description: The coupling between the electrical transport properties of La2/3Sr1/3MnO3 (LSMO) thin films and structural phase transitions of SrTiO3 (STO) substrates at Ts = 105 K has been investigated. We found that the electrical resistivity of LSMO films exhibit a cusp at Ts, which is greatly amplified by tuning films to the verge of metallic and insulating phases, i.e., to the boundary of two delicate competing electronic states. Our results demonstrate that small amounts of strain can tip the subtle balance of competing interactions and tune the electronic properties in correlated electron materials.

description: Materials composed of two dimensional layers bonded to one another through weak van der Waals interactions often exhibit strongly anisotropic behaviors and can be cleaved into very thin specimens and sometimes into monolayer crystals. Interest in such materials is driven by the study of low dimensional physics and the design of functional heterostructures. Binary compounds with the compositions MX2 and MX3 where M is a metal cation and X is a halogen anion often form such structures. Magnetism can be incorporated by choosing a transition metal with a partially filled d-shell for M, enabling ferroic responses for enhanced functionality. Here a brief overview of binary transition metal dihalides and trihalides is given, summarizing their crystallographic properties and long-range-ordered magnetic structures, focusing on those materials with layered crystal structures and partially filled d-shells required for combining low dimensionality and cleavability with magnetism.

description: Localized-surface plasmon resonance is of importance in both fundamental and applied physics for the subwavelength confinement of optical field, but realization of quantum coherent processes is confronted with challenges due to strong dissipation. Here we propose to engineer the electromagnetic environment of metallic nanoparticles (MNPs) using optical microcavities. An analytical quantum model is built to describe the MNP-microcavity interaction, revealing the significantly enhanced dipolar radiation and consequentially reduced Ohmic dissipation of the plasmonic modes. As a result, when interacting with a quantum emitter, the microcavity-engineered MNP enhances the quantum yield over 40 folds and the radiative power over one order of magnitude. Moreover, the system can enter the strong coupling regime of cavity quantum electrodynamics, providing a promising platform for the study of plasmonic quantum electrodynamics, quantum information processing, precise sensing and spectroscopy.

description: Magnon-photon coupling in antiferromagnets has many attractive features that do not exist in ferro- or ferrimagnets. We show quantum-mechanically that, in the absence of an external field, one of the two degenerated spin wave bands couples with photons while the other does not. The photon mode anticrosses with the coupled spin waves when their frequencies are close to each other. Similar to its ferromagnetic counterpart, the magnon-photon coupling strength is proportional to the square root of number of spins $\sqrt{N}$ in antiferromagnets. An external field removes the spin wave degeneracy and both spin wave bands couple to the photons, resulting in two anticrossings between the magnons and photons. Two transmission peaks were observed near the anticrossing frequency. The maximum damping that allows clear discrimination of the two transmission peaks is proportional to $\sqrt{N}$ and it's well below the damping of antiferromagnetic insulators. Therefore the strong magnon-photon coupling can be realized in antiferromagnets and the coherent information transfer between the photons and magnons is possible.

Glutamatergic projections of the pedunculopontine nucleus to the substantia nigra
Creators: name: Diaz, Miguel Andres
Publisher: name: No Publisher Supplied
Year: 2022

description: The pedunculopontine nucleus (PPN) has traditionally been studied within the context of the midbrain locomotor region (MLR) (Shik et al., 1966; Grillner and Shik 1973; Mori et al., 1977 , Skinner and Garcia-Rill 1984), a descending motor control circuit. Yet, the dopaminergic nuclei of the substantia nigra and ventral tegmental area (VTA) receive the highest density of excitatory fibers from the PPN, most notably the substantia nigra pars compacta (SNc) (Dautan et al., 2021). While dopamine has implications in movement and exploratory behavior (Fink and Smith, 1980), the effect of PPN excitatory input on the SNc/VTA circuit remains poorly understood. The experiments herein address the organization of the glutamatergic (i.e. VGluT2+) PPN-to-substantia nigra efferent circuit in order to better understand the relationship between PPN and basal ganglia. Notably, excitatory circuits that originate in the PPN and terminate in specific basal ganglia nuclei appear to be segregated into separate circuits. Specifically, SNc- projecting glutamatergic PPN neurons do not project to the striatum except for rare exceptions. SNc-projecting PPN glutamatergic neurons collateralize to innervate specific nodes of the basal ganglia including the subthalamic nucleus (STN) and globus pallidus, but typically not the striatum. Anterograde transsynaptic labelling using an AAV1 construct (Zingg et al., 2017; Zingg et al., 2020) provides evidence that specific PPN neurons innervate segregated SNc/VTA subpopulations that project to unique subregions of the striatum, suggesting that the topography of the PPN may correspond to functional differences in basal ganglia control coincidentally observed along the dorsoventral axis of the striatum. Taken together, these findings suggest a model of PPN wherein heterogeneous subpopulations of VGluT2+ neurons form the basis for specific downstream effects on basal ganglia function via dopamine release and the feed- forward excitatory control of specific basal ganglia nodes.

description: The aims of the survey were:
 1. To carry out a systematic and comprehensive comparison of Family Expenditure (FES) and Family Resources Survey (FRS) micro-data as inputs into a tax-benefit microsimulation model.
 2. To draw general lessons from this exercise about the relative merits of the two datasets for descriptive purposes, and to establish the extent to which they can be considered as representative of the same population.
 3. To develop methods for the enhancement of FRS data with expenditure data from the FES, using statistical matching and other imputation techniques. The intention is to experiment and explore a range of techniques and assumptions with the aim of establishing the method that is best suited to the particular purpose: the calculation of the revenue and distributional effects of complex reforms to the tax benefit system.
 4. To draw general lessons from this exercise about the prospects and limitations of inter-dataset enhancements.
 5. To communicate the assumptions and conclusions of the study in a manner that is transparent and of widespread use. One part of this process will be to provide copies of the synthetic database to interested users, accompanied by detailed documentation (subject to permission from the data providers).
Inward Investment and UK Economic Performance, 1983-1992

description: The objective of this research was to undertake a quantitative analysis of the impact of inward investment on domestically-owned firms in the UK manufacturing sector in order to assess the hypothesis put forward in the Competitiveness White Paper that foreign firms have helped to raise the rate of labour productivity growth in the UK by transferring innovative production and managerial techniques. In particular the project wished to investigate:
 whether the presence of foreign-owned firms raises the rate of technical progress in domestic firms within the industry in which inward investment takes place.
 whether foreign investments in some industries also improve the performance of domestic firms in other manufacturing industries.
 whether there are significant differences in the demand for labour by domestic and foreign-owned firms.
 whether any conclusions are sensitive to different measures of the scale of UK operations by foreign-owned firms.
 whether there are significant differences in the 'spillover' effects of inward investments according to the nationality of the investor.
 whether any estimated effects from inward investment remain robust when other potential determinants of technical progress, such as imports and domestic R&D expenditures, are also included in the analysis.
 It has been confirmed that foreign-owned firms have a significant positive effect on the level of technical efficiency in domestic firms using an industry-level panel data set for the labour demand of domestic firms. This means that find ings in existing studies of a similar relationship for the aggregate manufacturing sector reflect genuine spillovers from foreign to domestic firms, rather than just a 'batting average' effect from a rising share of more productive fo reign firms.
 Evidence has been found of significant intra-industry and inter-industry spillovers from foreign firms. This means that inward investment policies designed to improve the general attractiveness of the UK as a business location through investment promotion, and improve the dissemination of new business practices across a wide range of industries, are likely to be of at least as much benefit as policies aimed at offering investment incentives in selected industries.
 Evidence has been found that the inward investment continues to have a significant positive effect on technical progress even when other factors such as imports and domestic R&D expenditures are allowed for. This provides robust evidence that inward investment is an important endogenous influence on the long-term prospects for economic growth in the UK. Inward investment appears to be a much more important source of technical progress than foreign trade.

description: To realize one desired nonadiabatic holonomic gate, various equivalent evolution paths can be chosen. However, in the presence of errors, these paths become inequivalent. In this paper, we investigate the difference of these evolution paths in the presence of systematic Rabi frequency errors and aim to find paths with optimal robustness to realize one-qubit nonadiabatic holonomic gates. We focus on three types of evolution paths in the $Λ$ system: paths belonging to the original two-loop scheme [New J. Phys. {\bf 14}, 103035 (2012)], the single-loop multiple-pulse scheme [Phys. Rev. A {\bf 94}, 052310 (2016)], and the off-resonant single-shot scheme [Phys. Rev. A {\bf 92}, 052302 (2015); Phys. Lett. A {\bf 380}, 65 (2016)]. Whereas both the single-loop multiple-pulse and single-shot schemes aim to improve the robustness of the original two-loop scheme by shortening the exposure to decoherence, we here find that the two-loop scheme is more robust to systematic errors in the Rabi frequencies. More importantly, we derive conditions under which the resilience to this kind of error can be optimized, thereby strengthening the robustness of nonadiabatic holonomic gates.

description: We study analytically the one-loop contribution to the Chiral Magnetic Effect(CME) using lattice regularization with a Wilson fermion field. In the continuum limit, we find that the chiral magnetic current vanishes at nonzero temperature but emerges at zero temperature consistent with that found by Pauli-Villas regularization. For finite lattice size, however, the chiral magnetic current is nonvanishing at nonzero temperature. But the numerical vaule of the coefficient of CME current is very small compared with that extracted from the full QCD simulation for the same lattice parameters. The possibility of higher order corrections from QCD dynamics is also assessed.

description: The advancement of our understanding of MHD turbulence opens ways to develop new techniques to probe magnetic fields. In MHD turbulence, the velocity gradients are expected to be perpendicular to magnetic fields and this fact was used by Gonsalvez-Casanova & Lazarian to introduce a new technique to trace magnetic fields using velocity centroid gradients. The latter can be obtained from spectroscopic observations. We apply the technique to GALFA HI survey data and compare the directions of magnetic fields obtained with our technique with the direction of magnetic fields obtained using PLANCK polarization. We find excellent correspondence between the two ways of magnetic field tracing, which is obvious via visual comparison and through measuring of the statistics of magnetic field fluctuations obtained with the polarization data and our technique. This suggests that the velocity centroid gradients can provide a reliable way of measuring of the foreground magnetic field fluctuations and thus provide a new way of separating foreground and CMB polarization signals.

description: CO--0.40--0.22 is a peculiar molecular cloud that is compact and has an extraordinary broad velocity width. It is found in the central molecular zone of our Galaxy. In this direction, there is another cloud with an H$_2$O maser spot at a lower velocity. Collision with this low-velocity cloud could be responsible for the broad velocity width of CO--0.40--0.22. We performed phase-referencing VLBI astrometry with VERA and detected the annual parallax of the H$_2$O maser spot in the low-velocity cloud to be $0.33 \pm 0.14$ mas, which corresponds to a distance of $3.07^{+2.22}_{-0.91}$ kpc from the Sun. This implies that the low-velocity cloud is located in the Galactic disk on the near side of the central molecular zone.

description: We numerically investigate the ratchet transport of mixtures of active and passive particles in a transversal asymmetric channel.A big passive particle is immersed in a 'sea' of active particles. Due to the chirality of active particles, the longitudinal directed transport is induced by the transversal asymmetry. For the active particles, the chirality completely determines the direction of the ratchet transport, the counterclockwise and clockwise particles move to the opposite directions and can be separated. However, for the passive particle, the transport behavior becomes complicated, the direction is determined by competitions among the chirality, the self-propulsion speed, and the packing fraction. Interestingly, within certain parameters, the passive particle moves to the left,while active particles move to the right. In addition, there exist optimal parameters(the chirality, the height of the barrier, the self-propulsion speed and the packing fraction) at which the rectified efficiency takes its maximal value. Our findings could be used for the experimental pursuit of the ratchet transport powered by chiral active particles.

We proposed zero-contention cache memory or policy between REE and TEE to prevent from TruSpy attacks in TrustZone. And we suggested that delay time of data path of REE is equal or similar to that of data path of TEE to prevent timing side-channel attacks. Also, we proposed security information flow control based on the Clark-Wilson model, and built the information flow control mechanism using Authentication Tokenization Program (ATP). Accordingly we can expect the improved integrity of the information content between REE and TEE on mobile devices.

description: We introduce a new dynamic data structure for maintaining the strongly connected components (SCCs) of a directed graph (digraph) under edge deletions, so as to answer a rich repertoire of connectivity queries. Our main technical contribution is a decremental data structure that supports sensitivity queries of the form "are $ u $ and $ v $ strongly connected in the graph $ G \setminus w $?", for any triple of vertices $ u, v, w $, while $ G $ undergoes deletions of edges. Our data structure processes a sequence of edge deletions in a digraph with $n$ vertices in $O(m n \log{n})$ total time and $O(n^2 \log{n})$ space, where $m$ is the number of edges before any deletion, and answers the above queries in constant time. We can leverage our data structure to obtain decremental data structures for many more types of queries within the same time and space complexity. For instance for edge-related queries, such as testing whether two query vertices $u$ and $v$ are strongly connected in $G \setminus e$, for some query edge $e$. As another important application of our decremental data structure, we provide the first nontrivial algorithm for maintaining the dominator tree of a flow graph under edge deletions. We present an algorithm that processes a sequence of edge deletions in a flow graph in $O(m n \log{n})$ total time and $O(n^2 \log{n})$ space. For reducible flow graphs we provide an $O(mn)$-time and $O(m + n)$-space algorithm. We give a conditional lower bound that provides evidence that these running times may be tight up to subpolynomial factors.

description: We address the problem of estimating image difficulty defined as the human response time for solving a visual search task. We collect human annotations of image difficulty for the PASCAL VOC 2012 data set through a crowd-sourcing platform. We then analyze what human interpretable image properties can have an impact on visual search difficulty, and how accurate are those properties for predicting difficulty. Next, we build a regression model based on deep features learned with state of the art convolutional neural networks and show better results for predicting the ground-truth visual search difficulty scores produced by human annotators. Our model is able to correctly rank about 75% image pairs according to their difficulty score. We also show that our difficulty predictor generalizes well to new classes not seen during training. Finally, we demonstrate that our predicted difficulty scores are useful for weakly supervised object localization (8% improvement) and semi-supervised object classification (1% improvement).

description: Next-generation supercomputers will feature more hierarchical and heterogeneous memory systems with different memory technologies working side-by-side. A critical question is whether at large scale existing HPC applications and emerging data-analytics workloads will have performance improvement or degradation on these systems. We propose a systematic and fair methodology to identify the trend of application performance on emerging hybrid-memory systems. We model the memory system of next-generation supercomputers as a combination of "fast" and "slow" memories. We then analyze performance and dynamic execution characteristics of a variety of workloads, from traditional scientific applications to emerging data analytics to compare traditional and hybrid-memory systems. Our results show that data analytics applications can clearly benefit from the new system design, especially at large scale. Moreover, hybrid-memory systems do not penalize traditional scientific applications, which may also show performance improvement.

description: We review charge transport across molecular monolayers, which is central to molecular electronics (MoE) using large-area junctions (NmJ). We strive to provide a wide conceptual overview of three main sub-topics. First, a broad introduction places NmJ in perspective to related fields of research, and to single molecule junctions (1mJ), in addition to a brief historical account. As charge transport presents an ultra sensitive probe for the electronic perfection of interfaces, in the second part ways to form both the monolayer and the contacts are described to construct reliable, defect-free interfaces. The last part is dedicated to understanding and analyses of current-voltage (I-V) traces across molecular junctions. Notwithstanding the original motivation of MoE, I-V traces are often not very sensitive to molecular details and then provide a poor probe for chemical information. Instead we focus on how to analyse the net electrical performance of molecular junctions, from a functional device perspective. Finally, we shortly point to creation of a built-in electric field as a key to achieve functionality, including non-linear current-voltage characteristics that originate in the molecules or their contacts to the electrodes.

description: We study the behaviour of the most characteristic Raman contributions of highly oriented pyrolytic graphite at biaxial stresses up to 5 GPa. We use moissanite anvils to compress the samples, which allowed us to observe for the first time the evolution with stress of the disorder-induced D band along with all the overtones and combination bands in the Raman spectrum of graphite. Theoretical calculations at different pressures, performed within the density functional theory, are provided to confirm that the D band process involves iTO phonons along the K–C direction. A complete set of Grüneisen parameters is reported for all the features of the Raman spectrum of graphite; the analysis of the ratios of such parameters provides direct information on the intrinsic coupling and stress response of each phonon branch.

description: The synthesis of non-magnetic 2D dielectric cloaks as proper solutions of an inverse scattering problem is addressed in this paper. Adopting the relevant integral formulation governing the scattering phenomena, analytic and numerical approaches are exploited to provide new insights on how frequency and direction of arrival of the incoming wave may influence the cloaking mechanism in terms of permittivity distribution within the cover region. In quasi-static (subwavelength) regime a solution is analytically derived in terms of homogeneous artificial dielectric cover with $\varepsilon\varepsilon_0$ able to hide the object for a given number of directions of the incident field. Simulated results confirm the validity of both analytic and numerical methodologies and allow to estimate effective bandwidths both in terms of frequency range and direction of arrival of the impinging field.

description: Existing approaches to online convex optimization (OCO) make sequential one-slot-ahead decisions, which lead to (possibly adversarial) losses that drive subsequent decision iterates. Their performance is evaluated by the so-called regret that measures the difference of losses between the online solution and the best yet fixed overall solution in hindsight. The present paper deals with online convex optimization involving adversarial loss functions and adversarial constraints, where the constraints are revealed after making decisions, and can be tolerable to instantaneous violations but must be satisfied in the long term. Performance of an online algorithm in this setting is assessed by: i) the difference of its losses relative to the best dynamic solution with one-slot-ahead information of the loss function and the constraint (that is here termed dynamic regret); and, ii) the accumulated amount of constraint violations (that is here termed dynamic fit). In this context, a modified online saddle-point (MOSP) scheme is developed, and proved to simultaneously yield sub-linear dynamic regret and fit, provided that the accumulated variations of per-slot minimizers and constraints are sub-linearly growing with time. MOSP is also applied to the dynamic network resource allocation task, and it is compared with the well-known stochastic dual gradient method. Under various scenarios, numerical experiments demonstrate the performance gain of MOSP relative to the state-of-the-art.

description: We study the nuclear modifications of full jets and their structures in relativistic heavy-ion collisions including the effect of hydrodynamic medium response to jet quenching. To study the evolutions of the full jet shower and the traversed medium with energy and momentum exchanges between them, we formulate a coupled jet-fluid model consisting of a set of jet transport equations and relativistic hydrodynamics equations with source terms. In our model, the full jet shower interacts with the medium and gets modified via collisional and radiative processes during the propagation. Meanwhile, the energy and momentum are deposited from the jet shower to the medium and then evolve with the medium hydrodynamically. The full jet defined by a cone size in the final state includes the jet shower and the particles produced from jet-induced flow. We apply our model to calculate the full jet energy loss and the nuclear modifications of jet rate and shape in Pb+Pb collisions at $2.76{\rm A~TeV}$. It is found that the inclusion of jet-induced flow contribution leads to stronger jet-cone size dependence for jet energy loss and jet suppression. Jet-induced flow also has a significant contribution to jet shape function and dominates at large angles away from the jet axis.

description: The energy bandgap is an intrinsic character of semiconductors, which largely determines their properties. The ability to continuously and reversibly tune the bandgap of a single device during real time operation is of great importance not only to device physics but also to technological applications. Here we demonstrate a widely tunable bandgap of few-layer black phosphorus (BP) by the application of vertical electric field in dual-gated BP field-effect transistors. A total bandgap reduction of 124 meV is observed when the electrical displacement field is increased from 0.10V/nm to 0.83V/nm. Our results suggest appealing potential for few-layer BP as a tunable bandgap material in infrared optoelectronics, thermoelectric power generation and thermal imaging.

description: The present paper deals with an experimental feasibility study concerning the detection of long- range intermolecular interactions through molecular diffusion behavior in solution. This follows previous analyses, theoretical and numerical, where it was found that inter-biomolecular long-range force fields of electrodynamic origin could be detected through deviations from Brownian diffusion. The suggested experimental technique was Fluorescence Correlation Spectroscopy (FCS). By con- sidering two oppositely charged molecular species in watery solution, that is, Lysozyme protein and a fluorescent dye molecule (Alexa488), the diffusion coefficient of the dye has been measured by means of the FCS technique at different values of the concentration of Lysozyme molecules, that is, at different average distances between the oppositely charged molecules. For the model consid- ered long-range interactions are built-in as electrostatic forces, the action radius of which can be varied by changing the ionic strength of the solution. The experimental outcomes clearly prove the detectability of long-range intermolecular interactions by means of the FCS technique. Molecular Dynamics simulations provide a clear and unambiguous interpretation of the experimental results.

A Possible Mechanism for Driving Oscillations in Hot Giant Planets

description: The $κ$-mechanism has been successful in explaining the origin of observed oscillations of many types of "classical" pulsating variable stars. Here we examine quantitatively if that same process is prominent enough to excite the potential global oscillations within Jupiter, whose energy flux is powered by gravitational collapse rather than nuclear fusion. Additionally, we examine whether external radiative forcing, i.e. starlight, could be a driver for global oscillations in hot Jupiters orbiting various main-sequence stars at defined orbital semimajor axes. Using planetary models generated by the Modules for Experiments in Stellar Astrophysics (MESA) and nonadiabatic oscillation calculations, we confirm that Jovian oscillations cannot be driven via the $κ$-mechanism. However, we do show that in hot Jupiters oscillations can likely be excited via the suppression of radiative cooling due to external radiation given a large enough stellar flux and the absence of a significant oscillatory damping zone within the planet. This trend seems to not be dependent on the planetary mass. In future observations we can thus expect that such planets may be pulsating, thereby giving greater insight into the internal structure of these bodies.

Noncomutativity in near horizon symmetries in gravity

description: We have a new observation that near horizon symmetry generators, corresponding to diffeomorphisms which leave the horizon structure invariant, satisfy noncommutative Heisenberg algebra. The results are valid for any null surfaces (which has Rindler structure in the near null surface limit) and in any spacetime dimensions. Using Sugawara construction technique the central charge is identified. It is shown that the horizon entropy is consistent with the standard form of Cardy formula. Therefore we feel that the noncommutative algebra might leads to quantum mechanics of horizon and also can probe into the microscopic description of entropy.

description: For my dissertation, I conducted a survey of blow flies (Diptera: Calliphoridae) in Sicily, Italy and Ecuador across four different altitudinal levels (Sicily: 20m, 700m, 1153m, and 1552m; Ecuador: 561m, 1312m, 1948m, and 3336m). I determined the species richness, abundance and diversity of the blow fly communities in these two areas and across four elevations using four RESCUE!® POP! Fly Trap per baited with 100g of beef liver per trap. Twelve blow fly species were collected in Sicily while 17 species were collected in Ecuador. The main species collected in Sicily was Lucilia sericata (Meigen) (68.50%) while Consomyiops verena (Walker) was the main species collected (51.67% of total capture) in Ecuador. The total number of flies captured was highest at high elevations in Ecuador, while in Sicily it was highest at intermediate elevations. Blow fly activity was also assessed in lava fields and volcanic caves in Sicily during the winter months and showed that colonization occurred even in the caves in the absence of light and the presence of low temperatures (between 4°C and 6°C). Furthermore, I investigated the food preference of Calliphora vicina (Robineau-Desvoidy) (Diptera: Calliphoridae) adults among different food sources, noticing significant differences between males and females for certain trophic substrates. Finally, I conducted a geometric morphometric analysis of the right wing of C. vicina adults collected from different altitudinal levels and found significant differences across elevations, as well as between females and males.

description: Starting from the semi-analytic construction of a equation of state (EoS) which takes into account nuclear and quark matter at finite temperature, we study the possibility that proto-neutron stars, be proto-hybrid stars whose cores are composed of quark matter. We obtain the mass-radius relationship and discuss the latest constraints on masses and radii of neutron stars, considering the pulsars PSR J1614-2230 and PSR J0348 + 0432.

description: Sorting of microswimmers based on their mobility properties is of utmost importance for various branches of science and engineering. In this paper, we proposed a novel sorting method, where the mixed chiral particles can be separated by applying two opposite rotary obstacles. It is found that when the angular speed of the obstacles, the angular speed of active particles and the self-propulsion speed satisfy a certain relation, the mixed particles can be completely separated and the capture efficiency takes its maximal value. Our results may have application in capture or sorting of chiral active particles, or even measuring the chirality of active particles.
