Inspired by the photoelectric effect,a phototube is incorporated into a simple neural circuit,and then the output voltage and dynamics become sensitive to external illumination within a specific frequency band.The firing modes are also dependent on the amplitude and frequency band in the illumination.In this paper,the signal outputs from a chaotic circuit are used as external optical signals,which are filtered and encoded by a phototube.Then,the functional neural circuit is excited to present a variety of firing modes and patterns.An exponential function of the filtering wave is proposed to discover the biophysical mechanism for frequency selection in the retina as most of wave bands of the external illumination are absorbed in the cathode material of the phototube while a specific band is effective in inducing a photocurrent for stimulating the visual neurons.Based on our light-sensitive neural circuit and model,external illumination is filtered and firing modes in the neuron are reproduced;furthermore,the mode transition induced by parameter shift is also investigated in detail.This result discovers the signal processing mechanism in the visual neurons and provides helpful guidance for designing artificial sensors for encoding optical signals and for repairing abnormalities in the retina of the visual system. 展开更多

Gesture recognition technology enables machines to read human gestures and has significant application prospects in the fields of human-computer interaction and sign language translation.Existing researches usually use convolutional neural networks to extract features directly from raw gesture data for gesture recognition,but the networks are affected by much interference information in the input data and thus fit to some unimportant features.In this paper,we proposed a novel method for encoding spatio-temporal information,which can enhance the key features required for gesture recognition,such as shape,structure,contour,position and hand motion of gestures,thereby improving the accuracy of gesture recognition.This encoding method can encode arbitrarily multiple frames of gesture data into a single frame of the spatio-temporal feature map and use the spatio-temporal feature map as the input to the neural network.This can guide the model to fit important features while avoiding the use of complex recurrent network structures to extract temporal features.In addition,we designed two sub-networks and trained the model using a sub-network pre-training strategy that trains the sub-networks first and then the entire network,so as to avoid the subnetworks focusing too much on the information of a single category feature and being overly influenced by each other’s features.Experimental results on two public gesture datasets show that the proposed spatio-temporal information encoding method achieves advanced accuracy. 展开更多

The olfactory bulb(OB)is the first relay station in the olfactory system and functions as a crucial hub.It can represent odor information precisely and accurately in an ever-changing environment.As the only output neurons in the OB,mitralufted cells encode information such as odor identity and concentration.Recently,the neural strategies and mechanisms underlying odor representation and encoding in the OB have been investigated extensively.Here we review the main progress on this topic.We first review the neurons and circuits involved in odor representation,including the different cell types in the OB and the neural circuits within and beyond the OB.We will then discuss how two different coding strategies—spatial coding and temporal coding—work in the rodent OB.Finally,we discuss potential future directions for this research topic.Overall,this review provides a comprehensive description of our current understanding of how odor information is represented and encoded by mitralufted cells in the OB. 展开更多

Physicists possess an intuitive awareness of Euclidian space and time and Galilean transformation, and are then challenged with Minkowski space-time and Einstein’s curved space-time. Relativistic experiments support the “time-dilation” interpretation and others support “curved space-time” interpretation. In this, and related work, we investigate the key issues in terms of the intuitive space-time frame. In particular, we provide alternative approaches to explain “time dilation” and to explain the energy density for gravity systems. We approach the latter problem from an information perspective. 展开更多

Because the equivalence principle forbids local mass density, we cannot formulate general relativistic mass as an integral over mass density as in Newtonian gravity. This century-old problem was addressed forty years ago by Penrose, and many papers have since extended the concept. Currently there is no satisfactory physical understanding of the nature of quasi-local mass. In this paper I review the key issues, the current status, and propose an alternative interpretation of the problem of local mass and energy density for gravity systems from an information perspective. 展开更多

Metal nanomaterials have garnered significant attention due to their distinctive physical and chemical properties,which present promising applications in sensing,catalysis,and energy.However,chromium-based nanomaterials have been relatively overlooked in terms of their synthesis,properties,and applications.This research presents a rapid and efficient method for synthesizing chromium-based nanoparticles(Cr NPs)with tunable fluorescence capability to detect tumor-derived exosomes(TDEs)and implement information security at the molecular level.The synthesis process involved a straightforward procedure of mixing pre-cooled Cr6+ and NaBH4 solutions for 30 min.The resultant spherical Cr NPs displayed unique fluorescence modulation(including quenching or enhancing)for various dyes and DNA with different compositions.Leveraging these fluorescence characteristics,a CD63 aptamer-Cr NPs sensing system was constructed for detecting CD63-positive TDEs even in real samples while encoding and protecting information.In this system,fluorescence-labeled CD63 aptamers functioned as recognition probes and information carriers,forming a stego object by adsorbing onto the Cr NPs.The specific binding of the CD63 aptamer-Cr NPs to CD63 or TDEs elicited distinct fluorescence responses,thereby enabling precise quantitative detection alongside data encryption and protection.This study provides a new extension for the preparation and application of novel metal nanomaterials,offers a new platform for the rapid detection of tumor biomarkers,and opens up a direction for the integration of sensing and information science based on molecular systems. 展开更多

Ultrahigh-speed imaging is crucial for capturing transient phenomena across a wide range of scientific and industrial applications.Time-wavelength mapping-based high-speed imaging,which encodes temporal information into the spectral domain via optical modulation,has attracted significant interest.However,achieving both flexible time windows and high imaging fidelity remains challenging.To overcome this limitation,we propose an ultrahigh-speed imaging technique based on time-varying acousto-optic filtering(TAFUI).By modulating a broadband supercontinuum light source using an acousto-optic tunable filter driven by a time-varying radio frequency signal,TAFUI encodes the temporal evolution of dynamic scenes into the spectral domain with adaptable time windows.The spectrally encoded information is then captured by a hyperspectral camera and reconstructed into a temporal sequence through wavelength-time mapping,which attains high fidelity by minimizing spectral crosstalk.The technique achieves high-fidelity ultrahigh-speed imaging with a frame rate of 1.6 million frames per second,a spatial resolution of 724 lp/mm,and a sequence depth of 16.The imaging capability of TAFUI is demonstrated through experimental observations of the rotation of an optical chopper,the motion of microspheres in a microfluidic chip,and the morphological evolution of presheared water-in-oil droplets during transport.With its compact configuration,flexible time window adjustment,and high image fidelity,TAFUI serves as a powerful tool for high-resolution,real-time observation of complex ultrahigh-speed phenomena in scientific,engineering,and biomedical applications. 展开更多

Dear Editor,Transfer RNA(tRNA)is an indispensable adaptor molecule in the messenger RNA(mRNA)translation machinery,facilitating the conversion of genetic information encoded in mRNA into functional proteins.Numerous posttranscriptional modifications in tRNA have been identified,which play significantroles in modulating tRNA folding,biochemical stability,amino-acylation,and codon–anticodon interaction(Suzuki,2021).TRMT10A,the mammalian homolog of Trm10,incorporates N1-methylguanosine modification at position 9(m1G9)of various cytoplasmic tRNAs,including tRNAGln and tRNAIniMeth(Vilardo et al.,2020).Mutations in human TRMT10A,which is enriched in pancreatic islets and brain(Igoillo-Esteve et al.,2013),are often associated with microcephaly,intellectual disability,early-onset diabetes,and short stature(Igoillo-Esteve et al.,2013;Uçan Tokuçet al.,2024). 展开更多

Spin （polarization） is widely used in free-space optics, while in photouic integrated circuits （PICs）, infor- mation is usually encoded in optical route. So a practical way to connect these two encoding methods is necessary for information communication. In this letter, an encoding convertor is designed to connect spin encoding and route encoding. Finite element method is used to calculate the conversion efficiency and extinction ratio of the encoding convertor and the theoretical analyses are also given. Our protocol shows a friendly way to convert optical spin information to route information, which will promote the compatibility of free-space optics and PICs. 展开更多
