Cross-Correlation Analysis of After Emotional Stimulation in EEG Using a Smartphone (2021)

[Objective] The purpose of this study was to investigate the information processing process in the brain by cross-correlation analysis of brain waves after emotional stimulation with a smartphone. [Methods] The subjects were 23 healthy adults that were divided into two groups, namely stress and non-stress groups, via psychological examination. In the experiment, stimuli of relaxation, pleasant, unpleasant, pleasant sentence, and unpleasant sentence were displayed on a smartphone for the subject, and the brain waves were measured concurrently. To record the EEG data, the electrodes (19 channels) were placed according to the international 10/20 system. Coherence analysis was performed on the EEG, and the coherence values and time lag in 171 combinations among all channels in the alpha 1 band (8–10 Hz) were calculated. [Results] The time-lag between unpleasant, pleasant, and unpleasant sentences in the non-stress group was higher than that for the rest and pleasant stimuli. The stress group showed higher time-lag than the non-stress group at all stimulation times. [Discussion] The results imply that the stress group has slower information propagation compared to the non-stress group. Additionally, it can be suggested that text stimulation received from a smartphone has slow information propagation, regardless of its content.
Rewritable digital data storage in live cells via engineered control of recombination directionality (2012)

The use of synthetic biological systems in research, healthcare, and manufacturing often requires autonomous history-dependent behavior and therefore some form of engineered biological memory. For example, the study or reprogramming of aging, cancer, or development would benefit from genetically encoded counters capable of recording up to several hundred cell division or differentiation events. Although genetic material itself provides a natural data storage medium, tools that allow researchers to reliably and reversibly write information to DNA in vivo are lacking. Here, we demonstrate a rewriteable recombinase addressable data (RAD) module that reliably stores digital information within a chromosome. RAD modules use serine integrase and excisionase functions adapted from bacteriophage to invert and restore specific DNA sequences. Our core RAD memory element is capable of passive information storage in the absence of heterologous gene expression for over 100 cell divisions and can be switched repeatedly without performance degradation, as is required to support combinatorial data storage. We also demonstrate how programmed stochasticity in RAD system performance arising from bidirectional recombination can be achieved and tuned by varying the synthesis and degradation rates of recombinase proteins. The serine recombinase functions used here do not require cell-specific cofactors and should be useful in extending computing and control methods to the study and engineering of many biological systems.
Somatostatin in the control of respiration (1988)

Somatostatin has been found to induce apnoea when applied into the brain ventricular system (Fuxe et al . 1982, Härfstrand et al . 1985). The site of action of somatostatin was suggested to be in the dorsal respiratory neurons in the medulla oblongata of the rat (Fuxe et al . 1982) where high somatostatin‐like immunoreactivity has been detected (Kalia et al . 1984a). In the present study we wanted to further localize the site(s) of action of somatostatin on respiration by microinjection of somatostatin into the medulla oblongata of the cats. We could not detect any inhibitory effect of somatostatin on respiration after microinjection into the nuclear complex of the solitary tract. On the other hand microinjection of somatostatin into the region of nucleus paragigantocellularis lateralis consistently caused apnoea. This finding further supports the idea that this structure functions as an integrative area of respiratory drive inputs.
Antibiotic-Impregnated Autogenic Cancellous Bone Grafting Is an Effective and Safe Method for the Management of Small Infected Tibial Defects: A Comparison Study (2000)

After 4 to 6 years of follow-up, our results suggest that the use of impregnating antibiotics have no adverse effects on autogenic cancellous bone graft incorporation and could help to eliminate infection effectively.
Silicon nanowire array/Cu2O crystalline core–shell nanosystem for solar-driven photocatalytic water splitting (2013)

P-type Cu2O nanocrystals were deposited on n-type silicon nanowire arrays (Si NWs) to form core-shell heterojunction arrays structure via a simple electroless deposition technique. Scanning electron microscopy, transmission electron microscope and x-ray diffraction were utilized to characterize the morphology and structure of the core-shell nanosystem. The reflectivity of the obtained core-shell structure measured by UV/vis spectrometry showed a comparatively low reflectivity in the visible-light region, which implied good optical absorption performance. The water splitting performance of the obtained Si NWs, planar Si/Cu2O structure and Si NW/Cu2O core-shell nanosystem were studied. Owing to the large specific surface area, heterojunctions formed between Cu2O nanocrystallites and Si NWs and the light trapping effect of the NW array structure, the photocatalytic performance of the Si NW/Cu2O core-shell nanosystem increased markedly compared with that of pure silicon NWs and a planar Si/Cu2O structure, which means excellent hydrogen production capacity under irradiation with simulated sunlight. In addition, the photocatalytic performance of the core-shell nanosystem was improved obviously after platinum nanoparticles were electrodeposited on it.

The Role of the Minor Groove Substituents in Indirect Readout of DNA Sequence by 434 Repressor (2003)

The sequence of non-contacted bases at the center of the 434 repressor binding site affects the strength of the repressor-DNA complex by influencing the structure and flexibility of DNA (Koudelka, G. B., and Carlson, P. (1992) Nature 355, 89-91). We synthesized 434 repressor binding sites that differ in their central sequence base composition to test the importance of minor groove substituents and/or the number of base pair hydrogen bonds between these base pairs on DNA structure and strength of the repressor-DNA complex. We show here that the number of base pair H-bonds between the central bases apparently has no role in determining the relative affinity of a DNA site for repressor. Instead we find that the affinity of DNA for repressor depends on the absence or presence the N2-NH(2) group on the purine bases at the binding site center. The N2-NH(2) group on bases at the center of the 434 binding site appears to destabilize 434 repressor-DNA complexes by decreasing the intimacy of the specific repressor-DNA contacts, while increasing the reliance on protein contacts to the DNA phosphate backbone. Thus, the presence of an N2-NH(2) group on the purines at the center of a binding site globally alters the precise conformation of the protein-DNA interface.
Molecular cloning and expression of an inwardly rectifying K(+) channel from bovine corneal endothelial cells. (2000)

Corneal endothelial cells express IRK1 (Kir2.1) inwardly rectifying K(+) channels. Consistent with the properties of IRK1 channels, BCIRK1 is likely involved in regulating membrane potential and possibly other cellular functions in corneal endothelial cells.
The Effect of a Disposable Probe Cover on Pulse Oximetry (2002)

The re-use of pulse oximeter probes presents the possibility of between-patient contamination. Use of a disposable polyethylene cover may reduce this risk. In a controlled, prospective study we examined the effect of such a cover on the accuracy of pulse oximetry. Each of ten volunteer subjects was monitored simultaneously by two identical Nellcor pulse oximeters, one with a plastic cover and the other, without a cover, used as a control. The pulse oximetry (SpO2) reading for each probe was recorded while subjects breathed 21% O2 and again while they breathed 10% O2. The probe cover was then swapped onto the other probe and the recordings were repeated. Ninety-five per cent limits of agreement in SpO2 (mean difference in SpO2 (1.95 x standard deviation of difference) between covered and non-covered probes were -0.6% to 0.6% while breathing 21% oxygen and -2.0% to 2.9% while breathing 10% oxygen. We conclude that a protective plastic sheath may induce a small error in pulse oximetry reading that is most marked during hypoxaemia. This error is unlikely to be of clinical significance.
Towards high performance green piezoelectric generators based on electrochemically poled nanocellulose (2022)

Abstract Internet-of-everything (IoE) is defined as networked connections of things, people, data and processes. IoE nodes, preferably shaped as printed flexible systems, serves as the frontier outpost of the Internet and comprises devices to record and regulate states and functions. To power distributed IoE nodes in an ecofriendly manner, technology to scavenge energy from ambience and self-powered devices are developed. For this, piezoelectricity is regarded as a key-property, however current technology typically based on polyvinylidene difluoride (PVDF) co-polymers, are expensive and produced via toxic protocols. We report piezoelectric characteristics of electrochemically poled cellulose nanofiber (CNFs) thin films processed from water dispersions. Poling these films at humid conditions cause breaking and reorientation of CNF segments, which results in enhanced crystal alignment rendering the resulting material piezoelectric. Generators based on poled CNF show similar piezoelectric voltage and coefficient, here measured to d 33 = 46 pm/V, as for devices including PVDF copolymer layers of similar thickness. Our findings promise for low cost and printable ecofriendly piezoelectric-powered IoE nodes.
Gastroschisis: A gene–environment model involving the VEGF–NOS3 pathway (2008)

Gastroschisis is a severe major malformation in which an infant is delivered with a portion of intestines and possible other abdominal organs extruding through a defect in the abdominal wall, usually to the right of the umbilical cord. Etiologies of gastroschisis are largely unknown, and even its pathogenesis is poorly understood. Several recent epidemiological studies have identified interactions between maternal smoking during pregnancy, genetic variants of endothelial nitric oxide synthase, and risk for gastroschisis. We present a brief review of the endothelial nitric oxide synthase pathway and its relationship to vasculogenesis, suggesting that disruption of this pathway by environmental exposures or by genetic variation may represent one pathogenetic model for gastroschisis.
Supervised learning from multiple experts (2009)

We describe a probabilistic approach for supervised learning when we have multiple experts/annotators providing (possibly noisy) labels but no absolute gold standard. The proposed algorithm evaluates the different experts and also gives an estimate of the actual hidden labels. Experimental results indicate that the proposed method is superior to the commonly used majority voting baseline.

Abstract
Resonant-type optical modulator with double-stub structure (2002)

We investigated a resonant-type Mach-Zehnder optical modulator consisting of planar structures, designed to overcome the problems of making such a device and to increase the efficiency of the optical modulation. the electrode structure consists of modulating electrode and two stubs. The modulating electrode has two arms of the same length, and is an asymmetric coplanar waveguide.
The circadian oscillator in Synechococcus elongatus controls metabolite partitioning during diurnal growth (2015)

Synechococcus elongatus PCC 7942 is a genetically tractable model cyanobacterium that has been engineered to produce industrially relevant biomolecules and is the best-studied model for a prokaryotic circadian clock. However, the organism is commonly grown in continuous light in the laboratory, and data on metabolic processes under diurnal conditions are lacking. Moreover, the influence of the circadian clock on diurnal metabolism has been investigated only briefly. Here, we demonstrate that the circadian oscillator influences rhythms of metabolism during diurnal growth, even though light-dark cycles can drive metabolic rhythms independently. Moreover, the phenotype associated with loss of the core oscillator protein, KaiC, is distinct from that caused by absence of the circadian output transcriptional regulator, RpaA (regulator of phycobilisome-associated A). Although RpaA activity is important for carbon degradation at night, KaiC is dispensable for those processes. Untargeted metabolomics analysis and glycogen kinetics suggest that functional KaiC is important for metabolite partitioning in the morning. Additionally, output from the oscillator functions to inhibit RpaA activity in the morning, and kaiC-null strains expressing a mutant KaiC phosphomimetic, KaiC-pST, in which the oscillator is locked in the most active output state, phenocopies a ΔrpaA strain. Inhibition of RpaA by the oscillator in the morning suppresses metabolic processes that normally are active at night, and kaiC-null strains show indications of oxidative pentose phosphate pathway activation as well as increased abundance of primary metabolites. Inhibitory clock output may serve to allow secondary metabolite biosynthesis in the morning, and some metabolites resulting from these processes may feed back to reinforce clock timing.
Peptide‐Induced Hierarchical Long‐Range Order and Photocatalytic Activity of Porphyrin Assemblies (2014)

Abstract Long‐range structural order and alignment over different scales are of key importance for the regulation of structure and functionality in biology. However, it remains a great challenge to engineer and assemble such complex functional synthetic systems with order over different length scales from simple biologically relevant molecules, such as peptides and porphyrins. Herein we describe the successful introduction of hierarchical long‐range order in dipeptide‐adjusted porphyrin self‐assembly by a thermodynamically driven self‐orienting assembly pathway associated with multiple weak interactions. The long‐range order and alignment of fiber bundles induced new properties, including anisotropic birefringence, a large Stokes shift, amplified chirality, and excellent photostability as well as sustainable photocatalytic activity. We also demonstrate that the aligned fiber bundles are able to induce the epitaxially oriented growth of Pt nanowires in a photocatalytic reaction.

Genomic biomarkers in prostate cancer (2018)

Prostate cancer is the most common non-cutaneous cancer among men in the United States. In the last decade there has been a rapid expansion in the field of biomarker assays for diagnosis, prognosis, and treatment prediction in prostate cancer. The evidence base for these assays is rapidly evolving. With several commercial assays available at each stage of the disease, deciding which genomic assays are appropriate for which patients can be nuanced for physicians. In an effort to help guide these decisions in clinical practice, we aim to give an update on the current status of the biomarker field of prostate cancer.
U.S. Department of Energy: Green Energy Efficiency Spruces Budget Practices (2013)

The U.S. Department of Energy (DOE) oversees the United States’ energy-related affairs. The department prepares an annual budget by evaluating its fiscal position: the amount of federal funds it received each of the last three to five years, its expenditures’ relationship to these appropriations, and the factors causing its financial situation. Then, since the recent sequestration reduced departments’ federal appropriations, the DOE must critically prioritize its most effective programs and amend or terminate others. This paper’s format follows this budgeting process and analyzes four policies’ costs and benefits. The findings suggest the department recommend that Congress retain or reinstate enhanced loan guarantee programs, strengthen and reestablish the advanced energy manufacturing tax credit, maintain and fortify the renewable energy production tax credit, and eliminate the three to eight costliest fossil fuel tax expenditures for companies whose revenues surpass a defined threshold.
Challenging Treatment of a Secondary Endoleak in a Fenestrated Endograft (2010)

Treatment of a secondary type I endoleak after implantation of a fenestrated endoprosthesis is challenging. The novel use of an Amplatzer occluder in this setting may be applicable to other situations in which an endovascular solution is desirable for complications of complex endovascular aneurysm repair.
An Energy Efficient Multi-Core Modem Architecture for LTE Mobile Terminals (2012)

Since data rate in wireless communication systems has exponentially increased during the last decade, serious efforts are considered to fulfill their target requirements. Therefore, providing a satisfactory hardware to support high data rates while minimizing power consumption is a key design challenge for Long Term Evolution (LTE) mobile terminals. In this paper we introduce an optimized parallel software architecture for LTE mobile terminals using an energy aware scheduling and load balancing. We show that the proposed software architecture on single, dual, triple and quad-core hardware platforms leads to up to 39% energy savings. In addition, different hardware design options are investigated in order to minimize the average power consumption. The homogeneous multi-core with four cores processing the optimized LTE software saves about one quarter of the energy compared to a single-core running at higher clock frequency achieving the same data rate. Considering statistics for the mobile user behavior, the homogeneous multi-core with four cores proves to provide the minimum average power consumption compared to the other hardware architectures considered in this work.
New high-speed bipolar XOR gate with absolutely symmetrical circuit configuration (1990)

A new monolithic integrated exclusive OR gate (XOR) in E2CL circuit design is presented. The symmetry with respect to both inputs makes it superior to the standard XOR gates in ECL or E2CL for several applications. The circuit was realised using a conservative 2 μm standard silicon bipolar technology.
Reproduction of acute bracken poisoning in a calf with ptaquiloside, a bracken constituent (1984)

Acute bracken fern toxicity in a calf was reproduced with ptaquiloside, a norsesquiterpene glucoside, isolated from the boiling water extract of bracken fern. Ptaquiloside was dissolved in 500 ml of saline and administered by drench at increasing dosages for six days out of every seven for the following periods: 400 mg/day for 24 days, 800 mg/day for 14 days and 1600 mg/day for four days. Neutrophilic granulocytes began to decrease markedly around 50 days after the start of the experiment, and granulocytopenia continued for a further 35 days until the autopsy, despite the discontinuance of ptaquiloside administration. Thrombocytes showed a relatively slow depression and reached 1 X 10(5)/mm3 at the lowest level. The calf was autopsied 86 days after the start of administration of ptaquiloside. Sternal bone marrow was found to be mostly replaced with fat marrow and only small foci of erythropoietic cells and a small number of megakaryocytes remained.
Range Finding and Surface Characterization Using High-Frequency Air Transducers (1987)

The design and applications of high-frequency piezoelec- tric air transducers are described. Two types of thickness mode air transducers are designed and fabricated using newly synthesized acoustic matching layers with an acoustic impedance as low as 0.3 Mrayls. The insertion losses of these transducers are improved by 32- 45 dB compared to that of the transducer without a matching layer. Use of a l-MHz double matching layer transducer with a good RF pulse response for range finding has revealed that the measurement range accuracy is of the order of 0.1 mm. For surface profile and defect mea- surements of solid objects, a focused transducer with a single matching layer is found suitable due to its small focal spot diameter of 1.3 mm and range accuracy of 0.1 mm. Other applications described here are the analysis of a cloth surface state using the acoustic signals propa- gating along the cloth surface and passing through the cloth. air transducers mentioned above. This paper describes the design of these transducers and their applications to range finding, profile measurement of solid objects, and surface state measurement of cloth.
