Changes in axial length in anisometropic children wearing orthokeratology lenses.

Purpose: There is a particular anisometropia occurring in one eye with myopia, while the other eye has very low myopia, emmetropia, or very low hyperopia. It is unclear how the binocular axial length changes when these children wear unilateral OK lenses only in the more myopic eyes. This study investigates the changes in the axial elongation of both eyes.

Permeability-Engineered Compartmentalization Enables In Vitro Reconstitution of Sustained Synthetic Biology Systems.

In nature, biological compartments such as cells rely on dynamically controlled permeability for matter exchange and complex cellular activities. Likewise, the ability to engineer compartment permeability is crucial for in vitro systems to gain sustainability, robustness, and complexity. However, rendering in vitro compartments such a capability is challenging.

Hydrogel Microparticles Functionalized with Engineered as Living Lactam Biosensors.

Recently there has been an increasing need for synthesizing valued chemicals through biorefineries. Lactams are an essential family of commodity chemicals widely used in the nylon industry with annual production of millions of tons. The bio-production of lactams can substantially benefit from high-throughput lactam sensing strategies for lactam producer screening.

An Efficient and Robust Framework for SAR Target Recognition by Hierarchically Fusing Global and Local Features.

Automatic target recognition (ATR) of synthetic aperture radar (SAR) images is performed on either global or local features. The global features can be extracted and classified with high efficiency. However, they lack the reasoning capability thus can hardly work well under the extended operation conditions (EOCs).

Examination of parental effect on the progeny diapause by reciprocal cross test in the cabbage beetle, Colaphellus bowringi.

The cabbage beetle, Colaphellus bowringi Baly (Coleoptera: Chrysomelidae), a serious pest of crucifers in China, undergoes summer or winter diapause in the soil as an adult. In the present study, the incidence of diapause were measured in reciprocal crosses between a high-diapause strain (HD strain) and a laboratory-selected nondiapausing strain (ND strain) under different photoperiods and temperatures, to explore parental influences on the progeny diapause. Sensitivity to photoperiod in the selected nondiapausing strain was nearly eliminated at 25 °C, whereas sensitivity to temperature of the selected nondiapausing strain was retained under continuous darkness at 20 and 22 °C.

Bis[2-(2-pyridyl-sulfan-yl)eth-yl]ammonium perchlorate.

The cation and anion of the title salt, C(14)H(18)N(3)S(2) (+)·ClO(4) (-), lie on a twofold rotation axis. The cation is a W-shaped entity with the aromatic rings at the ends; the ammonium NH(2) (+) group is a hydrogen-bond donor to the pyridyl N atoms. The perchlorate ion has one O atom disordered over two sites in a 0.

Bis[2-((4,6-dimethyl-pyrimidin-2-yl){2-[(4,6-dimethyl-pyrimidin-2-yl)sulfan-yl]eth-yl}amino)-eth-yl] disulfide.

Bis[2-(4,6-dimethyl-pyrimidin-2-ylsulfan-yl)eth-yl]amine under hydro-thermal conditions has unexpectedly been transformed into the title compound, C(32)H(44)N(10)S(4). In the title mol-ecule, the zigzag 3,10-diaza-6,7-disulfanyldodecyl skeleton has two dimethyl-pyrimidinylsulfanyl groups at both ends, and the aza atoms each carry a dimethyl-pyrimidinyl unit. The N atoms in the skeleton show a planar coordination.

3-[2-(1,3-Benzothia-zol-2-ylsulfan-yl)eth-yl]-1,3-oxazolidin-2-one.

The title compound, C(12)H(12)N(2)S(2)O(2), consists of a benzothia-zole group and a oxazolidin-1-one linked via a flexible ethane-1,2-diyl spacer. The benzothiazole group and the oxazolidine ring are each almost planar [with maximum deviations of 0.007 (2) and 0.
