Traditional salient object detection models are divided into several classes based on low-level features and contrast between pixels. In this paper, we propose a model based on a multilevel deep pyramid (MLDP), which involves fusing multiple features on different levels. Firstly, the MLDP uses the original image as the input for a VGG16 model to extract high-level features and form an initial saliency map. Next, the MLDP further extracts high-level features to form a saliency map based on a deep pyramid. Then, the MLDP obtains the salient map fused with superpixels by extracting low-level features. After that, the MLDP applies background noise filtering to the saliency map fused with superpixels in order to filter out the interference of background noise and form a saliency map based on the foreground. Lastly, the MLDP combines the saliency map fused with the superpixels with the saliency map based on the foreground, which results in the final saliency map. The MLDP is not limited to low-level features while it fuses multiple features and achieves good results when extracting salient targets. As can be seen in our experiment section, the MLDP is better than the other 7 state-of-the-art models across three different public saliency datasets. Therefore, the MLDP has superiority and wide applicability in extraction of salient targets.

This study was designed to assess the suitability of using sweet potato leaf meal (SPLM) as a substitute for the complete or partial replacement of soya beans as protein source in fish feed formulation. One hundred and sixty Clarias gariepinus fingerlings were fed different levels of experimental diets containing 40% crudeprotein. Sweet potato leaf mealwas used at different levels of10% (Diet/Treatment 2 i.e. T2), 20% (T3) and 30% (T4), while 0% served as control (T1). Fingerlings were fed diet at 5% of their body weight for 42days. This study determined the growth, survival and the best inclusion rate of SPLM in the diet which was conducted in a plastic tank. All experimental diet were accepted by the Clarias gariepinus fingerlings without impairing growth. The highest mean weight gain (2.5+ 0.09g) was obtained in fish fed with 10% SPLM inclusion (T2), while the least (1.8+ 0.09g) was recorded in T4 i.e. 30% inclusion. Similar trend was obtained for length increase, protein efficiency and percentage survival. All fish were good in condition except those offered diet T4. The best SPLM inclusion level of the study was obtained in T2.

Cooperative Principles

Cooperative principles represent one of the three elements of cooperative identity. In their current form, they have existed since 1995, when they were adopted by the International Cooperative Alliance, and they represent a recommendation to cooperatives around the world on how to organize their business. Adherence to these recommendations in everyday business practice of cooperatives is extremely challenging. In fact, there is a consensus in the literature that deviation from cooperative principles is inevitable. The paper analyzes the experiences of the Republic of Serbia in the implementation of cooperative principles from time of the first cooperatives until today, with special emphasis on agricultural cooperatives. The aim of this paper is to examine the extent to which cooperative principles are respected in the business of cooperatives in Serbia, what factors led to deviations from these recommendations and what consequences this had on the success of these organizations. The paper presents a synergy of theoretical consideration of the problem and examination of experiences of agricultural cooperatives in Serbia in the implementation of cooperative principles. Conducted research indicate that during the development of cooperatives, different levels of deviations from cooperative principles in the practice of agricultural cooperatives were recorded, from very mild to extremely significant deviations that led to the suppression of true cooperative nature. Modern cooperative practice in Serbia is marked by a low level of knowledge of the elements of cooperative identity by the members and management of cooperatives, which further stipulates the posibility of their implementation in practice.

Semantic event detection is an active and interesting research topic in the field of video mining. The major challenge is the semantic gap between low-level features and high-level semantics. In this chapter, we will advance a new sports video mining framework where a hybrid generative-discriminative approach is used for event detection. Specifically, we propose a three-layer semantic space by which event detection is converted into two inter-related statistical inference procedures that involve semantic analysis at different levels. The first is to infer the mid-level semantic structures from the low-level visual features via generative models, which can serve as building blocks of high-level semantic analysis. The second is to detect high-level semantics from mid-level semantic structures using discriminative models, which are of direct interests to users. In this framework we can explicitly represent and detect semantics at different levels. The use of generative and discriminative approaches in two different stages is proved to be effective and appropriate for event detection in sports video. The experimental results from a set of American football video data demonstrate that the proposed framework offers promising results compared with traditional approaches.

AbstractLow-level states of consciousness are characterized by disruptions of brain activity that sustain arousal and awareness. Yet, how structural, dynamical, local and network brain properties interplay in the different levels of consciousness is unknown. Here, we study fMRI brain dynamics from patients that suffered brain injuries leading to a disorder of consciousness and from healthy subjects undergoing propofol-induced sedation. We show that pathological and pharmacological low-level states of consciousness display less recurrent, less connected and more segregated synchronization patterns than conscious state. We use whole-brain models built upon healthy and injured structural connectivity to interpret these dynamical effects. We found that low-level states of consciousness were associated with reduced network interactions, together with more homogeneous and more structurally constrained local dynamics. Notably, these changes lead the structural hub regions to lose their stability during low-level states of consciousness, thus attenuating the differences between hubs and non-hubs brain dynamics.

Lysine is the reference amino acid (AA) in the ideal AA ratios for chickens. Feed formulation based on digestible AA has been shown to increase weight gain and feed intake and improve body composition in broilers. Amino acid (AA) in most feed ingredients will not be totally digested, and knowledge of such efficiency is important in formulating diets and will be used to eliminate differences in absorption efficiencies due to feedstuff sources. This study was conducted to evaluate the growth performance and blood parameters of broilers fed various levels of DL (Digestible Lysine) supplemented in diets from day 1 to day 18.

Currently, dry mixes (CDM) play an important role in the development of the world market of building materials. The industry of construction and finishing materials in Russia is quite young: the first time the dry building mixes appeared on the Russian market in the late 1980s, the consumption structure of CDM in the domestic market the main share (70%) are in the adhesive and plasters. The use of other compositions, in particular mixtures for self – leveling floors, does not have significant volumes and often the reason for this is the lack of design solutions and the low level of qualification of specialists at different levels from workers to designers who do not own CDM technologies.

Abstract Most patients or donors undergoing leukapheresis (LP) for autologous or allogeneic PBSC transplantation requires multiple collections to achieve a sufficient CD34+ cell dose. LP is usually initiated when peripheral blood (PB) CD34+ reached a certain level, such as 20/μl. The aim of this retrospective analysis is to summarize our institutional experience of initiating LP at a low PB CD34+ cell level of 5/μl and investigate the merit of the practice. All patients or donors underwent LP (using Cobe Spectra or Baxter Amicus) processing 3 times the blood volume. A total of 170 LP procedures (118 autologous and 52 allogeneic) was performed in 74 adult patients or donors (> 40 kg) between Jan 2004 and May 2005. Autologous patients were mobilized with chemotherapy and G-CSF while allogeneic donors with G-CSF alone. A “good” LP product is defined as one having ≥ 1 x 106 CD34+ cells/kg so that a minimum dose of 3 x 106/kg can be achieved in 3 collections. Our result showed that each PBSC product contained 6.07 x 108 WBC/kg (median, range: 0.13–17.5) and 1.59 x 106 CD34+ cells/kg (0.14–24.9). Total CD34+ cells in PBSC products were correlated to PB CD34+ cell counts (r = 0.79, data not shown). As shown in Table 1, initiating LP at higher levels of PB CD34+ cell increased the proportion of good LP. Nevertheless, 76% of collections initiated at > 5 CD34+ cells/μl achieved good LP criterion. It is possible that the level of PB CD34+ cells was still increasing in many patients or donors after initiation of LP at the low level. However, some patients /donors still achieved minimim CD34+ cell dose when second LP day (Day 2) PB CD34+ cell level was lower than that of first LP day (Day 1) (Table 2). These patients /donors would likely NOT have been collected if higher levels of PB CD34+ cells were used as guideline for start of LP. Eleven patients /donors whose Day 2 CD34+ cell count was below that of Day 1 achieved minimum CD34+ cell dose when LP was initiated at < 20/μl. When LP was initiated at < 10/μl, four individuals achieved minimum dose. All 4 were autologous patients mobilized with chemotherapy and G-CSF (3 AML and 1 NHL). In conclusion, our results showed that initiating LP at low PB CD34+ cells can be helpful to some individuals. The guideline may be especially useful in those patients that can only be mobilized marginally.

The main goal of all territorial administration units, including municipalities, is to promote socioeconomic development. The implemented actions address a broad range of economic, social, spatial and environmental issues. Therefore, socioeconomic development is a complex and multi-dimensional concept that is difficult to evaluate in an unambiguous and objective manner. Statistical methods in object-based multidimensional modeling support such evaluations by considering numerous attributes/variables, which increases the efficiency of the analytical process. In this article, Hellwig’s development pattern method was applied to classify rural municipalities in Podkarpackie Voivodeship based on their socioeconomic development. Twenty-seven indicators were designed for the needs of the analysis with the use of Statistics Poland data for 2018. Based on the results, the municipalities were grouped into four classes with different levels of socioeconomic development. Class III was the largest group, and it was composed of 39 municipalities with a medium-low level of socioeconomic development. Class II was composed of a similar number of municipalities (38) with a medium-high level of socioeconomic development. The smallest groups were Class I containing 18 municipalities with a high level of socioeconomic development, and class IV containing 14 municipalities with a low level of development.
