HIDE ’N SEEK REVISITED – FULL

Rootkits are designed to hide information. They are no longer utilized only by highly skilled individuals targeting UNIX machines. Advanced Windows rootkits have emerged and are gaining popularity among intruders. The alarming news is that malware writers are adopting rootkit techniques, which allows them to create a new breed of worms, Trojans and spyware that are able to avoid detection by hiding their presence on the system. Traditional anti-virus and intrusion detection systems are powerless against this emerging threat, since they rely on the validity of the information provided by the operating system. This information cannot be trusted if the kernel or the application programming interfaces are modified by malware. This paper is a continuation of the academic research done by one of the authors [1]. It provides an introduction to the hiding techniques utilized by advanced Windows rootkits. This information is essential for understanding the threat and for fighting it. In addition, new techniques for detecting hidden objects are presented. They form the foundation for the next generation of detection tools. Finally, the paper presents and analyses a new application that brings rootkit detection onto the desktop of home users.
A Nonlinear Dynamic System In Behavioral Finance : Evidence From Chinese Stock Market

This paper uses linear and nonlinear Granger causality tests to examine a dynamic behavioral finance system which composed by the stock index price, investor sentiment and the willingness to investment. We find that the linear dynamic system is simple and unidirectional, but nonlinear dynamic system is complex and bidirectional. And we can predict the index return more accurately by using the nonlinear dynamic system, because the linear dynamic system may lose some variables which have nonlinear effects on the index return. Keywords-Investor sentiment; Willingness to investment; Non-linear Granger causality; Behavioral finance
Metabolism Energy, Nitrogen Retention, and Mineral Retention of Phosphorus Calcium and Zinc of Sugarcane Juice in Broilers

Poultry feed derived from grains has an anti-nutrient phytic acid. Naturally, phytate forms a complex bond with some minerals (P, Zn, Fe, Mg, and Ca), protein, and amino acids. The mineral-phytate complex cannot be absorbed by the small intestine of non-ruminant livestock and will adversely affect the availability of minerals in the ration. One way to improve the efficiency of mineral and protein utilization from phytate is using phytase. Sugarcane juice containing nutrients and phytase is very potential as liquid supplement for broiler chickens as it can hydrolyze phytic acid. The purpose of this study was to determine the retention of nitrogen, metabolism energy, and retention of minerals (P, Ca and Zn) of sugarcane juice in broilers. The study was conducted for 7 days using metabolism cages for 28 broilers of 5 weeks old with 6 treatments of 4 replications, 4 for endogenous. The results showed that the administration of 2.5%/kg sugarcane juice in the ration as well as in 2.5%/liter sugarcane juice in drinking water could provide the same result as giving commercial phytase 250-500 FTU/kg on the retention of nitrogen, metabolizeable energy, and retention of minerals P, Ca and Zn.
Endotracheal Intubation by Paramedics Using Neodymium Magnet and Modified Stylet in Simulated Difficult Airway: A Prospective, Randomized, Crossover Manikin Study

Background The present study evaluates the success and efficacy of endotracheal intubation (ETI) using a modified intubation stylet and a magnet system to direct the stylet into the trachea. The system was developed by the researchers in an attempt to increase the success and efficacy of ETI. Methods ETI procedures were performed on an airway management manikin by emergency medical technicians with at least four years of experience in ETI. The technicians used a stylet modified with an iron ball affixed to the tip and a neodymium magnet, designed specifically for the study. The intention was to guide the endotracheal tube into the trachea at the level of the thyroid and cricoid cartilages on the manikin with the aid of the modified stylet and the magnetic force of the neodymium magnet. The success rate, completion time, and degree of difficulty of two procedures were compared: magnetic endotracheal intubation (METI) and classic ETI (CETI). Results The success rate was 100% in both groups. The mean completion times for the METI and CETI procedures were 18.31 ± 2.46 s and 20.01 ± 1.95 s, respectively. There were significant differences in completion time and degree of difficulty between the METI and CETI procedures (both p=0.001). Conclusions We found the use of a neodymium magnet and modified stylet to be an effective method to guide the endotracheal tube into the trachea. The present study may provide a basis for future studies.
Optimization and Wireless Networks with Jamming Characteristics

In Wireless 802.11 networks, Multiple-path source r outing allows data source node to distribute the to tal traffic among the possible available paths. However, in this case jam ming effects were not considered. Recent work has p resented jamming mitigation scheme, anti-jamming Reinforcement System on 802.11 networks by assessing physical-layer fu nctions such as rate adaptation and power control. Rate adaptation algor ithms significantly degrade network performance. Appropriate tuning of carrier sensing threshold allows transmitter to sen d packets even on jam that enable receiver to captu re desired signal. Efficient schedules need to be investigated for redundant tra nsmission to perform well in presence of jammer. In this paper, the proposal in our work presents an Efficient Time and Transmis sion Schedule Scheme for wireless 802.11 networks i n presence of jamming that guarantee low waiting time and low staleness of data. Schedules are optimal even jamming signal has energy limitations. Each packet is encoded by an error-cor recting code (Reed-Solomon). Reed solomon code allow schedule to minimize waiting time of the clients and staleness of the received data. Jammers have restrictions on length of jamming pulses and length of intervals between subsequent jamming pulses.
Attachment of a Pseudomonas-like bacterium and Bacillus coagulans to solid surfaces and adsorption of their S-layer proteins

SUMMARY: The role of S-layer proteins in bacterial adhesion to solid surfaces was investigated by determining whether there was a relationship between the adsorption of S-layer protein and the attachment of the source bacteria to a series of substrata exhibiting a range of water-wettabilities. Polystyrene substrata, prepared by treatment with H2SO4, provided advancing water contact angles ranging from 76° to 46°. The test bacteria were a Pseudomonas-like strain, designated EU2, and the thermophilic bacterium Bacillus coagulans. In two out of four cases, S-layer adsorption paralleled cell attachment. Numbers of attached EU2 and amount of S-layer adsorption in phosphate buffer both increased with increasing substratum hydrophobicity. Numbers of attached B. coagulans and S-layer adsorption in distilled deionized water both decreased with increasing substratum hydrophobicity. The inconsistencies in attachment and S-layer adsorption observed in the remaining experiments were possibly due to the fact that S-layer proteins were free to adsorb by both inner and outer faces, whereas S-layer on the cell could adsorb only by the outer face. The results indicated that S-layers may play a role in bacterial adhesion to surfaces, but that the adhesiveness of S-layers depends upon their specific chemistry and environmental conditions such as medium composition and temperature.
PREY ALENCE OF DENGUE VmAL INFECTIONS AMONG FE aRILE PA l'UENTS IN l\10MBASA COUNTY

Dengue virus infection is one of the major global public health problems, It is caused by one of the four dengue virus (DENY) serotypes that are transmitted by Aedes mosquitoes. Following infection, an individual remains vulnerable to re-infection with a different serotype of the DENY. The infection usually occurs with clinical manifestations ranging from an asymptomatic or mild febrile illness as classical dengue fever to the potentially life-threatening illness, dengue hemorrhagic fever and dengue shock syndrome. Despite the public health relevance, prevalence of DENV infections among febrile patients in Mombasa County is unknown. This study was conducted from February 2012 to July 2012 among patients visiting Coast Province General Hospital with high fever. The study was aimed at determining the prevalence of DENV infection among febrile patients and describe the month-wise trend of the disease. A total of 390 blood serum samples were collected and DENV specific IgM and flavivirus IgG antibodies were determined by in-house enzyme linked immunosorbent assay (ELISA). Out of 390 febrile cases, 54 (13.9%) were found to be positive for anti-DENY IgM. Among the 54 dengue positive cases, 37 (68.5 %) were primary DENY infection and 17 (31. 5%) were secondary DENY infection. The most 'affected age group was 36-45 years (20.4%) and least affected group being 6-·15years (8.3%). Prevalence in difference age groups was statistically significant (p = 0.021). Primary DENV infection was common among the age group between 36-45 years while secondary dengue affected mostly the age group 26-35 years. In terms of primary DENV infection against secondary DENV infection, it was observed that infants «1 year) were the most affected but this was not statistically significant (p = 0.057). The relationship between gender and DENV infections was not statistically significant (p = 0.936). Although, females aged between 26-35 years (p = 0.010) and males aged above 46 years (p = 0.012) were the most affected with DENY infection. Month-wise distribution of DENV infection was' observed in February (20.0%) with least occurrence in July (4.7%). The association between the month and occurrence of disease was not statistically significant (p = 0.325). The present study has reported 13.9% prevalence of Dengue virus infections as the cause of acute undifferentiated fever among febrile patients in Mombasa County. Thus, calls for government attention to develop resources at hospital laboratories for early dengue diagnosis and management of patients, coupled with general awareness among the public and constant vigilance by the health care officials could help in combating dengue.

Environment-Friendly and Efficient Gaseous Insulator as a Potential Alternative to SF6

Sulfur hexafluoride (SF6) is commonly used in electrical insulation networks due to its superior dielectric properties. However, it possesses a high Global Warming Potential (GWP) of 22,800 times compared to CO2 (at equal mass over a time span of 100 years) and a high atmospheric lifetime. This alarming metric prompted investigation for substitute gases with minor environmental influences. The overall objective of this research is to evaluate refrigerant R152a as a potential alternative for SF6 in electrical insulation systems. R152a gas has a significantly reduced value of GWP (140) and is a cheap insulation medium as compared to SF6. In this paper, dielectric breakdown testing of R152a and a mixture of CO2 with different concentrations have been tested. The dielectric strength of R152a/CO2 gas shows a saturated growth trend with increasing the gap difference, gas pressure and mixing ratio of R152a. Based on our experimental conditions, R152a/CO2 gas reveals good dielectric properties, and insulation performance can reach up to 96% of SF6. Finally, this work will bring a cost-effective and environment-friendly gaseous insulator for utility companies and power equipment manufacturers.
Effect Of Double Thermal Modulation On Heat Transfer In A Square Cavity Heated From Bellow

Article history: Received September 20, 2013 Received in Revised form October, 14, 2013 Accepted 12 January 2014 Available online 14 January 2014 This paper deals with the investigation of thermo-vibrational convection induced by harmonic vibrations of the temperature boundary conditions in a square cavity heated from bellow and containing a low Prandtl number fluid. The governing equations are solved by using a finite volumes method. Effects of thermal modulation on the all regimes occurring in the cavity when convection intensity increases are analyzed. A characteristic modulation frequency allowing the reduction of the average intensity of the flow and heat transfer at the cold wall has been identified. The effect of phase difference between hot and cold temperature is also studied. © 2014 Growing Science Ltd. All rights reserved.
Assessing Investor Belief: An Analysis of Trading for Sustainable Growth of Stock Markets

Investors’ beliefs are the driving force behind the trading of stocks and, hence, sustainable stock returns. Although investors’ beliefs are usually unobservable, this study develops a new approach to estimate investors beliefs. Following well-established rational learning and market microstructure models, it is assumed that informed traders submit market orders according to their beliefs, whereas market makers/uninformed traders make Bayesian inferences about the informed traders’ private signals after observing the total order flows. By fitting intraday transaction data to this model, we can estimate the daily belief uncertainties of informed and uninformed investors; this estimation is performed on S&P 500 stocks. The belief parameters estimated by this approach have incremental explanatory power to bid-ask spreads. The findings show that market makers’ belief uncertainty plays a more important role in determining sustainable stock returns than informed traders’. Implications of these findings include: (a) the larger market maker group is influencing the market trends; (b) this dominant group is making decisions based on diverse types of data; and (c) increased understanding of the diversity of belief parameters may facilitate strategies to enhance sustainable returns, however, stock trading is still significantly influenced by emotive factors worthy of further research.
Isolation of Hydrocarbonoclastic Bacteria and Plasmid Analysis for alk B Gene Primers

Hydrocarbonoclastic microorganisms elaborate a number of hydrocarbons utilising genes that enable them to use crude oil hydrocarbons as carbon sources. These genes could either be located on the plasmid or chromosome. The primary aim of this study was, therefore, to isolate hydrocarbon utilising microbes and profile their plasmid for alkB gene. The physicochemical, microbiological and plasmid analyses were done using standard methods described previously. Plasmid profiling for the alkB gene was carried with four selected bacteria isolates using the universal degenerate primers Rh alkB1-F: ATCTGGGCGCGTTGGGATTTGAGCG, Rh alkB1-R: CGCATGGTGATCGCTGTGCCGCTGC and Pp alkBP-F: TGGCCGGCT ACTCCGATGATCGGAATCTGG, Pp alkBP-R: GCGTGGTGATCCGAGTGCCGCTGAAGGTG. Physicochemical analysis revealed anthropogenic influence on the environment as iron and copper levels were higher than permissible international levels. Aerobic counts for bacteria were higher Original Research Article Edet et al.; SAJRM, 1(3): 1-9, 2018; Article no.SAJRM. 41896 2 than those of fungi with values that ranged from 70 to 92 (x10) CFU/g for bacteria and 14 to 19 (x10 3 ) CFU/g for fungi. Microbiological and biochemical characterisation revealed that the hydrocarbonoclastic bacterial isolates were Enterobacter sp, Bacillus sp, Micrococcus sp, Pseudomonas sp, Corynebacterium sp and Klebsiella sp while the fungal isolates were Penicillium sp, Aspergillus flavus, Fusarium sp, Rhizopus sp and Aspergillus sp. Molecular characterisation revealed that the selected isolates for plasmid profiling were Bacillus thuringiensis, Pseudomonas stutzeri, Bacillus cereus and Klebsiella pneumoniae. Plasmid profiling revealed that none of the isolates were positive for the monoxygenase (alk B) genes. The findings in this study support earlier findings that indicated that the chromosome could indeed a preferred location for domiciliation of functional genes.
Asymptotics of free fermions in a quadratic well at finite temperature and the Moshe–Neuberger–Shapiro random matrix model

We derive the local statistics of the canonical ensemble of free fermions in a quadratic potential well at finite temperature, as the particle number approaches infinity. This free fermion model is equivalent to a random matrix model proposed by Moshe, Neuberger and Shapiro. Limiting behaviors obtained before for the grand canonical ensemble are observed in the canonical ensemble: We have at the edge the phase transition from the Tracy--Widom distribution to the Gumbel distribution via the Kardar-Parisi-Zhang (KPZ) crossover distribution, and in the bulk the phase transition from the sine point process to the Poisson point process. A similarity between this model and a class of models in the KPZ universality class is explained. We also derive the multi-time correlation functions and the multi-time gap probability formulas for the free fermions along the imaginary time.
Clinical Application of the K-Style Acupuncture Score (KSAS): Towards the Establishment of a Novel Rating Scale for Depression in Acupuncture Medicine

In Asian countries, depressed patients has been reported to present physical symptoms more mainly than psychiatric symptoms. However, there is no valid and suitable rating scale for those kinds of depression, especially in accordance with Eastern medicine. With this background, we have developed an original rating scale, the K–Style Acupuncture Score (KSAS), to assess the depression such as masked depression. To verify the KSAS measure, we examined the correlations with other depression scales. We also assessed whether the KSAS could be an indicator to detect the therapeutic effect of acupuncture on depression. Twelve healthy subjects and 30 depressed patients participated in this study and underwent the assessments of psychological batteries and the KSAS measure before and after Press Needle (PN) acupuncture intervention in a randomized, placebo-controlled design. To evaluate a cross-sectional difference between the healthy subjects and depressed patients and longitudinal changes before and after the PN acupuncture in the KSAS, we performed a three-way analysis of variance (ANOVA) with time as a within-subject factor and intervention (active vs. sham) and group (healthy subjects vs. depressed patients) as between-subject factors. We also performed correlation analysis between the KSAS measures and each of the psychological tests. The ANOVA for the total score of the KSAS showed significant main effect of group (F1, 38=9.893, P=0.003) and time-intervention interaction (F1, 38=4.403, P=0.043). Further, we observed significant cross-sectional and longitudinal correlations between the KSAS measure and other psychological metrics. The present study demonstrated the validity and utility of the KSAS measure to assess depression in the context of acupuncture medicine.
High Entropy Alloys for Aerospace Applications

In the aerospace industry, materials used as modern engine components must be able to withstand extreme operating temperatures, creep, fatigue crack growth and translational movements of parts at high speed. Therefore, the parts produced must be lightweight and have good elevated-temperature strength, fatigue, resistant to chemical degradation, wear and oxidation resistance. High entropy alloys (HEAs) characterize the cutting edge of high-performance materials. These alloys are materials with complex compositions of multiple elements and striking characteristics in contrast to conventional alloys; their high configuration entropy mixing is more stable at elevated temperatures. This attribute allows suitable alloying elements to increase the properties of the materials based on four core effects , which gives tremendous possibilities as potential structural materials in jet engine applications. Researchers fabricate most of these materials using formative manufacturing technologies; arc melting. However, the challenges of heating the elements together have the tendency to form hypoeutectic that separates itself from the rest of the elements and defects reported are introduced during the casting process. Nevertheless, Laser Engineering Net Shaping (LENS™) and Selective Laser Melting (SLM); a powder-based laser additive manufacturing process offers versatility, accuracy in geometry and fabrication of three-dimensional dense structures layer by layer avoiding production errors.

The purpose of this study was to review the best available evidence of noninvasive brain stimulation, including repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) for dysphagia after acquired brain injury. We searched randomized controlled trials that compared noninvasive brain stimulation with control used to improve dysphagia after acquired brain injury. We assessed dysphagia severity rating scales and penetration-aspiration scale as outcomes immediately after intervention. We calculated the pooled estimate of the standardized mean difference (SMD) to combine individual results. We included 8 published studies. Two heterogenous trials of 48 patients showed that rTMS was associated with a significant improvement in the dysphagia severity rating scale score (SMD 2.95). Three homogeneous trials of 88 patients showed a significant effect of rTMS on the penetration-aspiration scale score (SMD 0.77). Two homogeneous trials of 34 patients showed that tDCS was associated with a significant improvement in the dysphagia severity rating scale score (SMD 1.20). The review provided low-quality evidence for the effectiveness of noninvasive brain stimulation in improving dysphagia after acquired brain injury. Further trials of larger sample sizes are needed to determine themost appropriate noninvasive brain stimulation protocol. J. Med. Invest. 63 : 153-158,
