Predicting the shrinking generator with fixed connections

We propose a novel distinguishing attack on the shrinking generator with known feedback polynomial for the generating LFSR. The attack can e.g. reliably distinguish a shrinking generator with a weight 4 polynomial of degree as large as 10000, using 2(32) output bits. As the feedback polynomial of an arbitrary LFSR is known to have a polynomial multiple of low weight, our distinguisher applies to a

Maturation of the auditory event-related potentials during the first year of life

This study examined the maturation of cortical auditory event-related potentials (ERPs) from birth until 12 months of age. In the 15 infants studied, all ERP peaks observable at 12 months of age, the P150, N250, P350, and N450 were identifiable already at birth, As in previous studies, the amplitudes of the ERP peaks increased and latencies shortened with increasing age. In addition, the time cour

Growth of Verticillium dahliae Kleb. hyphae and of bacteria along the roots of rape (Brassica napus L.) seedlings

Bacterial density and the hyphal density of Verticillium dahliae were determined along the roots of sand-grown rape seedlings. Verticillium dahliae microsclerotia were trapped in nylon nets which were placed in front of the growing root tip. The growing hyphae on the nets were stained with fluorescein diacetate and rhodamine B isothiocyanate. Bacteria on the petri dish lids adjacent to the nets we

14CO2 dispersion around two PWR nuclear power plants in Brazil.

Atmospheric air samples were taken within 3 km from power plants encompassing five different distances and wind directions. Samples were taken between 2002 and 2005 aiming to evaluate the environmental C-14 enrichment due to the operation of Brazilian nuclear power plants. The sampling system consisted of a pump connected to a trapping column filled with a 3 M NaOH solution. The trapped C-14 by us

Photoemission beyond the sudden approximation

The many-body theory of photoemission in solids is reviewed with emphasis on methods based on response theory. The classification of diagrams into loss and no-loss diagrams is discussed and related to Keldysh path-ordering book-keeping. Some new results on energy losses in valence-electron photoemission from free-electron-like metal surfaces are presented. A way to group diagrams is presented in w

Clinical and radiologic evaluation reveals high prevalence of abnormalities in young adults with dysphagia

The purpose of this study was to retrospectively evaluate the radiologic findings in young adults with dysphagia undergoing barium swallow and to compare these with the final clinical diagnosis. Clinical history, barium swallow, endoscopy (21 patients), manometry (18 patients), 24 h pH monitoring (4 patients), and outcome of treatments were studied and compared in 43 patients aged 14-30 years (mea

The structure of Rhodothermus marinus Cel12A, a highly thermostable family 12 endoglucanase, at 1.8 Å resolution

Cellulose is one of the most abundant polysaccharides in nature and microorganisms have developed a comprehensive system for enzymatic breakdown of this ubiquitous carbon source, a subject of much interest in the biotechnology industry. Rhodothermus marinus produces a hyperthermostable cellulase, with a temperature optimum of more than 90 °C, the structure of which is presented here to 1.8 Å resol

Control of ACAT2 Liver Expression by HNF4{alpha}. Lesson From MODY1 Patients.

OBJECTIVE: ACAT2 is thought to be responsible for cholesteryl ester production in chylomicron and VLDL assembly. Recently, we identified HNF1alpha as an important regulator of the human ACAT2 promoter. Thus, we hypothesized that MODY3 (HNF1alpha gene mutations) and possibly MODY1 (HNF4alpha, upstream regulator of HNF1alpha, gene mutations) subjects may have lower VLDL esterified cholesterol. METHO

Activities of Vanadium Oxides in Ammoxidation of 3-Picoline

Ammoxidation of 3-picoline to nicotinonitrile was studied on V2O5, V6O13, and V2O4 catalysts in a fixed-bed integral reactor. The activity studies showed that V6O13 was the most active and selective catalyst of the pure oxides, with a maximum yield of 76% nicotinonitrile at 365 °C. The maximum yield on V2O5 catalyst was 34%, and was obtained at a higher temperature, 458 °C. V2O4 was found to be in

Urethral pressure response patterns induced by squeeze in continent and incontinent women.

Our aim was to compare the urethral pressure response pattern to pelvic floor muscle contractions in 20-27 years old, nulliparous continent women (n=31) to that of continent (n=28) and formerly untreated incontinent (n=59) (53-63 years old) women. These women underwent urethral pressure measurements during rest and repeated pelvic muscle contractions. The response to the contractions was graded 0-

Variable resolution images and their effects on eye-movements during free-viewing

Earlier studies have shown that while free-viewing images people tend to gaze at regions with a high local density of bottom up features such as contrast and edge density. In particular, this tendency seems to be more emphasized during the first few fixations after image onset. In this paper, we present a new method to investigate how gaze locations are chosen by introducing varying image resoluti

Respiration of [C-14] alanine by the ectomycorrhizal fungus Paxillus involutus

The ectomycorrhizal fungus Paxillus involutus efficiently took up exogenously supplied [C-14]alanine and rapidly converted it to pyruvate, citrate, succinate, fumarate and to CO2, thus providing direct evidence for the utilisation of alanine as a respiratory substrate. [C-14]alanine was further actively metabolised to glutamate, glutamine and aspartate. Exposure to aminooxyacetate completely suppr

Characterization of the native CREB3L2 transcription factor and the FUS/CREB3L2 chimera

CREB3L2 was first identified as the 3'-partner of FUS in a fusion gene that seems to be specific for low grade fibromyxoid sarcoma. In silico analyses suggest that the predicted CREB3L2 protein is a member of the CREB3 family of transcription factors, with its bZIP domain being highly similar to that in CREB3L1, CREB3L3, CREB3L4, CREB3, and Drosophila Bbf-2. In the present study, the authors asses
