One of the most fascinating topics in biology is to understand the development of highly differentiated cells such as photoreceptors (PRs). This process involves successive steps, starting with the generation of the eye primordium, recruitment and specification of PRs and finally, expression of the proper rhodopsin, the photopigment that initiates the signaling cascade underlying light input ex...

In this paper, we elaborate on our earlier work on modelling the mental states of PRS-like agents by considering the logical properties of intentions and various rationality postulates for PRS-like agents that are a consequence of this modelling, in particular Bratman’s asymmetry thesis, the side effect problem for intentions and Rao and Georgeff’s nontransference principles. We show that PRS-l...

Fetal ultrasonography is an important tool used to prenatally diagnose many craniofacial conditions. Pierre Robin sequence (PRS) is a rare congenital deformation characterized by micrognathia, glossoptosis, and airway obstruction. PRS can present as a perinatal emergency when the retropositioned tongue obstructs the airway leading to respiratory compromise. More predictable and reliable diagnos...

OBJECTIVE To assess the concentration of progesterone (PRs) and oestrogen (ORs) receptors of myometrium of full-term pregnant women in the myometrium of lower segment of the uterus in relationship with presence or absence of labour. METHODS This was a cross-sectional prospective study with 21 pregnant women, being 6 in labour (Group I) and 15 without labour (Group II). The biopsy of myometriu...

The Scenario-based Engineering Process (SEP) is a novel approach to developing complex systems (Haddock 8z Harbison 1994). SEP builds new application systems through a selection process that groups primitive components into application specific components. The selection of primitive components and the construction of interfaces among components in an application system is currently a tedious ma...

INTRODUCTION This in vivo study assessed whether there was a difference between periapical radiographs (PRs) and cone-beam computed tomographic (CBCT) imaging in the detection, assessment, and management of external cervical resorption (ECR). The secondary aim was to determine if parallax radiographs were of any further benefit compared with a single PR. METHODS PR and CBCT data were gathered...

P. polyphylla Smith var. chinensis (Franch.) Hara (PPSCFH) has been used as medicinal Paris for the prevention and treatment of cancers in China for thousands of years. Its main components, steroidal saponins (PRS), have been confirmed to inhibit tumor growth. In the present study, the immunostimulation of PRS was investigated in Lewis bearing-C57BL/6 mice while the induction of apoptosis in A5...

BACKGROUND This study aimed to investigate prolactin related symptoms (PRS) in individuals with schizophrenia during risperidone maintenance treatment for one year, as well as to identify the risk factors for PRS. METHODS In a multicenter, randomized, controlled, longitudinal study, clinically stabilized schizophrenia patients (N = 374) were randomized to a no-dose-reduction group (N = 129) a...

In this paper, we extend our work in [4] which employed Partial Reed-Solomon (PRS) Codes at coding rates near channel capacity on a Binary Erasure Channel (BEC). We demonstrated that an appropriately designed PRS code outperforms the classical Reed-Solomon (RS) code for a performance criterion tailored for realtime applications. This paper extends this analysis for a general BEC with varying ch...
