description: Domestic supply of corn in Indonesia has not been able to meet demand satisfactorily due to demand rising faster than supply. Therefore, Indonesia has been continuously importing corn about of 10% of the total demand. To address this problem, the Indonesian government started to implement the Farmer Field School of Integrated Crop Management (ICM-FFS) program on corn production since 2009. This study aimed to assess the impact of ICM-FFS on corn productivity, comparative and competitive advantages to produce corn as well as farmer’s income. The study found that ICM-FFS program could increase corn productivity by 30.95% of non ICM-FFS farms, of which 27.94% contributed by the difference in input use, while only 3.01% contributed by technological change. ICM-FFS farms were able to increase farmer’s income by 71.03% and social welfare by 94.69% compared to non ICM-FFS farms. Through this program, Indonesia had higher comparative advantage in producing corn as an import substitute. The provision of competitive input and output markets, enhanced technical assistance to improve corn productivity and quality, and increasing attention on corn ICM-FFS development could be considered as policy directions to improve the next implementation strategies of corn production in Indonesia.

description: Integration with the European Union allowed the restructuring of the Polish fishing sector on an unprecedented scale. Thanks to EU funding, the fishing fleet was reduced and partly modernized. No new fishing vessel was entered into operation. The restructuring of the fishing fleet was carried out almost exclusively owing to EU funding. Changes in the Polish fishing fleet improved the profitability of fishing and improved the sector’s competitiveness. This was a direct result of increased individual fishing quotas and modernized fishing vessels. The process of restructuring the Polish fishing fleet has not been concluded. Rejuvenation and modernization of the fleet are indispensable. The future Sea-Fishing Fund for 2014-2020 creates conditions for continuation of the changes already initiated. This will be possible thanks to limiting the generous subsidization of fishing in favor of the market’s greater influence. / Synopsis. Integracja z Unią Europejską, umożliwiła restrukturyzację polskiego sektora rybackiego na niespotykaną do tej pory skalę. Dzięki środkom unijnym przeprowadzono redukcję floty rybackiej oraz dokonano jej częściowej modernizacji. Natomiast nie wprowadzono do eksploatacji żadnego nowego statku rybackiego, a restrukturyzacja floty rybackiej dokonała się prawie wyłącznie dzięki środkom unijnym. Zmiany w polskiej flocie rybackiej zwiększyły rentowność połowów oraz poprawiły konkurencyjność sektora. Nastąpiło to w wyniku zwiększenia indywidualnych kwot połowowych oraz unowocześnienia jednostek rybackich. Proces restrukturyzacji polskiej floty rybackiej nie został zakończony. Konieczne jest jej unowocześnienie. Przyszły Fundusz Morsko-Rybacki na lata 2014-2020, stwarza warunki do kontynuowania rozpoczętych zmian. Ma to nastąpić w wyniku ograniczenia hojnego subsydiowania rybołówstwa na rzecz większego wpływu rynku.

description: Recently a cluster Monte Carlo algorithm has been used very successfully in the two-dimensional Edwards-Anderson (EA) model. We show that this algorithm and a variant thereof can also be used successfully in models with a non-zero spin glass transition temperature. The application of such algorithms to the site-diluted EA model in three dimensions is discussed and the efficiency of the two algorithms is compared among each other and to parallel tempering. Finally, we give evidence for a spin glass transition in the three-dimensional site-diluted EA model with Gaussian couplings at a site occupation of p = 62.5 %.

description: The paper estimates the technical efficiency and the relationship between farm size and productivity efficiency. Field survey data of 461 farmers from district Pulwama of Jammu & Kashmir (India) for the year 2013-14 were used to estimate the technical efficiency by employing Non-parametric Data Envelopment Analysis. Average technical efficiency worked out to be 48%. Most of the farms were operating at low level of technical efficiency. There was also wide dispersion in technical efficiency across farm categories. Farm size and productivity efficiency relationship was found to be non-linear, with efficiency first falling and then rising with size. Large farms tend to have higher net farm income per acre and are technically efficient compared to other small farm size categories. The study further delineated the socio-economic, institutional and farm factors of technical efficiency using Two-limit Tobit Regression Model. The results showed that Occupation, Farm Experience, Household Size, Farm Size, Membership and Seed Type were found to be important determents that influence the discrepancies in technical efficiency across farm sizes. Policymakers should, therefore, foster the development of the socio-economic, institutional and farm specific factors in order to build the capacity and management skills of the farmers.

description: Evaluations with accurate ground-truth labels (AGTLs) have been widely employed to assess predictive models for artificial intelligence applications. However, in some specific fields, such as medical histopathology whole slide image analysis, it is quite usual the situation that AGTLs are difficult to be precisely defined or even do not exist. To alleviate this situation, we propose logical assessment formula (LAF) and reveal its principles for evaluations with inaccurate ground-truth labels (IAGTLs) via logical reasoning under uncertainty. From the revealed principles of LAF, we summarize the practicability of LAF: 1) LAF can be applied for evaluations with IAGTLs on a more difficult task, able to act like usual strategies for evaluations with AGTLs reasonably; 2) LAF can be applied for evaluations with IAGTLs from the logical perspective on an easier task, unable to act like usual strategies for evaluations with AGTLs confidently.

A convergence of the correlation between the size of a florist and the period of their activity have been analyzed, as well the opinions of the respondents about the level of existing demand. The study shows that a large part of the florist feel a decrease in the demand for ornamental plants in the last five years, which particularly concerns the ornamental pot plants with leaves. The decline in demand for this products is observed in both small and large florists although the latter on a smaller level. The research also shows that demand in younger shops is greater than in older. / Synopsis. Celem pracy było ukazanie zmian w popycie na kwiaty cięte i rośliny doniczkowe w opinii właścicieli lub pracowników warszawskich kwiaciarni. Przeanalizowano poziom popytu na te produkty, a także określono jak w ciągu ostatnich 5 lat zmieniło się zapotrzebowanie na nie. Zbadano także, czy istnieje zbieżność korelacyjna pomiędzy wielkością kwiaciarni oraz okresem ich funkcjonowania, a odczuciami właścicieli i pracowników tych punktów co do poziomu istniejącego popytu. Z przeprowadzonych analiz wynika, że w znacznej części kwiaciarni zaobserwowano spadek popytu na kwiaty w ciągu ostatnich 5 lat, który szczególnie dotyczy roślin doniczkowych ozdobnych z liści. Spadek popytu odczuwały zarówno kwiaciarnie małe jak i duże, chociaż te drugie w mniejszym stopniu. Biorąc natomiast pod uwagę okres prowadzenia kwiaciarni, obiekty młodsze odczuwały większy popyt na kwiaty niż te stosunkowo dłużej działające.

The ferromagnetic -metallic ground state modifies to a cluster-glass insulator beyond x=0.03. The observed suppression in the transition temperatures (39K/at.%) is the largest reported for the Mn site subtituted manganites. We argue that charge state(valence) of the substituent has a dominant role in affecting the ferromagnetic - metallic ground state of CMR manganites.

description: In this study dairy farming activities in Turkey are employed to prove that small-scale agricultural production is disappearing rapidly due to costly investment and mechanization needs. For that purpose the cost structure and the investment needs in starting a dairy farm are analyzed. The results show that the capital requirements of building a dairy farm with optimal capacity are hard to reach for small farmers unless a system of marketing and production agricultural cooperatives and/or institutions are organized.
Is there a proper figure of merit for a plasmonic structure involved in metal-enhanced fluorescence?

description: A suitability of a nanostructure for a metal-enhanced fluorescence (MEF) is usually assessed from the value of the maximal fluorescence enhancement factor, $\mathcal{F}$, which it can generate. However, $\mathcal{F}$ is an ambiguous quantity which may dramatically depend on the intrinsic quantum yield, $q_0$, of the emitter in a free space. Here we suggest $\mathcal{F}=\mathcal{F}_{q_0=1}$ taken in the limiting case of $q_0=1$ as a proper figure of merit for a plasmonic structure involved in MEF. Any other realistic $\mathcal{F}$ in the MEF regime can be recovered from $\mathcal{F}_{q_0=1}$ by a simple $1/q_0$ scaling.

description: In Italy, olive farming is one of the most interesting examples of carbon sink in agricultural soils. The olive agro-ecosystems can in fact ensure effective action in CO2 fixation encouraging the process of carbon storage on the organic matter of the soil. Starting from the assumption that a different and more “carbon oriented” management of Italian olive groves system could represent a promising way to increase the carbon stored in agricultural land, this paper explores the possibility to implement a Payment for Ecosystem Services (PES) scheme to increase the provision of carbon sink by olive groves. The analysis focuses on the definition of the sealable ecosystem service, according to the actual policy framework and on the mode of payment that could be established. Results, suggest that an output-based payment, though more environmentally efficient, could not be enough to incentivise farmers to join the PES, as the payment per hectare might be lower using this approach.

description: The aim of this article is to present the problems of cost competitiveness of Polish dairy farms and selected European countries. Comparisons were used to study IFCN and Agricultural Census 2010. As can be seen from the analysis, the majority of farms in Poland are uncompetitive in terms of cost of milk production compared to typical farms in Germany, France, Denmark and the Netherlands. The situation is slightly higher for larger farms (more than 65 cows). The weakness of Polish farms was low technical efficiency. Mainly seen in low productivity of labor and land productivity. / Synopsis.

Do porównań wykorzystano badania prowadzone w ramach IFCN oraz z Powszechnego Spisu Rolnego 2010. Jak wynika z przeprowadzonych analiz, większość gospodarstw w Polsce jest niekonkurencyjna pod względem kosztów produkcji mleka w stosunku do typowych gospodarstw z Niemiec, Francji, Danii i Holandii. Sytuacja wygląda nieco lepiej w przypadku gospodarstw dysponujących większa skalą produkcji (utrzymujących powyżej 65 krów). Słabością polskich gospodarstw jest niska efektywność techniczna. Głównie niska wydajność pracy i produkcyjność ziemi.

description: This paper extends our previous works arXiv:1802.07306 [math.NT], arXiv:1808.02382 [math.NT] on determining the spectrum, in the Berkovich sense, of ultrametric linear differential equations. Our previous works focused on equations with constant coefficients or over a field of formal power series. In this paper, we investigate the spectrum of $p$-adic differential equations at a generic point on a quasi-smooth curve. This analysis allows us to establish a significant connection between the spectrum and the spectral radii of convergence of a differential equation when considering the affine line. Furthermore, the spectrum offers a more detailed decomposition compared to Robba's decomposition based on spectral radii.

description: (Abridged) We use optical spectroscopy to investigate the disk, wind, and accretion during the 2008 ZCMa NW outburst. Over 1000 optical emission lines reveal accretion, a variable, multi-component wind, and double-peaked lines of disk origin. The variable, non-axisymmetric, accretion-powered wind has slow ($\sim $0 km s$^{-1}$), intermediate ($\sim -$100 km s$^{-1}$) and fast ($\geq -$400 km s$^{-1}$) components. The fast components are of stellar origin and disappear in quiescence, while the slow component is less variable and could be related to a disk wind. The changes in the optical depth of the lines between outburst and quiescence are consistent with increased accretion being responsible for the observed outburst. We derive an accretion rate of 10$^{-4}$ M$_\odot$/yr in outburst. The Fe I and weak Fe II lines arise from an irradiated, flared disk at $\sim$0.5-3 $\times$M$_*$/16M$_\odot$ au with asymmetric upper layers, revealing that the energy from the accretion burst is deposited at scales below 0.5 au. Some line profiles have redshifted asymmetries, but the system is unlikely sustained by magnetospheric accretion, especially in outburst. The accretion-related structures extend over several stellar radii and, like the wind, are likely non-axisymmetric. The stellar mass may be $\sim$6-8 M$_\odot$, lower than previously thought ($\sim$16 M$_\odot$). Emission line analysis is found to be a powerful tool to study the innermost regions and accretion in stars within a very large range of effective temperatures. The density ranges in the disk and accretion structures are higher than in late-type stars, but the overall behavior, including the innermost disk emission and variable wind, is very similar independently of the spectral type. Our work suggests a common outburst behavior for stars with spectral types ranging from M-type to intermediate-mass stars.

Do action-relevant properties of objects capture attention and prime action?
Creators: name: Lam, Melanie Yah-Wai
Publisher: name: University of British Columbia
Year: 2010

description: In a recent series of studies, Tucker and Ellis (Ellis & Tucker 2000; Tucker & Ellis 1998) have proposed that objects automatically prime components of potential actions that they afford. Recent work, however, suggests that perhaps some form of cognitive coding or attentional mechanism may be responsible for the orientation effect described by Tucker and Ellis (1998) (Lyons et al., 2001; Anderson et al, 2002; Phillips & Ward, 2002). The primary purpose of the experiments reported here was to further examine the orientation effect and to investigate whether attention is captured by the action-relevant properties of objects. As a means of investigating whether attention was indeed directed to the action-relevant feature of an object, we assessed eye movement behaviour during the perception of an object. In Experiment 1, we sought to perform a conceptual replication of Tucker and Ellis (1998) original experiment and attempt to replicate the orientation effect. Thus, participants made speeded judgements of the vertical orientation of a common household object that was presented in varying vertical and horizontal orientations. The results revealed an absence of eye movements which suggested that attention may not be overtly captured by the action-relevant property (the handle) of the object presented. In addition, our reaction time (RT) results did not reveal an interaction between horizontal orientation and response. In Experiment 2, we asked participants to judge the horizontal, instead of the vertical, orientation of the presented object to examine the orientation effect when horizontal orientation was actually relevant to the task. The pattern of eye movements replicated much of those found in Experiment 1. In contrast to the RT results of Experiment 1, there was a trend toward an orientation effect such that participants responded more quickly when the arrangement of the horizontal orientation overlapped with the response set. Taken together, the results of Experiment 1 and 2 suggest a potential influence for intention and the relevant stimulus dimension for task performance. In Experiment 3, we examined how intentional set of participants impacts the influence of the objects’ action-relevant features by varying the relevant stimulus dimension and stimulus-response mapping instructions. The results showed that when the horizontal orientation was the relevant dimension to identify, the handle orientation had an influence on the response hand but not when the vertical orientation was the relevant dimension. This would suggest that RT was unaffected by the orientation of the object along the task-irrelevant dimension.

description: Goetze and Woelfle (GW) wrote the conductivity in terms of a memory function M as (ine2/m)/(omega+M(omega)), where M=i/tau in the Drude limit. The analytic properties of -M are the same as those of the self-energy of a retarded Green's function. In the approximate treatment of GW, -M closely resembles a self-energy, with differences, e.g., the imaginary part is twice too large. The correct relation between -M and the self-energy is known for the electron-phonon case and is conjectured to be similar for other perturbations. When vertex corrections are ignored there is a known relation. A derivation using Matsubara temperature Green's functions is given.

description: The aim of the study was to analyze the existing regulations in the field of regional and traditional products in the new legislative requirements and demonstrate the importance of authenticity and reliability of regional and traditional foods, as well as the presentation of the factors affecting the protection of the authenticity of the food. Regional and traditional food has attracted considerable attention of both food producers and food consumers. Traditional food is an important part of the European cultural heritage. Production and sale of traditional food products can provide not only food with high nutritional value but can be an important factor in the economic development of many European regions. The existing rules on traditional and regional foods were not consistent and lacked the transparency of the EU solutions.

description: Boosting the sensitivity of solid-state gas sensors by incorporating nanostructured materials as the active sensing element can be complicated by interfacial effects. Interfaces at nanoparticles, grains, or contacts may result in non-linear current-voltage response, high electrical resistance, and ultimately, electric noise that limits the sensor read-out. Here we report the possibility to prepare nominally one atom thin, electrically continuous metals, by straightforward physical vapor deposition on the carbon zero-layer grown epitaxially on silicon carbide. With platinum as the metal, its electrical conductivity is strongly modulated when interacting with chemical analytes, due to charges being transferred to/from Pt. This, together with the scalability of the material, allows us to microfabricate chemiresistor devices for electrical read-out of chemical species with sub part-per-billion detection limits. The two-dimensional system formed by atomically-thin metals open up a route for resilient and high sensitivity chemical detection, and could be the path for designing new heterogeneous catalysts with superior activity and selectivity.

description: The nature of cosmological solutions for a homogeneous, anisotropic Universe given by a Bianchi type-I (BI) model in the presence of a Cosmological constant $Λ$ is investigated by taking into account dissipative process due to viscosity. The system in question is thoroughly studied both analytically and numerically. It is shown the viscosity, as well as the $Λ$ term exhibit essential influence on the character of the solutions. In particular a negative $Λ$ gives rise to an ever-expanding Universe, whereas, a suitable choice of initial conditions plus a positive $Λ$ can result in a singularity-free oscillatory mode of expansion. For some special cases it is possible to obtain oscillations in the exponential mode of expansion of the BI model even with a negative $Λ$, where oscillations arise by virtue of viscosity.

Learning masculinities : youth, the media, and physical education
Creators: name: Millington, Bradley James
Publisher: name: University of British Columbia
Year: 2010

description: Despite the common claim in media studies that audiences bring well-developed interpretive strategies to media texts, young people are frequently cast as passive, or unreflexive, media consumers (Miles, 2000). This discourse is especially prominent with media that normalize physically powerful masculine personas (often called hegemonic masculinities). Studies abound that describe the gendered nature of contemporary media, but surprisingly little is known about how young people perceive and ’use’ their media interpretations in their everyday lives (Messner, 2002a). Similarly, key studies have characterized physical education (PE) as a setting that is connected to the mass media in its tendency to reinforce dominant ideas about masculinity and the male body (Kirk, 2002; Kirk & Tinning, 1994), but there remains a dearth of ethnographic research that examines how PE class works to oppose andor reinforce prevailing gender ideologies that circulate in the media. With the aim of addressing these gaps in the literature, a three-month case study of three PE classes at a Vancouver-area high school was undertaken. This research examined how young males (n=36) conceptualize the hegemonic masculinities that are frequently shown in the media, and the extent to which PE either perpetuates or counteracts their media interpretations. Employing focus group, observation, and interview methods, three key findings emerged with this research: 1) that the boys understand the media in complex, often contradictory ways, but have a tendency to be critical of hegemonic masculinities; 2) that physical education, while offering the potential for various masculinities, often promotes hegemonic gender identities as ’normal’; and 3) that the participants tended to leave their critical media skills ’unused’ in PE class, and thus displayed what can best be described as context-specific masculinities. These findings lead to a discussion of why the students’ media criticisms were not reflected in their daily PE experiences. Specifically, I suggest that the constructed environment of physical education, the students’ lingering hegemonic beliefs, and their failure to recognize dominant masculinities in their ’real’ lives limited their potentially powerful media critiques. This analysis concludes with suggestions for future research, the most important of which involves continued ethnographic work with youth audiences.

This bound is optimal and matches known data structures with $O(n)$ size. In the important case of edges from a connected, planar graph, our simplistic approach yields an expected $O(n \log^*\!n)$ construction time, which improves on the construction time of known structures for vertical segment-queries. Also for connected input, a simple extension allows the TSD approach to directly answer axis-aligned window-queries in $O(k + \log n)$ expected time, where $k$ is the result size.

description: We introduce a scheme to coherently suppress second-rank tensor frequency shifts in atomic clocks, relying on the continuous rotation of an external magnetic field during the free atomic state evolution in a Ramsey sequence. The method retrieves the unperturbed frequency within a single interrogation cycle and is readily applicable to various atomic clock systems. For the frequency shift due to the electric quadrupole interaction, we experimentally demonstrate suppression by more than two orders of magnitude for the ${}^2S_{1/2} \to {}^2D_{3/2}$ transition of a single trapped ${}^{171}\text{Yb}^+$ ion. The scheme provides particular advantages in the case of the ${}^{171}\text{Yb}^+$ ${}^2S_{1/2} \to {}^2F_{7/2}$ electric octupole (E3) transition. For an improved estimate of the residual quadrupole shift for this transition, we measure the excited state electric quadrupole moments $Θ({}^2D_{3/2}) = 1.95(1)~ea_0^2$ and $Θ({}^2F_{7/2}) = -0.0297(5)~ea_0^2$ with $e$ the elementary charge and $a_0$ the Bohr radius, improving the measurement uncertainties by one order of magnitude.

description: Presents the aspect of social responsibility as an idea in the direction of sustainable development and for the sake of improving the quality of life and preservation of natural resources and values . Dynamically growing production and consumption has a more pronounced impact on the environment. There is a strong negative link between economic growth and environmental harmful effects of consumption, use of natural resources and generation of waste. One of the key elements of the partnership is also a food economy, understood as the entire food chain from raw material acquisition – agriculture, the processing industry - by packaging production, sales, consumption and waste management. For the entire food production chain action to protect the environment and natural resources should be placed in key positions in the strategies of corporate social responsibility and development of the company.
Non-LTE line formation for Si I-II-III in A-B stars and the origin of Si II emission lines in iota Her

description: A comprehensive model atom was developed for Si I-II-III using the most up-to-date atomic data available so far. Based on the non-local thermodynamic equilibrium (non-LTE = NLTE) line formation for Si I, Si II, and Si III and high-resolution observed spectra, we determined the NLTE abundances for a sample of nine unevolved A9 to B3-type stars with well determined atmospheric parameters. For each star, NLTE reduces substantially the line-to-line scatter for Si II compared with the LTE case and leads to consistent mean abundances from lines of different ionisation stages. In the hottest star of our sample, $ι$ Her, Si II is subject to overionisation that drives emission in the lines arising from the high-excitation (above 12.5 eV) doublet levels. Our NLTE calculations reproduced 10 emission lines of Si II observed in $ι$ Her. The same overionisation effect leads to greatly weakened Si II lines, which are observed in absorption in $ι$ Her. Large positive NLTE abundance corrections (up to 0.98 dex for 5055 A) were useful for achieving consistent mean abundances from lines of the two ionisation stages, Si II and Si III. It was found that the NLTE effects are overestimated for the Si II 6347, 6371 A doublet in $ι$ Her, while the new model atom works well for the cooler stars. At this stage, we failed to understand this problem. We computed for a grid of the NLTE abundance corrections for lines of Si I, Si II, and Si III in the model atmospheres with effective temperatures and surface gravities characteristic of unevolved A-B type stars.

description: $SU(2)_L$ doublet Higgs fields are unified with gauge fields in the $U(3)_s \times U(3)_w$ model of Antoniadis, Benakli and Quirós' on the orbifold $M^4 \times (T^2/Z_2)$. The effective potential for the Higgs fields (the Wilson line phases) is evaluated. The electroweak symmetry is dynamically broken to $U(1)_{EM}$ by the Hosotani mechanism. There appear light Higgs particles. There is a phase transition as the moduli parameter of the complex structure of $T^2$ is varied.

description: The paper presents results of research conducted to characterize and assess market behaviours of businesses accepting payment cards operating in rural areas and the identification of factors determining and diversifying these behaviours. The study involved 117 points of sale, operating in rural areas in Malopolska. As results from conducted analysis, 54% of the surveyed retail and services points possessed a POS terminal, whereas the other did not accept card payments. Equipping a retail point with POS terminal depends on the kind of the retail and services point and the period of the business operation on the market. Payment cards were the most frequently accepted by self-service stores, petrol stations and shops selling television, radio and domestic appliances. Almost 70% of subjects operating on the market for between 6 and 10 years had POS terminals. The main reason why the owners of shops and service points decided to accept non-cash payments by card was interest among customers. The barriers to the development of payment card acceptance network in rural areas are high commissions charged by settlement agents and the fact that rural dwellers do not have payment cards.
Application of Lagrange inversion to wall-crossing for Quot schemes on surfaces

description: Motivated by my work on enumerative invariants for Quot schemes, I related two power series obtained by two different means. One of them was computed using geometric arguments via virtual localization methods and the other one came from working with representation theoretic objects called vertex algebras. In this note, I give proof of the equality of the two power series by relying only on techniques related to Lagrange inversion. This makes my work on Quot schemes independent of the previous results in the literature and proves a new combinatorial identity.

description: We confirm the stability of Podolsky's generalized electrodynamics by constructing a series of two-parametric bounded conserved quantities which includes the canonical energy-momentum tensors. In addition, we evaluate the transition-amplitude of this higher derivative system in BV antifield formalism and obtain the desirable generalized radiation gauge condition by choosing appropriate gauge-fixing fermion. Within the framework of Lagrangian BRST cohomology, we present the constructions of consistent interactions in Podolsky's model and when concentrating on the antighost number zero part of the master action after deformation process, we get the non-Abelian extensions of the Podolsky's theory. Furthermore, we calculate the number of physical degrees of freedom in the resulting higher derivative system utilizing Dirac-Bergmann algorithm method and show that it is unchanged if the consistent interactions are included into the free theory.

description: We first consider an exactly solvable classical field model to understand the coherence properties and the density fluctuations of a one-dimensional (1D) weakly interacting degenerate Bose gas with repulsive interactions at temperatures larger than the chemical potential. In a second part, using a lattice model for the quantum field, we explain how to carefully generalize the usual Bogoliubov approach to study a degenerate and weakly interacting Bose gas in 1D, 2D or 3D in the regime of weak density fluctuations. In the last part, using the mapping to an ideal Fermi gas in second quantized formalism, we calculate and discuss physically the density fluctuations and the coherence properties of a gas of impenetrable bosons in 1D.

description: We define higher semiadditive algebraic K-theory, a variant of algebraic K-theory that takes into account higher semiadditive structure, as enjoyed for example by the $K(n)$- and $T(n)$-local categories. We prove that it satisfies a form of the redshift conjecture. Namely, that if $R$ is a ring spectrum of height $\leq n$, then its semiadditive K-theory is of height $\leq n+1$. Under further hypothesis on $R$, which are satisfied for example by the Lubin-Tate spectrum $E_n$, we show that its semiadditive algebraic K-theory is of height exactly $n+1$. Finally, we connect semiadditive K-theory to $T(n+1)$-localized K-theory, showing that they coincide for any $p$-invertible ring spectrum and for the completed Johnson-Wilson spectrum $\widehat{E(n)}$.

description: The transversely-polarized state of a proton with arbitrary momentum is not an eigenstate of transverse angular momentum operator. The latter does not commute with the QCD Hamiltonian. However, the expectation value of the transverse angular momentum in the state is well-defined and grows proportionally to the energy of the particle. The transverse spin content of the proton is analyzed in terms of the QCD angular momentum structure. In particular, we reconfirm that the generalized parton distributions $H+E$ provide transverse orbital angular momentum densities of quarks and gluons in the infinite momentum frame.
