Recently,discriminative machine learning models have been widely used to predict various attributes from Electron Backscatter Diffraction(EBSD)***,there has never been any generative model developed for EBSD pattern *** one hand,the training of generative models is much harder than that of discriminative ones;On the other hand,numerous variables affecting EBSD pattern formation make the input space high-dimensional and its relationship with the distribution of backscattered electrons *** this study,we propose a framework(EBSD-CVAE/GAN)with great flexibility and scalability to realize parametric simulation of EBSD *** with the frequently used forward model,EBSD-CVAE/GAN can take variables more than just orientation and generate corresponding EBSD patterns in a single *** accuracy and quality of generated patterns are systematically *** model does not only summarize a distribution of backscattered electrons at a higher level,but also mitigates data scarcity in this field.

The LSD (Logic for Structure Determination) program generates organicmolecular structures from 1D and 2D NMR data without resorting to chemical shift databases. Its usein the resolution of natural product structure determination problems has been already reported inthe literature. This paper describes how data and structures are internally represented andprocessed by LSD to build solution structures.

Pollutant dynamics and bioavailability greatly differ in soil and aquatic systems. Therefore, specific approaches and models are needed to assess the impact of soil contamination to terrestrial ecosystems. Earthworms among other soil invertebrates have received more attention because of their ecological importance. They represent a dominant part of the soil biomass and are soil engineers regulating important soil processes, notably fertilization. The release in soils of pollutants known for their persistence and/or their toxicity is a concern. Exposure of terrestrial species to pollutants that may alter genomic function has become an increasing topic of research in the last decade. Indeed, genome disturbances due to genetic and epigenetic mechanisms may impair growth, as well as reproduction and population dynamics in the long term. Despite their importance in gene expres- sion, epigenetic mechanisms are not yet understood in soil invertebrates. Until now, pollutant-induced changes in genome expression in natural biota are still being studied through structural alteration of DNA. The first biomarker relating to genotoxicant exposure in earthworms from multi-contaminated soils reported is DNA adducts measurements. It has been replaced by DNA breakage measured by the Comet assay, now more commonly used. Functional genomic changes are now being explored owing to molecular ＂omic＂ technologies. Approaches, objectives and results are overviewed herein. The focus is on studies dealing with genotoxicity and populational effects established from environmentally-relevant experiments and in situ studies [Current Zoology 60 （2）： 255-272, 2014].

Introduction: Palatal abscess or cellulitis of dental origin is a rare clinical form of circumscribed cellulitis that can sometimes pose a diagnostic problem. It is the consequence of poor or non-treatment of dental caries or trauma. The aim of this study is to describe the clinical and therapeutic aspects of these two cases of palatal cellulitis of post-traumatic dental origin. Observation: The patients consulted for painful palatal swelling secondary to untreated dental trauma of the 21s. The diagnosis of palatal cellulitis was based on the inflammatory and fluctuating nature of the swelling. A probabilistic bi-antibiotic treatment and an incision and drainage associated with treatment of the portal of entry were carried out. Progression was favourable in both cases. Conclusion: Palatal cellulitis is a rare condition and can be prevented by systematic stomatological consultation after dental trauma. Diagnosis is clinical. However, CT scans are sometimes useful. The course is generally favorable with appropriate treatment.

Objective: Postoperative pain (POP) following abdominal surgery can vary from a few hours to several days. This acute, unrelieved pain can become chronic, requiring patients to take analgesics on an almost daily basis for comfort. Analgesia using general opioids has many side effects and intrathecal morphine is a good alternative. This study was conducted to evaluate the efficacy of intrathecal morphine (ITM) versus conventional analgesia in the management of postoperative pain in colectomy performed by laparoscopic surgery. Methods: Cohort study conducted at the Hôpital Nord in Marseille, from 01 January to 31 July 2021 in patients aged at least 18 years undergoing anaesthesia for scheduled colectomy by laparoscopic surgery. The primary endpoint was postoperative pain intensity and the secondary endpoints were morphine consumption, treatment side effects and length of hospital stay. Statistical analysis was performed using XLSTAT software. Results: We included 193 patients: 131 in the control group (conventional analgesia) and 62 in the ITM group. We observed: a significant decrease in pain (assessed by numerical scale) in favour of the ITM group in the post-anaesthetic care room, i.e. 3 (±4) vs 1 (±2), p 0 and H2: 2 (±2) vs. 1 (±2);p Conclusion: These results suggest that intrathecal morphine (ITM) in laparoscopic colectomy provides effective postoperative analgesia with low morphine consumption, and a reduction in morphine side-effects compared with conventional analgesia.
