Magnetic Electric Detonator Coding Graded Perforation Firing Technology

Cejing jishu
In bridge plug multi-cluster perforation operations, using high resistance detonator in graded perforation poses a safety risk of accidental detonation. Magneto electric detonator have good resistance to environmental electricity.

Construction of SnO2−Graphene Composite with Half-Supported Cluster Structure as Anode toward Superior Lithium Storage Properties

Scientific Reports, 2017
Inspired by nature, herein we designed a novel construction of SnO2 anodes with an extremely high lithium storage performance. By utilizing small sheets of graphene oxide, the partitioned-pomegranate-like structure was constructed (SnO2@C@half-rGO), in ...

Matrix eQTL: Ultra fast eQTL analysis via large matrix operations [PDF]

, 2011
Expression quantitative trait loci (eQTL) mapping aims to determine genomic regions that regulate gene transcription. Expression QTL is used to study the regulatory structure of normal tissues and to search for genetic factors in complex diseases such as

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

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

Understanding the creep property of heat-resistant Al alloy by analyzing eutectic phase/matrix interface structures

Materials Research Letters, 2023
Interface characteristics are of great importance in mechanical performance for multi-phases heat-resistant Al alloys. Herein, Al3Sc precipitates were created at both Al/Al9FeNi interface and Al matrix inside Al–Fe-Ni eutectic alloy by microalloyed Sc ...

Optimal CUR Matrix Decompositions [PDF]

, 2014
The CUR decomposition of an $m \times n$ matrix $A$ finds an $m \times c$ matrix $C$ with a subset of $c < n$ columns of $A,$ together with an $r \times n$ matrix $R$ with a subset of $r < m$ rows of $A,$ as well as a $c \times r$ low-rank matrix $U ...

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

FEBS 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.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Holomorphic matrix models

, 2003
This is a study of holomorphic matrix models, the matrix models which underlie the conjecture of Dijkgraaf and Vafa. I first give a systematic description of the holomorphic one-matrix model.
