Dual-band dual polarization microstrip antenna (2004)

This paper describes the development of a multilayer dual-band dual-polarized antenna operating at L and C bands with a common aperture. Unlike earlier approaches, slot coupled patches are employed at both bands to reach cross-polarization suppression better than 30 dB. The antenna has been conceived to be used as a basic module in large series-fed arrays featuring light weight, high efficiency and beam scanning. Moreover, by properly scaling the geometry, the antenna can operate at any else pairs of frequencies with a ratio between 3.5-4.5.
Phase Behaviour of Cord Factor and Related Bacterial Glycolipid Toxins (1979)

C-6 esters of methyl alpha-D-glucoside and C-6, C-6' 'diesters of alpha, alpha'-D-trehalose with C18 and C32 threo and erythro mycolic acids (from chemical source) and of C80-erythro-mycolic acid (from natural source) have been synthesized. Esters of a C32 deoxy analogue were prepared as well. Throughout a monolayer study at the air-water interface, these glycolipids are shown to form well organized phases in which the two hydrocarbon chains of mycoloyl residues must be in interaction. Compression isotherms of C32 esters suggested a transition between liquid-expanded and liquid-condensed states. Latent heats Qc and entropy changes delta S associated with these phase transitions as well as the critical temperature at which they occur have been measured. Within the monolayer, the molecular packing of these glycolipids depends on the presence of the hydroxyl group of mycoloyl residues and on its stereochemistry. In particular intermolecular hydrogen bonds between these groups are postulated in the case of the bis(C32-erythro-mycoloyl)-trehalose. On the other hand, short chain C18 esters form fluid phases (t greater than 10 degrees C) whereas very long chain C80 mycoloyl esters of trehalose exist in a condensed state (t = 20 degrees C). These glycolipids were found to interact strongly with dipalmitoylphosphatidylcholine and egg yolk lecithins (3-sn-phosphatidylcholine). Their phase behaviours are discussed in connection with hypotheses concerning the way they can interact with mitochondrial membranes.
New metering and reading techniques based on a modular design concept (1989)

There is a general trend towards a multi-tariff system of measuring electricity at different times during the day or year for direct, short-distance or remote communication. Thanks to modern electronics, these functions can be carried out in an economical and reliable way by the integration of a maximum number of components into special circuits and by using surface-mounted components. This leads to a reduction in dimensions, so that the size of the apparatus is acceptable. The measuring of energy, combined with the above mentioned functions, is effected similarly by a maximum concentration of the metering elements within a high-integration circuit. Since the requirements of the electricity boards are very varied, the separate functions are carried out by complementary modules. These devices transmit locally or remotely messages which enable the customer to regulate his electricity consumption and assist the electricity board in controlling the network load. >
Wave Propagation Models for the Planning of Mobile Communication Networks (1999)

The paper gives a survey on a variety of methods for modelling wave propagation in different mobile communication scenarios. The requirements for predicting fieldstrength level and other relevant parameters are discussed for various mobile communication networks including outdoor and indoor scenarios. Apart from well known and widely used propagation models new approaches with minimised computation time are presented.
A colorimetric assay of 1-aminocyclopropane-1-carboxylate (ACC) based on ninhydrin reaction for rapid screening of bacteria containing ACC deaminase (2011)

Aims: 1-Aminocyclopropane-1-carboxylate (ACC) deaminase activity is an efficient marker for bacteria to promote plant growth by lowering ethylene levels in plants. We aim to develop a method for rapidly screening bacteria containing ACC deaminase, based on a colorimetric ninhydrin assay of ACC. Methods and Results: A reliable colorimetric ninhydrin assay was developed to quantify ACC using heat-resistant polypropylene chimney-top 96-well PCR plates, having the wells evenly heated in boiling water, preventing accidental contamination from boiling water and limiting evaporation. With this method to measure bacterial consumption of ACC, 44 ACC-utilizing bacterial isolates were rapidly screened out from 311 bacterial isolates that were able to grow on minimal media containing ACC as the sole nitrogen source. The 44 ACCutilizing bacterial isolates showed ACC deaminase activities and belonged to the genus Burkholderia, Pseudomonas or Herbaspirillum. Conclusions: Determination of bacterial ACC consumption by the PCR-plate ninhydrin-ACC assay is a rapid and efficient method for screening bacteria containing ACC deaminase from a large number of bacterial isolates. Significance and Impact of the Study: The PCR-plate ninhydrin-ACC assay extends the utility of the ninhydrin reaction and enables a rapid screening of bacteria containing ACC deaminase from large numbers of bacterial isolates.
Hydrophilization of synthetic biodegradable polymer scaffolds for improved cell/tissue compatibility (2013)

Porous scaffolds have been widely used in tissue engineering because they can guide cells and tissues to grow, synthesize extracellular matrix and other biological molecules, and facilitate the formation of functional tissues and organs. Although various natural and synthetic biodegradable polymers have been used to fabricate the scaffolds, synthetic polymers have been more widely used for scaffolds since they have good mechanical strength, reproducible/controllable mechanical-chemical properties, and controllable biodegradation rates. However, the 'hydrophobic character' of common synthetic polymers is considered a limitation for tissue engineering applications because it can lead to a low initial cell seeding density, heterogeneous cell distribution in the scaffold, and slow cell growth due to insufficient absorption/diffusion of cell culture medium into scaffold and lack of specific interaction sites with cells. The hydrophilization of porous synthetic polymer scaffolds has been considered as one of the simple but effective approaches to achieve desirable in vitro cell culture and in vivo tissue regeneration within the scaffolds. In this review paper, representative synthetic biodegradable polymers and techniques to fabricate porous scaffolds are briefly summarized and their hydrophilization techniques to improve cell/tissue compatibility are discussed.

Study on Microbial Deposition and Contamination onto Six Surfaces Commonly Used in Chemical and Microbiological Laboratories (2015)

The worktops in both chemical and microbiological laboratories are the surfaces most vulnerable to damage and exposure to contamination by indoor pollutants. The rate at which particles are deposited on indoor surfaces is an important parameter to determine human exposure to airborne biological particles. In contrast to what has been established for inorganic pollutants, no limit has been set by law for microbial contamination in indoor air. To our knowledge, a comparative study on the effect of surfaces on the deposition of microbes has not been carried out. An evaluation of the microbial contamination of worktop materials could be of crucial importance, both for safety reasons and for the reliability of tests and experiments that need to be carried out in non-contaminated environments. The aim of this study was to evaluate the overall microbial contamination (fungi, mesophilic and psychrophilic bacteria, staphylococci) on six widely used worktop materials in laboratories (glass, stainless steel, fine porcelain stoneware, post-forming laminate, high-performing laminate and enamel steel) and to correlate it with the characteristics of the surfaces. After cleaning, the kinetics of microbial re-contamination were also evaluated for all surfaces.

Studies of Phosphorus Pile‐Up at the Si ‐ SiO2 Interface Using Auger Sputter Profiling (1981)

We have used Auger sputter profiling to investigate in detail the pile‐up of phosphorus at the interface, which occurs during thermal oxidation of heavily doped silicon. We find that, in the early stages of oxidation, the interfacial region acts as a sink for phosphorus. As oxidation proceeds, the "pile‐up" within 50Å of the interface saturates and the phosphorus concentration in the silicon near the interface begins to rise. High temperature nitrogen anneals had little effect on the pile‐up, indicating that existence of the pile‐up cannot be explained by a simple diffusion mechanism. We also observed the pile‐up to be greatly diminished in a heavily boron‐compensated sample. We discuss possible mechanisms which may be responsible for this effect.
An anemometer for UAS-based atmospheric wind measurements (2017)

A low-cost, multi-hole pressure probe for Unmanned Aircraft System airborne flow measurements was developed and tested. The ability of the probe to accurately measure wind direction, velocity magnitude and turbulence intensity in a range of flow conditions was verified against commercially available sensors. The feasibility of applying a general calibration to several probes and maintaining acceptable accuracy and repeatability was also investigated. The prototype system demonstrated acceptable accuracy for atmospheric wind measurements. Assessing the effectiveness of a generic calibration demonstrated initial positive results, however a larger sample size is required.
Déploiement continue des applications pervasives en milieux dynamiques (2014)

Driven by the emergence of new computing environments, dynamically evolving software systems makes it impossible for developers to deploy software with human-centric processes. Instead, there is an increasing need for automation tools that continuously deploy software into execution, in order to push updates or adapt existing software regarding contextual and business changes. Existing solutions fall short on providing fault-tolerant, reproducible deployments that would scale on heterogeneous environments. This thesis focuses especially on enabling continuous deployment solutions for dynamic execution platforms, such as would be found in Pervasive Computing environments. It adopts an approach based on a transactional, idempotent process for coordinating deployment actions. The thesis proposes a set of deployment tools, including a deployment manager capable of conducting deployments and continuously adapting applications according to the changes in the current state of the target platform. The implementation of these tools, Rondo, also allows developers and administrators to code application deployments thanks to a deployment descriptor DSL. Using the implementation of Rondo, the propositions of this thesis are validated in several industrial and academic projects by provisioning frameworks as well as on installing application and continuous reconfigurations.
Natural language processing Laboratory Plan: An essential for Persian language (2010)

Prevalent use of human language in computer systems and language oriented document processing, especially in the web, caused creating the need of designing mechanisms for developing natural language processing. In this paper, a survey in Natural Language Processing Laboratory has been done and a proposed framework for its development is suggested. Achieving this goal, the specifications, structures and activities of available Natural Language Processing Laboratories have been reviewed and valuable results are obtained. Afterward, a proposed framework is established. This framework introduces requirements of Laboratory in a structural way that providing solutions for it any clear plan in NLP Laboratories. Finally, according to National requirements of Iran and characteristics of Persian language, a Natural Language Processing Laboratory in discussed framework is designed. The activities of this laboratory includes basic tasks like creating linguistic resources (Corpora, Bilingual corpora, Lexicon, etc), test datasets, developing Natural Language Processing System's Evaluation Framework, development of basic tools (Parser, POS-tagger, etc), research tasks like defining areas for universities, and services such as application development, natural language processing system evaluation, and granting of the appropriate certificates.
Performance analysis of Viterbi decoder using channel state information in COFDM system (1998)

This paper relates to the application method of channel state information (CSI) to the Viterbi (maximum likelihood) decoder in the digital terrestrial television broadcasting system. The proposed Viterbi decoder uses the CSI derived from the pilots inserted in the transmitter of the COFDM (coded orthogonal frequency division multiplexing) system. The CSI is calculated by interpolation using the pilots in the receiver. The active real (I) and imaginary (Q) data after equalization are transferred to the branch metric calculation block that decides the euclidean distance for soft decision decoding and also the estimated CSI values are transferred to the same block. After calculating the euclidean distance for the soft decision decoding, the euclidean distance of the branch metric is multiplied by CSI. To do so, new branch metric values that consider each carrier state information are obtained. We simulated this method in Rayleigh fading defined in the ETSI standard. From the simulation, this method has better performance of about 0.15 dB to 0.7 dB and 2.2 dB to 2.9 dB in the Rayleigh channel than that of conventional soft decision Viterbi decoding with or without a bit interleaver where the constellation is QPSK, l6-QAM and 64-QAM.
Pathogenesis of Placentitis in the Goat Inoculated with <i>Brucella abortus</i> . I. Gross and Histologic Lesions (1986)

Pregnant goats were given Brucella abortus intravenously or in uterine arteries, and tissues from the uterus and placentae were examined at various post-inoculation intervals to study mechanisms of placental infection. Placentitis was present by 5 days post-inoculation and abortions occurred within 11 days. B. abortus was identified in placentae by light microscopy and immunoperoxidase techniques. B. abortus was first seen in erythrophagocytic trophoblasts of the placentome. Subsequently, high numbers of B. abortus were seen in periplacentomal chorioallantoic trophoblasts. Trophoblast necrosis, chorioallantoic ulceration, and large numbers of B. abortus in chorionic villi were present in later stages of infection. These results suggest that entry and replication of B. abortus in trophoblasts precede placentome and fetal infection and that trophoblasts are the source of B. abortus for these tissues. Experimental caprine brucellosis closely resembles bovine and ovine brucellosis and it provides a model to study the intracellular development of B. abortus in trophoblasts.
A compact and cost effective design for cell phone zoom lens (2007)

A compact zoom lens design for cell phone is presented. A three groups lens system with five lens element is designed for cell phone camera with 3M pixels and 2.5~3X optical zoom. The first lens is a negative lens with a concave surface facing the object so that, when used for a long focal length, the rear principle plane is moved forwards to shorten the total length of the lens. A positive lens group composed of three lens elements is arranged at the second lens group. By control the optical power of the second lens group, the distortion can be reduced and also shortens the moving distance of the second lens group while zooming. The fifth lens in the third lens group is a positive lens to control the incident angle entering the photosensitive element. It is used for focusing when the object distance has changed.
Convolutional neural network models for cancer type prediction based on gene expression (2019)

Background Precise prediction of cancer types is vital for cancer diagnosis and therapy. Important cancer marker genes can be inferred through predictive model. Several studies have attempted to build machine learning models for this task however none has taken into consideration the effects of tissue of origin that can potentially bias the identification of cancer markers. Results In this paper, we introduced several Convolutional Neural Network (CNN) models that take unstructured gene expression inputs to classify tumor and non-tumor samples into their designated cancer types or as normal. Based on different designs of gene embeddings and convolution schemes, we implemented three CNN models: 1D-CNN, 2D-Vanilla-CNN, and 2D-Hybrid-CNN. The models were trained and tested on combined 10,340 samples of 33 cancer types and 731 matched normal tissues of The Cancer Genome Atlas (TCGA). Our models achieved excellent prediction accuracies (93.9-95.0%) among 34 classes (33 cancers and normal). Furthermore, we interpreted one of the models, known as 1D-CNN model, with a guided saliency technique and identified a total of 2,090 cancer markers (108 per class). The concordance of differential expression of these markers between the cancer type they represent and others is confirmed. In breast cancer, for instance, our model identified well-known markers, such as GATA3 and ESR1. Finally, we extended the 1D-CNN model for prediction of breast cancer subtypes and achieved an average accuracy of 88.42% among 5 subtypes. The codes can be found at https://github.com/chenlabgccri/CancerTypePrediction.
An Investigation of Effect of Initial Income Distribution on Household Consumption in China (2014)

This paper examines the effect of the distribution of the national income on household consumption in China based on the data of 30 provinces between 1 993-2011. The result shows that the labor income has greater impact on household consumption than the profit income at the national level, but the inter-provincial heterogeneity is also indicated by regional differences. Profit income plays a decisive role in household consumption in the eastern area, while labor income functions mo re significant ly in the central region. At a result, constructive suggestions are made on the improvement of the residents’ revenues based on the fairness policy in order to protect employees’ working rights and opportunities with consideration of regional differences.
SCD: A scalable coherence directory with flexible sharer set encoding (2012)

Large-scale CMPs with hundreds of cores require a directory-based protocol to maintain cache coherence. However, previously proposed coherence directories are hard to scale beyond tens of cores, requiring either excessive area or energy, complex hierarchical protocols, or inexact representations of sharer sets that increase coherence traffic and degrade performance. We present SCD, a scalable coherence directory that relies on efficient highly-associative caches (such as zcaches) to implement a single-level directory that scales to thousands of cores, tracks sharer sets exactly, and incurs negligible directory-induced invalidations. SCD scales because, unlike conventional directories, it uses a variable number of directory tags to represent sharer sets: lines with one or few sharers use a single tag, while widely shared lines use additional tags, so tags remain small as the system scales up. We show that, thanks to the efficient highly-associative array it relies on, SCD can be fully characterized using analytical models, and can be sized to guarantee a negligible number of evictions independently of the workload. We evaluate SCD using simulations of a 1024-core CMP. For the same level of coverage, we find that SCD is 13× more area-efficient than full-map sparse directories, and 2× more area-efficient and faster than hierarchical directories, while requiring a simpler protocol. Furthermore, we show that SCD's analytical models are accurate in practice.
Bayesian Clustering of Categorical Time Series Using Finite Mixtures of Markov Chain Models (2009)

Two approaches for model-based clustering of categorical time series based on time- homogeneous first-order Markov chains are discussed. For Markov chain clustering the in- dividual transition probabilities are fixed to a group-specific transition matrix. In a new approach called Dirichlet multinomial clustering the rows of the individual transition matri- ces deviate from the group mean and follow a Dirichlet distribution with unknown group- specific hyperparameters. Estimation is carried out through Markov chain Monte Carlo. Various well-known clustering criteria are applied to select the number of groups. An appli- cation to a panel of Austrian wage mobility data leads to an interesting segmentation of the Austrian labor market.
Introduction (1989)

There is little doubt that the topic of family divisions and inequalities has emerged as a major theme within, helping to direct, the study of modern societies. The earlier publication, Family and Economy in Modern Society (Close and Collins, 1985), firmly draws on this theme and provides an immediate precursor to the present volume. The title of Family and Economy in Modern Society purposefully reflects what is often taken to be a major separation or divide which has developed within modern societies (advanced industrial, both capitalist and socialist): that between 'the public' and 'the private'. In other words, in conjunction with this divide, it is assumed that located at the hub of the private sphere of social life is 'the family' while at the hub of the public sphere is 'the economy'.1
Paclitaxel Antibody Conjugates and Trehalose for Preserving the Immunulogical Activity After Freeze-Drying (2004)

Antibodies and anticancer drug-antibody conjugates used in experimental cancer research or clinically must be freeze-dried for preserving the activity and storage at room temperature. This often results in some denaturation and loss of activity. We describe a recovery of the cytotoxic activity of a paclitaxel-mAb immunoconjugate after freeze-drying. The paclitaxel-antibody conjugate specific for ovarian cancer was tested both for its cytotoxicity in vitro and immunological activity after freeze drying in the presence of various preservatives. Results show that the inclusion of trehalose as a stabilizer at concentrations varying from the 0.25 and 0.40 M protected the antibody and saved the pharmacological activity. When PEG alone or with trehalose was used, the immunological and cytotoxic activities recovery were lower. Albumin was not protective. This study shows that the addition of trehalose for freeze drying labile drug is a promising method for storage of large quantities of the immunoconjugates for experimental and therapeutic use.
