Mitral regurgitation in conduction disorders is a rare feature of functional valve regurgitation.
In patients with high-grade atrioventricular block, the onset of ventricular ejection may shift with atrial telesystole; in this case, the rise in left ventricular filling pressure after atrial systole, especially in the case of complete atrioventricular block leading to an inversion of the LA-LV gradient during the supraventricular relaxation phase and diastolic mitral insufficiency can gradually set in , as well as secondary tricuspid regurgitation
Here we report the observation of a patient admitted for a complete atrioventricular block, with reversible mitral and tricuspid regurgitation after implantation of a pace maker.

The present study examined the effect of foliar spray of humic acid on root Growth, yield components and quality in Redgram (Cajanus cajan ).The study was conducted during Kharif 2015-16 at Main Agricultural Research Station, UAS, Raichur by using randomized block design. The effectiveness of humic acid was studied with different levels as T1 - Humic acid liquid 15% @ 1.0 ml/l of water, T2 - Humic acid liquid 15% @ 1.5 ml/l of water, T3 - Humic acid liquid 15% @ 2.5 ml/l of water, T4 - Humic acid liquid 15% @ 4.0 ml/l of water, T5 - Planofix 4.5 % @ 20ppm and T6 - as a control. Redgram root growth including root length, shoot length, root dry weight , shoot dry weight , leaf area, dry matter production, flower drops, minerals content (quality), and yield components were measured at 60,90 DAS and at harvest, respectively. Significant differences (p<0.05) were observed for all the above mentioned parameters across the humic acid levels. Based on this study, the foliar application T4-Humic acid liquid 15% @ 4.0 ml/l of water might be recommended to improve growth physiology, quality and yield components of Redgram in similar environmental conditions. Further, research is required in diverse plant environments to determine economically feasible application levels of Humic acid while comparing it with other plant growth regulators sources.

Published: March 2022

Background: Female breast cancer (BC) has surpassed lung cancer as the most prevalent reason for cancer-related diagnosis in the world. BC has geographical disparities in the intensity of effect of its associated risk factors on patients’ survival. Several models can be employed to determine the effect of risk factors on patients’ survival. The present study aims at evaluating these models.
Methods: The secondary data of 558 BC patients diagnosed at Korle Bu teaching hospital during 2010-2015 and followed-up (right censored) to the end of 2015 were analysed. The survival status, demographic and tumour characteristics of these patients were determined by event history analysis. To compare various models of survival, Akaike Information Criterion (AIC) , Bayesian Information Criteria (BIC) and Receiver Operation Characteristic (ROC) curve were used. R software was used for data analyses. The data consisted of BC patients in the age range of 13 to 97 years. The dataset was partitioned into training (holding 70%) and validation set (30%).
Results: Based on AIC, BIC and ROC curve values the Gompertz (AIC=2322, BIC=2391) was the best model fit for the survival data. Generalised Gamma (AIC=2378, BIC=2451) and Weibull (AIC=2382, BIC=2452) models were respectively the next alternatives among the nine (9) accelerated failure time (AFT) models considered in our study. Results from the three best fitted AFT models showed that covariates such as Age at diagnosis, Progesterone receptor, Molecular Subtype, Grade, Stage, Metastasis, number of Lymph nodes involved and genetic status were the significant factors that have an effect on the survival time of BC patients in Ghana (P<0.05). The Area under the ROC curve (AUC=0.945) shows an outstanding performance of the Gompertz AFT model to discriminate the true disease status of patients.
Conclusion: Although the Cox proportional hazard model has seen wide usage and remains a robust approach in survival analyses for the past four decades; its proportional hazards assumption is most often violated by some covariates in medical research. Under such violations, AFT models are a strong alternative.

Background: Since few years finite element (FE) analysis has turn out to be a widespread tool for investigators seeking to simulate the tooth biomechanics and associated structures. Finite element method plays important role to expand understanding of the ferrule effect. This paper contains a systematic review and conclusions from FE method grounded computational simulations of the the tooth with post and core to simulate function and tissue behavior
Methods: 14 applicable papers were linked within this systematic literature search. Uprooted data contained information on type of tooth, location of tooth, magnitude of force, software used for modelling, boundary condition, method of scanning, validation, tooth with ferrule, tooth without ferrule, key findings.
Results: Included papers illustrated use of FE analysis for replication of including nonlinear tooth and tissue mechanics, contact analysis and rigid body movements. We executed multi-database systematic review through PRISMA standards accomplishing inclusion criteria and results were investigated and précised for appropriate papers.
Discussion: With prompt expansions of computer knowledge, the FEA now recognized as a potent method in dental biomechanics due to its flexibility in measuring stress dispersals within multidimensional structures. The researcher will be well equipped to understand the results of FEA investigations and correlate these results to clinical settings after learning the basic theory, application, method, and limitations of FEA in dentistry. Ferrule has a precarious impact on stress reduction. Teeth are less stressed when posts and cores are composed of strong materials. Keeping supragingival tooth structure included within the crown gives repaired teeth extraordinary strength.

Objectives: Acinetobacter baumannii is an opportunistic bacterial pathogen with intrinsic and acquired resistance to many antibiotics, resulting in high morbidity and mortality. This study aimed to detect MDR Acinetobacter baumannii and its resistant genes (blaNDM, blaOXA48) from clinical isolates in Khartoum state.
Methodology: A cross-sectional hospital-based study was conducted during the period fromApril to July 2019. A total of 50 clinical isolates were obtained from samples of patients in intensive care units (ICUs) for the purpose of molecular confirming of A. baumannii and detecting NDM and OXA-48 resistance genes by using conventional PCR.
Results: Of the 50 isolates examined, 47 (94%) were confirmed to be A. baumannii, and 3 (6%) were other species. Moreover, the 47 A. baumannii isolates were furtherly examined for the presences of resistant genes and the result showed that NDM gene was detected in 2 isolates (4.3%) and OXA-48 gene was detected in only one isolate (2.1%).
Conclusion: There is low prevalence of NDM and OXA-48 Resistant Genes among A. baumannii ICUs isolates. However, continuous regional monitoring of antimicrobial resistance and improvement of infection control measures are required in the intensive care units of Khartoum hospitals to prevent further spread.

AbstractHerein, the impacts of the selective halogenation at two different positions of dicyanomethylene‐3‐indanone (IC) end groups and inner side chains of small molecular acceptors (SMAs) on the PD:SMA interfacial interactions, blend morphology, and resulting photovoltaic properties are described. In this study, four different SMAs (A1, A2, A3, and A4) with the same molecular backbone, but with different degrees of halogenation, are synthesized. The IC end groups on the backbones of the A1 and A3, and A2 and A4 SMAs are chlorinated and fluorinated, respectively; in addition, 6‐phenoxyhexyl inner side chains of the A3 and A4 are chlorinated. The SMAs are paired with a chlorinated PBDT‐Cl PD to construct organic solar cells (OSCs). The PBDT‐Cl:A4‐based OSC exhibits the highest power conversion efficiency of 17.2%, outperforming the PBDT‐Cl:A1‐(13.3%), PBDT‐Cl:A2‐(15.6%), and PBDT‐Cl:A3‐based OSC (16.5%). The Cl atoms on the side chains in the A3 and A4 SMAs enhance the molecular/energetic interactions at the PD:SMA interfaces and improve the blend morphology in terms of domain purity and spacing. These effects lead to the improved fill factors and reduced voltage loss of the PBDT‐Cl:A3‐ and PBDT‐Cl:A4‐based OSCs. This study demonstrates the importance of appropriate halogenation of SMAs in optimizing the blend morphology, reducing voltage loss, and improving OSC performance.

AbstractFluid‐bicontinuous gels are unique materials that allow two distinct fluids to interact through a percolating, rigid scaffold. Current restrictions for their use are the large fluid‐channel sizes (>5 µm), limiting the fluid–fluid interaction surface‐area, and the inability to flow liquids through the channels. In this work a scalable synthesis route of nanoparticle stabilized fluid‐bicontinuous gels with channels sizes below 500 nm and specific surface areas of 2 m2 cm−3 is introduced. Moreover, it is demonstrated that liquids can be pumped through the fluid‐bicontinuous gels via electroosmosis. The fast liquid flow in the fluid‐bicontinuous gel facilitates their use for molecular separations in continuous‐flow liquid–liquid extraction. Together with the high surface areas, liquid flow through fluid‐bicontinuous gels enhances their potential as highly permeable porous materials with possible uses as microreaction media, fuel‐cell components, and separation membranes.

Published: March 2022

AbstractVertically integrated NAND (V‐NAND) flash memory is the main data storage in modern handheld electronic devices, widening its share even in the data centers where installation and operation costs are critical. While the conventional scaling rule has been applied down to the design rule of ≈15 nm (year 2013), the current method of increasing device density is stacking up layers. Currently, 176‐layer‐stacked V‐NAND flash memory is available on the market. Nonetheless, increasing the layers invokes several challenges, such as film stress management and deep contact hole etching. Also, there should be an upper bound for the attainable stacking layers (400–500) due to the total allowable chip thickness, which will be reached within 6–7 years. This review summarizes the current status and critical challenges of charge‐trap‐based flash memory devices, with a focus on the material (floating‐gate vs charge‐trap‐layer), array‐level circuit architecture (NOR vs NAND), physical integration structure (2D vs 3D), and cell‐level programming technique (single vs multiple levels). Current efforts to improve fabrication processes and device performances using new materials are also introduced. The review suggests directions for future storage devices based on the ionic mechanism, which may overcome the inherent problems of flash memory devices.

Published: March 2022

AbstractWhilst the photocatalytic technique is considered to be one of the most significant routes to address the energy crisis and global environmental challenges, the solar‐to‐chemical conversion efficiency is still far from satisfying practical industrial requirements, which can be traced to the suboptimal bandgap and electronic structure of photocatalysts. Strain engineering is a universal scheme that can finely tailor the bandgap and electronic structure of materials, hence supplying a novel avenue to boost their photocatalytic performance. Accordingly, to explore promising directions for certain breakthroughs in strained photocatalysts, an overview on the recent advances of strain engineering from the basics of strain effect, creations of strained materials, as well as characterizations and simulations of strain level is provided. Besides, the potential applications of strain engineering in photocatalysis are summarized, and a vision for the future controllable‐electronic‐structure photocatalysts by strain engineering is also given. Finally, perspectives on the challenges for future strain‐promoted photocatalysis are discussed, placing emphasis on the creation and decoupling of strain effect, and the modification of theoretical frameworks.
The Dawn of Metamaterial Engineering Predicted via Hyperdimensional Keyword Pool and Memory Learning
Authors: Cha Young‐Ok , Hao Yang 
Published: March 2022

AbstractMetamaterials research has been ongoing for more than 20 years and it has gained much public and scientific interest. There have been many experts forecasting on the road ahead for metamaterials, notably, in lieu of “knowledge tree” in 2010. Ten years on, it is proposed to re‐examine these claims by using automated computer tools, such as natural language processing (NLP), to extract research information for processing and analyzing from unstructured texts in publications. In this study, a fully auto‐generated database of 43 678 abstracts related to metamaterials published between 2000 and 2021 using Scopus Search API (Application Programming Interface) is built. Applying word embedding, each keyword is studied in a hyperdimensional vector space and clusters so that their relationships can be visualized for assessing the popularity and trends of research themes. A neural network model developed based on the encoder–decoder long short‐term memory (LSTM) architecture is finally trained to predict future directions and theme evolutions in the next four years for selected topics. This study not only provides vital information in terms of impact of metamaterials research but also lays down a solid foundation for the development of future metamaterial research roadmap in the form of Gartner hype cycle.

Published: March 2022

AbstractPhoton‐based data communication technologies provide safe, efficient, and speedy data transfer. The conventional silicon‐based photonic circuits possess several inherent shortcomings. One of them is the mechanical rigidity of circuits. Realizing a flexible organic photonic integrated circuit (FOPIC) or organic photonic chip with functional complexity requires innovative materials and a hybrid materials platform. Mechanically flexible organic acicular crystals with fewer imperfections, high refractive index, and high quantum yield are promising materials for FOPIC fabrication. Here, the fabrication of a hybrid FOPIC using (E)‐1‐(4‐(N,N‐dimethyl)phenyl)iminomethyl‐2‐hydroxyl‐naphthalene (DPIN) and (E)‐1‐(4‐(chloro)phenyl) iminomethyl‐2‐hydroxyl‐naphthalene (CPIN) crystals for precise steering of output light at different angles is presented. The crystals of DPIN and CPIN are mechanically compliant and optically dissimilar. Mechanical micromanipulation of DPIN and CPIN flexible crystals provides a four‐port FOPIC that comprises waveguide integrated ring resonator. Mechanical maneuverability of the circuit ports enables selective routing of six bandwidth‐engineered signals at desirable angles (0–360°) in 2D. The circuit applies active/passive light‐guiding principles, reabsorbance, and energy‐transfer mechanisms for its operation. The presented proof‐of‐principle reconfigurable photonic circuit concept is advantageous in programmable circuits, navigable detectors, and intelligent sensors.

AbstractIn recent years, Förster resonance energy transfer (FRET) and related topics have received marked attention both as a subject of scientific investigation and due to its many potential applications. However, the state‐of‐the‐art matrix materials for the FRET need to be improved in terms of universal loading for all types of luminescent moieties and the matrix integrability with real‐life devices, but without sacrificing the FRET efficiency, i.e., maintaining the proximity of the embedded donors and acceptors. Amphiphilic polymer co‐networks (APCNs) are investigated as versatile matrix materials for hosting luminescent materials and realizing highly efficient FRET between hydrophobic inorganic donors (CsPbBr3 nanocrystals) and hydrophilic organic acceptors (Rhodamine B). APCNs are advantageous owing to the unique properties of their hydrophilic and hydrophobic biphasic nature and the uniformly distributed nano‐domains. The energy transfer rate can be tailored in a straightforward way by manipulating the nano‐domain sizes and volumetric distribution, so steering donor–acceptor pair loading and distances. Consequently, APCNs are used as luminescent solar concentrators for fiber solar cells, demonstrating the ability to enhance existing solar‐energy harvesting electronics via photonic energy transfer steering. APCN is demonstrated as a powerful matrix for future photonic applications in the field of energy harvesting and energy generation.
