Asynchronous Neighbor Discovery on Duty-Cycled Mobile Devices: Models and Schedules

Neighbor discovery is a fundamental problem in wireless networks. In this paper, we study asynchronous neighbor discovery on duty-cycled mobile devices. Most existing studies develop integer schedules where time proceeds in discrete slots and a node is awake or asleep for an entire slot duration. We show that integer schedules can lead to significant waste of resources, and develop a generalized non-integer model, where time is continuous and a node may become awake or asleep at any point of time (subject to a few constraints) so that the resultant schedules can be significantly more efficient than integer schedules. In addition, we provide a reduction that transforms any schedule in the integer model to a corresponding schedule in the generalized non-integer model while reducing the discovery latency by up to a factor of two. Applying this reduction, an optimal schedule in the integer model becomes an optimal schedule in the non-integer model. We further demonstrate the practicality of non-integer schedules in a testbed, and compare the worst-case discovery latency of several existing schemes under both integer and non-integer models. Last, we establish a family of lower bounds for the best achievable latency guarantee. These lower bounds are applicable to both integer and non-integer models, covering both symmetric and asymmetric settings, and encompassing the existing lower bounds that are only for a subset of settings as special cases.
Pembentukan Konsep Keintiman Berdsarkan Social Information Processing Theory pada Komunitas Sehatmental.id

Kesehatan mental telah menjadi isu global di berbagai negara sehingga diperlukan penanganan yang serius terhadap isu ini. Di Indonesia sendiri, masyarakat yang mengalami gangguan mental semakin meningkat tajam. Sejalan dengan meningkatnya jumlah komunitas di media sosial yang menyuarakan pentingnya kesehatan mental, ada optimisme bahwa upaya kesehatan mental dapat dilakukan juga melalui media sosial. Namun, benarkah media sosial dapat membangun semangat volunteer (ingin ikut terlibat secara langsung) karena keintiman yang terjalin didalamnya? Berdasarkan uraian tersebut, penelitian ini dilakukan untuk mengetahui konsep keintiman yang terbentuk dalam gerakan sosial kesehatan mental berdasarkan social information processing theory. Penelitian ini menggunakan konsep keintiman dari teori social information processing oleh Joseph Walther. Penelitian ini menggunakan pendekatan kualitatif dengan metode studi kasus pada individu – individu di Komunitas Sehatmental.id. Pengumpulan data dilakukan dengan wawancara mendalam terhadap 7 informan dari Komunitas Sehatmental.id. Hasil penelitian ini menunjukkan bahwa keintiman tidak terjadi pada individu – individu di Komunitas Sehatmental.id. Hubungan yang terbentuk bersifat impersonal karena hanya berfokus pada peran masing – masing anggota di dalam komunitas dan kegiatan yang akan dilaksanakan. Hal ini berdampak pada anggota volunter yang sering berganti – ganti di dalam Komunitas Sehatmental.id. Kecepatan respon yang diberikan saat berinteraksi pun tidak membuat anggota komunitas merasa lebih dekat satu sama lain. Hasil penelitian menunjukkan penggunaan kata “kita” atau “kamu” dapat membuat followers merasa dilibatkan. Namun, interaksi di media sosial sering kali dirasa tidak cukup sehingga perlu dilakukan pertemuan tatap muka di antara anggota dengan pengurus.
Effect of Essential Oils and GRAS Compounds on Postharvest Disease Control in Mango (Mangifera indica L.cv Tom EJC)

Purpose : Mango (Mangifera indica L. cv. Tom EJC) has a high economic value due to its unique qualities. Postharvest diseases such as anthracnose cause considerable loss of fruits in the market. Applications of synthetic fungicides are the common practice for controlling postharvest diseases, which could lead to hazardous effects on health. Therefore, search for alternative measures for the control of anthracnose are in demand. Research Method : Different fungal species have been described as causative agents of above disease. To determine the causative agent, fungal isolations were done from symptomatic fruits and identified by morphological and molecular techniques. Sodium bicarbonate, and sodium metabisulphite were used as GRAS (Generally Recognized as Safe) compounds and clove, cinnamon and citronella oils were used as essential oils during in-vitro studies to evaluate their potential to control the pathogen. The mycelial inhibitory capacity of five concentrations (1µLplate-1- 5µLplate-1) of each essential oil was evaluated in-vitro disc volatilization method. Compounds with minimum inhibitory concentrations were selected for in-vivo studies. Essential oil treatments for mango comprised of fumigation and application of GRAS compounds by dipping 15 and 30 minute time intervals. Physiochemical properties (pH, titrable acidity and total soluble solid content) of treated and non-treated mango fruits were evaluated. Findings : The identified causative agent of anthracnose was Colletotrichum siamense. Sodium bicarbonate (80000ppm), sodium metabisulphite (1500ppm) showed 100% inhibition of radial mycelia growth against the pathogen through in-vitro poison food method.100% inhibition of radial mycelia growth was reported with clove and cinnamon oil at all the concentrations tested (1-5µLplate-1). The citronella oil showed the lowest inhibitory activity. 15 minute and 30 minute dipping in sodium bicarbonate and fumigation with clove oil and cinnamon oil treatments effectively controlled anthracnose disease in mango, in comparison to the recommended fungicide Chlorothalonil (3mL/L). Physiochemical properties of mango were not altered by any of the treatments in comparison to no-treated fruits. Originality / Value : These results suggest that Sodium bicarbonate, Clove oil and Cinnamon oil could be used as alternatives to control the anthracnose disease in mango.
Genetic Gains from 30 Years of Cassava Breeding in Nigeria for Storage Root Yield and Disease Resistance in Elite Cassava Genotypes

ABSTRACT Cassava (Manihot esculenta Crantz) is crucial for both food security and poverty alleviation in Sub-Saharan Africa (SSA). Cassava improvement for SSA started at the International Institute of Tropical Agriculture in 1970, and several improved lines with different characteristics have been developed to date. The primary focus of breeding work has been to increase root yield, early bulking, tolerance to biotic and abiotic stresses, and increased dry matter content. This paper represents a study of 112 varieties cloned and introduced between 1970 and 2000, and evaluated in 2003 and 2004 to quantify genetic gains in root yield and disease resistance. The genetic gain per year was 1.3% for fresh root yield, 1.2% for dry root yield, 0.65% for cassava mosaic disease resistance, 0.21% for cassava anthracnose disease resistance, and -0.03% for cassava bacterial blight disease resistance. Though there was no statistical significance in the net negative genetic gain in cassava bacterial blight resistance, it is essential that more emphasis be placed on improving this trait to enhance stability and productivity in African environments.
Does Expression of Grounded Affect in a Hexapod Robot Elicit More Prosocial Responses?

—We consider how non-humanoid robots can communicate their affective state via bodily forms of communication, and the extent to which this can inﬂuence human response. We propose a simple model of grounded affect and kinesic expression and outline two experiments (N=9 and N=180) in which participants were asked to watch expressive and non-expressive hexapod robots perform different ‘scenes’. Our pre-liminary ﬁndings suggest the expressive robot stimulated greater desire for interaction, and was more likely to be attributed with emotion. It also elicited more desire for prosocial behaviour.
In vitro germination of Nosema apis (Microspora: Nosematidae) spores and its effect on their αα-trehalose/D-glucose ratio

Abstract Nosema apis spore hatching was examined in different salt solutions. Best results were obtained in 0.5 M NaCl + 0.5 M NaHCO3 at pH 6. No differences could be detected between sodium and potassium salts. The differences in efficacy between monovalent anions were more obvios, and a rank order could be formed: Cl- > Br- > F- > I-. The carbohydrate content of ungerminated and germinated spores was measured by GC-MS analysis. Only a very small shift in the ratio αα-trehalose/ d -glucose was found. Scanning electron microscopy of extruded spores was done. No convincing images of released sporoplasms were obtained.
Prediction of Player Churn and Disengagement Based on User Activity Data of a Freemium Online Strategy Game

Churn describes customer defection from a service provider. This can be observed in online freemium games, where users can leave without further notice. Game companies are looking for methods to detect and predict churn to enable management reaction. The recorded data of games can be analyzed for this purpose. In this article, we conducted a case study based on data from the freemium game The Settlers Online. Churn detection was achieved by application of four different labeling approaches, based on common churn and disengagement definitions within the game analytics literature. In order to model predictive classifiers, features were computed from the raw game data. Eight different machine learning algorithms returning binary classifications were applied. The results were compared for all algorithms regarding all labeling approaches. Random forests with sliding windows were the best solution in our case, returning area under curve values higher than 0.99, thereby enabling prediction accuracies of 97% in our dataset. The results were confirmed by tests on an independent dataset and in our discussion, we offer guidance on the interplay of feature engineering, labeling approaches—in particular, disengagement—and machine learning algorithms for churn prediction. Our recommendations are valuable for game companies and academics, who pursue similar studies.
Effects of a Fern-Dwelling Ant Species, Crematogaster difformis, on the Ant Assemblages of Emergent Trees in a Bornean Tropical Rainforest

ABSTRACT This study examined the effects of a fern-dwelling ant species, Crematogaster difformis Smith (Formicidae, Hymenoptera), which defends territories in large areas of the crowns of emergent trees, on the composition and spatial distribution of other ant species on the trees in a Bornean tropical rainforest. We investigated the within-tree distribution of nest sites and foraging areas of individual ant colonies on emergent trees. The ant species composition on trees occupied by C. difformis was significantly different from that on conspecific trees without C. difformis. The species richness of ants inhabiting emergent trees, colony abundance of ants that nested and foraged in the crowns, and colony abundance of ants that nested on and in the ground but foraged in the crowns were all significantly lower on trees occupied by C. difformis than on conspecific trees without C. difformis. These results suggest that C. difformis suppresses the distribution of other ant species on emergent trees by excluding them from C. difformis territories and that a single ant species can affect the structure of the entire ant assemblage in the canopy of tropical rainforests.
Effectiveness of Glomus species in protecting white clover against nematode damage

Three species of arbuscular mycorrhizal (AM) fungi, Glomus aggregatum Schenck and Smith emend. Koske, Glomus intraradices Schenck and Smith, and Glomus mosseae (Nicol. and Gerd.) Gerdemann and Trappe, were evaluated for their effectiveness to suppress the plant parasitic nematode Meloidogyne incognita (Kofoid and White) Chitwood in white clover (Trifolium repens L.) in a greenhouse study. Forty 1-day-old seedlings not colonized or colonized to the same extent by the fungi were transplanted into a growth medium uninoculated or inoculated with 10 000 M. incognita eggs. After 40 days of further growth, root mass, shoot mass, extent of galling, number of nematodes and nematode eggs in roots, and extent of mycorrhizal colonization of roots were determined. Growth of white clover was significantly stimulated by mycorrhizal colonization, and nematodes caused the greatest damage when plants were not colonized by the fungi. The degree to which mycorrhizal fungi reduced nematode damage varied with the species of my.
Subducted Lithospheric Boundary Tomographically Imaged Beneath Arc‐Continent Collision in Eastern Indonesia

We use traveltimes from a temporary seismic deployment of 30 broadband seismometers and a national catalog of arrival times to construct a finite‐frequency teleseismic P‐wave tomographic model of the upper mantle beneath eastern Indonesia, where subduction of the Indo‐Australian plate beneath the Banda Arc transitions to arc‐continent collision. The change in tectonics is due to a change from oceanic to continental lithosphere in the lower plate as inferred from geological mapping and geophysical, geochemical, and geodetic measurements. At this inferred transition, we seismically image the subducted continent‐ocean boundary at upper mantle depths that links volcanism on Flores to amagmatic orogenesis on Timor. Our tomographic images reveal a relatively high‐velocity feature within the upper mantle, which we interpret as the subducted Indo‐Australian slab. The slab appears continuous yet deformed as a result of the change in buoyancy due to the composition of the incoming continental lithosphere. Accordingly, there is a difference in dip angle between the oceanic and continental sections of the slab albeit not a gap or discontinuity. We suggest the slab has deformed without tearing to accommodate structural and kinematic changes across the continent‐ocean boundary as the two sections of the slab diverge. These results suggest that deformation in tectonic collisions can be localized along a continent‐ocean boundary, even at depth. We propose that future slab tearing may develop where we observe slab deformation in our study region and that a similar process may take place in collisions generally.
The Sexual Mindfulness Project: An Initial Presentation of the Sexual and Relational Associations of Sexual Mindfulness

Abstract Little research has evaluated the associations of mindfulness training on couple romantic and sexual well-being and no research has examined the role of sexual mindfulness within an intervention. We introduced the Sexual Mindfulness Project (SMP) that addressed sexual relationships through daily mindfulness, sexual mindfulness (remaining aware and non-judgmental during sexual experiences), communication, and problem-solving skills which was taught in a structured intervention. We examined the effects of this program with committed couples (N = 5) who attended a two-session version of this project. We use mixed methods and examined themes from participant interviews and explored how sexual mindfulness in romantic and sexual relationships may prompt feelings of connection and intimacy. Qualitative results indicated improvement in individual, romantic, and sexual well-being. In addition, as appropriate, we integrate quantitative findings of change in sexual mindfulness and the other outcomes using retrospective pre-post design. We used a retrospective pre/post test to avoid reference frame bias, as sexual mindfulness is a skill that individuals may over-estimate on a pretest as participants know little about how to evaluate their sexual mindfulness. We found that the participants’ perception of the mechanism of change included their efforts to slow down, pay attention to their own sexual experience and/or feelings, communicate more effectively, and then address those feelings or thoughts with their partner in a non-judgmental, open, and accepting way.
Effect of maternal lysine supplementation on the performance of growing rabbits. Preliminary results

Abstract The experiment studied the effect of dietary lysine supplementation to rabbit does on the performance and on meat’s protein and lysine content of their offspring. Half of the does (n=43) fed control diet (C; Lys: 0.68%), while the other half a lysine supplemented diet (L; Lys: 0.80%) from 3 days before AI until weaning. After kindling, half of the litters of C does were put under C does, while the other half under L does. The same procedure was followed for offspring of L does. After weaning, rabbits fed the same diet (0.68% Lys). Does’ dietary treatment significantly affected the weaning weight, however, only lysine supplementation during suckling age had negative effect (340 vs 315g for C and L does, respectively; P<0.01). The kit’s milk intake, measured at 3rd and 7th day of age, nursed by L does was significantly lower. Other productive and carcass traits did not differ significantly.
Movement patterns of goliath grouper Epinephelus itajara around southeast Cuba: implications for conservation.

Goliath grouper Epinephelus itajara is the largest grouper in the western hemisphere. Recently, populations have experienced dramatic declines that have become a major cause of concern for scientists and conservationists. It is essential for conservationists and managers to understand the species’ movement patterns if marine protected areas are to be effectively designed. We present results of goliath grouper movements following conventional tagging within and adjacent to the Jardines de la Reina Archipelago, which includes the Caribbean’s largest marine reserve. Five individuals were tagged in 2001 and tracked until 2003, with 541 underwater resightings through summer 2002 at the tagging sites. No goliath grouper were resighted after July 2002 at Jardines de la Reina diving sites. In February 2002, 1 individual was caught 36 km northeast of the tagging site. In August 2002, a second tagged specimen was caught 77 km southeast of the tagging site, while in August 2003, 2 individuals were captured 168 km southeast of the tagging site, at a possible spawning aggregation site. All recaptures took place outside reserve boundaries. We assess these findings and their implications for goliath grouper conservation in Cuba.
BIOMASS DYNAMICS IN AMAZONIAN FOREST FRAGMENTS

Habitat fragmentation affects aboveground biomass in Amazonian forests, with potentially important implications for carbon storage and greenhouse gas emissions. We assessed the dynamics of aboveground-biomass stocks by combining long-term (10– 19 yr) data on mortality, damage, growth, and recruitment of large (≥10 cm diameter at breast height [dbh]) trees with measurements of nearly all other live and dead plant material (seedlings, saplings, small trees, palms, lianas, downed wood debris, snags, litter) in 50 1-ha plots in fragmented and continuous Amazonian forests. The key process altering biomass dynamics in fragmented forests is the chronically elevated mortality of large trees, which apparently results from microclimatic changes and increased wind turbulence near forest edges. This, in turn, accelerates the production of necromass and leads to significantly increased wood debris and litter on the forest floor. Near forest edges, frequent canopy disturbance increases the amount of light in the understory, resulting in accelerated tree recruitment, significantly higher biomass of small (5– 10 cm dbh) trees, and higher liana densities. Surprisingly, the estimated annual turnover of wood debris increases significantly near forest edges, suggesting that decomposition is occurring more rapidly in fragmented than continuous forests. These results reveal that habitat fragmentation fundamentally alters the distribution and dynamics of aboveground biomass in Amazonian forests. The rate of carbon cycling probably increases sharply, both because long-lived canopy and emergent trees decline in favor of shorter-lived successional trees and lianas, and because necromass production and turnover both appear to increase. Carbon storage in live vegetation also declines because small successional trees and lianas (which typically have low wood density) store substantially less carbon than do large, old-growth trees. Finally, the decline and rapid decay of live biomass in forest fragments may produce substantial atmospheric carbon emissions, above and beyond that resulting from deforestation per se.
Optimization Naive Bayes Algorithm Using Particle Swarm Optimization in the Classification of Breast Cancer

Methods of data mining classification are used in various fields of research. Naive Bayes is one of the most used algorithms of data mining classification, especially in the medical science because Naive Bayes is considered good method for the data concerned with a statistical diagnosis. Optimization of diagnosis results needs to be done in terms of various weaknesses, including data passing certain classes even though the data it is irrelevant or relevant so the need to be optimized by feature selection. Optimization was done using Particle Swarm Optimazation algorithm for feature selection in breast cancer classification using Naive Bayes. The Naive Bayes method is used for the classification of breast cancer, while the Particle Swarm Optimization Algorithm is used for the selection of irrelevant attribute features in order to obtain optimal diagnosis results. The results of the Naive Bayes method were 95.49% while after being optimized with the Particle Swarm Optimazation Algorithm the result was 98.19%.
Effect of Different Fat Sources and Vitamin E Isoforms/ Levels on Carcass Characteristics, Meat Quality, and Belly/Bacon Characteristics of Pigs Grown to Heavy Slaughter Weights (>150kg)

OF THESIS Effect of Different Fat Sources and Vitamin E Isoforms/ Levels on Carcass Characteristics, Meat Quality, and Belly/Bacon Characteristics of Pigs Grown to Heavy Slaughter Weights (>150kg) Two separate studies were conducted to evaluate the potential interaction of fat sources and vitamin E (VE) on heavy slaughter weights. In Study 1, a total of 64 individually-fed pigs (28.41 ± 0.83 kg) were randomly assigned to 8 dietary treatments in a 4×2 factorial arrangement. Fat treatments included cornstarch (CS), tallow (TW), corn oil (CO), and coconut-oil (CN). VE treatments were dietary alpha-tocopheryl-acetate (ATA) at 11 and 200 ppm. In Study 2, a total of 72 individually fed pigs (28.55 ± 1.16 kg) were randomly assigned to 12 dietary treatments in a 2 × 6 factorial arrangement. Fat treatments were TW and CO. VE treatments included four levels of ATA (11, 40, 100, and 200 ppm) and two levels of mixed tocopherols (primarily gamma-tocopherol (γ-T); 40 and 100 ppm). For Study 2, slaughter weight (P = 0.04) and pork sensory attributes such as tenderness (P < 0.01), juiciness (P < 0.01) and overall approval (P < 0.01) increased with increasing dietary ATA VE. Feeding γ-T at 40 ppm, resulted in a higher L* and hue as well as a lower a*, a/b, and chroma. Furthermore, feeding γ-T at 100 ppm resulted in a lower L* and hue (P < 0.05) as well as a higher a*, a/b, and chroma (P < 0.05). During extended shelf life measurements, TW tended to have a higher L* (P < 0.05) and b* (P < 0.05). γ-T VE chops exhibited less of an off-flavor (P = 0.05). Bellies from pigs fed higher saturated fat acids displayed a greater belly depth (P < 0.05), a larger belly angle (P < 0.05), and a lower bacon fat shatter score (P < 0.05). Overall, feeding a higher percentage of statured fatty acids leads to a more desirable pork belly and supplementing higher levels of γ-T could improve shelf life color and consumer sensory analysis.
