description: The emergence of clustering and coarsening in crowded ensembles of self-propelled agents is studied using a lattice model in one-dimension. The persistent exclusion process, where particles move at directions that change randomly at a low tumble rate $α$, is extended allowing sites to be occupied by more than one particle, with a maximum $n_\text{max}$ per site. Three phases are distinguished. For $n_\text{max}=1$ a gas of clusters form, with sizes distributed exponentially and no coarsening takes place. For $n_\text{max}\geq 3$ and small values of $α$, coarsening takes place and few large clusters appear, with a large fraction of the total number of particles in them. In the same range of $n_\text{max}$ but for larger values of $α$, a gas phase where a negligible fraction of particles takes part of clusters. Finally, $n_\text{max}=2$ corresponds to a crossover phase. The character of the transitions between phases is studied extending the model to allow $n_\text{max}$ to take real values and jumps to an occupied site are probabilistic. The transition from the gas of clusters to the coarsening phase is continuous and the mass of the large clusters grows continuously when varying the maximum occupancy, and the crossover found corresponds to values close to the transition. The second transition, from the coarsening to the gaseous phase can be either continuous or discontinuous depending on the parameters, with a critical point separating both cases.

description: One-dimensional organo-metal halide Perovskite (CH3NH3PbI3) nanorods whose diameter and length are dictated by the inner size of porous silicon nanotube templates have been grown, characterized and compared to bulk perovskites in the form of microwires. We have observed a structural phase transition for bulk perovskites, where the crystal structure changes from tetragonal to orthorhombic at about 150K, as opposed to small diameter one-dimensional perovskite nanorods, of the order of 30-70 nm in diameter, where the phase transition is inhibited and the dominant phase remains tetragonal. Two major experimental techniques, infrared absorption spectroscopy and photoluminescence, were utilized to probe the temperature dependence of the perovskite phases over the 4-300K temperature range. Yet, different characteristics of the phase transition were measured by the two spectroscopic methods and explained by the presence of small, tetragonal inclusions embedded in the orthorhombic phase. The inhibition of the phase transition is attributed to the large surface area of these one-dimensional perovskite nanorods, which gives rise to a large stress that, in turn, prevents the formation of the orthorhombic phase. The absence of phase transition enables the measurement of the tetragonal bandgap energy down to low temperatures.

description: We present a search for [CII] line and dust continuum emission from optical dropout galaxies at $z>6$ using ASPECS, our ALMA Spectroscopic Survey in the Hubble Ultra-Deep Field (UDF). Our observations, which cover the frequency range $212-272$ GHz, encompass approximately the range $6$4.5 $σ$, two of which correspond to blind detections with no optical counterparts. At this significance level, our statistical analysis shows that about 60\% of our candidates are expected to be spurious. For one of our blindly selected [CII] line candidates, we tentatively detect the CO(6-5) line in our parallel 3-mm line scan. None of the line candidates are individually detected in the 1.2 mm continuum. A stack of all [CII] candidates results in a tentative detection with $S_{1.2mm}=14\pm5μ$Jy. This implies a dust-obscured star formation rate (SFR) of $(3\pm1)$ M$_\odot$ yr$^{-1}$. We find that the two highest--SFR objects have candidate [CII] lines with luminosities that are consistent with the low-redshift $L_{\rm [CII]}$ vs. SFR relation. The other candidates have significantly higher [CII] luminosities than expected from their UV--based SFR. At the current sensitivity it is unclear whether the majority of these sources are intrinsically bright [CII] emitters, or spurious sources. If only one of our line candidates was real (a scenario greatly favored by our statistical analysis), we find a source density for [CII] emitters at $6

Psychosocial Factors, Sleep Disturbances, and Physical Activity in Patients After Cardiac Surgery
Creators: name: Lee, Sueyeon
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Cardiac surgery is one of the most effective tools for managing heart disease, the leading cause of death globally. After cardiac surgery, physical activity is key to improving patients’ quality of life and decreasing mortality, but more than 40% of post-surgical cardiac patients are physically inactive. Cardiac patients’ physical activity has been associated with anxiety, depression, self-efficacy, social support, and socioeconomic status (all psychosocial factors) and sleep disturbances. Consequently, greater understanding of the combined effects of psychosocial factors and sleep disturbances on physical activity will contribute to efforts to enhance patients’ physical activity after cardiac surgery. This research was conducted to examine relationships among psychosocial factors, sleep disturbances, and physical activity in patients who had undergone cardiac surgery. This dissertation first examines the influence of psychosocial factors and sleep disturbances on physical activity as well as the potential mediating role of sleep disturbances in these relationships. It then focuses on identifying the effects of daily sleep disturbances on daily physical activity. For these studies, 33 patients who had undergone cardiac surgery were recruited from a Chicago medical center and using an online recruitment site. Psychosocial factors, sleep disturbances, and physical activity were measured using an online survey, and sleep disturbances and physical activity were also measured using an ActiGraph for 7 days and nights. Regression analyses and structural equation modeling were applied to examine factors influencing physical activity and sleep disturbances’ mediating role between psychosocial factors and physical activity. In addition, mixed-effects model analyses were used to examine the effect of daily sleep disturbances on daily physical activity. Results showed that self-efficacy, sleep duration, sleep efficiency, and wake after sleep onset were predictors for physical activity after cardiac surgery; however, sleep disturbances played no mediating role between psychosocial factors and physical activity. Furthermore, daily sleep efficiency and number of awakenings were predictors for daily sedentary time. Overall, the results indicated that psychosocial factors and sleep disturbances should be assessed because of their impact on physical activity after cardiac surgery. In addition, patients’ daily sleep disturbances after cardiac surgery should be assessed because they can predict their next-day physical activity.

description: In many applications of absorbing structures it is important to understand their spatial response to incident fields, for example in thermal solar panels, bolometric imaging and controlling radiative heat transfer. In practice, the illuminating field often originates from thermal sources and is only spatially partially coherent when reaching the absorbing device. In this paper, we present a method to fully characterize the way a structure can absorb such partially coherent fields. The method is presented for any 3D material and accounts for the partial coherence and partial polarization of the incident light. This characterization can be achieved numerically using simulation results or experimentally using the Energy Absorption Interferometry (EAI) that has been described previously in the literature. The absorbing structure is characterized through a set of absorbing functions, onto which any partially coherent field can be projected. This set is compact for any structure of finite extent and the absorbing function discrete for periodic structures.

description: Diamond displays a large variety of luminescence centers which define its optical properties and can be either created or modified by irradiation. The main purpose of the present work is to study the radiation hardness of several of such centers in homoepitaxial single crystal CVD diamond by following the evolution of photoluminescence and ionoluminescence upon 2 MeV proton irradiation. Luminescence decays were observed with values of the fluence at half of the starting luminescence (F1/2) of the order of 1014 cm-2. The 3H center displayed a non monotonic behavior, with a growing behavior and a subsequent decay with a rather high F1/2 value (in the order of few 1016 cm-2), maintaining at the highest fluences an intensity significantly higher than the blue A-band. A simple model based on a double-exponential trend was defined to fit with satisfactory accuracy the evolution of the 3H center. Several PL centers (namely: 3H, TR12, 491 nm, 494 nm) exhibited clear correlations and anti-correlations in their fluence dependences, which were considered in the attempt to acquire some insight into their possible alternative attributions.

Assessing Major Safety Issues on Highway-Railroad Grade Crossings along the Addis Ababa Light Rail Transit
Creators: name: Berhanu, Gebreyohannes
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: Of the whole railway line, the major part where frequent accidents occur is highwayrailroad at grade crossings. The grade crossings along Addis Ababa Light Rail Transit (AA LRT) are located at areas with high pedestrian and vehicular traffic. Therefore safety levels at AALRT grade crossings will be major concern during operation. This research study assessed major safety issue at highway-railroad at grade crossings along AA LRT using accident rating models and highway-railroad level crossing engineering design guidelines and standards. The study identified the design and construction of highway-railroad level crossings along AALRT satisfied most of the design guidelines and criteria outlined by American Railway Engineering and Maintenance-Of-Way Association AREMA manual, Chinese standard GB50090, Federal Highway Association FHWA handbook and manual on uniform traffic control devices MUTCDS. Despite being compliant to the above design standards, level crossings at Tsehay Realestate roundabout, Salitemihiret roundabout, Adey Ababa and Sebategna junction found to have highest accident number. The geometry of the crossings and the traffic volume operating at these sections of AALRT are found to be major reasons for such high accident rate. For type 'F' traffic control system the smallest expected accident number per year is 0.28 at Kality side Meshualekiya roundabout level crossing. This result is higher than 0.075 a threshold value for the use of type 'G' traffic control system. Therefore the gates at the level crossings of AALRT should start operation. When gates are operational, accident frequencies from US DOT model are greater than 0.2 on the above hazardous level crossings. This 0.2 accident/year is the threshold value for grade separation. Therefore level crossings at Tsehay Realestate roundabout, Salitemihiret roundabout, Adey Ababa and Sebategna junction should be considered for grade separation if the cost of grade separation can be economically justified based on fully allocated life-cycle costs.

description: We study the decay mode of the $a_1(1260)$ into a $π^+$ in p-wave and the $f_0(980)$ that decays into $π^+ π^-$ in s-wave. The mechanisms proceeds via a triangular mechanism where the $a_1(1260)$ decays into $K^* \bar K$, the $K^*$ decays to an external $π^+$ and an internal $K$ that fuses with the $\bar K$ to produce the $f_0(980)$ resonance. The mechanism develops a singularity at a mass of the $a_1(1260)$ around 1420 MeV, producing a peak in the cross section of the $πp$ reaction, used to generate the mesonic final state, which provides a natural explanation of all the features observed in the COMPASS experiment, where a peak observed at this energy is tentatively associated to a new resonance called $a_1(1420)$. On the other hand, the triangular singularity studied here gives rise to a remarkable feature, where a peak is seen for a certain decay channel of a resonance at an energy about 200 MeV higher than its nominal mass.

description: We propose a method for sorting electrons by orbital angular momentum (OAM). Several methods now exist to prepare electron wavefunctions in OAM states, but no technique has been developed for efficient, parallel measurement of pure and mixed electron OAM states. The proposed technique draws inspiration from the recent demonstration of the sorting of OAM through modal transformation. We show that the same transformation can be performed with electrostatic electron optical elements. Specifically, we show that a charged needle and an array of electrodes perform the transformation and phase correction necessary to sort orbital angular momentum states. This device may enable the analysis of the spatial mode distribution of inelastically scattered electrons.

description: The gradient flow in QCD is treated perturbatively through next-to-next-to-leading order in the strong coupling constant. The evaluation of the relevant momentum and flow-time integrals is described, including various means of validation. For the vacuum expectation value of the action density, which turns out to be a useful quantity in lattice calculations, we find a very well-behaved perturbative series through NNLO. Quark mass effects are taken into account through NLO. The theoretical uncertainty due to renormalization scale variation is significantly reduced with respect to LO and NLO, as long as the flow time is smaller than about 0.1 fm.

description: Four exotic charmonium-like states, i.e. $X(4140)$, $X(4274)$, $X(4500)$, and $X(4700)$, have been observed very recently by LHCb Collaboration in the decay process $B^+\to J/ψϕK^+$ using the 3${\rm fb}^{-1}$ data of $p\bar p$ collision at $\sqrt s= 7$ and $8$ TeV. In this paper, we investigate systematically the properties of hidden charm tetraquark states. The hidden charm tetraquarks form an octet configuration and a singlet configuration according to flavor $SU(3)$ symmetry. Based on a diquark-antidiquark model, the hidden charm tetraquarks spectra are given. The previous XYZ exotic states altogether with the newly ones $X(4140)$, $X(4274)$, $X(4500)$, and $X(4700)$, can be well classified into certain representations. The spin-parities and masses of the XYZ are predicted, most of which are in agreement with the data. We particularly find that $Z_c(4430)$ may be treated as the first radial excitation of $Z_c(3900)$, while the $Y(1^{--})$ states can be obtained by the first orbital excitation of the $X/Z$ states. Besides, we calculate the decay widths of the hidden charm tetraquarks into two charmed mesons. This work gives a general tetraquark description for the XYZ states, which is helpful to uncover their inner structures.

Architecture of the Terminal Complex of Selenocysteine Synthesis in Humans.
Creators: name: Puppala, Anupama K
Publisher: name: University of Illinois at Chicago
Year: 2023

description: O-phosphoseryl-tRNASec selenium transferase (SepSecS) catalyzes the terminal step of selenocysteine (Sec) synthesis in archaea and eukaryotes. How the Sec synthetic machinery recognizes and discriminates tRNASec from the tRNA pool is essential to the integrity of the selenoproteome. Previously, we suggested that SepSecS adopts a competent conformation that is pre-ordered for catalysis. Herein, using high-resolution X-ray crystallography, we visualized tRNA-dependent conformational changes in human SepSecS that may be a prerequisite for achieving catalytic competency. We show that tRNASec binding organizes the active sites of the catalytic protomer, while stabilizing the N- and C-termini of the non-catalytic protomer. Our results suggest that a C-terminal helix regulates the overall architecture of the SepSecS•tRNASec complex by docking in the tRNA binding sites of the non-catalytic protomer, precluding tRNA binding. Binding of large anions to the catalytic groove may further optimize the catalytic site for substrate binding and catalysis. Our biochemical and mutational analyses demonstrate that productive SepSecS•tRNASec complex formation is enthalpically driven and primarily governed by electrostatic interactions between the acceptor-, TpsiC-, and variable arms of tRNASec and helices alpha1 and alpha14 of SepSecS. The detailed visualization of the tRNA-dependent activation of SepSecS provides a structural basis for a revised model of the terminal reaction of Sec formation in archaea and eukaryotes.

description: Acoustic wave devices provide a promising chip-scale platform for efficiently coupling radio frequency (RF) and optical fields. Here, we use an integrated piezo-optomechanical circuit platform that exploits both the piezoelectric and photoelastic coupling mechanisms to link 2.4 GHz RF waves to 194 THz (1550 nm) optical waves, through coupling to propagating and localized 2.4 GHz acoustic waves. We demonstrate acousto-optic modulation, resonant in both the optical and mechanical domains, in which waveforms encoded on the RF carrier are mapped to the optical field. We also show opto-acoustic modulation, in which the application of optical pulses gates the transmission of propagating acoustic waves. The time-domain characteristics of this system under both pulsed RF and pulsed optical excitation are considered in the context of the different physical pathways involved in driving the acoustic waves, and modeled through the coupled mode equations of cavity optomechanics.

description: We evaluate the partial decay widths for the semileptonic $Λ_b \to \bar ν_l l Λ_c(2595)$ and $Λ_b \to \bar ν_l l Λ_c(2625)$ decays from the perspective that these two $Λ^*_c$ resonances are dynamically generated from the $DN$ and $D^*N$ interaction with coupled channels. We find that the ratio of the rates obtained for these two reactions is compatible with present experimental data and is very sensitive to the $D^* N$ coupling, which becomes essential to obtain agreement with experiment. Together with the results obtained for the $Λ_b \to π^- Λ^*_c$ reactions, it gives strong support to the molecular picture of the two $Λ^*_c$ resonances and the important role of the $D^*N$ component neglected in prior studies of the $Λ_c(2595)$ from the molecular perspective.

description: We present results for time-dependent electron transport in a ballistic graphene field-effect transistor with an ac-driven gate. Nonlinear response to the ac drive is derived utilizing Floquet theory for scattering states in combination with Landauer-Büttiker theory for transport. We identify two regimes that can be useful for applications: (i) low and (ii) high doping of graphene under source and drain contacts, relative to the doping level in the graphene channel, which in an experiment can be varied by a back gate. In both regimes, inelastic scattering induced by the ac drive can excite quasi-bound states in the channel that leads to resonance promotion of higher order sidebands. Already for weak to intermediate ac drive strength, this leads to a substantial change in the direct current between source and drain. For strong ac drive with frequency $Ω$, we compute the higher harmonics of frequencies $nΩ$ ($n$ integer) in the source-drain conductance. In regime (ii), we show that particular harmonics (for instance $n=6$) can be selectively enhanced by tuning the doping level in the channel or by tuning the drive strength. We propose that the device operated in the weak-drive regime can be used to detect THz radiation, while in the strong-drive regime it can be used as a frequency multiplier.

Publisher: name: veterinary today

description: Bile acids (BAs) are amphiphilic sterol compounds that contain hydroxyl or carboxyl groups and alkyl groups, which are mainly synthesized from cholesterol by the liver. The bile acids (BAs) and their derivatives exert a variety of metabolic effects through complex and intertwined pathways, thus becoming the attractive target for metabolic syndrome treatment.To modulate the lipid homeostasis, the role of BAs, turn out to be paramount as it is essential for the absorption, transport of dietary lipids,regulation of metabolic enzymes and transporters that are essential for lipid modulation, flux, and excretion. Recently, the application of BAs as a dietary emulsifier on livestock production has raised increasing attention. Dietary supplementation with BAs is known to enhance growth performance, as well as improve lipid metabolism status by regulating the hepatic lipid metabolism-related gene expression and enzyme activities in animals

description: Strong magnetocrystalline anisotropy is a well-known property of uranium compounds. The almost isotropic ferromagnetism in $\mathrm{U_{4}Ru_{7}Ge_{6}}$ reported in this paper represents a striking exception. We present results of magnetization, AC susceptibility, thermal expansion, specific heat and electrical resistivity measurements performed on a $\mathrm{U_{4}Ru_{7}Ge_{6}}$ single crystal at various temperatures and magnetic fields and discuss them in conjunction with results of first-principles electronic-structure calculations. $\mathrm{U_{4}Ru_{7}Ge_{6}}$ behaves as an itinerant 5$f$-electron ferromagnet ($T_{\mathrm{C}}= 10.7 K$, $μ_{\mathrm{S}}= 0.85 μ_{\mathrm{B}}/f.u.$ at 1.9 K. The ground-state easy-magnetization direction is along the [111] axis of the cubic lattice. The anisotropy field $μ_{0}H_{\mathrm{a}}$ along the [001] direction is only of $\sim0.3 T$, which is at least 3 orders of magnitude smaller value than in other U ferromagnets. At $T_{r}=5.9 K$ the easy magnetization direction changes for [001] which holds at temperatures up to $T_{\mathrm{C}}$. The magnetoelastic interaction induces a rhombohedral (tetragonal) distortion of the paramagnetic cubic crystal lattice in case of the [111]([001]) easy-magnetization direction. The rhombohedral distortion is connected with two crystallographically inequivalent U sites. The ab initio calculated ground-state magnetic moment of $1.01 μ_{\mathrm{B}}/f.u.$ is oriented along [111]. The two crystallographically inequivalent U sites are a consequence of spin-orbit coupling of the U 5$f$-electrons. In the excited state which is only 0.9 meV above the ground state the moment points to the [001] direction in agreement with experiment.

description: This short note describes the long collaborative effort between Arizona and Kraków, showing some of the key strangeness signatures of quark-gluon plasma. It further presents an annotated catalog of foundational questions defining the research frontiers which I believe can be addressed in the foreseeable future in the context of relativistic heavy ion collision experiments. The list includes topics that are specific to the field, and ventures towards the known-to-be-unknown that may have a better chance with ions as compared to elementary interactions.

description: This article deals with the question of conflicts and continuity among the intellectual generations in Late Imperial Russia and in the period of post-revolutionary emigration through the works and private letters by Alexander Amfiteatrov, a journalist, writer and editor. The article focuses on the generation identity of the Russian intelligentsia as a reflection of the prominent social and political changes, a way to strengthen social solidarity and to declare new values of modernity. The generational discourse was formed by Russian literature and public thought, which created the ‘Generation of the Sixties’ as a pattern for the next generations of the Russian intelligentsia. Amfiteatrov identified himself with the ‘Generation of the Eighties’, describing this generation in different ways. The typical juxtaposition between the generation of the Sixties and the generation of the Eighties in the Russian society can be considered as a form of ‘generation gap’, a constant component of the generational consciousness, although the self-description of generations confirms the continuity rather than conflict between generations of the Russian intelligentsia. The idea of generation became one of the key elements to construct a social, political, and even national identity in the epoch of reforms and revolutions in Russia.

description: Rwanda is a landlocked country in east Africa. By vision 2050, Rwanda intends to become a middile income country with service based economy. Under this visoon, the country intends to increase GDP from 868.43 US$ per Cap to 12,476 US$ per Cap. The energy renewable share intends to reach 60% and remain at this level in following years. This study was made using OSeMOSYS tool learned under International Energy Agnecy capacity building program, specifically in “ICTP JOINT SUMMER SCHOOL FOR SUSTAINABLE DEVELOPMENT | 2023”. The study reflect to Rwanda energy system. The 3 scenarios were analysed BAU scenario, focus on the existing opportunities in technology and budget, Domestic focuses on energy security and promotion of domestic resources utulization (Hydro, solar and methan gas) and Renewable scenario, focus on imports, hydro utlization, solar and biomass. According to the SE4All Action Agenda and Rwanda Vision 2050, 60% of the generation mix should be from renewable sources by 2030 and beyond. The study results show less change in 2 base scenarios and clear change with adoption of renewable constraints. Here the best for costs management is renewable scenario, howver it create more emissions compared to other scenarios due to the promotion of biomass energy. This study was made for learning purposes and with reflection to the real stuation of the country. More scenarios will be created after these and data callibration will be improved in the near future.
Photon Emission Near Extreme Kerr Black Holes

description: Ongoing astronomical efforts extract physical properties of black holes from electromagnetic emissions in their near-vicinity. This requires finding the null geodesics which extend from the near-horizon region out to a distant observatory. In general these can only be found numerically. In this paper, for the interesting special case of extremally spinning Kerr black holes, we use an emergent near-horizon conformal symmetry to find near-superradiant geodesics analytically.

description: We study optical effects in quintessential Kerr black hole spacetimes corresponding to the limiting case of the equation-of-state parameter $ω_{q}=-1/3$ of the quintessence. In dependence on the dimensionless quintessential field parameter $c$, we determine the black hole silhouette and the spectral line profiles of Keplerian disks generated in this special quintessential Kerr geometry, representing an extension of the general modifications of the Kerr geometry introduced recently by Ghasemi-Nodehi and Bambi \cite{Gha-Bam:2016:EPJC:}. We demonstrate that due to the influence of the parameter $c$, the silhouette is almost homogeneously enlarged, and the spectral line profiles are redshifted with almost conserved shape.

Physical, chemical and sensorial characteristics of dried walnut of some varieties and promising variety candidates in Türkiye
Creators: name: Ozdemir, Yasin
Publisher: name: Journal of Applied Botany and Food Quality
Year: 2023

description: In this study some important physical, chemical and sensorial dried walnut characteristics of four varieties (‘Chandler’, ‘Fernor’, ’Yalova 3’ and ‘Şebin’) and five promising variety candidates (‘Giresun-7’, ‘İstanbul-2’, ‘144-84’, ‘Antalya-7’, ‘74-C’) were investigated. These findings were the first comprehensive report on the walnut properties of the above-mentioned candidates. ‘Antalya-7’ and ‘Giresun-7’ showed attractive fruit characteristics such as high whole kernel separation from shell and easy shell cracking. ‘Antalya-7’ attracts attention with fatty acids composition and appearance and taste scores. On the other hand, for ‘Giresun-7’, smooth shell surface, thin shell, high kernel ratio and high whole kernel separation from shell were determined as positive features. The polyunsaturated fatty acids content order of variety candidates was determined as 'Istanbul-2' > 'Antalya-7' > '144/84' > 'Giresun-7' > '74-C' (from high to low). The results of this study were used with agricultural project results for selection step of this breeding. The name of Giresun-7 was changed to 'Forest 77' and an application was made for variety registration. Its registration has been approved as a new variety by the Certification Center.

description: The goal of this work is to provide an elementary construction of the canonical basis $\mathbf B(w)$ in each quantum Schubert cell~$U_q(w)$ and to establish its invariance under modified Lusztig's symmetries. To that effect, we obtain a direct characterization of the upper global basis $\mathbf B^{up}$ in terms of a suitable bilinear form and show that $\mathbf B(w)$ is contained in $\mathbf B^{up}$ and its large part is preserved by modified Lusztig's symmetries.

description: We have used the Spitzer Space Telescope in February 2016 to obtain high cadence, high signal-to-noise, 17-hour duration light curves of Neptune at 3.6 and 4.5 $μ$m. The light curve duration was chosen to correspond to the rotation period of Neptune. Both light curves are slowly varying with time, with full amplitudes of 1.1 mag at 3.6 $μ$m and 0.6 mag at 4.5 $μ$m. We have also extracted sparsely sampled 18-hour light curves of Neptune at W1 (3.4 $μ$m) and W2 (4.6 $μ$m) from the WISE/NEOWISE archive at six epochs in 2010-2015. These light curves all show similar shapes and amplitudes compared to the Spitzer light curves but with considerable variation from epoch to epoch. These amplitudes are much larger than those observed with Kepler/K2 in the visible (amplitude $\sim$0.02 mag) or at 845 nm with the Hubble Space Telescope in 2015 and at 763 nm in 2016 (amplitude $\sim$ 0.2 mag). We interpret the Spitzer and WISE light curves as arising entirely from reflected solar photons, from higher levels in Neptune's atmosphere than for K2. Methane gas is the dominant opacity source in Neptune's atmosphere, and methane absorption bands are present in the HST 763, and 845 nm, WISE W1, and Spitzer 3.6 $μ$m filters.

Small-scale analysis of population genetics and abundance patterns of honeysuckle Lonicera periclymenum L. (Caprifoliaceae) in a North Sea island woodland system

description: Invasive alien plants are considered a major driving force of biodiversity loss and can deeply alter ecosystem functioning. However, invaders can also facilitate the distribution and establishment of native species, although this has been rarely documented in the literature. We observed an increase in population abundance of the liana Lonicera periclymenum L. (honeysuckle) on the north Frisian island of Amrum and hypothesized, that a surge in phorophyte availability due to the invasive neophyte Prunus serotina Ehrh. (black cherry) supported the colonization of new patches for this autochthonous liana species. Analysis of population genetics by inter-simple-sequence repeats polymerase chain reaction (ISSR-PCR) revealed high interpopulational differentiation. The genetic diversity within populations was low. The results indicated that barriers prevent small distance dispersal of seed and pollen. Further, additional results supported our hypothesis that honeysuckle may occasionally take advan-tage of the invasive neophyte black cherry.
