Intrusion Detection Using a New Hybrid Feature Selection Model

Intrusion detection is an important topic that aims at protecting computer systems. Besides, feature selection is crucial for increasing the performance of intrusion detection. This paper employs a new hybrid feature selection model for intrusion detection. The implemented model uses Grey Wolf Optimization (GWO) and Particle Swarm Optimization (PSO) algorithms in a new manner. In addition, this study introduces two new models called (PSO-GWO-NB) and (PSO-GWO-ANN) for feature selection and intrusion detection. PSO and GWO show emergent results in feature selection for several purposes and applications. This paper uses PSO and GWO to select features for the intrusion detection system. Furthermore, in this study, a new emergent feature selection method using the interstation of (PSO and GWO) features is developed. Also, this research examines the Most frequently Repeated Features from (PSO and GWO) and gives it the name (MRF). This study runs PSO and GWO for a specific number of iterations, which the user could define. Each feature selection model runs independently, and the selected feature set is saved. PSO features, GWO features, the intersection of (PSO and GWO) features, and MRF features are tested at the next stage. This research uses the UNSW-NB15 dataset for evaluation purposes. Furthermore, experiments are implemented using two classifiers: Naïve Bayesian (NB) and Artificial Neural Networks (ANN). The results show that PSO and GWO are highly acceptable for the selection of intrusion detection features. Besides, the intersection of (PSO and GWO) features gives an emergent result with a minimum number of features. Moreover, MRF features show highly acceptable results. The evaluation process criteria are true positive, false positive, false negative, precision, and recall. The experiments demonstrate that MRF features give a good result related to precision and recall. Finally, experiments show that the performance of (PSO-GWO-NB) classifier is better than (PSO-GWO-ANN) for feature selection and intrusion detections.

Functional Characteristics of Nakdong Technique Treated on Paulownia Wood Surface

Nakdong technique is an unfamiliar scorching treatment using an iron heated in a kiln over 1000℃. It is a typical convention in Asian countries to treat Nakdong on the surface of paulownia species. The scorching treatment changes the surface characteristics as well as the color of the wood. This study focused on the effects of functional features such as water resistance, anti-mold, anti-termite, and sound improvement because this treatment is usually used on paulownia wood-bodied musical instruments surface. It took 28''57" for Nakdong-iron treated surface to absorb a droplet of water. The absorbance time of iron treated surface was longer than that of torch treated one. There was no noticeable effect on the anti-mold test. On the anti-termite test, there was nearly 3% more mean mass loss on the torch samples than controlled and iron treated ones. In examining the sound radiation coefficient before and after Nakdong treatment, the Nakdong-iron treated surface showed an increase in the average value of 1.2 m4/kg s, which means that it has sound quality improvement. Through this research, the Nakdong technique results are expected to be used as basic-data for further research and give a practical idea for using the traditional treatment method on the wood surface.
Future Forests: Forecasting Social and Ecological Consequences of Genetic Engineering

Genetic engineering could result in a dramatic transformation of the forest products industry, increasing corporate economic power and concentrating timber production in those regions most suited to industrial-scale tree plantations. We briefly review arguments in favor of and in opposition to genetic engineering in forestry, and describe the constellation of forces promoting this technology. We then examine possible social consequences with specific reference to the pulp and paper industry in the southeastern United States. This study is exploratory in nature, forecasting possible consequences of a development that has not yet taken place. We suggest that the consequences are potentially far-reaching.
Snow-Pit Record from a Coastal Antarctic Site and Its Preservation of Meteorological Features

Polar snow pits or ice cores preserve valuable information derived from the atmosphere on past climate and environment changes. A 1.57-m snow-pit record from the coastal site (Styx Glacier) in eastern Antarctica covering the period from January 2011 to January 2015 was discussed and compared with meteorological variables. The dominant contribution of the deposition of sea-salt aerosols due to the proximity of the site to the ocean and processes of sea ice formation was revealed in the ionic concentrations. Consistent seasonal peaks in δ 18 O, δ D, MSA, , and indicate the strong enhancement of their source during warm periods, whereas the sea-salt ions (Na + , K + , Mg 2+ , Ca 2+ , Cl − , and ) exhibit a distinct distribution. Monthly mean δ 18 O positively correlates with the air temperature record from an automatic weather station (AWS) located in the main wind direction. Despite the shortness of the record, we suspect that the slight depletion of the isotopic composition and lowering of the snow accumulation could be related to the cooler air temperature with the decrease of open sea area. Consistency with previous studies and the positive correlation of sea-salt ions in the snow pit indicate the relatively good preservation of snow layers with noticeable climate and environmental signals [e.g., changes in sea ice extent (SIE) or sea surface temperature]. We report a new snow-pit record, which would be comparative and supportive to understand similar signals preserved in deeper ice cores in this location.

Universal Fluorescence Enhancement Substrate Based on Multiple Heterostructure Photonic Crystal with Super‐Wide Stopband and Highly Sensitive Cr(VI) Detecting Performance

Universal fluorescence (FL) enhancement is achieved based on a multiple heterostructure photonic crystal (MHPC) with a super‐wide stopband. This MHPC film is fabricated by layer‐by‐layer deposition of annealed colloidal crystal monolayers with gradient sizes, and it displays a broadened stopband (from 280 to 650 nm) that can overlap with the excitation wavelength (E) and the emission wavelength (F) of most commonly used fluorescent media. More than 100‐fold FL enhancement of [Ru(dpp)3Cl2], rhodamine 6G (Rh6G), and rhodamine B (RhB) on the MHPC is observed compared to that on a glass substrate. This super‐wide stopband MHPC may find significant applications for augmenting FL intensity in chemical and biochemical sensing, imaging, disease diagnosis, and environmental monitoring. The function of MHPC/rhodium B hydrazide composites is further demonstrated in the semiquantitative detection of Cr(VI), and the limit of detection of Cr(VI) is effectively improved to 0.2 ppb.
Parameter estimation for ocean biogeochemical component in a global model using Ensemble Kalman Filter: a twin experiment

<p>Ocean biogeochemical (BGC) models utilize a large number of poorly-constrained global parameters to mimic unresolved processes and reproduce the observed complex spatio-temporal patterns. Large model errors stem primarily from inaccuracies in these parameters whose optimal values can vary both in space and time. This study aims to demonstrate the ability of ensemble data assimilation (DA) methods to provide high-quality and improved BGC parameters within an Earth system model in idealized twin experiment framework. &#160;We use the Norwegian Climate Prediction Model (NorCPM), which combines the Norwegian Earth System Model with the Dual-One-Step ahead smoothing-based Ensemble Kalman Filter (DOSA-EnKF). The work follows on Gharamti et al. (2017) that successfully demonstrates the approach for one-dimensional idealized ocean BGC models. We aim to estimate five spatially varying BGC parameters by assimilating Salinity and Temperature hydrographic profiles and surface BGC (Phytoplankton, Nitrate, Phosphorous, Silicate, and Oxygen) observations in a strongly coupled DA framework &#8211; i.e., jointly updating ocean and BGC state-parameters during the assimilation. The method converges quickly (less than a year), largely reducing the errors in the BGC parameters and eventually it is shown to perform nearly as well as that of the system with true parameter values. Optimal parameter values can also be recovered by assimilating climatological BGC observations and challenging sparse observational networks. The findings of this study demonstrate the applicability of the approach for tuning the system in a real framework. </p><p>&#160;</p><p><strong>References</strong>:</p><p>Gharamti, M.

The Effect of Succession on Family Business Innovation and Leadership: Case Analysis of Australia Smes

This study investigates the effect of succession on family-owned businesses ' innovation and leadership. Multiple factors affect the socio-economic development of any nation, such as unemployment rates, literacy rates, and so on. Likewise, and family-owned businesses are among one of those factors. The whole study will be conducted in an Australian context because 70% of total businesses are family-owned businesses; therefore, can provide an in-depth dynamics of family firms. A family business is based on the succession, i.e., transfer of business ownership and control from one family member to another, mostly from one generation to another. The model regarding transfer of knowledge and successor's development in a family firm has been used. This model is based on the resource-based theory. As per this theory, knowledge is an essential resource for a firm, and it has two major categories, i.e., explicit knowledge and tacit knowledge. The tacit knowledge is more difficult to be transferred than explicit knowledge. It is assumed that family businesses have lesser problems than corporate. In current times, innovation for business success is the topmost priority, which has yet to be explored for family-owned businesses in Australia. Therefore, it is essential to explore the impact and consequences of business innovation on family-owned that small and medium businesses. This study aims to explore the succession of family-owned businesses and the effect on business innovation and leadership. This study plays a significant role in conventional family businesses that come across succession issues and have limited but efficient resource allocation within family businesses. The first objective of this study is to determine post intergenerational succession innovation. Secondly, the impact of succession on innovation. It also discovers the factors that impact innovation. A qualitative research approach will be followed by conducting interviews with open-ended questions to 24 respondents that include both predecessors and successors. The right to autonomy, secrecy, and privacy of all respondents will be protected under ethical consideration.
Effect of zinc nutrition on yield of rice-wheat cropping system and soil properties

A study was conducted in an ongoing experiment under AICRP on micronutrients at nursery jhilli of RPCAU, research farm. The experiment consisted of thirteen treatments, of which twelve combinations were of four doses of zinc (Zn) (2.5, 5.0, 7.5 and 10 kg ha-1), three frequencies (only once, alternate year and every year) of application along with control with the no-zinc application. Rice and wheat crops were grown in succession with the recommended dosages of fertiliser viz. 120:60:40 of N: P2O5: K2O applied as Urea, DAP, and Potash, respectively. Surface soil samples (0-15 cm) were collected after the harvest of the wheat crop in the year 2018, i.e. after completion of six years of the experiment, and analysed for soil physical and chemical properties. The availability of nitrogen, sulphur, organic carbon content and aggregate stability increased, and the bulk density, phosphorous availability decreased with increasing doses and zinc application rates. No effect on soil availability of potassium, pH and EC. The treatment T7 i.e., application of zinc @ 7.5 kg Zn ha-1 in alternate year application was the best treatment with regards to yield of rice-wheat cropping (982.9 q ha-1) and also for good physical and chemical properties of the soil.
Adsorption of Ammonia on Zirconium-Based Metal-Organic Framework: A Combined Experimental and Theoretical Study

Zirconium-based Metal-organic framework ((Zr6O4(OH)4(1,4-benzenedicarboxylate)6), UiO-66) is one of the most outstanding MOFs for heterogeneous catalysis owning to its high thermal and chemical stabilities. 1,4-benzenedicarboxylate, which is an organic linker of UiO-66, can be functionalized by a sulfonic acid group (UiO-66-SO3H) for several acid-catalyzed reactions. In this work, the structures and acidity of the synthesized UiO-66 and UiO-66-SO3H were characterized using X-ray diffraction, IR-spectroscopy and adsorption experiments. The adsorption of ammonia on UiO-66 type frameworks was studied on the C162H122O67SZr12 cluster model by different DFT functionals including B3LYP, CAM-B3LYP, M06-L, PBE, TPSS and ωB97X-D. The adsorption energies were calculated to be -16.4, -19.2, -18.0, -19.7, -17.4 and -19.3 kcal/mol, respectively, which agreed well with the value from MP2 calculation (-17.9 kcal/mol). This study provides a guideline on the suitable calculation models and yield more insights on the adsorption in acid-functionalized UiO-66 MOF framework.
Regional Impact of Ozone Precursor Emissions on NOX and O3 Levels at ZOTTO Tall Tower in Central Siberia

Seasonal variations of the near‐surface NOX (= NO + NO2) and ozone (O3) mixing ratios at Zotino Tall Tower (ZOTTO), a remote site in central Siberia, are described for years 2007–2014. Conditional probability function analysis and back trajectories are used to determine the origins of clean (continental baseline, CB) and regional emissions‐influenced air. High NOX levels at the site are observed for air from industrial regions of western Siberia and Ural Mountains, whereas CB air originates from remote areas of North Eurasia within 55°–70°N. The estimated annual means of daytime O3 and NOX mixing ratios for CB air are 27.0 and 0.44 ppbv, correspondingly, versus the similar quantities of 27.9 and 0.79 ppbv for all data. Monthly ozone for CB air shows a distinct maximum in April, as is the case for Northern Hemisphere midlatitude baseline (NHMLB) air at the European inflow boundary according to the surface ozone data for Mace Head and Norwegian monitoring sites, and a minimum in late summer–early autumn reflecting a weak continental‐scale ozone production from biogenic sources of ozone precursors and wildfire emissions throughout the warm season. During spring and early summer under hot weather conditions, regional anthropogenic and wildfire emissions are an important source for ozone in the continental boundary layer over southern and central Siberia, resulting in surface ozone levels compared to or larger than those observed in NHMLB air. Throughout the remaining part of year, the central North Eurasia represents a sink for tropospheric ozone on a hemispheric scale.
Suppression of vacancies boosts thermoelectric performance in type-I clathrates

Intermetallic type-I clathrates continue to attract attention as promising thermoelectric materials. Here we present structural and thermoelectric properties of single crystalline Ba8(Cu,Ga,Ge,v)46, where v denotes a vacancy. By single crystal X-ray diffraction on crystals without Ga we find clear evidence for the presence of vacancies at the 6c site in the structure. With increasing Ga content, vacancies are successively filled. This increases the charge carrier mobility strongly, even within a small range of Ga substitution, leading to reduced electrical resistivity and enhanced thermoelectric performance. The largest figure of merit ZT =0.9 at 900 K is found for a single crystal of approximate composition Ba8Cu4.6Ga1. 0Ge40.4. This value, that may further increase at higher temperatures, is one of the largest to date found in transition metal element-based clathrates.
Hydrophilic cell-derived extracellular matrix as a niche to promote adhesion and differentiation of neural progenitor cells

The natural extracellular matrix (ECM) offers a dynamic and intricate microenvironment, which serves as a structural support and regulates cell phenotype and its function. Recently, ECM has been revealed as a favorable and biocompatible architecture for stem cell adhesion and growth in cellular therapy to treat various diseases. However, cell-derived ECM is rarely used as a culture substrate for anchorage-dependent cells, such as neural progenitor cells (NPCs), which have the potential to differentiate into basal forebrain cholinergic neurons (BFCNs) for Alzheimer's disease. Here, we report mouse embryonic fibroblast (MEF)-derived ECM, with an appropriately hydrophilic property (water contact angle of 66.8°) to mimic the neural niche for NPCs. In addition, MEF-derived ECM possesses a nanotopological surface, plentiful kinds of components and exhibits excellent adhesion properties for anchoring NPCs. Compared with a laminin-coated plate, MEF-derived ECM promotes NPC proliferation and differentiation into BFCNs by ∼1.6 fold and ∼3.1 fold, respectively, consequently enhancing the production of acetylcholine by ∼2.0 fold. This MEF-derived ECM could be a favorable cell culture carrier for NPC attachment, with great potential for applications in stem cell therapy for Alzheimer's disease.
Machine Learning calibration of Angle of Arrival methods based on different experimental Unified Linear and Rectified Array measurements

Generic Angle of Arrival methods for indoor positioning are highly affected by specific antenna and environment scenarios through design impurities or multipathcomponent propagations. Here we acquired a large dataset of four different antenna designs in three different measurement environments with >140000 snapshots obtained from Bluetooth 5.1 receiver. Using the spatial power spectral densities of the PDDA angle of arrival algorithm as feature set for a small Random Forest model, we could show that angle estimation performances for all antennas in all measured environments were significantly improved (PDDA MAE >16 vs RF MAE < 3). Based on the small model size the proposed architecture can be implemented in microcontroller applications for super resolution angle of arrival applications.
