description: This work presents a novel reconfigurable architecture for Low Latency Graph Neural Network (LL-GNN) designs for particle detectors, delivering unprecedented low latency performance. Incorporating FPGA-based GNNs into particle detectors presents a unique challenge since it requires sub-microsecond latency to deploy the networks for online event selection with a data rate of hundreds of terabytes per second in the Level-1 triggers at the CERN Large Hadron Collider experiments. This paper proposes a novel outer-product based matrix multiplication approach, which is enhanced by exploiting the structured adjacency matrix and a column-major data layout. Moreover, a fusion step is introduced to further reduce the end-to-end design latency by eliminating unnecessary boundaries. Furthermore, a GNN-specific algorithm-hardware co-design approach is presented which not only finds a design with a much better latency but also finds a high accuracy design under given latency constraints. To facilitate this, a customizable template for this low latency GNN hardware architecture has been designed and open-sourced, which enables the generation of low-latency FPGA designs with efficient resource utilization using a high-level synthesis tool. Evaluation results show that our FPGA implementation is up to 9.0 times faster and achieves up to 13.1 times higher power efficiency than a GPU implementation. Compared to the previous FPGA implementations, this work achieves 6.51 to 16.7 times lower latency. Moreover, the latency of our FPGA design is sufficiently low to enable deployment of GNNs in a sub-microsecond, real-time collider trigger system, enabling it to benefit from improved accuracy. The proposed LL-GNN design advances the next generation of trigger systems by enabling sophisticated algorithms to process experimental data efficiently.

description: The dramatic rise in the ratio of Canada's average house price to average rent has led to speculation that there is a bubble in the Canadian housing market. Others have argued, however, that the currently high level of house prices may be rationalized by the low cost of financing, given the decline in interest rates over the last two decades. In this article, we assess these arguments through the lens of a simple asset pricing model applied to city-level data. We quantify the extent to which excess growth in Canadian house prices depends on the nature of the current regime governing real interest rates, expections of rent growth in different cities and variations in property taxes.

Submicron atmospheric aerosols have been studied to get a better handle on their contribution to the earthâs radiative forcing. Samples were collected on filters using a concentrator and analyzed for organic content. This study has been done in two field projects, the Asian Pacific Regional Aerosol Characterization Experiment (ACE-Asia) and the Dynamics and Chemistry of Marine Stratocumulus Phase II: Entrainment Studies (DYCOMS II), with a two-stage and a three-stage concentrator. During ACE-Asia submicron aerosol samples were collected from Hawaii to Japan on board the NOAA ship Ronald H. Brown and the NCAR C-130 aircraft. The DYCOMS II samples were taken on board the NCAR C-130 aircraft about 322 km off the San Diego coast at various altitudes in and out of the marine stratocumulus clouds. A comparison of chemical composition has been done for an ACE-Asia case when the C-130 and ship were sampling in the same air mass. The same organics appear to be present for the RHB and C-130, but the C-130 sample shows a higher mass loading. In-cloud measurements taken during DYCOMS II by the concentrator and a Counterflow Virtual Impactor (CVI) were also compared. The CVI sample shows a higher mass loading than the concentrator. Both CVI and concentrator samples taken have a lower absorbance by a factor of 10 compared to the ACE-Asia measurements. These differences can be attributed to the geographic location, DYCOMS II being in a pristine marine environment and ACE-Asia in an area with pollution and dust events.

description: Statistical properties of the electron transport flowing through nanostructures are strongly influenced by the interactions, geometry of the system and/or by type of the external electrodes. These factors affect not only the average current induced in the system but also contribute to fluctuations in the flux of charges and their correlations. Due to possible applications of the hybrid nano-systems, containing one or more superconducting electrodes, a detailed understanding of the flow of charge and its fluctuations seems to be of primary importance. Coulomb repulsion between electrons usually strongly affect the current-current correlation function. In this work we study the correlations in the charge flow through such interacting quantum dot contacted to one superconducting and two normal electrodes. This set-up allows for analysis of the Andreev scattering events in the correlations of currents flowing between external electrodes and, in particular, gives access to cross-correlations between currents from/to different normal electrodes. Our approach relies on the master equation technique, which properly captures the Coulomb interactions. We study the finite frequency correlations and find the relaxation processes, related to the high frequency charge and low frequency polarisation fluctuations. The multiterminal structure of here studied single electron device allows to analyze a competition between the intra- and inter-channel correlations. In the appropriate limit of the interacting quantum dot embedded between two normal electrodes our calculations quantitatively describe the recent experimental data on the frequency dependent correlations. This shows a promising potential of the method for description of the hybrid systems with superconducting electrode(s).
Constructing national identity: A qualitative analysis of separatism

description: The study of public perceptions on nationalism continues to be problematic for sociology and the social sciences. For example, do the people of Catalan think of themselves first as being Catalonians, or are they Spanish or even European? Likewise, if the people have a hard time perceiving the true nature of their community identity, then external (i.e. international) public perceptions concerning the same agenda should be problematic as well. This dissertation limits its focus to external (international) media perceptions surrounding the social construction of national identity movements. The three national identity movements examined in this dissertation are Chiapas (Mexico), East Timor (formerly part of Indonesia), and Quebec (Canada). Theoretical basis for the study is drawn from Habermas' conceptualization of the public sphere (conflict theoretical approach), and is supported by the theoretical approaches of W. I. Thomas (definition of a situation), Berger and Luckmann's (social constructions of reality), and Foucault (post-modernist theory) to deconstruct international perceptions of the three social movements. A model is introduced to show the flow of social construction from competing factions within and outside a national identity movement to the outcomes that are produced and reported by international media sources covering aspects of social action. A sub-model is offered as a supplemental tool to the primary model, in order to organize (or deconstruct) the frame of major competing interests affecting social construction of the national identity movement cases. The study incorporated a qualitative methodology, which included assembling a data set consisting of 2,960 units (Chiapas N = 28; East Timor N = 1,030; and Quebec N = 1,902). Each data unit represented a separate international printed media source. Parameters for these data included a longitudinal range covering 1990--2000, and were coded into five major social institutional categories (political, economic, arts and entertainment, media and military). These categories were used to identify institutional shifts giving rise to the social construction of the three national identity movement cases during the given historical frame. Frequencies were tabulated for each institution category, by case, and by year to gain a better understanding of the longitudinal social construction of national identity.

description: The interaction of light and swift electrons has enabled phase-coherent manipulation and acceleration of electron wavepackets. Here we investigate this interaction in a new regime where low-energy electrons (~20-200 eV) interact with a phase-matched light field. Our analytical and one-dimensional numerical study shows that slow electrons are subject to strong confinement in the energy domain due to the non-vanishing curvature of the electron dispersion. The spectral trap is tunable and an appropriate choice of light field parameters can reduce the interaction dynamics to only two energy states. The capacity to trap electrons expands the scope of electron beam physics, free-electron quantum optics and quantum simulators.

description: Social networks are an important component in understanding the decision to consume ad- dictive substances. They capture the role of limited access, peer influence, and social acceptance and tolerance. However, despite the empirical evidence of their role, they have been absent from theoretical models. This paper proposes a mechanism through which agents can influence each other in their decision to consume an addictive good. An agent's decision is sensitive to her state of addiction as well as to the composition of her neighbourhood. The model is consistent with the empirical evidence that peer influence can work in both ways: influencing an individual to use and helping them to quit. The structure of the network has important implications on the outcome of agents' decisions as well as the effectiveness of policies aimed at limiting use of addictive substances through deterrence. I provide a network-based explanation of why usage rates can vary across otherwise similar agents and show how in some situations encouraging network ties can lead to lower use while in others it can have the opposite effect. Furthermore, I explore the effect of networks on diffusion of addiction and, using simulations, find that addic- tion spreads faster in an environment where there are few strong links than in one with many weak links.

Using radar data to estimate snowfall rates is of great interest in regions of rough terrain. Snowfall rates can provide information on potential flood hazards, water resource problems, and aide in agricultural planning. Several attempts have been made estimating snowfall rates using radar data, but a sufficient method is not available. Therefore, in this study a technique is developed using polarimetric radar data to estimate snowfall from data recorded during the Mesoscale Alpine Programme (MAP). MAP is a field experiment that took place in Northern Italy whose goal was to understand heavy precipitation events including flash-floods. Data was collected remotely by S-Pol, which is the National Center for Atmospheric Research (NCAR) ground based S-Band dual linear switchable polarization radar with copolar and cross-polar components, plus NCAR's in-situ particle measuring system probes mounted on the Electra aircraft. This study attempts to find a correlation between polarimetric variables and snowfall rates. In-situ aircraft data provides information on hydrometeor size, shape, and concentration. To estimate hydrometeor density and fall velocity, the aircraft data has to be compared to polarimetric information from S-Pol. For this purpose, it is important to create and validate a matching program that correlates points between aircraft flight tracks and radar scans. Such matching was realized for the first time among the scientific community at NCAR. This study will utilize this matching program to provide hydrometeor concentration, density, and fall velocity in a cloud, and thus determine snowfall rate.

description: Changes in the world economy, and in particular relations between the economic, environmental, social and political aspects, have become the starting point for reflection on the path of socio-economic development. One of the new approaches is the green economy. The importance of this approach is reflected in the growing constraints to sustain long-term growth in the traditional approach according to the Solow model and the occurrence of periodic significant deviations from the state of equilibrium. Referring to this problem, the aim of the article was to indicate the determinants of the green economy development in the Visegrad Group countries. Panel regression was used to identify and characterize the nature and impact of individual economic, social and environmental factors on the development of the green economy sector. Time range covers the years 2004-2016. Due to the lack of a universal method for evaluating the degree of development of this concept, the study conducted may be considered one of the proposals within the literature. The results obtained in this way can be used to interpret the determinants of green economy development. / Synopsis.

Wzrost znaczenia tego podejścia upatruje się w rosnących ograniczeniach utrzymania długofalowego wzrostu w tradycyjnym podejściu zgodnie z modelem Solowa i występowania okresowo znacznych odchyleń uzyskiwanych wyników rocznych od stanu równowagi. Odnosząc się do tego problemu za cel artykułu przyjęto wskazanie uwarunkowań rozwoju zielonej gospodarki w krajach Grupy Wyszehradzkiej. W celu identyfikacji oraz określenia oddziaływania poszczególnych czynników ekonomicznych, społecznych i środowiskowych na rozwój sektora zielonej gospodarki zastosowano regresję panelową. Zakres czasowy obejmuje lata 2004-2016. Ze względu na brak uniwersalnej metody oceny stopnia rozwoju tej koncepcji, przeprowadzone badanie może być uznane za jedną z propozycji w ramach przedmiotu literatury. Uzyskane w ten sposób wyniki mogą służyć do interpretacji uwarunkowań rozwoju zielonej gospodarki.

description: The ongoing socio-economic transformations in Poland, including the processes of liberalization and globalization, increased competition and changing expectations of buyers cause the conditions in which agriculture operates to be more and more complex. The purpose of the research was to identify barriers to the development of farms, in the opinion of farmers who in their operation used land from the Agricultural Property Resources of the State Treasury (ZWRSP). The study covered 167 farms located in the area of Warmian-Masurian Voivodeship. The obtained results were presented for the entire studied group and according to the form of land management from the ZWRSP. The research shows that the development of farms, according to the respondents, is mainly inhibited by cost and price factors, such as: unstable purchase prices, high costs of agricultural production, high prices for means of production and lack of capital for development. / Synopsis.

description: Light-matter coupling involving classical and quantum light offers a wide range of possibilities to tune the electronic properties of correlated quantum materials. Two paradigmatic results are the dynamical localization of electrons and the ultrafast control of spin dynamics, which have been discussed within classical Floquet engineering and in the deep quantum regime where vacuum fluctuations modify the properties of materials. Here we discuss how these two extreme limits are interpolated by a cavity which is driven to the excited states. In particular, this is achieved by formulating a Schrieffer-Wolff transformation for the cavity-coupled system, which is mathematically analogous to its Floquet counterpart. Some of the extraordinary results of Floquet-engineering, such as the sign reversal of the exchange interaction or electronic tunneling, which are not obtained by coupling to a dark cavity, can already be realized with a single-photon state (no coherent states are needed). The analytic results are verified and extended with numerical simulations on a two-site Hubbard model coupled to a driven cavity mode. Our results generalize the well-established Floquet-engineering of correlated electrons to the regime of quantum light. It opens up a new pathway of controlling properties of quantum materials with high tunability and low energy dissipation.

It has recently been proposed, but not proven, that bacteria associated with plant roots may produce the volatile hydrocarbon, isoprene, as a protective mechanism. Isoprene might act to repel organisms that feed on these bacteria or the host roots. The work presented here is an initial test of this idea, aiming to determine if isoprene-producing bacteria are common in the rhizosphere (the region in which living plant roots and micro-organisms interact). Bacteria associated with beet (Beta vulgaris) roots were isolated by culturing the soil adhering to the peel. All isolates were screened for isoprene emission and other phenotypic characteristics. Isoprene emission was detected by an isothermal (64Â° C) gas chromatography system. All 96 isolates produced some isoprene and a small percentage (28%) of isolates were very-high or high isoprene emitters. These results show that isoprene-producing bacteria are common in the beet rhizosphere. Identity tests of the 13 very-high isoprene emitters revealed much diversity. The phenotypic characteristics tested included Gram positive/negative cell surface, thermotolerance, fluorescent pigment, catalase production and spore formation. These results suggest that the very-high isoprene emitters in the beet rhizosphere are Gram-negative and not Gram-positive genera as well as all being catalase positive. Initial attempts to use the Polymerase Chain Reaction (PCR) to identify unknown isolates are described. Use of the PCR and further quantification of isoprene-producing bacteria will identify and improve understanding of the role of isoprene in the rhizosphere. This

Supergranulation is characterized by large-scale horizontal flows of gas in the photosphere and is outlined by network which is composed of magnetic flux tubes. We made preliminary measurements, using data from the Precision Solar Photometric Telescope (PSPT) at Mauna Loa Solar Observatory in Hawaii, of the intensity contrast associated with supergranular flows at two different wavelengths (red and blue). There is a direct correlation between continuum brightness and temperature and this allowed us to determine the temperature fluctuations associated with supergranulation. Supergranules were found to be dimmer in the center and brighter on the boundary. We suspected that supergranulation is convection except bright network is overwhelming the convective signal. In order to detect the convective signal, Kitt Peak magnetograms were coaligned with CaIIK images from the PSPT and then the magnetic contribution was masked. We again measured the intensity contrast, this time without the magnetic contribution to see if a convective signal could be detected. Our results hint that supergranulation may indeed be convection; however, more samples need to be collected in order to increase our level of confidence. In addition to furthering our understanding of solar convection, this research may yield insight into the role network plays in solar irradiance variations.

We analyzed CO measurements in the upper troposphere and lower stratosphere via infrared spectroscopy using a Fourier Transform Infrared (FTIR) spectrometer that was flown aboard two aircraft, a NASA DC8 and NCAR Sabreliner. Measurements were made between 1978-1992. Measurements of stratospheric CO can aid in understanding transport in the lower stratosphere. Calculated reference spectra were generated to analyze the observed spectra produced by the spectrometer using standard temperature and mixing ratio profiles and molecular line parameters. Nonlinear least squares fitting were used to match calculated reference spectra with observed spectra. The CO amount in the best-fit reference spectrum was assigned to the observed spectrum. CO column was corrected to be the amount above the 200mb pressure surface because column varies rapidly with aircraft altitude. CO column was plotted against latitude and then divided into seasons to observe any seasonal variations. Higher columns occurred near the equator while lower columns occurred near the poles. This characteristic was consistent in the seasonal plots, indicating little seasonal variations. Higher CO column near the equator is explained by presence of tropospheric air that has a higher density of CO and CO entering the stratosphere at the equator. Lower CO column near the poles is due to presence of only stratospheric air that has less CO. The observed column was similar in both hemispheres near the poles, where the observation is wholly stratospheric, but asymmetric about 20 because of the large interhemispheric gradient in tropospheric CO.

description: Learning disabled youth represent the largest portion of special education youth in juvenile corrections. Race, gender, poverty, and urban living are all factors shown to increase the likelihood of being classified as learning disabled and identified for placement in special education, and at-risk for school failure. Research demonstrates that at-risk youth are often several years below grade level in one or more academic areas, have higher absenteeism rates, increased grade-level retention, higher dropout rates, and poorer post-school outcomes, including lower levels of meaningful employment, and higher arrest, incarceration, and recidivism rates. While research has identified a variety of factors linking academic failure and delinquency, it has been grounded in the identification of person-centered factors rather than external factors such as those found in the home, school, and community. The present study is a qualitative inquiry of adolescent learning disabled youths' perceptions of their past public schooling experiences. The study expands an examination of schooling to include the additional high-risk contexts of the youths' home and community. In-depth interviews were the primary data collection tool used for accessing the stories of these adolescent juveniles. The findings of the study suggest that youth responded and made decisions relative to their needs and socially stigmatized positioning as learning disabled students; key events co-occurring with the tasks challenges, and coping abilities of adolescence contributed to their interrupted school careers; and, persistent home, school, and community risk factors exceeded protective factors available to these adolescent students, limiting their ability to successfully adapt and respond. The distal impact of these factors on their development is demonstrated in their poor educational outcomes and increased incidences of court involvement. Students receive insufficient opportunities in their risk-prone contexts for a level of social development that lays the groundwork for adjustment and competence in adolescence and as they move toward adult roles.

description: The article presents a study on the phenomenon of pig gaps in the perspective of pig, cattle, and poultry farming in Poland. The work attempts to define the phenomenon itself as well as to show the reasons for its occurrence and significance for the Polish economy. The study used a cross-spectral analysis, which indicated cyclical relationships and shifts between the studied time series. The methodology of the work was based on a simplified spectral analysis, i.e. the use of the square of coherence, spectral density and phase spectrum. In addition, the article uses a comparative method for selected production volumes. The results were analyzed in the context of occurrence of pig cycles for breeding and cultivation. The study showed the occurrence of the relationship between pig breeding and wheat and rye cultivation.

description: The article aims to introduce the issue of food waste and all attempts to prevent action. Business and politics are almost interdependent, and any discussion of an economic nature is not complete without a political contribution. The role of politics and politicians in shaping economic activities was and is widely discussed. In the article, there will be a discussion on the problems of food losses and waste in Poland as the member of EU and in India. The idea of the topic came during the tenure of collaboration between representatives of both departments. Conclusions of the study found some similarities and a lot of differences between the countries. Studies have shown that negative attitude of house-hold towards food waste is not frequently reflected in consumers’ behavior, despite their fundamental knowledge on how to reduce food waste. Properly selected and presented information will stimulate both consumer’s attitude and behavior.

Dimension-Free Square Function Estimates for Dunkl Operators

description: Dunkl operators may be regarded as differential-difference operators parameterized by finite reflection groups and multiplicity functions. In this paper, the Littlewood--Paley square function for Dunkl heat flows in $\mathbb{R}^d$ is introduced by employing the full "gradient" induced by the corresponding carré du champ operator and then the $L^p$ boundedness is studied for all $p\in(1,\infty)$. For $p\in(1,2]$, we successfully adapt Stein's heat flows approach to overcome the difficulty caused by the difference part of the Dunkl operator and establish the $L^p$ boundedness, while for $p\in[2,\infty)$, we restrict to a particular case when the corresponding Weyl group is isomorphic to $\mathbb{Z}_2^d$ and apply a probabilistic method to prove the $L^p$ boundedness. In the latter case, the curvature-dimension inequality for Dunkl operators in the sense of Bakry--Emery, which may be of independent interest, plays a crucial role. The results are dimension-free.

Tornadic storm

Preliminary results from observations of a severe thunderstorm near Bird City, Kansas on 29 June 2000 during the Severe Thunderstorm Electrification and Precipitation Study (STEPS) are presented. Storm characteristics included large hail, frequent positive cloud-to-ground lightning, and an F1 tornado. The tornado was present for the period 2328-2344 UTC. Analysis of single radar measurements of reflectivity and radial velocity showed that the storm formed ahead of an advancing surface boundary and turned right near the time that it became tornadic and electrically active. A noteworthy tornadic vortex signature and mesocyclone were observed, even though a well-defined hook echo (often interpreted as an indicator of tornadic potential) was missing. Triple-Doppler wind synthesis was employed for five storm-volume scans for the period 2305-2343 UTC. Three-dimensional wind fields indicated that this storm had a sequence of small, but intense, updrafts that followed a larger-scale, quasi-steady path that entered the storm on the southwest flank, ascended through the storm turning anticyclonically, and exited into the anvil on the northeast flank. This quasi-steady airflow with embedded updrafts (a distinctly multicellular behavior) of some so-called supercells has been documented in the literature and is discussed herein. At times, the storm exhibited weak echo regions coincident with updrafts, and there is evidence that a rear-flank downdraft was present. When compared to previous classification criteria, this storm resembled a âclassicâ supercell for only a short period, but rather it exhibited characteristics across several regimes throughout its lifetime.
