Published: January 2024

AbstractPotassium‐ion batteries (PIBs) have garnered significant attention as a promising alternative to commercial lithium‐ion batteries (LIBs) due to abundant and cost‐efficient potassium reserves. However, the large size of potassium ions and the resulting sluggish reaction kinetics present major obstacles to the widespread use of PIBs. Herein, we present a simple method to ingeniously encapsulate SnS2 nanoparticles within sulfurized polyacrylonitrile (SPAN) fibers (SnS2@SPAN) for serving as a high‐performance PIB anode. The large interlayer spacing of SnS2 provides a fast transport channel for potassium ions during charge–discharge cycles, while the one‐dimensional SPAN skeleton offers massive binding sites and shortens the diffusion path for potassium ions, facilitating faster reaction kinetics. Additionally, the excellent ductility of SPAN can effectively accommodate the large volume changes that occur in SnS2 upon potassium‐ion insertion, thereby enhancing the cyclic stability of SnS2. Benefiting from the above advantages, the SnS2@SPAN composites exhibit impressive cyclability over 500 cycles at 4 A g−1, with a capacity retention rate close to 100%. This study provides an effective approach for stabilizing high‐capacity PIB anode materials with large volume variations.
The ECB press conference statement: deriving a new sentiment indicator for the euro area
Authors: Kanelis Dimitrios , Siklos Pierre L. 
Published: January 2024

AbstractWe analyse the introductory statements of the ECB president and derive new sentiment indicators for the euro area based on a novel approach. To evaluate sentiment, we utilize a Large Language Model, namely FinBERT, which classifies the verbal sentiment of economics and finance‐related textual data. We find that the ECB's conveyed sentiment about monetary policy, which is influenced by the economic outlook and the state of the euro area macroeconomy as expressed in speeches, plays a significant role in shaping the content of press conferences following a governing council decision. In contrast, speech sentiment regarding financial stability does not significantly influence introductory statements.

Published: January 2024

AbstractFollowing successful treatment in which problem behavior is reduced, it may reemerge as a function of changes in contextual stimuli or the worsening of reinforcement conditions for an alternative response. Although understudied, preliminary research suggests that simultaneous changes in contextual stimuli and reinforcement conditions may represent particularly exigent treatment challenges that create the condition for additive or superadditive relapse. The purpose of the present review was to systematically examine the relapse literature involving simultaneous changes in contextual stimuli and reinforcement conditions in relapse tests and experimental preparations arranged to evaluate their effect on response recovery. We identified 16 empirical articles spanning 27 experiments. Although all experiments included at least one condition that experienced a change in contextual stimuli and worsening of alternative reinforcement conditions, only two experiments included the comparison conditions needed to precisely evaluate additive and superadditive relapse. Our findings establish the preclinical generality of relapse effects associated with simultaneous changes to reinforcement conditions and contextual stimuli across a range of subjects, schedule arrangements, response topographies, reinforcers, and types of contextual changes. We make several recommendations for future research based on our findings from this nascent and clinically relevant subdomain of the relapse literature.

AbstractA maximum temperature of 48.8°C (119.8°F) was purportedly recorded for the automated station in Siracusa (Syracuse) Contrada Monasteri, on the island of Sicilia (Sicily) Italy on August 11, 2021. A World Meteorological Organization (WMO) ad hoc evaluation committee was assembled to assess the possibility that the Sicilia temperature was the highest recorded temperature in WMO Region VI (continental only). After a detailed review of the site considerations and of the regional synoptic weather conditions, combined with detailed sensor testing and calibration by the Istituto Nazionale di Ricerca Metrologica (INRiM), the WMO evaluation committee concluded (and the Rapporteur accepted) that (1) on August 11, 2021 the high temperature recorded for the automated station in Siracusa C. da Monasteri, did reach a maximum value of 48.8°C (119.8°F), (2) that temperature is recommended to be listed as the WMO official “highest recorded temperature in WMO Region VI (continental only)” and (3) although, as the INRiM testing established, the recorded value of 48.8°C is actually an underestimate of the temperature, the committee recommend that the recorded (likely conservative) value of 48.8°C be the value listed in the Archive. An arbitrated archive of current weather and climate extremes is one means of ensuring that we have the best possible data for climate change analysis and public dissemination.
Effect of age, pregnancy, and tuberculosis status on oocyte parameters in African buffalo

Published: January 2024

AbstractIn the past decades, the African buffalo (Syncerus caffer) population has steadily declined; an estimated reduction of 31.2% over 3 generations has resulted in classifying it as near threatened by the International Union for Conservation of Nature. Therefore, the aim of this work was a preliminary evaluation of the size and number of ovarian follicles and oocyte quality and quantity in African buffaloes in relationship to age, tuberculosis, and pregnancy status to assess feasibility of in vitro embryo production (IVEP) as a tool for conservation and propagation of this species. The study occurred during the winter dry season (Jul–Aug) of 2018 within Huluhluwe‐Imfolozi National Park in Kwa‐Zulu Natal, South Africa during the routine culling procedures of African buffalo carried out at the park by the provincial authorities as means of disease management and population control. We obtained ovaries from 39 adults and 10 juveniles, and transported them to the field laboratory where we counted follicles, collected oocytes by aspiration and slicing, and classified oocytes according to their morphology. Adult animals had more small and medium follicles compared to juveniles (small: 14.5 ± 0.1 [SE] vs. 14.0 ± 0.1; medium: 4.6 ± 0.7 vs. 2.0 ± 1.3); however, juvenile animals had more cumulus‐oocyte complexes (COCs). Pregnancy and tuberculosis status did not affect COC recovery rate and quality. The oocyte recovery rate is comparable to cattle and higher than in water buffalo (Bubalus bubalis). Therefore, our results suggest that IVEP could be an effective tool for conservation of valuable germplasm in African buffalo. The use of aspiration, using an 18‐gauge needle and syringe, followed by slicing the ovary with a scalpel blade increased the recovery of suitable COCs (aspiration = 37.2 ± 3.02%; aspiration and slicing = 46.1 ± 3.02%), supporting the use of aspiration and slicing to optimize oocyte collection for conservation of African buffalo.

AbstractThe use of radiolabeled cells for positron emission tomography (PET) imaging tracking has been a promising approach for monitoring cell‐based therapies. However, the presence of free radionuclides released from dead cells during tracking can interfere with the signal from living cells, leading to inaccurate results. In this study, the effectiveness of the iron chelators deferoxamine (DFO) and deferiprone in removing free radionuclides 89Zr and 68Ga, respectively, was demonstrated in vivo utilizing PET imaging. The use of DFO during PET imaging tracking of 89Zr‐labeled mesenchymal stem cells (MSCs) significantly reduced uptake in bone while preserving uptake in major organs, resulting in more accurate and reliable tracking. Furthermore, the clearance of free 89Zr in vivo resulted in a significant reduction in radiation dose from 89Zr‐labeled MSCs. Additionally, the avoidance of free radionuclide accumulation in bone allowed for more precise observation of the homing process and persistence during bone marrow transplantation. The efficacy and safety of this solution suggest this finding has potential for widespread use in imaging tracking studies involving various cells. Moreover, since this method employed iron chelator drugs in clinical use, which makes it is a good prospect for clinical translation.

AbstractPosttraumatic stress disorder (PTSD) affects many military veterans. Given limited success of and barriers to conventional treatments, increasing interest is being paid to mind‐body therapy approaches. However, little evidence exists on whether these have the potential to treat traumatic stress. The aim of this study was to compare 6 months of hands‐on mind‐body therapy as an add‐on to treatment as usual (TAU) with TAU alone. Participants with PTSD resulting from active military service were randomly assigned to the intervention group or treatment‐as‐usual (TAU) group. The intervention group received 24 hands‐on manipulative mind‐body therapy sessions during 6 months as add‐on to TAU. The primary outcome was the PTSD Checklist‐Military version (PCL‐M) at 6 months (postintervention). Outcome measurements were obtained at four time points; baseline, 3 months (midway), 6 months (postintervention), and 12 months (follow‐up). Intention‐to‐treat analysis was done masked to allocation. A total of 42 participants were randomized (22 control, 20 intervention). In the intervention group, two discontinued the mind‐body therapy. At postintervention, participants who had received mind‐body treatment demonstrated greater reduction in PTSD severity (PCL‐M scores between‐group mean difference: −11.1, 95% CI −17.9 to −4.2, p = 0.002, effect size d = 1.06). At follow‐up, PCL‐M scores were not statistically significant between groups (between‐group difference: −4.65, 95% CI −11.8 to 1.50). Post hoc analysis showed that number of participants remitting from PTSD from baseline to follow‐up was 25% in the intervention group and 0% in the control group. Our study showed that hands‐on mind‐body therapy over 6 months produced clinically significant decrease in PTSD symptoms. The large reduction in symptoms was not maintained 6 months after the intervention period. Further research on mind‐body therapy as adjunctive PTSD treatment is warranted.

Published: January 2024

AbstractThis paper introduces a beam‐scanning holographic antenna composed of a substrate‐integrated waveguide (SIW) feeding structure and a rectangular microstrip array. The antenna innovatively combines holographic theory with liquid crystal electrical tunability to realize single‐frequency large‐angle beam scanning function which can effectively solve the problem of beamforming reconfiguration in traditional array antenna systems. In this paper, the variation of dielectric constant of liquid crystal under different bias voltages is quantitatively analyzed. Additionally, the beam forming technology is analyzed under hologram amplitude weighting theory. The relevant theories are verified by manufacturing and testing. The prototype antenna achieves the ultra‐wide beam scanning angle of −63° to 63° at 36 GHz.
Hybrid stress and heat‐flux formulation of thermodynamics for long‐term simulations in thermo‐viscoplasticity
Authors: Suljević Samir , Ibrahimbegovic Adnan , Dolarević Samir 
Published: January 2024

AbstractIn this article, we present a variational formulation for coupled problems in thermodynamics the most suitable for long‐term simulations of plastic behavior. We start with three‐field Hu–Washize variational formulation and perform regularization to include non‐symmetric stress, we thus recover the formulation that can accommodate any choice of discrete approximation. Such a regularized variational formulation allows us to eliminate the rotation field (as typically less important) and recover the corresponding hybrid stress format for equations of motion and transient heat conduction. The regularized variational formulation is further combined with discrete approximation based upon the Raviart–Thomas vector space for both mechanical and thermal fields, which enforces continuity across element boundaries for stress vector and normal component of heat‐flux. The conservation properties are validated with energy‐conserving scheme for thermoelastic behavior. The time integration of thermo‐viscoplastic behavior is carried out by energy‐decaying scheme to provide superior accuracy for computed stress in a long‐term simulation. The proposed approach offers higher computational robustness and results accuracy than the classical finite elements and time‐integration schemes. Such a performance is illustrated on several numerical simulations in non‐stationary problems for thermo‐viscoplastic behavior.

AbstractIntroductionDespite the high prevalence of sickle cell disease (SCD) in Brazil, no studies have described the validation of an SCD‐specific health‐related quality‐of‐life (HRQoL) instrument in children. We validated PedsQL 3.0 Sickle Cell Disease Module (PedsQL‐SCD) for Brazilian Portuguese, and cross‐validated it with PedsQL 4.0 Generic Core Scale (PedsQL‐GCS) in children with SCD.MethodsPedsQL‐SCD was translated and culturally adapted using forward and reverse translations. PedsQL‐SCD and PedsQL‐GCS were tested in children and adolescents with SCD aged 2–18 years and their caregivers. Validity was assessed using the Pearson and intraclass correlation coefficients, and reliability measured with Cronbach's alpha.ResultsPedsQL‐SCD was validated in 206 children with SCD (median age 14 years, range: 8–18) and 201 caregivers. Among patients and caregivers, the mean total score for PedsQL‐SCD was 65.7 and 64.1, respectively. The mean total score for PedsQL‐GCS was 73.1 and 68.9 among patients and caregivers, respectively. The internal consistency for PedsQL‐SCD and PedsQL‐GCS was good; Cronbach's alpha coefficients ranged from .59–.93 to .64–.83 among patients and from .60–.95 to .65–.85 among caregivers, respectively. Most intercorrelations between PedsQL‐SCD and PedsQL‐GCS, for patients and caregivers, had medium to large effect sizes (range: .23–.63 and .27–.64, respectively). Pain and pain impact domains of PedsQL‐SCD and physical dimension of PedsQL‐GCS had the highest cross‐correlation (.63 and .6 for patients; .63 and .64 for caregivers, respectively), confirming convergent construct validity.ConclusionPedsQL‐SCD is a valid, culturally appropriate measure to assess HRQoL in children with SCD in Brazil and is well‐correlated PedsQL‐GCS.

AbstractBackgroundThe rarity of childhood interstitial lung disease (chILD) makes it challenging to conduct powered trials. In the InPedILD trial, among 39 children and adolescents with fibrosing ILD, there was a numerical benefit of nintedanib versus placebo on change in forced vital capacity (FVC) over 24 weeks (difference in mean change in FVC % predicted of 1.21 [95% confidence interval: −3.40, 5.81]). Nintedanib has shown a consistent effect on FVC across populations of adults with different diagnoses of fibrosing ILD.MethodsIn a Bayesian dynamic borrowing analysis, prespecified before data unblinding, we incorporated data on the effect of nintedanib in adults and the data from the InPedILD trial to estimate the effect of nintedanib on FVC in children and adolescents with fibrosing ILD. The data from adults were represented as a meta‐analytic predictive (MAP) prior distribution with mean 1.69 (95% credible interval: 0.49, 3.08). The adult data were weighted according to expert judgment on their relevance to the efficacy of nintedanib in chILD, obtained in a formal elicitation exercise.ResultsCombined data from the MAP prior and InPedILD trial analyzed within the Bayesian framework resulted in a median difference between nintedanib and placebo in change in FVC % predicted at Week 24 of 1.63 (95% credible interval: −0.69, 3.40). The posterior probability for superiority of nintedanib versus placebo was 95.5%, reaching the predefined success criterion of at least 90%.ConclusionThese findings, together with the safety data from the InPedILD trial, support the use of nintedanib in children and adolescents with fibrosing ILDs.

AbstractIn this study, a novel series of 7‐[2‐(4‐substituted)‐2‐oxoethyl]amino‐4‐methyl‐2H‐1‐benzopyran‐2‐one derivatives (3 a‐f) were synthesized using 7‐amino‐4‐methyl coumarin and p‐substituted phenacyl bromides, and their pharmacological effects were examined. This reaction was carried out with potassium carbonate as a catalyst in dimethylformamide for 24 h at ambient temperature. The structures of synthesized compounds have been characterized by analysis using FTIR, NMR (1H and 13C) and Mass spectroscopic techniques, and their antibacterial, antidiabetic, and anti‐inflammatory properties have been explored. All synthesized compounds have exhibited good antibacterial activity against S. aureus, B. substilis, E. coli, and S. typhi.Compound 3 f shows maximum activity (zone of inhibition) at a 12 g/mL concentration compared to others. Compounds 3 c and 3 f showed excellent α‐amylase activity and had the lowest IC50 values for α‐glucosidase enzyme activities. The least IC50 value (12.42±0.27 g/mL) was demonstrated by the 3 e compound, which exhibited potent anti‐inflammatory activities. in silico Molecular docking studies suggested that compounds 3 f and 3 a interacted effectively with 4DO3: FAAH and 5DI1: MAP4 K4 proteins with good binding energies of −10.3 and −9.5 Kcal/mol, respectively.

Published: January 2024

AbstractDroplet microfluidics are extensively utilized to generate monodisperse cell‐laden microgels in biomedical applications. However, maintaining cell viability is still challenging due to overexposure to harsh conditions in subsequent procedures that recover the microgels from the oil phase. Here, a gravity‐oriented microfluidic device for end‐to‐end fabrication of cell‐laden microgels is reported, which integrates dispersion, gelation, and extraction into a continuous workflow. This innovative on‐chip extraction, driven by native buoyancy and kinetically facilitated by pseudosurfactant, exhibits 100% retrieval efficiency for microgels with a wide range of sizes and stiffnesses. The viability of encapsulated cells is perfectly maintained at ≈98% with minimal variations within and between batches. The end‐to‐end fabrication remarkably enhances the biocompatibility and practicality of microfluidics‐based cell encapsulation and is promising to be compatible with various applications ranging from single‐cell analysis to clinical therapy.
