description: A large number of direct imaging surveys for exoplanets have been performed in recent years, yielding the first directly imaged planets and providing constraints on the prevalence and distribution of wide planetary systems. However, like most of the radial velocity ones, these surveys generally focus on single stars, hence binaries and higher-order multiples have not been studied to the same level of scrutiny. This motivated the SPOTS (Search for Planets Orbiting Two Stars) survey, which is an ongoing direct imaging study of a large sample of close binaries, started with VLT/NACO and now continuing with VLT/SPHERE. To complement this survey, we have identified the close binary targets in 24 published direct imaging surveys. Here we present our statistical analysis of this combined body of data. We analysed a sample of 117 tight binary systems, using a combined Monte Carlo and Bayesian approach to derive the expected values of the frequency of companions, for different values of the companion's semi-major axis. Our analysis suggest that the frequency of sub-stellar companions in wide orbit is moderately low ($\lesssim $13% with a best value of 6% at 95% confidence level) and not significantly different between single stars and tight binaries. One implication of this result is that the very high frequency of circumbinary planets in wide orbits around post-common envelope binaries, implied by eclipse timing (up to 90% according to Zorotovic & Schreiber 2013), can not be uniquely due to planets formed before the common-envelope phase (first generation planets), supporting instead the second generation planet formation or a non-Keplerian origin of the timing variations.

description: Technologies for mmWave communication are at the forefront of investigations in both industry and academia, as the mmWave band offers the promise of orders of magnitude additional available bandwidths to what has already been allocated to cellular networks. The much larger number of antennas that can be supported in a small footprint at mmWave bands can be leveraged to harvest massive-MIMO type beamforming and spatial multiplexing gains. Similar to LTE systems, two prerequisites for harvesting these benefits are detecting users and acquiring user channel state information (CSI) in the training phase. However, due to the fact that mmWave channels encounter much harsher propagation and decorrelate much faster, the tasks of user detection and CSI acquisition are both imperative and much more challenging than in LTE bands. In this paper, we investigate the problem of fast user detection and CSI acquisition in the downlink of small cell mmWave networks. We assume TDD operation and channel-reciprocity based CSI acquisition. To achieve densification benefits we propose pilot designs and channel estimators that leverage a combination of aggressive pilot reuse with fast user detection at the base station and compressed sensing channel estimation. As our simulations show, the number of users that can be simultaneously served by the entire mmWave-band network with the proposed schemes increases substantially with respect to traditional compressed sensing based approaches with conventional pilot reuse.

description: L’objectif de ce papier est d’examiner l’effet non linéaire de l’émission des emprunts obligataires sur la croissance économique des pays de l’UEMOA au cours de la période 2000-2019. Plus spécifiquement il s’agit de déterminer le seuil d’emprunt obligataire à ne pas excéder afin que la politique budgétaire soit efficace pour créer et soutenir la croissance économique au sein de l’UEMOA. Pour atteindre l’objectif de cette étude, nous avons opté pour le modèle de régression de transition lisse en panel (PSTR) développé par González et al. (2005). Nous avons utilisé des données de panel trimestrielles couvrant les 08 pays de l’UEMOA de 2005 à 2019 Nos résultats montrent qu’il existe une relation non linéaire de l’effet des emprunts obligataires sur la croissance économiques dans la région. Une analyse approfondie suggère qu’une meilleure maitrise de la stabilité macroéconomique, une bonne gestion du stock de la dette extérieure et de dépenses gouvernementales et de l’efficacité du gouvernement permettrait d’améliorer l’effet de l’émission des emprunts obligataires sur la croissance économique des pays de l’UEMOA.

description: Recently, studies of brown dwarfs have demonstrated that they possess strong magnetic fields and have the potential to produce radio and optical auroral emissions powered by magnetospheric currents. This emission provides the only window on magnetic fields in the coolest brown dwarfs and identifying additional benchmark objects is key to constraining dynamo theory in this regime. To this end, we conducted a new red optical (6300 - 9700 Angstrom) survey with the Keck telescopes looking for H-alpha emission from a sample of late L dwarfs and T dwarfs. Our survey gathered optical spectra for 29 targets, 18 of which did not have previous optical spectra in the literature, greatly expanding the number of moderate resolution (R~2000) spectra available at these spectral types. Combining our sample with previous surveys, we confirm an H-alpha detection rate of 9.2 (+3.5/-2.1) % for L and T dwarfs in the optical spectral range of L4 - T8. This detection rate is consistent with the recently measured detection rate for auroral radio emission from Kao et al. (2016), suggesting that geometrical selection effects due to the beaming of the radio emission are small or absent. We also provide the first detection of H-alpha emission from 2MASS 0036+1821, previously notable as the only electron cyclotron maser radio source without a confirmed detection of H-alpha emission. Finally, we also establish optical standards for spectral types T3 and T4, filling in the previous gap between T2 and T5.

description: Nano TiO2 is usually used in DSSCS. Recently, a variety of mixed oxide semiconductors have been extensively studied as a new way to enhance performances of Nano TiO2. These materials could have higher performance even new properties. In this paper, two samples of Sc/TiO2 in different wt% (2 and 4) were prepared by wet impregnation method using HOMBIKAT as TiO2 precursor. The prepared materials were characterized by ICP, X-ray diffraction (XRD), Raman spectroscopy, FTIR, surface properties, SEM and HRTEM. A relatively low cost Organic dye (Rose Bengal) RB and photocounter electrode were used. Different factors affecting the performance of the cell such as the effect of counter electrode thickness, effect of Photosensitizer concentration, effect of photosensitizer pH, effect of active area for photoanode and effect of electrolyte concentration were studied. The electrical properties for SC/ TiO2 and TiO2 were investigated by measuring the current density–voltage (J–V) under illumination conditions. 4wt% Sc/TiO2 showed the highest electrical properties. The open circuit voltage (Voc), short circuit current density (Jsc) and energy conversion efficiency () were found to be 0.835V , 20.46 mA/cm2 and 9.38%, respectively for 4 wt % Sc/TiO2 sample.

description: We use rotational gravity darkening in the disk of \emph{Kepler} star KOI-2138 to show that the orbit of $2.1-R_\oplus$ transiting planet candidate KOI-2138.01 has a low projected spin-orbit alignment of $λ=1^\circ\pm13$. KOI-2138.01 is just the second super-Earth with a measured spin-orbit alignment after 55 Cancri e, and the first to be aligned. With a 23.55-day orbital period, KOI-2138.01 may represent the tip of a future iceberg of solar-system-like terrestrial planets having intermediate periods and low-inclination circular orbits.

description: We present results of 12CO(J=2-1) observations toward four massive star-forming galaxies at z~1.4 with the Nobeyama 45~m radio telescope. The galaxies are detected with Spitzer/MIPS in 24 um, Herschel/SPIRE in 250 um, and 350 um and they mostly reside in the main sequence. Their gas-phase metallicities derived with N2 method by using the Ha and [NII]6584 emission lines are near the solar value. CO lines are detected toward three galaxies. The molecular gas masses obtained are (9.6-35) x 10^{10} Msun by adopting the Galactic CO-to-H2 conversion factor and the CO(2-1)/CO(1-0) flux ratio of 3. The dust masses derived with the modified blackbody model (assuming the dust temperature of 35 K and the emissivity index of 1.5) are (2.4-5.4) x 10^{8} Msun. The resulting gas-to-dust ratios (not accounting for HI mass) at z~1.4 are 220-1450, which are several times larger than those in local star-forming galaxies. A dependence of the gas-to-dust ratio on the far-infrared luminosity density is not clearly seen.

description: Promising results with the CHA2DS2-VASc risk score (CVRS) have been reported for the prediction of contrast-induced nephropathy (CIN). The aim of this study is to consolidate all the data available and examine the association between elevated CVRS and the incidence of CIN in patients undergoing percutaneous coronary intervention (PCI). We systematically searched PubMed, Embase, and Scopus for abstracts and full-text articles from inception to May 2022. Studies were included if they evaluated the association between a high CVRS and the incidence of CIN in patients undergoing PCI. Data were integrated using the random-effects, generic inverse variance method of DerSimonian and Laird. Prospero registration: CRD42022334065. Seven studies from 2016 to 2021 with a total of 7,401 patients were included. In patients undergoing PCI, a high CVRS (≥2: Odds ratio [OR]:2.98, 95% confidence interval [95% CI] 2.25–3.94, p < .01, I2 = 1%, ≥3: OR 4.46, 95% CI 2.27–8.78, p < .01, I2=56% and ≥4: OR:2.75, 95% CI 1.76–4.30, p < .01, I2 = 11%) was significantly associated with an increase incidence for CIN. Subgroup analyses were done in patients with acute coronary syndrome, and association with CIN remained statistically significant (≥2: OR 2.93, 95% CI 2.11–4.07, p < .01, I2=22%and ≥4: OR:2.24, 95% CI 1.36–3.69, p < .01, I2 = 0%,). In patients undergoing PCI, an elevated CVRS is associated with an increased risk for CIN. More rigorous studies are needed to clarify this association and to identify strategies to reduce CIN.

description: In this study we evaluate the potential of using Gen5 (1.4 m2) KAI PECVD reactors, originally designed for production of thin film silicon modules, for manufacturing of high-efficiency silicon heterojunction (Si-HJ) solar cells. It is shown that Gen5 KAI PECVD reactors can provide an excellent uniformity of optical and electrical properties of hydrogenated amorphous silicon layers across entire surface of a 110130 cm2 wafer carrier. Surface passivation with low surface recombination velocity (< 4 cm/s) is achieved on n-type FZ c-Si wafers. Si-HJ solar cells, with an efficiency as high as 20.4%, are produced using commercial 6 inch n-type CZ c-Si wafers and Gen5 KAI PECVD reactors. The potential to reach the efficiency above 21% is also demonstrated.

description: A chalcopyrite Cu(In, Ga)Se2 (CIGS) solar cell was fabricated on a flexible stainless steel (SS) foil substrate with thickness of 0.1 mm. An organically modified silica-based sol-gel barrier layer was introduced to the SS foil to improve the SS surface flatness and block iron diffusion from the substrate into the CIGS absorber. Surface roughness of the substrate was reduced with the sol-gel layer. A remarkable reduction in iron diffusion to below 1015 cm−3 was achieved through the introduction of the sol-gel barrier layer. An alkali silicate thin glass layer was also introduced on the sol gel barrier layer as an alkali metal source. Favorable Na doping of 1019–1020 cm−3 into the CIGS absorber resulted in an improvement in the photovoltaic properties of the absorber. An efficiency of 17.9% was obtained with a short circuit current density of 34 mA/cm2, open circuit voltage of 0.7 V, and fill factor of 0.75.

description: The clinoptilolite natural zeolites (NZs) posses low herbicide adsorption capacity demanding acid-, alkali-, or salt chemical modifications that enhance its adsorption. However, this may affect the material structure and charge distribution. Alternatively, zeolites may be synthesized at a high cost and time-consuming process. Consequently, new methods, such as the hydrothermal method, for NZ modification needs to be studied. In this sense, a novel surface-modified zeolite (SMZ), using hexadecyltrimethylammonium bromide (CTAB), in acid media was produced by the hydrothermal method and applied for the adsorption of Atrazine (ATZ), Diuron (DIU) and 2,4-D. Commercial NZ and SMZ were characterized by SEM, XRD, TGA, FT-IR, AA spectroscopy, pHPZC, Zeta potential and N2-physisorption. The SMZ chosen for the adsorption experiments was the one with the highest modification yield and adsorption capacity obtained from a complete design of experiments (CTAB=0.74 ; D=12 Mesh; HCl=0.1 M; t=6 h and T=205 ºC). The adsorption experiments revealed that the SMZ adsorption capacity for the herbicide 2,4-D (qmax=9.02 mg/g) was greater than that obtained for ATZ (qmax=2.11 mg/g) and DIU (qmax=1.85 mg/g), which was explained by the presence of the hydroxyl group and by geometric characteristics of the 2,4-D. Adsorption models’ fitting showed that the adsorption of 2,4-D onto SMZ were best described by pseudo-second order kinetic (k2=0.005-0.006 g/mg.min; qe,exp=7.122-8.614 mg/g) and Langmuir isothermal model (KL=0.283-0.499 L/mg; qm=7.167-7.995 mg/g). These results indicate that the hydrothermal method is a viable alternative to enable the use of NZs for the adsorption of emerging contaminants from wastewater.

description: CdTe devices have reached a remarkable success in the market due to the robustness of the material
and the simplicity of producing stoichiometric absorbers. For many years one of the strong limitations of this material
was its high electron affinity that needs copper in the back contact degrading the cells. However a wide community
of researchers has investigated and partially solved this issue, but very little has been done on the effect of the front
contact on the degradation of the cells.
In this paper we analyze the effect of different TCOs on the stability of CdTe solar cells. Solar cell efficiencies show
similar values but with some differences in Jsc, mostly due to the effect on the transmission spectra. However most
interesting results come from the analysis of the capacitance-voltage and drive level capacitance profiling and from
the aging of the different devices. Results show a different distribution of the defects for the solar cells with ITO front
contact, compared to ITO/ZnO based devices. This difference is confirmed also by the aging results in open circuit,
CV-DLCP measurements suggests diffusion of impurities from the glass/ITO stack.

description: In this paper, we report the results of spectroscopic and photometric observations of the candidate evolved massive star MN48 disclosed via detection of a mid-infrared circular shell around it with the Spitzer Space Telescope. Follow-up optical spectroscopy of MN48 with the Southern African Large Telescope (SALT) carried out in 2011--2015 revealed significant changes in the spectrum of this star, which are typical of luminous blue variables (LBVs). The LBV status of MN48 was further supported by photometric monitoring which shows that in 2009--2011 this star has brightened by approx 0.9 and 1 mag in the V and I_c bands, respectively, then faded by approx 1.1 and 1.6 mag during the next four years, and apparently started to brighten again recently. The detected changes in the spectrum and brightness of MN48 make this star the 18th known Galactic bona fide LBV and increase the percentage of LBVs associated with circumstellar nebulae to more than 70 per cent. We discuss the possible birth place of MN48 and suggest that this star might have been ejected either from a putative star cluster embedded in the HII region IRAS 16455-4531 or the young massive star cluster Westerlund 1.

description: The bioflocculant producing bacterial strain – UKD24 was isolated from the domestic sewage treatment plant. The isolated strain was identified as Klebsiella pneumoniae by using 16S rRNA gene sequencing. The K. pneumoniae UKD24 showed remarkable flocculation rates when grown with the carbon sources namely glucose, sucrose and lactose, and many commercial nitrogen sources. Furthermore, the fish waste extract (FE) was used to enhance the productivity of the bioflocculant as a nitrogen supplement and it showed a significant level of flocculation rate similar to the commercial nitrogen sources. The Box–Behnken experiments were designed to predict the optimal conditions for bioflocculant production and it suggested that glucose – 3.247 g L−1, FE – 0.5 g L−1 and inoculum size – 1% are the suitable levels for bioflocculant production. The FTIR analysis of the bioflocculant showed the functional groups related to the polysaccharides and the EEM analysis showed the fluorescence components related to the proteins and humic acids. The biochemical composition of the bioflocculant was identified as polysaccharides (24.36 ± 1.5%) and protein (12.15 ± 0.2%). The tested optimum conditions of the bioflocculant to induce flocculation were tested in the kaolin wastewater and it showed that the optimum dosage of the flocculant was 5 mg L−1 and the pH range was broad as 5–10. The cation dependency tests revealed that the monovalent and divalent cations are highly suitable for flocculation while the trivalent cations showed moderate flocculation. The Cr(VI) removal efficiency of the bioflocculant showed that ∼35% of heavy metal is trapped into flocks during the flocculation.

description: Carbon redirection has become the desired option for sustainable and energy-efficient wastewater treatment due to its contribution to a circular economy. However, its impact on downstream processes such as nitrification and denitrification requires further investigation. This research characterizes the nitrogen removal performance, footprint, aeration mode, and microbial composition of a flow-through membrane aerated biofilm reactor (MABR) downstream of a chemically enhanced primary treatment (CEPT) carbon redirection unit. The batch and long-term studies demonstrated relatively higher nitrification rates than those reported using conventional primary treated wastewaters. The results indicated that reducing carbon in the liquid train positively impacted nitrification by achieving 87 ± 12% (1.4 ± 0.4 g/m2.d) ammonia removal with an effluent 2.5 ± 2.8 mg/L ammonia concentration at a short hydraulic retention time (HRT) of 2.5 h. Despite the lower (1.9 ± 1) soluble COD:N, up to 75 ± 25% (0.6 ± 0.4 g/m2.d) total nitrogen removal was achieved at 4 h HRT by implementing intermittent aeration. The batch tests using the developed biofilms showed nitrification (denitrification) capacity up to 11 ± 1.7 gNH4-N/m2.d (8.5 ± 0.5 gNO3-N/m2.d) and 2.7 ± 0.6 gNH4-N/m2.d (2 ± 0.3 gNO3-N/m2.d) corresponding to ammonia and nitrate concentrations ranging from 10–30 mg/L and 2–10 mg/L, respectively. Microbial analysis indicated that the nitrifiers such as Nitrosomonas and Nitrospira were the dominant species. The ammonia-oxidizing, nitrite-oxidizing, and denitrifying bacteria relative abundances were 10.3 ± 1.5%, 20.7 ± 1.7%, and 20.0 ± 2.8% under continuous aeration and 1.3 ± 0.07%, 1.8 ± 0.09%, and 40.5 ± 3.1% under intermittent aeration, supporting the observed ammonia and total nitrogen removal processes, respectively. Overall, the results demonstrated that MABR downstream of the CEPT behave differently; thus, design guides should be updated accordingly.

description: The XXL survey is the largest survey carried out by XMM-Newton. Covering an area of 50deg$^2$, the survey contains $\sim450$ galaxy clusters out to a redshift $\sim$2 and to an X-ray flux limit of $\sim5\times10^{-15}erg\,s^{-1}cm^{-2}$. This paper is part of the first release of XXL results focussed on the bright cluster sample. We investigate the scaling relation between weak-lensing mass and X-ray temperature for the brightest clusters in XXL. The scaling relation is used to estimate the mass of all 100 clusters in XXL-100-GC. Based on a subsample of 38 objects that lie within the intersection of the northern XXL field and the publicly available CFHTLenS catalog, we derive the $M_{WL}$ of each system with careful considerations of the systematics. The clusters lie at $0.1

description: Accurate measurements of power conversion efficiency are required to correctly assess the value of perovskite solar cell technology. However, two processes that typically occur in current research prototype cells, namely degradation and slow (timescales of seconds to hours) response to changing conditions mean that careful attention must be paid to performance measurements to avoid significant errors. We investigate the dependence of scan direction and dwell time for cells with an ITO|PEDOT:PSS|CH3PbI3–xClx|PCBM|Ag architecture and attempt to identify optimal scan parameters for reporting steady-state current-voltage curves. Our results demonstrate that the absence of hysteresis in current-voltage curves is not sufficient to ensure that the derived parameters reflect steady-state performance.

description: The Milky Way presents the too-big-to-fail (TBTF) problem that there are two observed satellite galaxies with maximum circular velocity larger than 55km/s, and others have velocity less than 25km/s, but the cold dark matter model predicts there should be more than 10 subhaloes with velocity larger than 25km/s. Those massive subhaloes with $25km/s

description: We consider a one-dimensional oscillatory medium with a coupling through a diffusive linear field. In the limit of fast diffusion this setup reduces to the classical Kuramoto–Battogtokh model. We demonstrate that for a finite diffusion stable chimera solitons, namely localized synchronous domain in an infinite asynchronous environment, are possible. The solitons are stable also for finite density of oscillators, but in this case they sway with a nearly constant speed. This finite-density-induced motility disappears in the continuum limit, as the velocity of the solitons is inverse proportional to the density. A long-wave instability of the homogeneous asynchronous state causes soliton turbulence, which appears as a sequence of soliton mergings and creations. As the instability of the asynchronous state becomes stronger, this turbulence develops into a spatio-temporal intermittency.

Do open star clusters evolve toward energy equipartition?

description: We investigate whether open clusters (OCs) tend to energy equipartition, by means of direct N-body simulations with a broken power-law mass function. We find that the simulated OCs become strongly mass segregated, but the local velocity dispersion does not depend on the stellar mass for most of the mass range: the curve of the velocity dispersion as a function of mass is nearly flat even after several half-mass relaxation times, regardless of the adopted stellar evolution recipes and Galactic tidal field model. This result holds both if we start from virialized King models and if we use clumpy sub-virial initial conditions. The velocity dispersion of the most massive stars and stellar remnants tends to be higher than the velocity dispersion of the lighter stars. This trend is particularly evident in simulations without stellar evolution. We interpret this result as a consequence of the strong mass segregation, which leads to Spitzer's instability. Stellar winds delay the onset of the instability. Our simulations strongly support the result that OCs do not attain equipartition, for a wide range of initial conditions.

description: Photo-current collection efficiency imaging is a powerful tool to obtain spatially resolved quantitative information about the local contribution to the output current of a solar cell. The photo-current collection efficiency is the probability that an additionally generated photo-current will be collected at the terminals. A measurement technique was already reported for silicon solar cells which uses differential photo-luminescence images with an applied bias for the measurement of the photo-current collection efficiency at a chosen working point. We applied the same technique to thin film solar cells and modules. The measurements were performed on 1 cm² large CIGS cells and 10 x 10 cm² CIGS mini-modules. At the module level, the series connection between the individual cells needs to be taken into account in the interpretation of the photo-current collection images. We show how the results can quantify the influence certain cells in a module have on the overall collected photo-current of the module.

description: The efficiency gap between Cu(In,Ga)Se2 (CIGS) thin film solar cells of laboratory scale and module size is still a crucial aspect that hampers the success of this technology. A homogeneous processing of the thin film layer stack is of great importance to achieve defect free modules. Imaging techniques such as dark lock-in thermography (D-LIT) are successfully applied to detect local defects whose power dissipation produce local hot spots (often referred to as shunts) of increased heat emission. It turns out that these defects can be classified by their voltage dependence to be either ohmic or diode-like. Furthermore, even if a defect produces a significant D-LIT signal, it is not necessarily harmful to the efficiency of the cell. We induced ohmic and diode-like defects into healthy solar cells to study their impact on the current-voltage characteristic. In order to investigate the physical origins of different defect types, we apply two-dimensional simulations studying three different mechanisms: a local metallic connection between front and back contact, a local increase of trap density, and a local lack of cadmium sulfide buffer coverage. The local current density and its voltage dependence are regarded as well as the impact on the solar cell performance. We found that a metallic short produces an ohmic shunt whereby areas of high trap density or a CdS gap form diode-like defects. The impact on the solar cell performance depends on the specific conditions assumed. For example, a relatively small local increase of the trap density could produce a current concentration that might be visible in D-LIT measurements without being harmful for the efficiency.

description: Both automatic program verification and program transformation are based on program analysis. In the past decade a number of approaches using various automatic general-purpose program transformation techniques (partial deduction, specialization, supercompilation) for verification of unreachability properties of computing systems were introduced and demonstrated. On the other hand, the semantics based unfold-fold program transformation methods pose themselves diverse kinds of reachability tasks and try to solve them, aiming at improving the semantics tree of the program being transformed. That means some general-purpose verification methods may be used for strengthening program transformation techniques. This paper considers the question how finite countermodels for safety verification method might be used in Turchin's supercompilation method. We extract a number of supercompilation sub-algorithms trying to solve reachability problems and demonstrate use of an external countermodel finder for solving some of the problems.

description: Midsummer is a manufacturer of turn-key lines for CIGS solar cells. Using processing technology from the optical disc industry, Midsummer has developed an all-sputtered CIGS solar cell process and a sputtering tool capable of making CIGS cells at a cycle time of 18 seconds. The CIGS cells are made on thin ferritic stainless steel substrates, making the cells suitable for building lightweight flexible modules. The size of the cells is 156x156 mm, with rounded corners, resulting in 225 cm2 total area. A total area efficiency of 14.25% has been achieved for a 225 cm2 all-sputtered Cd-free CIGS cell on a thin ferritic stainless steel substrate. The paper describes the CIGS cell process, presents the DUO sputtering tool and highlights some of the CIGS process developments made by the Midsummer CIGS R&D team.
