Deformation-Induced Crystal Growth or Redissolution, and Crystal-Induced Strengthening or Ductilization in Metallic Glasses Containing Nanocrystals.

It is generally known that the incorporation of crystals in the glass matrix can enhance the ductility of metallic glasses (MGs), at the expense of reduced strength, and that the deformation of MGs, particularly during shear banding, can induce crystal formation/growth. Here, we show that these known trends for the interplay between crystals and deformation of MGs may hold true or become depending on the size of the crystals relative to the shear bands. We performed molecular dynamics simulations of tensile tests on nanocrystal-bearing MGs.

Supporting Biomedical Research Training for Historically Underrepresented Undergraduates Using Interprofessional, Nonformal Education Structures.

Research experience provides critical training for new biomedical research scientists. Students from underrepresented populations studying science, technology, engineering, and mathematics (STEM) are increasingly recruited into research pathways to diversify STEM fields. However, support structures outside of research settings designed to help these students navigate biomedical research pathways are not always available; nor are program support components outside the context of laboratory technical skills training and formal mentorship well understood.

Xylem network connectivity and embolism spread in grapevine(Vitis vinifera L.).

Xylem networks are vulnerable to the formation and spread of gas embolisms that reduce water transport. Embolisms spread through interconduit pits, but the three-dimensional (3D) complexity and scale of xylem networks means that the functional implications of intervessel connections are not well understood. Here, xylem networks of grapevine (Vitis vinifera L.

A Randomized Trial of Multiple-Patient Simulation Preparation to Improve Novice Nurses' Competence and Self-Efficacy.

Aim: The purpose of the study was to determine best practices for multiple-patient simulation (MPS) preparation and frequency to improve behavioral performance in nursing students.

Background: MPS provides a safe environment for novice nurses to practice priority setting, delegation, and multitasking, but evidence for best practices is needed.

Method: A multisite, blinded, randomized trial was conducted to evaluate the effect of three simulation preparation methods (expert modeling, voice-over PowerPoint, and reading assignments) on students' competence and self-efficacy for providing care to multiple patients in the simulation lab.

COMPARISON OF NON-CONTACT AND CONTACT TIME-LOSS LOWER QUADRANT INJURY RATES IN MALE COLLEGIATE BASKETBALL PLAYERS: A PRELIMINARY REPORT.

Background: Male collegiate basketball (BB) players are at risk for musculoskeletal injury. The rate of time-loss injury in men's collegiate BB, for levels of National Collegiate Athletic Association (NCAA) competition, ranges from 2.8 to 4.

Low Self-Esteem Predicts Indirect Support Seeking and Its Relationship Consequences in Intimate Relationships.

Indirect support seeking involves sulking, whining, and/or displaying sadness to elicit social support. Ironically, this strategy tends to backfire by prompting rejection from close others. The current research examines how low self-esteem contributes to the use and relational consequences of indirect support seeking during couples' interactions.

Methods for characterizing the fate and effects of nano zerovalent iron during groundwater remediation.

The emplacement of nano zerovalent iron (nZVI) for groundwater remediation is usually monitored by common measurements such as pH, total iron content, and oxidation-reduction potential (ORP) by potentiometry. However, the interpretation of such measurements can be misleading because of the complex interactions between the target materials (e.g.
