Assessment of exposure to radio frequency electromagnetic fields from smart utility meters in GB; part II) numerical assessment of induced SAR within the human body (2017)

Human body exposure to radiofrequency electromagnetic waves emitted from smart meters was assessed using various exposure configurations. Specific energy absorption rate distributions were determined using three anatomically realistic human models. Each model was assigned with age- and frequency-dependent dielectric properties representing a collection of age groups. Generalized exposure conditions involving standing and sleeping postures were assessed for a home area network operating at 868 and 2,450 MHz. The smart meter antenna was fed with 1 W power input which is an overestimation of what real devices typically emit (15 mW max limit). The highest observed whole body specific energy absorption rate value was 1.87 mW kg<sup>-1</sup> , within the child model at a distance of 15 cm from a 2,450 MHz device. The higher values were attributed to differences in dimension and dielectric properties within the model. Specific absorption rate (SAR) values were also estimated based on power density levels derived from electric field strength measurements made at various distances from smart meter devices. All the calculated SAR values were found to be very small in comparison to International Commission on Non-Ionizing Radiation Protection limits for public exposure.

Assessing fitness costs for transgenic<i>Aedes aegypti</i>expressing the GFP marker and transposase genes (2004)

The development of transgenic mosquitoes that are refractory to the transmission of human diseases such as malaria, dengue, and yellow fever has received much interest due to the ability to transform a number of vector mosquito species with transposable elements. Transgenic strains of mosquitoes have been generated with molecular techniques that exhibit a reduced capacity to transmit pathogens. These advancements have led to questions regarding the fitness of transgenic mosquitoes and the ability of transformed mosquitoes to compete and effectively spread beneficial genes through nontransformed field populations, the core requirement of a genetically based control strategy aimed at reducing the spread of mosquito-borne human disease. Here we examine the impact of transgenesis on the fitness of Aedes aegypti, a mosquito that transmits yellow fever. Mosquitoes were altered with two types of transgene, the enhanced GFP gene and two transposase genes from the Hermes and MOS1 transposable elements. We examined the effects of these elements on the survivorship, longevity, fecundity, sex ratio, and sterility of transformed mosquitoes and compared results to the nontransformed laboratory strain. We show that demographic parameters are significantly diminished in transgenic mosquitoes relative to the untransformed laboratory strain. Reduced fitness in transgenic mosquitoes has important implications for the development and utilization of this technology for control programs based on manipulative molecular modification.
Adaptive Pitch-Based Speech Detection for Hands-Free Applications (2006)

This paper proposes a new algorithm for classifying an audio segment as speech or non-speech. The proposed algorithm is capable of handling reverberation and low signal-to-noise environments; therefore, it is suitable for hands-free applications. The algorithm divides an audio segment into frames, estimates the presence of pitch in each frame, and calculates a pitch ratio parameter. This parameter is then used to classify the audio segment. The threshold used in calculating this parameter is adapted to accommodate different environments. The performance of the proposed algorithm is evaluated for different signal-to-noise ratios and different segment sizes using a library of audio segments. The library includes speech segments and nonspeech segments such as fan noise and cocktail noise. Using 0.4 second segments it is shown that the proposed algorithm can achieve a correct decision for 95.7% of the speech segments and 96.7% of the nonspeech segments under reverberant conditions.
The Tectonic Evolution of Interior Oman (1996)

ABSTRACT The evolution of Oman’s onshore sedimentary basins from the Late Precambrian to the Present is reflected by six tectono-stratigraphic units. Unit I, the Precambrian basement, represents continental accretion. Units II and III, Infracambrian to Ordovician, may reflect two periods of rifting, possibly related to Najd movements in western Saudi Arabia. The northeast-southwest trending salt basins formed during this time interval. A classical “steer’s head” basin geometry is developed in North Oman, whereas a less complete rift-sag sequence is preserved in South Oman. Of the entire time-span from Late Silurian to Mid-Carboniferous, only little Devonian (Emsian) sediment is preserved. Unit IV, Late Carboniferous to Mid-Cretaceous, reflects the break-up of Gondwana and the creation of the northeastern and southeastern passive margins of the Arabian Plate. Unit V documents intra-plate deformation related to Late Cretaceous continent-ocean obduction in the north and transpressional movements of the Indian Plate in the east. Unit VI, spanning the Tertiary, represents a return to quiet conditions followed by continent-continent collision in the north. Following Late Eocene uplift, the Gulf of Aden rift developed in the south in the early Oligocene, with sea-floor spreading from the Late Miocene onwards. Salt flow and dissolution, both playing a major role in the configuration of most intra- and post-salt hydrocarbon traps in Oman, are episodic and can be related to tectonic events.
Catalytic Janus Motors on Microfluidic Chip: Deterministic Motion for Targeted Cargo Delivery (2012)

We fabricated self-powered colloidal Janus motors combining catalytic and magnetic cap structures, and demonstrated their performance for manipulation (uploading, transportation, delivery) and sorting of microobjects on microfluidic chips. The specific magnetic properties of the Janus motors are provided by ultrathin multilayer films that are designed to align the magnetic moment along the main symmetry axis of the cap. This unique property allows a deterministic motion of the Janus particles at a large scale when guided in an external magnetic field. The observed directional control of the motion combined with extensive functionality of the colloidal Janus motors conceptually opens a straightforward route for targeted delivery of species, which are relevant in the field of chemistry, biology, and medicine.
Plasmon-polaritons on graphene-metal surface and their use in biosensors (2012)

We studied excitation of surface plasmon-polaritons on graphene-metal surface. The metal surface is functionalized by transfer printing of graphene grown by chemical vapor deposition on copper foils. Surface plasmon resonance characteristics of monolayer and multilayer graphene on the metal surface are presented. We were able to obtain the dispersion relation of graphene-metal surface which reveals the essential feature of the plasmon-polaritons. As an application, we fabricated a surface plasmon resonance sensor integrated with a microfluidic device to study nonspecific physical interaction between graphene layer and proteins.
Single ImageWatermark Retrieval from 3D Printed Surfaces via Convolutional Neural Networks (2018)

In this paper we propose and analyse a method for watermarking 3D printed objects, concentrating on the watermark retrieval problem. The method embeds the watermark in a planar region of the 3D printed object in the form of small semi-spherical or cubic bumps arranged at the nodes of a regular grid. The watermark is extracted from a single image of the watermarked planar region through a Convolutional Neural Network. Experiments with 3D printed objects, produced by filaments of various colours, show that in most cases the retrieval method has a high accuracy rate.
Efectes barocalòrics colossals en cristalls plàstics derivats del neopentà (2016)

Aquest projecte investiga els efectes calorics resultants de l’aplicacio d’un camp hidrostatic
(efectes barocalorics, BCE). Els efectes calorics s’entenen com els canvis d’entropia isotermics o
els canvis de temperatura adiabatics que pateix un material quan es troba sotmes a l’accio d’un
determinat camp extern. L’objectiu es valorar les mostres seleccionades com a possibles
candidates per les noves tecnologies de refrigeracio. Aquestes noves tecnologies son mes
amigables amb el medi ambient que la compressio de gasos, el procediment mes utilitzat
actualment.
Per determinar l’efecte barocaloric, en la fase d’experimentacio, s’han emprat la calorimetria
d’escombrat diferencial, DSC, i l’analisi termic diferencial sota pressio, DTA. Aquests metodes
experimentals permeten caracteritzar les transicions de fase de les mostres, indicant la
temperatura de transicio i oferint dades que amb un determinat processament donaran magnitud
a l’efecte barocaloric.
Les mostres escollides per realitzar l’estudi son l’AMP i el PG, ambdos derivats del neopenta. Es
tracta de cristalls plastics que presenten fases plastiques i una transicio de primer ordre en estat
solid, durant la qual es donen canvis importants de volum i d’entropia. Aquests grans canvis
d’entropia tenen lloc per la calor latent associada al canvi de fase i per les nostres mostres
provocaran un efecte barocaloric gegant.
A partir dels resultats obtinguts, s’ha observat que la temperatura de transicio de les dues
mostres augmenta quan s’incrementa la magnitud del camps hidrostatics. Segueixen una
tendencia lineal en els dos casos: 5.9 K/kbar i 8.7 K/kbar pels escalfaments i refredaments de
l’AMP respectivament i 7.7 K/kbar i 9.0 K/kbar per escalfaments i refredaments del PG. S’han
trobat els canvis d’entropia de les transicions a diferents pressions i posteriorment l’efecte
barocaloric, el canvi d’entropia isoterm maxim. S’han assolit els seguents BCE gegants: 487.3
J·kg1
·K-1 per una pressio de 2.29 kbar en PG i per l’AMP de 646 J·kg-1
·K-1 a 2.56 kbar.
Es pot concloure que a mes de l’efecte barocaloric maxim, hi ha altres parametres importants per
determinar si una mostra es optima per ser utilitzada en les noves tecnologies de refrigeracio. La
histeresi te un paper fonamental per veure si el material podria treballar en una maquina amb
funcionament ciclic, com es el cas del les maquines refrigeradores.

Los avances en anestesiología y cuidados intensivos perioperatorios han hecho posible realizar procedimientos complejos en cirugía pediátrica. Las mejoras tecnológicas no evitan errores, y aquellos atribuibles a una actitud incorrecta, negligencia, exceso de confianza, así como la práctica no basada en la evidencia tienden a producir complicaciones. Una adecuada cultura de seguridad necesita involucrar a todo el personal y formar equipos de alto rendimiento. Este articulo describe el proceso de implementación de un listado de verificación quirúrgico (LVQ), para desarrollar una cultura de seguridad y un cambio de actitud en un hospital universitario de la India.
A Highly Reproducible Continuous Process for Hydroxyapatite Nanoparticles Synthesis (2009)

This work presents a continuous process for producing hydroxyapatite nanoparticles (NanoXIM) in a network reactor, NETmix, fed by a calcium solution, a phosphorus solution and an alkaline solution. Hydroxyapatite is considered a biomaterial, used as: food additives and nutritional supplements; bone graft for bone replacement, growth and repair; biocements and coating of metallic implant. Some of the most recent applications include their use in cosmetics, toothpaste and in esthetical treatments for diminishing wrinkles by stimulating conjunctive tissue formation. The proposed process enables the micromixing control, which is essential to form nanometric structures, but it is also a determining factor in the crystals purity, crystallinity and morphology. The reactants distribution scheme at the inlet of the reactor and along the reactor, performed continuously or varying in time, is also a crucial factor to programme the properties of reactant media along the reactor, such as the pH, the supersaturation degree, the Ca/P molar ratio, and the temperature. The calcium phosphate nanoparticles suspension that exits the reactor is submitted to further aging, separation, drying, sintering and milling processes.
18.6 A 0.5nJ/pixel 4K H.265/HEVC codec LSI for multi-format smartphone applications (2015)

A 4K×2K H.265/HEVC video codec chip is fabricated in a 28nm CMOS process with a core area of 2.16mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . This LSI chip integrates a dual-standard (H.265 and H.264) video codec and a series of prevalent (VC-1, WMV-7/8/9, VP-6/8, AVS, RM-8/9/10, MPEG-2/4) decoders into a single chip. It contains 3,558K logic gates and 308KB of internal SRAM. Moreover, it simplifies intra/inter-rate-distortion optimization (RDO) processes and reduces external bandwidth via line-store SRAM pool (LSSP) and data-bus translation (DBT) techniques. For smartphone applications, it completes real-time HEVC encoding and decoding with 4096×2160 resolution and 30fps, and consumes 126.73mW (0.5nJ/pixel) of core power dissipation at 0.9V, at 494MHz (encoding) and 350MHz (decoding). 1080HD and 720HD resolutions are reported as well. The chip features are summarized in Fig. 18.6.1.
Learning Covariant Feature Detectors (2016)

Local covariant feature detection, namely the problem of extracting viewpoint invariant features from images, has so far largely resisted the application of machine learning techniques. In this paper, we propose the first fully general formulation for learning local covariant feature detectors. We propose to cast detection as a regression problem, enabling the use of powerful regressors such as deep neural networks. We then derive a covariance constraint that can be used to automatically learn which visual structures provide stable anchors for local feature detection. We support these ideas theoretically, proposing a novel analysis of local features in term of geometric transformations, and we show that all common and many uncommon detectors can be derived in this framework. Finally, we present empirical results on translation and rotation covariant detectors on standard feature benchmarks, showing the power and flexibility of the framework.
Angiotensin-(1-12) is an alternate substrate for angiotensin peptide production in the heart (2008)

Identification of angiotensin-(1-12) as an intermediate precursor derived directly from angiotensinogen led us to explore whether the heart has the capacity to process angiotensin-(1-12) into biologically active angiotensin peptides. The generation of angiotensin I, angiotensin II, and angiotensin-(1-7) from exogenous angiotensin-(1-12) was evaluated in the effluent of isolated perfused hearts mounted on a Langendorff apparatus in three normotensive and two hypertensive strains: Sprague-Dawley, Lewis, congenic mRen2.Lewis, Wistar-Kyoto, and spontaneously hypertensive rats. Hearts were perfused with Krebs solution for 60 min before and after the addition of angiotensin-(1-12) (10 nmol/l). Angiotensin-(1-12) caused the rapid appearance of both angiotensin I and angiotensin II in the perfusate that peaked between 30 and 60 min of recirculation. Production of angiotensin-(1-7) from exogenous angiotensin-(1-12) rose steadily over the course of the 60-min experiment. These data directly demonstrate that angiotensin-(1-12) is a substrate for the formation of angiotensin peptides in cardiac tissue. This finding further suggests that this angiotensinogen-derived product is a previously unrecognized important precursor peptide to the renin-angiotensin system cascade.

Breast conservation is an effective treatment for patients with synchronous ipsilateral breast cancers.
Surface interactions of SiO2-nanofluids with 100Cr6-steel during machining (2022)

Nanofluids consisting of nanoscale particles in a carrier medium are increasingly used as cutting fluids in minimum quantity lubrication (MQL) due to their enhanced cooling and lubricating properties. These improvements have already been demonstrated, but a fundamental understanding of the underlying mechanisms and particle-surface interactions is still lacking. Therefore, in this research nanofluids are used in tribological applications and the interactions of the particles with the workpiece surface are investigated. A tribological test rig is used and various SiO2-based nanofluids are applied under different machining conditions. Special attention is given to the deposition of the particles on the workpiece surface.
Self-triggered Communication Enabled Control of Distributed Generation in Microgrids (2015)

Efficient utilization of distributed generation (DG) resources in a microgrid requires coordinated control, which can be realized using multiagent-based system model. The coordinated control requires information exchange among the distributed agents, which can be implemented using either periodic or need-based aperiodic data transmission. For reducing the data communication requirements among the agents, an aperiodic self-triggered communication-based coordinated control is proposed. Centralized as well as distributed self-triggered coordinated control is implemented. The performance evaluation results show that self-triggered aperiodic communication requires lower data rates, while delivering the same performance as that of periodic sampled data control.
Comment on “Type I CD20 Antibodies Recruit the B Cell Receptor for Complement-Dependent Lysis of Malignant B Cells” (2018)

We read with great interest the article by Engelberts and colleagues ([1][1]), which concludes that presence of the BCR on a CD20-expressing cell line can render these cells susceptible for lysis via a type I Ab with a missing or defective C1q binding site. This phenomenon was termed accessory
ENGAGE-1: A first in human study of the OX40 agonist GSK3174998 alone and in combination with pembrolizumab in patients with advanced solid tumors. (2016)

TPS3107 Background: OX40 (CD134) is a potent costimulatory tumor necrosis factor receptor expressed on activated CD4+ and CD8+ T cells. OX40 agonism promotes T-cell division and survival, resulting in stimulation of both immune effector and memory functions, while also blocking the suppressive function of regulatory T cells. This holds potential to overcome immune resistance and enhance immune mediated anti-tumor activity with OX40 agonism, particularly in combination with checkpoint inhibition. GSK3174998 is a humanized IgG1 anti-OX40 agonistic monoclonal antibody identified through collaboration with MD Anderson Cancer Center and is currently in phase I development. Methods: This is an open-label, non-randomized, multicenter study of GSK3174998 administered alone and in combination with pembrolizumab in patients (pts) with selected advanced or recurrent solid tumors: non-small cell lung cancer, squamous cell carcinoma of the head and neck, renal cell carcinoma, melanoma, bladder, soft tissue sarcoma, triple-negative breast cancer, and colorectal carcinoma displaying microsatellite instability. The study will be conducted in 2 parts in approximately 180 pts. Primary objectives are to determine safety, tolerability, and maximum tolerated or administered dose of GSK3174998 as a single agent (Part 1) and when administered in combination with 200 mg pembrolizumab (Part 2). Secondary objectives include evaluation of antitumor activity, response rate and duration, progression-free survival, and overall survival, pharmacokinetics, pharmacodynamic activity in the blood and tumor microenvironment, and immunogenicity. Adverse events will be monitored using NCI CTCAE v. 4.0. Radiographic imaging will be obtained every 12 weeks to assess clinical response defined by immune-related RECIST. Tumor biopsies and blood samples will be collected before and during treatment to allow investigation of candidate biomarkers which may predict clinical response. As of Feb 1, 2016, Cohorts 1 and 2 have completed without DLT and enrollment to Cohort 3 is ongoing. Clinical trial information: NCT02528357.
<i>SLC40A1</i> c.1402G→A Results in Aberrant Splicing, Ferroportin Truncation after Glycine 330, and an Autosomal Dominant Hemochromatosis Phenotype (2007)

A dual band printed dipole antenna with spiral structure for WLAN application (2005)

In this letter, the design procedure and electrical performance of a dual band (2.4/5.8GHz) printed dipole antenna using spiral structure are proposed and investigated. For the first time, a dual band printed dipole antenna with spiral configuration is proposed. In addition, a matching method by adjusting the transmission line width, and a new bandwidth broadening method varying the distance between the top and bottom spirals are reported. The operating frequencies of the proposed antenna are 2.4GHz and 5.8GHz which cover WLAN system. The proposed antenna achieves a good matching using tapered transmission lines for the top and bottom spirals. The desired resonant frequencies are obtained by adjusting the number of turns of the spirals. The bandwidth is optimized by varying the distance between the top and bottom spirals. A relative position of the bottom spiral plays an important role in achieving a bandwidth in terms of 10-dB return loss.
Inhibition of testicular germ cell apoptosis and differentiation in mice misexpressing Bcl-2 in spermatogonia (1996)

During normal spermatogenesis, more than half of the germ cells undergo apoptosis, but the physiological significance and molecular mechanisms of this programmed cell death are largely unknown. Because Bcl-2 functions as a death repressor, we have investigated the effect of misexpressing Bcl-2 in spermatogonia in transgenic mice using the human bcl-2 cDNA under the control of the human polypeptide chain elongation factor 1alpha (EF-1alpha) promoter. In the 2-week-old transgenic testes, exogenous Bcl-2 was expressed in spermatogonia and massive accumulation of spermatogonia was observed in seminiferous tubules by 4 weeks. At this time, only a few spermatocytes were apparent, and the accumulated cells degenerated, leading to vacuolization in some seminiferous tubules by 7 weeks. In older transgenic mice, abnormal accumulation of spermatogonia and degeneration of these germ cells was still observed, but some seminiferous tubules in which the level of Bcl-2 expression was reduced recovered normal spermatogenesis. These observations indicate that spermatogonial apoptosis is part of the normal program of mammalian spermatogenesis and is regulated by a pathway affected by Bcl-2.
