Multi-static MIMO-SAR three dimensional deformation measurement system (2015)

Herein is proposed a novel high-steep rock slope landslide monitoring system based on the configuration of multi-static multiple-input multiple-output synthetic aperture radar (MIMO-SAR). In this system, three spastically distributed radars are employed. Each is a Ku-band MIMO-SAR, transmitting mutually orthogonal waveforms and sensing the slope movement from different view angles. The three radars can then achieve the deform measurements in the three line of sight (LOS) directions. After an effective fusion of these measurements, the deform vector, with direction and amount, can be resolved. This vector is particularly important for risk warning as well as for understanding the motion mechanism of landslide. Moreover, the data acquisition period can be largely reduced, since the use of MIMO radar allows a simultaneous sampling of the scene echo. The time decorrelation is therefore very small, and hence high measurement accuracy can be expected. It can be proved that, using this system, the three-dimensional accuracy can reach 0.1 ~ 1 mm. Simulations and experimental datasets are used to validate this proposal.
Femoral Neck Fracture Risks in Spinal Cord Injury Patients (1999)

Methods: Bone mineral density(BMD)of right femoral necks(RFN)in 50 young male spinal cord injury(SCI)patients(ages:≤40 years)was measured by a dual photon absorptiometry(DPA)and the fracture risk was determined. The patients were separated into two groups according to the following two criteria, respectively:(A)the types of SCI was separated as quadriplegics and paraplegics, and(B)the periods after SCI attack was recorded as short(SCI≤1 year)or long(SCI＞1 years). Results: The results showed 39 cases(78%)had fracture risks in RFN. We compared the incidences of fracture risks between quadriplegics and paraplegics SCI and between short and long periods after SCI attack. The higher incidence of fracture risks in quadriplegia SCI patients was found(93%),but no significant differences for the incidence of fracture risks existed between the patients with shorter and longer periods after SCI. Conclusions: We conclude that femoral neck fractures should be a common complication of SCI. The incidence with fracture risks of femoral necks are influenced by types of SCI lesions, not by SCI periods.

Printed Paper Robot Driven by Electrostatic Actuator (2017)

Effective design and fabrication of 3-D electronic circuits are among the most pressing issues for future engineering. Although a variety of flexible devices have been developed, most of them are still designed two-dimensionally. In this letter, we introduce a novel idea to fabricate a 3-D wiring board. We produced the 3-D wiring board from one desktop inkjet printer by printing conductive pattern and a 2-D pattern to induce self-folding. We printed silver ink onto a paper to realize the conductive trace. Meanwhile, a 3-D structure was constructed with self-folding induced by water-based ink printed from the same printer. The paper with the silver ink self-folds along the printed line. The printed silver ink is sufficiently thin to be flexible. Even if the silver ink is already printed, the paper can self-fold or self-bend to consist the 3-D wiring board. A paper scratch driven robot was developed using this method. The robot traveled 56 mm in 15 s according to the vibration induced by the electrostatic force of the printed electrode. The size of the robot is 30 × 15 × 10 mm. This work proposes a new method to design 3-D wiring board, and shows extended possibilities for printed paper mechatronics.
Genetic association of mating types and virulence in Cryptococcus neoformans (1992)

A pair of congenic Cryptococcus neoformans var. neoformans strains, B-4476 (a mating type) and B-4500 (alpha mating type), that presumably differ only in mating type was constructed. This pair and their progeny, five alpha type and five a type, were tested for virulence in mice. In the parent strains as well as the progeny, alpha type was clearly more virulent than a type. In addition, death tended to occur earlier among the alpha-strain-infected mice that died than among the mice that died by infection caused by a strains. These data strongly suggest the genetic association of virulence with mating type in this human fungal pathogen.

Wafer-scale broadband antireflective silicon fabricated by metal-assisted chemical etching using spin-coating Ag ink (2011)

We report broadband antireflective disordered subwavelength structures (d-SWSs), which were fabricated on 4-inch silicon wafers by spin-coating Ag ink and metal-assisted chemical etching. The antireflection properties of the d-SWSs depend on its dimensions and heights, which were changed by the sintering temperature of the spin-coated Ag ink and etching time. The fabricated d-SWSs drastically reduced surface reflection over a wide range of wavelengths and incident angles, providing good surface uniformity. The d-SWSs with the most appropriate geometry for practical solar cell applications exhibit only 1.23% solar-weighted reflectance in the wavelength range of 300-1100 nm and average reflectance <5% up to an incident angle of 55° in the wavelength range of 300-2500 nm. This simple and low-cost nanofabrication method for antireflection could be of great importance in optical device applications because it allows mass production without any lithography processes or sophisticated equipment.
High frequency of<i>OTOF</i>mutations in Chinese infants with congenital auditory neuropathy spectrum disorder (2016)

Auditory neuropathy spectrum disorder (ANSD) is one of the most common diseases leading to hearing and speech communication barriers in infants and young children. The OTOF gene is the first gene identified for autosomal recessive non-syndromic ANSD, and patients with OTOF mutations have shown marked improvement of auditory functions from the cochlear implantation, but the true involvement of OTOF mutations in Chinese ANSD patients is still unknown which precludes the effective management of this disease. Here, we investigated the contribution of OTOF mutations to congenital ANSD patients in China. In all, 37 infants and young Children with ANSD were screened for all the exons of OTOF gene, of them 34 patients had no neonatal risk factors who were considered as congenital ANSD. The clinical manifestation and audiometric features were also investigated and compared in patients with and without OTOF mutations. In all, 14 of these subjects were shown to carry two or three mutant alleles of OTOF with the high frequency of 41.2% in congenital ANSD patients. In total, 15 novel pathogenic mutations and 10 reported mutations were identified. Our results confirmed that mutations in OTOF gene were a major cause of congenital ANSD in China. Identification of OTOF mutations can facilitate diagnosis, clinical intervention and counseling for congenital ANSD.
LRIG and cancer prognosis (2014)

LRIG gene statuses and mRNA and protein expression are clinically relevant prognostic indicators in several types of human cancer. We propose that LRIG analyses could become important when making informed and individualized clinical decisions regarding the management of cancer patients.
Evaluation of a series of tyrosine‐derived polycarbonates as degradable biomaterials (1994)

A series of four polycarbonates derived from the ethyl, butyl, hexyl, and octyl esters of desaminotyrosyl-tyrosine was prepared by condensation polymerization. The resulting polymers had weight average molecular weights ranging from 120,000-450,000, and their chemical structure was confirmed by elemental analysis, nuclear magnetic resonance, and Fourier transform infrared spectroscopy. The polycarbonates were evaluated as degradable biomaterials. Their surface properties were determined by electron spectroscopy for chemical analysis, attenuated total reflectance-Fourier transformed infrared spectroscopy, and contact angle measurement. The degree of surface hydrophobicity was related to the length of the alkyl ester pendent chain. The tensile properties were dependent on the chemical structure of the polymers: For thin, solvent cast film specimens, the tensile modulus varied from 1.2-1.6 GPa, and the strength at break from 60-220 MPa. The degradation of polymeric films was followed in vitro by measuring changes in mechanical strength for up to 40 weeks, and the decrease in molecular weight and changes in surface chemistry for up to 80 weeks. The length of the pendent chain affected the degradation behavior and strength retention; the polymers with short pendent chains were more readily hydrolyzable. For sterilization, ethylene oxide treatment was less destructive, as judged by molecular weight retention, than gamma-irradiation. Spin-cast films of all tested polycarbonates were not cytotoxic toward cultured rat lung fibroblasts. The cell response was influenced by the chemical structure of the polymer. The least hydrophobic polycarbonate (having a short ethyl ester pendent chain) was a more stimulating substrate for cell growth than the more hydrophobic polymers (carrying longer alkyl ester pendent chains).
Modern Variants of the Mannich Reaction (1998)

Important building blocks for the synthesis of drugs or natural products are found in Mannich bases and their derivatives. Modern variants of the Mannich reaction that expand the potential of the classical intermolecular reaction significantly and enable efficient control of the regioselectivity and stereoselectivity are therefore the topic of intensive research. Intramolecular reactions, in particular as part of domino reaction sequences, often afford astoundingly simple and elegant approaches to complex target compounds.
Munc13-1 C1 Domain Activation Lowers the Energy Barrier for Synaptic Vesicle Fusion (2007)

Synapses need to encode a wide dynamic range of action potential frequencies. Essential vesicle priming proteins of the Munc13 (mammalian Unc13) family play an important role in adapting vesicle supply to variable demand and thus influence short-term plasticity characteristics and synaptic function. Structure-function analyses of Munc13s have identified a "catalytic" C-terminal domain and several N-terminal modulatory domains, including a diacylglycerol/phorbol ester [4beta-phorbol-12, 13-dibutyrate (PDBu)] binding C1 domain. Although still allowing basal priming, a Munc13-1 C1 domain mutation (H567K) prevents PDBu induced potentiation of evoked transmitter release, leads to strong depression during trains of synaptic activity, and causes perinatal lethality in mice. To understand the mechanism of C1 domain-mediated modulation of Munc13 function, we examined how PDBu increases neurotransmitter release. Analyses of osmotically induced release as well as Ca2+ triggered and spontaneous release showed that PDBu increases the vesicular release rate without affecting the size of the readily releasable vesicle pool, linking C1 domain activation to a lowering of the energy barrier for vesicle fusion. PDBu binding-deficient mutant Munc13-1(H567K) synapses mirrored the vesicular release properties of PDBu-potentiated wild-type synapses, indicating that Munc13-1(H567K) is a gain-of-function mutant, which conformationally mimics the PDBu-activated state of Munc13-1. We propose a PKC analogous two-state model of regulation of Munc13s, in which the basal state of Munc13s is disinhibited by C1 domain activation into a state of facilitated vesicle release, regardless of whether the release is spontaneous or action potential triggered.
Free Radical Formation in Wool Fibers Treated by Low Temperature Plasma (2003)

Electron spin resonance studies of merino wool fabrics provide evidence of the presence of stable free radicals. Ultraviolet/visible (λ > 250 nm) irradiation increases the radical concentration. Nitrogen, air, and water vapor plasma treatments on wool fabrics result in new signal bands attributed to nitrogen-centered radicals. The formation of the different additional radicals could be related to the high reactivity of the plasma species or to the vacuum-ultraviolet radiation component (λ < 200 nm) of the plasma environ ment. The presence of these radicals depends on the treatment time and the kind of gas used for plasma generation.
A decade of progress with valve-regulated lead/acid batteries (2002)

The construction and operation of two types of valve-regulated lead/acid (VRLA) cells are described, both using absorptive glass mat separators. Various failure modes have been identified over a period of time but it is shown that many of these have been eliminated through design and improved processing. As a result, predicted design lives are being achieved and reliable operation is assured. The importance of battery monitoring is also examined. Cell voltages, current, time and temperature are readily measured and the data stored for subsequent interrogation or for immediate fault indication. These systems can improve overall reliability. Future directions for the development of VRLA batteries are outlined.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis of inorganic fullerene-like WS<sub>2</sub>nanoparticles and their lubricating performance (2006)

A facile, large-scale and low-cost route was used to synthesize inorganic fullerene-like (IF) WS2 nanoparticles by the reaction of sulfur powder (S) and as-prepared WO3 nanoparticles in a hydrogen atmosphere at a heating temperature of 500–650 °C. The as-synthesized IF-WS2 nanoparticles are of a closed hollow cage structure with an average size of about 50 nm. The composition, morphology and structure of the products were characterized by XRD, TEM, FE-SEM, and HRTEM. The influences of the main reaction conditions were investigated and the possible growth mechanism are proposed. It is worth noting that through changing the amount of as-prepared composite powder (WO3 and S) and the content of hydrogen, yields of IF-WS2 in larger scales can accordingly be easily obtained, and such a synthetic route may also be used in the synthesis of other transition IF metal dichalcogenides. Furthermore, tribological experiments emphasized the important role played by these as-synthesized IF-WS2 nanoparticles in providing excellent lubricating performance, which may bring a much brighter future for their applications in the lubricating field, or even arouse great interest of both scientists and industrialists for their many other important applications.
IUD litigation: the Planned Parenthood experience. (1992)

This review of the IUD litigation experience of Planned Parenthood in the U.S. from 1977-1988 involved 18 injuries allegedly caused by the plaintiff's use of an IUD. These 18 IUD cases represent 9.8% of the total malpractice lawsuits involving Planned Parenthood in the period. 7 were dismissed, 8 were settled, 1 was decided in favor of the defense, and 2 were decided in favor of the plaintiff. While the disposition of these cases is similar to the overall malpractice experience nationally, it is unusual in that twice as many verdicts were for the plaintiff. It is likely that the public perception that IUDs are dangerous made it difficult to select an impartial jury. Pelvic inflammatory disease (PID) was the most common alleged injury, 15 of 18. Even though the scientific evidence predicts otherwise, 15 of the 16 cases of PID occurred over 4 months after insertion. 8 of 15 cases involves Copper-7 IUDs, 4 Dalkon shields, 1 a Progestasert, and 2 Saf-T-Coils. The other 2 cases were 1 uterine perforation and 1 pregnancy. Of the 8 cases that were settles, the mean payment was $20,912, and the median $10,000. These payments are about 25% higher than average non-IUD cases. Payments by insurance companies averaged $21,644 in the late 1970s for IUD claims. In jury cases involving IUDs and Planned Parenthood, the average jury award was $50,000. It is recommended that providers take care especially to comply fully with an IUD manufacturer's protocol, and obtain full and complete informed consent with documentary proof to decrease the possibility of an adverse outcome in potential litigation.
Purification and Properties of <scp>d</scp>(−)‐3‐Hydroxybutyrate‐Dimer Hydrolase from <i>Zoogloea ramigera</i> I‐16‐M (1981)

D(−)‐3‐Hydroxybutyrate‐dimer hydrolase from Zoogloea ramigera I‐16‐M was purified 7000‐fold to electrophoretic homogeneity. The molecular weight of the purified enzyme was 28000 as determined by Sephadex G‐100 gel filtration, and 30000 as estimated by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The isoelectric point was at pH 5.7. The pH optimum for the enzyme reaction was 8.0. The dimer hydrolase was stereospecific for d (−)‐3‐[ l (−)‐3‐hydroxybutyryloxy] butyric acid ( dl ‐dimer) but also hydrolyzed d (−)‐3‐[ d (+)‐3‐hydroxybutyryloxy] butyric acid ( dl ‐dimer) and d (+)‐3‐[ d (−)‐3‐hydroxybutyryloxy]butyric acid ( ld ‐dimer) at reduced rates. However, the enzyme did not attack l (+)‐3‐[ l (+)‐3‐hydroxybutyryloxy]butyric acid ( ll ‐dimer) at all. In addition, the purified hydrolase hydrolyzed several oligomeric esters of d (−)‐3‐hydroxybutyric acid ( ddd ‐trimer, dddd ‐tetramer and ddddd ‐pentamer) faster than dd ‐dimes. Time course experiments with these oligomers and analysis of hydrolytic products of dddd ‐tetramer methyl ester with the hydrolase indicated that the enzyme attacked these substrates from the free hydroxyl terminus, releasing monomer units one at a time.
TMTpro: Design, Synthesis, and Initial Evaluation of a Proline-Based Isobaric 16-Plex Tandem Mass Tag Reagent Set (2019)

The design and synthesis of a proline-based reporter isobaric Tandem Mass Tag structure (TMTpro) is presented. An analysis is made of the performance of the new TMTpro tags in comparison with the current commercially available dimethylpiperidine-reporter-based TMT10/11 reagents. The new reporter structure provides a set of 16 tags for use with resolution of 6.3 mDa mass differences in high resolution mass spectrometers and a set of 9 reagents with 1 Da spacing between reporter ions for single dalton analysis using 9 heavy nuclei per tag. We show similar performance in terms of peptide identification rates and quantification between the TMTpro 16-plex and TMT10/11-plex reagents. We also demonstrate the suitability of the TMTpro reagents for phosphopeptide analysis. The ability to pool 16 samples reduces the overall amount of sample required for each channel, and we anticipate that TMTpro reagents will be a useful enhancement for any protocol that benefits from sample pooling and should reduce missing data.
An experiment study on wound healing with exogenous hyaluronic acid (2000)

Objective To evaluate the effects and possible mechanisms of hyaluronic acid (HA) to inhibit scar formation as well as the dose dependent relationship.Methods Forty five health adult SD rats in a dorsal trauma model were randomly divided into the 2% HA treated group( group A),1% HA treated group(group B),and the PBS treated group as a control group(group C).The process of healing was observed,the remained wound areas were measured,and a mean wound healing time was calculated.Furthermore, the dynamic analysis was performed on local tissue protein,HPr and PCⅢ contents.Results ①The remained wound areas of the control group were much smaller than that of group A and B ,and the mean value of wound healing time was 15 2±2 0,14 2±1 6 and 13 4±1 4 days respectively.②Histologically,when compared qualitatively with PBS controls,HA treated wounds exhibited a less inflammatory response and angiogenesis. The fibroblast proliferated significantly,and the collagen fibril was slender and arrayed in good order,③The contents of tissue HPr were statistically lower in HA treated groups,while the contents of PCⅢ were statistically higher compared to the control group.Conclusions The study indicated that ①The exogenous hyaluronan acid may effectively inhibit collagen synthesis and increase tissue PCⅢ content.As a result,the scar formation was decreased.②Hyaluronal efficacy presented a dose dependent manner.\;
Use and Quality of Care at a VA Outreach Clinic in Northern Maine (2012)

A part-time outreach clinic improved the convenience of primary care for rural VA outpatients, though quality of care was reduced for some measures related to equipment and staffing limitations. Most patients at any VA site had a local, non-VA medical doctor with whom they remained in care while using VA services.
