description: In the paper the production of milk in Poland and factors shaping it was analyzed against the background of the EU. The analysis shows that milk production in Poland after EU accession increased. The reasons for this phenomenon should be seen in the changes that took place in the milk market and were related to European integration, the quota system and adaptation to EU standards in the field of animal welfare. The tabular, graphical and descriptive methods were used in the analysis of the results. A statistical analysis which was carried out in the work, shows that the Euro-PLN exchange rate is the main determining factor in milk production in Poland. / Synopsis. W pracy analizie poddano produkcję mleka w Polsce oraz czynniki ją determinujące na tle UE. Z analiz wynika, że produkcja mleka w Polsce po akcesji do UE wzrosła. Przyczyn tego zjawiska należy upatrywać w zmianach, jakie zaszły na rynku mleka i związane były z integracją europejską, systemem kwotowania i dostosowaniu do standardów unijnych w zakresie dobrostanu zwierząt. W analizie wyników badań wykorzystano metody tabelaryczne, graficzne i opisowe. W pracy przeprowadzono analizę statystyczną, z której wynika, że głównym czynnikiem decydującym o produkcji mleka w Polsce jest kurs euro-złoty.

description: The Laser Interferometer Space Antenna (LISA) is expected to detect close white dwarf binaries (CWDBs) through their gravitational radiation. Around 3000 binaries will be spectrally resolved at frequencies > 3 mHz, and their positions on the sky will be determined to an accuracy ranging from a few tens of arcminutes to a degree or more. Due to the small binary separation, the optical light curves of >~ 30% of these CWDBs are expected to show eclipses, giving a unique signature for identification in follow-up studies of the LISA error boxes. While the precise optical location improves binary parameter determination with LISA data, the optical light curve captures additional physics of the binary, including the individual sizes of the stars in terms of the orbital separation. To optically identify a substantial fraction of CWDBs and thus localize them very accurately, a rapid monitoring campaign is required, capable of imaging a square degree or more in a reasonable time, at intervals of 10--100 seconds, to magnitudes between 20 and 25. While the detectable fraction can be up to many tens of percent of the total resolved LISA CWDBs, the exact fraction is uncertain due to unknowns related to the white dwarf spatial distribution, and potentially interesting physics, such as induced tidal heating of the WDs due to their small orbital separation.

 Chactas raymondhansorum Sissom 2000: 305. Unjustified emendation (junior objective synonym).
 As in the former case, Sissom (2000) believed that the species name should be emended to form a plural genitive. But since the names 'Raymond' and 'Hans' refer to different persons, they cannot be combined with the suffix – orum. The original name is to be restored, at best regarded as an arbitrary construct; Chactas raymondhansorum Sissom 2000 thus becomes an objective synonym.

Elastic forward scattering in the cuprate superconducting state

description: We investigate the effect of elastic forward scattering on the ARPES spectrum of the cuprate superconductors. In the normal state, small angle scattering from out-of-plane impurities is thought to broaden the ARPES spectral response with minimal effect on the resistivity or the superconducting transition temperature $T_c$. Here we explore how such forward scattering affects the ARPES spectrum in the d-wave superconducting state. Away from the nodal direction, the one-electron impurity scattering rate is found to be suppressed as $ω$ approaches the gap edge by a cancellation between normal and anomalous scattering processes, leading to a square-root-like feature in the spectral weight as $ω$ approaches $-Δ_\k$ from below. For momenta away from the Fermi surface, our analysis suggests that a dirty optimally or overdoped system will still display a sharp but nondispersive peak which could be confused with a quasiparticle spectral feature. Only in cleaner samples should the true dispersing quasiparticle peak become visible. At the nodal point on the Fermi surface, the contribution of the anomalous scattering vanishes and the spectral weight exhibits a Lorentzian quasiparticle peak in both energy and momentum. Our analysis, including a treatment of unitary scatterers and inelastic spin fluctuation scattering, suggests explanations for the sometimes mysterious lineshapes and temperature dependences of the peak structures observed in the \BSCCO system.

description: In the Standard Model of elementary particles, quark-mixing is expressed in terms of a 3 x 3 unitary matrix V, the so called Cabibbo-Kobayashi-Maskawa (CKM) matrix. Significant unitarity checks are so far possible for the first row of this matrix. This article reviews the experimental and theoretical information on these matrix elements. On the experimental side, we find a 2.2 sigma to 2.7 sigma deviation from unitarity, which conflicts with the Standard Model.

description: This work presents an architecture that generates curiosity-driven goal-directed exploration behaviours for an image sensor of a microfarming robot. A combination of deep neural networks for offline unsupervised learning of low-dimensional features from images, and of online learning of shallow neural networks representing the inverse and forward kinematics of the system have been used. The artificial curiosity system assigns interest values to a set of pre-defined goals, and drives the exploration towards those that are expected to maximise the learning progress. We propose the integration of an episodic memory in intrinsic motivation systems to face catastrophic forgetting issues, typically experienced when performing online updates of artificial neural networks. Our results show that adopting an episodic memory system not only prevents the computational models from quickly forgetting knowledge that has been previously acquired, but also provides new avenues for modulating the balance between plasticity and stability of the models.

description: The equilibrium behaviours of affinity two-phase liquid−liquid systems composed of polyethylene glycol (PEG) 6000 + phosphate salt + water were experimentally investigated at various pH values (4.5, 6, 7.5 and 8.4) and phosphate ligand mass fractions (PEG–PO4) (0%, 25%, 50%, 75%, 100%). The binodal curves were fitted to an empirical equation and the coefficients for the different pH and ligand concentration were estimated. The experimental tie-line compositions were estimated and correlated using the Othmer–Tobias and Bancroft equations, and the parameters were evaluated. The effects of the medium pH and the ligand amount on the phase behaviour were studied. It is found that the pH increasing and ligand concentration decreasing cause an expansion of the biphasic region. The liquid–liquid equilibrium experimental data obtained were well correlated to the activity coefficients of the non-random two-liquid (NRTL) model, and the mean deviations less than 0.68% between experimental and calculated mass fractions show that the NRTL activity model has a good ability to correlate the equilibrium compositions of the present system.

description: Packaging has become a crucial process due to the paradigm shift of More than Moore. Addressing manufacturing and yield issues is a significant challenge for modern layout algorithms. We propose to use printed circuit board (PCB) placement as a benchmark for the packaging problem. A maximum-margin formulation is devised to improve the separation between nets. Our framework includes seed layout proposals, a coordinate descent-based procedure to optimize routability, and a mixed-integer linear programming method to legalize the layout. We perform an extensive study with 14 PCB designs and an open-source router. We show that the placements produced by NS-place improve routed wirelength by up to 25\%, reduce the number of vias by up to 50\%, and reduce the number of DRVs by 79\% compared to manual and wirelength-minimal placements.

 Buthacus minipectenibus Levy, Amitai & Shulov 1973: 128.
 Buthacus minipectinibus: Vachon 1974: 948. Subsequent incorrect spelling.
 Vachoniolus minipectinatus Fet & Lowe 2000: 278. Unjustified emendation (junior objective synonym)
 The species name minipectenibus (as in the original) was spelled as minipectinibus by Vachon (1974: 948). Although Fet & Lowe (2000) assumed this was a correction, there is no indication that the change was intentional, and thus is to be interpreted as a subsequent incorrect spelling. Fet & Lowe (2000) stressed that both minipectenibus and minipectinibus were mistakenly formed Latin adjectives, then explicitly proposing minipectinatus as the correct word. In fact, the name minipectenibus is neither an adjective or a noun in the nominative singular, nor a noun in genitive, as required by Art. 11.9.1, but a compound term in another case instead (dative or ablative plural). Moreover, the correct form of the plural dative/ablative of 'pecten' is not 'pectenibus' but 'pectinibus', as used by Vachon (1974). Nevertheless, improper use of Latin itself does not make a name incorrect (Art. 32.5.1). And more importantly, words forming a species­group name must be, or be treated as the mentioned adjectives or nouns (Art. 11.9.1). No matter that minipectenibus is none of the categories listed in Art. 11.9.1, the name of Levy et al. (1973) is to be accepted in its original spelling. The easiest solution is to treat it as an arbitrary combination of letters, and as such, a noun in apposition. Vachoniolus minipectinatus is therefore an unjustified emendation and a junior objective synonym of Buthacus minipectenibus.

description: We study, both theoretically and experimentally, the negative magnetoresistance (MR) of a two-dimensional (2D) electron gas in a weak transverse magnetic field $B$. The analysis is carried out in a wide range of zero-$B$ conductances $g$ (measured in units of $e^2/h$), including the range of intermediate conductances, $g\sim 1$. Interpretation of the experimental results obtained for a 2D electron gas in GaAs/In$_x$Ga$_{1-x}$As/GaAs single quantum well structures is based on the theory which takes into account terms of higher orders in $1/g$, stemming from both the interference contribution and the mutual effect of weak localization (WL) and Coulomb interaction. We demonstrate that at intermediate conductances the negative MR is described by the standard WL "digamma-functions" expression, but with a reduced prefactor $α$. We also show that at not very high $g$ the second-loop corrections dominate over the contribution of the interaction in the Cooper channel, and therefore appear to be the main source of the lowering of the prefactor, $α\simeq 1-2/πg$. We further analyze the regime of a "weak insulator", when the zero-$B$ conductance is low $g(B=0)<1$ due to the localization at low $T$, whereas the Drude conductance is high, $g_0>>1.$ In this regime, while the MR still can be fitted by the digamma-functions formula, the experimentally obtained value of the dephasing rate has nothing to do with the true one. The corresponding fitting parameter in the low-$T$ limit is determined by the localization length and may therefore saturate at $T\to 0$, even though the true dephasing rate vanishes.

description: One of the challenges of COVID times is how to do fieldwork while protecting participants and researchers. As a consequence, applying the traditional methods where the community gathers is not possible. Speaking maps or participatory maps are one of the most used methodologies to understand the territory. Since it was not possible to have large groups for applying this methodology, we created an adapted version of it, designing a family speaking map. The objective of this method is to reflect on the dynamics of the space, build trust with the people, and at the same time to gather information about water flows and resources that might be useful for landslides modeling. Below, we present the Spanish and English version of our methodology, accompanied with some photos of its application at the neighbourhood level. [Spanish] Uno de los desafíos generados por la pandemia del COVID ha sido replantear cómo hacer trabajo de campo garantizando protección a los participantes e investigadores. Hoy en día, no es posible aplicar métodos participativos tradicionales que requieren que la comunidad se reúna en grandes grupos y comparta espacios. Los mapas parlantes o mapas participativos son una de las metodologías más utilizadas para comprender el territorio, desde la experiencia del proyecto, hemos creamos una versión adaptada de este método para ser aplicada a escala familiar, evitando el riesgo de contagio. El objetivo de este insumo, es reflexionar sobre la dinámica del espacio, generar relaciones de confianza con la comunidad, y al mismo tiempo recopilar información sobre los flujos de agua y los recursos hídricos del barrio, que podrían ser útiles para la modelización de deslizamientos. A continuación, presentamos la versión en español e inglés de nuestra metodología, acompañada de algunas fotos de su aplicación en uno de los barrios con los que trabajamos.

description: Long and consistent sunspot area records are important for understanding the long-term solar activity and variability. Multiple observatories around the globe have regularly recorded sunspot areas, but such individual records only cover restricted periods of time. Furthermore, there are also systematic differences between them, so that these records need to be cross-calibrated before they can be reliably used for further studies. We produce a cross-calibrated and homogeneous record of total daily sunspot areas, both projected and corrected, covering the period between 1874 and 2019. A catalogue of calibrated individual group areas is also generated for the same period. We have compared the data from nine archives: Royal Greenwich Observatory (RGO), Kislovodsk, Pulkovo, Debrecen, Kodaikanal, Solar Optical Observing Network (SOON), Rome, Catania, and Yunnan Observatories, covering the period between 1874 and 2019. Mutual comparisons of the individual records have been employed to produce homogeneous and inter-calibrated records of daily projected and corrected areas. As in earlier studies, the basis of the composite is formed by the data from RGO. After 1976, the only datasets used are those from Kislovodsk, Pulkovo and Debrecen observatories. This choice was made based on the temporal coverage and the quality of the data. In contrast to the SOON data used in previous area composites for the post-RGO period, the properties of the data from Kislovodsk and Pulkovo are very similar to those from the RGO series. They also directly overlap the RGO data in time, which makes their cross-calibration with RGO much more reliable. We have also computed and provide the daily Photometric Sunspot Index (PSI) widely used, e.g., in empirical reconstructions of solar irradiance.

description: We observe a new type of magneto-oscillations in the photovoltage and the longitudinal resistance of a two-dimensional electron system. The oscillations are induced by microwave irradiation and are periodic in magnetic field. The period is determined by the microwave frequency, the electron density, and the distance between potential probes. The phenomenon is accounted for by coherent excitation of edge magnetoplasmons in the regions near the contacts and offers perspectives for the development of new tunable microwave and terahertz detection schemes and spectroscopic techniques.

description: In the present investigation, densities and sound velocity of ethylene glycol and propylene glycol in the methanol solutions of propyl 4-hydroxybenzoate have been measured at different temperature and p = 0.1 MPa experimental pressure. Apparent molar volume (Vϕ) and apparent molar isentropic compression (Kϕ,s) have been determined from the experimentally computed density and sound velocity data. The information about limiting apparent molar volume (Vϕ0) and limiting apparent isentropic compression (Kϕ,s0) and their respective empirical parameters such as Sv and Sk have been evaluated for each ternary mixture at working temperatures. The values of Vϕ0 were computed to enlighten the intermolecular (solute–solvent, solute–solute and solvent–solvent) interactions present in the solution mixture, and (Vϕ0) values increase with rise in the temperature for all ternary system of present work. The Kϕ,s0 shows the negative value due to pre-eminence of solute intrinsic effect over solvent intrinsic compressibility.

description: The alpha effect is known to be an indispensable energy source of the poloidal magnetic field in the sun or planet. However, the alpha effect is quenched as the magnetic field grows due to the conservation of magnetic helicity. With these conventional understanding, what indeed generates and sustains the observed poloidal magnetic field remains a mystery. To solve this contradiction between theory and real nature, we derived a semi-analytic representation of alpha and beta using large scale magnetic helicity and energy. Applying the simulation data to alpha and beta, we found that the negative beta effect is a promising substitution of the quenched alpha effect. However, since the negative beta effect contradicts the conventional dynamo theory, we derived the new beta expression referring to the field structure model. This analytic result with the field relation between velocity U and magnetic field B shows that the beta effect in the helical system is not a fixed one. Rather, it plays a variable and dynamic role in dynamo depending on the interaction between the poloidal velocity field and relative strength of the large scale magnetic field.

description: The aim of the article is to recognize the process of greening of the agriculture in Poland in terms of worldwide development tendencies and the policy of financial support under the CAP. Analyses were conducted using statistical data from the International Federation of Organic Agriculture – IFOAM, the Institute of Organic Farming Research - FIBL and the Main Inspectorate of Trade Quality of Agricultural and Food Products – GIJHARS. Analyses showed that the process of greening of the agriculture is proceeding at different speeds on individual continents, but it is in Europe that both the area of cultivation and the market for organic food products is rapidly growing. In Poland, the implemented policy of financial support has a major impact on the process of greening of the agriculture, and the success of this process depends on the market strengthening of ecological farms (increase in commodity and shortening the food supply chain) and building ecological awareness of consumers. / Synopsis. Celem artykułu jest rozpoznanie procesu ekologizacji rolnictwa w Polsce przy uwzględnieniu światowych tendencji rozwoju rolnictwa ekologicznego i realizowanej polityki wsparcia finansowego w ramach WPR. W analizach wykorzystano dane statystyczne Międzynarodowej Federacji Rolnictwa Ekologicznego - IFOAM i Instytutu Badań Rolnictwa Ekologicznego - FIBL oraz Głównego Inspektoratu Jakości Handlowej Artykułów Rolno-Spożywczych – GIJHARS. Z przeprowadzonych analiz wynika, że proces ekologizacji rolnictwa przebiega w różnym tempie na poszczególnych kontynentach, ale to właśnie w Europie wzrasta zarówno powierzchnia upraw, jak i dynamicznie rozwija się rynek ekologicznych produktów żywnościowych. W Polsce duży wpływ na proces ekologizacji rolnictwa ma realizowana polityka wsparcia finansowego, a powodzenie tego procesu zależy od umocnienia rynkowego ekologicznych gospodarstw rolnych (wzrostu towarowości i skrócenia łańcucha dostaw żywności) oraz budowania świadomości ekologicznej konsumentów.

description: A systematic analysis of trends in the development of organic products in Ukraine and Poland was carried out, which showed that the total area of certified ecological lands for the study period from 2006-2016 in Ukraine increased by 1.7 times, and in Poland from 2004-2014 it increased by 12 times. It has been established that the most significant impact on qualitative structural changes in the economic sector is adjustment to European standards that establish a favorable system of agricultural production regulation, marking and inspection of organic products. This is why Poland, while being in the European Union, has a significant advantage over Ukraine. The system of control and certification by the authorized bodies is generalized, as well as the mechanism of financial support for organic agricultural production. The necessity of using the experience of Poland with the purpose of greening agriculture and development of organic agricultural production in Ukraine is emphasized.

description: State government-mandated social distancing measures have helped to slow down the growth of the COVID-19 pandemic in the United States. Current predictive models of the development of COVID-19, especially after mitigation efforts, are largely based on extrapolating the data from other countries. Since most states enforced stay-at-home orders towards the end of March, their effect should be reflected in the death and infection counts at the end of April. Using the data available until April 25th, we investigate the change in the infection rate due to the mitigation efforts, and project death and infection counts until September, 2020, for some of the most heavily impacted states: New York, New Jersey, Michigan, Massachusetts, Illinois and Louisiana. We find that with the current mitigation efforts five of those six states reduce their reproduction number to a value less than one, stopping the exponential growth of the pandemic. We also projected different scenarios after the mitigation is relaxed. Analysis for other states can be found at https://covid19projection.org/.

description: In the 1960s, Malaysia planted oil palm on a large scale. In the 1970s, it became the world's largest producer and exporter of palm oil. To further explore the development prospects of the oil palm industry in Malaysia, this paper first introduced the development of oil palm in Malaysia, and analyzed the world's share of Malaysian oil palm harvested area, production, yield during 1980 and 2016. The results showed that the oil palm harvested area in Malaysia reached the peak value 5.23 million ha in 2013; the yield of oil palm fruit reached the peak value 98.34 million t in 2015; the yield of oil palm fruit fluctuated between 14-20 t/ha; the ratio of Malaysian oil palm yield to world oil palm production reached its peak 51.99% in 1989. Therefore, Malaysia should update the old oil palm plantation. The development of oil palm harvested area and yield has reached the peak value, it is difficult to increase the harvested area. The proportion of Malaysian oil palm industry to the world oil palm industry is constantly declining. In future, the per unit area yield of Malaysian fresh oil palm fruit is expected to reach a new peak, and fresh oil palm fruit will exceed 20 t/ha.

description: In expounding the historical conditions of "two necessities", Marx profoundly criticized the consequence of capitalist mode of production to society and ecology. Through the analysis of the capitalist relations of production, Marx systematically completed the viewpoint system about the material circulation of nature and human society, and foresaw the ecological consequences of capitalism to the world scientifically, taking ecology and mode of production as an organic whole. Since the socialism with Chinese characteristics entered into the new era, facing the serious ecological problems in the countryside in the process of modernization, the Party and the state, through the latest interpretation of the basic principles of Marxism, have creatively replaced the unsustainable poverty-alleviation policy with the targeted poverty-alleviation policy, thus making it have an important ecological orientation in the practice of poverty-alleviation in the countryside.
Exploring the holographic principle in asymptotically flat spacetimes via the BMS group

description: We explore the holographic principle in the context of asymptotically flat spacetimes. In analogy with the AdS/CFT scenario we analyse the asympotically symmetry group of this class of spacetimes, the so called Bondi-Metzner-Sachs (BMS) group. We apply the covariant entropy bound to relate bulk entropy to boundary symmetries and find a quite different picture with respect to the asymptotically AdS case. We then derive the covariant wave equations for fields carrying BMS representations to investigate the nature of the boundary degrees of freedom. We find some similarities with 't Hooft S-matrix proposal and suggest a possible mechanism to encode bulk data.
