Unsupervised deep homography with multi‐scale global attention
Authors: Hu Wei , He Chu , Lin Mingyuan , Zhou Haoyu
Published: June 2023

Homography estimation serves an important role in many computer vision tasks. Depending heavily on hand‐craft feature quality, traditional methods degenerate sharply in scenes with low texture. Existing deep homography methods can handle the low‐texture problem but are not robust for scenes with low overlap rates and/or illumination changes. This paper proposes a novel unsupervised homography estimation method that can simultaneously handle such low overlap and illumination change. Specifically, a powerful module, named global transformer contextual encoder (GTCE) is first designed, together with a correlation encoder to effectively aggregate global contextual information and reduce matching ambiguity between feature maps. Moreover, a hybrid photo‐perceptual loss for unsupervised homography estimation is proposed. The proposed loss function considers alignment information on both pixel level and perceptual level thus helping this network to be more adaptive to various scenes, including normal cases and illumination change cases. The results of extensive experiments on synthetic and real‐world datasets demonstrate the superiority of this proposed method over current state‐of‐the‐art solutions especially on challenging scenes with low overlap rates, repetitive patterns and illumination changes.

Aims. Solar Orbiter launched in February 2020 with the goal of revealing the connections between the Sun’s interior, atmosphere, and the heliosphere. The Solar Orbiter Heavy Ion Sensor (HIS) is a time-of-flight ion mass spectrometer dedicated to measuring heavy ions in the solar wind.

Methods. We present an overview of the first measurements of heavy ion composition from HIS, reviewing the methods used to transform the spectra obtained on board into scientific data products and examining two solar wind case studies as well as the statistical properties of the heavy ion composition observed by HIS. We also carried out a comparison with prior measurements of heavy ions at L1.

Results. The HIS data set provides the first mass- and charge-resolved heavy ion measurements in the inner heliosphere.

Conclusions. These high temporal resolution data have the potential to transform our understanding of the connections between the solar wind and its origin at the Sun, as well as the interaction between the solar wind and the environment around planets, comets, and in the interstellar medium.
Protein Interaction Prediction Method Based on Feature Engineering and XGBoost
Authors: Zhao Xiaoman , Wang Xue
Published: June 2023

Human protein interaction prediction studies occupy an important place in systems biology. The understanding of human protein interaction networks and interactome will provide important insights into the regulation of developmental, physiological and pathological processes. In this study, we propose a method based on feature engineering and integrated learning algorithms to construct protein interaction prediction models. Principal Component Analysis (PCA) and Locally Linear Embedding (LLE) dimensionality reduction methods were used to extract sequence features from the 174-dimensional human protein sequence vector after Normalized Difference Sequence Feature (NDSF) encoding, respectively. The classification performance of three integrated learning methods (AdaBoost, Extratrees, XGBoost) applied to PCA and LLE features was compared, and the best combination of parameters was found using cross-validation and grid search methods. The results show that the classification accuracy is significantly higher when using the linear dimensionality reduction method PCA than the nonlinear dimensionality reduction method LLE. the classification with XGBoost achieves a model accuracy of 99.2%, which is the best performance among all models. This study suggests that NDSF combined with PCA and XGBoost may be an effective strategy for classifying different human protein interactions.

Authors: Xie Wenzhan , Zhang Mingxun , Wang Yafang , Yan Jiaqian
Published: June 2023

Objective: The most important and common psychiatric disorders after stroke include post-stroke depression, which can lead to a variety of negative health outcomes. This study was calculated to estimate the security and effectiveness of acupuncture rehabilitation in curative effects for post-stroke depression patients. Methods: As of July 2022, PubMed, Embase, Web of Science, Cochrane Library, and China National Knowledge Infrastructure were searched through electronic databases. Eligibility criteria RCTs evaluate RCTs of acupuncture rehabilitation on treatment events in depressed patients after stroke, compared to a control group. Results: Eight studies were included (n = 16,422). When combined with antidepressant/sham acupuncture efficacy, acupuncture intervention observably reduced HAMD scores (MD= -0.55,95% CI= -1.57 to -0.48, P=0.30, I²= 0%). Meanwhile, acupuncture rehabilitation also reduced BI scores (MD= 1.87,95%CI= -3.77-7.51, P=0.51, I²= 0%) and CGI-S score (MD=0.43,95% CI = 0.06-0.77, P =0.01, I² = 0%) compared with antidepressants / sham acupuncture. Second, the occurrence rate of combined negative events was dramatically lesser in the acupuncture groups, as indicated by the SERS scores (MD= -4.85,95% CI= 5.67 to -4.04, P <0.00001, I² = 0%) of the acupuncture groups and the antidepressant/sham acupuncture groups. Furthermore, the overall clinical outcome was observably better in the acupuncture groups (MD=1.58,95% CI =0.813.09, P =0.18, I² = 0%). Conclusion: Acupuncture rehabilitation intervention for post-stroke depression is safer and more effective than antidepressant/sham acupuncture.
Diagnostic de l’arthrose chez le chat
Authors: Decambron Adeline
Published: June 2023

L’arthrose est une maladie inflammatoire chronique caractérisée par le développement d’une douleur et d’une perte de fonction articulaires. Des signes d’arthrose sont identifiés chez 22 à 74 % des chats et elle est très généralement polyarticulaire, axiale et appendiculaire. Les signes de douleurs chroniques chez le chat sont progressifs et subtils et peuvent rester non identifiés, d’autant que le chat fait souvent preuve d’inhibition. Il est fréquent que le chat présente des modifications du comportement (tempérament, hygiène, mobilité) et des signes d’hypersensibilité (douleur disproportionnée par rapport aux stimuli). En raison de cette dernière, plus de 30 % des chats arthrosiques montrent une agitation soudaine sans raison apparente, des vocalises, des trémulations musculaires, une irritation au toucher, ou un léchage/mordillement soudain. L’arthrose féline reste sous-diagnostiquée car il n’existe pour le moment pas d’outil unique ayant une sensibilité et une spécificité suffisantes pour permettre d’établir un diagnostic de certitude. Le clinicien doit combiner l’ensemble des informations obtenues par le propriétaire (historique, questionnaire, CMI), l’examen orthopédique et les examens d’imagerie. Concernant ces derniers, le scanner est supérieur à la radiographie. Si toutes les informations de cette triade sont concordantes alors le diagnostic est établi. La présence de 2 paramètres sur 3 entraîne une suspicion et l’épreuve thérapeutique ou d’autres examens complémentaires pourront être proposés.
Entéropathies chroniques du chat, quelles spécificités ?
Authors: Remmel Paul , Freiche Valérie
Published: June 2023

Les entéropathies du chat sont des affections fréquentes dont l’origine peut être infectieuse, alimentaire, dysimmunitaire ou tumorale. Leur présentation est très équivoque et dans de nombreux cas, les signes cliniques orientent vers une atteinte diffuse entérocolique. La précision des signes cliniques reste cependant déterminante dans le choix des examens complémentaires. Les chats jeunes avec des signes cliniques modérés sont le plus souvent atteints par des protozoaires ou par des troubles de la tolérance alimentaire. En présence de diarrhée, une parasitose doit être recherchée par coproscopie sur 3 prélèvements successifs et PCR tritrichomonas. La fibroplasie sclérosante éosinophilique féline est une entité récemment décrite. Elle affecte aussi les jeunes adultes et peut être suspectée lors d’éosinophilie périphérique ou de masse digestive. Chez les animaux âgés de plus de huit ans, le lymphome digestif de bas grade est une cause fréquente d’entéropathie chronique. Les principaux signes cliniques incluent un amaigrissement, une anorexie (ou une polyphagie) et des vomissements. Le diagnostic est histologique selon de nouveaux critères, récemment mieux cernés. Les entéropathies lymphoplasmocytaires, éosinophiliques et les autres néoplasies affectent des chats de tout âge et peuvent s’exprimer par des présentations cliniques variées. L’échographie abdominale couplée à l’examen cytologique en cas d’adénopathie ou de masse digestive constitue une étape préliminaire et essentielle du diagnostic. Si nécessaire, des biopsies digestives soumises à une analyse histologique et immunohistochimique sont déterminantes pour la distinction spécifique entre inflammation chronique et lymphome de bas grade.
Bronchopneumopathies inflammatoires des carnivores domestiques : entités spécifiques, place des examens complémentaires et prise en charge à long terme
Authors: Ruiz Guillaume
Published: June 2023

Les bronchopneumopathies inflammatoires sont relativement fréquentes chez le chien et le chat. La toux est l’expression clinique la plus fréquente de cette inflammation. Une intolérance à l’effort ou des difficultés respiratoires sont également possibles et peuvent affecter de façon significative la qualité de vie des animaux atteints. Il convient cependant de noter que d’autres affections peuvent être à l’origine des mêmes signes cliniques, mais seront traitées de façon différente. La réalisation d’examens complémentaires est donc recommandée afin d’établir un diagnostic de certitude et d’adapter le traitement, qui doit être mis en place le plus tôt possible pour éviter des complications de ces bronchopneumopathies inflammatoires chroniques qui sont parfois irréversibles. Les glucocorticoïdes sont la pierre angulaire du traitement et leur dose et formulation doivent être adaptées au long cours pour limiter les effets indésirables systémiques. Les bronchopneumopathies inflammatoires sont des maladies chroniques, et une communication claire et adaptée avec les propriétaires est cruciale dès le diagnostic pour établir des objectifs réalistes d’amélioration sous traitement, et assurer une bonne qualité de vie à l’animal et la satisfaction de ses propriétaires.
Knowledge and Attitude of Young Married Women Regarding Congenital Anomalies in the Fetus: A Cross-Sectional Questionnaire-Based Study from South-Central India
Authors: Mangla Mishu , Sree Kottu Divya Satya , Kumar Naina , Panda Meely
Published: June 2023

Background Although congenital anomalies are a significant cause of neonatal mortality and morbidity in both developed and developing countries, middle- and low-income countries, including India, account for approximately 95% of all children born with congenital anomalies. Some birth defects/congenital anomalies are preventable, if their risk factors are modified. Young married women must have a good knowledge regarding these preventable risk factors because this is the population who will be bearing children in the near future. Therefore, this study aims to determine the knowledge and attitude of young married women regarding congenital anomalies/ birth defects, their risk factors, preventive measures, and treatment options available.

Materials and Methods An analytical cross-sectional study was conducted in a tertiary care center in South-Central, India, for over 1 year. Five hundred young married women (range: 18–30 years) answered a questionnaire, mainly focusing on what are birth defects, what are their risk factors and preventive strategies against them. It also included questions on how birth defects are diagnosed, and if carrying a baby with birth defects, what they would do for their management and also their knowledge regarding fetal medicine centers and fetal medicine specialists.

Results The mean knowledge score of the study participants was 18 ± 4.08 (range: 8–27). About 82.8% of the study participants had average knowledge regarding birth defects, and only 17.2% had good and adequate knowledge scores. The knowledge regarding risk factors is grossly inadequate. The knowledge regarding advanced maternal age, maternal obesity, and consanguinity as risk factors for congenital anomalies was deficient in more than 50% of the study population. The mean attitude score was 4.42 + 0.985 (range: 1–7), indicating overall positive attitudes.

Conclusion Knowledge regarding birth defects, their risk factors, and preventive strategies was moderate in the majority of the study participants. Education has some bearing on the knowledge and attitude, but the knowledge base still seems to be influenced by religious beliefs. Awareness campaigns to increase the knowledge about preventable causes of birth defects and their management strategies are urgently needed in this region.
Multiple Neonatal Deaths and Alexander's Disease: A Case Report
Authors: Makwana Renu , Makwana Prateek , Thawani Simran , Malleda Neeraja Reddy
Published: June 2023

Factor VII deficiency, also known as Alexander's disease, is a rare bleeding disorder due to homozygous or compound heterozygous mutations in the F7 gene and is inherited in an autosomal recessive manner. The condition manifests as a wide range of symptoms, based on the severity of the disease, and may appear at any age. While family and personal histories are essential for identification of the disorder, there is usually no history due to the autosomal recessive nature of the condition. Here, we report a case of factor VII deficiency in a family that was identified due to multiple neonatal deaths and the importance of genetic counseling and prenatal diagnosis for such scenarios.

Published: June 2023

G-banded karyotyping is the most common approach for the detection of genomic alterations. However, this is unable to detect genomic changes of less than 5 Mb. The ability of fluorescence in situ hybridization (FISH) to detect cryptic chromosomal rearrangements exceeds the resolution of routine karyotype. However, conventional FISH is for targeted regions only, whereas the chromosomal microarray is a whole-genome copy number evaluation technique with a resolution of 10 to 20 kb. In this article, we discuss the application of chromosomal microarray 750 K to 384 consecutive prenatal diagnosis cases. Overall diagnostic yield is 15.36%, and chromosomal microarray accounts for a 3.6% additional detection rate. We suggest applying this technique in routine prenatal diagnosis as a first-tier test in prenatal diagnosis along with a backup culture in all cases.

Authors: Choudhary Dinesh , Sharma Charu , Choudhary Sushil K. , Bhandari Shafaq
Published: June 2023

Hydrops fetalis (HF) is a serious fetal condition characterized by abnormal accumulation of fluid in fetal soft tissues and serous cavities. HF can be immune hydrops fetalis (IHF) or nonimmune hydrops fetalis (NIHF) depending upon the presence of antibodies in the mother. We report a case of euploid NIHF who delivered at 34 weeks and had spontaneous recovery. The baby had gross fetal ascites and mild pleural and pericardial effusion. After a thorough workup, no definite cause could be found. However, the ascites spontaneously resolved. The baby had many peaks and valleys during the initial 3 months of life, doing well at 6 months of age and is under follow-up. This case report highlights the practical workup and diagnostic algorithm of NIHF and provides an updated review.
Healthcare professionals’ editorial opinions on communicating with the public: shifting social media hesitancies
Authors: Alhafez Lina , Rubio-Rico Lourdes , Diez-Bosch Miriam
Published: June 2023

The increasing infodemic, changes in the media landscape, and the COVID-19 pandemic have rendered healthcare professionals’ involvement in social media (SoMe) of urgent need. However, research efforts to understand the opinions, needs, and concerns of healthcare professionals (HCP) tackling this new responsibility have been limited, despite being necessary for designing efficient support for them. In this article we look at varying opinions and attitudes published by HCPs towards the use of SoMe as a tool to communicate health-related information to the public: How did their attitudes develop since the decade preceding the COVID-19 outbreak and what were their main expressed concerns over the years. We conducted a qualitative review of editorials published on this topic in academic journals since 2010 by searching five databases up to December 2022. Thirty-eight (38) articles met the selection criteria. Nineteen (19) expressed a positive attitude, and Nineteen (19) expressed a negative or cautious attitude. Based on the results, the research period (2010–2022) was divided into three stages: 2010–2015, 2016–2018, and 2019–2022. Attitudes in the first stage were positive, the middle was at almost a tie, and the last retreated to negative. The most common concerns cited regarding SoMe use by HCPs are negative effects on physician–patient relationships, HCPs’ professional image, patient privacy, the quality of the information provided, conflict of interest declarations, ethical and legal risks, the perception of medical consensus, limited resources, and competing with entertainment. The editorial opinions of HCPs towards professional SoMe use express shifting hesitancies. The earlier optimism succeeded in an era (pre-2010) of cautioning against engaging with SoMe. Concerns in the first stage were mainly related to HCP´s behavior and use of SoMe. The last phase’s concerns were more oriented toward SoMe platforms, their design, dynamics, and effect on public discourse, with the escalating infodemic and COVID-19 pandemic.
Evaluation of 8 years of fertility control (nicarbazin) to manage urban pigeon populations
Authors: González-Crespo Carlos
Published: June 2023

Context The common pigeon (Columba livia var. domestica) is a synurbic species widely distributed around the world. High local densities of pigeons have negative impacts on animal and public health. Urban pigeon fouling also damages buildings and infrastructures, resulting in increased maintenance costs. Although the reduction of food and shelter would be the most effective control method, it does not apply in most cases where the amount of shelter and food can be unlimited and control very difficult achieve. However, a reduction and control of the population by fertility control using nicarbazin (NCZ, Ovistop®) could be achieved without the need to capture and remove any specimens. Aim and methods The aims of this study were (1) to describe the experience of up to 8 years of use of fertility control by NCZ on pigeon numbers in 24 towns and cities in Catalonia (Spain), (2) to assess the potential for non-target species to be affected by NCZ, and (3) to quantify the costs of implementing local population control of urban pigeons via NCZ. Local number of pigeons was estimated via population censuses. Key results From the beginning of the treatment, a significant steady decreasing trend (average of −12% per year) in the pigeon abundance was registered. In very few instances, non-target birds species were observed to feed on NCZ. Conclusions and implications NZC was an effective and selective method of animal welfare to reduce the total number of pigeons in the municipalities included in this study, while not affecting other non-target species. The estimated cost of the annual treatment was €33.6 per pigeon; in 68% of the municipalities, the total annual cost was halved after 3 years of treatment. The findings of this study are in agreement with previous experiences controlling pigeon colonies by using NCZ in other countries.
Genetic resistance to gastrointestinal parasites in sheep

Published: June 2023

Gastrointestinal nematode (GIN) infection is the most common disease affecting sheep production systems throughout the world, causing significant productive and economic losses. The control of these parasites was traditionally based on the use of anthelmintic drugs. However, continuous, extensive, and indiscriminate use of these drugs has led to the emergence and spread of strains of parasites resistant to the major chemical compounds used. This situation has led to considering alternative strategies for worm control. One of them is the selection of individuals for greater resistance to GINs. A number of phenotypic traits have been reported in the bibliography, including parasitological, biochemical, hematological, and immunological traits, but fecal egg count (FEC) is considered the primary and most practical measure of resistance. Genomic studies have reported polymorphisms associated with GIN resistance traits on almost all sheep chromosomes. Among other loci, FEC has been associated with the major histocompatibility complex (MHC) through quantitative trait loci (QTL) analysis and genome-wide association studies (GWAS). This review covers the principal aspects reported in the literature on several parameters considered to evaluate the resistance status of sheep to nematodes, mainly
Haemonchus contortus
, the correlation between resistance markers with economically important production traits, and the main genomic regions identified as relevant in determining the phenotype for resistance or susceptibility to GINs.

Published: June 2023

While studying the transmission of zoonotic infection in western Kenya, and surveying animals at slaughter to gain insights into disease prevalence, we developed a community-requested programme to understand the occupational risks to which slaughter facility workers are exposed. This led to a series of linked investigations focused on human and animal health centred on the slaughter facility, and a number of public health interventions targeting workers. Here, we summarize the different aspects of this work and the importance of engaging with different sections of the community. We illustrate how the work has integrated an understanding of the slaughter facility microenvironment, human and animal health, and pathogen surveillance within the food system.

Prototypical Validity and Factor Structure of the French Version of the Comprehensive Assessment of Psychopathic Personality (CAPP) Model
Authors: Delannoy Denis , Saloppé Xavier , Cooke David J. , Pham Thierry H.
Published: June 2023

In a study undertaken to examine the content validity of the French-language version of the Comprehensive Assessment of Psychopathic Personality (CAPP), a lexically-based conceptual model and clinical assessment of psychopathy, 204 French-speaking mental health professionals rated the symptoms covered by the CAPP for prototypicality. The majority of the symptoms were deemed to be “moderately” to “highly” prototypical of psychopathy. Of the model’s six domains, Dominance, Attachment and Self were considered more prototypical than Emotional, Behavioral and Cognitive. Results were consistent with those of other prototypicality studies. Descriptives analyses suggested that the ratings of English-speaking mental health professionals were higher than their French-speaking counterparts. However, the effect sizes were small according to the Cohen’s d analyses. Confirmatory factor analysis revealed that Attachment was the only unidimensional domain. Finally, exploratory factor analysis yielded three factors— Egotism, Interpersonal rigidity, and Lack of responsibility. These factors were primarily underpinned by symptoms that entailed interpersonal and social cognitive traits.
Thermally/mechanically robust anodic aluminum oxide (AAO) microheater platform for low power chemoresistive gas sensor
Authors: Lee Byeongju , Cho Incheol , Kang Mingu , Yang Daejong , Park Inkyu
Published: June 2023

The semiconductor metal oxide gas sensors are getting high attention owing to their high sensitivities and fast responses. They require high temperature for the reaction with target gases, and suspended silicon membrane microheaters are typically used to reduce the heating power consumption. However, they have low durability for long-term uses, and high probability of fracture by thermal stress or mechanical impact. In this study, as an alternative to the silicon membrane microheater, anodic aluminum oxide (AAO)-based microheater platform gas sensor was fabricated for low power consumption and high thermal/mechanical stabilities. Nanoscale air gaps of the AAO substrate reduce the heat loss transferred to the substrate. Therefore, AAO-based microheater platforms do not require suspended structures sustained by very thin bridges, which dramatically enhances thermal/mechanical stabilities. The temperature of fabricated microheater platform reached to 250 °C by a heating power of 27.4 mW. The excellent thermal/mechanical stabilities of the AAO-based microheater platforms were verified by cyclic on-off and mechanical shock test. The pulsed heating operation was adopted, and it reduced the heating power consumption to 9 mW. The fabricated AAO-based gas sensors showed much higher responses to NO2 gas compared to the SiO2 membrane-based gas sensors.
High-Q terahertz bandstop filter via cuboid frame structure
Authors: Li Tong , Wang Zhenlong , Li Songlin , Li Yang , Yang Xiaotao , Zhang Jia
Published: June 2023

A terahertz (THZ) bandstop filter can be used to filter interference signals in a filter passband. The quality factor (Q) is the most important index in evaluating the transmission performance of the filter. Usually, a higher Q value, a narrow bandwidth and a larger stopband slope ensures good filtering accuracy and transmission response. However, the Q value taken from metamaterial structures designed on the plane is only ever in single digits, resulting in a less than satisfactory filtering performance. Herein, a high-Q THZ bandstop filter based on metamaterials was proposed. To fabricate this 3D metamaterial structure, a microtopographic substrate-guided method with feasible and high accuracy capacities was proposed. As a result, it is ascertained that the device is in the filtering state in the range 1.038–1.102 THz while it is stopped in the range 1.062–1.066 THz. The similarity between the experimental and simulated transmissions is up to 86.32%, indicating that the fabricating method possesses high accuracy. Accordingly, the Q value was calculated to be as high as 532. In future, the bandstop filter with this record Q value can be widely used in THZ detection, imaging and sensing. Meanwhile, the proposed fabrication method is effectively applied to a 3D metamaterial and a THZ device as well.

In this paper, we introduce a new non-Gaussian state called superposition of photon-added pair coherent state (SPAPCS) by superposition addition of photons to two modes of a pair coherent state (PCS). It is demonstrated that the SPAPCS has an enhanced non-Gaussian property by testing its Wigner function when increasing the number of photons added to two modes of the PCS. We use the field as a SPAPCS to study a dynamical entanglement in a dispersive two-mode Jaynes–Cummings model in dissipation atom-field interaction. We detect the dynamical entanglement degrees of the global system and subsystems by using the linear entropy criteria. The obtained results show the dynamical entanglement degrees can be enhanced by the phase damping effect as well as the superposition adding photons to two modes of the field in SPAPCS.

Cyclo[18]carbon has received considerable attention thanks to its novel geometric configuration and special electronic structure. Superalkalis have low ionization energy. Doping a superalkali in cyclo[18]carbon is an effective method to improve the optical properties of the system because considerable electron transfer occurs. In this paper, the geometry, bonding properties, electronic structure, absorption spectrum, and nonlinear optical (NLO) properties of superalkaline M
3O (M = Li, Na)-doped cyclo[18]carbon were studied by using density functional theory. M
3O and the C18 rings are not coplanar. The C18 ring still exhibits alternating long and short bonds. The charge transfer between M
3O and C18 forms stable [M

We show that certain thermodynamic quantities that are notoriously ill defined (or trivial) in ordinary blackbody thermodynamics are now well defined (or nontrivial) due to the presence of boundary conditions at the walls of the slab (‘Casimir’s effect’). The relationships among such quantities are fully explored and it is speculated that they may be experimentally checked. Stability is addressed, showing that electromagnetic radiation in the slab is thermally stable; but mechanically unstable. We investigate thermodynamic processes where temperature, internal energy, entropy and enthalpy are each taken to be constant, revealing rather atypical behaviors. For example, in sharp contrast with what one would expect from a gas, when

We study the dynamics of a chirality reversing active Brownian particle (ABP), which models the chirality reversing active motion common in many microorganisms and microswimmers. We show that, for such a motion, the presence of the two time-scales set by the chirality reversing rate γ and rotational diffusion constant

Authors: Zhou LiLi , Jiang Feng , Li YeJie , liu JiaYing , Zhang JiaShuo , Gu Yang
Published: June 2023

This design is based on the STM32F103C8T6 mask recognition and temperature monitoring system, mainly including the mask recognition module based on the K210 chip, non-contact infrared temperature sensor module based on the ATmega328P chip, liquid crystal display module, infrared tube sensor module and buzzer module. When the infrared tube sensor senses the measured target, the system starts to supply power to ATmega328P. The infrared temperature measurement sensor module MLX90164 is used to measure the temperature of the target. At the same time, the temperature data is displayed on the LCD1602 display screen. If it exceeds the predetermined value, an alarm will be issued. When the temperature is normal, the system starts to supply power to K210, start the camera, lock the face position, identify whether the target is wearing a mask, and display the measured results through the 2.4-inch TFT screen. If the mask is worn correctly, the face frame will turn green. Through the software program, the three chips are mobilized for coordinated operation, the target body temperature is measured by using the temperature compensation algorithm, and the mask recognition is carried out by using the YoloV2 algorithm. The hardware design and software program design are improved, and finally, the material object is made. After repeated debugging of the real object, the expected effect is finally achieved. After gradual product improvement, it will be widely used in the daily monitoring of mask wearing identification and body temperature detection in the normalization of epidemic prevention and control in public places in the future.

Authors: Wu Huizhen , Chen Qunchao
Published: June 2023

This paper presents an input surge protection circuit for automotive electronics systems with an adjustable overvoltage protection threshold suitable for high input voltage applications. Compared with the conventional overvoltage protection circuit, it boasts a new high-voltage bandgap reference circuit design without pre-regulation, which takes up less space and can be used on a limited PCB board, expanding the practical application range of the chip. The gate protection circuit can monitor the gate-source voltage of the power MOS in real-time and control the charge pump’s operating mode to improve the system’s safety. The design and simulation of the circuit adopt the 0.18 μm 5V/25V BCD process. The simulation results show that the bandgap reference voltage varies by only 0.38 mV in the input voltage range of 3.5 V-25 V. The quiescent current is 146 uA at 5 V supply voltage. The power MOS can be turned on quickly within 50 us. The overvoltage response time is 599 ns, permitting the circuit to be shut down when a surge occurs.

In this study, the STM32 microcontroller is used to drive a passive matrix (PM) Micro-LED through two-wire serial transmission and row-column integration. STM32 exhibits superior properties, including simple-to-operate, cost-friendly, and flexible programming. Moreover, it has a lower cost and more straightforward implementation for testing the quality of the device and realizing the graphics. In this design, the connection between the STM32 and the PM array is realized by an LED driver board and flexible printed circuit (FPC) structure. The two-wire serial protocol and row-column integration are adopted, which not only optimizes the circuit structure but also avoids coupling problems. Compared to the existing structures, it is more concise that only four connecting wires are required to transmit data in display devices of any resolution. Besides, the problem of graphics distortion is solved through two buffers to form a data handshake. Using this method, the blue PM array, which has a resolution of 48 × 48, a refresh rate of 60 Hz, a pixel size of 300 μm, and a luminous area of 50 μm, is successfully realized. In addition, p-metal fractures caused by the bulge in the p-lines are also resolved by adding the GaN as a raised substrate.

Published: June 2023

In this paper, an ultrafast high voltage pulse generator based on power MOSFETs delay push-pull structure is designed. The two complementary power MOSFETs are connected in the push-pull circuit and driven by the low-power MOSFETs separately. The output ultrafast high-voltage pulse amplitude is +30 V ~ -200 V, and the front edge and back edge times of the pulse are 5 ns and 4 ns, respectively. The width and frequency of the output pulse are controlled by the external trigger input signal. The shortest output pulse width is 12 ns and the maximum operating frequency is 100 kHz while the load is 10 pF. The delay conduction method of power MOSFETs is helpful to reduce power dissipation and improve the reliability of the circuit at a high operating frequency.
Design of a multi-modulus divider with a wide frequency dividing range and low power consumption
Authors: Zhao Minxiong , Huang Jiwei
Published: June 2023

A method of moduli expansion was presented to address the issue of wrongly altering the divider ratio at the boundary of the modulus expansion when multi-mode dividers (MMD) were utilized in fractional-N phase locked loops (PLLs). The multi-mode frequency divider was designed as the cascade of the 2/3 frequency dividers with an RS control terminal. Compared to traditional methods, only one OR gate is required for each modulus expansion, reducing the chip area. The 2/3 divider was designed using a True Single-Phase Clocked (TSPC) D-trigger structure, and each D-trigger uses a logic control technique with clearing and setting the number. An eight-stage multi-mode frequency divider with modulus expansion was developed using SMIC 55 nm CMOS technology. The simulation results demonstrated the large frequency divider range of the multi-mode frequency divider and its ability to carry out consistent switching operations over the 8–511 frequency divider range. The power consumption is 66.04W at a supply voltage of 1V, an input frequency of 2GHz, and an output frequency of 250MHz.

Published: June 2023

In this work, we presented a comprehensive investigation of the trapping effect in the GaN-based high-electron-mobility transistors (HEMTs) under the negative gate-source voltage condition. The trapping mechanisms in the OFF state were analyzed and the trapping behaviors were characterized using the pulsed measurements preliminarily. Specifically, the transient drain-source voltage curves under a certain filling condition were monitored to reflect the trapping effect in the OFF state. The spectra of time constant and differential amplitude were combined to obtain the information on traps. Three traps with activation energys of 0.467, 0.552, and 0.067 eV were characterized using the transient drain voltage curves under different temperatures. The trap characterization methods may be useful for the further study of the trapping behaviors and can be helpful for the improvement of the reliability of the devices.
