Classification of Mathematical Poetry
Authors: Rochallyi Radoslav
Published: June 2023

In this statement I aim to create at least a partial classification of mathematical poetry as part of a large group of experimental poetry. I have created a primary classification according to pure mathematics, knowing that it is incomplete and can be extended within and towards other mathematical disciplines, such as applied mathematics or borderline disciplines. All unfamiliar artistic forms in the text are poems themselves. However, it can be used for an analysis of any poem.

Liberdade de expressão, imprensa e mídias sociais: jurisprudência, direito comparado e novos desafios
Authors: Barroso Luís Roberto
Published: June 2023

A liberdade de expressão é uma conquista obtida lenta e paulatinamente no curso da história. No Brasil, esse direito só começa a se afirmar, efetivamente, a partir da Constituição de 1988, em verdadeira reação ao passado e compromisso com o futuro. Este artigo busca apresentar um panorama das principais questões controvertidas relacionadas à liberdade de expressão, passando pelo tratamento destinado na Constituição de 1988, pela jurisprudência do Supremo Tribunal Federal sobre o tema e por breves notas sobre o direito comparado, em especial Estados Unidos e Alemanha. Na parte final, identifico as complexidades despertadas pela Revolução Tecnológica ou Digital, com a popularização da internet e o surgimento das mídias sociais e aplicativos de mensagem. As novas tecnologias, apesar de democratizarem o acesso à informação, abriram caminho para o ódio, a mentira deliberada, a desinformação, a destruição de reputações e as teorias conspiratórias, trazendo novos desafios regulatórios.
Complications in microsurgical breast reconstruction: thrombosis prevention and management
Authors: Inchauste Suzanne M.
Published: June 2023

Breast reconstruction is one of the largest components of plastic and reconstructive surgery. Autologous free flap breast reconstruction continues to grow due to exceptionally high flap success rates. It provides patients with a durable and natural reconstruction with high patient satisfaction. A patent microvascular anastomosis is a key component to a successful autologous free flap breast reconstruction. Thrombus within the vascular anastomosis or the distal flap microcirculation is the most common cause of flap failure. This review aims to discuss microsurgical techniques including atraumatic handling of vessels, appropriate magnification, suture styles, anastomotic techniques, recipient vessel selection, the role of anticoagulation and antiplatelet therapy used to minimize the risk of thrombotic events. When microvascular thrombus occurs, early reoperation and reperfusion is imperative to flap survival. This review will discuss specific maneuvers and intraoperative interventions to maximize flap salvage.
Mechanisms regulating mitochondrial DNA quality control
Authors: Dua Nitish , Badrinarayanan Anjana
Published: June 2023

Maintenance of genome integrity is essential for cellular survival. There are mechanisms utilized by the cells to sense and respond to assaults on genomic DNA. These mechanisms are conserved across all domains of life and are collectively called the DNA damage response pathways. However, eukaryotic cells also have extrachromosomal DNA in mitochondria (mtDNA), which is indispensable for mitochondrial function, and hence cell survival. Indeed, impaired mitochondrial activity arising due to mutations in mtDNA has been found to be associated with many human pathologies. Despite its importance, our understanding of how cells ensure mtDNA genome integrity is limited. Since mitochondria do not encode for machinery required for the maintenance of their own genomes, they depend on the nucleus for replication, transcription, and repair processes. This adds a layer of complexity with the requirement for organelle crosstalk and coordination in response to mtDNA damage. This review summarizes recent findings that provide new insights into mechanisms involved in mtDNA quality control, acting at the level of mtDNA or organelle and also discusses a few new avenues of research towards a comprehensive understanding of the “mtDNA damage response”.
Developed Method. Interactions and Their Quantum Picture
Authors: Ogonowski Piotr
Published: June 2023

By developing the previously proposed method of combining continuum mechanics with Einstein Field Equations, a complete description of the physical system was obtained, which indicates that the descriptions of the system dynamics used in physics do not have to be divergent. The density of the Lagrangian for the system turns out to be equal to the invariant of the electromagnetic field tensor, vanishing four-divergence of canonical four-momentum appears to be consequence of the Poyinting theorem, and explicit form of one of gauges of the electromagnetic four-potential was introduced. A quantum picture of the system was also proposed, leading to the Klein-Gordon equation, which seems to finally reconcile the curvilinear description, flat-spacetime relativistic description and quantum description of the physical system.
Numerical Simulation and Experiment of Stress Relief and Processing Deformation of 2219 Aluminum Alloy Ring
Authors: Li Bianhong , Dong Yushuang , Ouyang Wu , Gao Hanjun
Published: June 2023

Large aluminum alloy ring forgings are the core components of heavy-duty rocket fuel storage tanks, and the large residual stress inside the rings leads to poor shape accuracy of large thin-walled parts. The initial stress of the 2219 aluminum alloy ring blank was tested using the drilling method, and the creep constitutive coefficient of the 2219 aluminum alloy was determined through stress relaxation tests. The numerical simulation processes of thermal stress relief (TSR), vibration stress relief (VSR), and thermal-vibration stress relief (TVSR) were compared and established. Through the correlation analysis between the actual measurement results of residual stress and the simulation results, it can be seen that the strong correlation in three directions at each measurement point accounts for over 37.5%, and the moderate correlation accounts for over 62.5%. This indicates that the numerical simulation model of 2219 aluminum alloy ring containing initial residual stress can accurately reflect the size and distribution of residual stress inside the actual ring. The simulation results show that the derived constitutive model can describe the stress relaxation process of TVSR by combining a single thermal time effect stress relaxation constitutive theory with a VSR plastic deformation material model. The simulation models established above were used to calculate the residual stress homogenization ability of three types of aging. The results showed that VSR, TSR, and TVSR can homogenize and reduce the residual stress field inside the ring, improve the distribution of residual stress inside the ring, and have a better overall homogenization ability of TVSR. The VSR control has a certain effect on reducing and homogenizing residual stress, but compared with TSR and TVSR, the reduction and homogenization ability of residual stress control is limited. The homogenization control effect TVSR>TSR>VSR, and the maximum equivalent stress homogenization rates of VSR, TSR, and TVSR are 52.8%, 80.6%, and 82.2%, respectively. Then, numerical simulation technology is used to study how the initial residual stress in the blank will cause the deformation of the ring during the thin-walled machining process. The roundness error theory of the minimum containment area method is applied to evaluate the deformation degree during the thin-walled numerical machining process, and the TVSR method is used for stress regulation. The deformation law of the thin-walled machining of the ring under different aging parameters is studied.

Published: June 2023

Cooking is a very decentralized and private way of energy consumption in human activities. The existing investigation and statistical analysis can’t effectively calculate the proportion of population relying on clean cooking fuel and utilization technology in the region. Therefore, based on the big data of the earth, this paper adopts the combination of spatial analysis and statistical analysis to determine the survey sample area, and according to the economic conditions, topographic characteristics, national policies for new energy construction and living habits of the provinces and cities under investigation, the questionnaire survey is conducted for the research area to calculate the proportion of the regional population relying on clean cooking fuels and utilization technologies. Taking the south of the Yangtze River in China as an example, the paper effectively calculates that 88.25% of the population depends on clean cooking fuel and technology in this region, of which 89.81% are in urban areas and 79.87% are in rural areas. Analysis of the survey data shows that the proportion of the population using clean cooking fuels and technologies is related to factors such as economic development, income and resource endowment. There is a large urban–rural gap in terms of energy consumption tendency and structure in the south of the Yangtze River in China and cooking energy consumption in rural households also varies from region to region. The technical ideas and conclusions of the paper have high reference application value, which can help promote the upgrading of clean energy utilization and provide data basis for relevant decision and policy making.

Authors: Musyafaah Nurul , Indriana Nilna , Widayanti Rizka , Nuha Muhammad Afthon Ulin
Published: June 2023

The Total Physical Response (TPR) learning method was developed by James J. Asher. He argues that direct pronunciation to children or students contains an order, and then children or students will respond physically before producing verbal or speech responses. The aims of this study were (1) to find out how far speaking skills (mahārat al-kalām) in Arabic have increased through the TPR method in MTsN 4 Jombang, and (2) to find out the supporting and inhibiting factors in increasing mahārat al-kalām through the TPR method in MTsN 4 Jombang. This research method uses a descriptive-qualitative approach with data collection techniques using observation, interviews, documentation, and oral tests. The data analysis technique uses data condensation, data display, and conclusion drawing or verification. The results showed that (1) with the TPR learning method, the final test score of Arabic learning for mahārat al-kalām in cycle 1 was 74.3% (good). After being given referrals again in cycle 2, it reached 87.6% (very good); (2) The supporting factors that influence speaking activities are language (linguistics) and non-linguistics, while the inhibiting factors are more dominant due to a lack of vocabulary (mufradāt) mastery.

Published: June 2023

—The placer deposits of the Miass valley in the Southern Urals have been known since the beginning of the 19th century. Over two centuries of mining more than 120 tons of gold have been extracted from alluvial and alluvial–deluvial placers. Despite the industrial significance of this territory, native gold of alluvial deposits is practically unstudied and there is no data on the mineral composition of concentrates. Native gold and heavy fraction minerals from seven placers of the Miass placer zone of deluvial–alluvial and alluvial types were researched. The study of the typomorphic features of native gold and distribution of heavy fraction minerals in loose deposits makes it possible to determine the genetic types of primary sources of placer formation. Chrome-spinel and ilmenite prevail in the concentrates, magnetite, epidote, rutile, titanite, clinopyroxene, hematite, zircon, garnets, and monazite are less common. Chromespinelides of various placers are represented by chromite and subferrichromite, they are characterized by a high average content of Cr2O3 (50.9 wt.%). Chromespinelide chemical composition features show evidence of its penetration into placer sediments from rocks of the ophiolitic association. The composition and morphological features of phosphates of rare earth elements (monazite and xenotime) indicate their metamorphogenic nature and penetration into placers from the Riphean strata. Native gold is characterized by a low degree of roundness. Mineral inclusions in native gold are represented by sulfides, arsenides, bismuthides, cuprous gold, platinoids. Composition of native gold from the Miass River valley placers varies over a wide range. The main admixtures are silver (4.5–23.4 wt.%) and mercury (up to 5.14 wt.%), copper (up to 2.03 wt.%) was noted in several grains. The EBSD study of native gold internal structure showed predominance of primary crystallization structures, a low degree of deformation and growth of gold-rich rims with a fine-grained mosaic structure. Formation of gold-rich rims in gold grains in placers is explained by recrystallization of the most deformed parts of gold during transportation. Placers occurred due to the destruction of primary sources located in the upper reaches of streams or near them, which is confirmed by a low degree of grains’ roundness. The composition of native gold in combination with a set of micro-inclusions indicate the gold–sulfide-quartz type of mineralization of most primary sources.

Noble metal nanoparticles (NPs) are photo-responsive substrates that generate hot electrons under light excitation, and these hot electrons enhance the catalytic capability of the NPs, which is useful in many applications. For ultrasmall (≤ 5 nm) Pt NPs with excellently catalytic performance, it is challenging to utilize near-infrared (NIR) light-excited hot electrons to enhance the nanozyme activities of Pt NPs for tumor catalytic therapy because ultrasmall Pt NPs have no obvious absorption from the visible light band to the NIR band. Herein, we report on constructing Pt colloidosomes (Cs) with ultrasmall Pt NPs to elevate NIR light absorption to excite multitudes of hot electrons. The successful photon-to-electron conversion is based on the high density of electron states (d-band) at the Fermi energy in the Pt system, which leads to a high probability of generating NIR photon-excited hot electrons. NIR light absorption of Pt Cs is optimized by introducing grain boundaries (GBs) defects in Mn3O4 precursors by laser irradiation in liquids. Moreover, NIR photon-excited hot electrons largely promote the self-cascade catalytic production of reactive oxygen species (ROS) for enhanced tumor therapy. This study first validates the generation of hot electrons in the Pt nanostructure under NIR light irradiation by assembling ultrasmall Pt NPs, and then demonstrates the Pt Cs to be highly promising as efficient photo-responsive nanozymes with integrated photoactivity and chemical activity.

Published: June 2023

Increasing carbon emissions have accelerated climate change, resulting in devastating effects that have become tangible on an everyday basis1. This is mirrored by a projected increase in global energy demand by ca. 50% in a single generation timespan2,3, urging a shift from fossil-fuel derived materials toward greener materials and more sustainable manufacturing processes4. Bio-based industrial byproducts, such as food industry side-streams5, are attractive alternatives with a strong potential for valorization owing to their large volume, low cost, renewability, biodegradability, and intrinsic material properties6. Here we demonstrate the reutilization of industrial chicken feathers waste into proton conductive membranes for fuel cells7, protonic transistors8, and water-splitting devices9. Keratin was isolated from chicken feathers via a fast and economical process, converted into amyloid fibrils upon heat treatment, and further processed into membranes with imparted proton conductivity through a simple oxidative method10. The functionality of the membranes is demonstrated by assembling them into a hydrogen fuel cell capable of powering several types of devices using hydrogen and air as fuel. Additionally, these membranes could be used to generate hydrogen by water splitting, and in protonic field-effect transistors as a thin-film modulating protonic conductivity via the electrostatic gating effect. We believe that by converting industrial waste into renewable energy materials at low cost and high scalability, our green manufacturing process can contribute to a fully circular economy with neutral carbon footprint.

Introduction: Kenya reported its first COVID-19 case on March 13, 2020. Pandemic-driven health system changes followed, as did mitigation measures. These measures had unintended health, economic, and societal consequences: Kenyan women in paid and unpaid employment bore the brunt. This protocol aims to identify potential gender equality and health equity gaps, and possible disproportional health and socio-economic impacts experienced by paid and unpaid female health care providers in Kilifi and Mombasa Counties during the COVID − 19 pandemic. It will also identify evidence-based policy options for future safeguarding of the unpaid and paid female health work force during emergency preparedness, response and recovery periods. Methods: Participatory mixed methods framed by a health equity, gender analysis and human-centred design will be used to engage the unpaid and paid health workforce in the research. Research implementation will follow four of the five phases of the human centred design approach which include, empathize phase, define phase, ideate &synthesis phase, prototype/critical review phase, and testing phase. Data collection in the empathize phase will utilize qualitative (focus group discussions and in-depth interviews) and quantitative (survey questionnaire) to explore perceptions, experiences, needs and priorities of health care providers in relation to COVID-19. This will then be further explored and contextualised in the define phase. In the ideate& synthesis phase, workshops with key stakeholders and health care providers will brainstorm and propose as many gender equitable and transformative recovery solutions as possible for future pandemic preparedness based on the findings from the define phase. In the prototype and critical review phase, the solutions proposed will then be critically appraised and packaged as policy and strategic recommendations that are gender- sensitive and transformative. Community research advisory groups and local advisory boards will be established to ensure integration and sustainability of the participatory research design. Discussion: Globally, seven out of ten health workers are women. This study will generate evidence on root cultural, structural, socio-economic and political factors that perpetuate gender inequities and female disadvantage in the paid and unpaid health sector. Such evidence is critical for the realization of women’s rights, well-being and livelihoods, and for development of gender- sensitive and transformative health systems that can withstand future emergencies and structural shocks.
Formation of porous Ga oxide with high-aspect-ratio nanoholes by anodizing single Ga crystal
Authors: Kondo Toshiaki
Published: June 2023

We developed a simple crystal growth process to obtain a single Ga crystal. The crystal orientation of a Ga plate could be controlled by a crystal growth process using a seed Ga crystal. By anodizing a [100]-direction highly oriented Ga plate, we realized the formation of a highly ordered array of high-aspect-ratio straight nanoholes. It was observed that the nanohole growth direction depends on the crystal orientation of a Ga plate. To date, this dependence has yet to be observed in materials other than porous Ga oxide obtained by an anodization process. The present fabrication process is expected to be applied to the fabrication of various functional devices requiring a porous Ga oxide with high-aspect-ratio straight nanoholes, such as hydrogen formation devices and functional filters.

Published: June 2023

Background：With the development of technological innovation, research ideas, and society, the quality of life of the elderly in China has begun to show a trend of volatility and instability. Related factors affecting service satisfaction of the elderly should be revisited and studied based on new perspectives and new theories. After re-examining, especially after the concept of network society is put forward as an important field of social livelihood and social services, the system of influencing factors and corresponding theoretical systems of elderly service satisfaction should also be sublimated.
Goal: Investigate various factors that affect the satisfaction of retired elderly services, compare with the traditional influencing factor system, and explore the mechanism of Internet factors.
Method: This article is based on China Comprehensive Social Survey Data (CGSS), from a networked perspective, using descriptive statistical analysis, stepwise regression, factor analysis, comparative analysis, and interactive analysis to investigate the impact on elderly service satisfaction to explore the role of the new influencing factor of Internet usage.
Results: Research shows that the important influencing factor system of elderly services satisfaction includes not only traditional factors such as income and age, but also new technological factors such as the Internet; the significant impact of this technological factor only appeared in 2015; the Internet's influence on elderly servicess and the impact of satisfaction has a dual effect, namely direct and indirect.
Conclusion: It means that in order to improve the service satisfaction of the elderly, it is necessary to pay attention to the improvement of traditional influencing factors on the one hand, and to give full play to the value of network technology on the other hand.

Lakhimi is a very promising indigenous dual cattle breed of Assam, India, with their superior draught power capacity, heat tolerance, disease resistance, and adaptability to harsh agro-climatic conditions. The present study was designed to monitor the ovarian follicular dynamics and hormonal profile during the estrus cycle in Lakhimi cows. The study revealed that two follicular wave cycles were predominant (66.7%) in Lakhimi cows with the least duration of ovulatory wave in both two and three-wave cycles. The emergence of wave in the two-wave cycle was 1.16 ± 0.30 and 10.83 ± 0.47 while in three wave cycle on day 0.83 ± 0.16, 7.33 ± 0.49, and 12.16 ± 0.47 of the cycle. The number of the antral follicular count was more in two waves estrous cycle (4.33 ± 0.49 number in the ovulatory wave) compare to three wave cycle with 3.66 ± 0.33 number of follicles. The maximum size of the DF two and three follicular waves were 11.51 ± 0.54 mm and 12.41 ± 0.69 mm respectively. The hormonal dynamics were characterized by peak progesterone concentration (ng/ml) on day 10th day. estradiol on the 20th (the day before estrous) and the day of heat, and LH peak on the 1st day of estrous with subsequent low concentration in Lakhimi Cows. So ovarian follicular waves in Lakhimi cows were characterized by two wave cycles with a low antral follicular count, less diameter of DF, and lower concentration of LH, Progesterone, and estradiol.

Published: June 2023

Objective The aim of this study is to investigate the impact of exercise on intermediate disease markers in populations with overweight and obese, providing evidence-based recommendations for clinicians to utilize these markers in developing exercise prescriptions for this group. Methods The study was conducted by retrieving data from PubMed, Embase, Cochrane Library, Web of Science, and CNKI and only including Randomized Controlled Trials (RCTs) to examine the effect of different exercise interventions on intermediate disease markers in overweight and obese people. The quality of the included studies was evaluated using the Cochrane Bias Risk Assessment tool and the data was analyzed using Stata 15.1 data analysis software. Results The RCTs were collected from January 2017 to December 2022. A total of 55 RCTs were included and the results of 10 outcomes were analyzed using random effects meta-analysis. The total sample size used in the study was 3,122 The results showed that resistance training significantly reduced total cholesterol (SUCRA: 99.9%), triglycerides (SUCRA: 100.0%), low-density lipoprotein (SUCRA: 100.0%), systolic pressure (SUCRA: 92.5%), and increased high-density lipoprotein (SUCRA: 100.0%). Aerobic exercise significantly reduced insulin (SUCRA: 89.1%) and HbA1c (SUCRA: 95.3%). Concurrent training significantly reduced HOMA-IR (SUCRA: 93.8%), diastolic blood pressure (SUCRA: 71.2%) and Glucose (SUCRA:87.6%). Conclusion Exercise has a significant impact on intermediate disease markers in populations with overweight and obese. Compared with no exercise, exercise lowers total cholesterol, triglycerides, LDL, systolic blood pressure, diastolic blood pressure, HOMA-IR, insulin, and HbA1c, and increases HDL in people with overweight and obese. These findings provide evidence-based recommendations for exercise interventions aimed at weight reduction and the prevention of chronic diseases in individuals with overweight and obese.

Authors: Katayama Hiroyuki , Yasui Midori
Published: June 2023

The implementation of precoagulation prior to the physical removal process is expected to attain a high virus removal rate. However, a risk exists for viruses to form small flocs and subsequently escape into the effluent of physical removal processes. This study evaluated how the virus in the microflocs could be quantified by conventional virus quantification methods (Plaque assay and quantitative PCR (qPCR) assay). In this study, the microflocs dissolution phenomenon in a phosphate buffer solution was employed as a floc dissolving test and virus concentrations before and after floc dissolving were quantified. The findings revealed an increase in virus concentrations by > 1.0 − >3.9 log pfu/ml by the Plaque assay and by 1.7 − >4.0 log copies/ml by the qPCR assay, following the dissolution of microflocs prepared in the humic acid test water. In the case of treated wastewater, the concentration increases were confirmed in all samples by the Plaque assay and in 7 out of 8 samples by the qPCR assay. Fewer viruses were detected in the microflocs that remained undissolved by either Plaque assay or qPCR assay.

Published: June 2023

Riparian vegetation can be a suitable option for the flood control and sustainable river managementas it is beneficial for the energy dissipation of flows. The present experimental investigation is aimed at understanding the flow field and energy dissipation of flows in the presence of rigid and flexible vegetation. Physical laboratory-based models are tested in a rectangular flume to observe the flow field in upstream and downstream of both rigid and flexible vegetated streams. Rigid vegetation is simulated by wooden dowels of equal height and almost uniform diameter in this study whereas for flexible vegetation paddy plants are used. These vegetations are installed in a wooden box and fixed in middle of the channel. A constant discharge ismaintained throughout the experiment. Acoustic Doppler Velocimeter is utilized to inspect the three-dimensional velocities and flow configuration in upstream and downstream of the both rigid and flexible vegetations. The velocity profile isthen compared for both flexible and rigid vegetation. The velocity retardation near and within vegetation for the flexible vegetative model is found to be nearly 90%, whereas for the rigid model, it is around 24%. Additionally, energy dissipation at all the sections of both the vegetation typeis found to get a more comprehensive understanding of the flow field.Overall, this study observed that there is reduction in the stream velocity due to vegetation, which further decreases scouring in the channel, thereby reducing erosion and sediment discontinuity.

In this study an electrochemical device for lead ion based on an amine-functionalized Zr (IV) metal-organic framework (UiO-66-NH2) and polypyrrole (PPy) composite nanomaterials were prepared. The morphological characteristics and internal structural information of UiO-66-NH2@PPy composites were obtained through instruments such as scanning electron microscopy (SEM), high-resolution transmission electron microscope (TEM), multifunctional high-resolution X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, X-ray photoelectron spectrometer (XPS), nitrogen adsorption/desorption analyzer, and thermogravimetric analyzer (TGA). The outstanding electrochemical performance of the electrochemical device prepared was attributed to the large specific surface area and abundant amino binding sites of UiO-66-NH2, and the excellent conductivity of PPy. Under optimal experiment conditions, the detection limit of the electrochemical device for lead ions is as low as 0.05 µg/L, with a good response in the linear range of 0.1–256 µg/L. Finally, we used this sensor to detect the content of lead ions in pig kidneys and compared it with standard methods. The results show that our sensor is simple, reliable and provides an alternative solution for the analysis of lead ions in meat.

For the determination of tin(II) traces, an extractive spectrophotometric approach is devised. The applied method serves a powerful tool for determination of tin(II), involves the formation of yellow colored complex among the 6-bromo-3-hydroxy-2-(5-methylfuran-2-yl)-4H-chromen-4-one (BHMF) and tin(II) in 1:2 stiochiometry in a slightly acidic medium (HCl). The complex shows absorbance at 434 nm in respect of the blank reagent. The outcomes of spectral investigation for complexation showed a Beer’s range of 0-1.3 µg Sn mL− 1, molar absorptivity, specific absorptivity and Sandell’s complex sensitivity are 9.291 × 104 L mol− 1cm− 1, 0.490 mL g− 1cm− 1 and 0.002040 µg cm− 2 at 434 nm and stable for up to two days.The interferences studyresults showed that this method is free from interferences, when tested with metal ions including Ag,Be, Bi, Ca,Cd, Ce, Co,Hg, Mo,Re,Pt, Se,Ti,U,V, W and other common cations, anions, and complexing agents. The method is quite simple, highly selective, and sensitive with good re-producibility. The method has been satisfactorily by utilizing the proposed procedure, and its applicability has been tested by analyzing synthetic samples and an alloy sample of gunmetal. The procedure assumes this because of the scarcity of better methods for determining tin(II). The results are in good agreement with the certified value.

Cation intercalation is an effective method to optimize the electronic structures of metal oxides, but manipulating the intercalation structure and conductivity is difficult. Here, we report a visual topochemical synthesis strategy to control the intercalation pathways, structures, and conductivity, and realize rapid synthesis of flexible conductive metal oxide films in 1 min at room-temperature. This study uses a flexible topological TiO2 nanofiber film as the prototype and designs three different charge-driven models to intercalate the preset Li+-ions into the TiO2 lattice slowly (µm/s), rapidly (mm/s) or ultrafast (cm/s). The Li+-intercalation causes real-time color changes of the TiO2 films from white to blue and then black, corresponding to the new structures of blue LixTiO2 and black TiO2-δ derived in TiO2, and the enhanced conductivity from 0 to 1 and 40 S/m. This work realizes the rapid synthesis of flexible TiO2 nanofiber films with tunable conductivity on large-scale and has been extended to synthesize other conductive metal oxide films for appealing applications in fast-charge electrodes, electrochromic pattern designs, catalysis and so on.

BackgroundHeart disease is a leading cause of mortality worldwide, including in Indonesia. With millions of deaths attributed to heart disease annually, early detection and prevention are essential in reducing its impact. This study aims to address the issue of late diagnosis by focusing on early detection and monitoring of heart disease symptoms. Risk factors such as high blood pressure, high cholesterol, smoking, obesity, and sedentary lifestyle contribute to the development of heart disease.FindingsMany patients with heart disease are diagnosed at advanced stages, indicating a lack of timely detection. To overcome this, the study utilizes Medical Check-Up Datasets and applies the Multilayer Perceptron (MLP) Classifier with back-propagation for early diagnosis. The MLP Classifier employs supervised learning during training and testing, where a value of 1 represents abnormal (presence of heart disease) and 0 represents normal (absence of heart disease). The study achieves an accuracy of 99.2% in early detection.ConclusionThe findings of this study demonstrate the feasibility and significance of early detection in heart disease diagnosis. By using the MLP Classifier, healthcare providers can promptly identify and address heart disease symptoms, enabling appropriate treatment planning and reducing the risk of complications. These results provide valuable insights for healthcare professionals, contributing to improved patient care and outcomes.
Seasonal Drivers of Nutrient Concentration in Lake Ecosystems: Evaluating Climate and Ice Phenology Characteristics in a Shallow Eutrophic Lake

The climate is shifting across the globe and understanding seasonal drivers of nutrient concentration in lake ecosystems is important to further our understanding of drivers of biotic change. Additionally, the degree to which winter dynamics in lake ecosystems respond to climate and ecosystem level factors and their role in influencing nutrient cycling processes is unclear but important for understanding and managing potential changes. The overall objective of this study was to evaluate seasonal water column nutrient concentrations, climatic conditions, and ice phenology characteristics in a small shallow eutrophic lake. Water column nutrients were sampled from October 2009 to September 2020 at two locations at Petit-lac-Saint-François (Lake Inlet and Lake Outlet) in south-central Quebec, Canada. During this sampling period, ice phenology characteristics and phytoplankton samples were also collected. The degree of correlation with nutrient concentrations varied between climate indices across different time scales and monitoring locations. The timing of lake ice varied during the study period ranging from 102 to 166 days of ice coverage with the duration of ice coverage being significantly correlated with dissolved inorganic nutrient accumulation during the ice-on period. Moreover, phytoplankton composition varied between ice-on/off periods and species richness significantly declined. Studies that evaluate winter limnological characteristics are limited but important to understand the seasonal dynamics of nutrient cycling in these systems, especially given how the climate is shifting. Moreover, the climate is a significant driver of lake biogeochemical with respect to both inputs and internal processes.

Background
Given the importance of preventive care for the lower limb in people with diabetes, and the absence of local guidelines in Aotearoa New Zealand (NZ), the aim of this study was to determine the alignment of assessment and management used in the prevention of diabetes-related foot disease by NZ podiatrists to the international prevention guideline recommendations.
Methods
A 37-item web-based survey was developed using a 5-point Likert scale (0 = always; 5 = never) based on the International Working Group of the Diabetic Foot (IWGDF) 2019 prevention guidelines and included domains on participant demographics, sector, caseloads, guidelines, screening, management, education, and referral. The survey was distributed to NZ podiatrists through the NZ podiatry association and social media. Participants completing > 50% of items were included. The Mann-Whitney U test was used to examine differences between sector subgroups.
Results
Seventy-seven responses (16.3% of the NZ workforce) were received, of which 52 completed > 50% of items and were included. Of those 52 podiatrists, 73% were from the private sector. Public sector podiatrists reported higher weekly caseloads of patients with diabetes (p = 0.03) and foot ulcers (p < 0.001). The NZSSD risk stratification system and IWGDF guidelines were the two most frequently utilised guidance documents. Participants reported median scores of at least “often” (< 2) for all items in the assessment and management, inspection, examination, and education provision domains for people with a high-risk foot. More than 50% of respondents reported screening more frequently than guideline recommendations for people with a very low to moderate risk foot. Structured education program was only used by 4 (5%) participants. Public sector podiatrists reported greater provision of custom-made footwear (p = 0.04) and multi-disciplinary team care (p = 0.03).
Conclusion
NZ podiatrists generally follow international guideline recommendations with respect to screening, self-care education, appropriate footwear, and treatment of risk factors for people at-risk of diabetes-related foot disease. However there may be over-screening of people with very low to medium risk occurring in clinical practice. Increasing access to integrated healthcare, custom-made footwear and structured educational programmes appear to be areas of practice that could be developed in future to help prevent diabetes-related foot disease in NZ.
