description: Ziel unseres Projektes ist die statistische Analyse der bisher wenig erforschten asymmetrischen inkrementellen Blechumformung (AIBU). Ein elementares Problem hierbei ist die Quanti zierung der Qualität eines gefertigten Bauteils. Da der AIBU-Prozess ein inkrementeller Prozess ist, spielt die Qualität der gesamten dreidimensionalen Geometrie des Fertigteils eine Rolle. Nur wenn sie gänzlich quanti ziert werden kann, ist eine Untersuchung der Prozessdynamik möglich. Die dreidimensionale Vermessung des Fertigteils ist jedoch mit den herkömmlichen (taktilen) Messmethoden nur schwer möglich, daher stellen wir in diesem Diskussionspapier ein Verfahren zur Aufbereitung von optischen Messdaten vor, welches eine solche Analyse ermöglicht. Hierbei wird die Geometrie der Bauteile zunächst optisch komplett vermessen. Aufbauend auf diesen Messungen werden in einem mehrstu figen Ansatz die Messdaten mittels statistischer Methoden aufbereitet, um Artefakte heraus zu filtern, Ober- und Unterseiten zu trennen und schließlich auch die Wandstärken zu bestimmen. Kennt man die exakte Geometrie des Fertigteils und dessen Wandstärke über die gesamte Oberfläche, können hieraus leicht Qualitätskennzahlen errechnet werden. In Kapitel 2 werden zunächst die prozesstechnischen Grundlagen der AIBU und deren Prozessparameter und Einflussfaktoren eingeführt. In Kapitel 3 wird das in diesem Papier verwendete Experiment und die Messmethodik erklärt. Das Kapitel 4 befasst sich dann detailliert mit den einzelnen Schritten der Messdatenaufbereitung. Das letzte Kapitel diskutiert die Reproduzierbarkeit und Verlässlichkeit der vorgestellten Methode.

description: We discuss a 1+1 dimensional generalization of the Sachdev-Ye-Kitaev model. The model contains $N$ Majorana fermions at each lattice site with a nearest-neighbour hopping term. The SYK random interaction is restricted to low momentum fermions of definite chirality within each lattice site. This gives rise to an ordinary 1+1 field theory above some energy scale and a low energy SYK-like behavior. We exhibit a class of low-pass filters which give rise to a rich variety of hyperscaling behaviour in the IR. We also discuss another set of generalizations which describes probing an SYK system with an external fermion, together with the new scaling behavior they exhibit in the IR.

description: Localization estimates for GW150914, the first binary black hole detected by the LIGO instruments, were shared with partner facilities for electromagnetic follow-up. While the source was a compact binary coalescence (CBC), it was first identified by algorithms that search for unmodeled signals, which produced the skymaps that directed electromagnetic observations. Later on, CBC specific algorithms produced refined versions, which showed significant differences. In this paper we show that those differences were not accidental and that CBC and unmodeled skymaps for binary black holes will frequently be different; we thus provide a way to determine whether to observe electromagnetically as promptly as possible (following a gravitational-wave detection), or to wait until CBC skymaps become available, should they not be available in low latency. We also show that, unsurprisingly, CBC algorithms can yield much smaller searched areas.

description: Generating samples from the output distribution of a quantum circuit is a ubiquitous task used as a building block of many quantum algorithms. Here we show how to accomplish this task on a noisy quantum processor lacking full-blown error correction for a special class of quantum circuits dominated by Clifford gates. Our approach is based on Coherent Pauli Checks (CPCs) that detect errors in a Clifford circuit by verifying commutation rules between random Pauli-type check operators and the considered circuit. Our main contributions are as follows. First, we derive a simple formula for the probability that a Clifford circuit protected by CPCs contains a logical error. In the limit of a large number of checks, the logical error probability is shown to approach the value ${\approx}7εn/5$, where $n$ is the number of qubits and $ε$ is the depolarizing error rate. Our formula agrees nearly perfectly with the numerical simulation results. Second, we show that CPCs are well-suited for quantum processors with a limited qubit connectivity. For example, the difference between all-to-all and linear qubit connectivity is only a 3X increase in the number of CNOT gates required to implement CPCs. Third, we describe simplified one-sided CPCs which are well-suited for mitigating measurement errors in the single-shot settings. Finally, we report an experimental demonstration of CPCs with up to 10 logical qubits and more than 100 logical CNOT gates. Our experimental results show that CPCs provide a marked improvement in the logical error probability for the considered task of sampling the output distribution of quantum circuits.

Supersymmetric AdS$_{5}$ solutions of type IIB supergravity without D3 branes

description: We analyse the most general bosonic supersymmetric solutions of type IIB supergravity whose metrics are warped products of five-dimensional anti-de Sitter space (AdS$_5$) with a five-dimensional Riemannian manifold $M_{5}$, where the five-form flux vanishes, while all remaining fluxes are allowed to be non-vanishing consistent with SO(4,2) symmetry. This completes the program of classifying all supersymmetric solutions of ten and eleven-dimensional supergravity with an AdS$_5$ factor. We investigate the supersymmetry conditions in some special cases, and demonstrate how these are satisfied by a solution originally found in arXiv:1410.2650[hep-th], utilising the method of non-Abelian T-duality.

Racial Demographic Threat
Creators: name: Flores, Christian
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: How does racial demographic change affect polarization and support for democracy among white Americans? Past research has found that exposure to increasing ethnoracial diversity leads to conservative shifts in white Americans' views, though this finding has recently failed to replicate (Stewart and Willer 2021; Brown, Rucker, and Richeson 2021; McCarthy 2022). No research, however, has linked racial demographic exposure to party affect or support for democracy despite increasing affective polarization (Iyengar, Sood, and Lelkes 2012), the alignment of race with partisanship (Mason 2018; Westwood and Peterson), and the substantial antidemocratic actions supported by Republican elites in 2020. It is therefore unclear whether racial demographic information can spillover into beliefs about parties. In this pilot survey experiment, we expose white, eligible U.S. voters to a treatment group reading a report showing that whites are projected to become a minority in the near future (used also by Stewart and Willer 2021), a placebo group receiving an article about geographic mobility (following Craig and Richeson 2014), or a control receiving no article. The primary dependent variables are a scale of party social distance items, a scale of affective polarization (measured with a feeling thermometer) and party trust, a scale of antidemocratic attitudes, and a scale of trust in elections. The code file attached details the exact data cleaning and tests to be conducted. The sample will be 600 mTurk respondents (300 in treatment group, 150 in placebo, 150 in control). The Qualtrics survey is also attached. We will first test if treatment effects are significantly different between the placebo and control groups. If they are not, we will combine the two into one control group. If they are, we will proceed with them separately. There are 3 hypotheses: 1) no main effects, 2) treatment effects moderated by party ID, with Republicans more affectively polarized and expressing greater support for antidemocratic actions or beliefs, and 3) moderated mediation by group status threat (mediator) and party ID (moderator) -- Republicans will score higher in GST, which will mediate the treatment effects.
Perpendicular magnetic anisotropy of two-dimensional Rashba ferromagnets

description: We compute the magnetocrystalline anisotropy energy within two-dimensional Rashba models. For a ferromagnetic free-electron Rashba model, the magnetic anisotropy is exactly zero regardless of the strength of the Rashba coupling, unless only the lowest band is occupied. For this latter case, the model predicts in-plane anisotropy. For a more realistic Rashba model with finite band width, the magnetic anisotropy evolves from in-plane to perpendicular and back to in-plane as bands are progressively filled. This evolution agrees with first-principles calculations on the interfacial anisotropy, suggesting that the Rashba model captures energetics leading to anisotropy originating from the interface provided that the model takes account of the finite Brillouin zone. The results show that the electron density modulation by doping or an external voltage is more important for voltage-controlled magnetic anisotropy than the modulation of the Rashba parameter.

description: Rapid cooling of liquids below a certain temperature range can result in a transition to glassy states. The traditional understanding of glasses includes their thermodynamic metastability with respect to crystals. However, here we present specific examples of interactions that eliminate the possibilities of crystalline and quasicrystalline phases, while creating mechanically stable amorphous glasses down to absolute zero temperature. We show that this can be accomplished by introducing a new ideal state of matter called a "perfect glass." A perfect glass represents a soft-interaction analog of the maximally random jammed (MRJ) packings of hard particles. These latter states can be regarded as the epitome of a glass since they are out of equilibrium, maximally disordered, hyperuniform, mechanically rigid with infinite bulk and shear moduli, and can never crystallize due to configuration-space trapping. Our model perfect glass utilizes two-, three-, and four-body soft interactions while simultaneously retaining the salient attributes of the MRJ state. These models constitute a theoretical proof of concept for perfect glasses and broaden our fundamental understanding of glass physics. A novel feature of equilibrium systems of identical particles interacting with the perfect-glass potential at positive temperature is that they have a non-relativistic speed of sound that is infinite.
A closure operator on the subgroup lattice of $\mathrm{GL}(n,q)$ and $\mathrm{PGL}(n,q)$ in relation to the zeros of the Möbius function

description: Let $\mathbb{F}_q$ be the finite field with $q$ elements and consider the $n$-dimensional $\mathbb{F}_q$-vector space $V=\mathbb{F}_q^n\,$. In this paper we define a closure operator on the subgroup lattice of the group $G = \mathrm{PGL}(V)$. Let $μ$ denote the Möbius function of this lattice. The aim is to use this closure operator to characterize subgroups $H$ of $G$ for which $μ(H,G)\neq 0$. Moreover, we establish a polynomial bound on the number $c(m)$ of closed subgroups $H$ of index $m$ in $G$ for which the lattice of $H$-invariant subspaces of $V$ is isomorphic to a product of chains. This bound depends only on $m$ and not on the choice of $n$ and $q$. It is achieved by considering a similar closure operator for the subgroup lattice of $\mathrm{GL}(V)$ and the same results proven for this group.

description: Phase II dose finding studies in clinical drug development are typically conducted to adequately characterize the dose response relationship of a new drug. An important decision is then on the choice of a suitable dose response function to support dose selection for the subsequent Phase III studies. In this paper we compare different approaches for model selection and model averaging using mathematical properties as well as simulations. Accordingly, we review and illustrate asymptotic properties of model selection criteria and investigate their behavior when changing the sample size but keeping the effect size constant. In a large scale simulation study we investigate how the various approaches perform in realistically chosen settings. Finally, the different methods are illustrated with a recently conducted Phase II dosefinding study in patients with chronic obstructive pulmonary disease.

description: Learning from data has led to paradigm shifts in a multitude of disciplines, including web, text, and image search, speech recognition, as well as bioinformatics. Can machine learning enable similar breakthroughs in understanding quantum many-body systems? Here we develop an efficient deep learning approach that enables spatially and chemically resolved insights into quantum-mechanical observables of molecular systems. We unify concepts from many-body Hamiltonians with purpose-designed deep tensor neural networks (DTNN), which leads to size-extensive and uniformly accurate (1 kcal/mol) predictions in compositional and configurational chemical space for molecules of intermediate size. As an example of chemical relevance, the DTNN model reveals a classification of aromatic rings with respect to their stability -- a useful property that is not contained as such in the training dataset. Further applications of DTNN for predicting atomic energies and local chemical potentials in molecules, reliable isomer energies, and molecules with peculiar electronic structure demonstrate the high potential of machine learning for revealing novel insights into complex quantum-chemical systems.
Semiclassical Dynamics of Hawking Radiation

description: We consider gravity in 3+1 spacetime dimensions coupled to $N$ scalar matter fields in a semiclassical limit where $N\to\infty$. The dynamical evolution of a black hole including the back-reaction of the Hawking radiation on the metric is formulated as an initial value problem. The quantum stress energy tensor is evaluated using a point splitting regularization along spacelike geodesics. To account for the quantum entanglement of the matter fields, they are treated as a set of bilocal collective fields defined on spacelike hypersurfaces. The resulting semiclassical field equations include terms up to fourth order in derivatives that can be treated in a perturbative $\hbar$ expansion. The formulation we arrive at should be amenable to numerical simulation of time dependent semiclassical spacetime.

description: Il recupero di uno sguardo complesso sulle capacità conoscitive, sociali e corporee umane e sul rapporto col mondo, ha indotto il mondo della ricerca degli ultimi decenni ad avviare riflessioni e cambiamenti metodologici importanti. Le scienze esatte hanno ormai ridisegnato i loro criteri di scientificità, superando la frattura cartesiana mente-corpo con un pensiero sistemico del mondo. Alcune filosofie, attraverso il recupero del simbolo, delle narrazioni e di un’etica restauratrice di senso, attente all’interezza della dimensione umana, stanno camminando parallelamente alle scienze verso una visione sincretica dell’esistenza, di una conoscibilità incarnata e di un agire responsabile. Le sfide planetarie che le crisi socio- politiche ed ecologiche richiedono, impongono l’adozione di un pensiero ecologizzante che faccia emergere la pluralità dei punti di vista degli osservatori nelle scienze e la complessità degli aspetti e delle relazioni fra gli oggetti e i loro contesti, al fine di sviluppare un pensiero capace di confrontarsi con le urgenti problematiche evocate dall’Agenda Onu 2030.

The recovery of a complex view of human cognitive, social and bodily capacities and of the relationship with the world has led the world of research in recent decades to initiate important reflections and methodological changes. The exact sciences have now redesigned their scientific criteria, overcoming the Cartesian body fracture with a systemic thought of the world. Some philosophies, through the recovery of the symbol, the narratives and a restorative ethic of sense attentive to the entirety of the human dimension, they are walking parallel to the sciences towards a syncretic vision of existence, embodied knowability and responsible action. The global challenges that socio-political and ecological crises require, require the adoption of an ecological thinking that brings out the plurality of viewpoints of observers in the sciences and the complexity of the aspects and relationships between objects and their contexts, to in order to develop a thinking capable of dealing with the urgent problems evoked by the UN Agenda 2030.

Creators: name: Parrott, William George
Publisher: name: University of Glasgow
Year: 2022

description: This thesis presents the results of lattice Quantum Chromodynamics (QCD) calculations of hadronic matrix elements for pseudoscalar to pseudoscalar semileptonic decays involving c → s and b → s weak interaction transitions. We calculate scalar, vector and tensor form factors, and use them to test the Standard Model. Most prominently, we use D → Klv form factors, calculated on the lattice in the Highly Improved Staggered Quark formalism, to calculate a much more precise determination of the Cabbibo-Kobayashi-Maskawa (CKM) matrix element |Vcs|, allowing for more stringent tests of CKM unitarity. We also calculate branching fractions and other experimentally measurable quantities for the rare B → Kll decay, finding significant tension with experiment in this one-loop level process, which is sensitive to physics beyond the Standard Model.

This kind of field is characterized as not coupling directly to gravity; however, it is connected to the underlying matter content of the universe model. As is known, stealth fields do not back-react on the space-time; however, their mimicry skills show how this field and its self-interaction potential determines the cosmic evolution. We show the study of the simplest model that can be developed with the stealth field.

description: Parametric instabilities in interacting systems can lead to the appearance of new structures or patterns. In quantum gases, two-body interactions are responsible for a variety of instabilities that depend on the characteristics of both trapping and interactions. We report on the Floquet engineering of such instabilities, on a Bose-Einstein condensate held in a time-modulated optical lattice. The modulation triggers a destabilization of the condensate into a state exhibiting a density modulation with a new spatial periodicity. This new crystal-like order directly depends on the modulation parameters: the interplay between the Floquet spectrum and interactions generates narrow and adjustable instability regions, leading to the growth, from quantum or thermal fluctuations, of modes with a density modulation non commensurate with the lattice spacing. This study demonstrates the production of metastable exotic states of matter through Floquet engineering, and paves the way for further studies of dissipation in the resulting phase, and of similar phenomena in other geometries.

description: Network models are an essential block of modern networks. For example, they are widely used in network planning and optimization. However, as networks increase in scale and complexity, some models present limitations, such as the assumption of Markovian traffic in queuing theory models, or the high computational cost of network simulators. Recent advances in machine learning, such as Graph Neural Networks (GNN), are enabling a new generation of network models that are data-driven and can learn complex non-linear behaviors. In this paper, we present RouteNet-Fermi, a custom GNN model that shares the same goals as Queuing Theory, while being considerably more accurate in the presence of realistic traffic models. The proposed model predicts accurately the delay, jitter, and packet loss of a network. We have tested RouteNet-Fermi in networks of increasing size (up to 300 nodes), including samples with mixed traffic profiles -- e.g., with complex non-Markovian models -- and arbitrary routing and queue scheduling configurations. Our experimental results show that RouteNet-Fermi achieves similar accuracy as computationally-expensive packet-level simulators and scales accurately to larger networks. Our model produces delay estimates with a mean relative error of 6.24% when applied to a test dataset of 1,000 samples, including network topologies one order of magnitude larger than those seen during training. Finally, we have also evaluated RouteNet-Fermi with measurements from a physical testbed and packet traces from a real-life network.

description: Background: Globally adolescents are facing a range of sexual and reproductive health problems like unwanted pregnancy, unsafe abortion, STI including HIV. In addition, uptake of reproductive health services among adolescents remains low. Several factors are implicated for poor uptake of contraceptive methods among adolescent girls. However, adolescents' mother knowledge and attitude towards contraceptive methods on adolescent contraceptive utilization has not been adequately studied. Objective: To assess the prevalence of contraceptive use and associated factors among unmarried female adolescents. METHODS: A community based cross-sectional design with both quantitative and qualitative methods was conducted in Butajira South Central Ethiopia with a sample size of 491 unmarried female adolescent and their mothers. A multi stage sampling technique was used. Interviewer administered pre-tested structured questionnaire and interviewer topic guide was used to collect data for quantitative and qualitative respectively. The data was entered into Epidata and exported to STATA for analysis. The quantitative data analysis includes descriptive, bivariate and multivariate logistic regression analysis. Content analysis was use to analyze the qualitative data. Result: A total of 491 unmarried female adolescent & their mothers were approached of which 450 gave consent to participate in the study giving a response rate of 90.4%. The prevalence of contraceptive use among sexually active adolescent was 43(15.2%). A unit increase in adolescents' mothers knowledge score on contraceptive methods is associated with an increase in the odds of ever use of contraceptives among adolescent by 1.32 [AOR=1.32: (95%CI: 1.121.46)]. Furthermore ever use of contraceptive was found to be significantly associated with adolescents age [AOR=3.8 (95% CI: 1.33, 10.8)] and adolescents knowledge on contraceptive [AOR=1.23 (95%CI: 1.12-1.47)]. Our qualitative findings showed that majority of adolescents' mother do not advise use of contraceptives by their adolescent girls. Conclusion and Recommendation: Prevalence of contraceptive utilization among unmarried sexually active adolescent in BHDSS was low and maternal knowledge of modern contraceptive was found to be significantly associated with adolescent's contraceptive use. Therefore Policy makers and programmers should strengthen different programs to improve contraceptive utilizationamongadoelscents.

description: Virtual reality (VR) provides students with a platform to train in a 3D environment where their lab experiments can be replicated. By performing repetitive training, trainees can learn better in the Virtual Environment along with the benefits of the cost-effectiveness. The study focuses on two research questions: 1) Are there differences in the performance and errors committed by subjects in gamified vs. non-gamified educational labs? 2) Does the attitude of students matter in the gamified and non-gamified environment? This study examines the difference between gamified and non-gamified training environments' effectiveness in training performance and motivation in the VR training. During this study, the participants were provided with one of the two platforms –gamified and non-gamified and were asked to perform a micro-pipette experiment, where the users used a micropipette to transfer liquid from one container to another. The gamified environment has the visual elements for providing positive feedback to the users, and the non-gamified environment does not have these elements. During the experiment, the participants’ performance metrics like damage caused to the pipette and time taken to complete the experiment were captured. After the experiment, the participants were asked to answer a questionnaire related to the pipette usage, and then self-report their motivation during the experiment in the VR training. Based on the collected data, it was found that while the participants did seem more motivated in doing the gamified experiment, there were no differences between the performance in the gamified experiment and the non-gamified experiment. The participants were however more enthusiastic about the gamified experiment and were even able to provide suggestions to add more game elements. Suggestions for further research and more information on their feedback is also provided.

description: The main objective of this thesis is to improve the usefulness of spatial machine learning for the spatial sciences and to allow its unused potential to be exploited. To achieve this objective, this thesis addresses several important but distinct challenges which spatial machine learning is facing. These are the modeling of spatial autocorrelation and spatial heterogeneity, the selection of an appropriate model for a given spatial problem, and the understanding of complex spatial machine learning models.

description: Scalable quantum algorithms for the simulation of quantum many-body systems in thermal equilibrium are important for predicting properties of quantum matter at finite temperatures. Here we describe and benchmark a quantum computing version of the minimally entangled typical thermal states (METTS) algorithm for which we adopt an adaptive variational approach to perform the required quantum imaginary time evolution. The algorithm, which we name AVQMETTS, dynamically generates compact and problem-specific quantum circuits, which are suitable for noisy intermediate-scale quantum (NISQ) hardware. We benchmark AVQMETTS on statevector simulators and perform thermal energy calculations of integrable and nonintegrable quantum spin models in one and two dimensions and demonstrate an approximately linear system-size scaling of the circuit complexity. We further map out the finite-temperature phase transition line of the two-dimensional transverse field Ising model. Finally, we study the impact of noise on AVQMETTS calculations using a phenomenological noise model.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 1991

description: A comparative intervention study was conducted on 102 Community Health Agents (CRAs) in two Districts of Illubabor Administrative Region, south-western Ethiopia. The objective of the study was to look into the effect of health sector support, particularly of a refresher course and regular supervision, on the health service activities of CRAs. A total of 102 CRAs who were performing at least one activity specified in their job description were divided into two groups and designated by the lottery method as either intervention or control group. Baseline input to enhance community involvement was provided to both groups; a refresher course and monthly regular supervision were provided to the intervention group only. Both groups were followed for six consecutive months to collect data on 13 health service activities separately and as a composite, which represented the functional status of the CRA. The findings indicated that 60.7% of CRAs were initially performing at least one health service activity. A group x time analysis revealed that the composite functional score and most of the 13 activities increased after time o (TO) for CRAs in the intervention group but remained stable or declined in the control group. The mean composite score for intervention CRAs increased from 13.08 at time 0 (TO) to 19 . 26 at time 6 (T6); whereas for vii control CRAs it declined from 12.17 at TO to 9.58 at T6. The difference was attributed to the increase in health sector support, which in turn also helped to maintain community support.

description: ALPS II is a light shining through a wall style experiment that will use the principle of resonant enhancement to boost the conversion and reconversion probabilities of photons to relativistic WISPs. This will require the use of long baseline low-loss optical cavities. Very high power build up factors in the cavities must be achieved in order to reach the design sensitivity of ALPS II. This necessitates a number of different sophisticated optical and control systems to maintain the resonance and ensure maximal coupling between the laser and the cavity. In this paper we report on the results of the characterization of these optical systems with a 20 m cavity and discuss the results in the context of ALPS II.

description: Introduction:- The postnatal period starts an hour after the delivery of the placenta and includes the following six weeks. The postnatal period covers a critical transitional time for a woman, her newborn and her family on a physiological, emotional and social level. More than two third of maternal and new born deaths occur during the postnatal period and many of them develop disabilities The immediate cause of maternal deaths is the absence, inadequacy or underutilization of the health care system. In Ethiopia Maternal and Neonatal mortality still high and has received significant attention from the government. Routine essential postnatal care can help to reduce mortality and morbidity among mothers and their babies. Postnatal care program is one of the weakest programs among all reproductive heath programs of the country, but there is no sufficient research on how to improve the gap for low health service postnatal care utilization. The purpose of this study is to asses factors influencing utilization of health services for postnatal care during the first six weeks. PDF Creator - PDF4Free v2.0 http://www.pdf4free.com vii Methods: - A cross sectional study was conducted from date January to date February 2008. Study subjects were mothers who lived in Gondar urban town for two years and above, and six weeks completed to one year after delivery who were identified by house to house registration from randomly selected twelve centers in Gondar town. Data were collected using structured questionnaire containing variable related to sociodemographic, obstetric characteristics, perception of women about the risk of postnatal period, their belief in having postnatal care and knowledge when to start postnatal care. Result:-Out of five hundred sixty participants, 409(73%) health institution and 151 (27%) homes delivered 28.6%perceived the risk of postnatal period, 81.1% belief on having postnatal care but 81.3% have knowledge on starting time after 45 days 0.5% said immediately where others no need of postnatal care. Out of seventy three percent health institution deliveries 88.3% mothers did not provide an appointment or information to have health service postnatal care. 38.2% utilized health service during post natal period .Main reason for initiation 28.5% maternal and 15% child health problems, 4.2% due to having an appointment the rest 52.3% for vaccination. Conclusion: - Health service postnatal care for mothers and babies was very weak in health institution.
