description: The article raises the issue of dependence between agricultural land prices in the European Union countries. The aim of the article is to provide an answer to the following question: if the level of agricultural land price differentiation in the European Union is diminishing. The analysis covered prices of agricultural land in selected the EU countries in the period 2006 - 2016. The study was based on the occurrence of convergence in three dimensions: throughout the European Union, between the so-called old EU and between the so-called new EU countries. As a result of the conducted analyses, the phenomenon of sigma-convergence of agricultural land prices across the EU was confirmed. It was also found that in the so-called new EU countries and in so-called old EU countries there is no sigma convergence of agricultural land prices. / Synopsis. W artykule poruszono problematykę zależności pomiędzy cenami ziemi rolniczej w państwach Unii Europejskiej. Celem artykułu jest próba uzyskania odpowiedzi na pytanie czy ma miejsce zmniejszanie się zróżnicowania poziomu cen gruntów rolnych w krajach Unii Europejskiej. Analizie poddano ceny gruntów rolnych w wybranych państwach UE w latach 2006 – 2016. Badaniu poddano występowanie konwergencji w trzech wymiarach: w całej Unii Europejskiej, pomiędzy państwami tzw. starej Unii oraz pomiędzy tzw. nowymi krajami UE. W wyniku przeprowadzonych analiz potwierdzono występowanie zjawiska sigma-konwergencji cen gruntów rolnych w całej UE. Stwierdzono również, że w tzw. nowych państwach UE oraz pomiędzy państwami należącymi do tzw. starych państw UE nie zachodzi zjawisko sigma-konwergencji cen gruntów rolnych.

description: Astrophysical molecular spectroscopy is an important method of searching for new physics through probing the variation of the proton-to-electron mass ratio, $μ$, with existing constraints limiting variation to a fractional change of less than 10$^{-17}$/year. To improve on this constraint and therefore provide better guidance to theories of new physics, new molecular probes will be useful. These probes must have spectral transitions that are observable astrophysically and have different sensitivities to variation in the proton-to-electron mass ratio. Here, we concisely detail how astrophysical observations constrain the set of potential molecular probes and promising sensitive transitions based on how the frequency and intensity of these transitions align with available telescopes and observational constraints. Our detailed investigation focuses on rovibronic transitions in astrophysical diatomic molecules, using the spectroscopic models of 11 diatomics to identify sensitive transitions and probe how they generally arise in real complex molecules with many electronic states and fine structure. While none of the 11 diatomics investigated have sensitive transitions likely to be astrophysically observable, we have found that at high temperatures (1000 K) five of these diatomics have a significant number of low intensity sensitive transitions arising from an accidental near-degeneracy between vibrational levels in the ground and excited electronic state. This insight enables screening of all astrophysical diatomics as potential probes of proton-to-electron mass variation, with CN, CP, SiN and SiC being the most promising candidates for further investigation for sensitivity in rovibronic transitions.

description: The creation of an effective and efficient agricultural policy by the state is an extremely difficult task. It seems that designing proper agricultural policy becomes more difficult the larger the area. The aim of the article is to try to answer the question of what role in the creation and implementation of agricultural policy in the EU should be played by the European Commission, and by individual Member States. The answer to this question is based on the theories of fiscal and environmental federalism. The article is based on a review of literature and analysis of the optimal scope of public administration's competences in the creation and implementation of agricultural policy. The obtained results allow to determine how to optimize the division of tasks related to the agricultural policy between the levels of administration, which enables the implementation of a more effective and more efficient agricultural policy. / Synopsis. Stworzenie przez państwo skutecznej i efektywnej polityki rolnej jest niezmiernie trudnym zadaniem.

Odpowiedź na to pytanie bazuje na osiągnięciach teorii federalizmu fiskalnego i federalizmu środowiskowego. Artykuł opiera się na przeglądzie literatury oraz analizie optymalnego z punktu widzenia celów polityki rolnej zakresu kompetencji administracji publicznej w tworzeniu i wdrażaniu polityki rolnej przy uwzględnieniu aktualnych wyzwań stojących przed rolnictwem. Uzyskane wyniki pozwalają określić, jak zoptymalizować podział zadań związanych z polityką rolną między szczeblami administracji, co umożliwia wdrażanie skuteczniejszej i efektywniejszej polityki rolnej.

description: Spin dependent recombination in GaAsN offers many interesting possibilities in the design of spintronic devices mostly due to its astounding capability to reach conduction band electron spin polarizations close to 100% at room temperature. The mechanism behind the spin selective capture of electrons in Ga$^{2+}$ paramagnetic centers is revisited in this paper to address inconsistencies common to most previously presented models. Primarily, these errors manifest themselves as major disagreements with the experimental observations of two key characteristics of this phenomenon: the effective Overhauser-like magnetic field and the width of the photoluminescence Lorentzian-like curves as a function of the illumination power. These features are not only essential to understand the spin dependent recombination in GaAsN, but are also key to the design of novel spintronic devices. Here we demonstrate that the particular structure of the electron capture expressions introduces spurious electron-nucleus correlations that artificially alter the balance between the hyperfine and the Zeeman contributions. This imbalance strongly distorts the effective magnetic field and width characteristics. In this work we propose an alternative recombination mechanism that preserves the electron-nucleus correlations and, at the same time, keeps the essential properties of the spin selective capture of electrons. This mechanism yields a significant improvement to the agreement between experimental and theoretical results. In particular, our model gives results in very good accord with the experimental effective Overhauser-like magnetic field and width data, and with the degree of circular polarization under oblique magnetic fields.

description: Superconducting single crystal samples of Na_xCoO_2 + yH_2O have been produced using an electrochemical technique which dispenses with the usual bromine chemical de-intercalation step and permits much more precise control of the Na content. After careful hydration, nearly single-phase crystals have been obtained in which over 90% of the sample's volume corresponds to the superconducting Na_{0.3}CoO_2 + 1.3H_2O structure. Susceptibility and specific heat measurements confirm that bulk superconductivity has been achieved. The extracted normal state density of states indicates Fermi-liquid behavior with strong mass enhancement and a modest Wilson ratio. Measurements of H_{c2} for H||c and H||ab reveal significant anisotropy. The estimated value of H_{c2} for H||c yields a coherence length of ~100 A, consistent with an extremely narrow bandwidth.

A Possible Proof Of The Riemann Hypothesis

Subjects: Riemann Hypothesis
Asymptotic Analysis

description: In this paper, I present my approach to the Riemann Hypothesis, which potentially provides elements for a proof of it.

I start by simplifying the equality Eta(s)=0 (which is implied by the nullness of the continued Zeta(s)) by expressing |Eta(s)|^2=0 as Re(Eta(s))^2 + Im(Eta(s))^2 = 0, expressed with cosine and sine functions, then I use trigonometric identities to further break down the sum into a sum of squares purely relying on Re(s) and a double sum relying on both Re(s) and Im(s).

Using the bounded nature of the cosine function, I reformulate the equality as a problem of quadratic equations, to get rid of the dependence on Im(s) as well as the oscillations it induces,

I then consider Re(s) as a map a[n] = Re(s[n]) (n being the number of terms in Zeta(s) or Eta(s)), rather than a fixed value (since we deal with infinity),

It has already been proved that for all the nontrivial zeros, their real part is in ]0,1[,

So, I then use integrals and asymptotic analysis to observe three cases of asymptotic behaviours:

                       I MORE OR LESS FINISHED THE CHANGES

when a[n] converges to a real number in ]0,1/2[

when a[n] converges to a real number in ]1/2,1[

when a[n] converges to 1/2 (where we distinguish some more cases)

Then I conclude that the only logically consistent case is when a[n] converges to 1/2.Or maybe not, but good attempt, I guess.

IMPORTANT NOTE: I rushed to complete the last part with the corrections terms, I'll get into better detail when I have time. I did some typo corrections in this version, I'll keep making things more explicit.

For this version of the document I'll use the correction terms only in the comparison parts and not in the integral expressions, I'll do it in the coming versions.

I'm really sorry for the way it's obvious the last part is rushed and should be presented better, it's just because a lack of time.

I'll update it whenever possible

Edit: There are little mistakes, I keep correcting them, I'm sorry, the reasoning is there though.

There's a mistake here as well sorry

description: The structure of classical spinning particle based on the Kerr-Newman black hole (BH) solution is investigated. For large angular momentum, $|a|>>m$, the BH horizons disappear exposing a naked ringlike source which is a circular relativistic string. It was shown recently that electromagnetic excitations of this string lead to the appearance of an extra axial stringy system which consists of two half-infinite strings of opposite chirality. In this paper we consider the relation of this stringy system to the Dirac equation. We also show that the axial strings are the Witten superconducting strings and describe their structure by the Higgs field model where the Higgs condensate is used to regularize axial singularity. We argue that this axial stringy system may play the role of a classical carrier of the wave function.

description: We studied chromospheric oscillations using Atacama Large millimeter and sub-millimeter Array (ALMA) time-series of interferometric observations of the quiet Sun obtained at 3 mm with a 2-s cadence and a spatial resolution of a few arcsec. The same analysis, over the same fields of view and for the same intervals, was performed for simultaneous Atmospheric Imaging Assembly (AIA) image sequences in 1600 A. Spatially-resolved chromospheric oscillations at 3 mm, with frequencies of $ 4.2 +- 1.7$ mHz are observed in the quiet Sun, in both cell and network. The coherence length-scale of the oscillations is commensurate with the spatial resolution of our ALMA observations. Brightness-temperature fluctuations in individual pixels could reach up to a few hundred K, while the spatially averaged power spectral densities yield rms in the range ~ 55-75 K, i.e., up to ~ 1 % of the averaged brightness temperatures and exhibit a moderate increase towards the limb. For AIA 1600 A, the oscillation frequency is 3.7 +- 1.7 mHz. The relative rms is up to 6 % of the background intensity, with a weak increase towards disk center (cell, average). ALMA 3 mm time-series lag AIA 1600 A by ~ 100 s, which corresponds to a formation-height difference of ~ 1200 km. The ALMA oscillations that we detected exhibit higher amplitudes than those derived from the lower (~ 10 arcsec) resolution observations at 3.5 mm by White et al. (2006). Chromospheric oscillations are, therefore, not fully resolved at the length-scale of the chromospheric network, and possibly not even at the spatial resolution of our ALMA observations. Any study of transient brightenings in the mm-domain should take into account the oscillations.

description: The research presents the analysis of relations between financial sustainability and value of joint-stock companies from food industry in Central and Eastern Europe. Increase of volume of assets, shareholders’ equity and revenues demonstrated an improvement of financial sustainability and resulted in growing valuations of companies in the study period. Sample business entities achieved relatively high liquidity and profitability that proved their financial sustainability in terms of risk and return. At the same time rising operating profit margins and liquidity ratios determined higher enterprise value of joint-stock companies. This emphasized a positive relation between enterprise value and financial sustainability. Joint-stock companies demonstrated a robust capital structure with a minor decrease of corporate debt in 2011-2015. However changes in sources of financing could provoke a trade-off between financial sustainability and enterprise value. According to a regression model factors positively influencing enterprise value included revenue, cash and cash equivalents, operating profit, current liabilities and shareholder’s equity. Stimulating revenue and increasing operating profit as well as maintaining higher cash balances improves financial sustainability while debt extension can significantly deteriorate continuity of business.

description: Although recent experiments and theories have shown a variety of exotic transport properties of non-equilibrium quasiparticles (QPs) in superconductor (SC)-based devices with either Zeeman or exchange spin-splitting, how QP interplays with magnon spin currents remains elusive. Here, using non-local magnon spin-transport devices where a singlet SC (Nb) on top of a ferrimagnetic insulator (Y3Fe5O12) serves as a magnon spin detector, we demonstrate that the conversion efficiency of magnon spin to QP charge via inverse spin-Hall effect (iSHE) in such an exchange-spin-split SC can be greatly enhanced by up to 3 orders of magnitude compared with that in the normal state, particularly when its interface superconducting gap matches the magnon spin accumulation. Through systematic measurements with varying the current density and SC thickness, we identify that superconducting coherence peaks and exchange spin-splitting of the QP density-of-states, yielding a larger spin excitation while retaining a modest QP charge-imbalance relaxation, are responsible for the giant QP iSHE. The latter exchange-field-modified QP relaxation is experimentally proved by spatially resolved measurements with varying the separation of electrical contacts on the spin-split Nb.

description: A periodically kicked ring of a Bose-Einstein condensate is considered as a nonlinear generalization of the quantum kicked rotor. For weak interactions between atoms, periodic motion (anti-resonance) becomes quasiperiodic (quantum beating) but remains stable. There exists a critical strength of interactions beyond which quasiperiodic motion becomes chaotic, resulting in an instability of the condensate manifested by exponential growth in the number of noncondensed atoms. Similar behavior is observed for dynamically localized states (essentially quasiperiodic motions), where stability remains for weak interactions but is destroyed by strong interactions.

description: This article combines the literature on authoritarian regime survival with that on small states to propose a new explanation for the survival and breakdown of authoritarian monarchies. To develop the conjecture that monarchy tends to survive in small countries into a theoretically and empirically sound argument, I follow the process of iterative induction. I first inspect all authoritarian monarchies between 1946 and 2018 and find that countries with monarchic survival have a significantly smaller population size than countries where monarchy broke down. Second, I develop a theoretical explanation for this relation: the feeling of vulnerability, the social proximity, and institutional centralization, which are all typically ascribed to small countries, facilitate the stability of monarchic regimes. I conceptualize this stability with Gerschewski’s model of three pillars of authoritarian stability, co-optation, repression and legitimation; and I argue that smallness enhances each of these three via several channels. Third, to illustrate the plausibility of this explanation I compare two most likely historical cases of monarchies with diverging outcomes: Jordan and Egypt. Fourth, I inspect deviant cases, particularly Bhutan, Maldives and Tonga, to refine and finalize the argument. The main finding is that smallness prevented the violent breakdown of monarchic regimes since 1946.
Statistical fluctuations of pumping and rectification currents in quantum dots

description: We investigate the statistical fluctuations of currents in chaotic quantum dots induced by pumping and rectification at finite temperature and in the presence of dephasing. In open quantum dots, dc currents can be generated by the action of two equal-frequency ac gate voltages. The adiabatic regime occurs when the driving frequency is smaller than the electron inverse dwell time. Using numerical simulations complemented by semiclassical calculations, we consider both limits of small and large number of propagating channels in the leads when time-reversal symmetry is fully broken. We find that at intermediate temperature regimes, namely, $k_BT \alt Δ$, where $Δ$ is the mean single-particle level spacing, thermal smearing suppresses the current amplitude more effectively than dephasing. Motivated by recent theoretical and experimental works, we also study the statistics of rectified currents in the presence of a parallel, Zeeman splitting, magnetic field.

description: We present and describe an exact solution of Einstein's equations which represents a snapping cosmic string in a vacuum background with a cosmological constant $Λ$. The snapping of the string generates an impulsive spherical gravitational wave which is a particular member of a known family of such waves. The global solution for all values of $Λ$ is presented in various metric forms and interpreted geometrically. It is shown to represent the limit of a family of sandwich type N Robinson-Trautman waves. It is also derived as a limit of the C-metric with $Λ$, in which the acceleration of the pair of black holes becomes unbounded while their masses are scaled to zero.

I start by simplifying the equality Eta(s)=0 (which is implied by the nullness of the continued Zeta(s)) by expressing |Eta(s)|^2=0 as Re(Eta(s))^2 + Im(Eta(s))^2 = 0, expressed with cosine and sine functions, then I use trigonometric identities to further break down the sum into a sum of squares purely relying on Re(s) and a double sum relying on both Re(s) and Im(s).

Using the bounded nature of the cosine function, I reformulate the equality as a problem of quadratic equations, to get rid of the dependence on Im(s) as well as the oscillations it induces,

I then consider Re(s) as a map a[n] = Re(s[n]) (n being the number of terms in Zeta(s) or Eta(s)), rather than a fixed value (since we deal with infinity),

It has already been proved that for all the nontrivial zeros, their real part is in ]0,1[,

So, I then use integrals and asymptotic analysis to observe three cases of asymptotic behaviours:

                       Almost finished

when a[n] converges to a real number in ]0,1/2[

when a[n] converges to a real number in ]1/2,1[

when a[n] converges to 1/2 (where we distinguish some more cases)

Then I conclude that the only logically consistent case is when a[n] converges to 1/2.

IMPORTANT NOTE: I keep making things more explicit, so don't be surprised if a make frequent new versions.

I am currently deploying tremendous efforts to correct sentences and expressions, to make the paper smooth to read,

As you can see, the amount of signs and calculations makes the careless mistakes really easy.

I had figured out the wrong Epsilon again in the 1/2 case, I fine tuned it and corrected it now.

I make corrections and update this paper whenever possible to make things clearer

description: The paper presents the definition of innovation, advancement and development of the Fintech sector on the global scale, with particular emphasis put on Poland. Fintechs, i.e. IT companies that provide increasingly more modern solutions for customers active on the financial markets are not fully described in the literature on the subject. The aim of the paper was to present a comprehensive definition of Fintech, show the scale of this type of ventures around the world and in Poland, and analyze the forms and potential of the cooperation of Fintech companies with financial services entities, in particular with the banks. The article uses a critical analysis of the literature of mainly English-language studies from the last 5 years, indicating the state of financial innovations and their importance on the global scale. The author analyzed statistical data from PWC Global Fintech Report, CitiGPS reports, Capgemini reports and KPMG, which enabled her to present the value of global investments in Fintech. The performed cause and effect analysis indicates that investments in the Fintech sector are becoming more and more popular, that this market will be growing due to cooperation, among others, with the banks which want to meet the requirements of their customers using more advanced technologies.

description: This study was conducted to determine apparent total tract digestibility (ATTD) of phosphorus (P) and metabolisable energy (ME) concentrations for pigs of 32 different genotypes (n = 8 per grain species) of barley, rye, triticale and wheat. All genotypes were grown at the same location under the same field conditions and were fed to growing castrated crossbred pigs (initial body weight: 31.1 ± 6.95 kg) using a series of duplicate 3 × 3 Latin square designs. A basal ration, which was deficient in P, and 32 experimental rations containing 400 g/kg DM of the basal ration and 600 g/kg DM of the corresponding cereal grain were mixed. Pigs were kept in metabolism crates and the total collection method was used for separate faeces and urine collections with 7-d adaptation and 7-d collection periods. The mean ATTD of P was greater (p p p p

description: Possible correlations of the global polarization of $Λ$ hyperons with the angular momentum and transverse flow in the central region of colliding nuclei are studied based on refined estimate of the global polarization. Simulations of Au+Au collisions at collision energies $\sqrt{s_{NN}}=$ 6-40 GeV are performed within the model of the three-fluid dynamics. Within the crossover and first-order-phase-transition scenarios this refined estimate quite satisfactorily reproduces the experimental STAR data. Hadronic scenario fails at high collision energies, $\sqrt{s_{NN}}>$ 10 GeV, and even predicts opposite sign of the global polarization. It is found that the global polarization correlates with neither the angular momentum accumulated in the central region nor with directed and elliptic flow. At the same time we observed correlation between the angular momentum and directed flow in both their time and collision-energy dependence. These results suggest that, although initially the angular momentum is the driving force for the vortex generation, later the angular momentum and vortex motion become decorrelated in the midrapidity region. Then the midrapidity angular momentum is determined by the pattern of the directed flow and even becomes negative when the antiflow occurs. At the freeze-out stage, the dominant part of the participant angular momentum is accumulated in the fragmentation regions.

Then I conclude that the only logically consistent case is when a[n] converges to 1/2.

IMPORTANT NOTE:

When I rigorously checked my last part with the infinite order of expansion in the 1/2 case, I figured out that the conditions to get the right rate of convergence are actually very loose.

I keep making things more explicit, so don't be surprised if I keep making new versions.

I am still deploying tremendous efforts to correct sentences and expressions and little mistakes here and there, and to remove ambiguities. My goal is to get as accurate as possible, I still have some changes to make, I'm not far from the final version.

As you can see, the amount of signs and calculations makes the careless mistakes really easy (I've corrected a good amount up to now).

description: We construct backreacted D3/D7 supergravity backgrounds which are dual to four-dimensional N=1 and N=2 supersymmetric Yang-Mills at large N_c with flavor quarks in the fundamental representation of SU(N_c). We take into account the backreaction of D7-branes on either AdS(5) x S(5) or AdS(5) x T^{1,1}, or more generically on backgrounds where the space transverse to the D3-branes is Kaehler. The construction of the backreacted geometry splits into two stages. First we determine the modification of the six-dimensional space transverse to the D3 due to the D7, and then we compute the warp factor due to the D3. The N=2 background corresponds to placing a single stack of N_f D7-branes in AdS(5) x S(5). Here the Kaehler potential is known exactly, while the warp factor is obtained in certain limits as a perturbative expansion. By placing another D7'probe in the backreacted D3/D7 background, we derive the effect of the D7-branes on the spectrum of the scalar fluctuations to first order in N_f. The two systems with N=1 supersymmetry that we discuss are D3/D7/D7' and D3/D7 on the conifold. In both cases, the Kaehler potential is obtained perturbatively in the number of D7-branes. We provide all the ingredients necessary for the computation of each term in the expansion, and in each case give the first few terms explicitly. Finally, we comment on some aspects of the dual gauge theories.

description: “Activator regenerated by electron transfer” “atom transfer radical polymerization” (ARGET ATRP) process catalyzed by CuCl2/tris(2-pyridylmethyl)amine (TPMA) (1/1) in ethyl acetate/ethanol (EtOAc/EtOH) for the polymerization of styrene from ethyl 2,2-dichloropropanoate (EDCP) is described. The (re)generation of the activating CuI complex is accomplished by Na2CO3 without the addition of any explicit reducing agent. Differently from the analogous process operating in the presence of ascorbic acid/carbonate as the reducing system, branching is not present and control over polymerization is improved. The activation mechanism should follow a composite route, where both EtOH and TPMA contribute to the regeneration of the catalyst. The oxidation of TPMA is suggested by the absence of the ligand in the final reaction mixture and by the reduction of CuII even in t-BuOAc/t-BuOH, notwithstanding the very poor ability of t-BuOH as a reducing agent. Oxidative degradation of TPMA causes a progressive malfunctioning of the redox catalyst. Consequently, the polymerization rate, after a prompt start, becomes slower and slower, fixing conversions at around 50% (4.5 h). This means a gradual decrease of the free radical concentration, which develops unfavorable conditions for the reductive coupling (termination) between the bifunctional growing chains, preserving a controlled growth of the polymer.
