A comparison of ultra-high-resolution CT target scan versus conventional CT target reconstruction in the evaluation of ground-glass-nodule-like lung adenocarcinoma.

Background The aim of this study was to determine whether the clinical value of scanned computed tomography (CT) images is higher when using ultra-high-resolution CT (U-HRCT) target scanning than conventional CT target reconstruction scanning in the evaluation of ground-glass-nodule (GGN)-like lung adenocarcinoma. Methods A total of 91 consecutive patients with isolated GGN-like lung adenocarcinoma were included in this study from April 2017 to June 2018. U-HRCT and conventional CT scans were conducted in all enrolled patients. Two experienced thoracic radiologists independently assessed image quality and made diagnoses. Based on the pathological results, the accuracies of U-HRCT target scanning and conventional CT target reconstruction for detecting morphological features on CT, including spiculation of GGNs, bronchial vascular bundles, solid components in the nodules, burr, vacuole, air bronchial signs, and fissure distortion, were calculated. All statistical analyses were performed using SPSS 17.0 software. Enumeration data were tested using the Chi-square test. A P value of <0.05 was considered statistically significant. Results When both techniques were compared with the pathological findings, the detection rate for CT images obtained using U-HRCT target scanning and conventional CT target reconstruction with regard to the spiculation of GGNs, bronchial vascular bundles, and solid components in the nodules were 78% vs. 61.5%, 72.5% vs. 54.9%, 65.9% vs. 49.5%, respectively. The presence of the spiculation of GGNs, bronchial vascular bundles, and solid components in the nodules in U-HRCT target scanning was significantly higher than that in conventional CT target reconstruction (all P<0.05). However, no significant difference was observed between the two techniques with regard to the burr, vacuole, air bronchial signs, and fissure distortion (all P>0.05). Conclusions When viewing GGNs, the detection rate was higher for U-HRCT target scanning than for conventional CT target reconstruction, and this improvement significantly enhanced the diagnostic accuracy of early lung adenocarcinoma.
User Adaptive Music Similarity with an Application to Playlist Generation

This thesis is about the generation of playlists for music. The distances between songs are calculated based on spectral shape features. Minimal user feedback (approval or rejection of proposed songs) is used besides song distances to generate playlists. Automatic feature selection is used to better fit the user’s needs. There are 4 different contributions to the current state of art: • The comparison of different distance measures and statistical models in the context of playlist generation. • A new way of using spectral shape features, extracting them in multiple dimensions and modelling them independently from each other instead of putting all spectral features together and just estimating one probability density function. • Introduction of additional song selection strategies for playlist generation. • Adaptive automatic feature selection in the context of playlist generation. The results of research work indicate that using a likelihood ratio hypothesis test distance using single Gaussians returns results comparable to the results of the more complicated distances operating on Gaussian mixture models. Furthermore, results show that more-sophisticated selection strategies are capable of handling feature spaces including less important features. The quality of the playlists can be further improved by means of user-adaptive automatic feature selection.
PEM fuel cell as energy source using fuzzy logic controller

A dynamic model of a proton exchange membrane (PEM) fuel cell (FC) has been developed to study its dynamic behaviors along with a fuzzy logic controller (FLC) to control the fuel flow to the reformer. The model can be used to study the dynamic behavior of the system in stand-alone and grid connected mode. The dynamic behavior of the fuel cell system with FLC and PI controller were studied and compared. The dynamic behavior of the system with FLC is found to be more improved as compared to that of the PI controller in terms of response time of the FC system in following the load demand to it. The use of FLC reduces the capacity of storage devices in stand-alone mode to meet the load requirement during transient periods. To meet the power demand set by the user and maintain inverter AC voltage at the desired value PI controllers were used.
Neuroimaging Studies of Task Switching

Two substantive challenges face any attempt to study task switching with neuroimaging methods. The first challenge is practical: Task switching is by essence a rapid and dynamic process, but neuroimaging methods almost exclusively rely on slowly-evolving hemodynamic measures of activity in static brain regions. The second challenge is conceptual: It is not always obvious how to translate the claims and terminology of cognitive and computational theories into clear and testable predictions about brain activity. In this chapter, we review methods and findings of studies that have attempted to address these important challenges. We conclude, with some optimism, that neuroimaging studies have provided valuable evidence on three core issues in task switching research: the cause of the behavioural cost associated with task switching, the degree to which task switching represents a coherent domain of study, and the extent to which different forms of task switching involve dissociable mechanisms. Looking to the future, we suggest that neuroimaging has substantial promise in linking task switching research to broader themes and issues in cognitive neuroscience. In this spirit, we identify shared methods and findings in task switching research and in the study of ‘retrieval sets’ in long-term memory, which collectively indicate the value of adopting a broader conception of task sets to incorporate the control of long-term memory processes.
Evidential Multisensor Fusion and Erroneous Management of Lanes for Autonomous Driving

Lane information is essential for safe autonomous driving. In this article, we present a multisensor fusion framework for ego and adjacent lanes with a novel fusion quality measure and dynamic lane mode strategies for erroneous management. The framework fuses road marking lines based on Dempster-Shafer theory and tracks lanes with a particle filter. Then, a quality measure for each line is computed, integrating sensor coherence, availability as well as temporal continuity. This quality is essential to deploy different lane management strategies in order to avoid integrating erroneous data. The proposed framework was evaluated in a lateral control architecture with autonomous driving on open roads and proved its robustness and availability.
The Design Techniques for High-Speed PAM4 Clock and Data Recovery

In this paper, some key techniques of clock and data recovery (CDR) are proposed for PAM4 format high-speed communication, including effective voltage level transitions selection, sampling location optimization and threshold adjustment. Based on these techniques, two 50Gbps PAM4 CDR were designed and fabricated in 65nm and 40nm, respectively. The measurement results show $3.4\times10^{-9}$ BER of 65nm PAM4 CDR and $8\times10^{-9}$ BER of 40nm PAM4 CDR.

Correlates of Physical Activity in Colorectal Cancer Patients Based on Health Promotion Model

Background Increasing attention is being given to physical activity in colorectal cancer patients. Some studies have explored a few correlates of physical activity separately. A contemporary study based on the Health Promotion Model may systematically broaden the understanding of physical activity in colorectal cancer patients. Objective To understand the status of physical activity in Chinese colorectal cancer patients and to explore the correlated factors. Methods A total of 168 adults with colorectal cancer were recruited at 3 tertiary hospitals in China. Participant data were collected on demographics, physical activity, biological factors, anxiety and depression, benefits/barriers to physical activity, self-efficacy, and social support. SAS 8.2 was used for statistical analysis, including descriptive analysis, correlation analysis, single factor analysis, and multiple stepwise regression analysis. Results Only 25.60% of colorectal cancer survivors reached the requirements of the Colorectal Cancer Survivorship Care Guidelines. Employment states, number of complications, fatigue, body image, depression, perception of benefits/barriers, and self-efficacy were closely correlated with physical activity in Chinese colorectal cancer patients. Conclusions The physical activity status of patients with colorectal cancer is not optimal. The correlated factors that nurses can take measures to improve are fatigue, body image, depression, perception of benefits/barriers, and self-efficacy, which may improve physical activity in colorectal cancer patients in China. Additional research is needed to determine if improving factors correlated with physical activity will assist with directly increasing physical activity. Implications for Practice Nurses should evaluate physical activity of colorectal cancer patients timely and play an active role in health promotion programs to improve colorectal cancer patients’ physical activity.

Objective: To evaluate the clinical and functional outcomes of patients subjected to surgical treatment of hallux rigidus by the percutaneous cheilectomy combined with Watermann and Moberg osteotomies. Methods: Between May 2017 and August 2018, the clinical outcomes of 7 patients with a diagnosis of hallux rigidus (HR) treated using the percutaneous technique were assessed using the American Orthopedic Foot and Ankle Society (AOFAS) scale, the visual analogue scale (VAS) for pain and hallux metatarsophalangeal joint range of motion measurements during the pre- and postoperative periods. Clinical and functional outcomes were followed up for a minimum of 6 months (mean of 8 months). Results: The range of motion of the metatarsophalangeal joint during the pre- and postoperative periods showed the following results: dorsiflexion increased on average from 28. 00º (± 15.63) to 44. 43º (± 17.33) (p = 0.006), demonstrating an effective gain in dorsal articular movement. Plantar flexion ranged on average from 27. 43º (± 2.22) to 24. 43º (± 5.28) (p = 0.228), with no significant difference between the evaluated periods. The AOFAS score increased on average from 52.71 (± 9.63) to 88.00 (± 8.10) (p < 0.01), representing important functional improvement. The VAS score decreased on average from 7.00 (± 1.52) to 2.14 (± 2.19) (p = 0.002), indicating a significant improvement in patient pain. No patient presented postoperative complications. Conclusion: The results of the present study demonstrated that cheilectomy combined with percutaneous Watermann and Moberg osteotomies is an effective surgical treatment for hallux rigidus, with satisfactory clinical and functional outcomes.

Correlation of Paraoxonase-1 with glycated hemoglobin and lipid profile among Sudanese diabetic patients

Objective: To examine concentration of Paraoxonase 1 enzymes across both Sudanese patients suffering from Type-I and Type-II diabetes. Methods: This was a cross-sectional study done in Khartoum/Sudan during the period from June 24th 2018 to August 23, 2018. One hundred seven diabetic patients (40 T1DM and 67 T2DM) compared with 45 healthy people from both genders. Biochemical parameters include PON1, FBG, HbA1C, and lipids were done and compared between study groups. Results: PON1 was reduced in patients than controls (P < 0.01), in addition PON1 was lower in T1DM than T2DM (P < 0.01), moreover, FBG, HbA1c and lipids was higher in diabetes than controls (P < 0.05). PON1 inversely correlated with LDL and apo B in T1DM (P < 0.01) and T2DM (P < 0.05), in addition PON1 correlated with HDL and apo A1 in T1DM (P < 0.01), inversely correlated with LDL in T2DM (P < 0.05) and with apo A1 in T2DM (P < 0.01). Moreover, PON1 inversely correlated with diabetes duration in T1DM (P < 0.01) and T2DM (P < 0.05). Conclusion: Sudanese T1DM and T2DM have a lower PON1 concentration than healthy subjects, T1DM have lower level of PON1 than T2DM. PON1 was inversely correlated with bad lipids and duration of diabetes, but it has positive correlation with good lipids.
Upper lobe preservation is not a challenge.

We have particularly appreciated the interesting letter from Cohen and colleagues (1) with their comments about our recent paper (2). They underline the importance of the use of lung-sparing operations for the treatment of NSCLC in order to avoid pneumonectomy. In particular, the latter authors confirm our suggestion that even a particular and challenging-considered operation such as lower sleeve lobectomy can provide good short and long term results (3-6). In our study (2), we stressed the aspect that left lower sleeve lobectomy and right lower bilobectomy should have been considered as a peculiar subset among sleeve resections in order to better investigate the outcome after this kind of reconstructive operations that, up to our paper, were usually included as very small number in wider series of bronchial and bronchovascular reconstruction patients.
A 5 ∼14GHz Wideband LNA using 0.13μm SiGe BiCMOS Technology

A Wideband low-noise amplifier (LNA) designed and implemented in 0.13 μm SiGe BiCMOS technology is presented in this paper. The inductive peaking technology is adopted to expand the bandwidth, the resistance negative feedback technology and the emitter degeneration inductive technology are adopted to improve the flatness of gain and input matching. This LNA achieves a flat gain of 10.7∼ 12.9 dB in the frequency range of $5\sim 14$ GHz. The noise figure $(NF)$ of the LNA is 3.5∼ 6.1 dB across the band. The input return losses (S11) of the LNA are better than -10 dB. The LNA dissipates 9.4mA with a 3.3 V supply.

The relationship between sexual activity and sexual function in breast and gynecologic cancer patients during adjuvant chemotherapy

Sexual problems are associated with greater depression, body change stress, and worse mental health quality-of-life in women who have survived cancer (Levin, Carpenter, Brothers, et al., 2010). Despite a number of studies of sexual activity and function in survivors of cancer, little is known about the natural course of resumption and maintenance of sexual activity following cancer diagnosis and treatment. This project tests the hypothesis that the presence of sexual activity during treatment will predict better sexual function and satisfaction scores at 4 months post treatment initiation when controlling for demographic, disease, psychosocial, and baseline sexual function. Patients (N=79) undergoing adjuvant chemotherapy completed questionnaires prior to, throughout, and 4-months after beginning treatment. In regression analyses, sexual activity predicted desire and arousal at 4 months, however higher satisfaction scores was not associated with sexual activity during treatment. Analyses predicting orgasm did not converge and therefore results were uninterpretable. The relationship between sexual activity and sexual satisfaction is complex and highly personal and more research is needed to understand better predictors of satisfaction. Results suggest that encouraging sexual activity may protect against loss in sexual function during adjuvant therapy. Providers are encouraged to have discussions with patients about their sexual lives alongside other quality-of-life concerns and to offer resources, if needed.

Unity power factor buck-boost LED driver for wide range of input voltage application

LED lighting sources have been used in several applications than established lighting sources due to their high luminous efficiency, environmental friendly, long life, compact size, and not affected by cold temperature. This paper deals with the design of buck-boost LED driver for wide input voltage applications. The proposed LED driver is a combination of uncontrolled rectifier followed by buck-boost converter. This converter is appropriate for wide input voltage applications from 85 Vac – 265 Vac. Over the line range, this topology accomplishes less total harmonic distortion (THD) and good power factor (PF). Average current control scheme is worn to accomplish improved power factor (PF) with low harmonics of line current. Simulation of buck-boost converter with LED load has been developed using PSIM software for 33.67 W. Load has modelled by connecting 13 LEDs in series by supplying 3.7 V & 0.7 A for each LED. For the proposed LED driver, parameter like power factor (PF) and total harmonic distortion (THD) of source current are assessed, it shows the power factor and THD of source current is very low and satisfies the IEC-61000-3-2 class C limits.
Cytomegalovirus Pneumonia in a Patient with Ankylosing Spondylitis: Case Report

Nowadays, biological agents such as anti-tumor necrosis factor alpha (anti-TNFα) drugs are used in the treatment of many chronic inflammatory diseases, particularly in those cases that do not respond to conventional treatments. However, infrequently, opportunistic infections such as bacterial, viral, fungal and parasitic infections may develop in patients treated with anti-TNF therapy, and physicians should be cautious in terms of increased risk of infection when using these agents. In this case report, we present a case of bilateral Cytomegalovirus (CMV) pneumonia in an adalimumab treated patient due to ankylosing spondylitis.
Use of antibiotics in Pediatric Dentistry: Not a child's play

Antibiotics are commonly used in dentistry for prophylactic as well as for therapeutic purposes. Most often antibiotics are used in unwarranted situations, which may give rise to resistant bacterial strains. Dentists want to make their patients well and to prevent unpleasant complications. These desires, coupled with the belief that many oral problems are infectious, stimulate the prescribing of antibiotics. Good knowledge about the indications of antibiotics is the need of the hour in prescribing antibiotics for dental conditions.

Interest of the six-minute walk test in the functional assessment of former pulmonary tuberculosis patients

Introduction. La tuberculose pulmonaire (TP) peut être pourvoyeuse de nombreuses séquelles souvent très handicapantes. Le but de ce travail était d’évaluer la tolérance à l’effort sous-maximal chez les anciens patients tuberculeux bactériologiquement confirmés, traités et déclarés guéris. Patients et méthode. Il s’est agi d’une étude transversale, les données ont été recueillies auprès des tuberculeux pulmonaires traités et déclarés guéris, à Lomé au Togo. Le test de marche de 6 minutes (TM6) a servi pour l’évaluation de la tolérance à l’effort sous-maximal et la spirométrie pour la détection des troubles ventilatoires (TV). Résultats. Un total de 113 patients a été inclus. La moyenne d’âge était de 33,95 ± 10,3 ans. Les hommes représentaient 69,9% de l’effectif. La distance moyenne parcourue au TM6 était de 635,55 ± 89,38 mètres avec des extrêmes de 441 et 849 mètres. Une proportion de 15% de nos patients avait parcouru une distance inférieure à la normale. On notait une association statistiquement significative entre le sexe féminin (p=0,005), le délai diagnostique (p=0,006) et les distances parcourues anormales. Par ailleurs, 67,3% des patients avaient un TV à la spirométrie, dominé par le syndrome restrictif (81,58%). Comparée à la spirométrie, le TM6 était sensible dans 78,95% des cas et spécifique dans 2,7%. Conclusion. La TP peut altérer significativement la fonction respiratoire des patients. Le TM6 peut constituer un instrument pour l’évaluation fonctionnelle des séquelles de TP.
Statements for Factual Question Generation

We address the problem of automatically generating concise factual questions from linguistically complex sentences in reading ma- terials. We discuss semantic and pragmatic issues that appear in com- plex sentences, and then we present an algorithm for extracting simpli- ed sentences from appositives, subordinate clauses, and other construc- tions. We conjecture that our method is useful as a preliminary step in a larger question generation process. Experimental results indicate that our method is more suitable for factual question generation applications than an alternative text compression algorithm.
An Advertisement Effect Simulator for Single Source Data and Its Experimental Evaluation

In the past, advertisements commercial advertisements in TV, Newspapers and Radio broadcasts were very common in Japan and most other countries in the world. Meanwhile, the contact situation to the media has been changing due to recent changes in lifestyles and the spread of smartphones and tablet-type devices worldwide. Therefore, when a company would like to announce their own product, cross media advertisement has become important. However, when announcing products, it is quite costly to advertise on various media. Hence, there are some problems how should company decide, what method of advertisement is the best. In this research, based on the single source data, Nomura Research Institute Ltd. investigates and provides, we create a simulator to estimate advertisement effect in each media. This simulation is based on data. Therefore, the precision of the simulation is affected by the number of data. The objective of this research is to find a relation between the number of data and the precision of the advertising effectiveness. For this purpose, we conducted experiments to observe changes in advertisement effectiveness when changing the number of consumers using a simulator, and the results are summarized.
