description: A relation between the number of bound collective excitations of an atomic Bose-Einstein condensate and the phase shift of elastically scattered atoms is derived. Within the Bogoliubov model of a weakly interacting Bose gas this relation is exact and generalises Levinson's theorem. Specific features of the Bogoliubov model such as complex-energy and continuum bound states are discussed and a numerical example is given.

description: We numerically investigate the odd parity states of the green exciton series in cuprous oxide. Taking into account the coupling to the yellow series and especially to the yellow continuum, the green excitons are quasi-bound resonances with a finite lifetime which cannot be described with Hermitian operators. To calculate their positions and linewidths, we use the method of complex-coordinate rotation, leading to a non-Hermitian complex eigenvalue problem. We find that the behavior of the dominant P states is very well approximated by a modified Rydberg formula using a negative quantum defect. The corresponding linewidths induced by the coupling to the yellow continuum decrease with the third power of the principal quantum number.

description: The present study examines the impact of the macroeconomic variables on the stock prices in India. To fulfil the objective of the study monthly data of inflation, short-term interest rate, long-term interest rate, index of industrial production, exchange rate, money supply, and the stock indices of CNX Nifty and BSE SENSEX were collected from March 2005 to April 2013. Heteroscedastic cointegration approach was employed using a Johansen test of cointegration, OLS and GARCH (1, 1) model to find out the long-term relationship between the selected macroeconomic variables and the stock prices. It is evident from the study that there exist the long-term heteroscedastic relationships between the stock prices and the macroeconomic variables chosen for the study. Further, it is also evident from the study that while INF, MSE and the IIP are positively related to the stock prices, the SIR, LIR and the EXR are negatively related to the stock prices.

description: The major scientific goals of DArk Matter Particle Explorer (DAMPE) are to study cosmic-ray electrons (including positrons) and gamma rays from 5 GeV to 10 TeV and nuclei from Z = 1 to 26 up to 100 TeV. The deposited energy measured by the Bismuth Germanate Oxide (BGO) calorimeter of DAMPE is affected by fluorescence attenuation in BGO crystals that are 600 mm long. In this work, an in-orbit attenuation calibration method is reported, and energy correction of the sensitive detector unit of the BGO calorimeter is also presented.

description: The vast extent and inaccessibility of boreal forest ecosystems are barriers to routine monitoring of forest structure and composition. In this research, we bridge the scale gap between intensive but sparse plot measurements and extensive remote sensing studies by collecting forest inventory variables at the plot scale using an unmanned aerial vehicle (UAV) and a structure from motion (SfM) approach. At 20 Forest Inventory and Analysis (FIA) subplots in interior Alaska, we acquired overlapping imagery and generated dense, 3D, RGB (red, green, blue) point clouds. We used these data to model forest type at the individual crown scale as well as subplot-scale tree density (TD), basal area (BA), and aboveground biomass (AGB). We achieved 85% cross-validation accuracy for five species at the crown level. Classification accuracy was maximized using three variables representing crown height, form, and color. Consistent with previous UAV-based studies, SfM point cloud data generated robust models of TD (r 2 = 0.91), BA (r 2 = 0.79), and AGB (r 2 = 0.92), using a mix of plot- and crown-scale information. Precise estimation of TD required either segment counts or species information to differentiate black spruce from mixed white spruce plots. The accuracy of species-specific estimates of TD, BA, and AGB at the plot scale was somewhat variable, ranging from accurate estimates of black spruce TD (+/−1%) and aspen BA (−2%) to misallocation of aspen AGB (+118%) and white spruce AGB (−50%). These results convey the potential utility of SfM data for forest type discrimination in FIA plots and the remaining challenges to develop classification approaches for species-specific estimates at the plot scale that are more robust to segmentation error.

description: Patch-clamp technique is the gold standard for cellular electrophysiological measurements, which is capable of measuring single ion transport events across the cell membrane. However, the measurement possesses significant complexity, and it requires a high level of expertise, while its experimental throughput is nevertheless considerably low. Here, we suggest and experimentally demonstrate a laser-assisted method for performing cellular electrophysiological measurements. Femtosecond laser pulses, coupled to an optical microscope, are used to form a sub-micrometer hole on a thin polymer membrane separating two electrodes, where a nearby cell is subsequently placed onto the hole by negative pressure. Afterwards, the cell is punctured using subsequent laser exposure, revealing the cell membrane over the hole for electrophysiological recording. This system could be used to increase the output amount of the electrophysiological measurements substantially.

description: We report our high-resolution (0.03 arcsec to 0.07 arcsec) ALMA imaging of the quadruply lensed radio-loud quasar MG\,J0414+0534 at redshift $z=2.639$ in the continuum and the broad CO(11-10) line at $\sim 340\,$GHz. With the help of strong lensing magnification and ALMA's high-resolution, we succeeded in resolving the jet/dust and CO gas in the quasar host galaxy both extending up to $\sim 1\,$kpc, with a resolution of $\sim 50\,$pc for the first time. Both the continuum emission and the CO(11-10) line have a similar bimodal structure aligned with the quasar jets ($\sim 200\,$pc) observed by Very Long Baseline Interferometry (VLBI) at $5\,$GHz and $8.4\,$GHz. The CO gas in the vicinity of both the eastern and western jet components at the location of $\sim 80\,$pc from the quasar core are moving at high velocities up to $\pm 600\,$$\textrm{km}\,\textrm{s}^{-1}$ relative to the core. The observed features show clear evidence of strong interaction between the jets and interstellar medium (ISM). High temperature and high density environments in the ISM of the quasar host galaxy, as suggested from CO line ratios, also support this result. The small scale of the jets, the jet-ISM interaction, and the continuum spectral energy distribution of this source indicate that we are watching the infancy stage of quasar radio activity.

Fishing downstream revisited : A multi-country analysis of anti-dumping patterns

Year: 2023

description: A long-held view in international trade policy analysis is that import protection flows downstream. This paper updates the descriptive analysis of Feinberg and Kaplan (1993), looking at trends in upstream and downstream antidumping and countervailing-duty cases since the US Trade Agreements Act of 1979. It covers the period from 1980 to 2015 for the five leading users of temporary trade barriers (TTBs): Argentina, Brazil, the European Union, India, and the United States. We examine evidence for two broad sectors which have dominated the use of TTBs: metals and chemicals. Both via descriptive trend analysis and simple statistical estimation, we find suggestive evidence in support of cascading trade protection, though more so for the developing countries studied.
Predicting the Popularity of Micro-videos with Multimodal Variational Encoder-Decoder Framework

description: As an emerging type of user-generated content, micro-video drastically enriches people's entertainment experiences and social interactions. However, the popularity pattern of an individual micro-video still remains elusive among the researchers. One of the major challenges is that the potential popularity of a micro-video tends to fluctuate under the impact of various external factors, which makes it full of uncertainties. In addition, since micro-videos are mainly uploaded by individuals that lack professional techniques, multiple types of noise could exist that obscure useful information. In this paper, we propose a multimodal variational encoder-decoder (MMVED) framework for micro-video popularity prediction tasks. MMVED learns a stochastic Gaussian embedding of a micro-video that is informative to its popularity level while preserves the inherent uncertainties simultaneously. Moreover, through the optimization of a deep variational information bottleneck lower-bound (IBLBO), the learned hidden representation is shown to be maximally expressive about the popularity target while maximally compressive to the noise in micro-video features. Furthermore, the Bayesian product-of-experts principle is applied to the multimodal encoder, where the decision for information keeping or discarding is made comprehensively with all available modalities. Extensive experiments conducted on a public dataset and a dataset we collect from Xigua demonstrate the effectiveness of the proposed MMVED framework.

description: В работе проанализирована двойственность природы отношений между врачом и пациентом. Данный анализ осуществлен в контексте философских идей М. Бубера. Двойственная природа отношений между врачом и пациентом может препятствовать продуктивному диалогу и скорейшему выздоровлению пациента. Врач, как профессионал, должен найти в этой двойственности «золотую середину», благодаря которой врач выступит по отношению к пациенту как соратник в общем деле борьбы с болезнью. В статье приведен художественный пример гуманного отношения к пациенту из рассказа А.И. Куприна «Чудесный доктор».The article analyses the duality of nature in relationships between the doctor and the patient. This research was conducted in the context of M. Buber’s philosophy. The dual nature of therapeutic relationships may prevent a productive dialogue and a speedy recovery of a patient. As a professional the doctor must find a middle ground in this duality through which he will become an ally in the fight against the patient's disease. The article presents an artistic example of the humane attitude towards a patient from A. Kuprin's story “The wonderful doctor”.

description: We report on the observation of ultralong range interactions in a gas of cold Rubidium Rydberg atoms. The van-der-Waals interaction between a pair of Rydberg atoms separated as far as 100,000 Bohr radii features two important effects: Spectral broadening of the resonance lines and suppression of excitation with increasing density. The density dependence of these effects is investigated in detail for the S- and P- Rydberg states with main quantum numbers n ~ 60 and n ~ 80 excited by narrow-band continuous-wave laser light. The density-dependent suppression of excitation can be interpreted as the onset of an interaction-induced local blockade.

description: We report the results of an extensive spectroscopic survey of galaxies in the roughly 160 square arcminute ACS-GOODS region surrounding the HDF-N. We have identified 787 galaxies or stars with z'<24, R<24.5, or B<25 lying in the region. The spectra were obtained with either the DEIMOS or LRIS spectrographs on the Keck 10m telescopes. The results are compared with photometric redshift estimates and with redshifts from the literature, as well as with the redshifts of a parallel effort led by a group at Keck. Our sample, when combined with the literature data, provides identifications for 1180 sources. We use our results to determine the redshift distributions with magnitude, to analyze the rest-frame color distributions with redshift and spectral type, and to investigate the dependence of the X-ray galaxy properties on the local galaxy density in the redshift interval z=0-1.5. We find the rather surprising result that the galaxy X-ray properties are not strongly dependent on the local galaxy density for galaxies in the same luminosity range.

description: This paper examines the Start-up Success of Spin-off and Symbiosis Company (SSC) using Entrepreneurial Orientation (EO) and Support Service. Notwithstanding the extensive study on start-up firms and Support Service, there is a missing link on how EO impacts Start-up Success, particularly in Malaysia case study. To address such limitation, this paper proposed that Start-up Success of SSC will be improved by EO and Support Service. A total of 120 SSC in Peninsular Malaysia were employed as respondents and data were analyzed using PLS-SEM analysis. The empirical results showed that EO is positively related to Start-up Success and intensify the potentials of Support Service as a moderator. As most of the related literature highlights the importance of Support Service, this study brings new perspectives on how EO is also significant in improving the Start-up Success. In addition, the critical discussion provided in this paper is expected to contribute to the body of knowledge on entrepreneurship studies and act as a future reference on the EO, support service, and SSC.

Subjects: subject: Quantum Physics (quant-ph)

description: The quantum Zeno effect -- suppression of decay by frequent measurements -- was believed to occur only when the response of the detector is so quick that the initial tiny deviation from the exponential decay law is detectable. However, we show that it can occur even for exactly exponentially decaying systems, for which this condition is never satisfied, by considering a realistic case where the detector has a finite energy band of detection. The conventional theories correspond to the limit of an infinite bandwidth. This implies that the Zeno effect occurs more widely than expected so far.

description: Titan has an abundance of lakes and seas, as confirmed by Cassini. Major components of these liquid bodies include methane ($CH_4$) and ethane ($C_2H_6$); however, evidence indicates that minor components such as ethylene ($C_2H_4$) may also exist in the lakes. As the lake levels drop, 5 $μm$-bright deposits, resembling evaporite deposits on earth, are left behind. Here, we provide saturation values, evaporation rates, and constraints on ethylene evaporite formation by using a Titan simulation chamber capable of reproducing Titan surface conditions (89-94 K, 1.5 bar $N_2$). Experimental samples were analyzed using Fourier transform infrared spectroscopy, mass, and temperature readings. Ethylene evaporites form more quickly in a methane solvent than in an ethane solvent or in a mixture of methane/ethane. We measured an average evaporation rate of $(2.8 \pm 0.3) \times 10^{-4} kg \; m^{-2} \; s^{-1}$ for methane and an average upper limit evaporation rate of less than $5.5 \times 10^{-6} kg \; m^{-2} \; s^{-1}$ for ethane. Additionally, we observed red shifts in ethylene absorption bands at 1.630 and 2.121 $μm$ and the persistence of a methane band at 1.666 $μm$.

description: Ti K-edge x-ray absorption near edge spectroscopy (XANES) was used to explore the Ti valence and coordination in Ti-activated sodium alanate. An empirical relationship was established between the Ti valence and the Ti K-edge onset based on a set of standards. This relationship was used to estimate oxidation states of the titanium catalyst in 2 mol% and 4 mol% Ti-doped NaAlH4. These results demonstrate that the formal titanium valence is zero in doped sodium alanate and nearly invariant during hydrogen cycling. A qualitative comparison of the edge fine structure suggests that the Ti is present on the surface in the form of amorphous TiAl3.

description: We present deep maps of dust emission from the edge-on spiral galaxy NGC 891, obtained with the ISOPHOT instrument on board the Infrared Space Observatory in broad band filters with reference wavelengths centered on 170 and 200 micron. Using new processing methods to remove the effects of detector transients from the data, we detect cold dust at high dynamic range. The observed surface brightness distribution and colour profile of the far-infrared (FIR) emission are found to be in good agreement with predictions for their counterparts derived from the model of Popescu et al. (2000a). Thus, NGC 891 is the first galaxy for which an intrinsic distribution of dust and stars could be found which simultaneously accounts for both the optical/near-IR and FIR morphologies.

description: This study posits that the declining industry is a good institutional environment to examine the relationship between ownership structure and firm performance of Vietnamese securities firms. This downturn decreases the return on investment of the industry and creates incentives for managers to expropriate shareholders more severely. In addition, different groups of shareholders recognizing the status of the industry may have their own reactions which are likely to affect firm performance. Using pooled OLS regression with a sample of 240 observations from 56 Vietnamese securities firms over the period from 2009 to 2016, we find supporting evidence of convergence-of-interest with a significantly negative relationship between insider ownership and profitability. In addition, foreign ownership is also positively related to firm performance. Firm size affects positively firm performance while number of employees has a negative impact on profitability.

description: The effectiveness of tax incentives in attracting FDI remains one of the unsettled concepts in public finance. The importance of tax incentives in attraction of internationally mobile capital differs with the jurisdiction of the study and the methodology used in drawing conclusions. This study in reviewing both theoretical and empirical literature seeks to establish the merits and demerits of tax incentives. This is because though they receive a lot of criticism tax incentives continue to be used in most economies. Most of the empirical studies that this study explored concluded that though tax incentives might be important in attracting FDI they are more effective when combined with other non-tax factors. Macroeconomic conditions, infrastructure and strong institutions were found to be important non-tax factors that improve the attractiveness of an economy to FDI. The major weaknesses of using taxes in attracting FDI were discussed using the tax competition and tax harmonisation framework. Here it was noted that the use of tax incentives to attract FDI might improve the welfare of individuals in the jurisdiction that apply the incentives, but have external cost implications for residents in other competing jurisdictions that do not adopt tax incentives.

Solar Ring mission will be the first attempt to routinely monitor and study the Sun and inner heliosphere from a full 360-degree perspective in the ecliptic plane. The current preliminary design of the Solar Ring mission is to deploy six spacecraft, grouped in three pairs, on a sub-AU orbit around the Sun. The two spacecraft in each group are separated by about 30 degrees and every two groups by about 120 degrees. This configuration with necessary science payloads will allow us to establish three unprecedented capabilities: (1) determine the photospheric vector magnetic field with unambiguity, (2) provide 360-degree maps of the Sun and the inner heliosphere routinely, and (3) resolve the solar wind structures at multiple scales and multiple longitudes. With these capabilities, the Solar Ring mission aims to address the origin of solar cycle, the origin of solar eruptions, the origin of solar wind structures and the origin of severe space weather events. The successful accomplishment of the mission will advance our understanding of the star and the space environment that hold our life and enhance our capability of expanding the next new territory of human.

description: The idea initiating the birth of the journal APSTRACT was initiated by András Nábrádi, during a 2005 AGRIMBA1 executive board meeting held in Aberdeen, UK. AGRIMBA is an open international network of academics and professionals from universities and related institutions dealing with education and research in agribusiness (Csapó et al., 2010). Currently, the Network is especially active in Central and Eastern Europe (Heijman, 2015). The main objective of the Network is to set standards based on best practices for programmes it oversees and to accredit them on the basis of these standards. The International MBA Network was established in 1995, by founding members from Wageningen University, Scottish Agricultural College, the Czech University of Life Sciences in Prague, Warsaw Agricultural University, University College Cork and the University of Wolverhampton. Between 2000 and 2009, the following universities joined the Network: Humboldt University Berlin, the University of Debrecen, Arkansas State University, the Agricultural University of Ukraine, the Timiryazev Academy in Moscow, the University of Belgrade and the University of Zagreb (Heijman, 2015). The Universities of Belgorod (Russia) and Kazan (Russia) has also joined the network last year.

description: Background Community mobilisation interventions for HIV prevention among female sex workers (FSWs) aim to organise FSWs for collective action and challenge the structures of power that underlie HIV risk. Assessing intervention impact is challenging because the importance of direct individual exposure to intervention components may decrease over time as change occurs at social-normative, policy and other structural levels. In this paper, the authors examine changes over time in consistent condom use among FSWs in Rajahmundry, Andhra Pradesh, the location of a long-standing community mobilisation intervention. Methods The authors analyse cross-sectional data collected among FSWs at three time points (n¼2276) using respondent-driven sampling. Multiple logistic regression was used to assess the association of programme exposure with consistent condom use and whether this association varied over time. Results The proportion of FSWs having no exposure or only receptive exposure to the intervention decreased over time, while active utilisation increased from 19.4% in 2006 to 48.5% in 2009e2010. Consistent condom use with clients also increased from 56.3% in 2006 to 75.3% in 2009e2010. Multivariate analysis showed that age, age at start of sex work, venue, living conditions and programme exposure were significantly associated with condom use. The positive association between programme exposure and consistent condom use did not vary significantly over time. Conclusions Findings indicate improvements in HIV risk reduction behaviour among FSWs and suggest that the intervention has substantial reach in the FSW population. The intervention’s strategies may be contributing to population-level HIV risk reduction among FSWs.

description: In our busy world, where numerous people starve and where the resources are restricted, it is a key issue to pay particular attention to the topic of prevention and decrease of food loss as well as food wastage.Wastage of food produced and delivered to the end user (customer) is an issue arising globally and nationally as well, which results in efficiency loss at economic level in any case. While the FAO study mentions food waste of the order of 1.3 billion tonnes on a world scale, then the annual quantity of food waste in Hungary is estimated at about 1.8 million tonnes, which contains the waste of every member of the chain from production to consumption. On the basis of the data published by the Hungarian Food Bank (2015), the amount of food waste caused by the population is 400 000 tonnes. In compliance with our objectives, inputs – expressed by non-financial and financial indicators – emerge during production are assigned to the quantity of wasted food. Applying the aforementioned method we would like to make customers realize how many resources (land, water, artificial fertilizer, pesticide, seed and gasoil) are utilized needlessly in food verticum by the end products – at present by different breads they throw out. As our calculations prove by 10% waste of breads the utilization of 5 300 hectares of wheat land and 660 hectares of rye land can be considered unnecessary. By 10% waste of breads the financial value of the utilized resources is altogether 3.25 million EUR. Out of this the financial value of utilized artificial fertilizer is 1.10 million EUR (34%), of utilized pesticide is 1.15 million EUR (35%), of utilized gasoil is 0.70 million EUR (22%) and of utilized seed is 0.30 million EUR (9%). Among different breads, white bread is purchased in the greatest volume by the Hungarian households, from which 121 900 tonnes are bought annually on an average. This quantity is equal to almost the 40% of the annual bread sell. If 10% of purchased white bread is thrown out, it results in useless utilization of 2 676 hectares of wheat land in food verticum. The quantity of utilized water arising form wastage is 15.8 million m3. Further losses emerge as regards material inputs: artificial fertilizer- to the value of 0.50 million EUR, pesticide- to the value of 0.58 million EUR, seed to the value of 0.15 million EUR and gasoil-loss to the value of circa 0.35 million EUR. Totally, material input to the value of 1.58 million EUR is owing to the Hungarian households in case of 10% white bread wastage.

Spectral engineering in multiphoton linear and nonlinear interferometry: the importance of being multimode

description: Parametrische Fluoreszenz (PDC) ist ein nichtlinearer Quanteneffekt, der größtenteils in quantumoptischen Aufbauten, aufgrund der Möglichkeit Paarphotonemissionen auszulösen,verwendet wird. Innerhalb dieser Promotionarbeit wird festgestellt, dass die Spektraleigenschaften des PDC-Effekts eine im Rahmen der Quanteninterferometrie entscheidende Rolle spielen können. Die Argumentation ist in zwei Abschritte unterteilt, in denen lineare und nichtlineare Interferenzsysteme unterschieden und analysiert werden. Als Beispiel von linearer Quanteninterferenz wird die Hong-Ou-Mandel-Interferenz untersucht. In dieser Dissertation wird bewiesen, dass das HOM-Minimum im Koinzidenzprofil sich einem "antibunching" Peak zukehrt, wenn eine Vier- statt Zweiphotoninterferenz vorkommt und falls die Photonen Quantenkorrelationen aufweisen. Außerdem wird die Anwesenheit von schnellen manipulierbaren Schwankungen in der Koinzidenzprofi23l bewiesen, wenn Verschränkung zwischen den zwei Interferometerkanalen ausgelöst wird. Als Vorbild der nicht-linearen Interferometrie wird ein integrierter SU(1,1) Interferometer mathematisch gestaltet und seine Leistungen im Rahmen der Phasensensitivität geprüft. Innerhalb dieser Analyse werden zwei PDC-Prozesse als optisch-parametrische Verstärker, aus denen ein SU(1,1)-Interferometer besteht, genutzt. Es wird bewiesen, dass die Phasensensitivität das Shot-noise-Limit übersteigen kann.
description: The parametric down-conversion (PDC) is a nonlinear optical effect, largely used in quantum optical frameworks because of the possibility to create photon pairs, in some cases characterized by quantum correlations as well as frequency and polarization entanglement.In this thesis, the role of the spectral features of the PDC in quantum interferometry is demonstrated. The argumentation here exposed is split in two parts, distinguishing linear and nonlinear interference phenomena.An example of the first type is the two-photon Hong-Ou-Mandel (HOM) interference, where photons leave the same output door of a beam splitter only if they are identical. In this work it is demonstrated that in the four-photon scenario the coincidence profile changes drastically, and in particular, the HOM dip turns to an antibunching peak if photons undergo quantum correlations. Furthermore, by inducing a spatial entanglement between the channels of the interferometer, the presence of fast oscillations in the coincidence probability is observed. The four photon scenario enables the manipulation of these oscillations as well as the creation of four-photon Bell states. As a paragon of nonlinear interferometry, we mathematically model a realistic integrated SU(1,1) interferometer. In this framework, two PDC waveguides are utilised as optical parametric amplifiers constituting the interferometer. Despite the presence of dispersion, the proposed interferometer can overcome the shot noise limit.
