Particle concentration, charge, solution chemistry (i.e. ionic strength), and the nature of organic matter (OM) are the major factors controlling particle flocculation in aqueous environments. In the present study, the nature of clay fabric associated with clay—OM interaction at a range of ionic strengths was the focus. In the flocculation experiments, the aqueous suspension of montmorillonite and chitin was mixed with NaCl/MgSO4 electrolyte solution. Advanced sample-preparation techniques and visualization methods using transmission electron microscopy were used to observe directly the micro- and nano-scale clay—OM fabric of the resulting flocs. Such direct observation elucidated the role of OM in clay flocculation; few attempts have been made in the past due to the technical difficulties in preserving the original structure. A comparison of clay fabric at two different ionic strengths of 0 and 0.14 M revealed that the individual hexagonal clay particles settled slowly with little intra-aggregate void space (void ratio: 0.07) at 0 M while rapid flocculation and settling of clay particles at 0.14 M, with or without OM, resulted in a more open fabric with greater void space (void ratio: 0.33). The silver-staining technique demonstrated effectively the location of electron-transparent chitin in montmorillonite aggregates. Chitin appeared to link the face-to-face (FF) contacts of clay domains by bridging between negatively charged face surfaces. However, the resultant void ratio and the average hydrodynamic diameter (dH) values were lower than in the OM-free system after flocculation. The results indicated that the interplay between ionic strength and OM content affected the floc architecture and void ratio.

Introduction:
With persistent incidence, incomplete vaccination rates, confounding respiratory illnesses, and few therapeutic interventions available, COVID-19 continues to be a burden on the pediatric population. During a surge, it is difficult for hospitals to direct limited healthcare resources effectively. While the overwhelming majority of pediatric infections are mild, there have been life-threatening exceptions that illuminated the need to proactively identify pediatric patients at risk of severe COVID-19 and other respiratory infectious diseases. However, a nationwide capability for developing validated computational tools to identify pediatric patients at risk using real-world data does not exist.
Methods:HHS ASPR BARDA sought, through the power of competition in a challenge, to create computational models to address two clinically important questions using the National COVID Cohort Collaborative: (1) Of pediatric patients who test positive for COVID-19 in an outpatient setting, who are at risk for hospitalization? (2) Of pediatric patients who test positive for COVID-19 and are hospitalized, who are at risk for needing mechanical ventilation or cardiovascular interventions?
Results:This challenge was the first, multi-agency, coordinated computational challenge carried out by the federal government as a response to a public health emergency. Fifty-five computational models were evaluated across both tasks and two winners and three honorable mentions were selected.
Conclusion:This challenge serves as a framework for how the government, research communities, and large data repositories can be brought together to source solutions when resources are strapped during a pandemic.

Background
Mental health problems are elevated in autistic individuals but there is limited evidence on the developmental course of problems across childhood. We compare the level and growth of anxious-depressed, behavioral and attention problems in an autistic and typically developing (TD) cohort.
MethodsLatent growth curve models were applied to repeated parent-report Child Behavior Checklist data from age 2–10 years in an inception cohort of autistic children (Pathways, N = 397; 84% boys) and a general population TD cohort (Wirral Child Health and Development Study; WCHADS; N = 884, 49% boys). Percentile plots were generated to quantify the differences between autistic and TD children.
ResultsAutistic children showed elevated levels of mental health problems, but this was substantially reduced by accounting for IQ and sex differences between the autistic and TD samples. There was small differences in growth patterns; anxious-depressed problems were particularly elevated at preschool and attention problems at late childhood. Higher family income predicted lower base-level on all three dimensions, but steeper increase of anxious-depressed problems. Higher IQ predicted lower level of attention problems and faster decline over childhood. Female sex predicted higher level of anxious-depressed and faster decline in behavioral problems. Social-affect autism symptom severity predicted elevated level of attention problems. Autistic girls' problems were particularly elevated relative to their same-sex non-autistic peers.
ConclusionsAutistic children, and especially girls, show elevated mental health problems compared to TD children and there are some differences in predictors. Assessment of mental health should be integrated into clinical practice for autistic children.

Objective:
To describe a pilot project infection prevention and control (IPC) assessment conducted in skilled nursing facilities (SNFs) in New York State (NYS) during a pivotal 2-week period when the region became the nation’s epicenter for coronavirus disease 2019 (COVID-19).
Design:A telephone and video assessment of IPC measures in SNFs at high risk or experiencing COVID-19 activity.
Participants:SNFs in 14 New York counties, including New York City.
Intervention:A 3-component remote IPC assessment: (1) screening tool; (2) telephone IPC checklist; and (3) COVID-19 video IPC assessment (ie, “COVIDeo”).
Results:In total, 92 SNFs completed the IPC screening tool and checklist: 52 (57%) were conducted as part COVID-19 investigations, and 40 (43%) were proactive prevention-based assessments. Among the 40 proactive assessments, 14 (35%) identified suspected or confirmed COVID-19 cases. COVIDeo was performed in 26 (28%) of 92 assessments and provided observations that other tools would have missed: personal protective equipment (PPE) that was not easily accessible, redundant, or improperly donned, doffed, or stored and specific challenges implementing IPC in specialty populations. The IPC assessments took ∼1 hour each and reached an estimated 4 times as many SNFs as on-site visits in a similar time frame.
Conclusions:Remote IPC assessments by telephone and video were timely and feasible methods of assessing the extent to which IPC interventions had been implemented in a vulnerable setting and to disseminate real-time recommendations. Remote assessments are now being implemented across New York State and in various healthcare facility types. Similar methods have been adapted nationally by the Centers for Disease Control and Prevention.

Self-Practice/Self-Reflection (SP/SR) has been proposed both as an adjunct to therapy training programmes, and also as a means for therapist development among experienced therapists. Research suggests it develops aspects of knowledge and skill that may not be addressed through other training methods. With increasing interest in SP/SR, a growing evidence base regarding both participant benefits and potential risks from SP/SR, and the development of SP/SR programmes across a range of therapeutic modalities, we argue it is timely to identify a set of principles that can guide the design, adaptation and implementation of SP/SR programmes. At this stage, there is little empirical evidence to guide trainers wishing to implement SP/SR in different contexts. Accordingly, these principles have been derived from reflection on developing, testing and implementing SP/SR programmes as well as on other training and supervisory experience. The first set of principles detailed in Section 1 draw on various theories of learning and development and frame the processes involved, the next principles speak to the content of SP/SR programmes, and the final principles address structure. Within Section 2, the principles are then considered for their practical implications. In Section 3, the sharing of what are initially private self-reflections is then considered together with some implications for SP/SR programmes, especially when there is assessment involved. We argue that SP/SR will continue to progress with well-designed standard programmes, careful implementation, thoughtful adaptation, ongoing innovation, and especially more evaluation.
Key learning aims(1) To understand the principles for designing, adapting and implementing SP/SR programmes that are drawn from theory and from the authors’ experience of developing and implementing SP/SR programmes over the last 20 years.
(2) To understand the possible factors that guide the processes, content and structure of SP/SR programmes.
(3) To understand how best to maximize effective engagement and learning (and limit harm) when planning or implementing an SP/SR programme.

Self-Practice/Self-Reflection (SP/SR) has been developed as a self-experiential training strategy to enhance CBT therapists’ skills. SP/SR gives therapists an experience of CBT through practising CBT techniques on themselves, and reflecting on the experience and its implications for clinical practice. Many practitioners report significant professional and personal gains from SP/SR; however, there is considerable individual variation. This study examined individual experiences of SP/SR in order to develop a better understanding of idiosyncratic variations in participants’ approaches to SP/SR, and to inform the design and implementation of future SP/SR programmes. A single-case design was employed to examine the experiences of four trainee cognitive-behaviour therapists who were undertaking SP/SR as part of their professional training in CBT. Quantitative data from self-ratings of skill, and qualitative data from participants’ reflections and attributions following completion of SP/SR were examined. Both the participants, and two additional reviewers were consulted in the interpretation of the results. The impact of SP/SR appeared specific to each participant, reflecting different ways that participants engaged with SP/SR materials. The study suggests that for optimal development, engagement of the personal self and therapist self may be required.

Many agricultural systems around the world are challenged by declining soil resources, a dry climate and increases in input costs. The cultivation of plants that are better adapted than current crop species to nutrient poor soils, a dry climate and low-input agricultural systems would aid the continued profitability and environmental sustainability of agricultural systems. This paper examines herbaceous native Australian legumes for their capacity to be developed as grain crops adapted to dry environments. The 14 genera that contain herbaceous species are Canavalia, Crotalaria, Cullen, Desmodium, Glycine, Glycyrrhiza, Hardenbergia, Indigofera, Kennedia, Lotus, Rhynchosia, Swainsona, Trigonella and Vigna. A number of these genera (e.g., Glycine, Crotalaria, Trigonella and Vigna) include already cultivated exotic grain legumes. Species were evaluated based on the extent to which their natural distribution corresponded to arid and semi-arid climatic regions, as well as the existing information on traits related to harvestability (uniformity of ripening, propensity to retain pod, pod shattering and growth habit), grain qualities (seed size, chemistry, color and the absence of toxins) and fecundity. Published data on seed yield were rare, and for many other traits information was limited. The Australian species of Vigna, Canavalia and Desmodium mainly have tropical distributions and were considered poorly suited for semi-arid temperate cropping systems. Of the remaining genera Glycyrrhiza and Crotalaria species showed many suitable traits, including an erect growth habit, a low propensity to shatter, flowers and fruits borne at the end of branches and moderate to large seeds (5 and 38 mg, respectively). The species for which sufficient information was available that were considered highest priority for further investigation were Glycine canescens, Cullen tenax, Swainsona canescens, Swainsona colutoides, Trigonella suavissima, Kennedia prorepens, Glycyrrhiza acanthocarpa, Crotalaria cunninghamii and Rhynchosia minima.

The compound eye of the tobacco hornworm moth Manduca sexta contains green-, blue-, and ultraviolet-sensitive photoreceptors. Electroretinogram spectral-sensitivity measurements were recorded from different regions of the retina in order to broadly map the distribution of the three receptor types. The relative contribution of the three receptors to spectral-sensitivity curves was estimated by fitting theoretical curves based on the absorption spectra of the three rhodopsins. This analysis indicated that the dorsal retina is green and ultraviolet dichromatic, with green-sensitive cells greatly predominating. The ventral retina is trichromatic with a substantial population of blue- and ultraviolet-sensitive receptors. We previously showed that flower visitation for nectar feeding is mediated mainly by blue-sensitive cells. Their localization in the ventral retina seems an appropriate adaptation of the receptor mosaic, since the moths hover above flowers as they feed.

Larvae of the tobacco hornworm moth Manduca sexta were reared on either a carotenoid-supplemented or a carotenoid-deficient diet. The former yields fortified adults with normal visual function, whereas visual sensitivity and rhodopsin content are reduced by 2−4 log units in the compound eyes of the deprived moths reared on the latter. We characterized the retinoids of fortified retinas and investigated the recovery of visual function in deprived moths that were provided with retinaldehyde as a source of photopigment chromophore. Retinoids were identified and measured by high-performance liquid chromatography (HPLC). Fortified retinas contained mainly 3-hydroxyretinaldehyde (R3); 11-cis R3 predominated in dark-adaptation, all-trans in light-adaptation, indicating that R3 is the photopigment chromophore. No retinoids could be measured in deprived eyes. Retinaldehyde (R1) was delivered to the retinas of deprived moths by “painting” solutions of 11-cis or all-trans R1 in dimethylsulfoxide (DMSO) on the corneal surfaces of the compound eyes or on the head capsule between the eyes. 11-cis R1 induced rapid recovery: during 3 days, sensitivity rose to within a log unit of that measured from fortified animals. By 7 days, sensitivity was close to normal. Although rhodopsin and P-face particle densities of photoreceptor membranes increased, neither rose to the levels found in fortified animals. All-trans R1 induced only a slight increase in sensitivity that could have resulted from some nonspecific isomerization of the all-trans to the 11-cis isomer; we found no evidence for a retinal isomerase that functions in darkness. Small amounts of R3 were measured in recovering retinas, indicating some conversion of R1 to R3. However, the chromophore of most of the rhodopsin that was synthesized must have been R1. It is possible that rhodopsin did not reach normal levels in the retina even after a week of recovery because the normal chromophore R3 was not provided. Although the rhodopsin that initially formed in recovering moths may have resulted from the association of the chromophore with pre-existing opsin, the extent of eventual recovery indicates that opsin synthesis was stimulated by 11-cis R1.

Two distinct opsin-encoding cDNAs, designated MANOP1 and MANOP2, were isolated as 3′ fragments from the sphingid moth Manduca sexta. They were obtained by reverse transcription of retinal RNA and amplification with the polymerase chain reaction (PCR) using a degenerate primer designed to an amino-acid sequence conserved in arthropod opsins. The cDNA fragments labelled bands at approximately 1.8 kb on Northern blots of retinal RNA extracts. Levels of opsin message were compared in retinas from normal moths, whose diets were fortified with carotenoid precursors of the Manduca rhodopsin chromophore, 3-hydroxyretinal, and those reared on carotenoid/retinoid (vitamin A) deficient diets. The chromophore-depleted retinas contained more opsin mRNA; this was particularly true for MANOP2. Thus, the chromophore is not required for opsin gene transcription in Manduca.
