description: A mezőgazdasági üzemek számának csökkenése, s az egy gazdaságra jutó földterület növekedése hazánkban is általános irányzat. Kérdőíves felmérésen alapuló, valamint településenkénti teljes körű statisztikai adatbázisokon Jász-Nagykun-Szolnok megye kis- és közepes gazdaságaiban részletesebben is vizsgáltuk az 1997-2002. közötti folyamatokat. A koncentráció mértékének, sajátosságainak feltárása mellett elemeztük annak pozitív és negatív hatásait is. Utóbbiak közül a mezőgazdaság további munkaerő kibocsátását külön is ki kell emelni. Ennek ellensúlyozása a tevékenységek diverzifikációjával történhetne, aminek az ezredforduló táján még csak szerény jelei voltak a megyében. A megoldást célzó intézkedések a Nemzeti Fejlesztési Terv Agrár és Vidékfejlesztési Operatív Programjában és a Nemzeti Vidékfejlesztési Tervben is megjelentek. A feladat nagyságához képest viszonylag szerény források miatt azonban nagy a valószínűsége annak, hogy ezek 2004 és 2006 között nem lesznek képesek fordulatot elérni. ------------- Dwindling number of agrarian enterprises and increases in the size of agricultural land per farm is also a general trend in this country. On basis of questionnaire surveys and detailed statistical data banks we studied the course of events concerning small and medium sized farms in each settlement of the county of Jász-Nagykun-Szolnok between 1997 and 2002 in detail. Determination of the extent and characteristics of concentration apart we analyzed their positive and negative impacts, of which further release of workforce needs to be especially emphasized. This could be compensated by the diversification of operations, although few signs of this were discemable at the turn of millennia in the county. Measures aimed at resolving these problems were present in the Agrarian and Countryside Development Operative Program of the National Development Plan and the National Countryside Development Plan. Due to the modest resources devoted to the tasks it is unlikely that these measures will bring about the desired turn-around between 2004 and 2006.

description: The 10-nm-scale structure in silicon cleavage is studied by the quantum mechanical calculations for large-scale electronic structure. The cleavage process on the order of 10 ps shows surface reconstruction and step formation. These processes are studied by analyzing electronic freedom and compared with STM experiments. The discussion presents the stability mechanism of the experimentally observed mode, the $(111)$-$(2 x 1)$ mode, beyond the traditional approach with surface energy. Moreover, in several results, the cleavage path is bent into the experimentally observed planes, owing to the relative stability among different cleavage modes. Finally, several common aspects between cleavage and other phenomena are discussed from the viewpoints of the nonequilibrium process and the 10-nm-scale structure.

description: Many-body quantum systems can exhibit a striking degree of symmetry unparalleled by their classical counterparts. While in real materials SU($N$) symmetry is an idealization, this symmetry is pristinely realized in fully controllable ultracold alkaline-earth atomic gases. Here, we study an SU($N$)-symmetric Fermi liquid of $^{87}$Sr atoms, where $N$ can be tuned to be as large as 10. In the deeply degenerate regime, we show through precise measurements of density fluctuations and expansion dynamics that the large $N$ of spin states under SU($N$) symmetry leads to pronounced interaction effects in a system with a nominally negligible interaction parameter. Accounting for these effects we demonstrate thermometry accurate to one-hundredth of the Fermi energy. We also demonstrate record speed for preparing degenerate Fermi seas, reaching $T/T_F = 0.12$ in under 3 s, enabled by the SU($N$) symmetric interactions. This, along with the introduction of a new spin polarizing method, enables operation of a 3D optical lattice clock in the band insulating-regime.

description: Este artigo pretende contribuir para a compreensão da adoção de social media marketing por empresas B2B. Tendo por base os principais contributos presentes na literatura, o estudo definiu duas questões de investigação: (i) que fatores facilitam a adoção de estratégias de social media marketing pelas empresas B2B?; (ii) de que forma o social media marketing afeta o desempenho das empresas B2B? O estudo utiliza uma metodologia exploratória qualitativa através da realização de nove entrevistas semi-estruturadas a gestores de empresas portuguesas de diferentes setores do mercado B2B, e com perfis diversos em termos de idade, número total de trabalhadores e volume de vendas. Apesar do reconhecimento unânime da importância da internet enquanto veículo essencial de informação e comunicação, os gestores que participaram neste estudo evidenciaram um certo grau de ceticismo em relação à eficácia do social media marketing nas empresas B2B. O estudo demonstra, igualmente, a dificuldade em definir os objetivos de marketing digital, muitas vezes ausentes ou demasiado genéricos para serem eficazes. Em termos gerais, o artigo oferece indicações relevantes para académicos e profissionais, incluindo as entidades que apoiam as empresas B2B nas estratégias de social media marketing.

description: A tanulmányban megvizsgáltuk, hogy miként alakult a magyar gabonatermelő gazdaságok működési versenyképessége az 1998-2002 közötti tesztüzemi adatok alapján méret, típus, földminőség és az adott üzem vezetőjének életkora szerinti csoportosításban. A működési versenyképesség becslésének alapját az egységnyi inputra jutó maximális output szerinti legjobb gyakorlat határvonalához mért rangsorolás képezi. Az OCRA-modell eredményei szerint a gabonatermelők működési versenyképességének instabil javulását figyelhetjük meg a vizsgált időszakra és üzemekre vonatkozóan. A vizsgált gabonatermelő vállalkozások esetében a nagyobb méretűeknél jobb működési versenyképesség figyelhető meg a kisebbekhez képest. A gabonatermelésre szakosodott gazdaságok jobb működési versenyképességet értek el, mint az állattenyésztésre, vagy vegyes gazdálkodásra szakosodott gabonatermelő vállalkozások. A földminőség szerinti csoportosításban az elvárt eredményt kaptuk: minél jobb minőségű termőföldön gazdálkodtak a gabonatermelők, annál kedvezőbb működési versenyképességet tudtak elérni. A 40-50 év közötti gabonatermelő döntéshozók érték el a legjobb működési versenyképességet. ----------------- On the basis of data from test-enterprises between 1998-2002 we investigated in this study the operational competitiveness o f Hungarian cereal growing farms as function o f farm size and type, quality of soil and age of manager controlling the farm. Ranking order determined against the borderline of best practices measured as maximum output per unit input constituted the basis o f the assessment o f operative competitiveness. According to the OCRA model unstable improvements in operational competitiveness o f cereal growers could be observed during the study period at the studied farms. Of the investigated enterprises bigger farms displayed higher operational competitiveness than smaller farms. Farms specializing in cereal growing achieved higher operational competitiveness than those specializing in animal husbandry or mixed operations. Quality of soil as a variable yielded the expected conclusion: the better soil farmers were working, the higher operational competitiveness they could achieve. Cereal grower managers aged between 40 to 50 years achieved the highest operational competitiveness.

description: A szarvasmarhatartó gazdaságok Magyarországon a takarmánynövények közül legnagyobb tömegben a silókukoricát alkalmazzák. A silókukorica előállítása, mozgatása költséges, ágazati elszámolása pedig számos problémát vet fel. A tanulmány egy olyan leíró jellegű szimulációs modell használatának eredményeit mutatja be, amely részletesen foglalkozik a takarmánynövény termesztésének szinte minden tényezőjével. A modell a megadott input adatok alapján érté-keli a tevékenység költségeinek szerkezetét mind költségnemenként, mind pedig elszámolhatóság szerint. Figyelembe veszi a támogatások értékeit, valamint egyes alternatív költségeket. A modell különböző nyereségigényekhez rendelt árcent-rumokat kalkulál, melyek a költségek mellett az eszközök kamatigényét is tartalmazzák. Ezen túl a 0%-os nyereségigényű változat (az elszámoló ár alapja) egyfajta érzékenységvizsgálatát is elvégzi, mely a hozamváltozás, a termőterület telephelytől való távolsága, továbbá az üzemanyag árának alakulása hatásait mutatja be. A számítások alapján megállapítható, hogy 25 t/ha-os hozam alatt a silókukorica nyereségesen nem értékesíthető, illetve a szállítási távolság, mely még nem rontja a tejtermelés eredményeit, maximum 10 km lehet. A gázolaj árának változása nincsen számottevő hatással az árcentrum alakulására. A modell alkalmazásával kimutatható, hogy a jelenlegi elszámolási gyakorlat mellett országosan több mint 1,5 milliárd Ft látens veszteség érheti a takarmánynövény-termesztési ágazatokat. ---------------- Of all fodder crops, silage maize is used in the greatest quantity on Hungarian dairy farms. The production and transportation of silage is a costly process and causes a number of problems in accounting. The current study presents the findings from the application of a descriptive, simulation model, covering in detail nearly all factors involved in fodder crop production. Based on input data, the model evaluates the structure of production costs detailing both the cost types and way of accounting, while it takes into account the value of supports and some altemative costs. The model calculates mid-prices associated with profit expectations, which include costs as well as interest rate requirements of assets. The zero-profit version may also perform a kind of sensitivity test indicating the effects of changes in yield, the distance between cultivated land and farm premises, and fluctuations in fuel price. Calculations show that silage maize production is not profitable under a yield of 25t/ha, unless the distance of transportation is less than 10km. Changes in fuel prices do not affect considerably the mid-price. Our modeling indicates that under present accounting practices farms in Hungary producing crop fodder may potentially suffer from a loss of HUF 1.5 billion every year.

description: Within the kinetic energy driven superconducting mechanism, the interplay between the single particle coherence and superconducting instability in doped cuprates is studied. The superconducting transition temperature increases with increasing doping in the underdoped regime, and reaches a maximum in the optimal doping, then decreases in the overdoped regime, however, the values of this superconducting transition temperature in the whole superconducting range are suppressed to low temperature due to the single particle coherence. Within this superconducting mechanism, we calculate the dynamical spin structure factor of cuprate superconductors, and reproduce all main features of inelastic neutron scattering experiments in the superconducting-state.

Numa fase seguinte, este estudo tem também como objetivo verificar, de uma forma mais detalhada, qual o impacto das 3 dimensões que constituem o CESBC (Consumo, Contribuição e Criação) nos 4 consequentes anteriormente referidos. Para a realização deste trabalho de investigação desenvolveu-se um questionário online que contou com a participação de 221 respondentes. A analise dos dados, realizada tendo por base o Modelo das Equações Estruturais, concluiu que o CESBC tem um impacto positivo no valor global da marca, amor a marca, lealdade a marca e no passa-palavra. Considerando as 3 dimensões que constituem o CESBC, concluiu-se ainda que as marcas terão de ter uma especial atenção aos aspetos relacionados especificamente com a dimensão consumo. Este estudo evidencia a importância do conteudo gerado nas redes sociais das marcas e aprofunda o conhecimento das consequências do CESBC. Perante estas conclusões as marcas poderão definir estratégias que melhorem, através do Facebook, o seu relacionamento com os consumidores.

description: We derive exact analytical expressions for correlation functions of singular values of the product of $M$ Ginibre matrices of size $N$ in the double scaling limit $M,N\rightarrow \infty$. The singular value statistics is described by a determinantal point process with a kernel that interpolates between GUE statistic and Dirac-delta (picket-fence) statistic. In the thermodynamic limit, $N\rightarrow \infty$, the interpolation parameter is given by the limiting quotient $a=N/M$. One of our goals is to find an explicit form of the kernel at the hard edge, in the bulk and at the soft edge for any $a$. We find that in addition to the standard scaling regimes, there is a new transitional regime which interpolates between the hard edge and the bulk. We conjecture that these results are universal, and that they apply to a broad class of products of random matrices from the Gaussian basin of attraction, including correlated matrices. We corroborate this conjecture by numerical simulations. Additionally, we show that the local spectral statistics of the considered random matrix products is identical with the local statistics of Dyson Brownian motion with the initial condition given by equidistant {positions,} with the crucial difference that this equivalence holds only locally. Finally, we have identified a mesoscopic spectral scale at the soft edge which is crucial for the unfolding of the spectrum.

A termelékenységet a termőföld és az élőmunka esetében mindenképpen növelni kell, amely a termelésben lekötött munka és föld mennyiségének csökkentésével érhető el. A munka és a termőföld költsége a jövőben mindenképpen növekedni fog, és a termelőknek a jövedelmező termelés érdekében a tényező-szerkezet optimalizálását kell a tényezőköltségek viszonylatában végrehajtani. Ennek kivitelezéséhez mindenképpen vizsgálni kell a tényezők kvalitatív tulajdonságait is, mert kizárólag számszerűsíthető információk birtokában az optimalizálást nem lehet hatékonyan végrehajtani. -------------- Our investigations indicated that the specific efficiency of Hungarian farms, their operational and land utilization efficiency lag behind that of EDF and East Germany. In cases of land and work force, efficiency needs to be increased under any circumstances that can be achieved by reducing the workforce involved in production and the quantity of cultivated land. The costs of work and arable land will increase in the future and producers in the interest of increased income need to optimize the structures and costs of various factors. To achieve the objectives the characteristics of these factors need to be studied, because optimization cannot be effectively achieved on the basis of numerical information alone

description: As reações emocionais complexas combinam e estruturam-se em duas dimensões motivacionais, traduzidas pelos estados defensivos e apetitivos, mecanismos de adaptação evolutiva e de sobrevivência. Na natureza, os seres humanos quando expostos a estímulos emocionais, produzem padrões neuronais de processamento atencional, (> 120 ms), reflectindo-se na seleção de respostas e na discriminação de estímulos. Estes padrões, modeladores de estados afetivos e cognitivos, afetam os campos recetivos neuronais, com modulação da amplitude da early posterior negativity (EPN), gerando comportamento humano atencional distinto, entre homens e mulheres, quando expostos as mesmas condições experimentais. Para aferirmos se este processo ocorre em estímulos de consumo alimentar, testamos o projetivo comportamento preferencial e diferencial de consumo, tendo por base as diferenças evolutivas dos sujeitos do sexo masculino e feminino. Sujeitamos os participantes a um procedimento experimental exploratório, induzindo um conjunto de estímulos forçados, compostos por imagens de Hambúrgueres vegetarianos e não vegetarianos. A medição da actividade cerebral, foi adquirida através de Eletroencefalografia (EEG). Os resultados sugerem que a modulação da amplitude early posterior negativity (EPN), tanto para estímulos positivos, como negativos apresentam diferenças significativas entre a actividade cerebral de género. Nos pontos de coorte entre 120 e 200 ms, foi possível observar que as regiões ocipito-temporais estiveram mais ativadas para os participantes do sexo masculino quando foram expostos a estímulos de hambúrgueres não vegetais.

Entrepreneurial Marketing: the practices of Portuguese tourism startups

Publisher: name: ICIEMC Proceedings

description: Start-ups and small businesses face significant challenges due to the increasingly complex and fast-changing markets in which they operate. As a consequence, these types of organizations must be capable of adjusting their resources and react quickly in this reality. In this case, marketing plays a key role in creating brand awareness and attracting and retaining customers. Thus, the creation and development of their marketing strategies is an ongoing debate which needs to be addressed and well understood. When combining these two fields (Start-ups and marketing), the concept of Entrepreneurial Marketing (EM) appears. Despite the debate on its definition, it is clear that EM differs from traditional marketing regarding its business strategy (which is more proactive, risk-taking and innovative), its methods (which are more informal and interactive) and its outcomes. Given the relevance to understand and discuss EM, this paper analyses tourism-related start-ups in Portugal who applied to a yearly competition in the tourism field launched by a Portuguese venture capital organization during 2016-19. The goal is to understand the marketing or EM strategies and methods used by investment ready start-ups. It was observed that start-ups usually really on short-term low-risk marketing strategies, such as the development of websites, social networks, related websites, as well as through sponsoring bloggers/influencers. Also, partnerships are used as a marketing strategy, given its effectiveness and cost-efficiency.

description: The automotive world is changing. New technologies, new driving assistance functions, autonomous driving. Electrical car seems to be the future. But are all these things really necessary if we only need to go from one point to another? Many years ago Mr. Henry Ford made a bet: to offer mobility and freedom to everybody. Is this need still valid today? When you think about modern stories of Dacia or Tata Nano, the answer may be yes. Ford Model T was replaced in our times by the affordable car, also known as the low cost car. We will present in this thesis the premises of the low cost car introduction, the low cost car market specifics as well as the most famous examples of low cost cars that are already milestones in the history of automotive industry. We will define and analyze the most influencing factors of the car buyers' decision in three different scenarios in order to find the answer to one question: is there any future for the low cost car market in a medium term? And moreover, taking into account the current changes within urban mobility sector? Until 2025 many changes will happen that will shape our mobility perspectives. Starting with the first chapter, we will take a brief look at the automotive sector in order to find out the most favorable market for the low cost and ultra-low cost cars. How affordable must be an affordable car in term of price and for which category of customers? We have already a couple of examples with models that defined the modern low cost car concept: Dacia from Renault and Nano from Tata. In the second chapter we will see their path from design to manufacturing, their specifications and we will find out if they have been successful or not. It is now time to check the future perspectives of this car segment. But how it will be the future? As it is getting harder to predict it, we will analyze the trend taking into consideration three evolution scenarios based on the so called 'megatrends' that are shaping the automotive industrys future. Each and every scenario (High Tech, Budget and Sustainable) has its own implications in the industry, starting with the markets, customers, products or business models and finishing with the business organizations and their employees. Next step would be to identify the factors that are influencing car buyers' decision in general and to define which factors have an impact on the potential low cost car customers. Finally, we will have the elements that predict the future of the segment, by combining the evolution of the most impacting factors in all three future evolution scenarios.

description: We introduce a new model of near-forward elastic proton-(anti)proton scattering at high energy based on the modern formulation of Pomeron and Odderon in terms of Wilson lines and generalized TMDs (GTMDs). We compute the helicity-dependent elastic amplitudes $ϕ_{1,2,3,4,5}$ in this model and study their energy dependence from the nonlinear small-$x$ evolution equations. While both Pomeron and Odderon contribute to helicity-flip processes in general, in the forward limit $t=0$ only the double helicity-flip amplitude $ϕ_2$, dominated by the spin-dependent Odderon, survives. This may affect the extraction of the $ρ$ parameter as well as the total cross section in the LHC energy domain and beyond.

Regulation of polymyxin B and cationic antimicrobial peptide resistance in pseudomonas aeruginosa
Creators: name: McPhee, Joseph B.
Publisher: name: University of British Columbia
Year: 2010

description: Pseudomonas aeruginosa is a Gram-negative, opportunistic pathogen that is noted for its environmental ubiquity, its metabolic potential and its intrinsic resistance to a wide variety of antimicrobials, detergents, dyes, and biocides. These properties are consequences of a large (6.3 Mb) genome containing ~5500 genes of which 9.4% encode regulatory proteins. One of the largest classes of regulators in the P. aeruginosa genome is the two-component regulators. This work describes the contribution of two two-component regulatory systems, PhoP-PhoQ and PmrA-PmrB to Mg²⁺-limitation induced polymyxin B and cationic antimicrobial peptide resistance. Both of these systems respond to limiting Mg²⁺ and cause increased transcription of an eight-gene operon, pmrHFIJKLM-ugd, that is responsible for the addition of aminoarabinose to 1 and 4' phosphates on Lipid A. In addition, the PmrA-PmrB system regulates a three gene operon, PA4773-PA4775 that also contributes to polymyxin B and cationic antimicrobial peptide resistance. In addition to regulating polymyxin B and cationic antimicrobial peptide resistance, the PhoP-PhoQ system also directly regulates several small ORFs, one of which PA0921 contributes to swimming motility via an unknown mechanism. Similarly, PmrA-PmrB regulate other phenotypes, including the growth of P. aeruginosa in the presence of Fe³⁺. This growth phenotype occurs through gene products encoded by the feoAB operon. Interestingly, all genes identified in this study that are PmrA-PmrB regulated are also regulated by the presence of sub-inhibitory concentrations of cationic antimicrobial peptides. The regulation of PA4773-PA4775 and pmrHFIJKLM-ugd via cationic peptides is mostly independent of the PmrA-PmrB and PhoP-PhoQ systems. This observation explains why adaptive resistance to cationic antimicrobial peptides occurs and suggests that another, as yet unidentified, regulator is responsible for the detection of cationic antimicrobial peptides. A third regulatory system, PxrRS, is also identified. Mutants in this system show increased susceptibility to cationic antimicrobial peptides and polymyxin B. This susceptibility was not due to loss of regulation of the PA4773-PA4775 or pmrHFIJKLM-ugd. Microarray analysis demonstrated downregulation of a number of heat-shock proteins, as well as two operons potentially involved in efflux. The combined downregulation of heat-shock proteins involved in response to cellular stress and efflux systems suggests that intrinsic cationic peptide resistance is altered in these mutants.

description: We have studied zig-zag boron nitride (BN) nanotubes doped with the Ni hexagonal-closepacked nanowire. The doped BN nanotubes are ferromagnetic metals with substantial magnetism. Some special magnetic properties resulting from the interaction between the Ni nanowire and BN nanotubes are found. The Ni doped BN(9,0) nanotube shows semi-half-metallic behavior, which could become half-metallic after doping electrons more than 1.4 e/unit cell. The intrinsic halfmetallic behavior could be achieved by two dierent ways: one is coating the Ni nanowire with a smaller BN nanotube, i.e., BN(8,0), the other is using hydrostatic pressure to homogeneously compress the Ni doped BN(9,0) nanotube.

description: We demonstrate rotational cooling of the silicon monoxide cation via optical pumping by a spectrally filtered broadband laser. Compared with diatomic hydrides, SiO\+ is more challenging to cool because of its smaller rotational interval. However, the rotational level spacing and large dipole moment of SiO\+ allows direct manipulation by microwaves, and the absence of hyperfine structure in its dominant isotopologue greatly reduces demands for pure quantum state preparation. These features make $^{28}$Si$^{16}$O\+ a good candidate for future applications such as quantum information processing. Cooling to the ground rotational state is achieved on a 100 ms time scale and attains a population of 94(3)\%, with an equivalent temperature $T=0.53(6)$ K. We also describe a novel spectral-filtering approach to cool into arbitrary rotational states and use it to demonstrate a narrow rotational population distribution ($N\pm1$) around a selected state.

description: The Feline Five Model (FFM) is a comprehensive personality model comprised of five different dimensions: Neuroticism, Extraversion, Impulsiveness, Dominance, and Agreeableness. The theory behind the model is that the placement on the continuum suggests the individual's personality. This study details how to provide a multifaceted approach to domestic cats' personality using the FFM questionnaire completed by cat owners. We used Qualtrics® to collect personality data using the Feline Five model of (n=307) domestic cats. We used the K-elbow method of selecting the optimal number of clusters by fitting the K-Means model with a range of K values. Then, we used principal components analysis to determine the potential number of factors within the data set. We demonstrated that scores on the questions presented in the Feline Five test aggregate into five distinct clusters. In summary, the final analysis yielded five different factors that depict personality in domestic pet cats from our sample.
The Method of a Two-Point Conditional Column Density for Estimating the Fractal Dimension of the Galaxy Distribution

description: We suggest a new method for estimating the fractal dimension of the spatial distribution of galaxies, the method of selected cylinders. We show the capabilities of this method by constructing a two-point conditional column density for galaxies with known redshifts from the LEDA database. The fractal dimension of a sample of LEDA and EDR SDSS galaxies has been estimated to be D = 2.1 for cylinder lengths of 200 Mpc. Amajor advantage of the suggested method is that it allows scales comparable to the catalog depth to be analyzed for galaxy surveys in the form of conical sectors and small fields in the sky.

description: We study multipartite entanglement measures for a one-dimensional Ising chain that is capable of showing both integrable and nonintegrable behaviour. This model includes the kicked transverse Ising model, which we solve exactly using the Jordan-Wigner transform, as well as nonintegrable and mixing regimes. The cluster states arise as a special case and we show that while one measure of entanglement is large, another measure can be exponentially small, while symmetrizing these states with respect to up and down spins, produces those with large entanglement content uniformly. We also calculate exactly some entanglement measures for the nontrivial but integrable case of the kicked transverse Ising model. In the nonintegrable case we begin on extensive numerical studies that shows that large multipartite entanglement is accompanied by diminishing two-body correlations, and that time averaged multipartite entanglement measures can be enhanced in nonintegrable systems.

description: The optical properties of infinite planar array of scattering particles, metasurfaces and metagratings, are attracting special attention lately for their rich phenomenology, including both plasmonic and high-refractive-index dielectric meta-atoms with a variety of electric and magnetic resonant responses. Herein we derive a coupled electric and magnetic dipole (CEMD) analytical formulation to describe the reflection and transmission of such periodic arrays, including specular and diffractive orders, valid in the spectral regimes where only dipolar multipoles are needed. Electric and/or magnetic dipoles with all three orientations arising in turn from a single or various meta-atoms per unit cell are considered. The 2D lattice Green function is rewritten in terms of a 1D (chain) version that fully converges and can be easily calculated. Modes emerging as poles of such lattice Green function can be extracted. This formulation can be applied to investigate a wealth of plasmonic, all-dielectric, and hybrid metasurfaces/metagratings of interest throughout the electromagnetic spectrum.

A large amount of research software builds on a core codebase maintained by a team of core developers (e.g CRAN packages rely on base R). The sustainability and EDI (equality, diversity and inclusion) issues we see in scientific software in general are even more acute in core development. This presentation briefly introduces an initiative to address this in the R project.

description: A semianalytical approach is developed to calculate the effective pair potential of rigid arbitrarily shaped macroions with a nonvanishing particle volume, valid within linear screening theory and the mean-field approximation. The essential ingredient for this framework is a mapping of the particle to a singular charge distribution with adjustable effective charge and shape parameters determined by the particle surface electrostatic potential. For charged spheres this method reproduces the well-known Derjaguin-Landau-Verwey-Overbeek (DLVO) potential. Further exemplary benchmarks of the method for more complicated cases, like tori, triaxial ellipsoids, and additive torus-sphere mixtures, leads to accurate closed-form integral expressions for all particle separations and orientations. The findings are relevant for determining the phase behaviour of macroions with experiments and simulations for various particle shapes.

description: In order to study the phenomenon in detail that income distribution follows Pareto law, we analyze the database of high income companies in Japan. We find a quantitative relation between the average capital of the companies and the Pareto index. The larger the average capital becomes, the smaller the Pareto index becomes. From this relation, we can possibly explain that the Pareto index of company income distribution hardly changes, while the Pareto index of personal income distribution changes sharply, from a viewpoint of capital (or means). We also find a quantitative relation between the lower bound of capital and the typical scale at which Pareto law breaks. The larger the lower bound of capital becomes, the larger the typical scale becomes. From this result, the reason there is a (no) typical scale at which Pareto law breaks in the income distribution can be understood through (no) constraint, such as the lower bound of capital or means of companies, in the financial system.
