Reducing avoidable deaths from failure to rescue: a discussion paper.
Venue: British journal of nursing

This article proposes a radical new approach to the monitoring and governance of services, and the education and training of nurses to meet 'failure to rescue' requirements.  Healthcare policy in the UK that seeks to ensure safe and effective services for the acutely ill has largely failed, resulting in adult patients dying unnecessarily. Despite grand rhetoric, UK governments have distanced themselves from implementation, resulting in patchy localised developments and creating inconsistent service responses.  This article draws on a review of research and UK policy literature and best international practice to propose a new national framework approach that combines competency development, governance and performance monitoring to address 'failure to rescue' shortcomings.  Paramount is a nationally agreed and fit for purpose competency tool using simulation to assess staff in order to improve recognition of the deteriorating patient. Service improvements should include increased investment in telemedicine; service performance should be communicated through publicly available ratings and overseen by patient panels; and governance will require strengthening through enhanced Care Quality Commission/Monitor input, which should be linked to the maintenance of foundation trust status.  Health professional bodies, regulators, providers and the Government must work together to strengthen the safety and effectiveness of acute services. This will require investment in staff competency and enhancement of the governance to ensure services consistently meet public expectations and reduce unnecessary deaths.
Multi contact protocol constrained collision avoidance for autonomous marine vehicles

The field of autonomous collision avoidance has continued to advance in many areas including sensory and perception, navigation, payload integration, and collision avoidance. The advances in collision avoidance, however, have largely focused on iterative changes to the velocity obstacle an algorithm that inherently loses important collision avoidance information key to replicating a human like decision space. This thesis examines algorithms that generalize the traditional velocity obstacle into a multi threshold based approach that more realistically represent and evaluate human ship driving practices. Novel protocol constrained collision avoidance evaluation algorithms are proposed including the ability to perform both on line and post mission analysis of both robots and humans. These algorithms become especially important when considering complex missions of competing objectives in a contact dense, protocol constrained collision avoidance environment. Introduction of competing performance metrics consistent with human ship driving practices allows autonomous collision avoidance algorithm designers to consider previously unexplored tradespaces. On water results of up to five simultaneously interacting autonomous vessels validate the collision avoidance algorithms using four key areas of evaluation: spatial efficiency, temporal efficiency, protocol compliance, and safety. Testing of 10 complex scenarios totaled over 6,150 vehicle pair on water encounters. Human robot field experimentation demonstrated autonomous collision avoidance performance under conflicting protocol requirements of COLREGS while interacting with human driven vessels. An autonomous collision avoidance "road test" framework is proposed to incorporate testing of arbitrary collision avoidance algorithms both in the field and in simulation.
Nonstoichiometric acid base reaction as reliable synthetic route to highly stable CH3NH3PbI3 perovskite film
Venue: Nature communications

Perovskite solar cells have received worldwide interests due to swiftly improved efficiency but the poor stability of the perovskite component hampers the device fabrication under normal condition. Herein, we develop a reliable nonstoichiometric acid base reaction route to stable perovskite films by intermediate chemistry and technology. Perovskite thin film prepared by nonstoichiometric acid base reaction route is stable for two months with negligible PbI2 impurity under ~65% humidity, whereas other perovskites prepared by traditional methods degrade distinctly after 2 weeks. Route optimization involves the reaction of PbI2 with excess HI to generate HPbI3, which subsequently undergoes reaction with excess CH3NH2 to deliver CH3NH3PbI3 thin films. High quality of intermediate HPbI3 and CH3NH2 abundance are two important factors to stable CH3NH3PbI3 perovskite. Excess volatile acid/base not only affords full conversion in nonstoichiometric acid base reaction route but also permits its facile removal for stoichiometric purification, resulting in average efficiency of 16.1% in forward/reverse scans.
Enhanced performance of perovskite solar cells by modulating the Lewis acid base reaction.
Venue: Nanoscale

The Lewis acid base reaction between PbI2 and solvent molecules is popular in fabricating PbI2 films by a two step method for making perovskite solar cells. Here, we control the microstructure of PbI2 films through modulating the Lewis acid base reaction by adding a small amount of N methyl pyrrolidone into PbI2/DMF solution. PbI2 films with excellent crystallinity and full coverage are fabricated by spin coating the mixed solution on the substrate, which leads to high quality perovskite layers with low recombination rate and high efficiency for carrier transfer. As a result, the power conversion efficiency of the best perovskite solar cells increases from 13.3% to 17.5%
Incorporation of Alkylamine into Metal Organic Frameworks through a Bronsted Acid Base Reaction for CO2 Capture.
Venue: ChemSusChem

The escalating atmospheric CO2 concentration is one of the most urgent environmental concerns of our age. To effectively capture CO2 various materials have been studied. Among them, alkylamine modified metal organic frameworks (MOFs) are considered to be promising candidates. In most cases, alkylamine molecules are integrated into MOFs through the coordination bonds formed between open metal sites (OMSs) and amine groups. Thus, the alkylamine density, as well as the corresponding CO2 uptake in MOFs, are severely restricted by the density of OMSs. To overcome this limit, other approaches to incorporating alkylamine into MOFs are highly desired. We have developed a new method based on Bronsted acid base reaction to tether alkylamines into Cr MIL 101 SO3 H for CO2 capture. A systematic optimization of the amine tethering process was also conducted to maximize the CO2 uptake of the modified MOF. Under the optimal amine tethering condition, the obtained tris(2 aminoethyl)amine functionalized Cr MIL 101 SO3 H (Cr MIL 101 SO3 H TAEA) has a cyclic CO2 uptake of 2.28 mmol g 1 at 150 mbar and 40 degC, and 1.12 mmol g 1 at 0.4 mbar and 20 degC. The low cost starting materials and simple synthetic procedure for the preparation of Cr MIL 101 SO3 H TAEA suggest that it has the potential for large scale production and practical applications.
Electrochemically Driven Surface Confined Acid/Base Reaction for an Ultrafast H( Supercapacitor.
Venue: Journal of the American Chemical Society

We discovered an organic weak acid, 3,4,9,10 perylene tetracarboxylic acid (PTCA) confined on the electrode surface, revealing a reversible and ultrafast protonation/deprotonation non Faradaic process but exhibiting analogous voltammetric peaks (capacitive peaks) A further synthesized PTCA graphene supramolecular nanocomplex discloses a wide voltage window (1.2 V) and ultrahigh specific capacitance up to 143 F g( 1) at an ultrafast charge discharge density of 1000 A g( 1) (at least 1 order of magnitude faster than present speeds) The capacitance retention maintained at 73% after 5000 cycles. This unique capacitive voltammetric behavior suggests a new type of charge storage modes, which may offer a way for overcoming the present difficulties of supercapacitors.
Acid Base Bifunctional Shell Cross Linked Micelle Nanoreactor for One Pot Tandem Reaction

Shell cross linked micelles (SCMs) containing acid sites in the shell and base sites in the core are prepared from amphiphilic poly(2 oxazoline) triblock copolymers. The materials are utilized as two chamber nanoreactors for a prototypical acid base bifunctional tandem deacetalization nitroaldol reaction. The acid and base sites are localized in different regions of the micelle, allowing the two steps in the reaction sequence to largely proceed in separate compartments, akin to the compartmentalization that occurs in biological systems.
Robust formation control applying model predictive control to multi agent system by sharing disturbance information with UAVs
Venue: 2016 55th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE)

A safety technology about unmanned aerial vehicles(UAVs) attracts a lot of attention. This paper presents a robust formation control method for multi agent system (MAS) to suppress the influence of disturbance and maintain the formation robustly by sharing the disturbance information. This paper estimates the disturbance by the disturbance observer. UAVs share these disturbance information using network of MAS. The inputs are calculated by model predictive control(MPC) that predicts the future motion of each UAV considering a shared disturbance information. UAVs share the disturbance information and the future motion of UAVs predicted by MPC using network of MAS. The proposed method achieves the robust formation control to consider these future information in MPC. This paper verifies the validity of proposed method via simulation.
The Experimental Research of Color Measurements with Spectrophotometer

To study the performance of the three spectrophotometers: Spectroeye, i1, and eXact, the spectral reflectance of X rite ColorChecker(r) was measured with them. By computing the standard deviation of spectral reflectance and color difference \Delta E_{ab} the stability and repeatability characteristics of the three color measuring instruments were analyzed. The results showed that the standard deviations of spectral reflectance are less than 0.001. The average color difference between the measurements and reference data is less than {2\varDelta }E_{ab} The color difference between each two spectrophotometers is about {1\varDelta }E_{ab} The measurement error between the spectrophotometer is acceptable, so we could choose corresponding instrument according to the range of measurement wavelength.
The Novel Object and Unusual Name (NOUN) Database: A collection of novel images for use in experimental research
Venue: Behavior research methods

Many experimental research designs require images of novel objects. Here we introduce the Novel Object and Unusual Name (NOUN) Database. This database contains 64 primary novel object images and additional novel exemplars for ten basic and nine global level object categories. The objects' novelty was confirmed by both self report and a lack of consensus on questions that required participants to name and identify the objects. We also found that object novelty correlated with qualifying naming responses pertaining to the objects' colors. The results from a similarity sorting task (and a subsequent multidimensional scaling analysis on the similarity ratings) demonstrated that the objects are complex and distinct entities that vary along several featural dimensions beyond simply shape and color. A final experiment confirmed that additional item exemplars comprised both sub and superordinate categories. These images may be useful in a variety of settings, particularly for developmental psychology and other research in the language, categorization, perception, visual memory, and related domains.
Low Power Wearable ECG Monitoring System for Multiple Patient Remote Monitoring
Venue: IEEE Sensors Journal

Many devices and solutions for remote electrocardiogram (ECG) monitoring have been proposed in the literature. These solutions typically have a large marginal cost per added sensor and are not seamlessly integrated with other smart home solutions. Here, we propose an ECG remote monitoring system that is dedicated to non technical users in need of long term health monitoring in residential environments and is integrated in a broader Internet of Things (IoT) infrastructure. Our prototype consists of a complete vertical solution with a series of advantages with respect to the state of the art, considering both the prototypes with integrated front end and prototypes realized with off the shelf components: 1) ECG prototype sensors with record low energy per effective number of quantized levels; 2) an architecture providing low marginal cost per added sensor/user; and 3) the possibility of seamless integration with other smart home systems through a single IoT infrastructure.
Fully Textile, PEDOT:PSS Based Electrodes for Wearable ECG Monitoring Systems
Venue: IEEE Transactions on Biomedical Engineering

To evaluate a novel kind of textile electrodes based on woven fabrics treated with PEDOT:PSS, through an easy fabrication process, testing these electrodes for biopotential recordings.  Fabrication is based on raw fabric soaking in PEDOT:PSS using a second dopant, squeezing and annealing. The electrodes have been tested on human volunteers, in terms of both skin contact impedance and quality of the ECG signals recorded at rest and during physical activity (power spectral density, baseline wandering, QRS detectability, and broadband noise)  The electrodes are able to operate in both wet and dry conditions. Dry electrodes are more prone to noise artifacts, especially during physical exercise and mainly due to the unstable contact between the electrode and the skin. Wet (saline) electrodes present a stable and reproducible behavior, which is comparable or better than that of traditional disposable gelled Ag/AgCl electrodes.  The achieved results reveal the capability of this kind of electrodes to work without the electrolyte, providing a valuable interface with the skin, due to mixed electronic and ionic conductivity of PEDOT:PSS. These electrodes can be effectively used for acquiring ECG signals.  Textile electrodes based on PEDOT:PSS represent an important milestone in wearable monitoring, as they present an easy and reproducible fabrication process, very good performance in wet and dry (at rest) conditions and a superior level of comfort with respect to textile electrodes proposed so far. This paves the way to their integration into smart garments.
Characterization of edible films of Swartzia burchelli phosphated starches and development of coatings for post harvest application to cherry tomatoes

The market demand for corn starch and cassava continues to increase because of their use in edible applications, their biodegradable nature, and other appealing properties. As a result, there is a need to identify alternative starch sources, for example, the seeds of S. burchelli, with the potential to be modified for use in post harvest applications. Therefore, this study aimed to develop and characterize edible films based on the starch phosphates of the seeds of S. burchelli, with the specific aim to apply these starches to cherry tomatoes for post harvest conservation. After extraction, the starch was phosphorylated with sodium tripolyphosphate (STP) in different concentrations and times according to a 2 x 2 factorial design with additional treatment (native starch) After modification, the starch phosphates were selected for the preparation of edible films using glycerol as a plasticizer, in proportions of 5, 10, 15 and 20% for each selected starch. The films were measured for thickness, permeability to water vapor and solubility in water. According to their permeability values, 4 films were selected for application in the coverage of cherry tomatoes. The conservation of cherry tomatoes with and without coverage was studied over 8 evaluation times (up to 21 days) at 10+ 2 degC and 80+ 5% relative humidity. The weight loss, soluble solids, titratable acidity, maturation index, and firmness were measured every 3 days during storage. The starch phosphates showed a phosphorus content within that established by standards, such that the resulting films are acceptable for use in food for human consumption. The edible films presented with an acceptable appearance and without the development of cracks. The concentration of glycerol and the type of starch influenced the characteristics of the films, increasing the permeability and reducing the water solubility of the various edible films. The best result obtained regarding the conservation of cherry tomatoes was observed for fruits with edible coatings of greater permeability to water vapor; such fruits exhibited only a slight decline in firmness during storage compared with the control. It can be concluded that the modification performed on the starch and the glycerol concentration positively influenced the properties of the edible films, allowing for optimal use in post harvest applications. Similarly, the edible coatings conferred better appearance to the fruits, maintaining their maturation index and firmness during the experimental period and providing better post harvest storage conditions for the cherry tomatoes.

On Chip Multiple Colliding Pulse Mode Locked Semiconductor Laser
Venue: Journal of Lightwave Technology

We report for the first time to the best of our knowledge, an on chip multiple colliding pulse mode locked semiconductor laser source. The device structure is fully integrated, replacing cleaved facet mirrors by using multimode interference reflectors; this allows us to precisely control the location of the saturable absorbers within the cavity length, which is critical to achieve the multiple colliding regime. In this paper, we succeeded to achieve this regime generating a repetition rate at four times the fundamental round trip frequency, demonstrating a repetition rate within the millimeter wave frequency range, at 100 GHz using a 25 GHz resonator cavity length. We also demonstrate the advantage of having the signal on chip including a boost semiconductor optical amplifier in order to increase the output optical power. This novel structure was fabricated on a generic InP photonic integrated technology through a multi project wafer run.
Celebrity Credibility on Social Media: A Conditional Process Analysis of Online Self Disclosure Attitude as a Moderator of Posting Frequency and Parasocial Interaction

This study investigated factors predicting perception of celebrity credibility on social networking sites. Specifically, we evaluated a theoretical model whereby parasocial interaction mediates the association between posting frequency and credibility, with online self disclosure attitude moderating these associations. Results supported this mediation, with the indirect effects for group and personal identification (but not interest or problem solving ability) contingent on the user's online self disclosure attitude. Among other implications, findings suggest different forms of PSI may function differently vis a vis credibility, as well as commend future investigation of attitudinal variables that may moderate perception of online messages.
Effects of Facebook Fan Page Users' Social Capital Needs, Innovativeness and Self Presentation Needs on Interactive Behavior: Brand Identification as a Moderator Variable

This study focuses on the effects of Facebook fan pages which have recently risen in value as a unique, online communication channel.  A survey was conducted using a sample of 310 high school aged men and women who have ever used a Facebook fan page.  First, the results of the analysis found that Facebook users' perceptions (their social capital needs, innovativeness and self presentation needs) indirectly affected moderator variables, such as brand identification. Next, the significant gender differences were analyzed. Any independent variables of both men and women turned out to not significantly affect their interactive behavior.  This study suggests that the psychological tendencies of Facebook fan page users affect their interactive behavior via moderator variables, such as brand identification. Theoretical and practical implications are discussed, based on the results from the present study.
Z type control of populations for Lotka Volterra model with exponential convergence.
Venue: Mathematical biosciences

The population control of the Lotka Volterra model is one of the most important and widely investigated issues in mathematical ecology. In this study, assuming that birth rate is controllable and using the Z type dynamic method, we develop Z type control laws to drive the prey population and/or predator population to a desired state to keep species away from extinction and to improve ecosystem stability. A direct controller group is initially designed to control the prey and predator populations simultaneously. Two indirect controllers are then proposed for prey population control and predator population control by exerting exogenous measure on another species. All three control laws possess exponential convergence performances. Finally, the corresponding numerical simulations are performed. Results substantiate the theoretical analysis and effectiveness of such Z type control laws for the population control of the Lotka Volterra model.

Extremal bootstrapping: go with the flow

A bstractThe extremal functional method determines approximate solutions to the constraints of crossing symmetry, which saturate bounds on the space of unitary CFTs. We show that such solutions are characterized by extremality conditions, which may be used to flow continuously along the boundaries of parameter space. Along the flow there is generically no further need for optimization, which dramatically reduces computational requirements, bringing calculations from the realm of computing clusters to laptops. Conceptually, extremality sheds light on possible ways to bootstrap without positivity, extending the method to non unitary theories, and implies that theories saturating bounds, and especially those sitting at kinks, have unusually sparse spectra. We discuss several applications, including the first high precision bootstrap of a non unitary CFT.
