Abstract:

In this paper, we consider the evaluation of the mental attention state of individuals driving in a simulated environment. We tested a pool of subjects while driving on a highway and trying to overcome various obstacles placed along the course in both manual and autonomous driving scenarios. Most systems described in the literature use cameras to evaluate features such as blink rate and gaze direction. In this study, we instead analyse the subjects’ Electrodermal activity (EDA) Skin Potential Response (SPR), their Electrocardiogram (ECG), and their Electroencephalogram (EEG). From these signal

The assembly of microtubules during mitosis requires many identified components, such as γ-tubulin ring complex (γ-TuRC), components of the Ran pathway (e.g., TPX2, HuRP, and Rae1), and XMAP215/chTOG. However, it is far from clear how these factors function together or whether more factors exist. In this study, we used biochemistry to attempt to identify active microtubule nucleation protein complexes from Xenopus meiotic egg extracts. Unexpectedly, we found both microtubule assembly and bipolar spindle assembly required glycogen, which acted both as a crowding agent and as metabolic source gl

Abstract:

Early efforts in the 1980s showed that DNA microinjected intoXenopusembryos could be integrated into the genome and transmitted through the germline at low efficiency. Subsequent studies revealed that transgenic lines, typically with multiple-copy inserts (e.g., to develop bright fluorescent protein-reporter lines), could be created via sperm nuclear injection protocols such as the one entitled restriction enzyme-mediated insertion, or REMI. Here we describe a refined sperm nuclear injection procedure, with a number of alterations, including elimination of a potential DNA-damaging restriction

Abstract:

The purpose of this research was to produce the enriched eggs, but low in cholesterol content. Forty eight layer chickens aged 72 weeks (strain Dekalb Warren) were distributed into six treatment groups. One group of laying hens was fed diets without Sauropus androgynusleaf extract (SALE) as the control, and another five groups were fed diet supplemented to 9 g SALE, 18 g SALE, 27 g SALE, 36 g SALE, and 45 g SALE/kg diet, respectively. Completely randomized design was used in the present study.The experimental results showed that SALE supplementation had no effect on egg production, feed intake

Abstract:

Abstract Machine-learning techniques allow to extract information from electroencephalographic (EEG) recordings of brain activity. By processing the measurement results of a publicly available EEG dataset, we were able to obtain information that could be used to train a feedforward neural network to classify two types of volunteer activities with high efficiency.

Abstract:

Novel trends in affective computing are based on reliable sources of physiological signals such as Electroencephalogram (EEG), Electrocardiogram (ECG), and Galvanic Skin Response (GSR). The use of these signals provides challenges of performance improvement within a broader set of emotion classes in a less constrained real-world environment. To overcome these challenges, we propose a computational framework of 2D Convolutional Neural Network (CNN) architecture for the arrangement of 14 channels of EEG, and a combination of Long Short-Term Memory (LSTM) and 1D-CNN architecture for ECG and GSR.

Abstract:

Xenopus embryos initiate replication at random closely spaced sites until a certain concentration of nuclei is achieved within the embryo, after which fewer, more specific chromosomal sites are utilized as origins. We have examined the relationship between nucleo-cytosolic ratio and origin specification when Chinese hamster ovary (CHO) cell nuclei are introduced into Xenopus egg extracts. At concentrations of intact late-G1-phase nuclei that approximate early Xenopus embryos, the entire genome was duplicated nearly 4 times faster than in culture, accompanied by a de-localization of initiation

Abstract:

Nuclei assembled in Xenopus egg extract from purified DNA or chromatin resemble their natural counterparts in a number of structural and functional features. However, the most obvious structural element of normal interphase nuclei, the nucleolus, is absent from the in vitro reconstituted nuclei. By EM, cytological silver staining, and immunofluorescence microscopy employing antibodies directed against various nucleolar components we show that nuclei assembled in vitro contain numerous distinct aggregates that resemble prenucleolar bodies (PNBs) by several criteria. Formation of these PNB-like

Abstract:

When demembranated sperm nuclei are placed in a Xenopus egg extract, they become surrounded by a nuclear envelope and then swell to form morphologically typical pronuclei. Granules ranging from < 1.0 to approximately 3.0 microns in diameter appear within such nuclei. Bell et al. identified four nucleolar proteins in these "prenucleolar bodies" by immunofluorescent staining (fibrillarin, nucleolin, B23/NO38, 180-kDa nucleolar protein). By in situ hybridization we show that these bodies also contain U3 and U8 small nuclear RNAs (snRNAs), known to be involved in pre-rRNA processing. Moreover,

Abstract A new type of lamp holder based on brain-computer interface control is proposed, which makes the application of new technology in underground mining intelligent, including eye potential and myoelectricity generated when you blink. The extraction of brain wave shapes with different frequencies can reflect the state of the human brain. The current brain wave frequency mainly studied is between 0-100 Hz. The concrete method is to extract the original brainwave data by Fourier transform and wavelet transform. A double-threshold blink detection algorithm is designed, which can effectively
