description: In 2023, two Mw>7.5 earthquakes struck the East Anatolian Fault, Türkiye, causing more slip than expected. Such superevents could be part of a supercycle1,2, wherein the likelihood of a large earthquake is determined by accumulated strain rather than time since past earthquakes3. Here, we focus on how supercycles work. To do so, we examined the last four strong sequences along the East Anatolian Fault and discovered progressively younger and nonuniform earthquakes moving southwestward. This pattern corresponds to a general progression and dispersion of seismic ruptures southwestward. We use this pattern as a proxy to understand the mechanism of at least two major supercycles identified over the last two millennia. The supercycles evolved from the northeast, spreading southwestward with an increasing number of earthquakes. Earthquakes to the northeast are spatially and kinematically well channelized along the main fault, efficiently translating slip toward the southwest, where dispersed and kinematically nonuniform earthquakes are triggered by the push from the northeast until a new supercycle restarts from the northeast. To advance our understanding of earthquake occurrences that go beyond individual events, the next step is to examine seismic slip channeling elsewhere.

description: This paper discusses new simulation algorithms for stochastic chemical kinetics that exploit the linearity of the chemical master equation and its matrix exponential exact solution. These algorithms make use of various approximations of the matrix exponential to evolve probability densities in time. A sampling of the approximate solutions of the chemical master equation is used to derive accelerated stochastic simulation algorithms. Numerical experiments compare the new methods with the established stochastic simulation algorithm and the tau-leaping method.

Ultrafast Charge Separation and Nongeminate Electron-Hole Recombination in Organic Photovoltaics

description: The mechanism of electron-hole separation in organic solar cells is currently hotly debated. Recent experimental work suggests that these charges can separate on extremely short timescales (<100 fs). This can be understood in terms of delocalised transport within fullerene aggregates, which is thought to emerge on short timescales before vibronic relaxation induces polaron formation. However, in the optimal heterojunction morphology, electrons and holes will often re-encounter each other before reaching the electrodes. If such charges trap and cannot separate, then device efficiency will suffer. Here we extend the theory of ultrafast charge separation to incorporate polaron formation, and find that the same delocalised transport used to explain ultrafast charge separation can account for the suppression of nongeminate recombination in the best devices.

Phenomenology of the Inert (2+1) and (4+2) Higgs Doublet Models

description: We make a phenomenological study of a model with two inert doublets plus one Higgs doublet (I(2+1)HDM) which is symmetric under a Z$_2$ group, preserved after Electro-Weak Symmetry Breaking (EWSB) by the vacuum alignment $(0,0,v)$. This model may be regarded as an extension to the model with one inert doublet plus one Higgs doublet (I(1+1)HDM), by the addition of an extra inert scalar doublet. The neutral fields from the two inert doublets provide a viable Dark Matter (DM) candidate which is stabilised by the conserved $Z_2$ symmetry. We study the new Higgs decay channels offered by the scalar fields from the extra doublets and their effect on the Standard Model (SM) Higgs couplings, including a new decay channel into photon(s) plus missing energy, which distinguishes the I(2+1)HDM from the I(1+1)HDM. Motivated by Supersymmetry, which requires an even number of doublets, we then extend this model into a model with four inert doublets plus two Higgs doublets (I(4+2)HDM) and study the phenomenology of the model with the vacuum alignment $(0,0,0,0,v,v)$. This scenario offers a wealth of Higgs signals, the most distinctive ones being cascade decays of heavy Higgs states into inert ones. Finally, we also remark that the smoking-gun signature of all the considered models is represented by invisible Higgs decays into the lightest inert Higgs bosons responsible for DM.

description: In present work, we report a facile fabrication process to improve the photoelectrochemical (PEC) performance of ZnO-based photoelectrodes. To achieve this, Cu2O thin films are deposited on Cu substrates. Then / semiconductors materials are chemically vapour deposited on the Cu2O thin film. The fabricated photoelectrodes have been systematically studied in detail by various characterization techniques such as Xrd, Ftir and photoelectrochemical analysis. Composite of the fabricated photoelectrodes are investigated through X-ray diffraction analysis. To evaluate the PEC performance of the fabricated photoelectrodes, the measurement is performed using a two-electrode system in Sodium Chloride electrolyte solution under stimulated light illumination. Photocurrent measurements show that the // based photoelectrode has improved PEC performance compared with the pure Cu2O photoelectrode. The photocurrent density of // photoelectrode (0.70mA) is ~5 times higher than the photoelectrodes based on pristine Cu2O (0.13mA). The enhanced PEC performance of // photoelectrode is attributed to the excellent light absorption properties of Cu2O and excellent catalytic and charge transport properties of /. Experimental results show that the proposed functional materials have a great potential PEC application and solar H2 generation.

description: Highlights from Brookhaven National Laboratory (BNL) and experiments at the BNL Relativistic Heavy Ion Collider (RHIC) are presented for the years 2011--2013. This review is a combination of lectures which discussed the latest results each year at a three year celebration of the 50th anniversary of the International School of Subnuclear Physics in Erice, Sicily, Italy. Since the first collisions in the year 2000, RHIC has provided nucleus-nucleus and polarized proton-proton collisions over a range of nucleon-nucleon c.m. energies from 7.7 to 510 GeV with nuclei from deuterium to uranium, most often gold. The objective was the discovery of the Quark Gluon Plasma, which was achieved, and the measurement of its properties, which were much different than expected, namely a `perfect fluid' of quarks and gluons with their color charges exposed rather than a gas. Topics including quenching of light and heavy quarks at large transverse momentum, thermal photons, search for a QCD critical point as well as measurements of collective flow, two-particle correlations and $J/Ψ$ suppression are presented. During this period, results from the first and subsequent heavy ion measurements at the Large Hadron Collider (LHC) at CERN became available. These confirmed and extended the RHIC discoveries and have led to ideas for new and improved measurements.

description: We present microscopic investigations on the two-dimensional arrangement of cobalt phthalocyanine molecules on a graphite (HOPG) substrate in the low coverage regime. The initial growth and ordering of molecular layers is revealed in high resolution scanning tunneling microscopy (STM). On low coverages single molecules orient mostly along one of the substrate lattice directions, while they form chains at slightly higher coverage. Structures with two different unit cells can be found from the first monolayer on. A theoretical model based on potential energy calculations is presented, which relates the two phases to the driving ordering forces.

Based on these spectra and spectral data hexa coordinated geometries were assigned for the synthesized mixed ligand metal (II) complexes. Antimicrobial activity of the mixed ligand Mn(II), Ni(II), Cu(II) complexes with respect to the Schiff base against two gram positive (Staphylococcus aureus and Bacillus cereus) and two were gram negative (Escherichia coli and Klebsiella pneumoniae) were conducted to assess their antibacterial activities. The Schiff base along with the mixed ligand complexes exhibited very significant responses for gram positive and negative bacterial samples though maximum inhibition zone was produced by Ni(II) complex while the minimum inhibition zone was produced by Cu(II) complex in plates of Staphylococcus aureus.

description: After showing four outbursts spaced by $\sim 1$ year from 2009 to 2012, the hyper luminous X-ray source ESO 243-49 HLX-1, currently the best intermediate mass black hole (IMBH) candidate, showed an outburst in 2013 delayed by more than a month. In Lasota et al. (2011), we proposed that the X-ray lightcurve is the result of enhanced mass transfer episodes at periapsis from a donor star orbiting the IMBH in a highly eccentric orbit. In this scenario, the delay can be explained only if the orbital parameters can change suddenly from orbit to orbit. To investigate this, we ran Newtonian smooth particle hydrodynamical simulations starting with an incoming donor approaching an IMBH on a parabolic orbit. We survey a large parameter space by varying the star-to-BH mass ratio ($10^{-5}-10^{-3}$) and the periapsis separation $r_p$ from 2.2 to $2.7~r_t$ with $r_t$, the tidal radius. To model the donor, we choose several polytropes ($Γ= 5/2,~n=3/2$; $Γ=3/2,~n=2$; $Γ=5/3,~n=2$ & $n=3$). Once the system is formed, the orbital period decreases until reaching a minimum. Then, the period tends to increase over several periapsis passages due to tidal effects and increasing mass transfer, leading ultimately to the ejection of the donor. The development of stochastic fluctuations inside the donor could lead to sudden changes in the orbital period from orbit to orbit with the appropriate order of magnitude of what has been observed for HLX-1. Given the constraints on the BH mass ($M_{\rm BH} > 10^4~M_\odot$) and assuming that HLX-1 is currently near a minimum in period of $\sim 1$ yr, the donor has to be a white dwarf or a stripped giant core. We predict that if HLX-1 is indeed emerging from a minimum in orbital period, then the period would generally increase with each passage, although substantial stochastic fluctuations can be superposed on this trend.

description: विहीर व कूपनलिका पुनर्भरणाची गरज : पाणी ही एक नैसर्गिक संपत्ती आहे. भूतलावरील सर्व जीवसृष्टीला पाण्याची गरज आहे. पावसाचे पाणी भूपृष्ठभागावर पडून जमिनीत मुरते. मुरणारे पाणी भूपृष्ठाखाली खोलवर जमिनीच्या काही थरांमध्ये साठते. अशा पाण्याच्या साठ्याला आपण भूजल असे म्हणतो. विहीरीद्वारे हा भूजलसाठा आपली पिण्याची, शेतीची व काही प्रमाणात औद्योगिक गरज भागवितो. वाढत्या लोकसंख्येमुळे पाण्याची गरज वाढत आहे. भूपृष्ठावर असलेले जलसाठे कमी /अपुरे पडत असल्यामुळे भूजल साठा वापरण्याचे प्रमाण वेगाने वाढत आहे. ज्याप्रमाणात भूजलसाठ्यात नैसर्गिकरित्या वाढ होत आहे. त्यापेक्षा जास्त प्रमाणात भूजलसाठा उपसला जात आहे. परिणामी भूजल पातळी दिवसेंदिवस खोल जात आहे. कूपनलिकेद्वारे काही ठिकाणी ५०० फुटापेक्षा जास्त खोलीवरून भूजल उपसण्यात येत आहे. भूजल साठ्याचा वाढण्याचा नैसर्गिक वेग कमी असल्याने कृत्रिमरित्या हा वेग वाढविण्याचे उपाय योजणे गरजेचे झाले आहे. विहीर पुनर्भरण व कूपनलिका पुनर्भरण हा त्यापैकी एक उपाय आहे. जमिनीमध्ये अनेक वेगवेगळे थर आढळतात. या थरांची जाडी, आकारमान वेगवेगळे आहे. मातीच्या थरातून पाणी मुरण्याचा वेग दर दिवसाला साधारणपणे २ सें.मी. असतो. मुरमाच्या थरातून पाणी वाहण्याचा हाच दर १० सें.मी. असू शकतो. ज्या खडकांना भेगा, फटी, सळ व सुक्ष्म छिद्रे असतात त्या खडकातून पाणी वाहण्याचा हाच दर २०० सें.मी. एवढा सुध्दा असू शकतो. या सर्वांचा एकत्रितपणे विचार केला असता पावसाचे पाणी जमिनीवर पडल्यापासून भूजलसाठ्यापर्यंत पोहचण्यास साधारणपणे एक महिना किंवा जास्त कालावधी लागतो. म्हणजेच नैसर्गिक भूजल भरणाचा वेग फार कमी आहे हे दिसून येते. पाणी उपसण्याचा सध्याचा आपला वेग भूजल भरणाच्या वेगापेक्षा जास्त आहे. यावरून विहीर पुनर्भरण हे किती महत्त्वाचे व गरजेचे आहे हे दिसून येईल.
विहीर पुनर्भरण म्हणजे काय..? पावसाचे पाणी विहीरीत सोडणे म्हणजे विहीर पुनर्भरण होय. यासाठी ओढा किंवा नाल्यातून वाहणारे पावसाचे पाणी, पावसाचा अपधाव यांचा वापर करता येतो. पावसाळ्यात विहीर भरल्याने विहीरीतील पाणी जमिनीत खोलवर मुरेल. ज्या जलथरातून पाणी उपसले गेले होते, त्या जलथरात विहीरीतील पाणी शिरते. पावसाळ्याच्या संपूर्ण हंगामात अशा प्रकारे पाणी भरलेल्या विहीरींच्या सर्वात जास्त खोलवर असलेल्या थरात भूजलसाठा पूर्ववत होऊ शकतो. विहीरीत गाळ मिश्रीत पाणी भरल्यास आणि विहीरीत गाळ असल्यास या सूक्ष्म भेगांतून / छिद्रांतून गाळयुक्त पाणी जल- थरात वाहतांना गाळामुळे ती छिद्रे / भेगा/फटी बंद पडण्याचा दाट धोका निर्माण होतो व जर ही छिद्रे बंद पडली तर विहीर बंद पडू शकते. म्हणून गाळविरहीत पाणी विहीरीत सोडणे अत्यंत महत्वाचे आहे.

description: There is mounting evidence that mechanical radio source feedback is important in galaxy evolution and in order to quantify this feedback, detailed models of radio source evolution are required. We present an extension to current analytic models that encompasses young radio sources with physical sizes on sub-kiloparsec scales. This work builds on an existing young source dynamical model to include radiative losses in a flat environment, and as such, is the best physically-motivated Compact Symmetric Object model to date. Results predict that young radio sources experience significant radiative loss on length scales and spectral scales consistent with observed Compact Steep-Spectrum sources. We include full expressions for the transition to self-similar expansion and present this complete model of radio source evolution from first cocoon formation to end of source lifetime around 10^8 years within the context of a simplified King profile external atmosphere.

At the moment, however, there are no data suggesting the better control of once-daily fixed (Fixed) over free doses in separate administrations combination therapy in hypertensives. In a population of 39 consecutive outpatient patients referred to the departmental Hypertension clinic of the University Hospital of Salerno Medical School with the first diagnosis of arterial hypertension, we tested the hypothesis that the Fixed achieve a better control of blood pressure than the Free combination. Patients were randomized to either strategy and after 3 months patients underwent a clinical assessment to evaluate the antihypertensive effect. The two groups, matched for anthropometric and clinical parameters, received Amlodipine (5-10 mg/daily) and Perindopril (5-10 mg/daily). Perindopril and Amlodipine doses did not significantly differ between the two groups. After 3 months BP control was improved in both groups and BP targets were similarly reached in both groups (SBP; Fixed: 61.54%; Free 69.23%; n.s. DPB; Fixed: 80.77%; Free 84.62%; n.s.). The reduction in systolic blood pressure was similar in both groups (Fixed:7.64±2.49%; Free: 7.81±4.00%, n.s.), while the reduction of diastolic blood pressure was greater in the Fixed group (Fixed: 14.22±2.03%; Free: 4.92±5.00%, p<0.05). Although both strategies are effective in reducing BP, the use of Fixed dose has an advantage in the reduction of BP. The present study does not allow to identify the mechanisms of this difference, which can be assumed to be due to the pharmacokinetics of the drugs administered in once-daily fixed combination.

description: The Sloan Digital Sky Survey (SDSS) Galaxy Zoo project has revealed a number of spectacular galaxies possessing Extended Emission-Line Regions (EELRs), the most famous being Hanny's Voorwerp galaxy. We present another EELR object discovered in the SDSS endeavor: the Teacup Active Galactic Nucleus (AGN), nicknamed for its EELR, which has a handle like structure protruding 15 kpc into the northeast quadrant of the galaxy. We analyze physical conditions of this galaxy with long-slit ground based spectroscopy from Lowell, Lick, and KPNO observatories. With the Lowell 1.8m Perkin's telescope we took multiple observations at different offset positions, allowing us to recover spatially resolved spectra across the galaxy. Line diagnostics indicate the ionized gas is photoionized primarily by the AGN. Additionally we are able to derive the hydrogen density from the [S II] 6716/6731 ratio. We generated two-component photoionization models for each spatially resolved Lowell spectrum. These models allow us to calculate the AGN bolometric luminosity seen by the gas at different radii from the nuclear center of the Teacup. Our results show a drop in bolometric luminosity by more than two orders of magnitude from the EELR to the nucleus, suggesting that the AGN has decreased in luminosity by this amount in a continuous fashion over 46,000 years, supporting the case for a dying AGN in this galaxy independent of any IR based evidence. We demonstrate that spatially resolved photoionization modeling could be applied to EELRs to investigate long time scale variability.

description: The α-amino phosphonates find a wide spectrum of applications in medicinal, industrial, and agricultural chemistry. The most simple and straight forward synthetic technique for the formation of α-amino phosphonates is the Kabachnik–Fields reaction (an MCR) which involves the one-pot, three-component coupling of an aldehyde or ketone (carbonyl compound), amine and phosphite ester. The development of computational approaches as another tool for determining the features of chemicals has been a content of intensive research. In the current research, the AutoDock 4.0 package was employed for docking synthetic compounds into a protein, cyclin-dependent kinase 2 with the flexible side chain of TYR15. Cyclin-dependent kinase 2 (CDK2) is a member of an extremely conserved family of protein kinases that regulate the eukaryotic cell cycle. The lowest energy poses obtained in docking simulations of dimethyl ((4-nitrophenyl)(phenylamino)methyl) phosphonate were attained with the CDK2 model. This inhibitor has investigated the chemical effects on conformational behavior of CDK2.

description: We investigate the diffusion of cosmic rays into molecular cloud complexes. Using the cosmic-ray diffusion formalism of Protheroe, et al. (2008), we examine how cosmic rays diffuse into clouds exhibiting different density structures, including a smoothed step-function, as well as Gaussian and inverse-$r$ density distributions, which are well known to trace the structure of star-forming regions. These density distributions were modelled as an approximation to the Galactic centre cloud G0.216+0.016, a recently-discovered massive dust clump that exhibits limited signs of massive star formation and thus may be the best region in the Galaxy to observe synchrotron emission from secondary electrons and positrons. Examination of the resulting synchrotron emission, produced by the interaction of cosmic ray protons interacting with ambient molecular matter producing secondary electrons and positrons reveals that, due to projection effects, limb-brightened morphology results in all cases. However, we find that the Gaussian and inverse-$r$ density distributions show much broader flux density distributions than step-function distributions. Significantly, some of the compact (compared to the $2.2''$ resolution, 5.3 GHz JVLA observations) sources show non-thermal emission, which may potentially be explained by the density structure and the lack of diffusion of cosmic rays into the cloud. We find that we can match the 5.3 and 20 GHz flux densities of the non-thermal source JVLA~1 and 6 from Rodr\'ıguez & Zapata (2014) with a local cosmic ray flux density, a diffusion coefficient suppression factor of $χ=0.1-0.01$ for a coefficient of $3\times10^{27}$ cm$^2$ s$^{-1}$, and a magnetic field strength of 470 $μ$G.

description: A heterogeneous magnetic HFe(SO4)2.4H2O-chitosan nano-composite (HFe(SO4)2.4H2O-Ch NCs) was designed and synthesized through a facile and economical two-steps procedure. The synthesized HFe(SO4)2.4H2O-Ch NCs was identified by XRD, EDX, FT-IR, VSM, SEM, TEM, and TGA techniques. The resulting HFe(SO4)2.4H2O-Ch NCs was applied as an efficient nano-catalyst in the green synthesis of coumarin derivatives through pechmann condensation under solvent-free conditions at 100 °C, and also with ultrasonic-assisted at 70 °C. High yields of the products, short reaction times, and mild reaction conditions were perceived in both methods. The ability of detachment, recycling, and reuse of the nano-catalyst was investigated under reaction conditions.
