Henry E. Kyburg, Jr and Choh Man Teng
- Abstract
Coping with uncertainty is a necessary part of ordinary life and is crucial to an understanding of how the mind works. For example, it is a vital element in developing artificial intelligence that will not be undermined by its own rigidities. There have been many approaches to the problem of uncertain inference, ranging from probability to inductive logic to nonmonotonic logic. Thisbook seeks to provide a clear exposition of these approaches within a unified framework. The principal market for the book will be students and professionals in philosophy, computer science, and AI. Among the special features of the book are a chapter on evidential probability, which has not received a basic exposition before; chapters on nonmonotonic reasoning and theory replacement, matters rarely addressed in standard philosophical texts; and chapters on Mill's methods and statistical inference that cover material sorely lacking in the usual treatments of AI and computer science.

Data quality is a prime concern for many tasks in learning and induction. We proposed in a previous paper a noise correction mechanism called polishing, which exploits the interdependence between the different components of a data set, to identify the noisy values and their appropriate replacements. The design of a sound and informative metric for evaluating the effectiveness of a noise correction scheme turned out to be non-trivial. We motivate here a number of classifier dependent measures and proximity measures, each focusing on a different aspect of the corrected data and the associated classifier. We report on some extended experimentation with polishing, as measured by the proposed metrics. The results suggested that polishing is able to repair a corrupted data set to some extent, and the metrics we devised appear to be reasonable.

When we work with information from multiple sources, the formats of the knowledge bases may not be uniform. It is desirable to be able to combine a knowledge base of default rules with one containing autoepistemic formulas. “Cooperative combination” refers to the integration of knowledge bases in different formats, in a way that retains as much of the individual characteristics of the component formalisms as possible. Previous work on relating default logic and autoepistemic logic mostly imposes some constraints on autoepistemic logic, and thus is not suitable for combining the two logics. We first present a fixed point formulation of autoepistemic logic analogous to that of default logic. Then we introduce a possible world framework with a partition structure, which corresponds to our intuitive notion of accessibility as linking alternate “possible” worlds. We show that both default logic and autoepistemic logic can be characterized using this common framework, which is important for developing a semantics applicable to the two logics, both separately and combined. We show one way of cooperatively integrating the two logics, and provide both a syntactic fixed point and a semantic possible partition sequence characterization.

260. Automatic Discovery of Attack Messages and Pre- and Post-Conditions for Attack Graph Generation.
- Author

Carvalho, Marco and Choh Man Teng
- Abstract
Network attack graphs are directed graph-representations of possible attack paths and vulnerabilities in a computer network. Each attack path is a sequence of steps taken by an attacker to achieve one or more goals in the target system. While there are some variations in the representations of the graph proposed by different researchers, typically the edges represent possible actions (or exploits) available to an attacker, and vertices represent the possible states for the system and applications. Attack graphs are often manually created or, less often, automatically generated from a set of attack models and detailed information about the network topology and its applications. There have been several proposals for the automatic identification and representation of attack models, but they all rely on some prerequisite knowledge of the pre- and post-conditions for the different attack steps. A pre-condition may include requirements such as "attacker must have root privileges", while a post-condition defines the state of the system after an action is taken. In this paper we propose algorithms for the automatic identification of likely pre- and post-conditions that can be used for the generation of attack graphs. Our approach extracts such candidate conditions from observational data. By monitoring low-level events on multiple network nodes, in correlation with detected anomalies or attacks, our approach can automatically and unobtrusively identify the attributes of interest for the attack model required for attack graph generation. The paper provides a brief review of the requirements for automatic attack graph generation, and describes our proposed approach in detail. We also present preliminary simulation results for the automatic discovery of attack messages and their pre- and post-conditions, in a simplified fully connected network environment.

- Abstract
In this study, four strains of Japanese Encephalitis Virus (JEV) were isolated from the cerebrospinal fluid of aborted fetuses or stillborn piglets collected randomly from a number of piggeries in central China. The E genes were cloned by RT–PCR and sequenced. Phylogenetic analysis was performed with 48 JEV isolates previously reported in China and other countries, and showed that all four isolates can be classified into the subcluster of genotype III. The results strongly suggest that the genotype III of JEV is the major variant currently circulating in the swinery of central China. [ABSTRACT FROM AUTHOR]

Recently, the "multiple islands per read head" model has been proposed for patterned media storage systems. In this paper, we investigated the applications of nonbinary low-density parity-check (LDPC) codes to such channels. Different nonbinary LDPC codes are designed for different read head models. We have also investigated the iterative decoding/detection algorithms for such coded systems. Simulation results show that significant performance improvements in terms of the symbol error rate (SER) can be achieved, especially when iterative decoding/detection algorithms are implemented, whereby soft extrinsic messages are exchanged between the belief-propagation-based decoder for the nonbinary LDPC code and the Bahl-Cocke-Jelinek-Raviv (BCJR)-based detector for the patterned media storage channel.

In this paper, the infectivity and propagation of two attenuated infectious bursal disease virus (IBDV) strains in DT40 cells were investigated. The results showed that both of the tested strains, TAD and HN
3 , directly infect and proliferate in DT40 cells, requiring no adaptive passages. Unexpectedly, IBDV can be rapidly propagated and continuously harvested at high titers for a long time, accompanied by the rapid growth of host cells and showing no increase in pathogenicity. Our results provide further support to suggest that DT40 cells can be used as an ideal model for studying IBDV pathogenesis. Additionally, the DT40 cell line could also serve as a potential system for commercial IBDV vaccine preparation. [ABSTRACT FROM AUTHOR]- Published

STATISTICS , *NONMONOTONIC logic , *PROBABILITY theory , *LOGIC , *INFERENCE (Logic) - Abstract
Classical statistical inference is nonmonotonic: obtaining more evidence or obtaining more knowledge about the evidence one has can lead to the replacement of one statistical conclusion by another, or the complete withdrawal of the original conclusion. While it has long been argued that not all nonmonotonic inference can be accounted for in terms of relative frequencies or objective probabilities, there is no doubt that much nonmonotonic inference can be accounted for in this way. Here we seek to explore the close connection between classical statistical inference and default logic, treating statistical inference within the framework of default logic, and showing that nonmonotonic logic in general, and default logic in particular, needs to take account of certain features of statistical inference. Default logic must take account of statistics, but at the same time statistics can throw light on problematic cases of default inference. [ABSTRACT FROM AUTHOR]

In order to assess the influence of long-term irrigation of polluted river water on the ecological health of the rice fields in the low reach of Liaohe River Plain, a series of environmental samples and biological samples in rice fields, including sediments, paddy soils, mitten-handed crabs (Eriocheir sinensis), loaches (Misgurnus anguillicaudatu) and frog (Hoplobatrachus tigerinus), were collected from the area far away from industrial zones, and polychlorinated biphenyls (PCBs) and organochlorine pesticides (HCH, DDT, HCB and Mirex) were analyzed by high resolution gas chromatography coupled with high resolution mass spectrometry (HRGC/HRMS). The comparison of pollutant concentrations and profiles verified that the significant contribution of river water irrigation to PCBs contaminations in paddy soils and the mutual influence of organochlorine pesticide contamination between river sediments and paddy soils. Bioaccumulations of PCBs and organochlorine pesticides in mitten-handed crabs and loaches were site-specific, suggested that they were both the good indicators of ecosystem health. Mitten-handed crabs had the highest capacity to accumulate PCBs and organochlorine pesticides, and also they had the strong ability to degrade these pollutants in their bodies, especially for DDT and HCH. The biota-soil accumulation factors (BSAF) of ΣHCH, ΣDDT, Mirex, HCB and ΣPCB in mitten-handed crab were calculated to be 24.5, 15.3, 122.2, 28.1 and 54.6, respectively. In view of the strong bioaccumulation ability, the health risk should be concerned for the cultivation of mitten-handed crabs in paddy fields in the low reach of Liaohe River Plain.

It is estimated that at least one million people die by suicide every year, showing the importance of suicide prevention and detection. In this study, an autoencoder and machine learning model was employed to predict people with suicidal ideation based on their structural brain imaging. The subjects in our generalized q-sampling imaging (GQI) dataset consisted of three groups: 41 depressive patients with suicidal ideation (SI), 54 depressive patients without suicidal thoughts (NS), and 58 healthy controls (HC). In the GQI dataset, indices of generalized fractional anisotropy (GFA), isotropic values of the orientation distribution function (ISO), and normalized quantitative anisotropy (NQA) were separately trained in different machine learning models. A convolutional neural network (CNN)-based autoencoder model, the supervised machine learning algorithm extreme gradient boosting (XGB), and logistic regression (LR) were used to discriminate SI subjects from NS and HC subjects. After five-fold cross validation, separate data were tested to obtain the accuracy, sensitivity, specificity, and area under the curve of each result. Our results showed that the best pattern of structure across multiple brain locations can classify suicidal ideates from NS and HC with a prediction accuracy of 85%, a specificity of 100% and a sensitivity of 75%. The algorithms developed here might provide an objective tool to help identify suicidal ideation risk among depressed patients alongside clinical assessment. [ABSTRACT FROM AUTHOR]

- Abstract
The United States has more than 2.7 million miles of paved roads, of which 94\% are surfaced with asphalt pavement. The resilience and durability of asphalt materials have important consequences for transportation safety. Previous research showed that the porosity, i.e. the fraction of air voids in an asphalt pavement, which is largely influenced by the compaction during the installation process, has a significant influence on the durability of installed asphalt pavements. Therefore, understanding the compaction process of asphalt mixtures has become an essential topic of research. However, the existing modeling approaches are mostly phenomenologically based. Very few studies have focused on developing a physics-based predictive model for the compaction of asphalt mixtures. The development of a physics-based computational model is complicated by the complexity and variability of the asphalt mixture. Asphalt mixtures consist of (1) aggregates (sand, pebbles, and rocks) up to 3\ cm in size, (2) fine aggregate mixtures or FAM consisting of the sand portion of the aggregates, asphalt binder, and other additives coats. During the compaction process, the FAM surrounds the coarser aggregates and ultimately as the mixture cools and solidifies, binds them like glue. The details of each component vary considerably across the country. Part of the difficulty in modeling the compaction of such a complex multiphase mixture is to developing reliable rheology for the constitutive behavior of the mixture. In this study, we developed a multi-scale discrete element method (DEM) model for compaction of asphalt mixtures. The model is anchored by the representation of the asphalt as a two-phase mixture: (1) liquid-like FAM and (2) individual gravel particles. On the macroscopic level, only coarse (large) aggregates are considered in the simulation as non-spherical particles. The interaction between these aggregates is mediated both by the coarse particle properties and the properties of the interstitial fluid-like slurry FAM. We derive the dependence of the FAM rheology to the fluid properties of the asphalt binder and the solid properties of the finer particles using discrete element model (DEM) simulations. We use larger scale DEM simulations with coarse aggregates and the modeled FAM to model the gyratory compaction process of hot mixed asphalt with different viscosity of asphalt binder and different aggregate size distributions. The results of the thesis are comprised of three primary components described in this thesis: (1) the small scale model of particles and fluid which provide more macroscale and particle scale information about slurry flow behavior; (2) the larger multi-scale model framework of the asphalt compaction process itself as a process. The results can provide a systematic method for improving the mix design of asphalt mixtures and the compaction procedures toward a more efficient compaction process.

Sheared particle-fluid systems are ubiquitous in geophysical and manmade structures. We propose a new Distinct Element Method (DEM) model framework for capturing the effect of material properties on the bulk dynamics of these thickly-coated particle-fluid flows. The method combines a Hertz-Mindlin particle contact model to explicitly represent particle material properties and sizes with a classic fluid lubrication model for viscous interactions between coated particles. We show that capturing the small scale interparticle dynamics with Non-Newtonian particle-fluid rheologies that mediate large particle interactions captures large-scale compaction dynamics in asphalt materials. We conclude with a brief discussion of limitations and also how this may be extended to represent similar systems of a wider size distribution such as debris flows.

MicroRNAs (miRNAs) are small non-coding RNAs with profound regulatory roles in many areas of biology, including cancer. MicroRNA 155 (miR-155), one of the extensively studied multifunctional miRNAs, is important in several human malignancies such as diffuse large B cell lymphoma and chronic lymphocytic leukemia. Moreover, miR-155 orthologs KSHV-miR-K12-11 and MDV-miR-M4, encoded by Kaposi's sarcoma-associated herpesvirus (KSHV) and Marek's disease virus (MDV) respectively, are also involved in oncogenesis. In MDV-induced T-cell lymphomas and lymphoblastoid cell lines derived from them, MDV-miR-M4 is highly expressed. Using excellent disease models of infection in natural avian hosts, we showed previously that MDV-miR-M4 is critical for the induction of T-cell lymphomas as mutant viruses with precise deletions were significantly compromised in their oncogenicity. However, these studies did not elucidate whether continued expression of MDV-miR-M4 is essential for maintaining the transformed phenotype of tumor cells. Here using an in situ CRISPR/Cas9 editing approach, we deleted MDV-miR-M4 from the MDV-induced lymphoma-derived lymphoblastoid cell line MDCC-HP8. Precise deletion of MDV-miR M4 was confirmed by PCR, sequencing, quantitative RT-PCR and functional analysis. Continued proliferation of the MDV-miR-M4-deleted cell lines demonstrated that MDV miR-M4 expression is non-essential for maintaining the transformed phenotype, despite its initial critical role in the induction of lymphomas. Ability to examine the direct role of oncogenic miRNAs in situ in tumour cell lines is valuable in delineating distinct determinants and pathways associated with the induction or maintenance of transformation in cancer cells and will also contribute significantly to gain further insights into the biology of oncogenic herpesviruses.

- Abstract
Aim: To discuss the long-term postoperative results of bilateral lateral rectus recession (BLR) and unilateral lateral rectus recession-medial rectus resection (RR) in therapy of intermittent exotropia., Methods: We retrospectively analyzed 213 cases of intermittent exotropia who underwent surgery between 2008 and 2010. The patients were grouped into BLR group and RR group. Motor outcomes were divided into three groups on the basis of the angle of deviation after surgery: overcorrection (esotropia/phoria >5(Δ)), orthophoria (esotropia/phoria ≤5(Δ) to exotropia/phoria ≤10(Δ)), and undercorrection/recurrence (exotropia/phoria >10(Δ)). Titmus test was used to evaluate stereoacuity, the stereoacuity <800s of arc meaned the patients had stereopsis. Surgical outcome including motor criteria and sensory status were compared at postoperative 6, 12, 24mo and at 36mo examination between groups., Results: At 12, 24mo after surgery, the motor outcomes had no difference (P>0.05) between groups. However, the motor outcomes at 6, 36mo were signally different in each group, indicating the success rate in RR group at 6mo was higher than that in BLR group (83.02% vs 82.24%, P<0.05) but the result was contrary at the 3y examination (60.75% vs 43.40%, P<0.05). No statistical significance were found in the sensory outcomes between the groups at mean of 3.7y follow-up., Conclusion: The motor outcomes in RR group were better than in BLR group at 6mo after surgery, while the 3y outcomes were better in BLR group. This may be due to the recurrence rate of the BLR was lower than the RR group's.

- Abstract
Objective: To analyze the surveillance data on hemorrhagic fever with renal syndrome (HFRS) including the epidemiological characteristics and trend of the disease, in 2010., Methods: Descriptive methods were conducted to analyze the surveillance data in 2010 which were collected from the internet-based National Notifiable Disease Reporting System and 40 HFRS sentinels in China., Results: There were 9526 cases of HFRS reported in 2010 in the country with an annual morbidity of 0.71/10(5), which was higher than that reported in 2009. And the case fatality rate in 2010 was 1.24%. During the year 2010, most cases were reported in spring and autumn-winter season, with November as the peak month. The proportion of cases reported in autumn-winter season was higher than that in spring. The number of cases reported in males was higher than that in females among all the age groups, and similar pattern of mortality could be seen in most of the age groups. The percentage of cases over 60 years old had increased in recent years. Farmers were still under the highest risk. Density and the virus-carrying rate of animal hosts, as well as the infection rate were relatively stable and similar to the previous findings. As to the prevailing species, Apodemus agrarius and Rattus norvegicus were still the most common and leading animal hosts. However, the dominant species in sentinel of Yunnan were Rattus flavipectus and Eothenomys miletus respectively, and a new hantavirus called LUXV was found, namely Eothenomys miletus., Conclusion: HFRS cases were widely distributed in most provinces of China, but cases mainly focus on certain areas and present the nature of aggregation. The risk of outbreak could not be ruled out for variety of factors. Population characteristics and seasonal fluctuation had been changing.
