Smoking cessation is the only effective intervention to slow down the accelerated decline in lung function in smokers with chronic obstructive pulmonary disease. Nevertheless, physicians often do not routinely provide evidence-based smoking cessation treatment to their patients. To understand underlying reasons, we explored how physicians engage in smoking cessation treatment in their chronic obstructive pulmonary disease patients. In total, 21 focus group discussions were held with general practitioners and pulmonologists in seven different countries in Europe and Asia...

In the vanadium oxyfluoride compound (NH_{4})_{2}[C_{7}H_{14}N][V_{7}O_{6}F_{18}] (DQVOF), the V^{4+} (3d^{1}, S=1/2) ions realize a unique, highly frustrated breathing kagome lattice composed of alternately sized, corner-sharing equilateral triangles. Here we present an ^{17}O NMR study of DQVOF, which isolates the local susceptibility of the breathing kagome network. By a fit to series expansion, we extract the ratio of the interactions within the breathing kagome plane, J_{∇}/J_{Δ}=0.55(4), and the mean antiferromagnetic interaction J[over ¯]=60(7)  K...

Molecular solids with cooperative electronic properties based purely on π electrons from carbon atoms offer a fertile ground in the search for exotic states of matter, including unconventional superconductivity and quantum magnetism. The field was ignited by reports of high-temperature superconductivity in materials obtained by the reaction of alkali metals with polyaromatic hydrocarbons, such as phenanthrene and picene, but the composition and structure of any compound in this family remained unknown. Here we isolate the binary caesium salts of phenanthrene, Cs(C14H10) and Cs2(C14H10), to show that they are multiorbital strongly correlated Mott insulators...

Kagomé lattice types have been of intense interest as idealized examples of extended frustrated spin systems. Here we demonstrate how the use of neutron diffraction and inelastic neutron scattering coupled with spin wave theory calculations can be used to elucidate the complex magnetic interactions of extended spin networks. We show that the magnetic properties of the coordination polymer Mn3(1,2,4-(O2C)3C6H3)2, a highly distorted kagomé lattice, have been erroneously characterized as a canted antiferromagnet in previous works...

PROBLEM: Vitae reviews, interviews, presentations, and reference checks are typical components of searches used to screen and select new department chairs/heads, but these strategies may fail to identify leaders who can communicate effectively with faculty in common, tense situations. APPROACH: Between May 2015 and November 2016, the authors piloted simulation scenarios in four department chair searches at Penn State College of Medicine/Penn State Health to assess candidates' skill at handling common, challenging situations with faculty members...

Controlling the number of monomers in a supramolecular polymer has been a great challenge in programmable self-assembly of organic molecules. One approach has been to make use of frustrated growth of the supramolecular assembly by tuning the balance of attractive and repulsive intermolecular forces. We report here on the use of covalent bond formation among monomers, compensating for intermolecular electrostatic repulsion, as a mechanism to control the length of a supramolecular nanofiber formed by self-assembly of peptide amphiphiles...

Since its proposal by Anderson, resonating valence bonds (RVB) formed by a superposition of fluctuating singlet pairs have been a paradigmatic concept in understanding quantum spin liquids. Here, we show that excitations related to singlet breaking on nearest-neighbour bonds describe the high-energy part of the excitation spectrum in YbMgGaO4, the effective spin-1/2 frustrated antiferromagnet on the triangular lattice, as originally considered by Anderson. By a thorough single-crystal inelastic neutron scattering study, we demonstrate that nearest-neighbour RVB excitations account for the bulk of the spectral weight above 0...

AIM AND OBJECTIVES: To obtain a deeper understanding of qualified intensive care nurses' experiences of caring for obese patients in intensive care. BACKGROUND: Admission of obese patients with complex health care needs to intensive care units is increasing. Caring for obese critically ill patients can be challenging and demanding for the intensive care nurse because of the patients' weight, critical situation, and physical challenges. There is a gap in knowledge at present about qualified intensive care nurses' experiences of caring for obese patients in intensive care units...

This commentary discusses the increasingly observed managerilisation of healthcare. Managerilisation frequently results in a framework of rules, regulations and accompanying time-consuming forms and procedures to guide decision-making. Although likely developed with the best of intentions in mind, this framework may be of limited value and tends to leave healthcare professionals feeling frustrated and distrusted. In addition, overzealous bureaucracy and rigid adherence to protocols may be disadvantageous to patient care and outcomes...

The goal of this study was to identify a relevant and inclusive list of quality of life issues among long-term survivors of melanoma. Individuals diagnosed with stage I-III cutaneous melanoma and had survived 1-5 years, ages 18-65 years at diagnosis, were recruited. Five focus groups were conducted with 33 participants in total. Discussions centered on participants' experiences at diagnosis, as well as ongoing physical, emotional, and social concerns, and behavioral changes since diagnosis. The majority of participants reported shock, fear, and feeling overwhelmed at the time of diagnosis...

BACKGROUND: Food insecurity (FI) remains a major public health problem. With the rise in suburban poverty, a greater understanding of parents' experiences of FI in suburban settings is needed to effectively screen and address FI in suburban practices. METHODS: We conducted 23 semistructured interviews with parents of children <4 years of age who presented for well-child care in 6 suburban pediatric practices and screened positive for FI. In the interviews, we elicited parents' perceptions of screening for FI, how FI impacted the family, and recommendations for how practices could more effectively address FI...

Getting students to complete reading assignments is often a source of frustration for nurse educators. Monte Carlo Quizzes (MCQs) were adapted for online delivery in a hybrid nursing course to encourage timely completion and deep processing of readings. Students indicated that MCQs motivated them to complete the assigned readings and to read more carefully. However, there were no significant differences on scores for other course assignments between those who completed readings and those who did not.

Lisa Roy, Boyli Ghosh, Ankan Paul
We employ quantum chemical calculations to study the hydrogenation of carbon dioxide by amine-boranes, NMe3BH3 ((Me3)AB) and NH3BH3 (AB) weakly bonded to a bulkier Lewis acid, Al(C6F5)3 (LA). Additionally, computations has also been conducted to elucidate the mechanism of hydrogenation of carbon dioxide by (Me3)AB while captured between one Lewis Base (P(o-tol3), (LB)) and two Lewis acids, Al(C6F5)3. In agreement to the experiments, our computational study predicts that hydride transfer to conjugated HCO2(‒), generated in the reaction of (Me3)AB-LA with CO2, is not feasible...

#19
Douglas M Hall, Gregory M Grason
Chirality frustrates and shapes the assembly of flexible filaments in rope-like, twisted bundles and fibres by introducing gradients of both filament shape (i.e. curvature) and packing throughout the structure. Previous models of chiral filament bundle formation have shown that this frustration gives rise to several distinct morphological responses, including self-limiting bundle widths, anisotropic domain (tape-like) formation and topological defects in the lateral inter-filament order. In this paper, we employ a combination of continuum elasticity theory and discrete filament bundle simulations to explore how these distinct morphological responses compete in the broader phase diagram of chiral filament assembly...

Liliana de Campo, Toen Castle, Stephen T Hyde
Star-shaped molecules with three mutually immiscible arms self-assemble to form a variety of novel structures, with conformations that attempt to minimize interfacial area between the domains composed of the different arms. The geometric frustration caused by the joining of these arms at a common centre limits the size and shape of each domain, encouraging the creation of complex and interesting solutions. Some solutions are tricontinuous, and these solutions (and others) share aspects of bicontinuous structures with amphiphilic assemblies as similar molecular segregation factors are at work...
