description: A series of carbazole based sensitizers with either phenyl based donors (TBC, TMC, OMC, PC, TBR, TMR, OMR and PR) or aryl amine based donors (OMNC, CNC and HNC) as well as one without a donor group (CC) have been synthesized to understand the influence of the strength of the donor moiety on the optical, electrochemical and photovoltaic properties. Two different acceptor moieties such as cyano acrylic acid and rhodanine acetic acid were introduced and evaluated. Different substituents on the phenyl group have a significant impact on the light harvesting ability of the sensitizers. Among phenyl based donors, anisole based carbazole (OMC) shows the highest short circuit current (JSC) of 4.96 mA cm−2 with overall power conversion efficiency (PCE) of 2.69%. In the case of the sensitizers with aryl amine based donors, the increasing bulkiness of the donor group lead to increasing open circuit potential. Transient photocurrent and photovoltage measurements signify the importance of a bulky donor fragment in determining the open circuit potential of the dyes. Sensitizers with hexyloxy substituted phenyl amine as the donor group shows a JSC of 6.84 mA cm−2 with PCE of 3.33%. The overall investigation provides vital information about the influence of donor groups on the optoelectronic properties of the sensitizers for its photovoltaic applications.

description: A study was conducted to evaluate the effects on the development of root rot on common bean, cv. 'Dufrix' after treatment with four volumes of water (0, 30%, 60%, and 90%, v/w) added to rice grains previously immersed in water for 24 hours before autoclaving and colonization of grains by Rhizoctonia solani AG-4. Colonized rice grains and non-infested rice grains were mixed in pots with sterilized soil and sand (2:1), where beans were sown. Based on results of area under plant emergence curve, plant height, plant dry weight, and disease severity, we conclude that inoculum is more effective in causing disease when no water is added to the rice grains before autoclaving.

description: Acquisition of new catalytic activity is a relatively rare evolutionary event. A striking example appears in the pathway to the antibiotic lankacidin, as a monoamine oxidase (MAO) family member, LkcE, catalyzes both an unusual amide oxidation, and a subsequent intramolecular Mannich reaction to form the polyketide macrocycle. We report evidence here for the molecular basis for this dual activity. The reaction sequence involves several essential active site residues and a conformational change likely comprising an interdomain hinge movement. These features, which have not previously been described in the MAO family, both depend on a unique dimerization mode relative to all structurally characterized members. Taken together, these data add weight to the idea that designing new multifunctional enzymes may require changes in both architecture and catalytic machinery. Encouragingly, however, our data also show LkcE to bind alternative substrates, supporting its potential utility as a general cyclization catalyst in synthetic biology.

description: Southeast Asia has been experiencing unprecedented economic growth propelled by thriving production and service sectors, rapid urbanization, extensive digitalization, and a growing young population. However, issues such as regional disparities in economic and social indicators cannot be ignored. For instance, while urban areas enjoy new-found opportunities, their rural counterparts lag behind. Frequent natural disasters and natural resource degradation due to illegal logging and over exploitation have added further pressure on the rural poor. Additionally, the effects of the recent economic slowdown due to COVID-19 have also trickled to the rural areas. Forced unemployment of rural migrants in the cities, increased financial instability and weaker agricultural supply chains have aggravated their vulnerability to poverty. The region is at a crucial crossroad – facing challenges that need to be addressed, but also opportunities that herald a better future for individuals and the countries alike. Against this background, the overall objective of this thesis is to provide a better understanding of decision-making, especially amongst rural populations in Thailand and Vietnam. In particular, the thesis investigates (i) who is an internal migrant, (ii) how do environmental shocks impact migration decisions, (iii) what predicts the duration of stay of migrants in the city and their migration intensity, (iv) what are the determinants and motivations behind migrant remittances, (v) can the Big Five Model of personality traits be validated in rural Southeast Asia, (vi) what role do non-cognitive skills play in occupational outcomes, (vii) what determines internet usage amongst migrants, and, (viii) how are food consumption patterns changing in Vietnam and what are its environmental effects.

description: Variability effects in graphene can result from the surrounding environment and the graphene material itself, which form a critical issue in examining the feasibility of graphene devices for large-scale production. From the reliability and yield perspective, these variabilities cause fluctuations in the device performance, which should be minimized via device engineering. From the metrology perspective, however, the variability effects can function as novel probing mechanisms, in which the 'signal fluctuations' can be useful for potential sensing applications. This paper presents an overview of the variability effects in graphene, with emphasis on their challenges and opportunities for device engineering and applications. The discussion can extend to other thin-film, nanowire and nanotube devices with similar variability issues, forming general interest in evaluating the promise of emerging technologies.

description: Agricultural intensification often leads to fragmentation of natural habitats, such as forests, and thereby negatively affects forest specialist species. However, human introduced habitats, such as hedges, may counteract negative effects of forest fragmentation and increase dispersal, particularly of forest specialists. We studied effects of habitat type (forest edge versus hedge) and hedge isolation from forests (connected versus isolated hedge) in agricultural landscapes on abundance, species richness and community composition of mice, voles and shrews in forest edges and hedges. Simultaneously to these effects of forest edge/hedge type we analysed impacts of habitat structure, namely percentage of bare ground and forest edge/hedge width, on abundance, species richness and community composition of small mammals. Total abundance and forest specialist abundance (both driven by the most abundant species Myodes glareolus, bank vole) were higher in forest edges than in hedges, while hedge isolation had no effect. In contrast, abundance of habitat generalists was higher in isolated compared to connected hedges, with no effect of habitat type (forest edge versus hedge). Species richness as well as abundance of the most abundant habitat generalist Sorex araneus (common shrew), were not affected by habitat type or hedge isolation. Decreasing percentage of bare ground and increasing forest edge/hedge width was associated with increased abundance of forest specialists, while habitat structure was unrelated to species richness or abundance of any other group. Community composition was driven by forest specialists, which exceeded habitat generalist abundance in forest edges and connected hedges, while abundances were similar to each other in isolated hedges. Our results show that small mammal forest specialists prefer forest edges as habitats over hedges, while habitat generalists are able to use unoccupied ecological niches in isolated hedges. Consequently even isolated hedges can be marginal habitats for forest specialists and habitat generalists and thereby may increase regional farmland biodiversity.

description: If a body of dielectric material is coated by a plasmonic structure of negative dielectric constant with nonzero loss parameter, then cloaking by anomalous localized resonance (CALR) may occur as the loss parameter tends to zero. The aim of this paper is to investigate this phenomenon in two and three dimensions when the coated structure is radial, and the core, shell and matrix are isotropic materials. In two dimensions, we show that if the real part of the permittivity of the shell is -1 (under the assumption that the permittivity of the background is 1), then CALR takes place. If it is different from -1, then CALR does not occur. In three dimensions, we show that CALR does not occur. The analysis of this paper reveals that occurrence of CALR is determined by the eigenvalue distribution of the Neumann-Poincaré-type operator associated with the structure.

description: A physical analysis and mathematical formulation of the structure of an accretion shock wave in the case of young stars are given. Some results are presented, and the dependence of the structure of the shock on various parameters is investigated. In the general case, the relative intensities and profiles of lines in the spectra of T Tauri stars should depend on the velocity and density of the infalling gas, as well as on the accretion geometry. The calculation results may serve as a base for elucidating the nature of the activity of young stars.

description: AKTIVA-MCI is a program for patients with mild cognitive impairment (MCI) that aims to enhance participation in cognitively stimulating leisure activities. Participation in cognitively stimulating activities seems to be a potential strategy for people with MCI delaying cognitive decline for a while. In total, 35 MCI patients were enrolled in the pilot study of whom 29 completed the whole program (16 female, 71.1±7.5 years; Mini Mental Status Examination score: 28±2.2). Daily activity protocols were used to measure the frequency of participation in cognitively stimulating activities during the program (12 sessions). Additional standardized psychometric tests and questionnaires were used to assess cognition, mood, and subjective memory decline. Analyses of the daily activity protocols showed that during the intervention participants increased the frequency of several cognitively stimulating leisure activities. Comparison of pre-post data indicates no changes in cognitive status, mood, and subjective memory decline. These findings indicate that the program is suitable for patients with MCI. © 2017 Tesky et al.

description: The article investigates the properties of the occupational mobility network (OMN) in 12 EU countries. Using REFLEX database we construct for each country an empirical OMN that reflects the job movements of the university graduates, during the first five years after graduation (1999 - 2005). The nodes are represented by the occupations coded at 3 digits according to ISCO-88 and the links are weighted with the number of graduates switching from one occupation to another. We construct the networks as weighted and directed. This comparative study allows us to see what are the common patterns in the OMN over different EU labor markets.

Multiscale Filler Structure in Simplified Industrial Nanocomposite Silica/SBR Systems Studied by SAXS and TEM

description: Simplified silica (Zeosil 1165 MP) and SBR (140k carrying silanol end-groups) nanocomposites have been formulated by mixing of a reduced number of ingredients with respect to industrial applications. The thermo-mechanical history of the samples during the mixing process was monitored and adjusted to identical final temperatures. The filler structure on large scales up to micrometers was studied by transmission electron microscopy (TEM) and very small-angle X-ray scattering (SAXS). A complete quantitative model extending from the primary silica nanoparticle (of radius \approx 10 nm), to nanoparticles aggregates, up to micrometer-sized branches with typical lateral dimension of 150 nm is proposed. Image analysis of the TEM-pictures yields the fraction of zones of pure polymer, which extend between the branches of a large-scale filler network. This network is compatible with a fractal of average dimension 2.4 as measured by scattering. On smaller length scales, inside the branches, small silica aggregates are present. Their average radius has been deduced from a Kratky analysis, and it ranges between 35 and 40 nm for all silica fractions investigated here (ϕ_si = 8-21% vol.). A central piece of our analysis is the description of the interaggregate interaction by a simulated structure factor for polydisperse spheres representing aggregates. A polydispersity of 30% in aggregate size is assumed, and interactions between these aggregates are described with a hard core repulsive potential. The same distribution in size is used to evaluate the polydisperse form factor. Comparison with the experimental intensity leads to the determination of the average aggregate compacity (assumed identical for all aggregates in the distribution, between 31% and 38% depending on ϕ_si), and thus aggregation number (ca. 45, with a large spread). Because of the effect of aggregate compacity and of pure polymer zones, the volume fraction of aggregates is higher in the branches than ϕ_si. The repulsion between aggregates has a strong effect on the apparent isothermal compressibility: it leads to a characteristic low-q depression, which cannot be interpreted as aggregate mass decrease in our data. In addition, the reinforcement effect of these silica structures in the SBR-matrix is characterized with oscillatory shear and described with a model based on the same aggregate compacity. Finally, our results show that it is possible to analyze the complex structure of interacting aggregates in nanocomposites of industrial origin in a self-consistent and quantitative manner.

description: Dans un contexte d’épidémie régionale de rougeole communautaire, une épidémie est survenue dans un des services d’urgences adultes de notre établissement de santé. Objectif. Décrire cette épidémie et d’analyser les actions engagées par l’équipe opérationnelle d’hygiène hospitalière (EOHH) et le service de santé au travail (SST) en identifiant les limites à la mise en œuvre des recommandations nationales. Méthode. Description de l’épidémie. Analyse des écarts par rapport à la circulaire de 2009. Résultats. Admission aux urgences du cas index diagnostiqué le lendemain avec alerte retardée de l’EOHH (recherche et information des patients contacts) et du SST (vérification de l’immunité des agents). Introduction du port du masque pour tout agent aux urgences et rattrapage vaccinal devant la découverte de deux cas chez des professionnels des urgences avec un total de 11 cas nosocomiaux dont 2 cas patients. L’analyse a montré une identification rapide des contacts et des professionnels impliqués mais une alerte trop souvent tardive pour administrer un vaccin ou des immunoglobulines aux cas contacts non immunisés dans le délai requis. Le respect de la confidentialité a compliqué l’investigation chez les professionnels dont l’immunité était largement méconnue. L’éviction des agents contacts non vaccinés a été impossible. Conclusion. La maîtrise de la diffusion de la rougeole en établissement de santé nécessite une alerte précoce, une connaissance du statut vaccinal des professionnels de santé, le respect de l’hygiène respiratoire et une organisation qui assure une prise en charge postexposition dans des délais plus courts.

Subjects: ENSO, impacts, Paddy rice

description: The El Niño Southern Oscillation (ENSO) is a phenomenon of climatic variability, the effects of which can induce changes in temperature and rainfall in different countries of the world. These events impact sectors of great global relevance, such as agriculture. This research estimated the impacts of ENSO on paddy rice yields in fields located in Brazil, China, and Colombia. ENSO impacts on rice production were measured through the differences between the yields of the last two decades of each crop in each phase of ENSO compared to normal climatic conditions. Most of the estimated impacts were slightly negative, with the most significant impacts being those reported in the study region in Brazil and Colombia during the second growing season, whose growth period coincides with the maximum peak of ENSO anomalies.

We also point out that the normalizable "vacuum state" (in the sense defined below) of this model can be understood as spontaneous breaking of the emergent conformal symmetry. We provide an example of an interacting system that couples the "particle" and "ghost" degrees of freedom and nevertheless remains unitary on both classical and quantum level.

description: The oscillation coupling and different nonlinear effects are observed in a single trapped $^{40}Ca^{+}$ ion confined in our home-built surface-electrode trap (SET). The coupling and the nonlinearity are originated from the high-order multipole potentials due to different layouts and the fabrication asymmetry of the SET. We solve a complicated Duffing equation with coupled oscillation terms by the multiple scale method, which fits the experimental values very well. Our investigation in the SET helps for exploring nonlinearity using currently available techniques and for suppressing instability of qubits in quantum information processing with trapped ions.

description: 7Li spin-alignment NMR is used to trace ultraslow diffusion of Li+ in the layered Li conductor LixTiS2 (x=0.7). Two-time correlation functions were recorded for fixed evolution times as a function of mixing time at temperatures within the 7Li rigid-lattice regime. The corresponding decay rates were identified as Li jump rates τ−1 ranging from 10−1to103s−1 between temperatures T=148 K and 213K. The jump rates obtained directly from spin-alignment echo NMR and those from diffusion induced maxima of spin-lattice relaxation peaks, monitored in the laboratory as well as in the rotating frame, are consistent with each other and follow an Arrhenius law with an activation energy of 0.41(1)eV and a preexponential factor of 6.3(1)×1012s−1. Altogether, a solitary Li diffusion process was found between 148 and 510K. Li diffusion was investigated in a dynamic range of about 10 orders of magnitude, i.e., 0.1⩽τ−1⩽7.8×108s−1. Additionally, the analysis of final-state echo amplitudes of the two-time correlation functions revealed information about the Li diffusion pathway in Li0.7TiS2. Obviously, a two-site jump process is present, i.e., besides the regularly occupied octahedral sites also the vacant tetrahedral ones within the van der Waals gap are involved in the overall two-dimensional diffusion process. © 2008 The American Physical Society.

Les résultats permettent de mettre en avant certaines carences, notamment au niveau des moyens organisationnels pour une grande majorité des Ehpad ainsi que pour la formation des agents. L’utilisation des produits n’était pas toujours appropriée. Discussion - Conclusion. L’hygiène bucco-dentaire prothétique (HBDP) est un soin essentiel pour le maintien d’une bonne santé générale. Il ne doit pas être négligé. Après l’analyse des résultats de l’étude, il a été possible de réaliser un état des lieux précis des outils dont disposent les professionnels des Ehpad. Une présentation de ces résultats sera proposée pour chaque établissement ayant répondu au questionnaire. Un programme d’actions, reprenant les axes à améliorer, sera mis en place dans ces Ehpad. Ceci permettra aux établissements d’intégrer une démarche de qualité dans la prévention du risque infectieux lié à l’HBDP.

We show that these invariants are not enough to determine the Legendrian class of a topologically planar theta-graph. We define the transverse push-off of a Legendrian graph and we determine its self linking number for Legendrian theta-graphs. In the case of topologically planar theta-graphs, we prove that the topological type of the transverse push-off is that of a pretzel link.

description: In der Vergangenheit rückte das Thema eines überhöhten Salzkonsums und damit einhergehend verschiedener chronischer Erkrankungen in den Fokus der Wissenschaft. Enzyme wie Hydrolasen und speziell Peptidasen werden bereits industriell eingesetzt, da sie keine Cofaktoren benötigen, oft bei hohen pH-Werten stabil sind und eine breite Spaltspezifität haben. Eine neue Anwendung von Peptidasen könnte die Generierung von L-Arginyl-dipeptiden sein. Diese Dipeptide haben keinen Eigengeschmack, sind aber in der Lage, den vorhandenen Salzgeschmack zu intensivieren. Um diese Dipeptide zu generieren, sollten in der vorliegenden Arbeit arginylspezifische Peptidasen aus Basidiomyceten isoliert und identifiziert werden. Zunächst wurden verschiedene Peptidasegene aus Trametes versicolor, Phanerochaete chrysosporium und Schizophyllum commune isoliert und in Escherichia coli bzw. Komagataella phaffii exprimiert. Eine Serinpeptidase (ABB73029) aus P. chrysosporium sowie eine Aspartatpeptidase aus T. versicolor (EIW62808) wurden erfolgreich gereinigt. Aktivitätsassays zeigten, dass es sich bei der Aspartatpeptidase nicht um eine arginylspezifische Peptidase handelt, während die Schnittstellenanalyse für die Serinpeptidase aus P. chrysosporium auf eine Exopeptidase hindeutet. In einem zweiten Ansatz wurden 29 Basidiomyceten in Minimalmedium mit 1 % Gluten über einen Zeitraum von 24 Tagen kultiviert und hinsichtlich ihrer Endo- und Exopeptidaseaktivität untersucht. Von den 29 Pilzen wurden insgesamt fünf interessante Spezies mit arginylspezifischer Peptidaseaktivität ausgewählt, darunter Agrocybe aegerita, Fomitopsis pinicola, Flammulina velutipes, Hypholoma sublateritium und Pleurotus eryngii. Nach Reinigung des Kulturüberstandes mittels Größenausschlusschromatographie, wurden aktive Fraktionen mit dem Substrat Casein inkubiert und die Spaltprodukte analysiert. Nur für Peptidasen aus A. aegerita, F. velutipes und P. eryngii wurden Schnittstellen detektiert. Da neben arginylspezifischen Schnittstellen auch ein hoher Anteil unerwünschter Exo-peptidaseschnittstellen ermittelt wurde, handelt es sich bei den Enzymen vermutlich um Exopeptidasen anstatt arginylspezifische Peptidasen. Die Generierung salzgeschmackverstärkender Dipeptide sollte final mit Hilfe einer Dipeptidylpeptidase V (DPPV) aus Pleurotus floridanus erfolgen. PflDPPV wurde heterolog in E. coli produziert und zeigte Optima bei pH 8,5 und 60 °C gegenüber dem Substrat H-L-Ala-L-Ala-para-Nitroanilin. Zudem wurde die Aktivität durch keinen Peptidaseinhibitor vollständig inhibiert.

description: We present a concise review of the recent important experimental developments on neutrino mixing (hints for sterile neutrinos, large $θ_{13}$, possible non maximal $θ_{23}$, approaching sensitivity on $δ_{CP}$) and their implications on models of neutrino mixing. The new data disfavour many models but the surviving ones still span a wide range going from Anarchy (no structure, no symmetry in the lepton sector) to a maximum of symmetry, as for the models based on discrete non-abelian flavour groups that can be improved following the indications from the data.

Novel constructions for the fault-tolerant Toffoli gate

description: We present two new constructions for the Toffoli gate which substantially reduce resource costs in fault-tolerant quantum computing. The first contribution is a Toffoli gate requiring Clifford operations plus only four $T = \exp(iπσ^z/8)$ gates, whereas conventional circuits require seven $T$ gates. An extension of this result is that adding $n$ control inputs to a controlled gate requires $4n$ $T$ gates, whereas the best prior result was $8n$. The second contribution is a quantum circuit for the Toffoli gate which can detect a single $σ^z$ error occurring with probability $p$ in any one of eight $T$ gates required to produce the Toffoli. By post-selecting circuits that did not detect an error, the posterior error probability is suppressed to lowest order from $4p$ (or $7p$, without the first contribution) to $28p^2$ for this enhanced construction. In fault-tolerant quantum computing, this construction can reduce the overhead for producing logical Toffoli gates by an order of magnitude.

description: We explore the detectability of the neutrino flux from the entire Galactic Plane or from a part of it with IceCube. We calculate the normalization and the spectral index of the neutrino power law spectrum from different regions of the Galactic plane, based on the observed spectral characteristics of the pion decay gamma-ray diffuse emission observed by the Fermi/LAT telescope in the energy band above 100 GeV. We compare the neutrino flux calculated in this way with the sensitivity of IceCube for the detection of extended sources. Assuming a binned extended source analysis method, we find that the only possible evidence for neutrino emission for sources located in the Northern hemisphere is from the Cygnus region after 20 years of exposure. For other parts of the Galactic Plane even a 20 years exposure with IceCube is not sufficient for the detection. Taking into account marginal significance of the detectable source in the Cygnus region, we find a precise position and size of the source region which optimizes the signal-to-noise ratio for neutrinos. We also calculate the low-energy threshold above which the neutrino signal could be detected with the highest signal-to-noise ratio. This calculation of precise source position, size and energy range, based on the gamma-ray data, could be used to remove the 'trial factor' in the analysis of the real neutrino data of IceCube. We notice that the diffuse neutrino emission from the inner Galactic Plane in the Southern Hemisphere is much brighter. A neutrino detector with characteristics equivalent to IceCube, but placed at the Northern Hemisphere (such as KM3NeT), would detect several isolated neutrino sources in the Galactic Plane within just 5 years exposure at 5σ level. These isolated sources of ~TeV neutrinos would unambiguously localize sources of cosmic rays which operated over the last 10 thousand years in the Galaxy.[abridged]

description: A skew Calabi-Yau algebra is a generalization of a Calabi-Yau algebra which allows for a non-trivial Nakayama automorphism. We prove three homological identities about the Nakayama automorphism and give several applications. The identities we prove show (i) how the Nakayama automorphism of a smash product algebra A # H is related to the Nakayama automorphisms of a graded skew Calabi-Yau algebra A and a finite-dimensional Hopf algebra H that acts on it; (ii) how the Nakayama automorphism of a graded twist of A is related to the Nakayama automorphism of A; and (iii) that Nakayama automorphism of a skew Calabi-Yau algebra A has trivial homological determinant in case A is noetherian, connected graded, and Koszul.

description: In this paper, we analyze the subspace migration that occurs in limited-view inverse scattering problems. Based on the structure of singular vectors associated with the nonzero singular values of the multi-static response matrix, we establish a relationship between the subspace migration imaging function and Bessel functions of integer order of the first kind. The revealed structure and numerical examples demonstrate why subspace migration is applicable for the imaging of small scatterers in limited-view inverse scattering problems.

description: We report an approach to fully visualize the flow of two immiscible fluids through a model three-dimensional (3D) porous medium at pore-scale resolution. Using confocal microscopy, we directly image the drainage of the medium by the non-wetting oil and subsequent imbibition by the wetting fluid. During imbibition, the wetting fluid pinches off threads of oil in the narrow crevices of the medium, forming disconnected oil ganglia. Some of these ganglia remain trapped within the medium. By resolving the full 3D structure of the trapped ganglia, we show that the typical ganglion size, and the total amount of residual oil, decreases as the capillary number Ca increases; this behavior reflects the competition between the viscous pressure in the wetting fluid and the capillary pressure required to force oil through the pores of the medium. This work thus shows how pore-scale fluid dynamics influence the trapped fluid configurations in multiphase flow through 3D porous media.

description: The two-stream instability has been mooted as an explanation for a range of astrophysical applications from GRBs and pulsar glitches to cosmology. Using the first nonlinear numerical simulations of relativistic multi-species hydrodynamics we show that the onset and initial growth of the instability is very well described by linear perturbation theory. In the later stages the linear and nonlinear description match only qualitatively, and the instability does not saturate even in the nonlinear case by purely ideal hydrodynamic effects.
