Microplastics may lose buoyancy and occur in deeper waters and ultimately sink to the sediment and this may threaten plankton inhabiting in various water layers and benthic organisms. Here, we conduct the first survey on microplastics in the water column

Effect of Column Pressure on Column Efficiency
Nature, 1964IN a recent communication given by Amos and Hurrell1, the authors stated that it was difficult to obtain high efficiencies or adequate resolving power, when packed 0.25-in. external diameter (4 mm internal diameter) analytical chromatographic columns were used in association with thermal conductivity detectors.

C-Store: A Column-oriented DBMS
Very Large Data Bases Conference, 2005This paper presents the design of a read-optimized relational DBMS that contrasts sharply with most current systems, which are write-optimized. Among the many differences in its design are: storage of data by column rather than by row, careful coding and

In this quarter's column, Stephen Brookes and Peter O'Hearn describe how Concurrent Separation Logic (CSL) arose, including a little about the soundness proof and a discussion of later developments that arose from CSL.

The stability phenomenon of a structure is defined by its state of equilibrium. The equilibrium of a designed structure is stable if small imperfections or defects will cause correspondingly small deviations from the idealized operating condition.

Clinics in Podiatric Medicine and Surgery, 2020
Lower extremity biomechanics is the cornerstone of podiatric medicine and surgery. The foot and ankle act as the interface between the ground and proximal segments, mediating internal and external moments Although the medial longitudinal arch has been widely researched, the details of the lateral longitudinal arch are less extensively delineated.

Many verification problems can be formulated as a language inclusion problem where the task is to decide whether the language of the system model (given by the runs of the system) is contained in the language induced by a logical specification. The corresponding verification problem for non-functional properties is the quantitative inclusion problem ...

Campus Security Report
I was chatting with my youngest son the other day while driving him to wrestling practice and playing “Daddy Uber.” I mentioned to him that I needed to work on writing my column, and he asked me what it was about. I mentioned I had a few ideas, but there were so many things going on in higher education, many that I have written extensively about, that ...
