description: Approximately 285 million people in the world are estimated to be visually impaired. In the increasingly complex urban world, indoor and outdoor navigation has become a difficult task for the visually impaired individuals, especially those who use wheelchairs and walking canes. They have limited travel choices and rely mostly on the pedestrian environment. Sidewalks and pedestrian crossings are important for their daily travel. Despite of having the laws that govern proper standards for accessibility-compatible sidewalks, time accessibility of sidewalks gets damaged over a period of time. Due to accessibility issues on sidewalks, travelling independently becomes difficult for the visually impaired wheelchair and walking cane users and they seek support from navigation systems. Real time navigation systems for the visually impaired pedestrians, assist them by notifying about any dangers in their path and navigates them around the obstacles. Machine vision based navigation systems lack a priori contextual information which is necessary for detecting obstacles in real time. Also, use of sensors like RADAR and LIDAR for real time obstacle detection increases the power requirements. Thus, having a priori accessibility maps containing geospatial data of accessibility issue locations is helpful for notifying visually impaired individuals in real time mode. We present WheelNav - a system which uses human-assisted machine vision for developing accurate sidewalk accessibility maps for the navigation of visually impaired individuals. A group of users called Volunteers, crowdsource geotagged images and other relevant information of sidewalk accessibility issues they observe in their city through a smartphone application. Further, computer vision technique called Perspective Transformation is used for identifying the accurate positions of sidewalk accessibility issue objects in crowdsourced images for creating accessibility map. This process is assisted by human workers called Turkers who use Amazon Mechanical Turk and provide feedback about the estimates of real world dimensions of objects in crowdsourced images.

description: The properties of the strongly intensive variable characterizing correlations between the number of particles in two separated rapidity interval in pp interactions at LHC energies are studied in the framework of the string fusion model. We perform the MC simulations of string distributions in the impact parameter plane to take into account the experimental conditions of pp collisions. We account the string fusion processes, leading to the formation of string clusters, embedding a finite lattice (a grid) in the impact parameter plane. As a result, we found the dependence of this variable both on the distance between the centers of the observation windows and their width for the minbias pp collisions at several initial energies. Analyzing these dependencies we can extract the important information on the properties of string clusters. We show that in pp collisions at LHC energies the string fusion effects have a significant impact on the behavior of this strongly intensive variable. The role of these effects is increasing with the initial energy and centrality of collisions. In particular, we found that the increase of this variable with initial energy takes place due to the growth of the portion of the fused string clusters in string configurations arising in pp interactions.

description: Urbanization drives global CO2 levels higher, mainly due to human activities like fossil fuel combustion for heating, industry, and transportation. Emissions vary spatially based on factors like population density, land use or urban structure, underscoring the need to measure and understand local emissions to manage city-wide carbon budgets. The present study analyzes CO2, sensible and latent heat fluxes from two ICOS Associated eddy covariance flux towers in the city of Heraklion, Greece. Despite their proximity, only 1.5 km apart from each other, HECKOR and HECMAS represent distinct land use types: HECKOR is in the commercial city center, while HECMAS is in a residential area. Seasonal and diurnal CO2 flux patterns are therefore significantly different across the sites. HECKOR's fluxes align with commercial and working hours year-round, while HECMAS primarily captures CO2 emissions from residential heating during winter with only small fluxes during other times of the year. Furthermore, there is extreme directionality in CO2 fluxes measured in HECKOR, and thus the estimated diurnal patterns are affected by the seasonality of wind direction patterns. Dynamic flux footprints from both towers are analyzed to link observed CO2 fluxes to specific land use and land cover features. Additionally, we utilize the latest SUEWS CO2 modeling module, integrating TomTom traffic data and flux footprints to assess surface emissions alongside in-situ flux tower data. We also observe higher sensible heat fluxes in HECKOR, most probably due to higher building density and lower vegetation cover in the Heraklion central commercial district.

Repairing partitioned topology

description: In many applications need arises to connect a set of disjoint nodes or segments. Examples include repairing a partitioned network topology after failure, federating a set of standalone networks to serve an emerging event, and connecting a sparsely located data sources. Contemporary solutions either deploy stationary relay nodes  (RN) to form data paths or employ one or multiple mobile data collectors (MDCs) that pick packets from sources and transport them to destinations.  In this thesis we investigate the interconnection problem when the number of available RNs is insufficient for forming a stable topology and a mix of RNs and MDCs is to be used. We present two algorithms for  determining where the RNs are to be placed and planning optimized travel routes for the MDCs so that the data delivery latency as well as the MDC motion overhead are minimized. The performance of the algorithm is validated through simulation.

description: We revisit the sandpile model with ``sticky'' grains introduced by Mohanty and Dhar [Phys. Rev. Lett. {\bf 89}, 104303 (2002)] whose scaling properties were claimed to be in the universality class of directed percolation for both isotropic and directed models. Simulations in the so-called fixed-energy ensemble show that this conclusion is not valid for isotropic sandpiles and that this model shares the same critical properties of other stochastic sandpiles, such as the Manna model. %as expected from the existence of an extra %conservation-law, absent in directed percolation. These results are strengthened by the analysis of the Langevin equations proposed by the same authors to account for this problem which we show to converge, upon coarse-graining, to the well-established set of Langevin equations for the Manna class. Therefore, the presence of a conservation law keeps isotropic sandpiles, with or without stickiness, away from the directed percolation class.

description: Hypertension and traumatic brain injuries have both been shown to have significant impacts on cognition and both have proposed mechanisms related to cerebral perfusion and asymptomatic brain pathology, but no research has linked hypertension and traumatic brain injury on neuropsychological functioning. I hypothesized that hypertension status  and mild traumatic brain injury history would interact to predict worse cognitive functioning than hypertension or mild traumatic brain injury history alone. A sample of 156 participants was used from a parent study looking at cardiovascular disease and the brain. Multiple regression analyses were implemented to investigate whether the interaction of hypertension status and mild traumatic brain injury history significantly predicted neuropsychological test results controlling for age, sex, race, education, hypertensive medication use, smoking status, alcohol use per week, and depressive symptomatology. Results showed that no significant interactions existed between hypertension and mild traumatic brain injury, but simple effects of hypertension status predicted Trail Making Test B time and Grooved Pegboard Dominant Hand time. It is possible that mild traumatic brain injury status does not interact with hypertension status, or that methodological issues with the study interfered with significant relations. Future studies should investigate if more severe head injuries or if the full range of blood pressure impacts cognitive functioning.

description: The n-alkanes C12H26, C14H30, and C16H34 have been imbibed and solidified in mesoporous Vycor glass with a mean pore diameter of 10nm. The samples have been investigated by x-ray diffractometry and calorimetric measurements. The structures and phase sequences have been determined. Apart from a reduction and the hysteresis of the melting/freezing transition, pore confined C12 reproduces the liquid-triclinic phase sequence of the bulk material, but for C16 an orthorhombic rotator mesophase appears that in the bulk state is absent for C16 but well known from odd numbered alkanes of similar length. In pore confined C14 this phase shows up on cooling but not on heating.

description: Recent works have shown the important role Nonlinear Electrodynamics (NLED) can have in two crucial questions of Cosmology, concerning particular moments of its evolution for very large and for low-curvature regimes, that is for very condensed phase and at the present period of acceleration. We present here a toy model of a complete cosmological scenario in which the main factor responsible for the geometry is a nonlinear magnetic field which produces a FRW homogeneous and isotropic geometry. In this scenario we distinguish four distinct phases: a bouncing period, a radiation era, an acceleration era and a re-bouncing. It has already been shown that in NLED a strong magnetic field can overcome the inevitability of a singular region typical of linear Maxwell theory; on the other extreme situation, that is for very weak magnetic field it can accelerate the expansion. The present model goes one step further: after the acceleration phase the universe re-bounces and enter in a collapse era. This behavior is a manifestation of the invariance under the dual map of the scale factor $ a(t) \to 1/ a(t),$ a consequence of the corresponding inverse symmetry of the electromagnetic field ($ F \to 1/ F,$ where $F \equiv F^{μν}F_{μν}$) of the NLED theory presented here. Such sequence collapse-bouncing-expansion-acceleration-re-bouncing-collapse constitutes a basic unitary element for the structure of the universe that can be repeated indefinitely yielding what we call a Cyclic Magnetic Universe.

description: We investigate the transition of the polarized photon structure function $g_1^γ(x,Q^2,P^2)$ when the target photon shifts from on-shell ($P^2=0$) to far off-shell ($P^2\gg Λ^2$) region. The analysis is performed to the next-to-leading order in QCD. The first moment of $g_1^γ$ which vanishes for the real photon, turns to be a negative value when target photon becomes off-shell. The explicit $P^2$-dependence of the first moment sum rule as well as of the structure function $g_1^γ(x,Q^2,P^2)$ as a function of $x$ is studied in the framework of the vector meson dominance model.

description: Conventionally, classical scholarship has ascribed the inception of philosophy and culture to the Greeks, whilst relegating military strategy and imperialism to the Romans. This tradition dates back to Vergil's famous comment in Book 6 of the Aeneid, that others (Greeks) will create beautiful statuary, plead eloquently in the law courts and chart the skies and constellations; whereas the Romans' job will be to rule over others with their imperium. This tendency to oversimplify the differences between Greeks and Romans appears to be changing; however, the changes are tinged with a distinct Grecocentric bias. Roman culture, to date, is not being scrutinised with the same perspicacity, as that of the Greeks, and current research that challenges the traditional prejudices of conventional opinions are effectively absent. This thesis examines the unique aspects of Roman culture and identity and demonstrates that they too developed a highly defined world-view that was richly distinct from Greek conceptions of their oikumene. This distinction is perhaps most obvious in Roman stereotypes of the 'other'. Complex and thoroughly Roman, it was based on principals of cosmological determinism and guided by a potent form of exceptionalism and manifest destiny. Romans harnessed theo-philosophical arguments, to design a world in which their hegemony was efficiently rationalised by the elite and justified by the gods themselves. As part of this examination, the cultural precursors, Italic and otherwise, are scrutinised, as are indigenous ethnic markers of Roman identity, so as to better ascertain distinctly Roman and borrowed beliefs that came to characterise the Late Republican and Early Imperial Roman habitus. Furthermore, Roman religious beliefs are also examined where they relate to Roman views of the cosmos and their place within the relational meta-narrative of divinely mandated human history. Within this scope, Roman notions of cosmological determinism and details regarding their specific role in the formation of unique ethnic stereotypes is analysed. Moreover, the impact of these stereotypes on Roman attitudes and policies - particularly foreign policy - will be discussed in detail. This detail will extend to include the previously mentioned notions of Roman exceptionalism and manifest destiny and will be done so in a comparative context by utilising the political discourse and definitions related to the heuristic models of American exceptionalism and manifest destiny.

description: A series of new macrocycles based on alkyl glycosides derived from D-glucose and D-galactose was synthesized. The macrocycles were easily obtained by the reaction of dialkynyl derivatives with diazides via copper-catlyzed 1,3-cycloaddition reaction. Simple protecting group strategies were applied to obtain the vicinal dihydroxy derivatives, followed by Williamson etherification with propargyl bromides to get the dialkynyl derivatives. These derivatives were subjected to 1,3-Hüisgen triazole coupling with diazides furnishing the macrocycles in good yields. The 1,3-Hüisgen reaction used to build these macrocycles was investigated thoroughly with respect to reaction time, catalysts, solvents, and temperature for optimum macrocyclisation.

description: We consider rational nonlinear electrodynamics with the Lagrangian ${\cal L} = -{\cal F}/(1+2β{\cal F})$ (${\cal F}=(1/4)F_{μν}F^{μν}$ is the Lorentz-invariant), proposed in [63], coupled to General Relativity. The effective geometry induced by nonlinear electrodynamics corrections are found. We determine shadow's size of regular non-rotating magnetic black holes and compare them with the shadow size of the super-massive M87* black hole imaged by the Event Horizon Telescope collaboration. Assuming that the black hole mass has a pure electromagnetic nature, we obtain the black hole magnetic charge. The size of the shadow obtained is very close to the shadow size of non-regular neutral Schwarzschild black holes. As a result, we can interpret the super-massive M87* black hole as a regular (without singularities) magnetized black hole.

description: In attempt to address the adult obesity epidemic in the U.S., several state legislatures have enacted laws to curtail rates of adult obesity (Stein & Colditz, 2004).  Recent enacted policies include: menu labeling laws, snack taxes, and Complete Streets policy (Robert Wood Johnson, 2009). The aim of this dissertation was to evaluate the effectiveness of existing legislative efforts to limit rates of growth of adult obesity.  I examined if anti-obesity legislation effectively reduces rates of adult obesity and if anti-obesity policies differ in their ability to diminish adult obesity. Several panel data sets were constructed using reported data for each state and the District of Columbia from 1995 to 2011 via the Behavioral Risk Factor Surveillance System (BRFSS), U.S. Department of Commerce, Bureau of Economic Analysis and the U.S. Census Bureau. Time series regression analysis was completed to assess the impact of these three policies at a state, group and individual level. At the state level, all three policies are associated with a decrease in adult obesity rates although, the magnitude is small and statistical significance varies by empirical model.  At the individual level, all three policies are associated with a decrease in BMI, however, the magnitude is small and the only policy with statistical significance is menu labeling. At the group level, the policies vary in their effect on BMI by race, age, income, education and gender. Only menu labeling and snack tax policy are statistically significant at the group level. Although the magnitude of effect seen with these policies is small, any sign of a reversal in the growing obesity trend, a trend that has been unaltered for the past decade, could be seen as a sign of improvement from a public health perspective.  The results of this study highlight how a one size fits all approach will not be effective in combating the obesity epidemic, rather an assortment of legislative policies are necessary.

description: We identify important issues in the application of digital forensics to Infrastructure-as-a-Service cloud computing and develop new practical forensic tools and techniques to facilitate forensic exams of the cloud. When investigating suspected cases involving cloud computing, forensic examiners have been poorly equipped to deal with the technical and legal challenges. Because data in the cloud are remote, distributed, and elastic, these challenges include understanding the cloud environment, acquiring and analyzing data remotely, and applying the law to a new domain. Today digital forensics for cloud computing is challenging at best, but can be performed in a manner consistent with federal law using the tools and techniques we developed. The first problem is understanding how and why criminal and civil actions in and against cloud computing are unique and difficult to prosecute. We analyze a digital forensic investigation of crime in the cloud, and present two hypothetical case studies that illustrate the unique challenges of acquisition, chain of custody, trust, and forensic integrity. Understanding these issues introduces legal challenges which are also important for federal, state, and local law enforcement who will soon be called upon to conduct cloud investigations. The second problem is the lack of practical technical tools to conduct cloud forensics. We examine the capabilities for forensics today, evaluate the use of existing tools including EnCase and FTK, and discuss why these tools are incapable of trustworthy cloud acquisition. We design consumer-driven forensic capabilities for OpenStack, including new features for acquiring trustworthy firewall logs, API logs, and disk images. The third problem is a deficit of legal instruments for seizing cloud-based electronically-stored information. We analyze the application of existing policies and laws to the new domain of cloud computing by analyzing case law and legal opinions about digital evidence discovery, and suggest modifications that would enhance cloud the prosecution of cloud- based crimes. We offer guidance about how to author a search warrant for cloud data, and what pertinent data to request. This dissertation enhances our understanding of technical, trust, and legal issues needed to investigate cloud-based crimes and offers new tools and techniques to facilitate such investigations.

description: Protoplanets develop via collisions between planetesimals and planetary embryos in the final assembly stage of planet formation. The efficiency of the planet formation can be defined by the mass ratio between formed protoplanets and the initial mass of embryos and planetesimals. In final assembly planet formation models, the gravitational interactions between planetesimals are usually neglected due to computational difficulties, namely, computations require fewer resources in this way. We investigated the effect of this simplification via modeling the planet formation efficiency in a circumstellar belt of embryos and self-interacting or non-self-interacting planetesimals. We used our own developed GPU-based direct N-body integrator, HIPERION, for the simulations. We found that planet formation efficiency is higher if the planetesimal self-interaction is taken into account in models that contain the commonly used 100 embryos. The observed effect can be explained by the damping of planetesimal eccentricities by their self-gravity. The non-self-interacting and self-interacting models show qualitatively the same results if the initial number of embryos is above 200.

description: Underage alcohol consumption is a problem in the United States where nearly one-third of youth report first consuming alcohol before the age of 13.  Currently, this amounts to at least 9.3 million underage drinkers.   Although originally implemented to reduce youth crime (with mixed effectiveness) and not as a means of deterring underage drinking, juvenile curfew laws have had an effect on adolescents' behavior.  These laws seek to provide general protection to youth and adults by restricting the times that children of certain ages are allowed to occupy public places or streets. These laws often contain exemptions, such as allowing youths to be accompanied by adults, to respond to an emergency, or to travel to or from school, work, or a religious service.  This dissertation: (a) investigates the history of curfew laws in the United States and reviews the studies that have been done to date [Article 1]; (b) provides a legal analysis of cases involving curfew laws and offers guidance for how curfew laws can be drafted to avoid being overturned in a legal challenge [Article 2]; and, (c) examines whether curfew laws are effective at reducing underage alcohol consumption [Article 3].

description: The growing use of cyber-services automatically impart great importance to cybersecurity. The Internet is a primary source of information regarding software flaws, vulnerabilities, cyber-attacks and exploits. This information is available through vulnerability databases, news articles, security bulletins and blogs. Variety of applications and security systems like Intrusion Detection Systems (IDS), Intrusion Prevention System (IPS), etc. can take advantage of this information for consolidating their infrastructure. The lack of availability of ready text corpus of high quality security information from various sources makes it difficult for these applications to use this information. To overcome this problem our work focuses on building a multi-genre corpus of security text using information retrieved from multiple internet based sources; National Vulnerabilities Database, Wikipedia articles, security blogs, security bulletins and scholarly papers. The system builds a text classifier from the initial high quality data which is used to classify and accommodate new data from these sources into the corpus. This corpus can be used by variety of applications like IDS or IPS, in variety of ways like assertion into knowledge base or extraction of named entities. Our work explores one of the applications of generating the semantic text similarity model for cybersecurity text. We use the multi-genre cybersecurity text corpus for creating the word co-occurrence model. This model can extract the synonymity between the different security terms. For example, the words 'virus' and 'malware' that have same context are scored for their degree of similarity. The word co-occurrence model is then extended to generate a semantic text similarity model.The text similarity model extracts the semantic text similarity between different security texts like titles of the papers, vulnerability descriptions, blog paragraphs, etc. The system also develops a combined text similarity  model from cybersecurity similarity model and generic text similarity model. This model can be used in document mining for matching security text, clustering documents describing similar vulnerabilities and so on.

description: Most prior art in visual understanding relies solely on analyzing the "what" (e.g., event recognition) and "where" (e.g., event localization), which in some cases, fails to describe correct contextual relationships between events or leads to incorrect underlying visual attention. Part of what defines us as human and fundamentally different from machines is our instinct to seek causality behind any association, say an event Y that happened as a direct result of event X. To this end, we propose iPerceive, a framework capable of understanding the "why" between events in a video by building a common-sense knowledge base using contextual cues to infer causal relationships between objects in the video. We demonstrate the effectiveness of our technique using the dense video captioning (DVC) and video question answering (VideoQA) tasks. Furthermore, while most prior work in DVC and VideoQA relies solely on visual information, other modalities such as audio and speech are vital for a human observer's perception of an environment. We formulate DVC and VideoQA tasks as machine translation problems that utilize multiple modalities. By evaluating the performance of iPerceive DVC and iPerceive VideoQA on the ActivityNet Captions and TVQA datasets respectively, we show that our approach furthers the state-of-the-art.

description: The various sources of Rational Terms contributing to the one-loop amplitudes are critically discussed. We show that the terms originating from the generic (n-4)-dimensional structure of the numerator of the one-loop amplitude can be derived by using appropriate Feynman rules within a tree-like computation. For the terms that originate from the reduction of the 4-dimensional part of the numerator, we present two different strategies and explicit algorithms to compute them.

description: Optical control of electronic spins is the basis for ultrafast spintronics: circularly polarized light in combination with spin-orbit coupling of the electronic states allows for spin manipulation in condensed matter. However, the conventional approach is limited to spin orientation along one particular orientation that is dictated by the direction of photon propagation. Plasmonics opens new capabilities, allowing one to tailor the light polarization at the nanoscale. Here, we demonstrate ultrafast optical excitation of electron spin on femtosecond time scales via plasmon to exciton spin conversion. By time-resolving the THz spin dynamics in a hybrid (Cd,Mn)Te quantum well structure covered with a metallic grating, we unambiguously determine the orientation of the photoexcited electron spins which is locked to the propagation direction of surface plasmon-polaritons. Using the spin of the incident photons as additional degree of freedom, one can orient the photoexcited electron spin at will in a two-dimensional plane.

description: We investigate temperature dependent electronic correlation effects in the conduction bands of Gadolinium Nitride (GdN) based on the combination of many body analysis of the multi-band Kondo lattice model and the first principles TB-LMTO bandstructure calculations. The physical properties like the quasi-particle density of states (Q-DOS), spectral density (SD) and quasi-particle bandstructure (Q-BS) are calculated and discussed. The results can be compared with spin and angle resolved inverse photoemission spectroscopy (ARIPS) of the conduction bands of GdN. A redshift of 0.34 eV of the lower band edge (T=$T_{c}$ $\to$ T=0) is obtained and found in close comparison with earlier theoretical prediction and experimental value reported in the literature.

Youth adjustment in the context of neighborhood disadvantage: A focus on stress, coping, and mental health
Creators: name: Westin, Anna
Publisher: name: Maryland Shared Open Access Repository
Year: 2014

description: Growing up in urban neighborhood disadvantage, an environment characterized by severe and pervasive stress exposure, is associated with negative outcomes for youth. African American children are disproportionately exposed to neighborhood disadvantage; yet, little research has been conducted among this population. This two-part study uses quantitative and qualitative approaches to better understand the experience of growing up in neighborhood disadvantage. The quantitative component examined the fit of a model predicting adjustment (risky behaviors; internalizing and externalizing mental health) from disadvantage (family, housing, and neighborhood systems), including the influence of age and sex. Participants included 519 African American youth, ages 12-19, from five major cities in the US, who were members of the control group of a larger study.  The qualitative component explored youths' perspective on stress, coping, and mental health with particular attention to different invariant meaning structures emerging by sex, age, and neighborhood. One hundred African American youth, ages 15-23, all residents of Baltimore, were interviewed as part of a larger study. Findings from this two-part study complement each other, suggesting that African American youth growing up in disadvantaged neighborhoods are exposed to severe and chronic stress across multiple systems. The quantitative component showed that this risk exposure was associated with negative youth adjustment through direct and indirect effects. The qualitative component identified unique stressors, coping strategies, and experiences with mental health. The complexity of risk and adjustment, and their interrelatedness in the challenging environment of neighborhood disadvantage, were apparent in both components of the study. Implications for families, mental health providers, and policy makers are discussed.
Factors influencing the formation of organic-rich sedimentary facies: Examples from the Devonian-carboniferous Exshaw formation, Alberta, Canada
Creators: name: Caplan, Mark Laurence
Publisher: name: University of British Columbia

description: A unique set of palaeo-oceanographic conditions is responsible for formation of Devonian-Carboniferous organic-rich, laminated mudrocks. These conditions are poorly understood as widespread development of mudrocks is not witnessed in modern oceans. Multidisciplinary research of the organic-rich Famennian-Tournaisian Exshaw mudrocks (lithofacies B₁) and subjacent Famennian Big Valley carbonate ramp deposits of the Alberta Unstable Cratonic Platform (AUCP) indicate that eutrophication of surface waters led to carbonate ramp demise and deposition of Exshaw mudrocks. The onset of eutrophication coincided with a relative sea level rise as Exshaw and Big Valley deposits onlap paleobathymetric highs developed on the AUCP. An abrupt relative sea-level fall at the D-C boundary is evidenced by progradation of nearshore marine shoreline cross-bedded sandstones, bioturbated siltstones and organic-lean mudrocks (lithofacies B₂) over distal epicontinental shelf organic-rich mudrocks. A second transgressive event is reflected by retrogradation of the shoreface in southeastern Alberta, culminating in deposition of organic-rich, laminated mudrocks of the Banff Formation. Sedimentology, ichnology, palaeontology and geochemistry (XRF, XRD, Ϩ¹⁵Ntot and Ϩ¹³Corg isotopes, FTIR and ROCK-EVAL) have been utilized to examine the genesis of organic-rich (lithofacies B₁and organic-lean (lithofacies B₂) laminated Exshaw mudrocks. Lithofacies B₁ displays high TOC's, lighter Ϩ¹⁵Ntot high HI and lower Ox.I. (ratio of oxygen functional groups to aliphatic organic compounds) indicating high primary production and supply of labile organic matter to the sea floor. Lithofacies B₂ which sharply overlies lithofacies B₁ in the distal shelf region of north-central Alberta, displays low TOC's, heavier Ϩ¹⁵Ntot low HI and higher Ox.I. indicating low primary production and a decreased supply of more refractory organic matter to the sea floor. Both primary productivity and degree of organic matter recycling in the water column were important in governing organic matter quality and quantity. Global distribution of laminated D-C mudrocks are equated with the Hangenberg mass extinction event. The development of black mudrocks and anoxic benthic conditions were restricted to low palaeolatitudes resulting in demise of carbonate platforms. Global cooling and resultant glaciation in Gondwana enhanced oceanic circulation, upwelling efficiency, generation and burial of carbon in marine sediments. These effects led to the development of anoxic benthic environments, mass extinction and production of globally distributed organic-rich mudrocks.
Comment on: "Harmonic oscillator in an environment with a pointlike defect". Phys. Scr. \textbf{94} ( 2019) 125301

description: We analyze recent results for a harmonic oscillator in an environment with a pointlike defect. We show that the allowed oscillator frequencies predicted by the authors stem from a misinterpretation of the exact solutions of a conditionally solvable eigenvalue equation. Also the exact eigenvalues derived by those authors are meaningless because they belong to different quantum-mechanical models.
