Unlocking the secrets of the microbiome: exploring the dynamic microbial interplay with humans through metabolomics and their manipulation for synthetic biology applications
Authors: Muhamadali Howbeer , Winder Catherine L. , Dunn Warwick B. , Goodacre Royston
Published: June 2023

Metabolomics is a powerful research discovery tool with the potential to measure hundreds to low thousands of metabolites. In this review, we discuss the application of GC–MS and LC–MS in discovery-based metabolomics research, we define metabolomics workflows and we highlight considerations that need to be addressed in order to generate robust and reproducible data. We stress that metabolomics is now routinely applied across the biological sciences to study microbiomes from relatively simple microbial systems to their complex interactions within consortia in the host and the environment and highlight this in a range of biological species and mammalian systems including humans. However, challenges do still exist that need to be overcome to maximise the potential for metabolomics to help us understanding biological systems. To demonstrate the potential of the approach we discuss the application of metabolomics in two broad research areas: (1) synthetic biology to increase the production of high-value fine chemicals and reduction in secondary by-products and (2) gut microbial interaction with the human host. While burgeoning in importance, the latter is still in its infancy and will benefit from the development of tools to detangle host–gut-microbial interactions and their impact on human health and diseases.
Cytoophidia and filaments: you must unlearn what you have learned
Authors: Guo Chen-Jun , Liu Ji-Long
Published: June 2023

The nucleotide CTP can be synthesized de novo from UTP via the metabolic enzyme CTP synthase (CTPS). As a textbook enzyme, CTPS has been extensively studied for seven decades. However, it came as a surprise when CTPS was found to form snake-shaped mesoscale cytoophidia in fruit fly cells. Since 2010, more and more studies have demonstrated that CTPS can form cytoophidia within the cells across all three domains of life. Oligomers of CTPS form filaments that are undetectable under light microscopy. This review summarizes our current understanding of cytoophidia and filaments, highlighting some basic features such as conservation, morphology and functions of the two levels of CTPS structures.
Asynchronous dynamic event‐triggered control for network systems with dual triggers
Authors: Guo Yuchao , Fang Xiaohan , Fan Yuan
Published: June 2023

This work proposes the framework of dual dynamic triggers to deal with the communication problem of remote control under the event‐triggered scheme for network control systems (NCSs). Compared with the existing NCSs, a local controller is set up at the plant site, which provides the local control input for the plant as a remote controller. The remote controller and the plant measurement have their individual dynamic triggers. Thus it is allowed that the local controller and the remote controller permit asynchronous communication, which is governed by different event conditions. It is proven that the proposed control strategy can drive the closed‐loop system asymptotically to equilibrium. Finally, a numerical example is presented to illustrate the effectiveness of the proposed method.
Mirror complementary transformer network for RGB‐thermal salient object detection
Authors: Jiang Xiurong , Hou Yifan , Tian Hui , Zhu Lin
Published: June 2023

Conventional RGB‐T salient object detection treats RGB and thermal modalities equally to locate the common salient regions. However, the authors observed that the rich colour and texture information of the RGB modality makes the objects more prominent compared to the background; and the thermal modality records the temperature difference of the scene, so the objects usually contain clear and continuous edge information. In this work, a novel mirror‐complementary Transformer network (MCNet) is proposed for RGB‐T SOD, which supervise the two modalities separately with a complementary set of saliency labels under a symmetrical structure. Moreover, the attention‐based feature interaction and serial multiscale dilated convolution (SDC)‐based feature fusion modules are introduced to make the two modalities complement and adjust each other flexibly. When one modality fails, the proposed model can still accurately segment the salient regions. To demonstrate the robustness of the proposed model under challenging scenes in real world, the authors build a novel RGB‐T SOD dataset VT723 based on a large public semantic segmentation RGB‐T dataset used in the autonomous driving domain. Extensive experiments on benchmark and VT723 datasets show that the proposed method outperforms state‐of‐the‐art approaches, including CNN‐based and Transformer‐based methods. The code and dataset can be found at https://github.com/jxr326/SwinMCNet.
Short‐term traffic flow prediction based on AST‐MTL‐CNN‐GRU
Authors: Yang Zijing , Wang Cheng
Published: June 2023

To address the current objective of short‐term traffic flow prediction on roads, this paper aims to predict not only the future traffic flow on roads, but also the average speed of future roads. Specifically, the authors propose a short‐term traffic flow prediction method based on the Convolutional Neural Network—Gate Recurrent Unit—Multi Task Learning‐time‐separated attention mechanism (AST‐MTL‐CNN‐GRU). Firstly, the authors add a time‐separated attention mechanism that can effectively generate attention matrices independently for different locations and times of the day. Secondly, the three main parameters of traffic flow, average speed and occupancy are combined in pairs as input data while the multi‐task learning is applied to predict the future traffic flow and average speed on the road. Finally, the CNNs are used to extract the spatial features and the GRUs are used to extract temporal features. Compared with the baseline models (diffusion CNNs (DCRNN), 1D‐CNN‐long short‐term memory (1DCNN‐LSTM), convolutional LSTM (ConvLSTM), graph WaveNet and ST‐ResNet), the authors’ proposed model has high performance in terms of accuracy, stability and robustness. A large number of ablation experiments are conducted based on five‐fold cross validation using the Quanzhou city dataset and the California dataset. The experimental results show that the combination of average speed and occupancy for input has higher prediction accuracy. In addition, the authors’ proposed model can outperform the other models being compared in terms of accuracy, stability and robustness even with noise added.
Dual‐band circular patch antenna working in TM41 and TM11 mode for on‐/off‐body communications
Authors: Gao Guo‐Ping , Dou Zhi‐Heng , Ma Ge , Wang Dan , Yu Zhuo‐Qi , Dong Jing‐Hang , Hu Bin
Published: June 2023

A capacitive coupling dual‐band circular patch antenna for on‐/off‐body communications is proposed for 3.5 GHz world interoperability for microwave access band and 5.8 GHz industrial scientific medical band. The antenna has a compact structure with a single substrate made of polydimethylsiloxane which is flexible and easy to wear. To realise off‐body mode, the antenna adopted bias feeding. The on‐body mode is achieved by symmetrically loading four shorting vias on the edge of the patch to stimulate TM41 mode, which tends to bring a high gain of the antenna. The measured operating bandwidths of the antenna for off‐body and on‐body modes are 120 MHz (3.45–3.57 GHz) and 360 MHz (5.54–5.90 GHz) respectively. The peak gains are 5.99 dBi for off‐body mode and 5.46 dBi for on‐body mode. Moreover, the antenna displays robust performances when it is bended or closed to human bodies. Meanwhile, low specific absorption rate values are proving that the antenna is safe to wear on human bodies.
A new symmetric modular eleven‐level inverter using single and double source unit for low voltage applications with reduced number of switches
Authors: Fakhri Naser , Laali Sara , Naderi Mohammad Salay , Rahimi Hossein , Farkoush Saeid Gholami
Published: June 2023

This study proposes a modular multilevel inverter for low‐voltage applications, including ac‐coupled renewables and energy storage systems. These inverters require many switches and gate drivers in their structures, which complicates the control system, reduces efficiency, and increases costs. This study introduces a new modular multilevel inverter that can produce five levels of positive voltage using only six power switches and five DC voltage sources. The basic unit is composed of a single‐ and double‐source (SDS) unit. SDS reduces the number of power electronic components, such as the insulated gate bipolar transistors, freewheeling diodes, gate driver circuits, dc voltage sources, and blocking voltage by switches. The proposed topology can boost the number of output voltage levels and decrease the number of switching devices and voltage stress using some combinations of basic submodules. The performance of the proposed 11‐level single‐phase inverter is compared with that of the conventional structures and recent symmetric topologies considering the number of switches, cost, and efficiency. The waveform quality and both the voltage and current harmonic characteristics were determined in accordance with IEEE 519–2014. Finally, an 11‐level prototype was constructed to validate the theoretical analysis, feasibility, and effectiveness of the proposed inverter.
Analysis, design, and implementation of switched Z‐source inverter with an extra control input
Authors: Zarei Golaleh , Babaei Ebrahim , Banae Sharifian Mohammad Bagher
Published: June 2023

The current study proposes a topology for switched Z‐source inverter. In the switching method used for this structure, unlike the conventional, the active network switches’ duty cycle is not equal to the shoot‐through duty cycle. So, in addition to the shoot‐through duty cycle, the duty cycle of impedance network switches is also involved in the boost factor. Besides, by extracting the small‐signal model, it is observed that the proposed topology has two control inputs on the dc‐side. The advantage of the additional control input is demonstrated by designing a closed‐loop control for the case where the inverter is used as an interface between the photovoltaics (PV) and the grid. In addition, the steady‐state analysis in different operating modes and the switching pattern are presented for the proposed topology. Comparing the number of elements and the boost factor of the proposed topology with several conventional topologies indicates that besides the control advantage, this topology has a higher voltage gain. Finally, simulation and experimental results are presented to verify theoretical discussions of the proposed inverter.
A possible common explanation for several cosmic microwave background (CMB) anomalies: A strong impact of nearby galaxies on observed large-scale CMB fluctuations
Authors: Hansen Frode K. , Boero Ezequiel F. , Luparello Heliana E. , Garcia Lambas Diego
Published: June 2023

Context. A new and hitherto unknown cosmic microwave background (CMB) foreground has recently been detected. A systematic decrease in CMB temperatures around nearby large spiral galaxies points to an unknown interaction with CMB photons in a sphere up to several projected megaparsecs around these galaxies.

Aims. We investigate to what extent this foreground may impact the CMB fluctuation map and create the so-called CMB anomalies.

Methods. Using the observed temperature decrements around the galaxies, and making some general assumptions about the unknown interaction, we propose a common radial temperature profile. By assigning this profile to nearby galaxies in the redshift range z = [0.004, 0.02], we created a foreground map model.

Results. We find a remarkable resemblance between this temperature model map, based on nearby galaxies, and the Planck CMB map. Compared to 1000 simulated maps, we find that none of them show such a strong correlation with the foreground map over both large and small angular scales. In particular, the quadrupole, octopole, and ℓ = 4 and ℓ = 5 modes correlate with the foreground map to a high significance. Furthermore, one of the most prominent temperature decrements in the foreground map coincides with the position of the CMB cold spot.

Conclusions. The largest scales of the CMB, and thereby the cosmological parameters, may change significantly after this foreground component is properly corrected. However, a reliable corrected CMB map can only be derived when suitable physical mechanisms are proposed and tested.

Pulsar timing arrays offer a probe of the low-frequency gravitational wave spectrum (1–100 nHz), which is intimately connected to a number of markers that can uniquely trace the formation and evolution of the Universe. We present the dataset and the results of the timing analysis from the second data release of the European Pulsar Timing Array (EPTA). The dataset contains high-precision pulsar timing data from 25 millisecond pulsars collected with the five largest radio telescopes in Europe, as well as the Large European Array for Pulsars. The dataset forms the foundation for the search for gravitational waves by the EPTA, presented in associated papers. We describe the dataset and present the results of the frequentist and Bayesian pulsar timing analysis for individual millisecond pulsars that have been observed over the last ~25 yr. We discuss the improvements to the individual pulsar parameter estimates, as well as new measurements of the physical properties of these pulsars and their companions. This data release extends the dataset from EPTA Data Release 1 up to the beginning of 2021, with individual pulsar datasets with timespans ranging from 14 to 25 yr. These lead to improved constraints on annual parallaxes, secular variation of the orbital period, and Shapiro delay for a number of sources. Based on these results, we derived astrophysical parameters that include distances, transverse velocities, binary pulsar masses, and annual orbital parallaxes.
Mindfulness and Negative Emotions: Chain Mediation Effect of Perceived Social Support and Interpersonal Sensitivity
Authors: Zhang JiaHui
Published: June 2023

Previous research has confirmed that mindfulness may decrease negative emotions in college students. However, there has been less focus on the mechanism of mindfulness’s effect on negative emotions. This study explores the relationship between mindfulness and negative emotions and examines the mediating role of perceived social support and interpersonal sensitivity among college students in China. A total of 386 college students (65.8% female, 34.2% male) completed measures of The Five Facet Mindfulness Questionnaire (FFMQ), The 21-item Depression Anxiety Stress Scale (DASS-21), The Multidimensional Scale of Perceived Social Support (MSPSS), and The Interpersonal Sensitivity Measure (IPSM). Using model 6 in SPSS PROCESS macro 3.3 software, we found： (1) mindfulness was negatively related to negative emotions; (2) interpersonal sensitivity mediated the relationship between mindfulness and negative emotions; (3) mindfulness was negatively related to negative emotions through the chain mediating of perceived social support and interpersonal sensitivity. Mindfulness, perceived social support, interpersonal sensitivity, and negative emotions in college students exerted significant associations with each other. Students can try mindfulness training to increase the perception of social support, reduce interpersonal sensitivity, and reduce negative emotions. The findings of this study may shed new light on the prevention and treatment of negative emotions among college students.
Exploring the Use of Austin’s Theory of Illocutionary Acts in Different Social Interactions
Authors: Guo Yijing
Published: June 2023

This paper reviews how Austin’s illocutionary act theory is used in face-to-face communication and online communication. In the aspect of face-to-face interaction, this paper places attention on the use of polite language and interaction in ESL (English as a second language) classrooms. In terms of online interaction, this paper explored interaction on Facebook and the use of memes, emoticons, emojis and stickers. After reviewing several research, this paper concluded that when talking face-to-face, the level of formality, gender, and cultural background affects people’s polite language. In ESL classrooms, the power, distance and rate of imposition affect teachers’ and students’ choice of language. However, the result of speech acts preference on Facebook is conflict. Previous research pointed out that memes can be categorized as communicative speech acts. Evidence shows that positive emoticons are preferred, which can improve friendships and vice versa. The review of literature contributes to further studies on the illocutionary act analysis of ESL classrooms in China and the communicative effectiveness of memes on the receivers.

Authors: Ma Yan , Yan Qiuzhen
Published: June 2023

At present, there are problems in the ideological and political education, such as insufficient awareness of all staff participation, difficulties in digging out ideological and political elements, educators with mixed qualities, single teaching mode of ideological and political courses, and lack of evaluation of ideological and political effectiveness. This paper takes the ideological and political course of “ Principles and Interface Technology of Microcontroller Unit” as an example, from the top-level design of the university, the design of professional talent training programs to specialized course design of ideological and political education. Using “Project + BOPPPS” mode, the comprehensive project “Water Level Monitoring and Display” is divided into three sub-projects. Each project has its specific knowledge, ability, accomplishment and educational goals, and the matching educational elements are selected to be organically integrated into the sub-projects. The trinity assessment method of “Knowledge + Skills + Attitude” is not only the evaluation of knowledge and ability,but also the evaluation of ideological and political effectiveness. The curriculum ideological and political implementation under this model has certain achievements and has certain reference value.

Background: Firefighters are at high risk for developing posttraumatic stress disorder (PTSD), with attention bias being a contributing factor. Attention Control Training (ACT) is a cognitive behavioral intervention for PTSD treatment and prevention, but its effectiveness for firefighters is unverified. Methods: A randomized controlled trial involving the Kunming Training Brigade of the Fire Rescue Bureau assessed the impact of four weeks of ACT exercises on PTSD symptoms, attention bias, and attention-bias variability. Results: 180 individuals were randomized into two groups. Within groups, there was a significant decrease in PTSD symptoms from pre- to post-intervention for both the intervention and control groups. Additionally, a comparison of post-intervention PTSD symptoms between the intervention and control groups showed a statistically significant difference, with the intervention group showing lower levels of PTSD symptoms than the control group (U = 4688, p = 0.048, r = -0.148). The post-intervention analysis also revealed a statistically significant difference in ABV between the intervention and control groups, with the intervention group showing a greater reduction in ABV than the control group (U = 4766, p = 0.041, r = -0.153). Conclusions: The present study provides evidence that ACT can be an effective intervention for preventing PTSD among firefighters. The study highlights the importance of addressing mental health concerns among firefighters and contributes to the development of effective interventions for the prevention of PTSD among high-risk populations. Further research is needed to determine the long-term effectiveness of the intervention and to examine its generalizability to other populations.

Objective Our objective was to determine whether objectively measured sleep-disordered breathing (SDB) during pregnancy is associated with an increased risk of adverse neonatal outcomes in a cohort of nulliparous individuals.

Study Design Secondary analysis of the nuMom2b sleep disordered breathing substudy was performed. Individuals underwent in-home sleep studies for SDB assessment in early (6–15 weeks' gestation) and mid-pregnancy (22–31 weeks' gestation). SDB was defined as an apnea-hypopnea index ≥5 events/h at either time point. The primary outcome was a composite outcome of respiratory distress syndrome, transient tachypnea of the newborn, or receipt of respiratory support, treated hyperbilirubinemia or hypoglycemia, large-for-gestational age, seizures treated with medications or confirmed by electroencephalography, confirmed sepsis, or neonatal death. Individuals were categorized into (1) early pregnancy SDB (6–15 weeks' gestation), (2) new onset mid-pregnancy SDB (22–31 weeks' gestation), and (3) no SDB. Log-binomial regression was used to calculate adjusted risk ratios (RR) and 95% confidence intervals (CIs) representing the association.

Results Among 2,106 participants, 3% (n = 75) had early pregnancy SDB and 5.7% (n = 119) developed new-onset mid-pregnancy SDB. The incidence of the primary outcome was higher in the offspring of individuals with early (29.3%) and new onset mid-pregnancy SDB (30.3%) compared with individuals with no SDB (17.8%). After adjustment for maternal age, chronic hypertension, pregestational diabetes, and body mass index, new onset mid-pregnancy SDB conferred increased risk (RR = 1.43, 95% CI: 1.05, 1.94), where there was no longer statistically significant association between early pregnancy SDB and the primary outcome.

Conclusion New onset, mid-pregnancy SDB is independently associated with neonatal morbidity.

Published: June 2023

The general and efficient palladium-loading ceramic catalytic membrane reactor has been first reported to apply in the Mizoroki–Heck reaction. The as-fabricated catalytic membrane Pd-KH792-CM has shown high activity and selectivity in the flow-through Mizoroki–Heck reactions. The consistently high activity of the catalytic membrane in the five cycles has also proved its good stability and recyclability. Synthesis of drug molecules has further demonstrated that the catalytic membrane protocol is a powerful and comprehensive alternative to the traditional Mizoroki–Heck cross-coupling.

Published: June 2023

Background Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) using lumen-apposing metal stents (LAMSs) appears to be effective and safe in gastric outlet obstruction (GOO); however, the EUS-GE procedure is not standardized, with the use of assisted or direct methods still debated. The aim of this study was to compare the outcomes of EUS-GE techniques focusing on an assisted with orointestinal drain wireless endoscopic simplified technique (WEST) and the nonassisted direct technique over a guidewire (DTOG).

Method This was a multicenter European retrospective study involving four tertiary centers. Consecutive patients who underwent EUS-GE for GOO between August 2017 and May 2022 were included. The primary aim was to compare the technical success and adverse event (AE) rates of the different EUS-GE techniques. Clinical success was also analyzed.

Results 71 patients (mean [SD] age 66.2 10 years; 42.3 % men; 80.3 % malignant etiology) were included. Technical success was higher in the WEST group (95.1 % vs. 73.3 %; estimate of relative risk from odds ratio (eRR) 3.2, 95 %CI 0.94–10.9; P = 0.01). The rate of AEs was lower in the WEST group (14.6 % vs. 46.7 %; eRR 2.3, 95 %CI 1.2–4.5; P = 0.007). Clinical success was comparable between the two groups at 1 month (97.5 % vs. 89.3 %). The median follow-up was 5 months (range 1–57).

Conclusion The WEST resulted in a higher technical success rate with fewer AEs, with clinical success comparable with the DTOG. Therefore, the WEST (with an orointestinal drain) should be preferred when performing EUS-GE.

Published: June 2023

Background Chronic low back pain (CLBP) is a global health problem, and gabapentin and pregabalin are often used in the treatment of patients without associated radiculopathy or neuropathy. Therefore, determining their efficacy and safety is of enormous value.

Objective To examine the efficacy and safety of using gabapentin and pregabalin for CLBP without radiculopathy or neuropathy.

Methods We performed a search on the CENTRAL, MEDLINE, EMBASE, LILACS, and Web of Science data bases for clinical trials, cohorts, and case-control studies that evaluated patients with CLBP without radiculopathy or neuropathy for at least eight weeks. The data were extracted and inserted into a previously-prepared Microsoft Excel spreadsheet; the outcomes were evaluated using the Cochrane RoB 2 tool, and the quality of evidence, using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

Results Of the 2,230 articles identified, only 5 were included, totaling 242 participants. In them, pregabalin was slightly less efficacious than amitriptyline, the combination of tramadol/acetaminophen, and celecoxib, and pregabalin added to celecoxib showed no benefit when compared to celecoxib alone (very low evidence for all). On the other hand, although one study with gabapentin did not support its use in a general sample of patients with low back pain, another found a reduction in the pain scale and improved mobility (moderate evidence). No serious adverse events were observed in any of the studies.

Conclusion Quality information to support the use of pregabalin or gabapentin in the treatment of CLBP without radiculopathy or neuropathy is lacking, although results may suggest gabapentin as a viable option. More data is needed to fill this current gap in knowledge.
