description: Solution dispersions of two-dimensional (2D) black phosphorus (BP), often referred to as phosphorene, are achieved by solvent exfoliation. These pristine, electronic-grade BP dispersions are produced with anhydrous, organic solvents in a sealed tip ultrasonication system, which circumvents BP degradation that would otherwise occur via solvated oxygen or water. Among conventional solvents, n-methyl-pyrrolidone (NMP) is found to provide stable, highly concentrated (~0.4 mg/mL) BP dispersions. Atomic force microscopy, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy show that the structure and chemistry of solvent-exfoliated BP nanosheets are comparable to mechanically exfoliated BP flakes. Additionally, residual NMP from the liquid-phase processing suppresses the rate of BP oxidation in ambient conditions. Solvent-exfoliated BP nanosheet field-effect transistors (FETs) exhibit ambipolar behavior with current on/off ratios and mobilities up to ~10000 and ~50 cm^2/(V*s), respectively. Overall, this study shows that stable, highly concentrated, electronic-grade 2D BP dispersions can be realized by scalable solvent exfoliation, thereby presenting opportunities for large-area, high-performance BP device applications.

description: Entangling gates are an essential component of quantum computers. However, generating high-fidelity gates, in a scalable manner, remains a major challenge in all quantum information processing platforms. Accordingly, improving the fidelity and robustness of these gates has been a research focus in recent years. In trapped ions quantum computers, entangling gates are performed by driving the normal modes of motion of the ion chain, generating a spin-dependent force. Even though there has been significant progress in increasing the robustness and modularity of these gates, they are still sensitive to noise in the intensity of the driving field. Here we supplement the conventional spin-dependent displacement with spin-dependent squeezing, which enables a gate that is robust to deviations in the amplitude of the driving field. We solve the general Hamiltonian and engineer its spectrum analytically. We also endow our gate with other, more conventional, robustness properties, making it resilient to many practical sources of noise and inaccuracies.

description: This paper is a step towards a version of the theta-lifting (or Howe correspondence) in the framework of the geometric Langlands program. We consider the (unramified) dual reductive pair H=GO_{2m}, G=GSp_{2n} over a smooth projective curve X (our H is assumed to be split on an etale two-sheeted covering Y of X). Let Bun_G and Bun_H be the stack of G-torsors and H-torsors on X. We define and study functors F_G and F_H between the derived categories D(Bun_G) and D(Bun_H) that are analogs of the classical theta-lifting operators. One of the main results is the geometric Langlands functoriality for the dual pair (H=GO_2, G=GL_2), where GO_2 is the direct image of the multiplicative group from a nontrivial etale covering Y to X. The functor F_G from D(Bun_H) to D(Bun_G) commutes with Hecke operators with respect to the corresponding map of Langlands L-groups G^L\to H^L. As an application, we calculate Waldspurger periods of cuspidal automorphic sheaves on Bun_{GL_2} and Bessel periods of theta-lifts from Bun_{GO_4} to Bun_{GSp_4}. Based on these calculations, we give three conjectural constructions of certain automorphic sheaves on Bun_{GSp_4} (one of them makes sense for D-modules only).

description: Breast cancer is a leading cause of cancer death among Hispanic women in the U.S., and mammography is the recommended screening for early diagnosing and preventing breast cancer. Several barriers exist to influence mammography utilization including poor health literacy. However, it is unclear whether the effect of health literacy on mammography utilization is consistent between Hispanic women and non-Hispanic White women. The main objective of this study was to examine association between functional health literacy and the receipt of mammography among Hispanic women compared to non-Hispanic White women in the U.S.

description: The predictions on the mode of decay of the odd-even and odd-odd isotopes of heavy and superheavy nuclei with Z = 99-129, in the range 228 \leg A \leg 336, have been done within the Coulomb and proximity potential model for deformed nuclei (CPPMDN). A comparison of our calculated alpha half lives with the values computed using other theoretical models shows good agreement with each other. An extensive study on the spontaneous fission half lives of all the isotopes under study has been performed to identify the long-lived isotopes in the mass region. The study reveals that the alpha decay half lives and the mode of decay of the isotopes with Z = 109, 111, 113, 115 and 117, evaluated using our formalisms, agrees well with the experimental observations. As our study on the odd-even and odd-odd isotopes of Z = 99-129 predicts that, the isotopes $^{238,240-254}$99, $^{244,246-258}$101, $^{248,250,252-260,262}$103, $^{254,256,258-262,264}$105, $^{258,260,262-264,266}$107, $^{262,264,266-274}$109, $^{266,268-279}$111, $^{270-284,286}$113, $^{272-289,291}$115, $^{274-299}$117, $^{276-307}$119, $^{281-314}$121, $^{287-320,322}$123, $^{295-325}$125, $^{302-327}$127 and $^{309-329}$129 survive fission and have alpha decay channel as the prominent mode of decay, these nuclei could possibly be synthesized in the laboratory and this could be of great interest to the experimentalists. The behaviour of these nuclei against the proton decay has also been studied to identify the probable proton emitters in this region of nuclei.

Quantum speed limit of a noisy continuous-variable system

Year: 2022
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Setting the minimal-time bound for a quantum system to evolve between two distinguishable states, the quantum speed limit (QSL) characterizes the latent capability in speeding up of the system. It has found applications in determining the quantum superiority in many quantum technologies. However, previous results showed that such a speedup capability is generally destroyed by the environment induced decoherence in the Born-Markovian approximate dynamics. We here propose a scheme to recover the speedup capability in a dissipative continuous-variable system within the exact non-Markovian framework. It is found that the formation of a bound state in the energy spectrum of the total system consisting of the system and its environment can be used to restore the QSL to its noiseless performance. Giving an intrinsic mechanism in preserving the QSL, our scheme supplies a guideline to speed up certain quantum tasks in practical continuous-variable systems.

description: I this paper, which is a sequel to math.AG/0310361, we study Bessel models of representations of GSp_4 over a local non archimedian field in the framework of the geometric Langlands program. The Bessel module over the nonramified Hecke algebra of GSp_4 admits a geometric counterpart, the Bessel category of perverse sheaves on some ind-algebraic stack. We use it to prove a geometric version of the multiplicity one for Bessel models. It implies a geometric Casselman-Shalika type formula for these models. The strategy of the proof is the same as in the paper of Frenkel, Gaitsgory and Vilonen math.AG/9907133. We also propose a geometric framework unifying Whittaker, Waldspurger and Bessel models.

Year: 2016

description: The preservation of archaeological sites in Egypt offers many perspectives of research. Not always, the immense amount of archaeological studies is balanced by an adequate attention to the material preservation. An interdisciplinary group, coordinated by the University of Florence is developing a research project on materials, building technologies and decay phenomena in different archaeological sites of Middle Egypt. The city of Antinoe is a very representative case study. The complexity of technologies and materials, along with the natural and human causes of damage, create an heterogeneous overall picture of the conservation state. The monitoring of weathering parameters and phenomena, shows many critical situations quickly evolving, in addition to manmade damage which are becoming always more serious. One of the directions of research is the study of sustainable conservation solutions that aim to renew the links between the local people and their heritage.

description: The extent to which federal investment in research crowds out or decreases incentives for investment from other funding sources remains an open question. Scholarship on research funding has focused on the relationship between federal and industry or, more comprehensively, non-federal funding without disentangling the other sources of research support that include nonprofit organizations and state and local governments. This paper extends our understanding of academic research support by considering the relationships between federal and non-federal funding sources provided by the National Science Foundation Higher Education Research and Development Survey. We examine whether federal research investment serves as a complement or substitute for state and local government, nonprofit, and industry research investment using the population of research-active academic science fields at U.S. doctoral granting institutions. We use a system of two equations that instruments with prior levels of both federal and non-federal funding sources and accounts for time-invariant academic institution-field effects through first differencing. We estimate that a 1% increase in federal research funding is associated with a 0.411% increase in nonprofit research funding, a 0.217% increase in state and local research funding, and a 0.468% increase in industry research funding, respectively. Results indicate that federal funding plays a fundamental role in inducing complementary investments from other funding sources, with impacts varying across academic division, research capacity, and institutional control.
Correlation functions of main-chain polymer nematics constrained by tensorial and vectorial conservation laws

description: We present and analyze correlation functions of a main-chain polymer nematic in a continuum worm-like chain description for two types of constraints formalized by the tensorial and vectorial conservation laws, both originating in the microscopic chain integrity, i.e., the conectivity of the polymer chains. In particular, our aim is to identify the features of the correlation functions that are most susceptible to the differences between the two constraints. Besides the density and director autocorrelations in both the tensorial and vectorial cases, we calculate also the density -- director correlation functions, the latter being a direct signature of the presence of a specific constraint. Its amplitude is connected to the strength of the constraint and is zero if none of the constraints is present, i.e., for a standard non-polymeric nematic. Generally, the correlation functions with the constraints differ substantially from the correlation functions in the non-polymeric case, if the constraints are strong which in practice requires long chains. Moreover, for the tensorial conservation law to be well distinguishable from the vectorial one, the chain persistence length should be much smaller than the total length of the chain, so that hairpins (chain backfolding) are numerous and the polar order is small.

description: In contrast with rich investigations about the translation of an antiferromagnetic (AFM) texture, spin precession in an AFM texture is seldom concerned for lacking an effective driving method. In this work, however, we show that under an alternating spin-polarized current with spin along the AFM anisotropy axis, spin precession can be excited in an AFM DW. Especially, chaotic spin precession occurs at moderate interfacial Dzyaloshinskii-Moriya interaction (DMI), which contributes to a nonlinear term in the dynamic equation of DW precession. Also, crisis-induced intermittent chaos appears when the current density is higher than a critical value. This work not only paves a way to unravel rich spin precession behaviors in an AFM texture but also provides guidelines for developing ultrafast spintronic devices based on new physical principles.

description: The authors describe the importance of the site of al-Wu’ayra, at the east border of the ancient town of Petra (Jordan) where the Archaeological Mission “Medieval Petra” (University of Florence) is working since 1986. From the archaeological point of view, the physical conformation of the site is the main condition for the formation, during nearly two thousand years, of a highly significant archaeological deposit with a continuous chronological extension from Nabataean time up to Late Islamic and a high scientific potential. On the other hand, the site itself preserves the only still standing 12th century tower of the whole area of Petra, thus being a very significant element of the historical landscape and the only monumental evidence of a short but important season of the long history of the town. During the last three decades, the addition of human disturbance to the spontaneous and natural decay of buildings makes urgent a restoration and a protection programme for the whole site.

description: Intensive research carried out at the Acropolis of the ancient Mayan city of Chilonché, which begun as a result of the fortuitous discovery in 2009 of a large zoomorphic sculpture hidden inside its basement, has revealed the great quality of its buildings, one of which retains an exceptional room decorated with murals, which was closed by the Mayas themselves at the end of the Classical period. However, the widespread archaeological looting to which the Acropolis has been subjected has greatly hampered the work of research and conservation on this remarkable cultural heritage. In this regard, the application of new documentation technologies through the use of the laser scanner and the later treatment of the information for the use of 3D techniques has allowed a detailed analysis which will help to ensure their appropriate preservation.

description: We study the dynamics of two interacting two-level systems (qubits) having one of them isolated and the other coupled to a single mode electromagnetic field in a thermal state. The field plays the role of a small environment, in contrast to the usual approach of modeling an environment via a thermal reservoir with many degrees of freedom. We find the analytical solution of the proposed model, which allows us to investigate the consequences of the coupling to the small environment on characteristic quantum features of the two-qubit system. We study the time evolution of quantum entanglement and coherence, verifying the dependence on the relevant coupling constants as well as the influence of the effective temperature of the environment. Interestingly, we find that both sudden death and sudden birth of entanglement may occur in such a simple system. We also discuss a different partition, in which the isolated qubit is considered to be coupled to a composite environment, constituted by the other qubit plus the field mode.

description: Donor spin states in silicon are a promising candidate for quantum information processing. One possible donor spin readout mechanism is the bound exciton transition that can be excited optically and creates an electrical signal when it decays. This transition has been extensively studied in bulk, but in order to scale towards localized spin readout, microfabricated structures are needed for detection. As these electrodes will inevitably cause strain in the silicon lattice, it will be crucial to understand how strain affects the exciton transitions. Here we study the phosphorous donor bound exciton transitions in silicon using hybrid electro-optical readout with microfabricated electrodes. We observe a significant zero-field splitting as well mixing of the hole states due to strain. We can model these effects assuming the known asymmetry of the hole g-factors and the Pikus-Bir Hamiltonian describing the strain. In addition, we describe the temperature, laser power and light polarization dependence of the transitions. Importantly, the hole-mixing should not prevent donor electron spin readout and using our measured parameters and numerical simulations we anticipate that hybrid spin readout in a silicon-on-insulator platform should be possible, allowing integration to silicon photonics platforms.

description: Let X be a smooth projective curve over an algebraically closed field of characteristic >2. Consider the dual pair H=SO_{2m}, G=Sp_{2n} over X with H split. Write Bun_G and Bun_H for the stacks of G-torsors and H-torsors on X. The theta-kernel on Bun_G\times Bun_H yields the theta-lifting functors between the derived categories of l-adic sheaves on Bun_G and Bun_H. We describe the relation of these functors with Hecke operators. In two particular cases it becomes the geometric Langlands functoriality for this pair (in the nonramified case). Namely, for n=m the functor from the derived category on Bun_H to that on Bun_G commutes with Hecke functors with respect to the inclusion of the Langlands dual groups SO_{2n}\to SO_{2n+1}. For m=n+1 the functor from the derived category on Bun_G to that on Bun_H commutes with Hecke functors with respect to the inclusion of the Langlands dual groups SO_{2n+1}\to \SO_{2n+2}. In other cases the relation is more complicated and involves the SL_2 of Arthur. As a step of the proof, we establish the geometric theta-lifting for the dual pair GL_m, GL_n. Our global results are derived from the corresponding local ones, which provide a geometric analog of a theorem of Rallis.

In the published version the compatibility of the functoriality isomorphisms with the tensor structure on the category of representations of the dual group was not justified.

description: Ancient floors represent one of the most significant class of artefacts for illustrating the principles of a fruitful collaboration between professionals working on archaeological excavations. One of the principal reasons for such a synergy lies upon the interdisciplinary feature of the new season of studies on ancient mosaics, as is particularly shown by the most recent conservation interventions. Aesthetic and antiquarian approaches - which for a long time have resulted in lifting mosaic panels to be exhibited as paintings in museums - have been replaced by historical-conservative approaches aimed to the conscious restitution of the formal and historical features of the artefacts. The expertise of the Soprintendenza archeologica toscana allows to provide a significant documentary evidence of the evolution of this approach, with examples spaninning from the 19th to the 21st century: from the so called “strappo a rullo”, applied the mosaics retrieved in the early nineteenth century, at Florence, in square S. Giovanni, to the increasingly numerous cases of preservation and valorization in situ of the last years.

description: Conformal inclusions of chiral conformal field theories, or more generally inclusions of quantum field theories, are described in the von Neumann algebraic setting by nets of subfactors, possibly with infinite Jones index if one takes non-rational theories into account. With this situation in mind, we study in a purely subfactor theoretical context a certain class of braided discrete subfactors with an additional commutativity constraint, that we call locality, and which corresponds to the commutation relations between field operators at space-like distance in quantum field theory. Examples of subfactors of this type come from taking a minimal action of a compact group on a factor and considering the fixed point subalgebra. We show that to every irreducible local discrete subfactor $\mathcal{N}\subset\mathcal{M}$ of type ${I\!I\!I}$ there is an associated canonical compact hypergroup (an invariant for the subfactor) which acts on $\mathcal{M}$ by unital completely positive (ucp) maps and which gives $\mathcal{N}$ as fixed points. To show this, we establish a duality pairing between the set of all $\mathcal{N}$-bimodular ucp maps on $\mathcal{M}$ and a certain commutative unital $C^*$-algebra, whose spectrum we identify with the compact hypergroup. If the subfactor has depth 2, the compact hypergroup turns out to be a compact group. This rules out the occurrence of compact \emph{quantum} groups acting as global gauge symmetries in local conformal field theory.

description: In a previous study with normal-hearing listeners, we evaluated consonant identification masked by two or more spectrally contiguous bands of noise, with asynchronous square-wave modulation applied to neighboring bands. Speech recognition thresholds were 5.1–8.5 dB better when neighboring bands were presented to different ears (dichotic) than when all bands were presented to one ear (monaural), depending on the spectral width of the frequency bands. This dichotic advantage was interpreted as reflecting masking release from peripheral spread of masking from neighboring frequency bands. The present study evaluated this effect in listeners with sensorineural hearing loss, a population more susceptible to spread of masking. Speech perception (vowel-consonant-vowel stimuli, as in /aBa/) was measured in the presence of fluctuating noise that was either modulated synchronously across frequency or asynchronously. Hearing-impaired listeners (n = 9) and normal-hearing controls were tested at either the same intensity (n = 7) or same sensation level (n = 8). Hearing-impaired listeners had mild-to-moderate hearing loss and symmetrical, flat audiometric thresholds. While all groups of listeners performed better in the dichotic than monaural condition, this effect was smaller for the hearing-impaired (3.5 dB) and equivalent-sensation-level controls (3.3 dB) than controls tested at the same intensity (11.0 dB). The present study is consistent with the idea that dichotic presentation can improve speech-in-noise listening for hearing-impaired listeners, and may be enhanced when combined with amplification.

description: We simultaneously model the gravitational potential and phase space distribution function (DF) of giant stars near the Sun using the {\it Gaia} DR2 radial velocity catalog. We assume that the Galaxy is in equilibrium and is symmetric about both the spin axis of the disk and the Galactic midplane. The potential is taken as a sum of terms that nominally represent contributions from the gas disk, stellar disk, bulge, and dark matter halo. Our DF model for the giants comprise two components to account for a mix of thin and thick disk stars. The DF for each component is described by an analytic function of the energy, the spin angular momentum, and the vertical energy, in accord with Jeans theorem. We present model predictions for the radial and vertical forces within $\sim 2\,{\rm kpc}$ of the Sun, highlighting the rotation curve and vertical force profile in the Solar Neighbourhood. Finally, we show residuals for star counts in the $R-z$ and $z-v_z$ planes as well as maps of the mean radial and azimuthal velocities in the $z-v_z$ plane. Using our model for the potential, we also examine the star count residuals in action-frequency-angle coordinates. The {\it Gaia} phase spirals, velocity arches, some of the known moving groups and bending modes appear as well-defined features in these maps.

description: The article treats the conservation and valorization work of the Memorial of Moses on Mount Nebo in Jordan, still being completed. Hereby is a synthesis of the research activities and of the archaeological excavations carried out, starting from the ‘30s of the last century, through the realization of the first shelter of the Basilica in the ‘60s, until the early 2000s, when due to the urgent conservation needs was proposed a project for a new shelter and for a touristic visit system of the shrine. The new project, due to the dead of its promoter, to the problems of the site and to the political and social complexity of the region, suffered various interruptions. Now the project is almost completed and soon it will be possible to visit again this important archaeological site.

description: Motivated by Polychronakos' discovery that solitons exist in the hydrodynamic equations of continuum version of the Calogero model, we seek solitons in the classical dynamics of a continuum version of the Haldane-Shastry spin chain. We have obtained analytic multi-lump solitary wave solutions for our spin-field equation, and these solutions possess interesting topological features. We have performed numerical collision experiments showing that these solitary waves survive collisions, and thus suggest the existence of true multi-soliton solutions.

description: The Medicean villas have been designated as UNESCO World Heritage Sites. The gardens, the statues, the artificial caves, the historic landscape surrounding the villas, water resources, together with the architecture of the water, represent monumental and artistic values. This note describes the importance of archaeological and cultural heritage of the system of aqueducts of the historical villas of Petraia and Castle, at the base of the slopes of Monte Morello, on the outskirts of Florence. Some manufacts of the ancient acqueducts, their state of degradation, misuse of water supplies, are analyzed. In particular, in the general plans of development of these monumental sites, proposals for restoration and valorization of systems for the collection and distribution of water, to support reuse in the garden villas fountains, caves, suggestive games of water are analysed. The increasing of the hydrogeological resource, the setting-up of cultural itinerary of the acqueduct are important aspects of the future designs.

description: ObjectiveThe HIV care continuum among female sex workers (FSW), a key population, has not been well characterized, especially within the generalized epidemics of sub-Saharan Africa. This was the first study to characterize the HIV care continuum among FSW in Lilongwe, Malawi.MethodsFrom July through September 2014, we used venue-based sampling to enroll 200 adult FSW in Lilongwe, Malawi into a cross-sectional evaluation assessing HIV care continuum outcomes. Seropositive FSW, identified using HIV rapid testing, received rapid CD4 counts in addition to viral loads using dried blood spots. We calculated proportions of HIV-infected FSW who had history of care, were on ART, and had suppressed viral load and we used Poisson regression to estimate the associations of demographic characteristics and transmission risk behaviors with each outcome.ResultsHIV seroprevalence was 69% (n = 138). Among all FSW the median age was 24 years (IQR: 22–28). Among the 20% who were newly diagnosed and reported previously testing negative, the median time since last HIV test was 11 months (interquartile range: 3–17). The majority (69%) of HIV-infected FSW had a history of HIV care, 52% reported current ART use, and 45% were virally suppressed. Of the FSW who reported current ART use, 86% were virally suppressed. Transmission risk behaviors were not associated with continuum outcomes.ConclusionsFSW in Lilongwe were predominately young and have a high HIV prevalence. Only half of HIV-infected FSW reported current ART use, but the majority of those on ART were virally suppressed. To reduce ongoing transmission and improve health outcomes, increased HIV testing, care engagement, and ART coverage is urgently needed among FSW. Universal testing and treatment strategies for all FSW in Malawi must be strongly considered.

description: Plasmid purification is a basic tool of molecular biologists. Although the development of plasmid isolation kits utilizing silica spin columns reduced the time and labor spent on plasmid purification, achieving large plasmid DNA yields still requires significant time and effort. Here we introduce the Miraprep, a rapid protocol that allows isolation of plasmid DNA using commercial Miniprep kits, but with DNA yields comparable to commercial Maxiprep plasmid purifications. Combining ethanol precipitation with spin column purification, we created a DNA isolation protocol that yields highly concentrated plasmid DNA samples in less than 30 minutes. We show that Miraprep isolated plasmids are as stable as plasmids isolated by standard procedures, can be used for standard molecular biology procedures including DNA sequencing, and can be efficiently transfected into mammalian cells. This new plasmid DNA isolation protocol will significantly reduce time and labor without increasing costs.

description: The Saadian sugar refinery of Chichaoua (XVI century), located southwest of Marrakech, is a large rammed earth building of relevant architectonic value, abandoned with the fall of Saadian dynasty. A structural study was undertaken to characterize the materials, to understand the construction techniques and to identify the structural criticities and the surface decay. In particular, carrying out physical and mineralogical analysis on earth samples, the use of two types of material was found, a first one with only soil earth and a second one with added lime. Mechanical tests, carried out by sclerometer and in laboratory, highlighted that the lime added earth exhibits great strength, exceeding the values known for that kind of building material. This conclusion throw light on the sophisticated building culture of the Saadian period in Morocco, as the El Bedi palace in Marrakech testifies too. The study of crack patterns shows the most common mechanisms of damage and consequently appropriate consolidation strategies.
