LiCA: A Fine-grained and Path-sensitive Linux Capability Analysis Framework

The capability mechanism in Linux-based systems is designed for dispersing the root privileges into a set of more refined capabilities, making programs gain no-more-necessary privileges. However, it is challenging to check the necessity and sufficiency of capabilities assigned to programs due to the highly complicated call chains invoked in practice. Inappropriate capability assignment brings threats to the systems. For example, over-privileged programs could allow an attacker to misuse root privileges, while under-privileged programs may incur runtime errors. In this paper, we propose a new Linux capability analysis framework called LiCA to find necessary and sufficient capabilities for programs effectively. LiCA presents fine-grained and path-sensitive code flow analysis based on LLVM to construct accurate mappings between system calls and their capabilities. In particular, we solve the constraint equations along each path from a given system call to individual capabilities and strategically overcome the path explosion problem. Our experiments show that LiCA can correctly find necessary capabilities for the Linux utility programs (e.g., ping and tcpdump) and the public programs from GitHub. By comparing the capabilities claimed by program developers and the results from LiCA, we identify a batch of programs requiring more capabilities than necessary, even root privileges. Therefore, LiCA could help those third-party developers validate their programs’ capability setting to achieve the least privilege principle.
Distributed Denial of Service (DDoS) Mitigation: Security Awareness Domain and Resources (SADAR)

Information security is a constantly evolving field to safeguard confidentiality, integrity and assets with defensive measures should be developed and planned to improve information security. Therefore, it is very important for a company to update its security system and defense techniques from attacks that occur. Furthermore, Distributed Denial of Service (DDoS) attack is a major threat that can disrupt and hinder legitimate service requests on a network. They were first reported in 1996 and until now the complexity and sophistication of these attacks is increasing, which are usually used to force a site or service to go offline, that is, by passing high data traffic until the server cannot work. Meanwhile, In August 2021, Microsoft claimed to have succeeded in overcoming the largest DDoS attack reaching 2 TBps. Moreover, with the increasing number of DDoS attacks, a mitigation scenario is needed to deal with the complexity and technical development of this DDoS. In the network world, detecting a DDoS somehow, is extremely difficult because the attempt should distinguish between normal traffic and DDoS attacks. Thus, some recommended security solutions will be compiled in this paper to deliver solution involving the mitigation.
WikipediaBot: Machine Learning Assisted Adversarial Manipulation of Wikipedia Articles

This paper presents an automated adversarial mechanism called WikipediaBot. WikipediaBot allows an adversary to create and control a bot infrastructure for the purpose of adversarial edits of Wikipedia articles. The WikipediaBot is a self-contained mechanism with modules for generating credentials for Wikipedia editors, bypassing login protections, and a production of contextually-relevant adversarial edits for target Wikipedia articles that evade conventional detection. The contextually-relevant adversarial edits are generated using an adversarial Markov chain that incorporates a linguistic manipulation attack known as MIM or malware-induced misperceptions. We conducted a preliminary qualitative analysis with a small focus group to test the effect of the adversarial edits in manipulating the perception a human reader has about a target Wikipedia article. Because the nefarious use of WikipediaBot could result in harmful damages to the integrity of a wide range of Wikipedia articles, we provide an elaborate discussion about the implications, detection, and defenses Wikipedia could employ to address the threat of automated adversarial manipulations.

Quantum Entanglement Dynamics of Two Atoms in Two Coupled Cavities

Quantum entanglement dynamics for two atoms trapped in two coupled cavities is investigated. Numerical results show that the present of the two atomic excitations is mainly accounted for the entanglement-sudden-death (ESD) effect with the two cavities initially in the vacuum. The entanglement can also be controlled by the hopping rate and the imbalances between the two atom-cavity coupling rates.

5.3: Brightness Decline Mechanism at Low Frequency Display on LTPS LCD

The current high‐frequency LTPS LCD panel cannot reach the low‐frequency specification of less than 30Hz display. We evaluated the leakage current & flicker value correspondence relationship through a simplified model, then we measured the time‐brightness curve at 15Hz display and found brightness change in one frame includes three different stages. Therefore, effective measures are proposed to improve image flicker performance. Finally, a 6.58‐inch FHD LTPS‐LCD with 15~165Hz display was achieved without optimization of pixel TFT leakage current.

This function describes everything that can be seen, as defined by Adelson [1] by Where ,  corresponds to the orientation or direction of a ray depending on the intensity with wavelength of  . t is the time dimension, and corresponds to a point in space [2] . We introduce the plenoptic function for backlight directional display illumination, which requires angular and position invariant smoothness on the display surfac e [3-4] . , x z P
P‐2.7: Optimization of Field of View in a Full‐color Waveguide Display Based on Polarization Volume Grating

We propose a PVG‐based bandwidth composite structure, explore the multi‐period formation method and bandwidth expansion characteristics of the composite grating, and study different color waveguide display schemes. We analyzed the advantages and disadvantages of full‐color waveguide displays with one‐, two‐ and three‐layer waveguides. Finally, based on the grating bandwidth composite structure, a two‐layer waveguide is designed and fabricated to achieve full‐color near‐eye display. The display effect is shown on the AR display prototype. The demonstrated waveguide system is a full‐color display with a diagonal field of view of about 50�. The brightness is as high as 242 cd/m2 per lumen with a transparency of 75% for ambient light. This work shows the good application prospect of PVG coupler in augmented reality color display.
P‐2.4: Development and Prospect of Medical Action Recognition Technology forVirtual Reality (VR)

In recent years, the rapid development of artificial intelligence and computer vision technology has played a vital role in the advancement of medicine. The application of motion recognition technology based on virtual reality to the process of medical rescue and training is an important development direction at present. Gesture recognition needs to consider the dynamic relationship between the front and back of the hand, target detection, and space‐time transformation, but its application in medical surgery is challenging. This paper introduces the development of gesture recognition technology and equipment, introduces the target detection, processing, feature extraction, motion estimation and motion recognition technology in virtual reality‐based surgical motion recognition, discusses the current mainstream virtual reality‐based surgical motion recognition development, and makes a developing prospect.

56.3: Invited Paper: Exterior Displays for Autonomous Cars: Technologies, Icons, Evaluation

Communication with other road users is very essential for autonomous as they might drive slower and the person on the driver's seat does not necessarily look on the street. To evaluate exterior displays, we build a full‐scale mock‐up with a RGB LEDs matrix display with 80 cm × 40 cm (128 × 64 pixel). Even text with a height of 10 cm was judged as readable from 50 m distance. Other results were the identification of signs with 40 cm height from 50 m. This is in accordance with common traffic sign standards.
40.1: Invited Paper: Flat Liquid Crystal Optics for AR/VR Applications

As the next-generation display and communication platforms, augmented reality (AR) and virtual reality (VR) [1] headsets have experienced significant booming due to the development of 5G networks and the increasing demands for working remotely. AR and VR can bring unprecedented experience for gaming, education, medical care and automotive display [2-5] because of their three-dimensional vision, immersive experience and interactive user interface, therefore extensive efforts are made by leading companies like Meta, Microsoft, Magic Leap and Focals by North. The current challenges for AR and VR include how to optimize the system form factor, the field of view (FoV), eyebox, energy consuming and display resolution [6
P‐1.2: Improvement of Mobility and Reliability of a‐IGZO TFTs by Dual‐Gate Driving

In this work, a IGZO thin‐film transistor with double‐gate structure is studied to realize high mobility and strong reliability simultaneously. Enhancement‐mode operation that is essential to the constitution of a low‐power digital circuitry and high current demand of mini‐LED and micro‐LED display is easily achieved when the top and bottom gate electrodes are tied together. The device mobility and the subthreshold swing are improved from 16.2 cm2/Vs and 0.29V/dec to 22.4 cm2/Vs and 0.24V/dec, respectively, compared with the single‐gate (SG) structure. High mobility is attributed to the dual channel of double gate coupling. Finally, the mechanism of NBTiS improvement also has clarified in terms of energy band and electric field of the double gate structure.
KNOWN PULSARS IDENTIFIED IN THE GMRT 150 MHz ALL-SKY SURVEY

We have used the 150 MHz radio continuum survey (TGSS ADR) from the Giant Metrewave Radio Telescope (GMRT) to search for phase-averaged emission toward all well-localized radio pulsars north of −53° decl. We detect emission toward 200 pulsars with high confidence ( ) and another 88 pulsars at fainter levels. We show that most of our identifications are likely from pulsars, except for a small number where the measured flux density is confused by an associated supernova or pulsar-wind nebula, or a globular cluster. We investigate the radio properties of the 150 MHz sample and find an unusually high number of gamma-ray binary millisecond pulsars with very steep spectral indices. We also note a discrepancy in the measured flux densities between GMRT and LOFAR pulsar samples, suggesting that the flux density scale for the LOFAR pulsar sample may be in error by approximately a factor of two. We carry out a separate search of 30 well-localized gamma-ray, radio-quiet pulsars in an effort to detect a widening of the radio beam into the line of sight at lower frequencies. No steep-spectrum emission was detected either toward individual pulsars or in a weighted stack of all 30 images.
5: Optical realization of 360° cylindrical holography with planer SLM

Holographic display can provide the required all parallax and depth information for the human eyes, which is regarded as a promising display technique for truly realizing 3D displays and a kind of core technique of Metaverse. Computer-generated hologram(CGH) is a key technology for realizing 3D displays based on digitally recording holograms of 3D virtual objects. Generally, holograms are loaded onto a planar SLM, meanwhile the field of view (FOV) is limited by the size and pixel pitch of SLM [1]. Cylindrical computer-generated holograms are considered ideal for extending FOV since it has a 360° look-around property, providing a better immerse experience which is a core technology of Metaverse [2]. However, there is currently no commercial cylindrical SLM available for the cylindrical holographic display. In this paper, an optical realization of 360° cylindrical holography is proposed by using isophase surface transformation within visible light with a commercial planar SLM. In the propose method, a brand new diffraction model is proposed to convert the isophase surface of the diffracted field from a plane to a cylinder by using a 45° conical mirror. In order to derive the diffraction formula of the model, the whole diffraction process is divided into three stages: plane-to-plane diffraction, planeto-cylinder diffraction, and cylinder-to-cylinder diffraction. The schematic of the model is shown in Fig. 1.
Random Measure Algebras Under Convolution

Author(s): Park, Jason Hong Jae | Advisor(s): Rao, Malempati M | Abstract: In this thesis, we investigate a convolution product between random measures. The key importance of convolution is the convolution product of random measures is again the random measure. Since the operation is closed, a ring structure of random measures can be built. The covariance function of the random measure plays a key role in this research since each random measure has its corresponding covariance function.
A Robust Measurement of the Mass Outflow Rate of the Galactic Outflow from NGC 6090

To evaluate the impact of stellar feedback, it is critical to estimate the mass outflow rates of galaxies. Past estimates have been plagued by uncertain assumptions about the outflow geometry, metallicity, and ionization fraction. Here we use Hubble Space Telescope ultraviolet spectroscopic observations of the nearby starburst NGC 6090 to demonstrate that many of these quantities can be constrained by the data. We use the Si~{\sc IV} absorption lines to calculate the scaling of velocity (v), covering fraction (C$_f$), and density with distance from the starburst (r), assuming the Sobolev optical depth and a velocity law of the form: v$~\propto(1 -\mathrm{R}_\mathrm{i}/\mathrm{r} )^\beta$ (where R$_\mathrm{i}$ is the inner outflow radius). We find that the velocity ($\beta$=0.43) is consistent with an outflow driven by an r$^{-2}$ force with the outflow radially accelerated, while the scaling of the covering fraction ($C_f \propto \mathrm{r}^{-0.82}$) suggests that cool clouds in the outflow are in pressure equilibrium with an adiabatically expanding medium. We use the column densities of four weak metal lines and CLOUDY photoionization models to determine the outflow metallicity, the ionization correction, and the initial density of the outflow. Combining these values with the profile fitting, we find R$_\mathrm{i}$ = 63 pc, with most of the mass within 300~pc of the starburst. Finally, we find that the maximum mass outflow rate is 2.3~M$_\odot$ yr$^{-1}$ and the mass loading factor (outflow divided by the star formation rate) is 0.09, a factor of 10 lower than the value calculated using common assumptions for the geometry, metallicity and ionization structure of the outflow.
A combinatorial and field theoretic path to quantum gravity: the new challenges of group field theory

Group field theories are a new type of field theories over group manifolds and a generalization of matrix models, that have recently attracted much interest in quantum gravity research. They represent a development of and a possible link between different approaches such as loop quantum gravity and simplicial quantum gravity. After a brief introduction to the GFT formalism we put forward a long but still far from exhaustive list of open issues that this line of research faces, and that could be represent interesting challenges for mathematicians and mathematical physicists alike.
GAMMA-RAY OBSERVATIONS OF THE ORION MOLECULAR CLOUDS WITH THE FERMI LARGE AREA TELESCOPE

We report on the gamma-ray observations of giant molecular clouds Orion A and B with the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope. The gamma-ray emission in the energy band between ∼100 MeV and ∼100 GeV is predicted to trace the gas mass distribution in the clouds through nuclear interactions between the Galactic cosmic rays (CRs) and interstellar gas. The gamma-ray production cross-section for the nuclear interaction is known to ∼10% precision which makes the LAT a powerful tool to measure the gas mass column density distribution of molecular clouds for a known CR intensity. We present here such distributions for Orion A and B, and correlate them with those of the velocity-integrated CO intensity (WCO) at a 1° × 1° pixel level. The correlation is found to be linear over a WCO range of ∼10-fold when divided in three regions, suggesting penetration of nuclear CRs to most of the cloud volumes. The WCO-to-mass conversion factor, XCO, is found to be ∼2.3 × 1020 cm-2(K km s−1)−1 for the high-longitude part of Orion A (l > 212°), ∼1.7 times higher than ∼1.3 × 1020 found for the rest of Orion A and B. We interpret the apparent high XCO in the high-longitude region of Orion A in the light of recent works proposing a nonlinear relation between H2 and CO densities in the diffuse molecular gas. WCO decreases faster than the H2 column density in the region making the gas “darker” to WCO.
JELLYFISH GALAXY CANDIDATES AT LOW REDSHIFT

Galaxies that are being stripped of their gas can sometimes be recognized from their optical appearance. Extreme examples of stripped galaxies are the so-called “jellyfish galaxies” that exhibit tentacles of debris material with a characteristic jellyfish morphology. We have conducted the first systematic search for galaxies that are being stripped of their gas at low-z (z = 0.04−0.07) in different environments, selecting galaxies with varying degrees of morphological evidence for stripping. We have visually inspected B- and V-band images and identified 344 candidates in 71 galaxy clusters of the OMEGAWINGS+WINGS sample and 75 candidates in groups and lower mass structures in the PM2GC sample. We present the atlas of stripping candidates and a first analysis of their environment and their basic properties, such as morphologies, star formation rates and galaxy stellar masses. Candidates are found in all clusters and at all clustercentric radii, and their number does not correlate with the cluster velocity dispersion σ or X-ray luminosity LX. Interestingly, convincing cases of candidates are also found in groups and lower mass halos (1011−1014M⊙), although the physical mechanism at work needs to be securely identified. All the candidates are disky, have stellar masses ranging from log M/M⊙ < 9 to > 11.5 and the majority of them form stars at a rate that is on average a factor of 2 higher (2.5σ) compared to non-stripped galaxies of similar mass. The few post-starburst and passive candidates have weak stripping evidence. We conclude that disturbed morphologies suggestive of stripping phenomena are ubiquitous in clusters and could be present even in groups and low mass halos. Further studies will reveal the physics of the gas stripping and clarify the mechanisms at work.
Helium-Shell Nucleosynthesis and Extinct Radioactivities

Although the exact site for the origin of the r-process isotopes remains mysterious, most thinking has centered on matter ejected from the cores of massive stars in core-collapse supernovae [13]. In the 1970's and 1980's, however, difficulties in understanding the yields from such models led workers to consider the possibility of r-process nucleosynthesis farther out in the exploding star, in particular, in the helium burning shell [4,5]. The essential idea was that shock passage through this shell would heat and compress this material to the point that the reactions 13C(alpha; n)16O and, especially, 22Ne(alpha; n)25Mg would generate enough neutrons to capture on preexisting seed nuclei and drive an "n process" [6], which could reproduce the r-process abundances. Subsequent work showed that the required 13C and 22Ne abundances were too large compared to the amounts available in realistic models [7] and recent thinking has returned to supernova core material or matter ejected from neutron star-neutron star collisions as the more likely r-process sites.
Metric convexity in the symplectic category

We introduce an extension of the standard Local-to-Global Principle used in the proof of the convexity theorems for the momentum map to handle closed maps that take values in a length metric space. This extension is used to study the convexity properties of the cylinder valued momentum map introduced by Condevaux, Dazord, and Molino in [8] and allows us to obtain the most general convexity statement available in the literature for momentum maps associated to a symplectic Lie group action.
