AbstractThe transition from the Middle to Late Pre-Pottery Neolithic B (PPNB) happened throughout southwest Asia in the mid-8th millennium cal BC. It entailed the abandonment of a number of sites, rapid growth of others, as well as the wide spread of morphologically domestic caprines. What remains an unknown is how rapid these processes were in real time. Over the period when the transition was taking place, the calibration curve has two shallow sections divided by a sudden drop, which for many of the older dates creates an illusion of a sudden cultural break around 7600–7500 cal BC. Yet a more detailed study presented in this paper suggests that the transition event could have been spread over a more extended period of time. This, however, is still far from certain due to risks of old wood effects and complexities of site formation.

Abstract Color displays of the velocities of precipitation particles detected with a C-band Doppler radar in wide-spread cyclonic storms provide a variety of real-time information on the atmospheric wind field.Vertical profiles of wind speed and direction indicated by the real-time color displays agree well withrawinsonde measurements. Veering winds (or warm advection) produce a striking S-shaped pattern onthe color display and backing winds (or cold advection) produce a backward S. A maximum in the verticalprofile of wind speed is indicated by a pair of concentric colored rings, one upwind and one downwind ofthe radar. Vertically sloping velocity maxima are indicated by asymmetries in the color displays, as areconfluent and difluent winds. Divergence and convergence computed from the real-time color displays areof reasonable magnitude.

The Effect of Sorting, Sodium hypochloride (NaClO), and Fungicide Treatment on Peanut  in Elimination  the  Aspergillus flavus Contamination.  The humid tropical condition of Indonesia, the post harvest treatment, and the storage practices favour rapid growth and wide spread Aspergillus infestation on peanut. The objectives of this research was to find the best technique in controlling the Aspergillus infection on peanut.  To achieve those objectives, complete randomised design in factorial with three factors was applied.  The factors were grading and colour sorting (A1 = grading and colour sorting;  A2 = without grading and colour sorting), NaClO blanching (B1 = without blanching; B2 = 1.25% NaClO blanching; B3=2.5% NaClO blanching), and Benlate T-20 WP treatment (C1 = 2,5 g/L; C2 = 3 g/L;  C3 = 3,5 g/L).  The result showed that the best combination treatment was A2B2C3 with the minimum amount of spore on peanut seed.  With those combination treatment we concluded that the grading and colour sorting, the 1.25% NaClO blanching, and the application of 3,5 g/L Benlate T-20 WP could reduced the Aspergillus contamination up to 80% compare with A1B1C3 treatment.

ABSTRACTThe real-time quantitative polymerase chain reaction (qPCR) is routinely used for quantification of nucleic acids and is considered the gold standard in the field of relative nucleic acid measurements. The efficiency of the qPCR reaction is one of the most important parameters that needs to be determined, reported, and incorporated into data analysis in any qPCR experiment. The Minimum Information for Publication of Quantitative Real-Time PCR Experiments (MIQE) guidelines recognize the calibration curve as the method of choice for estimation of qPCR efficiency. The precision of this method has been reported to be between SD=0.007 (3 replicates) and SD=0.022 (no replicates). In this manuscript we present a novel approach to analysing qPCR data obtained by running a dilution series. Unlike previously developed methods, our method relies on a new formula that describes pairwise relationships between data points on separate amplification curves and thus operates extensive statistics (hundreds of estimations). The comparison of our method with classical calibration curve by Monte Carlo simulation shows that our approach can almost double the precision of efficiency and gene expression ratio estimations on the same dataset.

The rapid growth of sensor-enabled smartphone is driven phenomena of common interest to be observed while leveraging people mobility and their sensory data collection. This paradigm known as mobile crowdsensing has demonstrated its efficiency in data collection over the last years, enabling the monitoring of traffic, pollution, people density and more. However, it stills pose interesting challenges, with particular regard to the management of collected data, dealing with their presentation and standardization in an interoperable infrastructure. Current visions of future crowdsensing systems share common goal of integrating those data into powerful real time web services accessible and discoverable via the web. In this paper the authors dig into this axis and define several criteria that allow succeeding it. They pay particular attention to semantic description and discovery techniques and evaluate proposed approaches by defining their strengths and shortcomings. The authors also propose guidelines for future researches.

Turbidity is a key environmental parameter that is used in the determination of water quality. The turbidity of a water body gives an indication of how much suspended sediment is present, which directly impacts the clarity of the water (i.e., whether it is cloudy or clear). Various commercial nephelometric and optical approaches and products exist for electronically measuring turbidity. However, most of these approaches are unsuitable or not viable for collecting data remotely. This paper investigates ways for incorporating a turbidity sensor into an existing remote aquatic environmental monitoring platform that delivers data in near real-time (i.e., 15-min intervals). First, we examine whether an off-the-shelf turbidity sensor can be modified to provide remote and accurate turbidity measurements. Next, we present an inexpensive design for a practical light attenuation turbidity sensor. We outline the sensor’s design rationale and how various technical and physical constraints were overcome. The turbidity sensor is calibrated against a commercial turbidimeter using a Formazin standard. Results indicate that the sensor readings are indicative of actual changes in turbidity, and a calibration curve for the sensor could be attained. The turbidity sensor was trialled in different types of water bodies over nine months to determine the system’s robustness and responsiveness to the environment.

Abstract Background: Despite the increasing use of real-time PCR in the diagnosis and management of viral infections, there are no published studies adequately addressing the optimum number of calibrators, the number of replicates of each calibrator, and the frequency with which calibration needs to be repeated. This study was designed to address these issues. Methods: Cycle threshold data (ABI 7700) was collected from >50 consecutive real-time PCR runs for hepatitis B and Epstein–Barr viruses. Our routine calibration curve made from serial 10-fold dilutions run in duplicate was compared with alternative options, including duplicate 100-fold dilutions, inclusion of a low-copy calibrator, and omission of the duplicate determination. Control data were used to examine the use of an average calibration curve made from multiple runs. Results: Use of duplicate serial 10-fold dilutions led to the least imprecision, duplicate 100-fold dilutions had slightly higher imprecision, and calibration curves obtained with singlet measurements showed the greatest imprecision. For patient data, the duplicate 100-fold dilution calibration curve produced results that best matched those from the routine calibration curve. Use of singlet dilutions or inclusion of a low-copy calibrator produced poorer agreement. Variability in controls was lower with a daily calibration curve than with an average calibration curve. Conclusions: Duplicate 100-fold dilution calibration curves produced equivalent results and the same imprecision as curves with more calibrators, and thus are a valid alternative. Laboratories should carefully evaluate the variability resulting from the use of average calibration curves before adopting this approach.

Realistic Significance

The rapid growth of power grid load put forward higher requirements on the transmission capacity of line, with the growing tension of line corridors, building new transmission lines is becoming more and more difficult. Therefore, it is of realistic significance to analyze the transmission capacity of existing transmission line and fully tap the existing power grid transmission capacity. On the basis of previous studies, and consulting a large number of references, this paper summarizes and expounds the methods of improving transmission capacity by using the thermal rating analysis, introducing static thermal rating and real-time static thermal rating. Also, this paper verifies applications of the above methods in actual running environment.

Abstract Spatial continuity of the house is often seen as crucial in providing temporal depth for the Neolithic societies of southwest Asia. While an emphasis on the creation of such continuities is evinced at densely agglomerated sites, other sites are characterised by dispersal and frequent relocation of habitation. Çatalhöyük (Turkey) and Tell Sabi Abyad (Syria) appear to be at either end of this spectrum. However, recently found evidence and reinterpretation of older evidence call into question the apparently stark distinction between the two sites. The purpose of this paper is to compare aspects of the archaeological evidence from Tell Sabi Abyad and Çatalhöyük, and in doing so to understand the different ways in which site formation and social continuity were achieved. In particular, the presence of breaks in spatial continuities – an often overlooked aspect of site formation – and its implications are discussed. It appears that at these two sites both continuity and breaks gave form and meaning to the settlements and to the societies that inhabited them. We argue that social continuities and anchors to the past can be constructed in many variable ways, and that direct spatial continuity of the house is but one.
