An Efficient Spam Detection Technique for IoT Devices Using Machine Learning

The Internet of Things (IoT) is a group of millions of devices having sensors and actuators linked over wired or wireless channel for data transmission. IoT has grown rapidly over the past decade with more than 25 billion devices expected to be connected by 2020. The volume of data released from these devices will increase many-fold in the years to come. In addition to an increased volume, the IoT devices produces a large amount of data with a number of different modalities having varying data quality defined by its speed in terms of time and position dependency. In such an environment, machine learning (ML) algorithms can play an important role in ensuring security and authorization based on biotechnology, anomalous detection to improve the usability, and security of IoT systems. On the other hand, attackers often view learning algorithms to exploit the vulnerabilities in smart IoT-based systems. Motivated from these, in this article, we propose the security of the IoT devices by detecting spam using ML. To achieve this objective, Spam Detection in IoT using Machine Learning framework is proposed. In this framework, five ML models are evaluated using various metrics with a large collection of inputs features sets. Each model computes a spam score by considering the refined input features. This score depicts the trustworthiness of IoT device under various parameters. REFIT Smart Home data set is used for the validation of proposed technique. The results obtained proves the effectiveness of the proposed scheme in comparison to the other existing schemes.
Osteopathic Manipulation for Pubic Symphysis Dysfunction During Spontaneous Labor: A Case Study

Submit Manuscript | http://medcraveonline.com in the ligamentous tissues that the patient may not be able to overcome spontaneously [5]. Most pubic symphysis dysfunction involves a vertical shear, is minor, [6] and is easily treated with simple osteopathic manipulation techniques [7-9]. Anterior/ posterior shears are more rare, but cause much more pain and disability [10]. Additionally, significant trauma due to the shears is often in the patient history.
Rainforest-like Atmospheric Chemistry in a Polluted Megacity

Abstract. The impact of volatile organic compound (VOC) emissions to the atmosphere on the production of secondary pollutants, such as ozone and secondary organic aerosol (SOA), is mediated by the concentration of nitric oxide (NO). Polluted urban atmospheres are typically considered to be high-NO environments, while remote regions such as rainforests, with minimal anthropogenic influences, are considered to be low-NO . Policy to reduce urban air pollution is typically developed assuming that the chemistry is controlled by the high-NO regime. However, our observations from central Beijing show that this simplistic separation of regimes is flawed. Despite being in one of the largest megacities in the world, we observe significant formation of gas and aerosol phase oxidation products associated with the low-NO rainforest-like regime during the afternoon. This is caused by a surprisingly low concentration of NO, coupled with high concentrations of VOCs and of the atmospheric oxidant hydroxyl (OH). Box model calculations suggest that during the morning high-NO chemistry predominates (95 %) but in the afternoon low-NO chemistry plays a greater role (30 %). With increasing global emphasis on reducing air pollution, the modelling tools used to develop urban air quality policy need to adequately represent both high- and low-NO regimes if they are to have utility.
Diagnostic pain procedures in managing chronic pain: Relevance in today's time!

Pain is subjective in nature. Every patient describes it differently. Chronic pain is a huge burden on the society. Early diagnosis is important in preventing chronic pain. The role of diagnostic pain procedures is considered very important, especially in spine. [1] In conditions where diagnosis is in question or where treatment is not working as expected, the role of diagnostic nerve block comes into play, for example, in cases of chronic low back pain (CLBP), failed back surgery syndrome (FBSS), discogenic pain, neuropathic pain, sacroiliac (SI) joint pain, myofascial pain syndrome, atypical facial pain, and chronic headaches resistant to treatment.
A reconfigurable Bessel antenna for near‐field beam deflection

This letter presents a reconfigurable leaky‐wave antenna for near‐field beam manipulation. The proposed antenna is based on a radial waveguide and a reconfigurable capacitive sheet, which is divided into four regions. To realize the reconfigurability, PIN diodes are electrically soldered to the gap between the adjacent patches in the upper surface except for the isolation zone, where no diodes are printed. By switching the states of PIN diodes in each region by turns, wavenumbers with two different azimuths are generated, thus the near‐field beam deflection can be achieved in different regions. By using the Genetic Algorithm, the PIN diodes are optimally deployed for realizing high antenna efficiency. The simulated (measured) results show that with the implementation of the reconfigurable capacitive sheet results in a near‐field beam scanning property. The beam deflection at a tilted angle of 17.4° (16.2°) can be achieved in different regions.
Sexual Offender Treatment Effectiveness Within Cognitive-Behavioral Programs: A Meta-Analytic Investigation of General, Sexual, and Violent Recidivism

The current sexual offender literature focuses on recidivism reduction in an effort to increase public safety. While cognitive-behavioral therapy (CBT) programs are considered a mainstream treatment method, it is essential to study recidivism as an indicator of treatment effectiveness. This meta-analysis examines research published since 1970 to determine the overall effectiveness of treatments in reducing recidivism among adult male sexual offenders. Decade of implementation and CBT treatment features are also assessed as moderator variables. The results from the 25 studies identified were converted into 42 weighted effect sizes utilizing a random-effects model. Significant overall effect sizes were found for sexual and violent/combination recidivism; however, multiple indices indicate heterogeneity in the effect sizes. Significant differences were found in the overall effectiveness of the treatments by decade, and the treatments delivered during the 1990s were found to be related to lower levels of sexual and violent/combination recidivism.
Sodium alginate nanoparticles as a new transdermal vehicle of glucosamine sulfate for treatment of osteoarthritis

Abstract Glucosamine sulfate (GS) has been used orally for the treatment of osteoarthritis (OA). However, it may be susceptible to the liver first pass phenomenon, which greatly affects its bioavailability, in addition to its side effects on the gastrointestinal tract. Alginate nanoparticles (Alg NPs) were investigated as a new drug carrier for transdermal delivery of GS to improve its effectiveness and reduce side effects. GS-Alg NPs were characterized by encapsulation efficiency, NP yield, particle size and surface charge properties. The in vitro release studies of GS and the ex vivo permeability through rat skin were determined using a UV-Vis spectrophotometer. GS-Alg NPs are within the nanometer range of size. High negative surface charge values are obtained and indicate the high suspension stability of the prepared formulation. The in vitro release studies showed that GS is released from Alg NPs in a sustained and prolonged manner. The ex vivo permeability of GS through rat skin is enhanced significantly after encapsulation in the negatively charged Alg NPs. We successfully reported a highly stable nanoparticlulate system using Alg NPs that permits the encapsulation of GS for topical administration, overcoming the disadvantages of oral administration.
Linking carbon and nitrogen spiraling in streams

Anthropogenic activities have altered biogeochemical cycles and the fate of organic carbon (OC) and nutrients in freshwater ecosystems. To investigate coupled OC and nutrient cycling and fate in streams, we compared the spiraling lengths (S) and uptake velocities (vf) of OC and nitrate (NO3−) in headwater streams (n = 72) across different land uses (i.e., agricultural, urban, natively vegetated) and regions (n = 8) in the United States. We did these comparisons with data collected for the second Lotic Intersite Nitrogen eXperiment (LINX II; Mulholland et al. 2009). OC spiraling lengths (SOC) in reference (21–4180 m) were shorter than in agricultural streams (89–37,156 m) and urban streams (104–12,605 m). OC mineralization velocities (vf−OC) and NO3− uptake velocities (vf−NO3) were weakly positively correlated across all sites (r = 0.33, p = 0.008). The strongest correlations between OC mineralization and NO3− uptake were in streams with gross primary production (GPP) similar to ecosystem respiration (ER) and human-altered streams (all agricultural streams: r = 0.56, p = 0.008, GPP∶ER = 0.6; all urban streams: r = 0.73, p < 0.001, GPP∶ER = 0.5). Additionally, the distances traveled by OC and NO3− before they were permanently removed from the stream by mineralization (SOC) or denitrification (Sw–den) were similar in magnitude, although SOC was shorter than Sw–den in most streams. This study demonstrates how OC and NO3− spiraling can be used to investigate how region and land use influence coupled OC-NO3− interactions and fate.
Rotor Current Oriented Control Method of DFIG-DC System Without Stator Side Sensors

This letter proposes a novel stator power and frequency control method of doubly-fed induction generator (DFIG)-dc system, which is based on rotor current orientation and avoids using stator side sensors. By means of establishing the relationship of the rotor current vector, stator active power, and stator frequency, the stator active power can be controlled by the angle between the rotor current vector and stator voltage vector. The stator frequency can be controlled by the magnitude of the rotor current vector. The stator active power is calculated by dc voltage and dc current at stator side. In this way, the stator voltage and current sensors can both be eliminated. Furthermore, the stator frequency and orientation angle are acquired by the power control loop, which avoids using voltage model or current model. In this way, both parameter dependency and dc sampling uncertainties can be eliminated. Finally, experiments based on a 1-kW DFIG-dc setup were carried out to verify the proposed method.
Melanoma for Primary Care

The incidence of newly diagnosed malignant melanoma is rapidly increasing. In 2016, it is estimated that there will be 76,380 new cases with 10,130 deaths in the United States. Incidence has increased from 1 in 1500 persons born in the early 1900s to 1 in 50 of Caucasian persons born in 2014, 1 in 200 Hispanics, and 1 in 1000 for African-Americans. Unlike basal and squamous cell carcinoma, malignant melanoma correlates more with intense intermittent UV radiation exposure. Malignant melanoma is the aggressive therapy-resistant skin cancer of melanocytes where thickness of the tumor is the most important prognostic factor. The ABCDs (Asymmetry, Border Irregularity, Color Variation, Diameter >6 mm) of melanoma serve as the foundation for patient education, but the use of EFGs (Evolving, Elevation, Firmness, Growth) provide a more comprehensive screening method for malignant melanomas. The authors recommend self-skin examinations and that family physicians maintain a high clinical suspicion in high risk patients since early diagnosis with appropriate treatment significantly impacts survival.
Prognostic significances of interleukin-17-producing cells and Th17 cells in malignant cancers: a meta-analysis of the literatures

Background and purpose As a proinflammatory factor, interleukin-17 (IL-17) can play a role in both tumor promotion and suppression. IL-17 is traditionally regarded as secreting mainly by CD4+ T helper cells (Th17 cells), while other immune subsets have been proved to produce IL-17, called IL-17+ cells. Considerable studies have drawn controversial conclusions about association between IL-17+/Th17 cells and prognosis of cancer patients. This meta-analysis was performed to systematically and quantitatively analyze prognostic values of IL-17+ cells and Th17 cells in cancer patients. Methods A comprehensive retrieval was conducted in Pubmed (MEDLINE) and EMBASE databases. Pooled risk ratios (RRs) or hazard ratios (HRs) and corresponding 95% confidence intervals (CI) were calculated to evaluate the prognostic values of IL-17+ cells and Th17 cells in cancer patients. Results A total of 42 studies with 5039 patitents were included. High IL-17+ cells was significantly associated with tumor recurrence (RR = 4.23, 95% CI [1.58, 11.35]), worse disease free survival (DFS) (HR = 1.84, 95% CI [1.22, 2.77]) and overall survival (OS) (HR = 1.39, 95% CI [1.04, 1.87]), especially in cancers of digestive system. Besides, no significant difference was observed between high IL-17+ cells and histological grade, lymph node metastasis, tumor volume, clinical stages or distant metastasis. Moreover, there was no significant difference in OS between high and low Th17 cells in cancer patients (HR = 0.93, 95% CI [0.58, 1.49]). Conclusions This meta-analysis suggests high IL-17+ cells could be an indicator for worse survival in patients with malignant cancers, especially with cancers of digestive system. Although high Th17 cells appears to have non-statistically significance on prognosis, more clinical studies should be implemented to investigate the underlying function of Th17 cells within tumor microenvironment. This study put forward a new insight for potential application of anti-IL-17 target therapy in cancer therapeutics.
Determining the Effects of Eugenol on the Bond Strength of Resin-Based Restorative Materials to Dentin: A Meta-Analysis of the Literature

The aim of this study was to determine whether the residual presence of eugenol in coronal dentin may compromise the bond strength of resin-based restorative materials. A search was performed on MEDLINE/Pubmed, Scopus, and by hand search for relevant papers. No restriction was applied for language and publication date. The studies selected for analysis tested specimens with reduced size (micro-shear bond strength (μSBS) and micro-tensile bond strength (μTBS)) of adhesive systems and resin-based restorative materials applied to coronary dentin “contaminated” with eugenol-based materials. The search provided 335 articles, but only 10 studies met the inclusion criteria. The pooled global analysis showed a significant influence of eugenol, as it negatively influenced the bond strength of resin-based restorations (5.79 (3.31–8.28) MPa, p < 0.00001). The subgroup analyses for conventional etch-and-rinse (p = 0.003) and self-etch (p < 0.0004) adhesive systems, as well as for μSBS (p = 0.01) and μTBS (p < 0.0001), showed a negative influence of eugenol on the bond strength. Data were statistically heterogeneous. However, it was possible to observe that eugenol could negatively affect the bonding of resin-based restorative materials to dentin. Further evidence is necessary in order to acquire more accurate information about this issue and confirm that the residual presence of eugenol in dentin compromises the bond strength of resin-based materials.
Distributed Relative Localization Using the Multidimensional Weighted Centroid

A key problem in multiagent systems is the distributed estimation of the localization of agents in a common reference from relative measurements. Estimations can be referred to an anchor node or, as we do here, referred to the weighted centroid of the multiagent system. We propose a Jacobi over-relaxation method for distributed estimation of the weighted centroid of the multiagent system from noisy relative measurements. Contrary to previous approaches, we consider relative multidimensional measurements with general covariance matrices not necessarily diagonal. We prove our weighted centroid method converges faster than anchor-based solutions. We also analyze the method convergence and provide mathematical constraints that ensure avoiding ringing phenomena.
Communication—Electrochemical Impedance Signature of a Non-Planar, Interdigitated, Flow-Through, Porous, Carbon-Based Microelectrode

Top and bottom microelectrode glass slide sandwiches a channel made of adhesive tape and packed with reduced graphene oxide to make a new non-planar interdigitated microﬂuidic device. Novel device integration allows packing of any transducer material at room temperature with no instrument. Electrical impedance spectroscopy signal is stable over long times, ﬁts an equivalent circuit with well-deﬁned circuit elements. Flow visualization concurs that electric double-layer signal shifts to high frequency due to disruption of the diffusive process from increased convective ﬂow. Charge transfer resistance appears at higher frequencies making the device rapid with high signal to noise ratio.

An Online Incentive Mechanism for Crowdsensing With Random Task Arrivals

In this article, an online truthful mechanism is designed for mobile crowdsensing systems. Traditionally, the scenario where participants arrived at the platform in an online manner has been widely discussed in existing works. On the contrary, we focus on random task arrival case to design an online truthful mechanism by jointly considering the cost budget and the requirement of sensed data of each participant. Specifically, when the task arrives, the platform must make decisions in a sequence to select a specific number of participants to obtain a better competitive ratio (CR). To address this issue, an online strategy-proof incentive mechanism is designed to minimize the social cost of the whole system and achieve truthfulness by applying the auction framework. Moreover, in order to further improve the CR of the online algorithm, a more efficient online scheme is proposed if more information on the participants is available at the platform. Theoretical and simulation results demonstrate the effectiveness of our proposed online truthful mechanisms.

Morphological evaluation of ultralow density microcellular foamed composites developed through CO2-induced solid-state batch foaming technique utilizing water as co-blowing agent

In this work, microcellular acrylonitrile-butadiene-styrene foams were developed with utilization of water as a co-blowing agent and CO2 as the primary blowing agent through the solid-state batch foaming process. The effect of saturation parameters with the content of the co-blowing agent has been studied extensively for various foaming attributes. The co-blowing agent enhanced the average cell size and the expansion ratio which are useful for better thermal insulation. The maximum expansion ratio of 29.9 obtained from the effect of saturation temperature and co-blowing agent, 23.6 from the effect of saturation pressure and co-blowing agent, and 22.4 from the effect of saturation time and co-blowing agent. The co-blowing agent significantly affects the cell morphology of polymeric foam with saturation parameters.
A Comparison of Fermentation Kinetics in the Rumen of Grazing Sheep on a Dwarf Bamboo Pasture and a Grass Pasture

Native grasses grown as forest understory are important forage resources for grazing ruminants and in agroforestry. Dwarf bamboo is one such typical grass and has traditionally been used in Japan. The name “dwarf bamboo” refers to a group of native grasses from certain genera (e.g., Sasa spp. and Pleioblastus spp.). These grasses are generally rhizomatous, perennial, and semi-woody (Usui, 1961). The results of an earlier study suggested that the in sacco ruminal degradation of the dwarf bamboo was inferior to that of a common tropical grass (Yayota et al. 2009), and cattle grazing on a forest pasture dominated by a dwarf bamboo could not satisfy their energy requirement in fall regardless of forage availability (Nakano et al. 2007). However, little information is available about the fermentation kinetics of dwarf bamboo or of many other native forage plants in the rumen. Understanding fermentation kinetics will be useful to improve the utilization of this grass and to plan supplemental feeding strategies. The objective of this study was to clarify the fermentation kinetics of a dwarf bamboo (Pleioblastus argenteostriatus f. glaber) in the rumen relative to the fermentation kinetics of a common grass.
Improving the Understanding and Care Management of Mental Health High-Cost Patients

High-cost patients are a small group of health care users who account for a relatively large proportion of resources. Among these patients, our literature review confirmed that limited work has focused on those who use a high amount of mental health and addiction services. We found that the majority of these patients’ costs were due to psychiatric hospitalizations, some of which could be reduced through better care management. Among this mental health high-cost subgroup, our predictive model identified those at risk of any psychiatric hospitalization in Ontario. Identified patients were more likely to be male, younger, and a first-generation immigrant; live in low-income neighbourhoods or rural areas; have a past hospitalization with a main diagnosis of mood disorder; and have a high number of recent psychiatric hospitalizations. For some of these identified patients, our business case analysis supported investments in interventions that could reduce unnecessary hospitalization costs.
Effect of enzyme‐assisted hydrolysis on protein pattern, technofunctional, and sensory properties of lupin protein isolates using enzyme combinations

Abstract The modification of lupin protein isolates (LPI) by means of enzymatic hydrolysis (Lupinus angustifolius cultivar Boregine) was performed with four enzyme preparations (Alcalase 2.4 L, Papain, Corolase 7089, and Neutrase 0.8 L) in a one‐ and two‐step process to determine the efficacy for the destruction of major IgE‐reactive polypeptides and the evaluation of the technofunctional and sensory properties of lupin protein hydrolysates. Combinations of Alcalase 2.4 L and Papain were most effective in the degradation of polypeptides in L. angustifolius as measured by sodium dodecylsulfate–polyacrylamide gel electrophoresis. The enzymatic hydrolysis of the LPI increased their technofunctional properties such as protein solubility, foam activity, and emulsifying capacity almost independently of the enzyme preparation used. The sensory results showed a significant increase in bitterness from 1.9 for LPI to 5.7 for the combination of Alcalase 2.4 L and Papain in one‐step process. The aroma attributes of the hydrolysates were very similar to untreated LPI. The results of this study show the possibility of enzymatic hydrolysis of LPI to destroy the major IgE‐reactive polypeptides that increase the technofunctional properties of the isolates and thus their use in human nutrition as food ingredients.
