description: Dominated by a single, large-amplitude pulsation mode, the rapidly pulsating hot subdwarf
B star CS 1246 is a prime candidate for a long-term O−C diagram study. We collected
nearly 400 h of photometry with the 0.41-m Panchromatic Robotic Optical Monitoring and
Polarimetry Telescopes over a time-span of 14 months to begin looking for secular variations in
the pulse timings. Interestingly, the O−C diagram is dominated by a strong sinusoidal pattern
with a period of 14.1 d and an amplitude of 10.7 light-seconds. Underneath this sine wave is
a secular trend implying a decrease in the 371.7-s pulsational period of ˙P = −1.9 × 10−11,
which we attribute to the evolution of the star through the Hertzsprung–Russell diagram.
The sinusoidal variation could be produced by the presence of a low-mass companion, with
msin i ≃ 0.12M⊙, orbiting the subdwarf B star at a distance of 20 R⊙. An analysis of
the combined light curve reveals the presence of a low-amplitude first harmonic to the main
pulsation mode.

description: Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the breakdown of the nutritional photo-symbiosis with intracellular algae (genus: Symbiodinium). Here, we report that Stylophora pistillata from a highly diverse reef in the Gulf of Aqaba showed no signs of bleaching despite spending 1.5 months at 1–2°C above their long-term summer maximum (amounting to 11 degree heating weeks) and a seawater pH of 7.8. Instead, their symbiotic dinoflagellates exhibited improved photochemistry, higher pigmentation and a doubling in net oxygen production, leading to a 51% increase in primary productivity. Nanoscale secondary ion mass spectrometry imaging revealed subtle cellular-level shifts in carbon and nitrogen metabolism under elevated temperatures, but overall host and symbiont biomass proxies were not significantly affected. Now living well below their thermal threshold in the Gulf of Aqaba, these corals have been evolutionary selected for heat tolerance during their migration through the warm Southern Red Sea after the last ice age. This may allow them to withstand future warming for a longer period of time, provided that successful environmental conservation measures are enacted across national boundaries in the region.

description: Two new neolignans, myrifralignans F–G (14 and 18), four new diarylnonanoid derivatives, myrifragranones A–D (21–24), and 18 known compounds were isolated and structurally elucidated from nutmeg (Myristica fragrans Houtt.) seeds. The absolute configurations of these secondary metabolites were determined using the electronic circular dichroism technique. The inhibitory potential of these isolated compounds on soluble epoxide hydrolase (sEH) was investigated for the first time. Among them, malabaricones B and C (19 and 20) and four new compounds 21–24 displayed inhibitory activities against sEH, with IC50 values ranging from 14.24 to 46.35 µM. Additionally, the binding mechanism, key binding interactions, stability, and dynamic behaviour of the active compounds with the sEH enzyme were analysed using in silico molecular docking and dynamics simulations. Our findings suggest that nutmeg could become a promising natural source for discovering and developing new sEH inhibitors.

description: The centrality dependence of pseudorapidity density of charged particles and transverse energy is studied for a wide range of collision energies for heavy-ion collisions at midrapidity from 7.7 GeV to 5.02 TeV. A two-component model approach has been adopted to quantify the soft and hard components of particle production, coming from nucleon participants and binary nucleon-nucleon collisions, respectively. Within experimental uncertainties, the hard component contributing to the particle production has been found not to show any clear collision energy dependence from RHIC to LHC. The effect of centrality and collision energy in particle production seem to factor out with some degree of dependency on the collision species. The collision of Uranium-like deformed nuclei opens up new challenges in understanding the energy-centrality factorization, which is evident from the centrality dependence of transverse energy density, when compared to collision of symmetric nuclei.

description: Contribution analyses performed using IMPLAN data and software are an increasingly popular method for illustrating the importance of agriculture to state and local economies. Over the past decade, at least 24 states have used IMPLAN to conduct contribution of agriculture analyses at some level. In many cases, methods for conducting these analyses are described, however most descriptions aren’t presented in sufficient detail to allow an effective comparison of procedures used between studies. To further analyze methodological variations between contribution of agriculture studies, an online survey was developed and distributed to agricultural economists across the country. Survey questions focused on respondents’ choices related to trade flow models, multipliers, model customization procedures, and agricultural sector selection. Results of the survey show that, although there are general similarities in methodologies between researchers, no two agricultural economics researchers appear to perform contribution of agriculture analyses the same way. These results suggest a need for the development of standard procedures for use in conducting contribution of agriculture analyses, as this would function to increase transparency and comparability between studies.

description: A semiclassical, four-level model of a nanosecond, chirped pulse interacting with all optically accessible hyperfine states in the ultracold Rb atom is analyzed aiming at population inversion within $5S_{1/2}$ electronic state. The nature of two-photon adiabatic passage performed by such a single pulse having a bandwidth smaller than the hyperfine splitting of $5S_{1/2}$ state is investigated in the framework of the dressed state picture. It is shown that two dressed states are involved in the adiabatic dynamics of population inversion. The excited state manifold appeared to play an important mediating role in the mechanism of population transfer.

description: The Ebola virus is currently one of the most virulent pathogens for humans. The latest major outbreak occurred in Guinea, Sierra Leonne and Liberia in 2014. With the aim of understanding the spread of infection in the affected countries, it is crucial to modelize the virus and simulate it. In this paper, we begin by studying a simple mathematical model that describes the 2014 Ebola outbreak in Liberia. Then, we use numerical simulations and available data provided by the World Health Organization to validate the obtained mathematical model. Moreover, we develop a new mathematical model including vaccination of individuals. We discuss different cases of vaccination in order to predict the effect of vaccination on the infected individuals over time. Finally, we apply optimal control to study the impact of vaccination on the spread of the Ebola virus. The optimal control problem is solved numerically by using a direct multi-shooting method.

description: We discuss the nature of the velocity dispersion versus size relation for molecular clouds. In particular, we add to previous observational results showing that the velocity dispersions in molecular clouds and cores are not purely functions of the spatial scale but involve surface gas densities as well. We emphasize that hydrodynamic turbulence is required to produce the first condensations in the progenitor medium. However, as the cloud is forming, it also becomes bound, and gravitational accelerations dominate the motions. Energy conservation in this case implies |Eg| ∼Ek, in agreement with observational data, and providing an interpretation for two recent observational results: the scatter in the δv–R plane, and the dependence of the velocity dispersion on the surface density δv2/R∝Σ. We argue that the observational data are consistent with molecular clouds in a state of hierarchical and chaotic gravitational collapse, i.e. developing local centres of collapse throughout the whole cloud while the cloud itself is collapsing, and making equilibrium unnecessary at all stages prior to the formation of actual stars. Finally, we discuss how this mechanism need not be in conflict with the observed star formation rate.

A standard level of sugar addition to bread is 2% (flour base) but sweet baked goods including hamburger buns, hot dog buns and some sandwich bread contain more than 10% sucrose. This study aimed to provide an integrated assessment of different strategies for sugar-reduced bread by using isomaltooligosaccharides (IMO) as bulk sweetening agent, polysaccharide hydrolases to generate sugars from flour polysaccharides, and sourdough. Trained panel sensory analyses of the intensity of sour and sweet tastes were compared to the concentration of organic acids and the sugar concentration of bread. Sourdough fermentation reduced the sweet taste intensity of bread produced with 9% sucrose. This effect was more pronounced with Leuconostoc mesenteroides, which converts fructose to mannitol with concomitant production of acetate. Addition of up to 20% sourdough fermented with Weissella cibaria 10 M, which does not produce mannitol and less acetate when compared to L. mesenteroides, did not substantially reduce the sweet taste intensity. Bread produced with 9% IMO tasted less sweet than bread prepared with 9% sucrose but partial replacement of sucrose with IMO maintained the sweet taste intensity. Addition of 4.5% IMO in combination with W. cibaria sourdough, amyloglucosidase and the fructosidase FruA enabled production of bread with 50% reduced sucrose addition while maintaining the sweet taste intensity. In conclusion, the single use of a sweet bulking agent, of amyloglucosidase or fructanases or the use of sourdough alone, did not maintain the sweet taste intensity of sugar-reduced bread, however, a combination of the three approaches allowed a reduction of sucrose addition without reducing the sweet taste intensity.

description: We recently reported the first identification of rotational transitions of methyl formate (HCOOCH$_{3}$) in the second torsionally excited state toward Orion Kleinmann-Low (KL) observed with the Nobeyama 45 m telescope. In combination with the identified transitions of methyl formate in the ground state and the first torsional excited state, it was found that there is a difference in rotational temperature and vibrational temperature, where the latter is higher. In this study, high spatial resolution analysis by using Atacama Large Millimeter/Submillimeter Array (ALMA) science verification data was carried out to verify and understand this difference. Toward the Compact Ridge, two different velocity components at 7.3 and 9.1 km s$^{-1}$ were confirmed, while a single component at 7.3 km s$^{-1}$ was identified towards the Hot Core. The intensity maps in the ground, first, and second torsional excited states have quite similar distributions. Using extensive ALMA data, we determined the rotational and vibrational temperatures for the Compact Ridge and Hot Core by the conventional rotation diagram method. The rotational temperature and vibrational temperatures agree for the Hot Core and for one component of the Compact Ridge. At the 7.3 km s$^{-1}$ velocity component for the Compact Ridge, the rotational temperature was found to be higher than the vibrational temperature. This is different from what we obtained from the results by using the single-dish observation. The difference might be explained by the beam dilution effect of the single-dish data and/or the smaller number of observed transitions within the limited range of energy levels ($\leq$30 K) of $E_u$ in the previous study.

description: Surface structuring offers great potential for modifying frictional properties for various applications, such as complex forming processes like sheet-bulk metal forming. The production of surface structures in micrometre range is challenging for manufacturing processes in particular when machining hard-to-cut materials like hardened tool steels. Precise electrochemical machining (PECM) has great potential for surface structuring and shaping of metallic materials regardless of their hardness with high surface quality and comparatively very short process times, especially when structuring large areas and batches. Micro structuring of hardened tool steel surfaces using PECM is investigated in this paper. Surfaces of high-speed tool steel and hot-work tool steel are structured using a commercial PECM machine with neutral solution of NaNO3 as electrolyte. In a process sequence, PECM tools were manufactured in a first step producing selected structures by high-feed milling (HFM) and micromilling (MM). In a further process step, the negative shape of these complex structures was machined using the PECM process. Through this process chain, new types of structures can be generated which have different tribological properties than their corresponding negative shapes of HFM and MM structures. Tribological behaviour and wear properties of the structured surfaces are investigated through ring compression test (RCT).

Decontamination of low aw foods without impairing the food quality is challenging, particularly for sprouting seeds. This study aimed to explore the lethality of high pressure carbon dioxide (HPCD) to Salmonella enterica, E. coli AW1.7, A. niger, P. roquforti, and Fusarium on beans, cereal grains, and ground pepper. The optimal antimicrobial effect of HPCD was achieved by equilibration of the aw to 0.75, followed by soaking in water and treatments with water-saturated CO2. HPCD reduced the viable cell counts of E. coli and Salmonella by 3–10 log(CFU/g), and prevented fungal growth during 10 d of incubation. More than 90% of mung beans germinated but the germination of oats was impaired after fungicidal or bactericidal treatments with HPCD. Overall, HPCD can be a promising antimicrobial treatment but treatment parameters need to be optimized for each type of seed.

description: PG 1351+489 is one of the 20 DBVs – pulsating helium-atmosphere white dwarf stars – known and has the simplest power spectrum for this class of star, making it a good candidate to study cooling rates. We report accurate period determinations for the main peak at 489.334 48 s and two other normal modes using data from the Whole Earth Telescope (WET) observations of 1995 and 2009. In 2009, we detected a new pulsation mode and the main pulsation mode exhibited substantial change in its amplitude compared to all previous observations. We were able to estimate the star's rotation period, of 8.9 h, and discuss a possible determination of the rate of period change of (2.0 ± 0.9) × 10−13 s s −1, the first such estimate for a DBV.

description: We report the discovery of two new Galactic candidate luminous blue variable (LBV) stars via detection of circular shells (typical of confirmed and candidate LBVs) and follow‐up spectroscopy of their central stars. The shells were detected at 22 μm in the archival data of the Mid‐Infrared All Sky Survey carried out with the Wide‐field Infrared Survey Explorer (WISE). Follow‐up optical spectroscopy of the central stars of the shells conducted with the renewed Southern African Large Telescope (SALT) showed that their spectra are very similar to those of the well‐known LBVs P Cygni and AG Car, and the recently discovered candidate LBV MN112, which implies the LBV classification for these stars as well. The LBV classification of both stars is supported by detection of their significant photometric variability: one of them brightened in the R and I bands by 0.68 ± 0.10 and 0.61 ± 0.04 mag, respectively, during the last 13–18 years, while the second one (known as Hen 3‐1383) varies its B, V, R, I and Ks brightnesses by ≃0.5–0.9 mag on time‐scales from 10 d to decades. We also found significant changes in the spectrum of Hen 3‐1383 on a time‐scale of ≃3 months, which provides additional support for the LBV classification of this star. Further spectrophotometric monitoring of both stars is required to firmly prove their LBV status. We discuss a connection between the location of massive stars in the field and their fast rotation, and suggest that the LBV activity of the newly discovered candidate LBVs might be directly related to their possible runaway status.

description: We study analytically the plasmonic modes in the graphene-coated dielectric nanowire, based on the explicit form of nonlinear surface conductivity of graphene. The propagation constants of different plasmonic modes can be tuned by the input power at the order of a few tenths of mW. The lower and upper mode bifurcation branches are connected at the limitation value of the input power. Moreover, due to the nonlinearity of graphene, the dispersion curves of plasmonic modes at different input powers form an energy band, which is in sharp contrast with the single dispersion curve in the limit of zero input power.

description: Extrusion processing has a wide variety of applications in the food industry due to its easily modifiable system. Expansion and texturization phenomena can be employed as restructuring tools to generate new products and extend the application of food ingredients. This research explored how expansion and texturization processes impact the structure formation of expanded pea starch and low moisture meat analogs made from four different plant protein sources. Two separate studies were conducted.
description: Pea starch was extruded with varying talc and calcium carbonate levels (0, 0.25, 1, and 2%) to explore the expansion phenomenon to assess heterogeneous nucleation and their impact on expansion characteristics. Air cell count, with significantly higher values from the control indicating better nucleating efficiency, improved as the screw speed increased above 350 rpm with higher nucleating agent inclusion levels (≥1%) of calcium carbonate. In contrast, the air cell count for talc-containing extrudates improved with increasing nucleating agent inclusion levels regardless of screw speed. While nucleating efficiency improved with nucleating agents, the additives promoted flow instabilities as indicated by extrudate ridged surfaces.
description: The second study researched the novel application of plant-based textured proteins for cultured meat production. Five protein concentrates/isolates (wheat protein concentrate, faba bean protein isolate, mung bean protein concentrate, and two different soy isolates) individually blended with cornstarch were texturized under low moisture conditions (22.5-35% wet basis) to create low moisture meat analogs. Blends were extruded at their respective optimal processing conditions, and C2C12 mouse myoblast cells were cultured onto the structures for 14 days. Cell cultures were cytocompatible with all the proteins tested, as indicated by live/dead stain imaging, where the cells survived after 1 and 14 days of culture. Alignment of the proteins, as described by the anisotropic index, provided physical cues that promoted cell alignment. Mechanical properties of the extrudates appeared to influence cell attachment. Low elastic moduli appeared to help maintain cell attachment post-differentiation, while higher elastic moduli promoted cell detachment post-differentiation. Cells exhibited superior attachment behavior on the wheat-based extrudate. The work presented has expanded the options of compatible scaffolding materials for cultured meat production. However, it demonstrates the need to explore and optimize different processing parameters, which influence the mechanical properties of texturized proteins, to improve the long-term attachment of muscle cells.

description: We present follow-up observations of the pulsating subdwarf B (sdB) star EC 01541–1409 as part of our efforts to resolve pulsation spectra for use in asteroseismological analyses. This paper reports on data obtained from a single-site campaign, during 2008, and a multisite campaign, during 2009. From limited 2008 data, we were able to clearly resolve and pre-whiten 24 periods. A subsequent multisite campaign spanning nearly 2 months found over 30 individual periodicities most of which were unstable in amplitude and/or phase. Pulsation amplitudes were found to the detection limit, meaning that further observations would likely reveal more periodicities.

The bacterial conversion of glutamine to glutamate is catalyzed by glutamine-amidotransferases or glutaminases. Glutamine deamination contributes to the formation of the bioactive metabolites glutamate, γ-aminobutyrate (GABA) and γ-glutamyl peptides, and to acid resistance. This study aimed to investigate the distribution of glutaminase(s) in lactobacilli, and to evaluate their contribution in L. reuteri to amino acid metabolism and acid resistance. Phylogenetic analysis of the glutaminases gls1, gls2 and gls3 in the genus Lactobacillus demonstrated that glutaminase is exclusively present in host-adapted species of lactobacilli. The disruption gls1, gls2 and gls3 in L. reuteri 100-23 had only a limited effect on the conversion of glutamine to glutamate, GABA, or γ-glutamyl peptides in sourdough. The disruption of all glutaminases in L. reuteri 100-23Δgls1Δgls2Δgls3 but not disruption of gls2 and gls3 eliminated the protective effect of glutamine on the survival of the strain at pH 2.5. Glutamine also enhanced acid resistance of L. reuteri 100-23ΔgadB and L. taiwanensis 107q, strains without glutamate decarboxylase activity. Taken together, the study demonstrates that glutaminases of lactobacilli do not contribute substantially to glutamine metabolism but enhance acid resistance. Their exclusive presence in host-adapted lactobacilli provides an additional link between the adaptation of lactobacilli to specific habitats and their functionality when used as probiotics and starter cultures.

description: Alexopoulos proved that on a finitely generated virtually nilpotent group, the restriction of a harmonic function of polynomial growth to a torsion-free nilpotent subgroup of finite index is always a polynomial in the Mal'cev coordinates of that subgroup. For general groups, vanishing of higher-order discrete derivatives gives a natural notion of polynomial maps, which has been considered by Leibman and others. We provide a simple proof of Alexopoulos's result using this notion of polynomials, under the weaker hypothesis that the space of harmonic functions of polynomial growth of degree at most k is finite dimensional. We also prove that for a finitely generated group the Laplacian maps the polynomials of degree k surjectively onto the polynomials of degree k - 2. We then present some corollaries. In particular, we calculate precisely the dimension of the space of harmonic functions of polynomial growth of degree at most k on a virtually nilpotent group, extending an old result of Heilbronn for the abelian case, and refining a more recent result of Hua and Jost.

description: We present the orbital and physical parameters of a newly discovered low-mass detached eclipsing
binary from the All-Sky Automated Survey (ASAS) data base: ASAS J011328–3821.1 A,
which is a member of a visual binary system with the secondary component separated by about
1.4 arcsec. The radial velocities have been calculated from the high-resolution spectra obtained
with the 1.9-m Radcliffe telescope/Grating Instrument for Radiation Analysis with a Fibre-Fed
Echelle (GIRAFFE) spectrograph, the 3.9-m Anglo-Australian Telescope (AAT)/University
College London Echelle Spectrograph (UCLES) and the 3.0-m Shane telescope/Hamilton
Spectrograph (HamSpec) on the basis of the TODCOR technique and the positions of the Hα
emission lines. For the analysis, we have used V- and I-band photometry obtained with the
1.0-m Elizabeth telescope and the 0.41-m Panchromatic Robotic Optical Monitoring and
Polarimetry Telescopes (PROMPT), supplemented with the publicly available ASAS light
curve of the system.
We have found that ASAS J011328–3821.1 A is composed of two late-type dwarfs, which
have masses of M1 = 0.612 ± 0.030 M⊙ and M2 = 0.445 ± 0.019 M⊙ and radii of R1 =
0.596 ± 0.020 R⊙ and R2 = 0.445 ± 0.024 R⊙. Both show a substantial level of activity,
which manifests in strong Hα and Hβ emission and the presence of cool spots. The influence
of the third light on the eclipsing pair properties has also been evaluated and the photometric
properties of component B have been derived. A comparison with several popular stellar
evolution models shows that the system is on its main-sequence evolution stage and that it
is probably more metal-rich than the Sun. We have also found several clues to suggest that
component B itself is a binary composed of two nearly identical ∼0.5-M⊙ stars.

description: Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the breakdown of the nutritional photo-symbiosis with intracellular algae (genus: Symbiodinium). Here, we report that Stylophora pistillata from a highly diverse reef in the Gulf of Aqaba showed no signs of bleaching despite spending 1.5 months at 1–2°C above their long-term summer maximum (amounting to 11 degree heating weeks) and a seawater pH of 7.8. Instead, their symbiotic dinoflagellates exhibited improved photochemistry, higher pigmentation and a doubling in net oxygen production, leading to a 51% increase in primary productivity. Nanoscale secondary ion mass spectrometry imaging revealed subtle cellular-level shifts in carbon and nitrogen metabolism under elevated temperatures, but overall host and symbiont biomass proxies were not significantly affected. Now living well below their thermal threshold in the Gulf of Aqaba, these corals have been evolutionary selected for heat tolerance during their migration through the warm Southern Red Sea after the last ice age. This may allow them to withstand future warming for a longer period of time, provided that successful environmental conservation measures are enacted across national boundaries in the region.

description: We find the defining equations of Rees rings of linearly presented height three Gorenstein ideals. To prove our main theorem we use local cohomology techniques to bound the maximum generator degree of the torsion submodule of symmetric powers in order to conclude that the defining equations of the Rees algebra and the special fiber ring have the same image in the symmetric algebra. We show that this image is the unmixed part of the ideal generated by the maximal minors of a matrix of linear forms which is annihilated by a vector of indeterminates, and otherwise has maximal possible grade. An important step of the proof is the calculation of the degree of the variety parametrized by the forms generating the grade three Gorenstein ideal.
