Drill string axial vibration and sonic head analysis

open access: yes, 2012
This study contains several analyses about vibration generation devices and axial vibration in the drill string. Advanced Drilling Group (ADG) has been seeking new technologies in drilling to improve the rate of penetration (ROP), and in this regard ...

Information and affective valence influence judgments of complexity, liking and understanding

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Visual complexity is a key factor in perceptual and evaluative judgments. People's representation of visual complexity is constructed from quantitative and structural image features, but it is also influenced by familiarity and expertise. We examined how people represent visual complexity and its impact on perception and evaluation, focusing ...

The effectiveness of implementation intentions in children: A systematic review and meta‐analysis

open access: yesBritish Journal of Psychology, EarlyView.
Abstract Self‐regulation abilities in childhood are important for long‐term academic achievement and healthy development. As self‐regulatory abilities are still developing, ‘simple’ interventions are needed to foster self‐regulation. Implementation intentions are simple plans that could promote goal achievement in children.

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

ReTrace: Interactive Visualizations for Reasoning Traces of Large Reasoning Models

open access: yesComputer Graphics Forum, EarlyView.
Abstract Recent advances in Large Language Models have led to Large Reasoning Models, which produce step‐by‐step reasoning traces. Such traces may offer insight into how models think, improving explainability and clarifying the underlying process. These traces, however, are often verbose and complex, making them cognitively demanding to comprehend ...

Effect of Bit Type on Reactive Torque and Consequent Tool-face-control Anomalies

open access: yesShiyou jixie, 2017
In sliding drilling with bend house mud motor, given the same WOB, the reactive torque is greater and the directional drilling is more difficult if the drill bit is more aggressive.

Effects of restoration practices on biodiversity in temperate and boreal forests

open access: yesConservation Biology, EarlyView.
Abstract Several restoration practices are used to mitigate and compensate for the negative effects of large‐scale forestry on biodiversity in temperate and boreal forests. A comprehensive synthesis of the benefits of these practices across taxa is missing. We conducted a systematic review and meta‐analysis on this topic.

Unexpected Promotion of Bone Regeneration by Inhibition of BMPR1A‐Mediated BMP Signalling

open access: yesCell Proliferation, EarlyView.
BMPR1A downregulation reduces ID1, releases TCF3 to activate GNG4‐PI3K‐AKT signalling, thereby promoting OPC proliferation and bone regeneration. ABSTRACT Bone morphogenetic protein (BMP) signalling plays a pivotal role in bone regeneration by regulating osteoprogenitor cell (OPC) function, and BMPs have been widely used in clinical treatment. However,

The Effect of Tensile Stress on Longitudinal Wave Characteristics of Drill String for Gas Drilling

open access: yesShiyou jixie, 2020
To analyze the influence of tensile stress of drill string on the propagation characteristics of longitudinal waves during gas drilling, and to improve the quality and distance of acoustic signal transmission, a stress-longitudinal wave velocity analysis

Collagen Type VI Alpha 1 as a Regulator of Redox Homeostasis in Antioxidant‐Enhanced Osteogenesis of Dental Stem Cells

open access: yesCell Proliferation, EarlyView.
Under physiological conditions, NAC activates the PI3K‐AKT‐COL6A1 axis to sustain redox balance and enhance osteogenesis. COL6A1 deficiency, however, compromises this axis, inducing oxidative stress and impairing NAC's osteogenic efficacy. ABSTRACT Alveolar bone injury represents a prevalent clinical challenge in dentistry, for which stem cell‐based ...
