London’s Geographic Knowledge Network and the Anson Account (1748)

Parker outlines the major players and interdependent relationships within London that worked together to bring the Pacific to the printed page, followed by an analysis of the publication of a particular travel account, Anson’s Voyage Round the World (London: John and Paul Knapton, 1748). By tracing how information was gathered at sea and fixed in text and on maps, it is possible to see the international collaborative, yet competitive, effort necessary to create a world on paper. Such a paper world was a vital tool that spurred European expansion later in the eighteenth and nineteenth centuries.
Pedestrian Detection

A program that detects people in images has a multitude of potential applications, including tracking for biomedical applications or surveillance, activity recognition for person-device interfaces (device control, video games), organizing personal picture collections, and much more. However, detecting people is difficult, as the appearance of a person can vary enormously because of changes in viewpoint or lighting, clothing style, body pose, individual traits, occlusion, and more. It then makes sense that the first people detectors were really detectors of pedestrians, that is, people walking at a measured pace on a sidewalk, and viewed from a fixed camera. Pedestrians are nearly always upright, their arms are mostly held along the body, and proper camera placement relative to pedestrian traffic can virtually ensure a view from the front or from behind (Figure 1). These factors reduce variation of appearance, although clothing, illumination, background, occlusions, and somewhat limited variations of pose still present very significant challenges.
Knee arthrodesis with simultaneous lengthening using the Ilizarov method.

OBJECTIVE
To determine whether knee arthrodesis with simultaneous lengthening using the Ilizarov method for a nonreconstructable knee joint with bone loss and infection is a successful salvage procedure.


DESIGN
Retrospective review of patients.


SETTING
University hospital-based orthopaedic practice.


PATIENTS
From 1999 to 2001, 4 consecutive patients with a nonreconstructable knee joint, bone loss, and infection after trauma underwent knee arthrodesis with simultaneous lengthening.


INTERVENTION
Arthrodesis of the knee with simultaneous limb lengthening through an osteotomy of the tibia and/or femur and the use of an Ilizarov frame. External bone stimulation was used at the knee arthrodesis site and the lengthening sites. Application of this device began during the early distraction phase and continued until frame removal.


MAIN OUTCOME MEASURES
Bony union at the arthrodesis and bone lengthening sites, alignment of the lower extremity, limb length discrepancy, infection, pain, and outcome scales (SF-36 scores and American Academy of Orthopaedic Surgeons lower limb modules).


RESULTS
Bony union of the knee arthrodesis and lengthening sites and good alignment were achieved in all 4 patients. Mean amount of lengthening was 5.4 cm (range 2.5-11.5 cm). Average time in frame was 11 months (range 6-17 months). Limb length discrepancy after treatment averaged 1.8 cm (range 0.6-3.7 cm). Mean duration of follow-up after frame removal was 35 months (range 28-48 months). At follow-up, infection had not recurred, pain was not present, and assistive devices were not needed for ambulation. Average SF-36 scores improved in all 8 categories, and the average American Academy of Orthopaedic Surgeons lower limb modules improved from a mean of 33 (range 11-37) to a mean of 68 (range 51-76).


CONCLUSION
Knee arthrodesis with simultaneous lengthening can be performed successfully using the Ilizarov method. It enables surgeons to optimize limb length during knee arthrodesis. The use of external fixation and the avoidance of internal implants may be advantageous in the presence of or history of infection. The Ilizarov frame provides stability that allows weight bearing during treatment.
Spline-Based Model for Digital Predistortion of Wide-Band Signals for High Power Amplifier Linearization

Different linearization techniques have been proposed to linearize Power Amplifiers (PAs) and improve the PA efficiency for non-constant envelope modulation schemes. Among all the linearization techniques, Digital Predistortion (DPD) is one of the most cost effective. For wider bandwidth applications, PA memory effects can no longer be ignored. Therefore in order to achieve a higher linearization performance, the Predistorter (PD) requires to compensate for memory nonlinearities. In this paper a new PD model based on piecewise polynomial approximation in the form of splines is described and compared with memory polynomial PD. The purpose of the spline PD is to increase the approximation accuracy and/or reduce the complexity. Simulation results with 16 Quadrature Amplitude Modulation (QAM) show a significant improvement in Adjacent Channel Power Ratio (ACPR) for a Wiener-Hammerstein power amplifier model. A set-up to perform the measurements on a 100 watt High Power Amplifier (HPA) is also developed. The experiments are carried out on both an uplink WCDMA and a crest-reduced two-carrier WCDMA signal. The results show that a higher linearization performance is obtained by using spline basis functions as compared to conventional memory polynomial PD.

3-D analysis of breast morphology changes after inverted T-scar and vertical-scar reduction mammaplasty over 12 months.

One major objective of all types of breast reduction procedures is to achieve a long-lasting, stable and aesthetically pleasing three-dimensional (3-D) breast shape, but current surgical outcome evaluation is limited. This study compares the extent of soft-tissue oedema and breast tissue migration related to 3-D breast morphology changes after inverted T-scar and vertical-scar breast reduction over 12 months. 3-D breast surface scans of patients undergoing inverted T-scar (n=52 breasts) and vertical-scar (n=44 breasts) reduction mammaplasty were obtained preoperatively and 2-3 days, 1 week, 1 month, 3 months, 6 months, 9 months and 12 months postoperatively. 3-D images were analysed at each time point comparing distances, 3-D breast contour deviations (%), breast surface (cm2) and volume (cc) measurements including volumetric distribution between the upper portion (UP) and the lower portion (LP) of the breast (%). Total postoperative breast volume decreased by 11.7% (T-scar) and by 7.8% (vertical-scar) during the first 3 months (both p<0.001) without relevant changes in the following months, indicating that soft-tissue oedema is resolved after 3 months. The T-scar (vertical-scar) group showed a preoperative UP to LP volumetric distribution of 43:57% (45:55%) versus 86:14% (91:9%) immediately after surgery. Breast tissue significantly redistributes (both p=0.001) from the UP to the LP during the first postoperative year by 16.5% (T-scar) and 21% (vertical-scar), resulting in a final UP to LP ratio of 70:30% for both techniques, without further breast contour deviations (both p>0.05) after 6 months (T-scar) and 9 months (vertical-scar). Breast morphological changes after reduction mammaplasty are completed after a period of 3-6 months in the T-scar group and 6-9 months in the vertical-scar group.
Understanding online purchase intentions: contributions from technology and trust perspectives

Received: 12 July 2000 Revised: 20 August 2001 : 30 July 2002 Accepted: 15 October 2002 Abstract This paper explores factors that influence consumer’s intentions to purchase online at an electronic commerce website. Specifically, we investigate online purchase intention using two different perspectives: a technology-oriented perspective and a trust-oriented perspective. We summarise and review the antecedents of online purchase intention that have been developed within these two perspectives. An empirical study in which the contributions of both perspectives are investigated is reported. We study the perceptions of 228 potential online shoppers regarding trust and technology and their attitudes and intentions to shop online at particular websites. In terms of relative contributions, we found that the trust-antecedent ‘perceived risk’ and the technology-antecedent ‘perceived ease-of-use’ directly influenced the attitude towards purchasing online.

Treatment for meibomian gland dysfunction and dry eye symptoms with a single-dose vectored thermal pulsation: a review.

PURPOSE OF REVIEW
Meibomian gland dysfunction (MGD) is understood to be a highly prevalent, chronic progressive disease and the leading cause of dry eye. All available published peer-reviewed results of the novel vectored thermal pulsation therapy for patients with MGD are investigated.


RECENT FINDINGS
The PubMed and meeting abstract search revealed a total of 31 peer-reviewed reports on vectored thermal pulsation therapy at the time of the search (eight manuscripts and 23 meeting abstracts). All manuscripts evidence a significant increase in meibomian gland function (∼3×) and symptom improvement post a single 12-min treatment. Additional reported objective measures such as osmolarity, tear break-up time, or lipid layer thickness also increased as a result of the therapy; however, not all findings were statistically significant. The randomized controlled studies evidence sustained gland function and symptom relief lasting out to 12 months. The uncontrolled case series evidence significantly longer duration of effect.


SUMMARY
A single 12 minute vectored thermal pulsation treatment allows for reducing dry eye symptoms, improving meibomian gland function and other correlates of the ocular surface health.
Carpal tunnel syndrome in manual wheelchair users with spinal cord injury: a cross-sectional multicenter study.

OBJECTIVE
To investigate relationships between carpal tunnel syndrome, functional status, subject demographics, physical examination findings, and median nerve conduction study findings in manual wheelchair users with paraplegia.


DESIGN
Multicenter cross-sectional study. One hundred twenty-six manual wheelchair-using individuals with chronic paraplegia answered self-administered questionnaires on demographics, symptoms, and functional status. They underwent physical examination specific for carpal tunnel syndrome and upper-limb nerve conduction studies.


RESULTS
Fifty-seven percent of subjects had symptoms (72.2% bilateral); hand numbness was most common. Sixty percent of subjects had carpal tunnel syndrome physical examination findings (59.2% bilateral). Those with physical examination findings were more likely to have longer duration of injury (P = 0.003). Seventy-eight percent of subjects had electrophysiologic evidence of median mononeuropathy. Symptomatic subjects had significantly greater median-ulnar motor latency difference in the dominant hand (P = 0.02) and smaller compound muscle action potential amplitudes bilaterally (dominant hand, P = 0.01; nondominant hand, P = 0.04). Persons with carpal tunnel syndrome symptoms and physical examination findings had significantly worse functional status (symptoms, P < 0.001; physical examination, P = 0.02) and symptom severity scores (symptoms, P < 0.001; physical examination, P = 0.01), but a similar difference between subjects with and without median mononeuropathy was not seen. Logistic regression analysis revealed that the presence of symptoms was predicted by median-ulnar motor latency difference in the dominant hand (odds ratio, 4.38; 95% confidence interval 1.72-11.14) and sensory nerve action potential amplitude in the nondominant hand (odds ratio, 0.97; 95% confidence interval, 0.94-0.99).


CONCLUSIONS
The interaction among symptoms, physical examination, and nerve conduction study findings is complex. Carpal tunnel syndrome and median mononeuropathy are highly prevalent and functionally significant. This study highlights the need for primary prevention and patient education for preserving upper-limb function.

Gravitational fields on a noncommutative space

Abstract Noncommutative three-dimensional gravity can be described in terms of a noncommutative Chern–Simons theory. We extend this structure and also propose an action for gravitational fields on an even-dimensional noncommutative space. The action is worked out in some detail for fields on a noncommutative CP 2 and on  S 4 .
Sural artery perforator flap with posterior tibial neurovascular decompression for recurrent foot ulcer in leprosy patients

Introduction: The sensory loss and alteration of the shape of the foot make the foot liable to trauma and pressure, and subsequently cause more callus formation, blisters, and ulcers. Foot ulcers usually are liable to secondary infection as cellulitis or osteomyelitis, and may result in amputations. Foot ulcers are a major problem and a major cause of handicaps in leprosy patients. The current study is to present our clinical experience and evaluate the use of sural flap with posterior tibial neurovascular decompression (PTND) in recurrent foot ulcers in leprosy patients. Patient and methods: A total number of 9 patients were suffering from chronic sequelae of leprosy as recurrent foot ulcers. All the patients were reconstructed with the reverse sural artery fasciocutaneous flap with posterior tibial neurovascular decompression from September 2012 to August 2015. Six patients were male and three were female with a mean age of 39.8 years (range, 30-50 years). All the soft tissue defects were in the weight-bearing area of the inside of the foot. The flap sizes ranged from 15/4 to 18/6 cm. Mean follow-up period was 21.2 months (range, 35-2 months). Results: All the flaps healed uneventfully. There was no major complication as total flap necrosis. Only minor complications occurred which were treated without surgical intervention except in two patients who developed superficial necrosis of the skin paddle. Surgical debridement was done one week later. The flap was completely viable after surgery, and the contour of the foot was restored. We found that an improvement of sensation occurred in those patients in whom the anesthesia started one year ago or less and no sensory recovery in patient in whom the anesthesia had lasted for more than two years. Conclusion: The reverse sural artery flap with posterior tibial neurovascular decompression provides a reliable method for recurrent foot soft tissue reconstruction in leprosy patients with encouraging function and aesthetic outcomes. It is a quick and easy procedure.
Motor Skill Competency and Physical Activity in Elementary School Students

©ARC Page | 76 Abstract Background: Childhood mastery of manipulative skills predicted their adolescent learning and mastering specialized skills needed for successful participation in sports and activity. This study investigated relationships between levels of manipulative skill competency and participation in physical activity in school-aged children. Methods: 265 fifth-grade students voluntarily participated in this study. The students’ skill performance in four basic specialized manipulative skills was assessed using reliable and valid assessment rubrics with processand product-oriented criteria. The students’ daily physical activity was assessed using a 7-day daily physical activity (PA) log. Data were analyzed with descriptive statistics and univariate analyses, Pearson bivariate correlation, and multiple R-squared liner regression methods. Results: The results of regression models indicated that overall skill competency in four manipulative skills significantly contributed to weekly PA minutes for the total sample and girls, but not for boys. Specifically, girls’ competency in soccer skills was a significant predictor of weekly PA minutes. Independent sample t-tests revealed that both boys and girls in the Skill-Competent group spent a significant amount of time in PA than their counterparts in the Skill-Incompetent group. Conclusions: Manipulative skill competency plays a significant role in participation in PA inside and outside of school for school-aged children, especially for girls. Improving girls’ manipulative skill competency is a key determinant of PA behavior for girls.

Periodontitis and Buerger’s Disease: Recent Advances

Buerger's disease (BD) is a relatively rare thrombotic, occlusive and non-atherosclerotic clinical syndrome of unknown etiology. In recent years, numerous epidemiological studies confirmed the strong association between chronic anaerobic periodontal infection and development of cardiovascular diseases, including BD. Therefore, the aim of this study is to clarify association between periodontal pathogens and Buerger's disease. Confirmation of presence and identification of periopathogens in patients with BD can be considered crucial in developing novel therapies for BD. Further, periodontal therapy will lead to eventual improvement of BD patients' condition.
Optimal production and shipment models for a single-vendor-single-buyer integrated system

This paper develops a more general production-inventory model for a single-vendor–single-buyer integrated system. Unlike the hitherto existing production-inventory models for the vendor–buyer system, the present model neither requires the buyer’s unit holding cost greater than the vendor’s nor assumes the structure of shipment policy. Secondly, the model is extended to the situation with shortages permitted, based on shortages being allowed to occur only for the buyer. Thirdly, the paper also presents a corresponding production-inventory model for a deteriorating item for the integrated system. The solution procedures are provided for finding the optimal production and shipment policies and illustrated with numerical examples. Three significant insights are shown: (1) no matter whether the buyer’s unit holding cost is greater than the vendor’s or not, the present model always performs best in reducing the average total cost as compared to the hitherto existing models; (2) if the buyer’s unit holding cost is less than the vendor’s, the optimal shipment policy for the integrated system will only comprise shipments with successive shipment sizes increasing by a fixed factor. It is different from that obtained by Hill [Hill, R.M., 1999. The optimal production and shipment policy for the single-vendor single-buyer integrated production-inventory problem. International Journal of Production Research 37, 2463–2475] for the opposite case; (3) when designing a single-vendor–single-buyer integrated system, making the buyer’s unit holding cost lower than the vendor’s is more beneficial to the system if shortages are not permitted to occur; otherwise it just reverses. 2006 Elsevier B.V.

CNN-SVM for Microvascular Morphological Type Recognition with Data Augmentation

This paper focuses on the problem of feature extraction and the classification of microvascular morphological types to aid esophageal cancer detection. We present a patch-based system with a hybrid SVM model with data augmentation for intraepithelial papillary capillary loop recognition. A greedy patch-generating algorithm and a specialized CNN named NBI-Net are designed to extract hierarchical features from patches. We investigate a series of data augmentation techniques to progressively improve the prediction invariance of image scaling and rotation. For classifier boosting, SVM is used as an alternative to softmax to enhance generalization ability. The effectiveness of CNN feature representation ability is discussed for a set of widely used CNN models, including AlexNet, VGG-16, and GoogLeNet. Experiments are conducted on the NBI-ME dataset. The recognition rate is up to 92.74% on the patch level with data augmentation and classifier boosting. The results show that the combined CNN-SVM model beats models of traditional features with SVM as well as the original CNN with softmax. The synthesis results indicate that our system is able to assist clinical diagnosis to a certain extent.
A Study of Recent Contributions on Information Extraction

This paper reports on modern approaches in Information Extraction (IE) and its two main sub-tasks of Named Entity Recognition (NER) and Relation Extraction (RE). Basic concepts and the most recent approaches in this area are reviewed, which mainly include Machine Learning (ML) based approaches and the more recent trend to Deep Learning (DL)
Constraints, lazy constraints, or propagators in ASP solving: An empirical analysis

Answer Set Programming (ASP) is a well-established declarative paradigm. One of the successes of ASP is the availability of efficient systems. State-of-the-art systems are based on the ground+solve approach. In some applications this approach is infeasible because the grounding of one or few constraints is expensive. In this paper, we systematically compare alternative strategies to avoid the instantiation of problematic constraints, that are based on custom extensions of the solver. Results on real and synthetic benchmarks highlight some strengths and weaknesses of the different strategies. (Under consideration for acceptance in TPLP, ICLP 2017 Special Issue.)
'Triangulation' Research Method as the Tool of Social Science Research

This article discusses 'triangulation' as a strategy for increasing the validity of evaluation and research findings. Triangulation is used to combine the advantages of both the qualitative and the quantitative approach. Each method offers specific advantages as well as disadvantages. Recent developments in the philosophy of science have argued that the two traditions should not have a separate-but-equal status, and should instead interact. Triangulation is not aimed merely at validation but at deepening and widening one's understanding, and tends to support interdisciplinary research rather than a strongly bounded discipline of sociology or anthropology.
