description: The goal of this paper is to apply the method of Lagrangian descriptors to reveal the phase space mechanism by which a Caldera-type potential energy surface (PES) exhibits the dynamical matching phenomenon. Using this technique, we can easily establish that the non-existence of dynamical matching is a consequence of heteroclinic connections between the unstable manifolds of the unstable periodic orbits (UPOs) of the upper index-1 saddles (entrance channels to the Caldera) and the stable manifolds of the family of UPOs of the central minimum of the Caldera, resulting in the temporary trapping of trajectories. Moreover, dynamical matching will occur when there is no heteroclinic connection, which allows trajectories to enter and exit the Caldera without interacting with the shallow region of the central minimum. Knowledge of this phase space mechanism is relevant because it allows us to effectively predict the existence, and non-existence, of dynamical matching. In this work we explore a stretched Caldera potential by means of Lagrangian descriptors, allowing us to accurately compute the critical value for the stretching parameter for which dynamical matching behavior occurs in the system. This approach is shown to provide a tremendous advantage for exploring this mechanism in comparison to other methods from nonlinear dynamics that use phase space dividing surfaces.

description: It is shown that, contrary to what is normally expected, it is possible to have angular momentum effects on the geometry of space time at the laboratory scale, much bigger than the purely Newtonian effects. This is due to the fact that the ratio between the angular momentum of a body and its mass, expressed as a length, is easily greater than the mass itself, again expressed as a length.

description: The present study was conducted to isolate the causal agent of necrotic enteritis (NE) from broiler chickens. A total of 50 jejunal samples from necropsied broiler chickens were collected for isolation of Clostridium perfringens, the causal agent of NE. The novel method for isolation of Clostridium perfringens was stab culture in association with pouring of olive oil on the surface of the stab culture. The collected samples in nutrient broth were kept in a candle jar and incubated for 24 hrs at 37°C. For maintenance of anaerobic condition olive oil (2-3 cm) were poured on surface of culture broth in test tube. In Gram's staining, the morphology of the isolated bacteria was Gram-positive, rod-shaped, anaerobic, spore-forming single or paired in arrangement. The addition of olive oil on the surface of stab culture was effective for the growth of Clostridium perfringens. The characterization of Clostridium perfringens was then performed by other routine cultural study, staining procedure and different types of biochemical tests. The occurrence of necrotic enteritis was 8%.

description: In Shannon information theory the capacity of a memoryless communication channel cannot be increased by the use of feedback. In quantum information theory the no-cloning theorem means that noiseless copying and feedback of quantum information cannot be achieved. In this paper, quantum feedback is defined as the unlimited use of a noiseless quantum channel from receiver to sender. Given such quantum feedback, it is shown to provide no increase in the entanglement--assisted capacities of a memoryless quantum channel, in direct analogy to the classical case. It is also shown that in various cases of non-assisted capacities, feedback may increase the capacity of memoryless quantum channels.

description: Epidemiology of gastro-intestinal parasites of water buffaloes was investigated in Kurigram district of Bangladesh between November 2007 and October 2008 through coprological examination. A total of 236 water buffaloes were examined, among them 144 (61.02%) buffaloes were found infected with one or more species of gastro-intestinal parasites. Nine species of gastro-intestinal parasites were identified, of them four species were trematodes, namely, Paramphistomum cervi (29.24%), Fasciola gigantica (22.46%), Schistosoma indicum (1.27%), Schistosoma spindale (0.85%); three species were nematodes, namely, Toxocara vitulorum (2.54%), Strongyles (0.85%), Strongyloides sp. (0.42%) and two species were protozoa, namely, Eimeria sp. (3.39%) and Balantidium coli (37.29%). No cestode was detected. Among the gastro-intestinal parasites mixed infection was common. In this investigation, prevalence of parasites in relation to age, sex and seasonal dynamics was also studied. Significantly (p<0.01) higher prevalence of gastro-intestinal parasites was observed in rainy season followed by summer and winter seasons. Males and females were almost equally (odd ratio 1.08) susceptible to gastro-intestinal parasitic infection. In the age groups, young (< 2 to 5 years) were mostly (p<0.01) susceptible to gastro-intestinal parasites. In the present study, EPG (Egg/cyst Per Gram of Feces) was also determined. The range of EPG varied from 100-5000 among the identified parasites. The results of the present investigation revealed that the prevalence of gastro-intestinal parasites in buffaloes is very common and quite severe. It is imperative that integrated strategies and measures be taken to control gastrointestinal parasitic infections in buffaloes in kurigram district and elsewhere in Bangladesh.

description: We consider uplink power control in wireless communication when a large number of users compete over the channel resources. The CDMA protocol, as a supporting technology of 3G networks accommodating signal from different sources over the code domain, represents the orthogonal multiple access (OMA) techniques. With the development of 5G wireless networks, non-orthogonal multiple access (NOMA) is introduced to improve the efficiency of channel allocation. Our goal is to investigate whether the power-domain NOMA protocol can introduce performance improvement when the users interact with each other in a non-cooperative manner. It is compared with the CDMA protocol, where the fierce competition among users jeopardizes the efficiency of channel usage. In this work, we conduct analysis with an aggregative game model, and show the existence and uniqueness of an equilibrium strategy. Next, we adopt the social welfare of the population as the performance metric, which is the average utility achieved by the user population. It is shown that under the corresponding equilibrium strategies, NOMA outperforms CDMA by higher efficiency of channel access for uplink communications.

description: We investigate nuclear fragmentation in the central proton-nucleus and nucleus - nucleus collisions at the energies of LHC. We argue that within the semi-classical approximation because of fast increase with energy of cross sections of soft and hard interactions each nucleon is stripped in the average process off ``soft'' partons and fragments into a collection of leading quarks and gluons with large $p_t$. Valence quarks and gluons are streaming in the opposite directions when viewed in the c.m. of the produced system. The resulting pattern of the fragmentation of the colliding nuclei leads to an implosion of the quark and gluon constituents of the nuclei. The matter density produced at the initial stage in the nucleus fragmentation region is estimated to be $\geq$ 50 GeV/fm$^3$ at the LHC energies and probably $\geq$ 10 GeV/fm$^3$ at RHIC.

description: This study was designed to investigate the prevalence and pathology of mite infestation in the street dog at Dinajpur municipality area, Dinajpur, Bangladesh, during June to September, 2010 using simultaneous clinical and histopathological examination and identification. A total of 48 street dogs (27 male and 21 female) were examined, among them 30(62.5%) were infested with one or more species of mites. Two species of mites were identified as Sarcoptes scabiei var.canis and Demodex canis. The range of mites burden was 1-5 per square inch of heavily infested area. Mean mites burden was high in case of Sarcoptes scabiei var.canis (1.5±0.2) followed by Demodex canis (0.6±0.1). Prevalence was higher in the dog of 1-2 years of age (68.9%) than in the dog of >2-4 years of age (52.6%). Infestation of mite was significantly (p<0.05) higher in male (66.6%) than female (57.1%) dog. Mite infestation was more prevalent in the poor healthy dog (75.7%) than the normal healthy dog (33.3%). Prevalence of mites infestation was significantly (p<0.05) higher in back region (68.1%) followed by face and neck (66.6%) and abdomen (58.3%) and lowest in thigh and groin (40.0%). Grossly, alopecia, rough, dry leathery and corrugation of skin, erythema, pastules, crusts and pruritus were found. Microscopically, it was characterized by acanthosis, slight hyperkeratosis, formation of hyperplastic rete-pegs, destruction of dermis and epidermis, hyperplastic changes in sweat glands, sebaceous glands and hair follicular cells, pyogranuloma in papillary layer and hair follicles and infiltration of neutrophils, oeosinophils, lymphocytes and few macrophages. The results indicate that street dogs of Dinajpur municipality area are very much susceptible to mite infestation. The mite produces clinico- pathological effects on dog, which may be the serious threat to public health.

Frequency down conversion through Bose condensation of light

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose an experimental set up allowing to convert an input light of wavelengths about $1-2 μm$ into an output light of a lower frequency. The basic principle of operating relies on the nonlinear optical properties exhibited by a microcavity filled with glass. The light inside this material behaves like a 2D interacting Bose gas susceptible to thermalise and create a quasi-condensate. Extension of this setup to a photonic bandgap material (fiber grating) allows the light to behave like a 3D Bose gas leading, after thermalisation, to the formation of a Bose condensate. Theoretical estimations show that a conversion of $1 μm$ into $1.5 μm$ is achieved with an input pulse of about $1 ns$ with a peak power of $10^3 W$, using a fiber grating containing an integrated cavity of size about $500 μm \times 100 μm^2$.

description: This work presents new surface photometry and two-dimensional modeling of the light distribution of the Polar Ring Galaxy NGC 4650A, based on near-infrared (NIR) observations and high resolution optical imaging acquired during the Hubble Heritage program. The NIR and optical integrated colors of the S0 and the polar ring, and their scale parameters, are compared with those for standard galaxy morphological types. The polar structure appears to be a disk of a very young age, while the colors and light distribution of the host galaxy do not resemble that of a typical early-type system. We compare these observational results with the predictions from different formation scenarios for polar ring galaxies. The peculiarities of the central S0 galaxy, the polar disk structure and stellar population ages suggest that the polar ring galaxy NGC 4650A may be the result of a dissipative merger event, rather than of an accretion process.

description: An understanding of past, from which we learn, and present, through which we observe, population dynamics is necessary for development planning for a country. This paper studies this present facts of and past trends in population dynamics paying particular attention to the major demographic variables of population, fertility, mortality, and migration profiles in the last two decades with an assessment of various demographic data sources in Bangladesh. In doing so various literatures were reviewed and secondary data were generated mostly from international sources, like database of the United Nations, Population Reference Bureau, US Census Bureau etc., and partly from national sources, like population census, Bangladesh demographic and health survey etc., which are the major sources of demographic data for Bangladesh. The study observes that the demographic indicators of Bangladesh have shown considerable development during the last two decades. Though the population increased in size but growth showed a declining trend. The total fertility rate declined from 3.96 children per woman during 1990- 1995 to 2.36 during 2005-2010, and infant mortality and under-five mortality rates almost halved during the same period. Life expectancy at birth recently reached to 69 years from 56 years in 1990. Moreover, international outmigration showed an increasing trend with a very low rate for female.

description: Mott insulators under sufficiently strong spin-orbit coupling can display quantum spin liquid phases with topological order and fractional excitations. Quantum magnets with pure Kitaev spin exchange interactions can host a gapped quantum spin liquid with a single Majorana edge mode propagating in the counter-clockwise direction when a small positive magnetic field is applied. Here, we show how under a sufficiently strong positive magnetic field a topological transition into a gapped quantum spin liquid with two Majorana edge modes propagating in the clockwise direction occurs. The Dzyaloshinskii-Moriya interaction is found to turn the non-chiral Kitaev's gapless quantum spin liquid into a chiral one with equal Berry phases at the two Dirac points. Thermal Hall conductance experiments can provide evidence of the novel topologically gapped quantum spin liquid states predicted.

description: The study was undertaken to examine the socio-economic profiles of women participated in farms and rice mills activities; to examine contribution of women to household income which reducing their poverty; to identify the factors influencing the level of family income in farms and rice mills labourers; and to identify the problems and constraints of farms and rice mills. Bochagonj Upazila of Dinajpur district was selected purposively for the study considering the availability of large number of farm and rice mill labourers. Sixty samples of each category have been selected by random sampling procedure and primary data were collected by direct interview through a pre-tested survey schedule. The educational status, land holding and other household assets position were improved due to the women’s contribution to overall family income. Patterns of family expenditure remained same before and after the women involvement in farm and rice mill works but increased over time that indicated some significant changes in the level of poverty of the households. Age of the respondents, family size, land holding, number of earning members and respondents’ income contributed significantly to the variability of income and employment. Major problems were nature of the work and the variation in the salary level between male and female labourers. Finally, women contributed a small amount but a significant proportion of their family income and the socioeconomic status of the women farm and rice mill labourers should be improved through direct participation in income generating activities by reducing the male and female discriminations.

description: The fluidized bed drying principles for drying of tea in Bangladesh is thoroughly studied. The experiments were conducted to determine the drying curve, drying time, drying constant and dynamic equilibrium moisture contents of tea at the Bangladesh Tea Research Institute. Drying of tea in a fluidized bed dryer (Kilburn Vibro Fluid Bed Dryer) takes only 20 min for drying from an initial moisture content of 69.1% to a final moisture content of 2.8%. Temperatures of drying air were recorded to be 130°C at the inlet and 90°C at the outlet. The drying constant was found to be 31.05 h-1 and the dynamic equilibrium moisture contents were in the range of 18.3 to 2.0%. Finally the principle of fluidized bed drying was compared with the principle of conventional endless chain pressure type drying.

description: The Principal determination of the study was to fix the extent of environmental sentience among the different classes of industrial workers. A hundred ten workers were selected through purposive sampling technique from several industries in the region of Tangail district, Bangladesh. Among the selected workers, the female respondents were 37 in number and rests of the 73 were male. The workers were asked questions to appraise their level of understanding considering environment, environmental issues, and their persuasion to solve the different environmental problems. The determinations disclosed that, majority (91.8%) of the workers have approximately general conception about environment, idea about pollution of environmental constituents, Global warming and climate change awareness. From the view of most (85.5%) of the workers, the country is most vulnerable due to environmental pollution and not executing competent rules and ordinance along with public awareness.

description: An experimental small scale desalination system where solar energy as the main heat source was conducted in a remote area of Cox’s Bazar district of Bangladesh. In this investigation, the performance of three solar stills with transparent glass cover was studied. Treated sea water was given to the solar still and the quantity of distilled water from three solar stills was measured per day and the effectiveness of the stills was compared. The performance of these stills was checked for 20 days. The different parameters i.e. ambient temperature, Salinity, pH, Unionized NH3, Iron, NO2-N, Chlorine, DO and amount of distilled water were studied and analyzed. The average amount of water produced by the still (1) was 455 ml, still (2) was 394.75ml and still (3) was 339.25 ml. The total amount of water produced by the still (1) was 9100 ml, still (2) was 7895 ml and still (3) was 6785 ml. The average desalinated water were obtained 1.06 liter/m2 /day, 0.98 liter/ m2 /day and 0.95 liter/ m2 /day from still 1, 2 and 3 respectively.
Geometrical approach to light in inhomogeneous media

description: Electromagnetism in an inhomogeneous dielectric medium at rest is described using the methods of differential geometry. In contrast to a general relativistic approach the electromagnetic fields are discussed in three-dimensional space only. The introduction of an appropriately chosen three-dimensional metric leads to a significant simplification of the description of light propagation in an inhomogeneous medium: light rays become geodesics of the metric and the field vectors are parallel transported along the rays. The new metric is connected to the usual flat space metric diag[1,1,1] via a conformal transformation leading to new, effective values of the medium parameters leading to an effective constant value of the index of refraction n=1. The corresponding index of refraction is thus constant and so is the effective velocity of light. Space becomes effectively empty but curved. All deviations from straight line propagation are now due to curvature. The approach is finally used for a discussion of the Riemann-Silberstein vector, an alternative, complex formulation of the electromagnetic fields.

description: The main purpose of the study was to analyse the farmers’ communication exposure and knowledge in poultry farming. The research was conducted in three selected unions of Bhaluka upazila under Mymensingh district. Each of the six selected characteristics of poultry farmers namely age, education, family size, family education, farm size and organizational participation are the independent variables; while farmers’ exposure to communication media for poultry production and farmers’ knowledge on poultry were the two dependent variables. In case of farmers’ exposure to communication media for poultry production, majority of the farmers (54 percent) had low exposure to communication media, while 46 percent had medium exposure and none of them had high exposure. In the case of poultry farming knowledge, majority of the farmers (57 percent) had medium knowledge while 29 percent of them had low knowledge and only 14 percent had high knowledge. Tests of hypotheses indicated that education of the farmers was positively related to communication exposure for poultry production while the rest independent variables had no relationship with any of the dependent variables.

description: This study assessed the clinical efficacy of nirmatrelvir plus ritonavir (NMV-r) in treating patients with COVID-19 who have preexisting cardiovascular diseases (CVDs). Patients with underlying CVDs and COVID-19 were included from the TriNetX network. We employed a 1:1 propensity score matching to create two comparable cohorts: patients receiving NMV-r and those not receiving NMV-r. The primary outcome was the composite outcome of all-cause hospitalization or death within 30 days. Propensity score matching yielded two matched cohorts of 10,847 patients each. The composite outcomes of all-cause hospitalization or death within 30 days were 2.2% (239 patients) in the NMV-r cohort and 4.7% (512 patients) in the control cohort, indicating reduced risk in the NMV-r cohort (hazard ratio [HR], 0.475; 95% confidence interval [CI], 0407–0.533). The NMV-r cohort exhibited lower risks of all-cause hospitalization (HR, 0.525; 95% CI, 0.449–0.615) and mortality (HR, 0.113; 95% CI, 0.052–0.246) compared with the control group. A similar trend was observed across most of the subgroups. Our findings indicate that NMV-r to treat COVID-19 could reduce all-cause hospitalization and death in patients with CVDs.

description: We present measurements of the spectral properties for a total of 526,265 quasars, out of which 63% have continuum S/N$>3$ pixel$^{-1}$, selected from the fourteenth data release of the Sloan Digital Sky Survey (SDSS-DR14) quasar catalog. We performed a careful and homogeneous analysis of the SDSS spectra of these sources, to estimate the continuum and line properties of several emission lines such as H$α$, H$β$, H$γ$, Mg \textsc{ii}, C \textsc{iii]}, C \textsc{iv} and Ly$α$. From the derived emission line parameters, we estimated single-epoch virial black hole masses ($M_{\mathrm{BH}}$) for the sample using H$β$, Mg \textsc{ii} and C \textsc{iv} emission lines. The sample covers a wide range in bolometric luminosity ($\log L_{\mathrm{bol}}$; erg s$^{-1}$) between 44.4 and 47.3 and $\log M_{\mathrm{BH}}$ between 7.1 and 9.9 $M_{\odot}$. Using the ratio of $L_{\mathrm{bol}}$ to the Eddington luminosity as a measure of the accretion rate, the logarithm of the accretion rate is found to be in the range between $-$2.06 and 0.43. We performed several correlation analyses between different emission line parameters and found them to match with that known earlier using smaller samples. We noticed that strong Fe \textsc{ii} sources with large Balmer line width, and highly accreting sources with large $M_{\mathrm{BH}}$ are rare in our sample. We make available online an extended and complete catalog that contains various spectral properties of 526,265 quasars derived in this work along with other properties culled from the SDSS-DR14 quasar catalog.

description: This study was carried out to identify the benefits, adverse effects, social acceptance and a long term impacts of industrial wastewater reuse in the Tejgaon metropolitan area of Dhaka city. Questionnaire surveys were conducted in the exposed and control sites to collect data on the farmers’ perception and responses regarding agricultural, economic, social and environmental health issues. The most important benefits of wastewater reuse have been found as the availability of wastewater over all seasons and economic return from reduced chemical fertilizer requirement in vegetable field. The potential risks of wastewater reuse have been found as the increased insect attacks, diseases and excessive weed problem. Farmer mentioned that long term exposure of this water stimulates crop growth rapidly but it reduces grain production dramatically. Sometimes excess wastewater used for irrigation or short-term water logging in the area eventually leads to crop damage. Interviews with the key factors indicate that a long term institutional arrangement for sustainable reuse of wastewater is not beneficial in the region.

description: We consider a parabolic PDE with Dirichlet boundary condition and monotone operator $A$ with non-standard growth controlled by an $N$-function depending on time and spatial variable. We do not assume continuity in time for the $N$-function. Using an additional regularization effect coming from the equation, we establish the existence of weak solutions and in the particular case of isotropic $N$-function, we also prove their uniqueness. This general result applies to equations studied in the literature like $p(t,x)$-Laplacian and double-phase problems.

description: We explore the relevance of color superconductivity inside a possible quark matter core for the bulk properties of neutron stars. For the quark phase we use an Nambu--Jona-Lasinio (NJL) type model, extended to include diquark condensates. For the hadronic phase, a microscopic many-body model is adopted, with and without strangeness content. In our calculations, a sharp boundary is assumed between the hadronic and the quark phases. For NJL model parameters fitted to vacuum properties we find that no star with a pure quark core does exist. Nevertheless the presence of color superconducting phases can lower the neutron star maximum mass substantially. In some cases, the transition to quark matter occurs only if color superconductivity is present. Once the quark phase is introduced, the value of the maximum mass stays in any case below the value of two solar masses.

description: BackgroundHospital wastewater systems have been identified as reservoirs for antibiotic-resistant bacteria, with biofilms harbouring extended-spectrum β-lactamase (ESBL)-producing micro-organisms posing significant infection risk.AimTo study the antimicrobial susceptibility and biofilm control of ESBL-producing bacteria from wastewater pipes from a tertiary care teaching hospital in Ireland, which had experienced endemic infection outbreaks caused by ESBL-producing bacteria.MethodsFollowing isolation of ESBL producers on selective agar, antibiotic susceptibility profiles were determined for a number of antibiotics assessed for their ability to form biofilms. Biofilm eradication studies using the commercially available disinfectants bleach, Optizan™, Virkon™ and Clinell™ were performed on selected isolates.FindingsESBL-producing bacteria (N = 39 isolates) showed a high degree of resistance to β-lactams. Biofilm-forming ability ranged from non-adherent to strongly adherent and appeared to be source dependent, suggesting that the characteristics of the pipe environment played an important role in biofilm formation. All disinfectants showed effective biofilm eradication under suggested working conditions. Effectiveness was significantly reduced following reductions in concentration and contact time, with only Clinell™ showing significant biofilm reduction against all isolates at all concentrations and contact times tested. Of the chlorine-based formulations, Optizan™ frequently outperformed bleach at lower concentrations and treatment times. Biofilm eradication was strain dependent, with varying disinfectant response profiles observed from biofilms from different Stenotrophomonas maltophilia isolates.ConclusionsThis study highlights the high degree of ESBL-producing bacteria recovery from patient-facing hospital wastewater apparatus. Their ability to form resident biofilms and act as potential reservoirs of infection emphasizes the need for rigorous and effective infection control practices.
