description: Abstract: "This paper describes an improved, user friendly version of the computer package PROSYN -- a mixed-integer nonlinear programming (MINLP) process synthesizer. PROSYN is an implementation of the modeling and decomposition (M/D) strategy by Kocis and Grossmann (1989) and the outer approximation and equality relaxation algorithm (OA/ER) by Kocis and Grossmann (1987). Main characteristic [sic] of the new version of PROSYN is that it enables automated execution of simultaneous topology and parameter optimization of processes. Optimization of each NLP subproblem is performed only on the existing units rather than on the entire superstructure which substantially reduces the size of the NLP subproblems. In order to reduce undesirable effects of nonconvexities involved in the master problem the OA/ER algorithm has been improved by the use of an augmented penalty function. A simple process simulator has been built in to perform automated initialization of the first NLP step. A comprehensive PROSYN's library of models for basic process units and interconnection nodes, and a comprehensive library of basic physical properties for the most common chemical components have been developed. This enables to carry out [sic] an automated generation of a complex model representation for a superstructure in which the topology is specified by a concise interface. PROSYN allows to run in interactive mode and thus provides the user with a good control and supervision of calculations instead of having the procedure to be totally automated. PROSYN allows to carry out process synthesis at two basic levels of complexity: MINLP optimization through M/D and simultaneous heat integration including HEN costs. Applications with PROSYN are demonstrated with two example problems."

description: Abstract: "Optimization strategies based on detailed and rigorous models of process flowsheets have been of interest to process engineers for the past 25 years. Here we review earlier optimization strategies and emphasize more recent strategies based on Successive Quadratic Programming (SQP). These strategies allow the simultaneous solution and optimization of the process model and thus lead to significant reductions in the computational effort for an optimization study. Several examples are presented to define the optimization problem and demonstrate the performance of the simultaneous strategies. Finally, some open research questions are described and future directions in process optimization are briefly discussed."

description: Recent ROSAT studies have identified a significant population of Active Galactic Nuclei (AGN) that are notably faint in soft X-rays relative to their optical fluxes. Are these AGN intrinsically X-ray weak or are they just highly absorbed? Brandt, Laor & Wills have systematically examined the optical and UV spectral properties of a well-defined sample of these soft X-ray weak (SXW) AGN drawn from the Boroson & Green sample of all the Palomar Green AGN with z<0.5. We present ASCA observations of three of these SXW AGN: PG 1011-040, PG 1535+547 (Mrk 486), and PG 2112+059. In general, our ASCA observations support the intrinsic absorption scenario for explaining soft X-ray weakness; both PG 1535+547 and PG 2112+059 show significant column densities (N_H~10^22-10^23 cm^-2) of absorbing gas. Interestingly, PG 1011-040 shows no spectral evidence for X-ray absorption. The weak X-ray emission may result from very strong absorption of a partially covered source, or this AGN may be intrinsically X-ray weak. PG 2112+059 is a Broad Absorption Line (BAL) QSO, and we find it to have the highest X-ray flux known of this class. It shows a typical power-law X-ray continuum above 3 keV; this is the first direct evidence that BAL QSOs indeed have normal X-ray continua underlying their intrinsic absorption. Finally, marked variability between the ROSAT and ASCA observations of PG 1535+547 and PG 2112+059 suggests that the soft X-ray weak designation may be transient, and multi-epoch 0.1-10.0 keV X-ray observations are required to constrain variability of the absorber and continuum.

description: In this paper, we consider two different subjects: the algebra of universal characters $S_{[λ,μ]}({\bf x},{\bf y})$ (a generalization of Schur functions) and the phase model of strongly correlated bosons. We find that the two-site generalized phase model can be realized in the algebra of universal characters, and the entries in the monodromy matrix of the phase model can be represented by the vertex operators $Γ_i^\pm(z) (i=1,2)$ which generate universal characters. Meanwhile, we find that these vertex operators can also be used to obtain the A-model topological string partition function on $\mathbb C^3$.

description: RESUMO

 

O artigo aborda a urgente necessidade de repensarmos o modelo de formação policial e em que medida as questões relacionadas à ética da alteridade, definidas por Emmanuel Levinas, podem funcionar como referenciais de sentido para esse trabalho. A temática do artigo se articula e justifica em função da necessidade de respondermos aos inúmeros casos de abusos de violência cometidos por agentes de segurança pública, mais especificamente por policiais militares, que, ao nosso ver, estão intimamente correlacionados à formação precária, deficiente e insuficiente que esses recebem. A partir disso, considera-se em que medida é preciso incorporar elementos que promovam maior dignidade e respeito aos Direitos Humanos e como a responsabilidade pelo Outro, no viés definido por Levinas, pode ser elemento singular para a formação policial. Ao final, pretende-se justificar a necessidade de fortalecimento dos princípios de respeito à alteridade e do diálogo dentro do processo de formação e da atuação profissional de futuros policiais e dos policiais já em trabalho, através de uma formação continuada.

description: Voice over Internet Protocol (VoIP) applications (apps) provide convenient and low cost means for users to communicate and share information with each other in real-time. Day by day, the popularity of such apps is increasing, and people produce and share a huge amount of data, including their personal and sensitive information. This might lead to several privacy issues, such as revealing user contacts, private messages or personal photos. Therefore, having an up-to-date forensic understanding of these apps is necessary. This chapter presents analysis of forensically valuable remnants of three popular Mobile VoIP (mVoIP) apps on Google Play store, namely: Viber, Skype, and WhatsApp Messenger, in order to figure out to what extent these apps reveal forensically valuable information about the users activities. We performed a thorough investigative study of these three mVoIP apps on smartphone devices. Our experimental results show that several artefacts, such as messages, contact details, phone numbers, images, and video files, are recoverable from the smartphone device that is equipped with these mVoIP apps.

description: We discuss the magnetic excitations of well-ordered stripe and checkerboard phases, including the high energy magnetic excitations of recent interest and possible connections to the "resonance peak" in cuprate superconductors. Using a suitably parametrized Heisenberg model and spin wave theory, we study a variety of magnetically ordered configurations, including vertical and diagonal site- and bond-centered stripes and simple checkerboards. We calculate the expected neutron scattering intensities as a function of energy and momentum. At zero frequency, the satellite peaks of even square-wave stripes are suppressed by as much as a factor of 34 below the intensity of the main incommensurate peaks. We further find that at low energy, spin wave cones may not always be resolvable experimentally. Rather, the intensity as a function of position around the cone depends strongly on the coupling across the stripe domain walls. At intermediate energy, we find a saddlepoint at $(π,π)$ for a range of couplings, and discuss its possible connection to the "resonance peak" observed in neutron scattering experiments on cuprate superconductors. At high energy, various structures are possible as a function of coupling strength and configuration, including a high energy square-shaped continuum originally attributed to the quantum excitations of spin ladders. On the other hand, we find that simple checkerboard patterns are inconsistent with experimental results from neutron scattering.

The Issue of School Belonging: An Investigation into Resource Access and Classroom Environment at UT Austin

description: Colleges, the University of Texas at Austin (UT) included, have seen increasing numbers of students with non-dominant identities enroll in their programs. Some students hold more than one of these identities (e.g., ﬁrst-generation, LGBTQIA+), giving them unique experiences as the eﬀects of those identities must be considered together (e.g. the experience of a Black woman is diﬀerent from that of a queer Black woman). Because students with multiple non-dominant identities lack the social capital of individuals who have only one or no non-dominant identities (e.g., someone who is a White Christian English-speaking male), they have more diﬃcult pathways to achieving a sense of belonging on university campuses. That feeling of belonging is an important factor in academic achievement and overall rates of college completion. Resources and resource access are critical to give students the support they need to feel a sense of belonging. This thesis reviews two previous studies on school belonging: GenEquity (2020) and You Belong Here (2019). I also analyze data from working groups I helped conduct as part of an Actions that Promote Community Transformation (ACT) project on pedagogical caring. In going through these three studies, I break down reasons students do or do not access resources in the UT classroom. Three of the key reasons that emerged were ﬁnancial barriers (e.g., paying for healthcare, working a job), campus climate (e.g., racism, representation), and bureaucracy (e.g., policies, administration). I end the paper with a reﬂection on the ACT project and recommendations on how UT can help break down barriers to resource access to increase feelings of belonging. I recommend that UT consolidates resources, builds better structures to foster community, and improves pedagogical caring.

description: RESUMO

 

Considerar o processo de formação dos policiais no Brasil como relevante para o problema da liberdade, é mais que necessário, é urgente. Dada a relevância da questão, discutiremos um caso particular ocorrido em uma capacitação na Polícia Militar do Distrito Federal, cuja temática era a ética policial. Ao que as informações divulgadas sugerem, durante o curso de capacitação houve uma tentativa de justificar o falso problema de incompatibilidade entre os Direitos Humanos e a atividade policial através da Ética Utilitarista. Segundo consta no material didático apresentado, o emprego da tortura e a falsificação de provas seriam medidas aceitáveis, se resultassem na condenação de reincidentes. Isto posto, nosso objetivo é submeter à análise os argumentos apresentados na disciplina de formação dos Policiais Militares do Distrito Federal. Para isso, tomamos como referência os filósofos John Stuart Mill e Giorgio Agamben. O primeiro pensador será fundamental para questionarmos se a fundamentação teórica usada como justificativa para a tortura por parte dos policiais militares não encontra limites na própria teoria sugerida. O segundo, será incontornável para compreendermos por que o discurso que exalta a tortura é recepcionado por parte da sociedade.

description: We have observed H-alpha and [OIII] emission from eight of the most well defined Wolf-Rayet ring nebulae in the Galaxy. We find that in many cases the outermost edge of the [OIII] emission leads the H-alpha emission. We suggest that these offsets, when present, are due to the shock from the Wolf-Rayet bubble expanding into the circumstellar envelope. Thus, the details of the WR bubble morphology at H-alpha and [OIII] can then be used to better understand the physical condition and evolutionary stage of the nebulae around Wolf-Rayet stars, as well as place constraints on the nature of the stellar progenitor and its mass loss history.

description: Changes in atmospheric parameters, such as temperature, precipitation and relative humidity, as well as sea level rise, flooding and storm surge, can aggravate the chemical, biological and mechanical degradation of cultural heritage leading to loss of cultural value. Despite the growing body of research that examine the impacts of climate change on cultural heritage, mainly focused on producing climate change risk maps at the European scale, there is an absence of data, information and assessment methods available to incorporate climate change into preservation frameworks and management practices from government policy level down to the practice in the field. This study investigated the vulnerability and adaptation of cultural heritage sites in Europe. An indepth qualitative analysis of data collected through semi-structured interviews with academics, members of governmental institutions and managers of heritage sites experts in cultural heritage preservation was undertaken and complemented with the analysis of academic literature, management plans, policies and grey literature. The investigated peer-reviewed literature wassynthesized and depicted in diagrams that can help in the understanding of climate change impacts on cultural heritage. An integrated vulnerability assessment methodology was developed and tested in three European UNESCO World Heritage Sites (WHS) to help site managers and decision-makers to understand the vulnerabilities of cultural heritage to climate change impacts and to allow the incorporation ofclimate change risk assessment into the management of heritage sites. Furthermore, the perceptions of experts involved in the management and preservation of cultural heritage were investigated, specifically on their awareness and understanding of the impacts of climate change on heritage assets, on the adaptation of cultural heritage to climate change, and on the mitigation of climate change in the cultural heritage field, in Europe. This research highlights the lack of dissemination of the outcomes of scientific research to managers of cultural heritage in the context of vulnerability assessment and adaptation to climate change impacts. A better understanding of what needs to be provided and prioritized for adaptation to take place and in its strategic planning is derived from this analysis. Adapting cultural heritage to climate change can be possible only if strong actions both from research and government will be taken to overcome the barriers identified in this investigation.

description: Particle size dependent wall-loss rates vary widely between Teflon environmental chambers. For instance, the UCR/CE-CERT dual-90 m3 collapsible Teflon chambers (UCR collapsible chamber) measured particle wall-loss rates are relatively insensitive to particle size, while other chambers (e.g., Caltech, GaTech, UC Davis) exhibit a strong dependence of wall loss rates on particle size. Particle wall loss rates in the larger UCR collapsible chambers exceed those reported for some smaller volume chambers. The size-dependent particle wall-loss patterns in the absence of coagulation within the UCR collapsible chambers were experimentally characterized in this work using a monodisperse particle injection method. Electrostatic charges on chamber surfaces were found to dominate the particle deposition in the UCR collapsible chamber. Charged particles ∼50 nm in diameter decay much faster than charged 200 nm particles, but the overall decay enhancement by electrostatics was determined to be smaller for 50 nm particles due to kinetic charging limitations. Particles in the chamber, regardless of initial charge state, approached a chamber-specific charge steady-state, where the charge steady-state for smaller particles was driven by preferential loss of charged particles while the charge steady-state for larger particles was driven by bidirectional diffusion charging. Coagulation was found to be significant when high particle number loadings are present (e.g., 5 × 104 cm−3). Mitigation strategies are needed for environmental chambers susceptible to surface charging (e.g., UCR collapsible chambers) in order to lower the influence from electrostatics. The shape of the particle wall-loss pattern can be used to identify chambers driven by significant electrostatic particle wall-loss.
Particle number concentrations over Europe in 2030: the role of emissions and new particle formation

description: The aerosol particle number concentration is a key parameter when estimating impacts of aerosol particles on climate and human health. We use a three-dimensional chemical transport model with detailed microphysics, PMCAMx-UF, to simulate particle number concentrations over Europe in the year 2030, by applying emission scenarios for trace gases and primary aerosols. The scenarios are based on expected changes in anthropogenic emissions of sulfur dioxide, ammonia, nitrogen oxides, and primary aerosol particles with a diameter less than 2.5 μm (PM2.5) focusing on a photochemically active period, and the implications for other seasons are discussed.

For the baseline scenario, which represents a best estimate of the evolution of anthropogenic emissions in Europe, PMCAMx-UF predicts that the total particle number concentration (Ntot) will decrease by 30–70% between 2008 and 2030. The number concentration of particles larger than 100 nm (N100), a proxy for cloud condensation nuclei (CCN) concentration, is predicted to decrease by 40–70% during the same period. The predicted decrease in Ntot is mainly a result of reduced new particle formation due to the expected reduction in SO2 emissions, whereas the predicted decrease in N100 is a result of both decreasing condensational growth and reduced primary aerosol emissions. For larger emission reductions, PMCAMx-UF predicts reductions of 60–80% in both Ntotand N100 over Europe.

Sensitivity tests reveal that a reduction in SO2 emissions is far more efficient than any other emission reduction investigated, in reducing Ntot. For N100, emission reductions of both SO2 and PM2.5 contribute significantly to the reduced concentration, even though SO2 plays the dominant role once more. The impact of SO2 for both new particle formation and growth over Europe may be expected to be somewhat higher during the simulated period with high photochemical activity than during times of the year with less incoming solar radiation.

The predicted reductions in both Ntot and N100 between 2008 and 2030 in this study will likely reduce both the aerosol direct and indirect effects, and limit the damaging effects of aerosol particles on human health in Europe.

description: We discuss the unique spin evolution of the young X-ray pulsar PSR J0537-6910, a system in which the regular spin down is interrupted by glitches every few months. Drawing on the complete timing data from the Rossi X-ray Timing Explorer (RXTE, from 1999-2011), we argue that a trend in the inter-glitch behaviour points to an effective braking index close to $n=7$, much larger than expected. This value is interesting because it would accord with the neutron star spinning down due to gravitational waves from an unstable r-mode. We discuss to what extent this, admittedly speculative, scenario may be consistent and if the associated gravitational-wave signal would be within reach of ground based detectors. Our estimates suggest that one may, indeed, be able to use future observations to test the idea. Further precision timing would help enhance the achievable sensitivity and we advocate a joint observing campaign between the Neutron Star Interior Composition ExploreR (NICER) and the LIGO-Virgo network.

description: Atmospheric aerosol particles influence global climate as well as impair air quality through their effects on atmospheric visibility and human health. Ultrafine (<100 nm) particles often dominate aerosol numbers, and nucleation of atmospheric vapors is an important source of these particles. To have climatic relevance, however, the freshly nucleated particles need to grow in size. We combine observations from two continental sites (Egbert, Canada and Hyytiälä, Finland) to show that condensation of organic vapors is a crucial factor governing the lifetimes and climatic importance of the smallest atmospheric particles. We model the observed ultrafine aerosol growth with a simplified scheme approximating the condensing species as a mixture of effectively non-volatile and semi-volatile species, demonstrate that state-of-the-art organic gas-particle partitioning models fail to reproduce the observations, and propose a modeling approach that is consistent with the measurements. We find that roughly half of the mass of the condensing mass needs to be distributed proportional to the aerosol surface area (thus implying that the condensation is governed by gas-phase concentration rather than the equilibrium vapour pressure) to explain the observed aerosol growth. We demonstrate the large sensitivity of predicted number concentrations of cloud condensation nuclei (CCN) to these interactions between organic vapors and the smallest atmospheric nanoparticles – highlighting the need for representing this process in global climate models.

description: Transportation facilities are characterized by high population density and significant passenger turnover. These environments provide optimal conditions for the transmission of airborne microorganisms. We collected airborne microbial samples in transportation facilities in the Republic of Korea and characterize bacterial and fungal communities, and respiratory disease-associated viruses using qPCR, and derived regression equations. inhalation exposure levels were estimated based on the air concentration of microbiomes and the average weight and inhalation rate of Koreans. Microbial copy numbers were compared for significant differences based on facility type and season. The concentrations of bacteria (p < 0.001) and influenza A virus (p < 0.01) differed depending on the facility, whereas fungi showed variations based on the season (p < 0.001). Significant variations were noted, particularly in relation to the human rhinovirus, both in terms of seasonal patterns (p < 0.05) and between different facilities (p < 0.05). We found that human adenovirus (p < 0.01) and influenza A virus (p < 0.05) were positively influenced by particulate matter, while human rhinovirus was negatively affected by temperature (p < 0.05). Bacteria were positively influenced by CO2 (p < 0.001) and particulate matter (p < 0.01), whereas fungi were positively influenced by relative humidity (p < 0.001). The microbial inhalation exposure level among male children exceeded that among adult males (p < 0.05). Additionally, inhalation exposure to microbes was higher in trains than in train stations, which was attributed to the differences in usage times.

Graph Transformation Method for Calculating Waiting Times in Markov Chains

description: We describe an exact approach for calculating transition probabilities and waiting times in finite-state discrete-time Markov processes. All the states and the rules for transitions between them must be known in advance. We can then calculate averages over a given ensemble of paths for both additive and multiplicative properties in a non-stochastic and non-iterative fashion. In particular, we can calculate the mean first passage time between arbitrary groups of stationary points for discrete path sampling databases, and hence extract phenomenological rate constants. We present a number of examples to demonstrate the efficiency and robustness of this approach.

The CLIC Main Linac Accelerating Structure

Subjects: subject: Accelerator Physics (physics.acc-ph)
subject: FOS: Physical sciences

description: This paper outlines the RF design of the CLIC (Compact Linear Collider) 30 GHz main linac accelerating structure and gives the resulting longitudinal and transverse mode properties. The critical requirement for multibunch operation, that transverse wakefields be suppressed by two orders of magnitude within 0.7 ns (twenty fundamental mode cycles), has been demonstrated in a recent ASSET experiment. The feasibility of operating the structure at an accelerating gradient of 150 MV/m for 130 ns has yet to be demonstrated. Damage of the internal copper surfaces due to high electric fields or resulting from metal fatigue induced by cyclic surface heating effects are a major concern requiring further study.

description: As part of the 2016 public evaluation challenge on Detection and Classification of Acoustic Scenes and Events (DCASE 2016), the second task focused on evaluating sound event detection systems using synthetic mixtures of office sounds. This task, which follows the `Event Detection - Office Synthetic' task of DCASE 2013, studies the behaviour of tested algorithms when facing controlled levels of audio complexity with respect to background noise and polyphony/density, with the added benefit of a very accurate ground truth. This paper presents the task formulation, evaluation metrics, submitted systems, and provides a statistical analysis of the results achieved, with respect to various aspects of the evaluation dataset.

description: The ability to collect size-fractionated airborne particles that contain viable bacteria and fungi directly into liquid medium while also maintaining their viability is critical for assessing exposure risks. In this study, we present the BioCascade impactor, a novel device designed to collect airborne particles into liquid based on their aerodynamic diameter in three sequential stages (>9.74, 3.94–9.74, and 1.38–3.94 µm when operated at 8.5 L/min). Aerosol samples containing microorganisms—either Saccharomyces kudriavzevii or Micrococcus luteus, were used to evaluate the performance of the BioCascade (BC) paired with either the VIable Virus Aerosol Sampler (VIVAS) or a gelatin filter (GF) as stage 4 to collect particles <1.38 µm. Stages 2 and 3 collected the largest fractions of viable S. kudriavzevii when paired with VIVAS (0.468) and GF (0.519), respectively. Stage 3 collected the largest fraction of viable M. luteus particles in both BC + VIVAS (0.791) and BC + GF (0.950) configurations. The distribution function of viable microorganisms was consistent with the size distributions measured by the Aerodynamic Particle Sizer. Testing with both bioaerosol species confirmed no internal loss and no re-aerosolization occurred within the BC. Irrespective of the bioaerosol tested, stages 1, 3, and 4 maintained ≥80% of viability, while stage 2 maintained only 37% and 73% of viable S. kudriavzevii and M. luteus, respectively. The low viability that occurred in stage 2 warrants further investigation. Our work shows that the BC can efficiently size-classify and collect bioaerosols without re-aerosolization and effectively maintain the viability of collected microorganisms.
