Decentralized adaptive control of nonlinear large‐scale pure‐feedback interconnected systems with time‐varying delays
Authors: He Chao , Li Junmin , Zhang Lin 
Published: December 2013

SUMMARYIn this paper, an adaptive decentralized neural control problem is addressed for a class of pure‐feedback interconnected system with unknown time‐varying delays in outputs interconnections. By taking advantage of implicit function theorem and the mean‐value theorem, the difficulty from the pure‐feedback form is overcome. Under a wild assumption that the nonlinear interconnections are assumed to be bounded by unknown nonlinear functions with outputs, the difficulties from unknown interconnections are dealt with, by introducing continuous packaged functions and hyperbolic tangent functions, and the time‐varying delays in interconnections are compensated by Lyapunov–Krasovskii functional. Radial basis function neural network is used to approximate the unknown nonlinearities. Dynamic surface control is successfully extended to eliminate ‘the explosion of complexity’ problem in backstepping procedure. To reduce the computational burden, minimal learning parameters technique is successfully incorporated into this novel control design. A delay‐independent decentralized control scheme is proposed. With the adaptive neural decentralized control, only one estimated parameter need to be updated online for each subsystem. Therefore, the controller is more simplified than the existing results. Also, semiglobal uniform ultimate boundedness of all of the signals in the closed‐loop system is guaranteed. Finally, simulation studies are given to demonstrate the effectiveness of the proposed design scheme. Copyright © 2013 John Wiley & Sons, Ltd.

Published: December 2013

AbstractThis work deals with the development of a new family of planar chiral phosphoric acids based on a ferrocenophane/paracyclophane scaffold. The synthetic approach has been improved by taking advantage of a chiral phosphorylating agent to access enantiomerically enriched acids via diastereomers separation. These phosphoric acids have been used as catalysts for the enantioselective H‐transfer reduction of α‐substituted quinolines with Hantzsch esters. Optimization of both the catalyst and the Hantzsch reductant allowed ee values in the range 82–92% to be attained starting from α‐arylquinolines.magnified image
Hypoglycemia in Kabuki syndrome
Authors: Subbarayan Anbezhil , Hussain Khalid 
Published: December 2013

AbstractKabuki syndrome (KS) is a congenital malformation disorder with a spectrum of clinical manifestations involving different organs. Until the identification of MLL2 gene mutation in 2010, the diagnosis was made only clinically by the characteristic facial features with other common and uncommon features. Hypoglycemia, although an uncommon feature in KS, is very important to be recognized, as early diagnosis and appropriate management will reduce further long‐term neurologic morbidity in these patients. We report on four patients with KS presenting with persistent hypoglycemia. Hyperinsulinemic hypoglycemia was the cause of hypoglycemia in two out of four patients and one patient had growth hormone deficiency. The mechanism of the hypoglycemia in one patient is still unclear. Three out of these four patients were found to have mutation in the MLL2 gene. Our observations suggest that patients with KS may have hypoglycemia due to different mechanisms and that MLL2 gene may have a role in glucose physiology. © 2013 Wiley Periodicals, Inc.

AbstractThe identification of causes underlying intellectual disability (ID) is one of the most demanding challenges for clinical Geneticists and Researchers. Despite molecular diagnostics improvements, the vast majority of patients still remain without genetic diagnosis. Here, we report the results obtained using Whole Exome and Target Sequencing on nine patients affected by isolated ID without pathological copy number variations, which were accurately selected from an initial cohort of 236 patients. Three patterns of inheritance were used to search for: (1) de novo, (2) X‐linked, and (3) autosomal recessive variants. In three of the nine proband–parent trios analyzed, we identified and validated two de novo and one X‐linked potentially causative mutations located in three ID‐related genes. We proposed three genes as ID candidate, carrying one de novo and three X‐linked mutations. Overall, this systematic proband–parent trio approach using next generation sequencing could explain a consistent percentage of patients with isolated ID, thus increasing our knowledge on the molecular bases of this disease and opening new perspectives for a better diagnosis, counseling, and treatment. © 2013 Wiley Periodicals, Inc.
Multiple café au lait spots in familial patients with MAP2K2 mutation

Published: December 2013

AbstractRecent advances in genetic diagnostic technologies have made the classic disease nosology highly complicated. This situation is exemplified by rasopathies, among which neurofibromatosis type 1 and Noonan syndrome represent prototypic entities. The former condition is characterized by multiple café au lait spots and neurofibromas, while the latter is characterized by distinct facial features, webbed neck, congenital heart disease, and a short stature. On rare occasions, the features of both neurofibromatosis and Noonan syndrome co‐exist within an individual; such patients are diagnosed as having neurofibromatosis–Noonan syndrome. Here, we report familial patients with multiple café au lait spots and Noonan syndrome‐like facial features. A mutation analysis unexpectedly revealed a mutation in MAP2K2 in both the propositus and his mother. The propositus fulfilled the diagnostic criteria for neurofibromatosis type 1, but his mother did not. Their phenotype was not consistent with that of cardio‐facio‐cutaneous syndrome, which is classically known to be associated with MAP2K2 mutations. The mother of the propositus had cervical cancer at the age of 23 years, consistent with the oncogenic tendency associated with rasopathies. The phenotypic combination of multiple café au lait spots and Noonan syndrome‐like facial features suggested a diagnosis of neurofibromatosis–Noonan syndrome. Whether this condition represents a discrete disease entity or a variable expression of neurofibromatosis type 1 has long been debated. The present observation suggests that some perturbation in the RAS/MAPK signaling cascade results in multiple café au lait spots, a key diagnostic phenotype of rasopathies, although the exact mechanism remains to be elucidated. © 2013 Wiley Periodicals, Inc.
Classic phenotype of Coffin–lowry syndrome in a female with stimulus‐induced drop episodes and a genotype with preserved N‐terminal kinase domain
Authors: Rojnueangnit Kitiwan , Jones Julie R. , Basehore Monica J. , Robin Nathaniel H. 
Published: December 2013

AbstractAn adolescent female presented with intellectual disability, stimulus‐induced drop episodes (SIDEs), facial characteristics that include wide set eyes, short nose with wide columella, full and everted lips with wide mouth and progressive skeletal changes: scoliosis, spondylolisthesis and pectus excavatum. These findings were suggestive of Coffin–Lowry syndrome (CLS), and this was confirmed by the identification of a novel mutation in RPS6KA3, a heterozygous one basepair duplication at nucleotide 1570 (c.1570dupA). This mutation occurs within the C‐terminal kinase domain of the protein, and, therefore contradicts the previous report that SIDEs is only associated with premature truncation of the protein in the N‐terminal kinase domain or upstream of this domain. As CLS is X‐linked, it is unusual for a female to have such a classic phenotype. © 2013 Wiley Periodicals, Inc.
Airway malacia in children with achondroplasia
Authors: Dessoffy Kimberly E. , Modaff Peggy , Pauli Richard M. 
Published: December 2013

AbstractThis study was undertaken to assess the frequency of airway malacia in infants and young children with achondroplasia, a population well known to be at risk for a variety of respiratory problems. We also wished to evaluate what, if any, contribution airway malacia makes to the complex respiratory issues that may be present in those with achondroplasia. Retrospective chart review of all infants and young children with achondroplasia who were assessed through the Midwest Regional Bone Dysplasia Clinics from 1985 through 2012 (n = 236) was completed. Records of comprehensive clinical examinations, polysomnographic assessments, and airway visualization were reviewed and abstracted using a data collection form. Analyses were completed comparing the group with and those without evidence for airway malacia. Thirteen of 236 patients (5.5%) were found to have airway malacia. Most of those affected had lower airway involvement (9/13). The presence of airway malacia was correlated with an increased occurrence of obstructive sleep apnea as well as need for oxygen supplementation, airway surgeries and tracheostomy placement. Although estimates of the frequency of airway malacia in the general population are limited, its frequency in children with achondroplasia appears to be much higher than any published general population estimate. The presence of airway malacia appears to confound other breathing abnormalities in this population and results in the need for more invasive airway treatments. © 2013 Wiley Periodicals, Inc.

CaseWe report a patient with life‐threatening lung contusion who was rescued using poly‐2‐methoxyethyl acrylate, a biocompatible polymer surface coating for extracorporeal membrane oxygenation, which enabled reduction of the dose of systemic anticoagulation to prevent circuit thrombosis.OutcomeA 56‐year‐old man was transferred to our hospital due to blunt chest trauma following a 30‐m fall into water. Chest X‐ray and computed tomography showed bilateral lung contusions with bilateral pneumothorax. Although drainage tubes were inserted and ventilation with positive‐airway pressure was applied, PaO2/FiO2 remained <80 mmHg. Extracorporeal membrane oxygenation was started with heparin (5,000 units) to prevent circuit thrombosis on day 1. No significant bleeding complications or clot formation in the extracorporeal circuit were observed, with stable activated clotting time of 100–160 s without further anticoagulants.ConclusionOur case showed that poly‐2‐methoxyethyl acrylate‐coated extracorporeal membrane oxygenation can be safely applied to patients with lung contusion associated with chest trauma.

AbstractThe scarcity and expense of access to L‐sugars and other rare sugars have prevented the exploitation of their biological potential; for example D‐psicose, only recently available, has been recognized as an important new food. Here we give the definitive and cheap synthesis of 99.4% pure L‐glucose from D‐glucose which requires purification of neither intermediates nor final product other than extraction into and removal of solvents; a simple crystallization will raise the purity to >99.8%.

Published: December 2013

ABSTRACTIn this article, we detail an effective way to improve electrical, thermal, and gas barrier properties using a simple processing method for polymer composites. Graphene oxide (GO) prepared with graphite using a modified Hummers method was used as a nanofiller for r‐GO/PI composites by in situ polymerization. PI composites with different loadings of GO were prepared by the thermal imidization of polyamic acid (PAA)/GO. This method greatly improved the electrical properties of the r‐GO/PI composites compared with pure PI due to the electrical percolation networks of reduced graphene oxide within the films. The conductivity of r‐GO/PI composites (30:70 w/w) equaled 1.1 × 101 S m−1, roughly 1014 times that of pure PI and the oxygen transmission rate (OTR, 30:70 w/w) was reduced by about 93%. The Young's modulus of the r‐GO/PI composite film containing 30 wt % GO increased to 4.2 GPa, which was an approximate improvement of 282% compared with pure PI film. The corresponding strength and the elongation at break decreased to 70.0 MPa and 2.2%, respectively. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40177.

Published: December 2013

Abstract

Background
Several recent studies have investigated the role of C-reactive protein (CRP) as an early marker of anastomotic leakage following colorectal surgery. The aim of this systematic review and meta-analysis was to evaluate the predictive value of CRP in this setting.

Methods
A systematic literature search was performed using MEDLINE, Embase and PubMed to identify studies evaluating the diagnostic accuracy of postoperative CRP for anastomotic leakage following colorectal surgery. A meta-analysis was carried out using a random-effects model and pooled predictive parameters were determined along with a CRP cut-off value at each postoperative day (POD).

Results
Seven studies, with a total of 2483 patients, were included. The pooled prevalence of leakage was 9·6 per cent and the median day on which leakage was diagnosed ranged from POD 6 to 9. The serum CRP level on POD 3, 4 and 5 had comparable diagnostic accuracy for the development of an anastomotic leak with a pooled area under the curve of 0·81 (95 per cent confidence interval 0·75 to 0·86), 0·80 (0·74 to 0·86) and 0·80 (0·73 to 0·87) respectively. The derived CRP cut-off values were 172 mg/l on POD 3, 124 mg/l on POD 4 and 144 mg/l on POD 5; these corresponded to a negative predictive value of 97 per cent and a negative likelihood ratio of 0·26–0·33. All three time points had a low positive predictive value for leakage, ranging between 21 and 23 per cent.

Conclusion
CRP is a useful negative predictive test for the development of anastomotic leakage following colorectal surgery.
Do Individual Preferences Affect the Environmental Decision‐Making Process in Teams? The Role of Participation
Authors: de la Torre‐Ruiz José M. , Aragón‐Correa J. Alberto , Martín‐Tapia Inmaculada 
Published: December 2013

AbstractLiterature on organizations and the natural environment has focused on the importance of individual managers and leaders. However, this literature has scarcely ever focused on individuals in the team context, even when teams have been considered to be key for a firms’ environmental progress. Although teams’ environmental decisions can be enriched by the different contributions of team members, it is necessary that team members actually participate and contribute their preferences during the decision‐making process. We used an adaptation of the legislative dilemma task with 84 students to contribute to environmental management literature by analyzing members’ participation during the team decision‐making process. The results of this paper show how those members with environmentally proactive preferences have a higher participation during the decision‐making process, and as a consequence they have a greater influence on the team decision.
