Theory and applications of InfraRed and thermal image analysis in ergonomics research (2022)

Designing products and services to fit human needs, wants and lifestyle require meaningful data. With Industry 4.0 and the internet of things, we have many ways to capture data using sensors and other means. InfraRed (IR) cameras are quite ubiquitous, especially for screening illness and wellness. They can provide a wealth of data on different objects and even people. However, their use has been limited due to processing complexities. With reducing cost and increasing accuracy of IR cameras, access to thermal data is becoming quite widespread, especially in medicine and people-related applications. These cameras have software to help process the data, with a focus on qualitative analyses and rather primitive quantitative analyses. In ergonomics, data from multiple users are essential to make reasonable predictions for a given population. In this study, using 4 simple experiments, several quantitative analysis techniques such as simple statistics, multivariate statistics, geometric modeling, and Fourier series modeling are applied to IR images and videos to extract essential user and population data. Results show that IR data can be useful to provide user and population data that are important for design. More research in modeling IR data and application software is needed for the increased application of IR information in ergonomics applications.
THE EFFECTS OF CENTRAL ADMINISTRATION OF ANGIOTENSIN II TYPE‐1 RECEPTOR ANTAGONIST, CV‐11974, IN NEPHRECTOMIZED SPONTANEOUSLY HYPERTENSIVE RATS (1994)

1. The role of the brain renin-angiotensin system in the pathogenesis of genetic hypertension was evaluated using a specific non-peptide angiotensin II type-1 receptor antagonist, TCV-116. 2. CV-11974 (active metabolite of TCV-116) was acutely injected either intravenously (i.v.) or intracerebroventricularly (i.c.v) in male spontaneously hypertensive rats (SHR; 12 week old). In separate groups of nephrectomized and sham-operated SHR, graded doses of CV-11974 were administered either i.v. or i.c.v. for 2 days using an osmotic minipump. In another group, the effects of nephrectomy on the depressor effect of chronic treatment with CV-11974 were investigated. Haemodynamics at three points: before infusion, before nephrectomy and 48 h after nephrectomy, were monitored. 3. Acute i.c.v. injection of CV-11974 decreased blood pressure in the presence of the kidney. Prolonged i.c.v. administration of the drug for 2 days decreased blood pressure even at the lowest dosage, which had no hypotensive effects when given i.v. The hypotensive effect of centrally administered CV-11974 was noted even 48 h after bilateral nephrectomy. 4. These results suggest that the brain renin-angiotensin system has a primary role in the maintenance of hypertension after eliminating the circulating renin-angiotensin system in SHR.
An under‐recognized phenomenon: Myocardial volume change during the cardiac cycle (2021)

Healthy human myocardium appears to decrease in volume during systole. This is seen in MRI studies and is clinically relevant, but this study demonstrates that this characteristic was also present but unrecognized in the existing echocardiography literature.
Toroidal nuclei of columnar lyotropic chromonic liquid crystals coexisting with isotropic phase (2022)

Nuclei of ordered materials emerging from the isotropic state usually show a shape topologically equivalent to a sphere; the well-known examples are crystals and nematic liquid crystal droplets. In this work, we explore experimentally and theoretically the nuclei of columnar lyotropic chromonic liquid crystal coexisting with the isotropic phase that are toroidal in shape. The geometry of toroids depends strongly on the molecular concentrations and presence of a crowding agent, polyethylene glycol. High concentrations result in thick toroids with small central holes, while low concentrations yield thin toroids with wide holes. The multitude of the observed shapes is explained by the balance of bending elasticity and anisotropic interfacial tension.
PASSENGER CAR NOISE -- DIESEL AND GASOLINE (1978)

A study of noise radiation from European passenger cars was made during 1977. Two cars were studied in detail over their operating ranges and an additional ten typical cars were briefly tested. Measurements of both the externally radiated noise and the interior noise levels were made in some detail for the main subject vehicles, and the techniques and results are briefly outlined in the paper. The effects of using different types of legislation procedure on the measured noise levels of the vehicles are also discussed.
Integration of SOA-ready networked embedded devices in enterprise systems via a cross-layered web service infrastructure (2007)

Today manufacturers require efficient reaction to critical events occurring at the shop floor. Therefore, device-level data needs to be integrated into business processes in a standardized and flexible way to avoid time-consuming media breaks. Current approaches are characterized by a late indication of changes in the production environment and a delayed implementation of changed production plans. As a solution, we propose a web service-based integration of enterprise systems with shop-floor activities, using SOA-ready networked embedded devices. We examine the requirements for the integration and derive an appropriate architecture that tries to close the integration gap. The timely provision of data, the impact of device-level information on business processes, as well as the direct bidirectional communication with device-level services promotes the vision of adaptive manufacturing and leads to reduced production costs.
An updated checklist of Meloidogyne Göldi, 1887 species, with a diagnostic compendium for second-stage juveniles and males (2020)

The cosmopolitan root-knot nematodes of the genus Meloidogyne are considered as the most important plant-parasitic nematodes damaging almost all higher plant species. This paper provides an updated checklist of 105 valid species of Meloidogyne, along with their synonyms and non-valid members. Furthermore, species are grouped based upon their diagnostic characteristics of second-stage juveniles (tail shape, tail length, stylet length and dorsal gland orifice (DGO) distance from stylet base) and males (number of lateral incisures, stylet length, DGO and spicules length).

Development of a laser radar system for automobiles (1992)

This report describes the development of an automotive radar system which uses a laser diode as a light source. The time taken for a laser beam to travel to a vehicle ahead and to be reflected back is used to calculate distances between vehicles. This information is further processed and compared with continuous calculations of safe distances. When the actual distance between vehicles becomes less than the estimated safe distance, an audio warning signal is issued to alert the driver.
Purification of superoxide dismutase from placental haemolisate blood: a simple and efficient method. (1993)

Superoxide dismutase functions as a scavenger of superoxide radical protecting living organisms. This enzyme has potential use as anti-inflammatory or anti-reperfusion injury drug. Here we present a simple and efficient SOD purification method from human placental blood. Superoxide dismutase from clarified haemolysed placental blood after chloroform and ethanol treatment was purified by DEAE-Sepharose, Phenyl-Sepharose chromatographies and cross flow ultrafiltration. The purified product is 98% pure by SDS-PAGE with 71% yield and specific activity of 2.8 x 10(5) U/mg protein.
Mechanical Properties of Li7La2.75Ca0.25Zr1.75Nb0.25O12 Garnet Electrolyte—a Preliminary Study of a Porous Layer Support All-Solid State Battery (2017)

In order to study the feasibility of porous layer supported all-solid state battery, mechanical properties including flexural strength, Young’s modulus, and hardness of Li 7 La 2.75 Ca 0.25 Zr 1.75 Nb 0.25 O 12 (LLCZN) were studied. The flexural strength of LLCZN with varies porosity and grain size was determined based on ASTM C1161. Young’s modulus and hardness was obtained through nanoindentation technique. The flexural strength of LLCZN with full density is ~150 MPa. The refinement of the grain size can further increase the flexural strength. The dense LLCZN garnet has a Young’s modulus of ~147.2±6.6 GPa and a hardness of ~13.9±1.4 GPa. Above results indicate that the LLCZN garnet has sufficient strength, stiffness, and hardness as the dense layer in a porous layer supported all-solid state battery.
Power dynamics in a low pressure capacitively coupled plasma discharge (2009)

A one-dimensional coupled particle-in-cell and fluid model is used to understand power dynamics at low gas pressures in a capacitively coupled Ar discharge. For the range of gas pressure (5–500 mTorr) and excitation frequency (30–120 MHz) examined, the electrons absorb power at the sheath edge during sheath expansion. Energetic electron beams are generated at the edge of the expanding sheath, which are responsible for plasma production and sustenance. These energetic electrons are able to reach the opposite sheath at low gas pressures and return some of their energy during deceleration in the sheath. As a result, peak electron density decreases significantly below 10 mTorr. Above 50 mTorr, peak electron density is relatively insensitive to pressure as beam electrons deposit most of their energy in the plasma bulk. Secondary electron emission is found critical for plasma sustenance at 30 MHz, while sheath electron heating is the dominant electron heating mechanism at higher frequencies.
Cell Transplantation Improves Ventricular Function After a Myocardial Infarction (2005)

Engrafted USSCs were detected in the infarct region 4 weeks after cell transplantation, and the implanted cells improved regional and global function of the porcine heart after a myocardial infarction. This study suggests that the USSC implantation will be efficacious for cellular cardiomyoplasty.
Revocable Group Signature with Constant-Size Revocation List (2015)

It is essential that a multi-user cryptographic primitive be revocable since a legitimate user may quit the organization, or may act on malicious intent, or the relevant key may be leaked. In the group signature context, usually the group manager publishes the revocation list that contains revocation tokens. Since signers/verifiers need to obtain the revocation list in each revocation epoch to generate/verify a group signature, a small-size revocation list is really important in practice. However, all previous revocable group signatures require at least an |$O(r)$|-size revocation list, where |$r$| is the number of revoked users. In this paper, we propose the first revocable group signature scheme with a constant-size revocation list using identity-based revocation (IBR) techniques. We use an IBR scheme proposed by Attrapadung–Libert–Panafieu (PKC 2011) as a building block. As in the Libert–Peters–Yung schemes (EUROCRYPT 2012/CRYPTO 2012), no signing key update is required. In addition, the verification cost does not depend on the number of revoked users |$r$|⁠. Although the maximum number of revoked users needs to be fixed in the setup phase, the maximum number of group members is potentially unbounded as in IBR. This property has not been achieved in the recent scalable revocable group signature schemes and seems to be of independent interest.
Spatially-averaged velocity from the seafloor horizontal electric field (1990)

The theoretical relationship between the horizontal electric field (HEF) and the vertically integrated, conductivity-weighted horizontal water velocity, including the effect of finite electrical conductivity beneath the seafloor, is reviewed. This is validated by comparing data from a six-element taut current meter mooring to nearby HEF data collected in 1986-7 in the central north Pacific. The similarity of the two data sets is limited only by a high noise level in the mooring data due to rotor stalling and by large vertical wavenumber components of the velocity field that cannot be resolved with a small number of discrete velocity samples. The results of this study constitute further verification of the utility of electric field methods in oceanography.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
New iodonium salts in NIR sensitized radical photopolymerization of multifunctional monomers (2015)

Efficiency of NIR sensitized radical photopolymerization depends on the dissociation of iodonium salts comprising anions with low coordination capability.
Channel Delay Impact on CCSDS File Delivery Protocol (CFDP) over Space Communications Links (2007)

A substantially long round trip time (RTT) in space channel hurts TCP interactions between the sending and receiving ends. The consultative committee for space data systems (CCSDS) file delivery protocol (CFDP) is a new international standard developed to meet a comprehensive set of deep space file transfer requirements. There is a need in NASA to have controlled, experimental evaluation of CFDP performance in space, especially on its effectiveness in coping with long channel delay. This paper presents an experimental evaluation of channel delay impact on throughput performance of CFDP over LEO-satellite link, GEO-satellite link, and cislunar communication link in comparison with the widely deployed TCP and a space transport protocol, SCPS-TP. The experimental results show that CFDP/TCP in the deferred NAK mode is much more effective than other two stacks in the simulated point-to- point space communication links, especially when operated with a long link delay, a high BER and channel-rate asymmetry. We have found that CFDP/TCP is less sensitive, and FTP/TCP and SCPS-FP/SCPS-TP are highly sensitive, to the increase of link delay.
Analysis of CQI Prediction for MU-MIMO in LTE Systems (2012)

The aim of this paper is to get an insight of multiuser multiple-input and multiple-output (MU-MIMO) channel quality indicator (CQI) prediction for long term evolution (LTE) systems. MU-MIMO CQI predictions have been investigated for LTE Release 8 (rank one, Transmission Mode 5) and for LTE Release 9 (adaptive rank, Transmission Mode 8) at the link level. The relationship between CQI reporting and channel conditions is analytically analysed and demonstrated. The tradeoff between the performance gain and the feedback overhead w.r.t. MUMIMO CQI prediction is investigated as well. The results have shown how MU-MIMO CQI prediction is influenced by channel correlation and that significant improvements can be achieved through rank adaption and receiver choice. The results have also shown the potentially most efficient system configuration (feedback design and CQI prediction scheme) to facilitate MUMIMO transmission for practical LTE systems.
Increased Hepatic Levels of the Insulin Receptor Inhibitor, PC-1/NPP1, Induce Insulin Resistance and Glucose Intolerance (2005)

The ectoenzyme, plasma cell membrane glycoprotein-1 (PC-1), is an insulin receptor (IR) inhibitor that is elevated in cells and tissues of insulin-resistant humans. However, the effects of PC-1 overexpression on insulin action have not been studied in animal models. To produce mice with overexpression of PC-1 in liver, a key glucose regulatory organ in this species, we injected them with a PC-1 adenovirus vector that expresses human PC-1. Compared with controls, these mice had two- to threefold elevations of PC-1 content in liver but no changes in other tissues such as skeletal muscle. In liver of PC-1 animals, insulin-stimulated IR tyrosine kinase and Akt/protein kinase B activation were both decreased. In this tissue, the IR-dependent nuclear factor Foxo1 was increased along with two key gluconeogenic enzymes, glucose-6-phosphatase and phosphenolpyruvate carboxykinase. The PC-1 animals had 30-40 mg/dl higher glucose levels and twofold higher insulin levels. During glucose tolerance tests, these animals had peak glucose levels that were >100 mg/dl higher than those of controls. These in vivo data support the concept, therefore, that PC-1 plays a role in insulin resistance and suggest that animals with overexpression of human PC-1 in liver may be interesting models to investigate this pathological process.

A Case for Superconducting Accelerators (2019)

As the scaling of conventional CMOS-based technologies slows down, there is growing interest in alternative technologies that can improve performance or energy-efficiency. Superconducting circuits based on Josephson Junction (JJ) is an emerging technology that can provide devices which can be switched with pico-second latencies and consuming two orders of magnitude lower switching energy compared to CMOS. While JJ-based circuits can provide high operating frequency and energy-efficiency, this technology faces three critical challenges: limited device density and lack of area-efficient technology for memory structures, reduced gate fanout compared to CMOS, and new failure modes of Flux-Traps that occurs due to the operating environment. The lack of dense memory technology restricts the use of superconducting technology in the near term to application domains that have high compute intensity but require negligible amount of memory. In this paper, we study the use of superconducting technology to build an accelerator for SHA-256 engines commonly used in Bitcoin mining applications. We show that merely porting existing CMOS-based accelerator to superconducting technology provides 10.6X improvement in energy efficiency. Redesigning the accelerator to suit the unique constraints of superconducting technology (such as low fanout) improves the energy efficiency to 12.2X. We also investigate solutions to make the accelerator tolerant of new fault modes and show how this fault-tolerant design can be leveraged to reduce the operating current, thereby increasing the overall energy-efficiency to 46X compared to CMOS. Our paper also develops a workflow for evaluating area, performance, and power for accelerators built in superconducting technology, and this workflow can help other researchers explore designs using this technology.
New insights from the analysis of free flow vehicular traffic in highways (2011)

Building vehicular networks in roads and highways is a challenging research topic with a large number of applications ranging from traffic jams and car collisions prevention to efficient route planning. The analysis of the distance between vehicles in roads is a key factor in, e.g., designing vehicular networks protocols or planning a supporting infrastructure to improve vehicular connectivity. This work proposes a Gaussian-exponential mixture model to characterize the time distance between vehicles in a highway lane, based on measurements collected at different locations in several highways of the city of Madrid, in Spain. The model arises from the observed behavior that some vehicles travel very close together, like in a burst mode, showing Gaussian inter-arrival times, while other vehicles are somehow isolated, showing exponentially distributed inter-arrival times. The experiments show that such a Gaussian-exponential mixture model accurately characterizes inter-vehicle times observed from real traces.
Detection of Individual Vapors and Their Mixtures Using a Selectivity‐Tunable Three‐Dimensional Network of Plasmonic Nanoparticles (2013)

Sensor selectivity: Selective detection of individual vapors and their mixtures is achieved by using a single three-dimensional networked film of organothiol-functionalized plasmonic nanoparticles (see picture). This approach gives a new perspective for sensing, where tunable selectivity is achieved within a single sensing film, rather than from an array of separate conventional sensors.
