A Brief Comment on Periphrastic Expressions of Objective Modality in English and Modern Greek: a Comparison
Creators: name: Hatzi, Maria
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1989

description: The aim of this paper is to comment on one of the ways of expressing objective modality in English and Modern Greek, that is, through the use of participial expressions. Reference will also be made to expressions incorporating verbally-derived adjectives and nominals. It will be attempted to point out similarities and de­monstrate, as well as explain, the differences between English and Modern Greek. It is an area which has not been studied as extensive­ly as modal auxiliaries in English. Owing to this, evidence from English has been mostly based on the work of M. Perkins (1983) Modal Expressions in English. Due to complete lack of studies in Greek, though, I was compelled to run informant tests, to check my intui­tions as a native speaker of Greek and my analysis of Greek expre­ssions. These informant tests provided an objective test of my in­tuitive judgments, as well as the evidence, from Modern Greek, on which my present analysis has been based. Before proceeding with the description and comparison of periphrastic expressions in the two languages, I would like to draw your attention to the fact that all conclusions have been drawn with the reserve that the expressions used as examples, which demonstrate different points in this work, have all been taken, and dealt with, in isolation to contextual factors whose significance in determining meaning cannot be denied and/or ignored. Context has not been taken into consideration, though, mainly for two reasons. The first reason is that the par­ticular area of study is, as mentioned above, totally unexplored in Greek and rather new to English research, so there are no sources on the interaction of contextual factors and participial expressions or periphrastic expressions of deontic modality in general. Any existing works on Modal Verbs and Context can only be considered as the starting point of an investigation of the relations between con­textual factors and participial expressions. The second reason is that the analysis of such an interaction is itself, in my opinion, quite a serious task to undertake and cannot just be fitted into this present work as only a comment of secondary importance; it de­serves a fuller treatment.

description: We present a next-to-leading order calculation for the virtual photoproduction of one and two jets in $ep$ collisions. Soft and collinear singularities are extracted using the phase space slicing method. The collinear photon initial state singularity depends logarithmically on the mass of the virtual photon and is absorbed into the virtual photon structure function. An $\overline{MS}$ factorization scheme is defined similarly to the real photon case. Numerical results are presented for HERA conditions using the Snowmass jet definition for inclusive single jet and dijet cross sections. We study the dependence of these cross sections on the transverse energies and rapidities of the jets. Finally, we compare the ratio of the experimentally defined resolved and direct cross sections with recent ZEUS data as a function of the photon virtuality $P^2$.

description: We study the effects of internal symmetries on the decay by bubble nucleation of a metastable false vacuum. The zero modes about the bounce solution that are associated with the breaking of continuous internal symmetries result in an enhancement of the tunneling rate into vacua in which some of the symmetries of the initial state are spontaneously broken. We develop a general formalism for evaluating the effects of these zero modes on the bubble nucleation rate in both flat and curved space-times.

description: The magnetic properties of the two-channel periodic Anderson model for uranium ions, comprised of a quadrupolar and a magnetic doublet are investigated through the crossover from the mixed-valent to the stable moment regime using dynamical mean field theory. In the mixed-valent regime ferromagnetism is found for low carrier concentration on a hyper-cubic lattice. The Kondo regime is governed by band magnetism with small effective moments and an ordering vector $\q$ close to the perfect nesting vector. In the stable moment regime nearest neighbour anti-ferromagnetism dominates for less than half band filling and a spin density wave transition for larger than half filling. $T_m$ is governed by the renormalized RKKY energy scale $μ_{eff}^2 ^2 J^2ρ_0(μ)$.

description: We report HST lightcurve observations of the New Horizons (NH) spacecraft encounter KBO (486958) 2014 MU69 acquired near opposition in July 2017. In order to plan the optimum flyby sequence the NH mission planners needed to learn as much as possible about the target in advance of the encounter. Specifically, from lightcurve data, encounter timing could be adjusted to accommodate a highly elongated, binary, or rapidly rotating target. HST astrometric (Porter et al. 2018) and stellar occultation (Buie et al. 2018) observations constrained MU69's orbit and diameter (21-41 km for an albedo of 0.15-0.04), respectively. Photometry from the astrometric dataset suggested a variability of $\ge$0.3 mags, but they did not determine the period or provide shape information. We strategically spaced 24 HST orbits over 9 days to investigate rotation periods from approximately 2-100 hours and to better constrain the lightcurve amplitude. Until NH detected MU69 in its optical navigation images beginning in August 2018, this HST campaign provided the most accurate photometry to date. The mean variation in our data is 0.15 mags which suggests that MU69 is either nearly spherical (a:b axis ratio of 1:1.15), or its pole vector is pointed near the line of sight to Earth; this interpretation does not preclude a near-contact binary or bi-lobed object. However, image stacks do conclude that MU69 does not have a binary companion $\ge$2000 km with a sensitivity to 29th magnitude. We report with confidence that MU69 is not both rapidly rotating and highly elongated. We note that our results are consistent with the fly-by imagery and orientation of MU69 (Stern et al. 2019). The combined dataset also suggests that within the KBO lightcurve literature there are likely other objects which share a geometric configuration like MU69 resulting in an underestimate of the contact binary fraction for the CC Kuiper Belt.

description: Relaxation phenomena in glasses can be related to jump processes between different minima of the potential energy in the configuration space. These transitions play a key role in the low temperature regime, giving rise to tunneling systems responsible for the anomalous specific heat and thermal conductivity in disordered solids with respect to crystals. By using a recently developed numerical algorithm, we study the potential energy landscape of silica clusters, taking as a starting point the location of first order saddle points. This allows us to find a great number of adjacent minima. We analyze the degree of cooperativity of these transitions and the connection of physical properties with the topology of the configuration space. We also identify two-level systems (pairs of minima constituting a tunneling system) and calculate the quantum mechanical ground state splitting by means of the WKB approximation.

description: No abstracts are to be cited without prior reference to the author.Heterotrophic nanoflagellates (HNF) and heterotrophic bacteria (HB) are major components of the microbial loop in the marine ecosystem. However, little is known about their dynamics and contribution to carbon cycling of the Black Sea ecosystem. To improve our understanding, temporal and spatial changes in abundance and biomass of HNF and HB together with environmental variables were monitored monthly in the southeastern Black Sea during late spring 2010. Seawater samples were taken at 10‐m intervals from the surface to 60m depth at two stations located in neritic and oceanic waters. A Nikon E 600 epifluorescence microscope and image analysis system were used to estimate cell numbers and carbon biomass of HNF and HB. According to our results, HNF and HB abundances range from 3.16 × 102 cells ml–1 to 14.08 × 103 cells ml–1 and 1.12 × 106 cells ml–1 to 3.62 × 106 cells ml–1, respectively. Although the maximum cell number of HNF was present in coastal surface waters in May, the maximum abundance of HB was found above the thermocline in stratified waters in June during the sampling period.

description: We construct multi-center solutions for charged, dilatonic, non-extremal black holes in D=4. When an infinite array of such non-extremal black holes are aligned periodically along an axis, the configuration becomes independent of this coordinate, which can therefore be used for Kaluza-Klein compactification. This generalises the vertical dimensional reduction procedure to include {\it non-extremal} black holes. We then extend the construction to multi-center non-extremal $(D-4)$-branes in $D$ dimensions, and discuss their vertical dimensional reduction.

Energy Demand Modelling of Developing Economies Using MAED-2 with Sectoral Decomposition: Bangladesh Case Study
Creators: name: Sieed, Jubair
Publisher: name: Zenodo
Year: 2019

description: Access to affordable, clean energy and its growing consumption have often been directly linked with socioeconomic development. As one of the fastest developing countries, Bangladesh has been experiencing stable GDP growth with an increasing trend for the last ten years. This growth has initiated excessive demand of energy, especially in the electricity sector. Within just a decade, both the total electricity generation capacity and per capita electricity generations have almost doubled. In order to meet this growing demand and keep pace with the development trend, sectoral demand growth projection for near and long-term planning and execution is essential. Model for Analysis of Energy Demand (MAED)-2 tool provided by International Atomic Energy Agency (IAEA) was used in this study to predict the future energy demand of Bangladesh from the year 2020 to 2050. The energy-economic data of the year 2016 is considered as the base data. Future energy demands based on different socioeconomic, technological and demographic development scenarios have been analyzed to disaggregate the energy demand into a large number of end-use categories corresponding to different goods and services. The overall picture of future energy demand could be farther explored for source-wise optimal energy generation modelling for similar other developing economies.

description: Using Monte Carlo simulations we show that the three-dimensional Ising model with four-spin (plaquette) interactions has some characteristic glassy features. The model dynamically generates diverging energy barriers, which give rise to slow dynamics at low temperature. Moreover, in a certain temperature range the model possesses a metastable (supercooled liquid) phase, which is presumably supported by certain entropy barriers. Although extremely strong, metastability in our model is only a finite-size effect and sufficiently large droplets of stable phase divert evolution of the system toward the stable phase. Thus, the glassy transitions in this model is a dynamic transition, preceded by a pronounced peak in the specific heat.

description: A Doença de Parkinson (DP) é uma doença neurodegenerativa com alterações motoras e não motoras que acomete, especialmente, a população idosa. Atualmente, tanto o diagnóstico como o acompanhamento da doença têm um caráter puramente clínico. Assim, diversos são os estudos que buscam desenvolver e estabelecer métodos mais objetivos, como o uso, por exemplo, de sensores inerciais para quantificar e diagnosticar o tremor. Neste sentido, o presente trabalho objetivou investigar quantitativamente, por meio de sensores inerciais, o comportamento da amplitude do tremor de repouso do punho em indivíduo com DP, visando caracterizá-lo sob a perspectiva de cenários distintos de intervenção clínica, dados pela combinação entre os estados da técnica de estimulação cerebral profunda (DBS) e os períodos de atuação do medicamento antiparkinsoniano no organismo do indivíduo. Para tanto, delineou-se um estudo comparativo em que se avaliou os sinais inerciais do lado mais acometido do punho de um indivíduo com DP. Dentre os diferentes cenários de intervenção analisados, aqueles, nos quais a pessoa estava sob efeito do medicamento antiparkinsoniano, obtiveram uma redução significativa (p < 0,05) na amplitude do tremor de repouso independentemente do sensor considerado.

description: The Hubble Space Telescope (HST) measured the colors of eight Kuiper Belt Objects (KBOs) that will be observed by the New Horizons spacecraft including its 2019 close fly-by target the Cold Classical KBO (486958) 2014 MU69. We find that the photometric colors of all eight objects are red, typical of the Cold Classical dynamical population within which most reside. Because 2014 MU69 has a similar color to that of other KBOs in the Cold Classical region of the Kuiper Belt, it may be possible to use the upcoming high-resolution New Horizons observations of 2014 MU69 to draw conclusions about the greater Cold Classical population. Additionally, HST found none of these KBOs to be binary within separations of ~0.06 arcsec (~2000 km at 44 AU range) and Δm less than or equal to 0.5. This conclusion is consistent with the lower fraction of binaries found at relatively wide separations. A few objects appear to have significant photometric variability, but our observations are not of sufficient signal-to-noise or time duration for further interpretation.

description: Within the composite operator formalism we derive a formula for the pion decay constant $f_π$, as defined directly from the residue at the pion pole of the meson propagator, rather than from the matrix element of the axial current. The calculation is performed under some simplifying assumptions, and we verify the complete consistency with soft-pion results, in particular with the Adler-Dashen relation. The formula one obtains for (the pole-defined) $f_π^2$ differs from the previous Pagels-Stokar expression by an additive term, and it still provides $f_π^2$ in terms of the quark self-energy. We make some numerical estimates leading to $(30 ÷40)%$ deviation for $f_π^2$ with respect to the Pagels-Stokar formula.

description: When non-magnetic impurities are introduced in a d-wave superconductor, both thermodynamic and spectral properties are strongly affected if the impurity potential is close to the strong resonance limit. In addition to the scalar impurity potential, the charge carriers are also spin-orbit coupled to the impurities. Here it is shown that (i) close to the unitarity limit for the impurity scattering, the spin-orbit contribution is of the same order of magnitude than the scalar scattering and cannot be neglected, (ii) the spin-orbit scattering is pair-breaking and (iii) induces a small id_xy component to the off-diagonal part of the self-energy.

description: As nearby neighbors to the Milky Way, the Large and Small Magellanic Clouds (LMC and SMC) provide a unique opportunity to study star formation in the context of their galactic ecosystems. Thousands of young stellar objects (YSOs) have been characterized with large-scale Spitzer and Herschel surveys. In this paper, we present new near-IR spectroscopy of five high-mass YSOs in the LMC and one in the SMC. We detect multiple hydrogen recombination lines, as well as He I 2.058 $μ$m, H$_2$, [Fe II], and [S III] in these highly excited sources. We estimate the internal extinction of each source and find that it is highest for sources with the youngest evolutionary classifications. Using line ratios, we assess the dominant excitation mechanism in the three sources where we detect both H$_2$ 2.12 $μ$m and [Fe II] 1.64 $μ$m. In each case, photoexcitation dominates over shock excitation. Finally, we detect CO bandhead absorption in one of our LMC sources. While this feature is often associated with evolved stars, this object is likely young with strong PAH and fine-structure emission lines tracing an H II region detected at longer wavelengths. Compared to high-mass YSOs in the Galaxy, our sources have higher bolometric and line luminosities, consistent with their selection as some of the brightest sources in the LMC and SMC.

description: No abstracts are to be cited without prior reference to the author.Phytoplankton variability is mostly analysed on seasonal and decadal time‐scales. Variability at shorter time‐scales is typically regarded as noise in such analyses. Algal bloom phenomena often develop at shorter time‐scales. Better understanding of short‐term phytoplankton variability is needed both to reduce the noise in seasonal and trend analyses and to predict blooms. We have analysed variability at time‐scales shorter than a month in timeseries of chlorophyll a, suspended particulate matter, salinity, and temperature from four mooring sites in the North Sea. The dataseries cover several years at an hourly resolution. We used wavelet analysis to characterize time‐scales of variability and correlations between variables. We compared how time‐scales and correlations change with the seasons and between sites. Turbulent mixing by tides and wind appears to be the dominant factor controlling mesoscale variability for all four variables. Dominant timescales of chlorophyll a variability are 6 h, 12 h, and 15 d in our data, which correspond to the timescales of tides. Most of the time chlorophyll a variability is positively correlated with variability of suspended matter concentrations. This suggests that sinking and vertical mixing have a stronger effect on phytoplankton variability than light limitation of growth rates, except during the start of the spring bloom.

description: Nanolaminated materials are important because of their exceptional properties and wide range of applications. Here, we demonstrate a general approach to synthesize a series of Zn-based MAX phases and Cl-terminated MXenes originating from the replacement reaction between the MAX phase and the late transition metal halides. The approach is a top-down route that enables the late transitional element atom (Zn in the present case) to occupy the A site in the pre-existing MAX phase structure. Using this replacement reaction between Zn element from molten ZnCl2 and Al element in MAX phase precursors (Ti3AlC2, Ti2AlC, Ti2AlN, and V2AlC), novel MAX phases Ti3ZnC2, Ti2ZnC, Ti2ZnN, and V2ZnC were synthesized. When employing excess ZnCl2, Cl terminated MXenes (such as Ti3C2Cl2 and Ti2CCl2) were derived by a subsequent exfoliation of Ti3ZnC2 and Ti2ZnC due to the strong Lewis acidity of molten ZnCl2. These results indicate that A-site element replacement in traditional MAX phases by late transition metal halides opens the door to explore MAX phases that are not thermodynamically stable at high temperature and would be difficult to synthesize through the commonly employed powder metallurgy approach. In addition, this is the first time that exclusively Cl-terminated MXenes were obtained, and the etching effect of Lewis acid in molten salts provides a green and viable route to prepare MXenes through an HF-free chemical approach.

description: We obtain the finite-temperature unconditional master equation of the density matrix for two coupled quantum dots (CQD) when one dot is subjected to a measurement of its electron occupation number using a point contact (PC). To determine how the CQD system state depends on the actual current through the PC device, we use the so-called quantum trajectory method to derive the zero-temperature conditional master equation. We first treat the electron tunneling through the PC barrier as a classical stochastic point process (a quantum-jump model). Then we show explicitly that our results can be extended to the quantum-diffusive limit when the average electron tunneling rate is very large compared to the extra change of the tunneling rate due to the presence of the electron in the dot closer to the PC. We find that in both quantum-jump and quantum-diffusive cases, the conditional dynamics of the CQD system can be described by the stochastic Schrödinger equations for its conditioned state vector if and only if the information carried away from the CQD system by the PC reservoirs can be recovered by the perfect detection of the measurements.

description: No abstracts are to be cited without prior reference to the author.Phytoplankton is one of the most important indicators of ecological status of a water body. In recent decades, active hydroengineering works have been carried out in Vyborg Bay. During the first period of work in 1997–1999, phytoplankton quantitative development in the water area near the construction of Port Vysotsk corresponded with levels in the mesotrophic water body. Phytoplankton abundance varied from 39 to 79 million cells l–1 and biomass was 2–4 g m–3. Bluegreen algae constituted the major (50%) portion of biomass. Chlorophyll a concentration was 89 mg m–3. In 2008–2010 in this area phytoplankton abundance varied from 70 to 193 million cells l–1 and biomass was 5–10 g m–3. The blue‐green algae constituted ca. 80% of total biomass. The freshwater green algae Dictyosphaerium pulchellum, Sphaerocystis schroederi, and Tetraedron spp. had disappeared. Chlorophyll a concentration was in the range 15–30 mg m–3. Thus, in recent decades the phytoplankton development in the study area increased to eutrophic levels. This increase was accompanied by an enhancement of the role of bluegreen algae, while the role of freshwater green algae declined. These changes in phytoplankton were probably caused by natural factors (more intensive inflow of salt‐ and nutrient-rich deep waters from western Gulf of Finland) as well as by anthropogenic impacts mainly connected with additional nutrient supply from the bottom during hydroengineering works.

description: We construct a time-dependent expression of the computational complexity of a quantum system which consists of two conformal complex scalar field theories in d dimensions coupled to constant electric potentials and defined on the boundaries of a charged AdS black hole in (d+1) dimensions. Using a suitable choice of the reference state, Hamiltonian gates and the metric on the manifold of unitaries, we find that the complexity grows linearly for a relatively large interval of time. We also remark that for scalar fields with very small charges the rate of variation of the complexity cannot exceed a maximum value known as the Lloyd bound.

description: We use astrometry, broad-band photometry and variability information from the Data Release 2 of ESA's Gaia mission (GDR2) to identify members of the Orphan Stream (OS) across the whole sky. The stream is traced above and below the celestial equator and in both Galactic hemispheres, thus increasing its visible length to ~ 210 degrees equivalent to ~150 kpc in physical extent. Taking advantage of the large number of RR Lyrae stars in the OS, we extract accurate distances and proper motions across the entire stretch of the tidal debris studied. As delineated by the GDR2 RR Lyrae, the stream exhibits two prominent twists in its shape on the sky which are accompanied by changes in the tangential motion. We complement the RR Lyrae maps with those created using GDR2 Red Giants and the DECam Legacy Survey Main Sequence Turn-Off stars. The behavior of the OS track on the sky is consistent across all three tracers employed. We detect a strong non-zero motion in the across-stream direction for a substantial portion of the stream. Such a misalignment between the debris track and the streaming velocity cannot be reproduced in a static gravitational potential and signals an interaction with a massive perturber.

description: No abstracts are to be cited without prior reference to the author.Phytoplankton samples were collected in summer 2005–2010 during research cruises of the RV “Baltica” in the southern Baltic Proper with the aim of investigating changes in the summer phytoplankton community in connection with environmental factors. The similarity of taxonomic composition between samples was estimated by hierarchical agglomerative clustering analysis according to the Bray–Curtis measure of similarity using PRIMER v.6 software. Two groups of samples were identified at a similarity level of 40%. The first group included 84% of the stations and was characterized by dominance of nanoplanktonic flagellates (cryptophytes, Pyramimonas spp., unidentified flagellates), diatoms (Actinocyclus octonarius, Chaetoceros danicus), and Mesodinium rubrum. Mean phytoplankton biomass was 360 μg l–1, with maximum of 831 and minimum of 97 μg l–1. Water temperature ranged from 14.4°C to 20.5°C. The second group consisted of all samples from July 2005 and samples from the Gdańsk Basin collected in August 2010. In this case water temperature was generally higher, ranging from 16.6°C to 23.3°C. Blue‐green algae, such as Aphanizomenon sp. and Nodularia spumigena, dominated the phytoplankton community. The mean biomass value for this group was 765 μg l–1, with the highest biomass value of 2581 μg l–1, which was also the highest found in all investigated material. Aggregation of 84% samples from five years of investigations into one group with high taxonomic similarity suggests that the summer phytoplankton community was homogeneous and “conservative” over a large area of the Baltic Proper, and in the period of last semi‐decade seemed to be unaffected by the ongoing global changes.

description: We present disc wind models aimed at reproducing the main features of the strong Na I resonance line P-Cygni profiles in the rapidly-accreting pre-main sequence FU Ori objects. We conducted Monte Carlo radiative transfer simulations for a standard magnetocentrifugally driven wind (MHD) model and our own "Genwind" models, which allows for a more flexible wind parameterisation. We find that the fiducial MHD wind and similar Genwind models, which have flows emerging outward from the inner disc edge, and thus have polar cavities with no absorbing gas, cannot reproduce the deep, wide Na I absorption lines in FU Ori objects viewed at low inclination. We find that it is necessary to include an "inner wind" to fill this polar cavity to reproduce observations. In addition, our models assuming pure scattering source functions in the Sobolev approximation at intermediate viewing angles ($30^{\circ} \lesssim i \lesssim 60^{\circ}$) do not yield sufficiently deep line profiles. Assuming complete absorption yields better agreement with observations, but simple estimates strongly suggest that pure scattering should be a much better approximation. The discrepancy may indicate that the Sobolev approximation is not applicable, possibly due to turbulence or non-monotonic velocity fields; there is some observational evidence for the latter. Our results provide guidance for future attempts to constrain FU Ori wind properties using full MHD wind simulations, by pointing to the importance of the boundary conditions necessary to give rise to an inner wind, and by suggesting that the winds must be turbulent to produce sufficiently deep line profiles.

An extended pair tunneling model: studies on bilayer splitting and some superconducting state properties

description: We consider an extended version of the pair tunneling model including interlayer single particle hopping (ISPH) as a complementary process to pair tunneling. The normal state gap, as found in cuprates, is taken to suppress the effective ISPH in conformity with the experimental observations, and this in turn enhances the pair tunneling process. The effective ISPH involves a probability factor P for which we consider two choices and provide phenomenological arguments in favour of them. We address the issue of bilayer splitting by calculating the spectral density function and corresponding photoemission intensity curves and show that our calculations conform with the absence of bilayer splitting observed in ARPES experiments on Bi2212. We have also studied the temperature variation of the superconducting gap and ratio of the superconducting gap to T_c. Our results, obtained for both the choices of P, are reasonably in good agreement with those from experiments on cuprate superconductors. A linear T-dependent choice of P, however, yields a precise match to the experimantal data of the temperature varying superconducting gap.

On the dynamics of reaction coordinates in classical, time-dependent, many-body processes

description: Complex microscopic many-body processes are often interpreted in terms of so-called `reaction coordinates', i.e. in terms of the evolution of a small set of coarse-grained observables. A rigorous method to produce the equation of motion of such observables is to use projection operator techniques, which split the dynamics of the observables into a main contribution and a marginal one. The basis of any derivation in this framework is the classical (or quantum) Heisenberg equation for an observable. If the Hamiltonian of the underlying microscopic dynamics and the observable under study do not explicitly depend on time, this equation is obtained by a straight-forward derivation. However, the problem is more complicated if one considers Hamiltonians which depend on time explicitly as e.g. in systems under external driving, or if the observable of interest has an explicit dependence on time. We use an analogy to fluid dynamics to derive the classical Heisenberg picture and then apply a projection operator formalism to derive the non-stationary generalized Langevin equation for a coarse-grained variable. We show, in particular, that the results presented for time-independent Hamiltonians and observables in J. Chem. Phys. 147, 214110 (2017) can be generalized to the time-dependent case.
