A large class of algebras (possibly nonassociative) with group-coalgebraic structures, called quasigroup Hopf group-coalgebras, is introduced and studied. Quasigroup Hopf group-coalgebras provide a unifying framework for the classical Hopf algebras and Hopf group-coalgebras as well as Hopf quasigroups. Then, basic results similar to those in Hopf algebras H are proved, such as anti-(co) multiplicativity of the antipode S: H → H, and S² = id if H is commutative or cocommutative.

Long non-coding RNAs (lncRNAs) have been shown to be aberrantly expressed in oral squamous cell carcinoma (OSCC), but the biological role and function of BRAF-activated long non-coding RNA (BANCR) in OSCC remain poorly understood. In this study, we found that the expression of BANCR was upregulated in OSCC tissues and cell lines compared to the negative control. The decreased expression of BANCR in vitro markedly inhibited OSCC cell proliferation, migration, and invasion while the opposite was observed for the overexpression of BANCR. The results also showed that the expression of MAPK signaling-related proteins (p-erk, p-akt, and p-p-38) was positively correlated with that of BANCR. Thus, BANCR may play an important role in the tumorigenesis of OSCC, as well as cell proliferation, migration, and invasion of OSCC, and it may be a potential therapeutic target and prognostic factor in OSCC patients.

Objective and Background: Sinusoidal obstruction syndrome (SOS) is a life‐threatening complication in hematopoietic stem cell transplantation (HSCT) patients. However, the related risk factors in pediatric and young adult HSCT recipients remain unclear. Thus, we conducted this meta‐analysis to identify potential risk factors for SOS in children and young adults undergoing HSCT. Method: We acquired related articles through searching PubMed, EMBASE, and the Cochrane Library up to May 31, 2024. We calculated odds ratios (ORs) and corresponding 95% confidence intervals (CIs) to identify potential risk factors. Results: A total of 12 studies with 7644 HSCT recipients were included. Bone marrow transplantation (OR = 1.35, 95% CI: 1.03–1.77, I2 = 0%), busulfan (BU) (OR = 3.63, 95% CI: 1.78–7.38, I2 = 70%), and fludarabine (FLU) (OR = 1.55, 95% CI: 1.09–2.21, I2 = 16%) were risk factors for SOS after HSCT in children and young adults. Conclusion: Bone marrow transplantation and the use of BU or FLU might be risk factors for SOS after HSCT in children and young adults. [ABSTRACT FROM AUTHOR]

• IG-DRBEM for solving time-domain infinite domain sound field reconstruction problem. • Non-iterative time-domain acoustic holography method. • POD-RBF prediction of time-domain sound pressure for large-scale structures. In this paper, a novel non-iterative reconstruction method of time-domain sound pressure and rapid prediction scheme of large-scale sound field are proposed respectively based on the isogeometric dual reciprocity boundary element method (IG-DRBEM) and proper orthogonal decomposition - radial basis functions (POD-RBF). By establishing the non-iterative inversion theory in the meaning of least squares, infinite domain acoustic holography is achieved with a small number of measured sound pressure information. Furthermore, the POD-RBF network is adopted to predict large-scale sound pressure. The presented work further expands the scope of application of IG-DRBEM, and gives full play to its advantage of not having to calculate the coefficient matrix repeatedly when analyzing the sound field at different moments. Moreover, in order to satisfy the integral regularization conditions, a suitable convergence condition about variation coefficients is investigated. Numerical results show that the proposed method has high accuracy and good stability even when the sound pressure of complex airship model is predicted with large-scale freedom.

In this work, the Ni nanoparticles (NPs) supported on TiO 2 (Ni-TiO 2) derived from MIL-125 (Ti-MOFs) were synthesized by impregnation method. The results showed that compared with Ni catalysts supported on commercial P25 or Al 2 O 3 , the activity and stability of Ni-TiO 2 catalysts for photo-thermal CO 2 methanation were greatly improved at 325 °C under the full spectrum irradiation (1200 mW/cm2). The conversion of CO 2 was 56 %, which was about 1.8 times of that without light irradiation. The methane yield was 95.7 mmol/(g cat ∙h), which was 2.7 times higher than that without light irradiation. The excellent performance of Ni-TiO 2 can be attributed to the fact that the catalyst prepared by derived from MOFs possessed large specific surface areas, abundant moderate strength alkaline sites, which can promote the dispersion of Ni NPs and provide more active sites for the adsorption and activation of CO 2. Moreover, Ni-TiO 2 showed good photo-thermal and photo-electric conversion ability, which make the catalysts possess more photo-generated charge carriers and reduce its recombination. [Display omitted] • The dispersed Ni NPs supported on defective TiO 2 derived from MOFs was successfully synthesized. • The Ni dispersion, surface area of catalysts and the ability of photo-electricity and photo-thermal properties were characterized by various technology. • The activity and stability of photo-thermal CO 2 methanation were realized by using TiO 2 supported Ni which was derived from MOFs. • The excellent photo-thermal catalytic performance of Ni-TiO 2 can be attributed to the good photo-electric and photo-thermal conversion ability. Catalytic reduction of CO 2 to high value-added chemicals such as methane is crucial in the development of renewable energy and waste disposal. Photo-thermal CO 2 methanation has been received great attention, because the synergistic effect of photo and thermal lead to efficient CO 2 reduction at low temperature. Herein, we reported the synthesis of Ni nanoparticles (NPs) supported on TiO 2 (Ni-TiO 2) derived from MIL-125 (Ti-MOFs) for photo-thermal CO 2 methanation. The nanoparticle sizes and electron densities of metallic Ni, defects and chemical properties, photo-thermal and photo-electric characteristics of the catalysts have been systematically characterized by XRD, TEM, CO 2 /H 2 -TPD, XPS, photoluminescence and photocurrent. For the Ni-TiO 2 , the conversion of CO 2 was 56 % under the full spectrum irradiation (1200 mW/cm2) at 325 °C, which was about 1.8 times of that without light irradiation. The selectivity of methane nearly 99 % with a production rate was 95.7 mmol/(g cat ∙h), which was about 2.7 times of that without light irradiation. Meanwhile, the catalysts showed excellent stability without any activity decay during the four cycles testing (32 h). The main reasons for the high catalytic performance for photo-thermal CO 2 methanation were attributed to the uniform distribution of Ni NPs with synergistic effect of large specific surface area of TiO 2 with abundant moderate strength alkaline sites. In addition, good photo-thermal and photo-electric conversion ability make the catalysts possess more photo-generated charge carriers and reduce its recombination. [ABSTRACT FROM AUTHOR]

Byline: Jianhai Zhang, Huaixiang Zhang, Guojun Dai, Senlin Zhang, Meiqin Liu This paper addresses the stabilisation problem of discrete-time recurrent neural networks (RNNs) containing norm-bounded uncertainties. A novel neural network model, named standard neural network model (SNNM), is used to provide a general framework for robust stabilising controller synthesis of RNNs. Most of the existing RNNs can be transformed into SNNM to be synthesised in a unified way. Applying the Lyapunov stability theory and the S-procedure technique, state feedback controllers are designed to guarantee the global asymptotical stability of closed-loop dynamic discrete-time systems. The controller gains are obtained by solving a set of linear matrix inequalities. Examples are given to illustrate the transformation procedure and the effectiveness of the proposed design technique.
