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

Purpose: To evaluate the correlation between problematic social media use, alcohol use disorder, and smoking addiction through both cigarettes and waterpipe, among a sample of Lebanese adults. Methods: This cross-sectional study was carried out between January and April 2019. It enrolled 461 residents of the community randomly selected from Lebanon's districts in a proportionate rate. Results: Hig

In the last decades, the substantial technical progress in radiation oncology offered the opportunity for more accurate planning and delivery of treatment. At the same time, the evolution of systemic treatment and the advent of modern diagnostic tools allowed for more accurate staging and consequently a safe reduction of radiotherapy (RT) target volumes and RT doses in the treatment of lymphomas.

Objective: To determine predictors of change in neuropsychiatric (NP) event status in a large, prospective, international inception cohort of patients with systemic lupus erythematosus (SLE). Methods: Upon enrollment and annually thereafter, NP events attributed to SLE and non-SLE causes and physician-determined resolution were documented. Factors potentially associated with the onset and resoluti

While much of the literature on complex global environments builds on studies of multinationals from mature markets, little is known about how firms from emerging markets understand and cope with complexity. This paper builds on a longitudinal case study of Zhejiang Geely Holding Group (ZGH) in the post-acquisition process of Volvo Car Group (VCG) and its efforts to learn how to learn in order to

The Swedish Model on the labor market has been celebrated as a way to combine mobility with low unemployment and small wage gaps. As part of the model, relocation allowances were pioneered from the late 1950s. The program expanded thereafter and as much as 1% of the population in the high-unemployment north moved with assistance in the 1960s. Today, migration incentives are discussed to address pr

Landscapes play an important role in many areas of biology, in which biological lives are deeply entangled. Here we discuss a form of landscape in evolutionary biology which takes into account (1) initial growth rates, (2) mutation rates, (3) resource consumption by organisms, and (4) cyclic changes in the resources with time. The long-term equilibrium number of surviving organisms as a function o

Background: The impact of body mass index (BMI) on mortality varies with age and disease states. The aim of this research study was to analyse the associations between BMI categories and short- and long-term mortality in patients with or without diabetes seeking care at the emergency department (ED) with acute dyspnoea. Population and methods: Patients aged ≥18 years at ED during daytime on weekda

This paper is concerned with the management of multi-plant manufacturing networks. Two key concepts in this domain are plant roles and plant autonomy in the context of operations strategy decision-making. We investigate the relationship between these two concepts and their impact on plant performance. We use data from 102 manufacturing plants belonging to multi-plant networks. The results suggest

In this paper we present a technique that improves rendering performance for real-time ith ray in the presence of dynamic lights and objects. In particular we verify photon paths from the previous frame against dynamic objects in the current frame, and show how most photon paths are still valid. When using area lights, we use a data structure to store light distribution that tracks light paths all

This study aims to understand how goals of activation and gender equality interact in labor market programs directed towards activating unemployed participants. The study draws on interviews with 28 social workers and managers at four Swedish municipally governed labor market programs typically targeted towards poor, unemployed individuals with little to no attachment to the labor market or social

This paper presents the numerical study of soot formation and oxidation processes across different ambient temperatures (900K, 1000K, and 1100K) and oxygen levels (15% and 21% O2) using large eddy simulation coupled with a two-equation soot model. The predicted ignition delay time, lift-off length and soot distribution show good agreements with the corresponding experimental data. A stronger oxida

Background: Deep Brain Stimulation (DBS) is an established treatment for motor symptoms in Parkinson's disease (PD). However, side effects often limit the usefulness of the treatment. New method: To mitigate this problem, we developed a novel cluster of ultrathin platinum-iridium microelectrodes (n = 16) embedded in a needle shaped gelatin vehicle. In an established rodent PD-model (6-OHDA unilate

Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution

Welding fumes induce lung toxicity and are carcinogenic to humans but the molecular mechanisms have yet to be clarified. The aim of this study was to evaluate the toxicity of stainless and mild steel particles generated via gas–metal arc welding using primary human small airway epithelial cells (hSAEC) and ToxTracker reporter murine stem cells, which track activation of six cancer-related pathways

Quinoa (Chenopodium Quinoa Willd.), a South American grain, has great potential for innovation and development of improved food products because of its protein content and nutritional benefits. The study aimed to develop an instant-mix beverage based on fermented quinoa with reduced phytate content and viable lactic bacteria. Two different lactic fermentation processes were designed known as Ferme

To counteract global food safety hazards related to raw consumption of ready-to-eat leafy vegetables, a method to improve bacterial status using antagonistic bacteria was studied under field conditions. This is the first study to identify potential Escherichia coli antagonists from the native microbiota on leafy green vegetables and evaluate their effect in an industrial field production setting.

This brief overview of the use of household salt (NaCl) in optically stimulated luminescence (OSL) dosimetry is focusing on the use of NaCl pellets. It is suggested that the most optimal use of household NaCl, in general prospective dosimetry, is to compress the salt grains to pellets and read the radiation induced signal using OSL rather than TL. A summary of the main OSL dosimetric properties is

Recent interest in applying novel imaging techniques to infer optical resolution in compound eyes underscores the difficulty of obtaining direct measures of acuity. A widely used technique exploits the principal pseudopupil, a dark spot on the eye surface representing the ommatidial gaze direction and the number of detector units (ommatidia) viewing that gaze direction. However, dark-pigmented eye
