Compact Uni-Planar Monopole Antenna for 2.4/5 GHz WLAN Operation for Laptop Applications

For achieving 2.4/5 GHz (2400~2484/5150~5350/5725~5825 MHz) WLAN (Wireless Local Area Network) operation, the shorted T-shaped monopole antenna or planar inverted-F antenna (PIFA) has been widely applied in the laptop computer [1]-[10]. These antennas generally comprise two directly-driven metal strips of about one-quarter wavelength at 2.45 and 5.5 GHz, and they usually show a total length of larger than 30 mm. Recently, in order to accommodate more antennas in the limited space in the laptop computer for other new communication systems, there are great demands in size reduction for the internal 2.4/5 GHz WLAN antennas. For this purpose, we present here a new uni-planar dual-band monopole antenna having a compact area of 6 × 20 mm and capable of generating two wide bands for 2.4/5 GHz WLAN operation. The proposed antenna has a simple uni-planar structure and is very suitable to be printed on an inexpensive FR4 substrate, making it easy to fabricate with a low cost. The antenna comprises a driven inverted-L strip and a coupled strip to be short-circuited to the supporting metal plate of the display of the laptop computer. With the selection of a proper coupling gap between the driven and coupled strips, good excitation of two operating bands centered at about 2.45 and 5.5 GHz can be obtained, yet the antenna shows a simple and compact structure with a length of 20 mm only. Detailed design considerations of the antenna are described in the paper, and results for the constructed prototype are presented and discussed. Effects of major parameters on the antenna performances are also analyzed.
Troop‐specific responses to long calls of isolated tamarins (Saguinus mystax)

Recently captured moustached tamarins (Saguinus mystax) were briefly separated from other members of their troop. Most separated animals emitted long calls that were, in general, similar in acoustic structure to those of sympatric tamarin species while retaining species distinctiveness. Individual differences also appeared in call structure. The long calls of a separated animal were responded to almost entirely by members of the animal's own troop rather than by other troops, and reciprocal calling occurred among troop members significantly more often than expected by chance. Although there was no evidence of troop‐specific call structure or dialect, there were troop‐specific responses to the calls of separated tamarins. This response implies the existence of a stable and integrated troop structure that allows troop members to learn and to respond to the individual specific features of each troop member's calls.
Fibroblasts Spread on Immobilized Fibrin Monomer by Mobilizing a β1-class Integrin, Together with a Vitronectin Receptor αvβ3 on Their Surface*

Human and murine fibroblasts were found to spread far more avidly on fibrin monomer monolayers than on immobilized fibrinogen, indicating that removal of fibrinopeptides by thrombin is a prerequisite for the fibrin-mediated augmentation of cell spreading. In fact, cell spreading was not efficiently augmented on monolayers of a thrombin-treated dysfibrinogen lacking the release of fibrinopeptide A due to an Aα Arg-16 → Cys substitution. Since a synthetic Arg-Gly-Asp (RGD)-containing peptide inhibited the fibrin-mediated cell spreading, subsequent dissociation of the carboxyl-terminal globular domain of the Aα-chains appears to render the RGD segments accessible to the cell-surface integrins. In support of this, fibrin-augmented cell spreading was inhibited by an antibody recognizing a 12-kDa peptide segment with γ Met-89 at its amino terminus, which is located in close association with the RGD segment at Aα 95-97 in the helical coiled-coil interdomainal connector. The fibrin-mediated augmentation of cell spreading was inhibited not only by an antibody against human vitronectin receptor (LM 609) but also by an antibody against the β1 subunit of integrin (mAb13), suggesting that the β1-class integrin together with a vitronectin receptor, αvβ3, is mobilized onto the surface of fibroblasts upon contact with the fibrin monomer monolayer.
GROWTH AND DEVELOPMENT OF THE MARIANA SWIFTLET

Abstract The Mariana Swiftlet (Aerodramus bartschi) on Saipan lays a single white egg which is incubated for 22.95 days (range 17–30 days). Newly hatched nestlings are naked and weigh 1.11 g (range 1.0– 1.2 g). Nestlings grow slowly, reaching asymptotic weight on day 29 and fledging after 46.8 days (range 40– 55 days). Post-asymptotic weight recession is ±2% and nestlings fledge at slightly above adult weight of 8.01 g. Wing and tail length are >94% of adult size at fledging. Low clutch size, slow chick growth, and extended nestling period are characteristic of other species of swiftlets and may represent food limitation in these diminutive aerial insectivores.

The Super Elongation Complex (SEC) in development and disease

Chromosomal translocations involving the mixed lineage leukemia (MLL) gene are associated with infant acute leukemia. There are a large number of translocation partners of MLL that share very little sequence similarities, yet their translocations into MLL result in the pathogenesis of leukemia. To define the molecular reason why these translocations result in leukemogenesis, I purified several of the commonly occurring MLL chimeras and identified a novel Super Elongation Complex (SEC) associated with all chimeras purified. SEC consists of the RNA Pol II elongation factors ELL1-3, P-TEFb, and several frequent MLL-translocation partners. SEC is one of the most active P-TEFb complexes and is required for the proper expression of MLL chimera target genes and the oncogene, MYC, suggesting that the regulation of transcription elongation checkpoint control (TECC) by SEC could play essential roles in leukemia. Paused Pol II has been proposed to be associated with loci that respond rapidly to environmental stimuli. My studies in mouse ES cells demonstrated that SEC is required for rapid transcriptional activation of genes, many of which contain paused Pol II. However, SEC is also required for the activation of the Cyp26al gene, which does not contain detectable Pol II, yet responds much more rapidly to retinoic acid than those paused genes, suggesting that paused Pol II is not a prerequisite for rapid gene activation. Furthermore, Ell3, a member of the ELL family of proteins, predominately occupies poised, active, and inactive enhancers of many developmental genes in ES cells. Ell3’s association with enhancers is required for setting up proper Pol II occupancy at the promoter-proximal regions of neighboring genes, providing a yet to be discovered mechanism for the transition from Ell3’s presence at poised enhancers in ES cells to Ell2’s role in the release of paused Pol II during gene activation.
Increased knowledge and scientific thinking following participation of school students in air-quality research

Public participation in scientific research, also known as citizen science, is claimed to have many social, educational and civil benefits for participants. The current study focuses on students’ participation in an air-quality citizen science initiative in schools. As part of the European "CITISENSE" project for developing sensor-based citizen observatories, air-quality sensors which continuously monitor air-quality were installed within school premises. Seventh grade students participated in different stages of the research including planning sensor locations, developing research questions and analyzing air-quality data. Students’ knowledge, attitude, behavior, and scientific and critical thinking regarding air-quality were examined using pre and post questionnaires. Results demonstrate an increase in students' content knowledge and scientific thinking (p<0.05), but no difference in attitude, behavior or critical thinking. These results exhibit the educational benefits of citizen science for knowledge construction and scientific understanding and provides better understanding of the potential use of citizen science as a learning method.
Riparian vegetation recovery patterns following stream channelization: a geomorphic perspective

Hundreds of kilometres of West Tennessee streams have been channelized since the turn of the century. After a stream is straightened, dredged, or cleared, basin- wide ecologic, hydrologic, and geomorphic processes bring about an integrated, character- istic recovery sequence. The rapid pace of channel responses to channelization provides an opportunity to document and interpret vegetation recovery patterns relative to otherwise long-term, concomitant evolution of river geomorphology. Nearly 150 sites along 15 streams were studied in the Obion, Forked Deer, Hatchie, and Wolf River basins. Channels of these streams, except that of the Hatchie River main stem, have undergone major modi- fications along all or parts of their courses. This paper presents the eco-geomorphic analyses and interpretation of a large multidisciplinary study, with special reference to the inter- related hydrogeomorphic aspects of channel recovery. Quantitative plant ecological anal- yses were conducted to infer relative bank stability, to identify indicator recovery species, and to determine patterns of vegetation development through the course of accelerated channel evolution. Binary-discriminant and ordination analyses show that distinctive ri- parian-species patterns reflect a six-stage model of channel evolution and can be used to infer channel stability and hydrogeomorphic conditions. Woody vegetation initially estab- lishes on low- and mid-bank surfaces at the same location and time that bank accretion begins, and corresponds to the site of initial geomorphic restabilization. The linkage of channel bed aggradation, woody vegetation establishment, and bank accretion all lead to recovery of the channel. Pioneer species are hardy and fast growing, and can tolerate moderate amounts of slope instability and sediment deposition; these species include river birch (Betula nigra), black willow (Salix nigra), boxelder (Acer negundo), and silver maple (Acer saccharinum). High stem densities and root-mass development appear to enhance bank stability. Tree-ring analyses suggest that on average 6 5 yr may be required for recovery after channelization.
Vegetation Productivity/Stability and Other Possible Ecological Invariant Relationships Demonstrated in a Microplot Multispecies Pasture Sward

The relationship between vegetation functional characteristics of production, stability and descriptive characteristic of species diversity or dominance, and other possible compositional invariants were investigated in 2400 micro-plot sward of 20 species at randomly assigned positions and using different matrix sizes of adjacent plots and four harvest to derive a combination of “vegetations” of differing species configurations.Within the highest frequency section of the data there was little relationship between productivity and stability (deviance) and either species diversity or dominance (% contribution of 1st ranked species). However, considering all data, productivity increased with increasing dominance and was unrelated to species diversity, while stability increased with diversity. Of single parameters combining diversity and dominance, the gradient of the log abundance/rank relationship was superior to Shannon H, with both showing productivity increasing with dominance rather than diversity. The fate of individual micro-plots from a mixed species stand through successive harvests was consistent with the −3/2 thinning rule, though with species cumulative yields. The abundance/rank relationship was compared with many models. Where there was simultaneous fitting to both density and biomass relationships, self-thinning random particle packing models were best and offered an explanation of the process. The positive correlation between regional and local frequency was related to sample area in a random placement model. Observed species composition and mortality was simulated by consideration of plant size related growth and mortality, initial establishment, growth potential and variation in plant size.

Preference and performance responses of California grape phylloxera to different Vitis rootstocks

Laboratory experiments on host preference and performance were simultaneously conducted with Cabernet Sauvignon, AXR#1, and 5C Vitis rootstocks for the California biotypes A and B grape phylloxera. Preference bioassays recorded over a 3‐day period indicated that phylloxera exhibit differential host choice. AXR#1 is antixenotic to biotype A, and 5C is antixenotic to both phylloxera biotypes. Preferences observed with biotype B for Cabernet Sauvignon and AXR#1 were not statistically different, whereas biotype A had shown a significant preference for Cabernet Sauvignon. On 5C the preferences scored were significantly lower than on either of the other two rootstocks, and there was no significant difference beetween biotypes. Performance bioassays recorded over a 29‐day period indicated that survival, development, and reproduction of both biotypes were affected by Vitis rootstock. Both biotypes were unable to survive or develop on 5C suggesting the presence of antibiotic resistance in 5C against these phylloxera biotypes. The antibiotic effects observed with AXR#1 against biotype A were expressed as significant reductions in survival, development, and reproduction. Performance of biotype B on AXR#1 was similar to its performance on Cabernet Sauvignon. For both AXR#1 and 5C rootstocks and both phylloxera biotypes A and B the antibiotic mechanism was considerably stronger than the antixenotic mechanism. This research indicated that host preference and performance are positively correlated in grape phylloxera with the rootstocks and phylloxera biotypes tested.
Floral resources, body size, and surrounding landscape influence bee community assemblages in oak‐savannah fragments

Fragmentation of natural habitats due to urban development is predicted to have negative impacts on species diversity. The surrounding landscape (or ‘matrix’) of urban or semi‐natural habitats can sometimes support biodiversity, but the amount of support will depend on species‐specific traits, and on the resources available in the fragment and the matrix. Using data on bees collected from 19 oak‐savannah fragments, the question of whether bee communities differ when fragments are embedded in different landscapes (Douglas‐fir forest vs. urban residential neighbourhoods) was investigated, and also whether these differences could be attributed to species‐specific traits of bees (e.g. body size, specialization) and/or within‐fragment floral resources. No differences were found in overall richness or abundance of bees, but there were distinct differences in plant and bee community composition between matrix types. Common wood‐nesters and late‐flying, small‐bodied bees tended to be found in urban‐associated fragments, which also had a lower availability of within‐fragment floral resources. Forest‐associated fragments, on the other hand, had a greater density and richness of early‐flowering native plant species, and supported a higher abundance of large‐bodied bee species. Bumble bee abundance, in particular, increased with increasing proportion of forest cover in the surrounding landscape. Large‐bodied bees appear to respond to increased availability of within‐fragment floral resources, but it was also hypothesised that nesting and floral resources in matrix habitat drive the differences in bee community assemblages.
INFLUENCE OF KNOTS ON CLASSIFICATION OF TIMBER ASSORTMENTS OF SILVER FIR INTO QUALITY CLASSES

Th e classifi cation of timber assortments of silver fi r into quality classes depends on the occurrence of wood defects. Knots are the most common defects appearing on fi r assortments. Th e aim of this research was to establish the infl uence of size of knots and their position/height on fi r trees (Abies alba, Mill.) on classifi cation into quality classes of timber assortments that can be processed from the stem. Heights above ground, where maximum knot diameters can be found, increase with the increase of tree diameter at breast height. Only lower parts of stem of fi r-trees can be used for processing veneer logs. Timber assortments processed from upper parts of trees with smaller-breast height diameter can be classifi ed as saw logs of the highest quality (Class 1), but the quality class depends on the stem diameter. With larger breast height diameter trees timber assortments processed from the lower third of the stem meet the criteria for saw logs of the highest quality (Class 1).
Does IFRS Impact on Indonesian Financial Reporting Quality and Performance? A Case Study of Companies in Indonesia

In 2011, IFRS was adopted in Indonesia using the convergence method. This research aims to evaluate the hypothesis that IFRS could improve accounting quality and comparability. Using the indicators of income smoothing, timely loss recognition, earnings management by modified Jones, and performances, the results are found to be different from previous research where sample companies are derived from companies with the highest market capitalisations. The sample used in this research is the companies that are consistently found in the KOMPAS100 index during 2007-2018. This finding contributes to the literature of financial reporting standards and re-evaluates whether the internationalisation of accounting standards provides the best practice for financial reporting.
Cuteness and Singer’s Expanding Moral Circle: Examining Cuteness as a Moral Issue

This essay will show visual cuteness to be a biological phenomenon where viewing the specific proportions of baby-schema causes an innate releasing mechanism to respond, thus creating a consistent group of reactions in viewers. Those reactions will be shown to create a ‘halo’ effect that is similar but distinct from the attractiveness halo effect. The cuteness effect will be demonstrated to be consistent with both the caregiving effect proposed by Lorenz and the social effect proposed by Sherman and Haidt. The totality of those effects will be shown to be morally relevant in relation to the ethical theory of Singer, especially the concept of the expanding moral circle. Through examining recent studies on cuteness and relating those studies to the ethical theories of Singer a few obvious practical moral implications are created. Two of those implications will be examined to show that cuteness can be used to inform the practice of photolisting for adoption agencies and inform the justice system of a potential bias that remains unaccounted for. However, the potential for cuteness to create/explain moral reactions isn’t limited to niche areas as the final section of this essay will document cuteness’s broader ability to increase moral concern and account for moral reactions in a broader way.
Efficient transformation mediated by Agrobacterium tumefaciens with a ternary plasmid in Pharbitis nil

Pharbitis nil Choisy has a large number of mutants and is well known in classical genetics. The mutants exhibit particularly rich and varied floral colors and patterns compared to other plants. P. nil is a typical short-day plant and has therefore been used as a model plant for the genetic analysis of floral colors and patterns and for the photoperiodic induction of flowering. In this paper, we describe an efficient transformation protocol mediated by Agrobacterium tumefaciens in P. nil. The binary vector pBI121, containing the neomycin phosphotransferase II (NPT II) gene, was used as a selectable marker, and the luciferase (Luc+) gene was used as a reporter instead of β-glucuronidase (GUS). Agrobacterium tumefaciens strain GV3101 is carried in the binary vector, while that of LBA4404 is contained the binary and ternary vector, which expresses a constitutive virG mutant gene (virGN54D). We infected 393 somatic embryos with the Agrobacterium strain LBA4404/virGN54D/pBI121-Luc+. Fifty-seven kanamycin-resistant shoots were obtained after 2–3 months of culturing in a selection medium, and over 20% of the regenerated shoots were transgenic. Transformation was confirmed with PCR analysis, Southern hybridization, and Luc assay of the transgenic plants. All transgenic plants were morphologically normal and were fertile. The transformation efficiency in this study reached 3.1% of treated explants, which is high enough to produce transgenic P. nil with genes of interest.
