description: The Professional Governance Model (PGM) is used in healthcare to provide a structure that empowers frontline professional nurses to work collaboratively with leadership to contribute to organizational changes. Participation in Professional Governance (PG) provides nurses a structure to establish deeper accountability and autonomy through professional leadership activities to improve the work environment and the quality of care provided to patients. A comprehensive evaluation of the PGM is needed to determine if it successfully produces professional governance, defined as autonomy, accountability, collegiality, and professional obligation. There is currently no comprehensive way to evaluate the outcomes of PG at the project facility. Given the substantial financial commitment of an organization to support PG, it is necessary to establish a clear process and metrics to evaluate and track the overall effectiveness of a PGM in improving practice outcomes. A literature review was conducted to identify evidence-based practice outcomes resulting from an effective PGM. An innovative toolkit was created using evidence-based measures to assess the effectiveness of the current PG model in producing positive nursing practice outcomes. The toolkit evaluated the strength of professional governance and assessed the effectiveness of PG facilitation strategies. The toolkit components included nurse engagement scores, patient experience scores, turnover rates, measurement of the outcomes achieved by the unit-based council, and associated cost savings. Higher engagement scores (p= < .001), increased culture of safety (p= < .001), and reduced turnover (p= 0.01) were all significantly correlated to higher PG scores. Evaluating performance for each of these outcomes provides a comprehensive overview of areas for improvement and implementation of best practices for PG. Reassessment of PG at regular intervals is recommended to determine if investments have successfully produced the intended professional accountability and empirical outcomes.

description: It is well known that in q-matroids, axioms for independent spaces, bases, and spanning spaces differ from the classical case of matroids, since the straightforward q-analogue of the classical axioms does not give a q-matroid. For this reason, a fourth axiom has been proposed. In this paper we show how we can describe these spaces with only three axioms, providing two alternative ways to do that. As an application, we show direct cryptomorphisms between independent spaces and circuits and between independent spaces and bases.

description: Purpose: To perform a program evaluation using retrospective data from the GetFIT for CRC program implemented at a group of primary care clinics in Southern California. This program aimed to improve annual FIT (fecal immunochemical testing) compliance for colorectal cancer (CRC) screening. Background: The U.S. Multi-Society Task Force on CRC suggests60% FIT completion rate as a key quality metric; however, at this group of primary care clinics the average FIT completion rate was 45.8% for adults aged 50-75. Methods: Using the Logic Model framework, this program evaluation focused on assessing changes produced by strategies utilized in the program through evaluation of CRC screening rates, effectiveness of reminders, and patient satisfaction with the new process. The program implemented enhanced provider recommendation for screening, patient given test in office, brief education highlighting the importance of screening, incorporated simplified language instructions for collection, instructions handed to patients by nursing staff, reduced steps to complete FIT, and initiated reminder calls/texts. Results: Compared to the 2019 average FIT completion rate of 45.8% (N=240), the completion rates increased to 65.4% (N=561) six months postimplementation, indicating the program was successful based on IHI rules for special cause variation on the control chart. Patient satisfaction scores averaged 8.75 to 8.97 on a Likert scale of one(lowest) to ten (highest), indicating high satisfaction with the process. Phone call (N=462) and text reminders (N=488) were not shown to improve screening completion rates. Implications: The GetFIT for CRC program was successful in increasing CRC screening compliance via FIT.

description: The Veterans Justice Outreach Program is a tool of the Department of Veterans Affairs connecting Justice-Involved Veterans (JIV) with services with the mission of reducing reincarcerations, homelessness, and other negative outcomes. At the project site, mental health nurse practitioners (NPs) provide treatment to JIV using standard practices, including psychiatric assessment, medication, and psychotherapy. Despite various researchers denoting the importance of using specialized care when treating high-risk groups, practices were not aligned with recommendations. To optimize outcomes among JIV and enhance confidence among nurse practitioners, evidence-based practice guidelines were implemented. Literature shows trauma-informed care, substance use disorder treatment (using pharmacotherapy), using the risk needs responsivity (RNR) model to guide treatment planning, and utilizing Moral Reconation Therapy and motivational interviewing as fundamental for treatment of this population. Providers should understand that JIV is at higher-than-average risk for HIV, hepatitis, suicide, and drug overdose. Training was provided detailing the elements associated with best outcomes for JIV. NPs were provided the training and a pre-/posttest assessment to evaluate understanding and confidence about roles, responsibilities, and best practices for JIV (n=12, n=10). Veterans were evaluated to compare how the implementation of NP education influenced housing status, employment status, and recidivism gained from the electronic health record. Using an independent t-test and Levene’s test for variance denoted a postintervention mean of t (18) = -3.903, p = 0.001. The findings demonstrate a significant improvement in NP confidence and understanding of training elements. Veteran outcomes were unchanged as the time to data collection was abbreviated.
Architecture-Aware Online Failure Prediction For Software Systems
Creators: name: Pitakrat, Teerat
Publisher: name: Zenodo
Year: 2017

description: Failures at runtime in complex software systems are inevitable because these systems usually contain a large number of components. Having all components working perfectly at the same time is, if at all possible, very difficult. Hardware components can fail and software components can still have hidden faults waiting to be triggered at runtime and cause the system to fail.

Existing online failure prediction approaches predict failures by observing the errors or the symptoms that indicate looming problems. This observable data is used to create models that can predict whether the system will transition into a failing state. However, these models usually represent the whole system as a monolith without considering their internal components.

This dissertation proposes an architecture-aware online failure prediction approach, called Hora. The Hora approach improves online failure prediction by combining the results of failure prediction with the architectural knowledge about the system. The task of failure prediction is split into predicting the failure of each individual component, in contrast to predicting the whole system failure. Suitable prediction techniques can be employed for different types of components. The architectural knowledge is used to deduct the dependencies between components which can reflect how a failure of one component can affect the others. The failure prediction and the component dependencies are combined into one model which employs Bayesian network theory to represent failure propagation. The combined model is continuously updated at runtime and makes predictions for individual components, as well as inferring their effects on other components and the whole system.

The evaluation of component failure prediction is performed on three different experiments. The predictors are applied to predict component failures in a microservice-based application, critical events in Blue Gene/L supercomputer, and computer hard drive failures. The results show that the failures of individual components can be accurately predicted. The evaluation of the whole Hora approach is carried out on a microservice-based application. The results show that the Hora approach, which combines component failure prediction and architectural knowledge, can predict the component failures, their effects on other parts of the system, and the failures of the whole service. The Hora approach outperforms the monolithic approach that does not consider architectural knowledge and can improve the area under the Receiver Operating Characteristic (ROC) curve by 9.9%.

Atmospheric monitoring and array calibration in CTA using the Cherenkov Transparency Coefficient

Publisher: name: Deutsches Elektronen-Synchrotron, DESY, Hamburg
Year: 2017

description: The Cherenkov Telescope Array (CTA) will be the next generation observatory employing different types of Cherenkov telescopes for the detection of particle showers initiated by very-high-energy gamma rays. A good knowledge of the Earths atmosphere, which acts as a calorimeter in the detection technique, will be crucial for calibration in CTA. Variations of the atmospheres transparency to Cherenkov light and not correctly performed calibration of individual telescopes in the array result in large systematic uncertainties on the energy scale. The Cherenkov Transparency Coefficient (CTC), developed within the H.E.S.S. experiment, quantifies the mean atmosphere transparency ascertained from data taken by Cherenkov telescopes during scientific observations. Provided that atmospheric conditions over the array are uniform, transparency values obtained per telescope can be also used for the calibration of individual telescope responses. The application of the CTC in CTA presents a challenge due to the greater complexity of the observatory and the variety of telescope cameras compared with currently operating experiments, such as H.E.S.S. We present here the first results of a feasibility study for extension of the CTC concept in CTA for purposes of the inter-calibration of the telescopes in the array and monitoring of the atmosphere.

description: The foreseen implementations of the Small Size Telescopes (SST) in CTA will provide unique insights into the highest energy gamma rays offering fundamental means to discover and under- stand the sources populating the Galaxy and our local neighborhood. Aiming at such a goal, the SST-1M is one of the three different implementations that are being prototyped and tested for CTA. SST-1M is a Davies-Cotton single mirror telescope equipped with a unique camera technology based on SiPMs with demonstrated advantages over classical photomultipliers in terms of duty-cycle. In this contribution, we describe the telescope components, the camera, and the trigger and readout system. The results of the commissioning of the camera using a dedicated test setup are then presented. The performances of the camera first prototype in terms of expected trigger rates and trigger efficiencies for different night-sky background conditions are presented, and the camera response is compared to end-to-end simulations.

description: One of the main goals of the Cherenkov Telescope Array (CTA) observatory is to improve the $\gamma$-ray detection sensitivity by an order of magnitude, compared to the current ground-based observatories. Widening the energy coverage down to 20 GeV and up to 300 TeV is also an important goal. This goal will be possible by using Large-Sized Telescopes (LSTs) for the energy range of 20--200 GeV, Medium-Sized Telescopes (MSTs) for 100 GeV--10 TeV, and Small-Sized Telescopes (SSTs) for energies above 5 TeV. The LSTs, which focus on the lowest energies, are operated in a region dominated by background events originated from the night sky background. To reduce such background events as much as possible, the LST cameras are only read out if at least two of them have been triggered in a short-time coincidence window. Such trigger is implemented for each LST camera in a dedicated module called Trigger Interface Board (TIB). In addition, the TIB is also used in MSTs equipped with the NectarCAM camera system to manage the different trigger and timing signals between LSTs and MSTs, as well as to monitor the different counting rates and dead-time of the cameras. It also assigns a time stamp to each event, which is recorded along with the information provided by the CTA global timing distribution system, based on the White Rabbit protocol. Therefore, the event arrival time can be determined in a redundant way. In this contribution, the main features and the technical performance of the TIB are presented.

description: The Cherenkov Telescope Array (CTA) is an international project for a next-generation ground-based gamma ray observatory, aiming to improve on the sensitivity of current-generation experiments by an order of magnitude and provide energy coverage from 30 GeV to more than 300 TeV. The 9.7m Schwarzschild-Couder (SC) candidate medium-size telescope for CTA exploits a novel aplanatic two-mirror optical design that provides a large field of view of 8 degrees and substantially improves the off-axis performance giving better angular resolution across all of the field of view with respect to single-mirror telescopes. The realization of the SC optical design implies the challenging production of large aspherical mirrors accompanied by a submillimeter-precision custom alignment system. In this contribution we report on the status of the implementation of the optical system on a prototype 9.7 m SC telescope located at the Fred Lawrence Whipple Observatory in southern Arizona.

description: The Gamma-ray Cherenkov Telescope (GCT) is one of the Small Size Telescopes (SSTs) proposed for the Cherenkov Telescope Array (CTA) aimed at the 1 TeV to 300 TeV energy range. GCT will be equipped with a Compact High-Energy Camera (CHEC) containing 2048 pixels of physical size about 6$\times$6~mm$^2$, leading to a field of view of over 8 degrees. Electronics based on custom TARGET ASICs and FPGAs sample incoming signals at a gigasample per second and provide a flexible triggering scheme. Waveforms for every pixel in every event are read out are on demand without loss at over 600 events per second. A GCT prototype in Meudon, Paris saw first Cherenkov light from air showers in late 2015, using the first CHEC prototype, CHEC-M. This contribution presents results from lab and field tests with CHEC-M and the progress made to a robust camera design for deployment within CTA.

description: The Cherenkov Telescope Array is the main global project of ground-based gamma-ray astronomy for the coming decades. Performance will be significantly improved relative to present instruments, allowing a new insight into the high-energy Universe [1]. The nominal CTA southern array will include a sub-array of seventy 4 m telescopes spread over a few square kilometers to study the sky at extremely high energies, with the opening of a new window in the multi-TeV energy range. The Gamma-ray Cherenkov Telescope (GCT) is one of the proposed telescope designs for that sub-array. The GCT prototype recorded its first Cherenkov light on sky in 2015. After an assessment phase in 2016, new observations have been performed successfully in 2017. The GCT collaboration plans to install its first telescopes and cameras on the CTA site in Chile in 2018-2019 and to contribute a number of telescopes to the subsequent CTA production phase.

description: Determination of the energy and flux of the gamma photons by Imaging Atmospheric Cherenkov Technique is strongly dependent on optical properties of the atmosphere. Therefore, atmospheric monitoring during the future observations of the Cherenkov Telescope Array (CTA) as well as anticipated long-term monitoring in order to characterize overal properties and annual variation of atmospheric conditions are very important. Several instruments are already installed at the CTA sites in order to monitor atmospheric conditions on long-term. One of them is a Sun/Moon photometer CE318-T, installed at the Southern CTA site. Since the photometer is installed at a place with very stable atmospheric conditions, it can be also used for characterization of its performance and testing of new methods of aerosol optical depth (AOD) retrieval, cloud-screening and calibration. In this work, we describe our calibration method for nocturnal measurements and the modification of cloud-screening for purposes of nocturnal AOD retrieval. We applied these methods on two months of observations and present the distribution of AODs in four photometric passbands together with their uncertainties.

description: First case late starts (FCLS) are a common cause of delays in surgical procedure units. Such delays can have an increased impact on healthcare facilities, staff, and patients. When delays are unidentified or mitigated, several factors are directly impacted, such as safe surgical practices, quality of care, patient experience, and overall unit functionality, including communication and coordination. Potential negative patient outcomes include increased length of stay, additional or repetitive surgical procedures, hospital readmissions, return medical visits, and increased follow-up patient care. Disruptions in first cases can cause a continual patient flow dysfunction for the rest of the surgical day. First case late starts have been identified in a large Veterans’ Affairs Medical Center in Southern California within the Interventional Radiology Surgical Unit (IRSU). Therefore, this Doctor of Nursing Practice project aims to identify causes and implement mitigation strategies to reduce delays in the IRSU. The purpose of this Doctor of Nursing Practice quality improvement project is to adapt, implement, and evaluate a patient intake form to identify and mitigate the causes of FCLS in the IRSU. Additionally, an iteration of the Radiological Patient Safety System checklist will be adapted to align with the project facility's IRSU causative factors for FCLS delays. Using quality improvement methods and following the Plan-Do-Study-Act framework, an evidence-based fact sheet for staff education was developed and disseminated, a flow map, intake form aimed at identifying specific causes of delays, and the development of a modified Radiological Patient Safety System with team input is currently underway. Data collection included descriptive data for FCLS using the new intake form across three months. Weekly team meetings review ongoing data collection and analysis and identifiable causes of delays. This QI is part of a three-year-long ongoing project and is up-to-date. Unknown causes of FCLS average are between 78%-100% of all delayed cases in the project unit. An in-service was held to educate staff using a developed evidence-based fact sheet of causes and outcomes of FCLS in the IRSU. Staff was also educated on the project process, including a new intake form and a modified surgical safety checklist draft. Data collection and analysis showed that by implementing the new intake form, non-documentation of causes of FCLS dropped from an average of 78% to 38%. Overall, the system goals were met through teamwork, communication, and hardwiring of an evidence-based standardized process in the IRSU. Project outcomes target increasing patient safety and improving the overall quality of care by identifying FCLS by using PDSA cycles. The project will continue after the delayed reasons are identified and addressed in the modified surgical safety list design.

description: In this work, we study the numerical solution of inverse eigenvalue problems from a machine learning perspective. Two different problems are considered: the inverse Strum-Liouville eigenvalue problem for symmetric potentials and the inverse transmission eigenvalue problem for spherically symmetric refractive indices. Firstly, we solve the corresponding direct problems to produce the required eigenvalues datasets in order to train the machine learning algorithms. Next, we consider several examples of inverse problems and compare the performance of each model to predict the unknown potentials and refractive indices respectively, from a given small set of the lowest eigenvalues. The supervised regression models we use are k-Nearest Neighbours, Random Forests and Multi-Layer Perceptron. Our experiments show that these machine learning methods, under appropriate tuning on their parameters, can numerically solve the examined inverse eigenvalue problems.

description: We propose and demonstrate numerically a measurement scheme for complete reconstruction of the 2D quantum wave function of a Bose-Einstein condensate, amplitude and phase, from a time-of-flight measurement. We identify a fundamental ambiguity present in the measurement of phase structures of high-symmetry excitations (e.g., vortices) and show how to overcome it by allowing for different expansion durations in different directions. We demonstrate this approach with the reconstruction of matter-wave vortices and arrays of vortices.

Surface metrology

description: Surface metrology of components provides valuable information as it applies to their functionality, performance, and integrity. Previous methodologies for surface dimensional analysis integrated a contact “touch-probe” with a coordinate measuring machine (CMM) to gather limited component surface information. Contact methods can be slow and time consuming if full surface information is required. If a customer requires complete surface data in a timely manner, then there exists a driver for utilizing the advantages of non-contact optical metrology. Integration of a 5-axis coordinate measuring machine (CMM) mounted with a Steinbichler white-light optical digitizer allows for automated and fully integrated non-contact, full surface, data acquisition at variable rates of speed depending on accuracy requirements. The methodology proposed will qualify the systems calibrated measuring volume. Current technologies obtain non-contact, full three-dimensional surface data in a format that allows for direct comparison to the computer aided design (CAD) model to yield three-dimensional surface metrology at a high data acquisition rate

description: Bhatnagar-Gross-Krook (BGK) collision kernel is employed in the Boltzmann equation to formulate relativistic dissipative hydrodynamics. In this formulation, we find that there remains freedom of choosing a matching condition that affects the scalar transport in the system. We also propose a new collision kernel which, unlike BGK collision kernel, is valid in the limit of zero chemical potential and derive relativistic first-order dissipative hydrodynamics using it. We study the effects of this new formulation on the coefficient of bulk viscosity.

description: The magnetic subsystem of nabokoite, KCu$_7$(TeO$_4$)(SO$_4$)$_5$Cl, is constituted by copper ions forming a buckled square kagomé lattice decorated by quasi-isolated ions. This combination determines peculiar physical properties of this compound evidenced in electron spin resonance (ESR) spectroscopy, dielectric permittivity $\varepsilon$, magnetization $M$ and specific heat $C_p$ measurements. At lowering temperature, the magnetic susceptibility $χ= M/H$ passes through a broad hump inherent for low-dimensional magnetic systems at about 150 K and a sharp peak at antiferromagnetic phase transition at $T_N = 3.2 $K. The $C_p(T,H)$ curves demonstrate additional peak-like anomaly at $T_{peak}= 5.7$K robust to magnetic field. The latter can be ascribed to low-lying singlet excitations filling the singlet-triplet gap in magnetic excitation spectrum of the square kagomé lattice [J.Richter, O.Derzhko and J.Schnack, Phys. Rev. B \textbf{105} (2022) 144427]. ESR spectroscopy provides indications that antiferromagnetic structure below $T_N$ is non-collinear. Separate issue is the observation of antiferroelectric-type behavior in $\varepsilon$ at low temperatures, which tentatively reduces the symmetry and partially lifts frustration of magnetic interactions of decorating copper ions with buckled square kagomé lattice. These complex thermodynamic and resonant properties signal the presence of two weakly coupled magnetic subsystems in nabokoite, namely a spin-liquid in square kagomé lattice layers and an antiferromagnet represented by decorating ions.
