Micro-light-emitting diodes（μLEDs） have gained significant interest as an activation source for gas sensors owing to their advantages, including room temperature operation and low power consumption. however, despite these benefits, challenges still exist such as a limited range of detectable gases and slow response. In this study, we present a blue μLED-integrated light-activated gas sensor array based on SnO2nanoparticles（NPs） that exhibit excellent sensitivity, tunable selectivity, and rapid detection with micro-watt level power consumption. The optimal power for μLED is observed at the highest gas response, supported by finite-difference time-domain simulation. Additionally, we first report the visible light-activated selective detection of reducing gases using noble metal-decorated SnO2NPs. The noble metals induce catalytic interaction with reducing gases, clearly distinguishing NH3, H2, and C2H5OH. Real-time gas monitoring based on a fully hardwareimplemented light-activated sensing array was demonstrated, opening up new avenues for advancements in light-activated electronic nose technologies.

作者： jang ho Cho jae Yun Lim jae Yong Cho Division of Medical Oncology Department of Internal Medicine Gangnam Severance Hospital Yonsei University College of Medicine

AIM To investigate human epidermal growth factor 2(HER2) overexpression and validate its prognostic effect in stage Ⅱ-Ⅲ gastric *** We reviewed the data of patients who were diagnosed with gastric cancer between March 2008 and October 2013 at the Yonsei University Medical Center. Among these patients, 384 patients who met the inclusion criteria were analyzed retrospectively. RESULTS Thirty-two(8.3%) of the 384 stage Ⅱ-Ⅲ gastric cancer patients exhibited HER2 overexpression. The median follow-up duration was 26.0 mo. HER2-negative patients had superior recurrence-free survival(RFS) compared to HER2-positive patients(HR = 0.52, 95%CI: 0.30-0.89; P = 0.015). The median overall survival(OS) was significantly prolonged in the HER2-negative group compared with the HER2-positive group(55.0 mo vs 38.0 mo, HR = 0.43, 95%CI: 0.21-0.88, P = 0.021). OS was also prolonged in HER2-negative patients who received adjuvant chemotherapy compared to HER2-positive patients(55.0 vs 38.0mo, HR = 0.42, 95%CI: 0.18-1.00, P = 0.051). In patients who did not receive adjuvant chemotherapy,the median RFS was prolonged in the HER2-negative group compared to the HER2-positive group(not reached vs 12.0 mo, HR = 0.17, 95%CI: 0.06-0.49, P= 0.001). In a multivariate analysis, HER2 status(HR= 0.421, 95%CI: 0.206-0.861, P = 0.018) and Eastern Cooperative Oncology Group performance status(HR = 2.002, 95%CI: 1.530-2.618, P howed that HER2-positive patients had inferior OS and RFS. Stage Ⅱ-Ⅲ HER2-positive patients might be potential candidates for targeted therapies involving trastuzumab.

AIM: To assess the adhesion- and abscess-reducing capacities of various concentrations of polysaccharides derived from fungus, Phellinus gilvus (PG) or Phellinus linteus (PL) in a rat peritonitis ***: In 96 SD rats, experimental peritonitis was induced using the cecal ligation and puncture model (CLP).Rats were randomly assigned to 8 groups; Ringer's lactate solution (RL group), hyaluronic acid (HA group), 0.025%,0.25%, and 0.5% polysaccharides from PG (PG0.025, 0.25,and 0.5 groups), and PL (PL0.025, 0.25, and 0.5 groups).Adhesions and abscesses were noted at 7 d after ***-PCR assay was performed to assess the cecal ***: Adhesion formation was significantly reduced in PG0.25, 0.5, PL0.25, 0.5, and HA groups (2.5±0.7,2.4±0.7, 3.8±1.0, 3.6±0.8, and 2.7±1.1, P＜0.05). The incidence of abscesses was significantly reduced in all treated groups compared to RL group (58%, P＜0.05). The urokinase-type plasminogen activator (uPA) gene expression was greatly up-regulated by increasing the concentration of polysaccharides. The urokinase-type plasminogen activator receptor (uPAR) and tumor necrosis factor (TNF)-α mRNA were highly expressed in PG0.25, 0.5, PL0.25, and ***: We concluded that 0.5% polysaccharide derived from PG and PL was the optimal concentration in preventing adhesion and abscess formation and may act by modulating activity of uPA and TNF-α in a rat peritonitis model.

Unification of Gravitational and Strong Interaction Fields Using Partial Gauge Symmetry

引用

Journal of High Energy Physics, Gravitation and Cosmology 2024年第2期10卷 515-533页

作者： Young Hwan Yun Kiho jang Zero Theoretical Physics Lab Seoul Republic of Korea

We propose the new field potential by maintaining both the symmetry of the scalar gauge and the conservation law keeping N?ether’s theorem, while disregarding the symmetry of the vector gauge. The new potential forms like the well-type potential where a particle behaves almost freely but is very hard to escape without external energy, which can be interpreted as local confinement and asymptotic freedom. By assuming a 2-dimensional metric tensor in 4-dimensional space-time, we suggest the existence of 3 kinds of particles that resemble QCD with 3 color charges. We also show that the mass term exists but comes to zero and derive the charge and spin values. We can regard the particle with this new potential as a gluon, and the interaction in this well-type potential as a strong interaction for the properties of mass, charge, spin, and its behavior. We suggest the eight-fold way with this new particle, which is similar to the existing method based on SU (3) symmetry. Even though the strong interaction has been analyzed in the standard model and string theory, we build a new consistent model based on the theory of relativity including Riemann geometry, and show the unification of gravitational and strong interactional field.
