How immigration is framed in the media can influence ethnic attitudes and support for anti-immigration policies. This work analysed the effects of media representations about immigration (as an invasion or an opportunity for the economic growth of the country) on the perceptions (i.e., perceived [im]morality, realistic and symbolic threat) and emotions of anger and fear of Spanish (Study 1) and Italian participants (Study 2), and their willingness to accept anti-immigration policies proposed by far-right parties such as Vox (in Spain) or La Lega (in Italy). Results showed direct effects of news frames on perceived immorality, threat and anger in Spain. News frames indirectly affected support for anti-immigration policies through perceived immorality and realistic threat (serially). In Italy, news frames only affected perceived immorality and anger among Italians with rightist orientation. The opportunity-frame (vs. invasion-frame) was indirectly associated with less support for anti-immigration policies, through perceived immorality, for those with a more conservative orientation. These findings suggest that news frames can indirectly influence the support for anti-immigration parties through psychosocial processes in an era of political populism.

LINC complexes are transmembrane protein assemblies that physically connect the nucleoskeleton and cytoskeleton through the nuclear envelope. Dysfunctions of LINC complexes are associated with pathologies such as cancer and muscular disorders. The mechanical roles of LINC complexes are poorly understood. To address this, we used genetically encoded FRET biosensors of molecular tension in a nesprin protein of the LINC complex of fibroblastic and epithelial cells in culture. We exposed cells to mechanical, genetic, and pharmacological perturbations, mimicking a range of physiological and pathological situations. We show that nesprin experiences tension generated by the cytoskeleton and acts as a mechanical sensor of cell packing. Moreover, nesprin discriminates between inductions of partial and complete epithelial–mesenchymal transitions. We identify the implicated mechanisms, which involve α-catenin capture at the nuclear envelope by nesprin upon its relaxation, thereby regulating β-catenin transcription. Our data thus implicate LINC complex proteins as mechanotransducers that fine-tune β-catenin signaling in a manner dependent on the epithelial–mesenchymal transition program.
CDC42EP5/BORG3 modulates SEPT9 to promote actomyosin function, migration, and invasion

Published: August 2020

Fast amoeboid migration is critical for developmental processes and can be hijacked by cancer cells to enhance metastatic dissemination. This migratory behavior is tightly controlled by high levels of actomyosin contractility, but how it is coupled to other cytoskeletal components is poorly understood. Septins are increasingly recognized as novel cytoskeletal components, but details on their regulation and contribution to migration are lacking. Here, we show that the septin regulator Cdc42EP5 is consistently required for amoeboid melanoma cells to invade and migrate into collagen-rich matrices and locally invade and disseminate in vivo. Cdc42EP5 associates with actin structures, leading to increased actomyosin contractility and amoeboid migration. Cdc42EP5 affects these functions through SEPT9-dependent F-actin cross-linking, which enables the generation of F-actin bundles required for the sustained stabilization of highly contractile actomyosin structures. This study provides evidence that Cdc42EP5 is a regulator of cancer cell motility that coordinates actin and septin networks and describes a unique role for SEPT9 in melanoma invasion and metastasis.
Normal coordinates in a system of coupled oscillators and influence of the masses of the springs
Authors: Suárez Álvaro , Baccino Daniel , Monteiro Martín , Martí Arturo C
Published: August 2020

Experimental analysis of the motion in a system of two coupled oscillators with arbitrary initial conditions was performed and the normal coordinates were obtained directly. The system consisted of two gliders moving on an air track, joined together by a spring and joined by two other springs to the fixed ends. From the positions of the center of mass and the relative distance, acquired by analysis of the digital video of the experiment, normal coordinates were obtained, and by a non linear fit the normal frequencies were also obtained. It is shown that although the masses of the springs are relatively small compared to that of the gliders, it is necessary to take them into consideration to improve the agreement with the experimental results. This experimental-theoretical proposal is targeted to an undergraduate laboratory.
Wavefield reconstruction inversion: an example
Authors: Symes William W
Published: August 2020

Nonlinear least squares data-fitting driven by physical process simulation is a classic and widely successful technique for the solution of inverse problems in science and engineering. Known as ‘full waveform inversion (FWI)’ in application to seismology, it can extract detailed maps of earth structure from near-surface seismic observations, but also suffers from a defect not always encountered in other applications: the least squares error function at the heart of this method tends to develop a high degree of nonconvexity, so that local optimization methods (the only numerical methods feasible for field-scale problems) may fail to produce geophysically useful final estimates of earth structure, unless provided with initial estimates of a quality not always available. A number of alternative optimization principles have been advanced that promise some degree of release from the multimodality of FWI, amongst them wavefield reconstruction inversion (WRI), the focus of this paper. Applied to a simple 1D acoustic transmission problem, both full waveform and WRI methods reduce to minimization of explicitly computable functions, in an asymptotic sense. The analysis presented here shows explicitly how multiple local minima arise in FWI, and that WRI can be vulnerable to the same ‘cycle-skipping’ failure mode.

Published: August 2020

A flexible framework is obtained for enhancing both the thermal and electrical performance of fin field-effect transistor (FinFET) technology. Investigation of the nanoscale heat conduction within a short-channel field-effect transistor can be regarded as an emerging challenge related to future-generation transistors. In this work, we report the electrothermal transport in a 10 nm silicon-on-insulator (SOI) FinFET based on the dual-phase-lag model and modified drift-diffusion motions. We found that electron mobility decreases along the channel due to carrier confinement under higher electric field. In addition, the surface detection temperature indicates that the self-heating process is localized between the source and drain region. As promising results, high-κ metal-oxide and lower thermal boundary resistance can optimize the nanoscale heat transport in the SOI FinFET device.
A new IMU error parameter estimation method for hypersonic vehicle based on hybrid neural network
Authors: Guo Weilin , Xian Yong , Chang Xinlong , Ren Leliang , Lei Gang
Published: August 2020

To realize the effective estimation of the inertial measurement unit (IMU) error parameters of a hypersonic vehicle and satisfy the high-precision navigation requirements, a hybrid neural network (HYNN) method that consists of a quasi-Newton semi-determined weight neural network (QNSWNN) and a semi-determined weight recurrent neural network (SWRNN) is proposed. In contrast to conventional neural networks, the weights of the HYNN model, which are determined by the IMU error parameters, have physical meanings. First, the IMU error model and strap-down inertial navigation system (SINS) navigation model are established. Second, the QNSWNN model is constructed based on the SINS/celestial navigation system (CNS) integrated navigation system information. The quasi-Newton is used to adjust the weights, which include the gyroscope error. The rest weights of QNSWNN are fixed based on a SINS attitude calculation model. The gyroscope error parameters can be estimated during the QNSWNN training process. Lastly, the SWRNN model is constructed based on the SINS/GPS integrated navigation system information. The BP algorithm is used to adjust the weights, which include the accelerometer error. The rest weights of SWRNN are fixed based on the SINS navigation calculation model. The accelerometer error parameters can be estimated during the SWRNN training process. The simulation results show that the IMU error parameter can be effectively estimated by the HYNN, and the relative errors are below 25%. Moreover, when the signal of the auxiliary navigation system is interrupted, the HYNN method still has high prediction accuracy for the SINS navigation parameters.
Dielectric-loading approach for extra electric field enhancement and spatially transferring plasmonic hot-spots
Authors: Wan Mingjie , Wu Jingyu , Liu Jun , Chen Zhuo , Gu Ping , Zhan Peng , Wang Zhenlin , Bozhevolnyi Sergey I
Published: August 2020

Plasmonic nanoantennas have been widely explored for boosting up light-matter interactions due to their ability of providing strongly confined and highly enhanced electric near fields, so called ‘hot-spots’. Here, we propose a dielectric-loading approach for hot-spots engineering by coating the conventional plasmonic nanoantennas with a conformal high refractive index dielectric film and forming dielectric-loaded plasmonic nanoantennas. Compared to the conventional plasmonic nanoantennas, the corresponding dielectric-loaded ones that resonate at the same frequency are able to provide an extra enhancement in the local electric fields and meanwhile spatially transfer the hot spots to the dielectric surfaces. These findings have important implications for the design of optical nanoantennas with general applications in surface enhanced linear and nonlinear spectroscopies. As a demonstration application, we show that the maximum achievable fluorescence intensity in the dielectric-loaded plasmonic nanoantennas could be significantly larger than that in the conventional plasmonic nanoantennas.
Plasmon-modulated photoluminescence enhancement in hybrid plasmonic nano-antennas
Authors: Rashed Alireza R , Habib Mohsin , Das Nekhel , Ozbay Ekmel , Caglayan Humeyra
Published: August 2020

In this work, we performed a systematic study on a hybrid plasmonic system to elucidate a new insight into the mechanisms governing the fluorescent enhancement process. Our lithographically defined plasmonic nanodisks with various diameters act as receiver and transmitter nano-antennas to outcouple efficiently the photoluminescence of the coupled dye molecules. We show that the enhancement of the spontaneous emission rate arises from the superposition of three principal phenomena: (i) metal enhanced fluorescence, (ii) metal enhanced excitation and (iii) plasmon-modulated photoluminescence of the photoexcited nanostructures. Overall, the observed enhanced emission is attributed to the bi-directional near-field coupling of the fluorescent dye molecules to the localized plasmonic field of nano-antennas. We identify the role of exciton–plasmon coupling in the recombination rate of the sp-band electrons with d-band holes, resulting in the generation of particle plasmons. According to our comprehensive experimental analyses, the mismatch between the enhanced emission and the emission spectrum of the uncoupled dye molecules is attributed to the plasmon-modulated photoluminescence of the photoexcited hybrid plasmonic system.
Equivalence between non-Markovian dynamics and correlation backflows
Authors: De Santis Dario , Johansson Markus
Published: August 2020

The information encoded into an open quantum system that evolves under a Markovian dynamics is always monotonically non-increasing. Nonetheless, for a given quantifier of the information contained in the system, it is in general not clear if for all non-Markovian dynamics it is possible to observe a non-monotonic evolution of this quantity, namely a backflow. We address this problem by considering correlations of finite-dimensional bipartite systems. For this purpose, we consider a class of correlation measures and prove that if the dynamics is non-Markovian there exists at least one element from this class that provides a correlation backflow. Moreover, we provide a set of initial probe states that accomplish this witnessing task. This result provides the first one-to-one relation between non-Markovian quantum dynamics and correlation backflows. Finally, we introduce a measure of non-Markovianity.

Published: August 2020

Black phosphorous (BP), an excellent two-dimensional (2D) monoelemental layered p-type semiconductor material with high carrier mobility and thickness-dependent tunable direct bandgap structure, has been widely applied in various devices. As the essential building blocks for modern electronic and optoelectronic devices, high quality PN junctions based on semiconductors have attracted widespread attention. Herein, we report a junction field-effect transistor (JFET) by integrating narrow-gap p-type BP and ultra-wide gap n-type β-Ga2O3 nanoflakes for the first time. BP and β-Ga2O3 form a vertical van der Waals (vdW) heterostructure by mechanically exfoliated method. The BP/β-Ga2O3 vdW heterostructure exhibits remarkable PN diode rectifying characteristics with a high rectifying ratio about 107 and a low reverse current around pA. More interestingly, by using the BP as the gate and β-Ga2O3 as the channel, the BP/β-Ga2O3 JFET devices demonstrate excellent n-channel JFET characteristics with the on/off ratio as high as 107, gate leakage current around as low as pA, maximum transconductance (g
m) up to 25.3 µS and saturation drain current (I
DSS) of 16.5 µA/µm. Moreover, it has a pinch-off voltage of –20 V and a minimum subthreshold swing of 260 mV/dec. These excellent n-channel JFET characteristics will expand the application of BP in future nanoelectronic devices.

Published: August 2020

Two-dimensional material has been regarded as a competitive silicon-alternative with a gate length approaching sub-10 nm, due to its unique atomic thickness and outstanding electronic properties. Herein, we provide a comprehensively study on the electronic and ballistic transport properties of the puckered arsenene by the density functional theory coupled with nonequilibrium Green’s function formalism. The puckered arsenene exhibits an anisotropic characteristic, as effective mass for the electron/hole in the armchair and zigzag directions is 0.35/0.16 m
0 and 1.26/0.32 m
0. And it also holds a high electron mobility, as the highest value can reach 20 045 cm2V–1s–1. Moreover, the puckered arsenene FETs with a 10-nm channel length possess high on/off ratio above 105 and a steep subthreshold swing below 75 mV/dec, which have the potential to design high-performance electronic devices. Interestingly, the channel length limit for arsenene FETs can reach 7-nm. Furthermore, the benchmarking of the intrinsic arsenene FETs and the 32-bit arithmetic logic unit circuits also shows that the devices possess high switching speed and low energy dissipation, which can be comparable to the CMOS technologies and other CMOS alternatives. Therefore, the puckered arsenene is an attractive channel material in next-generation electronics.
Ca-Mg-Al-oxide Sorbents Prepared from Hydrotalcite Precursors for CO2 Capture at Realistic Calcium Looping Conditions
Authors: Kuo H T , Yu C T , Wei C H
Published: August 2020

The calcium looping (CaL) process, based on the cyclic carbonation/calcination of CaO sorbents, has been widely investigated recently as a potential technique to capture CO2 at reduced energy penalty. This process can be used in facilities such as power plants and produce a concentrated CO2 which is suitable for storage. In recent years, the hydrogen production processes become more important due to the development of sustainable energy. The CaL process can also be combined with reforming process to produce a concentrated stream of H2 >98 vol. % in a single step, which is known as sorption-enhanced reforming (SER) process, reducing the cost of H2 production effectively. The capture capacities and multicycle stabilities of sorbents are crucial in these uses. In this study, a series of CaMgAl oxide materials for CO2 capture, derived from layered-double hydroxides (LDHs), were prepared to test their performances at realistic calcium looping conditions, namely at high CO2 concentration in the calcination stage. A series of materials with different CaMgAl molar ratios were tested at different regeneration temperatures, regeneration times, and in different CO2 concentrations at the regeneration stage to find out the optimal treatment conditions. The multicycle capture capacities of these materials were examined and compared with that of limestone. Materials regenerated for 15 minutes at 930°C and 70∼100% CO2 had good performances. The Ca/Al = 7/1 materials possessed well capture capacity and multicycle stability compared with that of limestone. Addition of magnesium oxide can further improve its performance. In the 40 cycles test, although the initial capture capacity of the CaMgAl material was lower than that of the CaAl materials, because of the better stability of the former, its capture performance was better than that of the CaAl material at the end of the loop. These materials have the potential to be applied in hydrogen production and other related processes in the future.

Authors: Tanarat S , Hanjai P
Published: August 2020

Two-phase anaerobic treatment by a continuously stirred tank reactor (CSTR) and an upflow anaerobic sludge blanket (UASB) system was applied to treat slaughterhouse wastewater at ambient temperature, non-pH adjustment, at five different organic loading rates (OLR) of 1.39-2.60 kg COD/m3.d with the hydraulic retention time (HRT) in the range of 14.1-26.4 hr. The kinetic evaluation of the experimental data was carried out using a kinetic model derived from Michaelis-Menten and Monod equation. The maximum substrate utilization rate (kmax) and the half velocity constant (Ks) were 0.252 d−1 and 586.5 mg/l, respectively. The results indicated that the applied kinetic model is capable of explaining the bio-kinetic behaviour of the CSTR-UASB system and can be used as a design criteria for two-phase anaerobic treatment treating other fat-containing wastewater.

Mathieu groups are one type of the sporadic simple groups, they turn out not to be isomorphic to any member of the infinite families of finite simple groups. Study these groups is interesting since their orders are very high. Groupoid can be used to find the presentation of the subgroups of the Mathieu groups. The idea is creating a groupoid by acting the Mathieu group on a subset of this group and then calculating the presentation of the vertex group of the groupoid which represents the presentation of the subgroup as the vertex groups are isomorphic.

There are many engineering, physical and other applications that need special mathematical equations to solve them. One of the most important equations that have a large role in the applications of science is partial differential equations. The partial differential equations are two types: linear and nonlinear. There is a wide range of functional equations that highlight the importance of PDE for example: electrostatics, heat conduction, transmission line, quantum mechanics and wave theory. In this study we will discuss the theoretical part of those applications that are used PDEs, trying to clarify more than order of the partial differential equations in one, two, three dimensions.

Published: August 2020

Second harmonic generation (SHG) of two-dimensional (2D) layered materials has attracted immense research interests due to the abilities of photon generation, manipulation, transmission, detection, and imaging for the applications of modern on-chip nanophotonic devices. Some layered materials with broken inversion symmetry associated with their 2D nature enable the development of nanophotonic and nanooptoelectronic devices based on the second harmonic generation effect. Recently, many 2D materials with broken inversion symmetry have been discovered, which not only exhibit SHG quantum effects but also greatly promote the development of nanophotonics. In this review, we review the recent developments of all 2D SHG materials, including the graphene-like family, transition metal dichalcogenides, IIIA-VIA compounds and others.

Magnesium alloys are potential biodegradable hard-tissue implant materials because of their excellent biomechanical compatibility, biosafety, and absorbability. In order to further improve the biocompatibility of these alloys, a ceramic coating was prepared on the surface of a magnesium alloy specimen by plasma electrolytic oxidation (PEO) in a phosphate solution. The ceramic coating has a rough surface, porous structure, and no harmful elements in the ceramic membrane. Further, experiments with MG63 cells show that the PEO ceramic coating can promote cell adhesion and proliferation, and it causes no obvious cytotoxicity. In conclusion, PEO can be used to prepare a suitable ceramic coating on the surface of the magnesium alloy, thereby increasing its potential for clinical applications.
Computational feasibility of simulating whole-organ vascular networks

The human body contains approximately 20 billion blood vessels, which transport nutrients, oxygen, immune cells, and signals throughout the body. The brain's vasculature includes up to 9 billion of these vessels to support cognition, motor processes, and myriad other vital functions. To model blood flowing through a vasculature, a geometric description of the vessels is required. Previously reported attempts to model vascular geometries have produced highly-detailed models. These models, however, are limited to a small fraction of the human brain, and little was known about the feasibility of computationally modeling whole-organ-sized networks. We implemented a fractal-based algorithm to construct a vasculature the size of the human brain and evaluated the algorithm's speed and memory requirements. Using high-performance computing systems, the algorithm constructed a vasculature comprising 17 billion vessels in 1960 core-hours, or 49 minutes of wall-clock time, and required less than 32 GB of memory per node. We demonstrated strong scalability that was limited mainly by input/output operations. The results of this study demonstrated, for the first time, that it is feasible to computationally model the vasculature of the whole human brain. These findings provide key insights into the computational aspects of modeling whole-organ vasculature.
Implications of non-Markovian dynamics on information-driven engine

Published: August 2020

The understanding of memory effects arising from the interaction between system and environment is a key for engineering quantum thermodynamic devices beyond the standard Markovian limit. We study the performance of measurement-based thermal machine whose working medium dynamics is subject to backflow of information from the reservoir via collision based model. In this study, the non-Markovian effect is introduced by allowing for additional unitary interactions between the environments. We present two strategies of realizing non-Markovian dynamics and study their influence on the performance of the engine. Moreover, the role of system-environment memory effects on the engine work extraction and information gain through measurement can be beneficial in short time.
Probing the spectral dimension of quantum network geometries

Published: August 2020

We consider an environment for an open quantum system described by a ‘quantum network geometry with flavor’ (QNGF) in which the nodes are coupled quantum oscillators. The geometrical nature of QNGF is reflected in the spectral properties of the Laplacian matrix of the network which display a finite spectral dimension, determining also the frequencies of the normal modes of QNGFs. We show that an a priori unknown spectral dimension can be indirectly estimated by coupling an auxiliary open quantum system to the network and probing the normal mode frequencies in the low frequency regime. We find that the network parameters do not affect the estimate; in this sense it is a property of the network geometry, rather than the values of, e.g., oscillator bare frequencies or the constant coupling strength. Numerical evidence suggests that the estimate is also robust both to small changes in the high frequency cutoff and noisy or missing normal mode frequencies. We propose to couple the auxiliary system to a subset of network nodes with random coupling strengths to reveal and resolve a sufficiently large subset of normal mode frequencies.
Density matrix to quantum master equation (QME) model for arrays of Coulomb coupled quantum dots in the sequential tunneling regime
Authors: Singha Aniket
Published: August 2020

Coulomb coupled quantum dot arrays with staircase ground state configuration have been proposed in literature for enhancing heat-harvesting and refrigeration performance (Erdman et al 2018 Phys. Rev. B 98, 045433; Walldorf et al 2017 Phys. Rev. B 96, 115415; Daré 2019 Phys. Rev. B 100 195427; Zhang and Chen 2019 Physica E 114, 113635; Daré and Lombardo 2017 Phys. Rev. B 96, 115414; Zhang et al 2016 Energy
95, 593; Sánchez and Büttiker 2011 Phys. Rev. B 83 085428; Singha 2018 Phys. Lett. A 382, 3026). Due to their mutual Coulomb interaction, a performance analysis of such systems remains complicated and necessitates consideration of microscopic physics using density matrix formulation. However the path of transport analysis starting from the system Hamiltonian to density matrix formulation is complicated and lacks the simplicity and intuitive aspect of sequential electron transport conveyed by the quantum master equation (QME) approach. In this paper, starting from the system Hamiltonian and employing the density matrix formulation, I derive the QME of a system of three quantum dots, two of which are electro-statically coupled. The framework elaborated in this paper can be further extended to derive QME of systems with higher number of Coulomb coupled quantum dots. Hence, the formulation developed in this paper can pave the way towards an intuitive analysis of transport physics for an array of Coulomb coupled quantum dots in the sequential tunneling regime.
Multidisciplinary practice advancement: Role of a clinical pharmacy specialist in a pediatric specialty clinic
Authors: Lynton Jessica J , Mersch Alex , Ferguson Polly J
Published: August 2020

Purpose

To describe clinical pharmacy specialists’ role in improving the use of specialty medications within a pediatric outpatient setting.

The outpatient pediatric specialty clinic (PSC) at the University of Iowa added a clinical pharmacy specialist to multidisciplinary teams within the PSC to focus on patient education, providing clinical recommendations, coordinating insurance approval, addressing barriers to adherence, and performing follow-up monitoring. Supplemental activities include coordinating between the electronic health record–integrated on-site specialty pharmacy and the PSC, assisting with quality improvement projects, developing policy revisions, negotiating access to specialty products, and answering medication information questions. Benefits in workflow efficiency, documentation, and revenue generation resulting from implementation of the pharmacist within the PSC have been identified by the clinic and the specialty pharmacy. The specialty pharmacy identified an increase in the rate of specialty prescription capture from 14% to 50%, leading to an increase in revenue for the health system. Within 12 months of the addition of the pharmacist to the team, an improvement in the rate of 13-valent pneumococcal conjugate vaccine administration to pediatric patients of 25.7 percentage points, medication adherence of >90%, and a 75% relative increase in appropriate hydroxychloroquine dosing were recognized. Due to the pharmacist’s impact on the PSC, a full-time pharmacist was added to the pediatric team to cover additional clinics, and 2 benefits investigation technicians were hired and funded by the PSC.

Conclusion

An interdisciplinary team with an integrated pharmacist has facilitated sustainable improvements in medication access and adherence and clinical and quality measures, benefiting patients, the pediatric clinic, the specialty pharmacy, and the hospital organization.
The pharmacist’s role in implementation of the ABCDEF bundle into clinical practice
Authors: Schmidt Lauren E , Patel Sneha , Stollings Joanna L
Published: August 2020

Purpose

To summarize published data regarding implementation of the ABCDEF bundle, a multicomponent process for avoidance of oversedation and prolonged ventilation in intensive care unit (ICU) patients; discuss pertinent literature to support each bundle element; and discuss the role of the pharmacist in coordinating bundle elements and implementation of the ABCDEF bundle into clinical practice.

Neuromuscular weakness and ICU-acquired weakness are common among critically ill patients and associated with significant cost and societal burdens. Recent literature supporting early liberation from mechanical ventilation and early mobilization has demonstrated improved short- and long-term outcomes. With expanded use of pharmacy services in the ICU setting, pharmacists are well positioned to advocate for best care practices in ICUs. A dedicated, interprofessional team is necessary for the implementation of the ABCDEF bundle in inpatient clinical practice settings. As evidenced by a number of studies, successful implementation of the ABCDEF bundle derives from involvement by motivated and highly trained individuals, timely completion of individual patient care tasks, and effective leadership to ensure proper implementation and ongoing support. Factors commonly identified by clinicians as barriers to bundle implementation in clinical practice include patient instability and safety concerns, lack of knowledge, staff concerns, unclear protocol criteria, and lack of interprofessional team care coordination. This narrative review discusses research on bundle elements and recommendations for application by pharmacists in clinical practice.

Conclusions

Despite the benefits associated with implementation of the ABCDEF bundle, evidence suggests that the recommended interventions may not be routinely used within the ICU. The pharmacist provides the expertise and knowledge for adoption of the bundle into everyday clinical practice.
