Panoramic video provides immersive and interactive experience by enabling humans to control the field of view (FoV) through head movement (HM). Thus, HM plays a key role in modeling human attention on panoramic video. This paper establishes a database collecting subjects’ HM positions on panoramic video sequences. From this database, we find that the HM data are highly consistent across subject...

Sixteen Alpine wethers (average BW 35 +/- 2 kg) were used to evaluate the effect of continuous 48-h intravenous infusions of saline (CON), mimosine (MIM; 200 mg.kg.75.d-1), 2-hydroxy-3(1H)-pyridine (2,3-DHP; 200 mg.kg.75.d-1, or MIM+2,3-DHP (100 mg of MIM plus 100 mg of 2,3-DHP-kg.75.d-1) on hepatic function and selected blood metabolite and circulating hormone concentrations. Neither MIM nor 2...

1. BACKGROUND The objective of this chapter is to provide the reader some guidance in applying the Dual Heuristic Programming (DHP) method in the context of designing neural-network controllers. DHP is a member of the class of Critic methods, which in turn is a member of the class of Reinforcement Learning methods. Development of the DHP method benefited from the confluence of several other dev...

Dihydropyridines (DHPs) are L-type calcium channel (Ca(v)1) blockers prescribed to treat several diseases including hypertension. Ca(v)1 channels normally exist in three states: a resting closed state, an open state that is triggered by membrane depolarization, followed by a non-conducting inactivated state that is triggered by the influx of calcium ions, and a rapid change in voltage. DHP bind...

Progesterone is the predominant gestagen in most mammals studied so far. It plays a substantial role regulation of female reproductive cycle and providing support for pregnancy maintenance. Despite its known functions, gaps knowledge are present regarding reduced metabolites that potentially exert biological activity. Therefore, new UHPLC-HRMS method based on Q Exactive™ mass spectrometer was d...

L-type Ca2+ channels are characterized by their unique sensitivity to organic Ca2+ channel modulators like the 1,4-dihydropyridines (DHPs). To identify molecular motifs mediating DHP sensitivity, we transferred this sensitivity from L-type Ca2+ channels to the DHP-insensitive class A brain Ca2+ channel, BI-2. Expression of chimeras revealed minimum sequence stretches conferring DHP sensitivity ...

the 1,4-dihydropyridine (dhp) derivatives are a known class of calcium channel blockers. some derivatives of dhp showed significant cytotoxicity. it was shown that this effect may not be the result of interaction with ca2+ channels. in this study, we performed an investigation about the intrinsic cytotoxicity of some derivatives of dhp containing nitroimidazole moiety on their c4 position on fo...

Amphitrite ornata dehaloperoxidase (DHP) is a heme enzyme with a globin structure, which is capable of oxidizing para-halogenated phenols to the corresponding quinones. Cloning, high-level expression, and purification of recombinant DHP are described. Recombinant DHP was assayed by stopped-flow experiments for its ability to oxidatively debrominate 2,4,6-tribromophenol (TBP). The enzymatic acti...

Acute kidney injury (AKI) occurs in approximately 50% of patients in septic shock, and mortality from septic AKI is extremely high. Angiopoietin levels may play a role in the pathogenesis of vascular permeability. It was reported that direct hemoperfusion with a polymyxin B-immobilized fiber column (DHP-PMX) therapy ameliorates the angiopoietin balance in patients with sepsis. Although dysregul...

Symmetrically substituted octahydroxy porphyrins, tetrakis(3′,5′-dihydroxyphenyl)porphyrin, H2T(3′,5′DHP)P, tetrakis(2′,6′-dihydroxyphenyl)porphyrin, H2T(2′,6′-DHP)P, and their Zn(II) and Mn(III) derivatives have been developed as building blocks for supramolecular hydrogen-bonded networks. The crystal structures of a series of these porphyrins exhibit unique structural features through assembl...
