AbstractMagnetic resonance imaging (MRI)/magnetic resonance spectroscopy (MRS) employing proton nuclear resonance has emerged as a pivotal modality in clinical diagnostics and fundamental research. Nonetheless, the scope of MRI/MRS extends beyond protons, encompassing nonproton nuclei that offer enhanced metabolic insights. A notable example is phosphorus‐31 (31P) MRS, which provides valuable information on energy metabolites within the skeletal muscle and cardiac tissues of individuals affected by diabetes. This study introduces a novel double‐tuned coil tailored for 1H and 31P frequencies, specifically designed for investigating cardiac metabolism in rabbits. The proposed coil design incorporates a butterfly‐like coil for 31P transmission, a four‐channel array for 31P reception, and an eight‐channel array for 1H reception, all strategically arranged on a body‐conformal elliptic cylinder. To assess the performance of the double‐tuned coil, a comprehensive evaluation encompassing simulations and experimental investigations was conducted. The simulation results demonstrated that the proposed 31P transmit design achieved acceptable homogeneity and exhibited comparable transmit efficiency on par with a band‐pass birdcage coil. In vivo experiments further substantiated the coil's efficacy, revealing that the rabbit with experimentally induced diabetes exhibited a lower phosphocreatine/adenosine triphosphate ratio compared with its normal counterpart. These findings emphasize the potential of the proposed coil design as a promising tool for investigating the therapeutic effects of novel diabetes drugs within the context of animal experimentation. Its capability to provide detailed metabolic information establishes it as an indispensable asset within this realm of research.
Injury and recovery process of intestine caused by okadaic acid and related compounds
Authors: Ito Emiko , Terao Kiyoshi 
Published: September 2023

AbstractThe injuries and repair processes in the intestines of mice induced by dinophysistoxin 3 (DTX 3) were compared morphologically to those induced by okadaic acid (OA) and dinophysistoxin 1 (DTX 1). DTX 3 impaired intestinal villi by the oral route only, whereas OA and DTX 1 caused intestinal injury with both oral and intraperitoneal exposures. The character of the lesions caused by the 3 toxins and the recovery processes were highly similar. Within 5 min of dosing, the basal portion of the covering epithelium became homogeneous and peeled from the lamina propria, while the upper portion containing microvilli remained intact. There were two types of villous injury and recovery: 1) When the injuries were limited to the villi, new cells from the crypts moved upward and differentiated into columnar cells. 2) When injuries progressed into the glands of Lieberkuhn, clusters of crypt cells were exposed to the intestinal lumen, and in the most severe case they were completely separated. Villous fusion was often seen in the recovery process of the type 2 cases. Recovery from the injuries was almost completed within 2 days. When mice were pretreated with fusarenon‐X, a mycotoxin which injures undifferentiated crypt cells preferentially, the injury induced by OA to the intestinal crypts was exacerbated and the recovery was delayed.

AbstractA molecular mechanics study of cyclophosphazenic polypodands and of glymes, of their complexes with ion pairs (IPs) M+ I− (M+ = Li+, Na+, K+, Rb+) and IP aggregates (M+ I−)n was carried out to investigate the catalytic activity of these ligands in solid–liquid phase‐transfer reaction. This activity is explained by their ability to bind IP aggregates effectively and to activate the anion by increasing the interionic distance in the single IP.

Published: September 2023

AbstractEmploying the multiple Davydov D2 Ansätze with the time‐dependent variational principle, photon‐assisted Landau–Zener (LZ) transitions and qubit manipulation in a hybrid quantum electrodynamics device have been investigated. Modeled as a Rabi dimer, the device comprises of two interacting transmission‐line resonators, each coupled to a qubit. The qubits, driven by independent harmonic fields, are further modulated by a micromechanical resonator mimicked by a phonon mode. The impacts of two independent driving fields on the qubit dynamics are carefully examined. The energy diagram of the system and the photon number mobilization on the resonators are analyzed to explain the behavior of the LZ transitions and qubit dynamics while taking into account the influence of the single phonon mode. Results show that low phonon frequencies can alter the qubit dynamics, particularly in the absence of the driving fields, and a strong phonon coupling strength can significantly perturb the qubit dynamics, thanks to a high influx of phonon energy. Notably, only the photon frequency affects the oscillation frequency of qubit polarization. This study unveils the imperative roles that photons and phonons play in the Rabi dimer model.
A single‐input single‐output versus multiple‐input multiple‐output feedback controllers for the Korteweg‐de Vries‐Kuramoto‐Sivashinsky equation
Authors: Smaoui N. , Al Jamal R. 
Published: September 2023

SummaryThe dynamics and control of the Korteweg‐de Vries‐Kuramoto‐Sivashinsky (KdVKS) equation subject to periodic boundary conditions are considered. First, the dynamics of the KdVKS equation is analyzed using the Fourier Galerkin reduced‐order method. This reduced‐order method is used to generate a finite‐dimensional approximation of the KdVKS equation. Then, a multiple‐input multiple‐output (MIMO) and a single‐input single‐output (SISO) controllers are designed to stabilize the finite‐dimensional approximation of the linearized KdVKS equation. We show that both the MIMO and SISO controllers which are designed to stabilize the linearized system will locally stabilize the infinite‐dimensional KdVKS equation. The Frechét differentiability of the semigroup generated by the closed‐loop system is crucial to prove the local stability results of the controllers. Furthermore, we show that the condition on the number of output measurements that must equal to the total number of unstable and critically stable eigenvalues of the linearized KdVKS equation is not necessary for the local exponential stability of the KdVKS equation. Finally, numerical simulations based on the two designed controllers are presented and compared to illustrate the developed theory.

AbstractAlthough antibiotic is still the main choice for antibacteria both in hospital and community, phototherapy has become a possibly one of the alternative approaches in the treatment of microbe‐associated infections nowadays because of its considerable potential in effective eradication of pathogenic bacteria. However, overwhelming reactive oxygen species (ROS) generated from phototherapy inevitably provoke an inflammatory response, complicating the healing process. To address this outstanding issue, a MXene‐decorated nanofibrious is devised that not only yield localized heat but also elevate ROS levels under near‐infrared laser exposure ascribed to the synergistic photothermal/photodynamic effect, for potent bacterial inactivation. After being further loaded with aspirin, the nanofibrous membranes exhibit benign cytocompatibility, boosting cell growth and suppressing the (nuclear factor kappa‐B ( NF‐κB) signaling pathways through RNA sequencing analysis, indicating an excellent anti‐inflammatory effect. Interestingly, in vivo investigations also corroborate that the nanofibrous membranes accelerate infectious cutaneous regeneration by efficiently killing pathogenic bacteria, promoting collagen deposition, boosting angiogenesis, and dampening inflammatory reaction via steering NF‐κB pathway. As envisaged, this work furnishes a decorated nanofibrous membrane with programmed antibacterial and anti‐inflammatory effects for remedy of refractory bacteria‐invaded wound regeneration.

AbstractIn the search for sustainable cathode materials for aqueous zinc ion batteries (AZIBs), vanadium (V)‐based materials have garnered interest, primarily due to their abundance and multiple oxidation states. Among the contenders, Li3VO4 (LiVO) stands out for its affordability, high specific capacity, and elevated ionic conductivity. However, its limited electrical conductivity results in significant resistance polarization, limiting its rate capability, especially under high currents. Through density functional theory (DFT) calculations, this study evaluates the electrochemical implications of carbon (C) incorporation within the LiVO matrix. The findings indicate that C integration significantly ameliorates the conductivity of LiVO. Moreover, C serves as a barrier, mitigating direct interactions between Zn2+ and LiVO, which in turn expedites Zn2+ diffusion. When considering various C materials for this role, glucose is emerged as the optimal candidate. The LiVO/C‐glucose composite (LiVO/C‐G) is observed to undergo dual phase transitions during charge–discharge cycles, resulting in an amorphous vanadium‐oxygen (VO) derivative, paving the way for subsequent electrochemical reactions. Collectively, the insights pave a promising avenue for refining AZIB cathode design and performance.

AbstractHosts hold great prospects for addressing the dendrite growth and volume expansion of the Li metal anode, but Li dendrites are still observable under the conditions of high deposition capacity and/or high current density. Herein, a nitrogen‐doped graphene mesh (NGM) is developed, which possesses a conductive and lithiophilic scaffold for efficient Li deposition. The abundant nanopores in NGM can not only provide sufficient room for Li deposition, but also speed up Li ion transport to achieve a high‐rate capability. Moreover, the evenly distributed N dopants on the NGM can guide the uniform nucleation of Li so that to inhibit dendrite growth. As a result, the composite NGM@Li anode shows satisfactory electrochemical performances for Li–S batteries, including a high capacity of 600 mAh g−1 after 300 cycles at 1 C and a rate capacity of 438 mAh g−1 at 3 C. This work provides a new avenue for the fabrication of graphene‐based hosts with large areal capacity and high‐rate capability for Li metal batteries.

AbstractCation‐intercalated vanadates, which have considerable promise as the cathode for high‐performance potassium metal batteries (PMBs), suffer from structural collapse upon K+ insertion and desertion. Exotic cations in the vanadate cathode may ease the collapse, yet their effect on the intrinsic cation remains speculative. Herein, a stable and dendrite‐free PMB, composed of a Na+ and K+ co‐intercalated vanadate (NKVO) cathode and a liquid NaK alloy anode, is presented. A series of NKVO with tuneable Na/K ratios are facilely prepared using MXene precursors, in which Na+ is testified to be immobilized upon cycling, functioning as a structural pillar. Due to stronger ionic bonding and lower Fermi level of Na+ compared to K+, moderate Na+ intercalation could reduce K+ binding to the solvation sheath and favor K+ diffusion kinetics. As a result, the MXene‐derived Na+‐pillared NKVO exhibits markedly improved specific capacities, rate performance, and cycle stability than the Na+‐free counterpart. Moreover, thermally‐treated carbon paper, which imitates the microscopic structure of Chinese Xuan paper, allows high surface tension liquid NaK alloy to adhere readily, enabling dendrite‐free metal anodes. By clarifying the role of foreign intercalating cations, this study may lead to a more rational design of stable and high‐performance electrode materials.

Published: September 2023

AbstractSelective hydrogenation of nitrostyrenes is a great challenge due to the competitive activation of the nitro groups (─NO2) and carbon–carbon (C═C) double bonds. Photocatalysis has emerged as an alternative to thermocatalysis for the selective hydrogenation reaction, bypassing the precious metal costs and harsh conditions. Herein, two crystalline phases of layered ternary sulfide Cu2WS4, that is, body‐centered tetragonal I‐Cu2WS4 nanosheets and primitive tetragonal P‐Cu2WS4 nanoflowers, are controlled synthesized by adjusting the capping agents. Remarkably, these nanostructures show visible‐light‐driven photocatalytic performance for selective hydrogenation of 3‐nitrostyrene under mild conditions. In detail, the I‐Cu2WS4 nanosheets show excellent conversion of 3‐nitrostyrene (99.9%) and high selectivity for 3‐vinylaniline (98.7%) with the assistance of Na2S as a hole scavenger. They also can achieve good hydrogenation selectivity to 3‐ethylnitrobenzene (88.5%) with conversion as high as 96.3% by using N2H4 as a proton source. Mechanism studies reveal that the photogenerated electrons and in situ generated protons from water participate in the former hydrogenation pathway, while the latter requires the photogenerated holes and in situ generated reactive oxygen species to activate the N2H4 to form cis‐N2H2 for further reduction. The present work expands the rational synthesis of ternary sulfide nanostructures and their potential application for solar‐energy‐driven organic transformations.

Abstract

Objective
To support the declining wild population of Delta Smelt, a conservation hatchery has expanded its mission from maintaining a backup population as insurance against extinction to also producing fish for release into the wild. The substantially higher production demands require a balance between producing large numbers of fish while adhering to conservation genetic principles that maximize retention of effective population size (Ne) and thus overall diversity.

Methods
We performed spawning experiments at the hatchery to evaluate the genetic consequences of two spawning strategies: (1) a pooled strategy where we fertilized premixed eggs from three dams with premixed milt from three sires and (2) a partial-factorial strategy where eggs from three dams were mixed and then apportioned among three containers, each container then receiving milt from one sire. We used genetic parentage analysis of larval offspring to determine the reproductive success of spawners in 10 replicate crosses of each strategy.

Result
The contributions of parents to offspring were more even in partial-factorial crosses and consequently resulted in higher Ne (average Ne = 5.50 ± 0.38; expected Ne = 6.0), suggesting its potential for maintaining genetic diversity over time. In contrast, our pooled spawning experiment produced lower and more variable Ne values (average Ne = 3.86 ± 1.30), demonstrating that this more efficient method of production entails high costs in terms of long-term genetic management. Treating our experiments as hypothetical pools of fish for release, we combined the Ne values for pooled or partial-factorial crosses to calculate the effective size of a release population (NeR). Unequal family sizes reduced NeR for our pooled experiment to half of the expected value, whereas the partial-factorial experiment NeR was 88% of the expected value.

Conclusion
We discuss the benefits and risks of each method and how these can be considered when designing a spawning strategy for Delta Smelt supplementation.

AbstractNovel double DOPO‐grafted phthalonitrile flame retardant (DOPO‐DBAPh) has been successfully synthesized via solution reaction with amino‐substituted phthalonitrile monomer, bisphenol A, paraformaldehyde and 9, 10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO) as initial materials. The molecular structure of DOPO‐DBAPh was investigated by FT‐IR and 1H‐NMR spectrum. Then, the DOPO‐DBAPh was added into epoxy (EP) to construct DOPO‐DBAPh/EP fire‐retarding composites by casting forming method. The effect of different proportions of DOPO‐DBAPh/EP fire‐retarding composites on the microstructure, thermal, mechanical, flame retardancy and combustion behavior was investigated. It was found that the DOPO‐DBAPh/EP fire‐retarding composites have a high glass transition temperature (Tg = 156∼179°C), and also have excellent thermal stability (T5% = 331.4∼365.4°C) and high flexural strength (96.1∼139.8 MPa). When DOPO‐DBAPh content is 5 wt%, the vertical burning grade and limiting oxygen index (LOI) of DOPO‐DBAPh/EP composites reached V‐0 and 29.6%, respectively. Furthermore, the cone calorimeter testing results showed that the addition of DOPO‐BAPh can obviously inhibit the decomposition rate of cured substance at high temperature and accelerated the formation of dense carbon layer. When DOPO‐BAPh content was 20 wt%, the total heat release rate (THR) and peak heat release rate (PHRR) of the DOPO‐DBAPh/EP fire‐retarding composites were decreased by 38.55% and 35.81% compared with that of cured EP. In a word, this work presents a good way for synthesizing economical and highly efficient flame retardant for use in the preparation of EP‐based fire‐retarding composites with excellent comprehensive performance.Highlights
Novel phosphorus‐nitrogen flame retardant (DOPO‐DBAPh) is developed.
5 wt% DOPO‐DBAPh significantly improves the fire safety of EP resin.
The DOPO‐DBAPh/EP composites exhibit good thermal and mechanical properties.

Published: September 2023

AbstractA 2.5‐year‐old, 2.9 kg, neutered, male domestic rabbit presented for sudden onset of sneezing and wheezing of 2‐day duration. Upon physical examination, there was mild dyspnoea characterised by mild to moderate increased inspiratory effort and audible wheeze, without evidence of ocular or nasal discharge. An aggressive expansile lytic mass lesion of the right caudal maxilla extending into the zygomatic arch was identified on skull radiographs. Computed tomography confirmed a large heterogeneously contrast enhancing soft tissue mass associated with the lytic lesion, likely originating from the right alveolar bulla, extending into the zygomatic arch. Histopathological diagnosis was osteosarcoma with areas of osteogenic and fibroblastic patterns. Diseases of the nasal cavity are common in rabbits; while infectious rhinitis remains the most common diagnosis, increasing number of cases of neoplasms involving the maxilla and nasal cavity should remind clinicians to include it in the differential diagnosis list.

AbstractThe sex tech industry is set to experience significant changes as it grows in value and attracts more users. The industry is often divided into five main branches: remote sex, robots, immersive entertainment, virtual sex, and augmentation. Virtual reality (VR) technology has the potential to transform sexual experiences, allowing people to explore different identities and experiment with new sensations. Haptic and multisensory experiences will revolutionize virtual sex, and virtual sexology will enhance people's sexual skills. The COVID-19 pandemic has had an impact on sexual lives, with people turning to sexting and sex toys. The article explores the possibility of humans falling in love, marrying, having sex with robots, and merging with machines. VR contact lenses may even enable dream-based sex. However, the article notes that human touch and contact remain crucial in sexual experiences and technology cannot fully replace them. Despite new technological developments the future of sex will continue to be about the pursuit of pleasure, while genuine human relationships will remain essential.
