Get under the Umbrella: A Comprehensive Gateway for Researchers on Lanthanide‐Based Single‐Molecule Magnets
Authors: Bernot Kevin 
Published: July 2023

AbstractThe number of scientific articles that need to be considered to cover a research topic is ever‐increasing and quite difficult for a newcomer to assimilate. This is particularly true in dynamic discipline like Molecular Magnetism. In order to help young researchers in this field, this article proposes a “review of reviews” also known as an “umbrella review” on lanthanide‐based single‐molecule magnets (4 f‐SMM). As a preamble, various bibliographic search techniques and AI‐based tools for bibliographic search, indexing, and summarization are proposed and commented. Then, the main milestones in 4 f‐SMM are identified. In the core of the paper, books, book articles, and reviews dealing with 4 f‐SMM are contextualized and classified by subtopics. This article is therefore proposed as a gateway to the 4 f‐SMM field.
Estimating atmospheric motion winds from satellite image data using space‐time drift models
Authors: Sahoo Indranil , Guinness Joseph , Reich Brian J. 
Published: July 2023

AbstractGeostationary weather satellites collect high‐resolution data comprising a series of images. The Derived Motion Winds (DMW) Algorithm is commonly used to process these data and estimate atmospheric winds by tracking features in the images. However, the wind estimates from the DMW Algorithm are often missing and do not come with uncertainty measures. Also, the DMW Algorithm estimates can only be half‐integers, since the algorithm requires the original and shifted data to be at the same locations, in order to calculate the displacement vector between them. This motivates us to statistically model wind motions as a spatial process drifting in time. Using a covariance function that depends on spatial and temporal lags and a drift parameter to capture the wind speed and wind direction, we estimate the parameters by local maximum likelihood. Our method allows us to compute standard errors of the local estimates, enabling spatial smoothing of the estimates using a Gaussian kernel weighted by the inverses of the estimated variances. We conduct extensive simulation studies to determine the situations where our method performs well. The proposed method is applied to the GOES‐15 brightness temperature data over Colorado and reduces prediction error of brightness temperature compared to the DMW Algorithm.

Published: July 2023

AbstractThis paper discusses the nonlinear dynamic seismic response of a 14‐story reinforced concrete core wall building designed with the prescriptive requirements of the 2019 California Building Code for a near‐fault site in Los Angeles, California, simulated with a detailed nonlinear analysis of the complete structure and subjected to an ensemble of three‐component ground motion input. The study follows up on a recently published work by the authors, which examined the response of the specific building to static lateral loads. The nonlinear model of the building was developed in the software FE‐Multiphys using a shell‐element implementation of the beam–truss model (BTM). The BTM has been extensively validated through prior studies for planar, flanged, and coupled walls under static and dynamic loading. The building model was subjected to an ensemble of ground motions scaled at the design and risk‐targeted maximum considered earthquake levels. The vertical ground motion component and the out‐of‐plane shear degradation of wall piers were included in the simulations. The analyses elucidate the profound effect of nonlinear flexure–shear interaction and of the multidirectional behavior of the flanged coupled core wall on the evolution and localization of damage and on residual deformations. The coupling behavior between the core wall, the slabs, and the columns is also analyzed, and the importance of modeling the nonlinear behavior of all slabs for the residual damage evaluation is demonstrated. The aim of this study is to improve the understanding of issues arising from prescriptive design requirements as well as of issues associated with limitations of standard nonlinear seismic analysis.

Published: July 2023

AbstractObjectiveMulti‐family therapy (MFT‐AN) is a promising group‐based treatment for adolescent anorexia nervosa. This study aimed to explore how young people and parents perceived change to occur during MFT treatment.MethodsYoung people (10–18 years) diagnosed with anorexia nervosa or atypical anorexia nervosa and their parents who completed MFT‐AN alongside family therapy for anorexia nervosa within the preceding 2 years were eligible for this study. Semi‐structured qualitative interviews were conducted. Recordings were transcribed verbatim and analysed using reflexive thematic analysis.ResultsTwenty‐three participants (8 young people, 10 mothers and 5 fathers) completed interviews. Five main themes were identified; (1) Powerful connection, (2) Intensity, (3) New learning and perspective shifts, (4) Comparisons, and (5) Discharge is not recovery. There was a strong sense that being with others in a similar position in an intense environment were key factors in promoting change. Comparisons were inevitable and could promote insight and foster motivation, but could also be unhelpful at times. Participants spoke about how recovery continues beyond service use and requires ongoing attention and support.ConclusionsThrough the mechanisms of connection, intensity, new learning and comparisons change is perceived to occur in MFT‐AN. Some of these are considered unique to this treatment format.
Bioactive fatty acids from non‐conventional lipid sources and their potential application in functional food development
Authors: Akonjuen Bessem M. , Onuh John O. , Aryee Alberta N. A. 
Published: July 2023

AbstractThere is growing evidence that bioactive fatty acids (BFAs), including eicosapentaenoic acid (EPA; 20:5–3), docosahexaenoic acid (DHA; 22:6–3), and conjugated fatty acids offer multiple biological benefits and constitute ingredients in functional food development. Despite their potential, novel and alternative/nonconventional sources with unique bioactive properties to meet growing demand remain largely unexplored, poorly characterized, and their effects are not well understood. We systematically reviewed the literature to identify studies on alternative sources of BFAs, their functions, extraction, and application in the food and nutraceutical industry. Twenty studies delved into alternate sources such as plants, bacteria, and algae. Six studies found EPA and DHA as the dominant FA in algal sources, while ten studies reported several BFAs from plant sources. Five studies assessed the health benefits of docosapentaenoic acid (DPA), arachidonic acid (ARA), EPA, γ‐linolenic acid (GLA), and linoleic acid (LA). Eleven studies compared the quality of oil recovered by green solvents, pressurized liquid, supercritical fluid, and assisted extraction methods. Three studies assessed the effects of assisted extraction methods and reported that these approaches improved oil yield and quality, but the findings may have limited applicability to other lipid sources. The quality of nonconventional lipids largely depends on extraction techniques. Four studies suggested methods like 1D and 2D NMR spectroscopy, LC‐MS/MS; however, their analytical differences make accurate comparison inadequate. Five studies found that the incorporation of algal and seafood biolipids during product development increased EHA and DHA contents.
Rural pensions, intra‐household bargaining, and elderly medical expenditure in China
Authors: Chen Zeyuan , Park Albert 
Published: July 2023

AbstractChina's rural elderly spend less on medical expenditures as they age despite declining health, raising welfare concerns. This paper investigates the role of intrahousehold bargaining power on health expenditures of the elderly by evaluating the impact of cash transfers from a new social pension program. The program provided windfall payments to those above age 60, making it possible to employ a regression discontinuity design based on age of eligibility to estimate causal effects. Using data from the 2011 and 2013 waves of the China Health and Retirement Longitudinal Study, we find that receiving pension payments increases both the utilization of outpatient care and outpatient expenditures by the elderly who experienced illness. This result is robust to controlling for total household expenditures per capita, ruling out income effects as the main channel. Consistent with pensions increasing elderly bargaining power, we find that pensions significantly increase medical expenditures only for those elderly who co‐reside with children or grandchildren but have no effect on those who live independently.

AbstractObjectiveTo investigate DNA methylation (DNAm) status of dickkopf‐associated protein 1 (DKK‐1) in ossified hip capsule synovium and serum among patients with ankylosing spondylitis (AS).MethodsWestern blot was applied to detect the level of DKK‐1 protein expression in hip joint capsule tissues from four patients with AS as well as four patients with femoral neck fracture (FNF) caused by trauma as control. DKK‐1 gene promoter methylation (GPM) was examined by methylation‐specific polymerase chain reaction. Reverse transcription‐polymerase chain reaction was performed to examine the messenger RNA (mRNA) levels of DKK‐1, β‐catenin, and Wnt3a in both tissue and serum. The DNAm status of serum DKK‐1 was measured among 36 patients with AS and syndesmophytes (AS + syndesmophytes group), 40 patients with AS but no syndesmophyte (AS group), and 42 healthy individuals (control group). Also, the serum levels of DKK‐1 were measured by enzyme‐linked immunosorbent assay. The modified New York criteria (mNYC) together with the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) were adopted to examine the radiographic progression of AS. The receiver operating characteristic (ROC) curve was applied to investigate the diagnostic value of the methylation rate of DKK‐1 with regard to radiographic progression.ResultsThe expressions of DKK‐1 protein and mRNA in hip joint capsule tissues of AS patients were significantly lower, while DKK‐1 GPM rate, β‐catenin mRNA, and Wnt3a mRNA were markedly higher when compared with FNF group. For serum samples, the DKK‐1 methylation rate was significantly higher in AS+ syndesmophytes group in contrast to AS group and healthy controls. Serum levels of DKK‐1 protein and mRNA in AS with syndesmophytes group were markedly decreased, while β‐catenin mRNA and Wnt3a mRNA expressions were significantly increased than AS with no syndesmophyte group and the healthy control group. AS patients in Grade 4 showed a significantly higher serum DKK‐1 GPM rate than those in Grade 3 based on mNYC. Serum DKK‐1 GPM level was markedly and positively correlated with mSASSS. Serum levels of DKK‐1 in AS+ syndesmophytes group were markedly lower compared with AS but no syndesmophyte group and healthy controls. ROC curve analysis indicated that serum DKK‐1 methylation rate serves as a decent indicator for AS radiographic progression.ConclusionDNAm of DKK‐1 may correlate with pathological bone formation in AS, which may provide new strategies for the treatment of AS abnormal bone formation.

Published: July 2023

AbstractThe performance and stability of the electric network are improved through smart grid technologies. The smart grid strongly rely on digital communication technologies creates security issues that must be addressed to distribute power efficiently and safely. For billing, load balancing, and energy management, the customer‐side smart meter regularly transmits the consumption reading to the system operator. However, dishonest customers created cyberattacks by entering fictitious readings of their electrical consumption in order to steal electricity for financial benefit. The distributed monitoring meter‐based network concept is utilized in this paper to closely monitor the losses. A two‐stage clustering‐based technique has also been suggested for the purpose of detecting theft. The approach can be detect the customer ID having abnormality in consumption pattern. To verify the effectiveness of the suggested strategy, numerical experiments on two datasets of smart meters have been conducted and four different types of attack patterns have been constructed. Simulation results show that the proposed scheme is very effective for detecting various types of attack patterns. In addition, the paper helps to predict how much power and financial loss the company will suffer as a result of multiple attacks.
Microscale investigation of the anisotropic swelling of cartilage tissue and cells in response to hypo‐osmotic challenges

Published: July 2023

AbstractTissue swelling represents an early sign of osteoarthritis, reflecting osmolarity changes from iso‐ to hypo‐osmotic in the diseased joints. Increased tissue hydration may drive cell swelling. The opposing cartilages in a joint may swell differently, thereby predisposing the more swollen cartilage and cells to mechanical injuries. However, our understanding of the tissue–cell interdependence in osmotically loaded joints is limited as tissue and cell swellings have been studied separately. Here, we measured tissue and cell responses of opposing patellar (PAT) and femoral groove (FG) cartilages in lapine knees exposed to an extreme hypo‐osmotic challenge. We found that the tissue matrix and most cells swelled during the hypo‐osmotic challenge, but to a different extent (tissue: <3%, cells: 11%–15%). Swelling‐induced tissue strains were anisotropic, showing 2%–4% stretch and 1%–2% compression along the first and third principal directions, respectively. These strains were amplified by 5–8 times in the cells. Interestingly, the first principal strains of tissue and cells occurred in different directions (60–61° for tissue vs. 8–13° for cells), suggesting different mechanisms causing volume expansion in the tissue and the cells. Instead of the continuous swelling observed in the tissue matrix, >88% of cells underwent regulatory volume decrease to return to their pre‐osmotic challenge volumes. Cell shapes changed in the early phase of swelling but stayed constant thereafter. Kinematic changes to tissue and cells were larger for PAT cartilage than for FG cartilage. We conclude that the swelling‐induced deformation of tissue and cells is anisotropic. Cells actively restored volume independent of the surrounding tissues and seemed to prioritize volume restoration over shape restoration. Our findings shed light on tissue–cell interdependence in changing osmotic environments that is crucial for cell mechano‐transduction in swollen/diseased tissues.

AbstractBackgroundPatients with intestinal failure (IF) often present with abnormal body composition characterized by high fat mass. However, the distribution of fat and its association with the development of IF‐associated liver disease (IFALD) remain unclear. This study aims to investigate the body composition and its relationship with IFALD in older children and adolescents with IF.MethodsThis retrospective case‐control study enrolled patients with IF receiving parenteral nutrition (PN) at Keio University Hospital who initiated PN before the age of 20 years (cases). The control group included patients with abdominal pain, with available computed tomography (CT) scan and anthropometric data. CT scan images of the third lumbar vertebra (L3) were used for body composition analysis and compared between the groups. Liver histology was compared with CT scan findings in IF patients who underwent biopsy.ResultsNineteen IF patients and 124 control patients were included. To account for age distribution, 51 control patients were selected. The median skeletal muscle index was 33.9 (29.1–37.3) in the IF group and 42.1 (39.1–45.7) in the control group (P < 0.01). The median visceral adipose tissue index (VATI) was 9.6 (4.9–21.0) in the IF group and 4.6 (3.0–8.3) in the control group (P = 0.018). Among the 13 patients with IF who underwent liver biopsies, 11 (84.6%) had steatosis, and there was a tendency for fibrosis to correlate with VATI.ConclusionPatients with IF exhibit low skeletal muscle mass and high visceral fat, which may be related to liver fibrosis. Routine monitoring of body composition is recommended.

AbstractBackgroundThere is a great need for simple and inexpensive methods to quantify ammonia emissions in multi‐plot field trials. However, methods that meet these criteria have to be thoroughly validated. In the calibrated passive sampling approach, acid traps placed in the center of quadratic plots absorb ammonia, enabling relative comparisons between plots. To quantify ammonia emissions, these acid trap samplings are scaled by means of a transfer coefficient (TC) obtained from simultaneous measurements with the dynamic tube method (DTM). However, dynamic tube measurements are also comparatively costly and time‐consuming.AimsOur objective was to assess the best practice for using calibrated passive sampling in multi‐plot field trials. One particular challenge in such experiments is to evaluate the influence of ammonia drift between plots.MethodsIn a series of eight multi‐plot field trials, acid traps and DTM were used simultaneously on all plots to measure ammonia emissions caused by different slurry application techniques. Data obtained by both methods were correlated, and the influence of the ubiquitous ammonia background on both methods was evaluated by comparing net values, including the subtraction of the background with gross values (no background subtraction). Finally, we provide recommendations for calculating a TC for calibrating relative differences between plots, based on simultaneous acid trap and dynamic tube measurements on selected plots.ResultsTreatment mean values obtained by both methods correlated well. For most field trials, R2 values between 0.6 and 0.8 were obtained. Ammonia background concentrations affected both methods. Drift between plots contributed to the background for the acid traps, whereas the contamination of the chamber system might have caused the background for the DTM. Treatments with low emissions were comparatively more affected by that background.ConclusionFor a robust application of calibrated passive sampling, we recommend calculating the TC based on a treatment with high ammonia emissions, reducing the relative influence of the ubiquitous ammonia background.

AbstractBackgroundMany in‐person conferences were suspended during the initial stages of the COVID‐19 pandemic but have recently begun to return to in‐person or hybrid formats. However the incidence and severity of COVID‐19 infection during conferences, as well as behaviors at meetings associated with infection, are not well known.PurposeWe performed a targeted, systematic survey of self‐reported COVID‐19 infection and severity rates among in‐person attendees and potential attendees of a large national medical conference held in hybrid format during the during the Omicron subvariant wave, to provide guidance for future meeting attendees and organizers on COVID‐19 risk.MethodsA survey was sent to all members of the American Association of Physicists in Medicine (AAPM) as well as all attendees of the AAPM 2022 Annual Meeting (held July 10th–14th 2022 in Washington DC) with hybrid format) (total n = 10,627). The survey assessed relevant respondent demographics, views of COVID‐19 and in‐person meetings, COVID‐19 infection during the meeting or the following 7 days, and any COVID‐19 treatment received. Descriptive statistics and multivariable logistic regression with odds ratios (OR) and 95% confidence intervals (CI) were used for analysis.ResultsThe response rate was 13.7% (n = 1464) among the total invitees. Of respondents, 62.9% (n = 921) attended the meeting in person and 37.1% (n = 543) did not. Among in‐person meeting attendees, 82.1% (n = 756) attended indoor social events during the meeting including 67.5% (n = 509) who attended a large, AAPM‐coordinated social event. Reported COVID‐19 infection rates were higher among in‐person attendees (15.3%, n = 141) versus those that did not attend in‐person (6.1%, n = 33) (p < 0.001). Of those infected, 97.9% (n = 138) recovered entirely at home, with the remaining 2 (1.4%) undergoing emergency room visit without admission, and 1 (unvaccinated) individual (0.7%) reported hospital admission. On multivariable analysis of reported in‐person attendee behaviors, only attendance of the large, AAPM‐coordinated social event remained significantly associated with COVID‐19 infection (OR 2.8, CI 1.8–4.2, p < 0.001). Among in‐person attendees, 74.1% (n = 682) agreed that they would feel comfortable attending in‐person conferences in the future, 11.8% (n = 109) disagreed, and 14.0% (n = 129) neither agreed nor disagreed.ConclusionsDespite higher than previously reported COVID‐19 infection rates than prior studies, severity of infection was self‐limited with no hospitalizations among vaccinated attendees. In‐person attendees showed a willingness to return to large‐scale indoor social interaction, with a higher rate of COVID‐19 infection noted among those who attended a large conference‐affiliated social gathering. Most individuals reported feeling comfortable attending other in‐person meetings in the future.
