A characterization of Janko’s simple group [PDF]

open access: yesProceedings of the American Mathematical Society, 1968
If G is a finite group, we say that a series of subgroups G = Go > G > * > Gn= 1 is a maximal series of length n of G if Gi is a maximal subgroup of Gi1, 1 _ i < n. A subgroup H of G is called mth maximal in G if there exists at least one maximal series H= Gm< Gm.,-<

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Recognition of the simple unitary group PSU 3(p) by its order and degree prime-power graph

open access: yesOpen Mathematics
Let G be a finite group, and let cd (G) denote the set of all irreducible character degrees of G. The set ρ(G) represents all prime divisors of the integers in cd (G). For a prime p and a positive integer n, let n p denote the p part of n.

Quasirecognition by prime graph of finite simple groups ${}^2D_n(3)$ [PDF]

open access: yesInternational Journal of Group Theory, 2014
Let $G$ be a finite group. In [Ghasemabadi et al., characterizations of the simple group ${}^2D_n(3)$ by prime graph and spectrum, Monatsh Math., 2011] it is proved that if $n$ is odd, then ${}^2D _n(3)$ is recognizable by prime graph and also by ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

open access: yesFEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

PEMANFAATAN METODE SAW PENDUKUNG KEPUTUSAN PENILAIAN EFEKTIVITAS MODEL PEMBELAJARAN

open access: yesJurnal Pendidikan: Teori, Penelitian, dan Pengembangan, 2017
Students who are in junior high school should have been able to read children stories appreciative. However, based on the results of research that has been done, appreciative children's story reading skills in students is still low due to the model ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

The exact spread of M23 is 8064 [PDF]

open access: yesInternational Journal of Group Theory, 2012
Let $G$ be a finite group. We say that $G$ has emph{spread} r if for any set of distinct non-trivial elements of $G$ $X:={x_1,ldots, x_r}subset G^{#}$ there exists an element $yin G$ with the property that $langle x_i,yrangle=G$ for every $1leq ileq r ...
