“…[376,377] Domain phenomena are utilized in MM layers, with MTJ configurations exhibiting a single domain and minimized programming variability. Due to precessional switching, conventional VCMA MTJ configurations reveal high programming error rates, [378,379] whereas a small programming error rate throughout a large temperature range is disclosed in the case of STT MTJ configurations.

Separate memory and processing units are utilized in conventional von Neumann computational architectures. However, regarding the energy and the time, it is costly to shuffle data between the memory and the processing entity, and for data‐intensive applications associated with artificial intelligence, the demand is ever increasing. A paradigm shift in traditional architectures is required, and in‐memory computing is one of the non‐von‐Neumann computing strategies. By harnessing physical signatures of the memory, computing workloads are administered in the same memory element. For in‐memory computing, a wide range of memristive material (MM) systems have been examined. Moreover, developing computing schemes that perform in the same sensory network and that minimize the data shuffle between the processing unit and the sensing element is a requirement, to process large volumes of data efficiently and decrease the energy consumption. In this review, an overview of the switching character and system signature harnessed in three archetypal MM systems is rendered, along with an integrated application survey for developing in‐sensor and in‐memory computing, viz., brain‐inspired or analogue computing, physical unclonable functions, and random number generators. The recent progress in theoretical studies that reveal the structural origin of the fast‐switching ability of the MM system is further summarized.

The electromagnetic force used in electromagnetic forming is mainly divided into attraction and repulsion. Dual-coil attractive electromagnetic forming can be used in the field of sheet pit repair. However, the magnetic field and eddy current generated by the two coils compete with each other, and the energy utilization rate is low. Therefore, a compensation coil is introduced, and an electromagnetic forming scheme of a three-coil dual-power sheet based on mixed force is proposed and verified by simulation. It is found that the three-coil mixed force can effectively improve the competition between the magnetic field and eddy current. The loading of the mixing force is not a simple superposition of attraction and repulsion, but the mutual promotion of the two. The forming displacement of the three-coil mixed force forming scheme is 582% higher than that of the dual-coil attraction forming scheme, and 89% higher than that of the attract first and then repel forming scheme. The forming effect of the three-coil mixing force is related to the number of turns of the compensation coil. The research results can improve the energy utilization rate of electromagnetic forming and provide a new idea for the loading scheme of electromagnetic forming force field.

The most common comorbidities associated with the increased severity of COVID-19 were hypertension, diabetes, obesity, and cardiovascular diseases [ 8 ]. Several variants of SARS-CoV-2 have emerged that are notable because of their potential for increased transmission [ 9 ].…”

The COVID-19 pandemic, caused by SARS-CoV-2, has profoundly affected developing countries like India. This retrospective cross-sectional analysis investigated epidemiological, clinical characteristics, treatment strategies, and outcomes for hospitalized COVID-19 patients during the Massive SARS-CoV-2 Wave in India. Among 233 patients, the median age was 47.33 years, mostly male. Hospital stays averaged 8.4 days. Common symptoms include fever (88.41%), dry cough (56.2%), myalgia (44.20%), and shortness of breath (22.8%). The most common comorbidities were diabetes mellitus (52%) and hypertension (47.2%). Elevated biomarkers include D-dimer (24.4%), CRP (32.1%), ferritin (26.60%), and others. Prescription analysis revealed that antibiotics (42.6%), Antivirals (37%), anthelmintics (20.30%), vitamins and nutritional supplements (20.71%) and glucocorticoids (12.8%) were the most commonly prescribed. Oxygen therapy was needed by 19.31% of patients in the moderate and severe categories within 24 hours of admission. The mortality rate was 8.58%. The surge led to increased hospitalizations and mortality, particularly among young adults. Diabetes and hypertension were correlated with mortality. Irregular use of drugs lacking evidence, like antibiotics and anthelmintics, vitamins and nutritional supplements, was observed in COVID-19 management. This study underscores the impact of the pandemic in India and highlights the need for evidence-based treatments.
