Contrasting impacts of two types of El Niño events on winter haze days in China's Jing-Jin-Ji region
Authors: Yu Xiaochao , Wang Zhili , Zhang Hua , He Jianjun , Li Ying
Published: September 2020

Abstract. El Niño events differ widely in their patterns and intensities. The regional climate anomalies caused by different types of El Niño events
likely lead to various impacts on winter haze pollution in China. Based on long-term site observations of haze days in China from 1961 to 2013, this
study explores the effects of eastern Pacific (EP) and central Pacific (CP) types of El Niño events on the number of winter haze days (WHDs) in
China's Jing-Jin-Ji (JJJ) region and the physical mechanisms underlying WHD changes. The results show statistically significant positive and
negative correlations, respectively, between WHDs in the JJJ region and EP and CP El Niño events. At most sites in the JJJ region, the average
WHD increased in all EP El Niño years, with the maximum change exceeding 2.0 d. Meanwhile, the average WHD decreased at almost all
stations over this region in all CP El Niño years, with the largest change being more than −2.0 d. The changes in large-scale
circulations indicate obvious positive surface air temperature (SAT) anomalies and negative sea level pressure (SLP) anomalies over North China, as well as
southerly wind anomalies at the middle to low troposphere over eastern China in the winters of EP El Niño years. These anomalies are conducive to
increases in WHDs in the JJJ region. However, there are significant northerly and northwesterly wind anomalies at the middle to low troposphere over
eastern China, as well as stronger and wider precipitation anomalies in the winters of CP El Niño years, which contribute to decreased WHDs over the JJJ
region. Changes in local synoptic conditions indicate negative SLP anomalies, positive SAT anomalies, and weakened northerly winds over the JJJ
region in the winters of EP El Niño years. The total occurrence frequency of circulation types conducive to the accumulation (diffusion) of
aerosol pollutants is increased (decreased) by 0.4 % (0.2 %) in those winters. However, the corresponding frequency is decreased (increased)
by 0.5 % (0.6 %) in the winters of CP El Niño years. Our study highlights the importance of distinguishing the impacts of these two
types of El Niño events on winter haze pollution in China's JJJ region.
Quantifying burning efficiency in megacities using the NO2∕CO ratio from the Tropospheric Monitoring Instrument (TROPOMI)

Abstract. This study investigates the use of co-located nitrogen
dioxide (NO2)
and carbon monoxide (CO) retrievals from the TROPOMI satellite to improve the quantification
of burning efficiency and emission factors (EFs) over the megacities of Tehran,
Mexico City, Cairo, Riyadh, Lahore, and Los Angeles. Efficient combustion is
characterized by high NOx (NO+NO2) and low CO emissions, making the
NO2∕CO ratio a useful proxy for combustion efficiency (CE). The local
enhancement of CO and NO2 above megacities is well captured by TROPOMI
at short averaging times compared with previous satellite missions. In this
study, the upwind background and plume rotation methods are used to
investigate the accuracy of satellite-derived ΔNO2∕ΔCO
ratios. The column enhancement ratios derived using these two methods vary
by 5 % to 20 % across the selected megacities. TROPOMI-derived column
enhancement ratios are compared with emission ratios from the EDGAR v4.3.2 (Emission Database for Global Atmospheric Research v4.3.2)
and the MACCity (Monitoring Atmospheric
Chemistry and Climate and CityZen) 2018 emission inventories. TROPOMI correlates strongly (r=0.85 and 0.7) with EDGAR and MACCity, showing the highest emission ratio for
Riyadh and lowest emission ratio for Lahore. However, inventory-derived emission ratios are 60 % to 85 %
higher than TROPOMI column enhancement ratios across
the six megacities. The short lifetime of NO2 and the different vertical
sensitivity of TROPOMI NO2 and CO explain most of this difference. We
present a method to translate TROPOMI-retrieved column enhancement ratios
into corresponding emission ratios, thereby accounting for these influences. Except
for Los Angeles and Lahore, TROPOMI-derived emission ratios are close
(within 10 % to 25 %) to MACCity values. For EDGAR, however, emission ratios are ∼65 %
higher for Cairo and 35 % higher for Riyadh. For Los Angeles, EDGAR and MACCity are a factor of 2 and 3 higher
than TROPOMI respectively. The air quality monitoring networks in Los Angeles and
Mexico City are used to validate the use of TROPOMI. For Mexico City and Los
Angeles, these measurements are consistent with TROPOMI-derived emission
ratios, demonstrating the potential of TROPOMI with respect to monitoring burning
efficiency.

Abstract. Changes in engine technologies and after-treatment devices can profoundly alter the chemical composition of the emitted pollutants. To investigate these effects, we characterized the chemical composition of particles emitted from three diesel and four gasoline Euro 5 light duty vehicles on a chassis dynamometer facility. Black carbon (BC) was the dominant emitted species with emission factors (EFs) varying from 0.2 to 7.1 mg km−1 for gasoline cars and 0.003 to 0.08 mg km−1 for diesel cars. For gasoline cars, the organic matter (OM) EFs varied from 5 to 103 µg km−1 for direct injection (GDI) vehicles, and from 1 to 8 µg km−1 for port fuel injection (PFI) vehicles, while for the diesel cars it ranged between 0.15 and 65 µg km−1. Cold-start cycles and more specifically the first minutes of the cycle, contributed the largest fraction of the PM including BC, OM and Polycyclic Aromatic Hydrocarbons (PAHs). More than 40 PAHs, including methylated, nitro, oxygenated and amino PAHs were identified and quantified in both diesel and gasoline exhaust particles using an Aerodyne High Resolution Time-of-Flight Aerosol Mass Spectrometry (HR-ToF-AMS). The PAHs emissions from the GDI technology were a factor of 4 higher compared to the vehicles equipped with a PFI system during the cold start cycle, while the nitro-PAHs fraction was much more appreciable in the GDI emissions. For two of the three diesel vehicles the PAHs emissions were close to the detection limit, but for one, which presented an after-treatment device failure, the average PAHs EF was 2.04 µg km−1. Emissions of nanoparticles (below 30 nm), mainly composed by ammonium bisulfate, were measured during the passive regeneration of the catalyzed diesel particulate filter (CDPF) vehicle. TEM images confirmed the presence of ubiquitous nanometric metal inclusions into soot particles emitted from the diesel vehicle equipped with a fuel borne catalyst – diesel particulate filter (FBC-DPF). XPS analysis of the particles emitted by the PFI car revealed both the presence of heavy elements (Ti, Zn, Ca, Si, P, Cl), and disordered soot surface with a significant concentration of carbon radical defects having possible consequences on both chemical reactivity and particle toxicity. Our findings show that different after-treatment technologies have an important effect on the level and the chemical composition of the emitted particles. In addition, this research highlights the importance of the particle filter devices condition and their regular checking.
Progress and problems of gender equality in Japanese academics and geosciences
Authors: Hori Rie S.
Published: September 2020

Abstract. In its gender equality status, Japan lags behind the European Union (EU)
and other Organisation for Economic Co-operation and Development (OECD) countries. Only 16.7 % of academic staff in national
universities are women. Although there has been a slow improvement during
the last 45 years, the percentage of female staff remains particularly low
in the STEM (science, technology, engineering, and mathematics) fields. In 2018, female stuff accounted for only 12.3 % in
agriculture, 8.7 % in science, and 6.2 % in engineering. The number of
female graduate students and the number of female members of the Japanese
geoscience societies have been steadily increasing since the 1998 campaign
that increased the total number of graduate school places. However, low
representation of females in academic job positions, as well as among the
recipients of academic awards, suggests that a strong unconscious bias
against women still exists in Japan. Continuing public attention to these
issues is essential for the improvement of the situation.
Vegetation influence and environmental controls on greenhouse gas fluxes from a drained thermokarst lake in the western Canadian Arctic
Authors: Skeeter June , Christen Andreas , Laforce Andrée-Anne , Humphreys Elyn , Henry Greg
Published: September 2020

Abstract. Thermokarst features are widespread in ice-rich regions of the
circumpolar Arctic. The rate of thermokarst lake formation and
drainage is anticipated to accelerate as the climate warms. However,
it is uncertain how these dynamic features impact the terrestrial
Arctic carbon cycle. Methane (CH4) and carbon dioxide
(CO2) fluxes were measured during peak growing season using
eddy covariance and chambers at Illisarvik, a 0.16 km2
thermokarst lake basin that was experimentally drained in 1978 on
Richards Island, Northwest Territories, Canada. Vegetation in the
basin differs markedly from the surrounding dwarf-shrub tundra and
included patches of tall shrubs, grasses, and sedges with some bare
ground and a small pond in the centre. During the peak growing season,
temperature and wind conditions were highly variable, and soil water
content decreased steadily. Basin-scaled net ecosystem CO2
exchange (NEE) measured by eddy covariance was
−1.5 [CI95 %±0.2] g C−CO2 m-2d-1; NEE followed
a marked diurnal pattern with no day-to-day trend during the study
period. Variations in half-hourly NEE were primarily controlled by
photosynthetic photon flux density and influenced by vapour pressure
deficit, volumetric water content, and the presence of shrubs within
the flux tower footprint, which varied with wind direction. Net
methane exchange (NME) was low (8.7 [CI95 %±0.4] mgCH4m-2d-1) and had little impact on the
growing season carbon balance of the basin. NME displayed high spatial
variability, and sedge areas in the basin were the strongest source of
CH4 while upland areas outside the basin were a net
sink. Soil moisture and temperature were the main environmental
factors influencing NME. Presently, Illisarvik is a carbon sink during
the peak growing season. However, these results suggest that rates of
growing season CO2 and CH4 exchange rates may
change as the basin's vegetation community continues to evolve.
Modelling Silicate – Nitrate - Ammonium co-limitation of algal growth and the importance of bacterial remineralisation based on an experimental Arctic coastal spring bloom culture study

Published: September 2020

Abstract. Arctic coastal ecosystems are rapidly changing due to climate warming, which makes modelling their productivity crucially important to better understand future changes. System primary production in these systems is highest during the pronounced spring bloom, typically dominated by diatoms. Eventually the spring blooms terminate due to silicon or nitrogen limitation. Bacteria can play an important role for extending bloom duration and total CO2 fixation through ammonium regeneration. Current ecosystem models often simplify the effects of nutrient co-limitations on algal physiology and cellular ratios and neglect bacterial driven regeneration, leading to an underestimation of primary production. Detailed biochemistry- and cell-based models can represent these dynamics but are difficult to tune in the environment. We performed a cultivation experiment that showed typical spring bloom dynamics, such as extended algal growth via bacteria ammonium remineralisation, and reduced algal growth and inhibited chlorophyll synthesis under silicate limitation, and gradually reduced nitrogen assimilation and chlorophyll synthesis under nitrogen limitation. We developed a simplified dynamic model to represent these processes. The model also highlights the importance of organic matter excretion, and post bloom ammonium accumulation. Overall, model complexity is comparable to other ecosystem models used in the Arctic while improving the representation of nutrient co-limitation related processes. Such model enhancements that now incorporate increased nutrient inputs and higher mineralization rates in a warmer climate will improve future predictions in this vulnerable system.

Published: September 2020

Abstract. Increasing evidence from experimental studies suggests that the losses of semi-volatile vapors to the chamber walls could be responsible for the underestimation of organic aerosol (OA) in air quality models which use parameters obtained from the chamber experiments. In this study, a box model with volatility basis set (VBS) scheme was developed and the secondary organic aerosol (SOA) yields with vapor wall loss corrected were optimized by a genetic algorithm based on advanced chamber experimental data for biomass burning. The vapor wall loss correction increases the SOA yields by a factor of 1.9–4.9, and leads to a better agreement with the measured OA for 14 chamber experiments under different temperatures and emission loads. To investigate the influence of vapor wall loss correction on regional OA simulations, the optimized parameterizations (SOA yields, emissions of intermediate-volatility organic compounds from biomass burning, and enthalpy of vaporization) were implemented in the regional air quality model CAMx (Comprehensive Air Quality Model with extensions). The modeled results from the standard and vapor wall loss corrected VBS schemes, as well as the traditional two-product approach were compared and evaluated by OA measurements from five Aerodyne aerosol chemical speciation monitor (ACSM)/aerosol mass spectrometer (AMS) stations in the winter of 2011. The vapor wall loss corrected VBS (VBS_WLS) generally shows the best performance for predicting OA among all OA schemes, and reduces the mean fractional bias from −72.9 % (with the standard VBS (VBS_BASE)) to −1.6 % for the winter OA. In Europe, the VBS_WLS produces the highest domain average OA in winter (2.3 µg m−3), which is 106.6 % and 26.2 % higher than the standard VBS and the reference scenario (VBS_noWLS, same parameterization as VBS_WLS, except with the default yields without vapor wall loss correction), respectively. Compared to VBS_noWLS, VBS_WLS leads to an increase in SOA by up to ~ 80 % in Romania. VBS_WLS also leads to a better agreement between the modeled SOA fraction in OA (fSOA) and the estimated measured values in the literature. The substantial influence of vapor wall loss correction on modeled OA in Europe highlights the importance of further improvements in the parameterizations based on laboratory studies with a wider range of chamber conditions and field observations with higher spatial and temporal coverage.
AN INTEGRATED BIM-GIS PLATFORM FOR REPRESENTING AND VISUALIZING 3D CADASTRAL DATA
Authors: Andrianesi D. E. , Dimopoulou E.
Published: September 2020

Abstract. The rapid urbanization over the last decades is leading to intensive land exploitation, and thus to the degradation of the city environment and the surrounding areas. This reality that applies at a global level, challenges new needs for sustainable growth and new ways to protect and ensure land property. It is of great importance, for the viable growth of every organized social structure, to protect land ownership and land-use in an appropriate way. Therefore arises the need for continuous and valid update of the complex Rights, Restrictions and Responsibilities (RRRs) within a developing 3D urban environment. For this environment, the interest focuses on ensuring land properties by improved methods of 3D information management, within modern land administration systems. The integration of Building Information Models (BIMs) and Geographic Information Systems (GIS) is expected to produce various advantages and play an important role in constructing 3D city models that successfully deal with every challenge in the urban landscape. GIS, in one hand, can manage and provide information about the existing environment, while on the other hand, BIMs focus on information regarding the design, construction and maintenance of a building /or complex structure inside that environment. This paper discusses the development of an integrated GIS and BIM 3D data platform enriched with 3D cadastral information This is illustrated with two use cases, a city block (No 464) in the area of Chalandri, Athens, and a four-floor building (at Kithaironos 21 street, in the same buildings’ block), used for applying BIM technology.
3D VIRTUAL MODELS FOR AN EARLY EDUCATION SERIOUS GAMING APPLICATION
Authors: Anastasiou D. , Avgeri T. , Iliodromitis A. , Pagounis V. , Tsakiri M.
Published: September 2020

Abstract. Visualization and conceptualisation of 3D objects are complex cognitive processes which are regarded essential from pre-school education to develop abilities linked to spatial and 3D thinking. The focus of this paper is to discuss the use of a virtual 3D environment as a pedagogical serious gaming platform that may help intensify learning processes. Recently, serious games are gaining popularity not only as games, but as promising educational tools too. This paper presents the creation of a simple ‘serious game’ where several tasks can be constructed that promote the 3D spatial thinking in pre-school education. Specifically, the creation of the virtual environment from a pre-school’s indoor and outdoor environment was performed using geodetic and terrestrial laser scanning techniques. To increase the geospatial sense of pre-school children within the virtual environment, an application was developed with simple educational tasks within the 3D environment. The templates, for each section of the gaming application, have been developed using HTML5 and CSS3, in order that they are interactive and accessible to all smart devices. The paper concludes with a discussion on the experience gained towards supporting spatial thinking for pre-school children.

Published: September 2020

Las Casas de encuentro en Chile son lugares donde las personas adultas mayores acuden durante el día con el objeto de realizar actividades en favor de un envejecimiento activo y en donde se llevan a cabo programas de actividades socioeducativas. Este trabajo ha estudiado la satisfacción de las personas adultas mayores con respecto a la formación que reciben. El diseño de la investigación es de carácter no experimental, descriptivo. El contexto del estudio ha sido la Casa de encuentro de Valparaíso con una participación de 205 personas adultas mayores. Los datos se han obtenido a través de un cuestionario de elaboración ad hoc con una escala de tipo Likert. Los resultados han revelado como hallazgos principales, el alto nivel de satisfacción de las personas adultas mayores, no estando este relacionado con los rasgos sociodemográficos de las personas adultas mayores como género, nivel de instrucción u ocupación previa, y sí con sus expectativas previas. La conclusión general es que estos programas son fuente de satisfacción en las personas adultas mayores, más allá de las competencias singulares que en cada caso pretendan promover en estos, debiendo ser una de las claves que orienten las políticas sociales para el envejecimiento activo que emergen como una necesidad cada vez mayor.

Unique Hungarian way of cross-cultural management Through an example of a multinational company in the oil and gas industry
Authors: Yousef Katul
Published: September 2020

Multiculturalism is a new phenomenon in Central-East European countries and has a different meaning than in Western Europe. There are many historical and cultural differences within Europe, as the Eastern countries cannot duplicate the West regarding cross-cultural management, and so they have to make their own tailor-made strategy. The countries that later joined the EU have their own unique position in business in accordance with the Muslim countries. One of the biggest multinational company in Central-East Europe is able to make an entrance into the overruled oil industry successfully. Content analyses of the company published documents, websites are summarized in this current paper in order to highlight the uniqueness of their CCM.

The freshwater clamCorbicula fluminea s.l. is an edible freshwater bivalve of economic value in Asia. The species has been particularly well studied in the invaded range. However, there is a lack of knowledge in its native range where it supports an increasing commercial harvest pressure. Among Asiatic countries, China accounts for 70% of known commercial harvest and aquaculture production. We aim to characterize here wildC. fluminea s.lpopulations exposed to commercial harvest pressure in Poyang Lake Basin. We found higher biomass, density and genetic diversity in lake populations compared to peripheral populations (i.e., lake tributaries). Given that lake habitats support more intense harvest pressure than peripheral habitats, we suggest that demographic and genetic differentiation among subpopulations may be influenced in some degree by different harvest pressure. In this regard, additional demographic and/or genetic changes related to increasing harvest pressure may place population at a higher risk of extirpation. Altogether, these results are especially relevant for maintaining populations at or above viable levels and must be considered in order to ensure the sustainability of the resource.

The study examined the effect of monetary policy on financial intermediation in Nigeria. Secondary data were collected from Central Bank of Nigeria statistical bulletin spanning from 1988 to 2018.The research work selected Nigeria as its sample and used the VECM to test the effect of the explanatory variables (Monetary Policy Rate, Cash Reserve Ratio, Loan to Deposit Ratio and Liquidity Ratio) on the dependent variable (Total Domestic Bank Credit).The findings from the study revealed that monetary policy has insignificant effect on intermediation in Nigeria. The granger causality test also shows a unidirectional causality between monetary policy and intermediation in Nigeria. The results suggest that lending interest rate is still high while deposit rate is low and this discourages savings and borrowing in the country. The study recommends among others that monetary policy should be reviewed in order to lower the cost of borrowing (lending rate) so as to encourage investors to borrow more. Commercial banks should try to increase its deposit rates which will help them to mobilize more deposits, as this will enhance their lending services. Financial infrastructure in the country should be improved upon as this will help banks in deposit mobilization especially the unbanked in the country.

Aim: To know the adaptation strategies undertaken by the respondents to deal with climate-smart agriculture.

Study Design: An expost facto research design was employed to analyse the level of adoption by the rice farmers.

Place and Duration of Study: The study was conducted during 2018-19 in Dharwad district of Karnataka state. From Dharwad district two villages namely Mummigatti from Dharwad taluk and Jodalli from Kalaghatagi taluk were selected.

Methodology: A total of 60 respondents were randomly selected and personally interviewed.

To elicit the required information from the respondents, a structured interview schedule was prepared. Through informal discussions and interviews, data was collected from the respondents. The collected data was analysed with the help of suitable statistical tools like frequency, percentage, mean, standard deviation and t-test.

Results: The results of the study revealed that majority of the respondents from Mummigatti (86.67%) and Jodalli (66.70%) had medium level of awareness regarding climate-smart agriculture. Majority of the respondents from Mummigatti (80.00%) and Jodalli (73.30%) were found in medium adaptation category. Equal percentage (20.00% each) of the respondents from both the villages belonged to the high adaptation category. The study also reveals that cent percent of the respondents from both the villages were faced constraints likelack of knowledge about adaptive practices, lack of awareness about climate change issues, non-availability of inputs in time, lack of financial resource, poor support of local and national authorities with the climate-related issue and higher cost of the agricultural inputs to cope with climatic variability.

Conclusion: From the study, it can be concluded that providing information and local support from the authorities will be of immense use in the proper adaption of site-specific climate-smart practices. The study also suggests that suitable policies and strategies should be taken to deal with non adaptation of climate-smart practices in the villages.

The effects of heat sources (oven, charcoal and stove) on roasted mackerel fish was investigated on proximate composition and sensory evaluation of roasted mackerel fish (Scromber scombrus). The fish sample was thawed, cut, eviscerated, washed with brine solution and roasted at a temperature of 75°C for 5 hours using oven, charcoal and stove as heat sources. Minor variations were obtained in crude protein, ash, fat, moisture and crude fibre contents amongst the roasted fish samples, while significant variation (p<0.05)was observed between the raw and roasted samples. The nutritive value of roasted fish improved as a result of the smoking process. In all the treated samples, the percentage of total protein, lipid and ash contents increased due to water loss during smoking. High value of ash was seen in experimental charcoal and stove heat sourced fish (15.86 & 14.56% respectively). Protein was retained better in oven sourced (49.17%) fish more than other sources used. The result of the sensory evaluation shows clearly that there was no significant difference in the level of acceptability of the three samples. The mean scores showed that all the characteristics of the products were moderately liked. Mean scores for overall acceptability indicates that the products were generally well accepted. Although the oven heated sample was more acceptable than other heat sources.

Aims: The present study was conducted to determine the antioxidant activity and chemical components of Ficus abutilifolia. Miq. (Moraceae).

Place and Duration of the Study: The study were performed at Department of chemistry, University of Ngaoundere, Cameroon, between July 2017 and September 2018.

Methodology: Phytochemical study was carried out on all extracts of stem barks. Besides, the total phenols contents (TPC) using the Folin-Ciocalteu and the antioxidant activities using DPPH and FRAP methods were also evaluated. The isolation of compounds from the EtOAc extract was done using column and thin layer chromatographic techniques on silica gel. The structures of isolated constituents were elucidated using mass spectrometry, 1D and 2D-NMR techniques.

Results: Phytochemical screening revealed that all the compounds tested were found to be present in the acetone extract; the hexane extract was the poorest in compounds. Acetone extract, DCM/MeOH (1:1) and MeOH extracts were found to be rich in phenols with TPC respectively (239. 849 ± 0.969), (232.676 ± 0.404) and (109.654 ± 0.724) mg EAG/100g EX. Except the n-hexane extract, all the others exhibit antioxidant activities, acetone extract being the most effective with an inhibitory concentration 50 (IC50) of (0.038 ± 0.002) mg/mL for the DPPH antiradical scavenging activity and (0,021 ± 0,002) mg/mL for FRAP. A new fatty acid named Pentacosyl henicosanoate (2) along with six known compounds Octatriacontane (1), β–sitosterol (3), a mixture of Lupeol acetate (4a), α-amyrin acetate (4b), β-amyrin acetate (4c) and Daucosterol (5) were isolated from the column chromatography of the ethyl acetate extract. Daucosterol (5) exhibited antiradical activity with an IC50 of (13.005 ± 0.005) mg/mL. Only Daucosterol (5) has exhibited antiradical activity with an IC50 of (13.005 ± 0.005) mg/mL among the isolated compounds.

Conclusion: This study provides scientific evidence and support for the traditional uses of F. abutilifolia stem barks in the treatment of diseases associated with oxidative stress.

The RecA protein plays a key role in bacterial homologous recombination (HR) and acts through assembly of long helical filaments around single‐stranded DNA in the presence of ATP. Large‐scale conformational changes induced by ATP hydrolysis result in transitions between stretched and compressed forms of the filament. Here, using a single‐molecule approach, we show that compressed RecA nucleoprotein filaments can exist in two distinct interconvertible states depending on the presence of ADP in the monomer–monomer interface. Binding of ADP promotes cooperative conformational transitions and directly affects mechanical properties of the filament. Our findings reveal that RecA nucleoprotein filaments are able to continuously cycle between three mechanically distinct states that might have important implications for RecA‐mediated processes of HR.

Although great progress has been made in coaxial extrusion printing toward generating microtubes for mimicking tubular tissues, these microtubes with insufficient mechanical properties and uncontrollable inherent swelling attribute severely hinder their utilization as load‐bearing tubular tissue. Herein, a high‐strength microtube is constructed by coaxial printing with a customized biohybird hydrogel ink consisting of nanoclay, H‐bonding monomer N‐acryloyl glycinamide, and gelatin methacryloyl. The physical interpenetration between nanoclay and polymer chains endows this ink with excellent printability and structural stability, thus facilitating the precise deposition of scalable microtubes with tunable small‐diameters and large‐scale lengths. After photocrosslinking, 3D‐printed biohybrid hydrogel microtube demonstrates marvelous mechanical properties with a tensile strength (≈22 MPa), a stretchability (≈500%), a Young's modulus (≈21 MPa), an anti‐fatigue performance (≈200 cycles), a burst pressure (≈2500 mmHg), and a suture retention strength (≈280 gf) in swelling equilibrium state, which are far superior to the previously printed microtubes and generally satisfy the requirements of tubular tissues. Additionally, this obtained microtube also displays favorable biological features that support adhesion, spreading, and endothelialization of human umbilical vein endothelial cells. This study successfully develops a biohybrid hydrogel ink to fabricate a scalable high‐strength microtube with enormous potential in regeneration of tube‐like tissues.

The light‐field (LF) imaging technique can obtain the light intensity and directional ray distribution information by utilizing a microlens array (MLA). Based on the recoded 3D information, full‐parallax or depth‐slice images can be reconstructed. Due to the limited ray sampling rate of the MLA, however, conventional LF imaging schemes are fatally susceptible to a trade‐off between the spatial and angular resolution. To mitigate this issue, a virtual‐moving metalens array (VMMA) based on a multifunctional dielectric metasurface is proposed, which can laterally shift the sampling position without physical movement, by simply tailoring the polarization of incident beam. Thanks to the polarization‐tailored VMMA, the LF imaging scheme is successfully realized to provide a fourfold enhanced spatial resolution without sacrificing the angular resolution.
