Simplified Baseband Diversity Combiner (1960)

In conventional FM receivers, the gain of the limiters rises during a fade to maintain constant output. The resulting sharp rise in noise complicates the problem of diversity combining, requiring the combiner to provide a very high degree of suppression of noisy signals. By suitable limiter design, the necessary AM suppression can be obtained without affecting average receiver gain, permitting the use of simple linear addition at baseband for diversity combining. Cross coupling between limiters of a set of receivers maintains constant combined output. Receivers are simply connected in parallel to provide any degree of diversity. No additional circuits or components are used for the combining function, since operation does not depend on measurement of out-of-band noise. For the same reason, the system is not disabled by loss of pilot tones or by multipath distortion products of interference appearing as excess out-of-space noise. The performance of this combiner compares favorably with other presently used combining methods.
Inkjet Printed RGB Quantum Dot-Hybrid LED (2010)

We report DC driven full color inkjet printed quantum-dots light-emitting devices. The inkjet was used to print monochromatic red, green, and blue, as well as integrate red-green-blue light-emitting quantum dots unto a substrate having QVGA display. The performance of the inkjet printed monochrome devices was on the same order as that of spin coated ones. For the full color RGB devices, a video brightness of 100 cd/m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> is achieved at 9.3 V.
Liver Plasma Membrane: the Source of High Molecular Weight Alkaline Phosphatase in Human Serum (1985)

This study presents biochemical, histochemical, morphological and immunological evidence that part of the high molecular weight alkaline phosphatase observed in the serum of patients with liver disease and particularly in cases of intrahepatic cholestasis or focal-, extrahepatic obstruction originates from the liver plasma membrane. The high molecular weight protein alkaline phosphatase complex contains several plasma membrane enzymes and behaves like a plasma membrane fragment after isopycnic density gradient ultracentrifugation in sucrose, cesium chloride and metrizamide. Electron microscopic examination revealed a triple-layered vesicle which retained alkaline phosphatase activity. Incubation of human liver cells with anti-serum against purified high molecular weight multienzyme complex resulted in fixation of antibodies on the plasma membrane as shown by positive plasma membrane fluorescence. These plasma membrane fragments in the serum are not of biliary origin.
Performance evaluation of a distributed architecture for information retrieval (1996)

Information explosion across the Internet and elsewhere offersaccess toanincreasing number of document collections. In order for users to effectively access these collections, information retrieval (IR) systems must provide coordinated, concurrent, and distributed access. In this paper, we describe a fully functional distributed IR system based on the Inquery unified IR system. To refine this prototype, we implement a flexible simulation model that analyzes perwhich a large number of clients and servers communicate. 1 This model allows us to investi@.e systems that vary from our implementation. We measure system response time,
Comparison of tissue effects with sculptured fiberoptic cables and other Nd:YAG laser and argon laser treatments (1991)

The use of a fiber optic cable in contact with tissue results in a complex thermal interaction between the cable and the tissue. The effect of the laser-tissue interaction was investigated using sculptured quartz fiber optic cables, sapphire contact rods, and bare fiber optic cables attached to the Nd:YAG laser. The laser-tissue effects of the Nd:YAG and argon lasers were compared. Examination of treated animals showed there to be a significant difference between immediate and 48-hour thermal effects. The sculptured fibers created significantly less tissue damage than the sapphire contact tips, the 0.6-mm bare fiber, or the argon laser with a 0.3-mm bare fiber either with or without contact. All Nd:YAG laser contact treatments were less damaging than the argon laser treatments.
Arthroscopic humeral avulsion of the glenohumeral ligaments (HAGL) repair (2004)

Humeral avulsion of the glenohumeral ligaments (HAGL lesion) is one of the pathologic lesions that occurs secondary to anterior glenohumeral instability. Although HAGL lesions occur less commonly than Bankart lesions in cases of anterior instability, it is necessary to understand this pathology and to make the necessary repair. An all-arthroscopic technique using suture anchors can be used to repair HAGL lesions, but it is a difficult and demanding technique. To facilitate this type of repair, the surgeon must be: (1) comfortable with both the 30 degrees and 70 degrees arthroscopes, (2) able to establish and use the 5-o'clock portal, (3) able to abduct and externally rotate the arm, and (4) able to ensure secure fixation of the glenohumeral ligaments to bone through adequate knot and loop security.
Framework of manufacturer‐retailer relationship in the manufactured housing construction (2009)

Purpose The purpose of this paper is to analyze the current customer relationship management (CRM) with regard to manufacturers and retailers in the US manufactured housing (MH) industry and to present an MH industry‐specific framework of CRM system. Design/methodology/approach An overall CRM system was investigated through a questionnaire survey and interviews with industry experts. Based on the analysis of current CRM and the specific data collected, a framework of manufacturer‐retailer relationship optimization model (MRROM) for the MH industry was developed and validated trough the MH industry practitioners. Findings MRROM describes the overall framework of an industry‐specific CRM solution for the MH industry and suggests a new paradigm for the MH customization process as a focus area. Research limitations/implications This research only focused on the framework of optimal CRM system at the macro levels and an optimization model in the critically constrained manufacturer‐retailer relationship areas. Practical implications The proposed framework of MRROM can be used for developing the CRM vision and CRM strategies for the MH industry. It can then be the basis of an assessment of the current and required CRM capabilities of the enterprise. Originality/value Supply chain management for the MH industry is a new area of research. The proposed MRROM will contribute to improving the effectiveness and long‐term success of the supply chain in the MH industry. In addition, the proposed MRROM can be applied to other industries in the similar circumstances as well and is expected to facilitate the overall sales process.
Optimizing Satellite Communications With Adaptive and Phased Array Antennas (2004)

A new adaptive antenna array architecture for low-earth-orbiting satellite ground stations is being investigated. These ground stations are intended to have no moving parts and could potentially be operated in populated areas, where terrestrial interference is likely. The architecture includes multiple, moderately directive phased arrays. The phased arrays, each steered in the approximate direction of the satellite, are adaptively combined to enhance the Signal-to-Noise and Interference-Ratio (SNIR) of the desired satellite. The size of each phased array is to be traded-off with the number of phased arrays, to optimize cost, while meeting a bit-error-rate threshold. Also, two phased array architectures are being prototyped: a spacefed lens array and a reflect-array. If two co-channel satellites are in the field of view of the phased arrays, then multi-user detection techniques may enable simultaneous demodulation of the satellite signals, also known as Space Division Multiple Access (SDMA). We report on Phase I of the project, in which fixed directional elements are adaptively combined in a prototype to demodulate the S-band downlink of the EO-1 satellite, which is part of the New Millennium Program at NASA.
Email Volume Optimization at LinkedIn (2016)

Online social networking services distribute various types of messages to their members. Common types of messages include news, connection requests, membership notifications, promotions and event notifications. Such communication, if used judiciously, can provide an enormous value to members thereby keeping them engaged. However sending a message for every instance of news, connection request, or the like can result in an overwhelming number of messages in a member's mailbox. This may result in reduced effectiveness of communication if the messages are not sufficiently relevant to the member's interests. It may also result in a poor brand perception of the networking service. In this paper we discuss our strategy and experience with regard to the problem of email volume optimization at LinkedIn. In particular, we present a cost-benefit analysis of sending emails, the key factors to administer an effective volume optimization, our algorithm for volume optimization, the architecture of the supporting system and experimental results from online A/B tests.

FEA-Based Design and Fabrication of Functionally Graded Materials (2006)

Functionally Graded Materials (FGMs) are composite materials that have continuous material variation along with geometry. This paper introduces a method for FEA-based design and layered manufacturing (LM) of FGMs. An FGM solid model is first created by referring to the libraries of primary materials and composition functions. The model is then discretized into an object model onto which appropriate material properties are mapped. Next, the object model is adaptively meshed and converted into an FE model. FEA using ANSYS is finally performed to estimate stress levels. This FEA-based design cycle is repeated until a satisfactory solution is obtained. The object model is then fed to the fabrication system where a process planning is performed to create instructions for LM machines. As a laser-based LM method, Direct Metal Deposition (DMD) at the University of Michigan is briefly described. A specific example (FGM pressure vessel) is shown to illustrate the entire FEA-based design and DMD fabrication cycle.
Two Fixations Suffice in Face Recognition (2008)

It is well known that there exist preferred landing positions for eye fixations in visual word recognition. However, the existence of preferred landing positions in face recognition is less well established. It is also unknown how many fixations are required to recognize a face. To investigate these questions, we recorded eye movements during face recognition. During an otherwise standard face-recognition task, subjects were allowed a variable number of fixations before the stimulus was masked. We found that optimal recognition performance is achieved with two fixations; performance does not improve with additional fixations. The distribution of the first fixation is just to the left of the center of the nose, and that of the second fixation is around the center of the nose. Thus, these appear to be the preferred landing positions for face recognition. Furthermore, the fixations made during face learning differ in location from those made during face recognition and are also more variable in duration; this suggests that different strategies are used for face learning and face recognition.
Broadband Pockels cell and driver for a Mark III-type free electron laser (1994)

A Pockels cell with an operating range of 2 to 10 μm has been designed, constructed, and tested for use with the Vanderbilt free electron laser. The Pockels cell can be continuously adjusted to switch out from 80 ns to the full 6 μs duration of the FEL macropulse. The extinction ratio is better than 180:1 and the optical pulse is square with rise and fall times under 10 ns. The high voltage drivers are based on semiconductor switches that are compact and mounted directly to the Pockels cell; this design avoids problems associated with fast, high voltage pulses traveling in cables. In addition, designs for two alternative drivers to generate optical pulses with durations ranging from a few nanoseconds down to the subnanosecond regime are presented here. Prototypes using single high voltage transitions have been constructed and tested electrically.
The comparative cost of associative memory (1976)

The production cost-per-bit of high-speed associative memory, implemented with m.o.s. l.s.i. content addressable memory (c.a.m.) devices (selected from a survey of 20 designs), is compared with that of conventional memory, implemented with currently available m.o.s. l.s.i. random access memory (r.a.m.) devices.For a development cost of about £20k, the cost-perbit of the m.o.s. c.a.m.s is about 5× that of a 1024-bit p-channel m.o.s. dynamic r.a.m. and about 9× that of a 4096-bit n-channel m.o.s. dynamic r.a.m., if plastic dual-in-line packaging is employed. However, for open-chip (beam-lead or flip-chip) assembly the cost-per-bit of the m.o.s. c.a.m.s is less than 2× that of the 1024-bit r.a.m. and less than 3× that of the 4096-bit r.a.m.It is shown that for most associative processing applications the associative memory can provide a cheaper alternative to conventional r.a.m.-based computer systems.
Surface modification of poly(methyl methacrylate) for improved adsorption of wall coating polymers for microchip electrophoresis (2006)

The development of rapid and simple wall coating strategies for high-efficiency electrophoretic separation of DNA is of crucial importance for the successful implementation of miniaturized polymeric DNA analysis systems. In this report, we characterize and compare different methods for the chemical modification of poly(methyl methacrylate) (PMMA) surfaces for the application of wall coating polymers. PMMA surfaces coated with 40 mol% diethylacrylamide and 60 mol% dimethylacrylamide are compared to the PMMA surfaces first oxidized and then coated with hydroxypropylmethyl-cellulose or poly(vinyl alcohol) (PVA). PMMA oxidation was accomplished with UV/ozone or an aqueous solution of HNO(3) to yield hydrogen-bond donors for the spontaneous adsorption of the coating polymers. Contact angle measurements of UV/ozone exposed PMMA surfaces indicate increase in hydrophilicity, and polymer coated surfaces show a strong dependence on the coating polymer and the oxidation method. Fast and repeatable electrophoretic separations of a 10-base and 20-base DNA ladder were performed in PMMA micro CE devices. All analyses were completed in less than 10 min, resulting in the number of theoretical plates as high as 583 000 in a 7.7 cm long separation channel. The duration of UV/ozone treatment was found to have a considerable impact on separation performance. The microchips irradiated with UV for 10 min and coated with PVA as well as the microchips treated with HNO(3) and coated with HPMC were found to have the best separation performance. These results demonstrate facile and robust methods for the surface modification of PMMA enabling low-cost single use devices for electrophoretic DNA separations.
A Dedicated Graphics Processor SIGHT-2 (1989)

SIGHT-2 is a multiprocessor system that is intended to efficiently execute the ray tracing algorithm. To achieve high efficiency, three kinds of parallel execution mechanisms; (i) a multiprocessor configuration, (ii) a parallel execution of three dimensional vector operations, and (iii) functionally distributed parallel processing are introduced. Owing to the latter two techniques, each processing element (PE) has the ability to execute the standard ray tracing algorithm 10 times faster than a VAX11/780 with a floating point accelerator. In the present con­ figuration, SIGHT-2 utilizes 16 PEs, which results in a peak power of 66.72 MFLOPS / 133.28 MIPS. During ray tracing, the efficiency of each PE is over 99% under static load balancing.In this paper, SIGHT-2 system architecture, its PE configuration, and VLSIs design are discussed. The system performance is also discussed.
An intron nucleotide sequence variant in a cloned β<sup>+</sup>-thalassaemia globin gene (1981)

A 7.5 kb Hsu I restriction fragment of genomic DNA containing a beta-globin gene has been isolated from a patient doubly heterozygous for beta + thalassaemia and a delta beta (Lepore globin fusion gene. This fragment must be derived from the chromosome carrying the beta +-thalassaemia determinant. The gross structure of the cloned gene plus flanking sequences is indistinguishable from that of a normal beta-globin gene. Within in 1606 base-pair transcribed region of the gene there is only one nucleotide difference from the normal beta-globin gene sequence. This is a G leads to A replacement 21 nucleotides upstream from the 3' terminus of the small intron. This nucleotide lies within a 10 base-pair sequence repeated in an inverted configuration near the 5' terminus of the small intron. The nucleotide replacement may result in a precursor mRNA less amenable to RNA splicing than its normal counterpart.

Representing the city: Complementing science and technology with art (2015)

Understanding how technology works is imp01tant, but the pattnership between ati and science, and their contributions to the discipline, are as important. Art provides the 'public face' of cartography (and if we include the caitographer's passion when designing particular products, perhaps the soul as well), and science complements this by ensuring that what is presented is scientifically correct and what could be called 'scientifically elegant' as well.
CTP-WUR: The collection tree protocol in wake-up radio WSNs for critical applications (2016)

Allowing the nodes of a wireless sensor network (WSN) to turn their radio off periodically noticeably increases network lifetime. Duty cycling, however, does not eliminate idle listening, comes at the price of longer latencies and obtains lifetimes that are still insufficient for many critical applications. Using a wake-up receiver (WUR) allows actual communications on the main radio only for transmission or reception, virtually eliminating node idling. However, the range of current WUR prototypes is still significantly shorter than that of the main radio, which can challenge the use of existing WSN protocols in WUR-based networks. In this paper we present an approach to mitigate this limitation of wake-up-based networks. In particular, we show that the Collection Tree Protocol (CTP), a standard protocol for data gathering in WSNs, suitably redefined to work on WUR-endowed nodes, achieves lifetimes of several decades. This constitutes a remarkable improvement over duty cycle-based solutions, where CTP makes the network lasts only a handful of months. At the same time, our WUR-based approach obtains data latencies comparable to those obtained by keeping the main radio always on.
Training System for Manual Arc Welding by Using Mixed Reality (2006)

A simulator for training manual arc welding operation by means of mixed reality technique was proposed and discussed in the previous paper. According to the experimental training results with the simulator in it, most trainees could not gain the skill of electrode tip positioning so well, though they could gain the skill of moving speed and angle control of the electrode. In this research, the authors investigate the reason for the less effectiveness and the solutions. As the results, it is found that in the conventional system, the trainees have difficulty in perception of electrode tip position, because of its inaccurate drawing in the real environmental image and two dimensional visual displaying. To improve the drawing accuracy, the camera for video-see-through HMD is replaced with high resolution ones and the multimarker position detection system is adopted. In addition, a stereo vision HMD with an easy vergence angle adjustment function is adopted to give the trainees three dimensional image. The experiments with the improved simulator show apparent reduction of the position-perception error of electrode tip and effective training.
Arabic revolutions impact on Turkish foreign policy (Based on Role theory) (2016)

The principle of non-interference in the Middle Eastern issues was the priority of Turkeys foreign policy strategy during most of the twentieth century. However, over the past decade, Turkey has considerably distanced from its Kemalist and introspective tradition and has become one of the active and inﬂuential actors in the region. Consequently, subsequent to the Justice and Development Party coming to power in 2002, Turkey in the framework of the strategy of zero problems with neighbors, established closer relationships with its ancient rivals, namely Syria, Iran and Iraq, adopted the leadership role in the Organization of Islamic Cooperation, attended the Arab League conferences and helped United Nations Interim Forces in Lebanon. In the same vein, Ankara took on the role of mediator in resolving disputes between Israel and Syria (2008-2010) as well as Irans nuclear ﬁle. Thus, the question is that, based on such an approach, how can this new Turkish foreign policy be described and understood towards recent developments in the region.Therefore, it is tried to study the foreign policymaking of Turkey within the framework of Role Theory through the main question: what are the impacts of Arab Revolutions on the role conceptions of Turkish foreign policymaking in the Middle East? Accordingly, the hypothesis of this research is the Arab Revolutions have resulted in the national role conceptions of Turkey in regard to the Middle East.Thus, this article is an attempt to enlighten the roles of Turkey in its new foreign policy-making in the region and towards the recent uprisings in the Middle East through addressing the underneath effective layers that changed Turkey from its previous strategy.
