Clinical, Laboratory, Molecular, and Reproductive Aspects of Combined Deficiency of Factors V and VIII
Authors: Yakovleva Elena , Zhang Bin 
Published: August 2024

AbstractCongenital combined deficiency of factor V (FV) and factor VIII (FVIII; F5F8D, OMIM 227300) is a rare hereditary coagulopathy and accounts for approximately 3% of cases of rare coagulation disorders. The prevalence of this disease in the general population is estimated to be 1:1,000,000 and is significantly higher in regions where consanguineous marriages are permitted, such as the Mideast and South Asia. The disease has an autosomal recessive mode of inheritance and therefore occurs with an equal incidence among males and females. Heterozygous mutation carriers usually do not have clinical manifestations. The molecular basis of this disease differs from that of stand-alone congenital deficiencies of FVIII and FV. F5F8D is caused by mutations in either LMAN1 or MCFD2, which encode components of a cargo receptor complex for endoplasmic reticulum to Golgi transport of FV and FVIII, leading to defects in an intracellular transport pathway shared by these two coagulation factors. Congenital combined deficiency of FV and FVIII is characterized by decreased activities of both FV and FVIII in plasma, usually to 5 to 30% of normal. Clinical manifestations in most cases are represented by mild or moderate hemorrhagic syndrome. The simultaneous decreases of two coagulation factors present complications in the diagnosis and management of the disease. In female patients, the disease requires a special approach for family planning, pregnancy management, and parturition. This review summarizes recent progress in clinical, laboratory, and molecular understanding of this disorder.
Congenital Umbilical Cord Hernia: Prenatal and Postnatal Management
Authors: Rodriguez Stephanie , Marty Daisy , Folga Barbara , Alrahmani Layan 
Published: August 2024

AbstractCongenital umbilical cord hernia is often misdiagnosed and easily confused with a small omphalocele. It is different from postnatally diagnosed umbilical hernias and is believed to arise from persistent physiological mid-gut herniation. Its incidence is estimated to be 1 in 5,000, although some articles reported the incidence rate of approximately 0.2%. It is very important to clearly diagnose these cases in the antenatal period so that the patients receive appropriate management postnatally and to decrease the stress in the parents as well. Umbilical cord hernias have not been associated with other chromosomal anomalies.In this article, we describe a case of a patient who was diagnosed with an umbilical cord mass for which the course prenatally and postnatally was uncomplicated. It is very important to avoid misdiagnosing these cases, so that patients are appropriately treated in the postnatal course and to prevent complications such as bowel injury during cord clamping.
Towards an ecological transition from below: insights from a workers' mobilization in the automotive sector
Authors: Andretta Massimiliano , Imperatore Paola 
Published: August 2024

AbstractThis article aims to shed light on the processes and conditions that enable workers to maintain employment stability and wage security while reorganizing production to effectively address the ongoing climate crisis. By thoroughly analysing a case of workers' mobilization within the automotive sector at the GKN plant in Campi Bisenzio (Florence—Italy), we underline the conditions under which workers may support a transformative ecological transition. Their campaign has rapidly become emblematic of a national movement that integrates social and environmental concerns. Through qualitative analysis of social media content, self-produced documents, and in-depth interviews, we illustrate how these workers, by stepping into a gap left by both the state and the market, have advocated for a credible and radical bottom-up transition plan. This plan challenges the power imbalances within the production system and positions workers and the local community as key stakeholders in plant management, as well as guardians of the local territory and its environment. Their organizational model and identity, strategic alliances, and the specific territorial context in which they operate are conducive to this endeavour.

Waspaloy, a nickel-based super alloy, has much potential in gas turbine component production. Machining this type of material using the traditional manufacturing method is very hard. Hence, electrical discharge machining (EDM) was selected for the investigation of the machining characteristics of Waspaloy by choosing the control parameters, namely, current, voltage, pulse on time, pulse off time, and spark gap. Gray relational analysis is carried out using 18 experiments according to an orthogonal array (L18) to determine the gray relation grade for this machining process with multiple machining characteristics such as material removal rate (MR), tool wear rate (TW), and surface roughness (SR). The significant objective of the multi objective optimization to attain high MR, low TW, and low SR is found out. From gray relation optimization, the optimum machining conditions for EDM, namely, current: 26 A, voltage: 200 V, pulse on time: 120 μs, pulse on time: 10 μs, and spark gap: 0.15 m, have been identified. The foremost parameter affecting the responses was found to be peak current.

Published: August 2024

Abstract
A theory of size quantization has been developed for both one-dimensional and zero-dimensional nanostructures, grown from monolayers of transition metal dichalcogenides. Expressions for the energy spectra of charge carriers have been obtained for both even and odd (relative to coordinate inversion) states in the quantum-confined line and point of monolayers of transition metal dichalcogenides, depending on their geometric dimensions. A numerical analysis of the quantum-confined energy states of electrons in nanostructures of monolayers of transition metal dichalcogenides has been conducted.
Chirality transfer torque and transverse Chirality current in the Dirac/magnetic Weyl semimetal junction
Authors: Salehi Morteza 
Published: August 2024

Abstract
We theoretically show that an interface formed by a three-dimensional Dirac/magnetic Weyl semimetal deflects the propagation direction of hitting Weyl fermions according to their Chirality in opposite directions. This effect leads to a Chirality current that flows parallel to the interface. There is an imbalance between the Chirality of Weyl fermions in this current whereas it does not carry any charge. Also, this phenomenon creates an indirect gap in the charge conductance that pass through the circuit. Unlike real spin, Chirality remains a good quantum number in systems characterized by very strong spin-momentum coupling. We derive a continuity equation for the Chirality density wave to elucidate how magnetization alters its dynamics and relates to the transverse Chirality current. Furthermore, we demonstrate a torque, that we called it Chirality transfer torque, imposes on the junction that its value relates to the transverse Chirality current.
Nanocrystallization tuning of structural, thermoelectric and electrical properties of SrTiO3-doped vanadate glasses

Published: August 2024

Abstract
Glass-ceramic nanocrystals (GCNs) were obtained by annealing parent SrTiO3-V2O5 (SV) glasses prepared using the melt-quenching technique at the crystallization temperature, Tc. The amorphous nature and glassy behavior of the quenched glasses were confirmed by XRD, DSC and FTIR spectroscopy. In the heat-treated samples, the crystal size was found to range from 40 to 80 nm for all studied samples. It was observed that as the SrTiO3 content in the GCNs increased, density (d) steadily rose. The change of vanadium ions concentration(C) has the predominant role for changing Seebeck coefficient in both glass and GCNs samples. The nanocrystallization process at temperatures close to the onset of Tc, lasting for one hour, notably increased the electronic conductivity of the initial glasses. Consequently, the modification in nanostructure resulted in enhanced conductivity. In comparison to the original glasses, the final materials demonstrated significantly improved electrical conductivity. The accumulation of V4+-V5+ pairs at the formed interlayer zones between nanocrystallites and the glassy phase is accountable for electron hopping in the current system, which is markedly higher than in the glassy matrix. The formed nanocrystallites play a crucial role in augmenting the conductivity of such nanomaterials. The maximum obtained value of the power factor (PF) is 0.9 × 10−4 mW/mk2 for the glass sample (x = 20) reflecting a very low thermoelectric power conversion efficiency while in GCNs, the PF values were well-enhanced to 0.6 mW/m.K2 at x = 20.
Gravitational waves from more attractive dark binaries
Authors: Bai Yang , Lu Sida , Orlofsky Nicholas 
Published: August 2024

Abstract
The detection of gravitational waves (GWs) has led to a deeper understanding of binaries of ordinary astrophysical objects, including neutron stars and black holes. In this work, we point out that binary systems may also exist in a dark sector with astrophysical-mass macroscopic dark matter. These “dark binaries”, when coupled to an additional attractive long-range dark force, may generate a stochastic gravitational wave background (SGWB) with a characteristic spectrum different from ordinary binaries. We find that the SGWB from planet-mass dark binaries is detectable by space- and ground-based GW observatories. The contribution to the SGWB today is smaller from binaries that merge before recombination than after, avoiding constraints on extra radiation degrees of freedom while potentially leaving a detectable GW signal at high frequencies up to tens of GHz.
Primordial monopoles, black holes and gravitational waves
Authors: Moursy Ahmad , Shafi Qaisar 
Published: August 2024

AbstractWe show how topologically stable superheavy magnetic monopoles and primordial black holes can be generated at observable levels by the waterfall field in hybrid inflation models based on grand unified theories. In SU(5) ×U(1)χgrand unification, the monopole mass is of order 4 × 1017GeV, and it carries a single unit (2π/e) of Dirac magnetic charge as well as screened color magnetic charge. The monopole density is partially diluted to an observable value, and accompanied with the production of primordial black holes with mass of order 1017–1019g which may make up the entire dark matter in the universe. The tensor to scalar ratioris predicted to be of order 10-5–10-4which should be testable in the next generation of CMB experiments such as CMB-S4 and LiteBIRD. The gravitational wave spectrum generated during the waterfall transition is also presented. The observed baryon asymmetry can be explained via leptogenesis.

Published: August 2024

Abstract
The accelerated expansion of the Universe has sparked significant interest in the mysterious concept of dark energy within cosmology. Various theories have been proposed to explain dark energy, and many models have been developed to understand its origins and properties. This research explores cosmic expansion using the Polytropic Gas (PG) approach, which combines Dark Matter (DM) and Dark Energy (DE) into a single mysterious fluid. We used the principles of general relativity and built our model within the homogeneous and isotropic framework of Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime. We revised the Original Polytropic Gas (OPG) model to expand its applicability beyond the OPG, to the ΛCDM model. Our model's parameters were carefully adjusted to reflect key cosmological features of the variable PG approach. To validate our model, we performed a Markov chain Monte Carlo analysis using recent Supernova data from the Pantheon+ survey, 36 observational

data points, 162 Gamma-Ray Bursts, and 24 binned Quasars distance modulus data. The AIC and BIC criteria indicate that our model is slightly preferred over the ΛCDM model based on observational data. We also tested our model with

data, Supernova, Gamma-Ray Bursts, and Quasars and found that it exhibits a transition from a quintessential to phantom regime. The Polytropic dark fluid model (PDFM) is a promising candidate that effectively addresses the interplay between cosmic acceleration and dark energy.

Abstract
In order to extend the enhanced D-Alpha H-mode to future devices, it is crucial to understand the properties of the main signature of this regime, the quasicoherent mode (QCM), that likely clamps the pressure gradient below the ideal magnetohydrodynamic limit. The turbulent character of the QCM is investigated with scanning probes in ASDEX Upgrade. Analysis reveals the multi-faced character of the mode that spans both the confined region (where the radial electric field is negative) and the near scrape-off layer (SOL) (where it is positive). Fluctuations of density and potential at the QCM frequency are more anti-correlated towards the confined region, which is a fingerprint of electromagnetic instabilities, while they become more correlated in the SOL, as expected for a drift-wave, inducing cross-field transport across the separatrix.

Abstract
The oil used in transformers is still using mineral oil, even though mineral oil derived from petroleum will be exhausted, non-renewable, non-degradable, toxic, not environmentally friendly. In this study, researchers used macadamia oil to determine the breakdown voltage value. This oil is oil derived from plants, its existence will always exist, can be renewed, can be decomposed again, non-toxic, and environmentally friendly. The value of the breakdown voltage, is the voltage limit that makes the transformer components submerged in oil connected, the oil no longer functions as an insulator. the test was carried out using an OTS 100 AF device with an electrode distance of 2.5 mm using a mushroom electrode referring to the IEC standard. The test is carried out at a temperature of 50 °C – 60 °C where this temperature is the temperature when the transformer operates. from the test results obtained a value of 57.60 kV, where this value has exceeded the standard and can be used at a network voltage of 170 kV.

Abstract
Wind power plant is one of the potential sources of electricity to be developed. Due to its height, the Base Transceiver Station (BTS) tower has a possibility for the wind turbine tower. This study aims to analyze whether the BTS tower can still stand sturdy when the wind turbine load is added. This research is related to the analysis of the value of von Mises stress, displacement, and safety factors. Furthermore, a comparison will be made between the results of the analysis with the maximum limit of these factors to determine the feasibility of the BTS tower. The result of this research is that none of these three factors cross the boundaries of the material used in the BTS tower. It can be concluded that the BTS tower when the wind turbine load is added can still stand strong and technically safe.

Abstract
This study aims to determine the optimum coagulant dose and optimum mixing time from the use of trembesi seeds, tamarind seeds, and moringa seeds as biocoagulants in removing turbidity, TSS, BOD, and COD in a laboratory scale with variations in biocoagulant doses of 0, 10, 20, 30, 50, 70, 100, 500, 600, and 700 ppm, using coagulation speed of 200 rpm with variations of fast stirring time of 1, 2, and 3 minutes, and flocculation speed of 80 rpm with variations of slow stirring time of 15, 30, and 45 minutes. The results showed that the optimum biocoagulant dose of 500 ppm was able to remove max turbidity by 78%, 54%, and 69% for trembesi seed, tamarind seed, and moringa seed coagulants, respectively. The optimum fast mixing time is 2 minutes for trembesi seed and moringa seed coagulant, and 3 minutes for tamarind seed coagulant. Parameters BOD, COD, and TSS do not meet the quality standards of the Minister of Environment Regulation Number 5 of 2014. The speed of coagulation rotation in the reactor is 100 rpm for 1 minute and 20 rpm flocculation for 10 minutes. This study shows that the biocoagulants of trembesi seeds, tamarind seeds, and moringa seeds are effective as biocoagulants because they are able to remove >50% of the TSS parameter, but further research is needed regarding the potential of liquid waste effluent to become fertilizer.

Poincaré Laguerre–Gaussian (LG) modes which have so far neither been evaluated, nor their significance highlighted. The theoretical framework we adopt here is both novel and essential because it emphasises the crucial role played by the normally ignored axial components of the twisted light fields of these modes. We show that the inclusion of the axial field components enables the intrinsic properties of the Poincaré modes, notably their angular momentum, both spin and orbital as well as their helicity and chirality, to be determined. We predict significant enhancements of the intrinsic properties of these modes when compared with those due to the zero order LG modes. In particular, we show that higher order LG Poincaré modes exhibit super-chirality and, significantly so, even in the case of the first order m = 1.
