Solitons in microresonators have spurred intriguing nonlinear optical physics and photonic applications. Here, by combining Kerr and Brillouin nonlinearities in an over-modal microcavity, we demonstrate spatial multiplexing of soliton microcombs under a single external laser pumping operation. This demonstration offers an ideal scheme to realize highly coherent dual-comb sources in a compact, low-cost and energy-efficient manner, with uniquely low beating noise. Moreover, by selecting the dual-comb modes, the repetition rate difference of a dual-comb pair could be flexibly switched, ranging from 8.5 to 212 MHz. Beyond dual-comb, the high-density mode geometry allows the cascaded Brillouin lasers, driving the co-generation of up to 5 space-multiplexing frequency combs in distinct mode families. This Letter offers a novel physics paradigm for comb interferometry and provides a widely appropriate tool for versatile applications such as comb metrology, spectroscopy, and ranging.

With the increase of compression ratio, the popularization of bioethanol and the development of NO_x emission control technologies for lean combustion, it is easier to realize high-efficiency and clean SICI combustion under medium-to-high load. Combining split injection with various excess air ratio (\u03bb), the effects of ethanol in fuels with the same RON value (93# and 80#E15) on combustion characteristics, indicated thermal efficiency and PN emissions were investigated in a high compression ratio (15.5), single-cylinder, four-stroke engine. For comparison, the performance of pure anhydrous ethanol (E100) was also studied in this engine. The results show that ethanol-contained fuels can accelerate the flame propagation but suppress the heat release rate (HRR) of autoignition, and autoignition does not even exist in E100 combustion. Consequently, CA50 is advanced but combustion duration is prolonged for ethanol-contained fuels. It is highlighted that the predominant contribution of ethanol in improving the indicated thermal efficiency is the optimization of CA50 rather than the combustion iso-volume. In addition, the knock intensity is effectively suppressed, and the combustion process can be optimized by split injection with appropriate EOI2 (the end of the second injection) and split ratio for gasoline and ethanol-blended fuel, which further improve the indicated thermal efficiency. PN emissions exhibit a generally positive correlation with knock intensity in SICI mode and SICI mode can reduce the particles generated by the spray-wall impingement and ultra-rich mixture near the wall. Lean combustion can simultaneously suppress flame propagation and autoignition and is more effective in PN emissions reduction for fuels of 93# and 80#E15 within the cycle-to-cycle variation (COV) limitation rather than E100. However, E100 demonstrates two orders of PN emissions smaller than 93# and 80#E15 due to its high oxygen fraction content.", "doi": "10.1016/j.fuel.2022.123155", "issn": "0016-2361", "publisher": "Elsevier", "publication": "Fuel", "publication_date": "2022-05-15", "volume": "316", "pages": "Art.

However, TMDCs exhibit poor emission efficiency due to defect states and direct-to-indirect interband transition, and 2DPVSKs suffer from poor stability in ambient atmosphere. Here we report that fabrication of TMDC-on-2DPVSK heterostructures using a solvent-free process leads to novel optical transitions unique to the heterostructure which arise from the hybrid interface and exhibit a strong photoluminescence. Moreover, a two orders of magnitude enhancement of the photoluminescence as compared to WS_2 emission is observed. The TMDC on top of 2DPVSK also significantly improves the stability as compared to bare 2DPVSK. Enhanced emission can be explained by electronic structure modification of TMDC by novel interfacial interactions between TMDC and 2DPVSK materials, which shows promise of the heterostructure for high efficiency and stable optoelectronic devices.", "doi": "10.1021/acs.nanolett.8b05105", "issn": "1530-6984", "publisher": "American Chemical Society", "publication": "Nano Letters", "publication_date": "2019-08-14", "series_number": "8", "volume": "19", "issue": "8", "pages": "4852-4860" }, { "id": "authors:h28er-knm85", "collection": "authors", "collection_id": "h28er-knm85", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20190311-132001293", "type": "article", "title": "Optical orbital-angular-momentum-multiplexed data transmission under high scattering", "author": [ { "family_name": "Gong", "given_name": "Lei", "orcid": "0000-0002-0995-5781", "clpid": "Gong-Lei" }, { "family_name": "Zhao", "given_name": "Qian", "orcid": "0000-0001-6939-3568", "clpid": "Zhao-Qian" }, { "family_name": "Zhang", "given_name": "Hao", "clpid": "Zhang-Hao" }, { "family_name": "Hu", "given_name": "Xin-Yao", "clpid": "Hu-Xin-Yao" }, { "family_name": "Huang", "given_name": "Kun", "clpid": "Huang-Kun" }, { "family_name": "Yang", "given_name": "Jia-Miao", "clpid": "Yang-Jia-Miao" }, { "family_name": "Li", "given_name": "Yin-Mei", "clpid": "Li-Yin-Mei" } ], "abstract": "Multiplexing multiple orbital angular momentum (OAM) channels enables high-capacity optical communication.

All functional annotations for proteins and non-protein-coding RNA (npRNA) candidates were manually curated. Functions were identified or inferred in 19,969 (70%) of the proteins, and 131 possible npRNAs (including 58 antisense transcripts) were found. Almost 5000 annotated protein-coding genes were found to be disrupted in insertional mutant lines, which will accelerate future experimental validation of the annotations. The rice loci were determined by using cDNA sequences obtained from rice and other representative cereals. Our conservative estimate based on these loci and an extrapolation suggested that the gene number of rice is ~32,000, which is smaller than previous estimates. We conducted comparative analyses between rice and Arabidopsis thaliana and found that both genomes possessed several lineage-specific genes, which might account for the observed differences between these species, while they had similar sets of predicted functional domains among the protein sequences. A system to control translational efficiency seems to be conserved across large evolutionary distances. Moreover, the evolutionary process of protein-coding genes was examined. Our results suggest that natural selection may have played a role for duplicated genes in both species, so that duplication was suppressed or favored in a manner that depended on the function of a gene.", "doi": "10.1101/gr.5509507", "issn": "1088-9051", "publisher": "Cold Spring Harbor Laboratory Press", "publication": "Genome Research", "publication_date": "2007-02", "series_number": "2", "volume": "17", "issue": "2", "pages": "175-183" }, { "id": "authors:v24vh-fm583", "collection": "authors", "collection_id": "v24vh-fm583", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20180927-114227162", "type": "book_section", "title": "Acousto-electric tomography", "book_title": "Photons Plus Ultrasound: Imaging and Sensing", "author": [ { "family_name": "Zhang", "given_name": "Hao", "clpid": "Zhang-Hao" }, { "family_name": "Wang", "given_name": "Lihong V.", "orcid": "0000-0001-9783-4383", "clpid": "Wang-Lihong-V" } ], "contributor": [ { "family_name": "Oraevsky", "given_name": "Alexander A.", "clpid": "Oraevsky-A-A" }, { "family_name": "Wang", "given_name": "Lihong V.", "clpid": "Wang-Lihong-V" } ], "abstract": "Although the electric impedance of biological tissues is highly sensitive to their physiological and pathological status, pure electrical impedance tomography (EIT) has very poor spatial resolution. We invented acousto-electric tomography (AET) to image the electric impedance properties of biological tissues with high spatial resolution. AET is based on acousto-electric modulation, which is the localized variation in conductivity produced by a focused ultrasonic wave. It combines the contrast advantage of EIT and the resolution advantage of ultrasound imaging. The spatial resolution of AET is primarily defined by the size of the ultrasonic focal spot. Therefore, the resolution is much better than that of EIT, and it is scalable with the acoustic parameters. The contrast of AET is determined by the combination of three factors: the electric impedance, the media dependent modulation coefficient, and the acoustic properties. Unlike EIT, AET forms images directly without resorting to inverse algorithms. And unlike traditional ultrasonography, AET is free of speckles.", "doi": "10.1117/12.532610", "isbn": "9780819452283", "publisher": "Society of Photo-optical Instrumentation Engineers (SPIE)", "place_of_publication": "Bellingham, WA", "publication_date": "2004-07-12", "pages": "145-149" } ]
