Forty years ago, Viterbi published upper bounds on both the first error event (burst error) and bit error probabilities for Viterbi decoding of convolutional codes. These bounds were derived using a signal flow chart technique for convolutional encoders. In 1995, Best et al. published a formula for the exact bit error probability for Viterbi decoding of the rate R=1/2, memory m=1 convolutional enc
Using a mixed input–output model, this study examines potential changes in sector output and water requirements in Macedonia arising from climate change. By defining three climate change scenarios and exogenously specifying the warming shocks for five key agricultural sub-sectors, the effects on the economy were quantified. The results indicated that except for cereals and grapes, agricultural pro
This article addresses the temporality of resistance in the work context. We focus on the challenge of increasingly diminishing professional autonomy in higher education institutions as well as the vulnerability of staff subjected to academic managerialism. A case where a lecturer is exposed to the requirements to revise grading by senior administration is investigated. Power is understood from th
There is a never-ending quest for a stable economy with full employment and low inflation. Economists have suggested and policymakers have experimented with different fiscal and monetary policy regimes since at least the beginning of the industrial revolution. In this paper, we study Swedish stabilization policies through six policy regimes between 1873 and 2019. We focus on discretionary stabiliz
In this paper we introduce the notion of complex isoparametric functions on Riemannian manifolds. These are then employed to devise a general method for constructing proper r-harmonic functions. We then apply this to construct the first known explicit proper r-harmonic functions on the Lie group semidirect products Rm⋉ Rn and Rm⋉ H 2n+1, where H 2n+1 denotes the classical (2 n+ 1) -dimensional Hei
State-sponsored cyber groups have long utilized spear phishing to pierce government networks. Spear phishing relies on social engineering to trick individuals into revealing sensitive information or downloading malicious software, rather than hacking into a system vulnerability by force. While email remains the preferred medium to conduct spear phishing attacks, social m
Survival data for pancreatic cancer are usually based on actuarial calculations and actual long-term survival rates are rarely reported. Here we use population-level data from the Surveillance, Epidemiology, and End Results program for patients with microscopically confirmed pancreatic ductal adenocarcinoma diagnosed from 1975 to 2011. A total of 84,275 patients with at least 5 years of follow-up
This paper presents a numerical investigation of the ignition and combustion process of a primary reference fuel in a partially premixed light-duty internal combustion (PPC) engine. Partially pre-mixed combustion is achieved by employing a multiple injection strategy with three short injection events of fuel pulses. The timing of the first two fuel pulses, 48 and 22 crank angle degrees before top
Low temperature combustion (LTC), is a promising alternative for combustion engines, because it combines the positive aspects of both CI and SI engines, high efficiency and low emissions. Another positive aspect of LTC is that it can operate with gasoline of different octane ratings. Still, higher octane gasolines prove to be difficult to operate at low load conditions leading to high combustion i
Hemicellulose is the second largest polysaccharide group available in nature after cellulose. Hemicellulose is present in plant cell walls along with cellulose and lignin. It is an abundant and biodegradable material that could potentially replace fossil-based products. The focus of this thesis is the properties and valorization of softwood hemicellulose (galactoglucomannan).In the first part of t
Parents of children with disabilities may face higher labor-market penalties given the extra care and support required. Using Swedish administrative data, we focus on first-born children with Cerebral Palsy (CP) to estimate impacts on parental labor-market outcomes. We apply an event study approach to identify effects up to 10 years after the birth of the child. Our results show that employment an
Context. The bar pattern speed of the LMC has been computed based on data from Gaia DR3 using three different methods. One method suggested that the LMC might be hosting a bar that barely rotates, and is slightly counter-rotating with respect to the disc of the LMC, with a pattern speed of Ωp = −1.0 ± 0.5 km s−1 kpc−1. Aims. We aim to confirm that tidal interactions might prevent the bar hosted by
High-speed vertical In–Ga–As nanowire MOS field-effect transistor (MOSFET) measurements were analyzed through parametric layout models. Measurements from small and large transistors were used to fit dependencies on the number of gate fingers and the number of wires per finger. Extrapolations via intrinsic and parasitic elements reveal the optimal layout for peak frequency performance. To achieve a
How does new technology impact labor market outcomes? We address this question by examining the adoption of electricity in Sweden during the early 20th century. Leveraging detailed individual-level data that covers the entire labor market and exogenous variation in electricity access driven by proximity to hydro-power plants, we estimate the impact of electrification on individual labor market out
Background: Monitoring metabolites of tamoxifen, such as endoxifen, has been suggested as a strategy to ascertain therapeutic effect of tamoxifen therapy, but clinical guidelines are missing. Herein, we aim to investigate the outcome of endoxifen concentrations of low-dose tamoxifen, using change in mammographic breast density as a proxy for therapy response. Methods: In the randomized KARISMA-Tam
The interplay between angular momentum and particle number (which is the equivalent to the angular momentum in gauge space) is studied. The same technique that is used in the case of rotations in ordinary space can be used in gauge space for investigating the properties of individual quasiparticle levels and the total angular momentum of a nucleus. We study the isotopes of Dy and W, where a back-
The strategic role of communication practitioners has been discussedsince the 1970s. While it might not be surprising that managers andcoworkers view their roles as unclear, it is more surprising that commu-nication practitioners themselves also struggle with explaining theirstrategic roles and the value of their work. To elucidate the strategicwork of communication practitioners, we conducted a s
