Bistable Operation of a Two-Section 1.3-mm InAs Quantum Dot Bistable Operation of a Two-Section 1.3-mm InAs Quantum Dot Laser—Absorption Saturation and the Quantum Confined Stark Laser—Absorption Saturation and the Quantum Confined Stark Effect Effect

— Room temperature, continuous-wave bistability was observed in oxide-confined, two-section, 1.3-m quantum-dot (QD) lasers with an integrated intracavity quantum-dot saturable absorber. The origin of the hysteresis and bistability were shown to be due to the nonlinear saturation of the QD absorption and the electroabsorption induced by the quantum confined Stark effect.
Seasonal Predictability and Spatial Coherence of Rainfall Characteristics in the Tropical Setting of Senegal

This study examines space-time characteristics of seasonal rainfall predictability in a tropical region, by analyzing observed data and model simulations over Senegal. Predictability is analyzed in terms of the spatial coherence of observed interannual variability at the station scale, and within-ensemble coherence of general circulation model (GCM) simulations with observed sea surface temperatures (SSTs) prescribed. Seasonal-mean rainfall anomalies are decomposed in terms of daily rainfall frequency, and daily mean intensity. The observed spatial coherence is computed from a 13-station network of daily rainfall during the July–September season 1961–98, in terms of (a) interannual variability of a standardized anomaly index (i.e. the average of the normalized anomalies of each station), (b) the external variance (i.e. the fraction of common variance amongst stations) and, (c) the number of spatio-temporal degrees of freedom. Spatial coherence of interannual anomalies across stations is found to be much stronger for seasonal rainfall amount and daily occurrence frequency, compared to daily mean intensity of rainfall. Combinatorial analysis of the station observations suggests that, for occurrence and seasonal amount, the empirical number of spatial degrees of freedom is largely insensitive to the number of stations considered, and is between 3 and 4 for Senegal. For daily mean intensity, by contrast, each station is found to convey almost independent information, and the number of degrees of freedom would be expected to increase for a denser network of stations. The GCM estimates of potential predictability and skill associated with the SST forcing are found to be remarkably consistent with 3 those inferred from the observed spatial coherence: there is a moderate-to-strong skill at reproducing the interannual variations of seasonal amounts and rainfall occurrence whereas the skill is weak for the mean intensity of rainfall. Over Senegal during July-September, we conclude that (a) regional-scale seasonal amount and rainfall occurrence frequency are predictable from SST, (b) daily mean intensity of rainfall is spatially incoherent and largely unpredictable at regional scale, and (c) point-score estimates of seasonal rainfall predictability and skill are subject to large sampling variability.
Airbnb purchase intentions: How familiarity and social media Airbnb purchase intentions: How familiarity and social media impacts millennials impacts millennials

Airbnb is one of the most distinguished sharing economy platforms providing guests accommodations. Despite a high number of individuals who use Airbnb, current behavioral intention model, Theory of Planned Behavior (TPB), cannot fully explain guests’ decision-making process to choose such accommodation. Especially, with little to no research being tested on the roles of social media influences and familiarity as information sources associated with the TPB model. The objective of this study is to examine the intentions of millennials to use Airbnb and to investigate TPB model with social media influences and familiarity as mediators on purchasing intentions. Through convenience sampling, a survey of 123 millennials were gathered and analyzed for this study. By employing ANOVA and Baron and Kenny’s Method for Mediation, this study found that both social media influences and familiarity have a mediating effect on the TPB model, and familiarity also playing a partial mediating role in the relationship between social media influence and behavioral intention. This study extends the application of the TPB model and is valuable for Airbnb and Airbnb hosts to understand the intention segments to better comprehend and develop effective marketing strategies towards consumers.
RISK ASSESSMENT OF CONTROL AND DECISION-MAKING IN THE AIRCRAFT CONTROL SYSTEM

The aim of the article is to develop a methodology for quantitative assessment of the risks of control and decision-making in the control system of complex objects using the example of aircraft. Manned and unmanned vehicles are considered as aircraft. The risk is presented in the work as a complex multifactorial qualitative phenomenon of a stochastic nature. For quantitative risk assessment, formal mathematical and simulation models are proposed. The process of control and decision making is studied as a complex stochastic-programmable system in the conditions of digital transformation of the internal and external environment. Under the external environment, the aviation industry is represented, and under the internal environment, the aviation enterprise. The quantitative level of control risks, conceptually and in practice, is proposed to be assessed by the digital maturity of the stages of the life cycle of control agents: design, production, and operation. The general approach and tasks of studying the processes of risk formation in the management of aircraft are presented systematically in three digital conceptual contexts. In the volume of the general context, the concept of the digital transformation of the aviation industry is explored. At the second conceptual level, the problem is considered on the example of an aviation enterprise. At the third system level, the most dynamically developing digital technologies in practice, such as "Maintenance of aviation equipment" and "Components of robotics and sensors" are explored. The unmanned aerial vehicle is presented as a robotic complex. In these structural and functional technologies of digital transformation, the most promising and significant digital components are "Staff "; "Models"; "Infrastructure and tools"; "Processes and Products"; "Data". The least secure system link in the exchange of information between an aircraft and the external environment is a radio channel, which is proposed to be replaced by VLC technology in the face of external cyber threats. The formalization of the process of quantitative assessment of the level of digital maturity of an aviation enterprise and the practiced control system in the study is based on a multi-approach methodology using sections of probability theory, mathematical statistics, simulation modeling, and the method of expert assessments.
Sedimentological impact of artificial islands and pits, measured with sediment traps

Sediment traps have been applied in the Oresund Sound in order to investigate the possible sedimentological effect of the construction of a fixed link between Denmark and Sweden during the period 1995-2000. Results from measurements made around test islands and test pits carried out during March 1993 are presented. It was impossible to separate the sedimentological impact of the test islands from the background sedimentation during both calm and windy periods due to its small magnitude compared to the natural sediment transport. The sedimentation in two test pits was measured with sediment traps and compared favourably with observations of sedimentation on the pit bottoms, indicating that the traps give a good measure of how fast a tunnel trench, pits for bridge piers and pylons, etc. are refilled with sediments after excavation.

BIG DATA ANALYTICS FOR PREDICTION USING SENTIMENT ANALYSIS APPROACH

Extraction of public opinion is a way of gathering knowledge based on short texts written by users to provide attitudes. This condition encourages a lot of research using social media, especially the sentiment analysis approach in conducting initial identification or predictions. Social media is a dynamic medium to get public opinion which is very cheap and very large in number. This research aims to provide a review of predictions using sentiment analysis, one of the analytical methods in big data analytics. Sentiment analysis techniques are used to predict customer review, market, health, and social behavior. The sentiment analysis approach sourced from social media is able to contribute to making predictions in the form of an early warning system of problems so that it can help decision-makers based on big data analytics.
APPLYING SERIOUS GAME ELEMENTS TO ENHANCE FLOOD SAFETY TRAINING MANAGEMENT

One of the critical elements of catastrophe preparedness could be a training of the disaster responders and a society. However, conducting live disaster training is expensive and la-bor-intensive. Hence, a serious game (SG) may offer a possible solution as a technique of disaster and safety education. Training is one of the areas where by serious games must have a combination of elements may lead to the productive development of serious games. There are serious games that have been developed; however, there is a lack of elements in the game fewer use elements of scenario and feedback. Therefore, this work gamifies the topic of flood safety management an element of predictability that can be utilized as a gaming element involving time limits to reduce the amount of flood destruction and loss of life. This paper aims to describe a process to evaluate the model of a serious game for flood safety training based on the gaming elements using the Inter-Rater Reliability (IRR) method. The overall result of IRR percentage has gained 93% compared to the existing works and has proven. The hypothesis that serious games have a positive impact as a pedagogic tool on the educational and training process.
Quantifying daily rhythms with non-negative matrix factorization applied to mobile phone data

Human activities follow daily, weekly, and seasonal rhythms. The emergence of these rhythms is related to physiology and natural cycles as well as social constructs. The human body and its biological functions undergo near 24‑h rhythms (circadian rhythms). While their frequencies are similar across people, their phases differ. In the chronobiology literature, people are categorized into morning‑ type, evening‑type, and intermediate‑type groups called chronotypes based on their tendency to sleep at different times of day. Typically, this typology builds on carefully designed questionnaires or manually crafted features of time series data on people’s activity. Here, we introduce a method where time‑stamped data from smartphones are decomposed into components using non‑negative matrix factorization. The method does not require any predetermined assumptions about the typical times of sleep or activity: the results are fully context‑dependent and determined by the most prominent features of the activity data. We demonstrate our method by applying it to a dataset of mobile phone screen usage logs of 400 university students, collected over a year. We find four emergent temporal components: morning activity, night activity, evening activity and activity at noon. Individual behavior can be reduced to weights on these four components. We do not observe any clear categories of people based on the weights, but individuals are rather placed on a continuous spectrum according to the timings of their phone activities. High weights for the morning and night components strongly correlate with sleep and wake‑up times. Our work points towards a data‑driven way of characterizing people based on their full daily and weekly rhythms of activity and behavior, instead of only focusing on the timing of their sleeping periods. Our lives are defined by rhythms of different frequencies: daily, weekly, seasonal, and annual, among others. The most
Mycobacterium tuberculosis senses host Interferon-γ via the membrane protein MmpL10

Mycobacterium tuberculosis (Mtb) is one of the most successful human pathogens and remains a leading cause of death from infectious disease. Interferon-γ (IFN-γ) is a central regulator of the immune defense against Mtb. Several cytokines have been shown to increase virulence of other bacterial pathogens, leading us to investigate whether IFN-γ has a direct effect on Mtb. We found that both recombinant and T-cell derived IFN-γ rapidly induced a dose-dependent increase in the oxygen consumption rate (OCR) of Mtb, consistent with increased bacterial respiration. This was also observed in clinical strains, but not in the vaccine strain Bacillus Calmette–Guérin (BCG), and did not occur for other cytokines tested, including TNF-α. IFN-γ binds to the cell surface of intact Mtb, but not BCG, whilst TNF-α binds to neither. Mass spectrometry analysis identified mycobacterial membrane protein large 10 (MmpL10) as the transmembrane binding partner. Consistent with this, IFN-γ binding and the OCR response was absent in a Mtb Δmmpl10 strain and restored by complementation of the mutant strain. RNA-sequencing of IFN-γ exposed Mtb revealed a distinct transcriptional profile, including genes involved in virulence and cholesterol catabolism. Finally, exposure of Mtb cells to IFN-γ resulted in sterilization of bacilli treated with isoniazid (INH), indicating clearance of phenotypically resistant bacteria that persist in the presence of INH alone. Our data suggest a novel mechanism allowing Mtb to respond to host immune activation that may be important in the immunopathogenesis of TB and have use in novel eradication strategies. One-Sentence Summary IFN-γ is a critical component of effective immune defense in human tuberculosis yet its causative agent, Mycobacterium tuberculosis it able to sense this cytokine and increase virulence and respiration in response.
Revisiting trends of morphology of antennal sensilla in Scarabaeoid beetles

Phytophagous scarab beetles associated with Angiosperms have characteristically enlarged lamellate antennae and exhibit a striking morphological variation of sensilla. In this study, we compared the morphology of antennal surface of 62 species Scarabaeoidea using SEM microscopy, particularly also in light of their evolution in association with Angiosperms. We investigated the correlation of antennal sensilla morphology, i.e., their structure and distribution, with species diversity and lineage diversi�cation rates. A high diversity of sensilla was observed but also multiple transitional forms, even on the same antennomere. We interpreted this as evidence for a high evolutionary plasticity. We recognized clear patterns of convergence and repeated evolution of certain types of placoid sensilla. One main tendency found in the phytophagous Pleurostict chafers was a shift from sensilla trichodea to placoid-like sensilla, apparently also enhanced by the increase of the lamellate antennal surface, either by size or number of the lamellae. This trend occurred not only in the Pleurosticts, but also in Glaphyridae, a second Angiosperm-associated lineage of Scarabaeoidea. However, our results suggest no direct relation between species diversity or the rate of diversi�cation and general sensilla morphology, i.e., the origin of placoid sensilla. This could be explained by species-poor lineages also possessing placoid sensilla but also by otherwise successful and species rich groups having sensilla trichodea (e.g., dung beetles). Results further reveal the need to re�ne current phylogenetic hypotheses by more comprehensive taxon sampling and to expand the molecular characterization of pheromones and odor binding proteins to better understand the role of chemical communication in scarab diversi�cation.
Active tectonics of the Adriatic Region

Seismicity and fault-plane solutions show that the active deformation in the Adriatic region is very varied. West of Messina, N–S shortening occurs with slip vectors representative of the overall Africa–Eurasia motion. Along the length of peninsular Italy, NE–SW extension on normal faults is the dominant style of deformation, but changes to N–S shortening in N. Italy. Inland central and northern Yugoslavia is deforming on strike-slip and thrust faults, and an intense belt of NE–SW shortening continues south along the coast from central Yugoslavia into Albania. South of Albania the shortening in coastal regions is in a more easterly direction. The most remarkable feature of the region is the low level of seismicity in the Adriatic Sea itself, compared with the intense activity in the high topographic belts that border it on the SW, NW and NE. The relatively rigid behaviour of the Adriatic allows its motion relative to Eurasia to be described by rotation about a pole in N. Italy. Anticlockwise rotation about this pole accounts, in a general way, for the change in style and orientation of the deformation in the circum-Adriatic belts. Historical and recent seismicity account for approximately equal rates of extension in central Italy and shortening in southern Yugoslavia of about 2 mm yr−1; however, these are uncertain by at least a factor of two, and are anyway likely to be underestimates of the true motion, because of the unknown contribution of aseismic creep. The Adriatic region resembles, in some ways, other relatively stable continental blocks, such as Central Iran and the Tarim Basin, that are caught up within the distributed deformation of the Alpine–Himalayan Belt. The Adriatic, however, is bounded on three sides by the relatively stable Eurasia plate. Its boundary with the African plate is short and ill-defined by seismicity, but is likely to be located in the Southern Adriatic, near the Strait of Otranto. The present day seismicity shows that the Adriatic, although once perhaps ‘a promontory of Africa', is no longer behaving in this way, and the motions on its boundaries do not directly reflect the Africa–Eurasia convergence.
Data-driven subtypes of major depressive disorder

The frequent occurrence of comorbidity has brought about an extensive theoretical debate in psychiatry. Why are the rates of psychiatric comorbidity so high and what are its implications for the ontological and epistemological status of comorbid psychiatric diseases? Current explanations focus either on classification choices, or on causal ties between disorders. Based on empirical and philosophical arguments, we propose a conventionalist interpretation of psychiatric comorbidity instead. We argue that a conventionalist approach fits well with research and clinical practice and resolves two problems for psychiatric diseases: experimenter’s regress and arbitrariness.
Distribution of picophytoplankton and bacterioplankton along a river plume gradient in the Mediterranean Sea

Le Rhone est un fleuve important qui se deverse dans les eaux pauvres en nutriments de la Mediterranee induisant la formation de gradients chimiques et physiques. La distribution du picophytoplancton et du bacterioplancton dans le panache du Rhone a ete etudiee en novembre 1998, et en mars et avril 1999. Les abondances de trois groupes de picophytoplancton (Prochlorococcus [PRO], Synechoccocus [SYN], petites cellules eucaryotes [PEUK]) et deux groupes de bacteries differant par leur contenu en acides nucleiques furent determinees par cytometrie en flux. PRO etaient abondants en novembre dans le panache fluvial (7-23 x 10 3 cells.ml -1 ) mais ne furent pas detectes en mars et avril. Les abondances de SYN (3-20 x 10 3 cells.ml -1 ) et de PEUK (0.5-4 x 10 3 cells.ml -1 ) etaient similaires en novembre et mars. En avril, les concentrations de chlorophylle a (Chl a) etaient maximales (> 15 μg.L -1 ) aux salinites intermediaires (de 30 a 35). A cette periode, la distribution des PEUK suivait celle des concentrations en Chl a, tandis que les abondances de SYN etaient negativement correlees aux concentrations de Chl a. Les abondances et la production bacteriennes etaient fortement correlees aux concentrations de Chl a en avril, alors que seule la production bacterienne l'etait en mars. En avril, l'abondance des bacteries avec un fort contenu en acides nucleiques (HNA) etait mieux correlee avec la production bacterienne et les concentrations en Chl a que ne l'etaient les bacteries avec un faible contenu en acides nucleiques (LNA). Ceci suggere que les bacteries HNA etaient la fraction la plus active de la communaute bacterienne.
Effect of melatonin implants on the dry period of dairy goats

The dry period in a dairy animal appears to be essential for ensuring milk yield in the subsequent lactation. Subclinical udder infections may appear in this period (Contreras and Rodriguez 2011). Inflammations of the mammary gland are recognized as a situation of oxidation stress. Melatonin improves the activity of antioxidant enzymes and it might help to control free radical excess (Yawno et al . 2013). The aim of this work is to check the effect of the administration of melatonin in the antioxidant status of dairy goats in the dry period. Verata does of same body condition, age (3 to 5 years), parity (2 to
Updated and broader

This study investigates a question relevant to many investors: do the broad Real Estate Investment Trust (REIT) return characteristics reflect those of the broad direct real estate markets. The paper makes several contributions to the literature in addition to using more recent data: (1) we use data for six countries (Australia, France, Germany, Netherlands, the U.K., and the U.S.); (2) we estimate both country-specific and panel models to increase the reliability and generalizability of the analysis; (3) we estimate a structural vector autoregressive model to be able to better and more reliably interpret the various shocks in the system; and (4) we investigate the effects of global liquidity shocks, among other shocks. Our results indicate that over the mid to long horizon, broad REIT and direct returns have similar characteristics and are highly correlated at the panel level. Also, the two types of exposure to real estate exhibit similar reactions to economic shocks. Thus, the paper makes a case that investors do not necessarily need to worry much about compositional effects when aiming to track broad international direct market performance by investing in listed real estate.
