Single crystals of hydrogen bonded 4-methoxyanilinium perchlorate (4MAPC) have been grown and the corresponding structure has been confirmed by Single crystal XRD analysis. The charge transfer on the nitrogen site of 4-methoxyaniline has been confirmed from elongated carbon and nitrogen bond distances. The Quantum chemical calculations of 4-methoxyanilinium perchlorate have been studied at HF and DFT methods with 6-311++G(d,p) level of theory to get the optimized geometry, FT-IR/FT-Raman spectra, charge distributions and the microscopic NLO efficiency of the title compound. The HOMO-LUMO analysis indicates that the electron delocalization and the energy gap between the HOMO-LUMO of the 4MAPC indicates the charge transfer within the molecule. The energy gap values between the molecular orbitals are 4.7358 eV (DFT)/6.8044(HF) eV, which makes the compound more reactive. The Population analysis has been studied and discussed. The Hirshfeld surface analysis suggests that the most significant contribution to the crystal packing is by O…H contacts (29%). The microscopic NLO parameters of 4MAPC have been calculated and the relative second order hyperpolarizability (γ) of the compound has found to be 47 times greater than that of standard Urea. .

Pelizaeus-Merzbacher Disease (PMD) is a rare genetic disorder affecting brain and spinal cord. We report a 11-year-old child with PMD with multiple caries for teeth extraction under general anaesthesia. Prolonged neuromuscular blockade is of major concern in these patients and hence the importance of appropriate neuromuscular blockade management during procedure.

Operation at millimeter-wave/sub-terahertz frequencies allows one to realize very high data-rate transceivers for wireless chip-to-chip communication. In this paper, a 240 GHz 16 Gbps QPSK receiver is demonstrated in 65 nm CMOS technology. The receiver employs a direct-conversion mixer-first architecture with an integrated slotted loop antenna. A 240 GHz LO chain drives the passive mixers to down-convert the modulated data to baseband. The baseband signal is then amplified using high gain, wide bandwidth amplifiers. The receiver has a noise figure of 15 dB with a conversion gain of 25 dB calculated from measurement data. The receiver achieves a data rate of 10 Gbps (with ${\rm BER} ) and a maximum data rate of 16 Gbps (with BER of $10^{-4}$ ) with a receiver efficiency of 16 pJ/bit.

In this paper, a 240 GHz 16 Gbps QPSK transmitter is demonstrated in 65 nm bulk CMOS process. The transmitter chain employs an 80 GHz local oscillator and a modulator to generate the data that is amplified by a class-E switching power amplifier. The amplified signal then drives the 240 GHz tripler to generate the required modulated data. By using on-chip slotted loop antennas, the transmitter achieves an EIRP of 1 dBm. A maximum data rate of 16 Gbps is achieved with a transmitter efficiency of 14 pJ/bit.

Although sub-capital neck fracture of femur over an old healed trochanter fracture with dynamic hip screw implant in situ is not uncommon, but can be an unexpected outcome for both surgeon and patient. Many series of case reports have been published so far in the literature, but the majority of them were in relatively old and female age groups with poor bone stock. Herewith, we are presenting an unusual occurrence of this type of entity in a 58-year healthy Indian male, which is managed with hemiarthroplasty by the modular bipolar prosthesis.

CMOS technology scaling has enabled the design of high speed and efficient digital circuits. However, the continued scaling is detrimental to the design of RF and mm-wave systems. Higher sensitivity to process variations and inaccuracies in modeling of active and passive devices pose another challenge to the design of these systems at deep submicron technology nodes. This paper describes the design of a 60 GHz power amplifier in 28 nm CMOS technology. A drain-source neutralization technique maintains the stability of the PA and the wideband nature is achieved by the application of low-k transformer networks. The PA comprises of three stages and achieves an overall bandwidth of 11 GHz with a peak gain of 24.4 dB. Using a two-way transmission line based power combiner, the PA delivers a saturated output power of 16.5 dBm with a peak power added efficiency (PAE) of 12.6%.

In recent years, it has become increasingly important to determine the age of living people for a variety of reasons, including identifying criminal and legal responsibility and for many other social events such as birth certificate, marriage, beginning a job, joining the army and retirement Objectives: The aim of this study was to assess the developmental stages of mandibular third molar for estimation of dental age (DA) in different age groups and to evaluate the possible correlation between DA and chronological age (CA) in South Indian population. Materials and Methods: Digital orthopantomography of 330 subjects (165 males, 165 females) who fit the study and the criteria were obtained. Assessment of mandibular third molar development was performed using Demirjian et al., modified method and DA was assessed using tooth specific stages. Results and Discussion: The present study showed a significant correlation between DA and CA in both males and females. Third molar development commenced around 9 years and root completion takes place around 18.9 years in males and in females 9 years and 18.6 years respectively. Demirjian modified method underestimated the mean age of males by 0.8 years and females by 0.5 years and also showed that females mature earlier than males in selected population. Conclusion: Digital radiographic assessment of mandibular third molar development can be used to generate mean DA using Demirjian modified method and also the estimated age range for an individual of unknown CA. Since the Demirjian method is based on French-Canadian population, to enhance the accuracy of forensic age estimates based on third molar development, the use of population-specific standards is recommended.

Wireless transmitters employing switching power amplifiers are popular both in RF and mm-wave designs. The efficiency of switching power amplifiers is dictated mainly by the maximum achievable switch size which in turn is governed by the switch transition frequency (tradeoff between switch on-resistance and capacitance). This paper presents a new architecture, the distributed switching power amplifier (DSPA), that helps break this tradeoff by distributing the switch in the nonlinear amplifier design, especially at high frequencies. A comprehensive analytical framework has been developed and the theory has been compared with simulation results.

g r a p h i c a l a b s t r a c t a b s t r a c t An extensive experimental evaluation of electrical conductivity of nanofluids containing metallic and ceramic particles (Cu, Al2O3, and CuO) with different volume fractions in the dilute regime, particle sizes, electrolyte effect, temperature and base fluids has been carried out. It is observed that, in both water- and ethylene glycol (EG)-based nanofluids, the electrical conductivity increases with increasing particle concentration and reducing particle size. It is argued that the effective dielectric constant and density are at the root of the counterintuitive observation that the electrical conductivity enhancement of ceramic nanofluids is more than that of metal-based ones which is substantiated by the Clausius-Mossotti rela- tion for the polar fluids. The influence of surfactant is found to increase the stability and decrease the electrical conductivity of the nanofluids by increasing its viscosity. There is a rise in electrical conduc- tivity of nanofluids having low electrolyte concentration whereas a decrement is observed in nanofluids of high electrolyte concentration due to reduced surface conductance. These experimental observations on alumina nanofluids are compared with the theoretical model proposed by O'Brien (19) for electrical conductivity of dilute suspensions. It has also been observed that there is no significant effect of fluid temperature on the electrical conductivity in the range 30-60 ◦C. This clearly indicates that enhance- ment mechanism for electrical conductivity is completely different from that of thermal conductivity in nanofluids.

The paper presents cooperative communication based wireless sensor network for monitoring Green house related parameters such as Temperature, humidity and Carbon-di-oxide. The system is demonstrated by using network simulator NS2 with increased network capacity to suit large geo graphical areas. The comparison results show that cooperative transmission provides better performance than non-cooperative transmission in various aspects, such as packet loss, packet delivery ratio (PDR), network capacity and throughput. It is observed that the energy efficient and successful transmission occurred within transmission range and better link quality. Further, the results proved that the transmission range increases as when throughput and packet delivery ratio are decreasing.

Network coding technique based wireless sensor network for environmental monitoring is described here. The network coding is implemented in CC2530 microcontroller and the performance of wireless sensor network is evaluated by analyzing packet delivery ratio (PDR) and packet error rate (PER). It is observed that the resources can be shared among the nodes with minimum number of transmission and repetition of packets can be reduced by using Network Coding.

The paper presents an indoor air quality monitoring system which comprises of real-time sensing unit that enables remote monitoring of environmental carbon-di-oxide, temperature, and relative humidity. The simple mail transfer protocol (SMTP)-based remote monitoring system employs an Internet of Things (IoT) signal processor (CC3100) interfaced on top of a low-power microcontroller (MSP430F5529). The system is also packed with a short messaging service (SMS)-based emergency alerting mechanism on the mobile network through SIM900 GSM module. The whole system when integrated with pre-calibrated non-dispersive infrared (COZIR) sensing unit showed good response in communicating the alert messages and E-mail. The information from sensing unit can be analyzed and logged for any period of time.

The viscosity of Graphene nano-sheet suspensions (GNS)and its behavior with temperature and concentration have been experimentally determined. A physical mechanism for the enhanced viscosity over the base fluids has been proposed for the poly-dispersed GNSs. Experimental data reveals that enhancement of viscosity for GNSs lie in between that of Carbon Nanotube Suspensions (CNTSs) and nano Alumina suspensions (nAS) , indicating the hybrid mechanism of percolation (like CNTs) and Brownian motion assisted sheet dynamics (like Alumina particles). Sheet dynamics and percolation, along with a proposed percolation Network Dynamicity Factor; have been used to determine a dimensionally consistent analytical model to accurately determine and explain the viscosity of poly-dispersed GNSs. It has been hypothesized that the dynamic sheets behave qualitatively analogous to gas molecules. The model also provides insight into the mechanisms of viscous behavior of different dilute nanoparticle suspensions. The model has been found to be in agreement with the GNS experimental data, and even for CNT and nano Alumina suspensions.

A real-time cooperative communication based wireless network is presented for monitoring health and activity of an end-user in their environment. The cooperative communication offers better energy consumption and also an opportunity to aware the current location of a user non-intrusively. The link between mobile sensor node and relay node is dynamically established by using Received Signal Strength Indicator (RSSI) and Link Quality Indicator (LQI) based on adaptive relay selection scheme. The study proposes a Linear Acceleration based Transmission Power Decision Control (LA-TPDC) algorithm to further enhance the energy efficiency of cooperative communication. Further, the occurrences of false alarms are carefully prevented by introducing three stages of sequential warning system. The real-time experiments are carried-out by using the nodes, namely mobile sensor node, relay nodes and a destination node which are indigenously developed by using a CC430 microcontroller integrated with an in-built transceiver at 868 MHz. The wireless node performance characteristics, such as energy consumption, Signal-Noise ratio (SNR), Bit Error Rate (BER), Packet Delivery Ratio (PDR) and transmission offset are evaluated for all the participated nodes. The experimental results observed that the proposed linear acceleration based transmission power decision control algorithm almost doubles the battery life time than energy efficient conventional cooperative communication.

This paper describes a wireless sensor network-based indoor air quality monitoring system. The indoor air quality defines the quality of the environment where people live. Here wireless sensor network serves as the tool for estimating the indoor air quality. The WSN comprises sensor nodes and a coordinator node which communicates using the IEEE 802.15.4 wireless standard ZigBee wireless module. The indoor air quality estimation is done by interfacing CO2, temperature and RH (Relative humidity) sensors with the sensor node. The sensor node gathers the sensor data and reports it to the coordinator for real-time monitoring using a GUI (Graphical user interface) developed in Java NetBeans to run on windows PC. The collected data can be used to maintain the environment parameters by interfacing it to a HVAC (Heating, Ventilation and Air Conditioning) system.

The next generation of technology is connecting to internet from a standalone device. The background of Internet of Things (IoT), which covers various areas like ubiquitous positioning, biometrics, energy harvesting technologies, and machine vision, makes researches to make deep study in these individual technologies. The paper presents human vital sign monitoring system which includes measurement of pulse rate and body temperature of patients from remote locations. Standalone device connectivity with Simple Mail Transfer Protocol (SMTP) server can be achieved by implementing a TCP/IP stack and Ethernet interface in a MSP430 controller. An IoT enabled network processor CC3100 and Computational processor MSP430 is interfaced with sensory components and made to communicate emergency signals through Global System for Mobile (GSM) and SMTP server. The sensors are pre-calibrated and the wireless system showed good response in sending messages and email. The physiological signals can be analyzed and data logged to identify history of ailments of particular user/patient. The system possesses the characteristics, such as less intrusiveness to the users and helps the caretakers as well as physicians with comfort in taking care of patients.

The linearity of conventional active-RC filters is limited by the operational transconductance amplifiers (OTAs) used in the integrators. Transconductance-capacitance (Gm-C) filters are fast and can be linear- however, they are sensitive to parasitic capacitances. We explore the Gm-assisted OTA-RC technique, which is a way of combining Gm-C and active-RC integrators in a manner that enhances the linearity and speed of the latter, while adding negligible extra noise or power dissipation. Measurements from a fifth-order Chebyshev filter with 20 MHz bandwidth, designed in a 0.18 μ m CMOS process, demonstrate the efficacy of Gm-assistance in an active-RC integrator.

Plant molecular farming (PMF) is a new branch of plant biotechnology, where plants are engineered to produce recombinant pharmaceutical and industrial proteins in large quantities. As an emerging subdivision of the biopharmaceutical industry, PMF is still trying to gain comparable social acceptance as the already established production systems that produce these high valued proteins in microbial, yeast, or mammalian expression systems. This article reviews the various cost-effective technologies and strategies, which are being developed to improve yield and quality of the plant-derived pharmaceuticals, thereby making plant-based production system suitable alternatives to the existing systems. It also attempts to overview the different novel plant-derived pharmaceuticals and non-pharmaceutical protein products that are at various stages of clinical development or commercialization. It then discusses the biosafety and regulatory issues, which are crucial (if strictly adhered to) to eliminating potential health and environmental risks, which in turn is necessary to earning favorable public perception, thus ensuring the success of the industry.

Small cell lung cancer (SCLC) accounts for 14% of lung cancer diagnoses in the United States and is characterized by rapid onset of chemoresistance and poor clinical outcomes. Once considered a homogeneous disease, recent analyses of SCLC have identified intratumoral heterogeneity (ITH) with respect to NOTCH signaling, ASCL1/NEUROD1 balance and MYC amplification - all of which are potential mechanisms underlying SCLC's aggressive and refractory biology. Unfortunately, patient-derived models of SCLC with which to better characterize the molecular profiles of refractory SCLC are scarce. To address this, we generated circulating tumor cell-derived xenograft (CDX) models from liquid biopsies of patients with treatment-naïve or relapsed SCLC. Each CDX model underwent pathological review to confirm tumors were consistent with SCLC based on histology and standard immunohistochemical markers (e.g., TTF1, chromogranin A, synaptophysin, NCAM). Sequencing of these models revealed mutations typical of SCLC (e.g. TP53, RB1), which were maintained in vivo over multiple passages. Importantly, each model's in vivo response to cisplatin matched the patient's platinum response at the time of CDX generation. At the proteomic level, platinum-resistant models exhibited mTOR activation, increased SOX2 and ATM, and reduced E-cadherin, suggesting a shift toward EMT and cancer stem cell expansion may contribute to resistance. To investigate ITH, we analyzed single-cell gene expression profiles by RNAseq using a droplet-based Chromium Single Cell system that analyzed a filtered subsample of 2000 cells per tumor. Consistent with SCLC, all CDX models contained large numbers of cells expressing neuroendocrine-specific genes (SYP, CHGA). However, Principle Component Analysis revealed that cells from chemosensitive CDX models had distinct expression profiles from resistant models. Using our published EMT gene signature, we found that resistant models had higher proportions of mesenchymal (vs. epithelial) cells. Several other distinctions between sensitive and resistant models were detected at the single-cell level but not in bulk RNA and protein analyses, suggesting that single-cell resolution can identify occult platinum-resistant subpopulations. For example, higher proportions of ASCL1- and DLL3-expressing cells were associated with platinum sensitivity, whereas a shift toward predominant NEUROD1-expression was observed with resistance. Cells expressing each of these three genes were identified across all tumors, suggesting platinum-sensitive and resistant subpopulations are ubiquitous but that even subtle shifts in the fractional distribution of these subsets can exert significant impact on response. These data support further use of single-cell analysis to explore the role of ITH as a driver of drug resistance in SCLC. Citation Format: C. Allison Stewart, Carl M.

The fourth generation mobile phone standards (4G) in widespread use include Long Term Evolution (LTE) and LTE-A (Advanced), which support up to 44 bands internationally, or an aggregate bandwidth of about 1 GHz in TDD and FDD modes. Techniques such as carrier aggregation allow the mobile operator to maximize bandwidth and deliver high data rate to users. As demand for wireless connectivity continues to grow exponentially, a fifth generation (5G) standard is envisioned, with the requirement to deliver higher throughputs, more spectrum-particularly in the mm-wave bands-higher capacity through spatial diversity, and lower latency. The projected deployment date of 5G is in 2019, and various proposals are under consideration. This paper will highlight important implications for the design of transceivers for 5G, particularly those targeting the mm-wave bands.

This paper demonstrates a 240GHz wideband QPSK receiver in 65nm bulk CMOS. A direct-conversion mixer-first architecture is implemented with a 240GHz on-chip antenna. Wideband passive mixers at the front end employ a 240GHz LO and convert the received signal down to baseband. The baseband signal is then amplified using high gain, wide bandwidth amplifiers. The 240GHz LO chain consists of 27GHz/80GHz injection-locked oscillators, 80GHz amplifiers and a frequency tripler. The overall receiver gain is 25dB and the noise figure is 15dB from measurements. This receiver design achieves a data rate of 16Gbps with a power consumption of 260mW.

This paper demonstrates a 240GHz wideband QPSK transmitter in 65nm bulk CMOS. The proposed transmitter employs an 80GHz local oscillator, a quadrature differential hybrid, and a QPSK modulator. Additionally, an 80GHz class-E switching power amplifier is used to efficiently boost the phase-modulated wideband signal. A frequency tripler then regenerates the modulated signal at 240GHz while preserving the QPSK constellation. By using on-chip slotted loop antennas, the transmitter achieves an EIRP of 1dBm. A maximum data rate of 16Gbps is achieved with a total power consumption of 220mW.

The rapid scaling of CMOS technology in the last decade has enabled the design of high speed and efficient digital CMOS circuits. However, the design of RF and mm-wave systems has become more challenging due to inaccuracies in modeling and increased losses in the active and passive devices. This paper presents the design of a 60 GHz linear wideband power amplifier (PA) in deeply scaled 28 nm CMOS technology. The PA utilizes cascode drain-source neutralization to improve stability and low-k transformer techniques to achieve high bandwidth. Using transmission line power combining, the PA delivers a saturated output power of 16.5 dBm with a peak power added efficiency (PAE) of 12.6%. The three stage PA achieves an overall bandwidth of 11 GHz with a peak gain of 24.4 dB.

DC Motors have taken a great evolution from older brushed DC motors to today's BLDC motor. It has wide range of applications and hence it needs to have a better lifetime with higher efficiency. So for giving a higher efficiency, better lifetime and to get a better performance Brushless DC motors are developed. This brushless DC motor provides a greater efficiency with its complexity for controlling as a tradeoff, i.e. to get a better efficiency the complexity of the controlling systems increases. The BLDC motor needs the help of sensor to estimate its rotor position details to get controlled by the controlling circuit, which will directly affects the cost of the system. Now the sensorless controlling mechanisms have been developed which have made the cost lesser and provides better stability. Such an efficient sensorless controlling mechanism is proposed in this paper.

Wheel Loaders are heavy earth movers used for rugged real-time works like Construction, mining, Carrying, Demolition, Excavation and Hauling. Wheel Loaders have only conventional and analog control panels and indicators to monitor the vehicle's engine parameters. The earth mover operators face the problems of using these control panels. This project proposes a solution for the above problem by developing a sophisticated digital display in order to display both text and graphical symbols. The Digital displays are controlled by microcontrollers which analyze the transducer values and provide summarized and efficient parameters to the control panel with high resolution. This would enhance the operation of Wheel loaders in terms of ease-of-use, lane keeping, efficiency, safety and productivity.

This research aims as a proof of concept for a vibration energy harvester using human motion as the energy source. Human motion consists of burst of low frequency vibrational kinetic energy. The high acceleration burst is usually 1. 5 to 2 g when the foot strikes the ground and an ionic polymer metallic composite (IPMC) can be used to harvest this energy via two methods. The first method is via the bending of the IPMC causing the mobile cations to move and produces an output voltage pulse, hence capacitive transduction. Secondly, the IPMC in a beam form that resonate at the low vibration frequency due to its relatively low Young's modulus can scavenge additional secondary energy via external electromagnetic transduction to supplement the primary harvested energy via the IPMC capacitive transduction.

A fully integrated 260GHz OOK transceiver is demonstrated in 65nm CMOS. Communication at 10Gb/s has been verified over a range of 40 mm. The Tx/Rx dual on-chip antenna array is implemented with half-width leaky wave antennas. Each Tx consists of a quadrupler driven by a class-D−1 PA with a distributed OOK modulator, and outputs +5 dBm of EIRP. The Rx uses a double balanced mixer to down-convert to a V-band IF signal that is amplified with a wideband IF driver and demoduated on-chip.

The linearity of conventional active-RC filters is limited by the operational transconductance amplifiers (OTAs) used in the integrators. We propose the Gm-assisted OTA-RC technique, which is a way of combining Gm-C and active-RC integrators in a manner that enhances the linearity and speed of the latter, while adding negligible extra noise or power dissipation. Measurements from a fifth order Chebyshev filter with 20 MHz bandwidth designed in a 0.18µm CMOS process show a 30 dB reduction in intermodulation distortion when Gm-assistance is added to an active-RC filter.

Background: Human identification has been studied since fourteenth century and it has gradually advanced for forensic purposes. Traditional methods such as dental, fingerprint, and DNA comparisons are probably the most common techniques used in this context, allowing fast and secure identification processes. But, in circumstances where identification of an individual by fingerprint or dental record comparison is difficult, palatal rugae may be considered as an alternative source of material. Aim: The present study was done to evaluate the individualistic nature and use of palatal rugae patterns for personal identification and also to test the efficiency of computerized software for forensic identification by photographic superimposition of palatal photographs obtained from casts. Materials and Methods: Two sets of Alginate impressions were made from the upper arches of 100 individuals (50 males and 50 females) with one month interval in between and the casts were poured. All the teeth except the incisors were removed to ensure that only the palate could be used in identification process. In one set of the casts, the palatal rugae were highlighted with a graphite pencil. All the 200 casts were randomly numbered, and then, they were photographed with a 10.1 Mega Pixel Kodak digital camera using standardized method. Using computerized software, the digital photographs of the models without highlighting the palatal rugae were overlapped over the images (transparent) of the palatal rugae with highlighted palatal rugae, in order to identify the pairs by superimposition technique. Incisors were remained and used as landmarks to determine the magnification required to bring the two set of photographs to the same size, in order to make perfect superimposition of images. Results: The result of the overlapping of the digital photographs of highlighted palatal rugae over normal set of models without highlighted palatal rugae resulted in 100% positive identification. Conclusion: This study showed that utilization of palatal photographs is highly viable. The photographic superimposition technique using Adobe Photoshop 8.0 software (used in this study for comparison of palatal rugae) was proved effective for human identification and can be used when ante-mortem data regarding palatal rugae is provided. This study also concluded that palatal rugae are highly individualistic and play an important role as a complementary method in personal identification.

International audience; This article describes the synthesis and characterization of Cobalt Oxide (Co 3 O 4) nanoparticles prepared via the hydrothermal method to examine the behavior of supercapacitor performance. The phase structure and purity of the synthesized nanoparticles were confirmed by XRD and the crystallite size was calculated as 13.76 nm using Scherrer's formula. The structure and morphology of the synthesized samples were characterized by FT-IR, X-ray diffraction (XRD), transmission electron microscopy (TEM), Field Emission Scanning Electron Microscopy (FE-SEM). The electrochemical performance was analyzed using galvanostatic charge and discharge studies (GCD), Cyclic Voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The FTIR and XRD results indicated that the synthesized samples were highly pure wellcrystallized cubic phase. FE-SEM result reveals the synthesized nanoparticles have micro-nano rock-like structure and the SAED pattern confirms the nature of polycrystalline. The electrochemical performance has been examined through CV, GCD, and impedance analysis. The greatest specific capacitance (SCs) value is achieved to be 698.4 F g −1 on 1mA/cm 2 current density which maintains good cyclic stability after 500 cycles.
