Adapting the FAMILY framework to the teaching and learning of multimodal literacy at the primary level
Creators: name: Lim, Joylynn Chew Yen

Publisher: name: Journal of Applied Linguistics
Year: 2022

description: The affordances brought about by digital media and technology have changed the way we now read and view texts. Literacy has moved beyond its traditional sense of alphabetic literacy to reading and viewing texts with more than one semiotic mode. In response to this changing way of how texts are presented and viewed, multiliteracies is one of the pedagogical emphases in the 2020 EL Syllabus. This study attempts to find out if the intentional teaching of the aspects in the FAMILY framework (Lim Tan, 2017) will allow pupils to make informed and coherent interpretations of a poster. An adapted model of the FAMILY framework will subsequently be proposed to better suit the learning needs of primary school students.

description: This study investigates the bilingual profiles of Indian students in the Greek context. Indian students comprise a minority group that is highly underexamined in the Greek literature, in contrast to other minority groups in Greece (e.g., Albanians, see Chatzidaki Maligkoudi, 2013; Mattheoudakis et al., 2020). In particular, this article examines the bilingual profiles and the language behavior of sixteen (16) Indian students in the Greek educational context, namely in two schools in Attica. Content analysis of their interviews was applied, with the aim of exploring their bilingual profiles, their patterns of language choice and use as well as their attitude towards their home languages. Our findings reveal that the main language of communication adopted in the school environment (outside and inside the classroom) is Greek. On the other hand, Hindi or Punjabi are mostly used in the home environment, mainly due to the fact that mothers have a low proficiency in Greek. The results of our study also highlight how our participants perceive the role of host classes in their integration into the educational process.

description: We present the Phase A Science Case for the Multi-conjugate Adaptive-optics Visible Imager-Spectrograph (MAVIS), planned for the Adaptive Optics Facility (AOF) of the Very Large Telescope (VLT). MAVIS is a general-purpose instrument for exploiting the highest possible angular resolution of any single optical telescope available in the next decade, either on Earth or in space, and with sensitivity comparable to (or better than) larger aperture facilities. MAVIS uses two deformable mirrors in addition to the deformable secondary mirror of the AOF, providing a mean V-band Strehl ratio of >10% (goal >15%) across a relatively large (30 arc second) science field. This equates to a resolution of <20mas at 550nm - comparable to the K-band diffraction limit of the next generation of extremely large telescopes, making MAVIS a genuine optical counterpart to future IR-optimised facilities like JWST and the ELT. Moreover, MAVIS will have unprecedented sky coverage for a high-order AO system, accessing at least 50% of the sky at the Galactic Pole, making MAVIS a truly general purpose facility instrument. As such, MAVIS will have both a Nyquist-sampled imager (30x30 arcsec field), and a powerful integral field spectrograph with multiple spatial and spectral modes spanning 370-1000nm. This science case presents a distilled set of thematically linked science cases drawn from the MAVIS White Papers (www.mavis-ao.org/whitepapers), selected to illustrate the driving requirements of the instrument resulting from the recent MAVIS Phase A study.

Analytical framework for thermoacoustic devices and experimental validation
Creators: name: Lu, Xiaofeng
Publisher: name: Imperial College London
Year: 2019

description: Thermoacoustic devices represent a significant future opportunity in the fields of energy generation and refrigeration. A key component of this type of device is the regenerator, where the conversion between acoustic energy and thermal energy takes place. This conversion occurs due to an externally imposed temperature gradient on the wall of the regenerator channels. Hence, this study concerns the physics of sound waves in the proximity of such walls. It establishes a new analytical framework which clarifies the disturbance energy conservation in thermoacoustic devices. In this framework, a thermoacoustic production term is proposed to quantify the generation or consumption of disturbance energy originating from the temperature gradient. An extended disturbance energy flux term is identified to account for wave growth or decay through the regenerator. The disturbance energy balance relation states that the disturbance energy flux equals the thermoacoustic production less the viscous and thermal dissipation resulting from gradients of fluctuating velocity and temperature. The analytical framework is implemented into an axisymmetric cylindrical domain; the two-dimensional nature of this work helps to uncover that the wave always decays in the region close to the wall. A dimensional analysis is conducted to identify the controlling parameters, namely the Womersley, Helmholtz and Prandtl numbers. A parametric study of the Womersley and Helmholtz numbers is conducted to showcase the new analytical methodology; the results make it possible to optimize the geometry, wave properties and working conditions of a thermoacoustic device according to the preference of its efficiency, loss and output. This study then validates the analysis in an actual thermoacoustic engine environment. A straight waveguide with a loudspeaker at one end and wave absorbing material at the other simulates a travelling-wave condition of various frequencies. A novel regenerator consisting of 671 thin stainless-steel tubes were inserted into two copper heat exchangers to form an integral block. The design enables reproduction of the geometry and a known, constant, precisely controlled wall temperature gradient as in the model. The selection of material also encourages radial heat conduction while minimising the axial one. The experimental results show excellent agreement with the numeral model and validates the analytical framework proposed. The maximum measured wave growth was 1.76 when the temperature difference between hot and cold end of the regenerator was 303K.

description: We address the problem of implementing high fidelity one-qubit operations subject to time dependent noise in the qubit energy splitting. We show with explicit numerical results that high fidelity bit flips and one-qubit NOT gates may be generated by imposing bounded control fields. For noise correlation times shorter than the time for a pi-pulse, the time optimal pi-pulse yields the highest fidelity. For very long correlation times, fidelity loss is approximately due to systematic error, which is efficiently tackled by compensation for off-resonance with a pulse sequence (CORPSE). For intermediate ranges of the noise correlation time we find that short CORPSE, which is less accurate than CORPSE in correcting systematic errors, yields higher fidelities. Numerical optimization of the pulse sequences using gradient ascent pulse engineering results in noticeable improvement of the fidelities for the bit flip and marginal improvement for the NOT gate.

description: This paper reports on results of a quantitative study investigating Language Learning Strategies (LLS) that teachers of Greek L2/Turkish L1 in dual-immersion primary schools promote as well as the possible effect of gender, teaching experience and education level on their LLS promotion. The particular schools are separate schools for bilingual children (L1 Turkish/L2 Greek) in Thrace, Greece. Their societal and educational aims are language maintenance, pluralism and enrichment whereas the linguistic aim is bilingualism and biliteracy. However, the students’ Greek language proficiency and their general academic achievement are low. The study was conducted as part of in-service teacher training aiming to provide teachers with teaching methodology on LLS. It examines 102 self-evaluations of the strategies L1 and L2 teachers promote in class. Our findings show that the teachers reported high frequency of strategy promotion. There were significant differences on individual strategies between L1 and L2 teachers. Lastly, gender, teaching experience, and education level appeared to be predictors of LLS promotion.

An event-based robot control architecture
Creators: name: Yu, Jie
Publisher: name: University of British Columbia
Year: 2009

description: The robot control system is a subsystem of a robot designed to regulate its behaviours to meet certain requirements. For a mobile robot performing in a real-world environment, its control system must have the capability to be both deliberative and reactive. In addition to this fundamental requirement, robustness, timely response and: coordination among multiple goals are also desirable for a mobile robot control system. This thesis addresses these requirements in building a mobile robot control system and proposes an Event-based Robot Control Architecture (ERA). . .v The unpredictable nature of the real-world environment leads to the development of our Event-based Robot Control Architecture. All communications inside the control: architecture are done in the form of events. Our focus for the mobile robot control architecture is on using an exception mechanism for error recovery. Exceptions are one kind of events. We present a general design and a system prototype for an Event-based Robot Control Architecture. The implementation was used to conduct experiments ,and identify the benefits and limitations of the proposed paradigm. It was found that a mobile robot using this Event-based Robot Control Architecture meets the previously established requirements.
Odd-frequency pair density wave in the Kitaev-Kondo lattice model

description: We investigate the properties of the Kitaev-Kondo lattice model defined on a bilayer honeycomb lattice by means of the SO(3) Majorana representation for spin-$1/2$ moments. We first consider the pairing of neighboring sites for the parent Kitaev spin liquid (KSL) Hamiltonian to render the Majorana and the spin-$1/2$ Hilbert spaces perfectly equivalent to each other. As a consequence, we demonstrate that this decoupling of the Kitaev interaction in terms of the SO(3) Majorana fermions reproduces exactly the spectrum of the KSL model alone. Then, by considering the effect of a local Kondo coupling $J_K$ in the model and decoupling it in terms of an order parameter that physically must have a finite staggering phase, we obtain that the system undergoes a quantum phase transition from a fractionalized Fermi liquid to a nematic triplet superconducting (SC) phase as $J_K$ is increased. Depending on the model parameters, this SC phase can exhibit either Dirac points, Bogoliubov-Fermi lines, or Bogoliubov-Fermi surfaces as nodal bulk manifolds. The surface states in this latter case are also characterized by topologically protected antichiral edge modes. The SC phase breaks time-reversal symmetry and exhibits a coexistence of a dominant odd-frequency pairing with a small even-frequency component for electronic excitations localized on sites of the same sublattice of the system. Finally, we show that this SC phase is in fact a pair-density-wave state, with Cooper pairs possessing a finite center-of-mass momentum in zero magnetic field.

Mott transition and electronic excitation of the Gutzwiller wavefunction

description: The Mott transition is usually considered as resulting from the divergence of the effective mass of the quasiparticle in the Fermi-liquid theory; the dispersion relation around the Fermi level is considered to become flat towards the Mott transition. Here, to clarify the characterization of the Mott transition under the assumption of a Fermi-liquid-like ground state, the electron-addition excitation from the Gutzwiller wavefunction in the $t$-$J$ model is investigated on a chain, ladder, square lattice, and bilayer square lattice in the single-mode approximation using a Monte Carlo method. The numerical results demonstrate that an electronic mode that is continuously deformed from a non-interacting band at zero electron density loses its spectral weight and gradually disappears towards the Mott transition. It exhibits essentially the magnetic dispersion relation shifted by the Fermi momentum in the small-doping limit as indicated by recent studies for the Hubbard and $t$-$J$ models, even if the ground state is assumed to be a Fermi-liquid-like state exhibiting gradual disappearance of the quasiparticle weight. This implies that, rather than as the divergence of the effective mass or disappearance of the carrier density that is expected in conventional single-particle pictures, the Mott transition can be better understood as freezing of the charge degrees of freedom while the spin degrees of freedom remain active, even if the ground state is like a Fermi liquid.

New flavor physics in di- and tri-lepton events from single-top at the LHC and beyond

description: The associated production of a single-top with opposite-sign same-flavor (OSSF) di-leptons, $pp \to t \ell^+ \ell^-$ and $ pp \to t \ell^+ \ell^- + j$ ($j=$light jet), can lead to striking tri-lepton $pp \to \ell^\prime \ell^+ \ell^- + X$ and di-lepton $pp \to \ell^+ \ell^- + j_b + X$ ($j_b=b$-jet) events at the LHC, after the top decays. Although these rather generic multi-lepton signals are flavor-blind, they can be generated by new 4-Fermi flavor changing (FC) $u_i t \ell \ell$ scalar, vector and tensor interactions ($u_i \in u,c$), which we study in this paper; we match the FC $u_i t \ell \ell$ 4-Fermi terms to the SMEFT operators and also to different types of FC underlying heavy physics. The main backgrounds to these di- and tri-lepton signals arise from $t \bar t$, $Z$+jets and $VV$ ($V=W,Z$) production, but they can be essentially eliminated with a sufficiently high invariant mass selection on the OSSF di-leptons, $m_{\ell^+ \ell^-}^{\tt min}(OSSF) > 1$ TeV; the use of $b$-tagging as an additional selection in the di-lepton final state case also proves very useful. We find, for example, that the expected 95\% CL bounds on the scale of a tensor(vector) $u t μμ$ interaction, with the current $\sim 140$ fb$^{-1}$ of LHC data, are $Λ< 5(3.2) $ TeV or $Λ< 4.1(2.7)$ TeV, if analyzed via the di-muon $μ^+ μ^- + j_b$ signal or the $e μ^+ μ^-$ tri-lepton one, respectively. The expected reach at the HL-LHC with 3000 fb$^{-1}$ of data is $Λ< 7.1(4.7)$ TeV and $Λ< 2.4(1.5)$ TeV for the corresponding $u t μμ$ and $c t μμ$ operators. We also study the potential sensitivity at future 27 TeV and 100 TeV high-energy LHC successors and also discuss the possible implications of this class of FC 4-Fermi effective interactions on lepton non-universality tests at the LHC.

Imaging heterogeneous glucose metabolism during tumour proliferation and migration
Creators: name: Kondo, Hiroshi
Publisher: name: Imperial College London
Year: 2019

description: The tumour microenvironment plays an important role in tumour proliferation, invasion, and metastasis. In particular, cancer cells can exist in heterogeneous states within the complex tumour microenvironment including different nutrient accessibility, oxygen concentration, extracellular pH, and extracellular matrix (ECM) stiffness. Cancer cell characteristics vary among individual cells and metabolic reprogramming is a key feature of tumour microenvironmental adaptation. Cancer cells can switch nutrient source depending on the micro-environment with variation in the effect of aerobic glycolysis. Although heterogeneous metabolism in cancer cells is expected, experimental approaches to analyse cell metabolism at single cell resolution are limited. In order to investigate heterogeneous cancer cell metabolism, I validated a fluorescence resonance energy transfer (FRET)-based glucose biosensor in breast cancer cell lines. Notably, I observed breast cancer cell lines have heterogeneous intracellular glucose levels and I analysed the functional significance of this metabolic heterogeneity. Multiplexed imaging clarified that high glucose cells take in and consume glucose faster than low glucose cells. Metabolomic analysis further revealed that high and low glucose cells mainly employ glycolysis and oxidative phosphorylation (OXPHOS), respectively. This inter-cellular heterogeneity is established by phosphoinositide 3-kinase (PI3K) signalling pathway and actin cytoskeletal dynamics. Migrating cells dramatically increase intracellular glucose levels by activating the PI3K/AKT signalling pathway and actin cytoskeletal remodelling. PI3K inhibitors can supress glycolysis and the proliferation of breast cancer cells. However, a subset of cells have a PI3K-independent mechanism to regulate glycolysis. Histone acetylation and its reader Bromodomain regulate cell metabolism. Combinatorial inhibition of PI3K and Bromodomain can effectively supress tumour growth.

title: The politics of carbon pricing in Canada: a case study of Ontario stakeholders participation and deliberation in Canada's federal carbon pricing policy process
Creators: name: Yankey, Ignatius Kobbina
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: Public and stakeholder participation and deliberation in environmental governance have been acknowledged and endorsed by several international principles and organizations as saliently sine qua non in unlocking solutions to “wicked” problems. Like in other countries, Canadian law recognizes and endorses the benefits of these elements. Accordingly, the federal government consulted and gathered inputs from various stakeholder groups during the development of its carbon pricing policy. However, there have been stakeholder acceptability problems and legitimacy challenges with the policy in Ontario. This thesis, therefore, explores and analyzes the role of the public and stakeholders in participatory and deliberative processes that occurred during the federal carbon pricing policy development, using Ontario stakeholders’ engagement as a case. Using a qualitative research approach, participants from government/bureaucrats, political parties, academia/experts, ENGOs, and businesses/industries involved in the processes were interviewed. Key issues and questions structured around the study’s objectives revealed that although there were participatory processes, which affected some aspects of the final policy decision, the processes were deficient in several key aspects. The processes employed by the policy designers, even though, were restricted to tokenism, therapy, manipulation, and group interest politics, they reflected the input, preferences, and values of most of the stakeholders. Unfortunately, the existing and emerging major controversies and disputes were left unresolved during and after the processes, which have affected the policy’s legitimacy and acceptability in Ontario. Given the various fundamental ideologies of the political parties/organizations, and their approaches to climate change and emissions reductions in Canada’s climate history, no nationally coordinated policy decisions about climate change will be free from political tensions, criticisms, and controversies. This thesis suggests that it is prudent for the federal government to continue with the policy so far as it is meeting its intended purpose, while engaging the dissenting stakeholders since policymaking is an unending process. The thesis concludes by recommending approaches that could be used to improve participatory processes and serve as a yardstick to assess other practices in future projects. It also calls on researchers to look into how Canadian provinces can achieve unity in solving “wicked problems” like the GHG emissions.

description: We have resolved Kelu-1 into a binary system with a separation of ~290 mas using the Laser Guide Star Adaptive Optics system on the Keck II telescope. We have also re-analyzed a 1998 HST observation of Kelu-1 and find that the observed PSF is best fit by a binary object separated by 45 mas. Observations on multiple epochs confirm the two objects share a common proper motion and clearly demonstrate the first evidence of orbital motion. Kelu-1B is fainter than Kelu-1A by 0.39+/-0.01 magnitudes in the K' filter and 0.50+/-0.01 magnitudes in the H filter. We derive spectral types of L2+/-1 and L3.5+/-1 for Kelu-1A and B, respectively. The separation of flux into the two components rectifies Kelu-1's over-luminosity problem that has been known for quite some time. Given the available data we are able to constrain the inclination of the system to >81 degrees and the orbital period to >~40 years.

description: We give a broad overview of the history of microwave superconductivity and explore the technological developments that have followed from the unique electrodynamic properties of superconductors. Their low loss properties enable resonators with high quality factors that can nevertheless handle extremely high current densities. This in turn enables superconducting particle accelerators, high-performance filters and analog electronics, including metamaterials, with extreme performance. The macroscopic quantum properties have enabled new generations of ultra-high-speed digital computing and extraordinarily sensitive detectors. The microscopic quantum properties have enabled large-scale quantum computers, which at their heart are essentially microwave-fueled quantum engines. We celebrate the rich history of microwave superconductivity and look to the promising future of this exciting branch of microwave technology.

description: The problem of reconstructive surgery for facial defects, its social and economic aspects remain on the agenda in Ukraine and around the world. The study of the factors of effectiveness of reconstructive surgery of facial defects is an urgent problem of plastic surgery, and the implementation of appropriate systematic review allows to determine the status and future prospects and priorities of research in this area. Identification of the main clusters of factors of efficiency of reconstructive surgery of facial defects by conducting a systematic review of the scientific literature on this issue. The systematic review includes the following types of studies: systematic reviews, randomized clinical trials, cohort studies, case-control studies, sectional studies, case studies, case series. Publications that contain data on reconstructive plastic surgery of facial defects. The search was conducted in the following databases: PubMed, Cochrane Library, Scopus, Web of Science. Excel and R software were used for analysis. According to the inclusion criteria, publications devoted to certain aspects of determining the factors of effectiveness of reconstructive surgery for facial defects were selected. There is a significant predominance (p <0.01) of type studies, in descending order: description of individual cases, series of cases, sectional, "case-control". Factors for the effectiveness of reconstructive surgery of facial defects relate to medical and biological (congenital, acquired) aspects of each individual, environmental factors of natural, man-made nature, organizational and administrative issues, qualifications of medical professionals and technological equipment, as well as psychological status and psychological microclimate etc. The prospect of further research is to conduct an appropriate phase of meta-analysis of data selected at the current stage.

description: In honor of Igor Dzyaloshinskii on his 90th birthday, we revisit his pioneering work on the linear magnetoelectric effect in light of the modern theory of ferroelectric polarization. We show that the surface magnetic dipole moment associated with magnetoelectric materials is analogous to the bound surface charge in ferroelectrics, in that it can be conveniently described in terms of a bulk magnetoelectric multipolization that is analogous to the ferroelectric polarization. We define the intrinsic surface magnetization to be this surface magnetic dipole moment per unit area, and provide a convenient recipe for extracting it for any surface plane, from knowledge of the bulk magnetic order. We demonstrate the procedure for the prototypical magnetoelectric material, Cr$_2$O$_3$, in which Dzyaloshinskii first identified the linear magnetoelectric effect, and compare the value of the intrinsic surface magnetization to recent experimental measurements. Finally, we argue that non-magnetoelectric antiferromagnets whose multipolization lattices do not contain zero should have an intrinsic surface magnetization, in the same way that non-polar insulators whose polarization lattices do not contain zero have an intrinsic surface charge.

description: The reactions gamma gamma -> pi^+pi^-pi^+pi^- and gamma gamma -> pi^+pi^0pi^-pi^0 are studied with the L3 detector at LEP in a data sample collected at centre-of-mass energies from 161GeV to 209GeV with a total integrated luminosity of 698/pb. A spin-parity-helicity analysis of the rho^0 rho^0 and rho^+ rho^- systems for two-photon centre-of-mass energies between 1GeV and 3GeV shows the dominance of the spin-parity state 2+ with helicity 2. The contribution of 0+ and 0- spin-parity states is also observed, whereas contributions of 2- states and of a state with spin-parity 2+ and zero helicity are found to be negligible.

description: We study in detail various information theoretic quantities with the intent of distinguishing between different charged sectors in fractionalized states of large-$N$ gauge theories. For concreteness, we focus on a simple holographic $(2+1)$-dimensional strongly coupled electron fluid whose charged states organize themselves into fractionalized and coherent patterns at sufficiently low temperatures. However, we expect that our results are quite generic and applicable to a wide range of systems, including non-holographic. The probes we consider include the entanglement entropy, mutual information, entanglement of purification and the butterfly velocity. The latter turns out to be particularly useful, given the universal connection between momentum and charge diffusion in the vicinity of a black hole horizon. The RT surfaces used to compute the above quantities, though, are largely insensitive to the electric flux in the bulk. To address this deficiency, we propose a generalized entanglement functional that is motivated through the Iyer-Wald formalism, applied to a gravity theory coupled to a $U(1)$ gauge field. We argue that this functional gives rise to a coarse grained measure of entanglement in the boundary theory which is obtained by tracing over (part) of the fractionalized and cohesive charge degrees of freedom. Based on the above, we construct a candidate for an entropic $c$-function that accounts for the existence of bulk charges. We explore some of its general properties and their significance, and discuss how it can be used to efficiently account for charged degrees of freedom across different energy scales.

Subnational analysis and modelling of the Ebola epidemic in West Africa, 2013-2016: application of machine learning algorithms for case fatality imputation
Creators: name: Forna, Alpha
Publisher: name: Imperial College London
Year: 2020

description: Background The 2013-2016 West African Ebola epidemic has been the largest to date with more than 11,000 deaths in the affected countries. The data collected have provided more insight into the case fatality ratio (CFR) and how it varies with age and other characteristics. However, the accuracy and precision of the naïve CFR remain limited because 44% of survival outcomes were unreported. Methods Using a machine learning (MaLe) model, Boosted Regression Tree (BRT), I imputed survival outcomes (i.e. survival or death) when unreported, corrected for model imperfection to estimate the CFR without imputation, with imputation and adjusted with imputation. I used semivariogram analysis and kriging to investigate subnational heterogeneities in CFR estimates. I used simulations to evaluate the performance of various MaLe inference methods for the estimation of CFR under different outbreak data scenarios. Results The adjusted CFR estimates were 82.8% (95% CI 45%.6-85.6%) overall and 89.1% (95% CI 40.8%-91.6%), 65.6% (95% CI 61.3%-69.6%) and 79.2% (95% CI 45.4%-84.1%) for Sierra Leone, Guinea and Liberia, respectively. BRT modelling accounted for most of the spatiotemporal variation and interactions in CFR, but moderate spatial autocorrelation remained. Combining district-level CFR estimates and kriged district-level residuals provided the best linear unbiased map of CFR. Temporal autocorrelation was not observed in the district-level residuals from the BRT estimates. Finally, I observed that the performance of MaLe inference methods for CFR imputation varies under different outbreak data scenarios. Conclusions Adjusted CFR estimates improved the naïve CFR estimates obtained without imputation and were more representative. Used in conjunction with other resources, adjusted CFR estimates and the unbiased CFR maps will inform future public health response to Ebola outbreaks. I confirm that, across the board, data imputation with adjustment for the sensitivity and specificity of MaLe inference methods reduces the bias in CFR estimates.

description: Chemical doping of topological materials may provide a possible route for realizing topological superconductivity. However, all such cases known so far are based on chalcogenides. Here we report the discovery of superconductivity induced by Re doping in the topological semimetal Mo$_{5}$Si$_{3}$ with a tetragonal structure. Partial substitution of Re for Mo in Mo$_{5-x}$Re$_{x}$Si$_{3}$ results in an anisotropic shrinkage of the unit cell up to the solubility limit of approximately $x$ = 2. Over a wide doping range (0.5 $\leq$ $x$ $\leq$ 2), these silicides are found to be weakly coupled superconductors with a fully isotropic gap. $T_{\rm c}$ increases monotonically with $x$ from 1.67 K to 5.78 K, the latter of which is the highest among superconductors of the same structural type. This trend in $T_{\rm c}$ correlates well with the variation of the number of valence electrons, and is mainly ascribed to the enhancement of electron-phonon coupling. In addition, band structure calculations reveal that superconducting Mo$_{5-x}$Re$_{x}$Si$_{3}$ exhibits nontrivial band topology characterized by $Z_{2}$ invariants (1;000) or (1;111) depending on the Re doping level. Our results suggest that transition metal silicides are a fertile ground for the exploration of candidate topological superconductors.
