NoteAbout the Concept of “Net Multipliers”
2002
Net multipliers, as introduced by Oosterhaven and Stelder (2002) accept outputs as entries instead of final demand. They are found by multiplying ordinary multipliers by the final demand ratio over the sector’s output. This pragmatic solution suffers from ratio instability over time. The alternative net multipliers proposed here are based on the interpretation of the Leontief inverse matrix for the effects generated at each round. The new solution is not sensitive to the size of impacts. Now net multiplier is equal to the corresponding ordinary multiplier minus one, and the ordering of multipliers is unchanged.
Pharmacological Neuroenhancement: Substances and Epidemiology
2013
Pharmacological neuroenhancement (PN) refers to the general use of psychoactive substances with the purpose of cognitive enhancement (e.g. enhancement of vigilance, concentration, memory or mood) by healthy subjects. Substances for PN include Over-the-Counter- (OTC-) substances such as coffee, caffeinated drinks/energy drinks, caffeine tablets and Ginkgo biloba as well as prescription drugs and illicit drugs (e.g. (psycho-) stimulants). “Brain doping” refers to the illicit use of a subcategory of these substances. On the one hand, this subcategory includes prescription drugs for the treatment of attention deficit/hyperactivity disorder (ADHD), sleep disorders, Alzheimer’s disease and depres…
Multiple modular very long instruction word processors based on field programmable gate arrays
2007
Modern field programmable gate array (FPGA) chips, with their large memory capacity and reconfigurability potential, are opening new frontiers in rapid prototyping of embedded systems. With the advent of high-density FPGAs, it is now possible to implement a high-performance very long instruction word (VLIW) processor core in an FPGA. This paper describes research results about enabling the DSP TMS320 C6201 model for real-time image processing applications by exploiting FPGA technology. We present a modular DSP C6201 VHDL model with a variable instruction set. We call this new development a minimum mandatory modules (M3) approach. Our goals are to keep the flexibility of DSP in order to shor…
High-speed, low-complexity fir filter using multiplier block reduction and polyphase decomposition
2005
In this paper we discuss the design and implementation of a highspeed FIR filter for both interpolation and decimation of the sample frequency. Several FIR filter structures are compared and various schemes for simplifying the implementation of the multiplications are evaluated. Carry-save adders with carryoverflow correction are used in the implementation. The results in terms of chip area and power consumption are compared using a standard 0.8 pm 3.3 V CMOS process.
TID and SEE Tests of an Advanced 8 Gbit NAND-Flash Memory
2008
We report on the dose and operational mode dependence of error percentage, stand-by current, erase and write time of 8 Gbit / 4 Gbit NAND-flash memories as well as on their static, dynamic and SEFI cross sections.
Pileup and underlying event mitigation with iterative constituent subtraction
2019
Abstract The hard-scatter processes in hadronic collisions are often largely contaminated with soft background coming from pileup in proton-proton collisions, or underlying event in heavy-ion collisions. This paper presents a new background subtraction method for jets and event observables (such as missing transverse energy) which is based on the previously published Constituent Subtraction algorithm. The new subtraction method, called Iterative Constituent Subtraction, applies event-wide implementation of Constituent Subtraction iteratively in order to fully equilibrate the background subtraction across the entire event. Besides documenting the new method, we provide guidelines for setting…
Concatenated logic functions using nanofluidic diodes with all-electrical inputs and outputs
2018
[EN] Nanopore-based logical schemes in ionic solutions typically involve single gates and chemical inputs. The design of computer-like functions requires the consecutive concatenation of several gates and the use of electrical potentials and currents to facilitate the downstream transfer of electrochemical information. We have demonstrated the robust operation of concatenated logic functions using biomimetic nanofluidic diodes based on single pore membranes. To this end, we have implemented first the logic functions AND and OR with combinations of single nanopores using all-electrical input and output signals. The concatenation of these gates allows the output of the OR gate to act as one o…
Cross-lagged associations between perceived external employability, job insecurity, and exhaustion: Testing gain and loss spirals according to the Co…
2012
Summary This study investigates perceived external employability (PEE) as a personal resource in relation to job insecurity and exhaustion. We advance the idea that PEE may reduce feelings of job insecurity and, through felt job insecurity, also exhaustion. That is, we probe the paths from PEE to job insecurity and from job insecurity to exhaustion. We furthermore account for possible reversed causality, so that exhaustion felt job insecurity and felt job insecurity PEE. This aligns with insights from the Conservation of Resources Theory, which is built on the assumption of resource caravans passageways and associated gain and loss spirals. We based the results on a sample of 1314 workers…
Pēcstundas diskusija dabaszinātņu skolotāja refleksijas prasmes pilnveidei
2016
PĒCSTUNDAS DISKUSIJA DABASZINĀTŅU SKOLOTĀJA REFLEKSIJAS PILNVEIDEI. D. Sarceviča-Kalviške, zinātniskā vadītāja Dr. paed. Dace Namsone. Maģistra darbs, 83 lappuses, 9 attēli, 3 tabulas, 45 literatūras avoti, 12 pielikumi. Latviešu valodā. Refleksijas prasme ir būtiska skolotāja profesionālajā darbībā, lai skolotājs objektīvi izvērtētu savu pieredzi, izdarītu secinājumus un balstītu tajos savu tālāko darbību. Pēcstundas diskusija ir viena no metodēm, lai veicinātu refleksijas prasmes pilnveidi, tomēr trūkst pētījumu, kas atklātu pēcstundas diskusijas lomu saistībā ar dažāda līmeņa refleksijas prasmi, kā arī pēcstundas diskusijas vadītāja darbību lomu tajā. Gadījuma pētījuma ietvaros veikta di…
La productividad científica en drogodependencias desde las revistas específicas
2011
From general population surveys and specific studies data, an epidemiological description is offered. Since 1994, the year of the fi rst Spanish school survey, until 2008, in all temporal references alcohol use trend was slightly decreasing for both boys and girls, though less for girls that showed somewhat higher prevalences in recent years. Drunkenness prevalence trend among those students drinking alcohol during the last 30 days has increased and was higher for boys. For cannabis and cocaine there was an increasing trend until 2004; trends for ecstasy and hallucinogens were less marked towards lower prevalences in recent years; all of them were higher in boys. Girls had higher prevalence…
