A comparative study of relational database and key-value database for big data applications

Nowadays, Demands of web scale are in increasing and growing rapidly. Mobile applications, web technologies, social media always generates unstructured data that had lead to the advent of various NoSQL databases. Therefore, Big data applications are necessary to have an efficient technology to collect these data. However, a relational database is the traditional database that always uses in many applications and still has more valuable to play a significant role in the current information system. The main characteristics of NoSQL databases are schema-free, no relationship, no need to join as a relational database. The business organization expects that NoSQL database has better performance than a relational database. In This paper, we aim to compare the performance of Redis, which is a key-value database, one kind of NoSQL database, and MariaDB, which is a popular relational database. We designed a set of experiments with a large amount of data and compared the efficiency of the insert, update, delete and select transactions from various aspects on the same dataset. We measure the processing time of each transaction to evaluate the comparison. The results have shown that Redis has better runtime performance for insert, delete, update transaction under a specific condition or complex queries. MariaDB still is good for some conditions especially when we have a small data. Our study can help to choose a database that will be suitable for the real world applications because relational databases and NoSQL databases have different strengths and weakness.

Ebola virus disease: emergence, outbreak and future directions.

BACKGROUND The West African Ebola crisis of 2013-15 is the largest outbreak since Ebola was first identified; Ebola has high case fatality. SOURCES OF DATA Pubmed with terms 'Ebola' and 'EVD' from January 1976 to June 2015. Public domain material. AREAS OF AGREEMENT The emergence of Ebola virus, virology, clinical features and the major elements of the 2014 outbreak and the public health response. Ebola is only transmitted by direct contact with infected individuals (including dead bodies) and their body fluids. Methods of control in hospitals and burials, and protection of healthcare workers are well established if difficult to achieve. AREAS OF CONTENTION There remains uncertainty surrounding specific public health interventions and novel therapies (including vaccines). How best to reduce transmission in the community during major outbreaks remains unclear. FUTURE DIRECTIONS The potential of vaccine and therapeutic candidates in the event of another outbreak on this scale. SEARCH STRATEGY We searched all entries on the MedLine database/PubMed from 1976-2015 with the MeSH terms 'ebola', 'EVD', 'haemorrhagic fever'. We also reviewed publically available information via institutional websites from Governmental, NGOs and news organizations pertaining to the above search terms.
The Evolution of Empty Flowers Revisited

The evolution of plants that provide no form of reward for their pollinators is puzzling because they receive low numbers of pollinator visits and so have low reproductive success. To predict the evolutionary dynamics of empty morphs within a plant population, we modeled different foraging strategies that pollinators could use to avoid them. We predicted that the optimal strategy was to visit empty inflorescences randomly when these were infrequent but to use strategies such as visiting fewer flowers per inflorescence to avoid wasting time on them. As the frequencies of empty inflorescences increased, discriminating directly against empty morphs was more likely to be an optimal strategy than was avoiding the species altogether and switching to an alternative one. An experimental test of this model using artificial inflorescences showed that bumblebees used a variety of strategies to minimize time wasted on empty inflorescences. They showed weak discrimination against empty inflorescences but switched to an alternative type of inflorescence as the frequency of empty inflorescences increased. We predicted that empty morphs would be at a visitation rate disadvantage even when at low frequencies in a plant population. Differences in outcrossing rates, or male function, may explain how rewardlessness spreads in a plant population.
Anaplastic seminoma

Eight patients with the diagnosis of anaplastic seminoma of the testicle were treated during the megavoltage era from January 1959 to January 1976. Two patients with Stage I disease and one patient with Stage IV disease have died from their malignancy. By contrast, 57 patients with typical seminoma were treated during the same interval and with the same treatment methods. However, only two patients with typical seminoma have died. One of these patients had Stage II disease and one had Stage IV disease. There were no deaths among patients with Stage I typical seminoma. These results suggest that anaplastic seminoma has a poorer prognosis than typical seminoma even when the diseeses are compared stage for stage. Implications for therapy are discussed.

A population and harvest intensity estimate for Sooty Shearwater,Puflinus griseus, on Taukihepa (Big South Cape), New Zealand

We estimated the total number of burrow entrances, chicks and total population size of the Sooty Shearwater, Puffinusgriseus, colony on Taukihepa (Big South Cape), the largest of the 36 Titi Islands where Titi (Sooty Shcarwater chicks) are harvested. Between 1999 and 2005 we surveyed six manu (family birded areas) as well as a colony in the interior forested region on the island, measuring entrance density and burrow occupancy and habitat variables, as well as recording birders' harvest intensity. We found little support for any relationship between habitat variables and entrance density on the surveyed manu. Therefore we used a detailed aerial image to map areas and extrapolate these estimates to island totals and a simple population model, incorporating known demographic parameters to calculate the total population size. We estimated that the island contains 1.67 million (95% CI: 1.47-1.88) burrow entrances and 1.12 million (0.959-1.28) breeding pairs, equating to a total of 5.31 million (95% CI: 3.98-6.77) juveniles, pre-breeders and adults associated with the island. Assuming the harvest intensity on the surveyed manu 0.18% (0.16-0.21) was similar elsewhere on the unsurveyed but harvested region of the island, we estimated that ofthe 807000 (712000-901 000) fledging chicks on the island, 137000 (105000-173000) are harvested each year. These findings highlight the importance of the island both in terms of total Sooty Shearwater population in New Zealand and to the Rakiura Maori who harvest the Titi.

On-chip dual-arm microrobot driven by permanent magnets for high speed cell enucleation

This paper presents innovative driving method for the magnetically driven microtool (MMT) which is actuated in a microfluidic chip by permanent magnets on the XY stage. A piezoelectric ceramic is applied to induce ultrasonic vibration to the microfluidic chip and the high-frequency vibration reduces the effective friction on the MMT significantly. As a result, we achieved 1.1 micrometer positioning accuracy of the MMT, which is 100 times higher accuracy than without vibration. The enucleation process has been conducted inside the microfluidic chip by this precisely controlled MMT and we achieved to remove nucleus from swine oocytes in high speed.
Estrogen‐ and androgen‐responsive growth of human ovarian adenocarcinoma heterotransplanted into nude mice

A new line of human serous cystadenocarcinoma of the ovary, designated OVA‐5, has been established in athymic nude mice. A strong correlation was noted between tumor volume and plasma CA 125 levels in mice bearing OVA‐5 tumor. Growth of the OVA‐5 tumor in castrated male nude mice was accelerated by s.c. administration of estradiol‐17β and 5α‐dihydrotestosterone but not by progesterone. Estradiol‐17β and 5α‐dihydrotestosterone also accelerated the growth of the OVA‐5 tumor heterotransplanted into sialoadenectomized castrated male nude mice. No remarkable change was observed in the histological appearances of the tumors between control groups and hormone‐treated groups. Receptor assays revealed that the OVA‐5 tumor had both estrogen and androgen receptors. Growth of the OVA‐5 tumor is thus responsive to estrogen and androgen.
Association Between Physical and Motor Development in Childhood: A Longitudinal Study of Japanese Twins

Length and weight in infancy are associated with neurodevelopment, but less is known about growth in other anthropometric measures. In this study we analyzed how the development in length, weight, head circumference, and chest circumference over infancy is associated with motor development in early childhood, using a twin study design. Information on physical development over infancy and the age at achievement of eight developmental milestones over early childhood was collected for 370 Japanese twin pairs. Linear mixed models were used to analyze how physical development is associated with motor development between individual twins, as well as within twin pairs, adjusting the results for shared maternal and postnatal environmental factors. Delayed motor development was associated with smaller body size over infancy, and we also found some suggestive evidence that it was associated with catch-up growth as well. When studying the associations within twin pairs discordant for motor development, similar associations were found. However, chest circumference showed the most robust association within discordant twin pairs. Smaller body size and rapid catch-up growth are associated with delayed motor development. When studying these associations within twin pairs and thus adjusting the results for gestational age as well as many other maternal and postnatal environmental factors, chest circumference showed the most robust association. Chest circumference, rarely used in developed countries, can offer additional information on prenatal conditions relevant for further motor development not achieved by more traditional anthropometric measures.
A preliminary investigation of the utility of the “Behavior Support Plan Quality Evaluation Guide II” for use in Australia

Abstract Background The quality of behaviour support plans (BSPs) can be an important influence on the quality of the support provided to people with disability who show challenging behaviours. The Behavior Support Plan Quality Evaluation Guide II (BSP-QE II) is one tool that may be useful in assessing the quality of behaviour support plans. It has previously been used to assess BSPs to support children in schools in the USA. In this preliminary study, we examined the utility of the BSP-QE II for assessing behaviour support plans designed for adults with an intellectual disability in community support services in Australia. Method Experienced practitioners were surveyed concerning the relevance of BSP-QE II components to the evaluation of BSPs in Australia, and an audit was conducted of randomly selected BSPs submitted as a statutory requirement to the Office of the Senior Practitioner. Results The BSP-QE II showed evidence of acceptable construct validity and interrater reliability. There was evidence of a need for substantial improvement in the quality of BSPs, consistent with previous findings conducted using other audit tools. Conclusions The findings support the utility of the BSP-QE II, to inform and evaluate service planning in supporting adults with intellectual disability who show challenging behaviour.
The evolution of worry after breast cancer risk assessment: 6‐year follow‐up of the TRACE study cohort

Objectives: There is little evidence regarding the long‐term psychological implications of breast cancer risk assessment for women at moderate genetic risk. A follow‐up study of a trial cohort was conducted to evaluate psychological outcomes and their predictors at 6‐year follow‐up. A further aim was to examine threshold scores for high cancer worry.
Material-specific transfer function model and SNR in CT

This study presents an analytical model for the edge spread function (ESF) of a clinical CT system that allows reliable fits of noisy ESF data. The model was used for the calculation of the material-specific transfer function TF and an estimation of the signal transfer and the signal-to-noise ratio (SNR) in 2D. Images of the Catphan phantom were acquired with a clinical Siemens Somatom Sensation Cardiac 64 CT scanner combining four different x-ray tube outputs (40, 150, 250 and 350 mAs) with four different reconstruction filters, which covered the range from very smooth (B10s) to very sharp (B70s). The images of the high- and mid-contrast cylinders of the phantom’s ‘Geometry and Sensitometry’ module (air, Teflon, Delrin and PMP) were used to sample material-specific ESF curves. The ESF curves were fitted with the analytical model we developed based on a linear combination of Boltzmann and Gaussian functions. The analytical model of the ESF was used to obtain the Fourier-based material-specific transfer function TF, as well as the spatial-domain point spread function (PSF). TF was subsequently used to estimate the signal transfer, which was compared to the actual reconstructed image of a 3.0 mm diameter Teflon pin. The noise power spectrum (NPS) was calculated from images of a uniform water phantom under the same technique parameters. The task-specific SNR was calculated for all technique parameters from the model-based TF, the measured NPS and simulated 3 mm diameter disc signals modeling the aforementioned materials. Bootstrapping was performed to estimate the standard deviation of the TF and the SNR. The analytical model we developed accurately captured the features of the CT ESF data. The coefficient of determination R2, a metric that describes the goodness of the fit, had a median value of 0.9995, and decreased for low tube output, low contrast and the sharp reconstruction filter. Our analysis showed that ESF, PSF and TF depended not only on the reconstruction filter, but also on the tube output and the material of the cylinders. For B40s and B70s, the TF of Delrin was significantly higher than the TF of other materials in the frequency range of 0.4–0.9 mm−1. The estimated signal transfer agreed well with the actual reconstructed image of the Teflon pin. For the technique parameters we used the SNR values ranged between [64, 320], [64, 281], [37, 137] and [33, 117] for air, Teflon, Delrin and PMP respectively. While for high-contrast materials the smoothest reconstruction filter resulted in the highest SNR, for mid-contrast materials the standard filter gave the best results. The presented approach provides an accurate, analytical description of the material-specific ESF, PSF and TF as well as an estimate of the signal transfer. The transfer function TF together with the NPS and simulated signals allow the calculation of a task-specific SNR.
Racism and Illicit Drug Use Among African American Women

Though recent evidence indicates that rates of illicit drug use among African American women are now higher than the national average, little is known about the etiology of substance use in this population. In addition, the effects of racism and other cultural factors are understudied and may be unique among African American women. This cross-sectional study explores risk and protective factors for drug use among 204 African American women. More specifically, associations between racism experiences and drug use are investigated in the context of potential moderating influences (i.e., psychosocial resources, social safety net variables, and cultural identity and practices). Findings suggest that racism is associated with drug use, but that its effects diminish with age. In addition, results suggest that psychosocial resources, social safety net factors and culturally specific factors such as ethnic community membership and engagement in cultural practices afford African American women some protection against the detrimental effects of racism.
Evaluation of Antitumor Activity of Bark Extract of Magnolia grandiflora Linn. in vivo and in vitro

Antitumor activity of 50% ethanol bark extract of Magnolia grandiflora Linn. was evaluated against tumors induced in mice using dimethyl benzanthracene (DMBA) and 3-methyl cholanthrene (MC). The activity was assessed using the ability of the plant extract in reducing tumor weight, tumor volume and lung weight. The plant extract treated groups showed significant reduction in tumor weight, tumor volume and lung weight. The cytotoxic/cytostatic activity of the plant extract on human cancer cell line Bu25Tk־ cells was also evaluated using 3-(3,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Cells at proliferative phases were treated with the plant extracts and incubated for 48 hrs at 37oC, 5% carbon dioxide (CO2) and 100% relative humidity. After 48 hrs, MTT working solution was added to the culture, incubate for 4 hrs and centrifuged at 1700 rpm for 10 min. The supernatant was removed and dimethyl sulfoxide (DMSO) was added, thoroughly mixed and the absorbance was measured at 546 nm. The results of the present experiment indicate the ability of the plant extract in reducing the tumor weight and volume as well as lung weight in mice and growth of human cervical cancer cell Bu25Tk־ on a dose dependent manner.
Comparison of Local Wound Infiltration with Ropivacaine Alone or Ropivacaine Plus Dexmedetomidine for Postoperative Pain Relief after Lower Segment Cesarean Section

Context: Dexmedetomidine, α2-adrenergic agonist, when coadministered with local anesthetics, improves the speed of onset, duration of analgesia and decreases the dose of local anesthetic used. Aims: The aim of this study was to compare the efficacy of local subcutaneous wound infiltration of ropivacaine alone with ropivacaine plus dexmedetomidine for postoperative pain relief following lower segment cesarean section (LSCS). Subjects and Methods: The study was a prospective, randomized control, double-blind study. Sixty female patients belonging to physical status American Society of Anesthesiologists Grade I or II scheduled for LSCS under spinal anesthesia were randomly allocated into two groups of thirty patients each. Group A: local subcutaneous wound infiltration of 0.75% ropivacaine (3 mg/kg) diluted with normal saline to 40 ml. Group B: local subcutaneous wound infiltration of 0.75% ropivacaine (3 mg/kg) plus dexmedetomidine (1.5 μg/kg) of the body weight diluted with normal saline to 40 ml. Standard spinal anesthesia technique was used and LSCS was conducted. The allocated drug was administered by local subcutaneous wound infiltration before closure of the skin. In postoperative period, pain was assessed using visual analog scale (VAS) over a period of 24 h, time of giving first rescue analgesic consumption, mean analgesic consumption, patient satisfaction, and incidence of side effects in 24 h postoperative period was noted. Statistical Analysis Used: All observations were tabulated and statistically analyzed using Chi-square test and unpaired t-test. Results: A total number of patients requiring rescue analgesic, mean VAS each time rescue analgesic was given, and the mean analgesic required in 24 h postoperative period was lesser in Group B than in Group A. Conclusions: Dexmedetomidine added to ropivacaine for the surgical wound infiltration significantly reduces postoperative pain and rescue analgesic consumption in patients undergoing LSCS. No serious adverse effects were noted.
An Algorithm Guiding the Evaluation and Treatment of Acute Primary Patellar Dislocations

Primary patellar dislocation continues to be a common problem facing clinicians today. These injuries are associated with significant morbidity and a substantial recurrence rate. A myriad of operative and nonoperative options have been described to treat these injuries though the evidence-based literature is sparse. As a result, much controversy exists regarding the ideal management of the primary patellar dislocation. This article reviews the literature on this topic, from the initial examination and management to definitive treatment. Furthermore, an algorithm is presented to help the clinician approach and treat these patients.
Our Experience on Oncoplastic Breast Surgery: Clinical Report and Mini Review

Breast cancer presents a common form of cancer in women, associated with increased mortality, costs, and psychosocial problems. Breast conserving surgery became a serious alternative of radical mastectomy in early stages of breast cancer. This technique tends to have the same oncological results as radical mastectomy but with better cosmetic results. Several factors may have an impact of what surgical technique is preferred by the patients. Breast cancer staging, education level, rural or urban residence, and the relationship between the surgical team and the patient, are the most important factors that cam modify the surgical technique. Albanian population has some specific regarding residence, education level, and a great difident sense regarding physicians. Our trail through this retrospective descriptive study tends to present and explain the results in our population.
