description: We consider the use of polarization properties as a means to discriminate between Synchrotron Self-Absorption (SSA) and Free--Free Absorption (FFA) in GHz-Peaked Spectrum (GPS) sources. The polarization position angle (PA) of synchrotron radiation at high frequencies for the optically thin regime is perpendicular to the magnetic field, whereas it is parallel to the magnetic field at low frequencies for the optically thick regime. Therefore, SSA produces a change in PA of $90^{\circ}$ across the spectral peak, while FFA does not result in such a change. We analyzed polarization data from VLA observations for six GPS sources to see if such a change in PA was present. Our results indicate that there is no significant evidence for $90^{\circ}$ change in PA across the spectral peak, suggesting that FFA is more likely than SSA for low-frequency cutoffs in these sources.

description: Laser wakefield acceleration (LWFA) using high repetition rate mJ-class laser systems brings unique opportunities for a broad range of applications. In order to meet the conditions required for the electron acceleration with lasers operating at lower energies, one has to use high density plasmas and ultrashort pulses. In the case of a few-cycle pulse, the dispersion and the carrier envelope phase effects can no longer be neglected. In this work, the properties of the wake waves generated by ultrashort pulse lasers in near-critical density plasmas are investigated. The results obtained may lead to enhancement of the quality of LWFA electron beams using kHz laser systems.

description: Significant investment and development have gone into integrating Artificial Intelligence (AI) in medical and healthcare applications, leading to advanced control systems in medical technology. However, the opacity of AI systems raises concerns about essential characteristics needed in such sensitive applications, like transparency and trustworthiness. Our study addresses these concerns by investigating a process for selecting the most adequate Explainable AI (XAI) methods to comply with the explanation requirements of key EU regulations in the context of smart bioelectronics for medical devices. The adopted methodology starts with categorising smart devices by their control mechanisms (open-loop, closed-loop, and semi-closed-loop systems) and delving into their technology. Then, we analyse these regulations to define their explainability requirements for the various devices and related goals. Simultaneously, we classify XAI methods by their explanatory objectives. This allows for matching legal explainability requirements with XAI explanatory goals and determining the suitable XAI algorithms for achieving them. Our findings provide a nuanced understanding of which XAI algorithms align better with EU regulations for different types of medical devices. We demonstrate this through practical case studies on different neural implants, from chronic disease management to advanced prosthetics. This study fills a crucial gap in aligning XAI applications in bioelectronics with stringent provisions of EU regulations. It provides a practical framework for developers and researchers, ensuring their AI innovations advance healthcare technology and adhere to legal and ethical standards.

description: Background: Blunt abdominal trauma (BAT) is very common, the prevalence being 12–15%. Evaluation of patients with BAT is a challenge. This study aimed to compare the USG & CT with regards the frequency of correct findings in the detection of solid intra-abdominal injuries. Objectives: To determine the frequency of correct findings of abdominal ultrasonography compared with CT scan in the detection of solid intra-abdominal visceral injuries. Methods: The study was carried out at Radiology Department Nishtar Hospital, Multan & Children Hospital Multan, Pakistan, for a duration of six months with Eighty-eight patients selected using non-probability purposive sampling technique. Results: Mean age of the patients was 35.83±14.02 years. There were 75(85.2%) male and 13(14.8%) female in the present study, respectively. Ultrasonography detected abdominal injury in 49(55.7%) patients while it was detected in 59(67%) patients by computed tomography scan. Abdominal injury detected by both ultrasonography and computed tomography was 48 patients (true positive). Ultrasound sensitivity was revealed 81.36%, specificity 96.55%, diagnostic accuracy 86.36%, Positive predictive value 97.95%, and Negative predictive value 71.79%. Conclusion: CT scan is the gold standard modality for blunt abdominal trauma, whereas ultrasound can be used as the first-line modality in the patients of blunt abdominal trauma.

description: The sensitivity of future gravitational wave interferometers is expected to be limited through-out the detection band by quantum vacuum fluctuations, which can be reduced by quantum non-demolition methods such as squeezed vacuum injection. However, optical losses in the readout chainseverely limit the effectiveness of such schemes. We propose an optomechanical device to be installedat the output of the detector that mitigates the effect of readout loss, thus allowing the detector tobetter exploit quantum noise evasion schemes.
GAMMA-RAY AND NEUTRINO DIFFUSE EMISSIONS OF THE MILKY-WAY: WHAT DO THEY IMPLY ?

description: Parallel Talk presented at the XX International Workshop on Neutrino Telescopes - Venice 23-27 October 2023

 

Abstract:

In this talk we will focus on the γ-ray and neutrino diffuse emissions of the Galaxy which recently has been both observed up to the PeV. One of the main aims of these measurements is to understand the origin and the propagation of Galactic cosmic-rays. In this framework, it is striking that the γ-ray diffusion emissions measured by LHAASO has been found more intense and harder than predicted by conventional cosmic-ray propagation models as it was also found — less prominently — at lower energies. The possible forthcoming discovery of the neutrino counterpart of such emission would imply its hadronic origin hence disfavouring unresolved leptonic sources, as pulsars and TeV halos, to be responsible of such an excess. We will show that a physically motivated cosmic-ray propagation scenario featuring non-homogeneous transport, which has been developed over the latest years to reproduce γ-ray observations in different regions of the Galaxy, provides a consistent description of γ-ray and neutrino measurements up to the PeV as well as high energy cosmic ray data beyond that energy.

description: A product is a bundle of internal-external attributes concurring to satisfy the consumer's physiological and psychological needs, these last ones growing in the ranking of consumer's preferences for the higher education and better income achieved in the present socio-economic environment. The progresses occurred in the food industry and strategies of the distribution may have affected the perceptions about food products, affecting the preference order. For typical products the question is if they are still appreciated for their intrinsic quality or better perceived for the intangible values of tradition, artisan style, cultural, historical or ethnological values, geographic location and others. Social and cultural changes may have affected the consumer's preferences for safety, hygienic, nutritional, dietetic attributes, achieved by standardised processing of industrial technologies, while the more pragmatic way of living could have increased the cost opportunity for food preparations. However, the growth of San Daniele ham demand shows that, despite these changes in life style and convergence toward the international "fast food "stereotypes, the search for quality of typical food is growing and segmented markets are possible when producers are committed to produce quality and better chain organisation can combine the original product quality with processing technologies and market strategies to improve the consumer perception for typical products.

description: As the number of vehicles and devices equipped with GPS technology has grown explosively, an urgent need has arisen for time- and space-efficient data structures to represent their trajectories. The most commonly desired queries are the following: queries about an object’s trajectory, range queries, and nearest neighbor queries. In this paper, we consider that the objects can move freely and we present a new compressed data structure for storing their trajectories, based on a combination of logs and snapshots, with the logs storing sequences of the objects’ relative movements and the snapshots storing their absolute positions sampled at regular time intervals. We call our data structure ContaCT because it provides Constant- time access to Compressed Trajectories. Its logs are based on a compact partial-sums data structure that returns cumulative displacement in constant time, and allows us to compute in constant time any object’s position at any instant, enabling a speedup when processing several other queries. We have compared ContaCT experimentally with another compact data structure for trajectories, called GraCT, and with a classic spatio-temporal index, the MVR-tree. Our results show that ContaCT outperforms the MVR-tree by orders of magnitude in space and also outperforms the compressed representation in time performance.

description: Anaemia is a global health problem, whose development is influenced by several factors. Helicobacter pylori infection is among the factors associated with anaemia. Long term interruption of malaria transmission in the highland area of Kipsamoite led to an increase of haemoglobin levels in some few individuals. However, there are still reported cases of low Hb levels associated with anaemia. In studies that have been done on the role of H. pylori infections on anaemia, researchers hold varied views on whether or not H. pylori infections play a role in iron deficiency anaemia. This study investigated the association between H. pylori infections and anaemia in children aged 5-15 years in Western highland region of Kenya. The study adopted a case-control design and purposive sampling technique was used in selection of subjects. Haemoglobin levels and H. pylori occurrence were measured and entered into Microsoft excel. These data was summarized into descriptive statistics. Chi-square was used in hypotheses testing. A total of 105 participants were enrolled, 35 were cases and 70 were the controls. The mean haemoglobin level was found to be statistically significantly (p<0.00), haemoglobin of cases was lower (11.05 1.726) than that of controls (13.011.897). The proportion of anaemic children among the cases was 77.1% (27) while the non-anaemic were 22.9% (8). The Chi-square showed positive statistical significant difference (p<0.05) between cases and controls. The study concluded that there was a great association between H. pylori infection and occurrence of anaemia in Western region of Kenya.

description: This paper presents a detailed study of the physical properties of seven C IV absorbers identified at z_abs = 0.68-1.28 along the line of sight toward QSO PG 1522+101 (z_QSO = 1.330). The study leverages high-quality QSO spectra from HST COS and STIS, and Keck HIRES to resolve component structures and to constrain the gas density and elemental abundances of individual components. Under the assumption of photoionization equilibrium (PIE), five of the 12 C IV components require a mixture of high- and low-density phases to fully explain the observed relative abundances between low-, intermediate-, and high-ionization species. In addition, galaxy surveys carried out using VLT MUSE and Magellan LDSS3C are utilized to characterize the galaxy environments. The results of this analysis are summarized as follows: (1) no luminous galaxies (> 0.1 L*) are found within 100 kpc in projected distance from the C IV absorbers; (2) the C IV selection preferentially targets high-metallicity (near solar) and chemically-evolved gas (~ solar [C/O] elemental abundances) in galaxy halos; (3) the observed narrow line widths of individual C IV components, places a stringent limit on the gas temperature (< 5e4 K) and supports a photoionization origin; (4) additional local ionizing sources beyond the UV ionizing background may be necessary for at least one absorber based on the observed deficit of He I relative to H I; and (5) a PIE assumption may not apply when the gas metallicity exceeds the solar value and the component line width implies a warmer temperature than expected from PIE models.

description: FT-MIR spectroscopy coupled to chemometrics can be an alternative technique to conventional methods to determine the chemical composition of berries such as strawberry. This study developed chemometric models based on FT-MIR spectroscopy to identify strawberry cultivars at seven stages of ripening and quantify the main attributes involved in sensory quality of strawberry fruits (total soluble solids, total acidity, reducing sugars, pH) and the main bioactive compounds involved in antioxidant capacities (ascorbic acid, phenolics, flavonoids, anthocyanins). PCR, PLS1 and PLS2 algorithms were used to develop the prediction models. PLS1 algorithm developed excellent predictions with Rc2 -greater than 0.90. SIMCA model identified the cultivars with 99% confidence. Unlike conventional methods, FT-MIR allowed us to analyze simultaneously the attributes of quality, bioactive compounds, and antioxidant capacity of strawberries fruits in a fast and reliable way without the use of reagents and/or solvents, which considerably reduces the time and cost of the analyzes.

description: The AdS/CFT correspondence is explored for ``partially massless'' fields in AdS space (which have fewer helicity states than a massive field but more than a conventional massless field). Such fields correspond in the boundary conformal field theory to fields obeying a certain conformally-invariant differential equation that has been described by Eastwood et al. The first descendant of such a field is a conformal field of negative norm. Hence, partially massless fields may make more physical sense in de Sitter as opposed to Anti de Sitter space.

description: We show that strong electron-electron interactions in cavity-coupled quantum materials can enable collectively enhanced light-matter interactions with ultrastrong effective coupling strengths. As a paradigmatic example we consider a Fermi-Hubbard model coupled to a single-mode cavity and find that resonant electron-cavity interactions result in the formation of a quasi-continuum of polariton branches. The vacuum Rabi splitting of the two outermost branches is collectively enhanced and scales with $g_{\text{eff}}\propto\sqrt{2L}$, where $L$ is the number of electronic sites, and the maximal achievable value for $g_{\text{eff}}$ is determined by the volume of the unit cell of the crystal. We find that $g_{\text{eff}}$ for existing quantum materials can by far exceed the width of the first excited Hubbard band. This effect can be experimentally observed via measurements of the optical conductivity and does not require ultra-strong coupling on the single-electron level. Quantum correlations in the electronic ground state as well as the microscopic nature of the light-matter interaction enhance the collective light-matter interaction compared to an ensemble of independent two-level atoms interacting with a cavity mode.

description: The water-energy-food (WEF) nexus is quickly becoming one of the most critical global environmental challenges of the twenty first century. However, WEF systems are inherently complex; they typically are dynamic and span multiple land or agro-ecosystems at a regional or global scale. Addressing this challenge requires a systems approach to optimal and sustainable resource management across multiple dimensions. To that end, using Pajaro Valley (California) as a case study, our research aims to (1) highlight synergies and tradeoffs in food and water production, (2) build a dynamic framework capable of examining intertemporal resource relationships, and (3) detail the steps required to develop incentive-compatible financing of the resulting management plans when benefits are not distributed uniformly across users. Using a stylized model, we find that in the long run, inland growers benefit from the halting of seawater intrusion (SWI) due to overpumping of groundwater. We also calculate that the water provided by the proposed College Lake Multi-Objective Management Program-a plan designed to halt SWI and support sustainable water and agricultural development in the region-will generate net revenue of $40-58 million per year, compared to an annualized cost of less than $3 million. An equal cost-sharing plan would be desirable if the benefit of the project exceeded $1,268 per year for each well owner. Since this may not necessarily be the case for smaller well owners, one possible alternative is to allocate costs in proportion to expected benefits for each user.

 Remarks. Hydroids of Sertularella tenella Alder, 1856 somewhat resemble those of S. rugosa (Linnaeus, 1758) in being relatively small and in having annulated hydrothecae. Cornelius (1995b: 82) listed six characters useful in distinguishing S. tenella from its congener: (1) the aperture is perpendicular to the hydrothecal axis rather than being outward-inclined, (2) hydrothecae are widely separated vertically rather than being bunched together, (3) a notch is absent just below the rim on the abcauline wall of the hydrotheca, (4) hydrothecae are adnate for about ¼ rather than ¼–½ of their length, (5) the number of hydrothecal annulations is 5–6 rather than 3–4, and (6) its typical substrate is usually other hydroids rather than flustrid bryozoans.
 Records indicate that S. tenella is common along the coast of western Sweden from the mid-Kattegat northwards (see Checklist). By contrast, it is reportedly infrequent in Danish waters (Kramp 1935b) and in the Oslofjord (Christiansen 1972).
Records of this typically boreal species from the Caribbean region (e.g., Fraser 1944) are almost certainly erroneous.

description: Over the past five years, significant progress has been made in understanding the magnetism and electronic properties of CaAl$_2$Si$_2$-type Eu$M_2X_2$ ($M$ = Zn, Cd; $X$ = P, As) compounds. Prior theoretical work and experimental studies suggested that EuCd$_2$As$_2$ had the potential to host rich topological phases, particularly an ideal magnetic Weyl semimetal state when the spins are polarized along the c axis. However, this perspective is challenged by recent experiments utilizing samples featuring ultra-low carrier densities, as well as meticulous calculations employing various approaches. Nonetheless, the Eu$M_2X_2$ family still exhibit numerous novel properties that remain to be satisfactorily explained, such as the giant nonlinear anomalous Hall effect and the colossal magnetoresistance effect. Moreover, Eu$M_2X_2$ compounds can be transformed from semiconducting antiferromagnets to metallic ferromagnets by introducing a small number of carriers or applying external pressure, and a further increase in the ferromagnetic transition temperature can be achieved by reducing the unit cell volume. These features make the Eu$M_2X_2$ family a fertile platform for studying the interplay between magnetism and charge transport, and an excellent candidate for applications in spintronics. This paper presents a comprehensive review of the magnetic and transport behaviors of Eu$M_2X_2$ compounds with varying carrier densities, as well as the current insights into these characteristics. An outlook for future research opportunities is also provided.

description: We present a quantum model for the motion of N point particles, implying nonlocal (i.e., superluminal) influences of external fields on the trajectories, that is nonetheless fully relativistic. In contrast to other models that have been proposed, this one involves no additional space-time structure as would be provided by a (possibly dynamical) foliation of space-time. This is achieved through the interplay of opposite microcausal and macrocausal (i.e., thermodynamic) arrows of time.

description: Although the equations of motion for the Neveu-Schwarz (NS) and Ramond (R) sectors of open superstring field theory can be covariantly expressed in terms of one NS and one R string field, picture-changing problems prevent the construction of an action involving these two string fields. However, a consistent action can be constructed by dividing the NS and R states into three string fields which are real, chiral and antichiral. The open superstring field theory action includes a WZW-like term for the real field and holomorphic Chern-Simons-like terms for the chiral and antichiral fields. Different versions of the action can be constructed with either manifest d=8 Lorentz covariance or manifest N=1 d=4 super-Poincaré covariance. The lack of a manifestly d=10 Lorentz covariant action is related to the self-dual five-form in the Type IIB R-R sector.

description: In this study we combine the classical models of the massive and massless spinning particles, derive the current-current interaction Lagrangian of the particles from the gauge transformations of the classical spinors, and discuss radiative processes in electrodynamics by using the solutions of the Dirac equation and the quantum wave equations of the photon. The longitudinal polarized photon states give a new idea about the vacuum concept in electrodynamics.

description: Soybean [Glycine max (L.) Merrill] is known for nitrogen fixation by rhizobia present in the soil with which it establishes an efficient symbiosis. In Zambia, current rhizobial inoculants used in soybeans production are based on non-indigenous strains; this creates a need to isolate local strains that can be used for the development of local inoculants for soybeans in Zambian soils. This paper reports the isolation and characterization of rhizobial isolates from virgin and cultivated soils of the three agro-ecological regions of Zambia. Rhizobia were isolated using the Trap Method and characterized using selected morphological and biochemical markers. A total of 61 isolates were isolated on Yeast Extract Mannitol (YEM) agar medium. Isolates varied in colony form, color, margin and texture. From the 61 isolates from the three regions, 87 % were circular, 8 % irregular and 5 % punctuate in form with 100 % convex elevation. The isolates had 88% entire, 10% undulate and 2 % lobate colony margins with different colors – 56 % cream, 24 % white, 11 % yellow, 5 % transparent and 3 % pink. Transparent colonies were peculiar to Region I and III while pink colonies were peculiar to Region III. All isolates produced mucous, were gram negative and rod shaped, a characteristic of rhizobial cells. None of the isolates could tolerate extremes of pH (4 and 9) in growth medium but grew well at pH 6.8. All isolates utilized glucose as a source of carbon. Based on the Bromothymol Blue (BTB) assay, 59 isolates were fast growing while two isolates from cultivated soils of region II were slow growing. The fast growing 59 isolates showed an acidic reaction changing the medium from green to yellow, while the others showed an alkaline reaction. Based on the results, the 59 fast-growers could be Ensifer fredii or/and Rhizobium tropici rather than Bradyrhizobium. However, further tests to confirm these findings using ketolactose, genetic characterization and inclusion of reference strains, are still needed and are being recommended here.

description: Generating high magnetic fields requires materials with not only high electric conductivity, but also good strength properties in order to withstand the necessarily strong Lorentz forces. A number of bi-metal composites, most notably Cu/Nb, are considered to be good candidates for this purpose. Here, we generalize our previous work on Cu/Nb in order to predict, from theory, the dependence of electric conductivity on the microstructure and volume fraction of the less conductive component for a number of other bi-metal composites. Together with information on strength properties (taken from previous literature), the conductivity information we provide in this work can help to identify new promising candidate materials (such as Cu/Nb, Cu/Ag, Cu/W, ...) for magnet applications with the highest achievable field strengths.

description: The improved cowpea and maize production methods developed in Ghana with the help of farmers are fundamental to increasing cowpea and maize productivity. Improved agronomic practices in cowpea and maize production believed to increase yield are row planting, the use of cover crops and the use of poultry manure. However, the practices are gradually losing their importance in cowpea and maize production. The paper therefore explores the extent to which various factors affect the disadoption of improved agronomic practices and reasons behind disadoption. Multistage sampling techniques were used to select hundred farmers from two cowpea and maize producing areas. Results revealed adoption of cover crops, row planting, poultry manure dropped from 13% to 6%, 99% to 53% and 77% to 10%, respectively. Financial constraint, difficulty in use, time and labour intensity were reasons for disadoption. Empirical results revealed that number of years in education, gender of farm household head, household size, access to extension and hired labour influenced disadoption of improved agronomic practices. Access to production inputs and continuous supply of information are important for farmers’ continuous use of improved agricultural technologies.

 Remarks. The genus Filellum Hincks, 1868 and species assigned to it, including F. serpens (Hassall, 1848), were reviewed and revised by Peña Cantero et al. (1998) and Marques et al. (2011). Threats to nomenclatural stability of both generic and specific names of F. serpens by lesser known senior synonyms were removed under a ruling (Opinion 1485) by the ICZN (1988).
 Ten species were recognized as valid in Filellum worldwide by Marques et al. (2011). Trophosomes in these hydroids are stolonal and simple, comprising sessile and tubular hydrothecae, and identification of species can be difficult or impossible in the absence of gonophores. Gonothecae are aggregated to form a coppinia, the form of which can be diagnostic.
 Filellum serpens, type species of the genus by monotypy, is common in southwestern Scandinavia (Kramp 1935b; Jägerskiöld 1971; Christiansen 1972). It is a boreal, eurybathic species, often found growing on other hydroids and especially on sertulariids (Cornelius 1995a; Peña Cantero et al. 1998; Marques et al. 2011). Christiansen (1972: 297) also observed it on “...algae, stones, shells, dead Lophelia, calcareous polychaete tubes and tests of the foraminifer Rhabdammina.”
 Reported distribution. West coast of Sweden.—From near the border with Norway (Jägerskiöld 1971) to the Öresund (Lönnberg 1898; Kramp 1935b).
 Elsewhere.—North Atlantic from Spitzbergen and northern seas of the Russian Federation (Calder 1970) to the Mediterranean Sea (Peña Cantero et al. 1998) in the east, and from northern Foxe Basin in the Canadian Arctic to Buzzard’s Bay, Massachusetts (Calder 2004) in the west. Although reports suggest that the species is virtually cosmopolitan, many records are suspect in the absence of coppinia (Marques et al. 2011). It is likely restricted largely to boreal regions.

Scalar Multi-Solitons on the Fuzzy Sphere

Year: 2001

description: We study solitons in scalar theories with polynomial interactions on the fuzzy sphere. Such solitons are described by projection operators of rank k, and hence the moduli space for the solitons is the Grassmannian Gr(k,2j+1). The gradient term of the action provides a non-trivial potential on Gr(k,2j+1), thus reducing the moduli space. We construct configurations corresponding to well-separated solitons, and show that although the solitons attract each other, the attraction vanishes in the limit of large j. In this limit, it is argued that the moduli space is CP^k. For the k-soliton bound state, the moduli space is simply CP^1, all other moduli being lifted. We find that the moduli space of multi-solitons is smooth and that there are no singularities as several solitons coalesce. When the fuzzy S^2 is flattened to a noncommutative plane, we find agreement with the known results, modulo some operator-ordering ambiguities. This suggests that the fuzzy sphere is a natural way to regulate the noncommutative plane both in the ultraviolet and infrared.

A dichotomy of sets via typical differentiability

description: We obtain a criterion for an analytic subset of a Euclidean space to contain points of differentiability of a typical Lipschitz function, namely, that it cannot be covered by countably many sets, each of which is closed and purely unrectifiable (has zero length intersection with every $C^1$ curve). Surprisingly, we establish that any set failing this criterion witnesses the opposite extreme of typical behaviour: In any such coverable set a typical Lipschitz function is everywhere severely non-differentiable.

description: Additional File 3: Fig. S2. Experimental workflow of phosphoproteomic analysis of NF-PitNETs. Patients were divided into three groups: non-invasive/non-recurrent (NI/NR), invasive (I), and recurrent (R). For quantification peptides were labelled with tandem mass tags (TMT). Phosphopeptide enrichment was done by titanium dioxide (TiO2) and fractionated by basic reverse phase liquid chromatography (bRPLC) prior to LC–MS/MS analysis on two different mass spectrometrs, Orbitrap Velos and Orbitarp Fusion Tribrid mass spectrometer (ThermoScientific). Peptides identified in triplicates were further used for in-silico functional analysis and validation on large cohort (n = 200) by immunohistochemistry on tissue microarray (TMA).

description: The effect of vacuum annealing thin films of the compensated ferrimagnetic half-metal Mn2RuxGa at temperatures from 250 to 400 degree Celsius is investigated. The 39.3 nm films deposited on (100) MgO substrates exhibit perpendicular magnetic anisotropy due to a small 1% tetragonal elongation induced by substrate strain. The main change on annealing is a modification in the compensation temperature, which first increases from 50 K for the as-deposited film to 185 K after annealing at 250 degree Celsius, and then falls to 140 K after annealing at 400 degree Celsius. There are minor changes in the atomic order, coercivity, resistivity and anomalous Hall effect (AHE), but the net magnetization measured by SQUID magnetometry with the field applied in-plane or perpendicular-to-the-plane changes more significantly. It saturates at 20 to 30 kA/m at room temperature, and a small soft component is seen in the perpendicular SQUID loops which is absent in the square AHE hysteresis loops. This is explained by the half-metallic nature of the compound; the AHE probes only the 4c Mn sublattice that provides the spin-polarized electrons at the Fermi level, whereas the SQUID measures the sum of the oppositely-aligned 4c and 4a sublattice magnetisations.
