The mass of the [Lambda]c(2625)+, relative to the [Lambda]+c mass, is already relatively well known, but the large Belle data sample allows for a more precise measurement. No intrinsic width of the [Lambda]c(2625)+ has yet been measured, and the current upper limit [Gamma]
Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon[Lambda][sub c][sup+] into pK[sup -][pi][sup+][pi][sup 0], p[bar K][sup 0], p[bar K][sup 0][pi][sup+][pi][sup -], and p[bar K][sup 0][pi][sup 0], all measured relative to pK[sup -][pi][sup+]. The relative branching fractions are 0.67[+-] 0.04[+-] 0.11, 0.46[+-] 0.02[+-] 0.04, 0.52[+-] 0.04[+-] 0.05, and 0.66[+-] 0.05[+-] 0.07 respectively.
The confirmation of the Cabibbo-suppressed charm baryon decay mode?{sub c} → p?+?− is reported. All data analyzed are from SELEX, a fixed target experiment at Fermilab that took data during 1996 and 1997, mainly with a 600 GeV/c?− beam. The branching ratio of the Cabibbo-suppressed decay mode?{sub c}+ → p?+?− relative to the Cabibbo-favored mode?{sub c}+ → pK−?+ is measured to be:?(?{sub c}+ → p?+?−)/?(?{sub c}+ → pK−?+) = 0.103 ± 0.022.
Using data recorded by the CLEO-II detector at CESR, we report new measurements of the branching fractions for the decays of the charmed baryon?{sub c} into pK−?+?°, p{bar K}°, p{bar K}°?+?−, and p{bar K}°?°, all measured relative to pK−?+. The relative branching fractions are 0.67 ± 0.04 ± 0.11, 0.46 ± 0.02 ± 0.04, 0.52 ± 0.04 ± 0.05, and 0.66 ± 0.05 ± 0.07 respectively.
Recently a T = 1 resonance in the [Lambda][pi] system called Y*1 has been observed with a mass of 1385 Mev. Two types of resonances have been predicted that might relate this observation to other elementary-particle interactions: (1) P 3/2 resonances in the [Lambda][pi] and [Sigma][pi] systems predicted by global symmetry corresponding to the (3/2, 3/2) resonance of the [pi]N system; (2) a spin-1/2 Y-[pi] resonance resulting from a bound state in the KN system. The position and width of the observed Y*1 resonance agree with both theories, but since the spin and parity have not yet been determined, it is impossible at present to distinguish between the two theoretical interpretations.
The handbook has been composed on the basis of processing, systematization and classification of the results of a great number of investigations published at different time. The essential part of the book is the outcome of investigations carried out by the author. The present edition of this handbook should assist in increasing the quality and efficiency of the design and usage of indutrial power engineering and other constructions and also of the devices and apparatus through which liquids and gases move.

This volume contains the lectures and communications presented at the NATO Advanced Research Workshop (NATO ARW 900857) which was held May 5-10, 1991 at McMaster University, Hamilton, Ontario, Canada. A scientific commitee made up of P.P. Lambropoulos (USC & Crete), P.8. Corkum (NRC, Ottawa), and H. B. vL. van den Heuvell (FOM, Amsterdam) guided the organizers, A.D. Bandrauk (Sherbrooke) and S.C. Wallace (Toronto) in preparing a programme which would cover the latest advances in the field of atom and molecule laser interactions. Since the last meeting held in July 1987 on "Atomic and Molecular Processes with Short Intense Laser Pulses", NATO ASI vol 1718 (Plenum Press 1988), considerable progress has been made in understanding high intensity effects on atoms and the concomitant coherence effects. After four years, the emphasis is now shifting more to molecules. The present volume represents therefore this trend with four sections covering the main interests of research endeavours in this area: i) Atoms in Intense Laser-Fields ii) Molecules in Intense Laser Fields iii) Atomic Coherences iv) Molecular Coherences The experience developed over the years in multiphoton atomic processes has been very useful and is the main source of our understanding of similar processes in molecules. Thus ATI (above threshold ionization) has been found to occur in molecules as well as a new phenomenon, ATD (above-threshold dissociation). Laser-induced avoided crossings of molecular electronic surfaces is also now entering the current language of high intensity molecular processes.
Helps Students Understand Mathematical Programming Principles and Solve Real-World Applications Supplies enough mathematical rigor yet accessible enough for undergraduates Integrating a hands-on learning approach, a strong linear algebra focus, MapleTM software, and real-world applications, Linear and Nonlinear Programming with MapleTM: An Interactive, Applications-Based Approach introduces undergraduate students to the mathematical concepts and principles underlying linear and nonlinear programming. This text fills the gap between management science books lacking mathematical detail and rigor and graduate-level books on mathematical programming. Essential linear algebra tools Throughout the text, topics from a first linear algebra course, such as the invertible matrix theorem, linear independence, transpose properties, and eigenvalues, play a prominent role in the discussion. The book emphasizes partitioned matrices and uses them to describe the simplex algorithm in terms of matrix multiplication. This perspective leads to streamlined approaches for constructing the revised simplex method, developing duality theory, and approaching the process of sensitivity analysis. The book also discusses some intermediate linear algebra topics, including the spectral theorem and matrix norms. Maple enhances conceptual understanding and helps tackle problems Assuming no prior experience with Maple, the author provides a sufficient amount of instruction for students unfamiliar with the software. He also includes a summary of Maple commands as well as Maple worksheets in the text and online. By using Maple’s symbolic computing components, numeric capabilities, graphical versatility, and intuitive programming structures, students will acquire a deep conceptual understanding of major mathematical programming principles, along with the ability to solve moderately sized real-world applications. Hands-on activities that engage students Throughout the book, student understanding is evaluated through "waypoints" that involve basic computations or short questions. Some problems require paper-and-pencil calculations; others involve more lengthy calculations better suited for performing with Maple. Many sections contain exercises that are conceptual in nature and/or involve writing proofs. In addition, six substantial projects in one of the appendices enable students to solve challenging real-world problems.
