Unravelling the Photoprotection Properties of Garden Cress Sprout Extract

Plants, as with humans, require photoprotection against the potentially damaging effects of overexposure to ultraviolet (UV) radiation. Previously, sinapoyl malate (SM) was identified as the photoprotective agent in thale cress. Here, we seek to identify the photoprotective agent in a similar plant, garden cress, which is currently used in the skincare product Detoxophane nc. To achieve this, we explore the photodynamics of both the garden cress sprout extract and Detoxophane nc with femtosecond transient electronic absorption spectroscopy. With the assistance of liquid chromatography-mass spectrometry, we determine that the main UV-absorbing compound in garden cress sprout extract is SM. Importantly, our studies reveal that the photoprotection properties of the SM in the garden cress sprout extract present in Detoxophane nc are not compromised by the formulation environment. The result suggests that Detoxophane nc containing the garden cress sprout extract may offer additional photoprotection to the end user in the form of a UV filter booster.
A DC method for measuring all the gate capacitors in MOS devices with atto-farad resolution

In this paper we present a new methodology for measuring all the intrinsic gate capacitors (i.e., gate-source, gate-drain, and gate-bulk) in a MOS device using a DC measurement scheme. The structure consists of two matched MOSFET's, one of which has a reference capacitor attached to its gate. The test structure was fabricated and the results show a resolution in the atto-farads range. The test structures use charge coupling to measure the gate capacitors.
Targeted proteomics for evaluating risk of venous thrombosis following traumatic lower‐leg injury or knee arthroscopy

Patients with lower‐leg cast immobilization and patients undergoing knee arthroscopy have an increased risk of venous thrombosis (VT). Guidelines are ambiguous about thromboprophylaxis use, and individual risk factors for developing VT are often ignored. To assist in VT risk stratification and guide thromboprophylaxis use, various prediction models have been developed. These models depend largely on clinical factors and provide reasonably good C‐statistics of around 70%. We explored using protein levels in blood plasma measured by multiplexed quantitative targeted proteomics to predict VT. Our aim was to assess whether a VT risk prediction model based on absolute plasma protein quantification is possible.
Flexible dot-matrix display manufacture by offset lithography

Novel thermochromic graphic displays manufactured by printing thermochromic ink films in conjunction with conductive lithographic films (CLFs) are presented. Work in formulating lithographic printing inks is described. The properties of the deposited ink films and demonstration display structures employing these materials are discussed. These low-cost printed structures could be incorporated in the manufacture of electronic systems with integrated printed power sources affording environmental benefits when compared with conventional manufacturing techniques.
Piezo films with adjustable anisotropic strain for bending actuators with tunable bending profiles

We present a method to produce in-plane polarized piezo films with a freely adjustable ratio of the strains in orthogonal in-plane directions. They can be used in piezo bending actuators with a tunable curvature profile. The strains are obtained as mean strains from a periodic polarization pattern produced by a suitable doubly interdigitated electrode structure. This mechanism is demonstrated for several examples using PZT sheets. We further discuss how this tuning and the parameters of the electrode layout affect the overall magnitude of the displacement.
Role of HSV-1 Capsid Vertex-Specific Component (CVSC) and Viral Terminal DNA in Capsid Docking at the Nuclear Pore

Penetration of the viral genome into a host cell nucleus is critical for initiation of viral replication for most DNA viruses and a few RNA viruses. For herpesviruses, viral DNA ejection into a nucleus occurs when the capsid docks at the nuclear pore complex (NPC) basket with the correct orientation of the unique capsid portal vertex. It has been shown that capsid vertex-specific component (CVSC) proteins, which are located at the twelve vertices of the human herpes simplex virus type 1 (HSV-1) capsid, interact with nucleoporins (Nups) of NPCs. However, it remained unclear whether CVSC proteins determine capsid-to-NPC binding. Furthermore, it has been speculated that terminal DNA adjacent to the portal complex of DNA-filled C-capsids forms a structural motif with the portal cap (which retains DNA in the capsid), which mediates capsid-NPC binding. We demonstrate that terminal viral DNA adjacent to the portal proteins does not present a structural element required for capsid-NPC binding. Our data also show that level of CVSC proteins on the HSV-1 capsid affects level of NPC binding. To elucidate the capsid-binding process, we use an isolated, reconstituted cell nucleus system that recapitulates capsid-nucleus binding in vivo without interference from trafficking kinetics of capsids moving toward the nucleus. This allows binding of non-infectious capsid maturation intermediates with varying levels of vertex-specific components. This experimental system provides a platform for investigating virus–host interaction at the nuclear membrane.
Temperature-modulated direct thermoelectric gas sensors: thermal modeling and results for fast hydrocarbon sensors

Direct thermoelectric gas sensors are a promising alternative to conductometric gas sensors. For accurate results, a temperature modulation technique in combination with a regression analysis is advantageous. However, the thermal time constant of screen-printed sensors is quite large. As a result, up to now the temperature modulation frequency (20 mHz) has been too low and the corresponding principle-related response time (50 s) has been too high for many applications. With a special design, respecting the physical properties of thermal waves and the use of signal processing similar to a lock-in-amplifier, it is possible to achieve response times of about 1 s. As a result, direct thermoelectric gas sensors with SnO2 as a gas-sensitive material respond fast and are reproducible to the propane concentration in the ambient atmosphere. Due to the path-independent behavior of the thermovoltage and the temperature, the measured thermopower of two sensors is almost identical.
The Effects of Person–Organization Fit and Turnover Intention on Employees’ Creative Behavior: The Mediating Role of Psychological Ownership

Some recent studies have examined the behavioral antecedents of employees’ creative behavior. However, the potential role of psychological ownership is rarely taken into consideration. This study specifically examines the mediating role of psychological ownership in the relationship between person–organization (P–O) fit and turnover intention on the one hand and employees’ creative behavior on the other via a survey in Turkish organizations. Findings based on the data from 969 employees in Istanbul and Western Anatolia indicate that P–O fit is positively related and turnover intention negatively related to both psychological ownership and creative behavior, and that psychological ownership plays a full mediating role in these relations. Psychological ownership has a central role in employees’ creative behavior; it should thus be augmented together with its antecedents if managers wish to foster creative behaviors among their employees.
Attachment loss of micromechanical and nanomechanical resonators in the limits of thick and thin support structures

Analytical expressions are provided for the energy loss from vibrating mechanical resonators into their support structures for two limiting cases: supports that can be treated as plates, and supports that act as semi-infinite elastic media, with effectively infinite thickness. The former case is applicable to many microscale resonators, while the latter is appropriate for nanoscale devices. General formulations are given, applicable to a wide range of resonator geometries. These formulations are then applied to two geometries commonly used in microelectromechanical systems and nanelectromechanical systems applications: cantilevered beams and doubly fixed beams. Experimental data are presented to validate the finite-thickness support theory, and the predictions of the theory are also compared to data from existing literature for a microscale rectangular paddle oscillator.
Assessing spontaneous howling rates in captive wolves using automatic passive recorders

ABSTRACT We studied the spontaneous vocal behaviour of captive wolves at the International Wolf Center (IWC) in Minnesota (spring 2019 and winter 2020), and the Centro del Lobo Ibérico Félix Rodríguez de la Fuente (CLIFRF) in Spain (winter 2020). We used AudioMoth recording devices to record wolf howling 24 h/day. We identified 412 solo howl series and 403 chorus howls and found differences between wolves at the two centres. Vocal rates for North American wolves at the IWC (7.8 chorus howls/day in spring and 4.8 chorus howls/day in winter) were higher than rates obtained for Iberian wolves from CLIFRF (3.8 chorus howls/day in winter). Howling rates obtained in our study were similar to those obtained for captive Mexican wolves and greater than those reported for wild wolves. Hourly distribution of howling was also different between centres. The greatest howling activity identified at IWC was at pre-sunrise, while at CLIFRF the peak occurred at sunset. Weather conditions had little influence on the vocal behaviour of the captive wolves we studied. We show the potential of passive recorders to study topics of animal acoustic communication, such as vocal rates and temporal patterns, that have not been deeply addressed due to technological constraints.
Evaluation of an EDLC-battery hybrid stand-alone photovoltaic power system

We have proposed a stand-alone photovoltaic power system that uses electric double-layer capacitors (EDLCs) and lead acid batteries as power storage devices. We simulated the system's operating characteristics and evaluated the photovoltaic array mismatching loss, system conversion loss, battery contribution factor, averaged battery state-of-charge, and maximum depth-of-discharge. The results show that the system is effective at reducing the mismatching loss and battery contribution factor, so the system efficiency is improved. Moreover the system can maintain the averaged battery state-of-charge during operation. The maximum depth-of-discharge can be kept higher than in the conventional system. Consequently, the proposed system should have a longer battery lifetime.
Aggregation and amplification of wind-turbine harmonic emission in a wind park

Summary form only given. This paper presents measurements of harmonic and interharmonic current (with 5 Hz frequency resolution) in the complex plane. The complex currents are spread around a center point. For interharmonics this center corresponds with the origin of the complex plane. For integer harmonics this center is off-set from the origin. A goodness-of-fit test reveals that phase angles of most interharmonics are uniformly distributed. A Monte-Carlo simulation based on the measurements has been performed to study the aggregation of the emission from individual turbines to the public grid. Low-order integer harmonics show less cancellation compared to high-order harmonics. Interharmonics aggregate close to the square-root rule for uniform phase angles.
Model Predictive Torque Control for PMSM Drives Based on Weighting Factor Elimination and Enhancement of Inductance Parameter Robustness

This paper proposes a improved model predictive torque control for permanent magnet synchronous motor based on elimination of weighting factor. For flux and torque, deadbeat control is used, and the reference voltage vector can be solved, eight voltage vectors are transformed into two alternative voltage vectors through the position angle of reference voltage vector, among the alternative vectors, the one with the minimum error from reference voltage vector is optimal voltage vector, thus, the design of weighting factor is avoided, and reduces the computational burden. Additionally, model reference adaptive system is used to identify actual inductance parameter online and update it in real time to enhance the robustness of inductance parameter. Finally, simulation results demonstrate the validity of the proposed algorithm.
Water content monitoring for nuclear concrete buildings: needs, feedback and perspectives

The paper presents an overview of the different attempts undertaken by EDF from the 1980’ to now to monitor the water content throughout time in the concrete structures of nuclear power plants. A brief review of existing techniques is proposed, associated to a focus on those chosen by EDF to be tested on site. A feedback on capacitive probes embedded in concrete is provided. An example of metrological requirement for this kind of sensor is presented, in relation with their use in structural analysis. Future research works and considered perspectives are discussed.
STABILITY ANALYSIS AND VIBRATION CONTROL OF A CLASS OF NEGATIVE IMAGINARY SYSTEMS

This paper presents stability analysis and vibration control of a class of negative imaginary systems. A flexible manipulator that moves in a horizontal plane is considered and is modelled using the finite element method. The system with two poles at the origin is shown to possess negative imaginary properties. Subsequently, an integral resonant controller (IRC) which is a strictly negative imaginary controller is designed for the position and vibration control of the system. Using the IRC, the closed-loop system is observed to be internally stable and simuation results show that satisfactory hub angle response is achieved. Furthermore, vibration magnitudes at the resonance modes are suppressed by 48 dB.
Cockpit Checklists: Concepts, Design, and Use

Although the aircraft checklist has long been regarded as a foundation of pilot standardization and cockpit safety, it has escaped the scrutiny of the human factors profession. The improper use, or nonuse, of the normal checklist by flight crews is often cited as a major contributing factor to aircraft accidents. This paper reports the results of a field study of flight deck checklists and examines this seemingly mundane yet critical device from several perspectives: its functions, format, design, length, and usage, and the limitations of the humans who must interact with it. Certain sociotechnical factors, such as the airline "culture," cockpit resource management, and production pressures that influence the design and use of this device, are also discussed. Finally, a list of design guidelines for normal checklists is provided. Although the focus of this paper is on the air transport industry, most of the principles discussed apply equally well to other high-risk industries, such as maritime transportation, power production, weapons systems, space flight, and medical care.
Composite Quantile Probability Predictions: Performance and Coherence Analysis of US COVID-19 Confirmed Infection Cases

An analytical framework is presented for the evaluation of composite probability forecasts using empirical quantiles. The framework is demonstrated via the examination of forecasts of the changes in the number of US COVID-19 confirmed infection cases, applying 18 two-week ahead quantile forecasts from four forecasting organisations. The forecasts are analysed individually for each organisation and in combinations of organisational forecasts to ascertain the highest level of performance. It is shown that the relative error reduction achieved by combining forecasts depends on the extent to which the component forecasts contain independent information. The implications of the study are discussed, suggestions are offered for future research and potential limitations are considered.
THE ROLE OF TQM AND ORGANIZATIONAL CULTURE ON OPERATIONAL PERFORMANCE

TQM is one of the essential factors in organizational activities. This research aims to determine how TQM elements and organizational culture can lead to operational performance in a mineral water manufacturer in Pasuruan, East Java, Indonesia. Aside from that, researchers also measure how TQM elements, organizational culture, and operational performance can affect corporate performance. The respondents are 50 people from staff, suppliers, and consumers of the manufacturer. The method used in this research is a quantitative method that uses path analysis. The results showed that there is a significant impact between soft TQM elements towards operational performance. The results also showed a significant effect between hard TQM elements, organizational culture, and operational performance towards corporate performance. This research differs from other studies because the model analysis correlates organizational culture with TQM elements in a mineral water company.
Bidirectional DC-DC converter fed drive for electric vehicle system

Batteries are the primary energy-storage devices in ground vehicles. Now days battery fed electric drives are commonly being used for electric vehicles applications, due to various advantages, such as: nearly zero emission, guaranteed load leveling, good transient operation and energy recovery during braking operation. To fulfill these requirements converters with bidirectional power flow capabilities are required to connect the accumulator (battery) to the dc link of the motor drive system. Battery fed electric vehicles (BFEVs) is required to function in three different modes namely: acceleration mode, normal (steady-state) mode and braking (regenerative) mode. During acceleration and normal modes the power flow is from battery to motor where as during braking or regenerative mode the kinetic energy of the motor is converted into electrical energy and fed back to battery. The DC-DC converter is required to perform mainly two functions: first to match the battery voltage to the motor rated voltage and second to control the power flow under steady-state and transient conditions, so that the drive performance is as per the requirement. In the present work closed loop operation of bi-directional dc-dc converter feeding a dc motor and its energy recovery due to regenerative braking has been demonstrated. The characteristics of battery operated electric vehicle under different drive condition are also presented. The effectiveness of the system is verified through the simulations using Simulink/ MATLAB 7.6. 0 (R2008a) package.
A Critical Assessment on Functional Attributes and Degradation Mechanism of Membrane Electrode Assembly Components in Direct Methanol Fuel Cells

Direct methanol fuel cells (DMFC) are typically a subset of polymer electrolyte membrane fuel cells (PEMFC) that possess benefits such as fuel flexibility, reduction in plant balance, and benign operation. Due to their benefits, DMFCs could play a substantial role in the future, specifically in replacing Li-ion batteries for portable and military applications. However, the critical concern with DMFCs is the degradation and inadequate reliability that affect the overall value chain and can potentially impede the commercialization of DMFCs. As a consequence, a reliability assessment can provide more insight into a DMFC component’s attributes. The membrane electrode assembly (MEA) is the integral component of the DMFC stack. A comprehensive understanding of its functional attributes and degradation mechanism plays a significant role in its commercialization. The methanol crossover through the membrane, carbon monoxide poisoning, high anode polarization by methanol oxidation, and operating parameters such as temperature, humidity, and others are significant contributions to MEA degradation. In addition, inadequate reliability of the MEA impacts the failure mechanism of DMFC, resulting in poor efficiency. Consequently, this paper provides a comprehensive assessment of several factors leading to the MEA degradation mechanism in order to develop a holistic understanding.
High-efficiency module-integrated photovoltaic power conditioning system

A module-integrated, photovoltaic (PV) power conditioning system with a high-efficiency, high step-up DC-DC converter is proposed. The step-up DC-DC converter employs an active-clamp circuit for soft switching of the power semiconductor switches. Also, a dual series-resonant rectifier is employed in order to remove the reverse-recovery problem of the output-rectifying diodes and to provide a much higher voltage conversion ratio. The PV current is estimated without using a DC current sensor, and the PV current ripple reduction technique is suggested to reduce the current ripple without an external component. A 1 kW prototype for the PV voltage range of 30-60 V is implemented, and all algorithms and controllers are implemented on a single-chip microcontroller. Experimental results show that the power efficiency is 92.5-94% and the ripple current is 3.5% of the rated input current.
Design of MEMS Wireless Air-Mouse System Based on MEMS Technology

In this paper, we study the MEMS wireless air-mouse system(MWAMS), which based on three-axis gyroscope、three-axis accelerometer、magnetometer and wireless RF technology. It makes use of MEMS motion sensing technology、information fusion algorithm and DCM complementary filter algorithm to sensing air-mouse's motion. This paper presents a new multi-sensor optimal information fusion and mapping algorithm. Compared to the traditional algorithm, this new algorithm based on MEMS technology not only has higher performance-higher location accuracy and better smoothness, but also has lower power consumption.
The development of non-uniform deposition of holes in gate oxides

The subthreshold technique was used to study irradiated MOS transistors at 80 K. Stretchout of the subthreshold curve demonstrated production of lateral nonuniformities (LNUs) in the hole distribution. The LNUs were analyzed in terms of a parallel transistor model and the statistics of the nonuniform distribution of dose deposition in the SiO/sub 2/. The results confirm the hypothesis that at 80 K the principal source of LNUs is the granularity in dose deposition. The relative standard deviation for the deposited dose is large for thin oxides, for 10 keV X-rays (as opposed to Co-60), and at low doses. These physical phenomena are predicted to have a significant effect at room temperature. >
Cardiovascular comorbidities in psoriasis (Review)

Long considered a skin-limited condition, psoriasis is currently defined as a chronic, immune-mediated inflammatory disease, presenting, besides the skin changes, important systemic manifestations, the most common being: psoriatic arthritis, cardiovascular disease, metabolic syndrome, diabetes, inflammatory bowel disease and nonalcoholic steatohepatitis. It is a disease with a strong psycho-emotional and social impact, both through skin changes such as pruritic, scaly erythematous plaques, and through the association of comorbidities that influence morbidity and mortality. It has been shown that psoriasis is an independent cardiovascular risk factor, with patients developing ischemic heart disease/acute coronary syndrome, hypertension, peripheral arterial disease, or stroke. The chronic inflammatory status of psoriasis and the production of specific cytokines may be the etiopathogenic link to atherosclerosis and cardiovascular disease. Biological therapy may affect atherosclerosis, leading to the arrest of the evolution or even regressing the changes in the atheromatous plaque. The aim of this review was to re-evaluate the current knowledge regarding the cardiovascular comorbidities associated with psoriasis for optimal management of the patients.
