Members of the San Diego Police Department collect evidence at the scene of a fatal police officer involved shooting of a 15-year-old boy in one of the parking lots in front of Torrey Pines High School, early Saturday morning. The boy reportedly called the police and when they arrived pointed what appears to be a gun at them. (Howard Lipin/The San Diego Union-Tribune via AP) SAN DIEGO (AP) — Police shot and killed a 15-year-old student Saturday after he pointed a BB gun at them in a high school parking lot, authorities said. The Torrey Pines High School student called 911 shortly before 3:30 a.m. to ask officers to check on the welfare of an unarmed boy in front of the school, according to a police statement. He didn't name the boy, but investigators later determined he was referring to himself, police said. When two officers arrived, they spotted a youth in the front parking lot. But as they got out of their patrol cars, he pulled a gun from his waistband and pointed it at an officer, police said. The officers drew their guns and ordered him to drop the weapon. But instead he began to walk toward an officer, ignoring more demands to drop the weapon, police said. Both officers fired, hitting him several times. They performed first aid and summoned paramedics, but the teen was pronounced dead at a hospital, police said. The gun was found to be a BB air pistol. Police didn't release the teen's name because of his age. "Our hearts go out to the student, his family and his friends," said a statement from Eric Dill, superintendent of the San Diego Union High School District. A crisis-response team will be on campus Monday to support students, staff and parents, Dill said. Counseling also will be available at all district schools for anyone who needs a place to talk about the shooting or "to mourn and process this tragedy," he said.

People gathered at Torrey Pines High School on Sunday, May 7, 2017, in San Diego, near a memorial for a 15 year-old student that was shot and killed by police in the parking lot the day before. (K.C. Alfred /The San Diego Union-Tribune via AP) SAN DIEGO (AP) — A 15-year-old boy killed by police after pointing a BB gun at them wrote a suicide note indicating he planned to have officers shoot him, authorities said Monday. Lt. Mike Holden said police found the suicide note in the Torrey Pine High School student's jacket and it indicated he planned to call police so he would be shot and killed. Police say the boy called 911 at 3:27 a.m. Saturday to ask officers to check on the welfare of an unarmed boy in front of the school. When two officers arrived, they spotted a youth in the front parking lot. As they got out of their patrol cars, he pulled a gun from his waistband and pointed it at an officer, police said. The officers drew their guns and repeatedly ordered him to drop the weapon. But instead, he began to walk toward an officer, ignoring the orders, police said. The department said in a statement that both officers feared for their safety and fired, hitting the teen several times. They performed first aid and called paramedics. The teen was pronounced dead at a hospital. The gun was found to be a "semi-automatic BB air pistol," according to police. The officers, one a 28-year veteran of the San Diego department, and the other a four-year veteran, were wearing body cameras. Police didn't release the teen's name because of his age. He lived with his family in the affluent neighborhood near the coast. The San Dieguito Union High School District said in a statement that it was sending a crisis-response team to the campus Monday to support students, staff and parents. Superintendent Eric Dill said in a letter on the district's website that "our hearts go out to the student, his family, and his friends." "This is a difficult time for the family and we need to let them mourn," Dill said in the letter. Dill added that the district will strive to maintain the daily routine while offering support to people. In October, police in South Los Angeles fatally shot a 16-year-old boy who pointed a fake gun at officers. The teen had used his cellphone to call 911 to report a man with a gun. Police say it turned out to be a replica with an orange tip that had been painted black. The teen left a farewell note to his family. This story corrects name of school district to San Dieguito Union High School District.

Metagenomics is a primary tool for the description of microbial and viral communities. The sheer magnitude of the data generated in each metagenome makes identifying key differences in the function and taxonomy between communities difficult to elucidate. Here we discuss the application of seven different data mining and statistical analyses by comparing and contrasting the metabolic functions of 212 microbial metagenomes within and between 10 environments. Not all approaches are appropriate for all questions, and researchers should decide which approach addresses their questions.This work demonstrated the use of each approach: for example, random forests provided a robust and enlightening description of both the clustering of metagenomes and the metabolic processes that were important in separating microbial communities from different environments. All analyses identified that the presence of phage genes within the microbial community was a predictor of whether the microbial community was host-associated or free-living. Several analyses identified the subtle differences that occur with environments, such as those seen in different regions of the marine environment. © 2013 Dinsdale, Edwards, Bailey, Tuba, Akhter, McNair, Schmieder, Apkarian, Creek, Guan, Hernandez, Isaacs, Peterson, Reghand Ponomarenko.

Cancer and neurodegeneration represent the extreme responses of growing and terminally differentiated cells to cellular and genomic damage. The damage recognition mechanisms of nucleotide excision repair, epitomized by xeroderma pigmentosum (XP), and Cockayne syndrome (CS), lie at these extremes. Patients with mutations in the DDB2 and XPC damage recognition steps of global genome repair exhibit almost exclusively actinic skin cancer. Patients with mutations in the RNA pol II cofactors CSA and CSB, that regulate transcription coupled repair, exhibit developmental and neurological symptoms, but not cancer. The absence of skin cancer despite increased photosensitivity in CS implies that the DNA repair deficiency is not associated with increased ultraviolet (UV)-induced mutagenesis, unlike DNA repair deficiency in XP that leads to high levels of UV-induced mutagenesis. One attempt to explain the pathology of CS is to attribute genomic damage to endogenously generated reactive oxygen species (ROS). We show that inhibition of complex I of the mitochondria generates increased ROS, above an already elevated level in CSB cells, but without nuclear DNA damage. CSB, but not CSA, quenches ROS liberated from complex I by rotenone. Extracellular signaling by N-methyl-D-aspartic acid in neurons, however, generates ROS enzymatically through oxidase that does lead to oxidative damage to nuclear DNA. The pathology of CS may therefore be caused by impaired oxidative phosphorylation or nuclear damage from neurotransmitters, but without damage-specific mutagenesis. Environ. Mol.

The research focuses on the optimum operating condition of a semi dry reactor (SDR) and its design factors that ultimately affect the removal efficiency of acidic gases such as SO2, HCl and dioxin. The Study is conducted based on the analysis of Computational Fluid Dynamics model of SDR. In this study, a modeling of spray dry control system SDR was carried out for application to the municipal solid waste incineration system which is running in South Korea. The capacity of incinerator which used in this model is 200 tons per day. To find the optimum operating condition, variables that affect the removal efficiency were manipulated. The temperature profile, the gas profile and the pH profile of SDR were investigated. As of the parameters, the diameter of SDR was 5 meter and the height of SDR was 15.5 meter. The amount of inlet combustion gas of SDR was 12,000 Nm3/hr and the inlet temperature of SDR was 220°C. The amount of lime injection of SDR was 340 liter/hr. From the research, it was discovered that the change of the stoichiometry ratio of lime affected the temperature profile of the SDR. The gas velocity inside the main body of SDR ranged from 0.52 m/sec to 1.25 m/sec and the outlet gas velocity of SDR ranged from 6.8 to 7.5 m/sec. The average velocity in SDR was 0.65 m/sec, the average outlet gas velocity 7.3 m/sec, and the outlet gas temperature of SDR ranged from 175°C to 200°C. When the stoichiometric ratio was 1.0, 1.2, 1.5, the acidic gas removal was 38%, 45% and 56% respectively. Increasing the inlet gas amount increased the gas velocity and the pressure drop. The most pressure drop took place at the gas outlet duct.

This paper proposes a cost-effective approach to map and navigate an area with only the means of a single, lowresolution camera on a "smart robot," avoiding the cost and unreliability of radar/sonar systems. Implementation is divided into three main parts: object detection, autonomous movement, and mapping by spiraling inwards and using A* Pathfinding algorithm. Object detection is obtained by editing Horn-Schunck's optical flow algorithm to track pixel brightness factors to subsequent frames, producing outward vectors. These vectors are then focused on the objects using Sobel edge detection. Autonomous movement is achieved by finding the focus of expansion from those vectors and calculating time to collision which are then used to maneuver. Algorithms are programmed in MATLAB and implemented with LEGO Mindstorm NXT 2.0 robot for real-time testing with a low-resolution video camera. Through numerous trials and diversity of the situations, validity of results is ensured to autonomously navigate and map a room using solely optical inputs. ©2006-2012 Asian Research Publishing Network (ARPN).

We consider the design of vision-based control algorithms for unmanned aerial vehicles (UAVs), so as to enable a UAV to autonomously follow a person. A new vision-based control architecture is proposed with the goals of 1) robustly following the user and 2) implementing following behaviors programmed by manipulation of visual patterns. This is achieved within a detection/tracking paradigm, where the target is a programmable badge worn by the user. This badge contains a visual pattern with two components. The first is fixed and used to locate the user. The second is variable and implements a code used to program the UAV behavior. A biologically inspired tracking/recognition architecture, combining bottom-up and top-down saliency mechanisms, a novel image similarity measure, and an affine validation procedure, is proposed to detect the badge in the scene. The badge location is used by a control algorithm to adjust the UAV flight parameters so as to maintain the user in the center of the field of view. The detected badge is further analyzed to extract the visual code that commands the UAV behavior This is used to control the height and distance of the UAV relative to the user. © 2016 IEEE.
