We demonstrate the preparation of heralded Fock-basis qubits (a|0〉+b|1〉) from transient collective spin excitations in a hot atomic vapor. The preparation event is heralded by Raman-scattered photons in a four-wave mixing process seeded by a weak coherent optical excitation. The amplitude and phase of the seed field allow arbitrary control over the qubit coefficients. The qubit state is charact...

روانگرایی در ماسه های ریزدانه اشباع در هنگام زلزله، موجب خرابی سازه های زیادی در نقاط مختلف دنیا بوده است. از عوامل موثر در این پدیده می توان به تراکم خاک، دانه بندی خاک، عمق لایه مورد نظر و تنش های موثر همه جانبه، شدت و مدت زمان زمین لرزه و درصد عبوری از الک شماره 200 (مقدار ریزدانه و جنس آن) اشاره نمود. عالباً در روشهای رایج ارزیابی وقوع روانگرایی از خصوصیات درجای خاک، همانند نتایج آزمایش های ...

Native grasses are increasingly popular and valuable tools for revegetation, erosion control, and wildlife habitat improvement. Many have unique features and benefits that make them advantageous over certain exotic and introduced grasses. In the field of ecological restoration, they are a critical and required component of the target plant community, ecosystem, or natural habitat. A number of n...

A field experiment was conducted at Cotton Research Station, Nanded (M.S.) India during kharif season of 2019 and 2020 to study effect moisture conservation practices fertilizer levels on earliness Bt cotton under rainfed condition. The trial with hybrid NHH 44 (BG II) in split plot design replicated thrice. Four treatments (M1- flat bed, M2- opening furrow 60 DAS, M3- application superabsorben...

An improvement in the previously reported seed-mediated chemical synthesis of gold nanorods (GNRs) is reported. Monodisperse GNRs have been synthesized in a one-step protocol. The addition of controlled quantity of sodium borohydride (NaBH4) directly into the growth solution produced uniform GNRs, formed by in situ nucleation and growth. In order to arrive at the conclusion, we studied the form...

This study the effect of seed preparation (priming) with different concentrations of hydrogen peroxide on the anatomy of the flag leaf and spike two wheat genotypes( Cross Sabalan ( bread wheat) and Saji(durum wheat)) and its relationship with grain yield, under dry land farming system condition, Experimental design was factorial, arranged in randomized complete block. Results showed that the n...

Limited time for crop residue decomposition and complete seedbed preparation in double-cropping necessitates reduced tillage which is associated with its shortcomings. Information about seedbed preparation aspects in double-cropping of wheat and mungbean in Isfahan is lacking. For this reason, the effects of various seedbed preparation methods on growth, seed yield and yield components of mungb...

Understanding the regulatory networks coordinating seed development will help to manipulate seed traits, such as protein content and seed weight, in order to increase yield and seed nutritional value of important food crops, such as legumes. Because of the cardinal role of the nucleus in gene expression, sub-proteome analyses of nuclei from developing seeds were conducted, taking advantage of t...

OBJECTIVES 1) To evaluate and compare the stability of two types of implants in an animal model after preparing the implant bed with various sequences of osteotomes in bone type IV. 2) To evaluate the hypothesis of whether or not the sequence of using osteotomes influences the primary implant stability. MATERIAL AND METHOD We selected bone from cow ribs, which in its cross section (the most m...

This paper describes our approaches for the preparation of gazetteers for named entity recognition (NER) in Indian languages. We have described two methodologies for the preparation of gazetteers1. Since the relevant gazetteer lists are more easily available in English we have used a transliteration based approach to convert available English name lists to Indian languages. The second approach ...
