Feshbach-optimized photoassociation of ultracold 6^6Li87^{87}Rb molecules with short pulses

Two-color photoassociation of ground state $^6$Li$^{87}$Rb molecules via the $\mathrm{B}^1\Pi$ electronic state using short pulses near a magnetic Feshbach resonance is studied theoretically. A near-resonant magnetic field is applied to mix the hyperfine singlet and triplet components of the initial wave function and enhance the photoassociation rate, before the population is transferred to the ground state by a second pulse. We show that an increase of up to three orders of magnitude in the absolute number of molecules produced is attainable for deeply bound vibrational levels. This technique can be generalized to other molecules with accessible magnetic Feshbach resonances.Comment: 11 pages, 10 figures; submitted to Phys. Rev.

Discharge from Hospital to Home: Implementation and Use of the AHRQ IDEAL CHF Discharge Planning and AHA CHF Discharge Checklist

Section I: Abstract Problem: Hospital readmission rates in the congestive heart failure (CHF) population is a quality concern. As excessive readmissions tend to indicate low quality of care, government and private healthcare payers are increasing their focus on 30-day readmission rates as a new quality measure for hospitals. Context: This was a quality improvement project for a telemetry unit at a medical center in the Central Valley of California. There are 56,551 members in the Central Valley enrolled in the healthcare provider system and 2,567 patients with a primary or secondary diagnosis of CHF. Within the healthcare system, CHF was identified as the third most-admitted diagnosis to the telemetry unit, with an average stay of 5.4 days. Interventions: A multifaceted, evidence-based model was implemented using several interventions: (1) TeamSTEPPS Pre-Training Knowledge Assessment survey to gauge nurse CHF knowledge, (2) Agency for Healthcare Research and Quality IDEAL discharge planning resource, and (3) American Heart Association CHF discharge checklist. Measures: The goal of the project was to reduce the 30-day readmission rates for recently discharged patients from a baseline of 14% to 10% by July 2021, with a focus on the discharge education given to the patients and their family members. Results: Initially, there was a high level of interest and engagement among the nurses in educating the CHF patients and gauging their readiness for discharge. As the project progressed, nurse engagement faltered, with nursing staff reporting burn-out and increased stress from multiple improvement projects being implemented simultaneously. Patient feedback concluded that the discharge education provided by the nursing staff was beneficial and increased their comfort being discharged home to self-care. Due to time constraints with the project deadlines, the patient readmission rates could not be accurately assessed; although, results are expected to improve with the continuation of the education introduced during the project. Conclusion: Staff education on the available resources to assist them with CHF discharge education may increase the readiness of CHF patients to discharge home and reduce the 30-day readmission rates in the CHF patients on the telemetry unit in the Central Valley of California.

Introducing Just Competition Theory: Christian Realist Strategic Risk Management in Great Power Competition

How can a Christian Realist approach shape United States security policy to manage strategic risk during Great Power Competition? This work finds that Just War Theory, in particular jus in bello (behavior in war), is a common method used by Christian Realists to determine actions and manage consequences in war; however, it is not optimal for the challenges posed in Competition. A complementary structure uniquely applicable to actions below the threshold of armed conflict is needed. This argument is manifested through Just Competition Theory or jus in contentione. In a complex environment of Great Power Competition, principles of jus in contentione offer a better Christian Realist approach to strategic risk management than the principles of jus in bello. This claim is analytically supported using grounded theory methodology, incorporating a review of literature, content analysis of documents and structured interviews, comparative hypotheses testing, case studies, and a compatibility assessment. The principles of jus in contentione offer a complimentary Christian Realist method of analysis for the modern strategic context. Comparative hypotheses testing assesses them against historical military deployment data, a strategic risk assessment, a theoretical application of forces and activities, and the professional input of interview respondents. Two case studies using jus in contentione principles as explanatory factors provide further empirical support. An assessment of Classical Realism, Liberalism, and Constructivism shows this novel theory is most compatible with Christian Realism. Comprehensively, the research assesses that jus in contentione is a viable addendum to Just War Theory and a useful analytical tool for Great Power Competition policy and strategy

Controllable binding of polar molecules and meta-stability of 1-D gases with attractive dipole forces

We explore one-dimensional (1-D) samples of ultracold polar molecules with attractive dipole-dipole interactions and show the existence of a repulsive barrier due to a strong quadrupole interaction between molecules. This barrier can stabilize a gas of ultracold KRb molecules and even lead to long-range wells supporting bound states between molecules. The properties of these wells can be controlled by external electric fields, allowing the formation of long polymer-like chains of KRb, and studies of quantum phase transitions by varying the effective interaction between molecules. We discuss the generalization of those results to other systems
