description: A large-scale configuration-interaction (CI) calculation is reported for the hyperfine splitting of the 2^2S and 3^2S states of ^7Li and ^9Be^+. The CI calculation based on the Dirac-Coulomb-Breit Hamiltonian is supplemented with a separate treatment of the QED, nuclear-size, nuclear-magnetization distribution, and recoil corrections. The nonrelativistic limit of the CI results is in excellent agreement with variational calculations. The theoretical values obtained for the hyperfine splitting are complete to the relative order of α^2 and improve upon results of previous studies.

description: This thesis tested the hypothesis that the inadequate tumor delivery of anticancer agents and selectivity of PGP modulation are primarily responsible for the attenuated therapy of extravascular MDR solid tumors overexpressing PGP. PSC 833 was selected as the MDR modulator for in vivo applications, based on potency, extent of MDR reversal and latent modulating activity. Whereas co-administration of PSC 833 with non-encapsulated DOX required a 3-fold reduction in anticancer drug dose due to increased toxicity, the toxicity of DOX encapsulated in 100 nm diameter DSPC/Chol vesicles was comparable in the presence and absence of PSC 833. Efficacy studies in P388/ADR solid tumor bearing mice revealed that co-administration of non-encapsulated DOX and PSC 833 at the maximum tolerated dose (MTD) resulted in modest MDR modulation and antitumor activity. However, significant tumor growth suppression was observed when DSPC/Chol DOX was co-administered with PSC 833. Pharmacokinetic studies indicated a PSC 833-induced increase in terminal elimination phase and a concomitant 10-fold increase in plasma DOX AUC following treatment with non-encapsulated DOX whereas minimal pharmacokinetic alterations were observed with DOX encapsulated in DSPC/Chol liposomes. The relative toxicities and degree of MDR reversal were also examined using leaky and non-leaky liposomal DOX in the presence and absence of PSC 833. While PSC 833 necessitated a 3-fold dose reduction for the leaky EPC/Chol DOX in the multiple dosing schedule, no dose reductions were required for the non-leaky PEG-DSPE/DSPC/Chol DOX. In human breast carcinoma MDR xenograft tumor bearing mice, co-administration of EPC/Chol DOX and PSC 833 resulted in modest modulation and antitumor activity. However, co-administration of PSC 833 with non-leaky liposomal DOX resulted in significant tumor growth suppression comparable to that obtained using drug sensitive tumors. PSC 833 caused a 2.6-fold increase in plasma DOX AUC when co-administered with EPC/Chol DOX, whereas PSC 833 did not alter the pharmacokinetics of DOX encapsulated in sterically stabilized liposomes. The renal (CLr) and biliary (CLb) clearances of non-encapsulated DOX were found to be significantly inhibited by PSC 833. While the CLr and CLb of the EPC/Chol and PEG-DSPE/DSPC/Chol DOX were considerably lower than for non-encapsulated drug, PSC 833 co-administration resulted in minor inhibitions of CLr and CLb for the EPC/Chol DOX formulation. PEG-DSPE/DSPC/Chol DOX clearances were unaltered by the MDR modulator. These results confirmed the ability of liposome encapsulation to modify the distribution and metabolism of DOX in a manner that alleviates the effects of PSC 833 on DOX pharmacokinetics observed using non-encapsulated drug.

description: We demonstrate that turbulent zonal jets, analogous to Jovian ones, which are quasi-stationary, are actually metastable. After extremely long times, they randomly switch to new configurations with a different number of jets. The genericity of this phenomenon suggests that most quasi-stationary turbulent planetary atmospheres might have many climates and attractors for fixed values of the external forcing parameters. A key message is that this situation will usually not be detected by simply running the numerical models, because of the extremely long mean transition time to change from one climate to another. In order to study such phenomena, we need to use specific tools: rare event algorithms and large deviation theory. With these tools, we make a full statistical mechanics study of a classical barotropic beta-plane quasigeostrophic model. It exhibits robust bimodality with abrupt transitions. We show that new jets spontaneously nucleate from westward jets. The numerically computed mean transition time is consistent with an Arrhenius law showing an exponential decrease of the probability as the Ekman dissipation decreases. This phenomenology is controlled by rare noise-driven paths called {\it instantons}. Moreover, we compute the saddles of the corresponding effective dynamics. For the dynamics of states with three alternating jets, we uncover an unexpectedly rich dynamics governed by the symmetric group ${\cal S}_3$ of permutations, with two distinct families of instantons, which is a surprise for a system where everything seemed stationary in the hundreds of previous simulations of this model. We discuss the future generalization of our approach to more realistic models.

description: The prospect of trade liberalization at both the regional and global level opens up the possibility of increased agricultural investment in developing countries. Such opportunities can be very appealing to developed-country producers who face high domestic costs, particularly for land and labor. Further, foreign investment could be an extremely positive development in terms of using developed country technical knowledge to increase global food production. However putting this experience into practice overseas has not always been successful in the past. The history of expatriate investment in developing country agriculture does not offer many encouraging examples. Often overlooked in the literature of both agricultural economics and management, private investment in large-scale agricultural production, mostly undertaken by agribusinesses, has a poor record. Five case studies examined in this paper offer examples of what goes wrong which such investments. Based on the experience of these operations, it is the thesis of this paper that the main adaptation that these projects might have made is in the role of management.

description: We investigate the dynamics of polymer translocation through a nanopore under an externally applied field using the 2D fluctuating bond model with single-segment Monte Carlo moves. We concentrate on the influence of the field strength $E$, length of the chain $N$, and length of the pore $L$ on forced translocation. As our main result, we find a crossover scaling for the translocation time $τ$ with the chain length from $τ\sim N^{2ν}$ for relatively short polymers to $τ\sim N^{1 + ν}$ for longer chains, where $ν$ is the Flory exponent. We demonstrate that this crossover is due to the change in the dependence of the translocation velocity v on the chain length. For relatively short chains $v \sim N^{- ν}$, which crosses over to $v \sim N^{- 1}$ for long polymers. The reason for this is that with increasing $N$ there is a high density of segments near the exit of the pore, which slows down the translocation process due to slow relaxation of the chain. For the case of a long nanopore for which $R_\parallel $, the radius of gyration $R_{g}$ along the pore, is smaller than the pore length, we find no clear scaling of the translocation time with the chain length. For large $N$, however, the asymptotic scaling $τ\sim N^{1 + ν}$ is recovered. In this regime, $τ$ is almost independent of $L$. We have previously found that for a polymer, which is initially placed in the middle of the pore, there is a minimum in the escape time for $R_\parallel \approx L$. We show here that this minimum persists for a weak fields $E$ such that $EL$ is less than some critical value, but vanishes for large values of $EL$.

description: BMS symmetry is a symmetry of asymptotically flat spacetimes in the vicinity of the null boundary of spacetime and it is expected to play a fundamental role in physics. It is interesting therefore to investigate the structures and properties of quantum deformations of these symmetries, which are expected to shed some light on symmetries of quantum spacetime. In this paper we discuss the structure of the algebra of extended BMS symmetries in 3 and 4 spacetime dimensions, realizing that these algebras contain an infinite number of distinct Poincaré subalgebras, a fact that has previously been noted in the 3-dimensional case only. Then we use these subalgebras to construct an infinite number of different Hopf algebras being quantum deformations of the BMS algebras. We also discuss different types of twist-deformations and the dual Hopf algebras, which could be interpreted as noncommutative, extended quantum spacetimes.

GADD45 PLAYS A ROLE IN P53-DEPENDENT G2/M CHECKPOINT CONTROL
Creators: name: Coursen, Jill Diane
Publisher: name: Maryland Shared Open Access Repository
Year: 1996

description: The G1/S and G2/M cell cycle checkpoints are important for maintaining eukaryotic genomic stability in response to genotoxic stress. The p53 tumor suppressor protein plays a central role in regulating both Gl/S and G2/M checkpoints and also regulates programmed cell death (apoptosis) in response to DNA damage. It is thought that p53 mediates these pathways by acting as a transcription factor to transactivate downstream target genes and by directly interacting with cellular proteins. While p53 regulation of the G1/S checkpoint and apoptosis have been extensively studied, the mechanism of the p53-mediated G2/M checkpoint is poorly understood. We report here that Gadd45, a member of the growth arrest and DNA damage-inducible (GADD) gene family and a downstream target for p53 transactivation, plays an important role in G2/M checkpoint regulation. Overexpression of Gadd45 via microinjection of an expression vector into primary normal human fibroblasts resulted in cell cycle arrest primarily at the G2/M boundary, characterized by mitotic morphology, tetraploid DNA content, and expression of mitotic epitopes. These arrested cells have not formed a mitotic spindle and contain a single centrosome. The arrest is dependent on wild-type p53, since no arrest was observed in either Li- Fraumeni fibroblast cells that have homozygous loss of p53, or in normal fibroblasts when Gadd45 was co-expressed with dominant negative p53 mutants. Flow cytometry analysis confirmed that Gadd45 induced a p53- dependent G2/M arrest in a colon cancer cell line. Furthermore, cells with diminished endogenous Gadd45 failed to arrest at G2/M following ultraviolet light radiation or methyl methanesulfonate exposure. However, these cells still retained a functional G2/M checkpoint following ionizing radiation. These results indicate that Gadd45 plays an essential role in controlling at least one of the G2/M checkpoints in response to DNA damage.

We estimate the electric quadrupole reduced matrix element of the S$_{1/2}$ $\leftrightarrow$ D$_{5/2}$ transition to be 12.5(4) $e a_0^2$. Furthermore, we determine the transition frequency of the F$_{7/2}$ $\leftrightarrow$ $^{1}$D$[3/2]_{3/2}$ at 760 nm with a $\sim$25-fold improvement in precision. These measurements provide benchmarks for quantum-many-body atomic-physics calculations and provide valuable data for efforts to improve quantum information processors based on Yb$^+$.

An overview of the white-bearded wildebeest (Connochaete taurnius albojabatus) with suggestions for future management
Creators: name: Cowan, Patricia
Publisher: name: Maryland Shared Open Access Repository
Year: 1984

description: The white-bearded wildebeest (Connochaetea taurnius albojubatus) is a medium size, gregarious ungulate. Its natural habitat is the open grasslands of Tanzania and Kenya. It selectively consumes grasses which are less than ten centimeters high, preferring Themeda trianda. It will migrate approximately eighteen hundred kilometers annually to maintain its supply of short grasses and surface water. The herds are comprised of selectively anonymous aggregations with no hierarchy or pecking order. Temporary territories are established by some adult males during the rutting season which occurs over a three week period in April and May. After a gestation period of eight to nine months, some 80% of the calves are born on the Serengeti Plains over a three week period in January to February. Although predators and pathological conditions offer some threat to the wildebeest, its major threat is the swelling human population in East Africa. Without proper management planning for both the wildebeest and humans, there will be a severe conflict between the two species. If the wildebeest can serve a useful purpose to the sprawling human population, then perhaps, they will at least tolerate the wildebeests' presence. One suggestion for the wildebeests' management is to have the wildebeest serve as a food source for the general population in East Africa as well as an exported food stuff. A second suggestion is to preserve the herds as they are today allowing the animals to be a basis for the prosperous tourist industry. The revenue brought in by the tourist industry would then be used to improve the human condition in East Africa. In either case, without proper human population control, all management planning for the wildebeest is pointless. A key to successful human population control is education. Time is running out for both the human and wildebeest populations in the semi-arid nations of East Africa.

description: We reanalyze high resolution data from the New York Stock Exchange and find a monotonic (but not power law) variation of the mean value per trade, the mean number of trades per minute and the mean trading activity with company capitalization. We show that the second moment of the traded value distribution is finite. Consequently, the Hurst exponents for the corresponding time series can be calculated. These are, however, non-universal: The persistence grows with larger capitalization and this results in a logarithmically increasing Hurst exponent. A similar trend is displayed by intertrade time intervals. Finally, we demonstrate that the distribution of the intertrade times is better described by a multiscaling ansatz than by simple gap scaling.

description: A multiscale model for real-time simulation of terrain dynamics is explored. To represent the dynamics on different scales the model combines the description of soil as a continuous solid, as distinct particles and as rigid multibodies. The models are dynamically coupled to each other and to the earthmoving equipment. Agitated soil is represented by a hybrid of contacting particles and continuum solid, with the moving equipment and resting soil as geometric boundaries. Each zone of active soil is aggregated into distinct bodies, with the proper mass, momentum and frictional-cohesive properties, which constrain the equipment's multibody dynamics. The particle model parameters are pre-calibrated to the bulk mechanical parameters for a wide range of different soils. The result is a computationally efficient model for earthmoving operations that resolve the motion of the soil, using a fast iterative solver, and provide realistic forces and dynamic for the equipment, using a direct solver for high numerical precision. Numerical simulations of excavation and bulldozing operations are performed to validate the model and measure the computational performance. Reference data is produced using coupled discrete element and multibody dynamics simulations at relatively high resolution. The digging resistance and soil displacements with the real-time multiscale model agree with the reference model up to 10-25%, and run more than three orders of magnitude faster.

description: This paper is devoted to study some properties of the k-dimensional Lyness' map. Our main result presentes a rational vector field that gives a Lie symmetry for F. This vector field is used, for k less or equal to 5 to give information about the nature of the invariant sets under F. When k is odd, we also present a new (as far as we know) first integral for F^2 which allows to deduce in a very simple way several properties of the dynamical system generated by F. In particular for this case we prove that, except on a given codimension one algebraic set, none of the positive initial conditions can be a periodic point of odd period.

description: JWST holds great promise in characterizing atmospheres of transiting exoplanets, potentially providing insights into Earth-sized planets within the habitable zones of M dwarf host stars if photon-limited performance can be achieved. Here, we discuss the systematic error sources that are expected to be present in grism time series observations with the NIRCam instrument. We find that pointing jitter and high gain antenna moves on top of the detectors' subpixel crosshatch patterns will produce relatively small variations (less than 6 parts per million, ppm). The time-dependent aperture losses due to thermal instabilities in the optics can also be kept to below 2 ppm. To achieve these low noise sources, it is important to employ a sufficiently large (more than 1.1 arcseconds) extraction aperture. Persistence due to charge trapping will have a minor (less than 3 ppm) effect on time series 20 minutes into an exposure and is expected to play a much smaller role than it does for the HST WFC3 detectors. We expect temperature fluctuations to be less than 3 ppm. In total, our estimated noise floor from known systematic error sources is only 9 ppm per visit. We do however urge caution as unknown systematic error sources could be present in flight and will only be measurable on astrophysical sources like quiescent stars. We find that reciprocity failure may introduce a perennial instrument offset at the 40 ppm level, so corrections may be needed when stitching together a multi-instrument multi-observatory spectrum over wide wavelength ranges.

Publisher: name: Maryland Shared Open Access Repository
Year: 2008

description: The Maryland Chapter of the American Chestnut Foundation (MDTACF) maintains several orchards across the state of Maryland to raise backcrossed chestnut trees to aid in the development of blight-resistant strains. Over 700 chestnut trees at five different orchards were followed during their first growing season to test the effect of geographic region (Coastal Plain, Piedmont, or Appalachian) and genotype on tree height and survival. Application of fertilizer was also noted and its effects were analyzed. The highest average height was seen in the Piedmont region, followed respectively by trees in the Appalachian and Coastal Plain regions. Mortality did not differ consistently by region, with both the highest and lowest percentage of trees dead in the Piedmont orchards, and Coastal Plain and Appalachian orchards at similar rates in between. Genotype was highly significant with respect to mortality, and the SE 833 x CH526 genotype resulted in the tallest trees. Fertilizer application was not significant in relation to mean height or survival.

description: We simulate the tapping of a bed of hard disks in a rectangular box by using a pseudo dynamic algorithm. In these simulations, arches are unambiguously defined and we can analyze their properties as a function of the tapping amplitud. We find that an order--disorder transition occurs within a narrow range of tapping amplitudes as it has been seen by others. Arches are always present in the system althought they exhibit regular shapes in the ordered regime. Interestingly, an increase in the number of arches does not always correspond to a reduction in the packing fraction. This is in contrast with what is found in three-dimensional systems.

description: We employ the functional renormalization group framework at the second order in the derivative expansion to study the $O(N)$ models continuously varying the number of field components $N$ and the spatial dimensionality $d$. We in particular address the Cardy-Hamber prediction concerning nonanalytical behavior of the critical exponents $ν$ and $η$ across a line in the $(d,N)$ plane, which passes through the point $(2,2)$. By direct numerical evaluation of $η(d,N)$ and $ν^{-1}(d,N)$ as well as analysis of the functional fixed-point profiles, we find clear indications of this line in the form of a crossover between two regimes in the $(d,N)$ plane, however no evidence of discontinuous or singular first and second derivatives of these functions for $d>2$. The computed derivatives of $η(d,N)$ and $ν^{-1}(d,N)$ become increasingly large for $d\to 2$ and $N\to 2$ and it is only in this limit that $η(d,N)$ and $ν^{-1}(d,N)$ as obtained by us are evidently nonanalytical. By scanning the dependence of the subleading eigenvalue of the RG transformation on $N$ for $d>2$ we find no indication of its vanishing as anticipated by the Cardy-Hamber scenario. For dimensionality $d$ approaching 3 there are no signatures of the Cardy-Hamber line even as a crossover and its existence in the form of a nonanalyticity of the anticipated form is excluded.

DO TYPE-D RETRO VIRUSES PLAY A ROLE IN THE AETIOLOGY OF KAPOSI'S SARCOMA?
Creators: name: Cullen, Michael G.
Publisher: name: Maryland Shared Open Access Repository
Year: 1994

description: Acquired and epidemic Kaposi's Sarcoma (KS) is prevalent among human immunodeficiency virus (HIV) positive homosexual males and other immunosuppressed patients as a far more aggressive tumor than classic KS, suggesting that an infectious agent may play a role in its aetiology. That only a subset of HIV infected individuals and some HIV negative individuals acquire KS implies that the HIV virus is not directly responsible for KS. A similar neoplasm, retroperitoneal fibromatosis (RF), is associated with simian acquired immunodeficiency syndrome (SAIDS) in primates, and is considered a model for acquired immunodeficiency syndrome (AIDS) associated KS. The causative agent of SAIDS associated RF is a type-D retrovirus, simian retrovirus type 2 (SRV2). The similarities between the two diseases has invited speculation that KS may also be caused by a type-D retrovirus. Electron microscope images of a budding retroviral particle in association with tissue from KS lesions from HIV-1, HIV-2 and human T-cell leukemia virus type 1 (HTLV-1) seronegative individuals have lent credence to this theory. The study presented here was undertaken in order to determine if a link between exogenous type-D retrovirus infection and Kaposi's Sarcoma exists. A highly sensitive and specific approach utilizing nested polymerase chain reaction (PCR) amplification and subsequent Southern blot analysis was developed and optimized in order to examine the question.

description: This paper reviews and analyzes a literature that examines the restrictiveness of focusing on households as single units of analysis. In particular, this literature asks: To what extent can we use the household as a unit of analysis, and when do we need to disaggregate the household and look at individual behavior within the household? In this paper, I examine the different models of intrahousehold resource allocation and the empirical work they have generated. Each of the models has a different set of assumptions about the four components of household decisions. The assumptions and predictions of each of the main models of intrahousehold resource allocation are presented; then I discuss the empirical work that tests the validity of the assumptions and discuss when the different models may be appropriate.
DNA SEQUENCE ANALYSIS OF OVERLAPPING CHROMOSOMAL DELETIONS IN TWO NINE MILE ISOLATES OF COXIELLA BURNETII
Creators: name: Culp, David W.
Publisher: name: Maryland Shared Open Access Repository
Year: 1994

description: Previous studies on the prototype Nine Mile strain of Coxiella bumetii has shown that two derivatives have overlapping deletions of chromosomal DNA. The Nine Mile phase I parent wild-type isolate is virulent, causing acute 0-fever. The two derivatives, Nine Mile II and RSA 514, have truncated lipopolysaccharide (LPS) structures which differ from the parent Nine Mile I complete smooth LPS. Nine Mile II is avirulent with a rough LPS. RSA 514 has a semi-rough LPS and infects immunocompetent hosts. RSA 514 is similar to Nine Mile II, and superior to 9 mile I, in its ability to gain entry into cells. However, RSA 514's semi-rough LPS only affords partial protection from the host's immune system. To gain information into the genetic basis for these LPS variations the DNA segment corresponding to the DNA deletion regions of Nine Mile ll and RSA 514 was sequenced. Sequence analysis showed the RSA 514 deletion to contain coding sequences for four rfb genes, which have been shown in enteric bacteria to encode for enzymes and/or regulatory functions required for the synthesis of the 0-antigen region of the LPS.

description: We present a method to characterize the polarization state of a light field in the continuous-variable regime. Instead of using the abstract formalism of SU(2) quasidistributions, we model polarization in the classical spirit by superposing two harmonic oscillators of the same angular frequency along two orthogonal axes. By describing each oscillator by a $s$-parametrized quasidistribution, we derive in a consistent way the final function for the polarization. We compare with previous approaches and discuss how this formalism works in some relevant examples.

description: We investigate the role of the initial condition used for the hydrodynamic evolution of the system formed in ultra-relativistic heavy-ion collisions and find that an appropriate choice motivated by the models of early-stage dynamics, specifically a simple two-dimensional Gaussian profile, leads to a uniform description of soft observables measured in the Relativistic Heavy-Ion Collider (RHIC). In particular, the transverse-momentum spectra, the elliptic-flow, and the Hanbury-Brown--Twiss correlation radii, including the ratio R_out/R_side as well as the dependence of the radii on the azimuthal angle (azHBT), are properly described. We use the perfect-fluid hydrodynamics with a realistic equation of state based on lattice calculations and the hadronic gas at high and low temperatures, respectively. We also show that the inclusion of the partonic free-streaming in the early stage allows to delay the start of the hydrodynamical description to comfortable times of the order of 1 fm/c. Free streaming broadens the initial energy-density profile, but generates the initial transverse and elliptic flow. The data may be described equally well when the hydrodynamics is started early, or with a delay due to partonic free-streaming.

New Ideas for Brain Modelling 7

Year: 2020

description: This paper updates the cognitive model, firstly by creating two systems and then unifying them over the same structure. It represents information at the semantic level only, where labelled patterns are aggregated into a 'type-set-match' form. It is described that the aggregations can be used to match across regions with potentially different functionality and therefore give the structure a required amount of flexibility. The theory is that if the model stores information which can be transposed in consistent ways, then that will result in knowledge and some level of intelligence. As part of the design, patterns have to become distinct and that is realised by unique paths through shared aggregated structures. An ensemble-hierarchy relation also helps to define uniqueness through local feedback that may even be an action potential. The earlier models are still consistent in terms of their proposed functionality, but some of the architecture boundaries have been moved to match them up more closely. After pattern optimisation and tree-like aggregations, the two main models differ only in their upper, more intelligent level. One provides a propositional logic for mutually inclusive or exclusive pattern groups and sequences, while the other provides a behaviour script that is constructed from node types. It can be seen that these two views are complimentary and would allow some control over behaviours, as well as memories, that might get selected.
Prompt photon production in proton collisions as a probe of parton scattering in high energy limit

description: We study the prompt photon hadroproduction at the LHC with the $k_T$-factorization approach and the $qg^* \to qγ$ and $g^*g^* \to q\bar qγ$ partonic channels, using three unintegrated gluon distributions which depend on gluon transverse momentum. They represent three different theoretical schemes which are usually considered in the $k_T$-factorization approach, known under the acronyms: KMR, CCFM and GBW gluon distributions. We find sensitivity of the calculated prompt photon transverse momentum distribution to the gluon transverse momentum distribution. The predictions obtained with the three approaches are compared to data, that allows to differentiate between them. We also discuss the significance of the two partonic channels, confronted with the expectations which are based on the applicability of the $k_T$-factorization scheme in the high energy approximation.

Heterogeneity of Carcinoembryonic antigen expression in human colon cancer cell lines.

Publisher: name: Maryland Shared Open Access Repository
Year: 1984

description: Environmental causes of colon cancer have been difficult to elucidate. This is in large part due to the fact that no adequate marker for early neoplastic changes in colon tissue has been found. Carcinoembryonic antigen (CEA) is a glycoprotein that has shown promise in some clinical studies for the detection of colon cancer (Lawrence, 1975; Zamcheck, 1975). In order to study the relationship between CEA and malignancy, I chose to work with a continuously growing human colon cancer line, WiDr (Noguchi, 1975). The original WiDr line is quite heterogeneous in CEA expression, ranging from cells with little or no surface CEA to cells with large amounts of CEA. I have utilized the technology of flow cytometry to select a population of WiDr cells producing an increased amount of CEA. After sorting and growing the cells into bulk culture, the resulting population exhibited a substantial increase in the relative amount of CEA expression, however, expression was still heterogeneous. Correlated DNA-CEA cytograms showed that the increased CEA production was present in all parts of the cell cycle, and was not restricted to any particular phase. The enriched population was tested in nude mice to assess the possible role of CEA in tumorigenicity. Light microscope examination of histologic sections of tumors in nude mice exhibited increased immunoperoxidase localization of CEA in the sorted population. Thus, many of the discrepancies that have been found in the literature may be due to the marked heterogeneity of CEA expression seen in some colon cancers.

description: An R&D based endogenous growth - applied general equilibrium model is developed from an underlying analytical model which combines Romer's capital variety with Grossman and Helpman's multi-sector open economy model. The transitional dynamics of the analytical model are derived. For numerical implementation, a time discrete empirical model, with an Armington structure, is fit to East Asian data of the social accounting matrix variety. Simulations of trade reform are performed and their static and dynamic effects compared. The transition paths of the state variables are found to have a half-life of five to six periods. A solution of the Social Planner's problem, and interventions which seek to obtain this outcome from the decentralized model are also obtained'.
Establishment and Characterization of Cell Cultures from Methapyrileneinduced Liver Tumors in Rats
Creators: name: Currens, Michael J.
Publisher: name: Maryland Shared Open Access Repository
Year: 1984

description: The antihistaminic methapyrilene (MP), which is neither mutagenic in bacterial test systems nor clastogenic in mammalian cells, has been shown by Lijinsky et al. (29) to be a potent hepatocarcinogen in rats. Two cell cultures from primary hepatocellular carcinomas induced by MP were established and characterized for growth, morphology, and physiological characteristics in vitro as compared to tumor cell lines induced by known genotoxic agents. The parameters studied included: growth kinetics, colony formation in semisolid medium, tumorigenesis, karyology, y-glutamyl transpeptidase activity, membrane permeability as measured by 2-deoxyglucose uptake, and growth regulation exerted by an hepatic proliferation inhibitor (HPI). The MP-tumor derived cell cultures resembled tumor cell lines only in their resistance to growth inhibition by HPI. With all other transformation markers the tumor cell cultures resembled normal liver epithelial cells. These results are discussed in view of proposals by Potter (48) and their possible relevance to carcinogenesis.

description: We consider two sequential models of deposition and aggregation for particles. The first model (No Diffusion) simulates surface diffusion through a deterministic capture area, while the second (Sequential Diffusion) allows the atoms to diffuse up to \ell steps. Therefore the second model incorporates more fluctuations than the first, but still less than usual (Full Diffusion) models of deposition and diffusion on a crystal surface. We study the time dependence of the average densities of atoms and islands and the island size distribution. The Sequential Diffusion model displays a nontrivial steady-state regime where the island density increases and the island size distribution obeys scaling, much in the same way as the standard Full Diffusion model for epitaxial growth. Our results also allow to gain insight into the role of different types of fluctuations.

description: By dropping particles into black hole, we have employed the recently new assumption [1] that the change of the black hole mass(enthalpy) should be the same amount as the energy of an infalling particle($ω= dM$), to carefully test the laws of thermodynamics and the weak cosmic censorship conjecture of a conformal anomaly corrected AdS black hole in different phase spaces. Using the energy-momentum relation, the result shows that the first law, second law and weak cosmic censorship conjecture of black hole are all valid in the normal phase space, no violations occur. In the extended phase space, it firstly shows that the first law of black hole thermodynamics is always true in our case. Then, we interestingly find that if the condition ${d\ell} > -\left(P^r \ell^3\right)/{r_+^3}$ satisfied the variation of entropy is always positive, which means there would be no violation of the second law in the extend phase spaces. Also, it is true that there are always horizons by which the singularity is also covered. So, the configurations of the extremal and near-extremal black holes will not be changed, and there has no violation of the weak cosmic censorship conjecture. Finally, all of those conclusions are independent of the scalar curvature parameter $k$ and the conformal anomaly parameter $\tildeα$
