Hybrid Precoding&#x002F;Combining Design in mmWave Amplify-and-Forward MIMO Relay Networks (2019)

In this paper, we consider the amplify-and-forward relay networks in mmWave systems and propose a hybrid precoder/combiner design approach. The phase-only RF precoding/combining matrices are first designed to support multi-stream transmission, where we compensate the phase for the eigenmodes of the channel. Then, the baseband precoders/combiners are performed to achieve the maximum mutual information. Based on the data processing inequality for the mutual information, we first jointly design the baseband source and relay nodes to maximize the mutual information before the destination baseband receiver. The proposed low-complexity iterative algorithm for the source and relay nodes is based on the equivalence between mutual information maximization and the weighted MMSE. After we obtain the optimal precoder and combiner for the source and relay nodes, we implement the MMSE-SIC filter at the baseband receiver to keep the mutual information unchanged, thus obtaining the optimal mutual information for the whole relay system. Simulation results show that our algorithm achieves better performance with lower complexity compared with other algorithms in the literature.

Rational Design of Rhodium–Iridium Alloy Nanoparticles as Highly Active Catalysts for Acidic Oxygen Evolution (2019)

The oxygen evolution reaction (OER) is pivotal for renewable energy conversion and storage devices, such as water electrolyzers and rechargeable metal-air batteries. However, the rational design of electrocatalysts with suitably high efficiencies and stabilities in strongly acidic electrolytes remains a significant challenge. Here, we show the demonstration of sub-10 nm, composition-tunable Rh-Ir alloy nanoparticles (NPs) prepared using a scalable microwave-assisted method as superior acidic OER catalysts. The OER activities showed a volcano-shaped dependence on Ir composition, with Ir-rich NPs (Ir ≥ 51%) achieving better OER performance than pure Ir NPs, as reflected by lower overpotentials and higher mass activities. Most significantly, Rh<sub>22</sub>Ir<sub>78</sub> NPs achieved a maximum mass activity of 1.17 A mg<sup>-1</sup><sub>Ir</sub> at a 300 mV overpotential in 0.5 M H<sub>2</sub>SO<sub>4</sub>, which corresponds to a 3-fold enhancement relative to pure Ir NPs, making it one of the most active reported OER catalysts under acidic conditions. Density functional theory calculations reveal that owing to the synergy of ensemble and electronic effects by alloying a small amount of Rh with Ir, the binding energy difference of the O and OOH intermediates is reduced, leading to faster kinetics and enhanced OER activity. Furthermore, Rh-Ir alloy NPs demonstrated excellent durability in strongly acidic electrolyte. This work not only provides fundamental understandings relating to composition-electrochemical performance relationships but also represents the rational design of highly efficient OER electrocatalysts for applications in acidic media.
Incessant monomorphic ventricular tachycardia associated with pneumococcal meningitis: a case report. (2007)

A 22-year-old man with incessant ventricular tachycardia (VT) associated with pneumococcal meningitis without obvious heart disease manifesting as febrile sensation and severe headache visited our emergency department. Initial electrocardiography showed ventricular premature couplets, but the rhythm grew more serious and developed into incessant monomorphic VT resulting in an electrical storm. After examining the cerebrospinal fluid, bacterial meningitis was suspected. The electrical storm ended 21 hr after he had received conservative treatment for meningitis. Streptococcus pneumonia was cultured from the cerebrospinal fluid. No VT was observed during the remainder of the hospital stay and could not be induced in the electrophysiological study.
A Scriptable, Statistical Oracle for a Metadata Extraction System (2007)

An oracle is described for dynamic validation of an application (metadata extraction from scanned documents) where a moderate failure rate is acceptable provided that instances of failures during operation can be identified. The oracle combines a variety of deterministic tests and statistical tests based upon characteristics of the document collection on which the system operates. Because this system must adapt to a variety of document collections with different characteristics, a scripting language is developed that binds combinations of tests to the metadata fields expected in a given document collection. The suitability of the oracle is demonstrated by an experiment measuring its ability to mimic human judgments as to which of several alternate outputs for the same document would be preferred.
Nanosecond time scale transient optoplasmonic detection of single proteins (2022)

Optical detection of individual proteins with high bandwidth holds great promise for understanding important biological processes on the nanoscale and for high-throughput fingerprinting applications. As fluorescent labels impose restrictions on detection bandwidth and require time-intensive and invasive processes, label-free optical techniques are highly desirable. Here, we read out changes in the resonantly scattered field of individual gold nanorods interferometrically and use photothermal spectroscopy to optimize the experiment’s parameters. This interferometric plasmonic scattering enables the observation of single proteins as they traverse plasmonic near fields of gold nanorods with unprecedented temporal resolution in the nanosecond-to-microsecond range.
G-quadruplex formation of entirely hydrophobic DNA in organic solvents (2013)

We report herein a novel hydrophobic G-quadruplex DNA consisting of dodecyl phosphotriester linkages. The 6-mer hydrophobic DNA having a TG4T sequence binds to monovalent cations to form a tetramolecular G-quadruplex in low polarity organic solvents.
Psyllid Biology: Expressed Genes in Adult Asian Citrus Psyllids, Diaphorina citri Kuwayama (2009)

Where it occurs the Asian citrus psyllid, Diaphorina citri, Kuwayama (Hemiptera: Psyllidae) is considered the primary vector of Huanglongbing, HLB, disease of citrus trees. The plant pathogenic bacterium associated with HLB causes economic losses to citrus industries worldwide. To better understand the general biology of D. citri, we undertook a sequencing project from adult psyllids. Few genes have been isolated from psyllids however several insect genomic datasets are available for comparisons. We compared the psyllid data to genomic datasets of nematode, C. elegans, fruit fly, D. melanogaster, honey bee, A. mellifera, mosquito, A. aegypti, and human, H. sapiens since these have completed more thorough levels of annotation. We describe the first data set of ESTs from D. citri, the Asian citrus psyllid. A total of 5,906 cDNA clones were sequenced, resulting in 4,595 high-quality ESTs. Electronic removal of 1,487 sequences which matched to bacteria and viruses left an assembly of cDNAs resulting in a total of 636 psyllid sequences (544 contigs plus 92 singlets). The sequences underwent BLAST analyses using (Swissprot-Tremble 03-2007) and NCBI, nr databases which returned 53% with 'No significant match' in either the non-redundant protein or nucleic acid databases, providing new information to the scientific community. The D. citri gene expression data set advances current research efforts in the identification of genes and physiological processes of psyllids. Knowledge of these genes and proteins are being used in the development of novel management strategies against psyllids, and other sap feeding insects within the Order: Hemiptera.
Collective construction using Lego robots (2006)

Management options for carotid stenosis include medical management, carotid endarterectomy, carotid stenting with distal filter protection, or stenting with either flow arrest or flow reversal techniques.1 Flow reversal with transcarotid artery revascularization (TCAR) technique represents a hybrid approach with surgical access to the common carotid for endovascular placement of a stent in the internal carotid artery. This direct access to the carotid artery avoids navigating the challenging anatomy of the aortic arch with endovascular devices.2 Compared to transfemoral stenting, TCAR possesses lower risk of transient ischemic attack and stroke, and compared to carotid endarterectomy, there is less risk of cranial neuropathy.3,4 We present the case of an 87-yr-old man with recurrent severe stenosis (85%) of the right internal carotid artery. The patient had a remote history of bilateral endarterectomies for asymptomatic stenosis and was found with recurrence and progression of right internal carotid artery stenosis. Options were discussed and decision was made to proceed with TCAR after he consented for the procedure. The patient tolerated the procedure well with satisfactory revascularization. Exam remained unremarkable prior to discharge on postoperative day 1 and during follow-up at 1 mo. Patient consented to the publication of their image.
[Changes in some properties of 3':5'-AMP-dependent protein kinase from rat skeletal muscles during physical exercise]. (1981)

During 6-week training of rats the activity of isoenzymes I and II of soluble 3':5'-AMP-dependent protein kinase increases by 22 and 33%, respectively. A long-term physical load does not cause any significant changes in the activity of both isoenzymes. The maximal activity of the isoenzymes from skeletal muscles of the control and experimental rats is observed at the same concentrations of 3':5'-AMP and pH of 6,0-6,5. During training and under physical load the apparent Km values for ATP of both isoenzymes of 3':5'-AMP-dependent protein kinase do not change significantly, whereas that of V shows an increase. The apparent Km and V values for the histone increase for isoenzyme I obtained from skeletal muscles of trained rats both at rest and under physical load. In case of isoenzyme II the Km value for the histone decreases, while that of V remains unchanged. The changes in the properties of isoenzymes I and II of 3':5'-AMP-dependent protein kinase from skeletal muscles suggest the participation of the enzyme in adaptation to systematic muscular activity.

Bunolol Metabolism by Cell-Free Preparations of Human Liver: Biosynthesis of Dihydrobunolol (1972)

1. Cell-free preparations from human liver taken at autopsy were used to biosynthesize a metabolite from bunolol. The metabolite was isolated and identified as dihydrobunolol on the basis of elemental analysis, n.m.r., i.r. and u.v. spectrometry, and inability to form a 2,4-dinitrophenylhydrazone.2. The identification was confirmed by the subsequent synthesis of dihydrobunolol and comparative studies including t.l.c., n.m.r., i.r. and u.v. spectrometry.3. The livers of ten cadavers contained the reductase which was located in the cytosol. The enzyme utilized NADPH more effectively than NADH. At a higher pH, the same liver fraction extensively converted dihydrobunolol to bunolol.4. Synthetic dihydrobunolol was as active as bunolol in antagonizing isoproterenol-induced changes in blood pressure, heart rate and contractile force after intravenous administration to the dog.

Preoperative demonstration of postinflammatory syringomyelia. (1983)

Syringomyelia secondary to arachnoiditis is a rarely reported entity, which has not been described in the radiographic literature. A series of eight patients who had either postinfectious, posthemorrhagic, iatrogenic, or idiopathic arachnoiditis was examined recently with metrizamide computed tomography (CT). These patients presented with progressive neurologic deficits that could not be attributed to the level of arachnoid changes on myelography. On immediate and/or delayed CT scans, metrizamide accumulation within the central part of the cord was identified, both at and above the level of the arachnoiditis. In some patients, the cord diameter was normal. Syrinx cavities were demonstrated and shunted at surgery with subsequent partial relief or arrest of the symptoms. The mechanism of development of postinflammatory syringomyelia is discussed.
Amino-steroids. Part I. 16-Piperidino- and 16-morpholino-androstanes and -œstra-1,3,5(10)-trienes (1966)

The preparation of 16β-piperidino- and -morpholino-17-ketones of C18- and C19-steroids from 16α-bromo-17-ketones is described; reduction gives the corresponding cis-16β-amino-17β-ol the structure of which is confirmed by preparation from the trans-16α-bromo-17β-ol and by infrared spectroscopy. trans-16-Amino-17ols were prepared from cis-16-bromo-17-ols and a 16α,17α-epoxide.

Simulation off Fluid Flow in Hydraulic Fracturing: Implications for 3D Propagation (1990)

Summary A formulation for simulating arbitrarily shaped 3D fractures is presented. The technique extends previous variational techniques and provides a stable solution with a minimum number of elements. The model is used to assess the applicability of simplified height-growth models. Issues related to the treatment of 2D convection fields, associated with the fluid-flow equations, are also addressed.
Developmental effects of neonatal fractionated co‐exposure to low‐dose gamma radiation and paraquat on behaviour in adult mice (2018)

Radiological methods for screening, diagnostics and therapy are often used in healthcare; however, it has recently been reported that developmental exposure to low-dose ionizing radiation (IR) causes neurotoxicity. Environmental chemicals also have the potential to affect the developing brain and the concomitant effects caused by IR and chemicals are of high interest today. We therefore aim to investigate if low-dose IR can interact with the known neurotoxicant paraquat to induce neurotoxicity in the neonatal mouse model. Using the same model, we also aim to investigate if fractionated low-dose IR can be as neurotoxic as higher acute doses. Male mice were exposed to a single dose of paraquat (0.2 or 0.02 mg/kg) on postnatal day 10 and 11. Two hours following paraquat exposure, mice were whole body irradiated with 100 or 300 mGy gamma radiation (<sup>137</sup> Cs). Behavioural observations were performed at 2 and 3 months of age. Following behavioural testing, we evaluated striatal dopaminergic gene transcription. Animals co-exposed to IR and paraquat generally displayed altered spontaneous behaviour compared to controls and single agent exposed mice. Stronger effects by combined exposure were also observed on adult memory and learning. However, dopaminergic gene transcript levels remained unchanged by treatment. Co-exposure to low-dose IR and paraquat can interact to exacerbate neurotoxic effects and to impair cognitive function. Furthermore, fractionation of the radiation dose was observed to be as potent as higher acute exposure for induction of developmental neurotoxicity.
Laser interferometric vibration measurements of the middle ear in healthy humans (1996)

The use of spontaneous and evoked otacoustic emissions is now a standard clinical tool for diagnosis of the function of the inner ear. However, it is not possible to extract this information over the entire, functionally relevant frequency range because of imperfect coupling of: (1) stapedial to ear-drum vibrations through the ossicular chain of the middle ear and (2) ear-drum vibrations to air in the external auditory meatus. The problem could be circumvented if it were possible to measure the vibration of the stapes and ear drum. The ear drum can be visualized non-invasively, whereas the stapes is only accessible intra-operatively. Therefore, we designed a laser-interferometric system to non-invasively measure the vibration of the human ear drum. Vibrations were measured with a laser Doppler velocimeter (Polytec OFV-302) coupled into the side arm of an operating microscope (Zeiss OPMI MDM). The wavelength was 633 nm and emitted power was less than 1 mW. Direct coupling through the optics of the operating microscope, instead of through glass fibers, enabled a larger signal-to- noise ratio (20 - 30 dB) due to collection of more reflected light. This coupling scheme avoids the problems associated with having to place a reflecting material on the ear drum. The developed vibration measurement system allows non-invasive, fast and reproducible characterization of the dynamics of the human ear drum and as such can be used for clinical diagnostics.
Selective Inhibition of Aggregation and Toxicity of a Tau‐Derived Peptide using Its Glycosylated Analogues (2016)

Protein glycosylation is a ubiquitous post-translational modification that regulates the folding and function of many proteins. Misfolding of protein monomers and their toxic aggregation are the hallmark of many prevalent diseases. Thus, understanding the role of glycans in protein aggregation is highly important and could contribute both to unraveling the pathology of protein misfolding diseases as well as providing a means for modifying their course for therapeutic purposes. Using β-O-linked glycosylated variants of the highly studied Tau-derived hexapeptide motif VQIVYK, which served as a simplified amyloid model, we demonstrate that amyloid formation and toxicity can be strongly attenuated by a glycan unit, depending on the nature of the glycan itself. Importantly, we show for the first time that not only do glycans hinder self-aggregation, but the glycosylated peptides are capable of inhibiting aggregation of the non-modified corresponding amyloid scaffold.
Linear and Semicyclic Amphiphilic Diblock Copolymers. 1. Synthesis and Structural Characterization of Cyclic Diblock Copolymers of Poly(hydroxyethyl vinyl ether) and Linear Polystyrene and Their Linear Homologues (1996)

We recently proposed a new method allowing the controlled synthesis of ring-shaped polymers with predictable molar masses and narrow molar mass distribution. The cyclization is based on a unimolecular “end-to-end” coupling reaction of an heterodifunctional linear polymer precursor. In this paper, this methodology is applied to the synthesis of semicyclic block copolymers comprising a cyclic hydrophilic block on which a linear hydrophobic polymeric tail is attached, i.e., a cyclic diblock copolymer of poly(hydroxyethyl vinyl ether) and linear polystyrene. The general strategy for the synthesis involves three main steps: (i) preparation of a linear α-acetal-γ-styrenyl-poly(chloroethyl vinyl ether-block-styrene) precursor, (ii) intramolecular coupling involving the activation and reaction of the two complementary functions under high dilution, yielding the cyclized poly(CEVE) block, and (iii) substitution by hydroxy functions of the chloro side groups of poly(CEVE) block in order to form the amphiphilic semicyclic diblock copolymer. The corresponding linear diblock copolymer, with the same block length, n, and molar mass distribution, was simultaneously obtained using steps i and iii. The synthesis and characterization of these new diblock copolymers of controlled dimensions is described.
Possibility of Harvesting June-bearing Strawberries in a Plant Factory with Artificial Light during Summer and Autumn by Re-using Plants Cultivated by Forcing Culture (2021)

The aim of this study was clarifying whether the strawberry plants used for forcing cultivation could be stored and continuously cultivated in a plant factory with artificial light (PFAL). Forced June-bearing strawberries were harvested from November to May in Japan. In this study, we transferred the forced June-bearing strawberries to a PFAL in late April, and examined the differences in flowering and yield, and the effects of lighting conditions on flowering, yield, and leaf photosynthesis. We observed continuous flowering and fruit development through August, in low-temperature (20℃ in light and 10℃ in dark) and short-day (8-hour day length) treatment, and medium-temperature (25℃ in light and 15℃ in dark) and medium-day (12-hour day length) treatment. The prolific“Benihoppe”and“Akihime”cultivars had high yields from May to October. Furthermore,“Benihoppe”showed significantly higher photosynthetic rate under strong light (Photosynthetic Photon Flux Density (PPFD) of 510±12 μmol m-2 s-1) than under weak light (PPFD of 301.5±30.5 μmol m-2 s-1). The study suggests that the productive lives of June-bearing strawberry plants, which were usually discarded in commercial farms in mid-May, could be extended for up to 5 months (Jun. – Oct.) by transferring them to a PFAL.
