description: We construct a new family of $\text{AdS}_2\times S^2\times S^2$ solutions to Type IIA supergravity with 4 supercharges acting with non-Abelian T-duality on the recent class constructed in arXiv:2107.12277. We focus on a particular solution in this class asymptoting locally to an $\text{AdS}_5$ Gaiotto-Maldacena geometry. This solution allows for a line defect interpretation within the 4d $\mathcal{N}=2$ SCFT dual to this geometry, that we study in detail. We show that the defect branes, consisting on a non-trivial intersection of D2-D4-NS5-F1 branes, can be interpreted as baryon vertices within the 4d $\mathcal{N}=2$ SCFT, whose backreaction gives rise to the $\text{AdS}_2$ solution. We construct the explicit quiver quantum mechanics that flows in the IR to the dual SCQM, and show that it can be embedded within the quiver CFT associated to the $\text{AdS}_5$ solution. The quiver quantum mechanics arises from a brane box set-up of D2-branes stretched between perpendicular NS5-branes, that we construct from the $\text{AdS}_2$ solution. We provide non-trivial checks of our proposed duality. Our construction provides one further example of the successful applications of non-Abelian T-duality to holography, in this case in providing a very non-trivial connection between $\text{AdS}_2$ solutions, line defects and brane boxes.

description: Online public discussion has the potential to mitigate the disturbing trend of social polarization. However, as a result of the rise of online toxic behaviors, such beneﬁts have been severely hindered. Based on the social judgment theory, this study examined the role of worldviews in predicting toxic behaviors. This work used toxic conversations on the Reddit changemyview subreddit and analyzed 45 million comments made by 9,546 users across all Reddit communities between 2015 and 2019. This paper found that, combining worldviews with basic text representation features (Word2Vec) on a simple logistic regression led the framework to outperform the state-of-the-art obtained on sophisticated deep learning models. The existence of toxic conversations could therefore be explained by worldviews. This work informs the design of toxicity detection systems to take into account not only the information extracted from current conversations, but also the worldviews shown in the utterances of users over the years.

title: The integrated stress response kinase general control non-derepressible 2 (GCN2) is a novel prognostic biomarker and therapeutic target in malignant pleural mesothelioma
titleType: Other
Creators: name: Gold, Lyssa Talia
Publisher: name: University of Dundee
Year: 2023

description: Malignant pleural mesothelioma (MPM) is a cancer of the mesothelial cells of the pleural cavity, with a five-year survival rate of five percent and extremely limited treatment options with poor response rates. Previous work identified the transcription factor C/EBP homologous protein (CHOP) as a prognostic biomarker in MPM. CHOP levels are also associated with the amino acid response (AAR) arm of the integrated stress response (ISR), mediated by nutrient stress sensing kinase general control non-derepressible 2 (GCN2). GCN2 activity is hijacked in multiple cancers to overcome nutrient starvation associated with tumorigenesis, and both inhibiting and activating compounds have shown promising results as potential new therapeutics. This work immunohistochemically stained MPM tumour samples for GCN2 and determined whether levels were associated with patient prognosis. GCN2 levels were associated with worse patient prognoses and was also a predictive factor for one-year outcomes. GCN2 may therefore prove a useful staining target to determine prognosis in MPM patients. Additionally, the correlation between high GCN2 levels and worse patient prognoses suggests that GCN2 levels are associated with more aggressive cancer and identifies a potential weakness in MPM tumours that could be exploited therapeutically.

description: Magnetic reconnection is an important source of energetic particles in systems ranging from astrophysics to the laboratory. The large separation of spatiotemporal scales involved makes it critical to determine the minimum physical model containing the necessary physics for modeling particle acceleration. By resolving the energy gain from ideal and nonideal magnetohydrodynamic electric fields self-consistently in kinetic particle-in-cell simulations of reconnection, we conclusively show the dominant role of the nonideal field for the early stage of energization known as injection. The importance of the nonideal field increases with magnetization, guide field, and in three-dimensions, indicating its general importance for reconnection in natural astrophysical systems. We obtain the statistical properties of the injection process from the simulations, paving the way for the development of extended MHD models capable of accurately modeling particle acceleration in large-scale systems. The novel analysis method developed in this study can be applied broadly to give new insight into a wide range of processes in plasma physics.

description: The strong coupling constants of the $π$ and $K$ mesons with negative parity octet baryons are estimated within the light cone QCD sum rules. It is observed that all strong coupling constants, similar to the case for the positive parity baryons, can be described in terms of three invariant functions, where two of them correspond to the well known $F$ and $D$ couplings in the $SU(3)_f$ symmetry, and the third function describes the $SU(3)_f$ symmetry violating effects. We compare our predictions on the strong coupling constants of pseudoscalar mesons of negative parity baryons with those corresponding to the strong coupling constants for the positive parity baryons.

description: Non-contact vital sign monitoring has many advantages over conventional methods in being comfortable, unobtrusive and without any risk of spreading infection. The use of millimeter-wave (mmWave) radars is one of the most promising approaches that enable contact-less monitoring of vital signs. Novel low-power implementations of this technology promise to enable vital sign sensing in embedded, battery-operated devices. The nature of these new low-power sensors exacerbates the challenges of accurate and robust vital sign monitoring and especially the problem of heart-rate tracking. This work focuses on the investigation and characterization of three Frequency Modulated Continuous Wave (FMCW) low-power radars with different carrier frequencies of 24 GHz, 60 GHz and 120 GHz. The evaluation platforms were first tested on phantom models that emulated human bodies to accurately evaluate the baseline noise, error in range estimation, and error in displacement estimation. Additionally, the systems were also used to collect data from three human subjects to gauge the feasibility of identifying heartbeat peaks and breathing peaks with simple and lightweight algorithms that could potentially run in low-power embedded processors. The investigation revealed that the 24 GHz radar has the highest baseline noise level, 0.04mm at 0° angle of incidence, and an error in range estimation of 3.45 +- 1.88 cm at a distance of 60 cm. At the same distance, the 60 GHz and the 120 GHz radar system shows the least noise level, 0.0lmm at 0° angle of incidence, and error in range estimation 0.64 +- 0.01 cm and 0.04 +- 0.0 cm respectively. Additionally, tests on humans showed that all three radar systems were able to identify heart and breathing activity but the 120 GHz radar system outperformed the other two.
Supporting the Progress of Math Intervention: Effects of An Instruction- assessment System on Teacher’s Motivation and Practices

Subjects: subject: teacher
subject: math intervention

description: This study examined the effect of preschoolers’ math intervention on teachers’ instructions and motivation for teaching within the context of an instruction-assessment system called Getting on Track (GoT). Four YMCA teachers participated in this study and completed the questionnaire including the following motivational aspects: self-efficacy, interest, effort, and confidence. They were also asked to evaluate a variety of resources and tasks related to the GoT assessment. Data from the Teacher Comfort Survey and the Coach Interview Report in Indiana collected by the GoT researchers in 2017-18 served as complementary information to further explain the findings of this study. The results showed that teachers paid more attention to children’s math learning process and differentiated instructions to meet their needs. Although most teachers demonstrated increased self-efficacy and enjoyment, their use of the GoT was not found to be effective in increasing teacher motivation. Possible reasons for this included the remaining barriers and difficulties that had not yet been addressed in the coaching sessions.
Dynamics of a coupled spin vortex pair in dipolar spinor Bose-Einstein condensates

description: The collisional and magnetic field quench dynamics of a coupled spin-vortex pair in dipolar spinor Bose-Einstein condensates in a double well potential are numerically investigated in the mean field theory. Upon a sudden release of the potential barrier the two layers of condensates collide with each other in the trap center with the chirality of the vortex pair exchanged after each collision, showing the typical signature of in-phase collision for the parallel spin vortex phase, and out-of-phase collision for the antiparallel phase. When quenching the transverse magnetic field, the vortex center in the single-layered condensate starts to make a helical motion with oval-shaped trajectories and the displacement of the center position is found to exhibit a damped simple harmonic oscillation with an intrinsic frequency and damping rate. The oscillation mode of the spin vortex pair may be tuned by the initial magnetic field and the height of the Gaussian barrier, e.g. the gyrotropic motions for parallel spin vortex pair are out of sync with each other in the two layers, while those for the antiparallel pair exhibit a double-helix-structure with the vortex centers moving opposite to each other with the same amplitude.

description: Although strange quarks are produced in $s\bar{s}$ pairs, the ratio of $Ω^{-}$ to ${\barΩ}^{+}$ is greater than one in heavy-ion collisions at lower RHIC energies. Thus the produced $Ω$ hyperons must carry net baryon quantum numbers from the colliding nuclei. We present results of $K$-$Ω$ correlations from AMPT model simulations of Au+Au collisions at $\sqrt{s_{NN}}$ = 14.6 GeV, to probe dynamics for baryon number transport to mid-rapidities at this beam energy. We use both the default and string-melting versions to illustrate how hadronization schemes of quark coalescence and string fragmentations could leave imprints on such correlations. Implications on the measurements of these correlations with the STAR experiment at RHIC will also be discussed.

description: Although temporal persistence, or permanence, is a well understood requirement for optimal biometric features, there is no general agreement on how to assess temporal persistence. We suggest that the best way to assess temporal persistence is to perform a test-retest study, and assess test-retest reliability. For ratio-scale features that are normally distributed, this is best done using the Intraclass Correlation Coefficient (ICC). For 10 distinct data sets (8 eye-movement related, and 2 gait related), we calculated the test-retest reliability ('Temporal persistence') of each feature, and compared biometric performance of high-ICC features to lower ICC features, and to the set of all features. We demonstrate that using a subset of only high-ICC features produced superior Rank-1-Identification Rate (Rank-1-IR) performance in 9 of 10 databases (p = 0.01, one-tailed). For Equal Error Rate (EER), using a subset of only high-ICC features produced superior performance in 8 of 10 databases (p = 0.055, one-tailed). In general, then, prescreening potential biometric features, and choosing only highly reliable features will yield better performance than lower ICC features or than the set of all features combined. We hypothesize that this would likely be the case for any biometric modality where the features can be expressed as quantitative values on an interval or ratio scale, assuming an adequate number of relatively independent features.

description: Filling out the dearth of detections between direct imaging and radial velocity surveys will test theories of planet formation and (sub)stellar binarity across the full range of semi-major axes, connecting formation of close to wide separation gas giants and substellar companions. Direct detection of close-in companions is notoriously difficult: coronagraphs and point spread function (PSF) subtraction techniques fail near the λ/D diffraction limit. We present a new faint companion detection pipeline called Argus which analyzes kernel phases, an interferometric observable analogous to closure phases from non-redundant aperture masking but utilizing the full unobscured telescope aperture. We demonstrate the pipeline, and the power of interferometry, by performing a companion search on the entire HST/NICMOS F110W and F170M image archive of 114 nearby brown dwarfs (observed in 7 different programs). We discover no new companions but recover and refine astrometry of 18 previous imaging companions (two with multiple epochs). We confirm two previous kernel-phase detections and do not recover a number of other candidates. We present contrast curves showing that our pipeline is able to detect companions down to flux ratios of ∼102 at half the classical diffraction limit. We then conduct a demographic study of our detections and detection limits using a Bayesian framework. When incorporating a limit on unresolved binaries (based on an RV survey) we find a companion frequency of 25% which, even with sensitivity to much tighter separation companions, is consistent with previous studies of substellar multiplicity. We find a slightly wider distribution (log-normal width of 0.7 dex) centered at a tighter separation (2.1 au) than previous studies with lower sensitivity to tight companions. We also find a steep mass ratio powerlaw index of 5.5-14 depending on the assumed field age of the sample (0.9-3.0 Gyr). We also present results of our current work applying this pipeline to HST/ACS observations of the young star-forming regions of Taurus and Upper Scorpius, searching for lower mass companions at tighter separations than previously accessible with classical PSF fitting techniques.

description: Any company's human resources department faces the challenge of predicting whether an applicant will search for a new job or stay with the company. In this paper, we discuss how machine learning (ML) is used to predict who will move to a new job. First, the data is pre-processed into a suitable format for ML models. To deal with categorical features, data encoding is applied and several MLA (ML Algorithms) are performed including Random Forest (RF), Logistic Regression (LR), Decision Tree (DT), and eXtreme Gradient Boosting (XGBoost). To improve the performance of ML models, the synthetic minority oversampling technique (SMOTE) is used to retain them. Models are assessed using decision support metrics such as precision, recall, F1-Score, and accuracy.

description: Effective non-Hermitian Hamiltonians are obtained to describe coherent perfect absorbing and lasing boundary conditions. PT -symmetry of the Hamiltonians enables to design configurations which perfectly absorb at multiple frequencies. Broadened and flat perfect absorption is predicted at the exceptional point of PT -symmetry breaking while, for a particular case, absorption is enhanced with the use of gain. The aforementioned phenomena are illustrated for acoustic scattering through Helmholtz resonators revealing how tailoring the non-Hermiticity of acoustic metamaterials leads to novel mechanisms for enhanced absorption.
Residual gauge symmetry in light-cone electromagnetism

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We analyze the residual gauge freedom in light-cone electromagnetism in four dimensions. The standard boundary conditions involved in the so-called $lc_2$ formalism, which contains only the two physical degrees of freedom, allow for a subset of residual gauge transformations. We relax the boundary conditions imposed on the fields in order to obtain all the residual gauge transformations. We compute the canonical generators for Poincaré and gauge transformations with these relaxed boundary conditions. This enables us to distinguish between the trivial (proper) and large (improper) gauge transformations in light-cone electromagnetism. We then employ the Newman-Penrose formalism to identify the incoming and outgoing radiation fields. We comment on the quadratic form structure of light-cone Hamiltonians, often encountered in $lc_2$ gauge theories.

description: We give an update on the ongoing effort of the RC$^\star$ collaboration to generate fully dynamical QCD+QED ensembles with C$^\star$ boundary conditions using the openQ$^\star$D code. The simulations were tuned to the U-symmetric point ($m_d = m_s$) with pions at $m_{π^{\pm}} \approx 400$ MeV. The splitting of the light mesons is used as one of three tuning observables and fixed to $m_{K^{0}} - m_{K^{\pm}} \approx 5$ MeV and $m_{K^{0}} - m_{K^{\pm}} \approx 25$ MeV on ensembles with renormalized electromagnetic coupling $α_{\text{R}} \approx α_{\text{phys}}$ and $α_R \approx 5.5α_{phys}$ respectively. The tuning of the three independent quark masses to the desired lines of constant physics is particularly challenging. We will define the chosen hadronic renormalization scheme, and we will present a tuning strategy based on a combination of mass reweighting and linear interpolation to explore the parameter space. We will comment on finite-volume effects comparing meson masses on two different volumes with $m_{π^{\pm}} L \approx 3.2$ and $m_{π^{\pm}} L \approx 5.1$. We will also provide some technical details on our updated strategy to calculate the sign of the fermionic Pfaffian, which arises in presence of C$^\star$ boundary conditions in place of the standard fermionic determinant. More technical details on the generation of the configurations can be found in J. Lücke's proceedings

Standing out or Fitting in, Business Pitch and Pivot: Institutional Isomorphism and Differentiation Strategy

Subjects: subject: Innovation, organizational theory, social network analysis

description: The game of “standing out” or “fitting in” is pervasive in the social world. A game faced by individuals and organizations alike, navigating between these two ends and finding a balance become important to the survival and prosperity of the social entity.While innovation emerges from “standing out” from the rest of the industry, such novelty could also alienate the company from the rest of the pack. On the other hand, fitting into the industry also prevents the company from capturing additional market share and becoming the industry leader. How do companies find this balance? In this paper, we investigate this central question through analyzing company description text from Crunchbase (early-stage companies) and annual 10-K’s (mature, public companies). There are three dimensions to this analysis. First, how do companies change their pitches overtime? Second, what drives and results from pivoting? Third, how do companies fit in with the rest of the industry they find themselves in – and how is this different between early-stage v.s. mature, public companies? We hypothesize that pitches become more professional overtime, and that early-stage companies are more likely to pivot and disrupt the industry because pivoting is beneficial.

description: Location Quotients (LQs) are widely used to assess industry concentration in specific regions relative to broader areas. However, their utility in predicting societal outcomes such as wealth, health, and education remains less explored. This study aims to examine the links between selected industry location quotients and economic determinants of household income and poverty rate in Florida. Other factors, such as healthcare and education, were also considered to quantify the macroeconomic impact of these industries in Florida. Additionally, healthcare and education factors are considered to gauge the overall macroeconomic impact of these industries. Employing a Structural Equation Model with a three-stage least squares regression approach, our analysis unveils nuanced effects: while certain sectors bolster economic outcomes, others 2 contribute to economic disparities. For instance, the Construction and Accommodation/Food Services sectors are found to influence local economies positively. Understanding these industry dynamics at the county level enables more informed local planning and long-term support strategies for communities.

description: The design and realization of a cryogenic rig for point-contact spectroscopy measurements in the needle-anvil configuration is presented. Thanks to the use of two piezoelectric nano-positioners, the tip can move along the vertical ($z$) and horizontal ($x$) direction and thus the rig is suitable to probe different regions of a sample \textit{in situ}. Moreover, it can also form double point-contacts on different facets of a single crystal for achieving, e.g., an interferometer configuration for phase-sensitive measurements. For the latter purpose, the sample holder can also host a Helmholtz coil for applying a small transverse magnetic field to the junction. A semi-rigid coaxial cable can be easily added for studying the behavior of Josephson junctions under microwave irradiation. The rig can be detached from the probe and thus used with different cryostats. The performance of this new probe has been tested in a Quantum Design PPMS system by conducting point-contact Andreev reflection measurements on Nb thin films over large areas as a function of temperature and magnetic field.

In contrast, selective upcycling of various plastics offers a promising solution for converting waste plastics into valuable products. This review provides a comprehensive overview of the recent advancements in innovative catalytic technologies, including thermocatalysis, electrocatalysis, and photocatalysis. Special emphasis is placed on elucidating the reaction mechanisms, activating designated chemical bonds for high selectivity, and elaborating the above techniques in terms of reaction conditions and products. Finally, the application prospects and future development trends in plastic catalysis are discussed, providing valuable insights for realizing a sustainable circular plastic economy.

description: We investigate the extent to which a two-level quantum system subjected to an external time-dependent drive can be characterized by supervised learning. We apply this approach to the case of bang-bang control and the estimation of the offset and the final distance to a given target state. For any control protocol, the goal is to find the mapping between the offset and the distance. This mapping is interpolated using a neural network. The estimate is global in the sense that no a priori knowledge is required on the relation to be determined. Different neural network algorithms are tested on a series of data sets. We show that the mapping can be reproduced with very high precision in the direct case when the offset is known, while obstacles appear in the indirect case starting from the distance to the target. We point out the limits of the estimation procedure with respect to the properties of the mapping to be interpolated. We discuss the physical relevance of the different results.

description: To succeed in a Big Data strategy, you have to arm yourself with a wide range of data skills and best practices. This strategy can result in an impressive asset that can streamline operational costs, reduce time to market, and enable the creation of new products. However, several Big Data challenges may take place in enterprises when it comes to moving initiatives of boardroom discussions to effective practices. From a broader perspective, we take on this paper two very important challenges, namely modeling, and management. The main context here is to highlight the importance of understanding data modeling and knowing how to process complex data while supporting the characteristics of each model.

description: We compare the heat release data of organic glasses with that of amorphous and glass like crystalline solids. Anomalous behavior was found in all these materials, which disagrees with the standard tunneling model. We can explain the most of the experimental observations within a phenomenological model, where we assume that for a part of tunneling systems the barrier heights are strongly reduced as a consequence of the local stress produced during the cooling process.
Standing out or Fitting in, Business Pitch and Pivot: Institutional Isomorphism and Differentiation Strategy
Creators: name: Zhao, Chuqing
Publisher: name: University of Chicago

Subjects: subject: innovation
subject: organizational theory
subject: social network analysis

description: The game of “standing out” or “fitting in” is pervasive in the social world. A game faced by individuals and organizations alike, navigating between these two ends and finding a balance become important to the survival and prosperity of the social entity. This reification is especially true for business organizations. While innovation emerges from “standing out” from the rest of the industry, such novelty could also alienate the company from the rest of the pack. On the other hand, fitting into the industry also prevents the company from capturing additional market share and becoming the industry leader. How do companies find this balance? Given the height of U.S. venture capital funding at the moment, at an all time high in 20 years mirroring the funding level of the dot-com boom in the 2000s, the question of standing out or fitting in becomes increasingly important to early-stage companies. To partake and benefit from the venture capital carnival, companies often pivot their products and business models to generate more value to attract investors. Though the startup and venture capital community disagree on the key value drivers of a company, there is consensus on the importance of pivots. What are patterns of pivots and companies that pivot, and do they stand out or fit in overtime with these pivots? In this paper, I investigate this central question through analyzing company description text from Crunchbase (early-stage companies) and annual 10-K’s (mature, public companies). There are three dimensions to this analysis. First, how do companies change their pitches overtime? Second, what drives and results from pivoting? Third, how do companies fit in with the rest of the industry they find themselves in – and how is this different between early-stage v.s. mature, public companies? We hypothesize that pitches become more professional overtime, and that early-stage companies are more likely to pivot and disrupt the industry because pivoting is beneficial.

description: Coupling a microscopic mechanical resonator to a nano-scale quantum system enables control of the mechanical resonator via the quantum system, and vice versa. The coupling is usually achieved through functionalization of the mechanical resonator but this results in additional mass and dissipation channels. An alternative is an intrinsic coupling based on strain. We employ here a monolithic semiconductor system. The nano-scale quantum system is a quantum dot; the mechanical resonator a microscopic trumpet which simultaneously optimizes the mechanical and photonic properties. The quantum dot transition is driven resonantly. Via the resonance fluorescence, we observe mechanical Brownian motion even at 4K, and demonstrate a coupling to mechanical modes of different types. We identify a mechanical mode with a cooperativity larger than one. We show analytically that the Heisenberg limit on displacement measurement can be reached with an embedded two-level system in the case of a transform-limited optical emitter with perfect photon detection. We argue that operation close to the Heisenberg limit is achievable with state-of-the-art quantum dot devices.

description: In this paper we consider the metric power-law $f(R)\sim R^n $-gravity model for the four-dimensional metric tensor depending on two coordinates. We obtain exact analytical vacuum solutions for different values of $ n $. These solutions contain both non-stationary configurations of the travelling wave type and stationary ones, in particular, depending on one radial variable.

Topological Phase Transition Coupled with Spin-Valley Physics in Ferroelectric Oxide Heterostructures

description: The possibility to engineer the coupling of spin and valley physics is explored in ferroelectric oxide heterostructures with eg electronic configuration. We show that the polar structural distortion induces the appearance of spin-valley coupled properties, at the same time being responsible for a topological transition from a quantum spin-Hall insulating phase to a trivial band insulator. The coupled spin-valley physics is affected by the topological band inversion in a non-trivial way; while the valley-dependent spin polarization of both conduction and valence bands is preserved, a change of the Berry curvature and of spin-valley selection rules is predicted, leading to different circular dichroic response as well as valley and spin Hall effects.

description: The Spanish National Bioinformatics Institute (INB) is the ELIXIR Node in Spain (ELIXIR-ES). The INB was founded in 2003 as a distributed network of nodes with a central coordination hub. Since its renewal process (2018 - 2020), the INB/ELIXIR-ES has increased the participant nodes to 19 research groups distributed across 13 institutions in Spain, and it has become the bioinformatics platform of Institute of Health Carlos III (ISCIII). The two main overarching objectives are: deepen its alignment with ELIXIR and its communities with a strong focus on human data related activities; and increasing its translational medicine ties with the Spanish National Health System (SNS).
Unfit Caretakers: Representations of Enslaved Women and Reproduction in British West Indies Medical Literature, 1764-1833
Creators: name: Keller, Elizabeth D.
Publisher: name: University of Chicago
Year: 2022
Subjects: subject: yaws, lockjaw, enslaved women, enslaved nurses, enslaved mothers, abolition, enslaved reproduction, British West Indies, Jamaica, Barbados, St. Kitts

description: In this paper I examine the representations of enslaved women in texts concerning the treatment and transmission of yaws and lockjaw in the British West Indies during the era of abolition. Using these two diseases as case studies I analyze why physicians, plantation owners, and other commentators constructed the enslaved woman as irresponsible, promiscuous, and incapable of caring for herself and others. These medical, political, and historical texts served to assert their authors as necessary experts in a subject and to justify their intervention in the reproductive and neonatal health of enslaved women. I also connect these representations to larger trends surrounding the institutionalization of maternal care, the treatment of women in general, and other common cultural stereotypes about African peoples.

description: Proton capture cross sections in the energy range of astrophysical interest for mass region 40-54 have been calculated in the Hauser-Feshbach formalism with reaction code TALYS1.6. The density dependent M3Y effective nucleon-nucleon interaction folded with target radial matter densities from relativistic mean field approach is used to obtain the semi-microscopic optical potential. A definite normalization of potential-well depths has been used over the entire mass region. The $(p,γ)$ rates of some reactions, important in the astrophysical scenario, are calculated using the potential in the relevant mass region.
