Subjects: subject: 020 Bibliotheks- und Informationswissenschaft

description: Universitäten sind nicht nur wissensintensive Einrichtungen, sondern strukturell-immanent mit Wissen verbunden. Sie produzieren, formalisieren und verbrauchen Wissen und Information. Kommerzielle Wirtschaftsunternehmen mit einem noch nicht annähernd so hohen Wissenspotenzial, setzen mit großer Selbstverständlichkeit Knowledge Management ein, um das Kapital ihrer Mitarbeiter zu sichern und zu nutzen. Universitäten hingegen beginnen erst zögerlich mit dem Einsatz von Knowledge Management, obwohl sie ein riesiges Potenzial dazu besitzen. Als Einsatzbereiche werden Lehre, Forschung und die Verwaltung (mit allen Prozessen im Personal- und Ressourcenmanagement) diskutiert. Die Bibliothek und ihre Mitarbeiter sollten dabei unbedingt beim Einsatz von Knowledge Management in Universitäten beteiligt werden: Informationsspezialisten sind In der Lage Daten aufzubereiten, zu strukturieren,' zu bewerten und zur Verfügung zu stellen, während die Bibliothek einer Universität der Ort der Interdisziplinarität, des sozialen Austauschs und der allgemeinen Kommunikation ist. Bibliotheken und Bibliothekare werden als kompetente Partner für die Einführung von KM in Universitäten vorgestellt.

description: A direct and high-precision measurement of the mass difference of ¹²³Te and ¹²³Sb has been performed with the Penning-trap mass spectrometer SHIPTRAP using the recently introduced phase-imaging ioncyclotron-resonance technique. The obtained mass difference is 51.912(67) keV/c². Using the masses of the neutral ground states and the energy difference between the ionic states an effective half-life of ¹²³Te has been estimated for various astrophysical conditions. A dramatic influence of the electron capture process on the decay properties of ¹²³Te in hot stellar conditions has been discussed.

description: Small and medium enterprises generally employ the use of custom developed quoting programs to bid on goods and services. Custom bid programs (e.g., Microsoft Excel) are used to capture the company-specific costs of production. The inputs of variable costs, such as machine rate and scrap rate, are critical to get correct (Brassington & Pettitt, 2013); however, companies often rely on educated guesses and industry expertise to quote packaging products to end-users. Due to the guesswork involved there can be a financial difference between the quoted costs and actual costs. This variance is often the cause of significant lost dollars. Price, if not determined correctly, could negatively impact both the company’s and the product’s profitability (Helna, 2020). Predictive analytics can be used to support quoting activities by providing a future value based on previous job performance. The purpose of the present study is to identify whether predictive analytics can be used to predict machine rate and scrap rate to give more accuracy to quoting estimation.

description: The synthesis of diastereoisomeric [1,2-bis(2-hydroxyphenyl)ethylenediamine]dichloroplatinum(II) complexes, DL-3-PtCl2 and meso-3-PtCl2, and their evaluation on the hormone-independent, human MDA-MB231 breast cancer cell line, on the cisplatin-sensitive and -resistant L1210 leukemia cell line, on the cisplatin-resistant human NIH:OVCAR 3 ovarian cancer cell line, on the P-388 leukemia of the mouse and on the cisplatin-sensitive and -resistant Ehrlich ascites tumor of the mouse are described. On all tumor models DL-3-PtCl2 produces a marked inhibitory effect. The diastereoisomer meso-3-PtCl2 is less active and more toxic. It is striking that DL-3-PtCl2 leads to a pronounced inhibition of all cisplatin-resistant tumors. At non-toxic concentrations DL-3-PtCl2 produces cytocidal effects on the NIH:OV-CAR 3 cell line. Therefore DL-3-PtCl2 is of interest for further evaluation for the therapy of ovarian cancer.

description: Experiments on the P 388 D1 cell line (48 h exposure) demonstrate that [1,2-bis-(fluorophenyl)ethylenediamine]platinum(II) complexes are comparably active on the cell number and 3H-thymidine incorporation, irrespective of the position of the fluorine atom (ortho, meta, or para) and the nature of the "leaving group" (Cl- or H2O). However, the compounds of the R,R/S,S series are more active than those of the R,S series and comparable to cisplatin. In the "tumor colony forming assay" the R,R/S,S configurated compounds are about ten times as active as cisplatin. The R,R/S,S configurated diaqua[1,2-bis(4-fluorophenyl)ethylenediamine]platinum(II) salts reach their half maximum effect more readily (t1/2 approximately equal to 1.6 h) than their R,S configurated analogues (t1/2 approximately equal to 20 h). A time limited contact of the cells with R,R/S,S configurated diaqua[1,2-bis(4-fluorophenyl)ethylenediamine]platinum(II) salts (-1h) leads to a similar inhibition like a permanent drug exposure indicating a fast uptake of the complex by the tumor cell. In experiments on the Ehrlich ascites tumor of the mouse and on the L 1210 leukemia cell line R,R/S,S-[1,2-bis(4-fluorophenyl)ethylenediamine]dichloroplatinum(II) turns out to be equipotent with cisplatin.

description: In this paper we describe the microcomputer-aided determination of cell proliferation kinetics and doubling times utilizing a crystal violet assay and a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide assay in microtitration plates. The analysis of spectrophotometric data provides the doubling times at any time of incubation. Plots of doubling time versus time of incubation give reproducible information on the exact duration of the logarithmic growth phase. This method is applicable to anchorage-dependent as well as anchorage-independent cells when colorimetric or fluorometric data are accessible.

description: Cisplatin, raceme-diaqua[1,2-bis(4-fluorophenyl)ethylenediamine]platinu m(II) sulfate (compound I), meso-diaqua[1,2-bis(4-fluorophenyl)ethylenediamine]-platinum(II) sulfate (compound II), and meso-diaqua[1,2-bis(2,6-dichloro-4- hydroxyphenyl)ethylenediamine]platinum(II) sulfate (compound III) were compared with regard to their effect on the MCF-7 breast cancer cell line in vitro. At equimolar concentrations (5 microM), cisplatin, compound I, and compound II were equiactive after 231 h drug exposure, whereas compound III was ineffective. Although compounds I and II showed markedly greater inactivation than did cisplatin after 6 h incubation with culture medium, compound I (but not compound II) exhibited antitumor activity equivalent to that of cisplatin when cells were exposed to the drugs for 6 h. Platinum measurements by neutron-activation analysis revealed that compound I was selectively and rapidly accumulated by MCF-7 cells, resulting in a high degree of DNA platination within the first few hours of drug exposure. However, when the drug-exposure period was long enough, platinum enrichment was not reflected in an overall difference in the cytotoxicity of compound I vs cisplatin. Nevertheless, compound I should be superior to cisplatin in vivo, provided that effective plasma levels can be maintained for about 6 h.

description: Conventionally in vitro cytotoxicity assays are performed as single-end-point determinations. To compensate for the diversity of growth rates among different cell lines in this report we describe a computerized kinetic chemosensitivity assay based on quantification of biomass by staining cells with crystal violet. As a prerequisite four human breast cancer cell lines (MDA-MB-231, MCF-7, T-47-D and ZR-75-1) were characterized with regard to oestrogen and progesterone receptor content, modal chromosome number and proliferation kinetics depending on the number of passages in culture. With prolonged time in culture for ZR-75-1 exposed to various concentrations of cisplatinum a dose-related increase in drug effect was observed. Owing to a correction of the T/C values for the initial cell mass (at the time when drug is added) a sharp distinction between cytostatic and cytocidal drug effects becomes obvious in plots of corrected T/C values versus time of incubation. The influence of the untreated control on the corrected T/C values and possible time courses of theoretical inhibition profiles (reflecting cytostatic, transient cytotoxic or cytocidal drug effects as well as development of resistance) and their relationship to the corresponding growth curves of drug-treated cells are discussed. Chemosensitivity assays with diethylstilbestrol dipropionate, tamoxifen, melphalan, cisplatinum, vinblastine, Adriamycin and 5-fluorouracil prove the theoretical considerations to be true for MDA-MB-231, MCF-7, T-47-D and ZR-75-1 human breast cancer cell lines in practice.

description: Optical Parametric Oscillators (OPOs) have wide applications in quantum optics for generating squeezed states and developing advanced technologies. When the phase or/and the amplitude of the pumping field for an OPO have fluctuations due to fault signals, time-varying uncertainties will be introduced in the dynamic parameters of the system. In this paper, we investigate how to design a fault-tolerant $H^\infty$ controller for an OPO with a disturbance input and time-varying uncertainties, which can achieve the required $H^\infty$ performance of the quantum system. We apply robust $H^\infty$ control theory to a quantum system, and design a passive controller and an active controller based on the solutions to two Riccati equations. The passive controller has a simple structure and is easy to be implemented by using only passive optical components, while the active quantum controller may achieve improved performance. The control performance of the proposed two controllers and one controller that was designed without consideration of system uncertainties is compared by numerical simulations in a specific OPO, and the results show that the designed controllers work effectively for fluctuations in both the phase and amplitude of the pumping field.

description: In the present study the establishment and characterization of a new oxyphilic papillary thyroid carcinoma cell line--ONCO-DG1- is given. With immunohistological, histochemical and flow cytometric methods, ONCO-DG 1 cells revealed features of epithelial differentiation. Furthermore the cells formed von Kossa-positive deposits resembling psammoma bodies in monolayer and spheroid culture until late passages. The tumor cell line is now in the 40th subculture. Because of the ability to form multicellular tumor spheroids (MCTS), this cell line is a good model for examining the interaction between thyroid tumor cells and confluent human endothelial cells on extracellular matrix in vitro. It is also suitable for xenotransplantation studies, because it is tumorigenic in NMRI nude mice in vivo.

description: Elevated hydrostatic pressure has been shown to affect the growth rate of the thermophilic methanobacterium Methanococcus thermolithotrophicus without extending its temperature range of viability. Analysis of the cell inventory after approximately 10 h of incubation at 65 degrees C and 50 MPa (applying high-pressure liquid chromatography and two-dimensional gel electrophoresis) proved that pressure induces alterations in the protein pattern and the amino acid composition of the total cell hydrolysate. Gels showed that after pressurization a series of (basic) proteins with a molecular mass in the range of 38 and 70 kilodaltons occurs which is not detectable in cells grown at normal atmospheric pressure. The question of whether the observed alterations are caused by the perturbation of the balance of protein synthesis and turnover or by the pressure-induced synthesis of compounds analogous to heat shock proteins remains unanswered.

description: We apply a three-dimensional (3D) approach to investigate the quasi-stationary states of well-deformed $α$-emitters. With a splitting of the anisotropic 3D potential into internal and external parts at a separation surface, the 3D $α$-cluster decay width is determined by the initial wave function of a true bound state of an anisotropic harmonic oscillator potential and a non-resonance scattering wave function of Coulomb potential. Substantial difference between the 1D and 3D decay width is found for typical $α$-emitters with large quadrupole and hexadecapole deformations.

description: High-pressure, high-temperature investigations on thermophilic microorganisms that grow on hydrogen or other gaseous substrates require instrumentation which provides sufficient substrate for cell proliferation up to 2 x 10 to 3 x 10 cells per ml under isothermal and isobaric conditions. To minimize H(2) leakage and to optimize reproducibility at high pressure and high temperature, 10-ml nickel tubes with a liquid/gas ratio of 1:2 were used in a set of autoclaves connected in series. By applying a hydraulic pump and a 2.5-kW heating device, fast changes in temperature (up to 400 degrees C) and pressure (up to 400 MPa) can be accomplished within less than 10 min. To quantify bacterial growth, determinations of cell numbers per unit volume yielded optimum accuracy. Preliminary experiments with the thermophilic, methanogenic archaebacterium Methanococcus thermolithotrophicus showed that bacterial growth depends on both temperature and pressure. At the optimum temperature, increased hydrostatic pressure up to 50 MPa enhanced the growth yield; at a pressure of >75 MPa, cell lysis dominated. Changes in cell proliferation were accompanied by changes in morphology.

description: Quantum entanglement plays a fundamental role in quantum computation and quantum communication. Feedback control has been widely used in stochastic quantum systems to generate given entangled states since it has good robustness, where the time required to compute filter states and conduct filter based control usually cannot be ignored in many practical applications. This paper designed two control strategies based on the Lyapunov method to prepare a class of entangled states for qubit systems with a constant delay time. The first one is bang bang like control strategy, which has a simple form with switching between a constant value and zero, the stability of which is proved. Another control strategy is switching Lyapunov control, where a constant delay time is introduced in the filter-based feedback control law to compensate for the computation time. Numerical results on a two qubit system illustrate the effectiveness of these two proposed control strategies.

This setting is particularly relevant for domain specific RE where no annotated dataset is available and for open-domain RE where the types of relations are a priori unknown. Although recent approaches achieve promising results, they heavily depend on hyperparameters whose tuning would most often require labeled data. To mitigate the reliance on hyperparameters, we propose PromptORE, a ''Prompt-based Open Relation Extraction'' model. We adapt the novel prompt-tuning paradigm to work in an unsupervised setting, and use it to embed sentences expressing a relation. We then cluster these embeddings to discover candidate relations, and we experiment different strategies to automatically estimate an adequate number of clusters. To the best of our knowledge, PromptORE is the first unsupervised RE model that does not need hyperparameter tuning. Results on three general and specific domain datasets show that PromptORE consistently outperforms state-of-the-art models with a relative gain of more than 40% in B 3 , V-measure and ARI. Qualitative analysis also indicates PromptORE's ability to identify semantically coherent clusters that are very close to true relations.

description: The enantiomeric [1,2-bis(2-hydroxyphenyl)-ethylenediamine]dichloroplatinum(II) complexes were synthesized and their configuration assessed. A preliminary test in the cisplatin-resistant human NIH:OVCAR-3 ovarian cancer cell line, which was previously characterized by its sensitivity against several therapeutically used drugs, showed that both enantiomers produce cytocidal effects in a concentration of 2.5 microM. A difference between the enantiomers became evident from the faster onset of cytocidal activity of the S,S-configurated compound.

description: The diastereoisomeric dichloro-[1-(2-, 3- and 4-hydroxyphenyl)-2-phenylethylenediamine]platinum(II) complexes were tested on two human ovarian cancer cell lines NIH: OVCAR-3 and SK-OV-3, both resistant against cisplatin. Dichloro-[threo-1-(3-hydroxyphenyl)-2-phenylethylenediamine]platinum(II) (threo-5-PtCl2) proved to be the most active representative of the new series, producing cytocidal effects at a concentration range of 2.5 to 5.0 microM on the NIH: OVCAR-3 cell line. On the more resistant SK-OV-3 cell line, threo-5-PtCl2 was only moderately active, while in combination with BSO, a GSH level lowering compound, threo-5-PtCl2 showed a strong synergistic effect.

description: AIM: Sensors incorporated in lab-on-a-chip (LOC) platforms permit in situ measurements of analytes over time [1]. LOC approach with integrated impedimetric sensor has been used in this study aiming to develop a sensor for biomass estimation during cell cultivation in the novel, cost-effective microbioreactor (MBR). Interaction between cells and electromagnetic radiation in different frequency ranges enables detection and characterization of various cellular parameters. In the radio-frequency (RF) range, viable cells are polarizable and act as dipoles, hence the number of cells directly influences the dielectric permittivity of measured impedance [2]. In that sense, an impedimetric approach allows sensing the cell concentration and therefore biomass. Additionally, the LOC approach enables good control and collection of data relevant for the cultivation process [3]. METHODS: Cost-effective technologies of MBR and sensor fabrication are presented, as well as their integration and testing results obtained with MRC-5 cells used as model adherent cells. RESULTS: Developed impedimetric sensor in MBR has been able to detect number of cells i.e. biomass, as well as all the phases in batch cell cultivation over 96 h - lag, exponential, stationary, and death phase. CONCLUSION: By combining biocompatible and transparent materials, the LOC system provides a basis that allows additional integration of electrodes, sensors, or optical components, and has a potential for the rapid production of low-cost and reliable MBRs that can be used in cultured meat research. Impedance-based sensing is a good approach for biomass monitoring in MBRs.

description: Temperature and hydrostatic pressure are essential in determining the assemblage of species in their specific biotopes. To evaluate the effect of high pressure on the range of viability of thermophiles, the pressure and temperature dependence of the growth of the methanogenic archaebacterium Methanococcus thermolithotrophicus was investigated. High pressure up to 50 MPa enhanced the growth rate without extending the temperature range of viability. The optimum temperature remained unaltered (65 degrees C). Beyond 50 MPa, cell lysis predominated over cell proliferation. Destabilization was also observed at temperatures below and above the optimum growth temperature (<60 degrees C, >/=70 degrees C) and at low substrate concentrations.

description: The stereoisomeric [1,2-bis(2-hydroxyphenyl)ethylenediamine]dichloroplatinum(II) complexes were thoroughly tested on the cisplatin-resistant human NIH:OVCAR-3 ovarian cancer cell line. The racemate and its enantiomers produced cytocidal effects at a concentration of 2.5 microM (incubation time 256 h). The meso form, however, was merely cytostatically active. Differences between the enantiomers became evident after a short drug incubation time (1 h) followed by an incubation in drug-free medium (243 h). The S,S-configurated enantiomer (-)-3-PtCl2 proved to be the most active compound. To achieve cytocidal effects concentrations of 2.5-5.0 microM and incubation times of about 3 h were necessary for (-)-3-PtCl2. This compound is also sufficiently stable under test conditions as shown by the preincubation in cell-free medium for 3 h. These results and the augmentation of its antitumor activity by buthionine sulfoximine recommend the further preclinical development of (-)-3-PtCl2 for clinical use.

description: This paper proves three theorems on growth and competition in a standard increasing variety endogenous growth model and draws conclusions for second-best competition policies. First, no growth may be better than some growth, since modest positive growth potentially requires sizeable static welfare losses. Second, the economy may converge to a steady state with zero growth, even though another (saddle-point stable) steady state with positive growth exists if the initial share of "cheap" competitive markets is sufficiently high, as this implies a relatively low demand for "expensive" innovative goods. Third, such a "no-growth trap" may happen in a world economy made up of several countries engaged in free trade with each other. As for competition policy, this implies that growth-enhancing policies maybe misguided and that quick deregulation as well as quick trade liberalization can lead to stagnation in the long term. In diesem Papier werden drei Theoreme zu Wachstum und Wettbewerb in einem Standard-Varietäten-Wachstumsmodell bewiesen und Rückschlüsse für zweitbeste Wettbewerbspolitiken gezogen. Erstens kann kein Wachstum besser sein als geringes Wachstum, weil auch geringe positive Wachstumsraten möglicherweise beträchtliche statische Wohlfahrtsverluste erfordern. Zweitens kann die Ökonomie gegen einen Steady State mit Null-Wachstum konvergieren obwohl ein anderer (sattelpunkt-stabiler) Steady State mit positivem Wachstum existiert, wenn der anfängliche Anteil "billiger", kompetitiver Märkte hinreichend groß ist, da dies eine relativ geringe Nachfrage nach "teueren", innovativen Produkten impliziert. Drittens kann eine solche "Null-Wachstumsfalle" in einer Welt-Ökonomie auftreten, die aus mehreren Ländern besteht, die untereinander durch freien Handel verbunden sind. Für die Wettbewerbspolitik folgt, dass wachstumsfördernde Maßnahmen möglicherweise fehlgeleitet sein können und schnelle Deregulierung und schnelle Handelsliberalisierung potentiell zu langfristiger Stagnation führen können.

description: Augmentation techniques and sampling strategies are crucial in contrastive learning, but in most existing works, augmentation techniques require careful design, and their sampling strategies can only capture a small amount of intrinsic supervision information. Additionally, the existing methods require complex designs to obtain two different representations of the data. To overcome these limitations, we propose a novel framework called the Self-Contrastive Graph Diffusion Network (SCGDN). Our framework consists of two main components: the Attentional Module (AttM) and the Diffusion Module (DiFM). AttM aggregates higher-order structure and feature information to get an excellent embedding, while DiFM balances the state of each node in the graph through Laplacian diffusion learning and allows the cooperative evolution of adjacency and feature information in the graph. Unlike existing methodologies, SCGDN is an augmentation-free approach that avoids "sampling bias" and semantic drift, without the need for pre-training. We conduct a high-quality sampling of samples based on structure and feature information. If two nodes are neighbors, they are considered positive samples of each other. If two disconnected nodes are also unrelated on $k$NN graph, they are considered negative samples for each other. The contrastive objective reasonably uses our proposed sampling strategies, and the redundancy reduction term minimizes redundant information in the embedding and can well retain more discriminative information. In this novel framework, the graph self-contrastive learning paradigm gives expression to a powerful force. SCGDN effectively balances between preserving high-order structure information and avoiding overfitting. The results manifest that SCGDN can consistently generate outperformance over both the contrastive methods and the classical methods.

description: A number of methoxy-substituted 7,11b,12,13-tetrahydro-6H-dibenzo-[a,f]quinolizines with short alkyl groups in position 6 or 12 were synthesized by the Bischler-Napieralski reaction using the appropriate starting material followed by a second ring closure reaction involving a base-generated benzyne intermediate. The methoxy functions in positions 2 or 3 and 9 were cleaved with BBr3 and the free hydroxy groups converted into the acetates. The enantiomers of two of these derivatives were separated by liquid chromatography on triacetylcellulose. Compounds with alkyl substituents bind strongly to the estrogen receptor except those with a cis-orientation at the central ring connection. The RBA values ranged from 2.2-10.8 (17 beta-estradiol: RBA = 100). There was no major difference in binding between the (+) and (-)-enantiomers. The 3,9-diacetoxy-6-alkyl derivatives also showed binding affinity for the progesterone receptor (RBA: 1.2-3.1). The 2,9-diacetoxydibenzoquinolizines trans-61 and -6m with ethyl and propyl respectively in position 12 strongly inhibited the growth of hormone-sensitive MCF-7 breast cancer cells at concentrations of 10(-6) M and higher but were inactive in hormone-independent MDA-MB 231 breast cancer cells. Preliminary tests with hormone-dependent MXT mouse mammary tumors as model showed that these compounds have also antineoplastic activity in vivo. Derivative trans-61 at a dose of 20 mg/kg body weight, administered 3 times/week, inhibited the growth of these tumors by 78% (tamoxifen: 76% inhibition). Studies on the estrogenic and antiestrogenic properties of these agents in mice revealed that they are mixed agonists/antagonists with strong antiestrogenic activity at low doses but significant estrogenic effects at higher doses.
