Prevalence and Correlation of Anxiety, Insomnia and Somatic Symptoms in a Chinese Population During the COVID-19 Epidemic

Background Anxiety has been a common mental state during the epidemic of Coronavirus Disease 2019 (COVID-19) and is usually closely related to somatization. However, no study on somatization in anxiety and its relationship with insomnia has been conducted. Therefore, this study aimed to identify the prevalence of anxiety, somatization and insomnia and explore the relationships between different psychological states in the general population during the COVID-19 outbreak. Methods A total of 1,172 respondents were recruited from 125 cities in mainland China by an online questionnaire survey. All subjects were evaluated with the 7-item Generalized Anxiety Disorder (GAD-7) scale, the somatization subscale of the Symptom Checklist 90-Revised (SCL-90-R), and the 7-item Insomnia Severity Index (ISI). Results The percentages of anxiety, somatization, and insomnia were 33.02%, 7.59%, and 24.66%, respectively. The prevalence of somatization was 19.38% in participants with anxiety. Compared to the anxiety without somatization group, the anxiety with somatization group had a significantly higher percentage of patients with a history of physical disease and insomnia, as well as higher GAD-7 scores and SCL-90 somatization subscores (all p < 0.001). The SCL-90 somatization subscores were positively correlated with age, history of physical disease, GAD-7 scores, and ISI scores (all p < 0.001). Furthermore, multivariate logistic regression showed that GAD-7 score, ISI score, and age were risk factors for somatization in the anxious population. Conclusions Somatic and psychological symptoms were common in the general population during the COVID-19 outbreak. Somatic symptoms, anxiety, and insomnia are closely related, and improving anxiety and sleep quality may help relieve somatic symptoms.
Evaluation of Several Feature Detectors/Extractors on Underwater Images towards vSLAM

Modern visual SLAM (vSLAM) algorithms take advantage of computer vision developments in image processing and in interest point detectors to create maps and trajectories from camera images. Different feature detectors and extractors have been evaluated for this purpose in air and ground environments, but not extensively for underwater scenarios. In this paper (I) we characterize underwater images where light and suspended particles alter considerably the images captured, (II) evaluate the performance of common interest points detectors and descriptors in a variety of underwater scenes and conditions towards vSLAM in terms of the number of features matched in subsequent video frames, the precision of the descriptors and the processing time. This research justifies the usage of feature detectors in vSLAM for underwater scenarios and present its challenges and limitations.
Intelligent agents: theory and practice

Abstract The concept of an agent has become important in both artificial intelligence (AT) and mainstream computer science. Our aim in this paper is to point the reader at what we perceive to be the most important theoretical and practical issues associated with the design and construction of intelligent agents. For convenience, we divide these issues into three areas (though as the reader will see, the divisions are at times somewhat arbitrary). Agent theory is concerned with the question of what an agent is, and the use of mathematical formalisms for representing and reasoning about the properties of agents. Agent architectures can be thought of as software engineering models of agents; researchers in this area are primarily concerned with the problem of designing software or hardware systems that will satisfy the properties specified by agent theorists. Finally, agent languages are software systems for programming and experimenting with agents; these languages may embody principles proposed by theorists. The paper is not intended to serve as a tutorial introduction to all the issues mentioned; we hope instead simply to identify the most important issues, and point to work that elaborates on them. The article includes a short review of current and potential applications of agent technology.
Opportunistic Network Behavior in a Swarm: Passing Messages to Destination

This paper evaluates and compares two routing algorithms for message passing in opportunistic peer-to-peer networks in the swarm network simulator Swarm-Sim. The two considered algorithms, Epidemic Routing and PRoPHET Routing, are compared in terms of delivery rates, efficiency and overhead, while presenting different mobility models. By this, we combine a variation of mobility models and a set of communication protocols, measuring their impact on the swarm behavior. Message delivery rates for Epidemic routing are considerably and consistently better. However, PRoPHET generates less overhead than Epidemic Routing independent of mobility models and scenarios. The measured overhead of Epidemic exceeded that of PRoPHET by about 100%. Memory requirements for keeping delivery probabilities - used by PRoPHET to circumvent flooding - might be a limitation as they must be kept locally per peer, this detail offers aspects for further research in the future. Finally, this paper demonstrates Swarm-Sim to be a viable alternative to simulate routing protocols in opportunistic peer to peer networks without requiring great insight into the simulator’s architecture and thus establishing itself as an easy to use simulator. It achieves simplicity without yielding any of flexibility of application.
Multi-Connectivity Management for Mobile Ultra-Reliable Low-Latency Communications

—Recent mission critical wireless applications, such as emergency stop and safety application protocols (e.g., PROFIsafe), require ultra-reliable low-latency communications (URLLC) technologies to ensure error-free message transmission with hard real-time requirements. Multi-connectivity (MC) has emerged as a promising approach to enable URLLC in 5G. Applying MC in mobile communications poses multiple technical challenges, such as advanced handover (HO) schemes handling multiple links in parallel, highly dynamic link optimization, avoiding massive link drops due to fading and shadowing, and optimizing radio resource allocation/consumption. To address these challenges we propose an MC management scheme based on maximum ratio combining (MRC) for mobile communications in industrial scenarios. We compare the performance with existing HO schemes for Rayleigh fading channel conditions using extensive simulations. Compared to existing approaches, the results show improvements in achievable signal to noise ratio, link utilization, data rate, and availability.
Phospholipid profiles and hepatocellular carcinoma risk and prognosis in cirrhotic patients

Background Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Phospholipids are now well-recognised players in tumour progression. Their metabolic tissue alterations can be associated with plasmatic modifications. The aim of this study was to evaluate the potential of the plasma phospholipid profile as a risk and prognostic biomarker in HCC. Methods Ninety cirrhotic patients with (cases) or without HCC (controls) were studied after matching for inclusion centre, age, gender, virus infection, cirrhosis duration and Child-Pugh grade. High-performance liquid chromatography coupled with tandem-mass spectrometry was used to quantify the main species of seven categories of phospholipids in plasma. Results Elevated concentrations of phosphatidylcholine (PC) 16:0/16:1 (p=0.0180), PC 16:0/16:0 (p=0.0327), PC 16:0/18:1 (p=0.0264) and sphingomyelin (SM) 18:2/24:1 (p=0.0379) and low concentrations of lysophosphatidylcholine 20:4 (0.0093) and plasmalogen-phosphatidylethanolamine (pPE) 16:0/20:4 (p=0.0463), pPE 18:0/20:4 (p=0.0077), pPE 18:0/20:5 (p=0.0163), pPE 18:0/20:3 (p=0.0463) discriminated HCC patients from cirrhotic controls. Two ceramide species were associated with increased HCC risk of death while lysophospholipids, a polyunsaturated phosphatidylinositol, some PC and SM species were associated with low risk of death in HCC patients in 1 and/or 3 years. Conclusion This study identified phospholipid profiles related to HCC risk in liver cirrhotic patients and showed for the first time the potential of some phospholipids in predicting HCC patient mortality.
Session Subtyping and Multiparty Compatibility Using Circular Sequents.

We present a structural proof theory for multi-party sessions, exploiting the expressive power of non-commutative logic which can capture explicitly the message sequence order in sessions. The approach in this work uses a more ﬂexible form of subtyping than standard, for example, allowing a single thread to be substituted by multiple parallel threads which fulﬁl the role of the single thread. The resulting subtype system has the advantage that it can be used to capture compatibility in the multiparty setting (addressing limitations of pairwise duality). We establish standard results: that the type system is algorithmic, that multiparty compatible processes which are race free are also deadlock free, and that subtyping is sound with respect to the substitution principle. Interestingly, each of these results can be established using cut elimination. We remark that global types are optional in this approach to typing sessions; indeed we show that this theory can be presented independently of the concept of global session types, or even named participants.
Model-Free Reinforcement Learning for Stochastic Parity Games

This paper investigates the use of model-free reinforcement learning to compute the optimal value in two-player stochastic games with parity objectives. In this setting, two decision makers, player Min and player Max, compete on a ﬁnite game arena – a stochastic game graph with unknown but ﬁxed probability distributions – to minimize and maximize, respectively, the probability of satisfying a parity objective. We give a reduction from stochastic parity games to a family of stochastic reachability games with a parameter ε , such that the value of a stochastic parity game equals the limit of the values of the corresponding simple stochastic games as the parameter ε tends to 0. Since this reduction does not require the knowledge of the probabilistic transition structure of the underlying game arena, model-free reinforcement learning algorithms, such as minimax Q-learning, can be used to approximate the value and mutual best-response strategies for both players in the underlying stochastic parity game. We also present a streamlined reduction from 1 12 -player parity games to reachability games that avoids recourse to nondeterminism. Finally, we report on the experimental evaluations of both reductions.
Multi-User Digital Beamforming Based on Path Angle Information for mm-Wave MIMO Systems

—In millimeter-wave wireless communications, beam-forming, also known as beamsteering is a promising technique that enables the base station, with a large number of antennas, to mitigate the tremendous path loss. This paper aims to assess the performance of two digital beamformers, namely, conjugate beamforming (CB) and digital beamsteering (DBS) in a millimeter-wave environment based on geometric aspects, such as the antenna array topology or the location of the user in the cell. The realistic channel model NYUSIM, from New York University, reproduces a mono-and multi-path urban scenario. We show that DBS, with only line-of-sight path angle information at the transmitter, outperforms CB, with full channel state information at the transmitter, in mono-path environment. However, in multi-path scenario, DBS is not able to exploit the diversity of non-line-of-sight paths and CB outperforms DBS.
Inhibition and nematocidal effect of plant extracts on Meloidogyne incognita

Nematicidal effect of 53 plant extracts on the second juvenile of Meloidogyne incognita (J2) were determined , the results showed that 20 plant extracts had higher nematicidal activities against J2, in which 11 extracts could kill more than 50% of J2 in 24h, such as Tagetes erecta, Albizzia spp, Melia toosendan, Sinapis alba, etc. The inhibition effect of 24 plant extracts on eggs activities were also determined, the results showed that 23 plant extracts had inhibition on eggs hatch, such as Radix stemonae , Nerium indicum, Albizzia spp, Sinapis alba, etc, inhibition effect of Radix stemonae extract on eggs hatch was the highest, inhibition rate of eggs hatch was 96. 57% i 16 plant extracts had effect of killing eggs, such as Albizzia spp, Ipomoea triloba, Asarum sieboldii, Cnidium monnier, etc, in which Albizzia spp extract was the highest, egg mortility rate could reach 84- 41%.
Is In-hospital Meta-information Useful for Abstractive Discharge Summary Generation?

During the patient's hospitalization, the physician must record daily observations of the patient and summarize them into a brief document called “discharge summary” when the patient is discharged. Automated generation of discharge summary can greatly relieve the physicians' burden, and has been addressed recently in the research community. Most previous studies of discharge summary generation using the sequence-to-sequence architecture focus on only inpatient notes for input. However, electric health records (EHR) also have rich structured metadata (e.g., hospital, physician, disease, length of stay, etc.) that might be useful. This paper investigates the effectiveness of medical meta-information for summarization tasks. We obtain four types of meta-information from the EHR systems and encode each meta-information into a sequence-to-sequence model. Using Japanese EHRs, meta-information encoded models increased ROUGE-1 by up to 4.45 points and BERTScore by 3.77 points over the vanilla Longformer. Also, we found that the encoded meta-information improves the precisions of its related terms in the outputs. Our results showed the benefit of the use of medical meta-information.
Bioethanol from sawdust using cellulase hydrolysis of Aspergillus ochraceus and fermentation by Saccharomyces cerevisiae.

Biofuel refers to liquid or gaseous fuel mainly for the transport sector that are predominantly produced from various biomass resources such as wheat, sugar beet, corn, paddy straw, wood, municipal wastes and forestry by-products etc. Generally, biofuel offer many benefits that include sustainability, reduction of greenhouse gas emissions, engine compression ratio and also reduce the environmental pollution (Reijnders, 2006). A variety of liquid fuels such as bioethanol, methanol and biodiesel can be used as an alternative fuel for transport, besides other alternatives of gaseous fuels such as Liquid Natural Gas (LNG), Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG) and hydrogen (Semin et al., 2009).
Diagnosis and management of an inappropriate sinus tachycardia in adolescence based upon a Holter ECG: A retrospective analysis of 479 patients

Inappropriate sinus tachycardia (IST) is a common disease of the autonomic nervous system in children and adults. Diagnosis and treatment of IST in adolescents is not well defined. In this retrospective study, we tested our hypothesis regarding autonomic dysfunction in childhood by analyzing 24-h heart rate variability (HRV) in 479 children, with a mean age of 13.7 ± 2.1 years, who were referred to the outpatient clinic in the Pediatrics Department within the last 15 years. Seventy-four adolescents with a mean 24-h heart rate ≥ 95 bpm (our cut-off for an IST based upon 66 healthy controls) were deemed to have IST. We found the risk of IST to be high in adolescents with attention deficit disorder (OR = 3.5,p<0.001), pre-hypertension (OR = 2.5, p = 0.043) and hypertension (OR = 2.1,p = 0.02); insignificantly enhanced in children with short stature (OR = 1.9,p = 0.19), surgically-treated congenital heart disease (OR = 1.4,p = 0.51) and obesity without hypertension (OR = 1.4;p = 0.25); and negligible in adolescents with anorexia nervosa (OR = 0.3, p = 0.26) and constitutional thinness (OR = 0.9,p = 0.89). IST was associated with a significant decrease in global HRV and elevated blood pressures, indicating an enhanced cardiovascular risk. Methylphenidate did not increase 24-h heart rates, whereas omega-3 fatty acid supplementation significantly decreased elevated heart rates and increased HRV in adolescents with IST. In this retrospective analysis, 15.4% of adolescents suffered from IST with a 24-h heart rate ≥ 95 bpm, predominately due to attention deficit disorder and hypertension.
A steady-state model of microbial acclimation to substrate limitation

Microbes acclimate to changes in substrate availability by altering the number of transporters on the cell surface, however there is some disagreement on just how. We revisit the physics of substrate uptake and consider the steady-state scenario whereby cells have acclimated to maximize fitness. Flux balance analysis of a stoichiometric model of Escherichia coli was used in conjunction with quantitative proteomics data and molecular modeling of membrane transporters to reconcile these opposing views. An emergent feature of the proposed model is a critical substrate concentration S*, which delineates two rate limits. At concentrations above S*, transporter abundance can be regulated to maintain uptake rates as demanded by maximal growth rates, whereas below S*, uptake rates are strictly diffusion limited. In certain scenarios, the proposed model can take on a qualitatively different shape from the familiar hyperbolic kinetics curves, instead resembling the long-forgotten Blackman kinetics.
Prognostic and Clinicopathological Significance of FADD Upregulation in Head and Neck Squamous Cell Carcinoma: A Systematic Review and Meta-Analysis

Fas-associated death domain (FADD) upregulation, i.e., gene amplification, protein phosphorylation and/or overexpression, has shown promising prognostic implications in head and neck squamous cell carcinoma (HNSCC). This systematic review and meta-analysis aims to evaluate the clinicopathological and prognostic significance of FADD upregulation in HNSCC. We searched studies published before February 2020 through PubMed, Embase, Web of Science, Scopus and Google Scholar. We evaluated the quality of the studies included using the QUIPS tool. The impact of FADD upregulation on survival and clinicopathological variables was meta-analysed. We explored heterogeneity and their sources, conducted sensitivity analyses and investigated small-study effects. Thirteen studies (1,923 patients) met inclusion criteria. FADD immunohistochemical overexpression was statistically associated with worse overall survival (hazard ratio [HR] = 1.52, 95% confidence intervals [CI] = 1.28–1.81, p < 0.001), disease-specific survival (HR = 2.52, 95% CI = 1.61–3.96, p < 0.001), disease-free survival (HR = 1.67, 95% CI=1.29–2.15, p < 0.001), higher clinical stage (odds ratio [OR] = 1.72, 95% CI = 1.17–2.51, p = 0.005) and a large magnitude of effect with N+ status (OR = 2.36, 95% CI = 1.85–3.00, p < 0.001). FADD phosphorylation in ser-194 demonstrated no prognostic value, while no conclusive results can be drawn for FADD gene amplification. In conclusion, our findings indicate that immunohistochemical assessment of FADD overexpression could be incorporated into the prognostic evaluation of HNSCC.
Use of plant epidermis for determination of macrophytes consumed by Distichodus rostratus Günther, 1864 (Pisces : Distichodontidae), of Taabo artificial lake (Basin of Bandama, Côte d’Ivoire).

Fish constitutes one of the principal sources of proteins in the majority of African countries such as Cote d'Ivoire. However, its production is subjected to various constraints primarily of nutritional nature. This study was initiated to determine the plant base diet of local fish Distichodus rostratus for its valorisation in aquaculture. The micro-histological method was applied to the stomach contents and aquatic plants inventoried in Ahondo (Taabo Lake) in order to determine floristic composition of consumed food by D. rostratus. After treatment in sodium hypochlorite, the epidermis of plants were observed using an optic microscope and compared. The results revealed that the plant species consumed by this Fish species were, essentially, Ipomoea aquatica, Echinochloa pyramidalis, Polygonum senegalense and Pycreus macrostachys . Keywords : Distichodus rostratus, diet, epidermis, Aquatic plants, Macrophytis.
Suicide ideation versus suicide attempt: Examining overlapping and differential determinants in a large cohort of patients with depression and/or anxiety

Objective: Individuals with a depressive and/or anxiety disorder are known to have an elevated risk of suicide. However, these diagnoses alone are insufficient at differentiating patients with suicide ideation that attempt suicide from those that do not. Few studies examined such differences in an ideation-to-action framework. Using this framework, extensive multivariate testing was performed to examine differences between suicidal patients with and without a suicide attempt. Method: Data were from 1576 respondents with a depressive and/or anxiety disorder, participating in the Netherlands Study of Depression and Anxiety. Logistic regression analyses were used to analyze associations between sociodemographic, clinical, personality, and psychosocial risk factors and suicide ideation and attempt. Results: Patients with suicide ideation could be uniquely distinguished from non-suicidal patients by more years of education, presence of a depressive disorder (vs anxiety disorder) and higher introversion. Patients with suicide ideation and a past suicide attempt could be uniquely distinguished from non-suicidal patients by a younger age of onset, a lifetime alcohol use disorder, more external locus of control and lower levels of social support. Within the group of patients with suicide ideation, patients with a suicide attempt were more likely to have childhood trauma and lower education, and be of non-Western descent than patients with suicide ideation and no past attempt. Conclusion: This study found that although various clinical, personality and psychosocial characteristics distinguish patients with suicide ideation from non-suicidal patients, many of these often-cited factors do not distinguish patients with a suicide attempt from those who only think about suicide. However, childhood trauma, lower education and non-Western descent could aid in detecting suicide attempt risk among patients with suicide ideation.
Spirituality, Quality of Life, and End of Life Among Indigenous Peoples: A Scoping Review

Introduction: While spirituality and quality of life (QOL) are essential components of end-of-life (EOL) care, limited studies have examined these constructs for indigenous peoples. Therefore, the purpose of this article was to examine the state of the science regarding spirituality and QOL at EOL for indigenous people, particularly Native Americans. Method: The Arksey and O’Malley (2005) framework guided this scoping review, which examined 30 articles that included qualitative and quantitative studies, commentary papers, and reviews. Results: The findings identified five spiritual dimensions: the life and death journey, a belief in spirits, tribally grounded traditions, dominant cultural religion influences, and a family focus. QOL indicators included survivorship, optimization of holistic health, communication, and access to appropriate resources. Death rituals were important EOL elements. Discussion: Given the importance of spirituality to QOL for indigenous people, clinicians must be knowledgeable and responsive to indigenous spiritual needs to promote QOL at EOL.
