Induction of biosynthesis of epicatechin in avocado suspension cells treated with an enriched CO2 atmosphere

PHYSIOlogicAL AND MOLECULAR PLANT PATHOLOGY 1996年第3期48卷 171-178页

Exposure to an atmosphere of 30% carbon dioxide caused increased levels of phenylalanine ammonia-lyase (PAL) activity in avocado cell suspension cultures. The carbon dioxide treatment also enhanced chalcone synthase activity by 30% and resulted in a 1 . 5-2 fold greater accumulation of epicatechin than in untreated cells. It was concluded that the level of epicatechin in avocado suspension cells can be increased by carbon dioxide, and this increase appears to be regulated by PAL and CHS activation.

STRONGLY FAULT SECURE PLAS AND TOTALLY SELF-CHECKING CHECKERS

引用

IEEE TRANSACTIONS ON COMPUTERS 1988年第7期37卷 863-867页

作者： MIN, YH LI, JT Inst. of Comput. Technol. Acad. Sinica Beijing China

A general approach is presented to the design of totally self-checking (TSC) programmable logic arrays (PLAs). A strongly fault secure (SFS) implementation is suggested for the functional PLA, which is shown to be SFS whenever the output is encoded by two-rail code. K-unit TSC checker (TSCC) element are defined to construct TSC checkers. The TSCC is very appropriate for the companion of the SLF PLA since a given input codeword set is sufficient for testing the TSCC. The minimum number of tests needed for a type-m two-rail code K -unit TSCC is 12m. This is a generalization of the fact that four test patterns are sufficient for testing an XOB parity checker tree. As an application, a novel design of a TSC comparator with an arbitrary number of inputs is presented

Tricontinuous Nanostructured Polymers via Polymerization-Induced Microphase Separation

引用

ACS MACRO LETTERS 2017年第11期6卷 1232-1236页

作者： Saba, Stacey A. Lee, Bongjoon Hillmyer, Marc A. Univ Minnesota Dept Chem Engn & Mat Sci 421 Washington Ave SE Minneapolis MN 55455 USA Univ Minnesota Dept Chem 207 Pleasant St SE Minneapolis MN 55455 USA

Nanostructured tricontinuous block polymers allow for the preparation of single-component materials that combine multiple properties. We demonstrate the synthesis of a mesoporous material from the selective orthogonal etching of a microphase-separated tricontinuous block polymer precursor. Using the synthetic approach of polymerization-induced microphase separation (PIMS), divinylbenzene (DVB) is polymerized from a mixture of poly(isoprene) (PI) and poly(lactide) (PLA) macro-chain transfer agents. In the PIMS process in situ cross-linking by the DVB arrests structural coarsening, resulting in a disordered block polymer morphology that we posit exhibits three nonintersecting continuous domains. Selective etching of the PI domains by olefin cross metathesis and PLA domains by hydrolytic degradation produces a mesoporous polymer with two independent pore networks arising from the different etch mechanisms.

作者： BHAT, C BISWAS, NN Dept. of Electr. Commun. Eng. Indian Inst. of Sci. Bangalore

Reports a new concept for transverse folding of programmable logic arrays (PLAs). With the new definitions for the compatibility and foldability of rows (columns) of a column-folded (row-folded) PLA, the transverse compatibility-cum-foldability matrix (TCFM) is plotted. From the TCFM, a transverse folding matrix (TFM) is found, from which the row (column) folding pairs and the resulting ordering of rows and columns are obtained

In this article, covert multi-channel communication against interference-assisted proactive detection is investigated in additive Gaussian white noise (AWGN) channel. We first analyze the detection performance for the warden and derive the covert constraints. Then, to maximize the average effective covert throughput (AECT) of the legitimate communicating parties, we establish an optimization problem by jointly optimizing the sub-channels number and transmit power. Analysis and numerical results show that selecting an appropriate number of sub-channels can improve the AECT against interference-assisted proactive detection comparison with single-channel schemes.

IEEE TRANSACTIONS ON NUCLEAR SCIENCE 1988年第1期35卷 300-302页

作者： ARAI, Y YASU, Y KEK National Laboratory Tsukuba Ibaraki Japan

A FASTBUS master module, 68K20FPI (68020 FASTBUS Processor Interface), which has the Motorola MC68020 32-bit microprocessor unit (MPU) and the MC68881 floating point coprocessor (FPCP), is presented. The 68K20FPI is intended to be used for a second-level trigger processor in a multiprocessor environment. It has a local-memory sunboard of 1-Mb static RAMs and a 512-kb ROM port, which are accessed from both the CPU and FASTBUS side. The SCSI (Small Computer Systems Interface) is adopted as a disk interface and also as a high-speed ( approximately 4-Mb/s) interface to other computers. The Ethernet interface is used for a communication line between the 68K20FPIs and a host computer. Two RS232C interfaces are used as terminal and host communication ports. A NIM level input and output are used for trigger purposes.< >

Configurable logic for digital communications: Some signal processing perspectives

For the past two decades software programmable digital signal processors and ASICs have provided hardware solutions for signal processing system designers. In comparatively recent times a new option has become available: field programmable gate arrays. FPGA-based DSP platforms allow the designer to realize a data path that exactly matches the required processing, while at the same time maintaining the flexibility of a software approach. This article presents an overview of some FPGA DSP applications. Several filter designs are presented, and the use of CORDIC arithmetic for constructing an FPGA carrier recovery loop is outlined. In addition to presenting design examples that can be realized using present-generation devices and tools, we take a brief look at how the dynamic reconfiguration aspect of certain FPGAs could be exploited in future-generation communication technologies.

PART is a system for PLA testing and design verification, intended to be properly interfaced with other existing tools to generate a comprehensive design environment. To this purpose, it provides several facilities, among which the capability of generating a fault population on the basis of layout information. PART aims at producing a very compact test set for all detectable crosspoint defects, using limited amounts of run time and storage. This is achieved by means of an efficient partitioning algorithm together with powerful heuristics. Test minimality is ensured by a simple procedure. In the present paper these are discussed, experimental results are given and a comparison with competing strategies is made.

Characterization and Prediction of Prolonged Air Leak After Pulmonary Resection: A Nationwide Study Setting Up the Index of Prolonged Air Leak

引用

ANNALS OF THORACIC SURGERY 2011年第3期92卷 1062-1068页

作者： Rivera, Caroline Bernard, Alain Falcoz, Pierre-Emmanuel Thomas, Pascal Schmidt, Aurelie Benard, Steve Vicaut, Eric Dahan, Marcel Haut Leveque Hosp CHU Bordeaux Dept Thorac Surg F-33604 Pessac France Bocage Hosp CHU Dijon Dijon France Civil Hosp CHU Strasbourg Strasbourg France North Hosp CHU Marseille Marseille France Steve Consultants Lyon France Fernand Widal Hosp Paris France Larrey Hosp CHU Toulouse Toulouse France

Background. The objective of this study was to better characterize prolonged air leak (PAL), defined as an air leak longer than 7 days, and to develop and validate a predictive model of this complication after pulmonary resection. Methods. All lung resections entered in Epithor, the French national thoracic database (French Society of Thoracic and Cardiovascular Surgery), were analyzed. Data collected between 2004 and 2008 (n = 24,113) were used to build the model using backward stepwise variable selection, and the 2009 data (n = 6,813) were used for external validation. The primary outcome was PAL. Results of the predictive model were used to propose a score: the index of PAL (IPAL). Results. Prevalence of PAL after pulmonary resection was 6.9% (n = 1,655) in the development data set. In the final model, 9 variables were selected: gender, body mass index, dyspnea score, presence of pleural adhesions, lobectomy or segmentectomy, bilobectomy, bulla resection, pulmonary volume reduction, and location on upper lobe. In the development data set, the C-index was 0.71 (95% confidence interval [CI], 0.70 to 0.72). At external validation, the C-index was 0.69 (95% CI, 0.66 to 0.72) and the calibration slope (ie, the agreement between observed outcomes and predictions) was 0.874 (<1). A score chart based on these analyses has been proposed. The formula to calculate the IPAL is the following: gender (F = 0;M = 4) - (body mass index-24) + 2 x dyspnea score + pleural adhesion (no = 0;yes = 4) + pulmonary resection (wedge = 0;lobectomy or segmentectomy = 7;bilobectomy = 11;bulla resection = 2;volume reduction = 14) + location (lower or middle lobe = 0;upper = 4). Conclusions. Surgeons can easily use the well-validated model to determine intraoperative preventive measures of PAL. (Ann Thorac Surg 2011;92:1062-8) (C) 2011 by The Society of Thoracic Surgeons
