Effective Analytical Placement for Advanced Face-to-Face-Bonded Circuit Designs

3D chip integration technology, which consists of bonding terminals as die-to-die vertical connections, has attracted a lot of attention due to its many benefits over monolithic integration technology. Compared to previous through-silicon vias (TSVs) interconnects, the recent advancement in face-to-face (F2F) bonding 3D ICs technology can provide better fine-grained and silicon-space overhead-free 3D interconnections. The F2F bonded structure brings a new sweet spot for 3D integration technology while bringing critical challenges for placement algorithm design at the same time. In this paper, we present an effective algorithm to address this F2F-bonded 3D placement problem in several stages. First, a hypergraph partitioning technique using a multilevel framework is used to obtain an appropriate partitioning result under architecture constraints quickly. Then a multi-layer objective function based on an electrostatics model is used to co-optimize the objective over multiple layers. Finally, abacus-based legalization and detailed placement with cell-matching techniques are adopted to optimize the results further. Compared with the winner of the ICCAD 2022 CAD Contest, experimental results show that our algorithm can achieve comparable final total wirelength and 3.41× speedup.
Minimap2 parallelization method based on distributed computing

Gene sequencing is a key technology in the fields of public health and healthcare. The latest third-generation sequencing technology, nanopore sequencing, was widely used after Oxford Nanopore Technologies (ONT) launched its first commercial nanopore sequencer in 2012. Its portability and fast have made it widely applicable. Minimap2 is a universal fast sequence alignment algorithm proposed in 2018 for third-generation sequencing data, specifically designed for long read long sequences obtained from third-generation sequencing. However, for a large amount of data, the single-machine Minimap2 still has the problem of slow speed. This article will introduce various distributed parallelization schemes of the Minimap2 algorithm, and use the Spark framework to achieve distributed Minimap2 sequence alignment in a Hadoop cluster environment. The final results show that under the same data operation, the running speed of the distributed Minimap2 algorithm in a dual node cluster has increased by about 54.5% compared to the original Minimap2 algorithm, And as the number of nodes increases, the running speed can be further improved.
Sliding-mode Model Predictive Control for PMSMs with Current Compensation

Model predictive control (MPC) methods are widely used in permanent magnet synchronous motor (PMSM); however, How to minimize the impact of system delay and motor parameter perturbation on the operation of PMSM is the key to constrain the MPC. To address the problem of current disturbance caused by system delay and motor parameter perturbation, we will propose a series of sliding modes to suppress current disturbances caused by above reasons. Besides, The PMSM model is used to analyse the causes of system delay. Then, the current disturbance caused by parameter perturbation is introduced into the adaptive sliding mode control algorithm for suppression, and the relevant theoretical proof is given. Finally, the effectiveness of the overall scheme is verified through simulations.
DF-TEE: Trusted Execution Environment for Disaggregated Multi-FPGA Cloud Systems

Multi-FPGA systems have recently been deployed in modern data centers to accelerate large-scale, computation-intensive cloud applications. Meanwhile, recent studies promote resource disaggregation as an emerging trend in data center infrastructure enabling high flexibility and utilization of cloud computing resources, including FPGAs. While the community has mostly focused on the management and performance optimization aspects of disaggregated multi-FPGA systems, the security challenges caused by the emerging infrastructure have not been well studied. We tackle the security of disaggregated multi-FPGA systems by developing a new trusted execution environment (TEE), namely DF-TEE, which for the first time extends the capability of the traditional CPU TEEs to disaggregated FPGA accelerators. DF-TEE employs a secure isolation path to connect all the components in the CPU and multi-FPGA system based on the established mutual trust in the heterogeneous environment, as well as security-aware slicing and deployment of the sensitive computations. We evaluate DF-TEE on a real hardware implementation of disaggregated multi-FPGA system, which justifies its security with acceptable timing and resource overhead.
Development of a Free Fall Drone for Firefighting Applications

Forest fires affect directly the ecological system and cause the destruction of thousands of hectares as well as the loss of houses, properties, and agricultural land. In this paper, the design and development of a free-fall precision aerial delivery system for firefighting applications is presented. The developed free fall drone can be thrown from aircrafts, blimps, or quadcopters and then directs itself autonomously to reach the desired goal. The drone is to be used in wildfire firefighting operations to deliver retardant mixtures, extinguisher solutions, or medical equipment. A special navigation algorithm based on image processing and relative positioning is used to correct the drone path, with control surfaces similar to aircraft canards used as the system actuators. A small parachute is applied to control the falling speed of the drone and ensure free fall condition. Simulation results in MATLAB/Simulink environment show acceptable performance of PID controllers used with the drone. Experimental tests show promising results for the use of the free fall drone in firefighting missions.
A Continuous and Closed-Form Trans-Capacitance Model for Double-Gate Junctionless Transistors

In this study, we present an analytical and closed-form trans-capacitance model for short-channel double-gate junctionless transistors (DG JLTs), applicable across all working regions. The analytical model is derived by building upon a previously developed continuous and analytical drain current (I-V) model from our earlier work. By utilizing the Ward-Dutton charge partition method, we deduce the expressions for terminal charge and trans-capacitance. The validity and accuracy of our proposed model are subsequently verified through TCAD numerical simulations.
NOTES AND CORRESPONDENCE Trends in the North Atlantic Oscillation-Northern Hemisphere Annular Mode during the Twentieth Century*

The North Atlantic Oscillation‐Northern Hemisphere annular mode (NAO‐NAM) has exhibited a trend over recent decades toward high index values. It has been argued that this trend is unprecedented in the historical record and that it may be attributable to anthropogenic forcing. This study compares and contrasts wintertime trends during the recent period of rising NAO‐NAM indices with trends earlier in the century when the indices declined. This analysis finds that the spatial patterns of the trends in sea level pressure (SLP) and surface air temperature (SAT) are markedly different in the two periods. The prior SLP trends were large only in the Atlantic sector, whereas the recent trends of the last few decades were more hemispheric in extent. As a result, trends in a more localized NAO index are roughly comparable for those two intervals, but the recent upward trend in the hemispheric NAM index is more prominent than the earlier downward trend.
Low-Complexity Belief-selective Message Passing (BsMP) Detector for SCMA Systems

Sparse code multiple access (SCMA) is an efficient non-orthogonal multiple access (NOMA) technique designed to address the demands of wireless communication, particularly in systems with massive connections. In this paper, a novel belief-selective message passing (BsMP) algorithm is proposed for the SCMA detection. By circumventing the lattice point with relatively small reliability, the BsMP achieves a lower computational complexity compared with the state-of-the-art (SOA) detector. Numerical results show that for a 6-user regular SCMA system, the proposed BsMP achieves the comparable error performance with the SOA detector while saving about 30% computational complexity. Besides, the hardware architecture of BsMP is also developed, demonstrating the feasibility of the hardware implemention for the proposed BsMP detector.
Creativity and mathematical knowledge in the Plato’s Ion

The aim of this historical-philosophical study is to clarify the understanding of creativity according to Plato, to whom is attributed a conception associated with poetic activity and divine inspiration. The main source of this notion is the dialogue Ion, in which the philosopher criticizes rhapsodies and poets for not having a technique. Among some techniques presented in Ion as contrast is the arithmetic technique. Which directs the research to the elucidation of what Plato understood by technique and expands the list of consulted dialogues. The methodology employed is configured as a hybridism between different trends in Mathematics Education, such as studies on creativity, the history of mathematics, and hermeneutics. The conclusion locates Plato’s critique of poetic activity within the framework of Plato’s epistemological program to improve its interpretation.
IMPLICIT IMITATION OF INTONATION CONTOURS IN WORD SHADOWING

Phonetic imitation of a range of segmental and suprasegmental features has been observed across tasks and instructions, suggesting that this process may be spontaneous and implicit. In contrast, imitation of phonetic features of intonation contours may depend largely on the explicitness of the instructions, especially in non-interactive tasks. In the current study, a word shadowing task without explicit instructions to imitate was used to explore the imitation of intonation contours and their phonetic implementation in American English. The analyses indicate imitation of rising contours, their f0 range, and their alignment with the stressed vowel. However, imitation of falling contours was limited to their alignment with the stressed vowel. These results suggest that the shape of intonation contours may affect their imitation, and that a perceptually more salient contour, such as a rise on an isolated word in American English, may lead to greater imitation.
Antarctic vortex dehydration in 2023 as a substantial removal pathway for Hunga Tonga-Hunga Ha’apai water vapour

The January 2022 eruption of Hunga Tonga-Hunga Ha’apai (HTHH) injected a huge amount (˜150 Tg) of water vapour (H 2 O) into the stratosphere, along with small amount of SO 2 . An oﬀ-line 3-D chemical transport model (CTM) successfully reproduces the spread of the injected H 2 O through October 2023 as observed by the Microwave Limb Sounder (MLS). Dehydration in the 2023 Antarctic polar vortex caused the ﬁrst substantial (˜20 Tg) removal of HTHH H 2 O from the stratosphere. The CTM indicates that this process will dominate removal of HTHH H 2 O for the coming years, giving an overall e-folding timescale of 4 years; around 25 Tg of the injected H 2 O is predicted to still remain in the stratosphere by 2030. Following relatively low Antarctic column ozone in midwinter 2023 due to transport eﬀects, additional springtime depletion due to H 2 O-related chemistry was small and maximised at the vortex edge (10 DU in column).
Hluk kompresoru tepelného čerpadla vzduch-voda Noise of the Air-to-Water Heat Pump Compressor

The article focuses on the noise and vibration propagated from air-to-water heat pump, the most commonly installed type of heat pumps, to its surroundings and to the building structures. From a technical point of view, the topic is limited to heat pumps with electrically driven and hermetically sealed scroll compressors, as these are the most commonly installed type of heat pumps of smaller capacities (up to 50 kW). The paper covers the issue of ON/OFF control as well as the issue of inverter heat pumps. Only the heat pumps installed in the exterior of houses or apartment buildings are addressed. Several separate articles will be devoted to the topic due to its wide scope.
Analysis of the chain-mediated effects of nurses’ sense of professional gain and sense of professional mission between psychological resilience and work engagement in 10 general hospitals in Sichuan province

Objective To explore the chain-mediated role of sense of career benefit and sense of career mission in the mechanism of psychological flexibility’s effect on nurses’ work engagement. Methods Adopting the convenience sampling method, 1032 nurses in 10 general hospitals in Sichuan Province were surveyed by questionnaires using the General Information Questionnaire, Sense of Occupational Benefit Scale, Sense of Occupational Mission Scale, Psychological Flexibility Scale, and work engagement Scale in August-October 2022, and the model of the chained-mediated effect was constructed and validated. Results The total psychological resilience score of nurses in 10 general hospitals in Sichuan Province was (91.29 ± 17.38), the total score of sense of occupational benefit was (137.85 ± 21.02), the total score of sense of occupational mission was (40.27 ± 7.37), and the total score of work engagement was (34.99 ± 9.80). The total score of nurses’ work engagement was positively correlated with the total scores of psychological elasticity, sense of professional benefit, and sense of professional mission (all P < 0.05). The direct effect of psychological elasticity on nurses’ work engagement was significant, with an effect value of 0.321; the chain mediation effects of occupational benefit and occupational mission as separate mediators and the chain mediation effects of the two were 0.039, 0.032, and 0.062, respectively. Conclusion Nurses’ work engagement in 10 general hospitals in Sichuan province is at a medium level, and occupational benefit and occupational mission play a significant role in the mechanism of the psychological elasticity’s effects on nurses’ work commitment, and the chain mediation effect of occupational mission in the mechanism of psychological elasticity is established. The chain mediation effect in the mechanism was established. Managers should pay attention to nurses with low psychological elasticity, improve their sense of occupational benefit, and enhance their sense of occupational mission in order to further promote the enhancement of work engagement.
Prevalence of Physical Nicotine Dependence and its Determinants among Tobacco users in the Rural Field Practice Area of a Tertiary Care Hospital in Tamil Nadu, India

Background: Tobacco is the major cause of preventable death globally, which kills one person prematurely every six seconds. In India, around 46.9% of men and women aged 15 years and above use any kind of tobacco, according to NFHS-5. Tobacco use for longer duration with increased frequency is often addictive. Nicotine in tobacco is often associated with dependence, which is recognized as a public health menace and the single most significant factor for premature death. Hence, assessment of nicotine dependence among tobacco users is essential to implement tobacco control measures effectively. To estimate the prevalence of nicotine dependence among tobacco users and to study the factors associated with nicotine dependence among those tobacco users in a rural area of Kancheepuram district, Tamil Nadu. Material and Methods: A community-based descriptive cross-sectional study was conducted among 375 tobacco users aged 18 years and above residing permanently in the rural field practice area of the Rural Health and Training Centre (RHTC) attached to a Tertiary Care Hospital in Tamil Nadu. The study has been conducted for 6 months. A systematic random sampling technique was used to recruit the study participants. Data was collected by conducting personal interviews using a pre-tested semi-structured questionnaire. The data obtained was subjected to statistical analysis using SPSS version 23. Result: About 48.7% of the study participants had high dependence, 25% had moderate dependence, and 26.3% had low physical dependence on nicotine. The duration of tobacco use (P < 0.0000) and age of initiation of tobacco use (mean age was 28 ± 7.1 years) (P < 0.0001) was found as a significant risk indicator for nicotine dependence. Conclusion: The high nicotine dependence (48.7%) among the study participants is quite alarming and warrants more visible and aggressive anti-tobacco campaigns and targeted preventive strategies.
BRIEF COMMUNICATION: Feed value of maize silage in New Zealand - a review

Introduction Maize silage is a major dietary component for dairy cows in the USA and Germany with average feeding rates of 2.7 and 4.1 tDM per cow per year respectively (Table 1). Maize silage usage in NZ has increased over the past two decades. It currently accounts for approximately 6% of feed energy supplied to the national herd, calculated using national herd energy requirements (based on cow numbers and milk processed 2013/14 in NZ (New Zealand Dairy Statistics 2013/14)) and the amount of maize silage harvested (AIMI 2015). It is important to establish maize silage feed quality in NZ to better understand its potential to support pasturebased farms. Published NZ research has measured in-vivo digestibility of maize silage in animal trials (Kirley 1977; Smith 1973); however, the number of trials is limited and they were not performed using standard protocols to allow pooling of data. The aim of this paper was to compare the nutrient composition of overseas and NZ maize silage to determine if overseas in-vivo energy measurements are applicable to local maize silage and to determine how well NZ maize silage kernel is processed.

Statistics education that promotes creativity and criticality in childhood

The objective of this article is to discuss the approach of statistics education in the early years of elementary school, which favors the development of children's creativity and critical thinking through the resolution of real-world problems. It is argued that the teacher has a fundamental role in the education of students regarding methodologies that highlight their protagonism and promote collective and collaborative production of knowledge. The results indicate that the formation of creative and critical thinking is directly linked to a school with democratic principles, where respect for diversity, collaborative work and dialogue are considered in the resolution of real problem situations
SIZE FREQUENCY DISTRIBUTIONS AS A LICHENOMETRIC TECHNIQUE: AN ASSESSMENT

The use of size frequency distributions of lichen populations has, in the past, been recommended as a lichenometric technique. Theoretically, saxicolous lichen populations should be density-dependent with the result that the size frequency distributions of older populations should be best described by a Poisson model. Evidence from Scotland and Norway indicates that the size frequency distributions are extremely variable, ranging from truncated log-normal to Poisson in form. Consequently, the use of the 1-in-1000 thallus, derived from a log-normal model, is not universally applicable as a descriptive index, particularly in the case of older lichen populations.

DO HUMANS CONVERGE PHONETICALLY WHEN TALKING TO A ROBOT?

Phonetic convergence—i.e., adapting one’s speech towards that of an interlocutor—has been shown to occur in human-human conversations as well as human-machine interactions. Here, we investigate the hypothesis that human-to-robot convergence is influenced by the human’s perception of the robot and by the conversation’s topic. We conducted a within-subjects experiment in which 33 participants interacted with two robots differing in their eye gaze behavior—one looked constantly at the participant; the other produced gaze aversions, similarly to a human’s behavior. Additionally, the robot asked questions with increasing intimacy levels. We observed that the speakers tended to converge on F0 to the robots. However, this convergence to the robots was not modulated by how the speakers perceived them or by the topic’s intimacy. Interestingly, speakers produced lower F0 means when talking about more intimate topics. We discuss these findings in terms of current theories of conversational convergence.
Performance Evaluation using Spanning Tree Protocol, Rapid Spanning Tree Protocol, Per-VLAN Spanning Tree, and Multiple Spanning Tree

This paper examines the concepts and practical applications of the spanning tree protocol (STP). It also covers per-VLAN spanning tree (PVST), multiple spanning tree (MST), and rapid STP (RSTP). Moreover, practical scenarios are presented to help the reader understand the concepts and implementations of these protocols. This study analyzes protocols using seven metrics. All protocols have been evaluated using these metrics in both small and big topology scenarios to obtain the best results. In addition, all metrics are mentioned in the introduction chapter, and the way used to apply tests on the metrics is described in the methodology chapter. Based on the experiments, different STPs performance are compared, including STP, RSTP, PVST, and MST. In summary, findings show that STP is easy to use and performs well overall, but it consistently has high latency issues. RSTP is suitable for small networks and has quick convergence, but it cannot handle as much load as STP. PVST performed the best in the experiments, as it demonstrated high scalability and the ability to handle a lot of pressure, although it requires strong hardware. However, MST did not perform as well as expected, as it struggled with delay problems and high jitter. In conclusion, it is recommended to use RSTP for simple networks that require fast convergence with dependable delay and capacity, or STP for networks that require good scaling and bandwidth. PVST is an excellent option for those who can afford high-performance hardware, while MST is suitable for simple networks or those with outdated hardware.
