High-Resolution Electricity Spot Price Forecast for the Danish Power Market

Energy markets with a high penetration of renewables are more likely to be challenged by price variations or volatility, which is partly due to the stochastic nature of renewable energy. The Danish electricity market (DK1) is a great example of such a market, as 49% of the power production in DK1 is based on wind power, conclusively challenging the electricity spot price forecast for the Danish power market. The energy industry and academia have tried to find the best practices for spot price forecasting in Denmark, by introducing everything from linear models to sophisticated machine-learning approaches. This paper presents a linear model for price forecasting—based on electricity consumption, thermal power production, wind production and previous electricity prices—to estimate long-term electricity prices in electricity markets with a high wind penetration levels, to help utilities and asset owners to develop risk management strategies and for asset valuation.
Species-area relationships and the impact of deer-browse in the complex phytogeography of the Haida Gwaii archipelago (Queen Charlotte Islands), British Columbia

ABSTRACT We studied the biogeography of vascular plants on 10 islands in Laskeek Bay, Haida Gwaii (Queen Charlotte Islands), British Columbia. The islands varied in size from 4.5 to 395 ha and experienced a range of different browse pressures from introduced black-tailed deer (Odocoileus hemionus). We examined how island size interacted with browse pressure in determining the total species counts for individual islands. Numbers of plant species recorded increased with island area. The regression exponent for the log–log plot of species number on island area was 0.18, at the lower end of the range for such exponents. Many species absent from islands < 25 ha in area were characteristic of forest interiors, and consequently part of the increase in richness on larger islands probably was the result of increased forest interior area. Among the islands < 25 ha in area, the normal species–area and species–isolation relationships were reversed, with smaller, more isolated islands supporting more plant species than larger islands and, for a given area, more isolated islands supporting more species than less isolated ones. This reversal of the normal trend appears to be the result of deer browsing. Small, isolated islands were the only islands without deer and were richer, especially in wildflowers, than the larger, less isolated islands. On large islands, total species complement remained as predicted by area because the effect of deer was mitigated by the presence of deer-free refugia on cliffs and in isolated gullies. We conclude that deer are a major factor structuring the island plant communities and that continued protection of island habitats from introduced deer is essential to maintain the native flora of Haida Gwaii.
The impact of customer personality and online brand community engagement on intention to forward company and users generated content: palestinian banking industry a case

Abstract Personality five characteristics are playing crucial role on intention to forward Online Company Generated Content and user generated content mediated by online brand community engagement. This paper is applied on a case of banking industry in order to perceive a long run relationship between banks operating in Palestine and their customers. The total of 685 valid questionnaires were collected from online banking sector in Palestine, who is member of online brand community in Facebook. Moreover, the data were analysed and processed by structural equation model. The results reveal that personality traits (extraversion, conscientiousness, and openness) have positive influence on online brand community engagement. It also found that online brand community engagement plays vital role in inducing clients to forward CGC and UGC. Simultaneously, the results provide banks with a valuable implication on how banking industry can attract more customers in online brand community website and perceived trust of banks services and products.
Variants of Lactate Dehydrogenase Isozymes in Sera of Sockeye Salmon (Oncorhynchus nerka)

Three phenotypes of lactate dehydrogenase (LDH) isozymes were found in sera of sockeye salmon (Oncorhynchus nerka), presumably representing B′B′, B′B, and BB genotypes. No association was obvious between LDH phenotype of sera and sex or total body length.Of 1006 sera from Asian, Bristol Bay, and Gulf of Alaska stocks, 826 were B′B′ and 180 were B′B or BB. Of 591 sera from Washington and British Columbia stocks, 589 were B′B′ and 2 were B′B; both of the B-allele phenotypes were found in fish captured at the Skeena River in northern British Columbia. These findings suggested that LDH isozymes should be useful in studies on ocean distribution of sockeye salmon and in characterizing certain Asian and Alaskan sockeye salmon populations.
An Efficient Centroid Based Chinese Web

In this paper, we present an efficient centroid based Chinese web page classifier that has achieved satisfactory performance on real data and runs very fast in practical use. Except for its clear design, this classifier has some creative features: Chinese word segmentation and noise filtering technology in preprocessing module; combined 2 χ Statistics feature selection method; adaptive factors to improve categorization performance. Another advantage of this system is its optimized implementation. Finally we show performance results of experiments on a corpus from Peking University of China, and some discussions.
Differential roles of the Escherichia coli fumarases and fnr-dependent expression of fumarase B and aspartase

The physiological functions of the Escherichia coli fumarases A, B, and C (FUMA, B and C) were investigated using strains containing multicopy plasmids expressing each of the fum genes, and with single-copy fum-lacZ fusions. The results showed that FUMA is the critic acid cycle enzyme because it was strongly expressed under aerobic conditions but repressed by glucose and anaerobiosis. FUMB and FUMC were less susceptible to repression by glucose and anaerobiosis, and FUMB was identified as an anaerobic enzyme because its anaerobic expression was controlled by the anaerobic transcriptional activator, FNR. The expression of an aspA-lacZ fusion was also shown to be fnr-dependent.
FIELD TESTS OF A HIGHLY CONCENTRATED FORMULATION OF BACILLUS THURINGIENSIS AGAINST SPRUCE BUDWORM (CHORISTONEURA FUMIFERANA; LEPIDOPTERA: TORTRICIDAE)

Abstract During the summer of 1982, aerial experimental sprayings were carried out with a new formula of Bacillus thuringiensis named Futura®. This formula provided a treatment of the 20 × 109 IU of B. thuringiensis/ha required for suppression of spruce budworm (Choristoneura fumiferana), in a final volume of 2.5 L/ha. Results of spraying with Grumman AgCat and DC-4G aircraft are presented. These results were compared with those obtained with formulas of B. thuringiensis used in the past at 4.7 L/ha. Futura® caused 91.1 and 88.7% larval mortality and resulted in 86.6 and 75.1% foliage protection with the Grumman AgCat and DC-4G aircraft, respectively. Such results were equal to or better than those obtained with the formulas used earlier at 4.7 L/ha and confirm the feasibility of using B. thuringiensis operationally in an efficient and economical way. Résumé À l'été de 1982, une série de dispersions aériennes expérimentales fut réalisée avec une nouvelle préparation de Bacillus thuringiensis appelée Futura®. Cette préparation permet la dispersion des 20 × 109 UI de B. thuringiensis/hectare requises contre la tordeuse des bourgeons de l'épinette (Choristoneura fumiferana) dans un volume final de 2,5 L/ha. Les résultats des dipersions avec le monomoteur Grumman AgCat et le quadrimoteur DC-4G sont présentés. Ces résultats obtenus furent comparés à ceux de deux préparations de B. thuringiensis utilisées à date à raison de 4,7 L/ha. Ils indiquent que Futura provoque une mortalité larvaire de 91,1 et 88,7% et assure une protection du feuillage de 86,6 et 75,1% respectivement avec le Grumman AgCat et le DC-4G ce qui est au moins égal ou supérieur aux résultats obtenus avec les préparations utilisées précédemment à raison de 4,7 L/ha. La possibilité d'utilisation opérationnelle de B. thuringiensis de façon efficace et économique est donc confirmée.
Object Detection in Optical Remote Sensing Images Based on Residual Network

Conventional object detection algorithm based on deep learning only make use of deep feature which would become indiscriminative for small target in optical remote sensing images when the network deepens. In this paper, a multi-layer feature fusion method based on residual learning is proposed, which combine the shallow feature with deep feature to classify object comprehensively. First, a ResNet50 backbone network is constructed to extract feature from multiple layers. Then, the scales of feature at different layers are unified through RoI Pooling layer to screen region proposals and be classified through the SVM classifier. Comparative experiments are conducted on UCAS_AOD dataset released by UCAS and the result shows that our model achieved relatively good performance with 0.8802 and 0.9120 f1 score in car and airplane categories respectively.
Temporary migration of Palestinian students to the former USSR: motivations, conflicts and impact

ABSTRACT The article traces Palestinian Arab graduates in Israel, who acquired HE in the former USSR. The article clarifies the unique contribution of these studies to social, economic and political aspects of Palestinian Arab society in Israel. Qualitative methodology was employed, eliciting data from semi-structured interviews with 20 Palestinian Arab graduates, selected by ‘snowball’ method to represent two generations of students that migrated temporarily to the USSR for their studies. The findings indicate that the financial factor was a decisive motivator to study in the former USSR.As active communist party members, they received full scholarships for USSR universities. A ‘push’ factor was that the difficulty involved in gaining acceptance for prestigious disciplines in Israeli universities, free professions desiredby Palestinian students from Israel to free them from reliance on Israeli establishment employment. On graduation, the students returned to Israel, where they underwent a re-integration into a traditional Arab society that had hardly altered since they left. It is concluded that the former USSR supported and reinforced the economic, social and political fabric of Palestinian Arab society in Israel, training skilled academics and professionals who provide essential services and support for their society.
Effects of photoperiod and temperature on plasma gonadotropin and spermatogenesis in the rainbow trout Salmo gairdnerii Richardson

Summary. Two-year old male rainbow trout, Salmo gairdnerii, were exposed to the fol- lowing photoperiods at 80 or 16 °C from February 24 to June 19 : constant short photoperiod (8 L +16 D), constant long photoperiod (16 L + 8 D), and gradually decreasing photope- riod (from 16 L to 8 L). Control fish were exposed to natural photoperiod and temperature. Plasma and pituitary gonadotropin levels were determined by radioimmunoassay and correlated with spermatogenic response in testes. Control fish did not show advancement of spermatogenesis, whereas those exposed to decreasing photoperiod at 80 or 16 °C showed complete induction of spermatogenesis. While cooler temperature favoured production of spermatogonia and spermatocytes, the warmer temperature stimulated formation of spermatids and spermatozoa. On the other hand, in trout exposed to constant short or constant long photoperiod, spermatogenic response was weak at both temperatures. Plasma GtH levels increased in groups kept under decreasing photoperiod at both 8 ! C as well as 16 °C ; the magnitude of rise of GtH was greater at 16 oC than at 8 °C. GtH levels were significantly higher in trout exposed to gradually decreasing photoperiod than in animals kept under constant short or constant long photoperiod at 80 or 16 °C. The data suggest that the optimum photothermal combination for GtH release and induction of spermatogenesis in the rainbow trout is a gradually decreasing photoperiod (from 16 L to 8 L) at 16 ! C.
Ludlings: not all fun and games

Abstract Generations of children and adults alike have been using language games as a fun way to secretly communicate. These language games, also known as ludlings, are also used by criminals in furtherance of their crimes. In response, the FBI Laboratory in Quantico, Virginia assembled a team to study these systems and assist law enforcement agencies in the decryption of ludlings. This paper explains the most common English ludling systems encountered by the FBI.
Application of microsatellites from maize to teosinte and other relatives of maize

Teosinte comprises different Zea species (Zea mays, Zea diploperennis, Zea perennis, Zea luxurians) that can be crossed with cultivated maize (Z. mays ssp. mays). Nine microsatellites from maize were applied to different teosinte species in order to evaluate their usefulness in marker-based exploitation of these genetic resources. The same microsatellites were tested with rye, barley, and sorghum as potential molecular markers for these species. Almost all microsatellite × teosinte combinations yielded polymerase chain reaction (PCR) fragments in the range of cultivated maize. Using an F 2 population of a cross between maize inbred A188 and an individual of Zea mays ssp. mexicana, amplification products for maize and teosinte originated from the same genomic location for each of nine microsatellites investigated. PCR fragments of reduced intensity were generally obtained by applying maize microsatellites to rye, barley and sorghum. Polymorphisms among accessions within teosinte (sub)species occurred frequently. In contrast, no polymorphisms were obtained within rye, barley, and sorghum. Hence, application of maize microsatellites to teosinte for fingerprinting or marker-assisted introgression of genomic regions from teosinte into cultivated maize appears promising.
Relating a recruitment shift of Patagonian grenadier (Macruronus magellanicus Lönnberg) to large-scale environmental changes off Southern Chile

The SE Pacific stock of Patagonian grenadier (Macruronus magellanicus) showed evidence of an abrupt reduction in recruitment after 2000. This drop exceeded expectations from changes in the spawning stock biomass (SSB), indicating a change in the stock-recruitment relationship (S-R). We evaluated whether variability in recruitment could be explained by concurrent changes in three environmental indices: sea-surface temperature anomaly (SSTA); southern oscillation index (SOI); and latitudinal position of the west wind drift bifurcation (WWDL). Continuous and discrete effects of these indices were tested as covariates in linear log-log and non-linear Ricker's S-R models. Discrete effects represented regime shifts detected in SSTA (1998), SOI (1998) and WWDL (1995). While SSTA was the only continuous variable found to be significant, the discrete 1998 regime shift supported the most informative model. The best Ricker's model considered a discrete intercept change in the same year: 1998. Although a spurious correlation between SSTA and S-R changes is possible, SSTA may be reflecting major physical or biological changes relevant to M. magellanicus juveniles in the SE Pacific.
BIFURCATION PHENOMENA IN THE SHORT TAYLOR-COUETTE CAVITY WITH THE ASYMMETRIC END-WALLS AT LOW Re

The paper presents the results of the numerical investigations (DNS) of unsteady phenomena observed in the short Taylor-Couette configurations (=H/(R2-R1)=2.6-4.0) of different radii ratios η=R1/R2=0.25-0.6 with the asymmetric end-wall boundary conditions. The computations are performed at low Reynolds numbers i.e. Re=R1(R2-R1)/=100-200. In such configurations many interesting bifurcation phenomena occur: homoclinic, heteroclinic and doubling period. The paper is thought as complementary to Mullin, Blohm [1] where the analysis is limited to =0.5. The present DNS results confirm that for =0.5 the flow dynamics is organized by a pair of codimension-2 bifurcation points. The DNS study has allowed for the determination of the neutral curves in the 3D parameter space (Re, ) and the detailed analysis of the modulated rotating waves for different . The study has shown that the MRW behavior depends strongly on  and Re. These results are presented in the light of Lopez et al. [2] observations.
Analysis of ant foraging algorithms

We consider some models of ant foraging and recruitment behaviour that depend on each individual ant following a simple algorithm. Self-organisation enables the colony as a whole to establish a foraging strategy in the absence of any hierarchical control. In this paper we investigate how the effectiveness of such a foraging strategy depends on the persistence of the signals used by the individual ants and on the errors they make in following such signals. The use of inhibitory as well as excitatory signals is considered, and shown to be extremely effective in certain circumstances. This is interesting, as such signals have never been observed in real ant colonies. Such models are often investigated by simulation, but we approach them from the point of view of statistical mechanics. Looked at another way, which yields some insight, we approximate the stochastic process that models the system by a diffusion process with small diffusion parameter. This approach does not replace simulation, but supplements it. Its advantage is that it can elucidate the role of parameters more clearly and using much less computer time than simulation, but its disadvantage is that many simplifying assumptions must be made before the problem is amenable to analytic treatment.
Lack of Prosodic Focus in Chongqing Dialect and Possible Historical Sources

This study investigates Chongqing Dialect, a language largely used in Southwest China which is mutually intelligible to Beijing Mandarin speakers. Phonetic variations triggered by focus in Chongqing Dialect, especially in the form of post-focus compression (PFC), are investigated in terms of max F0, mean F0, duration and intensity. A follow-up perception test is also conducted. The production experiment shows that there are no significant changes from no focus condition to focus condition in the factors analysed, and no PFC is observed in Chongqing Dialect. The perception test shows a rather low identification rate at around 40%. The results of this study support the hypothesis that there is a typological divide within the Chinese languages, and the reason is explored by an analysis of the historical roots of Chongqing Dialect. As a representative of Southwest Mandarin, the lack of PFC in Chongqing Dialect suggests that many other Southwest Mandarin dialects also may not have PFC.
Long‐Term Field Fertilization Significantly Alters Community Structure of Ammonia‐Oxidizing Bacteria rather than Archaea in a Paddy Soil

Long-term field fertilization experiments may provide useful insight into the relative contributions of NH 3 –oxidizing bacteria (AOB) and NH 3 –oxidizing archaea (AOA) to soil nitrification. In this study, the abundance and composition of AOB and AOA were investigated in bulk soil from paddy field plots (4 by 5 m) that received no fertilization (CK), 180 kg urea N ha−1 yr −1 (NPK), or 180 kg urea N plus 4500 kg rice (Oryza sativa L.) straw ha −1 yr−1 (NPK/OM) since 1988 (each with three replicated plots). Our results clearly indicate that long-term fertilization (22 yr) significantly altered the community structure of AOB rather than AOA in the soil within fertilized plots compared with the CK plot. Quantitative polymerase chain reaction analysis of the amoA genes that encode the ammonia monooxygenase subunit A revealed that the AOB in the fertilized plots were 50 times more abundant than in the CK plot. Denaturing gradient gel electrophoresis fingerprinting of the amoA genes demonstrated a drastic shift in the AOB community structure, resulting in highly enriched AOB similar to Nitrosospira cluster 3 in the fertilized plots. In contrast, the population size and composition of the AOA community remained largely unchanged in all plots. Furthermore, a positive correlation was observed between the bacterial rather than archaeal amoA gene copy numbers and potential nitrification activity among the soils. The distinct responses of AOA and AOB to long-term field fertilization were probably related to the availability of NH 3 . Our results suggest that AOB might play major roles in the NH 3 oxidation that occurs in bulk soil under the in situ fertilized paddy field conditions tested in this study.
Oligocene Deformation of the Chuandian Terrane in the SE Margin of the Tibetan Plateau Related to the Extrusion of Indochina

Mechanisms driving the tectonic evolution of the southeast (SE) margin of Tibet include the Paleogene extrusion of the coherent Indochina lithospheric block and the continuous deformation caused by lower crustal flow since the middle Miocene. The timing and style of regional deformations are keys to determining the role of each mechanism. Fault‐bounded and fault‐controlled Cenozoic basins within the SE margin of Tibet record regional deformation, surface uplift, and variations in paleoclimate but often are poorly dated. New magnetostratigraphy and 40Ar/39Ar dating of volcanic ashes constrain precisely the timing of sedimentation within the Lühe Basin to between ~35 and 26.5 Ma. The basin is located in the Chuandian terrane along the Chuxiong fault, which lies ~70 km north of, and parallel to, the Ailao Shan‐Red River fault. The asymmetric syncline of the Lühe Basin suggests syncontractional sedimentation, and the basal age of the basin represents the initiation of the Chuxiong fault and crustal shortening at ~35 Ma. This is coincident with the onset of the Ailao Shan‐Red River fault and supports a kinematic link between them. Our study suggests that, like the Ailao Shan‐Red River fault, the Chuxiong fault is a Paleogene transpressional structure that developed during the extrusion and clockwise rotation of Indochina around the Eastern Himalayan Syntaxis, which caused the late Paleogene deformation and surface uplift of the Chuandian terrane and Indochina. Our revised chronostratigraphy of the Lühe Basin provides further evidence that many of the “Neogene” sedimentary basins in the SE margin of Tibet may be much older than previously thought.
Vida-de-prateleira de goiabas, cv. Sassaoka, minimamente processadas e armazenadas em diferentes embalagens

The objective of this work was to investigate the guava cv. Sassaoka, minimally processed and stored in two types of containers, for eight days. The experiment was conducted in the laboratory of Food Technology, Universidade Estadual Paulista "Julio de Mesquita Filho (Unesp), Campus de Ilha S - SP. Guava fruits cv. Sassaoka, were taken to the laboratory, processed and stored for 6 days at 8 o C and relative humidity of 80%. The treatments were: PET and polystyrene trays with plastic wrap (14 µm) in four seasons. Every two days of storage three samples were taken from each treatment for evaluation of the loss of mass, the pH, the soluble solids, the acidity, the vitamin C content and the visual appearance. The styrofoam packing (tray) with plastic wrap provided better preservation compared to the PET packaging, keeping the fruit in good condition for up to four days after processing. The PET has a tendency to accumulate water in the package, from the second day of storage, and was inadequate for this purpose. The vitamin C content and soluble solids were higher at the end of processing in PET packaging, as well as the pH and the acidity.
