Home automation and security for mobile devices (2011)

As mobile devices continue to grow in popularity and functionality, the demand for advanced ubiquitous mobile applications in our daily lives also increases. This paper deals with the design and implementation of HASec, a Home Automation and Security system for mobile devices, that leverages mobile technology to provide essential security to our homes and associated control operations. In particular, with the help of mobile devices, HASec operates and controls motion detectors and video cameras for remote sensing and surveillance, streams live video and records it for future playback, and finally manages operations on home appliances, such as turning ON/OFF a television or microwave or altering the intensity of lighting around the house. The proposed home security solution hinges on our novel integration of cameras and motion detectors into a mobile application. For instance, when motion is detected, the cameras automatically initiate recording and the iOS device alerts the homeowner of the possible intrusion. HASec has two main components interacting with each other: the iOS application that executes on the mobile device and server-side scripts that run in a cloud. Although HA-Sec is implemented for Apple's iOS devices such as iPhone, iPod Touch, and iPad, it can be easily ported to other mobile platforms. Furthermore, our application is not only limited to smart-phones but also can be used by feature phones through their browsers.
Tuning the solubility of boron nitridenanosheets in organic solvents by using block copolymer as a “Janus” modifier (2012)

The solubility of boron nitride nanosheets (BNNSs) in different organic solvents is smartly tuned by using a "Janus" modifier, P(S-b-MMA), which enriches our choice of organic solvents for BNNSs, including low-boiling-point acetone, alkanes, cycloalkanes and benzene series, that are viewed as nonsolvents of BNNSs.
Phase transition-governed opal–VO2 photonic crystal (2001)

Three-dimensional opal–VO2 photonic crystals were prepared by the chemical bath deposition technique. The x-ray diffraction and Raman spectroscopic data confirm the crystalline perfection of VO2 impregnated into synthetic opal pores. It is shown from the optical reflectivity measurements that the photonic bandgap of the opal–VO2 composite is governed by the phase transition in VO2.
A Resolution for Shared Memory Conflict in Multiprocessor System-on-a-Chip (2012)

Now days, manufacturers are focusing on increasing the concurrency in multiprocessor system-on-a-chip (MPSoC) architecture instead of increasing clock speed, for embedded systems. Traditionally lock-based synchronization is provided to support concurrency; as managing locks can be very difficult and error prone. Transactional memories and lock based systems have been extensively used to provide synchronization between multiple processors [1] in general-purpose systems. It has been shown that locks have numerous shortcomings over transactional memory in terms of power consumption, ease of programming and performance. In this paper, we propose a new semaphore scheme for synchronization in shared cache memory in an MPSoC. Moreover, we have evaluated and compared our scheme with locks and transactions in terms of energy consumption and cache miss rate using SimpleScalar functional simulator.

Differential Control of Bmal1 Circadian Transcription by REV-ERB and ROR Nuclear Receptors (2005)

Circadian rhythms result from feedback loops involving clock genes and their protein products. In mammals, 2 orphan nuclear receptors, REV-ERBalpha and RORalpha, play important roles in the transcription of the clock gene Bmal1. The authors now considerably extend these findings with the demonstration that all members of the REV-ERB (alpha and beta) and ROR (alpha, beta, and gamma) families repress and activate Bmal1 transcription, respectively. The authors further show that transcription of Bmal1 is the result of competition between REV-ERBs and RORs at their specific response elements (RORE). Moreover, they demonstrate that Reverb genes are similarly expressed in the thymus, skeletal muscle, and kidney, whereas Ror genes present distinct expression patterns. Thus, the results indicate that all members of the REV-ERB and ROR families are crucial components of the molecular circadian clock. Furthermore, their strikingly different patterns of expression in nervous and peripheral tissues provide important insights into functional differences between circadian clocks within the organism.
Admittance-transforming injection-locked frequency divider and low-supply-voltage current mode logic divider (2010)

A injection-locked frequency divider (ILFD) with a 0.8-V current mode logic (CML) frequency divider are presented in this paper. These two frequency dividers are fabricated and integrated in 0.13-µm CMOS technology. The proposed ILFD adopts the admittance-transforming to widen the locking range. To achieve low-supply-voltage in CML frequency divider, the transconductance stage of CML divider is replaced by the inductance. Under 0 dBm injected power, the measured results show that the proposed ILFD have 22.8 % bandwidth from 40.5-to-50.9 GHz. Furthermore, the divider-by-four frequency divider composed of an ILFD and CML divider are measured with locking range from 42 to 45 GHz. The ILFD and CML divider consume 3.6 mW and 8 mW dc power from 0.6 V and 0.8 V supply voltage, respectively.
Differences between Plant and Animal Myb Domains Are Fundamental for DNA Binding Activity, and Chimeric Myb Domains Have Novel DNA Binding Specificities (1997)

Several Myb domain proteins have been identified in plants, in which they play important regulatory roles in specific cellular processes. Plant and animal Myb domains have significant differences, but how these differences are important for function is not yet understood. The P gene encodes a Myb domain protein that activates a subset of flavonoid biosynthetic genes in maize floral organs. P and v-Myb bind different DNA sequences in vitro. Here we show that the Myb domain is solely responsible for the sequence-specific DNA binding activity of P, which binds DNA only in the reduced state. Differences in the DNA binding domains of v-Myb and P, which are conserved among animal and plant Myb domains, are fundamental for the high affinity DNA binding activity of these proteins to the corresponding binding sites but are not sufficient for the distinct DNA binding specificities of P and v-Myb. We conclude that significant structural differences distinguish plant from animal Myb domains. A chimeric Myb domain with a novel DNA binding specificity was created by combining Myb repeats of P and v-Myb. This approach could be used to artificially create novel Myb domains and to target transcription factors to genes containing specific promoters or to modify Myb-mediated interactions with other cellular factors.
Learning Human Identity From Motion Patterns (2016)

We present a large-scale study exploring the capability of temporal deep neural networks to interpret natural human kinematics and introduce the first method for active biometric authentication with mobile inertial sensors. At Google, we have created a first-of-its-kind data set of human movements, passively collected by 1500 volunteers using their smartphones daily over several months. We compare several neural architectures for efficient learning of temporal multi-modal data representations, propose an optimized shift-invariant dense convolutional mechanism, and incorporate the discriminatively trained dynamic features in a probabilistic generative framework taking into account temporal characteristics. Our results demonstrate that human kinematics convey important information about user identity and can serve as a valuable component of multi-modal authentication systems. Finally, we demonstrate that the proposed model can also be successfully applied in a visual context.
Indications for Hysterectomy (1993)

Hysterectomy is second only to cesarean section as the most frequently performed major operation in the United States1. Data from the National Hospital Discharge Survey (NHDS) indicate that approximately 590,000 hysterectomies are performed annually1. Although there appears to be a downward trend in the rate since the mid-1980s, it is not yet known whether a true decline has occurred, because there have been recent changes in the NHDS sampling method1,2. By the age of 60, over one third of U.S. women have undergone hysterectomy2. The annual hospital costs for the operation currently exceed $5 billion. . . .
Two new compounds by reaction of taurolidine with methylene glycol (1999)

The compounds 7- oxa- 2[A] 6 - thia- 1,5 - diazabicyclo- [3.3.1]nonane-2,2-dione (CsHIoN203S) and 7-{[2- (2,2-dioxo- 2[A] 6- thia- 1,5,7 - triazabicyclo [3.3.1 ] non-7- yl)ethyl] sulfonyl }-2[A]6-thia - 1,5,7-triazabicyclo [ 3.3.1 ]- nonane-2,2-dione (CI2H24N606S3) are produced when taurolidine is reacted with an excess of methylene glycol. The saturated six-membered heterocyclic tings in both compounds adopt distorted chair conformations.
Models Relating Individual Tree Basal Area Growth Rates to Tree Basal Areas in Even-Aged, Monoculture Forest Stands (2022)

As trees grow larger in even-aged, monoculture forests, stand density increases, taller trees shade smaller trees and a group of smaller, suppressed trees develops that may show little or no growth. Subsequent mortality is most common from this group. This work compares three models that may describe well the relationship between individual tree basal area growth rates and tree basal areas in a forest stand when a suppressed group of trees is present or not. The models are tested using a large collection of data from permanent sample plots in blackbutt (Eucalyptus pilularis Smith) forests in subtropical eastern Australia. An example is given for one stand showing how model parameter values may change as the stand ages; this illustrates how these models have potential for use in the first stage of model development to relate individual tree growth rates to tree sizes and stand characteristics. Such models may then be used widely across the forest population under consideration.
Comparative benefits of various automotive navigation and routing technologies (2002)

The first practical in-vehicle automotive navigation systems utilized dead reckoning combined with digital map-matching to keep track of vehicle positions and to show them in real time on digital map displays. Global Positioning Satellites (GPS) and differential GPS have provided significant navigation system improvements when combined with dead-reckoning, and they have enabled alternative navigation systems that operate without dead reckoning. The introduction of map databases with accurate connectivity, directionality, and turn-restriction attributes have permitted automatic computation of optimum routes as well as presentation of turn-by-turn route-guidance instructions for driving those routes. This paper looks at advantages and limitations of various automobile location and routing techniques, and discusses how limitations can be overcome by combining techniques. Trade-offs between features, performance, and cost are also presented for some specific implementations.
Automated Algorithm Selection on Continuous Black-Box Problems by Combining Exploratory Landscape Analysis and Machine Learning (2018)

In this article, we build upon previous work on designing informative and efficient Exploratory Landscape Analysis features for characterizing problems' landscapes and show their effectiveness in automatically constructing algorithm selection models in continuous black-box optimization problems. Focusing on algorithm performance results of the COCO platform of several years, we construct a representative set of high-performing complementary solvers and present an algorithm selection model that, compared to the portfolio's single best solver, on average requires less than half of the resources for solving a given problem. Therefore, there is a huge gain in efficiency compared to classical ensemble methods combined with an increased insight into problem characteristics and algorithm properties by using informative features. The model acts on the assumption that the function set of the Black-Box Optimization Benchmark is representative enough for practical applications. The model allows for selecting the best suited optimization algorithm within the considered set for unseen problems prior to the optimization itself based on a small sample of function evaluations. Note that such a sample can even be reused for the initial population of an evolutionary (optimization) algorithm so that even the feature costs become negligible.
Diffraction theory for an achromatic Fourier transformation (1981)

A three-lens achromatic Fourier transform system is analyzed in the context of paraxial Fresnel diffraction theory. From the analysis a general solution for the required wavelength dependence of the various lenses is found. A particular arrangement of the general system is then considered. Using first-order lens design principles, it is shown that each dispersive lens can be fabricated using a holographic zone lens and glass element cascade. The paraxial chromatic aberrations of the resulting system are calculated. It is found that this system design yields an achromatic transformation that is well corrected (paraxially) over the entire visible spectrum.
A Performance Study of CPRI over Ethernet with IEEE 802.1Qbu and 802.1Qbv Enhancements (2015)

There has been a debate on whether or not Ethernet, a highly cost effective technology, could meet the stringent latency and jitter requirements imposed by CPRI. To facilitate the discussion, we conducted simulations to understand how Ethernet performs when carrying CPRI traffic with the two Ethernet enhancements, currently being standardized by IEEE, namely frame preemption (802.1Qbu) and scheduled traffic (802.1Qbv). Our simulation results led to two conclusions: 1) Ethernet networks with or without frame preemption, regardless of being shared or dedicated to CPRI traffic, can not meet the CPRI jitter requirement of 8:138 ns, confirming a widely hold belief; 2) Ethernet with the enhancement of scheduled traffic in conjunction with a well defined scheduling algorithm could significantly lower or even completely remove jitter thus could meet CPRI jitter requirement. To the best of our knowledge, this paper is among the first to study the performance of Ethernet with IEEE 802.1Qbu and 802.1Qbv enhancements and to demonstrate by simulation that Ethernet with scheduled traffic could meet CPRI jitter requirement.
Characterization of acoustic droplet formation in a microfluidic flow-focusing device (2011)

Local control of droplet formation with acoustic actuation in a microfluidic flow-focusing device is investigated, and the effects of acoustic voltage, frequency, flow-rate ratio, fluid viscosity, and flow vorticity are characterized. Acoustic actuation is provided to affect droplet breakup in the squeezing regime by imposing periodic oscillation to the fluid-fluid interface and, therefore, a periodic change in its curvature at the cross-junction of the device. Time reduction is observed for the three key stages of droplet breakup in the squeezing regime: dispersed phase flow-front advancement into the orifice, pressure buildup upstream and within the orifice together with liquid inflation downstream, and finally the thinning and pinch-off of the liquid thread. It is found that acoustic actuation has less of an effect on droplet size for the continuous phase with a higher viscosity due to the restrained interfacial vibration under a high shear stress environment. Periodic velocity flow fields within the dispersed phase at different phases of one oscillation cycle are calculated based on the results from phase-averaged microresolution-particle-image velocimetry (μPIV). The oscillation paths for the points of maximum vorticities of phase-averaged velocity components are traced, which reveals that the motion is mainly along the y direction.
A first step towards translating evidence into practice: heartfailure in a community practice-based research network (2004)

The validity of an EHR problem list entry of HF was poor. The problem list validity could be enhanced through reconciliation with other data sources. Inaccurate EHR problem lists may have clinical consequences, including underprescribing of beneficial therapies.
A complete description of the dispersion relation for thin metal film plasmon-polaritons (1990)

A versatile numerical method is used to solve the plasmon-polariton dispersion relation for a planar thin-metal-film geometry. A complete description of the variation of effective-mode index and propagation length with metal thickness and cover index is presented for all four modes. The spatial distribution of these modes is calculated explicitly. The effects of a nonideal metal film and of dielectric loss in the cover material is considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Organization of projections from the ventromedial nucleus of the hypothalamus: A <i>Phaseolus vulgaris</i>‐Leucoagglutinin study in the rat (1994)

The organization of projections from the four parts of the ventromedial nucleus (VMH) and a ventrolaterally adjacent region tentatively identified as the tuberal nucleus (TU) have been analyzed with small injections of the anterograde axonal tracer Phaseolus vulgaris-leucoagglutinin (PHA-L). Extrinsic and intranuclear projections of each part of the VMH display clear quantitative differences, whereas the overall patterns of outputs are qualitatively similar. Overall, the VMH establishes massive intrahypothalamic terminal fields in other parts of the medial zone, tending to avoid the periventricular and lateral zones. The ventrolateral VMH is more closely related to other parts of the hypothalamus that also express gonadal steroid hormone receptors, including the medial preoptic, tuberal, and ventral premammillary nuclei, whereas other parts of the VMH are more closely related to the anterior hypothalamic and dorsal premammillary nuclei. All parts of the VMH project to the zona incerta (including the A13 region) and parts of the midline thalamus, including the paraventricular and parataenial nuclei and nucleus reuniens. The densest inputs to the septum are to the bed nuclei of the stria terminalis, where the ventrolateral and central VMH innervate the anteroventral and anterodorsal areas and transverse and interfascicular nuclei, whereas the anterior and dorsomedial VMH innervate the latter two. The central, lateral, and medial amygdalar nuclei receive substantial inputs from various parts of the VMH. Other regions of the telencephalon, including the nucleus accumbens and the piriform-amygdaloid, infralimbic, prelimbic, anterior cingulate, agranular insular, piriform, perirhinal, entorhinal, and postpiriform transition areas, also receive sparse inputs. All parts of the VMH send a massive, topographically organized projection to the periaqueductal gray. Other brainstem terminal fields include the superior colliculus, peripeduncular area, locus coeruleus, Barrington's nucleus, parabrachial nucleus, nucleus of the solitary tract, and the mesencephalic, pontine, gigantocellular, paragigantocellular, and parvicellular reticular nuclei. The projections of the TU are similar to, and a subset of, those from the VMH and are thus not nearly as widespread as those from adjacent parts of the lateral hypothalamic area. Because of these similarities, the TU may eventually come to be viewed most appropriately as the lateral component of the VMH itself. The functional implications of the present findings are discussed in view of evidence that the VMH plays a role in the expression of ingestive, affective, and copulatory behaviors.
Applications of NLP Techniques to computer-assisted Authoring of Test Items for Elementary Chinese (2010)

The authors report an implemented environment for computer-assisted authoring of test items and provide a brief discussion about the applications of NLP techniques for computer assisted language learning. Test items can serve as a tool for language learners to examine their competence in the target language. The authors apply techniques for natural language processing to help teachers prepare test items for elementary Chinese. Teachers can then compile the test items to form test sheets for formal examinations on the Internet. The system can record the results of the tests for post-test analysis of students' achievements so that teachers can gain insight into the distributions over students' competence levels and can adjust the teaching activities for the students who may need individualized care. At this moment, the system offers assistance for authoring test items for basic listening comprehension, cloze tests, incorrect-character identification, sentence reconstruction and usage of measure words.
