description: We report the synthesis, structure and nonlinear optical properties of cadmium sulphide (CdS) nanocrystallines (NCs) synthesized electrochemically both with and without detergent ATLAS G3300. Relevant structural and morphological features are explored by X-ray diffraction and scanning electron microscopy (SEM) techniques. The efficiency of the second harmonic generation (SHG) appears to be strongly dependent on the energy density of the incident fundamental laser radiation and NC sizes.

description: The present meta-analysis of propensity score-matching studies aimed to compare the long-term survival outcomes and adverse events associated with coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) in patients with chronic kidney disease (CKD). Electronic databases were searched for studies comparing CABG and PCI in patients with CKD. The search period extended to 13 February 2021. The primary outcome was all-cause mortality, and the secondary endpoints included myocardial infarction, revascularization, and stroke. Odds ratios (ORs) and hazard ratios (HRs) with 95% confidence intervals (CIs) were used to express the pooled effect. Study quality was assessed using the Newcastle–Ottawa scale. The analyses were performed using RevMan 5.3. Thirteen studies involving 18,005 patients were included in the meta-analysis. Long-term mortality risk was significantly lower in the CABG group than in the PCI group (HR: 0.76, 95% CI: 0.70–0.83, p < .001), and similar results were observed in the subgroup analysis of patients undergoing dialysis and for different estimated glomerular filtration rate ranges. The incidence rates of myocardial infarction (OR: 0.25, 95% CI: 0.12–0.54, p < .001) and revascularization (OR: 0.17, 95% CI: 0.08–0.35, p < .001) were lower in the CABG group than in the PCI group, although there were no significant differences in the incidence of stroke between the two groups (OR: 1.24; 95% CI: 0.89–1.73, p > .05). Subgroup analysis among patients on dialysis yielded similar results. Our propensity score matching analysis revealed that, based on long-term follow-up outcomes, CABG remains superior to PCI in patients with CKD.

description: Petroleum-derived materials are used in various industries due to their flexibility, durability, toughness and high mechanical tensile strength. However, their lack of biodegradability creates a major environmental disposal problem. The growing interest in investigating sustainable alternatives, such as biopolymers, which have proven to be a viable substitute for petroleum-based materials. These are attractive because of their biodegradability, versatility and compatibility with other materials. Starch-based biopolymers are composed of two polymers: amylose and amylopectin. We propose to investigate mechanical properties such as Young's modulus, tensile strength and flexibility. Using Quantum Mechanics (QM) and Molecular Dynamics (MD). MC calculations were performed on the monomer (glucose) using Density Functional Theory (DFT) with ORCA software, with the B3LYP/M06-2X functional up to the cc_PVDZ basis set. Calculations are being performed for geometrical optimization and vibrational frequency, comparing with force function parameters in generic fields. Molecular Dynamics is performed with free software and trajectories are analyzed to predict mechanical properties.

description: In the dynamic landscape of Nigerian politics, public perception plays a pivotal role in shaping the discourse surrounding key political figures. Press conferences are an avenue of addressing salient issues bothering the economy, social welfare, and political dimension of society. Peter Obi, the presidential candidate for the Labour Party in the 2023 presidential election in Nigeria, responded to comments and gave a speech at the world press conference held at Abuja after the ruling of the Apex court that declared the All-Progressives Congress (APC) victorious in that election. The LP’s Mr. Peter Obi was heard saying, “We in the Labour Party, and the ‘Obidient’ Movements will remain in the opposition”. The study therefore aimed to investigate the interpretations of Mr. Peter Obi’s world press conference ‘Opposition comments’ by Chukwuemeka Odumegwu Ojukwu University (COOU) Postgraduate students, examine their perception and attitude regarding the comments, and determine the implications of the comments on Nigerian democracy. Anchored on uses and gratifications as well as perception theories, the study employed the focus group discussion method, with the purposive sampling technique to select 72 discussants from six groups from the population of the Postgraduate students of COOU in Igbariam campus. It was found that a greater majority of the discussants interpreted the comments in a reflective and positive light; and that the attitude of the discussants was steadfast in their struggle for the democratic progress and growth of the country. The study recommends that the media should avoid misrepresenting facts about individuals because the frames attached to people’s comments influence audience understanding of the issue. Again, politicians of high value and acute reputation should like Mr. Peter Obi, speak up in times of political turbulence anywhere in the world
Protoplanetary disk masses from CO isotopologues line emission

description: One of the methods for deriving disk masses relies on direct observations of the gas, whose bulk mass is in the outer cold ($T\lesssim30$K) regions. This zone can be well traced by rotational lines of less abundant CO isotopologues, that probe the gas down to the midplane. The total CO gas mass is then obtained with the isotopologue ratios taken to be constant at the elemental isotope values found in the local ISM. This approach is however imprecise, because isotope selective processes are ignored. The aim of this work is an isotopologue selective treatment of CO isotopologues, in order to obtain a more accurate determination of disk masses. The isotope-selective photodissociation, the main process controlling the abundances of CO isotopologues in the CO-emissive layer, is properly treated for the first time in a full disk model (DALI, Bruderer et al. 2012; Bruderer 2013). The chemistry, thermal balance, line and continuum radiative transfer are all considered together with a chemical network that treats $^{13}$CO, C$^{18}$O, C$^{17}$O, isotopes of all included atoms, and molecules, as independent species. Isotope selective processes lead to regions in the disk where the isotopologues abundance ratios are considerably different from the elemental ratio. The results of this work show that considering CO isotopologue ratios as constants can lead to an underestimate of disk masses by up to almost two orders of magnitude if grains have grown to larger sizes. This may explain observed discrepancies in mass determinations from different tracers. The dependence of the various isotopologues emission on stellar and disk parameters is investigated. Including CO isotope selective processes is crucial to determine the gas mass of the disk accurately (through ALMA observations) and thus to provide the amount of gas which may eventually form planets or change the dynamics of forming planetary systems.

description: In this paper, we use a matrix adaptive filter as the synthesis stage of a Uniform Filter Bank (UFB) to reconstruct the input signal. We first develop the mathematical theory behind it by applying the model of optimal filtering at the synthesis stage of the UFB and obtaining an expression for the matrix Wiener filter. We have developed a theorem which we use to simplify the expression further. In the absence of required information about the analysis stage, we use adaptive filtering to arrive at the Wiener solution. We use the Least Mean Square (LMS) algorithm to update the filter coefficients. Through experimental results, we find that the adaptive filter is convergent for a stable Wiener filter.

description: It has been demonstrated that urinary neutrophil gelatinase-associated lipocalin (NGAL) and calprotectin are helpful biomarkers in the differentiation of intrinsic and prerenal acute kidney injury. The present cross-sectional study investigates, whether urinary biomarkers are able to differentiate primarily inflammatory from non-inflammatory entities in chronic kidney disease (CKD). Urinary calprotectin, NGAL, and kidney injury molecule-1 (KIM-1) concentrations were assessed in a study population of 143 patients with stable CKD and 29 healthy controls. Stable renal function was defined as an eGFR fluctuation ≤5 ml/min/1.73 m2 in the past 12 months. Pyuria, metastatic carcinoma, and renal transplantation were regarded as exclusion criteria. Diabetic nephropathy, hypertensive nephropathy, and polycystic kidney disease were categorized as ‘primarily non-inflammatory renal diseases’ (NIRD), whereas glomerulonephritis and vasculitis were regarded as ‘primarily inflammatory renal diseases’ (IRD). Urinary calprotectin and NGAL concentrations significantly differed between CKD and healthy controls (p < 0.05 each), whereas KIM-1 concentrations did not (p = 0.84). The three biomarkers did neither show significant differences in-between the individual entities, nor the two categories of IRD vs. NIRD (calprotectin 155.7 vs. 96.99 ng/ml; NGAL 14 896 vs. 11 977 pg/ml; KIM-1 1388 vs. 1009 pg/ml; p > 0.05 each). Albumin exceeds the diagnostic power of the investigated biomarkers by far. The urinary biomarkers calprotectin, NGAL, and KIM-1 have no diagnostic value in the differentiation of primarily inflammatory vs. non-inflammatory etiologies of CKD.

description: Clinical diagnosis of the eye is performed over multifarious data modalities including scalar clinical labels, vectorized biomarkers, two-dimensional fundus images, and three-dimensional Optical Coherence Tomography (OCT) scans. Clinical practitioners use all available data modalities for diagnosing and treating eye diseases like Diabetic Retinopathy (DR) or Diabetic Macular Edema (DME). Enabling usage of machine learning algorithms within the ophthalmic medical domain requires research into the relationships and interactions between all relevant data over a treatment period. Existing datasets are limited in that they neither provide data nor consider the explicit relationship modeling between the data modalities. In this paper, we introduce the Ophthalmic Labels for Investigating Visual Eye Semantics (OLIVES) dataset that addresses the above limitation. This is the first OCT and near-IR fundus dataset that includes clinical labels, biomarker labels, disease labels, and time-series patient treatment information from associated clinical trials. The dataset consists of 1268 near-IR fundus images each with at least 49 OCT scans, and 16 biomarkers, along with 4 clinical labels and a disease diagnosis of DR or DME. In total, there are 96 eyes' data averaged over a period of at least two years with each eye treated for an average of 66 weeks and 7 injections. We benchmark the utility of OLIVES dataset for ophthalmic data as well as provide benchmarks and concrete research directions for core and emerging machine learning paradigms within medical image analysis.

description: We propose a quantitative method to classify cities according to their street pattern. We use the conditional probability distribution of shape factor of blocks with a given area, and define what could constitute the `fingerprint' of a city. Using a simple hierarchical clustering method, these fingerprints can then serve as a basis for a typology of cities. We apply this method to a set of 131 cities in the world, and at an intermediate level of the dendrogram, we observe 4 large families of cities characterized by different abundances of blocks of a certain area and shape. At a lower level of the classification, we find that most European cities and American cities in our sample fall in their own sub-category, highlighting quantitatively the differences between the typical layouts of cities in both regions. We also show with the example of New York and its different Boroughs, that the fingerprint of a city can be seen as the sum of the ones characterising the different neighbourhoods inside a city. This method provides a quantitative comparison of urban street patterns, which could be helpful for a better understanding of the causes and mechanisms behind their distinct shapes.

description: The dipping low-mass X-ray binary 4U 1915-05 was observed by Suzaku on 2007 November 8 for a net exposure of 39 ksec. It was detected by the XIS with a 0.8-10 keV signal rate of 9.84+\-0.01 cts/s per camera, and HXD-PIN with a 12-45 keV signal rate of 0.29+/-0.01 cts/s. After removing the periodic dips and an X-ray burst, the 0.8 - 45 keV continuum was successfully described by an optically thick disk emission with an inner-disk temperature ~ 0.7 keV and a neutron-star blackbody emission with a temperature ~ 1.3 keV, on condition that the blackbody component, or possibly the disk emission too, is significantly Comptonized. This successful modeling is consistent with 4U 1915-05 being in a high-soft state in this observation, and implies that its broadband spectrum can be interpreted in the same scheme as for many non-dipping Low-mass X-ray binaries in the soft state. Its bolometric luminosity (~ 0.02 times the Eddington limit) is relatively low for the soft state, but within a tolerance, if considering the distance and inclination uncertainties. As a high-inclination binary, this source exhibited stronger Comptonization effect, with a larger Comptonizing y-parameter, compared to low and medium inclination binaries. This suggests that the Comptonizing coronae of these objects in the soft state is in an oblate (rather than spherical) shape, extending along the accretion disk plane, because the y-parameter would not depend on the inclination if the corona were spherical.

description: Phishing is a form of cybercrime and a threat that allows criminals, phishers, to deceive end users in order to steal their confidential and sensitive information. Attackers usually attempt to manipulate the psychology and emotions of victims. The increasing threat of phishing has made its study worthwhile and much research has been conducted into the issue. This paper explores the emotional factors that have been reported in previous studies to be significant in phishing victimization. In addition, we compare what security organizations and researchers have highlighted in terms of phishing types and categories as well as training in tackling the problem, in a literature review which takes into account all major credible and published sources.

description: AbstractCatholic Flexi schools are an alternative type of school that operate within the Australian schooling system. The paper focuses on Flexis operated by Edmund Rice Education Australia (EREA), the largest provider of flexible education across all education sectors in Australia. They serve young people who have been disenfranchised from mainstream schooling. By their nature, Flexi schools are different in character to mainstream Catholic schools in Australia. Both the young people and the staff of Flexis do not contain the critical mass of Catholics that continue to be evident in other Catholic schools in Australia in spite of changing demographics. This presents a challenge for Flexi schools’ identity leaders, their principals, whose Catholicity is a factor in their recruitment and for whom identity leadership is an expectation of their role. The makeup of Flexis in terms of their young people, their staff, and their principals is then considered. Thereafter and with particular reference to The Identity of the Catholic School for a Culture of Dialogue (CCE, 2022), the Catholic identity of Flexis compared to mainstream Catholic schools in Australia is investigated. Traditional Catholic schools express their Catholic identity through an explicit religious education curriculum, overt religious symbols and iconography, Catholic rituals, and a liturgical and prayer life. The elements of Flexi Catholic identity are a humanising education; inclusivity; a positive anthropology of the human person that is hope-filled and non-judgmental; dialogue; and a practical encounter with the poor and the marginalised which has a “fragrance of the Gospel” because its practitioners “take on the ‘smell of the sheep’” (Francis, 2013, §39; 24). It is suggested that Flexi principals are crucially important and well placed to animate the Catholic identity of their schools through staff formation that honours receptive ecumenism and welcomes interfaith dialogue.

description: La ricerca da me impiantata si fonda sui principi caratterizzanti la Teoria del Connettivismo. In primo luogo, secondo tale teorizzazione, risulta indiscutibile il fatto che lo sviluppo tecnologico e la sua prepotente diffusione nella società e nel processo di insegnamento-apprendimento implichino una trasformazione del paradigma educativo incentrato ormai sulla significatività di determinate connessioni in grado di creare e progettare attività di apprendimento fondate sulla compartecipazione in comunità virtuali diversificate. Riprendendo una citazione di Turkle, asserzione pronunciata nel 1995, le nostre vite sullo schermo condizionano sempre di più il nostro modo di vivere le relazioni affettive e personali. I cambiamenti rilevanti che ne conseguono riguardano tanto i percorsi di apprendimento che l’evoluzione del sé, visto che non sono più fondati esclusivamente sull’educazione ricevuta in ambito familiare o prettamente scolastico o mediante le attività parascolastiche, siano esse sportive, di recupero o ricreative. Di conseguenza identificare le strategie, le attività, i percorsi didattici, gli strumenti e gli ambienti non può prescindere dalle tecnologie diventate sempre più predominanti nella nostra vita, facilitando l’acquisizione di una certa consapevolezza riguardo all’importanza di un approccio più critico, e creativo nell’utilizzo delle risorse di rete e nei processi legati alla gestione delle nostre conoscenze. ..

description: We present a total of ~ 45 ksec (3$\times$15 ksec) of SWIFT XRT observations for three non-magnetic nova-like (NL) Cataclysmic Variables (CVs) (MV Lyr, BZ Cam, V592 Cas) in order to study characteristics of Boundary Layers (BL) in CVs. The nonmagnetic NLs are found mostly in a state of high mass accretion rate ($\ge$1$\times$10$^{-9}$ Msun yr$^{-1}$) and some show occasional low states. Using the XRT data, we find optically thin multiple-temperature cooling flow type emission spectra with X-ray temperatures (kT$_{max}$) of 21-50 keV. These hard X-ray emitting boundary layers diverge from simple isobaric cooling flows indicating X-ray temperatures that are of virial values in the disk. In addition, we detect power law emission components from MV Lyr and BZ Cam and plausibly from V592 Cas which may be a result of the Compton scattering of the optically thin emission from the fast wind outflows in these systems and/or Compton up-scattering of the soft disk photons. The X-ray luminosities of the (multi-temperature) thermal plasma emission in the 0.1-50.0 keV range are (0.9-5.0)$\times$10$^{32}$ erg/sec. The ratio of the X-ray and disk luminosities (calculated from the UV-optical wavelengths) yield an efficiency (L$_{x}$/L$_{disk}$) ~ 0.01-0.001. Given this non-radiative ratio for the X-ray emitting boundary layers with no significant optically thick blackbody emission in the soft X-rays (consistent with ROSAT observations) together with the high/virial X-ray temperatures, we suggest that high state NL systems may have optically thin BLs merged with ADAF-like flows and/or X-ray coronae. In addition, we note that the axisymmetric bipolar and/or rotation dominated fast wind outflows detected in these three NLs (particularly BZ Cam and V592 Cas) or some other NL may also be explained in the context of ADAF-like BL regions.

description: The Mediterranean diet (MD) has been pointed out as a nutritional approach to prevent metabolic disturbances leading to obesity, diabetes and liver steatosis. These properties have been largely attributed to oleic acid and polyphenol compounds present in olive oil (OO), the main fat source of MD. However, there are controversies regarding the consequences of excessive extra virgin olive oil (EVOO) intake. Prolonged high-fat feeding may induce obesity, insulin resistance, and non-alcoholic fatty liver disease. Dysfunction of mitochondrial dynamics along with endoplasmic reticulum (ER) stress, have been suggested to play a role in the establishment of these disturbances. The mechanism seems to involve a prevalence of the fission process over the fusion process, and endoplasmic reticulum stress, with activation of the unfolded protein response (UPR) and consequent stimulation of inflammatory pathways. The dietary fats differ in their lipotocixity degree, with saturated fatty acids being considered more harmful, while the monounsaturated oleic acid has been suggested to protect against lipotoxicity. However, data on the mechanisms involved as well as on the existence of a dose-dependency are not conclusive. Given that the liver is a key organ for the maintenance of the metabolic homeostasis and is highly susceptible to dietary manipulations, focusing on the consequences of high-fat feeding on this tissue is of relevance. With the aim of evaluating these aspects, we used both in vivo and in vitro approaches. The animal study examined body, serum, and hepatic parameters after the prolonged intake of diets containing either normolipidic or hyperlipidic amounts of EVOO. To perform a broad analysis of liver metabolism, a proteomic approach was used. Two months-old swiss mice were fed for 12 weeks with either normolipidic diets (9.5% energy from fat) containing soy oil (control diet, C) or EVOO (NO diet) or a high fat EVOO diet (HO, 39% energy from fat). Body weight and food intake were measured weekly and serum parameters were analyzed by enzymatic methods.

description: Εκτίμηση της διαγνωστικής ακρίβειας της έγχρωμης doppler υπερηχοτομογραφίας, της αξονική αγγειογραφίας (CTA), της μαγνητικής αγγειογραφίας μετά την ενδοφλέβια χορήγηση γαδολινίου (MRA), συγκριτικά με την ψηφιακή αγγειογραφία (DSA), σε ασθενείς με κλινική υποψία νεφραγγειακής υπέρτασης. Συνολικά 58 ασθενείς με υποψία νεφραγγειακής υπέρτασης συμπεριλήφθησαν στην μελέτη. Οι ασθενείς εξετάστηκαν με έγχρωμη υπερηχοτομογραφία, CTA και MRA, μετά την ενδοφλέβια χορήγηση γαδολινίου. Η DSA ήταν η εξέταση αναφοράς, όσον αφορά τον αριθμό των νεφρικών αρτηριών, την ύπαρξη και του βαθμού στένωσης, καθώς και την παρουσία ινομυωματώδους δυσπλασίας. Η DSA ανέδειξε 132 αρτηρίες, 16 στενώσεις και 4 αρτηρίες με ινομυωματώδη δυσπλασία. Το έγχρωμο υπερηχοτομογράφημα δεν ανέδειξε 1 κύρια και 14 πολικές αρτηρίες. Η CTA ανέδειξε όλες τις κύριες αρτηρίες και 7/16 πολικές αρτηρίες, αλλά απέτυχε στην ανάδειξη της στένωσης σε 2 πολικές αρτηρίες. Παρομοίως η MRA δεν ανέδειξε την στένωση σε 2 πολικές αρτηρίες, ανέδειξε 9/16 πολικές αρτηρίες, αλλά απέτυχε στην ανάδειξη 2 κύριων νεφρικών αρτηριών. Όλες οι μέθοδοι ανέδειξαν τις αρτηρίες με ινομυωματώδη δυσπλασία. Η ευαισθησία, η ειδικότητα, η θετική και αρνητική προγνωστική αξία ήταν 75%, 89.6%, 60% και 94.6% αντίστοιχα για το έγχρωμο Doppler US, 94%, 93%, 71% και 99% αντίστοιχα για την CTA και 90%, 94.1%, 75% και 98% αντίστοιχα για την MRA. Η CTA και MRA έχουν συγκρίσιμα και ικανοποιητικά αποτελέσματα, με ιδιαίτερη σημασία στην αρνητική προγνωστική τους αξία, όσον αφορά στην υπόνοια στένωσης της νεφρικής αρτηρίας. Η βασική ιδέα ενός απεικονιστικού αλγορίθμου, συμπεριλαμβάνει το έγχρωμο υπερηχοτομογράφημα, αν είναι διαθέσιμο, και σαν δεύτερο βήμα προτείνεται η CTA και MRA. Η DSA πρέπει να γίνεται, όταν οι δύο προηγούμενες μέθοδοι δεν είναι διαγνωστικές και σε διαδερμικές θεραπευτικές παρεμβάσεις.

Finite temperature Casimir interaction between spheres in $(D+1)$-dimensional spacetime: Exact computations and asymptotic expansions

description: We consider the finite temperature Casimir interaction between two Dirichlet spheres in $(D+1)$-dimensional Minkowski spacetime. The Casimir interaction free energy is derived from the zero temperature Casimir interaction energy via the Matsubara formalism. In the high temperature region, the Casimir interaction is dominated by the term with zero Matsubara frequency, and it is known as the classical term since this term is independent of the Planck constant $\hbar$. Explicit expression of the classical term is derived and it is computed exactly using appropriate similarity transforms of matrices. We then compute the small separation asymptotic expansion of this classical term up to the next-to-leading order term. For the remaining part of the finite temperature Casimir interaction with nonzero Matsubara frequencies, we obtain its small separation asymptotic behavior by applying certain prescriptions to the corresponding asymptotic expansion at zero temperature. This gives us a leading term that is shown to agree precisely with the proximity force approximation at any temperature. The next-to-leading order term at any temperature is also derived and it is expressed as an infinite sum over integrals. To obtain the asymptotic expansion at the low and medium temperature regions, we apply the inverse Mellin transform techniques. In the low temperature region, we obtain results that agree with our previous work on the zero temperature Casimir interaction.

description: We give an introduction into quantum cosmology with emphasis on its conceptual parts. After a general motivation we review the formalism of canonical quantum gravity on which discussions of quantum cosmology are usually based. We then present the minisuperspace Wheeler--DeWitt equation and elaborate on the problem of time, the imposition of boundary conditions, the semiclassical approximation, the origin of irreversibility, and singularity avoidance. Restriction is made to the framework of quantum geometrodynamics.

An exploration of how communities in Lesotho can benefit through Katse, Mohale and Muela dams in economic transformation

description: The government of Lesotho, in partnership with the Republic of South Africa, invested in the construction of Katse, Mohale and Muela dams in the 1980s but since then there is no evidence of these two bodies of water contributing towards agricultural production in Lesotho. The primary business for the construction of these two dams is to supply South Africa with water but Lesotho can maximize on this venture and cost effectively utilize the water for agricultural purposes especially through drip irrigation. The water resource can also boost tourism ventures and the conservation of the environment around the reservoirs. All these ventures, if fully and meaningfully explored, can create much needed employment for local communities. This study therefore seeks to explore the potential presented by the existence of the two dams in Lesotho, especially for boosting agricultural production and establish Lesotho as an independent producer of its own food to feed the nation and boost industry at the same time. Using qualitative methods of data gathering, presentation and analysis, this study sought to establish the efforts by the responsible authorities in Lesotho to boost agriculture production in order to establish a solid agricultural base through irrigation schemes from the dams.

Dust correction factors over $0 < z < 3$ in massive star-forming galaxies from stacking in \emph{Herschel}
Creators: name: Oteo, I.
Publisher: name: arXiv
Year: 2014
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: In this work we use stacking analysis in \emph{Herschel} PACS to study the accuracy of several dust-correction factors typically employed to estimate total star-formation rate (SFR) of high-redshift star-forming (SF) galaxies. We also analyze what stacking suggests about the relation between SFR and stellar mass and the redshift evolution of the specific SFR (${\rm sSFR} = {\rm SFR} / {\rm M_*}$). We find that the dust properties of massive SF galaxies evolve with redshift, being galaxies at $z \sim 2-3$ more attenuated than at $z \sim 1$ for a given UV continuum slope and stellar mass. As a consequence, a single IRX-$β$ relation can not be used to recover the total SFR of massive SF galaxies at $0 \lesssim z \lesssim 3$. This might have implications for higher redshift studies, where a single IRX-$β$ relation derived for local starburst is usually assumed to be valid. However, we find that the local relation between dust attenuation and stellar mass is valid at least up to $z \sim 1$, although deviations are found for higher redshift galaxies where only $\log{\left( M_* / M_\odot \right)} > 10.25-10.50$ galaxies are detected through stacking. This, therefore, does not rule out the possibility that the local dust-mass relation can be valid for less massive SF galaxies at $z \sim 2-3$. The SED fitting procedure with stellar population templates gives over-estimated values (about 0.3--0.5 dex in $\log{\rm SFR}$) of the dust-corrected SFR at all redshifts studied here. We find that the slope of the main-sequence of star formation is less steep than previously found in massive galaxies with $\log{\left( M_* / M_\odot \right)} \geq 10$, and the redshift evolution of the sSFR reported in previous works in massive is well recovered.
