Published: May 2014

AbstractThe bristle worm Platynereis dumerilii displays many interesting biological characteristics. These include its reproductive timing, which is synchronized to the moon phase, its regenerative capacity that is hormonally controlled, and a slow rate of evolution, which permits analyses of ancestral genes and cell types. As a marine annelid, Platynereis is also representative of the marine ecosystem, as well as one of the three large animal subphyla, the Lophotrochozoa. Here, we provide an overview of the molecular resources, functional techniques, and behavioral assays that have recently been established for the bristle worm. This combination of tools now places Platynereis in an excellent position to advance research at the frontiers of neurobiology, chronobiology, evo-devo, and marine biology.
High-Temperature Electromechanical Properties of CTGS
Authors: Schulz Michal , Fritze Holger , Johnson Ward L. 
Published: May 2014

ABSTRACTCTGS (Ca3TaGa3Si2O14) is a commercially available, Czochralski-grown piezoelectric material from the langasite family that has an ordered crystal structure. It can be excited piezoelectrically up to at least 1285 °C, which is very close to the melting temperature of 1350 °C. In order to determine the loss at elevated temperatures, two different resonance techniques are used. A contactless transduction method is employed up to about 600 °C, whereas transduction involving standard keyhole-shaped film electrodes is employed up to 1285 °C. Comparison of the temperature-dependent inverse Q factor shows that contactless measurements are best suited for the lower temperature range, where sample clamping and losses caused by the electrodes contribute significantly to the total loss. However, at higher temperatures, measurement of the electrical impedance of samples with film electrodes in the vicinity of the resonance frequency proves to be suitable. Even at 1100 °C, 5 MHz CTGS resonators are found to have a Q factor of about 1200, which is great enough to enable numerous bulk-acoustic-wave applications. Further, a nearly linear temperature dependence of the resonance frequency with a temperature coefficient of 210 Hz/K makes Y-cut CTGS well suited for temperature-sensing applications.
In-situ analysis of chemical expansion and stability of SOFC cathodes
Authors: Dragan Mirela , Misture Scott 
Published: May 2014

ABSTRACTIn this work high-temperature X-ray diffraction has been used to investigate thermal and chemical expansion as well as overall phase stability for various cathode materials: Ba0.5Sr0.5Co0.8Fe0.2O3 (BSCF), La0.3Sr0.7CoO3 (LSC37), La0.6Sr0.4CoO3 (LSC64) and La0.6Sr0.4Fe0.8Co0.2O3 (LSCF), as a function of temperature in reducing conditions. When perovskites materials are under a low oxygen partial-pressure condition, the lattice parameter and overall dimension increase. Their chemical expansion has comparable values. From the viewpoint of the stability of these phases, the high-temperature X-ray diffraction results indicate no phase decomposition can be one of the reasons for material failure at the current experimental oxygen partial pressure. LSF is most stable, while LSC and LSCF form oxygen vacancy-ordered phases and then decompose when heated to 1000°C under atmospheres with pO2 as low as 10-5 atm.

ABSTRACTThe influence of oxygenation in the magnetism, superconductivity and electronic states for the Mo0.3Cu0.7Sr2RECu2Oy (RE = Y, Er and Tm) compounds are discussed here. The magnetic measurements on the as-prepared (AP) samples suggest the existence of short-range magnetic correlations due to the presence of the paramagnetic MoV cations in the copper chain site. On the other hand, all the oxygenated samples are not magnetic but superconducting. The high pressure oxygenated sample shows the highest superconducting transition temperature of TC = 84 K. The influence of oxygenation in the electronic states for the Mo0.3Cu0.7Sr2YCu2Oy system associated with an oxidation reaction leading from a non-superconducting to a superconducting state has also been investigated by means of X-ray photoelectron spectroscopy (XPS). XPS measurements show the predominance of the MoV oxidation state over the MoVI one in the AP material; annealing under flowing oxygen enhances both the MoVI and CuII amounts. A detailed study of the electronic states for the Mo0.3Cu0.7Sr2YCu2Oy samples has been performed and is also discussed.

Published: May 2014

ABSTRACTSelf–assembly of molecular building blocks provides an interesting route to produce well-defined chemical structures. Tailoring the functionalities on the building blocks and controlling the time of self-assembly could control the properties as well as the structure of the resultant patterns. Spontaneous self-assembly of biomolecules can generate bio-interfaces for myriad of potential applications. Here we report self-assembled patterning of human serum albumin (HSA) protein in to ring structures on a polyethylene glycol (PEG) modified gold surface. The structure of the self-assembled protein molecules and kinetics of structure formation entirely revolved around controlling the nucleation of the base layer. The formation of different sizes of ring patterns is attributed to growth conditions of the PEG islands for bio-conjugation. These assemblies might be beneficial in forming structurally ordered architectures of active proteins such as HSA or other globular proteins.

Published: May 2014

Objective Children with cleft lip and palate or cleft palate only have a high incidence of conductive hearing loss from otitis media with effusion. Studies demonstrating longitudinal results are lacking. This study was undertaken to investigate long-term longitudinal hearing outcomes of children with cleft lip and/or cleft palate and cleft palate only. Design Retrospective chart review. Setting Clinical charts of patients born with cleft lip and palate or cleft palate only in 1985 to 1994 who were referred to the cleft team in Bergen, Norway. Study findings include 15 years of follow-up. Participants The study population consisted of 317 children of whom 159 had nonsyndromic cleft lip and palate and 158 had nonsyndromic cleft palate. Main Outcome Measures Pure tone average calculated from pure tone audiometry at ages 4, 6, and 15 years. Results The median pure tone average significantly improved with increasing age. For the cleft lip and palate group, the median pure tone average at ages 4, 6, and 15 years was 16 dB hearing level (HL), 13 dB HL, and 9 dB HL, respectively ( P ≤ .001). In the cleft palate group the median pure tone average at ages 4, 6, and 15 years was 15 dB HL, 12 dB HL, and 9 dB HL, respectively ( P ≤ .001). There was no significant difference in the hearing levels between the two groups. Patients who had surgical closure of the palate at age 18 months had a significantly better pure tone average outcome at age 15 compared with patients who had surgery at 12 months. Conclusions Hearing improves significantly from childhood to adolescence in patients with cleft lip and palate and cleft palate only.

Objective To determine the prevalence of cardiac, cervical spine, and carotid artery abnormalities in patients with 22q11.2 deletion syndrome (22q11.2DS) undergoing surgery for velopharyngeal dysfunction (VPD), associations between the presence of these abnormalities, and whether these abnormalities caused changes in surgical management or perioperative complications. Design Retrospective review. Setting Tertiary pediatric hospital. Patients Seventy patients with 22q11.2DS with complete preoperative cervical vascular and spine imaging and cardiac evaluation between 1998 and 2011. Main Outcome Measures Incidence of cardiac, cervical spine, and vascular abnormalities; related perioperative complications; and resulting changes in surgical, anesthetic, or perioperative management plan. Results Cardiac abnormalities occurred in 45 patients (64.3%), and 8 patients required cardiac anesthesia. Thirty-eight patients (54.3%) had at least one vascular abnormality of the neck, and 14% had medial deviation of the internal carotid artery. Surgery was not performed in one patient, and the surgical plan was altered in three patients because of carotid anomalies. Cervical spine abnormalities were found in 24 patients (34.3%); 8 patients demonstrated radiographic evidence of cervical instability and were treated with spinal precautions during surgery. The presence of one anomaly was not predictive of any other finding, and there were no complications related to the heart, cervical spine, or carotid arteries. Conclusions Anomalies of the heart, cervical spine, and cervical vasculature occur frequently in 22q11.2DS, vary drastically in severity, and are impossible to predict based on other features of the syndrome. Preoperative diagnosis of these comorbidities with routine imaging can minimize the risk of avoidable surgical complications.

Abstract
Extraordinary advancements in sequencing technology have made what was once a decade-long multi-institutional endeavor into a methodology with the potential for practical use in a clinical setting. We therefore set out to examine the clinical value of next-generation sequencing by enrolling patients with incurable or ambiguous tumors into the Personalized OncoGenomics initiative at the British Columbia Cancer Agency whereby whole genome and transcriptome analyses of tumor/normal tissue pairs are completed with the ultimate goal of directing therapeutics. First, we established that the sequencing, analysis, and communication with oncologists could be completed in less than 5 weeks. Second, we found that cancer diagnostics is an area that can greatly benefit from the comprehensiveness of a whole genome analysis. Here, we present a scenario in which a metastasized sphenoid mass, which was initially thought of as an undifferentiated squamous cell carcinoma, was rediagnosed as an SMARCB1-negative rhabdoid tumor based on the newly acquired finding of homozygous SMARCB1 deletion. The new diagnosis led to a change in chemotherapy and a complete nodal response in the patient. This study also provides additional insight into the mutational landscape of an adult SMARCB1-negative tumor that has not been explored at a whole genome and transcriptome level.

AbstractThe main goal of this study is a better knowledge of the deformation and sedimentary evolution of the southwestern part of the Paris basin, a low subsiding domain, at the transition between the Paris and Aquitaine basins. This study is based on the analysis of industrial seismic lines reprocessed by the BRGM (French Geological Survey), calibrated on petroleum wells, water supply wells (coming from the BSS, BRGM database) and outcrops.Four second order (10 Ma and multiples) transgressive-regressive cycles were defined on facies evolution on dated sediments. There are similar to those defined in the central part of the Paris basin, with some differences on the age limits. Seven seismic units, bounded by time-lines, were mapped. Isopach map and wells correlations show four main results. (1) The Mid-Cimmerian (Toarcian-Aalenian) and Neo-Cimmerian (Berriasian) medium to long wavelength deformations are well recorded (with truncations) in this area. (2) Two main phases of extension, contemporaneous with the Tethys Alpine rift, of Early to Middle Liassic and Early Bajocian ages were characterized. The first one was mapped at the scale of France. (3) A medium to long wavelength flexural subsidence regime, initiated during Bathonian, occurred during Callovian to Oxfordian times, contemporaneous with the progradation of a carbonate platform toward the SSW. (4) Some major basement faults were active during all the Jurassic whatever the type of subsidence.
Tertiary ground birds from Patagonia (Argentina) in the Tournouër collection of the Muséum National d’Histoire Naturelle, Paris
Authors: Buffetaut Eric 
Published: May 2014

AbstractAvian fossils collected by André Tournouër in Patagonia during the early years of the 20th century are described. A small phorusrhacid (Psilopterus cf. affinis) is reported from the Deseadan (Late Oligocene). The Santacrucian (Early Miocene) remains belong to a rheid (Opisthodactylus patagonicus), phorusrhacids (Psilopterus sp., Phorusrhacos longissimus) and a brontornithid (Brontornis burmeisteri). Several characters of the lower jaw of Brontornis differ from those of phorusrhacids and support the inclusion of brontornithids in Anseriformes.
A Predictive Ordered Logistic Regression Model as a Tool for Quality Review of Control Risk Assessments
Authors: Issa Hussein , Kogan Alexander 
Published: May 2014

ABSTRACT
External auditors and management increasingly rely on control risk assessments conducted by internal auditors. Consequently, it is crucial to ensure the quality of such assessments and identify irregular instances that deviate from the normal pattern of assessments. Moreover, processing and prioritizing a large number of outlying internal auditors' assessments can help their superiors as well as external auditors overcome the human limitations of dealing with information overload and direct their investigations toward the more suspicious cases, consequently improving overall audit efficiency. In this paper, we use historic data consisting of control risk assessments procured from the internal audit department of a multinational consumer products company. It is used to infer an ordered logistic regression model to provide a quality review of internal auditors' and business owners' assessments of internal controls. We identify anomalous cases where the assessment does not conform to the expected value and develop a methodology to prioritize these outliers. The results indicate that the proposed model can serve as a quality review tool, thus improving audit efficiency, as well as a learning tool that non-experts can employ to gain expert-like knowledge. Additionally, the proposed ranking metrics proved effective in helping the auditors focus their efforts on the more problematic audits.
Enterprise Risk Management: Re-Conceptualizing the Role of Risk and Trust on Information Sharing in Transnational Alliances
Authors: Arnold Vicky , Benford Tanya S. , Hampton Clark , Sutton Steve G. 
Published: May 2014

ABSTRACT
Globalization places greater emphasis on the development of transnational alliances. The greatest benefits from alliances are derived from high-level information sharing, but vulnerability escalates with information sharing. This study examines risk in transnational alliances based on a theoretical model drawing from enterprise risk management (ERM) as a strategic management effort. This theoretical model posits that ERM strategies focus on business risk as the primary determinant of alliance partner selection and continuity, particularly within global relationships, whereas prior management control research focused on trust. The purpose of this study is to examine the influence of ERM on risk and trust associated with transnational alliances and the resulting impact on interorganizational information sharing. Survey data are gathered from 200 senior-level managers monitoring transnational alliances. Structural equation modeling is used to test the hypothesized relationships. Results provide strong support for the research model, showing that high ERM is associated with decreased risk, increased trust, and enhanced information sharing. Given the ongoing debate over the relationship directionality between trust and risk, we conducted additional sensitivity testing. Competing models focusing on trust as the key control mechanism are tested to assess the strength of our research model. Our risk-oriented research model demonstrates stronger explanatory power than competing models. Overall, our results show ERM substantially alters strategic management of transnational alliances, and has become a major influence on interorganizational risk, trust, and information sharing.

Published: May 2014

OBJECTIVE
Overnight hypoglycemia occurs frequently in individuals with type 1 diabetes and can result in loss of consciousness, seizure, or even death. We conducted an in-home randomized trial to determine whether nocturnal hypoglycemia could be safely reduced by temporarily suspending pump insulin delivery when hypoglycemia was predicted by an algorithm based on continuous glucose monitoring (CGM) glucose levels.

RESEARCH DESIGN AND METHODS
Following an initial run-in phase, a 42-night trial was conducted in 45 individuals aged 15–45 years with type 1 diabetes in which each night was assigned randomly to either having the predictive low-glucose suspend system active (intervention night) or inactive (control night). The primary outcome was the proportion of nights in which ≥1 CGM glucose values ≤60 mg/dL occurred.

RESULTS
Overnight hypoglycemia with at least one CGM value ≤60 mg/dL occurred on 196 of 942 (21%) intervention nights versus 322 of 970 (33%) control nights (odds ratio 0.52 [95% CI 0.43–0.64]; P &lt; 0.001). Median hypoglycemia area under the curve was reduced by 81%, and hypoglycemia lasting &gt;2 h was reduced by 74%. Overnight sensor glucose was &gt;180 mg/dL during 57% of control nights and 59% of intervention nights (P = 0.17), while morning blood glucose was &gt;180 mg/dL following 21% and 27% of nights, respectively (P &lt; 0.001), and &gt;250 mg/dL following 6% and 6%, respectively. Morning ketosis was present &lt;1% of the time in each arm.

CONCLUSIONS
Use of a nocturnal low-glucose suspend system can substantially reduce overnight hypoglycemia without an increase in morning ketosis.
Evaluation of Tensile Retention of Y-TZP Crowns After Long-term Aging: Effect of the Core Substrate and Crown Surface Conditioning

Published: May 2014

SUMMARY
This study evaluated the effect of the core substrate type (dentin and composite resin) on the retention of crowns made of yttrium oxide stabilized tetragonal zirconia polycrystal (Y-TZP), submitted to three inner surface conditionings. For this purpose, 72 freshly extracted molars were embedded in acrylic resin, perpendicular to the long axis, and prepared for full crowns: 36 specimens had crown preparations in dentin; the remaining 36 teeth had the crowns removed, and crown preparations were reconstructed with composite resin plus fiber posts with dimensions identical to the prepared dentin. The preparations were impressed using addition silicone, and 72 Y-TZP copings for the tensile test were produced. Cementation was performed with a dual-cured cement containing phosphate monomers. For cementation, the crown preparation (dentin or resin) was conditioned with the adhesive system, and the ceramic was subjected to one of three surface treatments: isopropyl alcohol, tribochemical silica coating, or thin low-fusing glassy porcelain layer application plus silanization. After 24 hours, all specimens were submitted to thermocycling (6000 cycles) and placed in a special tensile testing device in a universal testing machine to determine failure loads. The failure modes of all samples were analyzed under a stereomicroscope. Two-way analysis of variance showed that the surface treatment and substrate type (α=0.05) affected the tensile retention results. The dentin substrate presented the highest tensile retention values, regardless of the surface treatment. When the substrate was resin, the tribochemical silica coating and low-fusing glaze application plus silanization groups showed the higher retention values.
Novikov homology, jump loci and Massey products
Authors: Kohno Toshitake , Pajitnov Andrei 
Published: May 2014

AbstractLet X be a finite CW complex, and ρ: π 1(X) → GL(l, ℂ) a representation. Any cohomology class α ∈ H 1(X, ℂ) gives rise to a deformation γ t of ρ defined by γ t (g) = ρ(g) exp(t〈α, g〉). We show that the cohomology of X with local coefficients γ gen corresponding to the generic point of the curve γ is computable from a spectral sequence starting from H*(X, ρ). We compute the differentials of the spectral sequence in terms of the Massey products and show that the spectral sequence degenerates in case when X is a Kähler manifold and ρ is semi-simple.If α ∈ H 1(X, ℝ) one associates to the triple (X, ρ, α) the twisted Novikov homology (a module over the Novikov ring). We show that the twisted Novikov Betti numbers equal the Betti numbers of X with coefficients in the local system γ gen. We investigate the dependence of these numbers on α and prove that they are constant in the complement to a finite number of proper vector subspaces in H 1(X, ℝ).
