Physical layer security in 5G wireless networks for data protection

The fifth generation (5G) network would be a key facilitator to keeping up to the future wireless application demands such as ultra-high data rate, ultra-wide radio coverage, ultra — low latency, large number of devices connected etc. Security is a crucial issue in the 5G network as wireless transmissions have the innate quality of vulnerability towards unfriendly breach or hacks. In this paper, security issue in the 5G network, specifically the physical layer security, has been analyzed. The physical layer safeguards confidentiality of data by capitalizing on the inherent random nature of the communication medium. There are various technologies prevalent in 5G, the three most prominent ones-heterogeneous networks, massive multiple-input multiple-output, and millimeter wave have been considered and discussed. The potential areas for improvement and issues in each of the technologies have been identified and analyzed. This analysis would help in better understanding of physical layer security in the future.
Aesthetics and Experience in Music Performance

Drawing upon a wide range of scholarly enquiry into early music, queer musicology, ethnomusicology, performance practice, music education and technology, Aesthetics and Experience in Music Performance provides a lively forum for the articulation of varied perspectives on the role of music, its interpretation and function in contexts supported by those who practice or experience it. The formal and shorter discussion papers included in this scholarly collection were presented at the National Workshop of the Musicological Society of Australia, held at the University of Queensland, Brisbane in October 2003. The themes of aesthetics and experience are central to this publication and each paper engages in a scholarly dialogue on the technical, expressive and embodied aspects of performance. The papers included in this publication bring together the research of a wide community of scholars (e.g., musicologists, anthropologists, ethnomusicologists and linguists) working in the field of performance studies and collectively reflect the musicological issues being debated in Australia today.
Embodied Rhythm Interventions for Children with Autism Spectrum Disorders (ASDs)

The current randomized controlled trial compared the effects of novel, embodied, rhythm interventions music and robotic with those of a standard-of-care, stationary, academic intervention on the social communication, behavioral, and motor skills of 36 children with Autism Spectrum Disorders (ASDs) between 5 and 12 years of age. Children were matched on age, level of functioning, and services received prior to randomization. The study lasted for 10 weeks with the pretest and posttest sessions conducted during the first and last weeks of the study. Training was provided in the intermediate 8 weeks, with 2 sessions provided each week. Between-group differences and within-group changes in social attention and social verbalization skills, repetitive/problem behaviors, and motor performance were assessed using task-specific tests within the training context and standardized tests outside the training context. The music-based context afforded greater social monitoring and spontaneous initiation of engagement compared to the robotic and academic contexts. The robotic context promoted fixation on robots and greater scripting and self-directed vocalizations, limiting opportunities for interactions with social partners. Due to the novelty of the training activities, the movement groups initially demonstrated greater negative behaviors compared to the academic group. Although the academic group afforded responsive verbalization, children spent a majority of time in non-social object-based engagement. In terms of taskspecific training effects, the music group showed an increase in duration of social verbalization and reductions in imitation error scores and frequency of negative behaviors across weeks. Although the robot group demonstrated small improvements in imitation scores, children demonstrated a decrease in engagement with the context across training sessions. The academic group improved their fine motor imitation scores, but did not demonstrate any changes in social attention, social verbalization, and repetitive behaviors across sessions. In terms of generalized changes in skills, the music and academic Sudha Madhav Srinivasan – University of Connecticut, 2014 groups demonstrated improvements in responsive joint attention following training. Consistent with training demands, the movement groups improved gross motor skills, whereas the academic group improved fine motor skills, on a standardized test of motor performance. Overall, movement-based music contexts hold promise in remediating the impairments associated with autism and warrant future
Preliminary Characterisation of Tumor Necrosis Factor Alpha and Interleukin-10 Responses to Chlamydia pecorum Infection in the Koala (Phascolarctos cinereus)

Debilitating infectious diseases caused by Chlamydia are major contributors to the decline of Australia's iconic native marsupial species, the koala (Phascolarctos cinereus). An understanding of koala chlamydial disease pathogenesis and the development of effective strategies to control infections continue to be hindered by an almost complete lack of species-specific immunological reagents. The cell-mediated immune response has been shown to play an influential role in the response to chlamydial infection in other hosts. The objective of this study, hence, was to provide preliminary data on the role of two key cytokines, pro-inflammatory tumour necrosis factor alpha (TNFα) and anti-inflammatory interleukin 10 (IL10), in the koala Chlamydia pecorum response. Utilising sequence homology between the cytokine sequences obtained from several recently sequenced marsupial genomes, this report describes the first mRNA sequences of any koala cytokine and the development of koala specific TNFα and IL10 real-time PCR assays to measure the expression of these genes from koala samples. In preliminary studies comparing wild koalas with overt chlamydial disease, previous evidence of C. pecorum infection or no signs of C. pecorum infection, we revealed strong but variable expression of TNFα and IL10 in wild koalas with current signs of chlamydiosis. The description of these assays and the preliminary data on the cell-mediated immune response of koalas to chlamydial infection paves the way for future studies characterising the koala immune response to a range of its pathogens while providing reagents to assist with measuring the efficacy of ongoing attempts to develop a koala chlamydial vaccine.
Small-Molecule Screening Using a Whole-Cell Viral Replication Reporter Gene Assay Identifies 2-{[2-(Benzoylamino)Benzoyl]Amino}-Benzoic Acid as a Novel Antiadenoviral Compound

ABSTRACT Adenovirus infections are widespread in society and are occasionally associated with severe, but rarely with life-threatening, disease in otherwise healthy individuals. In contrast, adenovirus infections present a real threat to immunocompromised individuals and can result in disseminated and fatal disease. The number of patients undergoing immunosuppressive therapy for solid organ or hematopoietic stem cell transplantation is steadily increasing, as is the number of AIDS patients, and this makes the problem of adenovirus infections even more urgent to solve. There is no formally approved treatment of adenovirus infections today, and existing antiviral agents evaluated for their antiadenoviral effect give inconsistent results. We have developed a whole cell-based assay for high-throughput screening of potential antiadenoviral compounds. The assay is unique in that it is based on a replication-competent adenovirus type 11p green fluorescent protein (GFP)-expressing vector (RCAd11pGFP). This allows measurement of fluorescence changes as a direct result of RCAd11pGFP genome expression. Using this assay, we have screened 9,800 commercially available small organic compounds. Initially, we observed approximately 400 compounds that inhibited adenovirus expression in vitro by ≥80%, but only 24 were later confirmed as dose-dependent inhibitors of adenovirus. One compound in particular, 2-{[2-(benzoylamino)benzoyl]amino}-benzoic acid, turned out to be a potent inhibitor of adenovirus replication.
Is a Companion a Distinctive Kind of Relationship with a Machine?

I start from a perspective close to that of the EC COMPANIONS project, and set out its aim to model a new kind of human-computer relationship based on long-term interaction, with some tasks involved although a Companion should not be inherently task-based, since there need be no stopping point to its conversation. Some demonstration of its functionality will be given but the main purpose here is an analysis of what it is people might want from such a relationship and what evidence we have for whatever we conclude. Is politeness important? Is an attempt at emotional sympathy important or achievable? Does a user want a consistent personality in a Companion or a variety of personalities? Should we be talking more in terms of a "cognitive prosthesis (or orthosis)? "---something to extract, organize, and locate the user's knowledge or personal information---rather than attitudes?
Paraphrasing Towards Better Search by Incorporating Coordinate Relationship

We propose a method to acquire paraphrases from the Web in accordance with a given sentence query. For example, consider the query “Guavas are rich in vitamin c”. Its paraphrases are expressions or sentences that convey the same meaning but are different syntactically, such as “Guavas are well known for their high concentration of vitamin c”, or “Guavas are very high in vitamin c”. We aim at improving the poor performance of querying the Web by long queries, especially sentence queries, since they often result in failure. By issuing paraphrase queries to the Web, users are able to gather more search results about the given sentence query.
PFS: Probabilistic filter scheduling against distributed denial-of-service attacks

Distributed denial-of-service (DDoS) attacks continue to pose an important challenge to current networks. DDoS attacks can cause victim resource consumption and link congestion. A filter-based DDoS defense is considered as an effective approach, since it can defend against both attacks: victim resource consumption and link congestion. However, existing filter-based approaches do not address necessary properties for viable DDoS solutions: how to practically identify attack paths, how to propagate filters to the best locations (filter routers), and how to manage many filters to maximize the defense effectiveness. We propose a novel mechanism, termed PFS (Probabilistic Filter Scheduling), to efficiently defeat DDoS attacks and to satisfy the necessary properties. In PFS, filter routers identify attack paths using probabilistic packet marking, and maintain filters using a scheduling policy to maximize the defense effectiveness. Our experiments show that PFS achieves 44% higher effectiveness than other filter-based approaches. Furthermore, we vary PFS parameters in terms of the marking probability and deployment ratio, and find that 30% marking probability and 30% deployment rate maximize the attack blocking rate of PFS.
The Single Dynamin-like Protein of Trypanosoma brucei Regulates Mitochondrial Division and Is Not Required for Endocytosis*

Members of the evolutionarily conserved dynamin-related GTPase family mediate numerous cellular membrane remodeling events. Dynamin family functions include the scission of clathrin-coated pits from the plasma membrane, mitochondrial fission, and chloroplast division. Here we report that the divergent eukaryote Trypanosoma brucei possesses a single dynamin family gene, which we have designated TbDLP. Furthermore, a single dynamin family gene is also found in the Leishmania major and Trypanosoma vivax genomes, indicating that this is a conserved feature among the kinetoplastida. TbDLP is most homologous to the DMN/DRP family of dynamin-like proteins. Indirect immunofluorescence microscopy reveals that TbDLP is distributed in punctate structures within the cell that partially co-localize with the mitochondrion when labeled with MitoTracker. To define TbDLP function, we have used RNA interference to silence the TbDLP gene. Reduction of TbDLP protein levels causes a profound alteration in mitochondrial morphology without affecting the structure of other membrane-bound compartments, including the endocytic and exocytic apparatus. The mitochondrial profiles present in wild type trypanosomes fuse and collapse in the mutant cells, and by electron microscopy the mitochondria are found to contain an accumulation of constriction sites. These findings demonstrate TbDLP functions in division of the mitochondrial membrane. Most significantly, as TbDLP is the sole member of the dynamin family in this organism, scission of clathrin-coated pits involved in protein trafficking through the highly active endocytic system in trypanosomes must function in the absence of dynamin. The evolutionary implications of these findings are discussed.
Spiny neurons of amygdala, striatum, and cortex use dendritic plateau potentials to detect network UP states

Spiny neurons of amygdala, striatum, and cerebral cortex share four interesting features: (1) they are the most abundant cell type within their respective brain area, (2) covered by thousands of thorny protrusions (dendritic spines), (3) possess high levels of dendritic NMDA conductances, and (4) experience sustained somatic depolarizations in vivo and in vitro (UP states). In all spiny neurons of the forebrain, adequate glutamatergic inputs generate dendritic plateau potentials (“dendritic UP states”) characterized by (i) fast rise, (ii) plateau phase lasting several hundred milliseconds, and (iii) abrupt decline at the end of the plateau phase. The dendritic plateau potential propagates toward the cell body decrementally to induce a long-lasting (longer than 100 ms, most often 200–800 ms) steady depolarization (∼20 mV amplitude), which resembles a neuronal UP state. Based on voltage-sensitive dye imaging, the plateau depolarization in the soma is precisely time-locked to the regenerative plateau potential taking place in the dendrite. The somatic plateau rises after the onset of the dendritic voltage transient and collapses with the breakdown of the dendritic plateau depolarization. We hypothesize that neuronal UP states in vivo reflect the occurrence of dendritic plateau potentials (dendritic UP states). We propose that the somatic voltage waveform during a neuronal UP state is determined by dendritic plateau potentials. A mammalian spiny neuron uses dendritic plateau potentials to detect and transform coherent network activity into a ubiquitous neuronal UP state. The biophysical properties of dendritic plateau potentials allow neurons to quickly attune to the ongoing network activity, as well as secure the stable amplitudes of successive UP states.
Supervised multi-modal topic model for image annotation

Multi-modal topic models are probabilistic generative models where hidden topics are learned from data of different types. In this paper we present supervised multi-modal latent Dirichlet allocation (smmLDA), where we incorporate class label (global description) into the joint modeling of visual words and caption words (local description), for image annotation task. We derive variational inference algorithm to approximately compute posterior distribution over latent variables. Experiments on a subset of LabelMe dataset demonstrate the useful behavior of our model, compared to existing topic models.
Raising the Stakes: Writing about Witchcraft on Wikipedia

WlKIALITY, Wikimania, WikiGnomes, WikiTrolls, Wikibots, Wikipediaholism. all these neologisms have been coined in recent years to talk about Wikipedia, the online, open-source encyclopedia.1 Comedy Central's Steven Colbert, in a recent interview with Wikipedia's founder Jimmy Wales, quipped, "Wikipedia is the first place I go for knowledge, or when I want to create it. "2 As professors, we have all encountered this resource, either in student footnotes or as the first hit in our own "googling. " While the knee-jerk reaction among many educators is to discourage sharply student use of Wikipedia, the goal of the project described in this article was to craft a pedagogical approach that incorporated student-contribution to Wikipedia in order to teach History methods students how to be historians. In this project, History 400W students contributed to or created new Wikipedia entries on witchcraft and magic accusations from the Greco-Roman period through Colonial America.3 Student learning goals included researching and writing about a specific historical topic, recognizing the relative value of various resources for historical research (including Wikipedia), contributing to high-stakes historical discourse, understanding and constructing historiography, and sharing the process of that discourse with peers. My rubric-based assessment and student survey responses demonstrated that supervised student participation on
Antisense DNAs as multisite genomic modulators identified by DNA microarray

Antisense oligodeoxynucleotides can selectively block disease-causing genes, and cancer genes have been chosen as potential targets for antisense drugs to treat cancer. However, nonspecific side effects have clouded the true antisense mechanism of action and hampered clinical development of antisense therapeutics. Using DNA microarrays, we have conducted a systematic characterization of gene expression in cells exposed to antisense, either exogenously or endogenously. Here, we show that in a sequence-specific manner, antisense targeted to protein kinase A RIα alters expression of the clusters of coordinately expressed genes at a specific stage of cell growth, differentiation, and activation. The genes that define the proliferation-transformation signature are down-regulated, whereas those that define the differentiation-reverse transformation signature are up-regulated in antisense-treated cancer cells and tumors, but not in host livers. In this differentiation signature, the genes showing the highest induction include genes for the G proteins Rap1 and Cdc42. The expression signature induced by the exogenously supplied antisense oligodeoxynucleotide overlaps strikingly with that induced by endogenous antisense gene overexpression. Defining antisense DNAs on the basis of their effects on global gene expression can lead to identification of clinically relevant antisense therapeutics and can identify which molecular and cellular events might be important in complex biological processes, such as cell growth and differentiation.
Estradiol Is Required for a Proper Immune Response to Bacterial and Viral Pathogens in the Female Brain 1

Although the neuroprotective effects of estrogens are well recognized, the exact mechanisms involved in the ability of these sex steroids to protect the cerebral tissue still remain unclear. We tested in our study the hypothesis that estradiol (E2) modulates the innate immune response and expression of genes encoding proteins that a provide survival signal to neurons during infection. Mice received a single systemic or cerebral injection of LPS to trigger a robust but transient inflammatory reaction in the brain. The endotoxin increased transcriptional activation of genes encoding TLR2, TNF-α, and IL-12 in microglial cells. Expression of these transcripts was largely inhibited in the brain of ovariectomized mice at time 24 h postchallenge. E2 replacement therapy totally rescued the ability of the endotoxin to trigger microglial cells and these permissive effects of E2 are mediated via the estrogen receptor (ER)α. Indeed, ERα-deficient mice exhibited an inappropriate reaction to LPS when compared with ERβ-deficient and wild-type mice. This defective innate immune response was also associated with a widespread viral replication and neurodegeneration in ovariectomized mice inoculated intranasally with HSV-2. These data provide evidence that interaction of E2 with their nuclear ERα plays a critical role in the control of cytokines involved in the transfer from the innate to adaptive immunity. This transfer is deviant in mice lacking E2, which allows pathogens to hide from immune surveillance and exacerbates neuronal damages during viral encephalitis.
Bounds on the Price of Anarchy in the KP Model CS 364 A Algorithmic Game Theory , Fall 2004 Paper Reading Project

The topic of this report is the Koutsoupias-Papadimitriou (KP) game-theoretic model for a class of job-scheduling problems. It contains a presentation of the results from the original paper by Koutsoupias and Papadmitriou [1] and a follow-up paper by Czumaj and Vöcking [4]. The papers address the problem of bounding the ratio between the worst case Nash equilibrium and optimum allocation of a set of jobs to a set of machines.
APPLICATION OF OPTIMAL FILTERING FOR STREAMFLOW FORECASTING

This thesis describes the development of a streamflow forecasting model based on the Sacramento Soil Moisture Accounting Model and applies optimal filtering techniques to sequentially update watershed-scale soil moisture state values, to improve streamflow predictions. In general hydrology is the study of the waters of the earth, especially with relation to the effects of precipitation and evaporation upon the occurrence and character of water in streams, lakes and water on or below the land surface. The Sacramento soil moisture accounting model is a hydrologic simulation model developed by the National Weather Service, and used throughout the nation for operational streamflow forecasting. In continuous hydrologic simulation, the accumulation and propagation of errors in estimated values of the model states can degrade the quality of streamflow predictions. This research explores the use of robust filtering techniques to improve streamflow forecasting through state updating of the National Weather Service's Sacramento Soil Moisture Accounting model. Kalman and H-infinity filters are used to update daily estimates of the water content in model states representing watershed-scale soil moisture storage. Updated soil moisture storages are then used to predict daily streamflow. The output from the estimators is then compared with the model output without state updating, the simulation results from the National Weather Service and the observed streamflow. It is seen in this thesis that Kalman and H-infinity filtering provide improved streamflow forecasting compared with existing methods.
Securing Non-Volatile Main Memory

Non-volatile memories provide energy efficiency, tolerance against power failure, and “instant-on” power-up. These memories are likely to replace traditional volatile memory in next-generation laptops and desktops. However, the move to non-volatile memory introduces new vulnerabilities; sensitive data such as passwords and keys residing in main memory persists across reboots and can be probed during hardware suspension. In this paper, we propose a Memory Encryption Control Unit (MECU) to address the vulnerabilities introduced by non-volatile memories. The MECU encrypts all memory transfers between the level 2 cache and main memory. The keys used to encrypt memory blocks are derived from secret information present on removable authentication tokens, e.g., smart card, or other similar secure storage devices. This provides protection against physical attacks in absence of the token. A MECU design is outlined and performance, memory, and security trade-offs considered. We evaluate a MECU-enhanced architecture using the SimpleScalar hardware simulation framework on several hardware benchmarks. The performance analysis shows that we can secure non-volatile memories with minimal overhead—the majority of memory accesses are delayed by less than 1 ns, with limited degradation subsiding within 67μs of a system resume. In effect, we provide zero-cost steady state confidentiality for main memory.
