Analysing Resilience Indicator Traits in Austrian Fleckvieh, Brown Swiss and Holstein‐Friesian Cattle
1 Introduction Throughout their lifespan, livestock are subjected to a variety of intrinsic and extrinsic stressors. In dairy cows, these include management practices and negative energy balance during early lactation (Mekuriaw 2023), problems arising from climate change, such as fluctuations in feed and water availability (Vaiknoras et al. 2024), emerging diseases and heat stress (Bett et al. 2017).

Broken-symmetry magnetic phases in two-dimensional triangulene crystals
We provide a comprehensive theory of magnetic phases in two-dimensional triangulene crystals, using both Hubbard model and density functional theory (DFT) calculations. We consider centrosymmetric and noncentrosymmetric triangulene crystals. In all cases DFT and the mean-field Hubbard model predict the emergence of broken-symmetry antiferromagnetic (ferrimagnetic) phases for the centrosymmetric (noncentrosymmetric) crystals.

Strong magnetic proximity effect in van der Waals heterostructures driven by direct hybridization
We propose another class of magnetic proximity effects based on the spin-dependent hybridization between the electronic states at the Fermi energy in a nonmagnetic conductor and the narrow spin-split bands of a ferromagnetic insulator. Unlike conventional exchange proximity, we show this hybridization proximity effect has a very strong influence on the nonmagnetic layer and can be further modulated by application of an electric field.

Nonperturbative indirect exchange in spin valley coupled two-dimensional crystals
We study indirect exchange interactions between localized spins of magnetic impurities in spin valley coupled systems described with the Kane-Mele model. Our model captures the main ingredients of the energy bands of the 1H transition metal dichalcogenide (TMD) monolayers, such as 1H−MoS2 and 1H−NbSe2. To obtain the effective interactions, we use the exact diagonalization of the Hamiltonian, avoiding momentum cutoffs.
How animal milk and plant-based alternatives diverge in terms of fatty acid, amino acid, and mineral composition - npj Science of Food
Abstract The decline in fresh milk in the Western world has in part been substituted by an increased consumption of plant-based beverages (PBB). These are often marketed as healthy and sustainable alternatives to milk and dairy foodstuff, although studies have suggested PBB to be of lower nutrient quality.

Under a Creative Commons license open access Keywords Paleolake succession Drilling core Paleoclimate changes Tephrochronology Electrical resistivity tomography 1. Introduction Lake sediments hosted in volcanic craters provide continuous sedimentary successions ideal for multi-proxy paleoclimatic and paleoenvironmental studies (e.g., Mingram et al., 2004; Brauer et al., 2007; White and Ross, 2011; Marchetto et al., 2015; Lacey et al., 2015; Chu et al., 2014; Wu et al., 2019 for review).
Sign reversal of the Josephson inductance magnetochiral anisotropy and 0–π-like transitions in supercurrent diodes - Nature Nanotechnology
Abstract The recent discovery of the intrinsic supercurrent diode effect, and its prompt observation in a rich variety of systems, has shown that non-reciprocal supercurrents naturally emerge when both space-inversion and time-inversion symmetries are broken. In Josephson junctions, non-reciprocal supercurrent can be conveniently described in terms of spin-split Andreev states.
Un hombre muere atropellado cuando ayudaba a una familia de patos a cruzar la calle
Cada día hay noticias tristes y conmovedoras, y luego está la que acontece en las siguientes líneas. Casey Rivara circulaba el jueves pasado por las calles de Rocklin, en California (Estados Unidos) como un día cualquiera. No iba solo, había recogido a sus dos hijos de las clases de natación. De camino a casa, la familia vio a "una mamá pato con sus patitos intentando cruzar una intersección concurrida", explican los familiares del hombre.

Introduction and aims of the study: 1p36 deletion syndrome is the most common terminal deletion in humans, occurring in 1:5000 births, predominantly on females. Most cases are sporadic; a minority is associated with chromosomal duplication. Clinical features include craniofacial dysmorphisms, hypotonia, development delay, epilepsy, hearing loss and also cardiac, cerebral, visual, skeletal and urogenital anomalies.
201 Trisomy 2 mosaicism as a rare cause of a polymalformed foetus
Introduction and aims of the study: Trisomy 2 mosaicism (T2M) is a chromosome disorder characterized by having an extra copy of chromosome 2 in a variable proportion of a patient’s cells. Case-reports described in the literature are scarce and the phenotype associated with this disorder is not well known, since most cases result in miscarriage.
61 Arabin pessary: 5 Years experience of a terciary hospital
Introduction: Preterm labor is the leading cause of perinatal morbimortality and has a significant socioeconomic impact. Preterm labor can be classified as early (< 28 weeks), intermediate (28-32 weeks) and late (32-37 weeks). Risk factors associated with preterm labor include African women, smoking, previous late abortion and/or preterm labor, cervix interventions, multiple pregnancy, short cervix and urinary and/or vaginal infections.
203 Off-label use of femostop® to treat postpartum haemorrhage
Introduction and aims of the study: Postpartum haemorrhage (PPH) is the leading cause of maternal death worldwide. The most common cause is uterine atony (UA), where the uterus is unable to contract properly. All therapeutic measures are based on the same principle which is uterine contraction stimulation. FemoStop® was developed for femoral artery/vein compression after percutaneous endovascular interventions and has proven to be reliable in achieving hemostasis in this context.
15 Victoria: A case of obstetric success
Hypertensive disorders of pregnancy constitute one of the leading causes of maternal and perinatal mortality worldwide. These disorders increase the risk of placental abruption, amongst others, an obstetric emergency that requires lifesaving procedures.
Introduction and aims of the study: Acute pulmonary edema is a rare complication in pregnancy and postpartum, with an estimated incidence between 0.08 and 0.5%. Acute pulmonary edema is the main cardiovascular complication of preeclampsia and one of the criteria of severe preeclampsia; occurs in 3% of preeclampsia cases, 70% of which take place during postpartum. The main risk factors for acute pulmonary edema in preeclampsia are advanced maternal age, multiparity and chronic hypertension.
PRUEBA BMW M5 CS: MUCHO MÁS QUE MARKETING

Prueba Audi RS 6 Avant C8: Sin perder la referencia
Que en 8000vueltas tenemos una debilidad latente por los Audi RS y particularmente por sus rancheras no es una novedad. En el equipo incluso tenemos compañeros que siguen usando su RS 4 B7 como coche de diario, ajenos a cualquier tipo de recomendación que desde los estamentos oficiales dictan como socialmente aceptable. Arrancar ese V8 por la mañana y hacer retumbar nuestros pisos hipotecas es un auténtico lujo.
Association between sedentary behavior and bone mass in adolescents
Abstract Summary The effects of sedentary behavior on adolescents’ bone health are controversial because, even in normal weight individuals, the excessive time spent in some specific types of these behaviors appears to have no negative effect on bone health. Purpose To analyze the relationship between sedentary behaviors and bone mass in adolescents. Methods One hundred four adolescent boys and girls, aged 10 to 14 years, were divided into normal weight and overweight according to weight status.

Anak Krakatau triggers volcanic freezer in the upper troposphere
Abstract Volcanic activity occurring in tropical moist atmospheres can promote deep convection and trigger volcanic thunderstorms. These phenomena, however, are rarely observed to last continuously for more than a day and so insights into the dynamics, microphysics and electrification processes are limited. Here we present a multidisciplinary study on an extreme case, where volcanically-triggered deep convection lasted for six days.
Combined Flow Abstraction and Climate Change Impacts on an Aggrading Alpine River
Recent climatic warming and associated glacial retreat may have a large impact on sediment release and transfer in Alpine river basins. Concurrently, the sediment transport capacity of many European Alpine streams is affected by hydropower exploitation, notably where flow is abstracted but the sediment supply downstream is maintained. Here, we investigate the combined effects of climate change and flow abstraction on morphodynamics and sediment transfer in the Borgne River, Switzerland.

Murine melanoma cells incomplete reprogramming using non-viral vector
The reprogramming of cancer cells into induced pluripotent stem cells or less aggressive cancer cells can provide a modern platform to study cancer-related genes and their interactions with cell environment before and after reprogramming. Herein, we aimed to investigate the reprogramming capacity of murine melanoma B16F10 cells.
3rd ESO-ESMO International Consensus Guidelines for Advanced Breast Cancer (ABC 3)
Advanced Breast Cancer (ABC) comprises both locally advanced (LABC) and metastatic breast cancer (MBC) [1]. Although treatable, MBC remains an incurable disease with a median overall survival of ?2–3 years and a 5-year survival of only ?25% [2–4]. Some more recent series seem to indicate an improvement in median overall survival [5, 6].
Equity-focused health impact assessment of Portuguese tobacco control legislation
The World Health Organization recommend the Equity-Focused Health Impact Assessment (HIA) as a means to assess the impact of social and economic policies on the health of populations, and acknowledges their contribution to health inequality. We describe the application of the Equity-focused Impact Assessment methodology on the Portuguese law on Smoking Prevention and Tobacco Control (Law No. 37/2007).
ESO-ESMO 2nd international consensus guidelines for advanced breast cancer (ABC2)
Advanced breast cancer (ABC) is a treatable but still generally incurable disease. The goals of care are to optimize both length and quality of life. Due to continuous research, several advances have been made, particularly for the human epidermal growth factor receptor 2 (HER-2)-positive and for luminal-like subtypes.
