description: We introduce Shannon's information entropy to characterize the avoided crossing appearing in the resonant Zener-like phenomenon in ultrasonic superlattices made of two different fluidlike meta- materials. We show that Shannon's entropy gives a correct physical insight of the localization effects taking place and manifest the informational exchange of the involved acoustic states in the narrow region of parameters where the avoided crossing occurs. Results for ultrasonic structures consisting of alternating layers of methyl-metacrylate and water cavities, in which the acoustic Zener effect were recently demonstrated, are also reported.

description: The problem of disk accretion onto the surface of a neutron star with a weak magnetic field at a luminosity exceeding several percent of Eddington is reduced to the problem of the braking of a hypersonic flow with a velocity that is 0.4-0.5 of the speed of light above the base of the spreading layer -- a dense atmosphere made up of previously fallen matter. We show that turbulent braking in the Prandtl-Karman model with universally accepted coefficients for terrestrial conditions and laboratory experiments and a ladder of interacting gravity waves in a stratified quasi-exponential atmosphere at standard Richardson numbers lead to a spin-up of the massive zone that extends to the ocean made up of a plasma with degenerate electrons. Turbulent braking in the ocean at the boundary with the outer solid crust reduces the rotation velocity to the solid-body rotation velocity of the star. This situation should lead to strong heating of deep atmospheric layers and to the switch-off of the explosive helium burning mechanism. Obviously, a more efficient mechanism for the dissipation of a fast azimuthal flow in the atmosphere should operate in X-ray bursters. We show that a giant solitary gravity wave in the atmosphere can lead to energy dissipation and to a sharp decrease in azimuthal velocity in fairly rarefied atmospheric layers above the zone of explosive helium burning nuclear reactions. We discuss the reasons why this wave, that has no direct analog in the Earth's atmosphere or ocean, appears and its stability. We pose the question as to whether neutron stars with massive atmospheres, spun up to high velocities by accreting matter from a disk, can exist among the observed Galactic X-ray sources.

description: In a study with 112 third- and fourth-grade children, we measured the relative effectiveness of discovery learning and direct instruction at two points in the learning process: (a) during the initial acquisition of the basic cognitive objective (a procedure for designing and interpreting simple, unconfounded experiments) and (b) during the subsequent transfer and application of this basic skill to more diffuse and authentic reasoning associated with the evaluation of science-fair posters. We found not only that many more children learned from direct instruction than from discovery learning, but also that when asked to make broader, richer scientific judgments, the many children who learned about experimental design from direct instruction performed as well as those few children who discovered the method on their own. These results challenge predictions derived from the presumed superiority of discovery approaches in teaching young children basic procedures for early scientific investigations.
Femtosecond pulse with THz repetition frequency based on strong coupling between quantum emitters and a plasmonic resonator

description: Nanoscale pulsed light is highly desirable in nano-integrated optics. In this letter, we obtained femtosecond pulses with THz repetition frequency via the strong coupling between quantum emitters (QEs) and plasmonic resonators. Our structure consists of a V-groove (VG) plasmonic resonator and a nanowire embedded with two-level QEs. The influences of the incident light intensity and QE number density on the transmission response for this hybrid system are investigated through semi-classical theory and simulation. It is found that the transmission response can be modulated to the pulse form. The reason is the strong coupling causes the output power of nanowire to behave as an oscillating form, the oscillating output power in turn causes the field amplitude in the resonator to oscillate over time. A feedback system is formed between the plasmonic resonator and the QEs in nanowire. This provides a new method for generating narrow pulsed lasers with ultrahigh repetition frequency in plasmonic systems using a continous wave input, which has potential applications in generating optical clock signals at the nanoscale.
Spontaneous breaking of conformal invariance, solitons and gravitational waves in theories of conformally invariant gravitation

description: We study conformal gravity as an alternative theory of gravitation. For conformal gravity to be phenomenologically viable requires that the conformal symmetry is not manifest at the energy scales of the other known physical forces. Hence we require a mechanism for the spontaneous breaking of conformal invariance. In this paper we study the possibility that conformal invariance is spontaneously broken due to interactions with conformally coupled matter fields. The vacuum of the theory admits conformally non-invariant solutions corresponding to maximally symmetric space-times and variants thereof. These are either de Sitter space-time or anti-de Sitter space-time in the full four space-time dimensions or in a lower dimensional sub-space. We consider in particular normalizable, linearized gravitational perturbations around the anti-de Sitter background. Exploiting the conformal flatness of this space-time, we show to second order, that these gravitational fluctuations, that are taken to be fourier decomposable, carry zero energy-momentum. This squares well with the theorem that asymptotically flat space-times conformal gravity contain zero energy and momentum \cite{bhs}. We also show the possibility of domain wall solitons interpolating between the ground states of spontaneously broken conformal symmetry that we have found. These solitons necessarily require the vanishing of the scalar field, repudiating the recent suggestion \cite{f} that the conformal symmetry could be quarantined to a sterile sector of the theory by choosing an appropriate field redefinition.

description: Mindfulness is associated with reduced negative affective states, increased positive affective states, and reduced clinical affective symptomatology (e.g., depression, anxiety) in previous studies. This chapter examines an emerging body of fMRI and EEG research exploring how mindfulness alters neurobiological emotion processing systems. We examine how dispositional (trait) mindfulness and how adopting a mindful attentional stance (after varying levels of mindfulness training) relate to changes in neural responses to affective stimuli. Evidence suggests mindfulness-related changes in a ventral affective processing network associated with core affect, a dorsal processing network associated with making attributions and appraisals of one’s affective experience, and regulatory networks involved in modulating affective processes. These neural effects may underlie the previously observed relationships between mindfulness and changes in reported emotion processing and reactivity. Findings are discussed in light of existing neurobiological models of emotion and we describe important questions for the field in the coming years.

description: Construction material management is an essential factor that adversely affecting the
 performance of construction projects. This study was conducted with an objective of
 identifying construction material management practice and its effect on project delivery
 for public building projects in Addis Ababa. Based on the responsibility of managing
 construction materials, contractors were targeted as a study population. The study has
 targeted 40 contractors that are involved in public building projects those are currently
 under construction and used census as a sampling method. Intended data was collected
 through structured questionnaire and 38 questionnaires were responded and analyzed
 through both descriptive and explanatory methods by using a statistical software called
 SPSS 23. The study has identified the contractors are using three types of material
 management process i.e. the material is supplied based on the schedule on Bill of
 material, use warehouse to store the materials and search supplier for the materials
 when demanded. Among the three process types, type 1 is better in making the
 companies better performers in cost. In most of the projects multiple supplier is used
 for single material. Problems in material identification, planning, vendor selection,
 procurement and construction phase are root causes for ineffective material
 management. Construction project material management process type significantly
 affects the existence of cost overrun on the projects but does not affect the level of cost
 overrun. On the other hand, Construction material management process types do not
 affect the project time. Problems of material identification, planning, vendor selection,
 procurement and construction phase highly affect the cost overrun and time delay of
 the projects but effect of the vendor selection problems is lowest when compared to
 other problem categories. Majority of Contractors in public building projects in Addis
 Ababa are not using software to manage construction materials. To support
 construction material management, this study has developed pertinent software. The
 contractors are recommended to improve their construction material management
 practices and solve their material management problems by using the software.

Moreover, the currents of these carriers are unified under a global flavored SO(3) symmetry, which is dual to the bulk SO(3) gauge symmetry. We study the phase diagram of our model, and find it qualitatively agrees with the one for the realistic 2-band superconductor, such as $MgB_2$. We also identify the bulk field dual to the electromagnetic $U(1)_{EM}$ current, which should be invariant under the global flavored SO(3) rotation. We then evaluate the corresponding holographic conductivity and find the expected mean field like behaviors.

description: The contribution of line-of-sight peculiar velocities to the observed redshift of objects breaks the translational symmetry of the underlying theory, modifying the predicted 2-point functions. These `wide angle effects' have mostly been studied using linear perturbation theory in the context of the multipoles of the correlation function and power spectrum. In this work we present the first calculation of wide angle terms in the Zeldovich approximation, which is known to be more accurate than linear theory on scales probed by the next generation of galaxy surveys. We present the exact result for dark matter and perturbatively biased tracers as well as the small angle expansion of the configuration- and Fourier-space two-point functions and the connection to the multi-frequency angular power spectrum. We compare different definitions of the line-of-sight direction and discuss how to translate between them. We show that wide angle terms can reach tens of percent of the total signal in a measurement at low redshift in some approximations, and that a generic feature of wide angle effects is to slightly shift the Baryon Acoustic Oscillation scale.

description: We have studied the topology of the energy landscape of a spin-glass model and the effect of frustration on it by looking at the connectivity and disconnectivity graphs of the inherent structure. The connectivity network shows the adjacency of energy minima whereas the disconnectivity network tells us about the heights of the energy barriers. Both graphs are constructed by the exact enumeration of a two-dimensional square lattice of a frustrated spin glass with nearest-neighbor interactions up to the size of 27 spins. The enumeration of the energy-landscape minima as well as the analytical mean-field approximation show that these minima have a Gaussian distribution, and the connectivity graph has a log-Weibull degree distribution of shape $κ=8.22$ and scale $λ=4.84$. To study the effect of frustration on these results, we introduce an unfrustrated spin-glass model and demonstrate that the degree distribution of its connectivity graph shows a power-law behavior with the -3.46 exponent, which is similar to the behavior of proteins and Lennard-Jones clusters in its power-law form.

description: Spherically symmetric relativistic stars with the polytropic equation of state (EoS), which possess the local pressure anisotropy, are considered within the framework of general relativity. The generalized Lane-Emden equations are derived for the arbitrary anisotropy parameter $Δ=p_t-p_r$ ($p_t$ and $p_r$ being the transverse and radial pressure, respectively). They are then applied to some special ansatz for the anisotropy parameter in the form of the differential relation between the anisotropy parameter $Δ$ and the metric function $ν$. The analytical solutions of the obtained equations are found for incompressible fluid stars and then used for getting their mass-radius relation, gravitational and binding energy. Also, following the Chandrasekhar variational approach, the dynamical stability of incompressible anisotropic fluid stars with the polytropic EoS against radial oscillations is studied. It is shown that the local pressure anisotropy with $p_t>p_r$ can make the incompressible fluid stars unstable with respect to radial oscillations, in contrast to incompressible isotropic fluid stars with the polytropic EoS which are dynamically stable.

How geometrical shapes influence forces’ flow into elements is a basic point to better understand and design structures. The so-called “optimal” geometrical shape has a strong influence on structure definition, as the coupling between form and forces, usually called structural morphology, is a key point for success to solve challenging problems of large structures, both using conventional materials or innovative shapes and technologies. This School is focused on a practical approach to the coupling between form and forces in structural design, with emphasis on harmonizing the engineering and architectural vision of structural morphology.

description: The effects of intrinsic spin-orbit and Coulomb interactions on low-energy properties of finite width graphene armchair ribbons are studied by means of a Dirac Hamiltonian. It is shown that metallic states subsist in the presence of intrinsic spin-orbit interactions as spin-filtered edge states, in contrast with the insulating behavior predicted for graphene planes. A charge-gap opens due to Coulomb interactions in neutral ribbons, that vanishes as $Δ\sim 1/W $, with a gapless spin sector. Weak intrinsic spin-orbit interactions do not change the insulating behavior. Explicit expressions for the width-dependent gap and various correlation functions are presented.

description: As an emerging decentralized secure data management platform, blockchain has gained much popularity recently. To maintain a canonical state of blockchain data record, proof-of-work based consensus protocols provide the nodes, referred to as miners, in the network with incentives for confirming new block of transactions through a process of "block mining" by solving a cryptographic puzzle. Under the circumstance of limited local computing resources, e.g., mobile devices, it is natural for rational miners, i.e., consensus nodes, to offload computational tasks for proof of work to the cloud/fog computing servers. Therefore, we focus on the trading between the cloud/fog computing service provider and miners, and propose an auction-based market model for efficient computing resource allocation. In particular, we consider a proof-of-work based blockchain network. Due to the competition among miners in the blockchain network, the allocative externalities are particularly taken into account when designing the auction mechanisms. Specifically, we consider two bidding schemes: the constant-demand scheme where each miner bids for a fixed quantity of resources, and the multi-demand scheme where the miners can submit their preferable demands and bids. For the constant-demand bidding scheme, we propose an auction mechanism that achieves optimal social welfare. In the multi-demand bidding scheme, the social welfare maximization problem is NP-hard. Therefore, we design an approximate algorithm which guarantees the truthfulness, individual rationality and computational efficiency. Through extensive simulations, we show that our proposed auction mechanisms with the two bidding schemes can efficiently maximize the social welfare of the blockchain network and provide effective strategies for the cloud/fog computing service provider.

description: How does the brain manage to store and process multiple languages without encountering massive interference and transfer? Unless we believe that bilinguals live in two totally unconnected cognitive worlds, we would expect far more transfer than actually occurs. However, imaging and lesion studies have not provided consistent evidence for the strict neuronal separation predicted by the theory of modularity. We suggest that emergentist theory offers a promising alternative. It emphasizes the competitive interplay between multiple languages during childhood and by focusing on the dual action of competition and entrenchment, avoids the need to invoke a critical period to account for age of acquisition effects in second-language learning. This view instantiates the motto formulated by Elizabeth Bates that ‘modules are made, not born.’

description: Actions that produce sounds infuse our daily lives. Some of these sounds are a natural consequence of physical interactions (such as a clang resulting from dropping a pan), but others are artificially designed (such as a beep resulting from a keypress). Although the relationship between actions and sounds has previously been examined, the frame of reference of these associations is still unknown, despite it being a fundamental property of a psychological representation. For example, when an association is created between a keypress and a tone, it is unclear whether the frame of reference is egocentric (gesture-sound association) or exocentric (key-sound association). This question is especially important for artificially created associations, which occur in technology that pairs sounds with actions, such as gestural interfaces, virtual or augmented reality, and simple buttons that produce tones. The frame of reference could directly influence the learnability, the ease of use, the extent of immersion, and many other factors of the interaction. To explore whether action-sound associations are egocentric or exocentric, an experiment was implemented using a computer keyboard's number pad wherein moving a finger from one key to another produced a sound, thus creating an action-sound association. Half of the participants received egocentric instructions to move their finger with a particular gesture. The other half of the participants received exocentric instructions to move their finger to a particular number on the keypad. All participants were performing the same actions, and only the framing of the action varied between conditions by altering task instructions. Participants in the egocentric condition learned the gesture-sound association, as revealed by a priming paradigm. However, the exocentric condition showed no priming effects. This finding suggests that action-sound associations are egocentric in nature. A second part of the same session further confirmed the egocentric nature of these associations by showing no change in the priming effect after moving to a different starting location. Our findings are consistent with an egocentric representation of action-sound associations, which could have implications for applications that utilize these associations.

description: The toolbox for imaging molecules is well-equipped today. Some techniques visualize the geometrical structure, others the electron density or electron orbitals. Molecules are many-body systems for which the correlation between the constituents is decisive and the spatial and the momentum distribution of one electron depends on those of the other electrons and the nuclei. Such correlations have escaped direct observation by imaging techniques so far. Here, we implement an imaging scheme which visualizes correlations between electrons by coincident detection of the reaction fragments after high energy photofragmentation. With this technique, we examine the H2 two-electron wave function in which electron-electron correlation beyond the mean-field level is prominent. We visualize the dependence of the wave function on the internuclear distance. High energy photoelectrons are shown to be a powerful tool for molecular imaging. Our study paves the way for future time resolved correlation imaging at FELs and laser based X-ray sources.

description: This chapter describes a scenario where ridesharing is introduced in urban parking to relieve the pressure of finding a parking site in the city center. A significant amount of time is wasted in cruising for a parking lot according to both life experience and research findings. Although a few policies and strategies have been tested, the middle ground between individual flexibility and reduced travel demand is not yet well accommodated. Therefore, I report of a joint model of ridesharing and parking: people drive from their front doors to a satellite parking site to share rides, and travel to a similar destination in the city center so that parking demand is reduced.

description: Quantum oscillations have revealed the presence of a small pocket in the Fermi surface of the cuprate superconductor YBCO, whose nature and origin are the subject of much debate. Interpretations include electron and hole pockets; scenarios include Fermi-surface reconstruction by antiferromagnetism, d-density-wave order, and stripe order. Here we report quantum oscillations in the Seebeck and Nernst coefficients of YBCO and show, from the magnitude and sign of the Seebeck coefficient, that they come from an electron pocket. Using measurements of the Seebeck coefficient as a function of hole doping p, we show that the evolution of the Fermi surface in YBCO is the same as in Eu-LSCO, a cuprate where stripe order (a modulation of spin and charge densities) is well established. The electron pocket is most prominent where stripe order is strongest, at p = 1/8. This shows that Fermi-surface reconstruction is a generic mechanism of underdoped cuprates, intimately related to stripe order.

At one-loop order, the protection from ultraviolet sensitivity is due to an accidental non-compact symmetry of the Higgs potential that emerges in the infrared. Once the general features of the effective description are detailed, a completion that relies on a five dimensional supersymmetric framework is provided. Novel phenomenology is compared and contrasted with the Twin Higgs scenario.

description: K. J. Malmberg, J. Holden, and R. M. Shiffrin (2004) reported more false alarms for low- than high-frequency words when the foils were similar to the targets. According to the source of activation confusion (SAC) model of memory, that pattern is based on recollection of an underspecified episodic trace rather than the error-prone familiarity process. The authors tested the SAC account by varying whether participants were warned about the nature of similar foils and whether the recognition test required the discrimination. More false alarms for low-frequency similar items occurred only when participants were not warned at study about the subtle features to be discriminated later. The differential false-alarm rate by word frequency corresponded to the pattern of remember responses obtained when the test instructions did not ask for a subtle discrimination, supporting the SAC account that reversed false-alarm rates to similar foils are based on the recollection process.

description: Wayfinding has been widely studied in fields of locationbased service and geospatial cognition. It is currently unclear how wayfinding behaviour and spatial knowledge acquisition in immersive virtual reality (iVR) differ from those in real-world environments (REs). To investigate this question, we conducted the wayfinding experiment in RE with twenty-five participants and in iVR with forty participants. Participants’ eye movements, verbal reports and questionnaires were recorded. The results revealed that participants processed visual information more efficiently in RE but searched visual information more efficiently in iVR. For spatial learning, participants’ distance estimation was more accurate in iVR. This empirical study proves the ecological validity of iVR and encourages further studies to use VR techniques in wayfinding research.

description: Based on the analogy with non-minimal SU(2) symmetric Wu-Yang monopole with regular metric, the solution describing a non-minimal U(1) symmetric Dirac monopole is obtained. In order to take into account the curvature coupling of gravitational and electromagnetic fields, we reconstruct the effective metrics of two types: the so-called associated and optical metrics. The optical metrics display explicitly that the effect of birefringence induced by curvature takes place in the vicinity of the non-minimal Dirac monopole; these optical metrics are studied analytically and numerically.

production

description: The production of mushrooms in agroforestry systems (SAF) can be important and bring considerable economic benefits within the framework of sustainable use to the farmer. Saprophytic and ectomycorrhizal fungi are some of the most important fungi from an economic point of view. Natural saprophytic fungi (Macrolepiota procera, Agaricus spp., Etc.) may be important, for example, in the fallows of alley cropping or in certain silvopastoral systems (newly reforested meadows). However, these mushrooms do not have a great commercial importance. In the riparian buffer strips and hedges, mushrooms are produced in the spring (Morchella spp.) that could reach high prices. It is also possible to grow saprophytic mushrooms in the SAF, as a complementary production to several forest stands. For example, Pleurotus ostreatus in poplar stands or cultivated in different substrates (straw, chips ...) or Lentinus edodes in oak, chestnut or alder woodlands have a high productivity although the productions are seasonal, mainly limited to autumn and spring, unlike the cultivation in climatized areas.

description: Remarkable features have been predicted for the mechanical fluctuations at the bistability transition of a classical oscillator coupled capacitively to a quantum dot [Phys. Rev. Lett. 115, 206802 (2015)]. These results have been obtained in the regime $ω$0 $\ll$ kBT $\ll$ $Γ$, where $ω$0, T , and $Γ$ are the mechanical resonating frequency, the temperature, and the tunneling rate, respectively. A similar behavior could be expected in the quantum regime of $Γ$ $\ll$ kBT $\ll$ $ω$0. We thus calculate the energy and displacement fluctuation spectra and study their behavior as a function of the electro-mechanical coupling constant when the system enters the Frank-Condon regime. We find that, in analogy with the classical case, the energy fluctuation spectrum and the displacement spectrum widths show a maximum for values of the coupling constant at which a mechanical bistability establishes.

description: The current study investigated the sensitivity of face recognition to two changes of the stimulus, a rotation in depth and an inversion, by comparing the performance of two prosopagnosic patients, RN and CR, with non-neurological control subjects on a face-matching task. The control subjects showed an effect of depth rotation, with errors and reaction times increasing systematically with rotation angle, and the traditional inversion effect, with errors and reaction times increasing under inverted conditions. In contrast, RN showed no effect of rotation or inversion on his error data but did show a less sensitively graded effect of rotation and the traditional inversion effect on reaction times. CR did not show a graded effect of rotation on his errors or reaction times. Although CR showed the traditional inversion effect on his error data, he displayed an inversion superiority effect on his reaction time data, which supports the claim that the damaged holistic processing systems continue to dominate face processing in prosopagnosia even though they are malfunctioning. These results suggest that the damage that occurs to the ventral temporal cortex in prosopagnosia may have forced the patients to rely on sources of information that are not dependent on the view of the face and, moreover, cannot be adapted to deal with rotated faces under both upright and inverted conditions.

description: By generating the specifics of a network structure only when needed (on-the-fly), we derive a simple stochastic process that exactly models the time evolution of susceptible-infectious dynamics on finite-size networks. The small number of dynamical variables of this birth-death Markov process greatly simplifies analytical calculations. We show how a dual analytical description, treating large scale epidemics with a Gaussian approximations and small outbreaks with a branching process, provides an accurate approximation of the distribution even for rather small networks. The approach also offers important computational advantages and generalizes to a vast class of systems.

Prognostic performance of combined hematopoietic cell transplantation – comorbidity index, age and socioeconomic status in recipients of allogeneic hematopoietic cell transplants for patients with acute myeloid leukemia and myelodysplastic syndromes

description: Medical prognostication models based on both clinical and non-clinical characteristics are used to estimate the risk of outcomes in individuals undergoing hematopoietic cell transplant for acute myeloid leukemia and myelodysplastic syndrome. It is imperative that clinical decision makers have accurate tools for pre-transplant risk-benefit assessment that would allow for optimal stratification of patients to determine suitability of hematopoietic cell transplants (HCT), maximize the benefits of HCT to the patients and aid transplant centers optimize their resources. Using educational level, occupation status and income level as factors of socioeconomic status (SES) index, this study combines SES with hematopoietic cell transplantation comorbidity index (HCT-CI) and age before transplant to develop a new prognostic tool for overall survival and non-relapse mortality outcomes for patients with acute myeloid leukemia and myelodysplastic syndromes at Memorial Sloan Kettering Cancer Center (MSKCC). The predictive capabilities of the new HCT-CI/Age/SES for this single center cohort were compared to the HCT-CI and HCT-CI/Age. At 95% Confidence Interval, estimates of adjusted c-statistic for overall survival were 0.673 and 0.676 for HCT-CI and HCT-CI/Age, respectively, while it was 0.652 for HCT-CI/Age/SES index. The predictive capability of the latter suggests that the new tool can be a valuable prognostic assessment for overall survival outcome. Delineating the relative importance of SES and each of the individual factors, the SES index did not significantly predict either overall survival or non-relapse mortality at 2 years post HCT in this patient cohort. Advances in research, novel therapies, treatment expertise and optimal follow-up protocols at MSKCC may have contributed to ameliorate the impact of low SES; suggesting that with access to the same expert care, lower SES individuals can achieve similar treatment outcomes as those at higher SES levels.
