Non-operative management of rectal cancer: Highlighting the controversies

There remains much ambiguity on what non-operative management(NOM)of rectal cancer truly entails in terms of the methods to be adopted and the best algorithm to follow.This is clearly shown by the discordance between various national and international guidelines on NOM of rectal cancer.The main aim of the NOM strategy is organ preservation and avoiding unnecessary surgical in-tervention,which carries its own risk of morbidity.A highly specific and sensitive surveillance program must be devised to avoid patients undergoing unnecessary surgical interventions.In many studies,NOM,often interchangeably called the Watch and Wait strategy,has been shown as a promising treatment option when undertaken in the appropriate patient population,where a clinical complete res-ponse is achieved.However,there are no clear guidelines on patient selection for NOM along with the optimal method of surveillance.

Phase Two of the Integrative Monsoon Frontal Rainfall Experiment(IMFRE-II)over the Middle and Lower Reaches of the Yangtze River in 2020

Phase Two of the Integrative Monsoon Frontal Rainfall Experiment(IMFRE-II)was conducted over the middle and lower reaches of the Yangtze River during the period 16 June to 19 July 2020.This paper provides a brief overview of the IMFRE-II field campaign,including the multiple ground-based remote sensors,aircraft probes,and their corresponding measurements during the 2020 mei-yu period,as well as how to use these numerous datasets to answer scientific questions.The highlights of IMFRE-II are:(1)to the best of our knowledge,IMFRE-II is the first field campaign in China to use ground-based,airborne,and spaceborne platforms to conduct comprehensive observations over the middle and lower reaches of the Yangtze River;and(2)seven aircraft flights were successfully carried out,and the spectra of ice particles,cloud droplets,and raindrops at different altitudes were obtained.These in-situ measurements will provide a“cloud truth”to validate the ground-based and satellite-retrieved cloud and precipitation properties and quantitatively estimate their retrieval uncertainties.They are also crucial for the development of a warm(and/or cold)rain conceptual model in order to better understand the cloud-to-rain conversion and accretion processes in mei-yu precipitation events.Through an integrative analysis of ground-based,aircraft,and satellite observations and model simulations,we can significantly improve our cloud and precipitation retrieval algorithms,investigate the microphysical properties of cloud and precipitation,understand in-depth the formation and dissipation mechanisms of mei-yu frontal systems,and improve cloud microphysics parameterization schemes and model simulations.

Blind Source Separation based on Time-Frequency Morphological Characteristics for Rigid Acoustic Scattering by Underwater Objects

Separation of the components of rigid acoustic scattering by underwater objects is essential in obtaining the structural characteristics of such objects. To overcome the problem of rigid structures appearing to have the same spectral structure in the time domain, time-frequency Blind Source Separation （BSS） can be used in combination with image morphology to separate the rigid scattering components of different objects. Based on a highlight model, the separation of the rigid scattering structure of objects with time-frequency distribution is deduced. Using a morphological filter, different characteristics in a Wigner-Ville Distribution （WVD） observed for single auto term and cross terms can be simplified to remove any cross-term interference. By selecting time and frequency points of the auto terms signal, the accuracy of BSS can be improved. A simulation experimental has been used to analyze the feasibility of the new method, with changing the pulse width of the transmitted signal, the relative amplitude and the time delay parameter. And simulation results show that the new method can not only separate rigid scattering components, but can also separate the components when elastic scattering and rigid scattering exist at the same time. Experimental results confirm that the new method can be used in separating the rigid scattering structure of underwater objects.

Pit-and trench-forming osteoclasts:a distinction that matters

Osteoclasts（OCs）seeded on bone slices either drill round pits or dig long trenches.Whereas pits correspond to intermittent resorption,trenches correspond to continuous and faster resorption and require a distinct assembly of the resorption apparatus.It is unknown whether the distinction between pits and trenches has any biological relevance.Using OCs prepared from different blood donors,we found that female OCs achieved increased resorption mainly through pit formation,whereas male OCs did so through trench formation.Trench formation went along with high collagenolytic activity and high cathepsin K（CatK）expression,thereby allowing deeper demineralization.A specific CatK inhibitor abrogated the generation of trenches,while still allowing the generation of pits.OCs obtained from bone marrow were more prone to generate trenches than those obtained from blood.Scanning electron microscopy of bone surfaces eroded in vivo showed trenches and pits of similar size as those made by OCs in culture.We conclude that the distinction between trench-and pit-forming OCs is relevant to the differences among OCs from different skeletal sites,different individuals,including gender,and results from differences in colIagenolytic power.This indicates a biological relevance and highlights the importance of discriminating between pits and trenches when assessing resorption.

Design of a new kind of chemical experiment container with virtual reality fusion

Background At present,the teaching of experiments in primary and secondary schools is affected by cost and security factors.Existing research on virtual experiment platforms has alleviated these problems.However,the lack of real experimental equipment and use of a single channel to understand user intentions weaken these platforms operationally and degrade the naturalness of interactions.Methods To solve these problems,we propose an intelligent experimental container structure and a situational awareness algorithm,both of which are verified and applied to a chemical experiment involving virtual-real fusion.First,the acquired images are denoised in the visual channel using the maximum diffuse reflection chroma to remove overexposure.Second,container situational awareness is realized by segmenting the image liquid level and establishing a relation-fitting model.Then,strategies for constructing complete behaviors and making priority comparisons among behaviors are adopted for information complementarity and independence,respectively.A multichannel intentional understanding model and an inter-active paradigm that integrates vision,hearing,and touch are proposed.Results The experimental results show that the accuracy of the intelligent container situation awareness proposed in this paper reaches 99%,and the accuracy of the proposed intention understanding algorithm reaches 94.7%.The test shows that the intelligent experimental system based on the new interaction paradigm also has better performance and a more realistic sense of operation experience in terms of experimental efficiency.Conclusion The results indicate that the proposed experimental container and algorithm can achieve a natural level of human-computer interaction in a virtual chemical experiment platform,enhance the user′s sense of operation,and achieve high levels of user satisfaction.

Rescuing agroforestry as strategy for agriculture in Southern Brazil

Knowledge about agricultural ecosystems, as well as about ecological and social interactions that occur in an agricultural context, is essential to promote a balanced environment for production. Incorporating the forest landscape into farming systems has promoted the development of integrated production systems such as agroforestry. However, many aspects of the relationship between farming and the forest landscape have changed since the modernization of agriculture introduced by the Green Revolution. The objectives of this review are：（1） to contribute to the understanding of the changes in cultivation strategies and in the dynamics of agricultural systems,particularly in the context of farming in Santa Catarina State, Brazil;（2） to contribute to the understanding of agroforestry systems as a strategy to reintroduce the element of forestry into agricultural production systems; and（3） to compile a list of forest plant species that could be used in agroforestry. The approach adopted in this manuscript seeks to highlight the potential of agroforestry systems to conserve natural resources and thereby to support agricultural development by connecting environmental conservation with income for farmers.
