Cyber4Drone: A Systematic Review of Cyber Security and Forensics in Next-Generation Drones

Cyber Security and forensics for Unmanned Aerial Vehicles (UAVs) pose unique requirements, solutions, and challenges. As UAVs become increasingly prevalent for legitimate and illegal use, ensuring their security and data integrity is important. Solutions have been developed to tackle these security requirements. Drone forensics enables the investigation of security incidents involving UAVs, aiding in identifying attackers or determining the cause of accidents. However, challenges persist in the domain of UAV security and forensics. This paper surveys drone threat models, security, and privacy aspects. In particular, we present the taxonomy of drone forensics for investigating drone systems and talk about relevant artifacts, tools, and benchmark datasets. While solutions exist, challenges such as evolving technology and complex operational environments must be addressed through collaboration, updated protocols, and regulatory frameworks to ensure drones’ secure and reliable operation. Furthermore, we also point out the field’s difficulties and potential future directions.
Deformation of L∞-Algebras

In this paper, deformations of L1-algebras are defined in such a way that the bases of deformations are L1-algebras, as well. A universal and a semiuniversal deformation is constructed for L1-algebras, whose cotangent complex admits a splitting. The paper also contains an explicit construction of a minimal L1-structure on the homology H of a differential graded Lie algebra L and of an L1-quasi-isomorphism between H and L.
Dilemma of employment discrimination against American LGBT employees and its judicial response from the perspective of China

ABSTRACT The United States is an unavoidable setting for Chinese academics researching China’s employment anti-discrimination laws. In the U.S. the LGBT employee population has experienced significant employment discrimination and persistent obstacles in pursuing equal employment opportunity rights. The U.S. Supreme Court has broadened the definition of sex discrimination in three recent consolidated cases based on the opinion that discrimination because of sexual orientation and gender identity is essentially sex discrimination, granting LGBT employees equal employment opportunity rights under groundbreaking case law. This is in line with the rationale of the employment anti-discrimination laws, which forbid employers from discriminating against employees based on their immutable and uncontrollable characteristics, and offers extraterritorial experience to improve employment anti-discrimination laws in other countries, such as China.
A techinque for developing the ratio of supercell to non-supercell thunderstorms

A thunderstorm is an area of deep moist convection in which lightning is present. There are two primary types of thunderstorms; supercell and non-supercell. Several attempts have been made to quantify the discrimination of supercells and nonsupercells (e.g., Moller 1994; Thompson et al. 2003, hereafter T03; Hocker 2006) but common to each is the basic premise that a supercell is a thunderstorm possessing a deep, persistent mesocyclone: a storm-scale vortex spanning a significant depth of the convective storm, and persisting on the order of tens of minutes (the approximate convective timescale) The tools most commonly used for identifying supercell thunderstorms are numerical and visual examination of radar data. Typical supercell characteristics include the visual presence of a hook echo, inflow notch, bounded weak echo region (BWER), and motion deviating from that of the mean wind. Numerical characteristics include the magnitude and persistence of azimuthal shear. One topic of concern is the suggestion that supercells tend to produce a disproportionately high number of casualties
Novel Frontiers in High-Entropy Alloys

There is little doubt that there is significant potential for high-entropy alloys (HEAs) in cryogenic and aerospace applications. However, given the immense design space for HEAs, there is much more to be explored. This review will focus on four areas of application for HEAs that receive less attention. These focus areas include joining technologies, HEA nanomaterial synthesis, catalysis, and marine applications. The performance of HEAs as a filler metal for welding and brazing as well as their performance as a welded/brazed base metal will be discussed. Various methods for synthesizing HEA nanomaterials are reviewed with specifically highlighted applications in catalysis and energy storage. HEA catalysts, in particular, will be discussed in detail regarding their effectiveness, selectiveness, and stability. Marine applications are explored given the inherent corrosion resistance of HEAs as well as superior antifouling properties that make HEAs an intriguing marine-ready material.
Can heart rate variability data from the Apple Watch electrocardiogram quantify stress?

Chronic stress has become an epidemic with negative health risks including cardiovascular disease, hypertension, and diabetes. Traditional methods of stress measurement and monitoring typically relies on self-reporting. However, wearable smart technologies offer a novel strategy to continuously and non-invasively collect objective health data in the real-world. A novel electrocardiogram (ECG) feature has recently been introduced to the Apple Watch device. Interestingly, ECG data can be used to derive Heart Rate Variability (HRV) features commonly used in the identification of stress, suggesting that the Apple Watch ECG app could potentially be utilized as a simple, cost-effective, and minimally invasive tool to monitor individual stress levels. Here we collected ECG data using the Apple Watch from 36 health participants during their daily routines. Heart rate variability (HRV) features from the ECG were extracted and analyzed against self-reported stress questionnaires based on the DASS-21 questionnaire and a single-item LIKERT-type scale. Repeated measures ANOVA tests did not find any statistical significance. Spearman correlation found very weak correlations (p < 0.05) between several HRV features and each questionnaire. The results indicate that the Apple Watch ECG cannot be used for quantifying stress with traditional statistical methods, although future directions of research (e.g., use of additional parameters and Machine Learning) could potentially improve stress quantification with the device.

The Effect of Zirconia Nanoparticles on Thermal, Mechanical, and Corrosion Behavior of Nanocomposite Epoxy Coatings on Steel Substrates

Zirconia (ZrO2) nanoparticles (1–3 wt.%) were incorporated into the epoxy matrix using the ultra-sonication mixing method of dispersion to manufacture nanocomposite coatings. An automatic applicator was used to prepare the coating samples on a stainless steel substrate. The influence of ZrO2 nanoparticles on the physicochemical characteristics of epoxy coatings was evaluated using energy dispersive X-ray spectroscopy (EDS), field emission scanning electron microscopy (FE-SEM), Fourier-transform infrared spectroscopy (FTIR), thermos-gravimetric analysis (TGA), elastic modulus, and micro-hardness measurement with the nano-indentation technique. The corrosion stability during immersion in 3.5% NaCl solution was monitored using electrochemical impedance spectroscopy (EIS). All ZrO2-containing coatings showed better corrosion stability and adhesion than pure epoxy coating. Epoxy coating incorporated with 2% ZrO2 exhibited the greatest values of corrosion resistance and adhesion due to the effect of nanoparticle properties and their better de-agglomeration in the epoxy matrix than pure epoxy coating.
Recommending Collaborators Based on Co–Changed Files: A Controlled Experiment

Active collaboration is essential for the success of software projects across the development life-cycle. However, social coding platforms, like GitHub, present challenges in finding potential collaborators with whom they could create new/stronger ties and enhance the quality of contributions. Thus, we conducted a controlled experiment with 35 participants. We asked participants to perform the experiment tasks to find collaborators with similar interests using a prototype recommendation tool and GitHub. We observed that results confirm that recommender based on co–changed files can provide suitable collaborator recommendations to developers of a specific project.
Slip-enhanced drop formation in a liquid falling down a vertical fibre

For a liquid film falling down along a vertical fibre, classical theory (Kalliadasis & Chang J. Fluid Mech., vol. 261, 1994, pp. 135–168; Yu & Hinch J. Fluid Mech., vol. 737, 2013, pp. 232–248) showed that drop formation can occur due to capillary instability when the Bond number $G=\unicode[STIX]{x1D70C}ga^{3}/\unicode[STIX]{x1D6FE}h_{0}$ is below the critical value $G_{c}\approx 0.60$ , where $\unicode[STIX]{x1D70C}$ is the fluid density, $g$ is the gravitational acceleration, $a$ is the fibre radius, $\unicode[STIX]{x1D6FE}$ is the surface tension and $h_{0}$ is the unperturbed film thickness. However, the experiment by Quéré (Europhys. Lett., vol. 13 (8), 1990, pp. 721–726) found $G_{c}\approx 0.71$ , which is slightly greater than the above theoretical value. Here we offer a plausible way to resolve this discrepancy by including additional wall slip whose amount can be measured by the slip parameter $\unicode[STIX]{x1D6EC}=3\unicode[STIX]{x1D706}/h_{0}$ , where $\unicode[STIX]{x1D706}$ is the slip length. Using lubrication theory, we find that wall slip promotes capillary instability and, hence, enhances drop formation. In particular, when slip effects are strong ( $\unicode[STIX]{x1D6EC}\gg 1$ ), the transition films and the drop height scale as $(c/\unicode[STIX]{x1D6EC})^{-1/3}$ and $(c/\unicode[STIX]{x1D6EC})^{2/3}$ , respectively, distinct from those found by Yu & Hinch for the no-slip case where $c$ is the travelling speed. In addition, for $\unicode[STIX]{x1D6EC}>1$ , $G_{c}$ is found to increase with $\unicode[STIX]{x1D6EC}$ according to $G_{c}\approx 0.7\unicode[STIX]{x1D6EC}^{1/3}$ , offering a possible explanation why the $G_{c}$ found by Quéré is slightly greater than that predicted by the no-slip model. Using the above expression, the estimated slip length in Quéré’s experiment is found to be of the order of several micrometres, consistent with the typical slip length range 1– $10~\unicode[STIX]{x03BC}\text{m}$ for polymeric liquids such as silicone oil used in his experiment. The existence of wall slip in Quéré’s experiment is further supported by the observation that the film thinning kinetics exhibits the no-slip result $h\propto t^{-1/2}$ for early times and changes to the strong slip result $h\propto t^{-1}$ , where $h$ is the film thickness. We also show that when the film is ultrathin, although capillary instability can become further amplified by strong slip effects, the instability can be arrested by the equally intensified gravity draining in the weakly nonlinear regime whose dynamics is governed by the Kuramoto–Sivashinsky equation.
Generalized RMIL conjugate gradient method under the strong Wolfe line search with application in image processing

RMIL conjugate gradient method originally proposed by Rivaie et al. (2012) has recently gained lots of attention. In this article, we propose a generalized conjugate gradient parameter that contains both RMIL and its variant, that is, RMIL+, as special cases. We show that the search direction generated by the new method is sufficiently descent. Under standard mild conditions, we discuss the convergence analysis of the propose method. We demonstrate the numerical efficiency of the propose method on a set of unconstrained minimization benchmark test problems as well as an image restoration problem. The results of the experiment reveal that the proposed method performs better than its main competitors.
Early Experience with the Paul Glaucoma Implant in Childhood Glaucoma: A Case Series

Purpose The Paul glaucoma implant (PGI, Advanced Ophthalmic Innovations, Singapore, Republic of Singapore) is a recently developed novel non-valved glaucoma drainage device (GDD) designed to effectively reduce the intraocular pressure (IOP) in glaucoma patients with a theoretically reduced risk of postoperative complications such as hypotony, endothelial cell loss, strabismus, and diplopia. Limited literature has evaluated its use in adult glaucoma; however, its use in pediatric glaucoma has not been reported to date. We present our early experience with PGI in refractory childhood glaucoma. Patients and Methods This study was retrospective single-surgeon case series in a single tertiary center. Results Three eyes of 3 patients with childhood glaucoma were enrolled in the study. During nine months of follow-up, postoperative IOP and number of glaucoma medications were significantly lower than preoperative values in all the enrolled patients. None of the patients developed postoperative complications including postoperative hypotony, choroidal detachment, endophthalmitis, or corneal decompensation. Conclusion PGI is an efficient and relatively safe surgical treatment option in patients with refractory childhood glaucoma. Further studies with larger number of participants and longer follow-up period are required to confirm our encouraging results.
Bandler-Kohout Subproduct with Yager’s Families of Fuzzy Implications: A Comprehensive Study

Approximate reasoning schemes involving fuzzy sets are one of the best known applications of fuzzy logic in the wider sense. Fuzzy Inference Systems (FIS) or Fuzzy Inference Mechanisms (FIM) have many degrees of freedom, viz., the underlying fuzzy partition of the input and output spaces, the fuzzy logic operations employed, the fuzzification and defuzzification mechanism used, etc. This freedom gives rise to a variety of FIS with differing capabilities.
Small Signal Modeling and Transient Cross-Regulation Analysis of Peak-Current-Mode-Controlled SIDO Buck LED Driver

Single-inductor dual-output (SIDO) dc–dc converter has been applied to light-emitting diode (LED) drivers with its advantages of small volume and low cost. Peak-current-mode (PCM) control of the SIDO converter has the advantages of fast transient performance and suppressed cross-regulation. A PCM-controlled SIDO buck LED driver to achieve independent dimming and to eliminate the steady-state cross-regulation is proposed in this article. The circuit and the principle of the PCM-controlled SIDO buck LED driver are presented, and its small signal model is established based on inductor current ripple. Furthermore, based on control-to-output loop gain transfer functions, control parameters of PCM-controlled SIDO buck LED driver are designed to achieve independent output current regulation of each LED driver. Besides, cross-regulation transfer functions are obtained to investigate the effect of reference signals and control parameters on the transient cross-regulation. Moreover, the effect of capacitor parameters on the stability of the LED driver is analyzed based on the bifurcation diagram. Finally, experimental results are provided to show the independent dimming capability of PCM-controlled SIDO buck LED driver with designed parameters, and the validity of the theoretical analysis on transient cross-regulation and stability of the LED driver.
Association of Emotional and Cognitive Intimacy With Promiscuous Married Men Through Mediating Role of Attitude Towards Infidelity

Background: Promiscuity and attitude towards infidelity can harm family health and cause many family problems. They are also two important reasons for divorce and separation. This study aimed to investigate the association of emotional and cognitive intimacy with promiscuity through the mediating role of attitude towards infidelity in married men. Methods: This applied descriptive study had a correlational design and adopted the structural equation modeling method. The statistical population included all married men in Bushehr (Iran) who visited marriage counseling centers in 2020. A total of 384 married men were selected as the sample using convenience sampling. The research tools included the Personal Assessment of Intimacy in Relationships, Attitudes towards Infidelity Scale, and the Justifications for Extramarital Relationships. Data were analyzed via the Pearson correlation method and structural equation modeling. SPSS version-24 and AMOS-24 were further used for analyzing the data. Results: The results indicated that there was a direct association between emotional intimacy and attitude towards infidelity (β=0.18, P=0.001), cognitive intimacy and attitude towards infidelity (β=-0.62, P=0.001), emotional intimacy and promiscuity (β=0.11, P=0.014), attitude towards infidelity and promiscuity (β=0.68, P=0.001), but there was no a significant association between cognitive intimacy and promiscuity. The findings also revealed a significant relationship of emotional (β=0.19, P=0.009) and cognitive (β=-0.39, P=0.007) intimacy and promiscuity with mediating role of attitude towards infidelity in men. Conclusion: In general, this study revealed that emotional-cognitive intimacy is a predictor of promiscuity. Therefore, the findings can contribute to studies that lead to marital stability.
Single-scale center-surround Retinex based restoration of low-illumination images with edge enhancement

Restoring images captured under low-illuminations is an essential front-end process for most image based applications. The Center-Surround Retinex algorithm has been a popular approach employed to improve image brightness. However, this algorithm in its basic form, is known to produce color degradations. In order to mitigate this problem, here the Single-Scale Retinex algorithm is modiﬁed as an edge extractor while illumination is recovered through a non-linear intensity mapping stage. The derived edges are then integrated with the mapped image to produce the enhanced output. Furthermore, in reducing color distortion, the process is conducted in the magnitude sorted domain instead of the conventional Red-Green-Blue (RGB) color channels. Experimental results had shown that improvements with regard to mean brightness, colorfulness, saturation, and information content can be obtained.
Cuproptosis-related lncRNAs predict prognosis and immune response of thyroid carcinoma

Objective: To estimate the survival and prognosis of patients with thyroid carcinoma (THCA) based on the Long non-coding RNA (lncRNA) traits linked to cuproptosis and to investigate the connection between the immunological spectrum of THCA and medication sensitivity. Methods: RNA-Seq data and clinical information for THCA were obtained from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. We built a risk prognosis model by identifying and excluding lncRNAs associated with cuproptosis using Cox regression and LASSO methods. Both possible biological and immune infiltration functions were investigated using Principal Component Analysis (PCA), Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and immunoassays. The sensitivity of the immune response to possible THCA medicines was assessed using ratings for tumor immune dysfunction and exclusion (TIDE) and tumor mutational burden (TMB). Results: Seven cuproptosis-related lncRNAs were used to construct our prognostic prediction model: AC108704.1, DIO3OS, AL157388.1, AL138767.3, STARD13-AS, AC008532.1, and PLBD1-AS1. Using data from TCGA’s training, testing, and all groups, Kaplan-Meier and ROC curves demonstrated this feature’s adequate predictive validity. Different clinical characteristics have varying effects on cuproptosis-related lncRNA risk models. Further analysis of immune cell infiltration and single sample Gene Set Enrichment Analysis (ssGSEA) supported the possibility that cuproptosis-associated lncRNAs and THCA tumor immunity were closely connected. Significantly, individuals with THCA showed a considerable decline in survival owing to the superposition effect of patients in the high-risk category and high TMB. Additionally, the low-risk group had a higher TIDE score compared with the high-risk group, indicating that these patients had suboptimal immune checkpoint blocking responses. To ensure the accuracy and reliability of our results, we further verified them using several GEO databases. Conclusion: The clinical and risk aspects of cuproptosis-related lncRNAs may aid in determining the prognosis of patients with THCA and improving therapeutic choices.

A milli-joule level vortex output was generated at a low lasing threshold (1.2 mJ), with its wavelength being tuned within a range of 1.85-2.03 μm.
A Supertough, Nonflammable, Biomimetic Gel with Neuron‐Like Nanoskeleton for Puncture‐Tolerant Safe Lithium Metal Batteries

To overcome the critical safety and performance issues of lithium metal batteries, it is urgent to develop advanced electrolytes with multi‐defensive properties against fire, mechanical puncture, and dendrite growth simultaneously, in addition to high ion‐conductivity. However, realizing these essential properties by one electrolyte has proved to be extremely challenging due to the inherent conflicts among them. Herein, to circumvent this challenge, a neuron‐like gel polymer electrolyte (simply referred as Neu‐PE) to simultaneously achieve supertoughness, nonflammability, dendrite‐suppression capability and self‐driven property is reported. This Neu‐PE takes advantage of nano‐phase separation regulated by highly ion‐conductive deep‐eutectic solvent. As a result, the Neu‐PE holds high ambient ionic conductivity (1.27±0.09 mS cm−1), super‐toughness and strength (22.52 MJ m−3 and 13.5±0.6 MPa), fire resistance and importantly, lithium‐metal anode protection capability. Lithium metal batteries assembled with this multi‐defensive Neu‐PE can work normally even under metal‐probe puncture or serious damage by cutting.
