Dissipative Landau-Zener tunneling in the crossover regime from weak to strong environment coupling.

Landau-Zener tunneling, which describes the transition in a two-level system during a sweep through an anti-crossing, is a model applicable to a wide range of physical phenomena. Realistic quantum systems are affected by dissipation due to coupling to their environments. An important aspect of understanding such open quantum systems is the relative energy scales of the system itself and the system-environment coupling, which distinguishes the weak- and strong-coupling regimes.

Wound infection rate after skin closure of damage control laparotomy with wicks or incisional negative wound therapy: An EAST multi-center trial.

Damage control laparotomy (DCL) has a high risk of SSI and as an attempt to mitigate this, surgeons often leave the skin open to heal by secondary intention. A recent retrospective study showed that DCL wounds could be closed with the addition of wicks or incisional wound vacs with acceptable rates of wound infection. The aim of this prospective trial was to corroborate these results.

Failure rates of nonoperative management of low-grade splenic injuries with active extravasation: an Eastern Association for the Surgery of Trauma multicenter study.

Objectives: There is little evidence guiding the management of grade I-II traumatic splenic injuries with contrast blush (CB). We aimed to analyze the failure rate of nonoperative management (NOM) of grade I-II splenic injuries with CB in hemodynamically stable patients.

Methods: A multicenter, retrospective cohort study examining all grade I-II splenic injuries with CB was performed at 21 institutions from January 1, 2014, to October 31, 2019.

Elevated transferrin receptor impairs T cell metabolism and function in systemic lupus erythematosus.

T cells in systemic lupus erythematosus (SLE) exhibit multiple metabolic abnormalities. Excess iron can impair mitochondria and may contribute to SLE. To gain insights into this potential role of iron in SLE, we performed a CRISPR screen of iron handling genes on T cells.

Effects of Color Attributes on Trap Capture Rates of Chrysobothris femorata (Coleoptera: Buprestidae) and Related Species.

Chrysobothris spp. (Coleoptera: Buprestidae) and other closely related buprestids are common pests of fruit, shade, and nut trees in the United States. Many Chrysobothris spp.
