#Occupywallstreet: An Analysis of Twitter Usage during a Protest Movement

In 2011, the Occupy Wall Street movement made history as one of the largest grassroots protest events in the United States. Members made frequent use of social media tools, like Twitter, to share information and mobilize participants. This study uses content analysis to examine the way that Twitter is used to incite, organize, and perpetuate protest movements. 1500 tweets in total were coded for content and linguistic features to provide insight into how Twitter is used to achieve different goals surrounding protest movements, the tonality of the tweets, and the purpose of distributed messages. Our findings indicate that Twitter is a tool primarily used for sharing objective, logistical information, along with opinions, to create a unified community and mobilize individuals to participate in a physical space of protest.

Competitive Occupying of Fe^3+ and Co^3+ Ions into the Lattice B-Sites of Perovskite Crystalline Structure

Perovskite-type oxide has a general formula ABO3. Both the lattice A- and lattice B-sites can be occupied by two kinds of metallic ions, forming substituted perovskites such as La（1-x）SrxCoO3-d and LaFexCo（1-x）O3. In the present work, we aim to investigate competitive occupying of Fe（3＋） and Co（3＋） ions into the lattice B-sites of perovskite LaFexCo（1-x）O3 formed under the condition of excess feeding of Fe（3＋） and Co（2＋） ions relative to the La（3＋） ions. For this purpose, standard curve of normalized cell volumes（NCVs） of a defined series of perovskites LaFexCo（1-x）O3 versus the x values was plotted. Lattice occupancy of Fe（3＋） ions at the B-sites of the perovskite LaFexCo（1-x）O3 was then determined from the standard curve. It is proved that Fe（3＋） ions were capable of occupying preferentially into the lattice B-sites of the perovskite crystalline structure.

A new gnetalean macrofossil from the Lower Cretaceous of the Laiyang Basin, eastern China

Gnetophytes are a key group of plant for understanding seed plant phylogeny,partly because of their unique and elusive morphology,such as xylem with vessels,phloem with chaperones,reticular veins,and double fertilization(Endress,1996).In particular,the ovule bears a membranous integument,the upper part of which extends beyond the seed envelope to form a micropylar tube.Therefore,gnetophytes occupy a unique evolutionary position in the phylogeny of seed plants and apparently represent a transition between angiosperms and other gymnosperms(Ran et al.,2018).Modern gnetophytes consist of only three families:Ephedraceae,Gnetaceae,and Welwitschiaceae,and each family contains only one genus.Ephedraceae(Ephedra L.)are the earliest diverging group of Gnetales,with a total of 70 extant species,and usually occur in cold and arid places in Asia,Europe,northern Africa,western North America and South America(Price,1996;Yang et al.,2017b).

Strong electron correlation-induced Mott-insulating electrides of Ae_(5)X_(3)(Ae=Ca,Sr,and Ba;X=As and Sb)

The presence of interstitial electrons in electrides endows them with interesting attributes,such as low work function,high carrier concentration,and unique magnetic properties.Thorough knowledge and understanding of electrides are thus of both scientific and technological significance.Here,we employ first-principles calculations to investigate Mott-insulating Ae_(5)X_(3)(Ae=Ca,Sr,and Ba;X=As and Sb)electrides with Mn_(5)Si_(3)-type structure,in which half-filled interstitial electrons serve as ions and are spin-polarized.The Mott-insulating property is induced by strong electron correlation between the nearest interstitial electrons,resulting in spin splitting and a separation between occupied and unoccupied states.The half-filled antiferromagnetic configuration and localization of the interstitial electrons are critical for the Mott-insulating properties of these materials.Compared with that in intermetallic electrides,the orbital hybridization between the half-filled interstitial electrons and the surrounding atoms is weak,leading to highly localized magnetic centers and pronounced correlation effects.Therefore,the Mott-insulating electrides Ae_(5)X_(3)have very large indirect bandgaps(0.30 eV).In addition,high pressure is found to strengthen the strong correlation effects and enlarge the bandgap.The present results provide a deeper understanding of the formation mechanism of Mott-insulating electrides and provide guidance for the search for new strongly correlated electrides.

A Story About a King of Scotland

I read a story from an interesting book.The story said that once there was a king in Scotland whose name was Robert Bruce.His homeland was occupied by the king of England.He was driven out of his land.He tried six times to fight back but failed.One rainy day,he was tired and sick.When he lay on the ground and was ready to give up,he saw a spider over his head.Six times the spider tried to throw its thread.

Two More Fragmentary Folios from the Book of Zambasta?

The Book of Zambasta(abbreviated‘Z’)is a long poem in Old Khotanese which has been described as’a veritable Manual of Buddhism’.[1]The best-preserved copy,sometimes referred to as‘Z1’,seems to have formed part of a manuscript miscellany,in which the 24 chapters of Z occupied folios 143 verso to 440 recto.Of these 298 folios,more than two thirds are still extant in whole or part.In Z1each verse is written on a single line,with six lines to the page.The text is presented in four columns separated by spaces which in principle correspond to the caesurae between the four padas(‘abcd’)of the verse.The verse number is frequently indicated at the end of the line,often in abbreviated form(e.g.‘2’in place of‘52’,or‘52’in place of‘152’).

Domestic Beauty Makeups Saying Good-bye to“Hurricane Dash”

The year 2022 is a rough patch for domestic beauty makeups.When major overseas brands have occupied the first echelon of the area list on each major platform,new domestic brands have no confidence to take COVID-19 pandemic as a fig leaf for the stagnant sales volume.Some professional managers find pessimistically that Generation Z groups,which new brands take as main clients,should have turned to grand brands without hesitation.A severe fact has been placed before the Chinese beauty makeup market-the marketing method that domestic cosmetics rely on for starting up is no longer a secret key for competition,and it seems very difficult for the weak product power to resist the overwhelming grand brands.

Water lilies as emerging models for Darwin’s abominable mystery

Water lilies are not only highly favored aquatic ornamental plants with cultural and economic importance but they also occupy a critical evolutionary space that is crucial for understanding the origin and early evolutionary trajectory of flowering plants.The birth and rapid radiation of flowering plants has interested many scientists and was considered‘an abominable mystery’by Charles Darwin.In searching for the angiosperm evolutionary origin and its underlying mechanisms,the genome of Amborella has shed some light on the molecular features of one of the basal angiosperm lineages;however,little is known regarding the genetics and genomics of another basal angiosperm lineage,namely,the water lily.In this study,we reviewed current molecular research and note that water lily research has entered the genomic era.We propose that the genome of the water lily is critical for studying the contentious relationship of basal angiosperms and Darwin’s‘abominable mystery’.Four pantropical water lilies,especially the recently sequenced Nymphaea colorata,have characteristics such as small size,rapid growth rate and numerous seeds and can act as the best model for understanding the origin of angiosperms.The water lily genome is also valuable for revealing the genetics of ornamental traits and will largely accelerate the molecular breeding of water lilies.

Review of Finger millet(Eleusine coracana(L.)Gaertn):A power house of health benefiting nutrients

The bulk of the world’s millet crop is produced by India,Nigeria,Niger,Mali,Burkina Faso,Chad,and China.Finger millet(Eleusine coracana(L.)Gaertn),little millet(Panicum sumatrense Roth ex Roem.&Schult.),foxtail millet(Setaria italica(L.)P.Beauvois)and proso millet(Panicum miliaceum L.)are most commonly found species among various millet varieties.In India,finger millet occupy the largest area under cultivation among the small millets.Finger millet stands unique among the cereals such as barley,rye and oats with higher nutritional contents and has outstanding properties as a subsistence food crop.It is rich in calcium(0.34%),dietary fiber(18%),phytates(0.48%),protein(6%–13%)minerals(2.5%–3.5%),and phenolics(0.3%–3%).Moreover,it is also a rich source of thiamine,riboflavin,iron,methionine,isoleucine,leucine,phenylalanine and other essential amino acids.The abundance of these phytochemicals enhances the nutraceutical potential of finger millet,making it a powerhouse of health benefiting nutrients.It has distinguished health beneficial properties,such as anti-diabetic(type 2 diabetes mellitus),anti-diarrheal,antiulcer,anti-inflammatory,antitumerogenic(K562 chronic myeloid leukemia),atherosclerogenic effects,antimicrobial and antioxidant properties.

The View of Chinese Culture and the Imbalance of Cultural Industry’s development from “Nezha: Birth of the Demon Child”

“Nezha:Birth of the Demon Child”has been popular all over China in the summer of 2019,which is a milestone in the development of China's cultural industry.Since the reform and open policy,foreign cultures and cultural industries have taken root and sprouted in China.There are more and more audience groups in China.The age and scope of the audience are more and more wide,which enriches the spiritual life of Chinese people.However,the local culture and cultural industry need to be developed and protected.Today,with the economic globalization,multi polarization of international politics and more frequent exchanges among countries around the world,how to make our own culture and cultural industry occupy a place in the national spiritual world,and play out the signboard of“Chinese culture”,make Chinese culture and cultural industry“blossom everywhere”,and make more and more people in the world identify with Chinese culture and culture Industry will eventually build China into a socialist cultural superpower with strong economy and technology.There is still a long way to go.In this paper,we will discuss the potential and problems of cultural development in China.

Magnetic quantum oscillation in a monolayer insulator

The Shubnikov-de Haas(Sd H)oscillation,as evidenced by the oscillating resistivity as a function of magnetic field at sufficiently low temperature,is not uncommon in metals,semimetals and narrow gap semiconductors at their conducting state.The origin of Sd H oscillation is associated with Landau quantization,at which the cyclotron orbits of electrons are quantized.In other words,electrons can only occupy discrete energy levels,which are called the Landau levels.As the magnetic field increases,the split,quantized Landau levels move across the Fermi level and hence the material’s transport properties start to oscillate periodically.

Time-Dependent Behavior in Arrays of Two Coupled Quantum-Dot Cells

Time-dependent behavior of two kinds of arrays of two coupled quantum-dot cells is examined.Each square cell composed of four quantum dots in the corners contains two electrons and couples with the neighboring cells by Coulomb interactions.The electrons in one cell tend to occupy antipodal dots which results in a cell apolarizationtf.We have investigated the temporal evolution of the polarization of one cell under switch of the polarization of the other cell.Our results demonstrate that,with an adiabatic switch,if two cells are arranged in a line their polarizations will align each other,and if they are arranged in a diagonal way their polarizations will invert each other.However,with an abrupt switch,the above/features for the polarizations of two cells can not hold.The reason is that the system does not stay in its ground state.It is pointed out that the energy dissipation should be considered in order to obtain the appropriate solutions.
