In recent years,various gene-edited crops and livestock have been developed to find rapid and unconventional solutions to boost agriculture,animal breeding,environmental sustain-ability,and animal welfare.In the animal production field,significant gene-edited livestock with economic beneficial traits,like the MSTN-edited double muscles,can be com-mercialized on a large scale to benefit more people with real need.Nutritional demand for animal proteins increases an-nually with improvement of living conditions in modern societies and developing countries.Additionally,the number of people with special needs for healthier meat(with high-protein and low-fat)is growing(e.g.,elderly patients with cardio/cerebrovascular diseases).With steady global en-vironmental deterioration,increasing human population,growing food demand,continuous disease outbreaks,and concerns regarding animal welfare。

We introduce a new class of semigroups called strict abundant semigroups,which are concordant semigroups and subdirect products of completely-J*-simple abundant semigroups and completely-J*-simple primitive abundant semigroups.A general construction and a tree structure of such semigroups are established.Consequently,the corresponding structure theorems for strict regular semigroups given by Auinger in 1992 and by Grillet in 1995 are generalized and extended.Finally,an example of strict abundant semigroups is also given.

The total effective spin-exchange relaxation of naturally abundant Rb in a K–Rb–21Ne comagnetometer is analyzed,and the results show that the coexistence of 87Rb and 85Rb isotopes in the same volume can lead to a large extra spinexchange broadening compared to pure 87Rb.This broadening mainly comes from the contribution of the equivalent reduction in the Rb spin-exchange rate.On this basis,an approximate relaxation model is proposed and experimentally demonstrated to be more accurate than that from a previous work.This study also provides a method for determining the properties of alkali-metal vapor cells.

Galloylglucoses can extensively and intensively interact with proteins and possess many biological activities and exhibit optimal health benefits.A novel galloylglucose had been observed and separated from fresh shoots of some special tea genetic resources,and was characterized as a trigalloylglucose isomer with mass parent ion[M-H]−at m/z 635.10 and daughter ions at m/z 483.08,465.08,313.02 and 168.98 and with UV absorbance peaks at 221 nm and 278 nm after being measured with UPLC-DAD-MS/MS.The trigalloylglucose was highly purified by semipreparative chromatography and identified as 1,4,6-tri-O-galloyl-β-glucopyranose(1,4,6-TGG)by 1H-NMR,13C-NMR,H1-H1 COSY and HMQC.Antioxidant capacity of the 1,4,6-TGG was 2.68−5.77μmol TEAC/μmol,and significantly higher(42.7%−419.4%)than that of ascorbic acid,but similar to another well-known powerful antioxidant epigallocatechin gallate in tea,indicating that 1,4,6-TGG could,in the future,be applied in the development of functional foods and pharmaceuticals.

INTRODUCTION Preservation of the freshwater resources is a big challenge for a healthy civilized world.Although water consumption increased more than twice the population increase rate,drinking water pollution and freshwater shortage increased dramatically during the last decades(Kar et al.,2012;Mueller and Nowack,2010).Only 0.01%of freshwater resources are suitable for human needs(Rashid et al.,2019),even in the areas of abundant freshwater(Yeston et al.,2006).By 2050,over 5 billion of the world population will be under severe fresh water supply conditions due to climate change and urbanization exacerbate(Sealy,2019;Oves et al.,2015;Kar et al.,2012).Currently,one billion people drink unhygienic water,especially in developing countries which leads to severe waterborne diseases which might cause death(Aminiyan et al.,2018).Twelve million people die every year due to this problem(Zhao et al.,2019;Oves et al.,2015).

Viruses are the most diverse and abundant type of biological entity on Earth,infecting species from all of life’s domains and being found in almost all types of environments.They are gaining increasing attention from scientists,officials and the public due to recent major outbreaks with human health consequences(e.g.,AIDS,SARS,COVID-19)and a growing appreciation of the impact viruses have had on the long-term development of both the biosphere and geosphere.The ability to identify viruses in ancient times is of importance in promoting our understanding of viral evolution and the relationships of viruses to their hosts and to paleoclimate conditions,enabling predictions of present and future impacts of the virosphere on life and the climate system.

Recent deep-diving expeditions in the South China Sea(SCS)discovered abundant indigenous cold-water corals[1].Cold-water corals,preferentially inhabiting the low-latitude intermediate and deep waters with hard substrates and a cool water temperature,have great potential to be applied in researches of the ocean interior by providing high-resolution records[2,3].

THE ~15N NMR study is of general interest in the analysis of the protein conformations in solu-tions. When NMR is applied to the conformation study of macrobiomolecules, a heteronuclearmultiple quantum coherence (HMQC) spectrum of ~15N is usually measured first, so that theamide protons are assigned before other experiments, such as the total correlation

Globular clusters(GC)are among the oldest celestial bodies in the Milky Way.Typically possessing millions of stars and have been going through abundant stellar interactions,GCs are futile ground for hunting for compact objects,particularly,neutron stars.A significant number of fast-spinning millisecond pulsars(MSPs)have been discovered,comprising the majority of known GC pulsars.
