Disaggregation and Sharing of I/O Devices in Cloud Data Centers (2015)

Input/output (I/O) devices such as a graphics processing unit and a solid-state drive are inserted into I/O slots of a host in data center platforms. With this sort of configuration the I/O devices are used exclusively by the host with resultant inefficient resource usage. In addition, the maximum number of I/O devices that can be assigned to each host is limited by the number of its I/O slots. This paper proposes a method to solve the resource usage inefficiency and assignment limitation by disaggregating I/O devices from hosts. An I/O device accommodated in a device pool is interconnected with multiple hosts by a standard Ethernet and can be flexibly assigned to one of them. Introducing assignment flexibility of I/O devices among hosts improves the resource usage efficiency and enables as many I/O devices as desired being assigned to each host. The authors further propose a method that enables an I/O device to be simultaneously shared among multiple hosts and multiple I/O packets to be aggregated into an Ethernet frame to suppress the performance overhead of the device disaggregation. Evaluation results showed that I/O devices that are compliant to PCI Express are shared with the overhead up to 27 percent.
A micro-patterned silicon chip as sample holder for macromolecular crystallography experiments with minimal background scattering (2015)

At low emittance synchrotron sources it has become possible to perform structure determinations from the measurement of multiple microcrystals which were previously considered too small for diffraction experiments. Conventional mounting techniques do not fulfill the requirements of these new experiments. They significantly contribute to background scattering and it is difficult to locate the crystals, making them incompatible with automated serial crystallography. We have developed a micro-fabricated sample holder from single crystalline silicon with micropores, which carries up to thousands of crystals and significantly reduces the background scattering level. For loading, the suspended microcrystals are pipetted onto the chip and excess mother liquor is subsequently soaked off through the micropores. Crystals larger than the pore size are retained and arrange themselves according to the micropore pattern. Using our chip we were able to collect 1.5 Å high resolution diffraction data from protein microcrystals with sizes of 4 micrometers and smaller.

Proceedings of the first workshop on Information and knowledge management for developing region (2012)

It is our great pleasure to welcome you to the First Workshop on Information and Knowledge Management for Developing Regions, IKM4DR'12. This workshop aims to bring the data management, information retrieval, and knowledge management communities together around questions of technology support for societal development. Our twin goals are to help to identify new applications for existing information and knowledge management technologies in developing regions and to inspire new research on problems that arise in developing region contexts. We anticipate a mix of industrial and academic participation.

The workshop call was focused on three main themes:

Components: Development of tools for low-resource languages that have the potential to transform information and knowledge management for those languages.

Applications: Ways of employing new and existing data management, information retrieval and knowledge management technology to novel and important challenges that arise in the context of developing regions.

Fostering adoption: Working together with partners from developing regions to craft solutions that embed societal expectations and values in ways that make it possible to achieve the envisioned impact.

The call for papers attracted 10 submissions from India, China, Japan, and the United States. The program committee accepted 7 papers that cover a variety of topics, including voice search systems, domain specific search for low-resource languages and several applications in developing regions with respect to content management. In addition, the program includes invited talk on Text Books for Developing Regions, and a keynote speech by Ricardo Baeza-Yates. We hope that these proceedings will serve as a valuable reference for researchers and developers who are looking to bventure in the area of applying technologies for developing regions.
Nonlinear damping in vehicle lateral control: theory and experiment (1998)

The sensor and actuator limits in real-world control systems imposes unavoidable tradeoffs between performance and the size of the operating region. When linear control design techniques are used, these limits are either neglected or accounted for by lowering the gains of the controller. The former results in severe reduction of the operating region, while the latter yields low performance. These tradeoffs can often be mitigated by using a nonlinear control strategy, in which nonlinear terms are intentionally introduced in order to implement different design objectives in different operating regions. In this paper, nonlinear damping is utilized as a design tool in lateral control of automated vehicles. Design considerations of the vehicle lateral controller include lateral tracking errors, passenger ride quality and reference/sensing system characteristics. It is shown that the intentionally introduced nonlinear damping term in the feedback loop possesses several favorable design features in the lateral control system. Experimental results using a full scale automated vehicle show that passenger comfort can be enhanced for small errors by significantly reducing the original controller gains, while at the same time achieving the same level of maximum lateral tracking errors.
Decomposition of the time-reversal operator applied to quantitative characterization of small elastic cylinders (2006)

Recent experiments showed how the DORT method can be used for the characterization of elastic cylinders imbedded in water (Minonzio et al., J. Acoust. Soc. Am. 117 (2), pp 789-798, 2005). Here, the small cylinder limit (k0a < 0.5) is considered. The singular values of the array response matrix are studied. It is show that the first singular value is proportional to k0(α + β)a 2 and the second one is proportional to k0βa 2 where a is the radius, α is the compressibility contrast, β is the density contrast between the cylinder and the fluid. Thus, the linear frequency dependence of the two singular values provides two equations with three unknowns, α, β and a. If one of these three parameters is known (for example, α is about 1 for metals), the other two can be determined. Measurements carried out for materials of α ranging from 0.6 to 0.99 and β between 0.1 and 1.6 are presented. A good agreement between calculated and experimental singular values was observed. Generalized expressions of the two first singular values are also given for k0a < 10. The analysis of acoustic scattering is an important tool for object identification. It has applications among non-destructive evaluation, medical imaging or underwater acoustics. The decomposition of the time-reversal operator (DORT method in French) is a new approach to scattering analysis that was developed since 1994 and is applied to detection and selective focusing through non-homogeneous media with array of transducers (1). The principle is the analysis of the complete set of pulse echo responses of the array. The eigenvalues and the eigenvectors of the time-reversal operator (i.e., singular values and singular vectors of the array response matrix) provide information on the scatterers in the insonified medium. Recent experiments showed how the DORT method can also be used for the characterization of sub-wavelength scatterers (2),(3), as elastic cylinders (4), imbedded in water. It has been shown that a single elastic scatterer is generally associated to several singular values and that the singular vectors are combinations of the projection on the array of the normal modes of vibrations (monopolar, dipolar, quadripolar...). After a brief presentation of these recent results, we focus on the case of small cylinder (k0a < 0.5), for which the two first normal modes are preponderant. The singular values and the singular vectors of the array response matrix are calculated and experimentally observed. We show that there are two preponderant singular values and study their dependence on the geometrical parameters, the cylinder radius a, the compressibility contrast α, and the density contrast β between the cylinder and the fluid. We present experimental results obtained in the MHz range for cylinders of different material and diameters using 96 transducers array. We also propose generalized expressions of the two first singular values, valid for k0a < 10.
On improving the fairness of TCP congestion avoidance (2002)

We report on a simulation-based study of the efficacy of modified congestion avoidance algorithms on TCP fairness. We first examined whether a change to that algorithm, as proposed by Floyd (1991), that results in a "constant-rate" additive increase policy can correct the bias against connections with long round trip times (RTTs). Our first main result is that although the constant-rate policy can improve fairness dramatically, we found it difficult to successfully implement such a policy in a heterogeneous network. Next, we explored whether TCP connections with long RTTs could independently improve their own throughputs by becoming slightly more aggressive during the additive increase phase of congestion avoidance. Our second main result is that the judicious use of such a policy is beneficial for long RTT connections, without significantly affecting the performance of peer connections along the same path, thereby improving our metric of network fairness without compromising the utilization of the bottleneck link.
Dopaminergic Signaling in the Cochlea: Receptor Expression Patterns and Deletion Phenotypes (2012)

Pharmacological studies suggest that dopamine release from lateral olivocochlear efferent neurons suppresses spontaneous and sound-evoked activity in cochlear nerve fibers and helps control noise-induced excitotoxicity; however, the literature on cochlear expression and localization of dopamine receptors is contradictory. To better characterize cochlear dopaminergic signaling, we studied receptor localization using immunohistochemistry or reverse transcriptase PCR and assessed histopathology, cochlear responses and olivocochlear function in mice with targeted deletion of each of the five receptor subtypes. In normal ears, D1, D2, and D5 receptors were detected in microdissected immature (postnatal days 10-13) spiral ganglion cells and outer hair cells but not inner hair cells. D4 was detected in spiral ganglion cells only. In whole cochlea samples from adults, transcripts for D1, D2, D4, and D5 were present, whereas D3 mRNA was never detected. D1 and D2 immunolabeling was localized to cochlear nerve fibers, near the first nodes of Ranvier (D2) and in the inner spiral bundle region (D1 and D2) where presynaptic olivocochlear terminals are found. No other receptor labeling was consistent. Cochlear function was normal in D3, D4, and D5 knock-outs. D1 and D2 knock-outs showed slight, but significant enhancement and suppression, respectively, of cochlear responses, both in the neural output [auditory brainstem response (ABR) wave 1] and in outer hair cell function [distortion product otoacoustic emissions (DPOAEs)]. Vulnerability to acoustic injury was significantly increased in D2, D4 and D5 lines: D1 could not be tested, and no differences were seen in D3 mutants, consistent with a lack of receptor expression. The increased vulnerability in D2 knock-outs was seen in DPOAEs, suggesting a role for dopamine in the outer hair cell area. In D4 and D5 knock-outs, the increased noise vulnerability was seen only in ABRs, consistent with a role for dopaminergic signaling in minimizing neural damage.
Nonlinear Group IV photonics based on silicon and germanium: from near‐infrared to mid‐infrared (2013)

Abstract Group IV photonics hold great potential for nonlinear applications in the near‐ and mid‐infrared (IR) wavelength ranges, exhibiting strong nonlinearities in bulk materials, high index contrast, CMOS compatibility, and cost‐effectiveness. In this paper, we review our recent numerical work on various types of silicon and germanium waveguides for octave‐spanning ultrafast nonlinear applications. We discuss the material properties of silicon, silicon nitride, silicon nano‐crystals, silica, germanium, and chalcogenide glasses including arsenic sulfide and arsenic selenide to use them for waveguide core, cladding and slot layer. The waveguides are analyzed and improved for four spectrum ranges from visible, near‐IR to mid‐IR, with material dispersion given by Sellmeier equations and wavelength‐dependent nonlinear Kerr index taken into account. Broadband dispersion engineering is emphasized as a critical approach to achieving on‐chip octave‐spanning nonlinear functions. These include octave‐wide supercontinuum generation, ultrashort pulse compression to sub‐cycle level, and mode‐locked Kerr frequency comb generation based on few‐cycle cavity solitons, which are potentially useful for next‐generation optical communications, signal processing, imaging and sensing applications.
Global extracellular volume (ECVglobal) in HCM - the “next generation” test for risk in hypertrophic cardiomyopathy? (2013)

Background CMR LGE detects myocardial tissue abnormalities in hypertrophic cardiomyopathy (HCM) and aids in risk stratification, predicting in particular heart failure and to a lesser extent, sudden death. However, LGE quantifies only the area of focal fibrosis only, missing diffuse fibrosis and assuming all LGE is the same. We hypothesized that the total left ventricular fibrosis burden, as measured by the mean global myocardial extracellular volume (ECVglobal) using 16 segment T1 mapping, would be a superior marker.
Efficacy of Digital Outreach Strategies for Collecting Smoking Data: Pragmatic Randomized Trial (Preprint) (2023)

<sec> <title>BACKGROUND</title> Tobacco smoking is an important risk factor for disease, but inaccurate smoking history data in the electronic medical record (EMR) limits the reach of lung cancer screening (LCS) and tobacco cessation interventions. Patient-generated health data is a novel approach to documenting smoking history; however, the comparative effectiveness of different approaches is unclear. </sec> <sec> <title>OBJECTIVE</title> We designed a quality improvement intervention to evaluate the effectiveness of portal questionnaires compared to SMS text message–based surveys, to compare message frames, and to evaluate the completeness of patient-generated smoking histories. </sec> <sec> <title>METHODS</title> We randomly assigned patients aged between 50 and 80 years with a history of tobacco use who identified English as a preferred language and have never undergone LCS to receive an EMR portal questionnaire or a text survey. The portal questionnaire used a “helpfulness” message, while the text survey tested frame types informed by behavior economics (“gain,” “loss,” and “helpfulness”) and nudge messaging. The primary outcome was the response rate for each modality and framing type. Completeness and consistency with documented structured smoking data were also evaluated. </sec> <sec> <title>RESULTS</title> Participants were more likely to respond to the text survey (191/1000, 19.1%) compared to the portal questionnaire (35/504, 6.9%). Across all text survey rounds, patients were less responsive to the “helpfulness” frame compared with the “gain” frame (odds ratio [OR] 0.29, 95% CI 0.09-0.91; &lt;i&gt;P&lt;/i&gt;&amp;lt;.05) and “loss” frame (OR 0.32, 95% CI 11.8-99.4; &lt;i&gt;P&lt;/i&gt;&amp;lt;.05). Compared to the structured data in the EMR, the patient-generated data were significantly more likely to be complete enough to determine LCS eligibility both compared to the portal questionnaire (OR 34.2, 95% CI 3.8-11.1; &lt;i&gt;P&lt;/i&gt;&amp;lt;.05) and to the text survey (OR 6.8, 95% CI 3.8-11.1; &lt;i&gt;P&lt;/i&gt;&amp;lt;.05). </sec> <sec> <title>CONCLUSIONS</title> We found that an approach using patient-generated data is a feasible way to engage patients and collect complete smoking histories. Patients are likely to respond to a text survey using “gain” or “loss” framing to report detailed smoking histories. Optimizing an SMS text message approach to collect medical information has implications for preventative and follow-up clinical care beyond smoking histories, LCS, and smoking cessation therapy. </sec>
Frequency modulation multiplexing for simultaneous detection of multiple gases by use of wavelength modulation spectroscopy with diode lasers (1998)

Modulation frequency multiplexing provides a straightforward method, analogous to television or radio broadcasting, for performing simultaneous detection of multiple gases by use of wavelength modulation spectroscopy with diode lasers. When fiber-optic coupled lasers are used, our approach guarantees that all beams transit the same optical path and impinge on the same detector. Each laser is modulated at a different frequency and the detector output is processed by a set of lock-in amplifiers, one for each laser, to measure the absorbance encountered by each laser.
Mitigation of SARS-CoV-2 by Using Transition Metal Nanozeolites and Quaternary Ammonium Compounds as Antiviral Agents in Suspensions and Soft Fabric Materials (2023)

This study shows the efficacy of transition metal nanozeolite formulations as novel antiviral agents and establishes that nanozeolite with silver and zinc ions (AM30) and nanozeolite with silver and copper ions (AV30) when combined with benzalkonium nitrate (BZN) quickly and continuously inactivate SARS-CoV-2 in suspension and on fabric materials.
Improving processor performance by simplifying and bypassing trivial computations (2003)

During the course of a program's execution, a processor performs mangy trivial computations; that is, computations that can be simplified or where the result is zero, one, or equal to one of the input operands. This paper shows that, despite compiling a program with aggressive optimizations (-O3), approximately 30% of all arithmetic instructions, which account for 12% of all dynamic instructions, are trivial computations. The amount of trivial computation is not heavily dependent on the program's specific input values. Our results show that eliminating trivial computations dynamically at run-time yields an average speedup of 8% for a typical processor. Even for a very aggressive processor (i.e. one with no functional unit constraints), the average speedup is still 6%. It also is important to note that the area cost (i.e. hardware) required to dynamically detect and eliminate these trivial computations is very low, consisting of only a few comparators and multiplexers.
Speaker adaptive training: a maximum likelihood approach to speaker normalization (2002)

This paper describes the speaker adaptive training (SAT) approach for speaker independent (SI) speech recognizers as a method for joint speaker normalization and estimation of the parameters of the SI acoustic models. In SAT, speaker characteristics are modeled explicitly as linear transformations of the SI acoustic parameters. The effect of inter-speaker variability in the training data is reduced, leading to parsimonious acoustic models that represent more accurately the phonetically relevant information of the speech signal. The proposed training method is applied to the Wall Street Journal (WSJ) corpus that consists of multiple training speakers. Experimental results in the context of batch supervised adaptation demonstrate the effectiveness of the proposed method in large vocabulary speech recognition tasks and show that significant reductions in word error rate can be achieved over the common pooled speaker-independent paradigm.
