Globally, the incidence of cervical cancer ranks fourth among female malignant tumors, seriously threatening physical and mental health women. Early detection early treatment can greatly reduce mortality "cytology /HPV test, colposcopy biopsy" is main method for clinical diagnosis cancer. The progress medical technology has significantly improved cancer, but due to various factors, there are still many cases missed misdiagnosis. In recent years, artificial intelligence developed rapidly in...
Hypoxic environment is a bottleneck of photodynamic therapy (PDT) in tumor treatment, as oxygen the critical substrate for photosensitivity reaction. Herein, sustained supply system based on cerium nanoparticles and hydrogel (GHCAC) was explored enhanced synergistic PDT gas therapy. Ceria were prepared drug carrier by self-assembly mediated hyaluronic acid (HA), targeting CD44 cervical cancer cells, followed photosensitizer l-arginine (l-Arg) loading. Then, GHCAC developed incorporating...
Piezoelectric devices based on a variety of vibration modes are widely utilized in high-tech fields to make conversion between mechanical and electrical energies. The excitation single or coupled piezoelectric is mainly related the structure property materials. However, for generally used materials, e.g., lead zirconate titanate ceramics, most coefficients matrix equal zero, resulting many cannot be excited, which hinders design devices. In this work, an orderly stacked with strain units...
ABSTRACT Background Advances in imaging technology have enhanced the detection of pulmonary nodules. However, determining malignancy often requires invasive procedures or repeated radiation exposure, underscoring need for safer, noninvasive diagnostic alternatives. Analyzing exhaled volatile organic compounds (VOCs) shows promise, yet its effectiveness assessing nodules remains underexplored. Methods Employing a prospective study design from June 2023 to January 2024 at Affiliated Hospital...
A displacement-dependent self-centering variable friction damper (DSVFD) was proposed to mitigate the residual displacement of structures following seismic events by utilizing capabilities a disc spring group and energy dissipation features stepped plate. Cyclic loading tests coupled with finite element analyses were conducted examine impacts plate preload, amplitude, number cycles on damper's behaviors. These findings suggest that increasing preload improves capacity damper, although it...
The direct construction of polycyclic arenes through ring formation using simple building blocks is highly appealing but remains challenging in organic chemistry. In this study, we introduce an efficient cascade reaction that combines dearomatizing photocyclization with oxidative aromatization, driven by organophotocatalysis. Conducted under mild, transition‐metal‐free conditions, seamlessly converts styrene derivatives into a diverse array functionalized aromatic compounds good yields and...
Geothermal reservoir rocks have the characteristics of high stress, hardness and abrasiveness, which makes drilling rate low cost high, hinders application geothermal energy. Improving efficiency in hard rock strata is prerequisite for large-scale Impact considered to be most effective method formations. PDC (Polycrystalline diamond Compact) bit compound impact one methods, has been widely concerned recent years. In order further improve this method, mechanism breaking studied....
PDC (polycrystalline diamond compact) drill bits are widely employed for rock-breaking in many industries like underground engineering and building constructions. The cutter layout would directly affect the overall performance of bits. Field applications show that staggered strategy dual-cutter can increase drilling efficiency bit. In order to explore rock breaking mechanism this type bit, a numerical model with damage evolution based on hybrid finite cohesive element method (FCEM) has been...
We have developed an effective photochemical method for site-selective (hetero)arylation of polychlorinated heteroarenes. This approach eliminates the need transition metal catalysts and photosensitizers by relying on in situ formation unconventional electron donor-acceptor (EDA) complexes between two substrates a basic additive. Our protocol yields chlorine-containing biaryl heterocyclic compounds with high levels site-selectivity, which are significant importance both synthetic medicinal chemistry.
Abstract The synthesis of α‐tertiary amino acids (ATAAs), which are pivotal components in natural metabolism and pharmaceutical innovation, continues to attract significant research interest. Despite substantial advancements, the pursuit a facile, versatile, resource‐efficient methodology remains an area active development. In this work, we introduce visible light‐triggered three‐component reaction involving readily available nitrosoarenes, N ‐acyl pyrazoles, allyl or (bromomethyl)benzenes...
The application of ultra-high-pressure (UHP) water jets for rock slotting in the bottom hole has been recognized as a highly effective approach to enhance rock-breaking efficiency. However, current downhole intensifiers are confronted with various limitations, including short duration UHP pulse jet output and challenges attaining both controllable adjustable frequencies, consequently leading compromised In this study, novel intensifier controlled by an electromagnetic valve was designed,...
How to improve drill bit working efficiency in deep drilling has been a wide concerned issue petroleum industry. Utilizing ultra-high-pressure water jet slot the bottom hole rock and reconfiguration stress field is considered an effective method enhance drillability rate of penetration. However, there currently no relevant report available on effect groove characteristics, which are important factors affecting break efficiency. Therefore, this study combines lab test with numerical...
In a household setting, wheelchair-mounted robotic arm (WMRA) can be useful for assisting elderly and disabled individuals. However, the current WMRA only perform movement grasping tasks through joystick remote control. This method results in low efficiency due to poor coordination between mobile platform as well numerous operational steps required. To improve success rate of robot task execution, this paper proposes parking location optimization that combines occupied grid map (OGM) inverse...
