Under the Radar: Muslims Deported, Detained, and Denied on Unsubstantiated Terrorism Allegations

Through the targeted use of a wide set of immigration and law enforcement policies and actions, the U.S. government has cast Muslims as dangerous threats to national security, leaving Muslim communities across the United States vulnerable to discrimination and discriminatory profiling. This Briefing Paper by the Center for Human Rights and Global Justice (CHRGJ) and the Asian American Legal Defense and Education Fund (AALDEF) documents the U.S. government's deployment of lower evidentiary standards and lack of due process guarantees in the immigration system against Muslims to further marginalize this targeted group in the name of national security and counterterrorism. A number of particular immigration programs and practices -- such as the National Security Entry-Exit Registration System (NSEERS),the Federal Bureau of Investigation (FBI) name-check system in the naturalization process, and racial profiling at U.S. borders have received critical attention for their discriminatory impacts on Muslim communities. This Briefing Paper draws on interviews with immigration and criminal defense attorneys and community-based groups, court documents, and media accounts to identify five key under-documented patterns of government practices that appear to be targeting Muslim communities through the immigration system

Light Sensing Property of Amorphous Silicon Thin Film pin Diode: Solar Cell and Photodiode

The performance and stress-induced degradation of a-Si:H solar cells with pin and nip stacked structures prepared in the single chamber PECVD have been studied. The property of the i-layer depends on the sequence of film deposition because the intrinsic (i)-layer is contaminated by the dopant residue in the chamber remaining from the previous deposition step. This affects the solar cell performance, degradation, as well as recovery. Also, the cell degradation under the electric-stress condition with and without the simultaneous light exposure has been studied. The light sensing characteristics of the a-Si:H pin diode composed of both top and bottom ITO electrodes with respect to the power density of red (625nm), green (530nm), and blue (470nm) illumination lights have been studied. The study’s findings indicate that the light detection of the diode is affected by both the wavelength and power density of the incident light. Such influence turns out to be due to the dependence of the asymmetric carrier loss on the light wavelength and power density. Also, changes in pin diode characteristics have been confirmed by internal resistances, short circuit current density, and open circuit voltage, as well as the application of a bottom light reflector. The mechanism of asymmetric carrier transfers in the light-sensing of the a-Si:H pin diode has been discussed using different i-layer thickness, combined electric-optical stress method, and three narrow-band lights. The position of the photo-generated electron-hole pairs within the i-layer varies with the wavelength of the incident light, which directly affects the asymmetric transfer and loss of the carriers. This has been confirmed with the i-layer thickness and combined electric-optical stress method

Electric generator embedded in cellular phone for self-recharge

Nowadays, due to the development of information industry and technologies, the objective of cellular phone is not only to communicate, but also to give people various functions such as e-banking, web surfing and even excitement and fun. Because of increased usage of the cellular phone, the available time of the phone rechargeable battery is getting shorter. Therefore, in order to extend the serviceable time of the rechargeable battery, we propose self-generation system using a tubular type of permanent magnet linear self-generator (TPMLG) which can be embedded in cellular phone. The vibrational model is studied utilizing the mechanical resonance and the magnetic circuit such as permanent magnet, steel yoke and coil is designed to improve electricity generation. To investigate the electric characteristics of designed generation system, the transient finite element analysis using commercial software “MAXWELL” is performed

Unbiased Heterogeneous Scene Graph Generation with Relation-aware Message Passing Neural Network

Recent scene graph generation (SGG) frameworks have focused on learning complex relationships among multiple objects in an image. Thanks to the nature of the message passing neural network (MPNN) that models high-order interactions between objects and their neighboring objects, they are dominant representation learning modules for SGG. However, existing MPNN-based frameworks assume the scene graph as a homogeneous graph, which restricts the context-awareness of visual relations between objects. That is, they overlook the fact that the relations tend to be highly dependent on the objects with which the relations are associated. In this paper, we propose an unbiased heterogeneous scene graph generation (HetSGG) framework that captures relation-aware context using message passing neural networks. We devise a novel message passing layer, called relation-aware message passing neural network (RMP), that aggregates the contextual information of an image considering the predicate type between objects. Our extensive evaluations demonstrate that HetSGG outperforms state-of-the-art methods, especially outperforming on tail predicate classes.Comment: 9 pages; AAAI 202

Comparing Classroom Note Taking across Multiplatform Devices

Many educators have suggested that note taking can be beneficial for the students' educational growth. Note taking is the core activity for students in a classroom and there been a large amount of research conducted, both from industry and from academia, into facilitating the note taking process. As such, there are many available systems for taking notes. However, what has not been given as much attention is how different devices, such as Tablet PCs and PDAs, effect this task. In this paper, we study students' current note taking behavior and the changes caused by the use of different platforms for this activity. Our goal is to provide ideas and general design guidelines for future note taking systems

The Effect of Electrical Muscle Stimulation and In-bed Cycling on Muscle Strength and Mass of Mechanically Ventilated Patients: A Pilot Study

Background Critically ill patients experience muscle weakness, which leads to functional disability. Both functional electrical stimulation (FES) and in-bed cycling can be an alternative measure for intensive care unit (ICU) patients who are not feasible for active exercise. The aim of this study was to examine whether FES and in-bed cycling have a positive effect on muscle mass in ICU patients. Methods Critically ill patients who received mechanical ventilation for at least 24 hours were included. After passive range of motion exercise, in-bed cycling was applied for 20 minutes, and FES was applied for 20 minutes on the left leg. The right leg received in-bed cycling and the left leg received both FES and in-bed cycling. Thigh circumferences and rectus femoris cross-sectional area (CSA) were assessed with ultrasonography before and after the intervention. Muscle strength was assessed by Medical Research Council scale. Results A total of 10 patients were enrolled in this study as a pilot study. Before and after the intervention, the CSA of right rectus femoris increased from 5.08 ± 1.51 cm2 to 6.01 ± 2.21 cm2 , which was statistically significant (P = 0.003). The thigh circumference was also increased and statistically significant (P = 0.006). There was no difference between left and right in regard to FES application. There is no significant change in muscle strength before and after the intervention (right and left, P = 0.317 and P = 0.368, respectively). Conclusions In-bed cycling increased thigh circumferences rectus femoris CSA. Adding FES did not show differences

O-GlcNAc modification of leucyl-tRNA synthetase 1 integrates leucine and glucose availability to regulate mTORC1 and the metabolic fate of leucine

All living organisms have the ability to sense nutrient levels to coordinate cellular metabolism. Despite the importance of nutrient-sensing pathways that detect the levels of amino acids and glucose, how the availability of these two types of nutrients is integrated is unclear. Here, we show that glucose availability regulates the central nutrient effector mTORC1 through intracellular leucine sensor leucyl-tRNA synthetase 1 (LARS1). Glucose starvation results in O-GlcNAcylation of LARS1 on residue S1042. This modification inhibits the interaction of LARS1 with RagD GTPase and reduces the affinity of LARS1 for leucine by promoting phosphorylation of its leucine-binding site by the autophagy-activating kinase ULK1, decreasing mTORC1 activity. The lack of LARS1 O-GlcNAcylation constitutively activates mTORC1, supporting its ability to sense leucine, and deregulates protein synthesis and leucine catabolism under glucose starvation. This work demonstrates that LARS1 integrates leucine and glucose availability to regulate mTORC1 and the metabolic fate of leucine. Leucyl-tRNA synthetase 1 (LARS1) is a leucine sensor for mTORC1 signaling and regulates leucine utilization depending on glucose availability. Here, the author show that O-GlcNAcylation of LARS1 is crucial for its ability to regulate mTORC1 activity and leucine metabolism upon glucose starvation

Metal-free, polyether-mediated H_2-release from ammonia borane: roles of hydrogen bonding interactions in promoting dehydrogenation

Polyetheral additives were found to be efficient promoters to enhance the rate of H2-release from ammonia borane (AB) at various temperatures. In particular, tetraethylene glycol dimethyl ether (T4EGDE, 29 wt% relative to AB + T4EGDE) exhibited significantly improved activities for AB dehydrogenation, with the material-based hydrogen storage capacity of 10.3 wt% at 125 °C within 40 min. In situ FT-IR spectroscopy indicated the formation of B-(cyclodiborazanyl)amino-borohydride (BCDB), borazine, and μ-aminodiborane as gaseous byproducts. In addition, 11B nuclear magnetic resonance (NMR) spectroscopy further revealed that diammoniate of diborane (DADB) was initially formed to give polyaminoborane as liquid and/or solid spent-fuel, consistent with previous reports. Density Functional Theory (DFT) calculations suggested that hydrogen bonding interactions between AB and a polyetheral promoter initially played an important role in increasing the reactivity of B–H bonds of AB by transferring electron density from oxygen atoms of the promoter into B–H bonds of AB. These partially activated, hydridic B–H bonds were proposed to help promote the formation of diammoniate of diborane (DADB), which is considered as a reactive intermediate, eventually enhancing the rate of H2-release from AB. In addition, our in situ solid state 11B magic angle spinning (MAS) NMR measurements further confirmed that the rate of DADB formation from AB with a small quantity of T4EGDE was found to be much faster than that of pristine AB even at 50 °C. This metal-free method for H2-release from AB with an added, small quantity of polyethers would be helpful to develop feasible hydrogen storage systems for long-term fuel cell applications

Non-invasive digital etching of van der Waals semiconductors

The capability to finely tailor material thickness with simultaneous atomic precision and non-invasivity would be useful for constructing quantum platforms and post-Moore microelectronics. However, it remains challenging to attain synchronized controls over tailoring selectivity and precision. Here we report a protocol that allows for non-invasive and atomically digital etching of van der Waals transition-metal dichalcogenides through selective alloying via low-temperature thermal diffusion and subsequent wet etching. The mechanism of selective alloying between sacrifice metal atoms and defective or pristine dichalcogenides is analyzed with high-resolution scanning transmission electron microscopy. Also, the non-invasive nature and atomic level precision of our etching technique are corroborated by consistent spectral, crystallographic and electrical characterization measurements. The low-temperature charge mobility of as-etched MoS$_2$ reaches up to $1200\,$cm$^{2}\cdot$V$^{-1}\cdot$s$^{-1}$, comparable to that of exfoliated pristine counterparts. The entire protocol represents a highly precise and non-invasive tailoring route for material manipulation.Comment: 46 pages, 4 figures, with S
