Impact of the Gate Width of Al 0.27
This paper presents impact of layout sizes of Al0.27Ga0.73N/AlN/Al0.04Ga0.96N/GaN HEMT heterostructure high-mobility transistors (HEMTs) on SiC substrate on its characteristics that include the threshold voltage, the maximum transconductance, characteristic frequency, and the maximum oscillation frequency. The changing parameters include the gate finger number, the gate width per finger. The measurement results based on common-source devices demonstrate that the above parameters have different effects on the threshold voltage, maximum transconductance, and frequency characteristics
An ab initio investigation of nickel (II) complexes with water, chloride, hydroxide and ammonia
130 leaves : col. ill. ; 29 cm. + 1 computer diskIncludes abstract and appendix.Includes bibliographical references (leaves 122-130).CD-ROM in pocket contains supplementary materials.One of the main undesirable processes in Supercritical Water-Cooled Reactors (SCWR) is the possible formation of metal ligand complexes from ions present in coolant which is very poorly understood both experimentally and theoretically. As pressurized and heated solutions are difficult to work with, computational methods have now become an important research tool in this respect. A series of ab initio calculations of nickel(II) with hydroxide, ammonia, water and chloride have been performed at HF, MP2 and B3LYP levels with 6-31+G* basis sets. A thorough examination of geometries, energies and vibrational frequencies has been carried out for all species up to and including hexacoordinate species. The computational results are compared with experimental data where available
Institutional quality, financial development and OFDI
AbstractUsing a panel of 73 countries from 2000 to 2008, this study uses Investment Development Path theory as a framework that utilises institutional quality (IQ) as a threshold for the effect of economic development on OFDI. Using the dynamic threshold model, we find new evidence that the strong promoting effect is initiated when IQ is within a certain interval, which is supplementary to IDP theory. Finally, we propose the corresponding advice
Beyond Triplet: Leveraging the Most Data for Multimodal Machine Translation
Multimodal machine translation (MMT) aims to improve translation quality by
incorporating information from other modalities, such as vision. Previous MMT
systems mainly focus on better access and use of visual information and tend to
validate their methods on image-related datasets. These studies face two
challenges. First, they can only utilize triple data (bilingual texts with
images), which is scarce; second, current benchmarks are relatively restricted
and do not correspond to realistic scenarios. Therefore, this paper
correspondingly establishes new methods and new datasets for MMT. First, we
propose a framework 2/3-Triplet with two new approaches to enhance MMT by
utilizing large-scale non-triple data: monolingual image-text data and parallel
text-only data. Second, we construct an English-Chinese {e}-commercial
{m}ulti{m}odal {t}ranslation dataset (including training and testing), named
EMMT, where its test set is carefully selected as some words are ambiguous and
shall be translated mistakenly without the help of images. Experiments show
that our method is more suitable for real-world scenarios and can significantly
improve translation performance by using more non-triple data. In addition, our
model also rivals various SOTA models in conventional multimodal translation
benchmarks.Comment: 8 pages, ACL 2023 Findin

RNF169 limits 53BP1 deposition at DSBs to stimulate single-strand annealing repair
Unrestrained 53BP1 activity at DNA double-strand breaks (DSBs) hampers DNA end resection and upsets DSB repair pathway choice. RNF169 acts as a molecular rheostat to limit 53BP1 deposition at DSBs, but how this fine balance translates to DSB repair control remains undefined. In striking contrast to 53BP1, ChIP analyses of AsiSI-induced DSBs unveiled that RNF169 exhibits robust accumulation at DNA end-proximal regions and preferentially targets resected, RPA-bound DSBs. Accordingly, we found that RNF169 promotes CtIP-dependent DSB resection and favors homology-mediated DSB repair, and further showed that RNF169 dose-dependently stimulates single-strand annealing repair, in part, by alleviating the 53BP1-imposed barrier to DSB end resection. Our results highlight the interplay of RNF169 with 53BP1 in fine-tuning choice of DSB repair pathways
