Video Watermarking Scheme Based on Candidates I-frames for Copyright Protection
Authors: Ahuja Rakesh , Bedi Dr. Sarabjeet Singh 
Published: May 2017

<p>This paper focuses on moving picture expert group ( MPEG) based digital video watermarking scheme for copyright protection services. The present work implemented the video watermarking technique in which discrete cosine transform (DCT) intermediate frequency coefficients from instantaneous decoder refresh (IDR) frames are utilized. The subset of IDR frames as candidate frames are chosen to reduces the probability of temporal synchronization attacks to achieve better robustness and high visual perceptual quality. A secret key based cryptographic technique is used to enhance the security of embedded watermark. The proposed scheme embedded the watermark directly during the differential pulse code modulation (DPCM) process and extracting through decoding the entropy details. Three keys are required to extract the watermark whereas one of the key is used to stop the extraction process and the remaining two are used to display the watermark. The robustness is evaluated by testing spatial synchronization attacks, temporal synchronization attacks and re-encoding attacks. The present work calculates the simulation results that shows the watermarking scheme achieved high robustness against video processing attacks frequently occur in the real world and perceptibility also obtained without changing the motion vectors during the DPCM process of MPEG-2 encoding scheme.</p>

Authors: Hammood Al-jiz Khalid , Atinah Ahmad Noor , Subhi Fadhel Fadhel 
Published: May 2017

<p>Riccati matrix differential equation has long been known to be so difficult to solve analytically and/or numerically. In this connection, most of the recent studies are concerned with the derivation of the necessary conditions that ensure the existence of the solution. Therefore, in this paper, He’s Variational iteration method is used to derive the general form of the iterative approximate sequence of solutions and then proved the convergence of the obtained sequence of approximate solutions to the exact solution. This proof is based on using the mathematical induction to derive a general formula for the upper bound proved to be converge to zero under certain conditions. </p>
Genome-Wide Association Studies and Meta-Analyses for Congenital Heart Defects
Authors: Agopian A. J. , Goldmuntz Elizabeth , Hakonarson Hakon , Sewda Anshuman , Taylor Deanne , Mitchell Laura E. 
Published: May 2017

Background—
Maternal and inherited (ie, case) genetic factors likely contribute to the pathogenesis of congenital heart defects, but it is unclear whether individual common variants confer a large risk.

Methods and Results—

To evaluate the relationship between individual common maternal/inherited genotypes and risk for heart defects, we conducted genome-wide association studies in 5 cohorts. Three cohorts were recruited at the Children’s Hospital of Philadelphia: 670 conotruncal heart defect (CTD) case-parent trios, 317 left ventricular obstructive tract defect (LVOTD) case-parent trios, and 406 CTD cases (n=406) and 2976 pediatric controls. Two cohorts were recruited through the Pediatric Cardiac Genomics Consortium: 355 CTD trios and 192 LVOTD trios. We also conducted meta-analyses using the genome-wide association study results from the CTD cohorts, the LVOTD cohorts, and from the combined CTD and LVOTD cohorts. In the individual genome-wide association studies, several genome-wide significant associations (
P
≤5×10
−8
) were observed. In our meta-analyses, 1 genome-wide significant association was detected: the case genotype for rs72820264, an intragenetic single-nucleotide polymorphism associated with LVOTDs (
P
=2.1×10
−8
).

Conclusions—
We identified 1 novel candidate region associated with LVOTDs and report on several additional regions with suggestive evidence for association with CTD and LVOTD. These studies were constrained by the relatively small samples sizes and thus have limited power to detect small to moderate associations. Approaches that minimize the multiple testing burden (eg, gene or pathway based) may, therefore, be required to uncover common variants contributing to the risk of these relatively rare conditions.
Long-Term Efficacy and Safety of Everolimus-Eluting Bioresorbable Vascular Scaffolds Versus Everolimus-Eluting Metallic Stents
Authors: Mahmoud Ahmed N. , Barakat Amr F. , Elgendy Akram Y. , Schneibel Erik , Mentias Amgad , Abuzaid Ahmed , Elgendy Islam Y. 
Published: May 2017

Background—
Data regarding the long-term efficacy and safety of everolimus-eluting bioresorbable vascular scaffolds (BVS) compared with everolimus-eluting stents are limited. This meta-analysis aimed to compare the long-term outcomes with both devices.

Methods and Results—
Randomized trials reporting clinical outcomes beyond 1 year and comparing BVS with everolimus-eluting stents were included. Summary estimates risk ratios (RRs) were constructed. The primary efficacy outcome was target lesion failure, defined as cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization, and the primary safety outcome was definite or probable stent/scaffold thrombosis. Six trials with 5392 patients were included (mean follow-up, 25 months). BVS had a higher rate of target lesion failure (RR, 1.33; 95% confidence interval [CI], 1.11–1.58) driven by the higher rates of target vessel myocardial infarction (RR, 1.65; 95% CI, 1.26–2.17) and target lesion revascularization (RR, 1.39; 95% CI, 1.08–1.78). The risk of definite or probable stent/scaffold thrombosis (RR, 3.22; 95% CI, 1.89–5.49) and very late stent/scaffold thrombosis (>1 year; RR, 4.78; 95% CI, 1.66–13.8) was higher with BVS. The risk of cardiac and all-cause mortality was similar in both groups.

Conclusions—
Compared with everolimus-eluting stents, BVS is associated with increased risk of target lesion failure driven by the increased rates of target vessel myocardial infarction and ischemia-driven target lesion revascularization in these studies (mean follow-up, 25 months). The risk of definite or probable stent/scaffold thrombosis and very late stent/scaffold thrombosis seems to be higher with BVS. Further information from randomized trials is critical to evaluate clinical outcomes with BVS on complete resolution of the scaffold.

Published: May 2017

Background

Proprotein convertase subtilisin/kexin type 9 (PCSK9) circulating levels are significantly associated with an increased risk of cardiovascular events. This study aimed to evaluate the relationship between circulating levels of
PCSK
9 and arterial stiffness, an early instrumental biomarker of cardiovascular disease risk, in a large sample of overall healthy participants.

Methods and Results

From the historical cohort of the Brisighella Heart Study, after exclusion of active smokers, participants in secondary prevention for cardiovascular disease, and patients in treatment with statins or vasodilating agents, we selected 227 premenopausal women and 193 age‐matched men and 460 postmenopausal women and 416 age‐matched men. In these participants, we evaluated the correlation between
PCSK
9 plasma circulating levels and pulse wave velocity. Postmenopausal women showed higher
PCSK
9 levels (309.9±84.1 ng/mL) compared with the other groups (
P
<0.001). Older men had significant higher levels than younger men (283.2±75.6 versus 260.9±80.4 ng/mL;
P
=0.008). In the whole sample, pulse wave velocity was predicted mainly by age (B=0.116, 95%
CI
0.96–0.127,
P
<0.001),
PCSK
9 (B=0.014, 95%
CI
0.011–0.016,
P
<0.001), and serum uric acid (B=0.313, 95%
CI
0.024–0.391,
P
=0.026). Physical activity, low‐density lipoprotein cholesterol, high‐density lipoprotein cholesterol, and estimated glomerular filtration rate were not associated with pulse wave velocity (
P
>0.05).By considering the subgroups described, age and
PCSK
9 levels were mainly associated with pulse wave velocity, which also correlated with serum uric acid in postmenopausal women.

Conclusions

In the Brisighella Heart Study cohort, circulating
PCSK
9 is significantly related to arterial stiffness, independent of sex and menopausal status in women.

Published: May 2017

Background

Autologous adipose tissue–derived mesenchymal stem cells (
ATMSC
s) therapy is a promising strategy to improve post–myocardial infarction outcomes. In a porcine model of acute myocardial infarction, we studied the long‐term effects and the mechanisms involved in allogeneic
ATMSC
s administration on myocardial performance.

Methods and Results

Thirty‐eight pigs underwent 50 minutes of coronary occlusion; the study was completed in 33 pigs. After reperfusion, allogeneic
ATMSC
s or culture medium (vehicle) were intracoronarily administered. Follow‐ups were performed at short (2 days after acute myocardial infarction vehicle‐treated, n=10;
ATMSC
s‐treated, n=9) or long term (60 days after acute myocardial infarction vehicle‐treated, n=7;
ATMSC
s‐treated, n=7). At short term, infarcted myocardium analysis showed reduced apoptosis in the
ATMSC
s‐treated animals (48.6±6% versus 55.9±5.7% in vehicle;
P
=0.017); enhancement of the reparative process with up‐regulated vascular endothelial growth factor, granulocyte macrophage colony‐stimulating factor, and stromal‐derived factor‐1α gene expression; and increased M2 macrophages (67.2±10% versus 54.7±10.2% in vehicle;
P
=0.016). In long‐term groups, increase in myocardial perfusion at the anterior infarct border was observed both on day‐7 and day‐60 cardiac magnetic resonance studies in
ATMSC
s‐treated animals, compared to vehicle (87.9±28.7 versus 57.4±17.7 mL/min per gram at 7 days;
P
=0.034 and 99±22.6 versus 43.3±14.7 22.6 mL/min per gram at 60 days;
P
=0.0001, respectively). At day 60, higher vascular density was detected at the border zone in the
ATMSC
s‐treated animals (118±18 versus 92.4±24.3 vessels/mm
2
in vehicle;
P
=0.045). Cardiac magnetic resonance–measured left ventricular ejection fraction of left ventricular volumes was not different between groups at any time point.

Conclusions

In this porcine acute myocardial infarction model, allogeneic
ATMSC
s‐based therapy was associated with increased cardioprotective and reparative mechanisms and with better cardiac magnetic resonance–measured perfusion. No effect on left ventricular volumes or ejection fraction was observed.
The Role of Paradigmatic Morphology in Historical, Areal and Genealogical Linguistics
Authors: Georg Stefan 
Published: May 2017

Paradigmatic morphology is a central and crucial concept for several branches of comparative linguistics. The observation of shared paradigms in languages which were not suspected of having a common ancestry stands at the cradle of modern genealogical linguistics and dominates the discussion(s) about not firmly established or merely putative language families or phyla to this day, the very different morphological techniques different languages use for the formation of paradigms mark the beginning of language typology, now a major pillar of the language sciences, and the question, to which degree languages—closely, distantly, or not at all related with each other—may borrow morphological paradigms (part or whole) from each other or might have done so in the past (which, if true and not properly detected, might lead to superficially persuasive, but factually erroneous, claims and hypotheses of genealogical relatedness) continues to be an important theoretical and practical issue in comparative linguistics.
The contributions to this volume address, i. a., all of these questions and areas and offer much food for thought about historical morphology, areal linguistics and, above all, language classification—going far beyond the “Altaic hypothesis” , which figures prominently in some of them.
Applying Multivariate Adaptive Splines to Identify Genes With Expressions Varying After Diagnosis in Microarray Experiments
Authors: Duan Fenghai , Xu Ye 
Published: May 2017

Purpose:To analyze a microarray experiment to identify the genes with expressions varying after the diagnosis of breast cancer.Methods:A total of 44 928 probe sets in an Affymetrix microarray data publicly available on Gene Expression Omnibus from 249 patients with breast cancer were analyzed by the nonparametric multivariate adaptive splines. Then, the identified genes with turning points were grouped by K-means clustering, and their network relationship was subsequently analyzed by the Ingenuity Pathway Analysis.Results:In total, 1640 probe sets (genes) were reliably identified to have turning points along with the age at diagnosis in their expression profiling, of which 927 expressed lower after turning points and 713 expressed higher after the turning points. K-means clustered them into 3 groups with turning points centering at 54, 62.5, and 72, respectively. The pathway analysis showed that the identified genes were actively involved in various cancer-related functions or networks.Conclusions:In this article, we applied the nonparametric multivariate adaptive splines method to a publicly available gene expression data and successfully identified genes with expressions varying before and after breast cancer diagnosis.
Older Men With Anemia Have Increased Fracture Risk Independent of Bone Mineral Density

Published: May 2017

Abstract

Context:
Extremely low hemoglobin (Hgb) values have been linked to increased fracture risk at different sites. However, careful assessment of clinically defined anemia and fracture risk is lacking.

Objective:
To determine whether men with anemia were at increased risk of fracture after accounting for bone mineral density (BMD) and bone loss.

Design:
Cross-sectional analysis (at visit 3) and prospective analysis (from baseline to visit 3) in the Osteoporotic Fractures in Men (MrOS), a multisite, longitudinal cohort study.

Setting:
Six communities in the United States.

Participants:
A total of 3632 community-dwelling men (age ≥65 years) in MrOS at baseline (2000 through 2002) who were able to walk unassisted, did not have hip replacement or fracture, and had complete blood cell counts at visit 3 (2007 through 2009).

Outcomes:
Adjudicated spine and nonspine fractures during a median 7.2 years of follow-up.

Results:
Analytic baseline characteristics associated with fractures or anemia (defined as Hgb &lt;12 g/dL) were included in multivariable models. Anemia was associated with increased risk of any fracture [hazard ratio (HR), 1.67; 95% confidence interval (CI), 1.26 to 2.21] and nonspine fracture (HR, 1.70; 95% CI, 1.25 to 2.31). A model including change in BMD slightly attenuated the association with any (HR, 1.60; 95% CI, 1.20 to 2.13) and nonspine fractures (HR, 1.57; 95% CI, 1.14 to 2.15). Including absolute BMD did not significantly alter the anemia–fracture association. Anemia was not associated with spine fracture.

Conclusions:
Community-dwelling older men with anemia had a 57% to 72% increase in nonspine fracture risk independent of BMD and bone loss.
Portfolio Tax Trading with Carryover Losses
Authors: Ehling Paul , Gallmeyer Michael , Srivastava Sanjay , Tompaidis Stathis , Yang Chunyu 
Published: May 2017

We study portfolio choice with multiple stocks and capital gains taxation, assuming that capital losses can only offset current or future realized capital gains. We show, through backtesting using empirical distributions, that optimal equity holdings over an extended period are significantly lower on average than benchmark holdings suggested in the literature. Using value and growth or small and large portfolios, the backtests show that allocations remain persistently underdiversified. Carryover losses have large economic significance since they can dramatically shrink the no-trade region. Finally, the backtested economic cost of incorrectly modeling capital losses is at least 8% of lifetime wealth. The Internet appendix is available at https://doi.org/10.1287/mnsc.2017.2733 .

O ofidiário e as jararacas: acontecimento midiático, discurso político e deslizamento de sentido
Authors: Dos Santos Adelino Pereira 
Published: May 2017

Neste texto, analisamos o termo jararaca e as imagens presentes na capa e na reportagem principal da revista Veja, de 16 de março de 2016, a partir da reflexão sobre acontecimento midiático, discurso político e deslizamento de sentido, tendo como suporte teórico e metodológico a Análise de Discurso de linha francesa. Iniciamos o ensaio com a descrição de um enunciado que foi pronunciado pelo ex-presidente Luís Inácio Lula da Silva, no contexto da Operação Lava Jato, para discutir sobre o embate político, jurídico e midiático que tencionou o Brasil no mês de março de 2016. O que estamos chamando, neste ensaio, de deslizamento de sentido refere-se ao fato de o termo jararaca ser reenunciado e provocar efeitos de sentido contrários ao pretendido pelo ex-presidente Luís Inácio Lula da Silva, retomado em palavras equivalentes ou por outras semioses, sob a égide de outra formação discursiva. Esse processo discursivo demarca bem a luta política que se estabeleceu no país no primeiro semestre de 2016, retomado neste texto pela metáfora do jogo de futebol, conforme pensada por Pêcheux (2002). Courtine (2006, p. 82) destaca o papel da memória no jogo de operações que torna possível a constituição e a dispersão do discurso político: “se o interdiscurso, portanto, organiza a recorrência e o reagrupamento de formulações, igualmente intervém como uma cavidade, ruptura ou deslocamento”. Ainda, continua ele (idem), a memória se faz também de esquecimentos porque o interdiscurso “é o produtor do esquecimento dos enunciados. Memória e esquecimento não podem ser dissociados no modo de enunciação do discurso político”.
