Sensing and control in bandwidth-limited systems: A Kalman filter approach (2008)

Cooperative systems, like those found in networks of unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs), are typically distributed over large geographical areas. This geographic dispersion forces reliance on wireless communications to implement the control systems for these networks. As the number of nodes within the system grows, the bandwidth required to continuously update all nodes exceeds available bandwidth. This forces the system engineers to implement a prioritization scheme to determine which nodes will be updated during each frame. In this paper, we consider the design of protocols to prioritize the communications of sensing and control data. We consider a control system that uses a Kalman filter to supply optimal estimates of the positions for a group of maneuvering targets in the presence of measurement noise and lost data. The filter innovations provide estimates of the magnitude of statistical deviations from the state estimates, as well as deviations from planned profiles. Thus, we propose protocols that use the filter innovations to prioritize the sensing and control traffic. We compare the performance of this approach to a round-robin protocol and to the performance of a Kalman filter with no bandwidth constraints. We show that using the filter innovations offers a significant performance improvement over the round-robin protocol.
Understanding how the projection of availability state impacts the reception incoming communication (2013)

Many communication systems infer and project information about a user's availability, making it possible for others to decide whether and how to contact that user. Presumably when the system infers people are busy, they are less open to interruption. But analysis of 103,962 phone calls made using a popular enterprise communications tool reveals that people are actually significantly more likely to answer the phone when the system projects that they are busy than at other times. A follow-up survey of 569 users of the system suggests that this seemingly counter-intuitive fact may arise because people care a lot about the recipient's availability when initiating phone communications and are unlikely to attempt to call someone who appears to be busy unless the communication is important. Recipients thus perceive incoming calls as more important when they are busy than at other times, making them more likely to answer.
Quantum algorithm for designing multi-reflector resonant bandpass filters (2005)

Quantum operator algebra related to Jaynes-Cummings model is developed to design multi-reflector resonant bandpass filters for the first time. Transmittance and reflectance spectra of these filters are givens with analytic expressions. The results are found in agreement with those based on the existing filter design method. By selecting parameters such as <i>r</i> and N, designed filters can achieve a target spectrum profile with flat-top, large bandwidth, and minor ripples.
Occurrence of Histamine‐Forming Bacteria in Albacore and Histamine Accumulation in Muscle at Ambient Temperature (2002)

ABSTRACT Distribution of histamine‐producing bacteria in fresh albacore and their proliferation in muscle during storage at 25 °C were monitored. Histamine formers constituted a minor portion of the bacterial flora in albacore. Only weak histamine formers were detected in the gill and skin of fresh fish after enrichment. Histamine formers were isolated from the muscles when APC reached >10 7 CFU/g during storage. Hafnia alvei was most prevalent in both fresh and temperature‐abused fish. The most prolific histamine former, Morganella morganii , was rarely isolated even from spoiled muscles. The prevalence of weak histamine formers resulted in low levels of histamine accumulation in muscle, 67.1 mg/100 g, for 6 d of storage.
<title>Coarse-to-fine strategy for motion estimation</title> (1993)

In this paper, we describe a hierarchical framework for the computation of displacement fields from a sequence of images acquired by a moving camera and containing several moving objects. We also describe a matching algorithm which is consistent with the proposed framework and we present some experimental results demonstrating the robustness of our approach.
Searching for evidence of DFNB2 (2002)

Deafness is the most common form of sensory impairment in humans, affecting about 1 in 1,000 births in the United States. Of those cases with genetic etiology, approximately 80% are nonsyndromic and recessively inherited. Mutations in several unconventional myosins, members of a large superfamily of actin-associated molecular motors, have been found to cause hearing loss in both humans and mice. Mutations in the human unconventional Myosin VIIa (MYO7A), located at 11q13.5, are reported to be responsible for both syndromic and nonsyndromic deafness. MYO7A mutations are responsible for Usher syndrome type Ib, the most common genetic subtype of Usher I. Usher I is clinically characterized by congenital profound deafness, progressive retinal degeneration called retinitis pigmentosa (RP), and vestibular areflexia. Although a wide spectrum of MYO7A mutations have been identified in Usher Ib patients, four mutations have been reported to cause DFNB2, a recessive deafness without retinal degeneration, and one mutation has been implicated in a single case of dominant nonsyndromic hearing loss (DFNA11). Our study attempts to ascertain additional DFNB2 families to investigate the disparate nonsyndromic phenotype and alleged causative mutations. Data from both linkage and heterogeneity analyses on 36 selected autosomal recessive nonsyndromic deafness (RNSD) families, all previously excluded by mutational analysis from GJB2 (Cx26), the leading cause of nonsyndromic deafness, showed no evidence of DFNB2 within the sample. These negative results and the isolated reports of DFNB2 bring into question whether certain MYO7A mutations produce nonsyndromic recessive hearing loss.
Enantioselective Sulfoxidation and Kinetic Resolution Combined Protocol Mediated by a Functionalized (<i>S</i>)‐Norcamphor‐Based Hydroperoxide/Titanium(<scp>IV</scp>) Isopropoxide System (2007)

Abstract A functionalized tertiary furyl hydroperoxide derived from ( S )‐norcamphor has been easily synthesized in good yield and in a highly diastereoselective manner. Good to high enantioselectivities (up to 99 % ee ) and acceptable to good yields (up to 86 %) were achieved for the sulfoxides, by tandem stereoconvergent asymmetric sulfoxidation and kinetic resolution when using the novel hydroperoxide as oxygen donor and chirality source in the presence of catalytic loadings of titanium( IV ) isopropoxide as the catalyst.
Microcytotoxicity Test: Detection in Sarcoma Patients of Antibody Cytotoxic to Human Sarcoma Cells (1970)

A microcytotoxicity test has been used to detect a factor cytotoxic for human sarcoma cells; the factor was found in serums from 70 percent of sarcoma patients, 58 percent of their family members, and 8 percent of serums from normal blood donors. This cytotoxin is an antibody against a common cell surface sarcoma antigen since it is specific for sarcoma cells, is complement dependent, and is extractable with the globulin fraction of serum.
Vacuum polarization- and molecular-potential effects in heavy-ion scattering (1976)

The corrections to the heavy-ion scattering cross sections due to the presence of perturbing vacuum polarization and molecular potentials are evaluated. We find effects on the cross section up to 0.7% in $^{16}\mathrm{O}$ with $^{208}\mathrm{Pb}$ collisions due to vacuum polarization and up to 2.6% in U with Th collisions due to molecular and vacuum polarization corrections.NUCLEAR REACTIONS Calculations of modifications of elastic heavy-ion $\ensuremath{\sigma}(\ensuremath{\theta})$ due to vacuum polarization and molecular potentials.
Protective Efficacy and Long-Term Immunogenicity in Cynomolgus Macaques by Ebola Virus Glycoprotein Synthetic DNA Vaccines (2018)

These data support that this simple intradermal-administered, serology-independent approach is likely important for additional study towards the goal of induction of anti-EBOV immunity in multiple at-risk populations.
Learning to play partially-specified equilibrium (2007)

In a partially-specified correlated equilibrium (PSCE) the players are par-tially informed of the conditional strategies of the other players, and they best respond to the worst-case possible strategy. We construct a decentral-ized procedure that converges to PSCE when the monitoring is imperfect. This procedure is based on minimizing conditional regret when players obtain noisy signals that depend on the actions that have been previously played.

We look at a 15 years timeframe and discuss the scientific and technical progress in various domains as well as the ethical, legal, and policy dilemmas involved.
[Image guided and robotic treatment--the advance of cybernetics in clinical medicine]. (2000)

The introduction of advanced technology in hospitals has changed the treatment practice towards more image guided and minimal invasive procedures. Modern computer and communication technology opens up for robot aided and pre-programmed intervention. Several robotic systems are in clinical use today both in microsurgery and in major cardiac and orthopedic operations. As this trend develops, professions which are new in this context such as physicists, mathematicians and cybernetic engineers will be increasingly important in the treatment of patients.
Numerical Simulation of the Gas-Liquid Flow in a Rotary Gas Separator (1998)

The presence of free gas at the pump intake adversely affects the performance of an electrical submersible pump (ESP) system, often resulting in low efficiency and causing operational problems. One method of reducing the amount of free gas that the pump has to process is to install a rotary gas separator. The gas-liquid flow associated with the down hole installation of a rotary separator has been investigated to address its overall phase segregation performance. A mathematical model was developed to investigate factors contributing to gas-liquid separation and to determine the efficiency of the separator. The drift-flux approach was used to formulate this complex two-phase flow problem. The turbulent diffusivity was modeled by a two-layer mixing-length model and the relative velocity between phases was formulated based on published correlations for flows with similar characteristics. The well-known numerical procedure of Patankar-Spalding for single-phase flow computations was extended to this two-phase flow situation. Special discretization techniques were developed to obtain consistent results. Special under relaxation procedures were also developed to keep the gas void fraction in the interval [0, 1]. Predicted mixture velocity vectors and gas void fraction distribution for the two-phase flow inside the centrifuge are presented. The model’s predictions are compared to data gathered on a field scale experimental facility to support its invaluable capabilities as a design tool for ESP installations.

A high gain-bandwidth product transimpedance amplifier for MEMS-based oscillators (2008)

A variable gain differential transimpedance amplifier (TIA) optimized for MEMS-based oscillator applications is presented. The TIA achieves a variable gain of 17 kOmega to 290 kOmega, i.e. a gain range of 25 dB. The 3-dB bandwidths corresponding to these gains are 256 MHz and 103 MHz, respectively. The suitability of the TIA for the targeted application is demonstrated by combining it with a MEMS resonator to create an oscillator at the frequency of 8.29 MHz, with a phase noise of -89 dBc/Hz at a 1 kHz offset frequency.
Noncontact Monitoring of Respiratory Rate in Newborn Infants Using Thermal Imaging (2018)

Monitoring of respiratory rate (RR) is very important for patient assessment. In fact, it is considered one of the relevant vital parameters in critical care medicine. Nowadays, standard monitoring relies on obtrusive and invasive techniques, which require adhesive electrodes or sensors to be attached to the patient's body. Unfortunately, these procedures cause stress, pain, and frequently damage the vulnerable skin of preterm infants. This paper presents a "black-box" algorithm for remote monitoring of RR in thermal videos. "Black-box" in this context means that the algorithm does not rely on tracking of specific anatomic landmarks. Instead, it automatically distinguishes regions of interest in the video containing the respiratory signal from those containing only noise. To examine its performance and robustness during physiological (phase A) and pathological scenarios (phase B), a study on 12 healthy volunteers was carried out. After a successful validation on adults, a clinical study on eight newborn infants was conducted. A good agreement between estimated RR and ground truth was achieved. In the study involving adult volunteers, a mean root-mean-square error (RMSE) of ( 0.31 ±0.09) breaths/min and ( 3.27 ±0.72) breaths/min was obtained for phase A and phase B, respectively. In the study involving infants, the mean RMSE hovered around ( 4.15 ±1.44) breaths/min. In brief, this paper demonstrates that infrared thermography might become a clinically relevant alternative for the currently available RR monitoring modalities in neonatal care.
Dark Photorefractive Spatial Solitons and Photorefractive Vortex Solitons (1995)

We report on the first experimental observations of dark, planar, spatial photorefractive solitons, and photorefractive vortex solitons that are trapped in a bulk (three-dimensional) photorefractive media. Both the dark and vortex solitons possess the ``signatures'' of the photorefractive solitons: they are independent of absolute intensity, can afford significant absorption, and are inherently asymmetric with respect to the transverse dimensions of trapping.
Bacteriorhodopsin D85N: Three spectroscopic species in equilibrium (1993)

Ground-state absorbance measurements show that BR from Halobacterium halobium containing asparagine at residue 85 (D85N) exists as three distinct chromophoric states in equilibrium. In the pH range 6-12 the absorbance spectra of the three states are demonstrated to be similar to flash-induced spectral intermediates which comprise the latter portion of the wild-type BR photocycle. One of the states absorbs maximally at 405 nm, has a deprotonated Schiff base, and contains predominantly the 13-cis form of retinal, identifying it as a close homologue of the M intermediate in the BR photocycle. The other species possess absorbance maxima with correspondence to those of the wild-type N (570 nm) and O (615 nm) photointermediates. The retinal composition of the O-like form was found to be dominated by all-trans isomer. The pH dependence of the concentrations of the equilibrium species corresponds closely with the pH dependence of the M, N, and O photointermediates. These data support kinetic models which emphasize the role of back-reactions during the photocycle of bacteriorhodopsin. Energetic and spectral characterization of the D85N ground-state equilibrium supports its use as a model for elucidating molecular transitions comprising the latter portion of the BR photocycle.
Adsorption and desorption properties of arsenate onto nano-sized iron-oxide-coated quartz (2010)

This study was conducted to investigate the adsorption and desorption properties of arsenate [As(V)] on nano-sized iron-oxide-coated quartz (IOCQ) through batch experiments. The coating of nano-sized iron oxide on the quartz surface was performed using the heat treatment process which aimed to utilize the adsorption properties of the nano-sized iron oxide and the filtration properties of the quartz. Environmental SEM-EDAX and BET techniques were used to analyze the surface morphology, elemental composition, surface area and the porosity of the adsorbent. SEM-EDAX analyses confirmed that arsenate was adsorbed on the IOCQ surface. BET results showed that the IOCQ adsorbent had higher pore volumes and high specific surface areas compared with the pure quartz. The study revealed that the adsorption rate of As(V) ion was very rapid and reached the equilibrium within 5 min. This study also revealed that almost 100% of As(V) removal was achieved within 5 minutes of adsorption reaction from the initial solution containing 1,000 microg-As(V)/L. The Langmuir adsorption isotherm model suitably explained the sorption characteristics of As(V) onto IOCQ. This desorption study showed that the adsorbent could be reused after reacting with mild HCl solution but the concentration of acid eluant or pH has a great impact on the coated adsorbent surface. The results indicate that the nano-sized iron oxide-coated adsorbent is potentially suitable for removal of arsenate from drinking water.
The Crura and Crura-Sphincter Pressure Dynamics in Patients with Isolated Upright and Isolated Supine Reflux (2001)

The reason why patients with isolated supine reflux do not reflux in the upright position and patients with isolated upright reflux do not reflux in the supine position is unknown. Our objective was to determine the characteristics of the crura, lower esophageal sphincter, crura-sphincter dynamics, and esophageal body on manometry, endoscopy, and X-ray in patients with isolated upright and isolated supine reflux. Eighty consecutive patients with isolated upright reflux were compared with 82 consecutive patients with isolated supine reflux. Manometrically there was no difference in lower esophageal sphincter characteristics and esophageal contractions between the two groups. The prevalence of a hiatal hernia on manometry was similar between upright and supine refluxers (88% vs 88%). Upright refluxers had shorter hiatal hernias [median (interquartile range) 1.1 (0.65-1.8) vs 1.2 (1-2.3), P < 0.046)]. The median crural pressure, crura-sphincter pressure gradient, and crura-sphincter pressure ratio in upright refluxers was 14.96 (9.5-21.27), 3.28 (1.7-12.2), and 1.33 (0.87-2.8) mm Hg, respectively. These values were significantly higher (P < 0.001) in supine refluxers at 21.43 (16.6-29.9), 10.66 (4.3-19.7), and 2.1 (1.3-4.2) mm Hg, respectively. We conclude that the significantly higher crural pressure in patients with supine reflux acts as a mechanical ring and as a physiologic protector against the unfolding of the sphincter in the postprandial and upright periods. Higher crura-sphincter pressure gradient and larger-size hiatal hernias in patients with supine reflux results in pressurization of the hernia sac and subsequent reflux when these patients are in a supine position.

Evaluation of Akt/mTOR activity in muscle atrophy after rotator cuff tears in a rat model (2012)

Abstract Atrophy of the rotator cuff muscles is a factor that complicates the treatment of a massive rotator cuff tear (RCT). However, the molecular mechanisms that govern the development of muscle atrophy after RCTs have not been well defined. The Akt/mammalian target of rapamycin (mTOR) signaling pathway plays a central role in maintaining muscle mass in response to mechanical loading. The role of this pathway in the development of muscle atrophy after a massive RCT remains unknown. The purpose of this study was to investigate the regulation of the Akt/mTOR pathway in the development of muscle atrophy after a RCT and suprascapular nerve (SSN) injury. We evaluated the activity of the Akt/mTOR signaling pathway and how this pathway interacts with two atrophy‐related genes, MuRF‐1 and MAFbx, in supraspinatus muscles of rats that underwent unilateral complete rotator cuff tendon transection or SSN transection. Akt/mTOR activity was significantly reduced after tendon rupture, but increased after nerve injury. MuRF‐1 and MAFbx were only up‐regulated following denervation. These results suggest that tendon transection leads to a decrease in protein synthesis with down‐regulation of the Akt/mTOR signaling pathway, whereas denervation leads to an increase in protein degradation via up‐regulation of expression of MuRF‐1 and MAFbx. © 2012 Orthopaedic Research Society.

Collection of a Chinese Spontaneous Telephone Speech Corpus and Proposal of Robust Rules for Robust Natural Language Parsing (2002)

In this paper, a Chinese Spontaneous Telephone Speech Corpus in the flight enquiry and reservation domain (CSTSC-Flight) of 6 GB raw data containing about 50 hours’ valid speech is introduced, including the collection and transcription principles and outline. Analysis on the spoken language phenomena contained in this corpus is then performed. Based on this, four types of grammatical are proposed so as to cover as many Chinese spoken language phenomena as possible for robust natural language parsing and understanding in spoken dialogue systems.
