The study determined the effectiveness of reading modules using the Marungko approach for grade one pupils in selected elementary schools in Zambales, Philippines, during the school year 2020-2021. The study revealed that the pupil-participant is a typical male young pre-schooler, whose parent is a housekeeper and living in the inner town proper. The pupils in the controlled and experimental groups were assessed under frustration level in decoding of words, reading speed and reading comprehension in the first pre-test assessment. The pupils-participant in the controlled and experimental groups were assessed under frustration level in decoding of words, reading speed and reading comprehension in the second pre-test assessment. The pupil-participant in the first post-test assessment, the controlled group were assessed "Instructional level" in decoding of words, slow in reading speed and frustration in the reading comprehension. For the experimental groups assessed independent is decoding of words, fast in speed of reading and independent in reading comprehension. The pupil-participant in the second post-test assessment, the controlled group were assessed "Instructional level" in decoding of words, slow in reading speed and frustration in the reading comprehension. For the experimental groups assessed independent is decoding of words, average in speed of reading and independent in the reading comprehension. The academic performance of the pupil-participants was "Satisfactory". There is significant difference on the results between pre-test and post-test assessment in the experimental group after being expose to Marungko Approach.

Published: June 2022

AbstractChimeric antigen receptors (CAR) redirect T cells to specifically recognize and eliminate tumor cells. CAR‐T therapy has achieved successful clinical outcomes, and it has been transformed into commercially available products to treat acute lymphoblastic leukemia and B cell lymphoma. These breakthroughs have motivated hundreds of CAR‐T clinical trials initiated each year, with ≈900 cases registered on the ClinicalTrials website till 2021. Accumulating clinical experiences have highlighted some limitations of this strategy, e.g., relapse after complete response, poor efficacy in solid tumors, on‐target off‐tumor toxicities, lack of persistence, and tumor resistance. These challenges limit the therapeutic application of CAR‐T cells. Multidisciplinary approaches are actively investigated to address these issues. In this review, the antigens, CAR designs, and cell sources are summarized in clinical trials from 2020 to 2021. The innovative modular and programmable designs in CAR‐T cells, including advances in signaling domains, antigen‐recognition domains, T cell engineering, and cell resources, are further discussed. Integrative genetic and chemical engineering strategies are promising to improve the versatility, antitumor efficacy, persistence, and safety of CAR‐T cells. In the future, the next generation of CAR‐T cell therapies will offer more options for patients who are refractory to standard tumor therapies.
Continual Learning Electrical Conduction in Resistive‐Switching‐Memory Materials

Published: June 2022

AbstractThe authors apply the concept of continual learning to modeling conductive‐filament growth in resistive‐switching materials (RSM). The approach permits computation of compliance current without knowing the geometries of conductive filaments and switching behaviors. This avoids the need to retrain the entire dataset when additional compliance currents are considered and is thus ideal for resistive switching (RS) thin films, doped layers, and other material systems. Computation of compliance current is consistent with experimental data for a wide range of parameters and learning tasks and demonstrates switching behavior not captured by traditional models. Lesion calculations elucidate the brain‐inspired‐modification‐facilitated increase in compliance‐current‐computation‐accuracy. A state‐of‐the‐art performance on challenging compliance‐current learning tasks without storing data is achieved (“brain inspired replay (BIR) – gating based on internal context (Gat)” method, ≈89%; above a benchmark of ≈50% for synaptic‐intelligence (SI)/elastic‐weight‐consolidation (EWC) methods), and it provides a novel model for computing compliance current based on replay of the brain. This intuitive approach combined with a simple solver tool, allows researchers with little computation experience to perform realistic and accurate modeling.
Dynamically Responsive Scaffolds from Microfluidic 3D Printing for Skin Flap Regeneration
Authors: Wang Xiaocheng , Yu Yunru , Yang Chaoyu , Shang Luoran , Zhao Yuanjin , Shen Xian 
Published: June 2022

AbstractBiological scaffolds hold promising perspectives for random skin flap regeneration, while the practical application is greatly limited by their insufficient vascularization ability and the lack of responsiveness during the dynamical healing process. Herein, a novel MXene‐incorporated hollow fibrous (MX‐HF) scaffold with dynamically responsive channels is presented for promoting vascularization and skin flap regeneration by using a microfluidic‐assisted 3D printing strategy. Benefiting from the photothermal conversion capacity of the MXene nanosheets and temperature‐responsive ability of poly(NIPAM) hydrogels in the MX‐HF scaffolds, they display a near‐infrared (NIR)‐responsive shrinkage/swelling behavior, which facilitates the cell penetration into the scaffold channels from the surrounding environment. Moreover, by incorporating vascular endothelial growth factor (VEGF) into the hydrogel matrix for controllable delivery, the MX‐HF scaffolds can achieve promoted proliferation, migration, and proangiogenic effects of endothelial cells under NIR irradiation. It is further demonstrated in vivo that the NIR‐responsive VEGF@MX‐HF scaffolds can effectively improve skin flap survival by promoting angiogenesis, decreasing inflammation, and attenuating apoptosis in skin flaps. Thus, it is believed that such responsive MX‐HF scaffolds are promising candidates for clinical random skin flap regeneration as well as other diverse tissue engineering applications.
Immunogenic Cell Death Activates the Tumor Immune Microenvironment to Boost the Immunotherapy Efficiency

Published: June 2022

AbstractTumor immunotherapy is only effective in a fraction of patients due to a low response rate and severe side effects, and these challenges of immunotherapy in clinics can be addressed through induction of immunogenic cell death (ICD). ICD is elicited from many antitumor therapies to release danger associated molecular patterns (DAMPs) and tumor‐associated antigens to facilitate maturation of dendritic cells (DCs) and infiltration of cytotoxic T lymphocytes (CTLs). The process can reverse the tumor immunosuppressive microenvironment to improve the sensitivity of immunotherapy. Nanostructure‐based drug delivery systems (NDDSs) are explored to induce ICD by incorporating therapeutic molecules for chemotherapy, photosensitizers (PSs) for photodynamic therapy (PDT), photothermal conversion agents for photothermal therapy (PTT), and radiosensitizers for radiotherapy (RT). These NDDSs can release loaded agents at a right dose in the right place at the right time, resulting in greater effectiveness and lower toxicity. Immunotherapeutic agents can also be combined with these NDDSs to achieve the synergic antitumor effect in a multi‐modality therapeutic approach. In this review, NDDSs are harnessed to load multiple agents to induce ICD by chemotherapy, PDT, PTT, and RT in combination of immunotherapy to promote the therapeutic effect and reduce side effects associated with cancer treatment.
Sustainable agricultural production, income, and eco‐labeling: What can be learned from a modern Ricardian approach?
Authors: Heerman Kari E. R. , Sheldon Ian M. 
Published: June 2022

AbstractIn this article, trade‐in sustainably produced agricultural products with eco‐labeling are modeled using a modern Ricardian framework. Based on this approach, expressions are derived for the share of products importers purchase from specific exporters for low‐cost unsustainable and high‐cost sustainable production technologies, assuming consumers have non‐homothetic preferences. The consumer and sustainability gains from eco‐labeling are also analyzed, along with a discussion and comparison of the effects of mutual recognition versus harmonization of countries' eco‐labeling regimes.
Few‐Copy Entanglement Detection in the Presence of Noise
Authors: Saggio Valeria , Walther Philip 
Published: June 2022

AbstractAlthough the realization of useful quantum computers poses significant challenges, swift progress in emerging quantum technologies is making this goal realistically approachable. In this context, one of the essential resources is quantum entanglement, which allows for quantum computations outperforming their classical counterparts. However, the task of entanglement detection is not always straightforward for several reasons. One of the main challenges is that standard methods rapidly become unfeasible when dealing with quantum states containing more than a few qubits. Typically, this is due to the fact that a vast number of measurements are needed on many copies of the state. Generally, it is not unusual to deal with a very limited number of state copies in experimental settings—in fact, this may be the case for many large quantum systems. In this article, an overview is provided of a probabilistic approach that enables high‐confidence genuine multipartite entanglement detection using an exceptionally low number of state copies. Additionally, a study is presented that shows that this protocol remains efficient also in the presence of noise, thus confirming the practicality of the method for near‐term quantum devices and its suitability for complex experimental settings.
In situ encapsulation of ZrQ in UiO‐66 (Zr‐BDC) for pore size control to enhance detection of a nerve agent simulant dimethyl methyl phosphonate
Authors: Wong Danny , Kim Seonghwan , Abuzalat Osama 
Published: June 2022

Chemical warfare agents are toxic chemicals that require rapid, easy‐to‐use, sensitive, and selective sensors to countermeasure. Simulants, such as dimethyl methyl phosphonate (DMMP), are used to test the effectiveness of sensors toward nerve agents. Metal organic frameworks (MOFs) offer large surface area and selective accessibility to active sites making them appealing for chemical sensing applications. In this work, we propose a fast, facile, direct synthesis method for manufacturing fluorescent MOFs with high sensitivity and selectivity. Zr‐BDC is synthesized with 1, 4‐benzenedicarboxylic acid (BDC) as an organic ligand and zirconium (Zr) metal. Fluorescent materials are then encapsulated in a novel and rapid in situ approach with strong solvents. X‐ray diffraction, UV–visible spectroscopy, Fourier‐transform infrared spectroscopy, and Raman spectroscopy are used to verify the successful formation of fluorescent MOFs. Compared to other methods, the gel synthesis method helps to control crystal growth leading to higher BET surface areas of ~1150 m2 g−1 for Zr‐BDC and 850 m2 g−1 for ZrQ@Zr‐BDC. Titration experiments show the sensitivity of the material to DMMP down to 8.3 nM with a highly linear response. Enhanced fluorescence and occupation of mesopores by ZrQ enable lower limit of detection than those of comparable works in literature. The encapsulation mechanism also prevents substantial defects that would otherwise lead to water adsorption.
Influences of fiber fibrillation degree on mechanical and tribological performances of aramid fiber/nitrile rubber composites

Published: June 2022

AbstractThree types of aramid fibers (AFs) with various surface fibrillation degrees were introduced into nitrile rubber (NBR) matrix to prepare the AF/NBR composites, respectively. Their impacts on the mechanical and tribological performances of the NBR composites were mainly studied. The results showed that, as the fiber content increased, the tensile strength of the AF/NBR composites increased after initially decreased, and the turning point moved toward the direction of lower AF content with the fiber fibrillation degree increase. In addition, when the AF content was low, the tensile strength decreased as the fibrillation degree increased, but the opposite trend was observed when the AF content became high. In addition, the tear strength increased with the increase of the fiber content and fibrillation degree. With the fiber fibrillation degree increase, the tan δmaxof the composites decreased, indicating a stronger restriction on the NBR molecular chains. Furthermore, the surface fibrillation degree increase slightly decreased the friction coefficient (COF). The wear performance of the AF/NBR composites improved with the fiber content increase. The fibrillation degree increase further improved the wear resistance. It should be due to the tear strength increase and the enhanced interfacial interaction between the fiber and rubber matrix.

Published: June 2022

AbstractLinz‐Donawintz (LD) slag is a solid waste produced during the basic oxygen furnace process of steel making and is more often disposed of on nearby land causing a disturbance in vegetation and human health. Hence, judicial management of LD slag is a need for an hour. For this purpose, the usability of LD slags as a reinforcement material in epoxy composites was investigated in the present work. In this investigation, the physical properties (density, void content, water absorption rate), mechanical properties (tensile properties, flexural properties, compressive strength, hardness), and tribological properties (sliding wear behavior) are reported. From the experimental investigation, it is found that the density, void content, and water intake capacity increase with LD slag loading. The maximum voids present in the composite is 1.92% for epoxy/40 wt. % LD slag composite. Similarly, maximum water uptake of only 0.6% is observed for composite with maximum filler content and for maximum immersion time. Further, it is observed that the strength of composite under tensile and flexural loading was compromised slightly. At 40 wt. % of LD slag, the measured tensile and flexural strength are 20.8 MPa and 28.78 MPa respectively. The strength of composites under compressive loading increases with filler content and reaches a maximum of 108 MPa for epoxy/40 wt. % LD slag composite. The high hardness of filler assists in increasing the hardness of the composites. The hardness of neat epoxy is Shore‐D number 75 which increases to Shore‐D number 84. With increased hardness, ultimately the specific wear rate under dry sliding conditions reduces. Taguchi's L25 orthogonal array having four factors, each at five different levels is implemented to conduct the sliding wear tests. A forecast model is built on an artificial neural network (ANN) which successfully envisages the sliding wear performance of the composite under investigation inside and outside the experimental domain.
