Abstract:

This analytical study shows an interesting mechanism for the emission of THz radiation due to the production of an extra transverse component of the nonlinear ponderomotive force when an external periodic electric field is applied to a plasma having density ripples. Three components of the nonlinear ponderomotive force; one due to the beating of the incident lasers and two others due to the coupling of the external electric field with the incident lasers’ field are responsible for the generation of different nonlinear currents. These nonlinear currents excited at different resonances lea

Abstract:

The design of a magnetic pickup has a significant impact on the tone of an electric guitar. In particular, the magnetic force from the pickup can influence the string vibrations and cause a beating effect, depending on the strength of the magnetic force and the amplitude of the string vibrations. To understand this behavior, we performed experiments and simulations. We measured and modeled the transversal string restoring force at various displacements from the magnetic pickup in directions both parallel and perpendicular to the guitar body. We observed that the magnetic force distribution is

Abstract:

Shear stress at the cilia wall is considered as an imperative factor that affects the efficiency of cilia beatings as it describes the momentum transfer between the fluid and the cilia. We consider a visco-inelastic Prandtl fluid in a ciliated channel under electro-osmotic pumping and the slippage effect at cilia surface. Cilia beating is responsible for the stimulation of the flow in the channel. Evenly distributed cilia tend to move in a coordinated rhythm to mobilize propulsive metachronal waves along the channel surface by achieving elliptic trajectory movements in the flow direction.

AbstractThe nonlinear coupling of two high-power laser beams in plasmas in the presence of a transverse, static electric field is investigated to generate a difference frequency terahertz (THz) radiation. The relativistic variation of electron mass in the presence of two high-power laser beams is responsible for producing a nonlinear current driving the THz radiation. For typical laser and plasma parameters, we report the efficiency of the order of ~10−4 for the current scheme.

Abstract:

In the history of electrocardiography the names of two physiologists stand out: Augustus Waller (1865–1922) and Willem Einthoven (1860–1927). Waller was the first to show that the beating heart produces a weak electric potential, which can be registered by a measuring device connected to electrodes attached to the skin. Einthoven developed a 'string' galvanometer, which was much faster and more sensitive than the system used by Waller. Einthoven's electrocardiograph was ready for use in 1903. To facilitate investigations of patients Einthoven connected his instrument to the Academic Hospital i

Abstract:

Assessing animal welfare during handling for veterinary procedures or loading onto a truck is simpler than is assessing welfare in housing. The first step is preventing acts of abuse that everybody who is interested in animal welfare would want stopped. Acts of abuse include beating animals, poking sensitive areas, dragging downed animals, deliberate slamming of gates on animals or deliberate driving animals over the top of downed animals. The next step is to implement objective numerical scoring of animal handling. The outcome measures that should be used are percentage of animals that fall,

Smoking is one of the most basic needs in Indonesian society, in addition to primary and secondary needs. This can be seen from the data released from the Global Adult Tobacco Survey (GATS) 2021 as quoted by the Ministry of Health of the Republic of Indonesia found the fact that cigarettes are the second-largest spending requirement of Indonesian people with lower economic rates, beating spending on production for nutritious food. Not to mention that according to the data it is said that the average Indonesian population spends Rp. 382.091.7 per month only for the needs of cigarettes. Followin

Abstract:

Farming in areas with elephants has been the norm in many parts of Asia for thousands of years. In particular, farmers have settled closer to areas where elephants are present and started growing crops. Elephant raids occur in the night time where people do not notice the presence of an elephant until it starts an oﬀensive behavior. Such raids damage the crops, harvest storages and homes in addition to causing deaths of humans. A multitude of traditional methods have been developed through the ages to reduce and prevent crop raiding by elephants like shouting, drum-beating, noise-making, use o

Abstract:

The electrification of transportation is a growing strategy to reduce mobile source emissions and air pollution globally. To encourage adoption of electric vehicles, there is a need for reliable evidence about pricing in pub-lic charging stations that can serve a greater number of communities. However, user-entered pricing information by thousands of charge point operators (CPOs) has created ambiguity for large-scale aggregation, increasing both the cost of analysis for researchers and search costs for consumers.

Abstract:

In on-grid microgrids, electric vehicles (EVs) have to be efficiently scheduled for cost-effective electricity consumption and network operation. The stochastic nature of the involved parameters along with their large number and correlations make such scheduling a challenging task. This paper aims at identifying pertinent innovative solutions for reducing the relevant total costs of the on-grid EVs within hybrid microgrids. To optimally scale the EVs, a heuristic greedy approach is considered. Unlike most existing scheduling methodologies in the literature, the proposed greedy scheduler is mod

Abstract:

Cells in the cardiovascular system are permanently subjected to mechanical forces due to the pulsatile nature of blood flow and shear stress, created by the beating heart. These haemodynamic forces play an important role in the regulation of vascular development, remodelling, wound healing and atherosclerotic lesion formation. Mechanical stretch can modulate several different cellular functions in VSMCs (vascular smooth muscle cells). These functions include, but are not limited to, cell alignment and differentiation, migration, survival or apoptosis, vascular remodelling, and autocrine and pa

Abstract:

Ischaemic heart diseases are the leading causes of morbidity around the world and pose serious socio-economic burdens. Ischaemic events, such as myocardial infarction, lead to severe tissue damage and result in the formation of scar tissue. This scar tissue, being electrically inert, does not conduct electrical currents and thus generates lethal arrhythmias. The ventricle dilates with time due to asynchronous beating due to the scar, and it eventually leads to total heart failure. The current pharmacological approaches only cure heart failure symptoms without inducing tissue regeneration. Ther

Among these, the periodic beating sounds originating from flattened wheel treads attract most attention. As there is no sufficiently validated solution for wayside wheel flat detection which meets the requirements of precise detection, focus on acoustic relevance and economic feasibility, the German Federal Environmental Agency

Abstract:

Hodgkin and Huxley showed that even if the filaments are dissolved, a neuron’s membrane alone can generate and transmit the nerve spike. Regulating the time gap between spikes is the brain’s cognitive key. However, the time modula-tion mechanism is still a mystery. By inserting a coaxial probe deep inside a neuron, we have re-peatedly shown that the filaments transmit electromagnetic signals ~200 μs before an ionic nerve spike sets in. To understand its origin, here, we mapped the electromagnetic vortex produced by a filamentary bundle deep inside a neuron, regulating the nerve spike’s electri
