Sequential Sales of Similar Assets: The Law of One Price and Real Estate

The housing literature largely overlooks the price evolution of similar assets sold sequentially, even though such sales often occur with new residential developments. The law of one price implies no persistent price pattern for identical assets sold sequentially. Nonetheless, the auction and nonauction literatures reveal conditions leading to sales sequence effects on prices. This paper examines price evolution in the condominium market where similar units are sold sequentially in a setting with minimal consumption risk. The results indicate no pervasive sequence-price relationship for sequential sales of similar property units.
The Role of Organized Unsaturated Convective Downdrafts in the Structure and Rapid Decay of an Equatorial Disturbance

Abstract The Line Islands Experiment, conducted on and near Palmyra, Fanning and Christmas Islands during February-April 1967, produced extensive data on disturbances of the equatorial trough zone. One disturbance which passed through the heart of the data network is analyzed in detail. This disturbance intensified rapidly just east of Fanning Island during the night of 31 March–1 April, but satellite observations show that it dissipated rapidly during the daylight hours of 1 April. The convergence-divergence patterns associated with the growth and decay of the disturbance are most intense in the lowest 500 m. Data from serial rawinsonde releases on the islands, combined with research aircraft data, are presented which demonstrate that highly unsaturated downdrafts are produced, first on the convective scale and the mesoscale, and finally becoming organized over the entire 600-km extent of the system. Cumulus development is effectively suppressed in the downdraft air, only being restored after 6–12 hr by .
Electrical resistance and mechanical stress in NiCr/Cu/NiCr thin films

NiCr/Cu/NiCr film configurations are used for metallization of chip resistors. The influence of a heat treatment on the electrical resistance of these films has been investigated ex situ and in situ. This has been correlated with concentration depth profiles determined by Auger electron spectrometry. Up to 450 °C only weak interdiffusion has been found, so that distinct resistance changes occur only for films with small Cu-sublayer thicknesses. The distinction of NiCr/CuNi/NiCr resistor films with characteristic interdiffusion effects is explained on the basis of phase diagram. In comparison to copper films, the temperature dependence of the effective biaxial stress in the NiCr/Cu/NiCr film configuration shows a reduced stress relaxation due to the plastically undeformable NiCr films.
Bioturbation and manganese cycling in hemipelagic sediments

The activities of infaunal macrobenthos have major influences on the types, rates and distributions of diagenetic reactions involving manganese in relatively carbon-rich deep-sea and nearshore sediments. In some non-sulphidic hemipelagic deposits of the eastern equatorial Pacific (Panama Basin) biogenic reworking drives internal cycles of manganese, which can apparently account for up to ca. 100% of organic carbon oxidation and reduction of 02 supplied (diffusively) to the sea floor. Heterotrophic (carbon-based) manganese reduction is stimulated by simultaneous mixing of reactive organic matter and manganese oxide into suboxic-anoxic deposits. In sulphidic sediments, biogenic reworking must also enhance a lithotrophic pathway (sulphur-based) pathway of manganese reduction by promoting contact of manganese oxides and iron sulphides. Particle reworking dramatically alters the balance between aerobic and anaerobic decomposition pathways, promoting the utilization of 02 in the reoxidaton of reduced metabolites rather than direct oxidation of carbon. Irrigated burrows create microenvironments, which increase manganese reduction—oxidation and deplete Mn2+ from deeper pore waters. This may increase net Mn2+ production rates by removal of metabolites and potential co-precipitants with Mn2+. The occurrence and geometry of manganese oxide encrusted biogenic structures imply specific adaptations of infauna to manganese based microbial activity in hemipelagic sediments like the Panama Basin.
Silodosin as a medical expulsive therapy for distal ureteral stones: A systematic review and meta-analysis

Introduction: Tamsulosin is the most commonly used medical expulsive therapy (MET). However, it does not alleviate ureteral colic. It is important to develop MET that can reduce ureteral colic while maintaining a high stone clearance rate. Silodosin is an α1A adrenoceptor with high affinity and selectivity for the distal ureter, which may reduce ureteral colic and enable stone expulsion for distal ureteral stones. Therefore, we performed this systematic review and meta-analysis to evaluate the efficacy of silodosin as MET and its role in reducing ureteral colic among patients with distal ureteral stones. Materials and Methods: This research was conducted in accordance with the Cochrane Handbook for Systematic Review and Intervention, in adherence with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses, and was registered in the International Prospective Register of Systematic Reviews (PROSPERO CRD42021249003). A comprehensive literature search was performed in several databases including Medline, EMBASE, and Scopus up to July 2021 for randomized trials comparing silodosin with placebo for MET. RevMan 5.4 was used for data analysis. Results: A total of six randomized controlled trials were included in this analysis with a total of 907 patients. Our analysis revealed that the patients who received silodosin had significantly higher stone expulsion rate (SER) (odds ratio [OR] 3.33, 95% confidence interval [CI] 2.34, 4.76, P < 0.01), significantly shorter stone expulsion time (SET) (mean difference −3.79, 95% CI −4.51, −3.06, P < 0.01), and lower analgesic use (OR 0.4, 95% CI 0.23, 0.69, P < 0.01) compared to the group receiving placebo. Conclusion: Silodosin showed significantly higher SER, lower SET and lower analgesic use in patients with distal ureteral stones as compared to a placebo.

HYPERSPECTRAL IMAGE ANALYSIS USING A CUSTOM SPECTRAL CONVOLUTION NEURAL NETWORK

: In recent time, the most applied classification method for hyperspectral images is based on the supervised deep learning approach. The hyperspectral images require special handling while it consists of hundreds of bands / channels. In this article, the experiments are conducted using one of the widespread deep learning models, Convolutional Neural Networks (CNNs), specifically, Csutom Spectral CNN architecture (CSCNN). The introduced network is based on the data reduction and data normalization. It firstly ommits the unnecessary data channels and retains the meaningful ones. Then, it passes the remaining data through the CNN layers (convolutional, rectified linear unit, fully connected, dropout,…etc) until reaches the classification layer. The experiments are applied on four benchmarcks [hyperspectral datasets], namely, Salinas-A, Kenndy Space Center (KSC), Indian Pines (IP), and Pavia University (Pavia-U). The proposed model achieved an overall accuracy more than 99.50 %. In last, a comparison versus the state of the art is also introduced.
Role of the substrate in the electrical transport characteristics of focused ion beam fabricated nanogap electrode

Precise metallic nanogap structure is fabricated on a glass substrate by using a 30 keV focused Ga ion beam. While investigating the I-V behavior of the nanogap structure, tunneling through the substrate has been found to play a vital role in the electrical transportation process. Substrate breakdown occurs at a certain applied voltage and a metal vapor state is initiated through intense heat generation at the nanogap region. The experimental observation confirms the role of the substrate in the explosion process. Metallic spherical particles are formed during cooling/condensation of the metal vapors or splashing of the liquid droplets showing a wide distribution of size from few tens of nanometers to few microns.
A 6 b 1.3 GSample/s A/D converter in 0.35 μm CMOS

A 6-b Nyquist A/D converter (ADC) that converts at 1.3 GHz is reported. Using array averaging and a wideband track-and-hold, a 6-b flash ADC achieves better than 5.5 effective bits for input frequencies up to 630 MHz at 1 Gsample/s, and five effective bits for 650-MHz input at 1.3 Gsample/s. Peak INL and DNL are less than 0.35 LSB and 0.2 LSB, respectively. This ADC consumes about 500 mW from 3.3 V at 1 Gsample/s. The chip occupies 0.8-mm active area, fabricated in 0.35m CMOS.
Characterization of porcine eyes based on autofluorescence lifetime imaging

Multiphoton microscopy is a non-invasive imaging technique with ideal characteristics for biological applications. In this study, we propose to characterize three major structures of the porcine eye, the cornea, crystalline lens, and retina using two-photon excitation fluorescence lifetime imaging microscopy (2PE-FLIM). Samples were imaged using a laser-scanning microscope, consisting of a broadband sub-15 femtosecond (fs) near-infrared laser. Signal detection was performed using a 16-channel photomultiplier tube (PMT) detector (PML-16PMT). Therefore, spectral analysis of the fluorescence lifetime data was possible. To ensure a correct spectral analysis of the autofluorescence lifetime data, the spectra of the individual endogenous fluorophores were acquired with the 16-channel PMT and with a spectrometer. All experiments were performed within 12h of the porcine eye enucleation. We were able to image the cornea, crystalline lens, and retina at multiple depths. Discrimination of each structure based on their autofluorescence intensity and lifetimes was possible. Furthermore, discrimination between different layers of the same structure was also possible. To the best of our knowledge, this was the first time that 2PE-FLIM was used for porcine lens imaging and layer discrimination. With this study we further demonstrated the feasibility of 2PE-FLIM to image and differentiate three of the main components of the eye and its potential as an ophthalmologic technique.
Discovery of a protostar in the Large Magellanic Cloud

A near infrared search of the H II region/molecular cloud complex N159 in the Large Magellanic Cloud has revealed a very red (H-K = 2.1, K-L-prime = 2.7) compact object. The location, brightness, color and 2.1-2.4 micron spectrum of this source suggest that it is very young, and similar to the galactic infrared protostars. This is the first identification of an infrared protostar in an external galaxy. Its discovery provides direct evidence of current star formation in the Large Magellanic Cloud, and suggests that regions of star formation in external galaxies will appear similar to those in the Milky Way.
Engineering chemically abrupt high-k metal oxide∕silicon interfaces using an oxygen-gettering metal overlayer

High-k metal oxide gate dielectrics may be required to extend Moore’s law of semiconductor device density scaling into the future. However, growth of a thin SiO2-containing interface layer is almost unavoidable during the deposition of metal oxide films onto Si substrates. This limits the scaling benefits of incorporating high-k dielectrics in future transistors. A promising approach, in which oxygen-gettering metal overlayers are used to engineer the thickness of the SiO2-based interface layer between metal oxide and Si substrate after deposition of the metal oxide layer, is reported. Using a Ti overlayer with high solubility for oxygen on ZrO2 or HfO2 dielectrics, the effective removal of the low-k interface layer at 300K has been confirmed by electron microscopy and spectroscopy techniques. Significant enhancement of the gate capacitance density, while retaining low leakage current densities, has also been demonstrated for these interface-engineered high-k gate stacks.
Implementation of multiview calibration system for an effective 3D display

In this paper, we proposed multiview calibration system for an effective 3D display. This system can obtain 4-view image from multiview camera system. Also it can be rectify lens and camera distortion, an error of bright and color, and it can be calibrate distortion of geometry. We proposed the signal processing skill to calibrate the camera distortions which are able to take place from the acquired multiview images. The discordance of the brightness and the colors are calibrated the color transform by extracting the feature point, correspondence point. In addition, the difference of brightness is calibrated by using the differential map of brightness from each camera image. A spherical lens distortion is corrected by extracting the pattern of the multiview camera images. Finally the camera error and size among the multiview cameras is calibrated by removing the distortion. Accordingly, this proposed rectification & calibration system enable to effective 3D display and acquire natural multiview 3D image.
A detailed analysis of film-cooling physics: Part IV -- Compound-angle injection with shaped holes

The flow physics of film cooling with compound-angle shaped holes is documented for realistic gas turbine parameters. For the first time in the open literature, the combined effects of compound-angle injection and hole shaping are isolated and the dominant mechanisms are examined. Results provide valuable insight into the flowfield of this class of film-cooling jets. Computational and experimental results are presented for a row of holes injected at 35 deg on a flat plate with three distinct geometric configurations: (1) streamwise injected cylindrical holes (reference case); (2) 15 deg forward-diffused holes injected at a 60 deg compound angle; and (3) 12 deg laterally diffused holes injected at a 45 deg compound angle. Detailed field and surface data, including adiabatic effectiveness (η) and heat transfer coefficient (h), of the two compound-angle shaped holes are provided and compared to: (i) the reference streamwise cylindrical case; (ii) results from Part II detailing the compound-angle flowfield for cylindrical holes; (iii) results of Part III detailing the streamwise injected shaped-hole flowfield; and (iv) experimental data. The 60 deg compound-angle forward-diffused holes provided excellent lateral coolant distribution, but suffered from crossflow ingestion at the film-hole exit plane. The 45 deg compound-angle lateral-diffused hole had much steeper lateral effectiveness variations. A previously documented and validated computational methodology was utilized. Computations were performed using a multiblock, unstructured-adaptive grid, fully implicit pressure-correction Navier-Stokes code with multigrid and underrelaxation type convergence accelerators. All simulations had fixed length-to-diameter ratio of 4.0, pitch-to-diameter ratio of 3.0, nominal density ratio of 1.55 and film-hole Reynolds number of 17,350, which allowed isolation of the combined effects of compound-angle injection and hole shaping for nominal blowing ratios of 1.25 and 1.88. The results demonstrate the ability of the prescribed computational methodology to predict accurately the complex flowfield associated with compound-angle shaped-hole film-cooling jets.
Interface-capturing methods for two-phase flows : An overview and recent developments

Two-phase flows are of great interest in natural and industrial applications such as rain formation (Shaw 2003), breaking waves (Melville 1996), spray atomization (Sirignano 1999) and bubbly flows (Sato et al. 1981; Clift et al. 2005). The purpose of this report is to survey the available interface-capturing methods for two-phase flows and to present them in a consistent fashion to facilitate comparison. We highlight the outstanding issues and challenges in two-phase flow modeling and discuss the relative advantages and disadvantages of the various interface-capturing methodologies. The literature on these methods continues to grow in an almost intractable manner. Hence, we will focus on interface-capturing methodologies that are currently in use and being actively developed by the two-phase community. Moreover, within different categories, we will only chronologically review milestones while alluding to the state of the art or most promising research directions. We apologize beforehand if we have overseen major contributions. Hopefully, this work can serve as an update/overview to veterans of the two-phase community while also guiding new researchers of the field in choosing a two-phase flow solver best suited for their applications. All conclusions and recommendations in this work are qualitative; quantitative comparison between different two-phase flow categories or methods would be complementary to this work.
Sum Rules in the Dispersion Theory of Nuclear Reactions

In the first five sections the dispersion theory is developed with an internal region $V$ whose boundary $S$ is quite close to the nuclear surface. Two types of quantities then occur: those like the derivative matrix $R$, which connect the values and derivatives of the wave function at $S$, and those like the collision matrix $U$ which give the asymptotic behavior of the wave function. These latter are, of course, independent of the position of $S$. Because of the proximity of $S$ to the nuclear surface, the wave function in the closed channels and its derivative remain appreciable at $S$. They may, however, be eliminated from the formalism, and this is done in Sec. II, leading to a reduced $R$ which connects the values and derivatives of the wave function in the open channels only. In the next section this reduced $R$ is used to obtain expressions for the $S$-independent quantities, in particular, for the collision matrix. These expressions are given more explicit, but approximate form in Sec. IV. The development shows that the quantity, which in the usual formulas for the cross sections is interpreted as the nuclear radius, need not be equal to this at all, but is the distance at which two opposite effects compensate. The fifth section gives exact expressions for the poles and residues of some $S$-independent quantities, which are then compared with the poles and residues of the approximate expressions of the previous chapter. In this way criteria are derived for the accuracy of these approximate expressions.
On the resonant generation of large-amplitude internal solitary and solitary-like waves

In this paper we discuss numerical simulations of the generation of large-amplitude solitary waves in a continuously stratified fluid by flow over isolated topography. We employ the fully nonlinear theory for internal solitary waves to classify the numerical results for mode-1 waves and compare with two classes of approximate theories, weakly nonlinear theory leading to the Korteweg–deVries and Gardner equations and conjugate flow theory which makes no approximation with respect to nonlinearity, but neglects dispersion entirely. We find that both weakly nonlinear theories have a limited range of applicability. In contrast, the conjugate flow theory predicts the nature of the limiting upstream propagating response (a dissipationless bore), successfully describes the bore's vertical structure, and gives a value of the inflow speed, $c_j$, above which no upstream propagating response is possible. The numerical experiments demonstrate the existence of a class of large-amplitude response structures that are generated and trapped over the topography when the inflow speed exceeds $c_j$. While similar in structure to fully nonlinear solitary waves, these trapped disturbances can induce isopycnal displacements more than 100% larger than those induced by the limiting solitary wave while remaining laminar. We develop a theory to describe the vertical structure at the crest of these trapped disturbances and describe its range of validity. Finally, we turn to the generation of mode-2 solitary-like waves. Mode-2 waves cannot be truly solitary owing to the existence of a small mode-1 tail that radiates energy downstream from the wave. We demonstrate that, for stratifications dominated by a single pycnocline, mode-2 wave dissipation is dominated by wave breaking as opposed to mode-1 wave radiation. We propose a phenomenological criterion based on weakly nonlinear theory to test whether mode-2 wave generation is to be expected for a given stratification.
Simulations of the extreme adaptive optics system for EPICS

EPICS is a project for a high contrast imaging instrument dedicated to direct imaging of exoplanets with the European Extremely Large Telescope. Its conceptual design study phase has finished at the early 2010, and we show here its end-to-end extreme adaptive optics simulation results. The simulations have been made using conventional, well-known but numerically intensive computation techniques (full Fourier diffraction model of a WFS and wavefront reconstruction with matrix-vector-multiplication). Many error sources important for XAO are considered: chromaticity effects, M1 segment mis-figure, pupil rotation, WFS misregistration, telescope jitter and spiders. The results confirm that a raw contrast of 10-5 is reached at 20 mas, and 10-7-10-6 at 200-500 mas. This is in agreement with our analytic estimations and EPICS top-level requirements.
Visualization of quality parameters for classification of spectra in shooting crimes

X‐ray emission spectra from gunshot residues (GSR) are evaluated in order to assign them to a certain ammunition brand. Classification is based on regularized discriminant analysis (RDA) providing class information as well as additional parameters for judging the quality of an assignment. For visualization of measures such as the posterior probability, distance to centre or inverse Mahalanobis distances different approaches are explored and their common interpretation is evaluated.

Parametric Study of Vortices Shed from Airfoil Vortex Generators

Extensive parametric study of vortices shed from the tips of airfoil vortex generators has been conducted to determine the dependence of initial vortex circulation and peak vorticity on elements of airfoil geometry and impinging-flow conditions. The vortex generators were symmetric airfoils examined in subsonic airflow on the surface of a straight pipe. The circulation and peak-vorticity data were derived from cross-plane velocity measurements acquired with a seven-hole probe one chord length downstream of the airfoil-trailing-edge-tip location. Circulation and peak vorticity are observed to be proportional to the freestream Mach number, the angle of attack, and the span-to-boundary-layer-thickness ratio
