Utilizing AHP: Resource Allocation Problem in Cloud

Cloud Computing is changing the scheme by providing different services to business and government sectors as well as to sole users irrespective of their location. Cloud Computing provides scalable and on demand services to users, but this technology has many challenges. In several applications the last decision is based on the estimate of a number of alternatives in terms of a number of criteria. This problem may become difficult one when criteria are expressed in different tasks or jobs, relevant data are difficult to be quantified. The Analytic Hierarchy Process (AHP) is an effective method dealing with this kind of decision problems. This paper deals with priorities, ranking with consistency method and their results are given through a numerical example. The results show that distributive mode has fast convergence and smaller computational complexity than ideal mode for close system when the AHP method is used in cloud computing applications.
SparseLeap: Efficient Empty Space Skipping for Large-Scale Volume Rendering

Recent advances in data acquisition produce volume data of very high resolution and large size, such as terabyte-sized microscopy volumes. These data often contain many fine and intricate structures, which pose huge challenges for volume rendering, and make it particularly important to efficiently skip empty space. This paper addresses two major challenges: (1) The complexity of large volumes containing fine structures often leads to highly fragmented space subdivisions that make empty regions hard to skip efficiently. (2) The classification of space into empty and non-empty regions changes frequently, because the user or the evaluation of an interactive query activate a different set of objects, which makes it unfeasible to pre-compute a well-adapted space subdivision. We describe the novel SparseLeap method for efficient empty space skipping in very large volumes, even around fine structures. The main performance characteristic of SparseLeap is that it moves the major cost of empty space skipping out of the ray-casting stage. We achieve this via a hybrid strategy that balances the computational load between determining empty ray segments in a rasterization (object-order) stage, and sampling non-empty volume data in the ray-casting (image-order) stage. Before ray-casting, we exploit the fast hardware rasterization of GPUs to create a ray segment list for each pixel, which identifies non-empty regions along the ray. The ray-casting stage then leaps over empty space without hierarchy traversal. Ray segment lists are created by rasterizing a set of fine-grained, view-independent bounding boxes. Frame coherence is exploited by re-using the same bounding boxes unless the set of active objects changes. We show that SparseLeap scales better to large, sparse data than standard octree empty space skipping.
Implantable biomedical microsystems for neural prostheses

In the following article, the technologies to fabricate polyimide-based thin and flexible substrates with monolithically integrated electrode arrays and printed circuit boards (PCB) for hybrid electronic assemblies as well as an assembling technique that connects bare electronic dice with flexible PCBs are presented. The concept of modular, flexible biomedical microsystems as neural prostheses is introduced in general and described in detail in three examples. A cuff electrode with integrated multiplexer circuitry and standard implantable cables represents the combination of microtechnology with precision mechanics; a sieve electrode used as an implant in peripheral nerve regeneration studies demonstrates the next level of integration density but still uses a cable connection; and last, joint effort to fabricate the demonstrator of a vision prosthesis that is completely implantable in the eye with a wireless link for energy supply and data transmission is presented. System design, hybrid assembling technology, and flexible multilayer encapsulation using parylene and silicone rubber are the key components for creating a new generation of neural prostheses for complex and challenging new applications.
Assessing the effects of global warming and local social and economic conditions on the malaria transmission.

OBJECTIVE To show how a mathematical model can be used to describe and to understand the malaria transmission. METHODS The effects on malaria transmission due to the impact of the global temperature changes and prevailing social and economic conditions in a community were assessed based on a previously presented compartmental model, which describes the overall transmission of malaria. RESULTS/CONCLUSIONS The assessments were made from the scenarios produced by the model both in steady state and dynamic analyses. Depending on the risk level of malaria, the effects on malaria transmission can be predicted by the temperature ambient or local social and-economic conditions.
Perceptions of Adolescents' Influence in Family Decision Making.

This study examined adolescents' influence on family decision making. The Decision Making Survey (DMS), a self-administered questionnaire, was created to present a variety of the decisions made within the family. Items on the DMS were categorized into eight domains of family life (entertainment, purchases, family environment/daily living activities, school-related activities, rules and regulation, conservation, finances, and politics/religion/social activism) to determine in which domains adolescents and their mothers perceived the adolescents to have a greater level of influence. The items on the DMS were also classified into two focus categories: adolescent-centered, which related directly to the adolescent, and family-centered, which related to other family members or the family as a whole. Participants were 111 ninth graders and their mothers. They were primarily white and from an upper middle class background. Generally, adolescents and their mothers perceived the adolescents to have differential influence based on domain of family life. Both adolescents and their mothers also perceived the adolescents to have higher levels of control over adolescent-centered items such as school-related activities than over family-centered items such as finances and conservation.

Aerosol Lidar observations and model calculations of the Planetary Boundary Layer evolution over Greece, during the March 2006 Total Solar Eclipse

An investigation of the Planetary Boundary Layer (PBL) height evolution over Greece, during the solar eclipse of 29 March 2006, is presented. Ground based observations were carried out using lidar detection and ranging devices and ground meteorological instruments, to estimate the height of the mixing layer (ML) before, during and after the solar eclipse in northern and southern parts of Greece exhibiting different sun obscuration. Data demonstrate that the solar eclipse has induced a decrease of the PBL height, indicating a suppression of turbulence activity similar to that during the sunset hours. The changes in PBL height were associated with a very shallow entrainment zone, indicating a significant weakening of the penetrative convection. Heat transfer was confined to a thinner layer above the ground. The thickness of the entrainment zone exhibited its minimum during the maximum of the eclipse, demonstrative of turbulence mechanisms suppression at that time. Model estimations of the PBL evolution were additionally conducted using the Comprehensive Air Quality Model with extensions (CAMx) coupled with the Weather Research and Forecasting model (WRF). Model-diagnosed PBL height decrease during the solar eclipse due to vertical transport decay, in agreement with the experimental findings; vertical profiles of atmospheric particles and gaseous species showed an important vertical mixing attenuation.
Oxidized lipoproteins degrade the endothelial surface layer : implications for platelet-endothelial cell adhesion.

BACKGROUND Flowing erythrocytes and platelets are separated from the luminal endothelial cell (EC) surface by a 0.5-microm-wide space named the endothelial surface layer. We hypothesized that the disruption of the endothelial surface layer by oxidized low-density lipoproteins (Ox-LDL) contributes to atherogenic increases in vascular wall adhesiveness. METHODS AND RESULTS The hamster cremaster muscle preparation was used for intravital microscopic observation of the distance between erythrocytes and the capillary EC surface. Moderate Ox-LDL was prepared by exposing native LDL to CuSO(4) for 6 hours. The dimension of the EC surface layer averaged 0.6+/-0.1 microm during control situations, but a bolus intravenous injection of Ox-LDL (0.4 mg/100 g of body weight) transiently diminished the EC surface layer by 60% within 25 minutes, which correlated with a transient increase in the number of platelet-EC adhesions. Combined administration of superoxide dismutase and catalase completely blocked the effect of Ox-LDL on the dimension of the EC surface layer and inhibited platelet-EC adhesion. CONCLUSIONS Oxygen-derived free radicals mediate the disruption of the EC surface layer and increase vascular wall adhesiveness by Ox-LDL.
A Personalization Recommendation Algorithm for E-Commerce

Many recommendation systems employ the collaborative filtering technology, which has been proved to be one of the most successful techniques in recommendation systems in recent years, the difficulties of the extreme sparsity of user rating data have become more and more severe. To solve the problems of scalability and sparsity in the collaborative filtering, this paper proposed a personalization recommendation algorithm based on rough set which is proposed, The algorithm refine the user ratings data with dimensionality reduction, then uses a new similarity measure to find the target users’ neighbors, then generates recommendations. To prove our algorithm’s effectiveness, the authors conduct experiments on the public dataset. Theoretical analysis and experimental results show that this method is efficient and effective.
Resonance energy transfer between points in a reconstituted skeletal muscle thin filament. A conformational change of the thin filament in response to a change in Ca2+ concentration.

The spatial relationships between Lys-61, Cys-374 on actin or SH1 on myosin subfragment-1 (S1) and Cys-190 on tropomyosin or Cys-133 on troponin-I (TnI) in a reconstituted thin filament were studied by fluorescence resonance energy transfer. 5-(2-Iodoacetylaminoethyl)aminonaphthalene 1-sulfonic acid (IAEDANS) attached to Lys-190 on tropomyosin or to Cys-133 on TnI was used as a donor. Fluorescein 5-isothiocyanate (FITC) attached to Lys-61 or 5-(iodoacetoamido)fluorescein (IAF) attached to Cys-374 on actin and 4-dimethylaminophenyl-azophenyl 4'-maleimide (DABMI) attached to SH1 on S1 were used as an acceptor. The transfer efficiency between AEDANS attached to Cys-190 on tropomyosin and FITC attached to Lys-61 on actin was 0.42 in the absence of troponin, 0.46 in the presence of troponin and Ca2+ and 0.55 in the presence of troponin and absence of Ca2+. The corresponding distances between the probes were calculated to be 4.7 nm, 4.6 nm and 4.3 nm respectively, assuming a random orientation factor K2 = 2/3. A large difference in the transfer efficiency from AEDANS attached to Cys-133 on TnI to FITC attached to Lys-61 on actin was observed between in the presence (0.52) and absence (0.70) of Ca2+. The corresponding distances between the probes were calculated to be 4.5 nm in the presence of Ca2+ and 3.9 nm in the absence of Ca2+. The distance between Cys-190 on tropomyosin and Cys-374 on actin was measured to be 5.1 nm and the transfer efficiency (0.35) did not change upon addition of troponin whether Ca2+ is present or not, in agreement with the previous report [Tao, T. , Lamkin, M. & Lehrer, S. S. (1983) Biochemistry 22, 3059-3064]. The distance between Cys-133 on TnI and Cys-374 on actin was measured to be 4.4 nm. No detectable change in transfer efficiency (0.58) was observed between values in the presence and absence of Ca2+. These results suggest that a relative movement of the two domains of actin monomer in a reconstituted thin filament occurs in response to a change in Ca2+ concentration. The transfer efficiencies between DABMI attached to SH1 on S1 and AEDANS attached to Cys-190 on tropomyosin or Cys-133 on TnI were too small (less than 2%) for an accurate estimation of the distances, suggesting the distances are longer than 7.3 nm.
Molecular and Cellular Pathobiology Reprogramming the Chromatin Landscape : Interplay of the EstrogenandGlucocorticoidReceptors at theGenomicLevel

Cross-talk between estrogen receptors (ER) and glucocorticoid receptors (GR) has been shown to contribute to the development and progression of breast cancer. Importantly, the ER and GR status in breast cancer cells is a significant factor in determining the outcome of the disease. However, mechanistic details defining the cellular interactions between ER andGR are poorly understood.We investigated genome-wide binding profiles for ER and GR upon coactivation and characterized the status of the chromatin landscape. We describe a novel mechanism dictating themolecular interplay between ER andGR. Upon induction, GRmodulates access of ER to specific sites in the genome by reorganization of the chromatin configuration for these elements. Binding to these newly accessible sites occurs either by direct recognition of ER response elements or indirectly through interactions with other factors. The unveiling of this mechanism is important for understanding cellular interactions between ER and GR and may represent a general mechanism for cross-talk between nuclear receptors in human disease.

Some New Results for the Semidefinite Linear Complementarity Problem

In this paper, we present some new results for the semidefinite linear complementarity problem (SDLCP). In the first part, we introduce the concepts of (i) nondegeneracy for a linear transformation $L:{\cal S}^n \rightarrow {\cal S}^n$ and (ii) the locally-star-like property of a solution point of an SDLCP(L,Q) for $Q\in {\cal S}^n$, and we relate them to the finiteness of the solution set of SDLCP(L,Q) as Q varies in ${\cal S}^n$. In the second part, we show that for positive stable matrices A1,. , Ak, the linear transformation L:=LA1 \circ L_{A_2} \circ \cdots \circ L_{A_k} $ has the Q-property where LAi(X):= AiX + XAiT. A similar result is proved for the transformation $S:=S_{A_1} \circ S_{A_2} \circ \cdots \circ S_{A_k}$, where each Ai is Schur stable and $S_{A_i}(X):=X-A_iXA_i^{T}$. We relate these results to the simultaneous stability of a finite set of matrices.
Parkinsonpatienten mit Ödemen und depressiven Symptomen

Zusammenfassung Bei Parkinson sind zunehmend nicht motorische Symptome von Bedeutung. Deshalb sollte durch die dopaminerge Therapie neben guter motorischer Wirksamkeit ein möglichst positiver Einfluss auf nicht motorische Symptome erreicht werden. Der Non-Ergot Dopaminagonist (DA) Piribedil besitzt ein spezifisches Rezeptorprofil mit D2/D3-Agonismus und α2-Antagonismus. Bei einer 67-jährigen Patientin mit Tagesmüdigkeit unter PramipexolVormedikation traten unter Therapie mit Ropinirol, L-Dopa und Rasagilin motorische Probleme auf. Zudem bestanden leichte Beinödeme und ein deutliches depressives Syndrom. Der DA wurde auf Piribedil gewechselt. Nach Therapieumstellung und weiterer Dosisanpassung besserte sich die Motorik ohne Auftreten von Tagesmüdigkeit. Die Ödeme gingen zurück und bei deutlich gebesserter Stimmungslage konnte der eindosierte SSRI abgesetzt werden. Ein DA-Wechsel kann bei Auftreten spezifischer Probleme günstig sein. Bei guter motorischer Wirksamkeit zeigte Piribedil in dieser Kasuistik Vorteile in Bezug auf Tagesmüdigkeit und Ödeme mit zusätzlich antidepressiver Wirkung.
Marine Incursion: The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion into West Africa

The spectacular marine-like diversity of the endemic fauna of Lake Tanganyika, the oldest of the African Great Lakes, led early researchers to suggest that the lake must have once been connected to the ocean. Recent geophysical reconstructions clearly indicate that Lake Tanganyika formed by rifting in the African subcontinent and was never directly linked to the sea. Although the Lake has a high proportion of specialized endemics, the absence of close relatives outside Tanganyika has complicated phylogeographic reconstructions of the timing of lake colonization and intralacustrine diversification. The freshwater herring of Lake Tanganyika are members of a large group of pellonuline herring found in western and southern Africa, offering one of the best opportunities to trace the evolutionary history of members of Tanganyika's biota. Molecular phylogenetic reconstructions indicate that herring colonized West Africa 25–50MYA, at the end of a major marine incursion in the region. Pellonuline herring subsequently experienced an evolutionary radiation in West Africa, spreading across the continent and reaching East Africa's Lake Tanganyika during its early formation. While Lake Tanganyika has never been directly connected with the sea, the endemic freshwater herring of the lake are the descendents of an ancient marine incursion, a scenario which may also explain the origin of other Tanganyikan endemics.
Optical Coherence Tomography Angiography as an Imaging Modality for Evaluation of Diabetic Macular Edema

359 Diabetic retinopathy remains a leading cause of blindness worldwide in patients aged 20–64 years. [1] Diabetic macular edema (DME) threating or involving the fovea is a common etiology for vision loss. Traditionally, treatment methods have been guided by contact and non‐contact slit lamp biomicroscopy, fluorescein angiography and fundus stereo photography. [1] Fluorescein angiography (FA) is a dynamic, invasive imaging technique first described in 1961 and more thoroughly invested and popularized by Gass in 1967. [2] In principle, this technique uses a series of exciting and barrier filters to visualize fluorescein dye excursion through retinal arterial, capillary, and venous structures as well as the underlying choroid. It remains the gold standard in evaluation of macular perfusion and localizes the area of leakage in non‐proliferative diabetic retinopathy, neovascularization in proliferative diabetic disease and detecting choroidal neovascular membrane (CNVM) and other retinal vascular diseases. Though FA provides detailed anatomy of retinal vascular structure and dynamic circulation parameters, it has several limitations: it requires intravenous administration of fluorescein dye, which infrequently results in nausea, gastrointestinal upset, very rarely serious allergic reaction and anaphylaxis. In addition, its time‐consuming nature hinders its use in busy clinical settings. [3] Furthermore, interpretation of images is subjective and user dependent. Finally, its use in patients with small pupils or media clarity issues such as vitreous hemorrhage is limited. In 1991, the advent of a new non‐invasive imaging technique known as optical coherence tomography (OCT) revolutionized the management of a variety of retinal diseases including macular edema. [4] The principle behind OCT involves directing a beam of infra‐red light (830 nm) orthogonal to the surface of the retina while a recorder captures and analyzes the signal reflection. [5] The result is a 3‐D reflectance image that provides detailed anatomy of the intra‐retinal structures, posterior hyaloid and macular Optical Coherence Tomography Angiography as an Imaging Modality for Evaluation of Diabetic Macular Edema
Parents as Pain Killers in the Pain Management of Preterm Infants

The aim of this study was to develop a new pain management method called facilitated tucking by parents (FTP) to alleviate procedural pain in preterm infants in the Neonatal Intensive Care Unit (NICU). In two randomized controlled crossover trials, the effectiveness of FTP was compared to a non-pharmacological evidence-based practice (oral glucose), a pharmacological method (intravenous oxycodone) and a placebo (oral water) or control care in the context of heel lance and endotracheal or pharyngeal suctioning. In addition, the short-term adverse effects (desaturation, bradycardia) and the prolonged effects of pain management on sleep were measured. The gestational age of the infants was a median of 28 weeks (n=20) in Study I and a mean of 28 1/7 (n=20) in Study II. The primary outcome measure for procedural pain was the Premature infant pain profile (PIPP). After interventions, sleep structure was analysed from 13-hour polysomnographic recordings. In the third study, the mothers (n = 23) who had used FTP from 2-4 weeks in the NICU were interviewed using the Clinical interview for parents of high-risk infants with additional questions related to the infants’ pain care. During heel lance, the PIPP scores were significantly lower with oral glucose (mean 4.85 ± 1.73, p≤0.001) and FTP (mean 5.20 ± 1.70, p=0.004) when compared to the placebo (mean 7.05 ± 2.16). During pharyngeal suctioning, the scores were lower with oral glucose (mean 11.05 ± 2.31, p=0.014) and FTP (mean 11.25 ± 2.47, p=0.034) compared to the placebo (mean 12.40 ± 2.06). Opioid equalled placebo during both procedures. Significantly more short-term adverse effects were related to the administration of oral glucose (21.3%) and oral water (12.5%) compared to opioid (5%) or FTP (5%). Oxycodone treatment altered the sleep structure by significantly decreasing the amount of REM sleep. The FTP was positively perceived by all participating parents. In the mothers, three different styles of involvement in pain care were identified. The differences found in the involvement of pain care were related to maternal attachment and NICUrelated stress of the mothers. The FTP was preferable to oral glucose and intravenous oxycodone when efficacy, safety and family issues were considered in treating short-term procedural pain in preterm infants.
Active Learning with Cross-Class Knowledge Transfer

When there are insufficient labeled samples for training a supervised model, we can adopt active learning to select the most informative samples for human labeling, or transfer learning to transfer knowledge from related labeled data source. Combining transfer learning with active learning has attracted much research interest in recent years. Most existing works follow the setting where the class labels in source domain are the same as the ones in target domain. In this paper, we focus on a more challenging cross-class setting where the class labels are totally different in two domains but related to each other in an intermediary attribute space, which is barely investigated before. We propose a novel and effective method that utilizes the attribute representation as the seed parameters to generate the classification models for classes. And we propose a joint learning framework that takes into account the knowledge from the related classes in source domain, and the information in the target domain. Besides, it is simple to perform uncertainty sampling, a fundamental technique for active learning, based on the framework. We conduct experiments on three benchmark datasets and the results demonstrate the efficacy of the proposed method.
