The combination of the chiral tecton based on the (R)-6,6'-dibromo-1,1'-binaphthyl moiety bearing two isonicotinoyl groups with AgX (X = BF4-, CF3SO3-, PF6-) leads to the formation of enantiomerically pure helical strands with orthogonal packing in the rare space group I2(1)3.

Oligopool synthesis and next-generation sequencing enable the construction and characterization of large libraries of designed genetic parts and systems. As library sizes grow, it becomes computationally challenging to optimally design large numbers of primer binding sites, barcode sequences, and overlap regions to obtain efficient assemblies and precise measurements. We present the Oligopool Calculator, an end-to-end suite of algorithms and data structures that rapidly designs many thousands of oligonucleotides within an oligopool and rapidly analyzes many billions of barcoded sequencing reads.

In real-life complex traffic environments, vehicles are often occluded by extraneous background objects and other vehicles, leading to severe degradation of object detector performance. To address this issue, we propose a method named YOLO-OVD (YOLO for occluded vehicle detection) and a dataset for effectively handling vehicle occlusion in various scenarios. To highlight the model attention in unobstructed region of vehicles, we design a novel grouped orthogonal attention (GOA) module to achieve maximum information extraction between channels.

Red kidney beans (RKB) serve as a powerhouse packed with a plethora of largely unexplored extraordinary chemical entities with potential significance. However, their nutraceutical applications as a functional hypoglycemic food still lag behind and warrant further investigation. With a scope to optimize chemical and biological traits of RKB, green modification approaches (processing methods) seem inevitable.

Two new [1-(phenyl-sulfon-yl)-1-indol-2-yl]methanamine derivatives, namely, -(3-meth-oxy-phen-yl)--{[1-(phenyl-sulfon-yl)-1-indol-2-yl]meth-yl}acetamide, CHNOS, (), and -(2,5-di-meth-oxy-phen-yl)--{[1-(phenyl-sulfon-yl)-1-indol-2-yl]meth-yl}benzene-sulfonamide, CHNOS, (), reveal a nearly orthogonal orientation of their indole ring systems and sulfonyl-bound phenyl rings. The sulfonyl moieties adopt the anti-periplanar conformation. For both compounds, the crystal packing is dominated by C-H⋯O bonding [C⋯O = 3.

Photonic heterostructures with codable properties have shown great values as versatile information carriers at the micro- and nanoscale. These heterostructures are typically prepared by a step-by-step growth or post-functionalization method to achieve varied emission colors with different building blocks. In order to realize high-throughput and multivariate information loading, we report here a strategy to integrate polarization signals into photonic heterojunctions.
