Bioinformatic Analysis of PTTG Family and Prognosis and Immune Cell Infiltration in Gastric Cancer

Gastric cancer is the sixth highest incidence rate in the world. Although treatment has made progress, the prospect of gastric cancer patients is bleak. Difficulties and future prospects of immunotherapy in cancer treatment. Adaptive cell therapy, cancer vaccines, gene therapy, and monoclonal antibody therapy have all been used in gastric cancer with some initial success. PTTGs (pituitary tumor-transforming genes) have been proven to be closely related to the prognosis of many malignant tumors. However, the prognosis and immune cell infiltration of gastric adenocarcinoma (STAD) remain unclear. We retrieved multiple databases to understand the possible activity of PTTGs and their expression in gastric cancer, as well as their relationship with clinical data, overall survival rate, first progression, and survival rate after progression. PTTGs are overexpressed in STAD tumor tissues. Many clinical variables are closely related to PTTGs. In addition, PTTG was associated with overall survival independent of disease. In addition, the expression of PTTG1/2 was positively correlated with the molecular status of the immune checkpoint and negatively correlated with the infiltration of various immune cells. Data research shows that PTTG and STAD are closely related. This paved the way for future research, revealed the complex pathophysiology of gastric cancer, and introduced an effective new treatment.
RESEARCH ARTICLE Multiple scattering of elastic waves: a numerical method for computing the effective wavenumbers

Elastic wave propagation is studied in a heterogeneous 2-D medium consisting of an elastic matrix containing randomly distributed circular elastic inclusions. The aim of this study is to determine the effective wavenumbers when the incident wavelength is similar to the radius of the inclusions. A purely numerical methodology is presented, with which the limitations usually associated with low scatterer concentrations can be avoided. The elastodynamic equations are integrated by a fourth-order time-domain numerical scheme. An immersed interface method is used to accurately discretize the interfaces on a Cartesian grid. The effective field is extracted from the simulated data, and signal-processing tools are used to obtain the complex effective wavenumbers. The numerical reference solution thus-obtained can be used to check the validity of multiple scattering analytical models. The method is applied to the case of concrete. A parametric study is performed on longitudinal and transverse incident plane waves at various scatterers concentrations. The phase velocities and attenuations determined numerically are compared with predictions obtained with multiple scattering models, such as the Independent Scattering Approximation model, the Waterman-Truell model, and the more recent Linton-Martin-Conoir-Norris model.
On the formation and structure of downdrafts in cumulus clouds

Abstract With use of the model of the steady-state entraining cumulus draft, it is possible to describe the formation and structure of the downdraft observed at the down-shear edge of an oceanic trade-cumulus cloud. The observations are airplane traverses made at several levels giving the temperature, humidity, and vertical draft structure in cloud and environment, and a nearby pilot-balloon run. It is found that this downdraft must be mixing primarily with the updraft; that it gains its negative buoyancy mainly from evaporation; and that it is permitted to go through a life cycle of formation, strengthening, and decay which is closely dependent upon that of the updraft.
Families of Minimax Estimators of the Mean of a Multivariate Normal Distribution

Abstract : Ever since Charles Stein proved that for squared error loss the sample mean X of a multivariate normal distribution is an inadmissible estimator of its expectation theta, statisticians have searched for uniformly better (minimax) estimators with good properties. Stein has found an unbiased estimator for the risk function of an arbitrary estimator of theta, when the dispersion matrix sigma of X is known. The authors extend this very useful result to include unbiased estimates of the risk function in two cases where sigma must be estimated. This formula is used in the main theorem, to obtain more general conditions than previously published. Finally it is proven that the limited translation estimators, which are not orthogonally invariant, of Efron and Morris are minimax.
Tilt and alpha best of major flare-producing active regions

We surveyed 86 active regions in the years from 1996 to 2002 in the 23rd solar cycle that produced more than three major flares. We studied the systematic tilt angle with respect to the solar equator and the force-free parameter $\alpha_{\rm best}$ of the magnetic field of the active regions, and we obtained the following results. (1) Only 46 (54%) of the active regions follow Joy's law. (2) 43 (50%) active regions obey the hemispheric helicity rule. (3) 56 (65%) have the same sign for the tilt and the $\alpha_{\rm best}$, and the tilt and the $\alpha_{\rm best}$ of all 86 regions are positively correlated. (4) 33 (60%) of the 55 active regions which have an $\beta\gamma\delta$ magnetic configuration show the same sign for the tilt and $\alpha_{\rm best}$. It is commonly believed that the sign of the tilt and $\alpha_{\rm best}$ obtained in the photosphere can describe the sign of the twist and writhe of the flux tube rising from the convection zone. Therefore, the results above appear to support the kink hypothesis for active regions that the sign of the twist and writhe should be the same where a kink instability has developed (Linton et al. [CITE]).

The effects of the solid inner core and nonhydrostatic structure on the Earth's forced nutations and Earth tides

Recent highly accurate nutation results from very long baseline interferometry (VLBI) disagree with the 1980 International Astronomical Union (IAU) nutation model by about 2 milliarcseconds (mas). Most of the discrepancy is at the retrograde annual frequency, and it has been interpreted as being due to a nonhydrostatic core-mantle boundary (CMB) ellipticity [Gwinn et al., 1986]. The ellipticity affects the eigenfrequency of the free core nutation (FCN) normal mode, predominantly a relative rotation about an equatorial axis between the fluid outer core (OC) and the solid mantle. This interpretation in terms of a nonhydrostatic CMB shape is consistent with inferences from diurnal tidal gravity measurements [Levine et al., 1986; Neuberg et al., 1987]. The theory that this interpretation is based on assumes that the inner core (IC)is a fluid. Furthermore, the Earth is presumed to be everywhere hydrostatically prestressed, and so it is inconsistent to use results from this theory to infer information about nonhydrostatic structure. In this paper, we extend the theoretical results to include the effects of a solid IC, and of nonhydrostatic structure. The presence of the IC is responsible for a new, nearly diurnal, prograde normal mode (for a hydrostatically prestressed Earth, the frequency is (1 – 1/471) cycles per day) that involves a relative rotation between the IC and OC about an equatorial axis. We call this newly modeled normal mode the free inner core nutation (FICN). The FICN causes a perturbation in the prograde semiannual nutation amplitude of close to 0.2 mas, but the contribution to the retrograde annual nutation is only 0.003 mas, not enough to explain the VLBI discrepancy. Its effects on the diurnal Earth tide are negligible. Nonhydrostatic structure affects the eigenfrequency of this mode and causes the nutation and Earth tide amplitudes to depend on IC-OC boundary, CMB, and outer surface topography at all spatial scales. The dependence, though, falls off as the (l - 1)th power of the ratio of the IC radius divided by the OC radius, for the simplified case of a homogeneous, rigid IC and mantle, and homogeneous, incompressible OC (l, here, is the angular order in the spherical harmonic expansion of the boundary shape). For small l, nonhydrostatic effects on the FICN are of the same order as hydrostatic effects for this specialized case. Neither the IC nor the nonhydrostatic terms significantly affect the conclusions about the values of the CMB ellipticity.
Finding and estimating the number of repetition-free Boolean functions over the elementary basis in the form of a convergent series

Abstract We obtain a representation of the number Kn of repetition-free Boolean functions of n variables over the elementary basis {&, ∨,¯} in the form of a convergent exponential power series. This representation is the simplest representation among a number of similar formulas containing different combinatorial numbers. The obtained result gives a possibility to find the asymptotics of Kn .
Bonding origin of optical contrast in phase-change memory materials

The large optical contrast between crystalline and amorphous phases of phase change memory materials is shown to arise from a large difference in the optical matrix elements. These are enhanced in the crystal by aligned rows of resonantly bonded $p$ orbitals. Amorphous phases have normal-sized matrix elements due to an absence of this order, irrespective of coordination number. This is a more general description of local order differences between the crystalline and amorphous phases, which applies even when coordinations in the amorphous phases exceed the $8\ensuremath{-}\text{N}$ value.
Advanced 3D imaging lidar concepts for long range sensing

Recent developments in 3D imaging lidar are presented. Long range 3D imaging using photon counting is now a possibility, offering a low-cost approach to integrated remote sensing with step changing advantages in size, weight and power compared to conventional analogue active imaging technology. We report results using a Geiger-mode array for time-of-flight, single photon counting lidar for depth profiling and determination of the shape and size of tree canopies and distributed surface reflections at a range of 9km, with 4μJ pulses with a frame rate of 100kHz using a low-cost fibre laser operating at a wavelength of λ=1.5 μm. The range resolution is less than 4cm providing very high depth resolution for target identification. This specification opens up several additional functionalities for advanced lidar, for example: absolute rangefinding and depth profiling for long range identification, optical communications, turbulence sensing and time-of-flight spectroscopy. Future concepts for 3D time-of-flight polarimetric and multispectral imaging lidar, with optical communications in a single integrated system are also proposed.

The presented method considers NSDFB and gradient from gray-level value to recognize directionality of structure in the image. Second level of classication is needed due to the high complexity of the titanium alloys structure. During the segmentation algorithm takes into account the interaction between objects.
Water-vapor effect on the electrical conductivity of a single-walled carbon nanotube mat

In this paper we report the influence of the water vapor on the electrical resistance of a single-walled carbon nanotube mat ~SWNTm! Our results show that the sample exhibits a crossover from decreasing to increasing conductance versus water concentration in the surrounding atmosphere. We suggest that the water molecules act as a donor doping the SWNTm which has p-type semiconductor character in the outgassed state. The time dependence of the SWNTm resistance after exposition to humid atmosphere is explained as an abnormal diffusion phenomenon.
Solving the Stein Equation in compound poisson approximation

The accuracy of compound Poisson approximation can be estimated using Stein's method in terms of quantities similar to those which must be calculated for Poisson approximation. However, the solutions of the relevant Stein equation may, in general, grow exponentially fast with the mean number of ‘clumps’, leading to many applications in which the bounds are of little use. In this paper, we introduce a method for circumventing this difficulty. We establish good bounds for those solutions of the Stein equation which are needed to measure the accuracy of approximation with respect to Kolmogorov distance, but only in a restricted range of the argument. The restriction on the range is then compensated by a truncation argument. Examples are given to show that the method clearly outperforms its competitors, as soon as the mean number of clumps is even moderately large.
Investigation of multiwalled carbon nanotube interconnection geometry and electrical characteristics of an CNT-filled aluminum microgap1

In recent years a very large amount of data has been collected regarding devices formed by multiwalled carbon nanotubes (MWCNTs) in polymer matrix as well as single nanotubes. Conversely, very little investigation exists of nanotube networks composed of a small number of MWCNTs. A detailed investigation of the long time stability, adhesion to the surface, and topological structure of the interconnections between MWCNTs is reported here. Three different microscopy techniques, focused ion beam (FIB), scanning electron microscope (SEM), and atomic force microscope (AFM), were used to investigate the interconnection of MWCNTs deposited by electrophoresis on a thermally oxidized silicon wafer with aluminum microgap structures. SEM, AFM, and FIB imaging revealed an interesting interconnection morphology between the drop casted MWCNTs. In particular it was found that in some cases the MWCNTs were connected to each other in a geometry similar to a twisted structure. Furthermore a good stability of the sample in t.
Cosmological constraints on scalar field dark matter

This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole universe, plus a cosmological constant term. By using a compilation of 51 [Formula: see text] data and 1048 Supernovae data from Panteon, a mass range for the scalar field was obtained, [Formula: see text]eV, in good agreement with light mass axion particles. Also, we have obtained [Formula: see text], and the present dark matter density parameter [Formula: see text] at [Formula: see text] confidence level. These results are in good agreement to standard model of cosmology, showing that SFDM model is viable in describing the dark matter content of the universe.
Diffractive intermediate layer enables broadband light trapping for high efficiency ultrathin c-Si tandem cells

Light management through the intermediate reflector in the tandem cell configuration is of great practical importance for achieving high stable efficiency and also low cost production. So far, however, the intermediate reflectors employed currently are mainly focused on the light absorption enhancement of the top cell. Here, we present a diffractive intermediate layer that allows for light trapping over a broadband wavelength for the ultrathin c-Si tandem solar cell. Compared with the standard intermediate reflector, this nanoscale architectural intermediate layer results in a 35% and 21% remarkable enhancement of the light absorption in the top (400–800 nm) and bottom (800–1100 nm) cells simultaneously, and ultrathin c-Si tandem cells with impressive conversion efficiency of 13.3% are made on the glass substrate.

This study aims to describe a new influence of integrity and achievement motivation on organizational commitment and employee performance at the Directorate General of Customs and Excise of the East Java Regional Office. The study population was 1,168 non-structural position employees. Using the formula for SEM provisions, the number of samples was 300 respondents. The sampling method used in this study was proportional random sampling. The research design uses an explanatory approach. This study used the Likert scale and data analysis techniques using SEM with the AMOS software for variable measurements. The results showed that integrity and achievement motivation positively and significantly affected organizational commitment. Integrity has a positive and significant effect on employee performance, whereas the influence of achievement motivation is significant. Furthermore, organizational commitment has a positive and significant effect on employee performance. Organizational commitment is the variable that has the greatest impact on improving employee performance. The effect of integrity, achievement motivation, and organizational commitment on the performance of employees of the Regional Office of the Directorate General of Customs and Excise East Java I was 50.2%.
A New Ontology for Restaurant Review Sentiment Analysis

Understanding the aspects of a restaurant that contribute to people's sentiment is crucial for restaurant owners and marketers to improve customer experiences. A sentiment ontology for restaurant review sentiment analysis was proposed in this study. The proposed ontology identified six aspects of a restaurant evaluation: food, service, ambience, cleanliness, location, and price, based on 1,000 annotated Yelp data. Applying the proposed ontology in the annotated Yelp data showed that it helped improve the sentiment analysis accuracy by 11.2% on average. We believe that this study provides insights into the key factors that contribute to restaurant review sentiments.
Iterates of Bernstein polynomials.

uniformly on I. (Cf., Lorentz [2] for this and other properties of the Bernstein polynomials used here.) Let Bn(f) denote the (polynomial) function defined by (1.1), then for k > 1, Bi(f; x) = Bn(Bi ~(f); x) defines, by mathematical induction, a sequence of iterates of the Bernstein polynomials. Our purpose is to study the convergence behavior of this sequence as k—^oo^ both in the case that k is independent of n and when it is a nonconstant function of n. We show in §2 that Bi(f;x) converges (uniformly) for fixed n, to the line segment joining (0,/(0)) to (1,/(1)), and in § 3 that the sequence Bi(x; x) with appropriate assumptions on g(n), also converges, for each s = 0,1, 2, to a polynomial of degree s whose coefficients we determine explicitly. Finally, in § 4 arbitrary iterates are defined as a natural generalization of the positive integral iterates. When (1.1) is rewritten in conventional polynomial form, it becomes
Natural convection in a mushy layer

Governing equations for a mushy layer are analysed in the asymptotic regime Rm [Gt ] 1, where Rm is an appropriately defined Rayleigh number. A model is proposed in which there is downward flow everywhere in the mushy layer except in and near localized chimneys, which are characterized by having zero solid fraction. Upward, convective flow within the chimneys is driven by compositional buoyancy. The radius of each chimney is determined locally by thermal balances within a boundary layer that surrounds it. Simple solutions are derived to determine the structure of the mushy layer away from the immediate vicinity of chimneys in order to demonstrate the gross effects of convection upon the solidification within the layer.
Monopole antenna arrays for optical trapping, spectroscopy, and sensing

We introduce a nanoplasmonic platform merging multiple modalities for optical trapping, nanospectroscopy, and biosensing applications. Our platform is based on surface plasmon polariton driven monopole antenna arrays combining complementary strengths of localized and extended surface plasmons. Tailoring of spectrally narrow resonances lead to large index sensitivities (S∼675 nm/RIU) with record high figure of merits (FOM∼112.5). These monopole antennas supporting strong light localization with easily accessible near-field enhanced hotspots are suitable for vibrational nanospectroscopy and optical trapping. Strong optical forces (350 pN/W/μm2) are shown at these hotspots enabling directional control with incident light polarization.
Nomenclature and generation of three-periodic nets: the vector method

Three-periodic nets are connected graphs which permit embeddings having a threefold periodicity. To many crystal structures such nets can be meaningfully assigned and used to express the topology of the structures. It is shown that such a net can be fully characterized by a finite graph in which the edges are labelled in a suitable way. The reversal of the process of assigning a labelled finite graph to a given net can be used to generate nets of real and hypothetical crystal structures in a systematic fashion.
Surface acoustic wave propagation in aluminum nitride-unpolished freestanding diamond structures

High-quality surface acoustic wave (SAW) filters based on aluminum nitride (AlN)/diamond layered structures were prepared using the nucleation side of polycrystalline chemical vapor deposition (CVD) diamond, removed from a silicon substrate by wet etching. Highly oriented AlN thin films with optimized piezoelectric properties and with various thicknesses were sputtered onto the nucleation side of freestanding diamond. The effect of AlN thickness on the SAW phase velocity, the coupling coefficient, and the device characteristics were investigated. Experimental results show that the Rayleigh wave and the higher modes are generated. These results agree well with calculated dispersion curves and demonstrate that a high electromechanical coupling coefficient together with a high phase velocity can be obtained by using the nucleation side of freestanding CVD diamond layer.
