Compact self‐multiplexing antenna with high isolation and small‐frequency ratio
Authors: Wu Ting , Wang Jia‐Wei , Wang Ming‐Jun 
Published: February 2023

AbstractIn this paper, a miniaturized quarter‐mode substrate integrated waveguide (QMSIW)‐based self‐multiplexing antenna is designed to achieve high isolation in terms of small‐frequency ratios. First, the cross‐shaped slot is introduced to split the antenna into four parts with different dimensions, equivalent to four QMSIWs with different frequencies. By adjusting the slot position parameters, the QMSIW can be adjusted independently. Second, the antenna placement is optimized by adjusting the position of the slot and applying the frequency spacing technique. The designed antenna operates in four similar frequency bands (4.8, 5.15, 5.5, and 5.8 GHz). The isolation of adjacent units is more remarkable than 35.1 dB, while the isolation of relative units is more excellent than 22.7 dB. The structure of the proposed planar antenna is simple and suitable for handheld microwave devices.

AbstractThis review article provides an overview of developments for arterial spin labeling (ASL) perfusion imaging in the body (i.e., outside of the brain). It is part of a series of review/recommendation papers from the International Society for Magnetic Resonance in Medicine (ISMRM) Perfusion Study Group. In this review, we focus on specific challenges and developments tailored for ASL in a variety of body locations. After presenting common challenges, organ‐specific reviews of challenges and developments are presented, including kidneys, lungs, heart (myocardium), placenta, eye (retina), liver, pancreas, and muscle, which are regions that have seen the most developments outside of the brain. Summaries and recommendations of acquisition parameters (when appropriate) are provided for each organ. We then explore the possibilities for wider adoption of body ASL based on large standardization efforts, as well as the potential opportunities based on recent advances in high/low‐field systems and machine‐learning. This review seeks to provide an overview of the current state‐of‐the‐art of ASL for applications in the body, highlighting ongoing challenges and solutions that aim to enable more widespread use of the technique in clinical practice.

AbstractIntroduction and HypothesisThe primary aim of this study was to compare the effect of bladder instillations using dimethyl sulfoxide (DMSO) with triamcinolone versus bupivacaine, triamcinolone, and heparin (BTH) in women with newly diagnosed interstitial cystitis/painful bladder syndrome. The primary outcome was improvement in symptoms measured using the O'Leary‐Sant Interstitial Cystitis Symptoms Index (ICSI) score. Secondary comparisons included changes in urinary frequency, nocturia, and bladder capacity.Materials and MethodsThis was a prospective, randomized study. Patients with a recent diagnosis of interstitial cystitis/painful bladder syndrome (IC/PBS) were randomized 1:1 to treatment with either 6 weekly bladder instillations of DMSO with triamcinolone or BTH. During follow‐up visits, patients completed the ICSI questionnaire, and bladder capacity was determined through the retrograde filling of the bladder. The χ2 test or Student's t test were used for data analysis.ResultsA total of 83 patients were randomized, and final analysis included 70 participants who completed the 6 weekly instillations (42 DMSO, 28 BTH). The groups were similar in baseline demographics and clinical characteristics, except for cystometric maximum capacity (DMSO 338.62± 139.44 mL, BTH 447.43 ± 180.38 mL, p = 0.01). In the DMSO group, 63% of patients had a greater than 29.5% reduction in total ICSI score versus 43% in the BTH group (p = 0.15). Nocturia and pain were significantly reduced in the DMSO group. There was a significant increase from baseline in bladder capacity for both groups.ConclusionIn women with newly diagnosed IC/PBS, bladder instillations with DMSO and triamcinolone provide greater improvement in pain and nocturia compared to BTH.

AbstractObjectiveTo evaluate the relationship between intraoperative neural response telemetry (NRT) and postoperative auditory testing outcomes in children.Study DesignRetrospective study.SettingTertiary‐care academic center.MethodsChildren who underwent cochlear implantation using the Cochlear Corporation device between 2010 and 2019 were included. Associations of average NRT and the slope of amplitude with postoperative auditory outcomes including functional auditory measure Infant‐Toddler Meaningful Auditory Integration Scale (IT‐MAIS), and speech perception testing (consonant‐nucleus‐consonant [CNC], Pediatric AzBio [BABY BIO], Hearing In Noise Test [HINT], and Northwestern University Children's Perception of Speech [NU‐CHIPS]), measured between 6 and 57 months after implantation, were assessed using Spearman's rank correlation (ρ).ResultsThirty‐eight patients (19 female, 19 male) and 54 ears were included. The median age of implantation was 20.6 months (range 9.6 months to 10.6 years). Eight (21%) children had neurologic disorders such as stroke, epilepsy, cerebral palsy, and other causes. Thirteen (34%) children had connexin mutations. Average NRT was not significantly correlated with postoperative auditory outcomes (IT‐MAIS [ρ = −0.08, p = .74], CNC [ρ = 0.19, p = .32], BABY BIO [ρ = 0.21, p = .29], HINT [ρ = 0.05, p = .83]) and NU‐CHIPS (ρ = 0.21, p = .28). The average slopes of amplitude and comfort level were not strongly correlated with any auditory outcomes (p > .05).ConclusionsIntraoperative NRT was not correlated with any postoperative functional auditory outcomes. Patient counseling should include discussions that a subpar intraoperative cochlear response does not preclude favorable speech and auditory outcomes.

Published: February 2023

AbstractObjectiveTo describe a novel lateral approach for hypoglossal nerve stimulator (HNS) implantation in women and provide evidence for its safety and efficacy.Study DesignRetrospective case series.SettingSingle academic medical center.MethodsWe identified patients implanted with HNS by a single surgeon from January 2017 to December 2021. Patient characteristics, postoperative complications, surgical duration, response to therapy, and need for revision surgery were recorded.ResultsOne hundred four patients were included, including 93 males and 11 females. The lateral approach for HNS implantation involves placing the chest incision for the implantable pulse generator and respiratory sensor lead vertically in the anterior axillary line instead of horizontally in the infraclavicular area. No changes are made to the stimulator lead placement. All female patients were implanted using a lateral approach and all male patients were implanted via the standard anterior approach. Half of the patients were implanted via a 2‐incision technique. The median surgical time duration was equivalent in male and female patients (119 [interquartile range (IQR): 105‐138] vs 126 [IQR: 115‐141], respectively). Revision was required in 2 (18%) females versus 6 (6%) males (p = .17). There were equivalent rates of therapy response as well as postoperative complications.ConclusionA more cosmetic lateral approach is feasible for HNS in female patients and has a similar rate of adverse events and therapy responsiveness. Additional considerations in female patients include the ability to tolerate mammography as well as HNS implantation in the setting of existing breast implants.

Published: February 2023

AbstractThe objective of this work is to examine the feasibility of revision endoscopic posterior costal cartilage graft (EPCCG) placement for posterior glottic stenosis (PGS) and bilateral vocal fold immobility (BVFI). Revision and primary cases were compared with respect to decannulation rates, and it was hypothesized that there would be no difference in outcomes. Twenty‐one patients met inclusion criteria (14 primary, 7 revision). Thirteen (62%) had a primary indication of PGS, and 8 (42%) were for BVFI. There were no differences between revision and primary groups with respect to age, gender, or comorbidities (p > .05). There was no difference between groups with respect to decannulation rate (85% primary vs 100% revision, p = .32). Thus, revision EPCCG appears to have comparable results to primary EPCCG with respect to decannulation rate and time to decannulation. EPCCG may be a feasible alternative to open airway reconstruction for PGS and BVFI in selected patients.

Published: February 2023

AbstractObjectivesTo examine and compare the outcomes of various surgical interventions for congenital laryngeal webs in terms of avoidance of tracheostomy, rate of decannulation, web recurrence, revision surgery, and mortality in children.Data SourcesFollowing Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, a systematic review was conducted on December 10, 2021, using a comprehensive search in PubMed, Web of Science, Cochrane library, and Embase with no date restriction.Review MethodsArticles on surgical intervention for congenital laryngeal webs in pediatric (<18 years) patients were included in the analysis. Articles including acquired laryngeal webs, no surgical intervention, or exclusively adult population were excluded.Results9027 articles were reviewed, 24 articles met the inclusion criteria and 126 patients were included. In patients with Grades I and II webs, there was no significant difference in rates of tracheostomy or decannulation, between endoscopic (100%) versus open approach (100%). For Grades III and IV webs, 96% of patients who received open surgery were decannulated or avoided tracheostomy compared to 84% of those managed endoscopically (p = 0.081). There were significantly lower rates of revision surgery in the open group compared to the endoscopic group (77.8% vs 30.9%, p = 0.008).ConclusionThis study showed no difference in rates of tracheostomy, decannulation, web recurrence, revision, or mortality between endoscopic and open approaches for the treatment of Grades I and II webs. For Grades III and IV, open surgical techniques achieved a lower revision rate. Results should be interpreted in light of associated increased morbidity with open procedures.

AbstractObjectiveThere are no official diagnostic tools to evaluate the weakness of the genioglossus muscle. We have developed a protocol for muscular assessment in patients with severe obstructive sleep apnea‐hypopnea syndrome (OSAHS) and evaluated its effectiveness.Study DesignCase and controls prospective study.SettingSleep Unit Hospital Quironsalud Marbella (Spain).MethodsTwenty‐nine cases and 20 controls were recruited. Patients were examined by a phonoaudiologist that performed biometric measurements and the Orofacial Myofunctional Evaluation With Scores (OMES), Friedman, and Epworth Sleepiness Scale (ESS). In addition, upper airway muscle strength measures were performed using the Iowa Oral Performance Instrument (IOPI) and Tongue Digital Spoon (TDS).ResultsThe final cohort consisted of 49 subjects, including 29 cases and 20 controls. According to the univariate and multivariate logistic regression analyses, ESS, OMES protocol, IOPI score, and TDS were associated with severe OSAHS. Multivariate regression revealed an IOPI score below 48 kps with an adjusted odds ratio (OR) of 9.96 (95% confidence interval [CI] 2.5‐39.1, p = .001), and a 0.72 specificity (Spe), a 0.79 sensitivity (Sens), and a 0.82 area under the curve (AUC). Similarly, an OMES score lower than 200 had an adjusted risk ratio of 4.02 (95% CI 2‐7, p < .001), 1 Spe, 0.79 Sens, and 0.98 AUC; and finally, TDS scores lower than 201 g/cm2 showed an adjusted OR of 27 (95% CI 4.74‐153.6, p = .0001), 0.66 Spe, a 0.93 Sens, and a 0.86 AUC.ConclusionOur findings suggest that severe OSAHS patients present different muscle patterns than controls.

Published: February 2023

AbstractInitialization of condensate water variables for convective‐scale weather forecasting has been a topic of active research for the last few years. In this article, we present the addition of hydrometeor fields as control variables of a three‐dimensional ensemble variational scheme (3DEnVar) for the cloud‐resolving model AROME‐France. Even without any direct assimilation of hydrometeor observations, analysis increments of hydrometeors can be produced via covariances with observed variables in the ensemble‐derived background‐error covariance matrix. Cycled forecast–analysis experiments in near‐operational conditions have been performed over a three‐month summer period. Three configurations are compared: (i) a control experiment without hydrometeor control variables, (ii) a test experiment with hydrometeor control variables but without cycling the resulting forecasts, and (iii) an experiment with hydrometeor variables and cycled forecasts. Compared with the control experiment, both hydrometeor experiments show a positive impact up to 9 hr of forecasts in terms of cloud cover, and in the first hour for precipitation. The spin‐up period, as evidenced by a reduction of precipitation forecast skill at the beginning of the forecasts, is reduced in length and intensity in the hydrometeor experiments.
Life cycle assessment of next generation non‐metallic bridges
Authors: Zerin Arifa Iffat , Kasuga Akio 
Published: February 2023

AbstractEmployments of highly durable low carbon technologies are crucial for mitigation of climate change ensuring sustainable infrastructures. In this perspective, a challenging initiative for ultra‐high durability low carbon prestressed concrete bridges utilizing sustainable zero cement concrete (STC‐ZERO) and non‐metallic reinforcement is undertaken. STC‐ZERO exhibiting high strength, low shrinkage, and low creep reduces carbon emission up to 70% compared to the conventional concrete as cement is entirely replaced. Aramid fiber PC tendons have no factor of deterioration of concrete thanks to nonexistence of corrosion. Accordingly, an AASTHO‐PCI BT‐72 PC girder bridge and a butterfly web bridge are designed incorporating this combination and compared with corresponding conventional bridges with respect to whole life carbon emissions. Since there are no repair and rehabilitation requirements, the whole life carbon emissions of next generation non‐metallic bridges are expected to be reduced by around 70%.

“Don't Take Our Space”: Strategies, Agency, and Resistance in the White Space of a Dual Language Program
Authors: Martinez Negrette Giselle 
Published: February 2023

AbstractThis ethnographic case study investigates one dual language (DL) program in the midwestern United States. Drawing on concepts of “The White Space” (Anderson, 2015) and spaces of multilingualism (Blommaert et al., 2005), it explores the social perceptions, actions, and normative sensibilities of young children in a DL program where people of color are “typically absent, not expected, or marginalized when present” (Anderson, 2015, p. 10). This study shows how students and teachers co‐construct DL spaces and highlights how racially minoritized children resist, navigate, and (re)shape relationships in the White Space of the program. The article concludes by encouraging researchers and teacher educators to support DL teachers in their development of a critical consciousness to help them name and counteract inequities in DL programs.
A geometrical approach to nontrivial topology via exotic spinors
Authors: da Silva J. M. Hoff , Cavalcanti R. T. , Beghetto D. , da Rocha G. M. Caires 
Published: February 2023

Abstract
Exotic spinors arise in non-simply connected base manifolds due to the nonequivalent spinor structure. The dynamics of exotic spinors are endowed with an additional differential factor. In this work, we merge the exotic spinor scenario with Cartan’s spinor viewpoint, according to which a given spacetime point is understood as a kind of composition of spinor entries. As a result, we arrive at a geometrical setup in which the Minkowski metric is perturbed by elements reflecting the nontrivial topology. Such corrections shall be felt by any physical system studied with the resulting bilinear form. Within the flat spacetime context, we investigate quasinormal modes arising from the interference of nontrivial topology in the scalar field dispersion relation.
State-dependent Riccati equation feedback stabilization for nonlinear PDEs
Authors: Alla Alessandro , Kalise Dante , Simoncini Valeria 
Published: February 2023

AbstractThe synthesis of suboptimal feedback laws for controlling nonlinear dynamics arising from semi-discretized PDEs is studied. An approach based on the State-dependent Riccati Equation (SDRE) is presented for 2 and ∞ control problems. Depending on the nonlinearity and the dimension of the resulting problem, offline, online, and hybrid offline-online alternatives to the SDRE synthesis are proposed. The hybrid offline-online SDRE method reduces to the sequential solution of Lyapunov equations, effectively enabling the computation of suboptimal feedback controls for two-dimensional PDEs. Numerical tests for the Sine-Gordon, degenerate Zeldovich, and viscous Burgers’ PDEs are presented, providing a thorough experimental assessment of the proposed methodology.
Catalytic Oxidation of Propane and Carbon Monoxide by Pd Nanoparticles on Mn/TiO2 Catalysts

Published: February 2023

AbstractThe present work shows experimental results on the catalytic oxidation of C3H8and CO by Pd nanoparticles supported on MnOx/TiO2synthesized by the sol–gel method. The results show a strong interaction between Pd and MnOx/TiO2; likewise, the annealing temperature of the TiO2support modified the catalytic properties of the Pd–MnOx/TiO2catalyst. In this line, the catalysts with 1 and 2 wt% of Pd loading supported on MnOx/TiO2showed outstanding catalytic activity oxidizing C3H8and CO within two temperature intervals: 200–400 °C and 25–200 °C, respectively. The Pd–MnOx/TiO2catalyst also displayed very high stability during long-term tests and the addition of Pd nanoparticles reduced greatly the oxidation temperature of MnOx/TiO2. The outcomes revealed that the Pd–Mn interaction promoted the formation of new Pd0/Pd2+active sites as well as the formation of oxygen vacancies and reduced Ti4+to Ti3+species, which led to the improvement of the Mn3+and Mn4+redox features, thus boosting the catalytic oxidation capacity of the Pd–MnOx/TiO2catalyst.Graphical Abstract

AbstractThe presence and persistence of pesticides in the environment are environmental problems of great concern due to the health implications for humans and wildlife. The persistence of DDT–DDE in a Mediterranean coastal plain where pesticides were widely used and were banned decades ago is the aim of this study. Different sources of analytical information from water and soil analysis and topography and geographical variables were combined with the purpose of analyzing which environmental factors are more likely to condition the spatial distribution of DDT–DDE in the drainage watercourses of the area. An approach combining machine learning techniques, such as Random Forest and Mutual Information (MI), for classifying DDT–DDE concentration levels based on other environmental predictive variables was applied. In addition, classification procedure was iteratively performed with different training/validation partitions in order to extract the most informative parameters denoted by the highest MI scores and larger accuracy assessment metrics. Distance to drain canals, soil electrical conductivity, and soil sand texture fraction were the most informative environmental variables for predicting DDT–DDE water concentration clusters.
