Unified InterPlanetary Smart Parking Network for Maximum End-User Flexibility

Technological breakthroughs have offered innovative solutions for smart parking systems, independent of the use of computer vision, smart sensors, gap sensing, and other variations. We now have a high degree of confidence in spot classification or object detection at the parking level. The only thing missing is end-user satisfaction, as users are forced to use multiple interfaces to find a parking spot in a geographical area. We propose a trustless federated model that will add a layer of abstraction between the technology and the human interface to facilitate user adoption and responsible data acquisition by leveraging a federated identity protocol based on Zero Knowledge Cryptography. No central authority is needed for the model to work; thus, it is trustless. Chained trust relationships generate a graph of trustworthiness, which is necessary to bridge the gap from one smart parking program to an intelligent system that enables smart cities. With the help of Zero Knowledge Cryptography, end users can attain a high degree of mobility and anonymity while using a diverse array of service providers. From an investor’s standpoint, the usage of IPFS (InterPlanetary File System) lowers operational costs, increases service resilience, and decentralizes the network of smart parking solutions. A peer-to-peer content addressing system ensures that the data are moved close to the users without deploying expensive cloud-based infrastructure. The result is a macro system with independent actors that feed each other data and expose information in a common protocol. Different client implementations can offer the same experience, even though the parking providers use different technologies. We call this InterPlanetary Smart Parking Architecture NOW—IPSPAN.
The Effects of Intergenerational Transmission on Education

Late Triassic dinosaur tracks from Penarth, south Wales

Abstract Evidence of Late Triassic large tetrapods from the UK is rare. Here, we describe a track-bearing surface located on the shoreline near Penarth, south Wales, United Kingdom. The total exposed surface is c. 50 m long and c. 2 m wide, and is split into northern and southern sections by a small fault. We interpret these impressions as tracks, rather than abiogenic sedimentary structures, because of the possession of marked displacement rims and their relationship to each other with regularly spaced impressions forming putative trackways. The impressions are large (up to c. 50 cm in length), but poorly preserved, and retain little information about track-maker anatomy. We discuss alternative, plausible, abiotic mechanisms that might have been responsible for the formation of these features, but reject them in favour of these impressions being tetrapod tracks. We propose that the site is an additional occurrence of the ichnotaxon Eosauropus, representing a sauropodomorph trackmaker, thereby adding a useful new datum to their sparse Late Triassic record in the UK. We also used historical photogrammetry to digitally map the extent of site erosion during 2009–2020. More than 1 m of the surface exposure has been lost over this 11-year period, and the few tracks present in both models show significant smoothing, breakage and loss of detail. These tracks are an important datapoint for Late Triassic palaeontology in the UK, even if they cannot be confidently assigned to a specific trackmaker. The documented loss of the bedding surface highlights the transient and vulnerable nature of our fossil resources, particularly in coastal settings, and the need to gather data as quickly and effectively as possible.
Production of English lexical stress by Mandarin speakers: Acoustics and kinematics

This study aims to understand if Mandarin late learners of English can successfully manipulate acoustic and kinematic cues to deliver English stress contrast in production. Mandarin (N = 8) and English (N = 8) speakers were recorded producing English trochaic (initial stress) and iambic (final stress) items during a nonword repetition task. Speakers’ jaw movement for the utterances was tracked and analysed. Acoustic and kinematic cues were measured for each syllable, including acoustic duration, fundamental frequency (F0), and intensity, as well as jaw movement duration, displacement, peak velocity, and stiffness. Stress ratios (syllable 1 / syllable 2) were calculated for each cue and compared between groups. Results showed that English and Mandarin speakers had generally comparable performance in differentiating trochaic from iambic patterns, as well as in the degree of between-syllable contrast within each pattern. Between-group differences were only observed in acoustic duration and jaw movement velocity/stiffness. These results suggest that the experience with Mandarin stress contributes to Mandarin speakers’ overall successful production of English stress but also results in nonnative use of some acoustic/kinematic cues.
SynLethDB 2.0: a web-based knowledge graph database on synthetic lethality for novel anticancer drug discovery

Two genes are synthetic lethal if mutations in both genes result in impaired cell viability, while mutation of either gene does not affect the cell survival. The potential usage of synthetic lethality (SL) in anticancer therapeutics has attracted many researchers to identify synthetic lethal gene pairs. To include newly identified SLs and more related knowledge, we present a new version of the SynLethDB database to facilitate the discovery of clinically relevant SLs. We extended the first version of SynLethDB database significantly by including new SLs identified through CRISPR screening, a knowledge graph about human SLs, and new web interface, etc. Over 16,000 new SLs and 26 types of other relationships have been added, encompassing relationships among 14,100 genes, 53 cancers, and 1,898 drugs, etc. Moreover, a brand-new web interface has been developed to include modules such as SL query by disease or compound, SL partner gene set enrichment analysis and knowledge graph browsing through a dynamic graph viewer. The data can be downloaded directly from the website or through the RESTful APIs. The database is accessible online at http://synlethdb.sist. shanghaitech.edu. cn/v2.

High-speed bit-error-rate measurement system for high-temperature superconducting digital circuits

We have investigated and tried to improve the packaging technologies for a bit-error-rate (BER) measurement system for high-T/sub c/ superconducting circuits. Signal cables, test fixture, and magnetic shields were specially designed and assembled for the BER measurement system, taking into account electrical losses, signal reflection, heat inflow, and power consumption of a cryocooler. BER was further improved by changing the way of connection between the semiconductor amplifiers outside the sample vacuum chamber. These improvements led to a BER less than 10/sup -12/ at an output voltage (V/sub out/) of 1.7 and 2.3 mV for a 50-/spl Omega/ standard microstrip transmission line and a superconducting microstrip-line to coplanar-waveguide transmission-line converter, respectively. The temperature rise of the test fixture was as low as about 2 K. These values are approximately one order of magnitude smaller than those in the previous measurement system and small enough to be achieved by using superconducting interface circuits. Furthermore, 1-Gb/s operation of a superconducting quantum interference device array-type interface circuit was demonstrated in the BER measurement system at 40 K.
Methods for dielectric reconstruction in microwave tomography

In this paper an iterative electromagnetic time-domain inversion algorithm is described and modified to include a priori data of the shape and dielectric properties of an object being imaged. The algorithm is based on solving the regular and the adjoint Maxwell's equations in order to compute gradients, which are used to update the dielectric profile with the conjugate-gradient method. As an alternative a global optimisation algorithm, the particle swarm optimisation method, has also been investigated. The results show that by exploiting a priori dielectric data in this way a significant improvement in the resolving ability can be obtained. Finally Tikonov and edge preserving regularisation has been investigated and a modified regularisation scheme, supporting the a priori data is suggested.
Flexible multivariable design procedure for optimum operation of the Class-E amplifier using state space techniques

The Class-E amplifier is a highly efficient tuned switching power amplifier with a linear drain amplitude modulation characteristic ideally suited for high-efficiency amplifier systems (e.g., Kahn-amplifiers). This brief describes a design procedure to determine the circuit elements for optimum operation of the amplifier using state space methods. Finite feed inductance and quality factor of the resonant circuit are taken into account. It is shown that high efficiency can be sustained for a wide variety of element combinations, allowing relaxed demands on the output capacitance of the active device. This is especially useful for high-frequency amplifiers where the maximum operation frequency of a given device is often limited by its intrinsic drain-source capacitance.
Amplified pixel sensor architectures for low dose computed tomography using silicon thin film technology

Cone beam computed tomography (CBCT) has been recently reported using flat panel imagers (FPI). Here, detector technology capable of high speed imaging, high spatial resolution, large volume coverage, better contrast resolution and, in particular, lowered patient dose is required. Employing active matrix flat panel imagers (AMFPIs) as cone beam CT detectors has been proposed as a solution for improving volume coverage, contrast and resolution; however, clinical evaluations have shown that they suffer from low speed read out. Unlike passive pixel architecture which is currently the state-of-the-art technology for AMFPIs, our preliminary studies have shown that novel amplified pixel sensor (APS) architectures can overcome the low readout speed, and moreover, they provide gain which can be traded for higher frame rate and lower X-ray doses. Although APS architectures can meet the high dynamic range and low noise requirements of CT imaging, linearity and variations between pixel characteristics are major issues. In this study we will investigate novel APS architectures to address these concerns.
Analytical solutions for optimal ride comfort and tyre grip for passive vehicle suspensions

The paper derives analytical solutions for the global optimum of the ride comfort and tyre grip performance measures for a quarter-car vehicle model optimised both individually and in combination. The solutions are derived for six simple suspension networks comprising one or two springs, one damper and possibly one inerter. The solutions are functions of four vehicle parameters: the sprung mass, the unsprung mass, the tyre stiffness and the static stiffness, of the suspension.
Aeronautic behaviour in the wasp-like spider, Argiope brue1lnichi (Scopoli) (Araneae, Argiopidae)

Aeronautic behavionr, aerial dispel·saI. ballooning, spidel's, Argiope bruellllic/ti rnicrorneteorology Abstract. In only a few decades, A. brllennichi has colonized vast areas of continental Europe. This was most likely achieved by the ballooning of young spiderlings. Its original distribution was largely restricted to the Meditenanean. This makes A. brllennichi an interesting object for studying the proximate factors, behavioural and micrometeorologicaL which lead to this rapid mode of dispersal. After eclosion fi'om their cocoons on sunny days in spring. the spiderlings climb into the top of vegetation. Two modes of take-off can be observed. The most common method is by stal1ing tl'om the top of a grass haulm. However, if many spiderlings have emerged ti'om their cocoons, they will start from a "trapeze", a diffuse construct of silken threads connecting grass blades. In both cases they initiate ballooning by dropping on its dragl ine. As no aggregations of orb webs were detected in the direct proximity of the cocoons jj'om which spiderlings eclosed, and their first orb web was only constructed after a ballooning trip, we consider aeronautic behaviour to be an obligatory dement of A. bruennichls life cycle in southern Germany. With respect to the micrometeorological conditions, it appeared that ballooning activity correlated highly significantly with weather conditions causing thennals, which A. bruennichi is apparently able to perceive. The factors which could ultimately be responsible tor the rapid invasion of large pat1S of Europe are discussed briefly.
Gate-overlapped lightly doped drain poly-Si thin-film transistors for large area-AMLCD

We have fabricated a gate-overlapped lightly doped drain (GO-LDD) polycrystalline silicon thin-film transistor (poly-Si TFT) applicable for large area AMLCD by employing the uniform and low-temperature doping techniques, such as ion shower doping and in situ doping. Experimental results show that the leakage current of the proposed TFT's is reduced by more than the magnitude of two orders, compared with that of conventional nonoffset TFT, while the ON current is scarcely decreased. It is verified by the device simulator that the electron concentration in the LDD region is increased under the ON state and decreased under the OFF state due to the field plate with gate potential over the LDD region. Furthermore, the vertical peak electric field in the LDD region is decreased significantly by the extended field plate potential during the OFF state. It is observed that the gate bias stress degrades significantly the subthreshold slope of the ion shower doped GO-LDD TFT's at the low drain bias but does not degrade the device characteristics of those with in situ doping due to the high-quality TEOS SiO/sub 2/ interlayer.
Estimating Streambed Conductivity: Guidelines for Stream-Aquifer Analysis Tests

Significant research in the last several years has improved the capability of hydrologists to analyze stream/aquifer interaction during alluvial well depletion. Analytical solutions are suggested as a means for inversely estimating aquifer and streambed parameters from an aquifer test performed next to a stream. Drawdown measured in one or more observation wells located between a pumping well and stream and/or stream depletion measurements can be matched to predictions of the analytical solutions. However, only a few tests have been documented in the literature. This article reviews analytical solutions for stream/aquifer interaction during alluvial well depletion, discusses prior stream/aquifer analysis tests, and provides guidelines as to the hydrologic conditions when these tests are appropriate. Guidelines are provided for several hydrologic considerations: general site characteristics (i.e., aquifer and streambed properties such as the transmissivity, T, storage coefficient, S, and streambed conductance, λ), time required for the test (t*), distance between stream and pumping well (L), location of observation wells (x/L and y/L), stream stage and stream length (Ls,SAA) requirements, and stream/aquifer hydraulic connection. As the desired prediction interval for streambed conductance decreases (i.e., greater accuracy), the required time for the stream/aquifer analysis test increases. The required test design time, t*T/(SL2), increases as the observation wells are located farther from the stream, with differences of as much as t*T/(SL2) = 0.3 for x/L = 0.1 and x/L = 0.5. As λL/T decreases, a greater ratio of stream length (Ls,SAA) to distance between the pumping well and stream (L) is required. For λL/T > 5.0, a ratio of Ls,SAA/L = 10 guarantees appropriate stream lengths for almost all test design times. However, for λL/T 100. Figures developed in this research can be used to design stream/aquifer analysis tests.
Switching Cell And Measurements In Converter Averaged Models

This paper shows that the parameters of advanced averaged models of power converters to represent the nonlinearities of semiconductor devices are independent of DC-DC converter structures, thus they may be identified experimentally on a unique simple circuit. Experimental results on various converters are compared to accurate simulations. Traditional converters DC-DC can well be simplified on a cell converter, concept largely frequently and offered by the perfect switches concept [2]. We show’s that a so-called switching cell be easily identified from the converter circuit and we demonstrate that power device has the same behavior during cell and the original converter.
Cat-scratch disease in young male: a case report

Cat scratch disease (CSD) is an infectious disease caused by infected cat when it scratches a person hard enough to break the surface of skin. Although it’s a rare disease, the frequency of disease is 1 in 10,000 people. Here we are presenting a case of CSD which was diagnosed with the help of HPE and confirmed by history of scratch from patient’s pet cat. The patient was successfully treated with antibiotic therapy without any complications. However, prognosis is generally good, negligence of disease may lead to serious complications. A correlation of detailed history with clinical presentation as well as high index of suspicion will aid in accurate diagnosis of CSD.
The effects of the job retention programme during the Covid pandemic on the Chilean firms and households

ABSTRACT During the pandemic, several countries implemented job retention programmeswith the goal of preserving human capital and supporting a quick recovery. This work uses administrative records to show the impact of the job retention programme in Chile across firms of different industries and sizes. Using a calibrated model based on survey data of households and our administrative register of workers-firms, we then show that the Chilean Employment Protection Law increase aggregate consumption by 0.3% and helped to smooth household consumption during the period between March of 2020 and March of 2021.
The Influence of Air Gaps At 0.4 Duty Cycle on Magnetic Cere Type 'E' to Increase the Efficiency of Cuk Converter

Cuk converters are used in various electro-technical applications because it is useful for automatic controller. Recently the controller relies with the conventional Pulse Width Modulation (PWM) which use Insulate Gate Bipolar Transistor (IGBT). IGBT has several advantages such as good voltage regulation; however it needs higher cost and the cuk converter efficiency is not optimum. In this paper, we proposed a Cuk converter with a magnetic core as a replacement of PWM with IGBT. Three magnetic cores type "E" are utilized by inserting air gaps in the feet. The first magnetic core type has an air gap at all feet. The second has an air gap at the left and right feet, where the third type has an air gap at the middle and right feet. In order to optimize the inductance and capacitance quantity of the magnetic core, the air gaps as parasitic effect are used. The air gaps used are varied from 0.075 mm to 2.45 mm. The magnetic core is made from Alnico with duty cycle of 0.4. The result of this research is, the third magnetic core type shows the optimum result, giving flux to 0.0098 Wb and efficiency of 94%. This type is designed with air gap 0f 0.19 mm at the middle feet and 0.254 mm at the left foot.
