Leadership in the world of the Bible: (De)institutionalisation as an ongoing process

open access: yesVerbum et Ecclesia, 2002
This article discusses the development of leadership in the biblical world in light of structuration theory. The use of the structuration theory is embedded in the theoretical work of Max Weber.

Restructuring Structuration Theory

open access: yes, 1989
The article looks critically at Giddens's duality of structure notion which is at the centre of his structuration theory. It argues that the concept of subject/object dualism, which is not seriously considered by structuration theory, is as essential as

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

On the theory of graded structures

open access: yesJournal of Symbolic Computation, 1986
A new structural algebraic framework is given to the concept and the construction of the generalized standard bases. Graded structure over a commutative ring \(A\), \(v\)-filtered structure on \(A\), modules over a graded structure, modules on the \(v\)-filtered structures and the corresponding morphisms as well as their relationship are considered ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

A Theory of Structure of Slivers

open access: yesJournal of the Textile Machinary Society, 1958
研究目的スライバの太さむらと繊維先端配置との関係を実験的に研究する.またスライバ長さ方向に対する繊維長分布の変化について検討する.研究結果前報で理論的に得られた主な結論が実証された.すなわち(1) 繊維先端配置の変動は, 太さの変動よりはるかに大きい.(2) 繊維先端密度に波長λ, 相対振巾α の正弦波 (調和波) が存在するとき, 太さむらにはこれより位相φ (λ) (≒l/2) だけ遅れた波長λ, 相対振巾αγ (λ, l, σ) の正弦波が生じる.(3) 断面繊維数間相対分散はC2 (S (x)) =k/S-0.6C (l) (k-1) /S+ (1/2) Σ (aγγγ) 2で計算される.(4) ランダムスライバにおいてはC2 (S (x)) =1/S(5 ...

Structured theories in LCF [PDF]

open access: yes, 1983
An extension to the Edinburgh LCF interactive theorem-proving system is described which provides new ways of constructing theories, drawing upon ideas from the Clear specification language. A new theory can be built from an existing theory in two new ways: by renaming its types and constants, or by abstraction (forgetting some types and constants and ...

Theory of aging in structural glasses [PDF]

open access: yesThe Journal of Chemical Physics, 2004
The random first-order transition theory of the dynamics of supercooled liquids is extended to treat aging phenomena in nonequilibrium structural glasses. A reformulation of the idea of “entropic droplets” in terms of libraries of local energy landscapes is introduced which treats in a uniform way the supercooled liquid (reproducing earlier results ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
