Das griechische Bekenntnis des Akakios von Beroia (CPG 6481) wiederhergestellt
Authors: Kinzig Wolfram 
Published: May 2015

Abstract
The author presents a new reconstruction of most of the Greek text of a confession of faith which has only been preserved in its entirety in a Latin translation ascribed to Acacius of Beroea (ca. 330−433 C.E.; cf. CPG 6481). The extant Greek fragments have come down to us under the name of Amphilochius of Iconium (d. 398/404); they have once again been included in a recent edition of Amphilochius’ work by Michel Bonnet and Sever J. Voicu (Sources Chretiennes, vol. 553). Nonetheless, the present article argues that the Christological passages of the text better fit the situation in the aftermath of the Third Ecumenical Council of 431 and in fact resemble the Christmas sermons delivered by one of Acacius followers, Paul of Emesa, in Alexandria in 432/433.

Published: May 2015

Abstract
The last two books in what has survived of the fourth century biblical manuscript Codex Sinaiticus are the Epistle of Barnabas and the Shepherd of Hermas. This article is an investigation of the correctors’ treatment of the text of the Shepherd of Hermas in this codex, and advances our knowledge at various points of both Codex Sinaiticus and its textual revisions of the Shepherd of Hermas. Furthermore, it attempts to assess the relevance of the corrections for the reception history of the Shepherd of Hermas.

Fischer indolization of the (1,4-phenylenedihydrazono) derivative8gave the polycyclic system9. The Schmidt reaction of2led to the formation of the benzimidazo[1,2-b] [2]benzazepine ring system11. The Mannich reaction of2led to the spirocyclic system15. The reactions of2with aldimines and aromatic aldehydes were also investigated.
Evaluation of Clustering Parameters in WSN Fields Using Distributed Zone-Based Approach
Authors: Prabhu B. , Sophia S. 
Published: May 2015

Abstract
Wireless sensor network (WSN) is a low-powered network formed by the sensor nodes that finds application in civilian, military, visual sense models, and many others. Improved network lifetime is an important task to be achieved by these sensor networks. In this paper, a methodology for evaluation of clustering efficiency, routing efficiency, energy efficiency, and the lifetime of two dense wireless sensor network fields—using a distributed clustering approach, the hybrid energy efficient clustering algorithm (HEECA)—was proposed, which mainly targeted effectively prolonging the lifetime of wireless sensor networks. It is a well-distributed and energy-efficient clustering algorithm that employs three novel techniques: zone based transmission power (ZBTP), routing using distributed relay nodes (DRNs), and rapid cluster formation (RCF). The proposed scheme was compared with two well-evaluated existing distributed clustering algorithms, O-LEACH and HEED. Simulation results clearly showed an excellent improvement in remaining energy, throughput, routing efficiency, and energy efficiency of the entire wireless sensor system. The clustering process was effectively controlled, thereby the number of cluster heads selection and the number of packets delivered to the base station was also found to be effective. Ultimately, the overall lifetime of the wireless sensor network was improved when compared to the two existing distributed clustering algorithms.

Published: May 2015

Abstract
Dobutamine stress echocardiography (DSE) is widely used during follow-up after cardiac transplant for the diagnosis of allograft vasculopathy. We investigated the effect of donor–recipient age difference on the ability to reach target heart rate (HR) during DSE.
All cardiac transplant patients who were undergoing DSE over a 3-year period in a single institution were reviewed. Target HR was specified as 85%×(220–patient age). Further patient and donor demographics were obtained from the local transplant database.
61 patients (45 male, 55±12 years) were stressed with a median dose of 40mcg/kg per min dobutamine. Only 37 patients (61%) achieved target HR. Donor hearts were mostly younger (mean 41±14 years, P<0.001), with only 11 patients (18%) having donors who were older than they were. Patients with older donors required higher doses of dobutamine (median 50 vs 30mcg/kg per min, P<0.001) but achieved a lower percentage target HR (mean 93% vs 101%, P=0.003) than those with younger donors did. Patients with older donors were less likely to achieve target HR (18% vs 67%, P=0.003).
In conclusion, donor–recipient age difference affects the likelihood of achieving target HR and should be considered when a patient is consistently unable to achieve ‘adequate’ stress according to the patient’s age.
XSim: Simulation of Descendants from Ancestors with Sequence Data
Authors: Cheng Hao , Garrick Dorian , Fernando Rohan 
Published: May 2015

Abstract
Real or imputed high-density SNP genotypes are routinely used for genomic prediction and genome-wide association studies. Many researchers are moving toward the use of actual or imputed next-generation sequence data in whole-genome analyses. Simulation studies are useful to mimic complex scenarios and test different analytical methods. We have developed the software tool XSim to efficiently simulate sequence data in descendants in arbitrary pedigrees. In this software, a strategy to drop-down origins and positions of chromosomal segments rather than every allele state is implemented to simulate sequence data and to accommodate complicated pedigree structures across multiple generations. Both C++ and Julia versions of XSim have been developed.
Major Histocompatibility Complex Genes Map to Two Chromosomes in an Evolutionarily Ancient Reptile, the Tuatara Sphenodon punctatus

Published: May 2015

Abstract
Major histocompatibility complex (MHC) genes are a central component of the vertebrate immune system and usually exist in a single genomic region. However, considerable differences in MHC organization and size exist between different vertebrate lineages. Reptiles occupy a key evolutionary position for understanding how variation in MHC structure evolved in vertebrates, but information on the structure of the MHC region in reptiles is limited. In this study, we investigate the organization and cytogenetic location of MHC genes in the tuatara (Sphenodon punctatus), the sole extant representative of the early-diverging reptilian order Rhynchocephalia. Sequencing and mapping of 12 clones containing class I and II MHC genes from a bacterial artificial chromosome library indicated that the core MHC region is located on chromosome 13q. However, duplication and translocation of MHC genes outside of the core region was evident, because additional class I MHC genes were located on chromosome 4p. We found a total of seven class I sequences and 11 class II β sequences, with evidence for duplication and pseudogenization of genes within the tuatara lineage. The tuatara MHC is characterized by high repeat content and low gene density compared with other species and we found no antigen processing or MHC framework genes on the MHC gene-containing clones. Our findings indicate substantial differences in MHC organization in tuatara compared with mammalian and avian MHCs and highlight the dynamic nature of the MHC. Further sequencing and annotation of tuatara and other reptile MHCs will determine if the tuatara MHC is representative of nonavian reptiles in general.

AbstractThe date palm (Phoenix dactylifera L.) is one of the oldest cultivated trees and is intimately tied to the history of human civilization. There are hundreds of commercial cultivars with distinct fruit shapes, colors, and sizes growing mainly in arid lands from the west of North Africa to India. The origin of date palm domestication is still uncertain, and few studies have attempted to document genetic diversity across multiple regions. We conducted genotyping-by-sequencing on 70 female cultivar samples from across the date palm–growing regions, including four Phoenix species as the outgroup. Here, for the first time, we generate genome-wide genotyping data for 13,000–65,000 SNPs in a diverse set of date palm fruit and leaf samples. Our analysis provides the first genome-wide evidence confirming recent findings that the date palm cultivars segregate into two main regions of shared genetic background from North Africa and the Arabian Gulf. We identify genomic regions with high densities of geographically segregating SNPs and also observe higher levels of allele fixation on the recently described X-chromosome than on the autosomes. Our results fit a model with two centers of earliest cultivation including date palms autochthonous to North Africa. These results adjust our understanding of human agriculture history and will provide the foundation for more directed functional studies and a better understanding of genetic diversity in date palm.

Abstract
Rust is a major pathogen of the peanut crop. Development and adoption of rust-resistant cultivars is the most cost efficient and effective way to control the spread of the disease and reduce yield losses. Some cultivated peanut germplasm accessions have a degree of resistance, but the secondary gene pool is a source of much stronger resistance alleles. Wild species, however, have undesirable agronomic traits that are a disincentive to their use in breeding. The identification of genomic regions that harbor disease resistance in wild species is the first step in the implementation of marker-assisted selection that can speed the introgression of wild disease resistances and the elimination of linkage drag. In this work, we identify genome regions that control different components of rust resistance in a recombinant inbred line population developed from a cross between two Arachis species, the susceptible most probable B genome ancestor of cultivated peanut, Arachis ipaënsis, and an accession of its closest relative, Arachis magna, which is resistant to rust. Quantitative trait loci for several components of resistance were placed in the same position on linkage group B08. Single-nucleotide polymorphism Kompetitive allele-specific polymerase chain reaction markers for rust resistance region were designed and validated for marker function in both diploid and tetraploid contexts.

Abstract
We used the animal model in S0 (F1) recurrent selection in a self-pollinating crop including, for the first time, phenotypic and relationship records from self progeny, in addition to cross progeny, in the pedigree. We tested the model in Pisum sativum, the autogamous annual species used by Mendel to demonstrate the particulate nature of inheritance. Resistance to ascochyta blight (Didymella pinodes complex) in segregating S0 cross progeny was assessed by best linear unbiased prediction over two cycles of selection. Genotypic concurrence across cycles was provided by pure-line ancestors. From cycle 1, 102/959 S0 plants were selected, and their S1 self progeny were intercrossed and selfed to produce 430 S0 and 575 S2 individuals that were evaluated in cycle 2. The analysis was improved by including all genetic relationships (with crossing and selfing in the pedigree), additive and nonadditive genetic covariances between cycles, fixed effects (cycles and spatial linear trends), and other random effects. Narrow-sense heritability for ascochyta blight resistance was 0.305 and 0.352 in cycles 1 and 2, respectively, calculated from variance components in the full model. The fitted correlation of predicted breeding values across cycles was 0.82. Average accuracy of predicted breeding values was 0.851 for S2 progeny of S1 parent plants and 0.805 for S0 progeny tested in cycle 2, and 0.878 for S1 parent plants for which no records were available. The forecasted response to selection was 11.2% in the next cycle with 20% S0 selection proportion. This is the first application of the animal model to cyclic selection in heterozygous populations of selfing plants. The method can be used in genomic selection, and for traits measured on S0-derived bulks such as grain yield.

Estimated Number of Infants Detected and Missed by Critical Congenital Heart Defect Screening
Authors: Ailes Elizabeth C. , Gilboa Suzanne M. , Honein Margaret A. , Oster Matthew E. 
Published: May 2015

BACKGROUND AND OBJECTIVES:
In 2011, the US Secretary of Health and Human Services recommended universal screening of newborns for critical congenital heart defects (CCHDs), yet few estimates of the number of infants with CCHDs likely to be detected through universal screening exist. Our objective was to estimate the number of infants with nonsyndromic CCHDs in the United States likely to be detected (true positives) and missed (false negatives) through universal newborn CCHD screening.

METHODS:
We developed a simulation model based on estimates of birth prevalence, prenatal diagnosis, late detection, and sensitivity of newborn CCHD screening through pulse oximetry to estimate the number of true-positive and false-negative nonsyndromic cases of the 7 primary and 5 secondary CCHD screening targets identified through screening.

RESULTS:
We estimated that 875 (95% uncertainty interval [UI]: 705–1060) US infants with nonsyndromic CCHDs, including 470 (95% UI: 360–585) infants with primary CCHD screening targets, will be detected annually through newborn CCHD screening. An additional 880 (UI: 700–1080) false-negative screenings, including 280 (95% UI: 195–385) among primary screening targets, are expected. We estimated that similar numbers of CCHDs would be detected under scenarios comparing “lower” (∼19%) and “higher” (∼41%) than current prenatal detection prevalences.

CONCLUSIONS:
A substantial number of nonsyndromic CCHD cases are likely to be detected through universal CCHD screening; however, an equal number of false-negative screenings, primarily among secondary targets of screening, are likely to occur. Future efforts should document the true impact of CCHD screening in practice.

Authors: Sánchez Alejandro , Guerra Karla Y. , Porta Andrés V. , Orozco Susana 
Published: May 2015

ABSTRACTIn this work, the viscoelastic behavior of a polymeric step-index optical fiber is studied, and the loss factors η of their complex moduli are calculated. The loss factors of the Young and shear moduli were determined from the measurement of the damping ratio γ of a simple pendulum and a torsion pendulum respectively, using the Kelvin-Voigt model of the viscoelastic theory. The shear and Young complex moduli can be used to study the optic-viscoelastic behavior of a polymeric step-index optical fiber.

Published: May 2015

ABSTRACTIn this investigation, the chemical and microstructural characteristics of nanostructured AlFe intermetallic produced by high-energy ball milling have been explored. High purity elemental powders were used as the starting material. The ball milling was carried out at room temperature using a SPEX-8000 mixer/mill. The structure, morphology and compositions of the powders were obtained using X-ray diffraction patterns (XRD), scanning and transmission electron microscopy (STEM). High resolution electron microscopy observations have been used in the nanostructured materials characterization. The structural configurations have been explored through comparisons between experimental HREM images and theoretically simulated images obtained with the multislice method of the dynamical theory of electron diffraction.

Published: May 2015

ABSTRACTPrecise spatial patterns and micro and nanostructures of peptides and proteins have widespread applications in tissue engineering, bioelectronics, photonics, and therapeutics. Optical lithography using proteins provides a route to directly fabricate intricate, bio-friendly architectures rapidly and across a range of length scales. The unique mechanical strength, optical properties, biocompatibility and controllable degradation of biomaterials from silkworms offer several advantages in this paradigm. Here, we present the biochemical synthesis and applications of a “protein photoresist” synthesized from the silk proteins, fibroin and sericin. Using light-activated direct-write processes such as photolithography, we show how silk proteins can form high resolution, high fidelity structures in two and three dimensions. Protein features can be precisely patterned at sub-microscale resolution (µm) at the bench-top over macroscale areas (cm), easily and repeatedly with high-throughput. For instance, periodic, microstructured arrays can be patterned over large areas to form structurally induced iridescent patterns and functional opto-electronic structures. We further demonstrate how photocrosslinked protein micro-architectures can function for the spatial guidance of cells without use of cell-adhesive ligands as biocompatible and biodegradable scaffolds. The ease of biochemical functionalization, biocompatibility, as well as favorable mechanical properties and biodegradation of this silk biomaterial provide opportunities for otherwise inaccessible applications as sustainable, bioresorbable protein microdevices.

Published: May 2015

Abstract
This paper describes the implementation of a methodology for classification of artificial lift system failures and adding a commonly used root cause failure classification from C-Fer (RIFT). The subject field is the oldest Colombian oilfield, which was discovered in 1918, and was produced by primary recovery, then by gas injection as secondary recovery; in the 80's the water flooding project started and finally, in 2006 optimization of water flooding took place increasing production from 4,500 bopd up to 40,000 bopd. Conditions are challenging for all types of artificial lift systems, including sand production, CO2 corrosion, H2S presence, high water cuts and unstable injection conditions.
This methodology was applied to different artificial lift systems, such as: Beam Pump (BP), Progressive Cavity Pumps (PCP), Electrical Submersible Pumping Systems (ESP) and Electrical Submersible Progressive Cavity Pumping Systems (ESPCP). The starting point was the definition or limitation of the boundaries of every system, since some of them use rods for power transmission and others use a power cable. Then, every job in the well was defined as Failure, Failure No-ALS or No Failure in order to classify and look for ways to improve run life and decrease failures by implementing action plans with operations, engineering, and suppliers among others.
The addition of root cause failure classification helped to refine the action plans in order to solve the issues. In some cases, it was necessary to customize RIFT classification in order to track local issues; such as: unstable injection wells, drilling operations in the same well location, etc (some examples are included).
Included in this methodology, some KPIs: failure index, indirect failure index, pulling index, recurrence index, average run life, average run time were used. These KPIs helped track performance improvement in the last two years, getting excellent results.
