High signal-to-noise ratio for high-impedance-loaded nano-photodetector toward attojoule optical reception
Authors: Nozaki Kengo , Matsuo Shinji , Fujii Takuro , Takeda Koji , Shinya Akihiko , Notomi Masaya
Published: December 2019

We demonstrate a high signal-to-noise ratio (SNR) for a photonic-crystal nanophotodetector (PD). The ultralow-capacitance nano-PD can be terminated with a load resistor with a resistance as high as 59 kΩ for efficient light-to-voltage conversion, and its strong thermal-noise suppression leads to an SNR that is 30 dB higher than that of the conventional p-i-n PD terminated with a 50-Ω load. The noise equivalent power is only 500 fW/√Hz, while a gigahertz-level bandwidth can be maintained when considering that the PD capacitance is only 1 fF. Theoretically, this allows optical reception at less than 100 aJ to obtain a bit error rate of 10–9. The resistor-loaded nano-PD requires a small electrical biasing energy comparable to the optical energy, which is remarkably energy saving compared with avalanche PDs or other PDs integrated with amplifiers. Such a receiver promises a dense optical interface with CMOS electronics in photonic networking and processing chips.

Published: December 2019

Due to their biological importance, the photochemistry of blue-light photoreceptor proteins has been studied extensively over the last few decades. Most blue-light photoreceptors, such as cryptochromes and phototropins, utilize flavin chromophores as their cofactors. After irradiation with light, the chromophore undergoes electron transfer with nearby redox-active amino-acid residues within the protein, whereby this first step of signal transduction may be initiated either from the flavin’s excited singlet or triplet state. Despite the collective effort of theoreticians and experimentalists to characterize and understand the photochemistry of flavoproteins, the mechanistic details of the excited state processes initiating signal transduction are yet to be revealed. Here, we use a light-oxygen-voltage-sensing domain from Avena sativa phototropin to get additional insight into the excited state photochemistry of flavoproteins. The influence of structural variations of the cofactor flavin mononucleotide (FMN) is explored by varying the methyl substitution pattern in positions 7 and 8 of the flavin core. The photophysical properties of the FMN derivatives, in the absence and presence of the protein environment, are investigated by UV-vis absorption, fluorescence, and electron paramagnetic resonance spectroscopies as well as cyclic voltammetry. The comparison of the properties of the modified flavin cofactors with those of FMN shows that the rates of the different excited state reactions, and therefore also the singlet/triplet yields, can be modulated substantially by only minor structural modifications of the flavin core.
Vibrational (resonance) Raman optical activity with real time time dependent density functional theory
Authors: Mattiat Johann , Luber Sandra
Published: December 2019

We present a novel approach for the calculation of vibrational (resonance) Raman optical activity (ROA) spectra based on real time propagation. The ROA linear electronic response tensors are formulated in a propagator formalism in order to treat linear response (LR-) and real time time dependent density functional theory (RT-TDDFT) on equal footing. The length, mixed, and velocity representations of these tensors are discussed with respect to the potential origin dependence of the ROA invariants in the calculations. The propagator formalism allows a straight forward extension of the optical LR tensors in a mixed or velocity representation to a coupling with nonlocal potentials, where an extra term appears in the definition of the momentum operator, in order to maintain the gauge invariance. Using RT-TDDFT paves the way for an innovative, efficient calculation of both on- and off-resonance ROA spectra. Exemplary results are given for the off-resonance and (pre-)resonance spectra of (R)-methyloxirane, considering the resonance effects due to one or more electronically excited states. Moreover, the developed real time propagation approach allows us to obtain entire excitation profiles in a computationally efficient way.
γ-GeSe: A two-dimensional ferroelectric material with doping-induced ferromagnetism
Authors: Liu Chang , Guan Shan , Yin Huabing , Wan Wenhui , Wang Yuanxu , Zhang Ying
Published: December 2019

Two-dimensional (2D) ferroelectricity and ferromagnetism have attracted a lot of attention due to their promising applications, but 2D materials with both properties are quite rare. Here, by performing first-principles calculations, we propose that monolayer γ-GeSe is a 2D ferroelectric material with an out-of-plane polarization of about 6.48 × 10−12 C/m. It has a Mexican-hat-like band structure, leading to itinerant ferromagnetism upon hole doping. This ferromagnetic phase transition occurs when the doping concentration is about 7.4 × 1012/cm2, and the ferromagnetism can be maintained near 880 K when increasing the doping concentration. Both the ferroelectricity and the induced ferromagnetism can be well modulated by strain. These features make γ-GeSe a promising material for making microelectronics and spintronics devices. Our work also paves the way for searching long-sought high temperature 2D multiferroics.
Hydrogen gas ppb-level detection based on AlGaN/GaN high electron mobility transistor with 2.0 nm thick Pt gate layer

Published: December 2019

In this work, ppb-level H2 gas detection based on the Pt-gated AlGaN/GaN high electron mobility transistor device was obtained through minimizing the H atom diffusion distance by the utilization of a critical Pt gate thickness of ∼2.0 nm. The Ids-Vds curves show that the device exhibits a pinch-off characteristic with an on-to-off ratio of about four orders of magnitude. High response (775% at 100 ppm, 25.4% at 1 ppm) and short response times (2.5 s at 10 000 ppm) are observed at 150 °C. Particularly, the device has a response to trace H2 gas as low as 60 ppb, indicating a small low limit of detection (LOD) < 60 ppb. Its capability to detect very low H2 gas together with a high response makes it promising for trace H2 gas detection such as exhale breath analysis. Moreover, it is found that the H2 detection range depends on the operating temperature, which is useful in real applications that require various H2 gas detection ranges.
Generation of surrogate event sequences via joint distribution of successive inter-event intervals
Authors: Ricci Leonardo , Castelluzzo Michele , Minati Ludovico , Perinelli Alessio
Published: December 2019

The study of many dynamical systems relies on the analysis of experimentally-recorded sequences of events for which information is encoded in the sequence of interevent intervals. A correct interpretation of the results of the application of analytical techniques to these sequences requires the assessment of statistical significance. In most cases, the corresponding null-hypothesis distribution is unknown, thus forbidding an evaluation of the significance. An alternative solution, which is efficient in the case of continuous signals, is provided by the generation of surrogate data that share statistical and spectral properties with the original dataset. However, in the case of event sequences, the available algorithms for the generation of surrogate data can become cumbersome and computationally demanding. In this work, we present a new method for the generation of surrogate event sequences that relies on the joint distribution of successive interevent intervals. Our method, which was tested on both synthetic and experimental sequences, performs equally well or even better than conventional methods in terms of interevent interval distribution and autocorrelation while abating the computational time by at least one order of magnitude.

Farm injury resulting in hospital admission: a review of farm work and non-farm work-related injury
Authors: Amey Janet , Christey Grant
Published: December 2019

ABSTRACT INTRODUCTIONOccupational health on farms is important because farms are not only workplaces where agriculture workers are vulnerable to high injury and fatality rates, they are also homes where families and visitors undertake a variety of activities that can result in injury. AIMTo profile and describe injuries requiring hospital admission that occurred on farms, both for injuries related to farming activities and injuries unrelated to farm work in the Midland region of New Zealand. METHODSA review of anonymised prospectively collected Midland trauma registry data from 1 July 2012 to 30 June 2018 was undertaken. Cases include unintentional injuries occurring on a farm. Non-major injuries are included to better quantify the trauma burden. RESULTSIn total, 2303 hospital admissions met the study criteria. Non-major injury accounted for 93.1% of events and 45.0% of injuries occurred during farming activities. Five people died in hospital; all injured while undertaking farm work. Males made up 84.8% of farm work and 70.9% of non-farm work injuries. Horse riding had the highest number of injuries, with off-road motorcycles, livestock, falls and quad bike injuries comprising the most common injury activities and mechanisms. Farming-related major injuries commonly involved quad bikes, non-traffic vehicles and motorcycles. Farmers in the Districts of Waitomo, Rotorua, Waipa and Taupō had the highest standardised hospitalisation rates. DISCUSSIONThe nature of farms and farming exposes people to different risks from the risks people in urban areas are exposed to. Injury prevention efforts should remain on work-related farming injuries, but also encompass the high number of injuries that are not related to farm work but happening on farms.

Abstract
ContextUnderstanding the factors that determine the distribution and abundance of species is an important aim of ecology and prerequisite for conservation. The Andean cat (Leopardus jacobita) and the pampas cat (L. colocolo) are two of the least studied felids. Both are threatened, of similar size and live sympatrically in the Andes of Argentina, Bolivia, Chile, and Perú.
AimsWe aimed at estimating the population densities of the Andean cat and pampas cat in two continuous areas and to analyse the activity patterns of these two species and that of mountain vizcacha (Lagidium viscacia), the main prey of the Andean cat.
MethodsWe used camera traps to evaluate the density of both felid species using the space explicit capture recapture (SECR) framework and the overlap in their activity patterns with that of mountain vizcacha, using the kernel-density estimator in two contiguous areas in the Bolivian Altiplano, at Muro-Amaya and at Micani, both within the Ciudad de Piedra region.
Key resultsAndean cat density was estimated at 6.45 individuals per 100km2 in Muro-Amaya and 6.91 individuals per 100km2 in Micani, whereas the density of the pampas cat was 5.31 individuals per 100km2 and 8.99 individuals per 100km2 respectively. The Andean cat was mainly nocturnal, whereas the pampas cat was cathemeral. The activity of the mountain vizcacha overlapped less with that of its specialised predator, the Andean cat, than with that of the pampas cat.
ConclusionsIn line with our predictions, the Andean cat, considered a more specialised nocturnal hunter, particularly of mountain vizcacha, had lower population densities than did the more generalist pampas cat.
ImplicationsLow population densities, as compared with theoretical expectations, pose an additional conservation problem for these felids, in an area such as the high Andes.
L’équivalence dynamique dans la traduction française des romans de Fagunwa
Authors: Adegboye Gbadegesin Olusegun
Published: December 2019

La traduction de la littérature fait l’objet de nombreux débats depuis plusieurs décennies et, sur la base de ces
débats, des approches ont été formulées en fonction des points de vue des précurseurs en ce qui concerne les défis de leur tâche.
L’auteur d’une œuvre littéraire est influencé par son expérience de la vie, sa culture, son imagination, sa société, l’idéologie
de son peuple, etc. Une œuvre littéraire, fortement imprégnée de nuances culturelles, est toujours en opposition avec la langue du
récepteur. Les romans yorubas de Daniel Olorunfemi Fagunwa en sont un bon exemple. Pour amener le lecteur de la version française
à réagir au message du texte original de manière identique ou pratiquement identique, Olaoye Abioye, le traducteur de ces romans,
confère une valeur secondaire au style de Fagunwa. Par cette approche, l’équivalence dynamique, une idée avancée par le traducteur
de la bible, Eugene Nida, est inconsciemment mise en jeu. La compréhension du lecteur récepteur lui est imposée dans le cadre de
son contexte culturel pour éviter toute trahison ou contre-sens dans les versions françaises. Dans cet article, nous abordons la
dichotomie entre l’imposition et la trahison en traduction, l’imposition et la trahison dans l’optique de l’équivalence dynamique
et l’imposition ou la trahison dans la traduction française de deux romans de Fagunwa. Il conclut que l’imposition est une
exigence en traduction littéraire.
“By the elders’ leave, I do”
Authors: Koutlaki Sofia A
Published: December 2019

The basis of this study is the view that social ritual practices embody and reinforce the moral order of
communities. It takes a step towards providing more empirical research on the ritual practices in lesser studied languages by
examining ethnographic data collected during marriage ceremonies in Tehran. Extracts taken from marriage ceremonies and a film
extract are examined in terms of recurrence, liminality, embodiment of the moral order and
emotivity, elements identified in Kádár’s definition of ritual (2017). The paper makes a theoretical contribution by showing that ostensivity can also be considered
an important facet of ritual. In ritual practices connected with marriage, ostensivity is experienced by participants and
observers as a means of maintaining the moral order. The paper proposes future areas of research for the theoretical refinement of
the concept of ostensivity and further examination of the relationship that ostensivity has with ta’arof (Iranian
ritual politeness) and face.

This briefing aims to: (1) summarise the poverty debate and (2) explain differences between the estimates produced by different authors. The key points are that: (1) there has been a sharp increase in poverty since 2011 according to all consistent trend estimates; (2) the finding is robust to all reasonable assumptions about inflation and price data; and (3) the National Institute of Statistics of Rwanda’s findings do not tally with their own stated assumptions about inflation.
Large-alphabet quantum key distribution using spatially encoded light
Authors: Tentrup T B H , Luiten W M , Meer R van der , Hooijschuur P , Pinkse P W H
Published: December 2019

Most quantum key distribution protocols using a two-dimensional basis, such as HV polarization as first proposed by Bennett and Brassard in 1984, are limited to a key generation density of 1 bit per photon. We increase this key density by encoding information in the transverse spatial displacement of the used photons. Employing this higher-dimensional Hilbert space together with modern single-photon-detecting cameras, we demonstrate a proof-of-principle large-alphabet quantum key distribution experiment with 1024 symbols and a shared information between sender and receiver of 7 bit per photon.
Fostering collective action to reduce wildfire risk across property boundaries in the American West
Authors: Charnley Susan , Kelly Erin C , Fischer A Paige
Published: December 2019

Large-scale, high-severity wildfires are a major challenge to the future social-ecological sustainability of fire-adapted forest ecosystems in the American West. Managing forests to mitigate this risk is a collective action problem requiring landowners and stakeholders within multi-ownership landscapes to plan and implement coordinated restoration treatments. Our research question is: how can we promote collective action to reduce wildfire risk and restore fire-resilient forests in the American West? To address this question we draw on collective action theory to produce an environmental public good (fire-resilient forests), and empirical examples of collective action from six projects that are part of the US Forest Service–Natural Resources Conservation Service Joint Chiefs’ Landscape Restoration Partnership. Our findings are based on qualitative, semi-structured interviews conducted with 104 individuals who were purposively selected to represent the diverse stakeholders involved in these projects. Fostering collective action to restore fire-resilient forests entails getting as many landowners (especially large landowners) to participate in wildfire risk reduction as possible to increase its areal extent; and landowner coordination in planning and implementing strategically-designed restoration treatments to optimize their effectiveness. We identify factors that enabled and constrained landowner participation and coordination in the Joint Chiefs’ projects. Based on our findings and theory about when collective action will emerge, we specify a suite of practices to promote collective action for wildfire risk reduction across property boundaries, emphasizing incentives and enabling conditions. These include proactive education and outreach targeting landowners; multi-stakeholder processes with broad landowner representation to develop coordinated management approaches; financial and technical assistance to support fuels treatments on all ownerships within similar time frames; strong partnerships; and using common forestry professionals to plan and implement treatments on different ownerships (especially private lands). Our findings can inform cross-boundary management for landscape-scale conservation and restoration in other contexts.

Future changes in climate and socioeconomic systems will drive both the availability and use of water resources, leading to evolutions in scarcity. The contributions of both systems can be quantified individually to understand the impacts around the world, but also combined to explore how the coevolution of energy-water-land systems affects not only the driver behind water scarcity changes, but how human and climate systems interact in tandem to alter water scarcity. Here we investigate the relative contributions of climate and socioeconomic systems on water scarcity under the Shared Socioeconomic Pathways-Representative Concentration Pathways framework. While human systems dominate changes in water scarcity independent of socioeconomic or climate future, the sign of these changes depend particularly on the socioeconomic scenario. Under specific socioeconomic futures, human-driven water scarcity reductions occur in up to 44% of the global land area by the end of the century.

Knowledge management develops as an important and strategic part in managing HR in educational institutions. The rapid changes in all fields of life, due to the effects of globalization and the development of highly accelerated information technology. This condition clearly results in the need for new ways of addressing everything that happens to survive. The emphasis on the increasing importance of the quality of human resources (HR) is one of the responses in addressing these changes. In this connection the role of science becomes more prominent, because only with knowledge all changes that occur can be addressed appropriately. This means that education plays an important role in preparing quality and competitive human resources. Recognizing increasingly severe competition, it is necessary to change the cultural paradigm from the one originally relied on resouce-based to knowledge-based which relies on the analysis of the field of science. To be able to manage their knowledge management well. Then an organization must be able to understand the history of the development of knowledge management culture with both individuals, groups or organizations must be able to survive in an era full of uncertainty (chaos and complexcity). Learning organizations that contain individual learners who are supported by a strong infrastructure ranging from procurement of information to structured knowledge in a digital library, are then socialized to produce new values in the organization. Where new values change the perspective of each element of the organization to develop in a better direction.

Biological test of the laundry industry toxicity of detergents and concentration of hemoglobin in tilapia (oreochromis niloticus
Authors: Saparuddin  , Arbain
Published: December 2019

The detergent from the laundry industry that continues to flow directly into the river will affect the oxygen supply of the aquatic biota, due to the disruption of the respiratory system. The objective is to determine the level of toxicity and hemoglobin concentration of tilapia (Oreochromis. niloticus) exposed to detergent residues from the laundry industry. This research method uses a randomized block design. This test was performed with five treatments and control with three repetitions. Each treatment was filled with detergent residues from the laundry industry with varying levels of concentration, namely 0%, 1%, 2%, 3%, 4% and 5% in each aquarium. The results showed that the highest mortality of tilapia occurred at a concentration of 5% up to 8 tails. While the lowest concentration of hemoglobin on day 10 and day 20 each occurred at a concentration level of 4% in (8.37% gr and 7.65% gr), while on day 30, the lowest concentration of hemoglobin was found in the Treatment concentration level of 5% for (6.42 gr%). It can be concluded that residues from the washing industry can affect the oxygen supply in fish, which is characterized by a reduced concentration of hemoglobin in tilapia from the normal concentration of hemoglobin.

Authors: Polishchuk A I , Semenov I V , Maksimov F A
Published: December 2019

Method of final setting calculation for a single injection hanging pile 3 to 5 m length in clay soils is proposed. The method is based on the separate work of the lower end and the lateral surface of the injection pile; it takes into account the linear and non-linear dependencies of its setting from external load. The method takes into account the stages of the well formation by the injector pressing, its radial expansion during the concrete injection, and the physical and mechanical characteristics improvement of the soil around the injection pile barrel at its construction stage. The obtained results are considered as an approach to solving a complex task of estimating the deformations of individual and strip foundations after their strengthening with injection piles under buildings reconstruction. It can be used to predict the buildings foundations setting under new construction.

The unbalanced gyroscope stability investigation
Authors: Titova T N
Published: December 2019

In this paper the stability of motion of an unbalanced gyroscope with a flexible shaft in gimbal suspension is considered. First, we consider linear Hamiltonian systems of differential equations. A solution stability criterion is obtained in one case. Next, we explore the gyroscope motion. It consists of an internal and external framework. In the normal position, the axes of the frames and the rotor are mutually perpendicular and intersect at a point that is a fixed point of suspension. Friction in the bearings of the rotor and the frame is missing. The rotor motion system equations and gyroscope frames are considered in the first approximation. The case is considered when the characteristic equation corresponding to the motion equations in the first approximation has eigenvalues with a zero-real part. The stability criterion is obtained.

Published: December 2019

In modern conditions, one of the ways allowing the construction company to be competitive in the market is the use of modern high – quality and, at the same time, cheaper building materials. Many technogenic formations, in particular solid waste are valuable technological raw materials and can be involved in technological redistribution in order to obtain composite building materials. In the production of crushed stone, sands from lithoid pumice and perlite, it is advisable to produce separation and separate obsidian. In this case, the separated obsidian turns into production waste. The expantion of obsidian will allow to obtain a large porous ultralight material and thereby solve environmental issues – recycle production waste. On the base of expanded obsidian, it is possible to obtain new types of effective composite thermal insulation and acoustic materials (cellular concretes and acoustic plasters), which have high performance properties and expand the range of effective building composite materials.

Lighting design is the area regulated today only indirectly, proceeding from requirements of visibility of objects, mainly, criteria of quantity of light on road coverings and facades of the lit objects and uneven distribution on them. There is an underestimation of its role and potential in creating an artistic image of the city in the design of its architectural environment, counting on the visual perception of it only in the daytime. Purpose of research. To identify and formulate problems and prospects for the development of lighting design, to develop recommendations for the light solution of the urban environment. To consider the light environment as a system, to determine the main levels of architectural and compositional tasks of its formation. Method of research. With the help of the analysis of the light environment of the city of Belgorod the problems of its formation are revealed. The main disadvantage of the formation of the urban light environment is the lack of unity in the solution of lighting different areas of the city, the prevalence of light advertising over architectural objects, destroying the stylistic unity of the urban environment. The comparison of the solution of such problems by the Metropolitan administration is carried out. The importance of light as a factor in the formation of the originality of the city is noted. Research result. The development of the concept of urban lighting is proposed, its basic principles are highlighted, ways of solving the problem of organizing night lighting of the urban environment are identified. The potential of lighting design and lighting technologies in modern architecture is only half, and in Russian projects – hardly a quarter. We are in the beginning, but a growing number of interesting projects gives reason to believe that we are moving in the right direction and with the right approach, using the expertise already available, by purchasing and accumulating your own will inevitably achieve the development of their professional achievements in the field of lighting design and the organization of the light environment of the city. Currently, the problem of competent and qualified approach to urban lighting requires the full attention of architects-urban planners and architectural and design organizations.

One of the state environmental policy priorities both in Russia and other countries is the preservation and development of nature reserves and specially protected natural territories. The article discusses the state natural reserve “Belogorye” Belgorod region. The nature reserve “Belogorye” territory includes five sites in different municipal districts of the region. The main problem of the reserve development is that its territory is of an island character, does not have connecting elements and is a subject to human impact. To solve the specially protected and adjacent territories development existing problems, a conflict approach, which consists of identifying the subjective and objective territorial development contradictions, identifying urban the planning activities participants (subjects) personal conflicts and finding the means and possibilities to resolve these conflicts by legal and urban planning methods, is proposed. The analysis of the the most problematic areas limitations and burdens of the Belogorie reserve is made. Identified and classified urban conflicts in relation to the reserve territory among which are: land use, social and functional purposes, transport, regulatory documents, property. The regional significance cultural heritage objects are revealed - architectural monuments and historically significant places (zaseki). A territories adjacent functioning model to the reserve has been developed. It also proposes the cultural heritage object reconstruction with the hotel and a museum adaptation.
