Functional near-infrared spectroscopy (fNIRS) is a non-invasive, low-cost method used to study the brain's blood flow pattern. Such patterns can enable us to classify performed by a subject. In recent research, most classification systems use traditional machine learning algorithms for the classification of tasks. These methods, which are easier to implement, usually suffer from low accuracy. Further, a complex pre-processing phase is required for data preparation before implementing traditional machine learning methods. The proposed system uses a Bi-Directional LSTM based deep learning architecture for task classification, including mental arithmetic, motor imagery, and idle state using fNIRS data. Further, this system will require less pre-processing than the traditional approach, saving time and computational resources while obtaining an accuracy of 81.48%, which is considerably higher than the accuracy obtained using conventional machine learning algorithms for the same data set.
功能性近红外光谱(fNIRS)是一种用于研究大脑血流模式的非侵入性、低成本方法。这样的模式可以使我们对一个主体的行为进行分类。在最近的研究中,大多数分类系统使用传统的机器学习算法对任务进行分类。这些方法虽然比较容易实现,但通常精度较低。此外,在实施传统的机器学习方法之前,数据准备需要一个复杂的预处理阶段。该系统使用基于双向LSTM的深度学习架构进行任务分类,包括心算、运动图像和使用fNIRS数据的空闲状态。此外,与传统方法相比,该系统需要更少的预处理,节省了时间和计算资源,同时获得了81.48%的准确率,大大高于使用传统机器学习算法获得的准确率。

In The common olfactory system odor recognition is processed by the electronic nose collecting sensor data, but the odor data collection of substances is easily affected by the environment and the processing is complicated, which is prone to deviation. This paper proposes a method based on big data analysis. According to the different chemical structure characteristics of different odor substances, the BP neural network is used to build a model to classify and recognize similar odors, and compare it with the traditional PCA+LDA recognition method. The results show that the establishment of a similar odor recognition model can accurately classify substances with similar odors, and the BP neural network algorithm is used to identify different substances with a higher rate of odor recognition. This method is stable and simple, and can provide different ideas for odor identification.

Social conventions governs our social behavior in many ways, ranging from left- and right-hand traffic to a way of greeting. We sometimes find inefficient social conventions like bullying in a class are formed, where almost of the people in the group are at a disadvantage. Although such conventions can be disadvantageous for all the people in the group, why are those conventions formed and continue to be maintained? A conformity bias, behavioral tendency with which people take an action that a majority of the group take, can be one of key ingredients of this phenomena. In this study, we investigated the impact of the conformity bias to the formation of social convention with a multi-agent simulations. Analysing stationary states of the dynamics of the model, we found that the conformity bias can drive the formation of both of efficient and inefficient social convention depending on an extent of the bias.
社会习俗在很多方面支配着我们的社会行为,从左右交通到打招呼的方式。我们有时会发现低效的社会习俗,比如在一个班级里形成欺凌,在这个群体中几乎所有的人都处于不利地位。虽然这样的惯例可能对群体中的所有人都不利,但为什么这些惯例会形成并继续保持?从众偏见,即人们采取群体中大多数人采取的行动的行为倾向,可能是这种现象的关键因素之一。在本研究中,我们通过多智能体模拟研究了从众偏见对社会习俗形成的影响。通过分析模型的静态动态,我们发现从众偏见可以驱动高效和低效社会习俗的形成,这取决于偏见的程度。

With the increasing use of ultrasonic ranging syste ms, their requirements are also increasing, requiring more accur ate measuring equipment. A design scheme of ultrasonic ranging system based on STM32 single chip microcomputer is proposed. Compared with the traditional SCM(single chip microcomputer), the main frequency and timer frequency of STM32 are as high a s 72 MHz, which improves the resolution of time measurement. When the timer is started, the PWM channel is started to drive the ultrasonic transmitter and the capture channel is input to cap ture the echo signal, which improves the measurement accuracy. On the basis of fully analyzing the blind area and error of ultrasonic ranging, the double operation amplifying circuit and band pass filtering circuit are designed, and the peak time of echo signal is detected by software algorithm, which simplifies the circuit. Experimental results show that the measurement accuracy of the system is high and the blind area is as low as 25mm.

In this paper, a high-precision Fast Fourier Transform algorithm is provided. Using the IP core provided in ISE, a software developed by Xilinx company, 16384 points of discrete data are calculated by Fast Fourier Transform. Using ISE, the simulation operation of FAST Fourier Transform of IEEE-754 floating point data and traditional fixed-point data was carried out, and the simulation results were compared and analyzed with those of MATLAB. In order to improve the precision of Fast Fourier Fransform, a comparative study is carried out from the aspects of operation time, resource consumption and precision. The simulation results show that the accuracy of IEEE-754 single precision floating-point simulation is significantly higher than that of fixed-point simulation. Therefore, IEEE 754 can greatly improve the operation accuracy of Fast Fourier Transform.

The increasing number of hospitalizations due to the ongoing pandemic has brought medical devices to the forefront of clinical management. For instance, mechanical ventilation is managed via administration of analgesia in combination with neuromuscular blocking agents, and hence, Neuromuscular Blockade Monitoring (NBM) devices are often needed in intensive care units. However, NBM devices are costly and, consequently, not widely available across low- and middle-income countries. Here, we present a prototype of an acceleromyography-based NBM device that we built using low-cost, over-the-counter, open-source software and hardware. Our prototype includes an accelerometer to record finger movement in response to electrical stimulation delivered by a TENS unit, and is able to detect muscle twitches in real-time to calculate and display metrics of the Train-of-Four (ToF) protocol used in clinics. Experimental measurements in a healthy subject suggest that our prototype can be used to quantify clinical variables in an apparently reliable manner, and so this prototype shows great promise in being able to transition into higher developing stages.
由于持续的大流行,住院人数不断增加,这使得医疗器械成为临床管理的前沿。例如,机械通气是通过镇痛与神经肌肉阻断剂联合使用来管理的,因此,在重症监护病房经常需要神经肌肉阻断监测(NBM)装置。然而,NBM设备价格昂贵,因此不能在低收入和中等收入国家广泛使用。在这里,我们展示了一个基于加速肌痛仪的NBM设备的原型,我们使用低成本,非处方药,开源软件和硬件。我们的原型包括一个加速计,用于记录手指对TENS单元发出的电刺激的反应,并能够实时检测肌肉抽搐,以计算和显示诊所使用的四人训练(ToF)协议的指标。对健康受试者的实验测量表明,我们的原型可以以一种明显可靠的方式用于量化临床变量,因此该原型在能够过渡到更高的发展阶段方面显示出很大的希望。
