Ligand transduction mechanisms of inwardly-rectifying potassium channels
Creators: name: Li, Bowen
Publisher: name: University of British Columbia
Year: 2013

description: Regulation of inwardly-rectifying potassium (Kir) channels by intracellular ligands couples cell membrane excitability to important signaling cascades and metabolic pathways. Particularly, the ATP-sensitive potassium (KATP) channels, highly expressed in diverse excitable tissues, are the keystone components of glucose-stimulated insulin secretion in pancreatic β-cells. KATP channels are constituted by a canonical pore-forming transmembrane domain (TMD) and a large cytoplasmic domain (CTD) where ATP binds and inhibits the channel activity. A non-covalent interface domain in Kir channel structures is speculated as a mediator of coupling between the cytoplasmic (‘ligand-sensing’) and transmembrane (‘gating’) domains. The work described in this thesis aims to investigate the molecular mechanism that link ligand binding to the channel gating. A significant barrier is that many functionally important channel motifs are highly sensitive to mutagenesis, resulting in a loss-of-function (LOF) phenotype. We have developed a novel ‘forced gating’ approach by substituting a glutamate in the hydrophobic Kir channel bundle crossing (F168E), generating channels that open upon alkalization, likely due to mutual repulsion of the introduced glutamate side chain. This ‘forced gating’ approach is implemented in mutagenic scans of the Kir channel domain interface comprising numerous motifs, including the transverse ‘slide’ helix, the C-linker, the βC-βD loop, and the G-loop. Without exception, expression on the ‘forced gating’ background rescued all loss-of-function interfacial mutants in alkaline pH, and enabled functional characterization of all interfacial mutants on generation of conductive channels and ATP-dependent gating. Our findings highlight a small subset of ‘anchor residues’ at the Kir6.2 TMD-CTD interface, including D58 and T61 in the ‘slide helix’, R177 in the C-linker, T294 in the G-loop, and D204 in the βC-βD loop, which are required for both formation of conductive channels, and appropriate transmission of ligand binding to the channel gating. Disruption of these residues uncouples the TMD and CTD, causing loss-of-function phenotype combined with profound ligand insensitivity. Additionally, in contrast to a traditional ‘allosteric rescue’ approach (Kir6.2[C166S]) with an elevated intrinsic channel open probability, the ‘forced gating’ approach has a more general application due to its efficiency in rescuing all loss-of-function interfacial mutants without inherently perturbing ATP sensitivity in Kir6.2 channel.

description: Markov Chain Monte Carlo (MCMC) methods, such as the Metropolis-Hastings (MH) algorithm, are widely used for Bayesian inference. One of the most important issues for any MCMC method is the convergence of the Markov chain, which depends crucially on a suitable choice of the proposal density. Adaptive Rejection Metropolis Sampling (ARMS) is a well-known MH scheme that generates samples from one-dimensional target densities making use of adaptive piecewise proposals constructed using support points taken from rejected samples. In this work we pinpoint a crucial drawback in the adaptive procedure in ARMS: support points might never be added inside regions where the proposal is below the target. When this happens in many regions it leads to a poor performance of ARMS, with the proposal never converging to the target. In order to overcome this limitation we propose two improved adaptive schemes for constructing the proposal. The first one is a direct modification of the ARMS procedure that incorporates support points inside regions where the proposal is below the target, while satisfying the diminishing adaptation property, one of the required conditions to assure the convergence of the Markov chain. The second one is an adaptive independent MH algorithm with the ability to learn from all previous samples except for the current state of the chain, thus also guaranteeing the convergence to the invariant density. These two new schemes improve the adaptive strategy of ARMS, thus simplifying the complexity in the construction of the proposals. Numerical results show that the new techniques provide better performance w.r.t. the standard ARMS.

description: In this article, simulation results are presented for an extreme adaptive optics (order 200x200 sub-apertures) system, using a Pyramid WFS. These end-to-end simulations show that such a system is tractable with current simulation software and hardware. We also demonstrate that a novel reconstruction algorithm – CuRe – can provide similar performance (at much lower computational cost) than our standard Matrix Vector Multiply.

description: SPHERE is an extra-solar planet imager instrument for ESO's VLT telescope. Scheduled for first light in 2012, aims to detect giant extra-solar planet in the vicinity of bright stars and to characterise the objects found through spectroscopic and polarimetric observations. The observations will be done both within the Y, J, H and Ks atmospheric windows (~0.95 – 2.32μm) by the aid of a dual imaging camera (IRDIS) and an integral field spectrograph (IFS), and in the visible using a fast-modulating polarizing camera (ZIMPOL). The instrument employs an extreme-AO turbulence compensation system, focal plane tip-tilt correction, and interferential coronagraphs. The aim of this paper is to analyse the approach taken for system analysis and implementation in the light of forthcoming instruments of this type to be design and built for ELT-class telescopes.

description: This paper discusses a simulation-based framework for laser guide star (LGS) point spread function
reconstruction (PSFR) for the Thirty Meter Telescope’s 1st-light multi-conjugate adaptive optics system NFIRAOS.
The approach is based on processing first the NFIRAOS on-axis LGS measurements to compute a tip/tiltremoved
(TTR) LGS structure function (SF) using V´eran’s method. This reconstructed LGS SF can then be used
to estimate the PSF in science directions as discussed in [Gilles et al., 2011] in this same conference.

description: We employ the methods of atomistic simulation to investigate the climb of edge dislocation at nanovoids by analyzing the energetics of the underlying mechanism. A novel simulation strategy has been demonstrated to estimate the release of surface energy of the nanovoid during the void induced climb. The curvature of the pinned dislocation segment is found to play a key role in mediating this unique mechanism of dislocation climb. Our study reveals that the kinetics of void-induced climb process is fundamentally distinct from the conventional diffusion-mediated climb.

description: We present the last results of our PSF reconstruction (PSF-R) project for the Keck-II and Gemini-
North AO systems in natural guide star mode. Our initial tests have shown that the most critical aspects of PSF-R
are the determination of the system static aberrations and the optical turbulence parameters, and we have set up a
specific observation campaign on the two systems to explore this. We demonstrate that deformable mirror based
seeing monitor works well, and 10% accuracy is easily obtained. Phase diversity has been demonstrated to work
on sky sources. Besides, residual phase stationarity is an important assumption in PSF-R, and we demonstrate
here that it is basically true. As a result of these tests and verifications, we have been able for the first time to
obtain a very good PSF reconstruction for the Keck-II system, in bright natural guide star mode.

description: We present a general theory about electron orbital motions in topological insulators. An in-plane electric field drives spin-up and spin-down electrons bending to opposite directions, and skipping orbital motions, a counterpart of the integer quantum Hall effect, are formed near the boundary of the sample. The accompanying Zitterbewegung can be found and controlled by tuning external electric fields. Ultrafast flipping electron spin leads to a quantum side jump in the topological insulator, and a snake-orbit motion in two-dimensional electron gas with spin-orbit interactions. This feature provides a way to control electron orbital motion by manipulating electron spin.

description: The Multi-threaded Adaptive Optics Simulator (MAOS) was developed at TMT to efficiently simulate
various kind of AO systems. In particular, it can finish a time step of full end-to-end simulation of an ELT
size multi-conjugate AO system in 1 second on 8 contemporary cpu cores. We recently ported it to run on graphical
processing units (GPUs) using the Nvidia CUDA technology. A 10 fold speed up is obtained with two GTX
580 GPUs, with each time step taking only 0.1 second. A single GPU can finish 30 iterations of the conjugate
gradients (CG) tomography algorithm in 30 ms, or 3 iterations of the fourier domain preconditional CG in 5 ms,
which is on the same order as the ~ 1ms requirement.

The nearest-neighbor tight-binding model was previously used to calculate plasmon spectrum in the next paper [1]. We expand the previous results of the paper by the next-nearest-neighbor tight-binding model. Both methods are based on the numerical calculation of the dielectric function of graphene and loss function. Here we compare plasmon spectrum of the next-nearest and nearest-neighbor tight-binding models and find differences between plasmon dispersion of two models.

description: We investigate from first-principles the change in transport properties of a two-dimensional azobenzene monolayer sandwiched between two Au electrodes that undergoes molecular switching. We focus on transport differences between a chemisorbed and physisorbed top monolayer-electrode contact. The conductance of the monolayer junction with a chemisorbed top contact is higher in trans configuration, in agreement with the previous theoretical predictions of one-dimensional single molecule junctions. However, with a physisorbed top contact, the "ON" state with larger conductance is associated with the cis configuration due to a reduced effective tunneling pathway by switching from trans to cis, which successfully explains recently experimental measurements of azobenzene monolayer junctions. A simple model is developed to explain electron transmission across subsystems in the molecular junction. We also discuss the effects of monolayer packing density, molecule tilt angle, and contact geometry on the calculated transmission functions. In particular, we find that a tip-like contact with chemisorption significantly affects the electric current through the cis monolayer, leading to highly asymmetric current-voltage characteristics as well as large negative differential resistance behavior.

description: We demonstrate experimentally that slicer based integral field spectrographs are an attractive
choice for the next generation of exoplanet direct detection instruments. By propagating a single simulated
speckle though a slicer based integral field spectrograph (IFS) and performing the post processing
technique of spectral deconvolution we are able to achieve a speckle rejection factor of ~600 in broadband
images (and ~100 in individual wavelength channels) with contrasts only appearing to be limited by
calibration errors in the IFS datacube. This is over an order of magnitude improvement on the current
state-of-the-art and well within the requirements of EPICS (Exo Planet Imaging Camera and Spectrograph
for the E-ELT) for post coronagraphic speckle rejection thus proving that slicers will not impose a limit on
the achievable contrast. When using prior knowledge of the diffraction-limited size of real objects we
further improve the speckle rejection factor such that it exceeds 10e3.

description: This paper discusses a simulation-based approach for long exposure point spread function reconstruction (PSFR)
for laser guide star (LGS) multi conjugate adaptive optics (MCAO). The approach is based on (i) processing the on-axis highorder
LGS wavefront sensor (WFS) second-order statistics to compute via simulation a tip/tilt removed (TTR) structure
function (SF) for the science target at infinite range, and (ii) processing similarly the multiple low-order natural guide star
(NGS) WFSs controlling tip/tilt (TT) and tilt anisoplanatism (TA) over an extended field of view (FoV) to compute via
simulation a tip/tilt (TT) SF for the science target, and (iii) finally summing both SFs. Several options for computing the SFs
are discussed. Such an approach to PSFR is general enough that is fully applicable to any type of tomographic and nontromographic
AO system, employing either laser or exclusively natural guide stars.

description: The structure of tree-level open and closed superstring amplitudes is analyzed. For the open superstring amplitude we find a striking and elegant form, which allows to disentangle its alpha'-expansion into several contributions accounting for different classes of multiple zeta values. This form is bolstered by the decomposition of motivic multiple zeta values, i.e. the latter encapsulate the alpha'-expansion of the superstring amplitude. Moreover, a morphism induced by the coproduct maps the alpha'-expansion onto a non-commutative Hopf algebra. This map represents a generalization of the symbol of a transcendental function. In terms of elements of this Hopf algebra the alpha'-expansion assumes a very simple and symmetric form, which carries all the relevant information. Equipped with these results we can also cast the closed superstring amplitude into a very elegant form.

description: Finding, acquiring, processing, analyzing, and reporting data on electronically stored data is the main goal of the forensic science discipline known as "digital forensics." Nearly all illegal acts include the use of electronic evidence, making digital forensics support essential for law enforcement investigations. Furthermore, digital forensics is very important to cases aiding in many cases and can lead to saving lives/ victims and locking up criminals. A wide range of devices, including laptops, cellphones, remote storage, unmanned aerial systems, shipborne equipment, and more, can be used to gather electronic evidence. [2] Digital forensics' major objective is to take data from electronic evidence, turn it into usable information, and then report the results to the police. All procedures make use of reliable forensic methods to guarantee that the information is acceptable in court.

description: We present forecasts on the capability of future wide-area high-sensitivity X-ray surveys of galaxy clusters to yield constraints on the parameters defining the Dark Energy (DE) equation of state (EoS). Our analysis is carried out for future X-ray surveys which have enough sensitivity to provide accurate measurements of X-ray mass proxies and Fe-line based redshifts for about 2x10^4 clusters. We base our analysis on the Fisher Matrix formalism, by combining information on the cluster number counts and power spectrum, also including, for the first time in the analysis of the large scale cluster distribution, the effect of linear redshift-space distortions (RSDs). This study is performed with the main purpose of dissecting the cosmological information provided by geometrical and growth tests, which are both included in the analysis of number counts and clustering of galaxy clusters. We compare cosmological constraints obtained by assuming different levels of prior knowledge of the parameters which define the observable-mass X-ray relation. This comparison further demonstrates the fundamental importance of having a well calibrated observable-mass relation and, most importantly, its redshift evolution. Such a calibration can be achieved only by having at least $\sim 10^3$ net photon counts for each cluster included in the survey. We show that RSDs in the power spectrum analysis carry important cosmological information also when traced with galaxy clusters and the DE FoM increases by a factor of 8. Besides confirming the potential that large cluster surveys have in constraining the nature of DE, our analysis emphasizes that a full exploitation of the cosmological information carried by such surveys requires not only a large statistic but also a robust measurement of the mass proxies and redshifts for a significant fraction of the cluster sample, derived from the same X-ray survey data.

Regulation of developmental changes in hematopoietic stem cell self-renewal
Creators: name: Copley, Michael Rebin
Publisher: name: University of British Columbia
Year: 2013

description: Mouse hematopoietic stem cells (HSCs) undergo a post-natal transition in several properties, including a marked reduction in their self-renewal activity. To investigate the molecular basis of this difference, we devised a single strategy to isolate fetal and adult HSCs at similarly high frequencies. This strategy, involving fluorescence-activated cell sorting of cells with a CD45⁺EPCR⁺CD48-CD150⁺ (ESLAM) phenotype, allows isolation of HSCs at a frequency of ~1 in 2 from all developmental time points tested (mouse embryonic day (E) 14.5 to adult). Comparison of differentially expressed genes in primitive populations of fetal and adult hematopoietic cells showed that heightened expression of Hmga2 was a feature of fetal as compared to adult HSCs. We also identified let-7 microRNAs (miRNAs) and a negative regulator of their biogenesis, Lin28b, to be expressed in an opposite and similar pattern to Hmga2, respectively. Since Hmga2 is a well-established target of let-7 miRNAs, we hypothesized that the Lin28b-let-7-Hmga2 axis plays a central role in the determination of fetal versus adult HSC self-renewal identity. We also found that Lin28 overexpression in adult HSCs restores a higher, fetal-like, self-renewal potential in them, and this effect is phenocopied by direct overexpression of Hmga2. Conversely, HSCs from fetal Hmga2-/- mice display a prematurely acquired adult-like self-renewal activity. Importantly, we show that Lin28-mediated activation of Hmga2 expression, which is responsible for the activation of a fetal-like self-renewal potential in adult HSCs, is not the mechanism by which Lin28 reprograms adult HSCs to undergo fetal-like B-cell differentiation. Together, these findings suggest a model of development in which Lin28b acts as a master regulator and Hmga2 serves as a more specific downstream modulator of HSC self-renewal. These findings may help inform strategies to improve the therapeutic use of HSCs. Furthermore, since Lin28b and Hmga2 are oncogenes, we speculate that the fetal/neonatal specific pattern of expression of these genes may contribute to the pathogenesis of pediatric leukemias.

description: EAGLE is a near-infrared wide field multi object spectrograph. It includes its own Multi-Object
Adaptive Optics system (MOAO) and its subsystems are cooled to deliver the performance in the K-band.
Due to the integrated nature of the instrument, the performance matrix has to deal with a large number of
Adaptive Optics (AO) parameters as well as the added complexity of active optical elements. To ensure
successful integration of the next generation instruments for ELT like EAGLE, it is of the utmost importance
to have method to control and manage the instrument’s critical performance characteristics. We discuss the
performance matrix we developed to automatically partition and allocate the important characteristics to the
various subsystems as well as the process to verify that the concept will deliver the required performance. We
also define a method to convert the ensquared energy and signal-to-noise ratio into the “as designed” overall
residue wavefront error.

description: A new approach to the old-standing problem of the anomaly of the scaling exponents of nonlinear models of turbulence has been proposed and tested through numerical simulations. This is achieved by constructing, for any given nonlinear model, a linear model of passive advection of an auxiliary field whose anomalous scaling exponents are the same as the scaling exponents of the nonlinear problem. In this paper, we investigate this conjecture for the 2D Navier-Stokes equations driven by an additive noise. In order to check this conjecture, we analyze the coupled system Navier-Stokes/linear advection system in the unknowns $(u,w)$. We introduce a parameter $λ$ which gives a system $(u^λ,w^λ)$; this system is studied for any $λ$ proving its well posedness and the uniqueness of its invariant measure $μ^λ$. The key point is that for any $λ\neq 0$ the fields $u^λ$ and $w^λ$ have the same scaling exponents, by assuming universality of the scaling exponents to the force. In order to prove the same for the original fields $u$ and $w$, we investigate the limit as $λ\to 0$, proving that $μ^λ$ weakly converges to $μ^0$, where $μ^0$ is the only invariant measure for the joint system for $(u,w)$ when $λ=0$.

description: We compare in this paper the analytical approach and the Monte-Carlo (MC) end-to-end approach
in the context of astronomical adaptive optics modeling. The two tools used for this purpose are the analytical
code PAOLA and the MC Software Package CAOS. This is done to inter-validate the two codes, but also to help
finding trade-offs between the MC approach, which can be very time-consuming but is expected to give more
certainty on the obtained results, and the analytic approach, which is straightforward but based on a number of
simplifying assumptions. We first test the fundamental fitting and anisoplanatic errors (the latter being equivalent
in our test to the servo-lag error), and find a very satisfactory agreement. We make then a first attempt of a
comparison including all error terms by simulating a complete 8-m telescope AO system, varying the wavefront
sensing noise. Differences are found and thought to come essentially from an unmatched definition in the two
codes of the deformable mirror modes.
title:  One protein many functions: the non-canonical interactions of SHMT1. The structural and functional characterization of SHMT1 interactions with RNA and in the de novo thymidylate synthesis complex

description: Winner of the Competition “Prize for PhD Thesis 2023” arranged by Sapienza University Press.
Several enzymes once characterized for specific metabolic roles are now recognized to have more than one function. Some metabolic enzymes, called moonlighting proteins, engage in non-canonical interactions with other proteins or nucleic acids. Interestingly, not all newly identified RNA-binding proteins regulate RNA function; sometimes, RNA itself dictates protein function through a mechanism known as riboregulation. For instance, the catalytic activity of human serine hydroxymethyltransferase (SHMT1) is modulated by RNA. Moreover, SHMT1 plays a key role in assembling the de novo thymidylate synthesis complex (dTMP-SC) in the nucleus alongside thymidylate synthase (TYMS) and dihydrofolate reductase (DHFR). This thesis aims to explore SHMT1’s non-canonical functions, focusing on the molecular mechanisms behind riboregulation. I will present the first 3D structure of a metabolic enzyme in complex with RNA, solved using cryo-electron microscopy, and characterize the dTMP-SC, highlighting its transient formation in vitro and in the cytosol. This manuscript explores how RNA regulates metabolic enzymes and transient interactions that influence function.

description: Pedagogical relationships are an important part of the educational process. Field research and student and teacher experiences indicate these relationships' valuable impact. Positive pedagogical relationships support the experience and development of all students, regardless of their needs. Positive pedagogical relationships can also support academic, emotional, and social growth. Therefore, it is vital to understand how teachers develop and maintain these relationships in their practice. This research study utilized self-study methodology to reflect on my practice related to pedagogical relationships, literature on student-teacher, and the potential of self-study research methods for practice improvement. The process included journalling for four months, focusing on ongoing assessment of practice via classroom experience, literature review, and conversations with my critical friend. The role of the critical friend is to challenge, question, and present alternate perspectives. Themes emerged related to the key concepts of love and care, nature and personality, and guidance and instruction. Love and caring require an authentic commitment and dedication to a student and the teacher on their behalf. A selfless and open teacher's personality supports the development of pedagogical relationships. Lastly, teachers must guide and instruct students to demonstrate care for the impacts on the student now and future to have lasting effects. The knowledge created by this study contributes to identifying and highlighting strategies and skills with intentions, developing a language, and reaffirming my belief about the possible profound and lasting impacts of positive pedagogical relationships on students, both in my practice and potentially transferable to others interested in this topic. In addition, the study contributes to the field of knowledge. Lastly, it suggests avenues for further research and opportunities to share the knowledge acquired with professionals in the field of education.

description: Тема регуляции предстартовых психологических состояний спортсменов на протяжении длительного времени остается актуальной. Научная литература позволяет утверждать, что регуляция предстартовых психологических состояний спортсменов оказывает большое влияние на результат соревнований в любом виде спорта. Однако
информации о подборе диагностического инструментария для фиксации состояния спортсмена, позволяющей подобрать методы регуляции предстартовых психологических состояний и его готовности к преодолению трудностей, возникающих при подготовке и проведении спортивных состязаний, недостаточно. Целью исследования был поиск подходящих методов диагностики предстартовых психологических состояний, которые
помогли бы тренерам по гребле в дальнейшем диагностировать предстартовые психологические состояния спортсменов. В статье описан процесс исследования и сделаны выводы по использованию выбранных методик.

description: We present a high accuracy Micro-Electro-Mechanical-System (MEMS) deformable mirror (DM)
control algorithm currently implemented in the real-time control interface of the Subaru Coronagraphic Extreme
Adaptive Optics project (SCExAO). MEMS DMs are an attractive DM technology for Extreme-AO (ExAO)
because they offer unprecedented actuator density and actuator counts. ExAO applications require a DM model
capable of reproducing a phase map with a precision of few nm rms. The algorithm relies (i) on a physical model
of the actuators and the membrane and (ii) on the optimization of DM coefficients and geometrical coefficients,
and could be adopted as an open-loop control solution for future MOAO or ExAO ELTs instruments. During the
initial tests performed at the UVic AO Lab, the performance of the model reached an open-loop error equal to
7.3% of the rms of the desired phase (1.6% of the peak-to-valley (PV) of the desired phase) with Kolmogorov
type wavefronts.
Estimating beta-mixing coefficients via histograms

description: The literature on statistical learning for time series often assumes asymptotic independence or "mixing" of the data-generating process. These mixing assumptions are never tested, nor are there methods for estimating mixing coefficients from data. Additionally, for many common classes of processes (Markov processes, ARMA processes, etc.) general functional forms for various mixing rates are known, but not specific coefficients. We present the first estimator for beta-mixing coefficients based on a single stationary sample path and show that it is risk consistent. Since mixing rates depend on infinite-dimensional dependence, we use a Markov approximation based on only a finite memory length $d$. We present convergence rates for the Markov approximation and show that as $d\rightarrow\infty$, the Markov approximation converges to the true mixing coefficient. Our estimator is constructed using $d$-dimensional histogram density estimates. Allowing asymptotics in the bandwidth as well as the dimension, we prove $L^1$ concentration for the histogram as an intermediate step. Simulations wherein the mixing rates are calculable and a real-data example demonstrate our methodology.

Gaussian belief propagation for real-time decentralised inference
Creators: name: Ortiz, Joseph
Publisher: name: Imperial College London
Year: 2022

description: For embodied agents to interact intelligently with their surroundings, they require perception systems that construct persistent 3D representations of their environments. These representations must be rich; capturing 3D geometry, semantics, physical properties, affordances and much more. Constructing the environment representation from sensory observations is done via Bayesian probabilistic inference and in practical systems, inference must take place within the power, compactness and simplicity constraints of real products. Efficient inference within these constraints however remains computationally challenging and current systems often require heavy computational resources while delivering a fraction of the desired capabilities. Decentralised algorithms based on local message passing with in-place processing and storage offer a promising solution to current inference bottlenecks. They are well suited to take advantage of recent rapid developments in distributed asynchronous processing hardware to achieve efficient, scalable and low-power performance. In this thesis, we argue for Gaussian belief propagation (GBP) as a strong algorithmic framework for distributed, generic and incremental probabilistic estimation. GBP operates by passing messages between the nodes on a factor graph and can converge with arbitrary asynchronous message schedules. We envisage the factor graph being the fundamental master environment representation, and GBP the flexible inference tool to compute local in-place probabilistic estimates. In large real-time systems, GBP will act as the `glue' between specialised modules, with attention based processing bringing about local convergence in the graph in a just-in-time manner. This thesis contains several technical and theoretical contributions in the application of GBP to practical real-time inference problems in vision and robotics. Additionally, we implement GBP on novel graph processor hardware and demonstrate breakthrough speeds for bundle adjustment problems. Lastly, we present a prototype system for incrementally creating hierarchical abstract scene graphs by combining neural networks and probabilistic inference via GBP.
