Asian Library Journal. 9 Appendix 9.0.1 Direct Match If a summary sentence is identical to a sentence in the original, or has essentially the same content, the match is defined as a direct match. An example match that is not exact but considered to convey the same content is shown below: Manual: This paper identifies the desirable features of an ideal multisensor gas monitor and lists the different models currently available. Original: The present part lists the desirable features and the different models of portable, multisensor gas monitors currently available. 9.0.2 Direct Join If the content of the manual sentence is represented by two or more sentences in the original, the latter sentences are noted as joins. For example: Manual: In California, Caltrans has a rolling pavement management program, with continuouscollection of data with the aim of identifying roads that require more monitoring and repair. Original (1): Rather than conducting biennial surveys, Caltrans now has a rolling pavement-management program, with data collected continuously. Original (2): The idea is to pinpoint the roads that may need more or less monitoring and repair. 9.0.3 Incomplete Matches A sentence in the original document is labelled as an incomplete match if it only partially covers the content of a manual summary sentence, or if a direct match is not clear. It can occur in the context of a single sentence or a join. The following exemplifies an incomplete single sentence match: Manual: Intergranular fracture of polycrystalline Ni3Alwas studied at 77K. Original: Before discussing the observeddeformation and fracture behavior of polycrystalline Ni3Al at 77K in terms of the kinetics of the proposed environmental embrittlement mechanism, we should ask whether the low temperature by itself significantly affects the brittleness of Ni3Al.
Clinical and laboratory features of human dirofilariasis in Russia

The article presents the results of the prospective study of 266 patients with dirofilariasis who received medical and diagnostic assistance in Rostov Scientific Research Institute of Microbiology and Parasitology in Rostov-on-Don, Russia from 2000 to 2016. We have assessed the features of the dynamics of epidemiology of this infection in several territories of the Russian Federation, depending on the social structure of patients. Immature females of dirofilaria were found most commonly in humans (82.9 ± 2.6%), the proportion of maturity females and adult males of worms respectively was 10.5 ± 2.1% and 0.9 ± 0.6%. All mature worms were localized inside a capsule. Peripheral blood eosinophilia was detected only in patients with the migration of helminths (19 of 116 persons - 16.4%). Blood samples of patients examined by the method of concentration in 3% acetic acid for detection of microfilariae, showed negative result in all patients. Our data are consistent with the opinion of KI Skriabin about that human as «dual facultative host» for dirofiliaria. It is rare that parasite in human body is able to develop to the imago stage (according to our observations - 11.4%). The immune response to invasion by dirofiliaria in human is manifested as dense connective tissue which forms a capsule. According to our study the rare cases (22) of detection the sexual mature D. repens (10.4%) were localized inside the capsule. Observations of patients with D. repens infection allowed concluding that human for this helminth is «a biological deadend».
The Antibacterial Activity of Leaf Extracts of Eucalyptus camaldulensis (Myrtaceae)

The antibacterial activity of the leaf extracts of Eucalyptus camaldulensis was studied against Klebsiella spp, Salmonella typhi, Yersinia enterocolitica, Pseudomonas aeruginosa (Gram-negative), Staphylococcus aureus and Bacillus subtilis by the agar diffusion method. The methanol extract, dichloromethane fraction and methanol residue at 10mg mL displayed broad spectrum activity against -1 all the test organisms but the petroleum ether fraction showed no activity. The antibacterial activity of the extracts was compared to the drug gentamycin. The minimum inhibitory concentrations of the methanol extract and dichloromethane fraction determined by the agar dilution method ranged between 0.04 and 10mg mL with that of Bacillus subtilis being the least. Phytochemical screening of the plant revealed -1 the presence of tannins, saponins and cardiac glycosides. The results of this study support the traditional use of Eucalyptus camaldulensis leaves as an antibacterial agent.
Psychological traits and the cortisol awakening response: Results from the Netherlands Study of Depression and Anxiety

BACKGROUND
Hypothalamus-Pituitary-Adrenal (HPA) axis dysregulation is often seen in major depression, and is thought to represent a trait vulnerability - rather than merely an illness marker - for depressive disorder and possibly anxiety disorder. Vulnerability traits associated with stress-related disorders might reflect increased sensitivity for the development of psychopathology through an association with HPA axis activity. Few studies have examined the association between psychological trait factors and the cortisol awakening response, with inconsistent results. The present study examined the relationship between multiple psychological trait factors and the cortisol awakening curve, including both the dynamic of the CAR and overall cortisol awakening levels, in a sample of persons without psychopathology, hypothesizing that persons scoring high on vulnerability traits demonstrate an elevated cortisol awakening curve.


METHODS
From 2981 participants of the Netherlands Study of Depression and Anxiety (NESDA), baseline data from 381 controls (aged 18-65) without previous, current and parental depression and anxiety disorders were analyzed. Psychological measures included the Big Five personality traits (neuroticism, extraversion, openness to experience, conscientiousness, and agreeableness) measured using the NEO-FFI, anxiety sensitivity assessed by the Anxiety Sensitivity Index, cognitive reactivity to sadness (hopelessness, acceptance/coping, aggression, control/perfectionism, risk aversion, and rumination) as measured by the LEIDS-R questionnaire, and mastery, assessed using the Pearlin and Schooler Mastery scale. Salivary cortisol levels were measured at awakening, and 30, 45, and 60 min afterwards.


RESULTS
In adjusted analyses, high scores of hopelessness reactivity (β=.13, p=.02) were consistently associated with a higher cortisol awakening response. In addition, although inconsistent across analyses, persons scoring higher on extraversion, control/perfectionism reactivity, and mastery tended to show a slightly flatter CAR. No significant associations were found for neuroticism, openness to experience, agreeableness, conscientiousness, anxiety sensitivity, and acceptance/coping, aggression, or risk aversion reactivity.


CONCLUSION
Of various psychological traits, only hopelessness reactivity, a trait that has been associated with depression and suicidality, is consistently associated with HPA axis dysregulation. Hopelessness reactivity may represent a predisposing vulnerability for the development of a depressive or anxiety disorder, possibly in part mediated by HPA axis activity.
Genes for elite power and sprint performance: ACTN3 leads the way.

The ability of skeletal muscles to produce force at a high velocity, which is crucial for success in power and sprint performance, is strongly influenced by genetics and without the appropriate genetic make-up, an individual reduces his/her chances of becoming an exceptional power or sprinter athlete. Several genetic variants (i.e. polymorphisms) have been associated with elite power and sprint performance in the last few years and the current paradigm is that elite performance is a polygenic trait, with minor contributions of each variant to the unique athletic phenotype. The purpose of this review is to summarize the specific knowledge in the field of genetics and elite power performance, and to provide some future directions for research in this field. Of the polymorphisms associated with elite power and sprint performance, the α-actinin-3 R577X polymorphism provides the most consistent results. ACTN3 is the only gene that shows a genotype and performance association across multiple cohorts of elite power athletes, and this association is strongly supported by mechanistic data from an Actn3 knockout mouse model. The angiotensin-1 converting enzyme insertion/deletion polymorphism (ACE I/D, registered single nucleotide polymorphism [rs]4646994), angiotensinogen (AGT Met235Thr rs699), skeletal adenosine monophosphate deaminase (AMPD1) Gln(Q)12Ter(X) [also termed C34T, rs17602729], interleukin-6 (IL-6 -174 G/C, rs1800795), endothelial nitric oxide synthase 3 (NOS3 -786 T/C, rs2070744; and Glu298Asp, rs1799983), peroxisome proliferator-activated receptor-α (PPARA Intron 7 G/C, rs4253778), and mitochondrial uncoupling protein 2 (UCP2 Ala55Val, rs660339) polymorphisms have also been associated with elite power performance, but the findings are less consistent. In general, research into the genetics of athletic performance is limited by a small sample size in individual studies and the heterogeneity of study samples, often including athletes from multiple-difference sporting disciplines. In the future, large, homogeneous, strictly defined elite power athlete cohorts need to be established though multinational collaboration, so that meaningful genome-wide association studies can be performed. Such an approach would provide unbiased identification of potential genes that influence elite athletic performance.
A Decade of Lattice Cryptography

Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn as the foundation for secure cryptographic systems. Attractive features of lattice cryptography include apparent resistance to quantum attacks (in contrast with most number-theoretic cryptography), high asymptotic efficiency and parallelism, security under worst-case intractability assumptions, and solutions to long-standing open problems in cryptography. This work surveys most of the major developments in lattice cryptography over the past ten years. The main focus is on the foundational short integer solution (SIS) and learning with errors (LWE) problems (and their more efficient ring-based variants), their provable hardness assuming the worst-case intractability of standard lattice problems, and their many cryptographic applications.

How to evaluate the microcirculation: report of a round table conference

INTRODUCTION
Microvascular alterations may play an important role in the development of organ failure in critically ill patients and especially in sepsis. Recent advances in technology have allowed visualization of the microcirculation, but several scoring systems have been used so it is sometimes difficult to compare studies. This paper reports the results of a round table conference that was organized in Amsterdam in November 2006 in order to achieve consensus on image acquisition and analysis.


METHODS
The participants convened to discuss the various aspects of image acquisition and the different scores, and a consensus statement was drafted using the Delphi methodology.


RESULTS
The participants identified the following five key points for optimal image acquisition: five sites per organ, avoidance of pressure artifacts, elimination of secretions, adequate focus and contrast adjustment, and recording quality. The scores that can be used to describe numerically the microcirculatory images consist of the following: a measure of vessel density (total and perfused vessel density; two indices of perfusion of the vessels (proportion of perfused vessels and microcirculatory flow index); and a heterogeneity index. In addition, this information should be provided for all vessels and for small vessels (mostly capillaries) identified as smaller than 20 microm. Venular perfusion should be reported as a quality control index, because venules should always be perfused in the absence of pressure artifact. It is anticipated that although this information is currently obtained manually, it is likely that image analysis software will ease analysis in the future.


CONCLUSION
We proposed that scoring of the microcirculation should include an index of vascular density, assessment of capillary perfusion and a heterogeneity index.
Organizations as complex adaptive systems: Implications of Complexity Theory for leadership research

This article contrasts the assumptions of General Systems Theory, the framework for much prior leadership research, with those of Complexity Theory, to further develop the latter's implications for the definition of leadership and the leadership process. We propose that leadership in a Complex Adaptive System (CAS) may affect the organization indirectly, through the mediating variables of organizational identity and social movements. A rudimentary model of leadership in a CAS is presented. We then outline two non-linear methodologies, dynamic systems simulation and artificial neural networks, as appropriate to enable development and testing of a model leadership under the assumptions of Complexity Theory. © 2006 Elsevier Inc.

Dissolution enhancement of glimepiride using modified gum karaya as a carrier

OBJECTIVE
The aim of present investigation is to enhance in vitro dissolution of poorly soluble drug glimepiride by preparing solid dispersions using modified gum karaya.


MATERIALS AND METHODS
Solid dispersions of drug were prepared by solvent evaporation method using modified gum karaya as carrier. Four batches of solid dispersion (SD1, SD4, SD9, and SD14) and physical mixture (PM1, PM4, PM9, and PM14) were prepared and characterized by differential scanning colorimetry (DSC), Fourier transform infrared (FTIR) spectroscopy, powder X-Ray diffraction (X-RD), and scanning electron microscopy (SEM) studies. Equilibrium solubility studies were carried out in shaker incubator for 24 h and in vitro drug release was determined using USP Dissolution Apparatus-II.


RESULTS
Maximum solubility and in vitro dissolution were observed with Batch SD4. No significant enhancement of dissolution characteristics were observed in the corresponding physical mixture PM4. Low viscosity with comparable swelling characteristics as compared to GK of modified form of gum karaya may lead to improvement in dissolution behavior of solid dispersion batches. Also, the conversion of crystalline form of drug to amorphous form may be a responsible factor, which was further confirmed by DSC, FTIR studies, and X-RD studies. SEM photographs of batch SD4 revealed porous nature of particle surface.


CONCLUSION
Modified forms of natural carriers prove beneficial in dissolution enhancement of poorly soluble drugs and exhibited a great potential in novel drug delivery systems.
Non-valvular atrial fibrillation in the elderly; preliminary results from the National AFTER (Atrial Fibrillation in Turkey: Epidemiologic Registry) Study.

OBJECTIVE
This study aimed at the assessment of the clinical approach to atrial fibrillation (AF) in the older population and the consistency with the guidelines based on the records of the multicenter, prospective AFTER (Atrial Fibrillation in Turkey: Epidemiologic Registry) study.


PATIENTS AND METHODS
2242 consecutive patients admitted to the Cardiology Outpatient Clinics of 17 different tertiary Health Care Centers with at least one AF attack determined on electrocardiographic examination, were included in the study. Among the patients included in the study, 631 individuals aged 75 years and older were analyzed.


RESULTS
The mean age of the patients was determined as 80.3±4.2 years. The most frequent type of AF in geriatric population was the persistent-permanent type with a percentage of 88%. 60% of the patients with AF were female. Hypertension was the most common co-morbidity in patients with AF (76%). While in 16% of patients a history of stroke, transient ischemic attack or systemic thromboembolism was present, a history of bleeding was present in 14% of the patients. 37% of the patients were on warfarin treatment and 60% of the patients were on aspirin treatment. In 38% of the patients who were on oral anticoagulant treatment, INR level was in the effective range.


CONCLUSIONS
The rate of anticoagulant use in the elderly with AF was 37% and considering the reason of this situation was the medication not being prescribed by the physician, one should pay more attention particularly in the field of treatment.
Introduction to Probabilistic Topic Models

Probabilistic topic models are a suite of algorithms whose aim is to discover the hidden thematic structure in large archives of documents. In this article, we review the main ideas of this field, survey the current state-of-the-art, and describe some promising future directions. We first describe latent Dirichlet allocation (LDA) [8], which is the simplest kind of topic model. We discuss its connections to probabilistic modeling, and describe two kinds of algorithms for topic discovery. We then survey the growing body of research that extends and applies topic models in interesting ways. These extensions have been developed by relaxing some of the statistical assumptions of LDA, incorporating meta-data into the analysis of the documents, and using similar kinds of models on a diversity of data types such as social networks, images and genetics. Finally, we give our thoughts as to some of the important unexplored directions for topic modeling. These include rigorous methods for checking models built for data exploration, new approaches to visualizing text and other high dimensional data, and moving beyond traditional information engineering applications towards using topic models for more scientific ends.
A Review on Distributed Application Processing Frameworks in Smart Mobile Devices for Mobile Cloud Computing

The latest developments in mobile devices technology have made smartphones as the future computing and service access devices. Users expect to run computational intensive applications on Smart Mobile Devices (SMDs) in the same way as powerful stationary computers. However in spite of all the advancements in recent years, SMDs are still low potential computing devices, which are constrained by CPU potentials, memory capacity and battery life time. Mobile Cloud Computing (MCC) is the latest practical solution for alleviating this incapacitation by extending the services and resources of computational clouds to SMDs on demand basis. In MCC, application offloading is ascertained as a software level solution for augmenting application processing capabilities of SMDs. The current offloading algorithms offload computational intensive applications to remote servers by employing different cloud models. A challenging aspect of such algorithms is the establishment of distributed application processing platform at runtime which requires additional computing resources on SMDs. This paper reviews existing Distributed Application Processing Frameworks (DAPFs) for SMDs in MCC domain. The objective is to highlight issues and challenges to existing DAPFs in developing, implementing, and executing computational intensive mobile applications within MCC domain. It proposes thematic taxonomy of current DAPFs, reviews current offloading frameworks by using thematic taxonomy and analyzes the implications and critical aspects of current offloading frameworks. Further, it investigates commonalities and deviations in such frameworks on the basis significant parameters such as offloading scope, migration granularity, partitioning approach, and migration pattern. Finally, we put forward open research issues in distributed application processing for MCC that remain to be addressed.
The Complexity of Satisfiability Problems: Refining Schaefer's Theorem

Schaefer proved in 1978 that the Boolean constraint satisfaction problem for a given constraint language is either in P or is NP-complete, and identified all tractable cases. Schaefer’s dichotomy theorem actually shows that there are at most two constraint satisfaction problems, up to polynomial-time isomorphism (and these isomorphism types are distinct if and only if P 6= NP). We show that if one considers AC isomorphisms, then there are exactly six isomorphism types (assuming that the complexity classes NP, P,⊕L, NL, and L are all distinct).
Two-dose versus monthly intermittent preventive treatment of malaria with sulfadoxine-pyrimethamine in HIV-seropositive pregnant Zambian women.

BACKGROUND
Intermittent preventive treatment of malaria during pregnancy (IPTp) reduces placental infection, maternal anemia, and low birth weight (LBW). However, the optimal dosing regimen in settings in which human immunodeficiency virus (HIV) is highly prevalent among pregnant women remains controversial.


METHODS
We conducted a randomized, double-blind, placebo-controlled study of IPTp comparing the standard 2-dose sulfadoxine-pyrimethamine (SP) regimen with monthly IPTp among a cohort of HIV-positive pregnant Zambian women. Primary outcomes included placental malaria (by smear and histology) and maternal peripheral parasitemia at delivery.


RESULTS
There were no differences between monthly IPTp (n=224) and standard IPTp (n=232) in placental malaria by histopathology (26% vs. 29%; relative risk [RR], 0.90 [95% confidence interval {CI}, 0.64-1.26]) or placental parasitemia (2% vs. 4%; RR, 0.55 [95% CI, 0.17-1.79]). There also were no differences in maternal anemia, stillbirths, preterm delivery, LBW, or all-cause mortality of infants at 6 weeks.


CONCLUSIONS
In an area of mesoendemicity in Zambia, monthly SP IPTp was not more efficacious than the standard 2-dose regimen for the prevention of placental malaria or adverse birth outcomes. IPTp policy recommendations need to take into account local malaria transmission patterns and the prevalence of HIV.

Model-Driven Development of Mobile Personal Health Care Applications

Personal health care applications on mobile devices allow patients to enhance their health via reminders, monitoring and feedback to health care providers. Engineering such applications is challenging with a need for health care plan meta-models, per-patient instantiation of care plans, and development and deployment of supporting Web and mobile device applications. We describe a novel prototype environment for visually modelling health care plans and automated plan and mobile device application code generation.
