Published: July 2023

Abstract
Delivering the highest power among the visible diodes, semiconductor lasers at 450 nm have been extensively applied in biomedical and micro-processing fields. However, the edge-emitting inherence that gives birth to the divergent and ununiform profile largely prohibits the practice due to the fiber coupling and pumping difficulty. To address these challenges, we propose and demonstrate a scheme that is both robust and cost-effective. A laser spot with 3×3 mm2 profile, 0.86 mrad divergence and 87.28% uniformity is experimentally achieved. Further simulation reveals that the coupling efficiency into a S460-HP single-mode fiber by a 20-mm focus-lens can reach 58.35%.

Abstract
With the development of communication technologies, the technology of power support, particularly the technology of lithium-ion batteries plays an important role in the communication area. The evaluation for the remaining useful life of lithium-ion batteries is a hot issue, to provide the maintenance plans and ensure the reliability and safety of system. In this paper, a method using particle filter algorithm for the remaining useful life prediction of lithium-ion batteries in communication power supply is carried out, and the comparisons of prediction effect with the least square method are investigated. From the results, it is clearly seen that the proposed particle filter algorithm presents a better prediction accuracy and stability than the least square method. In addition , the proposed particle filter algorithm presents a weak data dependence than the least square method. For a better prediction result, the number of data to be predicted by the proposed particle filter algorithm accounts about 55% of the total number of the cycle time, which is smaller than that accounts 70% by the least square method. This paper provides a technology support for the remaining useful life prediction of lithium-ion batteries.

Abstract
Background:
This study aimed to evaluate the efficiency of stromal derived from adipose tissue in the treatment of osteochondral defects in rabbits. A total of 36 white New Zealand rabbits were used: 24 to perform an osteochondral defect in the trochlear groove of the joints and 12 to collect adipose tissue in the region of the adipose panicle, divided in three digestion times (30, 45 and 50 minutes). The groups were divided into negative control (C-), stromal fraction of adipose tissue (SFAT) and positive control (C+) with autogenous osteochondral graft.
Results:
Clinical, radiographic, macroscopic and histopathological evaluations showed that the therapeutic effects of the stromal fraction of adipose tissue minimized the degenerative signs of articular cartilage in the treatment of osteochondral defects in rabbits.
Conclusion:
The digestion time of 30 minutes was the best option for obtaining the stromal fraction from adipose tissue of rabbits and its use at the lesion site was satisfactory, without any immunological complications, indicating potential as an alternative for the treatment of osteochondral defects.

Abstract
Objective: To determine whether preterm birth of 32-36 6/7 weeks gestation affected school performance from kindergarten through fifth grade.
Study Design: We assessed 14350 full-term infants and 1195 moderately and late preterm infants followed in the Early Childhood Longitudinal Study Kindergarten 2011 cohort for classroom performance in kindergarten-fifth grade. Multivariable regression was performed for comparisons, and data were weighted to be representative of the U.S. population.
Results: Children born late preterm had no significant difference in their academic scores or performance, while moderately preterm children had lower academic scores and teacher performance scores when compared to full-term children. Both moderately and late preterm children had higher odds of individualized education plan needs and had learning disability diagnoses.
Conclusions: Moderately preterm children have poor school performance compared to full-term children. Both moderately and late preterm children are at risk for learning disabilities and likely benefit from continued support and services to improve achievement throughout school.

Published: July 2023

Abstract
In recent years, the digitalization of ancient villages and towns has been iterated and updated with the development of technology, and a series of new experiences, new consumption and new scenes have become the new engine for the development of ancient towns. Ancient towns are an important branch of human cultural heritage. However, the digitalization of ancient towns has the problem of "emphasizing technology and neglecting culture" to some extent. Based on the theory of landscape gene, this paper puts forward the principles of cultural landscape digital gene and landscape digital gene. In the process of digital transformation of ancient towns, digital genes of cultural landscape should be identified from a new perspective of genetic attributes. In the process of digital transformation of ancient town, the digital gene of cultural landscape plays the role of decoder, realizing the process of "cultural decoding - cultural coding". Under this framework, the paper conducted an empirical study of Nanxun Ancient Town, Huzhou, China, a world Heritages listed ancient town, proposed a digital path for Nanxun Ancient Town according to the steps of landscape gene extraction, landscape digital gene generation and landscape digital transformation, and constructed the digital transformation path of Nanxun Ancient Town. The research aims to provide new ideas for the digitalization of scenic spots, especially the digitalization of cultural heritage, and put forward thoughts on the risk prevention of "digital destruction" of heritage scenic spots.
Properties of relativistic hot accretion flow around rotating black hole with radially varying viscosity
Authors: Singh Monu , Das Santabrata 
Published: July 2023

Abstract
We examine the effect of variable viscosity parameter ($\alpha$) in relativistic, low angular momentum advective accretion flow around rotating black holes. Following the recent simulation studies of magnetohydrodynamic disk that reveal the radial variation of $\alpha(r)$, we theoretically investigate the properties of the global transonic accretion flow considering a one-dimensional power law prescription of viscosity parameter as $\alpha(r) \propto r^{\theta}$, where the viscosity exponent $\theta$ is a constant. In doing so, we adopt the relativistic equation of state and solve the fluid equations that govern the flow motion inside the disk. We find that depending on the flow parameters, accretion flow experiences centrifugally supported shock transition and such shocked accretion solutions continue to exist for wide ranges of the flow energy, angular momentum, accretion rate and viscosity exponent, respectively. Due to shock compression, the hot and dense post-shock flow (hereafter PSC) can produce the high energy radiations after reprocessing the soft photons from the pre-shock flow via inverse Comptonization. Since PSC is usually described using shock radius ($r_s$), compression ratio ($R$) and shock strength ($S$), we study the role of $\theta$ in deciding $r_s$, $R$ and $S$, respectively. Moreover, we obtain the parameter space for shock and find that possibility of shock formation diminishes as $\theta$ is increased. Finally, we compute the limiting value of $\theta$ ($i.e., \theta^{\rm max}$) that admits shock and find that flow can sustain more viscosity when it accretes onto rapidly rotating ($a_{\rm k} \rightarrow 1$) black hole in comparison to weakly rotating ($a_{\rm k} \rightarrow 0$) black hole.

Abstract
In this work, polylactic acid/poly (butylene adipate-co-terephthalate) (PLA/PBAT) melt-blown nonwovens with well oil-water separation properties were made with melt-blown technology. The thermal, crystalline, morphology, mechanical properties, wettability, and oil-water separation performance of the PLA/PBAT melt-blown nonwovens were thoroughly investigated. The result of DSC and WAXD show that PBAT promotes the movement of the PLA molecular chain and promotes crystallinity. With increasing the blending ratio of PBAT, the ΔHm and degree of crystallinity (Xc) of PLA were also enhanced from 38.1 to 55.1 J/g and from 1.5–15.5%, respectively, which were higher than neat PLA. Furthermore, PBAT increases the toughness and hydrophobic of the PLA melt-blown nonwovens. The elongation at break of PLA/PBAT 90/10 (53.3 ± 3.7%) was 12.3% higher than the neat PLA melt-blown nonwovens (41.0 ± 2.9%). The result of the research on the influence of the oil-water separation parameters and oil absorption experiments shows that the 90/10 PLA/PBAT melt-blown nonwoven exhibits the highest hydrophobic (water contact angle is 133.2o). Meanwhile, the maximum adsorption efficiency of cyclohexane of nonwovens reaches 5.18 g/g. The PLA/PBAT melt-blown nonwovens have excellent oil-water separation capability.

Published: July 2023

Abstract

The production of spherical powders has recently registered a boost due to the need of fabricating new printing materials for Additive Manufacturing applications, from polymers and resins to metals and ceramics. Among these materials, stainless steels powders play a leading role, since they are widely used in industry and everyday life; indeed, micron-sized spherical stainless-steel powders have specific characteristics and are considered as one of the best candidates for Additive Manufacturing systems and for the application in a wide range of sectors. In this paper, stainless steel 316L powders were used to explore and identify the best process parameters of a thermal plasma process able to produce spherical powders for Additive Manufacturing applications. X Ray Diffraction, Scanning Electron Microscopy and Flowability analysis were performed to characterize reagents and products. Powders with high circularity (> 0.8) and improved flowability (< 30 sec / 50g) were successfully obtained. The collected results were compared with data available in the literature to identify the potential use of the spherical produced powders.

Abstract
Purpose The purpose of this study was to prospectively investigate the incidence of influenza-associated pulmonary aspergillosis (IAPA) in influenza patients admitted to intensive care units in Sweden.Methods The study included consecutive adult patients with PCR-verified influenza A or B in 12 Swedish intensive care units (ICUs) over four influenza seasons. Patients were screened using serum galactomannan and β-d-glucan tests and fungal culture of a respiratory sample at inclusion and weekly during the ICU stay. Bronchoalveolar lavage was performed if clinically feasible. IAPA was classified according to recently proposed case definitions.Results The cohort included 55 patients; 42% were female, and the median age was 59 (IQR 48–71) years. All patients had at least one galactomannan test, β-d-glucan test and respiratory culture performed. Bronchoalveolar lavage was performed in 24 (44%) of the patients. Five (9%, 95% CI 3.8% − 20.4%) patients were classified as probable IAPA, of which four lacked classical risk factors. The overall ICU mortality was significantly higher among IAPA patients than non-IAPA patients (60% vs 8%, p = 0.01).Conclusion The study represents the first prospective investigation of IAPA incidence. The 9% incidence of IAPA confirms the increased risk of invasive pulmonary aspergillosis among influenza patients admitted to the ICU. Therefore, it appears reasonable to implement a screening protocol for the early diagnosis and treatment of IAPA in influenza patients receiving intensive care.Trial registration ClinicalTrials.gov NCT04172610, registered November 21, 2019

Published: July 2023

Abstract
To enhance the quality of life for dialysis patients while maintaining economic efficiency, the concept of a wearable artificial kidney was proposed and designed approximately two decades ago. However, the primary challenge in the development of a wearable artificial kidney is the adequate removal of urea from dialysate due to its chemical inertness under physiological conditions. Herein, a hollow polystyrene nanoparticle with sulfuric acid groups, named H-CPS-SO3H, was synthesized, which could efficiently adsorb urea. H-CPS-SO3H was produced in three steps. First, a core-shell polystyrene nanoparticle with a linear core and cross-linked shell was prepared using modified emulsion polymerization. Second, the core-shell nanoparticle was treated with DMF to create a hollow nanoparticle. Finally, the hollow nanoparticle was subjected to sulfuric acid treatment to produce H-CPS-SO3H, which was confirmed by both TEM and FTIR analysis. The urea adsorption capacity and kinetics of the as-synthesized H-CPS-SO3H were evaluated under a 30 mM urea concentration. Results indicated that H-CPS-SO3H had a urea absorption capacity of up to 1 mmol/g, which was achieved after only two hours of adsorption at 37 ℃. These findings demonstrated the high adsorption capacity and favorable adsorption kinetics of H-CPS-SO3H. Additionally, it was observed that the adsorption capacity first increased and then slightly decreased with the decrease of pH or the increase of solution volume, while the adsorption capacity sharply decreased with the increase of ionic strength. The results suggest that the prepared H-CPS-SO3H has promising application prospects in the field of wearable artificial kidney devices.

Abstract
Background
Palatine tonsils are mucosa-associated lymphoid organs that constantly engage in crosstalk with commensal microorganisms and the immune system. Focal infections at tonsils have been implicated in the pathogenesis of autoimmune diseases including rheumatoid arthritis (RA), but the underlying mechanisms through which tonsils contribute to host autoimmunity remain poorly defined.
Results
We identified a significant dysbiosis of tonsillar microbiota in RA patients, which was largely associated with disease activity. RA tonsillar microbiota was featured by an expansion of opportunistic pathogenic Streptococcus species including S. pyogenes, S. dysgalactiae and S. agalactiae, along with a contraction of numerous commensal Streptococcus members like S. salivarius. By defining a Streptococcus dysbiosis index, we found that RA patients, especially those without medication, were overrepresented in the Streptococcus dysbiotic set. Moreover, the intra-genus dysbiosis of Streptococcus in tonsillar microbiota was closely correlated with abnormal expression of circulating anti-streptolysin O, LPS-binding protein, soluble CD14, T helper 17 and natural killer cells. Finally, we demonstrated that the RA-deficient S. salivarius inhibited arthritis development and autoimmune responses.
Conclusions
Collectively, our study uncovers the functional link between host immune responses and tonsillar microbiota, and demonstrates that intra-genus dysbiosis of Streptococcus species contribute significantly to host autoimmunity.

Abstract
Background
Recent studies identified coronavirus disease 2019 (COVID-19) as a risk factor for invasive pulmonary aspergillosis (IPA) but produced conflicting data on IPA incidence and impact on patient outcomes. We aimed to determine the incidence and outcomes of COVID-19-associated pulmonary aspergillosis (CAPA) in mechanically ventilated patients.
Methods
We performed an observational cohort study in consecutive adults admitted to 15 French intensive care units (ICUs) in 2020 for COVID-19 requiring mechanical ventilation. CAPA was diagnosed and graded according to 2020 ECMM/ISHAM consensus criteria. The primary objective was to determine the incidence of proven/probable CAPA, and the secondary objectives were to identify risk factors for proven/probable CAPA and to assess the impact of proven/probable CAPA on patient outcomes.
Results
The 708 included patients (522 [73.7%] men) had a mean age of 65.2 ± 10.8 years, a mean mechanical ventilation duration of 21.0 ± 20.5 days, and a day-90 mortality rate of 28.5%. Underlying immunosuppression was present in 113 (16.0%) patients. Corticosteroids were used in 348 (63.1%) patients. Criteria for probable CAPA were met by 18 (2.5%) patients; no patient had histologically proven CAPA. Age was the only factor significantly associated with probable CAPA (hazard ratio [HR], 1.04; 95%CI, 1.00–1.09; P = 0.04). Probable CAPA was associated with a significantly higher day-90 mortality (HR, 2.07; 95%CI, 1.32–3.25; P = 0.001) but not with longer mechanical ventilation or ICU length of stay.
Conclusion
Probable CAPA is a rare but serious complication of severe COVID-19 requiring mechanical ventilation and is associated with higher day-90 mortality.
