2 A Gravity Dual of Momentum Relaxation with Electric Field

We studied the holographic entanglement entropy for a strip and sharp wedge entangling regions in momentum relaxation systems. In the case of strips, we found analytic and numerical results for the entanglement entropy and showed the effect on the minimal surface by the electric field. We also studied the entanglement entropy of wedges and confirmed that there is a linear change in the electric field. This change is proportional to the thermoelectric conductivity, ᾱ, that can be measured. ∗e-mail : kimkyungkiu@sejong.ac. kr †e-mail : cyong21@gist.ac. kr ‡e-mail : junghun.lee@gist.ac. kr §e-mail : bjahn@yonsei.ac. kr ar X iv :1 80 4. 00 41 2v 1 [ he pth ] 2 A pr 2 01 8
On the GeV Emission of the Type I BdHN GRB 130427A

We propose that the inner engine of a type I binary-driven hypernova (BdHN) is composed of Kerr black hole (BH) in a non-stationary state, embedded in a uniform magnetic field B0 aligned with the BH rotation axis and surrounded by an ionized plasma of extremely low density of 10−14 g cm−3. Using GRB 130427A as a prototype, we show that this inner engine acts in a sequence of elementary impulses. Electrons accelerate to ultrarelativistic energy near the BH horizon, propagating along the polar axis, θ = 0, where they can reach energies of ∼1018 eV, partially contributing to ultrahigh-energy cosmic rays. When propagating with through the magnetic field B0, they produce GeV and TeV radiation through synchroton emission. The mass of BH, M = 2.31M⊙, its spin, α = 0.47, and the value of magnetic field B0 = 3.48 × 1010 G, are determined self consistently to fulfill the energetic and the transparency requirement. The repetition time of each elementary impulse of energy erg is ∼10−14 s at the beginning of the process, then slowly increases with time evolution. In principle, this “inner engine” can operate in a gamma-ray burst (GRB) for thousands of years. By scaling the BH mass and the magnetic field, the same inner engine can describe active galactic nuclei.
Homological Berglund-Hübsch mirror symmetry for curve singularities

Given a two-variable invertible polynomial, we show that its category of maximally-graded matrix factorisations is quasi-equivalent to the Fukaya-Seidel category of its Berglund-Hubsch transpose. This was previously shown for Brieskorn-Pham and $D$-type singularities by Futaki-Ueda. The proof involves explicit construction of a tilting object on the B-side, and comparison with a specific basis of Lefschetz thimbles on the A-side.

Rethinking Demand for A Varied Diet: The Role of Convenience Foods in Diversity Indices

The objective of this study is to develop a group based food diversity index that classifies convenience foods based on the basic food items they contain. This group based food diversity index is then applied to examine the relationship between the demand for food diversity, food expenditures and household characteristics. Further, findings using the new group based food diversity measure are compared to those obtained using a product code based food diversity index. Results are forthcoming.
Substantiation of the Parameters of the Central Distributor for Mineral Fertilizers

The main problem of distribution systems with a centralized metering seed actions of pneumatic planters is deficient feed-rate consistency of seeds in supply coulters. Thus, the purpose of the study is to develop the optimal ways of decreasing the irregular distribution of the seeds and mineral fertilizers in the coulters. In order to achieve this goal, it is suggested to give the air-and-seed mixture a certain form of organized motion by installing inside the transport line in front of dividing attachment of helical spiral of an original construction. The authors observe that the pneumatic pipeline with distributor with equal turns gives the most qualitative distribution of the material. Moreover, offset value of turns, particle velocity in different sections of the transportation, which were used to calculate their design parameters were theoretically justified. The practical value is that the submissions can be used in current practice of increasing the production of horticulture.

Open Research Online Is the disposition eﬀect related to investors’ reliance on System 1 and System 2 processes or their strategy of emotion regulation?

: We report research on investor susceptibility to the disposition effect, a financial decision-making bias where investors have a greater propensity to realize gains than realize losses. Despite theoretical arguments for the influence of emotions, research on susceptibility to this bias, on real investors, has relied primarily on socio-demographic explanations. Some experimental research on student populations has considered emotions more directly, but has not addressed differences in individual susceptibility and has not examined genuinely consequential investor behaviour in real markets. Our research addresses this gap by predicting susceptibility to the disposition effect based on investors’ reliance on intuitive (emotion mediated) cognition (System 1), analytical cognition (System 2) and the strategies they use to regulate their emotions. Using investors’ trading records from a UK sample, we measure their susceptibility to the disposition effect and assess, through a questionnaire, their reliance on Systems 1 and 2 cognitive processes and use of two emotion regulation strategies. Investors with higher reliance on System 1 processes have greater disposition effect, but reliance on System 2 processes is not related to the disposition effect. Investor reliance on reappraisal (an emotion regulation strategy of changing a situation’s meaning to alter its emotional impact) reduces their disposition effect. However, the use of expressive suppression (a strategy that inhibits emotion expressive behaviour) does not show a statistically significant relationship with this bias. These results suggest that investors’ intuitive emotional reactions explain susceptibility to bias, and that effective strategies of regulating emotions enable this bias to be overcome.
Investigation of Chemical Composition and Nutritional Value of Truffle Mushroom (Tuber nitidum Vittad.)

Truffles are very precious and expensive mushrooms owing to their distinctive aroma and great flavor. The present study was carried out to survey the nutritional value of Tuber nitidum , a wild edible mushroom belonging to Tuber genus. It was analyzed for fatty acid content, phenolic and volatile compounds and amino acid profile. The chemical composition of the studied mushroom species showed that this wild edible fungus is one of a rich phenolic and amino acid source. The characteristic mushroom odor compounds, 1-octen-3-ol (14.81%) and 1-octen-3-one (11.19%), have been also detected. However, it has been reported that p -hydroxy benzoic acid, gentisic acid, vanillic acid were found in ethyl acetate extract as phenolic ingredient. In the lipidic extract, it has been determined that 76.94% linoleic acid (C18:2n6c), 12.38% palmitic acid (C16:0), 6.38% oleic acid (C18:1n9c), 2.54% stearic acid (C18:0). The wild edible mushroom, Tuber nitidum , a wild edible mushroom, may be of value and importance in the food and pharmaceutical industry as a natural healthy product source.
Detection and prediction of land use change impact on the streamflow regime in Sahelian river basin, northwestern Nigeria

Detecting and predicting the impact of land use/land cover (LULC) changes on streamflow are crucial sources of information for the effective management and protection of land and water resources in Sahelian ecosystems such as the Hadejia river basin. In this study, LULC change detection was performed using ENVI, while the LULC modeling was conducted using the cellular automata (CA)–Markov in the IDRISI environment. However, the streamflow trend and variation were assessed using the Mann–Kendall (MK) trend test and the inverse distance weightage (IDW). Before the LULC modeling and projection (2030), the LULC was classified for 1990, 2000, and 2010 using supervised classification. Model output revealed a strong relationship between LULC and streamflow trend, thus, the decade 1990–2000 was the decade with high forest clearance and streamflow output, and consequently severe floods. However, the decade 2000–2010 witnessed land use expansion mainly via construction (3.4%). Meanwhile, the scenario will slightly change in the future as agriculture is projected to expand by about 9.3% from 2010 to 2030 due to the increased human population. Thus, food insecurity aggravated by climate change should be anticipated, and measures to avert/reduce their effects must be initiated.
EFFECT OF SULPHATE AND NITRATE ION ON THE EXTRACTION OF COPPER (II) METAL IONS FROM AQUEOUS MEDIA USING 2,2,2-TRICHLORO-1-(5-HYDROXY-3-METHYL-1-PHENYL-1H-PYRAZOL-4-YL)ETHANONE IN CHLOROFORM

The effect of sulphate and nitrate ions in aqueous media on the extraction of Cu (II) ions into 2,2,2-trichloro-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone (HTcP) solution in chloroform has been studied. The synergistic effect of butanol on the extraction of the metal ion was also examined. The results showed that extraction of Cu(II) ions was found to be more efficient from solutions of 0.05M HTcP between pH 4.00 – 8.00 over the pH range of 1.00 -8.00 studied with optimum percentage extraction above 90%. Increase in sulphate ion concentrations from 0.01M to 1.00M in the aqueous media resulted to a decrease in Cu (II) ion extracted and a shift of the extraction processes to higher pH values. This is due to the masking of the metal by anionic sulphate-copper complexes formed in solution. Similarly, increase in nitrate ion concentrations from 0.01M to 1.00M followed the same trend with optimum percentage extraction (%E) above 70%. Slight synergism occurred in the distribution of the metal ion into the chloroform-butanol phase and the extraction data showed that pH 1/2 shifted to lower values. Addition of butanol into the organic phase resulted in slight increase of optimum percentage extraction up to 99.57% from 99.15% in the absence of butanol as synergist over the pH range of 3.52-8.00 from aqueous buffer media containing 0.1M concentration of SO 4 2- ion. The slope analysis indicated that the Cu(TcP) 2 adduct complex species were extracted during all the extraction processes. The pH 1/2 and %E of the extraction systems were determined and used for explaining the various extraction processes observed. Keywords : Sulphate ion, Nitrate ion, aqueous media, copper (II), 2,2,2-trichloro-1-(5-hydroxy-3-methyl-1-phenyl-1 H -pyrazol-4-yl)ethanone.
Transient Kinetic Experiments within the High Conversion Domain: The Case of Ammonia Decomposition

In the development of catalytic materials, a set of standard conditions is needed where the kinetic performance of many samples can be compared. This can be challenging when a sample set covers a broad range of activity. Precise kinetic characterization requires uniformity in the gas and catalyst bed composition. This limits the range of convecting devices to low conversion (generally <20%). While steady-state kinetics offer a snapshot of conversion, yield and apparent rates of the slow reaction steps, transient techniques offer much greater detail of rate processes and hence more information as to why certain catalyst compositions offer better performance. In this work, transient experiments in two transport regimes are compared: an advecting differential plug flow reactor (PFR) and a pure-diffusion temporal analysis of products (TAP) reactor. The decomposition of ammonia was used as a model reaction to test three simple materials: polycrystalline iron, cobalt and a bimetallic preparation of the two. These materials presented a wide range of activity and it was not possible to capture transient information in the advecting device for all samples at the same conditions while ensuring uniformity. We push the boundary for the theoretical estimates of uniformity in the TAP device and find reliable kinetic measurement up to 90% conversion. However, what is more advantageous from this technique is the ability to observe the time-dependence of the reaction rate rather than just singular points of conversion and yield. For example, on the iron sample we observed reversible adsorption of ammonia and on cobalt materials we identify two routes for hydrogen production. From the time-dependence of reactants and product, the dynamic accumulation was calculated. This was used to understand the atomic distribution of H and N species regulated by the surface of different materials. When ammonia was pulsed at 550 °C, the surface hydrogen/nitrogen, (H/N), ratios that evolved for Fe, CoFe and Co were 2.4, 0.25 and 0.3 respectively. This indicates that iron will store a mixture of hydrogenated species while materials with cobalt will predominantly store NH and N. While much is already known about iron, cobalt and ammonia decomposition, the goal of this work was to demonstrate new tools for comparing materials over a wider window of conversion and with much greater kinetic detail. As such, this provides an approach for detailed kinetic discrimination of more complex industrial samples beyond conversion and yield.
Temperature distribution for magnetohydrodynamic flow in straight horizontal elliptical pipe

A study has been carried out on temperature distribution on Magnetohydrodynamic (MHD) fluid flow in a pipe of elliptical cross section. Fluid is electrically conducting, viscous and incompressible. Governing equations are partial differential equations comprising Ohm’s Law of electromagnetism, heat energy equation, equation of continuity and cross section of the pipe. Heat energy equation is converted into ordinary differential equation embracing similarity transformation and solved by Finite Element Method. Findings are in form of tables and contours and affirm that: Peak temperature of the fluid decreases at the centre of the pipe when Prandtl number is increased but increases on raising Hartmann number and Eckert number. In all the three situations, temperature diminishes towards the boundary of the pipe. Mathematics Subject Classification: 35Q05
The Choice of Tax Bases under Fiscal Federalism and the Unitary System

This paper analyzes the government's choice of three proportional tax bases (a consumption tax, a wage tax and a capital income tax) and its influence on the steady-state levels of capital accumulation and social welfare under fiscal federalism and the unitary system. We report two main findings: first, the system that uses a consumption and a capital income tax bases yields a higher steady state level of capital accumulation than that which uses a wage tax base. When each system uses the same tax base, then the steady state levels of capital accumulation under the two systems are equivalent. Second, the social welfare levels in fiscal federalism and the unitary system under a consumption tax base are equivalent if individual's rate of time preference just equal to the interest rate, while the social welfare levels in the two systems under the wage and capital income tax bases are equivalent if and only if the rate of time preference is equal to the population growth rate.
The persona in autobiographical game-making as a playful performance of the self

The paper at hand investigates forms and interpretations of author personae in autobiographical videogames. While, previously, autobiographical modes of expression have only been discussed in a few game-based artworks (Poremba 2007), the availability of free, easy-to-use tools like Twine and Ren’Py gradually affords autobiographical writing as a cultural technique outside of deliberately artistic endeavors. Therefore, the paper considers the creation and distribution of autobiographical games as a playful form of identity politics. For that purpose, a comparative content analysis (cf. e.g. Rossler 2012) of selected autobiographical games will be conducted, taking into account rhetorical and audiovisual elements but focusing on procedural design strategies and “bias” (Bogost 2008, 128). The corpus includes explicitly autobiographical sketches like Gravitation (2008) and Dys4ia (2012), but also cases in which the autobiographical characteristics are only implied like The Average Everyday Adventures of Samantha Browne (2016) as well as less polished, sometimes unfinished vignettes. This approach will be selectively complemented by a rhetorical analysis of paratextual elements such as developer statements and user comments. Play and games are increasingly recognized as modes of conceptualizing and expressing individual identity (Frissen et al. 2015, 35–36) that are particularly compatible with postmodern sensibilities. Consequently, the focus of the analysis will lie on how the implementation of the author personae as playable characters enable the developers to curate their identity online, both in terms of Moreno’s psychodrama (Moreno 1987) and Foucault’s technologies of the self (Aycock 1995).
Both a bioweapon and a hoax: the curious case of contradictory conspiracy theories about COVID-19

Abstract Amidst the flow of conspiracy theories (CTs) about the COVID-19 pandemic, many were logically incompatible. We aimed to map the psychological profile of their endorsers. Upon pretesting for familiarity and logical incompatibility, we choose eight pairs of contradictory COVID-19 CTs. Across three studies, a substantial portion of respondents (40%–42%) endorsed at least one pair. In Study 1 (N = 290), conspiracy mentality and doublethink, but not preference for consistency, meaningfully related to endorsement of contradictory CTs; doublethink contributed over and above other predictors. In two following studies we introduced indicators of superficial (Study 2; N = 281) and analytical (Study 3; N = 170) information-processing as predictors. The endorsers of contradictory CTs were more intuitive, prone to ontological confusions and pseudo-profound bullshit, less rational and less actively open-minded; doublethink again added to the prediction. We end by suggesting how the interventions should be tailored to address people with such distinct information-processing style.
NON-VEGETATED COMPOUND STRAIGHT CHANNELS

Floods are the most common natural disasters in Malaysia and have damaged structures, infrastructures, crops and even causes fatalities. It may also lead to erosion and sedimentation in rivers and this will result to complex river behaviour. A hydraulic laboratory experimental study was carried out. Also, flood flow and sediment transport in straight compound channels involving flow resistance, distribution of depth-averaged velocity, stream-wise vorticity patterns, channel bed morphology and bed load transport rate in non-vegetated compound straight mobile bed channels were investigated. The finding showed that the Darcy Weisbach friction factor f increased by 40% and 54% for floodplain and main channel, respectively when relative flood flow depth increase from 0.30 to 0.50. The small bed load transport rates of 0.09 g/s and 0.03 g/s for shallow and deep overbank flows, respectively were measured due to effect of very gentle or mild channel bed slope which was fixed at a gradient of 0.1%.
Characterization and modeling of the moisture diffusion behaviour of natural fibres

: Natural fibers have good properties to be used as reinforcement in composite materials. The main issue is their hydrophilic behavior. So we propose here to investigate the diffusion phenomenon in such fibres. First, a brief characterization of four vegetal fibers has been achieved. We show that all fibers have a similar composition and structure despite their different origin. Then, their moisture diffusive behavior was investigated. The samples were submitted to hygro-thermal aging either in total water immersion at room temperature or in an environmental chamber at 80% relative humidity and 23 (cid:1) C. Various predictive models were used to simulate experimental curves. Results show that all fibers exhibit a similar diffusive behavior in a same environment. In immersion, specimens show anomalous absorption kinetics and Langmuir theory actually describes very well the diffusion kinetics in such conditions, whereas the same fibers follow a Fickian diffusion when they are exposed to vapor during relative humidity aging.
A Promoter Polymorphism in the ALDH 2 Gene Affects Its Basal and Acetaldehyde / Ethanol-Induced Gene Expression in Human Peripheral Blood Leukocytes and HepG 2 Cells

Aims: To assess the effect of the −360G/A polymorphism in the promoter region of the human aldehyde dehydrogenase-2 (ALDH2) gene on its transcription, basal and acetaldehyde/ethanol-induced gene expression was examined by in vivo and in vitro experiments. Methods: Human peripheral blood leukocytes were collected before and after alcohol ingestion (0.4 g/kg body weight) in 21 healthy young Japanese volunteers with a deficient phenotype of ALDH2 (487Glu/Lys), and the levels of ALDH2 mRNA were quantified by real-time RT-PCR. The transcriptional activity of the ALDH2 promoter was investigated by a reporter assay using HepG2 cells in the presence or absence of acetaldehyde/ethanol. Results: The basal level of ALDH2 mRNA was significantly higher in −360A heterozygous subjects than in −360G homozygous subjects. In all subjects, regardless of the genotype, ALDH2 mRNA increased following ethanol ingestion. The promoter activity of a reporter plasmid for −360G was significantly lower than that of a reporter plasmid for −360A. Exposure to acetaldehyde induced a significant increase in the transcriptional activity of the −360G reporter, but not the −360A reporter. Conclusions: In vivo and in vitro experiments showed that the −360G allele has lower basal transcriptional activity than the −360A allele, whereas acetaldehyde/ethanol-induced gene expression, in general, seems to be more enhanced in individuals homozygous for the −360G allele than in those with the −360A allele. Thus, the promoter polymorphism may be involved in individual differences in acetaldehyde elimination.
