Speech emotion recognition(SER) is the use of speech signals to estimate the state of emotion. At present, machine learning is one of the main research methods of SER, the test and training data S of traditional machine learning all have the same distribution and feature space, but the data of speech is accessed from different environments and devices, with different distribution characteristics in real life. Thus, the traditional machine learning method is applied to the poor performance of SER. This paper proposes a multi-distributed SER method based on Mel frequency cepstogram(MFCC) and parameter transfer. The method is based on single-layer long short-term memory(LSTM), pre-trained inceptionv3 network and multi-distribution corpus. The speech pre-processed MFCC is taken as the input of single-layer LSTM, and input to the pre-trained inception-v3 *** features are extracted through the pre-trained inception-v3 model. Then the features are sent to the newly defined the fully connected layer and classification layer,let the parameters of the fully connected layer be finetuned, finally get the classification result. The experiment proves that the method can effectively complete the classification of multi-distribution speech emotions and is more effective than the traditional machine learning framework of SER.

Spinal cord injuries lead to significant loss of motor, sensory, and autonomic functions, presenting major challenges in neural regeneration. Achieving effective therapeutic concentrations at injury sites has been a slow process, partly due to the difficulty of delivering drugs effectively. Nanoparticles, with their targeted delivery capabilities, biocompatibility, and enhanced bioavailability over conventional drugs, are garnering attention for spinal cord injury treatment. This review explores the current mechanisms and shortcomings of existing treatments, highlighting the benefits and progress of nanoparticle-based approaches. We detail nanoparticle delivery methods for spinal cord injury, including local and intravenous injections, oral delivery, and biomaterial-assisted implantation, alongside strategies such as drug loading and surface modification. The discussion extends to how nanoparticles aid in reducing oxidative stress, dampening inflammation, fostering neural regeneration, and promoting angiogenesis. We summarize the use of various types of nanoparticles for treating spinal cord injuries, including metallic, polymeric, protein-based, inorganic non-metallic, and lipid nanoparticles. We also discuss the challenges faced, such as biosafety, effectiveness in humans, precise dosage control, standardization of production and characterization, immune responses, and targeted delivery in vivo. Additionally, we explore future directions, such as improving biosafety, standardizing manufacturing and characterization processes, and advancing human trials. Nanoparticles have shown considerable progress in targeted delivery and enhancing treatment efficacy for spinal cord injuries, presenting significant potential for clinical use and drug development.

Domoic acid (DA) is a neuroexcitatory amino acid that is produced by Pseudo-nitzschia during harmful algal blooms (HAB). Accumulation of DA can be transferred through food chain and cause neuronal damage in marine animal and in human. Like other algal toxins, DA was suggested to increase the oxidative stress and increase the detoxification-related gene expression in fish. The widely used food antioxidant, tert-butylhydroquinone (tBHQ), was known to induce a wide range of antioxidative potentials such as elevation of the glutathione levels and glutathione S-transferases (GSTs), via the activation of antioxidant response elements (AREs). In this study, the influences of dietary tBHQ on domoic acid (DA) metabolism and detoxification-related gene transcription were investigated both in vivo and in vitro. Oral administration of tBHQ resulted in significant decreases of DA accumulation of liver tissues in which red sea bream were fed with a single dose of 10 mg DA and 100 mg tBHQ per kg body weight per fish. Real-time PCR further revealed that the mRNA levels of AHR/ARNT/CYP1A1/GSTA1/GSTR were up-regulated in the above liver tissues at 72 h post tBHQ treatment. In consistence, tBHQ exposure also resulted in increased mRNA transcription of GSTA1, GSTA2 and GSTR in cultured red sea bream hepatocytes. Collectively, our findings in this research suggested that the dietary intake of tBHQ accelerated DA metabolism in fish, through mechanisms involving altered transcription of detoxification- related liver genes.

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.

植物甾醇的分子结构与胆固醇相似,作为膜结构调节剂,植物甾醇既能调节脂质体膜的结构性质,又能避免胆固醇摄入的负面影响。本研究以植物甾醇替代胆固醇,通过薄膜分散-超声法制备桑椹花色苷脂质体,评价了脂质体的包封率、粒径、电位和微观形态等指标,并探究了植物甾醇对脂质体pH稳定性和抗氧化活性的影响。结果表明,与胆固醇脂质体类似,植物甾醇的添加也能够得到粒径小、分散性好、包封率高的桑椹花色苷脂质体。当β-谷甾醇添加量为卵磷脂质量的26%时,桑椹花色苷脂质体贮藏后的DPPH自由基清除能力提高率是添加了等量胆固醇的脂质体的1.6倍。植物甾醇脂质体贮藏前后的氧自由基吸收能力(oxygen radical absorbance capacity,ORAC)优于胆固醇脂质体的,尤其在胆固醇脂质体贮藏后,ORAC值下降2.42倍~3.65倍,植物混合甾醇脂质体的ORAC值则变化不大。综上,采用植物甾醇替代胆固醇制备桑椹花色苷脂质体,可制得较稳定、并具有良好抗氧化活性的脂质体,可为负载生物活性物质的植物甾醇脂质体的构建提供理论基础。
