Numerical simulation research on fragments formation of cylindrical cased charge based on SPH method

In order to obtain the fracture and fragmentation of a cased charge under blast loading, the JWL equation of state of HMX-based PBX was fitted based on a cylinder test firstly, then the smooth particle hydrodynamics (SPH) method was used to perform a simulation of cased charge under interior blast loading, in the meantime, an blast test of cased charge was conducted. The results show that the parameters of JWL equation of state and the simulation method were reasonably. The simulated fragments velocities and calculated results from empirical formula agreed well with each other, the maximum error did not exceed 9.5%. Under the direct loading of the detonation wave, the fragments velocities increased to more than 1000m/s immediately within 5us, and then the fragments were continuously accelerated by detonation products and shock wave until the fragments reached the maximum velocities in the later 250us. Eventually, the shape of expansion contour of the casing tended to be ellipsoid. The method and results can provide references for the power design of the fragment warhead, as well as the protection design against the fragments.

Calculation and optimization of lethal power of controlled fragmentation warheads with diamond notch grid

The lethal power is the critical design index of the explosive warhead, mainly related to the number and mass of fragments formed by the warhead case. For the controlled fragmentation warhead case containing notches, the notch depth and spacing are the main factors affecting the fragment formation. This paper analyzes the influence of the notch number and depth on the network of fracture trajectories. It establishes a calculation model for the mass and number of fragments of warheads with various groove parameters. The lethal radius is obtained from the calculated fragment data and compared with the results of the experimental data and numerical simulation. The paper uses the genetic algorithm to obtain the optimal solution under various design variables, taking the groove depth and the number of circumferential grooves as the design variables and the lethal radius as the optimization objective. The optimized result is higher than without optimization.

A comprehensive quality evaluation strategy of Mailuoning oral liquid based on fingerprint, qualitative and quantitative analyses

In order to obtain comprehensive quality evaluation of one traditional Chinese patent medicine of Mailuoning oral liquid (MLN), one smart strategy combined by fingerprint, qualitative and quantitative analyses were carried out in this study. Firstly, the fingerprints of MLN were established by HPLC-UV and HPLC-ELSD, and explained the similarity of twenty-seven batches of MLN by similarity analysis (SA). Secondly, qualitative analysis was performed by high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (HPLC-QTOF-MS/MS). A total of 60 compounds were identified or tentatively identified based on chemical standards and fragmentation information. Finally, the quantitative method based on UPLC combined with triple quadrupole mass spectrometry (UPLC-QqQ-MS/MS) was developed for the simultaneous determination of 40 target compounds. The results showed that MLN samples of different productive year were clearly discriminated and eight compounds (5-hydroxymethyl-2-furaldehyde, neochlorogenic acid, loganic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, isoacteoside, angoroside C) were selected as differential markers for MLN. In a word, this strategy including fingerprint, identification of chemical composition and multiple-component quantification could be well applied to modern quality evaluation of MLN, which could be valuable for the further quality control of more other traditional Chinese patent medicines.

Keeping up with evidence-based recommendations – a qualitative interview study with general practitioners in Germany on information-seeking behaviour in cardiovascular care

BackgroundDue to the nature of their work, general practitioners (GPs) need to be up to date with evidence in various medical domains. While much synthesised research evidence is easily accessible nowadays, in practice, the time to search for and review this evidence proposes a challenge. In German primary care, the knowledge infrastructure is rather fragmented, leaving GPs with relatively few primary care specific resources of information and many resources from other medical fields. This study aimed to explore GPs information-seeking behaviour regarding evidence-based recommendations in cardiovascular care in Germany.MethodsTo explore views of GPs a qualitative research design was chosen. Data was collected through semi-structured interviews. In total, 27 telephone interviews with GPs were conducted between June and November 2021.Verbatim transcript interviews were then analysed using thematic analysis, deriving at themes inductively.ResultsTwo broad strategies of information-seeking behaviour in GP could be distinguished: (a) generic information-seeking behaviour and (b) casuistic information-seeking. The first referring to strategies GPs apply to keep up with medical developments such as new medication and the second referring to purposeful information exchange regarding individual patients, such as referral letters. The second strategy was also used to keep up with medical developments in general.ConclusionIn a fragmented information landscape, GPs used information exchange on individual patients to remain informed about medical developments in general. Initiatives to implement recommended practices need to take this into account, either by using these sources of influence or by making GPs aware of possible bias and risks. The findings also emphasize the importance of systematic evidence-based sources of information for GPs.Trail registrationWe registered the study prospectively on 07/11/2019 at the German Clinical Trials Register (DRKS, www.drks.de) under ID no. DRKS00019219.

The infl uence of the nature of isocyanates and their concentration on the formation of imide fragments in the polymer matrix, on the physical-mechanical and temperature-deformation properties of foams is shown. The glass transition temperatures of the obtained materials are determined.

Research on the Relieving Effect of ASMR Chewing Sounds on Anxiety in Food Video

Short food videos combine elements such as lens, ingredients and soundtrack, so that people can be immersive when watching short videos. The creation and watching of short food videos meet people's spiritual needs of learning, entertainment and social interaction. Nowadays, great changes have taken place in the social environment, and people are faced with thousands of fragmented information every day. Due to the infectious and creative characteristics of short food videos, they can quickly attract the attention of the public in a fragmented information environment. Autonomous sensor meridian response (ASMR) mukbang, as a form of mukbang, has also continuously expanded its fan circle and become a popular form of mukbang. The uniqueness of ASMR phenomenon is mainly reflected in two aspects: in the sense, individuals will have a specific tingling sensation; Emotionally, it is often accompanied by extremely pleasant and relaxing experiences. This article expounds the development characteristics of short food videos in the new media environment, and studies the relieving effect of ASMR chewing sound on anxiety in food videos.

The Research on the Happiness Brought by Chinese Short Video Software Douyin to Chinese College Students

Douyin is now a popular short video app for Chinese college students. Most Chinese college students watch Douyin for entertainment. So how Douyin brings happiness to college students is worth studying. A questionnaire was made for college students to fill out to help with the study. Through data analysis of the questionnaire results, the conclusions are showed that first Chinese college students are attracted by entertaining videos on Douyin, and they like livestream function of Douyin most, which also brings them happiness. Douyin had become a form of entertainment among college students during the quarantine as well. Furthermore, fragmented video information transmission mode on Douyin makes some students think the joy they get is continuous, while others think it is transient. In addition, most students agree that Douyin is a vulgar way of entertainment, mainly due to the uneven quality of the videos on this platform. Overall, this study presented that Douyin does bring happiness to Chines college students. However, this kind of video content that brings students happiness is tacky to some extent and has no substantive meaning.

The Information Fragmentation in the Internet Era

It is the internet that brings the information fragmentation era, further influencing peoples life as well as society. As human beings are stepping into the information fragmentation era, both the input and the output of the information changes significantly, and these changes further bring many influences to the masses and society. In this process, the medium has played an essential role. This study explores the reasons and influences of the information fragmentation era from the perspective of the internet. This study analyzes the features of the internet and the input and output of fragmented information. The study reveals that the internet changes the quality of the information, peoples habits of the input, and the output of information. The quality of the information becomes hard to distinguish, and the information is not as deep as it used to be. People are more passionate about reading the information in fragments, and many media also create information in fragments, which is a considerable change led by the internet

Association of Fragmented Readmissions and Electronic Information Sharing With Discharge Destination Among Older Adults

When an older adult is hospitalized, where they are discharged is of utmost importance. Fragmented readmissions, defined as readmissions to a different hospital than a patient was previously discharged from, may increase the risk of a nonhome discharge for older adults. However, this risk may be mitigated via electronic information exchange between the admission and readmission hospitals. To determine the association of fragmented hospital readmissions and electronic information sharing with discharge destination among Medicare beneficiaries. This cohort study retrospectively examined data from Medicare beneficiaries hospitalized for acute myocardial infarction, congestive heart failure, chronic obstructive pulmonary disease, syncope, urinary tract infection, dehydration, or behavioral issues in 2018 and their 30-day readmission for any reason. The data analysis was completed between November 1, 2021, and October 31, 2022. Same hospital vs fragmented readmissions and presence of the same health information exchange (HIE) at the admission and readmission hospitals vs no information shared between the admission and readmission hospitals. The main outcome was discharge destination following the readmission, including home, home with home health, skilled nursing facility (SNF), hospice, leaving against medical advice, or dying. Outcomes were examined for beneficiaries with and without Alzheimer disease using logistic regressions. The cohort included 275 189 admission-readmission pairs, representing 268 768 unique patients (mean [SD] age, 78.9 [9.0] years; 54.1% female and 45.9% male; 12.2% Black, 82.1% White, and 5.7% other race and ethnicity). Of the 31.6% fragmented readmissions in the cohort, 14.3% occurred at hospitals that shared an HIE with the admission hospital. Beneficiaries with same hospital/nonfragmented readmissions tended to be older (mean [SD] age, 78.9 [9.0] vs 77.9 [8.8] for fragmented with same HIE and 78.3 [8.7] years for fragmented without HIE; P < .001). Fragmented readmissions were associated with 10% higher odds of discharge to an SNF (adjusted odds ratio [AOR], 1.10; 95% CI, 1.07-1.12) and 22% lower odds of discharge home with home health (AOR, 0.78; 95% CI, 0.76-0.80) compared with same hospital/nonfragmented readmissions. When the admission and readmission hospital shared an HIE, beneficiaries had 9% to 15% higher odds of discharge home with home health (patients without Alzheimer disease: AOR, 1.09 [95% CI, 1.04-1.16]; patients with Alzheimer disease: AOR, 1.15 [95% CI, 1.01-1.32]) compared with fragmented readmissions where information sharing was not available. In this cohort study of Medicare beneficiaries with 30-day readmissions, whether a readmission is fragmented was associated with discharge destination. Among fragmented readmissions, shared HIE across admission and readmission hospitals was associated with higher odds of discharge home with home health. Efforts to study the utility of HIE for care coordination for older adults should be pursued.

Disrupting mechanical homeostasis promotes matrix metalloproteinase-13 mediated processing of neuron glial antigen 2 in mandibular condylar cartilage.

Post-traumatic osteoarthritis in the temporomandibular joint (TMJ OA) is associated dysfunctional cellmatrix mediated signalling resulting from changes in the pericellular microenvironment after injury. Matrix metalloproteinase (MMP)-13 is a critical enzyme in biomineralisation and the progression of OA that can both degrade the extracellular matrix and modify extracellular receptors. This study focused on MMP-13 mediated changes in a transmembrane proteoglycan, Neuron Glial antigen 2 (NG2/CSPG4). NG2/CSPG4 is a receptor for type VI collagen and a known substrate for MMP-13. In healthy articular layer chondrocytes, NG2/CSPG4 is membrane bound but becomes internalised during TMJ OA. The objective of this study was to determine if MMP-13 contributed to the cleavage and internalisation of NG2/CSPG4 during mechanical loading and OA progression. Using preclinical and clinical samples, it was shown that MMP-13 was present in a spatiotemporally consistent pattern with NG2/CSPG4 internalisation during TMJ OA. In vitro, it was illustrated that inhibiting MMP-13 prevented retention of the NG2/CSPG4 ectodomain in the extracellular matrix. Inhibiting MMP-13 promoted the accumulation of membrane-associated NG2/CSPG4 but did not affect the formation of mechanical-loading dependent variant specific fragments of the ectodomain. MMP- 13 mediated cleavage of NG2/CSPG4 is necessary to initiate clathrin-mediated internalisation of the NG2/ CSPG4 intracellular domain following mechanical loading. This mechanically sensitive MMP-13-NG2/CSPG4 axis affected the expression of key mineralisation and OA genes including bone morphogenetic protein 2, and parathyroid hormone-related protein. Together, these findings implicated MMP-13 mediated cleavage of NG2/CSPG4 in the mechanical homeostasis of mandibular condylar cartilage during the progression of degenerative arthropathies such as OA.

Cuticle of Hermetia Illucens Black Lion Pupa as A Biosorbent for Probiotics

Using the method of scanning electron microscopy, a comparative study of the particle surface morphology and the elemental composition of the cuticle of Hermetia illucens pupa before and after the application of the culture liquid (CL) of the probiotic strain Lactobacillus acidophilus B 2707 was carried out. At the same time, under the influence of CL, destruction of relatively large particles of the powder of the chitin-protein complex of the cuticle (average particle diameter D 845.3 ± 109.1 μm) and the formation of small fragments (average D 63.4 ± 13.9 μm), including nanoparticles (average D 54 ± 18 nm). A biofilm of lactobacilli enriched with calcium, magnesium and phosphorus was obtained on a sorbent consisting of microparticles of the cuticle of insect pupae and including nanoparticles, which provided the probiotic preparation with high biological efficiency.

Temperature-Dependent Growth and Spore Germination of Fungi Causing Grapevine Trunk Diseases: Quantitative Analysis of Literature Data.

Grapevine trunk diseases (GTDs) are serious threats in all viticultural areas of the world, and their management is always complex and usually inadequate. Fragmented and inconsistent information on the epidemiology and environmental requirements of the causal fungi is among the reasons for poor disease control. Therefore, we conducted a quantitative analysis of literature data to determine the effects of temperature on mycelial growth and the effects of temperature and moisture duration on spore germination. Using the collected information, we then developed mathematical equations describing the response of mycelial growth to temperature, and the response of spore germination to temperature and moisture for the different species and disease syndromes. We considered 27 articles (selected from a total of 207 articles found through a systematic literature search) and 116 cases; these involved 43 fungal species belonging to three disease syndromes. The mycelial growth of the fungi causing Botryosphaeria dieback (BD) and the esca complex (EC) responded similarly to temperature, and preferred higher temperatures than those causing Eutypa dieback (ED) (with optimal temperature of 25.3, 26.5, and 23.3°C, respectively). At any temperature, the minimal duration of the moist period required for 50% spore germination was shorter for BD (3.0 h) than for EC (17.2 h) or ED (15.5 h). Mathematical equations were developed accounting for temperature-moisture relationships of GTD fungi, which showed concordance correlation coefficients ≥0.888; such equations should be useful for reducing the risk of infection.

Resonance Electron Capture by 5-Methyluridine and 3'-Deoxythymidine Molecules

Negative ion mass spectrometry is used to study processes of resonant electron attachment by 5‑methyluridine and 3'-deoxythymidine nucleoside molecules in the electron 0–14 eV range of energies. It is established that they are similar to those in nucleosides studied earlier (uridine, deoxyuridine, thymidine). The main channels of the fragmentation of molecular ions are revealed, and the absolute cross sections for the formation of fragment ions are determined. It is found that the intensity of the breaking the glycosidic bond in 3'-deoxythymidine in the region of low energies is two and a half orders of magnitude below the one in stavudine, testifying to the prospect of replacing the antiretroviral drug stavudine with 3'-deoxythymidine if radiation therapy is required for oncological diseases contracted as complications of HIV.

Fate and Impacts of Microplastics in the Environment: Hydrosphere, Pedosphere, and Atmosphere

Plastic litter is on the rise where plastic waste ends up in undesignated areas such as the coastal shorelines, where the plastic is exposed to environmental conditions. As a result, the degradation and decomposition of plastics occur, leading to the formation of smaller fragments of plastics, termed microplastics. Microplastics have recently been considered as an emerging class of contaminants due to their ecotoxicological impact on the aquatic environment as well as soil matrix. Microplastics are of a size less than 5 mm and are produced from either a primary source (such as plastic pellets, and beads in makeup products) or a secondary source (such as the wear and tear of normal-use plastics and washing of clothes and textiles). Microplastic pollution is spread across the hydrosphere, pedosphere, and atmosphere, and these environmental zones are being studied for microplastic accumulation individually. However, there exists a source–sink dynamic between these environmental compartments. This study reviews the available literature on microplastic research and discusses the current state of research on the fate and transport of microplastic in the hydrosphere, pedosphere, and atmosphere, explores the ecotoxicological impact of microplastics on aquatic and soil communities, and provides prospective future research directions and plastic waste management strategies to control microplastic pollution. While the fate of microplastics in the hydrosphere is well-documented and researched, studies on understanding the transport mechanism of microplastics in the pedosphere and atmosphere remain poorly understood.

Triglyceride mixtures: Cold-bursting and double emulsion formation

It was shown recently that a solid-to-solid phase transitions (α-to-β, gel-to-crystal), typical for many lipid substances, can lead to formation of nanoporous network inside lipid micro-particles dispersed in aqueous surfactant solutions (Cholakova et al. ACS Nano2020, 14, 8594). These nanopores are spontaneously infused by the aqueous phase when appropriate combination of water-soluble and oil-soluble surfactants is applied. As a result, the initial lipid micro-particles can spontaneously burst into much smaller nanoparticles, just by cooling and heating of the initial dispersion. Under certain conditions, the infused aqueous phase is entrapped in the moment of lipid particle melting and double emulsion of type water-in-oil-in-water (W/O/W) is formed. The current study aims to clarify how the composition of the lipid micro-drops and surfactants affect the observed phenomena. Selected mixtures of monoacid triglycerides are studied systematically. The results show that the bursting efficiency usually decreases when the complexity of the lipid mixture increases, due to the expanded temperature interval for lipid melting. Nevertheless, complete particle bursting and lipid nanoparticles with diameters down to 20 nm are formed even for the most complex lipid compositions under appropriate conditions. The key mechanisms leading to efficient fragmentation and double emulsion formation are clarified, and the main governing factors are explored. On this basis, we reveal that the system behavior can be switched between complete particle bursting and W/O/W emulsion formation by: (1) Change in the cooling and heating rates without any changes in the chemical composition, (2) Change in the concentration of oil-soluble surfactant, and/or (3) Change in the phase in which the oil-soluble surfactant is introduced initially. Thus, we have formulated guiding rules to control the formation of lipid nanoparticles and W/O/W emulsions with triglyceride mixtures promising multiple potential applications.

Tat-malate dehydrogenase fusion protein protects neurons from oxidative and ischemic damage by reduction of reactive oxygen species and modulation of glutathione redox system

Malate dehydrogenase (MDH) plays an important role in the conversion of malate to oxaloacetate during the tricarboxylic acid cycle. In this study, we examined the role of cytoplasmic MDH (MDH1) in hydrogen peroxide (H2O2)-induced oxidative stress in HT22 cells and ischemia-induced neuronal damage in the gerbil hippocampus. The Tat-MDH1 fusion protein was constructed to enable the delivery of MDH1 into the intracellular space and penetration of the blood–brain barrier. Tat-MDH1, but not MDH1 control protein, showed significant cellular delivery in HT22 cells in a concentration- and time-dependent manner and gradual intracellular degradation in HT22 cells. Treatment with 4 μM Tat-MDH1 significantly ameliorated 200 μM H2O2-induced cell death, DNA fragmentation, and reactive oxygen species formation in HT22 cells. Transient increases in MDH1 immunoreactivity were detected in the hippocampal CA1 region 6–12 h after ischemia, but MDH1 activity significantly decreased 2 days after ischemia. Supplementation of Tat-MDH1 immediately after ischemia alleviated ischemia-induced hyperlocomotion and neuronal damage 1 and 4 days after ischemia. In addition, treatment with Tat-MDH1 significantly ameliorated the increases in hydroperoxides, lipid peroxidation, and reactive oxygen species 2 days after ischemia. Tat-MDH1 treatment maintained the redox status of the glutathione system in the hippocampus 2 days after ischemia. These results suggest that Tat-MDH1 exerts neuroprotective effects by reducing oxidative stress and maintaining glutathione redox system in the hippocampus.

Abstract 1387: Novel thienopyrimidine-hydrazinyl analog, TPH104m inhibits mitochondrial respiration and induces caspase-independent cell death in triple-negative breast cancer cells

Abstract A triple negative breast cancer (TNBC) is an aggressive and difficult-to-treat breast cancer subtype. Neoadjuvant chemotherapy using apoptosis-inducing taxanes and/or anthracyclines has been shown to produce early therapeutic responses. Unfortunately, drug resistance often results from mutations in apoptotic pathways, which can lead to metastasis and poor prognosis. There are emerging studies suggesting that TNBC tumors display altered mitochondrial dynamics and have overexpressed dynamin related protein 1 (Drp1), which drives mitochondrial fission. Drp1 deregulation also influences metabolic changes and mitochondrial energetics, which support TNBC tumor growth. Therefore, bypassing apoptosis signaling cascade, suppressing Drp1 and reversing aberrant mitochondrial dynamics may be an effective therapy for TNBC. We report here for the first time the identification of novel thienopyrimidine-hydrazinyl analog of parent TPH104, namely, TPH104m, which inhibits Drp1 phosphorylation and induces a non-apoptotic TNBC cell death. TPH104m significantly inhibited TNBC proliferation at nanomolar concentrations, and was more selective for TNBC than normal human mammary epithelial cells. TPH104m induced a unique type of non-apoptotic cell death, where cells swelled without shrinkage, nuclear fragmentation or apoptotic bleb formation typical of apoptosis. Moreover, TPH104m did not induce the cleavage of initator (caspase-8, -9) and executioner caspases (caspase-3, -7), and zVAD.fmk, a pan-caspase inhibitor, did not rescue TNBC cell death when incubated with TPH104m. Furthermore, TPH104m did not significantly increase reactive oxygen species (ROS) production in BT-20 cells compared to Paclitaxel treated cells. Although mitochondrial membrane potential (MMP) was significantly reduced, cytochrome C release was not increased, but instead decreased, explaining why MMP loss did not lead to apoptosis. TPH104m remarkably downregulated the phosphorylated and total forms of Drp1 protein in TNBC cells. A docking-based reverse screening approach and Surface Plasmon Resonance (SPR) data indicated that TPH104m binds to Drp1 more strongly than Mdivi-1, a weak non-specific Drp1 inhibitor. A complete and partial Drp1 KO cell line was created in SUM-159 TNBC cells to investigate the role of Drp1 in TPH104m-induced non-apoptotic cell death. Genetically deleting Drp1 from TNBC cells reduced TPH104m's cytotoxic potential suggesting Drp1's role in TPH104m's anticancer mechanism. Moreover, mito-stress assay showed that TPH104m severely impaired oxygen consumption rate, resulting in decreased ATP production and inhibition of mitochondrial respiration. Development of alternative treatments for TNBC will be facilitated by a deeper understanding of mitochondrial role in non-apoptotic cell death.

Turbulence in Zeeman Measurements from Molecular Clouds

Magnetic fields (B fields) play an important role in molecular cloud fragmentation and star formation but are very difficult to detect. The temporal correlation between the field strength (B) and gas density (n) of an isolated cloud has been suggested as an indication of the dynamical importance of B fields relative to self-gravity. This temporal B–n relation is, however, unobservable. What can be observed using Zeeman measurements are the “spatial B–n relations” from the current plane of the sky. Nevertheless, the temporal B–n relation argument has still been widely used to interpret observations. Here we present the first numerical test of the legitimacy of this interpretation. From a simulation that can reproduce the observed Zeeman spatial B ∝ n 2/3 relation, we found that temporal B –n relations of individual cores bear no resemblance to the spatial B –n relations. This result inspired us to discover that the true mechanism behind the 2/3 index is random turbulence compression instead of symmetrical gravitational contraction.

A Comprehensive Analysis of the Research on Blockchain-Enabled Information Sharing Inside a Supply Chain

Abstract: Customers, suppliers, and transporters are just a few of the many stakeholders that make up a supply chain. Due to the rapid expansion of economic globalization and fierce market competition, which has resulted in fragmented information sharing within a supply chain, it is frequently challenging. By utilizing a "single trustworthy ledger," which has the potential to alter the aspect of data trust, blockchain technology may alleviate this issue. The motivation behind this article is to distinguish and fathom the impact of blockchain innovation on store network data sharing. The decentralized design of blockchain innovation gives a serious level of straightforwardness, drawing in interest from various enterprises to carry out this innovation. Utilizing a few information bases, a far reaching survey of the scholastic writing was finished. Blockchain-empowered data trade might get worth to cooperative work a few stock chains, including wellbeing and clinical, development, and shrewd urban communities. As per our outcomes, one potential advantage of utilizing blockchain-empowered data sharing across a store network is that it guarantees all chain members approach checked data, which works on cooperative joint efforts. We recognized potential obstacles to the development of blockchain innovation in production network by means of our top to bottom examination, for example, an absence of consciousness of blockchain innovation in associations and an irreconcilable situation. Future examination, for example, data covering pair with data sharing, could assist with diminishing the hole in taking on this innovation inside a production network. Understanding the qualities of different supply chains is likewise key for really planning for blockchain execution. We acknowledge that our strategy for picking literary works for our efficient audit might have brought about the rejection of specific writings. In any case, we endeavored to incorporate however many important writings as practical to give a guide on the current situation with blockchain-empowered data trade all through a production network
