic aggregation events in the cell.

description: Reinforcement learning is a promising model-free and adaptive controller for demand side management, as part of the future smart grid, at the district level. This paper presents the results of the algorithm that was submitted for the CityLearn Challenge, which was hosted in early 2020 with the aim of designing and tuning a reinforcement learning agent to flatten and smooth the aggregated curve of electrical demand of a district of diverse buildings. The proposed solution secured second place in the challenge using a centralised 'Soft Actor Critic' deep reinforcement learning agent that was able to handle continuous action spaces. The controller was able to achieve an averaged score of 0.967 on the challenge dataset comprising of different buildings and climates. This highlights the potential application of deep reinforcement learning as a plug-and-play style controller, that is capable of handling different climates and a heterogenous building stock, for district demand side management of buildings.

description: Two-dimensional gas-dynamical modeling of the mass-flow structure is used to study the outburst development in the classical symbiotic star Z And. The stage-by-stage rise of the light during the outburst can be explained in the framework of the colliding winds model. We suggest a scenario for the development of the outburst and study the possible influence of the changes of the flow structure on the light of the system. The model variations of the luminosity due to the formation of a system of shocks are in good agreement with the observed light variations.

description: Pulmonary imaging measurements using magnetic resonance imaging (MRI) and computed tomography (CT) have the potential to deepen our understanding of chronic obstructive pulmonary disease (COPD) by measuring airway and parenchymal pathologic information that cannot be provided by spirometry. Currently, MRI and CT measurements are not included in mortality risk predictions, diagnosis, or COPD staging. We evaluated baseline pulmonary function, MRI and CT measurements alongside imaging texture-features to predict 10-year all-cause mortality in ex-smokers with (n = 93; 31 females; 70 ± 9years) and without (n = 69; 29 females, 69 ± 9years) COPD. CT airway and vessel measurements, helium-3 (3He) MRI ventilation defect percent (VDP) and apparent diffusion coefficients (ADC) were quantified. MRI and CT texture-features were extracted using PyRadiomics (version2.2.0). Associations between 10-year all-cause mortality and all clinical and imaging measurements were evaluated using multivariable regression model odds-ratios. Machine-learning predictive models for 10-year all-cause mortality were evaluated using area-under-receiver-operator-characteristic-curve (AUC), sensitivity and specificity analyses. DLCO (%pred) (HR = 0.955, 95%CI: 0.934-0.976, p < 0.001), MRI ADC (HR = 1.843, 95%CI: 1.260-2.871, p < 0.001), and CT informational-measure-of-correlation (HR = 3.546, 95% CI: 1.660-7.573, p = 0.001) were the strongest predictors of 10-year mortality. A machine-learning model trained on clinical, imaging, and imaging textures was the best predictive model (AUC = 0.82, sensitivity = 83%, specificity = 84%) and outperformed the solely clinical model (AUC = 0.76, sensitivity = 77%, specificity = 79%). In ex-smokers, regardless of COPD status, addition of CT and MR imaging texture measurements to clinical models provided unique prognostic information of mortality risk that can allow for better clinical management.Clinical Trial Registration: www.clinicaltrials.gov NCT02279329

description: To efficiently manipulate magnetism is a key physical issue for modern condensed matter physics, which is also crucial for magnetic functional applications. Most previous relevant studies rely on the tuning of spin texture, while the spin orientation is often negligible. As an exception, spin-orbit coupled $J_{\rm eff}$ states of $4d$/$5d$ electrons provide an ideal platform for emergent quantum effects. However, many expectations have not been realized due to the complexities of real materials. Thus the pursuit for more ideal $J_{\rm eff}$ states remains ongoing. Here a near-ideal $J_{\rm eff}$=$3/2$ Mott insulating phase is predicted in the family of hexachloro niobates, which avoid some common drawbacks of perovskite oxides. The local magnetic moment is nearly compensated between spin and orbital components, rendering exotic recessive magnetism. More interestingly, the electronic structure and magnetism can be strongly tuned by rotating spin axis, which is rare but crucial for spintronic applications.

description: The attractive Fermi-Hubbard Hamiltonian is solved via the Bogoliubov-de Gennes formalism to analyze the ground state phases of population imbalanced fermion mixtures in harmonically trapped two-dimensional optical lattices. In the low density limit the superfluid order parameter modulates in the radial direction towards the trap edges to accommodate the unpaired fermions that are pushed away from the trap center with a single peak in their density. However in the high density limit while the order parameter modulates in the radial direction towards the trap center for low imbalance, it also modulates towards the trap edges with increasing imbalance until the superfluid to normal phase transition occurs beyond a critical imbalance. This leads to a single peak in the density of unpaired fermions for low and high imbalance but leads to double peaks for intermediate imbalance.

On-Device Power Analysis Across Hardware Security Domains.

Publisher: name: IACR Transactions on Cryptographic Hardware and Embedded Systems
Year: 2019

description: Side-channel power analysis is a powerful method of breaking secure cryptographic algorithms, but typically power analysis is considered to require specialized measurement equipment on or near the device. Assuming an attacker first gained the ability to run code on the unsecure side of a device, they could trigger encryptions and use the on-board ADC to capture power traces of that hardware encryption engine. This is demonstrated on a SAML11 which contains a M23 core with a TrustZone-M implementation as the hardware security barrier. This attack requires 160 × 106 traces, or approximately 5 GByte of data. This attack does not use any external measurement equipment, entirely performing the power analysis using the ADC on-board the microcontroller under attack. The attack is demonstrated to work both from the non-secure and secure environment on the chip, being a demonstration of a cross-domain power analysis attack. To understand the effect of noise and sample rate reduction, an attack is mounted on the SAML11 hardware AES peripheral using classic external equipment, and results are compared for various sample rates and hardware setups. A discussion on how users of this device can help prevent such remote attacks is also presented, along with metrics that can be used in evaluating other devices. Complete copies of all recorded power traces and scripts used by the authors are publicly presented.

description: Public key cryptography protocols, such as RSA and elliptic curve cryptography, will be rendered insecure by Shor’s algorithm when large-scale quantum computers are built. Cryptographers are working on quantum-resistant algorithms, and lattice-based cryptography has emerged as a prime candidate. However, high computational complexity of these algorithms makes it challenging to implement lattice-based protocols on low-power embedded devices. To address this challenge, we present Sapphire – a lattice cryptography processor with configurable parameters. Efficient sampling, with a SHA-3-based PRNG, provides two orders of magnitude energy savings; a single-port RAM-based number theoretic transform memory architecture is proposed, which provides 124k-gate area savings; while a low-power modular arithmetic unit accelerates polynomial computations. Our test chip was fabricated in TSMC 40nm low-power CMOS process, with the Sapphire cryptographic core occupying 0.28 mm2 area consisting of 106k logic gates and 40.25 KB SRAM. Sapphire can be programmed with custom instructions for polynomial arithmetic and sampling, and it is coupled with a low-power RISC-V micro-processor to demonstrate NIST Round 2 lattice-based CCA-secure key encapsulation and signature protocols Frodo, NewHope, qTESLA, CRYSTALS-Kyber and CRYSTALS-Dilithium, achieving up to an order of magnitude improvement in performance and energy-efficiency compared to state-of-the-art hardware implementations. All key building blocks of Sapphire are constant-time and secure against timing and simple power analysis side-channel attacks. We also discuss how masking-based DPA countermeasures can be implemented on the Sapphire core without any changes to the hardware.

description: This paper presents our solution to ACM MM challenge: Large-scale Human-centric Video Analysis in Complex Events\cite{lin2020human}; specifically, here we focus on Track3: Crowd Pose Tracking in Complex Events. Remarkable progress has been made in multi-pose training in recent years. However, how to track the human pose in crowded and complex environments has not been well addressed. We formulate the problem as several subproblems to be solved. First, we use a multi-object tracking method to assign human ID to each bounding box generated by the detection model. After that, a pose is generated to each bounding box with ID. At last, optical flow is used to take advantage of the temporal information in the videos and generate the final pose tracking result.

description: Due to the implementation of the BC Ministry of Education (MoE) new Career Life Education, Career Life Connections and Capstone (CLE/CLC/Capstone) curriculum at the start of the 2018-2019 school year there was a need for secondary schools to create new ways to implement this curriculum. BC secondary schools were responsible for implementing the new program in a way that would best accommodate the needs of the school and learning community. The intent of this Project is represented by the critical challenge question; How can technology be used in a Blended Learning environment to assist in implementing an innovative and sustainable Career Life Education, Career Life Connections (CLE/CLC) and Capstone program that is beneficial and engaging to secondary students? This Project also represents how such a program was implemented into a secondary school timetable and the processes and technology used to create a Blended Learning Career Education program called Connections. The process also includes ways to overcome barriers when looking at implementing a new program into a school organization that was resistant to change. The Project deliverable is presented in a Weebly website resource: http://careeredconnections.weebly.com/ and describes the development and evolution of a Blended Learning format, overcoming potential school site barriers, important learning curricular content and technology used. A breakdown of the program in action since 2018-2019 and adaptations due to the COVID-19 learning disruption of 2020 is also included in the deliverable.

description: Chou suggested a constant-time implementation for quasi-cyclic moderatedensity parity-check (QC-MDPC) code-based cryptography to mitigate timing attacks at CHES 2016. This countermeasure was later found to become vulnerable to a differential power analysis (DPA) in private syndrome computation, as described by Rossi et al. at CHES 2017. The proposed DPA, however, still could not completely recover accurate secret indices, requiring further solving linear equations to obtain entire secret information. In this paper, we propose a multiple-trace attack which enables to completely recover accurate secret indices. We further propose a singletrace attack which can even work when using ephemeral keys or applying Rossi et al.’s DPA countermeasures. Our experiments show that the BIKE and LEDAcrypt may become vulnerable to our proposed attacks. The experiments are conducted using power consumption traces measured from ChipWhisperer-Lite XMEGA (8-bit processor) and ChipWhisperer UFO STM32F3 (32-bit processor) target boards.

description: We present the results of a spectral analysis of 5 Swift XRT and UVOT observations of the BL Lac object PKS 0548-322 carried out over the period April-June 2005. The X-ray flux of this high energy peaked BL Lac (HBL) source was found to be approximately constant at a level of F(2-10 keV) ~ 4x10^-11 erg cm^-2 s^-1, a factor of 2 brighter than when observed by BeppoSAX in 1999 and close to the maximum intensity reported in the Einstein Slew Survey. The very good statistics obtained in the 0.3-10 keV Swift X-ray spectrum allowed us to detect highly significant deviations from a simple power law spectral distribution. A log-parabolic model describes well the X-ray data and gives a best fit curvature parameter of 0.18 and peak energy in the Spectral Energy Distribution of about 2 keV. The UV spectral data from Swift UVOT join well with a power law extrapolation of the soft X-ray data points suggesting that the same component is responsible for the observed emission in the two bands. The combination of synchrotron peak in the X-ray band and high intensity state confirms PKS 0548-322 as a prime target for TeV observations. X-ray monitoring and coordinated TeV campaigns are highly advisable.

description: Randomized controlled trials and observational studies have reported conflicting results on the potential beneficial effects of statins on mortality in patients with chronic obstructive pulmonary disease (COPD). We performed a systematic search of the literature to review all observational studies reporting relative risks of death with statin use in COPD, focusing on potential sources of bias. We identified 15 observational studies, out of 2835, of which 12 were affected by time-related and other biases and the remaining 3 by confounding bias. All 15 studies were also subject to confounding bias due to lack of adjustment for important COPD-related factors. The risk of death associated with statin use was reduced across all 15 studies (pooled relative risk (PRR) 0.66; 95% CI: 0.59-0.74). The reduction was observed in 7 studies with immortal time bias (PRR 0.62; 95%: 0.53-0.72), two with collider-stratification bias (PRR 0.60; 95% CI: 0.45-0.80), one with time-window bias (RR 0.61; 95% CI: 0.38-0.98), one with immeasurable time bias (RR 0.50; 95% CI: 0.40-0.62), and one with exposure misclassification (RR 0.86; 95% CI: 0.72-1.03). The three studies that avoided these biases were, however, affected by confounding bias resulting in a PRR of 0.77 (95% CI: 0.61-0.98). In conclusion, the observational studies investigating statin use and mortality in COPD are affected by major biases, many of which can result in spurious protective effects. Well-designed observational studies that carefully emulate randomized trials are needed to resolve this uncertainty regarding the potential beneficial benefits of statins on mortality in patients with COPD.

By reflecting on this process, I was able to create helpful and useful content into detailing the process of constructing a High School stage production. The video footage was taken and edited into seven video reflections or episodes, focusing on each of the essential aspects of stage production; Script, Auditions, Dramatic Warm Ups, Dramatic instruction, Budget and Finances, Advertising, Venue, and The Show. The series is posted on a website that streams each episode, and features resources and the tools used, and reviewed, in the episode. With this new online platform, and visual demonstrations, the steps for Drama teachers to create their own stage production will be highlighted to make the whole process a less daunting task, and teachers can consider the Critical Challenge Question posed by this Masters degree investigation.

description: Preparation and measurement of physical systems are the operational building blocks of any physical experiment, and to describe them is the first purpose of any physical theory. It is remarkable that, in some situations, even when only preparation and measurement devices of a single system are present and they are uncharacterized, it is possible to distinguish between the behaviours of quantum and classical systems relying only on observational data. Certifying the physical origin of measurement statistics in the prepare and measure scenario is of primal importance for developing quantum networks, distributing quantum keys and certifying randomness, to mention a few applications, but, surprisingly, no general methods to do so are known. We progress on this problem by crafting a general, sufficient condition to certify that a given set of preparations can only generate classical statistics, for any number of generalized measurements. As an application, we employ the method to demonstrate non-classicality activation in the prepare and measure scenario, also considering its application in random access codes. Following that, we adapt our method to certify, again through a sufficient condition, whether a given set of measurements can never give rise to non-classical behaviors, irrespective of what preparations they may act upon. This, in turn, allows us to find a large set of incompatible measurements that cannot be used to demonstrate non-classicality, thus showing incompatibility is not sufficient for non-classicality in the prepare and measure scenario.

description: The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date ($z$=0.033) and is the clearest example of a SN associated with a Swift GRB with the earliest optical spectroscopy. Its optical data showed that this is the fastest evolving and among the least luminous GRB-SNe (70% as luminous as SN1998bw). However, its expansion velocity and a comparison with other stripped-envelope SNe suggest that SN2006aj is an intermediate object between Type Ic GRB-SNe and those not accompained by a GRB. High-resolution optical spectroscopy together with SDSS pre-burst observations revealed that the host galaxy of SN2006aj is a low-luminosity, metal-poor star-forming dwarf galaxy.

description: The problem of information leakage through electromagnetic waves for various devices has been extensively discussed in literature. Conventionally, devices that are under such a threat suffer from potential electromagnetic information leakage during their operation. Further, the information inside the devices can be obtained by monitoring the electromagnetic waves leaking at the boundaries of the devices. The leakage of electromagnetic waves, however, was not observed for some devices, and such devices were not the target of the threat discussed above. In light of this circumstance, this paper discusses an “interceptor” that forces the leakage of information through electromagnetic waves, even from devices in which potential electromagnetic leakage does not occur. The proposed interceptor is a small circuit consisting of an affordable semiconductor chip and wiring and is powered by electromagnetic waves that irradiate from the outside of a device as its driving energy. The distance at which information is obtained is controlled by increasing the intensity of the irradiated electromagnetic waves. The paper presents the structure of the circuit for implementing the proposed interceptor to be used in major input–output devices and cryptographic modules, mounting a pathway designed on the basis of the construction method onto each device. Moreover, it is shown that it is possible to forcefully cause information leakage through electromagnetic waves. To detect the aforementioned threat, the paper also focuses on the changes in a device itself and the surrounding electromagnetic environment as a result of mounting an interceptor and considers a method of detecting an interceptor by both passive and active monitoring methods.

description: Personal experience suggests that the continued use of (predominantly) traditional learning practices in senior classrooms, including applied mathematics, is not in the best interests of either learners or educators. While the apparent need for change is seldom argued, change occurs slowly — if it happens at all. Some reluctance on the part of educators may be based on fears of increasing an already demanding workload, or lack of confidence regarding what to do and how to do it. The juggernaut of math education does not readily change direction.The purpose of this project was to provide a choice of alternatives to traditional direct instruction with paper and pencil practice, for the delivery of applied mathematics at the grade 10 level. Access to a web-resource in which students can experience some (guided) autonomy — within the BC 2018 curriculum guidelines — may allow students to achieve greater success and educators may be encouraged to try different approaches. The project was supported by current research in the fields of online instruction, with a focus on mathematics, and exploration of student-focused independent learning methods, including the principles of game design, while incorporating aspects of contemporary best-practices pedagogy. The paper and project are guided by the Critical Challenge Question: 'How can a traditional Workplace Math 10 course be re-designed to provide personalized, online, on demand delivery?' The Major Project is a web-based resource that provides access to materials sufficient to deliver a multi-modal WP10 course with choice of pace, path and process for students, supported by rigorous research, as documented in a companion five-chapter Process Paper.

description: Canary Islands are normally interested by dominant North-East winds that, in some meteorological conditions, can transport sand at high altitude from the Sahara desert. The dust may affect the efficiency of the telescopes and decreases the transparency of the sky. In order to maximize the scientific return of the telescopes located at the ORM, we present an analysis of the atmospheric dust content and its effects on astronomical observations. B, V and I dust aerosol astronomical extinction are derived. Using a 5 years series database of data taken from the four channel TNG dust monitor, we compute a mean hourly and daily values of the dust content. We have detected particles having size 0.3, 0.5, 1.0 and 5.0 um. Using a power law we have derived the content of 10.0 um particles. We found a typical local dust concentration ranging from 3x10^6 particles per cubic meter at 0.3 um, to 10^3 at 5.0 um and 10 at 10.0 um, increasing up to 3 order of magnitudes during the dust storms, with a relative higher increase of 1.0, 5.0 and 10.0 um particles. The number of local dust storm events is the same in winter- and summertime, but, the average background and storm-related increases in the dust concentration in summer are significantly higher than in winter. In a uniform approximation, during the dust storms, an average height of the dust layer of 2.5 km above the telescope is inferred. During the sand storms La Palma Island is affected by an almost uniform layer extending up to 5 km above the sea level, down, at least the height of the telescope. The visible extinction is dominated by particles at 1.0, 5.0 and 10.0 um. In agreement with the results from Carlsberg Automatic Meridian Circle (CAMC) we find a typical extinction during dust storms of about 0.2 mag/airmass.

description: In this letter we study a reference model in theoretical ecology, the disordered Lotka-Volterra model for ecological communities, in the presence of finite demographic noise. Our theoretical analysis, which takes advantage of a mapping to an equilibrium disordered system, proves that for sufficiently heterogeneous interactions and low demographic noise the system displays a multiple equilibria phase, which we fully characterize. In particular, we show that in this phase the number of stable equilibria is exponential in the number of species. Upon further decreasing the demographic noise, we unveil a "Gardner" transition to a marginally stable phase, similar to that observed in jamming of amorphous materials. We confirm and complement our analytical results by numerical simulations. Furthermore, we extend their relevance by showing that they hold for others interacting random dynamical systems, such as the Random Replicant Model. Finally, we discuss their extension to the case of asymmetric couplings.

description: We derive two multivariate generating functions for three-dimensional Young diagrams (also called plane partitions). The variables correspond to a colouring of the boxes according to a finite Abelian subgroup G of SO(3). We use the vertex operator methods of Okounkov--Reshetikhin--Vafa for the easy case G = Z/n; to handle the considerably more difficult case G=Z/2 x Z/2, we will also use a refinement of the author's recent q--enumeration of pyramid partitions. In the appendix, we relate the diagram generating functions to the Donaldson-Thomas partition functions of the orbifold C^3/G. We find a relationship between the Donaldson-Thomas partition functions of the orbifold and its G-Hilbert scheme resolution. We formulate a crepant resolution conjecture for the Donaldson-Thomas theory of local orbifolds satisfying the Hard Lefschetz condition.

New Circuit Minimization Techniques for Smaller and Faster AES SBoxes
Creators: name: Maximov, Alexander

Publisher: name: IACR Transactions on Cryptographic Hardware and Embedded Systems
Year: 2019

description: In this paper we consider various methods and techniques to find the smallest circuit realizing a given linear transformation on n input signals and m output signals, with a constraint of a maximum depth, maxD, of the circuit. Additional requirements may include that input signals can arrive to the circuit with different delays, and output signals may be requested to be ready at a different depth. We apply these methods and also improve previous results in order to find hardware circuits for forward, inverse, and combined AES SBoxes, and for each of them we provide the fastest and smallest combinatorial circuits. Additionally, we propose a novel technique with “floating multiplexers” to minimize the circuit for the combined SBox, where we have two different linear matrices (forward and inverse) combined with multiplexers. The resulting AES SBox solutions are the fastest and smallest to our knowledge.

Measurement of the $ν_e$ and Total $^{8}$B Solar Neutrino Fluxes with the Sudbury Neutrino Observatory Phase I Data Set

description: This article provides the complete description of results from the Phase I data set of the Sudbury Neutrino Observatory (SNO). The Phase I data set is based on a 0.65 kt-year exposure of heavy water to the solar $^8$B neutrino flux. Included here are details of the SNO physics and detector model, evaluations of systematic uncertainties, and estimates of backgrounds. Also discussed are SNO's approach to statistical extraction of the signals from the three neutrino reactions (charged current, neutral current, and elastic scattering) and the results of a search for a day-night asymmetry in the $ν_e$ flux. Under the assumption that the $^8$B spectrum is undistorted, the measurements from this phase yield a solar $ν_e$ flux of $ϕ(ν_e) = 1.76^{+0.05}_{-0.05}{(stat.)}^{+0.09}_{-0.09} {(syst.)} \times 10^{6}$ cm$^{-2}$ s$^{-1}$, and a non-$ν_e$ component $ϕ(ν_{μτ}) = 3.41^{+0.45}_{-0.45}{(stat.)}^{+0.48}_{-0.45} {(syst.)} \times 10^{6}$ cm$^{-2}$ s$^{-1}$. The sum of these components provides a total flux in excellent agreement with the predictions of Standard Solar Models. The day-night asymmetry in the $ν_e$ flux is found to be $A_{e} = 7.0 \pm 4.9 \mathrm{(stat.)^{+1.3}_{-1.2}}% \mathrm{(sys.)}$, when the asymmetry in the total flux is constrained to be zero.

title: Stress programming throughout life history : implications for physiological ageing
Creators: name: Walker, David John
Publisher: name: University of St Andrews

description: Stress exposure throughout life can shape ageing phenotypes by causing changes within an individual’s physiology, such that growth, lifespan and many fitness-related traits are significantly and sometimes permanently affected. Developmental increases in glucocorticoids (GCs) and subsequent programming of the Hypothalamic Pituitary Adrenal (HPA) axis, are considered one of the primary mechanisms that program these age-related physiological changes. However, it is unclear how stress experienced throughout life interacts on physiological processes that may influence the trajectory of the ageing process within an individual. In this thesis, I used the Japanese quail (Coturnix japonica) to investigate both short and long-term effects of developmental and adult stress exposure on physiological processes that are known to be affected by the process of ageing: the neuroimmune system, neural cell death and survival and maintenance of oxidative balance. I aimed to establish at which point during life stress elicited the strongest programming effects; if these effects had physiological costs or benefits for the ageing individual and if there were cumulative or diminishing effects of repeated stress exposure on these physiological processes. Within the neuroimmune system, I found that post-natal stress induced neuroinflammation and caused a reduction in cell survival in later life within brain regions involved in HPA axis functioning. Repeated developmental stress also programmed a dampened apoptotic response in the ageing brain. I also found age and sex-specific effects on apoptosis, cell survival and oxidative balance measures that depended on the conditions birds experienced during development. My data show that programmed long-term changes in physiology are most likely driven by elevated GCs during the post-natal period. My research suggests that these programmed phenotypes may exhibit signs of accelerated physiological ageing or may be adaptive in promoting swifter and stronger recovery from subsequent stress exposure in later life.
Development of Multivariable Prediction Models for the Identification of Patients Admitted to Hospital with an Exacerbation of COPD and the Prediction of Risk of Readmission: A Retrospective Cohort Study using Electronic Medical Record Data

description: Approximately 20% of patients who are discharged from hospital for an acute exacerbation of COPD (AECOPD) are readmitted within 30 days. To reduce this, it is important both to identify all individuals admitted with AECOPD and to predict those who are at higher risk for readmission. To develop two clinical prediction models using data available in electronic medical records: 1) identifying patients admitted with AECOPD and 2) predicting 30-day readmission in patients discharged after AECOPD. Two datasets were created using all admissions to General Internal Medicine from 2012 to 2018 at two hospitals: one cohort to identify AECOPD and a second cohort to predict 30-day readmissions. We fit and internally validated models with four algorithms. Of the 64,609 admissions, 3,620 (5.6%) were diagnosed with an AECOPD. Of those discharged, 518 (15.4%) had a readmission to hospital within 30 days. For identification of patients with a diagnosis of an AECOPD, the top-performing models were LASSO and a four-variable regression model that consisted of specific medications ordered within the first 72 hours of admission. For 30-day readmission prediction, a two-variable regression model was the top performing model consisting of number of COPD admissions in the previous year and the number of non-COPD admissions in the previous year. We generated clinical prediction models to identify AECOPDs during hospitalization and to predict 30-day readmissions after an acute exacerbation from a dataset derived from available EMR data. Further work is needed to improve and externally validate these models.

description: We summarize latest PIC simulation results on the radiation from Poynting jets and strongly magnetized collisionless shocks when a Poynting jet runs into cold ambient medium. We find that in all cases the radiative power output is much below that predicted by synchrotron radiation and the critical frequency is also much lower than the synchrotron critical frequency. We discuss the implications for the interpretation of GRB prompt emission data.

description: Given any diagonal cyclic subgroup $Λ\subset GL(n+1,k)$ of order $d$, let $I_d\subset k[x_0,\ldots, x_n]$ be the ideal generated by all monomials $\{m_{1},\ldots, m_{r}\}$ of degree $d$ which are invariants of $Λ$. $I_d$ is a monomial Togliatti system, provided $r \leq \binom{d+n-1}{n-1}$, and in this case the projective toric variety $X_d$ parameterized by $(m_{1},\ldots, m_{r})$ is called a $GT$-variety with group $Λ$. We prove that all these $GT$-varieties are arithmetically Cohen-Macaulay and we give a combinatorial expression of their Hilbert functions. In the case $n=2$, we compute explicitly the Hilbert function, polynomial and series of $X_d$. We determine a minimal free resolution of its homogeneous ideal and we show that it is a binomial prime ideal generated by quadrics and cubics. We also provide the exact number of both types of generators. Finally, we pose the problem of determining whether a surface parameterized by a Togliatti system is aCM. We construct examples that are aCM and examples that are not.

description: We study the adaptation dynamics of an initially maladapted population evolving via the elementary processes of mutation and selection. The evolution occurs on rugged fitness landscapes which are defined on the multi-dimensional genotypic space and have many local peaks separated by low fitness valleys. We mainly focus on the Eigen's model that describes the deterministic dynamics of an infinite number of self-replicating molecules. In the stationary state, for small mutation rates such a population forms a {\it quasispecies} which consists of the fittest genotype and its closely related mutants. The quasispecies dynamics on rugged fitness landscape follow a punctuated (or step-like) pattern in which a population jumps from a low fitness peak to a higher one, stays there for a considerable time before shifting the peak again and eventually reaches the global maximum of the fitness landscape. We calculate exactly several properties of this dynamical process within a simplified version of the quasispecies model.
