Published: May 2022

AbstractThis paper reports on dielectric properties of ternary mixtures involving sodium chloride (NaCl) and sucrose (C12H22O11) dissolved into water (H2O). Broadband electromagnetic characterizations of such mixtures at various concentrations were performed, evidencing a dual behavior made of conductive effects at low frequencies and dipolar relaxation at microwave frequencies. Conductive and dielectric properties resulting from these both effects were integrated into predictive models for variations of Cole–Cole model parameters. Based upon this modelling, an innovative microwave-based sensor able to retrieve concentrations of both sodium chloride and sucrose in ternary aqueous solutions was introduced, designed, realized and assessed. The proposed sensor shows an error lower than 5.5% for concentration ranges of 0 to 154 mmol/L for sodium chloride and 0 to 877 mmol/L for sucrose.

AbstractHuman nonverbal social signals are transmitted to a large extent by vocal and facial cues. The prominent importance of these cues is reflected in specialized cerebral regions which preferentially respond to these stimuli, e.g. the temporal voice area (TVA) for human voices and the fusiform face area (FFA) for human faces. But it remained up to date unknown whether there are respective specializations during resting state, i.e. in the absence of any cues, and if so, whether these representations share neural substrates across sensory modalities. In the present study, resting state functional connectivity (RSFC) as well as voice- and face-preferential activations were analysed from functional magnetic resonance imaging (fMRI) data sets of 60 healthy individuals. Data analysis comprised seed-based analyses using the TVA and FFA as regions of interest (ROIs) as well as multi voxel pattern analyses (MVPA). Using the face- and voice-preferential responses of the FFA and TVA as regressors, we identified several correlating clusters during resting state spread across frontal, temporal, parietal and occipital regions. Using these regions as seeds, characteristic and distinct network patterns were apparent with a predominantly convergent pattern for the bilateral TVAs whereas a largely divergent pattern was observed for the bilateral FFAs. One region in the anterior medial frontal cortex displayed a maximum of supramodal convergence of informative connectivity patterns reflecting voice- and face-preferential responses of both TVAs and the right FFA, pointing to shared neural resources in supramodal voice and face processing. The association of individual voice- and face-preferential neural activity with resting state connectivity patterns may support the perspective of a network function of the brain beyond an activation of specialized regions.

AbstractThe quality factor (Q), describing the rate of energy loss from a resonator, is a defining performance metric for nanophotonic devices. Suppressing cavity radiative losses enables strong nonlinear optical responses or low-power operation to be achieved. Exploiting long-lived, spatially-confined bound states in the continuum (BICs) has emerged from the numerous approaches considered as a promising route to boost nanophotonic Q factors. Initial research explored the formation mechanisms of various types of BICs, drawing parallels to topological physics. With these fundamentals now established, we review the recent application of BICs in passive and active nanophotonic devices.

Published: May 2022

AbstractCities have grown rapidly—while they provide opportunities for many, they must also confront pervasive and rising inequality, unsustainable consumption, and growing vulnerability to the impacts of climate change. Recent research emphasizes the need to improve urban resilience and sustainability in the face of climate change, but offers circumscribed approaches that mostly focus on either (1) resource management and service provision, (2) social processes and capacities for transformation, or (3) governance and power relations among actors. Here, we embrace the emerging approach that considers urban areas as interdependent social-ecological-technological systems (SETS) and consider the implications for sustainable service provision; the role of bottom-up efforts in initiating urban transformations; and how governance may, under certain conditions, coordinate these efforts to effect broader change.
Ferrofluidic aqueous two-phase system with ultralow interfacial tension and micro-pattern formation
Authors: Rigoni Carlo , Beaune Grégory , Harnist Bent , Sohrabi Fereshteh , Timonen Jaakko V. I. 
Published: May 2022

AbstractFerrofluids are magnetic liquids known for the patterns they form in external magnetic fields. Typically, the patterns form at the interface between a ferrofluid and another immiscible non-magnetic fluid with a large interfacial tension γ ∼ 10−2 N m−1, leading to large pattern periodicities. Here we show that it is possible to reduce the interfacial tension several orders of magnitude down to ca. γ ∼ 10−6 N m−1 by using two immiscible aqueous phases based on spontaneous phase separation of dextran and polyethylene glycol and the asymmetric partitioning of superparamagnetic maghemite nanoparticles into the dextran-rich phase. The system exhibits classic Rosensweig instability in a uniform magnetic field with a periodicity of ∼200 μm, significantly lower than in traditional systems (∼10 mm). This system paves the way towards the science of pattern formation at the limit of vanishing interfacial tension and ferrofluid applications driven by small external magnetic fields.
Painting for a Purpose: A Visual Arts Program as a Method to Promote Engagement, Communication, Cognition, and Quality of Life for Individuals With Dementia

Published: May 2022

Purpose:
The arts (e.g., music and painting) have received considerable theoretical and observational support as a cognitive stimulation technique for persons living with dementia (PLWD). However, particularly for visual arts, limited empirical support exists. Therefore, the purpose of this study was to pilot a free-form arts program for PLWD in the context of a cognitive stimulation paradigm and measure subsequent engagement, communication, cognitive–linguistic function, and quality of life.

Method:
Three PLWD (one each in mild-to-moderate, moderate, and moderate-to-severe stages) were referred for study participation by a local long-term care facility. A single subject across subjects, ABA reversal design was used to assess intervention effects over a period of 8 weeks, in comparison to an active control condition (cooking activity). Cognitive–linguistic function and quality of life were assessed using standardized measures at baseline and follow-up. Engagement and communication were probed regularly across each study phase.

Results:
Significant changes were seen in participants' engagement and communication during painting sessions compared to the control activity. A nonsignificant positive trend was noted for self-rated quality of life from baseline to follow-up. Pre–post testing revealed nominal change in cognitive–linguistic functions.

Conclusions:
An arts program led to significant increases in constructive engagement and communication and a trend toward increased self-rated quality of life for the three PLWD. The fact that these changes were not sustained outside intervention sessions (i.e., pre–post testing) is consistent with the need for a larger paradigm shift in which rehabilitation specialists—including speech-language pathologists—better integrate creative, meaningful activities into the everyday lives of PLWD to maximize ongoing engagement, communication, and quality of life.

Authors: Maxwell Jamie , Rutherford Kelly , Holland Pamela , Fry Lisa , Rigon Arianna , Lankford Audrey 
Published: May 2022

Purpose:
This research intended to identify current practices being implemented with children who have a history or suspected history of opioid exposure, as well as challenges faced by speech-language pathologists in the schools.

Method:
Focus group data from three groups totaling 20 speech-language pathologists (SLPs) working in schools in West Virginia, also used in a previous study, were analyzed using qualitative thematic analysis to better understand SLP service provision to children with a history or suspected history of opioid exposure.

Results:
Results revealed two primary themes, reported as (a) service delivery in action (current practice trends and challenges) and (b) affective/cognitive manifestations (uncertainty about their role and various emotions expressed) of the SLPs who participated in the focus groups.

Conclusions:
This study revealed important clinical implications derived from the reports of participants. Particularly, the importance of communication and advocacy in the care of these children and the need to rethink what our scope of practice means when working with this vulnerable population are discussed.
Pansharpening scheme using spatial detail injection–based convolutional neural networks
Authors: Saxena Nidhi , Saxena Gaurav , Khare Neelu , Rahman Md Habibur 
Published: May 2022

AbstractPansharpening produces a high spatial‐spectral resolution pansharpened image by combining multispectral (MS) and panchromatic (PAN) images. In the traditional multi‐resolution analysis (MRA) method, detailed PAN images are extracted by transformation methods that are injected into MS images. This gives spatial and spectral distortions in the pansharpened image. These distortions can be reduced in the pansharpened image by the correct matching of the PAN detail image component. This correct matching is possible by the convolutional neural network (CNN)–based models. This paper obtains the detailed image component using the CNN models. This CNN model extracts the PAN detail image that is suitable for the MRA‐based pansharpening scheme which significantly reduces the spatial and spectral distortions. It is demonstrated by qualitative and quantitative analysis applied on GeoEye‐1 and IKONOS satellite images and shows the effectiveness of the proposed scheme.

AbstractThe current study focused on important bioactive compounds in plants that make them pharmacologically valuable. Therefore, this study was aimed to develop Lepidium sativum (L. sativum) seed extract loaded solid lipid nanoparticles and explore its cytotoxic effect on human liver cancer cells (HepG2 cells). The ethanolic extract of L. sativam used to develop L. sativum seed extract loaded solid lipid nanoparticles (SLNs) was analyzed by gas chromatography-mass spectrometry, thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) for phytochemical profiling. The L. sativum seed extract loaded SLNs were efficaciously prepared by the nanoprecipitation method and screened on the basis of physicochemical properties. The L. sativum seed extract loaded SLN-2 was characterized using various parameters like particle size (237.1±0.104), % entrapment efficiency (80±1.15), zeta potential (42.1±0.102) and % drug release (45% at the end 8 hours and release the entire amount in 12 h). The SLN-2 formulation was optimized based on the recipient factor, and SLN-2 was used to further evaluate the in vitro cytotoxicity of HepG2 cells in a dose-dependent manner by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay. The IC50 value of SLN2 was 52.37 ug/ml and sub IC50 26.1 ug/ml at 24 h and 48 h, respectively. Thus, we concluded that L. sativum extract loaded SLN-2 could act as an alternative therapy, possibly controlling therapeutic action by making a substantial reduction in side effects.

Abstract
Objectives The aim of this study was to identify the reasons for patient messages, phone calls, and emergency department (ED) visits prior to the first postoperative visit following discharge after endoscopic transnasal transsphenoidal (eTNTS) surgery.
Design This is a retrospective review of patients at a tertiary care academic center who underwent eTNTS for resection of a sellar region tumor between May 2020 and August 2021. Patient, tumor, and surgical characteristics were collected, along with postoperative, postdischarge, and readmission information. Regression analyses were performed to investigate risk factors associated with postdischarge phone calls, messages, ED visits, and readmissions.
Main Outcome Measures The main outcomes were the number of and reasons for phone calls, patient messages, and ED visits between hospital discharge and the first postoperative visit. We additionally determined whether these reasons were addressed in each patient's discharge instructions.
Results A total of 98 patients underwent eTNTS during the study period. The median length of hospital stay was 2 days (interquartile range [IQR]: 1–4 days), at which point most patients (82%) were provided with eTNTS-specific discharge instructions. First postoperative visit took place 9 days after discharge (IQR: 7–10 days). Within that time, 54% of patients made at least one phone call or sent at least electronic message and 17% presented to the ED. Most common reasons for call/message were nasal care, appointment scheduling, and symptom and medication questions.
Conclusion Through this work, we highlight the most common reasons for resource utilization via patient phone calls, messages, and ED visits among our cohort to better understand any shortfall or gap in the discharge process that may reduce these events.
Clinical Application of Ultrasound-guided Electrode Placement and Detection of Nerve Action Potential
Authors: Han Dong , Xu Le , Xu Jianguang 
Published: May 2022

Abstract
Background We explore a minimally invasive method (combined ultrasound detection, electrode placement and electrophysiologic nerve examination) to evaluate the early-stage quality of a nerve suture site.
Methods Ten patients with median and/or ulnar nerve injuries who had undergone nerve suture were recruited. Postoperative ultrasound examination found that the nerve injury was sutured. Then, a stimulating electrode and recording electrode were located beside the nerve proximal and distal to the suture site guided by ultrasound. Measurement of nerve action potentials (NAP) were performed with these electrodes, followed by surgical exploration. The pre- and intraoperative electrophysiologic findings were compared, together with amplitude, latency, and wave shape of NAP.
Results Of the 10 patients, 3 patients were diagnosed with median nerve injury, 2 with ulnar nerve injury, and 5 with the median nerve and ulnar nerve injury. NAP could not be detected pre- and intraoperatively in three median nerves from three patients and in two ulnar nerves from two patients. NAP was detected in 10 nerves from the remaining 5 patients. The pre- and intraoperative NAP results showed consistent results concerning the status of the nerve suture. Wilcoxon's signed-rank test indicated no significant difference in the amplitude and latency detected via sonographically placed electrodes and during surgical exploration. The number of negative-phase waves were equally distributed.
Conclusion Ultrasound-guided electrode placement and NAP detection can substitute surgery and serve as a minimally invasive approach to evaluate the regeneration of a sutured nerve.
Observation of Posttonsillectomy Wounds Using Endoscopy and Examination of the Postoperative Course by Wound Type

Published: May 2022

AbstractPalatine tonsillectomy is a surgical procedure that novice otolaryngologists should master early and is taught at many medical institutions. Unfortunately, however, the transoral procedure cannot provide a large enough field of view to doctors other than the one performing the operation. Therefore, it is difficult to share the surgical field and provide real-time teaching. Dissection of the wrong layer can cause postoperative bleeding and pain. Our department uses a 70-degree, 4-mm rigid endoscope for palatine tonsillectomy, which makes it possible for preceptors to teach tonsillectomy in real time and to evaluate the condition of the postoperative wound in detail. We classified the postoperative state after tonsillectomy into three stages, based on the degree of residual subcapsular connective tissue. We assessed the association between the amount of residual subcapsular connective tissue and the underlying disease that required indication for tonsillectomy, the postoperative course, and the operation time in 33 patients who had undergone palatine tonsillectomy at our institution between May 2017 and November 2020. We found that the more the subcapsular connective tissue that remained, the less the postoperative pain and bleeding. This association suggests that conserving the subcapsular connective tissue is important. Bringing the endoscope closer to the surgical field to observe the field without blind areas enables adequate hemostasis and easy sharing of the surgical field; therefore, this method is also effective for teaching tonsillectomy to surgical trainees.
Word Recognition Performance for Northwestern University Auditory Test No. 6 Word Lists in Quiet and in Competing Message
Authors: Stoppenbach Daniel T. , Craig Jeanne M. , Wiley Terry L. , Wilson Richard H. 
Published: May 2022

AbstractWord recognition norms were determined for the Northwestern University Auditory Test No. 6 (NU-6) released on the Department of Veterans Affairs (VA) Disc 1.1. Word recognition performance (in quiet and in competing message) was measured at 12 presentation levels for 24 young adults with normal hearing. Test-retest reliability also was evaluated. Word recognition scores for VA Disc 1.1 were generally higher than those reported for VA Disc 1.0. The differences in NU-6 scores across disc versions, however, were small and unlikely to affect clinical decisions based on word recognition tests. Score differences on test-retest for the VA Disc 1.1 version of the NU-6 with a competing message background also were small and unlikely to affect clinical outcomes. Overall, based on comparisons of scores for the disc versions of the NU-6, it appears that the two different recordings can be used interchangeably for clinical applications.

Triple-helix potential of the mouse genome
Authors: Maekawa Kaku , Yamada Shintaro , Sharma Rahul , Chaudhuri Jayanta , Keeney Scott 
Published: May 2022

SignificanceH-DNA is a non–B-form DNA structure containing intramolecular triplex and single-stranded DNA (ssDNA) regions. H-DNA–forming motifs include polypyrimidine•polypurine mirror repeat sequences, which occur frequently in eukaryotic genomes. These motifs have biological impacts on genome stability and processes such as replication and transcription, but their non-B DNA-forming potentials are not fully understood. Here, we show that the triplex-forming potential of H-DNA motifs in the mouse genome can be evaluated by a deep-sequencing technology that uses the ssDNA-specific nuclease S1 to detect ssDNA. It is currently unclear whether the H-DNA detected formed in vitro or was already present in vivo. Nevertheless, this study provides an approach to unveiling structural features of intramolecular triplexes genome-wide at high spatial resolution.
Korean pop culture reshaping Korean teaching
Authors: Kriukova Olga 
Published: May 2022

Abstract
Korean pop culture is becoming more and more popular outside of Korea and Asia. This trend draws enormous
attention to Korean culture, history, and of course, the language. Surveys show that more and more people are learning the
language precisely because of their love for Korean pop culture. Such a tendency could not but affect how Korean is taught. In
this article, I will look into how the syllabus, teaching methods, and materials used in the KFL classrooms have changed under the
influence of Korean pop culture. Moreover, in order to identify if the use of materials related to pop culture can benefit
students’ motivation and performance, I conducted an experiment with two groups of students, all starting their beginner-level
course (three months). The results of the study showed how the use of such materials in the classroom can affect students’
motivation and attitude toward learning.
