AbstractDesign and engineering of novel low dimensional metamaterials allow for new applications in membrane technology, aerospace and automotive industries, architecture, robotics, medicine, and textiles. Such materials can be strong, flexible, transparent, and can be assigned with different functionalities. Here, the authors explore the possibility of 2D graphene oxide (GO) surface to guide self‐assembly of 4‐cyano‐4′‐pentylbiphenyl (5CB) molecules via multiple hydrogen bonding and their clustering in optically active phases. The encapsulation of 5CB in a 2D geometry and birefringent properties of 5CB are tuned by the regulation of interaction energy between GO surface and 5CB. Chemical reduction of GO‐5CB composites results in electrically conductive reduced graphene oxide‐5CB membranes which change optical properties in response to Joule heating. The sustainable approach to the design of robust and flexible optically active materials will allow the formation of other metamaterials with different functionalities for advanced applications.

AbstractWith the increasing development of infrared (IR) detection technologies for both military and civil applications, IR anti‐detection technologies, also known as thermal camouflage technologies, have attracted great attention in recent years. Decreasing the surface emissivity may be effective for high‐temperature targets, but fails for adaptive thermal camouflage in dynamic scenes where the background temperature varies. In this work, we demonstrate a flexible Janus functional film (JFF) for adaptive thermal camouflage. The JFF consists of a low emissivity (low‐ε) layer and a high heat capacity (high‐C) layer. The low‐ε layer can effectively suppress the IR radiation of the objects, thus reducing the temperature of the objects in IR camera, while the high‐C layer can make similar thermal response as the background. According to different environmental conditions, different surfaces of JFF can be selected as camouflage surface to achieve static or dynamic thermal camouflage effect. What's more, the substrate materials of JFF (i.e., high‐density polyethylene (HDPE), silica gel (SG)) enable the film with good flexibility and realize the encapsulation of the functional filler, thus improving its reliability of resisting water and oxygen. Such flexible JFF with high reliability, easy scalability, and low cost may hold great promise for broad applications in adaptive thermal camouflage.
The Compliance Conversation: Navigating Variations in Sterile Processing Practices

Published: October 2021

ABSTRACTBecause of the variety of guidelines for instrument processing and sterilization (eg, government regulations on infection prevention and control [IPC], manufacturers’ instructions for use, publications from professional organizations), practices may vary from one country or facility to another. The Joint Commission recommends that when creating or revising IPC‐related policies, organizations should use a hierarchical model to address relevant IPC requirements. Joint Commission International accredits health care organizations outside the United States using standards and a survey process similar to, but not the same as, The Joint Commission. During a survey, perioperative nurses should use facility policies and procedures to provide evidence of compliance with regulations, guidelines, and best practices for surgical instrument processing. This article provides an overview of national and international IPC guidelines, the hierarchical models for organizations to use to update policies at their facilities, and differences in sterilization load release practices inside and outside the United States.

Published: October 2021

AbstractThe intrinsic kinetics of the methanol dehydration to dimethyl ether over the laboratory‐synthesized and commercial γ‐alumina is studied. A set of kinetic models admitting different mechanisms of the reaction is developed. The developed kinetic models, as well as the kinetic models of the methanol dehydration presented in the literature, are experimentally verified. It is shown that the kinetic model admitting Langmuir–Hinshelwood mechanism with associative methanol adsorption is the only model which describes intrinsic methanol dehydration rate over either laboratory or commercial γ‐alumina catalyst. The estimated activation energies are 121 and 128 kJ/mol, methanol adsorption heats are 45 and 70 kJ/mol, and methanol adsorption entropies are 72 and 131 J/(mol × K) for the laboratory and commercial samples, respectively. The laboratory‐synthesized γ‐alumina may be successfully used for modeling and scaling the process that utilizes the commercial γ‐alumina catalysts.

Published: October 2021

AbstractMany water systems are challenged with uncertainty regarding service line material type. This work investigated using a simple drinking water flushed sampling approach and a more complicated and invasive sequential profile sampling approach to predict whether homes had an existing lead service line (LSL). Homes that never had an LSL (control groups) and homes with LSLs (study groups) in two communities having different degrees of corrosion control were sampled. Using control groups' results, community‐specific “threshold” lead levels were determined and compared to results from study groups. The flushed sampling maximum lead concentration (FMC) of lead accurately predicted 100% and 60% of LSL sites for the community with poor and good corrosion control, respectively. The weighted average sequential profile lead concentration (WASLC) increased the 40% not identified as LSL sites by fully flushed samples to 100%. The WASLC closely followed by the maximum sequential profile lead concentration were most reliable in identifying LSLs.

Published: October 2021

AbstractBackgroundThere is a rare need for postoperative non‐invasive positive pressure ventilation (NIPPV) following microvascular reconstruction of the head and neck. In midface reconstruction, the free flap vascular pedicle is especially vulnerable to the compressive forces of positive pressure delivery.CaseA 60 year old female with Amyotrophic Lateral Sclerosis (ALS) presented with squamous cell carcinoma of the anterior maxilla, for which she underwent infrastructure maxillectomy and fibula free flap reconstruction. To avoid tracheotomy, the patient was extubated postoperatively and transitioned to NIPPV immediately utilizing a full‐face positive pressure mask with a soft and flexible sealing layer. The patient was successfully transitioned to NIPPV immediately after extubation. The free flap exhibited no signs of vascular compromise postoperatively, and healed very well.ConclusionPostoperative non‐invasive positive pressure ventilation can be successfully applied following complex microvascular midface reconstruction to avoid tracheotomy in select patients without vascular compromise of the free flap.
The assessment of adverse childhood experiences in clinical settings: Practitioner competencies and perceptions
Authors: McFarlane Lindsay R. , Hawes David J. 
Published: October 2021

AbstractIssues concerning the screening and assessment of adverse childhood experiences (ACEs) in healthcare settings have been subject to growing scrutiny in recent years, yet relatively little is known about practitioner perceptions and competencies related to such practices. This study examined practitioner knowledge, ability and concerns about the assessment of ACEs among parents and children in clinical settings and the acceptability of a newly validated measure (The Adverse Life Experiences Scale, ALES) for this purpose. Participants were (N = 144) healthcare practitioners (predominantly psychologists, nurses, social workers and psychiatrists). Measures were completed online, and the effects of family characteristics on practitioner perceptions were tested experimentally using case vignettes. Participants indicated moderate‐to‐high levels of knowledge and ability regarding the assessment of ACEs, and the ALES demonstrated high levels of acceptability across hypothetical cases involving various levels of risk. Practitioner concerns about such assessment were also found to be influenced by the level of risk indicated by case referral information. Specifically, concerns that assessment would be too upsetting or time‐consuming were greater in response to a case with a high level of ACEs, compared to one with low‐to‐moderate ACEs (p < .05; large effect size). Practitioners demonstrated relatively high competencies regarding the assessment of ACEs and supported the use of the ALES for this purpose. Those families with the highest levels of ACEs may nonetheless be the least likely to receive such assessment in clinical settings.

AbstractObjectivesA diverse intratumoral T‐cell receptor (TCR) repertoire is associated with improved survival in diffuse large B‐cell lymphoma (DLBCL) treated with rituximab/cyclophosphamide/doxorubicin/prednisolone/vincristine (R‐CHOP) chemoimmunotherapy. We explored the impact of intratumoral TCR repertoire on interim PET (iPET) done after four cycles of R‐CHOP, the relationships between intratumoral and circulating repertoire, and the phenotypes of expanded clonotypes.MethodsWe sequenced the third complementarity‐determining region of TCRβ in tumor samples, blood at pre‐therapy and after four cycles of R‐CHOP in 35 patients enrolled in ALLGNHL21 trial in high‐risk DLBCL. We correlated the TCR diversity metrics with iPET status, gene expression profiles and HLA‐class I genotypes. We then sequenced the FACS‐sorted peripheral blood T cells in six patients, and pentamer‐sorted EBV‐specific CD8+ T cells in one patient from this cohort.ResultsCompared with iPET− patients, the intratumoral TCR repertoire in iPET+ patients was characterised by higher cumulative frequency of abundant clonotypes and higher productive clonality. There was a variable overlap between circulating and intratumoral repertoires, with the dominant intratumoral clonotypes more likely to be detected in the blood. The majority of shared clonotypes were CD8+ PD‐1HI T cells, and CD8+ T cells had the largest clonal expansions in tumor and blood. In a patient with EBV+ DLBCL, EBV‐specific intratumoral clonotypes were trackable in the blood.ConclusionThis study demonstrates that clonally expanded intratumoral TCR repertoires are associated with iPET+ and that the blood can be used to track tumor‐associated antigen‐specific clonotypes. These findings assist the rationale design and therapeutic monitoring of immunotherapeutic strategies in DLBCL.

AbstractConsidering the long‐term goal of the “Paris Agreement,” drastically reducing the CO2 emission of the energy sector as a whole is essential. Existing study showed an example of the energy portfolio (PF) in 2050 achieving the greenhouse gas emission reduction target (80% reduction compared to FY2013) by the transition of primary energy consumption to electricity by increased electrification due to reduction of cost and high energy efficiency of electricity.The study also pointed out that further study is required since it did not consider the cost of network developments due to the geographical distance between areas with large demand and where suitable for renewable integration. This paper explains the mathematical optimization model to derive the cost optimal deployment of renewables and the corresponding required development of the interconnection, and, by showing a preliminary calculation result, verified that it should be effective to use this model in the study to seek the future of the energy sector.
Fast 3D microwave imaging inside cavity with minimum number of antennas and modified inverse algorithm
Authors: Babazadeh Omid 
Published: October 2021

AbstractThis article proposes an optimized method for 3D microwave imaging of various unknown objects inside a perfect electric conductor cavity. The total field scattered field technique uses the finite difference time domain method to obtain scattered fields inside a cavity in the forward scattering problem. However, the conjugate gradient method is optimized and used alongside a combined regularization term in the inverse scattering problem, which is essential for the reconstruction process. A dipole antenna is located as an incident wave from the transmitting antenna. Besides, one antenna acts as the receiver. Identifying the unknown objects with different shapes, sizes, materials, and locations using the minimum number of transmitting and receiving antennas, and the newly developed algorithm with less computation time, are the main advantages of this article. Also, the implemented method can be used in the 3D microwave imaging of multi‐scattering problems.
Effects of structural fracture and in situ stress combination characteristics on the production of coalbed methane wells: A case in the Mabidong block, China

Published: October 2021

AbstractSimilar drilling, fracturing, and drainage techniques were adopted in the early stage of developing coalbed methane (CBM) in the Mabidong block, but the production of adjacent CBM wells was significantly different. The effects of coal seam depth, thickness, reservoir pressure, the ratio of desorption pressure and reservoir pressure, and gas content on the production of CBM wells are systematically studied. It is found that these parameters are not the critical control factors. The data of 107 observation points were obtained by using high‐precision structural fracture mapping technology, and four structural fracture development zones were delineated in the Mabidong block. Simultaneously, according to the in situ stress state, the Mabidong area is divided into an in situ stress tension state, and in situ stress compression state, and an in situ stress transition state. Based on structural fracture development and in situ stress state characteristics, four kinds of matching relationships are found: ① Structural fracture development and in situ stress state are tension or transition state. ② The structural fractures are developed, but the in situ stress state is in the compression state. ③ The structural fracture is not developed, and the in situ stress state is tension or transition state. ④ The structural fractures are not developed, and the in situ stress is in the compression state. The comprehensive analysis of the 19 CBM well production shows that the CBM well production is high when the structural fracture dense area and the in situ stress tension and transition area coincide, while the CBM well production is low when other matching relationships. The matching relationship's accuracy in controlling the CBM well production is 89%. The characteristics of structural fracture development and in situ stress state are the combined control factors of CBM well production in the Mabidong block.
Directionality matters: Board interlocks and firm internationalization

Published: October 2021

AbstractResearch SummaryThis paper examines an understudied aspect of network relationships—that is, direction of relational ties. Tie direction is important since it can shape when and how firms can benefit from the international experience of other firms. We focus on a specific type of network relationship—that is, interlocking directorates, which provides a clinical context to study directionality. We show that, due to their higher familiarity, identification, and executive power, focal firm directors serving in other firms' boards (i.e., outgoing ties) are more beneficial for utilizing partners' international experience. However, outside directors sitting on the boards of focal firms (i.e., incoming ties) can bring more useful first‐hand experience and facilitate international expansion once these ties get stronger. Theoretical and practical implications of these results are discussed.Managerial SummaryAs they grow internationally, firms need to manage risks and uncertainties of doing business abroad. In this regard, they can potentially benefit from the international experience of other firms in their network. We show how firms can realize these benefits by means of interlocking ties (i.e., shared board memberships). To that end, we examine the directionality of interlocking ties. Specifically, we argue that a firm's ability to utilize partners' experience for its own international expansion is greater when its directors sit on the boards of other firms (so‐called outgoing ties) compared to when other firms' directors sit on its own board (so‐called incoming ties). However, experience coming through incoming ties is more effective for a firm's international expansion once these ties get stronger.
A prevention science approach to promoting health and quality of life for individuals with intellectual and developmental disabilities

Published: October 2021

AbstractIntellectual and developmental disabilities (IDD) involve challenges with both cognitive functioning and activities of daily living. The field of IDD science and practice has often applied a Quality of Life framework to promoting well‐being for those with IDD, however health disparities persist. Taking a prevention science approach to promoting health and quality of life may be a particularly effective way to decrease health disparities among individuals with IDD by addressing the challenging biopsychosocial risks that individuals with IDD experience during early childhood. This commentary discusses the promise of applying prevention science theory, research, and practice to promoting the quality of life of individuals with IDD, while recognizing the historical, methodological, and ethical challenges to doing so. Several opportunities for research partnerships between prevention scientists and applied IDD researchers are proposed for basic science research, community‐based participatory research, Type 1 translational research, and Type 2 translational research.

Published: October 2021

AbstractObjectiveTo characterize pregnancies in which meconium‐stained amniotic fluid (MSAF) was incidentally discovered during elective caesarean delivery (CD), and to evaluate the association with adverse neonatal outcomes.MethodsA retrospective study was performed on all patients who underwent elective CD with singleton pregnancies between March 2011 and June 2020. Data analyzed included maternal, pregnancy, and neonatal characteristics. A comparison was made between pregnancies with clear amniotic fluid, MSAF, and thick MSAF.ResultsDuring the study period, 10 445 patients with singleton pregnancies underwent elective CD. Of them, 368 (3.5%) had MSAF and 31 (0.3%) had thick MSAF. Patients with MSAF gained more weight during pregnancy and suffered more from diabetes compared with patients with clear fluid. Significantly more pregnancies with MSAF had either oligohydramnios or polyhydramnios. Pregnancies in the thick‐MSAF group had more intrahepatic cholestasis of pregnancy. No differences were found between the groups in the composite adverse neonatal outcome, including 5‐min Apgar score, need for mechanical ventilation, and admission to the neonatal intensive care unit.ConclusionThe incidental finding of MSAF during elective CD is not associated with increased risks of adverse neonatal outcomes.

AbstractBACKGROUNDBiological treatment of landfill leachate is inhibited by high concentrations of ammonia and recalcitrant organic matter. This study investigated the addition of natural adsorbent materials, zeolite (clinoptilolite) and biochar, to enhance biological treatment of landfill leachate in sequencing batch biofilm reactors (SBBRs). Three bench‐scale SBBRs were set up with varying types of biofilm support media: (i) lightweight expanded clay aggregate (LECA) as a control (C‐SBBR); (ii) LECA + zeolite (CZ‐SBBR); and (iii) LECA + zeolite + biochar (CZB‐SBBR). SBBRs were operated with alternating anoxic and aerobic stages to promote total nitrogen (TN) removal via nitrification/denitrification.RESULTSExcellent TAN removal (>99%) was achieved in all three SBBRs throughout the study, most likely as a result of the favorable environmental conditions and long hydraulic retention time (HRTs) applied (nine or more days). Biochar addition in CZB‐SBBR resulted in significantly higher chemical oxygen demand (COD) (61–83%) and color (82–95% as UV456) removals compared with C‐SBBR (42–44% for COD and 28–33% for color) and CZ‐SBBR (34–45% for COD and 20–35% for color). High effluent nitrate (NO3−) concentrations initially were observed in CZB‐SBBR, most likely due to limited organic carbon availability for denitrification. However, after >1 year of operation, NO3− accumulation declined and TN removal of 81% was achieved, indicating that the main nitrogen removal pathway shifted from simultaneous nitrification/denitrification to partial nitritation/anammox.CONCLUSIONSZeolite/biochar amended SBBRs are a promising approach for enhanced landfill leachate treatment. © 2021 Society of Chemical Industry (SCI).
