Publisher: name: RomaTrE-Press
Year: 2019

description: Lo scopo del libro è quello di presentare i risultati di una survey che ha visto coinvolti i membri di alcune Law Enforcement Agency europee e un gruppo di esperti in materia di terrorismo e radicalizzazione che sono stati interrogati sul presente e il futuro della radicalizzazione violenta in Europa. Questa ricerca è stata condotta nell’ambito del progetto TRIVALENT. Dopo una descrizione del background teorico della ricerca e della metodologia utilizzata, saranno presentati i risultati delle interviste qualitative e del questionario Delphi.  La principale conclusione di questo studio è l’idea che la radicalizzazione e il terrorismo siano processi complessi e articolati in più livelli che coinvolgono sia i singoli individui sia le macro-strutture.

description: Utopia come ottimo luogo o non luogo, tradotto, questa volta, nei termini di una perfetta società delle macchine che riafferma la fiducia nell’assolutismo scientista e una posizione conservatrice fondata sull’immutabilità dell’umano? A cinquecento anni dall’utopia di Moro non vi è una via più duttile, capace di riflettere sulle trasformazioni future dell’umano? Quando apparve nel 1516 L’Utopia di Tommaso Moro voleva, secondo i più, esprimere il sogno rinascimentale di una società perfetta, in cui la cultura avrebbe dovuto regolare la vita degli uomini. Quella straordinaria ‘isola che non c’è’ è descritta ampiamente in uno spazio formata da cinquantaquattro città molto ben governate da abili magistrati e popolate da abitanti che lavorano poco, mai più di sei ore al giorno, producendo tutto ciò che serve per vivere, prelevando dai granai comuni secondo le proprie necessità. Individui tolleranti, pacifici, privi di avidità, gli abitanti di questa città ideale non hanno altri bisogni materiali, se non quelli che soddisfano facilmente nella vita comunitaria, facendo attenzione alle regole, persino a quelle dell’opportuna limitazione delle nascite. Il loro tempo libero è dedicato alla lettura, allo studio, alla musica, in termini contemporanei a realizzare l’ultima tappa dei bisogni di Maslow: la realizzazione di sé. Cosa resta di questo sogno straordinario nell’inconscio collettivo 500 anni dopo?

description: Quantitative understanding of the fracture toughness of metallic glasses, including the associated ductile-to-brittle transitions, is not yet available. Here we use a simple model of plastic deformation in glasses, coupled to an advanced Eulerian level set formulation for solving complex free boundary problems, to calculate the fracture toughness of metallic glasses as a function of the degree of structural relaxation corresponding to different annealing times near the glass temperature. Our main result indicates the existence of an elasto-plastic crack tip instability for sufficiently relaxed glasses, resulting in a marked drop in the toughness, which we interpret as a ductile-to-brittle transition similar to experimental observations.

description: Arctic regions are experiencing faster climate change than any other region in the world. Since the Arctic plays a critical role in the carbon cycle and strongly affects the thermal state of the surrounding permafrost, it is important to understand the impact of Arctic climate changes. This study investigates the climate and ecosystem changes of the Toolik Lake area in Alaska. Satellite remote sensing measurements and long-term baseline environmental and biological data from the Environmental Data Center (EDC) of the Toolik Field Station (TFS) were used to analyze this climate change and its impact on ecosystems. Land surface temperature (LST) data from the Terra/MODIS satellite remote sensing measurements show significant warming of the Toolik lake area in the past two decades, with an increasing trend of 1.049K/decade and 1.186K/decade for daytime and nighttime LST respectively. MODIS NDVI data during the summer season also shows a significant greening trend. EDC field observations show that air temperature above the Toolik lake has an increasing trend of 0.6762K/Decade from 1988 to the present, and 0.8598K/decade from 2000 to present, indicating that there has been faster warming in the past two decades. The thawing times of the Toolik Lake and the inlet river are becoming earlier, and the freezing times of the Toolik Lake and the inlet river are becoming later, causing the ice-free period of the lake to increase significantly. These changes have considerable impacts on local and regional ecosystems; for example, the first seen times of the Arctic ground squirrel around the study area are becoming earlier, and the hibernation periods are becoming shorter, as shown from the EDC field survey data. This study confirmed the rapid warming of Arctic regions and showed changes in the Toolik Lake ecosystem caused by climate change. In future research, these methods can be applied to other regions near the Arctic to gain further insight into changes in the Arctic regions caused by climate change.

description: Aims. Excitation of far-infrared and submillimetric molecular lines may originate from nonreactive collisions, chemical formation, or far infrared, near-infrared, and optical fluorescences. As a template, we investigate the impact of each of these processes on the excitation of the methylidyne cation CH+ and on the intensities of its rotational transitions recently detected in emission in dense photodissociation regions (PDRs) and in planetary nebulae. Methods. We have developed a nonlocal thermodynamic equilibrium (non-LTE) excitation model that includes the entire energy structure of CH+, i.e. taking into account the pumping of its vibrational and bound and unbound electronic states by near-infrared and optical photons. The model includes the theoretical cross-sections of nonreactive collisions with H, H2, He, and e-, and a Boltzmann distribution is used to describe the probability of populating the excited levels of CH+ during its chemical formation by hydrogenation of C+. To confirm our results we also performed an extensive analytical study, which we use to predict the main excitation process of several diatomic molecules, namely HF, HCl, SiO, CS, and CO. Results. At densities nH = 10^4 cm-3, the excitation of the rotational levels of CH+ is dominated by the radiative pumping of its electronic, vibrational, and rotational states if the intensities of the radiation field at \sim 0.4, \sim 4, and \sim 300 \mum are stronger than 10^5, 10^8, and 10^4 times those of the local interstellar radiation field (ISRF). Below these values, the chemical pumping is the dominant source of excitation of the J > 1 levels, even at high kinetic temperatures (\sim 1000 K). The far-infrared emission lines of CH+ observed in the Orion Bar and the NGC 7027 PDRs are consistent with the predictions of our excitation model assuming an incident far-ultraviolet (FUV) radiation field of \sim 3 \times 10^4 (in Draine's unit) and densities of \sim 5 \times 10^4 and \sim 2 \times 10^5 cm-3. In the case of NGC 7027, the estimate of the density is 10 to 100 times lower than those deduced by traditional excitation codes. Applying our model to other X1Σ+ ground state diatomic molecules, we find that HF, and SiO and HCl are the species the most sensitive to the radiative pumping of their vibrational and bound electronic states. In both cases, the minimal near-infrared and optical/UV radiation field intensities required to modify their rotational level populations are \sim 10^3 times those of the local ISRF at densities nH = 10^4 cm-3. All these results point towards interstellar and circumstellar media with densities lower than previously established and cast doubts on the clumpiness of well-studied molecular clouds.

A Study of California Drought and Wildland Fires Using Satellite Remote Sensing Measurements

Year: 2022

description: With climate change increasing global temperatures, the threat of wildland fires has become more prevalent because of the dry and hot weather conditions. Knowledge of how and when wildland fires occur can help mitigate their disastrous effects. This project aims to investigate if precipitation trends in California can help scientists understand the patterns of these fires in that state. In this study, we analyzed wildland fire events in California from 2002 to 2019 and satellite remote sensing measurements of monthly precipitation from the NASA Giovanni system. Monthly precipitation anomaly time series was generated to evaluate the dry conditions in California. Compared with records of wildland fires in California collected from the National Interagency Fire Center, precipitation anomalies during fire season show remarkable connections with annual burned areas. In California, the peak fire season is from August to December, so precipitation anomaly time series of these five months in each year was generated for quantitative assessment. Regression analysis shows a moderate negative correlation between monthly precipitation anomaly during peak fire season and the area burned by wildland fires. The correlation suggests a link between precipitation and the damage caused by wildland fires in California. Further investigation into this topic may develop a method for predicting the area of wildland fire damage based on precipitation forecasting from climate models, providing decision supports for government agencies to prepare accordingly.

description: The clumping of massive star winds is an established paradigm, which is confirmed by multiple lines of evidence and is supported by stellar wind theory. We use the results from time-dependent hydrodynamical models of the instability in the line-driven wind of a massive supergiant star to derive the time-dependent accretion rate on to a compact object in the Bondi-Hoyle-Lyttleton approximation. The strong density and velocity fluctuations in the wind result in strong variability of the synthetic X-ray light curves. Photoionization of inhomogeneous winds is different from the photoinization of smooth winds. The degree of ionization is affected by the wind clumping. The wind clumping must also be taken into account when comparing the observed and model spectra of the photoionized stellar wind.

description: Agent-based simulations play a prominent role in guiding critical decision-making to aid in the COVID-19 pandemic. However, many fall short by treating point of interests (POIs) as identical, generic locations in which the virus may spread, relying on the assumption that all POIs receive a relatively equal number of visiting agents per day and that each agent has an equal chance of visiting any given POI. In light of this, we propose a novel COVID-19 simulation using Latent Dirichlet Allocation (LDA) to model agent visits to POIs by treating POIs as “words” and agent home census block groups (CBGs) as “documents”. LDA provides “topics” of CBGs from which a similar proportion of agents visit specific POIs. This preserves the statistical relationship between agent home CBGs and POI visits, allowing us to simulate agent visits to given POIs based on the LDA topic distribution of their home CBG. Using agent and POI data provided by SafeGraph Inc. for Fairfax County, Virginia, our simulation forecasts that mandating a 10-day quarantine after symptom onset would have had the potential to decrease the peak number of incident cases per day by 21.3% and delay the date of the peak by 13% compared to a case of complete non-intervention. Our simulation further shows that mandating mask usage in addition to a 10-day quarantine after symptom onset would have had the potential to decrease the peak number of incident cases per day by 67.5% and delay the date of the peak by 183% compared to complete non-intervention. This study contributes strong evidence to reinforce the notion that government interventions such as mask mandates have the potential to drastically reduce the number of infections and flatten the curve while introducing a novel method of LDA agent-based simulation.

description: The U.S. recycling rate has dramatically improved from 6.4% to 35.1% between 1960 and 2017. However, for the past decade, it has been stagnant at around 34 percent. In fact, according to a 2017 report by Eunomia and the European Environmental Bureau, the U.S. was ranked 27th worldwide in recycling rates. Prior research has illustrated a lack of public participation and insufficient information about the best recycling practices as part of the reasons for the stagnant recycling rate. Furthermore, there is generally limited research on recycling education programs in the United States. This study thus analyzes the role of recycling education programs on recycling rates in order to determine whether environmental education is an integral strategy to increase recycling rates. By relying on the U.S. EPA (Environmental Protection Agency)’s database on Environmental Education Grants, we created a database of recycling education projects by using the keyword search. This study found that recycling education only accounts for 11% of environmental literacy programs and has steadily decreased over time. We also found that the U.S. EPA funded recycling projects are positively related to population size and the number of landfill sites in each state using OLS regression analysis. The findings illustrate the imminent need for expanding public expenditures on more recycling education programs, which will improve recycling awareness, contribute to higher recycling rates, and ultimately lead to the creation of a circular economy.

description: *First Co-Authors The health and survival of global coral reef ecosystems are threatened by anthropogenic stressors including climate change, coastal pollution, dredging, overfishing, tourism, and disease. Marine Protected Areas (MPAs) are a management strategy used to protect coral reefs through varied limitations on human use; however, some research indicates that MPAs are not effective in mitigating the proliferation of coral disease. To determine whether MPAs are an effective coral reef protection tool with regard to disease, we performed a meta-analysis using published data to compare coral disease prevalence inside and outside MPAs. We extracted 33 total papers from 8 databases, and analyzed 3 studies after applying selection criteria. Preliminary forest plot results show that there is a positive mean difference between disease prevalence inside versus outside MPAs. The data show that MPAs may be slightly effective at protecting corals from disease, however other management strategies addressing the root causes of coral disease outbreaks, such as water pollution and climate change, which are not addressed directly by most MPAs, may be more effective.

description: Population synthesis is a process to create statistically realistic populations and households with characteristics that resemble a real population. Due to the many complex interactions in current urban societies, many digital twins of urban environments are developed using population synthesis which can imitate the aggregate population data as well as at the level of individuals for a certain region. A common deterministic technique used for generating this population is Iterative Proportional Fitting (IPF), and two probabilistic techniques are Conditional Probabilities (CP) and Simulated Annealing (SA). We aim to compare the relative performance of these techniques with the creation of a digital twin of Fairfax County in Virginia. The performance is evaluated using the total absolute error between population characteristics from the synthetic population to the aggregate population data provided by the American Community Survey (ACS) data from 2018 per census block group. Our results indicate that IPF and CP outperforms SA on time constraints as well as accuracy with generating a synthetic population in Fairfax County due to the computational intensiveness of SA. CP slightly outperforms IPF within similar time constraints due to a small sample size and rounding errors induced by IPF.

description: It is often claimed that there is not only one, but two different types of solar dynamos: the one that is responsible for the appearance of sunspots and the 11-yr cycle, frequently referred to as the "global dynamo", and a statistically time-invariant dynamo, generally referred to as the "local dynamo", which is supposed to be responsible for the ubiquitous magnetic structuring observed at small scales. Here we examine the relative contributions of these two qualitatively different dynamos to the small-scale magnetic flux, with the following conclusion: The local dynamo does not play a significant role at any of the spatially resolved scales, nearly all the small-scale flux, including the flux revealed by Hinode, is supplied by the global dynamo. This conclusion is reached by careful determination of the Sun's noise-corrected basal magnetic flux density while making use of a flux cancellation function determined from Hinode data. The only allowed range where there may be substantial or even dominating contributions from a local dynamo seems to be the scales below about 10 km, as suggested by observations of the Hanle depolarization effect in atomic spectral lines. To determine the fraction of the Hanle depolarization that may be due to the action of a local dynamo, a synoptic program is being initiated at IRSOL (Istituto Ricerche Solari Locarno).

description: Research on international conflict has previously focused on explaining events in terms of their stages such as the onset or escalation of major crises. Recently, however, global conflict modeling has received growing attention. Predictions of violent events, in particular, have been increasingly accurate using various methods ranging from expert knowledge to quantitative methods and conflict forecasting systems. The DARPA Integrated Crisis Early Warning System (ICEWS) is an effort to apply computational social science models to dynamic data sources to produce a coherent event dataset that enables actionable forecasts of foreign country stability. While international crisis forecasting is becoming increasingly prevalent using the ICEWS event data, little research exists on the development of feature optimization techniques to train machine learning-enabled conflict forecasting systems. In this project, we propose a methodology to predict future conflict behavior through feature optimization with the ICEWS event data. We performed various time-series analyses on the ICEWS event data in order to develop features from its most meaningful crisis indicators. Through an investigation of Russian conflict behavior patterns with former Soviet Union countries, we used machine learning to produce highly accurate forecasts for Russian crises one month in advance. For future work, we hope to create a more generalized early crisis detection system using data from every country in the ICEWS event dataset.

description: Die Energiewende und die Elektrifizierung von Sektoren (z. B. Wärme- und Verkehrssektor) werden politisch und gesellschaftlich weiter forciert. Für die elektrische Energieversorgung bedeutet dies einen Paradigmenwechsel. Smart Grid Lösungen bzw. Automatisierungslösungen stellen dabei eine kosteneffiziente und zukunftsfähige Möglichkeit dar, welche insbesondere die stark betroffene Niederspannungsebene ertüchtigt. Aus diesem Grund befasst sich diese Dissertation mit der Weiterentwicklung eines Systems zur Automatisierung von Niederspannungsnetzen, sodass zum einen der Installationsaufwand reduziert und zum anderen adaptiv auf die sich im Niederspannungsnetz einstellenden Veränderungen (z. B. durch die Integration von Photovoltaikanlagen und Ladeinfrastruktur) reagiert werden kann. Die Weiterentwicklungen dürfen dabei die Robustheit des Systems zur Automatisierung von Niederspannungsnetzen nicht beeinflussen. Somit werden in dieser Arbeit drei Funktionen dargestellt, welche die Hauptaufgaben eines „Smart Grids“ (Überwachung des Netzzustandes und Regelung des Netzzustandes in Echtzeit) ergänzen. Die Funktionen ermöglichen eine Validierung von Parametern, eine Bedarfsdetektion von Aktorflexibilität zur Regelung des Netzzustandes und eine Interaktion zwischen den Systemen der Mittel- und Niederspannungsautomatisierung in Echtzeit. Alle drei Funktionen sind in einer dezentralen Systemarchitektur auf Feldgeräten implementiert, welche eine begrenzte Rechen- und Speicherkapazität bereitstellen. Für diese Implementierung wird die Sensitivitätsanalyse als Substitution einer konventionellen Leistungsflussberechnung vorgestellt und auf die Anforderungen des Systems zur Automatisierung von Niederspannungsnetzen angepasst. Erst durch die in der Arbeit dargestellte Substitution und Verbesserung der Berechnungsgrundlage, ist die Implementierung in die Systemarchitektur möglich. Eine erfolgreiche Implementierung muss stets durch diverse Validierungen sichergestellt werden, sodass diese Arbeit ein simultanes und sukzessives Validierungskonzept dazu bereitstellt. Das entwickelte Validierungskonzept wird in dieser Arbeit für die Bewertung des Systems zur Automatisierung von Niederspannungsnetzen genutzt und prägnante Labor- und Feldtestergebnisse werden dargestellt. Diese Validierung stellt die erfolgreiche Weiterentwicklung dar, welche eine adaptive, aufwandsminimale, fehlerrobuste und zukunftsfähige Automatisierung von Niederspannungsnetzen ermöglicht.

description: Different soils show different nonlinear stress-strain patterns. Hence, it is difficultto  come  up  with  a  general  model  to  predict  these  shapes.  This  study  investigated  the  suitability  of  the  DHI  model  which  was  not  originally  formulated  for  geomaterials.  This  model  was  applied  to  different  loading  cycles  of  various  types  of  soils  and  the  model’s variables were optimized using nonlinear generalized reduced gradient (GRG) method. Up to five hysteresis springs were considered in the study. The computed error criteria indicated that the  DHI  model  approximated  the  nonlinear  hysteresis  shapes  appropriately  and  using  three  hysteresis  springs  presented  the  best  estimation  for  almost  all  cases.  In  addition,  this  model  approximated the initial loading cycles better than the final ones.

description: In this work, the phenomenon of formation of localised electrostatic waves (ESW) or soliton is considered in a warm magnetoplasma with the possibility of non-thermal electron distribution. The parameter regime considered here is relevant in case of magnetospheric plasmas. We show that deviation from a usual relaxed Maxwellian distribution of the electron population has a significant bearing in the allowed parameter regime, where these ESWs can be found. We further consider the presence of more than one electron temperature, which is inspired by recent space-based observations[key-2].

description: Amidst the COVID-19 pandemic, there have been significant efforts to develop simulation models to forecast trends of the virus. However, there remains a lack of analysis between such models, resulting in uncertainty among policy-makers and the general population about the virus’s future trends. This study develops two ensemble learning approaches of classification and regression to find agreement between prominent COVID-19 death forecast models for more comprehensive policy-making and judgement. To standardize uneven forecasts, we test imputation and normalization methods including, but not limited to linear interpolation, tensor factorization, and generative adversarial networks. We show that piecewise linear interpolation outperforms more complex approaches due their inability to exploit temporal autocorrelations. For classification, we apply a principal component analysis to extract latent feature representations. We employ the partitioning-around-medoids algorithm with a Manhattan distance metric in a k-medoids problem to classify the extracted representations into interpretable clusters. We name each medoid as a representative and quantify the range of deviation of other cluster members from the representative to easily interpret each cluster as a whole. For regression, we train a deep neural network (DNN) to predict ground truth COVID-19 deaths from a sliding window input of other models’ aggregated predictions. We show that the DNN can adequately forecast the ground truth based only on these aggregated predictions while remaining robust against outliers, reaching a mean absolute error of under 200 when forecasting incidental deaths for a single day a week into the future. Our ensemble models contribute a comprehensive method to analyze various consensus between current COVID-19 simulation models.

description: Experimental   creep   curves   and   long-term   strength   curves   for viscoelastic compressible materials have been obtained at room temperature for a wide range of stresses. The  residual  density  change  (loosening)  of  the  material  is  considered  as  the  main  damage  factor. A modified creep equation for the loosening medium is proposed, which can describe the second and third regions of the creep curve.  Based on proposed equation the criterion of long-term strength is formulated. It is shown that in the region of relatively high stresses and under the  assumption  of  incompressibility  of  the  material,  this  criterion  coincides  with  the  known Hoff law of viscous fracture.

description: A portable synchrotron MBE system is designed and applied for in situ investigations. The growth chamber is equipped with all the standard MBE components such as effusion cells with shutters, main shutter, cooling shroud, manipulator, RHEED setup and pressure gauges. The characteristic feature of the system is the beryllium windows which are used for in situ x-ray measurements. An UHV sample transfer case allows in-vacuo transfer of samples prepared elsewhere. We describe the system design and demonstrate it's performance by investigating the annealing process of buried InGaAs self organized quantum dots.

description: Cathelicidins are a family of host defense peptides that play a large role in the innate immune system of many vertebrates, including humans, birds, and bats. This study looks at cathelicidins present in Chiroptera, commonly known as bats, because they have the ability to host viral pathogens that can cause significant human disease. Of the 30 cathelicidin sequences reported in the NCBI database, 27 unique cathelicidin remained after duplicate sequences were removed. Similarly, 6 unique sequences were compiled from the 7 sequences reported in UniProt; however, these analyses did not yield the active regions of the peptides. Using the multiple sequence alignment tool in Jalview, the combined 33 sequences were aligned and qualitatively analyzed to establish similarities in their respective sequences. Then, ScanProsite, from Prosite, confirmed the presence of the cathelicidin signature in a number of sequences by comparing them to the Prosite motif collection. The amino acid residues C-terminal to the cathelicidin signature were identified as the active amino acid regions. The predicted active regions were evaluated through the Antimicrobial Peptide Database, as well as CAMP R3. Both sites gave a strong indication that the peptides present antimicrobial properties. Through these analyses, 11 sequences from NCBI and 6 sequences from UniProt were identified to have active antimicrobial regions. Identifying the active regions of cathelicidins is crucial to their application as resources for therapeutic development.

Cleavage Site Prediction for Activation of Avian Cathelicidin Peptides

description: The innate immune systems of multicellular organisms contain host defense peptides that, through varied mechanisms, help defend against viruses. Cathelicidins, a class of host defense peptides, have a signal, a cathelin, and a C-terminal active domain. The cathelin domain is highly conserved, while the active domain varies greatly. We anticipate that better understanding how animals’ innate immune systems fight viruses will provide insights into new therapeutics. Birds, in particular, are associated with potential viral pathogens. As the number of sequenced avian cathelicidin peptides increases, we hypothesized that through bioinformatics we can predict the active peptide domain of sequenced avian cathelicidin precursor proteins. We compiled 61 avian cathelicidin candidate sequences from the NCBI database and an additional 18 from Uniprot, and we used multiple sequence alignment to establish a consensus sequence. The middle region of the sequences displayed high levels of consensus, while near the C-terminal region displayed much greater sequence variation. The sequences were submitted for analysis by the DRAMP antimicrobial peptide database, which identified likely active regions in 6 of 79 sequences submitted. The alignment of 5 of the 6 sequences suggests a conserved cleavage site in their precursor proteins. This predicted cleavage site was applied to the remaining 73 precursor candidates to identify their mature cathelicidin sequences. Analysis of these sequences with CAMP R3 predicted the majority to be antimicrobial.
