TESTCHIP: a chip for weighted random pattern generation,evaluation, and test control

In self-testable circuits, additional hardware is incorporated for generating test patterns and evaluating test responses. A built-off test strategy is presented which moves the additional hardware to a programmable extra chip. This is a low-cost test strategy in three ways: (1) the use of random patterns eliminates the expensive test-pattern computation; (2) a microcomputer and an ASIC (application-specific IC) replace the expensive automatic test equipment; and (3) the design for testability overhead is minimized. The presented ASIC generates random patterns, applies them to a circuit under test, and evaluates the test responses by signature analysis. It contains a hardware structure that can produce weighted random patterns corresponding to multiple programmable distributions. These patterns give a high fault coverage and allow short test lengths. A wide range of circuits can be tested as the only requirement is a scan path and no other test structures have to be built in

In this paper, denoted a continuous function from [0,1]² into [0,1] by f, we consider the iterative process:

Some Experiences of Using Different Analytical Methods in Screening for Oil and Protein Content in Rapeseed

In this study some analytical methods, which have been used in oil crop breeding, are compared from the point of view of plant breeding. For oil content determination a gravimetric method, NMR and NIR have been used. Protein content has been determined by the classical Kjeldahl technique, by the Biuret method and by NIR. The results indicate that the NIR spectroscopy is specially useful in screening breeding materials. This method enables the breeder to select for several quality characters simultaneously at a high speed and at a low cost. Since NIR spectroscopy is nondestructive, the same seed lot can be used for analysis and planting. Thus it is possible to select on a large scale for single plants.     

Heat capacities of polyethylene and linear fluoropolymers

Heat capacities at constant pressure, C_p, and at constant volume C_v, were calculated with the help of normal mode frequency spectra and compared to experimental data for crystalline or semicrystalline polyethylene, poly(vinyl fluoride), poly(vinylidene fluoride), polytrifluooroethylene and poly(tetrafluoroethylene). A calculation scheme using a Tarasov function for 2N skeletal vibrational modes and an approximation of the residual 7N normal modes from known data on polyethylene and polytetrafluoroethylene is developed for all homologous, linear fluoropolymers. N is the number of carbon backbone atoms of the repeating unit. Calculations can be carried out over the whole temperature range 0 K to melting. For the two theta temperatures and the constant A₀ used for C_v to C_p conversion, fluorine-concentration dependent curves are given. The relations are expected to hold also for copolymers and blends of intermediate fluorine contents. Recommended experimental (data bank) heat capacities agree to ±2.5% with the calculations.     

A study of sulfur bridges in filled natural rubber vulcanizates by pyrolysis gas chromatography with flame-photometric detection

Natural rubber vulcanizates of two formulations, with sulfur/N-cyclohexyl-2-benzothiazolesulfenamide (CBS) and tetramethylthiuram disulfide (TMTD), respectively, were analyzed by pyrolysis gas chromatography. A sulfur-selective flame-photometric detector was utilized. The main pyrolysis products were identified as CS₂ and some thiophenes. The yields of the pyrolysis products from the two types of rubber were very different. The yields also varied with the curing time of the rubbers.     

Dystopie und Methode: zur fiktionalen Verhandlung moralischer Überzeugungen in der Bioethik

Definition of the problem

The role of stories is well established in the traditions of narrative ethics and casuistry. However, from a methodological point of view, the inclusion of fictional works in moral deliberation remains yet unanswered. The paper explains the potential of dystopias for bioethics by means of selected examples and a critical reconstruction and expansion of existing approaches.

Arguments

By means of literary theories, it is proposed to include moral beliefs that motivate dystopias in coherent reflection and reasoning procedures. Furthermore, dystopia’s potential through socioculturally dense scenarios, a contemporary-historical context, and a sensitization to the moral relevance of language for bioethical research are systematically presented.

Conclusion

The methodological considerations provide, on the one hand, practical points of reference for didactic approaches and, on the other hand, for public deliberation. However, the analysis also shows that dystopias introduce their own moral positions beyond a mere illustration or warning.

     

Leveraging Values in Global Organizations: Premises,Paradoxes and Progress

In this focused issue on the theme of “Leveraging Values in Global Organizations”, we highlight several prevalent themes on national, organizational and individual values in the literature. We argue that many premises in the literature have been accepted as fact; yet there are still many avenues open to exploration. We present several paradoxes that are often overlooked or lead to inconsistencies in the literature on values. The five articles in this focused issue address these premises and paradoxes, presenting new challenges and opportunities, providing progress and paving the way for future research on leveraging values in global organizations. The selected articles explore values with respect to international alliances and subsidiaries of multinational organizations at the organizational level, among global managers at the group level, and among employees and inpatriates at the individual level of analysis. We trust that readers of this issue will agree that the articles provide novel insights into key issues in the established, yet dynamic, field of research on values in the context of global organizations.     

Treatment of pulmonary hypertension with inhaled nitric oxide during hepatic transplantation in an adolescent: reversibility of pulmonary hypertension after transplantation

Accusations of rape or sexual harassment are currently very high-profile in the military. This article discusses rape allegations in the military legal system from a psychiatric perspective. The original definition of "rape trauma syndrome" and subsequent psychiatric thinking about the diagnosis are briefly outlined. Common reactions seen in military victims in this era are described. A prototypical military case is presented. An adequate evaluation of an alleged victim is outlined. Credentials and preparation of an expert witness are also briefly discussed, with cautions about the use of expert testimony in cases of alleged sexual assault and rape trauma syndrome.
