Abstract
Hierarchical ZSM-5 with a caterpillar-shaped morphology is hydrothermally synthesized, and characterized by XRD, SEM, TEM, N2 adsorption-desorption, and NH3-TPD. The synthetic parameters influence on the formation of the caterpillar-shaped hierarchical ZSM-5 are investigated and discussed in details. The results suggest that nano-sized ZSM-5 zeolite crystals is yielded from an appropriate precursor and then forms the caterpillar-shaped hierarchical ZSM-5 by in-situ self-assembly of the primary nanocrystals. SEM and TEM images display that the primary crystals in the caterpillar-shaped zeolite samples formed by self-assembly along b-axis of MFI zeolite have a size of about 100 nm. Catalytic cracking of triisopropylbenzene (TIPB) is selected as a probe reaction so as to investigate the catalytic performances of the as-synthesized caterpillar-shaped hierarchical ZSM-5 zeolite. The results show that the as-synthesized hierarchical ZSM-5 zeolite with the increased external surfaces exhibits an elevated catalytic activity during the catalytic cracking of TIPB, and the corresponding traditional ZSM-5 zeolite displays very little activity because of the small external surfaces. The results also shows that for the hierarchical ZSM-5-40-5.32-2.1, due to the high external surfaces and the interpenetrated hierarchical pore system, a multi-stage cracking process for the reaction TIPB molecule is detected. That may offer a potential highly effective catalyst for the catalytic cracking of bulky reactant molecule.

Abstract
The performance of BeiDou Navigation Satellite System (BDS) B2a signal acquisition and tracking is affected when co-existing with the Distance Measuring Equipment (DME) pulse signals in the same frequency band. To mitigate the detrimental impacts of DME interference on the B2a receiver, an adaptive hybrid blanking algorithm is proposed which contains time-domain interference detection and frequency-domain interference suppression modules. With flexible configurations, the proposed algorithm is capable of optimizing the interference mitigation according to the strength of the detected DME signals indicated by Jammer-to-noise ratio (J/N). A laboratory testbed is first built to collect simulated B2a data contaminated by DME interference. An empirical model is established to relate J/N with 𝑘𝛼, which is the key parameter of the notch filter that affects the performance of the proposed algorithm. To verify the performance of the proposed algorithm, outdoor experiments are conducted near 2 DME stations close to the Beijing Capital International Airport. The carrier-to-noise density ratio (C/N0) and code tracking errors are analyzed with different mitigation methods applied, including pulse blanking, notch filter and hybrid blanking. Results show that the proposed adaptive hybrid blanking algorithm can achieve the maximum C/N0 and minimum code tracking error. In particular, when applying the proposed algorithm, the mean C/N0 is improved by up to 3.32 dB compared with that when no mitigation method is applied. This study contributes to the development of novel DME interference mitigation approaches to improve the robustness of airborne GNSS receivers.

Abstract
We report a case of primary thyroid rhabdomyosarcoma in a 61-year-old woman. Histologically, the neoplasm was composed of sheets of pleomorphic or spindle-shaped cells with eosinophilic cytoplasm and few large and very pleomorphic cells admixed with the spindle cell proliferation, without any thyroid epithelial component. Immunohistochemically, the tumour cells were positive for muscular markers and negative for epithelial and thyroid differentiation markers (AE1-AE3, EMA, CK5/6, TTF1, PAX8, thyroglobulin). Molecular tests revealed the presence of NF1, PTEN and TERT pathogenic mutations. Major morphological differential diagnoses include anaplastic thyroid carcinoma with rhabdoid phenotype, leiomyosarcoma, as well as other rare sarcomas. In this study, we describe the fifth case in the literature of primary thyroid rhabdomyosarcoma and the third in adults with, for the first time, an extensive molecular analysis.

Abstract
In this paper, we investigate the electromagnetic response of metasurfaces due to excitation of the toroidal moment. An all-dielectric curved metasurface analyzad using a novel theoretical solution based on the Fourier analysis to evaluate the localized fields. Analyzing localized near-field interactions are crucial in investigating the excited trapped modes and enables us to optimize the reflection properties of the proposed metasurface. Optimization is accomplished using graphene layer and resulted a hybrid dielectric-graphene structure with near-zero reflection properties.

Published: January 2023

Abstract
Purpose: To compare the pregnancy outcomes of frozen-thawed embryo transfer (FET) with different endometrium preparation protocols among patients with thin endometrium, including moderate ovarian stimulation (MOS) and hormone replacement therapy (HRT).
Methods:A retrospective cohort study was conducted among patients with endometrium ≦ 7mm. A total of 104 FET cycles were included and analyzed in two groups according to the endometrial preparation protocols, including 52 cycles in the MOS group and 52 cycles in the HRT group, respectively. The primary outcomes consisted of the clinical pregnancy rate and live birth rate.
Results:After adjusting for confounders with multivariable logistic regression, clinical pregnancy rate in the MOS group appeared to be significantly higher than that in the HRT group (40.38% vs. 19.23%; aOR 3.02, 95% CI 1.11-8.17, P=0.030). The significant improvement of live birth rate in the MOS group was shown only before adjustment (30.76% vs. 13.46%; OR 2.73, 95% CI 1.01-7.37, P=0.047; aOR 2.51, 95% CI 0.84-7.51, P=0.100). In addition, biochemical pregnancy rate (48.08% vs. 28.85%, P=0.044) and ongoing pregnancy rate (30.76% vs. 13.46%, P=0.033) of the MOS group were higher than those in the HRT group, while no significant difference was found in ectopic pregnancy rate (P=1.000), miscarriage rate (P=1.000), gestational age at delivery (P=0.626), birth weight (P=0.278) and birth length (P=0.662).
Conclusion:Compared with HRT, MOS protocol could be an alternative strategy to improve the clinical pregnancy rate of patients with thin endometrium for the FET cycle.
In silico analysis of transcription binding site motifs in endogenous and exogenous retroviruses emphasizes their conservation
Authors: Gomez-Lucia Esperanza , Ocaña Julia , Benitez Laura , Domenech Ana 
Published: January 2023

Abstract
LTRs flanking the proviral genome in retroviruses are functionally divided into three regions: U3, R and U5. Transcription starts in the first nucleotide of the 5’ R and the region just upstream (5’ U3) contains sites which bind cellular factors and trigger transcription, known as TBS. Retroviruses may become endogenous when they infect germ cells, being transmitted throughout generations. In this review we have used the algorithm ALGGEN to analyze the presence of TBS in the U3 region of both endogenous and exogenous retroviruses. Exogenous retroviruses have included different gammaretroviruses (gibbon ape leukemia virus, GALV; murine leukemia virus, MuLV; koala retrovirus, KoRV and feline leukemia virus, FeLV). Endogenous retroviruses studied were related to FeLV (enFeLV). The most abundant TBS found were related to the immune response (adaptive and innate). Many TBS were arranged in clusters combining six or more overlapping sites, and polymorphisms mostly occurred outside the TBS. The number of TBS was similar in most LTRs analyzed. The analysis of TBS may explain the pathogenesis of each viral type. The high degree of conservation of TBS in endogenous sequences supports their importance.

Abstract

This study investigated the growth performance parameters and parasites of Colossoma macropomum farmed in an aquaponic system constructed semi-dry wetland. Fingerling of C. macropomum (8.3 ± 0.9 g) were stocked in three experimental densities: 334, 668 and 1,002 g m− 3 g using four replicates by each treatment. The initial weight of C. macropomum was similar between fish densities tested. Electrical conductivity, nitrite, nitrate, potassium, and magnesium, turbidity, phosphate, total ammonia, and alkalinity increased with fish density. Dissolved oxygen concentrations showed a reduction, reflecting on fish growth. The final weight was different and that it was negatively impacted with increased density. The specific growth rate was similar between treatments with 334 and 668 g m− 3, but it differed significantly from treatment with and 1,002 g m− 3 of fish. The mean weight gain decreased with increased of fish density, while feed conversion ratio increased. Relative condition factor and survival of fish were not affected by the densities of fish. Ichthyophthirius multifiliis, Anacanthorus spathulatus, Notozothecium janauachensis and Mymarothecium boegeri were parasites found on C. macropomum gills in low abundance, which was not influenced by different densities of fish. Our results showed that fish yield was negatively impacted with increased density and differed between the by different density of fish, while the sanity was not affected.
Dynamic Interlining in Bus Operations
Authors: Zahedi Seyedmostafa , Koutsopoulos Haris N. , Ma Zhenliang 
Published: January 2023

Abstract
The paper introduces and evaluates the concept of the dynamic interlining of buses. Dynamic interlining is an operational strategy for routes with a terminal station at a common hub, allowing a portion of (or all) the fleet to be shared among the routes belonging to the hub (shared fleet) as needed. The shared fleet is dispatched on an on-demand basis to serve scheduled trips on any route to avoid delays and regulate services. The paper examines systematically the impacts of dynamic interlining on service reliability. It formulates the dispatching problem as an optimization problem and uses simulation to evaluate the dynamic interlining strategy under a variety of operating conditions. Using bus routes in Boston’s Massachusetts Bay Transportation Authority (MBTA) as a case study, the strategy’s feasibility and factors that affect its performance are investigated. Results show that dynamic interlining can improve service reliability (increases on-time departures and decreases departure headways variability at the hub). The fraction of the fleet that is shared has the most dominant impact on performance. In the case where all buses are dynamically interlined, the performance improves as route frequency increases and more routes participate in the strategy.
Laser Directed Energy Deposition of CoCrFeNiTi High Entropy Alloy Coatings: Effects of Powder Geometry and Laser Power
Authors: Li Yunze , Zhang Dongzhe , Hu Yingbin , Cong Weilong 
Published: January 2023

Abstract
CoCrFeNiTi high entropy alloy (HEA) has been extensively studied to serve as coating materials on complexly shaped parts of equipment used in industries such as oil, gas, and mining due to its high hardness, excellent wear resistance, and good high-temperature stability. Laser directed energy deposition has potential to fabricated HEA caotings due to its advantages of excellent metallurgical bonding, high coating density, suppressed element segregation, and the capability of thick coating deposition. However, limited investigations have been conducted on the effects of input parameters (such as powder geometry and laser power) on the mechanical properties of laser DED fabricated CoCrFeNiTi high-entropy alloy coatings. In this study, CoCrFeNiTi HEA coatings have been fabricated on Ti substrates from spherical-shaped and irregular-shaped powders under different levels of laser power. The effects of powder geometry and laser power on molten pool thermal characteristics (including temperature, cooling rate, and solidification time), phase constitution, microstructure, and mechanical properties of hardness and wear resistance have been investigated. Under the same laser power, the utilization of irregular-shaped powders resulted in uniform microstructures and higher hardness. For the coatings fabricated from spherical-shaped powders, the increase of laser power could improve the microhardness and wear resistance. For the coatings fabricated from spherical-shaped powders, the increase of laser power could increase the microhardness. However, the wear resistance is increased and then decreased due to the increase in friction of coefficient.
Negentropy: a sustainable culture of educational leadership. An OCAI model analysis
Authors: Covaci Mihai , Covaci Brîndușa 
Published: January 2023

Abstract
Purpose: This study aims to analyze the impact of socio-economic negentropy on a management organization's culture. The study aims to check the level of entropy within an organization and propose solutions for negentropy development. The excellent organization represents the ordering of positive entropy into negative entropy.
Design/methodology/approach: The theoretical part of the paper presents the importance of the negentropy paradigm in developing the management organization's culture. The empirical study is based on samples from a university with information about different management organization cultures. The data are analyzed by means of regression analysis applied to the Organizational Culture Assessment Instrument (OCAI). The organizational culture improves management organization through socio-economic negentropy.
Findings: Four types of organizational cultures were determined for socio-economic negentropy applied to management organizations: group/family/clan/human relations, ad-hoc/in development/ innovation/open system, hierarchical/internal process/rules-based, rational/market/goal-based. The model has theoretical limitations, being applied to a few respondents. Practical implications refer to the improvement of management organization cultures through using negentropy. Possible social impact concerns a superior work organization and increased productivity. The assumed hypotheses show that the variables' level of education, seniority, age, and job position generate valid statistical models for the existing/preferred cultures from the OCAI model.
Originality: Organizations with coherent management efficiently organize their activities through an entropic management organization model. Present within an organization (as an open system), negentropy opposes disintegration, disorder, and entropy.

Abstract

Introduction: Psychological stress is associated with major adverse cardiovascular events (MACE). The objective of this systematic review (SR) is to evaluate the effect of nonpharmacological psychological stress management interventions on MACE and mortality in patients with coronary artery disease (CAD).
Methods: SR and meta-analysis of randomized clinical trials (RCTs) of adult patients with CAD undergoing nonpharmacological psychological stress management interventions. MEDLINE, Cochrane, LILACS, PsycInfo, Clinical Trials databases and gray literature were used for the search. There were no limits regarding publication status, year, or language. The analyzed outcome was a combination of MACE (cardiovascular mortality, nonfatal infarction, revascularization, nonfatal stroke, and cardiovascular hospitalization). The secondary outcomes were total mortality. Results were expressed as risk ratio (RR) with their 95% confidence interval (CI95%). The random effects model was used for the analyses, the RoB2 tool to risk of bias and RStudio for the statistical analyses. Prospective International Register of Systematic Reviews (CRD42021275198).
Results: This SR included seven RCTs (n = 1908). There was no effect attributable to the intervention on reducing MACE (34.54% vs 39.05%; RR= 0.84 [CI95% 0.63–1.12], p = 0.24; PI95% 0.35–2.02; I2 = 74.7%, p = 0.001) or on the analysis of isolated events. The intervention reduced the risk of total mortality by 37% (8.58% vs 13.62%; RR= 0.63 [CI95% CI 0.42– 0.95], p = 0.03; PI95% 0.18–2.25; I2 = 23.8%, p = 0.27).
Conclusion: This meta-analysis showed no significant decrease in psychological intervention for stress management in MACE, but a significant decrease in mortality.

Abstract
Cushing’s disease is a rare neuroendocrine disorder with excessive endogenous cortisol, impaired cognition, and psychiatric symptoms. Evidence from resting-state fMRI revealed the abnormalities of static brain connectivity in patients with Cushing’s disease (CD patients). However, it is unknown whether the CD patients’ dynamic functional connectivity would be abnormal and whether the dynamic features are associated with deficits in cognition and psychopathological symptoms. Here, we evaluated 50 patients with Cushing’s disease and 57 healthy participants by using resting-state fMRI and dynamic functional connectivity (dFNC) approach. We focused on the dynamic features of default mode network (DMN), salience network (SN), and central executive network (CEN) because these are binding sites for the cognitive-affective process, as well as vital in understanding the pathophysiology of psychiatric disorders. The dFNC was further clustered into four states by k-mean clustering. CD patients showed more dwell time in State 1 but less time in State 4. Intriguingly, group differences in dwell time in these two states can explain the cognitive deficits of CD patients. Moreover, the inter-network connections between DMN and SN and the engagement time in State 4 negatively correlated with anxiety and depression but positively correlated with cognitive performance. Finally, the classifier trained by the dynamic features of these networks successfully classified CD patients from healthy participants. Together, our study revealed the dynamic features of CD patients’ brains and found their associations with impaired cognition and emotional symptoms, which may open new avenues for understanding the cognitive and affective deficits induced by Cushing’s disease.

Published: January 2023

Abstract

A Maturity Model (MM) is needed to improve and operate globally. Even though a laboratory has been accredited for more than 20 years but no evidence to prove that the system was mature for competing internationally. Many commercial laboratories were business-oriented companies; MM was supposed to be used to measure the success of their processes and management styles. The improvement was based on 4M (Manpower, Method, Machine, Material) to enhance the operations and help understand the different maturity levels and how MM can benefit the organisation. The MM was developed based on analytes accurate certain score (AACS) for the ten most routine testing and system maturity scores (SMS), which cover overall proficiency testing performance and audit/assessment scores for the recent two cycles. The models do not fix inefficiencies; they can identify areas where organisations are not operating at standard and allow them to determine strategies to improve their operations and processes. This study was based on a commercial laboratory named ABC (not a real name), which was accredited in early 1990 and went through 8 cycles of assessments. The maturity model was applied to this laboratory and fell in the “leading” level with a total score above 80%. However, improvement is needed for better development, which are 1. Manpower: maintain competent staff by changing the management’s strategy. 2. Method: validate all the in-house methods following Analytical Laboratory Accreditation Criteria Committee (ALACC) guidelines. 3. Machine: apply good laboratory practice (GLP) for equipment sharing, specifically the equipment for a specific analyte. 4. Material: Metrological traceable reference material (RM) needed, involvement Proficiency Testing (PT) in all analytes.
Real-World Approach for Evaluating Capacity Fading in Lithium-ion Batteries Using Novel Cyclic Testing Methods
Authors: Mulpuri Sai Krishna , Sah Bikash , Kumar Praveen 
Published: January 2023

Abstract
Battery lifespan estimation is an essential aspect of battery management systems. It allows end users and original equipment manufacturers to plan for future battery replacements. However, accurately estimating the capacity of a battery is complex due to the different capacity fading phenomenon which are related to different factors such as temperature, charge-discharge rate, rest period duration, etc. A realistic cyclic testing method is needed to evaluate the life span, as it lets the users assess various factors’ impacting battery performance over time. Different cyclic testing methods are proposed in the literature; however, the most efficient approach will depend on the specific application and the testing objectives. A new approach, closer to real-world driving scenarios, is proposed in this work for battery capacity fading evaluation. A deeper comprehension of the results helps develop an empirical relation appropriate to evaluate capacity fading at given testing conditions easily.
