description: Bird collisions with windows represent a growing environmental concern, as one of the leading causes of human-related bird mortality. The consequences of these collisions extend beyond the immediate loss of individual birds; they also pose a threat to overall biodiversity and ecosystem health. To address this issue, our engineering capstone project aims to develop a comprehensive system that detects bird collisions while also calculating the heat flow rate of windows. This project builds upon the past capstone project design that performs the bird collision detection using an accelerometer and Arduino. The motivations behind this project stem from the need to better understand and mitigate bird collisions, as well as to improve the energy efficiency of buildings. By providing researchers and building managers with valuable data on the frequency and circumstances of bird collisions, we aim to contribute to the development of targeted strategies and solutions that can reduce bird mortality rates and protect biodiversity. Additionally, by analyzing the energy efficiency of windows via heat flow rate, our project can inform decisions about building design and materials, potentially leading to more energy-efficient and environmentally friendly construction practices.

description: The Team Orienteering Problem (TOP) is an NP-hard routing problem in which a fleet of identical vehicles aims at collecting rewards (prizes) available at given locations, while satisfying restrictions on the travel times. In TOP, each location can be visited by at most one vehicle, and the goal is to maximize the total sum of rewards collected by the vehicles within a given time limit. In this paper, we propose a generalization of TOP, namely the Steiner Team Orienteering Problem (STOP). In STOP, we provide, additionally, a subset of mandatory locations. In this sense, STOP also aims at maximizing the total sum of rewards collected within the time limit, but, now, every mandatory location must be visited. In this work, we propose a new commodity-based formulation for STOP and use it within a cutting-plane scheme. The algorithm benefits from the compactness and strength of the proposed formulation and works by separating three families of valid inequalities, which consist of some general connectivity constraints, classical lifted cover inequalities based on dual bounds and a class of conflict cuts. To our knowledge, the last class of inequalities is also introduced in this work. A state-of-the-art branch-and-cut algorithm from the literature of TOP is adapted to STOP and used as baseline to evaluate the performance of the cutting-plane. Extensive computational experiments show the competitiveness of the new algorithm while solving several STOP and TOP instances. In particular, it is able to solve, in total, 14 more TOP instances than any other previous exact algorithm and finds eight new optimality certificates. With respect to the new STOP instances introduced in this work, our algorithm solves 30 more instances than the baseline.

description: The kinetic theory of evaporative cooling developed by Luiten et al. [Phys. Rev. A 53, 381 (1996)] is extended to include the dependence of the elastic scattering cross section on collision energy. We introduce a simple approximation by which the transition range between the low-temperature limit and the unitarity limit is described as well. Applying the modified theory to our measurements on evaporative cooling of metastable helium we find a scattering length |a| = 10(5) nm.

description: Subject and purpose of work: We present the results of the research on the impact of the CAP on the development of family farms in the province of Podlasie. Materials and methods: The research covered farms included in the FADN system. The analysis concerns 2005 and 2014 and was carried out in groups separated due to the their condition and development opportunities: progressive farms, potentially progressive and non-progressive ones. The development opportunities were assessed on the basis of the surplus on self-financing, net investments and fixed asset replacement rates. Results: In all groups of farms the value of assets grew, and the growth rate of assets was the highest in the progressive farms. Only the progressive and potentially progressive farms had self-financing options. Conclusions: Budget transfers targeted at farms affected the intensification of activities related to their modernization, which resulted in the diversification of these entities. The most active recreation of fixed assets took place in the progressive farms. The market activity of potentially progressive farms increased and they are likely to become progressive farms in the future. The non-progressive farms are characterized by their permanent inability to develop.

description: Subject and purpose of work: Agricultural production activity brings about specific environmental effects. The aim of the study was to analyse changes in agricultural production in regions of Poland (NUTS-2) in the context of environmental impact using the gross nitrogen balance. Materials and methods: The analysis covered the medium-term perspective of 2001-2016. The primary source of information was statistical data of the Polish Central Statistical Office (Główny Urząd Statystyczny - GUS). Results: During the 2002-2004 period, the balance of gross nitrogen balance in Poland did not change and amounted to an average of 47.5 kg N∙ha-1 UAA (Utilized Agricultural Area). The progressive extensification of plant production in the following provinces: Slaskie, Malopolskie, Podkarpackie and Swietokrzyskie, is accompanied by a rapid reduction in the stocking density of livestock. Conclusions: The nitrogen balance, highly differentiated regionally, just as its individual elements, show the potential differentiation scale of the agricultural impact on the state of the environment. Very high balance surpluses occurring in the Kujawsko-Pomorskie, Lodzkie and Wielkopolskie provinces may indicate high environmental pressure from the agricultural production.

description: Subject and purpose of work: The objectives of the elaboration are the following: 1) to analyze the regional changes (at the level of poviats) in the number of farms involved in milk production over the period 2002-2010; 2) to present the main factors affecting the ongoing changes in Polish farms oriented at milk production; 3) to determine the impact of the measure 121. “Modernization of agricultural holdings” under the RDP 2007-2013 and the applied system of direct subsidies for the development of farms oriented at milk production. Materials and methods: The work has been prepared on the basis of the analysis and synthesis of the source literature, statistical data collected and the author’s own reflections. Results: In Poland, in the years 2002-2010 there was a distinct regional differentiation in the pace of the ongoing changes in the dairy sector. The regions, where we observe the development of milk production, include almost the entire Podlaskie Province, the northern part of the Mazowieckie Province and the south-eastern part of the Warmińsko-Mazurskie Province. Conclusions: Within the RDP 2007-2013, significant funds were allocated to support the modernization of agricultural farms. Mainly under the measure 121 “Modernization of agricultural holdings” the investments were carried out in relation to the purchase of mobile equipment, they represented 89% of all investments. This was partly due to the actual demand and administrative procedures that stimulated these types of investments.

description: We show that for a wide range of stellar masses, from 0.3 to 20 Msun, and for evolutionary phases from the main sequence to the beginning of the red giant stage, the stellar flux weighted gravity, g_F ~ g/Teff^4, is tightly correlated with absolute bolometric magnitude Mbol. Such a correlation is predicted by stellar evolution theory. We confirm this relation observationally, using a sample of 445 stars with precise stellar parameters. It holds over 17 stellar magnitudes from Mbol = 9.0 mag to -8.0 mag with a scatter of 0.17 mag above Mbol = -3.0 and 0.29 mag below this value. We then test the relation with 2.2 million stars with 6.5 mag > Mbol > 0.5 mag, where 'mass-produced' but robust log g, Teff and Mbol from LAMOST DR5 and Gaia DR2 are available. We find that the same relation holds with a scatter of ~0.2 mag for single stars offering a simple spectroscopic distance estimate good to ~10 percent.

description: We study the evolution of the single-hole spectral function when the ground state of the anisotropic-triangular-lattice antiferromagnet changes from the incommensurate magnetically-ordered phase to the spin-liquid state. In order to describe both of the ground states on equal footing, we use the large-N approach where the transition between these two phases can be obtained by controlling the quantum fluctuations via an 'effective' spin magnitude. Adding a hole into these ground states is described by a t-J type model in the slave-fermion representation. Implications of our results to possible future ARPES experiments on insulating frustrated magnets, especially Cs$_2$CuCl$_4$, are discussed.

description: These 10 collected articles by USDA Rural Development agricultural economist Charles Ling were originally printed in Rural Cooperatives magazine to examine the nature of cooperatives and their place in our free-market economy. “Essential Economic Roles of Farmer Cooperatives” (Published in the Nov./Dec. 2013 issue) summarizes the essence of this work. “What Cooperatives Are (and Aren’t)” (Nov./Dec. 2009) and “What Cooperatives Do” (March/April 2010), explain the economic structure of cooperatives and their role in the marketplace. Together, they examine the economic theory of cooperation as advanced, respectively, by Ivan V. Emelianoff and Edwin G. Nourse. These writings constitute a comprehensive framework for understanding cooperatives. The fourth article, “Dairy Cooperatives: What They Are and What They Do” (March/April 2011) looks at dairy cooperative practices to illustrate how well the theory fits reality, and vice versa. “How Co-ops Do It” (Nov./Dec. 2011) analyzes marketing operations of dairy cooperatives as a means of understanding the economics of co-op marketing. The sixth article, “The Nature of Cooperatives” (Jan./Feb. 2012), attempts to show how cooperatives relate to other market participants through their roles in transaction governance. The seventh article, “Capital Ideas” (May/June 2012), discusses how cooperatives raise equity capital. The eighth article, “The Many Faces of Cooperatives” (Nov./Dec. 2012), shows the variation on the uniqueness of the cooperative business model that constitutes a continuum onto which each type of cooperative falls and is whereby analyzed. The last two articles (Jan./Feb. and Mar./Apr. 2013) exemplify the analysis.
Axial U(1) and spontaneous chiral symmetry breaking within a confining model of the QCD vacuum

description: A model for the QCD vacuum based on domain-like background gluon fields has previously been developed and demonstrated to exhibit confinement of quarks and strong correlation of the local chirality of quark modes and duality of the background gluon field. On the boundary of the j-th domain, quark fluctuations satisfy chirality violating boundary conditions parametrized by a chiral angle $α_j$ which is treated as a collective variable. The dependence of the free energy of an ensemble of $N\to\infty$ domains on $\{α_j, j=1... N\}$ is studied. For one massless flavour there are only two degenerate minima ($α_j=0,π$ $\forall j$) due to the contribution of the anomaly to the free energy, which suppresses the continuous U(1) degeneracy. The residual discrete symmetry is spontaneously broken with a quark condensate of $-(238 {\rm{MeV}})^3.$ For $N_f$ massless flavours a continuous $SU(N_f)_L\times SU(N_f)_R$ degeneracy appears, while the $U_A(1)$ direction remains suppressed.

description: In this project, we aim to test whether language framing in logos can influence consumers’ purchase intent of upcycled food in UBC dining halls. To explore this question, we designed a logo for upcycled food. The plain logo was used as the control condition, the logo with an informative descriptor of upcycled food as the informational condition, and the logo with an emotive descriptor of upcycled food as the emotional condition. It was hypothesized that the informational condition would have the strongest effect in convincing consumers to purchase upcycled food, followed by the emotional and control conditions. Carried out as an online survey, 246 participants completed the experiment, giving us enough statistical power. Participants were shown the logos corresponding to the conditions they were randomly assigned, then asked to rate their purchase intent on a 9-point Likert scale based on the logo they saw. No significant difference among all three groups regarding purchase intent (p = .08) was found. However, excitement was found as significantly higher in the emotional condition than in the control condition (p = .02). This result indicates that more research is necessary to examine logos’ effects in different scenarios where consumers might encounter upcycled food.

description: The behavior of some high temperature superconductors (HTSC) such as $\rm La_{2-x}Sr_{x}CuO_{4}$ and $\rm Bi_{2}Sr_{2-x}La_xCuO_{6+δ}$, at very high magnetic field, is similar to that of thin films of amorphous InOx near the magnetic field-tuned superconductor-insulator transition. Analyzing the InOx data at high fields in terms of persisting local pairing amplitude, we argue by analogy that local pairing amplitude also persists well into the dissipative state of the HTSCs, the regime commonly denoted as the "normal state" in very high magnetic field experiments.

description: This guide outlines the process of organizing a cooperative business and provides information on the potential steps involved and some important aspects of cooperative development. A cooperative business is briefly described, including its structure and basic principles. Twelve steps involved in most cooperative development projects are introduced and explained. Important considerations—such as practitioner principles, pitfalls to avoid, cooperative capitalization, legal aspects of cooperative development, and general rules for success—are presented. This information should provide a reader with a comprehensive understanding of the cooperative development process. While this report focuses on agricultural cooperative development, it also contains information that is pertinent to non-agricultural applications. The cooperative business structure, shown to be successful in agriculture, has also been useful in helping others obtain benefits or provide needed services in areas such as housing, utilities, finance, healthcare, homecare, childcare, grocery retailing, manufacturing, business support services, and more.

description: We perform metastability exchange optical pumping of helium-3 in a strong magnetic field of 1.5 T. The achieved nuclear polarization, from 80% at 1.33 mbar to 25% at 67 mbar, shows a substantial improvement at high pressures with respect to standard low-field optical pumping. The specific mechanisms of metastability exchange optical pumping at high field are investigated, advantages and intrinsic limitations are discussed. From a practical point of view, our results open the way to alternative technological solutions for polarized helium-3 applications and in particular for magnetic resonance imaging of human lungs.

description: Charging of upper and lower horizontal boundaries of extensive layer clouds results from current flow in the global electric circuit. Layer-cloud charge accumulation has previously been considered a solely electrostatic phenomenon, but it does not occur in isolation from meteorological processes, which can transport charge. Thin layer clouds provide special circumstances for investigating this dynamical charge transport, as disruption at the cloud-top may reach the cloud base, observable from the surface. Here, a thin (~300 m) persistent layer-cloud with base at 300 m and strong wind shear at cloud-top was observed to generate strongly correlated fluctuations in cloud base height, optical thickness and surface electric Potential Gradient (PG) beneath. PG changes are identified to precede the cloud base fluctuations by 2 minutes, consistent with shear-induced cloud-top electrical changes followed by cloud base changes. These observations demonstrate, for the first time, dynamically driven modification of charge within a layer-cloud. Even in weakly charged layer-clouds, redistribution of charge will modify local electric fields within the cloud and the collisional behaviour of interacting charged cloud droplets. Local field intensification may also explain previously observed electrostatic discharges in warm clouds.

description: A qualitative methodology was used to explore the narratives of participants about recovery from the initial experiences of psychosis, and a diagnosis of schizophrenia. A process of psychosocial adjustment to the experiences of psychosis, and a diagnosis of schizophrenia, appeared central to recovery. The psychosocial impact of a diagnosis of schizophrenia on this adjustment process was also explored. Factors that impeded, or assisted, this process of adjustment were identified.

 Semi structured interviews were conducted with 12 participants, six men and six women, who had received a diagnosis of schizophrenia within the last ten years. These interviews were audiotaped, and transcribed, and Grounded Theory was used to analyse the data.

 The results formed a temporal stage model of the process of adjustment to the experiences of psychosis and a diagnosis of schizophrenia. Implications for clinical practice and further research are discussed.

description: We offer a discussion on the strong field regime predictions of two families of theories that deviate from General Relativity in different aspects: $f(R)$-gravity and Scalar-Tensor-Vector Gravity (STVG). We discuss astrophysical effects in models based upon both matter and vacuum solutions of such theories. In particular, we analize neutron star structure and the constraints on the parameters of the theories introduced by the latest observations. We also review black hole solutions and several astrophysical consequences of them, including accretion disks and jets. Finally, we report on the implications of the detection of various gravitational wave events for these theories.

title: Regulation of leukocyte cytokine production by inhibitors of intracellular signalling pathways
Creators: name: Rapecki, Stephen Edward
Publisher: name: The Open University
Year: 2001

description: The activation of leukocytes during inflammation results in the engagement of many related intracellular signalling pathways. The role of two key proteins families, phosphodiesterase (PDE) and Src kinase, has been assessed in these signalling pathways using specific inhibitors.

 Inhibition of phosphodiesterase type 4 (PDE4) in lipopolysaccharide (EPS) stimulated human peripheral blood mononuclear cells (PBMC) resulted in the inhibition of TNF-a by an IL-10-independent mechanism. This is in contrast to other agents that elevate cAMP which in turn inhibit TNF-a synthesis by an IL-10-dependent mechanism. When PBMC were stimulated with EPS plus IFN-y, inhibition of PDE4 resulted in an altered effect on cytokine production, elevating IE-10 while still inhibiting TNF-a.

 Inhibition of PDE4 in activated T cells only weakly inhibited cellular proliferation. In contrast, PDE4 inhibitors were potent but non-selective inhibitors of T-cell cytokine production. In contrast to studies in murine cells, inhibition of T-cell activation correlates with inhibition of binding to a high-affinity Rolipram binding site on the PDE4 protein.

 Kinases from the Src family (Eck, Fyn and Eyn) have been implicated in signalling via the T-cell receptor (TCR) on lymphocytes and the high affinity IgE receptor (FceRI) on mast cells. Potent inhibitors of Src kinases blocked T-cell proliferation and cytokine generation in response to specific ligation of the TCR. However, activation of T-cells by multiple costimulatory pathways was much more resistant to Src kinase inhibition. Inhibition of Src kinase in human cord blood-derived mast cells inhibited IgE-dependent degranulation of these cells. This indicates that Src kinase inhibitors may be useful in down-regulating allergic responses. Conversely, inhibitors of PDE4 and PDE type 7 (PDE7) did not prevent mast cell degranulation.

 The observation that PDE4 inhibitors can regulate monocyte cytokine generation further supports the view that these agents could have therapeutic benefit in a number of inflammatory diseases such as asthma, arthritis and inflammatory bowel disease. The failure of Src kinase inhibitors to modify T cell signalling activated by multiple pathways indicates redundancy in these signalling pathways and therefore Src kinases may not represent good targets for immunomodulation. However, a selective Src kinase inhibitor could represent a good target for an anti-allergic drug.

description: Topological surface states with intrinsic magnetic ordering in the MnBi$_2$Te$_4$(Bi$_2$Te$_3$)$_n$ compounds have been predicted to host rich topological phenomena including quantized anomalous Hall effect and axion insulator state. Here we use scanning tunneling microscopy to image the surface Dirac fermions in MnBi$_2$Te$_4$ and MnBi$_4$Te$_7$. We have determined the energy dispersion and helical spin texture of the surface states through quasiparticle interference patterns far above Dirac energy, which confirms its topological nature. Approaching the Dirac point, the native defects in the MnBi$_2$Te$_4$ septuple layer give rise to resonance states which extend spatially and potentially hinder the detection of a mass gap in the spectra. Our results demonstrate that regulating defects is essential to realize exotic topological states at higher temperatures in these compounds.

description: Screening cluttered and occluded contraband items from baggage X-ray scans is a cumbersome task even for the expert security staff. This paper presents a novel strategy that extends a conventional encoder-decoder architecture to perform instance-aware segmentation and extract merged instances of contraband items without using any additional sub-network or an object detector. The encoder-decoder network first performs conventional semantic segmentation and retrieves cluttered baggage items. The model then incrementally evolves during training to recognize individual instances using significantly reduced training batches. To avoid catastrophic forgetting, a novel objective function minimizes the network loss in each iteration by retaining the previously acquired knowledge while learning new class representations and resolving their complex structural inter-dependencies through Bayesian inference. A thorough evaluation of our framework on two publicly available X-ray datasets shows that it outperforms state-of-the-art methods, especially within the challenging cluttered scenarios, while achieving an optimal trade-off between detection accuracy and efficiency.

description: We study a Newtonian cosmological model in the context of a noncommutative space. It is shown that the trajectories of a test particle undergo modifications such that it no longer satisfies the cosmological principle. For the case of a positive cosmological constant, spiral trajectories are obtained and corrections to the Hubble constant appear. It is also shown that, in the limit of a strong noncommutative parameter, the model is closely related to a particle in a Gödel-type metric.

description: We present observations of a remarkable submillimetre-selected galaxy, SMMJ16359+6612. This distant galaxy lies behind the core of a massive cluster of galaxies, A2218, and is gravitationally lensed by the foreground cluster into three discrete images which were identified in deep submillimetre maps of the cluster core at both 450 and 850micron. Subsequent follow-up using deep optical and NIR images identify a faint counterpart to each of the 3 images, with similar red optical--NIR colours and HST morphologies. By exploiting a detailed mass model for the cluster lens we estimate that the combined images of this galaxy are magnified by a factor of ~45, implying that this galaxy would have un-lensed magnitudes K_s=22.9 and I=26.1, and an un-lensed 850micron flux density of only 0.8mJy. Moreover, the highly constrained lens model predicted the redshift of SMMJ16359+6612 to be z=2.6+/-0.4. We confirm this estimate using deep optical and NIR Keck spectroscopy, measuring a redshift of z=2.516. SMMJ16359+6612 is the faintest submm-selected galaxy so far identified with a precise redshift. Thanks to the large gravitational magnification of this source, we identify 3 sub-components in this submm galaxy, which are also seen in the NIRSPEC data, arguing for either a strong dust (lane) absorption or a merger. Interestingly, there are 2 other highly-amplified galaxies at almost identical redshifts in this field (although neither is a strong submm emitter). The 3 galaxies lie within a ~100kpc region on the background sky, suggesting this submm galaxy is located in a dense high-redshift group.

description: In addition to providing extremely valuable products, bees are one of the species capable of pollinating entomophilic plants. Hence, supporting the development of beekeeping in the face of their importance to humanity seems to be extremely important. In Poland, this task is also carried out using funds from the European Union as part of the Bee Market Program Support Programs. The aim of the article is therefore to determine the role of funds originating from the European Union in the development of beekeeping in the Wielkopolskie voivodship on the example of the Provincial Union of Beekeepers in Poznań. First of all unpublished JPA data in Poznań, as well as the results of surveys were used for the research. The results of the research indicate a positive impact of EU funds on the development of beekeeping in the Wielkopolskie voivodship, especially due to the considerable interest in the mechanism among beekeepers. / Synopsis.
