Aspect-Oriented Sentiment Analysis: A Topic Modeling-Powered Approach
Authors: Anoop V.S. , Asharaf S. 
Published: December 2018

Abstract
Because of exponential growth in the number of people who purchase products online, e-commerce organizations are vying for each other to offer innovative and improved services to its customers. Current platforms give its customers innovative services such as product recommendations based on their purchase histories and location, product comparison, and most importantly, a platform for expressing their experience and feedback. It is important for any e-commerce organization to analyze this feedback and to find out the sentiment of the customers for giving them better products and services. As large reviews may contain feedback in a mixed manner where a customer gives his opinion on different product features in the same review, finding out the exact sentiment is tedious. This work proposes aspect-specific sentiment analysis of product reviews using a well-sophisticated topic modeling algorithm called latent Dirichlet allocation (LDA). The topic words, thus, extracted are mapped with various aspects of an entity to perform the aspect-specific sentiment analysis on product reviews. Experiments with synthetic and real dataset show promising results compared to existing methods of sentiment analysis.

Published: December 2018

Abstract
A novel and useful extraction spectrophotometric method for the rapid determination of uranium and free acidity in nuclear fuel process samples using the reagent, 2,3-dihydroxynaphthalene as an extractant as well as color forming agent is described. Uranium at milligram level forms a yellowish- orange anionic complex with the ligand, 2,3-dihydroxynaphthalene over a pH range, 10–12. This anionic complex is easily extracted into ethylacetate as an ion-pair complex with cetyltrimethylammonium cation (CTA+). The absorbance of the ion-pair complex in ethylacetate is measured at 390 nm. The molar absorptivity and Sandell’s sensitivity of the system being 5.0×103 L·mol−1 cm−1 and 0.047 μg cm−2, respectively at 390 nm. This very reagent (2,3-dihydroxynaphthalene) also forms a yellowish-orange nitro product with free nitric acid (HNO3) in the presence of concentrated sulfuric acid. This nitro- product is easily extracted into the same solvent (ethylacetate) and absorbs maximum at 380 nm. The molar absorptivity (ε) and Sandell’s sensitivity of the system being 2.4×103 L·mol−1 cm−1 and 0.027 μg cm−2, respectively. By using the single chromophoric agent (2,3-dihydroxynaphthalene), both uranium and free acidity can be easily and reliably determined separately in the process solution. The relative standard deviations (RSD) are in the range, 0.5–2.0% and 1.5–2.0%, respectively for uranium and free nitric acid determinations. The method has been applied to nuclear fuel process solutions, and the results obtained have been found to be favorably comparable with those obtained from standard methods.

Abstract
Festa, L, Tarperi, C, Skroce, K, Boccia, G, Lippi, G, La Torre, A, and Schena, F. Effects of flywheel strength training on the running economy of recreational endurance runners. J Strength Cond Res 33(3): 684–690, 2019—Running economy (RE) has been defined as the most important determining factor in endurance performance in both elite and recreational runners. The purpose of this study was to evaluate the effect of flywheel strength training (FST) and high-intensity training (HIT) protocols on RE and strength parameters in a group of recreational runners. Twenty-nine recreational runners were recruited to take part in the study and were randomly assigned to FST (n = 9; 44.5 ± 6.0 years; V̇o
2max 48.8 ± 5.2 ml·min−1·kg−1), HIT (n = 9; 42.2 ± 8.6 years; V̇o
2max 50.3 ± 3.7 ml·min−1·kg−1), or low-intensity training (LIT) (n = 11; 45.4 ± 8.0 years; V̇o
2max 50.2 ± 6.8 ml min−1 kg−1) groups. Before and after 8 weeks of an experimental period, maximal oxygen uptake (V̇o
2max), ventilatory thresholds (VTs), maximal dynamic force (1 repetition maximum [1RM]), and anthropometric data were evaluated. The FST group showed significant increases (p < 0.05) in 1RM and RE. No differences were found in the other groups. Significative changes are found for all groups on average speed on 2 and 10 km (p < 0.05). Anthropometric data were unchanged after the training period. The results of this study indicate that in recreational runners, FST seems able to obtain improvements in RE and neuromuscular adaptation.

Published: December 2018

Abstract
Monitoring techniques, used to assess the condition of infrastructures, have been impacted by the rapid developments in remote sensing technology. While these technologies have improved performance evaluation, cogent procedures for evaluating ground movements have yet to be developed. This article presents an application of the three-dimensional terrestrial laser scanning (3D-TLS) technology for assessing the performance of bridge infrastructures, including highway embankments, bridge decks, approach slabs, abutments, and columns supported on drilled shafts. In this research study, a framework was developed, using 3D-TLS technology, to evaluate the ground movements. The survey process, variables, and analysis were demonstrated by performing the field operations at a rehabilitated bridge infrastructure located in North Texas. The analysis depicted vertical movements that were experienced by the approach slab during different time periods. The validation of 3D-TLS results was performed by comparing the vertical movements from the four horizontal inclinometers installed underneath the pavement. The comparison studies revealed similar movement patterns of both inclinometers and processed scans, while the latter provided detailed soil movements over a larger area.
Degeneration of ipRGCs in Mouse Models of Huntington's Disease Disrupts Non-Image-Forming Behaviors Before Motor Impairment

Published: December 2018

Intrinsically photosensitive retinal ganglion cells (ipRGCs), which express the photopigment melanopsin, are photosensitive neurons in the retina and are essential for non-image-forming functions, circadian photoentrainment, and pupillary light reflexes. Five subtypes of ipRGCs (M1–M5) have been identified in mice. Although ipRGCs are spared in several forms of inherited blindness, they are affected in Alzheimer's disease and aging, which are associated with impaired circadian rhythms. Huntington's disease (HD) is an autosomal neurodegenerative disease caused by the expansion of a CAG repeat in thehuntingtingene. In addition to motor function impairment, HD mice also show impaired circadian rhythms and loss of ipRGC. Here, we found that, in HD mouse models (R6/2 and N171-82Q male mice), the expression of melanopsin was reduced before the onset of motor deficits. The expression of retinal T-box brain 2, a transcription factor essential for ipRGCs, was associated with the survival of ipRGCs. The number of M1 ipRGCs in R6/2 male mice was reduced due to apoptosis, whereas non-M1 ipRGCs were relatively resilient to HD progression. Most importantly, the reduced innervations of M1 ipRGCs, which was assessed by X-gal staining in R6/2-OPN4Lacz/+male mice, contributed to the diminished light-induced c-fos and vasoactive intestinal peptide in the suprachiasmatic nuclei (SCN), which may explain the impaired circadian photoentrainment in HD mice. Collectively, our results show that M1 ipRGCs were susceptible to the toxicity caused by mutant Huntingtin. The resultant impairment of M1 ipRGCs contributed to the early degeneration of the ipRGC–SCN pathway and disrupted circadian regulation during HD progression.SIGNIFICANCE STATEMENTCircadian disruption is a common nonmotor symptom of Huntington's disease (HD). In addition to the molecular defects in the suprachiasmatic nuclei (SCN), the cause of circadian disruption in HD remains to be further explored. We hypothesized that ipRGCs, by integrating light input to the SCN, participate in the circadian regulation in HD mice. We report early reductions in melanopsin in two mouse models of HD, R6/2, and N171-82Q. Suppression of retinal T-box brain 2, a transcription factor essential for ipRGCs, by mutant Huntingtin might mediate the reduced number of ipRGCs. Importantly, M1 ipRGCs showed higher susceptibility than non-M1 ipRGCs in R6/2 mice. The resultant impairment of M1 ipRGCs contributed to the early degeneration of the ipRGC–SCN pathway and the circadian abnormality during HD progression.
Comparative stable walking gait optimization for small-sized biped robot using meta-heuristic optimization algorithms
Authors: Huan Tran Thien , Anh Ho Pham Huy 
Published: December 2018

This paper proposes a new way to optimize the biped walking gait design for biped robots that permits stable and robust stepping with pre-set foot lifting magnitude. The new meta-heuristic CFO-Central Force Optimization algorithm is initiatively applied to optimize the biped gait parameters as to ensure to keep biped robot walking robustly and steadily. The efficiency of the proposed method is compared with the GA-Genetic Algorithm, PSO-Particle Swarm Optimization and Modified Differential Evolution algorithm (MDE). The simulated and experimental results carried on the prototype small-sized humanoid robot demonstrate that the novel meta-heuristic CFO algorithm offers an efficient and stable walking gait for biped robots with respect to a pre-set of foot-lift height value.

ÖZET

Ektopik paratiroid bezleri, gözden kaçırıldıklarında, persistan veya
rekürren hiperparatiroidizmin ortak bir etiyolojisini oluştururlar. Ektopik
paratiroid bezleri, embriyogenez sürecinde anormal göçten kaynaklanır ve
başarılı bir identifikasyon olmaması paratiroid cerrahisinde başarı eksikliğine
neden olabilir. Ektopik inferior paratiroidler anterior mediastende, timus veya
tiroid bezinde en sık görülürken, ektopik superior paratiroidler için en sık
görülen pozisyon trakeoözofageal oluk ve retro özofageal bölgedir. Boyun
ultrasonografisi, 99mTc Sestamibi taraması ve tek foton emisyonlu bilgisayarlı
tomografi (SPECT) veya CT (SPECT / CT) ektopik paratiroidlerin tanısal
doğruluğunu arttıran görüntüleme yöntemleridir. Paratiroid dokusu için şüpheli
bir lezyonun ince iğne aspirasyon sitolojisi ve aspire edilen materyalin
paratiroid hormonu ölçümü ektopik bezlerin preoperatif lokalizasyonuna yardımcı
olur. Cerrahi inceleme için yaygın alanlar, üst paratiroidler için üst tiroid
kutbu, üst tiroid vasküler yapıları ve servikal özofagus, inferior
paratiroidler için karotis arter bifurkasyonu ve timustur. Radyografik olarak
başarılı lokalizasyondan sonra minimal invaziv paratiroidektomi, postoperatif
hızlı parathormon ölçümü ile desteklenerek ektopik paratiroid adenomu olan
hastalarda cerrahi sonuçları önemli ölçüde artırmaktadır.

ABSTRACT

Ectopic parathyroid
glands, when missed, form a common etiology of persistent or recurrent
hyperparathyroidism. Ectopic parathyroid glands originate from abnormal
migration in the embryogenesis process and lack of a successful identification
may lead to a lack of success in parathyroid surgery. While ectopic inferior
parathyroids are most common in the anterior mediastinum, thymus or thyroid
gland, the most common position for ectopic superior parathyroids is the
tracheoesophageal groove and the retro esophageal region. Neck ultrasonography, 99mTc Sestamibi
scanning and single-photon emission computed tomography (SPECT) or CT (SPECT /
CT) are imaging modalities that increase the diagnostic accuracy of ectopic
parathyroids. The fine needle aspiration cytology of the suspected lesion for
parathyroid tissue and the parathyroid hormone measurement of the aspirated
material help preoperative localization of ectopic glands. Common areas for
surgery are upper thyroid pole, upper thyroid vascular structures and cervical
esophagus for upper parathyroids and bifurcation of the carotid artery and
thymus for inferior parathyroids. After radiographic successful localization,
minimally invasive parathyroidectomy is supported by postoperative rapid
parathyroid hormone measurement, which significantly increases surgical
outcomes in patients with ectopic parathyroid adenoma.

ABSTRACT:This research questions whether English language teaching courses offered by Brazilian public universities equip the next generation of teachers with the necessary skills to teach via distance learning through online environments. The methodology used is quantitative in nature and considers 118 universities that offer English Language and Literature courses. Their curricula were analyzed solely to investigate if the courses offered any modules related to distance learning. Only four institutions propose entire modules that deal with distance education although they are elective. In order to propose an alternative to this issue, a suite of three modules related to technology, distance teaching and learning are presented. TPACK model was used as a guide to analyze the proposed modules. The development of the modules could establish a more solid and holistic pre-service teacher education, so that pre-service teachers can be prepared to teach in online and blended environments.KEYWORDS: pre-service training; distance education; TPACK; public universities.
