Spatial Ecology of the Coachwhip, Masticophis flagellum (Squamata: Colubridae), in Eastern Texas

We radio-tracked nine Masticophis flagellum (Coachwhips) to determine home range, habitat use, and movements in eastern Texas from April to October 2000. Home ranges of Coachwhips contained more oak savanna macrohabitat than early-successional pine plantation or forested seep, based on the availability of these three macrohabitats in the study area. Likewise, within their individual home ranges, Coachwhips used oak savanna more than the other two macrohabitats, based on availability. An analysis of microhabitat use revealed that, relative to random sites within their home range, Coachwhips were found at sites with fewer pine trees and more herbaceous vegetation taller than 30 cm. Results of the two analyses, macrohabitat and microhabitat, were consistent: oak savannas contained relatively few pine trees but much herbaceous vegetation taller than 30 cm. Coachwhips made frequent long-distance moves, which resulted in large home ranges. Core activity areas, however, were small. These core activity areas were always within the oak savanna macrohabitat. Long movements, large home ranges, and small core activity areas likely were a result of the preferred oak savanna macrohabitat being patchily distributed in the landscape

Brain connectivity analysis: a short survey

This short survey the reviews recent literature on brain connectivity studies. It encompasses all forms of static and dynamic connectivity whether anatomical, functional, or effective. The last decade has seen an ever increasing number of studies devoted to deduce functional or effective connectivity, mostly from functional neuroimaging experiments. Resting state conditions have become a dominant experimental paradigm, and a number of resting state networks, among them the prominent default mode network, have been identified. Graphical models represent a convenient vehicle to formalize experimental findings and to closely and quantitatively characterize the various networks identified. Underlying these abstract concepts are anatomical networks, the so-called connectome, which can be investigated by functional imaging techniques as well. Future studies have to bridge the gap between anatomical neuronal connections and related functional or effective connectivities

6-(4-Meth­oxy­phen­yl)-7-phenyl-2,3-dihydro-1H-pyrrolizine-5-carbaldehyde

The 4-meth­oxy­phenyl residue in the title compound, C21H19NO2, is oriented at a dihedral angle of 54.6 (5)° with respect to the phenyl ring and at a dihedral angle of 52.5 (8)° with respect to the pyrrole ring of the pyrrolizine system. The phenyl ring is oriented at a dihedral angle of 36.2 (5)° with respect to the pyrrole ring. The meth­oxy group makes a C—C—O—C torsion angle of 3.8 (9)° with the attached benzene ring

6-(4-Chloro­phen­yl)-7-phenyl-2,3-dihydro-1H-pyrrolizine-5-carbaldehyde

The 4-chloro­phenyl residue in the title compound, C20H16ClNO, is oriented at a dihedral angle of 53.6 (3)° towards the phenyl ring and 42.0 (9)° towards the pyrrole ring of the pyrrolizine template. The phenyl ring is oriented at a dihedral angle of 45.4 (4)° towards the pyrrole ring

Patients’ Attitudes Toward Deprescribing and Their Experiences Communicating with Clinicians and Pharmacists

Purpose: Developing effective deprescribing interventions relies on understanding attitudes, beliefs, and communication challenges of those involved in the deprescribing decision-making process, including the patient, the primary care clinician, and the pharmacist. The objective of this study was to assess patients’ beliefs and attitudes and identify facilitators of and barriers to deprescribing. Methods: As part of a larger study, we recruited patients ⩾18years of age taking ⩾3 chronic medications. Participants were recruited from retail pharmacies associated with the University of Kentucky HealthCare system. They completed an electronic survey that included demographic information, questions about communication with their primary care clinician and pharmacists, and the revised Patients’ Attitudes Toward Deprescribing (rPATD) questionnaire. Results: Our analyses included 103 participants (n=65 identified as female and n=74 as White/Caucasian) with a mean age of 50.4years [standard deviation (SD)=15.5]. Participants reported taking an average of 8.4 daily medications (SD=6.1). Most participants reported effective communication with clinicians and pharmacists (66.9%) and expressed willingness to stop one of their medications if their clinician said it was possible (83.5%). Predictors of willingness to accept deprescribing were older age [odds ratio (OR)=2.99, 95% confidence interval (CI)=1.45–6.2], college/graduate degree (OR=55.25, 95% CI=5.74–531.4), perceiving medications as less appropriate (OR=8.99, 95% CI=1.1–73.62), and perceived effectiveness of communication with the clinician or pharmacist (OR=4.56, 95% CI=0.85–24.35). Conclusion: Adults taking ⩾3 chronic medications expressed high willingness to accept deprescribing of medications when their doctor said it was possible. Targeted strategies to facilitate communication within the patient–primary care clinician–pharmacist triad that consider patient characteristics such as age and education level may be necessary ingredients for developing successful deprescribing interventions

NuSTAR and Suzaku X-ray Spectroscopy of NGC 4151: Evidence for Reflection from the Inner Accretion Disk

We present X-ray timing and spectral analyses of simultaneous 150 ks Nuclear Spectroscopic Telescope Array (NuSTAR) and Suzaku X-ray observations of the Seyfert 1.5 galaxy NGC 4151. We disentangle the continuum emission, absorption, and reflection properties of the active galactic nucleus (AGN) by applying inner accretion disk reflection and absorption-dominated models. With a time-averaged spectral analysis, we find strong evidence for relativistic reflection from the inner accretion disk. We find that relativistic emission arises from a highly ionized inner accretion disk with a steep emissivity profile, which suggests an intense, compact illuminating source. We find a preliminary, near-maximal black hole spin a>0.9 accounting for statistical and systematic modeling errors. We find a relatively moderate reflection fraction with respect to predictions for the lamp post geometry, in which the illuminating corona is modeled as a point source. Through a time-resolved spectral analysis, we find that modest coronal and inner disk reflection flux variation drives the spectral variability during the observations. We discuss various physical scenarios for the inner disk reflection model, and we find that a compact corona is consistent with the observed features.Comment: 20 pages, 12 figures, accepted for publication in Ap
