description: We report on a facile procedure for synthesis of nanoporous coatings of tungstic silica through wet-chemical deposition and post-treatment of tungsten-doped potassium silicate solutions. The process relies on an aqueous washing and ion exchange step where dispersed potassium salt deposits are removed from a 150 nm silicate gel layer. Through an adjustment of the pH value of the washing agent within the solubility regime of a tungstic salt precursor, the tungsten content of the remaining nanostructured coating can be controlled. We propose this route as a universal approach for the deposition of large-area coatings of nanoporous silica with the potential for incorporating a broad variety of other dopant species. As for the present case, we observe, on the one hand, antireflective properties which enable the reduction of reflection losses from float glass by up to 3.7 percent points. On the other hand, the incorporation of nanoscale tungstic precipitates provides a lever for tailoring the coating hydrophilicity and, eventually, also surface acidity. This may provide a future route for combining optical performance with anti-fouling functionality.

description: Geotechnical anchoring technology is an important tool for disaster prevention and mitigation in slope engineering. Anchor bolts which are commonly used in slope engineering can be divided into prestressed anchors and non-prestressed anchors. Due to the superiority of anchor support technology, research on various aspects of anchor bolts, such as mechanical mechanism, anchorage effect, and the development of new-type anchor bolts, has been a significant research topic for scholars. This mini-review sums up the diverse past and current literature on anchor support technology of slope engineering in China. It focuses on the characteristics, applications, research methods, and practical cases of anchor bolts and briefly describes the history of slope anchor bolt development in China in the past 3 decades. Nowadays, the demand for engineering construction processes is increasing, and engineering geological conditions are becoming more complex, which promotes the development of anchor support technology. At the international level, achieving carbon neutrality is both an international trend and a general objective. Against the background of global commitment to carbon neutrality, the potential future perspectives for the developments of anchor support technology have been prospected in light of actual engineering needs.

description: With the advent of new loads and photovoltaic panels, voltage fluctuation has increased, especially in active distribution networks with a high penetration of distributed resources and a large deployment of electric vehicles. All this leads to greater uncertainty in future consumption patterns, which gives greater importance to predictive models capable of adapting in real time to unexpected variations. Given the current metering and communication infrastructure of smart meters in Spain, it is not feasible to request real-time data from all consumers. However, it is possible to communicate online with a few, which we call guard (or sentinel) smart meters. The results present (I) a novel methodology to select the sentinel meters and (II) their integration in predictive models based on neural networks, improving their ability to adapt and anticipate future states. For the analyses we have used (i) data from three groups of meters belonging to the living lab of a DSO, (ii) data from the head-end feeders of the transformer substation and (iii) data from the nearest weather station.

description: Let X1,…,Xn be an i.i.d. sample in Rp with zero mean and the covariance matrix Σ∗. The classical PCA approach recovers the projector P∗J onto the principal eigenspace of Σ∗ by its empirical counterpart ˆPJ. Recent paper [24] investigated the asymptotic distribution of the Frobenius distance between the projectors ∥ˆPJ−P∗J∥2, while [27] offered a bootstrap procedure to measure uncertainty in recovering this subspace P∗J even in a finite sample setup. The present paper considers this problem from a Bayesian perspective and suggests to use the credible sets of the pseudo-posterior distribution on the space of covariance matrices induced by the conjugated Inverse Wishart prior as sharp confidence sets. This yields a numerically efficient procedure. Moreover, we theoretically justify this method and derive finite sample bounds on the corresponding coverage probability. Contrary to [24, 27], the obtained results are valid for non-Gaussian data: the main assumption that we impose is the concentration of the sample covariance ˆΣ in a vicinity of Σ∗. Numerical simulations illustrate good performance of the proposed procedure even on non-Gaussian data in a rather challenging regime.

The pan-Arctic domain is undergoing some of Earth's most rapid and significant changes resulting from anthropogenic and climate-induced alteration of freshwater distribution. Changes in terrestrial freshwater discharge entering the Arctic Basin from pan-Arctic watersheds significantly impact oceanic circulation and sea ice dynamics. Historical streamflow records in high-latitude basins are often discontinuous (seasonal or with large temporal gaps) or sparse (poor spatial coverage), however, making trends from observed records difficult to quantify. Our objectives were to generate a more continuous 90-year record (1981-2070) of spatially distributed freshwater flux for the Arctic Basin (all Arctic draining rivers, including the Yukon), suitable for forcing ocean models, and to analyze the changing simulated trends in freshwater discharge across the domain. We established these data as valid during the historical period (1971-2015) and then used projected futures (preserving uncertainty by running a coupled climate-hydrologic ensemble) to analyze long-term (2021-2070) trends for major Arctic draining rivers. When compared to historic trends reported in the literature, we find that trends are projected to nearly double by 2070, with river discharge to the Arctic Basin increasing by 22% (on average) by 2070. We also find a significant trend toward earlier onset of spring freshet and a general flattening of the average annual hydrograph, with a trend toward decreasing seasonality of Arctic freshwater discharge with climate change and regulation combined. The coupled climate-hydrologic ensemble was then used to force an ocean circulation model to simulate freshwater content and thermohaline circulation. This research provides the marine research community with a daily time series of historic and projected freshwater discharge suitable for forcing sea ice and ocean models. Although important, this work is only a first step in mapping the impacts of climate change on the pan-Arctic region.

description: Layered Na0.8Co0.8Ti0.2O2 oxide crystallizes in the β-RbScO2 structure type (P2 modification) with Co(III) and Ti(IV) cations sharing the same crystallographic site in the metal-oxygen layers. It was synthesized as a single-phase material and characterized as a cathode in Na- and Na-ion batteries. A reversible capacity of about 110 mA h g−1 was obtained during cycling between 4.2 and 1.8 V vs. Na+/Na with a 0.1 C current density. This potential window corresponds to minor structural changes during (de)sodiation, evaluated from operando XRD analysis. This finding is in contrast to Ti-free NaxCoO2 materials showing a multi-step reaction mechanism, thus identifying Ti as a structure stabilizer, similar to other layered O3- and P2-NaxCo1−yTiyO2 oxides. However, charging the battery with the Na0.8Co0.8Ti0.2O2 cathode above 4.2 V results in the reversible formation of a O2-phase, while discharging below 1.5 V leads to the appearance of a second P2-layered phase with a larger unit cell, which disappears completely during subsequent battery charge. Extension of the potential window to higher or lower potentials beyond the 4.2–1.8 V range leads to a faster deterioration of the electrochemical performance. After 100 charging-discharging cycles between 4.2 and 1.8 V, the battery showed a capacity loss of about 20% in a conventional carbonate-based electrolyte. In order to improve the cycling stability, different approaches including protective coatings or layers of the cathodic and anodic surface were applied and compared with each other.

description: Complex systems can, to a first approximation, be characterized by the fact that their dynamics emerging at the macroscopic level cannot be easily explained from the microscopic dynamics of the individual constituents of the system. This property of complex systems can be identified in virtually all natural systems surrounding us, but also in many social, economic, and technological systems. The defining characteristics of complex systems imply that their dynamics can often only be captured from the analysis of simulated or observed data. Here, we summarize recent advances in nonlinear data analysis of both simulated and real-world complex systems, with a focus on recurrence analysis for the investigation of individual or small sets of time series, and complex networks for the analysis of possibly very large, spatiotemporal datasets. We review and explain the recent success of these two key concepts of complexity science with an emphasis on applications for the analysis of geoscientific and in particular (palaeo-) climate data. In particular, we present several prominent examples where challenging problems in Earth system and climate science have been successfully addressed using recurrence analysis and complex networks. We outline several open questions for future lines of research in the direction of data-based complex system analysis, again with a focus on applications in the Earth sciences, and suggest possible combinations with suitable machine learning approaches. Beyond Earth system analysis, these methods have proven valuable also in many other scientific disciplines, such as neuroscience, physiology, epidemics, or engineering.

Understanding the Impact Presidential Rhetoric Has on Coalition Building
Creators: name: Gilliard, Jordyn
Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: Rhetoric

description: Literature suggests that coalition building depends on legitimacy, political incentives, proximity and shared culture. However, I find that presidential rhetoric appears to be one of the most influential conditions when seeking to form a coalition in the absence of legitimacy, incentives, proximity and shared culture. Establishing a coalition requires collaboration between a diverse set of sovereign state actors, and highlighting shared interests. To cultivate collaboration the president must appeal to his audience through the use of rhetoric. Thus the U.S president can strengthen their shared interest argument by incorporating principles of moral foundations theory into their argument to enhance the appeal. The theory revolves around a set of five universally accepted values that explain moral reasoning and discusses why humans arrive at the conclusions they do. Moral foundations theory can help explain the underlying causes for states’ willingness to join military coalitions with the United States. However, as revealed within the study different audiences attract to different moral intuitions. The overall findings suggests that by incorporating moral intuitions into presidential speeches to emphasize shared interests, the president is able to further persuade state actors to form a coalition. Though the president’s usage of the moral foundations theory may not be intentional, the theory can help us advance literature on how coalition building is established. With a large coalition the president can advance policy objectives such as liberty, freedom and other democratic norms. Hence, the goal of this research paper is to present cases that display presidential rhetoric in use as the president uses values of moral intuition to help strengthen their argument that nations should collaborate with the United States because of shared interests.

description: The covalent attachment of molecular photosensitizers (PS) to polyoxometalates (POMs) opens new pathways to PS-POM dyads for light-driven charge-transfer and charge-storage. Here, we report a synthetic route for the covalent linkage of BODIPY-dyes to Anderson-type polyoxomolybdates by using CLICK chemistry (i. e. copper-catalyzed azide-alkyne cycloaddition, CuAAC). Photophysical properties of the dyad were investigated by combined experimental and theoretical methods and highlight the role of both sub-components for the charge-separation properties. The study demonstrates how CLICK chemistry can be used for the versatile linkage of organic functional units to molecular metal oxide clusters. © 2021 The Authors.

description: This body of work involves the preparation, structural characterization, and application-driven evaluation of biomaterials comprised of nanocarbon (graphene-derived) and synthetic polypeptide building blocks. The overarching goal of this work is to create graphenic and polypeptide-based biomaterials that are specifically designed to interact with the biological environment through chemical and physical pathways in order to provoke a therapeutic response – for example, to support a natural healing process, to direct the repair of a damaged tissue, or to treat a chemical imbalance in the body. Part 1 of this thesis explores the synthesis of functional graphenic materials (FGMs) with tunable surface chemistry and evaluates their use as scaffolds for mammalian cell regeneration (Chapter 2), bacterio-adhesive or repulsive surfaces (Chapter 3), and antibiofilm coatings (Chapter 3). Part 2 of this thesis contains work regarding the synthesis of polypeptides with sequence-driven, biologically relevant functionality by the ring-opening polymerization of -amino acid N-carboxyanhydride (NCA) and N-thiocarboxyanhydride (NTA) monomers. In doing so, Part 2 addresses two areas of interest within the field of biomaterial science: 1) investigation of new biomedical applications of polypeptides (Chapter 6), and 2) development of new synthetic routes to access functional polypeptides with architectural control (Chapters 7 and 8). The work described in this thesis is framed in the context of how these macromolecular systems can be leveraged to interact with the biological environment and serve a therapeutic function.
Private Military Organizations, Resource Concessions, and Conflict Termination: How Private Military Organizations Impact Conflict Duration in African Civil Wars

description: This paper attempts to address the lingering question about the impact that private military organizations have in conflicts they engage in. This paper focuses on civil conflicts in Africa which have had private military presence and limits the time frame to the years between 1990 and 2008. Specifically, I seek to analyze the relationship between resource concessions made to a private military organization and the likelihood of conflict termination. I utilize both case study analysis and survival analysis to address the research question. In the survival model, I find a trend that indicates that a conflict in which the private military organization is awarded a resource concession is less likely to terminate at a given year y, but was unable to reject the null hypothesis due to insignificant models. The case study analysis demonstrates that private military organizations that have been awarded resource concessions are more likely to impact the conflict on multiple levels, being politically and militarily.
Dynamic Cerebral Autoregulation, Neurovascular Coupling and Cerebral Haemodynamic Parameters: Clinical Applications

Year: 2022
Subjects: Uncategorized

description: Background: Dynamic cerebral autoregulation (dCA) and neurovascular coupling (NVC) are the main mechanisms that regulate cerebral blood flow. There is a need to improve methods of assessment and also to study their interaction. Objectives: This thesis aimed to advance methods for assessing autoregulatory and neuro-vascular processes and study the interaction of these regulatory mechanisms in health and disease. For this purpose, both time- and frequency-domain methods were explored aiming to improve their sensitivity to detect changes in cognitive load and autoregulatory performance. Methods: Data comprised retrospective and prospective studies involving non-invasive measurements of cerebral blood flow velocity, blood pressure and end-tidal carbon dioxide in healthy subjects and patients with mild-to-moderate ischaemic stroke, mid cognitive impairment, and Alzheimer’s disease. Results: i) in 16 healthy subjects (8 males, age 31.6±11.6 years), similar CBFV temporal patterns were seen with varying complexity and duration of cognitive paradigms, but a trend for critical closing pressure to alter in respect of task complexity; ii) a shorter 3-minute duration recording analysis can detect cerebral-autoregulatory impairment in 79 ischaemic strokes (55 males, age 67.5±12.2 years), compared with 78 healthy controls (41 males, age 52.0±16.3 years); iii) cerebral autoregulation was depressed by neural stimulation with fluency and attention domain tasks in younger adults and memory and language tasks in older adults, but not additionally affected in 22 patients with mild cognitive impairment (18 males, age 72.3±8.5 years) and 35 with Alzheimer’s disease (23 males, age 72.2±8.9 years) compared to 30 healthy older adults (17 males, age 67.0±8.6 years). Conclusion: Modifying common cognitive paradigms with varying complexity and duration could not provide scalability in neurovascular coupling responses, but analysis of subcomponents potentially reflects metabolic demand. Many future avenues of research follow from this work, including different study populations, types of cognitive paradigms and modelling approaches.

Investigating Photophysical and Photochemical Structure-Activity Relationships of Heteroleptic Ir(III) Transition Metal Complexes Using High-throughput and Automated Techniques

description: Photocatalysis centers on the transformation of photon energy to chemical energy. These reactions are frequently driven by a photocatalyst, which is solely responsible for absorbing a particular wavelength of light and transferring that energy to selected substrates. The capacity of a photocatalyst to transform a molar amount of photons (1 mole of photons = 1 einstein) to a molar amount of photoproduct is governed by the molecular structure of the photocatalyst, which in the case of transition metal photocatalysts is strongly dependent on ligand molecular structure. It is therefore of theoretical interest to quantitatively elucidate correlations between features of ligand molecular structure and the resultant photocatalyst activity. Herein, high-throughput synthetic and experimental procedures as well as automated data analysis algorithms are invoked to investigate structure-function trends among heteroleptic [Ir(C^N)2(N^N)]+ transition metal complexes (where C^N represents an ortho-metalated cyclometalating ligand and N^N is a diimine ancillary ligand). Datasets pertaining to the photophysical properties and photochemical activity of 1,440 screened Ir(III) complexes (generated from 60 C^N ligands and 24 N^N ligands) were obtained through measurement of the UV-visible absorption spectra, deaerated excited state lifetime and emission spectra, and online kinetic data collection for the photodeposition of Sn(0) and Zn(0) from their respective cationic salts in solution. Automated analysis of this raw data, as well as the derivation of a photokinetic rate law, elucidated the sought-after ligand-based structure-function trends. This was achievable through the use of high-throughput experimental techniques capable of measuring features pertinent to each step in a photochemical cycle (i.e., absorption, intersystem crossing/internal conversion, and all associated electron transfer events). The findings from this unprecedentedly large dataset provided judicious guidelines to uncover ligands capable of making heteroleptic Rh(III) complexes of the same ligand stoichiometry possessing the photophysical and photochemical properties required for successful photocatalytic activity in water reduction systems, representing the first report of mononuclear Rh(III) photocatalytic activity. Finally, the ligand based photophysical trends provided engineering requirements needed to synthesize a novel heteroleptic Ir(III) guest in light-emitting electrochemical cells (LEECs) coupled to a perovskite host. These materials exhibited the highest reported efficiencies in the literature for this class of light emitting devices.

description: Paropsisterna Motschulsky, 1860
Type species: Notoclea sexpustulata Marsham, 1808, by original designation.
A key identifying the genus Paropsisterna in Australia, generic description and full generic synonymy are provided by Reid (2006). The new species is a typical member of Paropsisterna. From other European genera of Chrysomelinae (Mohr, 1966; Bienkowski, 2004; Borowiec, 2011), the adult of Paropsisterna is easily distinguished by: colour loss after death; apical maxillary palpomere strongly expanded to apex; trichobothria absent from pronotal angles; pronotum with complete marginal beading; procoxal cavities wide open; elytral epipleura hidden in lateral view (internally reflexed) and without setae; anterior of mesoventrite deeply hollowed to accommodate apex of prosternal process; apices of tibiae not abruptly expanded; mid and hind tibiae excavate on outer apical third; third tarsomere not deeply bilobed; claws acutely toothed; abdominal ventrites not fused. The larva is distinguished from other western European genera (Cox 1982; Steinhausen 2001) by: single pair of dorsal glands between abdominal segments 7 and 8, transverse dorsal tubercles absent from posthoracic and anterior abdominal segments, body elongate, antennae inserted on prominent flanges.

description: Conjugated organic materials have become industry standards for handheld devices due to their advantageous properties leading to thinner and ecofriendly optoelectronics. However, both small molecules and polymers are limited by their susceptibility to aggregation at concentrations required for device fabrication. Aggregation can lead to enhanced charge transport but will then quench the emission of the conjugated molecules. Therefore, it is important to be able to control the degree and type of intermolecular packing that occurs in these materials. Poly(3-hexylthiophene) (P3HT) is a well-studied benchmark system for semiconducting polymers used in optoelectronic devices. Within this work, we use P3HT to develop methods to more accurately characterize the heterogeneity of this polymer in various environments achieved through solvent poisoning techniques. We first explored the underlying assumptions of the classical weakly coupled H-aggregate (WCH) model. We find that, while this model sufficiently describes the degree of aggregation in homogenous systems, it does not for heterogenous systems. A modified model is then proposed that better accounts for multiple emissive species (MES). Within this work, we show the residual monomeric chains must be accounted for to properly assign either H- or J-type aggregation. We next attempted to determine the impact of the solvation environment on the polymer chain conformation. Specifically, we analyze the properties that classify a solvent as either “good” or “poor” for a given polymer. The results from solvent poisoning with both a higher dielectric constant and lower dielectric constant solvent show that while this property along with the polarizability of the environment do impact the photophysical properties, they do not fully describe the differences. We then show the emission heterogeneity is retained when pre-aggregated samples undergo a phase transition from solution to solid. Moreover, we find an enhancement of the emission intensity in the aggregated samples compared to that of the monomer intensity. Finally, we show the general utility of the FCS method combined with the MES model for understanding the spectra of a variety of other conjugated polymers.
Hybride Vorgehensmodelle und Lean Methoden in global verteilten Produktentwicklungsprojekten

description: Wettbewerbsvorteile erzielen vor allem Unternehmen, die schneller als ihre Wettbewerber auf Veränderungen von Märkten, Kunden und Technologien reagieren. Dies erfordert insbesondere
in der Produktentwicklung eine hohe Flexibilität, weshalb Unternehmen von klassischen zu agilen bzw. hybriden Vorgehensmodellen wechseln und diese zusätzlich mit Lean Methoden unterstützen. Darüber hinaus konzentrieren sich Unternehmen zunehmend auf ihre Kernkompetenzen und kaufen je nach Projektbedarf Sekundärkompetenzen mittels Kooperationen ein. Somit wird die Produktentwicklung vermehrt kooperativ in global verteilten Teams durchgeführt. In diesem Zusammenhang stellt die übergeordnete Steuerung der hybriden Teilprojekte zwischen den global verteilten Teams eine Herausforderung für das Projektmanagement dar. Derzeit gibt es keine ganzheitliche Methode für die flexible Vernetzung von Geschäftsprozessen in hybriden Produktentwicklungsprojekten. Die flexible Vernetzung und die damit verbundene automatisierte Ermittlung von Prozesskennzahlen in global verteilten, hybriden Projekten kann die Projektsteuerung vereinfachen. Dieser Beitrag illustriert die Problematik anhand eines Praxisbeispiels und motiviert die Notwendigkeit für eine flexible Vernetzung von Geschäftsprozessen.

description: Recent results on the numerical analysis of algebraic flux correction (AFC) finite element schemes for scalar convection–diffusion equations are reviewed and presented in a unified way. A general form of the method is presented using a link between AFC schemes and nonlinear edge-based diffusion schemes. Then, specific versions of the method, that is, different definitions for the flux limiters, are reviewed and their main results stated. Numerical studies compare the different versions of the scheme.

description: Catalysts applied in cobalt-catalyzed cyclotrimerizations reactions in general rely on the use of Co(I) precatalysts or the in situ generation of Co(I) catalysts from Co(II) sources by reduction in the presence of steering ligands, often by addition of less noble metals. In this paper, we report the synthesis and properties of novel stable CpCo(III) complexes as precatalysts and their exemplary evaluation for application in catalytic [2+2+2] cycloadditions. The role of phosphite neutral ligands, as well as iodide and cyanide as anionic ligands, on the reactivity of the complexes was evaluated. A modified one-pot approach to the synthesis of Cp ring-functionalized Cp’Co(III) complexes was developed. The investigations demonstrated that CpCo(III) complexes can be directly applied as catalysts in catalytic cyclotrimerizations of triynes without reducing agents as additives. © 2021 by the authors.

description: The presented paper examines variability of characteristics of snow cover (snow cover depth, number of days with snow cover and dates of beginning and end of snow cover) and frost depth in Potsdam. The study makes use of a unique long time series of data from the secular meteorological station in Potsdam (Germany), covering the time interval from 1893 to date. The observed behaviour of time series of snow is complex, and not easy to interpret. Even if shrinking snow cover is typically expected in the warming climate of the moderate zone, the change in Potsdam is largely dominated by inter-winter and intra-winter variability, rendering trend detection difficult. Nevertheless, an increasing, statistically significant trend for winter precipitation was detected with almost no changes in the snow fall. A statistical link between the NAO index and the snow cover depth as well as the number of snow cover days was found.

description: We study the inference of long-range correlations by means of Detrended Fluctuation Analysis (DFA) and argue that power-law scaling of the fluctuation function and thus long-memory may not be assumed a priori but have to be established. This requires the investigation of the local slopes. We account for the variability characteristic for stochastic processes by calculating empirical confidence regions. Comparing a long-memory with a short-memory model shows that the inference of long-range correlations from a finite amount of data by means of DFA is not specific. We remark that scaling cannot be concluded from a straight line fit to the fluctuation function in a log-log representation. Furthermore, we show that a local slope larger than α=0.5 for large scales does not necessarily imply long-memory. We also demonstrate, that it is not valid to conclude from a finite scaling region of the fluctuation function to an equivalent scaling region of the autocorrelation function. Finally, we review DFA results for the Prague temperature data set and show that long-range correlations cannot not be concluded unambiguously.
