Resonant Absorption of Bosonic Dark Matter in Molecules

We propose a new class of bosonic dark matter (DM) detectors based on resonant absorption onto a gas of small polyatomic molecules. Bosonic DM acts on the molecules as a narrow-band perturbation, like an intense but weakly coupled laser. The excited molecules emit the absorbed energy into fluorescence photons that are picked up by sensitive photodetectors with low dark count rates. This setup is sensitive to any DM candidate that couples to electrons, photons, and nuclei, and may improve on current searches by several orders of magnitude in coupling for DM masses between 0.2 eV and 20 eV. This type of detector has excellent intrinsic energy resolution, along with several control variables---pressure, temperature, external electromagnetic fields, molecular species/isotopes---that allow for powerful background rejection methods as well as precision studies of a potential DM signal. The proposed experiment does not require usage of novel exotic materials or futuristic technologies, relying instead on the well-established field of molecular spectroscopy, and on recent advances in single-photon detection. Cooperative radiation effects, which arise due to the large spatial coherence of the nonrelativistic DM field in certain detector geometries, can tightly focus the DM-induced fluorescence photons in a direction that depends on the DM's velocity, possibly permitting a detailed reconstruction of the full 3D velocity distribution in our Galactic neighborhood, as well as further background rejection.
Postmortem Examination of Emu Bird (Dromaius novaehollandiae) in Ragunan Zoo

Ragunan Zoo is one of the ex-situ conservation sites in DKI Jakarta to protect the wildlife outside their natural habitat. The emu (Dromaius novaehollandiae) is one of the TMR collection animals originating from Australia. An emu bird named Lebo, aged 19 years, and male sex was found sick on January 12, 2022. Based on physical examination, the emu bird showed clinical symptoms of anorexia, unwilling to eat, lethargic, refusing or difficult to move, unable to lift his head, and inflammation of the right eye. No further examination was performed to determine the diagnosis. Treatments were taken symptomatically, namely the fluid therapy, injection of vitamins and energy sources, antibiotics, and anti-inflammatory. The emu was found dead on February 6, 2022 and a necropsy was performed. Postmortem findings obtained were glossitis, ventriculitis, gizzard erosion, hemorrhagic enteritis, hepatic lipidosis, epicarditis, testicular atrophy, and orchitis. Diagnosis of suspected cause of death is damage and decreased function of various organs of the body.
San trance dance: embodied experience and neurological mechanisms

ABSTRACT The San trance dance has attracted considerable attention in terms of ethnography and rock art, as well as the human capacity for altered states of consciousness. However, its implications for shamanic ritual and associated states of consciousness remain undeveloped without understanding the brain mechanisms involved. Here I integrate previous models of trance with findings from neuroscience and ethnographic reports to outline a neurological model. I suggest that physical exertion leads to activation of the sympathetic nervous system and release of noradrenaline along the spine leading to the feeling of rising energy the San call ! num. Associated hyperventilation activates the amygdala and insula producing fear and the experience of being underwater. With trance, changes in activity of the insula lead to disruption of the right temporal parietal junction, blurring self/other distinctions and leading to body distortion and the experience of flight. Resulting changes in face and body perception are integrated with pre-existing social information in the anterior temporal lobes generating images of human, animal and theriomorphic figures. I also suggest that persistent hunting leads to sustained focus underlying the ability of San men to undergo trance, and makes the Eland central to images of trance in San rock art.
Deep Residual Learning-Based Convolutional Variational Autoencoder For Driver Fatigue Classification

Driving under the influence of fatigue often results in uncontrollable vehicle dynamics, which causes severe and fatal accidents. Therefore, early warning on the fatigue onset is crucial to avoid occurrences of such kind of a disaster. In this paper, the authors have investigated a novel semi-supervised convolutional variational autoencoder-based classification approach to classify the state of the driver. A convolutional variational autoencoder is a generative network. The authors have proposed a discriminative model using convolutional variational autoencoders and residual learning. This approach calculates an intermediate loss base on deep features of the network in addition to the label information in training. The loss obtained by this method helps the training to be more effective on the model and leads to better accuracy in driver fatigue classification. The trained model has managed to classify driver fatigue with higher accuracy (97%) than the other successful models taken into comparison, proving that the proposed method is more practical for computing classification loss for driver fatigue to currently available methods.
An Extragastrointestinal Tumor Diagnosed as a Vaginal Mass during Pregnancy

We report a case of an extragastrointestinal stromal tumor diagnosed as a vaginal mass during pregnancy. The mass was detected during routine examination at 24 weeks of gestation. At 26 weeks, the patient underwent transvaginal ultrasonography and magnetic resonance imaging, which revealed a blood flow-rich mass of approximately 50 × 30 mm in the rectovaginal septum. At 29 weeks of gestation, we resected the mass vaginally and the pathological diagnosis was a gastrointestinal stromal tumor. Chemotherapy was withheld until after full-term birth because the proliferation index of the tumor cells was low. The patient delivered a healthy infant. Imatinib was commenced at 1 month postpartum, with no recurrence or metastasis after 2.5 years. An extragastrointestinal stromal tumor as a vaginal mass in pregnancy has not been reported; however, our case suggests that the tumor should be considered a differential diagnosis of a vaginal mass in pregnancy.

Weak localization effects in granular metals

The weak localization correction to the conductivity of a granular metal is calculated using the diagrammatic technique in the reciprocal grain lattice representation. The properties of this correction are very similar to that one in disordered metal, with the replacement of the electron mean free path $\ell $ by the grain diameter $d$ and the dimensionless conductance $g$ by the tunnelling dimensionless conductance $g_{T}$. In particular, we demonstrate that at zero temperature no conducting phase can exist for dimensions $D\leq 2$. We also analyze the WL correction to magnetoconductivity in the weak field limit.
Role of AMPK in Regulation of Oxaliplatin-Resistant Human Colorectal Cancer

Oxaliplatin is a platinum analog that can interfere with DNA replication and transcription. Continuous exposure to oxaliplatin results in chemoresistance; however, this mechanism is not well known. In this study, oxaliplatin-resistant (OR) colorectal cancer (CRC) cells of HCT116, HT29, SW480 and SW620 were established by gradually increasing the drug concentration to 2.5 μM. The inhibitory concentrations of cell growth by 50% (IC50) of oxaliplatin were 4.40–12.7-fold significantly higher in OR CRC cells as compared to their respective parental (PT) CRC cells. Phospho-Akt and phospho-mammalian target of rapamycin (mTOR) decreased in PT CRC cells but was overexpressed in OR CRC cells in response to oxaliplatin. In addition, an oxaliplatin-mediated decrease in phospho-AMP-activated protein kinase (AMPK) in PT CRC cells induced autophagy. Contrastingly, an increased phospho-AMPK in OR CRC cells was accompanied by a decrease in LC3B, further inducing the activity of glycolytic enzymes, such as glucose transporter 1 (GLUT1), 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) and phosphofructokinase 1 (PFK1), to mediate cell survival. Inhibition of AMPK in OR CRC cells induced autophagy through inactivation of Akt/mTOR pathway and a decrease in GLUT1, PFKFB3, and PFK1. Collectively, targeting AMPK may provide solutions to overcome chemoresistance in OR CRC cells and restore chemosensitivity to anticancer drugs.
Effects of Green Attributes on Residential Price in Taiwan

Taiwan is committed to reducing greenhouse gas emissions and established a green building certification system called the ecology, energy saving, waste reduction, and health (EEWH) system in 1999. However, only 0.44% of the private projects have obtained green building labels in 2017, and almost all of them have expired and not renewed. This study analyzes green attributes of market preferences by using a multi-regression. The results show that green indicators have a significant impact on green premium. That is, greenery, building envelope design, energy conserving air conditioning, construction waste reduction and indoor environment quality have discounted effects on the green premium. But some high-weighed indicators in EEWH are not favored by developers, and therefore have negative impacts on prices, such as building envelope design and energy conserving air conditioning. On the contrary, some low-weighed indicators have positive impacts on prices, such as energy conserving indoor lighting and water conservation, and therefore are already incorporated by developers based on buyers’ demand. It is suggested to modify the weighting of such indicators so that they are in line with buyers’ preferences, which will incentivize developers to incorporate green attributes in future projects that are more valued by buyers.
Fully automated integral field spectrograph pipeline for the SEDMachine: pysedm

Current time domain facilities are discovering hundreds of new galactic and extra-galactic transients every week. Classifying the ever-increasing number of transients is challenging, yet crucial to furthering our understanding of their nature, discovering new classes, and ensuring sample purity, for instance, for Supernova Ia cosmology. The Zwicky Transient Facility is one example of such a survey. In addition, it has a dedicated very-low resolution spectrograph, the SEDMachine, operating on the Palomar 60-inch telescope. This spectrograph’s primary aim is object classification. In practice most, if not all, transients of interest brighter than ∼19 mag are typed. This corresponds to approximately 10–15 targets a night. In this paper, we present a fully automated pipeline for the SEDMachine. This pipeline has been designed to be fast, robust, stable and extremely flexible. pysedm enables the fully automated spectral extraction of a targeted point source object in less than five minutes after the end of the exposure. The spectral color calibration is accurate at the few percent level. In the 19 weeks since pysedm entered production in early August of 2018, we have classified, among other objects, about 400 Type Ia supernovae and 140 Type II supernovae. We conclude that low resolution, fully automated spectrographs such as the “SEDMachine with pysedm” installed on 2-m class telescopes within the southern hemisphere could allow us to automatically and simultaneously type and obtain a redshift for most (if not all) bright transients detected by LSST within z < 0.2, notably potentially all Type Ia Supernovae. In comparison with the current SEDM design, this would require higher spectral resolution (R ≳ 1000) and slightly improved throughput. With this perspective in mind, pysedm is designed to easily be adaptable to any IFU-like spectrograph.
The absorption-line spectrum of the BL Lacertae object AO 0235+164

Absorption features identified with Mg ii, Mg i, Fe ii, and Mn ii at a redshift z=0.5240 +- 0.0001 have been detected in the optical spectrum of the BL Lacertae object AO 0235+164 during its recent outburst. An absorption doublet lambdalambda5176, 5189 cannot be identified with any likely features at the redshift z=0.524 and is believed to be Mg ii lambdalambda2796, 2803 at z=0.85. Thus this is the first BL Lacertae object with more than one absorption-line redshift. The absorption-line spectrum is compared with similar spectra observed in the QSO PHL 938 and in the BL Lacertae object 0735+178, and with Copernicus observations of ultraviolet absorption lines in the spectrum of zeta Oph. The location of the absorbing gas relative to the nonthermal object is discussed. (AIP)
Magnonic quantum Hall effect and Wiedemann-Franz law

We present a quantum Hall effect of magnons in two-dimensional clean insulating magnets at finite temperature. Through the Aharonov-Casher effect, a magnon moving in an electric field acquires a geometric phase and forms Landau levels in an electric field gradient of sawtooth form. At low temperatures, the lowest energy band being almost flat carries a Chern number associated with a Berry curvature. Appropriately defining the thermal conductance for bosons, we find that the magnon Hall conductances get quantized and show a universal thermomagnetic behavior, i.e., are independent of materials, and obey a Wiedemann-Franz law for magnon transport. We consider magnons with quadratic and linear (Dirac-like) dispersions. Finally, we show that our predictions are within experimental reach for ferromagnets and skyrmion lattices with current device and measurement techniques.
Entropic Image Restoration as a Dynamic System with Entropy Operator

Entropy and the classical variational principle of the statistical physics are the effective tools for modeling and solving a lot of applied problems. There are many definitions of "entropy" functions. The book by Kapur (1989) contains some of them. The classical definition of the physical entropy was introduced by L.Boltzmann Boltzmann (1871) and was developed for Fermiand Einstein-statistics Landau & Livshitz (1964). Notion of entropy was introduced for para-statistics that have position between Fermiand Einstein-statistics (Ohnuki & Kamefuchi (1982), Dorofeev et al. (2008)).
A Design and Modelling of Microwave Active Screen Using a Combination of the Rectangular and Periodic Waveguides Modes

A rigorous full wave technique based on the transverse wave concept iterative procedure (WCIP) is used to design and model a microwave active Screen. This approach takes the advantage of the combination of the rectangular and periodic waveguide modes. We demonstrate that 18 × 18 active elements in the closed packages are sufficient to have the same amplification as in the infinite Screen configuration.
Computation of Mean Velocity Distribution in a Turbulent Flow

An approximate method to compute mean velocity profiles in turbulent flows is developed. This approach is based on the equation connecting the Reynolds stress and mean velocity. By using the measured values of pressure drop and average (bulk) flow velocity, such characteristics of a turbulent flow as the mean velocity and Reynolds stress distributions were calculated and compared with the experimental measurements in different pipes and channels for various fluids and gases. These show good agreement for a wide range of Reynolds numbers.
Leaky modes at backward endfire on periodic printed structures

In this work, the transition at backward endfire between bound (nonleaky) and leaky modes on one‐dimensional periodic structures printed on a grounded dielectric substrate is examined. This mode evolution has been characterized for a class of structures with a finite‐width cross section. Such structures support leakage into surface waves as well as into space due to the presence of the substrate. The solutions in this transition region are calculated using an accurate full‐wave moment‐method approach that allows for the determination of both physical and nonphysical solutions, both of which play an important role in the transition region.
The Effects of Temperature Management on Brain Microcirculation, Oxygenation and Metabolism

Purpose: Target temperature management (TTM) is often used in patients after cardiac arrest, but the effects of cooling on cerebral microcirculation, oxygenation and metabolism are poorly understood. We studied the time course of these variables in a healthy swine model.Methods: Fifteen invasively monitored, mechanically ventilated pigs were allocated to sham procedure (normothermia, NT; n = 5), cooling (hypothermia, HT, n = 5) or cooling with controlled oxygenation (HT-Oxy, n = 5). Cooling was induced by cold intravenous saline infusion, ice packs and nasal cooling to achieve a body temperature of 33–35 °C. After 6 h, animals were rewarmed to baseline temperature (within 5 h). The cerebral microvascular network was evaluated (at baseline and 2, 7 and 12 h thereafter) using sidestream dark-field (SDF) video-microscopy. Cerebral blood flow (laser Doppler MNP100XP, Oxyflow, Oxford Optronix, Oxford, UK), oxygenation (PbtO2, Licox catheter, Integra Lifesciences, USA) and lactate/pyruvate ratio (LPR) using brain microdialysis (CMA, Stockholm, Sweden) were measured hourly. Results: In HT animals, cerebral functional capillary density (FCD) and proportion of small-perfused vessels (PSPV) significantly decreased over time during the cooling phase; concomitantly, PbtO2 increased and LPR decreased. After rewarming, all microcirculatory variables returned to normal values, except LPR, which increased during the rewarming phase in the two groups subjected to HT when compared to the group maintained at normothermia. Conclusions: In healthy animals, TTM can be associated with alterations in cerebral microcirculation during cooling and altered metabolism at rewarming.
Candidate RR Lyrae Stars Found in Sloan Digital Sky Survey Commissioning Data

We present a sample of 148 candidate RR Lyrae stars selected from Sloan Digital Sky Survey (SDSS) commissioning data for about 100 deg2 of sky surveyed twice with Δt = 1.9946 days. Although the faint-magnitude limit of the SDSS allows us to detect RR Lyrae stars to large Galactocentric distances (∼100 kpc, or r* ∼ 21), we find no candidates fainter than r* ∼ 20, i.e., farther than ∼65 kpc from the Galactic center. On the assumption that all 148 candidates are indeed RR Lyrae stars (contamination by other species of variable star is probably less than 10%), we find that their volume density has roughly a power-law dependence on Galactocentric radius, R-2.7±0.2, between 10 and 50 kpc and drops abruptly at R ∼ 50–60 kpc, possibly indicating a sharp edge to the stellar halo as traced by RR Lyrae stars. The Galactic distribution of stars in this sample is very inhomogeneous and shows a clump of over 70 stars at about 45 kpc from the Galactic center. This clump is also detected in the distribution of nonvariable objects with RR Lyrae star colors. When sources in the clump are excluded, the best power-law fit becomes consistent with the R-3 distribution found from surveys of bright RR Lyrae stars. These results imply that the halo contains clumpy overdensities inhomogeneously distributed within a smooth R-3 background, with a possible cutoff at ∼50 kpc.
Correlations In Sequences Of First‐Passage Times

The correlations in the sequence of first‐passage times (FPTs) is discussed for two noise‐driven systems. First, results for a perfect integrate‐and‐fire neuron driven by dichotomous process (DP) are reviewed. The FPT sequence in this case corresponds to the interspike intervals separating neural voltage discharges (action potentials). Furthermore, simulation results for the correlations of residence times in a bistable potential driven by a DP are presented. In both systems, the amplitude of correlations in the FPTs sequence decays exponentially with a rate inversely proportional to the correlation time of the driving process. While the neuron model shows a strictly positive correlation between all FPTs, the bistable system displays correlations that oscillate with the lag between intervals.
Major Perioperative Complications of Benign Gynecologic Procedures at a University-Affiliated Hospital

Background: With the increasing use of minimally invasive techniques for gynecologic procedures, women are at a low risk for peri-operative complications. The purpose of this study was to determine the incidence of and risk factors for major intra or postoperative complications among women undergoing benign gynecologic surgeries. Methods: We conducted a retrospective observational study of all women who underwent benign gynecologic surgery in 2016-2017 at a University-Affiliated community hospital. Pregnant women, malignancy cases, and hysteroscopic or minor vulvar procedures were excluded. Primary outcome was composite intraoperative and/or 30-day postoperative complications requiring medical or surgical management. Logistic regression identified significant patient, peri-operative and surgeon risk factors associated with complications. Results: Of 975 patients included, 53 patients experienced major intra or postoperative complications (5.4%). Mean age was 47.7 ± 13.8 years. Mean BMI was 27.1 ± 5.8 kg/m2. Prior abdominal surgery (laparotomy or laparoscopy) (adjusted odds ratio [OR]= 2.01, 95%CI 1.05-3.83) and emergency surgery (adjusted OR= 19.54, 95%CI 2.99-127.54) were significantly associated with major complications. Surgeon volume of 1-2 operative days per month (adjusted OR=0.30, 95%CI 0.10 - 0.87) and age 40-64 years (adjusted OR=0.24, 95%CI 0.11- 0.56) had a protective effect on the risk of major complications. Conclusions: Among patients in our sample, 5.4% experienced major complications from a benign gynecologic surgery. Complications from benign gynecologic surgery are rare, even in the absence of robotic equipment. Center-specific data and a discussion of the increased morbidity associated with with prior abdominal surgery and emergency surgery should be considered for pre-operative patient counselling.
Large-gap Two-dimensional Topological Insulator in Oxygen Functionalized MXene

Two-dimensional (2D) topological insulator (TI) have been recognized as a new class of quantum state of matter. They are distinguished from normal 2D insulators with their nontrivial band-structure topology identified by the $Z_2$ number as protected by time-reversal symmetry (TRS). 2D TIs have intriguing spin-velocity locked conducting edge states and insulating properties in the bulk. In the edge states, the electrons with opposite spins propagate in opposite directions and the backscattering is fully prohibited when the TRS is conserved. This leads to quantized dissipationless "two-lane highway" for charge and spin transportation and promises potential applications. Up to now, only very few 2D systems have been discovered to possess this property. The lack of suitable material obstructs the further study and application. Here, by using first-principles calculations, we propose that the functionalized MXene with oxygen, M$_2$CO$_2$ (M=W, Mo and Cr), are 2D TIs with the largest gap of 0.194 eV in W case. They are dynamically stable and natively antioxidant. Most importantly, they are very likely to be easily synthesized by recent developed selective chemical etching of transition-metal carbides (MAX phase). This will pave the way to tremendous applications of 2D TIs, such as "ideal" conducting wire, multifunctional spintronic device, and the realization of topological superconductivity and Majorana modes for quantum computing.
