An improved Burgers creep model of coal based on fractional-order
Frontiers in Earth Science, 2023 The instability and destruction of various types of coal pillars left in deep underground mining are frequently attributed to cumulative creep deformation exceeding the permissible limit, with high in situ stress playing a critical role in this ...

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review
Pediatric Blood &Cancer, EarlyView.ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Creep and Large-amplitude Oscillatory Shear Behavior of Whey Protein Isolate/κ-carrageenan Gels
Applied Rheology, 2012 Dynamic oscillatory and creep tests are two common rheological methods used to determine viscoelastic properties. In the food industry, these tests are generally performed in the linear viscoelastic region, providing information on food structure and ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Journal of Materials Research and Technology, 2023 The printed circuit heat exchanger (PCHE) is extensively used in several applications due to exceptional compactness and heat transfer efficiency. However, the dominant failure mode of PCHE is creep fracture in its diffusion welding joints. Therefore, an

FEBS 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

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

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

Materials Transactions, JIM, 1996 Under creep conditions at constant temperature, it is well known that transitions may occur between different flow mechanisms depending upon the level of the applied stress. For example, the transitions between the viscous glide of dislocations and control by dislocation climb are now well established in the creep of solid solution alloys.
