Multi-Factor Performance Comparison of Amazon Web Services Elastic Compute Cluster and Google Cloud Platform Compute Engine

Cloud computing has rapidly become a viable competitor to on-premise infrastructure from both management and cost perspectives. This research provides insight into cluster computing performance and variability in cloud-provisioned infrastructure from two popular public cloud providers. A comparative examination of the two cloud platforms using synthetic benchmarks is provided. In this article, we compared the performance of Amazon Web Services Elastic Compute Cluster (EC2) to the Google Cloud Platform (GCP) Compute Engine using three benchmarks: STREAM, IOR, and NPB-EP. Experiments were conducted on clusters with increasing nodes from one to eight. We also performed experiments over the course of two weeks where benchmarks were run at similar times. The benchmarks provided performance metrics for bandwidth (STREAM), read and write performance (IOR), and operations per second (NPB-EP). We found that EC2 outperformed GCP for bandwidth. Both provided good scalability and reliability for bandwidth with GCP showing a slight deviation during the two-week trial. GCP outperformed EC2 in both the read and write tests (IOR) as well as the operations per second test. However, GCP was extremely variable during the read and write tests over the two-week trial. Overall, each platform excelled in different benchmarks and we found EC2 to be more reliable in general.

Digital platforms as means of political propaganda: The case of the protest Against dictatorship fake Facebook page

Growing distrust in the mainstream media has led to rising importance of cyberspace in creation of the public sphere. This is especially visible in networked autocracies, regimes that have established firm control over mainstream media, but who have also developed effective strategies and techniques to fight against political opponents on digital platforms. In the networked autocracies one can observe a development of specific type of political propaganda that can be characterized as computational propaganda. This type of propaganda is created with the help of digital platforms, political bots and the Internet of Things. The basic role of computational propaganda is not based on delivering of a positive image of the one in whose name it is being implemented, but pollution and polarization of public spaces of the Internet, with the goal to discourage as many people as possible from online political activism. Serbia is one of the countries with a highly developed computational propaganda, whether we are talking about the number of people who perform this type of propaganda in the name of the ruling majority, or we are talking about the scope of their actions. One of examples of their internet operations was launching a fake Facebook page of the Protest against the dictatorship, with the aim of confusing supporters of this protest. Our empirical study has shown that cyber troupes of the ruling majority, known as bots, have been very successful in conducting their online campaign which contributed to the end of one of the greatest anti-government protests in the post-Milosevic era.

Tropane alkaloids of Atropa belladonna L. and Atropa acuminata Royle ex Miers plants

The purpose of the present study was to determine the tropane alkaloid content in different parts of the wild and cultivated Atropa belladonna L. and wild Atropa acuminata Royle ex Miers in Iran. Determination of alkaloids was performed by high-performance liquid chromatography (HPLC) method. Samples were extracted with chloroform- methanol- cc. ammonia 15:15:1(v/v/v). HPLC separation was performed on two C8 columns. An isocratic mobile phase of acetonitrile- 50 mM phosphate buffer (pH 2.95) 10:90 and 20:80(v/v) was used. Peaks were identified by standards and diode-array detection. Scopolamine and atropine were determined by external method at 210 nm. The total alkaloid content of the A. belladonna L. of sari-kiassar road was determined by a HPLC method to be 2.88% for the leaves and 8.06% for the roots and 1.42% for the stem. The total alkaloid content of the cultivated A. belladonna L. was 1.76% for the leaves, 3.3% for the roots, 1.42% for the stem and 4.82% for the seeds. Total alkaloid content of the leaves of A. acuminata was 5.88%. In all samples the percentage of atropine was higher than scopolamine. The results showed that A. belladonna and A. acuminata constitutes the major storage site and had the highest amount of these alkaloids. These alkaloids may be transported to other plant organs providing potential deterrent and antimicrobial activities.

The Effect of Intra-Muscular Injections of Alpha-tocopherol on the Activity of Phospho- Fructokinase in the Slow- and Fast-Twitch Skeletal Muscles of Metabolic Stress-Induced and Malnourished Rats

It was been hypothesized that critical illness will change the activity of phospho-fructokinase (PFK) and that intramuscular (i.m) injections of the antioxidant α-tocopherol would protect this rate- limiting enzyme of glycolysis in the slow-twitch soleus and in the fast-twitch extensor digitorum longus (EDL) muscles of metabolically-stressed and malnourished rats. Twenty eight male Wistar rats were divided into four groups: controls (CNs), zymosan-injected (ZY), α- tocopherol-injected (ZYE), and pair-fed (PF). Rats were fed Osmolite-HN, and were sacrificed on day three. PFK activity was measured in EDL and soleus muscles using a fluorometric assay, and was found to be significantly lower in both the soleus and EDL of ZY rats. The PFK activity in the EDL of ZYE rats was comparable to the PFK of PF rats and was significantly higher than ZY rats on day three. Glycolysis in the slow- and fast-twitch muscle of ZY rats is adversely affected, and three days of i.m injections of α-tocopherol significantly (p<0.05) protected PFK activity, in fast-twitch but not in slow- twitch muscles.

NN2CAM: Automated Neural Network Mapping for Multi-Precision Edge Processing on FPGA-Based Cameras

The record-breaking achievements of deep neural networks (DNNs) in image classification and detection tasks resulted in a surge of new computer vision applications during the past years. However, their computational complexity is restricting their deployment to powerful stationary or complex dedicated processing hardware, limiting their use in smart edge processing applications. We propose an automated deployment framework for DNN acceleration at the edge on field-programmable gate array (FPGA)-based cameras. The framework automatically converts an arbitrary-sized and quantized trained network into an efficient streaming-processing IP block that is instantiated within a generic adapter block in the FPGA. In contrast to prior work, the accelerator is purely logic and thus supports end-to-end processing on FPGAs without on-chip microprocessors. Our mapping tool features automatic translation from a trained Caffe network, arbitrary layer-wise fixed-point precision for both weights and activations, an efficient XNOR implementation for fully binary layers as well as a balancing mechanism for effective allocation of computational resources in the streaming dataflow. To present the performance of the system we employ this tool to implement two CNN edge processing networks on an FPGA-based high-speed camera with various precision settings showing computational throughputs of up to 337GOPS in low-latency streaming mode (no batching), running entirely on the camera.

Language development is one of the many areas of development that needs to be addressed in kindergarten. Language as a systematic and orderly system of pronunciation, ideas and emotions used for speaking, listening, reading and writing to communicate with other people. This research focuses on analysis related to early childhood language development, through the stages of development, the factors that influence children's language development, as well as indicators of children's language development and various theories of language development. The purpose of this research is to analyze matters related to children's normal development, this is because various problems often arise that children experience when they struggle with acquiring good language. The method used in this research is a qualitative method in the form of library research. The results of this research concluded that it is important to understand children's language development because the development of young children goes through 4 stages, namely pre-imgistic, single words, two-word sentences, and short sentences. Language and language development are important aspects of life, related to child development issues, the role of parents and teachers is an important factor in language development, because they must be good at stimulating children's language intelligence.

Antibodies to Malaria Vaccine Candidates Pvs25 and Pvs28 Completely Block the Ability of<i>Plasmodium vivax</i>To Infect Mosquitoes

ABSTRACT Transmission-blocking vaccines are one strategy for controlling malaria, whereby sexual-stage parasites are inhibited from infecting mosquitoes by human antibodies. To evaluate whether the recently cloned Plasmodium vivax proteins Pvs25 and Pvs28 are candidates for a transmission-blocking vaccine, the molecules were expressed in yeast as secreted recombinant proteins. Mice vaccinated with these proteins adsorbed to aluminum hydroxide developed strong antibody responses against the immunogens, although for Pvs28, this response was genetically restricted. Antisera against both recombinant Pvs25 and Pvs28 recognized the corresponding molecules expressed by cultured sexual-stage parasites isolated from patients with P. vivax malaria. The development of malaria parasites in mosquitoes was completely inhibited when these antisera were ingested with the infected blood meal. Pvs25 and Pvs28, expressed in Saccharomyces cerevisiae , are as yet the only fully characterized transmission-blocking vaccine candidates against P. vivax that induce such a potent antiparasite response.

SH057577.07FU

UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

Exploring the nexus between microlevel and contextual influencers on women leaders’ paradox mindset

Purpose Women leaders struggle with the persistent paradoxical expectations. Literature suggests that a paradox mindset helps to leverage these tensions. This study aims to understand the nexus between the microfoundations of individual women leaders’ experiences, their responses and the organisational context, which enables or hinders their paradox mindset. Design/methodology/approach This study adopted a qualitative approach by conducting semistructured interviews with 14 women, all senior leaders in corporate South Africa. Findings The results reveal the interaction in the nexus between, firstly, women leaders’ authenticity and awareness as key anchors that enable them to adopt a paradox mindset and, secondly, the organisation’s role in creating hindrances or opportunities to leverage tensions. Women leaders in our sample applied one of two strategies: they either adapted to the environment or curated a subenvironment. This study shows that, if done authentically, through her own agency, a woman can influence interactions that make it easier to manage tensions within her environment, especially those created by negative performance evaluation because of unconscious institutional gender bias. Research limitations/implications The extent to which the findings of this research can be generalised is constrained by the selected research context. Originality/value This research contributes to the literature on paradox theory by revealing organisational contextual influencers, such as institutional bias in negative performance evaluation, which hinders a woman leader’s opportunity to be hired or promoted. These organisational influences also interact with women leaders’ ability to embrace paradox and internally leverage agentic and communal tensions.

Histamine In Pig Platelet Dense Granules

In the course of high resolution nuclear magnetic resonance (n.m.r.) studies of dense granule storage complexes, an amine with two aromatic protons was observed in a proton n.m.r. spectrum of dense granules isolated from pig platelets. This amine was identified as histamine by the exact coincidence of the n.m.r. peaks of added histamine with the unknown peaks in the extract. The pH dependence of chemical shifts, paper chromatography and flurometric analysis after coupling with o-phthalaldehyde confirmed the identification. The concentration of histamine in isolated dense granules was about 700 nmol/mg of protein (n=3) or 1.6 times that of serotonin. In intact platelets, the histamine content was 11 nmol/mg compared to 7 nmol/mg of serotonin. The addition of 1 unit/ml of thrombin to suspensions of washed pig platelets resulted in the secretion of more than 90% of the histamine under conditions in which only 3.8% of thelactate dehydrogenase appeared extracellularly. These findings indicate that histamine is a major constituent of dense granules in pig platelets which can be released during hemostasis and thrombosis and may exert its pharmacological effects under these conditions.

Using clouds to provide grids HigherLevels of abstraction and explicit support for usage models. internal-pdf:// cloud-grid-saga-3552647680/cloud-grid-saga.pdf

Abstract—Grids in their current form of deployment and implementation have not been as successful as hoped in engendering distributed applications. Amongst other reasons, the level of detail that needs to be controlled for the successful development and deployment of applications remains too high. We argue that there is a need for higher levels of abstractions for current Grids. By introducing the relevant terminology, we try to understand Grids and Clouds as systems; we find this leads to a natural role for the concept of Affinity, and argue that this is a missing element in current Grids. Providing these affinities and higher-level abstractions is consistent with the common concepts of Clouds. Thus this paper establishes how Clouds can be viewed as a logical and next higher-level abstraction from Grids.

California Citrus Thrips Small Plot Trial, 1996

Abstract Insecticides were evaluated spring, 1996 in Field 12 (26 year-old ‘Atwood’ navel oranges) at the University of California’s Lindcove Field Station near Exeter, CA for control of citrus thrips. Pesticides were applied with a Bean hand-sprayer at 500 psi, outside coverage, approximately 200 gpa. Field 12 was divided into 4 contiguous blocks of 88-92 trees (22-23 replicates) and 22 treatments were applied with one replicate of each treatment assigned randomly to each block except extra replicates were assigned to the untreated check: each replicate consisted of four contiguous trees (except 2 replicates which had only 3 trees). Citrus thrips fruit scarring was evaluated early November. 1995 on all fruit on the exterior of data trees from knee to eye level. Scarring was rated as: (a) none, (b) slight (any citrus thrips scarring), or (c) severe (complete ring scar or extensive surface scarring at a level that would cause downgrading of fruit in a commercial operation). Approximately 5% severe scars are normally taken as economic scarring levels.

Spinous process wiring versus lateral mass fixation for the treatment of anterior cervical pseudarthrosis: a biomechanical comparison.

Our objective was to compare the stiffness of lateral mass screws versus two different spinous process wiring constructs in a cadaveric model of plated anterior cervical pseudoarthrosis. When treating an anterior plated pseudoarthrosis via a posterior approach, it is unclear whether the added expense, muscle exposure, and risk of lateral mass fixation are justified biomechanically versus a simpler, cheaper, and potentially less morbid wiring technique, because the presence of the anterior plate likely reduces motion over the unplated situation. Seven cadaveric cervical spines were loaded in compression, flexion, extension, lateral bending, and torsion. Each load sequence was applied to: 1) the intact spine; 2) after application of a plated ACDF construct (pACDF); and 3) after the insertion of lateral mass (LM) screws, ``modified'' triple wiring (TW), or Roger's wiring (RW), in alternating order for each specimen. For each sequence, load deformation curves and stiffness were obtained. Supplemental LM fixation significantly (p ≤ 0.05) increased stiffness versus pACDF in all six modes tested. TW significantly increased stiffness versus pACDF in compression, flexion, and torsion, but not in extension, or lateral bending. RW significantly increased stiffness versus pACDF only in axial torsion. When comparing LM to the wiring constructs, LM fixation was significantly stiffer than RW in flexion, extension, and lateral bending; LM fixation was stiffer than TW in lateral bending. LM fixation produced the stiffest overall constructs in stabilizing a plated pseudarthrosis ACDF model. It was significantly stiffer in more modes versus RW than TW.

Development Multiplex–PCR Technique for Concurrent Detection of Taxonomically Different DNA Viruses in Banana (Musa acuminata) Cv. Canvendish

<title>Abstract</title> The Banana bunchy top virus (BBTV) and Cucumber mosaic virus (CMV) pose significant threats to banana production, highlighting the need to plant virus-free specimens to maximize yield and control disease spread. Early detection is crucial, as BBTV symptoms typically appear 25 to 85 days after being transmitted by aphids (Pentalonia negronervosa). In this study, we designed multiplex PCR primers targeting key viral regions: movement protein-encoding genes (MV), replication-associated re- gion genes (RP), and coat protein genes (CP) for both BBTV and CMV. Samples were collected from various agroclimatic zones within Maharashtra’s banana-growing regions. An internal control primer was included to identify any PCR reaction failures. Our results show that multiplex PCR is a highly effective method for virus screening in bananas, reducing the occurrence of false positives often seen in single-gene PCR amplification. Based on our findings, we recommend the use of multiplex PCR markers for routine testing of virus-free banana plants to improve disease management and productivity in cavendish banana cultivation.

A Novel Web Metric For The Evaluation Of Internet Trends

Web 2.0 (social networking, blogging and online forums) can serve as a data source for social science research because it contains vast amount of information from many different users. The volume of that information has been growing at a very high rate and becoming a network of heterogeneous data; this makes things difficult to find and is therefore not almost useful. We have proposed a novel theoretical model for gathering and processing data from Web 2.0, which would reflect semantic content of web pages in better way. This article deals with the analysis part of the model and its usage for content analysis of blogs. The introductory part of the article describes methodology for the gathering and processing data from blogs. The next part of the article is focused on the evaluation and content analysis of blogs, which write about specific trend.
