Retrieval Transformation: Dynamic Searchable Symmetric Encryption With Strong Security

Extending the single-user searchable symmetric encryption (SSE) immediately to the multiuser scenario is not straightforward. In the multiuser scenario, recipients cannot safely achieve multisearchable computing without using a third party or specified users, which diminishes the application's utility. Moreover, there are two issues related to pattern privacy and file updating: One is that the majority of extant SSEs only emphasize the privacy of a partial pattern (one of the search/access/size patterns), resulting in information leakage. The second issue is that, with the exponential expansion of the number of files, it is unclear how to achieve unrestricted index capacity management while efficiently updating the encrypted index. To overcome the aforementioned issues, we offer a general dynamic named <inline-formula><tex-math notation="LaTeX">$G$</tex-math></inline-formula>-<inline-formula><tex-math notation="LaTeX">$DSSE$</tex-math></inline-formula>, that is blended with the pseudorandom function and the integer vector homomorphic encryption. Combining <inline-formula><tex-math notation="LaTeX">$k$</tex-math></inline-formula>-anonymity and delayed write-back techniques, <inline-formula><tex-math notation="LaTeX">$G$</tex-math></inline-formula>-<inline-formula><tex-math notation="LaTeX">$DSSE$</tex-math></inline-formula> can realize multisearchable computing without relying on a third party while simultaneously guaranteeing multiple patterns and greater forward/backward privacies. The combination of <inline-formula><tex-math notation="LaTeX">$k$</tex-math></inline-formula>-anonymity and delayed write-back solves the unnecessary waste of communication overhead and the problem of pattern leakage in extreme cases. <inline-formula><tex-math notation="LaTeX">$G$</tex-math></inline-formula>-<inline-formula><tex-math notation="LaTeX">$DSSE$</tex-math></inline-formula> achieves noninteractive update, even batch update, and nonrestrictive index capacity management in the encrypted index. Meanwhile, it can be expanded flexibly to ensure the precision and integrity of search results.
18.3: Color Breakup Reduction by 180Hz Stencil‐FSC Method in Large‐Sized Color Filter‐Less LCD‐TVs

We proposed the “180Hz Stencil‐FSC” method to suppress color break‐up (CBU) infield‐sequential‐color (FSC) LCDs. Applying local color‐backlight‐dimming technology to FSC‐ LCDs, a “green‐based multi‐color” field‐image was generated to show most image luminance at the first field and effectively suppressed CBU even compared to field‐rate increasing methods. In addition, for further hardware implementation, the number of backlight divisions of 32 ×24 was optimized while considering CBU suppression and image fidelity.
Barriers to Corporate Sustainability in the U.S.

Sustainability is critical to the future success of businesses; those that do not implement sustainability initiatives may lose customers, investors, and/or profits. This study examines barriers to corporate sustainability, measured through the four dimensions of the Prism of Sustainability (environmental, social, economic, and institutional), a framework of sustainability not commonly used in business research. An online survey of sustainability managers from a variety of industries in the United States distributed in the spring of 2021 yielded a total of 361 responses. Results reveal that lack of leadership and lack of governance were the most predominant barriers to corporate sustainability. Surprisingly, the most frequently cited barrier in the literature—resources—was not identified as a significant barrier for U.S. companies. The impact of the pandemic was also qualitatively explored to see if such constraints might have a nuanced effect on corporate sustainability efforts. This research expands the contexts in which the Prism of Sustainability is applied in business studies, highlighting it as a means to assess corporate sustainability. Results provide important managerial implications, highlighting the importance of measures to govern the organization’s sustainability effort and the critical role leadership plays. Sustainable management is a necessity for business, and therefore, addressing barriers to achieving it will be imperative for companies’ futures.
Seismic Modeling of Fluvial-Estuarine Deposits in the Athabasca Oil Sands Using Ray-Tracing Techniques, Steepbank River Area, Northeastern Alberta

ABSTRACT Most of the bitumen ressources in the Athabasca oil sands area are contained in fluvial and estuarine channel deposits of the Lower Cretaceous McMurray Formation. Stratigraphic sections were measured along a 5 km stretch of the Steepbank River, north of Fort McMurray, near the Suncor Steepbank Mine. We have identified at least four channel complexes based on stratal bounding surfaces, arrangement of exposed lithofacies, and consistent paleoflow patterns. The lower part of each channel complex contains medium to large-scale, trough crossbedded sandstone, exhibiting high porosity and permeability. These sandstones were deposited in channel axes and are the highest-grade bitumen deposits in the study area. Overlying inclined beds (sandy or muddy inclined heterolithic stratification) downlap on the lower sandy beds and were deposited in estuarine point bars, but the permeability and bitumen saturation of these strata are considerably lower. Nearby wells contain cored and logged intervals that are similar to exposed outcrops in the riverbank. For the outcrop sections, artificial sonic logs were constructed by comparison with sonic curves from these nearby wells, but the curves were modified to reflect differences in thickness and mud content at the exposure. Three structural-stratigraphic cross-sections and ray-tracing techniques were used to construct seismic models. These models compare favourably with four high-quality, industry-acquired seismic lines from the Clarke Creek ExxonMobil lease area, about 20 km southeast of the Steepbank River outcrops. The deposits at Steepbank are thus similar in scale and geometry to those in the Clarke Creek area. The Clarke Creek channel complexes are very well imaged on the seismic profiles, and our seismic modeling indicates that high-resolution seismic data are necessary to image these channels. 1 Present Address: Alberta Energy and Utilities Board, 640 - 5 Avenue SW, Calgary, AB T2P 3G4 End_Page 178------------------------
Benefits of artificial reefs in Altinoluk (Northern Aegean), Turkey: Assessment of potential users' opinions via fuzzy pair wise comparison approach Altinoluk'da (Kuzey Ege) yapay resiflerin faydalari: Bulanik eşli karşilaştirma yaklaşimi ile potansiyel kullanicilarin görüşlerinin değerlendirilmesi

Artificial Reefs (ARs) are used in many coastal countries, mainly for fisheries management purposes. The aim of this study is to assess user's benefits from artificial reefs. Fuzzy Pair-Wise Comparison (FC) Method was used to introduce users' opinions on main potential benefits of ARs in Altinoluk (Edremit Bay, North Aegean Coast of Turkey). Three benefits of artificial reefs including social, biological and economic were represented to commercial fishermen, recreational fishermen and local residents. Then, the weights of the benefits were calculated by pair-wise comparisons in the FC Method. Survey data was obtained by face-to-face interviews using questionnaire forms with potential users including commercial fishermen, recreational fishermen and local residents. According to the results gathered from the FC Method, commercial fishermen ranked economic benefits of artificial reefs as highest whereas recreational fishermen and local residents were agreed on biological benefits. In conclusion, ARs deployments without measuring perception of users may not meet the objectives. Studies aiming to measure the perception of AR related groups guide decision makers during the process of planning.
Entanglement Degradation in Two Interacting Qubits Coupled to Dephasing Environments

One of the main obstacles toward building efficient quantum computing systems is decoherence, where the inevitable interaction between the qubits and the surrounding environment leads to a vanishing entanglement. We consider a system of two interacting asymmetric two-level atoms (qubits) in the presence of pure and correlated dephasing environments. We study the dynamics of entanglement while varying the interaction strength between the two qubits, their relative frequencies, and their coupling strength to the environment starting from different initial states of practical interest. The impact of the asymmetry of the two qubits, reflected in their different frequencies and coupling strengths to the environment, varies significantly depending on the initial state of the system and its degree of anisotropy. For an initial disentangled, or a Werner, state, as the difference between the frequencies increases, the entanglement decay rate increases, with more persistence at the higher degrees of anisotropy in the former state. However, for an initial anti-correlated Bell state, the entanglement decays more rapidly in the symmetric case compared with the asymmetric one. The difference in the coupling strengths of the two qubits to the pure (uncorrelated) dephasing environment leads to higher entanglement decay in the different initial state cases, though the rate varies depending on the degree of anisotropy and the initial state. Interestingly, the correlated dephasing environment, within a certain range, was found to enhance the entanglement dynamics starting from certain initial states, such as the disentangled, anti-correlated Bell, and Werner, whereas it exhibits a decaying effect in other cases such as the initial correlated Bell state.
Extracellular Vesicles in Sepsis: Pathogenic Roles, Organ Damage, and Therapeutic Implications

Despite significant advances in anti-infective treatment and organ function support technology in recent years, the mortality rate of sepsis remains high. In addition to the high costs of sepsis treatment, the increasing consumption of medical resources also aggravates economic pressure and social burden. Extracellular vesicles (EVs) are membrane vesicles released from different types of activated or apoptotic cells to mediate intercellular communication, which can be detected in both human and animal body fluids. A growing body of researches suggest that EVs play an important role in the pathogenesis of sepsis. In this review, we summarize the predominant roles of EVs in various pathological processes during sepsis and its related organ dysfunction.
Medical Implications of “Aggressive Prayer”: A Silent Fright among African Christian Patrons in Ghana

The burgeoning trend of “aggressive prayer” in African Christianity has attracted diverse criticism, as to whether or not it is practised responsibly. This work focused on the medical implications of the phenomenon of “aggressive prayer” on African Christian patrons. The study indicates that inasmuch as there could be some health benefits if this phenomenon is considered as a form of aerobics, there is a very high index proclivity of the spread of infectious and respiratory diseases and possible worsening of an already existing disease conditions of patients who participate during “aggressive prayer” sessions.
Toxicity evaluation of zinc oxide nanoparticles green synthesized using papaya extract in zebrafish

In green synthesis of zinc oxide nanoparticles (ZnO NPs), the use of papaya extract as a capping and reducing agent shows promise for potential applications of these particles in biomedicine. However, toxicity evaluation is necessary to ensure the safety of humans and the environment. The zebrafish model is used to assess toxicity with embryo developmental observation as it is a rapid, simple method for screening of toxicity. The objective of the present study was to assess the toxicological characteristics of ZnO NPs produced from papaya extract using a zebrafish model. The preparation of plant extracts from papaya using two solvents (water and methanol) and characterization of bioactive compounds in the extracts were reported. ZnO NPs were synthesized from both plant extracts and characterized with scanning electron microscopy, X-ray diffraction and Fourier transform infrared spectroscopy. Toxicity evaluation was conducted on zebrafish embryos for 96 h. ZnO NPs synthesized from aqueous and methanol extracts had mean crystallite diameters of 13 and 12 nm, respectively. Mortality, hatching rate and malformation of zebrafish embryos were assessed at different concentrations of ZnO NPs. Both NPs showed high mortality rates at high concentrations, with 100 (aqueous) and 20 mg/l (methanol extract) being lethal for all embryos. Concentrations <10 mg/l for both synthesized ZnO NPs had similar results to the negative control, indicating a safe dosage for embryos. The hatching rate and malformation were also affected, with higher concentrations of NPs causing a delayed hatching rate and malformation in pericardial and yolk sac edema. Whole embryo mRNA expression of immune-associated genes, including IL-1 and -10 and TNF-α, was upregulated following lethal concentration 50 (LC50) ZnO NP exposure. ZnO NPs synthesized from papaya extract (both in aqueous and methanol environments) had a dose- and time-dependent embryonic toxicity effect. Hence, the present study demonstrated initial toxicity screening of ZnO NPs synthesized from plant extract.
Flow resistance in steep streams: An experimental study

Frequently, an assessment of the mean water velocity in a stream is necessary to estimate the discharge associated with a particular flow depth or, conversely, the mean depth associated with a particular discharge. In the absence of a direct measurement of flow velocity, a flow resistance approach, which establishes the relation between depth and velocity, can be applied. Two approaches have been used in the past: traditional approaches based on the use of a resistance coefficient (e.g., Darcy‐Weisbach) or dimensionless hydraulic geometry approaches. To examine if one approach is more appropriate for steep streams, data from 31 flume experiments conducted to examine flow resistance in self‐formed cascade channels were analyzed. A dimensionless hydraulic geometry approach developed using at‐a‐station data to characterize the q* exponent and between‐site data to characterize the exponent on the channel slope term was more accurate than more traditional approaches. The developed relation was similar to the established rational relation (v α g0.2q0.6s−0.4S0.2), suggesting that the rational relation has merit. The approach does not utilize a flow partitioning approach since, in steep streams with small relative depths, the grains themselves generate form and spill resistance. The observation that a single dimensionless hydraulic geometry flow resistance relation can describe measurements across a range of grain sizes and bed slopes (3–21%) suggests that steep streams may follow a single scaling relation similar to the regime equations associated with lowland rivers.
Sub-Terahertz Metallic Multibeam Antenna Based on a Sliding Aperture Technique

This article presents a fully metallic waveguide- based multibeam antenna operating at the band from 410 to 480 GHz. The multibeam function is achieved based on the sliding aperture technique. The antenna is composed of a beamforming network based on self-compensating waveguide phase shifters, a parallel plate waveguide (PPW), and seven waveguide feeders. Each self-compensating phase shifter is realized by equal-length widened-and-grooved waveguide sections with a low-dispersion phase delay, which ensures a wide operating band. The design method of the beamforming network and the phase shifter is detailed. A prototype is manufactured using high-precision computer numerical control (CNC) machining and experimentally verified on S-parameters and radiation performances. The measured results show good impedance matching at all ports and low mutual couplings between them. The achieved beam scanning ranges within the band from 410 to 480 GHz are wider than ±30° with scan losses lower than 2.5 dB. The excellent agreement between the measured and simulated results verifies the design approach and the manufacturing technique. This work demonstrates a practical solution to sub-terahertz (THz) passive multibeam antenna with a robust and reliable metallic structure.
Central composite disigns for optimization of the energy factor in 3D printing

This study proposes an optimization strategy to analyze the trade-off between the conflicting objectives of minimizing energy use in 3D printing by fused deposition modeling. The motivation for this work is the need to optimize natural resources, finite in nature, in a more competitive industrial reality and increasingly focused on sustainability, another important point is that energy savings generate improvement in consumption raising organizational profit. The methodologies used were a brief review of the literature and response surface methodology in a CCD experiment. The modeling of the specimen took place through the CAD Fusion 360 software, its development began with the creation of a rectangular 2D sketch, obeying the parameters of 80 mm in its length and 10 mm in width, an Ender 3 printer, yellow PLA, was used following the guidelines set out in ISO 178. Objective of the research is to optimize the manufacturing process using fused deposition modeling, reducing energy consumption (kwh). A complete factorial design was used , as factors: the printing speed (X1), the printing density (X2), layer height (X3) and the layer width (X4), as a response of the experiment were adopted for the manufacturing process, energy (Y). The residue normality tests were performed, with a p-value of 0.170 > 0.05, showing that the data are normal, the VIF below 10 and R-sq (adj) is above 87.16%, the equation has the validated model.
DASMcC: Data Augmented SMOTE Multi-Class Classifier for Prediction of Cardiovascular Diseases Using Time Series Features

One of the leading causes of mortality worldwide is cardiovascular disease (CVD). Electrocardiography (ECG) is a noninvasive and cost-effective tool to diagnose the heart’s health. This study presents a multi-class classifier for the prediction of four different types of Cardiovascular Diseases, i.e., Myocardial Infarction, Hypertrophy, Conduction Disturbances, and ST-T abnormality using 12-lead ECG. There are four key steps involved in the presented work: data preprocessing, feature extraction, data preparation, and augmentation, and modelling for multi-class CVD classification. The sixteen-time domain augmented features are used to train the classifier. The work is divided into three parts: extracting the features from raw 12-lead ECG signals, data preparation and augmentation, and training, testing, and validating the classifier. A comparative study of the performance of five different classifiers (i.e., Random Forest (RF), K Nearest Neighbors (KNN), Gradient Boost, Adda Boost, and XG Boost has also been presented. Accuracy, precision, recall, and F1 scores are used for performance evaluation. Further, the Receiver Operating Curve (ROC) is traced, and the Area Under the Curve (AUC) is calculated to ensure the unbiased performance of the classifier. The application of the proposed classifier in the Smart Healthcare framework has also been discussed.
Deep ocean inertia‐gravity waves simulated in a high‐resolution global coupled atmosphere–ocean GCM

In order to investigate the deep ocean inertia‐gravity waves, a high‐resolution global coupled atmosphere–ocean simulation is carried out with a coupling interval of 20 minutes. Large (∼10−3 m s−1) root‐mean‐square variability of vertical velocity is found in middepths (2000–4000 m), which is not reported in previous studies using realistic ocean simulations. Horizontal distribution of the large variability roughly corresponds to the wintertime atmospheric storm tracks and is stretched equatorward due to β‐dispersion in open ocean with some “shadow regions” behind the obstacles. Frequency spectrum of vertical velocity has strong peaks at around f and 2f (f is the local inertial period) in midlatitudes, and has additional peak at around (3/2)f or 3f at some points. These results suggest necessity of re‐evaluation of wind‐induced near‐inertial energy with high‐frequency atmospheric forcing.
Testing Block Probes for Wall Shear Stress Measurement in Water Flows

The authors developed and tested two types of sublayer pressure probe or blocks, to indirectly measure the average modulus and direction of the wall parallel component of the shear stress tensor, usually referred to as wall shear stress, or boundary shear, in water flows. The local shear stress has been investigated by means of a Preston tube for different Reynolds numbers, in a smooth rectangular section duct. The observed data have been used to calibrate the blocks. The blocks’ design is a direct outcome of the Dexter yaw meter, developed to function in an air flow. The observed pressure field associated with a given shear stress is compared to its theoretical counterpart, based on the assumption that the velocity profile satisfies a two-dimensional law of the wall, for smooth boundary.
Recreational Demand at Lakes and Reservoirs

Recreational benefits from water resources projects and esthetic losses due to poor river quality in urban areas are increasingly being incorporated in metropolitan planning studies. A review of some of the factors influencing the demand for outdoor water-oriented recreation is appropriate prior to describing specific methods for estimating benefits. Major factors influencing the demand for such recreation are many, varied, and interrelated. Some of them relate to the user, others to the recreational area, while others describe the relationship between the user and the recreational area. Some of these factors are: (1) travel distance; (2) travel time; (3) population and population distribution; (4) socioeconomic characteristics of the population; (5) the quality of the recreational experience; and (6) the availability of other recreational facilities. Attempting to find a method to estimate recreational demand that incorporates all factors is a formidable task. Two general procedures have been developed: the demand curve method and the visitor or day user method. The fundamental assumption in both is the correlation between use of a recreational area and willingness to pay.
Restore the shore: online STEM engagement impacts on youths’ conceptualizations of living shorelines and connection to water

Abstract Virtual reality (VR) and electronic field trips (EFT) can introduce youth to natural environments, climate change mitigation strategies, and related STEM careers. We developed a VR and EFT outreach program featuring scientists working on living shorelines for coastal restoration as a response to sea-level rise and examined the program’s impacts on youth through survey and arts-based methods. We found that: a) VR and EFTs proved to be effective for increasing participants’ connection to water, shoreline conservation, and STEM careers and b) arts-based methods can be used to examine participants’ sense of place but could be strengthened to emphasize human-environment connection.
