Population history from the Neolithic to present on the Mediterranean island of Sardinia: An ancient DNA perspective

Recent ancient DNA studies of western Eurasia have revealed a dynamic history of admixture, with evidence for major migrations during the Neolithic and Bronze Age. The population of the Mediterranean island of Sardinia has been notable in these studies – Neolithic individuals from mainland Europe cluster more closely with Sardinian individuals than with all other present-day Europeans. The current model to explain this result is that Sardinia received an initial influx of Neolithic ancestry and then remained relatively isolated from expansions in the later Neolithic and Bronze Age that took place in continental Europe. To test this model, we generated genome-wide capture data (approximately 1.2 million variants) for 43 ancient Sardinian individuals spanning the Neolithic through the Bronze Age, including individuals from Sardinia’s Nuragic culture, which is known for the construction of numerous large stone towers throughout the island. We analyze these new samples in the context of previously generated genome-wide ancient DNA data from 972 ancient individuals across western Eurasia and whole-genome sequence data from approximately 1,500 modern individuals from Sardinia. The ancient Sardinian individuals show a strong affinity to western Mediterranean Neolithic populations and we infer a high degree of genetic continuity on the island from the Neolithic (around fifth millennium BCE) through the Nuragic period (second millennium BCE). In particular, during the Bronze Age in Sardinia, we do not find significant levels of the “Steppe” ancestry that was spreading in many other parts of Europe at that time. We also characterize subsequent genetic influx between the Nuragic period and the present. We detect novel, modest signals of admixture between 1,000 BCE and present-day, from ancestry sources in the eastern and northern Mediterranean. Within Sardinia, we confirm that populations from the more geographically isolated mountainous provinces have experienced elevated levels of genetic drift and that northern and southwestern regions of the island received more gene flow from outside Sardinia. Overall, our genetic analysis sheds new light on the origin of Neolithic settlement on Sardinia, reinforces models of genetic continuity on the island, and provides enhanced power to detect post-Bronze-Age gene flow. Together, these findings offer a refined demographic model for future medical genetic studies in Sardinia.
Analysis of intrasystem and intersystem interference of navigation systems with interplex modulation in the L1 band

The modernization of GPS and the Galileo system adopt the Interplex modulation to transmit multiple signals on one carrier, Interplex modulation is a particular constant envelope phase modulation through induce the intermodulation (IM) term. The main objective of this paper is to analyze the IM term effect degrees of interference that GPS and Galileo signals are expected to have in the L1 band. This paper extends the interference assessing methodologies to be applicable in the situation that accounting for IM term effects, and applies to analyze the impacts of Galileo IM term and the impacts of three versions IM term signal of GPS. Numerical results show that different nonlinear mechanism of Interplex modulation induce different degrees of interference, and the desired signals having different modulation models exhibit different degrees of sensitivities to the IM term interference effects.
Re-adaptation from alternative prey to target prey increased predation of predator on target mite

Abstract Neoseiulus bicaudus (Wainstein) is a natural enemy of spider mite and thrip and also a potential biocontrol agent for Tetranychus turkestani (Tetranychidae). Tyrophagus putrescentiae (Schrank) is an important alternative prey of N. bicaudus for mass rearing. We aimed to determine whether previous long-term feeding history, rearing on alternative prey versus target prey affected the performance of N. bicaudus. Therefore, the prey preference and functional response of predatory mites were compared between three strains: N. bicaudus fed on T. turkestani (TTS); N. bicaudus fed on T. putrescentiae (TPS); and N. bicaudus re-adapted from T. putrescentiae to T. turkestani (TPRS). When fed with the target prey, the preference rate and consumption of the TPS strain were significantly lower than the TTS strain. In addition, after 3-day-re-adaptation, the predatory mites (TPRS) increased their preference rate and consumption to target prey. The results suggested that re-adaptation before release could improve the ability of N. bicaudus to control its target prey.
Three-Stage Precise Converter in EV Charging-Discharging-Storage Integration Station

Converter in EV (electric vehicle) charging-discharging-storage integration station must satisfy the correlation objects. These include: lower harmonic and higher energy conversion efficiency, benefits to battery life, adaption to different batteries, and adjustable charging current. In this paper, we propose a three-stage circuit topology, based on precise charging control, which is able to accomplish these goals on a lithium ion polymer battery pack. It is expected that the converter will also work well on other battery chemistries. In order to use three-stage converter to charge precisely, we need to first design each stage circuit and control strategy. The final strategy can accurately capture the voltage of each DC bus and the charging current of a cell. We also give the analysis of factors affecting battery life and energy conversion efficiency, whereby the three-stage converter is in practice. Comparing with charging simulations of batteries in conventional converter, those in three-stage converter are conducted. Results are presented that that it is possible to achieve more precise charging in integrality of battery charging and extension of battery life than the conventional converter expected in an implementation.

Novel method to suppress noise in harmonically modelocked erbium fibre lasers

A novel method to suppress noise in a high harmonic mode-locked erbium fibre laser is proposed and realised for the first time, dithering the cavity length at a kilohertz rate. This method makes only one supermode in the laser dominant and suppresses the others. A fibre laser so stabilised has enabled 2.5 Gbit/s soliton transmission over 205 km fibre remaining error free for 100 min, and in a recirculating loop achieving a 10/sup -9/ bit error rate at 12000 km, respectively. >
A Tool for the Automated Collection of Space Utilization Data: Three Dimensional Space Utilization Monitor

Space Human Factors and Habitability (SHFH) Element within the Human Research Program (HRP), in collaboration with the Behavioral Health and Performance (BHP) Element, is conducting research regarding Net Habitable Volume (NHV), the internal volume within a spacecraft or habitat that is available to crew for required activities, as well as layout and accommodations within that volume. NASA is looking for innovative methods to unobtrusively collect NHV data without impacting crew time. Data required includes metrics such as location and orientation of crew, volume used to complete tasks, internal translation paths, flow of work, and task completion times. In less constrained environments methods for collecting such data exist yet many are obtrusive and require significant postprocessing. Example technologies used in terrestrial settings include infrared (IR) retroreflective marker based motion capture, GPS sensor tracking, inertial tracking, and multiple camera filmography. However due to constraints of space operations many such methods are infeasible, such as inertial tracking systems which typically rely upon a gravity vector to normalize sensor readings, and traditional IR systems which are large and require extensive calibration. However multiple technologies have not yet been applied to space operations for these explicit purposes. Two of these include 3Dimensional Radio Frequency Identification RealTime Localization Systems (3D RFIDRTLS) and depth imaging systems which allow for 3D motion capture and volumetric scanning (such as those using IRdepth cameras like the Microsoft Kinect or Light Detection and Ranging / LightRadar systems, referred to as LIDAR).
High-authority Piezoelectric Actuation System Synthesis through Mechanical Resonance and Electrical Tailoring

In this research, a new approach is proposed to enhance the effectiveness of piezoelectric actuators. Through mechanical tailoring, the resonant frequencies of the actuation system (this includes the piezoelectric actuator and the related mechanical and electrical elements for actuation) can be tuned to the required actuation frequencies. This obviously will increase the authority (both stroke and force) of the actuation system. However, the resonant actuation system can be hard to control and nonrobust, due to its narrow operating bandwidth. This issue can be resolved through electric circuit tailoring. With the aid of a network of inductance, resistance, and negative capacitance, the actuation resonant peak can be significantly broadened and flattened. In this case, one can achieve a high authority actuation system without the negative effects of resonant problems. The electrical networks can also achieve a fail-safe system due to its passive shunting character. The proposed concept is evaluated using a PZT tube actuator for trailing edge flap control of rotorcraft blades. Promising results are demonstrated, showing that the treatment can indeed create a high-authority and robust actuation system that satisfies the performance requirements of the example application. Also, the proposed concept is verified by experiments using an equivalent circuit model with a synthetic inductor and a negative impedance converter of capacitance.
Stepped-frequency processing by reconstruction of target reflectivity spectrum

This paper describes a processing technique for combining stepped-frequency waveforms efficiently to obtain higher range resolution. Essentially this method involves the reconstruction of a wider portion of the target's reflectivity spectrum by combining the individual spectra of the transmitted narrow-bandwidth pulses in the frequency domain. This paper describes the signal processing steps involved, and shows simulation results which validate and illustrate the method.
3-D Electromagnetic Modeling of Polarization-Dependent Coupling Characteristics of 1×3 Linear Array Weakly Fused Fiber Couplers

Based on the full-wave surface integral equations method and the steplike approximation technique, a three-dimensional (3-D) electromagnetic model for simulating polarization-dependent power-coupling behavior of 1×3 linear array weakly fused fiber couplers is proposed. The accuracy of the proposed numerical model is confirmed to be good by comparing with the measured power transfer behavior at the fusing and elongating process of the couplers. In the 3-D modeling view, the polarization-dependent coupling behavior of two practical couplers, 1/3 power splitter and wavelength-flattened coupler, are numerically studied. It is seen that as the coupler is designed in a very weakly fused condition the polarization-dependent loss (PDL) is significantly increased. For designing the 1×3 coupler with low PDL, it is suggested that the aspect ratio has to be controlled in stronger fused range between 0.8 and 0.9.
The taxonomy of the anopluran genera Polyplax and Eremophthirius, including the description of new species

The anopluran genera Polyplax Enderlein and Eremophthirius Glinkiewicz are very closely related. Together they constitute a natural group of the subfamily Hoplopleurinae, family Haematopinidae, which parasitize exclusively hosts of one family of rodents, the Muridae, and of one family of insectivores, the Soricidae. The group is widely distributed, being found on all continents except Australia. It is best represented in Africa, where 16 species are known.
Experimental Investigation of Low Speed Disc Brake Judder Vibration

Brake judder is defined as disc or drum deformation-induced vibration which typically occurs at frequency less than 200 Hz. There are two types of brake judder namely, low speed (cold) judder and high speed (hot) judder. These two types of judder are often causing the brake pedal, steering wheel, suspension or chassis to vibrate. Consequently, it will affect comfort level of the driver and passengers. This paper focuses on the experimental investigation of low speed brake judder. In doing so, a laboratory test rig consists of disc brake unit, steering and suspension systems was used to assess level of brake judder vibration at different wheel turning angles. It was found that brake judder generated slightly high vibration at the steering wheel in the axial direction which led to a little uncomfortable feeling to the driver.
Determination of the electrical characteristics of Hall plates

The theoretical determination of the electrical behaviour of the Hall plate has hitherto involved difficult computations based on the mathematical technique of conformal transformation.The paper outlines an alternative method of theoretically deriving such electrical characteristics, based on the numerical solution of the finite-difference form of Laplace's equation using a digital computer. The method, while basically simple, is capable of application to Hall plates of any configuration.
Image-Based Localization and Content Authoring in Structure-from-Motion Point Cloud Models for Real-Time Field Reporting Applications

AbstractRecent research efforts to improve information management on construction sites have focused on devising mobile augmented reality methods to provide on-demand access to project information and facilitate field reporting. To track position and orientation of the users, prior research focused on radio frequency based location tracking methods, fiduciary markers, or parallel visual tracking and mapping techniques. These methods have potential in providing fast information access to field personnel, yet their application heavily depends on preinstalled infrastructure, may suffer from accumulated drift errors, and in the case of visual methods do not typically scale well. Furthermore, these methods do not provide content authoring capability in three dimensions, which is necessary for reciprocal application of augmented reality for field reporting and asynchronous personnel-to-personnel communications. To overcome these limitations, this paper presents a scalable markerless and infrastructure-independe.
Inspection on Buckling Mode of Crossed-Rib Reinforced Composite Laminates Panel by Fringe Projection Profilometry

Digital fringe projection profilometry (FPP) is suitable to inspect surface profile of object, with some apparent advantages of non-contact, full-field measurement, simple apparatus, high precision, and real-time profile automation. Four phase-shifted sinusoidal fringe patterns are circularly projected onto the surface of a composite laminates panel reinforced with crossed ribs. Phase shifting method is applied to inspect the surface profile variations during compression. The profile results reveal that different local buckling modes appear at different crossed ribs, where the wave villages locate at the middle and the wave peaks occur at the composite panel ends. From the details of the deflection analysis, it can be seen that the local buckling modes couple with the whole bending of the composite panel. The local buckling modes vary with the applied load and the experimental results are helpful to understand its failure mechanism.

Planning, estimation and productivity in the lean concrete pour

With an increasingly competitive global market, the UK construction industry finally realised that in order to survive, a marked increase in efficiency and effectiveness have to be achieved in all areas. This paper will describe the UK's approach to planning and designing the concrete operations that form a major part of many civil engineering construction projects. A productivity study has been carried out on three different construction projects and over 200 concrete pours have been observed. The data and knowledge collected on site have been subjected to lean construction philosophies, producing a “lean” measure of productivity, and it has been shown that major productivity increases could be achieved by implementing several relatively simple principles.
3.4.2 Research on a Framework for Selecting and Applying Systems Engineering Tools for Australian Small and Medium Enterprises – II

Many of the subsystems developed by the Australian Small and Medium Enterprises (SMEs) are integrated into military systems developed by larger companies. If the SMEs cannot win and sustain defence contracts to develop the subsystems because of their lack of systems capability, then the ability of the Australian Defence to develop and deploy needed systems will be adversely affected. By systems capability it is meant effectual use of sound systems engineering (SE) processes and effective use of SE tools. Unlike most large organisations, many of the Australian SMEs engaging in defence work have not widely employed SE processes and tools in their endeavour. In addition, the SE software tools currently used by the Australian SMEs do not appear to have effectively aided the SMEs in their work. This paper describes a methodology employed in the development of a framework for aiding Australian SMEs in defence work in effectively acquiring and applying SE processes and tools and thereby helping to improve their systems capability. Specifically, the methodology involves a collection and analysis of information, using qualitative grounded theory as the fundamental analysis technique, and NVivo software as the analysis tool. The paper also discusses some preliminary results of the research and future work.
The use of B-field measurements in an airborne time-domain system – Part II: examples in conductive regimes

Explorationists are increasingly concerned with finding more difficult targets such as those under cover. Significant developments in Airborne Electromagnetic (AEM) technology are now providing advanced tools for exploration in these scenarios. Recovering the magnetic field B rather than dB/dt from a towed sensor boosts the response from a high-conductance target, as is readily shown with model calculations. The advantage of B-field data in the presence of noise is illustrated with a GEOTEMDEEPO field example over a known conductive body that is covered by a thick conductive sequence and is difficult to detect from dB/dt data alone.
https://researchopenworld.com/comprehensive-risk-genetic-and-acquired-stratification-for-primary-prevention-of-cad-genetic-risk-of-cad/#

Coronary Artery Disease (CAD) is the number one cause of death in the world. Epidemiologists’ claim 50 percent of CAD is genetic. The identified first genetic risk variant, 9p21, was discovered in 2007, and subsequently, efforts have led to identifying hundreds of genetic risk variants predisposing to CAD. CAD is preventable based on clinical trials showing reduction in conventional risk factors, such as cholesterol, is associated with 30–40 percent reduction in cardiac mortality and events. Statin therapy, which lowers plasma cholesterol, is very safe and effective. About 50 percent of all Americans living a normal lifespan will experience a cardiac event. The challenge is selecting among asymptomatic individuals, the 50 percent who would benefit most from prevention. Conventional risk factors are age-dependent, while genetic risk variants are independent of age, and can be determined anytime from birth on, since one’s DNA does not change in one’s lifetime. Utilizing a microarray containing the genetic risk variants, and DNA from saliva or blood, studies was performed in over 1 million cases and controls. Genetic risk variants were shown to be relatively independent of conventional risk factors and offer greater discriminatory power in stratifying for CAD risk. Individuals with the highest genetic risk score (GRS) had the highest risk for CAD and benefitted most from statin therapy. A recent study employed the genetic risk in a sample size of 55,685 individuals. Those with a high GRS for CAD (20%) had a 91 percent higher risk for cardiac events. Individuals with a healthy lifestyle and high GRS had a 46 percent lower risk for cardiac events in comparison to those with an unfavorable lifestyle thus, genetic risk can be reduced. Utilizing the GRS to risk stratify for primary prevention of CAD will represent a paradigm shift in halting the spread of this pandemic disease.
Simulation of Hydraulic Characteristic of Injecting Cable into Coiled Tubing

In order to control and monitor downhole equipment, it is needed to inject cable into coiled tubing. Being directly against the drawback of the traditional injecting method, a new method of adding pressurized water has been put forward. By using Workbench software, this paper researched the regular pattern that water flow’s pressureaffects cable in coiled tubing after it has various deformations in both entrance and main part of coiled tubing, taking 25mm diameter coiled tubing with 3mm diameter cable as an example. It also simulated the effects of water flow toward cable in coiled tubing as well as how the different diverging distances of entrance for injection affects the speed of cable during injection, taking 50.8mm diameter coiled tubing with 5.6 mm diameter cable as an example. It determined the optimal position of cable entrance and provided the theoretic foundation for the possibility and practical manipulation of the new method for injecting cable into coiled tubing.
