Indexing-Min–Max Hashing: Relaxing the Security–Performance Tradeoff for Cancelable Fingerprint Templates

Cancelable biometrics is a powerful remedy for information leakage caused by the extensive usage of unprotected biometric data. Current measures usually suffer from deteriorated accuracy, which is known as the security–performance tradeoff. Motivated by these concerns, in this article, a novel cancelable fingerprint approach, i.e., Indexing-Min–Max (IMM) hashing, is proposed to securely transform a fixed-length fingerprint feature vector to a discrete index hashed code. IMM hashing is essentially established upon the min–max hash and further strengthened by the integration of the partial Hadamard transform, which alleviates performance deterioration while maintaining a high security level. Extensive experiments on FVC2002 and FVC2004 fingerprint datasets coupled with comprehensive theoretical analyses demonstrate the favorable accuracy and strong anti-attack resilience of the proposed method. Besides, compared to the unprotected counterpart, the matching precision of the protected templates yields little accuracy loss or even improved performance, which means the security–performance tradeoff is well handled. Furthermore, IMM hashing also meets the unlinkability and revocability requisites of cancelable biometrics.
The biopsychosociotechnical model: a systems-based framework for human-centered health improvement

ABSTRACT The biopsychosocial model is among the most influential frameworks for human-centered health improvement but has faced significant criticism– both conceptual and pragmatic. This paper extends and fundamentally re-structures the biopsychosocial model by combining it with sociotechnical systems theory. The resulting biopsychosociotechnical model addresses key critiques of the biopsychosocial model, providing a more “practical theory” for human-centered health improvement. It depicts the determinants of health as complex adaptive system of systems; includes the the artificial world (technology); and provides a roadmap for systems improvement by: differentiating between “health status” and “health and needs assessment”, [promoting problem framing]; explaining health as an emergent property of the biopsychosociotechnical context [imposing a systems orientation]; focusing on “interventions” vs. “treatments” to modify the biopsychosociotechnical determinants of health, [expanding the solution space]; calling for a participatory design process [supporting systems awareness and goal-orientation]; and including intervention management to support the full lifecycle of health improvement.

Research on the Recognition Algorithm of Basketball Technical Action Based on BP Neural System

Vision-based intelligent human action recognition is the most challenging direction in the field of computer vision in recent years. It detects human actions in video sequences, extracts action features and learns action features, and then recognizes human actions in videos. This paper is based on BP neural network’s basketball technique action recognition and experimental verification. First, design a basketball technique action recognition method based on BP neural network, analyze basketball actions, collect relevant test data, and divide the methods of basketball action recognition. Finally, analyze the action characteristics and waveform conditions of the upper- and lower-limb movements of the basketball action and analyze the key basketball action recognition data. The designed classification method realizes the effective recognition of basketball actions; then, the basketball recognition method used in this article is experimentally verified, and the feasibility and effectiveness of the recognition method selected in this article are verified by recognizing basketball technical actions, and the experimental results are carried out. Compared with other related studies, this method proposes a division of unit actions to complete the cycle division of basketball actions. The division results do not include the overlap of other actions, avoiding repeated calculations of actions and greatly reducing the amount of calculation of the system. In addition, the method for the recognition of basketball movement includes the separate recognition of upper- and lower-limb movements, comprehensive consideration of arm and leg movements, and a more comprehensive and accurate analysis of basketball movements.
Overcoming CubeSat downlink limits with vitamin: A new variable coded modulation protocol

Many space missions, including low earth orbit CubeSats, communicate in a highly dynamic environment because of variations in geometry, weather, and interference. At the same time, most missions communicate using fixed channel codes, modulations, and symbol rates, resulting in a constant data rate that does not adapt to the dynamic conditions. When conditions are good, the fixed date rate can be far below the theoretical maximum, called the Shannon limit; when conditions are bad, the fixed data rate may not work at all. To move beyond these fixed communications and achieve higher total data volume from emerging high-tech instruments, this thesis investigates the use of error correcting codes and different modulations. Variable coded modulation (VCM) takes advantage of the dynamic link by transmitting more information when the signal-to-noise ratio (SNR) is high. Likewise, VCM can throttle down the information rate when SNR is low without having to stop all communications. VCM outperforms fixed communications which can only operate at a fixed information rate as long as a certain signal threshold is met. This thesis presents a new VCM protocol and tests its performance in both software and hardware simulations. The protocol is geared towards CubeSat downlinks as complexity is focused in the receiver, while the transmission operations are kept simple. This thesis explores bin-packing as a way to optimize the selection of VCM modes based on expected SNR levels over time. Working end-to-end simulations were created using MATLAB and LabVIEW, while the hardware simulations were done with software defined radios. Results show that a CubeSat using VCM communications will deliver twice the data throughput of a fixed communications system.
The Burden of Likely Rubella Infection among Healthy Pregnant Women in Abakaliki, Ebonyi State, Nigeria

The first 140 days of pregnancy are critical as regards rubella virus infection because of the likelihood of a poor pregnancy outcome. This study was undertaken to investigate the likelihood of exposure to poor pregnancy outcomes due to seroprevalence of rubella among selected pregnant women attending Mile Four Hospital, Abakaliki, Ebonyi State, Nigeria. The seroprevalence of rubella immunoglobulin M (IgM) antibodies was investigated among pregnant women. A total of 187 sera samples collected from the women were screened for rubella virus IgM antibody using the enzyme-linked immunosorbent assay (ELISA). The results obtained were analyzed using SPSS. The chi square test was performed at a P value of 0.05 significance and at a 95% confidence interval. Of the 187 pregnant women, 35 (18.72%) were positive for the rubella virus. Pregnant women within 26–30 years of age had the highest prevalence (26.15%), while those aged 35–40 years had the least prevalence. Married women had the highest prevalence (20.0%), followed by singles (16.67%) and widows (15.38%), while divorced pregnant women recorded the least prevalence (9.20%). Pregnant women with no formal education were more predisposed to rubella virus (22.22%) infection compared to their educated counterparts. Occupationally, full-time housewives had the highest prevalence (24.26%). The infection rates seemed to wane as pregnancy advanced. The first trimester had the highest prevalence (21.88%), followed by the second trimester (18.84%) and the third trimester (17.44%). Pregnant women living in urban areas had higher IgM seroprevalence (20.18%) than those in rural areas (16.67%). Furthermore, grand multigravidas were more infected (22.73%) than primigravidas (14.52%) and multigravidas (20.39%). The seroprevalence of rubella in this study was high, and it calls for general surveillance and mass immunization of children and females of childbearing age in the area to help reduce the incidence of congenital rubella syndrome.
Support Father Engagement: What Can We Learn From Fathers?

Fathers play a unique and important role in children’s lives. However, gendered attitudes and practices with families have precluded their full engagement in children’s education and development. Based on the collective effort of a local fatherhood coalition, the purpose of this community-based study was to explore how fathers view themselves as involved in children’s lives and their perceived barriers to involvement in order to initiate change in local schools and community. Twenty-three fathers from ethnically and socioeconomically diverse backgrounds participated in interviews and focus groups to describe their definitions of father involvement, strengths as fathers, and needs. A collaborative, qualitative analysis of data led to the identification of four themes that framed the experiences of fathers and their needs. Mothers played a powerful role in promoting and prohibiting fathers’ involvement; technology provided opportunities to connect but also interfered with attachment efforts; fathers in more privileged positions were able to focus on attachment rather than merely providing; and school engagement was rarely mentioned with a focus on extra-curricular involvement. We discuss the influence of paternal characteristics and situational factors in how these themes inform the lives of fathers and the complex nature of fatherhood. Implications for schools and communities are offered in hopes to disrupt current practices and design more inclusive and equitable approaches to including fathers in family engagement efforts.
A Flash Frequency Tuning Technique for SC‑Based mm Wave VCOs

This paper presents a flash frequency tuning technique for switched‑capacitor‑based, voltage‑controlled oscillators operating at mm wave frequencies. The proposed strategy exploits a capacitor array and a small varactor for coarse and fine tuning, respectively, which are simultaneously operated thanks to a flash A/D‑based control circuit. This avoids additional delay in the frequency calibration, thus enabling very fast-frequency locking operation. The VCO was fabricated in a 28 nm FD-SOI CMOS technology and provides an oscillation frequency around 39 GHz with an overall tuning range of 3.3 GHz. The circuit dissipates 8.4 mW from a power supply as low as 0.7 V, while occupying a silicon area of 210 µm × 150 µm.
Expression of heat shock protein D1 is up-regulated in canine mammary tumors

Background- Mammary tumors are frequently seen in female dogs. Conventionally, these tumors are diagnosed by histopathology. Differentially expressed biomarkers could aid in non-invasive diagnosis of canine mammary tumors but their number is scanty. The present investigation focuses on assessing HSPD1 as a diagnostic biomarker of canine mammary tumors. Methods and results- Expression of HSPD1 transcript was analyzed by SYBR green based real time PCR (qRT-PCR). Gene encoding immuno-dominant region of HSPD1 was cloned using the expression vector pPROEX-HTa and expressed in a prokaryotic system. Upon purification by affinity chromatography, a 60KDa recombinant protein was obtained which was confirmed by Western blotting. Hyperimmune serum was raised against the rHSPD1 in mice and immunohistochemistry was standardized to assess expression of this protein in various histotypes of canine mammary tumors. Elevated level of HSPD1 mRNA expression (4.92 ± 0.65folds) was observed in canine mammary tumors as compared to the healthy mammary tissue. Further, HSPD1 protein expression in 80% of healthy tissues showed mild immunoreactivity whereas, moderate to high expression of HSPD1 was seen in 80% CMT tissue samples. Conclusions- The findings suggest that HSPD1 could act as molecular marker for the diagnosis of mammary tumors in canines and also to assess the response to these subjects to treatment.
Temporal Interference (TI) Stimulation Boosts Functional Connectivity in Human Motor Cortex: A Comparison Study with Transcranial Direct Current Stimulation (tDCS)

Temporal interference (TI) could stimulate deep motor cortex and induce movement without affecting the overlying cortex in previous mouse studies. However, there is still lack of evidence on potential TI effects in human studies. To fill this gap, we collected resting-state functional magnetic resonance imaging data on 40 healthy young participants both before and during TI stimulation on the left primary motor cortex (M1). We also chose a widely used simulation approach (tDCS) as a baseline condition. In the stimulation session, participants were randomly allocated to 2 mA TI or tDCS for 20 minutes. We used a seed-based whole brain correlation analysis method to quantify the strength of functional connectivity among different brain regions. Our results showed that both TI and tDCS significantly boosted functional connection strength between M1 and secondary motor cortex (premotor cortex and supplementary motor cortex). This is the first time to demonstrate substantial stimulation effect of TI in the human brain.
The Efficient Implementation of Hybrid Power Plants in Indonesia

The energy crisis is a serious issue that all countries around the world are dealing with, particularly the energy sources used to generate electricity. There are numerous alternative energy sources available in nature, such as solar energy, wind energy, and so on. Wind and solar energy as hybrid energy sources are thought to be promising in electric generation technology. Hybrid Power Plants can also be used to address the issue of limited electrical energy supply in Indonesia's remote areas. The purpose of this study is to describe the effectiveness of the hybrid power plants implementation in Indonesia. The study was conducted using the narrative literature review method. It can be inferred that the purpose of developing this hybrid technology, among others, is to obtain more efficient electrical energy generation by combining the advantages of two or more types of power generation systems that work in an integrated manner as a compact system. The produced electric energy can be stored in the battery. In terms of use, the produced direct current (DC) is converted into alternating current (AC) using the inverter system prior to distribution to consumers. Therefore, this hybrid power plant is suitable to be implemented in Indonesia.
High temperature erosive behaviour of plasma sprayed NiCrAlY/B4C/Cenosphere coating on MDN 321 turbine steel

ABSTRACT The present work is concentrated on the erosive behaviour of NiCrAlY/B4C/Cenosphere composite coating at high temperatures. The coating was deposited on MDN 321 steel used in turbine blades by plasma spray coating technique. The erosion tests were carried out at impingement angles of 60° and 90° with temperature at 600°C in both cases. The coatings and worn samples were characterised by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Al2O3 particles of 150 microns were used as the erodents with a velocity of 30 m s−1. The erosive wear resistance for the impingement angle of 60° was found to be higher compared to 90°. The major failure of the material is shown by the brittle nature of the material removal. This is also reflected by the higher particles size found around the eroded area and higher surface roughness values of Ra and Rz.
Genome-wide identification and characterization of the Dof gene family in Prunus sibirica

Prunus sibirica (Siberian apricot) is a species of the family Rosaceae, section Armeniaca (Lam.) Koc, which has enormous potential for oil and food raw materials. DNA binding with one finger ( Dof ) transcription factors play major roles in plant biological processes. However, the evolutionary and functional information of the Dofs in P. sibirica remain unclear. Here, we conducted a genome-wide screening and characterization of the Dofs in P. sibirica, and 24 putative PsDofs were identified, which were distributed across all eight chromosomes. Phylogenetic analysis showed that PsDofs were divided into four major groups (A, B, C, and D). The gene structure and conserved motifs of PsDofs were also predicted. The expression profiles of PsDofs exhibited different expression patterns in flower buds, flowers, leaves, fruits, and kernels. This study provides an important foundation for better understand the evolution and function of PsDofs s.

Supplementary material to "Using geochemistry to understand the sources and mean transit times of stream water in an intermittent river system: the upper Wimmera River, southeast Australia"

Abstract. Determining the mean transit times (MTTs) and water sources in catchments at different flow conditions helps better understand river functioning, manage riverine system health and water resources, and discern the responses to climate change and global water stress. Despite being common in a range of environments, understanding of MTTs and variable water sources in intermittent streams remain incomplete compared to perennial streams. Major ion geochemistry, stable isotopes, 14C, 3H and were used in this study to identify water sources and MTTs of a periodically-intermittent river from southeast Australia at different flow conditions, including zero-flow periods. The disconnected pool waters during the zero-flow period in the summer months of 2019 had 3H activities of 0.64 to 3.29 TU. These and the variations in total dissolved solids and stable isotopes imply that these pools contained a mixture of groundwater and younger evaporated stream water. 3H activities during the high-flow period in July 2019 were 1.85 to 3.00 TU, yielding MTTs of up to 17 years. The 3H activities at moderate and low-flow conditions in September and November 2019 ranged from 2.26 to 2.88 TU, implying MTTs of 1.6 to 7.8 years. Regional groundwater near the Wimmera River has 3H activities of < 0.02 to 0.45 TU and 14C activities of 57 to 103 pMC and is not recharged by the river at high flows. The Wimmera River and other intermittent streams in southeast Australia are sustained by smaller volumes of younger catchment waters than comparable perennials streams, indicating that near-river stores have significant impacts on maintaining streamflow during low-flow periods than older deeper regional groundwater. These smaller reservoirs result in the intermittent streams being more susceptible to changes of climate and streamflow and necessitate protection of near-river corridors to maintain the health of the riverine systems.
A comprehensive review on Bi2Te3‐based thin films: Thermoelectrics and beyond

Bi2Te3‐based materials are not only the most important and widely used room temperature thermoelectric (TE) materials but are also canonical examples of topological insulators in which the topological surface states are protected by the time‐reversal symmetry. High‐performance thin films based on Bi2Te3 have attracted worldwide attention during the past two decades due primarily to their outstanding TE performance as highly efficient TE coolers and as miniature and flexible TE power generators for a variety of electronic devices. Moreover, intriguing topological phenomena, such as the quantum anomalous Hall effect and topological superconductivity discovered in Bi2Te3‐based thin films and heterostructures, have shaped research directions in the field of condensed matter physics. In Bi2Te3‐based films and heterostructures, delicate control of the carrier transport, film composition, and microstructure are prerequisites for successful device operations as well as for experimental verification of exotic topological phenomena. This review summarizes the recent progress made in atomic defect engineering, carrier tuning, and band engineering down to a nanoscale regime and how it relates to the growth and fabrication of high‐quality Bi2Te3‐based films. The review also briefly discusses the physical insight into the exciting field of topological phenomena that were so dramatically realized in Bi2Te3‐ and Bi2Se3‐based structures. It is expected that Bi2Te3‐based thin films and heterostructures will play an ever more prominent role as flexible TE devices collecting and converting low‐level (body) heat into electricity for numerous electronic applications. It is also likely that such films will continue to be a remarkable platform for the realization of novel topological phenomena.
