description: Activating mutations in KRAS occur in 32% of lung adenocarcinomas (LUAD). Despite leading to aggressive disease and resistance to therapy in preclinical studies, the KRAS mutation does not predict patient outcome or response to treatment, presumably due to additional events modulating RAS pathways. To obtain a broader measure of RAS pathway activation, we developed RAS84, a transcriptional signature optimised to capture RAS oncogenic activity in LUAD. We report evidence of RAS pathway oncogenic activation in 84% of LUAD, including 65% KRAS wild-type tumours, falling into four groups characterised by coincident alteration of STK11/LKB1, TP53 or CDKN2A, suggesting that the classifications developed when considering only KRAS mutant tumours have significance in a broader cohort of patients. Critically, high RAS activity patient groups show adverse clinical outcome and reduced response to chemotherapy. Patient stratification using oncogenic RAS transcriptional activity instead of genetic alterations could ultimately assist in clinical decision-making.

description: Quantum mechanical particles in a confining potential interfere with each other while undergoing thermodynamic processes far from thermal equilibrium. By evaluating the corresponding transition probabilities between many-particle eigenstates we obtain the quantum work distribution function, for identical Bosons and Fermions, which we compare with the case of distinguishable particles. We find that the quantum work distributions for Bosons and Fermions significantly differ at low temperatures, while, as expected, at high temperatures the work distributions converge to the classical expression. These findings are illustrated with two analytically solvable examples, namely the time-dependent infinite square well and the parametric harmonic oscillator.

description: Cooperative perception of connected vehicles comes to the rescue when the field of view restricts stand-alone intelligence. While raw-level cooperative perception preserves most information to guarantee accuracy, it is demanding in communication bandwidth and computation power. Therefore, it is important to schedule the most beneficial vehicle to share its sensor in terms of supplementary view and stable network connection. In this paper, we present a model of raw-level cooperative perception and formulate the energy minimization problem of sensor sharing scheduling as a variant of the Multi-Armed Bandit (MAB) problem. Specifically, volatility of the neighboring vehicles, heterogeneity of V2X channels, and the time-varying traffic context are taken into consideration. Then we propose an online learning-based algorithm with logarithmic performance loss, achieving a decent trade-off between exploration and exploitation. Simulation results under different scenarios indicate that the proposed algorithm quickly learns to schedule the optimal cooperative vehicle and saves more energy as compared to baseline algorithms.

description: Most research on preconditioners for time-dependent PDEs has focused on implicit multi-step or diagonally-implicit multi-stage temporal discretizations. In this paper, we consider monolithic multigrid preconditioners for fully-implicit multi-stage Runge-Kutta (RK) time integration methods. These temporal discretizations have very attractive accuracy and stability properties, but they couple the spatial degrees of freedom across multiple time levels, requiring the solution of very large linear systems. We extend the classical Vanka relaxation scheme to implicit RK discretizations of saddle point problems. We present numerical results for the incompressible Stokes, Navier-Stokes, and resistive magnetohydrodynamics equations, in two and three dimensions, confirming that these relaxation schemes lead to robust and scalable monolithic multigrid methods for a challenging range of incompressible fluid-flow models.

description: Entanglement-assisted concatenated quantum codes (EACQCs), constructed by concatenating two quantum codes, are proposed. These EACQCs show several advantages over the standard concatenated quantum codes (CQCs). Several families of EACQCs that, unlike standard CQCs, can beat the nondegenerate Hamming bound for entanglement-assisted quantum error correction codes (EAQECCs) are derived. Further, a number of EACQCs with better parameters than the best known standard quantum error correction codes (QECCs) and EAQECCs are also derived. In particular, several catalytic EACQCs with better parameters than the best known QECCs of the same length and net transmission are constructed. Furthermore, each catalytic EACQC consumes only one or two ebits. It is also shown that EACQCs make entanglement-assisted quantum communication possible even if the ebits are noisy. Finally, it is shown that EACQCs can outperform CQCs in entanglement fidelity over depolarizing channels if the ebits are less noisy than the qubits. Moreover, the threshold error probability of EACQCs is larger than that of CQCs when the error probability of ebits is sufficiently lower than that of qubits. Therefore EACQCs are not only competitive in quantum communication but also applicable in fault-tolerant quantum computation.

description: Vacuum polarization, a key prediction of quantum theory, can cause a variety of intriguing phenomena that can be triggered by high-intensity laser pulses. The Heisenberg-Euler theory of the quantum vacuum supplements Maxwell's theory of electromagnetism with nonlinear photon-photon interactions mediated by vacuum fluctuations. This work presents a numerical solver for the leading weak-field Heisenberg-Euler corrections. The present code implementation reaches an accuracy of order thirteen in the numerical scheme and takes into account up to six-photon interactions. Since theoretical approaches are limited to approximations and the experimental requirements for signal detection are high, the need for support from the numerical side is apparent.

title: Untersuchung zur psychophysiologischen und emotionalen Wirkung von improvisierter Live-Musik
Creators: name: Maier, Daniela Maria
Year: 2009

description: Es sind zwar einige Annahmen über die Wirkung von Live-Musik und Improvisation bekannt, doch gibt es einen Mangel an Untersuchungen auf diesem Gebiet. In der vorliegenden Studie sollte überprüft werden, ob sich psychophysiologische und emotionale Unterschiede zwischen Live- und aufgenommener Musik sowie zwischen improvisierter und reproduzierter Musik zeigen. Insgesamt nahmen 27 Frauen und 26 Männer an der Untersuchung teil. Die Testpersonen wurden in 4 Gruppen unterteilt, welche in unterschiedlicher Reihenfolge dieselben Musikstücke hörten. Dabei wurden vor Beginn der Untersuchung sowie nach jeder Musikdarbietung die Stimmung erhoben und physiologische Parameter mittels Elektrokardiogramm gemessen. Die Ergebnisse sprechen für ein angenehmeres Musikerlebnis von Live-Musik in Bezug auf die erlebten Stimmungen, während sich zwischen Improvisation und Reproduktion keine vergleichbaren Unterschiede zeigen. In den physiologischen Reaktionen zeigen sich kaum signifikante Unterschiede. Zusätzlich wurde eine Untersuchung durchgeführt, die überprüfen sollte, ob sich Lautstärkeeffekte zeigen. Es nahmen 30 Frauen und 12 Männer teil. Die Durchführung erfolgte analog zur Hauptuntersuchung. In den Stimmungen zeigt sich eine Tendenz eines angenehmeren Musikerlebens der leisen gegenüber der lauten Musik und der reproduziertern gegenüber der improvisierten Musik. Die Musikdarbietungen führen auch hier nur zu wenigen unterschiedlichen physiologischen Reaktionen.

description: We prove that the Lipschitz-free space over a Banach space $X$ of density $κ$, denoted by $\mathcal{F}(X)$, is linearly isomorphic to its $\ell_1$-sum $\left(\bigoplus_κ\mathcal{F}(X)\right)_{\ell_1}$. This provides an extension of a previous result from Kaufmann in the context of non-separable Banach spaces. Further, we obtain a complete classification of the spaces of real-valued Lipschitz functions that vanish at $0$ over a $\mathcal{L}_p$-space. More precisely, we establish that, for every $1\leq p\leq \infty$, if $X$ is a $\mathcal{L}_p$-space of density $κ$, then $\mathrm{Lip}_0(X)$ is either isomorphic to $\mathrm{Lip}_0(\ell_p(κ))$ if $p<\infty$, or $\mathrm{Lip}_0(c_0(κ))$ if $p=\infty$.

description: The equatorial current sheet in pulsar magnetospheres is often regarded as an ideal site for particle acceleration via relativistic reconnection. Using 2D spherical particle-in-cell simulations, we investigate particle acceleration in the axisymmetric pulsar magnetosphere as a function of the injected plasma multiplicity and magnetization. We observe a clear transition from a highly charge-separated magnetosphere for low plasma injection with little current and spin-down power, to a nearly force-free solution for high plasma multiplicity characterized by a prominent equatorial current sheet and high spin-down power. We find significant magnetic dissipation in the current sheet, up to 30% within 5 light-cylinder radii in the high-multiplicity regime. The simulations unambiguously demonstrate that the dissipated Poynting flux is efficiently channeled to the particles in the sheet, close to the Y-point within about 1-2 light cylinder radii from the star. The mean particle energy in the sheet is given by the upstream plasma magnetization at the light cylinder. The study of particle orbits shows that all energetic particles originate from the boundary layer between the open and the closed field lines. Energetic positrons always stream outward, while high-energy electrons precipitate back towards the star through the sheet and along the separatrices, which may result in auroral-like emission. Our results suggest that the current sheet and the separatrices may be the main source of high-energy radiation in young pulsars.

description: Let $H$ be a Hilbert space and $(Ω,\mathcal{F},μ)$ a probability space. A Hilbert point in $L^p(Ω; H)$ is a nontrivial function $φ$ such that $\|φ\|_p \leq \|φ+f\|_p$ whenever $\langle f, φ\rangle = 0$. We demonstrate that $φ$ is a Hilbert point in $L^p(Ω; H)$ for some $p\neq2$ if and only if $\|φ(ω)\|_H$ assumes only the two values $0$ and $C>0$. We also obtain a geometric description of when a sum of independent Rademacher variables is a Hilbert point.

The loop quantum gravitational effects will be incorporated in the collapsing system using gravity's rainbow. This will be done by using rainbow functions, which are constructed from loop quantum gravitational modifications to the energy momentum dispersion. It will be observed that this modification will prevent the formation of naked singularity. Thus, such a modification can ensures that the weak cosmic censorship hypothesis will hold for any collapsing system.

description: We develop a general theoretical framework to dynamically engineer quantum correlations in the frequency-comb emission from an array of superconducting qubits in a waveguide, rigorously accounting for the temporal modulation of the qubit resonance frequencies. We demonstrate, that when the resonance frequencies of the two qubits are periodically modulated with a $π$ phase shift, it is possible to realize simultaneous bunching and antibunching in cross-correlations of the scattered photons from different sidebands. Our approach, based on the dynamical conversion between the quantum excitations with different parity symmetry, is quite universal. It can be used to control two-particle correlations in generic dynamically modulated dissipative quantum systems.

description: We use the field theory description of the fractional quantum Hall states to derive the universal response of these topological fluids to shear deformations and curvature of their background geometry, i.e. the Hall viscosity, the Wen-Zee term, and the gravitational Chern-Simons term. To account for the coupling to the background geometry, we show that the concept of flux attachment needs to be modified and use it to derive the geometric responses from Chern-Simons theories. We show that the resulting composite particles minimally couple to the spin connection of the geometry. We derive a consistent theory of geometric responses from the Chern-Simons effective field theories and from parton constructions, and apply it to both abelian and non-abelian states.

description: Ziel dieser Arbeit ist es, den Einfluss touristischer Angebote auf eine traditionelle Kultur in Namibia zu untersuchen. Im Mittelpunkt steht die Frage nach der Wirkung zweier unterschiedlicher Vermarktungskonzepte (Living Museum und Conservancy) auf die traditionellen Heilrituale der Ju/’hoansi aus der Region Nyae Nyae unter besonderer Berücksichtigung der Frage, inwiefern es sich bei den Vorführungen um Rituale oder um Theateraufführungen handelt. Unter Heranziehung von Turners Theorie des „sozialen Dramas“ und Schechners Theorie der Performance werden Kriterien zur Unterscheidung Ritual-Theateraufführung erarbeitet und mit empirischen Beobachtungen zweier Feldforschungen im Jahr 2014 verglichen. Für die Bewertung der Authentizität der Darbietungen im touristischen Kontext wird auf MacCannells Beschreibung des „Authentischen“ und auf Goffmans Frontstage-Backstage-Dichotomie zurückgegriffen. Es wird gezeigt, dass sich sowohl Form wie Organisation der Performances in den beiden oben genannten Konzepten unterscheiden. Weiters gibt es auch Unterschiede hinsichtlich der Frage, was den TouristInnen als „traditionell“ und „authentisch“ gezeigt werden soll. Während die Heilrituale im Living Museum eher Theateraufführungen gleichen, finden sich in jenen der Conservancy deutlich die Eigenschaften eines Rituals, wobei die Einschätzung auch mit der Person des Heilers in Zusammenhang steht. Mehrere Fragen können in der vorliegenden Arbeit nicht behandelt werden: Werden die Heilrituale als solche auch in Zukunft außerhalb des touristischen Kontexts gepflegt? In welche Richtung entwickelt sich die in beiden Vermarktungskonzepten geforderte Pflege der Tradition? Und: Trägt der Tourismus zur Zerstörung traditioneller Kultur oder zu ihrer Wiederbelebung und Verstärkung bei?

description: We present a general formalism for incorporating the string corrections in generalised geometry, which necessitates the extension of the generalised tangent bundle. Not only are such extensions obstructed, string symmetries and the existence of a well-defined effective action require a precise choice of the (generalised) connection. The action takes a universal form given by a generalised Lichnerowitz--Bismut theorem. As examples of this construction we discuss the corrections linear in $α'$ in heterotic strings and the absence of such corrections for type II theories.

STRATEGIES FOR AN OPTOGENETIC MODULATION OF THE PACEMAKER CURRENT IF
Creators: name: ZUCCOLINI, PAOLO
Publisher: name: Universit� degli Studi di Milano
Year: 2019

description: HCN4 channels control pacemaking of the heart. They are activated by negative voltage and modulated by cAMP. Recently it had been discovered that cyclic di-nucleotides bind to a second site in the channel C-terminus. This counteracts the effect of cAMP on shifting channel activation positive. A bacterial cyclase, which synthesizes c-di-GMP in response to red light, allows engineering of an optogenetic system for remote HCN4 modulation and hence for controlling the heart pace. Two cyclases were used in this work: one constitutively active (Slr1143) and one red ligh-regulated (BphS). Because the latter has some dark activity, it is co-expressed with a phosphodiesterase (YhjH). Recordings of HCN4 activity in HEK293T cells show that Slr1143 affects the voltage dependence of the channel, shifting the activation curve negative with respect to the control. Experiments with BphS show no difference in HCN4 activity between light and dark treated cells. The combined BphS-YhjH expression seemed to be unable to increase the c-di-GMP concentration in a light dependent manner. To examine the effect of light on c-di-GMP production we quantified the cyclic di-nucleotide with an established ELISA assays in HEK293T cells and with an immune-fluorescence method. The latter consisted of monitoring expression of interferon-? in BphS-YhjH expressing T cells. Cyclic di-nucleotides can activate the STING pathway, which augments synthesis of interferon-?. Both methods underlined that Slr1143 and BphS-YhjH system increased the level of c-di-GMP in cells. This activity, however, was not light regulated. The immuno-fluorescence data indicate a slightly higher expression of the constitutive compared to the light-regulated cyclase. This may explain why we observed an effect of the former but not of the latter on HCN4 gating. Eliminating YhjH did not affect the level of c-di-GMP, suggesting that the phosphodiesterase is insufficient for eliminating c-di-GMP dark production. The data confirm previous results in that c-di-GMP is able to modulate HCN4 activity. BphS is not yet suitable as an optogenetic tool because of its high dark activity. This problem may be overcome by increasing the expression/activity of the phosphodiesterase in the next iteration of engineering an optogenetic tool.
Symmetry-protected adiabatic quantum transistors

description: Adiabatic quantum transistors allow quantum logic gates to be performed by applying a large field to a quantum many-body system prepared in its ground state, without the need for local control. The basic operation of such a device can be viewed as driving a spin chain from a symmetry protected phase to a trivial phase, and this perspective offers an avenue to generalise the adiabatic quantum transistor and to design several improvements. The performance of quantum logic gates is shown to depend only on universal symmetry properties of a symmetry-protected phase rather than fine tuned parent Hamiltonians, and it is possible to implement a universal set of logic gates in this way by combining several different types of symmetry protected matter. Such symmetry-protected adiabatic quantum transistors are argued to be robust to a range of relevant noise processes.

THE SOCIAL FROM THE ECONOMIC: THE EMERGENCE OF SOLIDARITY WITHIN NETWORKS OF ECONOMIC EXCHANGE
Creators: name: BIANCHI, FEDERICO
Publisher: name: Universit� degli Studi di Milano
Year: 2017

description: In this dissertation, we attempted to contribute to the discussion about the link between the economic and the social. More specifically, we addressed the debate on the consequences of economically-oriented interaction on social relations. Sociological studies have mostly focused on understanding the opposite direction, i.e., the effect of social relations on economic outcomes. Conversely, our work was motivated by the idea that the consequences of the economic on the social is crucial for social sciences and society in general. First, we reviewed the literature on solidarity and exchange relations in sociology and the behavioural sciences. The chapter aimed to elaborate a theoretical framework and working hypotheses for the following chapters. We proposed a definition of solidarity at the behavioural level and various empirical contributions have been examined. Next, we conducted an empirical study on the link between professional collaboration and social support relations. In this work, certain hypotheses were tested on a group of independent professionals sharing a ?coworking? space. Here, we found that solidarity can emerge as a by-product of economic exchange among strangers if they are allowed to select each other for collaboration and develop trust relations. The following chapter presents an extensive literature review of the use of Agent-Based Models (ABM) for sociological research. Given the key role of this methodology in this dissertation, the chapter aims to provide a comprehensive account of the contributions to sociology given by applications of ABM computer simulations. Moreover, a classification of these contributions is proposed according to the various methodological approaches to ABM in social research. The aim of the chapter is to review ABM as a possible means to overcome some limitations of the study presented before. Then, the final study applies computer simulation to analyze cohesion and integration of a social support network from economic exchange. In this chapter, an ABM of the mechanisms observed in the previous empirical study is presented. The model is used to simulate the effect of competition and resource distribution on social support networks. The aim of this work is to explore the effects of different environmental conditions and overcome the context-specific properties of empirical data. We argue that competition over most attractive collaborators can undermine the emergence of a cohesive social support network. Yet, this detrimental effect can be avoided if we assume that poor-resource actors are more eager to ask others for support, therefore generating a cohesive and more integrated social support network. Finally, we drew some conclusions in the last chapter.

description: The energy-dependent scattering of fermions from a localized orbital at an energy-dependent rate $Γ(ε)\propto |ε|^r$ gives rise to quantum critical points (QCPs) in the pseudogap single-impurity Anderson model separating a local moment phase with an unscreened spin moment from a strong-coupling phase which slightly deviates from the screened phase of standard Kondo problem. Using the time-dependent numerical renormalization group (TD-NRG) approach we show that local dynamic properties always equilibrate towards a steady-state value even for quenches across the QCP but with systematic deviations from the thermal equilibrium depending on the distance to the critical coupling. Local non-equilibrium properties are presented for interaction quenches and hybridization quenches. We augment our numerical data by an analytical calculation that becomes exact at short times and find excellent agreement between the numerics and the analytical theory. For interaction quenches within the screened phase we find a universal function for the time-dependent local double occupancy. We trace back the discrepancy between our results and the data obtained by a time-dependent Gutzwiller variational approach to restrictions of the wave-function ansatz in the Gutzwiller theory: while the NRG ground states properly account for the formation of an extended spin moment which decouples from the system in the unscreened phase, the Gutzwiller ansatz only allows the formation of the spin moment on the local impurity orbital.
Non-zero $θ_{13}$, CP-violation and Neutrinoless Double Beta Decay for Neutrino Mixing in the $A_4\times Z_2\times Z_3$ Flavor Symmetry Model

description: We study the modification of the Altarelli-Feruglio $A_4$ flavor symmetry model by adding three singlet flavons $ξ'$, $ξ''$ and $ρ$ and the model is augmented with extra $Z_2\times Z_2^ \prime$ symmetry to prevent the unwanted terms in our study. The addition of these three flavons lead to two higher order corrections in the form of two perturbation parameters $ε$ and $ε^\prime$. These corrections yield the deviation from exact tri-bimaximal (TBM) neutrino mixing pattern by producing a non-zero $θ_{13}$ and other neutrino oscillation parameters which are consistent with the latest experimental data. In both the corrections, the neutrino masses are generated via Weinberg operator. The analysis of the perturbation parameters $ε$ and $ε^\prime$, shows that normal hierarchy (NH) and inverted hierarchy (IH) for $ε$ does not change much. However, as the values of $ε^\prime$ increases, $θ_{23}$ occupies the lower octant for NH case. We further investigate the neutrinoless double beta decay parmeter $m_{ββ}$ using the parameter space of the model for both normal and inverted hierarchies of neutrino masses.

description: Superconductivity forms out of the condensation of Cooper pairs of electrons. The mechanism by which Cooper pairs are created in non-conventional superconductors is often elusive because experimental signatures that connect a specific pairing mechanism to the properties of superconducting state are rare. The recently discovered superconducting oxide-insulator/KTaO$_3$ interface may offer clues about its origins. Here we observe distinct dependences of the superconducting transition temperature Tc on carrier density n$_{2D}$ for electron gases formed at KTaO$_3$ (111), (001) and (110) interfaces. For the KTaO$_3$ (111) interface, a remarkable linear dependence of Tc on n$_{2D}$ is observed over a range of nearly one order of magnitude. Further, our study of the dependence of superconductivity on gate electric fields reveals the role of the interface in mediating superconductivity, which also allows for a reversible electric switching of superconductivity at T = 2 K. We found that the extreme sensitivity of superconductivity to crystallographic orientation can be explained by Cooper pairing via inter-orbital interactions induced by the inversion-breaking transverse optical (TO1) phonons and quantum confinement. This mechanism is also consistent with the dependence of Tc on n$_{2D}$ at the KTaO$_3$ (111) interface. Our study may shed light on the pairing mechanism in other superconducting quantum-paraelectrics.

description: The superconducting properties of Sn1-xInxTe (x = 0.38 to 0.45) have been studied using magnetization and muon-spin rotation or relaxation (muSR) measurements. These measurements show that the superconducting critical temperature Tc of Sn1-xInxTe increases with increasing x, reaching a maximum at around 4.8 K for x = 0.45. Zero-field muSR results indicate that time-reversal symmetry is preserved in this material. Transverse-field muon-spin rotation has been used to study the temperature dependence of the magnetic penetration depth lambda(T) in the mixed state. For all the compositions studied, lambda(T) can be well described using a single-gap s-wave BCS model. The magnetic penetration depth at zero temperature lambda(0) ranges from 500 to 580 nm. Both the superconducting gap Delta(0) at 0 K and the gap ratio Delta(0)/kBTc indicate that Sn1-xInxTe (x = 0.38 to 0.45) should be considered as a superconductor with intermediate to strong coupling.

description: We construct a new inflation model in which the standard model Higgs boson couples minimally to gravity and acts as the inflaton. Our construction of Higgs inflation incorporates the standard model with Einstein gravity which exhibits asymptotic safety in the ultraviolet region. The slow roll condition is satisfied at large field value due to the asymptotically safe behavior of Higgs self-coupling at high energies. We find that this minimal construction is highly predictive, and is consistent with both cosmological observations and collider experiments.

description: Das Konzept des Seelengefährts, das bereits von Platon und zuvor von Parmenides konzipiert wurde, ist für die philosophische Selbstverständigung von der Antike bis in die frühe Au lärung und darüber hinaus die moderne Esoterik von zentraler Bedeutung. Sein veranschaulichendes Potenzial reicht von der Erkundung der Möglichkeiten der Kommunikation zwischen eigentlich klar voneinander geschiedenen ontologischen Räumen – dem des Unsto ich-Göttlichen einerseits und dem des Sto ich-Irdischen bzw. menschlich Seelischen andererseits – bis hin zu natur philosophischen Entwürfen zur Erklärung des Phänomens der Elektrizität. Immer wieder wurde es von so unterschiedlichen Denkern wie z. B. Plutarch, Bernardus Silvestris, Kepler, Suarez oder Christian Wolf herangezogen, um das Problem der Einwirkung des Intelligiblen und Göttlichen auf die menschliche Seele oder die irdische Natur zu erklären. Es motivierte Dichter wie Traherne oder Donne zu literarischen Inszenierungen sympathetisch-aitherischer Leiblichkeit und deren eschatologischen Implikationen. Diesem zentralen und spannungsvollen Themenspektrum in seiner historischen wie thematischen Kontinuität nähern sich die Autor*innen dieses Bandes aus interdisziplinär verschränkter Perspektive, die zudem eine innovative, künstlerische Auseinandersetzung mit den verschiedenen Aspekten des Licht(-leib)es umfasst.

description: Spin-orbit coupling (SOC) effects occurring in noncentrosymmetric materials are known to be responsible for nontrivial spin configurations and a number of emergent physical phenomena such as electrical control of spin degrees of freedom and spin-to-charge conversion. The materials preserving a uniform spin configuration in the momentum-space, known as persistent spin texture (PST), provide long carrier spin lifetimes through persistent spin helix (PSH) mechanism. However, most of the PST studied till now are attributed to the linear in \textbf{\textit{k}} splitting and cease to exist locally around certain high-symmetry-point of first Brillouin Zone (FBZ). The persistent spin textures with purely cubic spin splittings have drawn attention owing to unique benefits in spin transport. Here, by using the relativistic first-principles calculations supplemented with \textbf{\textit{k.p}} analysis, we report the emergence of purely cubic splitting (PCS) belonging to $D_{3h}$ point group, which is enforced by in-plane mirror and three-fold rotation operations. In addition, the in-plane mirror symmetry operation sustains the PST in larger region (i.e. full planes) of FBZ alongside giant spin splitting. Our results also demonstrate how application of uniaxial strain could be envisaged to tune the magnitude of the PCS, preserving the PST. The observed PSTs provide a route to non-dephasing spin transport with larger spin-Hall conductivity, thus offering a promising platform for future spintronics devices.

description: We introduce network $L$-cloning, a technique for creating ensembles of random networks from any given real-world or artificial network. Each member of the ensemble is an $L$-cloned network constructed from $L$ copies of the original network. The degree distribution of an $L$-cloned network and, more importantly, the degree-degree correlation between and beyond nearest neighbors are identical to those of the original network. The density of triangles in an \LC network, and hence its clustering coefficient, is reduced by a factor of $L$ compared to those of the original network. Furthermore, the density of loops of any fixed length approaches zero for sufficiently large values of $L$. Other variants of $L$-cloning allow us to keep intact the short loops of certain lengths. As an application, we employ these network cloning methods to investigate the effect of short loops on dynamical processes running on networks and to inspect the accuracy of corresponding tree-based theories. We demonstrate that dynamics on $L$-cloned networks (with sufficiently large $L$) are accurately described by the so-called adjacency tree-based theories, examples of which include the message passing technique, some pair approximation methods, and the belief propagation algorithm used respectively to study bond percolation, SI epidemics, and the Ising model.
