Abstract: A lithium secondary battery with improved lifetime characteristics, a driving method thereof, a battery module including the same, and a battery pack including the battery module, provides the lithium secondary battery having an operating voltage that is less than a plateau voltage of the lithium/nickel composite oxide, and thus has an advantage of being enable to prevent the lithium/nickel composite oxide from being transferred to a spinel-like structure, suppress the capacity degradation according to an increase in cycle, and improve a lifetime characteristic.

Abstract: Many people have died in their homes in their sleep while suffering from COVID-19 infection. This invention proposes a patient and caregiver bracelet system by which patient breathing and heart rate status declines are monitored through pulse oximetry connected to their bracelets and caregivers sleeping in the same house are alerted via their own caregiver bracelets. The underlying communications signaling can be sent via wireless digital technology and also via radio frequency.

Abstract: During the progression of atherosclerosis, autoantibodies are induced to epitopes of oxidized low-density lipoprotein (OxLDL), and active immunization of hypercholesterolemic mice with OxLDL ameliorates athero-genesis. The present studies have identified anti-OXLDL autoantibodies that share complete genetic and structural identity with antibodies produced by anti-phosphorylcholine B-cell clone, T15.
