let $k$ be a field of characteristic$p>0$, $k[[x]]$, the ring of formal power series over $ k$,$k((x))$, the quotient field of $ k[[x]]$, and $ k(x)$ the fieldof rational functions over $k$. we shall give somecharacterizations of an algebraic function $fin k((x))$ over $k$.let $l$ be a field of characteristic zero. the power series $finl[[x]]$ is called differentially algebraic, if it satisfies...

antifibrotic therapies should preferentially be targeted to the activated hepatic mesenchymal cells. those cells resemble wound healing myofibroblasts and synthesize an excess of extracellular matrix (ecm) proteins. they derive from quiescent hepatic stellate cells (hsc) and portal/perivascular (myo-) fibroblasts (mf). whereas various agents have been shown to inhibit hsc/mf proliferation and c...

Septic arthritis of the adult hip is uncommon. Twenty patients were admitted to the Robert Jones and Agnes Hunt Orthopaedic Hospital with this diagnosis in the ten-year period 1954-63, out of a total of 27,263 admissions. Because of its rarity the disease is liable to be wrongly diagnosed, or diagnosed at a late stage when the prospects of complete joint recovery are small. Material-This series...

October 10th, 2016 marked the 9th anniversary for the Journal of Biological Engineering (JBE), the official journal of Institute of Biological Engineering (IBE), published by BioMed Central. We are entering into the 10th year of its exciting and productive history. In this editorial, a brief history of JBE is summarized, along with a series of analyses on average number of citations, breakdown ...

We prove a new four parameter q-hypergeometric series identity from which the three parameter identity for the Göllnitz theorem due to Alladi, Andrews, and Gordon follows as a special case by setting one of the parameters equal to 0. The new identity is equivalent to a four parameter partition theorem which extends the deep theorem of Göllnitz and thereby settles a problem raised by Andrews thi...

We report here on a series of tricyanovinylaniline chromophores for use as dopants in poled poly(methyl methacrylate)waveguides for anomalous dispersion phase-matched second harmonic generation. Second harmonic generation measurements as a function of mode index confirmed anomalous dispersion phase-matching efficiencies as large as 245%/Wcm over a propagation length of about 35 μm. The waveguid...

Zika virus (ZIKV) had remained a relatively obscure flavivirus until a recent series of outbreaks accompanied by unexpectedly severe clinical complications brought this virus into the spotlight as causing an infection of global public health concern. In this review, we discuss the history and epidemiology of ZIKV infection, recent outbreaks in Oceania and the emergence of ZIKV in the Western He...

Natural language is the primary vehicle of human communication. It involves a series of interlocked processes at various levels of aggregation. Proof theory and dynamic logic provide two paradigms for dealing with this variety. This paper gives an analysis of some main issues that arise in merging the two viewpoints towards this broader goal. Topics discussed include: proof as discourse, interf...

Those born with congenital cataracts tend to develop retinal detachments, irrespective of whether or not cataract surgery is undertaken (Malbran and Dodds, i964), although the patient may reach middle age before the retina separates (Shapland, I962). The prospects of curing such detachments are generally regarded as poor (McDonald, I957), and since the literature is devoid of any series giving ...

We study the effects of time pressure on risky decisions for pure gain prospects, pure loss prospects, and mixed prospects involving both gains and losses. In an experiment we find that risk aversion for gains is robust under time pressure whereas risk seeking for losses turns into risk aversion under time pressure. For mixed prospects, subjects become more loss averse and more gain seeking und...
