Fault diagnosis using LP-TPG for Random Logic circuits

The proposed Built-In Self-Diagnosis method (BISD) is based on the standard BIST architecture and can be integrated with recent, commercial DFT techniques, LP-TPG for in-field testing and in-field diagnostic data collection. To find maximum faults, structural diagnosis is used which does reveal the diagnostic information. A new low power test pattern generator using a linear feedback shift register (LFSR), called LP-TPG, is used instead normal TPG to reduce the average and peak power of a circuit during test. LP-TPG inserts intermediate patterns between the random patterns. The goal of having intermediate patterns is to reduce the transitional activities of primary inputs which eventually reduces the switching activities inside the circuit under test, and hence, power consumption. The random natures of the test patterns are kept intact. The area overhead of the additional components to the LFSR is negligible compared to the large circuit sizes. In this paper a diagnosis technique and a new LP-TPG are presented, which for the first time overcomes the disadvantages of the above architectures and methods. It is based on the standard STUMPS architecture and thus can be used with the standard tool chains, LP-TPG and synthesis flows. Yet, it overcomes the necessity of repeated tests and extra bandwidth by adding a small response memory and slightly modifying the BIST controller. Modifying the LFSR, by adding weights to tune the pseudorandom vectors for various probabilities, decrease energy consumption and increases fault coverage. The resulting failure information can be read out upon test completion and is input to the proposed diagnosis technique. The method is not confined to the stuck-at fault model, but is able to cover a large variety of defects. The diagnostic success of the method is even superior to that typically achieved in external testing.
Fixed Point Iteration Method

We discuss the problem of finding approximate solutions of the equation x)0 f()0 (1) In some cases it is possible to find the exact roots of the equation (1) for example when f(x) is a quadratic on cubic polynomial otherwise, in general, is interested in finding approximate solutions using some numerical methods. Here, we will discuss a method called fixed point iteration method and a particular case of this method called Newton’s method
Fast measurement by integrating model-based methods and advanced test-cell automation

Modern calibration engine control unit requires a huge number of measurements to fill their maps. Steady state measurements at the engine test bed are still very important to find the optimal settings of all control parameters for an engine operating point. Model-based methods - like design of experiments - are more and more used to reduce the needed numbers of experiments for an engine calibration. Nevertheless, since the number of controllable engine parameters arises, new methods for accelerating each measurement are needed. This paper presents methods to shorten the measurement time by using transitions between measurement points and avoidance of stabilization
3D object matching based on local feature combined with color

3D object matching from cluttered scences is a great project. In order to reduce computational complexity, local feature must be extracted from a small number of keypoints with rich feature. In this paper, we present an algorithm for 3D object matching based on local feature combined with color. Keypoints should be detected first, and then calculate the quality for each keypoint, we choice these high quality keypoints to extract local features. Before finding correspondences between database and the query object in the scences, features should be projected to a PCA subspace. Color information is also considered as threshold to remove the error mathing points, each of the remaining matching points gives a transformation which aligns the object in the scences and the model. K-means algorithm is used to calculate the final correspondences between the query and database object. Experiences is also made to test and verify the method.
Scene analysis for fire detection

Scene analysis is an important component of vision systems. This paper proposes a computationally efficient background modeling method based on a non-parameter statistical test. The image colors and temporal motion are integrated to capture both the temporal and spatial context of the video sequence. An updating scheme is applied for automatic maintenance of the background corners. An experiment designed for fire detection in video surveillance demonstrates that the model can solve the problems including change of illumination, short period of occlusion and small motion of background objects.
Minority Stress and Substance Use in Lesbian, Gay, Bisexual, Queer, and Questioning Adults: An Exploration of Outness and Family Attachment

Carolyn Tompsett, Co-Advisor Harold Rosenberg, Co-Advisor The minority stress model (Meyer, 1995, 2003) may explain the higher rates of substance use found in some lesbian, gay, bisexual, queer and questioning (LGBQ) individuals compared to non-LGBQ individuals. Guided by the model and previous research, I examined whether outness about one’s sexual orientation and attachment to family of origin moderated the relationship between minority stress and substance use in LGBQ adults. To evaluate my hypotheses, I recruited two samples of LGBQ participants, one using social media (N=341) and another using a classified ad website (N=180), to answer questions about their drug and alcohol use, level of outness, experiences of minority stress, and attachment to family of origin. As predicted, higher levels of minority stress were significantly, albeit weakly, correlated with higher rates of substance use. However, contrary to expectations, stronger family attachment and higher level of outness were not associated with lower substance use in either sample. Instead, participants who reported higher levels of outness were more likely to report problem drug use. Because reported substance use was considerably lower than I expected in both samples, my study may not have provided a sensitive test of the hypotheses. The results could indicate that rates of substance use by LGBQ individuals are declining, and failed to support the hypothesis that strong family attachment is associated with lower rates of substance use in LGBQ adults. Further research should evaluate how LGBQ people mitigate minority stress other than by self-medicating with alcohol and drug use.
Computation of stable interval Kalman filter bounds for their use in robust state estimation for an uninhabited surface vehicle with bounded indeterminate system dynamics

This paper implements an interval Kalman filter (IKF) for the navigation of the Springer uninhabited surface vehicle. Interval filters become necessary when the system dynamics are not known precisely or vary unpredictably, but can nevertheless be described in terms of bounded intervals. Such filters based on interval systems require the use of interval arithmetic (IA) for their operation. One of the main limitations to such techniques is that the interval bounds of the computed filter estimates often diverge due to the overly conservative nature of IA. In this paper, ellipsoidal rather than direct IA is used to operate the IKF and obtain bounds of the interval estimates that do not diverge due to the so called wrapping effect. From these bounds, a weighted average is computed at each time-step that is close to the true system state. To obtain this weighting, an artificial neural network (ANN) is previously trained to map residuals of an ordinary Kalman filter to the optimal weights, and this trained network is then used online in new tracking missions.
“Friend” or Foe? Why People Friend Disliked Others on Facebook

This study explores the disconnection that exists between the number of friends and relationships people maintain in their face-to-face interactions and the number of connections people establish on social networking sites. Specifically, we examined the extent to which Facebook users “friend” people they dislike and find annoying on Facebook and the reasons people offer for engaging in these seemingly nonintuitive behaviors. The results indicate that, in a sample of college students (N = 305), the majority of Facebook users are friends with people they dislike on Facebook (61%) and actively read the postings of individuals even though they find their postings annoying (85%). Participants’ sex, intensity of Facebook use, and general relational anxiety all independently predicted the occurrence of friending disliked others and actively reading annoying postings. A uses and gratifications framework was adopted to develop a typology of reasons why people engage in these behaviors. Monitoring, surveillance, downward social comparison, and other explanations were provided by participants to account for their behavior on Facebook. How engaging in these online behaviors might affect the psychological well-being of individuals and quality of interpersonal relationships is discussed, and future directions for research are offered.
21 Band 1/3-Octave Filter bank for digital hearing aids

ANSI S1.11 1/3 Octave Filter bank is popular in acoustic applications due to well matching the frequency characteristics of human ears. However high computation complexity limits its usage. This paper deals with the digital hearing aids which consumes less power and cover the human voiced speech frequency correctly. The technique called the complexity-effective multirate FIR filter bank algorithm with a systematic coefficient design flow is proposed to reduce the order of the filter. In existing method 18 bands were used. It cover the frequency range from 140Hz to 8979Hz. It didn't cover the human voice frequency fully. Because the voiced speech of a typical adult male starts from 80Hz to 145Hz. Here 21 bands are used with Finite Impulse Response (FIR) filters. This filter has been simulated in Synopsys. The proposed method consumes less power which is 30%-79% less of other methods and cover the human voiced speech frequency.
Is the Bursting Radio Source GCRT J1745–3009 a Double Neutron Star Binary?

GCRT J1745-3009 is a peculiar transient radio source in the direction of the Galactic center. It was observed to emit a series of ~1 Jy bursts at 0.33 GHz, with a typical duration of ~10 minutes and at apparently regular intervals of ~77 minutes. If the source is indeed at the distance of the Galactic center, as seems likely, we show that its observational properties are compatible with those expected from a double neutron star binary, similar to the double pulsar system J0737-3039. In the picture we propose, the (coherent) radio emission comes from the shock originating in the interaction of the wind of the more energetic pulsar with the magnetosphere of the companion. The observed modulation of the radio signal is the consequence of an eccentric orbit, along which the separation between the two stars varies. This cyclically drives the shock inside the light-cylinder radius of the less energetic pulsar.
Parvovirus B19 NS1 protein induces cell cycle arrest at G2-phase by activating the ATR-CDC25C-CDK1 pathway

Human parvovirus B19 (B19V) infection of primary human erythroid progenitor cells (EPCs) arrests infected cells at both late S-phase and G2-phase, which contain 4N DNA. B19V infection induces a DNA damage response (DDR) that facilitates viral DNA replication but is dispensable for cell cycle arrest at G2-phase; however, a putative C-terminal transactivation domain (TAD2) within NS1 is responsible for G2-phase arrest. To fully understand the mechanism underlying B19V NS1-induced G2-phase arrest, we established two doxycycline-inducible B19V-permissive UT7/Epo-S1 cell lines that express NS1 or NS1mTAD2, and examined the function of the TAD2 domain during G2-phase arrest. The results confirm that the NS1 TAD2 domain plays a pivotal role in NS1-induced G2-phase arrest. Mechanistically, NS1 transactivated cellular gene expression through the TAD2 domain, which was itself responsible for ATR (ataxia-telangiectasia mutated and Rad3-related) activation. Activated ATR phosphorylated CDC25C at serine 216, which in turn inactivated the cyclin B/CDK1 complex without affecting nuclear import of the complex. Importantly, we found that the ATR-CHK1-CDC25C-CDK1 pathway was activated during B19V infection of EPCs, and that ATR activation played an important role in B19V infection-induced G2-phase arrest.
Biochemical markers in the surgical intensive care : Identifying critically ill surgical patients with complications

markdownabstract__Abstract__ Introductie Patienten die postoperatief op de intensive care (IC) worden opgenomen hebben een hogere kans op het ontwikkelen van complicaties. Het is belangrijk om deze complicaties vroegtijdig te kunnen identificeren bij de kritiek zieke chirurgische patienten op de IC om tijdig adequate therapie te kunnen starten. Hierom bestudeerden wij de klinische voorspellende waarde van dagelijks gebruikte biomarkers C-reactief proteine CRP), lactaat, procalcitonine (PCT) en de Sequential Organ Failure Assessment score (SOAF) bij het aantonen van chirurgische complicaties bij de algemene postoperatieve patient tijdens de IC-opname. Resultaten Er wordt geen significante correlatie tussen stijging van CRP en interventies gevonden. Dit bevestigd het vermoeden dat artsen vaak getriggerd worden door deze markers om interventies te verrichten bij de kritiek zieke postoperatieve patienten. Toch wordt er geen relatie gevonden tussen stijging in CRP-concentraties en chirurgische complicaties. Wanneer gekeken wordt naar het gebruik van lactaat als voorspeller van complicaties, dan vinden we dat dit marker ook geen geschikt prognostisch instrument is voor chirurgische complicaties op de IC. Een relatief nieuwere maker is procalcitonine. Ondanks resultaten in eerder studies welke een positieve correlatie tussen PCT-stijging en complicaties toonden, konden we dit niet reproduceren in onze groep algemeen chirurgische patienten op de IC. In deze studie konden we de conclusie trekken dat PCT geen geschikte marker is om chirurgische complicaties in een heterogene kritiek zieke postoperatieve groep patienten op de IC te identificeren. Indien we alle parameters in een regressie model combineren, dan bevestigt het model de eerdere bevindingen waarbij geen enkel parameter afzonderlijk adequaat blijkt te zijn om die kritiek zieke patient met verhoogd kans op complicaties te identificeren. Het model benadrukt dat zelfs bij een combinatie van parameters er geen betere voorspellende waardes voor chirurgische complicaties kan worden bereikt bij het gebruik van de huidige biomarkers. Conclusie Tot heden worden artsen duidelijk getriggerd door parameters zoals C-reactief proteine, lactaat, procalcitonine en het klinische scoringssysteem Sequential Organ Failure Assessment Score. Echter, deze markers zijn niet geschikt als prognostische testen voor de vroegtijdige identificatie van chirurgische complicaties in kritiek zieke chirurgische patienten tijdens de intensive care opname.
Run-and-tumble particles in speckle fields

The random energy landscapes developed by speckle fields can be used to confine and manipulate a large number of micro-particles with a single laser beam. By means of molecular dynamics simulations, we investigate the static and dynamic properties of an active suspension of swimming bacteria embedded into speckle patterns. Looking at the correlation of the density fluctuations and the equilibrium density profiles, we observe a crossover phenomenon when the forces exerted by the speckles are equal to the bacteria’s propulsion.
Analysis of force-deconvolution methods in frequency-modulation atomic force microscopy

In frequency-modulation atomic force microscopy the direct observable is the frequency shift of an oscillating cantilever in a force field. This frequency shift is not a direct measure of the actual force, and thus, to obtain the force, deconvolution methods are necessary. Two prominent methods proposed by Sader and Jarvis (Sader–Jarvis method) and Giessibl (matrix method) are investigated with respect to the deconvolution quality. Both methods show a nontrivial dependence of the deconvolution quality on the oscillation amplitude. The matrix method exhibits spikelike features originating from a numerical artifact. By interpolation of the data, the spikelike features can be circumvented. The Sader–Jarvis method has a continuous amplitude dependence showing two minima and one maximum, which is an inherent property of the deconvolution algorithm. The optimal deconvolution depends on the ratio of the amplitude and the characteristic decay length of the force for the Sader–Jarvis method. However, the matrix method generally provides the higher deconvolution quality.
Comparison of major dish item and food group consumption between normal and obese Korean children: application to development of a brief food frequency questionnaire for obesity-related eating behaviors

This study sought to compare intake levels of major dish items and food groups between normal and obese Korean children in order to understand obesity-related eating behaviors. The study was also conducted to apply the information on the differences in major dish items and food groups found in this study to development of a brief food frequency questionnaire (FFQ) for children's obesity-related eating behaviors. Finally, the developed FFQ was evaluated for reliability. A total of 290, 24-hour dietary recall data from 9-11 year-old normal or obese participants in the 2001 Korean National Health and Nutrition Examination Survey (KNHANES) were reviewed to identify dish items and food groups showing outstanding differences between the normal and obese groups. Based on the level of intake amount between the two groups, a total of 7 items, including ddeokbokggi, spaghetti, ham roast, pork cutlet, dairy products & ices, kimchi, and fruits, were selected to be included in the FFQ. The former 5 items were seen to be consumed more in the obese group, while the latter 2 items were so in the normal group. The questionnaire was formatted into a frequency response section of a seven-category option and reference period of the last 7 days. Test-retest reliability of the developed FFQ was examined by administering it to 153, 9-11 year-old children at a public elementary school in Seoul twice at a month interval. The level of reliability was found to be reasonably high. In conclusion, this study suggests that high consumption of several high-calorie dish items and low consumption of kimchi and fruits may be important eating behaviors in relation to obesity risk among 9-11 year-old children who need nutrition educators' attention. The current study also implies that a simple FFQ can be utilized to reliably assess 9-11 year-old children's diets.
Optimizing Energy to Minimize Errors in Approximate Ripple Carry Adders

We present a theoretical foundation and a methodology for automatically assigning supply voltages to approximate ripple carry adders in which accuracy is traded for energy consumption. The error minimization problem for a fixed energy budget is formulated as a binned geometric program. We first use geometric programming to minimize the average error of the adder and compute the supply voltages at the gate level, after which we bin the voltages to a finite set (of four or five voltages) using a heuristic. Using HSPICE in 90nm technology, we show simulation results by applying our methodology to a ripple carry adder and obtain savings of up to 2:58X (and by a median of 1:58X) in average error, when compared to uniform voltage scaling, for the same energy consumption. Compared to a naive biased voltage scaling (n-BIVOS), which is the best prior art in literature, a Binned Geometric Program Solution (BGPS) as proposed in this paper saves 32.3% energy with the same PSNR in an 8point FFT example or, alternatively, increases the PSNR by 8.5db for the same energy consumption for the FFT.
Seismological constraints on the high-gravity DOV stars PG2131+066 and PG 1707+427

A seismological study of the pulsating PG1159 stars PG2131+066 and PG 1707+427 is presented. We perform extensive adiabatic computations of g-mode pulsation periods of PG1159 evolutionary models with stellar masses ranging from 0.530 to 0.741 M⊙. We constrain the stellar mass of PG2131+066 and PG 1707+427 by comparing the observed period spacing of each star with the theoretical asymptotic period spacings and with the average of the computed period spacings. We also employ the individual observed periods to find representative seismological models for both stars.
Ketamine and Depression: A Review

40 Ryan, Marta, & Koek , 33(2), 2014, pp. 40-74 Ketamine, via intravenous infusions, has emerged as a novel therapy for treatment-resistant depression, given rapid onset and demonstrable efficacy in both unipolar and bipolar depression. Duration of benefit, on the order of days, varies between these subtypes, but appears longer in unipolar depression. A unique property is reduction in suicidality although data are more limited. Strategies to extend duration, via multiple doses, maintenance treatment, or subsequent augmenting medications have yielded mixed results. There is a relative paucity of data regarding alternate methods of administration such as intramuscular, intranasal, and oral routes, though preliminary results are promising. Adverse effects most reliably incl ude dissociative and sympathomimetic effects, both transient and mild, and suggest good tolerability. Ketamine's unique effects may represent an opportunity for a paradigm shift in the pharmacologic treatment of depression. Wesley C. Ryan University of Washington Seattle, WA, USA
Unusual Metastases from a Pleomorphic Adenoma of the Parotid Gland: A Case and Literature's Review

Background: Pleomorphic adenoma constitutes the most common benign parotid gland tumor. Local recurrence after surgery has been described in 1%-5% of cases, and malignant evolution in 2%-9% of cases. Metastasizing pleomorphic adenomas has rarely been reported. No histologic or molecular parameters exist at the present time that could predict the development of metastasis in these neoplasms. Methods and Results: A 54-year-old woman had a superficial left parotidectomy with facial nerve preservation for pleomorphic adenoma. She developed two recurrences in 2000 and 2001, but 25 years later the first operation she presented a metastasis in her right gluteal region with evidence of local recurrence. Conclusion: Metastatizing pleomorphic adenoma is a rare pathologic situation but, in case of swelling or lump appearance in patients with pleomorphic adenoma history, it should be taken in mind.
