Minimax filters for microphone arrays

Conventionally, minimax spatial/spectral filters for microphone arrays are designed by first discretizing the spatial and frequency domains into a finite number of grid points and then performing the optimization over these points. The drawback with this approach is that the response of the spatial/spectral filters in between the grid points can be poor. More recently, an approach that performs th

Telomere length, telomerase reverse transcriptase promoter mutations, and melanoma risk

Telomere repeats at chromosomal ends, critical for genomic integrity, undergo age-dependent attrition and telomere length has been associated with different disorders including cancers. In this study, based on 1469 patients and 1158 healthy controls, we show a statistically significant (P = 6 × 10-10 ) association between increased telomere length and melanoma risk. Mendelian randomization, using

A Devonian >2000-km-long dolerite dyke swarm-belt and associated basalts along the Urals-Novozemelian fold-belt : part of an East-European (Baltica) LIP tracing the Tuzo Superswell

Two dolerite dyke swarms are recognized along and paralleling the Ural Mountains, Russia. The Uralian swarm is 1400-km long (2300-km long if traced from its inferred plume centre). Further north, the Pay-Khoy swarm can be traced through the Pay-Khoy–Novaya Zemlya fold belt for a distance of c. 250 km (800-km long if traced from its inferred plume centre). An Upper Devonian age for volcanism associ

The impact of a DCV-system on the IAQ, energy use, and moisture safety in apartments - a case study

A novel DCV-system controls the air-change rate for each apartment in multifamily buildings based on two indoor air parameters: 1) the moisture load (supply), and 2) volatile organic compounds. With a central fan, but decentralized control boxes placed outside each apartment, the system controls the air-change rate for each apartment. This paper’s main aim is to determine the potential of this DCV

Investigating the dominant regions of the phase space associated with cc production relevant for the prompt atmospheric neutrino flux

A detailed mapping of the dominant kinematical domains contributing to the prompt atmospheric neutrino flux at high neutrino energies is presented by studying their sensitivity to the cuts on several kinematical variables crucial for charm production in cosmic ray scattering in the atmosphere. This includes the maximal center-of-mass energy for proton-proton scattering, the longitudinal momentum f

SparseJSR: A fast algorithm to compute joint spectral radius via sparse SOS decompositions

This paper focuses on the computation of the joint spectral radius (JSR), when the involved matrices are sparse. We provide a sparse variant of the procedure proposed by Parrilo and Jadbabaie to compute upper bounds of the JSR by means of sum-of-squares (SOS) programming. Our resulting iterative algorithm, called SparseJSR, is based on the term sparsity SOS (TSSOS) framework developed by Wang, Mag

Conformal minimal foliations on semi-Riemannian Lie groups

We study left-invariant foliations F on semi-Riemannian Lie groups G generated by a subgroup K. We are interested in such foliations which are conformal and with minimal leaves of codimension two. We classify such foliations F when the subgroup K is one of the important groups SU(2), SL_2(R), SU(2)*SU(2), SU(2)*SL_2(R)$, SU(2)*SO(2), SL_2(R)*SO(2). This way we construct new multi-dimensional famil

The impact of postoperative complications following cytoreductive surgery combined with oxaliplatin based heated intraperitoneal chemotherapy

Introduction: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS + HIPEC) has become the mainstream treatment for peritoneal metastases of colorectal origin. This extensive treatment is known for its increased morbidity rate. In this study, the impact of postoperative complications on survival was evaluated in a high-volume centre. Patients and method: Between November 2016

The validity of registered synchronous peritoneal metastases from colorectal cancer in the Danish medical registries

Introduction: Treatment options for peritoneal metastases (PM) from colorectal cancer (CRC) have increased, their efficiency should be monitored. For this purpose, register-based data on PM can be used, if valid. Purpose: We aimed to evaluate the completeness and positive predictive value (PPV) of synchronous peritoneal metastases (S-PM) registered among CRC patients in the Danish National Patient

A fast and sensitive method for the separation of carotenoids using ultra-high performance supercritical fluid chromatography-mass spectrometry

In this study, a rapid and sensitive ultra-high performance supercritical fluid chromatography-mass spectrometry (UHPSFC-MS) method has been developed and partially validated for the separation of carotenoids within less than 6 min. Six columns of orthogonal selectivity were examined, and the best separation was obtained by using a 1-aminoanthracene (1-AA) column. The length of polyene chain as we

Propionic acid production from glycerol in immobilized cell bioreactor using an acid-tolerant strain of Propionibacterium acidipropionici obtained by adaptive evolution

Propionic acid (PA) production from agro-industrial residues using propionibacteria has gained interest as an alternative to fossil-based process. Microbial production is however characterized by product inhibition, lowering the product titers and productivity. In this study, Propionibacterium acidipropionici DSMZ4900 was subjected to adaptive evolution to tolerate higher acid concentrations. The

On the Erasure-Correcting Capabilities of Low-Complexity Decoded LDPC Codes with Constituent Hamming Codes

Low-density parity-check (LDPC) codes can be constructed using constituent block codes other than single parity-check (SPC) codes. This paper considers random LDPC codes with constituent Hamming codes and investigates their asymptotic performance over the binary erasure channel. It is shown that there exist Hamming code-based LDPC codes which, when decoded with a low-complexity iterative algorithm

Leisure in Late Capitalism

There is no apparent need for individuals to endure this kind of suffering in contemporary Western society with all its advantages. Nevertheless, endurance running is now a mainstream leisure pursuit. Why do hundreds of thousands of men, women and even children choose this torturous kind of leisure activity?In previous literature on consumption of extraordinary experiences, authors focus on the pu

Energy scaling in a compact bulk multi-pass cell enabled by Laguerre-Gaussian single-vortex beams

We report pulse energy scaling enabled by the use of Laguerre-Gaussian single-vortex (LG0,l) beams for spectral broadening in a sub-40 cm long Herriott-type bulk multi-pass cell. Beams with orders l=1−3 are generated by a spatial light modulator, which facilitates rapid and precise reconfiguration of the experimental conditions. 180 fs pulses with 610 uJ pulse energy are post-compressed to 44 fs u

Brigatinib, an anaplastic lymphoma kinase inhibitor, abrogates activity and growth in ALK-positive neuroblastoma cells, Drosophila and mice

Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor which has been implicated in numerous solid and hematologic cancers. ALK mutations are reported in about 5-7% of neuroblastoma cases but the ALK-positive percentage increases significantly in the relapsed patient population. Crizotinib, the first clinically approved ALK inhibitor for the treatment of ALK-positive lung cancer has had le

Comparative Research into Recent Family and Partnership Formation and Dissolution Patterns in Nordic Countries: the case of Iceland

The current conjecture towards Nordic fertility rates brings the focus on the state of advancement of the second demographic transition (SDT) in the region. Nordic countries’ SDT developments have been unique as they have not experienced the same low fertility as other countries. Yet, since 2010, Iceland lost nearly a quarter of its fertility and reached an all-time low total fertility rate (TFR)

Ethanol Solvation in Water Studied on a Molecular Scale by Photoelectron Spectroscopy

Because of the amphiphilic properties of alcohols, hydrophobic hydration is important in the alcohol-water system. In the present paper we employ X-ray photoelectron spectroscopy (XPS) to investigate the bulk and surface molecular structure of ethanol-water mixtures from 0.2 to 95 mol %. The observed XPS binding energy splitting between the methyl C 1s and hydroxymethyl C 1s groups (BES-[CH3-CH2OH
