Abstract The Cartesian thesis that some justifications are infallible faces a gradation puzzle. On the one hand, justification tolerates absolutely no possibility for error. other can vary in evidential force: e.g. two persons both be regarding their pains while with stronger pain is nevertheless more justified. However, if type of gradable strength, why it always absolute? This paper explores ...

OBJECTIVE Detecting and grading of diabetic retinopathy (DR) by means of digital retinal images sent via the Internet. RESEARCH DESIGN AND METHODS Four nonstereoscopic digital retinal images (45 degrees field each) of 126 eye fundus images from 70 diabetic patients were obtained with a nonmydriatic camera at two peripheral units. The images were sent via the Internet using a web-based system ...

Mining tailings as a raw material for preparing autoclaved bricks have attracted much attention. The tailings subjected to milling always have the characteristic of fine granularity. However, the proportion of the fine aggregates in autoclaved bricks was very low using the current gradation formula, which impeded the utilization of the tailings. In this work, a novel model of aggregate gradatio...

Previous studies have associated visual working memory (VWM) capacity with the ability to use internal attention. Internal attention’s effect on VWM has been studied mostly using object-based retro-cues, which can direct attention particular objects. In addition, by dimension-based retro-cues recent found that directing a feature dimension in improve recall performance. Although mechanism of fo...

Hospital gradation systems are used to examine the performance of hospitals to promote the efficient use of medical resources (1). Patient-perceived service quality may differ for differing grades of medical institutions under gradation system , which has been rarely reported. The aim of the present study was to explore the relation between the hospital gradation system and patient perceptions ...

We construct soliton solutions for non-abelian loop Toda equations associated with general linear groups. Here we consider the untwisted case only and use the rational dressing method based upon appropriate block-matrix representation suggested by the initial Z-gradation.

Objective Chronic Non-specific low back pain (CNSLBP) is described as pain whose pathoanatomical cause cannot be determined. The current study aimed to evaluate the impact of retro-walking on pain, flexibility, and physical functions in patients with CNSLBP. Methods: A randomized controlled trial was conducted in Physical Therapy department of District Head Quarter hospital Nankana Sahib, Punj...

The fate of the aryl gold(I) carbenes generated by retro-Buchner reaction of ortho-substituted 7-aryl-1,3,5-cycloheptatrienes is dependent on the constitution of the ortho substituent. Indenes and fluorenes are obtained by intramolecular reaction of highly electrophilic gold(I) carbenes with alkenes and arenes. According to density functional theory calculations, the gold-catalyzed retro-Buchne...
