Higher temperature variability in deforested mountain regions impacts the competitive advantage of nocturnal species

Sheng-Feng Shen, Shih-Fan Chan, Dustin R. Rubenstein, I-Ching Chen, Yu-Meng Fan & Yuan-Wen Zheng
Deforestation is a primary cause of biodiversity loss. However, we know little about its effects on global patterns of daily microclimate variation, which can differentially impact species with different daily activity patterns. Using a recently developed microclimate model, we show that deforestation causes an increase in the diurnal temperature range (DTR) in lowland habitats at low latitudes and the mountains at high latitudes. Furthermore, we investigate competitive interactions between nocturnal burying beetles and all-day active...

Methods: Structured questionnaires and broadband ultrasound attenuation (BUA) data were obtained in 2009–2010 using QUS-C,...

Mechanisms of exchange flow in an estuary with a narrow, deep channel and wide, shallow shoals

W. Rockwell Geyer, David Ralston & Jia-Lin Chen
Delaware Bay is a large estuary with a deep, relatively narrow channel and wide, shallow banks, providing a clear example of a “channel-shoal” estuary. This numerical modeling study addresses the exchange flow in this channel-shoal estuary, specifically to examine how the lateral geometry affects the strength and mechanisms of exchange flow. We find that the exchange flow is exclusively confined to the channel region during spring tides, when stratification is weak, and it broadens laterally...

Data from: PbbHLH4 regulates floral monoterpene biosynthesis in Phalaenopsis orchids

Yu-Chen Chuang, Yi-Chu Hung, Wen-Chieh Tsai, Wen-Huei Chen & Hong-Hwa Chen
Floral scent is an important factor in attracting pollinators and repelling florivores. In Phalaenopsis bellina (Orchidaceae), the major floral scent components are monoterpenoids. Previously, we have identified that expression of GERANYL DIPHOSPHATE SYNTHASE (PbGDPS) is highly correlated with monoterpene biosynthesis in Phalaenosis orchids. Here, we showed that both cis- and trans-regulation were present on the GDPS promoters, with trans-regulation playing a key role. To investigate the regulation of floral scent biosynthesis, we compared the transcriptomic...

Main outcome measures: State HIV ASDR using 4 SPs, namely WHO2000, US2000, US2mor020, and Eur2011–2030. Results: The rankings of 19 states did not change when ASDRs were calculated using US2000 and US2020. Of the...

The role of vein grafts in reconstructive head and neck microsurgery

Chih-Sheng Lai, Yi-Ting Chang, Ching-Hui Shen, Yueh-Chi Tsai, Chen-Te Lu, Jung-Hsing Yen, I-Chen Chen & Yi-Ling Lin
Abstract Objective: Free tissue transfer is widely used for head and neck reconstruction. In certain circumstances, vein grafting is required to elongate free flap pedicles to connect them to appropriate recipient vessels. Because of controversy regarding the use of interposition vein grafts in free tissue reconstruction, this paper reports vein graft indications, techniques, safety, and outcomes for head and neck microvascular surgery. Methods: Twenty-six patients (23 men and 3 women) who underwent interposition vein grafting...

Data from: Biogeography of the Phalaenopsis amabilis species complex inferred from nuclear and plastid DNAs

Chi-Chu Tsai, Chang-Hung Chou, Hao-Ven Wang, Ya-Zhu Ko, Tzen-Yuh Chiang & Yu-Chung Chiang
Background: Phalaenopsis is one of the important commercial orchids in the world. Members of the P. amabilis species complex represent invaluable germplasm for the breeding program. However, the phylogeny of the P. amabilis species complex is still uncertain. The Phalaenopsis amabilis species complex (Orchidaceae) consists of subspecies amabilis, moluccana, and rosenstromii of P. amabilis, as well as P. aphrodite ssp. aphrodite, P. ap. ssp. formosana, and P. sanderiana. The aims of this study were to...

Geometric structure and electronic properties of boron-substituted silicene

Ming-Fa Lin
The essential properties of monolayer silicene greatly enriched by boron substitutions are thoroughly explored through first -principles calculations. Delicate analyses are conducted on the highly non-uniform Moire superlattices, atom-dominated band structures, charge density distributions and atom- & orbital-decomposed van Hove singularities. The hybridized 2pz-3pz and [2s, 2px, 2py]-[3s, 3px, 3py] bondings, with orthogonal relations, are obtained from the developed theoretical framework. The red-shifted Fermi level and the modified Dirac cones/π bands/σ bands are clearly identified...

Data from: Development of an intravascular ultrasound elastography based on a dual-element transducer

Cho-Chiang Shih, Pei-Yu Chen, Teng Ma, Qifa Zhou, K. Kirk Shung & Chih-Chung Huang
The ability to measure the elastic properties of plaques and vessels would be useful in clinical diagnoses, particularly for detecting a vulnerable plaque. This study demonstrates the feasibility of combination of intravascular ultrasound (IVUS) and acoustic radiation force (ARF) elasticity imaging for detecting the distribution of stiffness within atherosclerotic arteries ex vivo. A dual-frequency IVUS transducer with two elements was used to induce the propagation of shear wave (by the 8.5-MHz pushing element) which could...

Semi-Siamese U-Net for separation of lung and heart bioimpedance images: a simulation study of thorax EIT

Yen Fen KO
Electrical impedance tomography (EIT) is widely used for bedside monitoring of lung ventilation status. Its goal is to reflect the internal conductivity changes and estimate the electrical properties of the tissues in the thorax. However, poor spatial resolution affects EIT image reconstruction to the extent that the heart and lung-related impedance images are barely distinguishable. Several studies have attempted to tackle this problem, and approaches based on decomposition of EIT images using linear transformations have...

Data from: RockNet: Rockfall and earthquake detection and association via multitask learning and transfer learning

Wu-Yu Liao, En-Jui Lee, Chung-Ching Wang, Po Chen, Floriane Provost, Clément Hibert & Jean-Philippe Malet
Seismological data can provide timely information for slope failure hazard assessments, among which rockfall waveform identification is challenging for its high waveform variations across different events and stations. A rockfall waveform does not have typical body waves as earthquakes do, so researchers have made enormous efforts to explore characteristic function parameters for automatic rockfall waveform detection. With recent advances in deep learning, algorithms can learn to automatically map the input data to target functions. We...

Data from: Incorporating an ontogenetic perspective into evolutionary theory of sexual size dimorphism

Chun-Chia Chou, Yoh Iwasa & Takefumi Nakazawa
Sexual size dimorphism (SSD) describes divergent body sizes of adult males and females. While SSD has traditionally been explained by sexual and fecundity selection, recent advances in physiology and developmental biology emphasize that SSD would occur proximately because of sexual differences in ontogenetic growth trajectories (i.e., growth rate and duration). Notably, these ontogenetic traits are subject to energetic or time constraints and thus traded off with fitness components (e.g., survival and reproduction). To elucidate the...
