Image Fusion With a Dental Panoramic X-ray Image and Face Image Acquired With a KINECT (2017)

The aim of this study was to make a fusion image combined with a patient's face image and three dimensional teeth and jaw-bone image reconstructed with panoramic x-ray data. To make a face image, we used a KINECT sensor that was attached to the arm of the dental panoramic x-ray system. The xray tube and detector were located opposite to each other inside the arm, and the arm rotated around the patient's head. We used depth data measured by the KINECT sensor to make a three dimensional face image of the patient. The three dimensional teeth and jaw-bone image at the standard dental arch was made with the tomosynthesis technique. The location of the standard dental arch was measured in advance with the dedicated phantom. The registration of two images was conducted with tungsten rubber markers. The experiments with a volunteer showed that the reconstructed fusion image was acceptable for clinical use.
Secure Communication in Multiantenna Cognitive Radio Networks With Imperfect Channel State Information (2011)

In this paper, we address the issue of optimal transmitter design to achieve physical layer security for a multiple-input single-output (MISO) cognitive radio network (CRN), in which a secondary user transmitter (SU-Tx) sends confidential information to a SU receiver (SU-Rx) on the same frequency band with a primary user (PU) in the presence of an eavesdropper receiver (ED-Rx). It is assumed that all the channel state information (CSI) of the secondary, primary and eavesdropper channels is not perfectly known at the SU-Tx. The optimal transmitter design, under the restriction of Gaussian signaling without preprocessing of information, involves a nonconvex semiinfinite optimization problem which maximizes the rate of the secondary link while avoiding harmful interference to the PU and keeping the eavesdropper totally ignorant of the messages sent regardless of the uncertainties in the CSI. We propose two approaches to solve this challenging optimization problem. The first one relates the original problem to a sequence of semiinfinite capacity-achieving transmitter design problems in an auxiliary CRN without any eavesdropper, which can then be solved through transformations and using convex semidefinite programs (SDPs). The second approach explores the hidden convexity of the problem and hence transforms it into a single SDP, which significantly reduces the computational complexity. Furthermore, a few heuristic beamforming solutions for the ease of implementation are also introduced. Finally, simulation results are presented to evaluate the performance of the proposed optimal and suboptimal solutions.
Disposal of iron by a mutant form of lipocalin 2 (2016)

Iron overload damages many organs. Unfortunately, therapeutic iron chelators also have undesired toxicity and may deliver iron to microbes. Here we show that a mutant form (K3Cys) of endogenous lipocalin 2 (LCN2) is filtered by the kidney but can bypass sites of megalin-dependent recapture, resulting in urinary excretion. Because K3Cys maintains recognition of its cognate ligand, the iron siderophore enterochelin, this protein can capture and transport iron even in the acidic conditions of urine. Mutant LCN2 strips iron from transferrin and citrate, and delivers it into the urine. In addition, it removes iron from iron overloaded mice, including models of acquired (iron-dextran or stored red blood cells) and primary (Hfe<sup>-/-</sup>) iron overload. In each case, the mutants reduce redox activity typical of non-transferrin-bound iron. In summary, we present a non-toxic strategy for iron chelation and urinary elimination, based on manipulating an endogenous protein:siderophore:iron clearance pathway.

Differential electrophysiological response during rest, self-referential, and non–self-referential tasks in human posteromedial cortex (2011)

The electrophysiological basis for higher brain activity during rest and internally directed cognition within the human default mode network (DMN) remains largely unknown. Here we use intracranial recordings in the human posteromedial cortex (PMC), a core node within the DMN, during conditions of cued rest, autobiographical judgments, and arithmetic processing. We found a heterogeneous profile of PMC responses in functional, spatial, and temporal domains. Although the majority of PMC sites showed increased broad gamma band activity (30-180 Hz) during rest, some PMC sites, proximal to the retrosplenial cortex, responded selectively to autobiographical stimuli. However, no site responded to both conditions, even though they were located within the boundaries of the DMN identified with resting-state functional imaging and similarly deactivated during arithmetic processing. These findings, which provide electrophysiological evidence for heterogeneity within the core of the DMN, will have important implications for neuroimaging studies of the DMN.

Review of magnetohydrodynamic pump applications (2016)

Magneto-hydrodynamic (MHD) principle is an important interdisciplinary field. One of the most important applications of this effect is pumping of materials that are hard to pump using conventional pumps. In this work, the progress achieved in this field is surveyed and organized according to the type of application. The literature of the past 27 years is searched for the major developments of MHD applications. MHD seawater thrusters are promising for a variety of applications requiring high flow rates and velocity. MHD molten metal pump is important replacement to conventional pumps because their moving parts cannot stand the molten metal temperature. MHD molten salt pump is used for nuclear reactor coolants due to its no-moving-parts feature. Nanofluid MHD pumping is a promising technology especially for bioapplications. Advantages of MHD include silence due to no-moving-parts propulsion. Much progress has been made, but with MHD pump still not suitable for wider applications, this remains a fertile area for future research.
Analgesic, Anticonvulsant and Antiparkinsonian Activities of Some Synthesized 2,6-bis(Tetracarboxamide)-pyridine and Macrocyclic Tripeptide Derivatives (2016)

A series of synthesized 2,6-bis(tetracarboxamide)-pyridine and macrocyclic tripeptide derivatives 1-6 were previously prepared and screened as antimicrobial, anti-inflammatory and anticancer agents. The compounds for evaluation of analgesic, anticonvulsant and antiparkinsonian activities were used. Analgesic activities of selected compounds determined by hot plate assay, all tested compounds showed this property. Anticonvulsant activities of selected compounds measured their abilities to antagonize yohimbine-induced clonic seizure, all tested compounds showed this property. The antiparkinsonian activity measured by the ability of compounds to protect animals against the parkinsonian like signs induced by agonists, all tested compounds showed this property. All tested compounds showed analgesic, antipakinsonian and anticonvulsant activities and the order for these activities were 5b, 6a, 3, 5a, 5c, 4, 6c, 2, 6b and 1.
On the choice of the appropriate AES data encryption method for ZigBee nodes (2010)

Abstract This paper describes the experiments that have been conducted to determine the optimal implementation method for AES (Advanced Encryption Standard) data encryption in a ZigBee network in terms of energy consumption. Four possible scenarios have been considered. The first one is a freely available AES‐cryptographic algorithm on the processor which controls the ZigBee nodes. The second also involves the processor but is based on a proprietary, highly optimized algorithm. The other methods are based on hardware implementations. Whereas the third option is based on a cryptographic block, embedded in the ZigBee node controller, the last solution utilizes an AES128‐CBC‐MAC hardware co‐processor embedded on a Spartan 3A FPGA. The ZigBee modules in the network contain an 8‐bit microcontroller which takes care of the ZigBee protocol stack—and the encryption calculations in all but the last case. All approaches are examined and compared. We show that the usage of a microcontroller with an on‐board AES processor is the optimal design choice for a new hardware platform. An optimized software library gives the best results when extending an existing platform. This paper gives developers an idea of the amount of energy they can gain/lose by choosing one of the four solutions. Copyright © 2010 John Wiley &amp; Sons, Ltd.
OC105: Fetoscopic surgery in triplet pregnancies—a multicenter case series (2004)

The purpose of this study was to evaluate the feasibility of fetoscopic surgery in complicated monochorionic and dichorionic triplet pregnancies. Case series of fetoscopic surgery in 12 cases of monochorionic (n = 5) or dichorionic (n = 7) triamniotic triplets complicated by severe feto-fetal transfusion (n = 8), twin reversed arterial perfusion sequence (n = 3) or discordant for an anomaly (n = 1). Six underwent cord occlusion and 6 had laser coagulation of the vascular anastomoses. All procedures were successfully completed and the outcome was comparable to that reported for similar procedures in twins. Eighty three percent of fetuses survived and 13% had long term problems. Fetoscopic surgery may be considered as a therapeutic option in complicated triplet pregnancies, with results similar to those found in twins.
Stereoselectivity of the Generation of 3-Mercaptohexanal and 3-Mercaptohexanol by Lipase-Catalyzed Hydrolysis of 3-Acetylthioesters (2003)

The enantioselectivity of the generation of 3-mercaptohexanal and 3-mercaptohexanol, two potent sulfur-containing aroma compounds, by lipase-catalyzed hydrolysis of the corresponding 3-acetylthioesters was investigated. The stereochemical course of the kinetic resolutions was followed by capillary gas chromatography using modified cyclodextrins as chiral stationary phases. The enzyme preparations tested varied significantly in terms of activity and enantioselectivity (E). The highest E value (E = 36) was observed for the hydrolysis of 3-acetylthiohexanal catalyzed by lipase B from Candida antarctica resulting in (S)-configured thiol products. Immobilization of the enzyme (E = 85) and the use of tert-butyl alcohol as cosolvent (E = 49) improved the enantioselectivity. Modification of the acyl moiety of the substrate (3-benzoylthiohexanal) had no significant impact. The sulfur-containing compounds investigated possess attractive odor properties, and only one of the enantiomers exhibits the pleasant citrus type note. Keywords: Thioester; thiol; lipase; enantioselectivity; 3-acetylthiohexanal; 3-acetylthiohexanol
Inverter-Driven Synchronous Motors for Constant Power (1996)

Inverter-driven synchronous motors are widely used in high-performance variable-speed drive systems. In this article, the effects of machine parameters and the operating characteristics with respect to several types of synchronous motors-which include synchronous reluctance motors, surface permanent magnet synchronous motors, and interior permanent magnet synchronous motors-are examined. The optimum current vector producing the maximum output power at any speed is derived considering both current and voltage constraints.
Selective Angiotensin Receptor Antagonism with Valsartan Decreases Arterial Stiffness Independently of Blood Pressure Lowering in Hypertensive Patients (2005)

Angiotensin II plays a key role in the development of vascular disease. We examined the long-term effects of selective angiotensin II receptor (ATR) blockade with valsartan on arterial wall stiffness. Brachial to ankle pulse wave velocity (baPWV) was measured in 28 women and 25 men with hypertension (mean age: 62+/-2 years). The measurements were repeated after 24 weeks of treatment with valsartan, 40 to 160 mg/day, with (n=10) or without (n=36) concomitant statin therapy. By multiple regression analysis, baseline baPWV was correlated with age (p<0.001), systolic blood pressure (SBP, p<0.0001), body mass index (p=0.018), and pulse pressure (p=0.005), but not with total cholesterol (p=0.446). Valsartan lowered mean SBP and diastolic blood pressure (DBP) from 155+/-3 to 140+/-3 mmHg and from 90+/-2 to 82+/-2 mmHg, respectively, and mean baPWV from 1,853+/-49 to 1,682+/-52 cm/s. Lowering of baPWV was not influenced by statin therapy. An overlap analysis was performed to separate the effect of angiotensin II receptor blockade from that of blood pressure (BP) lowering. The decrease in the baPWV value of 1,794+/-46 cm/s before valsartan (n=39) vs. 1,663+/-45 cm/s during valsartan (p=0.048, n=31) at a similar mean SBP level (149+/-2 vs. 146+/-3 mmHg, p=0.304) confirmed that ATR blockade had a beneficial effect independent of BP lowering. SBP strongly influences baPWV. However, the decrease in baPWV with valsartan was independent of BP lowering. Statins had no synergistic effect on baPWV. Lowering of baPWV may account for the therapeutic benefit conferred by valsartan independent of its BP-lowering effect.
Effects of plasma parameters on viscosity (1998)

A numerical code is developed to study the effect of ion density and temperature (as well as ion pressure and temperature gradients) on the amplitude of the local maxima of the poloidal viscosity with respect to the poloidal Mach number using the model developed by Shaing (1993). The sum of the poloidal viscosity and ion-neutral collisions is determined from the dependence of the plasma radial current on the radial electric field in a biased electrode experiment. The experimental results in the interchangeable module stellarator agree qualitatively with the predictions of the numerical calculation regarding the effects of variation of ion density and temperature on viscosity.
THE FLUORESCENT PROPERTIES OF RINGWORM OF THE SCALP AS AN AID IN DIAGNOSIS (1929)

Ultraviolet light when passed through a glass filter containing nickel oxide will cause certain substances to fluoresce in a characteristic manner. Wood's glass, invented by Prof. R. W. Wood of Johns Hopkins University, or Chance's ultraviolet glass, developed by Chance Brothers of Smethwick,<sup>1</sup>is a deep violet nickel oxide glass, which transmits only the shortest rays of the visible spectrum and between 70 and 80 per cent of the ultraviolet rays in the region between 3,000 and 4,000 angstrom units.<sup>1</sup>Solutions of eosin, quinine, quinidine, zinc sulphate and sodium salicylate give a distinctive fluorescence under such a light. Petrolatum, hydrous wool fat, mustard dried on cloth,<sup>1</sup>dried blood and semen,<sup>2</sup>and cerumen from the ear can be detected under Wood's light by their fluorescent properties. The normal skin and hair fluoresce faintly, the finger-nails fluoresce rather more brightly with a bluish tinge, and the teeth appear

Effect of Posterior Condylar Offset on Cruciate-Retaining Mobile TKA (2009)

The objective of this article was to evaluate the effect of the change of posterior condylar offset to range of motion (ROM) and clinical results after computer-assisted cruciate-retaining mobile-bearing total knee arthroplasty (TKA). A total of 111 knees underwent cruciate-retaining mobile-bearing TKAs under computer-assisted navigation from January 2005 to September 2007. All cases were primary osteoarthritis and had <15 degrees of valgus or varus deformity. We divided patients into 4 groups according to change of posterior condylar offset, which was measured by postoperative minus preoperative posterior condylar offset (group 1: <-2 mm; group 2: -2-0 mm; group 3: 0-+2 mm; group 4: >2 mm). Preoperative age, thigh girth, body mass index, flexion contracture, further flexion, Hospital for Special Surgery (HSS) score, Knee Society (KS) knee score, and KS functional score did not show significant difference between groups. The measured change of posterior condylar offset ranged from +3.70 to -3.95 mm with a mean value of -1.67 mm. Postoperatively, there were no statistical differences between each group on flexion contracture (P=.522), further flexion (P=.442), HSS score (P=.116), KS knee score (P=.479), or KS functional score (P=.578). We could find no significant difference between ROM or clinical results with computer-assisted cruciate-retaining mobile-bearing TKAs in the comparison of groups according to changes of posterior condylar offset.
Tolerability of a Fully Maturated Cheese in Cow’s Milk Allergic Children: Biochemical, Immunochemical, and Clinical Aspects (2012)

58% of patients clinically reactive to CM tolerated fully maturated PR. The preliminary digestion of CAS induced by PR maturation process, facilitating a further loss of allergenic reactivity during gut digestion, might explain the tolerance. This hypothesis seems to work when no IgE sensitization to ISAC BLG is detected.
A fuzzy analysis approach for part‐machine grouping in cellular manufacturing systems (2002)

Among the many accepted clustering techniques, the fuzzy clustering approaches have been developed over the last decades. These approaches have been applied to many areas in manufacturing systems. In this paper, a fuzzy clustering approach is proposed for selecting machine cells and part families in cellular manufacturing systems. This fuzzy approach offers a special advantage over existing clustering approaches as it presents the degree of membership of the machine or part associated with each machine cell or part family allowing users flexibility in formulating machine cells and part families. The proposed algorithm is extended and validated using numerical examples to demonstrate its application in cellular manufacturing.
Uncertainties in Ocean Latent Heat Flux Variations over Recent Decades in Satellite-Based Estimates and Reduced Observation Reanalyses (2020)

Abstract Four state-of-the-art satellite-based estimates of ocean surface latent heat fluxes (LHFs) extending over three decades are analyzed, focusing on the interannual variability and trends of near-global averages and regional patterns. Detailed intercomparisons are made with other datasets including 1) reduced observation reanalyses (RedObs) whose exclusion of satellite data renders them an important independent diagnostic tool; 2) a moisture budget residual LHF estimate using reanalysis moisture transport, atmospheric storage, and satellite precipitation; 3) the ECMWF Reanalysis 5 (ERA5); 4) Remote Sensing Systems (RSS) single-sensor passive microwave and scatterometer wind speed retrievals; and 5) several sea surface temperature (SST) datasets. Large disparities remain in near-global satellite LHF trends and their regional expression over the 1990–2010 period, during which time the interdecadal Pacific oscillation changed sign. The budget residual diagnostics support the smaller RedObs LHF trends. The satellites, ERA5, and RedObs are reasonably consistent in identifying contributions by the 10-m wind speed variations to the LHF trend patterns. However, contributions by the near-surface vertical humidity gradient from satellites and ERA5 trend upward in time with respect to the RedObs ensemble and show less agreement in trend patterns. Problems with wind speed retrievals from Special Sensor Microwave Imager/Sounder satellite sensors, excessive upward trends in trends in Optimal Interpolation Sea Surface Temperature (OISST AVHRR-Only) data used in most satellite LHF estimates, and uncertainties associated with poor satellite coverage before the mid-1990s are noted. Possibly erroneous trends are also identified in ERA5 LHF associated with the onset of scatterometer wind data assimilation in the early 1990s.
Aging in inbred strains of mice: study design and interim report on median lifespans and circulating IGF1 levels (2009)

To better characterize aging in mice, the Jackson Aging Center carried out a lifespan study of 31 genetically-diverse inbred mouse strains housed in a specific pathogen-free facility. Clinical assessments were carried out every 6 months, measuring multiple age-related phenotypes including neuromuscular, kidney and heart function, body composition, bone density, hematology, hormonal levels, and immune system parameters. In a concurrent cross-sectional study of the same 31 strains at 6, 12, and 20 months, more invasive measurements were carried out followed by necropsy to assess apoptosis, DNA repair, chromosome fragility, and histopathology. In this report, which is the initial paper of a series, the study design, median lifespans, and circulating insulin-like growth factor 1 (IGF1) levels at 6, 12, and 18 months are described for the first cohort of 32 females and 32 males of each strain. Survival curves varied dramatically among strains with the median lifespans ranging from 251 to 964 days. Plasma IGF1 levels, which also varied considerably at each time point, showed an inverse correlation with a median lifespan at 6 months (R = -0.33, P = 0.01). This correlation became stronger if the short-lived strains with a median lifespan < 600 days were removed from the analysis (R = -0.53, P < 0.01). These results support the hypothesis that the IGF1 pathway plays a key role in regulating longevity in mice and indicates that common genetic mechanisms may exist for regulating IGF1 levels and lifespan.
