Geometric Evolvement, Simulation, and Test of a Bionic Lateral PDC Reamer Bit Inspired by Capra sibirica Horn

Applied Bionics and Biomechanics, 2022
PDC (polycrystalline diamond compact) bit is the key equipment for drilling holes inside the rock in oil and mining industry. Inspired by the shape and structure of Capra sibirica horn, a bionic lateral PDC reamer bit with variable lateral reaming radius

Miniaturized Conductometric Biosensor for Rapid Detection of TNF‐α in Saliva

Advanced NanoBiomed Research, EarlyView.
A miniaturized conductometric sensor detects TNF‐α at femtomolar levels with high selectivity. The device enables noninvasive testing using pooled human saliva and supports smartphone‐based, real‐time resistance readings. This portable biosensor offers a practical alternative for monitoring TNF‐α, providing new opportunities for diabetes and related ...

Analysis of Torsional Vibration Characteristics of PDC Bit and Design of the Damping Tool

Shiyou jixie, 2017
In order to suppress the torsional vibration of the PDC bit, the torsion model of PDC bit was established.The force on the PDC cutter during rock breaking was analyzed to attain the relationship between WOB and torque.

One-step deterministic polarization entanglement purification using spatial entanglement

, 2010
We present a one-step deterministic entanglement purification protocol with linear optics and postselection. Compared with the Simon-Pan protocol (Phys. Rev. Lett. 89, 257901 (2002)), this one-step protocol has some advantages.

DRILLING BIT PDC PLATES LIFETIME CONTROL

Известия Томского политехнического университета: Инжиниринг георесурсов, 2021
The relevance of the research is caused by the fact that nowadays it will be impossible to explore the georesources if we don’t provide the drilling operations. A great part of the drilling operation is provided with the aid of PDC-bits that beyond that are used for drilling for oil and gas follow-up production.

A study on PDC drill bits quality [PDF]

Wear, 2013
The quality of innovating PDC (Polycrystalline Diamond Compact) bits materials needs to be determined with accuracy by measuring cutting efficiency and wear rate, both related to the overall mechanical properties. An original approach is developed to encompass cutting efficiency and wear contribution to the overall sample quality.

Resource Allocation for Delay Differentiated Traffic in Multiuser OFDM Systems [PDF]

, 2006
Most existing work on adaptive allocation of subcarriers and power in multiuser orthogonal frequency division multiplexing (OFDM) systems has focused on homogeneous traffic consisting solely of either delay-constrained data (guaranteed service) or non ...

Multi‐omic profiling reveals immune cell priming signature linked to lupus prognosis

Arthritis &Rheumatology, Accepted Article.
Objective Systemic lupus erythematosus (SLE) is a multi‐organ disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.

Efficient scheme for three-photon Greenberger-Horne-Zeilinger state generation

, 2012
We propose an efficient scheme for the generation of three-photon Greenberger-Horne-Zeilinger (GHZ) state with linear optics and postselection. Several devices are designed and a two-mode quantum nondemolition (QND) detection is introduced to obtain the ...
