The role of bone in glenohumeral stability
Authors: Di Giacomo Giovanni , Piscitelli Luigi , Pugliese Mattia 
Published: December 2018

Shoulder stability depends on several factors, either anatomical or functional. Anatomical factors can be further subclassified under soft tissue (shoulder capsule, glenoid rim, glenohumeral ligaments etc) and bony structures (glenoid cavity and humeral head). Normal glenohumeral stability is maintained through factors mostly pertaining to the scapular side: glenoid version, depth and inclination, along with scapular dynamic positioning, can potentially cause decreased stability depending on the direction of said variables in the different planes. No significant factors in normal humeral anatomy seem to play a tangible role in affecting glenohumeral stability. When the glenohumeral joint suffers an episode of acute dislocation, either anterior (more frequent) or posterior, bony lesions often develop on both sides: a compression fracture of the humeral head (or Hill–Sachs lesion) and a bone loss of the glenoid rim. Interaction of such lesions can determine ‘re-engagement’ and recurrence. The concept of ‘glenoid track’ can help quantify an increased risk of recurrence: when the Hill–Sachs lesion engages the anterior glenoid rim, it is defined as ‘off-track’; if it does not, it is an ‘on-track’ lesion. The position of the Hill–Sachs lesion and the percentage of glenoid bone loss are critical factors in determining the likelihood of recurrent instability and in managing treatment. In terms of posterior glenohumeral instability, the ‘gamma angle concept’ can help ascertain which lesions are prone to recurrence based on the sum of specific angles and millimetres of posterior glenoid bone loss, in a similar fashion to what happens in anterior shoulder instability.Cite this article: EFORT Open Rev 2018;3:632-640.

Published: December 2018

This paper addresses the robust formation control of non-holonomic mobile robots with homogeneous system architecture and decentralized control structure. Therefore, it was necessary the mathematical modeling of mobile robots, from which, the Separation-Bearing variant of Leader-Following control strategy was implemented. The stability proof were based on the Lyapunov theory. The sliding mode control (SMC) strategy was used in the controller design to make the control robust to the incidence of uncertainties and disturbances. The Fuzzy Adaptive Formation Control is designed to eliminate the previous bounding knowledge of these uncertainties and disturbances. The proposed control effectiveness is demonstrated by results obtained with simulations in Matlab/Simulink. The pure kinematic and kinematic with disturbances is also analyzed. The results shows the controllers effectiveness to formation of multi-robots systems to the eight-shaped trajectory.

AbstractBackgroundFlow cytometric enumeration of lymphocyte subsets in peripheral blood can provide important information about immune status. Commutable reference materials (RM) are crucial for maintaining accurate and comparable measurement results over time and space. Commutability assessment of RMs for lymphocyte subsets enumeration has not been reported elsewhere.MethodsLymphocyte subsets were measured in triplicate on 56 patient samples and eight RMs using two measuring systems commonly used in laboratories (FACS Canto II and Cytomics FC500). The first step was to determine the suitability of RMs and comparability of different systems with patient samples. After the requirements of suitability and comparability were met, the second step was to assess commutability following regression approach and difference in bias approach.ResultsTwo RMs were not measurable on FC500 system for CD3-CD16/56+ and CD3-CD19+ percentages. The results of comparability showed no significant difference in the two systems. Eight RMs for CD3+CD4+ cell count, six RMs for CD3+ and CD3+CD8+ percentages, five RMs for CD3-CD16/56+ percentage, and three RMs for CD3-CD19+ percentage were commutable using the two approaches. For CD3+, CD3+CD8+ and CD3-CD19+ percentages, the results of regression approach showed that one RM was non-commutable for each parameter, while the other approach showed that the RM was commutable.ConclusionsThe suitability of RM and comparability of different measuring systems are prerequisites for assessing commutability. This study indicated that different approaches led to different results. The difference in bias approach is recommended for criteria relating to medical requirements and performance characteristics of measuring systems in use.

Authors: Urrechaga Eloísa , Bóveda Oihane , Aguirre Urko 
Published: December 2018

Abstract

Background
The cell population data (CPD) parameters reported by XN analyzers (Sysmex Corporation, Kobe, Japan) reflect the size and internal structure of leukocytes. We explored whether CPD values could contribute to recognize those patients with fever at risk to develop sepsis. A profile of sepsis was developed combining CPD parameters and other markers.

Methods
We recruited 295 patients at the onset of fever, with infection confirmed by positive cultures. We studied the diagnostic performance of the CPD parameters in the differential diagnosis of sepsis vs. non-systemic bacterial infection using receiver operating characteristic (ROC) curve analysis. Additionally, the K-means unsupervised clustering method was applied. Once the clusters had been defined, the relationship between them and the CPD parameter values was assessed with the non-parametric Wilcoxon test. Lastly, the relationship between the clusters obtained and the categorical variables was examined with the χ2-test (or Fisher’s exact test).

Results
ROC analysis demonstrated that NE-FSL, NE-WY, NE-WZ and MO-WZ had areas under the curve (AUCs) >0.700 for predicting sepsis. Using the K-means clustering algorithm, 80 patients (66.67%) were assigned to Cluster 1 and the others to Cluster 2. Out of 80 of patients in Cluster 1, 45 (56.25%) presented a PCT value ≥2 ng/mL, whereas almost 80% of Cluster 2 patients had a PCT <2 ng/mL. Cluster 1 was characterized by high NE-SFL, NE-WY, MO-X, MO-WX and MO-Z values (p<0.05).

Conclusions
CPD related to monocyte complexity and neutrophil activation were found to be significant, with high values suggesting sepsis.
What Drives Price Dispersion in the European E-commerce Industry?
Authors: Gyódi Kristóf , Sobolewski Maciej , Ziembiński Michał 
Published: December 2018

Abstract
An important aspect of economic integration of the European Union is price convergence on digital single market. In this study, we propose a novel way to measure price dispersion in the e-commerce industry, using a custom made web-scraping tool. We target all the major price comparisons sites in the 26 EU member states, which enables us to collect price signals from thousands of retail shops operating on-line. We analyse pricing data of 182 branded products sold on-line across the EU, representing the most popular categories: fashion, consumer electronics, gaming and software, and cosmetics. We find considerable dispersion of both pre and post-vat on-line prices ranging from 20% to 40%, depending on the product category. The observed on-line price dispersion is driven by both cost factors and the level of per capita income, which is consistent with the view that producers or large distributors might engage in strategic price discrimination induced by income heterogeneity.
At first look, our results point to the unexplored potential for cross-border trade, which could be released by policy interventions with regards to delivery, payment or law harmonization. However, under strategic price discrimination, reduced costs of arbitrage for consumers might induce discriminating firms to lower the magnitude of price dispersion between high and low income countries, bringing adverse welfare changes of a priori unknown net effect.

Published: December 2018

Abstract

Background
Arthrogryposis multiplex congenita is the presence of multiple congenital contractures of two or more body parts. Congenital cytomegalovirus (CMV) infection is a rare etiology of arthrogryposis.

Case presentation
We report a case of intrauterine fetal akinesia and arthrogryposis multiplex congenita delivered at term with subsequent neonatal demise. Placental pathology and autopsy revealed congenital CMV infection.

Conclusions
Evaluation for potential CMV infection is an important part of the arthrogryposis evaluation which is often missed due to lack of maternal infectious symptoms during pregnancy.
Relationships between step and cumulative PMI and E-factors: implications on estimating material efficiency with respect to charting synthesis optimization strategies
Authors: Andraos John 
Published: December 2018

Abstract
This report describes mathematical relationships between step and cumulative process mass intensities (PMIs) for synthesis plans, and analogous parameters applied to E-factors. It is shown that both step E-factors and step PMIs are not additive for synthesis plans. It is also shown that a recursive calculation of cumulative PMIs from step PMIs is a rapid method of determining overall PMIs for synthesis plans, though cumulative PMIs are not sufficiently informative as step PMIs or step E-factors to identify bottlenecks in synthesis plans. Illustrations on the use of these metrics to track the material efficiency of published synthesis plans for the pharmaceutical, apixaban, are given as a template example. Advantages and disadvantages of each metric are discussed. A general algorithm to select the most promising candidate synthesis plans considered at the design stage for a given molecular target that most likely satisfy “green” material efficiency criteria is also presented.

Published: December 2018

SUMMARY
We investigated possibilities for the formation of reproductive structures of important sunflower pathogens, Phomopsis helianthi and Phoma macdonaldii, on the husk and kernels of naturally infected and inoculated seeds.
Pycnidia were typically formed at the wider part of the husk in all sunflower lines and hybrids infected by P.helianthi and/or P.macdonaldii, partly immersed in the epidermis. The pycnidia of P.macdonaldii were larger than the pycnidia of P.helianthi.
The kernels infected by P.helianthi showed slight structural changes in comparison with the non-infected achenes. An exception were the seeds of a line which, on infection by P.helianthi, showed a complete disintegration of the central part of the cotyledon while numerous pycnidia formed in the outer layers of the parenchyma. Seeds of lines infected by P.macdonaldii were considerably damaged. The cotyledonary tissue was disintegrated and pycnidia arranged in rows formed in the outer layers of the parenchyma.

Abstract

Background
Based on our previous ethnobotanical survey, the non-investigated Saharan plant Anabasis aretioides Coss. & Moq., growing in the region of Errachidia, was selected for pharmacological investigation. In Moroccan traditional medicine, A. aretioides is being used for diabetes treatment. Thus, the current work aims at evaluating the antidiabetic, antioxidant, and antibacterial activities of the plant in relation to the digestive tract.

Methods
The different parts of the plant (aerial parts, roots, seeds) were extracted with methanol (MeOH) and screened in enzymatic assays for their inhibitory potential against α-amylase and α-glucosidase, as well as antioxidant and antibacterial activities. Furthermore, the phenolic compounds were analyzed using HPLC-DAD-QTOF-MS.

Results
The MeOH extracts of A. aretioides aerial parts, roots, and seeds, respectively, inhibited α-amylase (IC50 of 3148.07 μg/mL, 2440.20 μg/mL, 3395.71 μg/mL) and α-glucosidase (IC50 of 2940.59 μg/mL, 3521.81 μg/mL, 3393.83 μg/mL). Moreover, compared to aerial parts and seeds, the plant roots exhibited higher antioxidant capacity and a potent reducing power. In resazurin microplate assay, the plant parts displayed a minimal inhibitory concentration (MIC) ranging from 7.81 mg/mL to 31.25 mg/mL. Chemical analysis revealed 25 phenolic compounds, with chlorogenic acid as the main phenolic compound in the aerial parts, hesperidin in roots, and quercitrin in seeds.

Conclusion

Anabasis aretioides cited for treatment of diabetes shows promising antioxidant and antibacterial properties, as well as an ability to inhibit digestive enzyme, including α-amylase and α-glucosidase. Thus, our results explain in part the traditional use of this Saharan medicine and open doors for further in vivo mechanistic and functional studies.
Iterated Local Search for Time-extended Multi-robot Task Allocation with Spatio-temporal and Capacity Constraints
Authors: Mitiche Hakim , Boughaci Dalila , Gini Maria 
Published: December 2018

Abstract
We propose a method for task allocation to multiple physical agents that works when tasks have temporal and spatial constraints and agents have different capacities. Assuming that the problem is over-constrained, we need to find allocations that maximize the number of tasks that can be done without violating any of the constraints. The contribution of this work is the study of a new multi-robot task allocation problem and the design and the experimental evaluation of our approach, an iterated local search that is suitable for time critical applications. We created test instances on which we experimentally show that our approach outperforms a state-of-the-art approach to a related problem. Our approach improves the baseline’s score on average by 2.35% and up to 10.53%, while responding in times shorter than the baseline’s, on average, 1.6 s and up to 5.5 s shorter. Furthermore, our approach is robust to run replication and is not very sensitive to parameters tuning.
A Comparative Analysis of Dual-Order Bidirectional Pumping Schemes in Optical Fiber Raman Amplification
Authors: Singh Kulwinder , Patterh Manjeet Singh , Bhamrah Manjit Singh 
Published: December 2018

Abstract
In this paper, dual-order bidirectional pumping schemes of distributed fiber Raman amplifier are compared with standard first-order pumping in wavelength division multiplexed optical transmission systems. The novel comparison analysis is carried out in terms of Optical signal-to-noise ratio and Q-factor, on-off gain and noise figure by varying optical input power and fiber lengths. The results indicate that dual-order schemes present 0.02 dB higher OSNR and 5 dB higher Q-factor in comparison to first-order pumping when input optical power is varied from −4 to 5 dBm. Similarly, there is 4 dB higher on-off gain with dual order comparatively to first order when fiber length varied from 10 to 100 km. However, there is degradation in noise figure and Q-factor due to DRBS noise with dual-order pumping when fiber length from 10 to 100 km. Further, the signal power evolutions along fiber length show that there is 5 dBm improvement for 100 km fiber. The novelty of the work is that comparative analysis exhibits improvement in OSNR, on-off gain and Q-factor using dual-order bidirectional pumping.

A Novel Multicast Scheme with Grooming for Quality of Service (QoS) Provision and Resource Optimization over Optical Label Switching (OLS) Networks
Authors: Khlifi Yassine , Alotaibi Majid , Othmani Mohamed 
Published: December 2018

Abstract
Optical label switching is proposed for providing fast all-optical switching, covering all granularities transfer and assuring quality of service support. However, the important issue is improving optical resource and providing a steadiness between satisfying traffic demands and reducing resource utilization. This paper proposes a novel multicast approach which enables grooming using an upgraded core node architecture that switches suitably unicast and multicast connections. The proposed node architecture manages appropriately all optical resource including a fiber delay line and wavelength bandwidth, as well as traffic requirements. A new label framework is introduced to assure the required information exchange for handling suitably real-time traffic constraints and optical resource status. Moreover, innovative signaling and switching schemes are introduced to perform suitably lightpath and traffic constraints supervision. Theoretical model and simulation experiments are conducted for validating the proposed scheme and evaluating its performances and effectiveness. Finally, the proposal guarantees traffic requirements and reduces resource usage while improving resource availability.
