Determining Statistical Pattern on the Drug Related Killing in Philippines Using ARIMA and Poisson Techniques

A univariate time series technique was conducted to determine statistical pattern on killings of drug suspects in Philippines from May 19 to July 7, 2016. The technique reveal a moving average of order 2, MA(2) with a positive coefficient suggestive that value of outcome variable tend to increase, on the average, than the recent value of This means that drug related killings will tend to be higher than the most current rate; and killings is seen to increase as weekend comes. Poisson regression indicated an average of 13 deaths on a Sunday; only 2 on average on a Monday; odds of survival increases as well as weekend comes. Finally, the forecast model and the simulation are limited by the data used. Structure of the univariate series may change as additional data are added; this is also true for the forecasted average occurrence.
Polypharmacy and effects of apixaban versus warfarin in patients with atrial fibrillation: post hoc analysis of the ARISTOTLE trial
Venue: British Medical Journal

To determine whether the treatment effect of apixaban versus warfarin differs with increasing numbers of concomitant drugs used by patients with atrial fibrillation.  Post hoc analysis performed in 2015 of results from ARISTOTLE (apixaban for reduction in stroke and other thromboembolic events in atrial fibrillation) a multicentre, double blind, double dummy trial that started in 2006 and ended in 2011.  201 ARISTOTLE trial participants.  In the ARISTOTLE trial, patients were randomised to either 5 mg apixaban twice daily (n=9120) or warfarin (target international normalised ratio range 2.0 3.0; n=9081) In the post hoc analysis, patients were divided into groups according to the number of concomitant drug treatments used at baseline (0 5, 6 8, =9 drugs) with a median follow up of 1.8 years.  Clinical outcomes and treatment effects of apixaban versus warfarin (adjusted for age, sex, and country) Results Each patient used a median of six drugs (interquartile range 5 9) polypharmacy =5 drugs) was seen in 13 932 (76.5% patients. Greater numbers of concomitant drugs were used in older patients, women, and patients in the United States. The number of comorbidities increased across groups of increasing numbers of drugs (0 5, 6 8, =9 drugs) as did the proportions of patients treated with drugs that interact with warfarin or apixaban. Mortality also rose significantly with the number of drug treatments (P<0.001) as did rates of stroke or systemic embolism (1.29, 1.48, and 1.57 per 100 patient years, for 0 5, 6 8, and =9 drugs, respectively) and major bleeding (1.91, 2.46, and 3.88 per 100 patient years, respectively) Relative risk reductions in stroke or systemic embolism for apixaban versus warfarin were consistent, regardless of the number of concomitant drugs (Pinteraction=0.82) A smaller reduction in major bleeding was seen with apixaban versus warfarin with increasing numbers of concomitant drugs (Pinteraction=0.017) Patients with interacting (potentiating) drugs for warfarin or apixaban had similar outcomes and consistent treatment effects of apixaban versus warfarin.  In the ARISTOTLE trial, three quarters of patients had polypharmacy; this subgroup had an increased comorbidity, more interacting drugs, increased mortality, and higher rates of thromboembolic and bleeding complications. In terms of a potential differential response to anticoagulation therapy in patients with atrial fibrillation and polypharmacy, apixaban was more effective than warfarin, and is at least just as safe.
Le Manuel pratique de la methode Montessori

A l'heure ou les guides pratiques sur la methode Montessori se multiplient, voici celui que Maria Montessori a elle meme concu pour entrer dans les familles ecrit en espagnol en 1939 (etayant une premiere version de 1914 en anglais) Inedite en francais, cette version historique a neanmoins garde toute son actualite. Dans ce manuel, qui n'est pas seulement pratique, Maria Montessori presente aussi la philosophie de sa pedagogie en rappelant son objectif final servir la Paix. Elle insistait en effet sur le fait que l'education etait la meilleure arme pour la Paix, et qu'il fallait, pour l'atteindre, considerer l'enfant comme le guide de son education. Qui mieux que lui meme sait ce qui est bon pour son propre developpement Originalite de ce manuel il est le seul illustre par des photos personnelles de Maria Montessori. La traductrice s'est efforcee de reproduire en couleur ces photos soigneusement choisies. La mise en parallele des cliches historiques en noir et blanc et des photos contemporaines montre bien qu'en depit du siecle qui s'est ecoule depuis l'ouverture de la premiere Maison des Enfants et malgre toutes les evolutions de la methode qui n'est ni figee ni passeiste, l'essentiel est reste identique.
Systematic review of 3D mammography for breast cancer screening.
Venue: Breast

This review investigated the relative performance of digital breast tomosynthesis (DBT) (alone or with full field digital mammography (FFDM) or synthetic digital mammography) compared with FFDM alone for detecting breast cancer lesions in asymptomatic women. A systematic review was carried out according to systematic reviewing principles provided in the Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy. A protocol was developed a priori.  Searches were undertaken in October 2014. Following selection, five studies were eligible. Higher cancer detection rates were observed when comparing DBT FFDM with FFDM in two European studies: the summary difference per 1000 screens was 2.43 (95% CI: 1.8 to 3.1) Both European studies found lower false positive rates for individual readers. One found a lower recall rate based on conditional recall. The second study was not designed to compare post arbitration recall rates between FFDM and DBT FFDM. One European study presented data on interval cancer rates; sensitivity and specificity for DBT FFDM were both higher compared to FFDM. One large multicentre US study showed a higher cancer detection rate for DBT FFDM, while two smaller US studies did not find statistically significant differences. Reductions in recall and false positive rates were observed in the US studies in favour of DBT FFDM. In comparison to FFDM, DBT, as an adjunct to FFDM, has a higher cancer detection rate, increasing the effectiveness of breast cancer screening. Additional benefits of DBT may also include reduced recalls and, consequently, reduced costs and distress caused to women who would have been recalled.
Comparative assessment of onabotulinumtoxinA and mirabegron for overactive bladder: an indirect treatment comparison
Venue: BMJ Open

Context  and mirabegron have recently gained marketing authorisation to treat symptoms of overactive bladder (OAB)  To evaluate the relative efficacy of mirabegron and onabotulinumtoxinA in patients with idiopathic OAB. Design Network meta analysis.  A search of 9 electronic databases, review documents, guidelines and websites.  Randomised trials comparing any licensed dose of onabotulinumtoxinA or mirabegron with each other, anticholinergic drugs or placebo were eligible (19 randomised trials were identified) 1 reviewer extracted data from the studies and a second reviewer checked the data. Candidate trials were assessed for similarity and networks were developed for each outcome. Bayesian network meta analysis was conducted using both fixed effects and random effects models. When there were differences in mean baseline values between mirabegron and onabotulinumtoxinA trials they were adjusted for using network meta regression (NMR) Results No studies directly comparing onabotulinumtoxinA to mirabegron were identified. A network was created for each of the 7 outcomes, with 3 9 studies included in each individual network. The trials included in the networks were broadly similar. Patients in the onabotulinumtoxinA trials had more urinary incontinence and urgency episodes at baseline than patients in the mirabegron trials and these differences were adjusted for using NMR. Both onabotulinumtoxinA and mirabegron were more efficacious than placebo at reducing the frequency of urinary incontinence, urgency, urination and nocturia. OnabotulinumtoxinA was more efficacious than mirabegron (50 and 25 mg) in completely resolving daily episodes of urinary incontinence and urgency and in reducing the frequency of urinary incontinence, urgency and urination. NMR supported the results of the network meta analysis.  In the absence of head to head trials comparing onabotulinumtoxinA to mirabegron, this indirect comparison indicates that onabotulinumtoxinA may be superior to mirabegron in improving symptoms of urinary incontinence, urgency and urinary frequency in patients with idiopathic OAB.

Novel microinjector for carrying bone substitutes for bone regeneration in periodontal diseases.
Venue: Journal of the Formosan Medical Association Taiwan yi zhi

Traditionally, guide bone regeneration (GBR) was a widely used method for repairing bone lost from periodontal disease. There were some disadvantages associated with the GBR method, such as the need for a stable barrier membrane and a new creative cavity during the surgical process. To address these disadvantages, the purpose of this study was to evaluate a novel microinjector developed for dental applications. The microinjector was designed to carry bone graft substitutes to restore bone defects for bone regeneration in periodontal diseases. The device would be used to replace the GBR method.  In this study, the injected force and ejected volume of substitutes (including air, water, and ethanol) were defined by Hooke's law (n 3) The optimal particle size of bone graft substitutes was determined by measuring the recycle ratio of bone graft substitutes from the microinjector (n 3) Furthermore, a novel agarose gel model was used to evaluate the feasibility of the microinjector.  The current study found that the injected force was less than 0.4 N for obtaining the ejected volume of approximately 2 mL, and when the particle size of tricalcium phosphate (TCP) was smaller than 0.5 mm, 80% TCP could be ejected from the microinjector. Furthermore, by using an agarose model to simulate the periodontal soft tissue, it was also found that bone graft substitutes could be easily injected into the gel.  The results confirmed the feasibility of this novel microinjector for dental applications to carry bone graft substitutes for the restoration of bone defects of periodontal disease.
Apical/Retrograde Periimplantitis/Implant Periapical Lesion: Etiology, Risk Factors, and Treatment Options A Systematic Review
Venue: Implant dentistry

To review the literature on retrograde periimplantitis symptoms, risk factors, and treatment methods and to propose a decision making tree of retrograde periimplantitis management. An electronic literature search was conducted on the MEDLINE and EMBASE databases for articles published between 1990 and 2015. Clinical human studies in the English language were included. The search resulted in 44 case reports published by 27 authors. The average time of the diagnosis of the pathology was found to be 26.07 weeks after implant placement (SD 39.7) Fistula formation was found to be the most common clinical symptom, statistically significantly more often occurring in the maxilla (P 0.04) A negative correlation was found between pain and the adjacent tooth with incomplete endodontic treatment/endodontic pathology (r 0.4; P 0.009) and a positive correlation between the later risk factor and implant removal (r 0.3; P 0.028) Regenerative treatment (45.2% of the cases) or implant removal (35.7% of the cases) was the most common treatment techniques used. A decision making tree of retrograde periimplantitis management is suggested. The etiology of retrograde periimplantitis is most often infectious. A decision making tree aimed at managing patients with retrograde periimplantitis according to the possible etiology and symptoms of the disease can be a useful tool in the treatment of the pathology.
Range Based Localization Algorithm for Next Generation Wireless Networks Using Radical Centers
Venue: IEEE Access

Localization is an important issue in next generation wireless networks (NGWNs) such as 5G cellular networks, IEEE 802.11ax WiFi networks, and wireless ad hoc sensor network (WASNs) This paper proposes a 3 D localization algorithm for NGWNs by utilizing the concept of radical centers from analytic geometry, and takes WASNs as an example. Assume that an unknown node can measure its distances to four or more anchor nodes (reference nodes) By picking four distance measurements to four anchor nodes, a radical center is computed. Through analytic formulation, the radical center is shown to be able to be treated as an estimation of the unknown node location. Since every four distance measurements generates one radical center (in 3 D space) to further improve and fuse these estimations, effective filtering mechanisms are proposed to filter out the improper estimations. Afterward, the remaining radical centers are averaged, and the solution is the final estimation of the unknown node location. The location errors of the proposed algorithm and the conventional minimum mean square error (MMSE) method were analytically compared. It was shown that the proposed algorithm outperforms the conventional MMSE method both in accuracy and efficiency. Extensive computer simulations were carried out and the results verified the advantage of the proposed location algorithm over the MMSE approach.
The internal structure of poly(methyl methacrylate) latexes in nonpolar solvents.
Venue: Journal of colloid and interface science

Poly(methyl methacrylate) (PMMA) latexes in nonpolar solvents are an excellent model system to understand phenomena in low dielectric media, and understanding their internal structure is critical to characterizing their performance in both fundamental studies of colloidal interactions and in potential industrial applications. Both the PMMA cores and the poly(12 hydroxystearic acid) (PHSA) shells of the latexes are known to be penetrable by solvent and small molecules, but the relevance of this for the properties of these particles is unknown.  These particles can be prepared in a broad range of sizes, and two PMMA latexes dispersed in n dodecane (76 and 685nm in diameter) were studied using techniques appropriate to their size. Small angle scattering (using both neutrons and X rays) was used to study the small latexes, and analytical centrifugation was used to study the large latexes. These studies enabled the calculation of the core densities and the amount of solvent in the stabilizer shells for both latexes. Both have consequences on interpreting measurements using these latexes.  The PHSA shells are highly solvated ~85% solvent by volume) as expected for effective steric stabilizers. However, the PHSA chains do contribute to the intensity of neutron scattering measurements on concentrated dispersions and cannot be ignored. The PMMA cores have a slightly lower density than PMMA homopolymer, which shows that only a small free volume is required to allow small molecules to penetrate into the cores. Interestingly, the observations are essentially the same, regardless of the size of the particle; these are general features of these polymer latexes. Despite the latexes being used as a model physical system, the internal chemical structure is complex and must be fully considered when characterizing them.
Improving Fully Convolution Network for Semantic Segmentation
Venue: ArXiv

Fully Convolution Networks (FCN) have achieved great success in dense prediction tasks including semantic segmentation. In this paper, we start from discussing FCN by understanding its architecture limitations in building a strong segmentation network. Next, we present our Improved Fully Convolution Network (IFCN) In contrast to FCN, IFCN introduces a context network that progressively expands the receptive fields of feature maps. In addition, dense skip connections are added so that the context network can be effectively optimized. More importantly, these dense skip connections enable IFCN to fuse rich scale context to make reliable predictions. Empirically, those architecture modifications are proven to be significant to enhance the segmentation performance. Without engaging any contextual post processing, IFCN significantly advances the state of the arts on ADE20K (ImageNet scene parsing) Pascal Context, Pascal VOC 2012 and SUN RGBD segmentation datasets.
ScribbleSup: Scribble Supervised Convolutional Networks for Semantic Segmentation
Venue: 2016 IEEE Conference on Computer Vision and Pattern Recognition (CVPR)

Large scale data is of crucial importance for learning semantic segmentation models, but annotating per pixel masks is a tedious and inefficient procedure. We note that for the topic of interactive image segmentation, scribbles are very widely used in academic research and commercial software, and are recognized as one of the most userfriendly ways of interacting. In this paper, we propose to use scribbles to annotate images, and develop an algorithm to train convolutional networks for semantic segmentation supervised by scribbles. Our algorithm is based on a graphical model that jointly propagates information from scribbles to unmarked pixels and learns network parameters. We present competitive object semantic segmentation results on the PASCAL VOC dataset by using scribbles as annotations. Scribbles are also favored for annotating stuff (e.g. water, sky, grass) that has no well defined shape, and our method shows excellent results on the PASCALCONTEXT dataset thanks to extra inexpensive scribble annotations. Our scribble annotations on PASCAL VOC are available at http:/research.microsoft.com/en us/um/ people/jifdai/downloads/scribble_sup.
Fully Convolutional Networks for Semantic Segmentation of Fluorescence Microscopies

We experiment with fully convolutional neural networks "FCNs" that discard the traditional fully connected layers of a ConvNet, in order to produce a pixel wise class prediction and loss. While our fully convolutional network is ultimately unable to perform accurate semantic segmentation of dendritic spine images, we demonstrate that a model, consisting of a joint sliding window regionproposal network and SVM classifier, is capable of accurately predict the location of dendritic spines in microscopies of stained mouse neurons. Our model holds the potential to change the face of one sector of neuroscience research by replacing laborious hand annotation of dendritic spine structures with automatic detection.

HyperspaceFlow: A System Level Design Methodology for Smart Space
Venue: IEEE Transactions on Emerging Topics in Computing

Smart space technology gains intensive attentions of the worldwide due to the advancement of pervasive computing. However, the design of smart space is inherently complex as it resides in highly varying environment with multiple devices, also the power consumption, cost, and user preference are usually ignored by designers, resulting in huge design cost, high power dissipation, and unsatisfactory user experience. In this paper, we present a system level design methodology for smart space, which is able to refine the function specification of smart space into underlying implementations leveraging an intermediate representation model HyperspaceFlow. The tasks in smart space are deposited into distributed execution platforms, and a network is automatically synthesized to satisfy their needs of communication at given QoS constraints. Meanwhile, the proposed design methodology is able to offer relatively satisfactory cost, power consumption, and user preference of the design solution at given constraints. At last, a home health care case is used to elucidate our design methodology, and the simulation results demonstrate the effectiveness and feasibility of our methodology.
