Truly the best of both worlds: Merging lineage-specific and universal probe kits to maximize phylogenomic inference.

Premise: Hybridization capture kits are now commonly used for reduced representation approaches in genomic sequencing, with both universal and clade-specific kits available. Here, we present a probe kit targeting 799 low-copy genes for the plant family Annonaceae.

Methods: This new version of the kit combines the original 469 genes from the previous Annonaceae kit with 334 genes from the universal Angiosperms353 kit.

Floral scent of eastern skunk cabbage (Symplocarpus foetidus: Araceae).

Symplocarpus foetidus (L.) Salisb. (eastern skunk cabbage) occurs across a broad geographic range of northeastern North America, blooming in winter between December and March.

Bipolar Electric Field Pulses in the Martian Magnetosheath and Solar Wind; Their Implication and Impact Accessed by System Scale Size.

The scale size of the plasma boundary region between the sheath and ionosphere in the Martian system is often similar to the gyro-radii of sheath protons, ∼200 km. As a result, ion energization via kinetic structures may play an important role in modifying the ion trajectories and thus be important when evaluating the large-scale dynamics of the Martian system. In this paper, we report observations made with the MAVEN Langmuir Probe and Waves instrument of solitary bipolar electric field structures, and assess their potential role in ion energization in the Martian system.

Electron Energy Partition across Interplanetary Shocks. I. Methodology and Data Product.

Analyses of 15,314 electron velocity distribution functions (VDFs) within ±2 hr of 52 interplanetary (IP) shocks observed by the spacecraft near 1 au are introduced. The electron VDFs are fit to the sum of three model functions for the cold dense core, hot tenuous halo, and field-aligned beam/strahl component. The best results were found by modeling the core as either a bi-kappa or a symmetric (or asymmetric) bi-self-similar VDF, while both the halo and beam/strahl components were best fit to bi-kappa VDF.

Pollination systems involving floral mimicry of fruit: aspects of their ecology and evolution.

Floral mimicry of nonfloral resources is found across many angiosperm families, with mimicry of varied models including carrion, dung, fungi, insects and fruit. These systems provide excellent models to investigate the role of visual and olfactory cues for the ecology and evolution of plant-animal interactions. Interestingly, floral mimicry of fruit is least documented in the literature, although ripe or rotting fruits play an important role as a food or brood site in many insect groups such as Diptera, Hymenoptera and Coleoptera, and frugivorous vertebrates such as bats and birds.

Unusual twig "twistiness" in pawpaw (Asimina triloba) provides biomechanical protection for distal foliage in high winds.

Premise Of Study: Deciduous woody species invest considerable resources in the growth of new foliage and distal stems. This new growth is at risk for mechanical damage from high winds and storms. Pawpaw has large leaves borne distally on thin twigs.

Development, validation, and results of a measure of 30-day readmission following hospitalization for pneumonia.

Background: Readmission following hospital discharge has become an important target of quality improvement.

Objective: To describe the development, validation, and results of a risk-standardized measure of hospital readmission rates among elderly patients with pneumonia employed in federal quality measurement and efficiency initiatives.

Design: A retrospective cohort study using hospital and outpatient Medicare claims from 2005 and 2006.

The olfactory component of floral display in Asimina and Deeringothamnus (Annonaceae).

Floral scent is a key component of floral display, and probably one of the first floral attractants linking insect pollinators to the radiation of Angiosperms. In this article, we investigate floral scent in two extra-tropical genera of Annonaceae. We discuss floral scent in the context of differing pollination strategies in these genera, and compare their scent to that of a close tropical relative.

Three case reports of laparoscopic management of granulosa cell tumor with intraoperative rupture and subsequent upstaging.

Granulosa cell tumors (GCT) of the ovary account for 2% to 5% of all ovarian tumors and typically demonstrate an indolent clinical course. For a young woman with stage IA disease who wishes to preserve fertility, conservative surgery with laparoscopic techniques can be a safe and effective method. Three patients with clinical presumptive stage IA GCT of the ovary were initially treated with conservative laparoscopic surgery with intraoperative rupture of the tumor.
