description: Let $G$ be a Lie group and $M$ a smooth proper $G$-manifold. Let $pi:Mto M/G$ denote the natural map to the orbit space. Then there exist a PL manifold $P$, a polyhedron $L$ and homeomorphisms $tau:Pto M$ and $σ:M/Gto L$ such that $σ\circpi\circτ$ is PL. If $M$ and the $G$-action are of analytic class, we can choose subanalytic $τ$ and then unique $P$ and $L$.

The cell autonomous and cell non-automous roles of YAP1 during pancreatogenesis
Creators: name: Wang, Shihao
Publisher: name: University of British Columbia
Year: 2023

description: The HIPPO signaling pathway is highly conserved and affects organ development specifically through cellular differentiation and proliferation. Yes-associated protein 1 (YAP1) is a downstream effector of the HIPPO signaling pathway that controls the transcription of a number of secreted factors and cell-to-cell signalling pathways. Although many downstream targets of YAP1 were known to be secreted factors, the observation that YAP1 acts via cell autonomous and non-cell autonomous mechanisms has only recently been described. Given that an active form of YAP1 has been shown to block differentiation of pancreatic progenitor cells during development, we characterized whether these effects involved cell autonomous or cell non-autonomous signalling. To understand the cell autonomous and cell non-autonomous function of YAP1, we utilized loss and gain of function approaches and lineage tracing tools to examine the role of YAP1 during progenitor cell differentiation, as well as its potential impact on other cell types in the pancreas. Our animal model allowed us to manipulate the pancreatic progenitor cells in a mosaic manner. I found that maintaining YAP1 activation cell autonomously blocks the differentiation of both bipotent progenitor and acinar progenitor cells during pancreas development. I also found that progenitor cells not expressing active YAP1 non-cell autonomously acquired the acinar and endocrine cells fate. We also examined functionally whether YAP1-expressing bipotent progenitor and acinar progenitor cells could differentiate outside their normal differentiation window. In addition, our data indicated that YAP1 activity in pancreatic progenitor cells non-cell autonomously regulated the mesenchymal population and the remodeling of the vascular system. These findings revealed a cell autonomous and non-cell autonomous function of YAP1 in the developing pancreatic epithelium and uncovered a YAP1-mediated three-way regulatory interaction between progenitor epithelium, mesenchyme and the vasculature during pancreas development.

В ходе нашего исследования эмпирически было доказано, что тренинг образной саморегуляции эффективен в работе со студентами, которые испытывают тревогу перед ситуацией предстоящего экзамена. В процессе проведения тренинга в экспериментальной группе было доказано, что достоверно снизился показатель реактивной тревожности(характеризуется беспокойством, напряжением, нервозностью в конкретный момент или интервал времени). Тренинг образной саморегуляции способен поддерживать положительное, относительно стабильное состояние испытуемых в процессе оказания психологической помощи
description: We are conducting a study of the effectiveness of figurative self-regulation training. This experiment took place in two groups: experimental and control. In the course of our study, it was empirically proven that figurative self-regulation training is effective in working with students who are anxious about the situation of the upcoming exam. During the training in the experimental group, it was proved that the indicator of reactive anxiety (characterized by anxiety, tension, nervousness at a particular moment or time interval) significantly decreased. Training of figurative self-regulation is able to maintain a positive, relatively stable state of the subjects in the process of providing psychological assistance

description: The integration of Near Field Communication (NFC) and Radio Frequency Identification (RFID) systems on the Internet of Things (IoT) has become increasingly prevalent in various sectors, from residential automation to government institutions and healthcare facilities. However, this proliferation has raised concerns about individual security and privacy. 
This thesis focuses on identifying and addressing vulnerabilities in NFC and RFID systems, specifically mitigating eavesdropping and replay attacks. Our proposed solution centers on developing a hardware-encrypted Printed Circuit Board (PCB) to prevent these attacks at their source. The PCB integrates several components, including AES-128 encryption, a secure element chip, and the dynamic power of accelerometers. Our proposed approach harnesses the potential of accelerometers for generating dynamic cryptographic keys, which, when combined with secure elements for key storage, represent a formidable defense against attack vectors such as eavesdropping and replay attacks. Our method has a 17.8 μs average encryption time and 9.3 μs average key generation time. It successfully mitigated 35 out of 37 real-world scenario relay attacks.
The proposed solution is indispensable in elevating the security framework of NFC/RFID systems. It mitigates vulnerabilities and champions the cause of security, integrity, and privacy, enhancing the trustworthiness of our everyday technological interactions and fortifying our digital lives.

description: Monte Carlo simulations and finite-size scaling analysis have been carried out to study the critical behavior in a two-dimensional system of particles with two bonding sites that, by decreasing temperature or increasing density, polymerize reversibly into chains with discrete orientational degrees of freedom and, at the same time, undergo a continuous isotropic-nematic (IN) transition. A complete phase diagram was obtained as a function of temperature and density. The numerical results were compared with mean field (MF) and real space renormalization group (RSRG) analytical predictions about the IN transformation. While the RSRG approach supports the continuous nature of the transition, the MF solution predicts a first-order transition line and a tricritical point, at variance with the simulation results.

Grain sedimentation inside giant planet embryos

description: In the context of massive fragmenting protoplanetary discs, Boss (1998) suggested that grains can grow and sediment inside giant planet embryos formed at R ~ 5 AU away from the star. Several authors since then criticised the suggestion. Convection may prevent grain sedimentation, and the embryos cannot even form so close to the parent star as cooling is too inefficient at these distances. Here we reconsider the grain sedimentation process suggested by Boss (1998) but inside an embryo formed, as expected in the light of the cooling constraints, at R ~ 100 AU. Such embryos are much less dense and are also cooler. We make analytical estimates of the process and also perform simple spherically symmetric radiation hydrodynamics simulations to test these ideas. We find that convection in our models does not become important before a somewhat massive (~ an Earth mass, this is clarified in a followup paper) solid core is built. Turbulent mixing slows down dust sedimentation but is overwhelmed by grain sedimentation when the latter grow to a centimetres size. The minimum time required for dust sedimentation to occur is a few thousand years, and is a strong function of the embryo's mass, dust content and opacity. An approximate analytical criterion is given to delineate conditions in which a giant embryo contracts and heats up faster than dust can sediment. As Boss et al (2002), we argue that core formation through grain sedimentation inside the giant planet embryos may yield an unexplored route to form giant gas and giant ice planets. The present model also stands at the basis of paper III, where we study the possibility of forming terrestrial planet cores by tidal disruption and photoevaporation of the planetary envelope.

description: Analysis of data without labels is commonly subject to scrutiny by unsupervised machine learning techniques. Such techniques provide more meaningful representations, useful for better understanding of a problem at hand, than by looking only at the data itself. Although abundant expert knowledge exists in many areas where unlabelled data is examined, such knowledge is rarely incorporated into automatic analysis. Incorporation of expert knowledge is frequently a matter of combining multiple data sources from disparate hypothetical spaces. In cases where such spaces belong to different data types, this task becomes even more challenging. In this paper we present a novel immune-inspired method that enables the fusion of such disparate types of data for a specific set of problems. We show that our method provides a better visual understanding of one hypothetical space with the help of data from another hypothetical space. We believe that our model has implications for the field of exploratory data analysis and knowledge discovery.

description: We have created synthetic neutral hydrogen (HI) Galactic Plane Survey data cubes covering 90 degrees < l < 180 degrees, using a model spiral galaxy from SPH simulations and the radiative transfer code TORUS. The density, temperature and other physical parameters are fed from the SPH simulation into TORUS, where the HI emissivity and opacity are calculated before the 21-cm line emission profile is determined. Our main focus is the observation of Outer Galaxy `Perseus Arm' HI, with a view to tracing atomic gas as it encounters shock motions as it enters a spiral arm interface, an early step in the formation of molecular clouds. The observation of HI self-absorption features at these shock sites (in both real observations and our synthetic data) allows us to investigate further the connection between cold atomic gas and the onset of molecular cloud formation.

description: Cooperation is of utmost importance to society as a whole, but is often challenged by individual self-interests. While game theory has studied this problem extensively, there is little work on interactions within and across groups with different preferences or beliefs. Yet, people from different social or cultural backgrounds often meet and interact. This can yield conflict, since behavior that is considered cooperative by one population might be perceived as non-cooperative from the viewpoint of another. To understand the dynamics and outcome of the competitive interactions within and between groups, we study game-dynamical replicator equations for multiple populations with incompatible interests and different power (be this due to different population sizes, material resources, social capital, or other factors). These equations allow us to address various important questions: For example, can cooperation in the prisoner's dilemma be promoted, when two interacting groups have different preferences? Under what conditions can costly punishment, or other mechanisms, foster the evolution of norms? When does cooperation fail, leading to antagonistic behavior, conflict, or even revolutions? And what incentives are needed to reach peaceful agreements between groups with conflicting interests? Our detailed quantitative analysis reveals a large variety of interesting results, which are relevant for society, law and economics, and have implications for the evolution of language and culture as well.

description: We extend the previously observed scaling equation connecting the internode distances and nodes' degrees onto the case of weighted networks. We show that the scaling takes a similar form in the empirical data obtained from networks characterized by different relations between node's strength and its degree. In the case of explicit equation for s(k) (e.g. linear or scale-free), the new coefficients of scaling equation can be easily obtained. We support our analysis with numerical simulations for Erdos-Renyi random graphs with different weight distributions.

description: Giant planet embryos are believed to be spawned by gravitational instability in massive extended (R ~ 100 AU) protostellar discs. In a recent paper we have shown that dust can sediment inside the embryos, as argued earlier by Boss (1998) in a slightly different model. Here we study numerically the next stage of this process -- the formation of a solid core. If conditions are conducive to solid core formation, the centre of the gas cloud goes through the following sequence of phases: (i) becomes grain (and metal) rich; (ii) forms a terrestrial mass solid core via a rapid collapse driven by self-gravity of the grains; (iii) starts to accrete a gaseous atmosphere when the solid core reaches mass of a few to 10 Earth masses. This sequence of events may build either terrestrial planet cores or metal rich giant planets inside the larger gas reservoir of the giant planet embryo. In a companion Letter we argue that tidal and irradiation effects from the parent star should disrupt the outer metal poor layers of the embryo, releasing nearly "ready to use" planets. We propose this as an alternative way to build planets.

description: In Ethereum blockchain, smart contracts are immutable, public, and distributed. However, they are subject to many vulnerabilities stemming from coding errors made by developers. Seven cybersecurity incidents occurred in Ethereum smart contracts between 2016 and 2018, which led to financial losses estimated to be over US$ 289 million. Reentrancy vulnerability was the cause of two of these incidents, and the impacts went far beyond financial loss. Several reentrancy countermeasures are available, which are based on predefined patterns that are used to prevent vulnerability exploitation before the deployment of a smart contract; however, several limitations have been identified in these countermeasures. Motivated by all these issues, the objective of this article is to help developers improve the cybersecurity of smart contracts by proposing a solution that calculates the difference between the contract balance and the total balance of all participants in a smart contract before and after any operation in a transaction that changes its state. Proof-of-concept implementations show that this solution can provide a detection and prevention mechanism against reentrancy attacks during the execution of any smart contract.

description: We study the correlation of the velocity dispersion of the coexisting molecules H13CN and H13CO+ and the turbulent energy dissipation scale in the DR21(OH) star-forming region. The down-shift of the H13CO+ spectrum relative to H13CN is consistent with the presence of ambipolar diffusion at dissipation length scales that helps the process of turbulent energy dissipation, but at a different cut-off for ions compared to the neutrals. We use our observational data to calculate a turbulent ambipolar diffusion length scale L'\simeq17 mpc and a strength of B_{pos}\simeq1.7 mG for the plane of the sky component of the magnetic field in DR21(OH).

description: We analyze the collider signals of composite scalars that emerge in certain little Higgs models and models of vectorlike confinement. Similar to the decay of the pion into photon pairs, these scalars mainly decay through anomaly-induced interactions into electroweak gauge bosons, leading to a distinct signal with three or more photons in the final state. We study the standard model backgrounds for these signals, and find that the LHC can discover these models over a large range of parameter space with 30 fb$^{-1}$ at 14 TeV. An early discovery at the current 7 TeV run is possible in some regions of parameter space. We also discuss possibilities to measure the spin of the particles in the $γγ$ and $Zγ$ decay channels.

description: Target engagement assays detect and quantify the direct physical interaction of a protein of interest and its ligand, typically done by measuring subtle changes in a target protein’s stability induced upon ligand binding. To perturb protein stability, an external stressor is typically applied. Commonly used target engagement methods detect ligand-induced stability by subjecting samples to thermal or proteolytic stress. Current techniques often use slow-growing and expensive cell lines, exogenous visualizing agents, or exceptionally pure protein samples. Conventional target engagement techniques are useful but expensive and have low throughput. Here we describe three variations of target engagement that utilize robust prokaryotic expression systems, internal fluorescent probes, and alternative methods to measure target stability all with minimal sample manipulation. Prokaryotic Lysate–Thermal Shift Assay (ProLys-TSA) detects the melting behavior of target proteins using an internal fluorescent reporter across a temperature range in E. coli lysates. GFP-PRMT1 constructs treated with SAH cofactor and inhibitor EPZ020411 were used to validate ProLys-TSA. Isothermal Ligand-induced Resolubilization Assay (ILIRA) utilizes lyotropic solubility stress to measure target engagement through changes in target protein solubility. ILIRA was validated using 4 target proteins and inhibitor pairings: PRMT1 with SAH cofactor and MS023, DHFR with pyrimethamine, NUDT5 with TH5427, and PARP1 with olaparib. Ligand Inclusion Body Rescue-Target Engagement Assay (LIBR-TEA) utilizes the polar aprotic solvent DMSO to cause protein solubility stress in whole-cell E. coli samples. Fluorescent measurements of recombinant GFP-PRMT1 expressed in E. coli cells treated with MS023 were the basis of measurement. Stress methods used in the described assays can be classified as: lyotropic stress, solvent stress and thermal stress. Internal GFP reporters provide a direct quantification of soluble state protein. Preliminary results suggest that all three stressors chosen were able to destabilize target proteins, decreasing soluble protein levels regardless of measurement method. After addition of target-specific cofactor or small molecule inhibitor, statistically significant increases in soluble protein were observed in all three assay types. ILIRA represents our most developed assay concept. Initial data obtained suggest all three methods have potential to be further developed into robust target engagement assays, representing novel contributions to the field.

description: We present a general mapping between continuous and lattice models of Bose- and Fermi-gases in one dimension, interacting via local two-body interactions. For s-wave interacting bosons we arrive at the Bose-Hubbard model in the weakly interacting, low density regime. The dual problem of p-wave interacting fermions is mapped to the spin-1/2 XXZ model close to the critical point in the highly polarized regime. The mappings are shown to be optimal in the sense that they produce the least error possible for a given discretization length. As an application we examine the ground state of a interacting Fermi gas in a harmonic trap, calculating numerically real-space and momentum-space distributions as well as two-particle correlations. In the analytically known limits the convergence of the results of the lattice model to the continuous one is shown.

description: Much recent interest has focused on "open" dynamical systems, in which a classical map or flow is considered only until the trajectory reaches a "hole", at which the dynamics is no longer considered. Here we consider questions pertaining to the survival probability as a function of time, given an initial measure on phase space. We focus on the case of billiard dynamics, namely that of a point particle moving with constant velocity except for mirror-like reflections at the boundary, and give a number of recent results, physical applications and open problems.

Machine learning applied for contaminant detection in natural surface water

description: Approximately 1.4 billion m³ of fluid tailings produced from oil sands mining operations are currently being held in Alberta, Canada and pose a significant risk to the environment if not properly treated and managed. The ability to quantify levels of toxic compounds present in oil sands tailings, such as naphthenic acids (NAs), phenol, and polycyclic aromatic hydrocarbons (PAHs), is required to ensure the protection of the surrounding aquatic environment. In this thesis, machine learning techniques are applied to rapidly detect toxic contaminants from the production of petroleum products and crude oil extraction in natural surface waters. The first study implemented modern neural network structures for improving supervised regression of NA and phenol concentrations in water. Multilayer perceptron (MLP) and convolutional neural networks (CNN) were both capable of identifying relevant spectral features of the pollutants and were accurate in estimating concentrations in the presence of background interference from organic matter in natural waters. NAs were relatively easy to detect by MLP and CNN, however, deep CNNs resulted in optimized performance for phenol with mean absolute errors (MAE) of 1.78 – 1.81 mg/L and 4.68 - 5.41 µg/L for NAs and phenol, respectively. Visualization of spectral areas of importance revealed that both MLPs and deep CNNs utilized logical regions of the fluorescence spectra associated with NAs and phenol signals. The second study aimed to improve available methods for in situ quantification of NA, phenol, pyrene, and fluoranthene concentrations in natural waters. An augmentation network that fuses data from field and lab-based optical measures was used to improve the quality of field measurements. NAs, fluoranthene and pyrene were easy to quantify by the augmentation network, however, performance for phenol was more challenging due to the low intensity of the signal and overlap with other more dominant signals from NAs. Detection and quantification of phenol was optimized by the augmentation network proposed compared to standard in situ methods such peak-picking (peak-picking MAE of 30.48 µg/L, augmentation network MAE of 8.30 µg/L). Finally, an unsupervised approach to detecting pollutants in water was investigated, where no knowledge of contaminant levels is needed to train the model. A variational autoencoder was used to reduce data dimensionality and, through unsupervised methods, NAs and phenol could be identified in natural surface waters. According to the unsupervised classification methods, water samples contaminated with only NAs had the highest accuracy scores. The model classified water samples contaminated with NAs and phenol as if they were only contaminated with NAs, since NAs signals overshadowed phenol signals.

description: A large repertoire of spatiotemporal activity patterns in the brain is the basis for adaptive behaviour. Understanding the mechanism by which the brain's hundred billion neurons and hundred trillion synapses manage to produce such a range of cortical configurations in a flexible manner remains a fundamental problem in neuroscience. One plausible solution is the involvement of universal mechanisms of emergent complex phenomena evident in dynamical systems poised near a critical point of a second-order phase transition. We review recent theoretical and empirical results supporting the notion that the brain is naturally poised near criticality, as well as its implications for better understanding of the brain.

description: The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is discovering a large number of new hard X-ray sources, many of them being HMXBs. The identification and spectral characterization of their optical/infrared counterparts is a necessary step in undertaking a detailed study of these systems. In a previous paper, we presented spectral analyses and classifications of six newly discovered INTEGRAL sources. In this paper, we extend the analysis to IGR J16493-4348. We used the ESO/VLT ISAAC spectrograph to observe the proposed IR counterpart to the source, obtaining a Ks medium-resolution spectrum (R = 500) with a signal-to-noise ratio (S/N) >150. We classified the source by comparing with published atlases. We spectrally classified the source as a B0.5-1 supergiant and estimated its interstellar extinction. We compared the extinction derived from X-ray data with effective interstellar extinction obtained from our data, discussing the absorption component associated with the circumstellar environment.

description: The stochastic dynamics of heavy quarks in the fireball produced in heavy-ion collisions is followed through numerical simulations based on the Langevin equation. The modification of the final p_T spectra (R_AA) of c and b quarks, hadrons and single-electrons with respect to pp collisions is studied. The transport coefficients are evaluated treating separately the contribution of soft and hard collisions. The initial heavy-quark spectra are generated according to NLO-pQCD, accounting for nuclear effects through recent nPDFs. The evolution of the medium is obtained from the output of two hydro-codes (ideal and viscous). The heavy-quark fragmentation into hadrons and their final semileptonic decays are implemented according to up to date experimental data. A comparison with RHIC data for non-photonic electron spectra is given.
