description: Highly excited Rydberg states of excitons in Cu$_2$O semiconductors provide a promising approach to explore and control strong particle interactions in a solid-state environment. A major obstacle has been the substantial absorption background that stems from exciton-phonon coupling and lies under the Rydberg excitation spectrum, weakening the effects of exciton interactions. Here, we demonstrate that two-photon excitation of Rydberg excitons under conditions of electromagnetically induced transparency (EIT) can be used to control this background. Based on a microscopic theory that describes the known single-photon absorption spectrum, we analyze the conditions under which two-photon EIT permits separating the optical Rydberg excitation from the phonon-induced absorption background, and even suppressing it entirely. Our findings thereby pave the way for the exploitation of Rydberg blockade with Cu$_2$O excitons in nonlinear optics and other applications.

description: This article examines technical efficiency of the Chinese grain sector using the framework of stochastic production frontier. The results reveal that: the marginal products of labor and fertilizer are much smaller than that of land; human capital and farm-level specialization have positive effect on efficiency, land fragmentation is detrimental to efficiency, and elder farmers are as efficient as younger farmers. We also examine the effects of size, mechanization and geographic location. Simulation results show that significant output gains can be obtained by eliminating land fragmentation, improving rural education and promoting specialization and mechanization.

description: Dielectric disk accelerating (DDA) structures are being studied as an alternative to conventional disk-loaded copper structures. This paper investigates numerically an efficient X-band DDA structure operating at a higher order mode of TM02-π. This accelerating structure consists of dielectric disks with irises arranged periodically in a metallic enclosure. Through optimizations, the RF power loss on the metallic wall can be significantly reduced, resulting in an extremely high quality factor Q_0=111064 and a very high shunt impedance R_shunt=605 MΩ/m. The RF-to-beam power efficiency reaches 46.6% which is significantly higher than previously-reported CLIC-G structures with an efficiency of only 28.5%. The optimum geometry of the regular and the end cells is described in detail. Due to the wide bandwidth from the dispersion relation of the accelerating mode, the DDA structure is allowed to have a maximum number of 73 regular cells with a frequency separation of 1.0 MHz, which is superior to that of conventional RF accelerating structures. In addition, the DDA structure is found to have a short-range transverse wakefield lower than that of the CLIC-G structure.

description: The dependence of the critical current density Jc on hydrostatic pressure to 0.6 GPa is determined for a single 25-degree [001]-tilt grain boundary in a bicrystalline ring of nearly optimally doped melt-textured YBa2Cu3Ox. Jc is found to increase rapidly under pressure at +20 %/GPa. A new diagnostic method is introduced (pressure-induced Jc relaxation) which reveals a sizeable concentration of vacant oxygen sites in the grain boundary region. Completely filling such sites with oxygen anions should lead to significant enhancements in Jc.

description: The demand for advanced materials has driven innovation in titanium alloy design, particularly in the aerospace, automotive, and biomedical sectors. Additive manufacturing (AM) enables the construction of multi-material structures, offering potential improvements in mechanical properties such as wear resistance and high temperature capabilities, thus extending the service life of components such as Ti6Al4V. Directed energy deposition (DED)-based metal AM was used to manufacture radial multi-material structures with a Ti6Al4V (Ti64) core and a Ti6Al4V-5 wt.% B4C composite outer layer. X-ray diffraction analysis and microstructural observation suggest that distinct B4C particles are strongly bonded to the Ti6Al4V matrix. The addition of B4C increased the average hardness from 313 HV for Ti6Al4V to 538 HV for the composites. The addition of 5 wt.% B4C in Ti6Al4V increased the average compressive yield strength (YS) to 1440 MPa from 972 MPa for the control Ti6Al4V, i.e., ~50% increase without any significant change in the elastic modulus. The radial multi-material structures did not change the compressive modulus compared to Ti6Al4V but displayed an increase in the average compressive YS to 1422 MPa, i.e., ~45% higher than Ti6Al4V. Microstructural characterization revealed a smooth transition from the Ti6Al4V at the core to the Ti64-B4C composite outer layer. No interfacial failure was observed during compressive deformation, indicating a strong metallurgical bonding during multi-material radial composite processing. Our results
description: demonstrated that a significant improvement in mechanical properties can be achieved in one AM build operation through designing and processing innovative multi-material structures using DED-based metal AM.
Self-Heating Effect Alleviation for post-Moore Era Channel Materials

Subjects: Electrical engineering not elsewhere classified

description: As the miniaturization of the transistors in integrated circuits approaches the atomic scale limit, novel materials with exceptional performance are desired. Moreover, to conduct enough current with an ultrathin and small-scale body, high drain current density is preferably required. Nevertheless, devices may suffer seriously from self-heating effect (SHE) with high drain bias and current if the generated heat cannot be dissipated efficiently. In this thesis, we introduce two material systems and several techniques to accomplish the demand without SHE. Tellurium, as a van der Waals material composed by atomic helical chains, is able to realize its one-dimensional structure. We illustrate that the cross-sectional current density of 150 MA/cm2 is achieved through boron nitride nanotube (BNNT) encapsulation without SHE due to the superior thermal conductivity of BN. With the nanotube encapsulation technique applied, one-dimensional tellurium nanowire transistors with diameter down to 2 nm are realized as well, and single tellurium atomic chain is isolated. Furthermore, atomic-layer-deposited indium oxide (In2O3) as thin-film transistors exhibit even better current carrying capacity. Through co-optimization of their electrical and thermal performance, drain current up to 4.3 mA/μm is achieved with a 1.9-nm-thick body without SHE. The alleviation of SHE is due to a) the high thermal conductivity of the substrate assisting on efficiently dissipating the generated thermal energy, b) SHE avoidance with short-pulse measurement, and c) interface engineering between the channel stack and the substrate. These two material systems may be the solid solution to the desire of high current density transistors in the post-Moore era.
Search for the sub-stellar lithium depletion boundary in the open star cluster Coma Berenices

description: We mainly aim to search for the lithium depletion boundary (LDB) among the sub-stellar population of the open star cluster Coma Berenices. We carried out a search for brown dwarf (BD) candidates using colour-magnitude diagrams combining optical and infrared photometry from the latest public releases of the following large-scale surveys: UKIRT/UKIDSS, Pan-STARRS, SDSS, and AllWISE. We checked astrometric consistency with cluster membership using $Gaia$ DR2. A couple dozen new candidate BDs located inside the tidal radius of Coma Ber are reported, but none of these are significantly fainter and cooler than previously known members. A search for Li in three new and five previously known BD candidate cluster members was performed via spectroscopic observations using the OSIRIS instrument at the 10.4-m GTC. No LiI resonance doublet at 6707.8 A was detected in any of eight Coma Ber targets in the magnitude range J=15--19 and G=20--23 observed with the GTC. Spectral types and radial velocities were derived from the GTC spectra. These values confirm the cluster membership of four L2--L2.5 dwarfs, two of which are new in the literature. The large Li depletion factors found among the four bona fide BD members in Coma Ber implies that the LDB must be located at spectral type later than L2.5 in this cluster. Using the latest evolutionary models for BDs, a lower limit of 550 Myr on the cluster age is set. This constraint has been combined with other dating methods to obtain an updated age estimate of 780$\pm$230 Myr for the Coma Ber open cluster. Identification of significantly cooler sub-stellar cluster members in Coma Ber awaits the advent of the Euclid wide survey, which should reach a depth of about J=23; this superb sensitivity will make it possible to determine the precise location of the sub-stellar LDB in this cluster and to carry out a complete census of its sub-stellar population.

description: We show that color ferromagnetic phase of quark matter is energetically more favored than color superconducting phases in neutron stars. Namely, increasing baryon density in neutron stars transforms nuclear matter into the quark matter of the color ferromagnetic phase. Further increase of the density makes the quark matter take the color superconducting phases. We find that a critical mass of the neutron star with such an internal structure is about $1.6M_{\odot}$. We stress that analysis of gluon dynamics is crucial for exploring dense quark matter.

description: We review our recent work about the stability of strange few-body systems containing $N$'s, $Λ$'s, and $Ξ$'s. We make use of local central Yukawa-type Malfliet-Tjon interactions reproducing the low-energy parameters and phase shifts of the nucleon-nucleon system and the latest updates of the hyperon-nucleon and hyperon-hyperon ESC08c Nijmegen potentials. We solve the three- and four-body bound-state problems by means of Faddeev equations and a generalized Gaussian variational method, respectively. The hypertriton, $Λnp$ $(I)J^P=(1/2)1/2^+$, is bound by 144 keV; the recently discussed $Λnn$ $(I)J^P=(1/2)1/2^+$ system is unbound, as well as the $ΛΛnn$ $(I)J^P=(1)0^+$system, being just above threshold. Our results indicate that the $ΞNN$, $ΞΞN$ and $ΞΞNN$ systems with maximal isospin might be bound.

description: This study shows that the carbon star CGCS 673 is a semi-regular (SR) variable star with a period of 135 d and an amplitude of 0.18 magnitudes in the V-band. The light curve obtained by this study correlates well with the SR classification as the photometric data obtained shows noticeable periodicity in the light changes of CGCS 673 that is occasionally interrupted by a period of irregular variability. The derived period and colour index obtained from our data and those from professional databases indicate that the at-tributes of this star fall within the parameters of the Semi-Regular class of variable stars. Following our notification of the discovery that this star is a variable source, CGCS 673 has received the AAVSO Unique Identifier as (AAVSO UID) 000-BMZ-492.

description: Seismic insulation is one of the most progressive types of seismic protection. Seismic insulation is understood as applying special devices for reducing of inertial seismic loads acting on a building. The constructions, shown in article, significantly more effectively solve problems of seismic protection, comparing to the existing seismic insulation systems (SIS). The Special Mechanical Engineering Design Office has developed, manufactured and tested a shock-absorber unit (SAU) of large load capacity. The SAU represents a block of number of pneumatic shock-absorbers (PSA), concentrically mounted round the guiding cylinder. The protected object rests upon the upper movable part of the guiding cylinder of the SAU. In its turn, the lower part of the SAU is rested on the foundation plate, mounted on the ground. A set of the SAU is a constructive realization of the SIS. Efficiency of such SIS has been proved as theoretically, so experimentally An effective SIS can also be created on the base of the elasto-plastic shock-absorbers developed by the KBSM. New designing and constructional solutions are based on the use of the original SIS elements, performed on the base of long time existing (in the other field of technical equipment)units, safety and durability of which have been proved by long term service (more than 20 years).

Among existing lectures in the Internet there will arise a new competition between the universities in netbased teaching and learning environments. For the use of distributed sources of information and for the possibility to generate free configurable sequences of education modules you need management systems which are able to handle different formats of documents and to assemble it to consistent and valid lessons. Beside elementar viewing-functions, fusion of information also administrative tasks are needed, e.g. automated efficiency controls, adaptive learning surroundings. This paper attends to three aspects: - netbased teaching and learning in the area of the instruction of civil engineers - netbased information assembling and fusion of knowledge bases to higher level documents - netbased learning with international coordinated projects

A Long-Lived Accretion Disk Around a Lithium-Depleted Binary T Tauri Star
Creators: name: White, Russel

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present a high dispersion optical spectrum of St 34 and identify the system as a spectroscopic binary with components of similar luminosity and temperature (both M3+/-0.5). Based on kinematics, signatures of accretion, and location on an H-R diagram, we conclude that St 34 is a classical T Tauri star belonging to the Taurus-Auriga T Association. Surprisingly, however, neither component of the binary shows LiI 6708 A, absorption, the most universally accepted criterion for establishing stellar youth. In this uniquely known instance, the accretion disk appears to have survived longer than the lithium depletion timescale. We speculate that the long-lived accretion disk is a consequence of the sub-AU separation companion tidally inhibiting, though not preventing, circumstellar accretion. Comparisons with pre-main sequence evolutionary models imply, for each component of St 34, a mass of 0.37+/-0.08 Msun and an isochronal age of 8+/-3 Myr, which is much younger than the predicted lithium depletion timescale of ~ 25 Myr. Although a distance 38% closer than that of Taurus-Auriga or a hotter temperature scale could reconcile this discrepancy at 21-25 Myr, similar discrepancies in other systems and the implications of an extremely old accreting Taurus-Auriga member suggest instead a possible problem with evolutionary models. Regardless, the older age implied by St 34's depleted lithium abundance is the first compelling evidence for a substantial age spread in this region. Additionally, since St 34's coeval co-members with early M spectral types would likewise fail the lithium test for youth, current membership lists may be incomplete.

description: We report two novel determinations of |Vub| with reduced model dependence, based on measurements of the mass distribution of the hadronic system in semileptonic B decays. Events are selected by fully reconstructing the decay of one B meson and identifying a charged lepton from the decay of the other B meson from Y(4S) to BBbar events. In one approach, we combine the inclusive B to X_u l nu rate, integrated up to a maximum hadronic mass m_X < 1.67GeV, with a measurement of the inclusive B to X_s gamma photon energy spectrum. We obtain |Vub| = (4.43 +- 0.38stat +- 0.25syst +- 0.29theo)*10^-3. In another approach we measure the total B to X_u l nu rate over the full phase space and find |Vub| = (3.84 +- 0.70stat +- 0.30syst +- 0.10theo)*10^-3.

description: We report the discovery of PM J13420-3415, a faint (V=17) white dwarf with a very high proper motion mu = 2.55 arcsec/yr. The star was found in the southern sky extension of the SUPERBLINK proper motion survey. A red spectrum shows the classical signature of a DA white dwarf, with a weak H-alpha line in absorption as the only prominent feature. The star is also found to have a large radial velocity V_rad = +212+/-15 km/s. At the adopted distance of 18 pc, the star has a very large space motion of 313 km/s relative to the Sun. An integration of the space motion shows that the star is on a nearly polar Galactic orbit, and is thus an unambiguous member of the Galactic halo. However, with an estimated effective temperature 5,000K < T_eff < 5,500K, the white dwarf appears to be much younger than expected for a denizen of the halo. The apparent paradox can be explained if the white dwarf is the relatively young (~2 Gyr) remnant of a longer-lived (10-14 Gyr) main sequence star, in which case the object is predicted to be a low-mass white dwarf with M ~ 0.45 M_sun.

description: Global coronal waves (CWs) and their interaction with coronal holes (CHs) result, among other effects, in the formation of reflected and transmitted waves. Observations of such events provide us with measurements of different CW parameters, such as phase speed and intensity amplitudes. However, several of these parameters are provided with only intermediate observational quality, other parameters, such as the phase speed of transmitted waves, can hardly be observed in general. We present a new method to estimate crucial CW parameters, such as density and phase speed of reflected as well as transmitted waves, Mach numbers and density values of the CH's interior, by using analytical expressions in combination with basic and most accessible observational measurements. The transmission and reflection coefficients are derived from linear theory and subsequently used to calculate estimations for phase speeds of incoming, reflected and transmitted waves. The obtained analytical expressions are validated by performing numerical simulations of CWs interacting with CHs. This new method enables to determine in a fast and straightforward way reliable CW and CH parameters from basic observational measurements which provides a powerful tool to better understand the observed interaction effects between CWs and CHs.

description: The Leafy Spurge Biological Control program was designed to use insects and plant diseases from the plant's original European habitat to control infestations in the United States. The widespread adoption of biological agents to combat leafy spurge and the initial success in reclaiming previously infested land has prompted an evaluation of the potential future economic benefits of the biological control of leafy spurge in the Upper Midwest. Based on expert opinion and historical data, leafy spurge in Montana, North Dakota, South Dakota, and Wyoming was projected to infest 1.85 million acres, of which, 65 percent was estimated to controlled with biological agents by 2025. Based on a survey of county weed board personnel, North Dakota and Wyoming are further advanced in the use of biological control than Montana and South Dakota. Recovery of rangeland outputs resulting from the biological control of leafy spurge was estimated to create $52.7 million in direct and secondary economic impacts. Biological control of leafy spurge on wildland was estimated to generate $5.6 million annually. By 2025, total economic impacts of the Leafy Spurge Biological Control Program were estimated at $58.4 million (1997 dollars) annually in the four-state region. An additional 876 full-time equivalent secondary jobs would be created as result of the program. Although the economic estimates generated are based on expert opinion and remain sensitive to assumptions regarding the future efficacy of the biological control of leafy spurge, initial evidence suggests the program will be an economic success regardless of the eventual level of control. The assessment of the economic value of the biological control of leafy spurge would benefit from incorporation of additional information as the overall understanding of the biological control process grows.

description: Das Ziel der Arbeit war es, die Standsicherheit eines Bahndammes im Vergleich der in Deutschland gültigen Vorschriften (DIN 1054 und Eurocode 7) zu untersuchen. Sollte sich dabei herausstellen, dass der Bahndamm in der gegebenen Situation die Standsicherheitsanforderungen nicht erfüllt sollten verschiedene Sanierungsvarianten vorgeschlagen und für eine Vorzugsvariante die wichtigsten Nachweise durchgeführt werden. Zunächst wurden die Allgemeinen Grundlagen der zur Zeit in Deutschland gültigen Vorschriften erläutert und anschließend auf das konkrete Projekt bezogen gegenübergestellt. Es stellte sich heraus, dass die Anforderungen an die Standsicherheit bei Berechnung nach beiden Vorschriften nicht erfüllt werden konnten. Somit war es notwendig für die gegebene Situation mögliche Sanierungsvorschläge zu entwickeln. Diese wurden anschließend kurz vorgestellt und erläutert. Schließlich wurden für die Vorzugsvariante die wichtigsten Nachweise im Vergleich der Vorschriften (DIN 1054 und Eurocode 7) durchgeführt und verglichen.

subject: North Dakota

description: The performance of over 530 North Dakota farms, 1996-1998, is summarized using 16 financial measures. Farms are categorized by geographic region, farm type, farm size, gross cash sales, farm tenure, net farm income, debt-to-asset, and age of farmer to analyze relationships between financial performance and farm characteristics. There was severe deterioration of financial performance in 1997. Financial performance in 1998, although the second lowest in the 1991-1998 period, improved because strong crop yields and emergency federal aid helped offset low crop and livestock prices. Median farm net income was $19,491 in 1998, $14,290 in 1997 and $31,603 in 1996. One-fourth of farms had negative net farm income and 51 percent of farms were not able to make scheduled term debt payments with 1998 income.

description: Thema dieser Arbeit ist die Erstellung einer Prozess-Simulation in einer Echtzeit VR-Umgebung. Besonderes Augenmerk wird dabei der Erfassung des Zeitparameters einzelner Prozessabschnitte geschenkt. Mittels einer Datenbankanbindung können somit Daten zwischen einer externen Datenbank und der Simulation ausgetauscht werden. Neben der Realisierung des Datenzugriffes wurde eine Uhr in der virtuellen Umgebung realisiert un somit das Wechselspiel zwischen Erdbaumaschiene und Transportgerät modelliert. Im schriftlichen Teil dieser Arbeit werden die Grundlagen dazu behandelt, das baubetriebliche Anliegen untersucht und die Erstellung in der Software Quest3D dokumentiert.
Lifetimes of Confined Optical Phonons and the Shape of a Raman Peak in Disordered Nanoparticles: II. Numerical Treatment

description: Disorder-induced broadening of optical vibrational eigenmodes in nanoparticles of nonpolar crystals is studied numerically. The methods previously used to treat phonons in defectless particles are adjusted for numerical evaluation of the disordered problem. Imperfections in the form of Gaussian and binary disorders as well as surface irregularities are investigated thoroughly in a wide range of impurity concentrations and disorder strengths. For dilute and weak point-like impurities the regimes of separated and overlapped phonon levels are obtained and the behavior of the linewidth predicted theoretically is confirmed, the crossover scale falls into the actual range of several nanometers. These notions survive for strong dilute impurities, as well. Regimes and crossovers predicted by theory are checked and identified, and minor discrepancies are discussed. To mention a few of them: slower than in theory increasing of the linewidth with the phonon quantum number for weak disorder and only qualitative agreement between theory and numerics for resonant broadening in strong dilute disorder. The novel phenomena discovered numerically are: "mesoscopic smearing" of distribution function in the ensemble of identical disordered particles, inflection of the linewidth dependence on the impurity concentration for light "dense" binary impurities, and position-dependent capability of strong impurity to catch the phonon. It is shown that surface irregularities contribute to the phonon linewidth less than the volume disorder, and their rate reveals faster decay with increasing of the particle size. It is argued that the results of present research are applicable also for quantum dots and short quantum wires.

description: We derive novel conditions that guarantee convergence of the Sum-Product algorithm (also known as Loopy Belief Propagation or simply Belief Propagation) to a unique fixed point, irrespective of the initial messages. The computational complexity of the conditions is polynomial in the number of variables. In contrast with previously existing conditions, our results are directly applicable to arbitrary factor graphs (with discrete variables) and are shown to be valid also in the case of factors containing zeros, under some additional conditions. We compare our bounds with existing ones, numerically and, if possible, analytically. For binary variables with pairwise interactions, we derive sufficient conditions that take into account local evidence (i.e., single variable factors) and the type of pair interactions (attractive or repulsive). It is shown empirically that this bound outperforms existing bounds.

description: A survey of 459 ranchers, 56 local decision makers, and 50 public land managers (565 total) was conducted to evaluate managerial, institutional, and social factors that may affect the rate and extent of implementation of various leafy spurge (Euphorbia esula L.) controls. The study focused on a five-county region in Montana, North Dakota, South Dakota, and Wyoming. The questionnaire focused on weed management in general and specifically on the perceptions and attitudes of ranchers, land managers, and local decision makers who have been directly and indirectly affected by leafy spurge.

description: Today, most astronomers would probably place their bets on the microwave background radiation providing the most secure estimate of the age of the Universe. But there are a number of nearby stars whose estimated ages push at the limits of this inferred upper bound. Accurate distances are crucial to a better understanding.
