Model predictive control based on chaos particle swarm optimization for nonlinear processes with constraints
Authors: Taeib Adel , Soltani Moêz , Chaari Abdelkader 
Published: November 2014

Purpose
– The purpose of this paper is to propose a new type of predictive fuzzy controller. The desired nonlinear system behavior is described by a set of Takagi-Sugeno (T-S) model. However, due to the complexity of the real processes, obtaining a high quality control with a short settle time, a periodical step response and zero steady-state error is often a difficult task. Indeed, conventional model predictive control (MPC) attempts to minimize a quadratic cost over an extended control horizon. Then, the MPC is insufficient to adapt to changes in system dynamics which have characteristics of complex constraints. In addition, it is shown that the clustering algorithm is sensitive to random initialization and may affect the quality of obtaining predictive fuzzy controller. In order to overcome these problems, chaos particle swarm optimization (CPSO) is used to perform model predictive controller for nonlinear process with constraints. The practicality and effectiveness of the identification and control scheme is demonstrated by simulation results involving simulations of a continuous stirred-tank reactor.

Design/methodology/approach
– A new type of predictive fuzzy controller. The proposed algorithm based on CPSO is used to perform model predictive controller for nonlinear process with constraints.

Findings
– The results obtained using this the approach were comparable with other modeling approaches reported in the literature. The proposed control scheme has been show favorable results either in the absence or in the presence of disturbance compared with the other techniques. It confirms the usefulness and robustness of the proposed controller.

Originality/value
– This paper presents an intelligent model predictive controller MPC based on CPSO (MPC-CPSO) for T-S fuzzy modeling with constraints.

Education as a subversive activity: a proposal
Authors: Richards Larry 
Published: November 2014

Purpose
– The purpose of this paper is to present a case for a change of educational system, rather than a change in the current system. A rudimentary framework for an alternative educational system is proposed.

Design/methodology/approach
– Cybernetic and educational literature supports an alternative approach to education. Design principles are identified for an alternative system.

Findings
– For the desirable integration of curricular and pedagogical principles to be realized in an educational system, a non-hierarchical organizational structure is required. The icosahedral structure that embeds Stafford Beer's syntegration process provides such a default structure. Such a structure would be subversive in the current society.

Social implications
– The implementation of the proposed system of schools could transform society by offering an alternative way of thinking about the structure of organizations like schools, as well as political and economic organizations. In so doing, fully participative democratic processes could be realized and sustained.

Originality/value
– The use of the icosahedral structure as a framework for creating a system of schools world-wide is new and has value for anyone contemplating alternative educational systems.
A metaheuristic algorithm for project selection and scheduling with due windows and limited inventory capacity
Authors: Garcia Christopher 
Published: November 2014

Purpose
– The purpose of this paper is to provide an effective solution for a complex planning problem encountered in heavy industry. The problem entails selecting a set of projects to produce from a larger set of solicited projects and simultaneously scheduling their production to maximize profit. Each project has a due window inside of which, if accepted, it must be shipped. Additionally, there is a limited inventory buffer where lots produced early are stored. Because scheduling affects which projects may be selected and vice-versa, this is a particularly difficult combinatorial optimization problem.

Design/methodology/approach
– The authors develop an algorithm based on the Metaheuristic for Randomized Priority Search (Meta-RaPS) as well as a greedy heuristic and an integer programming (IP) model. The authors then perform computational experiments on a large set of benchmark problems over a wide range of characteristics to compare the performance of each method in terms of solution quality and time required.

Findings
– The paper shows that this problem is very difficult to solve using IP, with even small instances unable to be solved optimally. The paper then shows that both proposed algorithms will in seconds often outperform IP by a large margin. Meta-RaPS is particularly robust, consistently producing the best or very near-best solutions.

Practical implications
– The Meta-RaPS algorithm developed enables companies facing this problem to achieve higher profits through improved decision making. Moreover, this algorithm is relatively easy to implement.

Originality/value
– This research provides an effective solution for a difficult combinatorial optimization problem encountered in heavy industry which has not been previously addressed in the literature.
Risks to a mountain summit ecosystem with endemic biota in southwestern Australia
Authors: Barrett Sarah , Yates Colin J. 
Published: November 2014

Abstract Throughout the world, mountains provide unique environments with attendant endemic species. In the otherwise subdued landscapes of the floristically diverse Southwest Western Australian Floristic Region, the Stirling Range provides the region's only distinctly montane environments. On the highest peaks of the Range the characteristic heathland (Kwongan) of the region becomes a dense shrub thicket with many endemic species and is known as the Eastern Stirling Range Montane Heath and Thicket. We assessed the conservation status of the Montane Heath and Thicket using the IUCN Red list criteria for ecosystems. We found the ecosystem to be Critically Endangered based on its naturally limited geographic extent and area of occupancy in combination with the impacts of the plant pathogen Phytophthora cinnamomi. Historical sources and long‐term monitoring were critical to our assessment of this ecosystem highlighting their importance in detecting and understanding likely causes of change. The ecosystem is predicted to decline further in the absence of intensive management due to current threatening processes as well as the potential future impacts of climate change. The Montane Heath and Thicket, while substantially modified still retains areas with highly significant conservation values and these pose many challenges for management. Continued management of P. cinnamomi through phosphite application and management of fire return intervals will be critical to conserve the remaining areas of the thicket where sensitive plant species occur together with an ex situ conservation program including ongoing seed collection and translocation for the most threatened species.

SummaryThe aim of this study was to determine the histomorphological changes that occurred in response to two treatments for oestrus synchronization in three different regions of the gilt's uterine tubes epithelium: the ampulla (AMP), ampulla–isthmic junction (AIJ) and isthmus (IST). Nine prepuberal gilts were divided into three groups (n = 3): (1) eCG 400 IU and hCG 200 IU (eCG/hCG), (2) progesterone agonist (P4) and (3) control group. The number of secretory cells (stained with periodic acid–Schiff reaction or PAS‐positive cells) decreased in the AMP in the P4 treated group when compared to the control group, whereas, no difference was observed in the number of PAS‐negative cells in the AMP of the three groups. A significant decrease in the number of PAS‐positive cells was observed in the AIJ and IST of the P4 treated group when compared to the eCG/hCG and control groups. An increase in the number of PAS‐negative cells was observed in the AIJ and IST in the P4 treated group. The epithelium height in the AMP and AIJ was increased in the eCG/hCG group when compared to the control and P4 groups. In this last group, we observed a reduced height compared with the other two groups for the AIJ. In the IST, there were no significant changes in the epithelium height of the control or the other two groups (eCG/hCG and P4). The epithelial cells of the P4 treated group had the least amount of cytoplasmic granules and the lowest intensity of PAS staining in the AMP, AIJ and IST. Animals treated with eCG/hCG showed an intermediate number of cytoplasmic granules and intensity in all regions evaluated. These data show that P4 treatment for synchronization induces a significant (P < 0.001) decrease of PAS‐positive cells and staining intensity of cytoplasmic granules in the different regions studied and an increased number of PAS‐negative cells in the AIJ and IST epithelium. Moreover, eCG/hCG treatment increased the height of the epithelium in the AMP and AIJ, while in this last region, the P4 treatment decreased the epithelium height. These results show that synchronization treatments with P4 and in a smaller proportion with eCG/hCG can modify the amount of PAS‐positive and PAS‐negative cells, and the epithelium height. This has influence in the secretory activity of the epithelium and possibly alters the fluid microenvironment of the gilt's uterine tube. The biological impact of regional variations in the epithelial cells of the gilt′s uterine tube needs further investigation to understand the implications that the reproductive processes can have in the uterine tube.
Cranial nerve injuries with supraglottic airway devices: a systematic review of published case reports and series
Authors: Thiruvenkatarajan V. , Van Wijk R. M. , Rajbhoj A. 
Published: November 2014

SummaryCranial nerve injuries are unusual complications of supraglottic airway use. Branches of the trigeminal, glossopharyngeal, vagus and the hypoglossal nerve may all be injured. We performed a systematic review of published case reports and case series of cranial nerve injury from the use of supraglottic airway devices. Lingual nerve injury was the most commonly reported (22 patients), followed by recurrent laryngeal (17 patients), hypoglossal (11 patients), glossopharyngeal (three patients), inferior alveolar (two patients) and infra‐orbital (one patient). Injury is generally thought to result from pressure neuropraxia. Contributing factors may include: an inappropriate size or misplacement of the device; patient position; overinflation of the device cuff; and poor technique. Injuries other than to the recurrent laryngeal nerve are usually mild and self‐limiting. Understanding the diverse presentation of cranial nerve injuries helps to distinguish them from other complications and assists in their management.
A randomised, single‐blind technical study comparing the ultrasonic visibility of smooth‐surfaced and textured needles in a soft embalmed cadaver model

Published: November 2014

SummaryVisibility of the needle tip and shaft is important during ultrasound‐guided regional anaesthesia in order to prevent nerve trauma. Tip and shaft visibility is reduced when needles are inserted in‐plane at wide angles and out‐of‐plane at narrow angles to the ultrasound probe. Although textured needles are more reflective than smooth needles, we hypothesised that poor visibility of the tip and shaft still remained using the above angle‐probe combinations. In a single‐blind study, we compared the visibility of a textured Tuohy needle, a textured single‐shot needle and a conventional smooth‐surfaced Tuohy needle when inserted into the biceps and deltoid muscles of a soft embalmed cadaver. One hundred and forty‐four needles were block‐randomised to in‐plane and out‐of‐plane insertions at 30°, 45°, 60° and 75° to the ultrasound beam. Two blinded raters assessed needle tip visibility on video recordings of the insertions using a binary scale (0 = not visible, 1 = visible) and shaft visibility using a 5‐point Likert scale. The median (IQR [range]) proportions of visible needle tips were 83% (67–83 [50–100]%) for the textured Tuohy, 75% (67–83 [33–83]%) for the textured single‐shot needle and 33% (33–46 [0–50]%) for the smooth‐surfaced Tuohy (p = 0.0007). Median (IQR [range]) needle shaft visibility was rated as 4.0 (3.5–4.7 [3.0–4.9]) for the textured Tuohy, 4.0 (3.8–4.5 [2.7–4.9]) for the textured single‐shot needle and 3.0 (2.4–3.3 [2.3–3.5]) for the smooth‐surfaced Tuohy (p = 0.015). Nevertheless, visibility was reduced at wide angles in‐plane and narrow angles out‐of‐plane both for needle tips (p = 0.004) and shafts (p = 0.005).

SummarySjögren's syndrome (SS) is an autoimmune inflammatory disease that primarily affects the lacrimal and salivary glands causing dry eyes and mouth. Antibodies to Ro60 are observed frequently in patients with SS; however, the role of these antibodies in SS initiation and progression remains unclear. The sequence Ro60 273–289 (Ro274) is a known B cell epitope of Ro60 and antibodies to this epitope have been observed in a subset of SS patients and in animals immunized with Ro60 protein. Animals immunized with Ro274 linear peptide develop a Sjögren's-like illness. We hypothesized that passive transfer of anti-Ro274-specific immunoglobulin (Ig)G would induce a Sjögren's-like phenotype. To evaluate this hypothesis, we adoptively transferred affinity-purified Ro274 antibodies into naive BALB/c animals, then evaluated salivary gland histology, function and IgG localization 4 days post-transfer. At this time-point, there was no demonstrable mononuclear cell infiltration and salivary glands were histologically normal, but we observed a functional deficit in stimulated salivary flow of animals receiving Ro274 antibodies compared to animals receiving control IgG. Cellular fractionation and enzyme-linked immunosorbent assay revealed Ro274-specific antibodies in the nucleus and cytoplasmic fractions of isolated parotid salivary gland cells that was confirmed by immunohistochemistry. These data support the hypothesis that antibodies to Ro274 deposit in salivary glands can enter intact salivary gland cells and are involved in the dysregulation of salivary flow in SS.

Published: November 2014

Summary
Our objective was to evaluate the contribution of monitoring B cell subset depletion after rituximab in patients with rheumatoid arthritis (RA) in order to guide reintroduction to forestall relapse. This prospective, monocentre study included all RA patients receiving two 1-g rituximab infusions at a 15-day interval. The patients were followed clinically and biologically every 2 months until rituximab reintroduction. The physician was blinded to lymphocyte-typing results to diagnose relapse and, hence, retreatment. Among the 39 patients included between March 2010 and December 2011 and followed until April 2013, seven received two rituximab cycles, yielding a total of 46 cycles for analysis. After the two rituximab cycles, the total number of CD19+ B cells decreased significantly (0·155 versus 0·0002 G/l, P &lt; 0·0001), with complete depletions in all patients of CD19+ CD38++ CD24++ (transitional) (P &lt; 0·0001) and CD19+ CD27+ (memory) B lymphocytes. A significant majority of patients relapsed within the 4 months following repopulation of total B (P = 0·036), B transitional (P = 0·007) and B memory (P = 0·01) lymphocytes. CD19+ B lymphocyte repopulation preceded clinical RA relapse and enabled its prediction 4 months in advance. Hence, monitoring of CD19+ B lymphocytes could serve as a tool to predict those relapses.
Example‐Based Retargeting of Human Motion to Arbitrary Mesh Models

Published: November 2014

AbstractWe present a novel method for retargeting human motion to arbitrary 3D mesh models with as little user interaction as possible. Traditional motion‐retargeting systems try to preserve the original motion, while satisfying several motion constraints. Our method uses a few pose‐to‐pose examples provided by the user to extract the desired semantics behind the retargeting process while not limiting the transfer to being only literal. Thus, mesh models with different structures and/or motion semantics from humanoid skeletons become possible targets. Also considering the fact that most publicly available mesh models lack additional structure (e.g. skeleton), our method dispenses with the need for such a structure by means of a built‐in surface‐based deformation system. As deformation for animation purposes may require non‐rigid behaviour, we augment existing rigid deformation approaches to provide volume‐preserving and squash‐and‐stretch deformations. We demonstrate our approach on well‐known mesh models along with several publicly available motion‐capture sequences.

AbstractPurposeThis prospective cohort study evaluates the 10‐year survival and incidence of peri‐implant disease at implant and patient level of sandblasted, large grid, and acid‐etched titanium dental implants (Straumann, soft tissue level,SLAsurface) in fully and partially edentulous patients.Material and methodsPatients who had dental implant surgery in the period between November 1997 and June 2001, with a follow‐up of at least 10 years, were investigated for clinical and radiological examination. Among the 506 inserted dental implants in 250 patients, 10‐year data regarding the outcome of implants were available for 374 dental implants in 177 patients. In the current study, peri‐implantitis was defined as advanced bone loss (≧1.5 mm. postloading) in combination with bleeding on probing.ResultsAt 10‐year follow‐up, only one implant was lost (0.3%) 2 months after implant surgery due to insufficient osseointegration. The average bone loss at 10 year postloading was 0.52 mm. Advanced bone loss at 10‐year follow‐up was present in 35 dental implants (9.8%). Seven percent of the observed dental implants showed bleeding on probing in combination with advanced bone loss and 4.2% when setting the threshold for advanced bone loss at 2.0 mm. Advanced bone loss without bleeding on probing was present in 2.8% of all implants.ConclusionIn this prospective study, the 10‐year survival rate at implant and patient level was 99.7% and 99.4%, respectively. Peri‐implantitis was present in 7% of the observed dental implants according to the above‐mentioned definition of peri‐implantitis. This study shows thatSLAimplants offer predictable long‐term results as support in the treatment of fully and partially edentulous patients.

Published: November 2014

SummaryAimSCUBA diving frequently involves repetitive exposures. The goal of this study was to see how exercise impacts microparticles (MPs), endothelial function and venous gas emboli (VGE) throughout multiple dives.MethodsSixteen divers in two groups (G1 and G2) each completed six dives, three preceded by exercise (EX) and three as controls (CON). Blood for MP analysis was collected before and after each dive. VGE were monitored via transthoracic echocardiography 30, 60 and 90 min after surfacing. Exercise before diving consisted of 60‐min running including eight, 3‐min intervals at 90% VO2max.ResultsExercise did not have a significant impact on VGE. There was no significant difference in MP counts between EX and CON. Both groups experienced a significant decrease in MP counts in the last three dives compared to the first three (G1 P = 0·0008, G2 P = 0001). Other indices of neutrophil/platelet interaction (dual‐positive CD63/41 and CD62/41) show a significant increase (P = 0·004 and 0·0001) in G2.ConclusionBoth groups experienced a significant decrease in MPs at all measurements in the second series of dives compared to the first, regardless of the placement of exercise. Whether this is related to an effect of suppression of MPs or exercise timing is not clear.
Hydrophilic polymer microemboli in a patient with a chronic cutaneous ulcer: a case report
Authors: Hamidi Sepehr , Stevens Ryan , DeClerck Brittney , Kim Gene H. 
Published: November 2014

AbstractHydrophilic polymer coatings were designed to reduce friction between the catheter and vessel wall and facilitate intravascular manipulations during catheterization and placement of drug‐eluting stents. One newly reported complication of such hydrophilic coatings is the fragmentation and embolization of the polymer, which can lead to ischemia and infarct by blocking the small vasculature. In this report, we present a patient with a non‐healing ulcer on the leg. Biopsy from the ulcer revealed the presence of hydrophilic polymer emboli within the dermal vessels. This is one of the few reports of such a complication involving the skin. Our objective is to emphasize the histopathologic features of this uncommon iatrogenic phenomenon.
