We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with a radius of 1.30±0.09 R Jup , a mass of 1.90±0.08 M Jup and an orbital period of 1.401 days. Its host is a Sun-like star, with a G5 spectral type and a mass and radius of 0.98±0.06 M ⊙ and 0.96±0.05 R ⊙ respectively. The proximity of the planet to its host means that WASP-135b receives high levels of insolation, which may be the cause of its inflated radius. Additionally, we find weak evidence of a transfer of angular momentum from the planet to its star.

Value engineering is a basic concept which is generally used in automobile sector to increase the overall production of company and eliminate all unnecessary process so that the profit of a plat can be maximized. In 21th century competition in automobile sector is going to increase day by day. Production and demand of the product is limited for all groups because there is lot of choices available in market for a customer that is way not only the production is increases today but the demand of goods is also increases. So the idea of reducing the total manufacturing cost of running part and also reducing the amount of their wastage such as parts scrap, issue of quality of parts and other reason of rejection of parts i.e. value analysis of parts is to be done so that a group produces the same parts is of cheaper cost from their competitors in market. Over the last decade the interest in standardization of products has been increased. This interest stems from the high technology projects and the overseas business market requirement in the mid-century (1950). The International market leads to competition and its requirement for continuous improvement became an issue of major importance in 1980s and even more important in 1990s. This competitive market required organizations that provide the superior values to the customer. Standardization is important for exchange of goods and services at international level in the world. It is also cooperation in the scientific, technology and economic activities.

Why are large, complex ecosystems stable? Both theory and simulations of current models predict the onset of instability with growing size and complexity, so for decades it has been conjectured that ecosystems must have some unidentified structural property exempting them from this outcome. We show that trophic coherence-a hitherto ignored feature of food webs that current structural models fail to reproduce-is a better statistical predictor of linear stability than size or complexity. Furthermore, we prove that a maximally coherent network with constant interaction strengths will always be linearly stable. We also propose a simple model that, by correctly capturing the trophic coherence of food webs, accurately reproduces their stability and other basic structural features. Most remarkably, our model shows that stability can increase with size and complexity. This suggests a key to May's paradox, and a range of opportunities and concerns for biodiversity conservation.

Sensing via fiber optics has occupied R&D groups for over 40 years, and some important transitions into the commercial sector have been achieved. We look at the fundamental concepts involved in the various sensing approaches, and the differentiators which have led to commercial impact. We also look to the future of fiber-optic sensors.

Although high resolution orthoimages have been the most popular photogrammetric derivative, the cost of orthoimaging production remains high for areas where access is difficult. This paper presents a procedure for a cost effective orthoimage production, from data (digital images, GCPs and DTMs) derived solely from Airborne Laser Scanner systems. ALS systems are designed to produce a highly accurate 3D point cloud, which can be easily rasterized in an accurate, high resolution and dense DEM. Applying a hillshade effect on that dense DEM, one can visualize the objects with great detail and thus measure 3D coordinates for points to be used as GCPs. Modern ALS systems incorporate medium format digital cameras with high resolution imaging abilities. As no ground surveying is needed, the production of high end orthoimages may be performed even in regions that are inaccessible or difficult to access, such as remote islets and mountain tops. A workflow is proposed for the production of orthoimages from low density (2.5 points/m 2 ) laser data using an ALS II-50 system and its medium format RCD105 digital camera. The area of the case study is the northern section of the Greek island Milos. Utilizing automated processes, a series of quality control tasks and a preprocessing of the data is performed. During the data processing, an interpolation of the LiDAR data's first returns is performed, in order to rasterize a high resolution (1m) DEM. The orthorectification process is been performed with the same DEM, leading to an orthoimage with a planimetric accuracy of 1m and minimum geometric distortions. The cost analysis of the applied procedure has proved that the method is less cost demanding compared to the usual orhoimage production methods.

Femtosecond optical pumpÀprobe spectroscopy with 10 fs visible pulses is employed to elucidate the ultrafast carrier dynamics of few-layer MoS 2. A nonthermal carrier distribution is observed immediately following the photoexcitation of the A and B excitonic transitions by the ultrashort, broadband laser pulse. Carrier thermalization occurs within 20 fs and proceeds via both carrierÀcarrier and carrierÀphonon scattering, as evidenced by the observed dependence of the thermalization time on the carrier density and the sample temperature. The n À0.37(0.03 scaling of the thermalization time with carrier density suggests that equilibration of the nonthermal carrier distribution occurs via non-Markovian quantum kinetics. Subsequent cooling of the hot FermiÀDirac carrier distribution occurs on the ∼0.6 ps time scale via carrierÀphonon scattering. Temperature-and fluencedependence studies reveal the involvement of hot phonons in the carrier cooling process. Nonadiabatic ab initio molecular dynamics simulations, which predict carrierÀcarrier and carrierÀphonon scattering time scales of 40 fs and 0.5 ps, respectively, lend support to the assignment of the observed carrier dynamics.

which alternative treatment options are inadequate [3]. ER opioid formulations are taken only once daily or twice daily, compared with every 4-to 6-hour dosing with conventional immediate-release (IR) formulations. However, along with the increased popularity and availability of ER opioid formulations, misuse, abuse, and diversion of these medications has become a significant public health issue in the United States (US) [4-6]. Strategies are therefore needed to address the medical need for pain relief while offering approaches to minimize prescription opioid abuse. One strategy is the development of new drug formulations intended to reduce the attractiveness to abusers and drug-liking qualities of conventional opioid formulations while still providing pain

In the framework of the Medipix collaboration the PCC, a single photon counting pixel chip, has been developed with the aim of improving the contrast resolution in medical imaging applications. The PCC consists of a matrix of 64;64 square pixels with 170 m side length, each pixel comprising a 15-bit counter and a pulse-height discriminator. The chip has been bump bonded to equally segmented 200 m thick SI-LEC GaAs detectors showing a very high absorption energy for X-rays used in diagnostics. An absolute calibration of the system with a radioactive source and a synchrotron beam are described resulting in the value of the test input capacitance of &24.7 fF. Using this value a full characterisation of the system from electrical measurements is presented. The entire system can reach a minimum threshold of &2100e\ with &250e\ rms noise. One of the characteristic features of the PCC is the possibility to adjust the thresholds of all pixels on a pixel-by-pixel basis with 3-bit precision. The threshold distribution after adjustment is &120e\ rms. The spatial resolution of the system has been measured to be 3.6 lp/mm. A comparison of a tooth image taken with the PCC and with a screen-CCD-system demonstrates its imaging capabilities.

Nanowire-based THz detection Terahertz (THz) radiation is an interesting region of the electromagnetic spectrum lying between microwaves and infrared. Non-ionizing and transparent to most fabrics, it is finding application in security screening and imaging but is also being developed for communication and chemical sensing. To date, most THz detectors have focused just on signal intensity, an effort that discards half the signal in terms of the full optical state, including polarization. Peng et al. developed a THz detector based on crossed nanowires (arranged in a hash structure) that is capable of resolving the full state of the THz light. The approach provides a nanophotonic platform for the further development of THz-based technologies. Science , this issue p. 510

We demonstrate the feasibility of a thermal imprint technology capable of structuring organic thin films with liquid crystalline properties forming feature sizes on a several micrometer scale. The imprint technique can directly be applied onto a variety of substrates including dielectric mirrors. The so fabricated three-dimensional microcavities have lateral extensions up to 20 µm and heights between 1 and 5 µm. Exemplarily, pillar microcavities were produced wherein three-dimensional photonic confinement is observed by the formation of 0D cavity mode patterns. The imprint technique further favors the formation of hemispherical pillar geometries rather than cylindrical pillars resulting in equidistant mode spacings of transversal cavity modes.

Optical coherence tomography (OCT) imaging at 1060 nm region proved to be a successful alternative in ophthalmology not only for resolving intraretinal layers, but also for enabling sufficient penetration to monitor the sub-retinal vasculature in the choroids when compared to most commonly used OCT imaging systems at 800 nm region. To encourage further clinical research at this particular wavelength, we have developed a compact fiber optic source based on amplified spontaneous emission (ASE) centered at ~1060 nm with ~70 nm spectral bandwidth at full-width half maximum (FWHM) and output power >20 mW. Our approach is based on a combination of slightly shifted ASE emission spectra from a combination of two rare-earth doped fibers (Ytterbium and Neodymium). Spectral shaping and power optimization have been achieved using in-fiber filtering solutions. We have tested the performances of the source in an OCT system optimized for this wavelength.

The three-and four-site-correlation functions in a two-dimensional Ising-Peierls square lattice gas are computed by means of the cluster variation method (CVM) introduced by Kikuchi. The non-linear CVM equations are numerically solved and the values of several multi-site correlation functions are compared with the results of Monte Carlo simulations at four different coverages (0-1113 ~, ~, 5, ~) as functions of the lateral coupling flJ. The results obtained by CVM are accurate within few percent at all coverages and lateral couplings taken into account. Thus the CVM results are used as a basis for a discussion of the validity of the Kirkwood superposition approximation in lattice gases.

The purpose of this research paper is to examine the increasing reality of global supply chain disruptions experienced by industries worldwide and how these disruptions can be managed. Three recent disruptions that occurred in three different industries were explored and the findings show that supply chain disruption strategies were divided into proactive strategies, before a disruption has happened, and reactive strategies, after a disruption has occurred. These strategies were used, to varying degrees, in the selected cases.

Microalgae have become an attractive natural source of a diverse range of biomolecules, including enzymatic and non-enzymatic antioxidants; nevertheless, economically sustainable production of such compounds from microalgae biomass is still challenging. The main hurdles are: (a) increasing microalgae yield; (b) achieving optimal cultivation conditions; (c) energy-efficient and cost-effective downstream processing (extraction and purification); (d) optimal storage of post-processed antioxidant molecules. This review provides a detailed overview of enzymatic and non-enzymatic antioxidants in the cellular metabolism of the commercially important microalgae Dunaliella, industrial applications of antioxidant enzymes, strategies to enhanced antioxidant accumulation in cells, and the opportunities and limitations of current technologies for antioxidant enzymes production from microalgae biomass as an alternative to common microbial sources.

A method for the remote detection and identification of liquid chemicals at ranges of tens of meters is presented. The technique uses pulsed indirect photoacoustic spectroscopy in the 10-microm wavelength region. Enhanced sensitivity is brought about by three main system developments: (1) increased laser-pulse energy (150 microJ/pulse), leading to increased strength of the generated photoacoustic signal; (2) increased microphone sensitivity and improved directionality by the use of a 60-cm-diameter parabolic dish; and (3) signal processing that allows improved discrimination of the signal from noise levels through prior knowledge of the pulse shape and pulse-repetition frequency. The practical aspects of applying the technique in a field environment are briefly examined, and possible applications of this technique are discussed.

Graphene has already become an established medium for novel photonic devices and their applications. In some cases, e.g. the use of graphene as a non-linear medium with saturable absorption properties, it is experimentally convenient to use the readily available form that is known as graphene oxide. Moreover, technological and scientific developments that are advancing control of the properties of graphene for electronic applications are also likely to be applicable in photonic and optoelectronic devices. This presentation will review research in the field of graphene photonics across the world. It will address, in particular, its application as a saturable absorber, e.g. for pulsed operation of fibre lasers-as well as work on materials characterisation of deposited graphene films. Patterning of graphene films with precision at the microand nano-scales will be an important requirement-and will be considered in this presentation.

A NNLO analysis of certain logarithmic expansions, developed for precision studies of the evolution of the QCD parton distributions (pdf) at the Large Hadron Collider, is presented. We elaborate on their relations to all the solutions of the DGLAP equations that have been hitherto obtained from Mellin space, to which are equivalent. Exact expansions, equivalent to exact solutions of the equations, are constructed in the non-singlet sector. The algorithmic features of our approach are also emphasized, since this method allows to obtain numerical solutions of the evolution equations with the same accuracy of other methods, based on Mellin space, and of brute force methods, which solve the equations by finite differences. The implementation of our analysis allows to compare with existing benchmarks for the evolution of the pdf's, useful for applications at the LHC, and to extend them significantly in a systematic fashion, especially when solutions that retain logarithmic correction...

A general theory for collective diffusion in interacting lattice-gas models is presented. The theory is based on the description of the kinetics in the lattice gas by a master equation. A formal solution of the master equation is obtained using the projection-operator technique, which gives an expression for the relevant correlation functions in terms of continued fractions. In particular, an expression for the collective dynamic structure factor S c is derived. The collective diffusion coefficient D c is obtained from S c by the Kubo hydrodynamic limit. If memory effects are neglected (Darken approximation), it turns out that D c can be expressed as the ratio of the average jump rate and of the zero-wavevector static structure factor S(0). The latter is directly proportional to the isothermal compressibility of the system, whereas is expressed in terms of the multisite static correlation functions gn. The theory is applied to two-dimensional lattice systems as models of adsorbates ...
