Pinching the cortex of live cells reveals thickness instabilities caused by myosin II motors

Magnetic beads are used as a caliper to measure the cortical layer of dendritic cells and its temporal variations. The cell cortex is a contractile actin meshwork, which determines cell shape and is essential for cell mechanics, migration, and division. Because its thickness is below optical resolution, there is a tendency to consider the cortex as a thin uniform two-dimensional layer. Using two mutually attracted magnetic beads, one inside the cell and the other in the extracellular medium, we pinch the cortex of dendritic cells and provide an accurate and time-resolved measure of its thickness. Our observations draw a new picture of the cell cortex as a highly dynamic layer, harboring large fluctuations in its third dimension because of actomyosin contractility. We propose that the cortex dynamics might be responsible for the fast shape-changing capacity of highly contractile cells that use amoeboid-like migration.
Effect of Different Light Qualities on Physiological Characteristics and Growth of Tobacco in vitro under Light Emitting Diodes(LEDs)

By arraying tobacco rooted plantlets with the different wave length and ratio of light emitting diodes(LEDs),with fluorescent lamp(CK)light as control,the effects of light quality on physiological characteristics and growth were investigated.The results showed that:(1)Red-blue-green(RBG)and Red-bluewhite(RBW)light enhanced the heights,leaf lengths and leaf widths,leaf area,shoot diameter,root length,number of root and dry weigh of plant,and the contents of chlorophyll were also up-graduated,but those of treatments were no significantly differences. (2)RBW light treatments led to higher content of soluble sugar and C/N ratio,RBG light treatments led to higher content of free amino acid,and significantly higherthan that of other treatments;for all light treatments,tobacco leaf soluble protein content is significantly higher than that of CK light treatment,1Red-blue(1RB)light treatment led to higher content of soluble starch,and significantly higher than that of CK light treatment. (3)Fluorescent lamp(CK)light treatments led to higher contents of MDA,and significantly higher than that of other treatments;while decreased activities of SOD,CAT and POD in the leave,and significantly lower than those of other treatments;which red light lowered content of MDA and enhanced activity of POD,and CAT activity is the highest.LED light source can significantly reduce the MDA content of tobacco plantlets,reduce the membrane lipid peroxidation damage,promote the growth of tobacco plantlets,and the main reason lies in its regulation metabolism of the activities of antioxidant enzymes in response to photo-oxidative stress.
Bringing deterministic industrial networking to the W3C web of things with TSN and OPC UA

IoT is often associated with low-power wireless, where best-effort communication is sufficient for many of its applications. Yet, in particular in Industrial IoT, strict quality of service (QoS) guarantees are required to enable deterministic real-time applications. Hence, wired communications are still predominant here, with Ethernet having become the main media for the industrial fieldbuses such as PROFINET, EtherCAT, or the emerging Field-Level Communications (FLC) of OPC UA. With the addition of Time-Sensitive Networking (TSN), an IEEE standards family for deterministic networking over Ethernet, Information Technology (IT) and Operational Technology (OT) can converge even at the shopfloor, as TSN-enabled Ethernet allows for several traffic types to co-exist in the same network. This paper proposes an extension to the W3C Web of Things (WoT) for semantics-enabled connectivity, which allows to cover application QoS requirements and network configuration within the W3C WoT abstractions. We contribute a QoS vocabulary for the W3C WoT Thing Description as well as design and open-source implementation of protocol bindings for OPC UA and NETCONF. Moreover, we discuss the challenges and pitfalls when designing new protocol bindings for W3C WoT.
Application of Affine-based Reconstruction to Retinal Point Patterns

Inverse biometrics that exploit the information of biometric references from comparison scores can compromise sensitive personal information of the users in biometric recognition systems. One inverse biometric method that has been very successful in regenerating face images applies an affine transformation to model the face recognition algorithm. This method is general and could apply to templates extracted from other biometric characteristics. This research proposes two formats to apply this method to spatial point patterns extracted from retina images and tests its performance on reconstructing such sparse templates. The results show that the quality of the reconstructed retina point pattern templates is lower than would be accepted by the system as mated.
UAV-Based Photogrammetry and LiDAR for the Characterization of Ice Morphology Evolution

Ice doline is a particular kind of ice morphology, usually scattered on ice streams which are mostly far from the existing research bases. For this reason, glaciologists rarely have opportunities to document its developments in detail. Satellite observations are too coarse to capture such fine features, whereas unmanned aerial vehicle (UAV)-based structure-from-motion (SfM) and light detection and ranging (LiDAR) technologies have revolutionized geosciences research, especially in less accessed polar regions. We developed two bespoke UAV systems for glaciological investigation and carried out four campaigns during two consecutive Chinese Antarctic expeditions in 2017 and 2018. Founded on manual co-registration and accuracy assessment, a successful application to characterize a doline's spatio-temporal evolution is presented in this article. The overlying weight of surface melting directly triggered the collapse event on Jan 30, 2017 near the Dalk Glacier, and thenthe newborn doline grew for another 8135.6 m$^2$ in area and 280 303.38 m$^3$ in volume by early 2018. The UAV-based results revealed the doline's changes during a year, showing a maximum horizontal extension of 50 m and vertical subsidence of more than 10 m. Furthermore, we evaluate the photogrammetry and LiDAR systems and find the former is cost-effective and time-efficient on a large-scale survey, while the latter enjoys a better capability to characterize ice morphological details. Based on systematic comparisons, other pros and cons of the two techniques are discussed. To achieve the best performance for relevant applications in similar scenarios, we recommend adopting an integrated approach, in which the LiDAR restores the fine features on the basis of extensive SfM coverage.
Touchless Fingerprint Sample Quality: Prerequisites for the Applicability of NFIQ2.0

The impact of fingerprint sample quality on biometric performance is undisputed. For touch-based fingerprint data, the effectiveness of the NFIQ2.0 quality estimation method is well documented in scientific literature. Due to the increasing use of touchless fingerprint recognition systems a thorough investigation of the usefulness of the NFIQ2.0 for touchless fingerprint data is of interest.In this work, we investigate whether NFIQ2.0 quality scores are predictive of error rates associated with the biometric performance of touchless fingerprint recognition. For this purpose, we propose a touchless fingerprint preprocessing that favours NFIQ2.0 quality estimation which has been designed for touch- based fingerprint data. Comparisons are made between NFIQ2.0 score distributions obtained from touch-based and touchless fingerprint data of the publicly available FVC06, MCYT, PolyU, and ISPFDv1 databases. Further, the predictive power regarding biometric performance is evaluated in terms of Error-versus- Reject Curves (ERCs) using an open source fingerprint recognition system. Under constrained capture conditions NFIQ2.0 is found to be an effective tool for touchless fingerprint quality estimation if an adequate preprocessing is applied.
Relationship between resistance against alginic-acid-decomposing bacteria and antioxidative activity in Laminaria japonica

Using biochemistry methods, two strains of seaweed Laminaria japonica were analyzed. The strains named L. japonica No.1 and L. japonica 901 (briefly No.1 and No.901), respectively, with body length 1.2 1.5 m . The results show that the resistance against alginic acid decomposing bacteria in No.1 is much higher than that in No.901, and the activity of superoxide dismutase (SOD) and peroxidase (POD) in No.1 is significantly higher than that in No.901, while the activity catalase (CAT) does not show any obvious difference between No.1 and No.901. Meanwhile, the lipid soluble antioxidative activity in No.1 is also higher than that in No.901. All the results imply that there exists a close relationship between infection resistance and antioxidative activity in L. japonica. The purpose of this study is to research the biological basis for control of seaweed rot diseases.

Extensions, Profiles, Recipes, Attachments, Objekte und Activities, viele Konzepte sind spezifiziert, die inhaltliche Ausgestaltung aber bewusst offengehalten. Die resultierende Konsequenz ist fehlende Eindeutigkeit. Dieser Beitrag arbeitet diese Problematik strukturiert auf und diskutiert die gegenwärtigen Ansätze verschiedener Registries durch die kritische Betrachtung der Entwicklung des xAPI Standards.
A single gate oxide level shifter for denser digital domain integration in multiple‐supply‐voltage applications

Modern system‐on‐chip (SoC) applications usually employ multiple voltage domains to save power consumption according to the required circuit performance. Typical multivoltage approaches use level shifters (LSs) to establish communication among voltage domains. The use of commercial standard‐cell and multiple gate oxide MOS LSs implies a nonoptimal place‐and‐route process. Here, we introduce a single gate oxide level shifter (SGOLS) that enables full integration into low‐voltage domains. We tested the proposed idea using a commercial digital‐flow tool for a two‐domain SoC integration, achieving an enhancement in the total integration area occupied by LSs of 54% regarding the conventional LS approaches. The proposed SGOLS was implemented in both 65‐ and 180‐nm CMOS nodes, handling voltage differences between the nominal and I/O domain supplies by using just single gate oxide devices. We validated the circuit performance through process, voltage, and temperature (PVT) variations for wide frequency and supply voltage ranges, disclosing an energy‐per‐transition of 416 fJ@180 nm and 93 fJ@65 nm. The introduced LS extends the integration of multiple voltage domains into denser SoCs.
Parental Stress and Prechilling Effects on Pennsylvania Smartweed (Polygonum pensylvanicum) Achenes

Pennsylvania smartweed (Polygonum pensylvanicum L.) achenes were harvested from plants growing either free from competition or in competition with corn (Zea mays L. ‘Pioneer 3780′) plants. Seeds were dormant when harvested. After 15 weeks of prechilling, 4 and 35% of the seeds germinated from plants with and without corn competition, respectively; after 30 weeks of prechilling, more than 92% of all seeds germinated. Scanning electron microscopy revealed that the carpel walls of achenes from plants with corn competition were porous with many channels. Carpel walls of achenes from plants without corn competition were without pores and channels. Transmission electron microscopy showed more lipid bodies in the embryo epidermal cells of seeds from plants with corn competition. Cell walls of embryos from non-prechilled seeds from plants with corn competition contained lipoidosomes that traversed cell walls. Lipoidosomes did not occur in cells of prechilled seeds.
Diet of Rhinopithecus bieti at Xiangguqing in Baimaxueshan National Nature Reserve

From June 2008 to May 2009,we studied the diet composition for an over-large group of the Yunnan snub-nosed monkey(Rhinopithecus bieti)by direct observation and instantaneous scan sampling method at Xiangguqing(27°37'N,99°22'E) in the Baimaxueshan National Nature Reserve,Yunnan Province.The results indicated that the diet composition of R.bieti included 105 plant species in 42 families.The annual diet consisted of 50.6% lichens,16.3% mature leaves,10.5% fruits and seeds,8.4% young leaves,7.9% bamboo shoots,3.0% buds,1.9% flowers,0.8% bark/petiole/stem,and 0.5% fungi.The results also indicated that the monkey consumed more young leaves in spring,and more fruits and seeds in autumn,which suggested their dietary diversity varied seasonally.Bamboo shoots became one of primary foods of R.bieti in summer.We also found that their feeding the 10 families occupied 39.6% of the total,and Rosaceae occupied 17.57%,which showed significantly selectivity for food.Thus,all results suggested that feeding behaviors of R.bieti were significantly influenced by the seasonal variation of diverse foods.
Modifikasi Unsur Hara Makro untuk Peningkatan Keragaan Planlet Stevia rebaudiana dalam Kultur In Vitro

RIZKI ALFIAN. Modification of Macro Nutrients to Increase The Vigor of Plantlet’s of Stevia rebaudiana in In Vitro Culture. Supervised by DIAH RATNADEWI and SUMARYONO. Stevia rebaudiana a shrub that originated from Paraguay, has been developed in many developed countries as natural sweetener to substitute sugarcane. Previous researches that focus on plantlet’s vigor by adding paclobutrazol and applying different light intensities had unsatisfied results. This research aimed to increase stevia plantlet’s vigor by modifying macro nutrients contained in MS and WP media. MS and WP media were used with macro nutrients at half stength, normal and double strength. After four weeks of culture, WP media promoted the growth to better conditions than MS media. WP media was superior in some parameters such as the height, number of nodes, number of roots, class of leaf color, size of leaf and biomass fresh weight, although some parameters such as stem diameter, number of buds, and survival rate ware not significantly different. Increasing the concentration of macro nutrients tended to give negative effect on the parameters. WP media with half-strength macro nutrient in general resulted in a better vigor of stevia plantlet’s.

Relative Dispersion on the Inner Shelf: Evidence of a Batchelor Regime

Oceanographic relative dispersion (based on drifter separations r) has been extensively studied, mostly finding either Richardson–Obukhov () or enstrophy cascade [] scaling. Relative perturbation dispersion (based on perturbation separation r − r0, where r0 is the initial separation) has a Batchelor scaling () for times less than the r0-dependent Batchelor time. Batchelor scaling has received little oceanographic attention. GPS-equipped surface drifters were repeatedly deployed on the Inner Shelf off of Pt. Sal, California, in water depths ≤ 40 m. From 12 releases of ≈18 drifters per release, perturbation and regular relative dispersion over ≈4 h are calculated for 250 ≤ r0 ≤ 1500 m for each release and the entire experiment. The perturbation dispersion is consistent with Batchelor scaling for the first 1000–3000 s with larger r0 yielding stronger dispersion and larger Batchelor times. At longer times, and scale-dependent diffusivities begin to suggest Richardson–Obukhov scaling. This applies to both experiment averaged and individual releases. For individual releases, nonlinear internal waves can modulate dispersion. Batchelor scaling is not evident in as the correlations between initial and later separations are significant at short time scaling as ~t. Thus, previous studies investigating are potentially aliased by initial separation effects not present in the perturbation dispersion . As the underlying turbulent velocity wavenumber spectra is inferred from the dispersion power law time dependence, analysis of both and is critical.

Does keeping the Bakri balloon in place for longer than 12 hours provide favourable clinical outcomes in the treatment of uterine atony

Aim: If the initial treatment techniques fail, intrauterine balloon tamponade (IUBT) devices such as Bakri balloon tamponade (BBT) is an effective treatment for reducing the bleeding in uterine atony patients. However, the duration of the Bakri balloon varies widely in clinical practice, and there is no consensus in this issue. This study aimed to compare the clinical outcomes of the Bakri balloon removed in less or more than 12 hours in patients with severe postpartum haemorrhage (PPH). Materials and methods: This retrospective study included 108 patients who underwent Bakri balloon for severe PPH after vaginal delivery. Patients were divided into two groups as the duration of Bakri balloon 8-12 hours (Group I) and >12 hours (Group II). BBT was considered to be successful if the bleeding was stopped, and the patient did not require additional invasive procedures. Age, parity, gestational week, cause of bleeding, presence of co-morbidity that may increase bleeding (multiple gestation, magnesium sulphate infusion), estimated blood loss (EBL) before and after Bakri balloon, postpartum infection, erythrocyte and fresh frozen plasma requirement and invasive procedure requirement of the groups were compared. Results: In group I, 26 patients (52%) underwent erythrocyte transfusion, and 18 patients (36%) underwent both erythrocyte and fresh frozen plasma (FFP) transfusion. In group II, 28 patients (41.2%) underwent erythrocyte transfusion, and 21 patients (30.9%) underwent both erythrocyte and FFP transfusion. These differences were not statistically significant (p=0.42 and p=0.21, respectively). Bacri balloon was failed to reduce bleeding in one patient (2%) in group I and one patient (1.5%) in group II, and these patients had to undergo invasive surgical procedures (hysterectomy). There was no statistically significant difference between the groups in terms of failed to reduce bleeding rates (p=0.52). Conclusion: Keeping the Bakri balloon in place for longer than 12 hours does not provide favourable clinical outcomes compared to keeping in place for less than 12 hours.
Power Factor Correction in Modified SEPIC Converter fed Switched Reluctance Motor Drive

This paper presents a dual output PFC (Power Factor Correction) converter for switched reluctance motor (SRM) drive. Here, a modified SEPIC (Single Ended Primary Inductance Converter) converter is proposed for wide range of speed control and to achieve power factor correction at AC mains. The switching frequency of the converter is considered at 20 kHz. The converter is designed to operate in DCM (Discontinuous Conduction Mode) of operation, which reduces the size of the output inductor. The DCM mode to obtain PFC, also reduces the sensor requirement as compared to CCM where two voltage sensors and one current sensor, add to the drive cost. The drive is proposed for universal AC mains (90V-270V AC). Simulated and experimental results are demonstrated to validate the performance of the drive during different operating conditions. The input current total harmonic distortion (THD) is reduced to comply an IEC 61000-3-2 standard.

Recent Applications of Magnetic Nanoparticles in Food Analysis

Nanotechnology has become a topic of interest due to the outstanding advantages that the use of nanomaterials offers in many fields. Among them, magnetic nanoparticles (m-NPs) have been one of the most widely applied in recent years. In addition to the unique features of nanomaterials in general, which exclusively appear at nanoscale, these present magnetic or paramagnetic properties that result of great interest in many applications. In particular, in the area of food analysis, the use of these nanomaterials has undergone a considerable increase since they can be easily separated from the matrix in sorbent-based extractions, providing a considerable simplification of the procedures. This allows reducing cost and giving fast responses, which is essential in the food trade to guarantee consumer safety. These materials can also be easily tunable, providing higher selectivity. Moreover, their particular electrical, thermal and optical characteristics allow enhancing sensor signals, increasing the sensitivity of the approaches based on this type of device. The aim of this review article is to summarise the most remarkable applications of m-NPs in food analysis in the last five years (2016–2020) showing a general view of the use of such materials in the field.
Generating Goal-directed Visuomotor Plans with Supervised Learning using a Predictive Coding Deep Visuomotor Recurrent Neural Network

— The ability to plan and visualize object manipulation in advance is vital for both humans and robots to smoothly reach a desired goal state. In this work, we demonstrate how our predictive coding based deep visuomotor recurrent neural network (P-DVMRNN) can generate plans for a robot to manipulate objects based on a visual goal. A Tokyo Robotics Torbo Arm robot and a basic USB camera were used to record visuo-proprioceptive sequences of object manipulation. Although limitations in resolution resulted in lower success rates when plans were executed with the robot, our model is able to generate long predictions from novel start and goal states based on the learned patterns.
