description: One of the priority European Union objectives are activities to reduce the climate change. Its implementation requires the creation of a low carbon economy. The main instrument for this purpose is the climate and energy policy, which is based on reducing greenhouse gas emissions while ensuring energy security. In practice, the measures aimed at reducing the amount of these substances entering the air also apply to other sectors, including agriculture. The current international obligations cause that in Polish agriculture, climate change is almost imperceptible. However, the first information on the direction and scale of the activities undertaken after 2020 bid to revise this approach. The purpose of this article is to identify the main problems related to the topic of climate and energy policy of the EU, in particular regarding the Polish agriculture. The analysis was carried out on the basis of Community documents and literature.

description: We present results showing that the multiple system DENIS-P J020529.0-115925 is likely to be a triple system of brown dwarfs. The secondary of this previously known binary system shows a clear elongation on six images obtained at six different epochs. Significant residuals remain after PSF subtraction on these images, characteristic of multiplicity, and indicating that the secondary is probably a double itself. Dual-PSF fitting shows that the shape of the secondary is consistent with that of a binary system. These measurements show that the probability that DENIS-P J020529.0-115925 is a triple system is very high. The photometric and spectroscopic properties of the system are consistent with the presence of three components with spectral types L5, L8 and T0.

description: Metrology is performed in specially designed laboratories using highly precise machinery. Many institutions are no longer able to shoulder the costs of acquiring expensive equipment alone. In this thesis, a system architecture for the location-independent operation of coordinate measuring machines (CMMs) via the internet is introduced. It aims to encourage collaboration between education and research institutions that are located far apart from each other. The reference architecture presented herein can be used as a starting point for the creation of a new type of CMM remote control systems. It uses a web-application as an interface for the operator to control either physical or simulated remote laboratories. A centralized control server, consisting of an Acquisition Server (AS) component and a Laboratory Server (LS) component is able to govern multiple machines and perform complex operations and calculations. The CMM is observed via webcam at physical remote experiments and a remote access tool or embedded simulation window at simulated remote experiments. Some changes in the control mechanisms have been made compared to conventional local CMM operation with regard to the inconstant latency and less reliable command transmission via the internet. Using the prototypical implementation Manejo, it was possible to show that the control system can achieve equivalent measurement accuracy within a local network and via the internet. Furthermore, it was discovered that internet control increases the mean duration of the probing process of a measuring object. The system can be used to promote new discoveries in the field of remote metrology, like the long-term effects of using remote or simulated laboratories in metrology education on the learning outcome of students.

description: The study contains analysis of the company’s problems in relationships with clients and proposed improvements in this area. It was determined how the system of customer relationship management (CRM) is implemented to the company, how it works and what results it brings. Failure Mode and Effects Analysis (FMEA) was used taking into account the identification from the point of view of customers, employees and IT system supporting management. Research included a group of 100 clients, entrepreneurs and farmers who completed a survey questionnaire. For the diagnosis of the most important problems in relationships with customers used a brainstorming session. The CRM system is a tool to get customers, increase profits and provide the highest level of service. Implementation of this system to the company shortened the time of customer service, improving its quality. Measures that increased the competitiveness of the enterprise covered : classification of key customers (due to the type of: farm, production and its size) and delegating employees’ responsibility for their service; improvement in the flow of information within the company; organizing trainings in the growth of employees and executives’ competencies; improving relationships with suppliers and accelerating the manufacturing process; deployment of a module in the system Asseco Wapro Prestige (archiving of a trade register); standardization of commercial offers, creating electronic orders, better matching of products and services to customers’ expectations.

description: We propose a manifestly covariant canonical method of field quantization based on the classical De Donder-Weyl covariant canonical formulation of field theory. Owing to covariance, the space and time arguments of fields are treated on an equal footing. To achieve both covariance and consistency with standard noncovariant canonical quantization of fields in Minkowski spacetime, it is necessary to adopt a covariant Bohmian formulation of quantum field theory. A preferred foliation of spacetime emerges dynamically owing to a purely quantum effect. The application to a simple time-reparametrization invariant system and quantum gravity is discussed and compared with the conventional noncovariant Wheeler-DeWitt approach.

description: Among the Fe-based superconductors, Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ is unique in that its crystal structure is the simplest and the electron correlation level is the strongest, and thus it is important to investigate the doping($x$)-temperature ($T$) phase diagram of this system. However, inevitably incorporated excess Fe currently prevents the establishment of the true phase diagram. We overcome the aforementioned significant problem via developing a new annealing method termed as "Te-annealing" wherein single crystals are annealed under Te vapor. Specifically, we conducted various magnetotransport measurements on Te-annealed superconducting Fe$_{1+y}$Te$_{1-x}$Se$_{x}$. We observed that crossover from the incoherent to the coherent electronic state and opening of the pseudogap occurs at high temperatures ($\approx$ 150 K for $x$ = 0.2). This is accompanied by a more substantial pseudogap and the emergence of a phase with a multi-band nature at lower temperatures (below $\approx$ 50 K for $x$ = 0.2) before superconductivity sets in. Based on the results, the third type electronic phase diagram in Fe-based high-$T_c$ superconductors is revealed.

Together with a systematic study of size-dependence of intrinsic tunnelling, this allowed an unambiguous discrimination between artifacts of self-heating and gaps in electronic spectrum of Bi-2212 High-$T_c$ superconductor. Finally, we analyze the reliability of intrinsic tunnelling spectroscopy and discuss how it can be improved.

description: The competitiveness of food products depends on, among the efficiency of supply chain management. This requires the company to apply modern management concepts that introduce the philosophy of partnership in supply chains and the decisions made by participants in the market process. They denote such innovative activities, such as : fast rotation in the chain, effective customer service ECR, the concept of QR or reference model SCOR. These solutions are not widely used in the food chain, although their usefulness is high for products with low durability. The paper elaborates and attempt to assess the application of innovative solutions for the organization’s strategic activities of production and trade on the background analysis of the functioning of the distribution of food products. The results allowed to determine the barriers and constraints on adaptation processes of innovation in sales and trade enterprises. Defined as factors that in the current organization of the market conditions do not allow food to enter innovation.

description: In graph embedding, the connectivity information of a graph is used to represent each vertex as a point in a d-dimensional space. Unlike the original, irregular structural information, such a representation can be used for a multitude of machine learning tasks. Although the process is extremely useful in practice, it is indeed expensive and unfortunately, the graphs are becoming larger and harder to embed. Attempts at scaling up the process to larger graphs have been successful but often at a steep price in hardware requirements. We present GOSH, an approach for embedding graphs of arbitrary sizes on a single GPU with minimum constraints. GOSH utilizes a novel graph coarsening approach to compress the graph and minimize the work required for embedding, delivering high-quality embeddings at a fraction of the time compared to the state-of-the-art. In addition to this, it incorporates a decomposition schema that enables any arbitrarily large graph to be embedded using a single GPU with minimum constraints on the memory size. With these techniques, GOSH is able to embed a graph with over 65 million vertices and 1.8 billion edges in less than an hour on a single GPU and obtains a 93% AUCROC for link-prediction which can be increased to 95% by running the tool for 80 minutes.

description: Installations of solar photovoltaic systems are growing as a promising renewable alternative to generate electricity. This paper aims to compare the power generation potential of a photovoltaic solar plant installed in a Vale do Paranhana-Brazil company with the power supplied by the utility. By demonstrating the composition of the electricity tariff currently used by the company, it was possible to perform a subsequent calculation of return on investments. The plant sizing calculation possibly did not take into account the company's consumption data. This factor influences the financial performance expected by investors.

description: We present a multi-wavelength investigation of a large-scale physical system containing the W33 complex. The extended system (~50 pc x 37 pc) is selected based on the distribution of molecular gas at [29.6, 60.2] km/s and of 88 ATLASGAL 870 micron dust clumps at d ~2.6 kpc. The extended system/molecular cloud traced in the maps of 13CO and C18O emission contains several HII regions excited by OB stars (age ~0.3-1.0 Myr) and a thermally supercritical filament ("fs1", length ~17 pc). The filament, devoid of the ionized gas, shows dust temperature (T_d) of ~19 K, while the HII regions are depicted with T_d of ~21-29 K. It suggests the existence of two distinct environments in the cloud. The distribution of Class I young stellar objects (mean age ~0.44 Myr) traces the early stage of star formation (SF) toward the cloud. At least three velocity components (around 35, 45, and 53 km/s) are investigated toward the system. The analysis of 13CO and C18O reveals the spatial and velocity connections of cloud components around 35 and 53 km/s. The observed positions of previously known sources, W33 Main, W33 A and O4-7I stars, are found toward a complementary distribution of these two cloud components. The filament "fs1" and a previously known object W33 B are seen toward the overlapping areas of the clouds, where ongoing SF activity is evident. A scenario concerning the converging/colliding flows from two different velocity components appears to explain well the observed signposts of SF activities in the system.

description: Accurate measurements of solar irradiance are crucial for the planning, tests and operation of solar power plants. The measurement uncertainty caused by the calibration is the most relevant contribution to the overall uncertainty of well-maintained radiometers. Uncertainties of field pyranometers and pyrheliometers can be significantly reduced by calibrations through WRR (World Radiometric Reference) traceable reference sensors compared to indoor calibrations. This report presents the results of the three campaigns, in which new responsivities were derived for
 80 field sensors. The presentation of the results includes: Comparison of newly acquired responsivities with manufacturer responsivity Comparison of repeatedly calibrated sensors at PSA during varies calibration campaigns Solar angle dependency of pyranometers Reliability of manufacturer responsivities Influence of an automated cloud filtering system on basis of whole sky imagers (cloud cameras)

Dynamic Bi-Objective Routing of Multiple Vehicles

description: In practice, e.g. in delivery and service scenarios, Vehicle-Routing-Problems (VRPs) often imply repeated decision making on dynamic customer requests. As in classical VRPs, tours have to be planned short while the number of serviced customers has to be maximized at the same time resulting in a multi-objective problem. Beyond that, however, dynamic requests lead to the need for re-planning of not yet realized tour parts, while already realized tour parts are irreversible. In this paper we study this type of bi-objective dynamic VRP including sequential decision making and concurrent realization of decisions. We adopt a recently proposed Dynamic Evolutionary Multi-Objective Algorithm (DEMOA) for a related VRP problem and extend it to the more realistic (here considered) scenario of multiple vehicles. We empirically show that our DEMOA is competitive with a multi-vehicle offline and clairvoyant variant of the proposed DEMOA as well as with the dynamic single-vehicle approach proposed earlier.

PT-Symmetric Quantum Mechanics: A Precise and Consistent Formulation
Creators: name: Mostafazadeh, Ali
Publisher: name: arXiv
Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The physical condition that the expectation values of physical observables are real quantities is used to give a precise formulation of PT-symmetric quantum mechanics. A mathematically rigorous proof is given to establish the physical equivalence of PT-symmetric and conventional quantum mechanics. The results reported in this paper apply to arbitrary PT-symmetric Hamiltonians with a real and discrete spectrum. They hold regardless of whether the boundary conditions defining the spectrum of the Hamiltonian are given on the real line or a complex contour.

description: Diese Studie analysierte die Potentiale und Kosten von Reduktionsmaßnahmen für Ammoniak und Partikel in der Tierhaltung mit einem ökonomisch-ökologischen Betriebsmodell und deren monetären Nutzen für Gesundheit und Biodiversität mit einem integrierten Umweltbewertungsmodell. Der Nutzen von ein- und dreistufigen Abluftreinigungssystemen, Gülleinjektoren, Schleppschuh, Güllelagerabdeckungen und stickstoffangepasster Schweinefütterung übertraf deren Kosten. Bei letzterer Maßnahme stieg sogar der Deckungsbeitrag an. Bei Abluftreinigungssystemen bestehen Synergien zwischen der Reduktion von Ammoniak und Partikeln. Für Schleppschlauch, Biofilter und stickstoffangepasste Geflügelfütterung übertrafen die Kosten jedoch deren Nutzen. Diese Maßnahmen sollten nicht umgesetzt werden. Sowohl mögliche Synergien als auch Nutzenabschätzungen sollten in die Bewertung von Reduktionsmaßnahmen einfließen.

Third Dredge-up in Low Mass Stars: Solving the LMC Carbon Star Mystery

description: A long standing problem with asymptotic giant branch (AGB) star models has been their inability to produce the low-luminosity carbon stars in the Large and Small Magellanic Clouds. Dredge-up must begin earlier and extend deeper. We find this for the first time in our models of LMC metallicity. Such features are not found in our models of SMC metallicity. The fully implicit and simultaneous stellar evolution code STARS has been used to calculate the evolution of AGB stars with metallicities of Z=0.008 and Z=0.004, corresponding to the observed metallicities of the Large and Small Magellanic Clouds, respecitively. Third dredge-up occurs in stars of 1Msol and above and carbon stars were found for models between 1Msol and 3Msol. We use the detailed models as input physics for a population synthesis code and generate carbon star luminosity functions. We now find that we are able to reproduce the carbon star luminosity function of the LMC without any manipulation of our models. The SMC carbon star luminosity function still cannot be produced from our detailed models unless the minimum core mass for third dredge-up is reduced by 0.06Msol.

description: The lattice spin model, with nearest neighbor ferromagnetic exchange and long range dipolar interaction, is studied by the method of time series for observables based on cluster configurations and associated partitions, such as Shannon entropy, Hamming and Rohlin distances. Previous results based on the two peaks shape of the specific heat, suggested the existence of two possible transitions. By the analysis of the Shannon entropy we are able to prove that the first one is a true phase transition corresponding to a particular melting process of oriented domains, where colored noise is present almost independently of true fractality. The second one is not a real transition and it may be ascribed to a smooth balancing between two geometrical effects: a progressive fragmentation of the big clusters (possibly creating fractals), and the slow onset of a small clusters chaotic phase. Comparison with the nearest neighbor Ising ferromagnetic system points out a substantial difference in the cluster geometrical properties of the two models and in their critical behavior.

description: Der Markt der Nachhaltigkeits­preise befindet sich in einer Phase exponentiellen Wachstums. Vor allem in den letzten fünf Jahren wurden immer mehr Wettbewerbe und neue Preis­kategorien bestehender Wettbewerbe eingerichtet. Im Jahr 1993 begann die Ära der Nachhaltigkeitspreise mit zwei Pionieren, die vier Preiskategorien auslobten. Zwanzig Jahre später können sich Unternehmen der Ernährungswirtschaft an 24 Wettbewerben in 82 Kategorien beteiligen. Die Vergabe­institutionen müssen sich diesen wettbewerblichen und gesellschaftsorientierten Heraus­for­derungen stellen, wollen sie mit Erfolg am Markt bestehen. Deren Sicht soll in diesem Poster­beitrag vorgestellt werden.
A Micro-glitch in the Millisecond Pulsar B1821-24 in M28

description: We report on the observation of a very small glitch observed for the first time in a millisecond pulsar, PSR B1821-24 located in the globular cluster M28. Timing observations were mainly conducted with the Nancay radiotelescope (France) and confirmation comes from the 140ft radiotelescope at Green Bank and the new Green Bank Telescope data. This event is characterized by a rotation frequency step of 3 nHz, or 10^-11 in fractional frequency change along with a short duration limited to a few days or a week. A marginally significant frequency derivative step was also found. This glitch follows the main characteristics of those in the slow period pulsars, but is two orders of magnitude smaller than the smallest ever recorded. Such an event must be very rare for millisecond pulsars since no other glitches have been detected when the cumulated number of years of millisecond pulsar timing observations up to 2001 is around 500 for all these objects. However, pulsar PSR B1821-24 is one of the youngest among the old recycled ones and there is likely a correlation between age, or a related parameter, and timing noise. While this event happens on a much smaller scale, the required adjustment of the star to a new equilibrium figure as it spins down is a likely common cause for all glitches.

description: Mit dem Web 2.0 rückt die virtuelle Kundenintegration in die Neuproduktentwicklung auch verstärkt in den Fokus von Unternehmen der Lebensmittelbranche. Den Unternehmen stellt sich in diesem Zusammenhang die Frage, wie sie Konsumenten als aktive Ideenlieferanten (prosumers) für die Neuproduktentwicklung gewinnen können. Eine vielversprechende Strategie bietet hierbei die Nutzung sozialer Medien. In der Studie wurden die charakteristischen Merkmale von Neuprodukt-Ideenwettbewerben, die von Unternehmen der Ernährungsindustrie und des Lebensmitteleinzelhandels in Deutschland durchgeführt wurden, deskriptiv herausgearbeitet. Hierzu wurden die im Web kommunizierten Ideenwettbewerbe einer Inhaltsanalyse unterzogen. Ergänzende Literaturanalysen und Inhaltsanalysen von entsprechenden Blogs führten schließlich zur Aufdeckung von acht Erfolgsfaktoren dieser neuartigen Web-2.0-Innovationsstrategie.

description: Monolayer transition metal dichalcogenides (TMDs) have been in focus of current research, among others due to their remarkable exciton landscape consisting of bright and dark excitonic states. Although dark excitons are not directly visible in optical spectra, they have a large impact on exciton dynamics and hence their understanding is crucial for potential TMD-based applications. Here, we study brightening mechanisms of dark excitons via interaction with phonons and in-plane magnetic fields. We show clear signatures of momentum- and spin-dark excitons in WS$_2$, WSe$_2$ and MoS$_2$, while the photoluminescence of MoSe$_2$ is only determined by the bright exciton. In particular, we reveal the mechanism behind the brightening of states that are both spin- \textit{and} momentum-dark in MoS$_2$. Our results are in good agreement with recent experiments and contribute to a better microscopic understanding of the exciton landscape in TMDs.

description: We give a full account of the Numerical Stochastic Perturbation Theory method for Lattice Gauge Theories. Particular relevance is given to the inclusion of dynamical fermions, which turns out to be surprisingly cheap in this context. We analyse the underlying stochastic process and discuss the convergence properties. We perform some benchmark calculations and - as a byproduct - we present original results for Wilson loops and the 3-loop critical mass for Wilson fermions.
