We present a novel new way-called Schrödingerization-to simulate general (quantum and nonquantum) systems of linear ordinary and partial differential equations (PDEs) via quantum simulation. We introduce a new transform, referred to as the warped phase transformation, where any linear-including nonautonamous-system of ordinary or partial differential equation can be recast into a system of Schrödinger's equations, in real time, in a straightforward way. This approach is not only applicable to PDEs for classical problems but is also useful for quantum problems, including the preparation of quantum ground states and Gibbs thermal states, the simulation of quantum states in random media in the semiclassical limit, simulation of Schrödinger's equation in a bounded domain with artificial boundary conditions, and other non-Hermitian physics.

Diamond-Blackfan anemia syndrome (DBAS) is an inherited bone marrow failure disorder caused by haploinsufficiency of ribosomal protein genes, most commonly RPS19. Limited access to patient hematopoietic stem/progenitor cells (HSPCs) is a major roadblock to developing novel therapies for DBAS. We developed a novel self-inactivating third-generation RPS19-encoding lentiviral vector (LV), termed "SJEFS-S19", for DBAS gene therapy.

Article Synopsis
  • Adverse Childhood Experiences (ACEs) are linked to cognitive disabilities, with frequent mental distress (FMD) potentially playing a mediating role in this relationship.
  • A study analyzing data from 10,309 young adults (ages 18-25) found that about 71.6% had experienced ACEs, and 15.8% reported cognitive disabilities.
  • The research showed that individuals with ACEs and those reporting FMD had significantly higher risks of cognitive disability, suggesting that experiencing more types of ACEs increases the risk and that FMD mediates this relationship.

Aerosols significantly affect the transmission of optical signals in the atmosphere, necessitating accurate atmospheric models for the performance evaluation of electro-optic devices. Aerosol size distribution is a critical parameter in these models, and the lognormal function is commonly used to mathematically represent it. This study aims to handle the lack of a solid criterion for determining the number of lognormal modes and introduces an improved scheme that leverages the characteristics of the second derivative (SD) of the Gaussian curve to identify the mode amount and to initialize mode parameters for fitting.

Two Co-based supramolecular isomers were synthesized from a fluorinated carboxylic acid ligand under hydrothermal conditions at varying temperatures. Both exhibited similar one-dimensional chain structures while different bending connections of the aromatic rings led to different supramolecular structures, namely CoCP-1 and CoCP-2, respectively. The structural differences of two isomers resulted in discrepant performance with regards to luminescence sensing and catalysis.
