Neurophysiological evidence of human hippocampal longitudinal differentiation in associative memory

open access: yesNature Communications
In humans, the hippocampus exhibits evident structural and connectivity differences along the longitudinal axis. Experiments in rodents and more recently in human subjects have stimulated several theories of functional longitudinal specialization.

On Closed Modular Colorings of Trees

open access: yesDiscussiones Mathematicae Graph Theory, 2013
Two vertices u and v in a nontrivial connected graph G are twins if u and v have the same neighbors in V (G) − {u, v}. If u and v are adjacent, they are referred to as true twins; while if u and v are nonadjacent, they are false twins.

Cyclic Super Magic Labelings for Toroidal and Klein-Bottle Fullerenes

open access: yesIEEE Access, 2019
A simple graph G = (V, E) admits a cycle-covering if every edge in E belongs at least to one subgraph of G isomorphic to a given cycle C. The graph G is C-magic if there exists a total labeling f : V ∪ E → {1, 2, 3, ..., |V | + |E|} such ...

Direct fermentation of sweet sorghum juice by Clostridium acetobutylicum and Clostridium tetanomorphum to produce bio-butanol and organic acids [PDF]

open access: yesBiofuel Research Journal, 2015
Single- and co-culture clostridial fermentation was conducted to obtain organic alcohols and acids from sweet sorghum juice as a low cost feedstock. Different inoculum concentrations of single cultures (3, 5, 10 v/v %) as well as different ratios of C ...

Optimal Locating-Total Dominating Sets in Strips of Height 3

open access: yesDiscussiones Mathematicae Graph Theory, 2015
A set C of vertices in a graph G = (V,E) is total dominating in G if all vertices of V are adjacent to a vertex of C. Furthermore, if a total dominating set C in G has the additional property that for any distinct vertices u, v ∈ V \ C the subsets formed

Analysis of the X(4475), X(4500), $$Z_{\bar{c}\bar{s}}(4600)$$ Z c ¯ s ¯ ( 4600 ) , and related tetraquark states with the QCD sum rules

open access: yesAAPPS Bulletin
In this work, we introduce an explicit P-wave to construct the diquarks $$[qc]_{\widehat{V}}$$ [ q c ] V ^ , then construct the local four-quark currents to explore the hidden-charm tetraquark states with the $$J^{PC}=0^{++}$$ J PC = 0 + + , $$1^{+-}$$ 1

Linear frequency tuning in an LC-resonant system using a C–V response controllable MEMS varactor

open access: yesMicro and Nano Systems Letters, 2017
This paper proposes a device level solution to achieve linear frequency tuning with respect to a tuning voltage (V tune ) sweep in an inductor (L)–capacitor (C) resonant system. Since the linearity of the resonant frequency vs.

List graphs and distance-consistent node labelings

open access: yesElectronic Journal of Graph Theory and Applications, 2018
In this paper we consider node labelings c of an undirected connected graph G = (V, E) with labels {1, 2, ..., ∣V∣}, which induce a list distance c(u, v) = ∣c(v) − c(u)∣ besides the usual graph distance d(u, v).
