The Ultraviolet Extinction in the GALEX Bands

Interstellar extinction in ultraviolet is the most severe in comparison with optical and infrared wavebands and a precise determination plays an important role in correctly recovering the ultraviolet brightness and colors of objects. By finding the observed bluest colors at the given effective temperature and metallicity range of dwarf stars, stellar intrinsic colors, C B , V 0 , C NUV , B 0 , C FUV , B 0 , and C FUV , NUV 0 , are derived according to the stellar parameters from the LAMOST spectroscopic survey and photometric results from the GALEX and APASS surveys. With the derived intrinsic colors, the ultraviolet color excesses are calculated for about 25,000 A- and F-type dwarf stars. Analysis of the color excess ratios yields the extinction law related to the GALEX UV bands: ENUV,B/EB,V = 3.77, EFUV,B/EB,V = 3.39, and EFUV,NUV/EB,V = −0.38. The results agree very well with previous works in the NUV band and in general with the extinction curve derived by Fitzpatrick (1999) for RV = 3.35.
Un groupe hyperbolique est d'etermin'e par son bord

A position-transmitting equipment especially suitable for transmitting steering commands in a small watercraft comprises a transmitter unit in which a cylinder is reciprocable endwise in a housing in accordance with position information to be transmitted. The cylinder is divided internally into two working chambers by a transverse partition. A gland at each end of the cylinder seals about a tubular plunger fixed to the housing so that reciprocation of the cylinder differentially adjusts the working chamber volumes, without risk of jamming and the need for close tolerances. The housing, cylinder and plungers can all be made of plastics material. The plungers provide communication via conduits to a double-acting actuator constituting a receiver unit. The equipment optionally includes a recuperator unit to maintain a selected working fluid pressure in the system.
Investigating The Weekend Anomaly and Its Implications: Evidence From International Financial Markets

Purpose: As contended in prior literature, the weekend anomaly is the tendency for financial markets or security prices to be lower on Mondays than on previous Fridays. The aim of this study was to empirically investigate the weekend anomaly in seven international financial markets namely; NASDAQ Index, CAC 40 Index, DAX Index, JPX-Nikkei Index 400, SSE Index, BIST and JSE Index. Methodology: This study made use of the F- statistics test for the most recent 5 years August 22, 2017 to August 22, 2022. Findings: Contrary to the findings in the literature, there is no evidence to support the weekend anomaly. This was evident in the pvalues for the F-statistics test in all the financial markets under consideration to be statistically insignificant. Originality/Value: Although this concept may have existed, it is no longer applicable hence traders and market participants should avoid regular or pure arbitrage strategy as it may result in significant losses. As per the author’s knowledge, this study is the first to empirically investigate the weekend anomaly in seven international markets using the most recent data.
Structure in additively nonsmoothing sets

Sets with many additive quadruples are guaranteed to have many additive octuples, by H\"{o}lder's inequality. Sets with not many more than this are said to be additively nonsmoothing. We give a new proof of a structural theorem for nonsmoothing sets that originally appeared in work of the authors (\cite{BK}) on the size of cap sets in $F_3 ^N$.
SCUBA-2 follow-up of Herschel-SPIRE observed Planck overdensities

We present SCUBA-2 follow-up of 61 candidate high-redshift Planck sources. Of these, 10 are confirmed strong gravitational lenses and comprise some of the brightest such submm sources on the observed sky, while 51 are candidate proto-cluster fields undergoing massive starburst events. With the accompanying Herschel-Spectral and Photometric Imaging Receiver observations and assuming an empirical dust temperature prior of $$34^{+13}_{-9}$$ K, we provide photometric redshift and far-IR luminosity estimates for 172 SCUBA-2-selected sources within these Planck overdensity fields. The redshift distribution of the sources peak between a redshift of 2 and 4, with one-third of the sources having S_500/S_350 > 1. For the majority of the sources, we find far-IR luminosities of approximately 10^13 L_⊙, corresponding to star formation rates of around 1000 M_⊙ yr^−1. For S_850 > 8 mJy sources, we show that there is up to an order of magnitude increase in star formation rate density and an increase in uncorrected number counts of 6 for S_850 > 8 mJy when compared to typical cosmological survey fields. The sources detected with SCUBA-2 account for only approximately 5 per cent of the Planck flux at 353 GHz, and thus many more fainter sources are expected in these fields.
Half Diallel Analysis and Heat Stress Tolerance Indices for Grain Yield in Bread Wheat

Heterosis and combining ability were determined in bread wheat using 6 x 6 half diallel analysis under normal and late planting dates during seasons 2019/2020 and 2020/2021 at Al-Matana Agricultural Research Station, Agricultural Research Center, Luxor governorate. Mean squares due to genotypes, parents, crosses, general (GCA) and specific combining ability (SCA) were significant or highly significant for the most traits. Days to heading (DH), plant height (PH), spike length (SL) under both dates in addition spikes/plant (NS/P), biological yield/plant (BY/P), harvest index (HI) and 1000 grains weight under normal date and grain yield/plant (GY/P), grains/spike (NG/S) under late date were controlled by additive gene action. The rest traits were controlled by dominance gene action. Under normal date, Sids 14 proved to be a good combiner for NS/P and BY/P. All crosses showed positive highly significant heterobeltiosis for GY/P. The crosses P1XP5 and P3XP4 showed significant or highly significant positive SCA for BY/P, GY/P, number and weight of grains/spike. Under late date, Gemmeiza 11 and Misr 2 proved as good combiner for BY/P, GY/P and NG/S. Significant positive GCA effects found for GY/P of Shandaweel 1. SCA effects were positive significant or highly significant for BY/P and GY/P of the four crosses P1XP3, P1XP5, P2XP6 and P4XP6. The crosses P2XP6, P3XP4, P3XP6 and P4XP6 showed highly significant heterobeltiosis for GY/P. It could be concluded that the two crosses of P1XP5 and P2XP6 were the most heat tolerance with high yield and could be used to obtain segregating populations to apply selection.
Dependencies of GPS Scintillation Indices on the Ionospheric Plasma Drift and Rate of Change of TEC Around the Dawn Sector of the Polar Ionosphere

The dependencies of global positioning system (GPS) scintillation indices on ionospheric plasma flow and the rate of change of total electron content (TEC) around the dawn sector for the first time of the polar ionosphere are investigated. The phase scintillation index (σφ) derived from GPS measurements of the Canadian High Arctic Ionospheric Network (CHAIN) shows linear dependencies on both the plasma drift speed measured by the SuperDARN radar and on the rate of change of TEC estimated from the GPS receivers of CHAIN. However, the amplitude scintillation index (S4) does not show any dependence on the plasma flow or the rate of change of TEC. These results further support Wang et al. (2018), https://doi.org/10.1002/2017JA024805 at the noon sector. The dependence of the phase scintillation index on the plasma flow further evidences that the standard phase scintillation index is dominated by refractive variations due to the use of a fixed cut‐off frequency of 0.1 Hz while detrending the phase observable. The dependence of the phase scintillation index on the rate of change of TEC consolidates the dominance of refractive variations inside.

Role of Anti-C1q Antibodies as Indicator of Renal Activity in Systemic Lupus Erythematosus

Background: Several investigations have found a correlation between serum anti-C1q autoantibodies and peripheral lymphocyte apoptosis among systemic lupus erythematosus (SLE) patients. Objective: It was to assess correlation between anti-C1q, lupus nephritis and other markers of lupus activity. Patients and Methods: This case-control study was conducted in Internal Medicine Department in cooperation with Clinical Pathology Department. This study was performed on 72 cases and were allocated into three equal groups: SLE with nephritis group, SLE without nephritis group, and control group. Measurements of anti-C1q titers were carried out with by (ELISA) kits. Results: Anti-C1q antibody levels varied significantly amongst the groups. Post hoc test showed that there was a statistical significance increase in anti-C1q among SLE with nephritis compared to SLE who don’t have nephritis and control and among SLE without nephritis compared to control. Anti-C1q antibodies validity to diagnose LN among the studied group showed that anti-C1q at cut off >88.058 ng/ml had sensitivity 75%, specificity 75%, accuracy 75%, PPV of 75% and NPV of 75% in diagnosis of LN among cases groups. Conclusion: Anti-Clq autoantibodies, like other standard markers like renal SLEDAI, correlate with renal flare-ups as well as renal disease activity.
The simple complexity of a Riemann surface

\noindent Given a Riemann surface $M$, the \emph{complexity} of a branched cover of $M$ to the Riemann sphere $S^2$, of degree $d$ and with branching set of cardinality $n \geq 3$, is defined as $d$ times the hyperbolic area of the complement of its branching set in $S^2$. A branched cover $p \colon M \to S^2$ of degree $d$ is \emph{simple} if the cardinality of the pre-image $p^{-1}(y)$ is at least $d-1$ for all $y \in S^2$. The \emph{(simple) complexity} of $M$ is defined as the infimum of the complexities of all (simple) branched covers of $M$ to $S^2$. We prove that if $M$ is a closed, connected, orientable Riemann surface of genus $g \geq 1$, then: (1) its simple complexity equals $8\pi g$, and (2) its complexity equals $2\pi(m_{\text{min}}+2g-2)$, where $m_{\text{min}}$ is the minimum total length of a branch datum realizable by a branched cover $p \colon M \to S^2$.

Abdomen width (AW) was measured from the greatest width of the fifth abdominal segment in females, and pleopod length (PL) was measured from the tip to the base in males. All were taken by means of a Vernier Calipers with an accuracy of 0.1 mm.
Delayed Diagnosis of Intestinal Tuberculosis: A Case Report

Abdominal tuberculosis is an uncommon clinical entity, and it can involve the gastrointestinal tract but also the peritoneum, lymph nodes, and solid organs. Its prevalence is higher among individuals from endemic regions for tuberculosis. Epidemiological risk factors associated with typical symptoms and complementary exams should prompt early treatment. We describe the case of a 47-year-old man, originally from India, residing in Portugal for approximately a year. He presented to our emergency department with a three-week-long history of diarrhea, diffuse abdominal pain, more intense on the left quadrants of the abdomen, anorexia, asthenia, and loss of nearly 10% of his body weight. Abdominal and pelvic imaging showed diffuse circumferential thickening of the distal ileum and adjacent mesentery with associated lymphadenopathies. A colonoscopy confirmed the presence of an ulcerated deformative lesion of the cecum with the involvement of the terminal ileum. Initial suspicion of infectious colitis versus inflammatory bowel disease led the team to prescribe antibiotics and corticosteroid therapy, which was associated with bronchoalveolar lavage and sputum samples negative for Mycobacterium tuberculosis, delaying the diagnosis of intestinal tuberculosis. The lack of improvement after weeks of the initial medical therapy, and with histopathological examination of cervical lymphadenopathy showing the presence of granulomatous lymphadenitis with necrosis, led the medical team to start antituberculostatic therapy. The patient showed significant clinical and laboratory improvement, but after two months of adequate treatment a cavitated nodule appeared on the upper lobe of the left lung, and a Mycobacterium tuberculosis complex was identified in the bronchoalveolar lavage. Timely diagnosis and adequate treatment are essential to lower mortality rates of intestinal tuberculosis, and epidemiological risk factors have a great deal of importance on this matter and must always be taken into account.
Strings of ultracold molecules in a synthetic dimension

We consider ultracold polar molecules trapped in a unit-filled one-dimensional chain in real space created with an optical lattice or a tweezer array and illuminated by microwaves that resonantly drive transitions within a chain of rotational states. We describe the system by a two-dimensional lattice model, with the first dimension being a lattice in real space and the second dimension being a lattice in a synthetic direction composed of rotational states. We calculate this system's ground-state phase diagram. We show that as the dipole interaction strength is increased, the molecules undergo a phase transition from a two-dimensional gas to a phase in which the molecules bind together and form a string that resembles a one-dimensional object living in the two-dimensional (i.e, one real and one synthetic dimensional) space. We demonstrate this with two complementary techniques: numerical calculations using matrix product state techniques and an analytic solution in the limit of infinitely strong dipole interaction. Our calculations reveal that the string phase at infinite interaction is effectively described by emergent particles living on the string and that this leads to a rich spectrum with excitations missed in earlier mean-field treatments.
Ladderlike optical conductivity in the spin-fermion model

In the nested limit of the spin-fermion model for the cuprates,one-dimensional physics in the form of half-filled two-leg laddersemerges. We show that the renormalization group flow of thecorresponding ladder is towards the d-Mott phase, a gapped spin-liquidwith short-ranged d-wave pairing correlations, and reveals anintermediate SO(5 ) × SO(3) symmetry. We use the results of therenormalization group in combination with a memory-function approach tocalculate the optical conductivity of the spin-fermion model in thehigh-frequency regime, where processes within the hot spot regiondominate the transport. We argue that umklapp processes play a majorrole. For finite temperatures, we determine the resistivity in thezero-frequency (dc) limit. Our results show an approximate lineartemperature dependence of the resistivity and a conductivity thatfollows a nonuniversal power law. A comparison to experimental datasupports our assumption that the conductivity is dominated by theantinodal contribution above the pseudogap.
Effect of sweet chestnut (Castanea sativa) in streptozotocin induced diabetic rats

Diabetic chronic hyperglycemia is connected with organ deterioration, malfunction, and failure, including the kidneys. The current study explores the positive effects of chestnut ( Castanea sativa ) therapy on oxidative stress and renal function in streptozotocin "STZ" induced diabetic rats, as well as assesses the sensory properties of baked cookies containing varying doses of chestnuts. Thirty-five rats were used in this study and were divided into the following 5; group (1) or (-ve control) provided a baseline diet, and the remaining were injected with streptozotocin "STZ" and fed experimental diets for four weeks after the diabetes mellitus "DM" was confirmed. Group (2) or (+ve control) includes DM-rats without treatment; groups (3,4 & 5) DM-rats treated with 5, 10 and 15% CS, respectively. At the ending period, samples of blood were collected for measuring levels of blood glucose, serum HB1C, uric acid, creatinine and urea levels, malondialdehyde, superoxide dismutase "SOD", and glutathione levels "GSH", Results indicated that STZ induced diabetic rats (DM-positive) showed highly significant (P< 0.01) increase in their blood glucose, MDA, serum urea, serum creatinine, and serum uric acid and a highly significant decrease (P< 0.01) in GSH and SOD levels. DM rats fed CS had a significant decrease in their serum blood glucose, MDA, creatinine, and uric acid and an increase in GSH and SOD levels. Therefore, CS can be used in controlling diabetes and its harmful consequences and to enhance the antioxidant status and renal protective effects in diabetic rats. Also, Sensory evaluation results revealed that cookies prepared with CS at 5%, 10%, and 15 % were accepted by panellists with different ratings.
Mechanistic role of epigallocatechin-3-gallate in regulation of the antioxidant markers in ethanol induced liver damage in mice

ABSTRACT Background: Failure of endogenous antioxidant system to eliminate high levels of ROS results to oxidative stress, consequently leading to liver damage. Excessive alcohol consumption leads to liver damage due to ROS generation, thus regarded as the leading causes of death worldwide, suggesting great need for use of exogenous antioxidants like epigallocatechin-3-gallate (EGCG), to avert liver damage. However, underlying EGCG mechanisms remains elusive.Aim of the work: This study focused on mechanistic role of EGCG in regulation of antioxidant marker activities during ethanol induced liver damage.Materials and Methods: 20 male Swiss Albino mice were divided into four groups and treated with different dosage. ALT, AST and total proteins were determined as indicators of liver damage. MDA and protein carbonyls were measured as oxidative stress markers. Activities of SOD and CAT were determined. SOD-2 and CAT differential gene expression were also determined. Liver histology analysis by H&E staining. All the experiments were run in duplicates. ANOVA was used to analyzes data using Tukey’s multiple comparison tests and results considered statistically significant if p ≤ 0.05 at 95% confidence level. Results: Findings revealed that chronic consumption of ethanol leads to liver damage through increased levels of serum ALT and AST, MDA, protein carbonyls and remarkable diffuse lipid droplets and decreased enzyme activity of SOD and CAT. EGCG increased activity of SOD and CAT and SOD-2 expression and did not affect CAT expression. Conclusion: In summary, ethanol induces liver damage, and administration of EGCG increases antioxidant system expression, suggesting its role in regulating their activities, defensive of oxidative stress through various pathways.
