Estimated Detonation Velocities for TKX‐50, MAD‐X1, BDNAPM, BTNPM, TKX‐55, and DAAF using the Laser–induced Air Shock from Energetic Materials Technique
Authors: Gottfried Jennifer L. , Klapötke Thomas M. , Witkowski Tomasz G. 
Published: February 2017

AbstractSince new energetic materials are initially produced in very small quantities for both safety and cost reasons, laboratory‐scale methods for characterizing their performance are essential for determining the most promising candidates for scale‐up. Laser‐induced air shock from energetic materials (LASEM) is a promising new method for estimating the detonation velocity of novel explosives using milligram amounts of material, while simultaneously investigating their high temperature chemical reactions. LASEM has been applied to 6 new explosives for the first time: TKX‐50, MAD−X1, BDNAPM, BTNPM, TKX‐55, and DAAF. Emission spectroscopy of the laser excited materials revealed the formation of the high pressure bands of C2 during the ensuing exothermic reactions. The low thermal sensitivity of the materials also led to unusual laser‐material interactions, visualized with high‐speed video. The estimated detonation velocities for the 6 explosives were compared to predicted values from EXPLO5 and CHEETAH. The LASEM results suggest that TKX‐55, BDNAPM, and BTNPM have higher detonation velocities than predicted by the thermochemical codes, while the estimated detonation velocities for MAD−X1 and TKX‐50 are slightly lower than those predicted.

AbstractA few of novel, thermally stable, nitro‐substituted calixanes were successfully synthesized and their spatial configurations also were confirmed. 14,16,34,36,54,56,74,76‐octanitro‐2,4,6,8‐tetraoxa‐1,3,5,7(1,3)‐tetraben‐zenacyclooctaphane (7) as heat‐resistant explosives can be prepared by means of a facile synthetic produced and shows outstanding properties (good thermal stability and high thermal decomposition temperature and energetic performances). It has also been pointed out that the production of compound 7 is very easy on a large scale. All target compounds was characterized by single‐crystal X‐ray diffraction, NMR and elemental analysis, TG and DSC. In this paper, the macrocyclic compounds are introduced into the study as heat‐resistant explosives firstly, which will change the past stagnant situation!
Time‐ and State‐Dependent Input Delay‐Compensated Bang‐Bang Control of a Screw Extruder for 3D Printing
Authors: Diagne Mamadou , Bekiaris‐Liberis Nikolaos , Krstic Miroslav 
Published: February 2017

SummaryIn this paper, a delay‐compensated bang‐bang control design methodology for the control of the nozzle output flow rate of screw extruder‐based three‐dimensional printing processes is developed. A geometrical decomposition of the screw extruder in a partially and a fully filled regions allows to describe the material convection in the extruder chamber by a one‐dimensional hyperbolic partial differential equation (PDE) coupled with an ordinary differential equation. After solving the hyperbolic PDE by the method of characteristics, the coupled PDE–ordinary differential equation's system is transformed into a nonlinear state‐dependent input delay system. The aforementioned delay system is extended to the non‐isothermal case with the consideration of periodic fluctuations acting on the material's convection speed, which represent the process variabilities due to temperature changes in the extruder chamber, resulting to a nonlinear system with an input delay that simultaneously depends on the state and the time variable. Global exponential stability of the nonlinear delay‐free plant is established under a piecewise exponential feedback controller that is designed. By combining the nominal, piecewise exponential feedback controller with nonlinear predictor feedback, the compensation of the time‐dependent and state‐dependent input delay of the extruder model is achieved. Global asymptotic stability of the closed‐loop system under the bang‐bang predictor feedback control law is established when certain conditions related to the extruder design and the material properties, as well as to the magnitude and frequency of the materials transport speed variations, are satisfied. Simulations results are presented to illustrate the effectiveness of the proposed control design. Copyright © 2017 John Wiley & Sons, Ltd.
Formation tracking control for multiple rigid bodies on matrix Lie groups: A system decomposition approach
Authors: Sun Junyong , Geng Zhiyong 
Published: February 2017

SummaryThis paper addresses the finite‐time formation tracking control problem for multiple rigid bodies whose dynamics are defined on the matrix Lie groups, including the special Euclidean group SE(2),SE(3) as specific cases. The reference trajectory in a form of rotational and translational motions is generated offline in advance as the virtual leader for tracking. Moreover, the formation time is specified according to the task, and the desired formation shape is given a priori with respect to the virtual leader. By virtue of the system decomposition approach, intrinsic formation tracking laws are derived for arbitrary initial velocities for the rigid bodies. The tracking controllers are intrinsic meaning that the dynamics and controllers are developed in the body‐fixed frame without a global reference frame. Moreover, based on the geometric convex combination on SE(3), the result is extended to the distributed case where only the neighboring agents' state are used. Two numerical simulations on SE(2) and SE(3) are given respectively to illustrate the validity and robustness of the proposed controllers. Copyright © 2017 John Wiley & Sons, Ltd.
A comprehensive framework for modeling requirements of CSCW systems
Authors: Teruel Miguel A. , Navarro Elena , López‐Jaquero Víctor , Montero Francisco , González Pascual 
Published: February 2017

AbstractAs in any other system, an accurate requirements specification is essential to developing a collaborative system, which has special kinds of requirements that are hard to specify by means of current Requirements Engineering techniques. The Collaborative Systems Requirement Modeling Framework (CSRMF) was developed to address this problem; the original Collaborative Systems Requirement Modeling Language was extended and modeled to properly deal with collaboration and awareness requirements. The developed CSRMF framework consists of 3 components: an Requirements Engineering modeling language able to represent collaboration among users as well as awareness needs, a set of design guidelines that drive Computer Supported Cooperative Work system specification by means of 5 different types of diagrams, and a supporting computer‐aided software engineering tool to specify and validate Computer Supported Cooperative Work system requirements. CSRMF provides Requirements Engineers with a complete solution to the specification of awareness‐demanding collaborative systems, as they can now take advantage of a language and a set of guidelines supported by a tool to guide them in specifying system requirements.

Published: February 2017

ABSTRACTDespite the advantages that the development of new technologies has brought to our lives, it is also true that the problematic use of technology can have negative effects on some people, as the prevalence of nomophobia, defined as the fear and anxiety of being unreachable via one's mobile phone. While some authors are beginning to study the relationship of nomophobia with variables such as age, no investigation has yet been carried out into psychological variables. Our study contributes to the literature by looking at personality, self‐esteem, gender and age as predictors of nomophobia, evaluated by the Mobile Phone Involvement Questionnaire (MPIQ). The study comprised 242 Spanish students (46.7% men and 53.3% women; 49.2% studying for a high school certificate and 50.8% for a university degree). Multiple regressions were conducted, finding that self‐esteem, extraversion, conscientiousness and emotional stability predict nomophobia. Finally, we discuss these results and provide suggestions for future research.

Published: February 2017

AbstractIntrauterine growth restriction (IUGR) is one of the most common causes of perinatal mortality and morbidity. White matter and neuronal injury are major pathophysiological features of the IUGR neonatal brain. GABAA (γ‐aminobutyric acid type A) receptors have been shown to play a role in oligodendrocyte differentiation and proliferation in the neonatal brain and may be a key factor in white matter injury and myelination in IUGR neonates. Whether there are impairments to the GABAergic system and neuronal cytoskeleton in IUGR brain has yet to be elucidated. This study aims to examine GABAA receptor α1 and α3 subunit protein expression and distribution in parietal cortex and hippocampus of the IUGR piglet at four different ages (term = 115 d – days gestational age), 100 d, 104 d, birth (postnatal day 0–P0) and P7 and to examine neuronal and myelination patterns. Significant alterations to GABAA receptor α1 and α3 protein expression levels were observed in the IUGR piglet brain of P7 IUGR piglets with significantly greater α3 expression compared to α1 expression in the hippocampus while there was virtually no difference between the two subunits in the parietal cortex. However a significantly lower α1/α3 ratio was evident in P7 IUGR cortex when compared with P7 NG cortex. Neuronal somatodendrites studied using MAP2 immunohistochemistry showed reduced and disrupted somatodendrites while MBP immunolabelling showed loss of axonal fibres from gestational day 104 d through to P7. These findings provide insights into the effects of IUGR on the development of the GABA system, altered developmental maturation of GABAA receptor subunit expression in the IUGR brain may influence myelination and may partly explain the cognitive disabilities observed in IUGR. Understanding the mechanisms behind grey and white matter injury in the IUGR infant is essential to identifying targets for treatments to improve long‐term outcomes for IUGR infants.
Surgical treatment of liver cirrhosis and hypersplenism with huge accessory spleen – A case report
Authors: Zhuang Bo , Yu Shian , Jin Ruyan , Gong Daojun 
Published: February 2017

Abstract

Introduction
Accessory spleens which are common and separate from the main body of the spleen, are the healthy splenic tissues and usually smaller than 2cm. Here, we report a case of liver cirrhosis and hypersplenism with a huge accessory spleen. This case report and literature review describes the management of the enlarged accessory spleen.

Presentation of case
We report the case of a 47-year-old man who presented with discomfort in the left upper abdomen and hypodynamia for more than 3 months. The color Doppler sonography and abdominal contrast-enhanced computed tomography (CT) revealed a well-marginated ovoid mass, approximately 13.0 cm × 8.0 cm × 5.0cm between stomach and spleen. The patient underwent the laparoscopic splenectomy because of liver cirrhosis and hypersplenism. The result that the mass is the enlarged accessory spleen was confirmed by pathological diagnosis. Clinical symptoms were relieved in 1 month after operation.

Discussion
Accessory spleens could enlarge to more than 10cm in patients with liver cirrhosis. CT and laparoscope can be used for preoperative, intraoperative diagnosis of accessory spleens. Laparoscopic splenectomy associated huge accessory splenectomy is one of the effective treatments of patients with liver cirrhosis and hypersplenism.

Conclusion
Because such a large accessory spleen is rare, to a certain extent, it renders diagnosis more difficult. If we are familiar with its character, unnecessary treatment can be avoided.

AbstractIntroductionThe International Working Group recommended the Free and Cued Selective Reminding Test (FCSRT) as a sensitive detector of the amnesic syndrome of the hippocampal type in typical Alzheimer's disease (AD). But does it differentiate AD from other neurodegenerative diseases?MethodsWe assessed the FCSRT and cerebrospinal fluid (CSF) AD biomarkers in 992 cases. Experts, blinded to biomarker data, attributed in 650 cases a diagnosis of typical AD, frontotemporal dementia, posterior cortical atrophy, Lewy body disease, progressive supranuclear palsy, corticobasal syndrome, primary progressive aphasias, “subjective cognitive decline,” or depression.ResultsThe FCSRT distinguished typical AD from all other conditions with a sensitivity of 100% and a specificity of 75%. Non‐AD neurodegenerative diseases with positive AD CSF biomarkers (“atypical AD”) did not have lower FCSRT scores than those with negative biomarkers.DiscussionThe FCSRT is a reliable tool for diagnosing typical AD among various neurodegenerative diseases. At an individual level, however, its specificity is not absolute. Our findings also widen the spectrum of atypical AD to multiple neurodegenerative conditions.

AbstractIntroductionFindings for genetic correlates of late‐onset Alzheimer's disease (LOAD) in studies that rely solely on clinic visits may differ from those with capacity to follow participants unable to attend clinic visits.MethodsWe evaluated previously identified LOAD‐risk single nucleotide variants in the prospective Adult Changes in Thought study, comparing hazard ratios (HRs) estimated using the full data set of both in‐home and clinic visits (n = 1697) to HRs estimated using only data that were obtained from clinic visits (n = 1308). Models were adjusted for age, sex, principal components to account for ancestry, and additional health indicators.ResultsLOAD associations nominally differed for 4 of 21 variants; CR1 and APOE variants were significant after Bonferroni correction.DiscussionEstimates of genetic associations may differ for studies limited to clinic‐only designs. Home visit capacity should be explored as a possible source of heterogeneity and potential bias in genetic studies.

AbstractObjectivesThe objective of this study was to quantify the potential retail pharmacy vaccine administration capacity and its possible impact on pandemic influenza vaccine uptake.MethodsWe developed a discrete event simulation model by use of ExtendSim software (Imagine That Inc, San Jose, CA) to forecast the potential effect of retail pharmacy vaccine administration on total weekly vaccine administration and the time needed to reach 80% vaccination coverage with a single dose of vaccine per person.ResultsResults showed that weekly national vaccine administration capacity increased to 25 million doses per week when retail pharmacist vaccination capacity was included in the model. In addition, the time to achieve 80% vaccination coverage nationally was reduced by 7 weeks, assuming high public demand for vaccination. The results for individual states varied considerably, but in 48 states the inclusion of pharmacies improved time to 80% coverage.ConclusionsPharmacists can increase the numbers of pandemic influenza vaccine doses administered and reduce the time to achieve 80% single-dose coverage. These results support efforts to ensure pharmacist vaccinators are integrated into pandemic vaccine response planning. (Disaster Med Public Health Preparedness. 2017;11:587–593)

BACKGROUNDInfants and young children are frequently colonized with C. difficile but rarely have symptomatic disease. However, C. difficile testing remains prevalent in this age group.OBJECTIVETo design a computerized provider order entry (CPOE) alert to decrease testing for C. difficile in young children and infants.DESIGNAn interventional age-targeted before-after trial with comparison groupSETTINGMonroe Carell Jr. Children’s Hospital at Vanderbilt University, Nashville, Tennessee.PATIENTSAll children seen in the inpatient or emergency room settings from July 2012 through July 2013 (pre-CPOE alert) and September 2013 through September 2014 (post-CPOE alert)INTERVENTIONIn August of 2013, we implemented a CPOE alert advising against testing in infants and young children based on the American Academy of Pediatrics recommendations with an optional override. We further offered healthcare providers educational seminars regarding recommended C. difficile testing.RESULTSThe average monthly testing rate significantly decreased after the CPOE alert for children 0–11 months old (11.5 pre-alert vs 0 post-alert per 10,000 patient days; P<.001) and 12–35 months old (61.6 pre-alert vs 30.1 post-alert per 10,000 patients days; P<.001), but not for those children ≥36 months old (50.9 pre-alert vs 46.4 post-alert per 10,000 patient days; P=.3) who were not targeted with a CPOE alert. There were no complications in those children who testing positive for C. difficile.CONCLUSIONSThe average monthly testing rate for C. difficile for children <35 months old decreased without complication after the use of a CPOE alert in those who tested positive for C. difficile.Infect Control Hosp Epidemiol 2017;38:542–546
MAKING MONEY IN THE STATE: NORTH KOREA'S PSEUDO-STATE ENTERPRISES IN THE EARLY 2000s

Published: February 2017

AbstractIn the 1990s, a part of the North Korean economy underwent a process of marketization and de facto privatization. While largely spontaneous, this process was eerily reminiscent of developments in other post-Communist countries in Eastern Europe. One of the results was the emergence of a new entrepreneurial class, a nascent bourgeoisie. In order to overcome the obstacles that arose from the lack of any legal framework for their activities, they often chose to register their enterprises with state agencies, creating what we call Pseudo-state Enterprises (PSEs). Utilizing an agency theory approach, with particular emphasis on property rights and contracting problems, this article traces the origin of the PSE, their interaction with the state, how they are managed and the challenges they face. The article is based on refugee interviews with five North Koreans involved with the PSE-related activities in nine entities covering a range of different sectors.
First record of Toxodontidae (Mammalia, Notoungulata) from the late Miocene–early Pliocene of the southern central Andes, NW Argentina

Published: February 2017

AbstractA new species of toxodontid notoungulate, Xotodon maimarensis n. sp., is described from the Maimará Formation (late Miocene–early Pliocene), Jujuy Province, northwestern Argentina. This is the first record of a toxodontid from the Eastern Cordillera. The specimen is housed at the Museo de Geología, Mineralogía y Paleontología, Instituto de Geología y Minería de la Universidad Nacional de Jujuy. It consists of an incomplete mandible preserving the right mandibular ramus with part of the dental series, partially preserved symphysis with all the incisors, and a small portion of the left ramus without teeth. The following characters distinguish it as a new taxon: symphysis long and narrow with slight divergence of its lateral borders; strong procumbence of lower incisors and deeply implanted i3; chin angle lower than in X. major and X. cristatus and bulging labial keel limiting strong lateral concavities. Comparative analysis in the context of the recently revised Neogene Toxodontidae indicates that the Maimará specimen shares mandibular features and dental characters with Xotodon and Mixotoxodon, differing from the latter by the more upraised symphysis. The phylogenetic position of Xotodon maimarensis n. sp. supports the taxonomic interpretation of the studied specimen as a new species of Xotodon. This new Toxodontidae increases the knowledge of the diversity and radiation of this group of notoungulates in northwest Argentina.

AbstractThe endoparasitoidMicroplitis prodeniaeRao and Chandry is an important potential augmentative biological control agent for lepidopteran pests of vegetables and tobacco. However, cold storage of pupae is required to ensure that sufficient parasitoids are available when they are needed in the field. In this study, pupae were maintained at 0, 4 or 10°C for 5–50 days after which the adults were evaluated for emergence, pre-emergence period, sex ratio, female longevity, oviposition period, and fecundity. Cold storage did not affect the pre-emergence period or proportion of females; however, there was a significant reduction in emergence, female longevity, oviposition period, and fecundity with increased exposure to cold. The pre-emergence period was approximately 5 days, and approximately 50% of the emergent parasitoids were females. A cold storage regime of 10 days at 10°C had no effect on the parasitoids and adult emergence was greater than 50% even after 20 days at 10°C. There was no carryover of the cold treatment from parental to F1 and F2 generations. Thus,M. prodeniaecan be stockpiled for field release by exposing the pupae to a cold regime and subsequently holding them for adult emergence at 28°C.
