Codesign Case Study of a Planing Craft with Active Control Systems
Authors: Castro-Feliciano Esteban L. , Sun Jing , Troesch Armin W. , Collette Matthew 
Published: March 2019

This case study presents a novel insight into the design of a codesigned planing craft with an active control system (ACS), along with its potential advantages and disadvantages when compared with a traditionally designed vessel (i.e., a vessel whose geometry is first selected, and then its ACS is implemented). This work has three purposes:present tools a designer can use to codesign a planing craft with its ACS,use these tools to expand the design space and further explore the potential of codesign, andinvestigate the feasibility of having a planing craft with ACS designed to the codesign results found in 2) and compare it with a traditionally designed vessel.
The vessel particulars that are numerically optimized are the beam, dead rise, longitudinal center of gravity (lcg), and two tuning parameters for the ACS's linear quadratic regulator. In the case study, the codesigned vessel had 4% lower drag at the design speed and Sea State (SS) 3, but on lower SS's it had drag savings of 10% and seakeeping improvements of around 40% for the investigated seakeeping metric. The case study suggests that although the codesigned vessel is technically feasible, it would require unconventional hull/deck design—a result which emphasizes the importance of considering the coupling between a planing craft and its ACS early in the concept design.

1. Introduction
In search for a better performing planing craft, a naval architect could consider using an active control system (ACS) on their designs. Although they will encounter published research confirming performance improvements when an ACS is used (Wang 1985; Savitsky 2003; Xi & Sun 2006; Kays et al. 2009; Engle et al. 2011; Hughes & Weems 2011; Rijkens et al. 2011; Shimozono & Kays 2011; Rijkens 2013), literature addressing the concept design process of a planing craft that will have an ACS is, to the best of the authors' knowledge, limited only to the previous work by the authors (Castro-Feliciano et al. 2016, 2018). The work by Castro-Feliciano et al. (2016, 2018) suggests that the benefit from codesigning (as opposed to sequentially designing the vessel geometry and later adding an ACS) can be significant and should be the design methodology followed when designing a planing craft that will have an ACS.

Published: March 2019

AbstractNanostructured biomaterials are extensively explored in clinical imaging and in gene/drug delivery applications. However, limited studies are performed that examine the influence that nanomaterials may have on cell behavior over long time scales at nonlethal concentrations. This study is designed to investigate whether carbon nanotubes are able to augment cell behavior at low concentrations. Single‐walled carbon nanotubes are introduced to neural stem cells at different stages of differentiation at concentrations as low as 5 ng mL−1. Results demonstrate that in this particular cell model, nanotube uptake is mediated by endocytosis. Differentiation is augmented, especially when nanotubes are introduced to cells in an actively dividing state. Significant increases in neuronal cell population are observed over the control specimens. While the mechanisms behind this observation are yet unknown, this study demonstrates that low concentrations of internalized nanomaterials can significantly alter the differentiation profile of a stem cell line.
Strengthening and Expanding Child Services in Low Resource Communities: The Role of Task‐Shifting and Just‐in‐Time Training

Published: March 2019

AbstractIn the United States, the demand for child mental health services is increasing, while the supply is limited by workforce shortages. These shortages are unlikely to be corrected without significant structural changes in how mental health services are provided. One strategy for bridging this gap is task‐shifting, defined as a process by which services that are typically delivered by professionals are moved to individuals with less extensive qualifications or training. Although task‐shifting can increase the size of the workforce, there are challenges related to training new workers. In this paper, we propose Just‐In‐Time Training (JITT) as one strategy for improving task‐shifting efforts. We define JITT as on‐demand training experiences that only include what is necessary, when it is necessary, to promote competent service delivery. We offer a proof of concept from our own work shifting counseling and academic support tasks from school mental health professionals to pre‐baccalaureate mentors, citing lessons learned during our iterative process of JITT development. We conclude with a series of key considerations for scaling up the pairing of task‐shifting and JITT, including expanding the science of JITT and anticipating how task‐shifting and JITT would work within the context of dynamic mental health service systems.

Published: March 2019

AbstractA rhodium‐catalyzed direct heteroarylation of indoles by cleavage of an inert C−C bond of alcohols is reported. This catalytic system exhibits high reactivity and tolerates various functional groups. This reaction provides a tool for the rapid construction of biheteroaryls without pre‐activation of the starting materials. Control experiments were conducted to determine a possible mechanism. This reaction makes a significant contribution to the field of C−C bond activation of alcohols.
Cholecystolithotomy, a new approach to reduce recurrent gallstone ileus
Authors: Rabie Mohamed A. , Sokker Ashraf 
Published: March 2019

The incidence of gallstone ileus (GSI) is increasing. Current treatment options include enterolithotomy with or without cholecystectomy and repair of the biliodigestive fistula. Although most surgeons defer the management of the biliodigestive fistula to avoid the associated morbidity and mortality, this can lead to increased rate of recurrence of GSI by the remaining gallstones. More than 130 cases of recurrent GSI were reported in published works, and the incidence of recurrent GSI is reported to be between 5% and 20%. Some cases of second recurrent attacks have also been reported. Most cases were reported in elderly women with faceted stones during the first 2 months from the first episode of GSI. This article reviews the current treatment options for more than 4,300 reported cases of GSI. A treatment algorithm is recommended based on the severity of the inflammation around the gallbladder, including cholecystolithotomy as a third treatment approach that aims to reduce the risk of recurrent GSI.
Dehydrogenative Synthesis of 2,2′‐Bipyridyls through Regioselective Pyridine Dimerization
Authors: Yamada Shuya , Kaneda Takeshi , Steib Philip , Murakami Kei , Itami Kenichiro 
Published: March 2019

Abstract2,2′‐Bipyridyls have been utilized as indispensable ligands in metal‐catalyzed reactions. The most streamlined approach for the synthesis of 2,2′‐bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium‐catalyzed dehydrogenative synthesis of 2,2′‐bipyridyl derivatives. The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2‐positions. This dimerization method is applicable for challenging substrates such as sterically hindered 3‐substituted pyridines, where the pyridines regioselectively react at the C2‐position. This reaction enables the concise synthesis of twisted 3,3′‐disubstituted‐2,2′‐bipyridyls as an underdeveloped class of ligands.

Published: March 2019

AbstractSeveral genome engineering applications of CRISPR‐Cas9, an RNA‐guided DNA endonuclease, require precision control of Cas9 activity over dosage, timing, and targeted site in an organism. While some control of Cas9 activity over dose and time have been achieved using small molecules, and spatial control using light, no singular system with control over all the three attributes exists. Furthermore, the reported small‐molecule systems lack wide dynamic range, have background activity in the absence of the small‐molecule controller, and are not biologically inert, while the optogenetic systems require prolonged exposure to high‐intensity light. We previously reported a small‐molecule‐controlled Cas9 system with some dosage and temporal control. By photocaging this Cas9 activator to render it biologically inert and photoactivatable, and employing next‐generation protein engineering approaches, we have built a system with a wide dynamic range, low background, and fast photoactivation using a low‐intensity light while rendering the small‐molecule activator biologically inert. We anticipate these precision controls will propel the development of practical applications of Cas9.

AbstractIodine‐promoted direct diamination of α,β‐unsaturated ketone to form two C−N bonds has been developed starting from chalcone and secondary amine. This reaction was performed in THF at 50 °C in the presence of I2 and K2CO3. The protocol is metal‐free, operationally simple and carried out under mild conditions, providing an effective new way for directing diamination reactions.
Robust recursive linear quadratic regulator for wheeled mobile robots based on optical motion capture cameras
Authors: Inoue Roberto S. , Terra Marco H. , Leão Willian M. , Nakai Maurício E. 
Published: March 2019

AbstractIn this paper, we deal with nonholonomic wheeled mobile robots (WMR) modeled as uncertain nonlinear systems. Sources of uncertainties can be due to erroneous estimation of mass, inertia, and center of gravity and due to payload time‐varying. They also can be considered as external disturbances generated from unstructured environments. We are proposing the use of a robust linear quadratic regulator (RLQR) to deal with tracking problems of WMR. In order to guarantee the effectiveness of this control approach, the robot posture is measured through a high‐precision motion capture system. This RLQR encompasses in a unified framework all state and output uncertain parameters of the system and does not depend on any auxiliary parameter to be tuned. It is useful to be used in online applications. Experimental results are presented with a comparative study among the R‐LQR, the nonlinear
control via game theory, and the standard proportional‐derivative controller plus computed torque (PD+CT).
“It kind of fosters a culture of interdependence”: A participatory appraisal study exploring participants' experiences of the democratic processes of a peer‐led organisation

Published: March 2019

AbstractPeer‐led mental health organisations operate through participatory democracy, enabling participants to take an active role in decision making about the running of these organisations. U.K. national policy recommends increased involvement of people accessing statutory mental health services in service development, for example, through co‐production. This study employed a participatory research method to explore participants' perspectives of the democratic processes of a U.K.‐based peer‐led mental health organisation, The Bridge Collective, and the influence of these processes on participant wellbeing. A range of data collection methods were used to gather the perspectives of 16 participants. Participatory thematic analysis identified how the organisations' democratic processes both nurtured and challenged participants' wellbeing. Three main themes captured the influences of the democratic processes on participant wellbeing: (a) negotiating relationships, (b) feeling the responsibility of involvement, and (c) sharing power. The findings identify the value of democratic processes in enabling meaningful social support and empowerment, and also identify the challenges of inclusion and workload management in participatory democracy. These insights may inform the development of co‐production methods and enable The Bridge Collective and other peer‐led organisations to further develop their processes.

Published: March 2019

AbstractLithium/fluorinated carbon (Li/CFx) batteries face the problems of low rate performance and initial voltage delay. Herein, we propose a novel type of fluorinated nanographite as a cathode material for Li/CFx batteries through the direct fluorination of nanographite. The structure of fluorinated nanographite, including crystalline phase, particle size, fluorine content, and the properties of C−F bonding, strongly depend on the fluorination temperature. The fluorinated nanographite prepared at 450 °C (FG‐450) shows the highest specific capacity, 837.4 mAh g−1 at 10 mA g−1, along with a discharge plateau of 2.54 V, responding to an energy density of 2004.5 Wh kg−1. The highlights of the fluorinated nanographite are to deliver high rate performance and overcome the initial voltage delay. FG‐450 can be discharged at a high rate of about 3.6 C, delivering a high power density of 5460 W kg−1 with a remaining energy density of 1030.5 Wh kg−1. The good electrochemical performance of the FG‐450 sample is ascribed to the combined effect of its nanoparticle size, large specific surface area, and continuous stacking porosity.

Published: March 2019

AbstractThe synthesis and characterization of a chemiluminescent metal–organic framework with high porosity is reported. It consists of Zr6O6(OH)4 nodes connected by 4,4′‐(anthracene‐9,10‐diyl)dibenzoate as the linker and luminophore. It shows the topology known for UiO‐66 and is therefore denoted PAP‐UiO. The MOF was not only obtained as bulk material but also as a thin film. Exposure of PAP‐UiO as bulk or film to a mixture of bis‐(2,4,6‐trichlorophenyl) oxalate, hydrogen peroxide, and sodium salicylate in a mixture of dimethyl and dibutyl phthalate evoked strong and long lasting chemiluminescence of the PAP‐UiO crystals. Time dependent fluorescence spectroscopy on bulk PAP‐UiO and, for comparison, on dimethyl 4,4′‐(anthracene‐9,10‐diyl)dibenzoate provided evidence that the chemiluminescence originates from luminophores being part of the PAP‐UiO, including the luminophores inside the crystals.

Published: March 2019

SummaryThe paper presented here entails technique that is based upon Sorensen's similarity coefficient as well as the Sorensen‐ Single Linkage Clustering (SLC) algorithm, which essentially is a hybrid clustering approach that has been deployed here to show issue related to cell formation during the process of cellular engineering. In the following paper and study that has been presented here, the suggested hybrid algorithm comparison has been drawn versus the existing clustering algorithms and their performances have been compared specifically the MOD‐SLC modified single linkage or SLC also known as the single linkage clustering algorithm. The Sorensen‐SLC technique and the inferences drawn on the same show that it performs comparatively better when compared with the MOD‐SLC and SLC algorithms. Additionally, the computation that is necessary for this hybrid algorithm is absolutely a bare minimal and the computation processing is effective and easy.
An efficient model for quantifying the interaction between structural properties of software and hardware in the ARM big.LITTLE architecture

Published: March 2019

SummaryHeterogeneous architectures offer the opportunity to achieve high performance and energy efficiency by selecting appropriate cores for the execution of ever‐changing software applications. Appropriate core selection depends on the interaction between the structural properties of the software and the hardware that influences the performance of the software. We propose a model for efficient core selection when executing software on ARM's big.LITTLE heterogeneous architecture. It features a metric based on the correlation between the performance and the number of last‐level data cache (LLC) misses on a big and a LITTLE core. Additionally, our model defines a soft threshold in terms of the number of LLC misses, which determines efficient core selection. We verify the model using stress and variable workload benchmarks as well as two popular high‐throughput applications for mutlicore targets, namely, HEVC and LDPC decoders, profiled with X‐Mem, Linux perf, and PMCTrack dynamic tools. Results show that our model can be used for efficient core selection with a relatively small error probability.
Direct and indirect effects of land‐use intensification on ant communities in temperate grasslands
Authors: Heuss Lisa , Grevé Michael E. , Schäfer Deborah , Busch Verena , Feldhaar Heike 
Published: March 2019

AbstractLand‐use intensification is a major driver of local species extinction and homogenization. Temperate grasslands, managed at low intensities over centuries harbored a high species diversity, which is increasingly threatened by the management intensification over the last decades. This includes key taxa like ants. However, the underlying mechanisms leading to a decrease in ant abundance and species richness as well as changes in functional community composition are not well understood. We sampled ants on 110 grassland plots in three regions in Germany. The sampled grasslands are used as meadows or pastures, being mown, grazed or fertilized at different intensities. We analyzed the effect of the different aspects of land use on ant species richness, functional trait spaces, and community composition by using a multimodel inference approach and structural equation models. Overall, we found 31 ant species belonging to 8 genera, mostly open habitat specialists. Ant species richness, functional trait space of communities, and abundance of nests decreased with increasing land‐use intensity. The land‐use practice most harmful to ants was mowing, followed by heavy grazing by cattle. Fertilization did not strongly affect ant species richness. Grazing by sheep increased the ant species richness. The effect of mowing differed between species and was strongly negative for Formica species while Myrmica and common Lasius species were less affected. Rare species occurred mainly in plots managed at low intensity. Our results show that mowing less often or later in the season would retain a higher ant species richness—similarly to most other grassland taxa. The transformation from (sheep) pastures to intensively managed meadows and especially mowing directly affects ants via the destruction of nests and indirectly via loss of grassland heterogeneity (reduced plant species richness) and increased soil moisture by shading of fast‐growing plant species.
The basic examination of the magnetic shielding structure to use for a magnetic rotation angle sensor
Authors: Musha Takeshi , Inujima Hiroshi 
Published: March 2019

AbstractThe magnetic rotation angle sensor has more merits such as small‐sized, low‐cost, and the low‐power consumption than the optical sensor. But the magnetic rotation angle sensor has the demerit to be weak to the disturbance magnetic field applied from outside the sensor, so the magnetic rotation angle sensor needs magnetic shielding structure. We proposed the magnetic shielding structure of the parallel plate type that is the simpler technique to the magnetic shielding structure of enclosing the whole sensor with the magnetic substance. We confirmed that the parallel plate type has almost the same shielding performance as the magnetic shielding structure of enclosing the whole sensor with the magnetic substance at the magnetic detecting device. We have made a prototype and evaluated angle detection error with the disturbance magnetic field. As a result, we confirmed that the error is 0.06° when 10 mT disturbance magnetic fields hang over the sensor.
