<P>One of the most popular approaches to parameter adaptation in hidden Markov model (HMM) based systems is the maximum likelihood linear regression (MLLR) technique. In this letter, we extend MLLR to factored MLLR (FMLLR) in which the MLLR parameters depend on a continuous-valued control vector. Since it is practically impossible to estimate the MLLR parameters for each control vector separately, we propose a compact parametric form of the MLLR parameters. In the proposed approach, each MLLR parameter is represented as an inner product between a regression vector and transformed control vector. We present an algorithm to train the FMLLR parameters based on a general framework of the expectation-maximization (EM) algorithm. The proposed approach is applied to adapt the HMM parameters obtained from a database of reading-style speech to singing-style voices while treating the pitches and durations extracted from the musical notes as the control vectors. This enables to efficiently construct a singing voice synthesizer with only a small amount of singing data.</P>

<P>Whole cells of the basidiomycete fungus Phanerochaete chrysosporium (ATCC 20696) were applied to induce the biomodification of lignin in an in vivo system. Our results indicated that P. chrysosporium has a catabolic system that induces characteristic biomodifications of synthetic lignin through a series of redox reactions, leading not only to the degradation of lignin but also to its polymerization. The reducing agents ascorbic acid, and alpha-tocopherol were used to stabilize the free radicals generated from the ligninolytic process. The application of P. chrysosporium in combination with reducing agents produced aromatic compounds and succinic acid as well as degraded lignin polymers. P chrysosporium selectively catalyzed the conversion of lignin to succinic acid which has an economic value. A transcriptomic analysis of P. chrysosporium suggested that the, bond cleavage of synthetic lignin was caused by numerous enzymes, including extracellular enzymes such as lignin peroxidase and manganese peroxidase, and that the aromatic compounds released were metabolized in both the short-cut and classical tricarboxylic acid cycles of P. chrysosporium. In conclusion, P. chlysosporium is suitable as a biocatalyst for lignin degradation to produce a value-added product.</P>
Mechanism of Relaxation Via TASK-2 Channels in Uterine Circular Muscle of Mouse

Plasma pH can be altered during pregnancy and at labor. Membrane excitability of smooth muscle including uterine muscle is suppressed by the activation of $K^+$ channels. Because contractility of uterine muscle is regulated by extracellular pH and humoral factors, $K^+$ conductance could be connected to factors regulating uterine contractility during pregnancy. Here, we showed that TASK-2 inhibitors such as quinidine, lidocaine, and extracellular acidosis produced contraction in uterine circular muscle of mouse. Furthermore, contractility was significantly increased in pregnant uterine circular muscle than that of non-pregnant muscle. These patterns were not changed even in the presence of tetraetylammonium (TEA) and 4-aminopyridine (4-AP). Finally, TASK-2 inhibitors induced strong myometrial contraction even in the presence of L-methionine, a known inhibitor of stretch-activated channels in myometrium. When compared to non-pregnant myometrium, pregnant myometrium showed increased immunohistochemical expression of TASK-2. Therefore, TASK-2, seems to play a key role during regulation of myometrial contractility in the pregnancy and provides new insight into preventing preterm delivery.
The Effect of Travel Constraints on Behavioral Intention of Package and Incentive Tourists Focus

Group package-tours comprise the mainstream mode of outbound travel, particularly in Asia; however, authority-paid incentive travel is rapidly gaining momentum. Participation in both travel categories has risen dramatically among Chinese outbound tourists. Our study sought to determine whether there are differences between the two types of travelers in terms of demographic and travel characteristics, and if so, how those differences might impact each travel group"s future travel behavior. Our study population was Chinese tourists visiting Jeju Island. Using data obtained in standard questionnaires, we compared and analyzed the effect of perceived travel constraints on both groups" behavioral intention-a predictor of how likely tourists are to revisit a location or recommend it to others. Results revealed distinct differences between the two groups. Given tourism"s potential economic benefit, it is crucial that tourism professionals know and understand these differences when developing or refining travel programs and marketing strategies.

<P>In the future ubiquitous home network, sensors will collect various home environment data in the home. Since the sensor nodes are equipped with small, often irreplaceable, batteries with limited power capacity, it is essential that the network be energy-efficient in order to maximize its lifetime. Our study, described in this paper, was divided into two classes: the primary class was to set a power-based level and the secondary class was to propose an offer of a home automation using a routing technique centered on a sensor network to set a flooding level. The proposed scheme divides the home into areas such as rooms and locates the WENs in each area. The WENs collect data from sensors and deliver the data to the home base station only. Sensors deliver the data to the WENs or the home base station through the sensor with the stronger power. Performance results show that the proposed scheme is more, efficient with a wireless home network.</P>
