We have observed the effect of pseudomagnetic field originating from polaritonic analog spin-orbit coupling [transverse electric and transverse magnetic (TE-TM) splitting] on a polariton condensate in ring-shaped microcavity. The gives rise to stable four-leaf pattern around ring as seen linear polarization measurements photoluminescence. This is found originate interplay cavity potential, ener...

Patients with traumatic pelvic ring injury may represent an immense challenge for the emergency physician. First, patients with pelvic ring fractures are at risk for exsanguinating pelvic hemorrhage. Furthermore, the profound magnitude of force required to disrupt the pelvic ring frequently causes severe injuries to other organ systems. The resuscitation from hemorrhagic shock, rapid identifica...

microwave assisted green synthesis of α, ά- bis (substituted- benzylidene) alkanones by the crossed- aldol condensation reaction of substituted aryl aldehydes with ketones in the presence of catalytic amount of nbcl5 in good to excellent yields. this reaction is carried out under solvent-free conditions. the results showed that aldehydes bearing electron–donating substituent's on phenyl-ring fa...

Asynchronous packet-switched interconnection networks with decentralized control are very appropriate for multiprocessing and data flow architectures. This paper presents performance models of single and multiple ring networks based on token ring, slotted ring, and register insertion ring protocols. The multiple ring networks have the advantages of being reliable, expandable, and cost effective...

Aziridines can undergo a range of ring-opening reactions with nucleophiles. The regio- and stereochemistry of the products depend on the substituents on the aziridine. Aziridine ring-opening reactions have rarely been used in radiosynthesis. Herein we report the ring opening of activated aziridine-2-carboxylates with [(18)F]fluoride. The aziridine was activated for nucleophilic attack by substi...

stable crystalline phosphorus ylides are obtained in excellent yields from the 1:1:1 addition reactionbetween hydantoins or thiohydantoins and dialkyl acetylenedicarboxylates in the presence oftriphenylphosphine. these phosphoranes undergo smooth intramolecular wittig reaction followedby an electrocyclic ring opening to produce dialkyl (e)-2-(2,5-dihydro-5,5-diaryl-2-thioxo-1h-imidazol-4-yl)fum...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study the infiltration parameters were evaluated in real conditions of a center pivot system. for this purpose a single ring with ...

‎let $r$ be a ring with involution $*$‎. ‎an additive mapping $t:rto r$ is called a left(respectively right) centralizer if $t(xy)=t(x)y$ (respectively $t(xy)=xt(y)$) for all $x,yin r$‎. ‎the purpose of this paper is to examine the commutativity of prime rings with involution satisfying certain identities involving left centralizers.
