Phase unwrapping is used to establish the mapping relationship between camera and projector,which is one of the key technologies in fringe projection profilometry(FPP)based three-dimensional(3D)measurement.Although complementary Gray code assisted phase unwrapping technology can get a good result on the periodic boundary,it needs more coded images to obtain a high frequency fringe.Aiming at this problem,a complementary binary code assisted phase unwrapping method is proposed in this paper.According to the periodic consistency between the wrapping phase and binary codes,the coded patterns are generated.Then the connected domain strategy is performed to calculate the fringe orders using the positive and negative image binaryzation.To avoid the mistake near the periodic boundary,complementary binary code inspired by the complementary Gray code is proposed.The fringe order correction is also discussed for different situations in the first measured period.Only two binary images are needed in the proposed method,and the fringe frequency is not limited.Both the simulation and experiment have verified the feasibility of proposed method.

E2F transcription factors(TF)comprise a family of proteins that regulate the expression of genes required for S-phase progression,among others.Arabidopsis genome encodes six E2F TFs(E2FA–F),which are classified as typical(E2FA–C)and atypical(E2FD–F)depending on their ability to interact with two DP interaction proteins(DPa and DPb)(Sablowski and Gutierrez,2022).While E2FA–C need to heterodimerize with either DPa or DPb to function,E2FD–F act independently of DP proteins.Moreover,the retinoblastoma-related1(RBR1)protein also binds and inhibits the typical E2F/DP TF complexes when bound to the promoter of genes,repressing their expression in the absence of a signal to enter a new cell cycle.In general,E2FA and E2FB are considered transcriptional activators,while E2FC is generally considered a repressor of cell proliferation(Sablowski and Gutierrez,2022).In addition,it is well documented that E2FB at least,and probably E2FA,can also stimulate the G2/M transition.

In order to achieve rapid and simple non-destructive testing of water trees in materials,a novel water tree characterisation method based on the complementary split ring reso-nators(CSRR)was proposed.The characteristics of circular CSRR and rectangular CSRR were analysed in high-frequency electromagnetic simulation software.The resonant fre-quency of CSRR was found to be correlated to the dielectric constant of the materials.In addition,the lumped equivalent circuit parameters of CSRRs were also calculated and simulated.The results of electromagnetic simulations and circuit simulations achieved good consistency.In the experimental part,sensors based on the two kinds of CSRRs were fabricated and were used to detect the water tree defects in low-density polyethylene samples.The experiment results showed that the method of using CSRR sensors to detect water tree is feasible.

Many active learning methods assume that a learner can simply ask for the full annotations of some training data from annotators.These methods mainly try to cut the annotation costs by minimizing the number of annotation actions.Unfortunately,annotating instances exactly in many realworld classification tasks is still expensive.To reduce the cost of a single annotation action,we try to tackle a novel active learning setting,named active learning with complementary labels(ALCL).ALCL learners ask only yes/no questions in some classes.After receiving answers from annotators,ALCL learners obtain a few supervised instances and more training instances with complementary labels,which specify only one of the classes to which the pattern does not belong.There are two challenging issues in ALCL:one is how to sample instances to be queried,and the other is how to learn from these complementary labels and ordinary accurate labels.For the first issue,we propose an uncertainty-based sampling strategy under this novel setup.

A new partial-SOI （PSOI） high voltage device structure named CNCI PSOI （complementary n＋-charge islands PSOI） is proposed. CNCI PSOI is characterized by equidistant high concentration n＋-regions on the top and bottom interfaces of a dielectric buried layer of a PSOI device. When a high voltage is applied to the device, complementary holes and electron islands are formed on the two n＋-regions on the top and bottom interfaces, therefore effectively enhancing the electric field of the dielectric buried layer （E1 and increasing the breakdown voltage （BV）, alleviating the self-heating effect （SHE） by the silicon window under the source. An analytical model of the vertical interface electric field for the CNCI PSOI is presented and the analytical results are in good agreement with the 2D simulation results. BV and EI of the CNCI PSOI LDMOS increase to 5 91 V and 512 V/μm from 216 V and 81.4 Vμm of the conventional PSOI with a lower SHE, respectively. The influence of structure parameters on the device characteristics is analyzed for the proposed device in detail.

The etiologic diagnosis of cerebrovascular diseases requires non-routine complementary examinations to be performed. Thus, in specific cases, after neuroimaging(computed tomography/magnetic resonance imaging cerebral scan sequences) and neurosonology(Doppler test of the supra-aortic trunks, transcranial echography and echocardiography), which academically allow us to classify the patients according to their etiologic stroke subtype, further examinations must be used to make a correct etiologic diagnostic. The present review aims to update knowledge about the usefulness of the different tests of blood and urine, plain chest radiography, X-ray of the spine, skull and abdomen, lumbar puncture, electroencephalography, evoked potentials, polysomnography, and pathologic examination after biopsy of the artery, skin, muscles, nerves, meninges, and brain, in the management of patients who have suffered an acute stroke.

Background: The use of traditional and complementary medicine (T&CM) is increasing in both developed and developing countries. The school of Persian medicine (PM) in Iran is a comprehensive medical school that is rich in history and has its own special principles, elements, philosophy, and diagnostic and treatment options. Many complementary therapy modalities are also popular and in demand among patients and physicians. The aim of this paper is to provide logic for the policymakers in Iranian medical education to make changes in medical education curricula, particularly on integrating T&CM. Methods: We reviewed the global experience in teaching T&CM to medical students, and highlighting the strengths of PM, described why it is necessary to integrate T&CM into general medicine curricula in Iran. Results: PM is a traditional system of medicine that dates back about 7000 years. Although there are few studies about the safety and effectiveness of PM, research into it has recently been accelerated. There is a suitable opportunity for integrating T&CM with conventional medicine. Physicians should be familiar with T&CM to avoid any contraindications, interactions, and unwanted effects. Conclusion: Traditional medicine is part of Iran's heritage and. thus, needs special attention. Familiarization of physicians with T&CM can help them choose the best treatment options for their patients. To integrate T&CM into the medical education curricula of Iran, a two-credit course has been proposed for implementation across the country.
