Average Frobenius distribution for inerts in
No full textThe authors of the paper under review extend their study of the Lang-Trotter conjecture for elliptic curves [Internat. Math. Res. Notices 1999, no. 4, 165--183; MR1677267 (2000g:11045)] to the generalised Lang-Trotter conjecture for elliptic curves, as formulated on page 182 of the paper under review. More precisely, they study the function
1#C∑E∈Cπr,fE(x),
where C is a suitable set of elliptic curves E which may depend on x, #C is the cardinality of the set C, and
πr,fE(x)=#{p:N(p)≤x,degK(p)=f, and ap(E)=r},
where E is an elliptic curve over a number field K/Q with a minimal model over the ring of integers OK, r is any fixed integer, f is a divisor of the degree [K:Q] of K over Q, p is a prime ideal in the ring of integers OK, N(p)=pf is the number of elements of the finite field OK/p, the degree of p over K is degK(p)=f, and the trace of Frobenius ap(E)=#Ep(OK/p)−N(p)−1 satisfies the Hasse bound |ap(E)|≤2N(p)−−−−√=2pf/2.
The main result of the paper under review is that for any given nonzero integer r,
1#Cx∑E∈Cxπr,2E(x)∼crloglogx,
where K=Q(i), Cx is the set of elliptic curves E:Y2=X3+αX+β, with α=a1+a2i∈Z[i], β=b1+b2i∈Z[i], and max{|a1|,|a2|,|b1|,|b2|}≤xlogx, and
cr=13π∏l>2l(l−1−(−r2l))(l−1)(l−(−1l))=1.07820...3π.
Furthermore, if r=0, then
1#Cx∑E∈Cxπ0,2E(x)<∞.
This result is in agreement with the generalised Lang-Trotter conjecture in the case f=2, which asserts that there exists a positive constant CE,r,f such that
πr,2E(x)∼CE,r,2loglogx.
The main ingredients in the proof of the main result are rapidly decreasing functions and contour integration as found in the work by A. Akbary, David and the reviewer [Acta Arith. 111 (2004), no. 3, 239--268; MR2039225 (2004k:11086)], coupled with the framework outlined by the authors of the paper under review in [op. cit.]. The authors remark that a similar result should hold for inerts in a general imaginary quadratic field, but that it is not clear how to generalise the technical details of their proof to this general case

Cult: A Composite Novel
No full textCult (redacted)
The first component of the thesis is a composite novel called Cult which falls into two parts with seven narratives in each. Part 1 tracks the protagonist, Ellen, from her first involvement with the cult through to her eventually leaving it. Although fiction, the first half of the book answers the kinds of questions the author is asked when people discover that she was once a sannyasin (a follower of the guru Bhagwan Shree Rajneesh). While the experiences of meditation, group therapy and communal living are all faithfully rendered within the stories, the need for strong characters, narrative drive and a lightness of touch takes precedence.
Part 2 picks up Ellen’s story some twenty or so years later and explores what becomes of her in middle age. It also looks at other groups in society, such as academia, the law and the internet dating community which each have their own jargon, hierarchies, rituals and rules but are not considered to be cults.
The book examines the question raised in the Epigraph, ‘how do we be together when we feel so alone’ with a focus on relationships other than the familial and the romantic.
Collisions, Chasms and Connections: a Performative Exploration of the Composite Novel Form
The second part of the thesis is both a critical and creative response to three contemporary American books: Olive Kitteridge by Elizabeth Strout; A Visit from the Goon Squad by Jennifer Egan; and Legend of a Suicide by David Vann. The critical element comprises a close reading of the three books; a chronological reconstruction of their overarching storylines; and a consideration of what their authors have said about writing the books. It concludes that, in the composite novel, the simultaneous presentation of multiple views and storylines operate much like a 3D image to give the impression of depth to the characters and situations rendered. The creative element of the essay is a playful and personal response to the texts
Analysis of a File System Using the Verifying C Compiler
No full textTitle: Analysis of a File System Using the Verifying C Compiler Author: Bc. David Škorvaga Department: Department of Distributed and Dependable Systems Supervisor: RNDr. Jan Kofroň, Ph.D. Abstract: Formal verification is a way to improve reliability of software systems. One approach of formal verification is focused on proving correctness of annotat- ed source code of an established programming language. Verifying C Compiler (VCC) is a verifier for concurrent C that accepts an annotated code in C language and automatically verifies its correctness with respect to the given annotation. There have been successful attempts to verify some critical systems, including the operating system kernel. Another critical part of operating system is its file system. In the thesis, we choose FatFs file system, a simple device-independent implementation of the FAT file system. We specify a part of it using the VCC annotation and successfully verify its correctness. Keywords: Formal Verification, File System, VC

Jeden z přístupů formální verifikace se zaměřuje na dokazo- vaní správnosti anotovaného zdrojového kódu v široce používaném programovacím jazyce. Verifier C Compiler (VCC) je verifikátor pro concurrent C, který přijímá anotovaný kód v jazyce C a automaticky ověřuje jeho správnost s ohledem na tuto anotaci. Už se objevily úspěšné pokusy o ověření některých kritických systémů, včetně jádra operačního systému. Další důležitou součástí operačního systému je jeho systém souborů. V diplomové práci jsme si vybrali souborový systém FatFs, odlehčenou implementaci souborového systému FAT, nezávislou na zařízení. V této práci vytvoříme specifikaci jeho části pomocí anotace VCC a úspěšně ověříme jeho korektnost.

Protein Free Energy Landscapes Remodeled by Ligand Binding
No full textAbstractGlucose/galactose binding protein (GGBP) functions in two different larger systems of proteins used by enteric bacteria for molecular recognition and signaling. Here we report on the thermodynamics of conformational equilibrium distributions of GGBP. Three fluorescence components appear at zero glucose concentration and systematically transition to three components at high glucose concentration. Fluorescence anisotropy correlations, fluorescent lifetimes, thermodynamics, computational structure minimization, and literature work were used to assign the three components as open, closed, and twisted conformations of the protein. The existence of three states at all glucose concentrations indicates that the protein continuously fluctuates about its conformational state space via thermally driven state transitions; glucose biases the populations by reorganizing the free energy profile. These results and their implications are discussed in terms of the two types of specific and nonspecific interactions GGBP has with cytoplasmic membrane proteins
