description: In this paper we study some properties of bi-Hamiltonian deformations of Poisson pencils of hydrodynamic type. More specifically, we are interested in determining those structures of the fully deformed pencils that are inherited through the interaction between structural properties of the dispersionless pencils (in particular exactness or homogeneity) and suitable finiteness conditions on the central invariants (like polynomiality). This approach enables us to gain some information about each term of the deformation to all orders in $ε$. Concretely, we show that deformations of exact Poisson pencils of hydrodynamic type with polynomial central invariants can be put, via a Miura transformation, in a special form, that provides us with a tool to map a fully deformed Poisson pencil with polynomial central invariants of a given degree to a fully deformed Poisson pencil with constant central invariants to all orders in $ε$. In particular, this construction is applied to the so called $r$-KdV-CH hierarchy that encompasses all known examples with non-constant central invariants. As far as homogeneous Poisson pencils of hydrodynamic type is concerned, we prove that they can also be put in a special form, if the central invariants are homogeneous polynomials. Through this we can compute the homogeneity degree about the tensorial component appearing in each order in $ε$, namely the coefficient of the highest order derivative of the $δ$.

description: Self-stabilization in distributed systems is a technique to guarantee convergence to a set of legitimate states without external intervention when a transient fault or bad initialization occurs. Recently, there has been a surge of efforts in designing techniques for automated synthesis of self-stabilizing algorithms that are correct by construction. Most of these techniques, however, are not parameterized, meaning that they can only synthesize a solution for a fixed and predetermined number of processes. In this paper, we report a breakthrough in parameterized synthesis of self-stabilizing algorithms in symmetric networks, including ring, line, mesh, and torus. First, we develop cutoffs that guarantee (1) closure in legitimate states, and (2) deadlock-freedom outside the legitimate states. We also develop a sufficient condition for convergence in self-stabilizing systems. Since some of our cutoffs grow with the size of the local state space of processes, scalability of the synthesis procedure is still a problem. We address this problem by introducing a novel SMT-based technique for counterexample-guided synthesis of self-stabilizing algorithms in symmetric networks. We have fully implemented our technique and successfully synthesized solutions to maximal matching, three coloring, and maximal independent set problems for ring and line topologies.

description: Vibrational energy transfer (VET) is essential for protein function. It is responsible for efficient energy dissipation in reaction sites, and has been linked to pathways of allosteric communication. While it is understood that VET occurs via backbone as well as via non-covalent contacts, little is known about the competition of these two transport channels, which determines the VET pathways. To tackle this problem, we equipped the β-hairpin fold of a tryptophan zipper with pairs of non-canonical amino acids, one serving as a VET injector and one as a VET sensor in a femtosecond pump probe experiment. Accompanying extensive non-equilibrium molecular dynamics simulations combined with a master equation analysis unravel the VET pathways. Our joint experimental/computational endeavor reveals the efficiency of backbone vs. contact transport, showing that even if cutting short backbone stretches of only 3 to 4 amino acids in a protein, hydrogen bonds are the dominant VET pathway.
title: Spatial extension of the theoretical framework of the adaptive virulence evolution hypothesis
Creators: name: Fofana, Abdou Moutalab
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: The adaptive virulence hypothesis states that parasites cause death to their hosts
 because virulence is beneficial for the transmission and spread of parasites. A growing
 body of empirical evidence supports the adaptive virulence hypothesis but more
 examples are needed for its empirical validation. The classic mathematical framework
 of the adaptive virulence hypothesis does not account for host population structure
 which can have important implications for virulence evolution. The goal of this thesis
 is to address the broad applicability problems and extend spatially the mathematical
 framework of the adaptive virulence hypothesis by accounting for host movement in
 the model. My thesis examines whether virulence is adaptive at the species level by
 investigating the relationship between virulence and parasite fitness using simulation
 data. I find that virulence and parasite fitness, measured as the basic reproduction
 number R0, are correlated at the between-species level and the exact form of the relationship
 depends on the selective pressures within each group of parasite species.
 Also, I break free from the classic framework of the adaptive virulence hypothesis
 to investigate virulence evolution when parasites reduce host movement. The results
 explain the transient coexistence of low- and high-virulence strains in Avian influenza
 viruses. I reviewed epidemic models with host movement to understand what aspects
 of disease spread are important to develop a spatially extended model for virulence
 evolution. I find that epidemic models with spatially heterogeneous epidemiological
 parameters, like disease transmissibility, are suitable for the spatial extension of the
 mathematical framework of the adaptive virulence hypothesis. Finally, I investigated
 the relationship between the temporal and the spatial spread of infectious diseases. I show an inverse relationship between the initial epidemic growth rate and the spatial
 spread rate which may reflect a trade-off between parasites dispersal and transmission.
 Overall my thesis opens interesting research avenues for future works to formulate
 spatially explicit models for the evolution of virulence and makes significant contributions
 to the empirical investigation of the adaptive virulence hypothesis and the role
 of animal movement for disease spread and virulence evolution.
Gravothermal oscillations in two-component models of star clusters

description: In this paper, gravothermal oscillations are investigated in two-component clusters with a range of different stellar mass ratios and total component mass ratios. The critical number of stars at which gravothermal oscillations first appeared is found using a gas code. The nature of the oscillations is investigated and it is shown that the oscillations can be understood by focusing on the behaviour of the heavier component, because of mass segregation. It is argued that, during each oscillation, the re-collapse of the cluster begins at larger radii while the core is still expanding. This re-collapse can halt and reverse a gravothermally driven expansion. This material outside the core contracts because it is losing energy both to the cool expanding core and to the material at larger radii. The core collapse times for each model are also found and discussed. For an appropriately chosen case, direct N -body runs were carried out, in order to check the results obtained from the gas model, including evidence of the gravothermal nature of the oscillations and the temperature inversion that drives the expansion.

States and territories across North America are enacting and enforcing an increasing number of policies to fight climate change, mandating utilities to replace fossil-fueled generation with renewable energy resources (RERs) to achieve grid decarbonization. While RERs will help move toward a decarbonized power system, the inclusion of vast quantities of these resources coupled with an expanding threat landscape poses several reliability and resilience challenges to power system planners due to their variability and intermittency. Energy storage systems (ESS) can alleviate some of these challenges posed by the RERs and threats. However, there still exists significant barriers in modeling, integrating, and deploying ESSs to support reliability, resilience, and grid decarbonization. This panel will discuss the best practices, state-of-the-art approaches, and key challenges to the planning and operations of the grid with ESS, including critical topics such as planning for resilience, reliability, recovery, enhanced resource adequacy, and capacity accreditation techniques.

description: Structured light, which exhibits nontrivial intensity, phase, and polarization patterns in space, has key applications ranging from imaging and 3D micromanipulation to classical and quantum communication. However, to date, its application to molecular chirality has been limited by the weakness of magnetic interactions. Here we structure light’s local handedness in space to introduce and realize an enantio-sensitive interferometer for efficient chiral recognition without magnetic interactions, which can be seen as an enantio-sensitive version of Young’s double slit experiment. Upon interaction with isotropic chiral media, such chirality-structured light effectively creates chiral emitters of opposite handedness, located at different positions in space. We show that if the distribution of light’s handedness breaks left-right symmetry, the interference of these chiral emitters leads to unidirectional bending of the emitted light, in opposite directions in media of opposite handedness, even if the number of the left-handed and right-handed emitters excited in the medium is exactly the same. Our work introduces the concepts of polarization of chirality and chirality-polarized light, exposes the immense potential of sculpting light’s local chirality, and offers novel opportunities for efficient chiral discrimination, enantio-sensitive optical molecular fingerprinting and imaging on ultrafast time scales.

description: There are three subtypes of the β-adrenoceptors (β1, β2 and β3). All the β-adrenoceptor subtypes couple to Gαs subunit of G protein. All the β-adrenoceptor subtypes couple mainly to Gαs subunit of G protein. β2-adrenoceptor agonists have been used clinically to suppress myometrial contractions during the management of preterm labour. β2-adrenoceptor agonists lose their effectiveness in a short time and their use causes several side effects. Evidence in the literature supports the expression of functional β2- and β3-adrenoceptors in the lower pregnant human myometrial tissues. However, no definitive understanding in terms of regional and temporal expression and function of the β-adrenoceptors in the uterus was obtained by reviewing the literature. Experiments of this work have confirmed the expression of the three β-adrenoceptor subtypes in term pregnant (upper and lower) human myometrial tissues by real-time RT-PCR analysis. Poor antibody specificity was an obstacle to determine and localize the β-adrenoceptor proteins in the myometrium by immunohistochemistry. β2- and β3-adrenoceptor agonists did not affect the expression of CRISPLD2, RGS2 and NA4A3 in primary MSM cells after 2 and 6 h of incubation. Further research must be done to determine and localize the expression of the β-adrenoceptors in the myometrium.

description: This paper considers the multi-way relay channel (MWRC) where multiple users exchange messages via a single relay. The capacity region is derived for a special class of MWRCs where (i) the uplink and the downlink are separated in the sense that there is no direct user-to-user links, (ii) the channel is restricted in the sense that each user's transmitted channel symbols can depend on only its own message, but not on its received channel symbols, and (iii) the uplink is any deterministic function.

description: Global-scale quantum communication links will form the backbone of the quantum internet. However, exponential loss in optical fibres precludes any realistic application beyond few hundred kilometres. Quantum repeaters and space-based systems offer solutions to overcome this limitation. Here, we analyse the use of quantum memory (QM)-equipped satellites for quantum communication focussing on global range repeaters and memory-assisted (MA-) QKD, where QMs help increase the key rate by synchronising otherwise probabilistic detection events. We demonstrate that satellites equipped with QMs provide three orders of magnitude faster entanglement distribution rates than existing protocols based on fibre-based repeaters or space systems without QMs. We analyse how entanglement distribution performance depends on memory characteristics, determine benchmarks to assess the performance of different tasks and propose various architectures for light-matter interfaces. Our work provides a roadmap to realise unconditionally secure quantum communications over global distances with near-term technologies.

description: Cache attacks allow attackers to infer the properties of a secret execution by observing cache hits and misses. But how much information can actually leak through such attacks? For a given program, a cache model, and an input, our CHALICE framework leverages symbolic execution to compute the amount of information that can possibly leak through cache attacks. At the core of CHALICE is a novel approach to quantify information leakage that can highlight critical cache side-channel leakage on arbitrary binary code. In our evaluation on real-world programs from OpenSSL and Linux GDK libraries, CHALICE effectively quantifies information leakage: For an AES-128 implementation on Linux, for instance, CHALICE finds that a cache attack can leak as much as 127 out of 128 bits of the encryption key.

description: Die Implementierung eines Recommendersystems (Empfehlungsdienstes) zur Besucherlenkung erfordert die Analyse möglicher Touchpoints, die eine größtmögliche Reichweite für eine effektive Kommunikation der Recommender im Sinne einer nachhaltigkeitsorientierten Besucherlenkung schaffen. Touchpoints lassen sich entlang der touristischen Customer Journey verorten (z.B. im Zuge der Informationssuche oder während der Reise selbst), wobei sich hier die Frage stellt, in welcher Phase der größte Nutzen im Kontext einer effektiven Besucherlenkung geschaffen werden kann.
 Ziel dieses Kurzberichts ist es, eine Grundlage zu schaffen, wie ein Recommendersystem zur Besucherlenkung im Rahmen eines effektiven Touchpointmanagements implementiert werden kann. Basierend darauf soll ein Werkzeugkasten entwickelt werden, der in Zusammenspiel mit identifizierten Touchpoints verschiedene Interventionen der Besucherlenkung beinhaltet, die auf die unterschiedlichen Use Cases angewendet werden können. Für das AIR-Projekt können diese Interventionen in unterschiedlichen touristischen Kontexten eingesetzt und auf deren Effektivität zur Besucherlenkung evaluiert werden.

Creators: name: Wang, Cheng
Publisher: name: Memorial University of Newfoundland
Year: 2019

description: This thesis mainly deals with the synthesis and characterization of arenebased
 π-conjugated systems. The content can be divided into three major
 parts. In the first section, a series of tetraaryl-anthraquinodimethane derivatives
 (Ar₄-AQs) was synthesized via Suzuki coupling reactions, and these compounds
 were subjected to intramolecular cyclization reactions under chemical and
 photochemical conditions with the aim of making highly π-delocalized polycyclic
 aromatic hydrocarbons (PAHs). The Ar₄-AQs and their cyclized products were
 investigated by various spectroscopic analyses, including NMR, UV-Vis absorption
 spectroscopy, and X-ray crystallography to understand their structural, electronic,
 and photochemical properties. In the second part, microporous organic cross-linked
 polymer networks were successfully prepared from Schiff base condensation of a
 tetrabis(carboxaldehyde)-substituted Ar₄-AQ and para-phenylenediamine. Under
 optimized conditions, the resulting microporous organic materials showed good
 microporosity and crystallinity. In the third section, the detailed reaction mechanisms
 of intramolecular alkyne-dithiolium [3+2] cycloaddition reactions were investigated
 by a joint experimental and theoretical approach. A number of alkynyl-subsituted
 phenyldithiafulvenes was prepared as model compounds. Density functional theory
 (DFT) calculations were performed to reveal the effects of pH and degree of π-
 conjugation on reactivity.

description: Background: The objectives of this thesis were to describe the impacts of drug-related street disorder on street-based injection drug users (IDU) in Vancouver, Canada and to explore the potential impacts of three policy interventions (low-threshold supportive housing, low-threshold employment, and supervised inhalation facilities) on the reduction of street disorder. Methods: Data for these studies were derived from the Vancouver Injection Drug Users Study (VIDUS) which is a community recruited prospective cohort of IDU. Study participants were invited on bi-annual bases to complete an interviewer-administered questionnaire. Various multivariate regression techniques were utilized to assess factors associated with exposure to drug-related street disorder, socializing in Vancouver’s open drug scene, engaging in disorderly income generation activities, and smoking crack cocaine in public areas. Further multivariate analyses were conducted to assess willingness to reduce engagement in behaviours that contribute to drug-related street disorder. Results: At baseline, 21% of the study sample reported spending over 15 hour per day in Vancouver’s open drug scene on average. Drug scene exposure was found to be associated in a dose-dependent fashion with higher intensity drug use and multiple markers of vulnerability to adverse health outcomes. In further analyses, 43% of participants reported socializing in the open drug scene for 3 or more hours per day, and having limited access to private space was the factor most strongly associated with this behaviour. Among this group 65% reported being willing to relocate if given access to more private space. 47% of participants who engaged in disorderly income generation activities were willing to forgo these income sources if given low-threshold employment, and 71% of crack cocaine smokers who reported recently using in public areas were willing to visit a supervised inhalation facility. Conclusions: These studies highlight the importance of viewing street disorder in the context of current political, economic, and social conditions and provide a compelling body of evidence indicating that structural and environmental level interventions, specifically in the areas of housing (i.e., provision of private space), employment and supervised drug consumption facilities, are likely to have a positive influence on public health and reduce engagement in drug-related street disorder.

description: Absolute cross sections for the K-shell photoionization of ground-state Li-like carbon [C$^{3+}$(1s$^2$2s $^2$S)] ions were measured by employing the ion-photon merged-beams technique at the Advanced Light Source. The energy ranges 299.8--300.15 eV, 303.29--303.58 eV and 335.61--337.57 eV of the [1s(2s2p)$^3$P]$^2$P, [1s(2s2p)$^1$P]$^2$P and [(1s2s)$^3$S 3p]$^2$P resonances, respectively, were investigated using resolving powers of up to 6000. The autoionization linewidth of the [1s(2s2p)$^1$P]$^2$P resonance was measured to be $27 \pm 5$ meV and compares favourably with a theoretical result of 26 meV obtained from the intermediate coupling R-Matrix method. The present photoionization cross section results are compared with the outcome from photorecombination measurements by employing the principle of detailed balance.

Wildfires have become the Achilles' heel of modern power infrastructure prone to this emerging hazard despite significant investments made in resilience building measures during recent years. The power grid infrastructure can be affected by, and contribute to, wildfires. A deep defense strategy consisting of three lines of defense can be adopted to effectively manage the risk of wildfires in electric power infrastructure. The first line of defense focuses on strategies to prevent wildfires from occurring in the first place. Recognizing that the first line of defense may not always hold, the second line of defense is focused on mitigation strategies and proactive response, should a wildfire spark. Finally, if a wildfire sparks and spreads despite all the defensive measures in the first two lines, we need a third line of defense that is focused on resilience-building measures and recovery preparedness so the system can bounce back to its pre-wildfire condition as quickly as possible without suffering devastating losses. This panel will explore solutions from different perspectives including a) power and utilities industry, b) forest management and environmental stewardship, c) engineering research and development, and d) energy economics and policy.

description: Rapid orbital drift of macroscopic dust particles is one of the major obstacles against planetesimal formation in protoplanetary disks. We reexamine this problem by considering porosity evolution of dust aggregates. We apply a porosity model based on recent N-body simulations of aggregate collisions, which allows us to study the porosity change upon collision for a wide range of impact energies. As a first step, we neglect collisional fragmentation and instead focus on dust evolution outside the snow line, where the fragmentation has been suggested to be less significant than inside the snow line because of a high sticking efficiency of icy particles. We show that dust particles can evolve into highly porous aggregates (with internal densities of much less than 0.1 g/cm^3) even if collisional compression is taken into account. We also show that the high porosity triggers significant acceleration in collisional growth. This acceleration is a natural consequence of particles' aerodynamical property at low Knudsen numbers, i.e., at particle radii larger than the mean free path of the gas molecules. Thanks to this rapid growth, the highly porous aggregates are found to overcome the radial drift barrier at orbital radii less than 10 AU (assuming the minimum-mass solar nebula model). This suggests that, if collisional fragmentation is truly insignificant, formation of icy planetesimals is possible via direct collisional growth of submicron-sized icy particles.

Secure authentication in the grid: A formal analysis of DNP3 SAv5

description: Most of the world's power grids are controlled remotely. Their control messages are sent over potentially insecure channels, driving the need for an authentication mechanism. The main communication mechanism for power grids and other utilities is defined by an IEEE standard, referred to as DNP3; this includes the Secure Authentication v5 (SAv5) protocol, which aims to ensure that messages are authenticated. We provide the first security analysis of the complete DNP3: SAv5 protocol. Previous work has considered the message-passing sub-protocol of SAv5 in isolation, and considered some aspects of the intended security properties. In contrast, we formally model and analyse the complex composition of the protocol's sub-protocols. In doing so, we consider the full state machine, the protocol's asymmetric mode, and the possibility of cross-protocol attacks. Furthermore, we model fine-grained security properties that closely match the standard's intended security properties. For our analysis, we leverage the Tamarin prover for the symbolic analysis of security protocols. Our analysis shows that the core DNP3: SAv5 design meets its intended security properties. Notably, we show that a previously reported attack does not apply to the standard. However, our analysis also leads to several concrete recommendations for improving future versions of the standard.
