CONFIGURATIONS OF HIGH PRESSURE ELECTRODELESS DISCHARGES. (1968)

Two cases of organized chronic subdural hematoma were presented. The first case had a one-year history of disorientation and right hemiparesis. CT scan revealed a low density area with linear high density in its medial margin, suggesting chronic subdural hematoma on the left frontal convexity. Surgery was performed expecting to remove the hematoma. There was, however, only a little fluid inside with thick membranous tissue. The second case, who has Crouzon disease, presented a one-year history of pseudobulbar palsy and tetraparesis after surgery for chronic subdural hematoma and hydrocephalus. The diagnosis of organized subdural hematoma was made at the time of reoperation which was performed expecting to remove the recurrent chronic subdural hematoma. Plain CT, done after admission to our hospital, showed homogeneous low density area remaining in the bilateral frontal convexity. Infusion scan revealed marked enhancement of the medial margin of the low density area. The lesion was demonstrated as a low intensity area by T1-weighted magnetic resonance images (MRI). Marked enhancement was noted around the low intensity area after the infusion of Gd-DTPA. Although it is very hard to make a diagnosis of organized chronic subdural hematoma using only the CT scan preoperatively, combination of the CT scan and MRI with Gd-DTPA enhancement seemed to be very useful for this purpose.

TSV density-driven global placement for 3D stacked ICs (2011)

Via-first through-silicon vias (TSVs) are manufactured through bulk silicon and connected to landing pads in metal layers. Landing pads are made large enough to cover the top surface of TSVs entirely so that TSV-to-landing pad connections become invulnerable to uncertainties such as misalignment between TSVs and landing pads. Large landing pads, however, could lead to metal density mismatch problems, which result in nonuniform topography. In this paper, we investigate the metal density mismatch problem in 3D ICs and propose a TSV density-driven 3D global placement algorithm to minimize topography variation in 3D IC layouts. The experimental results show that we achieve 1.86× improvement in the range of metal 1 densities and 2.10× improvement in the maximum metal 1 density gradient with just 2.3% wirelength overhead. We also present additional studies such as the impact of landing pad size on metal density.
Localization of the human melanocortin-5 receptor gene (MC5R) to chromosome band 18p11.2 by fluorescence in situ hybridization (1995)

The recently cloned novel MC5R gene is suggested to be a mediator of neural functions of the melanocortic peptides, such as melanocyte-stimulating hormone (MSH) and adrenocorticotropic hormone (ACTH). We now report the localization of the human MC5R locus to chromosome 18p11.2.
Polynomial Simulations of Decohered Quantum Computers (1996)

We define formally decohered quantum computers (using density matrices), and present a simulation of them by a probabalistic classical Turing Machine. We study the slowdown of the simulation for two cases: (1) sequential quantum computers, or quantum Turing machines(QTM), and (2) parallel quantum computers, or quantum circuits. This paper shows that the computational power of decohered quantum computers depends strongly on the amount of parallelism in the computation. The expected slowdown of the simulation of a QTM is polynomial in time and space of the quantum computation, for any non zero decoherence rate. This means that a QTM subjected to any amount of noise is worthless. For decohered quantum circuits, the situation is more subtle and depends on the decoherence rate, eta. We find that our simulation is efficient for circuits with decoherence rate higher than some constant, but exponential for general circuits with decoherence rate lower than some other constant. Using computer experiments, we show that the transition from exponential cost to polynomial cost happens in a short range of decoherence rates, and exhibit the phase transitions in various quantum circuits.
Anticancer Activities of Thelephantin O and Vialinin A Isolated from Thelephora aurantiotincta (2011)

Thelephora aurantiotincta is an edible mushroom belonging to the genus Thelephora; it grows in symbiosis with pine trees. Recently, phytochemical investigations have revealed that the genus Thelephora is an abundant source of p-terphenyl derivatives. However, their bioactivity has not yet been well characterized. In screening for natural materials with anticancer activity, a T. aurantiotincta ethanol extract (TAE) was found to decrease cell viability in human hepatocellular carcinoma cells (HepG2). In this study, a new p-terphenyl derivative, thelephantin O, and a known compound, vialinin A, were isolated as the principal bioactive components of TAE. These compounds decreased cell viability in HepG2 and human colonic carcinoma cells (Caco2), but not in noncancerous human hepatocytes. This is the first report of the isolation from T. aurantiotincta of selective cytotoxic agents against cancer cells.
About Perfluoropolyhedranes, Their Electron‐Accepting Ability and Questionable Supramolecular Hosting Capacity (2023)

Abstract Polyhedral molecules are appealing for their eye‐catching architecture and distinctive chemistry. Perfluorination of such, often greatly strained, compounds is a momentous challenge. It drastically changes the electron distribution, structure and properties. Notably, small high‐symmetry perfluoropolyhedranes feature a centrally located, star‐shaped low‐energy unoccupied molecular orbital that can host an extra electron within the polyhedral frame, thus producing a radical anion, without loss of symmetry. This predicted electron‐hosting capacity was definitively established for perfluorocubane, the first perfluorinated Platonic polyhedrane to be isolated pure. Hosting atoms, molecules, or ions in such “cage” structures is, however, all but forthright, if not illusionary, offering no easy access to supramolecular constructs. While adamantane and cubane have fostered numerous applications in materials science, medicine, and biology, specific uses for their perfluorinated counterparts remain to be established. Some aspects of highly fluorinated carbon allotropes, such as fullerenes and graphite, are briefly mentioned for context.

Impact of Maximum Tongue Pressure in Patients with Jaw Deformities Who Underwent Orthognathic Surgery (2022)

Malocclusion and morphological abnormalities of the jawbone often affect the stomatognathic function and long-term postoperative stability in patients with jaw deformities. There are few reports on the effect of maximum tongue pressure (MTP) in these patients. We investigated the relationship between the MTP and jawbone morphology and the effect of the MTP on surgery in 42 patients with jaw deformity who underwent surgical orthodontic treatment at Hiroshima University Hospital. The MTP was measured using a tongue pressure measurement device; the average value was considered as the MTP. Based on the MTP measured before surgery, patients were classified into the high- or the low-MTP group. The clinical findings and results of the cephalometric analysis were compared. Posterior movement of the mandible in the high-MTP group was significantly lower than that in the low-MTP group. The ANB angle, overjet, and overbite in the high-MTP group were significantly smaller than those in the low-MTP group. On the other hand, there was no difference between the two groups in the measured values, indicating a labial inclination of the anterior teeth (U1 to SN, U1 to FH, IMPA, and FMIA). MTP has been suggested to affect mandibular prognathism in patients with jaw deformities.

Research Activities on Supercritical Fluid Science in Food Biotechnology (2010)

This article serves as an overview, introducing the currently popular area of supercritical fluids and their uses in food biotechnology. Within each application, and wherever possible, the basic principles of the technique, as well as a description of the history, instrumentation, methodology, uses, problems encountered, and advantages over the traditional, non-supercritical methods are given. Most current commercial application of the supercritical extraction involve biologically-produced materials; the technique may be particularly relevant to the extraction of biological compounds in cases where there is a requirement for low-temperature processing, high mass-transfer rates, and negligible carrying over of the solvent into the final product. Special applications to food processing include the decaffeination of green coffee beans, the production of hops extracts, the recovery of aromas and flavors from herbs and spices, the extraction and fractionation of edible oils, and the removal of contaminants, among others. New advances, in which the extraction is combined with reaction or crystallization steps, may further increase the attractiveness of supercritical fluids in the bioprocess industries. To develop and establish a novel and effective alternative to heating treatment, the lethal action of high hydrostatic pressure CO(2) on microorganisms, with none or only a minimal heating process, has recently received a great deal of attention.
Protein Phosphatase: Structural Features, Physiological Significance and Synthetic Inhibitors (2004)

Protein phosphatases are important in a sense that they regulate the phosphorylation level of various proteins and in turn many physiological processes. Aberration in a fine tune among protein phosphatases and their counterparts, protein kinases, results in various diseases. Hence, the inhibitors of these enzymes have gained importance in disease treatments. In recent years, some natural and synthetic compounds have shown promising activity for protein phosphatase inhibition. This review describes, in a brief, strategies used to design and synthesis various molecules having significant potential to inhibit some crucial protein phosphatases and also gives an overview of different kinds of protein phosphatase enzymes and their physiological significance. Keywords: Protein Phosphatase, phosphorylation, phosphatases
The role of PET probe–guided open biopsy in managing patients with lymphoma. (2011)

e18547 Background: The aim of this study was to determine the correlation between results acquired via both (18)F-flourodeoxyglucose positron emission tomography (FDG PET) probe guided open biopsy and core biopsy, and to assess the validity of core biopsy as the current standard of care when deriving a diagnosis of lymphoma. Methods: We performed a retrospective chart review of 10 patients who had failed core biopsies. All the patients had previous disease, and were being evaluated for recurrent disease because of new FDG avid lymph nodes. Our patient group included six males and four females, ranging from 19 to 76 years of age. The manner of core biopsy employed varied with six patients getting computed tomography guidance, one patient by ultrasound, one patient by esophagogastroduodenoscopy, one by thoracoscopy, and one bone marrow biopsy. Results: On the preliminary core biopsy, CT guided biopsy was indeterminate for 3 out of 6 patients, negative for 2 out of 6 patients, and unable to differentiate the subtype and growth pattern for 1 patient. The US-guided, EGD, and bone marrow biopsies for the remaining 4 patients were all negative. In four separate instances, patients had a negative biopsy even on repeat attempt, two cores and two non PET probe-guided open biopsies. PET probe-guided open biopsy correctly diagnosed all these patients, including the specific subtype and growth pattern. The most common diagnosis was malignant non-Hodgkin’s lymphoma (6/10), followed by Hodgkin’s lymphoma (4/10). Conclusions: Our series suggests that FDG PET probe guided open biopsy is instrumental in diagnosis and classification of recurrent lymphoma. Similar findings might also apply to the initial diagnosis of lymphoma. Core biopsy alone, even when guided by other imaging tools, is often insufficient for a correct diagnosis.
Determining the best location of smoke sensor in office room (2012)

Smoke detectors are considered to be the most effective type of fire detectors. But where should they be installed in an office room to give a signal in time? Instructions for installing of smoke detectors are usually given in general terms, thus further information of the best location of smoke detectors would be needed. \n\nThe aim of this Bachelor’s thesis was to determine the best location of the smoke detector in an office room. Research was divided into two subtasks. The first was a comparison of smoke detector installation instructions in 3 different countries (USA, United Kingdom, and Russia). Normative documents in these countries are similar, but each country emphasizes its own parameters which affect decision of the fire engineer. The second subtask was to carry out laboratory experiments. They were conducted to study the air flow patterns in an office room and response times of smoke detectors in different locations. \n\nThe investigated office room was about 11 m2, and there was a desk, chair and computer. The room had supply and exhaust valves. Four smoke detectors, connected to a panel, were placed in different locations (ceiling, walls, alongside of computer, and inside exhaust duct). Smoke generator was put under the table and smoke was introduced to the room as puffs. In reality this might resemble the situation in which the computer starts to burn and produce smoke. As soon as the smoke reached one of the detectors, a lamp was lit in the panel. The response time in seconds for each detector was recorded. Response times of 20 different locations of the smoke detectors were studied.\n\nThe best location according to the results is in points of the ceiling which are close to the expected ignition source and have sufficient air flow movement around them. Location inside exhaust duct gives the best response time, but it requires frequently cleaning of the smoke detector.
The physics of Hanbury Brown--Twiss intensity interferometry: from stars to nuclear collisions (1998)

In the 1950's Hanbury Brown and Twiss showed that one could measure the angular sizes of astronomical radio sources and stars from correlations of signal intensities, rather than amplitudes, in independent detectors. Their subsequent correlation experiments demonstrating quantum bunching of photons in incoherent light beams were seminal in the development of quantum optics. Since that time the technique of "intensity interferometry" has become a valuable probe of high energy nuclear and particle collisions, providing information on the space-time geometry of the collision. The effect is one of the few measurements in elementary particle detection that depends on the wave mechanics of the produced particles. Here we discuss the basic physics of intensity interferometry, and its current applications in high energy nuclear physics, as well as recent applications in condensed matter and atomic physics.
Precise feature extraction from wind turbine condition monitoring signals by using optimised variational mode decomposition (2016)

Reliable condition monitoring (CM) highly relies on the correct extraction of fault‐related features from CM signals. This equally applies to the CM of wind turbines (WTs). Although influenced by slowly rotating speeds and constantly varying loading, extracting fault characteristics from lengthy, nonlinear, non‐stationary WT CM signals is extremely difficult, which makes WT CM one of the most challenge tasks in wind power asset management despites that lots of efforts have been spent. Attributed to the superiorities to empirical mode decomposition and its extension form Hilbert–Huang transform in dealing with nonlinear, non‐stationary CM signals, the recently developed variational mode decomposition (VMD) casts a glimmer of light for the solution for this issue. However, the original proposed VMD adopts default values for both number of modes and filter frequency bandwidth. It is not adaptive to the signal being inspected. As a consequence, it would lead to inaccurate feature extraction thus unreliable WT CM result sometimes. For this reason, a precise feature extraction method based on optimised VMD is investigated. The experiments have shown that thanks to the use of the proposed optimisation strategies, the fault‐related features buried in WT CM signals have been extracted out successfully.
Lithium stimulation of granulopoiesis in diffusion chambers--a model of a humoral, indirect stimulation of stem cell proliferation (1985)

Lithium has been recognized as a stimulator of granulopoiesis both in vivo and in vitro. The mechanism by which lithium provokes this stimulation is unclear, with previous data focusing on such divergent causes as direct effects on progenitor cells v elevations in granulocyte macrophage colony-stimulating activity (GM-CSA) production. In the present study, we used a model system of granulopoiesis in diffusion chambers to study this stimulation of granulopoiesis. Lithium pretreatment of mice followed by a rest period to allow for excretion of the lithium (confirmed by serum assays) revealed a stimulation of progenitor cell growth within the diffusion chambers. No changes in the serum and chamber fluid GM-CSA levels were discernible between the control host mice and the lithium-pretreated mice. These data indicate that lithium stimulates granulopoiesis by an indirect mechanism that does not appear to involve GM-CSA.

Expert Systems: Ready to Hit the Road? (1992)

The article discusses efforts by many departments of transportation to apply expert systems to designing, scheduling and pricing road repair. A typical system called Pavement Rehabilitation Expert System (PARES) is described. It takes information given by the user and processes it through a series of tests until the system is convinced it has determined a proper rehabilitation strategy. The system applies tests called if-then-rules. Diagnosis and suggested treatment can be quite specific, down to the number of inches of new asphalt on the old pavement. Problems associated with it are also discussed. A concrete rehabilitation system called Expert System for Pavement Evaluation and Rehabilitation (EXPEAR) is also described.

Localization of excitons by potential fluctuations and its effect on the Stokes shift in InGaP/InP quantum confined heterostructures (1998)

We present investigations of the temperature evolution of the photoluminescence (PL) and optical absorption spectra of a series of tensile-strained InGaP/InP multiple quantum wells (MQW) samples. As in previous work on compressive-strained InAsP/InP MQW, the results support the assignment of the low temperature PL transitions to recombination from excitonic band-tail states. The energy of such transition is redshifted with respect to the free exciton recombination energy. This results in a large apparent energy difference between PL and optical absorption peaks which is, at 6 K, about 5 meV in the coherently strained samples and less than 1 meV in the partially relaxed ones. The analysis of the low temperature PL line shape which we present enables the determination of the excitonic band-gap energy for all the samples. The difference between the energy of the optical absorption transition and the excitonic band-gap energy thus determined gives a measure of the Stokes shift arising from thermalization effects alone. The values of the Stokes shift thus obtained are in better agreement with the sharpness of the optical absorption transitions which indicate samples of high crystalline quality.

The effects of proton irradiation on the operating voltage constraints of SiGe HBTs (2005)

The effect of proton irradiation on operating voltage constraints in SiGe HBTs is investigated for the first time in 120 GHz and 200 GHz SiGe HBTs. A variety of operating bias conditions was examined during irradiation, including terminals grounded, terminals floating, and forward active (FA) bias operation. The excess base current degradation at 5.0/spl times/10/sup 13/ p/cm/sup 2/ was similar in all cases. BV/sub CEO/ and BV/sub CBO/ showed no significant signs of degradation with irradiation. We also investigated for the first time the impact of radiation on SiGe HBTs biased under so-called "unstable" conditions (i.e., operating point instabilities). In the case of unstable bias conditions, device degradation under proton exposure is significantly different than for stable bias, and bias conditions can play a significant role in the damage process, potentially raising issues from a hardness assurance perspective.
