Article Abstract
ZrO2-based resistive switching memory has attracted much attention according to its possible application in the next-generation nonvolatile memory. The Al/ZrO2/Pt resistive switching memory with bipolar resistive switching behavior is revealed in this work. The thickness of the ZrO2 film is only 20 nm. The device yield improved by the non-lattice oxygen existing in the ZrO2 film deposited at room temperature is firstly proposed. The stable resistive switching behavior and the long retention time with a large current ratio are also observed. Furthermore, it is demonstrated that the resistive switching mechanism agrees with the formation and rupture of a conductive filament in the ZrO2 film. In addition, the Al/ZrO2/Pt resistive switching memory is also possible for application in flexible electronic equipment because it can be fully fabricated at room temperature.

Genomic insights into a diarrheal outbreak in Bangladesh reveal novel ETEC lineages and expansion of CS23 colonization factor.

Enterotoxigenic (ETEC), a leading cause of diarrhea, is defined by heat-stable (ST) and/or heat-labile (LT) toxins and associated colonization factors (CFs). However, there is still a knowledge gap in understanding ETEC's evolution, particularly in endemic regions like Bangladesh. This study investigates the genomic attributes contributing to the rise of ETEC-associated diarrhea in Bangladesh during 2022-2023.

Neuromorphic Visual Devices hold considerable promise for integration into neuromorphic vision systems that combine sensing, memory, and computing. This potential arises from their synergistic benefits in optical signal detection and neuro-inspired computational processes. However, current devices face challenges such as insufficient light/dark resistance ratios, mismatched transient photo-response, and volatile retention characteristics, limiting their adaptability to complex artificial vision systems.

African swine fever virus (ASFV) is a large DNA virus that causes a highly lethal disease in pigs and currently has no effective vaccines or antiviral treatments available. We designed a protein switch that combines the DNase domain of colicin E9 (DNase E9) and its inhibitor Im9 with the viral protease cleavage site. The complex is only destroyed in the presence of an ASFV pS273R protease, which releases DNase activity.

Recalcitrant palmar common warts pose a considerable challenge in dermatology due to their frequent persistence despite various treatment attempts. The thick stratum corneum of the palms and the constant pressure and friction in this location contribute to their resistance to therapy and a high rate of recurrence. We report the case of a 33-year-old male with a 26-month history of a progressively enlarging palmar wart refractory to extensive conventional therapies, including 18 intermittent sessions of liquid nitrogen cryotherapy administered over the course of his 26-month history, two electrofulguration sessions, and various topical agents.
