description: We present waveform observations of electromagnetic lower hybrid and whistler waves with f_ci << f < f_ce downstream of four supercritical interplanetary (IP) shocks using the Wind search coil magnetometer. The whistler waves were observed to have a weak positive correlation between \partialB and normalized heat flux magnitude and an inverse correlation with T_eh/T_ec. All were observed simultaneous with electron distributions satisfying the whistler heat flux instability threshold and most with T_{perp,h}/T_{para,h} > 1.01. Thus, the whistler mode waves appear to be driven by a heat flux instability and cause perpendicular heating of the halo electrons. The lower hybrid waves show a much weaker correlation between \partialB and normalized heat flux magnitude and are often observed near magnetic field gradients. A third type of event shows fluctuations consistent with a mixture of both lower hybrid and whistler mode waves. These results suggest that whistler waves may indeed be regulating the electron heat flux and the halo temperature anisotropy, which is important for theories and simulations of electron distribution evolution from the sun to the earth.

description: The origin of large-scale magnetic fields in cosmic structures and the intergalactic medium is still poorly understood. We explore the effects of non-minimal couplings of electromagnetism on the cosmological evolution of currents and magnetic fields. In this context, we revisit the mildly non-linear plasma dynamics around recombination that are known to generate weak magnetic fields. We use the covariant approach to obtain a fully general and non-linear evolution equation for the plasma currents and derive a generalised Ohm law valid on large scales as well as in the presence of non-minimal couplings to cosmological (pseudo-)scalar fields. Due to the sizeable conductivity of the plasma and the stringent observational bounds on such couplings, we conclude that modifications of the standard (adiabatic) evolution of magnetic fields are severely limited in these scenarios. Even at scales well beyond a Mpc, any departure from flux freezing behaviour is inhibited.

THE ART MOTIFS ON EARLY HARAPPAN POTTERY FROM HARYANA
Creators: name: Dr. Jagpal Mann
Publisher: name: Zenodo
Year: 2023

description: The subject matter of the present study is on the various trends of pottery and its associated cultures of Haryana. The study of pottery from the excavated and other non-excavated sites in this region has enabled us to understand the settlement pattern of the Harappan cultures. Thus the study of pottery has once again helped us in understanding the settlement pattern of the Harappan cultures in Haryana. The most distinctive item in Early-Harappan assemblage is the pottery. Pottery of this period has been divided into six fabrics i.e. A to F as noticed at Kalibangan in Rajasthan, is also found in the region under study. These wares are wheel made, well fired, of thin to thick fabric, red, pinkish, buff and grey in colour. Most of the vessels are painted with designs which include a large number of geometric patterns, such as horizontal bands, loops, wavy lines, cross hatched triangles and semicircles, horizontal and vertical chains as well as faunal and floral motifs. Some pots are decorated with incised patterns like way lines and criss-cross designs.

title: Rosengarten - die Vermittlung von geburtshelfenden Maßnahmen am Beispiel von Rösslins Lehrbuch "Der Swangern Frauwen und heba[m]men Rosegarten (Straßburg, Hagenau, 1513)"

description: Das Drucken und Kompilieren von Texten war die zentrale Kulturtechnik der frühen Neuzeit und wurde hauptsächlich von gelehrten Männern vorgenommen. Dem gegenüber war das Wissen über geburtshilfliche Techniken ein reines Erfahrungswissen und wurde nur durch Praxiserfahrung von Frau zu Frau weitergegeben. So stellte ich mir die Frage, wie es dazu kommen konnte, dass gerade dieses praktische Wissen verschriftlicht und zu einem solchen Verkaufsschlager – wie es der Rosengarten war – werden konnte. Die Literatur hat gezeigt, dass die Arbeit von Geburtshelferinnen im Mittelalter ungeregelt war. So war die Geburtshilfe immer eine freiwillige Hilfeleistung von Nachbarinnen und erfahrenen Frauen, auf die Gefahr hinaus, bei Unfällen und Todesfällen als Schuldige angezeigt zu werden. Zumeist haben sich die Frauen gegenseitig beschuldigt und in weiterer Folge wurden viele sogar als Hexen verurteilt. Die städtische Obrigkeit veranlasste also eine Absicherung der Geburtshelferinnen und erhoben die Hebammen zu einer eigenen Berufsgruppe. Diese hatten in weiterer Folge eine praktische und theoretische Ausbildung zu durchlaufen, welche mit einer Prüfung beim Stadtarzt endete. Für diese Schritte war es notwendig, ein Lehrbuch für Hebammen – den Rosengarten – vorzulegen. Dieses beinhaltete neben allen der Zeit entsprechenden Topoi auch einen Rezeptteil – welche Mittel nun wirklich von der Hebamme verabreicht werden durften – und die genaue Beschreibung der Vorgehensweise der Hebamme in allen möglichen Fällen vor, während und nach der Geburt. Für die Entstehung des Lehrbuches war es also notwendig, Gelehrtenwissen mit praktischem Wissen zu vereinen. Der Erfolg des Buches gründet demnach auf der Verbindung von praktischen Erfahrungswissen und Gelehrtenwissen, der schnellen Verbreitung mittels Buchdrucks und der dadurch entstandenen Nutzbarkeit des Buches für die breite Gesellschaft.

description: This paper is the first of a series considering the properties of distribution of nearby galaxies in the low density regions. Among 7596 galaxies with radial velocities V_{LG}<3500 km/s, absolute magnitudes M_K15 degr there are 3168 field galaxies (i.e. 42%) that do not belong to pairs, groups or clusters in the Local universe. Applying to this sample the percolation method with a radius of r_0=2.8 Mpc, we found 226 diffuse agglomerates with n>=4 number of members. The structures of eight most populated objects among them (n>=25) are discussed. These non-virialized agglomerates are characterized by a median dispersion of radial velocities of about 170 km/s, the linear size of around 6 Mpc, integral K-band luminosity of 3*10^{11} L_sun, and a formal virial-mass-to-luminosity ratio of about 700 M_sun/L_sun. The mean density contrast for the considered agglomerates is only

description: In the stoichiometric Fe-pnictides the same d-electrons form the local moments and participate in the metallic conductivity. In the manuscript the emergence of the magnetic moments on the Fe-sites, their interaction with the itinerant electrons are studied in the paramagnetic phase at the different relations between the onsite Coulomb repulsion and the intraatomic Hund's exchange. The energy of the local center that is due to its interaction with the conduction electrons is calculated exactly. It is found that the spin density wave transition is controlled by the RKKY interactions between the centers rather than by the nesting mechanism. In the paramagnetic phase the electrons scatter on the randomly oriented moments. The calculated inverse mean free time provides the interpretation for few available experimental data on the conductivity. The multi-band structure of the energy spectrum in iron pnictides is taken into account.

description: Abstract
Children are the future of nation. It is they for whose way forward we build and design the nation. These children who are to be strong pillars of nation are made to become maculated and they are deprived of their childhood as they are forced to work. Not only loosing childhood but also affects their physical and mental development, they become unrealised of their ability and the dignity. They are immature enough to participate in excessively long and heavy work. There are many other inter-linked factors contributing to the prevalence of child labour. Child labour is both a cause and consequence of poverty. Household poverty forces children into the labour market to earn money. Some perform child labour to supplement family income while many also are in it for survival. They miss out on an opportunity to gain education, further perpetuating household poverty across generations, slowing the economic growth and social development.

description: In some communication networks, such as passive RFID systems, the energy used to transfer information between a sender and a recipient can be reused for successive communication tasks. In fact, from known results in physics, any system that exchanges information via the transfer of given physical resources, such as radio waves, particles and qubits, can conceivably reuse, at least part, of the received resources. This paper aims at illustrating some of the new challenges that arise in the design of communication networks in which the signals exchanged by the nodes carry both information and energy. To this end, a baseline two-way communication system is considered in which two nodes communicate in an interactive fashion. In the system, a node can either send an "on" symbol (or "1"), which costs one unit of energy, or an "off" signal (or "0"), which does not require any energy expenditure. Upon reception of a "1" signal, the recipient node "harvests", with some probability, the energy contained in the signal and stores it for future communication tasks. Inner and outer bounds on the achievable rates are derived. Numerical results demonstrate the effectiveness of the proposed strategies and illustrate some key design insights.

description: We consider the general theoretical framework to study exclusive double diffractive events (EDDE). It is a powerful tool to study the picture of the $pp$ interaction. Basic kinematical and dynamical properties of the process, and also normalization of parameters via standard processes like the exclusive vector meson production (EVMP), are considered in detail. As an example, calculations of the cross-sections in the model with three pomerons for the process $p+p\to p+M+p$ are presented for Tevatron and LHC energies.

Revisiting Theories with Enhanced Higgs Couplings to Weak Gauge Bosons

description: Based on recent LHC Higgs analyses and in anticipation of future results we revisit theories where Higgs bosons can couple to weak gauge bosons with enhanced strength relative to the Standard Model value. Specifically, we look at the Georgi-Machacek model and its generalizations where higher "spin" representations of SU(2)_L break electroweak symmetry while maintaining custodial SU(2). In these theories, there is not only a Higgs-like boson but partner Higgs scalars transforming under representations of custodial SU(2), leading to a rich phenomenology. These theories serve as a consistent theoretical and experimental framework to explain enhanced couplings to gauge bosons, including fermiophobic Higgses. We focus on the phenomenology of a neutral scalar partner to the Higgs, which is determined once the Higgs couplings are specified. Depending on the parameter space, this partner could have i) enhanced fermion and gauge boson couplings and should be searched for at high mass (> 600 GeV), ii) have suppressed couplings and could be searched for at lower masses, where the Standard Model Higgs has already been ruled out, and iii) have fermiophilic couplings, where it can be searched for in heavy Higgs and top resonance searches. In the first two regions, the partner also has substantial decay rates into a pair of Higgs bosons. We touch briefly on the more model-dependent effects of the nontrivial SU(2)_C multiplets, which have exotic signals, such as a doubly-charged Higgs. We also discuss how the loop induced effects of these scalars tend to reduce the Higgs decay rate to photons, adding an additional uncertainty when extracting the couplings for the Higgs boson.

THE EFFECT OF THE MUDRA YOJANA ON THE ADVANCEMENT OF WOMEN'S RIGHTS IN HARYANA
Creators: name: Ankita Mehra
Publisher: name: Zenodo
Year: 2023

description: The Micro Units Development and Refinance Agency (MUDRA) Yojana, which was introduced by the Government of India in 2015, serves as a significant financial inclusion initiative with the objective of enhancing the growth of micro and small firms. This study paper focuses on the state of Haryana, examining the program's effects on the promotion of women's rights and economic empowerment for women entrepreneurs. The study employs a comprehensive research technique that encompasses the examination of government statistics, field surveys, and personal interviews with women recipients. As a result, it reveals a complex depiction. The MUDRA Yojana has undoubtedly played a significant role in promoting women's economic autonomy, stimulating entrepreneurial activities, and enhancing self-confidence. However, the programme does present some problems. Significant challenges persist in the form of insufficient knowledge, restricted availability of financial literacy programmes, and deeply ingrained social restrictions. This study emphasises the need of adopting a comprehensive strategy that includes policy reform, awareness campaigns, and cultural change in order to fully realise the transformational impact of MUDRA Yojana for women in Haryana. By engaging in this action, it makes a valuable contribution to the wider conversation around financial inclusion, the rights of women, and the promotion of economic empowerment within the context of India.

description: Ultra-deep WFC3/IR observations on the HUDF from the HUDF09 program revealed just one plausible z~10 candidate UDFj-39546284. UDFj-39546284 had all the properties expected of a galaxy at z~10 showing (1) no detection in the deep ACS+WFC3 imaging data blueward of the F160W band, exhibiting (2) a blue spectral slope redward of the break, and showing (3) no prominent detection in deep IRAC observations. The new, similarly deep WFC3/IR HUDF12 F160W observations over the HUDF09/XDF allow us to further assess this candidate. These observations show that this candidate, previously only detected at ~5.9 sigma in a single band, clearly corresponds to a real source. It is detected at ~5.3 sigma in the new H-band data and at ~7.8 sigma in the full 85-orbit H-band stack. Interestingly, the non-detection of the source (<1 sigma) in the new F140W observations suggests a higher redshift. Formally, the best-fit redshift of the source utilizing all the WFC3+ACS (and IRAC+K-band) observations is 11.8+/-0.3. However, we consider the z~12 interpretation somewhat unlikely, since the source would either need to be ~20x more luminous than expected or show very high-EW Ly-alpha emission (which seems improbable given the extensive neutral gas prevalent early in the reionization epoch). Lower-redshift solutions fail if only continuum models are allowed. Plausible lower-redshift solutions require that the H-band flux be dominated by line emission such as Halpha or [OIII] with extreme EWs. The tentative detection of line emission at 1.6 microns in UDFj-39546284 in a companion paper suggests that such emission may have already been found.

title: Palynologische Untersuchungen der jahreszeitlichen Veränderungen der von Apis mellifera gesammelten Pollendiversität
Creators: name: Suess, Lisa
Year: 2024

description: Apis mellifera tragen im Zuge ihrer Sammelflüge Pollen der Umgebungsvegetation in den Bienenstock ein. Somit können anhand dieses Pollens Rückschlüsse auf das Sammelverhalten der Bienen gezogen werden. Dabei kann bereits die Farbe der Polleneinheiten Hinweise auf die darin enthaltenen Pollentaxa liefern. Die Anzahl der Polleneinheiten und unterschiedlichen Pollentaxa spiegeln dabei die jahreszeitlichen Veränderungen des Sammelverhaltens der Bienen sowie der Vegetation wider. Insgesamt wurden 8 980 Polleneinheiten von Apis mellifera Völkern zweier verschiedener Standorte (Wien Althangrund/Naturraum Carnuntum) zu fünf verschiedenen Zeitpunkten von Oktober 2022 bis Juni 2023 mittels Pollenfallen entnommen. Im Rahmen der anschließenden palynologischen Analyse wurden die Polleneinheiten gezählt, farblich sortiert und die darin enthaltenen Pollentaxa mittels licht- und rasterelektronenmikroskopischer Aufnahmen bestimmt. Insgesamt konnten pro Probe zwischen 307 und 3 155 Polleneinheiten entnommen, 3-11 Farben (x ̅ = 8±2.87) zugeordnet und 9-18 Pollentaxa (x ̅ = 13±3.54) bestimmt werden. Dabei konnte ein Zusammenhang zwischen der Anzahl der Farben, Polleneinheiten und Pollentaxa erkannt werden. Je mehr Polleneinheiten die Proben aufwiesen, desto mehr Farben und Taxa konnten identifiziert werden. Außerdem spiegeln die identifizierten Taxa nicht nur die Vegetation des Standortes wider, sondern bieten auch einen Einblick über die Veränderungen des Verhaltens des Bienenvolkes im jahreszeitlichen Rhythmus.
description: Apis mellifera collect pollen from the surrounding vegetation during its foraging trip and carry it into the nest. This pollen can therefore be used to draw conclusions about the bees' food collection behaviour. The colour of the pollen units can already provide clues as to the pollen taxa they contain. The number of pollen units and different pollen taxa reflect the seasonal changes in the bees' foraging behaviour and the vegetation. The pollen units were collected in pollen traps from colonies of Apis mellifera situated in two different locations (Wien Althangrund/Naturraum Carnuntum) at five different times from October 2022 to June 2023. As part of the subsequent palynological analysis, the pollen units were counted and sorted by colour, and the pollen taxa they contained were determined using light microscopy and scanning electron microscopy. In total, between 307 and 3 155 pollen units were collected per sample, 3-11 colours (x ̅ = 8±2.87) were classified and 9-18 pollen taxa (x ̅ = 13±3.54) were identified. A correlation between the number of colours, pollen units and pollen taxa could be recognized. The more pollen units the samples had, the more colours and taxa could be identified. In general, the identified taxa do not only reflect the vegetation of the location but also provide an insight into the changes in the behaviour of the bee colony in the seasonal rhythm.

description: We discuss various aspects of rigid supersymmetry within minimal N=1 off-shell supergravity using the old and new minimal formulations both in Lorentzian and Euclidean signatures. In particular, we construct all rigid supersymmetry backgrounds with a hypersurface orthogonal Killing vector. In the Lorentzian signature we show that AdS_4 provides a rigid supersymmetric background in both formulations albeit with different amounts of preserved supersymmetry. In the Euclidean signature we find new backgrounds of the old-minimal supergravity, including squashed four-spheres and a half-BPS version of flat space.

description: We establish a Mermin--Wagner type theorem for Gibbs states on infinite random Lorentzian triangulations (LT) arising in models of quantum gravity. Such a triangulation is naturally related to the distribution $\sf P$ of a critical Galton--Watson tree, conditional upon non-extinction. At the vertices of the triangles we place classical spins taking values in a torus $M$ of dimension $d$, with a given group action of a torus ${\tt G}$ of dimension $d'\leq d$. In the main body of the paper we assume that the spins interact via a two-body nearest-neighbor potential $U(x,y)$ invariant under the action of ${\tt G}$. We analyze quenched Gibbs measures generated by $U$ and prove that, for $\sf P$-almost all Lorentzian triangulations, every such Gibbs measure is ${\tt G}$-invariant, which means the absence of spontaneous continuous symmetry-breaking.

The internet of Things (IoT) plays a significant role in the world's major fields, including the economy, the medical field, weapon systems,social networks, and other potentialavenues for human interaction. The issues that the entire world is currently dealing with because of the pandemic are managed substantially by the IoT. In the Covid-19 scenario, systems based on the internet of things are used to monitor patients to preserve the protocols. In addition,a variety of web-based applications are acquired to interact with individuals and assist them in locating solutions to the numerous problems that have arisen during the lockdown period. Intensive research has been conducted using IoT and web services to address the potential challenges that arose during the Covid-19 conference. This paper presents an exploratory analysis of using the Internet of Things and Web Services to address pandemic challenges. In addition, we presenta statistical analysis that employs IoT devices to find solutions to current pandemic issues. Moreover, we depict how web services are currently used to gather data, identify, and provide precise information in each area or globally to handle pandemicconcerns
title: Frauen im Ersten Weltkrieg gehören erinnert - aber wie?
Creators: name: Horak, Roman
Year: 2024

description: Die vorliegende Arbeit setzt sich mit der Erinnerung an die Mitwirkung von Frauen als Angehörige der k.u.k. Streitkräfte beziehungsweise des Gefolges im Ersten Weltkrieg auseinander. Eine bedeutende Zahl an Frauen war in verschiedensten Funktionen an allen Schauplätzen des Krieges tätig, die Erinnerung daran wird kaum sichtbar. Die Studie untersucht verschiedene Erinnerungsorte und deren Kontext, welche schon durch die Zeitgenossen, in späteren Initiativen der Erinnerungskultur beziehungsweise in der Traditionspflege des Österreichischen Bundesheeres bis heute entstanden sind. Die Studie widerlegt die Annahme, dass Erinnerung an den Krieg grundsätzlich rein männlich sei. Die Analyse hat jedoch ergeben, dass Frauen als Kriegsteilnehmerinnen und Kriegstote nur bis zum Jahr 1933 gleichberechtigt erinnert wurden. Ab dem Austrofaschismus trat eine Transformation der Erinnerung ein. Diese war auf eine Militarisierung der Gesellschaft ausgerichtet und zweckbestimmt rein männlich codiert. Diese Veränderung beeinflusst die heutige Traditionspflege und unterstützt die Wahrnehmung des Krieges als vermeintlich rein männlichen Ort. Die Integration von Frauen an den Erinnerungsorten des Ersten Weltkrieges wird daher auch in der Forschung bislang nicht wahrgenommen. Dies führt aber gleichzeitig dazu, dass exotische Einzelfälle von Frauen im Militär bis heute in unreflektierter Weise wiedergegeben werden. Die vorgestellten Ergebnisse zeigen einen Handlungsbedarf auf, um eine zeitgemäße geschlechtergerechte Erinnerung an die Mitwirkung von Frauen im Dienst der Streitkräfte zu etablieren. Dies könnte den Bedarf für eine völlige Neugestaltung der bestehenden Erinnerungskultur im Militär begründen.

description: Recently observed increase of direct CP asymmetry in charm meson nonleptonic decays is difficult to explain within the SM. If this effect is induced by new physics, this might be investigated in other charm processes. We propose to investigate new CP violating effects in rare decays $D \to P \ell^+ \ell^-$, which arise due to the interference of resonant part of the long distance contribution and the new physics affected short distance contribution. Performing a model independent analysis, we identify as appropriate observables the differential direct CP asymmetry and partial decay width CP asymmetry. We find that in the most promising decays $D^+ \to π^+ \ell^+ \ell^-$ and $D_s^+ \to K^+ \ell^+ \ell^-$ the "peak-symmetric" and "peak-antisymmetric" CP asymmetries are strong phase dependent and can be of the order 1% and 10%, respectively.

description: Introdução: A hipertensão arterial (HTA) apresenta uma crescente prevalência mundial. Em Portugal tem uma prevalência de 36% e é a principal causa de morte. O controlo adequado é o melhor método na redução deste problema. Efetuou-se estudo para analisar o custo do tratamento da HTA, percebendo as diferenças entre doentes com e sem controlo. Adicionalmente, avaliaram-se assimetrias regionais, quanto ao cumprimento do cenário ideal: o melhor controlo da doença, pelo menor custo possível, no ambiente dos Cuidados de Saúde Primários. Métodos: Realizou-se estudo observacional pela recolha de dados públicos na plataforma “Bilhete de Identidade dos Cuidados de Saúde Primários”. Compararam-se dois indicadores: 352 – Custo com terapêutica do doente com Hipertensão Arterial e 353 – Custo com terapêutica do doente com Hipertensão Arterial controlada. Foi estudado o censo dos resultados nos anos de 2017 e 2018, no mês de Dezembro, em indicador flutuante e, para cada região de Saúde, numa amostra significativa e representativa dos ACeS. Realizou-se estatística paramétrica dada a normalidade dos dados: teste T de Student e ANOVA, definindo-se significado estatístico com p=0,001. Resultados: Em cada ano houve uma diferença significativa entre os dois indicadores, sendo o valor mais elevado na situação de controlo. O custo da terapêutica num doente com HTA controlada é significativamente maior do que na situação não controlada. Em €, em 2017, 78,14±7,98 vs. 90,05±9,12, com p<0,001; em 2018, 82,99±8,93 vs. 95,74±9,39, com p<0,001. No ano de 2018, mas não no de 2017, verificou-se diferença significativa no valor da HTA controlada por regiões, sendo mais elevado o valor no Alentejo, seguido de Centro e Algarve. Opondo-se, como de menor custo, ficaram as regiões Norte e Lisboa e Vale do Tejo. Discussão: Como o controlo da HTA apresenta um custo mais elevado, implica ponderar se as medidas não farmacológicas são insuficientes e/ou pouco valorizadas e implementadas na sociedade. Sendo os indicadores construídos em função do prescrito e não do comprado, as diferenças socioeconómicas podem ser um entrave à compra da medicação, que poderá não ser cumprida. As diferenças regionais poderão ser explicadas pelos contrastes de escolaridade, poder financeiro e distribuição do acesso e tipo de cuidados de saúde primários, bem como da idade e polifarmacoterapia. Conclusão: O custo da terapêutica da HTA controlada é significativamente maior que o da HTA não controlada. As diferenças regionais devem ser alvo da atenção de entidades competentes para a sua modificação.

description: Metallic Glasses are prone to fail mechanically via a shear-banding instability. In a remarkable paper Johnson and Samwer demonstrated that this failure enjoys a high degree of universality in the sense that a large group of metallic glasses appears to possess a yield-strain that decreases with temperature following a $-T^{2/3}$ law up to logarithmic corrections. In this Letter we offer a theoretical derivation of this law. We show that our formula fits very well simulational data on typical amorphous solids.

description: We investigate the magnetic properties of a range of low-dimensional ferromagnets using a combination of first-principles calculations and atomistic spin dynamics simulations. This approach allows us to evaluate the ground state and finite temperature properties of experimentally well characterized systems such as Co/Cu(111), Co/Cu(001), Fe/Cu(001) and Fe/W(110), for different thicknesses of the magnetic layer. We compare our calculated spin wave spectra with experimental data available in the literature, and find a good quantitative agreement. We also predict magnon spectra for systems for which no experimental data exist at the moment, and estimate the role of temperature effects.

description: Abstract
India has the potential to emerge as a prominent global financial center, with the banking industry playing a crucial role in enabling this transition. Following the implementation of liberalization policies, the industry has witnessed a substantial increase in the occurrence of mergers and acquisitions within the country. In order to generate value, mergers and acquisitions must result in enhanced financial performance for the merged entities. The objective of this study is to examine whether there has been a discernible enhancement in the CAMEL components of the banks under study following the merger. This study examines banks that have retained their identities subsequent to a merger instigated by the government of India. The merger in question was a component of the effort that was officially declared on August 30, 2019, and subsequently executed on April 1, 2020. The financial institutions under investigation in this research are Punjab National Bank and Canara Bank. The research indicates that there has been no significant improvement in the performance of banks under study subsequent to the merger.

description: The sequential form of a statement $\forallξ(B(ξ) \rightarrow \existsζA(ξ,ζ))$ is the statement $\forallξ(\forall n B(ξ_n) \rightarrow \existsζ\forall n A(ξ_n,ζ_n))$. There are many classically true statements of the first form whose proofs lack uniformity and therefore the corresponding sequential form is not provable in weak classical systems. The main culprit for this lack of uniformity is of course the law of excluded middle. Continuing along the lines of previous work by Hirst and Mummert, we show that if a statement of the first form satisfying certain syntactic requirements is provable in some weak intuitionistic system, then the proof is necessarily sufficiently uniform that the corresponding sequential form is provable in a corresponding weak classical system. Our results depend on Kleene's realizability with functions and the Lifschitz variant thereof.

description: Quantum fluctuations in an anharmonic superconducting circuit enable frequency conversion of individual incoming photons. This effect, linear in the photon beam intensity, leads to ramifications for the standard input-output circuit theory. We consider an extreme case of anharmonicity in which photons scatter off a small set of weak links within a Josephson junction array. We show that this quantum impurity displays Kondo physics and evaluate the elastic and inelastic photon scattering cross sections. These cross sections reveal many-body properties of the Kondo problem that are hard to access in its traditional fermionic version.

description: Aims. We report new results for the massive evolved and main sequence members of the young galactic cluster DBS2003 179. We determine the physical parameters and investigate the high-mass stellar content of the cluster, as well as of its close vicinity. Methods. Our analysis is based on ISAAC/VLT moderate-resolution (R\approx4000) infrared spectroscopy of the brightest cluster members. We derive stellar parameters for sixteen of the stellar members, using full non-LTE modeling of the obtained spectra. Results. The cluster contains three late WN or WR/LBV stars (Obj 4, Obj 15, and Obj 20:MDM32) and at least 5 OIf and 5 OV stars. According to the Hertzsprung-Russell diagram for DBS2003 179, the WR stars show masses above 85Msun, the OIf stars are between 40 and 80Msun, and the main sequence O stars are >20Msun. There are indications of binarity for Obj 4 and Obj 11, and Obj 3 shows a variable spectrum. The cluster is surrounded by a continuous protostar formation region most probably triggered by DBS2003 179. Conclusions. We confirm that DBS2003 179 is young massive cluster (2.5 10^4Msun) very close to the Galactic center at the distance of 7.9+-0.8 kpc.

description: Self-avoiding walks self-interacting via nearest neighbours (ISAW) and self-avoiding trails interacting via multiply-visited sites (ISAT) are two models of the polymer collapse transition of a polymer in dilute solution. On the square lattice it has been established numerically that the collapse transition of each model lies in a different universality class. It has been shown that by adding stiffness to the ISAW model a second low temperature phase eventuates and a more complicated phase diagram ensues with three types of transition that meet at a multi-critical point. For large enough stiffness the collapse transition becomes first-order. Interestingly, a phase diagram of a similar structure has been seen to occur in an extended ISAT model on the triangular lattice without stiffness. It is therefore of interest to see the effect of adding stiffness to the ISAT model. We have studied by computer simulation a generalised model of self-interacting self-avoiding trails on the square lattice with a stiffness parameter added. Intriguingly, we find that stiffness does not change the order of the collapse transition for ISAT on the square lattice for a very wide range of stiffness weights. While at the lengths considered there are clear bimodal distributions for very large stiffness, our numerical evidence strongly suggests that these are simply finite-size effects associated with a crossover to a first-order phase transition at infinite stiffness.
