Cancellation of Correlation Side-Peaks for Unambiguous BOC Signal Tracking (2012)

Based on a combination of the sub-correlation functions composing the autocorrelation of the binary offset carrier (BOC), we propose a novel cancellation scheme of correlation side-peaks to solve the ambiguity problem in the BOC signal tracking. The proposed scheme is applicable to both generic sine- and cosine-phased BOC signals without requiring any auxiliary signal in the receiver. Avoiding the ambiguity problem, the proposed scheme is confirmed from numerical results to provide a better tracking accuracy than the conventional schemes.
Digital Forensic Techniques for Graphic Data (2007)

With rapid development of hardware devices and software programs, a large amount of graphic data has been brought to or generated in digital domain, and become increasingly more widely used in our everyday life. Due to the ease of editing and distributing graphic data in the digital domain, protecting graphic data from such fraudulent operations as malicious tampering and unauthorized copying is becoming a major concern. The primary motivation of this dissertation research is to develop novel forensic techniques for digital graphic data to facilitate its proper distribution, authentication, and usage. We investigate two complementary mechanisms for performing forensic analysis on graphic data, namely, the extrinsic and intrinsic approaches. In the extrinsic approaches, we seamlessly embed into graphic data extrinsic watermarks/fingerprints, which shall later be extracted for verifying authenticityor tracing leak of the graphic data. By utilizing such extrinsic techniques via data embedding, we have studied robust digital fingerprinting for curve-based graphics such as topographic maps and drawings, in which a unique ID referred to as a digital fingerprint is robustly embedded for tracing traitors.

Unprecedented Chiral Molecular Recognition in a C3-Symmetric Environment (2002)

The enantiomeric recognition of alpha-chiral primary ammonium ions has been studied with benzene-based tripodal tris(oxazoline) receptors. Contrary to the literature and our expectation, a good level of chiral discrimination is observed with one of the tripodal receptors, which provides a C3-symmetric chiral environment on guest binding. The chiral discrimination has been found to be general in the case of alpha-aryl substituted guests, suggesting pi-pi interactions as an important factor. This result raises a question with respect to the origin of the chiral discrimination since little steric or electronic difference is expected between the diastereomeric inclusion complexes. Binding studies by NMR titration and isothermal titration calorimetry show that the chiral discrimination results from the different thermodynamic stabilities between the diastereomeric complexes and that the host-guest complex formation is driven by favorable enthalpy changes with a minor negative contribution by entropy changes. The X-ray crystal structures for both of the diastereomeric inclusion complexes are resolved, which unambiguously show the binding mode and provide clues on the origin of the chiral discrimination. Bond angle analyses indicate that the minor complex experiences a larger steric strain, which is discernible when it is viewed from "three-body" interactions between the host and the guest. The guest and oxazoline phenyl rings are well stacked, indicating interplay of the pi-pi interactions. The pi-pi interactions are believed to stabilize host-guest complexes, thereby endowing the highly flexible receptors with a substantial enantio-discrimination.
Achieving High Porosity in Scaffold Building Using Electrohydrodynamic Jetting 3D Printing (2014)

Electrohydrodynamic Jetting (E-Jetting) printing is a promising microfabrication technology for its unique capability of generating and controlling fine fibers at nanometer/micrometer level. Its capability of building highly oriented scaffold makes it superior for some bio-medical applications. The porosity of E-jeted scaffold is essential in order to provide an environment mimicking the functional cells living environment. This paper analyzes fiber diameter and fiber adjacent gap, and proposes an ideal process to build scaffolds with controllable porosity and precisely oriented fibers.
Selective and high-rate CO2 electroreduction by metal-doped covalent triazine frameworks: a computational and experimental hybrid approach (2022)

The electrochemical CO<sub>2</sub> reduction reaction (CO<sub>2</sub>RR) has attracted intensive attention as a technology to achieve a carbon-neutral society. The use of gas diffusion electrodes (GDEs) enables the realization of high-rate CO<sub>2</sub>RRs, which is one of the critical requirements for social implementation. Although both a high reaction rate and good selectivity are simultaneously required for electrocatalysts on GDEs, no systematic study of the relationship among active metal centers in electrocatalysts, reaction rate, and selectivity under high-rate CO<sub>2</sub>RR conditions has been reported. In the present study, we employed various metal-doped covalent triazine frameworks (M-CTFs) as platforms for CO<sub>2</sub> reduction reaction (CO<sub>2</sub>RR) electrocatalysts on GDEs and systematically investigated them to deduce sophisticated design principles using a combined computational and experimental approach. The Ni-CTF showed both high selectivity (faradaic efficiency (FE) > 98% at -0.5 to -0.9 V <i>vs.</i> reversible hydrogen electrode) and a high reaction rate (current density < -200 mA cm<sup>-2</sup>) for CO production. By contrast, the Sn-CTF exhibited selective formic acid production, and the FE and partial current density reached 85% and 150 mA cm<sup>-2</sup>, respectively. These results for the CO<sub>2</sub>RR activity and selectivity at high current density with respect to metal centers correspond well with predictions based on first-principles calculations. This work is the first demonstration of a clear relationship between the computational adsorption energy of intermediates depending on metal species and the experimental high-rate gaseous CO<sub>2</sub>RR.
Klassifikation leicht verwundbarer Verkehrsteilnehmer mit hochauflösendem Automobilradar (2017)

Der Schutz von Fußgängern und Fahrrad­fahrern rückt verstärkt in den Fokus zukünftiger voraus­schauender Fahrer­assistenz- und Fahr­sicherheits­systeme. Insbesondere Situationen in denen Fußgänger eine Sonder­stellung im Straßenverkehr einnehmen, wie beispiels­weise beim Ausfahren aus Kreis­verkehren, an Fußgänger­über­wegen oder in verkehrs­beruhigten Bereichen, erfordern die Erkennung objekt­spezi­fischer Informationen und eine darauf basierende robuste Objekt­klassi­fikation. Im Hinblick auf zukünftige Heraus­forderungen wird in der vorliegenden Arbeit ein innovativer Ansatz zur Klassifikation von Fußgängern, Fahrrad­fahrern und Personen­kraftwagen vorgestellt, welcher auf der Extraktion objekt­spezifischer Merk­male aus mehr­dimensionalen Detektions­clustern eines hoch­auflösenden automobilen Radar­sensors basiert. Zur Bildung geeigneter Detektions­cluster wurden durch Integration eines Fußgänger­bewegungs­modells in eine Radar­system­simulation Auflösungs­anforder­ungen abgeleitet, anhand welcher ein proto­typischer hoch­auflösender Radar­sensor spezifiziert und aufgebaut werden konnte. Die durch eine weiterhin entwickelte Signal­verarbeitungs­kette gebildeten Detektions­cluster ermöglichen die Extraktion objekt­spezifischer Merkmale wie der Form oder der Ausdehnung von Objekten sowie der Schritt­frequenz von Fußgängern. Unter Verwendung dieser Merkmale wird im Mittel eine korrekte Zuordnung zu den Klassen Fußgänger, Fahrrad­fahrer und PKW von 97 % aller nicht als unbekannt klassifizierten Detektions­cluster erreicht.
Production and Characterization of a Camelid Single Domain Antibody–Urease Enzyme Conjugate for the Treatment of Cancer (2015)

A novel immunoconjugate (L-DOS47) was developed and characterized as a therapeutic agent for tumors expressing CEACAM6. The single domain antibody AFAIKL2, which targets CEACAM6, was expressed in the Escherichia coli BL21 (DE3) pT7-7 system. High purity urease (HPU) was extracted and purified from Jack bean meal. AFAIKL2 was activated using N-succinimidyl [4-iodoacetyl] aminobenzoate (SIAB) as the cross-linker and then conjugated to urease. The activation and conjugation reactions were controlled by altering pH. Under these conditions, the material ratio achieved conjugation ratios of 8-11 antibodies per urease molecule, the residual free urease content was practically negligible (<2%), and high purity (>95%) L-DOS47 conjugate was produced using only ultradiafiltration to remove unreacted antibody and hydrolyzed cross-linker. L-DOS47 was characterized by a panel of analytical techniques including SEC, IEC, Western blot, ELISA, and LC-MS(E) peptide mapping. As the antibody-urease conjugate ratio increased, a higher binding signal was observed. The specificity and cytotoxicity of L-DOS47 was confirmed by screening in four cell lines (BxPC-3, A549, MCF7, and CEACAM6-transfected H23). BxPC-3, a CEACAM6-expressing cell line was found to be most susceptible to L-DOS47. L-DOS47 is being investigated as a potential therapeutic agent in human phase I clinical studies for nonsmall cell lung cancer.
Multiplexing and demultiplexing using an AlGaAs nonlinear directional coupler (1995)

There has been a considerable amount of interest in utilising the nonresonant, third order, nonlinearity of optically transparent materials to implement all-optical switching and modulation operations. Such all-optical devices have considerable potential due to the instantaneous nature of the Kerr nonlinearity which makes possible ultrafast switching devices, which in turn would increase the usable bandwidth of optical fibres. In particular, devices formed in the AlGaAs material system have been shown to have several advantages, namely; they have a relatively large nonlinear coefficient, low propagation losses and can be operated in the 1.55 mu m spectral region. The resulting devices are compact and resistant to environmental perturbations. To date several individual components have been demonstrated: the nonlinear directional coupler (NLDC), the nonlinear Mach-Zehnder interferometer and the X-junction. In order to be of practical interest the more complex functions of multiplexing and demultiplexing need to be demonstrated. These operations involve both a control and a signal pulse. In the implementations discussed a strong control pulse, with either a different polarisation, or wavelength, is used to modulate a weak signal pulse. This corresponds to a strong local pump source adding, or dropping, data from a data stream.
Due domande sui limiti alla revisione costituzionale (2012)

When providing nursing services to inpatients with recurrent breast cancer, people must recognize there is a notable difference between individual patients' contextual conditions and interactive strategies. Henceforth, proper cognitive nursing must be provided which encourages patients to maintain a strong will to overcome the many hardships of treatment as well as physical nursing, such as management of side effects caused by chemotherapy.
Dynamics of Solid Lubrication as Observed by Optical Microscopy (1978)

A bench metallograph was converted into a “micro contact imager” by the addition of a tribometer employing a steel ball in sliding contact with a glass disk. The sliding contact was viewed in real time by means of projection microscope optics. The dynamics of abrasive particles and of solid lubricant particles within the contact were observed in detail. The contact was characterized by a constantly changing pattern of elastic strain with the passage of surface discontinuities and solid particles. Abrasive particles fragmented upon entering the contact, embedded in one surface and scratched the other; in contrast, the solid lubricant particles flowed plastically into thin films. The rheological behavior of the lubricating solids gave every appearance of a paste-like consistency within the Hertzian contact.
Focused ultrasound: an effective technique for unleashing the power of immunotherapy in the tumor microenvironment? (2015)

The tumor microenvironment presents significant barriers to the infiltration of anti-tumor immune effector cells as well as to the delivery of cancer therapeutics. In part, physical parameters such as high interstitial pressure, defective vascular elements and abnormally dense stromal elements contribute significantly to poor uptake of immune cells. However, growing evidence also shows that tumor-cells can produce inflammatory cytokines as well as express certain surface receptors that drive both the accumulation of immunosuppressive cells as well as block the activation of antigen-specific immune effector cells, such as CD8+ T cells, which are able to traverse the physical barriers to the interior of tumors.
SYNTHESEN VON ARYLTHIOETHERN DURCH RADIKALISCHE ADDITION VON ARYLMERCAPTANEN AN ARYLETHINVERBINDUNGEN (1988)

Abstract This paper describes the radical addition of mercaptanes to arylethins, which leads to two different products. The monoaddition yields enolthioether,1,2,3 which show a special cis and trans isomer ratio. A second addition of a mercaptane molecule to the monoadduct leads to an acetal-like dimercaptoether.4 By radical addition of mercaptobenzene to ethinylbenzene, both products were observed.3 The reactions between ethinylbenzene and 1,3-di-mercaptobenzene as well as between mercaptobenzene and 1,4-diethinylbenzene gave the monoaddition products only, the second addition could not be observed. The same behaviour shows the system of 1,4-diethinyl-benzene and 2-mercaptonaphthaline. The composition of the compounds and their cis-trans ratio were determined by n.m.r. and i.r. techniques, as well as by mass spectroscopy and elemental analysis. Die radikalische Addition von Mercaptanen an Arylethine kann zu zwei verschiedenen Verbindungen führen. Bei der Monoaddition entstehen Enolthioether,1,2,3 welche cis-trans-Isomerie aufweisen. Wiederholt sich der Anlagerungsschritt, so erhält man Mercaptale.4 Durch radikalische Addition von Mercaptobenzol an Phenylethin sind prinzipiell beide Produkte herstellbar.3 Im Gegensatz dazu wird bei der Addition von Phenylethin an 1,3-Dimercaptobenzol bzw. bei der Addition von Mercaptobenzol an 1,4-Diethinylbenzol jeweils nur das Monoadditionsprodukt erhalten. Ganz ähnlich verhält sich auch das System. 1,4-Diethinylbenzol und 2-Mercaptonaphthalin. Die entstehenden Verbindungen wurden mit den üblichen analytischen Methoden eindeutig charak-terisiert. Speziell die 1H-NMR-Spektroskopie gestattete es auch die cis-trans-Isometrie der entstehenden Enolether näher zu untersuchen.

Development of Perovskite-Type Materials for Thermoelectric Application (2018)

Oxide perovskite materials have a long history of being investigated for thermoelectric applications. Compared to the state-of-the-art tin and lead chalcogenides, these perovskite compounds have advantages of low toxicity, eco-friendliness, and high elemental abundance. However, because of low electrical conductivity and high thermal conductivity, the total thermoelectric performance of oxide perovskites is relatively poor. Variety of methods were used to enhance the TE properties of oxide perovskite materials, such as doping, inducing oxygen vacancy, embedding crystal imperfection, and so on. Recently, hybrid perovskite materials started to draw attention for thermoelectric application. Due to the low thermal conductivity and high Seebeck coefficient feature of hybrid perovskites materials, they can be promising thermoelectric materials and hold the potential for the application of wearable energy generators and cooling devices. This mini-review will build a bridge between oxide perovskites and burgeoning hybrid halide perovskites in the research of thermoelectric properties with an aim to further enhance the relevant performance of perovskite-type materials.

Personalized acoustic modeling by weakly supervised multi-task deep learning using acoustic tokens discovered from unlabeled data (2017)

It is well known that recognizers personalized to each user are much more effective than user-independent recognizers. With the popularity of smartphones today, although it is not difficult to collect a large set of audio data for each user, it is difficult to transcribe it. However, it is now possible to automatically discover acoustic tokens from unlabeled personal data in an unsupervised way. We therefore propose a multi-task deep learning framework called a phoneme-token deep neural network (PTDNN), jointly trained from unsupervised acoustic tokens discovered from unlabeled data and very limited transcribed data for personalized acoustic modeling. We term this scenario “weakly supervised”. The underlying intuition is that the high degree of similarity between the HMM states of acoustic token models and phoneme models may help them learn from each other in this multi-task learning framework. Initial experiments performed over a personalized audio data set recorded from Facebook posts demonstrated that very good improvements can be achieved in both frame accuracy and word accuracy over popularly-considered baselines such as fDLR, speaker code and lightly supervised adaptation. This approach complements existing speaker adaptation approaches and can be used jointly with such techniques to yield improved results.
Staphylococcus aureus Peptide Methionine Sulfoxide Reductases Protect from Human Whole-Blood Killing (2021)

The generation of oxidative stress is a host strategy used to control Staphylococcus aureus infections. Sulfur-containing amino acids, cysteine and methionine, are particularly susceptible to oxidation because of the inherent reactivity of sulfur. Due to the constant threat of protein oxidation, many systems evolved to protect S. aureus from protein oxidation or to repair protein oxidation after it occurs. The S. aureus peptide methionine sulfoxide reductase (Msr) system reduces methionine sulfoxide to methionine. Staphylococci have four Msr enzymes, which all perform this reaction. Deleting all four <i>msr</i> genes in USA300 LAC (Δ<i>msr</i>) sensitizes S. aureus to hypochlorous acid (HOCl) killing; however, the Δ<i>msr</i> strain does not exhibit increased sensitivity to H<sub>2</sub>O<sub>2</sub> stress or superoxide anion stress generated by paraquat or pyocyanin. Consistent with increased susceptibility to HOCl killing, the Δ<i>msr</i> strain is slower to recover following coculture with both murine and human neutrophils than USA300 wild type. The Δ<i>msr</i> strain is attenuated for dissemination to the spleen following murine intraperitoneal infection and exhibits reduced bacterial burdens in a murine skin infection model. Notably, no differences in bacterial burdens were observed in any organ following murine intravenous infection. Consistent with these observations, USA300 wild-type and Δ<i>msr</i> strains have similar survival phenotypes when incubated with murine whole blood. However, the Δ<i>msr</i> strain is killed more efficiently by human whole blood. These findings indicate that species-specific immune cell composition of the blood may influence the importance of Msr enzymes during S. aureus infection of the human host.
A Prospective Analysis of Prognostic Factors in Patients With Spinal Metastases (2010)

Lower score on performance status, the existence of organ metastases, and primary cancer of the lung and the kidney were significantly associated with poor survival. The revised Tokuhashi score was found to be very useful to predict survival regardless of the treatment pathway. In most patients, actual survival matched their predicted survival.

Improved radar tracking using a multipath model: maximum likelihood compared with eigenvector analysis (1994)

The performance of the MUSIC algorithm and many other superresolution methods degrades severely with the highly correlated multipath signals encountered in radar low-angle tracking. The paper presents a new eigenvector-based method in which the search vector is replaced by a deterministic specular multipath model. The performance is then compared with that of maximum likelihood using the same model and the well known MUSIC algorithm using spatial smoothing. Simulations and experiments at X-band indicate that the use of a specular model combined with an array radar having frequency agility gives much more accurate tracking than the conventional approaches. The experiments were conducted at Sylt (North Sea), Germany, using corner reflectors mounted on poles inserted in the sea bed; sea conditions varied from sea-state one to five.
Near-field scattering by a sparse discrete random medium: microphysical radiative transfer theory (2014)

The discussion in the preceding chapter was limited to the far field of a random particulate volume comprising a moderate number of particles. However, one is often interested in the near field in order to compute the energy budget of a volume element of a DRM rather than of the entire DRM. Furthermore, in the majority of actual applications the detector of light is located in the near zone of the entire DRM, including the cases of being inside the particulate volume. Although numerically exact solvers of the MMEs such as the MSM (Section 16.1.3) can be used to compute the near field of a DRM (see, e.g., Mackowski and Mishchenko 2013), the applicability of this direct approach is still limited in terms of the number of constituent particles and the overall size of the particulate volume relative to the wavelength.
