Abstract

A sacrificial film of polystyrene nanoparticles was utilized to introduce nano-cavities in mesoporous metal oxide layers. This enabled the growth of larger perovskite crystals inside the oxide scaffold with significantly suppressed non-radiative recombination and improving device performance. This work exemplifies potential applications of such nanoarchitectonic approaches in perovskite opto-electronic devices., Comment: 4 pages

Abstract

Spintronic devices are considered as promising candidates in implementing neuromorphic systems or hardware neural networks, which are expected to perform better than other existing computing systems for certain data classification and regression tasks. In this paper, we have designed a feedforward Fully Connected Neural Network (FCNN) with no hidden layer using spin orbit torque driven domain wall devices as synapses and transistor based analog circuits as neurons. A feedback circuit is also designed using transistors, which at every iteration computes the change in weights of the synapses needed to train the network using Stochastic Gradient Descent (SGD) method. Subsequently it sends write current pulses to the domain wall based synaptic devices which move the domain walls and updates the weights of the synapses. Through a combination of micromagnetic simulations, analog circuit simulations and numerically solving FCNN training equations, we demonstrate "on-chip" training of the designed FCNN on the MNIST database of handwritten digits in this paper. We report the training and test accuracies, energy consumed in the synaptic devices for the training and possible issues with hardware implementation of FCNN that can limit its test accuracy., Comment: Submitted on November 5, 2018 for review in journal

Abstract

This study investigates the use of planar wingtip attachments to improve the lift generating performance of low aspect ratio (AR) flat-plate wings in the low Reynolds number (Re) range (<105). Inspired by nature's solutions, the slotted wingtip feathers of high lift wings as seen in eagles, we tested different configurations of wingtip attachments, ranging from a base plate with no attachments to plates with one, two, or four attachments for Re=8×104−15×104. The lift-to-drag (L/D) ratio, a commonly used metric for gauging the aerodynamic performance, shows that the configuration with four attachments (4A) has the superior performance. In the case of ARs of 1.0 and 1.5, the 4A configuration returns an average improvement of 20% and 7% over the base plate, respectively. The Oswald's efficiency factor (e), calculated for the experimental cases, is varied from a low 0.24 to more typical values of 0.86. The force per unit volume parameter is used to compare the performances of the modified wings and to take into account the weight added by the attachments. The results obtained demonstrate that the 4A configuration offers superior performance compared to the weight gained because of the addition of the attachments. [ABSTRACT FROM AUTHOR]

Author

Depaa, R. A. B., Ibrahim, Haruna, Verma, Anand, Singh, Vinay Kumar, Mishra, Abhishek, and Yadav, Abhay

Abstract

The depletion of natural resource, the generation of enormous quantities of waste, and the subsequent disposal of that waste are driving modem society to adopt more environmentally friendly construction methods now than ever before. It has been utilised in construction for decades because of its ability to prevent structural concrete cracks while also enhancing the flexibility of concrete. Environmental and resource-saving concerns have prompted extensive research into developing more sustainable, resource-saving, and recycled alternatives to industrial steel fibres. The goal is to replace commercially available, expensive steel fibres with recycled steel fibres. There are significant differences between recycled steel fibre reinforced cement mixtures and conventional steel fibre reinforced cement mixtures in both the fresh and hardened phases. For anyone interested in learning more about recycled steel fibres and how they might be used in a variety of cement-based composites, this website provides a brief explanation. The effect of RSFs on fresh-state property of concretes, such as porosity, workability, volumetric stability, and bulk density, has been a source of debate. Compressive strength, hardness, tensile strength, durability, and impact resistances are only a few of the mechanical qualities evaluated on this page. Some mechanical characteristics include Research gaps in the field of recycled steels fibre reinforced cementitious system in different application will be identified through this study, which aims to undertake a comprehensive examination of the available literature.

Author

Savandaiah, Rudresha, Selvaraju, Sivamani, Verma, Anand, Effendy, Femmy, Dixit, Chandra Kumar, and Gori, Yatrika

Abstract

Numerous significant advancements with the use of sophisticated elements for compact buildings in recent decades. Capsules, polyurethane foam, and, finally, nanoparticles are all instances of short and the long materials. The biomechanics of Hybrid may be applied to the study of structures composed of these elements. But, new uses, production methods, chemical ratios, and other factors have prompted a reconsideration of nanocomposite kinematics. A few of the current trends are explained in this work, such as advances in the implementation of long- and short-fiber-reinforced nanocomposite, fiberboard impacted by multi field loadings, efficacious property-based assessment of polyurethane foam, and the explanation of nanostructured materials using Governing Equations notions. Technology is the beginning point for the review. [ABSTRACT FROM AUTHOR]

Author

Dhali, Tapan K, Khanna, Urmi, D'Souza, Paschal, and Verma, Anand K

Abstract

Angioplasmocellular hyperplasia is a rare clinical condition with blood vessel proliferation and a reactive plasma cell infiltrate. To the best of our knowledge fewer than 20 cases of cutaneous angioplasmocellular hyperplasia have been published in English literature. We report a case of a 65-year-old man who presented with a long standing asymptomatic flesh colored ulcerated nodule on the back. Histopathological examination revealed a dermal vascular proliferation with polyclonal plasma cell infiltration. A diagnosis of angioplasmocellular hyperplasia was established. This entity is rare and we would like to emphasize the importance of clinico-pathological correlation to differentiate it from various other conditions of cutaneous plasma cell infiltration.

Abstract

Background and Aims: The pectoral nerve block types I and II are novel techniques to provide analgesia for modified radical mastectomy (MRM) surgeries performed under general anesthesia. The primary objective of this study was to compare the duration of effective analgesia, and the secondary objectives were to evaluate the total amount of rescue analgesics in 24 h, hemodynamic changes, and postoperative adverse effects. Methods: This prospective, randomized, double-blind study was conducted on a total of 80 women with breast cancer belonging to American Society of Anesthesiologist class I and II scheduled for MRM, which were randomly allocated into two groups - Group R (n = 40) received 0.25% ropivacaine 29 ml + NS 1 ml and Group RD (n = 40) received 0.25% ropivacaine 29 ml + dexamethasone (4 mg) 1 ml. Ten milliliters of the study drug was used in Pecs I and the rest 20 ml in Pecs II block posttumor resection. Results: The duration of analgesia was statistically significantly longer in RD (778.75 ± 55.12 min) compared to Group R (412.63 ± 21.69 min) (P < 0.05). Pain scores were significantly less in Group RD. The mean dose of acetaminophen required was significantly less in Group RD (2362.50 ± 375.32 mg) than in Group R (3525.00 ± 298.50 mg) (P < 0.05). The incidence of adverse events was similar in both groups. Conclusion: The addition of dexamethasone with ropivacaine in the Pecs block can be used for prolonging the effective duration of analgesia and decreasing postoperative analgesic consumption with comparable hemodynamic and side effect profiles.

Abstract

Background and Aims: Modified electroconvulsive therapy is routinely used to treat complicated psychiatric disorders. Its therapeutic effect is directly proportional to induced seizure duration but it is associated with hemodynamic disturbances. The aim of this study was to evaluate the effect of a ketamine + propofol combination ("ketofol") for electroconvulsive therapy and to compare these with the effects of propofol alone. Methods: In this prospective study, 60 patients aged 18-60 years with American Society of Anesthesiologists (ASA) I and II for psychiatric disorders were included. Patients were divided into two groups (30 each). Group P received propofol at 10 mg/ml and group K received ketofo at 10 mg/ml (ketamine 5 mg/ml and propofol 5 mg/ml in a 1:1 ratio). Motor/electroencephalography (EEG) seizure duration, induction time, hemodynamic variables, recovery time, agitation score, and complications were recorded. Standard qualitative and quantitative tests were used to compare the data (e.g., unpaired student t-test, Chi-squared test, etc). A P value of < 0.05 was considered to be significant. Results: The mean duration of (motor/EEG) seizure was statistically significantly high in the ketofol group compared to the propofol group (P = 0.0001/0.0001). The mean induction time was significantly less in the ketofol group compared to propofol group (P = 0.0001). The recovery time was significantly early in group K patients compared to group P (P = 0.004). The ketofol group was more hemodynamically stable with comparable agitation score and side effects than patients in the propofol group. Conclusion: In modified ECT, ketofol was associated with longer seizure duration, lesser induction time, better hemodynamic stability, early recovery with comparable post ECT agitation and adverse effects compared to propofol alone.
