Self-assembly by anti-repellent structures for programming particles with momentum.

Self-assembled configurations are versatile for applications in which liquid-mediated phenomena are employed to ensure that static or mild physical interactions between assembling blocks take advantage of local energy minima. For granular materials, however, a particle's momentum in air leads to random collisions and the formation of disordered phases, eventually producing jammed configurations when densely packed. Therefore, unlike fluidic self-assembly, the self-assembly of dry particles typically lacks programmability based on density and ordering symmetry and has thus been limited in applications.

In Situ Programmable, Active, and Interactive Crystallization by Localized Polymerization.

Additive manufacturing has sought active and interactive means of creating predictable structures with diverse materials. Compared to such active manufacturing tools, current crystallization strategies remain in statistical and passive programs of crystals via macroscale thermodynamic controllers, commonly lacking active means to intervene in crystal growth in a spatiotemporal manner. Herein, a strategy toward active and interactive programming and reprogramming of crystals, realized by real-time tangible feedback on growing crystals by delicately controlling the degree of in-situ, localized photopolymerization of polymeric structures via additive manufacturing is presented.

Modified Periosteal Releasing Incision (MPRI) for Primary Closure: Visualization of the Mental Nerve.

Periodontal procedures often require flap advancement for adequate coverage of the surgical site, with tension-free primary closure essential for successful outcomes. Although the periosteal releasing incision is frequently performed, it may necessitate deeper or more incisions, which could result in consequences such as edema, bleeding, paresthesia, and discomfort for the patient. To address these issues, the modified periosteal releasing incision was proposed to minimize trauma into the submucosa.

Fully Transparent and Distortion-Free Monotonically Stretchable Substrate by Nanostructure Alignment.

Stretchable devices, garnering increasing attention as next-generation form factors, have a crucial problem in that vertical contraction occurs during stretching, causing image distortion of stretchable displays and discomfort in skin-attached devices. Previous structural strategies to mitigate vertical contraction, such as auxetic reentrants and wrinkles, suffer from the drawback that their structure becomes visible during stretching. In this study, this issue is addressed by unidirectionally aligning nanoscopic cylinders within block copolymer elastomer films.

Investing in Custodial Grandparents: Cost Analysis of the Social Intelligence Program.

Rising child welfare costs and a desire to keep kids out of the system have encouraged the use of kinship care-of which custodial grandparents make up the majority of caregivers. Unfortunately, custodial grandparents report greater needs for social and emotional support to successfully care for their grandchildren. Yet, the resources required to provide preventive social-emotional support to these families are unknown.

Hypoxia increases methylated histones to prevent histone clipping and heterochromatin redistribution during Raf-induced senescence.

Hypoxia enhances histone methylation by inhibiting oxygen- and α-ketoglutarate-dependent demethylases, resulting in increased methylated histones. This study reveals how hypoxia-induced methylation affects histone clipping and the reorganization of heterochromatin into senescence-associated heterochromatin foci (SAHF) during oncogene-induced senescence (OIS) in IMR90 human fibroblasts. Notably, using top-down proteomics, we discovered specific cleavage sites targeted by Cathepsin L (CTSL) in H3, H2B and H4 during Raf activation, identifying novel sites in H2B and H4.
