title: Recovery of lithium by ion-exchange in zeolitic materials

description: More than 70% of the global lithium resources are not solid minerals but dissolved salts within continental brines or geothermal waters. Critical issues in the exploitation of such deposit include low Li concentrations and high level of impurities that need to be discarded. One of the most important methods for Li acquisition from brines is ion-exchange. In this perspective, the use of zeolitic materials as ion-exchangers in lithium extractions can potentially represent a fast and cheap alternative to traditional methods. In ion-exchange processes, the anionic charge of the host structure is compensated by Li+ cations. Because of the high charge density, the Li+ cations can interact relatively strongly with the host framework and therefore significantly distort it. We examined this effect at the atomic scale and highlight the structural distortion upon Li-exchange in vanadosilicate zeotypes. Using X-ray diffraction, we were able to precisely locate the Li cations within the framework and characterize the structure. Differences in the position and bond energy of the cationic sites strongly affected the extent and kinetics of the cation exchange. Thus, we observe Li+ exclusion at specific exchange sites. This appears to be directly linked to the coordination requirements of the Li-cations with the framework oxygen atoms. Our findings might contribute to a rational design and functionalization of zeolitic material to efficiently extract lithium from brines.

description: We introduce a two-parameter family of birational maps, which reduces to a family previously found by Demskoi, Tran, van der Kamp and Quispel (DTKQ) when one of the parameters is set to zero. The study of the singularity confinement pattern for these maps leads to the introduction of a tau function satisfying a homogeneous recurrence which has the Laurent property, and the tropical (or ultradiscrete) analogue of this homogeneous recurrence confirms the quadratic degree growth found empirically by Demskoi et al. We prove that the tau function also satisfies two different bilinear equations, each of which is a reduction of the Hirota-Miwa equation (also known as the discrete KP equation, or the octahedron recurrence). Furthermore, these bilinear equations are related to reductions of particular two-dimensional integrable lattice equations, of discrete KdV or discrete Toda type. These connections, as well as the cluster algebra structure of the bilinear equations, allow a direct construction of Poisson brackets, Lax pairs and first integrals for the birational maps. As a consequence of the latter results, we show how each member of the family can be lifted to a system that is integrable in the Liouville sense, clarifying observations made previously in the original DTKQ case.

description: We report all phases and corresponding critical lines of the quantum anisotropic transverse XY model with Dzyaloshinskii-Moriya (DM) interaction along with uniform and alternating transverse magnetic fields (ATXY) by using appropriately chosen order parameters. We prove that when DM interaction is weaker than the anisotropy parameter, it has no effect at all on the zero-temperature states of the XY model with uniform transverse magnetic field which is not the case for the ATXY model. However, when DM interaction is stronger than the anisotropy parameter, we show appearance of a new gapless phase - a chiral phase - in the XY model with uniform as well as alternating field. We further report that first derivatives of nearest neighbor two-site entanglement with respect to magnetic fields can detect all the critical lines present in the system. We also observe that the factorization surface at zero-temperature present in this model without DM interaction becomes a volume on the introduction of the later. We find that DM interaction can generate bipartite entanglement sustainable at large times, leading to a proof of ergodic nature of bipartite entanglement in this system, and can induce a transition from non-monotonicity of entanglement with temperature to a monotonic one.

description: Mixed action lattice QCD with Borici-Creutz valence quarks on staggered sea is investigated. The counter terms in Borici-Creutz action are fixed nonperturbatively to restore the broken parity and time symmetries. On symmetry restoration, the usual signatures of partial quenching / unitarity violation like negative scalar correlator are observed. The size of unitarity violation due to different discretization of valence and sea quark is determined by measuring $Δ_{\rm mix}$ and is found to be comparable with other mixed action studies.

description: Vaccinium praestans, или красника, — кустарничек, представитель семейства Вересковые (Ericaceae), узкий эндемик Дальнего Востока, представляющий практический интерес как сырьевой источник природных антиоксидантов. Данное исследование позволило выявить зависимость содержания аскорбиновой кислоты и антоцианов в соке из плодов красники (Vaccinium praestans) от изменения температуры, количества солнечных дней, количества осадков, собранного на полуострове Камчатка. Определение содержания аскорбиновой кислоты в соках из плодов красники выполнялось методом капиллярного электрофореза со спектрофотометрическим детектированием при l = 254 нм, а суммы антоцианов — методом рН-дифференциальной спектрофотометрии при l = 510 нм. Коэффициент корреляции был рассчитан по методу Пирсона. В результате исследования была определена высокая корреляционная зависимость между накоплением аскорбиновой кислоты в плодах красники и количеством солнечных дней (r = 0,98), суммой активных температур (r = 0,89), а также между содержанием антоцианов в плодах красники и количеством осадков (r = 0,88). Установлено, что вегетация красники в условиях теплой солнечной погоды способствует высокому накоплению аскорбиновой кислоты, а обильные осадки и облачная погода благоприятствуют синтезу антоцианов в плодах красники.

В картине обращений и госпитализаций у населения отмечена выраженная сезонность, которая соотносится с высокой погодной контрастностью и существенным вкладом аэрогенных поллютантов в уровень загрязнения атмосферного воздуха, чувствительность такой взаимосвязи сопровождалась статистически значимыми корреляционными коэффициентами. Установлена высокая степень взаимосвязи экологически обусловленных заболеваний органов дыхания у жителей урбанизированного города с атмосферными загрязнителями по комплексному индексу. Выявлена возрастная группа лиц трудоспособного населения (среднего возраста), т.н. группа повышенного риска, с признаками развития и рецидива климаточувствительных и экологически обусловленных болезней, что бесспорно подтверждает существование взаимосвязи погодных условий с высокой степенью риска обострений или развития климаточувствительных болезней.

description: Three new graph invariants are introduced which may be measured from a quantum graph state and form examples of a framework under which other graph invariants can be constructed. Each invariant is based on distinguishing a different number of qubits. This is done by applying alternate measurements to the qubits to be distinguished. The performance of these invariants is evaluated and compared to classical invariants. We verify that the invariants can distinguish all non-isomorphic graphs with 9 or fewer nodes. The invariants have also been applied to `classically hard' strongly regular graphs, successfully distinguishing all strongly regular graphs of up to 29 nodes, and preliminarily to weighted graphs. We have found that although it is possible to prepare states with a polynomial number of operations, the average number of preparations required to distinguish non-isomorphic graph states scales exponentially with the number of nodes. We have so far been unable to find operators which reliably compare graphs and reduce the required number of preparations to feasible levels.

description: Using $e^+e^-$ annihilation data taken at the CESR collider with the CLEO-c detector, measurements of hyperon pair production cross sections and elastic and transition electromagnetic form factors have been made at the charmonium resonances: $ψ(2S)$, $\sqrt{s}=3.69$ GeV, $|Q^2|=13.6$ GeV$^2$, $\mathcal{L}=48$~pb$^{-1}$; $ψ(3770)$, $\sqrt{s}=3.77$ GeV, $|Q^2|=14.2$ GeV$^2$, $\mathcal{L}=805$~pb$^{-1}$; and $ψ(4170)$, $\sqrt{s}=4.17$ GeV, $|Q^2|=17.4$ GeV$^2$, $\mathcal{L}=586$~pb$^{-1}$. %High efficiency particle identification has resulted in good statistical precision in the results. Results with good statistical precision are obtained with high efficiency particle identification. Systematics of pair production cross sections, and form factors with respect to the number of strange quarks in the hyperons are studied, and evidence is presented for effects of diquark correlations in comparative results for $Λ^0$ and $Σ^0$, both of which have the same $uds$ quark content.

description: Objectives: Exact symmetry and perfect balance between opposite jaw halves, as well as between antagonistic teeth, is not frequently observed in natural masticatory systems. Research results show that asymmetry in our body, skull, and jaws is often related to genetic, epigenetic, environmental and individual ontogenetic factors. Our study aims to provide evidence for a significant link between masticatory asymmetry and occlusal contact between antagonist teeth by testing the hypothesis that tooth inclination is one of the mechanisms driving distribution of wear in masticatory phases in addition to dietary and cultural habits. Materials and Methods: The present work investigates the relationship between dental macrowear patterns and tooth inclinations on a sample of complete maxillary and mandibular 3D models of dental arches from 19 young and adult Yuendumu Aboriginal individuals. The analysis was carried out on first molars (M1) from all quadrants. Occlusal Fingerprint Analysis was used for the quantification of macrowear patterns, and 2D cross-sectional geometric analysis was carried out to investigate asymmetry in dental arches.Results: The asymmetry is highly variable on both arches, and it is associated with differences in theinclination of upper M1 crowns. Each molar has variable inclination (buccal/lingual) which influencetooth to tooth contact, producing greater or lesser variation in wear pattern. Interindividual variabilityof morphological variation of the occlusal relationship has to be considered in macrowear analysis.Discussion: Our results suggest that overall asymmetry in the masticatory apparatus in modernhumans affects occlusal contact areas between antagonist teeth influencing macrowear and chewingefficiency during ontogeny.

description: A common paradigm used in the construction of equations of state is to decompose the thermodynamics into a superposition of three terms: a static-lattice cold curve, a contribution from the thermal motion of the nuclei, and a contribution from the thermal excitation of the electrons. While statistical mechanical models for crystals provide tractable framework for the nuclear contribution in the solid phase, much less is understood about the nuclear contribution above the melt temperature ($C_v^{(\text{nuc})}\approx 3R$) and how it should transition to the high-temperature limit ($C_v^{(\text{nuc})} \sim \frac{3}{2}R$). In this work, we describe an algorithm for extracting both the thermal nuclear and thermal electronic contributions from quantum molecular dynamics (QMD). We then use the VASP QMD package to probe thermal nuclear behavior of liquid aluminum at normal density to compare the results to semi-empirical models -- the Johnson generic model, the Chisolm high-temperature liquid model, and the CRIS model.

description: Employing an integrated approach to investigate the use of Late Lower Paleolithic flint tools found at the site of Qesem Cave (Israel), we revealed a particular trace pattern related to the employment of ashes at the site. Using a designated collection of replica items and combining use-wear and residue (morphological analysis, FTIR, SEM-EDX) analyses, we revealed the intentional use of ashes in preserving foods for delayed consumption as well as hide for delayed processing. Our interpretation, we believe is the most plausible one since we were able to delineate the specific use-wear fingerprints of the intentional use of ashes for such purposes, suggesting that our approach might be useful for the recognition of other similar functional-behavioral patterns. Lastly, in support of previous findings at Qesem Cave, our current findings present evidence for the processing of organic matters intentionally mixed with ash, leading us to suggest that the inhabitants of Qesem Cave were proficient not only in the habitual use of fire but also of its main by-product, ash. Hence, we call for a reassessment of the timeline currently assigned to hominins’ utilization of ash for storing and processing vegetal foods and hide.

description: We introduce two- and one-dimensional (2D and 1D) systems of two linearly-coupled Gross-Pitaevskii equations (GPEs) with the cubic self-attraction and harmonic-oscillator (HO) trapping potential in each GPE. The system models a Bose-Einstein condensate with a negative scattering length, loaded in a double-pancake trap, combined with the in-plane HO potential. In addition to that, the 1D version applies to the light transmission in a dual-core waveguide with the Kerr nonlinearity and in-core confinement represented by the HO potential. The subject of the analysis is spontaneous symmetry breaking in 2D and 1D ground-state (GS, alias fundamental) modes, as well as in 2D vortices and 1D dipole modes (the latter ones do not exist without the HO potential). By means of the variational approximation and numerical analysis, it is found that both the 2D and 1D systems give rise to a symmetry-breaking bifurcation (SBB) of the supercrtical type. Stability of symmetric states and asymmetric ones, produced by the SBB, is analyzed through the computation of eigenvalues for perturbation modes, and verified by direct simulations. The asymmetric GSs are always stable, while the stability region for vortices shrinks and eventually disappears with the increase of the linear-coupling constant, $ κ$. The SBB in the 2D system does not occur if $κ$ is too large (at $κ>κ_{\max }$); in that case, the two-component system behaves, essentially, as its single-component counterpart. In the 1D system, both asymmetric and symmetric dipole modes feature an additional oscillatory instability, unrelated to the symmetry breaking. This instability occurs in several regions, which expand with the increase of $κ$.

Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions.

description: In recent years, several works have proved the reliability of the application of 3D modeling and spatial analysis in the study of stone tool use. Monitoring surface morphometry resulting from the use of lithic tools has the potential to objectively quantify and identify patterns of modifications associated to specific activities and worked materials. In particular, the combination of surface morphometry with a systematic experimental framework and use wear analysis has the potential of foreseeing residue distribution areas over the groundstone surfaces, hence providing a key aid in establishing sampling strategies applied to archeological specimens. Here, we propose an approach that applies 3D modeling, performed through a close-range photogrammetry, andì the use of GIS software to investigate surface modifications and residue distribution on groundstones used to process wild plants. Our work comprises a dedicated experimental framework in which modern tool replicas have been used to process different species of wild plant foods through grinding, crushing, and pounding. By applying 3D modeling and spatial analysis, we wereì able to characterize patterns of surface modifications related to each of the worked substances and activities performed. Moreover, we monitored the distribution of starch granules over the experimental groundstone surfaces and its variation in relation to the state of the worked substance and the action carried out. Our results provide one of the first experimental dataset focused on the use of groundstones for wild plant processing, and a reliable methodology for further studies related to the exploitation of stone technology and wild vegetal substances in the past.

description: We investigated Lorentz violation through anisotropy of gravity using a worldwide array of 12 superconducting gravimeters. The Lorentz-violating signal is extracted from the difference between measured gravity and a tidal model. At the level of sensitivity we reach, ocean tides start to play an important role. However, most models available that include ocean tides are empirically based on measured gravity data, which may contain Lorentz-violating signal. In this work we used an ocean tides included tidal model derived from first principles to extract Lorentz-violating signal for the first time. We have bounded space-space components of gravitational Lorentz violation in the minimal standard model extension (SME) up to the order of $10^{-10}$, one order of magnitude improved relative to previous atom-interferometer tests.

description: Laser-plasma accelerators (LPAs), producing high-quality electron beams, provide an opportunity to reduce the size of free-electron lasers (FELs) to only a few meters. A complete system is proposed here, which is based on FEL technology and consists of an LPA, two undulators, and other magnetic devices. The system is capable to generate carrier-envelope phase stable attosecond pulses with engineered waveform. Pulses with up to~60~nJ energy and 90 to~400~attosecond duration in the 30 to 120~nm wavelength range are predicted by numerical simulation.

description: Virtual histology is increasingly utilized to reconstruct the cell mechanisms underlying dental morphology for fragile fossils when physical thin sections are not permitted. Yet, the comparability of data derived from virtual and physical thin sections is rarely tested. Here, the results from archaeological human deciduous incisor physical sections are compared with virtual ones obtained by phase-contrast synchrotron radiation computed microtomography (SRmCT) of intact specimens using a multi-scale approach. Moreover, virtual prenatal daily enamel secretion rates are compared with those calculated from physical thin sections of the same tooth class from the same archaeological skeletal series. Results showed overall good visibility of the enamel microstructures in the virtual sections which are comparable to that of physical ones. The highest spatial resolution SRmCT setting (effective pixel size = 0.9 mm) produced daily secretion rates that matched those calculated from physical sections. Rates obtained using the lowest spatial resolution setup (effective pixel size = 2.0 mm) were higher than those obtained from physical sections. The results demonstrate that virtual histology can be applied to the investigated samples to obtain reliable and quantitative measurements of prenatal daily enamel secretion rates

description:
 Ornaments are polysemic objects due to different meanings they convey in human societies—self-embellishment, means of exchange, markers of age and gender, indicators of social status, signs of power, non-verbal means of expression and communication. Beads have a privileged place in shedding light on the origins of modern cognition in human societies. While archaeological approaches to ancient symbolism have often been concerned with behavioral modernity of our species, anthropological studies have underlined the role of ornaments in the construction of personhood, identity, and social networks in traditional societies. Exploring an approach informed by anthropological and ethnographic theory, we discuss Paleolithic and Mesolithic bodily adornments found across southeastern Europe. We present a review of the evidence for long-term regional and diachronic differences and similarities in types of body adornment among prehistoric foragers of the region. Here we look at aspects of cultural transmission and transferability over time. This enables us to reconstruct a series of gestures involved in ornament manufacture and use, and to examine transmissions of technological know-hows, shifting aesthetic values, and demands for specific local and non-local materials, including marine shells transferred across this region over long distances (>400km). This evidence is further discussed by, on the one hand, taking a perspective that draws on emic understandings of ornaments in certain ethnographic contexts and, on the other hand, through a rethinking of the relevance of the structural anthropological mode of analysis championed by Lévi-Strauss.

Abstract: Die Notwendigkeit und Dringlichkeit einer nachhaltigen Entwicklung nehmen zu. Dadurch sind verschiedene Institutionen, Unternehmen und Organisationen gezwungen, sich an die aktuelle Entwicklung anzupassen und Lösungsansätze zu erarbeiten. Die Bandbreite an Herausforde-rungen ist in diesem Zusammenhang beträchtlich. Die hinsichtlich des Klimawandels hervor-gehende Veränderung in der Niederschlagsverteilung und der Temperaturanstieg führen in der Schweiz im Sommer zu längeren Hitze- und Dürreperioden. Diese Entwicklung wirft die Frage nach der Zukunft des Wasserressourcenmanagements auf. In diesem Kontext rückt auch der Golfplatz als bedeutender Verbraucher von Wasser in den Fokus. Eine gründliche Analyse der Schweizer Golfplätze bezüglich ihres Wasserverbrauchs wird in der Zukunft unumgänglich sein. In dieser Arbeit wird eine umfassende Darstellung der für die Bewässerung relevanten Komponenten vorgenommen und am Beispiel des Kantons Wallis mit seinen acht Golfplätzen illustriert.

description: In 2012, five high school students involved in the Pulsar Search Collaboratory discovered the millisecond pulsar PSR J1400$-$1431 and initial timing parameters were published in Rosen et al. (2013) a year later. Since then, we have obtained a phase-connected timing solution spanning five years, resolving a significant position discrepancy and measuring $\dot{P}$, proper motion, parallax, and a monotonic slope in dispersion measure over time. Due to PSR J1400$-$1431's proximity and significant proper motion, we use the Shklovskii effect and other priors to determine a 95% confidence interval for PSR J1400$-$1431's distance, $d=270^{+130}_{-80}$ pc. With an improved timing position, we present the first detection of the pulsar's low-mass white dwarf (WD) companion using the Goodman Spectrograph on the 4.1-m SOAR telescope. Deeper imaging suggests that it is a cool DA-type WD with $T_{\rm eff}=3000\pm100$ K and $R/R_\odot=(2.19\pm0.03)\times10^{-2}\,(d/270\,{\rm pc})$. We show a convincing association between PSR J1400$-$1431 and a $γ$-ray point source, 3FGL J1400.5$-$1437, but only weak (3.3-$σ$) evidence of pulsations after folding $γ$-ray photons using our radio timing model. We detect an X-ray counterpart with XMM-Newton but the measured X-ray luminosity ($1\times10^{29}$ ergs s$^{-1}$) makes PSR J1400$-$1431 the least X-ray luminous rotation-powered millisecond pulsar (MSP) detected to date. Together, our findings present a consistent picture of a nearby ($d\approx230$ pc) MSP in a 9.5-day orbit around a cool, $\sim$0.3 M$_\odot$ WD companion, with orbital inclination, $i\gtrsim60^\circ$.

description: By means of first-principles calculations, we investigate the thermal properties of silica as it evolves, under hydrostatic compression, from a stishovite phase into a CaCl$_2$-type structure. We compute the thermal conductivity tensor by solving the linearized Boltzmann transport equation iteratively in a wide temperature range, using for this the pressure-dependent harmonic and anharmonic interatomic couplings obtained from first principles. Most remarkably, we find that, at low temperatures, SiO$_2$ displays a large peak in the in-plane thermal conductivity and a highly anisotropic behavior close to the structural transformation. We trace back the origin of these features by analyzing the phonon contributions to the conductivity. We discuss the implications of our results in the general context of continuous structural transformations in solids, as well as the potential geological interest of our results for silica.

description: This paper provides results from a suite of analyses made on human dental material from the Late Palaeolithic to Neolithic strata of the cave site of Grotta Continenza situated in the Fucino Basin of the Abruzzo region of central Italy. The available human remains from this site provide a unique possibility to study ways in which forager versus farmer lifeways affected human odonto-skeletal remains. The main aim of our study is to understand palaeodietary patterns and their changes over time as reflected in teeth. These analyses involve a review of metrics and oral pathologies, micro-fossils preserved in the mineralized dental plaque, macrowear, and buccal microwear. Our results suggest that these complementary approaches support the assumption about a critical change in dental conditions and status with the introduction of Neolithic foodstuff and habits. However, we warn that different methodologies applied here provide data at different scales of resolution for detecting such changes and a multipronged approach to the study of dental collections is needed for a more comprehensive and nuanced understanding of diachronic changes.
Modern theory of magnetic breakdown

description: The modern semiclassical theory of a Bloch electron in a magnetic field encompasses the orbital magnetization and geometric phase. Beyond this semiclassical theory lies the quantum description of field-induced tunneling between semiclassical orbits, known as magnetic breakdown. Here, we synthesize the modern semiclassical notions with quantum tunneling -- into a single Bohr-Sommerfeld quantization rule that is predictive of magnetic energy levels. This rule is applicable to a host of topological solids with \emph{unremovable} geometric phase, that also \emph{unavoidably} undergo breakdown. A notion of topological invariants is formulated that nonperturbatively encode tunneling, and is measurable in the de-Haas-van-Alphen effect. Case studies are discussed for topological metals near a metal-insulator transition and over-tilted Weyl fermions.

description: The automation of posterior inference in Bayesian data analysis has enabled experts and nonexperts alike to use more sophisticated models, engage in faster exploratory modeling and analysis, and ensure experimental reproducibility. However, standard automated posterior inference algorithms are not tractable at the scale of massive modern datasets, and modifications to make them so are typically model-specific, require expert tuning, and can break theoretical guarantees on inferential quality. Building on the Bayesian coresets framework, this work instead takes advantage of data redundancy to shrink the dataset itself as a preprocessing step, providing fully-automated, scalable Bayesian inference with theoretical guarantees. We begin with an intuitive reformulation of Bayesian coreset construction as sparse vector sum approximation, and demonstrate that its automation and performance-based shortcomings arise from the use of the supremum norm. To address these shortcomings we develop Hilbert coresets, i.e., Bayesian coresets constructed under a norm induced by an inner-product on the log-likelihood function space. We propose two Hilbert coreset construction algorithms---one based on importance sampling, and one based on the Frank-Wolfe algorithm---along with theoretical guarantees on approximation quality as a function of coreset size. Since the exact computation of the proposed inner-products is model-specific, we automate the construction with a random finite-dimensional projection of the log-likelihood functions. The resulting automated coreset construction algorithm is simple to implement, and experiments on a variety of models with real and synthetic datasets show that it provides high-quality posterior approximations and a significant reduction in the computational cost of inference.
