Cloud Service Level planning under burstiness (2013)

Cloud Service Providers (SPs) need tools to help them plan their infrastructure capacity and decide on Service Level Agreements (SLAs) with their customers prior to deploying customer's applications. Existing approaches have not considered several important challenges such as workload burstiness, workload uncertainty, and scalability to large number of applications. This paper proposes a trace-based framework to address these challenges simultaneously. The core of the framework is a novel Resource Allocation Planning (RAP) methodology which allows SPs to take into account workload burstiness in Service Level Planning (SLP). This methodology works in consort with a Monte Carlo simulation technique to systematically consider the impact of workload uncertainty in SLP. Furthermore, we propose a novel burstiness-aware clustering technique that groups applications with similar workload characteristics to improve the scalability of the SLP framework. Results show that our approach can yield near optimal resource allocations and can achieve lower SLO violations with fewer resources than competing approaches, especially for bursty workloads. Furthermore, our proposed clustering technique is able to improve the scalability of our SLP framework without significantly impacting resource allocation accuracy.
Complications Using Intense Ultrasound Therapy to Treat Deep Dermal Facial Skin and Subcutaneous Tissues (2014)

Although most of the complications were transient in nature, 1 patient developed persistent facial edema that became a scar and another developed pseudomelolabial fat atrophy. Furthermore, 3 patients experienced previously unrecognized transient lip and/or brow paralysis. All patients tolerated concurrent neck ultrasound and ablative fractionated CO₂ laser resurfacing well.

A Comparative Study of Five Personality Factors among Employed and Unemployed People (2015)

Article type: Original Article Background: Professional identity is a part of human identity and career has a beneficial impact on psychological health. The importance of personality in job achievement has also been increasingly concerned in economics. Objective: To compare the Big Five personality factors between employed and unemployed persons. Materials and Methods: This study was an applied cross sectional analytic descriptive research of a comparative type which was conducted from January 2012 to March 2012. The sample size was thirty in each group of employed and unemployed subjects, chosen randomly from male population of a city in the North of Iran with purposive sampling method. Age and education level of subjects were controlled according to labor market conditions. For collecting data, the NEO inventory was used; five factors of personality can be assessed by which. The data were analyzed by SPSS software version 19 through descriptive and inferential statistics using independent t-test. Results: A total of thirty employed and 30 unemployed men in the age range of 20-50 years participated in the study. The neuroticism score was higher in unemployed persons (p = 0.001). The openness score resulted in no significant difference between employed and unemployed people (p = 0.96). The scores of extroversion, agreeableness and conscientiousness were significantly higher among employed people rather the unemployed ones (p = 0.01, 0.001 and 0.01, respectively). Conclusion: Personality traits except openness have significant relationship with employment, neuroticism may have a negative relationship, and the other personality traits maybe in the positive relationships with employment.

Bone Window Computed Tomography for Detection of Dural Defect Associated with Cervical Ossified Posterior Longitudinal Ligament (1997)

Anterior decompression of a cervical ossified posterior longitudinal ligament (OPLL) which involves the dura mater occasionally results in a postoperative cerebrospinal fluid fistula. Bone window computed tomography (CT) was carried out to detect dural defects in 21 patients with cervical OPLL. Twelve of 21 patients had double-layer OPLL, and nine had single-layer OPLL. Dural defects were present in 10 of the 12 patients with double-layer OPLL compared with only one of the nine patients with single-layer OPLL. In addition, greater stenosis of the spinal canal by the OPLL was also associated with dural defect. Preoperative bone window CT can indicate likely locations of dural defect in patients with OPLL.
Designing Studies Acceptable for Abstraction and Inclusion in Evidence-Based Laboratory Practice Guidelines (2018)

Expansion of technologies, changing infrastructure, and dwindling resources have produced the need for health care reform and changes in clinical laboratories. The health care model will have to shift increasingly from a fee-for-service model to a value-based model. Laboratories will have to focus more on evidence-based outcome studies evaluating the effects of their preanalytical and postanalytical practices on real patient outcomes. Although well-designed clinical trials and multicenter studies are needed to determine the effects of laboratory processes on outcomes, there has been concern that too few well-designed studies have been published. To help improve the quality of study design and to facilitate reporting transparency, several method statements have been developed. The Standards for Reporting of Diagnostic Accuracy Studies (STARD) initiative was recently updated, listing 30 items deemed crucial for transparent reporting of studies, thereby allowing the creation of a robust database for clinical practice guidelines. Three methods describing the assessment of the quality of data on which to base recommendations for such guidelines are also available. Close attention must be given to study design so that parameters ensuring study quality are met, thereby allowing inclusion of the study data in the formulation of evidence-based laboratory best practices guidelines.
Environment Perception in the Presence of Kinesthetic or Tactile Guidance Virtual Fixtures (2015)

During multi-lateral collaborative teleoperation, where multiple human or autonomous agents share control of a teleoperation system, it is important to be able to convey individual user intent. One option for conveying the actions and intent of users or autonomous agents is to provide force guidance from one user to another. Under this paradigm, forces would be transmitted from one user to another in order to guide motions and actions. However, the use of force guidance to convey intent can mask environmental force feedback. In this paper we explore the possibility of using tactile feedback, in particular skin deformation feedback, skin deformation feedback to convey collaborative intent while preserving environmental force perception. An experiment was performed to test the ability of participants to use force guidance and skin deformation guidance to follow a path while interacting with a virtual environment. In addition, we tested the ability of participants to discriminate virtual environment stiffness when receiving either force guidance or skin deformation guidance. We found that skin deformation guidance resulted in a reduction of path-following accuracy, but increased the ability to discriminate environment stiffness when compared with force feedback guidance.
Recovery of Lactic Acid by Batch Distillation with Chemical Reactions Using Ion Exchange Resin. (1999)

Batch distillation of lactic acid with the simultaneous reactions was studied. Lactic acid was reacted with methanol, and methyl lactate was produced by the esterification reaction. The volatile methyl lactate was distilled simultaneously with the hydrolysis reaction into lactic acid. To recover pure lactic acid through two reactions and distillation, batch distillation system consisted of two condensers, feed vessel, and reboiler was studied. For both reactions of esterification and hydrolysis, the acidic cation exchange resin was used as a solid catalyst. As the concentration of catalyst increased, the yield of recovered lactic acid was increased. As the feed concentration of lactic acid and the reactant molar ratio in the esterification reaction decreased, the recovery yield of lactic acid was increased. The yield of recovered lactic acid was as high as 95%. When impure lactic acid solution obtained from bacterial fermentation was used as feed, highly pure lactic acid solution was obtained with yield of 92% in reboiler.
ERP Evidence for a Shifting Attention Deficit in Patients with Damage to the Cerebellum (1994)

Abstract In a previous study, we found that patients with damage to the neocerebellum were significantly impaired in the ability to rapidly shift their attention between ongoing sequences of auditory and visual stimuli (Akshoomoff & Courchesne, 1992). In the present study, young patients with damage to the neoccrebelluni were found to be impaired in rapidly shifting their mention between visual stimuli that occurred within a single location. Event-related potentials recorded during the shifting attention experiment suggested that this reflects a deficit in the. covert ability to selectively activate and deactivate attention. These results lend Further support to the hypothesis that the neocerebellum plays a role in the ability to rapidly shift attention.
Resonance Energy Transfer between Rhodamine Molecules Adsorbed on Layered Silicate Particles (2009)

Förster resonance energy transfer (FRET) from rhodamine 123 (Rh123; the energy donor (ED)) to rhodamine 610 (Rh610; the energy acceptor (EA)) adsorbed on the surface of synthetic saponite (SAP) was investigated. Experiments were performed with colloidal dispersions and thin solid films. In the colloidal systems, we observed efficient FRET leading to emission from the EA that was dependent on the molar ratio of the dyes. Self-quenching partially contributed to the relaxation of rhodamine molecules. Competitive adsorption of the dyes on SAP significantly influenced FRET under specific conditions. Adsorbed Rh610 was easily replaced by Rh123, especially at high dye loadings, and by surfactant dodecyltrimethylammonium (C12TMA) cations, especially at high surfactant concentrations. Rh610 forms zwitterions via the hydrolysis of carboxyl groups. The presence of the anionic group in the Rh610 molecule contributes to the repulsion between the dye molecules and SAP colloid particles and to lower adsorption of the dye. With a large excess of the ED, very efficient FRET was observed for films with SAP, C12TMA cations, Rh123, and Rh610. The main role of the inorganic SAP template is to bring the interacting dye molecules close together but still prevent fluorescence quenching caused by dye molecular aggregation.
Genipin-Crosslinked Fibrin Hydrogels Modified With Collagen or Fibronectin as an Annulus Fibrosus Sealant (2012)

Low back pain (LBP) affects 80% of all adults at some point in their lives [1], and is often associated with intervertebral disc (IVD) degeneration, therefore, restorative solutions are of high importance. The IVD is composed of an outer ring of annulus fibrosus (AF) containing the pressurized nucleus pulposus (NP) center. NP replacement approaches and IVD procedures such as discectomy or discography involve rupture of the AF tissue for diagnosis or repair purposes. Even small defects to the outer AF can accelerate IVD degeneration [2]. Current closure techniques are limited to sutures and offer little in the way of tissue replacement or mechanical restoration of the AF [3]. A genipin crosslinked fibrin hydrogel offers some promise as an adhesive AF sealant [4]. Fibrin is FDA approved and genipin is a plant based chemical crosslinker with low cytotoxicity used with a variety of materials including fibrin for articular cartilage engineering [5]. Genipin crosslinked fibrin is a tunable material with comparable mechanical properties to native AF tissue and although cells remained viable on the gel, the relatively slow proliferation and presence of abnormal cells with rounded morphology motivated further optimization. To improve cytomorphology, key extracellular matrix proteins, collagen and fibronectin, were added to the formulation. It was hypothesized that the addition of these proteins would maintain the mechanical properties of this gel while improving cell morphology and viability. Several additional analyses were included to further characterize this gel including push-out strength, degradation and contraction tests.
Hydrogenated amorphous silicon oxide containing a microcrystalline silicon phase and usage as an intermediate reflector in thin-film silicon solar cells (2011)

To further improve the stability of amorphous/microcrystalline silicon (a-Si:H/μc-Si:H) tandem solar cells, it is important to reduce the thickness of the a-Si:H top cell. This can be achieved by introduction of an intermediate reflector between the a-Si:H top and the μc-Si:H bottom cell which reflects light back into the a-Si:H cell and thus, increases its photocurrent at possibly reduced thickness. Microcrystalline silicon oxide (μc-SiOx:H) is used for this purpose and the trade-off between the material’s optical, electrical and structural properties is studied in detail. The material is prepared with plasma enhanced chemical vapor deposition from gas mixtures of silane, carbon dioxide and hydrogen. Phosphorus doping is used to make the material highly conductive n-type. Intermediate reflectors with different optical and electrical properties are then built into tandem solar cells as part of the inner n/p-recombination junction. The quantum efficiency and the reflectance of these solar cells are evaluated to find optical gains and losses due to the intermediate reflector. Suitable intermediate reflectors result in a considerable increase in the top cell current density which allows a reduction of the a-Si:H top cell thickness of about 40% for a tandem cell while keeping the current density of the device constant.
Utilizing Furfural-Based Bifuran Diester as Monomer and Comonomer for High-Performance Bioplastics: Properties of Poly(butylene furanoate), Poly(butylene bifuranoate), and Their Copolyesters (2019)

Two homopolyesters and a series of novel random copolyesters were synthesized from two bio-based diacid esters, dimethyl 2,5-furandicarboxylate, a well-known renewable monomer, and dimethyl 2,2'-bifuran-5,5'-dicarboxylate, a more uncommon diacid based on biochemical furfural. Compared to homopolyesters poly(butylene furanoate) (PBF) and poly(butylene bifuranoate) (PBBf), their random copolyesters differed dramatically in that their melting temperatures were either lowered significantly or they showed no crystallinity at all. However, the thermal stabilities of the homopolyesters and the copolyesters were comparable. Based on tensile tests from amorphous film specimens, it was concluded that the elastic moduli, tensile strengths, and elongation at break values for all copolyesters were similar as well, irrespective of the furan:bifuran molar ratio. Tensile moduli of approximately 2 GPa and tensile strengths up to 66 MPa were observed for amorphous film specimens prepared from the copolyesters. However, copolymerizing bifuran units into PBF allowed the glass transition temperature to be increased by increasing the amount of bifuran units. Besides enhancing the glass transition temperatures, the bifuran units also conferred the copolyesters with significant UV absorbance. This combined with the highly amorphous nature of the copolyesters allowed them to be melt-pressed into highly transparent films with very low ultraviolet light transmission. It was also found that furan-bifuran copolyesters could be as effective, or better, oxygen barrier materials as neat PBF or PBBf, which themselves were found superior to common barrier polyesters such as PET.
A fin type of underwater microrobot with multi DOF (2003)

This paper describes the new structure and motion mechanism of an underwater microrobot using ICPF actuator, and discusses the swimming possibility of the microrobot in water. Characteristic of the underwater microrobot is measured by changing the frequency and the amplitude of input voltage. The experimental results indicate that the swimming speed of proposed underwater micro robot can be controlled by changing the frequency of input voltage; the moving direction (upward or downward) can be controlled by changing the amplitude and the frequency of input voltage.
Agouti Antagonism of Melanocortin-4 Receptor: Greater Effect with Desacetyl-α-Melanocyte-Stimulating Hormone (MSH) than withα -MSH (1999)

Desacetyl-alpha-MSH is more abundant than alpha-MSH in the brain, the fetus, human blood, and amniotic fluid, but there is little information on its ability to interact with melanocortin receptors. The aim of this study is to compare and contrast the ability of desacetyl-alpha-MSH and alpha-MSH to couple melanocortin receptors stably expressed in HEK293 cells, to the protein kinase A (PKA) signaling pathway. Desacetyl-alpha-MSH activated mouse MC1, MC3, MC4 and MC5 receptors with EC50s = 0.13, 0.96, 0.53, and 0.84 nM, and alpha-MSH activated these receptors with EC50s = 0.17, 0.88, 1.05, and 1.34 nM, respectively. Mouse agouti protein competitively antagonized alpha-MSH and desacetyl-alpha-MSH coupling to the MC1-R similarly. In contrast, mouse agouti protein antagonized desacetyl-alpha-MSH much more effectively and potently than alpha-MSH coupling the MC4-R to the PKA signaling pathway. Furthermore, mouse agouti protein (10 nM) significantly reduced (1.4-fold) the maximum response of mMC4-R to desacetyl-alpha-MSH and 100 nM mouse agouti significantly increased (4.8-fold) the EC50. Minimal antagonism of alpha-MSH coupling mMC4-R to the PKA signaling pathway was observed with 10 nM mouse agouti, whereas both 50 and 100 nM mouse agouti appeared to reduce the maximum reponse (1.1- and 1.3-fold, respectively) and increase the EC50 (2.5- and 3.4-fold respectively). Mouse agouti protein did not significantly antagonize either alpha-MSH or desacetyl-alpha-MSH coupling mouse MC3 and MC5 receptors. Understanding the similarities and differences in activation of melanocortin receptors by desacetyl-alpha-MSH and alpha-MSH will contribute to delineating the functional roles for these endogenous melanocortin peptides.
Determination of initial configuration for LVQ by using CNN (2005)

A method for determining the initial configuration for the LVQ is proposed. It is based on the condensed nearest neighbor (CNN) rule followed by the K-means clustering method. Experiments show that the proposed method is generally better than the conventional ones which use k-NN or the K-means. And it is also shown that the performance of the CNN is improved by applying the LVQ as a post processing.
Asymmetric Molecular Dynamics and Anisotropic Phase Separation in the Cocrystal of the Crystalline/Crystalline Polymer Blend (2022)

Semicrystalline polymers are categorized as either mobile or fixed crystals, depending on chain mobility in the crystalline region. In this work, we investigate molecular dynamics and phase structure in the cocrystal consisting of fixed and mobile polymer crystals by solid-state (ss) nuclear magnetic resonance (NMR) spectroscopy. It is demonstrated that (i) the mobile component begins large amplitude motions associated with crystal-crystal transition, while fixed ones keep their rigidity in the cocrystal, and (ii) asymmetric molecular dynamics leads to nanosegregations into mobile- and fixed-rich domains in the cocrystal below the melting temperature (<i>T</i><sub>m</sub>). The observed phase separation induced by asymmetric molecular dynamics is similar to the phase separation of the miscible amorphous polymer blend; however, it is limited to two dimensions due to the parallel packing of the stems inside the cocrystal, as well as chain connectivity at the crystalline-amorphous boundary.
Use of Productivity and Financial Indicators for Monitoring Performance in Academic Radiology Departments: U.S. Nationwide Survey (2005)

Academic radiology departments across the United States do not use a standardized set of productivity and financial indicators to measure departmental performance. Examination volume is the most frequently used productivity indicator, whereas general expenses are commonly used as indicators of financial status.
Localized Search Cues in Corn Roots for Western Corn Rootworm (Coleoptera: Chrysomelidae) Larvae (2009)

Cues that elicit a characteristic localized search behavior by neonate larvae of the western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), were extracted from living corn, Zea mays L., roots with acetone. Larvae were exposed to corn roots or to an acetone extract of corn roots and then transferred into a bioassay arena where their movements were tracked and recorded. After a 5-min exposure to live corn roots, larvae produced highly convoluted tracks that were indicative of a localized search behavior, and these distinctive tracks were also produced by larvae exposed to an acetone extract of corn roots. Larvae exposed to a filter paper control moved in relatively straight paths that were indicative of ranging behavior. Larval tracks were recorded by means of a videocamera and tracking software, and four parameters of movement were used to quantify the tracks: mean turn angle, mean meander, total distance, and maximum distance from origin. For every parameter measured, tracks resulting from exposure to the control were significantly different from tracks resulting from exposure to live corn roots and to all doses of the corn root extract. In a separate experiment, larvae exposed to corn root pieces or corn root juice exhibited the localized search behavior, but larvae exposed to oat root pieces and oat root juice (nonhost) exhibited ranging behavior.
