Constructing Plan Trees for Simulated Penetration Testing

Penetration Testing (pentesting), where network administrators automatically attack their own network to identify and fix their vulnerabilities, has recently received attention from the AI community. Smart algorithms that can identify robust and efficient attack plans can imitate human hackers better than simple protocols. Current classical planning methods for pentesting model poorly the real world, where the attacker has only partial information concerning the network. On the other hand POMDP-based approaches provide a strong model, but fail to scale up to reasonable model sizes. In this paper we offer a more realistic model of the problem, allowing for partial observability and non-deterministic action effects, by modeling pentesting as a partially observable contingent problem. We suggest several optimization criteria, including worst case, best case, and fault tolerance. We experiment with benchmark networks, showing contingent planning to scale up to large networks.

THE POSTGRES NEXT GENERATION DBMS

The purpose of the POSTGRES project was to build a next generation DBMS to rectify the known deficiencies in current relational DBMSs. This system, constructed over a four year period by one full time programmer and 3-4 part time students is operational and consists of about 180,000 lines of C. POSTGRES is available free of charge and is being used by perhaps 125 sites around the world. This paper describes the major concepts of the system and details its current state. We restrict our attention to the DBMS ‘‘backend’’ functions, and make only passing mention of the front end tools available for POSTGRES.
Anti-inflammatory Effects of Distylium racemosum Extract in a Mouse Model of Allergic Asthma

Abstract Allergic asthma is a complex disorder characterized by chronic airway inflammation. Patients with asthma often show poor adherence to corticosteroid therapy owing to prominent side effects, which provides a rationale to explore new drug classes with a better safety profile. In this study, we sought to discover natural products that inhibit the activity of phosphodiesterase 4, which is considered a potential molecular target for anti-inflammatory therapy. The screening of a plant extract library led to the identification of Distylium racemosum, which inhibited phosphodiesterase 4 activity in vitro and suppressed lipopolysaccharide-induced inflammatory signaling in cultured cells. In a mouse model of ovalbumin-induced allergic asthma, D. racemosum treatment significantly reduced inflammatory responses in the lung, as well as serum immunoglobulin E levels. Although the active constituents of D. racemosum extract and the exact mechanism underlying the in vivo action of D. racemosum remain to be elucidated, our results provide a basis for further investigation of D. racemosum extract as a novel anti-inflammatory agent for allergic asthma.
A Collective Survey on Methodology of Frequent Item Pattern Mining on Web Information

: In today’s world of digital era finding semantic relationship between the information is really a big challenge for data analyzers. So most of the time this process needs the external help of the dictionaries to provide the semantic meanings but many times correlations between the words also plays more important role to get the best semantic. So many ideas are been proposed to get the semantic patterns in between the words of the document. But the proposed method put forwards as idea of getting the frequent item patterns from web pages using crawler which is been powered with the best frequent item algorithm like Éclat. This paper deals with a cumulative survey on the method of frequent item mining on web page information
Organizational culture profile of service and manufacturing businesses in México

The organizational cultures of service and manufacturing firms in the central area of Mexico were assessed using the Cameron & Quinn (1999) Organizational Culture Assessment Instrument (OCAI) for sample of 307 workers. To identify differences, a comparison was made between the four organizational cultures: clan, adhocracy, market and hierarchical. Results show significant differences related to the business, its size, and the gender and the hierarchical position of the worker.
ANTIOXIDANT, ANTI-INFLAMMATORY, AND ANTIDIABETIC ACTIVITY OF HYDROALCOHOLIC EXTRACT OF OCIMUM SANCTUM: AN IN-VITRO AND IN-SILICO STUDY

Objective: Ocimum sanctum is known to be beneficial in the management of diabetes, however, its mechanism remains unexplored. This study wasaimed to gain insite into the mechanisms through which it may counter diabetes and its complications.Methods: Hydroalcoholic whole plant extract of O. sanctum was screened for its antidiabetic potential and ability to counter oxidative andinflammatory stress through various in-vitro assays. Further, bioactive compounds that may be responsible for its antidiabetic activity were predictedthrough molecular-docking studies.Results: Crude extractive yield of 35.43% was obtained from Soxhlet extraction which mainly showed the presence of flavonoids, alkaloids, glycosides, and saponins. Plant extract showed good potential to scavenge 2,2-diphenyl-1-picrylhydrazyl free radical (40.95-68.71%) which may be attributed\ to its high phenolic (0.366 mg gallic acid equivalent/g) and flavonoid (0.113 mg quercetin equivalent/g) contents. Plant showed exceptional antiinflammatory activity which was evaluated through inhibition of protein denaturation (47.61-82.37%) and red blood cell membrane stabilization assay (43.66-78.28%). Further, extract treatment greatly inhibited I±-glucosidase enzyme (34.17-71.45%) but failed to produce noticeable inhibition of I±-amylase activity (1.94-14.88%). Docking studies predicted that rosmarinic acid, stigmasterol, linalool, bieugenol, and aesculin may be responsible for antidiabetic activity possessed by the plant through their interaction with the insulin receptor.Conclusion: These findings conclude that O. sanctum may be beneficial in managing diabetes and its associated complications through inhibitingI±-glucosidase activity, reducing oxidative and inflammatory stress.Keywords: Diabetes mellitus, Ocimum sanctum, Antioxidant, Anti-inflammatory, Docking, Diabetic complications.
A Method for the Synthesis of Tetranitroglycoluril from Imidazo-[4,5-d]-imidazoles with Loss of Dinitrogen Oxide

Abstract : A new method for the preparation of tetranitroglycoluril (TNGU, Sorguyl) is described, in which imidazo-[4,5-d]-imidazoles are nitrated with the elimination of N2O to generate TNGU. This method of TNGU synthesis results in material that is less sensitive than material produced with alternative routes. Additionally, a new spherical morphology of TNGU is disclosed. This morphology exhibits an even higher resistance to external insult even than material synthesized with the new method.

Standard errors and confidence intervals in nonlinear regression: comparison of Monte Carlo and parametric statistics

A Monte Carlo method is employed to characterize distributions of parameter values calculated in nonlinear regression problems. Accurate estimates of confidence intervals are easily obtained. Two illustrative numerical examples are provided to compare the Monte Carlo uncertainty estimates with those derived by use of standard methods of parametric statistics. The customary assumptions that (1) the effects of covariances between pairs of the parameters can bc ignored and (2) that the distributions of the parameters are normal are shown to lead to significant errors, up to 2and 3-fold in the calculated uncertainties. The Monte Carlo method is free from these assumptions and their associated errors.
Universality of ac conduction in disordered solids

The striking similarity of ac conduction in quite different disordered solids is discussed in terms of experimental results, modeling, and computer simulations. After giving an overview of experiment, a macroscopic and a microscopic model are reviewed. For both models the normalized ac conductivity as a function of a suitably scaled frequency becomes independent of details of the disorder in the extreme disorder limit, i.e., when the local randomly varying mobilities cover many orders of magnitude. The two universal ac conductivities are similar, but not identical; both are examples of unusual non-power-law universalities. It is argued that ac universality reflects an underlying percolation determining dc as well as ac conductivity in the extreme disorder limit. Three analytical approximations to the universal ac conductivities are presented and compared to computer simulations. Finally, model predictions are briefly compared to experiment.
Assessing the effects of low dose aspirin on uricacid and renal function in healthy adults

Objective: To evaluate the effects of low daily aspirin doses on uric acid (UA) level and renal functions in healthy adults. Methods: Healthy adults were randomized to receive 100 mg (n= 33), or 300 mg (n = 31) aspirin daily for one month. Laboratory tests included measurement of blood urea nitrogen (BUN), serum creatinine, and uric acid (UA) levels. Urine creatinine, urea and uric acid excretion were measured in a 24 h collection of urine, 24 hours urine uric acid, creatinine clearance (Ccr), were measured at baseline and then after 4 weeks of therapy. Results: After 4 weeks of therapy, 100 and 300 mg/d dosage, aspirin caused a 7% and 12% decrease in the rate of UA excretion respectively (P< 0.05). Patients at the dosage 300 mg/d but not the 100mg/day had an increase in serum levels of uric acid (UA), creatinine and urea with a significant decrease in 24 hour creatinine clearance and urinary urea excretion (P<0.05) when compared with the baseline. Conclusion: Because of the effects of 300 mg dose aspirin, in the lowering of kidney function and the potential of aspirin to cause dose-dependent impairment of renal function, patients taking low-dose aspirin therapy should be monitored for the development of impaired renal function.
Elemental quotas and physiology of a southwestern Pacific Ocean plankton community as a function of iron availability

The rate of carbon fixation by phytoplank- ton in marine surface waters is often tied to the supply of growth-limiting nutrients such as iron (Fe). While average cellular requirements and ratios for various elements are well known in the literature, especially through laboratory culture work, the plasticity of these relationships in natural plankton communities has been less explored. To gauge how changes in the biological availability of dissolved Fe might influence cellular nutrient ratios of marine phytoplankton (and thus their physiology), we carried out incubation assays during a research expedition off the east coast of New Zealand. Trace-metal clean collection of plankton communities were amended with a continuum of concentrations of either Fe (as FeCl3) or desferroxamine B (to reduce bioavailable Fe) and then maintained for 72 h under in situ conditions. Along with standard assays (Fv/Fm, chlorophyll, nutrient drawdown), we measured ele- mental ratios in the bulk community by inductively coupled plasma mass spectrometry and within individ- ual plankton using synchrotron X-ray fluorescence. Our observations demonstrate that changes in the physiological ecology of the community (biomass, photosynthetic efficiency) were mirrored in changes in elemental ratios, including a 3-fold change in Fe stoi- chiometry and a 13-fold change in Zn stoichiometry when Fe-replete and Fe-depleted communities were compared. We present this information in consideration of the hypothesis that flexibility in elemental quotas influences the interactions between nutrient availabil- ity and planktonic physiological status, subsequently altering C flow through marine surface waters.

Taxonomy of the lesser jerboa Jaculus jaculus (Dipodidae,Rodentia) based on allozymic and morphological variation

The lesser Egyptian jerboa Jaculus jaculus, is a member of the subfamily Dipodinae, known to have a number of subspecies. Previous studies of J. jaculus from North Africa found various morphological forms of unknown taxonomic status, which are frequently grouped into two taxa: J. jaculus and J. deserti. We assessed the taxonomic status of this taxon in Tunisia using allozymic (phylogenetic analysis of 23 genetic loci encoding 16 enzymatic proteins) and morphological (multivariate analysis of 13 craniodental characters) analyses of 136 J. jaculus specimens collected from seven localities within its distribution range. Allozymic analysis clearly indicated the existence of two distinct groups of J. jaculus, with a mean genetic distance (D) value of 0.99 and F_(ST)=0.52. Individuals within the two groups did not show any obvious geographical structuration, even within the Matmata locality which represents the meeting point for the two groups where they were found in sympatry. Additionally, morphometric analysis of 13 craniodental characters was clearly separated the two groups. These results were obtained over a very restricted area of the total distribution of J. jaculus and strongly suggest the occurrence of two separate and often sympatric species within the currently accepted J. jaculus in Tunisia: J. jaculus and J. deserti .
Air Q Blocker LMA in Patients Undergoing Laparoscopic Cholecystectomy-A Pilot Study

Background: To evaluate the performance characteristics of Air Q Blocker laryngeal mask airway in patients undergoing laparoscopic cholecystectomy laying importance on the oropharyngeal leak pressure of the device as an indicator of the safety and efficacy of its seal. Material and Methods : After obtaining clearance from the local ethical committee, this pilot study was conducted on 40 adult , ASA I-II grade patients posted for elective laparoscopic cholecystectomy under general anaesthesia. Anaesthesia technique was standardized for all patients. Air Q Blocker of appropriate size was inserted and its position was confirmed. Intraabdominal pressures and flow rates were kept at 12 mm Hg and 2.5 L/min maximum respectively. The primary outcome measured was oropharyngeal leak pressure and its margin of safety. Secondary outcomes included the time for insertion, attempts of insertion, ease of nasogastric tube placement, haemodynamic parameters, ventilation characteristics and postoperative complications. Result: The success rate of first attempt insertion was 95 %. Mean time for insertion was 13.70 ±3.05 seconds. Success of 1st attempt Gastric Tube Insertion was (95 % ). Mean oropharyngeal leak pressure was 33.76 cm H2O. Mean level of margin of safety was 11.14 cm H2O. 10 % of patients had a sore throat and 5% of patients had mild airway trauma. Ventilation was adequate in all patients, minimal haemodynamic variation and there was no incidence of postoperative complications. Conclusion: A properly positioned Air Q Blocker proved to be a suitable and safe device for airway management in fasting, adult patients undergoing elective laparoscopic surgeries. Despite of high airway pressures, it provided effective pulmonary ventilation without gastric distention, regurgitation, and aspiration.
Contrasting medium and genre on Wikipedia to open up the dominating definition and classification of geoengineering

Geoengineering is typically defined as a techno-scientific response to climate change that differs from mitigation and adaptation, and that includes diverse individual technologies, which can be classified as either solar radiation management or carbon dioxide removal. We analyse the representation of geoengineering on Wikipedia as a way of opening up this dominating, if contested, model for further debate. We achieve this by contrasting the dominating model as presented in the encyclopaedic article texts with the patterns of hyper-link associations between the articles. Two datasets were created tracing the geoengineering construct on Wikipedia, shedding light on its boundary with its context, as well as on its internal structure. The analysis shows that the geoengineering category tends to be associated on Wikipedia primarily with atmospheric solar radiation management rather than land-based carbon dioxide removal type technologies. The results support the notion that the dominant model of defining and classifying geoengineering technology has been beneficial for solar radiation management type technologies more than for land-based carbon dioxide removal ones. The article also demonstrates that controversy mapping with Wikipedia data affords analysis that can open up dominating definitions and classifications of technologies, and offer resistance to their frequent naturalising and decontextualising tendencies. This work is in line with recent work on digital sociology, but the article contributes a new methodology and reports on the first empirical application of controversy mapping using Wikipedia data to a technology.
FUTURE TRUST FORECAST IN OPEN MOBILE AGENT ENVIRONMENT

Open Mobile Agent Environments, where entities can join and leave the system at any time, are particularly susceptible to the attacks of malicious entities. Hence intense studies of potential solutions of related problems are needed, including proper and speedy estimation of node’s trustworthiness. We propose an optimisation method for trust estimation (reputation forecasting) and apply it to two known reputation metrics (eBay and BetaSystem). We show results of simulations comparing the effectiveness of reputation discovery using the original algorithm and the optimized (forecasting reputation) one.
Prosodic word deletion in coordinate structures

Prosodic word deletion in partially identical coordinate structures (DUI) is a rather general phenomenon across languages. In this paper, new data is presented that contributes to a cross-linguistic understanding of the deletion process. Its phonological nature is supported by an array of prosodic requirements on the deleted unit, its counterpart, the remnant, and the way the coordinate sequence is prosodically phrased, showing that a pure morpho-syntactic analysis of DUI is unattainable. On the other hand, it is also shown that syntax constrains DUI as well. These properties are argued to be general and the cross-linguistic variation found is shown to result from prosodic differences that the languages independently display. It is further argued that DUI is fundamentally different from syntactic ellipsis phenomena. The account proposed places this process at the syntax-phonology interface without any further addition to constrained models of syntax-phonology interaction.
Achieving Wide Band Gaps and a Band Edge Laser Using Face-Centered Cubic Lattice by Holography

Complete band gaps (CBGs) is an important research topic in the study of photonic crustals (PCs). In 1990, K.M. Ho et al. demonstrated theoretically that a diamond structure possesses CBGs [1], since then, great interests were attracted in fabricating three-dimensional (3D) PCs in order to obtain CBGs. Several methods were reported, and CBGs were achieved in the range of microwave or sub-microwave. Theoretical analysis shows that although CBGs can be obtained by diamond structure, a strict condition has to be satisfied, i.e., the modulation of refractive index of the material used should be larger than 2.0 [2, 3]. So, many scientists paid their attention to find the materials with high the refractive index. Some of them tried to fill the templates with high refractive index materials to increase the modulation of the refractive index [4-6], and CBGs were obtained. However, the achieved CBGs in 3D PCs were mostly in microwave and infrared regions [5, 7-9]. Holography is a cheap, rapid, convenient, and effective technique for fabricating 3D structures. In 1997, holographic technique was introduced to fabricate the face centered cubic (fcc) structure [10]. Campbell et al. fabricated fcc structure in terms of holographic lithography [11]. Several authors reported their works in this topic [2, 3, 7, 12]. Toader and John also showed theoretically a five-beam “umbrella” configuration for synthesis of a diamond photonic crystal [13]. Because both the value and modulation of the refractive index of the holographic recording materials are commonly low so that the PCs made directly by holography would not have CBGs. For example, the epoxy photoresist is generally used in holographic lithography [11, 14-16] , but, its refractive index is n=1.6 which is a little bit too low. They may, however, be used as templates for the production of inverse replica structures by, for example, filling the void with high refractive index and burning out or dissolving the photoresist [11], and a good work was done by D.C.Meisel [17] etc. But, to find the materials with large refractive index is not easy, and the special techniques needed are very complicated and expensive. It limits the applications of PCs, especially for industrial productions. Although band gaps can be broadened by means of multi-structures [18], CBGs in visible range had not yet been achieved, especially by using the materials with low refractive index. Therefore, it is a big challenge to fabricate 3D PCs possessing CBGs in visible range by using
