description: Traditional routes to Charge-Density-Wave in transition metal dichalcogenides, relying on Fermi surface nesting or Jahn-Teller instabilities have recently been brought into question. While this calls for exploration of alternative views, paucity of theoretical guidance sustains lively controversy on the origin of, and interplay between CDW and superconductive orders in transition metal dichalcogenides. Here, we explore a preformed excitonic liquid route, heavily supplemented by modern correlated electronic structure calculations, to an excitonic-CDW order in 1T-TiSe$_{2}$. We show that orbital-selective dynamical localisation arising from preformed excitonic liquid correlations is somewhat reminiscent to states proposed for $d$- and $f$-band quantum criticality at the border of magnetism. Excellent quantitative explication of a wide range of spectral and transport responses in both normal and CDW phases provides strong support for our scenario, and suggests that soft excitonic liquid fluctuations mediate superconductivity in a broad class of transition metal dichalcogenides on the border of CDW. This brings the transition metal dichalcogenides closer to the bad actors in $d$- and $f$-band systems, where anomalously soft fluctuations of electronic origin are believed to mediate unconventional superconductivity on the border of magnetism.

description: Η ανησυχία τoυ ανθρώπου για την διατροφή μπορεί να παρατηρηθεί από τα αρχαία κιόλας χρόνια, όταν ο Ιπποκράτης ήδη από το 400 π.Χ. είχε αναφέρει το γνωστό «Η τροφή σου να είναι το φάρμακό σου και το φάρμακό σου να είναι η τροφή σου». Οι σημερινές κοινωνίες χαρακτηρίζονται από τον υψηλό ρυθμό ταχύτητας, με αποτέλεσμα την ολοένα και περισσότερη αύξηση ασθενειών, με τον σακχαρώδη διαβήτη και το καρκίνο να αποτελούν μια μεγάλη κατηγορία αυτών. Οι περιπτώσεις αυτές, αποτελούν νόσους με αρκετά μεγάλο επιπολασμό στον πληθυσμό, οι οποίες έχουν μελετηθεί τόσο σε μοριακό όσο και σε γενετικό επίπεδο. Και στις δυο ασθένειες τα ποσοστά θανάτου αλλά και ο αριθμός των προσβεβλημένων ατόμων, συνεχώς αυξάνουν με ραγδαίο ρυθμό. Ως εκ τούτου, οι πολυπαραγοντικές αυτές παθήσεις έχουν μελετηθεί εκτενώς, με την επίδραση της διατροφής και των γονιδίων, να αποτελούν τους πλέον κύριους λόγους για την εμφάνιση τους. Ο σκοπός της εργασίας, είναι η μελέτη κυρίως αυτών των δυο ασθενειών και η αλληλεπίδραση τους με τις διατροφικές συνήθειες των ανθρώπων σε παγκόσμιο επίπεδο, καθώς και με τις μεταλλάξεις των γονιδίων που τις προκαλούν. Όσον αφορά το σακχαρώδη διαβήτη που πλέον χαρακτηρίζεται ως η επιδημία του 21ου αιώνα, έχουν αναλυθεί τα σημαντικότερα γονίδια τόσο για τον σακχαρώδη διαβήτη τύπου Ι όσον και για τον τύπο ΙΙ, αν και τα ευρήματα του πρώτου είναι εμφανώς λιγότερα. Για την ασθένεια του καρκίνου, τα γονίδια που μελετήθηκαν είναι πολυάριθμα εφόσον μεταλλάξεις μπορούν να εντοπιστούν σε κάθε ζωτικό όργανο του ανθρώπινου σώματος. Οι διατροφικές συνήθειες και η σωματική άσκηση εμφανίζουν μεγάλο αντίκτυπο στην εμφάνιση των συγκεκριμένων ασθενειών. Κατευθυντήριες γραμμές και διατροφικά πρότυπα έχουν δημιουργηθεί και περιλαμβάνουν τροφές και θρεπτικά συστατικά που πρέπει να συμπεριλαμβάνονται σε κάθε διαιτολόγιο με βασικό σκοπό όχι μόνο τη πρόληψη αλλά και σε ορισμένες περιπτώσεις για την εξάλειψη των μελετώμενων νόσων. Επιπλέον, έχει εξεταστεί η αλληλεπίδραση ορισμένων θρεπτικών συστατικών με τα γονίδια της εκάστοτε ασθένειας, με τα αποτελέσματα να δείχνουν πως μια τροποποίηση στη ποσότητα των παραπάνω, είναι ικανή να αποφέρει τόσο θετικά όσο και αρνητικά αποτελέσματα. Τέλος, έχει γίνει αναφορά σε ορισμένες διατροφές όπως η μεσογειακή και η χορτοφαγική, με τα αποτελέσματα τους να κρίνουν τη σημαντικότητα της επίδρασης τους.

Determination of alkylbenzene sulfonates in water by using phase extraction and vapor-phase esterification gas chromatography
Creators: name: Eivazi, Parviz
Publisher: name: University of Nevada, Las Vegas
Year: 1981

description: Linear Alkylbenzene Sulfonates (LAS) are an important class of anionic surfactants used as detergents for both industrial and domestic applications. LAS are released to the environment from waste water treatment, leaking septic tanks, and run off. LAS compounds are biologically reactive and have been found to have estrogenic properties. Despite the common occurrence of these compounds they are difficult to analyze in water and waste water. Colorimetric assay such as EPA 425.1 is simple to perform, but are not specific for LAS. Reversed phase liquid chromatography has been utilized for the analysis of these compounds but this method does not give good resolution of LAS components. Gas chromatography (GC) of LAS esters provides a high resolution separation of LAS compounds but the ester derivatives are not easy to quantitatively synthesize; Recently, some promising methods utilizing tetrabutylammonium ion pairs to esterify LAS during GC injection have been published. Vapor phase derivatization using tetrabutylammonium bisulfate (TBA) ion pair was investigated using a pyrolyzer type GC injector. The temperature dependence of this vapor phase derivatization and ester formation using TBA ion-pair reagent has been investigated. In this study an ion pair derivatization (flash-heater esterification) method using trialkylsulfonium and dimethylarylsulfonium cations instead of the tetrabutylammonium cation (TBA) has been developed. The synthesis of sulfonium cations has also been investigated. This project has produced a new analytical method for LAS using trialkylsulfonium and dimethylarylsulfonium cations. The method has utilized reversed phase extraction (SPE) methods for isolating extracting LAS from water. The LAS are then allowed to interact with the sulfonium salt, to form a sulfonium-LAS ion pair, which is then injected into a gas chromatograph to effect esterification and separation. Preliminary results from an analysis of water from Lake Mead are reported.

description: Fluid-mediated mass transfer in subduction zones is crucial for chemical cycling on Earth. Particularly little is, however, known about such processes at shallow subduction levels. We used thermodynamic models to reproduce the metamorphic history of ocean island basalt (OIB) clasts recovered from the Mariana forearc during IODP Expedition 366. The OIBs were subducted to ~30 km depth, metamorphosed/metasomatized, and subsequently recycled to the seafloor via mud volcanism (Fryer et al., 2020). The rocks exhibit K2O contents (median = 4.6 wt.%) and H2O (median = 5.3 wt.%) much higher than OIBs situated on the Pacific plate (Deng et al., 2021), suggesting that these have been added during subduction. This interpretation is in line with the presence of abundant phengite in the samples. Additionally, mass balance calculations point to the addition of SiO2, and high Cs, Rb, Th, and U concentrations imply an uptake whereas low Ba and Sr contents indicate the removal of trace elements. We show that the metasomatic change in composition and the formation of phengite can be explained by (i) the dehydration of altered oceanic crust releasing K2O-rich fluids and (ii) the subsequent reaction of such fluids with OIB. These processes are predicted to initiate at temperatures of <200°C and pressures of <5 kbar. Our study provides direct evidence for fluid–rock interactions and metasomatism in an active subduction zone. We demonstrate that mass transfer from subducted oceanic crust initiates at low pressure/temperature conditions. Subducted volcanics can hence undergo significant compositional changes even at shallow depths.

description: Bulk metallic glasses (BMGs) are produced by rapidly thermally quenching supercooled liquid metal alloys below the glass transition temperature at rates much faster than the critical cooling rate R_c below which crystallization occurs. The glass-forming ability of BMGs increases with decreasing R_c, and thus good glass-formers possess small values of R_c. We perform molecular dynamics simulations of binary Lennard-Jones (LJ) mixtures to quantify how key parameters, such as the stoichiometry, particle size difference, attraction strength, and heat of mixing, influence the glass-formability of model BMGs. For binary LJ mixtures, we find that the best glass-forming mixtures possess atomic size ratios (small to large) less than 0.92 and stoichiometries near 50:50 by number. In addition, weaker attractive interactions between the smaller atoms facilitate glass formation, whereas negative heats of mixing (in the experimentally relevant regime) do not change R_c significantly. These studies represent a first step in the development of computational methods for quantitatively predicting glass-formability.

description: Silicon is viewed as an excellent electrode material for lithium batteries due to its high lithium storage capacity. Various Si nano-structures, such as Si nanowires, have performed well as lithium battery anodes and have opened up exciting opportunities for the use of Si in energy storage devices. The mechanism of lithium insertion and the interaction between Li and the Si electrode must be understood at the atomic level; this understanding can be achieved by first-principles simulation. Here, first-principles computations of lithiation in silicon electrodes are reviewed. The review focuses on three aspects: the various properties of bulk Li-Si compounds with different Li concentrations, the electronic structure of Si nanowires and Li insertion behavior in Si nanowires, and the dynamic lithiation process at the Li/Si interface. Potential study directions in this research field and difficulties that the field still faces are discussed at the end.

description: This paper links the field of potential theory -- i.e. the Dirichlet and Neumann problems for the heat and Laplace equation -- to that of the Feynman path integral, by postulating that the potential is equal to plus/minus the Laplacian of the indicator of the domain D. The Laplacian of the indicator is a generalized function: it is the d-dimensional analogue of the Dirac delta'-function. This function has -- according to the author's best knowledge -- not formally been defined before. We show, first, that the path integral's perturbation series (or Born series) matches the classical single and double boundary layer series of potential theory, thereby connecting two hitherto unrelated fields. Second, we show that the perturbation series is valid for all domains D that allow Green's theorem (i.e. with a finite number of corners, edges and cusps), thereby expanding the classical applicability of boundary layers. Third, we show that the minus (plus) in the potential holds for the Dirichlet (Neumann) boundary condition; showing for the first time a particularly close connection between these two classical problems. Fourth, we demonstrate that the perturbation series of the path integral converges in a monotone/alternating fashion, depending on the convexity/concavity of the domain. We also discuss the third boundary problem (which poses Robin boundary conditions) and discuss an extension to moving domains.

The effect of movement velocity and eccentric contractions on the bilateral deficit
Creators: name: Dickin, D. Clark
Publisher: name: University of Nevada, Las Vegas
Year: 2005

description: This study was performed to examine the effects of movement velocity and eccentric contractions on the bilateral deficit. To accomplish this, 18 participants performed bilateral and unilateral contractions eccentrically and concentrically across 6 movement velocities (30, 60, 90, 120, 150, and 180{dollar}\sp\circ{dollar}/s). Repeated measures ANOVA's revealed that for both eccentric and concentric contractions, significant differences existed between bilateral and summed unilateral contractions; and at each of the six tested velocities. Further analyses revealed that the degree of the bilateral deficit increased as movement velocity increased. It is believed that the decreased tension developed during bilateral eccentric and concentric contractions, is attributed to incomplete activation of fast twitch muscle fibers recruited during unilateral contractions.

description: We extend the analysis of Chiba, Smith and Erickcek \cite{CSE} of Solar System constraints on $f(R)$ gravity to a class of nonminimally coupled (NMC) theories of gravity. These generalize $f(R)$ theories by replacing the action functional of General Relativity (GR) with a more general form involving two functions $f^1(R)$ and $f^2(R)$ of the Ricci scalar curvature $R$. While the function $f^1(R)$ is a nonlinear term in the action, analogous to $f(R)$ gravity, the function $f^2(R)$ yields a NMC between the matter Lagrangian density $\LL_m$ and the scalar curvature. The developed method allows for obtaining constraints on the admissible classes of functions $f^1(R)$ and $f^2(R)$, by requiring that predictions of NMC gravity are compatible with Solar System tests of gravity. We apply this method to a NMC model which accounts for the observed accelerated expansion of the Universe.

description: Spam SMS is unsolicited messages to users that are annoying and sometimes harmful. Spam fills the inbox with a multitude of ridiculous emails. They degrade our internet speed to a great extent and steal useful information like our contact details. Identifying these spammers and also spam content can be a hot topic of research and tedious tasks There are a lot of studies on email spam detection techniques. However, SMS spam detection is a comparatively new field, and a systematic literature survey in this area is insufficient. In this paper, we conduct a systematic literature review of SMS and E-mail spam detection techniques. In this paper, we applied machine learning algorithms and data mining techniques, and focus on the accuracy and precision of algorithms to classified spam and non-spam mails and message

This report synthesizes over 15 years of research (and 64 site-years of data) on water use, carbon assimilation, and associated ecosystem development on reclaimed oil-sands-mine sites and on non-mine reference sites. A key feature of this research is the use of eddy-covariance methods to make integrative measurements of ecosystem performance. This approach uses instruments mounted on towers above the vegetation canopy to take continuous measurements of the atmospheric products of ecosystem function, specifically water and carbon dioxide exchange.

description: From the time the first stars formed over 13 billion years ago to the present, star formation has had an unexpectedly dynamic history. At first, the star formation rate density increased dramatically, reaching a peak 10 billion years ago more than ten times the present day value. Observations of the initial rise in star formation remain difficult, poorly constraining it. Theoretical modeling has trouble predicting this history because of the difficulty in following the feedback of energy from stellar radiation and supernova explosions into the gas from which further stars form. Observations from the ground and space with the next generation of instruments should reveal the full history of star formation in the universe, while simulations appear poised to accurately predict the observed history.

description: The antiferromagnetic correlation plays an important role in high-T$_{c}$ superconductors. Considering this effect, the magnetic excitations in n-type cuprates near the optimal doping are studied within the spin density wave description. The magnetic excitations are commensurate in the low energy regime and further develop into spin wave-like dispersion at higher energy, well consistent with the inelastic neutron scattering measurements. We clearly demonstrate that the commensurability originates from the band splitting and Fermi surface topology. The commensurability is a normal state property, and has nothing to do with d-wave superconductivity. The distinct behaviors of magnetic excitation between the n-type and p-type cuprates are further discussed. Our results strongly suggest the essential role of antiferromagnetic correlations in the cuprates.

description: The panalpine project "DOVE" (Drilling Overdeepened Alpine Valleys), co-funded by the International Continental Scientific Drilling Program (ICDP), is drilling a series of overdeepened glacial troughs around the Alps that were formed by subglacial erosion during past glaciations. The sedimentary fill of these troughs, consisting of multiple stacked and nested glacial sequences, provides the best archives of when and where glaciers reached the Alpine forelands. The combined data from all DOVE sites comprising synchronous or asynchronous ice advances and ice extents in the different regions, will eventually provide a critical database to evaluate the various patterns in glacial-interglacial paleoclimates and landscape evolution back to the Mid-Pleistocene. In this context, we accomplished several seismic surveys at the Tannwald Basin and Basadingen Valley as well as the Lienz Basin. Deploying small-scale vibratory sources in vertical and horizontal orientations, we examined both P- and S-wave reflection imaging. We were able to image (1) the bedrock topography and (2) the interior of overdeepened valleys in high resolution in all investigated sites. Especially, the sedimentary succession and thickness of the deposits vary in detail across the sites. Even the infills of valleys in the same catchment area differ significantly (e.g. Tannwald Basin and Basadingen Valley in the Rhine Glacier arena). Nonetheless, foreland and intra-mountainous valleys show the same overall structure for each accumulation cycle (more or less from bottom to top: basal till, basin fines, fluvial deposits). As conclusion, a detailed seismic study of each overdeepened valley is mandatory for a comprehensive understanding of overdeepened structures.

description: We report on a hitherto unexplored application of squeezed light: for quantum-enhancement of mechanical transduction sensitivity in microcavity optomechanics. Using a toroidal silica microcavity, we experimentally demonstrate measurement of the transduced phase modulation signal with a sensitivity $-0.72(\pm 0.01)$\,dB below the shot noise level. This is achieved for resonant probing in the highly under-coupled regime, by preparing the probe in a weak coherent state with phase squeezed vacuum states at sideband frequencies.
An Augustinian analysis of the Comprehensive Test Ban Treaty
Creators: name: White, Jon McClendon
Publisher: name: University of Nevada, Las Vegas
Year: 2000

description: Applying the Christian principles of depraved human nature, expectation of detrimental behavior from irrational actors, and rational attempts to limit the destructiveness of war, Augustine would conclude that the declared nuclear weapons states have a moral obligation to prevent proliferation of nuclear weapons. Laws suitable to the needs of the times are the appropriate method for accomplishing this. The pending Comprehensive Test Ban Treaty (CTBT) is one such law. Because the CTBT bans all nuclear explosions and establishes an intrusive inspection scheme, it will have an impact on the U. S. Department of Energy (DoE). DoE should respond by participating in the new inspection organization, by interpreting findings resulting from inspections, and by continuing management of the Nevada Test Site. The CTBT may be efficacious in preventing nuclear weapons proliferation in the short term. Considering a longer-term perspective, a frightening prospect emerges as a result of an Augustinian assessment of human nature.

description: Aim of the study: Sialidases, also called neuraminidases, are enzymes that cleave terminal sialic acids from glycoconjugates. In humans and mice, lung fibrosis is associated with desialylation of glycoconjugates and upregulation of sialidases. There are four mammalian sialidases, and it is unclear when the four mammalian sialidases are elevated over the course of inflammatory and fibrotic responses, whether tissue resident and inflammatory cells express different sialidases, and if sialidases are differentially expressed in male and females. Materials and Methods: To determine the time course of sialidase expression and the identity of sialidase expressing cells, we used the bleomycin model of pulmonary fibrosis in mice to examine levels of sialidases during inflammation (days 3 − 10) and fibrosis (days 10 − 21). Results: Bleomycin aspiration increased sialidase NEU1 at days 14 and 21 in male mice and day 10 in female mice. NEU2 levels increased at day 7 in male and day 10 in female mice. NEU3 appears to have a biphasic response in male mice with increased levels at day 7 and then at days 14 and 21, whereas in female mice NEU3 levels increased over 21 days. In control mice, the sialidases were mainly expressed by EpCAM positive epithelial cells, but after bleomycin, epithelial cells, CD45 positive immune cells, and alveolar cells expressed NEU1, NEU2, and NEU3. Sialidase expression was higher in male compared to female mice. There was little expression of NEU4 in murine lung tissue. Conclusions: These results suggest that sialidases are dynamically expressed following bleomycin, that sialidases are differentially expressed in male and females, and that of the four sialidases only NEU3 upregulation is associated with fibrosis in both male and female mice.

description: The HARP and NA61/SHINE hadroproduction experiments as well as their implications for neutrino physics are discussed. HARP measurements have already been used for predictions of neutrino beams in K2K and Mini-BooNE/SciBooNE experiments and are also being used to improve the atmospheric neutrino flux predictions and to help in the optimization of neutrino factory and super-beam designs. First measurements released recently by the NA61/SHINE experiment are of significant importance for a precise prediction of the J-PARC neutrino beam used for the T2K experiment. Both HARP and NA61/SHINE experiments provide also a large amount of input for validation and tuning of hadron production models in Monte-Carlo generators.

Although greigite (Fe3S4) has been identified by magnetic experiments in the North Sea and Wytch Farm oilfields, it was not included in previous thermodynamic models. Multiple studies have outlined the conditions required for greigite preservation in nature: sulphur supply needs to be enough to form greigite but limited as to not proceed to form pyrite; total organic carbon content needs to be low as it can produce sulphides; there needs to be a high availability of reactive iron. This study uses thermodynamic modelling to help constrain the following: What is the optimum level of sulphur? How much available iron is required? At what temperatures is greigite stable? Answering these questions is the first step in determining how greigite can exist in hydrocarbon environments.
Digital storytelling in a Japanese university academic English course: Investigating the impact of a project-based language learning approach on students’ critical thinking and motivation

description: This single-case descriptive case study discusses the value of integrating a socially conscious project-based language learning (PBLL) digital storytelling (DST) project into a first-year Japanese university English for academic purposes (EAP) course. This thesis bridges an existing gap in the academic literature with improved understanding of digital narratives in an academic English context. The unique hybrid theoretical framework that is used to organize the study and scrutinize the data, namely the merger of Keller’s (1987, 2010) ARCS model of motivational design and Thomas and Lok’s (2015) critical thinking attributes model, can also be deployed by educators and materials makers to measure the motivational effectiveness and level of criticality in both ‘in-house’ instructional materials and ‘remixed’ resources. A qualitative case study methodology is utilized to analyse 63 student participants’ perceptions and experiences creating a socially conscious digital narrative in their EAP class. This thesis highlights how I successfully integrated a PBLL DST initiative into a content-driven EAP course. It also shows how English language learners’ digital competencies, motivation, and critical awareness of local and global sociocultural issues can be fostered through socially conscious multimodal projects. The results from the data analysis suggests that the participants generally held positive views about DST. However, I also discovered that elements such as social loafing, free riding, intragroup conflicts, problematic ICT issues, busy schedules, and time-crunch anxiety can have an adverse impact on students’ confidence and satisfaction conditions (Keller, 2010) in a DST project. The findings from this study will reverberate with both English as an international language (EIL) educators and research practitioners who would like to integrate a PBLL DST approach into their professional practice. My thesis challenges the widely accepted ‘digital native’ narrative and urges administrators to provide Japanese EIL students with more DST training opportunities and space for self-directed English language learning.

Water policy and theoretical models: Political, bureaucratic and class dynamics in a growth economy
Creators: name: De Vine, Kelly Michelle
Publisher: name: University of Nevada, Las Vegas
Year: 2001

description: Water Policy and Theoretical Models: Political, Bureaucratic and Class Dynamics in a Growth Economy explores the three major socio-political theories of the state and public policy: pluralism, elite/managerialism and class-dialecticism using a case study of a series of policy decisions and outcomes during the period from 1989 to 1995 related to the Las Vegas Valley Water District which serves Las Vegas, Nevada. This time period is important due to the unprecedented levels of population growth experienced in the Las Vegas Valley and due to the extreme scarcity of water resources. This case study explores the issues of popular politics, bureaucratic and elite organization and class imperatives as played out in the development of public water policy by the Las Vegas Valley Water District.

description: Formation of bodies near the deuterium-burning limit is considered by detailed numerical simulations according to the core-nucleated giant planet accretion scenario. The objects, with heavy-element cores in the range 5-30 Mearth, are assumed to accrete gas up to final masses of 10-15 Jupiter masses (Mjup). After the formation process, which lasts 1-5 Myr and which ends with a 'cold-start', low-entropy configuration, the bodies evolve at constant mass up to an age of several Gyr. Deuterium burning via proton capture is included in the calculation, and we determined the mass, M50, above which more than 50% of the initial deuterium is burned. This often-quoted borderline between giant planets and brown dwarfs is found to depend only slightly on parameters, such as core mass, stellar mass, formation location, solid surface density in the protoplanetary disk, disk viscosity, and dust opacity. The values for M50 fall in the range 11.6-13.6 Mjup, in agreement with previous determinations that do not take the formation process into account. For a given opacity law during the formation process, objects with higher core masses form more quickly. The result is higher entropy in the envelope at the completion of accretion, yielding lower values of M50. For masses above M50, during the deuterium-burning phase, objects expand and increase in luminosity by 1 to 3 orders of magnitude. Evolutionary tracks in the luminosity-versus-time diagram are compared with the observed position of the companion to Beta Pictoris.

description: CuxBi2Se3 has been proposed as a potential topological superconductor characterized by an odd-parity full bulk superconducting gap and zero-energy surface Andreev bound states (Majorana fermions). A consequence of such Majorana fermions is a peak in the zero-energy density of states which should lead to a persistent zero-bias-conductance-peak (ZBCP) in Andreev reflection (AR) or tunneling experiments. Here we employ a newly developed nanoscale AR spectroscopy method to study normal metal/superconductor (N-S) devices featuring CuxBi2Se3. The results show that a ZBCP can be tuned in or out from CuxBi2Se3 samples depending on the N-S barrier strength. While the appearance of ZBCP may be traced to different origins, its absence under finite barrier strength represents the absence of zero-energy Majorana fermions. The present observations thus call for a reexamination of the nature of the superconducting state in CuxBi2Se3.

Object identification for robotic applications using expert systems
Creators: name: Devarajan, Sureshkumar
Publisher: name: University of Nevada, Las Vegas
Year: 2003

description: The objective of this project is to develop an intelligent machine vision system for robotic applications to identify engineering tools and components; The imaging system consists of a 2-D digital camera and an ultrasonic range sensor attached to the robot end effector. Images of the target objects are captured by the camera. The images are then processed to remove the signal noise and to extract the object boundary; One major objective is to develop object feature descriptions which are invariant to scaling, translation or orientation. Efficient data reduction to an array of fewer than 25 numbers is achieved by the use of Fourier and regional descriptors. One of the array elements, object thickness, is determined directly from ultrasound range measurement; An expert system was successfully developed to classify the objects based on their descriptors. The knowledge base consists of rules for searching and pattern matching. The sensors were integrated to form a working vision system for the PUMA 500 robot. The performance of the vision system was tested with a set of objects. The expert system was found to be efficient, successful, and reliable in identifying all tested objects even with signal noise being present.

description: As we are moving towards the Internet of Things (IoT), the number of sensors deployed around the world is growing at a rapid pace. Market research has shown a significant growth of sensor deployments over the past decade and has predicted a significant increment of the growth rate in the future. These sensors continuously generate enormous amounts of data. However, in order to add value to raw sensor data we need to understand it. Collection, modelling, reasoning, and distribution of context in relation to sensor data plays critical role in this challenge. Context-aware computing has proven to be successful in understanding sensor data. In this paper, we survey context awareness from an IoT perspective. We present the necessary background by introducing the IoT paradigm and context-aware fundamentals at the beginning. Then we provide an in-depth analysis of context life cycle. We evaluate a subset of projects (50) which represent the majority of research and commercial solutions proposed in the field of context-aware computing conducted over the last decade (2001-2011) based on our own taxonomy. Finally, based on our evaluation, we highlight the lessons to be learnt from the past and some possible directions for future research. The survey addresses a broad range of techniques, methods, models, functionalities, systems, applications, and middleware solutions related to context awareness and IoT. Our goal is not only to analyse, compare and consolidate past research work but also to appreciate their findings and discuss their applicability towards the IoT.

Burned: Measuring the Effects of Wildfires on Suicide

Publisher: name: Stanford Digital Repository
Year: 2023
Subjects: Wildfire, Mental Health, PM2.5, Climate Change.

description: With persistent drought and rising temperatures, wildfires in the United States have become increasingly numerous and destructive. In recent years, researchers have attempted to quantify the impacts of these wildfires across health, industrial, and environmental outcomes. One area of research in this growing body of literature that has been largely overlooked is the effect of wildfires on mental health outcomes. Wildfires and poor mental health outcomes share similar geospatial and seasonal patterns. Fires are also traumatic events to those nearby and indirectly influence many of the factors that affect mental health, including climate, illness and disease. In this paper, we quantify the relationship between wildfires – specifically, proximity to fire events and exposure to smoke – and the most extreme mental health outcome: suicide. We run a fixed effects regression that models county level suicide rate as a function of proximity to the closest wildfire and PM2.5 exposure from fires, incorporating lags to measure effect over time and a vector of meteorological controls that may effect both wildfires and suicide. Despite the trove of anecdotal evidence and speculation connecting wildfires with suicide, we find that proximity to fires and PM2.5 exposure from wildfire exhibit no effect on suicides rates.
