Abstract
We present a detailed study of a molecular outflow feature in the nearby starburst galaxy NGC 253 using ALMA. We find that this feature is clearly associated with the edge of NGC 253's prominent ionized outflow, has a projected length of ∼300 pc, with a width of ∼50 pc, and a velocity dispersion of ∼40 km s−1, which is consistent with an ejection from the disk about 1 Myr ago. The kinematics of the molecular gas in this feature can be interpreted (albeit not uniquely) as accelerating at a rate of 1 km s−1 pc−1. In this scenario, the gas is approaching an escape velocity at the last measured point. Strikingly, bright tracers of dense molecular gas (HCN, CN, HCO+, CS) are also detected in the molecular outflow: we measure an HCN(1–0)/CO(1–0) line ratio of

in the outflow, similar to that in the central starburst region of NGC 253 and other starburst galaxies. By contrast, the HCN/CO line ratio in the NGC 253 disk is significantly lower (

), similar to other nearby galaxy disks. This strongly suggests that the streamer gas originates from the starburst, and that its physical state does not change significantly over timescales of ∼1 Myr during its entrainment in the outflow. Simple calculations indicate that radiation pressure is not the main mechanism for driving the outflow. The presence of such dense material in molecular outflows needs to be accounted for in simulations of galactic outflows.
Impact of a Locally Measured H0 on the Interpretation of Cosmic-chronometer Data
Authors: Wei Jun-Jie , Melia Fulvio , Wu Xue-Feng 
Published: February 2017

Abstract
Many measurements in cosmology depend on the use of integrated distances or time, but galaxies evolving passively on a timescale much longer than their age difference allow us to determine the expansion rate H(z) solely as a function of the redshift–time derivative dz/dt. These model-independent “cosmic chronometers” can therefore be powerful discriminators for testing different cosmologies. In previous applications, the available sources strongly disfavored models (such as ΛCDM) predicting a variable acceleration, preferring instead a steady expansion rate over the redshift range 0 ≲ z ≲ 2. A more recent catalog of 30 objects appears to suggest non-steady expansion. In this paper, we show that such a result is entirely due to the inclusion of a high, locally inferred value of the Hubble constant H
0 as an additional datum in a set of otherwise pure cosmic-chronometer measurements. This H
0, however, is not the same as the background Hubble constant if the local expansion rate is influenced by a Hubble Bubble. Used on their own, the cosmic chronometers completely reverse this conclusion, favoring instead a constant expansion rate out to z ∼ 2.
The BRAVE Program. I. Improved Bulge Stellar Velocity Dispersion Estimates for a Sample of Active Galaxies
Authors: Batiste Merida , Bentz Misty C. , Manne-Nicholas Emily R. , Onken Christopher A. , Bershady Matthew A. 
Published: February 2017

Abstract
We present new bulge stellar velocity dispersion measurements for 10 active galaxies with secure M
BH determinations from reverberation mapping. These new velocity dispersion measurements are based on spatially resolved kinematics from integral-field (IFU) spectroscopy. In all but one case, the field of view of the IFU extends beyond the effective radius of the galaxy, and in the case of Mrk 79 it extends to almost one half the effective radius. This combination of spatial resolution and field of view allows for secure determinations of stellar velocity dispersion within the effective radius for all 10 target galaxies. Spatially resolved maps of the first (V) and second (σ
⋆) moments of the line of sight velocity distribution indicate the presence of kinematic substructure in most cases. In future projects we plan to explore methods of correcting for the effects of kinematic substructure in the derived bulge stellar velocity dispersion measurements.

Published: February 2017

Abstract
We present optical spectrophotometric and near-infrared (NIR) photometric observations of the nova V2676 Oph covering the period from 2012 March 29 through 2015 May 8. The optical spectra and photometry of the nova have been taken from SMARTS and Asiago; the NIR photometry was obtained from SMARTS and Mt. Abu. The spectra were dominated by strong H i lines from the Balmer series, Fe ii, N i, and [O i] lines in the initial days, typical of an Fe ii type nova. The measured FWHM for the Hβ and Hα lines was 800–1200 km s−1. There was pronounced dust formation starting 90 days after the outburst. The J − K color was the largest among recent dust-forming novae.

Resumo: Objetivo: Investigar os principais fatores de risco para o desenvolvimento da retinopatia da prematuridade (ROP) nos prematuros da Unidade de Terapia Intensiva (UTI) Neonatal da Santa Casa de Misericórdia de Ponta Grossa. Métodos: Estudo retrospectivo, tipo caso controle, através da revisão de prontuários entre Janeiro/2010 à Dezembro/2014. Foram incluídas crianças com peso ao nascer ?1.500 gramas, idade gestacional ?37 semanas e, excluídos portadores de malformação congênita, não submetidos à fundoscopia e os com prontuários incompletos. Os fatores de risco foram comparados com análises uni e multivarida. Para as variáveis quantitativas foi empregado o Teste t, para as qualitativas o Teste Exato de Fisher e, após análise univariada utilizou-se regressão logística. Resultados: Foram selecionados 172 neonatos, divididos em grupos: controle com 154 (89,5%) e caso com 18 (10,5%). Os fatores estudados foram: idade gestacional, peso ao nascer, APGAR 1º e 5º minuto, uso de surfactante, tempo de oxigenoterapia, fração inspirada de oxigênio (FiO2) utilizada, icterícia, necessidade de fototerapia, desenvolvimento de broncodisplasia pulmonar, enterocolite necrotizante, hemorragia intracraniana e cirurgias. Perante a análise univariada a idade gestacional, peso ao nascer, APGAR 1º e 5º minuto, tempo de oxigenoterapia, FiO2 máxima, necessidade de surfactante, tempo de início da icterícia e nível de bilirrubina indireta apresentaram significância estatística (p<0,001). Após correção com análise multivariada não se obteve p significativo. Conclusão: A frequência da ROP encontrada foi inferior à da literatura, o estadiamento III predominou, 38,9% dos prematuros com ROP grave beneficiaram-se da fotocoagulação, confirmando que identificação, triagem e tratamento precoce dos prematuros são essenciais na prevenção da cegueira.
Tunable pinning effects produced by non‐uniform antidot arrays in YBCO thin films

Published: February 2017

Uniform, graded and spaced arrays of 3 μm triangular antidots in pulsed laser deposited YBa2Cu3O7 (YBCO) superconducting thin films are compared by examining the improvements in the critical current density they produced. The comparison is made to establish the role of their lithographically defined (non‐)uniformity and the effectiveness to control and/or enhance the critical current density. It is found that almost all types of non‐uniform arrays, including graded ones enhance over the broad applied magnetic field and temperature range due to the modified critical state. Whereas uniform arrays of antidots either reduce or produce no effect on compared to the original (as‐deposited) thin films.

Authors: Tien Yu‐En , Li Chan‐Jung , Liou Jing‐Ping , Chang Jang‐Yang , Huang Jin‐Ding 
Published: February 2017

AbstractMPT0B292 was identified through screening of compounds able selectively to acetylate α‐tubulins in cells and it exhibited potent anti‐tumor, anti‐angiogenesis and anti‐metastatic effects in vitro and in vivo. Because of its poor water solubility, MPT0B292 is difficult to formulate with conventional approaches and hence difficulties are experienced in research practices. MPT0B292 was mixed with albumin in an aqueous solvent to form drug albumin nanoparticles with a size range around 333 nm. Unbound fractions of these nanoparticles were investigated in different or the same albumin concentration solutions. Unlike most drugs, the binding of MPT0B292 in human serum albumin increased with increasing drug concentrations. An analytical method was also developed and validated to determine MPT0B292 in rat plasma. This analytical method was applied successfully to the intravenous pharmacokinetic study of MPT0B292 in rats. A single dose study was regularly done to characterize the pharmacokinetic properties of the drug. Additionally, a novel i.v. infusion study was carried out to verify the extraction ratio of MPT0B292. The pharmacokinetic analysis revealed that MPT0B292 was a high extraction ratio drug with high systemic clearance, a high volume of distribution and a short half‐life in rats.

ObjectivesThis study aimed to provide a systematic review of device‐associated thrombosis (DAT) after left atrial appendage occlusion (LAAO) with the Watchman, Amplatzer Cardiac Plug, and Amulet devices.BackgroundDAT is known as a complication of LAAO but data about its clinical impact is scarce.MethodsA systematic review of studies evaluating the incidence, treatment and clinical implications of DAT from January 2008 to September 2015 was conducted.ResultsA total of 30 studies describing DAT events were included in the analysis. The overall incidence of DAT was 3.9% (82 DAT for 2118 implanted devices). The median time from procedure to diagnosis of DAT was 1.5 months (IQR: 0–2.9). Most cases were diagnosed with transesophageal echocardiogram (TEE). The treatment consisted of low molecular weight heparin (LMWH) in 45.5% of cases, and oral anticoagulation (OAC) or other treatment modalities in 54.5%. Complete thrombus resolution was achieved in 95.0% of cases (100% with LMWH and 89.5% with OAC). Treatment duration varied greatly with a median treatment duration of 45 days (IQR: 14–135). Clinical events related to DAT consisted of neurologic events namely two transient ischemic attacks (2.4%) and four ischemic strokes (4.9%).ConclusionsDAT is an infrequent complication of percutaneous LAAO. It occurs mainly early after the procedure and is associated with a low rate of neurological complications. In the majority of cases, diagnosis is made during follow‐up imaging with TEE. Anticoagulation treatment seems to be safe and highly effective. Further studies are needed to evaluate the optimal management of DAT. © 2017 Wiley Periodicals, Inc.

ObjectiveOur objective was to evaluate sex‐differences in outcomes after trans‐catheter aortic valve replacement (TAVR) in a population‐based cohort from Ontario, Canada.BackgroundPrior studies comparing outcomes in men and women after TAVR have yielded divergent results. Some studies have suggested that women have better survival than men while others have not corroborated this finding.MethodsA retrospective observational cohort study was conducted using chart abstraction data on all TAVR procedures performed between 2007 and 2013 in Ontario, Canada. Patients who had emergency TAVR procedures were excluded. The primary outcome was all‐cause mortality at 30‐days and 1‐year. Secondary outcomes included mortality at last follow‐up, cause‐specific, and all‐cause hospital readmission. Inverse probability of treatment weighting (IPTW) using propensity score was used to adjust for baseline differences between men and women.ResultsThe final study cohort consisted of 453 women and 546 men with a mean follow‐up of 3.5 years. Women were generally older and more frail but had less comorbid conditions. Women had lower unadjusted mean EuroScores (7% ± 5% vs 8% ± 7%; P = 0.008), but underwent significantly more trans‐apical procedures (26.5% vs 19.2%; P = 0.006) than men. After IPTW, the groups were well balanced. Although mortality was numerically higher for women at 30‐days (7.2% vs 5.4%), this was not statistically significant (P = 0.34). At 1‐year, there was no difference in mortality (18.2% vs 19.2%; P = 0.85). There were no significant differences in all‐cause readmission.ConclusionIn this population‐based cohort including all patients undergoing TAVR, mortality or all‐cause readmission were not significantly different between men and women. © 2017 Wiley Periodicals, Inc.

BackgroundPatients presenting with acute coronary syndrome (ACS) are at increased risk of complications after percutaneous coronary intervention with stent placement compared to patients with stable angina (SA) treated in an elective setting. The novel pro‐healing COMBO stent is a bio‐engineered drug eluting stent designed to promote vessel healing. Therefore, the stent may reduce this difference in clinical outcomes between elective and ACS‐patients and prevent late stent thrombosis.Methods and ResultsThe European, prospective, multicenter, 1000 all‐comers patient REMEDEE registry evaluates clinical outcomes after COMBO stent placement in ACS‐ and elective patients. The primary endpoint at 12 months is target lesion failure (TLF), a composite of cardiac death, target‐vessel myocardial infarction and target lesion revascularization. A total of 49.9% (n = 498) of patients presented with acute coronary syndrome. TLF was 7.1% in ACS patients, definite and probable stent thrombosis was observed in 0.5% of ACS patients and in all within 9 days post stenting. We found no significant difference in TLF between ACS and non‐ACS patients and a low overall rate of TLF.ConclusionsThe COMBO stent is a safe and efficient device for patients presenting with ACS. Low ST rate and only early stent thrombosis were observed. © 2017 Wiley Periodicals, Inc.
Macrocyclic Oligothiophene with Stereogenic [2.2]Paracyclophane Scaffolds: Chiroptical Properties from π‐Transannular Interactions

Published: February 2017

AbstractThe enantiomers of a new cyclic oligothiophene, bridged by two pseudo‐ortho[2.2]paracyclophanes, were synthesized as a new class of the chiral π‐conjugated system. Single‐crystal X‐ray diffraction analysis revealed a twisted structure for these oligothiophenes induced by a torsion of the cyclophane moieties. The embedding oligothiophenes into the inherent planar chirality provided a significant enhancement in circular dichroism (CD) spectra thanks to the large magnetic/electric transition dipole moments. In the dicationic state, an intramolecular π dimer was formed due to the strong interactions of the oligothiophenes. We further recorded unprecedented wide ranges of CD spectra in 250–1800 nm region. The transitions are reasonably described by the exciton coupling of the oligothiophenes.

Background and ObjectiveNeuroendocrine liver metastasis tumors (NELM) are a heterogeneous group of neoplasms with varied histologic features and a wide range of clinical behaviors. We aimed to identify the fraction of patients cured after liver surgery for NELM.MethodsCure fraction models were used to analyze 376 patients who underwent hepatectomy with curative intent for NELM.ResultsThe median and 5‐year disease‐free survival (DFS) were 4.5 years and 46%, respectively. The probability of being cured from NELM by liver surgery was 44%; the time to cure was 5.1 years. In a multivariable cure model, type of neuroendocrine tumor (NET), grade of tumor differentiation, and rate of liver involvement resulted as independent predictors of cure. The cure fraction for patients with well differentiated NELM from gastrointestinal NET or a functional pancreatic NET, and with <50% of liver‐involvement was 95%. Patients who had moderately/poorly differentiated NELM from a non‐functional pancreatic NET, and with <50% of liver‐involvement was 43%. In the presence of all the three unfavorable prognostic factors (nonfunctional PNET, liver involvement >50%, moderately/poorly differentiation), the cure fraction was 8%.ConclusionsStatistical cure after surgery for NELM is possible, and allow for a more accurate prediction of long‐term outcome among patients with NELM undergoing liver resection.
When Banks Lobby: The Effects of Organizational Characteristics and Banking Regulations on International Bank Lobbying
Authors: Chalmers Adam William 
Published: February 2017

AbstractThis article examines bank lobbying in the Basel Committee on Banking Supervision (BCBS). While excessive bank lobbying is routinely linked to weakened banking regulations, we still know little about bank mobilization patterns. In particular, when and why do some banks lobby the BCBS while others do not? I argue that the decision to lobby is a function of two factors: banks’ organizational characteristics and domestic banking regulations. I test my argument using a unique dataset of over 33,000 banks worldwide during the period in which Basel III was negotiated. My findings confirm a pronounced bias in bank mobilization patterns toward wealthy, internationally active banks. I also find that banks facing more stringent banking regulations at home tend to lobby the BCBS in an effort to level the playing field with international competitors. This effect is particularly salient for stringent regulations on banking activities as well as higher capital adequacy requirements.1
Campanian and Maastrichtian plagioptychid rudists (Hippuritida, Bivalvia) of the Chiapas Central Depression, southern Mexico
Authors: Pons Jose Maria , Vicens Enric , García-Barrera Pedro 
Published: February 2017

AbstractPlagioptychids are a conspicuous, although minor, component in uppermost Cretaceous rudist-bearing outcrops of the Caribbean Province, where other rudist families are more abundant and diverse. In the Chiapas Central Depression, the plagioptychid rudist fauna includes the following taxa: Plagioptychus antillarum (Douvillé) and Mitrocaprina sp. from the middle Campanian Suchiapa Formation, Plagioptychus muellerriedi Alencáster from the early Maastrichtian Ocozocoautla Formation, and Plagioptychus fragilis Chubb and Mitrocaprina tschoppi (Palmer) from the late Maastrichtian Angostura Formation. These five species are described in detail and some probable synonymies are discussed. Analysis of the literature on American plagioptychids reveals that the characters of too many taxa are still insufficiently known to attempt any thorough phylogenetic analysis. Other lines of evidence also seem to indicate that American Plagioptychidae diversity is probably higher than recognized today, which might result in a more significant difference to Plagioptychidae of the Mediterranean Tethys.
Absolute equation of state measurement of aluminum using laser quasi-isentropic-driven flyer plate

Published: February 2017

AbstractIn this paper, we perform an absolute equation of state (EOS) measurement on the principal Hugoniot of aluminum using a near-symmetric impact method. The flyer plates are accelerated to high velocities using the laser-ramp-driven method. An aluminum flyer plate of ~25 µm is accelerated to the velocity range from 4 to 12 km/s. Then the aluminum flyer plate propagates across a vacuum gap and impacts with an aluminum step target. A line-imaging optical recording velocity interferometer for any reflector (ORVIS) is used to measure the aluminum flyer plate and the shock velocity simultaneously. Aluminum EOS data were measured with pressures range from 50 to 200 GPa. This absolute EOS measurement method may be used for studying a variety of materials.
