Degree of hydration-based creep modeling of concrete with blended binders : from concept to real applications [PDF]
, 2014 The mechanical behavior of hardening concrete is to a large extent determined by the evolving microstructure as a result of the hydration process. For traditional binder systems, consisting of Portland cement or blast furnace slag cement, the degree of ...

FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

A new creep model directly using tabulated test data and implemented in ansys [PDF]
, 2017 Nowadays plastics are increasingly used in highly stressed structures in all kinds of constructions. The time dependency, the so-called viscosity, is a crucial part of the material behavior of plastics. A typical form of viscosity is creep.

Creep Rupture Behavior of Polyacetal
KOBUNSHI RONBUNSHU, 2004 ポリアセタールの引張クリープ破壊特性を80℃で測定し, ホモポリマーとコポリマーを比較しそのメカニズムを考察した. クリープ破壊機構はクリープ荷重と破壊寿命の相関よりZhurkovの式を用いて活性化体積 (υc) を算出し, 以下のことが明らかになった. (1) ポリアセタールのυcは分子量とともに大きくなる. (2) ホモポリマーに比してコポリマーのυcは大きくコボリマーの方が破壊寿命の荷重依存性が大きいことに対応する. また, 破断面の電子顕微鏡観察からクリープの破壊起点は延性挙動であった. そのため, υcの値を引張変形挙動における引張速度と降伏強度の関係からEyringの式を使って算出した活性化体積 (υy) と比較した. 各材料のυcとυyは同じオーダーの値を示し, ほぼ, υc=1.6υ

Avalanche Behavior in Creep Failure of Disordered Materials [PDF]
Physical Review Letters, 2018 We present a mesoscale elastoplastic model of creep in disordered materials which considers temperature-dependent stochastic activation of localized deformation events which are mutually coupled by internal stresses, leading to collective avalanche dynamics.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...
