Authors: Borcia Ion Dan , Richter Sebastian , Borcia Rodica , Schön Franz-Theo , Harlander Uwe , Bestehorn Michael 
Published: February 2023

AbstractSurface wave resonance of a liquid (water) layer confined in a circular channel is studied both experimentally and numerically. For the experiment, eight unevenly distributed ultrasonic distance sensors measure the local height of the wave surface. The resonance curves show maxima only for odd multiples of the fundamental resonance frequency $$f_0$$

f
0

. We explained this behavior using a simple intuitive “ping-pong” like model. Collision of wave fronts can be observed for higher frequencies. Also, the wave reflection on the walls can be treated as wave collision with itself. The non-linearity seems to be weak in our study so the delay in the wave propagation before and after the collision is small. Time-space plots show localized propagating waves with high amplitudes for frequencies near resonance. Between the peaks low amplitude and harmonic patterns are observed. However, for higher frequencies, the frequency band for localized waves becomes wider. In the Fourier space-time plane, this can be observed as a point for the harmonic patterns or a superposition of two lines: one line parallel to wave-vector k axis corresponding to the excitation frequency $$f_0$$

f
0

and a second line with inclination given by wave propagation velocity $$\sqrt{gh}$$

. For planned future work, this result will help us to reconstruct the whole water surface elevation using time-series from only a few measurement points
Multi-view Feature Learning for the Over-penalty in Adversarial Domain Adaptation
Authors: Zhang Yuhong , Wu Jianqing , Zhang Qi , Hu Xuegang 
Published: February 2023

ABSTRACT
Domain adaptation aims to transfer knowledge from the labeled source domain to an unlabeled target domain that follows a similar but different distribution. Recently, adversarial-based methods have achieved remarkable success due to the excellent performance of domain-invariant feature presentation learning. However, the adversarial methods learn the transferability at the expense of the discriminability in feature representation, leading to low generalization to the target domain. To this end, we propose a Multi-view Feature Learning method for the Over-penalty in Adversarial Domain Adaptation. Specifically, multi-view representation learning is proposed to enrich the discriminative information contained in domain-invariant feature representation, which will counter the over-penalty for discriminability in adversarial training. Besides, the class distribution in the intra-domain is proposed to replace that in the inter-domain to capture more discriminative information in the learning of transferrable features. Extensive experiments show that our method can improve the discriminability while maintaining transferability and exceeds the most advanced methods in the domain adaptation benchmark datasets.
Integrating Functional Status Information into Knowledge Graphs to Support Self-Health Management
Authors: Dragoni Mauro , Bailoni Tania , Donadello Ivan , Martin Jean-Claude , Lindgren Helena 
Published: February 2023

ABSTRACT
Functional Status Information (FSI) describes physical and mental wellness at the whole-person level. It includes information on activity performance, social role participation, and environmental and personal factors that affect the well-being and quality of life. Collecting and analyzing this information is critical to address the needs for caring for an aging global population, and to provide effective care for individuals with chronic conditions, multi-morbidity, and disability. Personal knowledge graphs (PKGs) represent a suitable way for meaning in a complete and structured way all information related to people's FSI and reasoning over them to build tailored coaching solutions supporting them in daily life for conducting a healthy living. In this paper, we present the development process related to the creation of a PKG by starting from the HeLiS ontology in order to enable the design of an AI-enabled system with the aim of increasing, within people, the self-awareness of their own functional status. In particular, we focus on the three modules extending the HeLiS ontology aiming to represent (i) enablers and (ii) barriers playing potential roles in improving (or deteriorating) own functional status and (iii) arguments driving the FSI collection process. Finally, we show how these modules have been instantiated into real-world scenarios.
Variations in Summer Extreme Hot–Humid Events over Eastern China and the Possible Associated Mechanisms
Authors: He Wenyue , Chen Huopo , Ma Jiehua 
Published: February 2023

Abstract
This study aimed to explore the changing characteristics of summer, compound, extreme hot–humid events over eastern China in recent decades and the associated underlying mechanisms. Results showed that the summer extreme hot–humid events over eastern China have tended to increase but with strong interannual variability in recent decades. Further analyses indicated that the summer sea surface temperature (SST) anomalies over the northwest Pacific (NW Pacific) and western tropical Pacific, and the May Arctic sea ice concentration (SIC) anomalies are the key elements that are closely connected to the variations in extreme hot–humid events over eastern China. The positive SST anomalies over the NW Pacific in summer, on the one hand, could strengthen the local circulation patterns that lead to the anomalous anticyclonic circulation over eastern China. On the other hand, the positive SST anomalies over the western tropical Pacific excite an anomaly pattern similar to the Pacific–Japan pattern that weakens the westerly jet and enhances the anticyclone circulation anomalies over the upper level of eastern China. Both of them provide favorable conditions for extreme hot–humid events over eastern China with increased moisture and temperatures. The sensitivity experiments by the Community Atmosphere Model, version 5 (CAM5), with SST forcing yield similar influencing processes to the observations. Additionally, the effect of SIC may be potentially responsible for the hot conditions in extreme hot–humid events over eastern China. The signal of declining May SIC could persist to summer and then influence the SST anomalies to its south, which could also produce a beneficial background for extreme hot–humid events to increase over eastern China by exciting the Rossby wave train propagating southeastward across the Mongolia–Lake Baikal region.
Text mining attitudes towards climate change: Emotion and sentiment analysis of the Twitter corpus
Authors: Mi Zhewei , Zhan Hongwei 
Published: February 2023

Abstract
Media such as Twitter has become a platform for contemporary Americans to express their opinions and allow for reaction to public opinion. Climate change is a topic of ongoing social concern. Machine-automated processing facilitates big data analysis and is suitable for analyzing a large corpus of tweets. This paper uses R tools to conduct sentiment calculation and emotion analysis on the tweet corpus from 2015 to 2018 to present the overall tendency of citizens’ attitudes toward climate change topics. The keyword analysis finds that people focus on the message’s source; CLIMATE CHANGE and GLOBAL WARMING make an association. Supporters express FEAR and SURPRISE about extreme weather and opponents’ behavior, while opponents show ANGER, DISGUST and SADNESS about politicians manufacturing climate change stories about which they have no real feelings. This study also reveals that the automatic annotation tools are still inadequate, with limited emotion lexicon and identification of negation and sarcasm.
At the Very Apex: What the Supreme Court’s Student Speech Cases Have to Teach Us About a Constitutional Right to Education
Authors: Warnick Bryan R. , Thomas Christopher D. 
Published: February 2023

Background/Context: In the 1973 Rodriguez decision, the U.S. Supreme Court held that the Constitution does not guarantee a substantive federal right to education. So far, this holding has not been adequately contextualized with many other statements the Court has made concerning the nature of education in the constitutional order. For example, since the 1969 Tinker decision, the Court has repeatedly justified curtailing student free speech by appealing to important educational goods, but the necessity of providing these educational goods has not been harmonized with the Court’s denial of a federal right to education. Purpose/Objective/Research Question or Focus of Study: Is the Court’s denial of a constitutional right to education consistent with how education is formulated in the Court’s other decisions related to education, particularly as found in the student speech cases? Research Design: A “holistic analysis” is employed to examine the Supreme Court decisions related to education. This approach interprets the different strands of the Court’s decisions related to education in light of one another (a “dialogic task”) and places the Court’s decisions into a larger context of educational thought (a “contextual task”). Specifically, with respect to the dialogic task, the focus is on reading the Court’s decisions related to a federal right to education in light of its jurisprudence related to student speech; with respect to the contextual task, the focus is on clarifying the Court’s statements related to educational goods by putting them into context with educational philosophy and theory. Conclusions/Recommendations: The holistic analysis leads to three observations. First, the authors find that the Supreme Court has endorsed a range of goods associated with education, including both public and private goods. Second, the Court has framed these educational goods as being closely associated with constitutional norms and the democratic order. Third, in the student speech cases, the Court has argued that these public and private educational goods are so critical that they justify the curtailment of student speech rights under the First Amendment. Bringing these observations together, it is concluded that, because education is being linked to constitutionally relevant private individual goods, and because the attainment of those goods is critical enough to overcome student speech rights, then the attainment of those goods should itself be considered a substantive, individual, constitutional right.

Authors: Lee Megan , Smolderen Kim G , Ionescu Costin , Hillegass William B , Romain Gaelle , Mena-Hurtado Carlos 
Published: February 2023

Background: The prevalence of peripheral artery disease (PAD) and leg symptoms are higher in Black than White adults. We studied the effects of self-reported lower extremity symptoms and ankle–brachial indices (ABI) groups on outcomes. Methods: Black participants in the Jackson Heart Study with baseline ABI and PAD symptom assessments (exertional leg pain by the San Diego Claudication questionnaire) were included. Abnormal ABI was < 0.90 or > 1.40. Participants were divided into (1) normal ABI, asymptomatic, (2) normal ABI, symptomatic, (3) abnormal ABI, asymptomatic, and (4) abnormal ABI, symptomatic to examine their associations with MACE (stroke, myocardial infarction, fatal coronary heart disease) and all-cause mortality, using Kaplan–Meier survival curves and stepwise Cox proportional hazard models adjusting for Framingham risk factors. Results: Of 4586 participants, mean age was 54.6 ± 12.6 years, with 63% women. Compared with participants with normal ABI who were asymptomatic, participants with abnormal ABI and leg symptoms had highest risk of MACE (adjusted HR 2.28; 95% CI 1.62, 3.22) and mortality (aHR 1.82; 95% CI 1.32, 2.56). Participants with abnormal ABI without leg symptoms had higher risk for MACE (aHR 1.49; 95% CI 1.06, 2.11) and mortality (aHR 1.44; 95% CI 1.12, 1.99). Participants with normal ABI and no leg symptoms did not have higher risks. Conclusion: Among Black adults, the highest risk for adverse outcomes were in symptomatic participants with abnormal ABIs, followed by asymptomatic participants with abnormal ABIs. These findings underscore the need for further studies to screen for PAD and develop preventative approaches in Black adults with asymptomatic disease.

Published: February 2023

Study Design Randomized controlled animal experiment. Objectives To determine and compare the efficacy of riluzole, MPS and the combination of two drugs in a rat model with acute spinal trauma, electrophysiologically and histopathologically. Methods 59 rats were divided into 4 groups as control, riluzole (6 mg/kg, every 12 hours for 7 days), MPS (30 mg/kg, 2nd and 4th hours after injury) and riluzole + MPS. Spinal trauma was created and the subjects were followed for 7 days. Electrophysiological recordings were made via neuromonitoring. The subjects were sacrificed and histopathological examination was made. Results For the amplitude values, mean alteration in the period from the spinal cord injury to the end of the 7th day is 15.89 ± 20.00%, 210.93 ± 199.44%, 24.75% ± 10.13% increase and 18.91 ± 30.01% decrease for the control, riluzole, riluzole + MPS and MPS groups, respectively. Although the riluzole treatment group produced the greatest increase in amplitude, it was observed that no treatment provided a significant improvement compared to the control group, in terms of latency and amplitude. It was observed that there was significantly less cavitation area in the riluzole treatment group compared to the control group ( P = .020). ( P < .05). Conclusions Electrophysiologically, no treatment was found to provide significant improvement. Histopathologically, it was observed that riluzole provided significant neural tissue protection.

Published: February 2023

Introduction: Three-dimensional (3D) printing plays a rapidly expanding role in the field of craniomaxillofacial (CMF) surgery; however, the time and costs required to efficiently utilize this technology are highly variable. To better delineate the temporal and financial resources needed to establish an efficient workflow, we conducted a systematic review and meta-analysis of studies utilizing patient-directed 3D-printed constructs in the setting of CMF surgery. Methods: A systematic review was performed using PubMed, Web of Science, and Embase. In total, 1679 articles were screened and 45 met inclusion criteria. Primary outcomes included the costs of 3D-printed constructs and the time required for virtual surgical planning (VSP), 3D printing, surgery, and hospitalization. Results: The aggregated data assessed 751 patients, 738 surgeries, and 1136 3D-printed constructs. The most common surgical indication was post-neoplastic reconstruction (n = 304), and the most common surgical procedure was mandibular reconstruction (n = 287). Printed constructs were as follows: contour models (44.1%), guides (30.9%), implants (12.5%), splints (12.1%), and prostheses (0.5%). Printing was the longest contributor to the preoperative workflow, averaging 401.6 minutes, while VSP required, on average, only 98.6 minutes. There was no significant difference in VSP time between constructs printed in-house and those contracted from commercial vendors. However, constructs printed in-house were significantly cheaper than those procured from vendors, averaging $252.20 and $2735.50, respectively ( P < .001). Of articles reporting intraoperative time (n = 19), 78.9% reported significant reductions when using 3D-printed constructs. Conclusion: 3D printing, especially in-house workflows, may reduce costs and improve efficiency for CMF surgery.
The effect of delignification ratio on the PMMA occupation in poplar wood cell wall by the macro and micro comparative study
Authors: Zhang Haiyang , Xu Fucheng , Xu Linlin , Zheng Chaowei 
Published: February 2023

AbstractThe polymer/wood functional products may not be true nanocomposites due to the poor permeability of non-polar monomers into the hydrophilic wood cell wall. In this paper, methyl methacrylate (MMA) chosen as the representative non-polar monomer was used to impregnate wood with different lignin removal and then polymerized in situ in delignified wood to obtain polymethyl methacrylate/delignified wood (PMMA/DW). The larger 10 nm mesopores reduction in PMMA/DW-29.9 and the disappearance of the smaller 3 nm mesopores of PMMA/DW-51.7 indicated that the removal of lignin was beneficial for the penetration of MMA in the wood cell wall. When the lignin removal reached between 29.9 and 51.7%, the dimensional stability of PMMA/DW was improved, and it could be speculated that the resin began to enter the wood cell wall at this stage. In addition, the indentation modulus and hardness of the PMMA/DW cell wall were significantly increased when the lignin removal reached 29.9%. This result was consistent with the conclusion of the pore size analysis, which further confirmed that the nanopores of the cell wall were filled with PMMA when the lignin removal was greater than 29.9%. The results of this paper indeed provide a basis for the design of biomass functional nanocomposites.

Published: February 2023

AbstractMetformin (MET) is an anti-diabetic drug employed as the first-line therapy for patients of type II diabetes mellitus (T2DM). Overdosage of drugs leads to severe outcomes, and its monitoring in biofluids is vital. The present study develops cobalt-doped yttrium iron garnets and employs them as an electroactive material immobilized on a glassy carbon electrode (GCE) for the sensitive and selective detection of metformin via electroanalytical techniques. The fabrication procedure via the sol–gel method is facile and gives a good yield of nanoparticles. They are characterized by FTIR, UV, SEM, EDX, and XRD. Pristine yttrium iron garnet particles are also synthesized for comparison, where the electrochemical behaviors of varying electrodes are analyzed via cyclic voltammetry (CV). The activity of metformin at varying concentrations and pH is investigated via differential pulse voltammetry (DPV), and the sensor generates excellent results for metformin detection. Under optimum conditions and at a working potential of 0.85 V (vs. Ag/AgCl/3.0 M KCl), the linear range and limit of detection (LOD) obtained through the calibration curve are estimated as 0–60 μM and 0.04 μM, respectively. The fabricated sensor is selective for metformin and depicts a blind response toward interfering species. The optimized system is applied to directly measure MET in buffers and serum samples of T2DM patients.
LuxHMM: DNA methylation analysis with genome segmentation via hidden Markov model
Authors: Malonzo Maia H. , Lähdesmäki Harri 
Published: February 2023

Abstract
Background
DNA methylation plays an important role in studying the epigenetics of various biological processes including many diseases. Although differential methylation of individual cytosines can be informative, given that methylation of neighboring CpGs are typically correlated, analysis of differentially methylated regions is often of more interest.

Results
We have developed a probabilistic method and software, LuxHMM, that uses hidden Markov model (HMM) to segment the genome into regions and a Bayesian regression model, which allows handling of multiple covariates, to infer differential methylation of regions. Moreover, our model includes experimental parameters that describe the underlying biochemistry in bisulfite sequencing and model inference is done using either variational inference for efficient genome-scale analysis or Hamiltonian Monte Carlo (HMC).

Conclusions
Analyses of real and simulated bisulfite sequencing data demonstrate the competitive performance of LuxHMM compared with other published differential methylation analysis methods.
