description: The food industry is, according to the International Classification of Production in OECD countries, one of the low technology sectors. The present study has confirmed that there was a positive and significant correlation between the economic situation and the innovation activity in this industry. Moreover, this relationship is cyclical in nature and it substantially affects the decisions on innovation activity. This follows from the fact that the largest part of production belongs to low technology sectors in every economy, which is typical for developing countries. For this reason, the primary objective of the study was to try to search for statistically significant directions and the impact of business cycle on the behavior of innovative food companies in Poland. Analyses were performed on data from 671 companies belonging to the food processing sector and the research methodology was based on probit modeling. / Synopsis. Przemysł spożywczy należy według międzynarodowej klasyfikacji działalności produkcyjnej w krajach OECD do sektorów niskich technologii. Otrzymane wyniki badań potwierdziły, że istnieje pozytywna i istotna korelacja między koniunkturą gospodarczą a aktywnością innowacyjną przedsiębiorstw tego przemysłu. Co więcej zależność ta posiada cykliczny charakter i istotnie wpływa na decyzje innowacyjne przedsiębiorstw. Wynika to z faktu, że w gospodarce krajowej największa część produkcji przypada na niskie technologie, co jest typowe dla państw rozwijających się. Podstawowym celem prowadzonych badań była próba poszukiwania statystycznie istotnych kierunków oraz siły wpływu faz cyklu koniunkturalnego na zachowania innowacyjne przedsiębiorstw przemysłu spożywczego w Polsce. Analizy wykonano na bazie 671 przedsiębiorstw zaliczanych do sektora produkcji artykułów spożywczych, a metodyka badawcza była oparta na modelowaniu probitowym.

description: We show that symmetries and gauge symmetries of a large class of 2-dimensional sigma models are described by a new type of a current algebra. The currents are labeled by pairs of a vector field and a 1-form on the target space of the sigma model. We compute the current-current commutator and analyse the anomaly cancellation condition, which can be interpreted geometrically in terms of Dirac structures, previously studied in the mathematical literature. Generalized complex structures correspond to decompositions of the current algebra into pairs of anomaly free subalgebras. Sigma models that we can treat with our method include both physical and topological examples, with and without Wess-Zumino type terms.

description: Deep Reinforcement Learning approaches to Online Portfolio Selection have grown in popularity in recent years. The sensitive nature of training Reinforcement Learning agents implies a need for extensive efforts in market representation, behavior objectives, and training processes, which have often been lacking in previous works. We propose a training and evaluation process to assess the performance of classical DRL algorithms for portfolio management. We found that most Deep Reinforcement Learning algorithms were not robust, with strategies generalizing poorly and degrading quickly during backtesting.

description: The proposals concerning the CAP 2014-2020, presented by the European Commission in 2011, suggest that the nature of this policy will not be substantially altered. This implies that the CAP still will not offer sufficiently efficient and effective instruments supporting structural changes in the Polish agriculture. Especially worrying, not only from the Polish perspective but also for the whole EU’s agriculture, are the proposals on greening direct payments. Increased obligations concerning the environmental protection and introduction of requirements leading de facto to setting aside 7% of the UAA in agricultural holdings can significantly reduce the competitiveness of the EU’s agriculture, already being systematically decreased by high production costs resulting both from labour costs and from the necessity of bearing the costs of observing the norms and limitations concerning the natural environment and the animal welfare. / Synopsis. Propozycje przedłożone przez Komisję Europejską w 2011 r. w odniesieniu do kształtu Wspólnej Polityki Rolnej 2014-2020 sugerują, iż charakter tej polityki nie ulegnie zasadniczym zmianom. Oznacza to, iż w dalszym ciągu WPR nie będzie oferowała wystarczają co efektywnych i skutecznych instrumentów wspierania przemian strukturalnych w polskim rolnictwie. Szczególnie niepokojące, nie tylko z punktu widzenia polskiego rolnictwa, ale również w odniesieniu do konkurencyjności sektora rolnego całej Wspólnoty, są propozycje dotyczące zazielenienia płatności bezpośrednich. Podniesienie zobowiązań związanych z ochroną środowiska oraz wprowadzenie wymogów oznaczających de facto konieczność odłogowania 7% UR gospodarstwa rolnego może znaczą co zmniejszyć konkurencyjność unijnego rolnictwa, którą już teraz systematycznie ograniczają wysokie koszty produkcji, wynikające zarówno z kosztów pracy, jak również z konieczności ponoszenia kosztów dotyczących przestrzegania norm i ograniczeń w zakresie środowiska naturalnego i dobrostanu zwierząt.

description: We study statistical relationships between bubble walls in cosmological first-order phase transitions. We consider the conditional and joint probabilities for different points on the walls to remain uncollided at given times. We use these results to discuss space and time correlations of bubble walls and their relevance for the consequences of the transition. In our statistical treatment, the kinematics of bubble nucleation and growth is characterized by the nucleation rate and the wall velocity as functions of time. We obtain general expressions in terms of these two quantities, and we consider several specific examples and applications.

description: The higher order harmonic flow observables $v_n$ ($n > 3$) and their non-linear responses to the initial state anisotropy have the strong potential to constrain shear and bulk viscosity to entropy ratios because of different sensitivities for various stages of heavy-ion collisions. The measurements of the flow coefficients and the non-linear coefficients up to the ninth and fifth harmonic, respectively, are presented in Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02\,\mathrm{TeV}$ for charged hadrons. In addition, the results of $p_\mathrm{T}$-differential non-linear flow modes for $π^\pm$, $\mathrm{K}^\pm$, $\mathrm{p}+\mathrm{\bar{p}}$, $\mathrm{K}_s^0$, $Λ+\barΛ_s^0$ and $ϕ$ are presented. The results are compared to the same measurements at 2.76 TeV and calculations from state of the art hydrodynamic models.

description: In China and India, the increasing demand for agricultural commodities in the last decade resulted in a significant increase in demand for mineral fertilizers. The article analyzed the changes that have occurred in the market of mineral fertilizers in these countries. It describes the evolution of production, foreign trade and consumption of mineral fertilizers and the share of these countries in the global market. The article uses data from the International Fertilizer Industry Association (IFA) and the United States Geological Survey (USGS), which were used to calculate the basic indicators of market balance. The study showed that the growing demand for mineral fertilizers in China has caused an increase in production to a level that allowed for a complete cancellation of imports and for an allocation of surpluses for exports. In India, a similar growth rate in demand for mineral fertilizers has caused a slight increase in production, while imports had to be increased several times. This has led to a significant pressure on the global supply of mineral fertilizers and contributed to drastic price increases in 2007-2008. / Synopsis. W Chinach i Indiach wzrost zapotrzebowania na surowce rolne w ostatniej dekadzie spowodował istotne zwiększenie popytu na nawozy mineralne. W artykule przeanalizowano zmiany, jakie zaszły na rynku nawozów mineralnych w tych krajach. Opisano zmiany produkcji, handlu zagranicznego oraz zużycia nawozów mineralnych. Określono udział tych krajów w rynku światowym. Wykorzystano dane International Fertilizer Industry Association (IFA) oraz United States Geological Service (USGS), które posłużyły do obliczenia podstawowych wskaźników bilansu rynkowego. Przeprowadzone badania wykazały, że w Chinach rosnący popyt na nawozy mineralne spowodował wzrost produkcji do poziomu, który pozwolił na całkowitą rezygnację z importu i przeznaczanie nadwyżek podaży na eksport. W Indiach, przy podobnej dynamice wzrostu popytu na nawozy mineralne, produkcja wzrosła nieznacznie, a import musiał być zwiększony kilkukrotnie. Doprowadziło to do istotnego zwiększenia presji na światową podaż nawozów mineralnych i przyczyniło się do drastycznych podwyżek cen w latach 2007-2008.

description: Binding interaction between the small antitumor drug Hydroxyurea (HU) and Bovine Hemoglobin (BHb) has been explored in details from multi-spectroscopic and computational studies. The formation of ground state complex between BHb and HU has been suggested from the electronic UV–Vis and steady-state fluorescence spectroscopic studies. The quenching in fluorescence of BHb in presence of HU at varied concentrations has been analyzed from the SV plots. Static type of quenching has been suggested from time-resolved fluorescence spectroscopic studies. Binding parameters associated with the BHb-HU complex have also been estimated from the temperature dependent fluorescence spectroscopic studies. Alterations in the micro-environment of the Tyr and Trp residues of BHb in presence of HU have been observed from the synchronous fluorescence measurement. The result obtained from CD spectroscopic measurements signify partial unfolding in the secondary structure of BHb due to binding with HU molecule. The experimental observations are supported by theoretical studies. Molecular docking and molecular dynamics simulations have been performed to investigate the structural stability and compactness of BHb in the binding interaction between BHb and HU. The interaction of BHb with HU is expected to provide fundamental insights towards understanding the therapeutic effectiveness of HU upon interaction with BHb used in chemo-, radio therpeutic procedures and also in the treatment of SCD.

description: We study in detail the interesting dynamical symmetry and its applications in various atomic systems with electromagnetically induced transparency (EIT) in this paper. By discovering the symmetrical Lie group of various atomic systems, such as single-atomic-ensemble composed of complex $m$-level $(m>3)$ atoms, and $two$-atomic-ensemble and even multi-atomic-ensemble system composed of of $three$-level atoms etc., one can obtain the general definition of dark-state polaritons (DSPs), and then the dark-states of these different systems. The symmetrical properties of the multi-level system and multi-atomic-ensemble system are shown to be dependent on some characteristic parameters of the EIT system. Furthermore, a controllable scheme to generate quantum entanglement between lights or atoms via quantized DSPs theory is discussed and the robustness of this scheme is analyzed by confirming the validity of adiabatic passage conditions in this paper.

Feature-based methodologies for milling process modeling in Virtual Machining
Creators: name: Wang, Jue
Publisher: name: University of British Columbia
Year: 2010

description: Virtual Machining is used to simulate the machining process prior to actual machining, thereby avoiding costly test trials on the shop floor. To realize Virtual Machining, two major methodologies, Geometric Modeling and Process Modeling, are required. In geometric modeling, Cutter/Workpiece Engagements (CWEs) are extracted to support force prediction in process modeling. In process modeling, the physics of the machining process, such as cutting forces, torque and power, are predicted by integrating the laws of the metal cutting process with CWEs generated in geometric modeling. Based on these predictions, process parameters can be optimized for productivity. Methodologies in geometric modeling for CWE extraction require a large number of calculations, however, the robustness and computational stability of these approaches is a significant challenge. In this thesis, methodologies are developed to address these problems in CWE extraction for the milling process. These methodologies achieve computational efficiency and stability by reducing the number of intersections that need to be performed and by parallelizing computational activities in the process of CWE extraction. A feature-based approach is presented for CWE extraction in 2 1/2 D end milling by introducing in-process machining features into process modeling. In hole milling, an analytical approach is presented for CWE extraction, and a NURBS based approach is developed for generating the swept volume for in-process workpiece modeling. A Multi-Agent System based framework is developed to improve efficiency of the CWE calculation, by parallelizing computational activities and utilizing free resources over a network.

description: Gaussian processes are a powerful framework for quantifying uncertainty and for sequential decision-making but are limited by the requirement of solving linear systems. In general, this has a cubic cost in dataset size and is sensitive to conditioning. We explore stochastic gradient algorithms as a computationally efficient method of approximately solving these linear systems: we develop low-variance optimization objectives for sampling from the posterior and extend these to inducing points. Counterintuitively, stochastic gradient descent often produces accurate predictions, even in cases where it does not converge quickly to the optimum. We explain this through a spectral characterization of the implicit bias from non-convergence. We show that stochastic gradient descent produces predictive distributions close to the true posterior both in regions with sufficient data coverage, and in regions sufficiently far away from the data. Experimentally, stochastic gradient descent achieves state-of-the-art performance on sufficiently large-scale or ill-conditioned regression tasks. Its uncertainty estimates match the performance of significantly more expensive baselines on a large-scale Bayesian optimization task.

description: Interaction behaviour of an anticancer drug, saracatinib (SCB) with human serum albumin (HSA), the major carrier protein in human blood circulation was investigated using fluorescence and absorption spectroscopy as well as computational methods. Analysis of the fluorescence quenching data along with absorption results confirmed the complex formation between SCB and HSA, based on the inverse correlation of the Stern-Volmer constant (KSV) with temperature and hyperchromic effect in the absorption spectra. Moderate binding affinity between SCB and HSA was evident from the binding constant, Ka value (1.08–0.74 × 104 M−1), while the SCB − HSA complexation was anticipated to be stabilized by hydrophobic and van der Waals interactions along with hydrogen bonds, as revealed from the thermodynamic data (ΔS = + 29.40 J mol−1 K−1 and ΔH = – 13.90 kJ mol−1). Addition of SCB to HSA significantly defended the thermal denaturation of the protein, though it perturbed the surrounding medium around Tyr and Trp residues. Site marker displacement results elucidated Sudlow's site I, positioned in subdomain IIA of HSA as the preferred binding site of SCB, which was well supported by molecular docking. Molecular dynamics simulation results suggested the stability of the SCB–HSA complex.

description: In this work we consider the hydrodynamic behavior of a coupled electron-phonon fluid, focusing on electronic transport under the conditions of strong phonon drag. This regime occurs when the rate of phonon equilibration due to e.g. umklapp scattering is much slower than the rate of normal electron-phonon collisions. Then phonons and electrons form a coupled out-of-equilibrium state where the total quasi-momentum of the electron-phonon fluid is conserved. A joint flow-velocity emerges as a collective hydrodynamic variable. We derive the equation of motion for this fluid from the underlying microscopic kinetic theory and elucidate its effective viscosity and thermal conductivity. In particular, we derive decay times of arbitrary harmonics of the distribution function and reveal its corresponding super-diffusive relaxation on the Fermi surface. We further consider several applications of this theory to magneto-transport properties in the Hall-bar and Corbino-disk geometries, relevant to experiments. In our analysis we allow for general boundary conditions that cover the crossover from no-slip to no-stress flows. Our approach also covers a crossover from the Stokes to the Ohmic regime under the conditions of the Gurzhi effect. In addition, we consider the frequency dependence of the surface impedance and non-equilibrium noise. For the latter, we notice that in the diffusive regime, a Fokker-Planck approximation, applied to the electron-phonon collision integral in the Eliashberg form, reduces it to a differential operator with Burgers nonlinearity. As a result, the non-equilibrium distribution function has a shock-wave structure in the energy domain. The consequence of this behavior for the Fano factor of the noise is investigated. In conclusion we discuss connections and limitations of our results in the context of recent electron-phonon drag measurements in Dirac and Weyl semimetals.

description: We use a new technique to extract the spectrum of a supernova from that of the contaminating background of its host galaxy, and apply it to the specific case of high-redshift Type Ia supernova (SN Ia) spectroscopy. The algorithm is based on a two-channel iterative technique employing the Richardson-Lucy restoration method and is implemented in the IRAF code 'specinholucy'. We run the code both on simulated (SN Ia at z=0.5 embedded in a bright host galaxy) and observed (SNe Ia at various phases up to z=0.236) data taken with VLT+FORS1 and show the advantages of using such a deconvolution technique in comparison with less elaborate methods. This paper is motivated by the need for optimal supernova spectroscopic data reduction in order to make meaningful comparisons between the low and high-redshift SN Ia samples. This may reveal subtle evolutionary and systematic effects that could depend on redshift and bias the cosmological results derived from comparisons of local and high-z SNe Ia in recent years. We describe the various aspects of the extraction in some detail as guidelines for the first-time user and present an optimal observing strategy for successful implementation of this method in future high-z SN Ia spectroscopic follow-up programmes.

Year: 2017
Subjects: subject: hearing aid

subject: cocktail party effect

description: The ideal binary time-frequency masking is a signal separation technique that keeps the mixture energy in the time-frequency units where local SNR (Signal-to-Noise Ratio) exceeds a certain threshold and rejects mixture energy in other time-frequency units. A binary mask is defined in time-frequency domain as a matrix of binary numbers, and the elements of the speech signal in time-frequency domains are referred to as T-F units, through this mask, the frequency band of the received signal is decomposed (simulating the human acoustic system) by using special filters, and the energies of the signal are computed in the time domain. The IBM would compare the SNR within each T-F unit with a threshold of units of the target signal in dB, the units with SNR exceeding the threshold would be signed as 1, otherwise as 0. The IBM gain from the segregated signal would be applied again to the mixture of target speech and noise. Some experiments studied the effect and results of the binary masking approach for normal hearing and hearing-impaired subjects, in this research work, we submitted an experiment done by (Di Lang Wang, 2009) to prove the effect of the IBM on the Speech-reception Threshold SRT for Normal and Hearing-Impaired listeners, as well as, discuss the results of the experiment and how the IBM effectively improved the speech intelligibility specially for the Hearing-Impaired individuals in the Cafeteria Background noise, the results also proved that the Speech intelligibility has improved in the low-frequency region by the IBM more than the high-frequency region. In the future work we would discuss the integration of the IBM technique within the cochlear implants.

description: The initiation of giant electrical discharges called as "gigantic jets" connecting thunderclouds to the ionosphere is investigated by numerical simulation method in this paper. Using similarity relations, the triggering conditions of streamer formation in laboratory situations are extended to form a criterion of initiation of gigantic jets. The energy source causing a gigantic jet is considered due to the quasi-electrostatic field generated by thunderclouds. The electron dynamics from ionization threshold to streamer initiation are simulated by the Monte Carlo technique. It is found that gigantic jets are initiated at a height of ~18-24 km. This is in agreement with the observations. The method presented in this paper could be also applied to the analysis of the initiation of other discharges such as blue jets and red sprites.

description: We propose a new method of spin squeezing of atomic spin, based on the interactions between atoms and off-resonant light which are known as paramagnetic Faraday rotation and fictitious magnetic field of light. Since the projection process, squeezed light, or special interactions among the atoms are not required in this method, it can be widely applied to many systems. The attainable range of the squeezing parameter is S^{-2/5}, where S is the total spin, which is limited by additional fluctuations imposed by coherent light and the spherical nature of the spin distribution.

description: In a recent paper [TMP, 200:1 (2019), 966--984] by the authors, a series of integrable discrete autonomous equations on a square lattice with a non-standard structure of generalized symmetries is constructed. We build modified series by using discrete non-point transformations. We use both non-invertible linearizable transformations and non-point transformations invertible on solutions of the discrete equation. As a result, we get several series of new examples of discrete equations along with their generalized symmetries and master symmetries. The generalized symmetries constructed give new integrable examples of five- and seven-point differential-difference equations together with their master symmetries. In the case of discrete equations, the method of constructing non-invertible linearizable transformations by using conservation laws is considered, apparently, for the first time.

description: The rise of mobile apps has brought greater convenience and many options for users. However, many apps use analytics services to collect a wide range of user interaction data, with privacy policies often failing to reveal the types of interaction data collected or the extent of the data collection practices. This lack of transparency potentially breaches data protection laws and also undermines user trust. We conducted an analysis of the top 20 analytic libraries for Android apps to identify common practices of interaction data collection and used this information to develop a standardized collection claim template for summarizing an app's data collection practices wrt. user interaction data. We selected the top 100 apps from popular categories on Google Play and used automatic static analysis to extract collection evidence from their data collection implementations. Our analysis found that a significant majority of these apps actively collected interaction data from UI types such as View (89%), Button (76%), and Textfield (63%), highlighting the pervasiveness of user interaction data collection. By comparing the collection evidence to the claims derived from privacy policy analysis, we manually fact-checked the completeness and accuracy of these claims for the top 10 apps. We found that, except for one app, they all failed to declare all types of interaction data they collect and did not specify some of the collection techniques used.

description: Expansion als Eigenschaft von Graphen und im Besonderen Expander-Graphen mit beschränktem Knotengrad sind ein zentrales Forschungsthema in der Kombinatorik und in den theoretischen Computerwissenschaften mit vielen Anwendungen und Verbindungen zu anderen Gebieten der Mathematik. In den letzten Jahren gab es gemeinsame Bemühungen, diese reichhaltige und fruchtbare Theorie auf höherdimensionale Fragestellungen zu erweitern und zu verallgemeinern. In dieser Arbeit werden einige der aktuellen Entwicklungen und Ergebnisse beschrieben. Verschiedene Begriffe von höherdimensionaler Expansion, speziell Coboundary Expansion (zurückgehend auf die Arbeiten von Linial–Meshulam und Gromov) einerseits und spektrale Expansion, definiert mithilfe der Eigenwerte höherdimensionaler Laplace-Operatoren (eingeführt in den Arbeiten von Eckmann und Garland), andererseits, werden näher beschrieben und die Unterschiede zwischen den einzelnen Ansätzen werden diskutiert. Zusätzlich wird eine Auswahl aus der Vielzahl an Anwendungen von höherdimensionaler Expansion, beispielsweise das Topological Overlap Theorem von Gromov, präsentiert.
description: Expansion properties of graphs and, in particular, bounded degree expander graphs, are a central research topic in combinatorics and theoretical computer science, with many applications and connections to other areas of mathematics. In recent years, there has been a concerted effort to generalize and extend this rich and fruitful theory to higher dimensions. In this thesis, some of these recent developments and results are surveyed. Several notions of higher-dimensional expansion, in particular coboundary expansion (introduced in the work of Linial–Meshulam and Gromov) on the one hand and spectral expansion formulated in terms of the eigenvalues of higher-dimensional Laplacians (going back to the work of Eckmann and Garland) on the other hand, are described and connections and differences between these are discussed. Moreover, several applications of higher-dimensional expansion, e.g., Gromov’s topological overlap theorem are presented.

description: The aim of the study is to determine the possible use of local resources in the process of sustainable development by addressing intersectoral cooperation within partnerships of Local Action Groups (LAGs) within the environmentally valuable areas of the Lublin province. Case study was the method used in the research (13 LAGs from 30 municipalities in the areas of the highest ecological valuables in the Lublin province according to the indicator developed by D. Guzal-Dec in the study of ecological valuables of the rural and urban-rural municipalities of the Lublin province). Material was obtained from interviews with voyts/mayors of municipalities and staff of LAGs. Local development strategies (LDS) and official websites of LAGs were additional sources of information. In the light of the conducted analyzes, it must be noted that the LAG under consideration, at this stage of their functioning, are an important, but under-used instrument for the creation of local development based on local resources.

description: The aim of this study is to investigate the demographic processes as a determinant of economic activity of rural areas. Study involved the changes in the social structure of rural areas in the years 2003 and 2012, and forecasts the probable shape in 2035. The analysis focuses on population projections at regional level, providing information on the likely future size and structure of the population of rural areas in Poland. Statistical indices, which determine the level of disparities on the areas under research, were used in this analysis. The empirical data refers to NUTS 2.
Pion form factor analysis using NLO analytic perturbation theory

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: I present results for the pion's electromagnetic form factor in the spacelike region, which implement the most advanced perturbative information currently available for this observable in conjunction with a pion distribution amplitude that agrees with the CLEO data on the pion-photon transition form factor at the $1σ$ level. I show that using for the running strong coupling and its powers their analytic versions in the sense of Shirkov and Solovtsov, the obtained predictions become insensitive to the renormalization scheme and scale setting adopted. Joining the hard contribution with the soft part on account of local duality and respecting the Ward identity at $Q^2=0$, the agreement with the available experimental data, including expectations from planned experiments at JLab, is remarkable both in trend and magnitude. I also comment on Sudakov resummation within the analytic approach.

Critical percolation in the ordering kinetics of twisted nematic phases

description: I report on the experimental confirmation that critical percolation statistics underlie the ordering kinetics of twisted nematic phases in the Allen-Cahn universality class. Soon after the ordering starts from a homogeneous disordered phase and proceeds towards a broken $\mathbb{Z}_2$-symmetry phase, the system seems to be attracted to the random percolation fixed point at a special timescale $t_{\textrm{p}}$. At this time, exact formulae for crossing probabilities in percolation theory agree with the corresponding probabilities in the experimental data. The ensuing evolution for the number density of hull-enclosed areas is described by an exact expression derived from a percolation model endowed with curvature-driven interface motion. Scaling relation for hull-enclosed areas versus perimeters reveals that the fractal percolation geometry is progressively morphed into a regular geometry up to the order of the classical coarsening length. In view of its universality and experimental possibilities, the study opens a path for exploring percolation keystones in the realm of nonequilibrium, phase-ordering systems.

description: The paper presents research results of diversification in cigarettes consumption in Poland, including the division into voivodships and class of city size. Trends of changes in cigarettes consumption between 2000 to 2013 were also identified. The research was based on the results of public research panel Social Diagnosis. The results largely confirmed the results of previous studies based on the results of Household Budget Survey. The only significant differences were a lower level of cigarettes consumption in Łódzkie, Opolskie and Pomorskie voivodships and higher level in cities with less than 20 thousand inhabitants.
