Neutron-scattering experiments were performed on the undoped and hole-doped ${\mathrm{Ca}}_{2+x}{\mathrm{Y}}_{2\ensuremath{-}x}{\mathrm{Cu}}_{5}{\mathrm{O}}_{10}$, which consists of ferromagnetic edge-sharing ${\mathrm{CuO}}_{2}$ chains. It was previously reported that in the undoped ${\mathrm{Ca}}_{2}{\mathrm{Y}}_{2}{\mathrm{Cu}}_{5}{\mathrm{O}}_{10}$ there is an anomalous broadening of spin-wave excitations along the chain, which is caused mainly by the antiferromagnetic interchain interactions [M. Matsuda et al., Phys. Rev. B 63, 180403(R) (2001)]. A systematic study of temperature and hole concentration dependencies of the magnetic excitations shows that the magnetic excitations are softened and broadened with increasing temperature or doping holes irrespective of $Q$ direction. The broadening is larger at higher $Q$. A characteristic feature is that hole doping is much more effective to broaden the excitations along the chain. It is also suggested that the intrachain interaction does not change so much with increasing temperature or doping although the anisotropic interaction and the interchain interaction are reduced. In the spin-glass phase $(x=1.5)$ and nearly disordered phase $(x=1.67)$ the magnetic excitations are much broadened in energy and $Q$. It is suggested that the spin-glass phase originates from the antiferromagnetic clusters, which are caused by the hole disproportionation.
Spectral analysis of heart rate variability revisited: comparison of the methods (2002)

Since the early 70's, interest in spectral analysis of heart rate variability (HRV) has grown considerably. The clinical significance of the HRV spectrum has been made apparent by studies which have shown it to provide predictors of mortality after myocardial infarction. Unfortunately, there are difficulties in quantitatively interpreting and comparing the results of the many published HRV studies owing to the different methods which have been used in arriving at the HRV spectrum. In particular, most of the methods introduce spectral bias. This study reports a systematic comparison of how effective each of the published methods for estimating the HRV spectrum are in faithfully retrieving the autonomic activity converging on the heart. Moreover, the use of spontaneous HRV activity to estimate the sympathovagal balance is challenged and the 'respiratory-evoked HRV spectrum' is put forward as a more reliable method of obtaining this parameter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bent-core mesogens with biphenyl moieties: observation of a B<sub>7</sub>to B<sub>4</sub>phase transition (2001)

Abstract Four new bent-core mesogens containing biphenyl moieties are reported. All these, except the first homologue, exhibit B7 and B4 banana phases, both of which are known to have a helical structure. The B7 to B4 phase transition is very rare, this being perhaps only the second report of the observation of such a phase sequence. The first homologue exhibits only one mesophase X1 with textural features reminiscent of the B1 phase. All the compounds synthesized are characterized by spectral data. The mesophases exhibited by these compounds are characterized by polarizing optical microscopy, differential scanning calorimetry and X-ray studies.

Tumor Vaccine Design: Concepts, Mechanisms, and Efficacy Testing (1995)

This paper deals with the design of tumor vaccines for either prophylactic application, such as viral vaccines, or for therapeutic application in cancer patients. It discusses important aspects in the design of vaccines which come from experience in the fields of infectious diseases and autoimmunity. As examples of tumor vaccines which are presently being tested, virus-infected tumor cell vaccines and gene-transfected tumor cell vaccines are further discussed. Such live cell vaccines are compared with oncolysate vaccines or vaccines prepared from purified tumor antigens and adjuvants. Future perspectives of such approaches for biotherapy of cancer are also discussed.
Simulation of Microstructural Evolution Based on the Phase-Field Method and Its Applications to Material Development (2009)

The phase-field method has recently been extended and utilized across many fields in materials science. Since this method can systematically incorporate the effect of coherent strain induced by lattice mismatch and applied stress as well as external electric and magnetic fields, it has been applied to many material processes including solidification, solid-state phase transformations and various types of complex microstructure changes. In this paper, firstly the calculation method of phase-field approach is briefly explained. In particular, the basic philosophy of phase-field simulation is mentioned. Secondly, we summarize the recent calculation results of the phase-field simulation of phase transformations in Fe-based alloys and Ni (or Co)-based superalloys. Finally, the image-based calculation of materials properties is explained, where the simulated microstructure image that is the output data of phase-field simulation is employed as a boundary condition for calculating the materials property, and we show the cases of the mechanical property (stress-strain curve), magnetic property (ferromagnetic hysteresis) and electric property (ferroelectric hysteresis) as typical examples of this approach.
Unit Testing, Debugging, and Instruments (2015)

One of the fundamental truths of computer programming (and life) is that not everything works perfectly. No matter how much you plan and no matter how long you’ve been programming, it’s rare for an application you write to work perfectly the first time and then forever under all circumstances and possible uses. Knowing how to properly architect your application and write well-formed code is important. Knowing how to find out why things aren’t working the way they’re supposed to, and fixing them, is equally important.
A Process for the Manufacture of Chemically Produced Toner (CPT). I. Evolution of Structure and Rheology (2005)

A process for the manufacture of chemically produced toner (CPT) has been analyzed using model materials. In part 1 of this two-part paper, the impact of pH and temperature in a Couette-type rheometer and in a combination of two mechanically agitated systems with recirculation between them is reported. The initially stable 100 nm latex suspension at pH ≈ 9 was destabilized by the addition of acid accompanied by vigorous agitation. This destabilization led to the formation of primary aggregates of the original latex suspension of ∼1−2 μm which, at pH < 4, themselves aggregated to give a closely packed paste or gellike structure. This rheologically complex structure had a yield stress and exhibited internal slippage between primary aggregates at certain shearing conditions. The gel was broken by heating to above Tg, the glass-transition temperature, leading to the reformation of aggregates of the primary 1−2 μm latex aggregates of ∼6−12 μm, which could be stabilized by raising the pH again to ∼7. The final near-spherical model CPT product was obtained by heating the 6−12 μm aggregates to ≫Tg to cause internal coalescence. These changes of rheological property and structure and the physicochemical reasons for them are reported in detail.
Characteristic of a PDP-based radiation detector in Xe-He mixture gas (2013)

In this study, we have investigated a 2-dimensional gas detector based on plasma display technology as a candidate for the flat-panel radiation detector. Using the Geant4 and Garfield codes, that simulate the passage of particles through matter, we examined the dependence of X-ray absorption and multiplication factors on the Xe-He gas mixture. Prototype detectors, with four different gas mixtures, were designed and fabricated based on the results from the simulations. The performance of four detectors was evaluated by measuring the collected charge density, dark current density and sensitivity. The maximum collected charge occurred when the Xe 80%-He 20% gas mixture was 1.216 μC/cm2 at -1800 V. The dark current of this detector varied between 0.124 and 0.321 nA/cm2 in the bias range of -300 to -1800 V, which is approximately one-third of the dark current density of an a-Se based detector, in this range. The sensitivity of Xe 80%-He 20% detector was 0.246 nC/mRcm2 at 0.61 V/μm. It is about a tenth lower than that of an a-Se based detector at 10 V/μm.
The heart in limb girdle muscular dystrophy (1998)

10% of these patients had clinically relevant cardiac abnormalities. In autosomal dominant limb girdle muscular dystrophy one subtype characterised by muscle weakness and AV conduction disturbances is recognised. In the course of autosomal recessive/sporadic limb girdle muscular dystrophy, dilated cardiomyopathy may develop, probably related to deficiency of dystrophin associated proteins.
Body posture recognition and turning recording system for the care of bed bound patients (2015)

This paper proposes body posture recognition and turning recording system for assisting the care of bed bound patients in nursing homes. The system continuously detects the patient's body posture and records the length of time for each body posture. If the patient remains in the same body posture long enough to develop pressure ulcers, the system notifies caregivers to change the patient's body posture. The objective of recording is to provide the log of body turning for querying of patients' family members. In order to accurately detect patient's body posture, we developed a novel pressure sensing pad which contains force sensing resistor sensors. Based on the proposed pressure sensing pad, we developed a bed posture recognition module which includes a bed posture recognition algorithm. The algorithm is based on fuzzy theory. The body posture recognition algorithm can detect the patient's bed posture whether it is right lateral decubitus, left lateral decubitus, or supine. The detected information of patient's body posture can be then transmitted to the server of healthcare center by the communication module to perform the functions of recording and notification. Experimental results showed that the average posture recognition accuracy for our proposed module is 92%.
Feasibility of Laser-Induced Breakdown Spectroscopy (LIBS) for Classification of Sea Salts (2012)

We have investigated the feasibility of laser-induced breakdown spectroscopy (LIBS) as a fast, reliable classification tool for sea salts. For 11 kinds of sea salts, potassium (K), magnesium (Mg), calcium (Ca), and aluminum (Al), concentrations were measured by inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and the LIBS spectra were recorded in the narrow wavelength region between 760 and 800 nm where K (I), Mg (I), Ca (II), Al (I), and cyanide (CN) band emissions are observed. The ICP-AES measurements revealed that the K, Mg, Ca, and Al concentrations varied significantly with the provenance of each salt. The relative intensities of the K (I), Mg (I), Ca (II), and Al (I) peaks observed in the LIBS spectra are consistent with the results using ICP-AES. The principal component analysis of the LIBS spectra provided the score plot with quite a high degree of clustering. This indicates that classification of sea salts by chemometric analysis of LIBS spectra is very promising. Classification models were developed by partial least squares discriminant analysis (PLS-DA) and evaluated. In addition, the Al (I) peaks enabled us to discriminate between different production methods of the salts.
Design and Implementation of an Anomaly Detection System: an Empirical Approach (2003)

Network management platforms provide flexible facilities for setting up custom applications able to detect network anomalies on a specific environment. This is because each network is made of users, services and computers with a specific behaviour that is then reflected in the generated network traffic. The goal of this paper is to show that in every network there are some global variables that can be profitably used for detecting network anomalies regardless of the type of network users and equipment. As most of the relations among these variables are fixed, this paper shows that it is possible to define generic network rules aimed to automatically detect network anomalies. Finally, it covers the design and implementation of an application used to validate this work that is freely available on the Internet.
Qa gene expression: biosynthesis and secretion of Qa-2 molecules in activated T cells. (1986)

The biosynthesis and expression of the tissue-specific class I molecule Qa-2 have been studied in resting and activated T-cell populations. Polyclonal activation of T lymphocytes induces a 3- to 4-fold increase in the biosynthesis of Qa-2 molecules but no increase in cell-surface levels. Analysis of the biosynthetic pathway of the Qa-2 molecule in activated lymphocytes reveals that approximately equal to 70% of the newly synthesized Qa-2 molecules are secreted as soluble molecules. In resting-cell populations, Qa-2 remains entirely cell-associated. This process is unique to the Qa-2 molecule, since other class I molecules (e.g., H-2Kb and H-2Db) synthesized by activated cells remain cell-associated. The possibility that the secreted Qa-2 molecule is the product of a new Qa gene or an alternatively spliced mRNA is considered. These results indicate that the Qa-2 molecules may not just function as a cell-surface recognition structure but also may serve a role as a soluble factor synthesized by activated lymphoid cell populations.

Cytotoxic Activities of Several Geranyl-Substituted Flavanones (2010)

Nine geranylated flavanones isolated from the fruits of Paulownia tomentosa (4-12) and two from the roots of Morus alba (13 and 14) were examined for cytotoxicity to selected human cancer cell lines and normal human fibroblasts. Cytotoxicity was determined in vitro using a calcein AM cytotoxicity assay. Cytotoxicity for the THP-1 monocytic leukemia cell line was tested using erythrosin B cell staining. The geranylated compounds tested were compared with the known simple flavanone standards taxifolin (1), naringenin (2), and hesperetin (3) and with the standard anticancer drugs olomoucine II, diaziquone, and oxaliplatin and the antineoplastic compound camptothecin, and showed different levels of cytotoxicity. The effects of structural changes on cytotoxic activity, including geranyl substitution of the flavanone skeleton and the oxidation pattern of ring B of the flavanones, are discussed.
Percentage Points for a Generalized ESD Many-Outlier Procedure (1983)

A generalized (extreme Studentized deviate) ESD many-outlier procedure is given for detecting from 1 to k outliers in a data set. This procedure has an advantage over the original ESD many-outlier procedure (Rosner 1975) in that it controls the type I error both under the hypothesis of no outliers and under the alternative hypotheses of 1, 2, …. k-l outliers. A method is given for approximating percentiles for this procedure based on the t distribution. This method is shown to be adequately accurate using Monte Carlo simulation, for detecting up to 10 outliers in samples as small as 25. Tables are given for implementing this method for n = 25(1)50(10)100(50)500; k = 10, α = .05, .Ol, .005.
Transport and magnetic properties of icosahedral and glassy Pd-U-Si alloys (1986)

The glassy phase of ${\mathrm{Pd}}_{58.8}$${\mathrm{U}}_{20.6}$${\mathrm{Si}}_{20.6}$ alloys can be transformed into an icosahedral quasicrystalline phase by thermal annealing. Electrical transport properties of samples undergoing different degrees of glassy-to-icosahedral phase transformation have been measured. The icosahedral phase has an electrical resistivity of \ensuremath{\sim}220 \ensuremath{\mu}\ensuremath{\Omega} cm at room temperature and a negative temperature coefficient of resistivity. The short electronic mean free path is discussed. At low temperature, the negative magnetoresistivity is attributed to magnetic scattering effects. The low-field ac susceptibility as a function of temperature exhibits a spin-glass-type transition which is not suppressed by a dc magnetic field.
Both Low and High Serum IGF-I Levels Associate with Cancer Mortality in Older Men (2012)

Our findings demonstrate that both low and high serum IGF-I levels are risk markers for increased cancer mortality in older men. Moreover, low IGF-I levels associate with increased CVD mortality.
Type 7 Adenylyl Cyclase is Involved in the Ethanol and CRF Sensitivity of GABAergic Synapses in Mouse Central Amygdala (2011)

The GABAergic system in the central amygdala (CeA) plays a major role in ethanol dependence and in the anxiogenic response to ethanol withdrawal. Previously, we found that both ethanol and corticotropin releasing factor (CRF) increase GABAergic transmission in mouse and rat CeA neurons, in part by enhancing the release of GABA via activation of presynaptic CRF1 receptors. CRF1 receptors are coupled to the enzyme adenylyl cyclase (AC), which produces the second messenger cyclic AMP. There are nine isoforms of AC, but we recently found that CRF1 receptors in the pituitary were coupled to the Type 7 AC (AC7). Therefore, using an in vitro electrophysiological approach in brain slices, here we have investigated a possible role of the AC7 signaling pathway in ethanol and CRF effects on CeA GABAergic synapses of genetically modified mice with diminished brain Adcy7 activity (HET) compared to their littermate male wild-type (WT) mice. We found no significant differences in basal membrane properties, mean baseline amplitude of evoked GABA(A) receptor-mediated inhibitory postsynaptic potentials (IPSPs), or paired-pulse facilitation (PPF) of GABA(A)-IPSPs between HET and WT mice. In CeA neurons of WT mice, ethanol superfusion significantly augmented (by 39%) GABAA-IPSPs and decreased PPF (by 25%), suggesting increased presynaptic GABA release. However, these effects were absent in HET mice. CRF superfusion also significantly augmented IPSPs (by 38%) and decreased PPF (by 23%) in WT CeA neurons, and still elicited a significant but smaller (by 13%) increase of IPSP amplitude, but no effect on PPF, in HET mice. These electrophysiological data suggest that AC7 plays an important role in ethanol and CRF modulation of presynaptic GABA release in CeA and thus may underlie ethanol-related behaviors such as anxiety and dependence.
Remarkable Efficiency in the Catalytic Asymmetric Epoxidation of (<i>E</i>)-3-Trimethylsilyl-2-propen-1-ol (1991)

The Sharpless epoxidation of (E)-3-trimethylsilyl-2-propen-1-ol (3) affords the corresponding epoxide 4 [(2S,3S)-2, 3-epoxy-3-trimethylsilylpropan-1-ol] in 99% enantiomeric excess in the presence of only 3 mol% of the catalyst (Ti(Oi-Pr)4/L-(+)-diisopropyl tartrate). The epoxide 4 is further converted into various (S)-glycidol [(S)-2, 3-epoxypropan-1-ol] derivatives with retention of optical purity.
Cisplatin-associated hemolytic-uremic syndrome. Successful treatment with a staphylococcal protein A column (1989)

Cisplatin-associated hemolytic-uremic syndrome (HUS), an under-reported form of HUS induced by chemotherapy, typically pursues a fulminant and lethal course. We report the cases of two patients with squamous cell carcinoma of the head and neck who developed massive hemolysis, profound thrombocytopenia, and dialysis-dependent renal failure after therapy with cisplatin. Plasma exchange was ineffective in both patients, but plasma perfusion with a staphylococcal protein A column produced a dramatic and permanent response in the second patient. These cases show the importance of considering HUS as a cause of renal failure in such patients who receive cisplatin-based chemotherapy, and support the role of staphylococcal protein A plasma perfusion as treatment for this condition.
Using portable device sensors to recognize height changing modes of motion (2014)

In portable navigation, the need to recognize the motion mode of the user, is useful - if not necessary - to improve the positioning estimation. This paper explains the use of sensors in a portable device, such as a smartphone, to recognize the user's mode of motion when a change in height is detected. The modes of motion detected are walking up or down stairs, taking the elevator, and standing or walking on an escalator. The portable device contains an accelerometer triad, gyroscope triad, a barometer, and occasionally a magnetometer triad. The solution is dependent on the sensors, and does not require satellite or wireless positioning. The height motion mode recognition module has been implemented in real-time on several brands of various consumer portable devices, including smartphones, tablets, smartwatches, and smart glasses.
