Modelling internal logistics systems through ontologies

Industry is facing an era characterised by unpredictable market changes and by a turbulent competitive environment. The key to compete in such a context is to achieve high degrees of responsiveness by means of high flexibility and rapid reconfiguration capabilities. The deployment of modular solutions seems to be part of the answer to face these challenges. Semantic modelling and ontologies may represent the needed knowledge representation to support flexibility and modularity of production systems, when designing a new system or when reconfiguring an existing one. Although numerous ontologies for production systems have been developed in the past years, they mainly focus on discrete manufacturing, while logistics aspects, such as those related to internal logistics and warehousing, have not received the same attention. The paper aims at offering a representation of logistics aspects, reflecting what has become a de-facto standard terminology in industry and among researchers in the field. Such representation is to be used as an extension to the already-existing production systems ontologies that are more focused on manufacturing processes. The paper presents the structure of the hierarchical relations within the examined internal logistics elements, namely Storage and Transporters, structuring them in a series of classes and sub-classes, suggesting also the relationships and the attributes to be considered to complete the modelling. Finally, the paper proposes an industrial example with a miniload system to show how such a modelling of internal logistics elements could be instanced in the real world. © 2017 Elsevier B.V.

E-WOM from e-commerce websites and social media: Which will consumers adopt?

The influence of user generated content on e-commerce websites and social media has been addressed in both practical and theoretical fields. Since most previous studies focus on either electronic word of mouth (eWOM) from e-commerce websites (EC-eWOM) or social media (SM-eWOM), little is known about the adoption process when consumers are presented EC-eWOM and SM-eWOM simultaneously. We focus on this problem by considering their adoption as an interactive process. It clarifies the mechanism of consumer’s adoption for those from the perspective of cognitive cost theory. A conceptual model is proposed about the relationship between the adoptions of the two types of eWOM. The empirical analysis shows that EC-eWOM’s usefulness and credibility positively influence the adoption of EC-eWOM, but negatively influence that of SM-eWOM. EC-eWOM adoption negatively impacts SM-eWOM adoption, and mediates the relationship between usefulness, credibility and SM-eWOM adoption. The moderating effects of consumers’ cognitive level and degree of involvement are also discussed. This paper further explains the adoption of the two types of eWOM based on the cognitive cost theory and enriches the theoretical research about eWOM in the context of social commerce. Implications for practice, as well as suggestions for future research, are also discussed. 2016 Elsevier B.V. All rights reserved.
Accurate network anomaly classification with generalized entropy metrics

The accurate detection and classification of network anomalies based on traffic feature distributions is still a major challenge. Together with volume metrics, traffic feature distributions are the primary source of information of approaches scalable to high-speed and large scale networks. In previous work, we proposed to use the Tsallis entropy based traffic entropy spectrum (TES) to capture changes in specific activity regions, such as the region of heavy-hitters or rare elements. Our preliminary results suggested that the TES does not only provide more details about an anomaly but might also be better suited for detecting them than traditional approaches based on Shannon entropy. We refine the TES and propose a comprehensive anomaly detection and classification system called the entropy telescope. We analyze the importance of different entropy features and refute findings of previous work reporting a supposedly strong correlation between different feature entropies and provide an extensive evaluation of our entropy telescope. Our evaluation with three different detection methods (Kalman filter, PCA, KLE), one classification method (SVM) and a rich set of anomaly models and real backbone traffic demonstrates the superiority of the refined TES approach over TES and the classical Shannon-only approaches. For instance, we found that when switching from Shannon to the refined TES approach, the PCA method detects small to medium sized anomalies up to 20% more accurately. Classification accuracy is improved by up to 19% when switching from Shannon-only to TES and by another 8% when switching from TES to the refined TES approach. To complement our evaluation, we run the entropy telescope on one month of backbone traffic finding that most prevalent anomalies are different types of scanning (69–84%) and reflector DDoS attacks (15–29%). 2011 Elsevier B.V.

Vitamin D Supplementation and the Risk of Colds in Patients with Asthma.

RATIONALE
Restoration of vitamin D sufficiency may reduce asthma exacerbations, events that are often associated with respiratory tract infections and cold symptoms.


OBJECTIVES
To determine whether vitamin D supplementation reduces cold symptom occurrence and severity in adults with mild to moderate asthma and vitamin D insufficiency.


METHODS
Colds were assessed in the AsthmaNet VIDA (Vitamin D Add-on Therapy Enhances Corticosteroid Responsiveness) trial, in which 408 adult patients were randomized to receive placebo or cholecalciferol (100,000 IU load plus 4,000 IU/d) for 28 weeks as add-on therapy. The primary outcome was cold symptom severity, which was assessed using daily scores on the 21-item Wisconsin Upper Respiratory Symptom Survey.


MEASUREMENTS AND MAIN RESULTS
A total of 203 participants experienced at least one cold. Despite achieving 25-hydroxyvitamin D levels of 41.9 ng/ml (95% confidence interval [CI], 40.1-43.7 ng/ml) by 12 weeks, vitamin D supplementation had no effect on the primary outcome: the average peak WURSS-21 scores (62.0 [95% CI, 55.1-68.9; placebo] and 58.7 [95% CI, 52.4-65.0; vitamin D]; P = 0.39). The rate of colds did not differ between groups (rate ratio [RR], 1.2; 95% CI, 0.9-1.5); however, among African Americans, those receiving vitamin D versus placebo had an increased rate of colds (RR, 1.7; 95% CI, 1.1-2.7; P = 0.02). This was also observed in a responder analysis of all subjects achieving vitamin D sufficiency, regardless of treatment assignment (RR, 1.4; 95% CI, 1.1-1.7; P = 0.009).


CONCLUSIONS
Our findings in patients with mild to moderate asthma undergoing an inhaled corticosteroid dose reduction do not support the use of vitamin D supplementation for the purpose of reducing cold severity or frequency.
Is linguistic information relevant for the text legal classification problem?

Text classification is an important task in the legal domain. In fact, most of the legal information is stored as text in a quite unstructured format and it is important to be able to automatically classify these texts into a predefined set of concepts.Support Vector Machines (SVM), a machine learning algorithm, has shown to be a good classifier for text bases [12]. In this paper, SVMs are applied to the classification of European Portuguese legal texts - the Portuguese Attorney General's Office Decisions - and the relevance of linguistic information in this domain, namely lemmatisation and part-of-speech tags, is evaluated.The obtained results show that some linguistic information (namely, lemmatisation and the part-of-speech tags) can be successfully used to improve the classification results and, simultaneously, to decrease the number of features needed by the learning algorithm.

Eddy-Current Displacement Transducer With Extended Linear Range and Automatic Tuning

Design details and measurement results of the eddy-current displacement transducer with extended linear range and automatic tuning are presented. The transducer is based on a resonant impedance inversion method of transfer curve linearization where the displacement probe circuit is kept in resonance by the resonance control loop. The transducer exhibits an extended linear range due to the compensation of displacement probe losses by a negative impedance converter (NIC) at the transducer input. Particular attention is paid to the NIC design and its temperature compensation. The new voltage-controlled NIC circuit is introduced, which can easily be realized with a standard commercial integrated circuit (LM 1496). Details of the transducer's reference generator and the NIC control voltage generator are also presented. The transducer's linear range extends from 0.25 to 3.75 mm (approximately 44% of the 8-mm probe diameter) while maintaining nonlinearity within plusmn2% F.S. This result is, at least, a 75% improvement to the best commercially available eddy-current displacement transducers (a linear range of 80 mil ~2 mm for an 8-mm probe). Further linearization can be achieved by postlinearization of the detected signal.
Probabilistic performance assessment of a roof top wind, solar photo voltaic hybrid energy system

The escalation in electrical energy costs associated with fossil and nuclear fuels, and enhanced public awareness of potential environmental impacts of conventional energy systems has created an increased interest in the development and utilization of alternate sources. Photo voltaic and wind energy sources are being increasingly recognized as cost effective generation sources in small isolated power systems. A realistic cost benefit analysis requires evaluation models that can recognize the highly erratic nature of these energy sources while maintaining the chronology and inter dependence of the random variables inherent in them. This paper reports the probabilistic performance assessment of a wind, solar photo voltaic (SPV) hybrid energy system. A 400 watt wind electric generator (WEG), 840 WP (peak watt power) solar photo voltaic power generator, 6/spl times/75 Amp-Hour (Ah) backup storage batteries, charge controller (CC), 1 KVA inverter (INV), etc were designed, integrated and optimized to predict the behavior of generating system based on available local wind / solar and load data at Vasavi College of Engineering, Hyderabad, India. Storage batteries can be designed for various hours of uninterrupted power supply in the event of wind & SPV energy failures. This model is useful for evaluating the probabilistic reliability evaluation of generating systems and gaining a better insight in the component sizes needed before they are built. The loss of supply and effects of the randomness of the wind and solar radiation's were presented. The wind solar photo voltaic hybrid energy system (WSPVHES) is working satisfactorily. The above system is reliable and economical for remote applications.
Diagnostic Performance of (68)Ga-DOTATATE PET/CT, (18)F-FDG PET/CT and (131)I-MIBG Scintigraphy in Mapping Metastatic Pheochromocytoma and Paraganglioma.

PURPOSE
To evaluate the diagnostic performance of (68)Ga-DOTATATE (18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT), (18)F-FDG PET/CT and (131)I-MIBG scintigraphy in the mapping of metastatic pheochromocytoma and paraganglioma.


MATERIALS AND METHODS
Seventeen patients (male = 8, female = 9; age range, 13-68 years) with clinically proven or suspicious metastatic pheochromocytoma or paraganglioma were included in this prospective study. Twelve patients underwent all three modalities, whereas five patients underwent (68)Ga-DOTATATE and (131)I-MIBG without (18)F-FDG. A composite reference standard derived from anatomical and functional imaging findings, along with histopathological information, was used to validate the findings. Results were analysed on a per-patient and on per-lesion basis. Sensitivity and accuracy were assessed using McNemar's test.


RESULTS
On a per-patient basis, 14/17 patients were detected in (68)Ga-DOTATATE, 7/17 patients in (131)I-MIBG, and 10/12 patients in (18)F-FDG. The sensitivity and accuracy of (68)Ga-DOTATATE, (131)I-MIBG and (18)F-FDG were (93.3 %, 94.1 %), (46.7 %, 52.9 %) and (90.9 %, 91.7 %) respectively. On a per-lesion basis, an overall of 472 positive lesions were detected; of which 432/472 were identified by (68)Ga-DOTATATE, 74/472 by (131)I-MIBG, and 154/300 (patient, n = 12) by (18)F-FDG. The sensitivity and accuracy of (68)Ga-DOTATATE, (131)I-MIBG and (18)F-FDG were (91.5 %, 92.6 % p < 0.0001), (15.7 %, 26.0 % p < 0.0001) and (51.3 %, 57.8 % p < 0.0001) respectively. Discordant lesions were demonstrated on (68)Ga-DOTATATE, (131)I-MIBG and (18)F-FDG.


CONCLUSIONS
Ga-DOTATATE PET/CT shows high diagnostic accuracy than (131)I-MIBG scintigraphy and (18)F-FDG PET/ CT in mapping metastatic pheochromocytoma and paraganglioma.

Back to the Future: From Klockars' Model of Effective Supervision to Evidence-Based Practice in Probation

Three contemporary models of probation supervision can be differentiated, based on the extent to which they focus on protecting community safety (surveillance model), promoting offender rehabilitation (treatment model), or both (hybrid model). Hybrid models combine dual roles of controlling and caring for probationers. A quarter century ago, Klockars (1972) articulated a theory to describe how the ‘‘synthetic’’ officer reconciles these dual roles to achieve a broader base of power for behavior change and more positive outcomes than the ‘‘law enforcement’’ officer or ‘‘therapeutic agent.’’ In this article, we apply Klockar’s theory to compare modern models of supervision in their (a) theoretical coherence and (b) effectiveness, at both the officer and program level, and for both general probationers and probationers with mental disorder. The weight of the evidence for both types of probationers supports the hybrid model. Going back to Klockar’s theory may ultimately inform officers’ understanding and adoption of hybrid strategies to more effectively supervise probationers.
Comparison of peri-articular liposomal bupivacaine and standard bupivacaine for postsurgical analgesia in total knee arthroplasty: A systematic review and meta-analysis.

OBJECTIVE
This meta-analysis aimed to compare the efficacy and safety of intraoperative peri-articular liposomal bupivacaine and standard bupivacaine in patients undergoing total knee arthroplasty.


METHODS
A systematic search was performed in Medline (1966-2016.9), PubMed (1966-2016.9), Embase (1980-2016.9), ScienceDirect (1985-2016.9) and the Cochrane Library. Only high-quality studies were selected. Meta-analysis was performed using Stata 11.0 software.


RESULTS
Three randomized controlled trials (RCTs) and two non-randomized controlled trials (Non-RCTs), including 1214 patients met the inclusion criteria. The present meta-analysis indicated that there were significant differences between groups in terms of visual analogue scale (VAS) score at 24 h (SMD = -0.241, 95% CI: -0.374 to -0.108, P = 0.000), VAS score at 48 h (SMD = -0.124, 95% CI: -0.256 to 0.009, P = 0.0068), morphine equivalent consumption on POD 1 (SMD = -0.275, 95% CI: -0.398 to -0.153, P = 0.000) and incidence of nausea (RD = 0.038, 95% CI: 0.001 to 0.074, P = 0.042) and vomiting (RD = 0.38, 95% CI: 0.003 to 0.072, P = 0.032).


CONCLUSION
Compared to standard bupivacaine, intraoperative peri-articular liposomal bupivacaine infiltration promotes superior pain relief and less morphine consumption after total knee arthroplasty. In addition, there were fewer side effects associated with liposomal bupivacaine infiltration.
Application of LSVT BIG intervention to address gait, balance, bed mobility, and dexterity in people with Parkinson disease: a case series.

BACKGROUND AND PURPOSE
Lee Silverman Voice Treatment Big (LSVT BIG) is characterized by intensive exercising of high-amplitude movements to overcome bradykinesia and hypokinesia in patients with Parkinson disease (PD). The aim of the present case series was to explore possible beneficial effects of LSVT BIG training on gait, balance, bed mobility, and dexterity.


CASE DESCRIPTION
Three patients with mild to moderate PD (all male; aged 52, 54, and 70 years; Hoehn & Yahr stages I-III) completed a 4-week LSVT BIG training program (16 individual 1-hour sessions) and an intensive home training program in accordance with the LSVT BIG protocol. Two certified LSVT BIG physical therapists delivered the LSVT BIG training sessions.


OUTCOMES
The outcome measures for gait and balance included the Functional Gait Assessment (FGA), Functional Reach Test (FRT), Timed "Up & Go" Test (TUG), Freezing of Gait Questionnaire (FOGQ), and motor score on part III of the Unified Parkinson's Disease Rating Scale (UPDRS III). Bed mobility was addressed using the Lindop Parkinson's Disease Mobility Assessment (LPA). The Nine-Hole Peg Test (9HPT) was used to measure dexterity. The 3 patients performed better on balance and gait assessments, as indicated by increased scores on the FRT and FGA (all 3 patients) and decreased scores on the TUG, FOGQ, and UPDRS III, of which scores of the FRT and UPDRS III achieved the minimal detectable change. Furthermore, the patients were quicker in tasks related to bed mobility (LPA). The patients' dexterity skills did not improve for their dominant (right) hand (9HPT).


DISCUSSION
This case series suggests that the LSVT BIG may be beneficial for gait, balance, and bed mobility. Future work is needed to ascertain the effectiveness by means of randomized controlled trials.
Pemphigus vulgaris in Iran: a clinical study of 140 cases.

BACKGROUND
Pemphigus vulgaris (PV) is a rare autoimmune blistering disease of the skin and mucous membranes. It varies in its clinical profile and epidemiologic characteristics in different parts of the world.


OBJECTIVE
To determine the clinical features of PV in Iran in a prospective manner.


METHODS
The study included 140 patients with newly registered PV attending our dermatology clinic between January 2003 and June 2004. RESULTS The mean age at the onset of the disease was 41.5 +/- 15.7 years, with a female to male ratio of 1.59 : 1. At presentation to our clinic, both skin and mucosal involvement was observed in 95 patients (67.9%). Cutaneous lesions without the involvement of the mucous membranes were seen in nine patients (6.4%), and exclusive mucosal involvement was present in 36 patients (25.7%). The most common initial localization of the disease was the oral cavity, which was involved in 93 patients (77.5%). The most frequent cutaneous and mucosal sites involved were the thorax and oral cavity, respectively.


CONCLUSION
Although minor differences were noted, the results of this study are in relatively good agreement with the literature with regard to the age, gender, and initial presentation of PV in Iran. Some skin sites, such as the scalp, thorax, and axilla, may be more commonly affected in men. Patients with initial mucosal lesions were significantly younger than those with initial cutaneous involvement. Mucosal lesions other than the oral mucosa may be more common than previously thought.
Combined therapy using Q-switched ruby laser and bleaching treatment with tretinoin and hydroquinone for periorbital skin hyperpigmentation in Asians.

BACKGROUND
Periorbital skin hyperpigmentation, so-called dark circles, is of major concern for many people. However, only a few reports refer to the morbidity and treatment, and as far as the authors know, there are no reports of the condition in Asians.


METHODS
A total of 18 Japanese patients underwent combined therapy using Q-switched ruby laser to eliminate dermal pigmentation following topical bleaching treatment with tretinoin aqueous gel and hydroquinone ointment performed initially (6 weeks) to reduce epidermal melanin. Both steps were repeated two to four times until physical clearance of the pigmentation was confirmed and patient satisfaction was achieved. Skin biopsy was performed at baseline in each patient and at the end of treatment in three patients, all with informed consent. Clinical and histologic appearances of periorbital hyperpigmentation were evaluated and rated as excellent, good, fair, poor, or default.


RESULTS
Seven of 18 patients (38.9 percent) showed excellent clearing after treatment and eight (44.4 percent) were rated good. Only one (5.6 percent) was rated fair and none was rated poor. Postinflammatory hyperpigmentation was observed in only two patients (11.1 percent). Histologic examination showed obvious epidermal hyperpigmentation in 10 specimens. Dermal pigmentation was observed in all specimens but was not considered to be melanocytosis. Remarkable reduction of dermal pigmentation was observed in the biopsy specimens of three patients after treatment.


CONCLUSION
The new treatment protocol combining Q-switched ruby laser and topical bleaching treatment using tretinoin and hydroquinone is considered effective for improvement of periorbital skin hyperpigmentation, with a low incidence of postinflammatory hyperpigmentation.
MRI predictors of treatment response for perianal fistulizing Crohn disease in children and young adults

Magnetic resonance imaging (MRI) is considered the imaging standard for diagnosis and characterization of perianal complications associated with Crohn disease in children and adults. To define MRI criteria that could act as potential predictors of treatment response in fistulizing Crohn disease in children, in order to guide more informed study interpretation. We performed a retrospective database query to identify all children and young adults with Crohn disease who underwent serial MRI studies for assessment of perianal symptoms between 2003 and 2010. We examined imaging features of perianal disease including fistula number, type and length, presence and size of associated abscess, and disease response/progression on follow-up MRI. We reviewed imaging studies and electronic medical records. Statistical analysis, including logistic regression, was performed to associate MR imaging features with treatment response and disease progression. We included 36 patients (22 male, 14 female; age range 8–21 years). Of these, 32 had a second MRI exam and 4 had clinical evidence of complete response, obviating the need for repeat imaging. Of the parameters analyzed, presence of abscess, type of fistula according to the Parks classification, and multiplicity were not predictors of treatment outcome. Maximum length of the dominant fistula and aggregate fistula length in the case of multiple fistulae were the best predictors of treatment outcome. Maximum fistula length <2.5 cm was a predictor of treatment response, while aggregate fistula length ≥2.5 cm was a predictor of disease progression. Perianal fistula length is an important imaging feature to assess on MRI of fistulizing Crohn disease.
