TCG: a transitive closure graph-based representation for non-slicing floorplans

In this paper, we propose a transitive closure graph-based representation for general floorplans, called TCG, and show its superior properties. TCG combines the advantages of popular representations such as sequence pair, BSG, and B*-tree. Like sequence pair and BSG, but unlike O-tree, B*-tree, and CBL, TCG is P-admissible. Like B*-tree, but unlike sequence pair, BSG, O-tree, and CBL, TCG does not need to construct additional constraint graphs for the cost evaluation during packing, implying faster runtime. Further, TCG supports incremental update during operations and keeps the information of boundary modules as well as the shapes and the relative positions of modules in the representation. More importantly, the geometric relation among modules is transparent not only to the TCG representation but also to its operations, facilitating the convergence to a desired solution. All these properties make TCG an effective and flexible representation for handling the general floorplan/placement design problems with various constraints. Experimental results show the promise of TCG.
Effects of neonatal fentanyl on late adolescent opioid-mediated behavior

Introduction Because of the steady increase in the use of synthetic opioids in women of childbearing age, a large number of children are at risk of exposure to these drugs prenatally or postnatally through breast milk. While there is older literature looking at the effects of morphine and heroin, there are relatively few studies looking at the long-term effects of high-potency synthetic opioid compounds like fentanyl. Thus, in the present study, we assessed whether brief exposure to fentanyl in male and female rat pups during a period roughly equivalent to the third trimester of CNS development altered adolescent oral fentanyl self-administration and opioid-mediated thermal antinociception. Methods We treated the rats with fentanyl (0, 10, or 100 μg/kg sc) from postnatal day (PD) 4 to PD 9. The fentanyl was administered daily in two injections given 6 h apart. After the last injection on PD 9, the rat pups were left alone until either PD 40 where they began fentanyl self-administration training or PD 60 where they were tested for morphine- (0, 1.25, 2.5, 5, or 10 mg/kg) or U50,488- (0, 2.5, 5, 10, or 20 mg/kg) induced thermal antinociception. Results In the self-administration study, we found that female rats had more active nose pokes than male rats when receiving a fentanyl reward but not sucrose alone solution. Early neonatal fentanyl exposure did not significantly alter fentanyl intake or nose-poke response. In contrast, early fentanyl exposure did alter thermal antinociception in both male and female rats. Specifically, fentanyl (10 μg/kg) pre-treatment increased baseline paw-lick latencies, and the higher dose of fentanyl (100 μg/kg) reduced morphine-induced paw-lick latencies. Fentanyl pre-treatment did not alter U50,488-mediated thermal antinociception. Conclusions Although our exposure model is not reflective of typical human fentanyl use during pregnancy, our study does illustrate that even brief exposure to fentanyl during early development can have long-lasting effects on mu-opioid-mediated behavior. Moreover, our data suggest that females may be more susceptible to fentanyl abuse than males.
Moving Object Detection Based on Edge Pair Difference

We present an improved method to detect moving object and obtain the relative accurate location in this paper. The Canny detector is applied to detect the edge of image, which is the edge difference of continuous frames. Then we utilize the pair of moving object information to reach a good detection of the moving object and location. The extensive experiments show that our method is efficient to the moving object detection.
Thermal Conductance at Atomically Clean and Disordered Silicon/Aluminum Interfaces: A Molecular Dynamics Simulation Study

Thermal resistance between layers impedes effective heat dissipation in electronics packaging applications. Thermal conductance for clean and disordered interfaces between silicon (Si) and aluminum (Al) was computed using realistic Si/Al interfaces and classical molecular dynamics with the modified embedded atom method potential. These realistic interfaces, which include atomically clean as well as disordered interfaces, were obtained using density functional theory. At 300 K, the magnitude of interfacial conductance due to phonon-phonon scattering obtained from the classical molecular dynamics simulations was approximately five times higher than the conductance obtained using analytical elastic diffuse mismatch models. Interfacial disorder reduced the thermal conductance due to increased phonon scattering with respect to the atomically clean interface. Also, the interfacial conductance, due to electron-phonon scattering at the interface, was greater than the conductance due to phonon-phonon scattering. T.
Demonstration of sawtooth period locking with power modulation in TCV plasmas

Corroborating evidence is presented that the sawtooth period can follow the modulation frequency of an externally applied high power electron cyclotron wave source. Precise, fast and robust open loop control of the sawtooth period with a continuously changing reference period has been achieved. This period locking is not associated with the crash, but with the phase evolution of the inter-crash dynamics. This opens new possibilities of open loop control for physics studies and maybe for reactor performance control.

Rates of editor‐authored manuscripts among urology journals using blinded or non‐blinded review

We compared publication rates of editor‐authored publications between journals that do not blind peer reviewers to author identity with one that does. Our hypothesis was that the if the identity of editors as authors is known to peer reviewers this may potentially bias the recommendation for publication. To do this, we queried Scopus for all publications from five top urology journals from 2013 to 2018, and linked them to a database of editors. Poisson regression analysis was used to compare publication rates of manuscripts with at least one editor as author between blinded journals and a non‐blinded journal. In separate analyses, we compared publication frequency before and after authors became editors and the frequency with which articles were cited. We found that the adjusted rate ratio of editor‐authored manuscripts comparing the non‐blinded journal to the blinded journal was 5.4 (95% CI 3.8–7.6) for ‘total publications’, and 1.9 (95% CI 1.5–2.2) among ‘articles only’. Median citation frequency was slightly higher among articles written by editors compared with non‐editors at 11 (3–26) versus 7 (2–16) (p < 0.001). We concluded that the blinded journal had a smaller representation of their editors as authors of their manuscripts, compared with the non‐blinded journals.
Multibeam half radial line slot array (RLSA) antennas

ABSTRACT An original design of a multibeam Radial Line Slot Array (RLSA) antenna having two beams directed to the broadside and two beams directed to the backside is discussed in this research. The uniqueness of this design is the implementation of multibeam as a half-cut RLSA instead of a full-circle RLSA, which aims to make them more suitable for smaller devices. In order to produce a beam to the backside, the slots were placed on the backside ground plane. Furthermore, the use of the half-circle RLSA and the backside ground plane to generate the beam disrupted the power flow within the antenna’s cavity, which caused a problem of center frequency shift. A frequency design shift technique is then proposed to overcome this problem in this research with the modeling and simulation of 120 four-beams half RLSA in order to determine the most efficient model to be fabricated. The measurements carried out to verify the accuracy of the fabricated model were in good agreement with the simulation results and proved the validity of the antenna design. The result shows the possibility and effectiveness of designing four symmetrical beam antennas with gain of 8.1 dBi, directions of 60°, 150°, 210°, and 330°, and beamwidth of 22°. The gain of 8.1 dBi is 9 dB less than the gain of a single beam antenna, which is consistent with the theory of beam splitting. Moreover, the antenna offers low reflection and broad bandwidth for Wi-Fi needs.
Generalized Binomial Trees

We consider the problem of consistently pricing new options given the prices of related options on the same stock. The Black-Scholes formula and standard binomial trees can only accommodate one related European option which then effectively specifies the volatility parameter. Implied binomial trees can accommodate only related European options with the same time-to-expiration. The generalized binomial trees introduced here can accommodate any kind of related options (European, American, or exotic) with different times-to-expiration.
A Synergetic Strategy for Brand Characterization of Colla Corii Asini (Ejiao) by LIBS and NIR Combined with Partial Least Squares Discriminant Analysis

A synergetic strategy was proposed to address the critical issue in the brand characterization of Colla corii asini (Ejiao, CCA), a precious traditional Chinese medicine (TCM). In all brands of CCA, Dong’e Ejiao (DEEJ) is an intangible cultural heritage resource. Seventy-eight CCA samples (including forty DEEJ samples and thirty-eight samples from other different manufacturers) were detected by laser-induced breakdown spectroscopy (LIBS) and near-infrared spectroscopy (NIR). Partial least squares discriminant analysis (PLS-DA) models were built first considering individual techniques separately, and then fusing LIBS and NIR data at low-level. The statistical parameters including classification accuracy, sensitivity, and specificity were calculated to evaluate the PLS-DA model performance. The results demonstrated that two individual techniques show good classification performance, especially the NIR. The PLS-DA model with single NIR spectra pretreated by the multiplicative scatter correction (MSC) method was preferred as excellent discrimination. Though individual spectroscopic data obtained good classification performance. A data fusion strategy was also attempted to merge atomic and molecular information of CCA. Compared to a single data block, data fusion models with SNV and MSC pretreatment exhibited good predictive power with no misclassification. This study may provide a novel perspective to employ a comprehensive analytical approach to brand discrimination of CCA. The synergetic strategy based on LIBS together with NIR offers atomic and molecular information of CCA, which could be exemplary for future research on the rapid discrimination of TCM.
The positive relationship between androgen receptor splice variant-7 expression and the risk of castration-resistant prostate cancer: A cumulative analysis

Background At present, androgen deprivation therapy (ADT) is still the standard regimen for patients with metastatic and locally advanced prostate cancer (PCa). The level of androgen receptor splice variant-7 (AR-V7) in men with castration-resistant prostate cancer (CRPC) has been reported to be elevated compared with that in patients diagnosed with hormone-sensitive prostate cancer (HSPC). Aim Herein, we performed a systematic review and cumulative analysis to evaluate whether the expression of AR-V7 was significantly higher in patients with CRPC than in HSPC patients. Methods The commonly used databases were searched to identify the potential studies reporting the level of AR-V7 in CRPC and HSPC patients. The association between CRPC and the positive expression of AR-V7 was pooled by using the relative risk (RR) with the corresponding 95% confidence intervals (CIs) under a random-effects model. For detecting the potential bias and the heterogeneity of the included studies, sensitivity analysis and subgroup analysis were performed. Publication bias was assessed Egger’s and Begg’s tests. This study was registered on PROSPERO (ID: CRD42022297014). Results This cumulative analysis included 672 participants from seven clinical trials. The study group contained 354 CRPC patients, while the other group contained 318 HSPC patients. Pooled results from the seven eligible studies showed that the expression of positive AR-V7 was significantly higher in men with CRPC compared to those with HSPC (RR = 7.55, 95% CI: 4.61–12.35, p < 0.001). In the sensitivity analysis, the combined RRs did not change substantially, ranging from 6.85 (95% CI: 4.16–11.27, p < 0.001) to 9.84 (95% CI: 5.13–18.87, p < 0.001). In the subgroup analysis, a stronger association was detected in RNA in situ hybridization (RISH) measurement in American patients, and those studies were published before 2011 (all p < 0.001). There was no significant publication bias identified in our study. Conclusion Evidence from the seven eligible studies demonstrated that patients with CRPC had a significantly elevated positive expression of AR-V7. More investigations are still warranted to clarify the association between CRPC and AR-V7 testing. Systematic review registration https://www.crd. york.ac. uk/prospero/, identifier CRD42022297014.
A new tracking controller for discrete‐time SISO non minimum phase systems

A new tracking controller for discrete‐time Single Input Single Output (SISO) non‐minimum phase (NMP) systems is presented. In the proposed method, after cancelation of poles and cancelable zeros of the system, the controller adds some NMP zeros to compensate the effect of NMP zero (zeros) of the system. As a result, the phase of the overall transfer function will be almost linear and its magnitude approaches unity for all frequencies. The method can be applied even to the systems with complex conjugate NMP zeros. As well, it is applicable to the systems for which the conventional methods cannot properly be used. Furthermore, a generalization of method to continuous‐time systems is another given result. Several examples are provided to illustrate the effectiveness of the method.

LS2W: Implementing the Locally Stationary 2D Wavelet Process Approach in R

Locally stationary process representations have recently been proposed and applied to both time series and image analysis applications. This article describes an implementation of the locally stationary two-dimensional wavelet process approach in R. This package permits construction of estimates of spatially localized spectra and localized autocovariance which can be used to characterize structure within images.
Spatially decaying turbulence and its relation to mixing across density interfaces

The turbulence generated by a vertically oscillating grid in a water tank and the entrainment across a salinity interface caused by this turbulence have been investigated experimentally. Measurements were carried out in a homogeneous layer of fluid as well as a two-layered fluid, which permitted us to determine the decay law of this turbulence and the way in which the structure of the turbulence depends on the mesh size and on the frequency and amplitude of the grid oscillation. It was found that the turbulent kinetic energy decays with distance from the grid according to a power law $\overline{q^2}\propto z^{-n}$, with n close to 2, and that the turbulent Reynolds number remains approximately constant during decay. The linear dependence of the r.m.s. turbulent velocity on the grid oscillation frequency found by Thompson & Turner (1975) in the case of a square-bar grid has been confirmed. It is shown here that this linear relation remains valid when an interface is present and consequently the dependence of the entrainment velocity on the local Richardson number is of the form $u_e/u \propto Ri^{-\frac{3}{2}}$, the Péclet number being high. While the bearing of these results on the problem of the thermocline or an inversion is clear we wish to emphasize that the spatial decay of turbulence is interesting in itself.
Diving into the Resolution Process: Parent’s Reactions to Child’s Diagnosis

This research presents an in-depth observation of parental resolution regarding a child’s diagnosis with special needs to help counsellors understand the complexities of parental coping. Sixty-two parents of children with Autism Spectrum Disorder/Intellectual Developmental Delay participated in a Reaction to the Diagnosis Interview and a semi-structured interview. Categorical analysis revealed that 59.7% of the parents had reached resolution, with approximately 40% emotional orientation, 40% cognitive orientation, and 20% proactive orientation. Content analysis revealed three themes: emotions—feelings of guilt, shame, and emotional breakdown; thoughts—fear of stigma and concern for the child’s future; actions—concealment, seeking support, and attempts to reject the results of the diagnosis. Whereas most parents were diagnosed as having reached resolution, the content analysis still found complex subject matter suggesting lack of resolution. Research findings show that counsellors should identify the intricate emotional dynamics of parents coping while being cautious of premature coping categorization.
Electrical properties of InAsxSb1−x alloys

Measurements have been made of the high-temperature Hall coefficient, electrical conductivity, and thermoelectric power in polycrystalline n-type samples of InAsxSb1−x alloys of extrinsic carrier concentration ~1017/cm3. From the Hall-coefficient data, values of the extrapolated absolute-zero band gap E00 have been determined over the whole alloy range, the thermoelectric power results being used to provide a correction factor to allow for effects of degeneracy. In all cases this correction was found to be very small. The resultant values of E00 for the alloys are somewhat lower than those obtained previously from optical absorption data and show a minimum of 0.17 eV at x ~0.4. From the electrical conductivity data, values of electron mobility μc have been obtained as a function of temperature T and composition x. At all temperatures in the range 0–500 °C, μc is found to vary linearly with x, indicating that the effects of alloy scattering are negligible. For each value of x, μc is found to satisfy the re.
Reliability of checkpointed real-time systems using time redundancy

Real-time computers are often used in embedded, life-critical applications where high reliability is important. A common approach to making such systems dependable is to vote on redundant processors executing multiple copies of the same task is described. The processors which make up such voted systems are subjected not only to independently occurring permanent and transient failure, but also to correlated transients brought about by electromagnetic interference from the operating environment. To counteract these transients, checkpointing and time redundancy are required, in addition to processor redundancy. This work analyzes the use of time and device redundancy in systems subject to correlated failure. The tradeoffs in checkpoint placement in such a system are found to be considerably different from those for non-redundant systems without real-time constraints. The authors compare fault-tolerant designs and without a rollback capability, accounting for the increased hardware-failure rate due to processor duplication when faults are detected in hardware, and the doubled execution times when detection is implemented in software. >
Evaluation of adaptation strengths of CARE Dose 4D in pediatric CT

The motivation of this study is the general lack of knowledge regarding the efficiency and the appropriate use of the adaptation strengths of Siemens automatic exposure control system CARE Dose 4D. The purpose was to evaluate the effect on radiation absorbed dose using different adaptation strengths of CARE Dose 4D in three routine pediatric CT protocols. A pediatric anthropomorphic whole body phantom was used to simulate a 4 year old patient. CT scans were performed with a Siemens SOMATOM Definition Flash using three different pediatric protocols: neck, thorax, and abdomen. The characteristic of the tube current modulation was similar for all adaptation strengths. The difference is the extent of decrease in tube current. The degree of dose reduction using CARE Dose 4D and CARE kV compared using a fix effective mAs was 34-57%, 51-88%, and 56-91% for neck, thorax, and abdomen protocol, respectively. Accordingly, there is a large difference in radiation dose dependent on the adaptation strength: a factor of 1.5, 4.5, and 4.6 for neck, thorax, and abdomen protocol, respectively. The adaptation strengths can be used to obtain user-specified modifications of image quality or radiation dose to the patient. Radiologists and medical physicists need to be aware of the large differences between the adaptation strengths, and such differences are useful when attempting strategies to optimize CT radiation dose.
Converse piezoelectric effect and photoelastic effect in InGaN/GaN multiple quantum wells

We present microphotoluminescence and microRaman measurements with different optical excitation intensities in InGaN/GaN multiple quantum wells (MQWs). When the optical excitation density was increased, the InGaN A1(LO) phonon was found to show a redshift in frequency and a blueshift in photoluminescence spectra has been observed. The change in the refractive index of MQWs was found to be strongly related to the blueshift of photoluminescence spectra and the redshift of the InGaN A1(LO) phonon. Our results firmly establish that a converse piezoelectric effect responsible for a considerable photoelastic effect (change in refractive index produced by a strain) arising from the optical modulation does exist in InGaN/GaN MQWs.
Fast wave current drive: Experimental status and reactor prospects

The fast wave is one of the two possible wave polarizations which propagate according to the basic theory of cold plasmas. It is distinguished from the other (slow wave) branch by having an electric field vector which is mainly orthogonal to the confining magnetic field of the plasma. The plasma and fast wave qualitatively assume different behavior depending on the frequency range of the launched wave. The high frequency fast wave (HFFW), with a frequency (.omega.2.pi. )approximately) GHz) much higher than the ion cyclotron frequency (.cap omega./sub i/), suffers electron Landau damping and drives current by supplying parallel momentum to superthermal electrons in a fashion similar to lower hybrid (slow wave) current drive. In the simple theory the HFFW should be superior to the slow wave and can propagate to very high density and temperature without impediment. Experiments, however, have not conclusively shown that HFFW current drive can be achieved at densities above the slow wave current drive limit, possibly due to conversion of the launched fast waves into slow waves by density fluctuations. Alternatively, the low frequency fast wave (LFFW), with frequencies ()approxreverse arrowlt) 100 MHz) only a few times the ion cyclotron frequency, is damped by electron Landaumore » damping and, in a hot plasma ()approxreverse arrowgt) 10 keV), by electron transit time magnetic pumping; current drive is achieved by pushing superthermal electrons, and efficiency is prediocted to be slightly better than for lower hybrid current drive. Most significantly, the slow wave does not propagate in high density plasma when . omega. )approximately) . cap omega. /sub i/, so parasitic coupling to the slow wave can be avoided, and no density and temperture limitations are foreseen. Experiments with fast wve current drive invariably find current drive efficiency as good as obtained in lower hybrid experiments at comparable, low temperatures. 45 refs., 4 figs., 1 tab« less
