IRGC (2022) Ensuring the environmental sustainability of emerging technologies - 1. Workshop report
Creators: name: Florin, Marie-Valentine
Publisher: name: Lausanne, EPFL
Year: 2022

description: This report assumes that something can be done to guide technology developers and others towards producing technology that does not cause indirect and delayed damage to the environment. It explores the extent to which environmental sustainability concerns are taken into account and what can be done in five distinct technology domains: chemicals and advanced materials, synthetic biology, digital technologies, carbon dioxide removal (CDR) and sequestration, and space technologies. It also describes the current attitude and instruments available or being considered to reach the goal of environmental sustainability. Thus, it suggests ways to address ex-ante environmental concerns that might manifest only after design choices for technology are already made.

description: In this paper we investigate a generation mechanism of the non-Abelian gauge fields in the SU(N) gauge theory. It is shown that the SU(N) gauge fields ensuring the local invariance of the theory are generated at the quantum level only due to nonsmoothness of the scalar phases of the fundamental spinor fields. The expression for the gauge fields are obtained in terms of the nonsmooth scalar phases.

description: The role of response operators is well established in quantum mechanics. We investigate their use for universal quantum machine learning models of response properties in molecules. After introducing a theoretical basis, we present and discuss numerical evidence based on measuring the potential energy's response with respect to atomic displacement and to electric fields. Prediction errors for corresponding properties, atomic forces and dipole moments, improve in a systematic fashion with training set size and reach high accuracy for small training sets. Prediction of normal modes and IR-spectra of some small molecules demonstrates the usefulness of this approach for chemistry.

description: Onset of permanent deformation in crystalline materials under a sharp indenter tip is accompanied by nucleation and propagation of defects. By measuring the spatio-temporal strain field nearthe indenter tip during indentation tests, we demonstrate that the dynamic strain history at the moment of a displacement burst carries characteristics of formation and interaction of local excitations, or solitons. We show that dynamic propagation of multiple solitons is followed by a short time interval where the propagating fronts can accelerate suddenly. As a result of such abrupt local accelerations, duration of the fast-slip phase of a failure event is shortened. Our results show that formation and annihilation of solitons mediate the microscopic fast weakening phase, during which extreme acceleration and collision of solitons lead to non-Newtonian behavior and Lorentz contraction, i.e., shortening of solitons characteristic length. The results open new horizons for understanding dynamic material response during failure and, more generally, complexity of earthquake sources.

description: The data of four recent experiments --- conducted in Delft, Vienna, Boulder, and Munich with the aim of refuting nonquantum hidden-variables alternatives to the quantum-mechanical description --- are evaluated from a Bayesian perspective of what constitutes evidence in statistical data. We find that each of the experiments provides strong, or very strong, evidence in favor of quantum mechanics and against the nonquantum alternatives. This Bayesian analysis supplements the previous non-Bayesian ones, which refuted the alternatives on the basis of small p-values, but could not support quantum mechanics.

description: Concepts of type and typology are not specific to architecture. Rather they represent an interdisciplinary approach to ordering knowledge and gaining insight. In the field of architecture, the study of types and typology offers a didactic perspective that allows us to see the complex network of inter-connections between theory and practice as an inseparable material and social construct. This publication is the result of a research project focused on dormitories as an architectural type, conducted at Laboratory EAST and produced in the frame of the teaching activities of the laboratory. Through a structured analysis, it unveils inherent knowledge of architectural solutions associated to the activity of sleeping collectively. The publication includes a theoretical framework with texts by Prof. Anja Fröhlich, Estelle Lépine, Arne Winkelmann, Tiago P. Borges and Vanessa Pointet.
The Needs and Experiences of Caregivers to Persons with Dementia (PWD) who have Lost their Driving Privileges

Older adults

description: The ability to drive a motor vehicle for most older adults is associated with a sense of independence, well-being, quality of life and identity. For many older adults, driving cessation is an inevitability. This is especially the case for older adults with a diagnosis of dementia. Driving cessation has been shown to negatively impact individuals’ mobility and, consequently, quality of life. Informal caregivers (i.e., family caregivers) can mitigate the negative consequences associated with driving cessation in persons with dementia (PWD) by meeting their mobility needs and by offering emotional support. The purpose of this study was to examine the experience and needs of informal caregivers of PWD who had recently lost their driving privileges. Ten informal caregivers of PWD were recruited from a tertiary memory disorders clinic. Semi-structured interviews were conducted and transcribed. Transcripts of interviews were analyzed using an inductive thematic analysis approach. Thematic analysis revealed that caregivers expressed the need to receive transportation training and more information on transportation alternatives. Caregivers also expressed the need for psychological services, such as individual therapy, grief therapy or group therapy with other caregivers of PWD. The experiences and needs of caregivers indicate that driving cessation of the care recipient is a difficult experience for caregivers and that a therapeutic intervention based on the reported needs may be beneficial.

description: WO3 thin films were grown by atomic layer deposition and spectroscopic ellipsometry data gathered in the photon energy range of 0.72-8.5 eV and from multiple samples was utilized to determine the frequency dependent complex-valued isotropic dielectric function for WO3. We employ a critical-point model dielectric function analysis and determine a parameterized set of oscillators and compare the observed critical-point contributions with the vertical transition energy distribution found within the band structure of WO3 calculated by density functional theory. We investigate surface roughness with atomic force microscopy and compare to ellipsometric determined effective roughness layer thickness.

description: This collection gathers all the articles that were submitted and presented at the 20th European Conference on Composite Materials (ECCM20) which took place in Lausanne, Switzerland, June 26-30,2022. ECCM20 is the 20th edition of a conference series having its roots back in time, organized each two years by members of the European Society of Composite Materials (ESCM). The ECCM20 event was organized by the Composite Construction laboratory (CCLab) and the Laboratory for Processing of Advanced Composites (LPAC) of the Ecole Polytechnique Fédérale de Lausanne (EPFL). The Conference Theme this year was “Composites meet Sustainability”. As a result, even if all topics related to composite processing, properties and applications have been covered, sustainability aspects were highlighted with specific lectures, roundtables and sessions on a range of topics, from bio-based composites to energy efficiency in materials production and use phases, as well as end-of-life scenarios and recycling. More than 1000 participants shared their recent research results and participated to fruitful discussions during the five conference days, while they contributed more than 850 papers which form the six volumes of the conference proceedings. Each volume gathers contributions on specific topics : Vol 1 – Materials Vol 2 – Manufacturing Vol 3 – Characterization Vol 4 – Modeling and Prediction Vol 5 – Applications and Structures Vol 6 – Life Cycle Assessment We enjoyed the event; we had the chance to meet each other in person again, shake hands, hold friendly talks, and maintain our long-lasting collaborations. We appreciated the high level of the research presented at the conference and the quality of the submissions that are now collected in these six volumes. We hope that everyone interested in the status of the European Composites’ research in 2022 will be fascinated by this publication.

description: Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) regulates collagen-mediated platelet activation through its cytoplasmic immunoreceptor tyrosine-based inhibition motifs (ITIMs). However, the function of CEACAM1’s extracellular cleavage fragments is currently unknown. In the present study, we used mass spectrometry (MS) to identify 9 cleavage fragments shed by matrix metallopeptidase 12 (MMP-12), and then we synthesized peptides with sequences corresponding to the fragments. QLSNGNRTLT (QLSN), a peptide from the A1-domain of CEACAM1, significantly attenuated collagen-induced platelet aggregation. QLSN also attenuated platelet static adhesion to collagen. Additionally, QLSN reduced human platelet secretion and integrin αIIbβ3 activation in response to glycoprotein VI (GPVI)–selective agonist, convulxin. Correspondingly, QLSN treatment significantly decreased convulxin-mediated phosphorylation of Src, protein kinase B (Akt), spleen tyrosine kinase (Syk) and phospholipase Cγ2 (PLCγ2) in human platelets. These data indicate that the CEACAM1-derived peptide QLSN inhibits GPVI-mediated human platelet activation. QLSN could potentially be developed as a novel antiplatelet agent. QLSN inhibit collagen-induced human platelet activation through glycoprotein VI.
The Critical Role of the Boundary Layer Thickness for the Initiation of Aeolian Sediment Transport

description: Here, we propose a conceptual framework of Aeolian sediment transport initiation that includes the role of turbulence. Upon increasing the wind shear stress $τ$ above a threshold value $τ^\prime_t$, particles resting at the bed surface begin to rock in their pockets because the largest turbulent fluctuations of the instantaneous wind velocity above its mean value $\overline{u}$ induce fluid torques that exceed resisting torques. Upon a slight further increase of $τ$, rocking turns into a rolling regime (i.e., rolling threshold $τ_t\simeqτ^\prime_t$) provided that the ratio between the integral time scale $T_i\proptoδ/\overline{u}$ (where $δ$ is the boundary layer thickness) and the time $T_e\propto\sqrt{d/[(1-1/s)g]}$ required for entrainment (where $d$ is the particle diameter and $s$ the particle-air-density ratio) is sufficiently large. Rolling then evolves into mean-wind-sustained saltation transport provided that the mean wind is able to compensate energy losses from particle-bed rebounds. However, when $T_i/T_e$ is too small, the threshold ratio scales as $τ_t/τ^\prime_t\propto{T}_e/T_i\propto{s}d^2/δ^2$, consistent with experiments. Because $δ/d$ controls $T_i/T_e$ and the relative amplitude of turbulent wind velocity fluctuations, we qualitatively predict that Aeolian sediment transport in natural atmospheres can be initiated under weaker (potentially much weaker) winds than in wind tunnels, consistent with indirect observational evidence on Earth and Mars.
Low-carbon transition risk
Creators: name: Collins, Aengus
Publisher: name: Lausanne, EPFL
Year: 2020

description: As evidence of climate change mounts, the urgency increases of transitioning to a low-carbon economy and society. There is a need for greater attention on the countervailing “transition risks” to which the low-carbon transition is likely to give rise. This article defines transition risk and outlines seven categories of such risks. It concludes by calling for more work to assess, evaluate and mitigate these risks, and to develop the tools and methods needed to deal with the systemic interconnections between them.

description: We present precision calculations of the processes e+e- -> 4-fermions in which the double resonant W+W- intermediate state occurs. Referring to this latter intermediate state as the 'signal process', we show that, by using the YFS Monte Carlo event generators YFSWW3-1.14 and KORALW1.42 in an appropriate combination, we achieve a physical precision on the signal process, as isolated with LEP2 MC Workshop cuts, below 0.5 per cent. We stress the full gauge invariance of our calculations and we compare our results with those of other authors where appropriate. In particular, sample Monte Carlo data are explicitly illustrated and compared with the results of the program RacoonWW of Dittmaier {\it et al.}. In this way, we show that the total (physical plus technical) precision tag for the WW signal process cross section is 0.4 per cent for 200 GeV, for example. Results are also given for 500 GeV with an eye toward the LC.

Induced Polarization from Birefringent Pulse Splitting in Magnetoionic Media

Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Birefringence in ionized, magnetized media is usually measured as Faraday rotation of linearly polarized radiation. However, pulses propagating through regions with very large Faraday rotation measures (RMs) can split into circularly polarized components with measurable differences in arrival times $\propto ν^{-3}\, \rm RM$, where $ν$ is the radio frequency. Differential refraction from gradients in DM (dispersion measure) and RM can contribute a splitting time $\propto \vert \mathbf{\nabla_{\perp}} \rm DM \vert \vert \mathbf{\nabla_{\perp}}\rm RM \vert\,ν^{-5}$. Regardless of whether the emitted pulse is unpolarized or linearly polarized, net circular polarization will be measured when splitting is a significant fraction of the pulse width. However, the initial polarization may be inferable from the noise statistics of the bursts. Extreme multipath scattering that broadens pulses can mask splitting effects. We discuss particular cases such as the Galactic center magnetar, J1749$-$2900, and the repeating fast radio burst source, FRB 121102. Both lines of sight have $\rm RM \sim 10^5~\rm rad~m^{-2}$ that yields millisecond splittings at frequencies well below $\sim 1 \text{ GHz}$. We also consider the splitting of nanosecond shot pulses in giant pulses from the Crab pulsar and the minimal effects of birefringence on precision pulsar timing. Finally, we explore the utility of two-dimensional coherent dedispersion with DM and RM as parameters.

description: The properties of a nonrelativistic charged particle in two dimensions in the presence of an arbitrary number of nonquantized magnetic fluxes are investigated in free space as well as in a uniform magnetic field. The fluxes are represented mathematically as branch points in one of the complex coordinates. It is found that in order to construct solutions, the fluxes have to be treated in general as dynamical objects dual to the charges. A medium made up of fluxes acts like an anti-magnetic field and tends to expel the charges.

description: A new isoflavonoid, excelsanone (2), was isolated from the ethyl acetate extract of Erythrina excelsa stem bark, together with three known compounds namely 6,8-diprenylgenistein (3), β-sitosterol (1) and sitosteryl-β-D-glucopyranoside (4). Their structures were elucidated using spectroscopic methods (HR-ESI-MS, NMR and IR) and by comparison with some literature data. The antioxidant activity of crude extracts and two isolated compounds was evaluated using free radical scavenging (DPPH) and Ferric Reducing Ability Power (FRAP) methods with catechin as standard. The results of the radical scavenging activity showed that excelsanone (2) has a moderate potential with an IC50 of 1.31 mg/ml. The cytotoxicity of compounds 2 and 3 as well as the ethyl acetate extract was evaluated using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in two prostate cancer cell lines (DU145 and PC3). Excelsanone (2) induced a greater cytotoxicity in all tested cell lines, with a significant inhibition of DU145 cells growth in a concentration-dependent manner.

description: Calculations of the Casimir energy for spherical geometries which are based on integrations of the stress tensor are critically examined. It is shown that despite their apparent agreement with numerical results obtained from mode summation methods, they contain a number of serious errors. Specifically, these include (1) an improper application of the stress tensor to spherical boundaries, (2) the neglect of pole terms in contour integrations, and (3) the imposition of inappropriate boundary conditions upon the relevant propagators. A calculation which is based on the stress tensor and which avoids such problems is shown to be possible. It is, however, equivalent to the mode summation method and does not therefore constitute an independent calculation of the Casimir energy.

description: We identify a vertical extension of the red clump stars in the color magnitude diagram (CMD) of a section of the Large Magellanic Cloud (LMC). After subtracting the principal red clump component, we find a peak in the residual stellar distribution that is ~ 0.9 mag brighter than the peak of the principal red clump distribution. We consider and reject the following possible explanations for this population: inhomogeneous reddening, Galactic disk stars, random blends of red clump stars, correlated blends of red clump stars (binaries), evolution of the red clump stars, and red clump stars from a younger LMC stellar population. Combinations of these effects cannot be ruled out as the origin of this stellar population. A natural interpretation of this new population is that it consists of red clump stars that are closer to us than those in the LMC. We find corroborating evidence for this interpretation in Holtzman et al.'s (1997) Hubble Space Telescope CMD of the LMC field stars. The derived distance and projected angular surface density of these stars relative to the LMC stars (

description: In this paper we give five gauge-invariant systems of governing equations for first and second order scalar perturbations of flat Friedmann-Lemaître universes that are minimal in the sense that they contain no redundant equations or variables. We normalize the variables so that they are dimensionless, which leads to systems of equations that are simple and ready-to-use. We compare the properties and utility of the different systems. For example, they serve as a starting point for finding explicit solutions for two benchmark problems in cosmological perturbation theory at second order: adiabatic perturbations in the super-horizon regime (the long wavelength limit) and perturbations of $Λ$CDM universes. However, our framework has much wider applicability and serves as a reference for future work in the field.

description: Tephrosia apollinea is a legume species, native to southwest Asia and northeast Africa, rich in bioactive flavonoids (hydrophilic compounds). T. apollinea seeds were not considered previously as a potential source of lipophilic compounds such as: essential fatty acids, tocopherols, sterols, and squalene, hence, the present study were performed. The oil yield in T. apollinea seeds amounted to 11.8% dw. The T. apollinea seed oil was predominated by the polyunsaturated fatty acids - linoleic (26.8%) and α-linolenic (22.7%). High levels were recorded also for oleic (27.6%) and palmitic (14.9%) acids. Four tocopherols and one tocotrienol, with the domination of γ-tocopherol (98%) were identified in T. apollinea seed oil. The β-sitosterol (59%), Δ5-stigmasterol (21%) and campesterol (9%) were detected as main sterols in T. apollinea seed oil. The total content of tocochromanols, sterols, carotenoids and squalene in the T. apollinea seed oil was 256.7, 338.1, 12.5 and 1103.8 mg/100 g oil, respectively. T. apollinea seeds oil, due to the high concentration of lipophilic bioactive compounds can find a potential application in the food, cosmetic and pharmaceutical industry.
Non-intrusive Subdomain POD-TPWL Algorithm for Reservoir History Matching

description: This paper presents a non-intrusive subdomain POD-TPWL (SD POD-TPWL) algorithm for reservoir data assimilation through integrating domain decomposition (DD), radial basis function (RBF) interpolation and the trajectory piecewise linearization (TPWL). It is an efficient approach for model reduction and linearization of general non-linear time-dependent dynamical systems without intruding the legacy source code. In the subdomain POD-TPWL algorithm, firstly, a sequence of snapshots over the entire computational domain are saved and then partitioned into subdomains. From the local sequence of snapshots over each subdomain, a number of local basis vectors is formed using POD, and then the RBF interpolation is used to estimate the derivative matrices for each subdomain. Finally, those derivative matrices are substituted into a POD-TPWL algorithm to form a reduced-order linear model in each subdomain. This reduced-order linear model makes the implementation of the adjoint easy and resulting in an efficient adjoint-based parameter estimation procedure. The performance of the new adjoint-based parameter estimation algorithm has been assessed through several synthetic cases. Comparisons with the classic finite-difference based history matching show that our proposed subdomain POD-TPWL approach is obtaining comparable results. The number of full-order model simulations required is roughly 2-3 times the number of uncertain parameters. Using different background parameter realizations, our approach efficiently generates an ensemble of calibrated models without additional full-order model simulations.

IRGC (2023) Ensuring the environmental sustainability of emerging technologies - 3. Guidance to distinct actors
Creators: name: Florin, Marie-Valentine
Publisher: name: Lausanne, International Risk Governance Center
Year: 2023

description: To support economic development, governments and industries in major countries are committing to massive new technological investments before, or perhaps without, undertaking a comprehensive assessment of their environmental impacts. Existing policy frameworks concerning some emerging technology applications do not provide sufficient clarity for how these technologies will be regulated, especially if the risk of environmental harm is not proven and impacts are indirect or manifest in the longer term. For example, this is the case of the transition to a digital economy that requires building massive data centres; innovation in advanced materials such as semiconductors or smart materials 1 expected to offer major improvements in a wide variety of domains; or the transition to all-electric vehicles. Do we know the full extent of consequences on the environment?
Hipparcos and the Age of the Galactic Disc

Publisher: name: arXiv
Year: 1997
Subjects: subject: Astrophysics (astro-ph)

description: We have used the Hipparcos satellite colour magnitude diagram to determine the age of the Galactic disc. We first measure the metallicities of Hipparcos giants using DDO photometry (Høg & Flynn 1997). With accurate metallicities and distances we compute the minimum age of the Galactic disc as $11\pm1$ Gyr using the colour of the reddest clump stars as a function of metallicity. In conjunction with the new ages derived for Globular Clusters using the same method (Jimenez et al 1996) we show that any delay between the formation of the halo and the disc was only 2-3 Gyr. Since disc galaxies may have been detected to redshifts as high as $z=3.15$ (Lu, Sargent and Barlow 1997) an age for our own Galactic disc of 11 Gyr favours open or non-zero $Λ$ cosmological models. We show that a Reimers mass-loss law is sufficient to explain the morphology of the red clump.

description: This publication documents the ongoing interdisciplinary research project “A Prototype Pavilion in Textile Reinforced Concrete (TRC)” by the EPFL laboratories ALICE and IBETON and research partners from the FAUFBA, Salvador de Bahia, Brazil.  The TRC Prototype Pavilion, built by students and researchers in civil engineering and architecture at EPFL Fribourg, is a proof of concept of a long-established research on TRC’s structural, spatial, tectonic and social potential. The construction of the pavilion is modular and conceived to be dismantled, its aim is in the first place to test and expose innovative and sustainable construction knowledge. The TRC Prototype Pavilion builds on research conducted during the ENAC teaching unit ‘Argamassa Armada’ (EPFL, since 2016) which is named after the Brazilian term for ferrocement. The teaching unit ‘Argamassa Armada’ analyzes and reiterates in textile reinforced concrete (TRC) selected structural elements developed by João da Gama Filgueiras Lima, Lelé (1932-2014) in ferrocement. This crossing of Brazilian industrial knowledge and contemporary research on non-corrosive fiber reinforcement creates the conceptual basis for the design, mold fabrication and casting of new slender elements in textile reinforced concrete, the conceptual basis for the TRC Prototype Pavilion (since 2019).  It is intended to be a first step towards adaptable tectonic systems, a modular construction that will be further developed the next years and lead to a new lightweight building technique, forecasting a new and different conception and image of concrete construction at large the TRC Pavilion acts as a messenger for concrete as a social and sustainable "light" material.
Diagrammatic notations for interactive theorem proving
Creators: name: Chiplunkar, Shardul
name: Pit-Claudel, Clément
Publisher: name: EPFL
Year: 2023

description: Diagrams are ubiquitous in the development and presentation of proofs, yet surprisingly uncommon in computerized mathematics. Instead, authors and developers rely almost exclusively on line-oriented notations (textual abbreviations and symbols). How might we enrich interactive theorem provers with on-the-fly visual aids that are just as usable? We answer this question by identifying a key challenge: designing declarative languages for composable diagram templates, that provide good-looking implementations of common patterns, and allow for rapid prototyping of diagrams that remain stable across transformations and proof steps.
On analytical perturbative solution of ABJM quantum spectral curve

description: Recently we showed how non-homogeneous second-order difference equations appearing within ABJM quantum spectral curve description could be solved using Mellin space technique. In particular we provided explicit results for anomalous dimensions of twist 1 operators in sl(2) sector at arbitrary spin values up to four loop order. It was shown that the obtained results may be expressed in terms of harmonic sums decorated by fourth root of unity factors, so that maximum transcendentality principle holds. In this note we show that the same result could be also obtained by direct solution of the mentioned equations in spectral parameter u-space. The solution involves new highly nontrivial identities between hypergeometric functions, which may have various other applications. We expect this method to be more easily generalizable to higher loop orders as well as to other theories, such as N=4 SYM.

description: The $γ^* γ\to πππ$ reaction is analysed in QCD at large photon virtuality Q and small hadronic mass W. Its amplitude factorizes in a $3 π$ generalized distribution amplitude and a hard subprocess $γ^* γ\to q \bar q$ or $γ^* γ\to g g$. The interference of this process with a Brehmsstrahlung process in e e or $e γ$ collisions gives rise to interesting single spin asymmetries, particularly when W is near the $ω$ mass.

description: Neogenkwanine I (1), a new daphnane-type diterpene with 4,7-ether group, along with four known ones (2–5), were isolated from Daphne genkwa. The structure including absolute configurations of 1 was established on the basis of NMR, 13C-NMR and ECD calculations and CD exciton chirality analysis. 13C-NMR and ECD calculations of daphnane-type diterpenes were reported here for the first time. All of the diterpenes were screened for their cytotoxic activities against MCF-7 and Hep3B cell lines. The cytotoxicity structure- activity relationship of compounds was illustrated with the absence of ortho-ester group of daphnane-type diterpenes.

description: A total of nine stone artifacts were submitted for protein residue analysis from sites Hi0v80, HiOv16, HiOv83, HiOv126, and HiOv92, located in northern Alberta, Canada. Archaeological activities are related to the 2008 Fort Hills mitigation (FMA Project 115708.MI08). These sites are within the Central Mixedwood Natural Subregion of the Boreal Forest Region. Previous analysis of artifacts from this region have yielded a high rate of positive protein residue results, likely due to the predominantly cool climate and low biological activity in the soil. The goal of the present analysis is to gain a better understanding of animal subsistence at these sites.
