Market Turmoil Warning: Bitcoin Bulls on Alert as Spot vs. Perps Clash Raises Concerns

Recent analyses within the Bitcoin (BTC) market have unveiled compelling patterns, offering a deeper understanding of trading behaviors and market flows. Skew, a notable analyst, takes center stage in this exploration, shedding light on the nuanced interactions between the spot market and perpetual contracts (perps). The study provides insights into investor sentiment and potential shifts in market dynamics that could influence BTC prices.

In the spot market, a clear trend emerges, characterized by the prevalence of limit selling during price rebounds, particularly around the critical $50K mark. This observation is substantiated by spot order book data. Concurrently, price dips trigger a surge in taker buy volume, indicating a collective inclination to view these dips as opportune buying moments. Sustaining this buying behavior is pivotal for the continuity of bullish momentum, necessitating an upward trend in buy volume and active price pursuit by takers.

Contrastingly, the perpetual contracts market tells a different story. Escalating sell volume, combined with a noticeable lack of momentum or volatility, raises concerns about potential traps for short positions. This concern is exacerbated if not complemented by analogous spot selling. The divergence between spot and perps trading emphasizes the intricate dynamics at play, demanding careful analysis from market participants.

The examination of spot market flows across different platforms, such as Binance and Coinbase, introduces further complexity. Binance's ability to anticipate US session flows through front running stands in contrast to Coinbase's trading pattern, which involves a mix of time-weighted average price (TWAP) bids at the US market open and prevalent limit selling into the market.

The movement of funds into and out of Spot Exchange-Traded Funds (ETFs) like IBIT, FBTC, and GBTC plays a significant role in shaping market dynamics. These fund flows serve as a valuable barometer for investor sentiment and potential shifts in market direction, providing a nuanced view of the broader market landscape.

Comprehending the intricacies of BTC market flows necessitates a holistic perspective that considers both spot and derivatives markets, along with ETF movements. As the cryptocurrency market matures, these insights become indispensable for investors navigating the multifaceted and dynamic landscape of cryptocurrency trading.

Challenges in Cardiovascular Disease Management in Bangladesh

I. Introduction

Cardiovascular diseases, like heart disease and stroke, are a significant health challenge in Bangladesh. They require urgent attention due to their broad impact and potential consequences. The high prevalence of cardiovascular diseases in densely populated Bangladesh affects many people and strains healthcare resources, emphasizing the need for proactive measures.

II. Cardiovascular Disease in Bangladesh

In Bangladesh, CVD is a major health concern affecting a large portion of the population. These diseases encompass a range of heart and blood vessel-related conditions, including heart disease and strokes. The prevalence of cardiovascular diseases in the country is high, and they are a significant cause of illness and death. This not only takes a toll on the overall well-being of the population but also has a substantial impact on the healthcare system and the nation's economy. The burden of cardiovascular diseases in Bangladesh is not limited to any specific age group or socioeconomic status. People from various backgrounds can be affected, making it a pervasive issue. In addition to the individual suffering, the strain on healthcare resources and the cost of medical treatment are substantial. As a result, addressing the challenges associated with cardiovascular disease management in Bangladesh is of utmost importance to reduce the health and economic burden on the country.

III. Challenges in Prevention

Preventing cardiovascular diseases is a critical aspect of managing the burden they impose on Bangladesh. However, several challenges hinder these efforts. Firstly, there is a lack of awareness and health education about the risk factors and prevention strategies for heart disease. Many people do not know how their lifestyle choices, such as diet and physical activity, can impact their heart health. Secondly, limited access to preventive healthcare services is a significant obstacle. Not everyone in Bangladesh has easy access to regular check-ups and screenings, which are essential for early detection and prevention. Especially in rural areas, healthcare facilities may be scarce, making it challenging for people to receive the necessary information and services to protect their hearts. Thirdly, lifestyle factors, such as poor dietary habits and physical inactivity, contribute to the rising incidence of cardiovascular diseases in Bangladesh. Traditional diets high in salt and unhealthy fats, combined with a lack of exercise, increase the risk of developing heart problems. These challenges in prevention call for widespread educational campaigns, increased access to healthcare, and efforts to promote healthier living to address the root causes of cardiovascular diseases.

IV. Challenges in Diagnosis

Diagnosing cardiovascular diseases in Bangladesh poses a set of unique challenges. The healthcare infrastructure and resources available for diagnosis may be inadequate, particularly in rural areas. Access to specialized medical equipment and trained professionals is limited, which can result in delays and difficulties in identifying heart conditions. Moreover, there is a shortage of healthcare professionals with the specialized knowledge and skills needed to accurately diagnose cardiovascular diseases. Cardiologists and other specialists are often concentrated in urban areas, making it difficult for people in remote regions to access timely and appropriate care. Limited access to diagnostic tools and technology is another critical issue. Advanced diagnostic equipment like echocardiograms and angiography machines may not be readily available in all healthcare facilities. This can lead to patients having to travel long distances for necessary tests or facing prolonged waiting times, potentially exacerbating their conditions. Addressing these diagnostic challenges in Bangladesh involves improving healthcare infrastructure, increasing the number of trained professionals, and making advanced diagnostic tools more accessible across the country. Timely and accurate diagnosis is essential for effective management and treatment of cardiovascular diseases.

V. Challenges in Treatment

The treatment of cardiovascular diseases in Bangladesh encounters several hurdles, affecting the quality of care and outcomes for patients. Accessibility and affordability of cardiovascular treatments are significant issues. Many people, especially those from lower socioeconomic backgrounds, struggle to access the necessary medical interventions and medications. The cost of heart surgeries, stent placements, or long-term medication can be prohibitively expensive for a large segment of the population. Additionally, there is a shortage of specialized healthcare providers, particularly cardiologists and cardiac surgeons. The concentration of these experts in urban areas leaves residents of rural regions with limited access to specialist care. This can result in delayed treatment and poorer outcomes for patients. Furthermore, medication adherence and follow-up care present challenges. Some patients may find it challenging to adhere to a strict medication regimen, which is crucial for managing their heart conditions. Follow-up appointments and ongoing care can be difficult to maintain, particularly for those living in remote areas or with limited financial resources. Efforts to overcome these treatment challenges include measures to make cardiovascular treatments more affordable and accessible, increasing the number of specialized healthcare providers in rural areas, and implementing strategies to improve medication adherence and follow-up care. Addressing these issues is crucial to improving the management of cardiovascular diseases in Bangladesh.

VI. Conclusion

In summary, Challenges in Cardiovascular Disease Management in Bangladesh are out of the zone. Cardiovascular diseases, such as heart disease and stroke, present a critical health challenge in Bangladesh. These conditions affect a significant portion of the population and require immediate attention due to their far-reaching impact. The prevalence of these diseases places a strain on healthcare resources, emphasizing the need for proactive measures. Addressing this issue is vital not only for the well-being of the Bangladeshi people but also to ensure the sustainable functioning of the healthcare system. Therefore, exploring the causes, risk factors, and treatment options for cardiovascular diseases is essential, as it forms the foundation for effective interventions that contribute to the nation's development and the overall health of its citizens.

Overview of Vacuum Coating Materials And Technologies

Vacuum coating technology mainly involves the use of different vacuum coating equipment and process methods to generate coated materials on the surface of specific substrates in order to prepare a variety of thin film materials with specific functions. Application areas for vacuum coating technology include flat-panel displays, semiconductors, solar cells, magnetic and optical recording medias, optical components, energy saving glass, LEDs, tool modifications, high-end decorative items, etc. Thin film materials grow on top of substrate materials (such as screen glass, optical glass, etc.) and are generally formed by metal, non-metal, alloy or compound materials (collectively referred to as coating materials) after coating, and have the functions of increased transmission, absorption, cut-off, spectroscopy, reflection, light filtering, interference, protection, water and dirt repellency, anti-static, electrical conductivity, magnetic conductivity, insulation, abrasion resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, decoration and composite and other functions. Thin film materials can improve product quality, environmental protection, energy saving, extend the life of the product and improve the original performance, etc. As the thin film material is formed after the transfer of the coating material to the substrate, the quality of the film is directly related to the quality of the coating material. Currently, thin film material preparation technologies mainly include: physical vapour deposition (PVD) and chemical vapour deposition (CVD) technologies. Among them, physical vapour deposition (PVD) technology mainly includes vacuum sputtering coating, vacuum evaporation coating and vacuum ion coating.

Vacuum sputter coating. It refers to the technique of using ions generated by an ion source, which are accelerated and gathered in a vacuum to form a high ion beams, to bombard the surface of the target (coating material), where kinetic energy is exchanged between the ions and the atoms on the surface of the target, causing the atoms on the surface of the target to leave and be deposited on the surface of the substrate material. The object bombarded with ions is the raw material for the deposition of thin film materials by the vacuum sputtering method and is called a sputtering target.

Principle of vacuum sputtering coating

Generally speaking, sputtering targets are mainly composed of target blanks, back plates (or back tubes) and other parts, of which, target blanks are the target material bombarded by high-speed ion beams, belonging to the core part of sputtering targets. In the sputtering coating process, target blanks are hit by ions and its surface atoms are sputtered out and deposited on the substrate, making thin film materials. As the sputtering target needs to be installed in special equipment to complete the sputtering process, the equipment has a high voltage, high vacuum inner working environment and most of the target blank material is soft or highly brittle, not suitable for direct installation in the equipment, therefore, it need to be bound with the back plate (or back tube) which mainly plays a role as the fixator of sputtering target and has good electrical and thermal conductivity.

Characteristics of vacuum sputtered films:

Good controllability and repeatability of film thickness. The thickness of the film is controlled at a predetermined value, known as controllability of film thickness. The required film thickness can occur repeatedly, called film thickness repeatability. In vacuum sputter coating, the film thickness can be controlled by controlling the target current.

Strong adhesion of the film to the substrate. The energy of the sputtered atoms is 1-2 orders of magnitude higher than the energy of the evaporated atoms, and the energy conversion of the high-energy sputtered atoms deposited on the substrate is much higher than that of the evaporated atoms, generating higher energy and enhancing the adhesion of the sputtered atoms to the substrate.

In the preparation of alloy and compound films, the components of the target material are very close to that of the film material deposited onto the substrate, avoiding variation and inconsistency in the components and structure of the coating material as it is transferred to produce the film material.

New material films can also be prepared which are different from the target material. If a reactive gas is passed through the sputtering so that it reacts chemically with the target, a new material film which is completely different from the target can be obtained.

High purity of the film layer. The purity of the film is high. The sputtering method does not have the crucible component of the evaporation method, so the sputtering coating does not mix with the crucible heater material and has a higher purity. The disadvantages of the sputtering method are that the film formation speed is lower than that of evaporation, the substrate temperature is higher, it is more susceptible to impurity gases and the device structure is more complex.

Vacuum sputtering has become one of the mainstream technologies for the preparation of thin film materials due to the reproducibility and controllable thickness of the sputtering process, the ability to obtain uniform thickness films on large areas of substrate materials, the high purity of the films prepared, the good density and the strong bonding with the substrate materials. Various types of sputtering targets have been widely used, so the demand for sputtering targets, a functional material with high added value, is increasing at a high rate year by year, and sputtering targets have become the largest market application of PVD coating materials.

Vacuum evaporation coating. It is a deposition technique that uses the thermal energy of a film heating device (called an evaporation source) under vacuum conditions to deposit a substance on the surface of a substrate material by heating it to evaporate. When the mean free path of the evaporated molecules is larger than the dimension line between the evaporation source and the substrate, the evaporated particles escape from the surface of the evaporation source and are rarely hindered by the collision of other particles (mainly residual gas molecules) in the process of flying towards the surface of the substrate, and arrive directly at the surface of the substrate, condensing and producing a thin film. The evaporated material is the raw material for the deposition of thin film materials by vacuum evaporation coating and is called vapour deposition material.

Vacuum evaporation coating system generally consists of three components: the vacuum chamber, the evaporation source or evaporation heating unit, and the device for placing and heating the substrate. In order to evaporate the material to be deposited in a vacuum, a vessel is required to support or contain the evaporate and to provide evaporation heat to bring the evaporate to a high enough temperature to generate the required vapour pressure.

Principle of vacuum evaporation coating

Features of vacuum evaporation coating technology: simple equipment, easy operation, high purity and quality of the film made, accurate controllability of the thickness, fast filming rate , high efficiency, relatively simple growth mechanism of the film, etc.; the disadvantage are that it is not easy to obtain the film with crystalline structure; the adhesion of the film formed on the substrate is small; the repeatability of the process is not good enough, etc.

Vacuum ion coating. This refers to a process in which the film is evaporated or sputtered in a vacuum atmosphere, using an evaporation source or sputtering target, and part of the evaporated or sputtered particles are ionized into metal ions in the gas discharge space, and these particles are deposited onto the substrate under the action of an electric field to produce a thin film. The principle is shown in followed Figure. Firstly, the pressure of the coating chamber is evacuated to below 10-3pa, then the working gas is passed in to increase the pressure to 10^0~10^-1pa and the high pressure is accessed. As the cathode of the evaporation source grounded, the substrate is connected to the adjustable negative bias voltage, then the power supply can establish a low temperature plasma area with low pressure gas discharge between the evaporation source and the substrate, after the evaporation source of resistance heating type is energised and heats the film material, part of the neutral atoms escape from the surface of the film material and ionise into positive ions due to collision with electrons when passing through the plasma in the process of migration to the substrate; another part of the neutral atoms ions can also be generated by colliding with ions in the working gas and exchanging charges. These ions are then accelerated by the electric field and shot towards the substrate where they are connected to the negative potential, resulting in a thin film.

Principle of Vacuum Ion Coating

Characteristics of vacuum ion coating:

film/substrate adhesion is strong and the film layer is not easy to fall off;

ion plating has good diffraction, thus improving the coverage of the film layer;

high quality of the coating;

high deposition rate, film speed. 30 micron thick film can be prepared;

coating can be applied to a wide range of substrate materials and film materials.

Chemical Vapour Deposition (CVD). It is a filming technique that uses heating, plasma enhancement and light assist to make a solid film on the surface of a substrate by chemical reaction of gaseous substances under atmospheric or low pressure conditions.

Chemical vapour deposition CVD technology has the following characteristics:

the process and operation of the equipment is relatively simple and flexible, enabling the preparation of single or composite film layers and co-layers in various ratios;

the chemical vapour deposition CVD method is widely applicable;

the deposition rate can be as high as a few microns to hundreds of microns per minute, resulting in high production efficiency;

compared to the PVD method (vapour deposition, sputtering), it has good diffraction properties and is suitable for coating substrates with complex shapes;

good denseness of coating;

low damage after exposure to radiation and integration with the MOS integrated circuit (an integrated circuit consisting of metal-oxide-semiconductor field-effect transistors as the main components) process.

Summary: Vacuum coating technology mainly includes physical vapour deposition (PVD) technology and chemical vapour deposition (CVD) technology. The above mentioned vapour deposition, sputtering and ion deposition are all physical vapour deposition PVD, the basic principle of which can be summarised as follows: vapourisation of the plating material → migration of the atoms, molecules or ions in plating materials → deposition of atoms, molecules or ions in the plating materials on the substrate to recreate a thin film. Chemical vapour deposition CVD can be summarised as: formation of volatile substances → transfer of the substances to the deposition area → chemical reaction on the solid and production of a solid film substance.

SPECIALE CONGRESSO EUROPEO DI CARDIOLOGIA ESC 2023 Al Congresso europeo di cardiologia ESC 2023 di Amsterdam hanno partecipato più di trentamila operatori sanitari provenienti da 175 paesi, 24mila in presenza e 6.000 online. Tante notizie sono giunte da oltre 3750 abstract e casi clinici, presentati da scienziati provenienti da 86 paesi. La Germania è in testa con il maggior numero di abstract, seguita da Stati Uniti e Giappone. Circa 82 studi sono stati pubblicati contemporaneamente su riviste prestigiose. Tra le notizie più interessanti c’è l’analisi più completa dal 2006 sul costo delle malattie cardiovascolari (CVD) nell’Unione Europea. Il costo è di circa 282 miliardi di euro nel 2021, molto più dell’intero bilancio della stessa Unione Europea. Altra ricerca interessante ha riguardato chi soffre di diabete: i pazienti di tipo 2 hanno più del doppio delle probabilità di sviluppare malattie cardiovascolari (CVD) rispetto ai loro coetanei sani: un rischio da due a quattro volte più elevato di malattia coronarica, ictus, insufficienza cardiaca, fibrillazione atriale e malattia delle arterie periferiche rispetto a quelli senza diabete di tipo 2. Quando si verifica una malattia cardiovascolare, la prognosi è peggiore. Ad esempio, la mortalità dovuta a malattie cardiovascolari è maggiore del 50-90% nei pazienti con insufficienza cardiaca e diabete rispetto a quelli con sola insufficienza cardiaca. Altro tema affrontato è stato la necessità di maggiore attività fisica da bambini e adolescenti, poiché le ore di inattività durante l'infanzia potrebbero preparare il terreno per attacchi cardiaci e ictus più avanti nella vita. Lo studio ha rilevato che il tempo sedentario accumulato dall'infanzia alla prima età adulta è stato associati a danni cardiaci, anche in soggetti con peso e pressione sanguigna normali. Interessante anche uno studio che ha coinvolto tutti gli ospedali di Londra: non ha riscontrato differenze nella sopravvivenza a 30 giorni nei pazienti con arresto cardiaco rianimati, che sono stati portati in ambulanza in un centro per arresto cardiaco rispetto al pronto soccorso geograficamente più vicino. L’importante è intervenire subito sul paziente. Un altro studio, condotto su oltre 15.400 persone, ha rilevato che la forma fisica è collegata a una minore probabilità di sviluppare fibrillazione atriale e ictus. La fibrillazione atriale è il disturbo del ritmo cardiaco più comune e colpisce più di 40 milioni di persone in tutto il mondo. Si stima che un europeo su tre svilupperà la fibrillazione atriale nel corso della propria vita. I pazienti affetti da questa condizione hanno un rischio di ictus cinque volte maggiore rispetto ai loro coetanei. Nel corso del congresso di Amsterdam sono state presentate anche nuove linee guida, importanti per la pratica clinica in tutta Europa e non solo. Si tratta di quattro nuove linee guida, che coprono le sindromi coronariche acute, l’endocardite, le malattie cardiovascolari nel diabete e le cardiomiopatie, in questo caso la prima nel suo genere. Inoltre è stato presentato anche un aggiornamento mirato sulle Linee guida 2021 per l’insufficienza cardiaca. Un altro punto forte è stato il Digital Health Hub, con 37 sessioni sull'applicazione delle nuove tecnologie a tutte 3le sottospecialità della cardiologia.
