Study of SAW Based on a Micro Force Sensor in Wireless Sensor Network

Wireless sensor network (WSN) technology has increasingly assumed an active role in detection, identification, location, and tracking applications after more than ten years of development. However, its application still suffers from technology bottlenecks, which must be solved and perfected to eliminate the key problems of the technology. This article investigates WSN acquisition nodes and analyzes the relationship between the frequency and actual pressure values of sensor nodes. The sensitive mechanism of the surface acoustic wave (SAW) based on a micro force sensor is researched, and the principle of least squares method is used to establish a transformation model of frequency and pressure for the SAW sensor. According to the model, polyfit function and matrix calculation are selected to solve and calculate the estimate of the polynomial coefficients, which simulate the data acquisition of WSN nodes and draw a polynomial curve fitting. The actual SAW sensor is tested to demonstrate the reasonableness of the device stability in WSNs.
Duration of hypertension is associated with cognitive function: a cross‐sectional study in Chinese adults

Background Hypertension (HTN) is a very prevalent public health problem and as the population ages, cognitive impairment (CI) is also going to be a public health burden. However, the relationship between hypertension duration and cognitive function declination worldwide is still unknown. The aim of the study was to investigate the effects of HTN duration on CI in Chinese population. Methods At baseline, 1 386 HTN patients and 293 normotensive (NT) people were enrolled. The HTN patients were further divided into four subgroups (duration of HTN <6 years, 6–10 years, 11–20 years, and >20 years) according to the HTN duration and were screened for cognitive function with neuropsychological tests including mini‐mental‐stateexamination (MMSE) and clock‐drawing‐test (CDT) in comparison with the NT group. Results More HTN patients had CI (45.3%) than NT subjects (30.4%), and increased with HTN duration (P <0.000 1). Compared with the scores of MMSE and CDT in the NT group, the declines were higher in the HTN patients (P <0.000 1), and in the four HTN subgroups, both MMSE and CDT scores fall when the HTN duration increased (P <0.05). Furthermore, in the HTN population without CI, the trend in alteration of CI was relatively mild but still existed (P <0.05). Conclusion People with HTN are more likely to have CI and the possibility and aggravation increases the prolongation of HTN duration, both in amnesic and nonamnesic function.
Attachment security in young foster children: continuity from 2 to 3 years of age

The present study investigated attachment patterns among 60 foster children (FC) and 42 comparison children (CC) at 2 years (T1) and again at 3 years (T2) of age, as well as stability from T1 to T2. Descriptive analyses, including cross-tabulation, were used to present attachment patterns, group differences and stability from T1 to T2. Most FC were securely attached at T1, and no group differences were identified; neither the FC nor CC differed from typical children in their attachment patterns. Furthermore, the majority of children in both groups received the same classification at both time points. Among FC who were securely attached at T1, a majority remained so at T2, while among those classified as disorganized at T1, significantly less remained so at T2. The study suggests that young FC have the possibility to form enduring secure attachments when placed in stable and well-functioning foster homes.
Root Cause Analysis and Health Informatics

Root Cause Analysis (RCA) is the most widely used system analysis tool for investigating safety related incidents in healthcare. This contribution reviews RCA techniques, using a Health Informatics example, and discusses barriers to their successful uptake by healthcare organisations. It is concluded that a critical assessment to examine the uptake and evaluate the success of RCA, and other safety related techniques, within healthcare is long overdue.
Sequence, secondary structure and phylogenetic analyses of the ribosomal internal transcribed spacer 2 (ITS2) in the Timarcha leaf beetles (Coleoptera: Chrysomelidae)

Internal transcribed spacer 2 (ITS2) sequences of the nuclear rDNA in forty‐seven specimens (thirty‐four species) of the leaf beetle genus Timarcha have been studied. Timarcha ITS2 (523 bp on average) share some sequence features with other Chrysomeloidea relatives (Chrysolina, Diabrotica and Bruchus) but have no clear similarity with any other arthropod ITS2 sequences. Interspecific divergences are in the range 0.002–0.166, and 0.124–0.206 in the comparisons between subgenera. No evidence of intragenomic divergent ITS2 sequences has been found. Secondary structures are concordant with the four‐domain model proposed for vertebrates and yeast, but differs from those proposed for dipterans. Phylogenetic analysis of the ITS2 data confirms the results of a previous study based on mitochondrial sequences, as the basality of the Metallotimarcha subgenus and the absence of phylogenetic support for the Timarchostoma subgenus.
Detection of similarity in music files using signal level analysis

In today's age of digital media, the collection of music files available to the general public is extremely diverse. As with any such set of data, efforts must be made to classify and categorize these files in order to facilitate easy access and searching. Songs can be classified based on attributes available in the music file's metadata such as artist, album, year of release, length, etc. However, if the similarity between two songs is to be determined, a simple comparison of metadata is not only unsatisfactory, the metadata itself might not be available. Therefore, a method of comparison independent of the availability of metadata is required. In this work, a comparison method has been proposed involving the use of musical parameters such as tempo, key and signal envelope, which are extracted from the music file through signal level analysis. Genre is also computed using a support vector machine (SVM) classifier and used to estimate the similarity between two songs.
p53-dependent repression of polo-like kinase-1 (PLK1)

PLK1 is a critical mediator of G2/M cell cycle transition that is inactivated and depleted as part of the DNA damage-induced G2/M checkpoint. Here we show that down-regulation of PLK1 expression occurs through a transcriptional repression mechanism and that p53 is both necessary and sufficient to mediate this effect. Repression of PLK1 by p53 occurs independently of p21 and of arrest at G1/S where PLK1 levels are normally repressed in a cell cycle-dependent manner through a CDE/CHR element. Chromatin immunoprecipitation analysis indicates that p53 is present on the PLK1 promoter at two distinct sites termed p53RE1 and p53RE2. Recruitment of p53 to p53RE2, but not to p53RE1, is stimulated in response to DNA damage and/or p53 activation and is coincident with repression-associated changes in the chromatin. Down-regulation of PLK1 expression by p53 is relieved by the histone deacetylase inhibitor, trichostatin A, and involves recruitment of histone deacetylase to the vicinity of p53RE2, further supporting a transcriptional repression mechanism. Additionally, wild type, but not mutant, p53 represses expression of the PLK1 promoter when fused upstream of a reporter gene. Silencing of PLK1 expression by RNAi interferes with cell cycle progression consistent with a role in the p53-mediated checkpoint. These data establish PLK1 as a direct transcriptional target of p53, independently of p21, that is required for efficient G2/M arrest.
Scene text recognition by learning co-occurrence of strokes based on spatiality embedded dictionary

Text information contained in scene images is very helpful for high-level image understanding. In this study, the authors propose to learn co-occurrence of local strokes for scene text recognition by using a spatiality embedded dictionary (SED). Unlike spatial pyramid partitioning images into grids to incorporate spatial information, the authors SED associates every codeword with a particular response region and introduces more precise spatial information for robust character recognition. After localised soft coding and max pooling of the first layer, a sparse dictionary is learned to model co-occurrence of several local strokes, which further improves classification performance. Experimental results on two scene character recognition datasets ICDAR2003 and CHARS74 K demonstrate that their character recognition method outperforms state-of-the-art methods. Besides, competitive word recognition results are also reported for four benchmark word recognition datasets ICDAR2003, ICDAR2011, ICDAR2013 and street view text when combining their character recognition method with a conditional random field language model.
A Comparison of Reinforcement Learning Techniques for Fuzzy Cloud Auto-Scaling

A goal of cloud service management is to design self-adaptable auto-scaler to react to workload fluctuations and changing the resources assigned. The key problem is how and when to add/remove resources in order to meet agreed service-level agreements. Reducing application cost and guaranteeing service-level agreements (SLAs) are two critical factors of dynamic controller design. In this paper, we compare two dynamic learning strategies based on a fuzzy logic system, which learns and modifies fuzzy scaling rules at runtime. A self-adaptive fuzzy logic controller is combined with two reinforcement learning (RL) approaches: (i) Fuzzy SARSA learning FSL and (ii) Fuzzy Q-learning FQL. As an off-policy approach, Q-learning learns independent of the policy currently followed, whereas SARSA as an on-policy always incorporates the actual agent's behavior and leads to faster learning. Both approaches are implemented and compared in their advantages and disadvantages, here in the OpenStack cloud platform. We demonstrate that both auto-scaling approaches can handle various load traffic situations, sudden and periodic, and delivering resources on demand while reducing operating costs and preventing SLA violations. The experimental results demonstrate that FSL and FQL have acceptable performance in terms of adjusted number of virtual machine targeted to optimize SLA compliance and response time.
Harmonic analysis on semisimple Lie groups

Then tr 4̂ is actually independent of the choice of this base. Let VT denote the set of a l l /G^ i (G) such that ir(f) is of the trace class. Then Vr is a linear subspace of Li(G). Put 0 . ( / ) = tr *•(ƒ) ( f £ F T ) . Then ®T is a linear function on VT which we may call the character of 7T. Of course this concept would be useful only when the space V* is fairly large. Let 8(G) denote the set of all equivalence classes of irreducible unitary representations of G. It is easy to see that for any representation x, VT and ©^ depend only on the class co of 7r. Hence we may de-
SEROLOGIC EVIDENCE OF INFECTION WITH GRANULOCYTIC EHRLICHIAE IN BLACK BEARS IN PENNSYLVANIA

Serum samples from 381 black bears (Ursus americanus) killed in Pennsylvania (USA) on 24 November 1997 were analyzed for antibodies reactive to the agent of human granulocytic ehrlichiosis (HGE; Ehrlichiasp.) by indirect immunofluorescence assay. Antibody reactivity to HGE antigen was detected in 21% (81/381) of the samples collected. Reactive samples were reported from 56% (14/25) of the counties where bear samples were collected. Endpoint antibody titer ranged from 1:8 to 1:16, 192, with a geometric mean titer of 1:582. There was no significant difference in antibody prevalence between male and female bears (P < 0.01). However, adult bears were significantly more likely to have reactive antibodies than juvenile bears (P < 0.01). Attempts to amplify and detect granulocytic ehrlichial DNA from corresponding bear blood clots (n = 181) through nested polymerase chain reaction assays were unsuccessful. Further studies are needed for identification of the pathogen-responsible for induction of HGE-reactive. This is the first description of antibodies reactive to the HGE agent in black bears and suggests these mammals are infected with the agent of HGE or an antigenically related ehrlichial species.
DISSEMINATED TUBERCULOSIS PRESENTING AS HEMOPHAGOCYTIC LYMPHOHISTIOCYTOSIS

ABSTRACT Hemophagocytic lymphohistiocytosis (HLH) is an immune dysregulation syndrome which is characterized by widespread but ineffective activation of immune system of our body. This activation leads to release of a large pool of cytokines from the activated lymphocytes and macrophages. This hypercytokinemia leads to the development of characteristic features of HLH such as fever, cytopenias, hepatosplenomegaly, raised serum ferritin level, hemophagocytosis in marrow/spleen/lymph nodes, low fibrinogen and or hypertriglyceridemia, low natural killer cell activity, and high-soluble CD25 [1]. Five out of the above eight features are required for the diagnosis. There are 2 variants of HLH, primary HLH; where the defect in the immune system is hereditary and secondary HLH; where it is caused by other secondary diseases such as infections, hematological malignancies, autoimmune and auto-inflammatory diseases. In this article, we have reported a case of HLH, which was secondary to disseminated tuberculosis. There are only few case reports of HLH secondary to disseminated tuberculosis. Mortality may be as high as 50%. Although tuberculosis has various manifestations, our patient presented with fever, skin rash, cytopenias, splenomegaly, and very high ferritin. Marrow examination showed epithelioid granuloma, hemophagocytosis, and positive Ziehl–Neelsen staining. At present, no definite treatment guidelines have been formulated because of multiple drug interactions and toxicities. We treated our patient with non-hepatotoxic anti-tubercular drugs and steroids, followed by addition of isoniazid, rifampicin, and pyrazinamide on improvement of hepatic profile. Thus, high index of clinical suspicion, prompt diagnosis, and early management may reduce the mortality in this devastating disease. Moreover, this is more common in immunocompromised patients, but here, we have diagnosed this case in an immunocompetent man. Keywords: Erythematous rash, Fever, Disseminated tuberculosis.
Active clamp boost converter with switched capacitor and coupled inductor

A high step-up converter with a coupled inductor and a switched capacitor is proposed in this paper. By using the coupled inductor, the voltage gain of the converter is extended and the voltage stress of the main switch is decreased to reduce the conduction losses. Moreover, the reverse-recovery problem of the output diode is alleviated by the leakage inductance. By using the switched capacitor, the resonance between the leakage inductance and the stray capacitor of the output diode is eliminated. Additionally, an active clamp circuit is induced here to depress the voltage spikes of the main switch and to recycle the energy stored in the leakage inductance. Both the main switch and the clamp switch work with zero-voltage-switching (ZVS) performance, which reduces the switching losses significantly. At last, a 500W prototype is built to verify the analysis. The highest efficiency of the prototype is 96% and the efficiency is over 93% in a wide load range.
Rapid Production Changes through the Coordination of Factory Layout Models and Activities

Changing the design of a factory in practice involves the change of a number of parallel and interdependent systems such as the machining resources and robot cells, the supply systems for electricity, water, air, heat and cooling, pneumatics and hydraulics, the systems for chip and waste handling, process fluid, communication networks, sprinkler systems, as well as the building construction. Thus the coordination of information and models, as well as of the design work activities, is of utmost importance to achieve a fast and flexible development process. This paper presents the results from a research project focusing on computer aided work processes and the communication of models between various stake holders in layout design. The primary objective was to provide methods for a coordinated factory development process with a facilitated information exchange and reuse of knowledge and models. Results concerning required layout and PLM (Product Lifecycle Management) functionalities, as well as modelling and communication principles, tested in an industrial case, are presented.
Effect of eplerenone, enalapril and their combination treatment on diabetic nephropathy in type II diabetic rats.

BACKGROUND Recent data suggest that aldosterone antagonists have beneficial effects on diabetic nephropathy. In this study, we investigated the dose-dependent effect of eplerenone and a combined treatment with eplerenone and enalapril compared with each drug alone on renal function in type II diabetic rats. To further explore the molecular mechanism of action of combination therapy, we also performed in vitro study. METHODS The animals were divided into six groups as follows: normal control Long-Evans Tokushima Otsuka (LETO) rats, Otsuka Long-Evans Tokushima Fatty (OLETF) rats, OLETF rats treated with low dose of eplerenone (50 mg/kg/day), OLETF rats treated with high dose of eplerenone (200 mg/kg/day), OLETF rats treated with enalapril (10 mg/kg/day) and OLETF rats treated with a combination of both drugs (eplerenone 200 mg/kg/day and enalapril 10 mg/kg/day) for 6 months. RESULTS Treatment of OLETF rats had no significant effect on body weight, kidney weight and blood glucose levels. However, urinary albumin excretion, glomerular filtration rate and glomerulosclerosis were significantly improved in the enalapril group and improvement was observed in a dose-dependent manner in the eplerenone groups; the most dramatic decreases were observed in the combination group. In accordance with these findings, renal expressions of TGF-beta1, type IV collagen and PAI-1 were also markedly decreased in the treatment groups, with the combined treatment providing the most significant level of improvement. In cultured mesangial cells, combined treatment resulted in an additive decrease in TGF-beta1, PAI-1 and collagen gene expressions and protein production induced by high glucose and aldosterone stimulation. CONCLUSIONS Aldosterone receptor antagonism provided additional benefits beyond blockade of the renin-angiotensin system in type II diabetic nephropathy.

A structured test re-use methodology for core-based system chips

This paper describes a structured test re-use methodology and infrastructure for core-based system chips. The methodology is based on the use of a structured test bus framework that provides access to virtual components in a system chip allowing the test methodologies and test vectors for these components to be re-used. It addresses the test access, isolation, interconnect and shadow logic test problems without requiring modifications to the components, even for cores with more ports than chip pins. The test area overhead required, including test bus routing, to implement this methodology can be less than 1%.
The Picker MagnaScanner with constant dot spacing colour print-out and background cut-off.

Investigations of the value of a constant dot spacing for the colour print-out of a Picker MagnaScanner III have been made using an astable multivibrator primarily designed to calibrate the colour print-out and photo-scan. With an arrangement similar to that of McCready and Beechey (1967), pulses were passed directly into the colour print chassis through plug 2806-D, in place of the signal from the pulse chassis. Results were encouraging and a circuit has now been built which takes fuller advantage of the facilities of the scanner circuitry.
A 3-ps dead-zone double-edge-checking phase-frequency-detector with 4.78 GHz operating frequencies

This work proposes a double-edge-checking phase frequency detector (dec-PFD), designed in 0.35-/spl mu/m CMOS process with 3-V supply voltage. Consisting of four-states without feedback paths, the dec-PFD can avoid U/sub p/ and D/sub OWN/ signals from rising to high at the same time and thus solve current mismatch problem with 3-ps dead-zone in the phase detection. The maximum operating frequency of the PFD is 4.78 GHz. Simulated results are presented to demonstrate the capability of phase detection of the circuit.
Gender and Role Differences in Couples’ Communication During Cancer Survivorship

Background: Individuals with cancer and their partners often experience communication difficulties. However, questions still remain regarding the influence of gender and role in cancer survivor-partner communication within couples. Objective: The current study intended to examine the communication patterns in breast, colorectal, and prostate cancer survivor-partner couples during cancer survivorship and whether gender and role differences in couples communication exist. Methods: The dominant-less dominant method of sequential mixed design was used. Ten couples who were recruited from the University Hospital registry in Cleveland, Ohio, participated in both mail surveys and individual interviews. Family and cancer-related communication was assessed in the quantitative phase. Results: Both male survivors and partners demonstrated better family communication scores compared with their female counterparts, whereas there were no gender differences in the cancer-related communication scores. In the qualitative phase, 3 major themes were identified: (1) selective sharing of cancer-related issues, (2) initiation of cancer-related communication, and (3) emotional reaction in communication. The patterns associated with these themes differed between the male survivor-female partner and female survivor-male partner couples. Conclusions: This study provides new knowledge about family and cancer-related communication. Our findings highlight the importance of understanding different perspectives in the quality of communication by gender and role. Implications for Practice: Exploring couples’ communication patterns by gender and role stimulates the research and the development of effective consumer-centered communication interventions. The findings provide assessment tools to inform dyadic communication patterns for clinical and scientific purposes.
