DominoCIM: A 28nm 138.04TOPS/W Spike-Domain Computing-in-Memory 6T-SRAM Macro for AI and Embedded Applications
Authors: Pu XingYu , Zhang YiRan , Guo An , Zhang ZhaoYang , He ShengNan , Si Xin 
Published: June 2023

Abstract
The realization of computing in memory based on SRAM(SRAM-CIM) can be divided into three domains: analog domain (AD-CIM), time domain (TD-CIM), and digital domain (DD-CIM). However, there exist corresponding disadvantages to the above methods. For AD-CIM, the calculation accuracy is poor. Moreover, the output stability of TD-CIM is limited. With a large overhead area, the layout and wiring of DD-CIM are complicated. Aiming to solve the shortcomings, this paper proposes a spike-domain circuit based on a pulse edge counting scheme. The circuit uses digital logic to realize the MAC operation, which is less affected by power, voltage, and temperature (PVT) and performs higher calculation accuracy. The circuit is transmitted serially through the delay chain to achieve a smaller area overhead. At 28 nm, the circuit accomplishes energy efficiency (EF) with 138.04TOPS/W for 4-bit multiplication and addition (MAC) operations, enabling full precision output and 3.42 times less energy consumption per operation than the previous SRAM-CIM.

Published: June 2023

Abstract
Graphene materials have broad development prospects in the field of anticorrosion and heat dissipation of high-heat equipment such as transformers in the State Grid. In this paper, the graphene anti-corrosion coating is used as a thermal interface material, and the thermal resistance and emissivity of the graphene anti-corrosion coating samples are studied by combining the thermal resistance detection of electronic devices and systems with the emissivity measurement technology. The thermal resistance test was carried out on the samples containing 1%–10% graphene anti-corrosion coatings, and the emissivity of the samples at 30 °C, 50 °C, 70 °C, and 90 °C was measured respectively. The experimental results show that the method has important theoretical and application significance for the optimization and application of heat dissipation of graphene materials.

Abstract
The IC industry in the Chinese mainland has encountered the difficulty caused by the embargo on lithography machines in developing state-of-the-art semiconductor IC processes. For the first time, this work fabricates out the HVTFET which we have independent intellectual property rights. A 50 nm channel length N HVTFET device is fabricated successfully using a 0.35 µm process, and its characteristics are close to those of TSMC’s 55 nm planar N MOSFET. The experimental results of this paper have two important significances. First, it shows that the fabrication of the advanced ICs in the Chinese mainland can get rid of the limitation of the lithography machine by using the HVTFET. Second, it shows that it is possible to decrease the chip area by about 3/4 by using the HVTFET structure for the ICs with 28 nm and above planar MOS processes, which are quite common in China.
NOMA-Based Radio Resource Allocation in Vehicular Networks

Published: June 2023

Abstract
The increasing prevalence of intelligent transportation systems necessitates more frequent communication between vehicles and the external environment. Due to the large number of user connections and frequent information exchange in this scenario, higher requirements for both delay and reliability are also imposed and they are crucial to improving spectrum efficiency. In an effort to find a solution to this problem, we advocate a proposal where multiple V2V share the spectrum with each V2I, and we introduce NOMA to enhance spectrum efficiency, mitigate resource collision issues among users, and eliminate the delay overhead resulting from retransmission. In this paper, we propose a three-stage scheme. In addition, we compare the effectiveness of two different OFDM strategies in V2X systems. Simulation results demonstrate that using NOMA can effectively improve the system capacity.
Single-line multi-voltage threshold method for scintillation detectors
Authors: Chu Hyeyeun , Yi Minseok , Shim Hyeong Seok , Lee Jae Sung 
Published: June 2023

Abstract
The multiple thresholds used in multi-voltage threshold (MVT) method provide more detailed information about the pulse amplitude of the input analog pulses than the simple time-over-threshold (TOT) method, thus allowing for better energy estimation and pulse reconstruction capabilities. However, as the number of thresholds increases, the number of comparators and digital signal readout channels required for MVT also increases. This requirement owing to the increased number of thresholds is the main disadvantage of MVT implementation using field-programmable gate array (FPGA)-based time-to-digital converters (TDCs) because the FPGA resources required for TDC implementation are substantial and FPGAs have a limited number of input/output ports. Therefore, we propose a new single-line MVT method to improve the integrity of the FPGA-only data acquisition system without analog-to-digital converters by reducing the FPGA input channels required for the MVT method. The proposed method, which applies three different levels of thresholding, reduces the digital output signal line in the MVT by employing a 3-input XOR logic gate. The XOR gate integrates the output signals from the comparators and generates 1-bit line digital pulse train. We evaluated the energy performance of the proposed single-line MVT method using three different energy estimators. The energy estimates were compared with the ground truth energy calculated using domino-ring-sampler 4 (DRS4)-sampled analog pulses. The proposed method showed virtually equivalent energy resolution to that of DRS4-based pulse digitization method and better energy linearity than the conventional TOT method. Among the energy estimation methods used in single-line MVT, the crossing-point triangular sum method showed the best energy linearity. The proposed single-line MVT method will be useful when data acquisition systems without ADCs are implemented using FPGA-based TDCs. This is because the proposed method alleviates the problem of limited input ports and the numerous resources required for TDCs in FPGAs.

Published: June 2023

Abstract
The Large High Altitude Air Shower Observatory (LHAASO) is located in Haizi Mountain,
Daocheng County, Sichuan Province, with an average altitude of 4410 m. The Wide Field of view
Cherenkov Telescope Array (WFCTA) is one of its three observation arrays. Laser calibration system
for WFCTA consists of 2 nitrogen lasers and 1 Nd:YAG laser system. During the operation of WFCTA,
the outdoor temperature may dropped from 17 °C to about -30 °C, which will bring
serious challenges to the operation of laser calibration system operating in the field. In order
to ensure the stable working environment and remote operation of the laser, we have developed the
LHAASO-WFCTA laser temperature control, remote control and data monitoring system. The fluctuation
of temperature in the box is within 1 °C around the target. The laser temperature control
system was officially put into operation in Sept. 2020. In this paper, the design scheme,
fabrication scheme, comparison of heat dissipation coefficient and test of temperature control
system are introduced. The working data shows that both nitrogen molecule lasers and Nd:YAG laser
temperature control system can achieve stable and long-term operation in high-altitude extreme
field.
Perlite concrete: a review
Authors: Cojocaru A , Isopescu D N , Maxineasa S G 
Published: June 2023

Abstract
The thermal resistance of concrete significantly influences the energy consumption of the building. Consequently, concrete with high thermal resistance can contribute to the envelope’s energy efficiency. In order to obtain the thermal conductivity performance required for the passive house standard using the principles of sustainable development, it is essential to analyze the thermal improvement solutions of the concrete with a low impact on the environment. For this reason, it is necessary to analyze methods of improving concrete’s thermal performance by replacing aggregates with ecological materials like perlite. Perlite is a common term used for a glassy natural volcanic rock used in construction in various mixtures for its fire resistance, low density, and thermal and acoustic improvement properties. While processing raw perlite (cutting, grinding, and fractionation to various sizes), large amounts of powder are collected and stored as waste. Currently, only limited amounts of waste perlite powder are recycled in the construction industry, which urges the efficient use of this waste to limit the impact on the environment. There are various studies about concrete mixtures with perlite from the point of view of structural strength. However, the results are contradictory, influenced by the size of used particles and the replacement levels in the mixture. This article aims to present the current state of knowledge regarding the characteristics of the mixture between concrete and perlite.
Heavy and light masonry walls impact on medium height reinforced concrete frames buildings
Authors: Constantinescu S 
Published: June 2023

Abstract
The paper studies the influence of light weight aerated autoclaved concrete (AAC) partitioning walls to a medium height reinforced concrete structure, in Bucharest (Romania). The building is designed as a framed structure with non-bearing AAC walls placed in certain bays. There is a bearing full bricks masonry wall in one of the bays. Full bricks are used because of its high strength compared to AAC. The aim is to determine the importance of the masonry walls placement, both full bricks and AAC, for the building’s behavior. The analysis points out the structure’s elastic and plastic behavior and also the efforts developed in the non-bearing walls. The bearing masonry wall’s behavior is very important, because the structure is built in a high seismic area. To extend the study, the full bricks wall is replaced with a reinforced concrete one. This is done to see how it impacts the building’s behavior, for both the elastic and plastic stage. The paper concludes that AAC, full bricks and concrete walls placements have a significant influence on the structure.
Flood hazard assessment in Montenegro through the application of two-dimensional hydraulic modelling
Authors: Ostojić M , Ćipranić I , Jevrić M , Sekulić G , Medojević A 
Published: June 2023

Abstract
Floods, induced partly by climate change and partly by the negative impact of human actions, may be regarded as the most common type of natural catastrophe in Montenegro, causing significant economic, ecological, social, and health damage yearly. Therefore, the focal point of flood risk assessment is reflected in properly determining flood hazards. However, within the Montenegrin National flood risk assessment, which is entirely scenario-based, the hazard is treated only by estimating the occurrence probability of a specific scenario. The paper provides an overview of recent efforts to overcome the potential weaknesses of scenario-based risk assessment by constructing hazard maps for all areas of potential significant flood risk in Montenegro. Hazard maps are intended to visualise different flood intensities (e.g., flood depth, velocity, etc.) for selected return periods. Such outputs are generated by two-dimensional hydraulic modelling, which requires extensive work on gathering the available field data, calculating hydrological inputs, building and calibrating the model, and defining uncertainties that may affect the results. The final production of the hazard maps is conveyed by post-processing the computation results in GIS-based software.

Cellulite: Current Understanding and Treatment
Authors: Gabriel Allen , Chan Vivian , Caldarella Marissa , Wayne Tanya , O’Rorke Erin 
Published: June 2023

Abstract
Cellulite is an aesthetically distressing skin condition that manifests as dimples and depressions, producing an uneven surface to the skin. Occurring in 80% to 90% of females, mostly on the thighs, buttocks, and hips, it is associated with profound negative psychosocial and quality of life issues. Its ethiopathogenesis and pathophysiology are likely to be multifactorial and complex and not fully understood. There is no effective treatment for cellulite, although a number of different treatment modalities are available, from noninvasive to minimally invasive. The efficacy of most treatments is unpredictable and improvements in cellulite appearance are short lived, although significant progress has been made with newer treatments. This review provides an update on the current state of knowledge about cellulite, with an emphasis on patient assessment and an individualized treatment approach for optimal results.

Prognostic implications of the extent of downstaging after neoadjuvant therapy for oesophageal adenocarcinoma and oesophageal squamous cell carcinoma
Authors: Kamarajah Sivesh K , Markar Sheraz R , Low Donald , Phillips Alexander W 
Published: June 2023

Abstract

Background
There are few data evaluating the extent of downstaging in patients with oesophageal adenocarcinoma and oesophageal squamous cell carcinoma and the difference in outcomes for a similar pathological stage in neoadjuvant-naive patients. The aim of this study was to characterize the prognostic value of downstaging extent in patients receiving neoadjuvant therapy for oesophageal cancer.

Methods
Oesophageal adenocarcinoma and oesophageal squamous cell carcinoma patients receiving either neoadjuvant chemotherapy or neoadjuvant chemoradiotherapy between 2004 and 2017 were identified from the National Cancer Database. The extent of downstaging was defined as the extent of migration between groups (for example stage IVa to IIIb = one stage). Cox multivariable regression was used to produce adjusted models for downstaging extent.

Results
Of 13 594 patients, 11 355 with oesophageal adenocarcinoma and 2239 with oesophageal squamous cell carcinoma were included. In oesophageal adenocarcinoma, patients with downstaged disease by three or more stages (hazards ratio (HR) 0.40, 95 per cent c.i. 0.36 to 0.44, P &lt; 0.001), two stages (HR 0.43, 95 per cent c.i. 0.39 to 0.48, P &lt; 0.001), or one stage (HR 0.57, 95 per cent c.i. 0.52 to 0.62, P &lt; 0.001) had significantly longer survival than those with upstaged disease in adjusted analyses. In oesophageal squamous cell carcinoma, patients with downstaged disease by three or more stages had significantly longer survival than those with less downstaged disease, no change, or upstaged disease. Patients with downstaged disease by three or more stages (HR 0.55, 95 per cent c.i. 0.43 to 0.71, P &lt; 0.001), two stages (HR 0.58, 95 per cent c.i. 0.46 to 0.73, P &lt; 0.001), or one stage (HR 0.69, 95 per cent c.i. 0.55 to 0.86, P = 0.001) had significantly longer survival than those with upstaged disease in adjusted analyses.

Conclusion
The extent of downstaging is an important prognosticator, whereas the optimal neoadjuvant therapy remains controversial. Identifying biomarkers associated with response to neoadjuvant regimens may permit individualized treatment.
Is breastfeeding duration related to the health of migrant mother–child dyads experiencing homelessness? The ENFAMS cross-sectional survey

Published: June 2023

Abstract

Background
Literature from the general population shows a consensus about the health benefits associated with breastfeeding for both mothers and children. However, studies investigating these issues in the context of homelessness and migration are rare. This research aimed to examine the relations of any breastfeeding duration with health outcomes among migrant mother–child dyads experiencing homelessness.

Methods
Data were collected among sheltered and mainly foreign-born mothers experiencing homelessness, and their children aged 6 months to 5 years, from the ENFAMS cross-sectional survey (n = 481, 2013—Great Paris area). Any breastfeeding duration, along with various health outcomes of both the mother and her child, was ascertained by face-to-face questionnaires administered by trained interviewers to mothers (perceived physical and emotional health and maternal depression) or by trained psychologists to children (adaptive behaviours). Nurses measured weight and height [thus allowing them to calculate body mass index (BMI)] and haemoglobin concentration (mother–child dyad) and maternal blood pressure. Multivariable linear and modified Poisson regression analyses were performed to examine outcome-wide associations between any breastfeeding duration ≥6 months and the various mother–child outcomes.

Results
Any breastfeeding ≥6 months was associated with lower systolic blood pressure in mothers (B = −0.40, 95% confidence interval = −0.68 to −0.12). No association was observed with the other outcomes.

Conclusions
The relevance of supporting breastfeeding to improve mothers’ physical health holds true in the context of migration and homelessness. It is therefore important to support breastfeeding in these settings. Moreover, given the documented social complexity of breastfeeding practices, interventions should take mothers’ socio-cultural heritage and the structural barriers they face into account.
The Swedish intersectoral national public health policy: effects on child and adolescent health
Authors: Bremberg Sven G 
Published: June 2023

Abstract

Background
To improve health, intersectoral cooperation is often advocated. However, only few studies have reported health effects of this approach. Sweden has adopted a national public health policy (NPHP), which focuses on intersectoral primary prevention of disorders and injuries.

Aim
To investigate the effects of the NPHP, on child and adolescent health in Sweden during the period 2000–19.

Methods
In the first step, the most important improvements in disorders and injuries, assessed as DALYs and incidences, were identified using the GBD Compare database. In the second step, primary prevention methods for these disorders and injuries were identified. In the third step, the relative importance of various government agents for these preventive measures was assessed using Google searches.

Results
Out of 24 groups of causes of disease or injury, only two groups demonstrated an incidence decrease: neoplasms and transport injuries. Leukaemia neoplasms might be prevented by reducing parental smoking, reducing outdoor air pollution and having the mother take folate supplements before getting pregnant. Transport injuries might be prevented by speed restrictions, and physically separating pedestrians from vehicle transport. Most of the primary prevention work was done by government agencies, like the Swedish Transport Agency, which worked independently of the National Institute of Public Health.

Conclusion
Governmental agencies outside the health carried out most of the effective primary preventive efforts, almost independently of the NPHP.
