description: We investigate the electron quantum path interference effects during high harmonic generation in atomic gas medium driven by ultrashort chirped laser pulses. To achieve that, we identify and vary the different experimentally relevant control parameters of such a driving laser pulse influencing the high harmonic spectra. Specifically, the impact of the pulse duration, peak intensity and instantaneous frequency is studied in a self-consistent manner based on Lewenstein formalism. Simulations involving macroscopic propagation effects are also considered. The study aims to reveal the microscopic background behind a variety of interference patterns capturing important information both about the fundamental laser field and the generation process itself. The results provide guidance towards experiments with chirp control as a tool to unravel, explain and utilize the rich and complex interplay between quantum path interferences including the tuning of the periodicity of the intensity dependent oscillation of the harmonic signal, and the curvature of spectrally resolved Maker fringes.

(Fig. 194)
A single female examined from Meghalaya, northeastern India (Fig. 194) appears to be different from its congeners. It is similar to S. melanopepla in having distinct microsculpture on interspaces between punctures on pronotum and elytra, but distinctly larger in size (length: 8.70 mm) with a differently shaped spermatheca. The shape of the spermatheca and the anteriorly sclerotized, funnel-shaped infundibulum are somewhat similar to those in S. obscura, but the latter does not have microsculpture on interspaces between punctures. It is not described as a new species in the absence of associated males.
Distribution. India (northeastern region).

description: Recent increases in the price of crude oil have led to a rise in the prominence of corn-based ethanol as an alternative source of energy. As a result linkages have been established between commodity and energy prices. The aim of this study is to determine if soybeans, corn, wheat, oil, and ethanol adjust their prices asymmetrically depending on whether their actual price is over- or under-predicted with respect to one another. This study’s goal of determining if asymmetric price relationships exist is accomplished by using monthly time series price data incorporated into a distributed lag error correction model distinguishing between positive and negative price difference and positive and negative values of the error correction term. The primary results of this study found that asymmetric price changes do occur in the commodity and energy markets. Interestingly, in all the asymmetric price adjustments that were found, with only one exception in the soybean-corn relationship, prices will adjust downward when the actual price of one variable is above its equilibrium price as determined by the price of another study variable and consequently would be expected to exhibit a downward adjustment in price in the following month.

Synonycha Chevrolat in Dejean, 1836: 460.
Type species: Coccinella grandis Thunberg, 1781, by monotypy.
Diagnosis. Size large (12–15 mm), form broadly rounded with explanate lateral margins of elytra. Antennal scape strongly broadened and obtusely produced anteriorly on the inner edge (at least two times broader than pedicel), terminal antennomere broad oval. Prothoracic hypomeron with anterior foveae. Anterior margin of mesoventrite medially deeply emarginate. Abdominal postcoxal line incomplete without an associated line. Tarsal claws double, swollen at base. Sperm duct below apex, inserted ventrally on bursa; and spermatheca strongly curved and c-shaped, with only ramus developed.
Distribution. Widely distributed in the Oriental region (India, Sri Lanka, Nepal, Myanmar, Vietnam, Laos), also found in parts of the Palaearctic (China, Japan).
Affinities. The Old World Megalocaria and Oriental Synonycha are the among the largest coccinellids in the world with body lengths of 10–18 mm, and species of both genera are typical aphid feeders with some exceptions like the African Megalocaria tetrasticta (Fairmaire) that feeds on eggs and nymphs of Plataspidae (Hemiptera) (Dejean et al. 2002). Tomaszewska et al. (2021) recovered Synonycha and Megalocaria as sister groups with strong support in terms of: terminal labial palpomere about as broad as penultimate one, mesoventrite anterior margin strongly emarginate, medially forming ‘V’ or ‘U’ shape, elytral lateral margins without visible bead and elytral epipleura with foveae for the apices of hind femora.

description: The vortex free energy is studied in the random vortex world-surface model of the infrared sector of SU(3) Yang-Mills theory. The free energy of a center vortex extending into two spatial directions, which is introduced into Yang-Mills configurations when acting with the 't Hooft loop operator, is verified to furnish an order parameter for the deconfinement phase transition. It is shown to exhibit a weak discontinuity at the critical temperature, corresponding to the weak first order character of the transition.

Hydrogen Atom in Relativistic Motion

description: The Lorentz contraction of bound states in field theory is often appealed to in qualitative descriptions of high energy particle collisions. Surprisingly, the contraction has not been demonstrated explicitly even in simple cases such as the hydrogen atom. It requires a calculation of wave functions evaluated at equal (ordinary) time for bound states in motion. Such wave functions are not obtained by kinematic boosts from the rest frame. Starting from the exact Bethe-Salpeter equation we derive the equal-time wave function of a fermion-antifermion bound state in QED, i.e., positronium or the hydrogen atom, in any frame to leading order in alpha. We show explicitly that the bound state energy transforms as the fourth component of a vector and that the wave function of the fermion-antifermion Fock state contracts as expected. Transverse photon exchange contributes at leading order to the binding energy of the bound state in motion. We study the general features of the corresponding fermion-antifermion-photon Fock states, and show that they do not transform by simply contracting. We verify that the wave function reduces to the light-front one in the infinite momentum frame.

description: We find an upper bound for the asymptotic dimension of a hyperbolic metric space with a set of geodesics satisfying a certain boundedness condition studied by Bowditch. The primary example is a collection of tight geodesics on the curve graph of a compact orientable surface. We use this to conclude that a curve graph has finite asymptotic dimension. It follows then that a curve graph has property $A_1$. We also compute the asymptotic dimension of mapping class groups of orientable surfaces with genus $\le 2$.

description: Using Monte-Carlo simulation, , we compare the most popular demand systems including the LES, AIDS, BTL, QES, QUAIDS and AIDADS, and find that different models actually have different advantages in estimating different elasticities. Specifically, QES, AIDS and AIDADS models are the best in income, own-price and cross-price elasticities, respectively. Overall, AIDADS model has the best performance. The results indicate that the rank three models are not necessary always better than the rank two models.

description: The Ensemble Kalman Filter (EnKF) is a popular sequential data assimilation method that has been increasingly used for parameter estimation and forecast prediction in epidemiological studies. The observation function plays a critical role in the EnKF framework, connecting the unknown system variables with the observed data. Key differences in observed data and modeling assumptions have led to the use of different observation functions in the epidemic modeling literature. In this work, we present a novel computational analysis demonstrating the effects of observation function selection when using the EnKF for state and parameter estimation in this setting. In examining the use of four epidemiologically-inspired observation functions of different forms in connection with the classic Susceptible-Infectious-Recovered (SIR) model, we show how incorrect observation modeling assumptions (i.e., fitting incidence data with a prevalence model, or neglecting under-reporting) can lead to inaccurate filtering estimates and forecast predictions. Results demonstrate the importance of choosing an observation function that well interprets the available data on the corresponding EnKF estimates in several filtering scenarios, including state estimation with known parameters, and combined state and parameter estimation with both constant and time-varying parameters. Numerical experiments further illustrate how modifying the observation noise covariance matrix in the filter can help to account for uncertainty in the observation function in certain cases.

description: We have calculated the optical spectra of Na$_{x}$CoO$_2$ for $x$=0.3, 0.5, and 0.7 within the LDA. We compare our results to available experimental data and show that the important features and trends are reproduced well, but there is a nearly uniform shift of peak positions and poor agreement in intensities. We show, through application of a simple model, that these differences can be attributed to overhybridization between Co and O orbitals and spin fluctuations which renormalize the bandwidth. Applying the LDA+U procedure shifts the optical peaks further from their experimental locations, indicating that this method of incorporating correlation effects is ill-suited for the case NaxCoO2.

description: Organic soymilk has been one of the fastest growing products in the organic food sector in recent years. Due to the shortage of domestically grown organic soybeans, outsourcing became a practice in the industry. It was estimated by some industry insiders that about 50% of organic soybeans consumed in the United States were imported from China (Cornucopia Institute, 2009). In 2009, the Organic Consumers Association called for a boycott of Silk products because it was reported that Silk, the dominant national brand in organic soymilk market, sourced organic soybeans from China and Brazil based on disputable standards. Under public pressure, Silk brand soymilk started to substitute U.S. grown non-genetically modified (GM) soybeans for imported organic soybeans. Correspondingly, the organic label on the product packaging was changed to ―all natural. The same behavior is also observed for soymilk by other brands. Another notable trend in the soymilk industry is that the dominance of national brands is challenged by a boom of private labeled soymilk products offered by stores across these marketing channels. The impacts of these changes in the organic soymilk industry could be significant for the distribution of economic benefits among the supply chain players. Our primary focus is to find whether US consumers distinguish organic processed foods by the origin of ingredients and brand types. We expect our findings to have wider implications to other processed foods. Preliminary results show consumers are willing to pay premiums for processed food like soymilk with organic and non-GM ingredients. The premium for organic soybeans is significantly higher than that for non-GM beans. The results also indicate that US consumers perceive the product with ingredients sourced from different origins distinctively, with a strong preference for organic soymilk produced with domestically produced soybeans. In terms of brand preferences, respondents are willing to pay more for national brands relative to store brands. Responses suggest that taste is a major factor in differentiating brands of soymilk. The willingness to pay for attributes varied with income and demographic characteristics of the households. Female and higher income groups appear more willing to pay for soymilk with organic ingredients. Older people are less likely to purchase organic soymilk. Moreover, older and female consumers perceive domestically produced ingredients better than imported ones. Yet, the more educated consumers are less willing to pay a premium for domestically produced organic ingredients.
Anti-GZK effect in Ultra High Energy Cosmic Rays diffusive propagation

description: We discuss the antiGZK effect in the diffusive propagation of ultra high energy protons in intergalactic magnetic fields, which consists in a jump-like increase of the maximum distance from which ultra high energy protons can reach an observer. The position of this jump, $E_j \approx 2\times 10^{18}$ eV, is determined exclusively by energy losses (transition from adiabatic to pair-production energy losses) and it is independent of the diffusion parameters. The diffuse spectrum presents a low-energy steepening approximately at this energy, which is very close to the position of the second knee observed in the cosmic ray spectrum. The dip, seen in the universal spectrum as a signature of the interaction with the cosmic microwave background radiation, is also present in the case of diffusive propagation in magnetic fields.

description: Measurements of The Hubble-Lemaitre constant from early- and local-universe observations show a significant discrepancy. In an attempt to understand the origin of this mismatch, independent techniques to measure H0 are required. One such technique, strong lensing time delays, is set to become a leading contender amongst the myriad methods due to forthcoming large strong lens samples. It is therefore critical to understand the systematic effects inherent in this method. In this paper, we quantify the influence of additional structures along the line-of-sight by adopting realistic light cones derived from the CosmoDC2 semi-analytical extra-galactic catalogue. Using multiple lens plane ray-tracing to create a set of simulated strong lensing systems, we have investigated the impact of line-of-sight structures on time-delay measurements and in turn, on the inferred value of H0. We have also tested the reliability of existing procedures for correcting for line-of-sight effects. We find that if the integrated contribution of the line-of-sight structures is close to a uniform mass sheet, the bias in H0 can be adequately corrected by including a constant external convergence $κ_{ext}$ in the lens model. However, for realistic line-of-sight structures comprising many galaxies at different redshifts, this simple correction overestimates the bias by an amount that depends linearly on the median external convergence. We, therefore, conclude that lens modelling must incorporate multiple lens planes to account for line-of-sight structures for accurate and precise inference of H0.

description: L’articolo intende fornire le coordinate filosofiche per affrontare la danza contemporanea da un punto di vista epistemologico. In primo luogo si rintracciano le due principali epistemi corporee che hanno informato la danza nel corso del Novecento, laddove alla danza moderna appartiene un modo di vedere e descrivere il corpo tendenzialmente ontologizzante, mentre a quella contemporanea uno costruttivista. In un secondo momento si presentano le filosofie di tre autori della postmodernità che si sono pronunciati in maniera significativa sul corpo contribuendo a mutarne radicalmente lo statuto. Tali teorie radicali e innovative, provenienti dal post-strutturalismo e dal femminismo, avrebbero registrato notevoli ripercussioni anche sull’estetica coreografica del secondo Novecento e oltre.

Substratum roughness alters the growth, area, and focal adhesions of epithelial cells, and their proximity to titanium surfaces
Creators: name: Baharloo, Bahador
Publisher: name: University of British Columbia
Year: 2009

description: Epithelial (E) cells were cultured on smooth tissue culture plastic (TCP), TCP-Ti, polishedTi (P) and rough grit blastedTi (B), acid etchedTi (AE), and grit blasted & acid etchedTi (SLA) surfaces and their growth, area, adhesion, and membrane-Ti proximity assessed. Rough surfaces decreased the growth of E cells compared to smooth surfaces in cultures up to 28 days. In general rough surfaces decreased the spreading of E cells as assessed by their area with the most pronounced affect for the SLA surface. On the other hand, the strength of E cells adhesion as inferred by immunofluorescence staining of vinculin in focal adhesions indicated that E cells formed more and larger focal adhesions on the smooth P surface compared to the rougher AE surface. As this finding indicates a stronger adhesion to smooth surfaces, it is likely that E cells on rough surfaces are more susceptible to mechanical removal. An immunogold labeling method was developed to visualize focal adhesions using back-scattered electron imaging with a scanning electron microscope (SEM). On rough surfaces focal adhesions were primarily localized on to the ridges rather than the valleys and the cells tended to bridge over the valleys. Transmission electron microscopy (TEM) measurements of membrane proximity to the Ti surface indicated that average distance of cell to the Ti increased as the Ti surface roughness increased. The size and shape of surface features are important determinants of epithelial adhesive behavior and epithelial coverage of rough surfaces would be difficult to attain if such surfaces become exposed.

description: There is a small number of known pulsating stars with transiting exoplanets. The analysis of such systems is challenging because the pulsation distorts the transits and therefore, the proper subtraction of the pulsation pattern is essential in order to model the transit light curves correctly. In addition, in close systems, the tidal forces of the companion may influence the oscillations. We performed photometric analysis of such systems using TESS space telescope data. We modeled the transit light curves and determined the basic parameters of the systems. We also found evidence of tidally perturbed stellar oscillations related to the substellar companions.

description: The association between prices and yields are of paramount importance to the crop insurance programs. Proper estimation of the association is highly desirable. Copulas are one such method to measure the dependence structure. Five single parametric copulas, a non- parametric copula and their fifteen different combinations taking a mixture of two different copulas at a time have been used in the crop insurance rating analysis. Using data of corn from 1973-2009 for 602 counties in the Mid-West area two different efficient methods have been proposed to generate the optimal mixtures using the cross validation approach. A resampling technique is used to check for the significance of the expected indemnities.

description: This study develops an analytical framework to examine the impact of generic advertising on brand advertising with alternative assumptions on demand changes (shift-up and rotation), product differentiation, market concentration, and relationship between commodity and brand advertising programs. The newly developed model allows one to determine the relationship between generic and brand advertising, which has not been clearly shown in previous studies. Analytical results show that when generic advertising leads to an inelastic demand, generic advertising would help brand advertising and could decrease the optimal brand advertising expenditures. However, when generic advertising leads to an elastic demand, it would negatively affect the profitability of brand advertising.

description: The novel coronavirus SARS-CoV-2 and resulting COVID-19 disease have had an unprecedented spread and continue to cause an increasing number of fatalities worldwide. While vaccines are still under development, social distancing, extensive testing, and quarantining of confirmed infected subjects remain the most effective measures to contain the pandemic. These measures carry a significant socioeconomic cost. In this work, we introduce a novel optimization-based decision-making framework for managing the COVID-19 outbreak in the US. This includes modeling the dynamics of affected populations, estimating the model parameters and hidden states from data, and an optimal control strategy for sequencing social distancing and testing events such that the number of infections is minimized. The analysis of our extensive computational efforts reveals that social distancing and quarantining are most effective when implemented early, with quarantining of confirmed infected subjects having a much higher impact. Further, we find that "on-off" policies alternating between strict social distancing and relaxing such restrictions can be effective at "flattening" the curve while likely minimizing social and economic cost.

description: We find a unitary operator which asymptotically diagonalizes the Tomonaga-Luttinger hamiltonian of one-dimensional spinless electrons. The operator performs a Bogoliubov rotation in the space of electron-hole pairs. If bare interaction of the physical electrons is sufficiently small this transformation maps the original Tomonaga-Luttinger system on a system of free fermionic quasiparticles. Our representation is useful when the electron dispersion deviates from linear form. For such situation we obtain non-perturbative results for the electron gas free energy and the density-density propagator.

description: Interest in promoting Pollution Prevention (P2) has been increasing since 1991, following the passage of the Pollution Prevention Act (PPA) of 1990. As part of the PPA, facilities that are subject to the Toxics Releases Inventory (TRI) are required to disclose the number of incremental P2 activities for each listed chemicals from 1991 onward. Though the disclosure is required by the PPA, the adoption of P2 remains a voluntary initiative by firms. To promote P2 ethic among firms, the U.S.EPA has established several voluntary programs and P2 information clearinghouse. P2 technologies were more likely to be facility- and operation- specific and involved considerable information costs and uncertainty. Firms might learn about P2 technologies from their peers through information spillovers. Furthermore, the adoption of P2 technologies might have been motivated in part by regulatory pressures and in part by voluntary commitments. To investigate the role of information spillover, regulatory pressure and voluntary commitment in motivating the adoption of P2 technologies, we focus on the first voluntary program initiated by the U.S. EPA, the 33/50 program. The objective of the program was to reduce the releases of 17 chemicals by 33% by 1992 and by 50% by 1995. It also sought to promote P2 as the preferred method to achieve the reduction. We conduct the empirical analysis on 6974 facilities that were eligible for the 33/50 program from 1991 to 1995. We estimate the number of P2 technologies adopted for 33/50 chemicals and other TRI chemicals at the facility level with respect to program participation, compliance costs to regulations, prior P2 experience by the neighbors on the respective chemicals, and the program participation ratio in the neighborhood. We address the endogeneity of program participation with instrumental variables, and control for location and industry fixed effects. We find that facilities were more likely to learn about adoption of P2 technologies from their industry peers. The direct impact of program participation was only evident for 33/50 chemicals, and the presence of program participants did not significantly motivate P2 adoption in the neighborhood.
Dances of Death: From Trans-genre to Media Phenomenon

description: The article aim to give an account of the interest aroused by the Dances of Death in the framework of semiotic studies with a focus on the social life of the discursive genres and on that of the mediatization of “long journey”, that is to say that we consider this phenomenon as constituting the human being as a biological species. Therefore we will address the prospective path that explores the phenomenon and survival of the Dances since their consolidation in the Middle Ages, as a transgender, and then, considering their re-emergence as an object of study in the present, we will focus the analysis on cases in which this genre is called through two modes of expression typical of contemporary art: cinema and video dance.

description: We developed a new joint probabilistic segmentation and image distribution matching generative adversarial network (PSIGAN) for unsupervised domain adaptation (UDA) and multi-organ segmentation from magnetic resonance (MRI) images. Our UDA approach models the co-dependency between images and their segmentation as a joint probability distribution using a new structure discriminator. The structure discriminator computes structure of interest focused adversarial loss by combining the generated pseudo MRI with probabilistic segmentations produced by a simultaneously trained segmentation sub-network. The segmentation sub-network is trained using the pseudo MRI produced by the generator sub-network. This leads to a cyclical optimization of both the generator and segmentation sub-networks that are jointly trained as part of an end-to-end network. Extensive experiments and comparisons against multiple state-of-the-art methods were done on four different MRI sequences totalling 257 scans for generating multi-organ and tumor segmentation. The experiments included, (a) 20 T1-weighted (T1w) in-phase mdixon and (b) 20 T2-weighted (T2w) abdominal MRI for segmenting liver, spleen, left and right kidneys, (c) 162 T2-weighted fat suppressed head and neck MRI (T2wFS) for parotid gland segmentation, and (d) 75 T2w MRI for lung tumor segmentation. Our method achieved an overall average DSC of 0.87 on T1w and 0.90 on T2w for the abdominal organs, 0.82 on T2wFS for the parotid glands, and 0.77 on T2w MRI for lung tumors.

description: The investigation of the temperature dependences of microwave surface impedance and complex conductivity of V3Si single crystals with different stoichiometry allowed to observe a number of peculiarities which are in remarkable contradiction with single-gap Bardeen-Cooper-Schrieffer theory. At the same time, they can be well described by two-band model of superconductivity, thus strongly evidencing the existence of two distinct energy gaps with zero-temperature values Delta1~1.8Tc and Delta2~0.95Tc in V3Si.

description: Motor complications in response to levodopa therapy are major problems in the treatment of Parkinson's disease (PD). In this study we investigated the possible relationship between the level of dopamine transporter expressed on surviving striatal dopaminergic terminals and variations in extracellular dopamine levels in PD patients with stable response to levodopa and those with motor fluctuations. We assessed the changes of endogenous and exogenous dopamine levels over time in response to oral methylphenidate and levodopa respectively. 3D PET was performed with the D2 receptor antagonist [¹¹C]raclopride (RAG) at baseline, 1 and 4 hours following the administration of oral methylphenidate (0.8 mg/kg) or oral levodopa (250/25 mg) to two groups of PD patients consisting of fluctuators and stable responders to levodopa. In parallel, we measured the ratio of dopamine transporters to the number of dopaminergic terminals in the striatum. For this purpose we used [¹¹C]MP and [¹¹C]DTBZ PET scans to estimate the levels of dopamine transporter expression and the vesicular monoamine transporter 2 (VMAT2) respectively. At the dose used, oral methylphenidate produced no significant change in extracellular dopamine levels, as estimated by comparing changes in putaminal RAC binding at baseline and one and four hours following its administration. This could be the result of severe degeneration of dopaminergic terminals with subsequent reductions in the levels of endogenous dopamine and DAT. Although the putaminal RAC binding significantly changed after administration of levodopa, the regression of RAC binding potentials at the three times to log (MP/DTBZ) was not significant implying that the ratio of dopamine transporters to dopaminergic terminals did not affect exogenous dopamine release and clearance.

description: La screendance cinese si è trasformata, rispetto alla medesima disciplina artistica emersa in Occidente, attraverso cambiamenti nelle definizioni e nelle pratiche. In questo articolo verranno esaminati gli elementi storici più rilevanti per la formazione e lo sviluppo della screendance cinese contemporanea mediante tre fasi di sviluppo definite e analizzate dal 1905 agli anni Settanta, dall’ultimo periodo dell’Impero Manchu alla Repubblica di Cina, fino alla Repubblica Popolare Cinese. Attraverso la disamina di documenti e testimonianze verrà individuato quali cambiamenti di forma (xing) sono stati provocati dal mutare delle visioni (xiang) definite dalle e soggette alle strutture socio-culturali cinesi degli specifici periodi storici e dei valori estetici ed etici da esse promossi.

Choreography, virility and the nation: the case of Vassos Kanellos
Creators: name: Leon, Anna
Publisher: name: Danza e ricerca
Year: 2021

description: Drawing from published and unpublished texts, iconographic material and press sources, this article discusses the work of Vassos Kanellos, a Greek dance artist active since the early 20th century. Examining how Kanellos’ dance staged a hegemonic masculinity and interweaved it with equally hegemonic representations of "Greekness", the article complements scholarship on Greek modern dance’s embodiment of gendered and national narratives. By contextualising his practice in local and transnational frameworks, notably studying the role of his U.S.-American collaborator and spouse Tanagra Kanellos, it also contributes to an understanding of the inscription of Greek (dance) modernity within Western (dance) modernity, in which it is severely under-represented.
