One component of every multi-stage stochastic program is a ltration that determines the notion of which random events are observable at each stage of the evolution. Within the context of interior-point methods, we describe an e cient pre-ordering technique, called ltered dissection, that takes advantage of the ltration's structure to dramatically reduce ll-in in the factorization as compared wi...

The application of microfabrication technology to create precise separation and isolation membranes for biomedical applications is described. By utilizing fabrication techniques commonly employed in the microelectronics industry (MEMS), membranes can be fabricated with well-controlled and uniform pore sizes, allowing the optimization of membrane parameters for biomedical applications in cell im...

Given two{dimensional images T1::n; 1::n] and P1::m; 1::m] where m < n, we develop a fast rotation invariant ltration algorithm for nding the locations of approximate occurrences of P in T. In such an occurrence, each pixel of T should match the corresponding intervals of pixels deened by P. Our lter works by extracting linear sequences of intervals , called features, from P, and by searching t...

Most commonly used similarity search methods in genomic sequences are heuristic ones.These are based upon text ltering that allows one to infer potential regions of similarity. Thisthesis proposes new lter de nitions to search for similarities in genomic sequences, and fastalgorithms to measure the e ciency of these lters.More precisely, we study the spaced seed model and propos...

Severe lung strongylosis was detected in a wild red fox (Vulpes vulpes) (1/12) from Apulia (Italy). We performed routine diagnostics on 12 foxes found dead in Apulia. Eleven of them showed lesions consistent with a vehicle collision. However, the remaining fox appeared to have died from other causes. At necropsy we observed, catarrhal enteritis, fatty liver, lung congestion with some areas rm i...

A chymotryps in l ike endopeptidase has been purif ied by ion-exchange chromatography, affinity chromatography, and gel f i l tration. The enzyme preparation is homogeneous in the u l t r a centrifuge and disc electrophoresis. The enzyme is proved to be free f rom any other proteolytic activities. The molecular weight of the proteinase as determined w i t h several techniques (ultracentrifugati...

We consider the problem of nding the occurrences of two{ dimensional pattern P1::m;1::m] in two{dimensional text T1::n; 1::n] when also rotations of P are allowed. A fast ltration{type algorithm is developed that nds in T the locations where a rotated P can occur. The corresponding rotations are also found. The algorithm rst reads from P a linear string of length m in all O(m 2) orientations th...

We consider Markov process fX(t); t 0g with the extended generator A and the domain D(A). Let fF t g be the right-continuous history ltration and by I P t we denote the restriction of IP to fF t g. Let ~ I P be another probability measure on ((; F) such that d ~ I P t =dI P t = M (t), where M (t) = h(X (t)) h(X (0)) exp ? Z t 0 (Ah)(X(s)) h(X (s)) ds ; is a true martingale for a positive functi...

A 61-year-old male presented with a fungating ulcer over his left inferior peri-orbital region. The tumour fi rst started 10 years ago as a small lesion on his lower eyelid and over the last 2 years, it had grown rapidly, causing a loss of vision of the left eye. He otherwise was systemically well. Clinical examination revealed a large ulcer with irregular, raised borders and impetiginisation (...

Consistent with the understanding of comorbidity-infl ammation relationship, concomitant diseases and especially metabolic comorbidities are thought to stimulate development severity heart failure preserved ejection fraction through a cascade mechanisms supporting systemic tissue infl leading myocardial fi brosis. Recently, new experimental clinical evidence has emerged that enhances validity veri...
