AbstractIn two-dimensional (2D) metallic kagome lattice materials, destructive interference of electronic hopping pathways around the kagome bracket can produce nearly localized electrons, and thus electronic bands that are flat in momentum space. When ferromagnetic order breaks the degeneracy of the electronic bands and splits them into the spin-up majority and spin-down minority electronic bands, quasiparticle excitations between the spin-up and spin-down flat bands should form a narrow localized spin-excitation Stoner continuum coexisting with well-defined spin waves in the long wavelengths. Here we report inelastic neutron scattering studies of spin excitations in 2D metallic kagome lattice antiferromagnetic FeSn and paramagnetic CoSn, where angle resolved photoemission spectroscopy experiments found spin-polarized and nonpolarized flat bands, respectively, below the Fermi level. Our measurements on FeSn and CoSn reveal well-defined spin waves extending above 140 meV and correlated paramagnetic scattering around Γ point below 90 meV, respectively. In addition, we observed non-dispersive excitations at ~170 meV and ~360 meV arising mostly from hydrocarbon scattering of the CYTOP-M used to glue the samples to aluminum holder. Therefore, our results established the evolution of spin excitations in FeSn and CoSn, and identified anomalous flat modes overlooked by the neutron scattering community for many years.

AbstractOlder adults with lower education are at greater risk for dementia. It is unclear which brain changes lead to these outcomes. Longitudinal imaging-based measures of brain structure and function were examined in adult individuals (baseline age, 45–86 years; two to five visits per participant over 1–9 years). College degree completion differentiates individual-based and neighborhood-based measures of socioeconomic status and disadvantage. Older adults (~65 years and over) without a college degree exhibit a pattern of declining large-scale functional brain network organization (resting-state system segregation) that is less evident in their college-educated peers. Declining brain system segregation predicts impending changes in dementia severity, measured up to 10 years past the last scan date. The prognostic value of brain network change is independent of Alzheimer’s disease (AD)-related genetic risk (APOE status), the presence of AD-associated pathology (cerebrospinal fluid phosphorylated tau, cortical amyloid) and cortical thinning. These results demonstrate that the trajectory of an individual’s brain network organization varies in relation to their educational attainment and, more broadly, is a unique indicator of individual brain health during older age.

Published: November 2021

Purpose:
This study aimed to analyze the immediate effect on a singer's voice of a flexible silicone tube immersed in water combined with ascending and descending vocalise scales compared with ascending and descending vocalise scales alone.

Method:
A pre- and post-intervention quasi-experimental study was conducted. Thirty adult singers between 18 and 45 years old with no laryngeal disorders performed the two techniques for 3 min each on different days. Acoustic measurements of frequency, jitter, shimmer, glottal-to-noise excitation ratio, noise, smoothed cepstral peak prominence (CPPS), maximum phonation time (MPT), voice range profile, and self-perceived vocal effort (Borg Category Ratio 10-BR Scale adapted for vocal effort) were assessed before and after performing the techniques.

Results:
The results indicated an increase in singers' CPPS and MPT values and a decrease in shimmer and noise when performing with a flexible silicone tube immersed in water combined with vocalise. The singers reported a perception of decreased vocal effort after both methods. However, the diminished perceived vocal effort became more pronounced with the tube phonation technique combined with vocalise.

Conclusions:
Phonation in tubes combined with vocalise improved the vocal acoustic parameters (including cepstral measurements), increased MPT, and diminished perceived vocal effort. Although using vocalise alone diminished perceived vocal effort, this decrease was more pronounced in the tube phonation technique combined with vocalise.
Grammatical Verb Errors: Differences Between English Learners With and Without Diagnosed Language-Based Learning Disabilities
Authors: Fumero Keisey , Wood Carla 
Published: November 2021

Purpose:
This study examines the written language samples of fifth grade English learner (EL) students with and without diagnosed language-based learning disabilities (LLDs) in an effort to explore the utility of such supplemental materials for aiding in differential diagnosis of ELs with and without LLDs.

Method:

This sample of 127 fifth grade students consisted of ELs without identified disabilities (
n
= 89) and ELs diagnosed with LLDs (
n
= 38). Written language samples from a classroom-based expository writing task were coded for grammaticality and specific verb type of errors. An analysis of variance (ANOVA) between the groups that differed by language abilities was conducted at two time points to compare the frequency of errors and the average change in grammaticality from the beginning of the school year to the end of the school year.

Results:
EL students with and without LLDs performed similarly at the beginning of the school year. ELs without LLDs showed greater average change in accuracy across the school year. Significantly, higher proportions of verb tense and verb omission errors were demonstrated by ELs with LLDs when compared with their EL peers at the end of the school year. Overall grammatical accuracy was also lower for ELs with LLDs.

Conclusions:
Group differences at the end of the school year were confirmed in types and rate of verb errors. Results support the potential clinical utility of monitoring verb errors in writing samples over time as a supplemental tool in diagnostic evaluations and assessments for progress monitoring.
Clinical Quiz—A Rare Case of Anal Canal Duplication in the Context of Currarino Syndrome
Authors: Connor Sean Jared , Brisighelli Giulia , Patel Nirav , Levitt Marc A. 
Published: November 2021

AbstractCurrarino syndrome (CS) is a rare condition that presents with any combination of a sacral defect, a presacral mass, and an anorectal malformation. This collection, referred to as Currarino's triad, may not necessarily present as all three abnormalities in the diagnosis of the syndrome. Anal canal duplication (ACD) is an even rarer occurrence. We present a case that lies on the CS spectrum with an associated ACD and discuss a complex surgical challenge that necessitated a customized management plan, devised through a multidisciplinary approach.
Access Route for Endovascular Neurointervention - Transfemoral to Transradial: Is it Worth the Effort and are we Ready for the Change?
Authors: Ahuja Chirag Kamal , Agarwal Vivek , Vyas Sameer , Gupta Vivek 
Published: November 2021

AbstractTransfemoral access for neurointerventions has been a time-tested technique of entering the vascular network of the body and reaching the intended targets. However, it has its own share of shortcomings in the form of long admission times leading to increased costs, patient inconvenience and local (though infrequent) adverse affects. Transradial route has taken the interventional cardiology domain by storm and is staring now at other vascular domains especially neurointervention. It has shown better outcomes than the transfemoral route in many aspects. The current article discusses the vascular access perspectives with an exhaustive overview of the transradial route concerning its historical perspectives, its requirement in the current clinical scenario, the procedure per se including the adverse effects and whether it has the real world charm to displace the transfemoral route into the backseat. Transradial access in neurointervention is here to stay, however it would require training, certain modifications in the standard catheters that one currently uses for cerebral procedures and constant practice by the operator to cross the learning curve and attain a certain level of competence before he becomes comfortable with the technique.

Abstract
Objectives Hypertension is a modifiable risk factor for numerous comorbidities and treating hypertension can greatly improve health outcomes. We sought to increase the efficiency of a virtual hypertension management program through workflow automation processes.
Methods We developed a customer relationship management (CRM) solution at our institution for the purpose of improving processes and workflow for a virtual hypertension management program and describe here the development, implementation, and initial experience of this CRM system.
Results Notable system features include task automation, patient data capture, multi-channel communication, integration with our electronic health record (EHR), and device integration (for blood pressure cuffs). In the five stages of our program (intake and eligibility screening, enrollment, device configuration/setup, medication titration, and maintenance), we describe some of the key process improvements and workflow automations that are enabled using our CRM platform, like automatic reminders to capture blood pressure data and present these data to our clinical team when ready for clinical decision making. We also describe key limitations of CRM, like balancing out-of-the-box functionality with development flexibility. Among our first group of referred patients, 76% (39/51) preferred email as their communication method, 26/51 (51%) were able to enroll electronically, and 63% of those enrolled (32/51) were able to transmit blood pressure data without phone support.
Conclusion A CRM platform could improve clinical processes through multiple pathways, including workflow automation, multi-channel communication, and device integration. Future work will examine the operational improvements of this health information technology solution as well as assess clinical outcomes.
Toward comprehensive exploration of the physisorption space in porous pseudomaterials using an iterative mutation search algorithm
Authors: Boone Paul , Wilmer Christopher E. 
Published: November 2021

We describe an updated algorithm for efficiently exploring structure–property spaces relating to physisorption of gases in porous materials. This algorithm uses previously described “pseudomaterials,” which are crystals of randomly arranged and parameterized Lennard-Jones spheres, and combines it with a new iterative mutation exploration method. This algorithm is significantly more efficient at sampling the structure–property space than previously reported methods. For the sake of benchmarking to prior work, we apply this method to exploring methane adsorption at 35 bars (298 K) and void fraction as the main structure–property combination. We demonstrate the effect and importance of the changes that were required to increase efficiency over prior methods. The most important changes were (1) using “discrete” mutations less often, (2) decreasing degrees of freedom, and (3) removing biasing from mutations on bounded parameters.

Context Shifting agricultural operations to more sustainable management practices is needed in the face of a changing climate. Aims In this study, the short-term effects of three tillage systems (no tillage, minimum tillage and conventional tillage) on a wide selection of soil properties in a semi-arid agrosystem of eastern Tunisia were assessed. Methods The studied soil properties included saturation percentage, bulk density, penetration resistance, mean weight diameter, electric conductivity, soil reaction, soil organic matter, carbonates, available phosphorus and exchangeable potassium. The impacts of tillage systems on soil quality indices (SQI) developed based on the total set of properties (SQI-T), or a minimum set (SQI-M) selected through principal component analysis, were also investigated. Key results Relative to conventional tillage, no tillage increased bulk density, penetration resistance and electrical conductivity, whereas minimum tillage affected only saturation percentage and pH. No tillage and minimum tillage did not enhance soil quality relative to conventional tillage. The SQI-T and SQI-M were highly correlated (r = 0.93) to each other suggesting that the outcomes of the two indices are comparable. Principal component analysis efficiently selected the most influential indicators of the effects of tillage systems on soil quality. Conclusions and implications Farmers in the study region are encouraged to consider minimum tillage during the early years of transition from standard to no tillage systems to avoid rapid decline in soil quality and consequent yield loss.
Pragmatics for cross-disciplinary collaboration.
Authors: Klein Julie Thompson 
Published: November 2021

Abstract

This chapter draws on the Field Guide, as well as on a recent study of the boundary work of collaborating in cross-disciplinary and crosssector work, with added insights from literature on team science. Heeding the editors' mandate to focus on pragmatics, it depicts the 'how' of collaboration across boundaries of expertise in short essays that define major dimensions. Each essay is framed at the start by keywords and ends with pertinent resources that individuals and groups may use in whole or in part for training modules and workshops, interventions in the course of actually conducting research, and formal curricula in higher education. The initial section of the chapter describes the overarching topic of collaboration, including the role of a collaboration plan and the centrality of communication. The remaining sections discuss three subtopics that are often linked with collaboration. The first, cross-disciplinary and crosssector work, reveals distinctions in kinds of teamwork. The second, integration, discloses degrees of interaction and synthesis. The third, leadership, describes typical needs and responsibilities. These shorter accounts of related concepts and approaches begin with definitions of crossdisciplinarity (spanning multi-, inter- and transdisciplinary approaches) and cross-sector work (bridging the academy, government, industry, and communities in the north and global south). After a short summary, the conclusion reflects on the importance of integrative expertise among all team members along with needed requisite competencies.
Human behaviour change models for improving animal welfare.
Authors: Carroll Grace A. , Groarke Jenny M. , Graham-Wisener Lisa 
Published: November 2021

Abstract

In this chapter, three key frameworks will be outlined, as well as how they fit together. This will allow animal welfare scientists to develop human behaviour change plans from start to finish. These three frameworks are (i) the theoretical domains framework (TDF; Michie et al., 2005); (ii) the behaviour change wheel (BCW; Michie et al., 2011, 2014); and (iii) the behaviour change technique taxonomy (BCTT; Michie et al., 2013). Each framework is described, and guidance is provided for applying these models to design effective human behaviour change interventions. Common pitfalls are outlined, and animal welfare examples are provided throughout to aid understanding.

Abstract
In this work, a SiGeSn/GeSn/SiGeSn single quantum well was grown and characterized. The sample has a thicker GeSn well of 22nm compared to a previously reported 9nm well configuration. The thicker well leads to: (i) lowered ground energy level in Γ valley offering more bandgap directness; (ii) increased carrier density in the well; and (iii) improved carrier collection due to increased barrier height. As a result, significantly enhanced emission from the quantum well was observed. The strong photoluminescence (PL) signal allows for the estimation of quantum efficiency (QE), which was unattainable in previous studies. Using pumping-power-dependent PL spectra at 20K, the peak spontaneous QE and external QE were measured as 37.9% and 1.45%, respectively.

Furthermore, the thermal behavior of the composite particles was investigated by differential scanning calorimetry, which showed that the composite particles inherited the energetic property of pure KPA crystals when the mass fraction of magnetic component was 50%, or 65%. As for the composite particles with 75% magnetic component, the thermal stability of was poor. In addition, the magnetic directional aggregation performance of composite particles was analyzed by dynamic simulation, which moved toward the magnetic source. For the composite particles with 50% magnetic component, the maximum concentration was about 63 times of the initial concentration, and the peak velocity was 0.63 m s−1. With the mass fraction of magnetic component increasing to 65%, the concentration and velocity of the composite particles generally increased at the corresponding moment. As the mass fraction of magnetic component increased to 75%, the change of them was not obvious. Therefore, the composite particles with

Counting the Lyapunov inflections in piecewise linear systems*
Authors: Ma Liangang 
Published: November 2021

Abstract
Following the pioneering work of Iommi–Kiwi and Jenkinson–Pollicott–Vytnova, we continue to study the inflection points of the Lyapunov spectrum in this work. We prove that for any three-branch piecewise linear expanding map on an interval, the number of its Lyapunov inflections is bounded above by 2. Then we continue to show that, there is a four-branch piecewise linear expanding map, such that its Lyapunov spectrum has exactly four inflection points. These results give an answer to a question by Jenkinson–Pollicott–Vytnova on the least number of branches needed to observe four inflections in the Lyapunov spectrum of piecewise linear maps. In the general case, we give upper bound on the number of Lyapunov inflections for any n-branch piecewise linear expanding maps, and construct a family of n-branch piecewise linear expanding maps with 2n − 4 Lyapunov inflections. We also consider the number of Lyapunov inflections of piecewise linear maps in terms of the essential branch number in this work. There are some results on distributions of the Lyapunov inflections of piecewise linear maps through out the work, in case of their existence.
Enhancement of photoelectrochemical performance in ferroelectric films via the introduction of an Au buffer layer

Published: November 2021

Abstract
The inefficient separation of photogenerated carriers has become a serious problem that limits the photoelectrochemical (PEC) performance of semiconductors. Herein, a sol-gel method was used to prepare BiFeO3 ferroelectric thin films with FTO and FTO/Au as substrates, respectively. The polarization electric field of the ferroelectric can more effectively separate the carriers generated in the photoelectrode. Meanwhile, the introduction of an Au buffer layer can reduce the resistance in the process of charge transfer, accelerate the carrier migration, and enhance the efficiency of the charge separation. Under light irradiation, Au/BiFeO3 photoelectrode exhibited an extraordinary improvement in PEC water splitting compared with BiFeO3. In addition, the ferroelectric polarization electric field causes band bending, which further accelerates the separation of electrons and holes and improves the PEC performance of the photoelectrode. This work promotes the effective application of ferroelectric films in PEC water splitting.

Abstract
The long-life, high yield deuterium-deuterium (D-D) neutron tube has become one of the research hotspots. Here, deuterated polyethylene target, heavy water target and titanium target were investigated by Stopping and Range of Ions in Matter (SRIM). The calculation showed that the deuterated polyethylene target, which was a potential target material, had the highest yield at an incident energy of 120 keV. Further, considering the unfavorable factors such as impurity ions and high temperature, the coating was used to protect the target material. Diamond, boron carbide, boron nitride, silicon carbide, and aluminum carbide were selected. The simulation results showed that the diamond composite deuterated polyethylene film had the best sputtering resistance, and the aluminum nitride composite heavy water target film had the lowest sputtering yield. The two coating materials shield the target, reduced the energy loss of incident ions, and provided a new method for the research of high yield and long life neutron tube.
