Energy Efficient Scheduling Algorithms for Sweep Coverage in Mobile Sensor Networks

Nowadays, with the development of micro-electro-mechanical technologies, sweep coverage with mobile sensors is more and more popular in wireless sensor networks, which is also applied widely in other scenarios, such as message ferrying and data routing in ad-hoc networks. In order to reduce the sweep cycle and the number of mobile sensors, we propose the Distance-Sensitive-Route-Scheduling (DSRS) problem, which is to consider the effect of sensing range. We prove that DSRS is NP-hard, and consider three different scenarios: the single sensing-point case, the general case, and the extended case. In the single sensing-point case, we propose an approximation algorithm ROSE to schedule the routes of the mobile sensors efficiently. For the general case and the extended case, we present two other approximation algorithms G-ROSE and E-ROSE based on ROSE. We further characterize the non-locality property and design a distributed algorithm D-ROSE, coordinating sensors to meet the sweep requirements with best effort. Our algorithms are scalable to different sweep coverage problems, and according to the simulation results, they greatly outperform other existing algorithms up to 45 percent especially with a large sensing range.
Hatchability of Chicken Eggs as Affected by Dietary Phosphorus and Calcium

Abstract Two experiments with caged egg-type hens and one experiment with broiler breeder hens on litter floors were conducted to determine interactions between dietary calcium and phosphorus as related to hatchability and other production characteristics. Reductions in hatchability of eggs from caged layers caused by suboptimal levels of inorganic phosphorus were partially offset by elevation of the dietary calcium. When phosphorus in the diet of caged layers was supplied entirely from plant sources, elevation of dietary calcium resulted in decreased hatchability and egg production. Hatchability of fertile eggs from broiler breeder hens on litter floors was not significantly affected by dietary calcium levels of 2.25 to 3.50%, or by total phosphorus levels of . 31 to 1.42%. Egg production was improved by supplementation of the diet with inorganic phosphorus up to . 41% total phosphorus, but it was depressed by further supplementation. Egg specific gravity decreased with increased phosphorus levels and was significantly depressed by high dietary phosphorus (1.42%). Recycling of phosphorus by coprophagy may be a factor affecting dietary phosphorus requirements of hens in litter floor pens.
Environmental variability facilitates coexistence within an alcid community at sea

We examined coexistence at sea among 7 taxa of diving, wing-propelled seabirds (Alcidae) in the genera Aethia, Uria, Cepphus, and Fratercula. Species abundances were measured simultaneously with a sulte of environmental factors in the northern Benng Sea, Alaska, USA; data from 260 adjacent and non-adjacent sites occupied by alcids foraging offshore near breeding colonies were then subjected to principal component analysis (PCA). We used PCA to group redundant environmental descriptors, to identify orthogonal axes for constructing a multi-dimensional niche, and to differentiate species associations within niche dimensions from species associations among niche dimensions. Decomposition of the correlation matrix for 22 environmental and 7 taxonomic variables with PCA gave 14 components (10 environmental and 4 species interactions) that retained 90% of the original ava~lable variance. Alcid abundances (all species) were most strongly correlated with axes representing tidal stage, a time-area interaction (due to sampllng layout), water masses, and a temporal or intra-seasonal trend partially associated with weather changes. Axes representing tidal stage, 2 gradients in macro-habitat (Anadyr and Bering Shelf Water masses), the micro-habitat of the sea surface, and an air-sea interaction were most important for detecting differences among species within niche dimensions. Contrary to assumptions of competition, none of 4 compound variables describing pr~rnarily species-interactions gave strong evidence for negative associations between alcid taxa sharing similar body sizes and feeding requirements. This exploratory analysis supports the view that alcids may segregate along environmental gradients at sea. But in this community, segregation was unrelated to foraging distance from colonies, in part because foraging 'substrate' was highly variable in structure, location, and area1 extent. We contend that coexistence within this seabird group is facilitated via expanded niche dimensions created from a complex marine environment.
A microsatellite‐based method for genotyping diploid and triploid water frogs of the Rana esculenta hybrid complex

Rana esculenta is a hybrid between Rana lessonae (LL) and Rana ridibunda (RR), and hybrids may be diploid (LR) or triploid (LLR or LRR). Genotypes can be roughly determined from erythrocyte size and morphometry in adult frogs, but accurate genotyping requires more labourious methods. Here I demonstrate that both the L and R genomes have specific microsatellite alleles, and that genotype and ploidy can be accurately inferred from the quantitative ratio of PCR-amplified (polymerase chain reaction-amplified) genome-specific alleles. This method greatly facilitates genotyping in DNA studies of the R. esculenta complex and allows analysis of badly preserved samples and embryos.
No evidence to support an association of PER3 clock gene polymorphism with ADHD-related idiopathic chronic sleep onset insomnia

Abstract Idiopathic chronic sleep onset insomnia (SOI) in children with Attention‐Deficit/Hyperactivity Disorder (ADHD) shows typical characteristics of the delayed sleep phase syndrome and could, therefore, be considered a circadian rhythm sleep disorder. A variable number tandem repeat (VNTR) polymorphism of the clock gene PER3 is associated with the delayed sleep phase syndrome and, hence, may associate with ADHD-related chronic SOI as well. Here, we investigated an association between ADHD-related chronic SOI and the VNTR polymorphism of PER3 in 10 medication naïve children with rigorously diagnosed ADHD and SOI (ADHD-SOI), and in 10 normal controls. Actigraphic sleep onset and sleep duration and salivary dim light melatonin onset (DLMO) were evaluated in ADHD-SOI. The 4-repeat allele frequency was lower in ADHD-SOI (0.65) than in normal controls (0.75) (p = 0.73) with an odds ratio of 0.62 (CI 0.16 – 2.4). In ADHD-SOI, mean (±SD) DLMO (21:38 ± 0:50 h), sleep onset (22:17 ± 0:46 h), and sleep duration (9:26 ± 0:41 h) were not significantly related to the 4-repeat allele frequency. The present findings suggest no association between ADHD-related idiopathic chronic sleep onset insomnia and the PER3 VNTR polymorphism.
Plant Density-Dependent Variation in Marketable Yield, Fruit Biomass, and Marketable Fraction in Watermelon

An improved knowledge of effects of density of plants on yield of watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai] would help efforts to determine optimal planting density and to anticipate the economic impact of factors that reduce density. We conducted a series of experiments to determine plant density-dependent rates of change of marketable yield, fruit biomass, and marketable fraction in watermelon cultivar Sugar Baby. In single-row plots, at least 3.7 m apart, density varied from 0.4 to 4.1 plants m 2 (1000-9000 plants ha -1 ). Marketable yield per unit area increased at linear rates of 0.5 to 1.1 Mg ha -1 per thousand plants ha -1 because fruit biomass increased at linear rates of 1.1 to 3.2 Mg ha -1 per thousand plants ha -1 . The linear effect of plant density explained more than 90% of the increase in fruit biomass per unit area in most experiments. Density did not affect the fraction of fruit biomass that was of marketable quality. The linear rate of change in the marketable fraction did not exceed 3% per 1000 plants ha -1 on average in any experiment. Per plant, marketable yield and fruit biomass, respectively, decreased at curvilinear rates of 0.8 to 8.6 and 1.4 to 10.8 (kg plant -1 per thousand plants ha -1 ) (plants ha -1 ) 2 . These decreases were consistent with a constraint due to intraspecific competition. Our results support the hypothesis that efficiency of commercial production of watermelon could be increased by increasing planting densities.
Temperature Cycles as Zeitgeber for the Circadian Clock of Two Burrowing Rodents, the Normothermic Antelope Ground Squirrel and the Heterothermic Syrian Hamster

The circadian systems of two burrowing rodents, the normothermic diurnal antelope ground squirrel (Ammospermophilus leucurus) and the heterothermic nocturnal Syrian hamster (Mesocricetus auratus) were compared with respect to entrainment by temperature cycles. Both species were subjected to the same ambient temperature (Ta) cycles with amplitudes between 4 and 12oC at constant illuminations (100 and 0.05 lux in squirrels; 1.0 lux in hamsters). Wheel running activity was continuously measured. There was considerable interindividual variation in the daily pattern of wheel-running activity and in the ability to entrain to Ta cycles of the same amplitude in both species. The activity rhythms of about 33 to 67% of the animals of the two species entrained to Ta cycles with amplitudes of 6 to 12oC. One of six squirrels and one of nine hamsters even entrained to Ta cycles of 4oC. In the antelope ground squirrels, activity occurred predominantly in the cooler phase of the Ta cycle, whereas hamsters were mainly act.
Low-Complexity Dual-Vector-Based Predictive Control of Three-Phase PWM Rectifiers Without Duty-Cycle Optimization

The conventional model-predictive-based direct power control (MPDPC) of the three-phase full-bridge AC/DC converters chooses the best single voltage vector for the following control period, which results in variable switching frequency and power distortion, and thus a relatively higher sampling frequency is needed to achieve acceptable results. This paper proposes a simplified dual-vector-based predictive direct duty-cycle-control (SPDDC) with an additional zero vector implemented in contrast to the MPDPC. With the same best vector selection method, the proposed strategy has retained the control simplicity with just one more step added and much better control performance as well as a fixed switching frequency in comparison to the MPDPC. On the other hand, the duty-cycle optimization procedure is eliminated while the negative duration issue is essentially resolved compared with the conventional dual-vector-based model predictive duty-cycle-control (MPDCC). Comprehensive comparisons of various control methods by numerical simulation and experimental testing show that the SPDDC can achieve better steady state and dynamic performance than the MPDPC and simpler algorithms than the MPDCC.
EFFECT OF ROW SPACING ON SEED AND HAY PRODUCTION OF ELEVEN GRASS SPECIES UNDER A PEACE RIVER REGION MANAGEMENT SYSTEM

The effect of row spacing on seed and hay yields of 11 perennial grass species, including crested wheatgrass (Agropyron cristatum L.), intermediate wheatgrass (A. intermedium (Host.) Beauv. ), a northern biotype of bromegrass (Bromus inermis Leyss.), a southern biotype of bromegrass, Russian wildrye (Elymus junceus Fisch.), meadow fescue (Festuca pratensis Hudson), creeping red fescue (F. rubra var. genuina L.), chewings fescue (F. rubra var. commutata Gaud), reed canary grass (Phalaris arundinacea L.), a turf-type timothy (Phleum bertolonii DC (P. bulbosum auct.)) and hexaploid timothy (Phleum pratense L.), was studied under a system with limited inputs of fertilizer and no weed control. The width of the row spacings ranged from 16 to 104 cm where seed yields were measured and from 27 to 93 cm where hay yields were measured. The seed yield of all grasses was greater at a row spacing of 16 cm than at row spacings of 60 cm or more. Hay yields of all grasses, averaged over four production years, were also gr.
l2,p-Norm Based Discriminant Subspace Clustering Algorithm

Discriminative subspace clustering (DSC) combines Linear Discriminant Analysis (LDA) with clustering algorithm, such as K-means (KM), to form a single framework to perform dimension reduction and clustering simultaneously. It has been verified to be effective for high-dimensional data. However, most existing DSC algorithms rigidly use the Frobenius norm (F-norm) to define model that may not always suitable for the given data. In this paper, DSC is extended in the sense of <inline-formula> <tex-math notation="LaTeX">$l_{2, p}$ </tex-math></inline-formula>-norm, which is a general form of the F-norm, to obtain a family of DSC algorithms which provide more alternative models for practical applications. In order to achieve this goal. Firstly, an efficient algorithm for the <inline-formula> <tex-math notation="LaTeX">$l_{p}$ </tex-math></inline-formula>-norm based KM (KM<inline-formula> <tex-math notation="LaTeX">$_{\mathrm {p}}$ </tex-math></inline-formula>) clustering is proposed. Then, based on the equivalence of LDA and linear regression, a <inline-formula> <tex-math notation="LaTeX">$l_{\mathrm {2,}p}$ </tex-math></inline-formula>-norm based LDA (<inline-formula> <tex-math notation="LaTeX">$l_{\mathrm {2,}p}$ </tex-math></inline-formula>-LDA) is proposed, and an efficient Iteratively Reweighted Least Squares algorithm for <inline-formula> <tex-math notation="LaTeX">$l_{\mathrm {2,}p}$ </tex-math></inline-formula>-LDA is presented. Finally, KM<sub>p</sub> and <inline-formula> <tex-math notation="LaTeX">$l_{2, p}$ </tex-math></inline-formula>-LDA are combined into a single framework to form an efficient generalized DSC algorithm: <inline-formula> <tex-math notation="LaTeX">$l_{2,{p}}$ </tex-math></inline-formula>-norm based DSC clustering (<inline-formula> <tex-math notation="LaTeX">$l_{2,{p}}$ </tex-math></inline-formula>-DSC). In addition, the effects of the parameters on the proposed algorithm are analyzed, and based on the theory of robust statistics, a special case of <inline-formula> <tex-math notation="LaTeX">$l_{2,{p}}$ </tex-math></inline-formula>-DSC, which can show better robustness on the data sets with noise and outlier, is studied. Extensive experiments are performed to verify the effectiveness of our proposed algorithm.
Effect of two different grazing systems on the performance of beef cattle grazing on hilly rangeland conditions

To evaluate two different grazing systems, one with set stocking grazing and the other one with rotational grazing using electrical fencing system, for the performance of grazing beef cattle on hilly rangeland conditions with altitude of above 2000 m two grassland areas were chosen next to each other and an area of 10 ha was fenced with wires for RG. Biomass available for grazing was also monitored. A total of 60 Simmental beef cattle were assigned to the experimental units equally. The experiment lasted for 90 days. The daily live weight gains were higher in RG (P<0.05) with no difference in mean biomass dry matter and sward height. It was concluded that RG using electrical fencing system can substantially improve grazing performance of beef cattle on hilly rangeland conditions.
Enhanced Frame-Similarity Technique for Detection of Respiratory and Cardiac Rhythms in Auscultation Records

An enhanced algorithm for recognizing the rhythms associated with cardiac and respiratory activity in auscultation signals has been developed on the basis of previously proposed approaches. The essence of this technique is to evaluate the energy similarity of fragments of the original record at their superposition with a progressive time shift. To estimate the time evolution of signal frequency content, the Short-Time Fourier Transform is applied to records obtained by the developed portable one-channel digital auscultation complex. The free terms of the linear regression model for “instant” amplitude-frequency spectrum calculated in four information-significant octaves with central frequencies of 63, 125, 250, and 500 Hz are chosen for a measure of acoustic energy variation. The procedure of averaging of initial sample at one-second time intervals is used to segregate the cardiac and respiration periodicity into “fast” and “slow” channels. It is shown that search for minimums of the introduced distances depicting the similarity of compared fragments provides a reliable tool for detecting of life activity rhythms contained in the auscultation signal.
Heuristic Enhanced Evolutionary Algorithm for Community Microgrid Scheduling

Scheduling of community microgrids (CMGs) is an important and challenging optimization problem. Generally, the optimization is performed to schedule resources of CMGs at minimum cost. In recent years, a number of algorithms have been proposed to solve such problems. However, the performance of these algorithms is far from ideal due to the presence of different complex equality and inequality constraints in CMGs. Furthermore, most of the current works ignore energy storage (ES) degradation costs in the optimization model, which has a significant impact on the life of ES. This paper develops both single and bi-objective optimization models by considering the life of ES along with the operating cost for scheduling a CMG. An efficient heuristic-enhanced Differential Evolution (DE) approach is proposed to solve these models; by exploiting the structure of equality constraints, the proposed heuristic is able to generate feasible solutions quickly. The significance of the proposed heuristic is that it can generate a high-quality solution with a considerably lower computational effort. Numerical simulations were performed to evaluate the performance of the proposed method, and obtained results were compared with the state-of-the-art algorithm. The simulation results corroborate the efficacy of the proposed method.
Effects of five years of intensive trawling on a previously unexploited smelt stock

In the years 1989–1993, over 1000 metric tons of fish (392 kg ha−1) was removed by trawls from the Enonselka basin in Lake Vesijarvi in order to enhance the water quality. Roach (52%) and smelt (28%) were the most abundant species in the catches. In this study, the effects of the mass removal on the previously unexploited smelt stock was assessed. The total smelt catch was c. 282 metric tons. Due to the mass removal, the density of the stock collapsed from c. 46 000 fish ha−1 in 1989 to c. 14 000 fish ha−1 in 1993 (M=1.0). The biomass of the stock decreased from 75 kg ha−1 in 1989 to 12 kg ha−1 in 1993. The age group composition of the stock changed clearly towards the dominance of younger age groups. The male/female relationship in the samples changed from clear dominance of females to the dominance of males and the infection rate by the sporozoan parasite Glugea hertwigi declined. The growth rate of the smelt did not change considerably during the years of mass removal. The results suggest that in biomanipulated lakes several mechanisms may prevent the exploited stock from responding to the increased mortality.
Utilization of a Concurrent Query Form to Improve Clinical Documentation in a VA Facility for Patients With Stroke or TIA

Caring for stroke patients diagnosed with acute ischemic stroke (AIS) and transient ischemic attack (TIA) at Veterans Health Administration (VHA) acute care hospitals is a very complex process that centers on accurate documentation. Inaccurate or missing documentation leads to patient safety issues, lower quality care, and inaccurate Veteran Equitable Resource Allocation (VERA) classification for reimbursement. This pilot project’s 3 problems of interest include improving provider response to clinical queries about documentation, capturing national metrics collected by the VHA, and accurately representing veterans in VERA classification. Based on a review of the literature available on patient treatment file (PTF) accuracy and clinical documentation improvement, the researcher used a three-pronged intervention for data collection and management plan. The data were abstracted from 97 (N = 97) AIS and TIA patient treatment files from calendar years 2015 to 2019, then compared with prospective data collected for a period of 3 months, and analyzed for statistical and clinical significance. The results of this pilot project included an increase in provider response to queries, captured metrics, and VERA classification of veterans that satisfies clinical documentation integrity according to VHA directives.
A clinical study on the effect of the prebiotic inulin in the control of oral malodour

The aim of this clinical study was to evaluate the potential of an inulin mouth rinse to reduce the proportions of tongue bacteria associated with oral malodour. Thirteen panellists rinsed with either 10% sucrose or a 10% inulin mouth rinse twice daily for 21 days. Breath odour levels were assessed using a Halimeter® and organoleptic assessment, both before and after sucrose, inulin or water rinses. Tongue pH was registered and the tongue flora was cultured on media selective for total and obligate anaerobes, streptococci and inulin fermenters. There were no differences in baseline Halimeter® levels over the 21 day period, but a slight decrease in organoleptic scores was noted. A reduction in odour levels assessed by Halimeter® and organoleptically was observed immediately after rinsing. The effect was greater by the end of the 21 day regime. Microbial counts remained high, and no significant differences were observed, but there was a trend towards increased streptococcal counts by the end of the 21 day period. Tongue pH baseline levels were approximately neutral, but immediately after carbohydrate rinses a typical Stephan curve was observed. There is some indication that the use of twice-daily carbohydrate mouth rinses (sucrose or the prebiotic inulin) can reduce oral malodour by encouraging the growth of acidogenic bacteria and inhibiting the obligate anaerobes associated with malodour. Inulin is a less cariogenic substrate, and inulin mouth rinsing may provide a novel method for the control of oral malodour.
Cytogenetic studies in Callicebus personatus nigrifrons (Platyrrhini, Primates)

Abstract This is the first study on the karyotype of a representative of Callicebus from Brazilian Atlantic Forest, which are in the list of threatened species. C. p. nigrifrons has 2n=42, where there are 14 bi-armed and six acrocentric autosome pairs. The X chromosome is submetacentric and the Y is bi-armed and the smallest chromosome of the karyotype. This is a new diploid number for this genus. The sequential G/C-banding shows that the constitutive heterochromatin is located in the centromeric and pericentromeric regions of all the chromosomes, and in the distal part of the short arm of pairs 5, 6, 8, 10, 11, 13 and 14. The sequential G/Ag-NOR as well as fluorescent in situ hybridization showed that rDNA 18S+28S sequences are located in the distal region of the short arm of pair # 4. The chromosomal comparison between Callicebus personatus nigrifrons with the previously published, C. moloch, shows that the karyotype of C. personatus is very different from that of the representatives of the C. moloch group as well as of the other taxa of the genus Callicebus. These results support the classification of C. personatus taxa in a separate taxonomic group isolated from the other Callicebus groups.
