How big is the moral umbrella? : (an enquiry concerning moral scope)
Creators: name: Mountford, C. Perraton
Publisher: name: University of British Columbia
Year: 2009

description: The question What kinds of things are morally important in themselves? (People? All sentient creatures? Trees? All living things? Ecosystems? Mountains? Rivers? Pebbles? Old cans?) is pressing. Thanks to 'animal rights' activism, the abortion debate, environmentalism, and a sense that technology needs greater moral guidance, analytic philosophy now offers four broad answers: HUMANISM (all and only humans), SENTIENTISM (all creatures capable of 'affect'), VITALISM (all individual living organisms) , and ECOSOPHISM (all living individuals plus some natural 'systems' and, perhaps, certain nonliving natural entities). These answers are carefully developed and contain many persuasive elements. However, critical exploration of representative literature reveals that each answer is predicated on a distinct and different view of morality's purpose, and we are rationally free to reject any (or all) of those views. In consequence, debate stalls. Short of question-begging appeals to first principles, the positions fall back on touting their relative merits. The best we can say is that humanists extending consideration to all humans will face difficulty resisting sentientism, but even sentientism is not rationally incumbent. Once we look beyond life-forms to whom events can matter in some way, expansionist arguments clearly fail to speak to humanist (and sentientist) concerns. Because humanism (and, to a lesser extent, sentientism) is informed by longstanding tradition, a considerable burden of proof impedes expansionist ambitions. The expansionist programme requires finding common ground; ground which is not obviously in evidence. To conclude, I offer an explicitly tentative suggestion for beginning to resolve this impasse. All parties should agree that whatever else morality does (or does not) achieve, rational morality promotes human well-being. And it is abundantly clear that human well-being requires a healthy, sustainable environment. Thus, an instrumental, pragmatic, approach to framing moral requirements seems to offer grounds for moral expansion. But can this essentially anthropocentric view of morality and environmentalism be used to determine what kinds of things are morally important in themselves? Separating our reasoning about morality from situated moral reasoning per se, reveals reason to think the approach can and will support a vitalist, or even ecosophist, account of moral scope.

description: Intrinsic topological superconductors with p-wave pairing are rare in nature. Its underlying reason is due to the fact that it is usually difficult to change the relative strength between the singlet and triplet channels for the electron-electron interaction in material. Here we show that by considering superconductivity occurring on surfaces of topological insulators (TIs), the relative strength between the singlet and triplet channels can be changed by geometry and sizes of TIs. Specifically, we show that pairing of electrons at different locations on the surface of a topological insulator generally tends to favor the triplet pairing and can induce topological superconductivity by controlling the surface curvature and size of the topological insulator. We illustrate the effects in two configurations, thin film geometry and the spherical geometry with a sphere or a hemisphere, and find that topological superconductivity arises with the $p \pm ip$ pairing symmetry dominated in nanoscale size of the TI. As a consequence, vortices can spontaneously form on surfaces of topological insulators with roughness of appropriate curvature. These vortices support a Majorana zero mode inside each core and can be used as a platform to host Majorana zero modes without invoking real magnetic fields. Our theoretical discovery opens a new route to realize topological superconductivity in material.

description: We describe a recent experiment performed with rubidium atoms ($^{87}$Rb), aiming at studying the coherence properties of a two-dimensional gas of bosonic particles at low temperature. We have observed in particular a Berezinskii--Kosterlitz--Thouless (BKT) type crossover in the system, using a matter wave heterodyning technique. At low temperatures, the gas is quasi-coherent on the length scale set by the system size. As the temperature is increased, the loss of long-range coherence coincides with the onset of the proliferation of free vortices, in agreement with the microscopic BKT theory.

description: The practice of social distancing is imperative to curbing the spread of contagious diseases and has been globally adopted as a non-pharmaceutical prevention measure during the COVID-19 pandemic. This work proposes a novel framework named SD-Measure for detecting social distancing from video footages. The proposed framework leverages the Mask R-CNN deep neural network to detect people in a video frame. To consistently identify whether social distancing is practiced during the interaction between people, a centroid tracking algorithm is utilised to track the subjects over the course of the footage. With the aid of authentic algorithms for approximating the distance of people from the camera and between themselves, we determine whether the social distancing guidelines are being adhered to. The framework attained a high accuracy value in conjunction with a low false alarm rate when tested on Custom Video Footage Dataset (CVFD) and Custom Personal Images Dataset (CPID), where it manifested its effectiveness in determining whether social distancing guidelines were practiced.

description: Inventory Routing Problem (IRP) is a crucial challenge in supply chain management as it involves optimizing efficient route selection while considering the uncertainty of inventory demand planning. To solve IRPs, usually a two-stage approach is employed, where demand is predicted using machine learning techniques first, and then an optimization algorithm is used to minimize routing costs. Our experiment shows machine learning models fall short of achieving perfect accuracy because inventory levels are influenced by the dynamic business environment, which, in turn, affects the optimization problem in the next stage, resulting in sub-optimal decisions. In this paper, we formulate and propose a decision-focused learning-based approach to solving real-world IRPs. This approach directly integrates inventory prediction and routing optimization within an end-to-end system potentially ensuring a robust supply chain strategy.

description: We study the quantum limits in an optomechanical sensor based on a detuned high-finesse cavity with a movable mirror. We show that the radiation pressure exerted on the mirror by the light in the detuned cavity induces a modification of the mirror dynamics and makes the mirror motion sensitive to the signal. This leads to an amplification of the signal by the mirror dynamics, and to an improvement of the sensor sensitivity beyond the standard quantum limit, up to an ultimate quantum limit only related to the mechanical dissipation of the mirror. This improvement is somewhat similar to the one predicted in detuned signal-recycled gravitational-waves interferometers, and makes a high-finesse cavity a model system to test these quantum effects

description: Spinal immmobilizasyon, travma hastalarının acil yönetiminde önemli yer tutmaktadır. Günlük acil servis pratiğimizde spinal immobilizasyon, güncel travma klavuzlarının önerdiği, bizim de bu sebeple sık kullandığımız bir yönetim şekli. Ancak literatürde penetran travmalarda spinal immobilizasyonun yeri ile alakalı çok sayıda ve güçlü kanıt bulunmamakta. Bu sebeple klinisyenler penetran yaralanmalarda spinal immobilizasyon uygulama konusunda daha net bir kılavuz önerisine ihtiyaç duymaktadır. Yapılmış olan birçok çalışma göstermiştir ki; penetran yaralanmalarda spinal immobilizasyon amacıyla kullanılan servikal boyunluk ve travma tahtası uygulamaları, spinal hareket kısıtlılığını tam olarak sağlayamamakta ve buna ek olarak immobilizasyonun kar/zarar hesabınında ibreyi zarar tarafına doğru yönlendirebilmektedir1–5. Bu bahsi geçen çalışmalar ve başka birçok yazar, spinal immobilizasyona bağlı gelişen lokal bası yaralanmaları, artmış intrakraniyal basınç, yara yerinin maskelenmesi ve bu sebeple gözden kaçırılması, ve entübasyon gibi ciddi hayat kurtarıcı prosedürlerin gecikmesi yada başarılarının azalması gibi morbidite ve mortaliteyi artıran durumlardan dolayı rutin uygulanmasını önermemeye başlamıştır6–10. Yine birçok çalışma göstermiştir ki; penetran spinal yaralanmalarda spinal immobilizasyon maliyet etkinlik açısından uygun değildir ve mortalite ve morbiditeyi azaltmamaktadır11–13.

description: The occurrence of the inverse Compton catastrophe when the synchrotron brightness temperature exceeds a threshold value, usually estimated to be 10^{12} K, appears to be in contradiction with observation because: (i) the threshold is substantially exceeded by several intra-day variable radio sources, but the inverse Compton emission is not observed, (ii) powerful, extra-galactic radio sources of known angular size do not appear to congregate close to the predicted maximum brightness temperature. We re-examine the parameter space available to synchrotron sources using a population of monoenergetic electrons, in order to see whether the revised threshold temperature is consistent with the data. The electron distribution and the population of each generation of scattered photons are computed using spatially averaged equations. We confirm our previous finding that intrinsic brightness temperatures T_{\rm B}~10^{14} K can occur without catastrophic cooling. We show that substantially higher temperatures cannot be achieved either in transitory solutions or in solutions that balance losses with a powerful acceleration mechanism. Depending on the observing frequency, we find strong cooling can set in at a range of threshold temperatures and the imposition of the additional constraint of equipartition between particle and magnetic field energy is not warranted by the data. Postulating a monoenergetic electron distribution, which approximates one that is truncated below a certain Lorentz factor, γ_{min}, alleviates several theoretical difficulties associated with the inverse Compton catastrophe, including those mentioned above.

description: The non-thermal radio emission of main-sequence early-type stars is a signature of stellar magnetism. We present multi-wavelength (1.6-16.7 GHz) ATCA measurements of the early-type magnetic star rho OphC, which is a flat-spectrum non-thermal radio source. The rho OphC radio emission is partially circularly polarized with a steep spectral dependence: the fraction of polarized emission is about 60% at the lowest frequency sub-band (1.6 GHz) while is undetected at 16.7 GHz. This is clear evidence of coherent Auroral Radio Emission (ARE) from the rho OphC magnetosphere. Interestingly, the detection of the rho OphC's ARE is not related to a peculiar rotational phase. This is a consequence of the stellar geometry, which makes the strongly anisotropic radiation beam of the amplified radiation always pointed towards Earth. The circular polarization sign evidences mainly amplification of the ordinary mode of the electromagnetic wave, consistent with a maser amplification occurring within dense regions. This is indirect evidence of the plasma evaporation from the polar caps, a phenomenon responsible for the thermal X-ray aurorae. rho OphC is not the first early-type magnetic star showing the O-mode dominated ARE but is the first star with the ARE always on view.

description: Let S be an operator system -- a self-adjoint linear subspace of a unital C*-algebra A such that contains 1 and A=C*(S) is generated by S. A boundary representation for S is an irreducible representation πof C*(S) on a Hilbert space with the property that $π\restriction_S$ has a unique completely positive extension to C*(S). The set $\partial_S$ of all (unitary equivalence classes of) boundary representations is the noncommutative counterpart of the Choquet boundary of a function system $S\subseteq C(X)$ that separates points of X. It is known that the closure of the Choquet boundary of a function system S is the Silov boundary of X relative to S. The corresponding noncommutative problem of whether every operator system has "sufficiently many" boundary representations was formulated in 1969, but has remained unsolved despite progress on related issues. In particular, it was unknown if $\partial_S$ is nonempty for generic S. In this paper we show that every separable operator system has sufficiently many boundary representations. Our methods use separability in an essential way.

description: In today's digitally interconnected world, cybersecurity threats have reached unprecedented levels, presenting a pressing concern for individuals, organizations, and governments. This study employs a qualitative research approach to comprehensively examine the diverse threats of cybersecurity and their impacts across various sectors. Four primary categories of threats are identified and analyzed, encompassing malware attacks, social engineering attacks, network vulnerabilities, and data breaches. The research delves into the consequences of these threats on individuals, organizations, and society at large. The findings reveal a range of key emerging threats in cybersecurity, including advanced persistent threats, ransomware attacks, Internet of Things (IoT) vulnerabilities, and social engineering exploits. Consequently, it is evident that emerging cybersecurity threats pose substantial risks to both organizations and individuals. The sophistication and diversity of these emerging threats necessitate a multi-layered approach to cybersecurity. This approach should include robust security measures, comprehensive employee training, and regular security audits. The implications of these emerging threats are extensive, with potential consequences such as financial loss, reputational damage, and compromised personal information. This study emphasizes the importance of implementing effective measures to mitigate these threats. It highlights the significance of using strong passwords, encryption methods, and regularly updating software to bolster cyber defenses.

description: We consider a Moyal plane and propose to make the noncommutativity parameter Θ^{μν} bifermionic, i.e., composed of two fermionic (Grassmann odd) parameters. The Moyal product then contains a finite number of derivatives, which allows to avoid difficulties of the standard approach. As an example, we construct a two-dimensional noncommutative field theory model based on the Moyal product with a bifermionic parameter and show that it has a locally conserved energy-momentum tensor. The model has no problems with the canonical quantization and appears to be renormalizable.

description: We have investigated the directional dichroism of magnetic resonance spectra in the polar ferromagnet GaV$_4$S$_8$. While four types of structural domains are energetically degenerated under zero field, the magnetic resonance for each domain is well separated by applying magnetic fields due to uniaxial magnetic anisotropy. Consequently, the directional dichroism as large as 20 % is clearly observed without domain cancellation. The present observation therefore demonstrates that not only magnetoelectric mono-domain crystals but also magnetoelectric multi-domain specimens can be used to realize microwave (optical) diodes owing to the lack of inversion domains.

description: In this study, we employ the homogeneous balance method to obtain an analytical solution to the Balitsky-Kovchegov equation with running coupling. We utilize two distinct prescriptions of the running coupling scale, namely the saturation scale dependent running coupling and the dipole momentum dependent running coupling. By fitting the proton structure function experimental data, we determine the free parameters in the analytical solution. The resulting $χ^{2}/d.o.f$ values are determined to be $1.07$ and $1.43$, respectively. With these definitive solutions, we are able to predict exclusive $J/ψ$ production, and demonstrate that analytical solutions with running coupling are in excellent agreement with $J/ψ$ differential and total cross section. Furthermore, our numerical results indicate that the analytical solution of the BK equation with running coupling can provide a reliable description for both the proton structure function and exclusive vector meson production.

Structure and expression of phenylalanine ammonia-lyase-encoding genes in hybrid poplar
Creators: name: Molitor, Elizabeth K.
Publisher: name: University of British Columbia
Year: 2009

description: Genomic PAL sequences were isolated from a hybrid poplar genomic library. Three PAL genes were identified, two similar to each other {PALI and PAL2) and one diverged (PALS). PAL1 and PAL2were placed onto a poplar linkage map. The 3' and 5' regions of these two genes were sequenced, compared, and examined for functional motifs. An interesting motif was a promoter sequence conserved between PAL1 and PAL2, which is similar to AC boxes found in the promoters of other phenylpropanoid genes. The single intron was identified in both PAL1 and PAL2 and surrounding sequences compared for the two genes. The intron's position is conserved when PAL1 and PAL2are compared to each other and to other plant PAL genes. However, PALT and PAL2 possess introns of the same size, which has not been observed for any other plant PAL gene family. Expression of these genes was also examined. The promoters of PAL1 and PAL2 were fused to the reporter gene GUS and transformed into tobacco, where they directed essentially identical patterns of expression in vascular tissues and in ovules. No evidence of differential expression of PAL1, PAL2, or PAL3 was found in these transgenic tobacco or in comparative Northern blot analyses of RNA extracted from various poplar tissues. Seasonal variation in levels of PAL protein and PAL mRNA in bud/leaf and secondary xylem of poplar was investigated using Western and Northern blot analysis. PAL mRNA ievels were highest in leaves in March, and PAL protein levels were highest in leaves in April. In secondary xylem, PAL protein levels were highest in May.

description: The transverse momentum dependence of the anisotropic flow $v_2$ for $π$, $K$, nucleon, $Λ$, $Ξ$ and $Ω$ is studied for Au+Au collisions at $\sqrt{s_{\rm NN}} = 200$ GeV within two independent string-hadron transport approaches (RQMD and UrQMD). Although both models reach only 60% of the absolute magnitude of the measured $v_2$, they both predict the particle type dependence of $v_2$, as observed by the RHIC experiments: $v_2$ exhibits a hadron-mass hierarchy (HMH) in the low $p_T$ region and a number-of-constituent-quark (NCQ) dependence in the intermediate $p_T$ region. The failure of the hadronic models to reproduce the absolute magnitude of the observed $v_2$ indicates that transport calculations of heavy ion collisions at RHIC must incorporate interactions among quarks and gluons in the early, hot and dense phase. The presence of an NCQ scaling in the string-hadron model results suggests that the particle-type dependencies observed in heavy-ion collisions at intermediate $p_T$ might be related to the hadronic cross sections in vacuum rather than to the hadronization process itself.

description: We study nonlinear matter models compatible with radiative Robinson--Trautman spacetimes and analyze their stability and well-posedness. The results lead us to formulate a conjecture relating the (in)stability and well/ill-posedness to the character of singularity appearing in the solutions. We consider two types of nonlinear electrodynamics models, namely we provide a radiative ModMax solution and extend recent results for the RegMax model by considering the magnetically charged case. In both cases, we investigate linear perturbations around stationary spherically symmetric solutions to determine the stability and principal symbol of the system to argue about well-posedness of these geometries. Additionally, we consider a nonlinear sigma model as a source for Robinson--Trautman geometry. This leads to stationary solutions with toroidal (as opposed to spherical) topology thus demanding modification of the analysis.

Such priors are often motivated by the invariance argument of Jeffreys (1961). Revisiting this work, however, we highlight a caveat that Jeffreys himself noticed; namely that biased estimators can result from inducing dependence between parameters a priori. In a similar way, we show that conjugate priors for linear regression, which induce prior dependence, can lead to such underestimation in the Bayesian high-dimensional regression setting. Following Jeffreys, we recommend as a remedy to treat regression coefficients and the error variance as independent a priori. Using such an independence prior framework, we extend the Spike-and-Slab Lasso of Rockova and George (2018) to the unknown variance case. This extended procedure outperforms both the fixed variance approach and alternative penalized likelihood methods on simulated data. On the protein activity dataset of Clyde and Parmigiani (1998), the Spike-and-Slab Lasso with unknown variance achieves lower cross-validation error than alternative penalized likelihood methods, demonstrating the gains in predictive accuracy afforded by simultaneous error variance estimation.

description: We study the correlations between the jet ejection event and changes in the continuum emission of the radio-loud galaxy 3C 390.3, using the archived monitoring data in radio, optical and X-ray. We present evidence for the link between the variable optical continuum and a stationary radio feature in the jet. The ejection of radio components happens during, or after, the dip in the X-ray light curve. Moreover, during the X-ray dip the flux variability is significantly reduced while the hardness ratio and its variance becomes harder. These findings strengthen the idea of similarity between active galactic nuclei (AGN) and microquasars, pointing towards a common physical mechanism acting in the disk-jet system. Other similarities are also discussed on the basis of comparision between 3C 390.3 and the microquasars GRS 1915+105 and Cyg X-1. If the analogy (based on linear mass scaling) between the ejection rates of the microquasar GRS 1915+105 and 3C 390.3 is correct, then the rate of ejections in 3C 390.3 should vary between ~(0.01 to 1) ejections per year on a time scale of thousand years.

description: Harmonics of the mains frequency (50 Hz) have been systematically observed in the transverse beam spectrum of the Large Hadron Collider (LHC) since the start of its operation in the form of dipolar excitations. In the presence of strong non-linearities such as beam-beam interactions, as many of these power supply ripple tones reside in the vicinity of the betatron tune they can increase the tune diffusion of the particles in the distribution, leading to proton losses and eventually to a significant reduction of the beam lifetime. The aim of this paper is to determine whether the 50~Hz harmonics have an impact on the beam performance of the LHC. A quantitative characterization of the ripple spectrum present in the operation of the accelerator, together with an understanding of its source is an essential ingredient to also evaluate the impact of the 50~Hz harmonics on the future upgrade of the LHC, the High Luminosity LHC (HL-LHC). To this end, simulations with the single-particle tracking code, SixTrack, are employed including a realistic ripple spectrum as extracted from experimental observations to quantify the impact of such effects in terms of tune diffusion, Dynamic Aperture and beam lifetime. The methods and results of the tracking studies are reported and discussed in this paper.

description: Place recognition is one of the most crucial modules for autonomous vehicles to identify places that were previously visited in GPS-invalid environments. Sensor fusion is considered an effective method to overcome the weaknesses of individual sensors. In recent years, multimodal place recognition fusing information from multiple sensors has gathered increasing attention. However, most existing multimodal place recognition methods only use limited field-of-view camera images, which leads to an imbalance between features from different modalities and limits the effectiveness of sensor fusion. In this paper, we present a novel neural network named LCPR for robust multimodal place recognition, which fuses LiDAR point clouds with multi-view RGB images to generate discriminative and yaw-rotation invariant representations of the environment. A multi-scale attention-based fusion module is proposed to fully exploit the panoramic views from different modalities of the environment and their correlations. We evaluate our method on the nuScenes dataset, and the experimental results show that our method can effectively utilize multi-view camera and LiDAR data to improve the place recognition performance while maintaining strong robustness to viewpoint changes. Our open-source code and pre-trained models are available at https://github.com/ZhouZijie77/LCPR .

description: We model the abundance gradients in the disk of the Milky Way for several chemical elements (O, Mg, Si, S, Ca, Sc, Ti, Co, V, Fe, Ni, Zn, Cu, Mn, Cr, Ba, La and Eu), and compare our results with the most recent and homogeneous observational data. We adopt a chemical evolution model able to well reproduce the main properties of the solar vicinity. We compute, for the first time, the abundance gradients for all the above mentioned elements in the galactocentric distance range 4 - 22 kpc. The comparison with the observed data on Cepheids in the galactocentric distance range 5-17 kpc gives a very good agreement for many of the studied elements. In addition, we fit very well the data for the evolution of Lanthanum in the solar vicinity for which we present results here for the first time. We explore, also for the first time, the behaviour of the abundance gradients at large galactocentric distances by comparing our results with data relative to distant open clusters and red giants and select the best chemical evolution model model on the basis of that. We find a very good fit to the observed abundance gradients, as traced by Cepheids, for most of the elements, thus confirming the validity of the inside-out scenario for the formation of the Milky Way disk as well as the adopted nucleosynthesis prescriptions.

description: The spectrum of how much or how little organizational processes should be automated has long been debated. As the world undergoes a digital transformation where contactless and frictionless are promoted as two aspects that should be honored, many academics are questioning both the frenetic deployment of digital transformation in learning and teaching environments (e.g., face-to-face classrooms, library and academic office spaces, and laboratories, virtual/hybrid modalities, etc.) and its corresponding validity to students. Indeed, little consultation seems to have taken place with the necessary stakeholders, such as academics, students, instructional designers and pedagogical experts, during and after the COVID-19 pandemic. Rather, discussions and decisions appear to have been reactive regarding which modalities of teaching delivery might be the best in a given context, based on operational scenarios directly linked to financials, such as student recruitment trends, and local legislative changes affecting international students. Furthermore, many academic faculty and a great number of corresponding auxiliary staff have found themselves in the unemployment queue. This paper seeks to present the possibilities that AI-based systems may bring to higher education, but in so doing, point to the harmonization required to offer the most appropriate solutions to the needs of both students and teachers, as well as university administration. Education is not a commodity, although it has been treated as one. We are not advocating for an open market which offers “free education” for all, though we wish for everyone to have adequate access to education. But we are certainly advocating for a future in which students and teachers are central to the learning and teaching environment, not relegated to a passive role nor exploited. This article uses Shiv Ramdas’ short science fiction story, “The Trolley Solution”, to work through the future possibilities of AI in higher education.

description: We study in this paper the dynamics of quantum nanoelectronic resonant tunneling diodes (RTDs) as excitable neuromorphic spike generators. We disclose the mechanisms by which the RTD creates excitable all-or-nothing spikes and we identify a regime of bursting in which the RTD emits a random number of closely packed spikes. The control of the latter is paramount for applications in event-activated neuromorphic sensing and computing. Finally, we discuss a regime of multi-stability in which the RTD behaves as a memory. Our results can be extended to other devices exhibiting negative differential conductance.

description: Given a conditional sentence "P=>Q" (if P then Q) and respective facts, four different types of inferences are observed in human reasoning. Affirming the antecedent (AA) (or modus ponens) reasons Q from P; affirming the consequent (AC) reasons P from Q; denying the antecedent (DA) reasons -Q from -P; and denying the consequent (DC) (or modus tollens) reasons -P from -Q. Among them, AA and DC are logically valid, while AC and DA are logically invalid and often called logical fallacies. Nevertheless, humans often perform AC or DA as pragmatic inference in daily life. In this paper, we realize AC, DA and DC inferences in answer set programming. Eight different types of completion are introduced and their semantics are given by answer sets. We investigate formal properties and characterize human reasoning tasks in cognitive psychology. Those completions are also applied to commonsense reasoning in AI.

description: A double-layered perovskite oxide Sr$_3$Mo$_2$O$_7$ is considered a "hidden ladder" system with wide and narrow bands near the Fermi level, for which high-$T_{\rm c}$ superconductivity is expected. However, the difficulty in synthesis, especially in the preparation of samples without oxygen deficiency, can hinder the observation of superconductivity. In this study, we constructed a double-layer SrMoO$_3$ block through artificial superlattices with the insulating SrTiO$_3$ block, (SrMoO$_3$)$_m$/(SrTiO$_3$)$_t$ ($m = 2, 4$; $t = 4$). First-principles calculations for bilayered SrMoO$_3$ ($m = 2$) exhibit a wide-narrow band structure near the Fermi level, which bears a close resemblance to Sr$_3$Mo$_2$O$_7$. The dispersion along the $k_z$ direction is strongly suppressed by increasing the number of the SrTiO$_3$ layers, $t$. However, no superconductivity is observed down to 0.1 K. We discuss the absence of the superconductivity for the present films on the basis of results of scanning transmission electron microscopy and band structure calculations.
