description: We investigate the in-plane spin relaxation of electrons due to the D'yakonov-Perel' and Elliot-Yafet mechanisms including the intra- and inter-valley processes in monolayer MoS$_2$. We construct the effective Hamiltonian for the conduction band using the Löwdin partition method from the anisotropic two-band Hamiltonian with the intrinsic spin-orbit coupling of the conduction band included. The spin-orbit coupling of the conduction band induces the intra- and inter-valley D'yakonov-Perel' spin relaxation. In addition, the Elliot-Yafet spin relaxation also takes place due to the interband spin mixing. We find that the D'yakonov-Perel' mechanism dominates the in-plane spin relaxation. In the framework of this mechanism, the intravalley process is shown to play a more important role at low temperature whereas the intervalley one becomes more important at high temperature. At the temperature in between, the leading process of the in-plane spin relaxation changes from the intervalley to intravalley one as the electron density increases. Moreover, we find that the intravalley process is dominated by the electron-electron Coulomb scattering even with high impurity density since the dominant term in the spin-orbit coupling is isotropic, which does not lead to the spin relaxation together with the electron-impurity scattering. This is very different from the previous studies in semiconductors and graphene.

description: The spin of an electron or a nucleus in a semiconductor [1] naturally implements the unit of quantum information -- the qubit -- while providing a technological link to the established electronics industry [2]. The solid-state environment, however, may provide deleterious interactions between the qubit and the nuclear spins of surrounding atoms [3], or charge and spin fluctuators in defects, oxides and interfaces [4]. For group IV materials such as silicon, enrichment of the spin-zero 28-Si isotope drastically reduces spin-bath decoherence [5]. Experiments on bulk spin ensembles in 28-Si crystals have indeed demonstrated extraordinary coherence times [6-8]. However, it remained unclear whether these would persist at the single-spin level, in gated nanostructures near amorphous interfaces. Here we present the coherent operation of individual 31-P electron and nuclear spin qubits in a top-gated nanostructure, fabricated on an isotopically engineered 28-Si substrate. We report new benchmarks for coherence time (> 30 seconds) and control fidelity (> 99.99%) of any single qubit in solid state, and perform a detailed noise spectroscopy [9] to demonstrate that -- contrary to widespread belief -- the coherence is not limited by the proximity to an interface. Our results represent a fundamental advance in control and understanding of spin qubits in nanostructures.

description: The AC magnetic susceptibility is a fundamental method in materials science, which allows to probe the dynamic magnetic response of magnetic materials and superconductors. The LAMPS laboratory at the Laboratori Nazionali di Frascati of the INFN hosts an AC multi-harmonic magnetometer that allows performing experiments with an AC magnetic field ranging from 0.1 to 20 Gauss and in the frequency range from 17 to 2070 Hz. A DC magnetic field from 0 to 8 T produced by a superconducting magnet can be applied, while data may be collected in the temperature range 4.2-300 K using a liquid He cryostat under different temperature cycles setups. The first seven AC magnetic multi-harmonic susceptibility components can be measured with a magnetic sensitivity of 1x10-6 emu and a temperature precision of 0.01 K. Here we will describe in detail about schematic of the magnetometer, special attention will be dedicated to the instruments control, data acquisition framework and the user-friendly LabVIEW-based software platform.

description: The calcium-silicate-hydrate is used to model properties of cement on Earth. We study cementitious nanoparticles and propose these structures as components of cosmic dust grains. Quantum density functional theory methods are applied for the calculation of infrared spectra of Ca4Si4O14H4, Ca6Si3O13H2, and Ca12Si6O26H4 clusters. We find bands distributed over the near, mid and far-infrared region. A specific calcium-silicate-hydrate spectral feature at 14 microns, together with the bands at 10 and 18 microns which exist for other silicates as well, could be used for a detection of cosmic cement. We compare calculated bands with the 14 microns features in the spectra of HD 45677, HD 44179, and IRC+10420 which were observed by Infrared Space Observatory and classified as remaining. High abundance of oxygen atoms in cementitious nanoparticles could partially explain observed depletion of this element from the interstellar medium into dust grains.

description: Recent observations from {\em RHESSI} have revealed that the number of non-thermal electrons in the coronal part of a flaring loop can exceed the number of electrons required to explain the hard X-ray-emitting footpoints of the same flaring loop. Such sources cannot, therefore, be interpreted on the basis of the standard collisional transport model, in which electrons stream along the loop while losing their energy through collisions with the ambient plasma; additional physical processes, to either trap or scatter the energetic electrons, are required. Motivated by this and other observations that suggest that high energy electrons are confined to the coronal region of the source, we consider turbulent pitch angle scattering of fast electrons off low frequency magnetic fluctuations as a confinement mechanism, modeled as a spatial diffusion parallel to the mean magnetic field. In general, turbulent scattering leads to a reduction of the collisional stopping distance of non-thermal electrons along the loop and hence to an enhancement of the coronal HXR source relative to the footpoints. The variation of source size $L$ with electron energy $E$ becomes weaker than the quadratic behavior pertinent to collisional transport, with the slope of $L(E)$ depending directly on the mean free path $λ$ again pitch angle scattering. Comparing the predictions of the model with observations, we find that $λ\sim$$(10^8-10^9)$ cm for $\sim30$ keV, less than the length of a typical flaring loop and smaller than, or comparable to, the size of the electron acceleration region.

Towards optimal explicit time-stepping schemes for the gyrokinetic equations

description: The nonlinear gyrokinetic equations describe plasma turbulence in laboratory and astrophysical plasmas. To solve these equations, massively parallel codes have been developed and run on present-day supercomputers. This paper describes measures to improve the efficiency of such computations, thereby making them more realistic. Explicit Runge-Kutta schemes are considered to be well suited for time-stepping. Although the numerical algorithms are often highly optimized, performance can still be improved by a suitable choice of the time-stepping scheme, based on spectral analysis of the underlying operator. Here, an operator splitting technique is introduced to combine first-order Runge-Kutta-Chebychev schemes for the collision term with fourth-order schemes for the remaining terms. In the nonlinear regime, based on the observation of eigenvalue shifts due to the (generalized) $E\times B$ advection term, an accurate and robust estimate for the nonlinear timestep is developed. The presented techniques can reduce simulation times by factors of up to three in realistic cases. This substantial speedup encourages the use of similar timestep optimized explicit schemes not only for the gyrokinetic equation, but also for other applications with comparable properties.

description: We investigate the problem of optimally approximating a desired state by the convex mixing of a set of available states. The problem is recasted as finding the optimal state with the minimum distance from target state in a convex set of usable states. Based on the fidelity, we define the optimal convex approximation of an expected state and present the complete exact solutions with respect to an arbitrary qubit state. We find that the optimal state based on fidelity is closer to the target state than the optimal state based on trace norm in many ranges. Finally, we analyze the geometrical properties of the target states which can be completely represented by a set of practicable states. Using the feature of convex combination, we express this class of target states in terms of three available states.

description: High-performance solution-processed short-channel carbon nanotube (CNT) thin film transistors (TFTs) are fabricated using densely aligned arrays of metallic CNTs (m-CNTs) as source and drain electrodes, and aligned arrays of semiconducting enriched CNTs (s-CNTs) as channel material. The electrical transport measurements at room temperature show that the m-CNT contacted s-CNT array devices with a 2 um channel length perform superiorly to those of control Pd contacted s-CNT devices. The m-CNT contacted devices exhibit a maximum (average) on-conductance of 36.5 uS (19.2 uS), transconductance of 2.6 uS (1.2 uS), mobility of 51 cm2/Vs (25 cm2/Vs), and current on-off ratio of 1.1x10E6 (2.5x10E5). These values are almost an order of magnitude higher than that of control Pd contacted devices with the same channel length and s-CNT linear density. The low temperature charge transport measurements suggest that these improved performances are due to the lower charge injection barrier of m-CNT/s-CNT array devices compared to Pd/s-CNT array devices. We attribute the lower injection barrier to unique geometry of our devices. In addition to using semiconducting enriched CNT, our results suggest that using metallic CNT as an electrode can significantly enhance the performance of CNT TFTs.

description: The commutator $[x(t),p]$ in an inverted harmonic oscillator (IHO) in one-dimensional quantum mechanics exhibits remarkable properties. It reduces to a c-number and does not show any quantum fluctuations for arbitrary states. Related to this nature, the quantum Lyapunov exponent computed through the out-of-time-order correlator (OTOC) $\langle [x(t),p]^2 \rangle $ precisely agrees with the classical one. Hence, the OTOC may be regarded as an ideal indicator of the butterfly effect in the IHO. Since IHOs are ubiquitous in physics, these properties of the commutator $[x(t),p]$ and the OTOCs might be seen in various situations, too. In order to clarify this point, as a first step, we investigate OTOCs in one-dimensional quantum mechanics with polynomial potentials, which exhibit butterfly effects around the peak of the potential in classical mechanics. We find two situations in which the OTOCs show exponential growth reproducing the classical Lyapunov exponent of the peak. The first one, which is obvious, is using a suitably localized wave packet near the peak, and the second one is taking a limit akin to the large-$N$ limit in the noncritical string theories.

description: The interaction of fluid membranes with a scaffold, which can be a planar surface or a more complex structure, is intrinsic to a number of systems - from artificial supported bilayers and vesicles to cellular membranes. In principle, these interactions can be either discrete and protein mediated, or continuous. In the latter case, they emerge from ubiquitous intrinsic surface interaction potentials as well as nature-designed steric contributions of the fluctuating membrane or from the polymers of the glycocalyx. Despite the fact that these nonspecific potentials are omnipresent, their description has been a major challenge from experimental and theoretical points of view. Here we show that a full understanding of the implications of the continuous interactions can be achieved only by expanding the standard superposition models commonly used to treat these types of systems, beyond the usual harmonic level of description. Supported by this expanded theoretical framework, we present three independent, yet mutually consistent, experimental approaches to measure the interaction potential strength and the membrane tension. Upon explicitly taking into account the nature of shot noise as well as of finite experimental resolution, excellent agreement with the augmented theory is obtained, which finally provides a coherent view of the behavior of the membrane in a vicinity of a scaffold.

description: Electric fields can be used to tune donor spins in silicon using the Stark shift, whereby the donor electron wave function is displaced by an electric field, modifying the hyperfine coupling between the electron spin and the donor nuclear spin. We present a technique based on dynamic decoupling of the electron spin to accurately determine the Stark shift, and illustrate this using antimony donors in isotopically purified silicon-28. We then demonstrate two different methods to use a DC electric field combined with an applied resonant radio-frequency (RF) field to conditionally control donor nuclear spins. The first method combines an electric-field induced conditional phase gate with standard RF pulses, and the second one simply detunes the spins off-resonance. Finally, we consider different strategies to reduce the effect of electric field inhomogeneities and obtain above 90% process fidelities.

description: Cold nuclear matter (CNM) effects provide an important baseline for the interpretation of data in heavy ion collisions. Such effects include nuclear shadowing, Cronin effect, and initial patron energy loss, and it is interesting to study the dependence on impact parameter and kinematic region. Heavy quark production is a good measurement to probe the CNM effects particularly on gluons, since heavy quarks are mainly produced via gluon fusions at RHIC energy. The PHENIX experiment has experiment has ability to study the CNM effects by measuring heavy quark production in $d$$+$Au collisions at variety of kinematic ranges. Comparisons of heavy quark production at different rapidities allow us to study modification of gluon density function in the Au nucleus depending on momentum fraction. Furthermore, comparisons to the results from heavy ion collisions (Au$+$Au and Cu$+$Cu) measured by PHENIX provide insight into the role of CNM effects in such collisions. Recent PHENIX results on heavy quark production are discussed.

JOB PACKING: OPTIMIZED CONFIGURATION FOR JOB SCHEDULING
Creators: name: Dal Pra, Stefano
Publisher: name: INFN Open Access Repository
Year: 2014

description: The default behaviour of a batch system is to dispatch jobs to nodes having the lower
 value of some load index. Whilst this causes jobs to be equally distributed among all the
 nodes in the farm, there are cases when different types of behaviour may be desirable, such as
 having a completely full node before dispatching jobs to another one, or having similar jobs
 dispatched to nodes already running jobs of the same kind. This work defines the packing
 concept, different packing policies and useful metrics to evaluate how good the policy is. A
 simple farm simulator has been written to evaluate the expected impact on a farm of different
 packing policy. The simulator is run against a sequence of real jobs, whose parameters have
 been taken from the accounting database of INFN-Tier1. The effectiveness of two packing
 policies of interest, namely relaxed and exclusive, are compared. The exclusive policy proves
 to be better, at the cost of unused cores in the farm, whose number is estimated. The
 possibility of implementing the exclusive policy on a specific batch system, LSF 7.06, is
 exploited. Relevant configurations are shown and an overall description of the mechanism is
 presented.

description: For $G=G_{n, 1/2}$, the Erdős--Renyi random graph, let $X_n$ be the random variable representing the number of distinct partitions of $V(G)$ into sets $A_1, \ldots, A_q$ so that the degree of each vertex in $G[A_i]$ is divisible by $q$ for all $i\in[q]$. We prove that if $q\geq 3$ is odd then $X_n\xrightarrow{d}{\mathrm{Po}(1/q!)}$, and if $q \geq 4$ is even then $X_n\xrightarrow{d}{\mathrm{Po}(2^q/q!)}$. More generally, we show that the distribution is still asymptotically Poisson when we require all degrees in $G[A_i]$ to be congruent to $x_i$ modulo $q$ for each $i\in[q]$, where the residues $x_i$ may be chosen freely. For $q=2$, the distribution is not asymptotically Poisson, but it can be determined explicitly.

description: The administration of President Donald Trump has changed the focus of the international trade policy of the United States from fostering trade liberalization through multilateral reciprocity to countering unfair and nefarious trade practices of foreign firms, state owned enterprises and governments. Concerns of countries regarding unfair and nefarious international trade practices has a long trade policy history and actions to deal with it are known in the United States Congress as aggressive unilateralism. This paper argues that in the period between the two world wars the focus of trade policy concerns shifted to trade restrictions imposed by governments. After the Great Depression and the Second World War those putting in place multilateral institutions to deal with trade problems focused exclusively on tariffs and trade barriers imposed by governments and made no provisions for governments to act against what they perceive as unfair and nefarious international trade practices of trading partners. Trade liberalization through multilateral reciprocity became the ruling paradigm of international trade policy and was accepted by most governments and all US administrations from Truman through to Obama – although aggressive unilateralism was manifest in the United States Congress. The Trump administration eschews the ruling paradigm and actively practices its own brand of aggressive unilateralism, although it does not use the term but rather wishes to make it part of the president’s brand. Multilateral trade institutions need to find the means to retain the benefits of liberalization based on multilateral reciprocity while incorporating mechanisms to allow governments to deal with unfair and nefarious international trade practices.

description: Citations are a conceptual directional link from citing entities to cited entities, with the purpose of acknowledging other works. Such citations are a core part of scholarly communication, which involves the flow of information and ideas through the citation network, for the benefit of the scholarly endeavour as a whole. Often, citations have also been used as one of the proxies to measure the impact of research outputs, people and institutions, for instance in research assessment exercises. The open availability of citation data is a crucial requirement to enable reproducibility in bibliometrics and scientometrics research. In addition, it is a crucial requirement for guaranteeing transparency for research assessment purposes, since they allow even those evaluated to verify their assessments according to the source data.
However, currently research assessment is affected by an overall lack of transparency of the methods in use, and the scholarly community has to strive to put to commons citation and bibliographic data that cannot be copyrighted. Since its foundation in 2010, OpenCitations has been established as an independent, community-led, and not-for-profit Open Science infrastructure with the mission to harvest and openly publish accurate and comprehensive metadata describing the world's academic publications and the scholarly citations that link them, and to preserve ongoing access to this information by secure archiving. OpenCitations enables the creation of reproducible metrics for research assessment exercises by providing open citation metadata, and develops and shares open-source software and open services. OpenCitations' commitment to Open Science has been fostered also through numerous collaborations with other Open Science actors, including OpenAIRE and the Global Sustainability Coalition for Open Science Services (SCOSS), which in 2019 selected OpenCitations as an innovative service with the potential to support change in research assessment. Currently, the OpenCitations collections contain more than 2.6 billion indexed records, and it keeps growing, always remaining loyal to its principles and values, and with the priority to keep its services, software and data always without charge under open licenses for fostering maximum reuse.

description: let $\widetilde{\bf U}^\imath$ be a quasi-split universal $\imath$quantum group associated to a quantum symmetric pair $(\widetilde{\bf U}, \widetilde{\bf U}^\imath)$ of Kac-Moody type with a diagram involution $τ$. We establish the Serre-Lusztig relations for $\widetilde{\bf U}^\imath$ associated to a simple root $i$ such that $i \neq τi$, complementary to the Serre-Lusztig relations associated to $i=τi$ which we obtained earlier. A conjecture on braid group symmetries on $\widetilde{\bf U}^\imath$ associated to $i$ disjoint from $τi$ is formulated.

description: We demonstrate that Appell-Lerch sums with higher order poles as well as their modular covariant completions arise as partition functions in the cigar conformal field theory with worldsheet supersymmetry. The modular covariant derivatives of the elliptic genus of the cigar give rise to operator insertions corresponding to (powers of) right-moving momentum, left-moving fermion number, as well as a term corresponding to an ordinary zero mode partition sum. To show this, we demonstrate how the right-moving supersymmetric quantum mechanics (and in particular the Hamiltonian and spectral density) depend on the imaginary part of the chemical potential for angular momentum. As a consequence of our analysis we find that varying the imaginary part of the chemical potential for angular momentum on the cigar gives rise to a wall-crossing phenomenon in the bound state contribution to the elliptic genus, while the full elliptic genus is a continuous function of the chemical potential.

description: The design of aircraft collision avoidance algorithms is a subtle but important challenge that merits the need for provable safety guarantees. Obtaining such guarantees is nontrivial given the unpredictability of the interplay of the intruder aircraft decisions, the ownship pilot reactions, and the subtlety of the continuous motion dynamics of aircraft. Existing collision avoidance systems, such as TCAS and the Next-Generation Airborne Collision Avoidance System ACAS X, have been analyzed assuming severe restrictions on the intruder's flight maneuvers, limiting their safety guarantees in real-world scenarios where the intruder may change its course. This work takes a conceptually significant and practically relevant departure from existing ACAS X models by generalizing them to hybrid games with first-class representations of the ownship and intruder decisions coming from two independent players, enabling significantly advanced predictive power. By proving the existence of winning strategies for the resulting Adversarial ACAS X in differential game logic, collision-freedom is established for the rich encounters of ownship and intruder aircraft with independent decisions along differential equations for flight paths with evolving vertical/horizontal velocities. We present three classes of models of increasing complexity: single-advisory infinite-time models, bounded time models, and infinite time, multi-advisory models. Within each class of models, we identify symbolic conditions and prove that there then always is a possible ownship maneuver that will prevent a collision between the two aircraft.

description: Systematic uncertainties that have been subdominant in past large-scale structure (LSS) surveys are likely to exceed statistical uncertainties of current and future LSS data sets, potentially limiting the extraction of cosmological information. Here we present a general framework (PCA marginalization) to consistently incorporate systematic effects into a likelihood analysis. This technique naturally accounts for degeneracies between nuisance parameters and can substantially reduce the dimension of the parameter space that needs to be sampled. As a practical application, we apply PCA marginalization to account for baryonic physics as an uncertainty in cosmic shear tomography. Specifically, we use CosmoLike to run simulated likelihood analyses on three independent sets of numerical simulations, each covering a wide range of baryonic scenarios differing in cooling, star formation, and feedback mechanisms. We simulate a Stage III (Dark Energy Survey) and Stage IV (Large Synoptic Survey Telescope/Euclid) survey and find a substantial bias in cosmological constraints if baryonic physics is not accounted for. We then show that PCA marginalization (employing at most 3 to 4 nuisance parameters) removes this bias. Our study demonstrates that it is possible to obtain robust, precise constraints on the dark energy equation of state even in the presence of large levels of systematic uncertainty in astrophysical processes. We conclude that the PCA marginalization technique is a powerful, general tool for addressing many of the challenges facing the precision cosmology program.

description: В статье подчеркивается, что в соответствии с действующим Земельным кодексом Российской Федерации основными формами платы за землю являются земельный налог (до введения в действие налога на недвижимость) и плата за аренду земли. В свою очередь отмечается, что все виды платы за землю в своей первоначальной основе опираются на данные кадастровой, рыночной или нормативной стоимости земельных участков. Способы расчета размера арендной платы, а также порядок, условия и сроки ее внесения за земельные участки, находящиеся в собственности Российской Федерации и расположенные на ее территории, определяют Правила определения размера арендной платы, а также порядка, условий и сроков внесения арендной платы за земли, находящиеся в собственности Российской Федерации. В соответствии с Правилами и методиками размер платы за землю определяется федеральными органами исполнительной власти, осуществляющими в отношении таких земельных участков полномочия собственника, если иное не установлено федеральными законами, одним из следующих способов: на основании кадастровой стоимости земельных участков; по результатам торгов; в соответствии со ставками арендной платы либо методическими указаниями по ее расчету, утвержденными Министерством экономического развития Российской Федерации; на основании рыночной стоимости земельных участков, определяемой в соответствии с законодательством Российской Федерации об оценочной деятельности. В данной статье представлены особенности определения годовой арендной платы земельных участков с различным целевым использованием в целях заключения договора аренды: земельных участков под строительство многоквартирного и индивидуального жилого дома.

description: Afrotheria is a diverse clade in terms of morphofunction and ecology. Although its phylogeny is well supported by molecular data, morphological and ontogenetic analyses are still demanded. This holds especially true for cranial structures that can also provide a deeper insight into sensory and ecological adaptations e.g., the ethmoidal region that houses the sense of smell as well as structures involved in thermoregulation. Here we provide a comparative description of the ethmoidal region of the semiaquatic tenrecoid Potamogale velox based on histological serial sections of the fetal chondrocranium and µCT data of the adult skull. The chondrocranium of Potamogale velox generally resembles the placental morphotype showing a prominent and well-developed cupula nasi anterior with a large processus alaris superior. The nasoturbinal is developing later in ontogeny. The number of olfactory turbinals is already determined before birth and shows a common pattern among small placental mammals: two frontoturbinals, three ethmoturbinals, one interturbinal between ethmoturbinal I and II. Apomorphic characters of Potamogale velox that are related to its semiaquatic mode of life are as follows: proportionally small olfactory turbinal skeleton and a reduced lamina cribrosa, loss of ductus nasolacrimalis, and an enlarged foramen epiphaniale due to the enhanced sensory innervation of the snout. Although the maxilloturbinal, that is involved in thermoregulation, is proportionally larger than in the terrestrial Tenrecoidea its morphological complexity is not significantly increasing from the fetus to the adult. Our results prove once again the importance of a deeper understanding of the cranial ontogeny for morphological studies of the mammalian skull.
