description: One might expect light to be scattered when it passes through a gravitational wave, and might hope that in favourable circumstances these scatterings could be observed on Earth even if the interaction occurs far away. Damour and Esposito-Farèse, and Kopeikin, Schäfer, Gwinn and Eubanks, found that there were cancellations making such effects disappointingly small. Here I show that those cancellations depend on the emission of the light occurring far behind the gravity-wave source; for light-emissions near that source, larger effects are possible. I first develop a covariant treatment of the problem in exact general relativity (the propagation of light being modelled by geometric optics), and then specialise to linearised gravity. The most promising candidates identified here for detection in the not-too-distant future would involve sufficiently tight binaries as sources of gravitational radiation, and nearby pulsars as light-sources. In some favourable but not extreme cases, I find offsets in the pulses' times of arrival at Earth by ~ 10^{-10} -- 10^{-9} s, with periods half the binaries' periods.

description: Es wurde ein Verfahren vorgestellt, welches es ermöglicht, ein Material aus mehreren Lagen von anisotrop leitfähigen Schichten mit der Momentenmethode numerisch zu modellieren. Dieses Verfahren kann unter anderem dazu eingesetzt werden, um die elektromagnetischen Felder in der Umgebung von Carbonfaser-Kompositwerkstoffe (CFK)-Strukturen zu simulieren. Weiterhin wurde eine Beispielanordnung betrachtet, um das vorgestellte Verfahren zu validieren und um einige prinzipielle Aussagen treffen zu können. Wie zu erwarten, führt eine Verringerung der Schichtdicke oder der Leitfähigkeit zu einer Verschlechterung der Schirmwirkung. Um einen möglichst guten Schirm aus CFK herzustellen, sollte die Orientierung der Fasern der verschiedenen Schichten so gewählt werden, dass eine möglichst isotrope Schirmwirkung entsteht. Ansonsten wäre die erzielte Schirmwirkung sehr stark von der Polarisation des einfallenden Feldes abhängig. Für ein Material aus mehreren Schichten mit unterschiedlicher Faser-Orientierung besteht Grund zu der Annahme, dass sich das Verbundmaterial in einem breiten Frequenzbereich durch eine effektive, isotrope Leitfähigkeit beschreiben lässt.

description: The unoccupied states in topological insulators Bi_2Se_3, PbSb_2Te_4, and Pb_2Bi_2Te_2S_3 are studied by the density functional theory methods. It is shown that a surface state with linear dispersion emerges in the inverted conduction band energy gap at the center of the surface Brillouin zone on the (0001) surface of these insulators. The alternative expression of Z_2 invariant allowed us to show that a necessary condition for the existence of the second Gamma Dirac cone is the presence of local gaps at the time reversal invariant momentum points of the bulk spectrum and change of parity in one of these points.

description: The line shapes of giant dipole resonance (GDR) in the decay of the compound nucleus $^{88}$Mo, which is formed after the fusion-evaporation reaction $^{48}$Ti + $^{40}$Ca at various excitation energies $E^{*}$ from 58 to 308 MeV, are generated by averaging the GDR strength functions predicted within the phonon damping model (PDM) using the empirical probabilities for temperature and angular momentum. The average strength functions are compared with the PDM strength functions calculated at the mean temperature and mean angular momentum, which are obtained by averaging the values of temperature and angular momentum using the same temperature and angular-momentum probability distributions, respectively. It is seen that these two ways of generating the GDR linear line shape yield very similar results. It is also shown that the GDR width approaches a saturation at angular momentum $J\geq$ 50$\hbar$ at $T=$ 4 MeV and at $J\geq$ 70$\hbar$ at any $T$.

description: Die Prüfung der Störfestigkeit gegenüber transienter Störvorgänge, wie sie zurzeit in der ISO 7637 definiert ist, führt des Öfteren zu unterschiedlichen Ergebnissen in der Prüflingsbewertung. Die Ursache dieser Abweichungen lieg aber nicht am Prüfling oder dem Messaufbau selbst, sondern ist in erster Linie den Generatoren, vor allen den darin verbauten unterschiedlichen Netzwerken zur Erzeugung und Entkopplung der Testpulse zuzuschreiben. Die im Rahmen einer durchgeführten Generatorverifikation ermittelten Ergebnisse zeigen deutlich, dass sich abhängig vom Generatortyp zum Teil erhebliche Unterschiede in den Messergebnissen zwischen den Geräten zeigen, vor allem wenn die Belastungen vom standardisierten Verifikationssetup abweichen. Dies kann zur Folge haben, dass im Entwicklungsbetrieb widersprüchliche Ergebnisse generiert werden, die zu Fehlentwicklungen und in der Folge zu zusätzlichen Redesigns und Entwicklungsiterationen führen. Im schlimmsten Fall können unterschiedliche Produktbewertungen von verschiedenen EMV-Testlaboren desselben Prüflings erhebliche Probleme in Geschäftsbeziehungen verursachen. Aus dem Grund lässt sich ein Analyse- und Handlungsbedarf ableiten, um aus standardisierten Pulsstörfestigkeitstests auch verlässlich vergleichbare Ergebnisse zu erhalten.

air quality

description: A regional modeling system that integrates the state-of-the-art emissions processing (SMOKE), climate (CWRF), and air quality (CMAQ) models has been combined with satellite measurements of fire activities to assess the impact of fire emissions on the contiguous United States (CONUS) air quality during 1997–2016. The system realistically reproduced the spatiotemporal distributions of the observed meteorology and surface air quality, with a slight overestimate of surface ozone (O3) by ~4% and underestimate of surface PM2.5 by ~10%. The system simulation showed that the fire impacts on primary pollutants such as CO were generally confined to the fire source areas but its effects on secondary pollutants like O3 spread more broadly. The fire contribution to air quality varied greatly during 1997-2016 and occasionally accounted for more than 100 ppbv of monthly mean surface CO and over 20 µg m−3 of monthly mean PM2.5 in the Northwest U.S. and Northern California, two regions susceptible to frequent fires. Fire emissions also had implications on air quality compliance. From 1997 to 2016, fire emissions increased surface 8-hour O3 standard exceedances by 10% and 24-hour PM2.5 exceedances by 33% over CONUS.

description: With the aim of establishing a criterion for identifying when a lipid bilayer has reached steady state using the molecular dynamics simulation technique, lipid bilayers of different composition in their liquid crystalline phase were simulated in aqueous solution in presence of CaCl$_2$ as electrolyte, at different concentration levels. In this regard, we used two different lipid bilayer systems: one composed by 288 DPPC (DiPalmitoylPhosphatidylCholine) and another constituted by 288 DPPS (DiPalmitoylPhosphatidylSerine). In this sense, for both type of lipid bilayers, we have studied the temporal evolution of some lipids properties, such as the surface area per lipid, the deuterium order parameter, the lipid hydration and the lipid-calcium coordination. From their analysis, it became evident how each property has a different time to achieve equilibrium. The following order was found, from faster property to slower property: coordination of ions $\approx$ deuterium order parameter $>$ area per lipid $\approx$ hydration. Consequently, when the hydration of lipids or the mean area per lipid are stable, we can ensure that the lipid membrane has reached the steady state.

Backus-Gilbert inversion algorithm

description: One of the limitations in using spaceborne, microwave radiometer data for atmospheric remote sensing is the nonuniform spatial resolution. Remapping algorithms can be applied to the data to ameliorate this limitation. In this paper, two remapping algorithms, the Backus–Gilbert inversion (BGI) technique and the filter algorithm (AFA), widely used in the operational data preprocessing of the Advanced Technology Microwave Sounder (ATMS), are investigated. The algorithms are compared using simulations and actual ATMS data. Results show that both algorithms can effectively enhance or degrade the resolution of the data. The BGI has a higher remapping accuracy than the AFA. It outperforms the AFA by producing less bias around coastlines and hurricane centers where the signal changes sharply. It shows no obvious bias around the scan ends where the AFA has a noticeable positive bias in the resolution-enhanced image. However, the BGI achieves the resolution enhancement at the expense of increasing the noise by 0.5 K. The use of the antenna pattern instead of the point spread function in the algorithm causes the persistent bias found in the AFA-remapped image, leading not only to an inaccurate antenna temperature expression but also to the neglect of the geometric deformation of the along-scan field-of-views.
Sanctifying Domestic Space and Domesticating Sacred Space: Reading Ziyāra and Taṣliya in Light of the Domestic in the Early Modern Ottoman World

description: Shrine-visitation (ziyāra) and devotion to Muḥammad (such as expressed in taṣliya, the uttering of invocations upon the Prophet), both expressed through a range of ritualized practices and material objects, were at the heart of everyday Islam for the vast majority of early modern Ottoman Muslims across the empire. While both bodies of practice had communal and domestic aspects, this article focuses on the important intersections of the domestic with both shrine-visitation and Muḥammad-centered devotion as visible in the early modern Ottoman lands, with a primary emphasis on the eighteenth century. While saints’ shrines were communal and ‘public’ in nature, a range of attitudes and practices associated with them, recoverable through surviving physical evidence, travel literature, and hagiography, reveal their construction as domestic spaces of a different sort, appearing to pious visitors as the ‘home’ of the entombed saint through such routes as wall-writing, gender-mixing, and dream encounters. Devotion to Muḥammad, on the other hand, while having many communal manifestations, was also deeply rooted in the domestic space of the household, in both prescription and practice. Through an examination of commentary literature, hagiography, and imagery and objects of devotion, particularly in the context of the famed manual of devotion Dalā’il al-khayrāt, I demonstrate the transformative effect of such devotion upon domestic space and the ways in which domestic contexts were linked to the wider early modern world, Ottoman, and beyond.

description: Systems with different interactions could develop the same critical behaviour due to the underlying symmetry and universality. Using this principle of universality, we can embed critical correlations modeled on the 3D Ising model into the simulated data of heavy-ion collisions, hiding weak signals of a few inter-particle correlations within a large particle cloud. Employing a point cloud network with dynamical edge convolution, we are able to identify events with critical fluctuations through supervised learning, and pick out a large fraction of signal particles used for decision-making in each single event.

description: Currently, there are challenges with proper disposal of cassava processing wastewater, and a need for sustainable energy in the cassava industry. This study investigated the impact of co-digestion of cassava wastewater (CW) with livestock manure (poultry litter (PL) and dairy manure (DM)), and porous adsorbents (biochar (B-Char) and zeolite (ZEO)) on energy production and treatment efficiency. Batch anaerobic digestion experiments were conducted, with 16 treatments of CW combined with manure and/or porous adsorbents using triplicate reactors for 48 days. The results showed that CW combined with ZEO (3 g/g total solids (TS)) produced the highest cumulative CH4 (653 mL CH4/g VS), while CW:PL (1:1) produced the most CH4 on a mass basis (17.9 mL CH4/g substrate). The largest reduction in lag phase was observed in the mixture containing CW (1:1), PL (1:1), and B-Char (3 g/g TS), yielding 400 mL CH4/g volatile solids (VS) after 15 days of digestion, which was 84.8% of the total cumulative CH4 from the 48-day trial. Co-digesting CW with ZEO, B-Char, or PL provided the necessary buffer needed for digestion of CW, which improved the process stability and resulted in a significant reduction in chemical oxygen demand (COD). Co-digestion could provide a sustainable strategy for treating and valorizing CW. Scale-up calculations showed that a CW input of 1000–2000 L/d co-digested with PL (1:1) could produce 9403 m3 CH4/yr using a 50 m3 digester, equivalent to 373,327 MJ/yr or 24.9 tons of firewood/year. This system would have a profit of $5642/yr and a $47,805 net present value.

Democratic Republic of Congo (DRC)

description: Shifting cultivation has been shown to be the primary cause of land use change in the Democratic Republic of Congo (DRC). Traditionally, forested and fallow land are rotated in a slash and burn cycle that has created an agricultural mosaic, including secondary forest, known as the rural complex. This study investigates the land use context of new forest clearing (during 2000–2015) in primary forest areas outside of the established rural complex. These new forest clearings occur as either rural complex expansion (RCE) or isolated forest perforations (IFP), with consequent implications on the forest ecosystem and biodiversity habitat. During 2000–2015, subsistence agriculture was the dominant driver of forest clearing for both extension of settled areas and pioneer clearings removed from settled areas. Less than 1% of clearing was directly attributable to land uses such as mining, plantations, and logging, showing that the impact of commercial operations in the DRC is currently dwarfed by a reliance on small-holder shifting cultivation. However, analyzing the landscape context showed that large-scale agroindustry and resource extraction activities lead to increased forest loss and degradation beyond their previously-understood footprints. The worker populations drawn to these areas create communities that rely on shifting cultivation and non-timber forest products (NTFP) for food, energy, and building materials. An estimated 12% of forest loss within the RCE and 9% of the area of IFP was found to be within 5 km of mines, logging, or plantations. Given increasing demographic and commercial pressures on DRC’s forests, it will be crucial to factor in this landscape-level land use change dynamic in land use planning and sustainability-focused governance.

description: Mit dem steigenden Grad der Elektrifizierung des Antriebsstrangs moderner Kraftfahrzeuge und durch den Einsatz immer leistungsstärkerer Umrichter und Maschinen nimmt das elektrische Störpotential innerhalb des Gesamtsystems Kraftfahrzeug beständig zu. Insbesondere durch die vom Umrichter zu liefernden hohen Spannungen und Leistungen, mit PWM-Frequenzen von 20 kHz und mehr, sowie durch die Ein- und Ausschaltvorgänge steigt das Störpotential von transienten Vorgängen im Gesamtbordnetz deutlich an. Als besonders kritisch sind hierbei die Rückwirkungen auf das Hochvolt-DC-Bordnetz (HVDC) zu betrachten, da diese sich über den Koppelpfad der verschiedenen DC/DC-Wandler, beispielsweise, leicht auf das Niedervolt-DC-Bordnetz (LVDC) übertragen können. Dort können die hochenergetischen Transienten sowohl direkt - leitungs-gebunden - zu Störungen in der Elektronik führen, als auch indirekt über elektromagnetische Abstrahlung durch die nicht geschirmten Leitungen im LVDC-Bordnetz. Diese Störpotentiale müssen daher genau analysiert werden, um Gegenmaßnahmen entwickeln und bewerten zu können. Entsprechende standardisierte Messverfahren werden, zum Beispiel, durch die Normen ISO 7637 [ISO 7637 (Draft-Standard), "Road Vehicle - Electrical distiurbance by conducting and coupling", September 2012] und CISPR25 [CISPR25 (Technical Standard), Radio disturbance characteristics for the protection of receivers used on board vehicles, boats and on devices - Limits and methods of measurement, 3rd ed. Hrsg., 2009] definiert. Da diese Messungen oft sehr zeit- und kostenintensiv sind, besonders wenn sie wiederholt an Hardwareprototypen durchgeführt werden müssen, bietet es sich an Vorabanalysen simulationsgestützt durchzuführen, um neue Komponenten oder Maßnahmen schnell bewerten zu können. Hierfür werden hinreichend präzise Simulationsmodelle der beteiligten Komponenten und des Gesamtsystems benötigt.

description: We present the first experimental realization of a two-dimensional quantum gas in a purely magnetic trap dressed by a radio frequency field in the presence of gravity. The resulting potential is extremely smooth and very close to harmonic in the two-dimensional plane of confinement. We fully characterize the trap and demonstrate the confinement of a quantum gas to two dimensions. The trap geometry can be modified to a large extent, in particular in a dynamical way. Taking advantage of this possibility, we study the monopole and the quadrupole modes of a two-dimensional Bose gas.

description: Surface downward shortwave radiation (DSR) and photosynthetically active radiation (PAR), its visible component, are key parameters needed for many land process models and terrestrial applications. Most existing DSR and PAR products were developed for climate studies and therefore have coarse spatial resolutions, which cannot satisfy the requirements of many applications. This paper introduces a new global high-resolution product of DSR (MCD18A1) and PAR (MCD18A2) over land surfaces using the MODIS data. The current version is Collection 6.0 at the spatial resolution of 5 km and two temporal resolutions (instantaneous and three-hour). A look-up table (LUT) based retrieval approach was chosen as the main operational algorithm so as to generate the products from the MODIS top-of-atmosphere (TOA) reflectance and other ancillary data sets. The new MCD18 products are archived and distributed via NASA’s Land Processes Distributed Active Archive Center (LP DAAC). The products have been validated based on one year of ground radiation measurements at 33 Baseline Surface Radiation Network (BSRN) and 25 AmeriFlux stations. The instantaneous DSR has a bias of −15.4 W/m2 and root mean square error (RMSE) of 101.0 W/m2, while the instantaneous PAR has a bias of −0.6 W/m2 and RMSE of 45.7 W/m2. RMSE of daily DSR is 32.3 W/m2, and that of the daily PAR is 13.1 W/m2. The accuracy of the new MODIS daily DSR data is higher than the GLASS product and lower than the CERES product, while the latter incorporates additional geostationary data with better capturing DSR diurnal variability. MCD18 products are currently under reprocessing and the new version (Collection 6.1) will provide improved spatial resolution (1 km) and accuracy.

description: Im Rahmen dieser Arbeit wurde die Schutzwirkung von IT-Schaltnetzteilen gegenüber leitungsgeführten Störungen auf der Netzspannung untersucht. Es zeigte sich, dass die verschiedenen eingekoppelten Störsignale auf der Netzspannung durch das Netzteil auf die Ausgangsleitungen koppeln. Hierfür ist ein ein- oder ausgeschaltetes Netzteil nicht von großer Bedeutung, da die gemessenen Signale sich teilweise nur geringfügig voneinander unterschieden. Bei Frequenzen oberhalb von 300 MHz wurde durch die Eingangsfilterstufe des Netzteils der Großteil herausgefiltert. Unterhalb von 300 MHz war eine eindeutige Übertragung des Störsignals vom Ein- zum Ausgang zu erkennen. Des Weiteren ergab sich bei jedem Störsignalen ein Grenzwert, bei dem die Überspannungsschutzfunktion des Netzteils zum bewussten ausschalten führte. Größtenteils schaltete sich das Netzteils nach der Deaktivierung der Störquelle wieder von selbst ein, außer bei dem doppelt exponentiellen Puls. Hier musste das Netzteil vom Netz getrennt werden und war danach wieder einsatzbereit. Es ist daher möglich über eine bewusste Störung auf der Netzleitung, ein IT-Netzteil ohne dessen Zerstörung auszuschalten. Über einen Burst-Signal kann das IT-System in den Zustand des ständigen Ein- und Ausschalten gebracht werden. Was sich negativ auf die Hardware nach dem Netzteil auswirken könnte. Somit schützt ein Netzteil vor Frequenzen über 300 MHz, ist aber im Frequenzbereich von 0 bis 100 MHz anfällig auf Störungen, die auf die Ausgänge koppelt und so weiteren Schaden verursachen könnte.

description: We consider accumulation of periodic points in local uniformly quasiregular dynamics. Given a local uniformly quasiregular mapping $f$ with a countable and closed set of isolated essential singularities and their accumulation points on a closed Riemannian manifold, we show that points in the Julia set are accumulated by periodic points. If, in addition, the Fatou set is non-empty and connected, the accumulation is by periodic points in the Julia set itself. We also give sufficient conditions for the density of repelling periodic points.

description: We develop a theoretical model of the surface plasmon resonance of metallic nanospheres in the size range down to the single nanometer size. Within this model we explicitly show how different microscopic mechanisms, namely quantization due to size (QSE) and electron spill-out, affect the energy of the surface plasmon. We demonstrate, that electron spill-out effects, which can move the surface plasma energy both toward the red or the blue, can be comparable to or even stronger than QSE. Thus, depending on circumstances, QSE may only be observed for ultrasmall metal nanoparticles much closer to 1 nm in size than to 10 nm. Results presented herein are in quantitative agreement with recent published experimental results for Ag and Au.

description: Im CISPR wurde vor einigen Jahren beschlossen, für die Erstellung einer Norm zur Validierung von Messplätzen für die CISPR 25 eine gemeinsame Arbeitsgruppe mit CISPR D und CISPR A zu gründen. Diese gemeinsame Arbeitsgruppe wurde vor einigen Jahren installiert. Parallel dazu wurde in Deutschland ein gemeinsamer Arbeitskreis zwischen dem UK 14 und UK 4 gegründet (April 2008). Ziel dieser Arbeitsgruppen ist es, für die CISPR 25 einen Standard für die Validierung von Absorberhallen mit integriertem Prüftisch zu entwickeln. Da dieser Prüftisch eine ground plane (metallische Auflage) besitzt, wird sich die Validierung dieser Anordnung stark von der normalen Absorberhallen Validierung unterscheiden. In den Arbeitskreisen wurde ein Entwurf erarbeitet. In diesem Beitrag wurden Messungen gemäß dem letzten Stand auf verschiedenen Messplätzen durchgeführt und verglichen. Es soll herausgearbeitet werden, wie die Kalibrierung des Messaufbaues und die verschiedenen Möglichkeiten der Erdung des Messtisches auf die Messergebnisse einwirken und welche Herausforderungen gelöst werden müssen.

description: Für die Störaussendungsmessung von Kraftfahrzeugen ist in der internationalen Norm CISPR 12 festgelegt, dass diese Messungen auf einem im Freien gelegenen Messplatz (en: outdoor test site, OTS) durchzuführen sind. Alternativ dazu können Absorberräume (en: absorber lined shielded enclosure, ALSE) genutzt werden, wenn die Ergebnisse denen entsprechen, die auf einer OTS gewonnen werden. Dazu sind derzeit im zuständigen Gremium CIPSR/D Validierungsverfahren in Beratung. Die Eignung eines möglichen Validierungsverfahrens ist in [C. Schwing, H. Hirsch et al., "Validierung von Messplätzen für Störaussendungsmessungen von Fahrzeugen nach CISPR 12", Elektromagnetische Verträglichkeit emv 2012, VDE VERLAG GMBH Berlin, 2012, pp. 273-280] dargestellt worden. Um für das Validierungsverfahren passende Grenzwerte zu definieren, müssen die Unterschiede der Messplätze herausgearbeitet und verstanden sein. Dazu bietet sich die Korrelation von Messverfahren nach CISPR 16-4-5 TR [IEC Technical Report CISPR 16-4-5, "Conditions for the use of alternative test methods"] an. In [C. Schwing, H. Hirsch, "Investigation of CISPR 12 test sites", Conference Proceedings EMC Europe 2012, Rome, doi: 10.1109/EMCEurope.2012.6396660] und [C. Schwing, H. Hirsch, " Validation of CISPR 12 test sites ", Conference Proceedings EMC Europe 2013, Brugge, ISSN 2325-0356, pp. 316-320] ist anhand von realen Messungen sowie numerischer Feldsimulationen gezeigt worden, dass Unterschiede zwischen den Messplätzen aufgrund unterschiedlicher Bodenparameter existieren. Im Folgenden wird die Korrelation von ALSE und OTS, im Hinblick auf die Abweichung des jeweiligen Messplatzes zu einer definierten Referenzgröße untersucht. Diese physikalische Referenzgröße ist ein Maß für das Störpotential eines Prüflings hinsichtlich des Funkschutzes.
Headedness and the Lexicon: The Case of Verb-to-Noun Ratios

description: This paper takes a well-known observation as its starting point, that is, languages vary with respect to headedness, with the standard head-initial and head-final types well attested. Is there a connection between headedness and the size of a lexical class? Although this question seems quite straightforward, there are formidable methodological and theoretical challenges in addressing it. Building on initial results by several researchers, we refine our methodology and consider the proportion of nouns to simplex verbs (as opposed to light verb constructions) in a varied sample of 33 languages to evaluate the connection between headedness and the size of a lexical class. We demonstrate a robust correlation between this proportion and headedness. While the proportion of nouns in a lexicon is relatively stable, head-final/object-verb (OV)-type languages (e.g., Japanese or Hungarian) have a relatively small number of simplex verbs, whereas head-initial/verb-initial languages (e.g., Irish or Zapotec) have a considerably larger percentage of such verbs. The difference between the head-final and head-initial type is statistically significant. We, then, consider a subset of languages characterized as subject-verb-object (SVO) and show that this group is not uniform. Those SVO languages that have strong head-initial characteristics (as shown by the order of constituents in a set of phrases and word order alternations) are characterized by a relatively large proportion of lexical verbs. SVO languages that have strong head-final traits (e.g., Mandarin Chinese) pattern with head-final languages, and a small subset of SVO languages are genuinely in the middle (e.g., English, Russian). We offer a tentative explanation for this headedness asymmetry, couched in terms of informativity and parsing principles, and discuss additional evidence in support of our account. All told, the fewer simplex verbs in head-final/OV-type languages is an adaptation in response to their particular pattern of headedness. The object-verb/verb-object (OV/VO) difference with respect to noun/verb ratios also reveals itself in SVO languages; some languages, Chinese and Latin among them, show a strongly OV ratio, whereas others, such as Romance or Bantu, are VO-like in their noun/verb ratios. The proportion of nouns to verbs thus emerges as a new linguistic characteristic that is correlated with headedness.
Hamilton-Jacobi-Bellman-Isaacs equation for rational inattention in the long-run management of river environments under uncertainty

description: A new stochastic control model for the long-run environmental management of rivers is mathematically and numerically analyzed, focusing on a modern sediment replenishment problem with unique nonsmooth and nonlinear properties. Rational inattention as a novel adaptive strategy to collect information and intervene against the target system is modeled using Erlangization. The system dynamics containing the river discharge following a continuous-state branching with an immigration-type process and the controlled sediment storage dynamics lead to a nonsmooth and nonlocal infinitesimal generator. Modeling uncertainty, which is ubiquitous in certain applications, is considered in a robust control framework in which deviations between the benchmark and distorted models are penalized through relative entropy. The partial integro-differential Hamilton-Jacobi-Bellman-Isaacs (HJBI) equation as an optimality equation is derived, and its uniqueness, existence, and optimality are discussed. A monotone finite difference scheme guaranteeing the boundedness and uniqueness of numerical solutions is proposed to discretize the HJBI equation and is verified based on manufactured solutions. Model applications are also conducted with the parameter values identified from the available data and physical formulae. The computational results suggest that environmental management should be rationally inattentive in a state-dependent and adaptive manner.
A Deep Adversarial Approach Based on Multi-Sensor Fusion for Semi-Supervised Remaining Useful Life Prognostics

description: Multi-sensor systems are proliferating in the asset management industry. Industry 4.0, combined with the Internet of Things (IoT), has ushered in the requirements of prognostics and health management systems to predict the system’s reliability and assess maintenance decisions. State of the art systems now generate big machinery data and require multi-sensor fusion for integrated remaining useful life prognostic capabilities. When dealing with these data sets, traditional prediction methods are not equipped to handle the multiple sensor signals in unison. To address this challenge, this paper proposes a new, deep, adversarial approach to any remaining useful life prediction in which a novel, non-Markovian, variational, inference-based model, incorporating an adversarial methodology, is derived. To evaluate the proposed approach, two public multi-sensor data sets are used for the remaining useful life prediction applications: (1) CMAPSS turbofan engine dataset, and (2) FEMTO Pronostia rolling element bearing data set. The proposed approach obtains favorable results when against similar deep learning models.

description: We carefully investigate the modified Einstein's field equation in a four dimensional (3-brane) arbitrary manifold embedded in a five dimensional Non-Riemannian bulk spacetime with a noncompact extra dimension. In this context the Israel-Darmois matching conditions are extended assuming that the torsion in the bulk is continuous. The discontinuity in the torsion first derivatives are related to the matter distribution through the field equation. In addition, we develop a model that describes a flat FLRW model embedded in a 5-dimensional de Sitter or Anti de Sitter, where a 5-dimensional cosmological constant emerges from the torsion.
