We prove that if f (x) = n−1 ak xk is a polynomial with no cyclotomic k=0 factors whose coeﬃcients satisfy ak ≡ 1 mod 2 for 0 ≤ k 1 + log 3 , 2n resolving a conjecture of Schinzel and Zassenhaus [21] for this class of polynomials. More generally, we solve the problems of Lehmer and Schinzel and Zassenhaus for the class of polynomials

• ### HOLLYWOOD WALK OF FAME: Nomination for 2014 Selection

To track the dynamic of continuity and change since 1960, it’s conventional to start by looking at the ﬁlm industry. As usually recounted, the indus- try’s fortunes over the period display a darkness-to-dawn arc that might satisfy a scriptwriter of epic inclinations.We now have several nuanced ver- sions of this story, so I’ll merely point out some major turning points. 1 The appendix provides a year-by-year chronology.

satisfy boundary conditions at more than one value of the independent variable, the resulting problem is called a two point boundary value problem. As the terminology indicates, the most common case by far is where boundary conditions are supposed

• ### ON BOUNDARY VALUE PROBLEMS FOR SECOND-ORDER DISCRETE INCLUSIONS ´ PETR STEHLIK AND CHRISTOPHER C.

ON BOUNDARY VALUE PROBLEMS FOR SECOND-ORDER DISCRETE INCLUSIONS ´ PETR STEHLIK AND CHRISTOPHER C. TISDELL Received 8 October 2004 We prove some existence theorems regarding solutions to boundary value problems for systems of second-order discrete inclusions. For a certain class of right-hand sides, we present some lemmas showing that all solutions to discrete second-order inclusions satisfy an a priori bound. Then we apply these a priori bounds, in conjunction with an appropriate ﬁxed point theorem for inclusions, to obtain the existence of solutions.

EXISTENCE OF A POSITIVE SOLUTION FOR A p-LAPLACIAN SEMIPOSITONE PROBLEM MAYA CHHETRI AND R. SHIVAJI Received 30 September 2004 and in revised form 13 January 2005 We consider the boundary value problem −∆ p u = λ f (u) in Ω satisfying u = 0 on ∂Ω, where u = 0 on ∂Ω, λ 0 is a parameter, Ω is a bounded domain in Rn with C 2 boundary ∂Ω, and ∆ p u := div(|∇u| p−2 ∇u) for p 1. Here, f : [0,r] → R is a C 1 nondecreasing function for some r 0 satisfying f...

• ### WORKING PAPER SERIES NO 1457 / AUGUST 2012: EXCESSIVE BANK RISK TAKING AND MONETARY POLICY

This has given rise to concerns about oil palm expansion contributing to the loss of biodiversity, greenhouse gas emissions, and social conflict due to a fail- ure to recognize local land rights.With expected further increases in palm oil demand, directing plantation expansion away from standing forest toward degraded grassland areas will be important. Estimates suggest that the area available under these degraded areas is at least double what is needed to satisfy increased demand over the next decade.

• ### Theory-W Software Project Management: Principles and Examples

Can these two images be reconciled? How to do we blend Zen and the underlying wisdom it represents with project management and its quest for satisfying people and organizations with valuable outcomes within time and cost constraints? Blending Zen and project management enables us to more effec- tively manage projects to get the results we want, when we want them, for the price we expect to pay. This is the outer work—perfecting the form and perfecting its results.

• ### Alternative Technologies for Biofuels Production in Kraft Pulp Mills—Potential and Prospects

With combined power and heat generation (cogeneration) the waste heat incurred during engine operation is recovered and utilized to satisfy thermal system process requirements for low- grade steam and/or hot water. In many cases this utilization of waste heat results in overall systems of efficiencies of up to 90+% (thermal + electrical). This efficient form of energy conversion is able to achieve primary energy savings of about 40% using gas engine cogeneration systems, compared with conventional separate power and heat generation.

• ### Báo cáo khoa học: "COMPUTATIONAL COMPLEXITY IN TWO-LEVEL MORPHOLOGY"

Morphological analysis must take into account the spelling-change processes of a language as well as its possible configurations of stems, affixes, and inflectional markings. The computational difficultyof the task can be clarified by investigating specific models of morphological processing. The use of finite-state machinery in the "twolevel" model by K i m m o Koskenniemi gives it the appearance of computational efficiency, but closer examination shows the model does not guarantee efficient processing.

• ### Báo cáo khoa học: "DEFINING NATURAL LANGUAGE GRAMMARS IN GPSG"

The computational difficultyof the task can be clarified by investigating specific models of morphological processing. The use of finite-state machinery in the "twolevel" model by K i m m o Koskenniemi gives it the appearance of computational efficiency, but closer examination shows the model does not guarantee efficient processing. Reductions of the satisfiability problem show that finding the proper lexical/surface correspondence in a two-level generation or recognition problem can be computationally difficult.

• ### Báo cáo khoa học: " CONSTRAINT PROPAGATION IN KIMMO SYSTEMS"

Taken abstractly, the two-level (Kimmo) morphological framework allows computationally difficult problems to arise. For example, N + 1 small a u t o m a t a are sufficient to encode the Boolean satisfiability problem (SAT) for formulas in N variables. However, the suspicion arises that natural-language problems may have a special structure - not shared with SAT - - that is not directly captured in the two-level model. In particular, the natural problems may generally have a modular and local nature that distinguishes them from more "global" SAT problems.

• ### Báo cáo khoa học: "Decidability and Undecidability in stand-alone Feature Logics"

This paper investigates the complexity of the satisfiability problem for feature logics strong enough to code entire grammars unaided. We show that feature logics capable of both enforcing re-entrancy and stating linguistic generalisations will have undecidable satisfiability problems even when most Boolean expressivity has been discarded. We exhibit a decidable fragment, but the restrictions imposed to ensure decidability render it unfit for stand-alone use.

• ### STATISTICAL THEORY AND ECONOMETRICS

Econometricians, as well as other scientists, are engaged in learning from their experience and data - a fundamental objective of science. Knowledge so obtained may be desired for its own sake, for example to satisfy our curiosity about aspects of economic behavior and/or for use in solving practical problems, for example to improve economic policymaking. In the process of learning from experience and data, description and generalization both play important roles.

• ### Java Enterprise Best Practices

Ever since Java programmers have downloaded their first virtual machine, their ears have been glued to the ground, constantly on the lookout for tips and tricks for using the latest Java APIs. After all, there's nothing quite as satisfying as grasping a new technique for solving a common programming problem. Remember the first time you learned the power of Model-View-Controller (MVC), or developed your first singleton class? It was clear that someone out there had thought through the same problems you were having and, best of all, developed a solution that worked....
