Native electrospray-ionization mass spectrometry (native MS) measures biomolecules under conditions that preserve most aspects of protein tertiary and quaternary structure, enabling direct characterization of large intact protein assemblies. However, native spectra derived from these assemblies are often partially obscured by low signal-to-noise as well as broad peak shapes because of residual ...

Abstract Two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC × GC-TOFMS) is a powerful tool for identification of compounds in complex samples. Herein, we compared the GC GC-TOFMS and systems polar metabolite profiling rice seeds. Forty-seven thirty-six metabolites were detected Korean cultivar, Dongjin, using GC-TOFMS, respectively. The limits detection shikimic,...

Optical phonons in nanoparticles with the randomness of interatomic bonds are considered both analytically and numerically. For weak dilute disorder two qualitatively different regimes separated overlapped levels observed, resembling case random atomic masses investigated previously. At stronger and/or more dense disorder, particles become essentially inhomogeneous, thus constituting minimal mo...

Dong and Zhao (1) attempt to provide perspective on our use of Raman spectroscopy in plant stress studies (2). Unfortunately, their experimental criticism is incorrect and their technical suggestions won’t work. The following points support these strong statements. Dong and Zhao claim that Raman spectroscopy is limited by its “poor repeatability” (1). Our experimental data speak for themselves,...

The effects of excitatory inputs arising from Ia afferent and corticomotoneuronal volleys on repetitively firing flexor carpi radialis (FCR) motoneurons were compared in normal human subjects. Peripheral (Ia) volleys were produced by transcutaneous electrical stimulation of the median nerve and by mechanical taps to the FCR tendon. Transcranial magnetic stimulation (TMS) was used to activate th...

Abstract The complex crystallization behavior of the Zr 40 Ti 15 Cu 10 Ni Be 25 bulk metallic glass (BMG) produced by suction-casting method was studied with non-isothermal DSC measurements heating rate from 5 to K/min. Three exothermic phenomena were observed for investigated material. novel evaluation procedure qualitative and quantitative analysis intricate kinetics Zr-based BMGs is proposed...

In this letter, we propose a novel precoding scheme for base station (BS) cooperation in downlink cellular networks that allow overlapped clusters. The proposed precoding scheme is designed to mitigate the overlapping-BS interference by maximizing the so-called clustered virtual signal-to-interferenceplus-noise ratio (SINR). Simulations show that with the proposed scheme, overlapped clustering ...

Chromosomes are essential genomic information carriers. The identification of chromosome abnormalities is an essential part of diagnosis and treatment of genetic disorders such as chromosomal syndromes and many types of cancer. There are different types of chromosome aberration like mapping of the common duplications, deletions, and translocations. One of the most considerations in the field of...
