Lensless phase-only holographic Maxwellian display based on double-phase decomposition for optical see-through near-eye display applications
Authors: Luo Yuhang , Wan Wenqiang , Zhou Yanhong , Su Yanfeng 
Published: July 2024

Abstract

The holographic Maxwellian display holds significant potential as a technique for augmented reality presentations due to its capability to address the vergence-accommodation conflict in see-through near-eye displays. However, conventional lensless holographic Maxwellian displays predominantly rely on amplitude-type holograms, facing challenges such as low diffraction efficiency and interference from conjugate images. To overcome these limitations, we propose a lensless phase-only holographic Maxwellian display tailored for optical see-through near-eye applications. In our approach, a complex amplitude distribution, calculated using the angular spectrum diffraction method, was encoded into a phase hologram via the double-phase decomposition algorithm. This phase hologram can effectively converge the virtual target image onto the viewer’s pupil by multiplying the phase hologram with a convergent spherical wave at the hologram plane, enabling viewers to consistently perceive all-in-focus images at the pupil location. Additionally, we introduced a digital grating to mitigate the interference caused by other-order diffraction images. Finally, experimental results demonstrated that our proposed near-eye display system can accurately generate see-through virtual images without the vergence-accommodation conflict issue by loading the designed phase hologram onto a phase-type spatial light modulator. Furthermore, the eyebox expansion has been realized by multiplying the phase hologram with multiple convergent spherical waves.

Abstract

Remediation of lead (Pb)-contaminated soils is increasingly important because production of food crops in these soils is associated with human health risk. The present study investigated use of natural zeolite to remediate Pb-contaminated soil by quantifying changes in soil properties, soil nutrients and distribution of Pb in spinach plant parts. Natural zeolite was added to pots containing four different soil media that were artificially amended with Pb in a greenhouse. Zeolite was mixed with the media at four rates plus a zero control, and for three of the Zeolite rates a second application was made to the soil surface in the pot 30 days later for a total of eight zeolite treatments. The 32 treatments were replicated four times. Pb immobilization by zeolite was dose dependent, with greater immobilization at higher zeolite rates. Heterogeneous soil humus components exerted both mobilizing and stabilizing effects, so the medium nutrition was most effective for phytostabilization. So,split applications of zeolite were more effective than once, because the lag-phase time of split zeolite treatment applications was longer than for one application, to the same total dosage. This method might be an efficient way to remediate the lead-polluted soils with zeolite application twice.

Published: July 2024

Abstract

The administrative public interest litigation system (APILS) is an important guarantee for environmental public interest protection and an important institutional innovation of external supervision, which has great significance for low-carbon development. This study takes the listed companies from 2000 to 2021 in China as the research samples, and examines the impact of APILS on corporate carbon emissions (CCE). The results show that: (1) The APILS can significantly promote the reduction of CCE. (2) This research conclusion exhibits multidimensional heterogeneity, which varies depending on the industry type, market competition level, city size, and resource attributes. (3) The mechanism test shows that the APILS can promote CCE reduction through three mechanisms: green innovation, public environmental claims and environmental administrative regulation. (4) Further expansive analyses finds that social trust can strengthen the inhibitory effect of the APILS on CCE. The conclusion of this study provides empirical evidence for exploring the role of external public welfare system supervision in promoting CCE reduction.

Abstract

A novel refractive index sensor based on surface plasmon resonance (SPR) of an excentric-core photonic crystal optical fiber (PCF) is proposed, whose cladding consists of air holes of two sizes and double gold nanowires are coated on its outer surface. The air hole diameter and spacing, gold-nanowire diameter are optimized respectively to obtain the optimal sensing performance by using the finite element method (FEM). The results indicate that the proposed ex-centric core PCF-SPR sensor with the gold nanowire diameter of 0.9 µm can detect refractive index of 1.34 ~ 1.39 in the wavelength range of 600 ~ 1500 nm with the maximum wavelength sensitivity of 51200 nm/RIU, amplitude sensitivity of -1248.5 RIU− 1, minimum resolution of 1.95×10− 6 RIU and optimal FOM of 179.33 RIU− 1. The PCF-SPR has potential applications including temperature measurement, organic chemical detection, medical detection, biomolecular detection and so on.

Abstract

Agroforestry changes the traditional land use mechanism and has the advantage of intensive eco-economic compound. The photosynthetic characteristics of planting areas are the driving and restricting factors for the accumulation of plant material conversion. To investigate the response of the yield of apple-watermelon intercropping and the yield of fruit trees and crops to photosynthetic characteristics, the growth indexes, photosynthetic characteristics, yield, and benefits of single apple (CK1), single watermelon (CK2) and compound cropping modes were studied respectively. The results showed that the final growth indexes of intercropping apples were higher than those of the single model. However, due to the shading effect of high fruit trees on low crops, the normal growth of watermelon was inhibited, and the growth level of intercropping watermelon was lower than that of single mode. The Pn of apples and watermelons in different planting patterns showed a bimodal trend, and reached the peak value between 10:00–12:00 and 14:00–16:00. The daily variation curve of PAR showed an unimodal trend, and the peak value of apples and watermelons under the two planting patterns appeared between 12:00–14:00 and 10:00–12:00, respectively. Compound planting benefited apples from higher Pn and PAR, and vice versa for watermelon. The diurnal variation of Gs and Tr of intercropping and single species of apple and watermelon first increased and then decreased in an inverted V pattern, the diurnal variation trend of Ci showed a V pattern. The Gs, Tr, and Ci of apple in compound mode were higher than that of watermelon in single mode. The yield of apples increased by 46.34% in the combined apple-watermelon planting mode, and the yield of the combined planting mode was significantly higher than that of the single planting mode due to the advantage of the unit price of apples. In the apple-watermelon compound planting model, the total income was 5.19×105 yuan /hm2, the income of the single apple model was 2.46×105 yuan /hm2, and the income of the single watermelon model was 1.85×105 yuan /hm2. The land utilization rate was 232.20% and the income utilization efficiency was 210.98%.
Formation and pinch-off of leading vortex ring in starting jets with uniform background crossflow
Authors: Zhao Ruijia , Zhang Guoqing , Zhu Jianwei , Yu S.C.M. 
Published: July 2024

Abstract

The formation and pinch-off of leading vortex ring in the starting jets with uniform background crossflow have been investigated numerically for Rv from 3 to 12and ∞,where Rv is the ratio of the jet velocity Uj to the velocity of background crossflow Uc. Rv = ∞ represents the case without any background crossflow. The background crossflow disrupts the symmetry in the formation process of leading vortex ring, causing it to move laterally and the circulation strength on either side of it to be unequal. The difference in the circulation strength can be normalized based on slug model. The lateral movement introduced by crossflow is found to be inversely proportional to Rv,but directly proportional to Uc at aconstant Uj. A kinematic model based on the lateral movement of leading vortex ring is established to characterize the pinch-off process in the starting jet with background crossflow. The occurrence of pinch-off at Rv ≥ 12 remains consistent with that without background crossflow, i.e., the formation number F remains constant with Rv. As for smaller Rv (less than 12), F increases linearly with Rv,i.e., F ∼ C2Rv,where C2 is a constant.
TGFB2-AS1 binding to MED1 promotes doxorubicin-induced cardiomyocyte apoptosis via BMP7 pathway

Published: July 2024

Abstract

Doxorubicin-induced cardiotoxicity (DIC) is similar to dilated cardiomyopathy (DCM) in morphological and functional defects, eventually progressing to heart failure. Recently, intensive investigation showed that specific expression profiles of lncRNA have been closely related to cardiovascular disease, but many gaps remain, including the emerging roles of lncRNA in DIC. We identified TGFB2-AS1 as a highly conserved regulator of DCM by reanalyzing publicly available RNA sequencing datasets from GEO and producing conservation scores of lncRNAs using PHAST software. TGFB2-AS1 expression is dramatically increased in murine and cell models, and TGFB2-AS1 has a pro-apoptotic effect in vitro. Moreover, TGFB2-AS1 mediated apoptosis via the BMP7 pathway by activating the Smad1/5/9 phosphorylation to upregulate the target gene expression Id2. Recombinant human bone morphogenetic protein (rhBMP-7) aggravates doxorubicin-induced cardiomyocyte apoptosis, and knockdown of BMP7 significantly reverses the pro-apoptotic effect of TGFB2-AS1 overexpression in vitro. Mechanistically, we found that TGFB2-AS1 combines with transcriptional co-activator MED1, promoting H3K27 acetylation modification level in the promoter of the BMP7 gene and then facilitating BMP7 transcription. Collectively, this study illuminates that TGFB2-AS1 is an evolutionarily conserved long noncoding RNA with a previously unappreciated role in promoting the apoptotic phenotype of DIC and sheds light on the more effective clinical application of doxorubicin.

Authors: Jing Wendan , Jia Qinyao , Wu Xiufei , He Jinsong , Jian Changchun 
Published: July 2024

Abstract

Objectives
Previous studies attempted to relieve drug-related asthenia by analyzing the blood metabolites. Metabolism as a potential mechanism of asthenia may be a clue for developing effective prevention and treatment methods. This study aimed to explore the causal relationship of metabolites or metabolic pathways to asthenia.
Methods
We adopted single nucleotide polymorphisms (SNPs) as genetic instruments to evaluate the levels of 486 circulating metabolites. These SNPs were obtained from large-scale genome-wide association studies originating from Europe. We investigated the causal impact of genetically predicted circulating metabolites on asthenia by a two-sample Mendelian randomization (MR) analysis. The sensitivity analysis estimated the reliability of the results, containing MR-Egger, weighted median, and weighted mode. Every one standard deviation (SD) elevation in exposure was revealed as odds ratios (OR) with 95% confidence intervals (CIs).
Results
After screening 486 circulating metabolites in this MR, we identified a causal relationship between 17 metabolites and asthenia. Among which bilirubin Z (IVW OR = 0.956; 95% CI: 0.934–0.979; P < 0.01), myristoleate (OR = 0.903; 95% CI: 0.822–0.993; P = 0.035), N-acetylalanine (OR = 0.961; 95% CI: 0.938–0.985; P = 0.001), threonate (OR = 0.922; 95% CI: 0.857–0.991; P = 0.028), 1-methylxanthine (OR = 0.917; 95% CI: 0.859–0.978; P = 0.009) were causally associated with reduced risk of asthenia. Arachidonate (OR = 1.305; 95% CI: 1.165–1.462; P < 0.01), kynurenine (OR = 1.204; 95% CI: 1.067–1.359; P = 0.003), lysine (OR = 1.335; 95% CI: 1.116–1.597; P = 0.002), octadecanedioate (OR = 1.121; 95% CI: 1.041–1.208; P = 0.003), oleoylcarnitine (OR = 1.161; 95% CI: 1.015–1.329; P = 0.030), palmitoleate (OR = 1.231; 95% CI: 1.023–1.480; P = 0.028), stearoylcarnitine (OR = 1.194; 95% CI: 1.042–1.369; P = 0.011), thymol sulfate (OR = 1.035; 95% CI: 1.011–1.059; P = 0.004), valine (OR = 2.042; 95% CI: 1.400-2.979; P < 0.01), 3-dehydrocarnitine (OR = 1.182; 95% CI: 1.076-1.300; P < 0.01), 4-methyl-2-oxopentanoate (OR = 1.235; 95% CI: 1.009–1.511; P = 0.040), 4-vinylphenol sulfate (OR = 1.098; 95% CI: 1.046–1.153; P < 0.01) were related to a higher risk of asthenia. This result is not affected by heterogeneity and horizontal pleiotropy. Metabolic pathway analysis suggested three pathways that probably correlated to asthenia, they were “Glycine, serine and threonine metabolism (P = 0.00174)”, “Glycerophospholipid metabolism (P = 0.0304)”, “Phenylalanine, tyrosine and tryptophan biosynthesis (P = 0.0309)”.
Conclusions
This MR study discovered a causal effect of blood metabolites on the asthenia risk. These metabolites and metabolic pathways can be applied in asthenia prevention and treatment strategies.

Abstract

The local environment modulation of iron sites in Fe-N4 single atom catalysts (SACs) plays a crucial role in the efficient peroxymonosulfate (PMS) activation. Many reported modulation strategies involve the partial replacement of N in the first coordination shell of Fe-N4 sites with foreign elements to facilitate the PMS activation via disrupting the structural symmetry, suffering from undesired catalytic stability. Herein, we demonstrate that Fe-N4-C6O2 sites, which are prepared by substituting C in the second coordination shell of Fe-N4 sites with O, can activate PMS more efficiently and stably by providing an enhanced localized electric field without destroying their symmetric coordination structure in the first coordination shell, and thus achieve an unprecedented catalytic durability of at least 240 h. The O doping in the second coordination shell strengthened the Fe-N bond by reducing the electron density of Fe center, and weakened the amplitude of Fe-N bond from 0.875 ~ 3.175 Å to 0.925 ~ 2.975 Å during the PMS activation, therefore effectively prevented the demetallation of Fe-N4 sites. Meanwhile, this O doping also lowered the energy of Fe = O σ* orbitals by weakening the coordination field to promote the electrophilic σ-attack of high-valent iron-oxo (FeIV=O) towards electron-rich contaminants, thus enhancing the bisphenol A degradation rate from 1.08 × 103 M− 1 s− 1 to 4.6 × 104 M− 1 s− 1 by a factor of 41.6. This work sheds light on the importance of second coordination shell doping on the ultrastability of Fe-N4 SACs, and provides a novel strategy to design metal SACs by balancing a trade-off between exceptional activity and long-term stability.

Abstract

The present research was conducted aiming at the effectiveness of compassion-therapy training on suicidal thoughts of adolescent girls. The present research methodology was an experiment with a pre-test, post-test design with a control group. The statistical population of the research included 33 female adolescent students from three second secondary schools in Khomein County in the academic year of 2022–2023, who had a history of self-harm and were referred to Education Counseling Center. Out of this number, 20 students were selected by simple random sampling method and randomly divided into two 10-individual groups. The experimental group and the control group were determined randomly. The suicidal ideation scale of Erich et al. (1991) was used to gather the data. Gilbert's (2021) self-compassion training intervention was implemented in 8 training sessions for 90 minutes during a month (twice a week). One-way analysis of covariance test was used to analyze the data. The findings indicated that compassion-therapy training has been influential on adolescent girls' suicidal thoughts and this training has explained 70% of the variance of the suicidal thoughts. Based on the findings of this research, it can be concluded that the self-compassion-focused treatment is an effective strategy to help reduce the suicidal thoughts of adolescent girls.

Published: July 2024

Abstract

Many economic gold deposits on Earth are associated with volcanic arcs. However, little is known about the factors that control the gold endowment of the parental arc magmas. Here, we present new high-precision geochemical data from submarine glasses recovered from the length of the Kermadec arc. We show that the combined systematics of Au, Ag and Cu helps to decipher sources and processes responsible for Au enrichment in arc magmas. These data show that hydrous melting in the Kermadec subarc mantle occurs predominantely at high temperatures in the presence of sulfide liquid. The highest Au (>8 ppb at MgO> 5 wt.%), Au/Cu (up to 6*10-6) and mantle-like Ag/Cu values correspond to high-temperature second-stage melting. Elevated temperatures in a hydrous subarc mantle enables enhanced and multiple-stage melting of highly depleted mantle and thus is a prerequisite of Au enrichment in parental arc magmas.

Bowel obstruction is one of the emergency cases that require prompt intervention. It remains a challenging issue to surgeons due to many possible differential diagnoses [1]. This retrospective study was intended to highlight the common causes of intestinal obstruction. A total of 172 patients who were diagnosed with intestinal obstruction and were operated in the department of surgery in Al-mouassat hospital in Damascus from February 2022 to January 2024 were taken for this study and they were compared in terms of sex, age group, diagnostic tools, presenting symptoms, and treatment. In addition, we compared our study with another two studies regarding the same topic.
Orexinergic modulation of chronic jet lag-induced deficits in mouse cognitive flexibility

Published: July 2024

Abstract

Cognitive flexibility and working memory are important executive functions mediated by the prefrontal cortex and can be impaired by circadian rhythm disturbances such as chronic jet lag (CJL) or shift work. In the present study, we used mice to investigate whether (1) simulated CJL impairs cognitive flexibility, (2) the orexin system is involved in such impairment, and (3) nasal administration of orexin A is able to reverse CJL-induced deficits in cognitive flexibility and working memory. Mice were exposed to either standard light-dark conditions or simulated CJL consisting of series of advance time shifts. Experiment (1) investigated the effects of a mild CJL protocol on cognitive flexibility using the attentional set shifting task. Experiment (2) used a stronger CJL protocol and examined CJL effects on the orexin system utilizing c-Fos and orexin immunohistochemistry. Experiment (3) tested whether nasal orexin application can rescue CJL-induced deficits in cognitive flexibility and working memory, the latter by measuring spontaneous alternation in the Y-maze. The present data show that CJL (1) impairs cognitive flexibility and (2) reduces activity of orexin neurons in the lateral hypothalamus. (3) Nasal administration of orexin A rescued CJL-induced deficits in working memory and cognitive flexibility. These findings suggest that executive functions impairments by circadian rhythm disturbances such as CJL are caused by dysregulation of orexinergic input to the prefrontal cortex. Compensation of decreased orexinergic input by nasal administration of orexin A could be a potential therapy for CJL- or shift work-induced human deficits in executive functions.
