On the C-E Translation of Chinese Classics from the Perspective of Thick Translation Theory
Thick translation theory was put forward by Appiah, an American translation theorist, concerning the cultural information dissemination and cultural significance of a deep description. Based on the English translation version of Six Chapters of a Floating Life, the study analyses the manifestation of traditional Chinese culture and methods to translate Chinese classic words from the perspective of “thick translation” theory, in an attempt to verify the operability of the theory in the translation of Chinese classics
On the Compensation Strategies for Museum Texts —A Case Study of the Archaeological Excavations at the Royal Cemetery of Haihunhou Kingdom in the Han Dynasty
As a momentous material for carrying and promoting culture, museum texts contain not only abundant information but also profound cultural implication. Along with the development of modern linguistics theories and their related disciplines, modern translation compensation research is also constantly gaining momentum. Through analyzing the translation of archaeological exhibitions of the Han Dynasty in Nanchang, this paper deals with the characteristics of the museum texts and its translation compensation strategies with a view to providing a new research approach for the future translation practice of museum texts.

Effects of magnetic field on thermo-hydraulic performance of Fe3O4-water nanofluids in a corrugated tube
© 2018 Elsevier Ltd An experimental system is established to investigate the thermo-hydraulic performance of Fe3O4-water nanofluids in a corrugated tube under various magnetic fields. The influences of magnetic induction intensities (B = 0 G, 100 G, 200 G, 300 G), nanoparticle mass fractions (ω = 0.0%, 0.1%, 0.3%, 0.5%), electromagnet arrangement modes (one-side electromagnet and two-side staggered electromagnet), kinds of tubes (smooth tube and corrugated tube), Reynolds numbers (Re = 800–12,000) on flow and heat transfer characteristics are discussed. It is obtained that the augmentation of heat transfer is more sensitive to high nanoparticle mass fraction, high magnetic induction intensity, two-side staggered electromagnet and corrugated tube. A Comprehensive evaluation index is applied to estimate the thermo-hydraulic performance. It can be discovered that the comprehensive evaluation index increases with the increasing Reynolds number at first and then decreases, and the rough surface of corrugated tube delays the appearance of critical Reynolds number
Giant perivascular spaces: two case reports
Giant perivascular spaces or Virchow-Robin spaces (VRSs) are uniquely inherent developmental malformation and are generally lined by ependymal or leptomeningeal cells. The cerebral hemispheres with VRSs present multiple cysts of curvilinear, round, oval, or layered configuration, which have the same signal intensity as the cerebrospinal fluid (CSF) and represent extremely dilated VRSs. The cortex became extremely thin with a well-defined margin. Herein, we report two cases of true giant perivascular spaces and present a review of pertinent literature. A patient has multiple cysts in the unilateral and bilateral and has polycystic liver. The clinical presentation, image logical features, and diagnosis are discussed
Photothermal conversion and transfer in photothermal therapy: From macroscale to nanoscale
Photothermal therapy (PTT) is a promising alternative therapy for benign or even malignant tumors. To improve the selective heating of tumor cells, target-specific photothermal conversion agents are often included, especially nanoparticles. Meanwhile, some indirect methods by manipulating the radiation and heat delivery are also adopted. Therefore, to gain a clear understanding of the mechanism, and to improve the controllability of PTT, a few issues need to be clarified, including bioheat and radiation transfer, localized and collective heating of nanoparticles, etc. In this review, we provide an introduction to the typical bioheat transfer and radiation transfer models along with the dynamic thermophysical properties of biological tissue. On this basis, we reviewed the most recent advances in the temperature control methods in PTT from macroscale to nanoscale. Most importantly, a comprehensive introduction of the localized and collective heating effects of nanoparticle clusters is provided to give a clear insight into the mechanism for PPT from the microscale and nanoscale point of view
Nanoparticle hybrids as efficient theranostic nanoagents with enhanced near-infrared optical absorption and scattering
The design of high-efficiency theranostic nanoagents that can be utilized in tumor diagnosis and treatment has been investigated extensively in recent years. However, most of the existing nanoagents consist of uncommon materials and complex shell structures. Despite the efforts that have been made, the development of a simple and easily synthesized theranostic nanoplatform that can be applied in optical-based imaging-guided photothermal therapy still remains a challenge. In this paper, we investigated the optical characteristics of nanoparticle aggregates as potential theranostic nanoplatforms. The mechanism of spectrum shifting and the optical properties of contacting and non-contacting short nanochains were investigated. It was found that the near-field interaction of the gold nanosphere will not shift the localized surface plasmon resonance peak to the near-infrared region. However, when the nanospheres are connected to each other, a low energy resonance peak will be excited. On this basis, a simple hybrid theranostic nanoagent consisting of different nanosphere clusters was proposed. The nanohybrid exhibits high absorption and low scattering in the first near-infrared window (NIR-I) and high scattering and near-zero absorption in the second NIR (NIR-II). This characteristic can be beneficial to tumor diagnosis and treatment, i.e., NIR-I for photothermal therapy and NIR-II for optical imaging. Numerical results show that the performance of the proposed hybrid theranostic nanoagent remains excellent even with the existence of potential impuritie
Neural Cognitive Diagnosis for Intelligent Education Systems
Cognitive diagnosis is a fundamental issue in intelligent education, which
aims to discover the proficiency level of students on specific knowledge
concepts. Existing approaches usually mine linear interactions of student
exercising process by manual-designed function (e.g., logistic function), which
is not sufficient for capturing complex relations between students and
exercises. In this paper, we propose a general Neural Cognitive Diagnosis
(NeuralCD) framework, which incorporates neural networks to learn the complex
exercising interactions, for getting both accurate and interpretable diagnosis
results. Specifically, we project students and exercises to factor vectors and
leverage multi neural layers for modeling their interactions, where the
monotonicity assumption is applied to ensure the interpretability of both
factors. Furthermore, we propose two implementations of NeuralCD by
specializing the required concepts of each exercise, i.e., the NeuralCDM with
traditional Q-matrix and the improved NeuralCDM+ exploring the rich text
content. Extensive experimental results on real-world datasets show the
effectiveness of NeuralCD framework with both accuracy and interpretability
Persistent Josephson tunneling between BiSrCaCuO flakes twisted by 45 across the superconducting dome
There is a heated debate on the Josephson effect in twisted
BiSrCaCuO flakes. Recent experimental results suggest the
presence of either anomalously isotropic pairing or exotic +i-wave
pairing, in addition to the commonly believed -wave one. Here, we address
this controversy by fabricating ultraclean junctions with uncompromised
crystalline quality and stoichiometry at the junction interfaces. In the
optimally doped regime, we obtain prominent Josephson coupling (2-4 mV) in
multiple junctions with the twist angle of 45, in sharp contrast to a
recent report that shows two orders of magnitude suppression around 45
from the value at 0. We further extend this study to the previously
unexplored overdoped regime and observe pronounced Josephson tunneling at
45 together with Josephson diode effect up to 50 K. Our work helps
establish the persistent presence of an isotropic pairing component across the
entire superconducting phase diagram.Comment: 6 pages, 5 figure
Effects of turbulator with round hole on the thermo-hydraulic performance of nanofluids in a triangle tube
© 2019 Elsevier Ltd For investigating the thermal and hydraulic characteristics of water-based SiO2 nanofluids in a triangular tube with different turbulators, an experimental system has been designed and verified in this paper. The effects of different round hole diameters (d = 3 mm, 4 mm, 5 mm) and round hole pitch-rows (l = 5 cm, 10 cm, 15 cm) of perforated turbulators on the thermo-hydraulic characteristics are researched. Meanwhile, the influences of Reynolds numbers (Re = 400–8000) and nanoparticles mass fractions (D-I water, ω = 0.1%, 0.3%, 0.5%) are also studied. These experimental results show that, under the same circumstance, the nanofluids in the triangular tube with ω = 0.5% have the largest positive influence on the heat transfer enhancement ratio which is up to 16.73%. For a comprehensive study of the flow and heat transfer, thermal efficiency (comprehensive performance index) and exergy efficiency are adopted. It can be found that the larger the diameter and the smaller the pitch-row of the holes is, the greater the comprehensive evaluation index can be. In addition, all working conditions exhibit the superior exergy efficiency. The highest exergy efficiency can be got when Re = 6000 and ω = 0.5%
