Cell-replacement therapies have long been an attractive prospect for treating Parkinson disease. However, the outcomes of fetal tissue-derived cell transplants in individuals with Parkinson disease have been variable, in part owing to the limitations of fetal tissue as a cell source, relating to its availability and the lack of possibility for standardization and to variation in methods. Advances

The article presents the main results of a joint investigation by Swedish researchers and industry representatives carried out during 2006-2007 concerning the benefits of modern object based information and communication technology, ICT, for industrialisation of the building industry. The background for the investigation was an experience by both parties of a lack of coherence between scientific r

This paper presents recursive formulas which admit simultaneous tests of stability and evaluation of quadratic loss functions for linear discrete-time dynamical systems. The method admits a significant reduction of the number of computations in comparison with previously known methods.

This study identifies teachers’ perceptions of requirements for including collaborations with the surrounding world in their teaching practice, with the aim of providing authentic and entrepreneurial learning environments for students. School management, time and teachers’ personal character traits and disposition were the most frequently stated areas of concern, followed by colleagues, surroundin

In this paper, physical bounds on scattering of acoustic waves over a frequency interval are discussed based on the holomorphic properties of the scattering amplitude in the forward direction. The result is given by a dispersion relation for the extinction cross section which yields an upper bound on the product of the extinction cross section and the associated bandwidth of any frequency interval

This environmental audit report was completed after an environmental audit of the Baltijsk municipality in the District of Kaliningrad, Russia, during the 10th and 11th of April 2000. The report is a joint effort of 31 students from 23 countries, who are participants of the International Master’s Programme “Master of Science in Environmental Management and Policy ” at the International Institute

Pancreatic ductal adenocarcinoma has one of the worst survival rates among adult cancers, with only 11% in the United States surviving five years after diagnosis. The majority of patients are diagnosed with late-stage disease, since early-stage pancreatic ductal adenocarcinoma is typically either asymptomatic or presents with non-specific symptoms. Pancreatic ductal adenocarcinoma thus remains a h

In this concluding chapter, we draw together the threads of the different assessments carried out by the contributors and propose directions for future research. After a brief overview of the content of the chapters, we revisit and complicate the initial taxonomy we offered, attempting to suggest instead a more abstract classification that could serve as a basis for future assessments. Moreover, w

We develop an advanced mean held method for approximating averages in probabilistic data models that is based on the Thouless-Anderson-Palmer (TAP) approach of disorder physics. In contrast to conventional TAP. where the knowledge of the distribution of couplings between the random variables is required. our method adapts to the concrete couplings. We demonstrate the validity of our approach, whic

This article attempts to prove that an adequate cognition oriented approach to the processing of symbolic information abstracted from verbal expressions must consider a running text instead of scattered sentences. It is argued that the dominant cognition models do not give due consideration to the fact that a valid abstraction of in-formation structures has to be based on an explicit encoding of i

Inhibition of dipeptidyl peptidase-4 (DPP-4) prevents the inactivation of glucagon-like peptide-1 (GLP-1). This increases circulating levels of active GLP-1, stimulates insulin secretion and inhibits glucagon secretion, resulting in lowering of glucose levels and improvement of glycemic control in patients with type 2 diabetes. Several DPP-4 inhibitors are emerging for therapeutic use. Most experi

The one-dimensional inverse scattering problem is considered for potentials that grow without limit for large values of x. The Marchenko method is established for this class of potentials, and several properties of the solution to the Schrödinger equation are developed. In the derivation of the Marchenko equation an extension of the triangularity condition is used. Some brief remarks on the relati

Neural firing rates are thought to represent values which code information. There are drawbacks with using biophysical events to represent numbers. (1) Rate code (like any sequence) is inherently slow to read. (2) At short intervals, the code becomes unintelligible biophysical noise. (3) Transmission times. The vital contribution of the cerebellum to skilled execution and coordination of movements

The Restricted Syndrome Decoding Problem (RSDP) is a variant of the well-known syndrome decoding problem. It has been recently turned into a post-quantum signature scheme named CROSS by Baldi et al.. It is a scheme highlighted for being computationally friendly and providing a compact signature and public key size. This paper investigates an Oracle-based definition of the RSDP that has already pro
