Study is presented to show how solution conditions, especially solvent polarity and hydrogen bonding affect the fluorescence of ellipticine, a natural plant alkaloid with anticancer activity. A total of 16 solvents that cover a wide range of polarities were tested. A relatively large red shift of emission in liposomes indicated that ellipticine might be in a more polar environment with respect to the lipid bilayer, possibly close to the hydrophilic interface.

Successful project delivery of construction projects depends on many factors. With regard to the construction of a facility, selecting a competent contractor for the job is paramount. As such, various approaches have been advanced to facilitate tender award decisions. Essentially, this type of decision involves the prediction of a bidder’s performance based on information available at the tender stage. A neural network based prediction model was developed and presented in this paper. Project data for the study were obtained from the Hong Kong Housing Department. Information from the tender reports was used as input variables and performance records of the successful bidder during construction were used as output variables. It was found that the networks for the prediction of performance scores for Works gave the highest hit rate. In addition, the two most sensitive input variables toward such prediction are “Difference between Estimate” and “Difference between the next closest bid”. Both input variables are price related, thus suggesting the importance of tender sufficiency for the assurance of quality production.

Experiments E866 and E917 at the AGS have measured the differential invariant yields of positive and negative charged kaons from Au+Au collisions at beam kinetic energies in the laboratory of 2, 4, 6, 8, and 10.8 A·GeV. At each beam energy, a multiplicity array is used to select on the centrality of the collision.

A Multiplicity-Vertex Detector (MVD) has been designed, and is in construction for the PHENIX Experiment at the Relativistic Heavy Ion Collider (RHIC). The 35 000 channel silicon detector is a two-layer barrel comprised of 112 strip detectors, and two disk-shaped endcaps comprised of 24 wedge-shaped pad detectors. The support structure of the MVD is very low mass, only 0.4% of a radiation length in the central barrel. The detector front-end electronics are a custom CMOS chip set containing preamplifier, discriminator, analog memory unit, and analog-to-digital converter. The system has pipelined acquisition, performs in simultaneous read/write mode, and is clocked by the 10 MHz beam crossing rate at RHIC. These die, together with a pair of commercial FPGAs that are used for control logic, are packaged in a mutlichip-module (MCM). The MCM will be fabricated in the High-Density-Interconnect (HDI) process. The prototype MCM design layout is described.

This paper presents recent results from Experiment 859 at the BNL AGS, focussing on strangeness ( K ± , Λ, Λ ), rare probes ( p , φ) and two-particle correlations. Highlights of the paper include an analysis of the centrality dependence of K ± yields in terms of the number of participants, a brief review of the current status of the E859 Λ and Λ data, an analysis of the target dependence of p yields in terms of p K − ratio's, results of a re-analysis of Λ feed-down contamination of p 's, a comparison of the cenal SiAu and pp φ yields through the φ K − ratio, an extremely preliminary study of the centrality dependence of the φ line-shape, a summary of the centrality dependence of two-π correlation source sizes, and a comparison of results from two-dimensional analyses of the two-π and two-K + correlation functions.

Staging of gastric adenocarcinoma is important for comparing aspects of the disease in Asia and in the Western countries, and it may be used to direct the treatment strategy. A survey of 13 popular current surgical textbooks and review journals found a high level of inaccuracy. Two texts (15%) did not mention any staging systems, and one (8%) described a nonstandard system. Three (23%) described staging systems that were out of date, and six descriptions (46%) were inaccurate. Only 40% of the cited staging systems was reliable. This level of inaccuracy leads to confusion for the reader and to difficulty interpreting other relevant literature.

Publisher Summary Molecular self-assembly is the spontaneous organization of molecules under near thermodynamic equilibrium conditions into structurally well-defined and stable arrangements through non-covalent interactions. Such interactions typically include hydrogen bonding, electrostatic attraction, and van der Walls interactions. Frequently, molecular self assembly relies on chemical complementarity and structural compatibility. These fundamentals are critical to the design of molecular building blocks required for the fabrication of functional macrostructures. Molecular fabrication involves not only the understanding of molecular self-assembly, but also the knowledge of surface science. Materials communicate with their environment via their interfaces. Such communications are determined by the interfacial properties of the materials. In particular, understanding the molecular mechanisms and signaling cascades between living cells and their environment is crucial to fabricate novel biomaterials; biomineralization requires functional templates to direct and regulate the mineral deposition and the crystal growth. The molecular interactions in molecular self-assembly, in guest-host molecular recognition, and in molecular biomimetics are governed by the interfacial communications, which eventually control the material structures and their mechanical, electronic, magnetic, and solution properties.

Positive pion and kaon production from Au+Au reactions have been measured as a function of beam energy over the range 2.0-10.7~AGeV. Both the kaon and the pion production cross-sections at mid-rapidity are observed to increase steadily with beam kinetic energy. The ratio of K$^+$ to $\pi^+$ mid-rapidity yields increases from 0.0271$\pm0.0015\pm0.0014$ at 2.0~AGeV to 0.202$\pm0.005\pm0.010$ at 10.7~AGeV and is larger than the K$^+$/$\pi^+$ ratio from p+p reactions over the same beam energy region. There is no indication of an onset of any new production mechanism in heavy-ion reactions in this energy range beyond rescattering of hadrons., Comment: 9 pages, 4 figures, submitted to Phys. Lett. B

The multiparticle Bose correlations of bosons emitted from dispersed thermal droplets of quark-gluon plasma are simulated by a Monte Carlo process. Multiparticle Bose correlations can offer more sensitivity to probe the granularity of the boson-emitting source than two-particle Bose correlations. A promising signal of the existence of a mixed phase of quark-gluon plasma and hadronic gas can be obtained from multiparicle observables.

We analyse the variation of the average transverse momentum, 〈pT〉, with the multiplicity of charged particles produced in pp, pp, dd and αα collisions at ISR energies. An increase of 〈pT〉 with increasing particle density p=ΔnΔy for charged particles produced in the central region is observed. The energy dependence of this effect and its dependence on the type of colliding particles are discussed.

Leaves of some host plants of European small ermine moths of the genus Yponomeuta: Euonymus europaeus, Crataegus sp., Malus sp., Prunus cerasifera, P. mahaleb, P. padus, P. spinosa and Sorbus aucuparia , were examined on the joint occurrence of the isomeric sugar alcohols dulcitol and sorbitol. Sorbitol and a trace of dulcitol (0.1–0.5% dry weight) were present in the rosaceous species P. padus and P. spinosa . Seasonal variation in the sugar and sugar alcohol contents was also determined. The role of sugar alcohols in the feeding behaviour of Yponomeuta spp. is considered.

To probe the early, high density stage of a heavy-ion collision, it is essential to focus on observables that are minimally distorted during the subsequent processes of expansion, decay of excited states, and chemical freeze-out. It is now widely accepted that correlations characteristic of fluid-like collective behavior (“flow”) fulfill these requirements. Such correlations signal the release of compressional energy, and provide a relative measure of the peak nuclear pressure generated in the collision.

We report preliminary results for uranium on uranium collisions at the LBL streamer chamber facility, at the maximum Bevalac incident energy. Global event parameters are compared with results for Ar on KCl in the same energy region, and with intranuclear cascade model predictions. We also report results of temperature fits to negative pion spectra.
