Double wavelength selective GaAs/AlGaAs infrared detector device (1992)

We demonstrate the first GaAs/AlGaAs multiquantum well infrared detector device with double wavelength selectivity and high wavelength resolution. By applying an efficient light coupling mechanism, which is based upon the excitation and emission of surface plasmons, we have achieved a responsivity R of 2.20 A/W and a detectivity D* of 2.2×1011 cm √Hz/W for λ=7.38 μm at a temperature T=5 K for a 300 K background irradiance and a 90° field of view, which are one of the highest values reported to date.
MCube: A high performance and fault-tolerant network architecture for data centers (2010)

A fundamental challenge in data center networking is how to efficiently interconnect a huge amount of servers. The network architecture typically consists of a tree of routing and switching elements with progressively more specialized and expensive equipment moving up the network hierarchy. Unfortunately, even when deploying the highest-end IP switches/routers, resulting topologies remain complicate application design and limit overall system performance. This paper presents MCube, a server-centric network architecture specifically designed for data centers. MCube leverages commodity mini-switches to provide high aggregate bandwidth and can deliver more performance at less cost than available from today's higher-end solutions. MCube is fully backward compatible with Ethernet, IP, and TCP and provides higher network capacity than the traditional tree-based structure for various types of services. Furthermore, MCube is also fault tolerant since it does not have single point of failure and its source routing protocol performs near shortest-path routing even in the presence of severe link or node failures. Experiences show that MCube is fault tolerant and load balancing and it significantly accelerates the bandwidth-intensive applications.
Airflow Perturbation Device for Measuring Airways Resistance of Humans and Animals (1984)

This communication introduces the airflow perturbation device (APD) as a means for measuring airways resistance in humans and animals The APD uses a rotating screen to perturb airflow during spontaneous breathing. The resultant mouth pressure perturbation amplitudes are divided by flow rate perturbation amplitudes to give airways resistance. Data shown for both humans and swine demonstrate values to be in the correct magnitude range, and to reflect changes in flow rate and direction.
Dosimetric and QA aspects of Konrad inverse planning system for commissioning intensity-modulated radiation therapy (2007)

The intensity-modulated radiation therapy (IMRT) planning is performed using the Konrad inverse treatment planning system and the delivery of the treatment by using Siemens Oncor Impression Plus linear accelerator (step and shoot), which has been commissioned recently. The basic beam data required for commissioning the system were generate. The quality assurance of relative and absolute dose distribution was carried out before clinical implementation. The salient features of Konrad planning system, like dependence of grid size on dose volume histogram (DVH), number of intensity levels and step size in sequencer, are studied quantitatively and qualitatively.To verify whether the planned dose [from treatment planning system (TPS)] and delivered dose are the same, the absolute dose at a point is determined using CC01 ion chamber and the axial plane dose distribution is carried out using Kodak EDR2 in conjunction with OmniPro IMRT Phantom and OmniPro IMRT software from Scanditronix Wellhofer. To obtain the optimum combination in leaf sequencer module, parameters like number of intensity levels, step size are analyzed. The difference between pixel values of optimum fluence profile and the fluence profile obtained for various combinations of number of intensity levels and step size is compared and plotted. The calculations of the volume of any RT structure in the dose volume histogram are compared using grid sizes 3 mm and 4 mm. The measured and planned dose at a point showed good agreement (<3%) except for a few cases wherein the chamber was placed in a relatively high dose gradient region. The axial plane dose distribution using film dosimetry shows excellent agreement (correlation coefficient >0.97) in all the cases. In the leaf sequencer module, the combination of number of intensity level 7 with step size of 3 is the optimal solution for obtaining deliverable segments. The RT structure volume calculation is found to be more accurate with grid size of 3 mm for clinical use.Thus a study regarding various aspects of commissioning of the Konrad inverse planning system for IMRT has been presented, which has been implemented in our clinic.
Association between colony forming units-granulocyte macrophage expression of Ia-like (HLA-DR) antigen and control of granulocyte and macrophage production. A new role for prostaglandin E. (1982)

The expression of Ia-like antigens on human colony forming units-granulocyte macrophage (CFU-GM) is related to S-phase of the cell cycle, and associated with the control of normal granulocyte and macrophage production by prostaglandin E and acidic isoferritins in vitro. Ia-antigen expression by CFU-GM is lost within 3-6 h of culture at 37 degrees C and occurs simultaneously with loss of responsiveness to inhibition by these factors. Culture of bone marrow CFU-GM in a limited exposure suspension culture with 1 microM-1pM prostaglandin E (PGE1 or PGE2), but not prostaglandin F2 alpha or dibutyryl-cyclic-3'-5'-AMP results in the detection of CFU-GM Ia-antigen after 24 h. Antigen expression is associated with an absolute increase in total and S-phase CFU-GM, and restoration of responsiveness to inhibition by prostaglandin E and acidic isoferritins. The detection of Ia-antigen on CFU-GM after suspension culture with prostaglandin E results both from Ia-antigen reexpression as well as stimulation of noncycling cells to enter S-phase, express Ia-antigen and give rise to CFU-GM sensitive to inhibition by prostaglandin E and acidic isoferritins. The sensitivity of CFU-GM to inhibition by these factors after suspension culture with prostaglandin E is identical to that of the same cells tested prior to the suspension culture. These studies provide evidence for a direct regulatory association between Ia-antigen expression and control of myeloid progenitor cell differentiation, and suggest a role for prostaglandin E in the control of CFU-GM cell cycle, Ia-antigen expression, and growth regulation.
Scanning probe microscopy: Current status and future trends (1990)

The scanning tunneling microscope has shown us that it is possible to control and scan a tip over a conducting surface with angstrom precision. More recently, the same generic principle of the scanning tunneling microscope (STM) has been applied to many other novel scanned probe microscopies. In general all these microscopies come under the class of microscopy called superresolution microscopy—i.e., the spatial resolution achievable is far better than that dictated by the wavelength used to form, the image. Following a review of the history behind the development of scanned probe microscopes, is presented work on the recent developments in the areas of atomic force microscopy, magnetic force microscopy, electrostatic force microscopy, near-field thermal microscopy, and near-field acoustic microscopy. These will be highlighted by results from each area which illustrate the potential of these techniques to provide new information about the physical properties of surfaces on a nanometer scale.
Molecular Engineering of a PheS Counterselection Marker for Improved Operating Efficiency in <i>Escherichia Coli</i> (2015)

Escherichia coli phenylalanyl-tRNA synthetase, a-subunit (ePheS) can be useful as a counterselection marker since its A294G variant misincorporates 4-chloro-phenylalanine (4CP) into cellular proteins during translation, thereby causing cell death. The drawback of this method is that selection must be performed in minimal or semisynthetic medium to avoid interference from phenylalanine in the medium. Here, I reengineered ePheS for improved 4CP incorporation efficiency, obtaining variants (T251A/ A294G and T251S/A294G) that exhibited high lethality in Luria-Bertani medium (LB) containing 4CP. These new variants were superior to the A294G variant when used as a counterselection marker in vector curing experiments.
A double-blind, randomised trial of tesaglitazar versus pioglitazone in patients with type 2 diabetes mellitus (2007)

The efficacy and safety of tesaglitazar (0.5 and 1 mg) and pioglitazone (15, 30 and 45 mg) were compared in a 24-week, randomised, double-blind study in 1,707 patients with type 2 diabetes mellitus. Tesaglitazar 1 mg was non-inferior to pioglitazone 45 mg for change from baseline in glycosylated haemoglobin (HbA1C) at 24 weeks (difference: -0.056 [95% confidence intervals -0.161, 0.049], pNI<0.001 for non-inferiority hypothesis). Tesaglitazar 1 mg improved triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and non-HDL-C levels compared with all pioglitazone doses at 24 weeks (p<0.001). Low-density lipoprotein cholesterol (LDL-C) was lower with tesaglitazar for all pioglitazone comparisons (p<0.05), except for tesaglitazar 0.5 mg versus pioglitazone 15 mg. Tesaglitazar 1 mg decreased LDL particle number, when compared with all pioglitazone doses (p<0.01). Both agents increased body weight and peripheral oedema in a dose-dependent manner, but only tesaglitazar increased serum creatinine. In summary, tesaglitazar provided similar glycaemic control to pioglitazone, was associated with significant improvement in lipid and lipoprotein variables, and increased serum creatinine in a dose-dependent manner.
Obstructive sleep apnea and associated attrition, active component, U.S. Armed Forces, January 2004-May 2016. (2016)

Obstructive sleep apnea (OSA) is a growing health concern in both civilian and military populations. Individuals who suffer from OSA have increased rates of cardiovascular disease, chronic fatigue, motor vehicle accidents, cognitive impairment, and post-traumatic stress disorder. Data from the Defense Medical Surveillance System (DMSS) were utilized to examine the incidence of OSA and associated attrition from service in active component military members from 1 January 2004 through 31 May 2016. The study identified 223,731 incident cases of OSA with an overall incidence rate of 139.2 per 10,000 person-years, between 2004 and 2015. Rates increased more than 3-fold between 2004 and 2015. In 2015, 48.1% of all incident cases of OSA were diagnosed in the last year of service. The high percentage of cases diagnosed prior to separation from service is concerning because OSA is a treatable and partially preventable disease. OSA represents a large health and economic burden for the armed services and yet there are persistent research gaps in appropriate screening and prevention strategies to improve both individual health and mission performance.

Reconstruction with free jejunal interposition for defect after tumor resection of hypopharyngeal and cervical esophageal cancer (2009)

Objective To discuss the use of free jejunal flap reconstruction for circumferential defect after tumor resection of hypopharyngeal and cervical esophageal cancer. Methods Retrospective review of 7 pa-tients who underwent hypopharyngeal and cervical esophageal reconstruction with free jejunal interposition from 2005 to 2007. All 7 cases who suffered from hypopharyngeal and cervical esophageal cancer were given resection of the larynx, hypopharynx and cervical esophagus. Neck dissection and postoperative radiotherapy were carried out for all patients. Results All the 7 free jejunal flaps survived completely and the flap success rate was 100%. For successful cases,one case occurred pharyngeal fistula on postoperative thirteenth day and healed on postoperative eighteenth day, One patient was died of the gastrointestinal bleeding on postoperative ninety-five day. one patient couldn' t swallow after five months because of recurrence of pectoral esophageal cancer and died after eleven months. Follow-up 7 to 24 months, five survived cases were no recurrence and dysphagia. Conclu-sion Patients reconstructed with free jejunal flap after resection of hypopharyngeal and cervical esophageal cancer had high successful rate and few complications. The choice of free jejunal flap for reconstruction of hypo-pharyngeal and cervical esophageal defect was appropriate in selected patients.

Synthesis of Cycloolefin−Maleic Anhydride Alternating Copolymers for 193 nm Imaging (1997)

A series of novel cycloolefin−maleic anhydride copolymers have been prepared and evaluated for 193 nm imaging applications. Free radical induced copolymerization of norbornene and maleic anhydride affords a hydrolytically robust alternating copolymer. Aqueous base solubility can be induced via incorporation of acrylic acid and/or acrylate esters that can be cleaved to afford the parent acid via acidolysis. The proportion of acrylate in the resulting terpolymers is a linear function of the starting monomer ratio. These terpolymers are thermally stable and hydrolytically robust. Due to their aqueous base solubility and UV transparency, they have potential in high resolution imaging applications. Sub-0.18 μm imaging has been demonstrated upon 193 nm pattern-wise exposure of selected materials.
Bone Morphogenetic Protein-1 Processes the NH2-terminal Propeptide, and a Furin-like Proprotein Convertase Processes the COOH-terminal Propeptide of pro-α1(V) Collagen (1998)

Bone morphogenetic protein-1 (BMP-1) plays key roles in regulating the deposition of vertebrate extracellular matrix; it is the procollagen C-proteinase that processes the major fibrillar collagen types I-III, and it may process prolysyl oxidase to the mature enzyme necessary to the formation of covalent cross-links in collagen and elastic fibers. Type V collagen is a fibrillar collagen of low abundance that is incorporated into and helps regulate the shape and diameter of type I collagen fibrils. Here we show that, in contrast to its action on procollagens I-III, BMP-1 does not cleave the C-propeptide of pro-alpha1(V) homotrimers. Instead, the single BMP-1-specific cleavage site within pro-alpha1(V) chains, lies within the large globular N-propeptide. This cleavage site is immediately upstream of a glutamine, thus redefining the specificity of cleavage for BMP-1-like enzymes. It also produces an NH2 terminus that corresponds to an equivalent NH2 terminus on the processed matrix form of the similar alpha1(XI) chain, thus suggesting physiological significance. Cleavage of the C-propeptide occurs efficiently in recombinant pro-alpha1(V) homotrimers produced in 293-EBNA human embryonic kidney cells, and this cleavage is shown to occur immediately downstream of the sequence RTRR. This is similar to sites cleaved by subtilisin-like proprotein/prohormone convertases and is shown to be specifically cleaved by the recombinant subtilisin-like proprotein/prohormone convertase furin.

End-to-End Adaptive Packet Aggregation for High-Throughput I/O Bus Network Using Ethernet (2014)

Input/output (I/O) bus networks using Ethernets transfer a PCI Express (PCIe) I/O packet between a host and an I/O device by encapsulating it into an Ethernet frame. Because the size of PCIe packets is generally small in such systems, the overhead to individually encapsulate them into Ethernet frames lowers the PCIe throughput provided by Ethernet connections. This decrease in throughput directly degrades the performance of I/O devices, which transmit high-throughput PCIe traffic. Examples of such devices include PCIe solid-state drives and graphics processing units. We propose a method of aggregating multiple PCIe packets into a single Ethernet frame in an end-to-end manner to provide a high-throughput PCIe connection. The aggregation is performed at the bottleneck-link rate of the Ethernet path through which those packets are transferred. The number of aggregated PCIe packets is adaptively determined by aggregating ones that reside in a transmission queue when it is scheduled to transmit packets. This enables low-latency throughput enhancement because the proposed method does not increase the transmission latency of PCIe packets by waiting for more packets to aggregate. In addition, it does not require individual configuration of operation parameters, such as aggregation threshold and time out value, depending on the rate of the PCIe traffic of I/O devices. We implemented our method in a PCIe-to-Ethernet bridge prototype using a field-programmable gate array. As a result, I/O performance improved up to 41%.

A High-Power and Scalable 2-D Phased Array for Terahertz CMOS Integrated Systems (2014)

This work introduces a 2-D phased array architecture that is suitable for high power radiation at mm-Wave and Terahertz frequencies. We address the challenge of signal generation above the cut-off frequency of transistors by presenting a radiation method based on the collective performance of a large number of synchronized sources. As theory shows, both frequency locking/tuning and beam steering can be independently achieved by manipulating the local coupling between the nearest neighbors. This control method results in a dynamical network that is insensitive to array dimensions and is scalable to the point that can achieve a level of output power and spectral purity beyond the reach of conventional sources. To demonstrate the concept, we implement a 4 ×4 version of this phased array at 340 GHz using a 65 nm bulk CMOS process. The paper presents the design and implementation of the oscillators, couplings and the integrated antennas. The measured results at 338 GHz reveal a peak equivalent isotropically radiated power (EIRP) of +17.1 dBm and a phase noise of -93 dBc/Hz at the 1 MHz offset frequency. This chip presents the first fully integrated terahertz phased array on silicon. Furthermore, the output power is higher than any lens-less silicon-based source above 200 GHz and the phase noise is lower than all silicon radiating sources above 100 GHz.

Design and control of a robotic wrist orthosis for joint rehabilitation (2015)

Ageing society in many countries has led to an increasing number of stroke and cerebral palsy patients who require rehabilitation therapy. Affected wrist joints often show an increased spasticity and stiffness, caused by impairments of surrounding muscles and tendons. However, the medical devices for wrist joint assessment and rehabilitation are lacking. This paper proposes a robotic orthosis to assist the patient's wrist to perform rehabilitation exercise in a compliant way. A 1-DOF robotic device with parallel mechanism is designed for the wrist joint by utilising pneumatic artificial muscles (PAMs) that are compliant and lightweight. The mechanical design of the wrist orthosis and the corresponding development of pneumatic control system will be also presented. A model-based pressure close-loop control strategy is implemented for the PAMs in order to track the trajectory in high-performance. Experiments on the orthosis demonstrated that the robot could assist the hand to move along a torque-sensitive trajectory with relatively small errors and the differential forces were also kept stable.
