A temporary immersion system improves regeneration of in vitro irradiated recalcitrant rice embryogenic calli

The development of gamma ray-mutated rice lines is a solution for introducing variability in rice varieties already being used by farmers. In vitro gamma ray (60Co) mutagenesis reduces chimeras and allows a faster selection of desired traits but requires optimization of the laboratory procedure. The objectives of the present work were the in vitro establishment of recalcitrant rice embryogenic calli, the determination of their sensitivity to gamma radiation (60Co), sequencing of MATK and Rubisco genes for identification purposes, and optimization of the generation procedure. The radiosensitivity of the embryogenic calli showed an LD50 at 110 Gy, while the 20% lethal dose was 64 Gy. All sequenced genes matched perfectly with previously reported MATK and Rubisco O. sativa genes, with a clear SNP that identified the local variety as being related to one in the Southeast Asia region. Callus induction improved in MS medium containing 2 mg/L 2,4-D, and regeneration was achieved with MS medium with 3 mg/L BAP and 0.5 mg/L NAA. The optimized radiation condition was 60 Gy, with 83% regeneration in a semisolid medium, allowing a balance between mutation and regeneration. When the radiation increased to 80 Gy, the regeneration rate fell to 29%. An immersion system (RITA®) of either 60 or 120 seconds every 8 hours allowed systematic and homogeneous total regeneration of the recalcitrant line, in contrast with the semisolid medium that resulted in positive but irregular regeneration. Other well-known recalcitrant cultivars, CR1821 and CR1113, also had improved regeneration in the immersion system, demonstrating their potential use as recalcitrant materials. To our knowledge, this is the first report on using an immersion system to allow regeneration of gamma-ray mutants from recalcitrant rice materials.
Involvement in Renewable Energy in the Organization of the IR 4.0 Era Based on the Maturity of Socially Responsible Strategic Partnership with Customers—An Example of the Food Industry

The purpose of this study is to explain the determinants of the process of investing in renewable energy sources (RES) from the perspective of enterprises, with particular emphasis on the strength of their orientation on such strategic issues as sustainable development, orientation towards innovation, as well as the level of maturity of their partnership with the client. The research method was carried out on a sample of 157 industrial enterprises in the food industry. The research process was conducted with the consideration of making these decisions dependent on the strength of companies’ commitment to several strategic issues: sustainable development, innovation orientation, and the maturity of their partnership with the customer. The results of the data analysis collected during the quantitative research show a strong correlation between the level of openness of the organization of the IR 4.0 era to RES and (a) orientation towards sustainable development, (b) orientation towards intelligence, and (c) maturity of strategic partnering with customers.
App‐based mindfulness meditation reduces perceived stress and improves self‐regulation in working university students: A randomised controlled trial

Abstract We investigated whether a brief mindfulness meditation programme delivered via a smartphone app improves perceived stress, self‐regulation and life satisfaction in part‐time working university students. Mindfulness and cognitive reappraisal were analysed as potential mediators. A total of 64 university students working at least 20 h per week during the semester were randomised to either a mindfulness‐based mobile intervention or a wait‐list control condition. Participants in the intervention group were asked to complete one training session of 10–15 min per day using the app. Psychological measures were assessed via a self‐report questionnaire at baseline and after 8 weeks. The online mindfulness programme was found to significantly decrease perceived stress (η p 2 = .180, a large effect). It also increased self‐regulation (η p 2 = .195, a large effect), mindfulness (η p 2 = .174; a large effect) and cognitive reappraisal (η p 2 = .136, a medium effect). Increments in life satisfaction were not significant. Changes in self‐regulation were mediated by increased mindfulness. Overall, the mobile application was effective in improving mental well‐being and coping abilities in a non‐clinical sample, encouraging further development of digital health treatments.
Toward a Family Science Perspective on Executive Compensation in Family Firms: A Review and Research Agenda

In family firms, the family often plays a central role in the strategic decisions of the business. However, until recently, research has primarily focused on exploring the role that business factors play in firm decision-making, with less attention given to the role of the family system. This article reviews the research on executive compensation in family firms to understand whether and how the family system has been considered within this work. Guided by the application of family science theories, we provide a framework to explain why it is important to incorporate the family system in the future study of executive compensation in family firms. We conclude by discussing a research agenda outlining how elements of the family system can be integrated into future executive compensation research to inspire scholars to think differently about this important research topic.
Evaluation of the high-frequency small-signal performance of bipolar transistors under avalanche conditions

The S-parameters of discrete silicon bipolar microwave transistors have been measured at various collector-emitter voltages above and below the collector-emitter breakdown voltage (typically referred to as BV/sub ce0/) in order to verify the influence of avalanche multiplication on the small-signal parameters (such as f/sub t/ and f/sub max/). It was found that the small-signal device parameters are not adversely affected even when the DC characteristics deviate from the nominal behavior. The existing models for f/sub t/ and f/sub max/ are therefore valid provided that the operating point is accurately defined. >
A 1.8 V 900 $\mu$ W 4.5 GHz VCO and Prescaler in 0.18 $\mu$ m CMOS Using Charge-Recycling Technique

This letter presents a charge-recycling VCO and divider in 0.18 mum CMOS technology. The power consumption of the proposed circuit is significantly reduced by stacking the low-voltage divider on the top of the low-voltage VCO, and hence, the VCO reuses the current from the divider. To enhance the reliability of the proposed circuit under supply voltage variation, transistor sharing and adaptive body-biasing techniques are employed. It allows the proposed circuit to operate down to 1.45 V of supply voltage without degrading the FoM. Experimental results show that the proposed circuit achieves 900 muW of power consumption and -184 dBc/Hz of FoM at 1.8 V.
METHODS OF REDUCING JOINT REFLECTION CRACKING: FIELD PERFORMANCE STUDIES

Selecting rehabilitation options for Jointed Concrete Pavements (JCP’s) continues to be one of the most challenging tasks for pavement engineers. In project 0-4517, the performance of numerous treatments was investigated. Reports 0-4517-1 and 0-4517-3 identified treatments that are performing well and those that are not. Report 0-4517-2 proposed a field investigation plan for testing future candidate projects that combines visual inspections with nondestructive testing (NDT). A sequenced approach is proposed for NDT evaluation that includes Ground Penetrating Radar (GPR) and deflection testing and in some instances Dynamic Cone Penetrometer (DCP) testing. Deflections can be taken with either the Falling Weight Deflectometer (FWD) or Rolling Dynamic Deflectometer (RDD). Three treatments were found to be performing well. For JCPs without major failures, the use of an asphalt overlay should be considered. Good agreement was found between field reflection cracking performance and the results from laboratory testing with Texas Transportation Institute's (TTI’s) overlay tester. Future overlay of JCPs should follow the overlay tester criteria proposed in this report. For sections with moderate levels of deterioration, with adequate support and no trapped moisture the use of rubblization is a good alternative. The rubblized concrete was found to provide a more uniform support than Crack and Seat. For those sections that are not candidates for rubblization because of poor slab support, then a flexible base overlay appears to be a good alternative. The flexible base overlays on US 59 in Lufkin and US 83 in Childress are performing very well.
BI-2536 Promotes Neuroblastoma Cell Death via Minichromosome Maintenance Complex Components 2 and 10

DNA replication is initiated with the recognition of the starting point of multiple replication forks by the origin recognition complex and activation of the minichromosome maintenance complex 10 (MCM10). Subsequently, DNA helicase, consisting of the MCM protein subunits MCM2-7, unwinds double-stranded DNA and DNA synthesis begins. In previous studies, replication factors have been used as clinical targets in cancer therapy. The results showed that MCM2 could be a proliferation marker for numerous types of malignant cancer. We analyzed samples obtained from patients with neuroblastoma, revealing that higher levels of MCM2 and MCM10 mRNA were associated with poor survival rate. Furthermore, we combined the results of the perturbation-induced reversal effects on the expression levels of MCM2 and MCM10 and the sensitivity correlation between perturbations and MCM2 and MCM10 from the Cancer Therapeutics Response Portal database. Small molecule BI-2536, a polo-like kinase 1 (PLK-1) inhibitor, is a candidate for the inhibition of MCM2 and MCM10 expression. To test this hypothesis, we treated neuroblastoma cells with BI-2536. The results showed that the drug decreased cell viability and reduced the expression levels of MCM2 and MCM10. Functional analysis further revealed enrichments of gene sets involved in mitochondria, cell cycle, and DNA replication for BI-2536-perturbed transcriptome. We used cellular assays to demonstrate that BI-2536 promoted mitochondria fusion, G2/M arrest, and apoptosis. In summary, our findings provide a new strategy for neuroblastoma therapy with BI-2536.

Development of Korean-to-English and English-to-Korean Mobile Translator for Smartphone

In this paper we present light weighted English-to-Korean and Korean-to-English mobile translators on smart phones. For natural translation and higher translation quality, translation engines are hybridized with Translation Memory (TM) and Rule-based translation engine. In order to maximize the usability of the system, we combined an Optical Character Recognition (OCR) engine and Text-to-Speech (TTS) engine as a Front-End and Back-end of the mobile translators. With the BLEU and NIST evaluation metrics, the experimental results show our E-K and K-E mobile translation equality reach 72.4% and 77.7% of Google translators, respectively. This shows the quality of our mobile translators almost reaches the that of server-based machine translation to show its commercial usefulness.
Association of Serum Triglycerides in Patients with Ischaemic Stroke Admitted in Hospital with type-2 Diabetes Patients

Background and Aims: Diabetes mellitus and dyslipidemia, in particular triglyceridemia pose independent risk factors of stroke. Hypertriglyceridemia implicated in the pathogenesis of ischemic stroke by imparting endothelial dysfunction, oxidative stress and lowering fibrinolytic activity. This study was aimed to explore risk incurred by blood triglyceride level for ischemic stroke in type 2 diabetic patients. Materials and Methods: A total number of 80 [50 with acute ischemic stroke and 30 without stroke] type 2 diabetic patients consecutively admitted in the neurology department, during the period of April to September 2012, fulfilling the recruitment criteria were included in the study. Ischemic stroke was confirmed by CT-scan. Informed written consent from the legal attendant of each patient was obtained. Data regarding clinicobiochemical and images studies were retrieved from patient’s record form. Results: Male to female ratio was 1.2:1 of the study subjects. Mean (±SD) age (yrs) was 61.0±10.6 in patients with ischemic stroke (Group I) and 57.0±12.3 in patients without stroke (Group II). Risk factors like BMI, lifestyle, smoking, alcohol intake did not show any statistical significance with incidence of ischemic stroke. Mean (±SD) triglyceride (mg/ dl) was 241±56 and 217±102 in Group I and Group II respectively (p=0.024). Eighty eight percent patients had triglyceride 150 mg/dl in Group I and 70 percent in Group II. Triglyceride level (mean±SD, mg/dl) was significantly higher (335±101) in overweightobese patients (BMI 25 Kg/m2) compared to those (232±68) with normal body weight (BMI<25 Kg/m2). Triglyceride level did not show statistical difference among patients having habit of smoking or not. Mean (±SD) cholesterol (mg/dl, (±SD) was 197±62 and 165±26 in Group I and Group II respectively (p=0.009). Mean (±SD) LDL-c (mg/dl) was 101±45 and 98±42 in Group I (43.8±34.4) compared to Group II (60.2±15.6) (p=0.017). Patients with atherosclerotic changes had significantly higher triglyceride (mean±SD, mg/dl) level (338±155) compared to those without (228±89) (p=0.047). Conclusions: Data concluded that hypertriglyceridemia is relatively common among the diabetic patients even in patients with apparently good glycemic control and possibly incur added risk for ischemic stroke in these patients. However, further studies are needed involving optimum number of patients to substantiate this finding and conclusively comment on the issue and to design effective prevention program to reduce the cerebrovascular morbidity and mortality.

A Noise Control Method Using Adaptive Adjustable Parametric Array Loudspeaker to Eliminate Environmental Noise in Real Time

Long-term exposure to environmental noise is dangerous to human health. Therefore, there is an urgent need to suppress or eliminate environmental noise. Due to the limitation of environmental space, the use of reverse sound waves emitted by loudspeakers for noise elimination has been widely used in noise control. However, because of the omni-directionality of sound propagation, a traditional voice coil loudspeaker (VCL) is used as a secondary source (emission reverse sound wave). It is easy to increase the sound pressure in non-target areas and form significant acoustic feedback to the reference source. Therefore, we propose an online secondary path modeling method using an adjustable parametric array loudspeaker (PAL) based on ultrasounds to eliminate environmental noise in real time. According to the different distance of the target, the size of the PAL is adjusted adaptively to realize the noise control of different long-distance targets. The distribution of quiet areas is discussed. The experimental results showed that a PAL as a secondary source had the same noise reduction effect as a traditional VCL, but it had longer propagation distance, smaller sound feedback and a more regular and controllable distribution of quiet areas. These research findings have great potential for improving environmental noise and creating a quiet environment.
Low-voltage CMOS frequency synthesizer for ERMES pager application

A low-voltage frequency synthesizer fabricated with a 0.35-/spl mu/m standard CMOS technology is presented. A 1 V dual-modulus prescaler using the dynamic back-gate forward bias method has been developed for low-voltage operation. The prescaler, including a preamplifier, measured at 1 V supply voltage has a maximum operating frequency of 170 MHz, and its power dissipation is only 0.9 mW. The voltage-controlled oscillator (VCO) in the frequency synthesizer is an LC-tank based oscillator. When locked at the oscillation frequency of 148 MHz, the measured phase noise of the VCO is -106 dBc/Hz at -100-kHz from the carrier. The whole power consumption of the frequency synthesizer is 10.5 mW.
Intrusion Detection System-Based Security Mechanism for Vehicular Ad-Hoc Networks for Industrial IoT

Security is an absolutely crucial aspect of any Industrial Internet of Things (IIoT) network that must be considered carefully to protect users while allowing for proper, error-free functioning of the entire network. Vehicular ad-hoc networks (VANETs) are a type of network that has emerged with the aim of strengthening the available intelligent transportation systems. Enhancing overall security in VANETs should be a top priority as problems in these networks can put lives at risk. Various security frameworks and solutions including the use of intrusion detection systems (IDS) have been proposed in the literature by researchers across the globe. In this study, the various challenges and problems associated with IDS usage in VANETs are thoroughly examined. In order to enhance the detection capabilities of IDS such that they can detect both existing and zero-day unknown attacks, we present a novel approach that makes use of honeypots in addition to conventional IDS to improve VANET security. We believe our honeypot-based IDS solution for VANETs will prove itself by enhancing overall detection rates while consuming fewer resources. Various design considerations like the optimal number of honeypot nodes, deployment locations of those nodes, type of IDS to be used, etc., are discussed herein. The main objective behind this study is to explore the various types of IDS already being used in VANETs for intrusion detection as well as to understand the challenges and benefits each approach offers, we hope that this work will become a valuable resource for researchers working in this field in the future.
Noise reduction for switched reluctance motor with a hole

A switched reluctance motor has a doubly salient structure, both stator and rotor have the saliency and it has an advantage in a harsh environments due to a simple and robust structure. However, it has the disadvantage that the motor is noisy because of the deformation by the radial force. This paper examines the radial force for various SRMs with a hole inside the pole using the two dimensional finite element method, and for typical models, the acoustic noise and efficiency are evaluated by the experiments. It is cleared that poles with a hole are effective to improve the noise, because the radial force reduces.
Pulsed High‐Peak Power Microwaves at 9.4 GHz Do Not Affect Basic Endpoints in Caenorhabditis elegans

Because of the extensive application of electromagnetic technology, its health impact on humans has attracted widespread attention. Due to the lack of a model organism with a stable response to electromagnetic waves, the research conclusions on the biological effects of electromagnetic waves have been vague. Therefore, the aim of this study was to investigate the effects of irradiation by pulsed 9.4 GHz high‐power microwaves with a peak power density of 2126 W/cm2 using Caenorhabditis elegans. The development, movement, egg production, ROS, and lifespan of C. elegans were detected at different times after irradiation with different repetitive frequencies of 10, 20, and 50 Hz for 30 min. The results indicated that no obvious changes in basic life indices were induced compared with the sham radiation group, but the survival rate of positive control was significantly decreased compared with other groups, which is of interest for microwave protection research based on C. elegans and provides data for updating safety standards with respect to pulsed high‐peak power microwave. © 2021 Bioelectromagnetics Society.
High-frequency DC/DC converter for lithium-ion battery applications utilizes ultra-fast CBiC/D process technology

Implementation of a 1-MHz switchmode control IC for DC-to-DC conversion in single-cell lithium ion (3- to 4.2-V) applications using an ultra-fast CBiC/D technology is demonstrated. The combination of low-threshold CMOS and high-speed bipolars (3 GHz NPN, 800 MHz PNP) is used to realize a high-speed comparator, 25-MHz error amplifier, and low propagation output delay output buffer at low operating currents. A low-profile, small footprint synchronous Buck converter with excellent ripple and transients response illustrates the benefits of operation at high clock rates. <<ETX>>
New anode design concept of 600V thin wafer PT-IGBT with very low dose p-buffer and transparent p-emitter

We propose 600V new thin wafer PT (Punch Through) IGBT having a new concept of anode design. This proposed PT-IGBT has a very low dose p-type layer, called p-buffer, between a transparent p-emitter (anode) and an n-buffer layer. This provides a practical design for easy fabrication without deteriorating the good feature of the thin wafer PT-IGBTs. The n-buffer dose and the p-emitter dose can be precisely controlled by the doses of the two ion implantations. This is great merit in precise control of the p-emitter injection efficiency. An oscillation in the turn-off waveforms also disappears for the proposed PT-IGBT with p-buffer layer, because a smooth turn-off is achieved by a small tail current. The total power loss is not affected by the small tail loss.
Bi-directional DC to DC converters for fuel cell systems

This paper first describes the need of a bi-directional DC to DC converter for a fuel cell system. Various combinations of current-fed and voltage-fed converters are explored for the application of different voltage levels. With a preliminary study, putting current-fed on low-voltage side and voltage fed on high voltage side indicated higher efficiency than the other way around. Two low-side circuit topologies were then selected for hardware implementation. One is the L-type half-bridge current-fed converter, and the other is full-bridge current-fed converter. The high-side circuit topology is fixed with a full-bridge voltage-fed converter. Two systems were built and tested to full power. The results indicate that the combination with the full-bridge converter on the low-voltage side is more efficient than the combination with the L-type half-bridge converter on the low-voltage side for both charging and discharging modes.
