This paper is one argument for a theory of grammatical relations in Chinese in which there are no grammatical relations beyond semantic roles, and no lexical relation-changing rules. As the passive rule is one of the most common relation changing rules cross-linguistically, in this paper I will address the question of whether or not Mandarin Chinese has lexical passives, that is, passives defined as in Relational Grammar (see for example Perlmutter and Postal 1977) and the early Lexical Functional Grammar (LFG) literature (e.g. Bresnan 1982), where a 2-arc (object) is promoted to a 1-arc (subject).
We propose two improvements to the Fiat Shamir authentication and signature scheme. We reduce the communication of the Fiat Shamir authentication scheme to a single round while preserving the e±ciency of the scheme. This also reduces the length of Fiat Shamir signatures. Using secret keys consisting of small integers we reduce the time for signature generation by a factor 3 to 4. We propose a variation of our scheme using class groups that may be secure even if factoring large integers becomes easy.
In der folgenden Darstellung geht es einerseits darum, an Beispielen aufzuzeigen, inwiefern die schweizerdeutschen Mundarten und die deutsche Standardsprache in Lautung, Formenbildung, Satzbau und Wortschatz auseinandergehen können, andererseits aber immer auch um das Aufweisen von Gemeinsamkeiten. Oft werden nämlich bestimmte Erscheinungen des dialektalen Sprachbaus vorschnell als Eigenarten der Mundart verstanden, obwohl dieselben Erscheinungen auch im gesprochenen Hochdeutschen anzutreffen sind. Somit liegen also häufig nicht Unterschiede zwischen Mundart und Standardsprache vor, sondern Unterschiede zwischen gesprochener Sprache und geschriebener Sprache.

We present a RQMD calculation of antiproton yields and their momentum distribution in Ne + NaF collisions at 2 GeV/u. The antiprotons can be produced below threshold due to multi-step excitations for which meson-baryon interactions play a considerable role. In this system the annihilation probability for an initially produced antiproton is predicted to be about 65%.
We report on improved practical algorithms for lattice basis reduction. We propose a practical floating point version of theL3-algorithm of Lenstra, Lenstra, Lovász (1982). We present a variant of theL3-algorithm with "deep insertions" and a practical algorithm for block Korkin—Zolotarev reduction, a concept introduced by Schnorr (1987). Empirical tests show that the strongest of these algorithms solves almost all subset sum problems with up to 66 random weights of arbitrary bit length within at most a few hours on a UNISYS 6000/70 or within a couple of minutes on a SPARC1 + computer.
