Optimizing Network Congestion Control for High-Performance Remote Direct Memory Access Transfers
Pages: 1–9
Abstract
Citation
—High-performance interconnects need congestion control to deal with traffic bursts. In this paper, we propose ACCurate, a congestion control protocol that assigns exact maxmin fair rates to flows, without relying on costly per-flow state inside the network. ACCurate keeps the backlogs outside of the network, protects innocent flows, and promptly recovers the flows’ rates after congestive episodes. Comparisons with TCP and PAUSE-only RDMA under datacenter-resembling workloads further show that ACCurate provides up to 10x faster flow completion times. ACCurate relies on simple hardware that can be readily implemented inside switches. In our implementation, the additional circuitry needed in a 16×16 switch occupies less than 2% of FPGA resources.

Comparative Analyses of Foeniculum vulgare: Antibacterial Outcomes and Phytochemical Profiling of Essential Oil.
Pages: 10–14
Abstract
Citation
Medicinal plants are considered modern resources for producing agents that could act as alternatives to antibiotics in demeanor of antibiotic-resistant bacteria. The aim of the study was to evaluate the chemical composition and antibacterial activities of essential oil of Foeniculum vulgare (FV) against Pseudomonas aeruginosa and Bacillus subtilis. Gas chromatography mass spectrometry was done to specify chemical composion. As a screen test to detect antibacterial properties of the essential oil, agar disk and agar well diffusion methods were employed. Macrobroth tube test was performed to determinate MIC. The results indicated that the most substance found in FV essential oil was Trans-anethole (47.41 %), also the essential oil of FV with 0.007 g/ml concentration has prevented P. aeruginosa and with 0.002 g/ml concentration has prevented B. subtilis from the growth. Thus, the research represents the antibacterial effects of the medical herb on test P. aeruginosa and B. subtilis. We believe that the article provide support to the antibacterial properties of the essential oil. The results indicate the fact that the essential oil from the plant can be useful as medicinal or preservatives composition.

Evaluating Antimicrobial Potentials of Herbal Remedies in Urinary Tract Infections
Pages: 15–21
Abstract
Citation
Medicinal plants are part and parcel of human society to combat diseases from the dawn of civilization. According to World Health Organization (WHO), about 80% of the world population rely chiefly on plant based traditional medicine specially for their primary health care needs and there has been a worldwide move towards the use of traditional medicines due to concerns over the more invasive, expensive and potentially toxic main stream practices. This review gives a bird’s eye view on the updated information on urinary tract infections (UTIs), different categories of urologic herbs, historical use and modern scientific investigations on some important urologic herbs, clinical studies, some isolated chemical compounds and their possible side effects.

Energy-Efficient Management Paradigms for Smart Buildings and Infrastructure
Pages: 22–38
Abstract
Citation
The incremented popularity of Internet of Things (IoT), thanks to improvements both in hardware and software of sensors over the last years, enables the possibility to monitor and gather any kind of data. Additionally, the arrangement of heterogeneous sensors, capable of perceiving information about their surroundings, into a rich Wireless Sensor Network (WSN), allows the appearance of complex systems in which resources are managed more efficiently. Smart cities, buildings, parkings, emergency services are appearing, where control over energy consumption and better sustainability are coupled with an improvement of the comfort of occupants. In this paper, we address the problem of energy optimization in smart buildings, considering both the planning and operational aspects. Specifically, the first aim is to propose an optimal deployment of the WSN inside a building. For this, we present a model able to identify the optimal locations for different types of sensors and gateways, by optimizing energy consumption while fulfilling connectivity, resource, protection, and clustering coverage constraints. Once the IoT system is deployed, we address the problem of how the building actually functions, according to the behaviour of the occupants. In particular, we propose a Building Management System (BMS) capable of efficiently and automatically manage the building elements using human behavioural models, thus lowering the overall building energy consumption whilst maintaining acceptable levels of comfort.

Reframing Reflexivity in Scientific Inquiry
Pages: 39–44
Abstract
Citation
T he value of reflexivity has repeatedly been mobilised in claims for Social Sciences and Humanities (SSH) involvement in Science, Technology, Engineering and Mathematics (STEM) research. In short (if not in caricature), the policy narrative goes like this: Scientists, scientific practices, the governance of science and indeed modern society should become more reflective/reflexive. This can be achieved by involving SSH, which are inherently reflexive. In this paper, I will follow this narrative from the “Ethical, Legal and Social Implications” (ELSI)/ “Ethical, Legal and Social Aspects of bio-, neuro-, and nanotechnology (ELSA) policies and practices of the 1990s and 2000s, to the concept of “Responsible Research and Innovation” (RRI) and the “need to integrate” SSH with STEM to address societal challenges in Horizon 2020. Drawing upon my experience as an SSH practitioner in ELSA, RRI and societal challenges-focused interdisciplinary collaborations, I shall propose two lessons learnt. One key lesson is the need to go beyond the simple policy narrative “SSH makes science more reflexive” and the many disappointments that it invariably produces. The other key lesson is the need to go beyond simple dichotomies between SSH research and scholarship on one hand and non-SSH research on the other in order to look for meaningful collaborations.

Novel Antifungal Agents for Pityriasis Versicolor: A Comparative Study on Ivermectin and Calvatia Craniiformis
Pages: 45–53
Abstract
Citation
Objectives: isolation of Malassezia furfur from pityriasis versicolor (PV) patients; in vitro evaluation of ivermectin and Calvatia craniiformis antifungal activity as novel agents for treatment; finally evaluation of age, gender, contact with animals and marital status as risk factors for M. furfur infections. Methods: Sixty PV patients were included. M furfur isolated on Sabouraud dextrose agar. ivermectin aqueous solutions (0.5%), (1%) and (2%); C craniiformis alcoholic extracts ( 50mg, 100mg, 200mg, 400mg, 600mg, 800mg and 1 gm) were used to determine their novel antifungal activity against M furfur in vitro using broth dilution susceptibility test. Results: The majority of patients (61.7%) in age group (27-32) years followed by (21-26) years. Males : females represent (83.33%: 16.67%) . Significant difference was reported among patients in age, gender, marital status and anatomic location of body area infected with M furfur. Age has no significant correlation with other proposed risk factors of M.furfur infection. Gender significantly correlated with contact with dogs and birds as well as marital status ( p value =0.000). Marital status significantly correlated with contact with animals(dogs and birds, p value =0.000);infected area of the body ( p value =0.000).Contact with dogs and birds significantly correlated with anatomic location of infected area of the body ( p value =0.000). A total of (75%) of patients respond to treatment with (2 %)ivermectin aqueous solution, the meantime for clearance was 23.5 days. A total of (90 %) of patients respond to treatment with alcoholic extract of C. craniiformis (1000 mg), meantime for clearance was 24days. Significant difference in time of complete curing reported between groups (p<0.05). Significant difference was detected between the following C. craniiformis concentrations: 100mg and 200 mg; 200 mg and 400 mg; 400 mg and 600 mg; 100mg and 1000 mg; 800 mg and 1000 mg; 400 mg and 1000 mg. Significant difference between 1% and 2% as well as 0.5% and 2% Ivermectin was determined. Conclusions: M. furfur considered an important etiology for PV. Alcoholic extract of C. craniiformis (1000 mg), and (2%) ivermectin aqueous solution, significantly inhibit the in vitro growth of M. furfur. The effect was proportionally associated with concentration. The meantime of clearance for clinical lesions, using these agents was shorter than fluconazole and hence can be used as a novel topical antifungal agent for treatment of PV associated M. furfur infections. The main risk factor for PV associated M. furfur infection was direct contact with dogs and birds while infection indirectly affected by gender .The main affected sites were neck and shoulder together, neck and trunk respectively.

Advancements in Topological Photonics for Enhanced Optical Communications and Quantum Computing Paradigms
Pages: 54–65
Abstract
Citation
: The ongoing digital transformation is bringing a pervasive diffusion of ultra-broadband, fixed-mobile connectivity, the deployment of cloud-native Fifth Generation (5G) infrastructures, edge and fog computing and a wide adoption of artificial intelligence. This transformation will have far-reaching techno-economic impacts on our society and industry. Nevertheless, this transformation is still laying its foundation in electronics and the impending end of Moore’s law. Therefore, looking at the future, a rethinking of the ways of doing computations and communications has already started. An extended adoption of quantum technologies is one possible direction of innovation. As a matter of fact, a first quantum revolution, started decades ago, has already brought quantum technologies into our daily lives. Indeed, today, a second revolution seems to be underway, exploiting advancements in the ability to detect and manipulate single quantum objects (e.g., photons, electrons, atoms and molecules). Among the different technological approaches, topological photonics is a rapidly growing field of innovation. Drawing inspiration from the discovery of the quantum Hall effect and topological insulators in condensed matter, recent advances in topological photonics hold a promising opportunity for optical networking and quantum computing applications.

Sustainable Construction: Utilizing Industrial Byproducts to Reduce Carbon Footprint in Concrete Production.
Pages: 66–70
Abstract
Citation
Cement is one of the most extensive materials used in the construction industry. It was estimated that the production of 1 ton of cement produces 1 ton of carbon dioxide which results in increase in the emission of green-house gases. With the advancements in research, the utilization of mineral admixtures like fly ash, ground granulated blast furnace slag, silica fume, metakaolin, sugar cane bagasse ash, rice husk ash are reduces the use of cement and also the effective utilization of waste byproducts in which the disposal is a major problem in the regard of environmental pollution. According to considering all the above issues a research work was done to study the effect of binary blending of mineral admixtures on the fresh & hardened properties M35 grade concrete were studied and reported. Also an analytical equation was proposed between compressive and flexural strength of concrete on par with IS:456-2000 and a good agreement was found between them.
