A fully integrated charge sharing active decap scheme for power supply noise suppression (2015)

Power supply noise has become a major challenge for proper operation of circuits with continuous scaling of CMOS technology along with supply voltage scaling. Conventional passive decoupling capacitors exhibit significant die area penalty resulting in a limited regulation effect. This paper presents a fully integrated charge-sharing-based active decap scheme for power supply noise suppression. The proposed idea is based on allocating a portion of the available passive decap to be used as an active decap that is charged up to a higher voltage and shares its boosted charge with the noisy rail upon droop detection. The proposed scheme uses a charge pump for providing the higher voltage node, as well as a detector circuit for droop detection. The system is implemented in 32 nm CMOS process, and achieves up to ~47% worst-case droop reduction with reduced ringing and settling time, at minimal area and power penalties.
Progress of Spark Plasma Sintering (SPS) Method, Systems, Ceramics Applications and Industrialization (2021)

The spark plasma sintering (SPS) method is of great interest to the powder and powder metallurgy industry and material researchers of academia for both product manufacturing and advanced material research and development. Today in Japan, a number of SPS products for different industries have already been realized. Today’s fifth-generation SPS systems are capable of producing parts of increasing size, offering improved functionality, reproducibility, productivity, and cost. For instance, pure nano-Tungsten Carbide WC powder (no additives) is fully densified with a nano-grain-sized structure for glass lens application in the optics industry. The SPS is now moving from scientific academia and/or R&amp;D proto-type materials level usage to practical industry use product stage utilizing in the field of electronics, automotive, mold and die, cutting tools, fine ceramics, clean energy, biomaterials industries, and others. This paper reviews and introduces the peculiar phenomenon of SPS and the progress of SPS technology, method, development of SPS systems, and its industrial product applications.

WSCD 2012 (2012)

WSCD2012 is the second workshop on Web Search Click Data, following WSCD2009. It is a forum for new research relating to Web search usage logs and for discussing desirable properties of publicly released search log datasets. Research relating to search logs has been hampered by the limited availability of click datasets. This workshop comes with a new click dataset based on click logs and an accompanying challenge to predict the relevance of documents based on clicks.
A cell-type specific and enhancer-dependent silencer in the regulation of the expression of the human urokinase plasminogen activator gene (1991)

A transcriptional silencer has been identified in the 5' regulatory region of the human urokinase plasminogen activator (uPA) gene. This region is able to block transcription from the human u-PA as well as the rabbit beta-globin promoters in a cell type specific and orientation independent way. The silencer is enhancer dependent and is active in two cell lines (HeLa and CV-1) which produce little if any uPA, but not in the high uPA producer PC3. Silencing activity and enhancer dependence can be separated: the silencing activity has been localized to the DNA fragment -660 to -536, while the enhancer dependence is located in the -536 to -308 fragment. The DNA sequence of the silencer region contains an element that closely resembles the TGF-beta responsive negative element TIE.
Biochemistry, regulation and potential function of kallistatin. (1995)

Components of the tissue kallikrein-kinin system include tissue kallikrein, kallistatin (kallikrein-binding protein), kininogen, kinin, bradykinin B1 and B2 receptors, and kininases. Tissue kallikrein is a serine proteinase which is capable of cleaving kininogen substrate to release the vasoactive kinin peptide. The binding of kinin to its specific receptor at target organs can produce a wide spectrum of biological effects. Kinin generation is primarily determined by the activity and availability of kallikrein since the level of kininogen is not a rate-limiting factor. Kallikrein levels are controlled by its rate of synthesis, activation, inactivation and clearance. The synthesis of tissue kallikrein is regulated transcriptionally, and its activity is regulated through post-translational processing and inactivation by inhibitors. Kallistatin is a newly discovered serine proteinase inhibitor (serpin) which forms a specific and covalently-linked complex with tissue kallikrein. Kallistatin may regulate tissue kallikrein's activity, bioavailability and clearance rate at the post-translational level. The major site of kallistatin synthesis is the liver with lower expression levels in the pancreas and kidney. Unlike many other serpins which are only present in the plasma, kallistatin is found in various tissues, cells and bodily fluids. The fact that both tissue kallikrein and kallistatin are widely distributed in tissues suggests kallistatin's role as a potential regulator of kallikrein outside the circulation. Protein purification and molecular cloning techniques have been used to study the structure, regulation and function of the components of the kallikrein-kinin system and for exploring their roles in ion transport, inflammation and blood pressure regulation. Considerable progress has been made in recent years to achieve these goals. This article provides an overview of the biochemical properties and potential physiological and pathophysiological roles of kallistatin.
AN ALTERNATE METHOD TO EVALUATE DRIVER DISTRACTION (2002)

Traditional ways of directly measuring visual demand while driving (i.e., extracting eye glance data by manual video tape reduction) are tedious and cumbersome. This paper is a summary of the results on visual demand associated with various telematic tasks. The results are based on the data collected from an empirical study. More specifically, traditional eye glance measures such as Mean Single Glance Time, Number of Glances, Total Glance Time, and Longest Single Eye Glance are compared to other dependent measures such as Static/Dynamic Task Completion Times and the Number of Excursions committed while completing the task. Previous findings indicated that static task completion time is a viable surrogate of dynamic task completion times. Results presented herein provide supportive evidence of previous findings, in addition to the Total Glance Time being a good predictor of other surrogate measures such as lane- keeping performance and task completion times
Stress-Induced Band Gap and Related Phenomena in Gray Tin (1972)

The conductivity and low-field Hall coefficient of high-purity (${N}_{D}\ensuremath{-}{N}_{A}\ensuremath{\sim}5\ifmmode\times\else\texttimes\fi{}{10}^{14}$ ${\mathrm{cm}}^{\ensuremath{-}3}$) and lightly doped ($2\ifmmode\times\else\texttimes\fi{}{10}^{15}\ensuremath{\le}{N}_{D}\ensuremath{\le}2\ifmmode\times\else\texttimes\fi{}{10}^{17}$ ${\mathrm{cm}}^{\ensuremath{-}3}$) $n$-type gray tin subjected to oriented uniaxial compressions have been measured between 1.4 and 100 \ifmmode^\circ\else\textdegree\fi{}K. Stress ($\ensuremath{\chi}$) exceeding 3 \ifmmode\times\else\texttimes\fi{} ${10}^{9}$ ${\mathrm{d}\mathrm{y}\mathrm{n}/\mathrm{c}\mathrm{m}}^{2}$ was achieved in both [001] and [111] orientations. Density-of-states expressions are developed to account for the severe band anisotropies imposed by the strain in the normally degenerate ${\ensuremath{\Gamma}}_{8}^{+}$ conduction and valence bands, and these are employed to determine the band splittings at $\stackrel{\ensuremath{\rightarrow}}{\mathrm{k}}=0$ from the Hall coefficient of the high-purity samples above 15 \ifmmode^\circ\else\textdegree\fi{}K. Shear deformation potentials of $b=\ensuremath{-}2.3\ifmmode\pm\else\textpm\fi{}0.5$ eV and $d\ensuremath{\simeq}\ensuremath{-}4.1$ eV are obtained by this procedure. The Hall coefficient of three high-purity samples below 10 \ifmmode^\circ\else\textdegree\fi{}K is analyzed to find the stress-dependent impurity-ionization energy ${E}_{D}(\ensuremath{\chi})$, and from the measured ${E}_{D}(\ensuremath{\chi})$ for the highest-purity sample an independent determination of $b=\ensuremath{-}2.4$ eV is obtained if ${E}_{D}(\ensuremath{\chi})$ is interpreted as reflecting donor-to---conduction-band activation. However, the measured ${E}_{D}(\ensuremath{\chi})$ for this sample is also found to be consistent with activation from the donor ground state into a ${D}^{\ensuremath{-}}$ band. The stress dependence of the impurity mobility in two of these samples is explained in terms of Sladek's model for exchange jumping between filled and unfilled impurity sites. The piezoresistance of lightly doped samples is attributed to the increased effectiveness of ionized impurity scattering caused by a stress enhancement of the ${\ensuremath{\Gamma}}_{8}^{+}$ density-of-states mass.
Road Surface Networks technology enablers for enhanced ITS (2010)

The increased need for mobility has led to transportation problems like congestion, accidents and pollution. In order to provide safe and efficient transport systems great efforts are currently being put into developing Intelligent Transport Systems (ITS) and cooperative systems. In this paper we extend proposed solutions with autonomous on-road sensors and actuators forming a wireless Road Surface Network (RSN). We present the RSN architecture and design methodology and demonstrate its applicability to queue-end detection. For the use case we discuss the requirements and technological solutions to sensor technology, data processing and communication. In particular the MAC protocol is detailed and its performance assessed through theoretical verification. The RSN architecture is shown to offer a scalable solution, where increased node density offers more precise sensing as well as increased redundancy for safety critical applications. The use-case demonstrates that RSN solutions may be deployed as standalone systems potentially integrated into current and future ITS. RSN may provide both easily deployable and cost effective alternatives to traditional ITS (with a direct impact independent of penetration rate of other ITS infrastructures - i.e., smart vehicles, safe spots etc.) as well as provide fine grain sensory information directly from the road surface to back-end and cooperative systems, thus enabling a wide range of ITS applications beyond current state of the art.

Dendritic Cell Vaccination, Immune Regulation, and Clinical Outcomes in Ovarian Cancer (2013)

Clinical optimism for dendritic cell vaccination against ovarian cancer has been tempered by the knowledge that tumors avail themselves of multiple mechanisms of immune evasion, thus blunting the efficacy of therapeutic vaccination. Mechanisms of immune suppression include infiltration by regulatory T cells (Treg) and myeloid suppressor cell populations, expression of co-inhibitory receptors, and expression of indoleamine 2,3-dioxygenase (IDO). Expression of both B7-H1 and IDO are associated with differentiation and recruitment of Treg, and clinical studies have shown that each of these mechanisms correlates independently with increased morbidity and mortality in ovarian cancer patients. In sharp contrast, recent studies have indicated that Th17 cell infiltration in ovarian cancer correlates with improved patient outcomes and prolonged overall survival. Given that IDO plays a pivotal role in the balance between Treg and Th17 immunity, elucidation of the mechanisms that regulate IDO activity and immune suppression may lead to novel adjuvants to boost the clinical efficacy of dendritic cell vaccination against ovarian cancer and other malignancies.
Abnormal methylation of the calcitonin gene in human colonic neoplasms. (1989)

Earlier studies of the methylation status of total genomic DNA and of specific genes have demonstrated, predominantly, hypomethylation in human neoplasms. However, we have recently documented the presence of new sites of methylation in the calcitonin gene in human lymphomas (100%), small cell lung carcinomas (92%), and acute myeloid leukemias (95%). We now report that these same novel calcitonin gene methylation sites are also a feature of DNA from human colonic adenomas (13 out of 14 studied), colon carcinomas (4/13), and established colon carcinoma cell lines (18/19), despite the presence of overall genomic DNA hypomethylation in these neoplasms. The data provide further evidence that regional increases in DNA methylation, like gene hypomethylation, occur in benign colonic neoplasms prior to malignant transformation. The fact that abnormalities of calcitonin gene methylation are less frequent in DNA from human colonic carcinomas than from adenomas and colon carcinoma cell culture lines is of special interest. This finding suggests that a more heterogeneous population of cells is present in the carcinomas and that the calcitonin gene hypermethylation may be inherent to cells which are initially selected for growth in culture or are capable of prolonged survival under culture conditions.
Development of an Intense Pulsed Characteristic &#x03B3;-Ray Source for Active Interrogation of Special Nuclear Material (2007)

An intense source of characteristic gamma-rays is developed as a potential probe to identify special nuclear material. A pinch-reflex ion diode is operated on the Gamble II pulsed power generator to produce proton beams with 270-kA peak current and 2.0-MV peak voltage. These beams bombard a PTFE (Teflon) target to produce characteristic gamma-rays by the <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">19</sup> F(p,alphagamma) <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">16</sup> O reaction with energies of 6.13, 6.92, and 7.12 MeV and with an intensity of 3.1x10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sup> gamma-rays into 4pi in a single 50-ns duration pulse. Simple ballistic transport is used to transport the proton beam one meter so that the gamma-ray signal is separated in time and space from the diode bremsstrahlung pulse.
Process Study and Characterization of VO2Thin Films Synthesized by ALD Using TEMAV and O3Precursors (2012)

Vanadium oxide (VO2) thin films were prepared by atomic layer deposition using TEMAV (tetrakis[ethylmethylamido]vanadium) precursor and ozone as the reactant gas. Study on the precursor as well as oxidizer doses and temperature dependence showed none of them exhibited the characteristics of ideal ALD. The VO2 phase formation pathways, its process window, and surface roughness are found to be sensitive to the anneal conditions applied and the substrate used. The VO2 morphology on Al2O3 was found to be island-like whereas on Si/SiO2 either a nano particle formation or a continuous film was obtained. GIXRD demonstrated the VO2 crystallization window to be very narrow on Al2O3 and thick SiO2 while a relatively broad window is obtained on 1 nm SiO2. A reversible change in sheet resistance was measured with more than three orders of magnitude for a 30 nm film.
F-actin by N-(4-azidobenzoyl)-putrescine (1992)

The bifunctional reagent N-(4-azidobenzoyl)-putrescine was synthesized and covalently bound to rabbit skeletal muscle actin. The incorporation was mediated by guinea pig liver transglutaminase under conditions similar to those described by Takashi (1988, Biochemistry 27, 938-943); up to 0.5 M/M were incorporated into G-actin, whereas F-actin was refractory to incorporation. Peptide fractionation showed that at least 90% of the label was bound to Gln-41. The labeled G-actin was polymerized, and irradiation of the F-actin led to covalent intermolecular cross-linking. A cross-linked peptide complex was isolated from a tryptic digest of the cross-linked actin in which digestion was limited to arginine; sequence analysis as well as mass spectrometry indicated that the linked peptides contained residues 40-62 and residues 96-116, and that the actual cross-link was between Gln-41 and Lys113. Thus the y-carboxyl group of Gln-41 must be within 10.7 A of the side chain (probably the amino group) of Lys-I13 in an adjacent actin monomer. In the atomic model for F-actin proposed by Holmes et al. (1990, Nuture 347, 44-49), the a-carbons of these residues in adjacent monomers along the two-start helices are sufficiently close to permit cross-linking of their side chains, and, pending atomic resolution of the side chains, the results presented here seem to support the proposed model.
P‐173: New Triazine Derived Hosts for Next Generation Phosphorescent OLEDs with Enhanced Lifetime and Stability (2011)

Abstract We have developed new phosphorescent hosts having an electron transporting triazine molecular skeleton connected to hole transporting carbazolyl moieties, designed in order to attain high thermal stability, triplet energy sufficiently high enough to be compatible with phosphorescent green dopants. Green phosphorescent OLEDs using PH2 and PH3 achieved longer lifetime (T 80 = 37h, 22h at L 0 of 10000nits), seven fold increase in power efficiency at low driving voltage (∼ 4V) compared to CBP, with 17% external quantum efficiency.
How Comparable are Microbial Electrochemical Systems around the Globe? An Electrochemical and Microbiological Cross‐Laboratory Study (2021)

A cross-laboratory study on microbial fuel cells (MFC) which involved different institutions around the world is presented. The study aims to assess the development of autochthone microbial pools enriched from domestic wastewater, cultivated in identical single-chamber MFCs, operated in the same way, thereby approaching the idea of developing common standards for MFCs. The MFCs are inoculated with domestic wastewater in different geographic locations. The acclimation stage and, consequently, the startup time are longer or shorter depending on the inoculum, but all MFCs reach similar maximum power outputs (55±22 μW cm<sup>-2</sup> ) and COD removal efficiencies (87±9 %), despite the diversity of the bacterial communities. It is inferred that the MFC performance starts when the syntrophic interaction of fermentative and electrogenic bacteria stabilizes under anaerobic conditions at the anode. The generated power is mostly limited by electrolytic conductivity, electrode overpotentials, and an unbalanced external resistance. The enriched microbial consortia, although composed of different bacterial groups, share similar functions both on the anode and the cathode of the different MFCs, resulting in similar electrochemical output.

Outstanding Scientific Achievement Award Lecture 2011: Defeating Diabesity (2012)

Tschp is internationally recognized for his work on how gut-brain communication regulates appetite and metabolism and for combining groundbreaking discovery with translational potential. A review of his peer-reviewed publication record and the breadth of his co-authors is a testament to his ability to build teams to advance science. Early in his career, Dr. Tschp reported on the orexigenic, adipogenic, and metabolic effects of ghrelin. This added a pathway to the model of body weight and glucose control and established a novel set of drug targets for the treatment of the metabolic syndrome. His report of the efficacy of novel gut hormone coagonists targeting glucagon-like peptide 1 and glucagon receptors to reduce body weight and improve glucose tolerance broke new ground and offered novel clinical approaches for the treatment of diabetes and obesity. Dr. Tschp is an influential voice explaining diabetes to the public and describing the scientific progress being made to improve lives.
Behavior of misfit dislocations in semipolar InGaN/GaN grown by MOVPE (2011)

Abstract A microstructure in an InGaN/GaN layer grown at the semipolar direction was observed in detail by means of transmission electron microscopy (TEM) in order to analyze the behaviour of dislocations. A (11 $ \bar 2 $ 2) GaN layer was first deposited on a maskless r (1 $ \bar 1 $ 02)‐plane patterned‐substrate, and then an In x Ga 1‐ x N ( x =0.10, 0.24) was overgrown to be about 1 μm in thickness. Dislocations near the interface of InGaN/GaN are classified into several types: 1 Threading dislocations lying on (0001). 2. Misfit dislocations lying on the interface of InGaN/GaN. 3. Dislocations along [1 $ \bar 1 $ 00] at a certain distance from the interface. 4. Dislocations newly formed at the interface and developing along [11 $ \bar 2 $ 0] on (0001). 5. Partial dislocations accompanied with a stacking fault on (0001). It was found that the misfit dislocations are arrayed in pairs at the direction along [1 $ \bar 1 $ 00] on the interface of (11 $ \bar 2 $ 2). Burgers vector of the misfit dislocations was found to be B = &lt;2 $ \bar 1 $ $ \bar 1 $ 3&gt;/3. In case of B = [ $ \bar 1 $ $ \bar 1 $ 23]/3, they are edge dislocations. The densities of dislocations and stacking faults increase with the In‐content in InGaN. (© 2012 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
