Laboratory and clinical reliability of conformally coated subretinal implants (2017)

Despite recent developments and new treatments in ophthalmology there is nothing available to cure retinal degenerations like Retinitis Pigmentosa (RP) yet. One of the most advanced approaches to treat people that have gone blind due to RP is to replace the function of the degenerated photoreceptors by a microelectronic neuroprosthetic device. Basically, this subretinal active implant transforms the incoming light into electric pulses to stimulate the remaining cells of the retina. The functional time of such devices is a crucial aspect. In this paper the laboratory and clinical reliability of the two active subretinal implants Alpha IMS and Alpha AMS is presented. Based on clinical data the median operating life of the Alpha AMS is estimated to be 3.3 years with a one-sided lower 75 % confidence level of 2.0 years. This data shows a significant improvement of the device lifetime compared to the previous device Alpha IMS which shows a median lifetime of 0.6 years with a lower confidence bound (75 %) of 0.5 years. The results are in good agreement with laboratory data from accelerated aging tests of the implant components, showing an estimated median lifetime for Alpha IMS components of 0.7 years compared to the improved lifetime of Alpha AMS of 4.7 years.
Dynamic test emulation for EDA-based mixed-signal test development automation (2002)

This paper presents the analysis and development of an Electronic Design Automation (EDA)-based Test Development Automation (TDA) system. We explore the need for such a system and provide a real example of the system at work. The focus of the paper is the concept of dynamic test emulation which understands that a mixed-signal test often consists of obtaining information from a large number of measurements taken at different times through the use of complex digital and analog test patterns. Our work concentrates on bringing together two existing communities, EDA and test development, by linking their separate environments and providing a platform for test and device development that does not require the existence of a physical integrated circuit and a physical Automatic Test Equipment (ATE) system.
High contrast computed tomography with synchrotron radiation (1995)

This article describes a new monochromatic x-ray CT system using synchrotron radiation with applications in biomedical diagnosis which is currently under development. The system is designed to provide clear images and to detect contrast materials at low concentration for the quantitative functional evaluation of organs in correspondence with their anatomical structures. In this system, with x-ray energy changing from 30 to 52 keV, images can be obtained to detect various contrast materials (iodine, barium, and gadolinium), and K-edge energy subtraction is applied. Herein, the features of the new system designed to enhance the advantages of SR are reported. With the introduction of a double-crystal monochromator, the high-order x-ray contamination is eliminated. The newly designed CCD detector with a wide dynamic range of 60 000:1 has a spatial resolution of 200 μm. The resulting image quality, which is expected to show improved contrast and spatial resolution, is currently under investigation.
Diagnosis and Management of Suspected Cases of Bioterrorism: A Pediatric Perspective (2002)

Since October 3, 2001, the Centers for Disease Control and Prevention and other organizations have been investigating potential bioterrorist-related anthrax cases. The pediatrician may be faced with complex issues related to diagnosis and treatment of illnesses caused by intentionally released biological agents. The agents that pose a major potential bioterrorist threat are reviewed by the clinical syndromes they produce: acute respiratory distress with fever, influenza-like illnesses, acute rash with fever, neurologic syndromes, and blistering syndromes. Specific and detailed diagnostic, treatment, and prophylaxis information is provided for anthrax, plague, tularemia, smallpox, botulism, viral hemorrhagic fevers, and other diseases. In cases of suspected bioterrorism, the pediatrician must be able to obtain diagnostic and treatment information efficiently and expeditiously. The system controlling the interaction between public and nonpublic health laboratories in suspected cases of bioterrorism is described. Finally, information regarding emergency contacts and links to educational resources is provided.
3D culture of mouse iPSCs in hydrogel core-shell microfibers (2015)

This paper reports the culturing and expansion of mouse induced pluripotent stem cells (iPSCs) in hydrogel core-shell microfibers; the core consists of iPSCs with or without extracellular matrix (ECM) proteins, and the shell is composed of calcium alginate. We revealed that mouse iPSCs cultured in the micro-scale space with ECM proteins sustain their pluriotency efficiently. This 3D culture system may be a useful tool to expand iPSCs for clinical use.
Accurate measurement of out-of-plane particle displacement from the cross correlation of sequential digital in-line holograms (2013)

A new method to quantify three-dimensional particle fields using digital in-line holography is presented. From sequentially recorded holograms, the maximum cross correlation of edge sharpness within local particle windows yields an accurate measurement of particle displacements. Experiments demonstrate out-of-plane displacement uncertainty of approximately 0.15 mean particle diameters, which is roughly an order-of-magnitude improvement compared with alternative methods. Application to shotgun pellets demonstrates robustness despite experimental noise.

Preformed PAF‐acether and lyso PAF‐acether are bound to blood lipoproteins (1988)

PAF-acether (PAF) is a newly formed mediator not normally present in circulating blood. A compound exhibiting all of its biological characteristics but coeluting with phosphatidylcholine (PC) in high-pressure liquid chromatography (HPLC) was unveiled ('peak X') in normal human plasma. A second HPLC run of peak X HPLC fractions revealed the presence of PAF itself with concomitant disappearance of peak X. Beside PAF, immunoreactive apolipoproteins A-I and E were found in peak X. Also lipoproteins (Ls) purified using either ultracentrifugation or immunoaffinity chromatography yielded peak X and, in a second HPLC run, authentic PAF. L-free plasma was devoid of peak X. Finally, after preincubation with plasma, labeled PAF was found associated with Ls. Thus in human blood preformed PAF is bound in high amounts to Ls, a result of interest given the role of Ls and platelets in vascular diseases and the present knowledge on PAF biosynthesis.
Complications of ventriculoatrial and ventriculoperitoneal shunts in a new children's hospital. (1980)

At a new children's hospital between 1974 and 1978, 125 patients underwent 243 shunt procedures performed by six neurosurgeons. In spite of diverse techniques used, the overall results were acceptable. Seventy-seven patients required 118 shunt revisions. The mortality related to the shunt procedures of 7.2% and the infection rate of 14.4% were comparable to those of other series reported during the same period. Ventriculoatrial shunts, although fewer in number, required fewer revisions (20 revisions of 18 shunts) than ventriculoperitoneal shunts (97 revisions of 58 shunts) for which the variation in technique was larger. A sharp decline in the complication rate was noted during the last year of the study.
Modulation of mRNA levels for urinary- and tissue-type plasminogen activator and plasminogen activator inhibitors 1 and 2 in human fibroblasts by interleukin 1. (1989)

Plasminogen activators and their inhibitors are thought to play an important role in the regulation of a variety of pathologic processes including inflammation and wound healing. IL-1 is one inflammatory mediator which has been shown to increase release of plasminogen activator (PA) Ag and activity by mesenchymal cells such as chondrocytes and synoviocytes. We have found that rIL-1 beta induces a rapid and significant accumulation of both tissue-and urinary-type plasminogen activator (t-PA and u-PA) mRNA and type 1 and 2 plasminogen activator inhibitor (PAI-1 and PAI-2) mRNA in MRC-5 fetal lung fibroblasts. An SV40 transformed fibroblast cell line, XP12RO, showed an identical response of PAI-1 and t-PA message levels but revealed no change in PAI-2 or u-PA mRNA levels with rIL-1 beta stimulation. Treatment with the transcriptional inhibitor actinomycin D blocked accumulation of t-PA, u-PA, PAI-1, and PAI-2 mRNA, suggesting that RNA synthesis is required for accumulation of all four transcripts. Cycloheximide (CHX) treatment altered the rate of PAI-1 and t-PA mRNA accumulation, but both were able to increase in the absence of protein synthesis. CHX blocked the rIL-1 beta-induced increase in PAI-2 mRNA levels normally observed at 8 h, indicating that protein synthesis is required for this response to IL-1. The increase in u-PA message level was augmented in a synergistic fashion by CHX. These data for PAI-2 and u-PA provide evidence for short-lived proteins which act either to modulate transcription of these genes or regulate mRNA stability. Thus plasminogen activators and their inhibitors are regulated in a positive and complex fashion in the fibroblast by IL-1, suggesting an important role for these molecules and this cell type in the response to inflammation.
Impulse based scheme for crystal-less ULP radios (2008)

This work describes a method of implementing a fully-integrated ultra-low power (ULP) radio for wireless sensor networks (WSN). This is achieved using a specific medium access control (MAC) protocol, employing a duty- cycled wake-up radio and a crystal-less clock generator, and an ad-hoc modulation scheme (Impulse Radio) with a bandwidth of 17.7 MHz in the 2.4 GHz - ISM band. The total average power consumption is expected to be less than 100 muW.
Neurophysiology of the parieto-frontal system during target interception. (2004)

We studied the functional properties of neurons of two elements of the parieto-frontal system: area 7a of the PPC and the motor cortex (M1), during an interception task of stimuli moving in real (RM) and apparent motion (AM). The stimulus moved along a circular path with one of 5 speeds, and was intercepted at 6 o'clock by exerting a force pulse on a joystick. A smooth stimulus motion was produced in RM, whereas in AM 5 stimuli were flashed successively at the vertices of a pentagon. The results showed, that a group of neurons in both areas above responded not only during the interception but also during a NOGO task in which the same stimuli were presented in the absence of a motor response. Most of these neurons were tuned to the stimulus angular position. In addition, we found that the time-varying neuronal activity in both areas was related to various aspects of stimulus motion and hand force, with stimulus-related activity prevailing in area 7a and hand-related activity prevailing in M1. Interestingly, the neural activity was selectively associated with the stimulus angle during RM, whereas it was tightly correlated to the time-to-contact during AM. Thus, the results suggest that area 7a was processing high level features of the circularly moving stimuli and was involved in the production of an early command signal for stimulus interception, whereas M1 was still processing some aspect of the visual stimulus that were used to trigger the interception movement using a predictive mechanism.
Roles of catalytic residues in α-amylases as evidenced by the structures of the product-complexed mutants of a maltotetraose-forming amylase (1999)

The crystal structures of the four product-complexed single mutants of the catalytic residues of Pseudomonas stutzeri maltotetraose-forming alpha-amylase, E219G, D193N, D193G and D294N, have been determined. Possible roles of the catalytic residues Glu219, Asp193 and Asp294 have been discussed by comparing the structures among the previously determined complexed mutant E219Q and the present mutant enzymes. The results suggested that Asp193 predominantly works as the base catalyst (nucleophile), whose side chain atom lies in close proximity to the C1-atom of Glc4, being involved in the intermediate formation in the hydrolysis reaction. While Asp294 works for tightly binding the substrate to give a twisted and a deformed conformation of the glucose ring at position -1 (Glc4). The hydrogen bond between the side chain atom of Glu219 and the O1-atom of Glc4, that implies the possibility of interaction via hydrogen, consistently present throughout these analyses, supports the generally accepted role of this residue as the acid catalyst (proton donor).
Radioactive derivatives of 2-methyl-1, 4-naphthoquinol bis (diphosphate salt) as anti-cancer drugs with high LET radiations. (1984)

From the results of the alpha-particle track autoradiography, the alkaline phosphatase studies, the biodistribution investigations and the therapeutic experiments with the transplanted Franks and Hemmings (1978) adenocarcinoma of the rectum in mice, an important finding is the striking selectivity of the uptake of the compound 6-211 At-astato-2-methyl-1, 4-naphthoquinol bis (diphosphate salt), after intraperitoneal injection into the tumour cell nuclei and in many cases into the nuclei of tumour stem cells, together with negligible uptake into normal colon and narrow. The compound, 6-211 At-astato-2-methyl-1, 4-naphthoquinol bis (diphosphate salt) has been found to cure about two-thirds of the transplanted adenocarcinoma of the rectum in mice after a single intra-peritoneal injection of 3-4 microCi. This approach can be regarded as a form of metabolically-directed drug targetting on to a tumour product which is an enzyme, an alkaline phosphatase isozyme, present in the cells of some tumours. The compound is being studied further from the point of view of possible human therapeutic applications.
A Digital Integrator for On-Line Signal Processing (1963)

A concept for approximate digital integration is presented. The integrator is equivalent to the RC-integrator (but has no drift) and has an arbitrary long time constant. An example is given showing application to polarity coincidence correlation detection of signals in noise.
The presence of acetyl groups in histones (1963)

the sensitivity of the detection apparatus. As only part of the soil nitrogen is present in living microorganisms, it appears that the conversion of 2,6- dichlorobenzaldoximes is brought about by micro- organisms and not, or very slowly, by higher plants. SUMMARY 1. Soil micro-organisms convert a range of 2,'6-dichlorobenzaldoximes into 2,6-dichlorobenzo- nitrile.
Relaxation effects in magnetic recording (1996)

Master equation formalism is employed to describe the effect of a recording head on an initially demagnetized particulate medium. It is found that transition noise and transition shift along the track are inversely correlated and that large transition noise is found to be associated with high recording frequencies, low recording temperatures (large particles) and particle misalignment. Interparticle coupling is discussed.
Cloning and Expression in <i>Escherichia coli</i> of a Synthetic DNA for Hirudin, the Blood Coagulation Inhibitor in the Leech (1986)

A 235-bp DNA coding for the leech blood coagulation inhibitor, hirudin, was chemically synthesized. The synthesis involved preparation of seven long oligodeoxyribonucleotide pairs which were assembled and cloned using a rapid and simple procedure. More than half of the transformed Escherichia coli cells expressed a biosynthetic polypeptide having biological properties which were very similar to authentic hirudin from the leech Hirudo medicinalis. To achieve efficient expression, we fused the hirudin DNA to a truncated C1 repressor gene of bacteriophage lambda to create a hybrid protein. An additional methionine at the fusion point allowed the active hirudin to be cleaved off by cyanogen bromide.
The wire grid microstrip antenna (1981)

A description is given of an antenna consisting of an interconnected wire grid formed by etching metallic lines on a dielectric sheet backed by a metallic ground plane. The theory of operation, analytical model, and experimental findings for this approach to a printed array are described. The device is low cost, light weight, and has sufficient bandwidth to be of use in a variety of applications. An analytical model is developed which establishes transmission line equivalent circuits for the wire grid elements. Current distributions determined from the model are shown to predict accurately the measured pattern performance of a typical implementation. The bandwidth as established by various pattern parameters is quantitatively assessed. Particular emphasis is given to methods of amplitude control through control of line impedances. A particular design implementation is presented for a five-wavelength circular array with independent quadrant control. Measured results from this configuration are compared to theory.
Comparing Rewinding and Fine-tuning in Neural Network Pruning (2020)

Many neural network pruning algorithms proceed in three steps: train the network to completion, remove unwanted structure to compress the network, and retrain the remaining structure to recover lost accuracy. The standard retraining technique, fine-tuning, trains the unpruned weights from their final trained values using a small fixed learning rate. In this paper, we compare fine-tuning to alternative retraining techniques. Weight rewinding (as proposed by Frankle et al., (2019)), rewinds unpruned weights to their values from earlier in training and retrains them from there using the original training schedule. Learning rate rewinding (which we propose) trains the unpruned weights from their final values using the same learning rate schedule as weight rewinding. Both rewinding techniques outperform fine-tuning, forming the basis of a network-agnostic pruning algorithm that matches the accuracy and compression ratios of several more network-specific state-of-the-art techniques.
Formation of Isoparaffins through Pd/β Zeolite Application in Fischer−Tropsch Synthesis (2005)

The direct synthesis of isoparaffins from synthesis gas (H2/CO = 2) was carried out in a consecutive dual reactor system under the conditions of P = 1.0 MPa and W/F = 4.97 g·h·mol-1. In the upper reactor, Co/SiO2 was used for Fischer−Tropsch (FT) reaction. To primarily decompose the heavy FT hydrocarbons, zeolite β (4:1 weight ratio) was physically mixed with Co/SiO2. The Pd/β catalyst with a Pd loading of 0.5 wt % and different Si/Al ratios in zeolites β was loaded in the lower reactor for hydroconverting the products from the upper reactor. Irrespective of the Si/Al ratio of zeolite β, the results indicate that the final products showed a sharp carbon number distribution in the range of C4−C6 and very high selectivity to branched isomers of C4−C6 alkanes. An apparent change of selectivity to isoparaffins was observed with the variation of the Si/Al ratio in Pd/β catalyst. Moreover, the stability of the catalyst was also influenced by the Si/Al ratios. The effect of the Si/Al ratio on the selectivity of isomers at different times on stream was correlated with the acidity and crystallization of the β zeolite, which were characterized by ammonia TPD and XRD methods.

Fast frequency calibration of VCO's in phase-locked loops (2010)

This paper presents a novel technique to achieve fast calibration of the voltage-controlled oscillator (VCO) into the optimum subband of operation.The pro posed technique is pre-dominantly digital thus exhibiting low power/area requirements, in addition to greatly reduced calibration times, suitable for application in lower tech nology nodes.To verify the proposed technique the VCO and corresponding calibration circuitry is modelled as part of a charge-pump phase locked loop (CP-PLL) in UMC's 90nm process.VCO operation is split into 16 different subbands (i.e.4-bit calibration) with each subband exhibiting a gain (Kvco) of � 50MHz/V to achieve an overall tuning range of � 10%.Through application of the proposed technique, calibration into the optimum subband of VCO operation is shown to occur in minimal time.
