Report on the First VLDB Workshop on Management of Uncertain Data (MUD 2007)
On Monday September 24th, we organized the first international VLDB workshop on Management of Uncertain Data [dKvKD07]. The idea of this workshop arose a year earlier at the Twente Data Management Workshop on Uncertainty in Databases [dKvK06]. The TDM is a bi-annual workshop organized by the Database group of the University of Twente, for which each time a different topic is chosen. The participants of TDM 2006 were enthusiastic about the topic "Uncertainty in Databases" and strongly expressed the wish for a follow-up co-located with an international conference. To fulfill this wish, we organized the MUD-workshop at VLDB
Influence of the autonomic nervous system on the clinical course of overactive bladder
Overactive bladder (OB) is a disease which is very easily diagnosed, but presents considerable difficulties in the choice of treatment mode. At present the specialists turn their attention to this syndrome due to a wide spread of the disease, its negative impact on quality of life, social and economic importance. Pathogenesis of OB is complex. Thus, under conditions of urothelium atrophy which takes place because of estrogen deficiency in postmenopausal women, in violation of its GAG protective layer, barrier function of urothelium are violated, which leads to its damage. The appearence of urination disorder symptoms are
associated with the fact that atrophic mucosa of urethra and triangle of bladder are hypersensitive to even minimal portions of urine. Aging process also play a role
in OB development including lowering ability of tissues to repair, their elasticity reduction, increased apoptosis and cell atrophy, degeneration of nerve endings, smooth muscle tone change, deterioration of urothelium and its GAG protective layer. It can be a result of manifestation of bladder outlet obstruction that causes OB symptoms in men suffering from benign hyperplasia, prostate cancer and chronic prostatitis

Abstract
The authors, in a study on 25 outbred Wistar white rats weighing 180-200 g, determined the effect of Lamidana (a product from sea brown algae) on the structural-functional continuum, that is, the correlation of the functional activity of the liver parenchyma and its structural characteristics. Methods. The detoxifying function of the liver was studied by the duration of sleep of animals due to the action of anesthesia - intraperitoneal administration of sodium thiopental (estimate the rate of metabolism of thiopental, carried out by the cytochrome-P-450-dependent monooxygenase system of hepatocytes). The structural and functional state of the liver parenchyma was assessed according to the study of histological preparations. The results of the studies showed that under the influence of the external application of "Lamidin" in the test rats, the liver1s detoxification function is enhanced (significantly significant decrease in the duration of sleep of animals). At the same time, structural signs of increased functional activity of hepatocytes are determined in the parenchyma. Conclusions. The authors believe that "Lamidan", due to the peculiarities of its chemical composition, enhances the metabolic and functional activity of hepatocytes but does not damage the correlative relationships between the structure and function of hepatocytes.

Justification of the renoprotective action of the mixture of sodium chloride and sodium bicarbonate solutions in phenylhydrazine intoxication
The authors conducted a study on 35 white Wistar outbred rats to investigate the possibility of correcting acute kidney damage induced by the administration of phenylhydrazine at a dose of 100 mg/kg by introducing a mixture of sodium chloride and sodium bicarbonate solutions into the body.
The research results identified changes in the kidneys upon phenylhydrazine administration, including the loss of some capillary glomeruli, eosinophilic deposits in Bowman's spaces and tubular lumens, and lymphoid infiltration in the interstitium. Rats receiving a mixture of sodium chloride and sodium bicarbonate solutions in their drinking water showed positive changes in their kidneys: no loss of capillary glomeruli was observed, and eosinophilic deposits were absent in most tubules. Lymphocyte aggregation was only observed around some renal vessels. The authors suggest that the intake of additional sodium and bicarbonate into the body, along with alkalinization of the primary urine, promotes the excretion of hemolysis products caused by phenylhydrazine, which contributes to renoprotection and preservation of renal parenchyma
Query Algebra Operations for Interval Probabilities
The groundswell for the `00s is imprecise probabilities. Whether the numbers represent the probable location of a GPS device at its next sounding, the inherent uncertainty of an individual expert\u27s probability prediction, or the range of values derived from the fusion of sensor data, probability intervals became an important way of representing uncertainty. However, until recently, there has been no robust support for storage and management of imprecise probabilities. In this paper, we define the semantics of traditional query algebra operations of selection, projection, Cartesian product and join, as well as an operation of conditionalization, specific to probabilistic databases. We provide efficient methods for computing the results of these operations and show how they conform to probability theory
Probabilistic Temporal Databases, II: Calculus and Query Processing
There is a vast class of applications in which we know that
a certain event occurred, but do not know exactly when it
occurred. However, as studied by Dyreson and Snodgrass \cite{ds98}, there
are many natural scenarios where probability distributions exist
and quantify this uncertainty. Dekhtyar et. al. extended Dyreson
and Snodgrass's work and defined an extension of the relational
algebra to handle such data.
The first contribution of this paper
is a declarative temporal probabilistic (TP for short) calculus which we show
is equivalent in expressive power to the
temporal probabilistic algebra of Dekhtyar et. al. Our second major
contribution is a set of equivalence and containment results for the TP-algebra. Our third contribution is the development of
cost models that may be used to estimate the cost of TP-algebra
operations.
Our fourth contribution is an experimental evaluation of the
accuracy of our cost models and the use of the equivalence results
as rewrite rules for optimizing queries by using an implementation
of TP-databases on top of ODBC.

Crystallization of Fe82Si2B16 and Fe82Si4B14 metallic glasses upon isothermal and non-isothermal annealing
Crystallization of Fe82Si2B16 and Fe82Si4B14 metallic glasses upon heat treatment has been studied. The amorphous ribbons have been isothermally annealed at different temperatures (673, 693, 733 and 743 K) and for various times (from 15 min to 78 hours). Phase compositions and the sequence of their appearance in dependence on the annealing temperature and time have been established
