Karyotyping and single-gene detection using fluorescence in situ hybridization on chromosomes of Hydra magnipapillata (Cnidaria: Hydrozoa)

The fresh water polyp Hydra L. , 1758 (Cnidaria, Hydrozoa) plays a key role as a model organism in modern evolutionary and developmental biology. A complete genome sequence has been published recently for Hydra magnipapillata Ito, 1947 and molecular data are rapidly accumulating in the literature, but little information is avail- able on its chromosomes. In this study, an effi cient fl uorescence in situ hybridization (FISH) method is described for H. magnipapillata which not only allows identifi cation of the chromosomes but also visualization of the location of individual genetic loci. Together with cDNA and genomic sequencing this may provide the foundation for in- creasingly precise genetic and physical mapping in this basal metazoan model organism.
Eucerin impedes transdermal insulin delivery by sonophoresis in rats

The present study was designed to further evaluate the effect of low-frequency ultrasound on transdermal delivery of insulin as an ointment. Forty-two Wistar rats were randomly divided into 7 groups including one control and six experimental groups with six rats in each group. An ointment of insulin was prepared and applied (alone and with low-frequency ultrasound) on the skin of animals. In all the groups, blood samples were collected from the tail vein of the animals every 15 minutes of the whole 90-minute experiment. The changes of blood glucose levels with time were assessed in the groups. The results of this study showed that the exposure of the insulin ointment to low-frequency ultrasound for a period of 60 minutes significantly decreased its potency in lowering the blood glucose levels. We conclude that eucerin impedes transdermal insulin delivery by sonophoresis in rats. We suggest that the lowering effect of ultrasound on the penetration ability of insulin is probably due to its effect on the specific molecular structure formed between the insulin and the ointment base after its preparation. However, further studies are needed in order to more precisely identify the involving mechanisms.

An Online Energy Management System for a Grid-Connected Hybrid Energy Source

An online energy management system (EMS) for a grid-connected hybrid energy source is proposed in this paper. The hybrid source combines renewable energy resources (wind and photovoltaic), battery storage, variable speed diesel generator, and load management system. The proposed EMS consists of two-level optimization algorithm: 1) the rolling optimization and 2) the feedback intrasample correction. The rolling optimization part is established to schedule operation based on the forecast data using the model-predictive control approach. The rolling dispatch scheduling is then adjusted based on an intrasample feedback correction that compensates for the prediction error of the forecast data. The optimization problem was formulated as mixed-integer linear programming framework with two objectives: 1) to minimize the total operating cost and 2) to minimize the pollutant gas emissions. The battery daily number of cycles and the minimum state of charge are considered as decision variables that are optimally determined by the EMS to minimize the total system operating cost while considering all the practical constraints of the different energy sources. Different case studies with different market profiles demonstrate the effectiveness of the proposed approach, and the results have showed a significant reduction in the total system cost.
Challenges implementing work-integrated learning in human resource management university courses

The examination of work-integrated learning (WIL) programs in the undergraduate Human Resource Management (HRM) curriculum is an area under-represented in the Australian literature. This paper identifies the challenges faced in implementing WIL into the HRM undergraduate curriculum. Qualitative semi-structured interviews were conducted with 38 participants including academics, careers advisors, professionals and students from nine Australian universities. The findings show that a lack of resources, a clash of agendas, legal and ethical issues, expectations, the HRM profession and academic perspectives of WIL, are impacting on how WIL programs in HRM are being developed. Recommendations are made for the future development of WIL in HRM.
Automatic Prediction of Cybersickness for Virtual Reality Games

Cybersickness, which is also called Virtual Reality (VR) sickness, poses a significant challenge to the VR user experience. Previous work demonstrated the viability of predicting cybersickness for VR 360°videos. Is it possible to automatically predict the level of cybersickness for interactive VR games? In this paper, we present a machine learning approach to automatically predict the level of cybersickness for VR games. First, we proposed a novel ranking-rating (RR) score to measure the ground-truth annotations for cybersickness. We then verified the RR scores by comparing them with the Simulator Sickness Questionnaire (SSQ) scores. Next, we extracted features from heterogeneous data sources including the VR visual input, the head movement, and the individual characteristics. Finally, we built three machine learning models and evaluated their performances: the Convolutional Neural Network (CNN) trained from scratch, the Long Short-Term Memory Recurrent Neural Networks (LSTM-RNN) trained from scratch, and the Support Vector Regression (SVR). The results indicated that the best performance of predicting cybersickness was obtained by the LSTM-RNN, providing a viable solution for automatically cybersickness prediction for interactive VR games.
Hydroxyapatite Reinforced Chitosan and Polyester Blends for Biomedical Applications

Summary: Hydroxyapatite, chitosan, and aliphatic polyester were compounded using a twin-screw extruder. The polyesters include poly(e-caprolactone) (PCL), poly(lactic acid) , poly(butylene succinate) (PBS), and poly(butylene terephthalate adipate). The mass fraction of chitosan ranged from 17.5 to 45%, while that of HA ranged from 10 to 30%. These blends were injection molded and evaluated for thermal, morphological, and mechanical properties. The addition of hydroxyapatite decreased the crystallinity in chitosan/PBS blends, while in blends containing chitosan/PCL, the crystallinity increased. Addition of hydroxyapatite significantly decreased the tensile strength and elongation of polyester/ hydroxyapatite composites as well as chitosan/polyester/ hydroxyapatite composites with elongations undergoing decreases over an order of magnitude. The tensile strength of the composite was dictated by the adhesion of HA to the chitosan/polyester matrix. The tensile strength of composites containing hydroxyapatite could be predicted using the Nicolai and Narkis equation for weak filler adhesion (K � 1.21). Tensile-fractured and cryogenically-fractured surface indicates extensive debonding of hydroxyapatite crystals from the matrix, indicating weak adhesion. The adhesion of hydroxyapatite was higher for pure polyester than those containing chitosan and polyester. The modulus of the composites registered modest increase. The two main diffraction peaks observed using WAXS are unaffected by the amount of chitosan or hydroxyapatite.
Nutritive Value Assessment of Ensiling or Mixing Acacia and Atriplex Using In Vitro Gas Production Technique

A gas production was continuously measured by incubating samples in buf fered r umen fluid f rom c annulated sheep f or 96 h. Cumulative gas production was recorded at 3, 6, 9, 12, 24, 48, 72 and 96 h of incubation per iods and kinetics of gas production was described. The crude protein ( CP) was ranged on average from 126 to 144.5 g/kg D M. The hi ghest value o f CP was recorded with H ay and the lowest value was recorded with A cacia S. The highest value of crude fibre (CF) was 277.3 g /kg DM for Hay and t he lowest value was almost similar for A triplex S, the mixture of acacia a nd at riplex silages (AAS) and Acacia S (202.1, 202.3 and 202.4 g/kg DM, respectively). As for ash content, the highest value was observed with F. Atriplex (27 2.7 g/kg D M) and the l owest value was 140.7 g/kg D M for H ay. The value of nitrogen free extract (NFE) was ranged on average between 345.9 and 519.7 g/kg DM. The same manner of chemical composition was observed with t he res ults of fibre f ractionations.

The STAGES view of red spirals and dusty red galaxies: Mass-dependent quenching of star formation in cluster infall

We investigate the properties of optically passive spirals and dusty red galaxies in the A901/2 cluster complex at redshift ∼0.17 using rest-frame near-ultraviolet–optical spectral energy distributions, 24-μm infrared data and Hubble Space Telescope morphologies from the STAGES data set. The cluster sample is based on COMBO-17 redshifts with an rms precision of σcz ≈ 2000 km s −1 . We find that ‘dusty red galaxies’ and ‘optically passive spirals’ in A901/2 are largely the same phenomenon, and that they form stars at a substantial rate, which is only four times lower than that in blue spirals at fixed mass. This star formation is more obscured than in blue galaxies and its optical signatures are weak. They appear predominantly in the stellar mass range of log M∗/M� = [10, 11] where they constitute over half of the star-forming galaxies in the cluster; they are thus a vital ingredient for understanding the overall picture of star formation quenching in clusters. We find that the mean specific star formation rate (SFR) of star-forming galaxies in the cluster is clearly lower than in the field, in contrast to the specific SFR properties of blue galaxies alone, which appear similar in cluster and field. Such a rich red spiral population is best explained if quenching is a slow process and morphological transformation is delayed even more. At log M∗/M� < 10, such galaxies are rare, suggesting that their quenching is fast and accompanied by morphological change. We note that edge-on
The Other-Race Effect in Caucasian and Japanese-Descendant Children in Brazil: Evidence of Developmental Plasticity

The Other-Race Effect has been confirmed by several experimental studies, in which the individual has greater difficulty in recognizing the faces of races that are different from their own. Few studies have investigated this effect during the development of the face processing system. The aim of this study was to investigate the development of the Other-Race Effect in Caucasian and Japanese-descendants children born and living in Brazil. Seventy-four children, split into two age groups (5 - 7 and 9 - 11 years of age), were tested. Japanese-descendant children did not present the effect in favor of their own-race faces, whereas Caucasian children demonstrated the effect in both age groups. This indicates that the effect is present early in the development of face recognition and that contact with the faces of another race during childhood dissipates it. These findings suggest that experience with faces from the children’s visual context is crucial for shaping face processing.
MOOD DURING COMMUTE IN THE NETHERLANDS What way of travel feels best for what kind of people?

Question: How happy we are depends partly on how we live our life and part of our way of life is the commute between home and work. In this context we are faced with the question of how much time spent on commuting is optimal happiness wise, and what means of transportation. Since our personal experience is limited, it is helpful to draw on the experience of other people, of people like us in particular. Earlier research : Several cross-sectional studies have found lower subjective wellbeing among long-distance commuters and among users of public transportation. Yet these differences could be due to selection effects, such as unhappy people ending up more often in distant jobs without having a car. Still another limitation is that earlier research has focused on the average effect of commuting, rather than specifying what is optimal for whom. Method : Data of the Dutch ‘GeluksWijzer’ (Happiness Indicator) study were analyzed, in the context of which 5000 participants recorded both what they had done in the previous day and how happy they had felt during these activities. This data allows comparison between how the same person feels at home and during their commute. The number of participants is large enough to allow a split-up between different kinds of people, in particular among the many well-educated women who participated in this study. Results : People feel typically less well when commuting than at home, and this negative difference is largest when commuting using public transportation and smallest when commuting by bike. It is not per se the commuting time that depresses mood, but specific combinations of commuting time and commuting mode. Increasing commuting times can even lead to an uplift of mood when the commute is by bike or foot. Split-up by different kinds of people shows considerable differences, especially with regard to the different modes and company when travelling. Optimal ways of commuting for different kinds of people are presented in a summary table, from which individuals can read what will fit them best. The differences illustrate that research focusing on averages will not help individuals to make a more informed choice with respect to commuting mode.
Searches for electron interactions induced by new physics in the EDELWEISS-III germanium bolometers

We make use of the EDELWEISS-III array of germanium bolometers to search for electron interactions at the keV scale induced by phenomena beyond the Standard Model. A 90% C.L. lower limit is set on the electron lifetime decaying to invisibles, τ>1.2×1024 years. We investigate the emission of axions or axionlike particles (ALPs) by the Sun, constraining the coupling parameters gae<1.1×10-11 and gae×gaNeff<3.5×10-17 at 90% C.L. in the massless limit. We also directly search for the absorption of bosonic dark matter particles that would constitute our local galactic halo. Limits are placed on the couplings of ALPs or hidden photon dark matter in the mass range 0.8–500 keV/c2. Prospects for searching for dark matter particles with masses down to 150 eV/c2 using improved detectors are presented.
Organic spin valves with inelastic tunneling characteristics

Electrons may experience inelastic coupling with the organic spacer layer during tunneling between two ferromagnetic electrodes. To probe the transport behavior of spin-polarized electrons in organic materials, organic spin valves were fabricated utilizing a relatively thin organic barrier of 3,4,9,10-perylene-teracarboxylic dianhydride (PTCDA) dusted with alumina at the organic/ferromagnetic interfaces. These structures, with an organic barrier layer, exhibited magnetoresistance up to 12% at room temperature. In studies of the inelastic tunneling spectrum, the observed characteristic peak of the organic layer provides direct evidence of the interplay between the spin-polarized electrons and the organic molecules. Combining the inelastic tunneling results with a simple molecular vibration calculation yields further information on the configuration of the molecular thin film and the possible tunneling states of the spin-polarized electrons. Such interplay indicates a true transport of spin-polarized electrons through organic material rather than through defects or interdiffusion compounds formed at the interfaces within the organic spin valve.
Do the Data Support a Large Meteorite Impact at Chicxulub ?

Chicxulub, Mexico has become synonymous with the dinosaur extinction in the secular literature. It is often referred to as the “smoking gun. ” But how much of the data really support an asteroid impact? This paper reviews the history of the Chicxulub site and critically examines all the pertinent data. It addresses the findings of the most recent well drilling activity, the earlier oil wells at the site, and all relevant geophysical data. Many surprising results are discussed, including the less than expected amounts of diagnostic high pressure minerals, the limited amounts of pseudotachylyte and iridium and even the lack of significant melt-rich rock. Alternative explanations are offered to explain the shocked quartz, ring faults and the claimed “peak ring. ” The ambiguous nature of the gravity anomaly is addressed and an alternative interpretation is offered. Conclusions are made that indicate the evidence for a large impact at Chicxulub may not be as strong as generally believed. A case can also be made that there was no impact. Although some meteorites likely struck the earth during the Flood, creation scientists need to critically assess each site before incorporating them into their Flood models.
Reexamination of the Crustal Boundary Context of Mesoproterozoic Granites in Southern Nevada Using U-Pb Zircon Chronology and Nd and Pb Isotopic Compositions

Granites crystallize from melts with a range of compositions and textures that provide important clues about the evolution of the continental crust. Rapakivi or A-type granites are usually inferred to be unrelated to active tectonic processes. Granites that fall into this category are widespread across the interior of North America. They are generally considered to be 1450–1400 Ma and anorogenic. We report new and substantially older U-Pb zircon ages of 1683.2 ± 4.7, 1681.4 ± 5.1, and 1683.3 ± 6.1 Ma for rapakivi granites from the Davis Dam area, the Lucy Gray Range, and the Newberry Mountains of southern Nevada, respectively. These granites are thus associated with the Ivanpah orogeny. Rapakivi granites from Gold Butte, Nevada, also previously thought to be 1450–1400 Ma, yielded a younger U-Pb zircon age of 1373 ± 23 Ma. In addition to these new age constraints, new Nd and Pb isotope data allow us to refine previously mapped isotopic crustal boundaries. Nd and Pb isotopes from the ~1680 Ma granites indicate a brief residence in the crust prior to crystallization, whereas the source of the younger Gold Butte granite appears to have significant crustal heritage. The modified isotopic province boundaries are now more consistent with each other than in earlier interpretations, a result that reinforces the view that these boundaries reflect fundamental tectonic features related to Paleoproterozoic crustal accretion. Our data imply that the spatial distribution of the classic anorogenic granite suite in North America is more restricted than previously thought. They also draw attention to the need for more extensive dating and radiogenic isotope measurements to probe the midcontinent belt of granites more broadly. Although plutons look alike, it can no longer be assumed that they were intruded synchronously or formed from the same source.
ANALYSIS OF ROUNDABOUT PERFORMANCE BY MODELING APPROACH-FLOW INTERACTIONS

An analytical method for estimating roundabout entry-lane capacity and performance measures is presented. The method is based on modeling the gap-acceptance process that takes place in real-life roundabout operation. Unlike past studies that treated roudabouts as a series of t-junctions, the method presented here allows for approach-flow interactions. A factor is used to adjust the basic gap-acceptance capacity for the effects of origin-destination pattern and the queueing characteristics of the approach flows. Circulating stream characteristics are determined considering the approach-lane use characteristics of the traffic streams that constitute the circulating flow. The modeling of interactions among approach flows is important, especially in heavy and unbalanced demand flow cases. Ignoring approach-flow interactions can cause serious overestimation of capacity and underestimation of delays and queue lengths, especially for multi-lane roundabouts with unbalanced flow patterns. This is demonstrated through a case study that compares the results from the methods with and without approach-flow interactions. Formulae are presented for the estimation of stop-line delay, queue length, proportion queued, queue clearance time, and queue move-up rate. These formulae also allow for the effects of any initial queued demand at the start of the analysis period. The difference between the cycle-average queue and the average back of queue is emphasized.
Forward Regression for Ultra-High Dimensional Variable Screening

Motivated by the seminal theory of Sure Independence Screening (Fan and Lv 2008, SIS), we investigate here another popular and classical variable screening method, namely, forward regression (FR). Our theoretical analysis reveals that FR can identify all relevant predictors consistently, even if the predictor dimension is substantially larger than the sample size. In particular, if the dimension of the true model is finite, FR can discover all relevant predictors within a finite number of steps. To practically select the “best” candidate from the models generated by FR, the recently proposed BIC criterion of Chen and Chen (2008) can be used. The resulting model can then serve as an excellent starting point, from where many existing variable selection methods (e.g., SCAD and Adaptive LASSO) can be applied directly. FR’s outstanding finite sample performances are confirmed by extensive numerical studies.
