Multiple Silicon Dangling-Bond Charge qubits for quantum computing: A Hilbert-Space Analysis of the Hamiltonian

Silicon-based dangling-bond charge qubit is one of the auspicious models for universal fault-tolerant solid-state quantum computing. In universal quantum computing, it is crucial to evaluate and characterize the computational Hilbert space and reduce the complexity and size of the computational space. Here, we recognize this problem to understand the complexity and characteristics of the Hilbert space in our dangling-bond qubit model. The size of the desired Hilbert space can prominently be reduced by considering assumptions regarding the qubit loss. Moreover, the dimension of the desired subsets in the space shrinks by a factor of two due to the spin preservation property. Finally, the required classical memory for storage of the qubit information, Hamiltonian and Hilbert space is analysed when the number of qubits grows.Comment: 8 pages, 5 figures, 2 table

EFL TEACHERS' VERBAL AND NON-VERBAL IMMEDIACY: A STUDY OF ITS DETERMINANTS AND CONSEQUENCES

Student engagement with instructors on a personal level can appear in the form of teacher’s immediacy behaviors, which includes two main kinds of immediacy, verbal and non-verbal. Ellis (2004) found when instructors display communicative behaviors similar to immediacy; students’ motivation to learn is likely to increase. Previous immediacy research has neglected to address the determinants and consequences of English as a foreign language (EFL) teachers’ immediacy behaviors. Therefore, the present study aims to investigate its determinants as well as consequences by collecting data from a number of EFL teachers and their students. The qualitative data for this study were collected via semi-structured interviews and observations. Two models emerged out of the collected data, including a) the model of the determinants of EFL teachers' immediacy which comprised body gesture, vocal variety, rapport making … b) the model of the consequences of EFL teachers' immediacy including three main categories: affective, cognitive, and perceptive domains. The results of this study showed that among the determinants of teacher immediacy, body gesture and rapport making factors exhibited the highest frequency and among the consequences factors, affective and cognitive were found to be the most frequent ones. The findings can be of particular interest to teachers, educators, and policy makers and can help them in improving the quality of teaching and providing good environment for students to learn.  Article visualizations

Quantum Sensing with Scanning Near-Field Optical Photons Scattered by an Atomic-Force Microscope Tip

Scattering scanning near-field optical microscopy (s-SNOM) is known as a promising technique for overcoming Abbe diffraction limit and substantially enhancing the spatial resolution in spectroscopic imaging. The s-SNOM works by exposing an atomic force microscope (AFM) tip to an optical electromagnetic (EM) field, while the tip is so close to a sample that the incident beam lies within the near-field regime and displays nonlinear behaviour. We suggest replacing the incident field by quantized EM fields, i.e. photons, and propose a quantum model for the suggested system, by employing electric-dipole approximation, image theory, and perturbation theory. Quantum state of scattered photons from the AFM tip is extracted from the proposed model, which contain information about electrical permittivity of the dielectric material beneath the tip. The permittivity of the sample can be extracted through spectroscopic setups. Our proposed scheme can be used for quantum imaging or quantum spectroscopy with high resolution.Comment: 4 pages and 3 figure

Spontaneous Transformation of Intramural Myoma into Peduncle During Cesarean Section in a 33-year Woman: A Case Report

We report a 33 years multipara pregnant woman who presented with vaginal bleeding due to intramural myoma and preeclampsia. After cesarean section, the myoma changed to the peduncle type and entered the internal space from the inner thickness of the uterus. This infrequent phenomenon made it easier to operate and remove the myoma within a few hours after the cesarean section. Finally, the mother and baby were discharged from the hospital safely after a few days

Predictors of local venous complications resulting from electrophysiological procedures

Background: Thromboembolic complications resulting from radiofrequency catheter ablation (RFCA) have an overall incidence of 0.6%. Multiple intracardiac catheters are often necessary for electrophysiological study and RFCA therapy. Therefore, the placement of multiple venous sheaths in one femoral vein is always required for multiple intracardiac catheter insertion. The safety of the placement of multiple separate venous sheaths has been studied previously in a non-randomized study, but the placement of multiple sheaths via one venous line has not been fully studied. Methods and Results: A randomized clinical trial was conducted with a total of 200 patients. We studied the safety of placing multiple sheaths via one venous line, and the effect of heparin on deep vein thrombosis (DVT) and on in situ thrombosis. DVT was not seen in our patients. We observed a significant decrease in the rate of in situ thrombosis in patients who received heparin during the procedure (28% vs 11%, p = 0.04). The type of cannulation changed the in situ thrombosis rate independently of the heparinization protocol. The rate of in situ thrombosis was higher when placing sheaths via one venous line regardless of the heparinization protocol used (16% vs 6%, p = 0.1 for the group on heparin, and 38% vs 18%, p = 0.04 for the other group). In the group cannulated with only one venous line (100 patients), heparinization significantly decreased the rate of in situ thrombosis (16% vs 38%, p = 0.023), but there was an insignificant decrease in the separate cannulation group (6% vs 18%, p = 0.12). Advanced age had no effect on thrombosis. Surprisingly, there was a significantly greater rate of in situ thrombosis (not DVT) among women than among men (26% vs 11%, p = 0.01), regardless of the heparinization protocolor the type of cannulation. Conclusions: Given the local venous complications and DVT after electrophysiological procedures, heparinization is not necessary for right-sided electrophysiological procedures. In situ thrombosis is a minor complication that can be reduced by heparinization in patients undergoing one-line cannulation and in women during longer procedures. (Cardiol J 2012; 19, 1: 15–19

Effects of cross-linking modification with phosphoryl chloride (POCl3) on pysiochemical properties of barley starch

Chemical methods are one of the comon method in starch modification. This study aimed at investigating of cross-link affection of phosphoryl chloride with two different levels 0.5 and 1g.kg-1 in order to enhance funciotnal proeprties and physiochemical changes on extracted starch from barley variety Bahman which cultivates in Chahr-Mahal Bakhtiari Province of Iran. Obtained results indicated that cross-linking leads to reduce sweeling power of strach granuls compred to natural starch and the amount of reduciton increase via the substitituin level. Powerfull cross-linkingnetween starch chains casue more resistance of granules to seweeling which is increased by means of cross-linking dgree. Additioally,  investigationresults from synersis revealed that releasing water percentage in cross-linked starches increase in comparison to natural starches and this amount depends onthe amount of cross-link surface with a significantly difference in (α <0.05). Gelatinization temperature in both levels negligibly increased by modification where in low level of cross-linking was more. Furthermoe evaluating gelation temperatures of both natural and cross-linked modified starches showed that addition of phosphate groups in starch and creating extra coovalent bonds make granues more compressed reulting in slight increase of To, Tp, Tcin barley starch. Icreasing of temperature observed more in less concentration of cross-links. Evaluation of viscosity changes also revealed that this modification depending on increasing the amount of Phosphoryl Chloride led to increasing peak temperature, diminish peak and setback viscosity. Result also exhibited that in morphological level, cross-link causes to incidence changes in particles' diameter size. The comparison of diameter average and frequency between natural starch and cross-links starch exhibited that in cross-linkd treatment with 0.5% phosphoryl chloride, increase in frequency of granules with diameter of 6 - 10µm and >20 µm obersced. While frequency of granules with diamater size of 2 - 6 µm and 10 - 20 µm has been reduced to 0 which create bigger granules

مروری بر بازاریابی عصبی و کاربرد آن در ورزش (بررسی مطالعات تجربی)

Successful sports marketing begins with understanding why and how consumers behave. To be successful in sports marketing, we need to incorporate the impact of important psychological variables into our research and decisions so that we can properly analyze consumer behavior. The behavior of a sports consumer in the face of a product or service depends entirely on her/his mind. Neuromarketing can detect conscious and unconscious reactions in people's minds. Traditional marketing, unlike neural research, does not have the ability to detect these emotions. In neural methods, unlike the traditional method, the unconscious causes of buying and the effect that advertising has on people's minds over time are discovered. This article has been done based on reviewing studies in the field of neural marketing in order to increase awareness and knowledge of this field in sports. Based on previous studies, it can be said that neural sports marketing from an empirical perspective is done in four groups: consumer decision making and the formation of consumer preferences, brain reward system interaction with marketing, consumer motivational and emotional responses, and neural foundations of memory. This emerging discipline connects neuroscience to sports consumer behavior, which, despite its perceived benefits, is still in its infancy in sports research. Now the future of neural marketing science is in a new field. Therefore, this study presents new concepts and research proposals in the field of sports.بازاریابی ورزشی موفق با درک چرایی و چگونگی رفتار مصرف‌کننده آغاز می‌شود. برای موفقیت در بازاریابی ورزشی، باید تاثیر متغيرهاي مهم روانشناسی را در تحقیقات و تصمیمات خود جای دهیم تا بتوانیم رفتار مصرف‌کنندگان را به درستی تحلیل کنیم. رفتار یک مصرف‌کننده ورزشی در مواجهه با کالا یا خدمت، کاملاً بستگی به ذهن او دارد. نورومارکتینگ، می‌تواند واکنش‌های خودآگاه و ناخودآگاه ذهن افراد را کشف کند. بازاریابی سنتی برخلاف تحقیقات عصبی توانایی کشف این احساسات را ندارد. برخلاف روش سنتی در روش‌های عصبی، علل ناخودآگاه خرید و تأثیری که تبلیغات در گذر زمان ‌بر ذهن افراد می‌گذارد کشف می‌شود. این مقاله در جهت افزایش آگاهی و شناخت بیشتر این حیطه در حوزه ورزش بر اساس مرور مطالعات حوزه بازاریابی عصبی صورت گرفته است. بر اساس بررسی‌های صورت گرفته بر روی مطالعات پیشین می‌توان گفت که بازاریابی عصبی ورزشی از دیدگاه تجربی در چهار گروه تصمیم‌گیری مصرف‌کننده و شکل‌گیری ترجیحات مصرف‌کنندگان، تعامل سیستم پاداش مغز با بازاریابی، پاسخ‌های انگیزشی و عاطفی مصرف‌کنندگان و مبانی عصبی حافظه انجام می‌پذیرد. این رشته‌ی نوظهور و تازه، علوم اعصاب را به رفتار مصرف‌کننده ورزشی متصل می‌کند که علیرغم سودمندی‌های متصور، در تحقیقات ورزشی هنوز در مراحل ابتدايي به سر می‌برد. هم‌اکنون آینده علم بازاریابی عصبی در میدان جدیدی قرار دارد به همین منظور این مطالعه با ارائه مفاهیم کاربردی و پیشنهادات پژوهشی جدید حوزه ورزش را مطرح می‌کند

Renal Amyloidosis Due to Juvenile Rheumatoid Arthritis Occurring in Early Childhood

Renal amyloidosis is a late manifestation of chronic juvenile rheumatoid arthritis (JRA) and usually manifests during the first 10 to 15 years after the onset of JRA. We hereby report a boy with JRA-related renal amyloidosis who presented with nephrotic syndrome in early childhood. Amyloidosis was associated with a 6-year history of juvenile rheumatic arthritis (JRA). Diagnosis of renal amyloidosis was confirmed by the deposition of Congo red positive amyloid fibrils within the glomeruli. Polarized light microscopy showed the classic green birefringence appearance.Key words: Arthritis, Juvenile; Amyloidosis, familial renal; Chil

Dangling-bond charge qubit on a silicon surface

Two closely spaced dangling bonds positioned on a silicon surface and sharing an excess electron are revealed to be a strong candidate for a charge qubit. Based on our study of the coherent dynamics of this qubit, its extremely high tunneling rate ~ 10^14 1/s greatly exceeds the expected decoherence rates for a silicon-based system, thereby overcoming a critical obstacle of charge qubit quantum computing. We investigate possible configurations of dangling bond qubits for quantum computing devices. A first-order analysis of coherent dynamics of dangling bonds shows promise in this respect.Comment: 17 pages, 3 EPS figures, 1 tabl
