Automated System Monitoring and Notification with Swatch

This paper describes an approach to monitoring events on a large number of servers and workstations. While modern UNIX systems are capable of logging a variety of information concerning the health and status of their hardware and operating system software, they are generally not configured to do so. Even when this information is logged, it is often hidden in places that are either not monitored regularly or are susceptible to deletion or modification by a successful intruder. Also, a system administrator must often monitor several, perhaps dozens, of systems. To address these problems, our approach begins with the modification of certain system programs to enhance their logging capabilities. In addition, our approach calls for the logging facilities on each of these systems to be configured in such a way as to send a copy of the critical system and security related information to a dependable, secure, central logging host system. As one might expect, this central log can see a megabyte or more of data in a single day. To keep a system administrator from being overwhelmed by a large quantity of data we have developed an easily configurable log file filter/monitor, called swatch. Swatch monitors log files and acts to filter out unwanted data and take one or more user specified actions (ring bell, send mail, execute a script, etc.) based upon patterns in the log.
Designing PID Controller For DC Motor By Means Of Chaos Enhanced PSO Algorithm

In this paper it is investigated the possibility of using chaos enhanced PSO algorithm in the task of PID controller design. The experimental DC motor system is used as the problem design and four different criterions are used to measure the quality of the regulation. Four different chaotic systems are used as pseudo-random number generators for the PSO algorithm and promising results of this method are presented and discussed.
Postnatal Deletion of Wnt7a Inhibits Uterine Gland Morphogenesis and Compromises Adult Fertility in Mice1

The success of postnatal uterine morphogenesis dictates, in part, the embryotrophic potential and functional capacity of the adult uterus. The definitive role of Wnt7a in postnatal uterine development and adult function requires a conditional knockout, because global deletion disrupts müllerian duct patterning, specification, and cell fate in the fetus. The Wnt7a-null uterus appears to be posteriorized because of developmental defects in the embryo, as evidenced by the stratified luminal epithelium that is normally found in the vagina and the presence of short and uncoiled oviducts. To understand the biological role of WNT7A after birth and allow tissue-selective deletion of Wnt7a, we generated loxP-flanked exon 2 mice and conditionally deleted Wnt7a after birth in the uterus by crossing them with PgrCre mice. Morphological examination revealed no obvious differences in the vagina, cervix, oviduct, or ovary. The uteri of Wnt7a mutant mice contained no endometrial glands, whereas all other uterine cell types appeared to be normal. Postnatal differentiation of endometrial glands was observed in control mice, but not in mutant mice, between Postnatal Days 3 and 12. Expression of morphoregulatory genes, particularly Foxa2, Hoxa10, Hoxa11, Msx1, and Wnt16, was disrupted in the Wnt7a mutant uteri. Conditional Wnt7a mutant mice were not fertile. Although embryos were present in uteri of mutant mice on Day 3.5 of pregnancy, blastocyst implantation was not observed on Day 5.5. Furthermore, expression of several genes (Foxa2, Lif, Msx1, and Wnt16) was reduced or absent in adult Wnt7a-deleted uteri on Day 3.5 postmating. These results indicate that WNT7A plays a critical role in postnatal uterine gland morphogenesis and function, which are important for blastocyst implantation and fertility in the adult uterus.
Reinvestigation of the structure of acyl galactosyl diglyceride from spinach leaves.

Abstract : Shown by nuclear magnetic resonance spectroscopy and by synthesis is that the acyl galactosyl diglyceride from spinach leaves is 1',2'-di-O-acyl-3'-O-(6-O-acyl-beta-D-galactopyranosyl)-sn-glycerol and not a mixture of isomers as reported previously. (Author)
Recognizing facial images using ICA, LPP, MACE Gabor Filters, Score Level Fusion Techniques

We have developed and analyzed Independent Component Analysis (ICA), Locality Preserving Projections (LPP), Minimum Average Correlation Energy (MACE) Gabor Filters, Score Level Fusion Techniques (SLFT) for Face Recognition in the presence of various noises and blurring effects. ICA considers statistical characteristics in second order or higher order. LPP is used to generate an unsupervised neighborhood graph on training data, and then finds an optimal locality preserving projection matrix under certain criterion. MACE Gabor filter synthesizes a filter using a set of training images that would produce correlation output that minimizes correlation values at locations other than the origin and the value at the origin is constrained to a specific peak value. ICA, LPP, MACE Gabor Filter, SLFT are the 4 systems developed which were trained in the absence of noise, blurring effect but tested by imposing different levels of noises and blurring effects. To compare the performances six public face databases: IITK, ATT, JAFEE, CALTECH, GRIMACE, and SHEFFIELD are considered.
The coordinated radio and infrared survey for high-mass star formation

A catalogue of 239 ultra-compact H II regions (UCHIIs) found in the CORNISH survey at 5 GHz and 1.5″ resolution in the region 10° < l < 65°, |b| < 1° is presented. This is the largest complete and well-selected sample of UCHIIs to date and provides the opportunity to explore the global and individual properties of this key state in massive star formation at multiple wavelengths. The nature of the candidates was validated, based on observational properties and calculated spectral indices, and the analysis is presented in this work. The physical sizes, luminosities and other physical properties were computed by utilising literature distances or calculating the distances whenever a value was not available. The near- and mid-infrared extended source fluxes were measured and the extinctions towards the UCHIIs were computed. The new results were combined with available data at longer wavelengths and the spectral energy distributions (SEDs) were reconstructed for 177 UCHIIs. The bolometric luminosities obtained from SED fitting are presented. By comparing the radio flux densities to previous observational epochs, we find about 5% of the sources appear to be time variable. This first high-resolution area survey of the Galactic plane shows that the total number of UCHIIs in the Galaxy is ~750 – a factor of 3–4 fewer than found in previous large area radio surveys. It will form the basis for future tests of models of massive star formation.
Reduced contraction strength with increased intracellular [Ca2+] in left ventricular trabeculae from failing rat hearts

Intracellular calcium ([Ca2+]i) and isometric force were measured in left ventricular (LV) trabeculae from spontaneously hypertensive rats (SHR) with failing hearts and normotensive Wistar‐Kyoto (WKY) controls. At a physiological stimulation frequency (5 Hz), and at 37 °C, the peak stress of SHR trabeculae was significantly (P≤; 0.05) reduced compared to WKY (8 ± 1 mN mm−2(n= 8)vs. 21 ± 5 mN mm−2(n= 8), respectively). No differences between strains in either the time‐to‐peak stress, or the time from peak to 50 % relaxation were detected. Measurements using fura‐2 showed that in the SHR both the peak of the Ca2+ transient and the resting [Ca2+]i were increased compared to WKY (peak: 0.69 ± 0.08 vs. 0.51 ± 0.08 μm (P≤ 0.1) and resting: 0.19 ± 0.02 vs. 0.09 ± 0.02 μm (P≤ 0.05), SHR vs. WKY, respectively). The decay of the Ca2+ transient was prolonged in SHR, with time constants of: 0.063 ± 0.002 vs. 0.052 ± 0.003 s (SHR vs. WKY, respectively). Similar results were obtained at 1 Hz stimulation, and for [Ca2+]o between 0.5 and 5 mm. The decay of the caffeine‐evoked Ca2+ transient was slower in SHR (9.8 ± 0.7 s (n= 8)vs. 7.7 ± 0.2 s (n= 8) in WKY), but this difference was removed by use of the SL Ca2+‐ATPase inhibitor carboxyeosin. Histological examination of transverse sections showed that the fractional content of perimysial collagen was increased in SHR compared to WKY (18.0 ± 4.6 % (n= 10)vs. 2.9 ± 0.9 % (n= 11) SHR vs. WKY, respectively). Our results show that differences in the amplitude and the time course of the Ca2+ transient between SHR and WKY do not explain the reduced contractile performance of SHR myocardium per se. Rather, we suggest that, in this animal model of heart failure, contractile function is compromised by increased collagen, and its three‐dimensional organisation, and not by reduced availability of intracellular Ca2+.
3D-XY critical behavior of CsMnF3 from static and dynamic thermal properties

Static and dynamic critical behavior of the easy-plane antiferromagnet CsMnF3 have been studied by means of a high-resolution ac photopyroelectric calorimeter. Thermal diffusivity, thermal conductivity and specific heat have been carefully measured in the near vicinity of the antiferromagnetic to paramagnetic transition (51.1 K). Specific heat and thermal diffusivity show singularities at the Néel temperature while thermal conductivity does not. Both the static and dynamic critical parameters agree with the standard 3D-XY universality class (α = −0.014, A+/A− = 1.06): for specific heat α = −0.016, A+/A− = 1.09 and for thermal diffusivity b = −0.010, U+/U− = 1.09. As the dynamic critical behavior of thermal diffusivity has not yet been theoretically established for the 3D-XY universality class, an approximate equation relating static and dynamic critical parameters has been obtained for it, leading to b ≈ α and A+/A−≈ U+/U− by studying the asymptotic behavior of the functions. This equation has also been experimentally verified for another XY antiferromagnet (SmMnO3). As an easy-plane antiferromagnet with a hexagonal structure, CsMnF3 could have been expected to comply with the 3D-XY chiral class (α = +0.34, A+/A− = 0.36) (as is the case of CsMnBr3), but the experimental results rule out that possibility. This is attributed to the presence of a small in-plane anisotropy of the spins in CsMnF3, which breaks the chiral degeneracy of the 120° spin structure.
Multiscale Entropy Analysis of the Differential RR Interval Time Series Signal and Its Application in Detecting Congestive Heart Failure

Cardiovascular systems essentially have multiscale control mechanisms. Multiscale entropy (MSE) analysis permits the dynamic characterization of the cardiovascular time series for both short-term and long-term processes, and thus can be more illuminating. The traditional MSE analysis for heart rate variability (HRV) is performed on the original RR interval time series (named as MSE_RR). In this study, we proposed an MSE analysis for the differential RR interval time series signal, named as MSE_dRR. The motivation of using the differential RR interval time series signal is that this signal has a direct link with the inherent non-linear property of electrical rhythm of the heart. The effectiveness of the MSE_RR and MSE_dRR were tested and compared on the long-term MIT-Boston’s Beth Israel Hospital (MIT-BIH) 54 normal sinus rhythm (NSR) and 29 congestive heart failure (CHF) RR interval recordings, aiming to explore which one is better for distinguishing the CHF patients from the NSR subjects. Four RR interval length for analysis were used ( N = 500 , N = 1000 , N = 2000 and N = 5000 ). The results showed that MSE_RR did not report significant differences between the NSR and CHF groups at several scales for each RR segment length type (Scales 7, 8 and 10 for N = 500 , Scales 3 and 10 for N = 1000 , Scales 2 and 3 for both N = 2000 and N = 5000 ). However, the new MSE_dRR gave significant separation for the two groups for all RR segment length types except N = 500 at Scales 9 and 10. The area under curve (AUC) values from the receiver operating characteristic (ROC) curve were used to further quantify the performances. The mean AUC of the new MSE_dRR from Scales 1–10 are 79.5%, 83.1%, 83.5% and 83.1% for N = 500 , N = 1000 , N = 2000 and N = 5000 , respectively, whereas the mean AUC of MSE_RR are only 68.6%, 69.8%, 69.6% and 67.1%, respectively. The five-fold cross validation support vector machine (SVM) classifier reports the classification Accuracy ( A c c ) of MSE_RR as 73.5%, 75.9% and 74.6% for N = 1000 , N = 2000 and N = 5000 , respectively, while for the new MSE_dRR analysis accuracy was 85.5%, 85.6% and 85.6%. Different biosignal editing methods (direct deletion and interpolation) did not change the analytical results. In summary, this study demonstrated that compared with MSE_RR, MSE_dRR reports better statistical stability and better discrimination ability for the NSR and CHF groups.
LPA66 Is Required for Editing psbF Chloroplast Transcripts in Arabidopsis1[W][OA]

To gain insight into the molecular mechanism of RNA editing, we have characterized the low psii accumulation66 (lpa66) Arabidopsis (Arabidopsis thaliana) mutant, which displays a high chlorophyll fluorescence phenotype. Its perturbed chlorophyll fluorescence is reflected in reduced levels of photosystem II (PSII) proteins. In vivo protein labeling showed that synthesis rates of the PSII reaction center protein D1/D2 were lower, and turnover rates of PSII core proteins higher, than in wild-type counterparts. The assembly of newly synthesized proteins into PSII occurs in the lpa66 mutant but with reduced efficiency compared with the wild type. LPA66 encodes a chloroplast protein of the pentatricopeptide repeat family. In lpa66 mutants, editing of psbF that converts serine to phenylalanine is specifically impaired. Thus, LPA66 is specifically required for editing the psbF transcripts in Arabidopsis, and the amino acid alternation due to lack of editing strongly affects the efficiency of the assembly of PSII complexes.
The Risk for Coronary Heart Disease According to Insulin Resistance with and without Type 2 Diabetes

Objective. To examine the role of insulin resistance versus hyperglycemia in the risk for coronary heart disease (CHD) and to explore the interaction of insulin resistance with hyperglycemia. Methods. This is a cross-sectional study based on the National Health and Nutrition Examination Survey III (NHANES). 4,825 subjects were selected from 9,737 adults aged 340 years excluding those with fasting <8 hours, type 1 diabetes, pregnancy, or missing data. Insulin resistance was calculated using the HOMA II and then log-transformed (log IR). Odds ratios (OR) of CHD was obtained with multiple logistic regression with reference to non-diabetics with log IR > 1. Results. CHD and type 2 diabetes were present in 9.1 % and 10.5%. Elevated insulin resistance was common; diabetics and non-diabetics with log IR > 1 constituted 6.3% and 12.1% of the population, respectively. ORs for CHD increased as insulin resistance increased in both non-diabetic and diabetics. When log IR > 1, the risk for CHD was not different between diabetics and non-diabetics (OR 1.12, 95% CI; 0.76–1.65). Furthermore, the risk for CHD was higher in non-diabetics with log IR > 1 than in diabetics with log IR1 (OR 0.55, 95% CI; 0.36–0.85). Conclusions. Insulin resistance was a greater risk for CHD than type 2 diabetes. Non-diabetics can have a higher risk for CHD than diabetics when insulin resistance is elevated. More research is warranted to develop strategies to identify and treat insulin resistance.
Omental grafting: a cell‐based therapy for blood vessel repair

Clinicians regularly transplant omental pedicles to repair a wide variety of injured tissues, but the basic mechanism underlying this efficacious procedure is not understood. One possibility that has not been addressed is the ability of omentum to directly contribute regenerative cells to injured tissues. We hypothesized that if omental progenitor cells could be mobilized to incorporate into damaged tissue, the power of this therapy would be greatly expanded. Labelled omental grafts were transplanted into a murine carotid artery injury model. Selected grafts were treated with thymosin β4 (Tβ4) prior to transplantation to investigate the effects of chemical potentiation on healing. We found treatment of grafts with Tβ4‐induced progenitor cells to fully integrate into the wall of injured vessels and differentiate into vascular smooth muscle. Myographic studies determined that arteries receiving Tβ4‐stimulated grafts were functionally indistinguishable from uninjured controls. Concurrent in vitro analyses showed that Tβ4 promoted proliferation, migration and trans‐differentiation of cells via AKT signalling. This study is the first to demonstrate that omentum can provide progenitor cells for repair, thus revealing a novel and naturally occurring source of vascular smooth muscle for use in cell‐based therapies. Furthermore, our data show that this system can be optimized with inducing factors, highlighting a more powerful therapeutic potential than that of its current clinical application. This is a paradigm‐setting concept that lays the foundation for the use of chemical genetics to enhance therapeutic outcomes in a myriad of fields. Copyright © 2012 John Wiley & Sons, Ltd.
A Comparison of the Language Skills of ELLs and Monolinguals Who Are Poor Decoders, Poor Comprehenders, or Normal Readers

The overall objective of this article is to examine how oral language abilities relate to reading profiles in English language learners (ELLs) and English as a first language (EL1) learners, and the extent of similarities and differences between ELLs and EL1s in three reading subgroups: normal readers, poor decoders, and poor comprehenders. The study included 100 ELLs and 50 EL1s in Grade 5. The effect of language group (ELL/EL1) and reading group on cognitive and linguistic skills was examined. Except for vocabulary, there was no language group effect on any measure. However, within ELL and EL1 alike, significant differences were found between reading groups: Normal readers outperformed the two other groups on all the oral language measures. Distinct cognitive and linguistic profiles were associated with poor decoders and poor comprehenders, regardless of language group. The ELL and EL1 poor decoders outperformed the poor comprehenders on listening comprehension and inferencing. The poor decoders displayed phonological-based weaknesses, whereas the poor comprehenders displayed a more generalized language processing weakness that is nonphonological in nature. Regardless of language status, students with poor decoding or comprehension problems display difficulties with various aspects of language.
Structured Sound Based Language for Emotional Robotic Communicative Interaction

Sound is perhaps the most elementary and yet common communication vehicle used by humans and animals alike. Similarly, reactive robots that are based on animal intelligence require real-time simple communication mechanisms to imitate their animal examples. However, emotions are not often considered in developing reactive robots interaction rules and communication. Therefore, these robots, unlike their natural examples, are not capable of expressing basic emotions such as happiness and excitement, fear and stress, anger or contentment as the case with many animals
Asians are different from Caucasians and from each other in their body mass index/body fat per cent relationship

The objective was to study the relationship between body mass index (BMI) and body fat per cent (BF%) in different population groups of Asians. The study design was a literature overview with special attention to recent Asian data. Specific information is provided on Indonesians (Malays and Chinese ancestry), Singaporean Chinese, Malays and Indians, and Hong Kong Chinese. The BMI was calculated from weight and height and the BF% was determined by deuterium oxide dilution, a chemical‐for‐compartment model, or dual‐energy X‐ray absorptiometry. All Asian populations studied had a higher BF% at a lower BMI compared to Caucasians. Generally, for the same BMI their BF% was 3–5% points higher compared to Caucasians. For the same BF% their BMI was 3–4 units lower compared to Caucasians. The high BF% at low BMI can be partly explained by differences in body build, i.e. differences in trunk‐to‐leg‐length ratio and differences in slenderness. Differences in muscularity may also contribute to the different BF%/BMI relationship. Hence, the relationship between BF% and BMI is ethnic‐specific. For comparisons of obesity prevalence between ethnic groups, universal BMI cut‐off points are not appropriate.
Design of Multilayer Balun Filter With Independently Controllable Dual Passbands

In this letter, a novel multilayer dual-band balun filter using two dual-mode cross-slotted patch resonators placed back-to-back is proposed by converting two-port bandpass filter to a three port device. The operation frequency and bandwidth in each passband can be individually controlled, which is a new design concept for a dual-band balun filter. The detailed design procedure based on the coupling matrix is theoretically presented. A transmission zero between the two passbands is realized to improve the band to band isolation; meanwhile a good unbalanced to balanced conversion in both bands is realized. To demonstrate the design methodology, a dual-band balun filter is designed and fabricated. The measured results show good agreement with the simulation data.
