Chipless Sensing System Compliant With the Standard Radio Frequency Regulations (2019)

The aim of this paper is to develop a framework of a chipless wireless system for sensing in compliance with the standard international regulations. The proposed approach offers a solution to solve the main difficulty met for the deployment of chipless systems that require specific readers (based on non-standardized large frequency bands and specific signal waveforms). The possibility of interrogating chipless sensors in the regulated bands is demonstrated. The concept is introduced from several chipless sensor solutions, including specific sensors (here sensors for detecting temperature then motion), and the associated reader architecture built as a prototyping platform based on universal software radio peripheral (USRP).
Nanostructural Effects on Polymer and Water Dynamics in Cellulose Biocomposites: 2H and 13C NMR Relaxometry (2015)

Improved moisture stability is desired in cellulose biocomposites. In order to clarify nanostructural effects, a new approach is presented where water and polymer matrix mobilities are characterized separately. Nanocomposites from cellulose nanofibers (CNF) in the xyloglucan (XG) biopolymer matrix are investigated at different hydration states. Films of XG, CNF, and CNF/XG composites are subjected to detailed (2)H and (13)C NMR relaxation studies. Since the (2)H NMR signal arises from heavy water and the (13)C signal from the polysaccharides, molecular water and polymer dynamics is for the first time investigated separately. In the neat components, (2)H transverse relaxation (T2) data are consistent with water clustering at the CNF fibril surfaces, but bulk spread of moisture in XG. The new method results in a description of water interaction with the nanoscale phases. At low hydration, water molecules at the CNF/XG interface exhibit higher water mobility than in neat CNF or XG, due to locally high water concentration. At the same time, CNF-associated interphase segments of XG show slower NMR-dynamics than that in neat XG.
Expressing adverbial relations in clause linkage with converbs: definitional and typological considerations (2016)

Converbs are often defined as adverbial verb forms (e.g. Haspelmath 1995) and are a primary means of encoding adverbial relations in clause linkage in many languages around the world. However, before making progress in understanding this relationship, several definitional issues must be addressed, and typological variation must be considered. The topics in this talk are informed by a growing typologically-balanced sample of over 325 languages, based on the methodology of the World Atlas of Language Structures (Haspelmath et al. 2005). Despite much discussion, no representative cross-linguistic survey of converbs has been published, and different claims in the literature are often informed/biased by the data provided by the language or region in question. This research is an attempt to rectify that by introducing topics that must be considered before any general conclusions about converbs can be drawn, in order to build a foundation of typological variation from which adverbial clause linkage can be studied.
NDE TECHNIQUES FOR DETECTING GROUT DEFECTS IN CABLE STAYS. FINAL REPORT (1993)

Problems with corrosion of steel strands in grouted bridge cable stays have raised concern about the integrity of the grout layer protecting the strands. Bleed water that may accumulate in the grout layer if voids or bubbles are trapped during the grouting process can lead to corrosion of the cables. This research study was undertaken to evaluate various nondestructive evaluation (NDE) methods for inspection of this grout layer. Methods which were studied include ultrasonics, film radiography, computed tomography (CT), and neutron radiography. The feasibility of using computed tomography for inspection of the grout layer has been demonstrated. Voids as small as 0.04 in. (1 mm) in diameter were identified in both the annular region of grout and inside the steel cable bundle. Although some of these voids were manufactured, many of those found were a result of the grouting operation during fabrication of the specimens, an observation which lends urgency to the need for an inspection system. Laboratory experiments were conducted with a prototype ultrasonic inspection unit which utilizes two rolling contact probes with 500 kHz transducers. A digital signal subtraction technique was found to be particularly useful in analyzing the received signals. The ultrasonic system was successful in identifying the location of defects, but information regarding the size and content of the defects was inconclusive. Three distinct regions exist along the cable which will most likely require different inspection schemes. It is envisioned that the main section of cable will be inspected by one technique, possibly ultrasonics, while the lower regions of cable, where extra layers are added for fire and crash protection, will require a radiographic technique. The third region, which includes the saddles and anchorages, will likely require a third inspection technique, such as a portable linear accelerator.

Cell-penetrating peptides enhance peptide vaccine accumulation and persistence in lymph nodes to drive immunogenicity (2022)

Peptide-based cancer vaccines are widely investigated in the clinic but exhibit modest immunogenicity. One approach that has been explored to enhance peptide vaccine potency is covalent conjugation of antigens with cell-penetrating peptides (CPPs), linear cationic and amphiphilic peptide sequences designed to promote intracellular delivery of associated cargos. Antigen-CPPs have been reported to exhibit enhanced immunogenicity compared to free peptides, but their mechanisms of action in vivo are poorly understood. We tested eight previously described CPPs conjugated to antigens from multiple syngeneic murine tumor models and found that linkage to CPPs enhanced peptide vaccine potency in vivo by as much as 25-fold. Linkage of antigens to CPPs did not impact dendritic cell activation but did promote uptake of linked antigens by dendritic cells both in vitro and in vivo. However, T cell priming in vivo required <i>Batf3</i>-dependent dendritic cells, suggesting that antigens delivered by CPP peptides were predominantly presented via the process of cross-presentation and not through CPP-mediated cytosolic delivery of peptide to the classical MHC class I antigen processing pathway. Unexpectedly, we observed that many CPPs significantly enhanced antigen accumulation in draining lymph nodes. This effect was associated with the ability of CPPs to bind to lymph-trafficking lipoproteins and protection of CPP-antigens from proteolytic degradation in serum. These two effects resulted in prolonged presentation of CPP-peptides in draining lymph nodes, leading to robust T cell priming and expansion. Thus, CPPs can act through multiple unappreciated mechanisms to enhance T cell priming that can be exploited for cancer vaccines with enhanced potency.
Issues in Humanoid Audition and Sound Source Localization by Active Audition. (2003)

In this paper, we present an active audition system which is implemented on the humanoid robot "SIG the humanoid". The audition system for highly intelligent humanoids localizes sound sources and recognizes auditory events in the auditory scene. Active audition reported in this paper enables SIG to track sources by integrating audition, vision, and motor movements. Given the multiple sound sources in the auditory scene, SIG actively moves its head to improve localization by aligning microphones orthogonal to the sound source and by capturing the possible sound sources by vision. However, such an active head movement inevitably creates motor noises.The system adaptively cancels motor noises using motor control signals and the cover acoustics. The experimental result demonstrates that active audition by integration of audition, vision, and motor control attains sound source tracking in variety of conditions.onditions.
Shape Matching Using Multiscale Integral Invariants (2014)

We present a shape descriptor based on integral kernels. Shape is represented in an implicit form and it is characterized by a series of isotropic kernels that provide desirable invariance properties. The shape features are characterized at multiple scales which form a signature that is a compact description of shape over a range of scales. The shape signature is designed to be invariant with respect to group transformations which include translation, rotation, scaling, and reflection. In addition, the integral kernels that characterize local shape geometry enable the shape signature to be robust with respect to undesirable perturbations while retaining discriminative power. Use of our shape signature is demonstrated for shape matching based on a number of synthetic and real examples.

Cell Kinetic Studies of Prostatic Cancer: Adjuvant Therapy in Animal Models (1977)

Cell kinetic studies have been applied to the rat prostatic cancer R-3327-AT. This transplantable anaplastic tumor has a rapid growth rate and doubles its volume every 2.17 days. Cell kinetic considerations have been used to design a therapeutic approach which is capable of curing animals carrying this tumor, or providing long periods of complete remission. This treatment approach involves chemotherapy followed by surgery and immuno-stimulation with pyran copolymer. Such adjuvant tumor therapy is most effective against a small tumor load. The application of cell kinetic considerations to the control of human prostatic cancer is discussed.
Compounding a High-Permittivity Thermoplastic Material and Its Applicability in Manufacturing of Microwave Photonic Crystals (2022)

Additive Manufacturing (AM) techniques allow the production of complex geometries unattainable through other traditional technologies. This advantage lends itself well to rapidly iterating and improving upon the design of microwave photonic crystals, which are structures with intricate, repeating features. The issue tackled by this work involves compounding a high-permittivity material that can be used to produce 3D microwave photonic structures using polymer extrusion-based AM techniques. This material was acrylonitrile butadiene styrene (ABS)-based and used barium titanate (BaTiO<sub>3</sub>) ceramic as the high-permittivity component of the composite and involved the use of a surfactant and a plasticizer to facilitate processing. Initial small amounts of the material were compounded using an internal batch mixer and studied using polymer thermal analysis techniques, such as thermogravimetric analysis, rheometry, and differential scanning calorimetry to determine the proper processing conditions. The production of the material was then scaled up using a twin-screw extruder system, producing homogeneous pellets. Finally, the thermoplastic composite was used with a screw-based, material extrusion additive manufacturing technique to produce a slab for measuring the relative permittivity of the material, as well as a preliminary 3D photonic crystal. The real part of the permittivity was measured to be 12.85 (loss tangent = 0.046) in the range of 10 to 12 GHz, representing the highest permittivity ever demonstrated for a thermoplastic AM composite at microwave frequencies.
Privacy for IoT: Involuntary privacy enablement for smart energy systems (2015)

Smart meter, the important component of smart energy management systems invites intended or unintended, possibly dangerous privacy breaching activities, like in-house activity detection. With the emergence of Non-Intrusive Load Monitoring (NILM), privacy preservation of smart meter data becomes very important for an individual. Emerging solution provides privacy breach minimization by supervised learning through training that incurs higher capex and opex. IoT systems do not consist of human-in-loop. So, involuntary approach of privacy preservation is to be employed. In this paper, we propose a novel solution for addressing the problem of involuntary privacy breaching risk minimization in smart energy management systems. Our proposed solution `Dynamic Privacy Analyzer' scheme is an attempt towards achieving a unique privacy metric that is derived from fundamental principles like robust statistics and information theory. We analyze the performance of our scheme with large set of publicly available real smart meter datasets and evaluate optimality criteria like utility-privacy trade-off. Efficacy of our proposed scheme is demonstrated by minimizing the capability of privacy intruders like NILM. To the best of our knowledge, for the first time the involuntary privacy-aware scheme tailored for IoT system is proposed. Our proposed scheme is generic enough to suit in other IoT applications.
SUBNANOSECOND HIGH-POWER PERFORMANCE OF A BISTABLE OPTICALLY CONTROLLED GaAs SWITCH (1993)

Abstract : Recent subnanosecond-opening results of the Bistable Optically controlled Semiconductor Switch (BOSS) are presented. The processes of persistent photoconductivity followed by photoquenching have been demonstrated in copper-compensated, silicon-doped, semi-insulating (GaAs:Si:Cu). These processes allow a switch to be developed that can be closed by the application of one laser pulse (Iambda= 1.06 pm) and opened by the application of a second laser pulse with a wavelength equal to twice that of the first laser. The opening phase is a two-step process which relies initially on the absorption of the 2.13-(mu)m laser and finally on the recombination of electrons in the conduction band with holes in the valence band. The second step requires a sufficient concentration of recombination centers in the material for this process to occur in the subnanosecond regime. This report discusses the effects of 1-MeV neutron irradiation on the BOSS material for the purpose of recombination center generation. Initial experiments indicated a reduction of the recombination time from several nanoseconds down to about 180 ps. Both experimental and theoretical results are presented.
Impact of VUV photons on SiO2 and organosilicate low-k dielectrics: General behavior, practical applications, and atomic models (2019)

This paper presents an in-depth overview of the application and impact of UV/VUV light in advanced interconnect technology. UV light application in BEOL historically was mainly motivated by the need to remove organic porogen and generate porosity in organosilicate (OSG) low-k films. Porosity lowered the film's dielectric constant, k, which enables one to reduce the interconnect wiring capacitance contribution to the RC signal delay in integrated circuits. The UV-based low-k film curing (λ &amp;gt; 200 nm) proved superior to thermal annealing and electron beam curing. UV and VUV light also play a significant role in plasma-induced damage to pSiCOH. VUV light with λ &amp;lt; 190–200 nm is able to break Si-CH3 bonds and to make low-k materials hydrophilic. The following moisture adsorption degrades the low-k properties and reliability. This fact motivated research into the mechanisms of UV/VUV photon interactions in pSiCOH films and in other materials used in BEOL nanofabrication. Today, the mechanisms of UV/VUV photon interactions with pSiCOH and other films used in interconnect fabrication are fairly well understood after nearly two decades of research. This understanding has allowed engineers to both control the damaging effects of photons and utilize the UV light for material engineering and nanofabrication processes. Some UV-based technological solutions, such as low-k curing and UV-induced stress engineering, have already been widely adopted for high volume manufacturing. Nevertheless, the challenges in nanoscaling technology may promote more widespread adoption of photon-assisted processing. We hope that fundamental insights and prospected applications described in this article will help the reader to find the optimal way in this wide and rapidly developing technology area.
Intra-operative Hemostasis of Punctured Femoral Artery Using HIFU: A Survival Study (2005)

The objective was to investigate the long‐term efficacy of hemostasis and healing of arteries after HIFU application. The femoral arteries of 22 adult rabbits were surgically exposed. Fifteen arteries were punctured with a needle and treated with HIFU, and 7 arteries were sham‐treated (no puncture or HIFU was applied). The tip of the HIFU applicator was positioned on the bleeding site, and HIFU energy was applied until hemostasis was achieved. The focal intensity was approximately 3,000 W/cm2, at the resonant frequency of 9.6 MHz. Serial ultrasound images, blood and tissue samples were collected immediately and on days 1, 3, 7, 14, 28, and 60 after the treatment. Eleven of the arteries were patent after the treatment, and four arteries were occluded, as confirmed using Doppler imaging. One of the occluded arteries reopened at day 14. HIFU exposure time to achieve hemostasis was 27 ±17 seconds for patent arteries and 101±38 seconds for the occluded arteries. The blood flow velocities were not statistically different between HIFU‐treated patent vessels and sham‐treated vessels. The tunica adventitia and media, disrupted and coagulated immediately after the treatment, recovered to normal appearance within 28 days, with localized thinning of the tunica media observed up to day 60. Neo‐intimal hyperplasia was observed in the arteries at days 14 and 28. HIFU produced an effective and long‐term (up to 60 days) hemostasis of injured femoral arteries while preserving a normal blood flow and vessel wall structure in the majority of vessels.
Scope and Mechanism of the Intermolecular Addition of Aromatic Aldehydes to Olefins Catalyzed by Rh(I) Olefin Complexes (2007)

Rhodium (I) bis-olefin complexes Cp*Rh(VTMS)(2) and CpRh(VTMS)(2) (Cp* = C(5)Me(5), Cp = C(5)Me(4)CF(3), VTMS = vinyl trimethylsilane) were found to catalyze the addition of aromatic aldehydes to olefins to form ketones. Use of the more electron-deficient catalyst CpRh(VTMS)(2) results in faster reaction rates, better selectivity for linear ketone products from alpha-olefins, and broader reaction scope. NMR studies of the hydroacylation of vinyltrimethylsilane showed that the starting Rh(I) bis-olefin complexes and the corresponding Cp*/Rh(CH(2)CH(2)SiMe(3))(CO)(Ar) complexes were catalyst resting states, with an equilibrium established between them prior to turnover. Mechanistic studies suggested that CpRh(VTMS)(2) displayed a faster turnover frequency (relative to Cp*Rh(VTMS)(2)) because of an increase in the rate of reductive elimination, the turnover-limiting step, from the more electron-deficient metal center of CpRh(VTMS)(2). Reaction of Cp*/Rh(CH(2)CH(2)SiMe(3))(CO)(Ar) with PMe(3) yields acyl complexes Cp*/Rh[C(O)CH(2)CH(2)SiMe(3)](PMe(3))(Ar); measured first-order rates of reductive elimination of ketone from these Rh(III) complexes established that the Cp ligand accelerates this process relative to the Cp* ligand.
Phospholipase D2 Directly Interacts with Aldolase via Its PH Domain (2002)

Mammalian phospholipase D (PLD) has been implicated in the cellular signal transduction pathways leading to diverse physiological events and known to be regulated by many cellular factors. To identify the proteins that interact with PLD, we performed a protein overlay assay with fractions obtained from the sequential column chromatographic separation of rat brain cytosol using purified PLD2 as a probe. A protein of molecular mass 40 kDa, which was detected by anti-PLD antibody with overlaying of the purified PLD2, is shown to be aldolase C by peptide-mass fingerprinting with matrix-assisted laser desorption/ionization-time-of flight mass spectrometry (MALDI-TOF-MS). Aldolase A also showed similar binding properties as aldolase C and was co-immunoprecipitated with PLD2 in COS-7 cells overexpressing PLD2 and aldolase A. The PH domain corresponding to amino acids 201-310 of PLD2 was necessary for the interaction observed in vitro, and aldolase A was found to interact with the PH domain of PLD2 specifically, but not with other PH domains. PLD2 activity was inhibited by the presence of purified aldolase A in a dose-dependent manner, and the inhibition by 50% was observed by the addition of less than micromolar aldolase A. Moreover, the inclusion of the aldolase metabolites fructose 1,6-bisphosphate (F-1,6-P) or glyceraldehyde 3-phosphate (G-3-P) resulted in an enhanced interaction between PLD2 and aldolase A with a concomitant increase in the potential ability of aldolase A to inhibit PLD2, which suggests the existence of a possible regulation of the interaction by the change of intracellular concentrations of glycolytic metabolites.
Bipolar disorder and its relation to major psychiatric disorders: a family‐based study in the Swedish population (2014)

The high familial risks provide evidence that genetic factors play an important role in the etiology of BPD, and the shared genetic determinants suggest pleiotropic effects across different psychiatric disorders. Results also indicate that BPD is in both the mood and psychotic spectra, but possibly more closely related to mood disorders.
Enhanced mechanical and gas barrier performance of plasticized cellulose nanofibril films (2022)

Abstract Cellulose nanofibrils (CNF) are mixed with plasticizers; sorbitol and glycerol, through high-pressure homogenization to prepare multifunctional biohybrid films. The resulting plasticized films obtained after solvent evaporation are strong, flexible and demonstrate superior toughness and optical transparency. The oxygen barrier properties of the biohybrid films outperform commercial packaging materials. The sorbitol-plasticized CNF films possess excellent oxygen barrier properties, 0.34 cm 3 ·μm/m 2 ·day·kPa at 50 % relative humidity, while significantly enhancing the toughness and fracture strength of the films. CNF films plasticized by 20 wt.% of sorbitol and glycerol could before rupture, be strained to about 9 % and 12 %, respectively. The toughness of the plasticized films increased by ca. 300 % compared to the pristine CNF film. Furthermore, the water vapor barrier properties of the biohybrid films were also preserved by the addition of sorbitol. CNF films plasticized with sorbitol was demonstrated to simultaneously enhance fracture toughness, work of fracture, softening behavior while preserving gas barrier properties. Highly favorable thermomechanical characteristics were found with CNF/sorbitol combinations and motivate further work on this material system, for instance as a thermoformable matrix in biocomposite materials. The unique combination of excellent oxygen barrier behavior, formability and optical transparency suggest the potential of these CNF-based films as an alternative in flexible packaging of oxygen sensitive devices like thin-film transistors or organic light-emitting diode displays, gas storage applications and as barrier coatings/laminations in packaging applications, including free-standing films as aluminium-replacement in liquid board and primary packaging, as replacement for polyethylene (PE) in wrapping paper, e. g. sweats and confectionary.
