What is the reaction and function of the brain's neurons when people are calculating?
Past studies had found that there were neurons in the monkey's brain that were specifically used to calculate rules, but the human brain had previously lacked relevant data in this regard. Later, a research team tested the activity of nine patients with epilepsy (four men, average age 43.3 years) by inserting micro-electrons into the MTL (hippocampi and its cerebral) area of the brain and asking the volunteers to do addition and substitution. The volunteers sat on the bed, facing a touch-screen laptop about 50 centimeters away. The screen displayed numbers (or dots) and symbols in turn. The volunteers selected the calculation results from the digital keyboard, and the computer displayed right or wrong. The interval between each display was 800 ms. Each subject had a total of 320 experiments divided into 4 groups. The first 10 were rehearsals and were not included in the analysis. The researchers recorded the action potentials of 585 individual neurons in the MTL region, including 126 neurons in the parahippocampal-like cerebral cortexes, 199 neurons in the hippocampal-like cortexes, 107 neurons in the entorhinal cortexes, and 153 neurons in the almond nucleus. They then entered the action patterns into a self-learning computer program. Rule-selective neurons were determined based on multi-factor analysis of variation. These neurons would selectively increase their discharge after the calculation instruction (addition or deduction) was issued. For example, in the case of addition rules, the addition neurons showed specific activity, and the deduction neurons also showed specific activity under the deduction instruction. Moreover, the proportion of such selective neurons was different in different task cycles and MTL regions. At the same time, the code of calculation rules had nothing to do with the rule prompt. In the parahippocampal-like cerebral region, different addition neurons were active in the same arithmetic task. In addition, scientists found that the brain could produce quantum entanglement, which may be related to the high-speed operation of the human brain. Consciousness may be able to continue independently from the human body, but the specific connection between this discovery and the calculation of neurons was not clear. There were also studies that showed that when people focused on calculations, their neurons would become very active. When they were absent-minded and their minds were empty, their neurons would lack connections and their learning ability would be poor. This might also indirectly affect the performance of their neurons during calculations. Read more exciting novels for free

What is the principle of calculating the bearing reaction force in structural mechanics?
The principle of calculating the reaction force of the support in structural mechanics is based on the principle of force equilibrium. First of all, he had to determine the force on the object, including gravity, external force, etc. He could use the free-body diagram to represent the force point and direction. Then, the force balance of the object was calculated along the horizontal and vertical directions. For the balance of force in the horizontal direction, the reaction force in the horizontal direction is usually zero or equal to the external force in the horizontal direction; for the balance of force in the vertical direction, the reaction force in the vertical direction is usually equal to the gravity of the object or equal to the external force in the vertical direction. The calculation formula of the bearing reaction mainly included the equilibrium equation and the moment equation. The equilibrium equation states that when an object is in a state of static equilibrium, the resulting force and moment of all forces acting on the object are zero. In the calculation of the reaction force of the support, the equilibrium equation of the object was usually divided into two equations in the horizontal direction (where the sum of all the forces acting on the object in the horizontal direction was zero) and the vertical direction (where the sum of the forces in each direction was set to zero and the equation system was solved, the magnitude of the reaction force of the support could be solved. In addition, according to the type of support (such as fixed support, hinged support, etc.), the shape of the object, the way the force is applied, and other factors, the specific calculation method will be different. Complex force situations may require more complicated mechanical methods to calculate. For some special beam structures, there were some simple calculation methods. For example, for a simply supported beam under symmetrical load, the support reaction force could be divided into half by the symmetrical load, that is, the two supports each bear half of the load. For a simply supported beam under a biased load, the support reaction force could be calculated by the inverse ratio of the biased load. The support reaction force at one end of the beam was equal to the ratio of the distance from the point of action of the load to the other support and the length of the beam span multiplied by the size of the load. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Calculating the Bearing Reaction Force with the Equilibrium-equation of Theoretic Mechanics
In theoretical mechanics, when calculating the reaction force of a support in a plane force system: - ** Plane Convergence Force System **: The lines of action of all forces are in the same plane and converge at the same point. The equilibrium equations were as follows: ? Fx = 0 (the projection algebra sum of the x-direction force is zero) and? Fy = 0 (the projection algebra sum of the y-direction force is zero). - ** Plane arbitrary force system **: The lines of action of all forces are in the same plane and do not need to converge at the same point. The equilibrium equations were as follows: <anno data-annotation-id ="0fd11000 - 4c65 - 4c50 - 4c50 - 9c6c9999999"> Fx = 0 </anno>,</anno> Fy = 0, and <anno> Mo = 0 (the force system's moment algebra sum for any point O in the plane is zero). For the space force system, when calculating the reaction force of the support: - ** Space Convergence Force System **: The lines of action of all forces converge at the same point. The equilibrium equations were as follows: ? Fx = 0,? Fy = 0, and? Fz = 0 (the projection algebra sum of the forces in the x, y, and z directions is zero). - [Spatial Force System: No need to converge at the same point.] The equilibrium equations were as follows: ? Fx = 0,? Fy = 0,? Fz = 0,? Mx = 0 (the sum of the moments on the x axis is zero),? My = 0 (the sum of the moments on the y axis is zero), and? Mz = 0 (the sum of the moments on the z axis is zero). The usual steps to find the reaction force of the support were: first, take the separated body (separate the component that needs to find the reaction force of the support from the overall structure), then draw the force analysis diagram (accurately draw all the forces acting on the separated body, including the active force and the reaction force of the support), find the component with the simplest force (to determine the situation where the number of unknown forces is small), and finally calculate the reaction force of the support with the equilibrium equation. For example, for a simply supported beam, the support reaction force can be calculated by using the vertical direction, where the sum of the vertical force is zero. For the hinged point, the support reaction force can be calculated by using the sum of the moment of the hinged point. For hyperstatic structures (such as continuous beams, rigid frames, etc.), the force method or displacement method is needed to calculate. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Calculating the Conversion Rate of the First Stage Reaction in the Batch-type Reactors
对于间歇反应器中的一级反应，转化率与反应时间之间存在特定的关系。 设反应速率常数为\(k\)，反应时间为\(t\)，初始浓度为\(C_{A0}\)，\(t\)时刻的浓度为\(C_{A}\)，一级反应的速率方程为\(-\frac{dC_{A}}{dt}=kC_{A}\)，对其进行积分可得\(\ln\frac{C_{A}}{C_{A0}}=-kt\)，转化率\(x = \frac{C_{A0}-C_{A}}{C_{A0}}\)，则\(C_{A}=C_{A0}(1 - x)\)，将其代入前面的积分式可得\(\ln(1 - x)=-kt\)。 例如，已知反应时间为\(1h\)转化率为\(0.8\)，根据\(\ln(1 - x)=-kt\)，可求出\(k = -\frac{\ln(1 - 0.8)}{1}\)。若要求反应时间为\(2h\)的转化率，将\(t = 2\)和求出的\(k\)值代入\(\ln(1 - x)=-kt\)，可得\(\ln(1 - x)=-2\times(-\frac{\ln(1 - 0.8)}{1})\)，解出\(x\)的值;同理可求反应时间为\(0.5h\)的转化率。 具体的计算需要根据给定的条件，先求出反应速率常数\(k\)，再根据\(\ln(1 - x)=-kt\)求出不同反应时间下的转化率。 <a href="/?from=ask_words" style="color:red" target="_blank">点击前往免费阅读更多精彩小说</a>

What are the symptoms of motor neurons disease?
The symptoms of motor neurons disease included muscle weakness, muscle wasting, muscle bundle tremor, muscle spasms, increased muscle tone, tendon hyperreflexes, unclear speech, difficulty swallowing, tongue muscle wasting, difficulty breathing, and so on. The symptoms usually started from the upper limbs and gradually spread to other parts of the body. Early symptoms may be clumsy hand movements, tremors, lower limbs prone to tripping, speech stuttering, and painful tonus spasms. Late symptoms may involve the spinal cord and pontine nerve motor nucleus, resulting in tongue muscle atrophy, difficulty swallowing, and slurred speech, as well as affecting the head lifting muscle strength and respiratory muscles. Different types of MCD may have different symptoms.
