We present a thorough study of the theoretical properties and devise efficient algorithms for persistent Laplacian, an extension standard combinatorial Laplacian to setting pairs (or, in more generality, sequences) simplicial complexes $K \hookrightarrow L$, which was recently introduced by Wang, Nguyen, Wei. In particular, analogy with nonpersistent case, we first prove that nullity $q$th $\De...

Although substantial knowledge has been accumulated on cerebellar granule cell voltage-dependent currents, their role in regulating electroresponsiveness has remained speculative. In this paper, we have used patch-clamp recording techniques in acute slice preparations to investigate the ionic basis of electroresponsiveness of rat cerebellar granule cells at a mature developmental stage. The gra...

Insulin from islet β-cells maintains glucose homeostasis by stimulating peripheral tissues to remove glucose from circulation. Persistent elevation of insulin demand increases β-cell number through self-replication or differentiation (neogenesis) as part of a compensatory response. However, it is not well understood how a persistent increase in insulin demand is detected. We have previously dem...

This study addresses the underlying spatial distribution of oak mistletoe, Phoradendron villosum, a hemi-parasitic plant that provides a continuous supply of berries for frugivorous birds overwintering the oak savanna habitat of California's outer coast range. As the winter community of birds consuming oak mistletoe varies from group-living territorial species to birds that roam in flocks, we a...

The pre-Bötzinger complex is a small region in the mammalian brainstem involved in generation of the respiratory rhythm. As shown in vitro, this region, under certain conditions, can generate endogenous rhythmic bursting activity. Our investigation focused on the conditions that may induce this bursting behaviour. A computational model of a population of pacemaker neurons in the pre-Bötzinger c...

Electron bands in the untwisted bilayer graphene flatten out a transverse electric field, offering promising platform for correlated electron physics. We predict that spin/valley isospin magnetism, resembling seen moir\'{e} bands, coexists with momentum-polarized phases occurring via ``flocking transition'' momentum space. This transition results distribution being spontaneously displaced relat...

Human chromosomal DNA contains many repeats which might provide opportunities for DNA repair. We have examined the consequences of a single double-strand break (DSB) within a 360-kb dispensable yeast artificial chromosome (YAC) containing human DNA (YAC12). An Alu-URA3-YZ sequence was targeted to several Alu sites within the YAC in strains of the yeast Saccharomyces cerevisiae; the strains cont...

T r q a r n t e p d h h i o t e s Most virologists would accept the concept that particular viruses often appear to have either acute or persistent patterns of host infection. The polyomaviruses of mammals, for example, uniformly establish persistent infections of a specific host. In contrast, it has recently become clear that avian polyomaviruses infect a broad array of bird species in an acut...

Background: Few cases of persistent hyperinsulinemic hypoglycemia of infancy (PHHI) have been reported, so far. The main concern in the management of PHHI is to prevent severe hypoglycemia, which can lead to coma, brain damage and mental retardation. Total or subtotal pancreatectomy is normally required for the infants, despite the availability of medical therapies. Case report: In this report...
