Published: September 2022

AbstractA considerable number of patients after the Fontan operation require prolonged hospitalization due to significant perioperative morbidities. The early postoperative morbidity can be attributed to elevated pulmonary vascular resistance. We hypothesized that the postoperative outcomes would improve with the routine use of inhaled nitric oxide (iNO) to decrease pulmonary vascular resistance. From January 2015 to November 2017 (Group 1), 37 patients underwent Fontan operation, and from December 2017 to December 2019 (Group 2), 34 patients underwent Fontan operation. All patients in Group 2 received iNO in the immediate perioperative period as part of a standardized postoperative pathway. There was no statistically significant difference in demographics or single ventricle subtype between the two groups. All patients underwent an extracardiac Fontan, and Group 2 had a higher number of fenestration (p< 0.01). Pre-Fontan hemodynamics showed no statistically significant difference in Glenn pressure, transpulmonary gradient, or systemic arterial and venous saturation. Both groups had a median length of stay of 13 days (p = 0.5), median chest tube placement of 7 days (p = 0.5), and there was no statistically significant difference in major complications. Readmission within 1 month of discharge occurred in five patients in Group 1 and six patients in Group 2 (p = 0.7). Routine use of iNO in the early postoperative period after Fontan operation did not reduce the length of stay, chest tube duration, rate of complications, or readmission.

Abstract
Background Intensivists indeed discharge neonatal intensive care unit (NICU) graduates after a period of physiological stability. There is, however, a real risk of life-threatening events at home. Survival after such episodes depends on time from arrest to initiation of basic life support (BLS). It is rational to train parents who would be first responders. We sought to measure objectively and prospectively, effect of BLS training on parents of NICU graduates on the psychomotor, cognitive, and affective domains of human learning.
Methods After face-to-face training sessions, proportion of home caregivers who obtained 100% marks on a pretested performance checklist for psychomotor skills of BLS on a mannequin were measured. Two other domains of learning and number of attempts required to obtain desirable results were also analyzed.
Results Median (interquartile range [IQR]) birth weight of the high-risk neonates was 1,050 g (930, 1570) and median gestational age was 29 (IQR 28, 33) weeks. More than 75% of parents had no prior exposure to BLS training. Among 46 trained caregivers, 80.4% achieved the desired score of 5 in the psychomotor performance checklist on the first attempt. A maximum of two attempts was required to reeducate and achieve score of 5 in the remaining caregivers. Forty-two (91.3%) caregivers obtained full marks on cognitive domain test. All caregivers responded positively toward affective domain questionnaire.
Conclusion It is possible to train parents in BLS measures and demonstrate their psychomotor skills on a mannequin effectively. No parents who were approached refused training or indicated anxiety in learning the skills required.
Consanguinity and Positive Family History of Inflammatory Bowel Diseases in Children: A Multicenter Case–Control Study

AbstractInflammatory bowel diseases (IBD), which comprise Crohn's disease (CD) and ulcerative colitis (UC), are rising trend in Saudi population. We aim to examine the association between consanguinity and family history and the risk of childhood IBD in Saudi children. A multicenter case–control study conducted in three tertiary hospitals in Jeddah and Riyadh, Saudi Arabia, during periods 2009 to 2021. Data about demographics, consanguinity, family history of IBD, and type of IBD were collected using a structured questionnaire. The same questionnaire was applied in matched case–control. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using unconditional logistic regression analysis that was performed to compare both groups. The study population included 335 children: 167 IBD patients (49.9%) and 168 controls (50.1%). Of these IBD, 93 patients (56%) were CD and 74 patients (44%) were UC. Most of participants were females (72.1%) and their age more than 10 years (51.5%). There was first-degree consanguinity in 66 IBD patients (49.6%). No significant difference in first-degree consanguinity between cases and controls was noted (49.6% in cases vs. 50.4% in controls; OR = 1.02; 95% CI = 0.66–1.57). The consanguinity showed a more significant association with CD than UC (p < 0.05). Family history of IBD (father, siblings, and grandparents) as risk factors for IBD was identified: paternal history of IBD (OR = 0.25, 95% CI = 0.08–0.76), siblings' history of IBD (OR = 2.16, 95% CI = 1.92–2.43), and grandparent's history of IBD (OR = 0.22, 95% CI = 0.07–0.65). Family history of IBD showed a more significant association with CD than UC (p < 0.05). Consanguinity is strongly associated with IBD with more significant association with CD than UC and may possibly explain IBD rise in Saudi Arabia. The greatest risk of family history of IBD is in first-degree relatives, especially in siblings' rather than parents and grandparents.
Active impedance matching of a cryogenic radio frequency resonator for ion traps

Published: September 2022

A combination of direct current (DC) fields and high amplitude radio frequency (RF) fields is necessary to trap ions in a Paul trap. Such high electric RF fields are usually reached with the help of a resonator in close proximity to the ion trap. Ion trap based quantum computers profit from good vacuum conditions and low heating rates that cryogenic environments provide. However, an impedance matching network between the resonator and its RF source is necessary, as an unmatched resonator would require higher input power due to power reflection. The reflected power would not contribute to the RF trapping potential, and the losses in the cable induce additional heat into the system. The electrical properties of the matching network components change during cooling, and a cryogenic setup usually prohibits physical access to integrated components while the experiment is running. This circumstance leads to either several cooling cycles to improve the matching at cryogenic temperatures or the operation of poorly matched resonators. In this work, we demonstrate an RF resonator that is actively matched to the wave impedance of coaxial cables and the signal source. The active part of the matching circuit consists of a varactor diode array. Its capacitance depends on the DC voltage applied from outside the cryostat. We present measurements of the power reflection, the Q-factor, and higher harmonic signals resulting from the nonlinearity of the varactor diodes. The RF resonator is tested in a cryostat at room temperature and cryogenic temperatures, down to 4.3 K. A superior impedance matching for different ion traps can be achieved with this type of resonator.

Hard-magnetic 3D-printer filaments made of 40 wt. % SrO(Fe2O3)6/PA12 composites made using a twin-screw extruder are being studied to be used for Magnetic Field Assisted Additive Manufacturing (MFAAM). The time dependence of the magnetic properties above the softening temperature of the PA12 matrix but below the melting point was studied using a biaxial Vibrating Sample Magnetometer (VSM). Specifically, the rotation of the magnetic particles in the softened polymer matrix after the application of a rotation field was extracted from the time dependent biaxial VSM signals. Above 132 °C, the strontium ferrite particles can rotate in the nylon matrix. The measured time constant decreases with temperature and magnitude of the rotation field. Model calculations indicate that, for 40 wt. % SrO(Fe2O3)6/PA12 at rotation fields of 500 Oe, the effect of the demagnetizing field on the angle between the magnetic moment and the particle’s easy axis is negligible, allowing one to determine the dynamic “melt” viscosity from the measured transients. The dynamic viscosity decreases from 2 × 105 Pa s at 132 °C to 3.1 × 104 Pa s at 175 °C with a sharp kink observed near 140 °C that correlates with a relaxation from the α′c phase for PA12 observed by others. A yield shear stress was observed for small rotation fields at low temperatures resulting in non-perfect alignment of the magnetic particles. The implications of the measurement results for MFAAM are discussed.

Published: September 2022

Unintentional C-related contamination can be readily introduced into the substrate in self-assembled molecular monolayer doping. These C contaminants can bind with dopants, forming interstitial defects, which will in return electrically deactivate the dopants. This issue will exacerbate when the dopant concentration is low. In this paper, a low temperature oxidation method (550 °C for 30 min) is introduced to remove carbon before the phosphorus dopants are driven into silicon in a rapid thermal annealing process. The samples with and without the pre-oxidation process are characterized by the Van der Pauw, low-temperature Hall effect measurements, and secondary ion mass spectrometry analysis. The results indicate that the surface carbon concentration in silicon is nearly completely removed with the pre-oxidation process, as a result of which the electrical activity of phosphorus is indeed increased.

Objective To describe self-reported general and psychological health for allied health practitioners at an Australian acute public health service over three time points within the coronavirus disease 2019 (COVID-19) pandemic. Methods This study collected data from cross-sectional online surveys at three time points: May–June 2020 (T1), October–November 2020 (T2) and November–December 2021 (T3). The self-report questionnaire consisted of demographic questions, a general health question and the 21-item version of the Depression Anxiety Stress Scales (DASS-21). Results A total of 308 responses were received (T1 n = 135, T2 n = 78, T3 n = 95) from representatives of eight allied health professions. The proportion of allied health practitioners reporting poor general health significantly increased over time, as did mean scores on all DASS-21 sub-scales. General health status was also significantly associated with DASS-21 subscale scores. Anxiety scores increased significantly between T1 and T2, while depression scores increased significantly between T2 and T3. Significant increases in stress scores were recorded across all time intervals. Between T1 and T3, the proportion of allied health practitioners reporting moderate, severe, or extremely severe symptoms increased for depression (10.3–30.9%), anxiety (5.2–18.2%) and stress (13.3–36.3%). Conclusion The general and psychological health of allied health practitioners appears to be worsening as the COVID-19 pandemic continues. Organisational strategies to support the health of the allied health workforce in acute care settings must address the cumulative effects of prolonged pressure on their general and psychosocial health. Support strategies need to be responsive to changes in psychological wellbeing at different phases of the pandemic.
The language-communication divide
Authors: Durrleman Stephanie , Peristeri Eleni , Tsimpli Ianthi Maria 
Published: September 2022

AbstractHas language developed to serve as a system of communication or one of thought? While language is clearly an excellent tool for communication, the possible contribution of higher order cognitive processes other than language to communication may provide insights on how we think about language evolution. Studies show that bilingualism improves communication skills, possibly due to boosting domain general processes, thus suggesting a divide between communication and formal language. However, to date little attention has been paid to bilingual atypical child populations presenting asymmetric developmental delays in language and communication skills. In this study, we explore the language-communication divide in bilingual and monolingual children diagnosed with High Functioning Autism (HFA), displaying primary communication difficulties, and those with Specific Language Impairment (SLI), displaying primary language difficulties. Children were tested on language, cognitive control, Theory of Mind (ToM), social comprehension and verbal communication. Results demonstrate that bilingual children with HFA exhibit enhanced cognitive control, ToM and social comprehension, which in turn improve their verbal communication as compared to their monolingual peers with HFA. On the other hand, no boost emerges in bilingual children with SLI, be it in cognitive control or ToM, though a weaker advantage (relative to the children with ASD) can be observed in their verbal communication skills, with significant mediation from social comprehension. The overall evidence suggests that language, though useful for communication, is not sufficient for communication, and may arguably not have evolved primarily for communicative purposes.
A case of constructional contamination in English
Authors: Hilpert Martin , Flach Susanne 
Published: September 2022

Abstract
This chapter discusses a case of what Pijpops and Van de Velde
(2016) call constructional contamination. Specifically, we investigate the influence of English modified
noun phrases on variation in adverb placement in the passive. On the basis of data from the COCA, we argue that highly
frequent nominal expressions such as sexually transmitted disease influence adverb placement in the
passive, which offers speakers a choice between adverb-initial order (The disease was sexually
transmitted) and adverb-final order (The disease was transmitted sexually). Our results
thus corroborate findings from Dutch corpora (Pijpops and Van de Velde 2016)
and suggest that construction al contamination is a phenomenon that can be observed across different languages. We
further discuss the role of constructional contamination for analogy and contrast.
Analogy and contrast at the morphology-syntax interface
Authors: Sokolova Svetlana 
Published: September 2022

Abstract
This chapter brings together the issues of analogy and contrast through a perspective of linguistic
borrowing. We analyze the integration of new [N[N]] compounds, borrowed from English into Russian (e.g.
top-igrok ‘top player’). By discussing two corpus studies and two small experiments, we show that
Russian new [N[N]] compounds reflect both “levelling” and “extension”. There are at least three factors that can block
“leveling”: statistical preemption, which is overridden by pragmatic factors; multiplicity of competing alternatives,
when several suffixes could be added to the stem to form a relational adjective; and semantics that leads to a split
between the two forms. Compound modifiers seem to represent terms and official titles, whereas adjective phrases
become qualitative, where possible, or pragmatic.
The nature of L2 input
Authors: Jung Boo Kyung 
Published: September 2022

Abstract
How language learners of Korean acquire knowledge on postpositions has been a long-standing research question in Korean
language pedagogy due to their polysemous nature. The present study investigates the nature of input involving the locative function of the
postposition -ey, one of the representative polysemous postpositions in Korean, through the frequency of its occurrence,
types of verbs co-occurring with -ey, and keyness analysis. Sejong written and spoken corpora and two types of textbooks
(eight volumes for each type: two volumes for four proficiency levels) for language learners of Korean are analyzed. Results show that
iss- ‘to be/exist’ predominantly occurred with locative -ey in the Sejong corpora and a few verbs
occupied a large proportion of the total usage. On the other hand, the most frequent verb was ka- ‘to go’ in all
proficiency levels of the textbooks, with the exception of the fourth level of the second-type textbook. This suggests that, while the
Sejong usage highlights its existential role, -ey for indicating destination is widely emphasized in the textbooks. Since
the purpose of language learning is to learn the structure and usage of the target language, this study’s findings can offer guidance in
setting and building pedagogical goals and directions.
Over-extremal brane shells from string theory?
Authors: Danielsson Ulf , Van Hemelryck Vincent , Van Riet Thomas 
Published: September 2022

Abstract
We demonstrate that, if the usual phenomenological compactifications of IIB string theory with warped throats and anti-branes make sense, there must exist spherical brane shells in 4d that are overcharged. They correspond to classical over-extremal objects but without the usual naked singularities. The objects are made from D3-particles that puff into spherical five-branes that stabilise at finite radii in 4d and whose inside corresponds to the supersymmetric AdS vacuum. One can think of these shells as stabilised Brown–Teitelboim bubbles. We find that these objects can be significantly larger than the string scale depending on the details of the warped compactification.
2D electrene LaH2 monolayer: an ideal ferrovalley direct semiconductor with room-temperature ferromagnetic stability

Abstract
In developing nonvolatile valleytronic devices, ferromagnetic (FM) ferrovalley semiconductors are critically needed due to the existence of spontaneous valley polarization. At present, however, the known real materials have various drawbacks towards practical applications, including the in-plane FM ground state, low Curie temperature (

From first-principles calculations, here we predict an ideal ferrovalley semiconductor, honeycomb LaH2 monolayer (ML), whose intrinsic properties can overcome all these shortcomings. We demonstrate that LaH2 ML, having satisfied structural stability, is a FM half-semiconducting electrene (

These results identify a much needed ideal ferrovalley semiconductor candidate, holding the promising application potential in valleytronics and spintronics devices.
Modal analysis of beam-like structures using multipoint dynamic testing vision system based on composite fringe pattern

Published: September 2022

Abstract
A multipoint dynamic testing vision-based system for beam-like structures based on composite fringe pattern (CFP) was proposed. The CFP was decorated on the surface of a beam as a sensor, whose image sequences were captured by a camera for dynamic identification. The CFP consists of two cosine fringe patterns. The fringes on both sides of the CFP are used to locate the measuring positions and the middle one is used to measure the spatial displacement of structures. The key advantage of the proposed method is that it can measure multipoint vibration information along the length direction of the beam at one measurement without point-by-point scanning. Experiments on two different beams were carried out, and the results show that the method can get multipoint vibration information and the modal shapes of the beam. Therefore, the vision and CFP-based measurement method is suitable for vibration monitoring and modal analysis of beam-like structures.

Published: September 2022

Abstract
Actinide-based compounds exhibit unique physics due to the presence of 5f electrons, and serve in many cases as important technological materials. Targeted thin film synthesis of actinide materials has been successful in generating high-purity specimens in which to study individual physical phenomena. These films have enabled the study of the unique electron configuration, strong mass renormalization, and nuclear decay in actinide metals and compounds. The growth of these films, as well as their thermophysical, magnetic, and topological properties, have been studied in a range of chemistries, albeit far fewer than most classes of thin film systems. This relative scarcity is the result of limited source material availability and safety constraints associated with the handling of radioactive materials. Here, we review recent work on the synthesis and characterization of actinide-based thin films in detail, describing both synthesis methods and modeling techniques for these materials. We review reports on pyrometallurgical, solution-based, and vapor deposition methods. We highlight the current state-of-the-art in order to construct a path forward to higher quality actinide thin films and heterostructure devices.
