The lasting smell of emotions: The effects of reutilizing fear sweat samples
Authors: Gomes Nuno , Silva Fábio , Semin Gün R. 
Published: May 2020

AbstractA growing body of research has shown that human apocrine sweat carries information about the emotional state of its donor. Exposure to sweat produced in a fear-inducing context triggers in its receivers a simulacrum of this emotional state, as evidenced by increased medial frontalis and corrugator supercilii (facial electromyography; fEMG) activity – two facial muscles involved in the display of fear facial expressions. However, despite the increased interest in the effects of emotional sweat, little is known about the properties of these chemical sweat samples. The goal of this study was to examine whether a second application of the same sweat sample would yield reliable results. Specifically, we assessed whether sweat samples collected from Portuguese males (N = 8) in fear (vs. neutral)-inducing contexts would produce similar fEMG activations (i.e., in the medial frontalis and corrugator supercilii) in female receivers (N = 60) across two independent applications (the first with Dutch and the second with Portuguese receivers). Our findings showed that exposure to fear (vs. neutral) sweat resulted in higher activation of both muscles compared with neutral odors, revealing a similar data pattern across the two applications and underlining the feasibility of reusing emotional sweat samples. The implications of these findings for properties of these sweat volatiles are discussed.

Published: May 2020

Coconut mite, Aceria guerreronis, Keifer, which made its first appearance as pest in Mexico in 1965 as reported by Keifer, has spread far and wide. Now that 37 years have passed. Research efforts have been made on various aspects of this pest like, origin, occurrence, dispersal, symptoms, population dynamics, management practices like chemical control, bio control, cultural practices, varietal resistance/ tolerances, natural enemies, phytosanitary efforts etc. Two international seminars/ workshops have been held. Many group discussions, steering committee meetings, etc. were also held. Lots of publications have come. An earnest attempt has been made to collect the available literature on this pest which can benefit the member countries and others to know what has been done and what directions one has to move for future research and development. However, this bibliography is not the completed one. There may be many more and we will update as and when we get access to those references. We are confident that this bibliography will help to avoid duplication and take up need based research and development on Eriophyid mite.
INVESTIGATION OF THE FEASIBILITY OF CONSTRUCTING A MAP FOR COCONUT WITH SEVERAL F2 FAMILIES USING COMPUTER-SIMULATED DATA
Authors: C. K. Bandaranayake  
Published: May 2020

A computer simulation was performed using RiceSim computer software to explore the practicability of combining several different F2 populations together through JoinMap to mimic the real available coconut mapping populations, and found that it was very successful. JoinMap would be able to map all 16 chromosomes which covered the map length of 1540 cM except for a single marker on chromosome 8. The largest marker interval was 32 cM at the bottom of chromosome 3 and all other markers were evenly distributed along the chromosomes maintaining the space around 12-30 cM between them.
NEW WAY OF CONTROLLING Oryctes monoceros (COLEOPTERA, DYNASTIDAE), A COCONUT PEST IN GHANA
Authors: René Philippe  , S.K. Dery  
Published: May 2020

Oryctes monoceros is one of the most dangerous pests in young coconut and oil palm plantings throughout West Africa.
This species is controlled using different methods that can be applied in combination as part of IPM. The first naturally involves eliminating all larva sites, consisting of dead or felled coconut or oil palm stems. Rapidly covering felled stems with a cover crop can keep the populations of this pest down to a very low level. When adults attack, frequent monitoring of young plantings is recommended, as is the removal of adults from their galleries using a metal mini-harpoon. Chemical control with Lambda-Cyhalothrin reduces damage to seedlings, particularly as that product has good repellent properties. It remains effective for around a month.
Physical control has been developed, using old fishing nets rolled into balls and inserted in the axils of young fronds. This method is highly effective, cheaper than other types of control, does not pollute and is not toxic for handlers. Adults trapped by the rolled up fishing nets, which eventually die, attract other adults that are trapped in turn, thereby increasing the efficiency of the method.
New data on a cultural control method against coconut lethal yellowing in Ghana
Authors: R. Philippe  , S. K. Dery  , J. Nkansa Poku  
Published: May 2020

Lethal yellowing disease has been rife in West Africa, especially Ghana, since 1932. In the 1990s, the first operations to fell diseased coconut palms at an early stage showed that this substantially slowed down the spread of the disease.
Trial conducted in 1995 showed that early felling of diseased coconut palms, even without prior treatment, considerably slowed down the spread of the disease. Replications of this action in several other plots kept them healthy for many years. These positive results made it possible to obtain funding from Agence française de Développement (AFD) to maintain a "sanitary cordon" in the far West of the Western Region of Ghana, near the Ivorian border, where there is a wide area of coconut palms.
Bud rot disease of coconut in relation to endemic spots in Kerala state, India
Authors: ROHINI IYER Rohini Iyer , A.R. Rasmi  
Published: May 2020

In India bud rot is quite common on the West and East Coast tracts. A random survey on bud rot disease of coconut, caused by Phytophthora palmivora But.l, carried out in Kasaragod, Kannur and Calicut districts of Kerala revealed that, there is correlation between the disease incidence and the location of the palms. The disease incidence was high in the hilly tracts when compared to that of the plains. Studies on the survival of P. palmivora propagules in nature revealed that the pathogen survives in the crown, soil and roots of healthy and diseased palms. However, the percentage of survival was high in the endemic areas-Mandapam (Kasaragod District), Josegiri (Kannur Dist.) and Kuttiadi (Kozhikode Dist.), both in the case of diseased and healthy palms compared to that of areas with lesser disease incidence. The temperature and humidity in the coconut growing tracts of hilly areas of Kasaragod, Kannur and Kozhikode districts are suitable for the survival of the pathogen in the crown during almost all months, resulting in the high frequency of disease incidence during monsoon season and continued infection up to January. Examination of the rain water collected from bud rot affected coconut gardens also indicated that the pathogen surviving in the crown debris can act as a source of inoculum, which spreads to the neighboring palms through rain splashes. Based on the weather data it is possible to predict the bud rot incidence well in advance.
Nutrition and fertilization management of embryo cultured Makapuno Tall (ECMAKT) seedlings

Published: May 2020

A two-year nursery study on ECMAKT coconut seedlings was conducted at the Philippine Coconut Authority - Albay Research Center, Guinobatan, Albay to know the effects of applying different rates of complete fertilizer (14-14-14 fortified with micronutrients) and a foliar fertilizer on the vegetative growth and leaf nutrient status of ECMAKT seedlings.

The application of complete NPK fertilizer (14-14-14) at 6-9 g/seedling significantly produced taller seedlings with bigger girth size and more number of living fronds from 2 to 12 months from initial fertilization. The applied rates of complete fertilizer (6-9 g 14-14-14/seedling) on ECMAKT seedlings indicates that the levels of nutrient application (fertilization) is significantly much lower than that of the average rates used in growing ordinary seednuts (seedlings attached to unhusked nuts) in the nursery. The application of foliar fertilizer was ineffective even over the unfertilized ECMAKT seedlings.

The better growth of ECMAKT seedlings in terms of their girth, plant height and total living fronds produced were significantly associated with higher levels of leaf K, Cl, and Mn, and lower leaf Na, but with likely adequate leaf P, Mg, S, B, Zn, Cu and Fe based from leaf number 3 (12 month old ECMAKT seedling).

The study clearly indicates the necessity of applying inorganic fertilizer i.e. complete fertilizer (14-14-14 fortified with micronutrients) at the moderate rates of 6-9 g/seedling during the nursery stage for proper nutrition and fertilization management to ensure healthy and good quality ECMAKT planting material.
Evaluation of crop management options for replanting of coconut plantations devastated by lethal yellowing disease in Ghana

Published: May 2020

Evaluation of four coconut management options was carried out from May 1999 to May 2004 in the coconut belt of the Western and Central Regions of Ghana for replanting of coconut plantations devastated by the Cape St Paul Wilt Disease of Ghana. Coconut hybrid identified for the replanting was MYD x VTT. On fertile soils just intercropping of inter-rows with food crops proved appropriate for managing the coconut hybrid successfully. On low fertile soils however, fertilization was required in addition to intercropping for proper management of the hybrid. Where intercrops were fertilized the coconut palms benefited from the residual effect. While Pueraria phaseoloides did not have any visible impact, Cassia siamea was antagonistic to growth and development of the young coconut hybrid. Fertilized intercropping was more profitable especially on low fertile soils.
Roland Barthes: The Proust Variations
Authors: Baldwin Thomas 
Published: May 2020

By confronting the singularity of the relationship between two exemplary writers of the last century, this book challenges and reinvigorates our notions of what art and criticism – literary or otherwise – can do. While it takes Roland Barthes’s encounters with Marcel Proust’s monumental masterpiece À la recherche du temps perdu as its specific focus, the implications of its argument are far-reaching. Indeed, the book argues that Barthes’s writing on Proust’s work between the early 1950s and 1980 (including a substantial set of unpublished notes for a seminar delivered at the University of Rabat in 1969–1970) proposes not only a critical culture of Proust that is productively inconsistent, but also, more generally, a fresh understanding of criticism as a creative activity that embraces insecurity and variation as it refuses to remain fixed upon reassuringly stable themes, meanings and interpretations.
Galaxy Cluster Contribution to the Diffuse Extragalactic Ultraviolet Background
Authors: Welch Brian , McCandliss Stephan , Coe Dan 
Published: May 2020

Abstract
The diffuse ultraviolet background radiation has been mapped over most of the sky with 2′ resolution using data from the Galaxy Evolution Explorer survey. We utilize this map to study the correlation between the UV background and clusters of galaxies discovered via the Sunyaev–Zeldovich effect in the Planck survey. We use only high Galactic latitude (

) galaxy clusters to avoid contamination by Galactic foregrounds, and we only analyze clusters with a measured redshift. This leaves us with a sample of 142 clusters over the redshift range of 0.02 ≤ z ≤ 0.72, which we further subdivide into four redshift bins. In analyzing our stacked samples binned by redshift, we find evidence for a central excess of UV background light compared to local backgrounds for clusters with z < 0.3. We then stacked these z < 0.3 clusters to find a statistically significant excess of 12 ± 2.3 photon cm−2 s−1 sr−1 Å−1 over the median of ∼380 photon cm−2 s−1 sr−1 Å−1 measured around random blank fields. We measure the stacked radial profile of these clusters, and find that the excess UV radiation decays to the level of the background at a radius of ∼1 Mpc, roughly consistent with the maximum radial extent of the clusters. Analysis of possible physical processes contributing to the excess UV brightness indicates that non-thermal emission from relativistic electrons in the intracluster medium and faint, unresolved UV emission from cluster member galaxies and intracluster light are likely the dominant contributors.

Abstract
The radial velocities of 2768 fundamental-mode RR Lyrae stars (RRLs) toward the southern Galactic bulge are presented, spanning the southern bulge from −8° < l < + 8° and −3° < b < −6°. Distances derived from the pulsation properties of the RRLs are combined with Gaia proper motions to give constraints on the orbital motions of 1389 RRLs. The majority (∼75%) of the bulge RRLs have orbits consistent with these stars being permanently bound to <3.5 kpc from the Galactic Center, similar to the bar. However, unlike the bulge giants, the RRLs exhibit slower rotation and a higher velocity dispersion. The higher velocity dispersion arises almost exclusively from halo interlopers passing through the inner Galaxy. We present 82 stars with space velocities ≳500 km s−1 and find that the majority of these high-velocity stars are halo interlopers; it is unclear if a subsample of these stars with similar space velocities has a common origin. Once the 25% of the sample represented by halo interlopers is cleaned, we can clearly discern two populations of bulge RRLs in the inner Galaxy. The first population of RRLs is not as tightly bound to the Galaxy (but is still confined to the inner ∼3.5 kpc) and is both spatially and kinematically consistent with the barred bulge. The second population is more centrally concentrated and does not trace the bar. One possible interpretation is that this population was born prior to bar formation, as their spatial location, kinematics, and pulsation properties suggest, possibly from an accretion event at high redshift.
Magnetic Field Geometry and Composition Variation in Slow Solar Winds: The Case of Sulfur
Authors: Kuroda Natsuha , Laming J. Martin 
Published: May 2020

Abstract
We present an examination of the first ionization potential (FIP) fractionation scenario, invoking the ponderomotive force in the chromosphere and its implications for the source(s) of slow-speed solar winds by using observations from The Advanced Composition Explorer (ACE). Following a recent conjecture that the abundance enhancements of intermediate FIP elements, S, P, and C, in slow solar winds can be explained by the release of plasma fractionated on open fields, though from regions of stronger magnetic field than usually associated with fast solar wind source regions, we identify a period in 2008 containing four solar rotation cycles that show repeated pattern of sulfur abundance enhancement corresponding to a decrease in solar wind speed. We identify the source regions of these slow winds in global magnetic field models, and find that they lie at the boundaries between a coronal hole and its adjacent active region, with origins in both closed and open initial field configurations. Based on magnetic field extrapolations, we model the fractionation and compare our results with element abundances measured by ACE to estimate the solar wind contributions from open and closed fields, and to highlight potentially useful directions for further work.
The Parameter-free Finger-of-God Model and Its Application to 21 cm Intensity Mapping

Published: May 2020

Abstract
Using the galaxy catalog built from ELUCID N-body simulation and the semianalytical galaxy formation model, we have built a mock H i intensity mapping map. We have implemented the Finger-of-God (FoG) effect in the map by considering the galaxy H i gas velocity dispersion. By comparing the H i power spectrum in redshift space with a measurement from the IllustrisTNG simulation, we have found that the FoG effect can explain the discrepancy between current mock maps built from the N-body simulation and the IllustrisTNG simulation. Then we built a parameter-free FoG model and a shot-noise model to calculate the H i power spectrum. We found that our model can accurately fit both the monopole and quadrupole moments of the H i matter power spectrum. Our approach to building the mock H i intensity map and the parameter-free FoG model will be useful for upcoming 21 cm intensity mapping experiments, such as CHIME, Tianlai, BINGO, FAST, and SKA. It is also vital for studying nonlinear effects in 21 cm intensity mapping.
A New Method to Measure Hubble Parameter H(z) Using Fast Radio Bursts
Authors: Wu Q. , Yu H. , Wang F. Y. 
Published: May 2020

Abstract
The Hubble parameter H(z) is directly related to the expansion of our universe. It can be used to study dark energy and constrain cosmology models. In this paper, we propose that H(z) can be measured using fast radio bursts (FRBs) with redshift measurements. We use dispersion measures contributed by the intergalactic medium, which is related to H(z), to measure the Hubble parameter. We find that 500 mocked FRBs with dispersion measures and redshift information can accurately measure Hubble parameters using Monte Carlo simulation. The maximum deviation of H(z) from the standard ΛCDM model is about 6% at redshift z = 2.4. We also test our method using Monte Carlo simulation. A Kolmogorov–Smirnov (K-S) test is used to check the simulation. The p-value of the K-S test is 0.23, which confirms internal consistency of the simulation. In the future, more localizations of FRBs make it an attractive cosmological probe.
Simulating Solar Flare Irradiance with Multithreaded Models of Flare Arcades

Published: May 2020

Abstract
Understanding how energy is released in flares is one of the central problems of solar and stellar astrophysics. Observations of high-temperature flare plasma hold many potential clues as to the nature of this energy release. It is clear, however, that flares are not composed of a few impulsively heated loops, but are the result of heating on many small-scale threads that are energized over time, making it difficult to compare observations and numerical simulations in detail. Several previous studies have shown that it is possible to reproduce some aspects of the observed emission by considering the flare as a sequence of independently heated loops, but these studies generally focus on small-scale features while ignoring the global features of the flare. In this paper, we develop a multithreaded model that encompasses the time-varying geometry and heating rate for a series of successively heated loops composing an arcade. To validate, we compare with spectral observations of five flares made with the MinXSS CubeSat, as well as light curves measured with GOES/XRS and SDO/AIA. We show that this model can successfully reproduce the light curves and quasi-periodic pulsations in GOES/XRS, the soft X-ray spectra seen with MinXSS, and the light curves in various AIA passbands. The AIA light curves are most consistent with long-duration heating, but elemental abundances cannot be constrained with the model. Finally, we show how this model can be used to extrapolate to spectra of extreme events that can predict irradiance across a wide wavelength range, including unobserved wavelengths.
Pre-common-envelope Mass Loss from Coalescing Binary Systems
Authors: MacLeod Morgan , Loeb Abraham 
Published: May 2020

Abstract
Binary systems undergoing unstable Roche Lobe overflow spill gas into their circumbinary environment as their orbits decay toward coalescence. In this paper, we use a suite of hydrodynamic models of coalescing binaries involving an extended donor and a more compact accretor. We focus on the period of unstable Roche Lobe overflow that ends as the accretor plunges within the envelope of the donor at the onset of a common envelope phase. During this stage, mass is removed from the donor and flung into the circumbinary environment. Across a wide range of binary mass ratios, we find that the mass expelled as the separation decreases from the Roche limit to the donor’s original radius is of the order of 25% of the accretor’s mass. We study the kinematics of this ejecta and its dependencies on binary properties and find that it assembles into a toroidal circumbinary distribution. These circumbinary tori have approximately constant specific angular momenta due to momentum transport by spiral shocks launched from the orbiting binary. We show that an analytic model with these torus properties captures many of the main features of the azimuthally averaged profiles of our hydrodynamic simulations. Our results, in particular the simple relationship between accretor mass and expelled mass and its spatial distribution, may be useful for interpreting stellar coalescence transients like luminous red novae and initializing hydrodynamic simulations of the subsequent common envelope phase.

Abstract
In the episodic accretion scenario, a large fraction of the protostellar mass accretes during repeated and large bursts of accretion. Since outbursts on protostars are typically identified at specific wavelengths, interpreting these outbursts requires converting this change in flux to a change in total luminosity. The Class I young stellar object EC 53 in the Serpens Main cloud has undergone repeated increases in brightness at 850 μm that are likely caused by bursts of accretion. In this study, we perform two- and three-dimensional continuum radiative transfer modeling to quantify the internal luminosity rise in EC 53 that corresponds to the factor of ∼1.5 enhancement in flux at 850 μm. We model the spectral energy distribution and radial intensity profile in both the quiescent and outburst phases. The internal luminosity in the outburst phase is ∼3.3 times brighter than the luminosity in the quiescent phase. The radial intensity profile analysis demonstrates that the detected submillimeter flux variation of EC 53 comes from the heated envelope by the accretion burst. We also find that the role of external heating of the EC 53 envelope by the interstellar radiation field is insignificant.
