Deep learning-based inverse design optimization of efficient multilayer thermal emitters in the near-infrared broad spectrum.

This study proposes a deep learning architecture for automatic modeling and optimization of multilayer thin film structures to address the need for specific spectral emitters and achieve rapid design of geometric parameters for an ideal spectral response. Multilayer film structures are ideal thermal emitter structures for thermophotovoltaic application systems because they combine the advantages of large area preparation and controllable costs. However, achieving good spectral response performance requires stacking more layers, which makes it more difficult to achieve fine spectral inverse design using forward calculation of the dimensional parameters of each layer of the structure.

A comparison between the low back pain scales for patients with lumbar disc herniation: validity, reliability, and responsiveness.

Background: Although the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ), Numerical Pain Rating Scale (NPRS), Oswestry Disability Index (ODI), Roland Morris Disability Questionnaire (RMDQ), and Short Form 36 Health Survey (SF-36) has shown a preferable psychometric properties in patients with low back pain (LBP), but no study has yet determined these in conservative treatment of patients with lumbar disc herniation (LDH). Thus the current study aimed to compare those scales in LDH patients receiving conservative treatment to select the better option to assess the severity of disease.

Methods: LDH patients were invited to complete the JOABPEQ, NPRS, ODI, RMDQ, and SF-36 twice.

Responses transition in a monolayer Al-AlO nanoparticle-crystal due to oxidation.

Nanoparticle is a promising candidate for large scale fabrication of metamaterial. However, optical responses for metamaterial made of abound metal like Al can be thoroughly changed due to oxidization. Especially for nanoparticle whose aspect ratio is extremely high, oxidation usually occurs.

Nanoparticle-crystal towards an absorbing meta-coating.

In this paper, a double layer nanoparticle-crystal has been proposed, which shown incident and polarization angle, substrate independences for spectral absorptivity. Such phenomenon originates from the near-field light redistribution and excitation of internal collective oscillating. This kind of nanoparticle-crystal can be made of various types of metal with similar optical responses.

[Er3+:Yb3+ co-doped nanocrystals BaGd2ZnO5 of up-conversion optical temperature sensing].

By far, the most efficient upconversion nanocrystals luminescence materials BaGd2ZnO5: 4%Yb3+ , 1%Er3+, with stable chemical performance, were prepared by using Sol-gel method. XRD pattern shows that the sample is pure phase, belongs to the orthogonal crystals, and space group is Pbnm; SEM micrograph shows that the prepared sample of the morphology sized around 150 nm is evenly distributed. Samples with 971 nm semiconductor laser excitation produce a strong green emission, visible to the naked eye, and uponversion strength and pump energy relation n = 1.

[Effects of early application of Tuina treatment on quadriceps surface myoelectricity in patients after total knee arthroplasty: a randomized controlled trial].

Background: Total knee replacement surgery is commonly used in end-stage diseases of the knee. It is important for improving surgical efficacy and patient satisfaction by promoting early rehabilitation of patients and improving knee function.

Objective: To observe the effects of early application of Tuina treatment on quadriceps surface electromyography (EMG) in patients with rheumatoid arthritis having undergone total knee arthroplasty.

The expression of protein inhibitor of activated signal transducers and activators of transcription 3 in the evolutionary process of gastric cancer.

Objective: To study the expression of PIAS3 (protein inhibitor of activated signal transducers and activators of transcription 3) in the evolutionary process of gastric cancer.

Methods: Samples were taken from the endoscopic biopsy specimens of 125 patients. Gastric mucosal lesions were diagnosed in HE staining, and chronic atrophic gastritis (CAG) with intestinal metaplasia (IM) were distinguished in AB-PAS and HID-AB staining.

PIAS3 expression in human gastric carcinoma and its adjacent non-tumor tissues.

Objective: PIAS3 is the endogenous inhibitor of STAT3, which has been implicated in the pathogenesis of many cancers. However, the effect of PIAS3 on human tumors remains elusive. The aim of this article is to investigate the expression of PIAS3 in gastric carcinoma and its adjacent non-tumor tissues.

Imaging dynamic cell-cell junctional coupling in vivo using Trojan-LAMP.

To study the physiological regulation and function of cell-cell gap junction communication in vivo, we developed a bioconjugate of caged dye, named dextran-CANPE-HCC, for imaging cell coupling in small model organisms. In vitro, the compound was photolyzed efficiently with robust fluorescence enhancement. Dextran-CANPE-HCC delivered into Caenorhabditis elegans oocytes was retained in cells throughout development.

Chiroptical transcription of helical information through supramolecular harmonization with dynamic helices.

With biologically important "peptide bundling" as the motif, new chromophoric cyclic host 1 was designed, which consists of two zinc porphyrin units that are connected by dynamic peptide helices of nonameric aminoisobutyric acid (Aib) units. Upon inclusion of pyridine-anchored helical peptides between the zinc porphyrin units, 1 displayed an intense exciton-coupled circular dichroism (CD) band at 410-450 nm, whose sign reflected the helical sense of the guest peptides. Studies with conformationally defined dehydrophenylalanine-containing analogues indicated that the dynamic helical chains in the host are stereochemically harmonized with right- or left-handed helices of the guest peptides in a confined nano space, leading to either clockwise- or anticlockwise-twisted geometry (chiroptical output) of the connecting zinc porphyrin chromophores.
