RoBA Multiplier: A Rounding-Based Approximate Multiplier for High-Speed yet Energy-Efficient Digital Signal Processing

—In this paper, we propose an approximate multiplier that is high speed yet energy efficient. Now-a-days, Energy minimization is one of the main design requirements especially in the portable gadgets i.e., smart phones, tablets and so on. In these types of gadgets, DSP blocks are key components, where the computational core of these blocks is the arithmetic logic unit where multiplications have a greatest share. So, by the use of the multipliers the computational part of multiplications is omitted by improving the speed and power/efficiency characteristics of multipliers as it plays a key role. In this, the approach is to round the operands to nearest exponent of two. By this approximations are made for improving the speed and efficiency. Since the final outputs are used in two Image processing applications, i.e., image sharpening and smoothing. This can be performed at different design abstraction levels i.e., circuit, logic and architecture levels using different techniques, here we use function approximation method (e.g., modifying the Boolean function of a circuit), a number of approximating arithmetic building blocks, such as adders, multipliers have been suggested. Finally, It has added advantage that it can be used as common multiplier design for both signed and un-signed operations and reduces logic size and facilitates with less power and delay. Here we are using Verilog HDL and Xilinx ISE14.8 software tools for simulation and synthesis purpose.
Smelowskia sunhangii (Brassicaceae), a new species from China, with a re-evaluation of the S. tibetica complex

Abstract Smelowskia sunhangii, from Qinghai and Tibet (China), is described and illustrated. Morphological and molecular data indicate that S. sunhangii is closely related to Smelowskia tibetica, from which it is easily distinguished by the densely hirsute (vs. glabrous or sparsely pubescent), elliptic to ovate-lanceolate (vs. suborbicular, oblong, or lanceolate) fruits with undulate (vs. straight) margins. A re-evaluation of the widely distributed S. tibetica and related taxa is also provided.

Oncolytic Viruses as Nanomedicines against the Tumor Microenvironment

The tumor microenvironment is best described as the battleground for fighting cancer and the host immune system. Contrary to primitive beliefs that cancer growth and progression are solely dependent on cancer cells, recent studies suggest that the cancer cell mass environs also play a pivotal role. Active crosstalk between the tumor cells and their surrounding microenvironment permits their collusion to effectuate high cancer cell proliferation and metastasis. Tumors have been reported to actively recruit and alter immune cells' phenotypes and functions to either promote immune suppression or increase the tolerance towards tumor-associated antigens. Comprehending the part played by the tumor microenvironment in tumor progression and its mechanism of action paves the way for developing novel therapeutic approaches for a more personalized and efficient tumor microenvironment targeted anticancer treatment. This review elaborates on the nature and importance of the tumor microenvironment and the anti-cancer therapeutic strategies designed to target them. Furthermore, we discuss in-depth the employment of oncolytic viruses as nanomedicines for tumor microenvironment targeted anticancer therapy. This review also delineates the benefits of combining novel therapeutic approaches to existing treatment strategies to improve disease prognosis.

Super Absorbent Silk Fibroin Hydrogel

Super absorbent polymers have a wide range of applications in the fields of biomaterials, agriculture, physiological products of daily-uses, and others. Silk fibroin, as a natural biomaterial with excellent biocompatibility, is showing a good prospect of applications in the field of biomedicine. In this work, silk protein fibroin is used as the carrier, riboflavin as the photosensitizer, and accordingly hydrogel is prepared by free radical cross-linking under ultraviolet light. The fibroin in the hydrogel contains mainly the random coil structure, and the covalent bond cross-linking hinders the crystallization of the silk fibroin, thereby an amorphous silk fibroin hydrogel is obtained. This hydrogel has a capacity to absorb water 90 times more than its own mass, a fast water absorption speed, and absorbs a good amount of water within a minute. This fabricated silk protein fibroin hydrogel having a quick water-absorbing ability; therefore, this can be used for rapid hemostasis of wounds and for absorbing other body exudates.
Teaching Beginning Chemistry Students Simple Lewis Dot Structures

Students beginning their initial study of chemistry often have a difficult time mastering simple Lewis dot structures. Textbooks show students how to manipulate Lewis structures by moving valence electron dots around the chemical structure so each atom has an octet or duet. However, an easier method of teaching Lewis structures for simple molecules, based on the octet rule (the fundamental concept of Lewis structures), enables most students to master drawing Lewis structures in one class session.

Efficiency of Option Market as an Exchange Rate Risk Hedging Instrument

Since 1999, Colombia adopted an exchange rate regime in which the United States dollars/Colombian pesos (USD/COP) exchange rate is floating. This means that quoted prices in the market of this currency depend on the existing supply and demand. In some instances, Banco de la República intervenes in the purchase or sale of currencies (dollar) in order to regulate the prices slightly. This paper presents the empirical validation of the options as hedging instruments, some inefficiencies of this financial instrument were found due to their low availability and high transaction costs in the use of this asset as an exchange risk hedging instrument. The goal of this study was validate the USD/COP options assets as hedging instruments of exchange risk, that has not yet studied on Colombian companies, who carry out foreign currency transactions; The present study argues the importance for the companies to use a hedging strategy to diversify the exchange rate risk; consequently, companies who perform currency operations (with dollars in this case) must include operations to manage financial risks in the USD/COP exchange rate through financial instruments, such as the exchange rate options contracts, to reduce transaction costs. For this, the spot prices and USD/COP options between 2011 and 2018, found in the Colombian stock exchange, were analyzed by valuing its risk through the VaR (value at risk), evaluating its impacts as a risk-hedging instrument in the exchange rate, and comparing hedging effects through a Sharpe ratio model (Alaganar & Bhar, 2007; de Bruin & Walter, 2017; Jorion, 2007).

Building information modeling and artificial intelligence: Advanced technologies for the digitalisation of seismic damage in existing buildings

This research, which is based on the digital technologies building information modeling (BIM) and artificial intelligence, describes achievements in the field of detecting, assessing, and digitalising damage in existing buildings. The purpose of the study is to highlight the potential and current benefits of combining structural‐assessment methods with the automatic digitisation of hazard‐induced damage in affected buildings. To this end, the aforementioned technologies are employed in the form of an image‐based recognition‐BIM classification technique applied to on‐site visual‐damage data. By extending the methodology to existing masonry and concrete buildings, the results obtained open up new opportunities for speeding up the process of assessing, designing, and managing seismic repair/retrofit interventions using image data acquired in the manner described.
Current Multiplier Based Synapse and Neuron Circuits for Compact SNN Chip

Spiking Neural Networks having biological plausible architecture are considered to be more suitable for energy efficient hardware implementation. When it comes to realize the hardware implementation of a large-scale Neural network for mobile applications, area and power consumption constraints become more critical. Optimizing Spiking neural network, constituting of neuron and synapse circuits, for area and power is essential. In this paper we present a more optimized version of Synapse and neuron circuits. We propose an analog CMOS implementation of a current multiplier charge injector-based Synapse and neuron circuit. The synapse circuit modulates the input spike rates by a trained weight value and injects an equivalent current. The neuron circuit integrates the injected synaptic current and evokes an output digital spike event. The circuit implementation is done using 65nm process design kit. The proposed circuit implementation exhibits all the temporal characteristics of Spiking neural networks. The circuit implementation has been optimized for area and power consumption and therefore can be easily constituted into a large-scale spiking neural network. Furthermore, the compact circuit implementation can benefit from the high resolution with very less increase in area and power.
VANET: Framework, Challenges and Applications

Vehicular Ad-Hoc Network (VANET) is one of the essential research field because of large increase in usage of vehicles on road. Many VANET applications are employed to improve road safety conditions, vehicle traffic, an emergency warning to vehicle drivers, collision avoidance and other non-safety applications for comfort. The main aim of these applications are to modernize the various processes associated with road traffic, vehicles, drivers, passengers and pedestrians by implementing smart transport systems. This study is to implement an intelligent vehicular transport design to improve the road safety, navigation and comfort. VANET communication technology is a combination of mobile vehicles with ad hoc networks. The purpose of this research is to predict and prevent road accidents by transmitting emergency messages using vehicular network technology. While transmitting emergency messages, the VANET has various challenges. They are High mobility of the vehicles, Dynamic topology, Wireless communication, Minimum transmission delay, Connectivity of the network, optimal usage of transmission power. These challenges leave the vehicular networking disconnected and make an exchange of information very difficult. Even though many researchers have done significant work during the last decade on vehicular networking, some problems have not yet been solved.
Contrasting effects of secondary organic aerosol formations on organic aerosol 
hygroscopicity

Abstract. Water uptake abilities of organic aerosol under sub-saturated conditions play critical roles in direct aerosol radiative effects and atmospheric chemistry, however, field characterizations of organic aerosol hygroscopicity parameter κOA under sub-saturated conditions remain limited. In this study, a field campaign was conducted to characterize κOA at relative humidity of 80 % with hourly time resolution for the first time in the Pearl River Delta region of China. Observation results show that during this campaign secondary organic aerosol (SOA) dominated total organic aerosol mass (mass fraction >70 % on average), which provides us a unique opportunity to investigate influences of SOA formation on κOA. Results demonstrate that the commonly used organic aerosol oxidation level parameter O / C was weakly correlated with κOA and failed in describing the variations of κOA. However, the variations in κOA were well reproduced by mass fractions of organic aerosol factor resolved based on aerosol mass spectrometer measurements. The more oxygenated organic aerosol (MOOA) factor, exhibiting the highest average O / C (~1) among all organic aerosol factors, was the most important factor driving the increase of κOA and was commonly associated with regional air masses. The less oxygenated organic aerosol (LOOA, average O / C of 0.72) factor, revealed strong daytime production, exerting negative effects on κOA. Surprisingly, the aged biomass burning organic aerosol (aBBOA) factor also formed quickly during daytime and shared a similar diurnal pattern with LOOA, but had much lower O / C (0.39) and had positive effects on κOA. The correlation coefficient between κOA and mass fractions of aBBOA and MOOA in total organic aerosol mass reached above 0.8. The contrasting effects of LOOA and aBBOA formation on κOA demonstrates that volatile organic compound (VOC) precursors from diverse sources and different SOA formation processes may result in SOA with different chemical composition, functional properties as well as microphysical structure, consequently, exert distinct influences on κOA and render single oxidation level parameters (such as O / C) unable to capture those differences. Aside from that, distinct effects of aBBOA on κOA was observed during different episodes, suggesting that the hygroscopicity of SOA associated with similar sources might also differ much under different emission and atmospheric conditions. Overall, these results highlight that it is imperative to conduct more researches on κOA characterization under different meteorological and source conditions, and examine its relationship with VOC precursor profiles and formation pathways to formulate a better characterization and develop more appropriate parameterization approaches in chemical and climate models.

Impedance spectroscopy study of nanopore arrays for biosensing applications

Molecular or ion transport through a single nanopore or nanopore array is a key process in a number of applications including: molecular separation, biosensing, energy storage, nanofluidics and nanoelectronics. In this study, the electrochemical and electrical properties of nanopore arrays were investigated by electrochemical impedance spectroscopy (EIS), to explore their capability towards the development of improved nanopore biosensing devices. Anodic aluminum oxide (AAO) nanopore arrays with square patterns were fabricated by a photolithographic technique for use as a biosensing platform. To demonstrate the potential capability of these nanoporous arrays for biosensing applications, their internal surfaces were functionalized with a self-assembled monolayer of phosphonic acid; followed by covalent bonding with the model binding molecule streptavidin. The sensing performance of the prepared sensing device was characterized by EIS using different concentrations of biotin as probe molecule. The changes in impedance signal in response to the specific binding of biotin molecules to the streptavidin inside nanopores were monitored and explored depending on pore morphology. The results obtained for this system exhibit a high level of sensitivity and selectivity, which could provide the basis for the development of superior biosensing devices.
Innovative Differential Magnetic Localization Method for Capsule Endoscopy to Prevent Interference Caused by the Geomagnetic Field

Wireless capsule endoscopy is an established medical application for the examination of the gastrointestinal tract. However, the robust and precise localization of these capsules is still in need of further scientific investigation. This paper presents an innovative differential magnetic localization method for capsule endoscopy to prevent interference caused by the geomagnetic field. The effect of changing the orientation of the capsule on the localization process was also examined. Simulations using COMSOL Multiphysics with the superimposed geomagnetic field were performed. The Levenberg–Marquardt algorithm was applied in MATLAB to estimate the position and orientation of the capsule. Comparing the proposed differential method with the absolute magnetic localization method under ideal conditions, the mean position and orientation errors were reduced by three orders in magnitude to less than 0.1 mm and 0.1 ° respectively. Even if sensor non-idealities are considered, the simulationbased results reveal that our proposed method is competitive with state-of-the-art geomagnetic compensation methods for static magnetic localization of capsule endoscopes.The achieved localization accuracy by applying the differential method is not dependent on the rotation of the localization system relative to the geomagnetic flux density under the made assumptions and the impact of the magnet orientation is neglectable. It is concluded that the proposed method is capable of preventing all interference whose components are approximately equal at all sensors with identical orientation.
