Eight Aging-Related Genes Prognostic Signature for Cervical Cancer

This study searched for aging-related genes (ARGs) to predict the prognosis of patients with cervical cancer (CC). All data were obtained from Molecular Signatures Database, Cancer Genome Atlas, Gene Expression Integration, and Genotype Organization Expression. The R software was used to screen out the differentially expressed ARGs (DE-ARGs) between CC and normal tissues. A protein–protein interaction network was established by the DE-ARGs. The univariate and multivariate Cox regression analyses were conducted on the first extracted Molecular Complex Detection component, and a prognostic model was constructed. The prognostic model was further validated in the testing set and GSE44001 dataset. Prognosis was analyzed by Kaplan–Meier curves, and accuracy of the prognostic model was assessed by receiver operating characteristic area under the curve analysis. An independent prognostic analysis of risk score and some clinicopathological factors of CC was also performed. The copy-number variant (CNV) and single-nucleotide variant (SNV) of prognostic ARGs were analyzed by the BioPortal database. A clinical practical nomogram was established to predict individual survival probability. Finally, we carried out cell experiment to further verify the prognostic model. An eight-ARG prognostic signature for CC was constructed. High-risk CC patients had significantly shorter overall survival than low-risk patients. The receiver operating characteristic (ROC) curve validated the good performance of the signature in survival prediction. The Figo_stage and risk score served as independent prognostic factors. The eight ARGs mainly enriched in growth factor regulation and cell cycle pathway, and the deep deletion of FN1 was the most common CNV. An eight-ARG prognostic signature for CC was successfully constructed.
THE HETDEX PILOT SURVEY. I. SURVEY DESIGN, PERFORMANCE, AND CATALOG OF EMISSION-LINE GALAXIES

We present a catalog of emission-line galaxies selected solely by their emission-line fluxes using a wide-field integral field spectrograph. This work is partially motivated as a pilot survey for the upcoming Hobby–Eberly Telescope Dark Energy Experiment. We describe the observations, reductions, detections, redshift classifications, line fluxes, and counterpart information for 397 emission-line galaxies detected over 169 □′ with a 3500–5800 Å bandpass under 5 Å full-width-half-maximum (FWHM) spectral resolution. The survey's best sensitivity for unresolved objects under photometric conditions is between 4 and 20× 10−17 erg s−1 cm−2 depending on the wavelength, and Lyα luminosities between 3 × 1042 and 6 × 1042 erg s−1 are detectable. This survey method complements narrowband and color-selection techniques in the search of high-redshift galaxies with its different selection properties and large volume probed. The four survey fields within the COSMOS, GOODS-N, MUNICS, and XMM-LSS areas are rich with existing, complementary data. We find 105 galaxies via their high-redshift Lyα emission at 1.9 < z < 3.8, and the majority of the remainder objects are low-redshift [O ii]3727 emitters at z < 0.56. The classification between low- and high-redshift objects depends on rest-frame equivalent width (EW), as well as other indicators, where available. Based on matches to X-ray catalogs, the active galactic nuclei fraction among the Lyα emitters is 6%. We also analyze the survey's completeness and contamination properties through simulations. We find five high-z, highly significant, resolved objects with FWHM sizes >44 □′ which appear to be extended Lyα nebulae. We also find three high-z objects with rest-frame Lyα EW above the level believed to be achievable with normal star formation, EW0>240 Å. Future papers will investigate the physical properties of this sample.
A new method of noncontact measurement of the plane parameters

A noncontact measurement method of rotating object plane parameters were studied based on the geometrical optics principle and the computer vision technology. The method principle is that the laser, which reflects from the measured object, forms a track on the receiver with the object rotating. Then, CCD camera adopts images of the track and the plane parameters are obtained by processing the images. Mathematic model for the measurement was established from geometry optics and an experimental system for the measurement was developed. The results from the experimental system were compared with data of the eddy current sensor measuring. And the comparison shows that the measurement method is feasible.
A Very Luminous Binary Millisecond Pulsar

We report the discovery of a field binary millisecond pulsar, J0218+4232, with a period of 2.3 ms and in a 2.0 day binary orbit with a ≳0.16 M☉ companion. The new pulsar was serendipitously discovered as a steep-spectrum, highly polarized, compact radio source during imaging observations at Westerbork, and was later confirmed to be a pulsar with observations carried out with the 76 m antenna at Jodrell Bank. With a dispersion measure of 61 pc cm-3, it lies outside the electron layer in the direction l = 140°, b = -18°. At a distance of more than 5.7 kpc, it is the farthest known field millisecond pulsar and has a radio luminosity L400 comparable to that of PSR B1937+21. It appears that a significant fraction of the radio emission is not pulsed. This, together with the extremely broad pulse profile, suggests that we are looking at an aligned rotator.
Cooking a pro-veg*n social identity: the influence of vegan cooking workshops on children’s pro-veg*n social identities, attitudes, and dietary intentions

Abstract Plant-based dietary choices can help to mitigate climate change. Yet, most people still consume meat. Social identity influences dietary choices. This study tests whether shared identity, pro-veg*n norms, attitudes, and dietary intentions, can be strengthened via a vegan cooking workshop for children. Pupils (N = 155) cooked in small groups (3–6 members). Compared to pre-measures, shared identity, pro-veg*n (vegan and/or vegetarian) norms, attitudes, dietary intentions, and appreciation of vegan food increased after the vegan cooking workshop. Changed perceptions about what is important or not (injunctive norms) at school predicted changes in attitudes; increased dietary intentions were predicted by changed inferences about the behaviours of peers with whom pupils directly cooked. Jointly cooking a vegan meal thus seems an effective intervention to shape shared identity and pro-veg*n norms, and foster attitudes and dietary intentions in line with this formed pro-veg*n social identity. Therefore, cooking workshops may induce social change. Graphical Abstract
Feedback stabilization of linear systems with delayed control

Feedback controls based on the receding horizon method have proven to be a useful and easy tool in stabilizing linear ordinary differential systems. In this paper the receding horizon method is applied to linear systems with delay in the control. An open-loop optimal control which minimizes control energy subject to certain side constraints is first derived and then transformed to a closed-loop control via the receding horizon concept. The resulting feedback system is shown to be asymptotically stable under a complete controllability condition. It is also shown how the receding horizon control suggests a more general class of stabilizing feedback control laws. The control laws of this paper are perhaps the easiest way to stabilize a linear system with delay in the control.
Adaptive nonlinear diffusion algorithm for image filtering

The nonlinear anisotropic diffusive process has shown the good property of eliminating noise while preserving the accuracy of edges, and has been widely used in image processing. However, filtering depends on the threshold of the diffusion process, i.e., the cut-off contrast of edges. The threshold varies form image to image and even from region to region within an image. The problem compounds with intensity distortion and contrast variation. We have developed an adaptive diffusion scheme by applying the Central Limit Theorem to selecting the threshold. Gaussian distribution and Rayleigh distribution are used to estimate the distributions of visual objects in images. Regression under such distributions separates the distribution of the major object from other visual objects in a single peak histogram. The separation helps to automatically determine the threshold. A fast algorithm is derived for the regression process. The method has been successfully used in filtering various medical images.
Health Behaviours among Travellers Regarding Risk Compensation Following COVID-19 Vaccination in Taizhou, China

Background During the COVID-19 pandemic, public transport was restricted in many countries because of the transmission risk. According to the risk compensation theory, travellers post-COVID-19 vaccination may encounter higher risks; however, no real-world studies provide such evidence. Therefore, we conducted a survey to assess whether risk compensation would occur among travellers' health-related behaviours after COVID-19 vaccination, potentially aggravating the transmission of the virus. Materials and Methods A self-administered online survey was designed and distributed over WeChat to identify the difference in health behaviours before and after COVID-19 vaccination among travellers at a train station in Taizhou, China, from 13 February to 26 April 2022. Results A total of 602 individuals completed the questionnaire. The results revealed no statistical difference between the health behaviours reported by the vaccinated and unvaccinated groups. Participants who received the first dose of the vaccine earlier showed no statistical difference in harmful health behaviours (hand washing frequency decreased by 4.1% (P=0.145) and the duration of public transport travel increased by 3.4% (P=0.437)), but showed better protective health behaviours (mask-wearing duration increased by 24.7% (P=0.014)). Compared to those vaccinated less than three times, participants vaccinated against COVID-19 three times showed no statistical differences in harmful health behaviours mask-wearing duration decreased by 7.0% (P=0.927), their hand washing frequency decreased by 4.8% (P=0.905), and the duration of public transport travel increased by 2.5% (P=0.287). After vaccination, when compared to themselves before vaccination, participants exhibited better health behaviours (increased hand washing frequency and mask-wearing duration, and decreased duration of public transport travel) to some extent. Conclusion In conclusion, this study found no evidence of risk compensation among travellers. After being vaccinated, health behaviours partly improved among travellers.
A simplified Extended Kalman Filter for the global operational soil moisture analysis at ECMWF

A new land surface analysis system based on a simplified point‐wise Extended Kalman Filter (EKF) was implemented at the European Centre for Medium‐Range Weather Forecasts in the global operational Integrated Forecasting System (IFS) in November 2010. This system will allow consistent and optimal analyses of land surface parameters like soil moisture, surface temperatures, snow and vegetation properties. As part of the system implementation, the surface analysis structure has been revised to permit an independent and parallel computation with the upper‐air 4D‐Var analysis. The new analysis system is used for the soil moisture analysis, replacing the previous Optimal Interpolation (OI) scheme. Similar to the OI system, the simplified EKF uses 2 m air temperature and relative humidity observations from the SYNOP (land surface synoptic report) ground‐based networks to analyse soil moisture. This paper describes the new land surface analysis, its application for analysing soil moisture, and initial verification results which supported its operational implementation at ECMWF. The performance is evaluated based on a set of one‐year analysis experiments. The simplified EKF is compared to the OI, on soil moisture, 2 m temperature and relative humidity, showing a consistent improvement on screen‐level parameters and soil moisture forecasts. To demonstrate the potential of the new analysis scheme, soil moisture derived from ASCAT (Advanced Scatterometer) has been assimilated through the simplified EKF.
Soft-Tissue Anaplastic Lymphoma Kinase-Positive Anaplastic Large Cell Lymphoma in a Child Unmasked by COVID-19

Anaplastic large cell lymphoma (ALCL) is children’s most common mature T-cell neoplasm. The majority is positive for anaplastic lymphoma kinase (ALK). Initial presentation as a soft-tissue pelvic mass without nodal involvement is rare and can be easily misdiagnosed. We report a case of a 12-year-old male presenting with pain and movement restriction in the right extremity. Computed tomography (CT) scan revealed a solitary pelvic mass. Initial biopsy examination concluded rhabdomyosarcoma. After developing pediatric multisystemic inflammatory syndrome due to coronavirus disease 2019 (COVID-19), central and peripheral lymph node enlargement appeared. New cervical adenopathy and pelvic mass biopsies were performed. Immunohistochemistry concluded an ALK-positive ALCL with a small-cell pattern. The patient was treated with brentuximab-based chemotherapy and eventually improved. Differential diagnosis of pelvic masses in children and adolescents must include ALCL. An inflammatory trigger may promote the appearance of a typical nodal disease, previously absent. Attention is warranted during histopathological examination to avoid diagnostic errors.
Carbon and nitrogen abundances in F- and G-type stars

Carbon and nitrogen abundances have been obtained for a sample of 11-F- and G-type dwarfs covering a range in Fe/H abundance ratio from -0.8 to +0.3. Model atmospheres, which included the effects of convection and line blanketing, were used to calculate synthetic spectra of the CH, CN, and NH molecular bands. Effective oscillator strengths for the bands studied were found by matching synthetic spectra calculated from a model solar atmosphere with the observed solar bands. Many of the metal-poor stars, and particularly the high-velocity stars, were found to have substantial nitrogen over-deficiencies, suggesting that N is manufactured mostly in a secondary manner. The carbon-to-iron ratios were similar to the solar ratio, although there may be slight C over-deficiencies in metal-poor stars. However, the variation in C/Fe is not as marked as that found recently by Hearnshaw (1974). A comprehensive discussion of the theoretical errors is given, and some applications to Galactic evolution are noted.
Complete chloroplast genome of Daphne pseudomezereum var. koreana (Thymelaeaceae)

Abstract Daphne pseudomezereum A. Gray var. koreana (Nakai) Hamaya is a shrub distributed in high mountains in Japan and Korea and is used as a medicinal plant. The complete chloroplast genome of D. pseudomezereum var. koreana is 171,152 bp long with four subregions consisting of a large single-copy region (84,963 bp), a small single-copy region (41,725 bp), and a pair of inverted repeats (2739 bp). The genome includes 139 genes (93 protein-coding genes, eight rRNAs, and 38 tRNAs). Phylogenetic analyses show that D. pseudomezereum var. koreana is nested within the Daphne clade in the narrow sense and that it forms a distinct lineage.
Multichannel Six‐Wave Mixing with Spatial Multimode and Squeezing via Atomic Coherence

Multimode properties, based on nonlinear parametric processes, have potential research value on entanglement imaging. This paper studies the spatial and frequency multimode from dressing parametric‐amplified six‐wave mixing (PA‐SWM) process with three entangled signals. The S1 signal contains fifth‐order nonlinearity, the S2 signal contains electromagnetically induced absorption and fifth‐order nonlinearity, and the S3 signal contains Autler–Townes splitting (AT), second‐ and fifth‐order nonlinearity. The frequency multimode is attributed to dressing energy level splitting in spontaneous SWM (SSWM) process. The spatial multimode is due to frequency multimode and beam splitting via Kerr nonlinearity. In the spatial domain, it finds the optimal conditions of intensity difference squeezing (IDS) and spatial imaging along with their competitive relationship. On the one hand, the light spots with single spatial mode are contributed to the maximum IDS but not conducive to entanglement imaging; on the other hand, the light spots with multiple spatial modes are instrumental in entanglement imaging but not appropriate for the IDS. This research has potential applications in squeezed light sources for quantum metrology, and correlated imaging of spatial signals.
Multidimensional quantum well laser and temperature dependence of its threshold current

A new type of semiconductor laser is studied, in which injected carriers in the active region are quantum mechanically confined in two or three dimensions (2D or 3D). Effects of such confinements on the lasing characteristics are analyzed. Most important, the threshold current of such laser is predicted to be far less temperature sensitive than that of conventional lasers, reflecting the reduced dimensionality of electronic state. In the case of 3D‐QW laser, the temperature dependence is virtually eliminated. An experiment on 2D quantum well lasers is performed by placing a conventional laser in a strong magnetic field (30 T) and has demonstrated the predicted increase of T0 value from 144 to 313 °C.
Efficient Dynamic Time Warping Using 2nd Derivative Operator

Dynamic Time Warping based on Dynamic Programming is the one of the most widely been used to compare the similarity of two patterns. DTW algorithm has two known problems. The one is singularities. And the another problem is the accuracy of the warping path with patterns. Therefore, this paper suggest the solution for DTW algorithm to use a 2nd derivative operator. Laplacian of Gaussian is a kind of a 2nd derivative operator. Consequently, our suggestion method to apply to this operator, more efficient to solve the singularities problems and to secure a accuracy of the warping path. And the result shows a superior ability of this suggested method.
The relative positions of the OH and H$sub 2$O masers in W49N and W3(OH)

The relative positions of the OH and H$sub 2$O masers in W49N and W3(OH) have been found by simultaneously observing both masering transitions with a very- long-baseline interferometer. In both sources the OH and H$sub 2$O features are clearly separated and occupy two distinct regions of space, separated by 48,000 AU and 18,000 AU in W49N and W3(OH), respectively. The two masering regions appear unlikely to have the same source of excitation.
Hubble space telescope Goddard High-Resolution Spectrograph observation of U Geminorum during quiescence: Evidence for a slowly rotating white dwarf

We have obtained a pair of consecutive far-ultraviolet Goddard High-Resolution Spectrograph (GHRS) exposures of the Si IV region of the dwarf nova U Geminorum in early quiescence, 8 days after its return to optical quiescence when the underlying white dwarf dominates the ultraviolet light of the system. Our GHRS observation revealed a fully resolved line profile for the resonance doublet of Si IV. If it is associated with the white dwarf photosphere, then our best synthetic fits are consistent with T (sub eff) = 35,000 K-38,000 K, log g = 8, a rotational velocity of 50 to 100 km per sec, with a modestly enhanced silicon abundance (1.3-2.3 times solar) and our results suggest that at least in U Gem and perhaps in other similar dwarf novae, the missing boundary layer cannot be explained by rapid rotation of the white dwarf. However, the gamma-velocity of the system remains uncertain. If the gamma-velocity is 43 km per sec (Friend et al. 1990), then a gravitational redshift of approximately 50-60 km per sec is implied for the white dwarf. If the gamma-velocity is 84 km per sec (Wade 1981), then a gravitational redshift of only 10-30 km per sec is indicated, which may imply that either the white dwarf has a low (0.5-0.6 of Solar Mass) mass or an extended atmosphere (corona) due to the outburst heating 8 days earlier. The implications of our line-fitting results for the structure and temperature of boundary layers in cataclysmic variables are discussed.
ANALYSIS OF SYNCHRONOUS MOTOR STABILITY USING HOPF BIFURCATION

Abstract Investigation of synchronous motor stability needs the study of a set of first order nonlinear differential equations. Due to this nonlinearity, the behavior of the synchronous motor during small disturbances is understood by looking at the eigenvalues of the linearised equations. One of the most powerful methods to analyse the dynamics of a nonlinear system is the theory of Hopf Bifurcation which uses the eigenvalues of the linearised system. This paper uses the Hopf Bifurcation theorem to determine different stability patterns of a synchronous motor. As the system voltage changes, the bifurcation of different equilibrium states are examined. A test system is used to simulate the changes taking place in the stationary solution. The properties of the nonlinear periodic solution are also uncovered and the relationship between the two solutions is established.
X-ray variability of GX 339 - 4 in its very high state

GX 339-4 was observed with the large area counters (LAC) onboard Ginga in its very high state, where the X-ray intensity was about a factor of 2-3 larger than its high state and it showed very rapid variations on time scales of less than several minutes, which had not been observed earlier in the high state of this source. The X-ray energy spectrum was very soft; it consisted of a low-energy component and a high-energy tail
Frequencies of high-degree solar oscillations

Acoustic oscillations of the sun were observed at Big Bear Solar Observatory by measuring Doppler shifts at three different spatial resolutions, in order to measure the frequencies of solar p-modes at low, intermediate, and high values of spherical harmonic degree l. Distinct, sharply peaked spectral features were not identified in these data, and instead the positions of broad ridges in the l-v power diagram were measured, from which p- and f-mode frequencies were derived. A table of oscillation frequencies with l in the range of 30-132O is presented. Systematic errors in determining p-mode frequencies from ridge positions were examined for l less than 100 by comparing the measured ridge positions with frequencies obtained from the analysis of sharply peaked spectral features. This led to the identification of two types of systematic errors, which were subsequently removed from the data. Residual systematic errors in the measured frequencies are estimated for the three data sets. 5 references.
Faint star studies in the magellanic clouds. II. Field regions 9/sup 0/ northeast of the large magellanic cloud bar

Photographic photometry is reported for 16 halo field regions. These fields lie 9. /sup 0/1 northeast of the LMC bar, surrounding the old globular cluster NGC 2257. Field color-magnitude diagrams show a red horizontal branch, a subgiant branch redder than that of the cluster, and a profusion of blue stars delineating a younger main-sequence. Possible sources of the blue stars are discussed. The field is significantly younger than the cluster, showing that star formation, even in the outer regions of the LMC where the gas density is presently minimal, proceeded long after the formation of the old clusters. It appears that the major portion of stars in the LMC is of intermediate age. That this is true of a region 9 kpc from the bar is of great importance to the eventual derivation of a global history of star formation in the LMC.
