description: We investigate radiatively inefficient accretion flow models for Sgr A*, the supermassive black hole in our Galactic Center, in light of new observational constraints. Confirmation of linear polarization in the submm emission argues for accretion rates much less than the canonical Bondi rate. We consider models with low accretion rates and calculate the spectra produced by a hybrid electron population, consisting of both thermal and nonthermal particles. The thermal electrons produce the submm emission and can account for its linear polarization properties. As noted in previous work, the observed low-frequency radio spectrum can be explained if a small fraction ($\approx 1.5$%) of the electron thermal energy resides in a soft power-law tail. In the innermost region of the accretion flow, turbulence and/or magnetic reconnection events may occasionally accelerate a fraction of the electrons into a harder power-law tail. We show that the synchrotron emission from these electrons, or the Compton up-scattering of synchrotron photons by the same electrons, may account for the X-ray flares observed by {\it Chandra}.

description: Background: World Health Organisation (WHO) Guidelines on Physical Activity, Sedentary Behaviour and Sleep for Children under 5 Years of Age were released in 2019. The aim of this study was to examine the proportion of Chinese kindergarten children who met each individual guideline and each combination of the guidelines and the associations with adiposity. Methods: Participants were 254 kindergarten children aged 4.1-6.3 years recruited from three kindergartens in urban area of Beijing. Physical activity, sedentary behaviour and sleep duration were assessed using 24-hour accelerometry over three consecutive days. Screen time was reported by parents. Weight and height were measured; and children were categorised into normal weight and overweight/obese groups according to the WHO age- and sex- specific criteria. Frequency analyses were performed to examine the proportion of children meeting individual and combination of these guidelines. Logistics regression analyses were conducted to examine the associations between guideline compliance and adiposity. Results: The proportion of children who met the physical activity (3 hours daily physical activity, including 1 hour daily moderate- to vigorous-intensity physical activity (MVPA)), sedentary screen time (<1 hour/day), and sleep guidelines (10-13hours/day) were 65.4%, 88.2% and 29.5%, respectively; only 15.0% met all three guidelines and 2.7% did not meet any of the guidelines. Not meeting the physical activity guideline, sleep guideline, or combination of any two guidelines, or all three guidelines was not associated with overweight or obesity; however, children who did not meet the sedentary screen time guidelines were at higher risk for overweight and obesity (odds ratio=3.76, 95% CI: 1.50-9.45). Conclusions: In our study, only a small proportion of children met all three guidelines. Most Chinese kindergarten children met physical activity guidelines or screen time guidelines, whereas fewer children met sleep guideline. Not meeting sedentary screen time guidelines was associated with adiposity, which warrant further interventions for limiting screen time in young children.

description: A paradigmatic algorithm for online learning is the Hedge algorithm by Freund and Schapire. An allocation into different strategies is chosen for multiple rounds and each round incurs corresponding losses for each strategy. The algorithm obtains a favorable guarantee for the total losses even in an adversarial situation. This work presents quantum algorithms for such online learning in an oracular setting. For $T$ time steps and $N$ strategies, we exhibit run times of about $O \left ({\rm poly} (T) \sqrt{N} \right)$ for estimating the losses and for betting on individual strategies by sampling. In addition, we discuss a quantum analogue of the Sparsitron, a machine learning algorithm based on the Hedge algorithm. The quantum algorithm inherits the provable learning guarantees from the classical algorithm and exhibits polynomial speedups. The speedups may find relevance in finance, for example for hedging risks, and machine learning, for example for learning generalized linear models or Ising models.

description: A narrow state, which we label DsJ(2458)+, with mass 2458.0 +/- 1.0(stat.) +/- 1.0(syst.) MeV/c^2, is observed in the inclusive Ds+ pi0 γ$ mass distribution in 91 fb-1 of e^+e^- annihilation data recorded by the BABAR detector at the PEP-II asymmetric-energy e^+e^- storage ring. The observed width is consistent with the experimental resolution. The data favor decay through Ds*(2112)+ pi0 rather than through DsJ*(2317)+ gamma. An analysis of Ds+ pi0 data accounting for the influence of the DsJ(2458)+ produces a DsJ*(2317)+ mass of 2317.3 +/- 0.4(stat.) +/- 0.8(syst.) MeV/c^2.

description: Backgrounds: There is an absence of information about the associations between maternal employment and children's dietary patterns (DP), physical activity (PA), and sedentary behaviour (SB) in the context of low-to-middle-income countries (LMIC). Purpose: To explore the DP, PA, and SB of children and adolescents (6-18 years) of mothers differing in employment status within Bangladeshi urban families. Methods: A qualitative design and purposive snowball sampling were used. Semi-structured telephone interviews were conducted with 22 employed and not employed mothers. Data were analyzed using Braun and Clark’s thematic analysis. A combination of inductive and deductive techniques was used to generate codes. Results: The interviews identified 5 major themes. Breakfast skipping, eating instant and non-homemade food is common for the children of employed mothers. Mothers, regardless of employment status, reported challenges in encouraging children to eat vegetables. The scope of PA is limited due to environmental facilities. Employed mothers discourage adolescent girls to play outside due to insecurity as well as socio-cultural reasons. Children use screen-based devices mainly for online classes, watching movies/cartoons, and playing games. Children use devices more often when the mother is at work and sometimes employed mothers allow extra time on smartphones/tablets on weekends to keep their children occupied. Conclusion: Differences in DP, PA and SB are found between children of employed and not employed mothers. Gender differences are evident in the participation of PA. These results may guide future quantitative research to address the problems experienced by working mothers in urban areas of LMICs. Funding: This research did not receive any financial support from any organization.

description: The proof of the failure of the ladder approximation to QCD is given in manifestly gauge-invariant way. This proof is valid for the full gluon propagator and for all types of quarks. The summation of the ladder diagrams within the Schwinger-Dyson integral equation for the quark-gluon vertex, on account of the corresponding Slavnov-Taylor identity, provides an additional constraint on the quark Schwinger-Dyson equation itself in the ladder approximation. It requires that there is neither running nor current quark masses in the ladder approximation. Thus, all the results based on the nontrivial (analytical or numerical) solutions to the quark Schwinger-Dyson equation in the ladder approximation should be reconsidered, and its use in the whole energy/momentum range should be abandoned.

description: We consider the dynamics of reasoning by general rules (theories) and by specific cases (analogies). When an agent faces an exogenous process, we show that, under mild conditions, if reality happens to be simple, the agent will converge to adopt a theory and discard analogical thinking. If, however, reality is complex, the agent may rely on analogies more than on theories. By contrast, when the agent is a player in a large population coordination game, and the process is generated by all players' predictions, convergence to a theory is much more likely. This may explain how a large population of players selects an equilibrium in such a game, and how social norms emerge. Mixed cases, involving noisy endogenous processes are likely to give rise to complex dynamics of reasoning, switching between theories and analogies.

description: Background: The benefits of organised sport and physical activity are important for priority population groups including Indigenous children. To overcome the cost barrier, the New South Wales (NSW) government state-wide Active Kids program, supports the costs associated with registration and membership. Program Delivery: All school-enrolled children (1.2 million) aged 5-18 years in NSW are eligible for a $100 voucher. At registration, parent/carers report the child’s socio-demographic characteristics, physical activity and sport participation. Evaluation: Mixed-methods, pragmatic evaluation integrated within the design of Active Kids provides a unique opportunity to understand patterns of participation behaviors and correlates associated with participation, voucher uptake and program reach. This study aimed to investigate socio-demographic factors associated with organised sport and physical activity participation among Indigenous children. In 2018, 671,375 children registered, with 36,129 (5.4%) identifying as Indigenous. More Indigenous children than non-Indigenous children met the physical activity guidelines. Indigenous children had greater odds of meeting physical activity guidelines across all socio-economic quartiles, whilst non-Indigenous children odds reduced with social disadvantage. Indigenous children were less likely to participate in sport at least twice a week and Indigenous children living in major cities had higher sport participation levels compared with those living in outer regional and remote areas. Conclusions: Active Kids achieved population representative reach among Indigenous children, whose physical activity levels were higher than non-Indigenous children across all socioeconomic quartiles. Active Kids has potential to supplement Indigenous children’s physical activity levels using organised sessions and reduce sport drop-out among older children. Funding: The SPRINTER research group is a strategic research partnership between the University of Sydney and the Office of Sport NSW government. SPRINTER receives funding to conduct a breadth of research and evaluation work which includes Active Kids.

description: We argue that, in the presence of uncertainty, the notion of Pareto dominance is not as compelling as under certainty. In particular, voluntary trade that is based on differences in tastes is commonly accepted as favorable, because no agent involved in it can be wrong about her tastes. By contrast, voluntary trade that is based on incompatible beliefs may indicate that at least one agent is wrong about her beliefs. We propose a weaker, No-Betting, notion of Pareto domination, which requires, on top of unanimity of preference, the existence of shared beliefs that can rationalize such preference for each agent.

description: Accurate quantum chemistry simulations remain challenging on classical computers for problems of industrially relevant sizes and there is reason for hope that quantum computing may help push the boundaries of what is technically feasible. While variational quantum eigensolver (VQE) algorithms may already turn noisy intermediate scale quantum (NISQ) devices into useful machines, one has to make all efforts to use the scarce quantum resources as efficiently as possible. We combine the so-called seniority-zero, or paired-electron, approximation of computational quantum chemistry with techniques for simulating molecular chemistry on gate-based quantum computers and obtain a very resource efficient quantum simulation algorithm. While some accuracy is lost through the paired-electron approximation, we show that using the freed-up quantum resources for increasing the basis set can lead to more accurate results and reductions in the necessary number of quantum computing runs by several orders of magnitude, already for a simple system like lithium hydride. We also discuss an error mitigation scheme based on post-selection which shows an attractive scaling when the given Hamiltonian format is considered, increasing the viability of its NISQ implementation.

description: Sgr A*, the putative black hole in our Galactic Center (GC), is extraordinary dim in all frequencies. Apparently the black hole is unable to accrete at the Bondi accretion rate for some reason. Another mystery of Sgr A* is the recently discovered large magnitude and short duration X-ray flares (Baganoff et al. 2001). Here we point out that X-ray flares should be expected from star passages through an inactive (i.e. formerly accreting) disk. There are thousands of stars in Sgr A* stellar cluster, and each star will pass through the disk twice per orbit. A shock hot enough to emit X-rays is formed around the star when the latter is inside the disk. We develop a simple yet somewhat detailed model for the X-ray emission from the shock. The duration of the flares, their X-ray spectra, frequency of events, and weakness of emission in the radio and near infra-red appear to be consistent with the available observations of X-ray flares. We therefore suggest that at least a fraction of the observed flares is due to the star-disk passages. Such star-disk flares are also of interest in the nuclei of nearby inactive galaxies, especially in connection with perspective Constellation-X and XEUS X-ray missions.

description: The distribution and appearance of nuclei are essential markers for the diagnosis and study of cancer. Despite the importance of nuclear morphology, there is a lack of large scale, accurate, publicly accessible nucleus segmentation data. To address this, we developed an analysis pipeline that segments nuclei in whole slide tissue images from multiple cancer types with a quality control process. We have generated nucleus segmentation results in 5,060 Whole Slide Tissue images from 10 cancer types in The Cancer Genome Atlas. One key component of our work is that we carried out a multi-level quality control process (WSI-level and image patch-level), to evaluate the quality of our segmentation results. The image patch-level quality control used manual segmentation ground truth data from 1,356 sampled image patches. The datasets we publish in this work consist of roughly 5 billion quality controlled nuclei from more than 5,060 TCGA WSIs from 10 different TCGA cancer types and 1,356 manually segmented TCGA image patches from the same 10 cancer types plus additional 4 cancer types.

description: Gaussian states -- or, more generally, Gaussian operators -- play an important role in Quantum Optics and Quantum Information Science, both in discussions about conceptual issues and in practical applications. We describe, in a tutorial manner, a systematic operator method for first characterizing such states and then investigating their properties. The central numerical quantities are the covariance matrix that specifies the characteristic function of the state, and the closely related matrices associated with Wigner's and Glauber's phase space functions. For pedagogical reasons, we restrict the discussion to one-dimensional and two-dimensional Gaussian states, for which we provide illustrating and instructive examples.

description: Response time is used to interpret choice in decision problems. It is first establishes that there is a correlation between short response time and choices that are clearly a mistake. It is then determines whether a correlation also exists between response time and behavior that is inconsistent with some standard theories of decision making. The lack of such a correlation is interpreted to imply that such behavior does not reflect a mistake. It is also shown that a typology of slow and fast responders may, in some cases, be more useful than standard typologies.
title: Biosynthesis and metabolism of selected organofluorine compounds
Creators: name: Rodil García, Andrea
Publisher: name: University of St Andrews

description: The St Andrews group has recently developed a range of novel fluorinated motifs, which include all-cis fluorocyclohexanes, difluoro oxy- and thio- ethers and α,β,β-trifluorocyclopropanes. Fluorinated motifs are often sought after in medicinal chemistry, and it became one of the aims of this thesis to explore these new motifs in order to assess their validity for drug discovery programmes. The metabolic stability of each motif was probed in incubations with Cunninghamella elegans. This fungus is well known for its ability to biotransform xenobiotics mimicking the mammalian P₄₅₀ profile, and thus, providing a useful model for metabolic vulnerability. This showed that the all-cis cyclohexyl derivatives were increasingly stable to the action of P₄₅₀’s with increasing fluorine substitution. The α,α-difluoro thioethers showed oxidation to sulfoxides and sulfones, and the difluorooxy analogue showed a rapid biodegradation into the corresponding acetate ester. The studied α,β,β-trifluorocyclopropanes proved challenging to isolate and identify, but it could be established that the fluorinated motif remained intact after the incubations. The enantioselectivity with which C. elegans transforms the products was explored by chiral HPLC, which allowed an estimation of the enantiomeric resolution of racemates, and also the enantioselectivity of sulfoxide formation. In both cases selectivities were relatively low. Additionally, the lipophilicity of the fluorinated motifs was calculated by reverse-phase HPLC. A general trend was that increasing fluorination led to increased polarity. A second aim was to explore the fluorometabolite biosynthesis in Streptomyces sp. MA37, isolated in Ghana (2014), which contains an active fluorinase. The metabolic pathway in Streptomyces sp. MA37 branches at 5-fluororibose phosphate (5-FDRP), allowing the formation of 5-fluoro-2,3,4-trihydroxypentanoic acid (5-FHPA) and other unknown metabolites. Each of the steps leading to 5-FHPA was studied, and the biotransformation was reconstituted in vitro. The production of fluorometabolites by Streptomyces sp. MA37 was investigated by carrying out cell-free and whole cell feeding experiments with [5’,5’-²H₂]-5’-FDA. Incorporation into the fluorometabolites from [5’,5’-²H₂]-5’-FDA was successful.

description: The existence of cooling flows in the center of galaxy clusters has always been a puzzle, and in particular the fate of the cooling gas, since the presence of cold gas has never been proven directly. X-ray data from the satellites Chandra and XMM-Newton have constrained the amount of cooling, and it was realized that feedback and heating from a central AGN and its jets could reduce the amount of cold gas. Recently, a few central galaxies of cooling flow clusters have been detected in the CO lines. For the first time, we show IRAM interferometer maps of CO(1-0) and CO(2-1) emission in a cooling flow, showing a clear association of the cold gas (at about 20K) with the cooling flow. This shows that although the AGN provides a feedback heating, the cooling phenomenon does occur, with about the expected rate.

description: Identifying the atomic structure of organic-inorganic interfaces is challenging with our current research tools. Interpreting the structure of complex molecular adsorbates from microscopy images can be difficult, and using atomistic simulations to find the most stable structures is limited to partial exploration of the potential energy surface due to the high-dimensional phase space. In this study, we present the recently developed Bayesian Optimization Structure Search (BOSS) method as an efficient solution for identifying the structure of non-planar adsorbates. We apply BOSS with density-functional theory simulations to detect the stable adsorbate structures of (1S)-camphor on the Cu(111) surface. We identify the optimal structure among 8 unique types of stable adsorbates, in which camphor chemisorbs via oxygen (global minimum) or physisorbs via hydrocarbons to the Cu(111) surface. This study demonstrates that new cross-disciplinary tools, like BOSS, facilitate the description of complex surface structures and their properties, and ultimately allow us to tune the functionality of advanced materials.

description: One of the principal legal cases that became a part of the desegregation struggle in higher education was the case of Kenneth Adams, et al., v. Elliott L. Richardson. Adams was a comprehensive class action suit that charged the Department of Health, Education and Welfare with defaulting in its legal responsibility to enforce Title VI of the U.S. Civil Rights Act of 1964, and permitting ten states to receive Federal funds while continuing to operate racially dual systems of higher education. The purpose of this study was to analyze the effect of the Adams mandate on deans in four-year public institutions of higher education in two of the original ten Adams states. These two states were Maryland and Virginia. The study focused specifically on hiring practices as they relate to the position of the dean. Five categories were surveyed: selection committee make-up; methods of job advertisement; processes utilized in the selection of the dean; a comparison of average age and salary of black and white deans; and job responsibility of the dean. The respondent sample included 82 deans (27 black, 55 white) who represented twenty-one four-year public institutions of higher education. Six of the institutions were traditionally black and fifteen were traditionally white. The research instrument was a two-part questionnaire which had a primary focus centering on hiring practices. The secondary issues attempted to survey questions relative to general affirmative action policies. The following conclusions were reached from this study. (1) The proportion of black deans employed in institutions of higher education was not significantly different than before 1973. (2) Traditionally black institutions of higher education continue to provide most of the opportunities for professional upward mobility for a majority of black deans. (3) Affirmative action policies serve as the impetus for hiring blacks as opposed to the Adams case. (4) Although there was no significant difference in the statistical mean of salary between black and white deans, there was a difference in the numerical salary range. (5) The Federal government continues to play a major role in the development and implementation of affirmative action policies. (6) The Adams case had a significant impact on those institutions which did not have previously developed affirmative action plans. (7) Off-campus interest groups, such as the NAACP, have had lobbying impact on institutions regarding affirmative action. (8) The majority of deans employed by the surveyed institutions continue to be white males. (9) Decision makers at the institutions listed in this study, according to the respondents, continue to place more emphasis on the desegregation of the student body than on the desegregation of administrative staffs.

description: During the Eddy Experiment, two synchronous GPS receivers were flown at 1 km altitude to collect L1 signals and their reflections from the sea surface for assessment of altimetric precision and accuracy. Wind speed (U10) was around 10 m/s, and SWH up to 2 m. A geophysical parametric waveform model was used for retracking and estimation of the lapse between the direct and reflected signals with a 1-second precision of 3 m. The lapse was used to estimate the SSH along the track using a differential model. The RMS error of the 20 km averaged GNSS-R absolute altimetric solution with respect to Jason-1 SSH and a GPS buoy measurement was of 10 cm, with a 2 cm mean difference. Multipath and retracking parameter sensitivity due to the low altitude are suspected to have degraded accuracy. This result provides an important milestone on the road to a GNSS-R mesoscale altimetry space mission.

description: We incorporate reference-dependent worker behavior into a search-matching model of the labor market, in which firms have all the bargaining power and productivity follows a log-linear AR(1) process. Motivated by Akerlof (1982) and Bewley (1999), we assume that existing workers’ output falls stochastically from its normal level when their wage falls below a "reference point", which (following K˝oszegi and Rabin (2006)) is equal to their lagged-expected wage. We formulate the model game-theoretically and show that it has a unique subgame perfect equilibrium that exhibits the following properties: existing workers experience downward wage rigidity, as well as destruction of output following negative shocks due to layoffs or loss of morale; newly hired workers earn relatively flexible wages, but not as much as in the benchmark without reference dependence; market tightness is more volatile than under this benchmark. We relate these findings to the debate over the “Shimer puzzle” (Shimer (2005)).
AN ANALYTICAL STUDY OF THE EFFECT OF THE "ADAMS CASE" AFFIRMATIVE ACTION MANDATE ON DEANS IN FOUR-YEAR PUBLIC INSTITUTIONS OF HIGHER EDUCATION IN MARYLAND AND VIRGINIA

description: One of the principal legal cases that became a part of the desegregation struggle in higher education was the case of Kenneth Adams, et al., v. Elliott L. Richardson. Adams was a comprehensive class action suit that charged the Department of Health, Education and Welfare with defaulting in its legal responsibility to enforce Title VI of the U.S. Civil Rights Act of 1964, and permitting ten states to receive Federal funds while continuing to operate racially dual systems of higher education. The purpose of this study was to analyze the effect of the Adams mandate on deans in four-year public institutions of higher education in two of the original ten Adams states. These two states were Maryland and Virginia. The study focused specifically on hiring practices as they relate to the position of the dean. Five categories were surveyed: selection committee make-up; methods of job advertisement; processes utilized in the selection of the dean; a comparison of average age and salary of black and white deans; and job responsibility of the dean. The respondent sample included 82 deans (27 black, 55 white) who represented twenty-one four-year public institutions of higher education. Six of the institutions were traditionally black and fifteen were traditionally white. The research instrument was a two-part questionnaire which had a primary focus centering on hiring practices. The secondary issues attempted to survey questions relative to general affirmative action policies. The following conclusions were reached from this study.

description: Background: Measures to contain the spread of Covid-19 imposed by governments have undoubtedly impacted on preventing its spread but may have also produced longer periods of sedentary living across all segments of society. Purpose: This study examined the sedentary behavior (SB) of Thai adults before and during the Covid-19 pandemic. Methods: The 2019 and 2020 datasets of Thailand’s Surveillance on Physical Activity (SPA) were employed. Face-to-face interviews were employed in SPA2019, whereas online self-administered LimeSurvey was used in SPA2020. A total of 5379 (SPA2019) and 6531 (SPA2020) persons age 18–64 years who had access to the Internet were included in the analysis. The Global Physical Activity Questionnaires (GPAQ) v.2 Thai version was used to measure SB in both face-to-face and online survey Results: Cumulative SB increased from 824 (before the pandemic) to 875 min/day during the pandemic. The odds of accumulating >13 h/day of SB was highest among females, young adults, those who completed post-secondary education, unemployed or working in the non-agriculture sector, having a chronic disease/condition, residing in an urban area, and living in a ‘higher-risk’ pandemic zone. Physical activity (PA) level and the Fit from Home (FFH) intervention was not associated with SB. Conclusion: Measures imposed to contain the spread of Covid-19 infection were significantly associated with lower opportunity of Thai adults for work-related physical movement, and that increased their SB, particularly with the shift from onsite to online working platforms. Funding: SPA is funded by Thai Health Promotion Foundation.

description: Background: Children with cerebral palsy and their families have been impacted by the Covid pandemic situation. Children with CP and their parents are affected by the Covid pandemic, due to lack of formal schooling and lack of rehabilitation, all this has impacted their daily routine. Objective: The survey aimed to study the impact of the Covid pandemic on the accessibility of physical therapy, orthotic aids, and also individual behavior changes in children with cerebral palsy. Methods: Online survey was conducted with the parent using 9 part survey consisting of 26 questions that explored the experiences of children and their families during the lockdown. Demographics data, ambulatory status, lack of access to physiotherapy, orthotic adjustment, surgery, deterioration, and behavior from a parent as collected. Results: 101 children with cerebral palsy with mean age 10.32(5.20) out of which 36(34.3%) were male and 69(65.7%) were females. During lockdown 39 (38.6%) of children were taking regular physiotherapy, 36(35.6%) children had irregular therapy sessions and 26(25.7%) children didn’t take therapy. Due to lack of rehabilitation and lack of inability of the parent to perform exercises, there was deterioration in ambulatory status 57(56.4%) of children. 34(33.7%) children had worsened in the function of the upper limb. 42(41.6%) children had increased joint contracture and deformity. 64(63.4%) children had an increase in muscle stiffness. 45(44.6%) children had changed in behavior due to prolonged sitting at home, increased anger, aggression(n=4,(45.5%), and change in (n=29,28.7%)eating pattern. 30(29.7%) children gain weight more than 5kg due to increased sitting time and sedentary behavior. Conclusion: The survey revealed major consequences, such therapy services were massively interpreted, the parent had difficulties in managing the child therapy at home. There is always a possibility that the pandemic will repeat itself, so our approach toward physical therapy assessment and rehabilitation of children with disabilities needs to be reevaluated and revamped by shifting our focus toward home-based and family-centered care. These approaches can help bridge the gap in the delivery of physical therapy services for children with disabilities in times of COVID-19.

description: We present the first time-resolved spectroscopic study of the cataclysmic variable DW Cancri. We have determined an orbital period of 86.10 +- 0.05 min, which places the system very close to the observed minimum period of hydrogen-rich cataclysmic variables. This invalidates previous speculations of DW Cnc being either a permanent superhumper below the period minimum or a nova-like variable with an orbital period longer than 3 hours showing quasi-periodic oscillations. The Balmer and HeI lines have double-peaked profiles and exhibit an intense S-wave component moving with the orbital period. Remarkably, the Balmer and HeI radial velocity curves are modulated at two periods: 86.10 +- 0.05 min (orbital) and 38.58 +- 0.02 min. The same short period is found in the equivalent width variations of the single-peaked HeII 4686 line. We also present time-resolved photometry of the system which shows a highly-coherent variation at 38.51 min, consistent with the short spectroscopic period. The large number of similarities with the short-period intermediate polar V1025 Cen lead us to suggest that DW Cnc is another intermediate polar below the period gap, and we tentatively identify the photometric and spectroscopic 38-min signals with the white dwarf spin period. DW Cnc has never been observed to undergo an outburst, but it occasionally exhibits low states \~2 mag fainter than its typical brightness level of V~14.5, resembling the behaviour of the high mass-transfer VY Scl stars.
