Published: February 2025

AbstractPhosphine‐ or carbene‐based soft ligands are customarily used in Rh and other late transition metal catalyzed alkene and alkyne hydrosilylation and hydrogenation. We report here an aziridine and a 2‐pyrrolidone with pyridyl sidearms, whose cationic Rh(I) complexes prove as excellent catalysts for hydrosilylating terminal olefins by Et3SiH giving anti‐Markovnikov products selectively. To the best of our knowledge, the [(2‐pyrrolidone)‐Rh]+ seems to be the most active Rh catalyst recording a highest TOF of 24000 h‐1. It works remarkably (TOF: 714 h‐1) even at 10 ppm concentration! Terminal alkynes are hydrosilylated too to give β‐(Z)‐vinylsilanes selectively. Both catalysts also hydrogenate alkenes and doubly‐hydrogenate alkynes, both terminal and internal, under ambient and benchtop conditions. But in hydrogenation, the [(aziridine)‐Rh]+ catalyst works better. Both ligands and the Rh catalysts are air‐stable.

Published: February 2025

Comprehensive SummaryChiral perovskites provide an ideal platform for the construction of linear and nonlinear optical materials due to their diverse chemical variability, structural tunability, and intrinsic non‐centrosymmetricity which have broad application prospects for next‐generation optoelectronic devices. In this work, a pair of 1D chiral lead halide perovskites (R/S‐4MeOPEA)PbCl3 (4MeOPEA = (4‐methoxyphenyl)ethylamine) were synthesized, and characterized systematically. Crystal structure analysis revealed that the one‐dimensional (1D) inorganic chain formed by face‐shared lead chloride octahedra was separated by the chiral organic spacers. The distorted octahedra endows them with broadband bluish‐white light emission centered covering the range 350—700 nm with a width of 104 nm. In addition, the highly anisotropic second‐harmonic generation (SHG) with a near unity polarization ratio was observed. This work presents a fresh example of 1D chiral perovskite with exotic linear and nonlinear optical properties, which could provide a new footstone for further optoelectronic devices.
Susceptible‐infected‐recovered model with stochastic transmission
Authors: Gouriéroux Christian , Lu Yang 
Published: February 2025

AbstractThe susceptible‐infected‐recovered (SIR) model is the cornerstone of epidemiological models. However, this specification depends on two parameters only, which results in its lack of flexibility and explains its difficulty to replicate the volatile reproduction numbers observed in practice. We extend the standard SIR model to a semiparametric SIR model, by first introducing a functional parameter of transmission, and then making this function stochastic. This leads to a SIR model with stochastic transmission. Our model is particularly tractable. We derive its closed‐form solution and use it to compute key indicators, such as the condition (and the threshold) of herd immunity and the timing of the peak. When the population size is finite and the observations are in discrete time, there is also observational uncertainty. We propose a nonlinear state‐space framework under which we analyze the relative magnitudes of the observational and intrinsic uncertainties during the evolution of the epidemic. We emphasize the lack of robustness of the notion of herd immunity when the SIR model is time‐discretized.
Balanced longitudinal data clustering with a copula kernel mixture model
Authors: Zhang Xi , Murphy Orla A. , McNicholas Paul D. 
Published: February 2025

AbstractMany common clustering methods cannot be used for clustering balanced multivariate longitudinal data in cases where the covariance of variables is a function of the time points. In this article, a copula kernel mixture model (CKMM) is proposed for clustering data of this type. The CKMM is a finite mixture model that decomposes each mixture component's joint density function into a copula and marginal distribution functions. In this decomposition, the Gaussian copula is used due to its mathematical tractability and Gaussian kernel functions are used to estimate the marginal distributions. A generalized expectation‐maximization algorithm is used to estimate the model parameters. The performance of the proposed model is assessed in a simulation study and on two real datasets. The proposed model is shown to have effective performance in comparison with standard methods, such as ‐means with dynamic time warping clustering, latent growth models and functional high‐dimensional data clustering.

Published: February 2025

AbstractBackgroundSymptomatic Dermographism (SD), also known as “urticaria factitia”, is the most common subtype of chronic inducible urticaria. Affected patients develop itch and strip‐shaped wheals that usually last for 30 min after minor stroking, rubbing, or scratching of the skin. The quality of life (QoL) of patients with SD is often strongly affected. However, a QoL instrument to properly assess this impairment is not yet available.ObjectiveThe aim of this study was to develop the first disease‐specific patient reported outcome measure|patient reported outcome measures (PROM) to evaluate QoL impairment in SD patients, the Symptomatic Dermographism Quality of Life Questionnaire (SD‐QoL).MethodsSD‐QoL was developed following current guidelines for PROM development. We first generated a hypothetical conceptional framework of the SD‐QoL, followed by an item generation and an item selection/reduction phase.ResultsDuring the item generation phase, 69 potential items of the SD‐QoL were generated by applying a combined approach consisting of literature review, expert input as well as semi‐structured interviews with affected patients. During the item selection phase, we reduced this long list of items to a final 13‐item set by means of impact analysis, inter‐item correlation, and additional criteria for item reduction, including an expert review for content (face) validity. Finally, a US‐American‐English version of the SD‐QoL was developed using a structured translation process.Conclusions and Clinical RelevanceThe SD‐QoL is the first disease‐specific‐QoL instrument for SD with a recall period of 7 days that allows the assessment of QoL in SD patients. A subsequent validation study will determine its validity and reliability.

Published: February 2025

ABSTRACTObjectivesBorderline personality disorder (BPD) and eating disorders (EDs) are common comorbid diagnoses. Given the various combinations of borderline personality disorder symptoms (BPDS) that can comprise a diagnosis, understanding whether specific BPDS are more likely to be associated with an ED (anorexia nervosa [AN], bulimia nervosa [BN], and binge eating disorder [BED]) is important for the conceptualization and treatment of BPD‐ED comorbidity.MethodsThis study used data from the National Epidemiologic Survey on Alcohol and Related Conditions‐III (NESARC‐III) study, a nationally representative dataset of US adults (N = 36,309). The association of BPDS with EDs, compared with psychiatric and healthy control groups, was examined in two binomial and two multinomial (i.e., with all ED diagnoses) models.ResultsCompared with the healthy control group, affect instability, emptiness, impulsivity, self‐injurious behaviors, and unstable relationships were positively associated with any ED diagnosis (AN, BN, or BED). Compared with the psychiatric control group, impulsivity was positively associated with any ED diagnosis. In the multinomial model with the healthy control group, impulsivity and self‐injurious behaviors were positively associated with AN, BN, and BED, emptiness was positively associated with AN and BED, and unstable relationships and affect instability were positively associated with BED. In the multinomial model with the psychiatric control group, self‐injurious behaviors were positively associated with AN, and impulsivity and affect instability were positively associated with BED.DiscussionResults suggest certain BPDS may be more common with certain EDs (AN, BN, and BED), even when controlling for other EDs and a psychiatric control group.

ABSTRACTObjectiveParents of children diagnosed with anorexia nervosa (AN) are facing multiple burdens when caring for their child. This study uses a psychological network approach to identify central factors among parental caregiving burdens and experiences which then can constitute promising targets for caregiver interventions.MethodA total of 348 parents (247 mothers, 101 fathers) of children diagnosed with AN (96% female, 90% restrictive type) provided data including parental psychopathology, eating‐disorder related burden, high‐expressed emotion and perceived caregiver skills at baseline and after having participated in a parental skills training, multi‐family therapy or systemic family therapy. Regularized partial correlation networks including 14 variables were estimated for baseline and follow‐up data were estimated.ResultsHigh‐expressed emotion, particularly parental emotional overinvolvement emerged as the most central variable in the network showing substantial correlations with depression and low self‐care behavior. Emotional overinvolvement also functioned as a bridge variable between parental psychopathology, perceived caregiver skills, and eating disorder‐related burden. Moreover, parental criticism was strongly associated with burden due to the child's confrontational behavior and low levels of parental frustration tolerance. Network comparison tests neither revealed statistically significant differences in network structure and global network strength between baseline and follow‐up, nor between mothers and fathers.DiscussionThis study highlights the importance of parental high‐expressed emotion as a promising treatment target. Adding or intensifying intervention components promoting parental emotion regulation strategies as well as intensified training in Motivational Interviewing may be useful therapeutic approaches to decrease overall parental burden.

ABSTRACTPseudotsuga sinensis is a distinctive plant species endemic to China, predominantly found in areas affected by varying degrees of rocky desertification. Despite its wide distribution, the physiological mechanisms underlying its adaptation to harsh environments remain unclear. In this study, we investigated 16 leaf traits, including the morphological, anatomical, and chemical characteristics of the leaves of P. sinensis across forests with mild, moderate, severe, and extremely severe rocky desertification to elucidate the adaptive strategies of P. sinensis in response to arid conditions and nutrient‐poor soils. Our findings revealed that P. sinensis leaves from forests with mild and moderate rocky desertification exhibited higher specific leaf area (SLA) and magnesium concentrations but lower leaf dry matter content (LDMC), abaxial epidermis thickness, and adaxial epidermis thickness than in those from forests with severe and extremely severe desertification. Principal component analysis indicated that forests with mild to moderate desertification employ resource acquisition strategies characterized by greater SLA and magnesium concentrations than those in forests with severe and extremely severe desertification. In contrast, forests with severe to extremely severe desertification adopted resource‐conserving strategies, as evidenced by higher LDMC, epidermal thickness, and calcium concentrations than those in forests with mild to moderate desertification. The N:P ratio of P. sinensis across all desertification levels was consistently below 14, suggesting nitrogen limitation in P. sinensis in regions with rocky desertification. Thus, these results provide valuable reference for guiding vegetation restoration under degraded habitats.

Published: February 2025

ABSTRACTBeach mass stranding events of marine organisms, widely documented worldwide, are triggered by a range of biotic and abiotic environmental factors, often unexplained. Such occurrences among pelagic crustaceans are less frequent, yet not uncommon. Here we studied mass mortality events of hyperiid amphipods—abundant members of pelagic zooplankton, commonly associated with gelatinous organisms. Our study examined consecutive mass die‐off and stranding events of free‐living hyperiids in the Red Sea during 2023 and 2024. We investigated three potential causes: semelparous reproduction, thermal stress, and physical oceanographic conditions. To place our findings in a broader context, we further performed a global review of hyperiid swarming and mass mortality events from scientific literature and a citizen science repository. Morphological and molecular analyses confirmed that the hyperiid species in the die‐off events at the Red Sea was Anchylomera blossevillei (Phrosinidae). The balanced male: female sex ratio (0.99), combined with the absence of gravid or brooding females, led to the rejection of semelparity as a driving factor. The environmental data did not indicate thermally stressful conditions, and no evidence of parasitic infection was found. Nonetheless, previous studies have shown that under weak wind conditions, as measured during the stranding events, coherent cyclonic eddies with diameters of 5–6 km are developed in the northern Gulf of Aqaba, persisting for about a day. These eddies can exceed velocities of 100 cm s−1 and may have facilitated the hyperiid stranding events. Future research should unveil the impacts of such events on marine ecosystems.

Further, the present study also revealed that L. hatsudake contains high antioxidant potential.
Synthesis of Esters Using Modified Waste Copper Slag: A Sustainable Approach for Waste Valorisation
Authors: Megha Bhagyashree , More Pavan 
Published: February 2025

ABSTRACTThe active sites of waste copper slag were moulded using BaO and used as a catalyst for the esterification reaction without solvent. Various concentrations of BaO were doped over the copper slag and investigated for the esterification of various model components of flavour, fragrance and biofuel. The catalyst was characterised by X‐ray photoelectron spectroscopy, attenuated total reflectance‐Fourier transform infrared spectroscopy, surface area analysis and X‐ray diffraction to examine the impact of BaO addition on the structural and morphological characteristics of BaOX/Cp‐Sl. BaO increases the grain size and enhances the BaOX/Cp‐Sl catalyst's activity and selectivity to flavour, fragrance and biofuel. The BaO2.5%/Cp‐Sl catalyst showed the maximum conversion of oleic acid to the methyl ester. The esterification of various commercially important substrates like geraniol, citronellol, menthol, isoamyl acetate, palmitic acid and waste cooking oil using a catalyst has been explained in detail. The kinetic study of the esterification has been explained with turnover number (TON) and turnover frequency (TOF). The mechanism pathway of the catalyst with various active sites of waste copper slag has been explained using adsorption studies.
The Influence of a Dementia Diagnosis on Clinical Decision‐Making in Dysphagia Management
Authors: Van Sickle Angela J. , Bice Ed M. 
Published: February 2025

ABSTRACTObjectivesThe main objective of this survey was to determine the effects of a dementia diagnosis on dysphagia management by speech‐language pathologists (SLP).MethodsA survey of SLPs interested and/or working with individuals with dysphagia was conducted via a website. The SLPs viewed two written cases of patients with dysphagia, one with dementia and one without dementia. Both cases included a video capture of the patients' swallows. SLPs answered specific questions related to each case and video.ResultsFrequency counts, McNemar's Test, and descriptive analysis of responses showed that participants were less likely to initiate dysphagia therapy (p < 0.001) or use rehabilitative swallowing strategies (p = 0.008) for individuals with dysphagia and a dementia diagnosis than for an individual with dysphagia without a dementia diagnosis. In addition, SLPs overidentified impairments and chose treatment targets not present.ConclusionsBased on the current survey, SLPs displayed a bias when the diagnosis of dementia was present. The bias appears to exist regardless of experience or education. Not initiating treatment or not providing rehabilitative strategies may have detrimental effects on the health and quality‐of‐life of individuals with dementia.

AbstractObjectiveTo analyze the rate of vaginal cuff dehiscence (VCD) by surgical approach and surgeons' experience.MethodIn this observational, retrospective, cohort study, rates of VCD were calculated based on surgical approach, and VCD clinical characteristics were analyzed. Surgical routes of laparotomy, laparoscopy, and robotic surgery were compared. All minimally invasive surgeries were performed or supervised by a Japanese Society of Gynecology Obstetrics Endoscopy‐certified laparoscopic surgeon.ResultsThere were 4864 hysterectomies in total: abdominal hysterectomies (n = 2578, 53.0%), laparoscopic hysterectomies (n = 1840, 37.8%), and robotic hysterectomies (n = 446, 9.2%). Among the 20 (0.411%) patients with VCD, the rate of VCD was highest for laparoscopic hysterectomy (0.706%), followed by robotic surgery (0.224%) and laparotomy (0.233%). Most causes of VCD were due to intercourse (50%), but 8 of 9 (88.8%) cases caused spontaneously or by defecation were laparoscopic cases. Defecation‐related and spontaneous cases occurred significantly earlier after surgery than did intercourse‐related cases (P = 0.008).ConclusionOur data showed a decrease in laparoscopic VCD compared with those of previous reports. VCD occurred more frequently with laparoscopy than with laparotomy, even when performed by experienced surgeons. Laparoscopic VCD often develops early with little external force applied. Problems with vaginal stump rigidity may be related to the surgical procedure.

Published: February 2025

ABSTRACTA solid‐state laser is preferred for generating light in a photoacoustic (PA) system because of its high energy and coherence. However, conventional Nd:YAG lasers are bulky, complex, and expensive. This article introduces a portable alternative: a custom‐built Nd:YAG laser with an in‐house power supply that delivers 0–30 A current pulses with a 1500 μs pulse width, providing efficient thermal management. A pockels cell driver generates 10 ns pulses with 3.84 mJ/cm2 laser energy density. Implemented for noninvasive breast cancer diagnosis, The peak frequency obtained from three different samples was 0.23 ± 0.1, 0.26 ± 0.13, and 1.80 ± 0.14 MHz, respectively, for Normal, Fibrotic, and Tumor tissues. In addition to the dominant frequency peaks the spectral energy of the PASR spectra has also been investigated to characterize the breast tissue samples. The developed laser successfully differentiates between carcinoma, fibrocystic disease, and normal breast tissue based on quantitative PA spectral parameters.

ABSTRACTThis study aims to investigate the phenomenon of human papillomavirus (HPV) genotype switching (HGS), assess the potential influencing factors, and evaluate the clinical impact on the severity of cervical lesions. A total of 2569 HPV positive female patients with records of more than two follow‐up visits were included from the gynecology department at the Obstetrics and Gynecology Hospital of Fudan University, covering the period from May 2012 to September 2022. Patients' age, treatments, vaccination, HPV genotypes before and after HGS, and the final pathology results from colposcopy were recorded. Multifactorial analyses and correlation tests were performed. Single HPV infections accounted for 67% of the total population, while multiple HPV infections comprised 33%. The most prevalent genotypes in single HPV infections were HPV52 (18.6%), HPV16 (12.28%), HPV58 (11.72%), HPV53 (8.63%), and HPV81 (6.81%). Among cases of multiple infections, the most common genotype combinations were HPV52 + HPV53 (3.02%), HPV52 + HPV58 (3.13%), and HPV52 + HPV81 (3.02%). HGS was detected in 38.2% of the total cases (458/1200). The status of medication treatment was not found to correlate with the occurrence of HGS. However, age, surgical treatment status, vaccination status, and the genotype of HPV infection may be correlated with HGS. HPV52, HPV58, HPV53, HPV56, and HPV81 showed a positive association with the occurrence of HGS transitioning from multiple infections to a single infection (HGS‐MS) (p < 0.05). In contrast, HPV52, HPV16, HPV58, HPV39, HPV56, and HPV18 significantly influenced the occurrence of HGS from one single infection to another (HGS‐SS) (p < 0.05), albeit negatively. Notably, only one type of HGS, HGS‐MS, demonstrated a positive correlation with the severity of cervical lesions. Our findings suggest that HPV genotype switching from multiple infections to single infections is associated with cervical intraepithelial neoplasia (CIN). Different patterns of HGS could result from specific HPV genotype infections, particularly HPV16. HGS‐MS is revealed to plays a catalytic role in the progression of cervical lesions.
