Deep neural network has proven to be very effective in computer vision *** convolutional network can learn the most suitable features of certain images without specific measure functions and outperform lots of traditional image processing *** adversarial network(GAN)is becoming one of the highlights among these deep neural *** is capable of generating realistic images which are imperceptible to the human vision system so that the generated images can be directly used as intermediate medium for many *** promising application of using GAN generated images would be image concealing which requires the embedded image looks like not being tampered to human vision system and also undetectable to most *** synthesizing has drawn lots of attention in computer vision field and is used for image concealing in steganography and *** traditional methods which use synthesized textures for information hiding mainly select features and mathematic functions by human metrics and usually have a low embedding *** paper takes advantage of the generative network and proposes an approach for synthesizing complex texture-like image of arbitrary size using a modified deep convolutional generative adversarial network(DCGAN),and then demonstrates the feasibility of embedding another image inside the generated texture while the difference between the two images is nearly invisible to the human eyes.

Grasping Heaven and Earth(Qian Kun Zai Wo):The Body-as-Technology in Classical Chinese Medicine

作者： marta Hanson Independent Scholar Affiliate Max Planck Institute for the History of ScienceBerlin 14195Germany

Shifting focus from the patient’s body to the healer’s body,this essay focuses on how Chinese physicians instrumentalized their bodies to heal(ie,body-as-technology)and their hands to think with(ie,hand-memory techniques or simply,hand mnemonics).When physicians used their hands to memorize concepts related to clinical practice,calculate with time variables,and carry out ritual gestures intended to reduce risk,improve fortune,and even cure,their hands became extensions of their *** essay has three parts that follow the discovery process of the author’s research on hand-memory techniques found in Chinese medical *** first part“Divination and Revelation”explains the significance of how the author first learned about Chinese divination practices that used hand *** second part“Original Frame”introduces the scholarship on arts of memory in Europe that informed interpretations of the earliest hand mnemonics found in Chinese medical *** third part“Expanded Frame”deploys some concepts from cognitive science to help situate Chinese medical hand mnemonics more broadly as an example of extended *** essay concludes with an important distinction:sometimes Chinese healers’hands were used separately from their bodies to think through things and sometimes hand and body had to be integrated in order for the healer’s body-as-technology to act as a therapeutically effective instrument.

Determinants of timing and amplitude in the plant general stress response

引用

Journal of Integrative Plant Biology 2016年第2期58卷 119-126页

作者： marta Bjornson Abhaya Dandekar Katayoon Dehesh Department of Plant Sciences University of California Department of Plant Biology University of California

Plants have evolved intricate signaling cascades to rapidly and effectively respond to biotic and abiotic challenges. The precise timing of these responses enables optimal resource reallocation to maintain the balance between stress adaptation and growth. Thus, an in-depth understanding of the immediate and long-term mechanisms regulating resource allocation is critical in deciphering how plants withstand environmental challenges. To date however, understanding of this tradeoff has focused on the amplitude of long-term responses, rather than the timing of rapid stress responses. This review presents current knowledge on kinetics of secondary messengers involved in regulation of rapid and general stress responses, followed by rapid stress responsive transduction machinery, and finally the transcriptional response of a functional general stress responsive cis-element. Within this context we discuss the role of timing of initial peak activation and later oscillating peak responses, and explore hormonal and stress signaling crosstalk confounding greater understanding of these cascades.

Gut-brain axis in traumatic brain injury: impact on neuroinflammation

Neural Regeneration Research 2022年第5期17卷 1007-1008页

作者： marta Celorrio Stuart H.Friess Division of Critical Care Medicine Department of PediatricsWashington University in St.Louis School of MedicineSt.LouisMOUSA Perspective

The gastrointestinal track is inhabited by tens of trillions of microorganisms. The gut microbiota is involved in gut motility, nutrient absorption and synthesis of metabolites that influence hmeostasis, metabolism and immunefunction. Given the influence gut microbiota has on health, there is a growing body of literature describing the gut microbiota's impact on brain and behavior.

The effect of Tyrophagus putrescentiae on Fusarium poae transmission and fungal community in stored barley in a laboratory experiment

引用

Insect Science 2014年第1期21卷 65-73页

作者： Jan Hubert marta Nesvorna Jan Kopecky Crop Research Institute Praha 6 Czech Repubfic

The effect of Tyrophagus putrescentiae on Fusarium poae transmission and fungal community composition was studied in nonsterile barley grain. The experiments included following treatments： control barley without mites; barley containing l0 or 50 mites without preincubation on E poae （Tpl0 and TpS0）; barley containing 10 or 50 mites after preincubation on E poae （FTp 10 and FTp50）. The number of mites, suc cessful transfer of E poae, and changes in the fungal communities were examined after 21 d of experiment. Increase of deoxynivalenol （DON） content in the barley was chosen as a criterion of successful Epoae transfer. The preincubation of T. putrescentiae on Epoae increased DON level approximately to 800 and 300μg/kg of grain for FTpl0 and FTpS0, respectively. T. putrescentiae population growth in FTpl0 was lower than in Tpl0, while no difference was found between FTp50 and Tp50. Fungal communities were compared by amplification, cloning and sequencing of ITS fragments, and operational taxonomic units （OTU） analysis. The OTU analysis did not support the transfer ofF. poae via mites. From the analyzed clones, only 13 cloned sequences clustered with E poae in an OTU defined at distance level 0.07. The related clones originated from FTpl0, Tpl 0, Tp50 and control treatments, but not from FTp50. However, the presence of E poae in FTp50 was confirmed by PCR amplification with specific primers. The observation may be explained by different effect of mite population density, that is, in the high density, （FTp50 treatment） the fungus was overgrazed, while the lower population density （FTp 10） supported E poae transfer.
