Spoken Language and Language Impairment in Deaf and Hard-of-Hearing Children: Fostering Classroom Environments for Mainstreamed Children

Despite medical, technical, and pedagogical advances, the risk for language impairment is still much higher in deaf and hard-of-hearing (DHH) children than in hearing peers. Research on linguistic, cognitive, and communicative development in DHH children has found a range of basic spoken language deficits. Twenty percent to 50% of deaf children still meet criteria for language impairment. Tests of

Abdominal pain after gastric bypass in the acute general surgical care setting

Background: Managing acute abdominal pain in the large and growing population of Roux-en-Y gastric bypass (RYGB)–operated patients poses a challenge to general surgeons, because of diagnostic limitations and the risk of internal herniation. Objective: To investigate the diagnoses, management, and outcome of RYGB patients admitted for acute abdominal pain. Setting: University Hospital, Sweden. Meth

Cause of death in autopsy-confirmed dementia disorders

Background and purpose: Dementia disorders predispose for lethal complications and decrease life expectancy. A more profound knowledge regarding end-stage conditions in dementia could therefore ameliorate treatment and care of these patients. Methods: Autopsy reports on 207 deceased individuals with clinically diagnosed neurocognitive disorder/dementia and on 200 neurocognitively healthy individua

A Cross-Sectional Cohort Study of Extended-Spectrum-Beta-Lactamase-Producing Enterobacterales in Patients with Traveler's Diarrhea

Patients with traveler’s diarrhea (TD) can acquire extended-spectrum-beta-lactamase (ESBL)-producing members of the Enterobacterales (EPE) during travel to areas of endemicity. The aim of the present study was to investigate the prevalence and characteristics of EPE carriage in travelers from southern Sweden who were sampled for bacterial diagnostics of TD compared to those of EPE carriage 10 year

Diverging responses to threats across generations in zooplankton

Our understanding on how organisms evolutionarily cope with simultaneously occurring, multiple threats over generations is still elusive. In a long-term experimental study, we therefore exposed clones of a freshwater cladoceran, Daphnia magna, to threats from predation and ultraviolet radiation (UVR) during three consecutive parthenogenetic generations. We show that Daphnia can adapt to different

Surface rheology and morphology of beer protein and iso-humulone at air-liquid surface

Foam is one of the unique properties of beer, but how the amphiphilic components stabilize the foam is still not fully understood. This study concerns the main surface active components. For this purpose, protein from barley and iso-humulone from hop, were extracted from raw materials separately to be able to consider their effect separately and in the controlled mixture. The layers were formed in

Does ‘flight shame’ affect social norms? Changing perspectives on the desirability of air travel in Germany

‘Flight shame’ describes an unease about the climate implications of air travel, and bears evidence of a change in social norms that have so far associated flying with social status. This paper discusses whether Fridays for Future demonstrations and ensuing flight shame have influenced social norms regarding the desirability of air travel, and whether this is measurable in a decline in air travel,

SMIM1, carrier of the Vel blood group, is a tail-anchored transmembrane protein and readily forms homodimers in a cell-free system

Antibodies to the Vel blood group antigen can cause adverse hemolytic reactions unless Vel-negative blood units are transfused. Since the genetic background of Vel-negativity was discovered in 2013, DNA-based typing of the 17-bp deletion causing the phenotype has facilitated identification of Vel-negative blood donors. SMIM1, the gene underlying Vel, encodes a 78-amino acid erythroid transmembrane

Feature size control using surface reconstruction temperature in block copolymer lithography for InAs nanowire growth

Here we present a method to control the size of the openings in hexagonally organized BCP thin films of poly(styrene)-block-poly(4-vinylpyridine) (PS-b-P4VP) by using surface reconstruction. The surface reconstruction is based on selective swelling of the P4VP block in ethanol, and its extraction to the surface of the film, resulting in pores upon drying. We found that the BCP pore diameter increa

Compressively-strained GaSb nanowires with core-shell heterostructures

GaSb-based nanowires in a gate-all-around geometry are good candidates for binary p-type transistors, however they require the introduction of compressive strain to enhance the transport properties. Here, we for the first time demonstrate epitaxial GaSb-GaAsxSb1−x core-shell nanowires with a compressively strained core. Both axial and hydrostatic strain in GaSb core have been measured by X-ray dif

The Four-Kallikrein Panel Is Effective in Identifying Aggressive Prostate Cancer in a Multiethnic Population

BACKGROUND: The four-kallikrein (4K) panel has been demonstrated to improve prediction of aggressive prostate cancer compared with prostate-specific antigen (PSA) among men with moderately elevated PSA levels. However, the development and testing of the 4K panel has been conducted primarily in White men, with limited data in African Americans and no studies in other racial and ethnic groups. METHO

Controlling photoionization using attosecond time-slit interferences

When small quantum systems, atoms or molecules, absorb a high-energy photon, electrons are emitted with a well-defined energy and a highly symmetric angular distribution, ruled by energy quantization and parity conservation. These rules are based on approximations and symmetries which may break down when atoms are exposed to ultrashort and intense optical pulses. This raises the question of their

Decreased prevalence of Moraxella catarrhalis in addition to Streptococcus pneumoniae in children with upper respiratory tract infection after introduction of conjugated pneumococcal vaccine : a retrospective cohort study

Objectives: To study effects of the introduction of pneumococcal conjugate vaccines (PCV) on the interspecies dynamics of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis in preschool children with respiratory tract infection. Methods: Nasopharyngeal samples from children aged ≤6 years with upper respiratory tract infection (n = 14 473) in South Sweden were analysed durin

Effects of traps in the gate stack on the small-signal RF response of III-V nanowire MOSFETs

We present a detailed study of the effect of gate-oxide-related defects (traps) on the small-signal radio frequency (RF) response of III-V nanowire MOSFETs and find that the effects are clearly identifiable in the measured admittance parameters and in important design parameters such as h21 (forward current gain) and MSG (maximum stable gain). We include the identified effects in a small-signal mo

Vertical nanowire III–V MOSFETs with improved high-frequency gain

High-frequency performance of vertical InAs/InGaAs heterostructure nanowire MOSFETs on Si is demonstrated for the first time for a gate-last configuration. The device architecture allows highly asymmetric capacitances, which increases the power gain. A device with Lg = 120 nm demonstrates fT = 120 GHz, fmax = 130 GHz and maximum stable gain (MSG) = 14.4 dB at 20 GHz. These metrics demonstrate the

Brief Report : Interferon-γ-Inducible Protein 10-A Potential Marker for Targeted Viral Load Monitoring of Antiretroviral Treatment?

BACKGROUND: The use of surrogate markers for targeting viral load (VL) testing could be an alternative to universal VL testing during antiretroviral treatment (ART) and would allow for more effective resource allocation. We investigated the correlation between levels of HIV RNA and interferon-γ-inducible protein 10 (IP-10) in Ethiopian adults at 12 months after ART initiation. In addition, we spec

Explicationist Epistemology and the Explanatory Role of Knowledge

It has been argued that much of contemporary epistemology can be unified under Carnap’s methodology of explication, which originated in the neighboring field of philosophy of science. However, it is unclear to what extent epistemological theories that emphasize the explanatory role of knowledge fit into this picture, Kornblith’s natural kind epistemology and Williamson’s knowledge first approach b

Metformin Prescription Associated with Reduced Abdominal Aortic Aneurysm Growth Rate and Reduced Chemokine Expression in a Swedish Cohort

Background: Recent reports suggest that the negative association between diabetes mellitus and abdominal aortic aneurysm (AAA) may be driven by metformin, the world's most common antidiabetic drug rather than diabetes per se. We sought to investigate the association among AAA growth rate, chemokine profile, and metformin prescription in a contemporary Swedish cohort. Methods: Patients under survei

Thermal Stability of Single-Crystalline IrO2(110) Layers : Spectroscopic and Adsorption Studies

The interaction of ultrathin single-crystalline IrO2(110) films with the gas phase proceeds via the coordinatively unsaturated sites (cus), in particular Ircus, the undercoordinated oxygen species on-top O (Oot) that are coordinated to Ircus, and bridging O (Obr). With the combination of different experimental techniques, such as thermal desorption spectroscopy, scanning tunneling microscopy (STM)
