A multiband robust planar antenna for wireless handheld devices

In this paper, a novel design of compact multi-band planar antenna is presented. Quarter-wavelength resonating slots are introduced on the radiating patch of a microstrip line fed monopole antenna. This arrangement provides reduced ground current effect. Moreover, ambient conditions like presence of nearby metallic structures, dielectric overlay, plastic casing, transceiver chips etc. are shown to have no significant effect on the antenna performance. This makes it a suitable candidate for applications in hand held devices. The input impedance of the antenna can be controlled by the slot position. A prototype tri-band antenna is designed for the 2.4/5.2/5.8 GHz wireless LAN frequency bands on a 0.813-mm thick RO4003 substrate with a dielectric constant of 3.55. The measured 10 dB return loss bandwidths cover and exceed the bandwidth requirements. The radiating patch has a compact dimension of 30×10 mm2.
Comparative central depressant actions of some 5-phenyl-5-alkyl barbituric acids.

1. Additional evidence, from studies of the comparative central actions of dialkyl, phenyl-alkyl and diphenyl barbituric acids, is presented to show that the mechanism which raises the convulsant threshold is different from the mechanism producing hypnosis as evidenced by ataxia and drowsiness. 2. Anticonvulsant activity of barbituric acid derivatives is intensified by the presence of one 5-phenyl group, diminished by the presence of a second 5-phenyl group, and maximal with the phenyl-butyl compound in the series of phenylalkyl barbituric acids. 3. Among the 5-phenyl-5-alkyl barbituric acids the widest range between anticonvulsant and hypnotic activities was found to be with 5-phenyl-5-butyl barbituric acid. 4. Of the ten dialkyl and phenyl-alkyl barbituric acids studied, 5-phenyl -5-butyl barbituric acid showed the most marked anticonvulsant activity at dose levels below the hypnotic dose range. 5. The hypnotic activities of the phenyl-alkyl barbituric acids are greatest with the compounds containing the smallest alkyl groups, and this type of central depressant activity decreases with increasing size of the alkyl group.
Twins and asthma

Editor—Strachan et al found an interesting difference between admissions to hospital for childhood asthma between twins and singletons.1 They conclude that there is reduced risk of asthma among twins. We found no significant difference in questionnaire based asthma diagnoses between singletons and twins aged 30-59 years among the Finnish twin cohort, but we did not give figures.2 The Finnish twin cohort is a population based sample of adult twin pairs of the same sex selected from the central population registry of Finland as pairs of individuals with the same birth date and sex, as well as the same surname and local community of birth. These selection criteria also captured some unrelated individuals. The unpublished figures are based on 12 024 twins and 2015 singletons. Age standardised prevalences of asthma were 2.1 (95% confidence interval 1.6 to 2.5) for male twins and 2.1 (1.1 to 3.0) for male singletons. For women, prevalences were 2.1 (1.7 to 2.5) and 2.5 (1.4 to 3.5) respectively. These findings are in accordance with studies among children and young adults from Finland and other Nordic countries.3–5 The reported occurrences of asthma in these twin studies correspond to those found in general populations. Although limitations arise because of interstudy differences (such as age range, definition of asthma, and study period) these studies support our findings among older adults. The reported differences in rates of admission to hospital may also be caused by different use of medical care among twins and singletons. Mothers of twins are on average older than mothers of singletons, and they usually also have other children. They therefore have more experience with children and their diseases. It is also probable that, when one twin has been in hospital for asthma, parents do not seek help for his or her twin sibling so easily because the situation is already familiar and medication may even be available at home.
Carrying robot system control based on neural network

The virtual torque control is a relative effective control law for the lower extremity carrying exoskeleton robot, which needs no direct measurements from the pilot or the human-machine interface, but it needs the exact mass properties and its PD controller is not applicable for the serious nonlinear system. To overcome these defaults, the virtual prototyping software ADAMS is introduced to model the exoskeleton and the model is also used to the neural network (NN) dynamic mathematics model study. At the same time, the NN is used to the dynamic feed-forward controller to compensate the human-machine interaction force. Theoretical analyse and simulation results test the feasibility and validity of this control method.
Detecting Congestion and Detour of Taxi Trip via GPS Data

With the continuous development of urbanization, taxi has been one of the main transports in daily trip. The current study of the taxi trip is more about the traffic situation and appropriate demand in this city. Our study by using DBSCAN (Density-Based Spatial Clustering of Applications with Noise), and find the abnormal driving items via taxi GPS data. Then we proposed a method to detect the congestion and detour that result in theses anomaly. We hope our work can provide useful references for the relevant departments to manage urban traffic.
Genome-Wide Identification and Expression Analysis of the Mitogen-Activated Protein Kinase Gene Family in Cassava

Mitogen-activated protein kinases (MAPKs) play central roles in plant developmental processes, hormone signaling transduction, and responses to abiotic stress. However, no data are currently available about the MAPK family in cassava, an important tropical crop. Herein, 21 MeMAPK genes were identified from cassava. Phylogenetic analysis indicated that MeMAPKs could be classified into four subfamilies. Gene structure analysis demonstrated that the number of introns in MeMAPK genes ranged from 1 to 10, suggesting large variation among cassava MAPK genes. Conserved motif analysis indicated that all MeMAPKs had typical protein kinase domains. Transcriptomic analysis suggested that MeMAPK genes showed differential expression patterns in distinct tissues and in response to drought stress between wild subspecies and cultivated varieties. Interaction networks and co-expression analyses revealed that crucial pathways controlled by MeMAPK networks may be involved in the differential response to drought stress in different accessions of cassava. Expression of nine selected MAPK genes showed that these genes could comprehensively respond to osmotic, salt, cold, oxidative stressors, and abscisic acid (ABA) signaling. These findings yield new insights into the transcriptional control of MAPK gene expression, provide an improved understanding of abiotic stress responses and signaling transduction in cassava, and lead to potential applications in the genetic improvement of cassava cultivars.
Dinucleotide microsatellite repeats are essential for the diagnosis of microsatellite instability in colorectal cancer in Asian patients.

AIM The molecular diagnosis of microsatellite instability (MSI) in colorectal cancer (CRC) is based on the analysis of five microsatellite markers. Among them, the two mononucleotide microsatellite repeats are considered more informative for this analysis than the three dinucleotide ones. The aim of this study is to establish the most relevant markers for MSI analysis in colorectal cancers from Asian patients. METHODS The MSI analysis of 143 CRC cases in a routine molecular diagnostic laboratory was reviewed. Analysis by fluorescence-based PCR of the five recommended microsatellites was performed, followed by data interpretation according to internationally accepted guidelines. The results were analyzed to address (1) the rate of success in the analysis of histopathological samples not specifically prepared for molecular analysis; (2) the relative importance of individual markers in the diagnosis of high-MSI (H-MSI). RESULTS MSI analysis was unsuccessful in 34 cases (24%), but for tissues archived in recent years the unsuccessful rate was 5%. We found the D2S123 marker the most vulnerable to inadequate tissue preservation, failing to amplify in 58 instances. Approximately 30% (32/109) of the cases were H-MSI, while 7/109 (6%) were low-MSI. A detailed analysis of the H-MSI cases revealed that the dinucleotide repeats (and D5S346 in particular) were more relevant than the mononucleotide repeats in assigning the correct MSI status. CONCLUSION The analysis of dinucleotide repeats is essential for the establishment of MSI status in Asian CRC patients.
The use of optimization methods-and thermodynamic implications-in mineraology

This research has been bound together by one common theme: optimization. Chapters one and two are examples of traditional crystal structure refinements. Chapter three explains the site assign problem and documents a new approach to the problem. Chapter four extends the method to high temperaturese; chapter five extracts the thermodynamic information found in the site occupancies. The appendix is a user's manual for OCCQP. In chapter one the structure and formula of brackebuschite was redefined. Also, the crystal chemistry of the d4 Mn3+ ion in oxygen-based minerals is reviewed. Chapter two presents the refinement of redledgeite. It and its synthetic equivalent are important as a solid-state repository for toxic heavy-metal waste. With chapter three, the traditional methods of determining site occupancies in minerals come in to question. The approach is based on crystal-structure data and chemical analyses of the compound, without making prior assumptions. This method provides the flexibility to evaluate trade-offs inherent in assigning occupancies on the basis of a single criterion. Multiple criteria may be used and their relative importance adjusted interactively. The optimizations yield excellent results. Chapter four builds upon the foundation established in chapter three. This chapter is a reexamination of the cation partitioning of the same spinel used in chapter three. This method led to strikingly different results from the authors of the original study, supporting the general view that spinel undergoes a lambda transition at ~1000K. Chapter five extends the thermodynamic formulations for spinel. Most thermodynamic studies of spinels have focused on simple end-member compositions, meaning only two cations—at most—are distributed among the octahedral and tetrahedral sites. This chapter considers a 2-3 spinel having three cation species and vacancies. The standard thermodynamic technique is to consider migration of cations between octahedral and tetrahedral positions as reactions. The stability coefficient D K gives the changes in Gibbs free energy of distribution, and statistical mechanics yields the entropy of distribution.

Smarter Phone based Live QoE Measurement

Quality of Experience (QoE) is the users' most direct assessment of the network operator's service. How to accurately and efficiently collect QoE data from a point near the user is always a technical challenge to the operators. The way QoE related information submitted to the management system is important because the volume of the data may be excessive enough to interfere with the ordinary chargeable services. After the comparison of two current QoE collection methods, this paper reviews recent technical improvements in QoE measurement area and provides an analysis of smart phone capability. Finally the Smarter Phone based Live QoE Measurement method is proposed. The advantage of this method is to bring sophisticated and complex live QoE measurement process onto the powerful smart phones hence reduce the data collection and transmission load of the network while provide a live and accurate QoE measurement.
General Versus Specific Sentences: Automatic Identification and Application to Analysis of News Summaries

In this paper, we introduce the task of identifying general and specific sentences in news articles. Instead of embarking on a new annotation effort to obtain data for the task, we explore the possibility of leveraging existing large corpora annotated with discourse information to train a classifier. We introduce several classes of features that capture lexical and syntactic information, as well as word specificity and polarity. We then use the classifier to analyze the distribution of general and specific sentences in human and machine summaries of news articles. We discover that while all types of summaries tend to be more specific than the original documents, human abstracts contain a more balanced mix of general and specific sentences but automatic summaries are overwhelmingly specific. Our findings give strong evidence for the need for a new task in (abstractive) summarization: identification and generation of general sentences.

Management of chronic constipation in adults

Chronic constipation (CC) is an extremely common condition with an estimated prevalence of up to 24%. Most patients with CC should be treated in primary care. Changes in lifestyle, including increased intake of dietary fibre, fluid, and exercise, should be attempted in most patients. Osmotic or stimulant laxatives are indicated if there are insufficient effects of lifestyle changes. Prokinetics and secretagogues should be restricted to those not responding to basic treatment. Anorectal physiology tests and assessment of colorectal transit time are indicated if medical treatment fails or if symptoms indicate severely obstructed defecation. If symptoms indicate an underlying structural disorder, barium or magnetic resonance evacuation proctography is indicated. Biofeedback therapy is effective in patients with dyssynergic defecation. In patients with other evacuation disorders, rectally administered laxatives or transanal irrigation should be attempted. Surgery is restricted to the minority of CC patients with very severe symptoms not responding to conservative treatment.
On the Width of Semi-Algebraic Proofs and Algorithms

In this paper we initiate the study of width in semi-algebraic proof systems and various cut-based procedures in integer programming. We focus on two important systems: Gomory-Chvatal cutting planes and Lovasz-Schrijver lift-and-project procedures. We develop general methods for proving width lower bounds and apply them to random k-CNFs and several popular combinatorial principles like the perfect matching principle and Tseitin tautologies. We also show how to apply our methods to various combinatorial optimization problems. We establish an “ultimate” trade-off between width and rank, that is give an example in which small width proofs are possible but require exponentially many rounds to perform them.
Cutting bubbles using wire-mesh structures : direct numerical simulations

Bubble column reactors suffer from bubble coalescence resulting in a decreased mass transfer efficiency. In order to increase the mass transfer rate in bubble column reactors, a novel reactor is proposed, the Micro-Structured Bubble Column (MSBC). is novel reactor makes use of a wire-mesh serving the purpose of cuing bubbles into smaller bubbles. is increases the specific bubble surface area as well as the mass transfer coefficient, due to the enhanced surface dynamics. e first step is understanding the fluid-structure interaction in the limiting case of single-phase flow past crossing cylinders not reported in literature so far. To this end Direct Numerical Simulations (DNS) are performed, where the presence of the wire-mesh consisting of intersecting cylinders is accounted for by using an Immersed Boundary Method (IBM). e IBM is verified with existing literature data for flow past a single cylinder. Finally an extensive set of simulations has been conducted for intersecting cylinders varying in cylinder diameter and Reynolds numbers. From these simulations a new drag relation is derived describing the drag as a function of the Reynolds number and the pitch to cylinder diameter, p/D, ratio. *is chapter is based on: Segers, Kuipers, and Deen (2013)
The associations between leukocyte, erythrocyte or platelet, and metabolic syndrome in different genders of Chinese

AbstractLeukocyte, erythrocyte or platelet and metabolic syndrome (MS) are closely correlated, and there exist gender differences. We aimed to explore the associations between the hematological parameters and MS in different genders of Chinese. This cross-sectional study included 32,900 participants (20,733 males, 12,167 females) who were enrolled in a health examination. Clinical data including anthropometric measurements and serum parameters were collected. The associations between hematological parameters and MS of both genders were analyzed separately. Odds ratio (OR) of MS was calculated by binary logistic regression models. All hematological parameters were related to MS. With leukocyte and erythrocyte counts rising, the risks of developing MS increased in both genders, which was more obvious in women. For instance, in model 3, the ORs of MS in leukocyte quartiles in females were from 1.333 to 2.045 (P < 0.01), while in males, from 1.238 to 1.675 (P < 0.01). Platelet seemed as a protective factor in males. Model 1 and model 3 in quartile 2 demonstrated ORs of 0.922 (P < 0.05) and 0.912 (P < 0.05). However, platelet acted as risk factor in female. For instance, the ORs were 1.253 (P < 0.01), 1.461 (P < 0.01), and 1.322 (P < 0.01) in platelet quartile 4 of all 3 models in female. Gender has influences on the associations between leukocyte, erythrocyte or platelet, and MS. In both genders, higher levels of leukocyte and erythrocyte increased risks of MS. For men, platelet was a protective factor, but for women, platelet seemed as a risk factor.
Estimating the spectrum of a density matrix with LOCC

The problem of estimating the spectrum of a density matrix is considered. Other problems, such as bipartite pure state entanglement, can be reduced to spectrum estimation. A local operations and classical communication (LOCC) measurement strategy is shown which is asymptotically optimal. This means that, for a very large number of copies, it becomes unnecessary to perform collective measurements which should be more difficult to implement in practice.
Freeze-Thaw Durability of Portland Cement Concrete Subjected to Aircraft Deicer

Influence of glycol, which is the main composition of the most frequently used aircraft dicer, on the freeze-thaw durability of Portland cement concrete were investigated. Freeze-thaw durability of Portland cement concrete was tested by accelerated freeze-thaw test. Four kinds of solutions, namely tap water, 3.5% NaCl solution, glycol solutions and a LBR-A type commercial aircraft deicer were employed to be the freezing-thawing mediums. Results show that freeze-thaw durability of concrete exposed to glycol solutions is closely related to the solution concentrations. Failure of concretes exposed to 3.5% glycol solution is similar to that of those exposed 3.5% NaCl solution, which are attributed to serious surface scaling. While damage of concrete exposed to 12.5% and 25% glycol solutions are postponed, and the durability of concrete are increased. Compared with glycol solution, the commercial aircraft deicer demonstrated much more negative effect to concrete freeze-thaw durability, and the degree even exceeds 3.5% NaCl solution. Consequently, the commercial aircraft deicer is not a kind of environmental friendly deicer as usually considered.
Transfer Learning with Markov Logic Networks

We propose a new algorithm for transfer learning of Markov Logic Network (MLN) structure. An important aspect of our approach is that it first diagnoses the provided source MLN and then focuses on re-learning only the incorrect portions. Experiments in a pair of synthetic domains demonstrate that this strategy significantly decreases the search space and speeds up learning while maintaining a level of accuracy comparable to that of the current best algorithm.
Hand Gesture Recognition Using Color and Depth Images Enhanced with Hand Angular Pose Data *

— In this paper we propose a hand gesture recognition system that relies on color and depth images, and on a small pose sensor on the human palm. Monocular and stereo vision systems have been used for human pose and gesture recognition, but with limited scope due to limitations on texture, illumination, etc. New RGB-Depth sensors, that reply on projected light such as the Microsoft Kinect, have overcome many of those limitations. However, the point clouds for hand gestures are still in many cases noisy and partially occluded, and hand gesture recognition is not trivial. Hand gesture recognition is much more complex than full body motion, since we can have the hands in any orientation and can not assume a standing body on a ground plane. In this work we propose to add a tiny pose sensor to the human palm, with a minute accelerometer and magnetometer that combined provide 3D angular pose, to reduce the search space and have a robust and computationally light recognition method. Starting with the full depth image point cloud, segmentation can be performed by taking into account the relative depth and hand orientation, as well as skin color. Identification is then performed by matching 3D voxel occupancy against a gesture template database. Preliminary results are presented for the recognition of Portuguese Sign Language alphabet, showing the validity of the approach.
On the Class of Predicates Decidable by Two-Way Multitape Finite Automata

The problem of deciding predicates concerned with m-tuples of words by means of 2-way multitape finite automata is considered. In general, more than m tapes are used to decide a predicate concerned with m-tuples of words. In such a way, a necessary and sufficient condition for a predicate to be decidable by a 2-way multitape finite automaton is obtained. The relation between the ability of Turing machines and that of 2-way multitape finite automata is also discussed.
Distortion Analysis Using Volterra Series and Linearization Technique of Nano-Scale Bulk-Driven CMOS RF Amplifier

The distortion analysis of nano-scale bulk-driven (BD) CMOS RF amplifier is presented based on Volterra series. The first three-order Volterra kernels are computed; and the closed-form expressions of the second-order and third-order harmonic distortion (HD) are derived. These expressions give good accuracy comparing with the simulation results, and can provide insight into the nonlinearity of nano-scale BD amplifier. These expressions unveil and demonstrate that the nano-scale BD MOSFET has distinct nonlinear characteristics. Also, distortion-aware design guidelines for nano-meter CMOS BD amplifier are provided. A modified second-order intermodulation (IM2) injection technique is presented to suppress the third-order intermodulation (IM3) product. This modified technique which consumes only 64 μA current employs phase adjustment of the low-frequency IM2; and up to 20 dB IM3 reduction is achieved over 1 MHz-20 MHz two-tone spacing range without gain reduction or noise penalty.
