Standard ZYMO DNA/RNA miniprep extraction protocol written in a user friendly way to reduce in-process-decisions and process time
A number of minimal problems of structure from motion for cameras with radial distortion have recently been studied and solved in some cases. These problems are known to be numerically very challenging and in several cases there were no practical algorithms yielding solutions in floating point arithmetic. We make some crucial observations concerning the floating point implementation of Gröbner bas
A low power wideband low noise amplifier (LNA) was designed and implemented in SiGe HBT technology. The measured noise figure is less than or equal to 1 dB in almost the entire L-band. The gain in the L-band is above 13 dB with a gain variation of 4 dB. Hence, it’s useful for present as well as future GNSS applications. The current consumption is 5 mA from a single supply of +5V. The stability of
The problem of correctly recovering assembly instructions from a binary has received much attention and both malware and license validation code often relies on various anti-disassembly techniques in order to complicate analysis. One well-known anti-disassembly technique is to use overlapping code such that the disassembler starts decoding from an incorrect byte, but still recovers valid code. The
We present a novel method for tracing reflected reading and multimodal learning, based on a combination of eye tracking and cued retrospective verbal protocols. With the help of this method, we can trace pupils’ problem solving, their integration of text, pictures and graphics, connect the process of reflected reading to the product (scores, learning outcomes) and uncover pupils' reading strategie
Vehicles in the future are anticipated to have the ability to communicate and exchange useful information in order to avoid collisions. However, for this cooperation to be possible all vehicles will have to be equipped with compatible wireless IEEE 802.11p modules that implement intelligent transport systems operating in the 5 GHz frequency band standard (ITS-G5 or WAVE). During the implementation
The advent of Java and similar languages on the real-time system scene necessitates the development of efficient strategies for scheduling the work of a garbage collector in a non-intrusive way. We propose a scheduling strategy, time-triggered garbage collection, based on assigning the collector a deadline for when it must complete its current cycle. We show that a time-triggered CC with fixed dea
Objective: To examine and compare the adult outcome in a representative sample of hospitalized adolescent-onset psychoses including occupational and social aspects. Method: A total of 81 patients with a first episode of early-onset psychosis (before age 19 years) presenting to the University Hospital of Lund, Sweden, between 1982 and 1993 were followed up an average of 10.5 years (range 5.1-18.2)
Currently, no ideal prostate cancer (PCa) diagnostic or prognostic test is available due to the lack of biomarkers with high sensitivity and specificity. There is an unmet medical need to develop combinations of multiple biomarkers which may have higher accuracy in detection of PCa and stratification of aggressive and indolent cancer patients. The aim of this study was to test two biomarker gene p
Quality requirements complement functional requirements with information on the target quality levels of software functions or emergent system quality aspects. In release planning the allocation of development effort in further investments into product enhancements, new or enhanced functions are competing with quality improvements for limited resources. When setting balanced quality targets for de
Phase-noise (PN) estimation and compensation are crucial in millimeter-wave (mmWave) communication systems to achieve high reliability. The PN estimation, however, suffers from high computational complexity due to its fundamental characteristics, such as spectral spreading and fast-varying fluctuations. In this paper, we propose a new framework for low-complexity PN compensation in orthogonal freq
In recent years two Swedish companies, Telia and Lundin Petroleum, have had to work hard to legitimate their actions as a result of allegations of criminal activity. In this paper, the corporate framings employed to deal with allegations of crime will be analysed on the basis of Stanley Cohen's (2009) theoretical work on processes of denial and neutralization techniques. More specifically, the pap
We present a new type of wireless access infrastructure consisting of a fabric of dispersed electronic circuits and antennas that collectively function as a massive, distributed antenna array. We have chosen to name this new wireless infrastructure 'RadioWeaves' and anticipate they can be integrated into indoor and outdoor walls, furniture, and other objects, rendering them a natural part of the e
The transition to a resource efficient economy that makes effective use of raw materials and energy is a multi-level dynamic process requiring a wide systems perspective. To operationalize this transition in a holistic manner, the concept of Circular Economy (CE) has been championed by major economies around the world. The idea with CE is to strive towards maximizing the utilization of products, c
We study planning problems where the transition function is described by a learned binarized neural network (BNN). Theoretically, we show that feasible planning with a learned BNN model is NP-complete, and present two new constraint programming models of this task as a mathematical optimization problem. Experimentally, we run solvers for constraint programming, weighted partial maximum satisfiabil
Vanuatu is one of the most hazard prone nations in the world and frequently tops the World Risk Report as the nation with the highest overall disaster risk. The devastation wrought by category 5 cyclone Pam (2015), the El Niño drought (2015/16), and volcanic eruptions in Ambae (2018), are but a few recent examples of disasters which have disrupted livelihoods and curtailed development. The Vanuatu
The digital cellular systems era started about thirty years ago with the release of the first digital cellphones. These first digital cellphones were very different from today’s slim and esthetic cellular pocket computers. They were not mass-produced in million units a day, and they were designed for radio performance rather than appearance. Today, all components are integrated inside the mobile p
A low-cost microstrip patch antenna array is proposed in this paper for automotive radar applications in ISM 24 GHz band. The elements of the center-fed array are connected in series to make a compact design with low complexity by obviating Wilkinson power divider. This approach also helps to reduce the dielectric losses of the array. A full-wave electromagnetics (EM) software EMPIRE XPU is used i
