AbstractMixed‐halide perovskites are considered the most straightforward candidate to realize blue perovskite light‐emitting diodes (PeLEDs). However, they suffer severe halide migration, leading to spectral instability, which is particularly exaggerated in high chloride alloying perovskites. Here, we demonstrate energy barrier of halide migration can be tuned by manipulating the degree of local lattice distortion (LLD). Enlarging the LLD degree to a suitable level can increase the halide migration energy barrier. We herein report an “A‐site” cation engineering to tune the LLD degree to an optimal level. DFT simulation and experimental data confirm that LLD manipulation suppresses the halide migration in perovskites. Conclusively, mixed‐halide blue PeLEDs with a champion EQE of 14.2 % at 475 nm have been achieved. Moreover, the devices exhibit excellent operational spectral stability (T50 of 72 min), representing one of the most efficient and stable pure‐blue PeLEDs reported yet.

AbstractDesigning adsorption materials with high adsorption capacities and selectivities is highly desirable for precious metal recovery. Desorption performance is also particularly crucial for subsequent precious metal recovery and adsorbent regeneration. Herein, a metal–organic framework (MOF) material (NH2‐UiO‐66) with an asymmetric electronic structure of the central zirconium oxygen cluster has an exceptional gold extraction capacity of 2.04 g g−1under light irradiation. The selectivity of NH2‐UiO‐66 for gold ions is up to 98.8 % in the presence of interfering ions. Interestingly, the gold ions adsorbed on the surface of NH2‐UiO‐66 spontaneously reduce in situ, undergo nucleation and growth and finally achieve the phase separation of high‐purity gold particles from NH2‐UiO‐66. The desorption and separation efficiency of gold particles from the adsorbent surface reaches 89 %. Theoretical calculations indicate that ‐NH2functions as a dual donor of electrons and protons, and the asymmetric structure of NH2‐UiO‐66 leads to energetically advantageous multinuclear gold capture and desorption. This adsorption material can greatly facilitate the recovery of gold from wastewater and can easily realize the recycling of the adsorbent.

Published: March 2023

SummaryA child with early failure of a Fontan circulation was listed for cardiac transplantation and then developed a subhepatic abscess. Surgical drainage was deemed necessary after the failure of an attempted percutaneous procedure. Following a multidisciplinary discussion, a laparoscopic technique was chosen to optimise postoperative recovery. To our knowledge, the literature does not describe any case of laparoscopic surgery in a patient with a failing Fontan circulation. This case report highlights the physiological variations involved with this management strategy, discusses the implications and risks, and offers some recommendations.
The territories of the practices of the trench: Origins, scope, desire
Authors: Tedesco Silvia , Cejas Gustavo 
Published: March 2023

AbstractOur work with children whose rights have been violated, with their families devastated by family violence and where the majority have been left out of the sociocultural systems and experiencing serious economic and educational difficulties, has taken us to our professional limit. The solitary and individual work, in the dim light of the office, left us without tools. As therapists, we can say that it has been necessary to break with our own mental schemes and to take a leap into the territory, the terrain itself. The learned university theories were questioned, forcing us to include a more humanising and less judgmental look at the work. A psychology of the trench was born for us. This paper articulates a work process that required something more than specific training in our subject matter. It summoned us as human beings capable of hosting suffering. From this starting point, and with an open mind and heart to go through its stages, this process is presented as a journey with advances and setbacks in its intervention modalities, systematising programs in permanent construction. Systematising practices is not an easy task. Familias Cuidando (Caring Families) and Adoptar es Posible (To Adopt is Possible) are the developmental spaces of our trench practices, practices that aim to accompany children, adolescents, and their families through the system of promotion and comprehensive protection of their rights. From Vicente López, a district in the province of Buenos Aires, our psycho‐socio‐educational and legal approach tries to be a link within collaborative and supportive practices; establishing ties, networks, and dialogues to strengthen the new paradigm aiming to support listening to the voice of children and adolescents; rescuing their childhoods, resignifying the different family models, and accompanying the construction of a life project for each one, in which we all fit.
Linear Diophantine equation (LDE) decoder: A training‐free decoding algorithm for multifrequency SSVEP with reduced computation cost
Authors: Mu Jing , Tan Ying , Grayden David B. , Oetomo Denny 
Published: March 2023

AbstractMultifrequency steady‐state visual evoked potentials (SSVEPs) have been developed to extend the capability of SSVEP‐based brain‐machine interfaces (BMIs) to complex applications that have large numbers of targets. Even though various multifrequency stimulation methods have been introduced, the decoding algorithms for multifrequency SSVEP are still in early development. The recently developed multifrequency canonical correlation analysis (MFCCA) was shown to be a feasible training‐free option to use in decoding multifrequency SSVEPs. However, the time complexity of MFCCA is shown to be
, which will lead to long computation time as
grows, where
represents the input size in decoding. In this paper, a novel decoding algorithm is proposed with the aim to reduce the time complexity. This algorithm is based on linear Diophantine equation solvers and has a reduced computation cost
while remaining training‐free. Our simulation results demonstrated that linear Diophantine equation (LDE) decoder run time is only one fifth of MFCCA run time under respective optimal settings on 5‐s single‐channel data. This reduced computation cost makes it easier to implement multifrequency SSVEP in real‐time systems. The effectiveness of this new decoding algorithm is validated with nine healthy participants when using dry electrode scalp electroencephalography (EEG).

Published: March 2023

AbstractBackgroundThe clinical diagnosis of behavioral variant frontotemporal dementia (bvFTD) in patients with a history of primary psychiatric disorder (PPD) is challenging. PPD shows the typical cognitive impairments observed in patients with bvFTD. Therefore, the correct identification of bvFTD onset in patients with a lifetime history of PPD is pivotal for an optimal management.MethodsTwenty‐nine patients with PPD were included in this study. After clinical and neuropsychological evaluations, 16 patients with PPD were clinically classified as bvFTD (PPD‐bvFTD+), while in 13 cases clinical symptoms were associated with the typical course of the psychiatric disorder itself (PPD‐bvFTD–). Voxel‐ and surface‐based investigations were used to characterize gray matter changes. Volumetric and cortical thickness measures were used to predict the clinical diagnosis at a single‐subject level using a support vector machine (SVM) classification framework. Finally, we compared classification performances of magnetic resonance imaging (MRI) data with automatic visual rating scale of frontal and temporal atrophy.ResultsPPD‐bvFTD+ showed a gray matter decrease in thalamus, hippocampus, temporal pole, lingual, occipital, and superior frontal gyri compared to PPD‐bvFTD– (p < .05, family‐wise error‐corrected). SVM classifier showed a discrimination accuracy of 86.2% in differentiating PPD patients with bvFTD from those without bvFTD.ConclusionsOur study highlights the utility of machine learning applied to structural MRI data to support the clinician in the diagnosis of bvFTD in patients with a history of PPD. Gray matter atrophy in temporal, frontal, and occipital brain regions may represent a useful hallmark for a correct identification of dementia in PPD at a single‐subject level.

AbstractBackgroundGiven the incurable nature of multiple myeloma (MM), efforts are made to improve the efficacy of anti‐CD38 monoclonal antibodies via combinations with other potentially synergistic therapies. This Phase 1/2 trial (NCT03194867) was designed to determine whether cemiplimab (anti‐PD‐1) enhances the anti‐myeloma activity of isatuximab (anti‐CD38) in patients with relapsed and refractory multiple myeloma (RRMM), to confirm the feasibility of the combination, determine its efficacy, and further evaluate its safety.MethodsPatients received isatuximab 10 mg/kg once weekly for 4 weeks followed by every 2 weeks (Isa), or isatuximab 10 mg/kg plus cemiplimab 250 mg every 2 (Isa + CemiQ2W) or every 4 weeks (Isa + CemiQ4W).ResultsOverall, 106 patients with RRMM treated with a median of 4 prior lines were included; 25.5% had high‐risk cytogenetics, 63.2% were refractory to proteasome inhibitors and immunomodulatory agents, 26.4% were previously exposed to daratumumab, and 84.0% were refractory to their last treatment line. There were no major changes in the safety or pharmacokinetic profile of isatuximab with the addition of cemiplimab. As assessed by investigators, four patients (11.8%) in the Isa arm, nine patients (25.0%) in the Isa + CemiQ2W arm, and eight patients (22.2%) in the Isa + CemiQ4W arm were responders. Though response rates were numerically higher in cemiplimab‐containing arms, differences were not statistically significant and did not translate to improved progression‐free or overall survival after a median follow‐up of 9.99 months.ConclusionOur results suggest a marginal benefit by adding cemiplimab to isatuximab, despite demonstration of target engagement, without additional observed safety issues.

Published: March 2023

AbstractGlycosidases are a type of enzyme that hydrolytically cleave carbohydrates and form glycans for biologically important processes. The inadequacies of glycosidases or their genetic abnormalities are responsible for various diseases. Thus, the development of glycosidase mimetics is of great importance. We have designed and synthesized an enzyme mimetic containing l‐phenylalanine, α‐aminoisobutyric acid (Aib), l‐leucine, and m‐Nifedipine. From X‐ray crystallography, the foldamer adopts a β‐hairpin conformation stabilized by two 10‐member and one 18‐member NH⋅⋅⋅O=C hydrogen bonds. Moreover, the foldamer was found to be highly efficient in hydrolysing ethers and glycosides in the presence of iodine at room temperature. Further, X‐ray analysis shows the backbone conformation of the enzyme mimetic to be almost unchanged after the glycosidase reaction. This is the first example of iodine‐supported artificial glycosidase activity with an enzyme mimic at ambient conditions.

Published: March 2023

AbstractJejunal diverticula are rare medical conditions with an incidence of 0.3%–2.5%, mostly discovered perioperatively. Our patient, 60 years old female, presented in an emergency with complaints of constipation, vomiting, abdominal pain, and distension. On examination, her abdomen was markedly distended with generalized tenderness. An erect abdominal X‐ray revealed multiple air‐fluid levels, which suggests small bowel obstruction. A diagnosis of jejunal diverticula was made on exploratory laparotomy. No evidence of granuloma or malignancy was seen on histopathological examination. Segmental resection of the affected jejunum was carried out, followed by end‐to‐end primary anastomosis. The patient was discharged on postoperative Day 6 with complete recovery at 2 weeks follow‐up visit.

Published: March 2023

AbstractEfficiency and stability are key factors determining the final cost of electricity that perovskite solar cells (PSCs) generate. To date, effective strategy to progress in achieving efficient and stable PSCs is still a difficult problem that researchers continue to explore. This study reports a useful way to improve the quality of SnO2 film by introducing potassium citrate (PC) into SnO2 nanoparticles solution. PC passivates interface defects between perovskite and SnO2 layers via the interactions of functional groups (K+, −COO−) in PC with undersaturated Pb and I ions in perovskite and Sn4+ in SnO2. The resultant photovoltaic (PV) device achieves a champion power conversion efficiency (PCE) of 22.79 %. The introduction of PC interface also significantly suppress the degradation of PSCs, by which 87.6 % of initial PCE is maintained after 2850 h storage in ambient environment. Moreover, the devices retained 95.5 % of initial PCE under 1‐sun continuous illumination for 1000 h.

Published: March 2023

AbstractAt the beginning of his youthful sixth decade, this work is dedicated to Prof. Dr. Fabio Doctorovich. He is distinctive in organometallic chemistry. During his successful career, he has been studying the reactivity and application of metalloporphyrins. Metalloporphyrins are organometallic complexes that exhibit, through synthetic modifications, the ability to tune their optical and electrochemical properties and their selectivity towards a particular molecule or ion. For this reason, they are systems extremely useful as electrochemical sensors to detect and quantify a wide variety of analytes with high selectivity, even in real samples such as food, water, biological fluids, or pharmaceutical compounds. This review presents an up‐to‐date list of reports in which metalloporphyrins are used as electrochemical sensors. In addition to compiling a comprehensive and up‐to‐date list of reported sensors that utilize metalloporphyrins, this work aims to provide an overview of currently available tools and techniques for the detection of various chemical species through similar approaches, which are constantly being developed.

AbstractIndustrial‐scale metal mining has long been a feature of developing economies. Processing ores to recover minerals has generated large quantities of waste rock, tailings and contaminants. Mining‐related deposits, along with associated soil and water geochemistry, river modifications and other environmental changes, are a product of the nature, scale and intensity of past operations. These artefacts of historical mining create anthropogenic landscapes that extend far beyond individual sites due to the dispersal of mine waste by rivers and pose enduring threats to human and ecosystem health. Their presence and significance, however, are often overlooked by heritage and environmental managers. To be acknowledged as artefacts of the historical mining industry, landscape features must be identified and characterised with reference to the human activities that triggered their formation. This requires an interdisciplinary approach that incorporates anthropogenic landscape change at a regional scale. In this paper, we integrate archaeological, geomorphological and geochemical evidence to identify and analyse mining‐related changes to the Loddon River valley in Victoria, Australia. Nineteenth‐century gold mining caused extensive erosion of creeks and gullies and mobilised sediments that filled channels and spread over floodplains. In addition, tailing deposits concentrated arsenic at levels significantly above environmental background conditions. Recognising these legacies of historical mining is vital to understanding mining heritage and to managing healthy rivers, environments and communities.
Distributional effects of perceptional financial scarcity and abundance on food choices
Authors: Huseynov Samir , Palma Marco A. , Segovia Michelle 
Published: March 2023

AbstractThis article enriches the attribute‐based choice literature in economics by providing compelling evidence that inducing perceptional financial scarcity and abundance affects consumer food choices. Our experiment shows that induced financial scarcity reduces the likelihood of purchasing high‐quality low‐calorie food items at a price premium. We also find that income is an important factor that moderates this effect. The low‐income group demonstrates similar purchasing behaviors in the Scarcity and Abundance experimental conditions. However, the high‐income group is more likely to respond to perceptional financial changes.
On the crucial features of a single‐file transport model for ion channels
Authors: Liang Kuo Kan 
Published: March 2023

AbstractIt has long been accepted that the multiple‐ion single‐file transport model is appropriate for many kinds of ion channels. However, most of the purely theoretical works in this field did not capture all of the important features of realistic systems. Nowadays, large‐scale atomic‐level simulations are more feasible. The discrepancy between theories, simulations, and experiments are getting obvious, enabling people to carefully examine the missing parts of the theoretical models and methods. In this work, it is attempted to find out the essential features that such kinds of models should possess, such that the physical properties of an ion channel be adequately reflected.

AbstractThe biogenic synthesis of silver nanoparticles (AgNPs) is an important step in developing eco‐friendly and environmentally stable tools for ameliorating crop growth. In the current study, AgNPs were synthesized using Funaria hygrometrica and characterized using ultraviolet (UV) spectroscopy, scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, and X‐ray diffraction (XRD). The UV spectrum showed an absorption peak at 450 nm. SEM revealed an irregular and spherical morphology, FTIR spectroscopy indicated the presence of various functional groups, while XRD displayed peaks at 45.24°, 38.17°, 44.34°, 64.54°, and 57.48° 2θ. The effects of the F. hygrometrica‐mediated AgNPs on maize growth and germination were assessed at 0, 100, 300, and 500 ppm. The germination percentage and relative germination rate were increased to 95% ± 1.83% and 100% ± 2.48% at 100 ppm of synthesized AgNPs and then declined at 300 and 500 ppm. The length, fresh weight, and dry matter of the root, shoot, and seedlings were highest at 100 ppm NPs. The plant height, root length, and dry matter stress tolerance indices were also the highest (112.3%, 118.7%, and 138.20% compared with the control) at 100 ppm AgNPs. Moreover, the growth of three maize varieties, that is, NR‐429, NR‐449, and Borlog, were assessed at 0, 20, 40, and 60 ppm F. hygrometrica‐AgNPs. The results indicated the highest root and shoot length at 20 ppm AgNPs. In conclusion, seed priming with AgNPs enhances the growth and germination of maize and can ameliorate crop production globally.Research Highlights
