EXPLORANDO LA VARIABILIDAD MORFOMÉTRICA DEL CONJUNTO DE CAMÉLIDOS PEQUEÑOS DURANTE EL ARCAICO TARDÍO Y EL FORMATIVO TEMPRANO EN QUEBRADA TULÁN, NORTE DE CHILE / Exploring the morphometric variability of lesser camelids from Quebrada Tulán (northern Chile)

Frecuentemente en el registro arqueofaunistico de sitios arqueologicos ubicados en la vertiente occidental de la puna de Atacama, es posible diferenciar un conjunto de camelidos grandes y otro de menor tamano. En general, el grupo de camelidos grandes ha recibido mayor atencion, existiendo un escaso conocimiento del grupo de tamano mas pequeno. En este trabajo se explora el conjunto de camelidos pequenos a traves de la utilizacion de metodos osteometricos. Por una parte, se consideran colecciones actuales de alpacas y vicunas en las que se analizan las distintas variables que pudiesen estar incidiendo en la variabilidad de los conjuntos. Se otorga especial enfasis a la diferenciacion entre falanges anteriores y posteriores, variacion interespecifica y dimorfismo sexual. Por otra parte, se analizan las primeras falanges de los sitios Tulan-52 (Arcaico Tardio ca. 4500-3800 A.P.) y Tulan-54 (Formativo Temprano ca. 3200-2300 A.P.) con el fin de caracterizar la variabilidad que presentan los conjuntos a traves del tiempo, mediante la comparacion de los resultados del analisis de muestras actuales y arqueologicas. Ambos conjuntos arqueofaunisticos son muy similares a pesar de las diferencias temporales. Los especimenes analizados corresponderian a vicunas, lo que denotaria la importancia de la caza de la vicuna a traves del tiempo. Palabras clave:arqueofaunas,osteometria, alpacas, vicunas Abstract Frequently, it is possible to differentiate among large and small size camelids when analysing registers from archaeological sites located at the occidental slope of Puna de Atacama. However, larger animals have received most of the attention having less knowledge about the group of small size camelids. In this paper and by using osteometric methods we study this small size later group. On one hand, we analyse different variables that may affect variability among modern alpacas and vicunas collections. We focus our work on differences among anterior and posterior phalanxes, inter specific variation and sexual dimorphism. On the other hand, we analyse first phalanxes from Tulan-52 (Late Archaic ca. 4500-3800 BP) and Tulan-54 (Early Formative ca. 3200-2300 BP) characterising their variability through time by comparing current and archaeological samples. Both archaeofaunal assemblages are similar despite their temporal distance. The analyzed specimens correspond to vicunas denoting the importance of vicuna hunting through time.

Evolution of

The ferredoxin family, present in bacteria, algae, higher plants and animals, consists of a diverse range of small, soluble iron sulphur (FeS) proteins, which are characterised by their acidity and low redox potentials. Ferredoxins act as electron acceptors (e.g. for photosynthesis) and donors (e.g. for sulphur and nitrogen assimilation, biosynthesis of chlorophyll, phytochromes and fatty acids) and participate in redox signalling (Fukuyama 2004; Hanke and Mulo 2013; Hemschemeier and Happe 2011). Green microalgae contain multiple plant-type (2Fe2S) ferredoxin isoforms (Yang et al. 2015). However, ferredoxin 1 (FDX1), more commonly known as PETF, is the most studied ferredoxin due to its essential role as the first stromal electron acceptor in the photosynthetic electron transport chain, where it transfers electrons from photosystem I (PSI) to a number of proteins. The principal redox partner of PETF is the ferredoxin-NADP+ oxidoreductase (FNR), which catalyses the production of NADPH from NADP+ and protons (Shin 2004; Winkler et al. 2009). In green microalgae, an electron acceptor of PETF of both biological and biotechnological interest is the [FeFe]hydrogenase, HYDA, which catalyses the production of molecular hydrogen (H2) from protons and electrons. The Abstract Ferredoxins are soluble iron sulphur proteins which function as electron donors in a number of metabolic pathways in a broad range of organisms. In photosynthetic organisms, PETF, or ferredoxin 1 (FDX1), is the most studied ferredoxin due to its essential role in photosynthesis, where it transfers electrons from photosystem I to ferredoxin-NADP+ oxidoreductase. However, PETF can also transfer electrons to a large number of other proteins. One important PETF electron acceptor found in green microalgae is the biologically and biotechnologically important [FeFe]-hydrogenase HYDA, which catalyses the production of molecular hydrogen (H2) from protons and electrons. The interaction between PETF and HYDA is of considerable interest, as PETF is the primary electron donor to HYDA and electron supply is one of the main limiting factors for H2 production on a commercial scale. Although there is no three dimensional structure of the PETF–HYDA complex available, protein variants, nuclear magnetic resonance titration studies, molecular dynamics and modelling have provided considerable insight into the residues essential for forming and maintaining the interaction. In this review, we discuss the most recent findings with
Effects of Salinity on the Morphology of the ' Bursa Siyahı ' , Fig ( Ficus carica L . ) cultivar In vitro Conditions

The objective of this study was to examine the effects of NaCl on the morphology of Ficus carica cv. 'Bursa Siyahı' seedlings. For the salt stress tolerance, seeds of Ficus carica L. cv 'Bursa Siyahı' were germinated in vitro conditions and obtained seedlings were cultured in Murashige and Skoog culture medium without NaCl (as control) and with different NaCl concentrations. It was observed that plant viability were decreased with increasing NaCl concentration in the medium At the end of six weeks, plants were evaluated for the parameters of fresh weight (FW), shoot length (SL), leaf number (LN), root number (RN) and root length (RL). Plants in medium with 40 mM NaCl gave the maximum growth, salt stress effect was found to be increased in relative to the salt concentrations.

Improved total variation-based CT image reconstruction applied to clinical data

In computed tomography there are different situations where reconstruction has to be performed with limited raw data. In the past few years it has been shown that algorithms which are based on compressed sensing theory are able to handle incomplete datasets quite well. As a cost function these algorithms use the ℓ1-norm of the image after it has been transformed by a sparsifying transformation. This yields to an inequality-constrained convex optimization problem. Due to the large size of the optimization problem some heuristic optimization algorithms have been proposed in the past few years. The most popular way is optimizing the raw data and sparsity cost functions separately in an alternating manner. In this paper we will follow this strategy and present a new method to adapt these optimization steps. Compared to existing methods which perform similarly, the proposed method needs no a priori knowledge about the raw data consistency. It is ensured that the algorithm converges to the lowest possible value of the raw data cost function, while holding the sparsity constraint at a low value. This is achieved by transferring the step-size determination of both optimization procedures into the raw data domain, where they are adapted to each other. To evaluate the algorithm, we process measured clinical datasets. To cover a wide field of possible applications, we focus on the problems of angular undersampling, data lost due to metal implants, limited view angle tomography and interior tomography. In all cases the presented method reaches convergence within less than 25 iteration steps, while using a constant set of algorithm control parameters. The image artifacts caused by incomplete raw data are mostly removed without introducing new effects like staircasing. All scenarios are compared to an existing implementation of the ASD-POCS algorithm, which realizes the step-size adaption in a different way. Additional prior information as proposed by the PICCS algorithm can be incorporated easily into the optimization process.

Caring for the Carers

The last century has accustomed us to consider care and technology as two opposing concepts. We are told that care is about affectivity and empathy, while technology is cold and rational. And yet, as Annemarie Mol explains, all care practices use technological tools (1). Rather than imagining care as an innate faculty, therefore, we could begin to see it as a set of techniques and skills acquired in relation to the tools at our disposal.
Influence of Firm Financial Characteristics on Leverage of Non-Financial Listed Companies in Nairobi Securities Exchanges

Listed and non-listed institutions are always in need of finances geared towards enhancing their firm performance which has a pivotal role in the relationship they will enjoy internally and externally. The ability of an organization to invest borrowed capital on projects with a higher return on investment has a significant impact on shareholders wealth maximization. Panel regression modelling revealed the positive influence of firm size and profitability and inverse influence of tangibility and growth opportunities on the leverage of listed non-financial companies in Nairobi securities exchanges.
Approaches to Extractive Text Summarization : A Study

Due to the vast availability of information online, the need for tools to present a concise and abridged version of the source is more than ever before. This has necessitated the research in the field of Automatic Text Summarization. Research in this field began more that 50 years ago with Luhn’s seminal paper on automatic summarization. Since then the problem has been addressed using varying techniques, in different domains and from various perspectives. This paper presents an overview of some of the approaches in the area of Extractive Text Summarization. We explore the different traditional efforts in sentence extraction as well as the most novel recent approaches for determining important content.
Data and text mining PROTERAN : animated terrain evolution for visual analysis of patterns in protein folding trajectory

Summary:Themechanismof protein folding remains largely amystery in molecular biology, despite the enormous effort from many groups in the past decades. Currently, the protein folding mechanism is often characterized by calculating the free energy landscape versus various reaction coordinates such as the fraction of native contacts, the radius of gyration and so on. In this paper, we present an integrated approach towardsunderstanding the folding process via visual analysis of patterns of these reaction coordinates. The three disparate processes (1) protein folding simulation, (2) pattern elicitation and (3) visualization of patterns, work in tandem. Thus as the protein folds, the changing landscape in the pattern space can be viewed via the visualization tool, PROTERAN, a program we developed for this purpose. We first present an incremental (on-line) trie-based pattern discovery algorithm to elicit the patterns and then describe the terrain metaphor based visualization tool. Using two example small proteins, a b-hairpin and a designed protein Trp-cage, we next demonstrate that this combined pattern discovery and visualization approach extracts crucial information about protein folding intermediates andmechanism.

Explaining the Cross-Section of Stock Returns in Japan: Factors or Characteristics?

Japanese stock returns are even more closely related to their book-to-market ratios than are their U.S. counterparts, and thus provide a good setting for testing whether the return premia associated with these characteristics arise because the characteristics are proxies for covariance with priced factors. Our tests, which replicate the Daniel and Titman (1997) tests on a Japanese sample, reject the Fama and French (1993) three-factor model but fails to reject the characteristic model.
Load and Attentional Bayes

Selective attention is a most intensively studied psycholo gical phenomenon, rife with theoretical suggestions and schisms. A critical idea i s that of limited capacity, the allocation of which has produced continual conflict abou t such phenomena asearly and late selection. An influential resolution of this debate is based on the notion of perceptual load (Lavie, 2005), which suggests that low-load, easy tasks, because they underuse the total capacity of attentio n, mandatorily lead to the processing of stimuli that are irrelevant to the current attentional set; whereas high-load, difficult tasks grab all resources for themselve s, l aving distractors high and dry. We argue that this theory presents a challenge to Bay esian theories of attention, and suggest an alternative, statistical, accou nt of key supporting data.

Oceanographic research vessels are platforms to carry out acoustic surveys to assess pelagic fisheries resources, using scientific echosounders like Simrad EK60. The quantitative use of echosounder’s data requires a precise determination of background noise since a good signal to noise ratio (SNR) is determinant to have an accurate estimation of fishery resources. This paper presents a new systematical analysis of noise test results method. Three different research vessels (R/V) have been analyzed proving that only 18 and 38 kHz frequencies are influenced for vessel’s propeller system.
Mare volcanism: Reinterpretation based on Kaguya Lunar Radar Sounder data

The Lunar Radar Sounder (LRS) onboard Kaguya (SELENE) detected widespread horizontal reflectors under some nearside maria. Previous studies estimated that the depths of the subsurface reflectors were up to several hundreds of meters and suggested that the reflectors were interfaces between mare basalt units. The comparison between the reflectors detected in the LRS data and surface age maps indicating the formation age of each basalt unit allows us to discuss the lower limit volume of each basalt unit and its space and time variation. We estimated volumes of basalt units in the ages of 2.7 Ga to 3.8 Ga in the nearside maria including Mare Crisium, Mare Humorum, Mare Imbrium, Mare Nectaris, Mare Serenitatis, Mare Smythii, and Oceanus Procellarum. The lower limit volumes of the geologic units estimated in this study were on the order of 103 to 104 km3. This volume range is consistent with the total amount of erupted lava flows derived from numerical simulations of thermal erosion models of lunar sinuous rille formation and is also comparable to the average flow volumes of continental flood basalt units formed after the Paleozoic and calculated flow volumes of Archean komatiite flows on the Earth. The lower limits of average eruption rates estimated from the unit volumes were on the order of 10−5 to 10−3 km3/yr. The estimated volumes of the geologic mare units and average eruption rate showed clear positive correlations with their ages within the same mare basin, while they vary among different maria compared within the same age range.
Infrared imaging simulation and detection of ship wake

The thermal wake would be formed owing to the cooling water or exhaust heat discharged by ship, and the cold wake could be formed by the cool water in the lower part of sea stirred up by the ship propeller or vortexes. Owing to the difference of surface temperature and emissivity between the ship wake and the surrounding ocean the ship wake will be easily detected by the infrared detecting system. The wave of wake also could be detected by the difference of reflected radiance between the background and the Kelvin wake of ship. In this paper the simulating models of infrared imaging of ship wake are developed based on the selfradiation of wake, the reflected radiance of the sky and sun and the transmitted radiance of atmosphere, and the infrared imaging signatures of ship wake are investigated. The results show that the infrared imaging signatures of ship wake can be really simulated by the models proposed in this paper. The effects of the detecting height, the angle of view, the NETD of detector and the temperature of wake on the infrared imaging signatures of ship wake are studied. The temperature difference between the ship wake and surrounding ocean is a main fact which effects on the detecting distance. The infrared imaging signatures of ship wake in 8-14μm wave band is stronger than that in 2-5μm wave band whenever the temperature of ship wake is warmer or cooler than the surrounding ocean. Further, the infrared imaging of thermal wake is investigated in the homogenous water and temperature stratified water at different speed of a ship and different flow rate and depth of the discharged water in a water tank. The spreading and decaying laws of infrared signature of ship wake are obtained experimentally. The results obtained in this paper have an important application in the infrared remote sensing of ship wake.
The impact of ground‐based glaciogenic seeding on clouds and precipitation over mountains: A case study of a shallow orographic cloud with large supercooled droplets

This paper examines the impact of ground‐based glaciogenic seeding on a shallow, lightly precipitating orographic cloud with rather large (~35 µm) supercooled droplets. The storm was observed on 22 February 2012 as part of the AgI (silver iodide) Seeding Cloud Impact Investigation experiment in Wyoming. The cloud base (top) temperature was about −5°C (−12°C). Vertical velocity data from an airborne Doppler W‐band (3 mm) profiling Wyoming Cloud Radar (WCR) indicate broad ascent due to the strong wind (20 m s‐1) impinging on the terrain and small pockets of intense updrafts. The large droplets, low droplet and ice particle concentrations, and strong updrafts lead to natural snow growth mainly by accretion (riming). The treated (seeded) period is compared with the preceding untreated period. The main target site, located on a mountain pass, was impacted by AgI seeding, according to a trace chemistry analysis of the falling snow. Data from three radar systems were used in the analysis of the impact of seeding on snow growth: the WCR, two Ka‐band (1.2 cm) profiling Micro Rain Radars , and an X‐band (3 cm) scanning polarization Doppler‐on‐Wheels radar. This case is complicated somewhat by a natural increase in cloud liquid water and in snow growth by riming, starting halfway during the seeding period, and continuing after seeding ended. Composite data from the centimeter‐wave radar systems indicate an increase in low‐level reflectivity during seeding, even after accounting for the natural trend observed in the upwind control region. A precipitation particle probe at the main target site shows an increase in concentration of both small and large hydrometeors.

This document presents a search for a $W'$ boson, decaying to a top quark and a $b$ quark in an effective coupling approach, using a multivariate method based on boosted decision trees. It reports exclusion limits on the $W'\rightarrow tb$ cross-section times branching ratio and effective couplings as a function of the $W'$-boson mass. The search covers $W'$-boson masses between 0.5 and 3.0 TeV, for right-handed or left-handed $W'$-boson, with 20.3 fb$^{-1}$ of proton-proton collision data produced by the LHC in 2012, at a center-of-mass energy of 8 TeV and collected by the ATLAS detector.
Comment on: Saisho et al. β-Cell Mass and Turnover in Humans: Effects of Obesity and Aging. Diabetes Care 2013;36:111–117

In the article by Saisho et al. (1), the effect of obesity on β-cell mass and turnover was addressed by indirectly estimating β-cell mass from human pancreatic specimens after death related to disease or trauma. Although these results are consistent with the direct measurement of islet volume after isolation from abruptly deceased healthy organ donors, the correlation between β-cell mass and BMI remains weak ( r ≤ 0.5) (2,3). The authors admit that cross-sectional studies provide limited information on the mechanisms that potentially link obesity with this increased (50%) β-cell mass. Rather unexpectedly, for example, no measurable difference in β-cell …
Examining Internet addiction and general health and well being among youth in Taiwan

With rapid advances in the Internet and related technologies, the use of the Internet on school campuses and in society has increased dramatically in recent years. Internet has become an important part of student life and the use of Internet in academic settings is primarily intended for learning and research purposes. However, from time to time, cases of overinvolvement with the Internet have been observed on different campuses in Taiwan. This raises a concern in academicians that Internet addiction may worsen among adolescents and youths due to the rising dependency on the Internet. Further, compulsive Internet is considered as the main cause of poor sleep quality and neglecting work. Therefore, it has become crucial to evaluate the relationships between Internet addiction, sleep quality, and general health and well-being. Within this context, the purpose of this study is to examine the mediating effects of sleep quality on the relationship between Internet addiction and general health and well-being among adolescents and youths. Using an online survey, the data was collected from 300 adolescents and youths in Taiwan. The results indicated that sleep quality mediated 21.71% of the indirect effects of Internet addiction on general health and well-being. The mediation effect was statistically significant which goes to show that sleep quality does have an impact on general health and well-being due to Internet addiction. From the practical point of view, the results of the current study will help the Taiwan government, academicians, health authorities, and planners design appropriate and effective interventions to create more awareness in adolescents and youth to mitigate Internet addiction.
