Micromachined Antennas for Integration with Silicon Based Active Devices

In this thesis micromachined antennas suitable for on-chip integration with silicon based active devices are treated. The emphasis is put on compact 24 GHz antennas, capable of being integrated in commercial SiliconGermanium (SiGe) processes using low temperature post processing micromachining techniques. Antenna types covered are the slot loop antenna, wire loop antenna, meandered dipole and the inverted F antenna. The antennas have been implemented on surface and bulk micromachined low resistivity silicon substrates. It is found that the bulk micromachining method yields antennas with improved efficiency compared to antennas relying on thick dielectrics for reduction of substrate losses. Two patch antennas, suitable for wafer level integration with actice devices are covered. A 60 GHz micromachined aperture coupled patch antenna with a bandwidth of 59-64 GHz is presented. A novel 24 GHz differentially fed patch antenna, manufactured using a thick organic dielectric, is modelled with a modified transmission line method. Low Temperature Co-fired Ceramic (LTCC) and glob-top packaging for integrated antennas is evaluated. Epoxy based glob tops are found to have lower losses than silicone based ones. Finally, crosstalk between the integrated antenna and simple on-chip wire interconnects is analyzed by simulations for slot antennas manufactured in a SiGe process. It is noted that by proper connection of the antenna to the semiconductor substrate a high degree of isolation can be obtained.
Hormone therapy, timing of initiation, and cognition in women aged older than 60 years: the REMEMBER pilot study

Objective:The aim of this pilot study was to assess any trends related to the timing of initiation, and duration, of hormone therapy (HT) use on cognitive function to facilitate the design and power calculations for a future large cohort study entitled Research into Memory, Brain function and Estrogen Replacement (REMEMBER). Design:A total of 428 women aged older than 60 years were recruited from a computer-generated random selection of Adelaide households. Demographic and lifestyle characteristics, and HT use history were recorded and confirmed. The Center for Epidemiological Studies-Depression score was used to assess mood. Cognitive tests were administered measuring global cognition (Mini-Mental State Examination), attention and concentration (Trail Making Test Parts A and B), verbal learning and memory (Consortium to Establish a Registry for Alzheimer's Disease [CERAD] word list immediate and delayed recall), and verbal expression (letter fluency [FAS], category fluency [Animals], and the Boston Naming Test [short form]). Analyses were adjusted for age, education, mood, body mass index, smoking, alcohol intake, and history of cerebrovascular disease. HT use was defined as the use of systemic HT for at least 1 year. Early initiation of HT use was defined as commencement of HT before age 56 years for women with a uterus and ovaries, or within 5 years of a hysterectomy and bilateral oophorectomy. Late initiation of HT use was defined as HT commencing after these times. Results:Early initiators of HT performed better than late initiators on the Mini-Mental State Examination (P = 0.04) and were faster than never users on the Trail Making Test Part A (P = 0.02). Women aged 70-79 years who initiated HT early performed better on the FAS test than never users (P = 0.0008). Late initiators performed worse than never users on the Mini-Mental State Examination (P = 0.09), and on the FAS test in the 60-69 year (P = 0.06) and 80 years and older (P = 0.095) age groups. However, late initiators performed better than never users on the FAS test in the 70-79 year age group (P = 0.015). HT users of less than 11 years (P = 0.09), HT users of more than 11 years (P = 0.04), and estrogen-only users (P = 0.024) performed faster than never users on the Trail Making Test Part A. Combined estrogen plus progestin users performed better than never users on the Boston Naming Test short form (P = 0.07). Conclusions:For some cognitive domains, early initiation of HT from around menopause may be beneficial, and initiation of HT in late menopause may be detrimental. The timing of the initiation of HT seems critical. To fully test these hypotheses and to further examine these trends by route and type of HT regimen in this population, a study size of 2,500 women would be required.
Optimal Layered Multicast Using Network Coding

We investigate the problem of constructing optimal layered multicast for heterogeneous sink nodes using network coding. Taking the flexibility of layered coding into account, we discuss the optimization problem that determines the optimal layers' bit-rates for layered multicast, and express it into a mathematical formulation. Finding that this formulation is nonlinear and difficult to solve, we reduce it into several equivalent optimization problems and further propose a new optimization scheme. Different from the min-favorable algorithm in existing work, this new scheme is a global-favorable one, which determines the optimal layers' bit-rates based on the max-flows of all sink nodes. Simulation results indicate that this new scheme could achieve the maximum of the aggregate throughput for layered multicast.

During the forming operation, the rolling mandrel is moved relative to the forming operation in the axial direction with respect to the workpiece. Furthermore, the invention relates to an apparatus (80) for ironing roller spinning a tubular workpiece with a rolling mandrel which can be arranged in the tubular workpiece, at least one forming roller for being set against and forming the workpiece, and a rotary drive for rotationally driving the workpiece. In the apparatus, the rolling mandrel is mounted such that it can be moved relative to the workpiece in the axial direction during the forming operation.
mDCC_tools: characterizing multi-modal atomic motions in molecular dynamics trajectories

Summary: We previously reported the multi-modal Dynamic Cross Correlation (mDCC) method for analyzing molecular dynamics trajectories. This method quantifies the correlation coefficients of atomic motions with complex multi-modal behaviors by using a Bayesian-based pattern recognition technique that can effectively capture transiently formed, unstable interactions. Here, we present an open source toolkit for performing the mDCC analysis, including pattern recognitions, complex network analyses and visualizations. We include a tutorial document that thoroughly explains how to apply this toolkit for an analysis, using the example trajectory of the 100 ns simulation of an engineered endothelin-1 peptide dimer. Availability and implementation: The source code is available for free at http://www.protein.osaka-u.ac. jp/rcsfp/pi/mdcctools/, implemented in C ++ and Python, and supported on Linux.

Comparative Economic Cycles

The income cycles that have been experienced by six OECD countries over the past 24 years are analysed. The amplitude of the cycles relative to the level of aggregate income varies amongst the countries, as does the degree of the damping that affects the cycles. The study aims to reveal both of these characteristics. It also seeks to determine whether there exists a clear relationship between the degree of damping and the length of the cycles. In order to estimate the parameters of the cycles, the data have been subjected to the processes of detrending, anti-alias filtering and subsampling.
Cuticle integrity and biogenic amine synthesis in C . elegans require the cofactor Tetrahydrobiopterin ( BH 4 )

Tetrahydrobiopterin (BH4) is the natural cofactor of several enzymes widely distributed among eukaryotes, including aromatic amino acid hydroxylases (AAAHs), nitric oxide synthases (NOSs) and alkylglycerol monooxygenase (AGMO). We show here that the nematode Caenorhabditis elegans, which has three AAAH genes and one AGMO gene, contains BH4 and has genes that function in BH4 synthesis and regeneration. Knockout mutants for putative BH4 synthetic enzyme genes lack the predicted enzymatic activities, synthesize no BH4, and have indistinguishable behavioral and neurotransmitter phenotypes, including serotonin and dopamine deficiency. The BH4 regeneration enzymes are not required for steady state levels of biogenic amines, but become rate-limiting in conditions of reduced BH4 synthesis. BH4-deficient mutants also have a fragile cuticle and are generally hypersensitive to exogenous agents, a phenotype that is not due to AAAH deficiency, but rather to dysfunction in the lipid metabolic enzyme AGMO, which is expressed in the epidermis. Loss of AGMO or BH4 synthesis also specifically alters the sensitivity of C. elegans to bacterial pathogens, revealing a cuticular function for AGMO-dependent lipid metabolism in host-pathogen interactions.
Hardness of Online Sleeping Combinatorial Optimization Problems

We show that several online combinatorial optimization problems that admit efficient no-regret algorithms become computationally hard in the sleeping setting where a subset of actions becomes unavailable in each round. Specifically, we show that the sleeping versions of these problems are at least as hard as PAC learning DNF expressions, a long standing open problem. We show hardness for the sleeping versions of Online Shortest Paths, Online Minimum Spanning Tree, Online $k$-Subsets, Online $k$-Truncated Permutations, Online Minimum Cut, and Online Bipartite Matching. The hardness result for the sleeping version of the Online Shortest Paths problem resolves an open problem presented at COLT 2015 (Koolen et al., 2015).
A grid-based mobile agent collaborative virtual environment

This paper describes a large-scale collaborative virtual environment architecture that has the capability of scaling across multiple geographically dispersed resources. The architecture consists of distributed mobile agents working cooperatively in supporting and managing the virtual environments. The mobile agents' tasks include managing persistency and consistency of the virtual worlds, maintaining reliability and efficiency of user interactions, ensuring security and integrity of data and systems, and so on. The mobile agents are autonomous and has the ability of migrating among hosts to maximize resource utilizations. Grid technologies and concepts are introduced into the architecture. These improvements allow the mobile agents to execute and communicate securely in multiple administrative domains. Grid-based scheduling components and polices are integrated to provide intelligent resource optimizations. Furthermore, a better load-balancing can be achieved by utilizing additional or more accurate information like data-user proximity and hosts' workload invariance etc. The result will be a more scalable and robust mobile agent architecture
Types of Aspect Terms in Aspect-Oriented Sentiment Labeling

The paper studies the diversity of ways to express entity aspects in users’ reviews. Besides explicit aspect terms, it is possible to distinguish implicit aspect terms and sentiment facts. These subtypes of aspect terms were annotated during SentiRuEval evaluation of Russian sentiment analysis systems organized in 2014–2015. The created annotation gives the possibility to analyze the contribution of non-explicit aspects to the overall sentiment of a review, their main patterns, and possible use.
EFFECT OF MgO ON CALCINATION AND PROPERTIES OF BELITE-BARIUM CALCIUM SULPHOALUMINATE CEMENT CLINKER WITH Na₂O AND K₂O

The High-quality limestone resources decreased sharply worldwide, and MgO-rich limestone, as an important part of low-quality limestone, is widely used in the cement production because of its low cost. The purpose of this study was to explore the effect of MgO (1-9 wt. %) on the composition and properties of belite-barium calcium sulphoaluminate cement with Na2O and K2O. The experimental results showed that 1 ~ 3 wt. % of MgO in the mineral composition was in favor of calcining and stabilizing the crystal structure of M3–C3S, R–C3S and β-C2S in the cement clinker. Furthermore, the addition of MgO evidently increased the content of R–C3S and β-C2S and goes up to the highest value of 14.47 % and 22.4 % when the addition of MgO reaches 7 wt. %, and the increment of R–C3S and β-C2S was beneficial to improve the mechanical strength of the clinker. The 3d, 7d and 28d compressive strength of the cement with 7 wt. % MgO increased by about 26 %, 7.3 % and 36.2 % than that without MgO. Meanwhile, since the addition of MgO also can promote the formation of C4AF, but has little effect on the formation of C2.75B1. 25A3S – and C3A, the C3A/C4AF ratio present significantly reduction, which indicate that MgO can reduce the viscosity of the liquid phase in the process of calcination. So, the utilization of MgO in low-quality limestone has a great potential to develop low-carbon and sustainable society in producing the belite-barium calcium sulphoaluminate cement.
Zero-error coordinated tracking of multiple lagrange systems using continuous control

In this paper, we study the coordinated tracking problem of multiple Lagrange systems with a time-varying leader's generalized coordinate derivative. Under a purely local interaction constraint, i.e., the followers only have access to their local neighbors' information and the leader is a neighbor of only a subset of the followers, a continuous coordinated tracking algorithm with adaptive coupling gains is proposed. Tracking errors between the followers and the leader are shown to converge to zero. Then, we extend this result to the case when the leader's generalized coordinate derivative is constant. Examples are given to validate the effectiveness of the proposed continuous coordinated tracking algorithms.
Dependability Assessment of Web Service Orchestrations

In this paper, we focus on the reliability and availability analysis of Web service (WS) compositions, orchestrated via the Business Process Execution Language (BPEL). Starting from the failure profiles of the services being composed, which take into account multiple possible failure modes, latent errors, and propagation effects, and from a BPEL process description, we provide an analytical technique for evaluating the composite process' reliability-availability metrics. This technique also takes into account BPEL's advanced composition features, including fault, compensation, termination, and event handling. The method is a design-time aid that can help users and third party providers reason, in the early stages of development, and in particular during WS selection, about a process' reliability and availability. A non-trivial case study in the area of travel management is used to illustrate the applicability and effectiveness of the proposed approach.
Are 'Strong' Primes Needed for RSA

We review the arguments in favor of using so called strong primes in the RSA public key cryptosystem There are two types of such arguments those that say that strong primes are needed to protect against factoring attacks and those that say that strong primes are needed to protect against cycling attacks based on repeated encryption We argue that contrary to common belief it is unnecessary to use strong primes in the RSA cryptosystem That is by using strong primes one gains a negligible increase in security over what is obtained merely by using random primes of the same size There are two parts to this argument First the use of strong primes provides no additional protection against factoring attacks because Lenstra s method of factoring based on elliptic curves ECM circumvents any protection that might have been o ered by using strong primes The methods that strong primes are intended to guard against as well as ECM are probabalistic in nature but ECM succeeds with higher probability For RSA key sizes being proposed now the probability of success of these methods is very low Additionally the newer Number Field Sieve algorithm can factor RSA keys with virtual certainty in less time than these methods Second a simple group theoretic argument shows that cycling attacks are extremely unlikely to be e ective as long as the primes used are large Indeed even probabalistic factoring attacks will succeed much more quickly and with higher probability than cycling attacks
Long-term expansion of epithelial organoids from human colon, adenoma, adenocarcinoma, and Barrett's epithelium.

BACKGROUND & AIMS We previously established long-term culture conditions under which single crypts or stem cells derived from mouse small intestine expand over long periods. The expanding crypts undergo multiple crypt fission events, simultaneously generating villus-like epithelial domains that contain all differentiated types of cells. We have adapted the culture conditions to grow similar epithelial organoids from mouse colon and human small intestine and colon. METHODS Based on the mouse small intestinal culture system, we optimized the mouse and human colon culture systems. RESULTS Addition of Wnt3A to the combination of growth factors applied to mouse colon crypts allowed them to expand indefinitely. Addition of nicotinamide, along with a small molecule inhibitor of Alk and an inhibitor of p38, were required for long-term culture of human small intestine and colon tissues. The culture system also allowed growth of mouse Apc-deficient adenomas, human colorectal cancer cells, and human metaplastic epithelia from regions of Barrett's esophagus. CONCLUSIONS We developed a technology that can be used to study infected, inflammatory, or neoplastic tissues from the human gastrointestinal tract. These tools might have applications in regenerative biology through ex vivo expansion of the intestinal epithelia. Studies of these cultures indicate that there is no inherent restriction in the replicative potential of adult stem cells (or a Hayflick limit) ex vivo.
Confidence estimation for translation prediction

The purpose of this work is to investigate the use of machine learning approaches for confidence estimation within a statistical machine translation application. Specifically, we attempt to learn probabilities of correctness for various model predictions, based on the native probabilites (i.e. the probabilites given by the original model) and on features of the current context. Our experiments were conducted using three original translation models and two types of neural nets (single-layer and multilayer perceptrons) for the confidence estimation task.
VTLN-Based Rapid Cross-Lingual Adaptation for Statistical Parametric Speech Synthesis

Cross-lingual speaker adaptation (CLSA) has emerged as a new challenge in statistical parametric speech syn- thesis, with specific application to speech-to-speech translation. Recent research has shown that reasonable speaker similarity can be achieved in CLSA using maximum likelihood linear transformation of model parameters, but this method also has weaknesses due to the inherent mismatch caused by differing phonetic inventories of languages. In this paper, we propose that fast and effective CLSA can be made using vocal tract length normalization (VTLN), where strong constraints of the vocal tract warping function may actually help to avoid the most severe effects of the aforementioned mismatch. VTLN has a single parameter that warps spectrum. Using shifted or adapted pitch, VTLN can still achieve reasonable speaker similarity. We present our approach, VTLN-based CLSA, and evaluation results that support our proposal under the limitation that the voice identity and speaking style of a target speaker don’t diverge too far from that of the average voice model.
Re-enacted and Spontaneous Conversational Prosody — How Different?

Previous work has shown that read and spontaneous monologues differ prosodically both in production and perception. In this paper, we examine to which extent similar effects can be found between spontaneous and read, or rather re-enacted, dialogues. It is possible that speakers can mimic conversational prosody very well. Another possibility is that in re-enacted dialogues, prosody is actually used less as a communicative de-vice, as there is no need to establish a common ground or to organize the ﬂoor between interlocutors. In our study, we examined spontaneous and read dialogues of equal verbal con-tent. The task-oriented dialogues contained a communicative situation implicitly calling for for a higher speaking rate (time pressure). Our results show that overall, speakers met this conversational demand of increased speaking rate both in the re-enacted and in the spontaneous situation, although we ﬁnd different global speaking rates between conditions. Also, read speech exhibits a lower F0 minimum and, consequently, a larger F0 range than spontaneous conversations, which may be explicable by a lack of active turn taking organization. Summing up, re-enacted conversational prosody resembles many features of spontaneous interaction, but also shows systematic differences.
Outage Probability for Opportunistic Relaying on Multicell Environments

Opportunistic relaying has been shown to be an effective and practical method for implementing the cooperative diversity. However, most of previous works have focused on single cell environments and ignored the effects of interference from neighboring cells. In this paper, opportunistic relaying for cooperative diversity is investigated on multicell environments. We provide a closed form expression for its outage probabil- ity. Simulation results show the outage probability for various considerations on multicell environments. considered a simplified multicell model for the uplink of a TDMA cellular system and provided a closed form expression for the asymptotic per-cell achievable rate over an AWGN channel. In (14), for the decode-and-forward (DF) cooperative diversity, the cooperation between the base station and the mobile terminal was investigated on multicell environments. It improved the uplink per-cell achievable rate on multicell environments over fading channels. This paper investigates opportunistic relaying for the co- operative diversity on multicell environments. We consider a Wyner's simple cellular model which accounts for the intercell interference to simplify the analysis on multicell environments (15). In spite of the simplicity of a Wyner's model, it provides a considerable insight to the realistic cellular systems. Unlike (13) and (14), we analyze the outage probability of the opportunistic relaying and provide a closed form expression for its outage probability on multicell environments over Rayleigh fading channels. Simulation results show the outage probability according to the signal-to-noise ratio (SNR), the interference factor, and the number of available relays. This paper is organized as follows. In Section II, we describe the system model. In Section III, we analyze the opportunistic relaying on multicell environments in terms of the outage probability. In Section IV, the simulation results are shown. Finally, conclusions are drawn in Section V.
