Chronic Energy Deficiency (CED) often affects women of childbearing age. The Local Area Monitoring Report of mothers for Karang Pule Health Center in November 2021 found 5.74% (19 people out of 73 pregnant women) experienced The purpose of this service was to increase awareness and the eating behavior of women of childbearing age.The service activity "Counseling on the diet of women of childbearing age" used method which begins with identification of eating patterns and ends with an evaluation of changes in women of childbearing age weight that is carried out in the Dasan Kolo environment, Jempong Baru village. After the dedication, there was an increase in women of childbearing age weight by 1 kg at 66.67% women of childbearing age and there was 33.33% women of childbearing age weight by 2 kg at. This increase in women of childbearing age weight indicated that counseling on women of childbearing age diets was able to change the dietary behavior who experience CED. It is hoped that women of childbearing age can adopt a diet in accordance with the recommended number of servings of adequate energy and protein that has been understood. In addition, the study program can follow up by observing and evaluating the eating behavior of female students who have received this counseling.

A novel esophageal retractor with eccentric balloon during atrial fibrillation ablation.

Due to the anatomically adjacent relationship between the left atrium (LA) and esophagus, energy delivery on the posterior wall of LA is limited. The aim of this study was to evaluate the feasibility of a novel esophageal retractor (SAFER) with an inflatable C-curve balloon during atrial fibrillation (AF) ablation. Nine patients underwent AF ablation assisted with the SAFER. After inflation, the esophagus was deviated laterally away from the intended ablation site of the posterior wall under local anesthesia. The extent of mechanical esophageal deviation (MED) was evaluated under fluoroscopy, defined as the shortest distance from the trailing esophageal edge to the closest point of the ablation line. Gastroscopy was performed before and after ablation. The target ablation index used in all LA sites including the posterior wall was 400-450 after effective MED. All adverse events during the periprocedural period were recorded. The mean deviation distance achieved 16.2±9.6mm away from the closest ablation point of the pulmonary vein lesion set. With respect to the individual left and right pulmonary vein lesion sets, the deviation distance was 19.7±11.5 and 12.7±6.8mm, respectively. The extent of deviation was 0 to 5mm, 5.1 to 10mm, or>10mm in 0(0%), 7(38.9%), and 11(61.1%), respectively. Procedural success was achieved in all patients without acute reconnection. There was only one esophageal complication which manifested as esophageal erosion and this patient experienced throat pain possibly related to the SAFER retractor with no clinical sequelae. Esophageal deviation with the novel eccentric balloon is a novel feasible choice during AF ablation, enabling adequate energy delivery to the posterior wall of LA. Additional prospective randomized controlled studies are required for further validation.

Factors explaining seasonal variation in energy intake: a review.

Maintaining a balance between energy intake and expenditure is crucial for overall health. There are seasonal variations in energy intake, with an increase during spring and winter as well as a decrease during summer. These variations are related to a combination of environmental factors, including changes in temperature and daylight hours; social factors, including events and holidays; and physiological factors, including changes in physical activity and emotions. Accordingly, this review aimed to summarize the environmental, social, and physiological factors that contribute to seasonal variations in energy intake. A review of the current literature revealed that changes in temperature and daylight hours may affect eating behavior by altering homeostatic responses and appetite-related hormones. Additionally, increased participation in events and frequency of eating out, especially during winter vacations, may contribute to increased energy intake. Notably, these findings may not be generalisable to all populations since environmental and social factors can vary significantly depending on the local climatic zones and cultural backgrounds. The findings of the present review indicate that seasonal climate, events, and associated hormonal changes should be taken into account in order to maintain adequate energy intake throughout the year.

A Software Framework for Intelligent Security Measures Regarding Sensor Data in the Context of Ambient Assisted Technology.

Ambient assisted technology (AAT), which has the potential to enhance patient care and productivity and save costs, has emerged as a strategic goal for developing e-healthcare in the future. However, since the healthcare sensor must be interconnected with other systems at different network tiers, distant enemies have additional options to attack. Data and resources integrated into the AAT are vulnerable to security risks that might compromise privacy, integrity, and availability. The gadgets and network sensor devices are layered with clinical data since they save personal information such as patients' names, addresses, and medical histories. Considering the volume of data, it is difficult to ensure its confidentiality and security. As sensing devices are deployed over a wider region, protecting the privacy of the collected data becomes more difficult. The current study proposes a lightweight security mechanism to ensure the data's confidentiality and integrity of the data in ambient-assisted technology. In the current study, the data are encrypted by the master node with adequate residual energy, and the master node is responsible for encrypting the data using the data aggregation model using a node's key generated using an exclusive basis system and a Chinese remainder theorem. The integrity of the data is evaluated using the hash function at each intermediate node. The current study defines the design model's layered architecture and layer-wise services. The model is further analyzed using various evaluation metrics, such as energy consumption, network delay, network overhead, time in generating hash, tradeoff between encryption and decryption, and entropy metrics. The model is shown to adequately perform on all measures considered in the analysis.

Muscle transcriptome analysis provides new insights into the growth gap between fast- and slow-growing Sinocyclocheilus grahami.

Sinocyclocheilus grahami is an economically valuable and famous fish in Yunnan Province, China. However, given its slow growth (40g/2 years) and large growth differences among individuals, its growth performance needs to be improved for sustainable future use, in which molecular breeding technology can play an important role. In the current study, we conducted muscle transcriptomic analysis to investigate the growth gaps among individuals and the mechanism underlying growth within 14 fast- and 14 slow-growth S. grahami. In total, 1,647 differentially expressed genes (DEGs) were obtained, including 947 up-regulated and 700 down-regulated DEGs in fast-growth group. Most DEGs were significantly enriched in ECM-receptor interaction, starch and sucrose metabolism, glycolysis/gluconeogenesis, pyruvate metabolism, amino acids biosynthesis and metabolism, peroxisome, and PPAR signaling pathway. Some genes related to glycogen degradation, glucose transport, and glycolysis (e.g., adipoq, prkag1, slc2a1, agl, pygm, pgm1, pfkm, gapdh, aldoa, pgk1, pgam2, bpgm, and eno3) were up-regulated, while some genes related to fatty acid degradation and transport (e.g., acox1, acaa1, fabp1b.1, slc27a1, and slc27a2) and amino acid metabolism (e.g., agxt, shmt1, glula, and cth) were down-regulated in the fast-growth group. Weighted gene co-expression network analysis identified col1a1, col1a2, col5a1, col6a2, col10a1, col26a1, bglap, and krt15 as crucial genes for S. grahami growth. Several genes related to bone and muscle growth (e.g., bmp2, bmp3, tgfb1, tgfb2, gdf10, and myog) were also up-regulated in the fast-growth group. These results suggest that fast-growth fish may uptake adequate energy (e.g., glucose, fatty acid, and amino acids) from fodder, with excess energy substances used to synthesize collagen to accelerate bone and muscle growth after normal life activities are maintained. Moreover, energy uptake may be the root cause, while collagen synthesis may be the direct reason for the growth gap between fast- and slow-growth fish. Hence, improving food intake and collagen synthesis may be crucial for accelerating S. grahami growth, and further research is required to fully understand and confirm these associations.

Mechanism of PGC-1α-mediated mitochondrial biogenesis in cerebral ischemia-reperfusion injury.

Cerebral ischemia-reperfusion injury (CIRI) is a series of cascade reactions that occur after blood flow recanalization in the ischemic zone in patients with cerebral infarction, causing an imbalance in intracellular homeostasis through multiple pathologies such as increased oxygen free radicals, inflammatory response, calcium overload, and impaired energy metabolism, leading to mitochondrial dysfunction and ultimately apoptosis. Rescue of reversibly damaged neurons in the ischemic hemispheric zone is the key to saving brain infarction and reducing neurological deficits. Complex and active neurological functions are highly dependent on an adequate energy supply from mitochondria. Mitochondrial biogenesis (MB), a process that generates new functional mitochondria and restores normal mitochondrial function by replacing damaged mitochondria, is a major mechanism for maintaining intra-mitochondrial homeostasis and is involved in mitochondrial quality control to ameliorate mitochondrial dysfunction and thus protects against CIRI. The main regulator of MB is peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), which improves mitochondrial function to protect against CIRI by activating its downstream nuclear respiratory factor 1 (NRF1) and mitochondrial transcription factor A (TFAM) to promote mitochondrial genome replication and transcription. This paper provides a theoretical reference for the treatment of neurological impairment caused by CIRI by discussing the mechanisms of mitochondrial biogenesis during cerebral ischemia-reperfusion injury.

Bayesian analysis-based ground motion prediction equations for earthquake input energy

Earthquake energy-based procedures offer a promising alternative for seismic evaluation and earthquake-resistant design of structures. Accurate determination of earthquake energy demand and the provision of an adequate energy supply to the structural system are crucial for this approach. This is where the utilization of ground motion prediction equations (GMPEs) becomes essential in achieving accurate assessment of seismic demands on structures. However, most GMPEs primarily focus on determining spectral accelerations. This study proposes a methodology to derive GMPEs by combining the Fourier amplitude spectrum, the elastic input energy spectrum, and Bayesian regression analysis. These GMPEs estimate energy-based spectral values for interplate and intraslab earthquakes recorded in the firm ground of Mexico City. Furthermore, a mathematical expression is devised to determine correlation coefficients between energy-based spectral values for interplate and intraslab earthquakes, expanding the GMPEs' applicability. Finally, a probabilistic seismic hazard analysis is conducted using the proposed GMPEs and the correlation model.

Can Nutrition Contribute to a Reduction in Sarcopenia, Frailty, and Comorbidities in a Super-Aged Society?

Many countries are facing the advent of super-aging societies, where sarcopenia and frailty will become pertinent problems. The prevalence of comorbidities is a major problem in countries with aged populations as elderly people suffer from various diseases, such as diabetes, heart failure, chronic kidney disease and dementia. All of these diseases are associated with sarcopenia and frailty, and they frequently cause falls, fractures, and a decline in activities of daily living. Fractures in the elderly people are associated with bone fragility, which is influenced by diabetes and chronic kidney disease. Nutritional support for chronic disease patients and sarcopenic individuals with adequate energy and protein intake, vitamin D supplementation, blood glucose level management for individuals with diabetes, obesity prevention, nutritional education for healthy individuals, and the enlightenment of society could be crucial to solve the health-related problems in super-aging societies.

The Predictive Roles Of Leadership And Communicating Religious Commitment In Energy Sustainability Change Readiness

Industrial fields of Indonesia are facing challenging issues of energy sustainability. As the country’s second-largest energy consumer behind the transportation sector, industrial’s consumption is massively dominated by non-renewable energy and the lack of adequate energy waste management. Organizations need to build employee readiness to change toward energy sustainability. Leadership is reasonably a significant predictor of organizational change readiness (RtC). Religious commitment (RC) emerges as a personal motivator for pro-environmental behaviour because individuals perceive looking after nature and the environment as adhering to religious values and teachings. The society of Indonesia views religiosity as a virtue and values social hierarchy as one of the most substantial social structures. Accordingly, this study aims to examine the predictive roles of leadership and RC on organizational RtC and the features in communicating both predictors in change leadership. A mix-method approach was carried out by delivering questionnaires (N=257), conducting interviews, and focus group discussions with 35 managers and employees in the textile industry. A significant influence of leadership on RtC is found, strengthened by the impact of RC. Qualitative findings depicted religious meanings of energy sustainability and how leaders communicate their religiosity in employee behavioral changes.

Low energy availability reduces myofibrillar and sarcoplasmic muscle protein synthesis in trained females.

Low energy availability (LEA) describes a state where the energy intake is insufficient to cover the energy costs of both exercise energy expenditure and basal physiological body functions. LEA has been associated with various physiological consequences, such as reproductive dysfunction. However, the effect of LEA on skeletal muscle protein synthesis in females performing exercise training is still poorly understood. We conducted a randomized controlled trial to investigate the impact of LEA on daily integrated myofibrillar and sarcoplasmic muscle protein synthesis in trained females. Thirty eumenorrheic females were matched based on training history and randomized to undergo 10days of LEA (25kcal·kg fat-free mass (FFM)-1 ·day-1 ) or optimal energy availability (OEA, 50kcal·kg FFM-1 ·day-1 ). Before the intervention, both groups underwent a 5-day 'run-in' period with OEA. All foods were provided throughout the experimental period with a protein content of 2.2gkg lean mass-1 ·day-1 . A standardized, supervised combined resistance and cardiovascular exercise training programme was performed over the experimental period. Daily integrated muscle protein synthesis was measured by deuterium oxide (D2 O) consumption along with changes in body composition, resting metabolic rate, blood biomarkers and 24h nitrogen balance. We found that LEA reduced daily integrated myofibrillar and sarcoplasmic muscle protein synthesis compared with OEA. Concomitant reductions were observed in lean mass, urinary nitrogen balance, free androgen index, thyroid hormone concentrations and resting metabolic rate following LEA. These results highlight that LEA may negatively affect skeletal muscle adaptations in females performing exercise training. KEY POINTS: Low energy availability (LEA) with potential health and performance impairments is widespread among female athletes. We investigated the impact of 10days of LEA on daily integrated myofibrillar and sarcoplasmic muscle protein synthesis in young, trained females. We show that LEA impairs myofibrillar and sarcoplasmic muscle protein synthesis in trained females performing exercise training. These findings suggest that LEA may have negative consequences for skeletal muscle adaptations and highlight the importance of ensuring adequate energy availability in female athletes.

Good Words, Corrupt Words, and Publishing Etiquette

Adhering to the demands of integrity and having research attitudes rooted in moral sensibilities are of paramount importance for academics, researchers, and writers. Publishing etiquette requires them to invest adequate time and energy in conducting research and writing manuscripts and thus to produce beneficial knowledge. Putting together a document hastily and avoiding the much-needed effort in research and writing lead to negative outcomes. The corrupt practice of plagiarism and the desire for recognition through fraudulent and duplicitous publications are marked by deliberate deceptiveness. It debases the plagiarists, stagnates their intellectual growth, and vitiates the academic environment. Highlighting this observation, in this essay I shall discuss some dimensions and significance of publishing etiquette. I shall argue that attitudes and behaviours of researchers and academic practitioners determine the quality of the words and works that they produce.

Nutritional Adequacy and Patient Perceptions of the Hospital Inpatient Haemodialysis Menu: A Mixed Methods Case Series

Aim: To evaluate the nutritional adequacy of the hospital haemodialysis menu, quantify the dietary intake of hospitalised haemodialysis patients and explore patient perceptions of the menu. Methods: The menu analysis compared the default menu to reference standards using a one sample t-test via SPSS. Eight hospitalised haemodialysis patients were purposively interviewed using semi-structured interviews. Thematic analysis was used to identify the dominant themes. The participant’s actual dietary intake was calculated and compared to individual nutrients using evidence-based guidelines. Results: Compared to the reference standards, the default inpatient haemodialysis menu did not provide adequate energy (p < 0.001, mean = 8767 kJ/day ± 362), sodium (p < 0.001, mean = 72 mmol/day ± 9), potassium (p < 0.001, mean = 64 mmol/day ± 4), vitamin C (p ≤ 0.001, mean = 33 mg/day ± 10) and fibre (p < 0.001, mean = 26 g/day ± 3). Inadequate intake of energy and protein occurred in half of the participants. Passive acceptance of the menu, environmental and cultural considerations contributed to missed food opportunities impacting the patient experience and limited intake. Conclusions: The profile of the current default inpatient haemodialysis menu impacts the dietary intake and the experience of haemodialysis inpatients. It is recommended that the default menu is optimised in line with evidence-based guidelines for inpatients.

Study on self-centering mechanism of different yield strength hybrid buckling restrained braces

Conventional buckling-restrained braces (BRBs) exhibit stable compressive and tensile strengths and excellent energy dissipation characteristics. Nevertheless, the low post-yield stiffness limits the capacity of BRBs to control the peak displacement of the structure. This leads to large residual displacements in structures, which increases the probability of collapse under strong earthquakes. Consequently, introducing a reliable system that dissipates seismic energy, and provides an adequate self-centering capability, is necessary. This study has been carried out to investigate the hybrid BRBs response with different yield strengths (DY-HBRB) using numerical analysis. The cyclic responses, residual displacement, energy dissipation, and equivalent damping coefficient of the DY-HBRB models have been assessed. A simplified core-spring finite element model was utilized to model DY-HBRB elements. Moreover, an innovative trilinear kinematic hysteresis (TKH) model is proposed to simulate the cyclic behavior and facilitate the application of DY-HBRBs to seismic designs. The proposed model has been validated with the experimental investigation and numerical analysis results. The results indicate that selecting appropriate combinations of steel cores with different yield strengths in DY-HBRB provides a stable cyclic response with adequate energy dissipation and eliminates a significant part of the residual displacement. In addition, it was confirmed that the proposed TKH model could logically represent the double yield point of the DY-HBRBs with remarkable precision.

The role of mitochondrial dysfunction in periodontitis: From mechanisms to therapeutic strategy.

Periodontitis is an inflammatory and destructive disease of tooth-supporting tissue and has become the leading cause of adult tooth loss. The most central pathological features of periodontitis are tissue damage and inflammatory reaction. As the energy metabolism center of eukaryotic cells, mitochondrion plays a notable role in various processes, such as cell function and inflammatory response. When the intracellular homeostasis of mitochondrion is disrupted, it can lead to mitochondrial dysfunction and inability to generate adequate energy to maintain basic cellular biochemical reactions. Recent studies have revealed that mitochondrial dysfunction is closely related to the initiation and development of periodontitis. The excessive production of mitochondrial reactive oxygen species, imbalance of mitochondrial biogenesis and dynamics, mitophagy and mitochondrial DNA damage can all affect the development and progression of periodontitis. Thus, targeted mitochondrial therapy is potentially promising in periodontitis treatment. In this review, we summarize the above mitochondrial mechanism in the pathogenesis of periodontitis and discuss some potential approaches that can exert therapeutic effects on periodontitis by modulating mitochondrial activity. The understanding and summary of mitochondrial dysfunction in periodontitis might provide new research directions for pathological intervention or treatment of periodontitis.

Body Mass Index Categories Among Pregnant Women Attending Primary Health Care Centers / Baghdad 2022

Background: Recommended weight gain to support a healthy pregnancy vary by prepregnant body mass index. Insufficient weight gain especially associated with prepregnant underweight is associated with increased risk of spontaneous preterm delivery, small for gestational age. Extensive weight gain often results in large for gestational age babies also may increase risk during delivery. Good nutrition and a healthy diet during pregnancy are critical for a mother’s health, as well as that of her child. A healthy diet contains adequate energy, protein, vitamins and mineral obtained from a variety of foods including green and orange vegetables, meat, fish, beans, nuts, whole grains, and fruit. Many studies have suggested that weight gain during pregnancy is affected by prepregnancy BMI. This study is conducted to determine maternal weight gain, pattern and associated of some selected socio-demographic factors. Method: A cross-sectional analytic study wholly done from July 4th to December 20th; the sample size was 114 pregnant antenatal care files archived selected from primary health care centers. It searched for the full previous pregnancy files and with frequent visits from the beginning of pregnancy to birth. The data and information were collected from antenatal care files from six primary health care centers of As-Salam, AL-A’dil, AL-Mansour, AL-A’dhamiya 3rd, AL-Baladiyaat, AL-Mustansiriya. The exclusion criteria exclude all incomplete files, pregnant women less than 18 years, and pregnant with chronic disease multiple pregnancy. Frequencies and percentage were calculated; Chi square test were used; and the statistical probability were consider significant if P value < 0.05. Results: The current study was conducted through 114 pregnant care files or antenatal care in 6 primary health care centers. 73% of them gained excessive weight during pregnancy; 11% of them gained insufficient weight gain during pregnancy; and 17% of pregnant women had adequate weight gain during pregnancy. There was a statistically significant association between weight gain during pregnancy and primary health care centers, as representing social factor, and also significant association between pre pregnancy BMI and gestational weight gain. Conclusion: Gestational weight gain was significantly affected by pre pregnancy body mass index. Prevalence of excessive weight gain increases with the increase of the pre-pregnancy body mass index and with the increase of age in pregnant women. Weight gain during pregnancy should be monitored and intervention should be developed.

One-Step in Situ Synthesis of Tough and Highly Conductive Ionohydrogels with Water-Retentive and Antifreezing Properties

Flexible and conductive gels are promising materials as intelligent and wearable electronics. Herein, through a facile one-step in situ free-radical polymerization, tough VSNPs-PAA-Zr4+ ionohydrogels with integrated multiple functionalities are prepared, which are dually cross-linked by multivalent vinyl-functionalized silica nanoparticles (VSNPs) and metal coordination between Zr4+ and the carboxyl groups in PAA chains. The incorporation of Zr4+ with stable valency during polymerization enables the direct formation of a large number of metal coordination cross-links for adequate energy dissipation, overcoming the inhibition of unstable metal ions on the polymerization process. Meanwhile, VSNPs serve as multivalent cross-linkers and effective stress transfer centers. The obtained VSNPs-PAA-Zr4+ ionohydrogels show high toughness of up to 25 MJ m-3 with a high tensile strength of 3010 kPa and a large elongation at break of 1360%, along with reliable adhesive performance. Attributed to use of an IL/water binary solvent, the ionohydrogels possess excellent water-retentive and antifreezing abilities. Moreover, the existence of large quantities of mobile ions endows the VSNPs-PAA-Zr4+ ionohydrogels with a superior conductivity of 4.77 S m-1 and a high strain sensitivity with a gauge factor (GF) of 9.04, which are promising materials as intelligent and wearable strain sensors.

Ginsenoside Rg5 nanomedicine composited hydrogel with metabolic regulation and immunomodulation properties for tunneling diabetic wounds therapy

Diabetic wounds behaved delayed healing mainly due to impaired metabolism, dysregulated inflammation, and unique tunneling morphology. Herein, a customized nanocomposite hydrogel for diabetic wounds therapy was designed, demonstrating injectability, shape-adaptivity, and mechanical durability that adapt to the tunneling wound morphology. The hydrogel performed controlled drug release for metabolic regulation and immunomodulatory under topical administration. This hydrogel consists of oxidized anredera cordifolia polysaccharide (OACS), adipic dihydrazide grafted collagen fiber (CF-ADH), and ginsenoside Rg5 loaded polyethyleneimine grafted F127 nanoparticles (F127-PEI@Rg5 NPs). Triple dynamic bonds contributed to the fast cross-linking reconstitution during shape-remodeling, including the acylhydrazone and amine bonds formed from CF-ADH and F127-PEI@Rg5 NPs with OACS, and the electrostatic interactions between the inherent carboxyl groups and protonated amino groups in the materials. The nanolization and two-step loading of Rg5 leaded to improved bioavailability and prolonged drug action time. As a result, this hydrogel exhibited expected regulation for key enzymes in glycolysis, and relieved insulin resistance, thus providing an adequate energy supply for tissue remolding. Additionally, it increased macrophages number and promoted macrophages polarization, thus breaking the prolonged inflammation of diabetic wounds. In vivo experiments showed that the healing period was shortened by 34%, suggesting a promising dressing for diabetic wounds.

P29: Snore Vibro-acoustic Platelet Activation: A Thrombotic Risk Factor in Obstructive Sleep Apnea

Background: Obstructive sleep apnea (OSA) is a common disease state with prevalence in the U.S. of near 25%. of the population, characterized by snoring and apnea. Beyond intermittent hypoxemia, OSA imparts increased risk of myocardial infarction (MI) and stroke (CVA), both driven by thrombosis and thromboembolism. Central in thrombosis is platelet activation, traditionally felt to driven by biochemical agonists. We explored the possibility that mechanical vibration generated by OSA snore is also a driver of platelet activation. We hypothesized that OSA snore frequency components induce vibration capable of platelet activation. Here we characterized 1. the frequency content of OSA snore and 2. the effect of specific frequencies ranges on platelet activation, and 3. the optoacoustic vibration pattern generated by snore frequency components. Methods: Snore from OSA patients was recorded in a sleep lab. A snore emulator device (speaker platform) was constructed allowing exposure of human gel filtered platelets to snore via placement on a stage transmitting sound and associated vibration, at clinical sound intensity. Snore was analyzed as to sound frequency content. Gel filtered platelet were exposed to snore sound bandwidths (100 – 1000 Hz.) for 40 min (identical intensities) with activation assessed by thrombin generation (PAS assay). Snore vibration was characterized via assessment of optoacoustic fluid wave patterns generated. Results: OSA snore vibration led to definitive platelet activation. Notably, low frequency snore bandwidths induced greater degrees of activation than high frequency exposure - 53.26% activation at 300 hz vs. 13.44% at 900 hz. (Fig. 1a). Low frequency bandwidths induced noticeably greater fluid oscillation than high frequency bandwidth exposure. (Fig. 1b). Conclusion: OSA snore is capable of inducing vibrations which impart adequate mechanical energy to fluid to induce platelet activation. Within snore, specific frequency bandwidths, i.e. low frequencies, appear to be more activating than others. Correlating with platelet activation is detectable visual fluid disturbance which may be characterized via opto-acoustic patterns. Modulation of sound and vibration associated with OSA snore may offer opportunity as a means of limiting thrombotic consequences and adverse events associated with OSA.

Development and seismic behavior of an assembly composite damping self‐centering brace

AbstractA new type of assembly composite damping self‐centering brace is proposed to simplify the configuration, reduce the manufacturing cost, and improve its energy dissipation capacity, which is assembled by several modules in parallel with different functions. A brace specimen with a total length of 1.843 m was designed and numerically analyzed. The brace exhibits stable and full flag‐shaped hysteretic responses, and dissipates adequate energy during cyclic motion, with a high bearing capacity. When the brace is unloaded, the viscous damping force disappears, and the residual displacement can be basically eliminated. The hysteretic envelope area increases with the increase in loading frequency. When the frequency is 0.5 Hz and the target displacement is 30 mm, the activation force, ultimate bearing capacity, residual displacement, energy dissipation during one cycle, and equivalent viscous damping ratio are 622.5 kN, 1018.7 kN, 9.11 mm, 41.10 kJ, and 0.214, respectively. Under random loading, the damping force provided by the viscous module ensures a fuller hysteretic loop than the existing displacement‐type energy dissipation self‐centering brace. The influences of design parameters on the hysteretic performances of the brace were studied. When the disc spring stiffness increases from 3.27 to 9.80 kN/mm, the ultimate bearing capacity, residual displacement, and equivalent viscous damping ratio change by 18%, −24%, and −15%, respectively. The viscous damping coefficient and flow index of the viscous module should be increased, and the prepressed force and stiffness of disc springs in recentering module should also be appropriately increased.

Evaluation of the energy viability of smart IoT sensors using TinyML for computer vision applications: A case study

TinyML technology emerges from the intersection of Machine Learning, Embedded Systems, and Internet of Things (IoT), and presents itself as a solution for various IoT fields. For this technology to be successfully applied to embedded devices, it is essential that these devices have adequate energy efficiency. To demonstrate the viability of TinyML technology on embedded devices, field re- search and real experiments were conducted. An embedded system was installed in a turnstile of a Federal Institute, in which a TinyML computer vision model for people detection was implemented. The device counts the number of people, analyzes the battery level, and sends data in real-time to the cloud. The prototype showed promising results, and studies were conducted with a lithium battery and three in series. In these experiments, voltage consumption was analyzed every hour, and the results were presented through graphs. The camera sensor prototype had a consumption of 1.25 volts/hour, while the prototype without the camera sensor showed a longer-lasting consumption of 0.93 volts/hour. This field research will contribute to the advancement of applications and studies related to TinyML in conjunction with IoT and computer vision.
