We can hear you with Wi-Fi! (2014)

Recent literature advances Wi-Fi signals to "see" people's motions and locations. This paper asks the following question: Can Wi-Fi "hear" our talks? We present WiHear, which enables Wi-Fi signals to "hear" our talks without deploying any devices. To achieve this, WiHear needs to detect and analyze fine-grained radio reflections from mouth movements. WiHear solves this micro-movement detection problem by introducing Mouth Motion Profile that leverages partial multipath effects and wavelet packet transformation. Since Wi-Fi signals do not require line-of-sight, WiHear can "hear" people talks within the radio range. Further, WiHear can simultaneously "hear" multiple people's talks leveraging MIMO technology. We implement WiHear on both USRP N210 platform and commercial Wi-Fi infrastructure. Results show that within our pre-defined vocabulary, WiHear can achieve detection accuracy of 91% on average for single individual speaking no more than 6 words and up to 74% for no more than 3 people talking simultaneously. Moreover, the detection accuracy can be further improved by deploying multiple receivers from different angles.
Antidepressants and Sexual Dysfunction: Mechanisms and Clinical Implications (2014)

Treatment with selective serotonin reuptake inhibitors (SSRIs) and serotonin/norepinephrine reuptake inhibitors (SNRIs) is associated with SD. Use of other antidepressants, such as bupropion, mirtazapine, nefazodone, and vilazodone, have been associated with less SD compared with SSRIs; furthermore, some of the mentioned antidepressants have been used in the treatment of SD induced by SSRIs and SNRIs.
EDTA removes formation damage at Prudhoe Bay (1982)

Formation damage has been observed in some wells of the Prudhoe Bay Field. Laboratory and field testing confirmed that the primary cause of damage was the buildup of calcium carbonate scale either in the perforation tunnels or in the formation sandstone near the wellbore. Conventional acid treatments could dissolve this scale, but scale reprecipitation from the spent acid caused rapid productivity decline. A scale removal treatment using Na/sub 2/H/sub 2/EDTA has been developed that can effectively dissolve scale and chelate the dissolved metal ions. Chelation of the dissolved scale prevents scale reprecipitation. Of the 25 Prudhoe Bay wells acidized with EDTA, 19 have responded with a significant productivity increase. In 17 of these wells, productivity has been sustained after treatment.
Age-dependent cerebrovascular dysfunction in a transgenic mouse model of cerebral amyloid angiopathy (2007)

The Tg2576 transgenic mouse model of human cerebral amyloid angiopathy is characterized by age-dependent cerebrovascular deposition of amyloid-beta (Abeta) starting from 9 months of age and progressively worsening to involve most pial arterioles by 18 months; soluble Abeta levels are elevated long before vascular deposition takes place in this model. It has been suggested that elevated soluble Abeta levels alone are sufficient to impair cerebral blood flow (CBF) regulation thereby contributing to the early progression of Alzheimer's disease. Using laser speckle flowmetry through an intact skull, we studied the impact of elevated soluble Abeta levels and vascular Abeta deposition on a wide range of CBF responses to evaluate vasodilation and vasoconstriction in young or aged Tg2576 mice. Nineteen-month-old Tg2576 with severe vascular Abeta deposits showed an attenuated hyperaemic response during hypercapnia and whisker stimulation compared to wild-type littermates. The anticipated increase in CBF due to isoflurane anaesthesia was also suppressed, as were the typical hypoperfusion responses during cortical spreading depression and alpha-chloralose anaesthesia. The responses of 8-month-old Tg2576 with elevated soluble Abeta levels, but without vascular Abeta deposition, did not differ from age-matched controls. In conclusion, our data suggest that vascular Abeta deposition is associated with impaired vasodilator as well as vasoconstrictor responses to a wide range of stimuli. These responses do not differ from controls when studied non-invasively prior to vascular Abeta deposition, thus challenging the view that elevated soluble Abeta levels are sufficient to cause cerebrovascular dysfunction.
Recombinant interleukin 12 cures mice infected with Leishmania major. (1993)

Resistant C57BL/6 mice infected with Leishmania major are self-healing, whereas susceptible BALB/c mice fail to contain cutaneous infection and subsequently undergo fatal visceral dissemination. These disparate outcomes are mediated by dissimilar expansions of T helper type 1 (Th1) and Th2 CD4+ T lymphocyte subsets in vivo during cure and progression of disease. Because interleukin 12 (IL-12) has potent T cell growth and interferon gamma (IFN-gamma) stimulatory effects, we studied its effect on CD4+ T cell differentiation during murine leishmaniasis. Treatment with recombinant murine (rMu)IL-12 during the first week of infection cured 89% of normally susceptible BALB/c mice, as defined by decreased size of infected footpads and 1,000-10,000-fold reduced parasite burdens, and provided durable resistance against reinfection. Cure was associated with markedly depressed production of IL-4 by lymph node cells cultured with antigen or mitogen, but preserved or increased production of IFN-gamma relative to untreated mice. IL-4 and IFN-gamma mRNA associated with CD4+ T lymphocytes isolated from infected lymph nodes showed similar reciprocal changes in response to rMuIL-12 therapy. A single injection of anti-IFN-gamma monoclonal antibody abrogated the protective effect of rMuIL-12 therapy and restored Th2 cytokine responses. We conclude that rMuIL-12 prevents deleterious Th2 T cell responses and promotes curative Th1 responses in an IFN-gamma-dependent fashion during murine leishmaniasis. Since BALB/c leishmaniasis cannot be cured with rMuIFN-gamma alone, additional direct effects of IL-12 during T cell subset selection are suggested. Because rMuIL-12 is uniquely protective in this well-characterized model of chronic parasitism, differences in IL-12 production may underlie heterogenous host responses to L. major and other intracellular pathogens.
Immediate Warning of Local Overheating in Electric Machines by the Detection of Pyrolysis Products (1973)

A device employing an ion chamber has been developed for the sensitive, reliable, and very rapid detection of local ovetheatingin a gas-cooled electric machine before extensive damage can result. The device detects the presence of pyrolysis products generated by the thermal decomposition of organic materials such as insulations and polymers. The pyrolysis products include particles of the size of condensation nuclei (about 0.001 to 0.1 microns), and smaller, which have such a pronounced effect on the ion current in the ion chamber that a definite signal is obtained from a hot spot as small as one square inch in area in a large hydrogen-cooled generator. A considerable amount of test and operating experience has been acquired.
<title>Three-dimensional microscopic modifications in glasses by a femtosecond laser</title> (1999)

We examined the feasibility of making various microscopic modifications in glasses by ultra-short pulses. It was confirmed that permanent refractive index changes, photo- reduction of samarium ions, the phenomenon of long-lasting phosphorescence, and creation of microcrystals with second- order nonlinear optical functions can be produced with a femtosecond pulse laser only in selective internal areas in glasses. By using a femtosecond laser with a high repetition rate, permanent optical waveguides can be successfully written in various glasses, where refractive index changes are continuously induced along a path traversed by focal point. We also confirmed that only rare earth ions of the core region in the waveguides are reduced by the laser irradiation.
A Study of Low-Noise Preamplifier Systems for Use with Room Temperature Mercuric Iodide (Hgi2) X-Ray Detectors (1981)

An analysis of different preamplification systems for use with room temperature mercuric iodide x-ray detectors has been performed. Resistor-, drain-, and light-feedback preamplifiers have been studied. Energy resolution values of 295 eV (FWHM) for an Fe-55 source (5.9 keV) and 225 eV (FWHM) for a pulser have been obtained with both the detector and the input FET at room temperature using a pulsed-light feedback preamplifier. Improvement in energy resolution by cooling the input FET using a small Peltier element has been discussed.
Periplasmic space in Salmonella typhimurium and Escherichia coli. (1977)

The volume of the periplasmic space in Escherichia coli and Salmonella typhimurium cells was measured. This space, in cells grown and collected under conditions routinely used in work with these bacteria, was shown to comprise from 20 to 40% of the total cell volume. Further studies were conducted to determine the osmotic relationships between the periplasm, the external milieu, and the cytoplasm. Results showed that there is a Donnan equilibrium between the periplasm and the extracellular fluid, and that the periplasm and cytoplasm are isoosmotic. In minimal salts medium, the osmotic strength of the cell interior was estimated to be approximately 300 mosM, with a net pressure of approximately 3.5 atm being applied to the cell wall. A corollary of these findings was that an electrical potential exists across the outer membrane. This potential was measured by determining the distributions of Na+ and Cl- between the periplasm and the cell exterior. The potential varied with the ionic strength of the medium; for cells in minimal salts medium it was approximately 30 mV, negative inside.
Tackling Cell Transplantation Anoikis: An Injectable, Shape Memory Cryogel Microcarrier Platform Material for Stem Cell and Neuronal Cell Growth (2015)

Highly macroporous semisynthetic cryogel microcarriers can be synthesized for culturing stem cells and neuronal type cells. Growth factors loaded to heparin-containing microcarriers show near zero-order release kinetics and cell-loaded microcarriers can be injected through a fine gauge cannula without negative effect on the cells. These carriers can be applied for cell transplantation applications.
Energy-quality scalable adaptive VLSI circuits and systems beyond approximate computing (2017)

In this paper, the concept of energy-quality (EQ) scalable systems is introduced and explored, as novel design dimension to scale down energy in integrated systems for the Internet of Things (IoT). EQ-scalable systems explicitly trade off energy and quality at different levels of abstraction (“vertically”), and sub-systems (“horizontally”), creating new opportunities to improve energy efficiency for a given task and expected “quality”. The concept of quality slack, a taxonomy of techniques to trade off energy and quality and a general EQ-scalable architecture are presented. The generality of the EQ-scaling concept is shown through several examples, ranging from logic to analog circuits, to memories and Analog-Digital Converters. Challenges, opportunities and expected energy gains are discussed to gain an understanding of the potential of the EQ-scalable integrated circuits and systems. As a result, EQ scalable systems are expected to substantially improve the energy efficiency of systems for IoT, compensating the limited energy gains that will be offered by technology and voltage scaling.
A Network-based Compute Reuse Architecture for IoT Applications (2021)

The tremendous advancements in the Internet of Things (IoT) increasingly involve computationally intensive services. These services often require more computation resources than can entirely be satisfied on local IoT devices. Cloud computing is traditionally used to provide unlimited computation resources at distant servers. However, such remote computation may not address the short-delay constraints that many of today's IoT applications require. Edge computing allows offloading computing close to end users to overcome computation and delay issues. Nonetheless, the edge servers may suffer from computing inefficiencies. Indeed, some IoT applications are invoked multiple times by multiple devices. These invocations are often used with the same or similar input data, which leads to the same computational output (results). Still, the edge server willfully executes all received redundant tasks. In this work, we investigate the use of the computation reuse concept at the edge server. We design a network-based computation reuse architecture for IoT applications. The architecture stores previously executed results and reuses them to satisfy newly arrived similar tasks instead of performing computation from scratch. By doing so, we eliminate redundant computation, optimize resource utilization, and decrease task completion time. We implemented the architecture and evaluated its performance both at the networking and application levels. From the networking perspective, we reach up to an 80\% reduction in task completion time and up to 60\% reduction in resource utilization. From the application perspective, we achieve up to 90\% computation correctness and accuracy.
Pharmacologic Inhibition of mTOR Improves Lapatinib Sensitivity in HER2-Overexpressing Breast Cancer Cells with Primary Trastuzumab Resistance (2012)

Lapatinib, a dual EGFR/HER2 kinase inhibitor, is approved for use in patients with trastuzumab-refractory HER2- overexpressing breast cancer. Increased PI3K signaling has been associated with resistance to trastuzumab, although its role in lapatinib resistance remains unclear. The purpose of the current study was to determine if PI3K/mTOR activity affects lapatinib sensitivity. Reduced sensitivity to lapatinib was associated with an inability of lapatinib to inhibit Akt and p70S6K phosphorylation. Transfection of constitutively active Akt reduced lapatinib sensitivity, while kinase-dead Akt increased sensitivity. Knockdown of 4EBP1 also increased lapatinib sensitivity, in contrast to p70S6K knockdown, which did not affect response to lapatinib. Pharmacologic inhibition of mTOR using rapamycin or ridaforolimus increased lapatinib sensitivity and reduced phospho-Akt levels in cells that showed poor response to single-agent lapatinib, including those transfected with hyperactive Akt. Finally, combination mTOR inhibition plus lapatinib resulted in synergistic inhibition of proliferation, reduced anchorage-independent growth, and reduced in vivo tumor growth of HER2- overexpressing breast cancer cells that have primary trastuzumab resistance. Our data suggest that PI3K/mTOR inhibition is critical for achieving optimal response to lapatinib. Collectively, these experiments support evaluation of lapatinib in combination with pharmacologic mTOR inhibition as a potential strategy for inhibiting growth of HER2-overexpressing breast cancers that show resistance to trastuzumab and poor response to lapatinib.
Properties of targeted preamplification in DNA and cDNA quantification (2015)

On the basis of our findings, we provide recommendations how to perform robust and highly accurate targeted preamplification in combination with qPCR or next-generation sequencing.

Damage assessment in composites by Lamb waves and wavelet coefficients (2003)

A wavelet technique was used in an active system for the damage detection of aerospace composites. The active system was based on the generation and reception of Lamb waves by embedded piezoceramic transducers. The wavelets were used to decompose the Lamb-wave response into wavelet coefficients. The decomposition performance was improved by utilizing more adapted wavelets, based on the recurrent waveforms of Lamb waves. The changes in the Lamb waves interacting with damage in the plate were successfully characterized by this wavelet technique, through the amplitude change of the wavelet coefficients. The wavelet technique also showed great sensitivity in detecting damage of small sizes. This technique was found to be straightforward for detection of impact damage and evaluation of the damage size.
Characterization of multiple Si∕SiO2 interfaces in silicon-on-insulator materials via second-harmonic generation (2004)

Charge generation, transport, and recombination processes in UNIBOND® silicon-on-insulator wafers are studied via an optical second-harmonic generation (SHG) technique. The electric fields at the interfaces vary with time due to charge trapping. The presence of a thin native oxide layer on the top Si film contributes significantly to the SH intensity due to the strong time-dependent electric field generated by electrons transported to the surface. For the thick buried oxide, the electric field is primarily due to carrier trapping at the interface, and it varies with time weakly. The SHG signals depend strongly on the externally applied electric field, which can differentiate the contribution of each interface to the total SH signal.
Adaptive Feedback Communications (1968)

A scheme for transmitting binary signals through a Rayleigh fading multipath medium is analyzed. The scheme envisions an adaptive receiver and a feedback channel. The feedback channel conveys information to the transmitter on the forward channel state learned at the receiver. The transmitter uses this information to modify transmission. Results that show the improvement in performance of the system under the assumptions of perfect receiver learning and noise-free feedback are presented. In this way, upper bounds on system performance are established.
Using metadata to deliver relevant and valuable content (2016)

Video content providers, from traditional broadcasters to Internet streaming platforms, face expanding consumption models and the challenge of responding to direct and immediate feedback from viewers. This evolution makes it necessary for content providers to deliver enriched, relevant and valuable content to the individuals consuming it. Metadata is the key to enabling this consumer-driven evolution and is used to enhance the viewing experience by providing support for such features as multiple languages and on screen graphics. As metadata advances, it enables content providers additional revenue opportunities through defined splice points signalling when local or targeted advertising may be inserted. It also provides video segment identifiers to block the distribution of content across unauthorized distribution channels and during blackout periods. This paper presents cutting edge technology that helps content provides insert and validate metadata whilst ensuring adherence to the standards. It discusses how content providers can best make the most of metadata to deliver relevant and enriched content to its consumers. It will describe available technology.
GPU-based NFA implementation for memory efficient high speed regular expression matching (2012)

Regular expression pattern matching is the foundation and core engine of many network functions, such as network intrusion detection, worm detection, traffic analysis, web applications and so on. DFA-based solutions suffer exponentially exploding state space and cannot be remedied without sacrificing matching speed. Given this scalability problem of DFA-based methods, there has been increasing interest in NFA-based methods for memory efficient regular expression matching. To achieve high matching speed using NFA, it requires potentially massive parallel processing, and hence represents an ideal programming task on Graphic Processor Unit (GPU). Based on in-depth understanding of NFA properties as well as GPU architecture, we propose effective methods for fitting NFAs into GPU architecture through proper data structure and parallel programming design, so that GPU's parallel processing power can be better utilized to achieve high speed regular expression matching. Experiment results demonstrate that, compared with the existing GPU-based NFA implementation method [9], our proposed methods can boost matching speed by 29~46 times, consistently yielding above 10Gbps matching speed on NVIDIA GTX-460 GPU. Meanwhile, our design only needs a small amount of memory space, growing exponentially more slowly than DFA size. These results make our design an effective solution for memory efficient high speed regular expression matching, and clearly demonstrate the power and potential of GPU as a platform for memory efficient high speed regular expression matching.
Creating large bandwidth line defects by embedding dielectric waveguides into photonic crystal slabs (2002)

We introduce a general designing procedure that allows us, for any given photonic crystal slab, to create an appropriate line defect structure that possesses single-mode bands with large bandwidth and low dispersion within the photonic band-gap region below the light line. This procedure involves designing a high index dielectric waveguide that is phase matched with the gap of the photonic crystal slab, and embedding the dielectric waveguide as a line defect into a crystal in a specific configuration that is free of edge states within the guiding bandwidth. As an example, we show a single mode line defect waveguide with a bandwidth approaching 13% of the center-band frequency, and with a linear dispersion relation throughout most of the bandwidth.
Allometry between length and cross‐sectional dimensions of the femur and tibia in <i>Homo sapiens sapiens</i> (1984)

Allometric equations relating length and cross-sectional geometric properties of the femur and tibia are generated using skeletal remains from three recent human population samples. Approximate isometry, or geometric similarity, is found both within and between samples. Cross-sectional areas scale to approximately length2, while second moments of area scale to approximately length4. It is shown that this is consistent with the maintenance of equivalent mechanical stress in long bones of different length under dynamic loadings in vivo. Other evidence indicates that bending and torsional loadings are more critical than axial loadings in the determination of lower limb bone cross-sectional dimensions.
