description: In this study, we investigated the performance of two 2D superconducting quantum interference filter (SQIF) arrays fabricated from YBCO thin films at a temperature of 77 K. Each array consisted of 6 Josephson junctions (JJs) in parallel and 167 in series. We conducted both experimental and theoretical analyses, measuring the arrays' voltage responses to an applied magnetic field and their voltage versus bias-current characteristics. To properly model the planar array layouts, our theoretical model used the stream function approach and also included the Johnson noise in the JJs. The model further divides the superconducting current density of the arrays into its Meissner current, circulating current, and bias current parts for practicality. Since the fabrication process of YBCO thin films cannot produce identical JJ critical currents, we assumed a log-normal distribution to model the JJ critical current disorder. Our model predictions, with a JJ critical current spread of 50%, agreed well with our experimental data. Using our model, we were able to study the dependence of the voltage modulation depth on critical current disorder and London penetration depth. We also analyzed the observed reflection asymmetries of the voltage versus magnetic field characteristics, which might provide insight into the degree of critical current disorder. Overall, our findings suggest that the use of YBCO thin films in SQIF arrays is promising, despite the critical current disorder inherent in their fabrication process. Our study highlights the importance of theoretical modeling in understanding the performance of superconducting devices and provides insights that could inform the design of future SQIF arrays.

description: The non linear charge transfer through a tunnel junction between two Luttinger systems is studied for repulsive, finite range interaction between electrons on the same, V_{11}, and on different,V_{12}, sides of the junction. Features of the Coulomb blockade effect are observed if V_{12}=0. We predict a novel interaction induced enhancement of the current if V_{12}>0. When V_{12}=V_{11}, the current is suppressed at small bias, but the ``charging energy'', obtained from the asymptotic behavior at high bias voltage, vanishes.

description: Cocoa cultivation currently faces scenarios that compromise the sustainability of the crop, both agronomically and commercially, a determining factor is climate change, which can provide conditions such as a higher incidence of pests and diseases, climatic disorders, among others. In Colombia, the productive chain has been growing in response to national policies, in this sense, during the year 2021 Colombia obtained a production of 69,040 tons, thus achieving a record production figure; Colombian cocoa has been recognized by the ICCO as fine flavor and aroma cocoa.
However, the high demand imposes the need to constantly face challenges in terms of material handling, selection of new genotypes with favorable attributes in terms of production, health, adaptation, evaluation of rootstock materials, evaluation of abiotic factors that limit the agricultural production and can generate negative effects on growth, productivity, and can cause damage to cell walls and membranes, stressing the root, restricting the absorption of water and nutrients, such as: drought, salinity, pH, high and low temperatures.
Given this background, the National Federation of Cocoa Growers, with resources from the National Cocoa Fund through the Research Program, has been working on the search for new rootstock materials tolerant to water deficit that help genetic improvement and contribute to the expansion and conservation of the genetic basis of cocoa. This is how the evaluation of materials began, where from an initial preliminary selection, 4 materials were prioritized, which demonstrated adaptation to abiotic stress conditions, water deficit.
Different patterns of water stress tolerance were identified between the evaluated rootstocks, however, FSV80 showed better tolerance levels to drought and a high adaptability to different water availability conditions. IMC67, FSA20, FSV80 showed the best adaptation and tolerance to water excess suggesting a potential use in soils exposed to water excess or flooding risks. Observed results could be used as an orientative resource for farmers, however, they must be correlated into the field and under different conditions like altitude, temperature, etc. The presented results represent an approach for adaptation and mitigation of the climate change effects, to ensure and Smart-climate agricultura, climatic resilience and food safety.

description: The volumetric representation of human interactions is one of the fundamental domains in the development of immersive media productions and telecommunication applications. Particularly in the context of the rapid advancement of Extended Reality (XR) applications, this volumetric data has proven to be an essential technology for future XR elaboration. In this work, we present a new multimodal database to help advance the development of immersive technologies. Our proposed database provides ethically compliant and diverse volumetric data, in particular 27 participants displaying posed facial expressions and subtle body movements while speaking, plus 11 participants wearing head-mounted displays (HMDs). The recording system consists of a volumetric capture (VoCap) studio, including 31 synchronized modules with 62 RGB cameras and 31 depth cameras. In addition to textured meshes, point clouds, and multi-view RGB-D data, we use one Lytro Illum camera for providing light field (LF) data simultaneously. Finally, we also provide an evaluation of our dataset employment with regard to the tasks of facial expression classification, HMDs removal, and point cloud reconstruction. The dataset can be helpful in the evaluation and performance testing of various XR algorithms, including but not limited to facial expression recognition and reconstruction, facial reenactment, and volumetric video. HEADSET and its all associated raw data and license agreement will be publicly available for research purposes.

description: I developed a new pure-python pipeline to reduce photometric and polarimetric data: ASTROPOP. It has been designed and optimized to work fully automated with the IAGPOL polarimeter of Pico dos Dias observatory (OPD, Brazil) and can reduce photometry and polarimetry data from other instruments, especially from SPARC4, a multi-channel polarimeter that has been developed for OPD. We present the results produced by this new code, and compare them with those obtained from PCCDPACK, a traditionally used IRAF package developed for IAGPOL. We also propose to use this code for automatic photometric reduction for the new ROBO40 telescope, also installed at OPD. ASTROPOP is fully open source and distributed under the BSD-3 clause license.

description: Experts in different domains rely increasingly on simulation models of complex processes to reach insights, make decisions, and plan future projects. These models are often used to study possible trade-offs, as experts try to optimise multiple conflicting objectives in a single investigation. Understanding all the model intricacies, however, is challenging for a single domain expert. We propose a simple approach to support multiple experts when exploring complex model results. First, we reduce the model exploration space, then present the results on a shared interactive surface, in the form of a scatterplot matrix and linked views. To explore how multiple experts analyse trade-offs using this setup, we carried out an observational study focusing on the link between expertise and insight generation during the analysis process. Our results reveal the different exploration strategies and multi-storyline approaches that domain experts adopt during trade-off analysis, and inform our recommendations for collaborative model exploration systems.

description: In an attempt to develop alternative process that meet the prescribed levels and green-technology criteria in gas-oil refining, N,N-methylpyrrolidone (NMP), dimethylformamide (DMF) mixed solvents under microwave-radiations (MW) were tested for the gas-oil desulfurization (EDS), denitrification (EDN) and dearomatization (EDA). In optimal conditions the gas-oil EDS-efficiency via MW can reach as high as 99.1% within 5 min at 500 W in three stages, which is much higher than EDS without MW (88.5% within 15 min) or than those of ionic liquids. The NMP/DMF/EG can be reused for multi-cycles before being regenerated by adsorption method. This study will provide useful information for future industrial application.

description: Neural networks have recently become good at engaging in dialog. However, current approaches are based solely on verbal text, lacking the richness of a real face-to-face conversation. We propose a neural conversation model that aims to read and generate facial gestures alongside with text. This allows our model to adapt its response based on the "mood" of the conversation. In particular, we introduce an RNN encoder-decoder that exploits the movement of facial muscles, as well as the verbal conversation. The decoder consists of two layers, where the lower layer aims at generating the verbal response and coarse facial expressions, while the second layer fills in the subtle gestures, making the generated output more smooth and natural. We train our neural network by having it "watch" 250 movies. We showcase our joint face-text model in generating more natural conversations through automatic metrics and a human study. We demonstrate an example application with a face-to-face chatting avatar.

"Knitting keeps my mind sharp and my fingers nimble": Knitters' information seeking and sharing during the COVID lockdown
Creators: name: , Mansourian

Year: 2021
Subjects: Serious leisure, hobbies, knitting, information seeking and sharing, user-generated content

description: This paper reports the initial results of an ongoing study about the information seeking and sharing patterns of knitters during the first year of the COVID pandemic. Knitting is a creative and inexpensive hobby that possesses all the six qualities of serious leisure, which are: perseverance and commitment, the potentiality to turn into a career, significant personal effort based on specific knowledge, durable personal and social benefits, unique ethos within a social world and developing new identities associated with the chosen activity (Stebbins, 1982). Almost forty years of research shows engagement in serious leisure activities (e.g. hobbies, amateurism, and volunteering) brings a range of physical, mental, and emotional benefits for the leisure pursuers. These benefits range from pure pleasure and a sense of fulfilment to self-actualisation and a sense of belonging (Heo et al., 2013; Riley, 2013; Kim et al., 2014; Corkhill et. al, 2014; Liu and Yu, 2015; Mansourian, 2021). However, serious leisure always happens in a context and several contextual elements can potentially boost or hinder leisure engagement. For example, during the COVID lockdown, group activities like outdoor hobbies faced various limitations. Nonetheless, indoor hobbies such as gardening and cooking increased in one way or another as people had more free time at home (Ling, 2020; Young, 2020). On the other hand, engagement in any hobbies or amateur activity, especially for beginners, requires access to some forms of information to learn the required knowledge and skills. Therefore, serious leisure is usually an information-rich context and the participants need to actively seek, search, organise, share and produce information about their hobbies or voluntary activities.

Taking the source to be an anti-de Sitter state specified by its Casimir invariants, we show how all the relevant features of the black hole are accounted for. The requirement that the source be a unitary representation leads to a discrete tower of states which provide a microscopic model for the black hole.

description: The balancing market for power is designed to account for the difference between predicted supply/demand of electricity and the realised supply/demand. However, increased electrification of society changes the consumption patterns, and increased production from renewable sources leads to larger un-predicted fluctuations in production, both effects potentially leading to increased balancing. We analyse public market data for the balancing market (manual Frequency Restoration Reserve) for Norway from 2016 to 2022 to investigate and document these effects. The data is newer than for similar analyses and the eight years of data is more than double the time span previously covered. The main findings are: a) The balancing volumes are dominated by hours of zero regulation but for non-zero hours, the balancing volumes are increasing during the eight-year period. b) The balancing prices are primarily correlated with day-ahead prices and secondary with balancing volumes. The latter correlation is found to be increasingly non-linear with time. c) The balancing volumes and the price difference between balancing price and day-ahead price are strongly correlated with the previous hour. d) The increasing share of wind power has not impacted the frequency of balancing, which has remained stable during the 8 years studied. However, the volumes and share of balancing power compared to overall production have increased, suggesting that the hours which are inherently difficult to predict remain the same. e) Market data alone cannot predict balancing volumes. If attempting, the auto-correlation becomes the main source of information.

 Etymology:
The epithet “boninense” is derived from the locality where the species was collected, the Bonin Islands, Japan.
 Type:
 Anijima Island, Tokyo, Japan, 2019, isolated from the roots of V. boninense (holotype, TNS-F-91409, dried culture on CMA; ex-type culture, NBRC 115392).
 Notes:
 Phylogenetic analysis based on ITS, LSU, MCM7, and RPB1 sequences can be used to distinguish between O. boninense and related species. Oidiodendron boninense show close phylogenetic relationship with O. ramosum (29 bp differences in ITS; 10 bp in LSU; 106 bp in MCM7; 60 bp in RPB1), O. setiferum (27 bp differences in ITS; 9 bp in LSU; 100 bp in MCM7; 69 bp in RPB1), O. muniellense (28 bp differences in ITS; 10 bp in LSU; 107 bp in MCM7; 61 bp in RPB1), and O. fuscum (29 bp differences in ITS; 10 bp in LSU; 107 bp in MCM7; 61 bp in RPB1). Oidiodendron boninense can be distinguished from O. ramosum, O. setiferum, and O. muniellense by the absence of conidiophores bearing melanized appendages at their apices and be done from O. fuscum by its longer asperulate conidiophores and spinulose conidia.

description: A solid density target irradiated by a high-intensity laser pulse can become relativistically transparent, which then allows it to sustain an extremely strong laser-driven longitudinal electron current. The current generates a filament with a slowly-varying MT-level azimuthal magnetic field that has been shown to prompt efficient emission of multi-MeV photons in the form of a collimated beam required for multiple applications. This work examines the feasibility of using an x-ray beam from the European XFEL for the detection of the magnetic field via the Faraday rotation. Post-processed 3D particle-in-cell simulations show that, even though the relativistic transparency dramatically reduces the rotation in a uniform target, the detrimental effect can be successfully reversed by employing a structured target containing a channel to achieve a rotation angle of $10^{-4}$ rad. The channel must be relativistically transparent with an electron density that is lower than the near-solid density in the bulk. The detection setup has been optimized by varying the channel radius and the focusing of the laser pulse driving the magnetic field. We predict that the Faraday rotation can produce $10^3$ photons with polarization orthogonal to the polarization of the incoming 100 fs long probe beam with $5 \times 10^{12}$ x-ray photons. Based on the calculated rotation angle, the polarization purity must be much better than $10^{-8}$ in order to detect the signal above the noise level.

description: Brain age prediction models have succeeded in predicting clinical outcomes in neurodegenerative diseases, but can struggle with tasks involving faster progressing diseases and low quality data. To enhance their performance, we employ a semi-supervised diffusion model, obtaining a 0.83(p<0.01) correlation between chronological and predicted age on low quality T1w MR images. This was competitive with state-of-the-art non-generative methods. Furthermore, the predictions produced by our model were significantly associated with survival length (r=0.24, p<0.05) in Amyotrophic Lateral Sclerosis. Thus, our approach demonstrates the value of diffusion-based architectures for the task of brain age prediction.

description: Value co-creation process as a mutual interaction between individuals is a key issue across the management network. Recently, studies have placed a special emphasis on people’s interaction in ord e r to ac co mplish val ue cocreation. Given that the process of experience exchange enables us to identify our resources in transactional processes and make collaboration to achieve common values, the purpose of this study was to identify factors affecting student value co-creation to institutionalize sustainability in agricultural and natural recourses universities. Statistical population of the research consisted of 2248 students of which 204 students were selected using stratified random sampling. The main research tool was a researcher-made questionnaire whose face and content validity was confirmed by a panel of experts and whose construct validity was confirmed by using explanatory factor analysis (KMO=0.752; P<0.01). The reliability was checked by calculating ordinal theta (θ≥ 0.89). Data was analyzed by SPSS20. Descriptive findings showed that student value co-creation level was moderate (43.060 %). The findings of exploratory factor analysis revealed that seven factors including teaching quality, support from top management, students’ social capital, confidence to faculty member, self-efficacy, proenvironmental values, and infrastructures of information and co mmunicatio n tec h n ol ogy (ICT) captured 77.74 percent of student value co-creation variance.

description: With the widening of the gap in water supply and demand in recent years and the schemes of the Ministry of Energy to restore and balance underground tables, the agricultural sector is projected to be under increasing pressure due to the rationing programs and the allocation of water resources to other sectors with higher economic efficiency in water use. We explored the economic impacts of non-pricing policy of limiting water supply and the policies of water pricing, taxing, and subsidization as per each m3 water use over or below the average gross requirement of the planting pattern on the components of the agricultural sector in Qazvin Province using the data and statistics for the 2013-2014 growing season and the expansion of positive mathematical programming model with the maximum entropy approach. The results showed that the non-pricing policy of 50% limitation of water supply would have the highest economic return per m3 water use. It is estimated to be $0.23. The highest reduction of chemical fertilizer use would be accomplished in the scenario of 50% limitation of water availability and the integrated scenario of 30% water availability limitation + 50% higher price for water. According to the comparison of employment per unit area vis-à-vis the reference year under different scenarios, the scenario of 50% limitation of water supply (20% increase per ha versus the reference year) would be the best for employment creation followed by the integrated scenario of 30% limitation of water availability. Since the non-pricing policy of limiting water availability would be more effective than the pricing policies in improving water use status and changing planting pattern, it is recommended to apply a combination of these policies in the studied region.

Non magnetic molecular Jahn-Teller Mott insulators

description: Narrow-band conductors may turn insulating and magnetic as a consequence of strong electron-electron correlation. In molecular conductors, the concomitance of a strong Jahn-Teller coupling may give rise to the alternative possibility of a non-magnetic insulator, with or without a static cooperative Jahn-Teller distortion. In the latter case the insulator has Mott-like properties, with an interesting interplay between electron-electron repulsion and the Jahn-Teller effect, which is dynamical. We study this kind of non-magnetic insulator in a very simple $E\otimes e$ Jahn-Teller model and we discuss its general properties in a more general context, also in connection with the insulating state of K_{4}C_{60} and Rb_{4}C_{60}.

Brako & Zarucchi (1993: 192); León & Monsalve (2006: 166).
Notes
This species was described from plants grown in the glasshouses of Kew Gardens, which J.D. Hooker stated in the protologue were collected in Peru by Pearce and given to Kew by Veitch Nurseries (Hooker 1868). The illustration and type specimen are however of a species closely allied to B. malabarica Lam., a species from southern India and Sri Lanka. Plant hunters from both Kew Gardens and Veitch Nurseries had collected in this area by this date, so it seems likely this is an Indian species whose providence was confused in either institution.

description: Afield experiment was conducted at Rice Research Station of Tonekabon, Iran, to determine the effect of seed inoculation with plant growth-promoting rhizobacteria on rice grain yield and yield components under different nitrogen (N) rates. The experimental design was a Randomized Complete Block with factorial arrangement and three replicates. Factors included seed inoculation with plant growth-promoting rhizobacteria [control (un-inoculated), seed inoculation with Azospirillum lipoferum, seed inoculation with Azotobacter chroococcum, and seed inoculation with a combination of A. lipoferum and A. chroococcum] and N rates (100%, 75%, and 50% of recommended nitrogen rates, i.e. 100, 75 and 50 kg N ha-1, respectively). Results showed that the highest grain yield (7875 kg ha-1) was recorded for plants inoculated with a combination of A. lipoferum and A. chroococcum, while the lowest one was recorded for un-inoculated control plants. Moreover, rice grain yield, panicle number per m2, grain number per panicle, and 1000-grain weight increased by 9%, 9%, 18%, and 6%, respectively, as N fertilizer rate increased from 50 to 100 kg ha-1. The highest grain yield (7875 kg ha-1) was obtained when N was applied at the rate of 75 kg ha-1 to seeds inoculated with a combination of A. lipoferum and A. chroococcum.

description: A six-night optical turbulence monitoring campaign has been carried at Cerro Paranal observatory in February and March, 2023 to facilitate the development and characterisation of two novel atmospheric site monitoring instruments - the ring-image next generation scintillation sensor (RINGSS) and 24-hour Shack Hartmann image motion monitor (24hSHIMM) in the context of providing optical turbulence monitoring support for upcoming 20-40m telescopes. Alongside these two instruments, the well-characterised Stereo-SCIDAR and 2016-MASS-DIMM were operated throughout the campaign to provide data for comparison. All instruments obtain estimates of optical turbulence profiles through statistical analysis of intensity and wavefront angle-of-arrival fluctuations from observations of stars. Contemporaneous measurements of the integrated turbulence parameters are compared and the ratios, bias, unbiased root mean square error and correlation of results from each instrument assessed. Strong agreement was observed in measurements of seeing, free atmosphere seeing and coherence time. Less correlation is seen for isoplanatic angle, although the median values agree well. Median turbulence parameters are further compared against long-term monitoring data from Paranal instruments. Profiles from the three small-telescope instruments are compared with the 100-layer profile from the stereo-SCIDAR. It is found that the RINGSS and SHIMM offer improved accuracy in characterisation of the vertical optical turbulence profile over the MASS-DIMM. Finally, the first results of continuous optical turbulence monitoring at Paranal are presented which show a strong diurnal variation and predictable trend in the seeing. A value of 2.65" is found for the median daytime seeing.

 Etymology:
 The specific epithet refers to the Japanese mycologist, former Prof.Dr.Seiji Tokumasu, who has contributed significantly to biodiversity research on microfungi, including the genus Oidiodendron in Japan.
 Type:
 Chichijima Island, Tokyo, Japan, 2019, isolated from the roots of V. boninense (holotype, TNS-F-91408, dried culture on PDA; ex-type culture, NBRC 115411).
 Notes:
 Oidiodendron tokumasui is phylogenetically closely related to O. maius (25 bp differences in ITS; 10 bp in LSU; 34 bp in MCM7; 37 bp in RPB1) but can be distinguished on the basis of the morphology of the conidiophores and the optimum temperature and pH. The conidiophores are shorter than those of O. maius. The optimum temperature and pH are higher than those for O. maius.

description: We model a particulate flow of constant velocity through confined geometries, ranging from a single channel to a bundle of $N_c$ identical coupled channels, under conditions of reversible blockage. Quantities of interest include the exiting particle flux (or throughput) and the probability that the bundle is open. For a constant entering flux, the bundle evolves through a transient regime to a steady state. We present analytic solutions for the stationary properties of a single channel with capacity $N\le 3$ and for a bundle of channels each of capacity $N = 1$. For larger values of $N$ and $N_c$, the system's steady state behavior is explored by numerical simulation. Depending on the deblocking time, the exiting flux either increases monotonically with intensity or displays a maximum at a finite intensity. For large $N$ we observe an abrupt change from a state with few blockages to one in which the bundle is permanently blocked and the exiting flux is due entirely to the release of blocked particles. We also compare the relative efficiency of coupled and uncoupled bundles. For $N=1$ the coupled system is always more efficient, but for $N>1$ the behavior is more complex.

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: A spatially-discrete sine-Gordon system with some novel features is described. There is a topological or Bogomol'nyi lower bound on the energy of a kink, and an explicit static kink which saturates this bound. There is no Peierls potential barrier, and consequently the motion of a kink is simpler, especially at low speeds. At higher speeds, it radiates and slows down.
