Dialogue Act Recognition (DAR) is a challenging problem in dialogue interpretation, which aims to attach semantic labels to utterances and characterize the speaker’s intention. Currently, many existing approaches formulate the DAR problem ranging from multi-classification to structured prediction, which suffer from handcrafted feature extensions and attentive contextual structural dependencies....

Currently, traffic congestions are common events in road networks of main cities in developing countries. It has been observed that, the size of congestion increases year after year. For traffic congestion management to work efficiently, sufficiently and accurately information are needed. In this research we present an alternative method using agent technology to collect and manipulate data so ...

Fe(II) complexes containing the fluorinated ligand 1,2-bis(perfluorophenyl)ethane-1,2-dionedioxime (dAr(F)gH(2); H = dissociable proton) exhibit relatively positive Fe(II/I) reduction potentials. The air-stable difluoroborated species [(dAr(F)gBF(2))(2)Fe(py)(2)] (2) electrocatalyzes H(2) generation at -0.9 V vs SCE with i(cat)/i(p) ≈ 4, corresponding to a turnover frequency (TOF) of ∼20 s(-1) ...

PRIMARY OBJECTIVE This prospective controlled non-randomized study investigated the effects of robotic gait training on electroencephalographic (EEG) brain activity in patients with impaired consciousness due to severe traumatic brain injury (TBI). METHODS Twelve TBI patients and 14 healthy controls underwent a single training session on a computer-driven gait orthosis (Lokomat®). The sensory...

BACKGROUND An epidemic of bilateral optic neuropathy is affecting large numbers of people aged between 10 and 40 in Dar es Salaam, the capital city of Tanzania. The disease is characterised by acute onset of bilateral visual impairment, bilateral impairment of colour vision, and a characteristic temporal pallor of the optic discs. The disease often occurs in association with peripheral neuropat...

OBJECTIVE To describe how demographic characteristics and knowledge of cervical cancer influence screening acceptance among women living in Dar es Salaam, Tanzania. METHODS Multistage cluster sampling was carried out in 45 randomly selected streets in Dar es Salaam. Women between the ages of 25-59 who lived in the sampled streets were invited to a cervical cancer screening; 804 women accepted...

OBJECTIVES This study was performed to examine the potential contributions of sociocultural activities to reduce risks of death by homicide. METHODS This study was designed as a case control study. Relatives of 90 adult homicide victims in Dar es Salaam Region, Tanzania, in 2005 were interviewed. As controls, 211 participants matched for sex and 5-year age group were randomly selected from th...

OBJECTIVE To assess the dietary determinants of serum total cholesterol. DESIGN Cross-sectional population-based study. SETTING Peri-urban region of Dar es Salaam, Tanzania. PARTICIPANTS 347 adults aged 40 years and older from the Dar es Salaam Urban Cohort Hypertension Study. MAIN OUTCOME MEASURE Serum total cholesterol measured using a point-of-care device. RESULTS Mean serum total ...

Weedy rice has much stronger seed dormancy than cultivated rice. A wild-like weedy strain SS18-2 was selected to investigate the genetic architecture underlying seed dormancy, a critical adaptive trait in plants. A framework genetic map covering the rice genome was constructed on the basis of 156 BC(1) [EM93-1 (nondormant breeding line)//EM93-1/SS18-2] individuals. The mapping population was re...

Nucleotide excision repair (NER), which is arguably the most versatile DNA repair system, is strongly attenuated in human cells of the monocytic lineage when they differentiate into macrophages. Within active genes, however, both DNA strands continue to be proficiently repaired. The proficient repair of the nontranscribed strand cannot be explained by the dedicated subpathway of transcription-c...
