Predicting video popularity based on video covers and titles using a multimodal large-scale model and pipeline parallelism

In the era of traffic, controlling traffic is equivalent to mastering influence and economic benefits. At the video level, under the premise of the same video content, it is very important to study what kind of cover and title can be more attractive to people. Unlike most previous studies that focused on YouTube videos, our data came from Bilibilis videos. This paper tried to use two neural network models, ViT and Bert, combined with GPipe and backend fusion multimodal data fusion methods, to predict the possible click-through rate and popularity of a specific video based on its existing video cover and title. In the process, we switched to different visual and language models to complete the same training task, with the goal of comparing the impact of different models on the results. By adjusting the weight of two models, we finally achieved a good result of up to 62% accuracy.

Biodiversity response to rapid successive land cover conversions in human-dominated landscapes

Much of the world’s formerly “intact” land cover has been modified by humans with major impacts on biodiversity. Extensive areas of already modified land are now being subjected to yet further land cover conversions. Indeed, in many places, land cover and land use are changing repeatedly and frequently. Here, we use ecological theory to develop a new conceptual framework with associated postulates about how biodiversity could respond to repeated and rapid changes in land cover (over timespans of years to decades). Our framework focuses on five drivers: (1) conversion completeness, (2) persistence of biological, chemical, and physical legacies from previous land cover type to a new kind of cover, (3) number of previous land cover conversions, (4) time elapsed since land cover change, and (5) levels of contrast between the previous and new land cover. We predicted that biodiversity responses to repeated conversions in human-generated land cover would be a function of the main effects of these five drivers, as well as complex interactions among them (e.g. each new land cover type may act as a filter for species assemblages and interact in complex spatio-temporal ways with the previous land cover). Biodiversity responses may therefore be species- and land cover type specific, and not be readily predictable from insights provided by studies of single landscape conversions from an intact to a human-dominated ecosystem. Ignoring the impacts of successive land cover conversions on biodiversity could lead to increased biodiversity loss with each land cover conversion. Therefore, impact assessments are needed each time a new land cover conversion is proposed. Policies and management actions need to focus on the maintenance and/or restoration of remnant vegetation and other kinds of natural features (like large trees and wetlands) with each land cover conversion.

The sky is the basis of the most important cosmic phenomena, as it represents a flat area dependent on the corners of the earth by four pillars, and it forms the upper part of the universe as it is represented as a kind of cover that protects it, and in which the luminous bodies move in it: such as the sun, the moon, stars, clouds and planets. The ancient Egyptian tried from the beginning to get acquainted with the secrets of the surrounding universe, especially the world of the sky with all its components. The sky is responsible for the implementation mechanism of the cosmic system by determining the field that the sun, moon and stars cross daily. She represents the divine mother who is tender to all creatures, as his Lord embodied the sky in the form of a female animal in the form of a lady or the cow of the sky, either in the Greek and Roman eras, the earth gave birth to Gaya, what he saw in it, the star-studded dome, the sky Uranus, and the sky became the seat of the gods.

Millimeter-Wave Sparse Imaging for Concealed Objects Based on Sparse Range Migration Algorithm

To relieve the system cost in densely sampling when applying the millimeter-wave (MMW) synthetic aperture radar (SAR) technique for imaging applications, an MMW sparse imaging method is presented by the combination of the under-sampling scheme in space and the following sparse imaging algorithm. Different from the requirement on sub-wavelength sampling interval by Nyquist law, the system only needs to collect a random subset of spatial samples. To transform the spatial samples into wavenumber domain, a sparse range migration algorithm (SRMA) is proposed to realize MMW sparse imaging by embedding the matrix completion (MC) technique into classical RMA. In light of the relationship of Fourier transform between the scattering coefficients and the wavenumber-domain echo, the proposed algorithm utilizes the atomic norm minimization to fulfill the MC from the small set of wavenumber-domain entries to their full data matrix. The experiments are conducted by a wideband MMW transceiver mounted on a linear trajectory for imaging two specimens with different kinds of cover. Their clear imaging contrast of azimuth-range profiles is obtained through SRMA under different under-sampling conditions and RMA with fully sampled data, and verify the effectiveness of the proposed method.

Niveles y distribución geográfica de la cobertura sanitaria en España

Tomando como información la Encuesta Nacional de Salud de 1993, en este artículo se analizan los niveles de cobertura sanitaria de la población española, distinguiendo entre modalidades (públicas y privadas) y tipo de cobertura (total, exclusiva y solapamiento). Se identifican, además, los modelos geográficos que se perfilan en la distribución de las modalidades más extendidas. Niveles y distribución de cobertura sanitaria responden a los dos rasgos fimdamentales del sistema de salud español: la práctica universalización de la cobertura sanitaria pública, básicamente a través de la modalidad de Seguridad Social, y el carácter complementario de la cobertura privada, mediante los Seguros Médicos Privados.
 
 [fr] Dans cet article, basé sur les données de l'Enquête Nationale sur la Santé faite en 1993, on analyse les niveaux de l'assurance maladie de la population espagnole en faisant la différence entre les modalités (publiques et privées) et les types de couverture (totale, exclusive et multiple). En outre, on identifie les modèles géographiques qui se dessinent dans la distribution des modalités les plus développées. Les niveaux et la distribution de l'assurance maladie repondent à deux caractéristiques fondamentales du Système d'Assurance Maladie espagnol: l'une correspond à la presque généralisation de l'assurance maladie publique à travers la Sécurité Sociale et l'autre à l'Assurance Maladie des régimes privés comme éléments complémentaires du système.

Ecohydrological changes in semiarid ecosystems transformed from shrubland to buffelgrass savanna

AbstractIn arid and semiarid lands worldwide, vegetation cover is being transformed to savannas dominated by exotic grasses. However, the ecohydrological and biogeochemical changes associated with this process remain little understood. For more than 3 years, we studied soil moisture dynamics in natural semiarid shrubland patches and compared those with changes in an adjacent site that had been transformed to an exotic buffelgrass (Cenchrus ciliaris) savanna. We found that volumetric soil moisture was higher in patches with some kind of cover. For both tree and bare patches, volumetric soil moisture and plant‐available water in the 60‐ to 100‐cm depth interval were significantly lower in the savanna than in the natural site. In buffelgrass patches, volumetric soil moisture and plant‐available water were higher at almost all depths and in wet years and increased significantly during the summer monsoon season, suggesting rapid infiltration mechanisms under buffelgrass. During years with wet winters, these mechanisms also led to brief accumulations of water in the soil profile (0–200 cm). Such changes in soil profile water dynamics brought about adaptive responses in perennial plant species. The ability of species to change their patterns of soil water use in the profile may be an important mechanism enabling them to compete when novel tree–grass interactions are established by invasion of grasses. Our results provide new insights for understanding the changes caused by grass invasion in arid and semiarid lands, as well as how these changes may impact ecohydrological dynamics in global change scenarios.

The effect of biodegradable nonwovens in butterhead lettuce cultivation for early harvest

Abstract Field experiments using ‘melt-blown’ biodegradable nonwovens were carried out on the ‘Melodion’ butterhead lettuce (Lactuca sativa var. capitata L.) cultivar for early harvest. All biodegradable nonwovens were manufactured in the Institute of Biopolymers and Chemical Fibres and POLMATEX CENARO in Łódź, Poland. Lettuce seeds were sown into boxes in a greenhouse at the beginning of March, and transplants were planted into the field at the beginning of April. Biodegradable nonwovens - aromatic polyester IBWCH 75 g m-2, polybutylene succinate Bionolle 100 g m-2 and standard polypropylene PP Agro 20 g m-2 - were stretched over the lettuce in the field. The covers were kept on until 4-5 days before harvest. Plots without covers were defined as the control. Ascorbic acid, soluble sugar, dry matter, nitrates, chlorophyll a, chlorophyll b and carotenoid contents were recorded in the leaves. All biodegradable nonwovens showed a positive effect on yielding in comparison to the control in 2009. In the second year of the experiment, there were no significant differences between covers with regard to the yield. Dry matter and soluble sugar content in both years of the experiment was diversified. Nonwovens used as covers in 2009 significantly increased the content of nitrates in comparison to the control. In the second year, the highest level of nitrates was demonstrated in the control object. It is worth underlining that the maximum allowed limit of nitrate content in lettuce (4000 mg kg f.w.) was not exceed. The kind of cover had no significant effect on the level of chlorophyll a in 2009 or chlorophyll b and carotenoids in 2009 and 2010 in the lettuce

'Lost Property' at Wadi Qusayr 173: Evidence for the Transportation of Tabular Scrapers in the Jafr Basin, Southern Jordan

Wadi Qusayr 173 is an extramural, cache-like site that produced only a few dozen tabular scraper components. Interestingly, around half of these were placed in a group beside a natural lava rise. There was no evidence for associated structural remains, or even a pit or any kind of cover. This paper argues that the finds represent lost property originating with pastoral nomads making a round trip between flint quarries in the Jafr Basin and sedentary communities to the west. The discovery of property 'lost' in the process of transportation provides a glimpse into the realities of the system through which tabular scrapers were produced and distributed, and thus a key to exploring the social dynamics of the Levant in the Chalcolithic and the Early Bronze Ages.

Effect of Perforated Film And Polypropylene Nonwoven Covering On The Marketable Value of Early Potato Yield

Effect of Perforated Film And Polypropylene Nonwoven Covering On The Marketable Value of Early Potato Yield The effect of cover material (perforated polyethylene film, polypropylene nonwoven) and date of its removal (2 and 3 weeks after plant emergence) on the marketable value of the yield of early potato cultivar (Aksamitka, Cykada) was investigated. Potatoes were harvested 60 and 75 days after planting, in the second and third decade of June. Plant vegetation forcing by covering resulted in an increase in the marketable tuber yield (diameter >30 mm) and improved marketable value due to a reduced share of small tubers, with the diameter of 31-40 mm, especially at a very early date of potato harvest. In potato cultivation for very early crop, the cover material had a greater effect on the tuber yield and its marketable value than the length of plant covering period. Perforated film was a better kind of cover than polypropylene nonwoven, especially in the year with cold spring. At the delayed date of potato harvest the marketable tuber yield depended, to a higher degree on the date of cover removal. Higher yield was obtained when the cover was removed 2 weeks after plant emergence.

Spatial Distribution of Apodemus Flavicollis and A. Agrarius in a Forest Community Quercetum-Petraea on Mt. Avala (Serbia)

ABSTRACTSpatial distribution of Apodemus flavicollis and A. agrarius were studied in a forest community Quercetum-petraea at Avala mountain (Serbia). During this study (1996–1999), 381 individuals of A. flavicollis and 127 individuals of A. agrarius were marked. Our results suggest different exploitation of space within habitats. The areas most favored by A. flavicollis were those with a dense canopy of Quercus petraea. Individuals of A. agrarius inhabited the area with dense cover of Rubus hirtus. These associations with different kinds of cover indicate the spatial division of habitats shared by two studied species.

Distribution of Container-Inhabiting Aedes Larvae (Diptera: Culicidae) at a Dengue Focus in Thailand

A Thai village with dengue transmission was surveyed for Aedes aegypti (L.) and Ae. albopictus (Skuse) larvae at the end of the rainy season. All containers (1,819) in 186 households were surveyed, recording the presence of larvae, container type, level of water, kind of cover, and location. The number of positive containers was proportional to the total number of containers in a household. Standard water jars (approximately 200 liters) contributed 57% and small water jars (< 100 liters) contributed 16% of the total infested containers. Each of the other 10 container types contributed < or = 10% of the total infested containers and were not statistically different from each other. Containers inside houses were infested significantly more often than were those outdoors, those under elevated houses or roofs, or those in bathrooms. Unexpectedly, standard water jars located outdoors that were covered with commercial metal lids were infested significantly more often than were uncovered jars.

Fractal analysis of brownian trajectories in fluids

Fractal analysis of molecular brownian motion in liquids was carried out in two and three dimensions. It was observed that the trajectories are self-affine and can be characterized by a differential fractal dimension, which varies with the trajectory length. The analysis of the brownian motion by different kinds of coverings, and the comparison of this motion with diffusion-limited processes, allows us to deduce that the ensemble of all trajectories has a multifractal structure. Finally, the brownian motion in disordered media was studied. Significant differences were found depending on the euclidean dimension in which the motions were performed.

Geophysical exploration through geologic cover

The purpose of this report is to discuss some of the techniques that can be applied to the problem of geophysical exploration beneath various kinds of cover and overburden. A brief view of the electrical properties found in different geographic environments is included and the problem of exploring in areas of high resistivity cover and low resistivity cover is considered. It is shown that several techniques such as induced polarization, electromagnetic sounding, magnetotellurics and radio frequency interferometry have a particular application in areas of high resistivity cover. The problem of exploring in areas of low resistivity cover is much more difficult. It is to be hoped that the induced polarization technique can be used in these cases, but it requires a much improved understanding of the problems of electromagnetic coupling. It is also shown that the new techniques of data processing and filtering can help significantly in the problem of aeromagnetic interpretation in areas of volcanic cover.
