MOCCA-Survey Database: extra galactic globular clusters – III. The population of black holes in Milky Way and Andromeda-like galaxies

This work investigates the black hole (BH) population of globular clusters (GCs) in Milky Way- and Andromeda-like galaxies. We combine the population synthesis code MASinGa and the MOCCA-Survey Database I to infer the properties of GCs harbouring a stellar-mass BH subsystem (BHS), an intermediate-mass BH (IMBH), or neither of those. We find that the typical number of GCs with a BHS, an IMBH, or

Astrophysics with the Laser Interferometer Space Antenna

The Laser Interferometer Space Antenna (LISA) will be a transformative experiment for gravitational wave astronomy, and, as such, it will offer unique opportunities to address many key astrophysical questions in a completely novel way. The synergy with ground-based and space-born instruments in the electromagnetic domain, by enabling multi-messenger observations, will add further to the discov

Intensive care photoplethysmogram datasets and machine-learning for blood pressure estimation: Generalization not guarantied

The large MIMIC waveform dataset, sourced from intensive care units, has been used extensively for the development of Photoplethysmography (PPG) based blood pressure (BP) estimation algorithms. Yet, because the data comes from patients in severe conditions-often under the effect of drugs-it is regularly noted that the relationship between BP and PPG signal characteristics may be anomalous, a claim

Ibuprofen delivery into and through the skin from novel oxidized cellulose-based gels and conventional topical formulations

The delivery of ibuprofen into and through the skin from novel formulations containing TEMPO-oxidized cellulose nanofibril-based (TOCN) gels was compared to that from two conventional and commercially available products. The gels were evaluated in-vitro (using both silicone membranes, and pig skin) and in-vivo in human volunteers. All gels showed consistent behaviour in a standard in vitro release

Liquid structure of the choline chloride-urea deep eutectic solvent (reline) from neutron diffraction and atomistic modelling

The liquid structure of the archetypal Deep Eutectic Solvent (DES) reline, a 1:2 molar mixture of choline chloride and urea, has been determined at 303 K. This is the first reported liquid-phase neutron diffraction experiment on a cholinium DES. H/D isotopic substitution is used to obtain differential neutron scattering cross sections, and an Empirical Potential Structure Refinement (EPSR) model i

Free-standing high surface area titania films grown at the air-water interface

Free-standing titania films were grown at the air-water interface, a novel method to synthesize robust TiO2 nanowire/nanoparticle composite films. The calcined films contain an anatase crystal phase and have a high surface area with a structure composed of one-dimensional long nanowires and mesoporous nanoparticle branches. These suggest a promising way to manufacture large areas of thick porous t

Use of the cyclic model in the description of local properties of composite crystalline oxides

Using cyclic boundary conditions and LCAO basis allows one to reproduce both band and local properties of the electronic structure of a crystal. Electronic structure of a row of composite copper and lead crystalline oxides are studied within the CNDO approximation, and the local properties (atomic charges, bond orders, valencies) are analyzed. A comparison of the local properties of some high-Tc s

SCA-LDPC: A Code-Based Framework for Key-Recovery Side-Channel Attacks on Post-Quantum Encryption Schemes

Whereas theoretical attacks on standardized crypto primitives rarely lead to actual practical attacks, the situation is different for side-channel attacks. Improvements in the performance of side-channel attacks are of utmost importance.In this paper, we propose a framework to be used in key-recovery side-channel attacks on CCA-secure post-quantum encryption schemes. The basic idea is to construct

Phonon and electron states in halogen-fullerene compounds

Study of phonon and electron subsystems of C60I4-x and C60Br24 crystals has shown a different character of chemical bonding in these materials: C60I4-x is a compound with weak van der Waals interaction between C-60 and I-2 molecules whereas C60Br24 is a covalent crystal with a charge transfer between nearest C and Br atoms.

Biomarkers of cellular aging during a controlled human malaria infection

Cellular aging is difficult to study in individuals with natural infection, given the diversity of symptom duration and clinical presentation, and the high interference of aging-related processes with host and environmental factors. To address this challenge, we took advantage of the controlled human malaria infection (CHMI) model. This approach allowed us to characterize the relationship among ce

Visual Language

Traditionally, research on human language has taken speech and written language as the only domains of investigation. However, there is now a wealth of empirical studies documenting visual aspects of language, ranging from rich studies of sign languages, which are self-contained visual language systems, to the field of gesture studies, which examines speech-associated gestures, facial expressions,

How melanism affects the sensitivity of lizards to climate change

The impact of climate change on global biodiversity is firmly established, but the differential effect of climate change on populations within the same species is rarely considered. In ectotherms, melanism (i.e. darker integument due to heavier deposition of melanin) can significantly influence thermoregulation, as dark individuals generally heat more and faster than bright ones. Therefore, darker

Reprogramming Cancer into Antigen Presenting Cells as a Novel Immunotherapy

Therapeutic cancer vaccination seeks to elicit activation of tumor-reactive T cells capable of recognizing tumor-associated antigens (TAAs) and eradicating malignant cells. Here, we present a cancer vaccination approach utilizing myeloid lineage reprogramming to directly convert cancer cells into tumor reprogrammed-antigen presenting cells (TR-APCs). Using syngeneic murine leukemia models, we demo

Mäns våld mot kvinnor - ett olösligt samhällsproblem? : Våld i svensk jämställdhetspolitik under 2000-talet

Under snart tre decennier har omfattande insatser genomförts för att få mäns våld mot kvinnor att upphöra, utan synbar effekt. Våldet tenderar snarare att öka. Varför tycks mäns våld mot kvinnor vara ett olösligt samhällsproblem? I denna rapport undersöker vi hur mäns våld mot kvinnor har hanterats i svensk politik de senaste 25 åren. Med utgångspunkt i offentligt tryck granskar vi den politiska r

Individually Fitting but Collectively Unfitting Blame

People that produce bad outcomes can thereby become the fitting targets of blame, the fitting intensity of which is determined by the badness of the outcomes. In the following paper, I suggest that the amount of blame instances that people are fitting targets of is also determined by the weight of the badness of the outcomes. I use the example of online blame as a paradigmatic case where the amoun
