    Abstract Forgetting is an oft-forgotten art. Many artificial intelligence (AI) systems deliver good performance when first implemented; however, as the contextual environment changes, they become out of date and their performance degrades. Learning new knowledge is part of the solution, but forgetting outdated facts and information is a vital part of the process of renewal. However, forgetting proves to be a surprisingly difficult concept to either understand or implement. Much of AI is based on analogies with natural systems, and although all of us have plenty of experiences with having forgotten something, as yet we have only an incomplete picture of how this process occurs in the brain. A recent judgment by the European Court concerns the “right to be forgotten” by web index services such as Google. This has made debate and research into the concept of forgetting very urgent. Given the rapid growth in requests for pages to be forgotten, it is clear that the process will have to be automated and that intelligent systems of forgetting are required in order to meet this challenge.

    Abstract Objective: To report outcomes of a large cohort of patients who underwent endoscopic endonasal transsphenoidal surgery (EETS) for resection of a pituitary adenoma with subsequent Resorb-X plate (RXP) sellar reconstruction.
    Methods: A retrospective review of 620 EETS operations performed at a single academic center between 2005 and 2020 was conducted.
    Results: A total of 215 EETS operations of 208 patients were identified between 2012 and 2020 who underwent reconstruction with the RXP after EETS for pituitary tumor resection with a final pathologic diagnosis of pituitary adenoma. Analysis of pooled data revealed a mean preoperative tumor volume of 6.8 cm
    Conclusions: The rate of postoperative CSF leak and meningitis after use of the RXP for sellar reconstruction compares favorably to other methods, including use of autologous grafts and flaps. Use of RXP during EETS is a safe and efficacious method of sellar reconstruction and may obviate the need for autologous tissue reconstruction after pituitary adenoma resection.

    Abstract Intelligent systems are reaching the point where they can take very significant decisions on behalf of humans and society. The moral and ethical impact of such systems needs to be taken very seriously, both internally and externally in respect of such systems. Although some work into defining and systematizing machine ethics has begun, a great deal of work remains to be done and many research questions remain open.

    Abstract In this article intelligent systems are placed in the context of accelerated Turing machines. Although such machines are not currently a reality, the very real gains in computing power made over previous decades require us to continually reevaluate the potential of intelligent systems. The economic theories of Adam Smith provide us with a useful insight into this question.

    Abstract To promote the environmental sustainability of rural sanitation, a soil moisture controlled wastewater subsurface drip irrigation (SDI) dispersal system was field tested in the Black Belt Prairie of Alabama, USA. The soil moisture control strategy was designed to regulate wastewater disposal timing according to drain field conditions to prevent hydraulic overloading and corresponding environmental hazard. CW2D/HYDRUS simulation modeling was utilized to explore difficult-to-measure aspects of system performance. While the control system successfully adapted hydraulic loading rate to changing drain field conditions, saturated field conditions during the dormant season presented practical application challenges. The paired field experiment and simulation model demonstrate that soil biofilm growth was stimulated in the vicinity of drip emitters. Although biofilm growth is critical in maintaining adequate COD and NH4+−N removal efficiencies, the efficient removal of biodegradable COD itself by soil biofilm limits denitrification of formed NO3−−N . Furthermore, stimulated soil biofilm growth can create soil clogging around drip emitters, which was discerned in the field experiment along with salt accumulation, both of which were verified by simulation. Comparable modeling of system performance in sand and clay media demonstrate that the placement of soil moisture sensors within the drain field can have pronounced impacts on system hydraulic performance, depending on the soil permeability. Overall, the soil moisture control strategy tested is shown as a viable supplemental technology to promote the environmental sustainability of rural sanitation systems.

    Abstract Background: Gait impairment is an essential symptom of Parkinson's disease (PD).
    Objective: This paper introduces a novel computer-vision framework for automatic classification of the severity of gait impairment using front-view motion analysis.
    Methods: Four hundred and fifty-six videos were recorded from 19 PD patients using an RGB camera during clinical gait assessment. Gait performance in each video was rated by a neurologist using the unified Parkinson's disease rating scale for gait examination (UPDRS-gait). The proposed algorithm detects and tracks the silhouette of the test subject in the video to generate a height signal. Gait features were extracted from the height signal. Feature analysis was performed using the Kruskal-Wallis rank test. A support vector machine was trained using the features to classify the severity levels according to UPDRS-gait in 10-fold cross-validation.
    Results: Features significantly (p< 0.05) differentiated between median-ranks of UPDRS-gait levels. The SVM classified the levels with a promising area under the ROC of 80.88%.
    Conclusion: Findings support the feasibility of this model for Parkinson's gait assessment in the home environment.

    Abstract Objective: Radiation therapy is a mainstay in the treatment of numerous neoplasms. Numerous publications have reported good clinical outcomes for primary radiation therapy for Vestibular Schwannomas (VS). However, there are relatively few pathologic specimens of VSs available to evaluate post-radiation, which has led to a relative dearth in research on the cellular mechanisms underlying the effects of radiation therapy on VSs.
    Methods: Here we review the latest literature on the complex biological effects of radiation therapy on these benign tumors-including resistance to oxidative stress, mechanisms of DNA damage repair, alterations in normal growth factor pathways, changes in surrounding vasculature, and alterations in immune responses following radiation.
    Results: Although VSs are highly radioresistant, radiotherapy is often successful in arresting their growth.
    Conclusion: By better understanding the mechanisms underlying these effects, we could potentially harness such mechanisms in the future to potentiate the clinical effects of radiotherapy on VSs.

    Abstract Decentralized onsite wastewater treatment systems (OWTS) play an important role in alleviating the global carbon emissions pressure and meeting the United Nations Sustainable Development Goal for 2030. As a type of OWTS, intermittent sand filters (ISF) have a wide application in rural areas, but bioaccumulation caused bioclogging threatens its viability as a rural wastewater treatment technology. Proper understanding of the relationship between bioclogging and wastewater treatment is fundamental to the environmental sustainability of ISF. In this study, the interplay of ISF bioclogging and wastewater treatment efficiency is described by a mechanistic deterministic model to explore the role of bioclogging in ISF performance. The model incorporates variably saturated flows, reactive pollutant transport, bacterial growth, bioclogging caused soil permeability change, and reactive gas-phase oxygen transport and provides several insights regarding ISF operations. It is demonstrated that bioclogging as a result of wastewater treatment is necessary in maintaining adequate wastewater treatment efficiency. Bioclogging zone is the most active wastewater treatment region and the coupling between stimulated oxygen utilization rate and triggered oxygen replenishment rate is decisive in bioclogging development speed and effluent N profile. Overall, this study challenges the traditional negative viewpoint toward bioclogging, and the positive and negative aspects of bioclogging in ISF can be managed to promote the environmental sustainability of ISF.
