Authors: Karkri Rafik , Kabbaj Samir , Lafdal Hamad Sidi 
Published: July 2023

Abstract
In this paper, we prove the following results. There exists a Banach space without basis which has a Schauder frame. There exists an universal Banach space B (resp. $\tilde{B}$) with a basis (resp. an unconditional basis) such that, a Banach X has a Schauder frame (resp. an unconditional Schauder frame ) if and only if X is isomorphic to a complemented subspace of B (resp. $\tilde{B}$). For a weakly sequentially complete Banach space, a Schauder frame is unconditional if and only if it is besselian. A separable Banach space X has a Schauder frame if and only if it has the bounded approximation property. Consequenty, The Banach space L(H, H) of all bounded linear operators on a Hilbert space H has no Schauder frame. Also, if X and Y are Banach spaces with Schauder frames then, the Banach space $ X\widehat{\otimes}_{\pi}Y$ (the projective tensor product of X and Y) has a Schauder frame. From the Faber-Schauder system we construct a Schauder frame for the Banach space C [0,1] (the Banach space of continuous functions on the closed interval [0,1]) which is not a Schauder basis of C [0,1]. Finally, we give a positive answer to some open problems related to the Schauder bases (In the Schauder frames setting).

Abstract
Backgrounds:
To evaluate the causal correlation between complement components and non-viral liver diseases and their potential use as druggable targets.
Methods
Two-sample Mendelian randomization (MR) was performed to assess the causal effect of circulating complement components on the risk of several non-viral liver diseases. Then complement-based protein-protein interaction network was constructed to explore its involvement in the biological processes and network-based analysis of drug repositioning was conducted.
Results
In the MR analysis, genetically predicted levels of complement factor H-related protein 1 (CFHR1; OR: 0.621, p = 2.7*10− 5) and H-related protein 2 (CFHR2; OR: 0.621, p = 2.7*10− 5) were inversely associated with the risk of alcohol-related cirrhosis (ALC). Associations were significant between C8 gamma chain (C8G) and the risk of nonalcoholic fatty liver disease (NAFLD) (OR: 1.167, p = 0.011) and primary sclerosing cholangitis (PSC) (OR: 0.832, p = 0.027), C1QC chain (C1QC) and autoimmune hepatitis (AIH) (OR: 1.125, p = 0.021), and H-related protein 5 (CFHR5) and primary sclerosing cholangitis (PSC) (OR: 1.193, p = 0.007). Additionally, C1s (OR: 0.111, p = 0.017), C7 (OR: 1.631, p = 0.002), and CFHR2 (OR: 1.279, p = 0.011) were significantly associated with the risk of hepatocellular carcinoma. Protein-protein interaction network analysis showed that complement and complement-related proteins were widely enriched in liver disease-related biological functions. Potential drugs, including imatinib, thalidomide, verteporfin, atorvastatin, bortezomib, and calcitriol were highlighted for treating non-viral liver diseases.
Conclusions
Our study suggests complement components, such as CFHR1, CFHR2, C8G, C1QC, CFHR5, and C1S may be causally linked to non-viral liver diseases and could potentially serve as drug targets.

Published: July 2023

Abstract
This paper introduces a neural network adjustment method for a single gain of an IP speed regulator, to improve the speed control of an induction motor. Thanks to its simplicity and strength the (IP) controller is widely used in the industry for speed control. Yet, in some cases, when the load or mechanical parameters change according to its working conditions, the IP efficiency decreases and the setup quality degrades. In this case, a neural IP-self- tuning seems to overcome these difficulties and ensure a good control performance. The results obtained through the implementation of the proposed control on a dSPACE system and an induction motor clearly demonstrate the effectiveness of this method.

Published: July 2023

Abstract
Al2O3 aerogels are attractive for thermal insulation due to their low thermal conductivity at room temperature and high heat resistance performance. However, poor mechanical properties and high thermal conductivity at high-temperatures limit their practical applications. Herein, HNTs/Al2O3 interpenetrating dual network aerogels was successfully prepared by vacuum impregnation, sol-gel process and CO2 supercritical drying technology. The unique interpenetrating dual network structure of the HNTs/Al2O3 aerogels endows it with integrated performances of the excellent mechanical strength (1.85-2.06 MPa), good thermal stability (~1000 ℃) and ultralow thermal conductivity at high temperature (~0.055 W m-1 K-1, 1000 ℃). These favorable multi-features of aerogels are expected to be widely applied in aerospace and other high temperature environments.

Published: July 2023

Abstract
Rockburst is a serious disaster caused by the sudden release of rock energy during underground construction in high-stress environments, resulting in severe damage to underground structures. Accurately predicting rockburst intensity is challenging, and establishing a reliable and precise prediction model is of great importance. In this study, we proposed a novel hybrid model for predicting rockburst intensity by integrating rough set theory and multidimensional cloud model uncertainty reasoning. The key steps of the proposed method are as follows: (1) Rockburst cases are collected, and the maximum shear stress \({\sigma }_{\theta }\), uniaxial compressive strength \({\sigma }_{c}\), uniaxial tensile strength \({\sigma }_{t}\), and elastic energy index \({W}_{et}\) are used as predictors for rockburst strength. (2) The Shannon entropy method is used to determine the weights of the four indicators, and a rockburst potential expression is constructed. (3) Rough set theory is used to reduce the number of indicators to construct a rockburst strength prediction rule library. (4) Qualitative data are transformed into quantitative data by using the rules library and multidimensional cloud model to establish an uncertainty inference framework for predicting rockburst strength. Finally, we compared the performance of the hybrid model with existing models, and the results demonstrate that the proposed approach achieves similar or even higher prediction accuracy. The use of cloud droplets in the model offers a significant advantage in the prediction of mixed rockburst intensities, enabling intuitive, rapid, and effective determination of the occurrence intensity of rockbursts.

Published: July 2023

Abstract
This paper analyzes the importance of digital game-based learning within the higher military education system. The advantages of implementing digital wargaming in the learning system are presented, including its risk-free and cost-effective nature, its ability to allow “what-if” scenarios, facilitate knowledge transfer, skill acquisition, attitudinal/behavioral change, time-saving benefits, and the ability to understand the operational environment or test new technologies. The combination of these specific advantages, along with the motivation derived from the enjoyment of the game, should be the focus of military education academics and practitioners. Additionally, the paper highlights the requirements that the chosen game must meet, such as complexity, realism, balance, and providing opportunities for learning and developing skills that are tracked through data collection and subsequent feedback. By integrating digital games and using the principle of “play, have fun and learn”, the learning process in higher military education can effectively improve the development of essential tactical skills that are difficult to achieve through other traditional teaching methods.

Вдосконалення відомих алгоритмів сортування та розроблення нових підходів до сортування пов’язано, в першу чергу, з їх широким застосуванням у найпоширеніших у теперішній час прикладних областях. Це стосується, наприклад, пошукових систем, систем управління БД, нейромережних та експертних технологій, попереднього оброблення сигналів і зображень. Поряд з розвинутими програмними засобами сортування масивів даних певний інтерес представляють апаратні реалізаційні моделі сортування, як однієї з найбільш розповсюджених асоціативно-логічних операцій. Особливо це стосується паралельних методів сортування, до яких належать варіанти їх мережного подання. У статті розглянуто особливості мережного алгоритму сортування лінійного числового масиву на базі відомого методу попарного обміну. Особливістю запропонованого підходу є використання сформованих рангів відповідних елементів масиву в процесі їх сортування. В результаті поступове перетворення (підлаштування) рангів елементів масиву дозволяє відмовитись від необхідності виконання складної процедури перекомутації самих елементів у сформованих парах. Ця трудомістка операція замінюється швидкісними операціями інкремента/декремента над відповідними рангами. Для порівняння у вигляді таблиці показано приклад по циклах двох процесів сортування: за класичним мережним методом попарного обміну і запропонованим підходом з формуванням відповідних рангів. Наведено класичний варіант покрокового опису алгоритму мережного сортування з ранжуванням. Для порівняння представлено опис цього алгоритму у термінах системи алгоритмічних алгебр (САА) Глушкова. Такий підхід свідчить про компактність подання запропонованого алгоритму, а також дозволяє показати значний рівень паралелізму оброблення, притаманний мережним алгоритмам сортування.
Adebrelimab plus chemotherapy vs. chemotherapy for treatment of extensive-stage small-cell lung cancer from the US and Chinese healthcare sector perspectives: a cost-effectiveness analysis to inform drug pricing
Authors: Gan Yena , Shi Fenghao , Zhu He , Han Sheng , Li Duoduo 
Published: July 2023

Purpose: The aim of this study was to evaluate the cost-effectiveness of a recently approved first-line therapy (adebrelimab plus chemotherapy vs. chemotherapy alone) for patients with extensive-stage small-cell lung cancer (ES-SCLC) in the US and China, and to estimate the reasonable range of adebrelimab price from the decision-makers.Methods: Several partitioned survival models were built to compare the cost and effectiveness of adebrelimab plus chemotherapy vs. chemotherapy alone over a 10-year time horizon. Clinical efficacy and safety data were extracted from the CAPSTONE-1 trial. Costs and utilities were obtained from previously published studies. Sensitivity, scenario and subgroup analyses were performed to explore the uncertainty of the model outcomes. Price simulation was conducted at three thresholds of willingness-to-pay (WTP), including WTP of $100,000 in the US and of $37,422 in China, 0.5WTP of $50,000 in the US and of $18,711 in China, and 1.5WTP of 150,000 in the US and of $56,133 in China.Findings: Base-case analysis at $1382.82/600 mg of adebrelimab price indicated that adebrelimab plus chemotherapy would be cost-effective in the US at the WTP threshold of $100,000, but not in China at the WTP threshold of $37,422. If PAP was taken into account, the regimen would be cost-effective in China at the given WTP. The results of price simulation indicated that adebrelimab plus chemotherapy was completely favored in the US if adebrelimab price was less than $8894.98/600 mg (total quality-adjusted life years [QALYs] were calculated with progression-based utility [PB-utility]) or $8912.51/600 mg (total QALYs were calculated with time-to-death utility [TTD-utility]) at the WTP threshold of $100,000; if adebrelimab price was reduced by at least $202.03/600 mg (total QALYs were calculated with PB-utility) or $103.06/600 mg (total QALYs were calculated with TTD-utility), the regimen was also cost-effective in China without PAP at the WTP threshold of $37,422. The above results were stable in the sensitivity analyses. Subgroup analysis found that the subgroup with better survival benefits tended to have a higher probability of cost-effectiveness, which was also associated with adebrelimab price.Implications: First-line adebrelimab plus chemotherapy represented a dominant treatment strategy comparing with chemotherapy alone in the US and also did in China with PAP at $1382.82/600 mg of adebrelimab price. Decision-makers could benefit from pricing strategy provided by this study in making optimal decisions. More evidences were needed to verify and improve the results.

Published: July 2023

BackgroundPsychosis is known to have an adverse impact on an individual’s quality of life, social and occupational functioning. A lack of treatment options for psychotic disorders such as schizophrenia contributes to adverse outcomes for individuals. A significant proportion of people with psychosis consult both formal and traditional routes of care. This warrants a need to explore perceptions around treatment options provided by diverse care providers, as the identification of avenues for support can improve psychiatric, alternative treatment and social outcomes.MethodsFocus groups discussions (FGDs) and in-depth interviews (IDIs) were used. Interactive Research and Development (IRD) research staff conducted 20 IDIs and 2 FGDs to obtain information about the perspectives, treatment pathways and experiences of individuals with psychosis, their caregivers, and service providers. Questions for clinician care providers and faith healers revolved around perceptions of psychosis, service users’ background, subject knowledge and treatment, feedback and referral mechanisms, and promotion of services. A thematic analysis was used to analyze the interviews and coding was conducted on NVivo.ResultsThe results were categorized into five themes: perception of psychosis, experience of seeking/receiving care, assessment and diagnosis methods, promotion of services, and living with psychosis. Across service providers and patients, there was a wide variety of causes attributed to psychosis, and an overall lack of awareness regarding severe mental health conditions from both formal and informal care-providers. Biomedical treatment received mixed reviews, while some reported it as beneficial, the limited number of institutes and clinicians to cater for patients, stigma within society and care providers, the burden of caregiving, and misinformation from faith healers were all significant barriers to treatment.ConclusionThe results highlight the use of traditional healing practices for psychosis in Pakistan, which, coupled with inadequate referral mechanisms, present an opportunity to bridge the treatment gap between clinical and traditional healing practices through integration of treatment within community structures and systems. Better awareness of psychosis and its treatment methods, alongside interventions that reduce stigma could help facilitate help-seeking behavior and reduce the burden of caregiving.

Published: July 2023

ObjectiveThere is considerable debate as to whether the continuum of major psychiatric disorders exists and to what extent the boundaries extend. Converging evidence suggests that alterations in hippocampal volume are a common sign in psychiatric disorders; however, there is still no consensus on the nature and extent of hippocampal atrophy in schizophrenia (SZ), major depressive disorder (MDD) and bipolar disorder (BD). The aim of this study was to verify the continuum of SZ – BD – MDD at the level of hippocampal subfield volume and to compare the volume differences in hippocampal subfields in the continuum.MethodsA total of 412 participants (204 SZ, 98 MDD, and 110 BD) underwent 3 T MRI scans, structured clinical interviews, and clinical scales. We segmented the hippocampal subfields with FreeSurfer 7.1.1 and compared subfields volumes across the three diagnostic groups by controlling for age, gender, education, and intracranial volumes.ResultsThe results showed a gradual increase in hippocampal subfield volumes from SZ to MDD to BD. Significant volume differences in the total hippocampus and 13 of 26 hippocampal subfields, including CA1, CA3, CA4, GC-ML-DG, molecular layer and the whole hippocampus, bilaterally, and parasubiculum in the right hemisphere, were observed among diagnostic groups. Medication treatment had the most effect on subfields of MDD compared to SZ and BD. Subfield volumes were negatively correlated with illness duration of MDD. Positive correlations were found between subfield volumes and drug dose in SZ and MDD. There was no significant difference in laterality between diagnostic groups.ConclusionThe pattern of hippocampal volume reduction in SZ, MDD and BD suggests that there may be a continuum of the three disorders at the hippocampal level. The hippocampus represents a phenotype that is distinct from traditional diagnostic strategies. Combined with illness duration and drug intervention, it may better reflect shared pathophysiology and mechanisms across psychiatric disorders.
